## Technical writings

- [Adaptive locks and lock-free trees. I would unique the OnMission claim, not port Arctic](https://adhikariayush.com.np/blog/adaptive-lock-lock-free-onmission-unique-not-mutex): OSDI’s Arctic paper is the concurrency story this week. I would unique the OnMission assignment claim and retry a P2002. I would not add a Redis lock to a Stripe webhook. Here is the five-step check.
- [Zod 4.5 shipped. I would compile Ask Ayush, not every DTO in Lahebo](https://adhikariayush.com.np/blog/zod-4-5-compile-ask-ayush-not-every-dto): Friday’s Zod 4.5 post is the validation story this week. I would compile the four schemas this site already parses, then stop. Here is the five-step check before I bump a lockfile.
- [OpenAI cuts Cursor on 12 Nov. I would not pin Lahebo to an editor model](https://adhikariayush.com.np/blog/openai-ends-cursor-models-pin-npm-tonight): Friday’s OpenAI notice is the software story this weekend. npm shipped a Shai-Hulud variant the same night. Here is the five-step check I would run before I change an editor or a lockfile.
- [NestJS 12 shipped. I would dry-run Lahebo this weekend, not rewrite every DTO](https://adhikariayush.com.np/blog/nestjs-12-dry-run-lahebo-this-weekend): Thursday’s NestJS 12 release is the one that actually touches Lahebo. Yesterday’s agent headlines are interesting. Here is the five-step check I would run before I bump a single package.
- [AWS bought DuckLabs. Try DuckDB on a report, not on the SyBazar order table](https://adhikariayush.com.np/blog/aws-ducklabs-keep-duckdb-off-the-write-path): Amazon signed for the company behind DuckDB on August 26. The project stays MIT. Here is the five-step check I would run before I let an analytics engine anywhere near a write path.
- [A browser redirect is not a payment. Webhooks retry, so your table has to refuse the second delivery](https://adhikariayush.com.np/blog/stripe-webhook-is-not-a-redirect): Stripe, GitHub, Shopify, and every wallet you have ever integrated will POST the same event twice. Here is a five-step inbox that works on NestJS and Prisma — and still works if your provider is not Stripe.
- [Agent Plugins 1.0 is on daily.dev. Ask Ayush still swallows one FACTS dump](https://adhikariayush.com.np/blog/agent-plugins-ask-ayush-facts-dump): Amazon, Cursor, Google, Microsoft, OpenAI, and Vercel agreed on a plugin folder. I still paste the whole site into Gemini on every question. Here is the first file I would extract — and the one plugin I would not install.
- [I read the Stripe–OpenRouter news and then opened my own chat code](https://adhikariayush.com.np/blog/stripe-openrouter-model-routing): Stripe wants OpenRouter. Everyone is talking about model routers this week. I still send name checks and real questions through the same Gemini door. That has to change.
- [Patch OnMission’s Postgres this week. Prisma will not do it for you](https://adhikariayush.com.np/blog/postgres-18-6-patch-onmission): PostgreSQL 18.6 landed on August 13 with 28 security fixes. Here is the five-step check I would run on OnMission and LOMA tonight — binaries, not a schema migration.
- [Try Cursor Origin on a side project without moving production](https://adhikariayush.com.np/blog/cursor-origin-agent-native-hosting): Cursor shipped Origin on August 17. I would try it on HelloFutsall first, keep GitHub as the remote, and copy the merge gates I already use on SyBazar.
- [GitHub’s 8-hour outage was a retry bug. Check yours tonight](https://adhikariayush.com.np/blog/github-outage-vscode-retry-storm): The Aug 17 GitHub incident is what every team is talking about this week. The RCA is not “GitHub is down again.” It is optimistic retries, a VS Code 10x storm, and an autoscaler watching the wrong process.
- [Ask Ayush: the on-site assistant on this portfolio](https://adhikariayush.com.np/blog/ask-ayush-on-site-assistant): A new section on this site. The corner chat answers from my real profile, projects, and notes — not as a general chatbot. Here is how to use it.
