The field you want, in general, is called accessibility. I tell you that so it can help your Google and other searches. I encourage you to reach out to the organizations listed on this Wikipedia page. I know some of them personally as I'm blind and a PhD student in computer science and an accessibility researcher, so I'll be more than happy to perform introductions on LinkedIn, email, twitter, whatever you like, just let me know. Here's the Wikipedia page listing some organizations. I'd start with Able Gamers. Mark's a good guy. http://en.wikipedia.org/wiki/Game_accessibility Next, I'd encourage you to get on twitter, if that's possible. I can connect you to tons of folks to cover everything from one handed typing approaches (both paid and open source solutions), speech input alternatives, strategies developed by other users of technology with the use of only one hand, and so forth. I'm @SinaBahram on there. Just drop me a line. Btw, the accessibility community often goes by the numerical acronym A11Y, so look for #A11Y or just a11y when Googling around, and that can help some of your searches as well. Sorry if this post is a bit disjoint. I would love to leave more comments on Slashdot and interact with it more, but Slashdot has repeatedly ignored my various emails and other attempts to reach out to them, since I use a screen reader and there are some serious accessibility issues that could so easily be fixed if I could just get ahold of the right person *poke poke to anyone who reads this*. To you or anybody else looking for more information on accessibility, technology used by folks with disabilities, etc., just contact me via whatever mechanism you like. It's all on my site, which I'm not sure my profile links to, so here it is. www.SinaBahram.com I hope this helps, and please don't' hesitate to contact me so we can get you connected to the right folks to get you gaming again.

Unfortunately such a cluster doesn't exactly optimize sheer performance because there's lots of communications back and forth, no shared data model, etc. Granted, due to the low memory constraints, the data could be replicated on each Beowulf compute node; however, then different costs are assessed for intrathread communications. Furthermore, I'm guessing you just mean put a few processors in each box and get 10 or so of them, but at that point is a Tesla solution not better?

I've looked at the latest Tesla card, as well as the 4 Teslas in a box solutions, and am having trouble justifying the markup for what's essentially "double precision FP being enabled, some heat improvements, and ECC which actually decreases available memory (I recognize ECC's advantages though)." Spending close to $11K for the 4 Teslas in a 1u setup seems to be the only solution at this time? I was thinking that GTX cards can be replaced for a fraction of the cost, so should I just stuff 4 or more of them in a box? Note, they don't have to pay the power/cooling bill. Amazon is too expensive for this level of performance, so can't go cloud via EC2. Any parallel architectures out there at this price point, even for 5K more? Any good manycore offerings that I've missed e.g. somebody who can stuff a ton of ARM or other CPUs/GPUs in a server (cluster in a box)? It would be great if this could be easily addressed via a PCI or other standard interface. Should I just stuff 4 GTX cards in a server and replace them as they die from heat? Any creative solutions out there? Thanks for any thoughts!"

This is a good point. Thank you. Again though, at these prices, it's almost worth rechecking calculations than paying for such an insane markup, no? I look at the various GTX cards, then at the Tesla, and I come away unimpressed at the differences per unit cost. So, no, I'm not sure that I don't need ECC. I'm willing to entertain the various possibilities though.

It's mainly single FP operations that I'm parallelizing, but double precision would be "nice to have". Thanks for any thoughts!

epiphani writes "After the recent kerfuffle around a replacement for syslog, Rainer Gerhards (the lead developer of rsyslogd, used in most Linux distributions) has responded to the paper in an attempt to clarify many of the misunderstandings. In his post, he points out the inherent misconceptions around the difference between syslog the protocol, syslog the API, and syslog the application, and makes the point that the systemd proposal ignores most of the last 10 years of enhancements to both protocol and application."

QuantumMist writes "Researchers from Southern Illinois University have published a paper(PDF) comparing Perl to Quorum (their own statistically informed programming language) and Randomo (a programming language whose syntax is partially randomly generated). From the paper "Perl users were unable to write programs more accurately than those using a language designed by chance". Reactions have been enthusiastic, and the authors have responded."
