actually, Macintosh's expansion slots look like they are splitting with PC's again.
G5s are using PCI-X, but it looks like PCs are going to standardize on PCI-Express. PCI-X is faster and more expensive and incompatable with PCI-Express.
Both PCI-X and PCI-Express are both backwards compatable with new regular PCI cards, so you can't expect PCI to be abandoned soon. In a few years we may be back to the good old days of Nubus compatablity, maybe a lot sooner for video cards.
Yep, the Quake II engine is under the GPL, HOWEVER software doesn't have to be released under one licence. Quite a bit of software is released under the GPL and a propriety license, so people have a choice to either make their derivitive programs GPL, or pay for another licence, QT(the graphics API for KDE) is licensed this way.
Also, Quake II levels need not be under the GPL. If someone wanted to use the engine to make a new game, only the engine modifications would have to be GPLed, the artwork and level designs can be distributed however you like.
GPLed software that a company owns the copyright to is probably still recorded as an asset. I imagine SGI's XFS copyright is now worth more than it was before releasing it under the GPL. If someone wants to use XFS in their non-GPL OS they are going to have to licence it from SGI. Even if they put XFS under a BSD licence, there would still be some value as the creator as an "expert".
Some software re-released under the GPL(probably adding some asset to the original company).
Lab computer floppy drives are often broken and are some of the worst for destorying disks(springs from disks are left in the drive). If you are using floppies then going with a computer you have used succesfully before may save you a headache.
I've just been using my iPod to boot one of the G4s in our lab.
That idea has some merit, but arbitrarily extending the deadline isn't a good idea. Why not just allow people to vote anytime within a long period of time, say a month? People can mail in their ballots early, so why not do the same for online voting?
People would still wait until the end to vote and would get DDOSed then, but the voters wouldn't be disenfranchised totally.
Most base-stations that can bridge wired networks can't be used as a base-station at the same time, the DWL-2000AP can't. The ABS is pretty darn amazing and flexible.
The real value for me in Apple's Access Points is that you are getting a great Cisco WAP for a lot less, Cisco's radio's have some of the best sensitivity around. Add a nice antenna to a Apple WAP and you have one of the best WAPs you can buy.
the other legal accomplishment would be to uphold the GPL without frightening the world that OS is similar to the RIAA.
That would be IBM's Countersuit in this mess. SCO is the perfect target to go after for GPL violations. This could turn out to be VERRRY good for Linux people.
I don't know that much about Linux Sound, but/dev/dsp is the OSS interface, ALSA provides it as OSS emulation, but only one device can access it at a time. You need to configure your app to use the ALSA sound system,
You can configure this in most apps(Mplayer, KDE, XMMS, etc), once you set it to use ALSA, you can have multiple apps using your card at once.
I think a 7200 rpm drive is a mistake, if you want a fast drive you can pick up a 5400rpm travelstar drive with a higher capacity and a 8MB cache. The higher density will make the drive faster without killing your battery and keeps your lap cooler. 7200rpm is damn fast, but not worth the power it uses.
hmm, I've seen the same problems here, we have probably 25 old G3 imacs in service and maybe 12 eMacs. The eMacs were a mistake, don't buy any first revision of Apple's Hardware, we saw the same display issues, they haven't needed fixed in awhile now. The iMacs have all been exceptional machines, 2 ethernet cards have died, one was replaced under warranty, the other was auctioned off. However sadly it's not uncommon for ethernet cards to die here(PC or Mac), it's nice to have PCI slots. Most of our Macs are PowerMacs.
what laptop is this at that price? The warranty matters a lot on laptops. If I were buying a Dell laptop I would probably get the Inspiron 8600 (The whole 8000 line has been great).
The 8600 configured as you speced, except for a 9600Pro w/ SXGA+ screen, and integrated bluetooth is $2,654(they are running a free dvd-burner pro-mo so this will be a little higher after wed). Buying your second stick of 512mb at crucial brings the price down to $2,509
A Powerbook specced similarly, but with a G4 1.5Ghz, a 9700 w/ SXGA+ screen, and a 5400rpm drive is $2,999.00. Buying the second stick at crucial brings the price down to $2,829
The powerbook costs $320 more, pretty close. A sale in the other direction could make the powerbook cheaper.
I want a portable laptop, the 12" powerbook is considerably cheaper than a inspirion 300m, it also has more options.
complainging about an Apple's Hard-Drives is silly, they use same HD's every other OEM uses(whatever is cheapest).
Well, how do you maintain an integrated network card?
Make sure they are well protected from lightning, huge school networks aren't always the best engineered. I've seen cable run on the outside of the building because it was going to be temporary, and then left there for 4 years. Did you have multiple ethernet cards fry in your macs without a single failure in any of your PCs?
The eMac certainly had some horrible problems with it's display when it was released. The issues seem to have been worked out, but I still don't like it's design. It's probably not a good idea to buy a first revision of any computer, much less a lab of them.

The HOWTO has a LOT of info that you can ignore, but there are quite a few gotcha's if you aren't aware of them. It is the most complete reference I know of for getting X-windows setup with 2 seperate heads.
I guess I should have said that it is pretty easy, given a few things.
You are running a 2.6 kernel (I am)
You are running Debian (I am), Debian unstable has an Xserver reaady for multiple X-heads, and no special issues
It was easy for me at least, I didn't patch a thing or install any extra software. It was mainly an issue of getting the input devices all setup correctly.
My setup:
Geforce4MX/USB Keyboard/USB Mouse
Matrox G200-TV/PS2 keyboard/serial Wacom tablet
I don't use it this way anymore, I now have it setup as a regular dual-head box again.

It's a lot harder to get a dual consoled Linux desktop than a dual X-windows Linux Box.
If you want multiple consoles with seperate keyboards/mice, then you are looking for The Linux Console Project, I've never played with this
If you just want multiple X-Sessions running with sperate keyboards/mice, then you should just need to seperate all your keyboard, mice, and screens into sperate ServerLayout sections of your XF86Config-4 file. check here for documentation, This isn't actually all that hard.
depending on how it is slicing the CPU cycles, you could end up with each user getting exactly half of the CPU time, whether they are using it or not, in effect giving you two computers at half the speed.
Here is a link to Applica's website. They have made PC Buddy for a number of years. They have PCI cards to let up to 5 users use the same copy of Windows. The video cards included are strictly 2-D accelerated only though.
But if you could run Linux on cheap PC's and then use a 100 head windows box running VNC on each head, you would only be paying for the one copy of Windows.
Most offices can replace their software with open-source equivilants, this would let anyone who wanted to run an old Windows app to launch VNC and use MS Word if they didn't like AbiWord, Kword, or Open-Office.
Linux can have an a million people logged in at a time via remote X sessions.
VNC runs on the local machine on a local X-session, you can start as many of these up as you want, but you would want one for each user logging in via VNC, if you connect via remote X11 you don't need any special setup for a crap-load of users to log in.
From it's power requirements, WUSB is not competing with bluetooth, it's a rival of 802.11.
Heres a quick look at wireless specs(pretty rough)
Bluetooth - 50 meter range, 723.2 kb/s, 20mW+
802.11 - 100 meter range, 54Mbits, 200mw+
WUSB - 10 meter range, 480Mbits, less than 300mW
Most all WUSB devices are going to have to be connected to AC power. Why would anyone want to deal with the problems that come along with wireless devices, when they are going to have to plug the device in near their computer anyway? Not to mention that this probably won't come cheap.
Bluetooth on the other hand is here now, it's cheap, it's EXTREMELY low power, and it's fast enough for 90% of devices that make sense to be wireless.

- Cisco radio
- bridge/AP at same time
- built in print server
- AOL compatable modem($250)
- can use nice antennas without mod($250/$300)
- built-in POE($300 one)
It is one of the best WAPs you can get for the price. You can pick up a refurb of the $250 one for $200 at the Apple store.The real value for me in Apple's Access Points is that you are getting a great Cisco WAP for a lot less, Cisco's radio's have some of the best sensitivity around.

I could actually put it in my attic, WUSB's range is a piddly less than 10 meters.
why not an 802.11g base? I'd rather be able to position the base more than 3 meters from my computer and 54Mbits is plenty of speed.
