Last CS test I took(~6-7 years ago) didn't allow pseudocode, We had to write it in syntactically correct Java. Points off for missing brackets/semicolons/etc that would make the code fail to compile as written.
Idle CPU uses less power. When CPU idle time is lowered, that directly translates into additional power consumption. Remember some high-end CPUs have TDPs of 100W or more at full tilt. Now take a whole datacenter of those, decrease their idle time by 25% and you'll see a substantial increase on your power bill.
Newegg prices I was looking at last night (from memory, should be pretty close though):
Motherboard - $55 (Gigabyte Socket AM2 / Micro ATX, onboard NVidia 6100 video) CPU - $30 (Low-end AMD Sempron AM2, plenty for Myth) Memory - $30 (Corsair Value-series 1GB DDR2-667) Hard drive - 160gb = $52, 320gb = $74, 500gb+ = $100 Case - standard minitower is $25 at the local store; decent slim cases seem to run about $50 DVD-ROM readers are $17, $30 if you want a DVD writer.
Hauppauge PVR150 tuner - $59 (make sure you get an analog PVR150 and not the new HVR1600, there aren't any Linux drivers for that one yet).
Little hint for people who get a huge bill for text messages or call-time overages: call the cell company and see if they'll retroactively switch you to the unlimited text plan or a calling plan with more minutes for that month.
I've personally done this with T-Mobile (had a little mishap with a Nagios network monitor sending me a few thousand notify messages by mistake) and it was a great relief to watch my cellphone bill drop from several hundred dollars to the usual $50.
I think the trick is, you have to do it before the next month's bill comes in; that, and T-Mobile has consistently been the least evil of the cellphone companies I have to deal with. If you're on another carrier, YMMV.
IDE CD-ROM drives have always used SCSI-ish commands over the IDE transport (ATAPI). SATA can emulate the IDE layer but it would seem performance is gained by skipping the emulation and going for a more SCSI-like approach directly. Accordingly, in relatively recent Linux kernels SATA is handled via the SCSI transport layer: SATA hard drives show up as SCSI disk devices/dev/sdXX, and CD-ROMs as SCSI devices on/dev/srXX. I'm not entirely sure how Windows does it underneath - I've seen some chips use "SCSI host adapter" drivers, while others use (emulated?) IDE-style storage controller setups with a bunch of "Primary IDE channels".
If a SATA CD-ROM drive looks like SCSI instead of IDE to the system, I'd imagine some copy-protections would get very confused and ignore the drive they don't know how to intercept.
HP isn't the only one that publishes service information for their machines. For example, here's the service manual I've been using recently for Dell Latitude D620s at work: http://support.dell.com/support/edocs/systems/latd 620/en/SM/index.htm Of course, similar manuals for most of their other models are on the website as well.
Now Apple, on the other hand, is usually pretty tight-lipped about how to dismantle their machines, especially the notebooks and the Mini. Not that you still can't find the service manual PDF if you know where to look...
You already do. The backlight inverter in the LCD screen produces several thousand V(rms) initially to fire up the fluorescent tube, and somewhere in the high hundreds of volts while in operation.
Digital cable (the channels above 80 or so, usually) is made of MPEG2 encoded streams, usually with an encryption layer on top; your normal tuner card won't be able to see these. Your options to record digital cable are:
use an external cable box, with either an IR blaster or serial cable to send the channel-change signals. Sometimes you can get a firewire stream from the cable box instead, that depends on your local cableco's equipment.
grab a PCHDTV card which will be able to tune in only unencrypted streams. Check the HDTV forums on avsforums.com to see what streams these will be in your area. In my area, it can pick up the rebroadcasts of the digital air-broadcast channels and that's about it.
this is the I-don't-think-it-exists option: find a tuner card that supports the CableCard standard and will output an unencrypted video stream MythTV can work with, which is highly unlikely and would probably give most TV and movie content providers a heart attack if they knew about it.
Slackware 11's due to come out any day now, so I'm basing the following on that: 2.4.33 is still the actual default, as in "press enter on the bootloader and don't select a kernel when setup asks you to" default. For initial boot and during setup, you can pick the huge26.s kernel if you want it. It's a "universal" build that should support most everything without modules... the source and modules are in/extra if you want them.
I just found this a few minutes ago, and it looks pretty cool. ISBN DB lets you feed in an ISBN via simple HTTP GET and it sends you an XML-format file with all the important card-catalog type information about your book. It wouldn't be too hard to combine that capability with a little script that'd read the ISBN barcode from your barcode scanner, download+parse XML, and save to a MySQL or other database. You'd still have to manually enter location data (shelf number or however you decide to organize things) but it'd save you a lot of time typing author/title/date/etc.
Novell via eDirectory does have the capability of restricting login access times, according to the management interfaces of NWAdmin and ConsoleOne. I've never tried to get it to talk Kerberos, though I imagine it'd be possible.
Gotta love Microsoft and their insanely odd policies. Here's another one... at work, we have one of the site license agreements that allows employees to install a copy of Office on their home computer for work purposes, and we pay extra for the privilege. Except in the last version of their license, they changed a few things - now the only legal installation method (that's at all workable) is to have people bring in their whole computer to work. But they have to install the software themselves, and we can't touch their machine except to put in the CD key which they can't watch us do. Has to be installed from official MS media, so no chance of adding a setup.ini for keyless install, sorry. Oh, and their new Office 2003 Service Pack 2 disc (where we can't use the old ones due to some MS patent conflict) doesn't install FrontPage, and that's what most people want our Office for.
Anyway, for your situation, this sounds like a job for a tool like Autopatcher. Install your copy of non-service-packed windows, install Service Pack 2 from a CD, and then install/run Autopatcher. It doesn't do any slipstreaming, it's just a package of post-SP2 hotfixes with an automated installer, so it shouldn't get you in any licensing trouble. Additionally, it comes with some of the commonly-installed plugins (Flash, Shockwave, Java, etc) and there's a facility for unattended automatic installs of the whole thing.
And because I'm dumb and don't preview, here's the fixed link....
This thing's a pretty versatile device for under $100. Load OpenWRT on it and you'll have a capable Linux machine/distro suitable for small-network routing and firewalling with iptables, vconfig and brcfg. The built-in Ethernet switch is 802.1q VLAN capable and configurable at the per-port level, so you can split the network in two and still have the 'router' connected to both and handling Internet traffic with some modifications to the startup scripts and dnsmasq config. Sounds like a fun project, in any case.

Here's a HDCP remover box. You knew somebody was going to make one eventually. Uses the same HDCP/DVI decoder chip that goes into TV's, just instead of blasting the signal out to a tube/DLP/whatever it outputs a nice unencrypted signal right back to 2 DVI's. There'll be a HDMI-cable version soon I bet... if not, adapter cables are all over the place, HDMI and DVI are pin-compatible for video signal.
If the house burns down (due to electrical something), and they find any evidence that there was wacky out-of-code electrical wiring going on, whether it was the cause or not, then they'll try to deny the claim right off.
Yeah, but epinions probably won't give you reviews based on optics quality, software/driver interfaces, repairability, or alternate-OS support... unless you're looking for recommendations based on things like "I like the color, not too beige but not grey either" or "it was so hard to install, I couldn't find my BSU[sic] ports anywhere" as I've seen on reviews for several other devices.
At the top of the mountain there's a flag, what's left of a campsite, and what appears to be humanoid remains; it's the base camp/monument of the first dwarf explorers who made it to the top.
Kinda surprised you didn't ask about the airport, "under Stormwind," Zul Gurub, Hijal, Caverns of Time... there's a bunch of them.
Anecdotal evidence, sure, but we just did a major network where I work a few months ago, all Cisco equipment, a few 6500's, more 4500's and a crapload of 3550's, all PoE-capable blades... when we fired everything up, we lost 4-5 JetDirect cards in old Laserjet 4's. Not sure why, but something about those cards made the switch send out power.
Because some motherboards use the BIOS setup for such things as memory timings, processor speeds, power management settings, configuration of integrated devices like NICs and IDE controllers....

Sure, they're beta, if you want to be picky about it. Probably works just fine - their last beta drivers did.
