You've obviously never looked at or tried to implement an ITU protocol. Not only does getting an actual copy of any of their protocols cost a fair bit of money, they're all excessively complicated and rely on a large stack of other complex & expensive ITU protocols.
And the annoying part is that this is, in fact, the case with many of this software. Due to the braindead security decisions MSFT made about IE, any user can install things, through IE, that will have an effect on the rest of the system for all users.
Odds are that CET stands for "Computer Engineering Technology".
I've never really figured out if there is some difference between a *ET and a *E degree, tho. I'm not sure if it's just an alternate naming convention or an 'applied engineering' degree...
Going to XDMCP seems a bit on the extreme side; moving over to an NIS/NFS (or other more modern or secure systems like Kerberos/LDAP and AFS) and forcing all user files to be written to their home directory which is shared over NFS.
There's enough tools out there (such as cfengine) to handle updating the desktops that, if you have decent desktops, I can't see why you'd want to make them all dumb terminals.
I think part of the reason y'all are moving away from using SSNs is because of federal privacy regulations (HIPPA, right?). The idea is to separate your medical records from the massive ammounts of data that are tied to your SSN.
Actually, I was almost -forced- to do this a few years ago.
My father was in the military, stationed overseas, when I was born so there was some extra paperwork involved to make sure that I was recognized as a US citizen. My parents also had to get me a SSN in order to get me a passport (if you think passport pictures are ugly just wait until you see a baby's passport picture) so they could travel with me.
Fast-forward 17 years to me applying for student aid for college. I get a nice letter (I forget if it was the university or the gov't) claiming that I'm not eligible for federal aid because I'm not a citizen. It turns out that somebody had input an incorrect value into their database.
The people at the social security administration were rather convinved that the only way to fix this was to get a new SSN and I was about to do so until my father contacted our congressman and pulled the 'I spent 20 years serving my country and I have to deal with this bullshit?' routine.
Strangely, it only took about a week to get fixed after that.
It's far easier to pirate games on the PC than it is for consoles. Modern consoles generally require some sort of physical modification in order to play burned discs while a simple binary patch will make a pirated PC game playable.
The idea is probably that, since it's easier to get a pirated PC game working, lowering the price will entice more PC gamers to actually purchase the games.
It makes sense, really... If you're building an app that's intended to be used by clusters, why would you write it for XP? Having to spend an extra $100 per node really starts adding up when you've got serveral hundred or thousands of machines...
By your logic, win2k sucks because it's nearly impossible to find drivers for OEM Aureal cards now that they're out of business.
I'm getting tired of these complaints about ease of installation and hardware support; most machines out there are either installed at the factory or have the OS installed by relatively competant people. If an OS isn't broken, the average user should NEVER need to reinstall.
By the logic people use in these arguments, your grandmother should be able to replace the engine in herFord with one from a Honda without ever having recieved special training, reading a manual or ever having opened the hood of a car & expect it to work the first time without any complications.
I call bullshit. At work, I routinely have to install win2k on older machines, some of these drivers are damned near impossible to track down, even when you know the manufacturer of the device....and don't even get me started on older Sony Vaios; they've got all sorts of custom hardware and Sony doesn't bother writing drivers for any OS other than the one they shipped with.
I remember, when these first came out, somebody was talking about the crazy-mad wicked resolution these things were printed at. Have they figured out how to get my HP Deskjet 500 to print these things?
Look around the engineering departments at a US yniversity and you'll see that like half the students are Indians and Chinese. We can't really get down on big business for sending work over there when our government run universities are training them in the first place.
It's not really so much different than going to war against terrorists/dictators that the US funded and got into power a decade ago...
to date there has been no deaths or long term effects
How long has this been going on for? A year? Five years? Ten?
That's the thing about long term side effects, they happen many years down the road. If 15 years after trying some drug people start spontaniously combusting or comming down with Parkinson's, how's that change your view of long term effects?
What counts as something you can 'actually afford'? If you don't plan on spending at least $100 on a graphics card, you're going to get shit (think Intel + Celeron). For right at $100 today, you can get a Radeon 9600 or a geForce FX 5700, current generation (DX9) cards that have very respectable performance. (for slighly less, GF4 Ti's and Radeon 8500/9100s are still available, giving you the last generation's high-end for cheap).
The current generation's low-end cards (as well as the last gen or two) aren't really worth the money if you want to do anything more complex than 3d screensavers. The FX5200 is a dog that isn't really any faster than the GF4mx was & isn't really worth using in DX9. The Radeon 9200 is actually slower than the 9100 & 9000. Eventually, the FX 6x00 core will be adapted to a chip that sucks just as much & you'd probably be better off getting a high to mid range card from the previous generation.
Intel makes a 3.4GHz P4EE and AMD has the Athlon64 FX-53, both of which are $800+ CPUs, you don't see (many) people complaining about the top of the line chips there being over twice the price of the chip 2 steps down ($275 should get you an Athlon64 3200+ or a P4 3.2GHz), yet when a new graphics card comes out and it's $500 every lines up to talk shit.
Yet there's always going to be something in the $100-150 range (what's considered reasonable mid-range for serious gaming) that's worth buying (barring some sort of hyper-inflation); you don't always have to have the latest & greatest thing on the market. Game manufacturers realize this and target their games to be playable on $50 cards, ideal for $100-150 cards and able to take advantage of the $500 cards.
Where did you ever get the idea that it was a bad idea? The nVidia boards have been kick ass & rock solid from almost day one. Currently, the only real issue that anyone would have with them is that the onboard audio & network on some nForce2 boards (but not all; mine has a RTL8139 and uses AC'97 drivers) aren't the most well supported under Linux, but the OSS drivers are coming along nicely.
A cluster is almost always _not_ a heterogenous environment. On top of that, the individual cluster machines should not have, nor do they need, access to the network as a whole. Compared to things like computer labs, HPC clusters should be the easiest thing to secure, since you -can- firewall the hell out of them.
There's no excuse, when putting up a several hundred node cluster to not get an extra machine through which it needs to be accessed that is not part of the cluster. That machine can trivially be kept secure & the cluster can then be updated as is convenient (IE - not replacing the kernel in the middle of a 3-week long computation; even at that, tho, anything that's going to take 3wk should be able to checkpoint itself without loosing much).
The entire (up to date) Windows lab here gets compromised & backdoored to hell and everyone just says "Have it working by tommorrow". A Linux cluster gets compromised and they issue a press-conference.
There's a difference between going to a website and having that website pop up an advert and having some program sniffing your IP stack and tossing up pop-ups for Chevrolet every time you visit ford.com.
I'm sure all that stuff is real nice, but the thing that most people are interested in SFU for now is that it provides beautiful NFS & NIS integration with your windows domain.
Girls have always had a lower barrier for entry into any of the 'elitist' social circles. Take the example of 'captain punk-rock-opolis':
You've seen them, the -really- punked out guys, tats and chains & spikes and band patches and tatoos of band patches on their spikes and whatnot? Look at most of the girls that hang out with them (other than the occassional super-punk-chix0r). She might have a single spiked bracelett and a wallet chain. Next week, by simply removing that bracelet, wallet chain and boyfriend, she fits in elsewhere.
It's the same in geeklandia; since the whole 'scene' is primarily of interest to males, girls that are even remotely interested in the shit (and the guys in the scene) are just accepted while the guys need to prove themselves to fit in.
The problem is that even locked down but still usable accounts can still install things through IE. Users that can't install or uninstall software normally get priveleges elevated while in IE.
