<content:encoded><![CDATA[<div class='snap_preview'><p><img class="alignright size-medium wp-image-51320" title="Dell Chrome" src="http://jkontherun.wordpress.com/files/2009/11/dell-chrome.jpg?w=300" alt="" width="300" height="252" />You Dell (s dell) Mini 10v netbook owners who can&#8217;t wait to try the early builds of Google (s goog) Chrome OS on your system don&#8217;t have to wait any longer. You don&#8217;t even have to <a href="http://jkontherun.com/2009/11/20/first-look-at-google-chrome-os-extensions-options-and-more/">run it in a virtual machine like Kevin</a> did, because Dell has you covered. Some folks at Dell spent some time with Chrome and got it running on a Mini 10v. They got the drivers working properly, although Wi-Fi is a bit flaky, and put it all together in a <a href="http://linux.dell.com/files/cto/ChromiumOS_Mini10v_Nov25.img">neat package for owners to download</a>. Note that the download is a whopping 8 GB, and you should <a href="http://www.liliputing.com/2009/11/dell-provides-custom-google-chrome-os-image-for-mini-10v-users.html">follow the instructions</a> to get it working properly.</p>
<p>It&#8217;s nice to see Dell jump on Chrome OS so quickly. It bodes well that Dell might be officially supporting Chrome in the future.</p>

<description><![CDATA[Netbooks, low-cost portable computers optimized for web usage, are continuing to sell at a torrid pa]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p><img class="alignleft size-full wp-image-83046" title="3326126941_c1a7050cfd_o" src="http://gigaom.wordpress.com/files/2009/11/3326126941_c1a7050cfd_o.jpg" alt="" width="163" height="146" />Netbooks, low-cost portable computers optimized for web usage, are continuing to sell at a torrid pace, with <a href="http://www.pcmag.com/article2/0,2817,2356376,00.asp">Acer expecting 50 percent growth in the global netbook market in 2010, to 42 million units</a>. In the meantime, standard technologies, operating systems and other options in these diminutive systems are undergoing rapid shifts. Here are eight up-to-date tips to keep in mind if you&#8217;re in the market for a new netbook.</p>
<p><strong>Don&#8217;t Settle for a Tiny Display.</strong> <a href="http://gigaom.com/2009/10/12/notebooks-vs-netbooks-can-you-tell-the-difference/">As Om has pointed out</a>, netbook specifications continue to encroach on standard laptop specs, to the point that the real differences between them are blurring. And as The Register and market researchers at Canalys <a href="http://www.reghardware.co.uk/2009/11/27/vendor_netbook_roadmap/">report</a>, in 2010, many netbook manufacturers will be emphasizing systems with 12-inch displays, to possibly broadly replace those with screens of just 10 inches. You can already find systems with larger displays, and indeed, you&#8217;ll likely have a better experience with them.</p>
<p><strong>Don&#8217;t Go for a Tiny Keyboard. </strong>Many netbooks come with chiclet-style keyboards that can make typing difficult, but this is rapidly changing. <a href="http://www.pcmag.com/article2/0,2817,2356235,00.asp">As PCMag.com notes</a>, many new netbooks, such as the <a href="http://www.pcmag.com/article2/0,2817,2349045,00.asp">Toshiba mini NB205</a>, come with full-size keyboards. I&#8217;m also a fan of the keyboards on the Acer Aspire One and Dell Mini 10v systems. Get a keyboard that won&#8217;t cramp your style &#8212; that&#8217;s where the market is headed.</p>
<p><strong>Consider the OS Up Front.</strong> Linux-based netbooks continue to offer low price points and often come with good open source applications. Next year, Google (s goog) <a href="http://gigaom.com/2009/11/19/chrome-os-unveiled-focused-on-netbooks-the-cloud/"> will attempt to redefine the netbook</a> with its Linux-based Chrome OS, focused on cloud applications. In the meantime, Microsoft&#8217;s (s MSFT) new Windows 7 operating system is squarely aimed at the netbook market, and netbook manufacturers <a href="http://www.pcmag.com/article2/0,2817,2356376,00.asp">are reporting</a> that it&#8217;s ushering in strong sales.  As always, consider what types of applications you&#8217;ll use as you weigh various operating systems.</p>
<p><strong>Free Apps Can Improve Your Experience. </strong>When evaluating a netbook&#8217;s platform and what you&#8217;ll do with it, don&#8217;t forget that there are many free and open source utilities and applications that make navigating, handling hardware resources and other tasks easier. You can <a href="http://gigaom.com/2008/12/02/10-ways-to-trick-out-your-netbook/">find 10 good ideas here</a>.</p>
<p><strong>Complement Low Local Storage With a USB Drive.</strong> Netbooks typically make many compromises in terms of local resources when compared to larger laptops, with storage among the most common. You can complement low local storage <a href="http://gigaom.com/2009/10/26/using-a-netbook-add-a-muscular-usb-flash-drive-to-the-mix/">with an inexpensive, external USB Flash drive</a>, however. There are also useful web sites, especially <a href="http://portableapps.com/">PortableApps</a>, that you can use to stock up your Flash drive with useful, free applications.</p>
<p><strong>Check the Battery Life.</strong> Many netbooks offer outstanding battery life &#8212; in some cases, all-day power &#8212; but not all of them. Make sure to check reviews of the netbook you&#8217;re considering for battery life tests. And once you&#8217;ve become a netbook owner, remember to <a href="http://webworkerdaily.com/2009/01/05/8-ways-to-get-better-battery-life/">follow best practices</a> &#8212; especially turning the brightness down &#8212; in order to maximize its battery life.</p>
<p><strong>Take a Hands-On Test Drive.</strong> While there are many good deals online for netbooks, if possible, I recommend going to a retail outlet to do a hands-on test drive. Because netbooks are practically defined by the compromises they make, this can help you identify any problems that you might find intolerable over time.</p>
<p><strong>Pointing Devices Matter.</strong> Speaking of personal preferences, people always vary widely in terms of the pointing devices they favor. For example, I&#8217;ve tried many netbooks that I would never buy simply because the highly sensitive trackpads on them bother me. This is another reason why a hands-on test drive makes a lot of sense.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p><a href="http://www.nokia.de/" target="_blank">Nokia</a> hat sein erstes Netbook auf den Markt gebracht und setzt dabei auf Design. Das Netbook kommt mit einem schicken Alu-Gehäuse daher, das allerdings mit einem Kunststoffdeckel versehen ist. Der 10,1“-Bildschirm (verspiegelt) hat eine Auflösung von 1280&#215;720 Pixel, die CPU ist ein Intel Atom Z530 mit 1,6GHz. Als Betriebssystem wurde Windows 7 Starter Edition gewählt, das auf einer 120 GB-Festplatte (1,8“) vorinstalliert ist. Leider wurde nur 1GB Ram verbaut.</p>
<p>Das 1,2 Kilogramm leichte Netbook wurde mit einem 16 Zellen Akku ausgestattet, das laut Nokia bis zu 12 Stunden Energie liefern soll. Das ist wohl etwas übertrieben, aber bis zu acht Stunden soll der Akku schon reichen, was ebenfalls ein exzellenter Wert ist. Als Besonderheiten wurden ein UMTS-Modem und ein GPS-Empfänger im Netbook integriert.</p>
<p>Das Nokia Booklet 3G kostet im Netz rund 730 Euro. Bei Youtube gibt es schon ein paar schöne Unboxing-Videos. Z.B. das hier:</p>
<p><span style='text-align:center; display: block;'><object width='425' height='350'><param name='movie' value='http://www.youtube.com/v/YjCs-nHqES0&#038;rel=1&#038;fs=1&#038;showsearch=0&#038;hd=0' /><param name='allowfullscreen' value='true' /><param name='wmode' value='transparent' /><embed src='http://www.youtube.com/v/YjCs-nHqES0&#038;rel=1&#038;fs=1&#038;showsearch=0&#038;hd=0' type='application/x-shockwave-flash' allowfullscreen='true' width='425' height='350' wmode='transparent'></embed></object></span></p>
<p><strong>Mein Kommentar dazu</strong><br />
Ein wirklich schönes Designteil mit dem man auch schon mal im Szenecafé gegen die Mac-Books „anstinken“ kann. Allerdings sollte man vorher den sehr auffällig platzierten Windows 7-Aufkleber abkratzen. Mich persönlich würde der wirklich hohe Preis abschrecken. Sicher, die Verarbeitungsqualität ist hoch, aber trotzdem erhalte ich ein relativ normales Netbook. Wie wäre es denn mal mit einem schönen Flash-Speicher anstatt einer schnöden Festplatte, 2GB Ram und einem matten Display? Aber vielleicht passiert da ja noch was.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p><img class="alignleft size-full wp-image-484" title="3g" src="http://almalivre.wordpress.com/files/2009/08/3g.jpg" alt="" width="273" height="178" />Já há algum tempo não posto nada sobre o assunto da conexão 3G, e ainda estava devendo um artigo sobre os repetidores de sinal. Então estou pagando minha dívida hoje.</p>
<h3>O que são repetidores de sinal?</h3>
<p>Imagine que você está numa fazenda a 50 km da antena de celular mais próxima. Seu celular (ou seu modem) não conseguiria conectar nessas condições, nem se você subisse no telhado. Por esse motivo, fazendas no interior desse Brasilzão utilizam antenas direcionais de alto ganho para captar o sinal da ERB mais próxima e fornece-lo a um aparelho, através de um cabo. Isso tira completamente a mobilidade do aparelho.</p>
<p><!--more-->Imagine, então, que fosse possível pegar esse sinal da antena e transferi-lo para outra antena, dentro de casa. Do lade de fora da casa você tem uma torre, ou um cano (como nas antenas de TV) com uma antena direcional (que só pega sinal de um lado), apontada para a ERB. Um cabo conectado a essa antena desce pelo cano (ou torre), entra para dentro da casa e, ao invés de ser c onectado ao seu celular (ou modem), seria conectado a uma outra antena (omnidirecional, ou seja, que transmite para todos os lados), que retransmitiria o sinal captado pela antena externa no ambiente interno.</p>
<h3>Isso é possível?</h3>
<p>Sim, é possível. Tem duas maneiras de se fazer:</p>
<p>1 &#8211; através de um repetidor passivo, ou seja, ele não atua ativamente no sinal para amplifica-lo. Ele apenas pega o sinal recebido e o entrega à antena interna para que distribua internamente.</p>
<p>2 &#8211; através de um repetidor ativo, que nada mais é do que um amplificador de sinal bidirecional, que pega o sinal da antena externa e o amplifica antes de entregá-lo à antena interna e vice versa.</p>
<p>Vejam bem, estamos falando aqui de um tráfego bidirecional, ou seja, não basta captar o sinal da ERB e entrega-lo no celular (ou modem). É necessário fazer o inverso também: pegar o sinal gerado pelo modem e entrega-lo à ERB. Então temos três situações:</p>
<p>1 &#8211; O sinal da ERB é bom, mas o sinal do modem é fraco. Isso acontece, por exemplo, quando recebemos o sinal da ERB reflatido em algum obstáculo, como prédios ou morros. Nesse caso, não há como resolver o problema com repetidores passivos. É preciso uma amplificação real do sinal do modem para que a ERB o &#8220;ouça&#8221;.</p>
<p>2 &#8211; O sinal da ERB é fraco porque está distante. Neste caso, é possível jutilizar um repetidor passivo, mas tudo vai depender da distância e do nível de sinal. Eu diria que para distâncias de uns 4 ou 5 km (talvez mais, dependendo da qualidade das antenas, cabos, conectores, soldas, etc.), poderia ser uma solução viável.</p>
<p>3 &#8211; O sinal da ERB é fraco porque há obstáculos. Neste caso, é muito possível a utilização de um repetidor passivo, porque podemos encontrar um local próximo onde o sinal seja bom, instalar a antena externa e levar o sinal através de um cabo até o local onde o sinal é fraco, sem necessidade de amplificação ativa.</p>
<h3>Soluções</h3>
<p>No primeiro caso, A solução necessariamente passa por um repetidor ativo, ou seja, um amplificador que aumentará o sinal em ambas as direções. Tais soluções são caras, mas muito eficientes. De qualquer forma, antes de fazer qualquer investimento numa solução dessas, é extremamente recomendável que você consulte um técnico experiente como eu (:D) para fazer uma avaliação do local e sugerir as possíveis soluções (ativo, passivo, tipo de antena, local de instalação, etc). Sugiro isso, não por purismo, mas por prudência (se você gosta do seu dinheiro) às vezes é melhor pagar um técnico para te dizer que não vai dar certo, do que comprar o equipamento e depois descobrir que ele não vai servir de nada.</p>
<p>No segundo caso, dependendo das condições, é possível utilizar um ou outro. No geral, quanto maior a distância, pior o sinal e maior a possibilidade de você precisar de um amplificador. Novamente, só um técnico vai poder dizer qual a melhor solução.</p>
<p>No terceiro caso, é possível apelar para gambiarras mais econômicas mas, se você não quer ter dores de cabeça, novamente, chame um técnico.</p>
<h3>Tipos de antenas</h3>
<p>As antenas direcionais podem ser de vários tipos. Os mais populares são as Yagi, as parabólicas e as setoriais (ou de painel). Não importa muito o tipo da antena, mas importam suas características elétricas. O que você tem de verificar antes de comprar são: ganho, impedância e faixa de frequências de utilização.</p>
<p>Ganho &#8211; Uma antena, a priori, não amplifica um sinal. Quando dizemos que uma antena tem um &#8220;ganho&#8221;, na verdade é uma comparação dela com um tipo de antena chamado &#8220;isotrópica&#8221;, ou seja, que recebe sinais de todas as direções e não amplifica nem atenua nada. Na prática esse tipo de antena não existe e o que mais chega perto disso são as antenas omnidirecionais de um quarto de onda de ganho único. Portanto, podemos a grosso modo (muito grosso mesmo), dizer que uma antena que tem um &#8220;ganho&#8221;, na verdade recebe melhor &#8220;tantas vezes&#8221; em relação a esse tipo de antena. Antenas direcionais sempre têm um &#8220;ganho&#8221; maior do que antenas omnidirecionais. Isso acontece porque o seu desenho &#8220;transfere&#8221; as características omnidirecionais de uma antena comum para um único lado. Ou seja, é uma antena omnidirecional que foi &#8220;trabalhada&#8221; para que concentrasse toda a sua &#8220;força&#8221; de um único lado, de forma que os ganhos unitários das outras direções se &#8220;somem&#8221; em uma única direção.</p>
<p>Impedância &#8211; Não vou explicar aqui o que significa o termo. Apenas vou dizer que as impedâncias da antena, do cabo utilizado e da outra antena (ou da entrada do amplificador) devem ser as mesmas. Caso contrário, todo o trabalho corre o risco de não dar o resultado esperado, pra não dizer que não vai funcionar de jeito nenhum. A impedância mais utilizada para antenas de celular é 50 ohms, portanto, nada de usar cabos de antena de TV (75 ohms) pra fazer as conexões.</p>
<p>Faixa de frequências &#8211; Toda antena é construída para funcionar numa determinada frequência, com uma variação pequena para cima ou para baixo. A mesma antena pode ser utilizada para frequências múltiplas da frequência original (uma antena para 2,4 GHz pode ser usada para 1,2GHz ou para 4,8 GHz), mas suas características eletromagnéticas mudam, o que altera o ganho e, consequentemente o funcionamento. Portanto, use a antena certa para a frequência correta. No caso do 3G no Brasil, a maior parte dos locais é servido pela frequência de 2,4 GHz.</p>
<h3>Vamos à prática!</h3>
<p>Procure adquirir antenas de boa qualidade ou, se desejar construí-las, seja bem criterioso.</p>
<p>Antenas: Abaixo você pode ver exemplos de antenas Yagi, parabólica, setorial e omnidirecional.</p>

<div id="attachment_1018" class="wp-caption aligncenter" style="width: 140px"><img class="size-full wp-image-1018" title="omnidirecional" src="http://almalivre.wordpress.com/files/2009/11/omnidirecional.jpg" alt="Omnidirecional" width="130" height="200" /><p class="wp-caption-text">Omnidirecional</p></div>
<h3>Macetes:</h3>
<p>1 &#8211; O comprimento do cabo entre a antena externa e a interna (ou amplificador), deve ser um múltiplo da metade do comprimento de onda da frequência utilizada. No caso dos 2,4 GHz, o comprimento do cabo deve ser múltiplo de 6,25 cm, ou o,o625 metros. Procure ser exato. Um tantinho a mais, ou a menos, pode ser a diferença entre dar certo ou não.</p>
<p>2 &#8211; Procure utilizar conectores soldados. Cada conexão gera uma perda de 1dB, aproximadamente. Se você não utilizar adaptadores, só nos conectores das antenas externa e interna serão 2dB de perda. Quanto maior o cabo, maior a perda. Se você não prestar atenção nesses detalhes, todo o ganho obtido pela antena pode ser perdido no cabo e nas conexões.Além disso, conexões mal feitas geram ruídos que interferem no sinal. Portanto, não bobeie.</p>
<p>3 &#8211; Se houver sobras no cabo, procure eliminá-las. Não enrole a sobra. Por dois motivos: o cabo excedente diminui o sinal nas pontas e a espiral pode agir como um indutor, alterando alguma característica do sistema.</p>
<p>4 &#8211; Se for necessário utilizar adaptadores, utilize o seguinte critério: o cabo mais fino é sempre o menor. E quanto menor, melhor.</p>
<p>5 &#8211; Na antena externa, procure isolar bem o conector com fita de autofusão e cola de silicone. Se chover e entrar água no conector, não tem santo que vai ajudar. Você terá de desmontá-lo, secá-lo e montá-lo novamente, dessa vez do jeito certo. Conectores externos têm uma facilidade enorme de oxidarem gerando mal contato. Por isso, seja muito cuidadoso nessa parte.</p>
<h3>Repetidores ativos (amplificadores).</h3>
<p>Quem mora em fazenda, com certeza já conhece esses aparelhos. São equipamentos que pegam um sinal vindo de uma antena externa e amplificam, disponibilizando-o em um ambiente interno (e vice-versa).</p>
<p>Um exemplo desse tipo de aparelho está na foto abaixo. Mas lembre-se: são equipamentos de um custo razoável, portanto, pode tornar alto o custo total (acesso, modem, antenas, torre ou mastro, cabos e conectores, amplificador, instalação e assistência técnica). Portanto, avalie bem se vale a pena o custo para o benefício que tudo isso pode trazer.</p>
<div id="attachment_1019" class="wp-caption aligncenter" style="width: 210px"><img class="size-full wp-image-1019" title="repetidor" src="http://almalivre.wordpress.com/files/2009/11/repetidor.jpg" alt="Repetidor amplificador de sinal celular" width="200" height="200" /><p class="wp-caption-text">Repetidor amplificador de sinal celular</p></div>
<div id="attachment_1020" class="wp-caption aligncenter" style="width: 660px"><img class="size-full wp-image-1020" title="esquema de ligação" src="http://almalivre.wordpress.com/files/2009/11/esquema-de-ligacao.png" alt="Esquema de ligação" width="650" height="357" /><p class="wp-caption-text">Esquema de ligação</p></div>
<p>A diferença entre o esquema amplificado acima para o repetidor passivo, é que neste último, o cabo de descida vai direto na antena interna. Com certeza alguém vai perguntar se dá pra usar antenas caseiras com esse esquema. A resposta é sim. No entanto, se você for utilizar um amplificador como na figura acima, isso pode ser entendido como violação da garantia do produto. Não há contra indicações no caso do repetidor passivo.</p>

<description><![CDATA[Smartbooks are an emerging class of computing devices that, basically, are to netbooks what netbooks]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p><a href="http://news.cnet.com/8301-13924_3-10400275-64.html">Smartbooks</a> are an emerging class of computing devices that, basically, are to netbooks what netbooks are to notebooks: smaller, cheaper, less powerful, and (possibly) handier. They&#8217;re an idea being promoted by chipmakers Qualcomm and Freescale, whose CPUs will be inside the machines (which won&#8217;t run Windows).</p>
<p><span style='text-align:center; display: block;'><object width='425' height='350'><param name='movie' value='http://www.youtube.com/v/3WznqM-TLv0&#038;rel=1&#038;fs=1&#038;showsearch=0&#038;hd=0' /><param name='allowfullscreen' value='true' /><param name='wmode' value='transparent' /><embed src='http://www.youtube.com/v/3WznqM-TLv0&#038;rel=1&#038;fs=1&#038;showsearch=0&#038;hd=0' type='application/x-shockwave-flash' allowfullscreen='true' width='425' height='350' wmode='transparent'></embed></object></span></p>
<p>Trouble is, there&#8217;s already a smartbook. It&#8217;s a German company, and as TechCrunch&#8217;s Robin Wauters is reporting, <a href="http://www.youtube.com/watch?v=3WznqM-TLv0&#38;feature=player_embedded">it&#8217;s decided to protect its trademark by going after use of the term to describe these mini-netbooks</a>.</p>
<p><!--more--></p>
<p>The whole situation is reminiscent of <a href="http://technologizer.com/2008/12/24/we-may-need-a-new-name-for-netbooks/">Psion&#8217;s period of trying to stomp out use of &#8220;netbook&#8221;</a> (which was <a href="http://news.cnet.com/8301-1001_3-10253210-92.html">soon resolved</a>). This time, though, I&#8217;d shed no tears if the chip companies and others behind the new gadgets were forced to to find a new name for their platform. Unless you want to argue that smartbooks are, indeed, the smartest computing device to date, the term isn&#8217;t descriptive. Unlike &#8220;desktop&#8221; or &#8220;notebook&#8221;  it&#8217;s just marketingspeak. Even &#8220;smartphone&#8221; is clearer, since smartphones are indeed smarter than mere phones.</p>
<p>The category is tough to describe in a clear way: Intel&#8217;s similar <a href="http://news.cnet.com/8301-1001_3-10253210-92.html">MID (Mobile Internet Device) concept</a> isn&#8217;t very helpful or alluring. But here are few stabs at new terminology, just in case we need it:</p>
<ul>
<li>Netnetbook</li>
<li>Netbookerino</li>
<li>Tinybook</li>
<li>Smallishbook</li>
<li>Leanbook</li>
<li>Kneetop</li>
<li>Netpaperback</li>
</ul>
<p>Any other candidates?</p>
<p>The real question about smartbooks, of course, is whether the world needs &#8216;em. I&#8217;m looking forward to seeing some examples in person in January at the Consumer Electronics Show. Historically, the track record of devices too big to fit in a pocket and too limited to serve as full-blown computers has been crummy. (Sorry, <a href="http://www.ultramobilelife.com/">UMPCs</a>.) But with the rise of smartphones and the decline of operating systems as the defining factor that determines what you can do with a computer, smartbooks aren&#8217;t an inherently nutty idea.</p>

<description><![CDATA[Para los que no entiendan inglés, Google Chrome OS será un sistema operativo que estará muy ligado a]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p>Para los que no entiendan inglés, <strong>Google Chrome OS</strong> será un <strong>sistema operativo</strong> que estará muy ligado al hardware (sólo netbooks) y no podrá ser instalado en cualquier máquina. La netbook se enciende y en pocos segundos se cargará <strong>Google Chrome</strong> (el <strong>navegador</strong> web) que nos dará acceso a todos <strong>nuestros datos guardados en la nube</strong>.</p>
<p>No será para todos los usuarios, porque algunos querrán tener sus datos en sus propios discos o usar su propio software y tener instalado su propio sistema operativo (GNU/Linux) como más le gusta, pero digamos&#8230; <strong>¿la mitad? (siendo conservador) de la gente</strong> sólo usa la computadora para navegar, consultar el correo, chat, mensajería instantánea, VoIP (voz), Calendario, Facebook, Twitter, YouTube, herramientas colaborativas como Google Wave, procesador de texto, presentaciones, planilla de cálculo&#8230; y no necesitan más nada.</p>
<p style="text-align:center;"><span style='text-align:center; display: block;'><object width='425' height='350'><param name='movie' value='http://www.youtube.com/v/VhcjvK4rjQY&#038;rel=1&#038;fs=1&#038;showsearch=0&#038;hd=0' /><param name='allowfullscreen' value='true' /><param name='wmode' value='transparent' /><embed src='http://www.youtube.com/v/VhcjvK4rjQY&#038;rel=1&#038;fs=1&#038;showsearch=0&#038;hd=0' type='application/x-shockwave-flash' allowfullscreen='true' width='425' height='350' wmode='transparent'></embed></object></span></p>
<p>Con un <strong>pequeño</strong> disco duro o de estado sólido, o con unos <strong>pendrives</strong> &#8220;de regalo&#8221; con la compra de la netbook para que cada miembro de la familia pueda tener su backup a la mano será suficiente. Tal vez un <strong>disco duro &#8220;familiar&#8221;</strong> que se conecte en forma inalámbrica a la netbook pueda realizar <strong>backups automáticos</strong> (o con una interfaz web gracias a una extensión o plugin de Chrome) y quizás almacenar algunas cosas que no querramos subir a la nube (privacidad, velocidad, etc.).</p>
<p>Con los <strong>procesadores</strong> actuales <strong>es más que suficiente</strong> para este tipo de aplicaciones basadas en la nube (Internet). Lo digo yo que uso mi notebook de 1,6 MHz y 1 GB de <strong>RAM</strong> de esa forma, el 70 % del tiempo. Con Ubuntu 9.10 &#8220;Karmic Koala&#8221; me sobra la mitad del poder de cálculo y casi la mitad de la memoria RAM. Y además, <strong>sin disco</strong>, las vida útil y duración de las <strong>baterías</strong> sería el triple. Incluso la netbook podría entrar en hibernación (salvar el estado de la memoria RAM en disco) si no la usamos, y estar de nuevo encendida y lista en un par de segundos.</p>
<p><strong>Con Google Chrome OS</strong> le hacemos <strong>chau</strong> a las demoras al encender (booteo), chau comprar (o piratear) el Windows (o instalar GNU/Linux), chau particionar, chau antivirus, chau problemas de controladores (drivers), chau problemas de codecs (decodificadores de audio y video), chau actualizaciones y parches: <strong>Bienvenidos al escritorio personal móvil</strong>. Donde quiera que vayamos, en cualquier computadora, tendremos nuestro escritorio de siempre, <strong>perfectamente sincronizado</strong>: papel tapiz, salva pantallas, extensiones, configuraciones, marcadores, etc.</p>
<p>Claro que para que esto sea viable en los países desarrollados hará falta más inversión en fibra óptica, WiMax y toda tecnología capaz de <strong>acelerar los flujos de datos y hacer la Red de redes omnipresente</strong> (conectividad en todas partes, no sólo en las grandes ciudades). ¿La conexión será al fin un derecho universal? ¿O tendremos que pagar a las Telefónicas para poder acceder a nuestros datos? ¿Ofrecerá Google una conexión gratuita a quienes compren &#8220;su&#8221; netbook?</p>
<p>La salida al mercado de este nuevo &#8220;sistema operativo&#8221; de Google para netbooks está prevista <strong>para fines de 2010</strong> y tal vez no sea el gigante de las búsquedas (y de todo lo demás) el único que adopte este nuevo paradigma, una nueva forma de usar las computadoras por parte de la mayoría de la gente. Seguirán habiendo poderosas PCs de escritorio para los jugadores o editores de audio y video, y se seguirán vendiendo notebooks con grandes pantallas para tareas de oficina o juegos con menores requerimientos de hardware, pero todo el mundo tendrá sus dispositivos móviles a la mano: smartphones (teléfonos inteligentes), lectores de libros digitales con conexión a Internet, Tablets y netbooks que nos permitirán hacer lo que hacemmos todos los días con estas computadoras más lentas, más caras y más difíciles de instalar, usar y mantener.</p>
<p>A lo anterior lo doy por seguro, pero me quedan algunas incógnitas:</p>
<ul>
<li> ¿Cuántos usuarios (y ventas) perderá Microsoft (Windows, Office, etc)?</li>
<li>¿Habrá una explosión de software libre?</li>
<li>¿Será el fin del malware basado en las fallas del sistema operativo?</li>
<li>¿Mudarán las empresas antivirus hacia software que minimice la amenaza de los ataques &#8220;sociales&#8221;?</li>
<li>A la plataforma Google Chrome OS ¿le seguirá otra de Canonical, con Ubuntu Netbook Edition + Ubuntu One?</li>
<li>¿Y las empresas de teléfonos celulares (smartphones)?</li>
<li>¿Y Apple?</li>
</ul>
<p>Falta un año. O menos. Y voy enlistando más avances de la tecnología en <a href="http://inquietamente.wordpress.com/tecno-tips/">Tecno-tips</a>.</p>

The X120 is your basic Intel Atom (s intc) powered netbook with a 160 GB hard drive, 1 GB of RAM and Microsoft Windows XP (s msft). LG expects the six-cell battery to last for seven hours. Along with Wi-Fi, the 2.8 pound X120 includes an HSPA radio tuned to AT&#38;T&#8217;s (s t) 3G frequencies, making it a perfect candidate for a data plan. That&#8217;s exactly what you&#8217;ll need, too &#8212; a $60 monthly data plan &#8212; to grab the X120 for $179.99 at your local Radio Shack.</p>
<p>LG also integrated <a href="http://www.splashtop.com/">Splashtop&#8217;s instant on solution</a> for quick access to key applications an a connected browser. A dedicated &#8220;SmartOn&#8221; button boots the netbook into a basic Linux partition, making you productive in five seconds. When I last chatted with the DeviceVM folks &#8212; creators of Splashtop &#8211; nearly a year ago, <a href="http://jkontherun.com/2009/01/08/3-huge-differences-between-phoenix-hyperspace-devicevm-splashtop/">they were still working on getting their product to work with 3G connections</a> like the one included with the X120. I expect they have that ironed out now, but I&#8217;ll ping them directly to verify. As nice as a five-second boot time is, I&#8217;d want to use the browser wherever I am.</p>

<description><![CDATA[In its heyday, DELL, as now, assembled and sold desktops and laptops, primarily to business and gove]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p>In its heyday, DELL, as now, assembled and sold desktops and laptops, primarily to business and government but also to consumers.  The desktops were utilitarian, the laptops not particularly stylish and a bit heavier than others.  But all DELL&#8217;s products were serviceable and they were cheap.</p>
<p><strong>DELL&#8217;s advantages&#8230;</strong></p>
<p><strong> </strong>DELL had several advantages over its competition:</p>
<p>1.  it dealt directly with the end consumer, assembling machines to order.  So it had virtually no finished goods inventory</p>
<p>2.  component manufacturers suffered from chronic overcapacity.  So their prices were generally falling.  DELL took delivery of parts on the day a machine was assembled and sold, rather than having a finished machine sitting on a shelf for three months before purchase.  This gave the company a several percentage point cost of goods advantage over rivals.</p>
<p>3.  competitors were weak.  IBM wasn&#8217;t sending its best and brightest to make PCs.   A Jobs-less AAPL was drifting.  Compaq was very inefficient, as was HP.  HP then compounded its problems by hiring Carly Fiorina&#8211;a marketer with little manufacturing experience&#8211;and acquiring Compaq.</p>
<p>4.  DELL uses a negative working capital business model.  That is, customers pay for their DELL computers at present on average 36 days earlier than DELL pays its suppliers and workers for making the machines.  Also, DELL receives payment for warranty or other service contracts in advance.  When short-term interest rates were higher than now, DELL could earn hundreds of millions of dollars in interest income on these &#8220;floating&#8221; balances.</p>
<p><strong>..where did they all go?</strong></p>
<p><strong> </strong>What happened is this:</p>
<p>1.  component making became more sophisticated and expensive.  Suppliers consolidated or dropped out of the business.  Chronic overcapacity abated.  We now appear to be entering, if anything, a period of component shortage.</p>
<p>2.  IBM sold its PC-making business to Lenovo.  Jobs returned to AAPL.  Fiorina was shown the door at HPQ, which promptly hired a veteran manufacturing manager, Mark Hurd, from NCR.  Acer and ASUS emerged as global players in the PC market with low-cost netbooks.</p>
<p>3.  Consumer tastes shifted from heavy and clunky to smartphones, netboooks and sleeker Macs.  DELL didn&#8217;t adjust, although it&#8217;s trying to do so now.</p>
<p>4.  Vista arrived, causing consumer disenchantment with MSFT-driven computers and encouraging businesses to stay with Windows XP.</p>
<p>5.  The Great Recession developed.  Not only did this reduce demand, but it lowered short-term interest rates to almost nothing, all but erasing DELL&#8217;s once significant interest income.</p>
<p><em>Not all the issues were external, </em>however<em>.</em></p>
<p>6.  DELL&#8217;s quality control and customer service, at least in its consumer business, slipped badly.</p>
<p><strong>Where to from here?</strong></p>
<p>Michael Dell, the company founder, returned to the helm to right a troubled ship in early 2007.</p>
<p>His initial goals were to reduce manufacturing costs and increase production efficiency, in order to raise margins and reverse a sharp slippage in the effectiveness of the company&#8217;s negative working capital model.</p>
<p>DELL has also been trying to rationalize product lines (fewer models) and simplify product design.  To this end, it is increasingly turning away from its own manufacturing plants and using contract manufacturers.</p>
<p>I&#8217;ve read that Mr. Dell also at least initially wanted to expand the company&#8217;s consumer device offerings.  But I can see no specific evidence of this desire in company documents on the website.  And in any event, it seems to me that this market&#8211;which is now iPhone, iTouch, Blackberry, Android, netbook&#8211;has pretty much run away from DELL.</p>
<p>(By the way, I&#8217;ve found the company website much more open and accessible than it was a few years ago, when it was impossible, even as a professional investor, to arrange to get on the company&#8217;s email alert list.  The new reporting format this year is also a big step up in delivering relevant investor data.)</p>
<p>International expansion is another theme.</p>
<p>So to is creation of a much larger service business, so that DELL can have more recurring revenue and be less dependent on the PC replacement cycle with large enterprises and government entities.  Hence, the $4 billion (cash) Perot Systems acquisition, which has just closed.</p>
<p><strong>A tough row to hoe</strong></p>
<p><strong></strong><em>T</em><em>o sum up</em>:   DELL appears to have decided to  start down the same path that IBM began to tread in the late Nineties and onto which HPQ turned two years or so ago.  This seems to be the natural evolution of the IT business&#8211;from hardware to software and services.  Two big issues for DELL:   it&#8217;s a little late to the game, and the competition is not only ahead of it in this move, but also much less concentrated than DELL is on enterprise and government PCs and servers (about 80% of the company&#8217;s business).</p>
<p><strong>Progress so far is hard to assess</strong></p>
<p>This is partly due to the recession itself, partly to DELL having to try to restructure the corporate house during an economic tornado.   I&#8217;m not sure how the reorganization is faring, but then I&#8217;m not an expert on DELL.  But I didn&#8217;t get the sense from listening to last week&#8217;s conference call that professional Wall Street tech analysts have a much better idea than I do.  So maybe lack of communication from DELL also plays a part.</p>
<p><strong>Do we as investors need to know?&#8230;probably not.</strong></p>
<p><strong></strong>In a case like this, the relevant investment question is:  do I need to know this information, or can I make a decision about the stock without it?  Here, my guess is it&#8217;s unlikely that we&#8217;ll get strong earnings acceleration from ongoing cost-cutting.   If anything, we may get further unusual losses.  So restructuring is probably a neutral or a mild negative.</p>
<p>Things probably can&#8217;t get any worse in the consumer business, since results are close to zero now and DELL seems determined to protect margins at the expense of incremental sales.  Public will go its own counter-cyclical way.   Half of small and medium business customers have already upgraded to Windows 7.</p>
<p>Therefore, the next big potential lift to earnings, I think, will come as and when enterprise customers start to buy new PCs again.  This is unlikely to happen before yearend&#8211;and possibly not before the middle of next year.  So my conclusion on DELL  is the best course of action is to watch and wait.</p>
<p><strong>One more post</strong></p>
<p><strong></strong>I have one more post to do on DELL&#8211;an analysis of its negative working capital situation and what constraints it potentially places on the company.  It will be out in the next day or two.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>I&#8217;ve completed a blog entry for every single day of this trip (over 100 now, crikey) before arriving here at Chez Haslam in St Jean d&#8217;Angely and my mild OCD/OPCD won&#8217;t let break that pattern when I&#8217;ve only a few more to go. The problem is I&#8217;m not really traveling per se, I&#8217;m just dropping in at my friend&#8217;s gaff to catch up and relax, that&#8217;s a bit of a problem for a travel diary.</p>
<p>So the entries until I depart for Paris on Saturday may (will) be somewhat more banal and mundane than usual, the silver lining they will also be much shorter.</p>
<p>When I get over to New Zealand (and beyond) there will be a much larger gap between posts (1 or 2 a week maybe) when stationed in one place and then when I&#8217;m on the move I&#8221;ll revert to the one a day plan that has served me since the beginning of April.</p>
<p>Today I&#8217;ve printed off my NZ visa, researched netbooks (<a href="http://www.amazon.co.uk/exec/obidos/ASIN/B002SSTVBQ/ref=ord_cart_shr?_encoding=UTF8&#38;m=A3P5ROKL5A1OLE">this</a> is looking likely), ate homemade chocolate and beetroot cake for lunch and homemade meatballs with spaghetti for tea, drank a little wine and beer and watched <a href="http://www.channel4.com/food/on-tv/come-dine-with-me/">&#8216;Come Dine With Me&#8217;</a> on the Channel 4 on demand web channel. It&#8217;s been all go really.</p>
<p>The photo is from somewhere between Madrid and Bilbao. Stop by this time tomorrow folks for another exciting entry of STBB.</p>

<p><strong>Mein Kommentar dazu</strong><br />
Wirklich ein tolles Gerät zu einem spitzen Preis. Auch die Bewertungen bei Amazon sind sehr positiv. Wer Windows 7 installieren möchte kann sich die Treiber wohl auch schon bei Samsung herunterladen. Wer ein 10,1“ Netbook sucht sollte hier zuschlagen.</p>
