## Writing

- [Nine ways to work on files that live on another machine, ranked by small-file cost](https://purvansh.site/blog/files-on-another-machine): Measured on a 68 ms link: an sshfs read of one 13 KB file costs 372 ms, and 200 of them cost 74 seconds. Nine options, ordered by what they do about that. (compute, checked 2026-09-07)
- [Six secret scanners against sixteen planted credentials, and what each one walked past](https://purvansh.site/blog/what-six-secret-scanners-miss): I hid sixteen fake credentials in a git repo across seven kinds of hiding place, ran six open-source scanners, and counted. All six missed the same one. (devtools, checked 2026-09-06)
- [Uber's agent stack taken apart, and the part its write-up leaves out](https://purvansh.site/blog/ubers-agent-stack-and-the-part-left-out): Uber published the gateway, the token service and the MCP layer. It never published what happens when a model dies mid-request, which is the part that broke my own cascade three times. (ai-architecture, checked 2026-09-05)
- [Seven self-hosted AI agents, with the numbers pulled from the API not the blog posts](https://purvansh.site/blog/self-hosted-agents-checked-at-the-source): Every comparison article I found was stale by more than a hundred thousand stars. Here are the seven, ranked on what the repository itself says about them today. (devtools, checked 2026-09-05)
- [Six vector stores, compared on how many vectors the free tier really holds](https://purvansh.site/blog/vector-free-tiers-measured-in-vectors): Every one of these advertises its free tier in gigabytes. Nobody embeds gigabytes. Converted into vectors at a common dimension, the gap between the most and least generous is about forty times. (ai-architecture, checked 2026-09-05)
- [Five hosts for a small site, compared on the limit that stops you first](https://purvansh.site/blog/where-the-free-hosting-tier-actually-stops): None of these run out of bandwidth. They stop on a build quota, a plan migration you cannot undo, a Git permission, or a clause saying your site is the wrong kind of site. (compute, checked 2026-09-05)
- [Six ways a deploy goes green while the old code keeps serving](https://purvansh.site/blog/green-deploys-that-are-not-live): Every one of these reports success somewhere and failure nowhere. The pattern is the same: the signal you are watching is upstream of the thing you actually care about. (practices, checked 2026-09-05)
- [Six ways to reach Postgres from a serverless function, ranked by what breaks first](https://purvansh.site/blog/reaching-postgres-from-a-serverless-function): The connection string the dashboard hands you is the one most likely to fail from a serverless host. Here is what each route actually does, and the error you get when it is the wrong one. (ai-architecture, checked 2026-09-05)
- [Eight uptime monitors compared on catching a 200 that is lying](https://purvansh.site/blog/uptime-monitors-that-catch-a-lying-200): A serverless function that was never deployed answered 200 with the app shell. Here is what each free tier lets you assert on the response body, and what the first paid dollar actually buys. (devtools, checked 2026-09-05)
