We Built Guardrails Against JSON Precision Loss. Then We Found Out Half of Them Weren't Actually Guarding Anything.

A few weeks ago I ran this through our own JSON repair tool, in the browser, on our own website: json {"id": 22233344455566677788} It came back as: json {"id": 22233344455566676000} No error. No warning. Just a quietly wrong number, presented as a successful repair. That number is a made-up snowflake ID, the kind of thing you'd see as a primary key in a distributed system. And our own tool — the one whose entire pitch is "we don't ship plausible-looking but wrong results" — had just silently c

How Java's Concurrency APIs Fit Together

A concurrency problem can begin with an ordinary requirement: let two independent Thread, ExecutorService, Future, CompletableFuture, locks, atomics, queues, and synchronizers is harder when they These APIs answer different questions. Some describe work, some decide how it We will build that map around a small customer-dashboard example, then use shorter Suppose an endpoint builds a customer dashboard from a profile and a list of recent var profile = loadProfile(); var orders = loadOrders(); re

I Brought IdentityServer Back to Life as Open Source (.NET 8)

I Brought IdentityServer Back to Life as Open Source (.NET 8) The original IdentityServer project was commercialized. Instead of letting it die, I took the codebase, recompiled it for modern .NET, fixed what was broken, and released it as open source under the Apache 2.0 license. This is not a wrapper — it's a working identity server that I rebuilt and verified end-to-end, with two sample applications proving that multi-app SSO and per-app permissions actually work. OAuth 2.0 + OpenID Connect

Two YubiKeys, One Prompt Too Many

I carry two YubiKeys. One lives on my keyring, one lives in a drawer, and both are enrolled everywhere that matters. A hardware token with no backup is a single point of failure you have chosen on purpose. For months I had a small irritation I never bothered to chase. Some days git push asked for my PIN, I typed it, and it worked. Other days it asked for my PIN, failed, and then asked again, and the second one worked. Same command, same repo, same laptop. The variable turned out to be which of t

Your agent asked for approval. Where did the answer go?

An agent drafts a refund decision. A reviewer reads it, changes the amount, adds a line about the customer's contract, and approves. The refund goes out. Everyone moves on. Six months later somebody asks who approved that refund, and why the amount changed. The agent's draft is in a trace. The final amount is in the payments system. The reviewer's reasoning was a sentence in a chat thread that has since scrolled away, and the fact that a human changed the number at all is not recorded anywhere a

Why "Vibe Coding" Fails Without a Behavioral Floor: A Browser-Verified Rerun

The Experiment We just published a comprehensive, browser-verified rerun experiment comparing uncontrolled AI-generated React/Tailwind against the newly released Toolcrib v0.5.0. If you are currently building frontends using autonomous AI assistants or "vibe coding" inside an LLM chat, this structural teardown shows exactly why relying on raw AI generation without a pre-tested component floor guarantees UI, UX, and accessibility drift. 👉 Read the full live-browser teardown here: Refactor App
