Use cgroups or `ulimit -m`.

Why?

Do you need a scientist to flush toilet? Basically, it's same, but for your body.

Only court can prove that something is fake or not fake. Other solutions are vulnerable.

Extreme example: Russian plane was shoot at Black sea in 2001, and Ukraine is blamed by every article in internet you can find, but not by court.

I'm 100% sure that every fact-check organization, except court, will confirm mainstream «fact».

You are welcome! I'm not a native speaker, so it's better to rewrite text into something readable.

You asked.

Good discussion from bad article.

I found surprising link between quantum objects and socks. Socks can be left, or right. They cannot be partially left, or partially right, but they can be left and right at same time! Trust me, I checked that.

Moreover, when nobody is watching, socks are spreading in the room in wave-like pattern. It demonstrates wave-particle duality of socks. However, if somebody watching, socks are demonstrating particle only behavior. Moreover, they are demonstrating particle only behavior even if somebody will watch them in future!

Socks can be entangled, so if one sock is the right sock, then other one is instantaneously collapses to the left sock via spooky action at distance. This feature of socks can be used for FTL communication.

I have theory, it's called «string theory». In this theory, our Universe is made of little strings, which are creating space-time fabric, in which socks are living. In the process of entanglement, socks are somewhat connected by a string, which allows them to communicate via large distances.

Can anybody suggest me how to create a powerful theory from that, e.g. x in power of 10 at least?

Too late, radiation is returned back to almost natural level (about 30% higher than natural). I have detector of radiation, so I can measure it myself. Sometimes wind can bring some radioactive dust from Chornobyl, e.g. after forest fire, but it is much less dangerous.

A small radioactive («hot») dust particle will not change average radiation level a lot, but may cause problems with memory/cpu. Simple cleaning, by blowing dust out, fixes it. Saw that dozen of times, but years ago.

All you need to make FM radio to work is to just connect ground of headphones to a pin, but it is connected to pin anyway, so no extra hardware is required.

Bitflips are not a RAM stability issue, they happen randomly due to radiation, but radiation is not random, especially in my area (I live not far from Chornobyl).

I have no idea, why you downvoted. Stability test is important step of cluster building. If probability of something broken in new server is 10% then probability of something broken in new cluster of 10 servers is 1-(1-0.1)^10 = 65% .

This scripts creates another root, then substitutes /sbin/init using `mount --bind`, then reloads /sbin/init, which pivots into new root with fakeinit.

IMHO, systemd in container mode can be used instead of fakeinit.

I recommend to copy a rescue disk iso image or/and network installation image to boot partition and add it to GRUB menu. This way it is possible to boot into working environment without risk to damage root partition.

Moscow was supplied much often and better than rest of the towns around Moscow, and so forth. It was common practice to ride to Moscow to buy something that is not available locally. Moscow was number 1 in supply line, Moscow region and capital cities of other republics was number 2, European cities are number 3, rest was number 4 or (in practice) even lower, so it was expected that someone in Siberia, far far away from Moscow, never saw a good quality product for his whole life. Butter was example of high quality product, while margarine was low quality substitute which was widely available.
