<content:encoded><![CDATA[<div class='snap_preview'><p>So i have been reading a pretty cool book called &#8221; Snowcrash&#8221; wich is about a virus in the metaverse that causes hackers to completly loose there mind. Its not the metaverse as secondlife is now its way more advanced so its fun to read if your into scifi future kinda things. Its a book from Neal Stephenson thats is from 1992 so thats awesome that he then already had this kind off idea. More info see <a href="http://en.wikipedia.org/wiki/Snowcrash">http://en.wikipedia.org/wiki/Snowcrash</a></p>
<p>Two weeks ago i watched the movie Surrogates. Which reminded me a bit on Secondlife but instead having a avatar you have a realistic robot that you control walking around and not in a virtual world but in the real world. Ok so plot: In 2017, humans live in near-total isolation, rarely leaving the safety and comfort of their homes, thanks to remotely-controlled robotic bodies that serve as &#8220;surrogates,&#8221; designed as better-looking versions of their human operators. Because people are safe all the time, and damage done to a surrogate is not felt by its owner, it is a peaceful world free from fear, pain, and crime, or isnt it? hehe ok i wont say more because then it wont be fun if you stil want to see the movie. More info see <a href="http://en.wikipedia.org/wiki/Surrogates_(film)">http://en.wikipedia.org/wiki/Surrogatesa&#62;<br />

<description><![CDATA[Fuzzy recently opened a discussion (but not comments) comparing Second Life to Snow Crash. Here]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p>Fuzzy recently <a href="http://fuzzybuzz.wordpress.com/2009/06/01/linden-lab-needs-to-read-snow-crash-again">opened a discussion</a> (but not comments) comparing <a href="http://secondlife.com/">Second Life</a> to <a href="http://en.wikipedia.org/wiki/Snow_Crash">Snow Crash</a>. Here&#8217;s my comment, which may or may not pass moderation:</p>
<blockquote><p>I could not agree more about &#8216;Juanita&#8217;s faces&#8217; and think avatar improvements are long overdue. My personal favorite would be hand and finger joints and animations (so we could do amazing things like <a href="http://www.2ndfantasy.org/?p=750">this</a>), but that ain&#8217;t happenin&#8217; not with the focus on business over creativity. Those running Linden Labs seem to be sending a clear message that this ain&#8217;t your Philip&#8217;s SL anymore, for better or worse. To be fair, they have important things like making money to consider above making a toy for creatives to use, which in many ways is a backwards way to look at it (but that&#8217;s another discussion). The most frustrating argument to wage with any bottom-liner justifying SL, or any virtual world for business, is the importance of the avatar. Jaunita&#8217;s struggles for others to see that importance seem relevant more now than ever. But she did it anyway and everyone realized how key it was later. This is the same as business-types publicly denouncing the importance or relevance of avatar appearance only to secretly come to me or others and ask to help them with their hair/eyes/shape/clothes/shoes (and this has become a regular thing). Why can&#8217;t people just admit appearance and presence is core to any real collaborative, social activity&#8211;especially in a virtual world that focuses on immersion as the primary justification for 3D over 2D. Perhaps someday, until then, all we can do is play with what we have.</p></blockquote>
<p>I recommend to those that have not read SnowCrash or Neuromancer (and I have not read the latter, yet), to swallow hard and read them, to the end (not just enough to add hip pith to your presentations). I&#8217;ll bet a good 50% of current Linden Labs employees have not read either. I&#8217;d love to be wrong.</p>
<p>That said, I hated SnowCrash, deeply. Here&#8217;s my original review (<a href="http://slprofiles.com/secondlifeblog.asp?a=comments&#38;id=14519">reposted from SL profiles</a>, which I don&#8217;t use much these days):</p>
<blockquote><p>Ok, just finished reading <a href="http://en.wikipedia.org/wiki/Snow_Crash">Snowcrash</a>. Besides now understanding what everyone is talking about when they say that Neal Stephenson invented the terms &#8216;avatar&#8217; and &#8216;metaverse&#8217;, which he admits is not exactly true in the appendix (but I won&#8217;t spoil the surprise), besides that, and knowing why everyone wears a katana on their back, why you can&#8217;t be a Hero (name) in SL, and why everyone likes to make really fast motorcycles in SL, besides that, well, and besides the interesting tangent into Sumerian mythology, and the radically wonderful explanation of divergent languages (I do so love linguistics) and besides the really really really (yes that is three &#8216;really&#8217;s) cool plank that Y.T. rides with telescoping wheels, and the Aleutian ocean surfing Raven pulls off, and the dog-brained rat things, besides all that I just must say I didn&#8217;t like it overall.</p>
<p>It was not a shock to me to read in Neal&#8217;s comments that originally it was intended as a collaborative work with a graphic novelist but that just didn&#8217;t work out. Neal&#8217;s writing style is amazingly different, fresh and the way he narrates the thoughts of everything, even inanimate objects makes it fun. I particularly liked his description of what a cute doggy thinks after it&#8217;s been turned into a radio-isotope-driven rat thing (here&#8217;s a hint, it thinks the same things).</p>
<p>I just have to say for me it was anticlimactic and devoid of any real reason to care, in fact, after his description of one possible near future&#8211;everything franchulated (his word), loglo and toxic waste everywhere, everyone pumping guns or steroids, 15-year-olds sleeping with psychopathic killers who turn out to be just nice guys doing their jobs (woops, I gave that surprise away, sorry)&#8211;well I just found myself not caring if the villain succeeded in the first place. &#8220;So what if the world is destroyed, or whatever.&#8221; Plus it doesn&#8217;t resolve any of the real relationship possibilities that it could have. I really wanted to see Y.T. meet up with Uncle Enzo in the end. Nope. Characters are shallow, colored-in drawings more fitting to a comic or pop-movie screen ala Matrix. And for that reason I would still recommend it. It is like watching an R-rated thrill-ride movie without the movie.</p>
<p>At least I can say I read the thing unlike so many poser &#8216;metaverse-evangelists&#8217; out there referencing it without having a clue what they are talking about, or worse, making safe references to some Snowcrash-izm in front of a room of business people and a microphone that can&#8217;t question them on it so they can trick people into thinking they read it. You know who you are. Give Snow Crash a read. You can have mine. Just keep your expectations low and some f-bomb deodorizer around.</p></blockquote>
<p>It may turn out that SL or whatever the leading virtual world becomes will be devoid of these Snow Crash items. SL might not have advanced animations and other smoothness that Crysis and WoW have, but hey, you can build and script a rat-thing, which is still pretty cool. /me looks through his inventory for radio isotopes.</p>

<p>47.  Yellow Snowcrash</p>
<p>An outfit calling itself the iPhone Dev Team released a free piece of software called “yellowsnOw” that allows subscribers to use the device on any wireless network running the same technical standards. </p>
<p>Apple declined to comment on the new software. AT&#38;T says use of the unauthorized software would void the phone’s warranty, the Wall Street Journal reports. </p>

<content:encoded><![CDATA[<div class='snap_preview'><p>Good day followers,</p>
<p>Before I start todays post, I have a question to ask everyone who reads this blog.  Please leave a comment with your answer in it.</p>
<p>do you think the  i phone is good, or a regurgitated piece of crap pulled out of Steve Jobs&#8217; ass while he was going through a session with his proctologist?</p>
<div class="wp-caption aligncenter" style="width: 310px"><img class="alignnone" src="http://www.mp4converter.net/images/upload/iphone_home.gif" alt="" width="300" height="495" /><p class="wp-caption-text">It still has that black color it had when it was pulled out</p></div>
<p>On to today&#8217;s blog.</p>
<p>I know that this first topic isn&#8217;t really about media, but anyone who liked the matrix, sci-fi, and supreme randomness should read the book Snowcrash.  It is possibly one of the best books I have read in a long time.</p>
<p>In a nutshell, the book is about a man named Hiro Protagonist (no, I&#8217;m not kidding) who is a pizza delivery man in reality, and a samurai prince in a virtual world called the metaverse.  He eventually finds out about a virus which is killing people in the metaverse and reality, and has perform the cliche act of saving everyone. Also, the pizza delivery service is run by the maffia.</p>
<div class="wp-caption aligncenter" style="width: 486px"><img src="http://www.gardenal.org/trabalhosujo/snowcrash.jpg" alt="when you read this book, youll realize how hard it was for me to give a summary" width="476" height="800" /><p class="wp-caption-text">when you read this book, you&#39;ll realize how hard it was for me to give a summary</p></div>
<p>In other news, the new Silent Hill game will most probably be unavailable in Australia.  If you live in Australia: YOU CAN OFFICIALLY PROCLAIM THAT YOUR COUNTRY HAS GONE INSANE.  THEY SHOULD DO WHAT SEVERAL IDIOTS DO, AND LICK RAT TESTICLES DIPPED IN VINEGAR BECAUSE THEY ARE SO FUCKIN INSANE.  Why?  because your government has refused to give Silent Hill and ESRB rating.  Any game without an ESRB rating can&#8217;t be sold in stores there.  Its not so much your country&#8217;s fault as it is your government&#8217;s.</p>
<div class="wp-caption alignnone" style="width: 573px"><img src="http://www.megatonnews.com/wp-content/uploads/2007/09/silenthillgermanscan1.jpg" alt="" width="563" height="309" /><p class="wp-caption-text">ignore the german</p></div>
<p>And yes, I do have the power to insult an entire country</p>
<p>And yes, I do expect to hear from many angry Australians.  I simply can&#8217;t guarantee I&#8217;ll care.</p>
<p>Under normal circumstances, I wouldn&#8217;t be talking about the following topic, but I recieved a request from a friend (who doesn&#8217;t live in the basement I live in.  I do own a phone you know.), to dedicate part of my post to Street Fighter.  So I will.</p>
<p><em><strong>STREET FIGHTER</strong></em></p>
<p>Yes this game has been around for over a decade, and is still pumpin blood, despite that this blood is now pumped through a pacemaker.</p>
<p>This oldy but a goody has recently come out with yet another addition to the series, streetfighter 4.  and after 10 years, they finally decided to take the series to <span style="text-decoration:underline;"><strong>3D!!!!</strong></span> Most people won&#8217;t appreciate this new art style, but being a street fighter die-hard fan, I think I&#8217;ll still enjoy it.  But then again, anyone whos ever taken a liking to side scrolling fighter will always find at least one street fighter game they like.  Why? BECAUSE THERE ARE SOOOOOOOOOO FUCKING MANY!</p>
<div class="wp-caption alignnone" style="width: 592px"><img src="http://streetknowledge.files.wordpress.com/2008/02/streetfighter-ii_06abx.jpg?w=582&#038;h=450" alt="street fighter.  nothing else needs to be said." width="582" height="450" /><p class="wp-caption-text">street fighter.  nothing else needs to be said.</p></div>
<p>street fighter, street fighter 2, street fighter 2 turbo, super street fighter, street fighter turbo, street fighter 2 hyper fighting, street figher 2 turbo HD remix, street fighter alpha, street fighter alpha 2, street fighter 3, street fighter 3 second impact, and the list goes on, and on, and on.</p>
<p>but lets all admit that no one&#8217;s complaining.  Street fighter is possibly one of the best fighters made to date.  mainly because its one of the most original gems made to date.  In  what other game have you ever seen a fat man move at lightning speed?</p>
<div class="wp-caption aligncenter" style="width: 320px"><img src="http://www.rvgfanatic.com/mediac/400_0/media/DIR_593415/HondaSF4.JPG" alt="never again will you see a fat man move this fast" width="310" height="240" /><p class="wp-caption-text">never again will you see a fat man move this fast</p></div>
<p>I lead Grues, so let me lead you,</p>
<p><em>The Grue Leader</em></p>

<description><![CDATA[Es conocido desde hace tiempo que hay una vulnerabilidad de DoS (Denial of Service, Denegación de Se]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p>Es conocido desde hace tiempo que hay una vulnerabilidad de <a href="http://en.wikipedia.org/wiki/Denial-of-service_attack">DoS (Denial of Service, Denegación de Servicio)</a> que afecta a muchos UNIX (¿cuál es el plural de UNIX? <a href="http://jyte.com/cl/the-plural-of-unix-is-unices">UNICES</a> suena fatal <img src='http://s.wordpress.com/wp-includes/images/smilies/icon_biggrin.gif' alt=':-D' class='wp-smiley' /> ), así como en GNU/Linux. Con simplemente escribir este conjuro en una shell, terminamos por colgar el sistema:</p>
<p><code> <img src='http://s.wordpress.com/wp-includes/images/smilies/icon_sad.gif' alt=':(' class='wp-smiley' /> ){ :&#124;:&#38;};: </code></p>
<p>Menuda movida, ¿no? :-O</p>
<p>Lo primero de todo, ¿qué significa ese código? Bien, si sustituimos &#8220;:&#8221; por &#8220;función&#8221; e <a href="http://es.wikipedia.org/wiki/Indentaci%C3%B3n">indentamos</a> bien, se entiende mejor:</p>
<pre> <img src='http://s.wordpress.com/wp-includes/images/smilies/icon_sad.gif' alt=':(' class='wp-smiley' /> ){ :&#124;:&#38;};:

funcion () { funcion &#124; funcion &#38; }; funcion

funcion () {
  funcion &#124; funcion &#38;
};
funcion</pre>
<p>Es decir, primero definimos una función y luego la llamamos. Dentro de esa función, se llama de nuevo a esa función (<a href="http://es.wikipedia.org/wiki/Recursi%C3%B3n">recursión</a>) dos veces y se une esos dos procesos por una tubería (<a href="http://en.wikipedia.org/wiki/Pipeline_(Unix)">pipe</a>). Además se pone un &#38; al final para que todo eso se ejecute en segundo plano.</p>
<p>A fin de cuentas lo que tenemos es un proceso que se llama a sí mismo (lo que ocasiona un bucle), pero que no tiene condición de finalización (bucle infinito) y lanza dos procesos hijos cada vuelta del bucle y los une por una tubería (más del doble de recursos necesarios cada vez).</p>
<p>Lo dicho, esto es más viejo que el picor, aunque hay scripts realmente sencillos que hacen cosas parecidas con distinto código. En <a href="http://www.shuningbian.net/2005/05/defusing-bash-forkbomb-in-netbsd.php">Journey&#8217;s End</a> nos plantean uno:</p>
<p><code>#!/bin/sh<br />
$0 &#38;<br />
exec $0<br />
</code></p>
<p>Así que el problema no está en el conjuro en sí (no tendría sentido poner en nuestro IDS esa cadena para detectarla como maliciosa, porque habría infinitas cadenas que harían lo mismo), sino en la teoría que subyace: un usuario con un límite demasiado amplio de procesos de usuario creados, puede acabar los recursos del sistema.</p>
<p>¿Cuál es mi límite de procesos? Lo podemos conocer fácilmente con el comando ulimit:</p>
<p><code>ulimit -a<br />
core file size          (blocks, -c) 0<br />
data seg size           (kbytes, -d) unlimited<br />
scheduling priority             (-e) 0<br />
file size               (blocks, -f) unlimited<br />
pending signals                 (-i) 12273<br />
max locked memory       (kbytes, -l) 32<br />
max memory size         (kbytes, -m) unlimited<br />
open files                      (-n) 1024<br />
pipe size            (512 bytes, -p) 8<br />
POSIX message queues     (bytes, -q) 819200<br />
real-time priority              (-r) 0<br />
stack size              (kbytes, -s) 8192<br />
cpu time               (seconds, -t) unlimited<br />
max user processes              (-u) 12273<br />
virtual memory          (kbytes, -v) unlimited<br />
file locks                      (-x) unlimited<br />
</code></p>
<p>El número máximo en este sistema es 12273 para mi usuario, más que suficiente para dejarlo tuerto <img src='http://s.wordpress.com/wp-includes/images/smilies/icon_sad.gif' alt=':-(' class='wp-smiley' /> </p>
<p>Si quisiéramos evitar este problema, bastaría con cambiar ese límite, así:</p>
<p><code>ulimit -u 1000</code></p>
<p>De esta manera, evitamos el problema, aunque solamente para la shell en la que hemos ejecutado este comando. Podríamos lanzarlo en el /etc/profile o en algún script de inicio de sesión, pero es bastante más elegante <a href="http://www.cyberciti.biz/tips/linux-limiting-user-process.html">modificarlo en el fichero limits.conf</a>.</p>
<p><code>grep "nproc" /etc/security/limits.conf<br />
#        - nproc - max number of processes<br />
#@student        hard    nproc           20<br />
#@faculty        soft    nproc           20<br />
#@faculty        hard    nproc           50<br />
#ftp             hard    nproc           0<br />
</code></p>
<p>Como vemos, tenemos varios ejemplos que limitan los procesos a 20 o a 50 en función del grupo al que pertenezcan. También se pueden definir límites por usuario o se puede establecer un límite general:</p>
<p><code>% hard nproc 1000</code></p>
<p>Con esto limitamos el número máximo de procesos a 1000 para todos los usuarios.</p>
<p>Y entonces podemos preguntarnos ¿cómo la gente de GNU/Linux es tan torpe de poner un límite que nos puede colgar el sistema operativo? La respuesta tiene que ver no solo con la cantidad de procesos, sino con el peso de cada uno de ellos. Si fijamos a 1000 el número máximo de procesos por usuario, nos libramos de las dos bombas fork que hemos visto, pero modificando ligeramente la segunda, podríamos seguir tirando el sistema para muchos menos procesos:</p>
<p><code>#!/bin/sh<br />
$0 &#38;<br />
find . &#38;<br />
exec $0<br />
</code></p>
<p>Quizá entonces no solamente haya que limitar el número de procesos, sino <a href="http://www.cyberciti.biz/tips/linux-limiting-user-process.html">otros límites definidos en el fichero limits.conf</a>.</p>
<p>Cuando leamos que tal <em>malware</em> permite ejecutar <em>&#8220;código arbitrario&#8221;</em> en nuestro sistema, nos podremos acordar de este torpe código y de cómo el solito es capaz de tumbar todo el servidor, desde una cuenta de usuario :-O</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>There is a neat post on <a href="http://mashable.com/2008/05/21/smallworld/">Mashable</a> about the virtual online world <a href="http://www.smallworlds.com/">SmallWorlds</a>:</p>
<p>&#8220;SmallWorlds is a new web-based virtual world offering that is looking to combine several aspects of current trends, with a great focus on social media. So you can use Flickr images as posters in your virtual bedroom, or watch YouTube clips on your 3D living room television.</p>
<p>Other applications, like Grafiti, that have become popular on networks like Facebook, are also present in SmallWorlds. Games, such as pool, can also be played within SmallWorlds, in a similar fashion as gameplay on a portal like Yahoo Games. &#8220;</p>
<p>This feels like another step toward the kind of online worlds envisioned in books like SNOW CRASH and NEUROMANCER where all the elements of your online life are sythesized into an actual environment that moves away from &#8220;pages&#8221; and &#8220;links&#8221; and incorporates everything from your email to your videos to your calendar.</p>
<p>By allowing you to pull in existing sites, SmallWorlds doesn&#8217;t force you to rebuild your &#8220;life&#8221; from scratch as you sort of have to do in SecondLife.</p>
<p>Not sure this will be wildly popular since these worlds still feel slower than just accessing the net directly but there is clearly interest in finding &#8220;skins&#8221; to place over the feed so that it all becomes a bit more familiar and, well, homey.</p>

<description><![CDATA[Metaverso es un término que se utilizó por primera vez en la novela Snow Crash, de Neal Stephenson, ]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p style="text-decoration:none;text-align:justify;"><span style="font-style:normal;"><span style="text-decoration:none;"><span>Metaverso es un término que se utilizó por primera vez en la novela </span></span></span><em><span style="text-decoration:none;"><span>Snow Crash</span></span></em><span style="font-style:normal;"><span style="text-decoration:none;"><span>, de </span></span></span><em><span style="text-decoration:none;"><span>Neal Stephenson</span></span></em><span style="font-style:normal;"><span style="text-decoration:none;"><span>, en 1992. Según sus propias palabras, dadas las limitaciones que encontró en el término &#8216;realidad virtual&#8217;, decidió crear un nuevo término para expresar la idea que tenía en mente: entornos en los que los humanos interactúan social y económicamente como iconos en un espacio virtual, que actúa como metáfora del mundo real, pero eliminando las limitaciones físicas.</span></span></span></p>
<p style="text-decoration:none;text-align:center;"><img class="aligncenter" src="http://upload.wikimedia.org/wikipedia/en/d/d5/Snowcrash.jpg" alt="" width="119" height="200" /></p>
<p style="margin-bottom:0;font-style:normal;text-decoration:none;text-align:justify;">Son 3 las <strong>características</strong> que debe cumplir un metaverso:</p>
<p style="margin-bottom:0;font-style:normal;text-decoration:none;text-align:justify;">-Interactividad: Mundo compartido, en el que las acciones de un usuario pueden ser percibidas e influir en el resto de los usuarios.</p>
<p style="margin-bottom:0;font-style:normal;text-decoration:none;text-align:justify;">-Corporeidad: Debe ser un entorno simulado en primera persona, sujeto a ciertas leyes de la física, y con recursos limitados.</p>
<p style="margin-bottom:0;font-style:normal;text-decoration:none;text-align:justify;">-Persistencia: El programa persiste a pesar de que no halla usuarios conectados. Se recuerdan las posiciones de usuarios y objetos.</p>
<p style="margin-bottom:0;text-align:justify;">
<p style="margin-bottom:0;font-style:normal;text-decoration:none;text-align:justify;">Y 4 los <strong>tipos</strong> de metaversos que nos podemos encontrar:</p>
<p style="margin-bottom:0;text-align:justify;">
<p style="margin-bottom:0;font-style:normal;text-decoration:none;text-align:justify;">-Juegos y mundos virtuales: Es aquí donde encontramos ejemplos como Second Life, o WoW</p>
<p style="margin-bottom:0;font-style:normal;text-decoration:none;text-align:justify;">-Mundos espejo: Es el ejemplo de Google Earth.</p>
<p style="margin-bottom:0;font-style:normal;text-decoration:none;text-align:justify;">-Realidad aumentada: Aplicación de mundos espejo a situaciones reales para mejorar la vida, (consulta de Google Earth en una PDA).</p>
<p style="margin-bottom:0;font-style:normal;text-decoration:none;text-align:justify;">-Lifelogging: Seguimiento del día a día, como cuentakilometros en las zapatillas de correr, etc.</p>
<p style="margin-bottom:0;text-align:justify;">
<p style="margin-bottom:0;text-align:justify;"><span style="text-decoration:none;">Está claro entonces que Second Life cumple con creces todas las características de un metaverso. Se trata de un espacio virtual en el cual los usuarios, haciendo uso de su ordenador, se relacionan socialmente, viajan de unas islas a otras, e interactuan económicamente, mediante la producción y consumo continuos de servicios. Es destacable en este caso la conexión entre el plano real y virtual, mediante el posible cambio entre Linden$ y dólares reales. Por tanto ya no solo se trata de un mundo paralelo y aislado, sino que la economía, los problemas, la política y sociedad </span><span style="text-decoration:none;"><em>real,</em></span><span style="text-decoration:none;"><span style="font-style:normal;">se ve reflejada en SL. A veces ocurre hasta tal punto, que algunos usuarios se encuentran desencantados cuando observan que existe en ocasiones un parecido demasiado fiel al mundo real, cuando lo que buscan es una evasión del mismo, una alternativa mejor a una vida con la que no están del todo agusto. Así como en el mundo real no puedes elegir la proyección que los demás ven de tu propio yo, en el metaverso es posible mostrarse tal como se quiere ser, y no tal como se es. (Caso en la novela del protagonista, repartidor de pizza en la realidad, y principe guerrero en el metaverso). La polémica que todo esto genera, es la cuestión sobre la adaptación social de algunos usuarios al mundo real, y de si realmente este tipo de tecnología les ayuda a sentirse socialmente reconocidos, o si por el contrario les aisla aun más, incapacitandolos aún más para la vida cotidiana.</span></span></p>
<p style="margin-bottom:0;text-align:justify;">Un ejemplo más del uso de la idea del metaverso, es la película Matrix. Una creación a imagen y semejanza del mundo en el que actualmente vivimos, pero totalmente virtual. En este caso, el objetivo de semejante mundo es tener a los humanos bajo control, sin que estos tengan la sensación de estar presos bajo el dominio de las máquinas. Esto se traduce en una forma ideal de <em>evitar una revolución</em> por su parte, y mientras tanto obtener de sus cuerpos la energía que las máquinas necesitan. Se trata de una visión catastrófica de las consecuencias de la inmersión absoluta del ser humano en el metaverso. Hay quien compara el argumento de la película con el famoso &#8220;mito de la caverna&#8221; de Platón, pero mejor lo vemos en un video:</p>

<description><![CDATA[      “Nel mondo reale &#8211; sul pianeta Terra, nella Realtà, abitano tra i sei e i dieci miliardi]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;"><span style="font-family:Georgia;font-size:16px;line-height:20px;" class="Apple-style-span"><img src="http://kingdomofink.files.wordpress.com/2008/03/152d91f1612ff7884a4a1eabb0740e0f.thumbnail.jpg" alt="152d91f1612ff7884a4a1eabb0740e0f.jpg" /><span style="font-family:'Times New Roman';font-size:12px;line-height:normal;" class="Apple-style-span">      “Nel mondo reale &#8211; sul pianeta Terra, nella Realtà, abitano tra i sei e i dieci miliardi di persone. In qualsiasi momento le si osservi, si vedrà che la maggior parte di loro è intenta a costruire mattoni d’argilla e a lubrificare i propri AK-47. Circa un miliardo di persone ha abbastanza soldi per comprarsi un computer. Di questo miliardo di potenziali possessori di computer, forse solo un quarto se lo compra veramente, e solo un quarto di questi ultimi ha macchine abbastanza potenti da gestire il protocollo della Strada. Ciò significa che, in qualsiasi momento, circa sessanta milioni di persone possono accedere alla Strada. Se a queste ne aggiungiamo altri sessanta milioni che non se lo potrebbero permettere, ma che ci vanno lo stesso, usando computer pubblici o quelli della propria scuola o del proprio ufficio, si può concludere che, mediamente, la Strada è occupata da un numero di persone pari al doppio della popolazione di New York.” </span></span></p>
<p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;">La Strada di cui parliamo percorre e taglia in due lungo la linea dell’equatore il Metaverso, un’invenzione letteraria, creata da Neal Stephenson in “Snow Crash” nel ‘92. Il Metaverso viene descritto dallo scrittore americano come una sorta di realtà virtuale condivisa tramite internet dove si è rappresentati in tre dimensioni attraverso il proprio Avatar. Nel Metaverso ogni persona può, pagando, realizzare in 3D ciò che desidera, negozi, uffici, night club, musei e ogni altra cosa che sarà poi visitata dagli utenti. </p>
<p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;">A quindici anni di distanza, anno domini 2007, la popolazione mondiale non è proprio di dieci miliardi, anche se una parte di essa è intenta a lubrificare Kalasnicov o a costruire mattoni di argilla, New York non è poi così densamente popolata, la “Strada” non esiste, ma il Metaverso sì, ed è frequentato da sette milioni di persone. Già perché, Neal Stephenson, narrando le imprese dell’ultimo hacker free lance, Hiro Protagonsit, ha praticamente descritto Second Life. </p>
<p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;">Second Life è una comunità virtuale, una chat tridimensionale, creata nel 2003 dalla Linden Lab che nel giro di pochi anni ha visto centuplicare il numero dei suoi cittadini residenti. La chiave del successo di Second Life è la stessa che la distingue dai giochi di massa online e cioè che ogni personaggio corrisponde a un giocatore reale, a un utente connesso e non a un personaggio creato dal sistema. Gli incontri all&#8217;interno del mondo virtuale si configurano dunque come reali scambi tra esseri umani attraverso la mediazione figurata degli avatar. C’è già chi ritiene che la seconda vita rappresenti il futuro dei computer, che smetteranno di avere un desktop a interfaccia grafica (icone, cartelle, finestre ecc.) e inizieranno ad avere un’interfaccia 3D simile a Second Life. </p>
<p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;">Il primo passo in questa direzione è stato fatto da poche settimane. La Linden Lab infatti ha già messo in circolazione la versione di prova di Second Life Voice. In pratica, con un cuffia e un microfono, si può dare voce al proprio Avatar che reagisce visivamente al tono della voce mostrando all’interlocutore una serie di espressioni o di gesti calibrati sulle “emozioni vocali” della propria controparte reale. Se fino a qualche mese fa bisognava limitarsi a chattare con gli altri avatar o complicarsi la vita attraverso l’uso dello streaming ora con l’arrivo della voce il primo vero passo verso il Metaverso stephensoniano è stato fatto. Quando potremmo entrare in Second Life in prima persona (nel romanzo avviene attraverso degli occhiali e delle tute speciali) il computer come lo consociamo sarà puro vecchiume. </p>
<p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;">Sul Metaverso della Linden Lab si è scritto di tutto e di più. Le edicole e le librerie cominciano a far apparire sui loro scaffali e ripiani volumi e volumetti dedicati alla seconda vita. “ISBN”, per esempio, ha pubblicato in questi giorni “Second life. Guida turistica essenziale” di Carr e Pond, un libro curioso che si discosta dalla produzioni in materia con un taglio quasi da guida della “lonley planet” o della “rough guide”.</p>
<p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;">Come ogni innovazione Second Life ha i suoi accaniti detrattori e i suoi fanatici ammiratori, e come ogni cosa ha i suoi lati positivi e negativi. Al di là dei fenomeni di costume che fanno notizia come sesso, criminalità (supereroi che la combattono) e gossip &#8211; tutto rigorosamente virtuale &#8211; l’uso che si può fare di questa piattaforma tridimensionale ha anche un risvolto interessante dal punto di vista culturale. È possibile visitare diversi musei e gallerie d’arte, assistere a presentazioni di libri, concerti, frequentare lezioni e seminari a distanza, infilarsi tra le librerie di biblioteche da cui è possibile scaricare i file di libri in copyleft (permesso d’autore) o con i diritti scaduti. Anche solo girovagando nella parte italiana del Metaverso ci si imbatte in iniziative e luoghi interessanti (basta cercarli nell’apposita finestra dell’interfaccia e teleportarsi) come la “GridGallery”, la “Biblioteca Archimedica”, il “Delos Book Club”, la splendida mostra multimediale sui diritti umani in concomitanza con la pubblicazione dell’opera “Diritti umani” (UTET &#8211; De Agostini) o sul versante ludico, il Korova Milk Bar, replica esatta di quello del film “Arancia Meccanica” e così via. Anche il Ministero degli Affari Esteri, ha aperto in via sperimentale un Istituto Italiano di Cultura all&#8217;interno di Second Life, suscitando perplessità e polemiche sull’utilità e sui costi di un’operazione simile, che secondo i promotori dell’iniziativa servirà a “dare nuovo slancio alla promozione della creatività italiana soprattutto nei settori dell&#8217;arte contemporanea, del design, dell&#8217;architettura e del patrimonio culturale.” Certo, se un paese oculato e attento come la Svezia ha aperto un proprio consolato in Second Life qualche ragione valida dovrà pur esserci.</p>
<p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;">In effetti è difficile spiegare a chi non è abituato a usare il computer a 360 gradi, il motivo per cui sette milioni di persone vivano una seconda vita evitando di cadere nella trappola dello psicologismo o della sociologia; e ancor più difficile spiegare a chi non ha ben capito “cosa diavolo” sia Second Life, il perché qualcuno sia disposto a pagare soldi veri in cambio di case, isole, vestiti, automobili, tappeti volanti&#8230; finti. La seconda vita ha una sua economia, con le sue regole di mercato e il suo mondo del lavoro. A differenza del mondo reale però, spesso per fare i soldi bisogna essere capaci di fare qualcosa. La bravura, l’ingegno e la fantasia pagano, e non importa se anche grandi aziende, immobiliari, finanziarie, multinazionali si affacciano sul Metaverso, perché per riuscirci hanno bisogno di persone che sappiano farlo e non è sempre detto che le seconde abbiano bisogno delle prime.</p>
<p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;">“Snow Crash”, pubblicato in Italia per la prima volta da “Shake” nel ’95, è ora in <i>rotativa</i> per “Rizzoli” &#8211; che detiene i diritti anche di “Cryptonomicon” e della trilogia del “Ciclo Barocco” (di cui i letto<br />
ri stanno aspettando da troppo tempo il terzo volume) &#8211; forse proprio grazie alle popolarità crescente del Metaverso della Linden Lab. Stehpenson ha riplasmato e riscritto le regole di un genere che sembrava sul punto di capitolare: il cyberpunk. Prima di lui gli autori del filone si erano limitati a esplorare le coordinare dettate da Gibson e Dick. A lungo andare inevitabilmente la narrativa cyberpunk ha mostrato la corda e perso l’eccezionale spinta innovatrice e rivoluzionaria inscritta nel suo DNA di partenza. Neal Stephenson è riuscito a rianimare il cadavere insufflando nei suoi polmoni un elemento più potente dell’adrenalina: l’ironia. </p>
<p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;">Il Metaverso di “Snow Crash” è simile a Second Life e la vita che conducono i protagonisti del libro è simile alla nostra. La differenza sta nell’iperbole che porta Stephenson a dipingere un futuro in cui gli stati nazionali si sono sbriciolati diventando quartieri in franchising di proprietà di multinazionali (tra cui spicca la mafia). Hiro Protagonist, il protagonista per l’appunto, vive in un container, “un’unità di 7 x 10 metri in un D-Posit” in cui ci sono migliaia di container (anche più piccoli) adibiti a uso abitativo. A Hiro non importa, perché una volta connesso e inforcati gli occhiali, si ritrova nel Metaverso a vivere la sua seconda vita come “il più grande guerriero di spada del mondo”. Ma qualcosa non va. Qualcuno sta seminando il panico diffondendo un virus letale per Avatar e persone reali, lo “Snow Crash”. </p>
<p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;">Un libro, ipercinetico, folle, avventuroso e dotato di catastrofico senso dell’umorismo. Un libro che con quindici anni di anticipo ha descritto Second Life e che forse, con trenta, lo ha fatto con il mondo intero.</p>
<p style="font:normal normal normal 12px/normal 'Times New Roman';margin:0;"> </p>

<content:encoded><![CDATA[<div class='snap_preview'><p>I&#8217;ve been a fan of what is most commonly called &#8220;CyberPunk&#8221; since I read <a href="http://www.williamgibsonbooks.com/">William Gibson</a>&#8217;s <a href="http://en.wikipedia.org/wiki/Neuromancer">Neuromancer</a> as a middle-schooler in the 80&#8217;s. I&#8217;d soon have my very first modem (1200 baud) hooked up to my Atari 800 allowing me access to what would become <a href="http://www.google.com/url?sa=t&#38;ct=res&#38;cd=2&#38;url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FAl_Gore&#38;ei=uEueR6zKDJvMeNnN5M0G&#38;usg=AFQjCNFQgqjQCcygchgcZvuz_H2EQxrsBg&#38;sig2=3_A9GsXUg-joQ8KPkxkjBQ">THE INTERNET</a> but wasn&#8217;t called that yet.  Mostly, I logged into a chatroom hosted at Dartmouth College &#8211; an early hub of the net and my hometown at the time.  By the time I read <a href="http://en.wikipedia.org/wiki/Neal_Stephenson">Neal Stephenson</a>&#8217;s <a href="http://en.wikipedia.org/wiki/Snow_Crash">Snow Crash</a> I was dreaming of a day when those crazy ideas would be a reality &#8211; perhaps not in my lifetime, but someday.</p>
<p>Instead, here we are with SecondLife, that, though a bit laughed at by the media at large, is an amazing realization of Stephenson&#8217;s futuristic vision &#8211; and it only took 20ish years from outlandish science fiction to reality (or virtual reality).  That&#8217;s just plain awesome.</p>
<p>Now, I realize this isn&#8217;t a news flash but it leads me to my point that reading near-future sci-fi is one of the ways I continue to keep my head in the game and, whenever possible, ahead of the curve.  The time-gap between these outlandish ideas and complete realization seems to me to be shrinking dramatically.</p>
<p>Once case is point to watch is a trend I have noticed in two recent releases, Gibson&#8217;s latest (and sadly not greatest) <a href="http://en.wikipedia.org/wiki/Spook_Country">Spook Country</a> and <a href="http://en.wikipedia.org/wiki/Vernor_Vinge">Vernor Vinge</a>&#8217;s recent <a href="http://en.wikipedia.org/wiki/Rainbows_End">Rainbows End</a>.  Both novels, set only 20 years into the future and written quite  recently both take the current notion of GoogleMap layers and related tech and bring into the world of realtime overlaying of the world around us via optics  (implanted in Vinge and via headgear in Gibson) to give the viewer a completely personalized realtime world view.  Whether this is selective data-tagging or actually laying a fantasy vision over the reality, the potential uses and implications really gets the mind spinning.</p>
<p>While I just don&#8217;t think we&#8217;re going to be living on Mars anytime soon (like so much sci-fi seems to hope) but I do think we will all be choosing exactly how the world looks to us in much the same way we currently chose skins for our homepage.</p>

<description><![CDATA[Estos días de fiesta de los Reyes Magos me han venido genial para darle un empujon a este mi primer ]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p>Estos días de fiesta de los Reyes Magos me han venido genial para darle un empujon a este mi primer libro de la lista.</p>
<p>Como novela Ciberpunk es bastante interesante y entrentenida. He leido otras críticas en las que se dice que es mejor (mucho mejor) que Neuromante.  Yo no estoy de acuerdo, desde luego Stephenson es mucho mas tecnologo que William Gibson, pero no tiene la poesia de este.</p>
<p>Como me gusta la descripción del argumento que da la wikipedia y hoy, lunes putativo estoy muy vago lo copio y pego sin mas.</p>
<p>&#8220;La novela narra la historia de <b>Hiroaki <i>Hiro</i> Protagonista</b>, un repartidor de pizza en el mundo real, pero príncipe guerrero en el <b>Metaverso</b>, que un buen día está a punto de no entregar una pizza a tiempo, motivo por el cual conoce a <b>T.A.</b>, una adolescente patinadora que hace pequeños trabajos de servicio postal. Poco después, Hiro descubre la existencia de un poderoso virus informático en el Metaverso que proyecta una imagen de ruido constante sobre un monitor y que afecta a la capacidad del lenguaje del individuo que contemple dicha imágen. Atando cabos, comenzará a descubrir que detrás de todo esto hay un conocido delincuente apodado <b>Cuervo</b> y una serie de mitos y leyendas relativos a <i>Babilonia</i>.&#8221;</p>
<p>Como ya he dicho, interesante&#8230; si te gusta la ciencia ficción. Si no es así, mantente apartado de esta novela o solo leerás cosas que te parecerán incongruentes.</p>
