You joke but one of the biggest problems of actually delivering aid to the hands of the people who go hungry is that along the way it passes through the hands of a local warlord and magically turns into AK-47s. Trying to skip the warlord also has drawbacks, in the form of said AK-47s being used to convince aid workers to hand over the rest of the goods. It mostly boils down to a catch 22 of "effective delivery of aid needs a stable and competent government to support it" and "people mostly experience famines because they don't have a stable and competent government".

Planets are hard to miss and they do not take unexpected turns like some drunk git on a highway. If you know where Mars is now and its velocity, you can predict where it'll be in exactly a thousand years, probably down to a few tens of meters of accuracy.

> why can't do the same with wall plugs.

There is absolutely no scenario when a properly used wall plug is exposed when energized. Is is only possible when utter morons use "suicide cords":

  • for extensible christmas lights they installed backwards so the socket end is near their wall socket. In that case, the user needs to suck it up and take it down then put it up the right way. It's an educational experience.

  • for plugging in generators to a wall socket when the power goes out. This is illegal as fuck and dangerous to linemen working on the pole outside. An excellent way to bumble your way into manslaughter. When generators are used for a home, a generator inlet socket and transfer switch is used The house side is male with exposed pins, but due to the transfer switch it is physically impossible to have it connected to the house wiring while the house is fed from the mains, so it is safe.

> a plastic board covered in fibreglass

The board is the fiberglass+resin. Usually. That is called FR-4. Sometimes you see ultra cheap boards that use paper and resin (FR-2) substrate. On top of that is one or two layers of copper foil, glued down, then after etching the traces it is coated with UV setting liquid plastic called solder resist.

OLED also incurs extra power cost when switching stuff around faster (at the minimum, there are a bunch of multiplexers and a logic driver to convert from the display input signal - a serial protocol over a couple wires - to the thousands of pixel row/column lines) but power save mode on it is usually switching to a dark color theme which lets it turn off pixels and reducing overall brightness.

  1. Lower power consumption from the CPU and GPU as they don't need to prepare and render that many frames

  2. Lower power consumption from the LCD panel - it takes power to flip the little crystals from transparent to opaque, and generally the faster you want something to work, the more power you need to pump in it, though I think that last part is only relevant if the screen also switches to a slower response time.

Stretched out, your intestines are about 3 times as long as you are tall. Even if you have the runs, it works well enough to digest food most of the way - at least it shouldn't be just chewed sandwich coming out, if it is, you might wanna hop over to the ER yesterday -, which includes reclaiming the acid.

You can stick caltrops in dung so they are more dangerous than "3cm nail in the foot" would ordinarily be. For actual handheld weapons, keeping them in good, sharp condition is kind of a priority, since it's small comfort to know the dude you scratched had a bad time a week after he partitioned your ass like it's Poland. Of course peasant armies often went to war with whatever pokey tool they had, and you can absolutely get tetanus from getting stabbed by a hay fork or a straightened scythe. Against armored opponents, sharp weapons are of little use, so knight vs knight combat would have been maces and hammers mostly, and those don't do deep stab wounds anyway (except war picks and morning stars

Tetanus is not related to rust. Tetanus lives in the soil outside and only infects you if the object you get stabbed by was outside, exposed to contamination by rain splatter and such. Exposure and rain also happens to make metal rusty. Getting tetanus from a rusty nail outside is correlation not causation. You can also get tetanus from a completely rust free garden tool if you stab yourself with it.

Depending on the country, nothing stops people from declaring anything. Trying to actually act on it however tends to invite a lot of dudes with guns and explosives to help your body parts declare independence from each other.

If it's just that then it's no issue, in fact it is integral to how CUDA works (I'm assuming loop step is constant over one run of a loop). You get the index of the current thread and you can use it - for example the CUDA prime check example is "check the first N integers for primes" -> start N threads and do a prime check algorithm on the thread index. The only problem happens if your loop #n+1 uses data calculated during the #n loop.

A GPU can do a shitton of data-parallel stuff. If you find yourself doing the same operation over a ton of data points, it's worth thinking about whether you can do it all at the same time. Since you are doing python, check Numba https://carpentries-incubator.github.io/lesson-gpu-programming/03-numba/index.html

> It is completely conventional python code.

So, you're not doing any GPU compute at all? Only CPU? See if your algorithm can be parallelized on a GPU (a good sign that you can do so is doing the same operation over elements of huge arrays where computing the result depends only on the input array - a convolution is such, trying to do fill a vector with a fibonacci sequence is not).

Ever heard of Second Life? It's basically an online 3D role-playing game where you can make an avatar character and go hang out with others. Zuck wanted to make a Facebook-flavored VR version and marketed it hard to companies as the "future of customer engagement". Zuccboi just happens to have forgotten to check whether people are actually stoked about spending a thousand dollarinos for a VR kit only to spend their time in 3D Facebook Advertisement-Land. So, you know, people who would have been interested stuck to their usual haunts in SL, VRChat etc.

Of course it didn't help that when their actual software came out it had such shitty graphics that it made early 2000s games look photorealistic.

From low orbit the rotation is basically unnoticeable. The ground moves under you at 400-something m/s but you yourself are flying by at 7000+ so you're just trying to spot the ground move by under you slightly slower than expected.

Of course at near GSO you'd observe the earth being almost completely motionless because you have almost the same rotation period over it as the surface (you'd get to watch the dusk/ dawn line move over the surface at the expected speed though)

You don't crack passwords sitting in front of the login prompt. You use some exploit that lets you get into the backend of the system without the password then copy the whole ass database to your own computer. Or you do some social engineering and ask somebody who has a password that lets you get at the database to tell you. From there you can poke at the hashed (hopefully lmao) passwords at your leisure.
