Security through obscurity is a very valid way to secure something. It shouldn’t be the only way of securing something, but it can be a valid additional layer.
The knock sequence is a secret, just like a password. It may not be a particularly strong secret, but is is strong enough to keep out casual attackers. You’ll still need additional security, but sshd is well equipped to provide that.
Depends on where you ride your bicycle.
In the US, bicycle deaths are at 79 per billion miles src. In the Netherlands, this is 17 per billion miles. src.
Note that the Dutch take much more risk when cycling. It is normal for young kids to cycle to school and sports unsupervised. Bicycle helmets are very rare. Despite that “reckless behavior”, cycling is quite safe here. Having dedicated cycling infrastructure really helps.
There are definitely differences between thumbdrives.
First of all, on Amazon, ebay and the like there are flat out fake drives. You can recognize those by the extremely high capacity and low price. They will pretend to have high capacity, but then they’ll just throw away your data. To test if you’ve fallen victim to one of these, copy a very big file (e.g. a movie) onto the drive, remove the drive, reinsert it, and then try to use the file. If that doesn’t work, your drive was fake. Amazon will refund you of that happens, I dont know about ebay and others.
Any name brand will be good enough quality for home use. If you intend to use the drive for backups, spend a bit extra. If you intend to use the drive for just moving files around, feel free to cheap out.
Some drives offer extra security features such as fingerprint scanners. Those are not worth your money.
Extra rugged drives may be worth it to you, but if you’re careful, you won’t need that. I have not found waterproof drives to have extra value, but that depends a lot on how you’ll treat the drive.
In general, you can’t go wrong with SanDisk of Kingston. There are several other good brands, but I don’t want to make this list too long.
I’m not confident it is a Russian op, but Russia has always fueled both sides of the political spectrum. They don’t necessarily want one side to prevail, they just want their opponents to be divided.
In the 1930s, the Netherlands kept detailed records of ethnicity for every citizen. No one thought this was unnecessary, as ethnicity wasn’t something that could ever be used against you.
That line of thought ended when the Germans took over in may 1940. Unfortunately those records still existed, and aided the most efficient genocide in human history. Without those records, many jews, sinti and Roma would’ve been able to deny their ancestry and evade being murdered.
Privacy from government and corporations will one day save lives.
You may not have much experience with spoiled teenagers.
Voicing ones opinion without regard for the people involved, just because they’re allowed to have one, is pretty much the spoiled teenager MO. Just like not realizing this goes both ways.
