I think you don't even have to write any software to do this, you could just set the gateway as the default router with a very narrow netmask (255.255.255.255) Grtz, Jeroen
That's not going to put the wireless nodes into infrastructure mode.
Sooo... why couldn't a linux box do the same thing?
It could... but note that the gateway probably does more than just link the wireless network to your ethernet. 802.11 networks can run in two modes: ad hoc and infrastructure. In ad hoc mode, each wireless node talks directly to the other wireless nodes. In infrastructure mode, all stations talk to the gateway, which relays the message to the other wireless nodes (or to the ethernet). The advantage of infrastructure mode is that the gateway acts as a repeater, increasing the range; instead of all nodes having to be within x meters of each other, they have to be within x meters of the gateway. You can have a couple of these gateways, increasing the range even more.
That said, for most people, setting up an existing box to be a bridge or router between the wireless and wired networks is gonna be cheaper than buying the gateway:) And that's not to say that you couldn't use a Linux box as an infrastructure mode gateway... probably just a matter of writing the software. (I'm not a Linux guy, so I have no idea whether the software already exists or not).
I just called around to all the IMAX theatres in the Houston area (there's 3). The movie is not scheduled to be shown at any of them.
Have you tried the Edwards Marq*e Stadium 23? According to Disney's site, and Citysearch, it's playing there. Might not be IMAX though (I'm in Austin, and dunno anything about the theater).
Yeah, and as an example of code that used to be under the GPL, but is now under a non-GPL license, see Ghostscript. Older versions (pre 2.6?) were GPL, but the recent versions are under some Aladdin license. The GPL version (GNU Ghostscript) is still being maintained, albeit rather slowly.
Also, Aladdin recently had a run-in with the FSF about including hooks for readline support into Aladdin Ghostscript. An excerpt from the build docs:
Aladdin Ghostscript does not include an interface to GNU readline. A user contributed code for this purpose, which we spent significant time debugging and then updating to track internal architectural changes in Ghostscript. The contributor was willing to assign the copyright to Aladdin Enterprises, and to allow the code to be distributed with the Aladdin Free Public License (AFPL) as well as the GNU License (GPL). However, even though the GPL allows linking GPLed code (such as the GNU readline library package) with non-GPLed code (such as all the rest of Aladdin Ghostscript) if one doesn't distribute the result, the Free Software Foundation, creators of the GPL, have told us that in their opinion, the GPL forbids distributing non-GPLed code that is merely intended to be linked with GPLed code. We understand that FSF takes this position in order to prevent the construction of software that is partly GPLed and partly not GPLed, even though the text of the GPL does not actually forbid this (it only forbids distribution of such software). We think that FSF's position is legally questionable and not in the best interest of users, but we do not have the resources to challenge it, especially since FSF's attorney apparently supports it. Therefore, even though we added the user-contributed interface to GNU readline in internal Aladdin Ghostscript version 5.71 and had it working in version 5.93 (one of the last beta versions before the 6.0 release), we removed it from the Aladdin Ghostscript 6.0 distribution.
Stuff like that is why I'm not a fan of the GPL... however, I hope Carmack puts the smack down on this Slade character:) His trying to weasel out of the GPL is majorly lame...
Unfortunatly, if he can make this hold up in court (if it gets there), then the GPL is screwed and we can all pretty much kiss the Open Source movement goodbye.
Open Source was around before the GPL, and will remain even if the GPL falls. See the BSD license. (Of course, under the BSD license, someone could make changes withhold the source code if they wanted)
I stand corrected. It's one of those fat-soluable substances, popularly used in tanning pills. I've seen people who got carried away with taking them and wished they hadn't.;-)
Actually, I'm pretty sure it's water-soluble:) However, vitamin A itself is fat-soluble.
I don't actually know much about PDF (but I do know enough about PS to write simple programs), but I was under the impression that PDF is a subset of PostScript. From what I've heard, PDF is basically the part of PS that actually draws stuff--none of the programmability of PS.
There are wireless repeaters... just about all companies that sell 802.11 cards also sell "access points," which is basically a repeater and bridge to a wired Ethernet. And even if you don't have one of those, you don't need to add more NICs for each wireless user... you only need one wireless NIC in the server. Anyways, I just got a Webgear Aviator2.4 yesterday... pretty cool:) Using it with NetBSD, BTW...
Uh, the only common non-ISO CD format is Macintosh HFS. I suppose some homemade CD-Rs might be in UDF format, but the majority of discs are gonna be in ISO9660 format.
It's also for networks (Ethernet, including Gigabit Ethernet, ATM, SONET, etc...), high performance disks (Fibre Channel), digital video (Firewire, even VGA video ports), and probably many other things.
If you use the same O.S., the same C compiler and libraries, and JUST change the CPU, the Pentium outdoes the Alpha.
You can't keep the same C compiler and libraries while changing the CPU... If you mean use gcc on the Celeron and gcc on the Alpha, that's not very fair. As others have mentioned, the compiler makes a big difference... gcc doesn't do a good job optimizing for the Alpha. It's not unusual to get a 2x speed increase by switching from gcc to DEC^WCompaq's compiler.
Alpha's strength is floating point... try running a raytracer like Povray or something on both the Celeron and the Alpha (or if you want to be boring and forego the pretty picture, invert some big matrices:).
A couple months back, Compaq had a deal where you could get a DS10 (466MHz 21264) for $3K. Certainly not as fast as the XP-1000, but not a bad price. Looks like the price is up to $3800 now...
Previous generation PC164 motherboards were (maybe still are) selling for around $250, including a 500MHz 21164A. Just add an ATX power supply, case, 4 or 8 72 pin parity SIMMs, a hard drive and you have yourself a computer:) (I guess video and network would be nice... it's got ISA and PCI slots). I got myself one of those in May:
PS and case: $60
4 32MB SIMMs: $260
2 gig Quantum Atlas I (fast wide): had it lying around
Symbios 53c875 UW SCSI card: $65
generic Trident PCI SVGA card: $15
D-Link DFE-530TX 10/100 ethernet: $15
I've got mine running NetBSD... works great:) Recently got another 4 32MB SIMMs (they were like $45 a piece) for a total of 256MB. It's slower than the latest x86 stuff out there, but not that much slower... and don't forget, this motherboard came out in like 1996 or so.

X is/was open source.
Windows 2000 does it too... but it's not GPL'd, and it's from Microsoft, so maybe a lot of y'all do mind :)
