Las opciones para reemplazar programas locales con alternativas en línea son cada vez más amplias. Algunas webapps ya no tienen nada que envidiarle a sus hermanas offline, y pueden sacarnos de un apuro en cualquier momento, o transformarse en una solución permanente. Así… » neoteo.com | neoteo.com

Over the years, I’ve had the pleasure of hacking on the frontend code for a bunch of xkcd’s interactive comics, including: unixkcd, xk3d, Umwelt, Time, Externalities, and Lorenz. This weekend, I was pinged about making something to coincide with the release of What If?: Serious Scientific Answers to Absurd Hypothetical Questions. The process of building ”Pixels” was even crazier than our usual April Fools rush, and had the extra intrigue of being live during Randall Munroe’s Colbert Report interview. Here’s a few anecdotes from the development of Pixels and a quick explanation of how it works. I hadn’t worked with some of the graphics programming patterns (coordinate systems!) for a while, so I ended up making some classic mistakes – hopefully you can avoid repeating them. :) ...

The roots of CGI lie in the first mechanical aids to drawing and painting. The earliest of these were developed to help solve a problem every artist has found to be sticky: perspective. Before the introduction of geometric perspective, the realistic depiction of nature was not one of the purposes of art. Instead, artists chose the size and position of objects in a picture by their relative importance to one another. A distant castle might appear to be larger than one in the foreground simply because it was considered more important. ...

Since 2004, I’ve owned a ThinkPad A22m - a laptop that came out in 2001. Much to the dismay of certain friends, I still feel no need to purchase a newer computer. I’ve often said that this old hardware can do everything I need while still letting me run modern software. However, it now seems like I will have to take some responsibility for the code if I want that to still be true in the future. Specifically, I am talking about open source ATI drivers on GNU / Linux. The four main video card lines released by ATI (now owned by AMD) have been Wonder, Mach, Rage and Radeon. I don’t think Wonder cards have any features that would warrant the development of a dedicated driver but Linux drivers for the other three have been written. The Radeon driver is actively maintained by software engineers at AMD and some people who work for other software companies. The other two? Not so much. The Rage 128 driver was especially in need of a major update recently. And since my computer has a Rage Mobility graphics card, I felt motivated to start working on the code even though I had never hacked such a low-level piece of software before. Since the effort has largely succeeded, I would like to share my experiences with editing an open source video driver. The learning curve was quite steep and when I first started reading documentation, it seemed like it was written for a different audience. This post is going to be an unadultered attempt to get a completely new reader to catch on to what I did. I’m sure I will later find out that many things written in this post are technically incorrect, but I will not edit them. I want the only knowledge communicated in this piece to be the knowledge that one might reasonably be expected to have after jumping into driver development for the first time. ...

This is an introductory overview post for the Linux Graphics Stack, and how it currently all fits together. I initially wrote it for myself after having conversations with people like Owen Taylor, Ray Strode and Adam Jackson about this stack. I had to go back to them every month or so and learn the stuff from the ground up all over again, as I had forgotten every single piece. I asked them for a good high-level overview document so I could stop bothering them. They didn’t know of any. I started this one. It has been reviewed by Adam Jackson and David Airlie, both of whom work on this exact stack. ...
