  • It happened to me when I was configuring IP geoblocking: Only whitelist IP ranges are allowed. That was fetched from a trusted URL. If the DNS provider just happened to not be on that list, the whitelist would become empty, blocking all IPs. Literally 100% proof firewall; not even a ping gets a pass.


  • Technical debt means how much work it takes to update legacy solution to a modern solution. E.g. each time a new C++ standard is used, all code written with the old standard should be checked. The work time needed to do this is paying up the technical dept.

    Now, if you are lazy, and didn’t clean up the code, used the easy and sloppy solution, next time you have twice the work to be done. So the dept gets worse, if you do nothing.







  • Until you would have to replace a HDD: +23 hours of nerve racking RAID repair time for 10TB drive at 120MB/s Even with some advanced (like ZFS etc.) system you can’t go around the fact the HDDs are slow.

    And when the HDD fails, you can’t read it. It’s toast. Some cheap non-volatile memory devices are like this too, but good ones go into read-only mode and you can at least attempt data recovery from them if no better option is left.

    I’m liking that it is possible get cheap+good 1TB NVMe devices for less than 100€. The consumer SATA market for large SSDs (capacity over 1TB) is unfortunately quite dry. I need replacement for HDDs and even if the speed is capped by SATA bus it would be an massive improvement.
