Get Brackets working on Ubuntu >=18.04 and Mint 19.x

Posted 05-23-2019 at 04:03 AM by hydrurga

The problem
Brackets, the useful web development editor and environment, can be downloaded as a deb archive from http://brackets.io/.

To understand partitions, it is important to remember that storage devices divide up their space into sectors which are traditionally 512 bytes in length. However, since 2010, most large hard disks (called Advanced Format (AF)) now have physical...
