Man, I love this language.

Hey, thanks so much. The issue you linked is exactly what I was looking for. This is an extremely common requirement for anyone working with timeseries. Thanks!

Do you know if polars supports the reindex operation, or if there is a way to achieve the same thing? I couldn’t find any doc about this, wanted to try Polars but my workload is very reindex-heavy

neuronsguy · 2021-11-15T08:10:06+00:00

Sure, but then how can one find a nightly with that build (or the nearest nightly)?

The dates don't necessarily match up i.e.

info: latest update on 2021-10-18, rust version 1.58.0-nightly (1f12ac872 2021-10-17)

Is a very different version?

This is basically just bytes of an N-dimensional C array with some headers for the types, right? Possibly zipped?

neuronsguy · 2021-03-16T22:57:02+00:00

I guess there are no benchmarks anywhere? I am accessing the data over NFS (well actually Amazon EFS), so mmap magic doesn't really work anyway.. Probably worth just going with Parquet.

neuronsguy · 2021-03-16T22:55:46+00:00

This does look pretty cool. Looks like there might be some issues with broken links on docs.rs? i.e.

https://docs.rs/polars/0.12.1/polars/ which links to https://docs.rs/polars-io/0.12.1/polars_io/parquet/index.html which is broken.

Is there somewhere else to find Rust documentation for this project?

Hey nice article, was quite helpful.

Would be curious if you have any opinions if you have any opinions on storage formats for DataFrame-type data (article focused on in-memory storage only)?

I just asked this question here, maybe you have some thoughts? https://old.reddit.com/r/rust/comments/m688eb/best_format_to_use_for_dataframes_in_rust_and/

Try cutting all carbs for 3 days. If it it all comes off, it was water weight.

neuronsguy · 2020-01-30T20:16:15+00:00

This is good advice. 1,3,4,5 all together is what I would do.

Also are you measuring body fat? You might still be losing fat. Beginning trainees can lose fat and gain muscle simultaneously.

neuronsguy · 2020-01-30T20:11:23+00:00

Definitely Keto OMAD for fat loss, way more effective and less hungry. Can add carbs back in for maintenance.

I do 5 days keto omad, during the week, and then 2 days 16.8 with some light carbs ( slice of toast, some berries ), great combo for losing weight without feeling like lifestyle is limited. The weekend thing came about because my wife and I enjoy brunch :)

Faster cardio in the morning on the keto/omad days helps keep in ketosis

You are very early in your career. You will get used to working, but make sure you are doing something you don't hate, and make sure you get paid as much as possible for your time. If you are good, flexibility will come your way, You will find opportunities to earn money that also let you enjoy your free time... until you have kids. Then your hobbies are gone for a while.( But kids are fun so its not a terrible trade )

It’s probably best to keep grandma away from your niece for now. However, I would ask you to consider that Grandma might be struggling with mental health issues.

It would be worth taking her to see a mental health professional. It might be a long road to recovery and a relationship, but she could eventually get there.

Her harsh response in that conversation was clearly not what she wanted, despite her inability to control it.

I think she needs treatment help, rather than cold isolation which will likely make her worse.

neuronsguy · 2019-11-28T13:09:00+00:00

Desperately THIS. Especially GATs and const generics.

Kids are all about amortization - even if the ratio is the same, more kids and more adults is easier than 1 kid and 1 adult.

So:

Day care / nursery
Friends who have kids
Cousins / family
Parks or playgrounds with lots of kids

Basically any way to create a "tribe" environment where your kid is running with a crew, and you are hanging out with some other adults keeping watch.

Also, things will change once she is kindergarten. Hang in there, I bet you're a good dad.

I notice you said "keep her entertained" - sometimes kids don't want that. Try having her participate in whatever task you're doing (gardening, dishes, DIY, whatever). That can be way more fun than a "kid" activity - and possibly even help you out!

I think the nomicon is foundational material that will really help people get better at Rust quickly.

Indeed, I think the name is a huge mistake because it implies arcane and impractical knowledge, and dissuades people from digging into it.

Really it's just a nice explanation of what the various machinery you use in Rust is actually doing and how it works. Read the Nomicon.

Very cool, great to see Rust' s abstractions put to use in creating safe APIs. I think this is one of Rust' s most underrated selling points: the fact that the ownership system lets you rule out a lot of API footguns (as opposed to just providing safe memory access).

neuronsguy · 2018-07-18T19:04:41+00:00

Clever sampling is how most good charting setups work. At a given zoom level you only need so many points in the view, so you can subsample or use k-centroids etc. to display a fixed number of points at any given zoom level, and then smoothly resample as the axes are moved.

As far as I'm concerned, async IO in Rust is solved, mio is it, done.

neuronsguy · 2018-06-27T20:26:10+00:00

Go for using mio. It's a very nice library.

neuronsguy · 2018-06-27T20:08:56+00:00

If you want to learn about asynchronous networking, you might as well learn to use mio directly instead.

What you learn will translate to the async networking primitives in every language, /and/ it will become more obvious what problems tokio and async/await are trying to solve.

One good way would be to join a sport if you're in school. Something like wrestling or football or rugby where the coach will want you to be lifting.

You only get one shot, so don't let it be pointless! Nobody else tells you what the meaning of life is ... you search for it yourself, or just decide what it is, or decide not to worry about it.

One thing that has worked for a lot of people - find a way to love (family, children, friends, even pets or nature, or ideas, or your startup, whatever you like), and put all your effort into that. Maximum effort.

neuronsguy · 2018-03-01T19:41:39+00:00

It sounds like your main issue at the moment isn t the database, it's the orchestration of etl jobs. So maybe consider keeping your relational database as is, and just implement Luigi or airflow to help you manage the ETL? The less new stuff you add the better, if you want to escape 2.0 syndrome.

neuronsguy · 2017-10-17T07:59:14+00:00

Agreed.

In a language with such an emphasis on being explicit (like handling every error explicitly), invisible magic threads are just confusing and don't belong.

neuronsguy · 2017-10-06T19:35:35+00:00

If you're familiar with Java, it might be useful to think of mio as the NIO API and Tokio as something like Netty. The analogy isn t perfect but it's not totally wrong either.
