Ruby is the most cost-efficient and stable language for Claude Code! Followed closely by JavaScript and Python. An experiment by Yusuke Endoh was published - https://lnkd.in/dpzV_-Ep The task for Claude Code was simple. Implement a simplified version of Git. A total of 13 programming languages participated in the experiment. Ruby turned out to be the winner - the fastest, cheapest, and most reliable language in this benchmark. That said, Python and JavaScript were very close to Ruby in the results. A few observations from the experiment. 1. Dynamic vs static typing Claude Code performed worse with statically typed languages than with dynamically typed ones. At least in this specific experiment. It would be interesting to see whether the results change for large production-style projects where type safety plays a bigger role. 2. Ruby in the AI era Ruby is sometimes described as a relatively low-resource language (there is less open-source code available compared to some other langs). Despite that, it performed extremely well in this experiment. Ruby is strong choice in the AI era. 3. The gap is small The metrics for Python and JavaScript are very close to Ruby. The difference might not be that significant in the long run, especially considering the massive growth and open-source ecosystems around those languages.

1,076 commits in TypeScript. 635 commits in Python. Same team. Same product. Same year. --- I work on two completely different backends every day. Morning: TypeScript + NestJS — the platform that lets teams at Deel build Slack apps. Afternoon: Python + Django — the legacy backend with 9 running plugins, real users, live data. When I started, switching between them felt like context-switching between two jobs. Now it doesn't. Here's what changed: I stopped thinking in languages. I started thinking in patterns. Dependency injection in NestJS? Same concept as Django's middleware pipeline. Sequelize migrations? Same mental model as Django ORM — just different syntax. NATS consumers? Same pub/sub pattern you'd implement in any event-driven system. The patterns don't care what language you're in. They care about the problem you're solving. Once I understood that — really understood it — switching stacks became as natural as switching between different parts of the same system. Because that's exactly what it is. AI tools helped accelerate this. Not by writing the code — but by letting me ask questions across contexts. "Explain how Django's middleware chain works" when I haven't touched it in two weeks. "Trace this NATS consumer from event to handler" before I start debugging. The pattern is the same in both stacks. AI helps me find it faster. The most dangerous label in engineering: "I'm a [language] developer." It limits what you'll pick up. It limits what you'll contribute to. It limits what you'll learn. Your stack is a tool. The problem is the job. What's a pattern you learned in one stack that completely changed how you think in another? #BackendEngineering #SoftwareEngineering #Python #TypeScript #CareerGrowth

🚀 From Backend APIs to Smart Automation with Core Python A few days ago, I shared my Streamlit Password Generator project. Today, I’m excited to share another project I built using Core Python + Streamlit — a Smart File Organizer. As a backend engineer with 4+ years in PHP/Laravel and Django, I’ve spent most of my career building APIs, payment systems, and transaction-heavy platforms. But recently, I decided to go deeper into core Python fundamentals — not just frameworks. So I built something simple… but powerful. 🧠 The Problem: We all have messy folders filled with random files: Images (.png, .jpg, .jpeg) Documents (.pdf, .docx, .txt) Videos Audio files And “mystery files” 😅 🛠 The Solution: A Smart File Organizer that: • Accepts a folder path • Scans all files • Detects file extensions • Automatically groups them into folders like: Images Documents Videos Audio Others Built with: Core Python (os, shutil, file handling) Streamlit (for a clean interactive UI) 💡 What I Loved About This Project Seeing how powerful Python’s standard library is Writing logic without depending on heavy frameworks Turning backend logic into a usable interface with Streamlit Building something practical that solves a real everyday problem What’s interesting is this: As a backend developer used to Django and Laravel, this experience reminded me that strong fundamentals > frameworks. Frameworks are tools. Core language knowledge is power. I’m really enjoying this phase of building small but practical tools with Python. More projects coming soon 🚀 #Python #Streamlit #BackendDeveloper #SoftwareEngineering #BuildInPublic #LearningJourney #WomenInTech

A Ruby developer just benchmarked 13 programming languages with Claude Code to find which works best for AI agents. The results might surprise you. The study on GitHub (https://lnkd.in/e-g_cYCZ) tested how well Claude Code performs across different languages, from Ruby and Python to Go and Rust. What's fascinating is that this isn't about raw performance or syntax elegance. It's about which languages let AI agents understand context, navigate codebases, and generate working solutions most effectively. Here are the 3 key factors that emerged: 1. Error message clarity, Languages with descriptive compiler errors (like Rust) let Claude self-correct faster than cryptic runtime failures in dynamic languages. 2. Standard library discoverability, Python and Ruby score high because their stdlib methods have predictable names that align with how developers (and AI) think about problems. 3. Ecosystem conventions, Languages with strong idioms and consistent project structures give Claude better contextual clues about what you're trying to build. I found this really interesting, and I'm curious to see how results like this will fuel future approaches for new technologies.

Python is an easy choice. Deciding between Flask and Django is where it gets messy. Flask gives you a lightweight, flexible core you can shape however you want. Django arrives with batteries included: ORM, admin, auth, and a strong “this is how we build” philosophy. In this guide from AppMakers USA, Aaron Gordon compares Flask vs Django across project size, team structure, performance, ecosystem, and long-term maintenance—plus where each framework has worked well in real-world products. If you’re planning a new web app, SaaS product, or internal tool in Python, this will help you pick a framework that matches your reality instead of guessing. 👉 Read the full article here: https://lnkd.in/gRFrc3TU #Flask #Django #Python #WebDevelopment #AppMakersUSA

Here's a thing I'm noticing from porting TypeScript solutions into Python: The bugs cluster. They're not random. I keep hitting the same five or six friction points, and they're all places where TypeScript gave me a habit that Python doesn't want. The sum built-in shadowing thing has gotten me twice now. It's a free variable name in TypeScript. In Python, it's a loaded word, and the failure is silent. The interpreter doesn't warn you. Your code runs. It produces wrong answers. I also keep writing @dataclass with nobody. TypeScript lets you declare an empty class. Python wants at least a pass. This one's quick to fix, but I have to fix it every time because my fingers don't believe it yet. The interesting part, for me, is that I know every one of these rules. I've known them for a while. Knowing hasn't made them automatic. I still pause, correct, and move on. The pause is the whole problem. I'm curious whether this ever fully goes away for people who work in two languages daily, or if there's always a context-switch tax.
