It could be tidally locked to the sun too. Then days would truly cease to exist, you'd just have a hot side and a cold side.

To be clear, that's Cataclysm:Dark Days Ahead or CDDA. It's quite removed from the original cataclysm by whalesdev, and is more focused on strict realism. There is also Cataclysm Bright Nights which is closer to the arcadey feel of the original. Both are great and are open source.

Going to submit my probably-not-a-puzzle-game-game: rhythm games. The game tells you exactly what to press and when you're supposed to press it, it's just up to you to actually press the buttons. See: DDR, Rhythm Doctor.

Note that there are rhythm games that have more decision making like crypt of the necrodancer (rhythm roguelike)

Clickspring is currently recreating the antikythera mechanism using period accurate tools and technology, which is low tech if you consider that it was high tech for the ancient greeks.

The interest you earn is the bank paying you for borrowing your money. Conversely, the interest you pay for your home loan is you paying the bank for borrowing their* money. (*the bank's money is actually all the bank's client's money)

The interest the bank wants from you is almost always going to be much higher than the interest they give you for borrowing your money, as they want to make some money as well. Hence it's almost always more worth it to minimise the amount of money you lose to the bank's interest than you gain from your interest.

Hypothetically if you had 400k in savings at 3% and had a 400k loan from the bank at 6%, it's obvious that the interest you get from the bank will be less than the interest the bank is getting from you. But the trick here is that your 3% is less than that due to tax since it's money gained, but the 6% is the same since it's money owed. So it's more effective to avoid being charged interest from a tax point of view as well.

Not directly answering your question, but if you haven't already you should take a look at the end of life disaster recovery repo.

Yes, it really is that bad. We have a resin printer at work and it has been banished to a different room due to the resin fumes. The table it sits on is perpetually sticky, and we go through twice as much IPA postprocessing the prints than we use in resin

It already exists... sort of.

Cataclysm: Dark Days Ahead. Zombie survival roguelike, forked from the original cataclysm by whales. Also check out Cataclysm: Bright Nights which is a fork of CDDA that makes it more gamey like the original, and less like you're playing 2d arma.

Sunshine and moonlight are open source implementations of nvidia's game streaming protocol they created for the nvidia shield. You can use it to remotely use your computer from your phone, not just for games. But of course the primary application is game streaming. As long as the game can run on the host (sunshine) computer, you can remotely play it on the client (moonlight) device. I've used it to just launch steam in big picture mode and then select what I want from steam.

Powering the laser takes 300 MJ but the actual laser power (the energy in the light) is only 2.05 MJ. The rest of the energy is lost to heat and other inefficiencies. If the laser could be created with 100% efficiency then the input energy would also be 2.05 MJ.

You have to add them manually, either by url or with the built in search. For example, you can add newpipe by searching sources and checking github as a source to search. It will then show you repos that match newpipe, which usually is the regular newpipe repo and then a bunch of forks of it.

Obtainium isn't for finding FOSS apps, it's for installing them. To find them, you can check out existing repos such as f-droid or izzy, or you can ask around. This post has a bunch of recommendations in the replies

Obtainium lets you install FOSS programs directly from the developers source. You can get updates from the github/gitlab of app developers before they get uploaded to F-droid.

Lossless Cut FOSS, Crossplatform frontend for ffmpeg. Note that to do it losslessly, it will still be in mp3. If you need to transcode you can do that too, but like others have said you'll probably lose quality.

Nobody tell banks about fortnights

"Trust me."

I mean, you can grind your own mirrors, how hard could it be? (Spoiler: very hard)

Near the bolt holes joining the two halves, you can see thin strips going across that overhang gap. Those eliminate local sagging without needing support material. The part could have been flipped 180 instead, but then the outer edge rim would be unsupported.

Those deep holes in plastic parts are always the worst. If you have a dremel you have 2 options. Either cut away enough of the top plastic that you can get at the screw to dremel a slot into the top, and unscrew it with a flathead screwdriver. Alternatively you could try dremel just below the head of the screw to cut the screw in half.

if you have a soldering iron you could also try heating the screw to melt the boss it's screwed into. You might have to cut/melt away plastic to access the screw and then apply light rension while heating so that it opens once the screw is hot enough.
