It's just not being "sensitive" to LED lights. Most LEDs are ok - most of my lights @ home are LEDs after all. But the front lights of modern Mercedes-Benz'es are horrible - I get sick right away after watching an MB coming towards me. I just can't stand them...
We just finished removing all the water cooling tubing which the old mainframes used.... But hey, don't tell anyone that watercooling big computers isn't a new idea:-).
How about "apt-get install rapidsvn"? The reason people fight getting Debian installed is that they only have to fight once, not every time they want something installed.
Maintain properly?? What maintenance does a CRT require?
I've yet to see a CRT that doesn't require recalibration every 6 months. Grated, I'm anally picky about the quality of the displays I need to look at, but it's a fact that CRT's need maintenance.
Then again, LCD's dim to an uncomfortable level in just a few years, so I'm not sure if they're any better. Haven't tried plasmas yet, so no comment on those.
How to run a computer a sub-zero temps? Place the computer in a really f***ing cold place, connect the cables and fire her up. After about a year the fans start breaking up because their bearings can't handle freezing. Other than the fans, the computer will just run forever...
Don't know whether you're talking about F or C, but it really doesn't matter as they're pretty close to each other near -35 degrees...
I've had my home server sitting outside in a Finnish winter/summer for the last five years with zero problems. Like I said above, the only things that break are the fans, and they probably would have broken inside the house too (because of dust). But since it's cold the fans are next to useless anyway. My server + a three-disk RAID-5 pack have survived ~50C heat (next to no air circulation in that closet) and -36C winter. The only thing I've ever cared about is that if during the winter I take the server out of the closet, I make sure it warms up and dries properly before I put it back there. And I refuse to start the harddrives when they're frozen - so I take the server inside the house, warm it up, make sure it runs ok and then put it back.
So forget all comments about insulation, heaters, remote sensors etc etc - the people who wrote those comments haven't done sub-zero computing.
I bought an used HP LaserJet 4000 + ethernet module for EUR 120 a few years ago and it is the best printer I've ever used (much better and faster than the ones @ work). It prints the first paper in about 5 seconds (including warm-up), cardridge lasts forever in home use (years), supports PostScript for easy netcat printing (cups? bah!) and the feeder easily eats a whole pack of copier paper.
Why buy a new sucky one when you can get an slightly used office printer for less?
I consider myself tech savy [...] I have never built my own PC.
Well, I wouldn't hire you as you're 100% software/OS guy. Building a PC or two is the only way you'll ever learn to fix the real Unix iron you speak so fondly of.
2) Is there ANYONE who has made the switch from postgres to mysql and stuck with it and not regretted it?
Well, I didn't switch. But as a shared server admin who's been running MySQL for years and years, I did take a looong look at PostgreSQL. It had all the features that MySQL didn't have, and that was good. However, the authentication stuff sucked badly, so I retreated back to MySQL for the 50+ users needs.
Truth to be told, the server runs both. It's just that I don't want to create new users for PostgreSQL - I personally only want to deal with MySQL. Another admin handles PG.
Aren't other DNS servers allowed to look at your SOA serial number, notice it hasn't changed, and not bother doing any other work? Isn't that the point of having serial numbers?
I'm glad you told me that - now I can go and take down the setup that has proven to work well....
Yeah, they could check the SOA but they don't. The reason I want all SOAs to be the same is that no matter what, the SOA won't decrease. Basically this setup is the same as the traditional rr dns, but with dead node detection.
It sounds like you are blaming all those other DNS servers for following the RFC.
I'm blaming DNS servers which are borken. The month-and-a-half incident that I was complaining about was about a regular A record which had an refresh time of 8 hours, and an expire time of one week - we changed the IP and increased the serial. After around 6 weeks I finally called my ISP and asked them what the f*ck was wrong with their DNS servers (after which they cleared their cache right away and I finally got the new IP). That was maybe five years ago, so I have no idea whether they have fixed it or not.
This only guarantees DNS HA, since it will not test for apache being alive, or any other service being alive.
True, which is why I called it "simple". But with this setup you only need to monitor local processes and services, and if those die only shut down the nameserver. No need for complicated setups where you need to decide if it was the application of the network that died.
Face it, you do HA if your business depends on it, and would you really want to rely on a DNS hack in that case?
My business, yes, I'd rely on this. I do "offical" HA for living for customers who don't like hacks like this. But that's something I'd personally never use, not even if I'd own a million billion zillion dollar company.
Then again, I suffer from the Not Invented Here -syndrome. Guess I'd make a bad leader: "You'll use my DNS hack or you're fired!":-)
I have an old IBM Aptiva P2/350 in a closet that's open to the outside and has very little insulation and a leaking door. It's been there for the last three years and it's still working fine 24/7 - the only times it's been down have been when the power has gone down.
So, what's so special about this one?
I live in Finland. It's cold here. It has survived weeks of -30C with NO problems. The only things that have borked are a CPU fan (which had no bearings to begin with) and a brand new Seagate hard drive which lasted for exactly two weeks - the replacement has worked fine for a year and a half now.
I've been thinking about replacing the machine with a nice 4U industrial PC that I have laying around - it's just that the Aptiva has proven to work in extreme conditions so I'm not sure if I wanna replace it. Ever.

I'd like to know what you consider "new" then.... Hell, my "new" computer is from 1999...
Well, then perhaps you can point me to a good site detailing how to get Linux running on an RS since I have two in my basement that are just itching to be hooked up.
Try Google. You'll need a special kernel, but the userspace stuff from Debian works wonders.
What a bunch of crap. how old was the RS/6000 and what was the model? how much memory did it have?
It was a 43P-140 with a 332MHz 604e, half a gig of memory. Of course it's slow now, but back then 604e's were standard RS6k CPU's and the 332 was the fastest of them (I know, I worked with SP clusters @ IBM at the time and ALL had 604e CPUs). The Duron was... umm... a 600MHz one with 128 megs of memory (and yes, a few years younger than the RS6k). With the RS/AIX my load was around 40 every day and the machine was unusable - with the Duron the loads were under 1.
I don't know what you do to your AIX machines for them to be fast (neither do the guys @ IBM), but even the POWER4's that I administer now are slow. The floating point performance is excellent, but that's about it. They're no use for any real work - even the Sparcs we have are faster (and they're pathetic too).
Me - I switched to x86 hardware with Linux and haven't looked back.
improved Mach kernels derived from newer incarnations already have shown how powerful and stable the concept can be, Two words:AIX and MacOSX both based on Mach kernels and both excellent and fast operating systems.
I have no idea about OSX, but calling AIX fast is about the same as calling Windows user-friendly. Most people think it's like that but once you actually try do do something the truth reveals itself.
I used to run my own server on AIX on a pretty fast RS/6000 and it was rediculous. I finally replaced it with a slow Duron with Linux which ran abour orders of magnitude faster (and cost about 1/20 of the RS). I also benchmarked Linux on the same RS6k and got 2x the performance compared to AIX on compilations.
If KDE, GNU, and Gimp want enterprise adoption, they would do well to maintain 100% uptime -- appearing to be reliable business-like providers of quality software.
Except that software patents would bring down all three projects. That's why they need to protest - not because they want to annoy people, but because their existence depends on it.
The simply response to the smartest reader, as an Economics major, is why in the hell would I even try to get market share in the first place since I now have a strong fiscal insentive NOT to try to.
It the same as progressive taxing which is in use in most of the countries in this world. I'm surprised that you, as an Economics major, didn't know that. Argue all you want, but the principle is the same: you get punished for earning more money than your neighbours.
What could be useful is - dare I suggest it - holding essential OS kernel files in ROM.
Even easier is to have workstations without hard drives and boot them all from a central NFS server. Configure the export to be read-only and the NFS server so that it cannot be exploited (no route to net). As an added bonus you can turn off the workstations without shutting down (no fsck needed), no drives making noise / burning watts and less maintenance since individual workstations don't need to be installed.
When configured that way the workstations are not only virus-proof, they're kidproof too.
Once again, it happened... Put an empty machine on LAN, install Debian, download 2.4.21. Compile and install new kernel, then install Links to read news for a few minutes before the machine goes to production.
While reading news notice that a 2.4.22 was released. That was like... 10 minutes after downloading and compiling 2.4.21.
I'm afraid to even try compiling 2.4.22 now as 2.4.23 would surely be released before the end of the day........ then again, I wonder how long the kernel guys could possibly keep releasing new kernels while I'm in a middle of compiling the previous version.
Back when computers commonly had 4 megs of memory and MS-DOS, Gravis UltraSound was the k3w1es7 sound card to have. The nice thing about it was it's build in sample memory; base model had 256 KB's but you could upgrade it to a full meg.
Well, someone got bored one day and coded a ramdisk driver for MSDOS and GUS so that you could use the extra ram (games were only using the lowest 256 KB's) as an ramdisk.
I remember downloading that driver from an BBS back in the day; it worked ok, but since I rarely used more than a meg or two out of my 4 megs anyway it wasn't of any use.....
