• Recently at work I just did regular work-things. I logged on to my PC, opened my E-Mail client(s), read some mail, SSHed into one of our servers, started VSCode.... all that stuff. However some things were weird. I was looking stuff up on the internet - googling stuff, but some websites wouldn't load.

  • What's inside? How does it work? What else can it do?

  • What happens if you don't understand what the system is doing behind your back

    Transaction fees aren't the only thing. Be careful not to run out of gas.


  • How to start the old Cisco firewall management utility on modern Linux systems

    With our workshop project "Three quarks for Muster Mark" we received an award from Federal Minister Mag. Iris Eliisa Rauskala as part of the culture connected initiative - cooperation between schools and cultural partners.

  • But very little CPU and disk activity. What could it be?

    On one of our Proxmox 6 servers we recently had the issue of Icinga constantly complaining about a high load average. The load average itself is a bit of a weird metric, it measures the length of the run queue. That means how many proceses are waiting to get run - this could either be because they are waiting for CPU time to become available or data to arrive from the disk.

  • Many years ago I "inherited" a website which contains a lot of user generated content. I can't go into details here in order to protect the innocent guilty - and myself.

  • I'm here to annoy telemarketers.

    Do you ever get those calls where people want to sell you stuff? Or tell you about "great" investment opportunites? I heard it's quite common in the US because call termination to the US costs next to nothing - and they have a common language with a country which most of those calls originate from: India.

  • ... or has it? Supermicro isn't sure.

    I mange quite a few servers with Supermicro boards. I kind of like them because the out of band management solution on Supermicro is not the worst thing ever. I haven't found any good remote KVM solution yet, but the solution made by ATEN is at least partially usable. That is, unless you log in to the webapplication, only to be kicked out again:

  • Not by time, but by distance

    "Diiii,diii,diiiiii,chhhhhhh,chhh,shhh ...." - remember those sounds? Those were the sounds of dial up modems when you connected to the internet. Thankfully those times are long gone now. There is no "going online" after 18:00 anymore (because it was cheaper), you're simply connected all the time. In a weird turn of events, instead of connecting to the internet via analog phone lines we're now connecting analog phone lines through the internet, but I digress ....

  • A story of my old 486 notebook. Is it dead or alive?
