Notes on coding, tools, and side projects.
Massive parallelism
On a normal working day I have 50 or more agent sessions open on my laptop, and in any given half hour I’m switching between a half-dozen of them. The rest are waiting: on a reviewer, a pipeline, a merge, or an infrastructure change. Over the last week, the local software I run to feed those agents took about 300 actions without me, including 50 times it woke an inactive session to deal with something new and 30 times it completed the final stages of code review and merged. ...
RAGtime
My wife had a task to improve a few dozen blog posts with cross-links to relevant podcasts. She specs the task into her LLM chat agent. The agent interprets the requirements, and for each blog article searches the business’s 400 episode podcast catalog for the single best match, drafts a paragraph on why that episode is the right next listen, generates the HTML for an embedded podcast player, and ships the section into the blog posts directly on the live WordPress site. Forty blog posts are updated in a few hours. She of course created the base content, idea and task. I created a RAG AI agent system that executes it. ...
The Purge (home networking edition)
A few weeks after putting my new home network gateway in place, I logged into the AdGuard Home admin panel to look at what was actually happening on the wire. The query log was supposed to be a curiosity, not a project. One client immediately stood out. It was making DNS lookups for log-config.samsungacr.com, then config.samsungads.com, then events.samsungads.com, then amauthprd.samsungcloudsolution.com, then back around again, faster than once a minute. In the course of a few hours it had racked up several hundred outbound lookups and was climbing toward the low thousands. It was the chattiest device on the network by a wide margin: more than any laptop I was actually using, more than my phone, more than the always-on home server. ...
