      <title>Poor man&#39;s soldering fumes extractor</title>
      <link>https://celso.io/posts/2025/11/23/soldering-smoke-extractor/</link>

      <description>&lt;p&gt;My electronics lab is inside my office at home. It&amp;rsquo;s very convenient for the occasional hacking electronics project. Still, I do a lot of soldering, and breathing those solder fumes in a closed space isn&amp;rsquo;t very healthy, especially during winter when the windows are all closed.&lt;/p&gt;&#xA;&lt;p&gt;Home labs are so prevalent now that brands are paying attention; fume extractors are no longer &lt;a href=&#34;https://store.creality.com/eu/products/creality-fume-extractor&#34;&gt;expensive&lt;/a&gt;. But what&amp;rsquo;s the fun in buying when I can build my own?&lt;/p&gt;</description>

      <description>&lt;p&gt;The computers that I write about on this blog are mostly machines that I owned when I was younger. That changes today. Over the last few months, I’ve been slowly taking free time to work on a machine that I never owned (or could have; they weren’t sold outside the UK), an &lt;a href=&#34;https://en.wikipedia.org/wiki/Acorn_Archimedes&#34;&gt;Acorn Archimedes&lt;/a&gt; A3020.&lt;/p&gt;&#xA;&lt;div class=&#34;caption&#34; style=&#34;&#34;&gt;&#xA;    &#xA;        &#xA;        &lt;img src=&#34;https://celso.io/assets/a3020-1.jpg&#34; /&gt;&#xA;        &#xA;        My Acorn Archimedes A3020&#xA;        &#xA;&lt;/div&gt;&#xA;&#xA;&lt;p&gt;What’s special about this computer to me is its historical relevance. It runs on one of the first ARM RISC processors. More specifically, it runs an &lt;a href=&#34;https://en.wikichip.org/wiki/arm_holdings/microarchitectures/arm250&#34;&gt;ARM 250&lt;/a&gt;, a system-on-chip that includes the 32-bit ARM3 core, along with memory and I/O controllers.&lt;/p&gt;</description>

      <title>Assembling a Retro Chip Tester Pro</title>

      <description>&lt;p&gt;I&amp;rsquo;ve been considering adding a chip tester to my lab for some time now, but I&amp;rsquo;ve never quite taken the plunge. BackBit, whom I know well because I have a BackBit Pro cartridge that I use to load software onto my 8-bit computers, has the &lt;a href=&#34;https://store.backbit.io/product/chip-tester/&#34;&gt;Chip Tester Pro V2&lt;/a&gt;. I was close to buying one, but I found it somewhat expensive, and importing it from the US didn&amp;rsquo;t help, so I waited.&lt;/p&gt;</description>

      <description>&lt;p&gt;This is a quick update from my &lt;a href=&#34;https://celso.io/posts/2025/06/28/toastrack/&#34;&gt;Restoring a ZX Spectrum+ Toastrack&lt;/a&gt; blog.&lt;/p&gt;&#xA;&lt;h2 id=&#34;rgb-is-not-analog-we-need-more-colors&#34;&gt;RGB is not analog, we need more colors&lt;/h2&gt;&#xA;&lt;p&gt;First, I found that the &lt;a href=&#34;https://github.com/hoglet67/RGBtoHDMI/wiki/Bill-of-Materials-%28Analog-Board%29&#34;&gt;6-way IDC analog RGB extender&lt;/a&gt; that I used with the RGB2HDMI adapter wasn&amp;rsquo;t detecting all the colors. Specifically I wasn&amp;rsquo;t seeing the half bright variant of the 3-bit 8 color palette.&lt;/p&gt;&#xA;&lt;div class=&#34;caption&#34; style=&#34;&#34;&gt;&#xA;    &#xA;        &#xA;        &lt;img src=&#34;https://celso.io/assets/toast22.jpg&#34; /&gt;&#xA;        &#xA;        6-way IDC analog RGB extender&#xA;        &#xA;&lt;/div&gt;&#xA;&#xA;&lt;p&gt;As you can see I only have 8 colors.&lt;/p&gt;</description>

      <description>&lt;p&gt;I talk a lot about Commodore machines in this blog; they left a bigger dent in me growing up, but like most kids of my generation living in Portugal in the 80s, the first computers I played with were actually Sinclairs—first my friend&amp;rsquo;s ZX81 and then a ZX Spectrum 48K that my parents offered me. I have many memories of playing games like the &lt;a href=&#34;https://en.wikipedia.org/wiki/Horace_(video_game_series)&#34;&gt;Horace series&lt;/a&gt;, &lt;a href=&#34;https://en.wikipedia.org/wiki/Manic_Miner&#34;&gt;Manic Miner&lt;/a&gt;, &lt;a href=&#34;https://en.wikipedia.org/wiki/Jetpac&#34;&gt;Jetpac&lt;/a&gt;, or &lt;a href=&#34;https://en.wikipedia.org/wiki/Chuckie_Egg&#34;&gt;Chuckie Egg&lt;/a&gt; on my Spectrum.&lt;/p&gt;</description>

      <title>Changing the A1000 fan</title>
      <link>https://celso.io/posts/2025/03/30/a1000-fan/</link>

      <description>&lt;p&gt;I&amp;rsquo;m on a roll upgrading the Amiga 1000. This time, I replaced the PSU fan.&lt;/p&gt;&#xA;&lt;p&gt;The Amiga 1000 PSU uses an ETRI Model 126LH metallic fan that is AC-powered 220/110V. These fans are pretty good, silent, reliable, and used in computers and industrial-grade equipment. However, they all suffer from a common problem: after long years of continuous use, the fan bearing starts developing an annoying grinding noise due to a lack of lubrication. This is a &lt;a href=&#34;https://www.amigalove.com/viewtopic.php?p=16937&#34;&gt;well-known issue&lt;/a&gt; for Amiga 1000 users, and I mentioned that mine also had the same problem in &lt;a href=&#34;https://celso.io/posts/2025/01/26/the-first-perfect-computer/&#34;&gt;another post&lt;/a&gt;.&lt;/p&gt;</description>

      <title>RGB2HDMI for the Amiga 1000</title>
      <link>https://celso.io/posts/2025/03/10/rgb2hdmi/</link>

      <description>&lt;p&gt;On my last post &amp;ldquo;&lt;a href=&#34;https://celso.io/posts/2025/01/26/the-first-perfect-computer/&#34;&gt;the first perfect computer&lt;/a&gt;&amp;rdquo; I mentioned that I wasn&amp;rsquo;t done with the A1000. I finally upgraded it with an internal RGB2HDMI adapter.&lt;/p&gt;&#xA;&lt;p&gt;For those unfamiliar with &lt;a href=&#34;https://github.com/hoglet67/RGBtoHDMI&#34;&gt;RGB2HDMI&lt;/a&gt;, it&amp;rsquo;s a brilliant and affordable open-source project that converts &amp;ldquo;digital&amp;rdquo; RGB video signals from vintage computers into crystal clear HDMI video with very low latency. At its core, there&amp;rsquo;s a combination of a &lt;a href=&#34;https://www.raspberrypi.com/products/raspberry-pi-zero/&#34;&gt;RaspberryPi Zero&lt;/a&gt; running bare-metal &lt;a href=&#34;https://github.com/hoglet67/RGBtoHDMI/tree/master/src&#34;&gt;code&lt;/a&gt; and a &lt;a href=&#34;https://en.wikipedia.org/wiki/Complex_programmable_logic_device&#34;&gt;CPLD&lt;/a&gt; (complex programmable logic device) programmed to do level shifting and pixel sampling on the TTL RGB outputs from a vintage computer and feed the processed data into the Pi&amp;rsquo;s GPIO pins.&lt;/p&gt;</description>

      <title>The first perfect computer</title>

      <description>&lt;p&gt;This is a story about restoring and upgrading a &lt;a href=&#34;https://en.wikipedia.org/wiki/Amiga_1000&#34;&gt;Commodore Amiga 1000&lt;/a&gt;, the first model of the Amiga series.&lt;/p&gt;&#xA;&lt;p&gt;Many of you might be familiar with the popular Amiga 500 or later models, but the Commodore Amiga 1000 was actually the &lt;a href=&#34;https://en.wikipedia.org/wiki/History_of_the_Amiga&#34;&gt;first model&lt;/a&gt; of the Amiga series produced.&lt;/p&gt;&#xA;&lt;p&gt;I consider the A1000 a significant piece of home computing history. Arguably one of the most important machines of the 16-bit revolution period, considered by many to be the first multimedia computer, it marked the beginning of Commodore&amp;rsquo;s last cycle, after the huge success of the C64, in the history of personal computing.&lt;/p&gt;</description>

      <title>Running CP/M on the C128</title>
      <link>https://celso.io/posts/2024/03/03/c128-cpm/</link>

      <description>&lt;p&gt;The &lt;a href=&#34;https://en.wikipedia.org/wiki/CP/M&#34;&gt;CP/M&lt;/a&gt;, short for Control Program/Monitor, was one of the first operating systems of the personal computer revolution. It was launched in 1974, and it celebrates 50 years this year. It was ported and made available for many 8-bit machines with different CPUs and was related to running productivity software. If you ever used CP/M, then, well, I hate to say it, but you&amp;rsquo;re old.&lt;/p&gt;&#xA;&lt;p&gt;I had a brief encounter with CP/M when I was 14 or 15 years old; I can&amp;rsquo;t remember exactly. At the time, I was in high school in Aveiro, and the local computer shop, which I visited daily on my way to the train station, just to stare at the window, the same way a pilgrim would visit and contemplate at a shrine, had two beautiful machines on display: the brand-new Amiga 1000 and a C128D.&lt;/p&gt;</description>

      <title>My finest C64/128 setup so far</title>
      <link>https://celso.io/posts/2024/02/25/c128dcr/</link>

      <description>&lt;p&gt;The C128 is a &lt;a href=&#34;https://www.c64-wiki.com/wiki/Commodore_128&#34;&gt;fascinating&lt;/a&gt; and unusual machine. It was the last 8-bit Commodore machine before the Amiga and co-existed with the C64 series for a while. They sold ~8 million units worldwide (vs ~17 million C64). I never owned one, but I fondly remember playing with one at my friend&amp;rsquo;s place and seeing them in computer shops.&lt;/p&gt;&#xA;&lt;p&gt;&lt;img src=&#34;https://celso.io/assets/c128/c128dcr.jpeg&#34; alt=&#34;&#34;&gt;&lt;/p&gt;&#xA;&lt;p&gt;It&amp;rsquo;s &lt;del&gt;fully&lt;/del&gt; &lt;a href=&#34;https://www.youtube.com/watch?v=Ial2VSAu7tw&#34;&gt;99.8%&lt;/a&gt; backward compatible with its predecessor in C64 mode, but in native C128 mode it takes advantage of its 128 KB RAM, higher clocked 2 MHz 6510 variant (the 8502), and the improved VIC-IIe graphics chip.&lt;/p&gt;</description>

      <description>&lt;p&gt;Filipe Cruz (aka &lt;a href=&#34;https://www.patreon.com/psenough&#34;&gt;psenough&lt;/a&gt;) invited me to &lt;a href=&#34;https://2023.inercia.pt/&#34;&gt;Inércia 2023&lt;/a&gt;, a local Demoscene event organized by the &lt;a href=&#34;https://inercia.pt/&#34;&gt;Associação Inércia&lt;/a&gt; that took place in the infamous &lt;a href=&#34;https://incrivelalmadense.pt/&#34;&gt;Incrível Almadense&lt;/a&gt;. I&amp;rsquo;ve done my fair share of bouncing ball assembly demos in the 80s and others more &lt;a href=&#34;https://github.com/celso/c64&#34;&gt;recently&lt;/a&gt;, but I don&amp;rsquo;t qualify as a demoscener, not even by the lowest standards. Still, I promptly accepted the invitation. I participated in a panel that discussed the struggles and strategies of organizing community events. Then, later in the evening, I told the story about why and how I built my &lt;a href=&#34;https://celso.io/posts/2022/12/28/c64-from-scratch/&#34;&gt;Frankenstein 64&lt;/a&gt;. There is some interception between retrocomputing and the demoscene, so it made sense.&lt;/p&gt;</description>

      <description>&lt;p&gt;The ingenuity of combining open-source and open hardware in retro computing is a force of creativity and marvel these days.&lt;/p&gt;&#xA;&lt;p&gt;One of the conundrums with running old computers nowadays is how you display video. I love CRT monitors; I&amp;rsquo;m a proud owner of a classic &lt;a href=&#34;https://www.c64-wiki.com/wiki/Commodore_1084&#34;&gt;1084S&lt;/a&gt; that I use with my &lt;a href=&#34;https://www.c64-wiki.com/wiki/C128DCR&#34;&gt;C128DCR&lt;/a&gt;, but they&amp;rsquo;re not easy to find in good condition, are expensive, and are increasingly prone to failure with passing years.&lt;/p&gt;</description>

      <title>Building a Frankenstein 64</title>

      <pubDate>Wed, 28 Dec 2022 14:08:00 +0000</pubDate>
      <guid>https://celso.io/posts/2022/12/28/c64-from-scratch/</guid>
      <description>&lt;p&gt;Last year, I decided that I was going to build a &lt;a href=&#34;https://en.wikipedia.org/wiki/Commodore_64&#34;&gt;Commodore 64&lt;/a&gt; from scratch. This is the blog documenting the project.&lt;/p&gt;&#xA;&lt;p&gt;It&amp;rsquo;s no secret that I love &lt;a href=&#34;https://celso.io/retrocomputing/2019/12/23/c64-assembly.html&#34;&gt;fiddling with retro computers&lt;/a&gt;, especially those I owned when I was a kid. When I revisit ancient technologies and hardware that were part of my younger years, I&amp;rsquo;m overwhelmed with that warm nostalgia feeling. But it&amp;rsquo;s not only that. Understanding how old computers work is also educational and helps me look at the modern world with a wiser perspective.&lt;/p&gt;</description>

      <description>&lt;p&gt;It&amp;rsquo;s happening. The Cloudflare Lisbon office is growing, and I&amp;rsquo;m excited to announce we just opened &lt;strong&gt;six new positions&lt;/strong&gt; for a new engineering team we’re creating.&lt;/p&gt;&#xA;&lt;p&gt;We’re specifically looking for candidates based in Lisbon. This team will be working on data insights and special projects for Cloudflare. We operate with small groups of highly motivated and experienced software, data science, and network engineers who like to solve problems, and we work to meet both the challenges of a massively growing customer base and our internal department&amp;rsquo;s needs.&lt;/p&gt;</description>

Unlike most of the others, the C64 had dedicated advanced MOS chips for graphics and sprites (the &lt;a href=&#34;https://en.wikipedia.org/wiki/MOS_Technology_VIC-II&#34;&gt;VIC-II&lt;/a&gt;), sound (the &lt;a href=&#34;https://en.wikipedia.org/wiki/MOS_Technology_6581&#34;&gt;SID&lt;/a&gt;), I/O (the CIA), and many others.&lt;/p&gt;</description>

I had multiple Spectrum and C64 machines in my youth (still own a few today) and at that age, I was somewhat proficient at BASIC, Z80 and 6510 assembly code. I remember the days when all we had were the occasional &lt;a href=&#34;https://en.wikipedia.org/wiki/Input_(magazine)&#34;&gt;programming magazine&lt;/a&gt; in the kiosk and the help of our close-by IRL friends. There was no Internet, no online PDFs, nothing. Access to information was expensive and scarce.&lt;/p&gt;</description>

I guess I’m now seen as the old experienced business guy with grizzled hair who went through a shitload of problems, was able to overcome some, and can probably provide inspirational insights to the next generations. Kind of sad, in a way. It’s either this or they just think I’m a good entertainer.&lt;/p&gt;</description>

      <description>&lt;p&gt;It&amp;rsquo;s a fact that Facebook and Google (including Youtube) own a sizeable chunk of the global internet traffic and their competitive advantage boils down to two things: computing power and data. These two giants&amp;rsquo; core businesses depend exclusively on tracking us to our tiniest move and correlating what they know about us across their products and platforms. And boy, do they know about us.&lt;/p&gt;&#xA;&lt;p&gt;Eric Schmidt once said, &lt;em&gt;“The Internet is the first thing that humanity has built that humanity doesn&amp;rsquo;t understand, the largest experiment in anarchy that we have ever had.”&lt;/em&gt;.&lt;/p&gt;</description>

Antes disso, mais precisamente no dia 4 de Setembro, dia do vigésimo aniversário do SAPO, por motivos que por pudor provavelmente nunca relatarei, tomei em consciência a decisão de o fazer. Horas antes cantava os parabéns com a equipa e apagava as velas do bolo em cima do coreto na Praça José Fontana. Fi-lo com um sorriso postiço, danado com o que o destino me tinha reservado para este dia de celebração. Finalmente entendi, em plenitude, o que era a tal solidão da liderança de que os outros me falavam.&lt;/p&gt;</description>

      <description>&lt;p&gt;A passagem em conselho de ministros da nova lei da cópia privada e consequente próxima muito provável aprovação na assembleia deixou-me muito pouco surpreendido hoje. Enojado, triste, decepcionado mais uma vez com os meus representantes políticos sim, mas não admirado. À terceira é de vez, dizem, especialmente quando à terceira se junta a larga experiência de quem sabe bem que a melhor maneira de fazer passar estas coisas é de fininho, na altura certa, durante Agosto quando país está a banhos, evidentemente, minimizando assim o risco de que o barulho e influência da opinião pública e mais uns quantos que até podiam fazer alguma coisa se traduza no que quer que seja que impeça a sua aprovação. Tiro-lhes o chapéu pela estratégia e inteligência (não é sarcasmo).&lt;/p&gt;</description>

      <description>&lt;p&gt;Miúdo, quanto te conheci eras um chavalo sem futuro, mal te aguentavas nas canelas naquele &lt;em&gt;Pentium&lt;/em&gt; com &lt;em&gt;FreeBSD&lt;/em&gt;, não sabias bem o que querias fazer da vida, não percebias muito nem da &lt;em&gt;Internet&lt;/em&gt; nem de nada, eras apenas um &lt;em&gt;script&lt;/em&gt; de &lt;em&gt;bash&lt;/em&gt; que fazia &lt;em&gt;grep&lt;/em&gt; a um ficheiro. Como? Perdão, base de dados, claro, peço desculpa.&lt;/p&gt;&#xA;&lt;p&gt;Mas safaste-te bem, tinhas gana e paixão, foste bem acompanhado, e davas cartas às alternativas, páginas em &lt;em&gt;Gopher&lt;/em&gt; ou pior: teletexto por X.25. Não tardou e já te vangloriavas pela Usenet dos teus magníficos feitos, das tuas taxas de crescimento, da tua importância para a Internet em Portugal. E de repente veio a glória, convidavam-te para palestras na FCCN, davas entrevistas na rádio, e tenho uma vaga ideia de até te ter visto num programa da Praça da Alegria com o Manuel Goucha, não me lembro bem. Enfim, eras um batráquio presunçoso insuportável, era o que era.&lt;/p&gt;</description>

      <description>&lt;p&gt;So, you know I’m a sucker for vintage computing. I’ve been a proud owner of an original C64, an Amiga 1200, an &lt;a href=&#34;http://arrifana.org/blog/2011/11/uma-prenda-surpreendente/&#34;&gt;Atari 130 XE&lt;/a&gt;, and a &lt;a href=&#34;https://plus.google.com/104373486389798219744/posts/LgkkXrsJcnZ&#34;&gt;ZX-81&lt;/a&gt;, and a bunch of old peripherals and hacks that connect to them all in working condition.&lt;/p&gt;&#xA;&lt;p&gt;But today I got in the mail one very special rarity. It’s an original, unopened, white, brand new, from the warehouse, Amiga 1200 Magic edition sold to me directly by no less than the legendary ex president of Amiga Technologies &lt;a href=&#34;http://www.mos6502.com/friday-commodore/commodore-legends-petro-tyschtschenko/&#34;&gt;Petro Tyschtschenko&lt;/a&gt;.&lt;/p&gt;</description>

      <description>&lt;p&gt;Aproximam-se dois eventos que devo mencionar para os quais fui convidado a exortar sobre certos e determinados temas.&lt;/p&gt;&#xA;&lt;p&gt;Curiosamente e para variar, em ambos elaborarei não sobre SAPO, tecnologia, empreendedorismo ou balões mas sim sobre temáticas radicalmente diferentes. Temos tudo para que corra mal, portanto. Agrada-me.&lt;/p&gt;&#xA;&lt;p&gt;Primeiro, o &lt;a href=&#34;http://tedxist.ist.utl.pt&#34;&gt;TEDxIST&lt;/a&gt;, organizado por alunos do Instituto Superior Técnico para falar sobre… coisas que estão a acontecer nas quais eu acredito muito.&lt;/p&gt;&#xA;&lt;p&gt;Segundo, &lt;a href=&#34;http://worldfailuristscongress.wordpress.com&#34;&gt;World Failurists Congress&lt;/a&gt;, um conceito de conferência absolutamente novo e original que gira à volta de uma característica importantíssima sempre presente em qualquer caso de sucesso, uma em que aparentemente me &lt;a href=&#34;http://saber.sapo.pt/wiki/Celsada&#34;&gt;reconhecem&lt;/a&gt; muita experiência: o redondo falhanço. Reza que o meu nome foi sugerido pelos que que trabalham diretamente comigo, não sei. &lt;/p&gt;</description>

      <title>Connecting a Raspberry Pi to an old 15Khz Arcade Monitor</title>

      <description>&lt;p&gt;The Raspberry Pi has been used all over the world as an excellent emulator box to resuscitate old arcade machines, but with moderate success.&lt;/p&gt;&#xA;&lt;p&gt;You see, if you’re a truly arcade aficionado like me, then you’ll aim for perfection. And perfection means you’ll use the &lt;a href=&#34;http://en.wikipedia.org/wiki/Japan_Amusement_Machinery_Manufacturers_Association&#34;&gt;jamma connector&lt;/a&gt; and the old 15Khz CRT instead of a more modern retro fitted VGA monitor like most people opt to do.&lt;/p&gt;&#xA;&lt;p&gt;Old arcade CRT sets can only accept 15Khz horizontal frequencies using separate RGB signals and a sync line (well, not quite, there are 25 Khz monitors too but they’re uncommon). Ultimarc has an &lt;a href=&#34;http://www.ultimarc.com/monfaq.html&#34;&gt;excellent article about arcade monitors&lt;/a&gt; if you want more details.&lt;/p&gt;</description>

      <description>&lt;p&gt;So, recently I became a member of the home 3D printers early starters community and got myself an Ultimaker.&lt;/p&gt;&#xA;&lt;p&gt;I thought I’d do a time-lapse video of the whole assembly process, including the first 3D print.&lt;/p&gt;&#xA;&lt;p&gt;It took me 3 days to complete the building instructions but the result is pretty awesome.&lt;/p&gt;&#xA;&lt;p&gt;Congratulations to the Ultimaker team for making such a wonderful machine and putting together such great documentation, I still think it’s a miracle this thing actually printed an almost perfect black cube at the first attempt.&lt;/p&gt;</description>

      <description>&lt;p&gt;Há projectos que são invulgares pela motivação que geram nas equipas e nas organizações. São raros e curiosamente surgem fora dos nossos planos tradicionais e lineares, fora das visões condicionadas, dos retiros e dos &lt;em&gt;brainstorms&lt;/em&gt;.&lt;/p&gt;&#xA;&lt;p&gt;Há um ano atrás uma pequena equipa tentou vender-me um conceito de um projecto que lhes surgiu espontaneamente. Agarram-me em 10 minutos. Em poucos dias tiveram a energia suficiente para estruturar essa ideia para que juntos conseguíssemos mobilizar todas as áreas da organização necessárias para concretizar essa visão, e semanas depois o projecto era aprovado e apoiado ao mais alto nível pelo grupo aonde trabalhamos.&lt;/p&gt;</description>

      <description>&lt;p&gt;A SPA, claramente pressionada pela péssima opinião pública que esta proposta de lei está a gerar, publicou um documento intitulado “&lt;a href=&#34;http://www.spautores.pt/assets_live/5192/10_coisas_sobre_c_pia_privada.pdf&#34;&gt;10 coisas que deveria saber sobre a Lei da Cópia Privada&lt;/a&gt;“.&lt;/p&gt;&#xA;&lt;p&gt;Apetece-me desmanchar ponto por ponto deste argumentário barato e manipulativo, mas seria um desperdício do meu tempo, da minha inteligência e da minha energia se o fizesse já.&lt;/p&gt;&#xA;&lt;p&gt;Mas há aqui uma grande conclusão que é preciso mencionar imediatamente.&lt;/p&gt;</description>

      <description>&lt;p&gt;Andei a matutar nas receitas que a &lt;a href=&#34;http://app.parlamento.pt/webutils/docs/doc.pdf?path=6148523063446f764c3246795a5868774d546f334e7a67774c325276593342734c576c756156684a5358526c65433977616d77784d54677457456c4a4c6d527659773d3d&amp;amp;fich=pjl118-XII.doc&amp;amp;Inline=true&#34;&gt;PL118&lt;/a&gt; conseguiria gerar nos moldes em que está a ser proposta.&lt;/p&gt;&#xA;&lt;p&gt;Decidi arregaçar as mangas e fazer umas contas de merceeiro com os dados que consegui arranjar.&lt;/p&gt;&#xA;&lt;p&gt;Para não correr muitos riscos decidi ser extremamente conservador. Estas são as premissas que usei:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Fiz duas análises, uma para 2012 e outra para 2014. O objetivo era provar que os cálculos propostos &lt;a href=&#34;http://arrifana.org/blog/2012/01/proposta-de-lei-118-notas-avulsas-3/&#34;&gt;são absurdos&lt;/a&gt; e desproporcionais em relação à evolução da realidade.&lt;/li&gt;&#xA;&lt;li&gt;Estou a assumir que o mercado vai estar estagnado até 2014 e a venda de PCs, discos rígidos e telemóveis não vai aumentar.&lt;/li&gt;&#xA;&lt;li&gt;&lt;del&gt;Não encontrei &lt;em&gt;forecasts&lt;/em&gt; fiáveis sobre a venda de consolas de jogos, MP3 players (ie: iPods) e outros aparelhos que incluem memórias (ie: iPads), e portanto ignorei por completo estas receitas, devem ser uma fatia grande.&lt;/del&gt;&lt;/li&gt;&#xA;&lt;li&gt;Não inclui todos os dispositivos e suportes, nomeadamente &lt;del&gt;as impressoras, os CDs e os DVDs.&lt;/del&gt; os analógicos.&lt;/li&gt;&#xA;&lt;li&gt;Assumo que a penetração de telemóveis com uma memória de armazenamento vai passar de 50% para 80%.&lt;/li&gt;&#xA;&lt;li&gt;Assumo, conservadoramente, que o tamanho médio de um disco rígido externo, interno ou incluído num computador novo é de 600GB este ano (dados fiáveis) e que será de 2T em 2014 (A &lt;a href=&#34;http://en.wikipedia.org/wiki/Mark_Kryder&#34;&gt;lei de moore adaptada &lt;/a&gt;aos HDDs diz que será mais).&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;A folha de cálculo &lt;a href=&#34;https://docs.google.com/spreadsheet/ccc?key=0AvGEkGo6qRR4dHJaLVFKbWFhcWVlakNmaThiWXZLUnc&#34;&gt;pode ser vista aqui&lt;/a&gt;, para que não sobrem dúvidas.&lt;/p&gt;</description>

      <description>&lt;p&gt;Como já foi amplamente exposto &lt;a href=&#34;http://app.parlamento.pt/webutils/docs/doc.pdf?path=6148523063446f764c3246795a5868774d546f334e7a67774c325276593342734c576c756156684a5358526c65433977616d77784d54677457456c4a4c6d527659773d3d&amp;amp;fich=pjl118-XII.doc&amp;amp;Inline=true&#34;&gt;esta lei&lt;/a&gt; peca também por ter inúmeras incorrecções técnicas e por estar desligada da realidade industrial. Uma das premissas em que esta lei é baseada é falsa e ofensiva e mostra que quem redigiu esta proposta foram, das duas uma, pessoas de boa fé com um desconhecimento total do que estão a falar ou então pessoas que percebem muito bem o que estão a fazer. Eu acredito na primeira, mas nos dois casos é muito grave.&lt;/p&gt;</description>

      <description>&lt;p&gt;A propósito das alternativas para o consumidor caso esta lei seja aprovada.&lt;/p&gt;&#xA;&lt;p&gt;O português não tem grande pachorra para travar lutas por questões de princípio. Dá muito trabalho. A nossa primeira reacção, não fossemos nós os mestres da escapatória, de resto até temos &lt;a href=&#34;http://pt.wiktionary.org/wiki/desenrascan%C3%A7o&#34;&gt;uma palavra&lt;/a&gt; para descrever esta virtude cultural, foi a de imaginar que fugiríamos a estas taxas absurdas comprando o nosso equipamento em lojas &lt;em&gt;online&lt;/em&gt; como é o caso da &lt;a href=&#34;http://www.amazon.co.uk/&#34;&gt;Amazon UK&lt;/a&gt;/&lt;a href=&#34;http://www.amazon.de/&#34;&gt;DE&lt;/a&gt;. Ainda por cima até já têm entrega gratuita para Portugal. Problema resolvido. Belo.&lt;/p&gt;</description>

      <description>&lt;p&gt;Once in a while at SAPO we cross our path with extraordinary people with uncommon ideas and unlimited motivation. Ideas to which we just can’t say no, those with the right amount of usefulness, awesomeness and uniqueness, you know what I’m talking about.&lt;/p&gt;&#xA;&lt;p&gt;The Panoramas SAPO project was one of those moments. When &lt;a href=&#34;https://twitter.com/baiavieira&#34;&gt;Basílio&lt;/a&gt; and &lt;a href=&#34;https://twitter.com/ppinheiro76&#34;&gt;Pedro&lt;/a&gt; came to us and the thought of making a record Tera pixel panoramic photo of Lisbon took shape, we sank our energy and resources into the project and put up an elite team working together in no time.&lt;/p&gt;</description>

      <description>&lt;p&gt;Here’s a story by this guy who enjoys a good hack, crazy for all things tech vintage, who needed a new computer. He wanted a new OSX based system, he decided to build his own. Yes, it’s yet another hackintosh how to guide and yes, it’s me.&lt;/p&gt;&#xA;&lt;p&gt;I have a ton of Appleish gear in my life. You name the device, I probably have it. Call me a fanboy if you need to. From where I stand, I’m just someone with a strong Unix background (never really used anything else since I quit the Amiga back in the 90s), a desktop Linux user since the slackware distro, and a  sucker for great operating systems that help me do my job most efficiently. My most used and important productivity tool is the command line prompt, undoubtedly. About a decade ago, I quit Gnome and my Debian laptop, gave a try to OSX and bought a Powerbook G4 laptop and never looked back ever since.&lt;/p&gt;</description>

      <description>&lt;p&gt;É público e sabido que eu sou um grande tarado por relíquias informáticas. Fui um orgulhoso dono e utilizador obsessivo e compulsivo de uma mão cheia de pérolas que já só fazem parte do imaginário geek da minha geração, e uns quase 30 anos depois continuo a lembrar-me com saudades desses loucos e indiscritíveis tempos. A prova disso é que na mesma sala aonde escrevo este texto estou rodeado de um Commodore 64 e um Commodore Amiga 1200, completamente operacionais (montados e ligados à televisão) e de uma réplica de uma &lt;a href=&#34;http://arrifana.org/blog/2008/05/fazer-uma-maquina-de-arcade/&#34;&gt;Arcade Machine&lt;/a&gt;.&lt;/p&gt;</description>

      <description>&lt;p&gt;Perspectiva.&lt;/p&gt;&#xA;&lt;p&gt;No filme Ratatuille há uma cena deliciosa que eu não me canso de citar em que o Anton Ego diz assim: “- Do you know what you’d like this evening, sir? -Yes, I think I do. After reading a lot of overheated puffery about your new cook, you know what I’m craving? A little perspective. That’s it. I’d like some fresh, clear, well seasoned perspective. Can you suggest a good wine to go with that?”. Retenham esta ideia.&lt;/p&gt;</description>

      <title>Costa Vicentina, Portugal, Quad Bike Ride</title>

      <description>&lt;p&gt;A couple of years ago I bought a quad bike for fun and pleasure to play around the beautiful southwest coast of Portugal, more precisely the Costa Vicentina, near Aljezur where I own a house. Years passed through and between less visits to the southwest, a busier life, kids and other hobbies, I had temporarily forgotten how amazing the experience can be.&lt;/p&gt;&#xA;&lt;p&gt;Recently I bought a goPro camera, great device, and a bunch of accessories to go with it too. So the last weekend I thought it would be a great opportunity to take the quad out of the garage, take a ride around the inaccessible coast roads of Aljezur and show you the breathtaking places most people don’t know about this region and most cars can’t go, like secret desert beaches, natural preserved lakes and other awesome spots.&lt;/p&gt;</description>

      <description>&lt;p&gt;Independentemente da profissão e do percurso das pessoas eu tenho por princípio nutrir uma grande admiração por todos aqueles que conseguem alcançar o sucesso profissional em Portugal. Estas pessoas têm que ser excepcionais a muitos níveis: não só na sua área de especialidade, mas também na determinação, resistência e na garra que têm que ter para conseguirem ultrapassar tantas barreiras.&lt;/p&gt;&#xA;&lt;p&gt;Cheguei à conclusão que Portugal é um dos raros países do mundo que consegue condenar o fracasso e o sucesso ao mesmo tempo, o que é obra. O fracasso é culturalmente marcante e o sucesso é politicamente penalizado. De uma forma ou de outra o indivíduo que sair dos padrões da aceitação económica ou social predominantes deste país vai sempre levar no pêlo.&lt;/p&gt;</description>

      <description>&lt;p&gt;Um homem que não acredita em nada, sem ideias, é uma pessoa sem rumo que pouco poderá fazer por si e que muito menos fará pelos outros. Os jovens deviam ter a ambição de serem pessoas cheias de crenças, mas ao invés constato que a tendência passa muito pelo inverso: as grandes preocupações da actualidade são a consensualidade, a aceitação, o estatuto. Deixem-se dizer-vos o que é que eu penso de pessoas consensuais: são desinteressantes, tipicamente nunca fizeram nada de jeito na vida e aborrecem-me muito, dão-me literalmente sono.&lt;/p&gt;</description>

      <description>&lt;p&gt;Entre tempos livres e pensamentos que me ocorrem, ando há umas semanas a rabiscar uns textos sobre este Portugal aonde habitamos. Fi-lo para minha própria referência, porque gosto e porque acho que a escrita é um excelente instrumento de preservação do que nos vai na alma durante vários contextos da nossa vida.&lt;/p&gt;&#xA;&lt;p&gt;Decidi que vou partilhar este ensaio neste blog por dois motivos. Primeiro porque a ocasião é propícia pois vivemos tempos de contestação e de reflexão como há muito não me recordo, e segundo tenho um genuíno interesse em provocar reacções a algumas destas ideias e pode ser que consiga obter algumas, espero que sim.&lt;/p&gt;</description>

      <description>&lt;p&gt;Dava-se o ano de 1986, mais coisa menos coisa, contas feitas de cabeça, tinha eu uns 14 anos e passava na rádio um programa de características muito invulgares que me agarrava à aparelhagem de som dos meus pais numa obsessão semanal digna de um caso de estudo sobre doenças adolescentes.&lt;/p&gt;&#xA;&lt;p&gt;Todas as semanas, ao Sábado ou ao Domingo à noite, não consigo precisar, passava numa rádio nacional um concurso dedicado aos amantes do famigerado e popular ZX Spectrum. Durante alguns minutos o locutor calava-se e na sua vez ouvia-se o ruído estridente de um programa de ZX Spectrum a passar nas ondas radiofónicas do país. Sim, &lt;a href=&#34;http://www.youtube.com/watch?v=O6uwfM8F5uU&#34;&gt;esta barulheira&lt;/a&gt; era o que qualquer ouvinte teria que suportar se sintonizasse a estação nesse momento.&lt;/p&gt;</description>

      <description>&lt;p&gt;On the 23rd of October, the Spacebits team did something of epic proportions. Thanks to the amazing support and sponsorship of SAPO.PT, we organized an unique event and simultaneously launched 3 high altitude balloons all from one single place.&lt;/p&gt;&#xA;&lt;p&gt;&lt;img src=&#34;https://celso.io/assets/spacebits-flights-3-4-and-5-1.jpg&#34; alt=&#34;NewImage&#34; title=&#34;NewImage&#34;&gt;&lt;/p&gt;&#xA;&lt;p&gt;It took us a few weeks to put everything together. We began by inviting every geek and hacker at SAPO.PT to join the team and work with us to accomplish our mission. The first two weeks were dedicated to a few sessions to explain all our learnings from Spacebits 1 and 2 flights to all our new team members.&lt;/p&gt;</description>

Durante horas falámos de Portugal, dados abertos e visualizações, quer pela perspectiva tecnológica, quer social. Ali nasceu uma ideia de construir um caso prático na Internet de uma visualização dos dados estatísticos de uma área muito importante da nossa sociedade: a justiça.&lt;/p&gt;</description>

      <description>&lt;p&gt;Retrocast is an experiment, a proof of concept, an hack, and nothing else but this.&lt;/p&gt;&#xA;&lt;p&gt;You may have heard of the new gaming platforms like &lt;a href=&#34;http://www.onlive.com/&#34;&gt;OnLive&lt;/a&gt; or &lt;a href=&#34;http://jogos.meo.pt/&#34;&gt;Meo Jogos&lt;/a&gt; (which the company I work for launched recently). They’re a new paradigm in what comes to gaming: you don’t need a console or an expensive PC, you’ll pay a cheap flat fee or renting cost to play the high end games, all the processing power and game rendering is done on the Datacenter and the video is streamed to your house, all in real time. All you need is a thin client to use the service which, in a simplified way, should be able to decode video and send your gamepad commands over the network to the game cloud.&lt;/p&gt;</description>

É impressionante o quão irritante e ensurdecedor aquele barulho consegue ser não só para quem está lá mas também também para os telespectadores. E aparentemente, a julgar pelos inúmeros movimentos anti-vuvuzela que se vêem pelo mundo fora, online e offline, não sou eu que sou esquisito.&lt;/p&gt;&#xA;&lt;p&gt;Ontem, do nada e numa reunião de trabalho sobre temas não relacionados, num piscar de olhos nasceu uma ideia brilhante: e que tal no Meo ter uma opção para desligar a porcaria das Vuvuzelas?&lt;/p&gt;</description>

      <description>&lt;p&gt;Tenho o arquivo de E-mail bem organizado desde o ano 2000, são já 44Gbytes, antes disso infelizmente tenho pouco, ou porque o perdi ou porque está disperso. Este é um exercício que me parece saudável e interessante de fazer no dia 1 de Janeiro de 2010. Baseando-me apenas na minha INBOX e na minha actividade em 2000, qual era a realidade da Internet há exactamente uma década em 10 pontos?&lt;/p&gt;</description>

Satisfação porque correu muito bem e porque nos orgulhamos de ter proporcionado três dias inesquecíveis aos participantes do evento, mas também tristeza porque o que é bom não devia acabar assim tão bruscamente, parece que morreu alguém. Este evento provoca-nos a todos uma espécie de distúrbio bipolar a oscilar entre a hiperactividade criativa e satisfação extrema, e uma quase depressão nostálgica que é estranha, porque só acabou ontem mas parece que foi há mais tempo, porque já temos saudades.&lt;/p&gt;</description>

      <description>&lt;p&gt;Impressiona-me como é que os organismos públicos e os seus representantes gastam tanta energia com a discussão, com a análise, com o debate político no fundo em vez de canalizarem esses recursos todos, essa vitalidade, para a execução. Hoje com 36 anos eu já entendo, com alguma dificuldade é certo, que a política é menos um programa de computador e mais um jogo de poker. Há analistas em excesso e executivos em défice. Em Portugal ser político é assim mais ou menos como se um jogador de futebol tivesse a obrigação profissional de comentar os seus próprios jogos para além de maximizar o seu rendimento físico para marcar golos.&lt;/p&gt;</description>

      <description>&lt;p&gt;Inadvertidamente descobri uma pequena API do Facebook, utilizada no wizard de estimativas de publicidade do serviço que permite fazer todo o tipo de queries demográficos à base de dados de utilizadores do Facebook. Decidi queimar 1 hora e fazer um script para extrair os dados. Eis as estatísticas para Portugal:&lt;/p&gt;&#xA;&lt;div class=&#34;highlight&#34;&gt;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;&#34;&gt;&lt;code class=&#34;language-fallback&#34; data-lang=&#34;fallback&#34;&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span&gt;Total Portuguese users: 188500&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span&gt;Total male users: 88000&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span&gt;Total female users: 95900&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span&gt;Total users from 0-20y: 27380&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span&gt;Total users from 21-30y: 89160&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span&gt;Total users from 31-40y: 49760&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span&gt;Total users with +41y: 24120&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span&gt;Total female users interested in males: 560&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span&gt;Total male users interested in females: 2740&#xA;&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;&lt;strong&gt;Update&lt;/strong&gt;, e já agora as mesmas stats para Espanha:&lt;/p&gt;</description>

Lidar eficazmente com problemas e com pessoas, ou melhor, com pessoas com problemas é um desafio e peras.&lt;/p&gt;&#xA;&lt;p&gt;Se há equipas que eu respeito são aquelas que se matam por um melhor atendimento e por um melhor suporte aos nossos clientes ou utilizadores. Depois do produto, a nossa ajuda e o nosso apoio são sem sombra para dúvida o segundo factor mais distintivo que podemos ter nos nossos serviços, para o bem e para o mal.&lt;/p&gt;</description>

Quem é que se lembra dos tempos da Fidonet, &lt;a href=&#34;http://twitter.com/celso/status/1095831247&#34;&gt;perguntei eu no Twitter&lt;/a&gt; há pouco. É uma boa pergunta para percebermos a nossa ciber-idade, ou o nosso ciber-calo como eu prefiro pensar. Saltaram estes da cartola assim de repente:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Eu: 2:361/9 (Biosmática)&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&#34;http://twitter.com/rubikoO/statuses/1095849858&#34;&gt;Fausto Carvalho&lt;/a&gt;: 2:361/1 (Midi-thru)&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&#34;http://twitter.com/mvalente/statuses/1095900741&#34;&gt;Mário Valente&lt;/a&gt;: 2:362/4 (via Bat, do Paulo Laureano)&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&#34;http://twitter.com/agil/statuses/1095907056&#34;&gt;António Matias&lt;/a&gt; Gil 2:362/31&lt;/li&gt;&#xA;&lt;li&gt;&lt;a href=&#34;http://twitter.com/vonfreud/statuses/1095915962&#34;&gt;Frederico Marques&lt;/a&gt; 2:36x/y&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;Mas há mais que eu sei, mostrai-vos. Aliás, &lt;a href=&#34;http://labs.sapo.pt/ua/cfausto/&#34;&gt;Fausto&lt;/a&gt;, devias fazer um &lt;em&gt;post&lt;/em&gt; com a história bem contada porque eu na altura era aprendiz.&lt;/p&gt;</description>

      <description>&lt;p&gt;Há umas semanas fez-se uma reunião histórica lá no trabalho, a primeira de uma série de tantas para começar a preparar um evento que na minha opinião entrará directo para a história dos momentos SAPO: a transmissão de um jogo de futebol importante ao vivo na Internet, neste caso o Benfica/Nápoles. A oportunidade fez parte de um pacote mais abrangente que incluiu o lançamento do canal Benfica, que como sabem é um exclusivo do Meo, com a sua primeira emissão ao vivo.&lt;/p&gt;</description>

      <description>&lt;p&gt;Antes de ir de Férias, o Sr. Nelson Marques, Jornalista e colaborador do Expresso, pediu-me uma opinião sobre “um artigo sobre o Google (e, no fundo, a Internet) e a forma como ele tem alterado, por exemplo, a forma como lemos e percepcionamos esta informação.” a propósito de um recente &lt;a href=&#34;http://celso.arrifana.org/archives/456-Sobre-a-atenco.html&#34;&gt;“post” neste Blog&lt;/a&gt;. Acedi responder. Era uma tema “quente” e que me interessava e portanto gastei algum tempo com a resposta para que ficasse claro o meu ponto de vista. Este fim de semana comecei a receber SMSes de amigos por causa do meu nome ter aparecido associado a um artigo do Expresso intitulado “&lt;a href=&#34;http://aeiou.expresso.pt/gen.pl?p=stories&amp;amp;op=view&amp;amp;fokey=ex.stories/397363&#34;&gt;Está o Google a tornar-nos estúpidos?&lt;/a&gt;“.&lt;/p&gt;</description>

      <description>&lt;p&gt;Quem roçar na minha geração sabe o que é um salão de máquinas de &lt;em&gt;arcade&lt;/em&gt;. Sabe, se for uma pessoa normal e dentro do &lt;em&gt;target&lt;/em&gt; deste blog, certamente, como é passar intervalos ou uma tarde livre de aulas (ou não) fechado num salão agarrado a um &lt;a href=&#34;http://en.wikipedia.org/wiki/Bubble_Bobble&#34;&gt;Bubble Bobble&lt;/a&gt;, &lt;a href=&#34;http://en.wikipedia.org/wiki/Shinobi_%2528arcade_game%2529&#34;&gt;Shinobi&lt;/a&gt;, &lt;a href=&#34;http://en.wikipedia.org/wiki/New_Zealand_Story&#34;&gt;New Zealand Story&lt;/a&gt; ou &lt;a href=&#34;http://en.wikipedia.org/wiki/Rainbow_Islands&#34;&gt;Rainbow Islands&lt;/a&gt;, só para mencionar alguns. Sabe o que é ser expulso dos salões por ainda não ter idade para os frequentar, sabe o que é poupar no lanche para gastar na jogatana, sabe jogar snooker e setas, sabe truques e maroscas e enganar o responsável do salão de jogos e sabe, acima de tudo, escrever o nome completo com apenas 3 letras e com orgulho.&lt;/p&gt;</description>

Não tem interesse porque todas as pessoas neste País têm um telemóvel (ou vários) e estão permanentemente ligados, a maior parte durante a noite inclusive. Os portugueses estão permanentemente disponíveis com o telemóvel, é seguro dizer. E portanto colocar uma aplicação de IM no telefone acrescenta o quê em relação ao SMS que é praticamente gratuito e que possivelmente funciona na mais bem trabalhada aplicação nativa que qualquer aparelho pode trazer? Informação de presença não é. Nada, não há absolutamente nada de relevante no IM no telemóvel a não ser uma ligeira sensação efémere de que estamos na crista da onda a falar com os amigos do PC num teclado de 9 teclas. E então quando me falavam de tarifários a cobrar à mensagem…&lt;/p&gt;</description>

So after a lot of testing and fiddling I think I finally settled with a nice setup which works for me. This post will try to describe it, in English just because the target audience is broader.&lt;/p&gt;&#xA;&lt;p&gt;First of all a few notes.&lt;/p&gt;</description>

      <description>&lt;p&gt;Ok, alguém me vai matar por isto amanhã. Mas estive a ponderar e sinto que há legitimidade para tornar este vídeo público: Primeiro porque tenho créditos, muitos créditos, no que diz respeito a expor situações embaraçosas dos meus queridos colegas e amigos de trabalho. Segundo porque já lá vão mais de 4 anos, e todos sabem que na Internet 4 anos são na realidade 12, é muito tempo.&lt;/p&gt;&#xA;&lt;p&gt;Este vídeo representa um marco na cultura interna do SAPO. Foi o nosso primeiro mega-projecto, que envolveu tempo, recursos e custos consideráveis para essa altura. Tratou-se de construir a nova plataforma  toda baseada em produtos Opensouce (ie: Qmail, Horde, Debian Linux, etc, etc.) e que viria a suportar o E-Mail da Telepac e do próprio SAPO, e que ainda hoje existe.&lt;/p&gt;</description>

Thanks all for your feedback, we’re proud. My friend Pedro was crazy and kind enough to &lt;a href=&#34;http://pfig.livejournal.com/208601.html&#34;&gt;translate the post to english&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;Ontem lançámos o &lt;a href=&#34;http://sapo.cv/&#34;&gt;SAPO Cabo Verde&lt;/a&gt;. A sensação de ter um SAPO fora de Portugal é no mínimo estranha, é um misto de orgulho e de medo, em que a segunda das sensações advém certamente do facto de nunca termos pensado muito nisto, na hipótese de actuarmos fora do rectângulo. É o tal síndroma que nos persegue, aos Portugueses em geral, para aí desde o tempo em que deixámos de pensar que somos grandes.&#xA;O projecto já cozinhava há uns largos meses. Não vou aqui discutir nem as razões nem os objectivos, alguém o fará por mim, vou só falar de tecnologia. Tecnologicamente falando, instanciar o SAPO fora de Picoas foi um desafio muito interessante. Uma coisa é escalarmos dentro do mesmo Datacenter mas outra coisa é sair do útero, distribuir conteúdos em pontos do globo distintos e distantes e reutilizar a mesma tecnologia mas em contextos diferentes e com características diferentes da nossa realidade mantendo ao mesmo tempo uma arquitectura global.&lt;/p&gt;</description>

O meu dia a dia agora é conseguir fazer uma balança o mais eficaz e inteligente possível entre o que esperam de mim e o que eu espero de mim mesmo. Não me queixo, dá-me gozo, mas não é fácil. Também se fosse… Já lá vão os dias em que a gestão do meu tempo e das minhas prioridades era feita sem o auxílio de ferramentas, tranquilamente. Hoje não dá mesmo.&lt;/p&gt;</description>

This is how I got it working. Not that it’s hard, but here it is in writing to avoid common pitfalls (talk about niche posts).&lt;/p&gt;&#xA;&lt;p&gt;Note 1: I have no experience with Actionscript, Flash or Flex.&lt;/p&gt;</description>

Tendo em conta que a pressão e a concorrência global aumentaram significativamente em 2007, e que manter a nossa posição custa e dá trabalho ‘pra caraças, isto é sempre agradável. Na volta saltamos fora na versão final. Let’s hope not, 5 dias até lá.&lt;/p&gt;</description>

Quando acrescentamos perspectiva a dados aparentemente unidimensionais, seja através de um vídeo ou de uma imagem, ou de som, ou quando da mesma forma correlacionamos duas fontes de informação e lhes damos “vida” então criamos uma obra de arte. E a arte é conseguir surpreender o espectador com uma representação impensável e espectacular daquilo que para nós não passam de dados crus, logfiles, eventos isolados, database dumps, &amp;ldquo;terminal stuff&amp;rdquo;.&lt;/p&gt;</description>

Ah sim, ficou nos vintes, juntamente com a força de fazer directas a trabalhar e fazer jantaradas com os amigos no fim dos projectos, quando ainda tinha inocência suficiente para pensar que ia mudar o mundo.

Espero contribuir com alguma informação e lucidez, mesmo que em alguns pontos seja apenas a minha opinião, que vale o que vale, claro seja.A televisão digital terreste (TDT, ou DTT) é uma uma plataforma de difusão digital do sinal de televisão e vai substituir as actuais emissões analógicas. Algumas das vantagens mais claras e directas para o consumidor são uma melhor qualidade da imagem e de serviço, a possibilidade de ter canais em HD, mais canais, dispensa a antena no telhado (o equipamento terminal e receptor pode estar todo dentro de casa, até pode ser uma &lt;a href=&#34;http://www.elgato.com/elgato/int/mainmenu/products/tuner/DTT/product1.en.html&#34;&gt;coisa destas&lt;/a&gt;).Mas a DTT é também, e acima de tudo, um passo gigante no que diz respeito a aproveitar melhor os recursos radioeléctricos, vulgo espectro, uma vez que é possível ter mais canais de televisão e com mais qualidade, utilizando menos gamas de frequências do que a plataforma analógica. Com esta transição vai-se libertar muito espectro. Estas frequências que vão ficar livres são muito valiosas porque são “premium”, têm muita capacidade de propagação e conseguem entrar bem dentro das casas e dos edifícios. Mais sobre isto à frente.O switch-off da televisão analógica em Portugal e na Europa &lt;a href=&#34;http://www.anacom.pt/template12.jsp?categoryId=251646&#34;&gt;está previsto para 2012&lt;/a&gt;, 3 anos depois dos E.U.A. A data foi estabelecida pela comissão Europeia para todos os países membros. Até lá terá que ocorrer a transição para digital em que se prevê também um periodo de adaptação dos consumidores às novas ofertas de TDT Freeview ou pagas (ie: aquisição de setop boxes  ou aparelhos adaptadores, &lt;a href=&#34;https://www.dtv2009.gov/&#34;&gt;começou agora&lt;/a&gt; nos E.U.A.). &lt;/p&gt;</description>

Eu trabalho na PT.COM, a empresa do &lt;a href=&#34;http://sapo.pt/&#34;&gt;SAPO&lt;/a&gt; e que pertence ao grupo &lt;a href=&#34;http://www.telecom.pt/&#34;&gt;Portugal Telecom&lt;/a&gt;. Este é um post sobre tecnologia. Quem achar que isto é publicidade, ou quiser fazer deste post um pretexto para desabafar sobre as políticas da banda larga em Portugal, ou desatinar em geral, por favor faça-me já um favor e rume a outras paragens.&lt;/p&gt;&#xA;&lt;p&gt;Esclareço também que o post anterior não tem assim tanto de enigmático para os mais atentos. Simplesmente entrei nos testes de &lt;a href=&#34;http://en.wikipedia.org/wiki/FTTH&#34;&gt;FTTH&lt;/a&gt; (Fiber to the home) que estão a ser feitos pela PT Comunicações na zona da Expo (e em Miraflores também, salvo erro).

      <description>&lt;p&gt;Back in the Tiger days, Quartz Composer had few support for network sources. The &lt;a href=&#34;http://developer.apple.com/documentation/GraphicsImaging/Conceptual/QuartzComposerUserGuide/qc_editor/chapter_3_section_3.html&#34;&gt;RSS feed&lt;/a&gt; patch was pretty much the only way we had to read data from the net, but it was way too limited (no streaming, not event based, not extendable, no input or output triggers).&lt;/p&gt;&#xA;&lt;p&gt;I needed a way to get data from the Network in the form of events that I could reuse in a quartz composition. So our resident mac programmer coded &lt;a href=&#34;http://trac.softwarelivre.sapo.pt/broker/wiki/qtzplugin&#34;&gt;this custom made patch&lt;/a&gt; based on sparse non official documentation found on the internet. And it worked great. We have about 5 plasma screens with mac minis over at work running it for months, no problems whatsoever.&lt;/p&gt;</description>

      <description>&lt;p&gt;Bom, acho que já recuperei. O Codebits terminou e os dias que se seguiram foram de embriaguez daquela de missão cumprida e de sucesso. Tantos E-Mails, SMSes e telefonemas que recebemos. Muito agradável. Em 12 anos ligado ao projecto SAPO, o Codebits foi para o topo dos marcos históricos das iniciativas que nos orgulhamos muito e que sabemos que mudam o nosso rumo.&lt;/p&gt;&#xA;&lt;p&gt;Foi acima das minhas próprias expectativas, e quem me conhece sabe que eu sou optimista por natureza.&lt;/p&gt;</description>

      <description>&lt;p&gt;I’m a huge fan of Amazon. The way they turned just a successful book selling platform into one of the coolest internet companies and teams in the world, fighting head to head with Google, Yahoo and MS in the innovation and services playground is nothing to disdain. If you’re a geek, you’ll know Amazon better from &lt;a href=&#34;http://aws.amazon.com&#34;&gt;AWS&lt;/a&gt;, &lt;a href=&#34;https://payments.amazon.com/sdui/sdui/index.htm&#34;&gt;FPS&lt;/a&gt;, &lt;a href=&#34;aws.amazon.com/ec2&#34;&gt;EC2&lt;/a&gt; and &lt;a href=&#34;aws.amazon.com/s3&#34;&gt;S3&lt;/a&gt; than, hum.. &lt;a href=&#34;http://amazon.com/&#34;&gt;books&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;I really think Amazon has a great vision of what the future of computing resources will be, and they’re shaping it, silently and cleverly.&lt;/p&gt;</description>

      <description>&lt;p&gt;Ao tornarem-se páginas web em aplicações assíncronas, perde-se a tradicional noção de actividade através animação do browser (vulgo “E” do IE a rodar, ou spinwheel no Safari, ou o que quer que o tema do Firefox tenha).&lt;/p&gt;&#xA;&lt;p&gt;Assim sendo, com o advento do Ajax, chegou também a praga das &lt;a href=&#34;http://www.napyfab.com/ajax-indicators/&#34;&gt;spin-wheels&lt;/a&gt; nas páginas. Foi a resposta óbvia, com  inspiração gráfica no Safari, para o problema da falta de feedback que o UI deixou de dar ao utilizador quando a página está a “carregar”. E de certa forma tornou-se numa norma para os sites modernos.&lt;/p&gt;</description>

      <description>&lt;p&gt;Que dia é hoje ? Não interessa, mas é um bom dia. É o dia em que um dos mais fascinantes projectos do SAPO dos últimos tempos deu à luz, só para usar a &lt;a href=&#34;http://blog.pdvel.com/2007/10/10/as-fotos-do-bebe/&#34;&gt;metáfora do papá&lt;/a&gt;.&lt;/p&gt;&#xA;&lt;p&gt;&lt;a href=&#34;http://messenger.sapo.pt/im/&#34;&gt;O bicho&lt;/a&gt; está mesmo bem feito. E acreditem que não foi fácil. Esta obra de engenharia  funciona como um relógio suíço em Firefox, Safari, IE6/7 e Opera. Até funciona no Safari do iMighty vejam lá bem, dizem por aí.&lt;/p&gt;</description>

      <description>&lt;p&gt;&lt;a href=&#34;https://celso.io/uploads/IMG_0058.JPG&#34;&gt;&lt;img src=&#34;https://celso.io/assets/mediamarkt-does-it-again-1.jpg&#34; alt=&#34;&#34; title=&#34;photo 1&#34;&gt;&lt;/a&gt;&lt;/p&gt;&#xA;&lt;p&gt;Há muito tempo atrás deixei aqui uma &lt;a href=&#34;https://celso.io/archives/60-O-VoIP-da-Luz.html&#34;&gt;pérola da Mediamarkt&lt;/a&gt;. Há uns dias fui lá novamente comprar já não sei bem o quê, e dei com outra que merece destaque.&lt;/p&gt;&#xA;&lt;p&gt;Ponto um, não é “a Sapo”, é “o SAPO”. Tudo bem que o batráquio dos anúncios não tem pilinha mas mesmo assim, e a julgar pela quantidade de modelos que atrai, parece-me macho o suficiente.&lt;/p&gt;&#xA;&lt;p&gt;Ponto dois, desde quando é que o SAPO vende embalagens com créditos de Skype?&lt;/p&gt;</description>

      <title>O que mais me irrita</title>

      <description>&lt;p&gt;Há muitas coisas que me irritam. Agora que sou Pai e que tenho muito menos tempo para humm desperdícios de tempo, tornei-me  mais objectivo e menos tolerante, ou numa palavra só, tornei-me um chato. Poderia falar de irritações banais, daquelas que temos na ponta da língua, do fumo nos locais públicos e da não lei do tabaco que o governo (não) aprovou, ou do barulho dos sacos de plástico dos supermercados, ou da falta de senso de humor das pessoas, etc, etc., mas não.&lt;/p&gt;</description>

      <description>&lt;p&gt;Finalmente. Após muitas semanas de preparação e o envolvimento e empenho de muitas pessoas eis que por fim estamos em condições de confirmar e divulgar o primeiro evento do SAPO completamente dedicado a programadores, hackers e webdesigners, ou genericamente falando talento de Internet em Portugal.&lt;/p&gt;&#xA;&lt;p&gt;A inspiração no formato do Yahoo! Hackday é óbvia e é justo referi-la. O conceito apaixonou-nos desde &lt;a href=&#34;http://celso.arrifana.org/archives/185-eTech-2007-Session-Hacking-Yahoo.html&#34;&gt;o primeiro dia&lt;/a&gt; e tem tudo a ver connosco, e portanto tornou-se claro que iríamos fazer o possível e o impossível para tornar o sonho numa realidade. &lt;a href=&#34;http://codebits.sapo.pt/&#34;&gt;E cá está&lt;/a&gt;.&lt;/p&gt;</description>

      <description>&lt;p&gt;Já só faltava eu falar sobre planetas.&lt;/p&gt;&#xA;&lt;p&gt;Nunca os percebi. O meu agregador é o meu leitor de RSS e o meu planeta é a soma das minhas subscrições individuais. Claramente algo me estava a escapar (1).&lt;/p&gt;&#xA;&lt;p&gt;Nos últimos tempos tenho falado com diversas pessoas sobre a utilidade e as mais valias dos agregadores públicos. Até aceitei um convite antigo e persistente para integrar um. Mas por muitas experiências que faça para tentar compreender o fenómeno aparente da popularidade dos mesmos, as minhas interrogações e as minhas convicções permanecem. Vejam comigo:&lt;/p&gt;</description>

      <description>&lt;p&gt;&amp;hellip;that most people don’t mention.&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&#xA;&lt;p&gt;It has no fr&lt;em&gt;ak&lt;/em&gt;ng 801.2X support. This means no corporate Wifi and in no transparent authentication in some public Wifi networks.&lt;/p&gt;&#xA;&lt;/li&gt;&#xA;&lt;li&gt;&#xA;&lt;p&gt;Again public Wifi networks. I think Apple should look into this carefully because it’s all about ease of use and commodity. What’s the point on having a gorgeous transition between GPRS/EDGE and Wifi if I’ll be stuck in a crippled Hotspot HTML page to logon ? The Wifi alliance has some recommendations for smart clients (using meta information on the hotstop webpages) to automate the authentication process. You should look into this.&lt;/p&gt;</description>

      <description>&lt;p&gt;Nesta altura fico sempre lamechas e meio estúpido mas a nostalgia faz parte da minha natureza, é difícil de evitar. Há 12 anos atrás eu, o Júnior, o João Luís, o Hélder, o Sérgio e o Fernando tivemos a brilhante ideia, sabemos hoje, de dar o pontapé de saída no batráquio na Universidade de Aveiro. Desde 1995 que eu não faço (quase) mais nada senão ajudar a tocar isto para a frente. Parece triste não é ? Mas não.&lt;/p&gt;</description>

      <description>&lt;p&gt;Courage, persistence and hard-work will always make the impossible, possible. Took me about 6h30m hours of unprecedentedly (nano)hardware fiddling, with soldering skills I wasn’t aware I had (no needles, that sucked too), but fuck, I did it. &lt;a href=&#34;http://iphonejtag.blogspot.com/&#34;&gt;Geohot&lt;/a&gt;‘s method, fully unlocked, not the silvercard/supersim crap. Works. &lt;a href=&#34;http://fotos.sapo.pt/celso/gallery/0000b6zx&#34;&gt;Check the gallery&lt;/a&gt;. off to bed now.&lt;/p&gt;</description>

      <description>&lt;p&gt;&lt;a href=&#34;http://iphonejtag.blogspot.com/&#34;&gt;Geohot’s accomplishment&lt;/a&gt; is all over the web my now so I won’t comment on it any further but this &lt;a href=&#34;http://video.msn.com/v/us/fv/msnbc/fv.htm??f=00&amp;amp;g=1a2244ba-ba39-4440-9ea3-88a72c43fbba&amp;amp;p=source_cnbc&amp;amp;t=m5&amp;amp;rf=http://www.msnbc.msn.com/id/20424880/&amp;amp;fg=&#34;&gt;MSNBC live interview with him&lt;/a&gt; is worth watching. George is an remarkable hardware guy but above all, it’s his motivation and his ethics that are worth mentioning. He’s a true hacker.&lt;/p&gt;&#xA;&lt;p&gt;I and a few friends actually followed the whole story on IRC live, when he wrote the step-by-step tutorial on the Blog. In fact, we were so intoxicated with the story, that we decided to do an unlocking marathon later at my place. The result was a disaster, do not attempt to do this unless you’re a soldering expert, really (see &lt;a href=&#34;http://iphone.unlock.no/tiny.jpg&#34;&gt;this pic&lt;/a&gt; for a good idea on the size of these circuit tracks). I’ve modded a few consoles in the past and I was very confident but what I saw was insane. And by the way opening the iPhone wasn’t  easy too. So we were stuck in step 3 and wen’t back to the drawing board. Idiots. We have a video of this, I’ll edit it and post it soon, for your amusement.&lt;/p&gt;</description>

      <description>&lt;p&gt;Ok guys this is warning. Lots of iPhone related posts will follow. I know it’s sick and you’re not interested but there’s just too much fun going on here, sorry. This is your chance to unsubscribe this feed or drop this blog.&lt;/p&gt;&#xA;&lt;p&gt;This post is dedicated to João Pavão and João Pedro. These two (&lt;a href=&#34;http://celso.arrifana.org/iphone/imgs/DSC00225.JPG&#34;&gt;img1&lt;/a&gt;, &lt;a href=&#34;http://celso.arrifana.org/iphone/imgs/DSC00226.JPG&#34;&gt;img2&lt;/a&gt;) images are self-explanatory. :p&lt;/p&gt;&#xA;&lt;p&gt;Two nights struggling with pre-alpha software, sparse docs and a couple of problems due to my “non 10.4/10.3 environment”, and I finally managed to get the iPhone toolchain, cross-compiler and frameworks working, after which compiling “my” &lt;a href=&#34;http://iphone.fiveforty.net/wiki/index.php/UIKit_Hello_World&#34;&gt;first native application&lt;/a&gt; for the iPhone was easy.&lt;/p&gt;</description>

      <title>iPhone, PT-WIFI and rfc2397 fun</title>

      <description>&lt;p&gt;I told you &lt;a href=&#34;https://celso.io/blog/2007/08/rfc2397-and-the-iphone/&#34;&gt;rfc2397 was good&lt;/a&gt; for offline storage didn’t I ? &lt;a href=&#34;https://celso.io/iphone/ptwifi&#34;&gt;Here’s a program&lt;/a&gt; (&lt;a href=&#34;http://arrifana.org/iphone/ptwifi/?showsource=1&#34;&gt;source&lt;/a&gt;) that generates two bookmarks. Each of those are actually javascript programs customized with your &lt;a href=&#34;http://www.ptwifi.pt/default.aspx?selectedCulture=en&#34;&gt;PT-WIFI&lt;/a&gt; credentials.&lt;/p&gt;&#xA;&lt;p&gt;Bottom line, you can save these bookmarks on your iPhone’s Safari browser and once you have PT-WIFI coverage you’re one-click away to instant log on. No more clumsy, painful web redirects or forms to fill in. Very handy.&lt;/p&gt;&#xA;&lt;p&gt;Once you get the idea, you can make your own version for your local WIFI operator.&lt;/p&gt;</description>

      <description>&lt;p&gt;I just joined the club of those in Portugal who have an iPhone and can actually talk about it, sort of.&lt;/p&gt;&#xA;&lt;p&gt;This is not a review, I’m tired of pointless opinions about the device. No matter how many defects you find, this toy is truly amazing stuff, specially the software and the OSX foundations.&lt;/p&gt;&#xA;&lt;p&gt;STILL, the one only thing that really pisses me off is that it does not support 802.1X. So for now, forget about seamless authentication on many WIFI networks, including some public nationwide soon-to-have ones. I really hate having to go through those webpage redirects to get logged in.&lt;/p&gt;</description>

And it’s not for the faint of heart. I’ve lost the status of this effort with our &lt;a href=&#34;http://blog.pdvel.com/&#34;&gt;js guru&lt;/a&gt; but I know we all wished IE7 supported data:.

      <description>&lt;p&gt;If you live in Germany, from today on you might just &lt;a href=&#34;http://www.makezine.com/blog/archive/2007/08/the_hacker_tool_law_in_ef.html?CMP=OTC-0D6B48984890&#34;&gt;get arrested for making an Hacker Tool&lt;/a&gt;. And pretty much anything call fall into this category, even “ping -f” functionality could get ping’s author into trouble. Amazing.&lt;/p&gt;&#xA;&lt;p&gt;But don’t get too amazed, in Portugal a very similar law was introduced recently. It came and was approved so smoothly and so under the radar that it makes me think about the whole law approval process in Portugal, the lobbyists,  and how people are disconnected and uninterested in politics. Or at least until they take on our basic liberty principles, like this is the case, &lt;a href=&#34;http://blog.softwarelivre.sapo.pt/2007/07/31/diz-nao-ao-ooxml-13/&#34;&gt;but then it’s too late&lt;/a&gt;. And that’s generally the point when Portuguese complaint, like me.&lt;/p&gt;</description>

      <description>&lt;p&gt;O senhor &lt;a href=&#34;mailto:jramos.pt&#34;&gt;João Ramos&lt;/a&gt; publicou este fim de semana uma peça no suplemento de economia do Expresso intitulada “Nokia com novo fôlego”. Ora eu coloco a Nokia no topo das empresas que inovam e surpreendem (e ainda por cima suportam o Opensource) e também não tenho nada contra as peças encomendadas nos jornais – é prática comum e já ultrapassei a fase do purismo, mas acho ao mesmo tempo que o jornalismo de especialidade deveria algum mais cuidado com o rigor da matéria que escrevem.&lt;/p&gt;</description>

      <description>&lt;p&gt;Quando &lt;a href=&#34;http://campusparty.aeiou.pt/&#34;&gt;tudo parecia perdido&lt;/a&gt; eis que de repente se dá um milagre e em semana e meia se vai tentar recuperar a &lt;a href=&#34;http://bragacampusparty.dsi.uminho.pt/&#34;&gt;Campus Party&lt;/a&gt; mais histórica de .pt. Suddenly &lt;a href=&#34;http://bragacampusparty.dsi.uminho.pt/main.php&#34;&gt;powered by SAPO/PT&lt;/a&gt;. Ajudai-nos :p&lt;/p&gt;&#xA;&lt;p&gt;&lt;strong&gt;update&lt;/strong&gt;: “Caros amigos:&lt;/p&gt;&#xA;&lt;p&gt;Infelizmente não vai ser possível realizar o BragaCampusParty, previsto para os próximos dias 25 a 29 de Julho. Conseguiram-se alinhar as vontades institucionais necessárias, incluindo os apoios da PT e do Sapo, cujo empenhamento era naturalmente auspicioso. As questões das redes físicas estavam também asseguradas em tempo útil. Mas durante o dia de hoje (terça feira) criou-se uma situação que tornou inviável a logística de realização do evento. Com um planeamento quase sem folga, um contratempo logístico tornou-se rapidamente inultrapassável. Fica assim comprometido o esforço de recuperar para Braga um evento deste tipo, aproveitando a disponibilidade do material da Cisco que estava previsto para a Batalha.&lt;/p&gt;</description>

This is just a quick note to say that &lt;a href=&#34;http://www.bbc.co.uk/&#34;&gt;BBC&lt;/a&gt; and Y! rocked. We had loads of fun and learned a lot too.&lt;/p&gt;&#xA;&lt;p&gt;The &lt;a href=&#34;http://hackday.sig9.net/&#34;&gt;hack that we submitted&lt;/a&gt; didn’t won any prize, so we were clearly robbed there (maybe if the timer guy hadn’t shut us down during our presentation, bah…) but still a very big thumbs up to anyone &lt;a href=&#34;http://icant.co.uk/webstandardsforbusiness/pmwiki.php/main/HackDay&#34;&gt;on the list&lt;/a&gt;, to the jury, &lt;a href=&#34;http://developer.yahoo.net/hackday/2007/06/the_hack_day_london_winners_li.html&#34;&gt;the winners&lt;/a&gt;, and to &lt;a href=&#34;http://www.flickr.com/photos/37354253/564494434&#34;&gt;ourselves too&lt;/a&gt;. .pt rules.&lt;/p&gt;</description>

      <description>&lt;p&gt;Bought the &lt;a href=&#34;http://www.amazon.com/iWoz-Computer-Invented-Personal-Co-Founded/dp/0393061434&#34;&gt;iWoz book&lt;/a&gt; in London last weekend and read it all during my trip to Seattle (more on this later, I promise). The book is sort of a biography from &lt;a href=&#34;http://en.wikipedia.org/wiki/Steve_Wozniak&#34;&gt;Steve Wozniak&lt;/a&gt;, his relationships and life, entrepreneurship, and a big emphasis on the &lt;a href=&#34;http://en.wikipedia.org/wiki/Apple_I&#34;&gt;Apple I&lt;/a&gt; and the &lt;a href=&#34;http://apple.com/&#34;&gt;Apple&lt;/a&gt; creation.&lt;/p&gt;&#xA;&lt;p&gt;The book is as easy reading as it gets, and because of the simple and sincere way Woz exposes his personal fears and secrets it’s really passionate reading for geeks of all ages. Plus it has so many parallels and similarities with myself and my still young career and life and what I went through, yes, including the &lt;a href=&#34;http://en.wikipedia.org/wiki/Phreaking&#34;&gt;Phone phreaking&lt;/a&gt; part, if that’s what you’re wondering.&lt;/p&gt;</description>

      <description>&lt;p&gt;Eu confesso que sou pro-”qualquer um que em vez de se lamuriar meta mãos à obra” mesmo que o dito cujo acerte ao lado uma vez ou outra. O saldo dos determinados é sempre a média dos seus sucessos e insucessos, e normalmente é sempre positivo, é sempre melhor do que reclamar e nenhum fazer.&lt;/p&gt;&#xA;&lt;p&gt;E é por isso que não sou de políticas. Mesmo sendo deformado por uma educação mais à direita do que à esquerda (seja lá o que isso for), é com a maior das naturalidades que entre amigos tenho elogiado uma série de medidas do actual governo e de alguns ministros que têm tido a coragem de executar decisões difíceis e impopulares nas mais diversas áreas da nossa sociedade.&lt;/p&gt;</description>

      <description>&lt;p&gt;Today, a particularly stressful day at work, a came across several E-Mail and IM threads about &lt;a href=&#34;http://code.google.com/apis/gears/index.html&#34;&gt;Google Gears&lt;/a&gt; with my friends and colleagues. I finally had the time to look into it more seriously and I feel I should point out that I don’t share the global excitement everyone seems to suffer from.&lt;/p&gt;&#xA;&lt;p&gt;Google Gears anticipates what &lt;a href=&#34;http://www.readwriteweb.com/archives/firefox_3_offline_apps.php&#34;&gt;browsers should have already&lt;/a&gt; and clones what &lt;a href=&#34;http://www.zimbra.com/blog/archives/2006/11/taking_zimbra_offline.html&#34;&gt;Zimbra envisioned months ago&lt;/a&gt;, I fail to understand the wow effect, really. I had that wow when Zimbra &lt;a href=&#34;http://celso.arrifana.org/2007/03/29/etech-2007-ajax-unplugged/&#34;&gt;demoed the concept over at eTech 2007&lt;/a&gt;. Sure, it’s Opensource, and works with almost all platform combinations, and I’m not saying it isn’t neat either, but stop the presses please,  what about these questions ?&lt;/p&gt;</description>

      <description>&lt;p&gt;This is worth a note. After almost two years of development we’re finally gone public with our &lt;a href=&#34;http://messenger.sapo.pt/artigos/725940/mac&#34;&gt;SAPO Messenger for Mac&lt;/a&gt; and are going high-profile on it. It’s been one of the must fun projects on the company, much to be learned from it (a making-of story is a must on this one, I’m convincing João, Pedro and the rest of the crowd to make one). The &lt;a href=&#34;http://trac.softwarelivre.sapo.pt/sapo_msg_mac/&#34;&gt;project is also Opensourced&lt;/a&gt;, also one of the biggest commitments and investments we’ve made with the community so far. So enjoy, we did.&lt;/p&gt;</description>

      <description>&lt;p&gt;Everybody knows Yahoo is doing it’s &lt;a href=&#34;http://hackday.org/&#34;&gt;European version of Hackday in London&lt;/a&gt; in early June. I’ve seen Yahoo’s &lt;a href=&#34;http://celso.arrifana.org/2007/03/29/etech-2007-session-hacking-yahoo/&#34;&gt;presentation&lt;/a&gt; about the US version on eTech and it clicked on me. It’s a great idea for a variety of reasons: Team and company morale boost, tell the outside world what you have, image building amongst the developers community, a great way to find new talent and eventually recruit some, a free test-bed for your infra-structure and APIs, and a great environment for new ideas. And of course not less important, it’s a lot of fun for everybody too, it’s win-win.&lt;/p&gt;</description>

      <description>&lt;p&gt;So don’t ask how (or why) but I got my hands on the &lt;a href=&#34;http://www.apple.com/appletv/&#34;&gt;Apple TV&lt;/a&gt; for a week now. Much has been said about this cute living room apple fruit, but maybe the hacker’s perspective hasn’t gone into much analysis yet. &lt;strong&gt;Hacking&lt;/strong&gt; was the trigger for me. I wasn’t convinced by the iLife sync stuff nor the HDMI output, but the enormous list of hacks during the first week, while I was in San Diego, clicked on me. It was just too hackable not to have it, or, in the words of the &lt;a href=&#34;http://www.makezine.com/blog/archive/2006/11/owners_manifest.html&#34;&gt;Maker’s owner manifesto&lt;/a&gt;: “If you can’t open it, you don’t own it”.&lt;/p&gt;</description>

      <description>&lt;p&gt;10 reasons to meltdown your Harddisk:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;You realize you’re an idiot for not having a recent backup.&lt;/li&gt;&#xA;&lt;li&gt;You realize you’re a complete idiot for not having a backup at all (you had to delete the other one because you needed the space for MAME roms).&lt;/li&gt;&#xA;&lt;li&gt;You find the real value of storing &lt;em&gt;all&lt;/em&gt; your E-Mail on an IMAP server.&lt;/li&gt;&#xA;&lt;li&gt;You realize you should have the Sent folder on IMAP too.&lt;/li&gt;&#xA;&lt;li&gt;You find that your old Powerbook G4, now restored from scratch, is still a great machine to work with for next year, and therefore you save a bunch of money.&lt;/li&gt;&#xA;&lt;li&gt;You take the chance to renew and clean your RSS subscriptions, which you never had time to.&lt;/li&gt;&#xA;&lt;li&gt;During your quest to recover documents from your “IMAP disk-drive” you’ll find the most stupid things you believed in a couple of years ago. Makes you laugh, for a change.&lt;/li&gt;&#xA;&lt;li&gt;Keychain is great, but the low risk of fire or earthquakes still makes the good old paper an excellent alternative for storing passwords or secure notes (crying now).&lt;/li&gt;&#xA;&lt;li&gt;You’ll find the coolest Mac software you never bothered to check out before.&lt;/li&gt;&#xA;&lt;li&gt;You buy and actually use a backup utility until the drama is fresh.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;Yes, it all happened to me. The freaking drive is as dead as it gets. I’ve tried everything, Disk Warrior, Data Rescue II, dd_rescude and dd_rhelp on Linux (which are great by the way, don’t spend money on cute UIs, get a 2.5″ to 3.5″ HD cable and connect your drive to a Linux, dd_rhelp rocks. USB/IDE adaptors won’t work well because most times the driver will disconnect the faulty device) but no help. Managed to recover 240 Megs out of 80 Gigs and suddenly the HD collapsed from block 0 to the last.&lt;/p&gt;</description>

      <description>&lt;p&gt;Ainda dentro da mesma linha. As reuniões, essa infindável fonte de matéria prima para tiras do Dilbert, são a prova provada de que as organizações empresariais modernas não funcionam e que estão erradas. E não, não preciso de ter um MBA em gestão empresarial para ter legitimidade para dizer isto, a minha experiência profissional basta-me. As pessoas “reúnem-se” em exagero porque naturalmente, deixando a cultura corporativa fazer o seu trabalho, as soluções não aparecem. Se as soluções aparecessem de livre e espontânea vontade as pessoas só se precisavam de reunir para abrir a garrafa de champanhe.&lt;/p&gt;</description>

Fazem coisas fantásticas e surpreendentes sem precisarem de saber uma linha de &lt;a href=&#34;http://www.perl.com/&#34;&gt;Perl&lt;/a&gt; ou &lt;a href=&#34;http://www.php.net&#34;&gt;PHP&lt;/a&gt;, não podiam ser mais apáticas em relação às guerras dos Windows vs Linux, mal saberão o que é o “&lt;a href=&#34;http://www.gnu.org/software/bash/&#34;&gt;bash&lt;/a&gt;” ou o “&lt;a href=&#34;http://wwww.vim.org&#34;&gt;vi&lt;/a&gt;“, na sua maioria subcontratam a infra-estrutura aos amigos que percebem da coisa, os amigos mais velhos, os que sabem o que é o “vi”. Eles andem aí em Portugal e é de louvar, admirar e aprender com eles.&lt;/p&gt;</description>

      <description>&lt;p&gt;A melhor forma de aprender a viver e de dar valor ao que temos é a viajar, viajar muito. Este será um dos ensinamentos que incutirei aos meus filhos. Não há nada nesta vida que nos exponha a tanta diversidade, que coloque tantas verdades em perspectiva, e no fim que nos surpreenda e nos ensine tanto como estar em contacto com culturas e países diferentes daquele em que vivemos. Não há livro que nos consiga transmitir esta experiência nem a sabedoria que daí advém.&lt;/p&gt;</description>

      <description>&lt;p&gt;“Martelada” is the Portuguese word for what browser engines have to do to deal with the Web. The Web is broken in ways no one can imagine. I recently got involved in writing a small program to clone web pages and had to deal with rudimentary manual html parsing. Did you knew that:&lt;/p&gt;&#xA;&lt;ol&gt;&#xA;&lt;li&gt;&#xA;&lt;p&gt;&lt;a href=&#34;http://www.yahoo.com/&#34;&gt;Yahoo!’s Homepage&lt;/a&gt; refers to URLs in anchors without parenthesis or apostrophes just to spare a few bytes (and then they have a huge 30k banner at the same time) in the form &lt;a href=&#34;https://celso.io/images/ihavestandards.gif&#34;&gt; ?&lt;/a&gt;&lt;/p&gt;</description>

Being a satisfied .Mac subscriber since I have my Powerbook to sync my personal data between my work and my house in a efficiently and no-fuss way, I can’t help to feel that lately Apple is pushing it too much, and I don’t like it. .Mac is no more no less than a huge &lt;a href=&#34;http://www.faqs.org/rfcs/rfc2518.html&#34;&gt;Webdav&lt;/a&gt; server and remote storage, everything else is rendered and published by your local computer.&lt;/p&gt;</description>

      <description>&lt;p&gt;Do not trust anyone. Everyone&amp;rsquo;s fighting for their big chunk of an easy audience and quick fame, at any cost. Don&amp;rsquo;t bet your bucks on that good old trusty brand; you&amp;rsquo;ll get burned or fooled or both. The Internet is going through the same process public TVs had when competition arrived (think TVI if you live in Portugal).&lt;/p&gt;&#xA;&lt;p&gt;I see the most absurd news and theories every day. Being a relatively well informed IT guy, I read all my RSS feeds at the end of the day, and I find myself laughing most of the time. This whole &amp;ldquo;Ajaxified Web 2 bubble, Google is god don&amp;rsquo;t argue, let&amp;rsquo;s criticize the present and predict the future because we have a vision and have read the Web 2 meme map from Tim&amp;rdquo; thing has just gone too ridiculous. The extreme example of this madness is perhaps this Googleness about everything. OK, the company is a huge success, that&amp;rsquo;s a fact. They have a very well oiled and productive service factory, that&amp;rsquo;s a fact. They&amp;rsquo;re user-centric and scratched all their strategy (and mission) on top of that. They&amp;rsquo;re smart, IQ smart, I mean.&lt;/p&gt;</description>

This was my first mobile phone. The stunning &lt;a href=&#34;http://www.gsmarena.com/ericsson_ga_628-105.php&#34;&gt;GA628&lt;/a&gt; with 125 hours talk time, SMS and just 160g weight.

      <description>&lt;p&gt;I just tried to compile &lt;a href=&#34;http://www.livejournal.com/users/fraserspeirs/894516.html&#34;&gt;speirs’s Fotobilder iPhoto Plugin&lt;/a&gt; to use a modified version of our internal (SAPO’s) API, and translate it to Portuguese. So I downloaded the beta from &lt;a href=&#34;http://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wa/getSoftware?fileID=19767&amp;amp;source=x&amp;amp;code=y&#34;&gt;XCode2.2&lt;/a&gt; and gave it try.&lt;/p&gt;&#xA;&lt;p&gt;The last time I used a graphical IDE was on the glorious &lt;a href=&#34;http://www.amiga.com/&#34;&gt;Amiga&lt;/a&gt; days, with the famous &lt;a href=&#34;http://www.sas.com/products/sasc/&#34;&gt;SAS/C&lt;/a&gt; compiler. I long adopted the trusty portable gnu utils/bash/gnumake/vi IDE. So I was relutant.&lt;/p&gt;&#xA;&lt;p&gt;But &lt;a href=&#34;http://www.apple.com/macosx/features/xcode/&#34;&gt;XCode&lt;/a&gt; is beautiful. Apart for not being able to use “vi” decently, it just rocks. Without reading a single document or book, just out of common sense and knowledge I was able to install it XCode, the needed extra packages and frameworks, get the source code from &lt;a href=&#34;http://speirs.org/svn/Fotobilder/&#34;&gt;speir’s SVN&lt;/a&gt;, change the target for 10.4, edit the widgets to Portuguese, compile everything and run the program.&lt;/p&gt;</description>

      <description>&lt;p&gt;That’s right. Like cellphones, the iPod has long entered the accessories scam market. In fact, the iPod it self is not even Apple’s big profit but instead the economy that lives around it. Proof of it is that the accessory count&lt;a href=&#34;http://www.macmegasite.com/node/2445&#34;&gt; as reach 1000&lt;/a&gt;! Don’t you just hate when all your investment goes down the toilet when that new cool cellphone or iPod just suddenly changes the PC connector or battery charger adapter for no other reason than to revitalize a whole new series of gadgets and make money out of our vulnerable pockets ?&lt;/p&gt;</description>

      <title>GIM aka Google Talk is Out and working</title>

      <description>&lt;p&gt;It’s old news for Internet standards but Google Talk has opened their server (not the service yet).&lt;/p&gt;&#xA;&lt;p&gt;Enough to confirm it’s XMPP/Jabber. I was able to use my Gmail account both with Psi, iChat and AdiumX (libgaim based so all clients based on GAIM should work).&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Works with plain 5222 connections but you need TLS (Gaim clients and iChat support that)&lt;/li&gt;&#xA;&lt;li&gt;Works with SSL 5223 with any client, including Psi.&lt;/li&gt;&#xA;&lt;li&gt;You need to set “allow plain passwords” if your client has that option.&lt;/li&gt;&#xA;&lt;li&gt;S2S seems closed for the moment and no DNS SRV records are available for google.com, gmail,com or talk.gmail.com yet.&lt;/li&gt;&#xA;&lt;li&gt;No agents or components can be found while browsing (disco, agents or browse) for any of those domains.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;There’s some integration with the GMail webmail already, namely:&lt;/p&gt;</description>

      <guid>https://celso.io/posts/2005/08/24/update-on-google-talk/</guid>
      <description>&lt;p&gt;Well it’s out and lots of question have been answered both with the &lt;a href=&#34;http://www.google.com/talk/&#34;&gt;availability&lt;/a&gt; of the service and with a minimalist &lt;a href=&#34;http://www.google.com/talk/developer.html&#34;&gt;Developers FAQ&lt;/a&gt; on the site.&lt;/p&gt;&#xA;&lt;p&gt;In a nutshell:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;S2S and DNS SRV records are turned off. They don’t clarify if they’re going to open them, many speculate they will. For now they ask us to send them an E-Mail asking for federation. I did and received an Automatic reply with a ticket ID.&lt;/li&gt;&#xA;&lt;li&gt;When we invite a friend to GMail from our account, regardless of it’s E-Mail domain (initially I thought It would happen to .com contacts), it’s added to the XMPP roster. This is weird because they don’t have XMPP S2S open yet so I can’t IM them. But it’s the proof Gmail has a strong unified contact list engine behind the scenes.&lt;/li&gt;&#xA;&lt;li&gt;There’s a &lt;a href=&#34;http://groups.google.com/group/google-talk-open&#34;&gt;group&lt;/a&gt; for Google Talk discussions available.&lt;/li&gt;&#xA;&lt;li&gt;There’s some people asking for &lt;a href=&#34;http://www.asterisk.org/&#34;&gt;Asterisk’s&lt;/a&gt; native protocol &lt;a href=&#34;http://www.cornfed.com/iax.pdf&#34;&gt;IAX&lt;/a&gt; too.&lt;/li&gt;&#xA;&lt;li&gt;The VoIP/SIP people is wondering if they’re going to use &lt;a href=&#34;http://www.ietf.org/rfc/rfc2916.txt&#34;&gt;ENUM&lt;/a&gt; which would open the service further and contribute for interoperability.&lt;/li&gt;&#xA;&lt;li&gt;There are rumours that iChat could do voice call to Google Talk. Not true. Hoax.&lt;/li&gt;&#xA;&lt;li&gt;There’s no offline messages support. Rather than that, Google’s client uses GMail’s Webmail to send an E-Mail to your offline buddies.&lt;/li&gt;&#xA;&lt;li&gt;VoIP implementation and relationship with XMPP as not &lt;em&gt;yet&lt;/em&gt; been reverse engineered but it’s on many people’s TODO.list, including mine.&lt;/li&gt;&#xA;&lt;li&gt;Just crossed my mind that if you want, you now have a very easy and well &lt;a href=&#34;http://www.ietf.org/rfc/rfc3920.txt&#34;&gt;documented&lt;/a&gt; API to authenticate Gmail E-mail’s credentials.&lt;/li&gt;&#xA;&lt;li&gt;As you would expect from using XMPP you can logon with as many clients as you want (tried two) with the same account at the same time.&lt;/li&gt;&#xA;&lt;li&gt;People talked to me about Google Desktop integration but I haven’t checked.&lt;/li&gt;&#xA;&lt;li&gt;File transfers and avatars are not supported by Google’s client yet, so no JEP adoption advocacy for now &lt;img src=&#34;https://celso.io/assets/update-on-google-talk-1.jpg&#34; alt=&#34;:)&#34; title=&#34;:)&#34;&gt;&lt;/li&gt;&#xA;&lt;li&gt;Google’s client uses &lt;a href=&#34;http://www.jabber.org/jeps/jep-0115.html&#34;&gt;JEP-0115&lt;/a&gt; to query/inform the other peer’s client capabilities and reports the “voice-v1″ capability.&lt;/li&gt;&#xA;&lt;li&gt;Google’s client doesn’t respond to disco queries.&lt;/li&gt;&#xA;&lt;li&gt;Google’s client doesn’t send or react to jabber:x:event messages.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;&lt;strong&gt;UPDATE&lt;/strong&gt;: There’s an interesting &lt;a href=&#34;http://mail.jabber.org/pipermail/members/2005-August/003336.html&#34;&gt;thread&lt;/a&gt; going on the JSF members list. And a &lt;a href=&#34;http://mail.jabber.org/pipermail/members/2005-August/003347.html&#34;&gt;reply from stpeter&lt;/a&gt; which I fully subscribe.&lt;/p&gt;</description>

      <description>&lt;p&gt;Segundo o semanário “&lt;a href=&#34;http://semanal.expresso.clix.pt/&#34;&gt;Expresso&lt;/a&gt;” deste fim de semana o actual governo prepara-se para fazer uma &lt;a href=&#34;http://semanal.expresso.clix.pt/2caderno/default.asp?edition=1711&#34;&gt;parceria&lt;/a&gt; com os &lt;a href=&#34;http://www.ctt.pt/&#34;&gt;CTT&lt;/a&gt; e no âmbito do “&lt;a href=&#34;http://www.portugal.gov.pt/Portal/PT/Governos/Governos_Constitucionais/GC17/Programa/programa_p003.htm&#34;&gt;Choque/Plano tecnológico&lt;/a&gt;” dar um E-Mail a todos os cidadãos portugueses. O racional começa por ser o uso da Internet como meio privilegiado de contacto com os contribuintes como um instrumento de combate à fraude e à evasão fiscal (já se viu que a entrega electrónica do IRS é um &lt;a href=&#34;http://www.internet.gov.pt/media/noticia_ficha.asp?noticiaid=52&#34;&gt;sucesso&lt;/a&gt;) mas admite-se um uso mais abrangente, afinal de contas é um simples E-Mail na rede pública Internet. Fala-se também em certificação/garantia de recepção e entrega e mais, caso a mensagem não seja lida electronicamente é entregue fisicamente pelos CTT.&lt;/p&gt;</description>

      <description>&lt;p&gt;Alguém me consegue explicar porque é que este povo lusitano, quando viaja de avião (normalmente quando o faz em bloco), bate palmas quando o aparelho aterra ? Decerto que o tema já foi amplamente debatido mas eu não estou esclarecido e isto faz-me espécie…&#xA;Ora vejamos:&lt;/p&gt;&#xA;&lt;ul&gt;&#xA;&lt;li&gt;Não deve ser pela competência técnica do piloto nem pela perfeição ou elegância da aterragem. Não me parece que hajam grandes conhecedores da matéria a bordo. E para além disso já ouvi palmas nas aterragens suaves e nas mais turbulentas, com bom ou mau clima, em pistas difíceis ou fáceis.&lt;/li&gt;&#xA;&lt;li&gt;Há um certo efeito viral nesta coisa. O problema por vezes reside no elo mais fraco que desata a bater palmas. Dá-me a sensação de que se ninguém tomar a iniciativa, não acontece nada. Posso estar enganado. Esse elo mais fraco é muitas vezes também o engraçadinho que sabe que a parvoíce vai pegar se ele der o mote. Há também uma dose de palhaçada na coisa.&lt;/li&gt;&#xA;&lt;li&gt;É um fenómeno claramente associado à classe turística. Em executiva não há lá disto… com tanta frequência.&lt;/li&gt;&#xA;&lt;/ul&gt;&#xA;&lt;p&gt;Agora pergunto:&lt;/p&gt;</description>

      <description>&lt;p&gt;Impressões gerais sobre a Madeira: Desenvolvida, Excelentes acessos e infra-estruturas em qualquer canto da ilha, túneis em barda. Qualquer monte por mais pequeno que seja, justifica um. Há quem diga que até são demais, que a ilha já parece um queijo suíço. Vias rápidas e estradas secundárias em número mais do que suficiente. Gente afável e aparentemente trabalhadora, moldados pelas suas origens e percursos na vida, muitos são retornados. Mistela de línguas e raças nas ruas, em certos sítios é difícil ouvir falar-se Português ou até encontra-los. Nitidamente a Madeira é orientada para o turismo e na minha ignorância arrisco conjecturar que é dependente dele. Boa gastronomia. Linda. Grande. Diversificada desde o mar verde e quente do lado sul, às cascatas, montanhas, picos, escarpas com teleféricos assustadores, cabos, campos, vales, florestas e jardins, piscinas naturais, vilas históricas, levadas…&lt;/p&gt;</description>

      <description>&lt;p&gt;A few days ago, I &lt;a href=&#34;http://celso.arrifana.org/?p=13&#34;&gt;blogged about FOAF&lt;/a&gt;. Since then I’ve been more aware to simple solutions/approaches to the social face of the technical web. A few days after I stumbled across &lt;a href=&#34;http://gmpg.org/xfn/&#34;&gt;XFN&lt;/a&gt; /XHTML Friends Network), another very simple way to represent social relationships through annotations on the most used presentation language on the Internet: HTML. What else is out there ?&#xA;In the lack of a widespread adopted mechanism to represent user data and human relationships, there are many proposals laying around waiting for fame and fortune:&lt;/p&gt;</description>

      <description>&lt;p&gt;Neste fim de semana prolongado risquei mais um item da minha TODO-LIST pessoal, fui passá-lo aos Açores à Ilha de São Miguel. A expectativa era alta mas a experiência não desiludiu, este pedaço de terra plantado no meio do oceano é um exemplo vivo das maravilhas que a natureza tem e do que este País tão frequentemente se esquece. Deixo-vos algumas fotos para se deliciarem. A voltar, numa onda menos familiar e com mais tempo para ver as restantes pérolas deste arquipélago.&lt;/p&gt;</description>

      <description>&lt;p&gt;Por circunstâncias essencialmente casuais hoje estive presente na &lt;a href=&#34;http://www.diarioeconomico.com/edicion_impresa/imagenes/2005/PDF/plano.pdf&#34;&gt;conferência intitulada “Plano Tecnológico”&lt;/a&gt; promovida pelo &lt;a href=&#34;http://www.de.iol.pt/&#34;&gt;Diário Económico&lt;/a&gt; no &lt;a href=&#34;http://www.pestana.com/PT/Hoteis/LisboaPortoCascais/Palace/&#34;&gt;Pestana Palace Hotel em Lisboa&lt;/a&gt;. Tão casuais que não imaginei quando saí de casa que viesse a destacar-me (orgulhosamente, note-se) como o único desengravatado da audiência. Mas confesso que fui também com alguma dose de curiosidade ao encontro. Quando a bandeira de campanha do partido agora no governo é um “&lt;a href=&#34;http://www.ps.pt/bases/bp.htm&#34;&gt;Choque Tecnológico&lt;/a&gt;” para salvar a economia do País,  sendo a minha actividade profissional e os meus interesses pessoais fortemente ligados à tecnologia e à inovação e tendo eu acompanhado muito de perto estas guerras nos últimos dez anos de actividade sempre queria ver se hoje entendia como é que nos vão chocar. Mas não…&#xA;A conferência foi do meu ponto de vista, e como já devem ter percebido pelo meu tom de discurso, uma feira de vaidade cheia de altas individualidades ligadas a instituições governamentais, empresariais e de ensino, num habitat mediático, formal,  congestionado com fotógrafos, conselheiros, câmaras de televisão e equipas de reportagem. The works!&lt;/p&gt;</description>

      <description>&lt;p&gt;My Mac Mini just arrived at work. I asked for a 512 Meg RAM model and the “limited” local dealer sent me the Mini box, an Apple keyboard and a generic compatible 512 Meg RAM module for me to fit in. At first I thought they were just too lazy or costumer careless to plug the RAM for me but after my first attempt to open the beautiful silver cube I quickly realized that there was a very good reason for it.&#xA;The darned cube is as &lt;a href=&#34;http://nanocrew.net/blog/&#34;&gt;hard to open as the AAC DRM format&lt;/a&gt;, maybe harder (couldn’t resist sorry). After digging the net for some hacker’s experiences I also realized that either I needed:&lt;/p&gt;</description>

      <description>&lt;p&gt;Brutal. Peguem na experiência mais aventurosa que tiveram (para um indivíduo que se situe dentro dos padrões &lt;em&gt;standard&lt;/em&gt; da normalidade, claro seja), multipliquem por dez e não vão chegar nem perto à sensação que eu tive ao saltar de paraquedas de um Cessna com a cabine aberta a 4000 pés de altitude pela primeira vez…&lt;/p&gt;&#xA;&lt;p&gt;&amp;hellip; e pela segunda, terceira e quarta. O curso de abertura automática da &lt;a href=&#34;http://www.blue-emotions.pt/&#34;&gt;Blue Emotions&lt;/a&gt; já tinha começado há umas semanas atrás num dia nublado e ventoso e só ontem é que as condições meteorológicas proporcionaram a realização da parte prática. Depois de vários de fins de semana em que por via do mau tempo ou da (des)organização do evento não foi possível saltar, ontem lá foi mesmo. E foi assim:&lt;/p&gt;</description>

      <description>&lt;p&gt;As a newcomer to the blogging world that I am, and after some basic lessons I had about the way this community works I must say I’m very impressed with both the technical and social movement around this phenomena. Although I’m the Internet business, yes it never got me so obvious. It’s really the way information should be created and exist and there’s no stopping now, you big media corporations and so called opinion benders – be afraid!&lt;/p&gt;</description>

      <description>&lt;p&gt;&lt;strong&gt;iChat and XMPP/Jabber&lt;/strong&gt;&lt;/p&gt;&#xA;&lt;p&gt;Well it’s weekend and I decided to waste some time on something cool (“waste” is not exactly the term as working with Jabber is part of my professional activity, but I sure could find something more useful on my top_pri_todo_lst.txt, but not as fun).&lt;/p&gt;&#xA;&lt;p&gt;Ok 29 of April has finally arrived, Tiger was unleashed and I just love it. One of the most exciting new features is iChat support for the Jabber protocol (aka XMPP). Since XMPP support was announced on Tiger a few months ago, I’ve been most curious on how would they implement it and which JEPs would they support, if any.&lt;/p&gt;</description>
