I do love it when people find, and favourite/boost, my posts from years ago. For some reason my post from 2019 about the "ultimate cheat sheet" suddenly got some love.
As far as I can tell, the cheat sheet has been continuously updated, and is still relevant.
Check it out!

Hey jerks, the only time someone will see this particular
message is if they are running xscreensaver with '--log'
to order to send me a bug report, and they had damned
well better try the latest release before they do that --
even if your perma-out-of-date distro does not make that
easily available to them.

hey so this is probably completely pointless but: looking for a job (NZ or fully remote willing to hire a kiwi) in SRE, security, or linux/Unix system administration. 15 years expereince administering Linux and Unix boxes, intermediate level of experience working with docker compose and containerisation and container security. No prior job experience unfortunately, all those 15 years were mostly personal projects and small-scale stuff for friends. Currently running an entire multi-machine personal cloud infrastructure with a demonstration of all the services I have running at https://status.highenergymagic.net. Entirely willing to accept entry-level job placements, no expectation of being paid a lot or anything, just want to be doing something and move the needle a little on my current "being broke" status. #fedihired #infosec #cybersecurity #linux #unix #docker #sre #DevOps #GetFediHired

"How it all began"
I saw an ad for this CD set at a very low price in a computer magazine. I decided to give it a try, enticed by the low cost and this 'alternative solution to Windows', and in late 1996 I ordered this set.
When it arrived, I was fascinated (having never used a Unix or Unix-like system before) but a bit daunted by the lack of support for the main applications I knew. A few months later, though, I decided to give it another go and from that point, I never looked back. Whether it was Linux, one of the BSDs, or something similar (but Unix or Unix-like), I was not going back to systems like Windows.
My #ThrowbackThursday today is probably one of the most significant in my computing life.

This is a photo of a 6-CD set case for "InfoMagic LINUX Developer's Resource". The CD case cover has a whimsical cartoon character on the front, which appears to be an anthropomorphic penguin dressed as a wizard, complete with a wizard's hat and a magic wand. The character is standing on a stylized representation of the globe. The background is blue and there is a yellow banner on the top right corner that says "QuickStart Guide inside". The packaging suggests that this is a software resource kit for Linux developers from the era when software was commonly distributed on CDs.

This is a photo of the back cover of the "InfoMagic LINUX Developer's Resource CD-ROM" case. The cover lists the contents of the 6-CD set, including distributions like Red Hat 3.0.3 "Picasso", Slackware 3.1, Debian GNU/Linux 1.1.4, and others, with various kernel sources up to version 2.0.12+. It mentions the inclusion of a "QuickStart" installation guide and additional software like X-Free86 Version 3.1.2, with references to online resources. There's also information about the included on-line documentation like "Installation & Getting Started Guide" by Matt Welsh and "Network Administrators Guide", as well as file format details. Contact information for InfoMagic, including telephone, fax, email, and web address, is listed, along with the company's address in Flagstaff, AZ. A barcode is present on the bottom right. The text indicates the product is from 1996, providing a glimpse into the distribution of Linux software in the mid-1990s.

I found this ad for a six-degree-of-freedom 3D input device in the Summer 1989 issue of the SGI magazine "IRIS Universe".
I remember seeing stuff like this around in the 90s, but it all seemed so inaccessible at the time. Flipping through these old professional magazines, you spot some interesting engineering and industrial design.
@flexion, you should get one of these, restore it, and get it working on one of your systems.

Did quite some maintenance on burningboard.net Mastodon instance today ..
Updated servers and jails to FreeBSD 15.0-RELEASE-p5
1.
proxy_cache_path (S3 media cache) was already on a ZFS dataset with autosnapshot disabled .. But proxy_temp_path and client_body_temp_path (both nginx temp folders) weren't. Leading to extremely bloated daily ZFS snapshots for the Nginx jail. Changed those and cleaned old snapshots -> 31GB reclaimed space
2.
Cleaned up Database Snapshots and did a pg_repack on prod to reclaim deleted database pages -> 3GB reclaimed space
3.
Fixed issue with backend path over gif tunnel to Elasticsearch (6in6). Turned out to be a MSS issue (clamp-mss to 1140 solved it!)
4.
Fixed IPv6 routing issue for Prometheus Monitoring after reboot (rc.d static_routes != ipv6_static_routes)
All in all, our instance is in very good shape again :-)

Sorry for my previous rant, but Richard #Stallman has been predicting this since *decades* from their libre ITS machines suffering corporate bullshit forever. Their own GNU project was to liberate #Unix from the #AT&T hands. Yes, it was and it's a bit bloated from the #BSD perspective, I know, I was an OpenBSD user and now #9front, but #hyperbolaBSD will try to fix that: minimalist BSD freedom with a #GNU license. And you might not need to suffer FFSv2 fscking itself again ;) as a plus.
So you if you now need a free #Unix, you know what to support. Consider anything from #Redhat/#IBM ultimately tainted. #Trisquel
it's sadly on a razors' edge. They will patch it... until they can't anymore.
#GNU #Guix it's fine, but better if you pick it bia Bittorrent under a non-US mirror.
If you want a Unix 2.0, head to #9front, but help with ath9k drivers (there are none) as they are the only ones without needing binary blobs (less opaque things to debug and a total freedom to distribute them with base).

New post: shell tricks that aren't exactly secret, but aren't always taught either.
Split into two sections: what works on any POSIX sh (FreeBSD, OpenBSD, Alpine...) and what's Bash/Zsh-specific. Because not everyone is on Linux with bash as their login shell.
Things like CTRL+W, $_, pushd/popd, fc, set -euo pipefail caveats, and more.

I am almost sure the AT&T 3B2/600 SYS Vr3.2.3 did not have this system call.
I read & tried to memorize all the system calls in 1992 (from a giant binder that came with the 3B2) and I do not recall ever knowing profil() existed.
That also has Ken Thompson's fingerprints on it. He does regret leaving 'e's off all the time, apparently.
I am glad you are creat()'ing some historical records of early #Unix history.
But maybe give the people who got history wrong in man pages a sysbrk()?
The #Linux man-pages profil(3) says
HISTORY
Similar to a call in SVr4
bruh, it's identical to the call that's been there since Research #UNIX v5 (OK, except that in v5 you disabled profiling by passing scale=0, while on Linux you disable profiling by passing buf=NULL; but in practice the common way to call it is profil(0, 0, 0, 0) so it doesn't really matter which arg it keys on).
(#OpenBSD profil(2) correctly states v5, #FreeBSD profil(2) claims it goes back to v3, but I think the evidence for that is dubious.)
Run the following to see your PATH settings in easy to read format on screen:
```
tr ":" "\n" <<<"$PATH"
tr ":" "\n" <<<"$PATH" | lolcat
```
This is a little more portable

echo "$PATH" | tr ":" "\n"
echo "$PATH" | tr ":" "\n" | lolcat
```

a screenshot showing output of the `tr ":" "\n" <<<"$PATH" | lolcat` command to see your system's PATH environment variable in a readable and colorful format using lolcat command. This command will print your system's search paths using the `$PATH`, lists them one per line, and makes them look pretty just for fun. You can skip the `lolcat` bit if you don't want colors.
Part 2 of the FreeBSD Foundationals series is out! "ZFS - The Last Filesystem You'll Ever Need."
We go from the philosophy of silent data corruption to practical, battle-tested data management. Covers pools, datasets, why you shouldn't blindly add L2ARC, native encryption, and using sanoid/syncoid to turn backups into a solved problem.
If you've ever lost data and decided "never again," this is for you.

New series: FreeBSD Foundationals
Part 1 is about Jails - specifically VNET Jails. What epair interfaces actually are (virtual ethernet cables), how bridges tie them together, why the host is basically a router for your jails, and what devfs rulesets control.
Covers the full lifecycle from jail.conf through pf firewalling with NAT/RDR for IPv4 and direct routing for IPv6. Plus the gotchas that'll cost you hours if nobody warns you.
Not a beginner tutorial, hardcore details. The useful middle.

They have assumed that all operating systems are like Microsoft Windows 11, Android, or iOS; and have written legislation for operating systems where people download glorified WWW client 'apps', from 'stores', which use 'accounts' that they have with vendors or Microsoft/Google/Apple.
But the legislation *as worded* *also* covers everything from #Debian and #Ubuntu through #Arch Linux and #MobaXTerm to #FreeBSD and #NetBSD and #OpenBSD; where users anonymously use package managers or ports systems to install applications, written by developers, on operating systems, from 'publicly available internet website' repositories.
There is no age field in the GECOS data in master.passwd(5) of course, and the reality is that no BSD or Linux-based operating system has this concept of apps/stores/accounts.
