Happy to share that #BoxyBSD remains up!

Recently I got asked about my @BoxyBSD project, which offers free VPS instances of vary #BSD based systems for learning and educational purposes and I'm happy to share that this projects remains available. Several things could finally be clarified to continue this service to make sure people can learn and practice on real #FreeBSD, #OpenBSD, #NetBSD systems to #RUNBSD. Also, BoxyBSD starts moving over to #Sylve on #bhyve.

But not only that! We could also get some more new resources and locations to scale and this also brings up another new project for #free Linux #VPS instances at https://boxedtux.com (Fedi: @BoxedTux) where people will be able to learn and practice on different #Linux based distributions (e.g., #Debian, #Ubuntu, #Rocky,...). BoxedTux utilizes #Proxmox clusters as a foundation.

Hope you like this small update... Over & out!

To anybody using both linux and macOS regularly. How do you overcome cmd/ctrl chaos? Does it get better?

I used to only use linux every so often, but now I'm pretty much 50/50 and it's a bit painful

It's been a while since I posted here, and at this point all of my previous posts have auto-deleted. Might as well reintroduce myself.

I am Gabriel, and I am based in Costa Rica. I work as an independent software developer and systems administrator.

As of late, my computer interests lie in #selfhosting, #Linux, and #containers. I care a lot about #privacy and ownership of our data and devices.

I am also passionate about #permaculture, #reading, #cycling, #fermentation, and #synthesizers.

No, an AI-focused "Windows 12" is not coming this year — false report gets the facts completely wrong

> A new report has caught the internet's attention, claiming that Windows 12 is coming this year and will be a modular, AI-powered OS. Here's why that's wrong.

Still credible from Microsoft seeing how fast their enshittification goes nowadays. Don't wait for it. Start using Linux now if you can.

Logic bug in the Linux kernel's __ptrace_may_access() function (CVE-2026-46333) https://lobste.rs/s/nwdn3w #linux #security

Not a single one of these LPE have been called Fraggle Rock. Yet. Disappointed. #linux #cve

Added some follow-up observations to my notes about Transparent Huge Pages (THP) on modern desktop Linux systems.

After ~1 week using:

[always] madvise never

on Slackware-current with Firefox-heavy workloads:

- no swap usage
- no THP fallback allocations
- no compaction stalls
- stable desktop responsiveness

Modern kernels appear to handle THP significantly better than older Linux generations, especially on systems with enough RAM, zram, and NVMe storage.

CVE-2026-31431: Copy Fail https://lobste.rs/s/ksg1es #linux #security
https://retr0.zip/blog/cve-2026-31431-copy-fail.html

Reading an old UNIX Review article from September 1984 about
termcap. Fascinating how much modern terminal software still
inherits ideas from this era.

vi depended heavily on terminal capability databases to remain
portable across different hardware terminals. Bill Joy originally
wired vi only for Lear Siegler ADM-3A terminals, and termcap was
born from the flood of requests for support on other hardware.

"Termcap Unveiled" by Douglas R. Merritt, pages 42-48.
https://archive.org/details/Unix_Review_1984_Sep.pdf/page/n43/mode/2up

Also updated my nvi notes with a small historical section about
termcap/curses and terminal portability.
