The $500 Calibri-133 is a tiny flash disk Linux device. It is intended to be a network tool, but internally it has 2 IDE interfaces. No mounting bays -- maybe you could squeeze a SanDisk in there. Or upgrade the flash disk to 144 MB. http://yulia.com/hardware/index.html
The low-powered laser makes the clumps of Deuterium atoms explode. Some of these energetic atoms collide. Some of the collisions happen to cause fusion.
It's sort of the reverse of the usual laser-initiated design. The most common design involves having the fusion fuel inside a container such as a tiny glass bead. The huge laser blast causes the container and part of fuel to explode, causing a plasma shock wave going both outward and inward. The inward shock wave is what the design uses to actually trap and ignite the fusion fuel.
This table-top design is actually using an outward-traveling blast. By making many blasts, some of them collide in interesting ways.
At the very least, they've managed to use a very low powered laser to trigger fusion. Because these fellows have been wrestling with the megawatt fusion lasers, I'm sure they have some interesting engineering ideas for this design. At least they don't have to produce as much output to reach the break-even point.
With technology this simple (vacuum chamber with laser windows?), perhaps all that's needed is a steel chamber with laser ports...it's easy enough to generate electricity from hot steel.
Yeah. MF Physics makes neutron generators using D-D or D-T reactions. Electronic acceleration with high voltages instead of this story's weak laser beam.
I see that the tabletop experimenters have experience with the big fusion equipment as well, so they do have a good idea what they are doing.
Just ask the Administration and the Legal Counsel about paying expenses to repair machines damaged by intruders, paying for bandwidth being used by outside intruders, and liability for spam, redirected attacks, and servers operated by outsiders.
As others have said, first establish a policy. You cannot enforce what you do not have. Actually, you need separate Administrative and Academic policies. And probably one for the dorm buildings which is more lax (and which compensates for high bandwidth non-academic net use...although a time-sensitive throttle which allows more game bandwidth in evening "low-academic-demand" times might be enough).
Then you can start with implementation details. An Internet firewall and exception procedure is obvious. As these are autonomous departments, each obviously has to be firewalled to protect all from errors within each. Everything else depends upon your policies and implementation.
This is not restricted to Linux. Other operating systems can be victims and sources of attacks (and both if an intruder launches an attack from a victim). Specify the purposes and procedures, not the tools.
That's right. IPP lets you find out the abilities of the printers as well as tell the printer the format of your document.
With LPD you have to know the kind of printer and use the appropriate driver. Or you get a ream of garbage printed.
Some print services don't even allow passwords, while IPP allows PW and SSL.
IPP lets you inquire/change your queued print jobs.
I have been using magic filters, but they are just a kludge. New printer formats can be confused with others. I have been tending to make clients always use Postscript, but IPP will allow more flexibility...and safer configuration by users.
Your Project Design Document is in Word97 format. It will become increasingly unreadable. At least you could print it to a file in Postscript format...while your Word can still read the file.
If the submitter of a story is registered with/., give them 10 moderation points and they are a moderator until those points are gone. For each 25 articles to the story give them 1 more moderation point. Points can be used anywhere.
Successful submitters are people who have found something which has been judged to be interesting to/. and have phrased it in a way which the publisher liked. Let the submitters assist with their topic if they wish, or trust them to use their points in a similarly relevant way.
Sounds like you're thinking of something like GroupLens, a Usenet newsreader which monitors reading habits and scoring. A GL profile is built up for each GL user, and new articles are presented based upon how interesting there were to other GL users. Now reviewing movies.
So only the moderators who wrote over 100 articles have earned moderator points? Prolific.
And here I was just an AC until a week ago because without the/. customization features I didn't want another account/pw for my meager comments...can I reclaim my past comments?:-)

Just buy several different plastic model kits. Chop them up. Glue assorted pieces together into shapes which fit on your head and around the tiny headset. Or for a sleeker look use automotive/plumber's epoxy putty and metal/plastic stock pieces to make a custom shape. Or just buy more tiny headsets and help drive the prices down for the rest of us.
"it was based partly on the ext2fs" OK, in/usr/src/linux/fs/ext2/*.c I see an assortment of copyrights, starting with Linus'. I think all that falls under the GPL which is in/usr/src/linux/COPYING. So if you used some ext2fs code, your stuff is already liberated because it is already GPL. It should be labeled as such to avoid confusion. Check the company's web/FTP site and see if they already put the code there. If they're shipping their product, any customer should be able to inexpensively get the code from them and make it available per the GPL.
The terms to look for are "Single Board Computer" (SBC), "biscuit" or "PC/104" for most small computers. These are intended to be small industrial computers.
Also don't forget the wearable technology. The MIT Wearables and Yahoo:Wearables pages are good starting points. (I don't know where wearables.ml.org went to when DNS failed...)
The Wearable technology often uses PCMCIA-sized motherboards. Those pages have links to most of those boards. VGA/LCD, IDE, and the usual other interfaces are all on that one tiny card. Haven't seen sound on one yet.
Zoneinfo has a large database of time zone definitions. "zoneinfo timezone" seems to produce good results in search engines.
Just look in/usr/lib/zoneinfo on your favorite machine. "man tzfile" might have details. There's also an update recently available. (I refuse to mention a URL, as those who are more than merely curious will find it.. and most people are in one timezone with unchanged rules)

Hey, I was going to say that! Give it back! :-)

The CAF has a collection of academic computing policies here: http://www.eff.org/CAF/faq/policy.best. html

The mods were chosen from those who thought the old /. was worth joining or who wanted their names on their articles.
So GL uses all GL users as reviewers.

I found where Wearables Central went to. See their long list of hardware there. [ The green decorations are navigation buttons without a clue ]
