🦀 Microsoft just open-sourced a comprehensive Rust training curriculum and it's impressive. The microsoft/RustTraining repository on GitHub offers 7 structured books covering Rust from beginner to expert level, designed for developers coming from different backgrounds: 🟢 Bridge Books (start here): • Rust for C/C++ Programmers • Rust for C# Programmers • Rust for Python Programmers 🔵 Deep Dive: Async Rust (Tokio, streams, cancellation) 🟡 Advanced: Rust Patterns (Pin, allocators, lock-free structures) 🟣 Expert: Type-Driven Correctness (type-state, phantom types) 🟤 Practices: Rust Engineering (CI/CD, cross-compilation, Miri) Each book includes 15–16 chapters, Mermaid diagrams, interactive Rust playgrounds, and exercises. Whether you're a systems programmer migrating from C++, a .NET developer exploring performance-critical code, or a Pythonista tired of the GIL, there's a path for you. ⭐ Already at 500+ stars. Fully open source (MIT + CC-BY-SA-4.0). 👉 github.com/microsoft/Rust… Rust is becoming a serious part of the industry stack. If you've been waiting for a structured way to learn it, this might be it. #Rust #Programming #OpenSource #Microsoft #SoftwareEngineering #SystemsProgramming #Learning

Master containerd the hard way (free course) 😤 Assembling a system from scratch is a well-known learning trick to take your understanding to a different level. Most DevOps folks likely heard about the Kubernetes the hard way tutorial. But Kubernetes is not the only tech that can be learn this way! containerd is the most widely used "mid-level" container runtime. Both Docker and Kubernetes rely on it under the hood to run and manage containers. Learning about the key moving parts of containerd, how to install and configure them, and how to use containerd directly from the command line will help you deepen your understanding of containers in general and the higher-level runtimes like Docker and Kubernetes in particular, improving your system design and troubleshooting skills.

Networking 101: Connect two private networks with a router 🛠️ An easy one today - it's Friday after all. Can you configure a Linux VM to serve as a simple router between two disjoint private networks? Learning networking by doing 👉 labs.iximiuz.com/challenges/net…

Docker 101: Building Container Images 🐳 I prepared a skill path that helps you learn Dockerfile authoring from the ground up, starting with the simplest possible image and building up to production-grade multi-stage builds. You'll learn how to: - Build and publish a container image to a registry - Write Dockerfiles using core instructions: FROM, COPY, RUN, and CMD - Handle application and system-level dependencies in a Dockerfile - Compile and build applications inside a Dockerfile - Inspect container image internals (layers, sizes, digests) - Optimize images with multi-stage builds to produce smaller, cleaner production artifacts By the end of this skill path, you'll be comfortable writing Dockerfiles for real-world applications and understand how to keep your images lean and efficient. Happy building! 🛠️ labs.iximiuz.com/skill-paths/do…

Building images with Docker - from Zero to Hero 🐳 Prepared a batch of hands-on problems that start from writing your very first Dockerfile and gradually walk you all the way up to using multi-stage builds for more optimal images: - Write Your First Dockerfile labs.iximiuz.com/challenges/doc… - Write a Dockerfile for a Simple Web Server Application labs.iximiuz.com/challenges/doc… - Write a Dockerfile That Excludes Dev Dependencies from the Production Image labs.iximiuz.com/challenges/doc… - Write a Dockerfile for an Application With System-Level Dependencies labs.iximiuz.com/challenges/doc… - Build and Compile Applications in Dockerfiles labs.iximiuz.com/challenges/doc… - Build and Inspect a Container Image With Docker labs.iximiuz.com/challenges/doc… - Optimize Container Images with Multi-Stage Builds labs.iximiuz.com/challenges/doc… Happy building! 🛠️

The movement of the radioactive cloud after the Chernobyl disaster

Can you protect an unintentionally exposed server port using a firewall? Obviously, it shouldn't have happened in the first place, but it did. Now you have a problem at hand and no means to actually restart the service with the right config. Have fun: labs.iximiuz.com/challenges/lin…

Algorithmic plants / L-systems in AR @threejs @Spectacles

We take randomness for granted. Early PRNGs were BAD. Thousands of scientific papers used to rely on RANDU, created by IBM in the 1960s. In 1D space, it looks ok! Map in 3D…you start to see the issues. Now, there *was* a better solution...but it would cost you.
