Why We Built Bitweave: Sub-Millisecond Hybrid Retrieval in <1.1 MB RSS Memory

When building local RAG (Retrieval-Augmented Generation) applications, edge agents, or serverless AI pipelines, developers usually hit a wall with standard vector stores: memory overhead. Running a dedicated vector database locally often demands hundreds of megabytes—or gigabytes—of RAM just to keep indices warm. On the flip side, lightweight local options like scanning raw JSON files or querying...

Port Support You Can Trace Back to a Green Test

“Supported on iOS, Android, desktop, and web” sounds useful until you need one method on one target. Does WebSocket work on watchOS? Which Linux architectures do we build? Was the JavaScript media test green this week, or did somebody update a table six months ago and forget it? What is Codename One? Codename One is an open-source framework for building native iOS, Android, desktop, and web app...

How I Built an NDA-Safe CSV to Markdown Converter (100% Client-Side)

If you write documentation on GitHub, GitLab, or use Obsidian, you deal with Markdown tables. And you know they are a pain to write by hand. The Hack Aligning pipes (|), escaping special characters, and maintaining readability in plain text is tedious. The usual shortcut is to copy data from Excel or a CSV file, paste it into a free online converter, and grab the markdown output. But ...

garden-skills packages taste and process for AI coding agents

ConardLi's garden-skills makes a specific bet: what holds AI coding agents back is not raw capability but taste and process discipline. Each skill in the collection ships as a full production surface with opinionated defaults and hard stop points, not a loose prompt you paste and hope works. garden-skills is a curated set of production-ready Agent Skills for Claude Code, Cursor, Codex, and other ...

Before Grok Build Uploads Your Repo, Show the Outbound Receipt

Coding agents create an awkward security moment. A developer can understand the task they typed and still have no compact answer to a more important question: what is about to leave this machine? The answer may include more than a prompt. It can involve file contents, paths, repository metadata, environment details, identifiers, or a separate upload flow. Network inspection can reveal those detai...

Anonymous AI vs Private AI: Not the Same Thing

Someone on our Telegram asked me last week whether a certain AI provider was "private." I gave a two sentence answer, then spent the next ten minutes untangling it, because the question was hiding two completely different questions inside it. Here is the short version. Private AI means the provider cannot read the content of your prompt. Anonymous AI means the provider cannot tell the prompt came...

"I Haven't Written Code in 8 Months. I've Never Built More."

I've been having the same conversation with my colleagues for months. What does it mean to create educational content for developers when the audience is shifting to people who may not write code at all? In Episode 7 of Making Software, I talked to James Quick, Developer Educator at Cloudflare. He's been in developer relations for 13 years, starting at Microsoft before most people knew that was ...

LLD Data Structures in Design Context: Why Software Engineers Think Differently About Data Structures

"Learning data structures teaches you how to write efficient programs. Learning Low-Level Design teaches you why those same data structures quietly become the backbone of real software systems." If you've prepared for coding interviews, you've probably spent weeks—or even months—learning data structures. Arrays. Linked Lists. Stacks. Queues. HashMaps. Heaps. Trees. Graphs. Tries. You ...

Pilot Then Fan Out: Killing Unknown Blockers in 2 Repos First

I maintain about a dozen small products that share one homemade framework. Last week I built a conformance linter — a little tool that scans each repo for architectural drift — and I was one command away from wiring it into all of them at once. I didn't. I ran it in two repos first. That two-repo dry run is the cheapest safety I've added all year, and it caught two things that would otherwise ha...

This is the follow-up: the same idea, applied to the whole machine instead of one project. My entire user environment lives in a single Git repo. Packages, shell config, aliases, git, tmux, the editor. Everything I care about, basically. When I get a new Mac, I cl...
