some areas just don't have good communities.. and that's unfortunate.. because it takes community knowlage to do any kind of complex tasks, windows or *NIX.
The U of MN has a great community of windows people who actualy know what they're doing.. if you google for "disable lanman" the first thing that comes up is a U of MN security document for setting up windows without old (easy to crack) lanman hashes.
We also have a fairly good linux communit, www.tclug.org. We used to have beermeetings.. but the people who organized it lost interest.
The first iteration of my web/mail/whatever server was a DEC PC 150, 150mhz alpha.. 64bit, with lots of ram and disk space (for the time).
I got the thing back in 1998, some idiot brought it to a computer renaissance (used computer place) and the even dumber sales people bought it as a trade-in. I don't know where it came from, but the sales guys were very confused when the win95 disks wouldn't boot. ha!
After a lot of pain and trouble trying to get some of the system utility software from Compaq.. (god damn EISA utilties) I got the thing up and running with redhat 5.2.
I eventualy retired the box, it was starting to die. I "upgraded" to an AMD K6-300, which is still in use today (not in it's original task).
So in the 4th iteration of nerp.net, I've got a nice new dual Opteron.. and unfortunately, Debian for amd64 (pure64) is still not a production usable state quite yet.. so I'm going to continue to run i386 for atleast the short term on the box.
maybe when I get the extra cash to break the 4gig memory limit on the box, it will be ready.
yep, we sold one of our cars about a year ago, both of us normaly bus commute to work, but on the odd-days like yesterday where I had to go pick up some hardware after work, I could just drive.
we havn't had a situation in the last year where we were totaly in need of a second car. sometimes it is a little anoying.. but that doesn't justify the $400+ a month it costs to own a decent newer car (like my 2000 VW Jetta)
the problem is not that you couldn't get the processors, the problem is scale.
A system like this will use a high-speed interconnect, not gige. The popular choice right now is infiniband, and that stuff isn't cheap, and also has limits to the number of ports per IB switch. The system at LLNL has 4 procs per node, which reduces the number of IB switches involved. 5000 dual proc (you suggest 248 proc) machines would require 2500 IB ports, instead of 1024.
now if you considered the opteron 848 ($1300), in 8proc nodes, that would be something to think about, reduce the number of IB ports in half, and be able to double the processors.
the other consideration is also processor scale. the 27% per CPU is signifigant, because even with dual proc SMP, you loose some % of the CPU time. There was a posting on an article about how processors scale this way. I forget how the principle works.
now with volvo, you get noticed for having 1M miles on your car.. I saw lots of cars in perfect running condition in finland with 300k or more miles on them. Then again, in Minnesota, they salt the hell out of the roads in the winter, so you're lucky to have an underbody after 10 winter seasons. Finland doesn't salt roads, you are required to have winter-tread tires instead. Then again.. Nokia was a rubber boot/tire company before they did cell phones:)
My grandma is running Debian/woody on the machine I setup for her.. I locked most of her config files so that no matter what she does, it will not automaticaly save session information.. so if she messes it up, she can just reboot.
I setup 4 icons for her to click on.. OpenOffice 1.0 (writer), Mozilla, Mozilla Mail, and a button that does a shutdown -h now.. that's it..
I also setup the system with diald, so she doesn't have to figure out how to startup a ppp session.. works great.. she only calls me once a month about "problems with the computer" which always mean, something she forgot, and is doing incorrectly.. like when trying to click with the mouse, highlighting text in OOo, and then typing over the top of whole paragraphs of text.
Yep, the F90 compiler is probably the most important thing on my systems. The only other major pice of software that everyone _really_ cares about is MPI libraries.. and those are compiled with F90 as well. (along with C/C++)
We wanted to license SuSE for a 16 processor machine. A commercial license for SuSE was $4000 (4x 4proc $1000 license), EDU license was much cheaper, $400. It took 2 weeks to PO a SuSE vendor who supported EDU pricing.
After installing the system with SuSE and running their update utility, the new kernel installed by the utility doesn't boot, even after contacting SuSE enterprise support, they had no answer, except to boot the old vulnerable kernel.
RedHat EL was $50, and we downloaded ISO's the same day we paid.
The Cub Foods in MN refused to use loyalty cards, and over 6 months ago the Rainbow Foods stores droped theirs. I guess they just weren't as usefull as some marketdroids thought.

SPF removes the posibility of From: spoofing, by publishing a list of valid servers that are allowed to send mail for the From: domain.
try this command: 'host -t txt aol.com'
You will see a list of valid servers, and "?all" says, be warry of other servers. If it said "-all" it would be block alll servers not listed here.
The big huge major drawback to this system is email forwarding and aliases. The example I like to use is.. I subscribe to debian-devel@debian.org to an email account, and then that account forwards to my home server. The mail would bounce because the email came from a server not in the debian.org approved list.
The solution to the forwarding problem is header-rewriting. When a.forward or alias is processed, the From: is changed to the email address that recived the mail. This will require as much work as the work to eliminate open relays has been. and it may never be 100% until the standards are officialy changed, and vendors change the default settings.
A woman I know _has_ a giant vagina made out of cement in her back yard.. I have pictures (analog) somewhere of my girlfiend and her hanging out.. there's a fire pit in the middle.
I took my NetMD on a trip to europe, I used it while on the plane, and some train trips around Finland. I took 2 NiMH AA's and only used one durring the 2 weeks. It was slightly more bulky than an iPod tho.. I took a small case with 10 LP2 disks.. that's about 2gig worth of good quality mp3s. (20 CD's worth of music) The bonus for NetMD is that 10 disks, and the player/recorder were only $150 or so.
Probably, I've had mine in my office for a year and a half. I adjusted it once when I got it. Havn't thought about checking the adjustments since. I also weigh 175lbs.
I've got one under me right now.. and the fabric back is great for removing heat.. I keep a blanket on mine because otherwise I freeze my ass off. They're not bad.. I do prefer older 80's style desk chairs because I can sit cross-leged in them. I guess sitting normaly for 6 hours of the day is probably better for my back.
Rather than use it for 24/7 power, I would love to have something like this as a backup power source for my ISP stuff, or for my house.. it's mostly solid state, and the fuel is easy to get. For backup power, simply using a H2 tank would be also good.. I wonder how well this thing would scale up to the ~10kw I need to power the server room.
I wasn't out of work at the time, so this doesn't compare as much, but the changes you suggest are good.. I don't think any company has the right to say they own everything you think about. I got a decent offer from a place a few years back, but being a Sysadmin makes this kind of thing totaly not worth dealing with. I told the company to shove it, and went back to looking around.. I work for a university now, where I'm encouraged to expand my skills for my betterment, not just the job.
Nah.. there are a bunch of demo servers with lots of newbs on them.. and the game isn't very complicated.. except for being the team commander, which takes a bit of trial/error to learn.
I've been playing Savage a bunch recently, it's a great combo FPS, and RTS.. I saw it at Best Buy for $20, and after playing the demo.. what a deal. (the demo is a bit bugy, but fun, the retail version update 2.0 fixes all the previous bugs)
I have had several IBM thinkpads, and never had trouble getting repacement parts.. ebay has lots of parts like LCD's and such..
I spilt some booze on my TP21 a while back, it was a bit spendy, but I got a new keyboard direct from IBM parts for $75. it was actualy nice to have have a new keyboard, types much nicer than the original one did.
