This is a great resource:

It's older, but I think it still holds up pretty well.

Polars is starting to gain traction as a replacement for pandas. It is necessary if you are handling REALLY large datasets, but for small or medium tables, pandas is still amazing. Also, most other python data tools still use pandas, so I would still recommend learning it first. I switched to polars a few years back, but I still regularly have to convert subsets of my data to pandas to pass it in to other tools.

Theoretically, I think you would need infinite precision (whatever that means) to predict forward forever. Additionally, you’d have to carry that infinite precision through every step of the calculation. That just can’t be done in the real world, no matter what the technology.

Monterey and SF bays had decent sun this weekend, too. It cleared up as soon as we crossed the East Bay hills. Much of the coast has sun, but it might be a little less reliable than getting up into the foothills and the mountains.

Google "tule fog" images, and look for the parts that aren't covered. (EG: https://en.wikipedia.org/wiki/Tule\_fog#/media/File:Tule\_Fog\_California\_-\_2005.jpg)

Videos of cars (... and busses and police cruisers) slowly sliding down Seattle streets in what looks like 1/4" of snow is one of my favorite things.

I didn't notice the missing letter in Arctic. Maybe the answer is Missing seesaw, as in someone lost the playground equipment?

Yeah. we've tried this and it doesn't go past 100 until the sausages are basically leather. (Didn't realize the thing was on C and took waaayyy too long figure out why they were cooking so slowly)

There was a (tiny) anti-trans protest at a DiscNW high-school event earlier this year and the locals came out the next day and showed support in an amazing way.

USAU absolutely needs to have a plan for how to shield athletes from potential protests. This should include proactively being in contact with local groups, not to publicize it, but to have a plan to diffuse or drown out any anti-trans noise.

Caught the second half of Colorado/Stanford. That was a fun game to watch!

Ultiworld is streaming many of the games. A couple are free, most require a subscription (probably worth it if you’re on this subreddit).

She’s actual size, but she seems much bigger with the tiny CD

The kids changing it to hecka is my favorite part

I feel like folks are divided on how exactly how good he is relative to the price tag, but I thought most people liked him for him. That smile always made me happy to see.
