This kind data modelling happens all the time in quantitative finance, where you need to run historical scenarios (backtests). We just call that "point in time" (PiT) data. There can be multiple dimensions of timestamping, but you

"Cheaper" is not the only dimension to consider. Using managed services is also faster, more reliable, and scale better. You cannot just get that for free.

You don't have to use AWS' appliance (the NAT GW) to do NAT. You can NAT your traffic yourself from a t2.micro Linux. AWS used to maintain a AMI to do just that, nowadays you have to do it yourself, but it's honestly not much

> isn't investing into a company with a bad ESG sub-component(s) a good idea? Yes, that is the paradox of the ESG finance trend. Using a quantitative approach, you can use the CAPM to show that at equal risk/return, increasing

I don't quite see how Rust approach to multithreading is that amazing. Rust does nothing to magically prevent race conditions for you. Rust safety does not encompass race conditions, starvation, etc. What it does is defensively prevent

> No, no the same thing. Well to me it is the same thing. Two threads sharing state through a common heap, or two processes sharing state through a shared memory is pretty much indistinguishable, at least on Linux. The question is not mu

Not sure why this is downvoted, I never had much issues with the GIL as well. Multiprocessing does the parallel computation pretty well as long as the granularity is not too small. When smaller chunks are needed most of the time that's

by Galanwe 3y ago
I don't quite get your "unpopular opinion". First, I don't see how the GIL would have much to do with free multithreading. The GIL should not have much observable logical impact on multithreaded _Python_ code. It should

Note that you're also not opting out of "meilisearch telemetry". You are sending full laptop specs of your users to meilisearch. Which in turn sends them to Twilio apparently.

Well not every program has to be a super robust daemon recovering from any kind of problem. There's a good bunch of programs that are just supposed to read some inputs, perform a task and crash with an error message and exit code if an

Reading articles and publications is part of the job of quantitative research, and being a judge of their quality and reproducability even more so. So, in all fair honesty with you, no I will not give you recommendations.

While I agree that the article is somewhat vague and imprecise, it is not accurate to encompass all statistical predictions as statarb either. That would more be what "quantitative" is. For a strategy to be considered statistical

What is showcased here is a dummy pair trading example on single stock vs basket. Of course it does not work anymore. There are a lot more evolved kinds of statarb though, that still work nowadays, and most likely new ones that we don'

There are more dimensions to this that just the tech stack. - Industry: focusing on big tech or quant finance would be a good choice. That's where the money is IMHO. - Expertise: if you invest on being the best, that will pay off. - Ne

If I understand correctly, you have a remote server with a logfile, and some markers in this log file tells you whether the build is in process or finished. I would suggest you keep it simple and simply poll the logfile for the latest occur

EA is a philosophy, or a mindset. It is not defined by the actions of some group of people that pretend to follow it. There will always be some % of cheaters in whatever human system that exists.

I don't think one donates money to Harvard just for the sake of a plaque. I guess there is some sort of indirect benefit to be had after such a donation, like an entry pass for a child, an entry pass for a PhD, or something of that vei

Hum, but my understanding was that the whole point of the normalization was that the raw scores are not in a scale that is meaningful outside of the symposium which they were placed in? Does it really make sense to compare raw scores from d
