The Linksys NSLU2 is a home file server which uses USB disks and can be easily flashed with a couple different linux versions. I ran mine with 4 disks in RAID5 and SAMBA, but I'm pretty sure Apache was available as well. It's not very fast and I think the ethernet is 10 base, but it was really easy to set up and I found it reliable. http://www.amazon.com/Linksys-Storage-Link-Drives-NSLU2/dp/B0001FSCZO/ http://www.nslu2-linux.org/
A lesser case happens all the time: just the tests are kept by the teacher. I've been in classes where the teacher hands out the graded tests, but requires it be handed back, and never returned. Is the test my work and property? The teacher wrote the test questions. Is it then his work and property?
Different provider, different phone, different priced plan. But, I figured this will turn into a general discussion of taxes on mobile service. I have a $30/month voice, $20/month data, and $5/month text plan. I'm billed in Garden Grove, CA.

One problem with MDADM is that you'll need disks to be the same size. I'm assuming that we're just going to throw a bunch of disks together and let redundancy take care of the problem of expected failure. You could group the disks by size and run RAID5 on each one with sufficient spare devices, then put the RAID groups together with LVM.
I've been looking at Sun's ZFS a bit lately (I don't think Linux ZFS is ready yet, but it runs on OpenSolaris). It basically does the same thing as RAID and LVM with its zpools. It has the added bonus of checksumming every file and reporting drives with errors.
My own SAN is an NSLU2 with three 500GB USB drives in RAID5. It's slow as it is, but I only use it for long term storage. And it should theoretically scale to 128 devices. Actually, it has two USB ports, so it may be 256, but I'm not sure if each port is its own controller or not.
On the other hand, one cannot be selective about brand protection. If some cuddly organization starts marketing their own brand of Q-Tips (independent of J&J), this dilutes the Q-Tip brand. J&J needs to put a stop to it (in court) or risk losing control of the brand (i.e. anyone can start making Q-Tips [and calling them Q-Tips]).
I heard a funny (and probably fictitious) story by Harry Anderson (the Judge from Night Court). His friend is into chess (belongs to a chess club) and Harry bets that he could beat his friend and at least break even with the whole club at the same time. He watches the first half of the opponents make their moves and then telegraphs them to the other boards which he starts on. To beat his friend he pairs him up with the club champ.
You sure?
http://en.wikipedia.org/wiki/Fatigue_(material)
"In materials science, fatigue is the progressive and localized structural damage that occurs when a material is subjected to cyclic loading. The maximum stress values are less than the ultimate tensile stress limit, and may be below the yield stress limit of the material."
A couple of years ago I heard about Mark Burnett (Survivor creator) trying to put together a show where the contestants would go through Russian Space Camp and the winner would be sent for a trip to the Russian space Station Mir. It was all I could talk about. Friends said they wouldn't fly in a Russian shuttle, but I didn't care. So worth the risk. I don't have money for space tourism.
As for the idea that the show is a cruel hoax: I wish I was in it. At least I could have thought I was in space. The fact that it was fake doesn't take away that it would be great fun. Of course even if interviewed (and British) I would probably have been rejected since I would have been fascinated by the science they would need to make up (gravity generator) and ask too many questions.
For over a grand, I'd expect more thought put into how a camcorder is actually USED.
How about image stabilization? They could put in a metal disk and it would spin. I wonder if they could think of any secondary use for it as well.
Of course the camera would tend to want to roll a bit when you want it to tilt.
JOEL JOHNSON -- After reading the story about Kohei Minato's super-efficient motor, reader Chris Drake wrote in with this explanation:
All Minato's power calculations appear to be wrong (apparently it's a common mistake many scientists make); you can't measure input power using a multimeter when the current drain isn't constant. You can see his workshop in his videos - all his calculations are done using common multimeters and a desktop calculator.
Minato motors use an optical sensor to "switch on" the "stator" (electromagnet) for a fraction of each RPM, so he'd need an oscilloscope and some funky math to figure out how much current the motors are really sucking up (or a stopwatch; and wait for the driving battery to go dead, then estimate based on the battery capacity).
It's still a super neat idea though - which seems to boil down to "drive motors from the outside using aligned permanent magnets and momentary pulses from the stator" instead of the traditional "sick the stator in the middle" idea.
Yeah, I think that was one of the worst things I got from school. I learned to not answer questions in class so that I wouldn't stand out. I do it all the time now in college classes just to move the class along.
Um, at my school we made fun of the drama people just as much. Actually, we made fun of everybody. I'm not sure there is a group you can join and not be made fun of.
I hated this sort of thing, and still do in college. I ended up doing other people's work in my group because it was faster than explaining how it is done to the dumb kids.
It is just frustrating and breeds contempt from both sides.
I got to try one this weekend (Thanks Phil) and learned the coolest thing about the Segway. It uses regenerative braking. So even though you use a good amount of battery going up a big hill, you get a lot back on the way down. Does wonders for vehicle range and power consumption.
Everyone uses the roads. The Monorail is going to be used by a very small group of people and paid for by many other people. I'm all for paying for roads by usage. Like gas taxes.
The monorail won't work. By the Metro's (our bus system) own estimates, 85% of monorail potential riders already ride the bus. So it's not going to take a whole lot of people off the road.
The monorail is being paid for by vehicle taxes. So the people who don't need to ride the monorail are the ones being taxed for it. That's not grassroots, it's socialist.
I bought cable internet without cable television but decided to try it anyway to see if it had been left unblocked. The ONLY chanel I get is Lifetime. It must be a cruel joke.
In general, dry ice tends to freeze a layer of water around itself and greatly reduce its rate of evaporation. I don't know if this is an issue with your 2L bottle, but antifreeze may be able to produce a better effect. Especially for something like a 'witches cauldron' where the dry ice will be submerged. How poisonous is antifreeze?
Sounds like it uses an ultrasonic transducer. It vibrates at ultrasonic levels and produces a mist. Some humidifiers work this way.
A friend of mine used one in a fountain that he made. It was kind of a cool effect because it was underwater pointed at the surface. The surface rippled and mist appeared.

I've always liked the idea of a task based lock.
Not necessarily more secure, though.
A few ideas:
- Play a tune on piano keys (sound off for more security).
- Non trivial math: how many people can integrate sec^3? How many B&E type criminals can?
Any other ideas?On the other hand, one cannot be selective about brand protection. If some cuddly organization starts marketing their own brand of Q-Tips (independent of J&J), this dilutes the Q-Tip brand.

Shouldn't be that hard. I've never seen the word 'pussy' in a medical text.

I got a warning and stern talking to for speeding in Lake Placid, NY. I was on my bike.
"You don't know what you're looking for? Well you should try this!" - repeat to next 100 customers.
No, I'm not big into gay disco; I do work as a DJ and so I know a lot of music. People inevitably request such songs when they're drunk.
I just had to vent about NEW spending.
