This Arduino Nano R4-controlled hourglass simulates sand with LEDs

from Arduino Blog [alt+shift+b] in technology

Feedback about the redesigned IDE is overwhelmingly negative due to bugs, poor UX & model support, and eating through Gemini token quotas. Also: a clue that Antigravity’s own devs use other tools for their work?

Writing code for a computer is hard enough. You take something big and fuzzy, some large vague business outcome you want to achive. Then you break it down recursively and think about all the cases until you have clear logical statements a computer can follow.

When Google killed Google Reader, the bloggosphere took a severe hit and the content quality went down because there weren't enough readers to justify the effort it takes to maintain a high quality blog.

What's left is a decaying wasteland of blogs, most abandoned, a lot are now SEO spam, and 99% are not worth reading. BoredReading is a way to read the remaining great blogs that survived the ice age.
