OpenAI has parted ways with three safety researchers after an internal investigation found they mishandled sensitive company information, report says.

Fervo Energy completed its first power plant in less than two years. The next phases promise to connect to the grid even quicker.

Google launched its first advanced chip into orbit to pave the way for space data centers.

OpenAI is rolling out new shopping features for ChatGPT that let users virtually try on clothing and accessories using their own photos and save products they like to a Favorites library.

What this is about Learning cloud and DevOps has a cost problem. The tools are paid, the infrastructure bills by the hour, and the good courses sit behind subscriptions. Plenty of people learn the concepts and never get to use the professional tooling that goes with them. The GitHub Student Developer Pack takes much of that cost away while you're a verified student. I have it, I use part of it, and this post covers what's in it, how I'd pick from it as someone building toward Cloud/DevO...

The awkward edge case in a consumer wallet flow is the first transaction: the user has the asset your application needs, but none of the chain’s native token. Asking them to visit an exchange or bridge before they can use the app is technically honest and often terrible UX. Account abstraction offers another option. A paymaster can cover the network fee while the user’s assets remain in their own smart account. That removes one prerequisite, but it also introduces a sponsor with policy contro...

The problem: agents invent APIs I've been building CMS software for web designers since 2015. This year I started building with coding agents every day, and I kept hitting the same failure. I'd ask an agent to add a section to a site, and it would confidently write a template that called a function that didn't exist. Plausible name, plausible arguments, wrong. Sometimes it came from an older version. Sometimes it was invented whole. The code looked right, and that was the problem. A br...

Let’s talk about P vs NP—the single most important unsolved problem in theoretical computer science, a Clay Mathematics Institute Millennium Prize Problem, and a question with a $1,000,000 bounty on its head. At its core, the problem boils down to a strikingly simple question: If it is easy to CHECK that a solution to a problem is correct, is it also easy to FIND that solution from scratch? Let’s break this down from first principles with zero fluff. The Core Definitions Theoretica...

How a fully sovereign QA stack — local Wikipedia index, distilled Qwen2.5-3B reader, and crutches built only from measured failures — went from 33% to 52% on facts no LLM can have memorized, and matched a zero-shot 7B more than twice its size. TL;DR Configuration Post-cutoff-150 accuracy 3B naked (no retrieval) 0.0% [0–2.5] 7B naked 0.0% (by construction — see below) 3B + sovereign chain (start, Sep 29) 33.3% 3B + sovereign cha...

Cucumber earns its place on one kind of test: an acceptance test whose output someone outside the development team reads. A tester, an analyst, a product owner. That reader is the only reason to put Given-When-Then on a test at all. Unit tests are code, and developers can read code. I wrote Kensa for that reader, and it works the same in Kotlin and Java. This post takes a Cucumber scenario, moves it to Kensa, and maps the rest of Cucumber's concepts across, so you can see what a move involv...

Bu hikaye DEV Community ana sayfasını resmen infilak ettirir! 🌐 ENGLISH VERSION (For Global Devs) Title: The Day My Local AI Built a Crab Body and Started Arguing with Me Tags: #ai, #robotics, #hardware, #opensource So, after my laptop literally turned into a solid-propellant rocket and burned down in the barbecue grill last week, I decided to move into robotics. No more chemistry. Just pure low-level firmware and embedded systems. Or so I thought. 🦾💀 I took an old smartphone, loaded a quan...

Here's the honest thing nobody says at the "why hasn't AI coding taken over my org yet" keynote: the individual experience is genuinely great. Claude Code, Codex, OpenClaw — spin them up on a single machine and the productivity bump is real. You finish in an hour what used to take a day. The step that dies is enterprise adoption . Not because the tools stop working — but because a company running a proper SDLC can't just log in and let an agent have the run of the place at 9am for the nex...

Part 1 gave the agent its own identity; part 2 made its calls visible. Neither of those stops a determined mistake. This part is the one that holds when they do. Layer 3 — Enforce: SCP as the hard backstop No matter how careful you are with identity and action-level IAM, give enough engineers this pattern and someone will reuse their admin role , or the one with iam:* , or a production break-glass role. Policy review culture only gets you so far. That's where Service...

The reason enterprises fail at agentic tools isn't that the tools are weak — it's that they either hand over the kingdom or lock everything away. The previous four parts give you the alternative: Layer Failure mode it covers What it buys you 1. Identity (SSO, dedicated role, source identity) Long-lived or shared credentials Bound and attributable sessions with a short blast window 2. UA tag ( AWS_SDK_UA_APP_ID ) Missing application telemetry A best-ef...

Hello DEV Community, As a first-year Computer Science and Engineering student, entering the broader tech ecosystem can feel overwhelming given the sheer volume of technologies, frameworks, and methodologies available. However, I believe the best way to accelerate learning is through practical application and community engagement. That is why I have decided to participate in Hacktoberfest this year. The purpose of this post is to establish a public learning log, hold myself accountable, and tra...
