Kairos 1.0 — a schedule language where "3 business days before month-end" is an expression

23+ min ago   (268+ words) Today I tagged 1.0 of Kairos, a schedule definition language I've been building — a small DSL where schedules like "3 business days before month-end" or "payday on the 25th, previous business day if it's a holiday" are single expressions. cron can say "the…...

Migrating from crontab: five everyday schedules, translated into Kairos

22+ min ago   (670+ words) If you arrived from the Kairos 1.0 announcement, this is the hands-on one: take a crontab you already have and translate it. First, the honest part: if your jobs are plain fixed-time repeats, stay on cron. "Every hour", "3am daily" — there is…...

Bot Detection False Positives: How to Actually Test Accuracy

51+ min ago   (1443+ words) The fastest way to lose confidence in bot protection is not to miss a bot. It is to block a real customer. A missed scraper costs bandwidth or content. A blocked customer costs a sale, a support escalation, and trust…...

How I Turned the SAM.gov Public Bulk Dataset Into a Searchable Contractor Database

21+ min ago   (718+ words) Working with public government datasets often sounds straightforward until you actually try to turn them into something useful. That was my experience with the SAM.gov public bulk dataset. The data is valuable because it contains a large amount of…...

My parser reported a parse error on a file that was never malformed

22+ min ago   (554+ words) A build step that reads requirement tables out of a document reported this, every run: reason=parse has an obvious reading. Either the document is malformed or the parser is broken. A person following that reason code goes and looks…...

A deprecated value has to live somewhere, and widening the set was the wrong somewhere

22+ min ago   (590+ words) A check refused a row I had just added. The row was a retired signing key, kept so that records signed under it can still be read. The check said: The set of accepted schemes has exactly one element, and…...

I Built a Python CLI Toolbox Instead of Writing One-Off Scripts

26+ min ago   (666+ words) Whenever I ask an AI assistant to do a small task, it writes a quick Python script for me. Convert an image. Compress a PDF. Convert a CSV to Excel. The script works, I use it once, and then it…...

AI Agent Authentication in 2026: Web Bot Auth, ARD & OAuth

51+ min ago   (1061+ words) AI agent authentication is not one protocol. It is a stack. An agent may need to discover a tool, prove which workload is running, authenticate an HTTP request, show that a user delegated authority, and leave enough evidence to reconstruct…...

How to change reasoning effort in Codex CLI: model_reasoning_effort values and one-off overrides

45+ min ago   (430+ words) Codex feels slow, or it overthinks a trivial fix. The knob for that is reasoning effort, the Codex counterpart of extended thinking in Claude Code, controlled by the model_reasoning_effort key. In short: set model_reasoning_effort = "high" (or another value) in ~/.codex/config.toml…...

Browser Fingerprinting in 2026: What Still Works, What Doesn't

51+ min ago   (1267+ words) Browser fingerprinting still works in 2026, but the useful techniques have shifted underneath everyone. Chrome's Privacy Sandbox has frozen or removed half the signals fingerprinting libraries depended on. Firefox and Safari added noise injection and API restrictions. Brave blocks attempts outright....
