espes··on Xbox 360 Emulator Research Project
The Xbox gpu and apu are 'off-the-shelf' in the sense that they were re-used in nvidia retail chips. But you're right, that doesn't mean much in terms of public documentation.

So you do some reverse-engineering. On the whole it isn't much work than other consoles of that generation. The only reason there hasn't been any activity is because nobody (outside of the Xbox backwards compatibility team) sat down and did the work (because there's no incentive to)

You have to use an Xbox console (or specially modified DVD drive) to dump your discs.

That post is actually more meaningless speculation than accurate.

So the thing is:

> tricky graph searches

> finding eigenvectors

> balancing trees

> non-recursive quicksorts

All these 'scary' 'hardcore' things are covered in the first year of most good CS programs.

espes··on Internet connectivity in Sub-Saharan Africa
On South Africa, it's more like 50-150 rand per GB (~4 - 13USD) [1]

Mobile data in South Africa is actually pretty cheap in absolute terms, though of course it's still extremely expensive compared to average income.

espes··on New South Wales Attacks Researchers Who Found Internet Voting Vulnerabilities
iVote in a nutshell:

"The NSWEC believes that unfettered access to source code by the general public would not be in the best interest of the State" (http://www.elections.nsw.gov.au/__data/assets/pdf_file/0003/...)

This apparently matters so much that it was specifically criminalised:

"A person must not disclose to any other person any source code or other computer software that relates to technology assisted voting under the approved procedures, except in accordance with the approved procedures or in accordance with any arrangement entered into by the person with the Electoral Commissioner. Maximum penalty: 5 penalty units, or imprisonment for a term not exceeding 6 months, or both." (http://www.austlii.edu.au/au/legis/nsw/consol_act/peaea19123...)

espes··on Nvidia's 3D Tegra driver now open sourced
It looks more like the very beginnings of a reverse-engineered driver effort.

The current shader "backend" (that is, a microcode assembler) is at https://github.com/grate-driver/grate/tree/master/src/libcgc. Shader compilation would be done by mesa. The rest of libGLESv2 seems unimplemented for now.

espes··on Nvidia's 3D Tegra driver now open sourced
Except this is totally unmaintainable as "open source" since there isn't any documentation or even any sort of register listing: https://github.com/grate-driver/grate/blob/master/src/libhos...

Actually, the way it's written it seems that folks at Avionics Designs did not have access to any documentation and it's pretty much a reverse-engineered effort anyway.
