And of course, as it's Cambridge, the beer festival is sponsored by a #Linux debugging tool.

What I'm still missing is a custom #recovery that can actually do any useful stuff (especially full #backup).

My device has recovery as a #ramdisk in vendor_boot, and there are some prebuilt vendor_boot images with #twrp around, which I don't want to use directly because there's also an init-boot ramdisk in there that needs patching for root with #magisk ... and as far as I understood now, these ramdisks are userland only, using the shared #kernel from the boot partition, so it's unlikely a recovery built for #HyperOS1 (#Android 14, #Linux 5) will work with #HyperOS2 (Android 15, Linux 6).

What I *did* try nevertheless was modifying my vendor_boot using Magisk's #magiskboot utility, replacing ONLY the recovery ramdisk. It resulted in #bootloop trying to boot the normal system, so there seems to be something I still don't understand (I *thought* this ramdisk would only ever be loaded when booting to recovery).

For now, I'll live with the useless stock #Xiaomi recovery. Attempting to do my own build of twrp or orangefox really is too much hassle 🙈

The KDE team has created a wonderful Network for your Androids it's called Konnect (actually KDE Connect) and the things that it can do are so various that I'll just show you one of them in the included photographs

The ease with which I can control a music 🎵 player that works on one Android from all my devices which run Konnect opens up possibilities which are just marvelous for a sound engineer like me

The photograph composed in warm light portrays two smartphones placed on a red fabric with a floral pattern. The phone on the left has a lock screen displaying the time "23:05" and the date "Tue, Apr 29." The background features a vibrant image of a red flower with green leaves. The phone is charging, with a battery level of 82%. A music player widget is visible, showing the song "13_18_21_aug_2021_19Lyntr" by "RadioAzureus (Musicolet)" with a play button and a progress bar. A notification from Mastodon is also visible, mentioning the user by Luca Sironi. The phone on the right shows a similar time "23:05" and date "Tue, Apr 29." The background is dark blue, and the music player widget displays the same song and artist. The weather widget shows "26°C MonPlaisir" with "Clear" conditions. The battery level is also 82%, and the phone is connected to "GSM provider." Both phones are displaying the same time, indicating they are synchronized.

At this moment I'm roughly tuning a very nice FluxBox Desktop in an OpenSource POSIX driven OS.
I'm working on tuning my Desktops Environments in such a way that it doesn't matter whether I run them in Linux or *BSD

That way I'll just fire up the Operating System inject my own configuration for the desktop environment fire up X.org and then start working

FluxBox has been a favorite window / desktop manager of mine a couple of decades ago.

Since it has been written efficient it's blazingly fast
I combine tools that I love from Xfce with FluxBox so that my muscle memory for shortcuts can be used in a super smooth manner

#FluxBox #Xorg #Desktop #Environment #OpenSource #POSIX #GNU #is #not #UNIX #Linux

Since this command...

`xfce4-screenshooter -S -d 2 --window -s "$HOME/Pictures/$(date +%Y-%m-%d_%H-%M-%S)_Screenshot2.png"`

...segfaults in fluxbox atm I did not bother with a screenshot, because xfce4-screenshooter rocks way too much to use another one

I've been able to configure KDE to my liking so that I feel at home again in the K Desktop Environment.

This is critical because it means that everything from way back in the beginning, decades ago when KDE was released, is still in the current new and fresh version of the K Desktop Environment

It means that the teams which have worked on KDE for the past decades have kept the core of KDE alive

It means that we have an excellent group of programmers, before and current, who have worked on KDE and who have kept KDE beautiful fantastic and magnifique for a wide range of people all over the globe

The photograph composed in total darkness shows an IPS LED computer screen displaying the K Desktop Environment with a dark blue theme. The screen is divided into two main sections: the top section shows a settings menu with various options such as "Audio and Sound," "Display and Monitor," "Input Devices," "Hardware and Devices," "Network," "Settings," "Connections," "User Feedback," "Online Accounts," "Accessibility," "Region and Language," "Notifications," "Personalization," "Search and Shutdown," "Shortcuts and Startup," "Workspace Behavior," and "Appearance." The bottom section features a wallpaper of a gorgeous woman standing in a room with a wooden floor and a window in the background. The woman is wearing a white top and a black skirt with a lace pattern, and she is smiling. The screen also shows a sidebar with options like "General," "Global Themes," "Connections," "Appearance Style," and "User Style." The time displayed on the screen is 22:38, and the date is the 15th of May. The overall image is in subtle Bokeh, because of the translucent effect programmed in KDE The screen is surrounded by a dark background, and has been captured with a puny Android analogue sensor smaller than the tip of my Pinky nail Ovis2-8B 🌱 Energy used: 0.264 Wh

I've easily & smoothly configured KDE Konnect to work in Fluxbox WM

Multiplexing will boost your SSH connectivity or speed by reusing existing TCP connections to a remote host. Here are commands that you can use to control multiplexing when using OpenSSH server or client on your Linux, macOS, FreeBSD or Unix-like systems. Not sure what SSH multiplexing is? Learn how to set it up and use it to speed up your SSH sessions with our handy guide: https://www.cyberciti.biz/faq/ssh-multiplexing-control-command-to-check-forward-list-cancel-stop-connections/

List of ssh command to control an active connection multiplexing process on Linux or Unix such as: Valid commands are: “check” (check that the master process is running), “forward” (request forwardings without command execution), “cancel” (cancel forwardings), “exit” (request the master to exit), and “stop” (request the master to stop accepting further multiplexing requests).

You know how for ages, Unix systems let you specify which editor other tools should invoke via the $EDITOR and/or $VISUAL environment variables, falling back to a very sensible vi(1) (or even ed(1)).

The value of that environment variable is used by e.g., pw_edit(3) from vipw(8), notably via execvp(3), so e.g., 'EDITOR="cmd; vi"; vipw' does _not_ lead to the execution of 'cmd'.

Makes sense, right?

Internally debating whether I should pick up a #ThinkPad T43 and using it as my main #NetBSD machine. Currently I have an X260 running #Slackware and an X1 Carbon 6th gen running #CRUX and #Debian but I don't have a machine I can dedicate solely to NetBSD. I also got my Raspberry Pi 4 running #SlackwareARM. I've always just had to run NetBSD in a VM, but I don't wish to anymore. Is it a worthwhile endeavor?

To clear the terminal after logging out, here is a method that works in all modern shells (I'm using `ksh`).

Add to `~/.profile`:

test -f $HOME/.exitrc && trap ". $HOME/.exitrc" EXIT

Create `~/.exitrc` with:

type clear >/dev/null 2>&1 && clear

Useful!

Google Chrome was not following the notification spec on Linux for years. This went unnoticed by most of users as services worked it around to accommodate Chrome.

@dnkl took the stand with his notification service that notifications from Chrome wouldn’t work until they followed the spec. After a few years this led to Chrome getting patched to follow the spec.

I've been talking about it for months, but I finally followed Jami Kettunen's instructions and got Chimera Linux installed in my Yoga Slim 7x ARM laptop.

Windows was crashing every few days (while unattended) with the error "The system has rebooted without cleanly shutting down first. This error is caused because the system stopped responding and the hardware watchdog triggered a system reset." even after a full restore.

I'm hoping Linux is more stable.

Just released: #swad 0.7! 😎

Swad is the "Simple Web Authentication Daemon". If you're looking for a solution to add cookie/form #authentication to your #nginx reverse proxy, or maybe even a #lightweight alternative to #Anubis which leaves the actual proxying to nginx, this might be for you! It is designed for use with nginx' auth_request, written in pure C, with minimal dependencies (zlib and, depending on build options, openssl/libressl and/or libpam), and compiles to a small binary (currently between 150kiB and less than 300kiB depending on compiler and target platform).

Swad should work on many #posix (and almost) systems. It's actually tested on #FreeBSD (in "production" use, but on a very low-traffic private site), and quick functionality tests also done on #Debian (#Linux) and #OpenIndiana (#Illumos, open-source #Solaris descendant).

As announced, this release doesn't bring any new features (in terms of WHAT it can do), but great improvements "under the hood", that should help performance at least on some platforms, see release notes for swad 0.7.

Read more, and download the .tar.xz (to build and install it 😆) here:

Here is a quick useful tip for developers and sysadmins/devops folks. Install `dnf-automatic` package on your RHEL/CentOS/Rocky/Oracle/Fedora or Alma #Linux to automate updates and patching:

sudo dnf install dnf-automatic
sudo systemctl enable --now dnf-automatic.timer

This simple tip can help you manage your packages more efficiently and keep your system up-to-date with less manual intervention, which is especially useful when you are on holidays. See https://www.cyberciti.biz/faq/install-enable-automatic-updates-rhel-centos-8/

So apparently on #Linux, usernames starting with "0x" are interpreted as hex numbers under certain circumstances. 🤪 That seems like asking for trouble...

Quick tip: You can use the last argument of the previous command at the CLi. The syntax is:
command1 !$

For example, make a new dir:
mkdir foo_dir1

Then:
cd !$

which becomes cd foo_dir1, thus saving you typing time. Give it a try.
