    UFW

    This is just my personal computer and I’m a newbie to configure firewalls

    Leave it alone.

    If you want to experiment, set up a VM and experiment there.

    Also, if you want to learn about Linux firewalls, go for iptables instead. UFW is easier, yes, but you won’t get the standard way of configuring a Linux firewall, though to be honest, unless you are directly connecting the computer to the internet, you probably won’t need to bother.

    And if you are working in an environment where you are dealing with a segmented network with limited access between segments, they will probably already use a separate firewall that is easier to manage centrally than induvidual firewalls running on individual computers

    I remember back when I found the Conet project CD boxset uploaded on the internet when I was into number stations.

    It is a collection of number station recordings, released to try and get attention and focus people’s efforts to find and decode these signals.

    A subtype of number stations are polytone stations, they broadcast tones that a computer can interpret into the message, so when you hear it, it is just what sounds like random tones played randomly at high speed.

    The full recording also has a few more sections, there is often an identification string, like a peice of music to help agents tune in to the source, then there is a sync broadcast to have the computer figure out the timings, I have heard this as a rapid stacato tone signal.

    Anyway, one of the most terrifying experiences I have had with media was when I was at a LAN party, I was playing OpenTTD with my friends in coop, while listening to the Conet project.

    I get to a track that just starts with a slow droning rythm, I zone out from the sound and it is kinda nice with a slow, allmost meditative tempo in my headphones.

    This goes on for minutes as I relax, then suddenly, the sound speeds up and a different stacato rythm starts.

    And before I could react, my ears are filled with weird random beeps at a high speed.

    I just ripped my headphones off my head as it sort of felt as if my brain was being reprogrammed, the long slow drone part felt as if it was made to soften my brain up, for the fast beeps to affect me.





  • I sadly had to get a Reddit account just a few weeks ago, I am an IT technician and needed help from the sysadmin subreddit for a work question.

    But after rejoining after more than a year away from the site, it has clearly seen a huge decline, way less people post less content, the content that is posted isn’t as interesting as it used to be.






  • I don’t have a lot of crazy stories, but I have one unusual story.

    I got to go take a private train with my dad.

    We had one first class car and one locomotive.

    My dad worked in the train industry, he sold equiment used for railroads.

    He called me one day and asked if I wanted to ride a private train, I had time so I gave the only apropriate answer, “yes”.

    So after having worked a night shift I slept far too little, got on the train to the city my dad was in to ride the private train back.

    He was doing a demo of his company’s equipment and had arranged for them to use a private train, I just joined him on the journey to our city as a fun and interesting experience.
