Or: The state of Linux Graphics with Raspberry Pi and Rust
I have long wanted to create my own desktop operating system targeting the Raspberry Pi. I believe we should have a hackable desktop environment that is both powerful and lightweight, similar to BeOS and the Amiga. To build this desktop we really need full control over how apps draw to the screen, but still have hardware acceleration. That means we'll need to use real graphics drivers and real graphics APIs from existing Linux desktops. When I last looked at all things Linux graphics five years ago everything was a mess but with some promising signs. Over the past couple of days I've been researching the current state. Here is my report, with both good and bad news.
Improved Easing Functions
March 1st, 2013
Animation is just moving something over time. The rate at which the something moves is defined by a function called an easing equation or interpolation function. It is these equations which make something move slowly at the start and speed up, or slow down near the end. These equations give animation a more life like feel. The most common set of easing equations come from Robert Penner's book and webpage.
HTML Canvas Deep Dive: Updated and Free
July 17th, 2012
This week at OSCON gave an updated version of my 3 hour Canvas tutorial. I think the session was well received. It was one of only a few tutorials that was completely sold out, 200 seats taken. But if you couldn't be one of those two hundred I don't want you to miss out.
Read me in .net Magazine
March 27th, 2012
Thanks to my HTML Canvas Deep Dive at OSCON, .net Magazine asked me to write a tutorial for them. The topic was just something interesting with Canvas. I'm a huge fan of infographics, as well as .net Magazine, so I jumped at the chance to write for them. I recently discovered an amazing treasure trove of data at the World dataBank, so that formed the core of the article.
Java + SDL + Avian + webOS = Magically Delicious
August 31st, 2011
Mmmwaa haa haa. It lives! I've gotten Java to run on webOS natively with a new set of Java SDL bindings. That means it just *might* time to start a new project. Read on for how it works and how you could help.
Playing with Noise
May 12th, 2011
While I have many projects in progress right now, including Amino, Leonardo, getting the TouchPad out the door, and having my first baby (only a few weeks left!); every now and then I just get something into my head and have to code it out. Last night it was noise functions.
