I have several IA-64 systems at work. IA-64 requires EFI (part of the intel spec). It's a major pain in the ass.. you have to have a dos fat formated filesystem to store bootloaders, and other utilities as a primary partition.. besides the fact that they changed the normal dos partition format for EFI. I wish they would have just ported OpenBoot.
I've been playing Savage for the last few weeks.. they have a free 130mb linux client demo download. It's a great game, 3d FPS for up to 32 players per team.. and one person on each team is a commander, who is in overhead view RTS mode. It's a bit warcraft like in the RTS mode.. gather resources, build tech buildings, build spawn buildings. main goal is kill the other teams stronghold.
in the full version, there are 2 races, humans and beasts. There are also more maps.
That's not the point. Once you get users on a windows version of Evolution, OO.o, Mozilla, etc etc.. you can then migrate them off of windows entirely.. windows versions of open source software are usefull to help ween people away from proprietary OS's:)
yea.. back in college, he got up earlier than I did.. or was it stay up later.. my ID is where it is because of my sleep pattern for the day/. opened up for user accounts.
that's the whole point of LIDS.. LIDS provides kernel hooks to add extra level of access restrictions to the root UID. read up on LIDS before you speak.
yep.. it's great.. we have a 48proc altix at work, and we have another one on order. (1.3ghz I2)
Rumor has it.. SGI has 128proc's in beta in their labs. That would match the capacity of the origin 3800's that our Alitx replaced. (we had 2 96proc 3800's)
yes.. this exactly what I did for a small school in my area. We setup squid, and blocked access to httpd at the firewall, unless it came from the squid server. We simply said.. "we are not going to block anything, but we have logs with your name on them to see what you are doing if we need to" Some of the teachers wanted net-nanny software, but I explained to them the flaws in the system, and how it was a social problem, with no technical solution. All students got a NIS login in their lab of linux machines, and there was always supposed to be a teacher in the room when students were there.
I think I looked at the logs once in the 3 years I ran that network.. they decided that the $500/year they spent on my consulting fees was too much.. and probably went out and bought windows to replace all the redhat machines I setup.
it's not separate TLD's, but it is separate network infrastructure.. my university has a 655mbit I2 link through abilene. This connects me to a bunch of other U's, much faster than normal I1 stuff.
I also want to know how much floor space this thing takes up. with 12 nodes per rack, you're looking at 92 racks to cover that many machines.. the picture they posted shows 15+ racks in a row, say they have 22 racks per row, which would give us room for IB switches, gige switches, and disk servers. that's 256 nodes per row.. you're looking at maybe 4.5 rows of 22 24" racks.. the G5 being an 8" wide box. with some extra room for cable managment, and rack structure, you're probably talking 28" wide for each rack. each row is 51.3 feet long, and 8 feet wide (4ft for the rack, 4ft for the walking space).. totals (rough estimate here) 1800 square feet. or 50 feet by 36 feet. That's a hell of a lot of floor space.
With a 44 node racksavers setup, or a more normal 42 1U node rack, you're looking at 27 19" racks to equal the same number of compute nodes. plus 3 racks for IB switches, and another for disks.. so say 31 racks total.. stacked into rows of 10, you're looking at 3 rows 20 feet wide.. again, 8 feet for each row, or around 500 square feet.. or around 1/4 the space..
Maybe i'm just lucky, but my girlfriend is a technical writer at Cray, and she's always cracking some kind of joke.. I don't know if it makes it into her manuals or not.
yep.. I see this too. Many hams I know are not linux/unix users. I also have a hard time finding open source/etc solutions for ham problems. software like radio mobile, echolink, and other usefull ham apps are only available in windows.
When it comes to packet radio, there is a lot more linux stuff going on.. mostly because packet started before windows existed, and the only OS that networked was UNIX.
I keep my HT charged up.. and can plug it into 12v car any time.. Our club repeater has 2 APC's on different parts of the equipment to keep it online for hours. We also have the repeater on a backup generator.
If the power outage had hit minnesota, I'd be 30 seconds away from my radio, ready to find out where everyone is, and what is going on.
Go get a copy of the Nation Electric Code.. and read up a bit.. it's long and boring.. but I just took the minnesota state electritians exam.. and now i'm a certified Power Limited Tech.. good enough for up to 600 volt circuts..
The software that runs on the thing is based on the software used in the Empeg linux player.. the Karma runs linux, and has a usb2 hub, not a client.. lots of hack potential.
I'm working on something similar, with the soekris net4521 board, (same as the one this guy used) but with a demarctech 200mw high output wireless card, for much greater range.
I'm doign most of the work with an old P200 right now.. got that out of a dumpster at a local school. My box does the AP, routing, dhcp, dns, and eventualy i'm goign to try and set it up as a wirewall. the ability to SSH into the AP is very handy.. none of the AP's out there (besides super expensive Cisco IOS based AP's) do that.
I would love to see the ability to change the frequency of 802.11b cards. as a ham radio operator, I can use other radio bands beond the 2400 - 2483.5mhz ISM band, like 2300-2310mhz and 2390-2400mhz
the only issue would be that 802.11b is about 15mhz wide. if this could be re-tuned, we could use the gear in areas where we wouldn't have to deal with normal interfearance.
I don't know why people keep saying "BSD is better than linux, yada yada"
Systems are good for their different needs.
We have a 48 proc/100gb memory SGI linux box here, I don't think any of the *BSD can scale that well yet.
We also have a half dozen FreeBSD machines doing firewall/mail/ops tasks.. those machines do their job well.
Linux will not be "declared illegal", if there is anything in the kernel that must be removed, it'll get pulled out, re-written, and re-released. The only issue will be previous illegal code installs.. It will take YEARS in court to determin if there are any damages to be had, and by the time it is settled, kernel 4.0 will be out, and the problem will have been solved years previously.
1.3. The total transmitter output power per band for any high power entry in any category for an ARRL Contest is either 1500 Watts PEP or the maximum allowable power level established by the national licensing authority of your country, whichever is lower.
the University of Minnesota Ham club will be runing our field day on a 3000W generator we're borrowing from an ISP... we've got a 1500W amplifier for our HF rig, now all we need to do is find a nice big tent to tx from because weather reports say it's supposed to thunderstorm in the morning.. bleh!

I think you're being paranoid and silly.
We just purchased a brand new 48 processor SGI Altix here, and SGI has made no mention of any issues with SCO.
This is all a bunch of hot air, and I seriously wouldn't side track work based on something that hasn't happened yet.
as Linus and others have said.. this is a battle for lawyers to pay attention to, not the geeks.

I agree, x.509 keys are anoying.. having the USPS sign my PGP key would be damn cool..
although USPS would quickly become the center node of the PGP keyring stats.
