Just got a good(-enough) news notification on my phone (and yes I do like staying a littttle plugged in high level, deeper diving when really curious). sigh of relief

Some days, it’s too many important & awful stories, though.

Imagine an app that gets copies of all your notifications, analyzes their sentiment locally, and pushes good news stories from the day/month accordingly. (Or more doably, push good news notifications based on how many awful stories major new publishers have written that day.)

Maybe more effective than just following a positive-news-only source, since the biggest-impact good news could be saved up for the darkest days.

Just Post 🧘‍♂️

Thanks founder + community!

“When I grade students’ assignments, I sometimes see answers like this:

Utilizing Euler angles for rotation representation could have the following possible downsides:

• Gimbal lock: In certain positions, orientations can reach a singularity, which prevents them from continuously rotating without a sudden change in the coordinate values.
• Numeric instability: Using Euler angles could cause numeric computations to be less precise, which can add up and produce inaccuracies if used often.
• Non-unique coordinates: Another downside of Euler angles is that some rotations do not have a unique representation in Euler angles, particularly at singularities.

The downsides of Euler angles make them difficult to utilize in robotics. It’s important to note that very few implementations employ Euler angles for robotics. Instead, one could use rotation matrices or quaternions to facilitate more efficient rotation representation.

[Not a student’s real answer, but my handmade synthesis of the style and content of many answers]

You only have to read one or two of these answers to know exactly what’s up: the students just copy-pasted the output from a large language model, most likely ChatGPT. They are invariably verbose, interminably waffly, and insipidly fixated on the bullet-points-with-bold style. The prose rarely surpasses the sixth-grade book report, constantly repeating the prompt, presumably to prove that they’re staying on topic.”
