Raspberry Pi | how to disable swapping

If you wan’t to disable swapping on your raspberry pi to prevent fast weardown of you SD card or even if you are using a SSD to boot on via USB it can reduce your disks lifespan if you have swapping turned on and it’s default on.

Here is how to completely disable swapping on Raspberry Pi (raspberian)

sudo dphys-swapfile uninstall
sudo update-rc.d dphys-swapfile remove
apt purge dphys-swapfile

This is tested on my Raspberry Pi 3 with Raspberian 9 (Debian 9 based)

CS:GO | Linux | Playing against my 10 year old kid and losing

I have tested Steam on my old Lenovo T450 laptop that is my secondary machine, it’s running Linux Mint 19 Cinnamon Edition and is working great with Steam. I’m quite surprised that it was fast enough to Play CS:GO and in the same time being recording a full desktop session, but it worked out just fine. My hardware is Core 5i CPU, 8 GB RAM, Intel HD 5500 Grapichs card, 128 GB SSD harddisk. I used KaZam to record with, it came with Linux Mint.

Jenkins – change default locale to english

To my surprise today Jenkins startede to speak to me, that was pretty scary. To change that behaviour then you have to install a locale pluging and set the default language.

INSTALL THE LOCALE PLUGIN

Go to -> Manage Jenkins -> Manage Plugins -> Click on Availables -> Check the “Locale plugin”

Just choose the option “Download now and install after restart”

Go to the plugin manager again and check if it is enabled.

SET THE LOCALE TO ENGLISH

Go to -> Manage Jenkins -> Configure System -> Locale -> set it to en

Check the option Ignore browser preferences otherwise your browser language would set it to your locale and it won’t work.
