# This script runs ps_util.cpu_percent(interval=0.5) for each process to calc
# the cpu utilization percentage 
# It does so concurrently as otherwise each calls sleeps 0.5 secs to sample the data
# to run it faster use more threads in ThreadPoolExecutor(max_worker=x or
# reduce the interval for cpu_percent(interval=x
# To make readings more 'accurate' use a longer interval e.g. 1.0 for 1s.

Building Armbian using Ubuntu (jammy) in a systemd-nspawn container

These are some steps for building armbian using Ubuntu (jammy) in a systemd-nspawn container. This is an alternative for building armbian from a Linux system (as like docker containers).

However this method requires the PREFER_DOCKER=no build flag as docker engines cannot be run within a systemd-nspawn container.

• install
• Start the systemd-nspawn container
• Building Armbian in systemd-nspawn container

# This make file for stm32duino core and Marlin 2.0 is possibly *dangerous*
# i.e. it compiles the sources (in src, Marlin, Arduino_Core_STM32, variants and CMSIS_5) directory 
# and overwrite all the stuff in $(out_dir)
# $(out_dir) is the binary directory where the object files are dumped there
#
# make clean *deletes* the *$(out_dir)* (coded here as build )
