    Other Hello world Golang script

    She-bangs are weird! The only issue is you can't use /usr/bin/env https://lorentz.app/blog-item.html?id=go-shebang TL;DR: /*usr/local/go/bin/go run "$0" "$@"; exit; */ package main import "fmt" func main() { fmt.Println("Hello world") }

    GMKTek Mini PC with Intel N97

    Don't purchase from the GMKTec store. They tell you they take care of VAT. They don't. It's a fucking mess and they don't send an invoice but charge your credit card nonetheless.

    Programming book porno

    This is really obscene. I had to sell or give away mine. And Kindle sucks.

    jails Security audit of jails (39c3) done by Ilja van Sprundel

    There's an argument that this doesn't achieve much: https://isopenbsdsecu.re/mitigations/karl/ Note: I don't condone the above site given the garbage reasons for targeting OpenBSD (not having a CoC and so on).

    Post some hardware porn

    I had the Phenom X3. The urban legend was that they were triple-core because they failed QA for quad-core. And Windows had to patch their OS so it could run on this processor.

    FreeBSD 15 probably will include KDE as DE installtion option

    This is only the login manager, which itself is a fork of SDDM. KDE helped with OpenBSD support: > Improved and fixed support for OpenBSD in multiple places. https://blogs.kde.org/2026/01/03/this-week-in-plasma-new-year-new-accessibility-features/#notable-in-performance--technical

    FreeBSD on only TTY as a Daily Driver

    There was a time I used the tty exclusively, before having a job while at the univ. I don't see myself checking the smartphone everytime. It's the less exciting piece of hardware I have. I prefer checking Whatsapp/Telegram from my laptop.

    ZFS How to un-ZFS-ify a drive?

    You may want to check what util-linux wipefs does or even call it with `wipefs -a -f $DEV` because I remember dd at the beginning not being enough sometimes. =/

    ZFS How to un-ZFS-ify a drive?

    Using CoW filesystems on devices like USB pendrives and SD cards with no wear leveling is a bad idea due to the write amplification. Someone should tell the NomadBSD guys to add this warning.

    How to determine if SSD is faulty

    Install smartmontools and run `smartctl -x /dev/$disk` LLM's like ChatGPT turn out to be very good at interpreting the results.

    Wrapper around pkg(8) to automatically mount pkg cache in tmpfs and create a ZFS boot environment

    To avoid reinventing the wheel, there are the 3 workflows I know of: 1. Illumos pkg creates a new BE by default except when installing new packages. 2. openSUSE's zypper creates a Btrfs snapshot everytime, even when removing packages, keeping a configurable maximum of 10 snapshots. 3. GhostBSD...

    Wrapper around pkg(8) to automatically mount pkg cache in tmpfs and create a ZFS boot environment

    I know modern SSD's resist a bit more but I dunno about eMMC's. It's also faster to download to RAM. I'm even tempted to symlink /var/cache/pkg to /tmp which is already tmpfs in my case but want to do it in a secure way.

    Wrapper around pkg(8) to automatically mount pkg cache in tmpfs and create a ZFS boot environment

    I'm experimenting with this wrapper around pkg(8) to automatically mount the pkg cache in tmpfs and create a ZFS boot environment. The reason for using tmpfs is to prevent a eMMC/SSD from wearing. Any suggestions for improvements are welcome. #!/bin/sh # # Wrapper around FreeBSD pkg(8) to...

    Please recommend me a good free online course to learn linux or bsd console.

    You can't go wrong with the classics. In addition to The UNIX Programming Environment recommended above I'd also add Advanced Programming in the UNIX Environment by Richard W. Stevens. Any book by this author is a collectible item. Both explain the concepts as well as the implementation...
