The main effect of a reaction time reduction looks incredibly small and is all the way in Fig 6. I would not over interpret this result without higher N and some discussion of effect size.

I'm just waiting for the next massive knee jerk reaction in the stock market to start seriously investing again. AI is not going anywhere even if there is a bubble but people are going to make stupid narratives on it being over for Nvidia and tech.
Time in the market >> timing the market. You’re statistically not better off waiting although ai understand the feeling.

What kids really need is a mandatory personal finance class at the High School level. This would teach them how to handle money, debt, spending, budgeting and general financial health.
In the U.S., we had this for about 50 years, but was mostly gone by the mid-1980's. It was part of a class called Home Economics.
In some schools it was mandatory for everyone. In other schools, it was for girls only because at the time it started, it was usual for women to do the household finances.
The course often also included things like cooking, cleaning, and sewing. What people today learn from online "life hacks."
I'm glad I learned all of those skills in high school. I only rarely need to darn my socks, but the knots I learned translate to fishing and other needs.
It was also where I learned typing.
My middle school home ec class was completely worthless “skills” that weren’t worth the opportunity cost of the time, but a finance class would have been.

There's an interesting housing arbitrage happening right now. Townhomes are still selling for over asking, but single family homes -- ones that older, middle-management types would live in -- aren't receiving competitive bids.
what location?

Across ~10 jobs or so, mostly as a employee of 5-100 person companies, sometimes as a consultant, sometimes as a freelancer, but always with a comfy paycheck compared to any other career, and never as taxing (mental and physical) as the physical labor I did before I was a programmer, and that some of my peers are still doing.
Of course, there is always exceptions, like programmers who need to hike to volcanos to setup sensors and what not, but generally, programmers have one of the most comfortable jobs on the planet today. If you're a programmer, I think it should come relatively easy to acknowledge this.
That sounds ideal! I used to be a field roboticist where we would program and deploy robots to Greenland and Antarctica. IMO the fieldwork helped balance the desk work pretty well and was incredibly enjoyable.

Mine aren't: GIMP is okay, FreeCAD is a complete joke. It is painfully obvious that their development is done primarily by F/LOSS enthusiasts rather than by industry professionals and UX designers. They are closer to being a random collection of features than a professional workhorse. You might eventually get the job done, but compared to the proprietary competition it is woefully incomplete, overly complicated, and significantly buggier.
The poor quality of FreeCAD is the main reason my 3D printer is collecting dust. As a Linux-only user the proprietary alternatives mostly aren't available to me, and FreeCAD is bad enough that I'd rather not do CAD at all. The Ondsel fork was looking promising for a while, but sadly that died off.
Maybe try OnShape, which is browser based and quite professional?

Two reasons I decided not to go with tankless:
1. Can’t have recirculation pump to supply hot water instantly throughout the whole house.
2. Significantly higher energy bill compared to heat pump.
An additional bonus is the heat pump cools my garage in the summer.
1 sounds like a huge inefficiency?

Okay thanks for saving my sanity somewhat.
And also just to nitpick/joke:
> More accurately, it is neural networks which are more "stochastic" with their predictions and decisions <...>
I would defend NNs to not even be necessarily stochastic. I had to handwrite weights for NNs in atleast two exams, to fit XOR for example ;)
that may be the exception that proves the rule here though. Outside of the tiniest toy example is this ever true?
I’ve been hesitant for fear of injury harming the ability to type, but might give it a go in the spring. Thanks for mentioning this I’m inspired to try it finally.
I’ve been climbing for 20 years and it’s the thing that prevents RSI for me and makes it possible to use a computer too much :). Certainly possible to injure fingers but would be a very rare climbing injury that would threaten coding.
