epolanski··on Claude Haiku 5.5
"companies" is a meaningless metric.

If you want to make it about 99% of real world companies, they are all on Gemini or Copilot anyway, nobody is going through legal and procurement to get models from dubious silicon valley startups when you have relations with Microsoft or Google or Amazon from ages because some benchmark is showing some minor digit benefit when vibe coding GTA 6.

Doesn't matter, it's excellent, and it's European with European inference, which solves the pains of all my clients trying to build data lakes and processes on top of it.

Nobody in the real world cares about minor benchmark differences in money losing coding agents.

And nobody in the real world is giving Altman or Musk their data.

This isn't 2016 anymore.

To me this feels the worst of both worlds.
epolanski··on JetBrains reports revenue growth, net financial loss for 2025
I'm slowly accepting that this is the new reality.

I've spent 1 month between august and early september writing some of the best code of my life. LLMs only provided feedback, I wrote all the code manually, still remember it by heart.

I was very delighted by the many architectural iterations that led to it. 9 files, around 10k lines of code (of those, 7k tests).

By the end of super funny exercise I kinda realized that if I had the same feature vibe coded it would've been better. I would've done much more and progressed more feature wise.

I just feel stupid hand writing my code.

It doesn't help that I work with stellar individual contributors. All of my team mates (except a junior) are either all former faang or contributed to projects we all use (from the TypeScript compiler to Linux). And they are all abandoning if not spearheading the abandonment of reading code. I'm talking people that truly loved the technical aspect of it and excelled in it.

I just feel stupid, like I'm carrying a weight that I should abandon.

Comments like yours feel would've made sense 6 months ago, but now are crumbling.

Software is essentially so cheap and throwaway nowadays that letting LLMs write it is imperative. When you find your use cases you start reviewing it or rewriting it thoroughly.

Eh, that is the nostalgia ignoring how many crap seasons we had by the end of the previous regulations and how unbalanced F1 used to be.

epolanski··on Why don't more developers “use the platform”?
The first react implementation was done in OCaml, it was ported to JS later.
epolanski··on Why don't more developers “use the platform”?
1. Because most developers are unskilled and don't even know the platform.

2. Because very few companies out there have a quality over quantity metric.

3. Because developers are very hard to change technologies once they get in the comfort zone.

4. Because LLMs keep shoving the same inefficient tailwind react crap everywhere.

epolanski··on From the creator of Redis; run LLM locally with ds4
Antirez understood the fundamentals of how LLMs work, and read the inference code (or summaries of it via ai).

But what really made the difference was his understanding of hardware and systems programming in general and low level or architectural tricks to pull.

epolanski··on Gemini 4 Argon (High): Intelligence, Performance and Price Analysis
Companies out there are on google cloud or microsoft offerings and getting Gemini in their bundle, they aren't going through lawyers, etc, to provision from Anthropic or OpenAI just because they look a bit better on nerd benchmarks.

The problem with benchmarks is that they are end to end.

You go from one prompt to the final solution, whereas for many of us it is about the experience of iterative, multi turn working.

epolanski··on California farmers are struggling to sell grapes as demand for wine drops
The people commenting are also consumers, as are their families and friends.

So anybody may have their own take from their experience of what's happening.

I myself drink much less wine as is my inner circle so I have an opinion.

epolanski··on Toyota is taking the Corolla electric
We don't have materials, we don't have energy.

Not sure how are we supposed to thrive in a world where cars are very simple and our know-how is borderline useless.

Imho cars are a dead race-to-the-bottom business, that was true in ICE world, that will be even more true in the electrified/autonomous driving one.

epolanski··on Toyota is taking the Corolla electric
> All of Europe is now buying EVs like crazy.

In my country, Poland, 40'000 EVs were sold last year.

Toyota sold 106'000 cars.

People keep saying that Toyota is doomed since 2019, but numbers don't show that.

If anything, numbers confirm Toyota's strategy was right: play it slow and cool, and start shifting into EVs when a huge EV market will exist.

EVs really need no FOMO. They are simpler beasts to build than ICEs.

epolanski··on Toyota is taking the Corolla electric
There was no arrogance.

Incompetence maybe, but no arrogance.

European governments and companies are like ships that change captains, while the direction of the ships is hard to change due to inertia.

Politically, I'm happy for this, on a business level, not really.

epolanski··on Toyota is taking the Corolla electric
I love this non sense fear mongering.
epolanski··on Toyota is taking the Corolla electric
This has been said so many times, yet Toyota's sales keep growing and incumbent EV makers plateaud.

Except Chinese ones, of course.

epolanski··on Rails World 2026 Opening Keynote [video]
I want to agree with you, at heart I do, but:

1. AI is exposing the harsh truth that 99% of the code out there has always been throwaway code. Yet good developers, void of any engineering skill, treated it like the 1% that wasn't and called their hygiene and practices engineering.

2. Way too many developers that have made their careers or internet fame out of their technical proficiency understand that the shift is unavoidable. See Antirez implementation of Arrays in Redis or his Dwarfstar project. Virtually every line of these projects has been AI authored. And yet they are terrific projects with extremely strong architecture. And not a single line was edited in vi (his favorite editor).

epolanski··on The Mafia may be keeping fentanyl out of Italy
A better representation of real Italian mafia in movies is offered by the TV show Gomorrah.

It's a strong antidote to those romanticizing crime.

In US it should be available on HBO Max.

https://en.wikipedia.org/wiki/Gomorrah_(TV_series)

The first two seasons are great, watch it with subtitles (fun fact: in Italy it was also shown in tv with subs because most people cannot understand neapolitan dialect).

epolanski··on Italian parliament votes for return to nuclear energy
> Asking once every 15+ years seems fine, the population changes and opinions change.

But nobody asked, there hasn't been a third referendum.

epolanski··on Italian parliament votes for return to nuclear energy
I am not debating the benefits of democracy, rather how there's no democracy at all if a referendum is not legally binding and a government can disregard the result.
epolanski··on Italian parliament votes for return to nuclear energy
> after voters *twice* rejected it in national referendums

Democracy is just lovely.

Have your citizens answer to a straightforward question on a topic twice, have them reject it, both times.

And the government will still go its way.

I'm not against nuclear per se, I'm just baffled at the "democratic" process.

epolanski··on Socialism's Positive Rating Tops 40% for First Time
As an European I always found your left very conservative.

In the most recent years I feel the same about our lefts.

But imho left/right don't make any sense any more and have very little connection to their historical roots.

Look at how the conservative party went into ballooning the debt and spending, something they have been historically very against. Or how European rights are more financially supportive of the poorest parts of the society than the lefts.

Policies and trends are changing.

Yet we're stuck in this nonsense bipolarism when every other adult has many thoughts on many topics that don't really overlap with either of the two poles.

epolanski··on The Price of Intelligence Is Falling Rapidly
I went from 408 euros/month of AI spending to 28 in the span of one year.

The 20 euros GPT plan with GPT 6 Luna (and Astra for doing the tough stuff) and OpenCode Go (8 euros) offer me both way more intelligence and tokens than spending 400 euros just at the beginning of the this summer did.

Today I worked two hours with GPT 6 Luna, have been very productive tackling some hard stuff and...my weekly usage went from 57% to 56%?

You really don't need to use the strongest model for everything. And even chinese open models are effectively few months old sota. You can use mimo 2.6 or DS 4.1 flash on 8 $/months OpenCode and barely ever have to worry about consumption.
