“Sporange” does. If you’re especially bad at pronouncing words, many other things also rhyme with orange, like flange, range, and monkey.
- Comment on Your reflection has never blinked at the same time as you. 5 days ago:
The moon is about 1.25 light seconds away from Earth. There are retroreflectors placed on the surface of the moon by NASA, some of which are still functioning.
Given the number of people that stare up at the moon, it seems likely that someone has blinked twice with correct timing to be at the same time as their reflection.
On the other hand, I have blinked with my face only a few cm away from a mirror, so my reflection blinked 0.00000000007 seconds after me, so maybe “at the same time” is doing the heavy lifting here in the sense that there is some minimal period of time between most events we would consider simultaneous.
- Comment on I hate it when people use pictures showing the condiments only on top of a hot dog. 1 week ago:
People with big mouths (like me, I have a big mouth) eat hotdogs in bites that span left to right, and top to bottom along (approximately) a plane that lies perpendicular to the axis along which the hotdog was extruded. With this approach, the condiments merely have to run the length of the hotdog (or just the bun if you dislike messy eating) in order for them to participate in every bite.
Only small mouth dweebs that can’t fit a wide, juicy frank into their mouth when they’re gobbling down a… Nevermind, I think I got sidetracked.

Slander is spoken, and libel is written, so this would be libel if it is either. “There’s libel in the library.”
- Comment on Can someone fact check this 1 month ago:
Owls don’t weigh 16 pounds (except for fat owls). 300 kilowatts is a rate of energy, not a total quantity of energy. 300 kilowatt hours (which is possibly what they meant?) Is only around 260,000 kilocalories (which is called “calories” on food labels because units of measure were made up by humans). According to an extremely naive google search, that would only take an owl 5 years to consume, rather than 10. If the original number were correct, that would mean this owl eats 8,000 calories per day. Which is not typical.
Onto the broader point, the efficiency of birds in flight is not as simple as this image suggests. There is no (useful) formula that takes the weight of a bird and the distance it will fly and tells you how many calories that takes. Birds can fly at different elevations, at different speeds. They can fly with or against the wind. They can change many things about how they fly to be more efficient or less efficient.
If you really want to know how many calories it takes for an owl to cross the ocean, first get the owl to the point of starvation, then bring it on a boat to the middle of the ocean. Feed it a fixed number of Tootsie pops, then sink the boat. With nowhere else to land, the owl will be forced to fly to shore. Based on how far the owl makes it, you can determine how far each tootsie pop allowed it to fly, and derive calories per mile from that.

They would hit the mountains at that height, and the FAA requires them to be up above airplane traffic anyways. After that, it gets crowded right above the launch pads, and sometimes there’s shooting stars and stuff, so some satellites are forced to go even higher.
- Comment on IT'S A TRAP 1 month ago:
Two sets with infinitely many things are the same size when you can describe a one to one mapping from one set to the other.
For example, the counting numbers are the same size as the counting numbers except for 7. To go from the former set to the latter set, we can map 1-6 to themselves, and then for every counting number 7 or larger, add one. To reverse, just do the opposite.
Likewise, we can map the counting numbers to only the even counting numbers by doubling the value or each one as our mapping. There is a first even number, and a 73rd even number, and a 123,456,789,012th even number.
By contrast, imagine I claim to have a map from the counting numbers to all the real numbers between 0 and 1 (including 0 but not 1). You can find a number that isn’t in my mapping. Line all the numbers in my mapping up in the order they map from the counting numbers, so there’s a first real number, a second, a third, and so on. To find a number that doesn’t appear in my mapping anywhere, take the first digit to the right of the decimal from the first number, the second digit from the second number, the third digit from the third number, and so on. Once you have assembled this new (infinitely long) number, change every single digit to something different. You could add 1 to each digit, or change them at random, or anything else.
This new number can’t be the first number in my mapping because the first digit won’t match anymore. Nor can it be the second number, because the second digit doesn’t match the second number. It can’t be the third or the fourth, or any of them, because it is always different somewhere. You may also notice that this isn’t just one number you’ve constructed that isn’t anywhere in the mapping - in fact it’s a whole infinite family of numbers that are still missing, no matter what order I put any of the numbers in, and no matter how clever my mapping seems.
The set of real numbers between 0 and 1 truly is bigger than the set of counting numbers, and it isn’t close, despite both being infinitely large.
- Comment on Is anyone NOT steaming their Music? 1 month ago:
I’ve been buying and ripping CDs since 2007. I average 8 per year, and it limits my music discovery speed a fair bit - but that’s OK.
When someone suggests a new song/band, I listen on YouTube/Vevo, and put up with the ad. It’s fine. It convinces me whether I want to buy their CD or not most of the time.
- Comment on Everyone thinks the Deus Ex remaster looks awful and they're right: 'They really turned those 1999 graphics into 2003 graphics' 1 month ago:
“AAA” gaming began as a reference to the “AAA” creditworthiness rating, meaning (essentially) “certain to repay the loan” // “certain to earn more than the development costs” (contrarespectively). AAA gaming has always been about the safe bet, the easy money, and the tailored to mass market design.
High budget games can only have so much ROI, so there’s kind of implicitly a limit on how much risk is tolerable for investors/publishers. Meanwhile, a game that costs a few million (or even less) could be the next big success, and rake in a massive sum - enough to justify its own budget in addition to many failed attempts to craft a star.
Even more risky is indie gaming, where the cost of development is provided by crazy people that want to produce “fun”, and gain money as some kind of (important) side effect. That’s where you get the wild “no one (in the know) would expect this to work” ideas, and most of them do fail, just as expected. The ones that are good enough to make it are by nature surprisingly good - indeed, this surprise is why publishers won’t go after the same concept under most conditions.

It’s not just about slavery. There was also state’s rights (to slavery), and the economic disparity (turns out free men work harder than slaves?!), and a clash of religious ideals (people that interpret the Bible as pro-slavery vs people that believe benevolence requires abolition). There were even one or two spots where water usage rights and federal funding were in controversy.

- Comment on '3d-printing a screw' is a way to describe how AI integration is stupid most of the time 2 months ago:
A 1.5" long number 8 wood screw has slightly more than half the holding strength when it is driven by a hammer into 2 3/4" pine boards, relative to the traditional rotating the workpiece approach, but takes only about 1% of the time to install. You can very easily add a second screw to achieve the desired strength, while often gaining resistance to torque in the workpiece.
Meanwhile, 3D printed screws usually break when struck with a hammer, so they’re no good for this approach.

- Comment on Is it wrong that i would like to start a small 3d print business? 3 months ago:
I’m not in this business, but I have purchased prints from a print farm before. There are already at least 4 large, high quality printing companies that offer to print any model in any material. I think most of the competition is now on speed and price. There are also many smaller printers I have purchased from. Most offer ~10 products, have them already printed, and sell those items to fulfill a specific need. As far as I can tell, those smaller printers either design their own models, or paid for models that are not readily available. Once model files are available, the general purpose printing companies can deliver the same part.
Unless you have ideas for models no one has made before, and you want to try to profit as much as possible off those, I don’t see the upside to a small print farm.

I was going to take it in a 1987 Toyota Camry, manual transmission, but the clutch burned up (not my fault… Maybe), and my parents didn’t want to get it fixed. I took the test in the driving school’s only manual transmission car, which was… A gray sedan, with a second brake pedal for the passenger.

You do not need to objectively benefit from a positive outcome in order to enjoy it. My local sports team wins at least once per blue moon, and I feel good despite neither profiting from, nor contributing to their successes.
I can understand if it doesn’t do it for you, but I’ve found a great deal of joy in things that do not materially benefit me. I like it better that way.

The text on a Twix wrapper runs in the same direction as the Twix inside, so it’s better to say they’re top and bottom Twix - otherwise it’s ambiguous based on the direction of the packaging.

I’m bragging when I say this: A decade ago, I rewrote an indecipherable mess of code into an elegant and transparent procedure, nestled comfortably inside every sanity/insanity check I could think of for the situation. Today, that code (aside from an update for a vulnerable dependency) is still running just the way I wrote it.
Releases should be fast and rare.
