# The command finds the most recent tag that is reachable from a commit.
# If the tag points to the commit, then only the tag is shown.
# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object 
# and the abbreviated object name of the most recent commit.
git describe

# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
git describe --abbrev=0

Step 1: Compiling or Downloading the toolchain

Step 1.a: If you choose to download a pre-compiled toolchain (only for Linux x86-64)

• Go to https://toolchains.bootlin.com
• Select arch: armv6-eabihf
• Select libc: glibc
• Download bleeding-edge
• Uncompress it (for example to /opt)
• Add the bin/directory of the toolchain to $PATH
• In my case: export PATH=$PATH:/opt/armv6-eabihf--glibc--bleeding-edge-2020.08-1

ABOUT

about:config settings to harden the Firefox browser. Privacy and performance enhancements.
To change these settings type 'about:config' in the url bar. Then search the setting you would like to change and modify the value. Some settings may break certain websites from functioning and rendering normally. Some settings may also make firefox unstable.

I am not liable for any damages/loss of data.

Not all these changes are necessary and will be dependent upon your usage and hardware. Do some research on settings if you don't understand what they do. These settings are best combined with your standard privacy extensions (HTTPS Everywhere, NoScript/Request Policy, uBlock origin, agent spoofing, Privacy Badger etc), and all plugins set to "Ask To Activate".
