Curated signals for developers. Updated hourly.
Three problems that look unrelated: A vibration sensor on a motor gives you a jittery reading every second. You want to know the actual wear on the bearing inside, which you can't measure directly. An AI agent has a long conversation with a user. It
I have a teammate who never sleeps, never gets bored, and spends every hour poking at our app trying to break it. It is an agent. Every hour it opens the real app, clicks around like a tester would, and files a bug report for anything that looks off.
This is a submission for the DEV Weekend Challenge: Passion Edition . What I Built My passion is not a hobby. It is not a sports team. It is a deep, principled, load-bearing hatred of LeetCode and the interview-industrial complex it represents. The c
Picture the human at the end of an agent pipeline. The agent drafts an action. A modal pops up. Approve or reject. The human has seen forty of these today, they all looked fine, and the queue is backing up. They click approve. They will click approve
If you've ever shipped a mobile app to a client, tester, or QA team, you've probably used Diawi. It's been the default answer to "how do I get this APK/IPA onto someone's phone without going through the App Store or Play Store" for years. I used it t
A frontend can look stable while becoming much harder to test. The main user journey may still work. The login button is clickable, the checkout completes, and the dashboard loads. Yet underneath that apparently healthy flow, the application may have
Most browser tests are described as sequences of actions: open a page; click a control; enter some text; submit; verify the result. That description makes automation sound straightforward. In real applications, however, the difficult part is rarely t
Use this maturity model to assess your design system’s health and identify where to focus next.
Let's be real, OpenAI isn't giving up on the browser market, it is just changing its strategy.
Six years in prison for man who "sold out the very victims he was hired to represent."
China lands its first Long March-10B rocket booster, advancing reusable launch tech and intensifying the U.S.–China space race.
How I Supervise Three Engineering Workflows at Once Three Workflows, One Operator Right now, I have three engineering workflows open. One is under council review. Four AI roles are challenging an architectural proposal, and I will need to decide whic
I have a confession to make. When I first saw that Tether-the behemoth behind the $110 billion USDT stablecoin-was the primary financial backer of Holepunch, Keet, and the Bare JavaScript runtime, my brain short-circuited. I struggled with the cognit
Learn TypeScript From First Principles to Senior/Staff-Level Production Engineering If you searched for how to learn TypeScript properly - not just the syntax, but the thinking behind it - this guide is built for that. Most TypeScript tutorials stop
Last month I watched Cursor confidently rename a field across an entire API, commit it, and open a PR. Clean diff, tests green, looked great. It had also just broken a mobile client and a partner integration that were still reading the old field name
Stop Writing Prompt Strings: Meet PromptForge Core As AI becomes part of modern applications, prompts are no longer just strings-they're becoming part of your codebase . Yet most of us still write prompts like this: const prompt = " You are a helpful
A year and a half ago, I wasn't trying to build an AI company. I was building a small social platform called spritex-social - nothing fancy, just a side project a handful of friends were testing with me. No grand plan, no investors, no roadmap beyond
AI coding agents are now part of the developer workflow. Whether we like that shift or hate it, users ask Codex, Cursor, Claude Code, GitHub Copilot, and other tools to install packages, wire examples, migrate code, and explain APIs. For JavaScript d
Last time I wrote about splitting Claude Code's memory into four layers . This is the follow-up: a setup where Claude Code itself discovers "reusable procedures" and accumulates them as skills over time. After running this for a few months, ~/.claude
Evening. My Claude subscription refills its quotas. Most days they evaporate the way everyone's do - autocomplete, small refactors, a summary here and there. This is a worklog about one day with Fable. And in a way I did not expect, it was touching.
TL;DR - A hand-written AGENTS.md rots the day you write it. And unlike a stale README (which a human skims skeptically), a stale AGENTS.md is obeyed by your coding agent with full confidence: wrong build command, missing guardrail, dead convention -
Researchers at firmware security firm Binarly have found six new flaws in U-Boot, the small program that starts up hardware as varied as home routers, smart cameras, and the management chips inside data-center servers. Four of the bugs can crash a de
Unknown threat actors compromised the Injective Labs SDK project's GitHub repository and leveraged it to publish a malicious package on the npm registry to steal cryptocurrency wallet private keys and mnemonic seed phrases. The compromised version, @
SK hynix, TetraMem, and the University of Southern California built a memristor-based in-memory computing system-on-chip for AI edge devices, achieving promising energy efficiency, but failed to demonstrate its full potential.
HyperTexting's new app aims to make the open web feel more like social media by turning websites, blogs, newsletters, and podcasts into a scrollable feed, while also making it easier to post to your own website.
