Re: [Wlug] Wlug Digest, Vol 144, Issue 2

by Jonathan Lettvin

I've been exploring HTML5 3D scene rendering. It appears to make good use of gpgpu acceleration. My first use of it is up on github: https://github.com/jlettvin/cubeHTML5 (repository) https://cdn.rawgit.com/jlettvin/cubeHTML5/master/cube.html (result) Additional layered technologies make excellent use. WebGL and Three.js are amongst the more mature. http://threejs.org/ http://stemkoski.github.io/Three.js/ http://threejs.org/examples/ http://threejs.org/examples/#webgl_custom_attributes_points3 The speed of development and resulting performance is orders of magnitude better than historical methods. I am no expert, but it is a remarkable technology. I intend to use it to develop and make dynamic presentations. It is not specific to Linux, but it is supported there. Is it worth using a wlug session on this subject? Just a self-serving thought.

Re: [Wlug] Topic for next Meeting?

by Tim Keller

We actually haven't done a round table in a while. David, I like your idea for the home automation / vision processing as well. I just went looking and there are 10+ companies that make linux based home automation products. I've messed with the the opencv stuff and my co worker is using it read his water meter and do OCR. Keith, it would be cool to have someone (other than me) talk about managing large amounts of data. Drop a line to your friend and see if they'd be willing to do a talk. I talked a bit about hadoop as well since I've been working with that. I could with some prep give a talk about hadoop if people were interested. I've also been playing with the parallel python stuff as well. My plan is to send out a reminder that the meeting is going to be next Thursday. It's a bit too soon to get anything put together on either of these topics, but we should talk them through next Thursday and see if anybody has more ideas as well. Thanks, Tim.

I would like to see a presentation on using linux for home automation or a presentation on using linux for vision processing.

If we can't get a speaker and a topic, let's do a discussion circle---everyone takes a turn to answer the question "For what do you use Linux?" I know some people use it at work to manage multi-terabyte databases, and some build little microprocessor gadgets, but I would be interested to know the full range, and maybe learn about some new applications. -- Keith

Hey Gang, What would people like to do for WLUG this month? Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".
