geeky stuff from a geeky man
Came across this great graph outlining some interesting facts around Open Source. Original article was called "Should Open Source Be An Enemy Of The State?" and is itself a good article discussing some of the paradox around recent suggestion made is US policies and Open Source.

Sony Pictures Imageworks, the award-winning visual effects and digital character animation unit of Sony Pictures Digital Productions, released the Alpha version of its source code for OSL, its Open Shading Language, it was announced today by Rob Bredow, Chief Technology Officer of Sony Pictures Imageworks.OSL is a fundamentally different approach to shader languages for visual effects and computer animation rendering. OSL was designed to enable and support the latest developments in rendering technology. Unlike previous shader languages, OSL assumes a rendering system that can perform ray tracing, and provides for natural global illumination and a demand for physical accuracy. All of which is significantly different from the assumptions made years ago when most of the current shader languages were first developed.Sony Pictures Imageworks initially developed OSL for use with its in-house renderer in the production of animated feature films and visual effects. The language specification released today was developed with input by other visual effects and animation studios, including Rhythm & Hues, who also wish to use it. The code is now available through Imageworks’ Open Source website at http://opensource.imageworks.com/
Imageworks announced its Open Source program last August and has spent the past several months preparing OSL for use on its upcoming films.
This early release of code follows the model of the most successful open source programs in which development from this point forward will be done “in the open” for others to watch, use and contribute to as desired. OSL is licensed under a “production friendly” open source license. Imageworks is optimistic that OSL will be adopted broadly by those needing a modern shading language for production needs.
“We’re excited to be sharing OSL with the world,” said Rob Bredow. “Our goal is to follow the model of the most successful open source software by making our development public. This provides the very best opportunities for collaboration and adoption. Even though it’s in its early stages, there is a lot of sophisticated groundwork already laid in OSL. We look forward to the response from the computer graphics community”
OSL TAKES A DIFFERENT APPROACH
According to Imageworks’ OSL lead developer Larry Gritz, one of the industry’s foremost experts in shading and rendering, shaders in other languages compute the color of an object as viewed from a particular direction. In this way, the shader is a black box to the renderer — all the renderer can do is execute the shader, for a particular direction, and get the result.
What distinguishes OSL from prior languages is that the material properties of surfaces, explicit descriptions of how light is scattered by them, are treated as a first-class concept that the shaders compute and that the renderer can then manipulate and reason about. The renderer can evaluate these properties, i.e., figure out the outgoing radiance in any particular direction. This is just one of many things OSL can do. It also “importance samples” these surfaces, which is helpful for efficient global illumination because it lets the renderer send the rays in the places that count the most, instead of just groping around in the hopes of finding important light paths. Because sampling and evaluation are de-coupled from the shader execution, OSL allows a renderer to reorder computations in really interesting ways that could greatly improve speed and/or image quality.
Also, OSL is very consistent with physical units throughout, which not only improves the ability to accurately simulate materials and lights, but it also solves some longstanding problems in production, such as matching results between area light sources, emissive geometry visible to GI, and HDRI environment maps. These matches are now possible with OSL.
About OSL (Open Shading Language)
Open Shading Language (OSL) is a small but rich language for programmable shading in advanced renderers and other applications. OSL is similar to C, as well as other shading languages; however, it is specifically designed for advanced rendering algorithms with features such as radiance closures, BRDFs, and deferred ray tracing as first-class concepts.
The OSL project includes a complete language specification, a compiler from OSL to an intermediate assembly-like byte code, an interpreter that executes OSL shaders on collections of points in a SIMD manner, and extensive standard shader function library. These all exist as libraries with straightforward C++ APIs, and so may be easily integrated into existing renderers, compositing packages, image processing tools, or other applications. Additionally, the source code can be easily customized to allow for renderer-specific extensions or alterations, or custom back-ends to translate to GPUs or other special hardware.

Always have to call out where my Sony world and my Open Source world overlap.
Recently I got my invite to try out the new Dropbox service. I am a long time Folder Share user and had heard some good things about Dropbox. I have to say, I am very happy with the performance of Dropbox and was even more pleased when I found out there was a Open Source Linux client. Figured I wouldn’t be a good geek if I didn’t do a quick install and see how it performed. Here is a video of that effort.
Dropbox has clients that run on Windows, Mac, and Linux

Typically you have those applications you like and those applications you love to use but every now and then an application comes around that completely changes the way you work and those become the applications you can’t live without. For me, that application is Quicksilver from Blacktree on my OSX machine. Not sure exactly how to discribe what exactly Quicksilver is, to say its just an “application launcher” would be seriously underminding everything Quicksilver brings to the table.
It took me sometime to get my mind around what Quicksilver was and what it could do. I am probably a yellow belt when it comes to using Quicksilver, I am well beyond using the basic features but still haven’t really scratched the surface of what it can do to really master it. I use a similar application for Linux called Gnome Do and one for my Windows boxes called Launchy but neither of them have the integration and do for me what Quicksilver does. Even the Apple OS X built in Spotlight falls far short in my opinion.
Quicksilver can be a tough application to understand and I personally hadn’t come across a lot of good instructions on how to use it. Been doing the whole trial by fire approach. But fortunately one of my buddies over at Splunk has put together one of the best Quicksilver tutorials I’ve seen to date. Check out Michael Wilde’s Blog entry on “Mac Productivity with Quicksilver”
This is just funny
I think it goes without saying that I am a huge supporter of Open Source but believe it or not I am also a big fan of Bill Gates. You’ve got to respect what he did for the industry and what he does for the world through his charities. The guy is a geek’s version of Michael Jordon. I don’t agree with everything the man does obviously but I think the guy has a great mind and he will be missed in the computer industry when he finally moves on.
Anyways, I enjoy watching Bill Gates talk but I kind of caught something interesting in this last interview I was watching.
Here is a link to the interview:
http://news.bbc.co.uk/1/hi/business/7462156.stm
At about 1.45 Bill talks about how finding the source code for an operating system took him and Paul Allen to the next level on tinkering. I thought to myself how fortunate we were that he had that oppurtunity to look at and study an operating systems source code. It would have been a real shame if the ability to look at source code was deprived from Bill Gates. I wonder how many great thinkers Linux has or will inspire by offering them a similar opportunity.
Firefox 3 browser, 3 millions plus downloads worldwide. Wonder what its like being the only dude in Eritrea to have downloaded it. That guy (or gal lets be fair) deserves a some Firefox swag.
Interesting article over on ZDNet. I don’t know what surprised me more, “Microsoft apologizes to Open Source Initiative for policy violation” or to hear Microsoft actually has a “open-source and Linux team”.
