You just deleted 600 unread emails. Finally, inbox zero. Phew! You refresh the app. There are 600 more unread emails. There will always be 600 more emails. You close your laptop in frustration and look at your phone, only to find there are 600 more emails there too. You cannot escape 600 more emails

This case highlights a core issue with grades that LLMs have brought to the fore: we are using grades to try to measure/do too many different things: 1. learning+readiness for later material 2. teaching effectiveness 3. Sorting by latent ability 4. Effort put into class 5. as a tool to open doors

Today's ragebait for the professors who follow me. 3 points: 1) if I am a student, a take home exam is implicitly open-book. Using ChatGPT is fine and no different. 2) the professor changed the rules after the fact. The students should be pissed 1/2

the British monarch gives a regular speech to parliament and in the room where they make them wait before going on there’s a framed copy of Charles I’s death warrant. just a fun historical fact, no reason to bring it up

Democrats give a big standing ovation and start hooting and hollering when King Charles III says "executive power is subject to checks and balances." Republicans join in the standing ovation but remain quiet.

I've been working with NCV this last week; it's a powerful tool for modelling data with dependencies that are poorly/inefficiently modelled via stochastic process priors like cov functions or low-rank smoothers. However, it's a complex topic, so I thought I'd summarize the key ideas in a thread 1/n

Saw that "neighborhood cross validation" was recently added to `mgcv` but I haven't had the chance to kick the tires. It sounds useful, but the effort of setting up neighborhoods vs modeling the correlation directly is something I'll have to sit with! stat.ethz.ch/R-manual/R-d... #rstats

We must never let it revealed to the world that Hawaiian pizza is a Canadian invention

Canadian inventor of Hawaiian pizza defends pineapple after Iceland's president disses fruit topping | CBC Radio

After the president of Iceland announced he was fundamentally opposed to pineapple on pizza, we decided to call up Sam Panopoulos, the Canadian inventor of the Hawaiian pie, to vouch for his creation.

As a Canadian, even I'm not sure what Canadian food consists of. But it definitely isn't this. (Tourtiere! Things with maple syrup on them! VERY reluctantly I am forced to admit poutine! And yes, @carlyziter.bsky.social, butter tarts!)
