Build a HTML5 “Helix Jump” prototype with Three.js and TypeScript – Step 4: scoring, animated CSS background and platforms fading away

In the fourth step of the Helix Jump HTML5 prototype with Three.js and TypeScript, I added a clean CSS-based score display, a subtle animated background using only CSS, and made destroyed platforms fade out and fly away with GSAP. These visual touches make the game feel more alive, and as always, you get the full line-by-line commented source code for free.

Unionize or die

Tech workers have long resisted the suggestion that we should be organized into unions. The topic is consistently met with a cold reception by tech workers when it is raised, and no big tech workforce is meaningfully organized. This is a fatal mistake – and I don’t mean “fatal” in the figurative sense. Tech workers, it’s time for you to unionize, and strike, or you and your loved ones are literally going to die.

In this article I will justify this statement and show that it is clearly not hyperbolic. I will explain exactly what you need to do, and how organized labor can and will save your...

The British Airways position on various border disputes

My spouse and I are on vacation in Japan, spending half our time seeing the sights and the other half working remotely and enjoying the experience of living in a different place for a while. To get here, we flew on British Airways from London to Tokyo, and I entertained myself on the long flight by browsing the interactive flight map on the back of my neighbor’s seat and trying to figure out how the poor developer who implemented this map solved the thorny problems that displaying a world map implies.

I began my survey by poking through the whole interface of this little in-seat entertainment system1 to...

2025-05-05

On Sunday, 2025-05-11 there will be scheduled maintenance of the suckless servers. It's estimated this will take about 2 hours from about 10:00 to 12:00 UTC.

The mailinglist, website and source-code repositories will have some downtime.

Update: the maintenance was finished at 2025-05-11 13:00 UTC. There was a small issue with storage space, hence the 1h delay for fixing it.
