Our dog groomer has a special on Fridays -- "nails trimmed, half off."

Here you go! This lecture (phrased to hopefully be useful to people even outside of the class I'm teaching) goes over the 5–6 GA hyperparameters and hwo they fit on the diagram above.

Looks like Facebook is starting to blend its spam together. It's a bold strategy, Cotton. Let's see if it pays off for 'em.

In case it's helpful for anyone covering metaheuristics, here is my handy guide for choosing the major hyperparameters of a Genetic Algorithm. I tried to bring in more inspiration from popgen as well as breeding while keeping an engineering (instead of breeder) perspective.

I generally appreciate scientific societies, but the IEEE continues to be a total scam. So, I saved $510 off my membership by being a member? I guess those who specialize in circuits shouldn't be faulted for circular logic...

For anyone with an #Amazon #Echo device without a physical volume ring, you can get early access to #AmazonAlexa's #AlexaPlus. Sadly, the on-screen UI is half baked. Example: Below is the legacy Amazon Alexa with a yellow bar indicating a notification on my Echo Show 5. That bar goes away in "Plus".

I told #AlexaPlus a dad joke about bookstores. She understood the joke and inferred that it probably caused my wife to give me an eye roll that "could shutdown a bookstore faster than Amazon."
I was taken aback a bit by an #Amazon AI joking about killing bookstores!

At least three robot vacuums are in development that aim to conquer stairs. #RoboRock already has a robot with an arm that picks up your dog toys, and the stair climber it is testing has two independent *legs* that make it particularly agile.

Hey, @drdorotask.bsky.social is here on Bsky!
Such cool work.
We think that retinas degenerate with time and that if all of us live long enough, we’ll get AMD or other neurodegenerative diseases.
But Greenland sharks manage to live for hundreds of years and repair their eyes.
How?

When I explain to people what is involved with writing a successful grant, they simply don’t believe me.
I explained it once to a famous person from Pixar, and he looked me square in the eye and said: You mean all the cancer and Alzheimer’s grants work that way? You’ve gotta be &$%#ing kidding me!

I don't think you non-science people realize what it takes to get a grant funded by NIH. Started experiments in Sept 2021 to generate 3 new mouse mutants to model human disease. Prelim dara shows they have relevant disease phenotypes worthy of study. Need a small grant first to characterize /1
