The transformers will produce heat, but not usualy require heatsinking (unless the supply is overloaded to begin with). The active components will dissapate much more energy for their package size and require something to channel the heat from them (heatsink). The key is layout... most monitors are convection cooled, as well as computers like the slot loading iMac. They don't seem to have a problem with transformers getting too hot, and have tackled the no fan problem.
Power supplies on the market these days are all of the switching type, not the linear type. Switching power supplies are more efficient, but you still have to regulate voltage, and the components that do this are not 100% efficient (the more current you draw through them, the hotter they'll get). You could in theory build a suitable switching power supply with no fans, but have you opened a modern power supply? They are very cramped, not leaving much room to apply liberal heatsinks to the components that need them (most everything active, like the switching transistors). The quick fix? Blow air through it and use smaller heatsinks.
It is a damn tube which carries light. You are right. When we are talking about a $5 USB cable, are we comparing digital bandwidth? Digital audio signals are usualy PCM encoded or encoded using something like DD (AC3), DTS, etc. This has a limited fixed bandwidth, and is not very demanding in its own right. As long as the decoder can find the clock and sync on it, it has a pretty good chance of finding the signal intact. Poor quality cable CAN make a difference, but its not the limiting factor in most audio installations. But once you have a pure Rotel/McIntosh setup going to your 6 B&W 801s (DTS EX), you're running out of things to replace (which confirms your views). It is not the first thing I would replace (BTW, a small piece of coax with RCA jacks, or even a suitably thick RCA cable will work just fine as a digital coax connection).
The big cable quality issue comes when you go for analog audio. I'm not saying a pure silver $20/foot cable is going to sound better than a silver coated $7/foot cable for line level audio, but it WILL sound better than a 10 ft copper wire about the thickness of mechcanical pencil lead (your average RCA cable). There will be a difference between 22 gauge speaker wire (the thin stuff) and 12 gauge speaker wire (reasonably price at home depot). There is a difference between a low end Kenwood receiver (ick) and a high end Denon receiver (or anything priced higher). And lets not even try to compare low end speakers (Bose, Sony, etc) with high end speakers (B&W, Martin Logan, Paradigm, etc). You do get what you pay for... But there is a nice "value" level, where the next price level doesn't seem worth it.
And it carries signals using light (lets say amplitude). This can take time to change state from a 1 to a 0 and vice versa, making it analog as well. In fact, anything digital is simply strictly interpreted analog signals.
I mean, you'll meet people who say that the quality of your DIGITAL audio cable matters - as if a cheap 3 ft piece of fiber will somehow lose bytes, but an expensive 3 ft piece of fiber will get all those bytes there intact.
For that matter, why do we bother using Cat 5 cable, since we all know barb wire works just as well... I mean, it conducts electricity, right? Also realize that audio has no checksum system, it cannot retransmit audio frames like ethernet can. Jitter is a real problem on digital audio cables (and is usualy higher in optical systems, due to do added conversion process).

Damn, now I'm going to have to watch Two Towers like 5 times until I see that scene... great way to get me to spend more money:-/
I have a credit card from AMEX and a checking account at WAMU, both of their online banking solutions have absolutley no problems. AMEX is also nice in their ability to pay bills from a bank account without bothering to have any paper bills (you can tell them to stop sending you paper statements, but I still prefer to receive them).
I got fed up with most of my stock case fans which had all sorts of problems with noise and their bearings. The heatsink fan was the worst, basicly wobbling around setting off an audible vibration in the case (ThermalTake 6CU fan, replaced with 60mm fan on second link). I replaced every 80mm fan in my case with these:
Panaflo fans are great quality and super quiet (at the expense of some airflow, but most likely you won't need it). I can't tell you about the bearing life of this fan, but I trust the Japanese built "Hydro-wave" bearing fan much more than a cheap chinese "ball bearing" fan.
Sounds like Cisco. Its a very strange solution... There are lots of "call Cisco before fiddling this knob" knobs throughout the interface. And the contracter that installed it at our former school was incompetent, so doing something like running multicast ghost caused the phones to completley freak out (different VLAN mind you, maybe they hadn't heard of the bandwidth reservation/QoS feature:)). They'd start rining randomly at times, but no connection on the other end, amongst other problems.
You could quite possibly sign all of the documents on your site. But the biggest problem really comes down to dynamic sites... how do you implement those successfuly?
iPhoto is a wonderful application for its rather small feature set. Sure, I would like better photo editing controls in it, but I guess thats the price of pure simplicity. iMovie is similar. While it has a higher learning curve than iPhoto (non-linear video editing is not exactly well known), I've seen people go from randomly clicking around the Dog Wash movie to importing and editing their own video footage in the span of a few hours. Its great for a high school video class, where little instruction has to be given on the editing system, so more time can be spent on filmmaking techniques, camera movements, and the like. Way to go Apple:)
Well, its been ages since I've had the oppurtunity to play with an AIW, but its a nice feature. Now, if TiVo had a keyboard, or a way of exporting an index of your recorded programs.... but thats just wishing:)
Should you be interested in a particular word or phrase from a captured show, you can search the close captioned database and playback will begin at the section of the stream.
That feature makes my day:) Kudos to ATI for adding something useful to the video recorder program.
Not exactly a "device", but FreeBSD is still lacking journaling filesystems.
Do your homework. Its called soft-updates. Its not journaling in the same sense as ReiserFS is, but the end result is the same. And yes, its enabled by default for any new file systems that you create as of the past few releases.
yeah, I admit, it wasn't painfuly obvious to click it (even though it usualy said "click the lock to make changes")... but whatever:) Its better than running as root all the time.
If you want a good example of what you're suggesting (ask for admin password), look at Mac OS X. Need to make system changes? Click the lock, enter your password, and the control panel app now runs as root.
Remember, editor != reporter. Being an editor is a much more prestigeous job (especialy being a NYT editor). Editors edit what reporters send them. They are the filter for what goes into the paper. The editors write things themselves, those are called editorials. This link is an editorial. The editorial can be thought of as the opinion of the paper, as the editors have control over what is in the paper. This is not a fact based article by a reporter (those seem to be in short supply at times). This is an opinion. This is a pretty big statement.
There are some more expierimental queueing systems for altq, but if you stick with CBQ, RED, and/or HFSC, you should be fine. ALTQ is actualy part of OpenBSD which is a nice touch (and gives it an stamp of approval on stability and such).
This tips sheet is pretty much the most helpful piece of get started info. If you can get ALTQ in your system, then I would personaly start with Section 2.1 (hint: don't bother adding it staticly to your kernel, the klds work fine).

You say you need a HIPPI card... I believe I actualy have one laying around here. E-mail me if you're interested.

The story body isn't worded very clearly... Jan 17th is the anticipated release date of 5.0, not 5.0RC2

In other news, Panama is back to using ip addresses to look at websites since DNS is now blocked in that country.
Its probably trying to write the output to the same location as the input, namely the CD.
If you actuaky read the interview, pf appeared in the 3.0 release. Which is about a year ago.

Thats because in the new cores its disabled on the silicon.
