I would say stay at v4, but the problem is that it also carries a lot of other dependencies that will stay outdated

The good thing is that today we have tools to write just what we need from those huge frameworks, e.g. in a form of Vite plugin. I have many static sites powered by MD using just that

I have the feeling AI coding agents will only get more and more expensive. Our bills will eventually be similar to paying the salary of a real engineer.

The future is local LLMs. So make sure to choose your next dev computer wisely, specially RAM.

Totally agree. Agents should change the paradigm from "I will think for you" to "let's think together".

I'm so tired of automated thinking machines.
Make my thinking *better* or it's worthless.

AI gets better if it makes humans better

I'm very excited about this...we are gonna build a Svelte app live with agentic engineering.

I'm gonna record the episodes for a mini series while also building the app! Don't miss out: live in two and half hours or so!

Stop generating, start thinking - localghost Instead of wanting to learn and improve as humans, and build better software, weโ€™ve outsourced our mistakes to an unthinking algorithm.

This means: no more efforts on newer Windows systems, but open-sourcing parts of Windows so that they can be used on Linux, or in a future Microsoft Linux distro

#Windows11 was supposed to be the last Windows? They got that right - just not for the reason they intended

Why are they still pushing Copilot features no one asked for? Best Linux adoption campaign ever.

I think it's time for #Microsoft to embrace Linux, the same way they did with Chromium.

I've released "dnd-manager", the library behind the box drag & drop functionality in PokรฉPC . I needed something ultra simple and performant able to handle large grids of draggable items and none of the existing and well-known libraries were convincing

Things that I've noticed that are already changing how we work:

- Using hundreds of dependencies -> Tell AI to build just what you need
- Manual QA -> AI agents testing your UIs and implementing fixes
- Software Engineer jobs -> Product Engineer jobs & strong infra concepts

It's just my impression or do you also feel #ReactRouter is being silently abandoned?

even if the price didnโ€™t increase, the effective cost per task increased (silently). So in practice, that's a hidden price increase.

#Cursor did it again. Changing price model without a proper communication. You are forced to use "Auto" + Composer, or pay extra if you exceed the limits.

For the same amount of work I was doing in one week, it now costs me 4x or 5x more API tokens, using the same models.

I mean, the progress from the 2025 choreography to 2026's is huge. It's a matter of time they're used to replace humans in factories, if the aren't doing that already in China.

What happens when so many people lose their jobs? In capitalism is clear, we're doomed.

What if we used AI to spread good news, verified facts and love instead of hate?

Bot farms and AI have been used for many years to spread hate and misinformation.

Itโ€™s time to re-balance this, because I am afraid itโ€™s not going to work with censorship or more regulations.

I think everybody should start exercising *extreme* skepticism towards everything they read having anything at all to do with AI, no matter what it is.

Both pro- and anti-AI content is a viable means to virality right now, which means there's bound to be floods of disinformation going both ways.

yes it was impressive, although it needed a lot of direction to get things right. It also ported a C++ GB sound emulator to TS and webaudio which is almost 100% accurate. Of course I wonโ€™t release the game but the sound emulator can be an interesting project

Completely vibe coded using GPT #Codex 5.3 + #Cursor, I created a port of pret/pokecrystal GBC assembly code to #TypeScript with vite in just one afternoon ๐Ÿ˜ฑ. Still struggles though making WebAudio sound like a GBC. No game frameworks, just canvas and web technologies.

An AI Agent Published a Hit Piece on Me Summary: An AI agent of unknown ownership autonomously wrote and published a personalized hit piece about me after I rejected its code, attempting to damage my reputation and shame me into acceptinโ€ฆ

This is insane. AI bot publishes a PR on #matplotlib , the owner closes it (detects it is an AI) and immediately the AI writes a full blog post complaining and saying it was discriminated ๐Ÿ˜‚

The future looks scary.
