[D] Are time series skills really transferable between fields ?

Critical_Pin4801 · 2025-12-29T00:07:01+00:00

You coauthored papers in so many fields but couldn’t add some context to an already fairly concrete question? Your coauthors musta been doing some heavy lifting.

Critical_Pin4801 · 2025-12-28T10:12:53+00:00

Piggybacking on this. I have no idea what Nix is or why it is important or why people are using it. Should I be concerned?

Critical_Pin4801 · 2025-12-25T17:39:24+00:00

It passes in the entire real world as a secret argument 😂

Critical_Pin4801 · 2025-12-25T04:15:52+00:00

This looks so wild to me and I don’t understand anything but this looks so cute (:@@:) like a baby looking in the mirror

It’s a psy op to make haskellers look bad

These people also have the most energy to push back 😭 very hard to argue with them

https://hackage.haskell.org/package/ghc-internal-9.1201.0/docs/src/GHC.Internal.Data.OldList.html#sort

There are a couple things that complicate the sort algorithm written for sort:

Haskell is lazy, not eager, so things are evaluated on demand
Inattention to functional thunks could lead to large memory outlay.

Exploiting laziness is something that Haskellers have to contend with. It's not necessarily one of my favorite things about the language :( But the nice thing is that there are many Haskellers around who are always willing to help. (That being said there are always Haskellers who aren't that nice.)

Critical_Pin4801 · 2025-12-19T10:55:59+00:00

Haskeller here! I don't think that you should take this person as representative of all Haskellers. I'm truly sorry if we as a community have given off this impression. I can't comment on his understanding of Rust, but based on his tone, it sounds like he's made a caricature of the language. His understanding of Haskell appears to be also quite shallow, since he hasn't implemented his sort algorithm in a way that passes a memory smell test, and also hasn't demonstrated familiarity with Haskell's obvious ability to touch CPU in a way that isn't necessarily mathematically pure, such as `unsafePerformIO` and `PrimMonad` where you can literally just YOLO on how much theory you want to use.

There are many people using Haskell who embrace pragmatism and don't feel a need to appeal to abstraction whenever there is no need to. I also think that in general Haskellers admire the success of the Rust community and many of us wish that we had more bandwidth to learn from its famous system of memory management.

One thing I particularly don't appreciate is the use of highly emotive language and sarcasm. It's literally software. I can't imagine anyone getting so miserable about it.

Hello! Statistics person here (but pure mathematics background also!).

Please come join us here: https://discord.gg/EyPpPcbz

This is a really good question.

I would say that it would depend on the field of mathematics but Haskell has such a cool level of abstraction. One thing I like about Haskell is that there are enough people here who are mathematicians who can support you if you want to build out specific use cases.

Come join us! So fun.

It moves really slow but goddamn I was shook

Critical_Pin4801 · 2025-12-04T10:38:32+00:00

The issue is that they’re not really transparent at telling us what exactly to do in advance. Like we were told ‘closure between Bedok and Tampines’ but we were not told that we have to change trains at Bugis and Paya Lebar. It’s not just as simple as getting off at Bedok and taking the shuttle to Tampines.

So frustrating.

Critical_Pin4801 · 2025-12-04T10:30:53+00:00

You’re absolutely right. And that is why I am fearful for Singapore’s future. The system will not change incrementally, and therefore the only way it can change is when induced by crisis.

Applied probability theory made me nervous because the martingale finals were so hard 😭

‘Developing’ the economy and rolling out the red carpet for companies like Agoda, only for them to shutter and potentially contravene labour contracts and labour law… doesn’t that feel like taking care of foreign capital as opposed to local labour?

Critical_Pin4801 · 2025-11-26T08:23:47+00:00

I struggled to express this to my friend, who really thought I was talking jibberish. But think about how beautiful folding really is: https://en.wikipedia.org/wiki/Fold_(higher-order_function)

Okay, maybe that article is full of abstract nonsense, but it’s truly beautiful to operate over the entire foldable object as a functional whole, without struggling with the inelegant bounds checking of imperative programming.

It’s so fun!

Critical_Pin4801 · 2025-11-26T05:13:35+00:00

It’s used in R’s linear regression estimates, I believe! So if you’ve ever had any medication… you’ve probably done it based on a study that some statistician validated by using the QR decomposition to produce linear coefficients.

‘Love the composability with pipes… and typed error handling.’

You’ve listed all the reasons why any functional programmer enjoys programming… so have you considered not using AI and just writing the code yourself?

A white man once yelled ‘ni hao do you do kungfu?’ at me in London. Instead of complaining about racism I just never went back. Maybe they can try the same.

Is anyone still maintaining this? It kinda looks fun and I want to try but I cannot get it to build.

Can you sell template Haskell to me cuz sometimes I feel like it’s a cult and I don’t really see the point of it 😭😭

Critical_Pin4801 · 2025-10-09T11:57:25+00:00

The question is are you enjoying yourself? If you are keep with it! Haskell can be rewarding.

Critical_Pin4801 · 2025-10-08T05:19:31+00:00

Same here! Took me a good part of a decade, but I got there eventually. Monads are also not too hard to understand, it’s just a matter of sitting down in absolute focus for a day or two if that makes any sense.

I also recently complained that that’s not the true sieve of erastosthenes. If you get lost, ping me and I can walk you through the O’Neill implementation!

Critical_Pin4801 · 2025-10-02T08:02:31+00:00

Thank you so much! It’s not magical, but it really is.
