    Project mention: Good coding groups for black women? | news.ycombinator.com | 2024-01-13

  • TheAlgorithms

    All Algorithms implemented in Python

    Project mention: Wikifunctions | news.ycombinator.com | 2023-12-06

    Is it me or does it not seem very well thought out? Every example I've seen only has implementations in JavaScript and/or Python. I haven't seen any other languages nor a way to search by language. What a "string" means in one language can be completely different in another language. The primitive data types that the project assumes are not really supported across all programming languages.

    Also if anyone hasn't already seen them, similar projects already exist and are more complete. E.g.

    * https://rosettacode.org/

    * https://programming-idioms.org/

    * https://the-algorithms.com/

    Not to mention LeetCode, CodeWars, Project Euler, Exercism can kinda serve the same role.

  • Windows Terminal

    The new Windows Terminal and the original Windows console host, all in the same place!

    Project mention: Windows 11 looks to be getting a key Linux tool added in the future | news.ycombinator.com | 2024-02-02

    "Users of Linux and macOS may well be familiar with the sudo command, used regularly in the terminal, and it looks like Windows may finally be getting its own version."

    More Linux tools are coming to Windows, especially Windows Server because the tools are good and they make it easier to administer a Windows Server.

    They are looking at adding a default TUI text editor (https://github.com/microsoft/terminal/discussions/16440) and now they are adding sudo.

    I would not be surprised if systemd or something like it gets ported or reinvented for Windows simply because it makes managing services so nice.

  • Material UI

    Project mention: Zero-runtime CSS-in-JS implementation | news.ycombinator.com | 2024-01-29
  • rust

    Empowering everyone to build reliable and efficient software.

    Project mention: Delving Deeper: Enriching Microservices with Golang with CloudWeGo | dev.to | 2024-02-22

    Built for the modern development landscape by embracing both Golang and Rust, CloudWeGo delivers advanced features and excellent performance metrics. As proof of its performance, benchmark tests have shown that Kitex surpasses gRPC by over 4 times in terms of QPS and latency, with a throughput increased by 51% - 70% in terms of QPS (Queries Per Second) and latency.

  • Design Patterns

    Design patterns implemented in Java

    Project mention: I have been following the mooc java-1 from few days and i am on part-3 i want to ask some questions | /r/learnjava | 2023-06-06

    After that, more practice, and then Design Patterns (as in the famous book of the "Gang of Four": "Design Patterns: Elements of Reusable Object Oriented Software"). Here I'd recommend "Head First: Design Patterns" and Java Design Patterns as well as Refactoring Guru (the sites are more reference than course).

  • Godot

    Godot Engine – Multi-platform 2D and 3D game engine

    Project mention: Ask HN: Yo wants to build a game, I'm lost. What can I do? | news.ycombinator.com | 2024-01-17

    Godot [1] is a very nice game engine. There's a game on Itch.io that teaches the scripting language it uses [2], and a ton of great tutorials on YouTube for beginners and experts alike.

  • excalidraw

    Virtual whiteboard for sketching hand-drawn like diagrams

    Project mention: Ask HN: Anyone use a code to mindmap/flowchart tool? | news.ycombinator.com | 2024-02-24

    I was happy to find out recently that there is a way to make Mermaid diagrams WYSIWYG / drag and drop editable that the open source https://excalidraw.com has and did I mention it's open source!? With a LLM, you can go full loop back to Mermaid again after a few rounds of manual editing. "What a time to be alive!"

  • Home Assistant

    Project mention: Ask HN: Why is it so difficult to control IoT devices from your desktop? | news.ycombinator.com | 2024-02-22
  • github-readme-stats

    :zap: Dynamically generated stats for your github readmes

    Project mention: How to over engineer your protfolio site | dev.to | 2024-01-14

    All that is standard , let's compound this process by adding programming language stats . There's a project on github that we can embed directly into our markdown or html , but we want more so i made a recursive function to fetch all our repositories (The github readme script only fetches the first 100 repos)

  • Nest

    A progressive Node.js framework for building efficient, scalable, and enterprise-grade server-side applications with TypeScript/JavaScript 🚀

    Project mention: Rust GraphQL APIs for NodeJS Developers: Introduction | dev.to | 2024-02-08

    In my usual NodeJS tech stack, which includes GraphQL, NestJS, SQL (predominantly PostgreSQL with MikroORM), I encountered these limitations. To overcome them, I've developed a new stack utilizing Rust, which still offers some ease of development:

  • 33-js-concepts

    📜 33 JavaScript concepts every developer should know.

    Project mention: JavaScript concepts every developer should know | news.ycombinator.com | 2024-01-11
  • Ansible

    Ansible is a radically simple IT automation platform that makes your applications and systems easier to deploy and maintain. Automate everything from code deployment to network configuration to cloud management, in a language that approaches plain English, using SSH, with no agents to install on remote systems. https://docs.ansible.com.

    Project mention: Interesting Uses of Ansible's ternary filter | news.ycombinator.com | 2024-02-22

    They support for-if from python, too: https://jinja.palletsprojects.com/en/3.1.x/templates/#loop-f... but I haven't tried the "recursive" keyword to know if ansible supports that. I say "ansible supports that" because they don't just drop jinja2 into ansible and call it a draw, they have a bunch of custom execution integrations: https://github.com/ansible/ansible/blob/v2.16.3/lib/ansible/...

  • Grafana

    The open and composable observability and data visualization platform. Visualize metrics, logs, and traces from multiple sources like Prometheus, Loki, Elasticsearch, InfluxDB, Postgres and many more.
