Software Development & Infrastructure Insights
A Karpathy-style Obsidian vault is a great memory for one developer and one AI session. It starts to break down when a whole team of humans and agents depends on it. A local pgvector index in front of the vault is the fix: here is the token math, the shared-memory payoff, and the honest costs.

Most companies experimenting with AI do not have a model problem. They have a knowledge problem. Here is how we are building a governed knowledge layer that connects company information to Codex, Claude, ChatGPT, and future AI tools without surrendering control of the data.

Almost every pgvector tutorial teaches semantic search over text and stops there. But pgvector is a nearest-neighbor engine, not an embeddings feature: for structured data where you already know what makes two things alike, a hand-built feature vector you can normalize, weight, and explain beats a black-box embedding. Here is the distinction, with a worked example from a real "find similar players" build.

We ported one of our own production .NET applications to Rust to find out where the language actually earns its cost. The honest answer surprised us: a rewrite is almost never about which language is better. Here is the scorecard, the hidden costs nobody quotes, and the four questions that decide it.

The web is filling with AI-generated slop, and the models your buyers use are being tuned to ignore it. Here is why getting cited by AI now matters more than ranking on Google, and what executives should do about it.

inotify doesn't work on network-attached storage. Polling a 500,000-file archive takes two minutes per cycle. ZFS's copy-on-write block pointer tree was a filesystem CDC system all along — making change detection O(changes) instead of O(total files).

We replaced a 765-line multi-engine OCR pipeline with a single 0.9-billion-parameter vision model running on a Mac. The new system is simpler, more accurate, and every byte of data stays on premises.

Generative AI will transform how production companies use their archived footage. But AI cannot work with unstructured video files. The companies that index their archives now will have a massive head start.

A client was spending thousands per month running every AI coding task through premium models like GPT-4o and Claude Opus. We restructured their workflow to use the right model for the right job and cut their bill by 80%.

LTO tape stores data at about half a cent per gigabyte, and an unmounted cartridge is ransomware-proof by design. A petabyte-scale operator walks through how to size it, plan retrieval, and avoid the expensive mistakes before you buy.

AI tools can build a website in minutes. That speed comes with real risks: security holes nobody audits, over-engineered code nobody understands, and a web that is starting to all look the same.
