Migrating to the EU
For various reasons, I have decided to move as many services and subscriptions as possible from non-EU countries to the EU or to switch to European service providers. The reasons for this are the current global political situation and improved data protection. I don’t want to go into the first point any further for…

Bored of eating your own dogfood? Try smelling your own farts
I called a large company the other day. Did I know the information I wanted could be found on their website? And was I aware that I could manage my account online? And would I like to receive a link to chat with their AI assistant via WhatsApp? Naturally, call volumes were higher than expected. I can only assume that…

A case against currying
Curried functions are probably one of the first new things you come across if you go from an imperative language to a functional language.

Chest Fridge (2009)
Chest fridge Using vertical doors in refrigeration devices is an act against the Nature of Cold Air.

Hide macOS Tahoe's Menu Icons
I really dislike Apple’s choice to clutter macOS Tahoe’s menus with icons. It makes menus hard to scan, and a bunch of the icons Apple has chosen make no sense and are inconsistent between system applications. Steve Troughton-Smith is my hero for finding a Terminal command to disable them: Here’s one for the…
