TFW you log into a meeting only to discover that you royally screwed up the time zone it was scheduled for and missed it by n hours

I missed a few...make it at least **eleven** different class action lawsuits in the last 12 months.

In addition, almost every class-action notification goes straight to Spam because they are always sent with shady-looking links and weird addresses which get auto-flagged as suspicious.

I got curious and did a search through email...over the past 12 months I've been a member of at least **eight** different class action lawsuits. I feel like this says something about society, but I'm not sure what. I suspect it says a lot less about me, beyond being an active member of said society.

For those interested in a non basketball bracket this March, I direct you to the #FiddlerCrabBracket I posted 2 years ago, memorialized in order in this Google doc

I challenged my collaborator to try a different genAI: they got the exact same formula and a completely different wrong answer. Turns out the genAI cannot handle the large integer math, but rather than admit it cannot, it just reports some answer that is orders of magnitude incorrect.

When we discussed it, we confirmed the formula was right, but whose numbers were correct, mine or theirs? (Mine obviously). I had calculated the values in Python, but then showed that I got the same values out if I plugged them into a website combinatorics calculator.

I mangled my explanation slightly. My collaborator dumped the problem into genAI and got a formula and numbers out that did not match mine. They tested the formula by hand for small values (literally writing out every possible combination and counting them), so they knew the formula was correct.

I was exchanging notes with one about a project and I outlined that one element was essentially a simple combinatorics problem (n choose r) and listed the very large number of possible outcomes in a table.

Another example of AI failure.

I will not use generative AI. Full stop.

However, I have collaborators who will for minor purposes.

A head with protruding tongue has appeared. Appears to be mostly still asleep and confused by the bright light shining in its face. #cats

Good article, but the framing is wrong. There is not a dearth of interest in taxonomy. There is a scarcity of funding and positions, which is a deliberate choice by funding agencies and institutions. The youth love taxonomy! It's the olds that are failing to meet their passion!

Looking back at 2025, I realized I posted a deficit of cat photos, so while not a New Year's resolution per se, I aim to be a bit better about keeping the "Internet Cat Photo Gods"β„’ appeased this year.

Here is Normal, ~11 months old, asking why I'm shoving my phone in his face.
