I'm doing PHP for the first time in years. I needed a function that returns the date of last week's Monday. Turns out PHP has a funky date querying language. I can just do: $today->modify('monday last week'). Makes me happy.

[It has been (1) days since the last time that I needed strtotime]

Don't know how to do this without PHP, so I actually use it on the shell inline between a bunch of Bash. I assume that's the same function with new syntactic sugar

Today, I am revising Portuguese grammar and so I've mostly been exploring the things I can remember well and those that I can't. Portuguese has a lot of verb forms that I need to get right. But it also has really interesting constructions like "ir ter com" which literally means "to go to have with" but is an idiomatic way of saying "to meet up" (with someone) and I keep remembering and forgetting it.

What do you use to revise this? Did you download or make an Anki deck?

Reading up on the history of information management, and the real killer app for paper was double-entry bookkeeping, which made Venice rich and contributed to starting the Renaissance.

It was the killer app for personal computers as well. From Lotus123 to my family's small business in a tiny country that could only afford a computer in 92 for the business.

I found out today that the location header of an HTTP redirect can be a tel:+ URI and phone's will actually ask you whether you want to call that number.

Did you know that you can assign arbitrary programs (protocol handlers) to arbitrary protocols?

I have started exploring Seneca/stoicism again. Prompted partly by a recent submission here, partly by personal reasons. Instead of consuming other peoples interpretation of stoicism I decided to go as close to the source as feasible for me. I have read Letters from a stoic a number of times before and my copy is filled with highlights, but this time I think I will try to limit myself to one or two letters a day and…

I hope you get more out of it than I did. I don't recall which of Seneca's work I read several years ago, but to me it was ... meh?

Some of the stuff I strongly agreed with, but I didn't derive value because I already had the mindset. Other stuff I disagreed with, and the book didn't really convince me. Then there was the stuff in between.

Overall, it felt like something you or I could have written - I didn't see something insightful that enlightened me.

Not to take away from your essay, which I thoroughly agree with :-)

There does not yet exist a (strong) chess engine that tries to force its opponent to win against it (who is assumed to have the same objective)

You might enjoy hatetris (tetris, not chess, but it optimises against you in a way that felt similar)

I found out my crimson-bellied conure is laying an egg today! She's nesting in some towels now, chirping away while she works on laying it. Having an egg is relatively hard on parrots. I've given her lots of food and warmth to prepare. She is comically hungry -- she's usually not such a big eater, but she's happy today to be scarfing down her apple slices, fruit pellets, and safflower seeds. She usually sleeps at the…

Good luck to both of you!
