Bei Wahl der Option User-Autologin ist ein automatisches Öffnen eines Keyrings nicht sicher möglich. Deshalb muss - falls User-Autologin genutzt wird - das User-Autologin abgestellt werden ("autologin-user" Eintrag in "/etc/lightdm/lightdm.conf" auskommentieren).

---

Danach mit "seahorse" einen Keyring anlegen, welcher den Namen "login" trägt (lowercase ist nötig). Das Passwort für den Keyring soll identisch sein mit dem User-Passord. Der Keyring "login" wird dann bei explizitem User-Login automatisch während des Login-Vorgangs geöffnet.

There are at least two places to have a look at, regarding settings, which typically consume a lot of keyboard bindings by default.

• "xfce4-keyboard-settings" (Keyboard settings)
  Goto to tab "Application shortcuts"
  Remove Ctrl-Alt-F, Ctrl-Alt-P, and many others
  
• "xfwm4-settings" (Window Manager)
  To check its bindings, go to tab "Keyboard"
  Here are e.g. Ctrl+Alt+Arrow Keys and Shift+Ctrl+Alt+Arrow Keys predefined (to move window to workspace edges). If you like to reuse those keys in your application (e.g. IDE), then remove those in xfwm4-settings first.
  Also, Ctrl-F1 .. Ctrl-F9 may be removed as they get in the way of IntelliJ IDEA.

It is important to add the icon directly in the Panel Items list, do not try to add it via a panel item called "launcher".
(It only works to add by adding a panel item directly without a launcher.)

Leider ist die Scala Middleware und Web Service Lösung Finagle aktuell nicht für Scala 3 vorbereitet. Der Entwicklungsstand scheint eingefroren zu sein. Die Aussichten auf eine baldige Änderung sind - offen gesagt - eher trüb. Die Firma Twitter scheint anstelle dessen künftig auf Akka zu setzen.
Ein Finagle Crosscompile auf Scala 3 ist jedoch möglich.

GVFS stands for GNOME Virtual File System.
Under Manjaro, if You want create a desktop link refering to a gvfs/samba/smb location, this can be tricky when done with copy & paste with the mouse and modifier keys (alt, shift, ctrl) (copy, move, create link). Personally, for me the easiest and most robust way to accomplish the goal is to use "thunar" file manager, and its right-click-on-file function "Send To", "Desktop (Create Link)". This way a valid reference is created, in the form e.g.:

/run/user/1000/gvfs/smb-share:server=myservername,share=myhostname/myfilepath

---

If problems arise, try adding ",user=myuserid" before "/myfilepath"
with "ln -s targetpath name" a link can be recreated.

---

To analyze if the links are feasible, try "ls -al" in the directory where the links are stored. if the links are not feasble, the color of the "ls" entry will indicate this (e.g. red font, flashing).

Development Maschinen als Client nutzen können, in Verindung zu einem mit ssh verbundenen git Server, dessen working tree ausgecheckt ist und auf dem Server ebenso editiert wird (non-bare).

---

Nicht immer ist die neue git "push-to-deploy" Funktion praktikabel, insbesondere nicht, wenn am Server der ausgecheckte working tree nicht read-only ist, sondern auch dort aktiv editiert wird. In diesem Fall kann "push-to-deploy" zu Problemen führen, nämlich dann, wenn Server-seitig Änderungen noch nicht commited wurden, aber ein Client bereits push-t. "push-to-deploy" ist eher geeignet für z.B. git non-bare readlony Webcontent auf Webservern.

---

Wenn man zusätzliche Development Maschinen als Client mit dem git Server verbinden mag, ist es vermutlich besser, serverseitig ein bestehendes non-bare repostiory in ein bare repository zu übertragen, und daraus dann ein "zweites" non-bare repository abzuleiten (wiederum auf dem Server), mit ausgechecktem working tree.
"git clone --bare quelle1 ziel.git"
danach kann man "ziel.git" - Server zu Server - clonen:
"git clone ziel.git quelle2"
"quelle1" ist dann obsolet (als Backup ggf.), "quelle2" ist dann verwendbar.
In "quelle2" zeigt z.B. "git ls-remote" die Verbindung zum neuen bare repository. Dieses server-seitige bare repository kann man dann z.B. über ssh von den Development Maschinen aus erreichen. Anlegen z.B. - vom Server zum Client - auf dem Client, mit "git clone myuserid@myservername:/serverpath/ziel.git". Anmerkung: Die bare Eigenschaft eines git repositories erkennt man üblicherweise bereits am Foldername, der auf .git endet. Darin gibt es dann keinen working tree und keinen .git subfolder wie bei den non-bare repositories üblich.

To solve the lagging issue, in obs go to Video Capture source -> Properties -> Video Format (third Option in the list) -> de-select YUYV 4:2:2 -> select Motion-JPEG instead (e.g.)

One possible solution:
Mount explicitly by command.
E.g.
$ sudo mount -t ntfs /dev/sda2 /mnt/xyz01
or
$ sudo mount -t ntfs3 /dev/sda2 /mnt/xyz01

Set temperature:
$ redshift -O 1000

Reset:
$ redshift -x

Script in Autostart einhängen, für automatische, explizite Festlegung nach Login:

#!/bin/bash
sleep 3
redshift -x
redshift -O 1400

Anmerkung: Das Programm "redshift" in Autostart nicht aktivieren.

In newer releases Manjaro Xfce is booting with an animated splash screen (animation with three white dots on a black screen, "plymouth splash"), not displaying the textual boot log any more. When booting gets stuck, this may lead to missing informations. To prevent this, and return to more classical booting style, the "bootsplash-manager" can be used. there, switch to "boot log" profile.

It probably maintains /etc/default/grub file, entry GRUB_CMDLINE_LINUX_DEFAULT where the tag "quit" gets removed, and "splash" remains unchanged. "nomodeset" seems not to be added.

1. Prüfen, ob User bereits in autologin Gruppe:
$ getent group autologin autologin:x:1000:myusername

2. Prüfen der Datei "/etc/pam.d/lightdm-autologin".
Nötig ist ein Eintrag der Form:
auth [success=1 default=ignore] pam_succeed_if.so user ingroup autologin

3. "/etc/lightdm/lightdm.conf" benötigt einen Eintrag der Art "autologin-user=myusername"

The warning message
PostgreSQL collation version mismatch
The database was created using collation version 2.36, but the operating system provides version 2.37. might be caused by updating the host operating system's glibc, which is responsible for collation implementations, and which the database is using in turn. When collation versions between host and database differ, this may lead to the message above. Typically it doesn't occur in stable versions of host operation systems, but in test versions.

To adjust settings at "Logitech G203 LightSync" (with 3 LEDs) device, "piper" can be used. But the Manjaro package "piper" and its prerequisite "ratbag" / "ratbagd" are not yet identifing this specific hardware model.

To work-around this issue, remove "piper" and "ratbag" packages, and install "piper-git" and "ratbag-git" packages via AUR. Then a "$ killall ratbagd" to stop the old service should suffice, then restart "piper" (it starts the new "ratbagd" implicitly), and then you can adjust the LEDs and other things.

Please note: Currently is only one LED color for all three LEDs simultaneously possible, not three different colors.

Q: When I try out a Scala 3 macro, the inline definition of the macro itself with the splicing, and the function which e.g. is using quotations, when I compile this in sbt I get printed all macro println's to the console at compile-time, as it is expected.
However, when I switch to IntelliJ with the Scala plugin, bsp and bloop compile server installed, those macro println's are missing when I compile, and even I looked into any log I could open, but could not find those macro println's. Any idea how I could see those printlns in Intellij? I am using BSP, Bloop, Scala Compile Server. I slightly suspect that compile server output does not reach Intellij build console.

---

A: Instead of using the hidden IntelliJ BSP Bloop compile server, in an IntelliJ console tool window, run "sbt ~compile" (while being pwd'ed in the correct project path).
IntelliJ will use this as the build server (since it won't start two at the same time - sytem-wide) and you will see the macro compile-time println log entries in this sbt console printout.

Alt + Mouse Wheel Zoom (Manjaro Xfce) can be accomplished by calling "xfce4-settings-editor", selecting channel "xfwm4", then enabling property "zoom_desktop".

e.g. 1 minute waiting time before launch instead of 2 seconds, as it has been before the Manjaro update.
Interim solution:
add "xdg-desktop-portal-gnome" software package, afterwards, remove it.
Reboot.

Hardware Info zur CPU, mit Graphik (CPUs, Cores)

Software package: lstopo

• in the keyboard settings "xfce4-keyboard-settings", assign xfce4-popup-whiskermenu --pointer
  to Super Left key (windows key)
• if then unintentionally a desktop context menu gets opened ("create launcher, create url link, create folder, create document, ..." etc.) then the reason could be that there is one superfluous setting active.
  Goto " session and startup", open "Application Autostart" tab, then deactivate the xcape entry: xcape -e 'Super_L=Alt_L|F1'

1. first check the vscode setting "terminal.external.linuxExec"
2. the official release directly from Microsoft has fixed this issue already. so deinstalling the distribution package, and instead using the Microsoft download, should work (if you want pay the "price").
3. as a work-around until this bug is fixed in the distribution package, instead of external terminal, the internal terminal panel works. execute command ( Ctrl + Shift + p ) "Toggle Terminal ": ( Ctrl + Shift + ´ ) then a internal terminal panel opens. if more terminals are needed, then: right click in the terminal area, "New terminal".

Teilweise sind Bereiche der Anwendung stark regelbasiert und lassen sich nur mehr recht als schlecht mit prozeduralen Programmiersprachen realisieren. Hier können Subsysteme zum Einsatz kommen, welche in Prolog implementiert sind.

Typische fachliche Bereiche für Logik Engines sind z.B. Berechtigungen, Optimierungen, Compliance.

Logik-Berechnungen sind generell "costly", lassen sich aber auch cachen, damit die Performance nicht darunter leidet. swi Prolog ist eine der vielen möglichen Implementierungen einer Prolog Engine.

hashcat:

"hashcat -I" starten, uim zu sehen, welche GPU devices verwendet werden. Wenn es nur 1 Device ist, mit Type = CPU, wird die GPU (IGP) nicht verwendet.

"hashcat -b" starten, um die Performance der APU zu untersuchen.
Es tritt der Fehler auf: "* Device #1: Kernel /usr/share/hashcat/OpenCL/shared.cl build failed".

Hashcat für APU Performance Messung Beispiel Ubuntu:

$ hashcat -b
hashcat (v6.2.6) starting in benchmark mode

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

Depending on your Console or IDE application, ANSI colors might be displayed differently. Here is a small Scala test frame helping identify ANSI color codes by example printout ("rainbowing"). Repository on GitHub

• 1. "inxi -N" liefert die Adapter Kennung. Es ist erforderlich, den Linux Kernel auf 5.16.14. upzudaten.
• 2. Das MT7921k Modell von Mediatek hat die Besonderheit, dass teilweise ein 60 Sekunden Power Shutdown (PC ganz aus, stromlos, für 60 Sekunden) nötig ist, um die Karte aktivierbar zu machen.

Diese obigen Punkte können Abhilfe schaffen, wenn WLAN Verbindungen trotz vorhandener Hardware im System nicht angezeigt werden.

draw.io desktop e.g. version 22.0.3 - but probably other versions too - have problems with file save and reload later, sometimes a dialog appears mentioning "unsaved changes", and the user has to decide how to proceed. The message appears too often in my eyes. A work-around is: Goto menu "Extras" (in some themes its called "Settings" instead), then "Drafts ...", then enter "0" (zero) in the field "Draft save interval [sec] (0 to disable):".
That fixes the problem as far as I can observe.

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.
18 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
