Por ahora, la Raspberry Pi viene sin carcasa, por lo que no sólo hay opciones comerciales, sino que la comunidad ha tenido ideas muy creativas: [1], [2] y [3]. Entre todas las opciones, la de imprimir tu propia carcasa me ha llamado la atención. Es sencilla, rápida de hacer y, sobre todo, incluye un plano. Utilizando este plano como base, hemos fabricado una carcasa en madera de contrachapado de 3mm. Las dimensiones del plano encajan en la Raspberry Pi como anillo al dedo. Lo único que hemos tenido que tener en cuenta es el grosor de la madera para las piezas laterales: ...

Si queremos añadir un enlace que nos permita saltar a una entrada aleatoria de un blog en WordPress, basta crear un archivo que contenga lo siguiente: <?php require('wp-blog-header.php'); query_posts(array('orderby' => 'rand', 'showposts' => 1)); if (have_posts()) : the_post(); $url = get_permalink($post->id); header("Location: " . $url); endif; wp_reset_query(); ?> Guardamos el archivo en una ruta accesible, por ejemplo en la raíz del blog. Sólo queda añadir el enlace para que nos lleve a una entrada aleatoria. ...

As a result of a long sequence of coincidences I entered the programming profession officially on the first spring morning of 1952 and as far as I have been able to trace, I was the first Dutchman to do so in my country. In retrospect the most amazing thing was the slowness with which, at least in my part of the world, the programming profession emerged, a slowness which is now hard to believe. But I am grateful for two vivid recollections from that period that establish that slowness beyond any doubt. ...

I regularly receive e-mail from people who want advice on how to learn more about computer security, either as a course of study in college or as an IT person considering it as a career choice. First, know that there are many subspecialties in computer security. You can be an expert in keeping systems from being hacked, or in creating unhackable software. You can be an expert in finding security problems in software, or in networks. You can be an expert in viruses, or policies, or cryptography. There are many, many opportunities for many different skill sets. You don’t have to be a coder to be a security expert. ...

Muchos de nosotros somos auténticos gamers en Android, y como buenos jugones, nos encantan los juegos de vieja escuela. Sí, ya sabéis, los clásicos: Mario Kart, Super Mario 64, cualquier juego de la Nes/Snes, etc¦ Y digo yo, con estos auténticas bestias de Android que tenemos, ¿no deberíamos poder jugar a todos ellos? Pues efectivamente, se puede. El único problema es que por razón X, a Google no le gusta mucho que hayan emuladores en el Play Store y por ello se encuentran tan pocos. Pero tranquilos que hoy os traemos una recopilación de todos los emuladores actuales a los que se puede jugar en Android ...

Ok, perhaps I jest. As a Python instructor, understanding decorators is a topic I find students consistently struggle with upon first exposure. That’s because decorators are hard to understand! Getting decorators requires understanding several functional programming concepts as well as feeling comfortable with some unique features of Python’s function definition and function calling syntax. _Using_ decorators is easy (see Section 10)! But writing them can be complicated. I can’t make decorators easy - but maybe by walking through each piece of the puzzle one step at a time I can help you feel more confident in understanding decorators[1]. Because decorators are complex this is going to be a long article - but stick with it! I promise to make each piece as simple as possible - and if you understand each piece, you’ll understand how decorators work! I’m trying to assume minimal Python knowledge but this will probably be most helpful to people who have at least a casual working exposure to Python. ...

Nick is building a universe on his computer. He’s already mapped out his first planet: an anvil-shaped world called Denthaim that is home to gnomes and gods, along with a three-gendered race known as kiman. As he tells me about his universe, Nick looks up at the ceiling, humming fragments of a melody over and over. ”I’m thinking of making magic a form of quantum physics, but I haven’t decided yet, actually,” he explains. The music of his speech is pitched high, alternately poetic and pedantic - as if the soul of an Oxford don has been awkwardly reincarnated in the body of a chubby, rosy-cheeked boy from Silicon Valley. Nick is 11 years old. ...

Autism may be associated with mathematical skills. Autism researcher Simon Baron-Cohen has published studies that autism is more prevalent in the familes of physicists, engineers, and mathematicians. Unusual mathematical skills are reported in a small percentage of cases of ”classic autism.” Movies, television, and popular culture such as Rainman (1988), Mercury Rising (1998), and many other works often play up this rare association by presenting autistic characters with extreme mathematical abilities. ...

Lazy sysadmin is the best sysadmin –Anonymous System administrators job is not visible to other IT groups or end-users. Mostly they look at administrators and wonder why sysadmins don’t seem to have any work. If you see a sysadmin who is always running around, and trying to put down fire, and constantly dealing with production issues, you might think he is working very hard, and really doing his job. But in reality he is not really doing his job. ...
