That's what someone recently said on a forum about Pi. Simple: you use as many decimal places as you need. In the case of Pi, 39 decimal places will measure the circumference of the visible universe to within the diameter of 1 hydrogen atom. So, for most projects, somewhat fewer than 39 decimal places should suffice.
I've done a lot of measurements for building and drawing things in my time, and most often I need fine measurements. mm and ml are better because they are small whole units. It is easier to define something as, say (n)mm, than use n/32" or n/64" as a unit.
If you are cutting a metre of wood into thirds, you only need as many decimal places as would take you to the width of the saw cut (not as many as you might think).

The REAL WTF is the fact that the poster did not find the bug during testing and closed the issue as 'could not reproduce" LAZY LAZY LAZY and gives IT a really bad rap with users.
Admin
Which is a perfect demonstration of why such measures are beyond useless, given a) walking speeds vary hugely between different people, and b) how accurately are you measuring your 20 minutes?
Admin
If you are going to go all the way with metric, shouldn't you demand a clock delimited by kilo-seconds?
Admin
Yes, there is. But this conversion was from a string representation, which one should really avoid doing in PHP.
Admin
The standard measures are in the binary system. A cup is 2^3 ounces, a pint is 2^4 ounces, a quart is 2^5 ounces, and a gallon is 2^7 ounces.
The Babylonians originated the base-12 time of day system, because they had 6 fingers on each hand.
Admin
Properly speaking, 12 noon is 12 M.
Admin
TRWTF is metric time.

http://www.google.ca/search?hl=en&q=50%20cups%20in%20gallons gives the same result as http://www.google.com/search?hl=en&q=50%20cups%20in%20gallons
Fortunately it says US cups and US gallons, so we know Google Canada is doing it wrong.
Even more fortunately, there are dropdowns to correct ... half of it. Google Canada lets us select imperial gallons but not imperial cups.
An imperial cup contains 8 imperial ounces. There are 2.5 cups in a pint. There are 160 ounces in a gallon.
A Japanese cup is 200ml. A Japanese gallon doesn't exist. I wonder what Google Japan's syntax is for unit conversions.

In the US you don't even get 1 ounce of water = 1 ounce of water, when you measure it and weigh it.

And if it's what you meant, you were wrong. If you cool your cloud of steam to 37degC (human body temperature), just under 1psi of it will remain in vapour form. (This is the pressure at the Armstrong limit, around 63000 feet altitude. If you get higher than that, unprotected human life is impossible because exposed bodily fluids (saliva, the water on the surface of your eyes, etc.) boil away. Of course, low pressure kills people below that altitude even with pure oxygen to breathe, but at/below 1/16 of an atmosphere, you die even quicker.)

If I say that the schoolyard ends at the wall of that adjoining building, do you than truly think that that wall is part of the schoolyard to, and you should be able to place yourself where that wall is ? If so, you can get a darwin-award at my place. :-)
If not, why do you guys think that when the day ends at 24:00.00 hours that that second is also part of that day ?
What if I remove the minutes and seconds from it -- the day starts at 00 hours and ends at 24 hours -- is than suddenly the whole first hour of the next day part of the current one ? Really ?
Also, when you say that a day starts at 00:00.00 hours and ends at 24:00.00 hours inclusive you would have a second overlap (24:00.00 equals 00:00.00). Or the day would need not start at 00:00.00, but at 00:00.01, which is not quite logical ...
Admin
We use decimal because it allows us to write using only 10 symbols. If you had to use a sexagesimal counting system, you would need 60 different symbols (complicated leraning when your alphabet has twentysomething to thirty something glyohs) or use compound symbols, which is a mess like the roman numerals.
So we use decimal system just because of historical convenience (and also maybe because we have 10 fingers).

Oh... I'm so glad that the Imperial system is precise to the femtometre when divided, unlike that pesky metric system. I mean, it's easy to see how 1/3 of a mile is so much more precise than 1/3 of a km, or 1/3 of a foot doesn't need any approximation when measuring it, which isn't the case for 1/3 of a metre, right?

If by "use repeating them" you mean "likelihood that people on one side will convince people on the other side to change their minds", well then of course the conversation is no use. Who said it was? The purpose of such conversations is not to change minds, it's the sheer entertainment value of the argument.
I suppose next you'll say that listening to great music has no purpose because it doesn't increase the output of steel mills.
Sheesh! What a pragmatist!

Back in the day, bus, train, & airplane schedules were printed in lightface for A.M. and boldface for P.M.
Noon being neither, that's why there were so many arrivals at 11:59 (lightface) and so many departures at 12:01 (boldface).
Admin
Admin
Oh nice, so time goes backwards from 12:00AM after noon.
Admin
All these comments and yet, nobody has remarked that 11/24 of the conditions would have been incorrect. (That equates to 5 1/2 in/ft or 45.3̅3 cM/M for standard and metric comparison.) For all the extensive replication attempt, it would appear a random sampling of no more than 2 records had been performed before closing as unable to replicate.
TRWTF is treating a commercial program like an open source bugzilla.
Admin
Our measuring cups mark the thirds and quarters, but no recipe ever asks for 1/12 cup; it would be "4 teaspoons" instead.
Admin
even better is the DateTime::createFromFormat function, since given the name of the user's function (getTimeFromISODateTime), the format of the incoming datetime appears to be known.

You can bake bread in a Dutch oven, but it doesn't turn out great. Best is in a campfire, where you can put hot coals on the lid and approximate an oven. If you get the pot hot first the contained steam will make a nicer crust.
Interesting (to me) the use of the word Dutch here comes from the Anglo-English wars of the 17th century, when "Dutch" was used to deprecate many things, so a Dutch oven is a poor oven. My favorite: "Dutch treat" for not paying for your own meal.
Admin
A cup doesn't happen to mean whatever cup you have lying around, any more than a foot is the length of YOUR foot. A cup is 250ml.
Admin
What cretin came up with that system? I still see flights with departure times of 00:01, perhaps to avoid date ambiguity?
Admin
Some Guy I know sometimes suggests meeting at (e.g.) 12:75 when he means 13:15. And I saw actual digital clocks which displayed 23:59--24:00--24:01 ... and at some point switched to 0:0x. It looks very buggy, but there is actually no ambiguity there.

But then something similar to bread, pizza bases, do need precision. Even 100mL of water makes a difference in a ~16kg batch. But then the temperature of the water and ambient temperature makes a difference too.
I used to make pizza bases by the hundreds when I worked in a certain chain pizza shop during my uni years.

... which proves that (a) Lamarck was right about inheritance of acquired characteristics, (b) modern man descends from Swedish sawmill operators, and (c) human beings are intrinsically ambidextrous.
Admin
Now I really want to know what it means elsewhere.
Here it means a large, deep cast iron pot, usually enameled, with a heavy and close-fitting lid. (which makes a great environment for baking, since the cast iron radiates heat evenly from all sides, and the heavy lid retains the moisture from the dough, producing a glorious crust)
Admin
So any time after 13:00:00 & before 00:00:00 would be wrong. Maybe he tested it out of this time range. Still very bad. tch tch tch

A friend from the UK told me once, that a "dutch oven" means: "Trapping" another person under a blanket (so that his/her head is covered) and than farting under said blanket.
Admin
Wow, thank you for sharing that. This knowledge has truly enriched my life.

So this guy invented the boustrophedon approach to daytime. I just wonder why the US doesn't use this system, as they clearly are optimizing their time- and date-keeping for WTFiness.

It's not a decimal system so OF COURSE nobody remembers the decimal value. And yes, it's stupid, and I agree that we should just go metric already...but there IS certainly logic to it. If I give you a liter bottle of water and ask you to fill it to the next smallest unit -- 1/10th of the bottle -- how accurate do you think that would be? It's hard to mentally divide something into ten. Imperial units are largely based on halves and thirds, which are much easier. Give me a bottle and I can fill it pretty close to halfway just by looking at it. Even a quarter. Two cups in a pint, two pints in a quart, and as the name implies, four quarts in a gallom. Nobody would EVER use 0.0625...we'd use 1/16, because they're fractional units. Which works pretty well for common usage, since it's much more likely you'll be halving or doubling a recipe than multiplying it by ten (note how I don't even know the word for 'multiply by ten', assuming we even have one, because it's so infrequently used.)
Metric units are designed for science; Imperial units are designed for people.
Admin
No, the NEWTON is a unit of weight. Kilograms measure mass.
Admin
Bingo.
And since they're freely convertible, it doesn't matter.
For those that get really worked up about it, I'm working on an app for the google goggles that'll replace Imperial measures with metric in anything you happen to be looking at. The working title is the "Pretentious Fuckwad Eyeball Protection Scheme" but I'm open to other suggestions.
