Originally published on the Cosmic blog. Bun v1.3 is the fastest JavaScript runtime you can use right now. Cosmic's REST API returns content in under 100ms. Put them together and you get a full-stack setup that's faster at every layer: cold starts, package installation, HTTP requests, and content de
Published: May 30, 2026 Tags: ai, agents, opensource, github, bounty, tutorial, python, architecture Every week, someone tweets "I built an AI agent that makes money while I sleep." And every week, the replies are the same: prove it. So I did. I built ZKA (Zero Knowledge Agent) — an autonomous AI ag
Why the obvious approach crashes, and how a few generator functions keep memory flat no matter how big the file gets. A while back I had to do something that looked trivial on paper. Read a CSV export, filter the rows we cared about, sum one column, write a small report. The kind of thing you bang o
How to use AI in your development workflow without losing your edge Integrating AI Into Daily Development: A Practical Workflow Start with the Right Mindset Treat AI as a junior developer with exceptional recall but limited context. Your value shifts from writing code to exercising engineering judgm
Hey dev.to community 👋 Over the past few days, I’ve been running dozens of AI Agent experiments. The more powerful they got, the more nervous I became. They can do amazing things, but they’re also shockingly easy to jailbreak, abuse tools, or quietly exfiltrate data. And once they go rogue? Traditi
Network requests fail. Timeouts happen. Clients retry. And without idempotency keys, a single payment request can become three charges. Idempotency keys are one of those API patterns that's easy to overlook until something goes wrong in production. Here's how they work, when to use them, and how to

في قلب كل ابتكار عظيم تكمن قصة إنسانية ملهمة، قصة شغف وتحديات وإصرار لا يلين. هذا هو جوهر رحلة فريق "المستوصف"، الذي بدأ كفكرة مشروع تخرج طموحة وتحول إلى نظام مراقبة صحية ذكي يعد بثورة في الرعاية الصحية بمصر. الشرارة الأولى: حلم يتجاوز حدود الدراسة لم يكن "المستوصف" مجرد مشروع تخرج عادي لستة طلاب هن
Every morning, I found myself onboarding a new AI agent. Not a new human teammate. The pattern was always the same: I would open a fresh session and say something like: Continue the bug I was debugging this morning. And the agent would basically ask: What bug? What files? What changed? What failed?
How to approach hard problems — first principles thinking for engineers First principles thinking is a powerful engineering method for solving hard problems by stripping away assumptions, reducing a system to fundamental truths, and reasoning back up to a solution from those truths. In practice, it
My first day at a real software engineering job. I opened the codebase. Twenty thousand lines of code. Then my manager sent me a ticket: "Customers are complaining that premium That was it. No hints. Just me. And someone else's mess. I had passed every LeetCode problem None of it prepared me for thi
Hello Dev Community 👋 I recently built my first web project called Namastra — a simple tool to explore the meanings, origins, and insights behind names. 👉 Live Demo: 💡 Why I built this I noticed that many people are curious about: What their name means Where their name comes from What personality
Bun is fast. The README will tell you 4x on bun install, 3-5x on Bun.serve(), 2x on bun:sqlite. Some of this matters for AI agents. Some of it doesn't. We've been running production agents on Bun for about 3 months — a mix of Hono-on-Bun HTTP agents and standalone Bun scripts called from Claude Code
Overview We built the Ota skill because too much "AI repo automation" is still fake confidence. An agent clones a repo, finds a plausible command, edits the right file, and looks smart right up until it does something expensive and stupid. It runs the wrong test path. It installs tools globally beca
This is a submission for the GitHub Finish-Up-A-Thon Challenge A year ago, I built a project called Focus Forge Agent. At that time, it was just another late-night idea that turned into a GitHub repository. Like many student developers, I started the project with huge excitement, ambitious plans, an
Everyone is collecting prompts. The people getting real results are building something else. Over the holidays last year, something shifted in how I use Claude Code. For months I had treated it like a very smart autocomplete. Open the terminal, type a request, read the answer, repeat. It worked. I s
Choosing an open source PostgreSQL operator for Kubernetes used to be a question about features and community size. In 2026, it has become a question about licensing posture, image distribution, and whether the project you pick today will still be operationally open in three years. MinIO is archived
Microservices have become the default recommendation for modern software architecture. Ask a group of developers how they would build a new SaaS platform, and chances are someone will suggest: Microservices Kubernetes Event-driven architecture Service mesh Distributed tracing But here's the question
I once spent half a day debugging code that was completely correct. The problem wasn't the logic. The problem was that the functions the LLM had written didn't exist. Not deprecated. Not renamed. Never existed. Here's what had happened: I caught the model using an outdated API parameter and correcte
Software development sounds pretty straightforward at first, right? Build the product, test it, and deliver it. Done. But here's the thing — in reality, things rarely go exactly as planned. Requirements change midway through development, new ideas pop up unexpectedly, deadlines shift, customer expec
