I mean, you don’t believe that, do you? Maybe we should all be writing our own sorting algorithms as well. I kind of assumed that DRY was a universally accepted principle in software engineering. But I guess the Pythonic way is about copy a

What tangible advantages does Python have compared to Racket? The only thing I can think of are the high quality data science libraries.

by mruts 7y ago
Yeah, of course you can flatten a list. It seems like Python programmers enjoy writing the same code over and over again. Would it really be bad if I could just do lst.flatten ? Or flatten(lst)?

Honestly, it’s pretty easy to create a rough approximation of many popular hedge fund strategies. Like on Quantopian, it’s pretty easy to whip up a simple factor strategy in a couple hours. The returns aren’t bad, either. The part that is h

If any wants to try their hand at quant trading, Quantopian is a great place to get started. Great data sources and you can get allocated capital and make a little bit of money. Also the competitions are fun and you get paid $50/day fo

Then why isn’t there a function to flatten a list in Python? I’m not sure what Python’s priorities are, besides majorly sucking. I can write software in Scala or OCaml or Racket in less than half the time of Python, while also being 10x fas

I sometimes watch analysts at my firm use excel. It’s pure magic in the right hands, absolutely sublime.

The biggest determinant of a company's stock price is not the company. It's beta, interest rates, and a multitude of other factors. The idiosyncratic return and variance of most companies is quite small compared to the systematic

The US is a lot less dense than the UK. Whenever people complain about fiber internet or mobile in America, I try and remind them that the subscribers in urban centers are subsidizing those in rural areas.

This is all true, but short sellers can (and do) depress the price of a stock in the short-term through the act of selling.

I think you misunderstand the genericicity of macros in Lisp. Macros take one or more S-exps and return and S-exp. nothing more, nothing less. There’s no reason why macros need to generate valid code. Though in Lisp, it’s pretty easy to mak

CS isn't anymore of coherent subject than, say, math. And (much like math), the useful/practical parts that'll get you 80%-90% there in solving arbitrary practical problems aren't all that difficult to learn. Just learni

Very nice! But is Python the right choice for this? It seems like the macro rewriting abilities of Lisp (especially Racket) would be a perfect fit for this project. And he's already using S-exps, so why reinvent the wheel?

Scala futures seem to offer all of this functionality as well, no? And you can do all the regular monad stuff on them as well, which is super nice.

I think so. You’re always going to lose money by laundering it. Also combined with the low upfront investment (it’s pretty easy to set up new apps), it doesn’t sound like a bad idea to me. Using a real physical business has a lot of problem

What percentage of the population has air conditioners? Also, what do you think would happen if you didn’t have one? I honestly can’t imagine that kind of heat and how people could even survive in it.

Maybe because governments aren’t all the same and not everyone comes from the same country? What you mean we, kemosabe?

I would say unequivocally no and it shouldn’t be enforced at all. So, like, if someone is brain dead, the website needs to pay for a new brain for them? What you’re saying doesn’t make any sense, online or offline.

There's not a market maker in America that's selling and buying in order to provide liquidity. You buy low, and sell high, that's the end of the story, for both proprietary trading, trading for clients, and market making. The

I mean, that’s the most common argument on why tabs are better the spaces. It’s also an argument I tend to be sympathetic too.

The rule they are talking about is the Volcker Rule. Prevents certain banks from proprietary trading. They are only allowed to buy and sell for the purpose of market making. This, of course, is an incredibly stupid rule. There’s not really

The harder you think it’s going to be the market, the less you are going to trade. You need your confidence interval to reach a certain point before you are going to trade since you’lol have a negative expected value if you don’t have an ed

reductio ad absurdum is a perfectly logical syllogism. I guess it depends on how angry I was? Would you kill someone who slept with your wife? Regardless of your answer, it would be absurd to call everyone who did crazy. In fact, courts nev
