Keep in mind, first of all, that most motherboards are multi-layered to begin with. I think four layer is pretty common, and a lot of SMP systems can be 6 or even 8 layers (becoming exponentially more expesnive with each additional layer). Utilizing the back side (in terms of traces) would be no different than adding a layer.
As far as having actual parts on both sides, you would increase the clearence requirements for the back side of the motherboard. The overall volume of the casing would probably stay the same, but you'd simply change the footprint (i.e. a taller rectangular case becomes a shorter, but wider, more cubic case).
A while back, I participated in a beta test for Sybase. It was specifically for the Linux release. Ironically, they messed up and emailed the license agreement in Word format. Naturally, many of us complained, and they quickly responded with a PDF fail and apologized for the "mistake."
I did this once for a non-profit research institute. We used Lucent's online text-to-speech page to produce a library of vocabulary, with a patched copy of sox to convert them to the appropriate type (gmr?). We used USR voice modems, and about 300 lines of Perl code to handle everything from pickup, to producing the menu, building phrases out of the vocabulary, reading responses, and spitting out the resulting data. It was a simple menu system for reading off meteorological data, so at least the vocabulary was fixed and controlled.
I'd say it worked pretty well, and making changes worked out okay. For our purposes, text-to-speech voices did the job and saved us from the issues of having a proper studio to produce useful sample.
These are systems from CCI-Triad that are circa the mid 70's. The machines are typically anywhere from full-tower to washing-machine size, and run on a Z-80 processor (original version of what is now powering a lot of the TI-80 line of calculators). They typically have 80-120 MB of disk space on disks with 8" platters, and for backup use 120MB Tandberg tapes. They communicate using bisychronous 3780 protocol to vendors, and use 40-column async terminals.
Where do you find these fossils? Try a very large percentage of auto parts stores! Just look for the ugly blue terminals with "TRIAD" stamped on them.
How do I know? I run the communications systems for one of the major auto parts chains. These damned things are older than I am! Fortunately, we are replacing everything with a new system soon, and putting Linux into every one of our stores (and our jobbers) as a terminal controller/router/desktop!
Using my Yamaha 2100S I've burned on unbranded 8x bulk CDRs and branded 12x CDRs with no problems. I tried to burn CDRW beyond the spec, but appearently the drive automatically downshifted to the burn speed tagged on the CD (2x in this case).
The local Office Depot sells 100 packs of their branded (hence well-laminated) 80-min CDRs for around $29.89. I just picked up two 100 packs the other day. I've had zero coasters with them, and no problems using them in various players (my Pine D'Music SM-200C, ancient 2x SCSI CDROM drives, various standard CD boomboxes, etc).
I've had the same luck with Fuji branded disks (also Taiyo Yuden, I believe). Zero coasters, and no problems on playback in the above devices. Best Buy sometimes has these on sale for around $20 for a 50 pack.
The only disks I've ever really had issues with playback are some old Imation blue (dark blue) disks. Very few devices can read them--pretty much just CDRW drives. As far as quality, I bought some CompUSA unbranded disks once, 100 for around $19.99 and they are crap. They read fine, but are basically unlaminated, and more than half the ones I've used so far (150+) have been scrapped, and that is NOT in an abusive environment.
A coworker recently rebuilt his home office using kitchen and bathroom cabinets, base units, vanities, and counters. They are relatively inexpensive (come on now, you really don't need marble tops and cherry cabinets, do you?), and come in a massive variety of configurations. He even got some full-height pantries to add storage. Personally, I have an okay desk, but I may get some kitchen wall cabinets to add on due to a severe lack of storage space. Hell, I have a good 4 feet above the desk that's unused, might as well put it to use!
I would absolutely recommend the 3Ware Escalade IDE RAID cards. I'm using a 6200 right now with a couple 75GXP's striped, and can pull 50MB/s easily. And for less than $120, it was a great value!
A few years ago, I was paid to run my high school's new internet lab for the summer. This included teaching groups of teachers, as well as summer school classes, how to use a basic web browser. Many of the teachers I taught (talking about turning the tables!) were elderly--most districts are in desperate need of teachers, so many came out of retirement around then.
Believe it or not, the main problems I dealt with were physical rather than mental. Maybe not so unbelievable, I suppose--these ARE teachers, after all. Many of the teachers were sufferers from usually severe arthritis. Hence, they had great difficulty in mouse control.
Be prepared to deal with the possibility of needing to have some large trackballs for some of the people to use--I found they were much easier for some of the more senior students to operate.
I envy you, though. The people you will be teaching sound like they will be there only because they WANT to learn. Try teaching 30 failures (90% of the summer school population I taught) who may be in high-school, but have rejected even learning that 2+2=4, and blocked education from their lives completely. Or have decided they only want to surf for porn. Or teachers that REFUSE to come into the 20th century gracefully.
Look for a series of books by Joel Rosenberg, "Guardians of the Flame". The first book is "The Sleeping Dragon". It is about a group of AD&D players that get pulled into the world their characters were in. It talks a lot about this, how these college students change the world with their knowlege.
At least it's not a terribly grim future they deal with!
That is true for content protection. However, DTV is a service and so the laws are a bit different.
Good point, I hadn't thought about that one. Then again I'm almost tempted to say we should charge DSS providers for the privelege of radiating us continuously with high-frequency radiation =)
It is not "stealing TV". When you steal something, the person that you stole it from no longer possesses it.
Consider the infrastructure. Those satellites are expensive. If you are grabbing the service for free, who's paying
for the infrastructure and operating costs? Hughes is not the bad guy here. They don't circumvent fair use rights in
any way, they provide better service, pricing, and quality than local cable providers and their pay per view is
cheaper than (and higher quality than VHS) video rental. Their business practices are not monopolistic (in fact,
they have several competitors)
Now wait a minute, I agree it is immoral. But you have to keep in mind the legal aspect attempting to push a piracy charge.
The reason you have never seen an individual (someone not reselling their copied/"stolen" material) is because of the need to prove a loss. This is a major issue surrounding MP3's and the like. Just because a person has copied/decoded/viewed commercial data, it does NOT mean they would have ever paid for it. You can NOT prove a loss of profit, because you can't prove that the person would have ever paid for it at all.
Until mind-reader machines become (a) a reality and (b) legal testimony, this won't happen =).
Ad addendum: Such bastardized pieces of legislation as the DMCA appearently could allow prosecution for this. I think the DMCA though, if it ever reaches high courts, will probably crumble.
I noticed a similar thing yesterday while trying to find out why Slashdot's DNS was down (was a bad router in sprintlink).

I'm running Reiserfs+2.4.x over two 60GB drives (no raid, just straight partitioning). Running Sybase, doing NFS-based backups of a bunch of systems, etc. Very, very nice! Use it at home, my machine at work, and the 5GB spools on our print servers.
I got one of these from the local flea market (it was marked as their first production run), originally priced at $45, but I got it for $35. It includes the standard multitool and a pretty good small driver with a few bits. Personally though, I swapped a lot of the bits out with my own collection to get exactly what I wanted.
The knife blades are literally razor-sharp (not always a good thing, mind you, but rare among most of these kinds of tools). The needle-nose meets perfectly, and has no "wiggle" that most cheap multitools have. The wire cutters can handle small wire pretty well, and can cut through thin insulation well (most don't because the blades don't meet together perfectly). It DOES have trouble with the threaded cord in most CAT5, but that's what the razor-edge blade is for =).
Actually, we do have one physically attached printer (the rest are network and on Xylogics annexes) which produced that message quite often! Never shown it to our operators though =)

I really do hope you meant astronomy club. I don't think Miss Cleo will be of much help with a radio telescope.

Not true..Pick up a copy of MPlayer (look on freshmeat). Plays WMV/DivX/MPEG/MPEG2/ASF/AVI and others with no problems at all.
I normally don't write something like this, but I just couldn't help myself this time...
Isn't this like trying to put a combination lock on a cardboard box? What's the point?
Okay, okay...it was funnier when I first thought of it!

Isn't this probably the exact same thing that's been done on diesel submarines for the last half a century?
In which case, you just do a quick "killall -9 httpd" and do the world a great favor.
Yes, this will probably work...they're running Apache over FreeBSD.
