OMG if only the worlds wouldn't invest in such useless crap... it would probably be a better and more boring world.

Try to fix your own bike before taking it to the shop Updated +Created
Sometimes you get annoyed to death with your bike not breaking or changing gears perfectly as you would like, and the people at the bike shop never do the job well enough.
The problem with bike shops is that the employees are already swamped with work, and they don't get paid any extra for doing more work.
As a result, paradoxically, they are often happier, and respect you more if you are trying to get them to help you to fix your own bike!
Also, for the same reason, they don't have the time to go for a quick test ride after a fix to ensure that the bug was actually fixed.
So they ignore things that would obviously be huge ridability benefits (although they might not be obvious to newbie customers), for which customers would gladly pay more money for.
But you start to learn how to do stuff yourself and it feel amazing when you finally get there (after infinite trial and error).
Ciro dreams of a bike shop that actually calls you for the appointment and then teaches you how to fix the thing.
So the best strategy is to have a backup bicycle, and when your main one breaks, you just try to to the fix yourself. That means:
  • identifying the broken piece
  • watching YouTube videos of how to do the job
  • buying a replacement and any missing tools on Amazon
  • giving it a shot
Then, if you fail to do the fix, that is OK, just take it to the bike shop, with the piece you've bought, and ask them to do it for you. At least this way you did not waste a golden opportunity to learn!
Turing machine acceleration Updated +Created
Turing machine acceleration refers to using high level understanding of specific properties of specific Turing machines to be able to simulate them much fatser than naively running the simulation as usual.
Acceleration allows one to use simulation to find infinite loops that might be very long, and would not be otherwise spotted without acceleration.
Twin prime conjecture Updated +Created
Let's show them how it's done with primes + awk. Edit. They have a -d option which also shows gaps!!! Too strong:
sudo apt install bsdgames
primes -d 1 100 | awk '/\(2\)/{print $1 - 2, $1 }'
gives us the list of all twin primes up to 100:
0 2
3 5
5 7
11 13
17 19
29 31
41 43
59 61
71 73

Country Updated +Created
We shouldn't have countries.
We should have one big global government, with one global language that everyone can speak, and slightly different local laws, so you can choose where to live based on the laws you approve of the most.
Country in Oceania Updated +Created
Covariance Updated +Created
Generally means that he form of the equation does not change if we transform .
This is generally what we want from the laws of physics.
E.g. a Galilean transformation generally changes the exact values of coordinates, but not the form of the laws of physics themselves.
Lorentz covariance is the main context under which the word "covariant" appears, because we really don't want the form of the equations to change under Lorentz transforms, and "covariance" is often used as a synonym of "Lorentz covariance".
TODO some sources distinguish "invariant" from "covariant": invariant vs covariant.

QEMU Updated +Created
The leading open source cross architecture and KVM emulator of the 2010's.
Great way to understand how operating systems work, which Ciro Santilli used extensively in his Linux Kernel Module Cheat.

Cross section (physics) Updated +Created
The neutron temperature example is crucial: you just can't give the cross section of a target alone, the energy of the incoming beam also matters.
