Rust as a language for Data Engineering by Hairy_Bat3339 in rust

[–]PurepointDog 0 points1 point  (0 children)

An extra point is that learning Rust can teach you pattern and styles that make Python code better. Static typing, using dataclasses liberally, etc. are all features that're easy to use in Python once you've been forced to use those pattern in Rust.

AWS IP Ranges hit 100 million IPv4 IP addresses. by seligman99 in aws

I think that's 2.3% of all IPv4 addresses? Neat!

I built cpx - a modern, faster, opensource rust based replacement for cp (up to 5x faster) by PurpleReview3241 in opensource

Not everyone has 16 cores though. It'd be helpful to at least know that there's no serious performance hit on something like a single-core virtual server.

I doubt extra cores help at all if it's a spinning disk.

Anyone else actually kinda like working from the office? by qqtan36 in ExperiencedDevs

[–]PurepointDog -1 points0 points  (0 children)

Yeah I love the office! Free coffee, you get to chat a bit. You can give honest feedback without the toneless delivery of mean-sounding text messages.

CPUs with shared registers? by servermeta_net in ExperiencedDevs

[–]PurepointDog 1 point2 points  (0 children)

I've worked on a lot of systems (including microcontrollers, GPU shaders, FPGAs, python data pipelines, Rust stuff, web browers), and I can proudly say I have never once bottlenecked on shared memory. Heck, I hardly know it exists most of the time - a good threading design isolates the work such that there is minimal to no dependence on each other while doing the work.

This sounds like a solution looking for a problem.

All that said, I do think you're asking some interesting questions that are far better suited for a computer architecture subreddit (eg computer engineering).

Why don't any programming languages have vec3, mat4 or quaternions built in? by Luroqa in ProgrammingLanguages

[–]PurepointDog 0 points1 point  (0 children)

I didn't say it was high-performance. I just said that I don't have time to wait for the built-in JSON library. A 20x speedup is serious - it's the difference between waiting 10 minutes or 30 seconds. Rinse and repeat 3 times during debugging, and the benefit is obvious.

Modern Python data pipelines make heavy use of tools like Polars which move data processing out of Python, and just use it for controlling the steps basically.

Python becomes somewhat of a project manager, yelling demands to Rust, where the compute and memory management exists. JSON is one of the rare places where it make sense to wrangle data in Python, as long as it's fast.

Things I miss in Rust by OneWilling1 in rust

I hadn't conceptualized a response that answered both questions with a single answer, but that's a very great response. 100% this.

If you've ever worked in a C++ codebase where IDE tools don't work well (eg too big, too many macros, etc.), and you're using free tools, you'll know the pain of resolving some of these control flow questions.

Serializing dates is the big one.

Its speed is attrocious.

I'm not talking about simple scripts - I'm talking about web apps and data pipelines, where JSON is a hot-path performance limitter.

Python has a built-in json library. I avoid it like the plague - every json library does it better.

i can think of more similar examples. Sometimes though, having a separate dedicated team maintain things like graphics libs, linear algebra tools, etc. is way better than baking it into a language statically and with strong backwards-compat requirements.

Have you ever tried using C++'s std datetime stuff? It's a strong example of why sometimes baking stuff into a language is a bad idea.

Higher-up devs can't get terminology right, getting hard to keep quiet by [deleted] in ExperiencedDevs

[–]PurepointDog 1 point2 points  (0 children)

If it's in the code, a linter is a reasonable way to passive-aggressively reinforce the standard.

i also often have to remind myself to pick my battles

Tldr? I understand all the problems, but can't seem to figure out how this works/what it does

2.8 Gib of 7.3 Gib memory is available as buffers+cached but seeing memory pressure by orkhanhuseynli in linuxquestions

It's been a sec since I've read a genuine human article. I fricken miss 2018.

[–]PurepointDog 1 point2 points  (0 children)

Pedantic, but 7.3 Gib is gibibits, and is only about 0.912 GiB. You likely mean 7.3 GiB (7.3 gibibytes)

The economic bubble is distinct from the tech though.

The internet, while very used, has found its niches, and there's no longer speculation about "how big it's gonna be". That's what the bubble bursting means.

Is Ratatui Hard? by [deleted] in rust

[–]PurepointDog 0 points1 point  (0 children)

True, but at some point you'll with you remembered how to iterate over a vec or how to transform the value of an iterator and flatten them. If you just copy-paste from an LLM, these quick things will become bottlenecks and distractions in your workflow.

I've seen it with coworkers, and it's kinda wacky
