Another great shout out to @vermaden for this thorough introduction to #FreeBSD, especially if one is coming from #Linux. It may be several years old but much of the info is still relevant today.

The FreeBSD Handbook is great but the additional details and context for the topics covered are where this document really shines.

This needs to be required reading for anyone curious about the OS.

Wie aus einem Backup-Problem BackupPilot entstand

BackupPilot entstand aus dem Wunsch, die Nutzung des Proxmox Backup Clients für Linux-Anwender einfacher zugänglich zu machen. Der Artikel erzählt, wie aus einem internen Werkzeug der OneSystems GmbH ein Open-Source-Projekt für Desktop- und Server-Systeme wurde.

Wegen Systemüberlastung hab ich vorhin den Rechner leider mit eingesteckter ext. Festplatte notausgeschaltet. Hatte sich aufgehängt.

Jetzt komme ich immer nur bis zu diesem Bildschirm hier und wenn ich Manjaro anwähle, kommt lange nichts (schwarz), dann wieder das hier.

Mit Stick booten geht. Bevor ich den Rechner aber neu aufsetze, frsge ich mich und euch: Was könnte ich noch probieren?

Starten lässt sich unterbrechen, aber was ich dort machen könnte, weiß ich grad nicht.

My first company, Opera, was built on word of mouth. The same applies to my 2nd company, @Vivaldi. We have never had the means that Big Tech has. In the case of Vivaldi, we have even avoided investors, to not end up like Opera.

We have also made it harder for our selves. We likely could have generated more funds through adding stuff like Crypto, AI or just plain old data collection in the browser, but we choose not to. We are also not an Ad company like most of our larger competitors. Instead we have added a wealth of features and customization.

Now people are starting to understand that just going with Big Tech may be easy to start with, but ends up not being worth it. In fact we now have governments and companies thinking that they need to move away from Big Tech and quickly.

We welcome you all.

I spent just over two years here managing #Linux and #Solaris servers. My #cubicle was just around the corner from these #machines, below flickering fluorescent lights. Exactly what you'd expect from working in the basement of a government building.

While these systems haven't been in use for decades and should have been in a museum, they were still on the books and inventoried annually. 🤦‍♂️

Tip: you can reduce the heat your laptop/desktop computer generates by limiting its CPU frequency.

To restrict all cores to 800MHz on Linux, run one of these two commands as root:

cpupower frequency-set -u 800MHz

echo 800000 | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq

haha. Joke asides, there are few ways to ignore bash aliases. For example, to ignore python alias, type the `command` followed by alias name:
```
command python ...
```
Both \ and " symbols allows you to run real python command and ignore python alias at the CLI:
```
\python ...
"python" ...
```
Or just full path:
```
/usr/bin/python ...
```

This is meme about Linux or Unix CLI especially alias feature offered by bash. An inmate in prison asks a small fellow inmate, "What you in for?" The small inmate replies that they added 'alias python=echo "bash: python: command not found"' to a friend's .bashrc file. The large inmate backs away in terror, yelling, "Dude, WTF?!"

What’s stopping you from building a nice little home lab running multiple VMs, a personal DNS resolver with Ad blockers, a ZFS based NAS and firewall with #Linux or #FreeBSD? 🤔

Just finished building the major Slackware updates (Plasma 6 plus a huge number of core package updates) under Open Source UTM using paravirtualised mode on Apple Silicon M2.

UTM has been absolutely rock solid throughout. Had to revert to the HoneyComb LX2 (16×2GHz cores, 32GB RAM) tho, because I couldn’t dedicate enough memory to the VM -- the host’s OOM killer started terminating some of the large KDE package builds.

Dreaming of a Mac Mini M4 for the main build host...

#linux #slackware

After Bluesky, Threads, and so on, the whole #WSocial thing is another reminder that it was never about the #Fediverse being "too complicated" or "just for nerds".

A bafflingly large amount of people genuinely only act on a gut feeling telling them that only commercial products with fancy marketing owned by a for-profit corporation can be trustworthy, 'official' and 'legal', for the lack of a better word.

If something is a commercial offering by a competent-looking, rich family man in a suit, it's clearly an official, legal, trustworthy product. You can be proud of using such a fancy-looking service.

When they see a community-run open-source project or a grassroots initiative, their first instinct is that it must be shady, illegal, complicated, broken or predatory in some way. It's probably some aftermarket grey area bootleg made by weird tech nerds, political groups with an ulterior motive, conspiracy theorists or some naive teenage hackers. They'd also be embarrassed for using it in front of their peers and neighbours; who uses some free back-alley software, are you poor or something?

The same people are the reason why Google is using the word 'sideloading', why scammers love wearing fancy suits, why people suddenly act childishly helpless in front of LibreOffice, or why DIY HRT is so demonised.

They trust any kind of 'official approval' over their own senses. If someone does something that isn't 'approved', they're a bad person or clearly endangering themselves and others. No idea why exactly, but psh, it must be wrong somehow, or everyone would do it, right?

If people on the Fediverse understood that the whole "it's all so complicated and clunky" thing is just a thinly veiled excuse for a general disdain for non-commercial software, we could finally stop making all our software imitate their corporate equivalents in a futile attempt to appease people who never gave us a chance in the first place.

You'll never convince them to treat it in good faith no matter how much effort or money you put into UX or 'ease of use'. All you're doing is making the software worse, e. g. through things like dot-social, verified accounts or begging brands, corporations and politicians to join and give your product some kind of 'official' validation.

Thx to AI Linux will soon stop being a platform for retrocomputing hardware. Old hw support is getting deprecated to reduce the attack surface.

Meanwhile the Linux Foundation is creating its nth AI/crypto related group.

I think #linux was already heading in that direction, but I guess with #ai it will speed it up. From my perspective #linux is owned by large corporations and regular users are a very low priority.

There is always #NetBSD :) I am on 11.0 RC5 on a #T430 and it is working great, granted you have to pay attention to the hardware you use/find/but. Plus #NetBSD seems to be dedicated to keeping old hardware out of landfills.

Rust is becoming a major part of the #Linux kernel. Even long time C veteran Greg Kroah Hartman (GKH) supports the shift. Rust is next big thing if you are into kernel or device drivers or other stuff where memory safety is essential for security reasons

Security Advisory: CVE-2025-70102 - NULL Pointer Dereference in dhcpcd parse_option

Summary
A crafted dhcpcd configuration input can trigger undefined behavior in the configuration parser by causing `parse_option()` to access a member through a NULL `struct dhcp_opt` pointer.

The issue is located in `src/if-options.c` in `parse_option()`. During parsing of malformed or unexpected option data, the lookup/parsing path can leave the local DHCP option pointer unset. The affected code then assumes the option pointer is valid and accesses embedded option metadata through it, which results in a NULL pointer member access at `src/if-options.c:1886`.

CWE:
CWE-758 - Reliance on Undefined, Unspecified, or Implementation-Defined Behavior

Affected Component:
```
src/if-options.c:1886
Function: parse_option()
```

Affected Product:
dhcpcd

Affected Version:
The issue was reproduced against dhcpcd commit:
```
2de751b3691642151a4fdc49e444d6b4dc364e98
```

Attack Conditions:
An attacker must cause dhcpcd to process a crafted configuration input that reaches the vulnerable option parsing path. The issue was reproduced in an instrumented fuzzing build of the dhcpcd configuration reader.

Impact:
The vulnerability causes undefined behavior and process termination under the sanitizer build, resulting in Denial of Service. No evidence of arbitrary code execution was observed in the local crash data.

Fix:
The issue was fixed in dhcpcd commit:
```
117742d755b591764036dd4218f314f748a3d2b7
```
The fix ensures that the pointed-to local DHCP option entry is non-NULL before it is dereferenced. Users should update to a dhcpcd build containing this commit or later.
