  • If your goal is to make mini figures, what you want is an SLA machine. They are much better at making small detailed objects than FFF. However, it will definitely cost more than a cheap FFF machine like an Ender 3.

    The Ender 3 variants are cheap and a great platform if you are OK with tuning/tweaking things. If set up properly they work great and are pretty reliable. But of you want something that works out of the box and doesn’t need any tweaking/tuning, you will probably be disappointed with it.



  • Immutable/offline backups. If you backup to local physical media (HDD/tape), physically disconnect/eject it and store it somewhere safe. If you back up to cloud storage (S3, etc), many of them have immutability options. If configured properly nobody (not even you) can delete or modify the backups (within the specified time period).




  • The TPM releases the key to the OS at boot time. Without that, there would be no way for the OS to load (assuming the root FS is encrypted).

    The key is bound to PCRs in the TPM, which control under what conditions the key can be released. For example, it can be tied to secure boot, bios settings, etc.




  • Palm muting is probably more common with down stokes, but you can palm mute up strokes as well. Start with alternate picking on a single string. Usually you are palm muting all 6 strings anyway, as it’s a technique that is more suited to single strings or power chords.

    Strings stretch most when they are new. After the initial stretching, they don’t change as much. This is why it’s common to manually stretch new strings when you put them on. Depending on the guitar and type of bridge, the tuning of one string can affect the others. For example, if you tune your low E string down, the other strings may go up in pitch as they take up more of the tension.







  • With rootless containers, even root in the container is basically useless anyway because it truly runs as a fake ID on the host.

    I’ve seen this repeated a lot, but I’m not really convinced running as root inside containers is a good/safe thing to do. User namespaces can provide some protection for the host, but that does nothing for the rest of the files inside the guest. For example, consider a server software with an arbitrary file write vulnerability. If the process is running as a low privilege user, exploiting the vulnerability might not really get you anywhere. If it’s running as root, it’s basically a free pass to root privilege and arbitrary code execution within the container.
