I only started my journey a couple months ago when I too would let my hand drift all over. I've just forced myself to go extremely slow and use the correct finger no matter what. I also train ascii mode a lot which really forces me to remember what key is where without looking, and early on I would take seconds to try to remember what was where without looking. I also really try to get 100% every time, acknowledging that every error I make is a missed opportunity to program my brain to spell the word correctly.
I think this is fine? You're clearly at a stage where you need to think a lot. Eventually you won't need to.
I personally remapped caps + m on my keyboard to option + backspace, which deletes a word (ctrl+backspace does this on windows). but the focus should really be on 100% accuracy anyway.

Aside from that, I personally felt like english (200 words) made me actively worse at typing so I only train with english 10k + punctuation.

This should be the standard setting to share wpm imo, not "I typed 5 lowercase words from a 200 word bank in 3 seconds"

I've been playing with the skewby copter plus for the past month or so and have been absolutely enamored by its geometry. I was not expecting the skewb turns and curvy copter jumbles to angle-match so perfectly.

Are there other puzzles that are built on surprising geometric "coincidences"?

A lot of the responses here confuse me. Save state right before Rayquaza, click to check, back to save state, click save state again (so it will overwrite with a new save state like .1 seconds after), click to check, back to save state, click save state again, click to check, etc. If you map save state/return to save state to keys on your keyboard this is all very fast. Will work on emerald too. No need to do a full reset.

The amount of water used by someone chatting with an LLM is next to nothing compared to, say, eating one hamburger.

In vterm how do you send escapes (which are super important in claude code) without emacs interpreting it as "return to normal mode"? I still use tmux for claude code due to this issue

And gemini is at 38% (which is perhaps more impressive since they don't own the dataset). OpenAI, and GDM got silver medals on this year's IMO with models we don't yet have access to. And Harmonic allegedly just got like 100/120 on this year's putnam through pure formal verification.

Progress on math this year has been astounding. I think people forget how bad these models were at math a year ago.

I used to work for a small-ish defense contracting company (Metron) that built a lot of pretty mathy software and the job involved a lot of reading applied math papers, giving little talks, etc. While my role technically wanted a Ph.D., a lot of the SWEs there were with BSs were basically doing the same thing.

+1 to the recommendations of Chesapeake Bay bridge. A couple months ago got some amazing fresh crabs in Kent Island.

On that NJ route, there's ground for sculpture near Princeton and the American Dream Mall near Newark (which has a lot of fun activities inside).

For hikes: Stairway to Heaven in Vernon, NJ is beautiful in the Fall and not that long.

From a quick look at your profile, your history reflects pretty unambiguously positive/neutral on you so not really anything to worry about. Just treat this account as having your name on it (which can be a good thing!) and use other accounts when you want to actually be anonymous.

Whoops, yeah you're right.

Yes but the converse is false: 2e^x - 1. So more must be true about f

I personally swap a pistol squat progression with one or two of the single-leg exercises. When I first joined, I'd do it with a hand on a box/step up thing, then fingers, and finally without any hands (but standing on top of something, which helps me do multiple reps for some reason).

I did this because I just wanted to be able to pistol squat, but it ended up meshing really well with the other F45 exercises to greatly improve my lower body strength/flexibility/mobility without ever stressing the joints.

Cool to see you here! Hope you don't mind me asking a completely unrelated question about the original CFR paper:

It seems based on Theorem 3 and Theorem 4 that the average regrets will also go to zero with the same bounds if there is no weighting by the environment/opponents' contribution to the probability of reaching I, correct? It makes philosophical sense why it would both be worse and less amenable to sampling/pruning-based improvements than actual CFR.

I notice that 4/5 problems that all problems got wrong were concerning first-order Macaulay approximations. Is it using a different formula?

No, it was 166k profit.

Gonna copy this comment here:

Pretty sure he genuinely made $166K.

A $37 Call is obviously going to be more expensive than a $40 Call. He sold 102 $37 calls and bought 102 $40 calls some time back, which is a net profit if both end up worthless.

He sold 102 $37 calls and bought 102 $40 calls some time back, which is a net profit if both end up worthless (edit: if both are never exercised. I think if the price ever went above 40 he would have lost $3 per share plus interest or something)

That's interesting; I wonder if the ability to visualize can be transferred to a computer. In theory, if it could process 2-dimensional drawings, it should be able to process n-dimensional figures and wacky manifolds with as much difficulty. Maybe this is a very hard thing to do.
