When others might be interested in what you have to say. If it's a discussion, them other participants almost always want to receive what you send. However, if you asking a question about an assignment, don't, no one else needs that.
They do it to sound cool. Interestingly, in Japan (often nonsensical) English often gets used as a decoration in a similar way: https://youtube.com/watch?v=V347dTGZVl0
In terms of performance, the best option is multiple wired together access points. You can get flat Ethernet cable that can easily fit under doors, carpets and through windows if you don't want to/can't drill any holes in your walls. Mesh networks are an option, because the mesh nodes generally have higher power transmitters then your device, but this will be slower then a proper setup, and get slower the further you are from a node with a wired connection.
If you are on 5 GHz, try moving to 2.4 GHz, the top speed is slower, but it much better at passing through walls.
Put #define true (rand()%1000 != 0) in some obscure C or C++ header file on their system/project. This makes true evaluate to false one in a thousand times, and will make them spend hours trying to figure out why things like infinite loops, aren't quite infinite.
Other languages should also allow you to do things like this, if not messing with constants, messing with standard library functions.
One, people can make their own guns, it's not that hard, and secondly, criminals can and do steal stuff. They don't care about commiting extra crimes, they are already going to jail if caugh. All this will do is to make it harder for non-criminals to obtain guns for hunting or self defense.
The GDPR is not "cookie law", it only prohibits tracking users in a way not essential to the operation of the site using locally stored identifiers (cookies, local storage, indexed DB...)
Storing a cookie to track login sessions, or color scheme preference does not require asking the user or allowing them to decline.
Nearly all of these are illegal, but sadly there is little enforcement when it comes to this. (Tracking must be opt-in, not opt-out. Ignoring a banner must be interpreted as declining. Opting out must be a simple option, not navigating a complex and misleading menus. The users choice applies to any form of tracking, not just cookies...)
Ok, as a compromise between a generic word and a specific name, I vote we call them Xcrement. (Verb: Xcrete) (Would nicely describe the average quality too)
They did, with core you could be paying for many dollars per bit of memory. They also often used teletypes, where you would pay in ink and time for every character.
Hell runs on Linux so it never freezes.
