How would you do either of those activities with Linux. I know you can cat stuff into the cache, and you can control the "swappiness" and something about dirty inodes in proc/sys, but how could you say "I want this file to be in the cache no matter what" or "what files are in the cache" other than by creating a ram disk and putting them there (and then wondering why your ramdisk files are also cached because you used/dev/ram instead of tmpfs...) manually?
It's always easier to do at low speeds because F_drag = c*A*v^2 Cut the speed in half, and you cut the {work/mile} by three quarters. Of course, at some point you have to start cutting switchbacks and tunnels everywhere because your (properly sized for the desired speed) power plant can't climb moderate inclines, but you'd be really efficient!
Of course, it's a lot easier to pull out in front of a truck when you're sitting in a recumbent position with your eyes no more than two and a half feet off the road.
Which brings me to a pet peeve of mine: poorly thought out landscaping on street-corner properties. I know you think your ugly bush looks cool and all, and the tree next to it really hides the street sign you placed them around, but street signs are there for a reason, and blocking drivers' view of oncoming traffic is just plain mean. Stop doing it.
That workaround was good, but not nearly enough better than just setting the max and min size of the swap file to the same number and defragging to justify repartitioning. And if you had enough memory, it was still better to just turn it off entirely.
In many respects FDR was our worst president. I know that's an unpopular view, nevertheless that's what I think.
Of course it's an unpopular view. Woodrow Wilson was just as racist and far more damaging a president that FDR ever was. FDR only screwed up our country. Wilson sowed the seeds of WWII (increasing our enemies by one Japan in the process), the war in Indochina, screwed up domestic race relations, created the Federal Reserve...
You should be alright as long as you play some movies on the phone before putting it in your pocket, and play movies on the phone while it's in your pocket before going inside.
The problem is when the partial pressure of H2O exceeds the dew point. If you raise the temperature by moving into a new volume of air, then you get the ppH2O of the new volume of air, which is instantly cooled to near the temperature of the device, possibly crossing the dew point and causing condensation. If you raise the temperature of the existing air within the device through, say, its own heating, by taxing the processor, then the ppH2O will not change, and in fact will move even further from the dew point (since the max ppH2O is higher with higher temperature)
If you're unwilling to preheat your phone every time you move from a cold environment to a warm environment, the I suggest that you simply don't have the dedication required to operate a fine piece of apple electronics. Your expectation that a $2k device intended for everyday use should be more robust to common, everyday activities is unfounded and unreasonable.
People keep talking about the price of print and the revenue from advertisers, but no one mentions one very relevant number: the per-person ad revenue.
If you know the per-person ad revenue, then you can easily calculate the break-even price at which the print version and a theoretical ad-free online version would have no loss in revenue, presuming zero net change in customer base.
So, their total revenue in 2008 was about $3 billion according to google finance, and they sell an average of about 1.2 million papers a day according to one of the investor reports, so they're making no more than ~$7 per copy. (since total revenue on their stock page may include things other than "ad and subscription revenue") I don't know how to break that down any further, though because the info I was able to obtain did not include any data about the price people were actually paying for subscriptions.
Still, that comes out to a lot more than $30 per month, which surprised me quite a bit.
I wish there was a tool that could tell you how many cycles are wasted waiting for stuff that's not in each of those caches, so you'd know what to try to upgrade next. No point in throwing more RAM in if the bottleneck is insufficient L3 cache...
However it was my experience with windows up to XP that turning off swap does unfortunately result in a performance improvement. My suspicion was that it was preferring to put things in there that are actually in use in favor of caching stuff from the disk that more rarely gets used, and possibly doing it at inopportune times.

20 Years of Photoshop
·
· Score: 1
The title was "you suck at photoshop" but I gotta say that I think they did a terrific job there hiding the truck with the dud missile. No trace of the original truck was visible, and they faded the trail and whatnot so that unless you were looking at the shape of the billowy dust cloud, you could easily have taken it to be a picture of four successful launches instead of the 75% (or less. we wouldn't be able to tell if it was cropped) of four launches.
They're certainly much better photoshop artists than whoever reuters got workin' for them.
I always figured the problem was that by the time you work your way through the business until you've got the veto power of being the head sound engineer, your hearing has degraded to the point that you really don't know what you're doing. Through a combination of age and too many hollywood cocktail parties, you can't hear the music OR the dialogue very well, but can feel the vibrations (like a snake) if you push the music up high enough.
I find it hard to believe that the CO2 equilibrium would just happen to also be the maximum. You're suggesting that the tolerance on that equilibrium is less than 5%!
If you were analyzing any other system with feedback, you probably wouldn't even bother ditching a linear model over a 10% perturbation, yet you're claiming that the Biosphere has such stringent tolerances that a 5% perturbation of annual input of a trace gas is catastrophic?
Very well. What is a reasonable tolerance, then? If you say zero, then we might as well all kill ourselves, we can't live on zero unless we want to be hunter-gatherers with child mortality rates of over fifty percent and a good chance of never seeing our thirtieth birthdays.
Fuel dependency is an issue though. The US has tremendous coal reserves. In fact, we're known for having one of the cleanest patches of coal on the planet (but that's a national park now, so we can't burn it....)
What we do not have is tremendous uranium and thorium reserves. So, in nuclear-powered world, we'll be depending on "foreign atoms" many of which will be dug up in Australia.
Err. I think you're thinking of the movie "The China Syndrome" which apparently was believed like a documentary.
Also Carter and his quest for no more nuclear weapons shut us out of like 98% of the capture-able energy through ill-founded treaties. So of course it makes it look like waste storage is a big problem.
In this particular incidence, the 30 years experience is what's holding you back. A newbie would've read the manual* and done the tutorial and found the list of keyboard modifiers.
*although.. the manuals and tutorials seem to be getting thinner all the time...
But, more to the point, the state of buttons that are off the screen is indeterminate. It is unwise to use any shortcut to press them in that state, although in your specific example the defaults appear to be well-chosen in two Oses. The correct behavior is not to put the buttons off the screen, but failing that (and there will always be some software that fails that, but hopefully at least not the system settings dialogs), there needs to be a way to move the window around so you can see an manipulate all the relevant controls. Especially for a dialog that changes system settings.
Windows at least used to have this functionality, IIRC, though I haven't checked recently. Not as convenient as alt+move, though. It was more like alt+space(or was that minus) (m)ove then the mouse turns into move arrows and you can move the window by dragging. I'm not sure if it worked on dialogs, though.
Anyway, linux is the one with the correct fall-back behavior here. In either case, you rely on arcane knowledge to get you out of the predicament of improperly set display size without rebooting, but linux's arcane knowledge is the fact that you can move the window to expose the controls, while OS X's arcane knowledge is the idea that you won't screw up the system by blindly hitting enter.
why doesn't the desktop properties window fit (thereby leaving me stuck?
you're not stuck, although that does sound like bad design. Fortunately, Gnome has a solution to the general problem of poorly sized dialog boxes going off the screen for whatever reason. Hold the [alt] key and click anywhere in the window and drag. Which is a far sight better than what Apple has chosen to do with windows that go off screen: Resize automatically sometimes, only allow moving windows from the thin strip at the top, and only allow resizing windows with a small tab on a single corner.
I heard they were making a big switch to mud brown in the next edition. As for looking like a desert wasteland, it also looks like the inside of every trendy coffee shop and Panera Bread, so you know a lot of thought went into its innovation. In fact, that's the very measure of original-ness: is it found in thousands of trendy stores nationwide? Then it's originique!
Product prices will be the highest the market can bear
That's really only part of the story, though. It depends in part on the elasticity of demand and supply.
In say, the oil industry, where margins are already razor thin (7% last time I saw it mentioned), and where demand is fairly inelastic and slow to respond (I need to commute to work, I rather like having produce and finished goods to consume and improve my life with, etc, and I don't see trucker's all switching to some other fuel overnight), the customers could very well see any fees or taxes passed on pretty directly.
In the software industry, where the marginal cost of a cardboard box with enough polycarbonate in it to make half a pair of sun glasses is very low, and the product itself isn't consumed and doesn't really even degrade ("I could make due with this older version for a few more months"), You might see extra burdens simply being absorbed.
But in the latter case, it's not the executives who feel that pinch, but the investors. And who are the investors? In a publicly traded company, it's odds on that a significant fraction are "institutiona.l" i.e. retirement funds. e.g. your retirement fund.
What's wrong with secretarial and janitorial work, btw? It's menial and boring, but nevertheless necessary to a well-functioning company, and provides jobs that require little training. Furthermore, a company has to be headquartered somewhere, and will therefore need secretaries there. Why not "here?"
But you're right that we want more than just the corporate headquarters. We want the facilities as well. And one of the reasons we want them here is so that they'll be subject to our laws. If we've got restrictive laws and high taxes, they're just going to go somewhere else that has neither and put kids to work in the mines or something.
You make a good point. Although one might argue that standardizing on a format with five years of patent risk some years down the line is an improvement over "using that same format, but also wrapping it in another even more proprietary format."

Hmm. What do you hit to set the opacity to 5%?
