I have no opinion on EU computer science programs, however I know for a fact that many EU countries don't have the equivalent of the US Master's degree. For example, the French 'license' is often thought of as being the equivalent, but most US universities will not recognize it if you apply for a PhD.
As far as I know, most EU PhD are recognized in the US.
We're using the APC Environment monitoring device here. Low cost, works well, has an embedded web server for ad-hoc polling and is SNMP-pollable for MRTG integration (or any other). It also has dry contacts for things like door sensors or HVAC alerts.
The standards exist, but no one has written the server.
Then take a look at Sun's Sun ONE Calendar Server. It's a new revision of a relatively old product (based on Netscape Calendar Server, but rewritten from scratch), aimed at complete IETF standard complience. It's based on CAP and iCalendar.
In addition, it has a web interface for universal access.
Oh, and I also want write support for LDAP address books in Mozilla.
Well, it's there I think. I use Mozilla 1.3, and in the address book there's the option to add an LDAP server. Granted, I haven't tested it yet, so it may not work.
It's a commercial product, yes. But it seems to fit the requirements: It has a web-based interface for universal access, plus iCal or XML export, and it has a data exchange module with Palm desktop and Outlook.
RAID-5 will make your system more reliable, but not bulletproof. Two weeks ago I had a 1TB RAID-5 fail on me because a SCSI cable went haywire. Guess what, even on RAID-5 you have a few disks per bus, so you're still at the mercy of a single point of failure. Unless you have dual-attached FCAL, of course.:-)
You just said it: your switch doesn't support raw frames. This is critical to get decent performance out of GigE. The explanation is simple: GigE still uses CSMA/CD, even though I don't know of any GigE hub. Every time a NIC needs to send out a frame, it needs to listen to see if anyone is already transmitting. This is defined as a number of ms and is the same length of time from 10Mbps to GigE, to allow compatiblity. So the longer your frames are, the smaller the relative time wasted waiting. Also the ethernet frame header is the same no matter what the frame size is, so the overhead cost gets less important with larger frames.
Remember too that it's not bandwidth that's the problem in clusters - it's latency. That's why Myrinet is so damn costly. Even current cluster interconnects don't need more than 10Mb/s bandwidth - but they need as little latency as is possible.
I agree that latency is very important for some problems. But for others, bandwidth is as important. One application my lab uses needs to transfer interfacee information between nodes for each timestep. So every 60 second of computation we need to transfer roughly 100MB of data. So GigE makes this transfer take about 2s instead of the ~15s of FastE.This is significant.
Thank you for your interest in Movielink. We want you to take part in the powerful Internet movie rental experience that Movielink delivers; however, you currently do not meet our minimum system requirements. You will need to adjust the following:
You Need Windows 98, ME, 2000, XP
Of course, if I install Windows they'll still complain that I use Mozilla...
The way I read the first section, an OEM is 'protected' if they sell dual-boot computers, but not if it's a Linux-only, or no-OS machine:
...shipping a Personal Computer that (a) includes both a Windows Operating
System Product and a non-Microsoft Operating System, or (b) will boot with
more than one Operating System;
No application or optimization goal is stated. From experience, data warehousing can live with slower drives than OLTP, but requires massive storage.
Many companies are selling IDE-based RAID boxes. For instance, take Nexsan's ATABoyII (Sponsored link). It has 1TB of usuable storage (hardware RAID-5 with hot-standby disk and battery-backed cache, redundant power supply and fans). The FCAL version is I believe close to $18,000 each. So 50 TB would be $920,000. Then you need FCAL switches, fiber optic lines, and a few servers to serve the data. Overall, including power conditioning, air conditioning etc, I think $20M is overkill. They're probably going with EMC or Hitachi, which have very nice to configure (GUI), mostly reliable but completely overpriced arrays, and in this case $20M looks right (including consulting fees).
Frankly, all term papers, research article, etc are done using LaTeX. Instructors do NOT want a Word document, as its layout on screen depends on the printer you have selected.
First choice is always PDF/Postscript. Second choice is source LaTeX.
Why LaTeX ? All research papers worldwide are done using LaTeX. Publishers provide their own LaTeX stylesheet, so providing a LaTeX source saves them time. LaTeX looks really profesional, and you don't need to waste time doing layout.
Window seats are the worse with current planes: you have no leg room, reduced head room due to the curvature of the bode of the plane, and usually you're close the to engine (noise!).
Roller coaster ride ? Probably not. At least, not worse than with current planes.
Emergency evacuation ? In ideal condition (rested passengers, perfect lighting, no panic, etc) when tested by FAA, evacuation is done on time only 75% of the time. Evacuation of an airplane is a big joke with current technology.
As far as I know, laptops that can connect an external monitor have graphic chipsets that support two outputs, but the outputs come from the same framebuffer, therefore both show the same picture.
One thing would be to get a PCMCIA graphic card (expensive, in the $400 range last I've seen) or have a laptop with a PCI slot (I've never seen those).
XFree86 does support XINERAMA which takes two framebuffers and makes a single desktop out of them.

Yes, Oracle is the way to go. Not only because that's where the market is (though it does help), but also because most free databases don't implement full relational databases (they don't have all the ACID properties. While it's possible to work around those limitations, that's no way to learn a new skillset.
I can only second that. After trying to design databases before learning the theory in depth (thinking that an introductory undergrad-level class was enough), I had to face the truth: Database design is a complicated task.
The great thing about ICC is the automated vectorization using MMX, SIMD and SSE, as well as automated code dispatch to automatically use whatever feature your CPU has - one binary, many CPUs.
I beg to differ, but the IBM T20, as many other laptops, use a miniPCI card for the internal modem and network. That mean that the Lucent is only one of the possible options. In my case, my T20 has the 3Com combo card. The ethernet works, but no luck with the modem.
Microsoft have Visual Basic for Applications translated I believe... At least in Excel, if you have the french version all the reserved words are in french. If you open the same document in the english version of Excel, everything is magically translated in english. Unfortunately you cannot code in french with the english versions, which makes it hell to move from one environment to the other!

MPEG4 is open. The licensing fee is for the patents which cover the MPEG4 technology.
We are evaluating a dual Itanium2 machine right now. It's screaming fast, but with the price point I doubt we'll buy any.

According to pricewatch.com [pricewatch.com] the current going price is $30 - $49
Compared to $3 for an ethernet cable, the point is still valid.

True, an O3K can scale farther than the Starcat, but it isn't as redundant, doesn't have domains, and cost a LOT more than the StarCat.
SGI's future prospects are also dim, it's not a safe long-term purchase.
