Posted on April 23, 2020 Leave a Comment
I run a few PHP based applications which require background jobs, and I use the usual crond via crontab to run the jobs.

A Golang program to dump serial data into CSV file
Posted on March 24, 2020 Leave a Comment
A unique situation in which I wanted to dump the memory of a program running on a microcontroller – the program can send data through serial port, but for it to make sense for the programmer it has to be dumped in a readable format.
