The tech specs mention that it's a service and doesn't require any hardware at the school. They even allow an outside ASP. Heck,.mac costs 10-15 times more per year.
I think that puts your comment in a different light.
Hey, you're right, and the wonderful LVM documentation even has a Recipe for performing the backup. I assume that since the snapshot is read-only, dump should work fine without the issues Linus mentioned.
The snapshot partition just has to contain enough space to hold the changes made to the original volume while the snapshot exists.
You know, I was thinking about the same thing since I had problems with a recent restore from a compressed dump archive. I was missing some files probably because I ran the dump from an active file system.
I found out that solaris has a very interesting command: fssnap
It creates a read-only snapshot of your filesystem intended for backup operations.
You create a snapshot, dump the snapshot, then delete the snapshot and the dump is consistent.
I wonder if there's something like this for linux...
Well, my experience up to the 6502 was with processors that had a lot more opcodes in their instruction set. The 68000, z80/8080, 6809 all had separate ADD and ADC-type instructions. (I won't even touch on 370 BAL, which had one-to-one constructs with fortran code)
But the 6502 was SO minimal. They didn't bother with *any* fluff that could be cut out.
Yeah, but you have to clear the carry (CLC), *then* Add with Carry (ADC) to perform what a normal ADD would have done on other processors. Struck me as funny when I first learned 6502.
Actually, a lot of toasters nowadays ARE electronic.
Just as an example, take a look at http://www.sears.com under housewares -> small kitchen appliances -> toasters.
Even if they don't have "digital" or "electronic" in the name, if you dig into the specifications, at least half of them have electronic controls, maybe more.
When I went to school, there was very little Microsoft influence and I did fine too. Of course, the major influence in school at that time was IBM Mainframes, although they had some PDP-11's and VAX's running Unix in the CS department...;)
Sorry, you're right. I calculated wrong. I didn't use the correct formula and didn't add in the latent heat of vaporization.
I just calculated the energy required to raise 1 gallon of water to boiling point, but not actually boil the water. To raise it from room temperature to boiling point takes about 70 cal/gm. To change it from boiling water to boiling vapor takes 540 cal/gm.
If you have a 1-gallon fountain, that's 3.8 liters, or 3800 gm of water. If you have a late-model p4, you're probably dissipating over 50 watts of power (the top-of-the-line p4 is 82 watts) 1 watt = 1 Joule/sec 1 calorie = 4.18 joules so 50 watts ~ 12 cal/sec you could boil 1 gm of water in 50 seconds you could boil 3800 gm of water in 53.6 hours = 2.2 days
As for cooling from the fountain, you'd get it one of two ways: radiation and evaporation. I don't know how much you'd lose from radiation, but I don't think it would be as much as evaporation. Each gm of water you evaporate would provide 540 cal of cooling, which is basically the same as boiling it off.
So keep the fountain full of water, otherwise all the water will be gone in 2.2 days.
I usually don't respond to trolls, but this one was marked "Interesting".
As a test for this, I suggest you run your shower with the bathroom door open and no fans for a couple of hours. See if you enjoy things, maybe do this for a couple weeks to see how much mold grows on the ceiling.
Or a simpler test would be to just fill up your bathtub with warm water and wait.
Interesting stuff will happen, especially in winter. You won't be able to see out of the windows - they'll be covered with ice and or water.;)

I have to disagree too. Using the X at the right to close all tabs might be good from a consistency standpoint, but I think it would really cause problems. The thing is - I rarely use close all tabs - I use it more by accident (losing a lot of pages) than on purpose.
In mozilla, the X to the right of all the tabs is really useful and I use it ALL THE TIME. I pre-open a whole group of interesting stuff, then I work my way through it with the mouse on the X. Click, next. Useful and efficient (and I don't get confused by the X).
Having used crummy VGA cables (without the ferrite cores), I can say that 'a very clean vga signal' isn't always easy to attain/maintain, even for short distances.
I've wondered that if domain names are found to be property, would they be taxable?
Then if you had a nice domain name you acquired in the early 90's and some tax guy did an assessment of it and figured it was worth $1,000,000? Could you afford to keep it?
If the "album" requirement went away, artists might be able to release smaller quantities of music more often. This might actually help the creative process.
It's possible a lot of the music on an album is crap because the creative juices started drying up the 3rd or 4th song. But the artists are trapped until they come up with an entire album full of songs.
If they only released stuff they thought was good and immediately got money for it, some things might be different. They might enjoy writing songs more. It could break things up.
This could also help new artists - they would just have to release one song to get cash flow going and start their career.

So I found it amusing.
Of course, when the carry is not set, you don't. ;)
Yeah, but you have to clear the carry (CLC), *then* Add with Carry (ADC) to perform what a normal ADD would have done on other processors. Struck me as funny when I first learned 6502.
The 6502 doesn't have an ADD instruction.
Yeah, and they'd probably want me to Pay Every Time I Eat!! ;)
Yeah, then the problem is that the manufacturers are AFRAID to add the interface because it'd be used for content transfer.
If I had ethernet on every home entertainment component, it would be great. And I'd pay $100 more each.

The safest thing would be to somehow add one of these to ensure that you don't go away for a weekend and find your system has pulled an Athlon ;)
Too funny. ;)

Ok, I'll bite.
;)
My rough calculations for ~1 gallon waterfall say that a 50 watt cpu like a P4 should boil the water away in just over 5 hours.
Not that it wouldn't be aesthetically pleasing...

Why wait for the killer bees to come to us when we can sic them on someone else?
Sounds like we need an infrared interface for the honeypot project now...
Methane too
By the way, "camino" means "road" in spanish.
...or if you just raise or lower the clock.
I believe the clocks on satellites in orbit run at different rates from clocks at the earth's surface.
