Re:Surprise? Why?
In 2008, there were some 30 embedded microprocessors per person in developed countries (PDF). Most of those don't have plenty of memory. There is a whole entire world out there that you are likely unaware of.

Re:WTF?!
Brazil is not an example.
Looking at Brazil's GDP there is no growth. I'm not sure how you are measuring to claim Keynesian is a success.
Looking at unemployment rates, it depends on the portion you are looking at. While the rate of unemployment dropped, so did the wages of the lower class. Factoid.
Wealth disparity in Brazil is one of the worst in the world.
Brazil by it's own terms is called "Post Keynesian" because Keynesian principles pretty much failed. I'll give a link in a moment, but want to make sure you pay attention to what the document claims and not the titles. Such as...Aggregate demand constraint - As we have already stressed, a laissez-faire market economy does not create a level of aggregate demand consistent with full employment. and the whole of Inflation constraint. Here is the link.

widespread negligence, incompetence and Corruption
Brazilian home PCs are infested with all the kinds of stuff simply because the users do not care at all.. This alone is not enough, though, since pretty much everyone around the world behave like that.
The problem is that ISPs simply don't care.
I work at the Brazilian Gov't and even security reports from me are bluntly ignored by those ISPs.
You may try to report to CAIS (which is supposed to be "the" security network center in Brazil for the national academic network) and you know what? You'll receive and acknowledge response and that's it, nothing else will happen.
The only time they do something were in cases such as fake Paypal pages, I believe because there was money involved.
An example on how things work here:
Once we complained to CAIS about this scum from this university which were deliberately sending their spam (not an infected machine sending random viagra messages) and guess what CAIS did.. Exactly, nothing.
I suppose that junk is related to some project they've managed to get public money from, because we complained so many times and nothing were done (there's _always_ something fishy involved).
Until I picked up the phone called that university directly and told them I would block them completely unless they stopped that spam.
The guy who answered me simply started to say he would talk to the Rector, to politicians XYZ and who knows else, and implied that I could get into trouble.
To shorten the history.. In the end we've managed to stop that junk. But see how much did it cost.
I know so many rotten histories on Brazilian Internet, from the gov't side, from the private companies... A book could be written about that. -

Re:Got Torrents??
Where are you?
In North America, I'd recommend ftp://carroll.cac.psu.edu/pub/linux/distributions/ mandrivalinux/devel/iso/2008.0/ . In South America, ftp://ftp.c3sl.ufpr.br/MandrivaLinux/devel/iso/200 8.0/ . In Europe, ftp://distrib-coffee.ipsl.jussieu.fr/pub/linux/Man drivaLinux/devel/iso/2008.0/ , or ftp://ftp.nluug.nl/pub/os/Linux/distr/Mandrakelinu x/devel/iso/2008.0/ if that one's slow.
We don't do torrents for beta releases as the demand is not usually high enough to warrant it - the FTP mirrors usually cope with the demand easily. -
Unix-based does have this already
XAT, the "X Address Translation", does this kind of work already on Unix systems. Take a look here: http://www.c3sl.ufpr.br/multiseat/xat/

Mostly old news; multiXnest
multiXnest is designed to run several user X sessions on one computer. It's actually meant for multimonitor setups, but it can certainly do many users on one monitor too; just that it hasn't seemed like a good idea to anyone, and still doesn't to me.
The MS solution does seem to be intending to add some more integration than multiXnest can do, though, what with the moving mouse cursor over to the other session. I'm sure the innovation of being able to move one's cursor over the entire screen will be a patentworthy addition.
-
Re:You need to run two instances of X.
For naming USB mice, use /dev/input/mouse0, mouse1, mouse2, etc.
For keyboards, use the /dev/input/eventXX or the "physical" devices using the "evdev" keyboard driver.
See this document:
http://www.c3sl.ufpr.br/multiterminal/howtos/howto -evdev-en.htm
You can use up to 4 SiS video cards, or a combination of Matrox cards, or even 4 NVidia GeForce 2MXs if you use the NVidia-supplied driver.
Cool, eh? -
Re:The third world need wireless mesh.
Huh?
Now, I'm pretty sure that there are places that are just like you described... but I guess it's not a rule.
See, I live at Brasil... we're on the third world, but we're also a democracy, as every other country here at South America.
And we know how to grow crops very well, indeed our governament agency for agriculture, EMBRAPA, develloped some amazing stuff like plague resistant varieties of a number of vegetables, that are also more productive. And agriculture is an industry around here, we have a high production of cereals, and export it to the 4 corners of the world.
As for housing and public shcools, things could be better... but we got some amazing stuff going on Curitiba like the project Four Head [ http://www.c3sl.ufpr.br/multiterminal/index-en.php ]
So, I think that we could use some public wireless networking here. We can use also some more computers, like that AMD PIC, and Open Source software. -
Re:Linux is no good
It'll work with Linux, but you need a patched kernel. See here.

Re:Use Linux systems instead, like thisAh, yes, it's a typo. It should have said "2 to 16 users", of course. The number 16 comes from their last entry in the faq, without any further info (you also need USB slots, of course, but the USB bus can take 127 devices...). It's possible to add additional PCI slots to your system, though, unless you have one of those motherboards with lots of PCI slots already. Search for "PCI expansion system" or PCI backplanes.
Here's an article about using PCI expansion systems (written by a manufacturer of such): Massively Parallel Data Acquisition. By expanding the PCI bus into unique topologies, data recorders can scale in both density and data rate.
Whether that works for shuffling data the other way to PCI graphics cards as well, is left as an exercise for the reader.

Use Linux systems instead, like thisLinux Multi-Head: Share a single CPU and RAM among 2 two 16 users, each having their own screens, keyboards, mice etc.
This was also discussed on Slashdot a short while ago: FourHead: One PC, Four Users

I was able to download and use an ogg encoder on my home pc, but can't find on one their site today. Can someone provide a valid url?

Cher Patent Extension Act?
This is an open standard. It's just patented. Patents expire.
Not if Fraunhofer and the pharmaceutical companies manage to stuff a few thousand dollars down a few senators' pants and get some sort of "Cherilyn Lapierre Patent Term Extension Act" passed. Hell, if it worked for Sonny...
I'll publish them at least in MP3 format, and maybe Ogg if I can get a good encoder.
I have a feeling that if I publish Ogg, it's not going to get downloaded very much
As !Xabbu mentioned, Winamp 2.80 and later support Ogg out of the box.
