#NowSpinning Bruch’s Second Violin Concerto, a work I do not know. Fortunately Perlman seems to know it rather well! How interesting to hear it’s first movement almost pick up where the First left off. A bit of recycling isn’t necessarily a bad thing.

A filter that flew to the moon
Rudolf Kálmán's 1960 filter was met with scepticism, until Stanley Schmidt at NASA Ames saw how to use it for navigation.
An extended version guided Apollo to the Moon.

It's been 12 years since I last updated Quick Resizer, a Mac App that... quickly resizes images.
I built it because I hated waiting 10s or so to launch Photoshop just to scale an image for my blog.
I let Claude fix 3 bugs and port it to Swift (under my guidance), and it's now hit 2.0, and works better than it ever did before (and waaaay faster on modern Apple Silicon). Plus it still runs on Intel, at least macOS 13+!
It's still $0.99 as it always was: apps.apple.com/us/app/quick-…
And now I can again stop launching Photoshop's monstrous husk of an app just to scale down photos for my blog.

I'm doing a course based on my Cultures of Programming book! A perfect excuse to also record the material for anyone who prefers listening over reading.

If you get a perfect working iPhone 6, log into it, and go to the App Store, you can't install apps because Apple has discontinued support for all iOS versions the iPhone 6 uses.
200+ million iPhone 6 phones were produced. All now banned from apps.
Think about that.

This is how we vote in Israel.
No machines.
Just place a paper slip in an envelope.
No need to register.
Every citizen 18+ is automatically assigned a polling place , by their address.
Show your ID , step behind the blue cardboard, and participate in democracy.

Purdue University's IDEAS Lab built an autonomous drone that tracks runners through dense forests completely without GPS or cloud networks.
By running 3D LiDAR mapping and obstacle-avoidance AI entirely on-chip, it can weave under tree canopies and predict target movement through blind spots in real time.
Massive implications for next-gen search & rescue and edge AI.
