I make video players for NRK for a living, and I live to ride bikes in the forest. I can juggle.
Wrote some words on how to live a moderately happy life with (too) many dependencies in javascript, docker and github actions, in the shadow of the resurgence of the Shai-hulud worm

I've been an AI curmudgeon for a long time, I am getting old after all, but the chrome devtools mcp server (github.com/ChromeDevToo...) is very promising for analysing and working with performance related stuff. And probably more.

I'm gonna give a talk at @javazone.bsky.social on web and browser performance this year. Happy, exceited and scared shitless at the same time.
Oh, and I'm gonna throw some shade on React and friends, I have learnt from the master @infrequently.org

I was today days old when I learned about the `touch-action` css property and the `pointercancel event`, fixing an android bug. Turns out chrome for android is more picky about these things than mobile safari.

The touch-action CSS property sets how an element's region can be manipulated by a touchscreen user (for example, by zooming features built into the browser).

Super cool, actually to discover all these new things. But then again not so cool :-(

Todays random internet curiosa: there is a mountain, which is also an active volcano, called Mount Terror. As it is in Antarctica I can only imagine it's aptly named even though it is named after a ship and sadly not a camping trip gone properly off the rails.
