Campaign for beowulf-less people @ SlashdotSlashdot people: I have good news for you. I know you always want to build a beowulf cluster - and I've found top-secret information on how to make your own! Beowulf cluster Mini-howto Note: the server actually isn't a beowulf cluster, so access it *now* before the server *goes*.

Re:Best improvementsNow you wouldn't think of developing on UNIX with anything but GCC and the associated build tools.
Unless, of course, you require top numerical performance from your CPU.
Compile software like an open source ab initio package, CAMPOS, with GCC and you get decent run-time performance. Compile it on P4 with Intel's compiler and math libraries and you get 2 - 2.5 times better performance.

Re:VHDL, Verilog and "those other languages"
I'm surprised you didn't mention Verilog -- it's an HDL that is (outside of military contracting) much more popular than VHDL.
[SNIP]
The reason for mentioning VHDL as opposed to Verlog is probably that he's a european HW designer. European designers use VHDL and everyone else uses Verilog.
BTW: I'm studying electrical engineering at Technical University of Denmark and I've never written a single line of Verilog - none of the professors teach it since it would be hard to get a job in europe. -
Re:One DOS to rule them all!
heh, reminds me of this:
Recently one of my friends, a computer wizard, payed me a visit.
As we were talking I mentioned having recently installed Windows 98 on my PC and that I am very happy with this
operating system. I also showed him the Windows 98 CD, to my surprise he threw it
into my micro-wave oven and turned on the oven. Instantly I got very upset,
because the CD had become precious to me, but he said: 'Do not worry, it is unharmed.'
After a few minutes he took the CD out, gave it to me and said: 'Take a close
look at it.' To my surprise the CD was quite cold to hold and it seemed to be heavier
than before. At first I could not see anything, but then on the inner edge of the
central hole I saw an inscription; an inscription finer than anything I have ever seen
before. The inscription shone piercingly bright, and yet remote, as if out of
a great depth:
4F6E65204F5320746F2072756C65207468656D20616C6C2C 20 4F6E65204F5320746 F2066696E64207468656D2CDA4F6E65204F5320746F2062726 96E67207468656D20 616C6C20616E6420696E20746865206461726B6E6573732062 696E64207468656D
'I cannot understand the fiery letters,' I said.
'No,' he said 'but I can. The letters
are Hex, of an ancient mode, but the language is that of Microsoft, which I shall not
utter here. But in common English this is what it says:
One OS to rule them all, One OS to find them,
One OS to bring them all and in the darkness bind them -
mirror
I put up a mirror here (fast connection, hit it as hard as you can...)
And now I got killed off by the lameness filter, what's up with that, anyways?

Re:Genome Sizes.
Haploid Genome Sizes (collected from various sources):
A more comprehensive list of genome sizes is here:
http://www.cbs.dtu.dk/databases/DOGS/abbr_table.by size.txt.
These pages show how much of each organism is finished and publically available:
http://www.ebi.ac.uk/~sterk/genome-MOT/MOTgraph.ht ml
http://www3.ebi.ac.uk/Services/DBStats/
Arabidopsis thaliana: 1.17 x 10^8 bp, ~25,000 genes.
25000 genes is near the low end of the range for the estimates of the number of genes in the human genome:

Re:So how log can Mores Law continue?Even if we can make chips smaller and smaller. There must be a limit. I mean what is the smallest number of atoms you need to build a transsistor?
Well, these guys claim they can switch a single hydrogen atom between two silicon atoms.

So, noone thought of TCL?
It's not just for GUI, you know
:)For a web-server you can have either:
- mod_dtcl in your Apache
- install NeoWebScript, which is an Apache with TCL and tons of TCL extensions
- use AOLServer -- don't let the name scare you, it is a highly-optimized multi-threaded web server. Its main features include database connection-pooling and a powerful Tcl API for application development
- install tclhttpd -- a web-server written entirely in TCL (with SSL support available), which works quite well for me
Your database may be MySQL or PostgreSQL (my preference).
PostgreSQL can be built with TCL support (a client library loadable into a TCL interpreter) and a server-side extension allowing you to write server-side procedures in TCL (not anemic at all, IMHO). Postgres can be built to support SSL connections and comes with pgaccess -- a fairly powerfull database browsing and management GUI-tool (written in TCL/TK).
For MySQL there are also at least two TCL-extensions that provide for TCL access to its client API:
For distributed objects, etc. you could use TCL-DP. Don't let the word beta scare you -- it does wonders. The remote ends can even talk over e-mail!
And there is nothing to beat TCL/TK for a cross-platform front-end application! That's a given...

P.S. It sucks that paragraph-tags can not have attributes in

the real question...
All right, I don't know very much about authentication under linux, but:
At my university we have a shitload of Sunray2's terminals. The have a smartcard reader, which is, as the person asks, used for authentication. This is the way it works: instead of logging in and out, you just throw in your smartcard. This is not the cool part, the cool part is, that, when you insert your card, your desktop comes up exactly like you left it. Programs and files open, window positions, the works.
So, getting the authentication part should be possible, but getting the "desktop popping up the ay you left it" is the tricky part, at least if you ask me.
or else I'm just drunk and babbling about stuff I don't get...?

Re:Robotic Cockfighting!There are a couple of contents for "real" robots - in fact there will be one at the Technical University of Denmark next week:

(I don't think their picture gallery works, but try looking at the danish version and search for "billede")Does anyone have links to similar contests?

medical anthropology and genomic linkshi all, as a medical anthropology student i have been compiling info related to the the genome project (HGP as well as the HGDP) for quite a while. at the following site
http://www2.ucsc.edu/~bobb aq/anthro/med/medanthlinks.htm, you'll find info regarding genetics/genomics bioprospecting/biopiracy, bioethics and the many other issues of concern to medical anthropologists. of particular interest to researchers is the list of course syllabi in which you'll find many bibliographic sources and book lists. the following is a clipping of the "source code."Genomic (and anti-genomics) Links [To Top]

More InfoI thought these terminals was old news, since 100 of them has just been installed in one of the "databar's" here on the Technical University of Denmark.
They are _extremely_ dumb, not even X terminals. Instead you have a terminalserver, that runs one X server for each SunRay terminal. Then the bitmapped graphics is transfered over the network, in some compressed format, all the terminal does is send the keyboard and mouse events the other way, and put the graphics in the framebuffer. Exactly like VNC and Citrix, not something that sounds very intelligent.
I have only used them briefly, but they actually seem very fast. Ofcourse I don't know how they stack up under heavy load. Don't expect fullscreen MPEG on them though
Tech details: 1280x1024 @ 76 Hz
24-bit colors
10/100 Mbit Ethernet connection
Composite video input
Stereo audio out/Mono microphone in
4 USB port
ISSO approved smart card reader
The setup is 100 terminals, with 50 each on a Sun250 Terminalserver (Dual USparcII, 2G ram)
These only do the graphics, 50 X servers on each there is a HPC6500 for the CPU power with a couple of E10K to come.
I don't know if the page describing the new setup is available from the outside but try:

Using higher level languages w/ NNs
You can also check out Octave which may have somethings. This is a language similar to MATLAB. There is a toolbox that will work under MATLAB (and maybe Octave) from the Technical University of Denmark located here. By the structure of MATLAB and Octave, the source code is usually "open" (read: you can look at it) and it is in this case as well.

RPM here
I have made the i386 RPM available here (for a short time).
