Just repeated this test. - Cursor with GPT 5 and Claude Sonnet 4 - Opencode with GPT 5 and Claude Sonnet 4 - Gemini CLI with Gemini Pro 2.5 - Claude Code with Claude Sonnet 4 You probably already know, but Claude Code is the real deal. Don't waste your time with anything else.

Just took another serious attempt on LLMs for solving a non-trivial / not-part-of-the-training-data software engineering task. Tried Copilot Workspaces, GPT-4o with Plandex-ai and Claude Sonnet 3.5 using the web interface and for all three of them the results were pure garbage. It costed my one hour. Which I think is a good price to get rid of the FOMO all this social media hype keeps building up.

How’s the fact that a query builder is more performant than an ORM even debatable?
oh so that's why the Prisma CTO is always beefing with the Drizzle dude

Merchants of complexity have convinced a shocking number of developers that they're too dumb to do their own authentication. Of all the things you could outsource, I think you could do no worse than your app's front door.
Clerk has been down with 500 errors for 20 minutes, meaning nobody is able to login or signup Really makes you think again if you want to outsource auth 😁

It might turn out that the GPT wrapper has more of a moat than GPT.

So many features @Apple. Well done. What about an iOS keyboard on which I can type in more than two languages? Maybe in 2030? It's incredible that I still can't type English, Spanish and Portuguese in an iOS keyboard without going through the hassle of changing keyboard language.

Oh @dhh, you make me chuckle. The vast majority of "TS devs" don't live anywhere near here, so maybe loosen the grip on your anti-TS baseball bat? 😆 Your quoted tweet screams library author/code. If anything, this is a simple testament that writing libraries and abstractions is definitely a 1% path. Even a vast majority of "just JS" devs can't be trusted to write decent library-level abstractions, let alone type-safe ones. Nothing is ever this binary, you know that. Just for kicks, let's write some "just JS"! Look ma! No TS! ... Well, spoiler alert, this is 100% type-safe code, backed by the kind of code you just slighted (and not even that much of it). Because of the 1% that invest the time into understanding static typing, generics, type-safe architecture that make writing TS virtually the same as never writing it. x.com/dhh/status/17885798739…

Never seen a better ad for ditching TypeScript. You don't have to live like this!!

TIL (the hard way) Apple's SIMD defaults to column-major order NumPy defaults to row-major order So if your matrix-vector multiplications aren't behaving, pick a side and blame the other.

Incredible, if you go to claude.ai and ask it to write some code and then to verify it by running, it won't run it but tell you it did it and it works flawlessly 🤣

We are lifting all restrictions. This judge has applied massive fines, threatened to arrest our employees and cut off access to 𝕏 in Brazil. As a result, we will probably lose all revenue in Brazil and have to shut down our office there. But principles matter more than profit.

I've always believed in the idea, but now after working with @expo again in a serious project, I can say that the product is really there. Engineering is about optimizing tradeoffs and @expo streamlines React Native development in the abstraction level that works best for your project, while still providing escape hatches for occasional lower level / native API access, bringing your downside to a minimum. I've been working with several features and most of them look pretty stable and mature. The docs are really well written and up-to-date. Looking forward to trying EAS in the coming weeks.

Sure. I think you guys are doing something great but expo has failed me once and the issue was exactly that: overpromising. I really hope the project is now more mature (it really seems to be) and I'm less likely to run into bugs, constraints and dead ends whenever I need to burst out of the expo modules bubble. Will definitely give it a go and report back.

The only fact worth worrying about regarding AI progress is the fact that @elonmusk worries about it.

AI will probably be smarter than any single human next year. By 2029, AI is probably smarter than all humans combined.

In essence, saying that a React Native app is inherently always worse than a native app __STRICTLY IMPLIES__ that: - A React SPA is inherently always worse than a JS only SPA. - An #r3f app is inherently always worse than a #threejs app. Most of the criticism on React Native arises from not understanding how it works.

Broadly speaking a Cloud Landing Zone is just a concept. It encapsulates the idea of having a baseline infrastructure setup, comprised of multiple accounts, that enables security, scalability, governance and compliance (as opposed to trying to do all that with a single account and / or not caring about those things at all).
