We as Ontarians really should be a lot more mad about laws that allow the premier to ignore laws because he feels like it.

Ford to declare Billy Bishop Airport a ‘special economic zone’ to allow jets

Use of new legislation passed last year allows province to circumvent normal permitting processes and municipal laws

The notion of a broken clock being sometimes right is based on a gross misunderstanding of what information is.

A clock that always shows the same time is never right, even in the moments of the day when the time happens to be what it shows, because you don't gain any information about what time it is by looking at the clock.

This reasoning also applies to chatbots. If you can't tell whether what you have been given is useful information unless you alreay know the information, then you haven't been given useful information.

It looks like the ⍼ saga has finally ended!

The unicode character '⍼' was a mystery first noticed in 2022: https://ionathan.ch/2022/04/09/angzarr.html. It's in the Unicode standard as a mathematical symbol. But no one could find any examples of it having been used, and no one knew what it represented. It was like the only record of an extinct species, fossilized in the Unicode standard.

But now someone has found the document it originally came from! It represents the angle 'Azimuth', and the symbol probably comes from the path light takes through a sextant. https://ionathan.ch/2026/02/16/angzarr.html

(@johncarlosbaez might appreciate this symbol!)

Check out this insane curl by #Canada's #JonThurston against #Norway

If you don't know #curling the goal is to get your stones closer to the center than your opponent. The strategy is to knock your opponent's stones out, avoiding (or knocking closer) your own stones

His precision is stunning

There are no sweepers in #wheelchair curling, no adjustments to the shot after it is made. Instead his teammates hold his wheelchair steady

Happy #BlackHistoryMonth !

Feb 19:

Q: Why is so much Black music about violence and misogyny? I'm not racist, but is Black culture just more violent?

A: Racism. Rap, trap, and drill, are only the most popular genres of Black music listened to *by white people.*

I can't stop thinking about the LLM-generated compiler that passes all the unit tests but emits inner loops that benchmark over 150,000x slower than a gcc debug build. I couldn't possibly have intentionally come up with such a funny demonstration of the point of genuine expertise https://harshanu.space/en/tech/ccc-vs-gcc/

When I left SpaceX I lost access to this data on my home board. It made me super sad. So I had a friend help create a new board, not just limited to SpaceX but all launches around the world! This is still a work in progress, but you can use it now if you want to see the latest launches!

Hit up https://vestaboard.projecttomorrow.com/ add your board, select the format you want and BAM! Earth departures auto updated on your board!

@b0rk in my experience, as someone who is often a "senior engineer," one of the most effective things I can _personally_ do to combat this and encourage a learning attitude is to be quick to say "I don't know," and quick to admit when I'm wrong.

People really do pick up on behaviors like this from "senior" types (or their absence!).

I say this mostly in case anyone else in a similar position reads this thread and goes "but what could I possibly do to shift the culture in this direction"
