Flashcard of the week

This is a flashcard I recently made even though I think it's too easy to make a card out of.

What's another way to write the integral ∫ kx dx?

The reason I made a flashcard for it is that even though I think it's too easy I keep forgetting it when I need to know it!

The hint that should make it more clear is that the integral is sorta-kinda a sum. If we have (kx + ky) then we can write it as k(x + y), and by analogy ∫ kx dx is

Forecasting 2026 (premium newsletter)

I have made forecasts on almost all ACX 2026 prediction contest questions. On some I spent more time than I should have. Once I'm done with that, I'll summarise my notes in the premium newsletter. Hopefully within the next week or two.

Additionally, it will contain a brief introduction to multiple-criteria shortest path finding to better understand a board game my children received on Christmas. (The personal notes section also contains some stuff about migrating my son from NetBSD to FreeBSD, and reinstalling the FreeBSD home server which has had a broken ZFS mirror since summer.)

You might not think any of the above is interesting, but you'd still like to support the blog. You can do so for $4 per month, cancelable any time with no questions asked. To upgrade, click the subscription link at the top of this newsletter and fill in your email again.

If you do, you'll also get access to the most recent premium newsletter about optimising automated test execution, text adventures, storytelling, and links to three small games I've enjoyed recently. Oh, and that mysterious image illustrating compass sighting. Right, and the full archive of the other 8 premium newsletters, too.

(I have increased the price for new subscribers because (a) the archive of premium newsletters has grown, and (b) I have been told people want to support the blog with more than $2 per month. But I also don't want to price anyone out – if you cannot pay for the premium subscription for any reason, reach out to me and we'll come to an agreement.)
