Studs are typically spaced 16" apart so you may find it convenient to get a level at least this length for when you need to span two studs for a shelf. Less commonly, studs can be spaced 24" apart, so you would be safest to get a 24" level.

There is only one of every species, by definition of species. You can have a number of varieties within one species, and Homo sapiens is no exception. We just don't call distinct human groups a "variety" even though there are obvious differences between sub-groups.

Soon, common knowledge will be entirely made up.

Duds are sold too, I'm sure. At work, we use Makitas with off-brand batteries; no problem with those.

I've just bought a couple of non-Milwaukee replacements for my 12v tools online. Cheaper, higher capacity, and they're working just fine so far. I can't speak for the 18v alternatives; maybe someone else has tried them.

Humanity may never become an interstellar species for an entirely different reason. Just as Homo sapiens barely existed 300,000 years ago, it may no longer exist in another 300,000 years by virtue of having evolved into another species, or even several other species. Some may evolve into a species better suited for space habitation: less reliance on skeletal structure, less oxygen needs, extreme longevity, perhaps resistance to the effects of cosmic radiation, things like that. These may reach other stars, and while they would no longer be considered human beings, they would owe their existence to their ancestors, of which you may be one.

Among billions and billions of planets, surely you can find a pair that are pretty similar to each other. Like rocks: they're all different until you look closely for a comparable pair. It's just a matter of deciding how similar they have to be before you declare them identical, and that's a personal decision.

I put everything in the dishwasher. I keep the survivors.

Like the Ship of Theseus, you can repair a shed forever: remove the rotten part, put in replacement part. You know it's time to replace it when you see that it needs repair but you're sick of patching it up, or you just want a serious quality improvement and have saved the money you need to get it.

If you don't think the current generation will see humans on Mars, you're in the minority.

Humanity today bears little resemblance to what it was 10,000 years ago.

> 500 generations

10,000 years? I think you err far to the pessimistic side.

Citric acid. It's the stuff they sell to clean coffee makers and similar appliances. It is also used in the food industry so you can sometimes (rarely) find the powder/crystals in the seasonings section at Walmart and elsewhere for cheaper than the coffee cleaning stuff. I always get a few pouches whenever I see it because it's not common but very useful for that purpose.

Throw a bucket of water directly in the toilet bowl so it will flush itself out and leave only a shallow water level, so less water in the bowl means more concentrated acid solution. Pour 2-3 table spoons of the stuff and leave it overnight. Next morning, use the toilet brush to finish off the job.

I'm sure there is also a maximum height so you can fit in. The workable range may have to do with the layout of the instrumentation, but I suspect it's more about the space suits. Those need a large number of life support systems that would each only come in one size, and all of them have to be part of the suit in some workable configuration. Then these suits with a person in them must fit the seats, which must fit the capsule.

Nowadays they announce those as they announce traffic accidents: "Collision on highway 1, please use alternate routes. Active shooter at the naval base, please avoid the area. Expect rain tomorrow, carry an umbrella."

Right. Someone else here mentioned it: locate a power outlet. The electrical box for them are nailed against a stud, which is either on the left or right side of the box, so you only need to try two positions with a nail to find a first stud. Then measure in 16" multiples to locate the rest.

You cannot assume there is a stud 16" from a corner. If the wall length is not an exact multiple of 16" then necessarily there will be a corner where the stud is at some other distance. But if you take a small nail and try at every inch then you will find a stud somewhere along that length. Then you can measure 16" from that one and expect to find the next one. That is, unless there is a door or a large window along the way, in which case distances may have had to be adjusted there as well.

It's a damn good thing too because there are eight billion of us and we only live two or three billion seconds.

Ah, then an equivalent verb is "optimize", which means to modify (a process) in order to achieve maximum efficiency. The existence of this verb eliminates the need to verbify "efficient" without loss of efficiency.

You can't verbify "efficient" because you can't efficient something without saying what you're doing, and what you're doing is the verb, not how you're doing it.

It's hard to attract the well-fed with food, so they attract the hungry who are typically in need of psychological support as well, and who are prone to listen to whatever they're told for a meal.

Don't trim it, move it out a little bit. If you trim it, you might chip the finish or end up with an uneven edge that will bug you for years. But if you pull out the dishwasher to see how the side panel is attached to the countertop then you may be able to unscrew a couple of brackets, move the top just 1/8" and screw it back. There's a good chance this will be enough and you won't have to also move the bottom. But if you need to, then pull out the quarter rounds, try to gently tap the bottom to move that out as well; it might just move enough to give you the clearance you need.

No, no, it's fine.

> Near-whole ankylosaur remains found

Just like it says, a near-whole ankylosaur was found, and as of today it remains found. ;)

I believe that mass is made of cheese.

Your turn.

I seem to recall they flew one of them, unmanned.
