Im the only one no longer uses terminals apps, not even IDE's, now not even terminals.

Claude/Codex app all the way baby. What a crazy world.

jvidalv··on Google cleared 300 hectares of Finnish forest
The first think I did when I saw the number is to google how much trees finland has.

Estimated 33 trillion trees. I think they will do fine with 250k less trees.

jvidalv··on Security Disclosure
As an european, just woke up to this, wow crazy.

All my apps are on Railway, deployments has been down since yesterday morning (24 hours), feels nuts that they have waited until 2AM to say this.

Keep going man, switch countries, never call it done.

You never know what awaits behind the corner.

jvidalv··on JetBrains reported a net financial loss first time in its tracked history
I have completely stopped using Jetbrains products since 6 months ago. Like all, not gonna even renew my subscription.

Heavy user of WebStorm and Datagrip since at least 2019.

jvidalv··on What happens if an entire class of workers loses faith in their careers
Small forums is the answer. In spain they are still popular and after some time it feels like an small town in the good sense, you know everyone and everyone knows you. Of course small forums will not IPO
jvidalv··on You don't need React: creating a minimal UI library in Vanilla JavaScript
I “agree” with your “sentiment”.

But I can’t shake the feeling that discussing this stuff is indeed void on the AI era. I considered my self a JS/TS/React expert dev, derivate, state duplication, url as a source of truth…

All of these points feel void now, I have not checked/cared how my React code looks like in months now. I only care about more high level stuff like schema definition and overall wiring.

Also interested.
jvidalv··on OpenAI’s accidental attack against Hugging Face is science fiction that happened
Are you serious? Before LLM’s you needed serious skills and experience to pull this off.

Now it’s a prompt away on some terminal done by any random dud.

And I dont mention the velocity of iteration or that they will be even better in 1 year.

jvidalv··on EU Parliament greenlights Chat Control 1.0
You will be surprised to discover that the most open pro-democracy and “leftist” are also the most fascist and speech controlling ones.

At least in Spain this is exactly the case, and is really scary how much people falls for it.

jvidalv··on Stop wasting tokens and re explaining your project between sessions
They don’t. It’s all based on FOMO. Like superpowers, the more the better.

My advice: the best claude is the raw claude, with some custom tailored skills. That’s it, no plugins.

jvidalv··on Bun has an open PR adding shared-memory threads to JavaScriptCore
Bun is so good that can’t be used as server and only as local script runner.

Leaks memory left and right. And the core team seems unable to fix it.

jvidalv··on Tailwind and slop apps
This is completely wrong, all this pages are mine and are Tailwind:

https://berrus.app/ (game) https://josepvidal.dev/ (my site) https://fescims.com/ (mountaineering community)

Even my mobile app for the mountaineering community is tailwind (Yes, there is Tailwind for ReactNative): https://apps.apple.com/us/app/cims-mountain-challenges/id674...

My point being, quick AI slop landing pages and products will share the same vibes, but at the end Tailwind is just a collection of css classnames, allowing you to build and create as much as cool and unique pages as with plain css if you put the effort.

jvidalv··on AI is eating your moat
Fair reframe, and I agree more than I disagree.

It's actually why I stopped at Railway level instead of going full VPS.

jvidalv··on AI is eating your moat
Exactly, it always was one. The UX premium was a price on friction, and agents are pushing the price of friction to zero.
jvidalv··on AI is eating your moat
It's not about hard, it's about priorities.

I wouldn't switch from Vercel just to save X% per month, because the real cost was all the extra time to build and maintain the infrastructure myself. The savings never justified the hours.

With agents that math changes. The build and maintenance work moves onto the agent, so the savings threshold where switching makes sense drops a lot.

On top of that there are other goodies. Vercel is serverless, so you can't co-locate the API with the DB, which means extra latency and yet another bill (Supabase?). That's one more thing you can now own for basically no effort.

Bit of an stretch here.
jvidalv··on Search engines alternatives now that Google isn't Google anymore
I mean, the root problem is, who searches anymore? Or better said, the ones who search are decreasing exponentially.

I only use Google to search for reddit posts.

The rest is ChatGPT or Claude.

jvidalv··on The Eternal Sloptember
Thanks for the message, is exactly what I have in my brain and how I'm seeing it unfold.

I'm lucky to be part of different codebases, +200 engineers codebase in a 10 years old company and code, +5 engineers on fresh code. My personal projects, that are beyond POC's, real users, hundreds of commits.

The LLM agent sweet spot is the last one, they are perfect, as I can contain most of the knowledge in my brain of how it works in/out. Speed is insane as a solo developer.

Then the 5 engineers codebase, is also really good, but here you already start to see the problems, thanks to agents you don't even need to care how it works, I have been working on it for +6 months, it uses TRPC and I don't even know (I don't care) how TRPC works. You feel that no one in the team really knows how stuff works at 100% (fresh codebase, we have build this ourselves!!).

Then there is the old codebase with +200 engineers, this is the worst of all of them, you described it perfectly, a bottomless pit of tech debt. This codebase before agents was an old non-typescript one, it was not perfect, but you could build a mental model and understand it perfectly after a few weeks working on it. Now, is a hot-mess of code duplication and the quality is degrading faster and faster as the code gets worse and the Claude Code adoption increases within the engineering team.

Not sure what will be the outcome of all this, but I wouldn't be surprised if some company wakes up in 2027 with a codebase that maintenance and development has increased by x100 fold thanks to Agents.

jvidalv··on Was my $48K GPU server worth it?
I also call this "bollocks" there is no way this workflow is even 1/10 of what you can get with Codex/Claude Code.

A normal engineer may be running a couple of sessions with every session spawning sub agents left and right.

80 persons or even 10 having this workflow on this setup doesn't work, and this is the standard engineer workflow today.

Not caring.
jvidalv··on Solar-based sleep patterns compared to modern norms
My brain translates it from: "su propio" -> "it's own".

Don't ask me why, thanks for the correction

jvidalv··on Solar-based sleep patterns compared to modern norms
You nailed it, commute is the killer. I'm also Spanish, from a very small and rural town.

My father is a farmer and does a siesta every day of the year. He comes back at home of working in the farm every day around 1PM, then we have lunch together and he goes on to take a nap (siesta).

In winter they are shorter, 30 minutes, as the day is short.

In summer, they can go over 1 hour easily, as the day is longer and is hot between 2 and 5 PM.

Of course, my father is it's own boss and old school farmer, young farmers don't do that, and try to work on an schedule.

And is the same about school, when I was a kid no one was driving me to the school or taking me back, I walked there on my own, went home at mid day for lunch, played some football after it, and then went back to school for a couple of hours at 3PM.

I feel we are slowly drifting away from natural times and actions to forced on schedule behaviour to fit within the cogs of a late-stage capitalism productive machine.

Bun can't be used for anything serious, only as a "script kiddie" to run small scripts.

Trying to run it as a replacement for node in persistent backend/api scenarios is just plain broken.

jvidalv··on OpenAI releases GPT-5.5 and GPT-5.5 Pro in the API
In the only one that feels that OpenAI has bots/commenters on payroll on all this kind of news downplaying Claude and stating how much better Codex is?

There is too much and there are too many, and some of their takes don’t fly if you use Claude daily.

jvidalv··on TanStack Start Now Support React Server Components
Same principle applies, hosting in Railway has slightly worse UX, but with LLM's you don't need to write a single docker line anymore, so deploying on railway is way way less cumbersome than before, and you gain more control and less costs.
jvidalv··on TanStack Start Now Support React Server Components
This is something I noticed, originally I thought "AI" was the perfect tool for Vercel and Nextjs (current standard = future standard), but then I realized is the total opposite, their moat/stick is gone now, and Rouch that is smart I think knows this.

I switched a middle sized app to Tanstack Router + Vite while I was walking my dogs. Then 30 minuts-1 hour QA and it was done. This should have never happened before AI.

(I did switch because I was tired of the bloated network tab with 100 unnecesary RSC calls, the 5 seconds lag when clicking on an internal link, the 10 seconds "hot reload" after a change... I'm on a M4 MAX with 64GB of ram....)

I have switched from the bloated mess of Nextjs to Vite+TSS and never looked back.
