Making notes and re-writing in your own words have actually been found to not be very useful to memory formation [1]. Completing exercises works great: this corresponds to reviewing cards. Explaining it to others also works OK, but I&#x27

Agree that "firing everyone" is exaggerated, but what we're seeing now is pretty unique. Headcount increases between 2010~2022 at these companies were around 15~25% CAGR; now, it's at best flat for the past ~3 years. I t

Thanks for sharing the test. I'm surprised you aren't able to tell the difference -- I can pretty consistently (90%+) get the right answer to both sides at 120 fps "fast," speeds as low as ~500. At higher speeds it'

It bums me out to see much of the reaction here questioning whether this will last. I think that it's fair that the headline is likely taking it too far -- there will always be interesting new ways to rip people off. But I also believe

we've already given up 80% of the street space to be a machine-exclusive area (the road). let's keep at least our tiny 20% for humans.

You're looking at total atmospheric CO2, which is increasing at an increasing rate. The OP's claim was about CO2 emissions , however, which are increasing at a decreasing rate.

Careful with trying to generalize personalized insights from therapy! Everyone is different. I believe advice giving (& receiving!) is very difficult to do well, even with people you know personally. For strangers on an internet forum,

Varies by friend. Some are open to it, others not so much. In general I've found that talking about trauma with friends isn't very useful even if they are willing to engage.

Great write-up. I especially liked > I find the common advice of “write your own cards” misplaced: you pay the opportunity cost of not reviewing all the cards you don’t make. This perspective of cost is a nice way of putting it. The othe

I was convinced of this line of thinking for a while too but lately I'm not so sure. In software in particular, I think it's actually quite relevant what you can do in-house with a SOTA model (especially in the tool calling /
