Keyboard shortcuts for GNU Readline
Most command line programs that offer line editing -- like bash, Python, GDB, psql, sqlite and more -- do so using GNU readline. Readline's a powerful library that grants history, completion, movement and editing to programs that use it --- and a stable and consistent set of keyboard shortcuts. Shame, then, that even…

The “No Code” Delusion
Increasingly popular in the last couple of years, I think 2020 is going to be the year of “no code”: the movement that say you can write business logic and even entire applications without having the training of a software developer. I empathise with people doing this, and I think some of the “no code” tools are…
