• Self-hosted email absurdities – public Wi-Fi

    I recently had to travel and use the internet in random locations without the availability of my carrier’s mobile signal. On some public Wi-Fi hotspots, I was unable to send an email. Now of course I thought the problem lies with my server. Who in their right mind would block outgoing destination ports 465 and…


  • Self-hosted email absurdities – sending mail

    Sending email is hard. Yes, that’s right. If you don’t own or control your whole IP subnet and have built-up reputation on it, you aren’t reaching anything other than the recipient’s spam folder. This is why many admins are even saying that self-hosted email is dead, which is partially true. This would make one of…


  • Lock the screen automatically when it turns off on Windows

    I hate how the lock screen works on Windows. This is perhaps an oversight and for me a security issue, so I’ll share some information on how to make it work better. This applies to pretty much all Windows versions in use today as far as I can tell. By default, when Windows turns off…

This article is about what software I chose, which software it replaced as well as reasons why this was done. Oh and…


  • Forza Horizon 5 performance hit on VFIO system

    I am trying to document how much of an impact VFIO has on gaming performance. More benchmarks will come in the future, but for now, let’s look at Forza Horizon 5.

  • Moving many btrfs subvolumes to another disk

    As I was migrating my whole system over to btrfs the other day, I came across my docker volume which was already btrfs and using subvolumes. This was of course intentional, however, I had no idea how to properly move those subvolumes to the new disk. Surprisingly, it was somewhat easy. Btrfs has send-receive functionality…


  • How to set Bixby button to turn on flashlight on Galaxy phones

    So we have that somewhat useless Bixby button on Galaxy phones. Now I am not against Bixby, quite the opposite. But I prefer to summon her via voice and use the button for something I commonly need to happen fast – turn on the flashlight. The reason for writing this tutorial is that it was…
