  • Theoretically cryptocurrencies are interesting, but Bitcoin just isn’t usable.

    Bitcoin and many other currencies have way too many and large fluctuations in value for daily use.
    Bitcoin specifically is not practical for transactions in general due to cost and block size limits. Yes, lightning exists, but maybe your technology is shit if it needs a second overlay network to function.
    Instead of fixing those issues, most other coins are just pump and dump schemes for a quick buck.
    Only very few coins try to do something different and fix some of these issues.




  • Open UDP ports are pretty secure and rarely found by scanners. The basic issue with scanning for UDP is, that most services don’t respond to random garbage you try to probe then with. Without getting a response back, the scanner has no way of knowing if there is something running on that port or not.
    Wireguard in particular only responds if the correct key is given.
    Also make sure your firewall DROPs (usually the default, but do check) disallowed connections instead of REJECT. This way any UDP probing, whether it’s to an open port or closed one just times out with no way for the scanner to distinguish them.








  • It will be the workers, with their courage, resolution and self-sacrifice, who will be chiefly responsible for achieving victory. The petty bourgeoisie will hesitate as long as possible and remain fearful, irresolute and inactive; but when victory is certain it will claim it for itself and will call upon the workers to behave in an orderly fashion, and it will exclude the proletariat from the fruits of victory. … the rule of the bourgeois democrats, from the very first, will carry within it the seeds of its own destruction, and its subsequent displacement by the proletariat will be made considerably easier…

    In my experience setting environment variables is pretty inconsistent. The easiest way would be using /etc/environment. This sets stuff globally for all users and definitely works.

    PAM also used to support a per-user environment file, but that’s deprecated or removed even. The best you can do for per-user config is setting variables both in your login shell and the systemd user environments file.
