[Git] Error on Windows using VSCode Dev Container

After connecting to a local dev container using Visual Studio Code and trying to clone a private project from Github I got the following error:

Cloning into 'myProject'...
warning: url has no scheme: helperselector
fatal: credential url cannot be parsed: helperselector

The only way I could remove this error was deleting the helperselector settings. So open the git config with:

git config --edit --global

and remove the the helperselector block (the first two lines). You will now get asked again for your credentials when cloning a project.

[Mint] Keyboard not recognized after suspend

In January 2020 I bought a Sharkoon PureWriter Keyboard and since then I had the problem that the keyboard got not recognized after my PC (which runs on Linux Mint) was coming back from suspend mode. Back then I couldn’t find a solution and was just hoping that a newer kernel release will fix this problem in the future. But it did not. So today I was searching again and stumbled again across this post, but now I noticed the new answer from April this year. And it finally solved it!

https://askubuntu.com/questions/1044988/usb-ports-not-working-after-resume-from-sleep-on-ubuntu-18-04

First check with usbreset for the device name and then create the script under the following path:

sudo micro /lib/systemd/system-sleep/reset-keyboard 
#!/bin/sh

case $1 in
  post)
    usbreset "USB-HID Keyboard"
    ;;
esac

And as a last step we make it executable:

sudo chmod +x /lib/systemd/system-sleep/reset-keyboard

[Terminal] Using rsync with –backup and –delete together

I’m using rsync to create backups from my NAS to an external HDD. The command looks like this:

rsync -azP --delete --exclude=/.zfs -b --backup-dir=Backup /mnt/nfs/photos/ /media/nocin/externalBackup/photos/ 
rsync parameterdescription
-a –archiveThis is equivalent to -rlptgoD. It is a quick way of saying you want recursion and
want to preserve almost everything.
-z –compressWith this option, rsync compresses the file data as it is sent to the destination machine, which reduces the amount of data being transmitted
-PThe -P option is equivalent to –partial –progress. Its purpose is to make it much easier to specify these two options for a long transfer that may be interrupted.
–deleteThis tells rsync to delete extraneous files from the receiving side (ones that aren’t on the sending side)
–excludeexclude files matching PATTERN
-b –backup-dirWith this option preexisting destination files are renamed with a ~ extension as each file is transferred. You can control where the backup file goes and what (if any) suffix gets appended using the –backup-dir and –suffix options.

But somehow it always created the Backup folder recursively again inside the Backup folder. So the first run created the /Backup folder, after the second run I’ve got /Backup/Backup, after the third run /Backup/Backup/Backup and so on..

The solution was to exclude the Backup directory using the --exclude command.

rsync -azP --delete --exclude=/.zfs --exclude=Backup -b --backup-dir=Backup /mnt/nfs/photos/ /media/nocin/externalBackup/photos/ 

I found a good explanation for this behaviour here: https://www.jveweb.net/en/archives/2011/02/using-rsync-and-cron-to-automate-incremental-backups.html

“If we are storing backups in the destination folder, or in a directory inside of the destination folder, the --delete parameter is going to delete old backups, as they are not in the source folder. Or attempt to as in the following situation:

Say, we already have a folder called backup inside of the destination directory, and we use rsync again, using --backup-dir=backup one more time. As rsync is going to attempt to delete every file and folder that is not in the source directory, it would backup the backup folder, which would create a backup folder inside our already existing backup folder, and then it would attempt to delete the backup folder and fail because it is using it to backup files.”

[Mint] Install PyWal on Linux Mint 20.1 Cinnamon

“Pywal is a tool that generates a color palette from the dominant colors in an image. It then applies the colors system-wide and on-the-fly in all of your favorite programs.”

https://github.com/dylanaraps/pywal/wiki/Installation

pip3 install pywal

I’m using Variety to change my wallpaper every day automatically. To always get the right colors in my terminal I added some lines in my .zshrc that will always grab the current wallpaper and pass it to PyWal. I’m sure a bash pro would do this in just one line… 🙂

#---PyWal---#
# load previous theme
(cat ~/.cache/wal/sequences &)
# get picture path
picturepath=$(gsettings get org.gnome.desktop.background picture-uri) 
# remove prefix & suffix
prefix="'file://" 
suffix="'"
picturepath=${picturepath#"$prefix"} 
picturepath=${picturepath%"$suffix"}
# set colors
wal -n -q -i "$picturepath"
#---PyWal End---#

There are many plugins/tools you can combine with PyWal:
