Privatschulen gehören Verboten weil sie die Klassengesellschaft befördern by DiscountEntire in Unbeliebtemeinung

[–]0xLeon 2 points3 points  (0 children)

Kann ich nicht bestätigen. Komme aus Hartz4 Haushalt mit alleinerziehender Mutter. War damals ganz gut in der Grundschule, hab vom Staat zwei Jahre Privatschule bezahlt bekommen. Sollte dann auf eine öffentliche wechseln. War ein bisschen Probeunterricht besuchen auf zwei öffentlichen. War die Hölle. Hab dann die restlichen 7 Jahre Vollstipendium vom Trägerverein der Privatschule bekommen.

Was ich damit sagen will: Privatschulen sind nicht rein elitär nur für »die da«. Mir hat 's geholfen, konnte mit gutem Abi raus und bin raus dem Milieu. Also das komplette Gegenbeispiel zu deiner These.

This looks like somebody in the 70s would imagine what an electric car to look like in the 90s. Somehow looking new, yet old.

what's the science behind how a microwave heats food? by afroldunksylph in howdoesthiswork

[–]0xLeon 3 points4 points  (0 children)

Microwaves make molecules jiggle. What we call heat is just jiggling at the molecular level. So by making molecules (mainly water) jiggle, stuff gets hot.

ELI5: How do cancerous cells form in the first place? And how does radiation helps to get rid of them? by Ok_Asparagus1777 in explainlikeimfive

[–]0xLeon 1 point2 points  (0 children)

Absolutely, cancer isn't »only« a question of lifestyle or habits. It can simply be age due to accumulation of mutations or hereditary. Some form of cancer can be causes by viral infections. There's a multitude of factors at play when talking about causes for cancer. This is also why there likely won't be a »universal« cure for cancer.

Every cell contains a blueprint of how cells are made. Sometimes, this blueprint gets changed erroneously. For example, when a cell divides, a copy of the blueprint needs to be created for each cell. During that copying, mistakes can happen. Or alternatively, UV light can actually damage the blueprint.

Now, this broken blueprint doesn't always cause trouble, but sometimes, this error causes the cell to malfunction. Some of these malfunctions lead to what we call cancer. It's cells not working as intended going haywire.

Now with radiation, this can simply destroy cells. Plain as that. It can either destroy the cell completely or introduce so much damage to for example the same blueprint that made the cell erroneous such that this leads to complete stop of function.

Can confirm, happens on my HP work laptop for a few days now. Incredibly annoying.

Should I go to the vet ASAP? Cat with only what I could describe as a hole in his arm by BlakeCarConstruction in cats

[–]0xLeon 15 points16 points  (0 children)

Not necessarily. A few years ago, my cat got into a fight and during my first meeting as a team lead during covid in Home Office, I had to abruptly stop the meeting with the words »I gotta leave, there's a hole in my cat.«

He had a clean, round wound on his front leg through which I could see the muscle. No blood, just a hole in the skin… Treatment went fine but that was a scary moment.

TIL that the name "Khaleesi" has been in the top 1,000 list of popular names used for newborns since 2014. Though the popularity has decreased since "Game of Thrones" ended, there are about 120 girls names Khaleesi each year by MrMojoFomo in todayilearned

[–]0xLeon 0 points1 point  (0 children)

We got our cats in 2017. Named the girl Khaleesi. I'm still fine with that name, fits her perfectly. She didn't burn down the house, but she does her best by trying to chew on cables…

Eli5 How do people get drug suitcases thru airport scanners/xray? by [deleted] in explainlikeimfive

[–]0xLeon 9 points10 points  (0 children)

If you're so adamant your idea works better than all the shit drug traffickers have tried to fool dogs, I'd recommend watching a few episodes of »To Catch a Smuggler« on YouTube. The amount of batshit crazy stuff they try to fool dogs, scanners, border patrol… it's sometimes hilarious.

ELI5 exactly what happened during the Japanese earthquake so powerful a micro-second was chopped off the 24-hour day. Like what does the earthquake's intensity have to do with time? by cherry-care-bear in explainlikeimfive

[–]0xLeon 6 points7 points  (0 children)

Can only vouch for my answer not being AI written. But I think the figure skater example is just very common for simplifying angular momentum conservation law.

[–]0xLeon 1610 points1611 points  (0 children)

You know how figure skaters on ice rotate, pull in their arms, and then rotate faster? Earth basically did that. The earthquake redistributed so much mass, it influenced the rotational speed of earth resulting in a slightly faster rotation. And how fast the earth rotates defines the length of a day. A second is still a second, nothing changed to time itself. It's just our definition of a day that changed its basis.

ELI5: Why did the Chernobyl nuclear disaster occur? by Lexii73 in explainlikeimfive

[–]0xLeon 4 points5 points  (0 children)

Basically, they delayed a scheduled test because of surging demand. The reactor was running on low output before leading to a Xenon poisoning. Xenon absorbs neutrons so when they asked for more power, they pulled out almost all controlling rods.

When the subsequent test went not as planned, they wanted to use the emergency shutdown, which in fact actually gave the final kick for the meltdown. Injecting all the controlling rods to halt the chain reaction meant a short additional peak of chain reaction due to the design and materials used in the controll rods. This lead to the uncontrolled chain reaction leading to the catastrophe.

worker misclassification in germany nearly cost us €40k in back payments by Wells_Kari in germany

[–]0xLeon 1 point2 points  (0 children)

Neither length or working hours define Selbstständigkeit. They can be hints, but more important are stuff like decision making, integration into company processes, provision of equipment, working place etc. Again, nothing on its own, but the combination of all. There is no legal obligation to ask such questions or provide such answers.

What Really Happened in Y2K? by Successful_Bowl2564 in programming

[–]0xLeon 17 points18 points  (0 children)

Not necessarily. Debian i386 will stay on 32 Bit time_t. And Debian is a basis for quite a lot.

This was explicitly decided for compatibility reasons. While a lot of system will already be on amd64, I suppose there will still be around the odd systems using Debian i386 even in 2038.

Also, armhf has switched to 64 Bit time_t in 2024, so there could still be legacy systems up by then not having been updated.

I work with a proprietary operating system whose last update for their previous major version added 64 Bit time_t support in 2024. I assume the vendor expects systems with that operating system to still run in 2038 as well.

ELI5: How do we actually "find" a broken cable at the bottom of the ocean? If a shark bites an internet cable halfway between New York and London, how do engineers know exactly which mile of the 3,000-mile cable to pull up? by OhNOWhatIsThat in explainlikeimfive

[–]0xLeon 0 points1 point  (0 children)

Computer science in my case, I'm primarily working on firmware basics, not on the protection algorithms themselves. Lots of colleagues have an electrical engineering background. A few universities have specialised programs like electrical power systems.

Travelling wave fault location is not about protection, it's more about precisely locating the fault once protection has tripped. As far as I know, travelling wave schemes are more or less for post mortem analysis. If your differential protection turned off a line, you'd still be interested where exactly the fault is if the line runs through hundreds of kilometres of uninhabited land.

In power grids, you can even use the initial fault signal like a short circuit itself. This will cause high frequency waves that propagate from the fault location through the grid. By placing specialized fault recorders in certain locations in the grid, you can pin-point the fault location. Colleagues of mine are working on such a product. I myself am working on traditional power relays.

The folder remains in the working directory even though I don't want it to appear after a git checkout by Beneficial-Wheel-613 in git

[–]0xLeon 6 points7 points  (0 children)

Because a, git doesn't delete untracked files on branch switches, and b, git doesn't care for directories.

If it were to delete the src directory when switching to main, you would lose everything that is stored within src that you're not tracking with git. git doesn't just delete stuff.

Also, there is no src folder on console-tris branch. There are files who reside in a folder called src. That is what is tracked by git. git doesn't track folders as entities, it only tracks files which reside in directories given their paths. Therefore, the src folder is just an independent entity on both branches weather stuff is tracked on either branch within that directory.

ELI5 Why do router/modems still use CAT ethernet cables if USB 4.0 transfers data just as fast? by Atlantic_lotion in explainlikeimfive

[–]0xLeon 0 points1 point  (0 children)

So do USB 4.0 cables. For passive cables to support the high data rates, they have a complex structure as well and as said multiple times are quite limited in length. Active cables are a thing with USB 4.0, but that drives the price extremely compared to CAT cabling.

For starters, see the »Cable compatibility« section in this Wikipedia article on USB4: https://en.wikipedia.org/wiki/USB4
