I'm trying to append an element to an array. But i cannot ensure that the array alread exists. So it should be created if not. This example works: Source json: { "data": [] } Patch doc: [{ ...

I am fed up with all the kubernetes DSL. helm and kustomize may do the work, but I need to learn a lot to do my job. E.g. a task as simple as copy and modify existing StorageClass to support Retain ReclaimPolicy is not easily achievable to me. I need to learn a ton of the syntax and semantics.

Remember 1 hour of vibe-coding can save you 1 day of debugging.

This is what I get for upload the wrong format of file for a batch generation task. I gave up.

Gemini's batch generation api is a PITA. Some configs for normal generation (e.g. think config) are not available in batch generation. What's worse, you can pass a pillow Image.Image to generate_content, but you have to "reverse engineer" gemini source code to figure out to to serialize an Image.

Scratching head for cloudflare r2 CORS responses. Turned out there are two requests, one with Sec-Fetch-Mode: no-cors and the other with Sec-Fetch-Mode: cors. The result of the first request was cached. Today's hero community.cloudflare.com/t/problem-wi...

The magic of next.js. You are building your nextjs container image, and it will actually try to connect to your database.

Gee. Open telemetry and grafana cloud is really a godsend. Super easy to setup, yet extremely powerful (hope to show some dashboard porn soon, but for now, not enough data). Plus, grafana cloud is just too cheap.

My day so far.

I have to confess my love for nextjs. This affection does not stem from its ease to use or unparalleled power. Having went through countless seemingly un-decipherable errors of nextjs should be a competitive edge for me. I hope nextjs would be more widely adopted. All my efforts shouldn't be in vain

It is 2025, and you can't see what went wrong with your CORS requests. None of the solutions in stackoverflow.com/questions/57... worked for me. Just show me the raw CORS request and response instead of a vague CORS error. God damn it.

I tried a ton of html to image libraries. None of they solve the problem "Error: CSSStyleSheet.cssRules getter: Not allowed to access cross-origin stylesheet". Most of the issues remain free-standing for quite a few years. github.com/bubkoo/html-... Alas, firefox is really not loved.

As a detective who has a lot of time bisecting, I love to solve nextjs mysteries like this. The less clues, the better.

Nextjs is really a PITA.

I am horrified by typescript programmers' abuse of type inference on almost dynamic objects and functions. Can we just disband dynamic evils once and for all? Why would anyone prefer zod over real static types? Please use derive/deriving as in rust/haskell while crossing the boundary.

Functional programmers, guess why you have this error. One does not simply use pattern match with typescript. All you have to do is forget the good old days.

stackoverflow.com/questions/71... "Can we all agree this error message is worse than useless?!" My vibe-fu is strong enough to have the error "Hydration failed because the initial UI does not match what was rendered on the server", weak enough to not be able to ask the agent to try ~50 solutions.

I almost gave up on using better-auth APIs from my nextjs server side. Turned out there are `createAuthClient` in both `better-auth/client` and `better-auth/react`. Confusing enough, I need to use `better-auth/client` in my nextjs server. www.better-auth.com/docs/referen... .

Am I doing it wrong? Or, it's just prompting requires more work? The result generated from this prompt is really underwhelming. For this particular example, I should have used better-auth's client API instead of creating back-end interfaces. Neither me or the "agent" was smart enough.

Some of the things are not open source (like vercel/og), which by itself is understandable. But given all the broken things I encountered in just a few days, I strongly believe that vercel is on its way to enshitification. These things may be broken by design.

There is also a feature disparity between vercel.json config and project config on the web. There are something you can set with the web interface (e.g. root directory), but you can't do that with vercel.json. Building on monorepo has been broken for years github.com/vercel/verce....
