 Wait, so your argument is that because you don't need to know precise numbers, that the Fahrenheit system is better for day to day use? Following that logic, wouldn't the best system for day to day use be "Hot, Cold" and some modifiers such as "Really" and "Extremely"? Do you know what else comes really close to capturing the temperatures we experience? Literally any scale that can be used to measure it.

Neither system is really convenient, when you come right down to it (though I like the idea behind the quote above about 0 F being too cold and 100 F too hot) I vote for a system where 00 is freezing and 10 is boiling, and room temperature is around 00.0111. Don't we all agree that would be much more convenient?

 Supposedly a design goal of the Fahrenheit was that temperatures below 0 would be unusual (avoiding those "tricky" negative numbers), and that for "usual" temperatures you wouldn't need to use decimals to get enough precision. Hence 0-100 represent roughly the range of temperatures you get in Europe. The precise values were chosen so that the resulting thermometers would be easy to make and calibrate; 0 and 32 are easy to get reference points for, and making 32 even divisions is easy to do. Celsius isn't really a sensible unit; for real scientific work you'd want degrees Kelvin, and for everyday use it requires you to use fractional degrees.

 operagost:First of all, you don't turn up the heat on a hot-water system by directly manipulating the radiator.Um, in my first long-term apartment, you did. That was our control over our heat. Ben:Wait, so your argument is that because you don't need to know precise numbers, that the Fahrenheit system is better for day to day use? Following that logic, wouldn't the best system for day to day use be "Hot, Cold" and some modifiers such as "Really" and "Extremely"? Um, that wasn't my argument at all. My argument was that the specific numbers the Celsius scale is anchored at -- the melting and boiling point of water -- are not important. Using "very hot" is a problem because it would either not be an absolute scale ("very hot" to me is quite different from "very hot" to someone who lives in Florida) or it would overload the terms like "hot" (more and in more confusing ways than they already are). Do you know what else comes really close to capturing the temperatures we experience? Literally any scale that can be used to measure it.Coyne's response is best. 0-100 is more convenient than -15 to 40 for similar reasons to why "0.011 is room temperature" is less convenient. jt:Celsius isn't really a sensible unit; for real scientific work you'd want degrees Kelvin, and for everyday use it requires you to use fractional degrees. Eh, I disagree on that last one. 1 deg C is about 2 deg F.

Remember that Celsius used to be called centigrade. Freezing is still 0. Boiling is 10 instead of 100. Room temperature in our kitchen when Vista died is 0.0111 instead of 0.111. It works. (We kept Vista in a bowl on the kitchen table. Vista came from the tropics and failed to adjust to Japanese winters. Vista got her name because I was installing another betta in a PC when we got her.)

 operagost:Second, your system will crash way before it hits 230 degrees F. I don't know of any CPUs that will survive exceeding the boiling point of water. My PC started having trouble booting up a month or two back. I went into the BIOS setup to check the CPU temperature (yes, TRWTF is that that's the only place I can see it) and found it was 104 degrees C. Vacuumed all the dust off the CPU fan and elsewhere, rebooted and watched the CPU temperature drop to 35 degrees C. No problems since. F***-it Fred:And then the poor bastard discovered that his overheated CPU had calculated everything wrong and rendered all that work useless. I thought something similar to this also. But really there are two options: (i) He realises that the previous results were likely to be affected by the CPU overheating and recalculates them later in the week. Noboy actually needed the data before then anyway and all is well. (ii) It doesn't occur to him that the calculations should be redone. Everyone accepts the results because they don't know what they were supposed to be (that's why they wanted to do the calculations). The resulting errors eventually show up as limitations of certain medical techniques, but nobody ever realises where the problem really lies.

I don't know if that was bad measurement initially or with copying the work later. 0 degrees was supposed to be as cold as it ever got - determined by sending a ship as far north from England as it could get and returning with the resulting measurement. So 32 is an accident, as is the size of the steps. Let me go check Wikipedia to see which of us is correct. If it is you, I will change the article. Wither way, I will continue on my merry way knowing that people who check it out after I do will agree with me.

You sort of do; at least here (UK) radiators have a valve on them which lets you control the flow of hot water to them. The actual temperature of the water is controlled by the boiler, of course.

 WhiskeyJack:I've had similar experiences at work, as have probably most people. One time I was working on a new feature just before Canada Day (think Fourth of July, you Americans). And just before I was going on vacation. I was told that my boss wanted to demo this the week after to a potential customer in Japan, and it had to be done. Period. OK, so I put in all kinds of overtime that week, including working the whole day on Canada Day. Delayed my vacation by a day too. Got it done. Sent off the code along with instructions on how to install and run it on the laptop they were taking with them to Japan. Then took off for a well-deserved rest. When I got back, I asked how the demo went, and if the customer was impressed with the new feature. "Oh, that? We didn't have time to show them." And you said, "I worked overtime, delayed my vacation and worked my ass off to get it done, why didn't you do your part, asshole?", right?

Promise you'll deliver 7 hours early and you're just stressing yourself for no good reason. Second, the correct response is "The research notes are due tonight? Wow, that sucks for you. You'll have to tell me how it went when I feel better."

Think: light is sometimes written as lite (see e.g. non-British European cans of Diet Coke, called Coca-Cola Lite), so lighter should be writeable as liter. Alternatively, a liter is an American litre. The American cubic centimeter is about 5% larger than the European cubic centimetre, but they have 20% less of them in a liter than we do of ours in a litre, so the litre is 21% bigger than the liter. I should probably stop now...

The Fahrenheit scale is the product of the possibly-fevered imagination of Daniel Gabriel Fahrenheit, with some refinements later on to make it easier to use. DGF based the scale on a particular sort of "brine" (actually based on ammonium chloride, not sodium chloride) that melts at about what is now called 0 °F; normal water, which melts at what he pinned as 32 °F; and "blood heat" (body temperature) at 96 °F. The scale was later tweaked so that water boils (at pressures of 100 kilopascals) at 212 °F, which is why normal body temperature is just over 98 °F on the modern scale.

 B00nbuster:TRWTF is that he didn't immediatelly recognize that the crash was due to overheating. If my PC keeps crashing (and it must have rebooted, because that's the symptom of overheating!) under CPU load this would be my first suspect! I have yet to see a JVM that causes a rebooting crash. Bluescreen at most. But a rebooting crash??! TRWTF is that the poor ill guy was just inexperienced. Pretty sure that modern versions of Windows do not, by default, ever give a BSOD -- they just reboot (I know this is true of XP, though they may have gone back since.) So unless he'd gone digging through the system settings to change that, it's likely the two would have been indistinguishable.

Some cooling systems put heat sinks in water instead of air but the CPU doesn't know that. Most cooling systems use air. The CPU works fine when hotter than the boiling points of nitrogen, oxygen, etc. It's not that there was water to be boiled, but every PC I've used either malfunctioned or, if equipped, automatically shut down at temps between 70 and 80 degrees C, which is about 176 F. The "boiling water" reference is mostly for impact. What I HAVE found is improperly calibrated motherboard sensors that read as much as 30 degrees off (Celsius), which could have been the problem.

 danixdefcon5: jay: It must be very confusing living in Europe. If you want to get a feel for even a simple thing like whether your car gets good fuel economy, you have to convert liters to gallons, then you have to convert kilometers to miles, and finally you have to convert Euros to real money. :-)hehehe. Its actually easier to deal with ºC and kms, especially as you don't need to memorize uneven multipliers. Everything's metric! On the serious side: When I was in high school and college and was studying physics and chemistry, the advantages of metric were obvious, and I couldn't comprehend why the U.S. didn't make the switch. But when I graduated and became an IT geek, I didn't have much need to do a lot of arithmetic with units of measurement, and it just didn't matter to me any more. When I look up how far it is to my friend's house, whether I get that number in miles or kilometers doesn't matter much. Given that, I can see how switching from units that you are familiar with for no clear advantage just seems like too much trouble for most people. The biggest hassle I run into with English measurements these days is when I'm trying to follow the instructions on the back of a box of food. How many tablespoons in a cup again? Etc.

That's what made me wonder when exactly this alleged story could have happened. Andrew runs the software on his "desktop PC" at home. The last "desktop PC" processor that didn't have thermal protection of any sort was the Athlon K7 (the XP already had a sensor, but could still be fried if the board didn't properly support it). All later ones indeed shut down when overheating, most even throttle themselves to run cooler and avoid the hard shut down if possible. The actual temperature is CPU and sometimes BIOS dependent, but yes - 110C is beyond the usual. And most of the time the system works fine until it has to shutdown (a bit slower perhaps). But if there's misbehaviour, it's usually totally obvious - random processes terminating with privilege violations. The real WTF would indeed be not noticing that.
