Adrian has been blogging about software development since 2004.
"Being A Developer After 40" – received more than half a million views and made the front page of Hacker News. It has been shared over six thousand times on social media, was reprinted in Hacker Bits, and has been translated by volunteers to Russian, Hungarian, Czech, Portuguese, Persian, Vietnamese, and Romanian.
Adrian has also explored screenwriting a bit, mostly using the Fountain format, through the excellent Better Fountain extension for Visual Studio Code. The result is "Una Habitación con Vista al Mar" (in Spanish, also as pdf and fountain) written in 2016.
