Building FastAPI App with DocumentDB via Docker

Checking Codeforces, then AtCoder, then LeetCode just to keep track of contests is a productivity killer. So I built CPAgent. It fetches upcoming contests from Codeforces, AtCoder, LeetCode, and CodeChef every day and syncs them straight to Google Calendar. Correct timezone. No duplicates. No manual effort. Built with Python 3.10, Pydantic v2, and the Google Calendar API. Repo is live and open source. 🔗 GitHub: https://lnkd.in/g7JxU8g3 #OpenSource #Python #CompetitiveProgramming #Automation #GitHubActions

Most LangChain apps should just be 40 lines of raw API calls. I've refactored three production LangChain projects this year. Every time, ripping out the framework cut latency, halved the debugging time, and made the code readable again. Chains, runnables, callback handlers - layers that exist to manage complexity they created. If your agent fits in one file, you don't need an orchestration framework. You need httpx and a system prompt. Tell me I'm wrong. #langchain #llm #python

The low code/ no code ecosystem that thrived for the last 20 years is dying as architecture. The idea of building a custom proprietary runtime that only works for specific vendor is no longer a solution. Now you can generate apps of javascript, C#, Python,….. using new generation of platforms that are not proprietary. It helps you generate the code not own your app through monthly subscription forever. Even if the old platforms added AI generators, why sticking to proprietary if I can be free? That’s the challenge for platforms like Power Apps. Either to start new from scratch or lose the market. #nocode #lowcode #powerapps

🚀 AlgoArena is LIVE. 5 days ago this was just an idea. Today it's a deployed, fully functional web app accessible by anyone in the world. AlgoArena tracks your DSA practice and tells you: → Your current streak 🔥 → Your weakest topics ⚠️ → Your solve rate by topic and difficulty → Your full problem history with filters Built with Python, Flask, SQLite. 🔗 Live: https://lnkd.in/gsAgXF53 💻 GitHub: https://lnkd.in/gN697DNY This is what 5 days of building in public looks like. 🛠️ #buildinpublic #python #flask #webdevelopment #dsagrind #studentdeveloper #softwareengineering

🚀 Implementing Idempotent API Endpoints in Python with Flask (System Design) This example demonstrates how to create an idempotent API endpoint using Flask and a simple in-memory store. The API expects an `idempotency_key` in the request header. It checks if a request with the same key has already been processed. If so, it returns the previous response. Otherwise, it processes the request and stores the response along with the key. This ensures that duplicate requests are handled correctly, preventing unintended side effects and ensuring reliability.

🚀 Turning Spaces into URLs — Another Small Win! Today I solved a basic but practical problem on GeeksforGeeks: URLify a string — replacing spaces with "%20". This is actually something used in real-world applications like web development and URL encoding. It made me realize how even simple DSA problems connect to real use cases. I used a clean and efficient approach with Python’s built-in function: 👉 replace() — simple, readable, and powerful. ✅ All test cases passed ✅ Clean one-line solution ✅ Real-world relevance ⏱ Time Complexity: O(n) 💾 Space Complexity: O(n) Sometimes the best solutions are not the most complex ones, but the most elegant ones. Small steps. Daily progress. Strong foundations 💪 How would you solve this — built-in function or manual approach? 🤔 #python #dsa #coding #programming #geeksforgeeks #strings #webdevelopment #developers #learning #100daysofcode

This app helps with learning French words by showing a word on a card, then flipping it after 3 seconds to reveal the English meaning. You can mark words as known, and the app keeps track of your progress by saving only the words you still need to learn.

Write portable plugins that run natively or in the browser using Python, Rust, C#, and more! 🐍🦀 https://www.fslabs.ca/sdk The Foresight Development Kit is shipping support for runtime extensions later this year. Write application code once, and automatically generate WASM and gRPC bindings. You can distribute these bindings to build your own internal or external extension ecosystem. This video shows identical extensions written in Python and Rust running in the browser!

Just released Prism — a lightweight, self-hosted web app that provides a single, unified interface to post across multiple social media platforms simultaneously. Built with #FastAPI and #Python, it’s designed for those who want to stay active on both Bluesky and Mastodon without the double effort. Check it out: https://lnkd.in/eVe_shEZ
