Ask Slashdot: Server Room Toolbox?
My two most important tools are a label writer and a knife. The latter to open boxes, tape and cable holders with. The former should be fairly obvious.
I use these more than screwdrivers,
Is there something wrong with the Adapteva Supercomputers?
Well, parallel programming is still a bit obscure, which as you know is the point of the whole project. Also, many interesting details were added late in the funding process. Check out http://canhekick.it/projects/adapteva/parallella-a-supercomputer-for-everyone to get an idea.
Also, do note that the $199 64-core option is dependent on the project reaching its $3M stretch goal, which I doubt it will. To be sure to get a 64-core, you have to pledge $750.
A Teacher Asking Students To Destroy Notes?
Legally, they could very well be seen as a transcript of a performance, which might be a form of IP infringement. In real life, however, it is ridiculous. To go to class means for a teacher to share information with students. That fact is taken for granted by all who would teach or learn anything. But maybe it's been taken for granted to the point where there is no law regulating it. Quite an interesting problem.
Enforcing the GPL On Software Companies?
I don't recall there being a part of the GPL that says you have to put your source on a web server. If they send it to you upon contacting them that would suffice, right?
