Rustlings VS Exercism - Scala Exercises

✅ Code Daily – Practice with small exercises (try Rustlings). ✅ Read the Official Book – Supplement with The Rust Programming Language. ✅ Join the Community – Engage on Rust’s Discord or forums. ✅ Build Projects – Apply concepts by creating CLI tools, web servers, or games.

Rustlings - Small exercises to get you used to reading and writing Rust code

Recently I got this obsession to learn Rust. While there are plenty of documentation around, like Rust Book, some good published books, tutorials, rustling, I always struggle to learn something when I am not doing something practical, so I have decided to go to my comfort zone and write a Kubernetes Controller using kube-rs.

Finish again the rustlings.

I’ve been meaning to do this for years, and just played around with rust a bit (liked it, but the wrappers around some c++ stuff i wanted to use were half baked). Learning rust, there was this “rustlings” thing [0] that was a set of guided exercises to go alongside the rust book. Fastest I’ve ever picked up a language, thanks to that. Do you or anyone know anything similar for c++?

Rustlings

It is becoming more and more applicapible to the Web... Servers and clients with #wasm, you can actually natively import a rust module into node.js for extra threads or heavy lifting. Start learning!

Practice with "Rust by Example" and "Rustlings"

Surprised no one has mentioned another great and similar resource called Rustlings [0] (yes very punny name). You are given some files with todo statements which you'll need to fix and make the code compile and pass all the tests. It's an interactive way to learn which is what got me through learning Rust a few years ago.

Zed is great, have been using it to do the Rustlings exercises and learn Rust:

The only thing left to do then was to build something that could showcase the power of code ingestion within a vector database, and it immediately clicked in my mind: "Why don't I ingest my entire codebase of solved Go exercises from Exercism?" That's how I created Code-RAGent, your friendly coding assistant based on your personal codebases and grounded in web search. It is built on top of GPT-4.1, powered by OpenAI, LinkUp, LlamaIndex, Qdrant, FastAPI and Streamlit. The building of this project was aimed at providing a reproducible and adaptable agent, that people can therefore customize based on their needs, and it was composed of three phases:

This is where sources like freeCodeCamp or Scrimba absolutely shine. With Odin, you read an article and may follow along with examples. But it’s unlikely you develop the muscle memory to implement the concepts on your own. Odin does offer some in-house exercises and often assigns external ones too. Still, I believe it’s not enough. You don’t lift weight only 5 times and say I’ve got this! You keep lifting until that muscle grows and continue lifting to keep it in shape. Similarly, you need to grow your mental muscles (brain neurons?) by doing many, many exercises. So you might want to augment your learning with other sources like Exercism or fCC.

If I get the time I would very much like to share my notes on adopting the various languages and perhaps even my solutions to some of the exercises. I have some reservations to doing the latter, since it does spoil the fun of solving the exercises for you. I have made some basic tooling which could be of interest/inspiration to you if you are in on Exercism.

I think you are looking for Exercism: https://exercism.org/

Great website!

Appeared at 2012. Built on top of BEAM to make Erlang\OTP runtime more accessible, because Erlang is not user friendly really; and shares the same abstractions and OTP framework for building distributed, fault-tolerant applications. Though initially designed with dynamic typing, Elixir is actively developing static typing capabilities cnrs. As Joe Armstrong said about types "no good type system save you from node failure" — that is why Erlang language was dynamically typed — it was not focus. And it is one of the two languages in this list available on Leetcode, but I would recommend to use https://exercism.org/ for practice firstly. You can think about this language as more modern and easy to use language for BEAM runtime than original Erlang language. Why does it matter? Because Erlang really powers high load. You can find out more here about real world use cases of Erlang its VM called BEAM. Whats-app cloud handles 2 millions connection per a node for instance. It is simple language nevertheless a powerful one. Maybe Elixir has not really good theoretical fundament, but it is still good language and its author José Valim actively works on bringing type system with synergy of academic world.

Work has eaten up most of my spare time lately, or it hasn't left me with much energy that I could devote to additional learning. I've gone quite a few day without any studying. Today, I've managed to complete a few challenges on Exercismthat were left open and I'm about to get back to studying for the CompTIA Project+ certification.

Mentored six students on (https://exercism.org/). Got one testimonial (positive). Have received a total of five so far, all good words.. I've mentored a lot more students in total, but the sessions are not counted until they acknowledge feedback and terminate them. Some submit requests for mentoring but then forget about them, which is frustrating, considering I put a lot of time and effort into giving proper feedback.

Although I was initially afraid of mentoring (on Exercism), I seem to have fallen into a positive flow. It's been a great feeling to help students who have just recently started out on their journey. I was able to spot bits and pieces susceptible of improvement and steer them in the direction of better habits and best practices. It's only been a few days, but I feel I've already grown a lot from it, and I'm grateful for the opportunity. The (positive) pressure is also pushing me to strengthen and expand my own knowledge. It keeps me on my toes and helps me not to become stagnant and complacent. I've already received positive feedback from some students and I look forward to mentoring more.
