I'm trying to understand why I have so many ISR writes with Next.js and Vercel and have created a script which compares two builds, I'm now excluding updatedAt fields with Prisma, moved "use cache" outside of components which took in promises, tried to stabilize outputs from functions

Pro tip for evaluating LLM output is looking at its reasoning thoughts. Like humans if something is unclear/contradictory etc then LLMs will also struggle to make sense of it. Clarify your facts/statements in the prompt and you'll get better answers

Probably not a good idea syncing programming projects to a cloud backup solution causing a messed up git tree and me losing hours of work. Well, also changing branch with —force in panic.
Will be fine backing up old things not version controlled in GitHub, but GitHub stuff shouldn’t be synced..

In case you didn’t know when you reach the Fluid compute limits on a hobby plan on Vercel your website is paused and you must upgrade to Pro to enable it again. Guess how I learned this

When you’ve successfully isolated tests requiring a database by creating (and tearing down) a new database per test file, enabling you to fully parallelise them. Only for the performance in CI to now be worse than running the tests sequentially 🙈

Fixed a bug which involved making database changes and data migrations with the help of AI in @fantasy-snooker.com this morning.
Really enjoying using AI at the moment. Instead of coding sometimes feeling like a chore I’m now looking forward to it

I wonder if we MCP all the things and give AI/LLMs our task lists is it possible to 0-inbox it (unlikely, but we can dream)

I proposed a new eslint rule which would warn when you used type conversions like Number(foo) github.com/eslint/eslin.... The reasoning is that using these conversion methods opts out from type-checking. Any value can be passed to Number(foo).
Agree or naw? (the rule got rejected to core)

Forever trapped in this. Can you even build your site with use cache? Honestly it seems like an error in `next build`, but if it's not then this error should be shown during dev because the `next build` -> try fix -> repeat workflow is atrocious #usecache @nextjs.org

Why is it so hard to find a backup service which is cheap, has good performance and lots of features, deduplication, encryption and a data center in Europe?
Please helpz

It seems JSX is under the "react" module instead of global in React 19.
Which means if you do something like this to support custom elements (e.g. from a third-party lib) you must override the module "react" instead of global.
Also don't forget to import JSX from "react" where you referer to JSX.
