Before Docker, my FastAPI app only ran on my machine. Setting it up anywhere else meant installing Python, PostgreSQL, configuring ports, matching versions... With Docker, I reduced that to 2 commands: git clone ... docker compose up --build I containerized a FastAPI + PostgreSQL REST API covering users, products, and orders. The database and app run as isolated services that communicate through Docker's internal network. What I learned: Writing Dockerfiles Docker Compose for multi-container apps Container networking repo: https://lnkd.in/diy7H_Xh I also noted down every important Docker command I learned as a cheatsheet, might be useful if you're just starting out:https://lnkd.in/dchhqHkC #Docker #Python #FastAPI #Backend #Learning

Someone finally built a production-grade Agent OS in pure Rust. OpenFang isn't a Python wrapper or a generic multi-agent orchestrator. Here are the specs: → 137,728 lines of code. → 14 crates. → 1,767+ passing tests. → Zero clippy warnings. Because it's Rust, the performance metrics are insane. Cold starts happen in under 200ms. It uses just 40 MB of idle memory. It includes a SQLite memory backend with vector embeddings and canonical sessions. For me, this is what battle-tested infrastructure actually looks like.

Built a web-based network scanning tool using Python and Flask. It performs multi-threaded port scanning and shows results in a browser dashboard with live progress, scan history, and export options. I also added a simple risk analysis layer that gives a short explanation for each open port, along with basic safety controls to restrict unintended scans. Features: - Multi-threaded TCP scanning - Browser UI with real-time results - Scan history stored in SQLite - Export reports (TXT, JSON) - Safe mode for controlled usage GitHub: https://lnkd.in/gKDBtUs3

From a "Developer Script" to Standalone Software My first Python File Organizer worked great, but it had one major barrier: you needed Python installed and a terminal open just to run it. So I iterated. V2.0 transforms the same logic into a full-fledged application. Not just code anymore, a tool anyone can actually use. What's new:    1) Clean GUI built with Tkinter      2) Browse and select folders visually, no path typing required    3) Bundled into a standalone .exe with PyInstaller 450 mixed files. 7 clean folders. Done in seconds. A quick note on security:  Since this is an open-source and self-signed, Windows may display a SmartScreen warning. That's standard for apps without a paid code-signing certificate, not a red flag. I've documented how to bypass it safely (or run from source) in the README. The code and the release are live on GitHub - link in the comments. #Python #SoftwareEngineering #Automation #GUI #Tkinter #OpenSource

Day 27/100: Building My First Graphical User Interface (GUI)! Today was all about moving from the terminal to the desktop. I dived deep into Tkinter, Python’s built-in library for creating windowed applications. Key Technical Takeaways: Widget Management: Learning how to create and configure Labels, Buttons, and Entry fields. Layout Managers: Mastering the difference between pack(), place(), and grid() to position elements precisely. Event Listening: Connecting buttons to Python functions to make the app interactive. Project: Mile to Kilometers Converter: Developed a clean, functional desktop app that performs real-time unit conversions. It’s incredibly satisfying to build something that has a "Window" and a "Button" you can actually click. My Python scripts are starting to look like real software now!

We’re proud to be a sponsor at PyTexas Foundation 2026. If you're building modern Python apps, this hands-on lab is worth your time: Building a Full-Stack FastAPI App with open source DocumentDB via Docker You’ll build a full-stack app using FastAPI and open source DocumentDB, all running in Docker—focused on rapid prototyping, scalable APIs, and clean dev workflows. This one is very practical: containerized development, CI/CD patterns, and real-world debugging in reproducible environments. https://msft.it/6045Q7RZL #DocumentDB #Python #AzureDocumentDB

I have built my own HTTP server as a part of CodeCrafters challenge. Building a web server from scratch is one of those projects for a programmer that differentiates between using the internet and understanding how the internet actually works. Beyond just using APIs, this challenge helped me to understand sockets, binary data, and the HTTP protocol at a low level. You can read my blog around it here : https://lnkd.in/gn-sWv6w Github repo : https://lnkd.in/gXaC-VGZ CodeCrafters.io (YC S22) #Python #Programming

Weekly Project - 01 Project Name: Periodic Table of Elements Technology Used: Python, HTML, Javascript, Flask Live link in the comment box. Description: The web app displays all of the 118 elements of the Periodic Table with their names, electron numbers and atomic mass. This web app is particularly helpful for science students and science enthusiasts. I will actively add more details to the elements. If you want, you can add details to any elements on my Github repository. You can find the repo link at the bottom of the web app. If you like the project, consider hitting a star on GitHub. #python #webdevelopment #technology #science #periodictable

2-bit Qwen3.6-35B-A3B did a complete repo bug hunt with evidence, repro, fixes, tests and a PR writeup. 🔥 Run it locally in Unsloth Studio with just 13GB RAM. The 2-bit Qwen3.6 GGUF made 30+ tool calls, searched 20 sites and executed Python code. GitHub: https://lnkd.in/dcqhW9Vv GGUF: https://lnkd.in/gkG_a9vm Guide: https://lnkd.in/gWsiUmQh
