This despite she's been using computers in various jobs since the 80's.
And that is actually the problem. At the time the computer systems changed slowly, if at all (major undertaking changing the system), and they were basically told to do things a certain way or things would break.
So Bozeman to Bakken Oil fields is >400 miles. there and back is >800 miles. 800 miles @ 75MPH is 10h 40min. 800miles @ 85MPH is 9h 24min.
Savings of 1 hour 15 minutes, if you managed to keep average speed close to speed limit, which surprisingly is not horribly hard around that area. I live in South Dakota, and there really is not a problem. Almost no traffic and fairly flat and straight roads.
You have never driven in the US midwest have you... (Or most of the rest of US outside cities). Distances are ridiculously huge, and roads are usually nice, wide and straight.

I do design of some telco electronics, and we only use tantalums. After we figured out you have to double the voltage rating, we have not had a single tantalum failure in 6 years. Before then we had a few flashy failures.
Think you're mixing up your percentages. E85 = 85% Ethanol (15% gasoline). There is no such thing as E90. You are probably thinking of 90% Gasoline and 10%Ethanol (also known as E10).
This particular school district has 300 students. So $50.000 divided over 300 students is $167 per student, not exactly pocket change (or if it is, I'd like to be where that is pocket change).
in 0x00000003, 0x00000002, 0x00000001, 0x00000000, 0x80000000, 0x80000001, 0x80000002..... Huh.... the other one makes more sense (3, 2, 1, 0, -1, -2...) as it would be what you got if you decrement a 32bit int: 0x00000003, 0x00000002, 0x00000001, 0x00000000, 0xffffffff, 0xfffffffe, 0xfffffffd
Which is why, when you do use tantalums, you use ones that are specced at twice the voltage you expect over them.
We've used tantalums in some telecom equipment we make, and except for about 5 spectacular failures (explosions, fireballs) on some early prototypes (because of wrong part numbers and such), we've never seen a failure in almost 7 years.
We could not have used electrolytic caps as they would not have survived as long.
BTW: reverse voltage an electrolyte, and witness the explosion (and foul smell) also.... Used to do that to scare people in electronics class..... Of course, if we redesigned now, I'd probably change out some of the tantalums with ceramic caps.
My family has diesels in Norway (German Fords, 1.8L TDI). Latitude approximately Anchorage AK. The cars have a secondary heat turbine that is used as a engine heater to get the engine to starting temperature in the morning, and to INCREASE the coolant temperature if it is too low.
The cool thing is that this turbine has its own timer so you basically have a mobile block heater with you at all times...
We have a product with about 15 fairly expensive BGA's on it. Before RoHS, we had little to no problems with the board. After we switched, we have a lot of problems with cracked solder joints/BGA balls under the BGA's, and they usually doesn't show up right away, but waits for a few thermal cycles.
The ironic thing is htat since we're making telecom equipment, we're excempt from using unleaded solder, but we cannot get the BGA's with anything except unleaded balls.

Except that the America/New_York timesone info hasn't changed since mid 2006..... Mos of the 2007 tz changes have been DST tweaks for places that didn't decide to do DST until very late (like Bahamas, Pulasky County, Indiana, some places in Canada)
I did this a while back. (3+ years, so it's obviousely not 1TB). My fileserver runs 24/7 and has been doing that for about 3 years (minus downtime for moving).
I use 4 40GB SCSI drives in RAID 5 configuration, using Linux software RAID.(Obviousely I would have used large IDE now, but these were the cheapest per GB at the time, and I already had the SCSI controller laying around) This gives me about 136GB of useable space. PArtition is running ext3 as filesystem.
I have had one disk fail because of a bad solderjoint on the power connector. I had a spare disk put in and newer lost any data (just a bit of uptime), and the array could serve data while it was still rebuilding the new disk.
The CPU is a Pentium II 450 and it has 256MB of RAM. Is running on a Tyan dual mobo with builtin 10/100 and SCSI.
The server is running an older RedHar release with no GUI, upgraded to Kernel 2.6.8.1.
The RAID is shared on the network using Samba.
Read performance is decent, getting around 5-7MBytes/sec read speed which is pretty good on a 100Mbit link. Write speed is slower, around 3-5MB/s
For gigabit, the CPU should be at least a 1Ghz beast, and transfer speed to/from the disks are going to be the main bottleneck.
PS - How do you get back in your car while refueling? Don't you need to squeeze the handle of the pump in the US?
No, on most gaspumps in the US the latch that you can use to lock the handle is still there. In at least Norway these are removed so you can't lock the lever at all (much smarter). If you look closely at the pump handle, there is usually three notches in the handle, and a small hole in the frame. This is where the latch normally goes.
IMHO it is smarter to remove that latch, even if it is convenient to be able to wash the window, check the oil or just sit in the car while it is filling up.

As a H1B, no, you are not eligible for social security.

I have a unicomp model M (typing this). It is exactly like a IBM Model M. I believe Unicom bought the molds from IBM once upon a time.

And that one links to this, which is a new installer that apparently fixes the problem.
WinMerge works under wine (version 2.4.x and 2.8.x at least, 2.6 didn't), and is actually my preferred merge utility under Linux.
But three lefts do...

try this patch (if slachdot lets it through)
will try to read 120GB before writing that to disk...
try:to get the number of blocks the hd contains, and thendouble bs and half count a few times to make the transfer more efficient (as long as it is a multiple of 512 bytes)
It has to be 42!!!
