At some point I’m planning on releasing the source code and the vector files for the Wordclock face. Have still some cleaning up to do. In the mean time: there are several word clock projects out there that use a Raspberry Pi and Python; just search for them.
To secure it further I just recently installed fail2ban.
The software basically detects login attempts and blocks the IP for some limited time in the future. This prevents a depletive password guessing for server logins.
I was interested in the password-guessers` country of origin. Now I can confirm, at least for my Raspberry Pi, that most attacks come from China.
One of the challenges with bitcoin is to store them securely. There have been severalwellknownincidentswhere Bitcoins have been stolen. It is no mystery. Bitcoin IS money! It’s the same with Euros or Dollars, when you have it lying around it will eventually be missing.
There is a twist with bitcoin to regular money. With Bitcoin one single piece ofinformationis enough for the thief to steal your Bitcoins: Your private key. With Bitcoin it’s about keeping this piece of information secret.
