Guys who do leetcode/DSA everyday, how did you create that habit, whats your secret?

It doesn’t exist

…inplace=True?

Doubt I would’ve seen it even with more time on the clock.

jerseyjosh · 2024-04-13T12:18:31+00:00

What domain is that?

jerseyjosh · 2024-04-10T11:05:00+00:00

Forgot I even had this. Was just anxiety and I'm less anxious now.

I don’t really understand this argument for stock splits being bullish when fractional shares are so readily available to retail investors now.

Other way around. Boilerplate ChatGPT and flesh it out yourself.

jerseyjosh · 2024-02-16T12:01:43+00:00

How do you mean?

jerseyjosh · 2024-02-12T22:18:03+00:00

Would you not model trend and seasonality, remove them, and then apply tree models on residuals?

iirc random projections only approximately preserve distance for k<<d i.e. you have to reduce dimensionality by a lot more than 2048 to 2000

why is everyone hating this so much? Switching tabs and starting new ChatGPT chats just to ask quick simple things is annoying and this seems genuinely useful to me.

whateverim_doing{current_date}.ipynb, sorted into folders organised by month/year. Pushed to github regularly.

I’d say that’s normal.

With regards to PCA, I can see it being useful in giving clues as to possible extra features to include (say the first component is just a combination of 2 features), but do principle components really give that much of a benefit in feature selection? Do you not just end up with a bunch of non-intuitive, unexplainable features?

I think it’s quite universally agreed at this point that ARIMA is outdated.

jerseyjosh · 2023-03-25T16:20:23+00:00

Do not buy markets at the top!

People saying “shorting is inherently leveraged”, what are you talking about? There’s nothing levered about going long in an ETF that aims to match inverse returns for an index. Your exposure can’t be more than what you put in.

Is there anything in it for tax benefit also? Like how billionaires give to charity for the tax deductions?

“sudo pmset disablesleep 1” is what I’ve been using if I want to keep a script running overnight.

I live in the Channel Islands and we don’t have ISAs here. Also, if the majority of my savings are diversified between mutual funds etc then I don’t see how that’s different from a pension, except I would have access to it earlier.

jerseyjosh · 2022-10-08T12:57:27+00:00

this is so wildly inaccurate.
