Why Independent Developer Blogs Are Going Offline
Independent developer educators are losing readers and income to AI. What you can do about it, and how I block training crawlers on this blog.
Sculpting DTS support into a 2020 LG CX
My LG CX shipped without DTS support. Bringing it back meant reconstructing its audio DSP firmware and restoring the missing DTS handling across eight layers of the TV’s audio stack.
ADD CONSTRAINT UNIQUE runs in milliseconds and locks nothing that matters, then aborts on a duplicate email. Fixtures hide it and so does uniform random data. Here is the data shape that exposes it.
A speed-dating puzzle about moving sixteen people between four tables leads to finite fields, affine planes, and a surprisingly rich scheduling problem.
What REPACK (CONCURRENTLY) costs while it runs
PostgreSQL 19 comes with online table rewrites. Measured against pg_repack and pg_squeeze REPACK (CONCURRENTLY) is the fastest and the lightest on WAL under writes. Here's what it does to vacuum, readers, writers and old snapshots while it runs, and what to ch…

Build the Harness Before You Hand the Agent Real Work — Matthew Boston
AI agents guess, and they guess fast. Linters, type checkers, the compiler, formatters, and a real test bed are what turn those guesses into verified changes. The tighter that loop, the more of the build an agent can safely own.

I reran my Denial of Spend test on GPT-6 Astra, Sol and Luna and Claude Fable 5.1, Opus 5.5, Sonnet 5 and Haiku 4.5. None were fooled by lookalike letters, and all of them still paid to read them: up to 5.7x the tokens and up to 3.9x the bill.

I write less code by hand, ship more software, and spend much more time deciding what I am willing to own.

I have been following the AI debate from the sidelines for quite some time now. I wanted to stay out of it for several reasons: I am not an expert, in fact (except for the most basic applications) I am not an actual user, and there are way too many other…
RAG Over Markdown: An End-to-End Local Pipeline in Pure PHP
RAG without the vendor mystique: chunk, embed, index, retrieve, generate — a complete question-answering pipeline over markdown docs, every stage running locally in PHP.
DHH’s ‘pencils down’ moment at Rails World points to a deeper shift: AI is becoming the abstraction closest to human intent. What does that mean for Ruby, Rails, JRuby, Spinel, Elixir, and the future of programming?
Speeding Up the Process of Mourning

There are many reasons to write by hand, instead of using AI. A classic reason is that writing is thinking — in other words that if you’re not writing, you’re not clearly thinking.
Structural duplicate detection cannot tell a pasted copy from a shared idiom. cargo-crap 0.6.0 asks a TypeSafe model which pairs to merge and which to leave alone.
