I'm interested if anyone here has tried this and if it works.
Alternatively does anyone know how to stop the weekly circulars that I get every Thursday? I've had my mail shut off because I was out of town for a few weeks and my (apartment) mailbox became stuffed with these circulars and they thought I moved. I'm tired of throwing these away every week. I asked the mailman once and he said they "had" to deliver them. How much are these companies paying the USPS to get this junk put into my mail? I was considering wrapping them up some week, stamping them RTS and tossing them in the post office bin.
At least my spammers are well read. The text that accompanied one of my image spams is as follows:

Set up a catchall on your domain. You'll start getting stuff through. Especially the images ones. Some of the newer "make it look like a real e-mail" gets through.
Everywebsite I have gets its own e-mail account, eg. slashdot@myhost.com. One day I started getting spam to site@myhost.com. So I setup in dreamhost to bounce everything to that e-mail address.
Then I started getting flooded with: otehoenut-site@myhost.com cgjwbmkh-site@myhost.com
Google has, thankfully, let me do delete of *site@myhost.com, but for a time I was still getting them.
Unlimited domains, Unlimited E-mails, $8/month. Plus I have a TON of space.
Enough that I'm using it as a backup for all pictures. I have an rsync that syncs all of my documents to their server once a day.
For $8/month it's great. I have all my e-mail hosted there. My catchall gets forwarded to google then bounced back to my main account. So google does my spam filtering for me.
I know the deed is done. But why did you spend the money on ANOTHER laptop? You could have just formatted OS X off of the drive and run XP. (Un) Surprisingly Apple writes some awesome drivers for XP (from what I've seen in the few times I've had to dual boot). Everything I've tried works great: camera, two finger scrolling, etc.
What about those that switch back with out giving examples? I've seen plenty of switches tell us WHY they switched and stayed. Apps crashing, better programs, more intuitive UI.
I haven't met many switch-backers that say WHY they weren't as productive. Could you not find programs you liked? Did OS X do something different that you didn't like?
I don't have a problem with you switching back, it's just the lack of a reason WHY weren't you as productive.
Time and time again I hear about how BMW is making record profits, yet their market share never raises. I don't see how BMW is going to compete with the likes of GM. GM is the worlds largest producer of automobiles.
Despite being profitable BMW should try a different tactic.
Since this is slashdot and everyone wants reasonable numbers, here we go.
First off. Gear ratios are normally specified as 2.3, 2.4. These are meaning 2.3:1. 2.3 revolutions of the engine per revolution of the tire. 1:10000 is backwards.
Find: Gear ratios required to move 200 car train to 100 mph.
Assumptions:
Gear ratio specified is final engine:wheels gear ratio. I'm not going to deal with separate gear rations, final drives and rear end ratios.
Train wheels are 18" in diameter.
Trains are pulling the same freight that goes over the road in those big boxes that move in between.
Gear ratios from a truck 'scale' well to large size. Meaning if 1 semi needs X:1 ratio to move 1 car. Y*X:1 ratio is needed to move Y cars. This is just to get the same amount of torque multiplication.
50% overlap in powerbands. On manual transmissions redline in 1st gear doesn't match up to idle in 2nd. There is a bit of overlap, allowing you to drive for speed, pulling, economy, etc.
Our manual transmission on highway truck for pulling 1 'car' will be a Cat C13. With 1550 ft-lbs.
Our manual transmission locomotive will be running a Caterpillar C3516C
Since I can't find a torque curve for the 3516. We will use HP=Torque (ft-lb)*RPM/5252.
Diesel torque curves are flat for their operating range, 1000-1800 RPM.
Eaton 13 speed manual transmission, first gear 19.7:1.
Eaton rear end ration of 2:1.
Calculations:
HP ~= 500 @ 1000 RPM. Therefore torque is around 2626 ft-lbs for the C3517.
Torque required to get 1 car moving is 19.7*2*1550 ft-lbs=61070 ft-lbs
Torque required to get 200 cars moving is 200*61070 ft-lbs=1.2E7 ft-lbs
If the engine puts on 2626 ft-lbs, the first gear ratio will need to be: 200*61070/2626= 4651:1.
18" wheels * Pi = 56.5 in / rotation.
Speed in First gear at 1400 RPM = Speed in Second Gear at 1000 RPM.
etc
This will allow the 50% overlap for operating in torque bands.
So you're in 1st gear. You're turning 1000 RPM (you finally got your massive clutch pack to sync up). You are going a blistering:
56.5 in / rotation * 1000 rotations / minute * 1/4651.1 * 1 foot / (12 inches) * 1 mile / (5280 feet) * (60 minutes) / (1 hour)=0.012 MPH
By time you're upto 1400 RPM you're now cranking out 0.016 MPH.
So you need to find your 2nd gear ratio
56.5 in / rotation * 1000 rotations / minute * 1/X* 1 foot / (12 inches) * 1 mile / (5280 feet) * (60 minutes) / (1 hour)=0.016 MPH.
Solve for X.
Second gear ratio is 3320:1.
Etc. I set up a spreadsheet to calculate all the gears (With much help from my TI-89 to get numbers). I published it through google docs here: "Manual Transmission Locomotive".
So you were correct, my hyberbole numbers were completely off. However I think it illustrated the point. A gear ratio of 4600:1 means one gear is going to have 4600 teeth for every tooth another gear has. In addition you're going to need 28 gears to cruise at 1000 RPM and 100 MPH. Not to mention the size of shafts and gear sizes needed to transmit 1.2E7 ft-lbs. On-highway trucks already have multiple clutch packs to get that amount of torque in a small overall diameter. (If you're patient, I could find my machine design books and I could calculate the number of clutch packs given an overall radius 1 ft/clutch. Heck I could run the numbers required to get the gear sizes to transmit the torques)
Plus you bring up tons of feasability issues. Braking would be quite difficult. Most locomotives use EMF braking. They turn all their electric motors into generators and dump all that energy to a grid. I suppose you could install a compression brake and make the engineer downshift thr
Because the diesel/electric motors in trains aren't done for efficiency reasons, they're done because of space constraints.
First, trains don't have batteries. It's just: engine->genset->electric motor.
Diesel engines (especially large ones) work within a very narrow power band. For on highway trucks it's around 1000 - 2000 RPM. This is great when pulling a heavy load, but it means that you're gearing has to be set up accordingly. This is why 18-wheelers have 13 speed gear boxes.
With the amount of torque that trains need to get up to speed the gear box would need to be as long, if not longer, than the train itself. You'd need a 10000:1 (made up number) gear ratio to get the train moving, but that ratio would only be good for 1000-2000 RPM, so you'd have to shift to 9999:1, etc.
The genset -> electric motor works great because the electric motor has a near infinite 'gear ratio' and provides peak torque from 0 RPM.
However there are losses, you'll never get better than a drive where the engine is connected directly to the wheels, this is why some automatic transmissions allow you to lock up the torque converter.
Diesel hybrids are coming, but the gains over a traditional diesel engine aren't as great as over a gasoline engine.
Furthermore, they really looked the part, being much closer in appearance than fraternal twins, but being subtley different from identical twins. The Olsen Twins?
Meanwhile, new episodes of 'SG-1' and 'Atlantis' start airing April 13 in the U.S., on The SCI FI Channel.
I understand how the rest of the world feels with everything being broadcast late. SG-1 has been broadcast in UK for some time (Up to episode 20 currently) and Atlantis has been broadcast in Australia.
I can say I won't be catching these on SciFi since I have them all from BitTorrent.
Networks: Start broadcasting TV shows at the same time... because otherwise we're going to get them anyway.
OS X has both. They have an 'upgrade' path where it will leave all your files in place and upgrade system components. They also have an "Archive and Install" which is somewhere in between an upgrade and a full clean install.
I usually do the "Archive and Install" just so that everything gets wiped. However maybe I'll forget to backup my httpd.conf or some other small config file. I usually run for a month and then delete the "Archived" folder. All the programs I installed but never used, everything goes and I find I usually gain a few gigs.
I'm a "mechanical engineer," at least that's what my degree says. I'm considered top talent in my diesel engines company because I can get stuff done. Computer knowledge isn't that difficult to obtain. "ssh -D 1080" (and the putty equivalent). I've written VB scripts and matlab scripts to analyze data that people used to do by hand. To me it's trivial but to my managers it's considered 'best talent'. You'd think that at a biomedical company there would be one or two 'top talent' individuals who were really good with computers that could help analyze results.
