I believe teachers don't explore reflections in circles because they don't understand the geometry behind it, which is based upon an altitude to the hypotenuse in a right triangle, tangents to circles, geometric means OB*OC=Radius^2. Simple and beautiful

You can filter any Mastodon account's public posts by hashtag using the following website address:

(mastodon profile's web address)/tagged/(hashtag without the #)

So, for example, to see all my public posts with the hashtag "Mastodon" the address would be:

mstdn.social/@feditips/tagged/…

:rss: As many have pointed out in comments, you can also add .rss to the end of the address to create an RSS feed.

' Often, when we give a blank map of the surrounding areas to Inuit who are helping us [they] have no problem recognizing and identifying features on the map, going only from their recollections of the land and what their families have described to them in words or in songs — without otherwise having used maps. They’ll even correct you, explaining something like, “there should be a lake there, but it’s not on your map.” '

@pluralistic pointed to a wonderful post by Jo Walton, which included the following (re how SF fans read SF):

"There are lots of forms of what I call incluing, scattering pieces of information seamlessly through the text to add up to a big picture. The reader has to remember them and connect them together. This is one of the things some people complain about as “too much hard work” and which I think is a high form of fun."

Yes. Yesyesyes. A perfect encapsulation.

On January 10, 2014 in the Spanish city of Burgos, the local government and a cabal of real estate developers were pushing ahead with a project to gentrify a working class neighborhood by constructing a fancy new boulevard. The neighbors of Gamonal held a protest and the police attacked, sparking four consecutive nights of rioting in which people destroyed banks and construction equipment, and fought with police.

Afterwards, they continued holding protests demanding the unconditional release of those arrested, and they organized blockades to prevent construction. The mayor initially announced that the project would continue unabated. Solidarity protests were organized in dozens of other cities across the country, leading to riots/clashes in Madrid, Barcelona, Zaragoza, and the colony of Melilla. In Barcelona, multiple banks were smashed, Town Hall was attacked, and a central police station was attacked, forcing police to temporarily retreat. The gentrification project was subsequently cancelled.

I'm thinking about getting a "new" used car. Unfortunately, tests of driver assistance / "self driving" systems don't seem to be any better than they were three years ago when I wrote danluu.com/car-safety/.

No one's doing anything resembling what a programmer would consider serious benchmarking and it doesn't look like anyone is going to either even though driver assistance / ADAS systems are becoming a more important part of safety over time.

in reply to Dan Luu

so it's now nearly impossible for the general public to make judgments about automotive safety except in cases where the company repeatedly ships extremely shoddy software, e.g., Tesla with mastodon.social/@danluu/109514…, twitter.com/kenklippenstein/st…, etc., but Uber was the only other company putting something so obviously bad on the roads, so this doesn't give you much information.

FWIW, I'd say that BMW has the best methodology I know of among cars you can buy (I updated the post to reflect that), but

in reply to Dan Luu

every company I know of that's selling a "shipping" car has a methodology that you'd consider "move fast and break things" if they were a software company; the spectrum runs from "nearly completely untested, relies heavily on vendor's components working when connected (essentially never verified) while pushing vendors to add unsafe features to reduce cost or increase velocity" to "moves quickly and cuts corners that create significant risk".

Just for example, a semi-typical story is

For those who follow me because of my work on AccessKit, this has nothing to do with that, except that filling the position may allow me to spend more time on AccessKit.

This evening I pushed a #Prosody community module that acts as a #UnifiedPush server. It allows apps on your phone to receive push notifications, using #XMPP as the delivery channel instead of Google's proprietary FCM or regular polling.

It uses a protocol devised and implemented by @daniel and all credit goes to him for this idea and first implementations.

It's all experimental stuff, but I'm already using it to get realtime notifications in #Fedilab 🙂

In exciting async news: the stabilization of `std::pin::pin!` has been accepted, and will be coming to stable on #Rust on 1.68.0!

This will enable "stack pinning" entirely from safe Rust, replacing many of the uses for `Box::pin`, the unsafe `Pin::new_unchecked`, and external crates such as `pin-utils`!
