@thekitze The real reason for hating drive EV in Poland is not the number of supercharger, but simply the fact that Poland produce the most carbon intensive (coal) electricity in EU. With the PER, it makes EV much worst than any thermic car.

@Steve_Yegge It seems work is endless with Opus. There's always something more to do, something wrong to fix, and it seems to fall easily in fix-on-fix loop.

@gilgNYC Don't you guys in US still have access to Fable?

@EPhilippe_LH Notre énergie décarbonée!?
Vous avez fermé Fessenheim !!

@mattshumer_ @RZ0224 Show us?

[Rodolphe Jacson @RodJacson]

@mattshumer_ 100X may be not.
But there is a gap, that's clear.
Now back running Opus 4.8 and Codex 5.5 and the feeling is quite not the same.

@GonesArea @Le_Hug38 C'est surtout le pousser vers un club qui ne représente pas une forte progression pour lui. Je comprends qu'il ne veuille pas y aller.

[Rodolphe Jacson @RodJacson]

Now that I'm forced by the US government to go back to @claudeai Opus 4.8, I can say Fable 5 was much better.

Will switch again to @OpenAI Codex to see if I feel the pain here as well.

@steipete 😂

@levelsio Disconnected by the US government for non US user. I thought I burnt my limit but this was geopolitics.
Back to Opus this morning.

We went from 0 to 2,200 paying customers in under a year by following @ycombinator's 15 rules:

1/ Do things that don't scale. Get your first 10 customers by hand.

2/ Launch now, not when it's "ready". A mediocre product in front of real users teaches you more in a week than 6 months of polishing in the dark.

3/ Charge from day one. If nobody will pay, you don't have a startup, you have a hobby.

4/ Talk to users every single day. The roadmap you need is sitting in your customers' heads, and they'll hand it to you for free

5/ Always hunt the 90/10 solution. For almost any feature there's a way to capture 90% of the value with 10% of the effort.

6/ There are only two real jobs: write code and talk to users. Everything else (conferences, press, VC coffees, corp dev calls) is fake work.

7/ You pick your customers as much as they pick you. 10 users who love you beat 1,000 who kind of like you.

8/ Growth is an output, not a strategy. Grow before product market fit and all you're buying is churn.

9/ Do less, really well. Pick one or two metrics and judge every task against them.

10/ Know if you're default alive. Paul Graham's question: on current growth and current burn, do you reach profitability before the money runs out?

11/ Don't hire until it hurts. Headcount is not progress, it's burn. Every great startup was embarrassingly small for embarrassingly long.

12/ Momentum is the only real moat in year one. Ship something every week, even something tiny.

13/ Every great startup is badly broken at some point. The game isn't avoiding fires, it's how fast you put them out. Again. And again

14/ Ignore your competitors. Startups die of suicide, not murder. In year one, the only company that can kill yours is your own

15/ Startups rarely die from running out of money. They die because the founders fall out. Brutal honesty with your cofounder is the cheapest insurance you'll ever buy

Good luck !

@jackfriks Your migration made them crashed!😲

[How To Prompt @HowToPrompt__]

A toothpaste company has quietly killed the entire market research industry and nobody is talking about it.

Colgate published a paper showing you can predict real purchase intent at 90% accuracy by simply asking LLMs to roleplay customers.

And this is beyond insane.

If you ask an AI, "Rate this product from 1 to 5," it gives safe, middle-of-the-road garbage.

So researchers invented a method called Semantic Similarity Rating (SSR).

Instead of asking the AI for a number, they asked it to roleplay.

They gave the LLM a demographic profile. They showed it a product concept. And they asked it to write down its raw, unfiltered thoughts.

Then, they used a semantic model to translate those written thoughts into a numerical score.

The results are staggering.

Tested against 57 real corporate surveys and 9,300 actual human responses, the synthetic AI consumers matched real human buying behavior with 90% reliability.

They perfectly mirrored how different age brackets and income levels react to price changes.

And they provided detailed, qualitative feedback that was deeper and more critical than what actual humans wrote.

This destroys the economics of traditional market research.

You don't need to wait a month to see if a product will sell.

You can simulate 1,000 hyper-targeted customer interviews overnight.

You can A/B test pricing across every demographic instantly.

@Squid0ne @Samsung @SamsungFR Je l'ai fait plusieurs fois mais ça revient...

[Rodolphe Jacson @RodJacson]

Hello @Samsung!
@SamsungFR seems too busy to reply. Can you help me?

[Rodolphe Jacson @RodJacson]

Hello @SamsungFR depuis une récente mis a jour de ma télé j'ai cet écran qui revient constamment : le bouton continuer sans accepter ne fonctionne pas.
Aussi depuis cette maj télé s'allume sur RakutenTv par défaut. Comment revenir à la dernière chaine regardée par defaut?
Merci!

[Rodolphe Jacson @RodJacson]

@felixrieseberg @ARomeoSierra Cool! You're using a kind of open API or developer mode that La Marzzoco has?

[Rodolphe Jacson @RodJacson]

@ARomeoSierra @felixrieseberg I think it is just displaying the le marzzoco mobile app?

[Rodolphe Jacson @RodJacson]

@bijanbowen I love the laptop!
