Do you know those little USB drivers which look like a pen? Well, they are better than floppies, and you can use them in your "legacy free, super secure" Compaqs, I think.....
I think Fast Ethernet and some switches would be enough, unless they are planning to use app servers or something like that. Probably they won't have a gigabit link connecting with Internet for each student...
I would like to know how expensive it will be when they start to have problems with those fibers =)
Try to install apt-rpm in your computer, if you are still using Red Hat. It will find all dependencies and install them automagically.
http://apt-rpm.tuxfamily.org/
This is a port from apt-get (Debian) to use RPMs, first implemented in Conectiva Linux (Brazilian distro). For Conectiva, there is also Synaptic, a front-end for apt-rpm.
The Man Who Counter is a very good book to read and full of Mathematics. It is a good start if you're trying to think Mathematics, not just applying formulae.
OK, Open Source has a lot of bugs, but who does list closed source bugs? I'm sure most of their bugs don't go public, because it is not a good market technique... It isn't fair to compare both lists.
The problem in the Dirty Bomb hype is the panic it may cause. I don't think a nail bomb won't affect those who aren't very near it, neither it'll contaminate water, ground or whatever.
Even if the Dirty Bomb also doesn't contaminate the envyronment, people won't be sure about that (because they cannot see it), and then... chaos.
You're right: you cannot compare apt-get to rpm files. But apt-get solves most of the dependency problems: you don't need to search that bloody xyz library thant needs zya version 0.9, etc
Conectiva Linux (Red Hat based Brazilian distro) has apt-get included, and also Synaptic (a cute front-end for apt-get). CL is not a major player in the Linux market, but its going to work within United Linux, maybe they'll include apt-get.
I like this distro because of apt-get, easy install, good and effortless portuguese support.
Yes, I did that. I upgraded a few packages each time, then I did an apt-get clean, and so on.
apt-get is nice

Is RPM Doomed?

I don't have problems with RPMs at all. I use apt-get since it was first introduced in Conectiva Linux, and I'm now using it in a Red Hat box. I upgraded it from 7.2 to 7.3, and the only problem I had was lack of space in/var to download the files (not my fault, but from the former sysadmin).
Today they are calling everything that may damage your computer a virus. In old times we used to call virus a program able to infect by itself, without the need of an user to execute it. Trojan-horses, by the other side, need to be executed by an user to infect anything.
I think most virii today should be classified as trojan-horses.
I doubt Windows is not modular (at least a little bit). They are using the microkernel concept since WinNT (a very small kernel and "servers" for the more advanced features) and dynamic libraries for most of the code (I think).
Maybe they can arguee they cannot strip some stuff because of dependencies. I am not a Windows expert, but it seems they won't go too far away with those claims.
But it is always nice to hear from M$ they don't know how to build a operating system =)
MHz is not everything. The number of instructions executed by cycle (IPC) and the number of pipeline stages are very important. For example, if a processor can delivery 10 IPC with a 200 MHz clock and another processor delivery 1 IPC with a 1 GHz, which one is the fastest? (a) The first one (right answer) (b) The second one (c) The CowboyNeal one
Of course it is not so simple, but just to think about: how do you compare an Athlon 1.6 GHz to a Pentium 4 at 2 GHz?
Slow is relative. Just because it doesn't clock at 2 GHz, it doesn't mean it is slow. As you've stated, they have vector operations, just like some supercomputers.
Maybe they are not usefull for every application, but I think they are powerfull for regular calculations.
I think we should have at least the choice of buying computer hardware WITHOUT any OS. M$ will complain about piracy, but now everybody know (I hope) there are other choices which don't imply in copying commercial SW (like FreeBSD and GNU/Linux).
NUMA means Non-Uniform Memory Access. It is a kind of computer where you have shared memory but you dont have the same access time for every processor to every memory position. Therefore, every processor will have access to all memory but sometimes it will take longer or shorter (if the memory belongs to another processor).
In a Beowulf cluster, you dont have shared memory (unless inside a node, if you have a SMP machine) and you must use message passing to communicate (unless you are using DSM--Distributed Shared Memory--, maybe with SCI).
People just don't know posting emails is almost like posting a letter in a transparent envelop... everybody from your neighboor to the postman may read it, if they want to.

If you aren't planning to go to the USA...
But I'm not sure our politicians don't believe that sw or algorithmic ideas cannot be patented. Most of them probably don't know what is an algorithm.
They'll write laws according with their intere$t$ =)
Are they going to give PCMCIA adapters to those who have notebooks? I found a 100 Mbits Fiber PCMCIA card for only $ 405 =)

Yes, this is great stuff!
You just have to find out where are the repositories you need, like freshrpms.net, and them add them to your sources.list
I'm used to update my distro to the last packages (OpenSSH, for exampled) using this tool.

Try Red Flag Linux. It's a Chinese distro, so your friend will be able to read, write, etc in Chinese.
The Man Who Counter is a very good book to read and full of Mathematics. It is a good start if you're trying to think Mathematics, not just applying formulae.
I'm sure you'll enjoy it.
Why was this rated "Science"?

Just my two cents.

I mean the coffee stuff! Coffee is always a "hot" trend (unless you like it cold =)

Sorry for the spelling
As a first step, they might make their system calls and programs have the same interface (parameters) than Linux.
I never cared about that bloody noise. But now you've started talking about it, it is really pissing me off!
My Genius mouse and my 5-years old keyboard are too noise (now I know they are)!

Today we have Linux distros running from a single CD, without HD install at all. And the processors used in these PS are very fast.
I think it is possible to build nice Beowulf clusters with PS2/3 running Linux, using a server with disk as a file server.
Has anybody tryed it before?
