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

14+ 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

14+ 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

43+ 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

12+ 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

13+ 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

13+ 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…...

ESLint took 4.4s to lint Vue's core. oxlint took 0.24s. Then I turned on the type-aware rules.

37+ min ago   (515+ words) ESLint took 4.4 seconds to lint 445 TypeScript files. oxlint took 0.24. Turn on the type-aware rules that most projects actually want and ESLint climbs to 12 seconds, while oxlint, doing the type-aware pass too, finishes in under one. I went in expecting to…...

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

36+ 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…...
