How I Built an Autonomous AI Agent That Earns USDC While I Sleep A pragmatic walk‑through for developers who want to experiment with paid micro‑services on‑chain. 1. Why bother with an “earning while you sleep” agent? The idea is simple: expose a tiny, useful function (e.g., “return
When I started building a grounded RAG system over FHIR records, I assumed the hard part would be retrieval and generation. Two years of working with FHIR had made the resource model familiar, but that familiarity turned out to be the easy half. The real question was which parts of the FHIR structur
A team I know had green backup alerts for six months straight. Every day, the backups completed. Snapshots were being created on schedule. Retention was configured. Monitoring was quiet. As far as everyone could tell, the database was protected. Then one day, they needed to restore it. The snap
The Complete Guide to Agent-to-Agent Marketplaces in 2026 In 2026, the primary consumers of web APIs are no longer human-facing frontend applications. They are autonomous AI agents. When Agent $A$ needs to solve a sub-task outside its domain—such as verifying a zk-proof, deep-scanning a smart co
What Is FastAPI FastAPI is a modern, high-performance web framework for building APIs with Python. It helps developers create backend services quickly while keeping the code clean, reliable, and easy to maintain. An API (Application Programming Interface) allows different software applications to
The Fatal Dual-Write Problem As your enterprise backend evolves from a monolithic application into a distributed microservices architecture, you inevitably encounter the most dangerous data integrity issue in distributed systems: the Dual-Write Problem. Imagine an e-commerce platform where the "O
Short answer: verify JWT signatures locally with a cached JWKS, but require live session introspection at the API gateway for refresh-token rotation, stolen-session revocation, and other account-continuity decisions where a valid signature is not a sufficient authorization signal. Keep those boundar
been the only dev on a backend service for about two years. finally sat down to write proper docs for it today. found a try/except block in the job queue handler. catches one very specific exception type. does absolutely nothing with it -- no log, no reraise, no fallback. just silences it. there's n
You got sandwiched. Your swap landed between a searcher's buy and their sell, you paid for it, and every receipt you can pull agrees that you were robbed. None of them can prove the order it happened in. That is the strange gap this post is about. A transaction receipt carries the block number, the
In the fintech sector, data integrity and system reliability are paramount. When managing sensitive operations such as credit products, loan disbursements, or transaction processing, message loss or system timeouts are not merely technical incidents; they represent critical operational risks that ca
One of the biggest challenges Rust developers report in our annual surveys is a subpar debugging experience. So, back in February, we ran our first Rust Debugging Survey, in the hopes of identifying how Rust developers are using debuggers and what problems they are facing when doing so. We received
This is a submission for Weekend Challenge: Generosity Edition What I Built Andrea has been waiting 174 days for someone to reply to his issue. He asked nicely. He labelled it help wanted. Someone who knows Rust could answer him tonight in ten minutes. They just don't know he asked. Th
My side project, PD.Radar, ranks resources mentioned in big Ask HN threads by citations (distinct commenters naming the thing), not by upvotes. Upvotes measure drama; citations measure how many people independently bothered to name the same resource. The site went live with one leaderboard: 540 com
Every service I self-host sits behind one front door: Authelia, doing single sign-on and 2FA for the lot — the dashboard, the password vault, the VPN control plane, a couple of internal tools, the monitoring. One login, one place to enforce a policy, one place to revoke access. When people say "secu
Originally published at nlocoding.com 57 million lines. That’s how much code Google maintains across its repositories as of 2026 (GitHub Octoverse, 2026). And no, it doesn’t crash every Friday. AI is quietly saving them millions. AI solutions for managing large codebases are not a luxury in 202
The system still runs the business. It is also on a version nobody supports, two people understand it, and the quote you got for replacing it came with the phrase feature parity and a timeline in years. This page is written from your side of that quote. What modernization actually covers, why the qu
FaceVision does face detection, recognition and liveness checks without sending a single frame to a server, because every model runs in the browser through ONNX Runtime Web. That architecture is the reason its privacy story is simple. It is also the part students find hardest to get working, so here
Introduction In control flow operations—such as jumps (jmp), branch instructions, and function calls (call)—the distinction between CISC and RISC architectures becomes immediately visible. In a variable-length CISC architecture like x86, the processor can encode absolute 32-bit addresses directly
Una nota personale Nel 2000 lavoravo principalmente su Windows NT — stavo pure prendendo una certificazione — quando mi hanno assegnato a un nuovo progetto che doveva collegarsi a server Unix. Il mio collega, in affiancamento, mi dice: "apri il terminale, PuTTY". Io, tranquillo, doppio click sull'
One task, one concern, one or two files, one test, one command. The rule I use to know when to stop splitting isn't a line count - it's whether anything still has to be looked up. 👋 I'm Anton - a software engineer working mostly in PHP/Symfony and Go, currently carving a live PHP monolith into G
