Remove superfluous apps from Lenovo Yoga Smart Tab

June 5, 2020 - Reading time: 2 minutes

I tried to deactivate several apps which I did not use on my Lenovo Yoga Smart Tab. Unfortunately the Play Store displayed updates for them soon after and they were activated again by some kind of magic.

To remove the apps I do not want on my device I connected via

adb shell

and uninstalled them by running the following commands:

pm uninstall -k --user 0 com.android.chrome
pm uninstall -k --user 0 com.google.android.calendar
pm uninstall -k --user 0 com.microsoft.office.outlook
pm uninstall -k --user 0 com.google.android.youtube
pm uninstall -k --user 0 com.google.android.apps.photos
pm uninstall -k --user 0 com.google.android.apps.tachyon # Google Duo
pm uninstall -k --user 0 com.google.android.apps.magazines
pm uninstall -k --user 0 com.google.android.googlequicksearchbox
pm uninstall -k --user 0 com.google.android.apps.googleassistant
pm uninstall -k --user 0 com.lenovo.screenassistant
pm uninstall -k --user 0 com.google.android.apps.wellbeing        # Digital Wellbeing
pm uninstall -k --user 0 com.google.android.apps.nbu.files        # Files
pm uninstall -k --user 0 com.google.android.gm                # GMail
pm uninstall -k --user 0 com.google.android.apps.docs            # Google Drive

Fixing failure of software upload to µController

December 5, 2019 - Reading time: ~1 minute

If uploading software from the Arduino IDE or the commandline via avrdude to a microcontroller like an Arduino or an ESP8266 fails due to missing access rights ("Permission denied"), what helps is either

sudo chmod a+rw /dev/ttyUSB0

or adding the user to the group "dialout":

sudo usermod -a -G dialout theuser

Repairing the file system of Debian after hard shutdown

Sometimes after a hard shutdown the file system of my laptop is corrupted and Debian starts in maintenance mode.

What helps is repairing the file system using the command

fsck -y /dev/sda1
