Conceptual Contours

Domain Excavation Because it requires constant discovery and refinement, building software is much like excavating a buried house. One requirement exposes a section of wall. A bug fix reveals a doorway we hadn’t accounted for. A conversation with a user turns up a hearth or a pottery shard. Gradually, the pieces begin to suggest architectural features yet to be discovered: rooms, connections, and the activities they supported. Recognizing the architectural whole changes how we understand the p

NFL playoff odds after Week 1 (2026): why my Monte Carlo model barely trusts a 31-10 win

Week 1 of the 2026 NFL season is done. Sixteen teams are 1-0, sixteen are 0-1, and every sports show is already telling you who is "for real." I build a Monte Carlo simulator that estimates NFL playoff odds for all 32 teams, so I wanted to know how much one week should move those numbers. The model's answer is "not much," and the reasons are more interesting than the numbers themselves. A common way to estimate team strength is the Pythagorean expectation. You take points scored and points allow

Why we built recall-first search on PostgreSQL

Our careers page search often felt broken. Searching for “Java” could return JavaScript roles. A misspelling could produce no results at all. Searching for “manager” could collect assistant-manager vacancies across unrelated departments, without distinguishing what those jobs involved. The implementation was matching words inside job metadata. It did not understand spelling variations, equivalent terminology, or descriptions of the work a candidate wanted to do. Relevant vacancies could disappea

Menavigasi Tantangan Concurrency di Go: Mengatasi Data Race dan Optimasi Performa di Tahun 2026

Menavigasi Tantangan Concurrency di Go: Mengatasi Data Race dan Optimasi Performa di Tahun 2026 Berbicara tentang Golang hampir certainly akan membawa kita pada pembahasan mengenai concurrency. Sejak awal kemunculannya, goroutines dan channels telah menjadi daya tarik utama yang membuat Go menjadi pilihan favorit untuk membangun sistem backend yang scalable. Namun, seiring dengan berkembangnya kompleksitas aplikasi yang kita bangun di tahun 2026, kita mulai menyadari bahwa kemudahan menulis ko

Downloads Without Boilerplate: Saving HTTP Responses to Local Disk with `--output`

Downloading a file in OkHttp means streaming ResponseBody, choosing a sink, and closing resources correctly. In JQuickCurl, a download is just another curl command: add --output './download/report.pdf' (or -o) and the executor writes the response bytes to that path for you. No InputStream juggling, no try-with-resources plumbing in your business code. This post covers: The --output one-liner that saves straight to disk. Returning byte[] and saving in Java for full control. Combined approache

Approval Is Not Publication

The step everyone builds, and the step that actually moves work The standard architecture for putting AI into a business is easy to draw. Data We built exactly that. Then I looked at the queue and found 37 pieces of work One approved, and nothing published. The diagram has four boxes and everyone builds the first three. Data collection The last arrow, from approval to action, is plumbing. It is also the only part We changed the meaning of the button. Approval is now a publish instruction, not
