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...
