Factor in thinner tires having less air in them (as in, fewer molecules, or the volume of the gas in them at STP). You can take this to an absurdity if you wish - you could have a massive, building-sized tank of N2 at the same pressure as a tire, but the area is obviously different.
I'm not going to argue whether they work better on ice - I'm not exactly living in a cold-winter area, they close the schools if there's an inch of snow on the ground. I have zero capacity to judge whether they work or not. But the reasoning doesn't seem right. I would hazard a guess that it has more to do with the weight of the car being the same, but the contact patch being smaller, leading to greater force on the tires.
We had an entire section on nuclear chemistry. We had to be able to balance a radioactive decay equation. We had to know how fission and fusion work. We had to calculate half-lives. Hell, we did an entire lab using Geiger counters. The textbook even had a few pages, and a handful of questions, on bombs.
All I did was expand on the handful of diagrams in the textbook concerning nuclear weapon reactions. I added the part about the chemical explosives, I added the tritium-boost and uranium shell, I worked out the equations for the main fission products.
And the reason I was able to easily sleep through that class was because I'd taken the same one in high school, but it was unfortunately not for college credits. And for some reason I wasn't allowed to try testing out of it.
When I took Chemistry II in college, everyone had to do one presentation.
I did mine on nuclear weapons. I walked through every reaction involved - the conventional explosives, the plutonium fission, the tritium boost (modern bombs use a small amount of tritium that does not fuse, but acts as a neutron source to boost the fission reaction), the uranium fission (most modern bombs use a uranium case, which is involved in the reaction), the hydrogen fusion.
You should have seen the professor's face when the "end product" of my reaction included an amount of energy measured in petajoules.
Then I played a clip of nuclear test footage, for the people who didn't pay attention to the class. Which technically includes myself - I spent much of that class playing games on my laptop, not paying attention.
The intermediary step is for the *technology*, not the *user*.
Dedicated eBooks have far, far better battery life, and are cheaper and often lighter. That means they work better in many of the use cases for the tech they're replacing, "paper books".
Tablets will eventually be able to encompass those features - they already do, for some people. Eventually. We're close enough that we can see the eReader is just a transitional phase, but it's a necessary stepping-stone.
I moved into the city a few months ago, and brought my old mountain bike as I'm only a dozen blocks or so from my office.
I tried biking into work once. ONCE. By the time I got there, I was so exhausted that I spent an hour trying not to pass out, throw up, or do both simultaneously. And that was only partially because I'm a bit out of shape - the bike wasn't exactly in good condition*, and was built for rough terrain, not light city commutes. And carrying a 9-pound laptop on my back certainly didn't help.
I'm vaguely looking to buy a new bike - one better-suited to urban riding, and with a lot less rust. It's gotten too cold to ride now, though - I'll probably wait until spring.
* The chains were rusted and frequently slipped (once completely off the gears), the forward gear shift was jammed, and the brakes were barely working. Seriously, I would probably have been better off walking - I frequently walk about halfway to the office anyways, to grab a quick bite.
The 3-liter bottles seem to be used by the "cheap store-brand or off-brand sodas". I have a 3-liter bottle of "Super Chill Pineapple Soda" in my fridge right now, and I recall the Food Lion branded sodas coming in 3-liter bottles as well.
I tried running just OS X on my Mac. It jut does not wok for gaming, not just because of poor application support but because of poor OS support.
Roughly 25% of my Steam library has OS X binaries at all, and a significant number refuse to run either due to an "outdated" OS (10.6), or a "too weak" graphics card. And even those games that do run on OS X, often run with some features disabled. For instance, Counter-Strike has no dynamic reflection options under OS X, but it works fine on the same computer under Windows. It seems the graphics drivers, or some other subsystem, of OS X do not have the same functionality of those on Windows.
And you overestimate the difficulty of rebooting, at least for me. My laptop has < 5 second boot times in Windows - I expect sub-second boots in Linux. And the Mac, even without the aid of an SSD, boots in about twenty seconds in OS X and thirty in Windows. And I've taken care to eliminate the normal post-boot slowness on all of my systems.
I don't want to run the same OS on my phone, desktop, laptop and hypothetical tablet, set-top box and server. They each have distinct uses, and each require (or at least, would benefit from) a slightly different OS.
Hell, I don't even use just one desktop OS. I run Windows/OS X on my desktop - OS X is a good desktop Unix, but it's weak on gaming so I have a Windows disk as well. My laptop is currently Windows + a blank partition I haven't gotten around to slapping Linux on. Windows for light work and gaming, Linux for quick-boot, low-power stuff like media playing.
Now, what I would like is better cooperation between systems. Get read/write drivers for all the major file systems on all the major operating systems.
You could have them change off every so often, so none are in the lead for the full time. But that's really only if you're doing this to extend your range. If your concern is mainly decreasing costs, you would just fly them like this, but within the range of a solo aircraft. You would probably even fuel up each craft with enough fuel to handle it solo, just in case something happens.
No, that was the big genius idea behind Plan 9. UNIX saw that, took the ideas that worked (like procfs) and used them, but skipped the less useful ideas (doesn't Plan 9 have a pseudo-file for each window?).
The overarching idea behind UNIX is "whatever". Name any "big genius idea behind UNIX" and I'll point to a dozen counterexamples.

Do they have not just the official, but the unabridged ripped version of Legend of Zelda: Twilight Princess? Do they have all the FF Piano Collections?

Something tells me I'm just too much of a nerd for Pandora to have all the music I want.
Well, the article, hell even the summary, would seem to contradict you: "A single mysterious computer program that placed orders — and then subsequently canceled them"
I think you're talking about retroactively canceling them - reversing the order well after it occurs. This is more like rolling back a SQL transaction right before it would be committed. Or perhaps it's more like a SYN flood...
I've noticed this as well - my boss usually puts some Pandora station on the office sound system. It tends to play a very limited selection - we'll often hear the same song several times a day.
I don't use them mainly because I already have a 30GB collection of carefully organized music, mostly video game soundtracks that don't exactly show up on Pandora anyways, much less organized by originating console with playlists for similar in-game context.
Eh, it'll last at least as long as my lifetime, barring the sudden spike in longevity all the Singularity folk keep yammering on about. Which is effectively forever as far as I, personally, am concerned.

Are you sure about that?

It has to be the specific game - it goes by the Steam game ID, not by the executable name (which is hl2.exe for *most* Source games).
Nah, truly incredible programmers trap SIGKILL.
For "not being Bush", as far as I can tell.
I think you're either vastly over-estimating the value of a carwash, or vastly under-estimating the monthly cable bill.

Get a good city bike.

That was the commercial break.

Which makes it perfect for misdirection.

Pfffft, Myspace? That HTTP-using sellout?
Real hipsters switched back to personal gopher sites a while ago. Soooooo vintage.
Yes, but do they have ALL of it?
Do they have not just the official, but the unabridged ripped version of Legend of Zelda: Twilight Princess? Do they have all the FF Piano Collections?

I thought it used 2.5" hard drives. Or am I thinking of the Mini?
Indeed, this is a rare counter-example to Betteridge's Law of Headlines.
Man, we could really use a lowercase $ for posts like that...
