A code-first record of automation pipelines, small web apps, paper trading experiments, and AI-assisted development. Screenshots, commands, and failure notes are the main material.
Defaulting actor isolation to the main actor synthesizes an isolated deinit only for classes that do not write one. The classes that wrote nothing are the dangerous ones — the exact opposite of intuition.
I read five store product page A/B tests on the same day. All five treatments were the identical lever — synthesized captions — and the results spread from -42% to +325%. And my power calculation from days earlier was 9x wrong because it used pre-dedupe impressions.
MediaWiki API booleans are true if the parameter is present, whatever its value. exintro=0 cut article bodies to 292 characters, and verdicts built on those 292 characters permanently blacklisted 43 perfectly good topics.
I added an LLM review stage to an unattended publishing pipeline and committed it as verified. The verification: five Japanese posts, all approved. Here is what an all-approve result proves about a gate, and what it does not.
One commit added a channel-setup script and hook translation data. The channel side takes country and language as arguments and scales for free. The content side needs a hand-filled entry per app per language before the renderer has anything to overlay. A note on how deep 'multi-language support' actually goes.
My YouTube uploader already localized hashtags for web-app videos. The native-app branch still attached a single Korean base-tag set to every language. This post covers a fix that had landed in only one of two branches, the 20-line change that closed the gap, and what I still don't know.
I added a daily job that turns blog posts into video scripts and queues them before publishing. On purpose, its only source is the 27 blog posts I actually wrote, so it stops on its own once they are used up. Where to stop the automation turned out to be the real decision.
I moved my web apps and my Instagram bot into their own folders. Moving folders doesn't feel like a code change, but three scripts had the path hardcoded. The fix was five lines. Finding those five lines was the actual work.
I auto-crossposted my short videos to Instagram Reels, and the cover came out as the solid-color intro screen. The offset parameters were ignored for Reels, so I switched to extracting the cover image myself, hosting it, and passing its URL.
Several posts had placeholders where concept diagrams belonged, and posts with no video still rendered a video section. One commit added 17 diagrams and hid the empty video sections. One post still couldn't be fixed the cheap way.
My Instagram crosspost pipeline put the same default hashtags on every app. Nothing errored, because the pipeline only checked that tags were attached, never that they fit the app. This post covers generating tags once per app, caching them, keeping the defaults only as a fallback, and what I still don't know.
Told to promote only store apps, I audited four channels and found just one still pushing web apps. Swapping its content pool wasn't enough. Language, price claims, and tone all came along with it, and a running experiment window had to be reopened.
I set out to mask two identifiers across my blog and internal docs. I assumed that meant editing sentences. One of them was in a post's filename, which is its URL slug, so renaming it also meant changing the URL, the OG images, and a slug list in a design doc.
I was auto-generating shorts to promote web apps that give you a result. The question was in the video, but the answer sat behind a link. I switched to capturing the result page URLs directly so the answer appears inside the video, and uploaded the first one.
The launchd job that refreshes the store-listing file, the only grounding source for my auto-published Threads and Facebook posts, had zero runs since it was loaded. The cause was one plist key: Day=1. No errors, not even a log file, so nobody noticed.
