I don't think you can draw that conclusion from that code. I've been using Python for a few years and moved some projects to static type checking. It's not always worth the cost in every situation, of course. For such a simpl

I think that's their point. There's a lot of discussion that 'banks will become obsolete with crypto' that forgets that banks are not the currency, they just manage it. If crypto becomes widespread banks will keep on exi

The fact is pretty much hidden. I tried to link my Toshl (a budget app) account to my bank, to import automatically my movements. I saw that they were using Plaid, and I found that weird. I went to search the page you linked, and I still di

And a conversation is a search over a countably infinite tree too. My point is that even though some things have technical similarities, in practice they are very different challenges.
699.
by gjulianm 6y ago
Yes, but it isn't useful. A conversation also has three outcomes (neutral, you like the person more, or less) and yet it doesn't make conversations similar to chess.

The search space for proofs is far bigger and less structured than a Go game. A lot of proofs also require creativity, in the sense that they aren't just "find the set of logical steps from 'initial condition' to 'p

Out of curiosity, how does the app make you enjoy the process? I took a quick look and it seems to have the same basic progression that most classes have, I assume the paid courses are different and better but I can't see them.

by gjulianm 6y ago
Yeah, I fully agree with that. Only thing is that I do think that a teacher can give you motivation by pointing you towards a next step that is both achievable and interesting for you.

by gjulianm 6y ago
Of course, and to make decisions you need information, that's what I'm trying to do. Also, you can have a teacher where the focus is to have fun with it and not drilling boring stuff. That's precisely the conversation I had w

I'm not a classicist in fact. If you're Thelonius Monk go ahead and play, but in this same thread we have some people complaining of finger fatigue and cramps. That's something that a teacher can correct easily.

by gjulianm 6y ago
If that's what you want to do, that's nice and go ahead, maybe the app is the cheapest way to get to that point. My point is that people who use them should be aware of their limitations, and compare that with what they want to ac

That's the main issue with teachers. Bad teachers can really make you quit an instrument, same with parents forcing kids to go to lessons. Luckily I think here in HN most people will be able to choose a teacher and leave it if they don

Sorry but I have to disagree a lot. An app is not the best way to learn piano. Piano is not just about pressing keys. Does the app correct your position (important if you don't want to get fatigue and cramps), your volume, fingerings,

I think the parent talks about the relation between miss/hit, not the actual cost of a miss. In other words, if a piece of code took 100ms with 100% cache hit and 200ms with 0% hit but now it takes 20ms with 100% hit and 100ms with 0%
