Now that @ryanmurphy42.bsky.social has helped me fix what's wrong with my code (grrrr @ undocumented APIs), yes πŸ˜›

In my defence it was the objective function I was attempting to optimise in my code this morning πŸ™ƒ

It's Sunday and my brain's in a work mood. Better go satisfy it, sigh. At least I did meal prep yesterday!

Also resuming teaching this coming week after effectively a year off. How rusty will I be, I wonder? πŸ™ƒ

Thanks for writing this up!

I wasted like 3 hours on trying to debug a specific issue with a specific submodule not appearing in my Julia code and the answer ended up being that I just had to update all my Julia packages arrrrrrrrrrrrrrrrrrgh.

I'm just glad I'm bullheaded enough to persist πŸ˜’

I've spent way too much time fixing my PC 😭I think I've fixed the overheating issue at least (and learnt that I have an AIO water cooler, and how to distill water on the stove)!

But now it won't boot to BIOS, grr. I've got a list of things to try for tomorrow, at least.

If you're familiar with LaTeX and have Lean set up in VSCode, then it's basically \alpha,\beta, etc., and there's also typed shortcuts for relevant Unicode characters as well e.g. \r for the set of all real numbers R.

I'm in one discord server full of neurodivergent friends that are very much like this in terms of spread of professions πŸ˜‚ I'm essentially the resident academic.

I'm guessing that idiomatic Lean wouldn't follow the same flow of the proof in the written version then? Interesting πŸ€”

On top of my home PC having a weird CPU overheating issue I've also misplaced the crochet hook for my shawl and it's like "I REALLY don't need small minor irritating things piling on top of each other while I'm in a pretty exciting moment of my PhD" 😭

It feels crazy that I can come up with a multi-ODE model and use a(n incorrect) numerical solution to fit experimental data to such that I can find the values of parameters that match said experimental data 🀯 Not needing the exact solution!

And yet, I did that this morning 😁

Econometrics and sabermetrics definitely gave my brain a good flip when I first realised what they covered. "Wait...this is just all (mostly) stats!"

I feel this. I've been to an audiology conference, and was accepted to present at an accessibility conference in a few months. My background is in maths πŸ˜‚

It'll get easier after the first!

From what I've seen each specialist life science subfield are pretty stringent on keeping "computational [subfield]" distinct. I was surprised to see "computational audiology" be a thing but it makes sense.

It's also expanded to include probability (e.g. Markov processes applied to evolutionary trees), statistics (e.g. Jen Flegg + Malaria), and other maths fields. I do know of some theoretical math bio focusing on graph theory and combinatorics.

I'm randomly listening to the cello Bach Suites in baroque tuning and I'm noticing I like the baroque tuning on the minor keys more.

However I suspect it's also because I perceive the 415Hz tuning to be flat which emphasises the minor nature of the keys, which seems...wrong?

If anything, this is motivating me to try and have more hard and emotional conversations even through they feel absolutely terrifying and I hate making others emotional and uncomfortable. If I want to lead others eventually I have to be good at that.

I think the part that's made me really jaded is the existence of a management strategy for those lacking a moral compass.

Like I knew it existed in politics so theoretically it'd exist elsewhere, but it's my first time reading about the details.

Same guy posted again on what he'd advise ANU do now depending on whether they pull back & apologise or go scorched earth. Also a long read.

Was nerd-sniped today by a SeriousEats article about cooking+resting steak, then I wondered if any mathematical modelling existed for cooking steak.

Some searching turned up this one for double-sided pan frying. Hehehehehehehe.
