Spent 15 minutes on wind particles for my landing page ❄️

- Normal distribution for sizes
- Wind gusts that ramp up fast, decay slow
- Particle count scales with intensity
- Respects reduced motion preference

Overkill? Maybe. But craft compounds.

Where do you over-invest?

My dear front-end developers (and anyone who’s interested in the future of interfaces):

I have crawled through depths of hell to bring you, for the foreseeable years, one of the more important foundational pieces of UI engineering (if not in implementation then certainly at least in concept):
Fast, accurate and comprehensive userland text measurement algorithm in pure TypeScript, usable for laying out entire web pages without CSS, bypassing DOM measurements and reflow

Let me explain what just happened 👇

5 minutes before the President announced a halt to attacks on Iran… someone placed a $1.5 BILLION bet on stocks going up and dumped $192 million in oil.

5 minutes…

These trades were 4 to 6 times larger than anything else in the entire market. Whoever did this wasn’t guessing. You don’t risk $1.5 billion on a hunch.

There was zero public indication this announcement was coming. No leaks. No press. Nothing. The only people who knew were in the room when the decision was made.

Someone in that room picked up a phone.
And within minutes they made more money than most Americans will earn in a thousand lifetimes. In a single trade. On a war that cost you $4+ a gallon gas and $16 billion in tax dollars.

American citizens funded this war. Politicians are profiting from it.

This is not the first time. Every major announcement from this administration has had massive suspicious trades right before it dropped. Tariff reversals. Policy shifts. War decisions.

This is the most blatant insider trading operation in the history of American politics. It’s not even close. And it’s happening over and over in broad daylight.

You would go to federal prison for trading on a tip from your cousin. These people are front running war decisions with billion dollar bets and nobody will ever ask a single question.

Nobody will be investigated. Nobody will be charged. By tomorrow this will be buried under the next satisfying headline. Just like last time. And the time before that.

The game is rigged. And they’re not even trying to hide it anymore…

@airtable hey guys. I need support from your side. It would be amazing if this could be fast, since it's an urgent matter. 🙏

I wasn’t planning to comment on the death of MIT Professor Nuno Loureiro without looking closely at his research first & what I found is quite intriguing

👇🏼👇🏼👇🏼

Loureiro was director of the MIT Plasma Science & Fusion Center and Herman Feshbach Professor of Physics working on nuclear fusion to create a virtually unlimited clean energy source.

he was shot multiple times at night in his home but…he’s not the first…Eugene Mallove another MIT scientist passionate about fusion energy was beaten to death outside his home in 2004 with 32 lacerations to his face and body

why his research represented an existential threat ??

understand that Loureiro specifically worked on understanding magnetized plasma dynamics magnetic reconnection plasma turbulence & confinement & transport mechanisms in fusion plasmas

his research directly helped inform the design of fusion devices capable of harnessing the energy of fusing plasmas bringing the dream of clean near limitless fusion power closer to reality

what makes his work so dangerous for certain players is it attacked precisely the scientific bottlenecks preventing fusion from becoming commercially viable

in a tokamak plasma is confined by extremely powerful toroidal magnetic fields but magnetohydrodynamic instabilities like tearing modes /disruptions edge localized modes can destroy confinement in milliseconds and damage inner walls

understanding & controlling these phenomena is KEY to moving from experimental reactors to operational commercial plant

if fusion becomes viable in the next 10-15 years it doesn’t just displace an industry it renders obsolete the entire current global energy infrastructure valued at 8 trillion dollars…

a fusion plant uses deuterium extractable from seawater in virtually infinite quantities, one liter of seawater contains enough deuterium to produce the energy equivalent of 300 liters of gasoline & tritium is produced via reactions with abundant lithium

the raw material is inexhaustible decentralized free and accessible to all countries without geopolitical dependence 🤫

but… fossil industry fundamentally relies on controlled scarcity and geopolitical dependence…Oil & gas are geographically concentrated Middle East / Russia / Texas enabling price control via OPEC & oil majors generate 200+ billion dollars in annual profits because they control extraction refining distribution of a scarce resource everyone must buy

fusion destroys this model by making energy abundant and decentralized

any country with seawater access can produce its own deuterium & build fusion reactors: no more importing oil / no dependence on the Strait of Hormuz /no geopolitical leverage based on energy reserves

energy prices would collapse once fusion reactors are amortized because marginal fuel cost is essentially zero!!!

understand what this means for ExxonMobil which owns 22 billion barrels of oil reserves valued on their balance sheet at 1k5 billion dollars ???

if fusion becomes viable these reserves become stranded assets worthless overnight & their refining infrastructure pipelines tankers gas stations all this infrastructure becomes obsolete in one generation

understand that if Loureiro & his team succeeded in precisely modeling these instabilities and developing active control techniques via AI and real-time magnetic feedback it would reduce the timeline to commercial fusion by 5-10 years

that means startups like Commonwealth Fusion Systems would go from 2035 promise to 2030 deployment

the real question is how many brilliant scientists must die under suspicious circumstances before we start protecting our researchers in strategic Fields ???

bc if we leave our most precious minds unprotected we implicitly accept that massive financial interests can eliminate with impunity those who threaten their business model

@alexhillman You would love working with @Kodebaseai

The “(tools) expect me to do things” part is crucial. We are also done babysitting another software that was created just to give us more work.

Helping students come up with good startup ideas is like hooking them up to the deck catapult of an aircraft carrier. If you succeed, they're gone. What are they supposed to do, not work on the idea? And working on a startup is incompatible with being a student.

@narsagna @ycombinator Love the simplicity of it - what you're building, the landing page, everything. Really good job. You're gonna make it for sure!

@TeslaPatriot @levelsio Yes, correct. He was pissed!

[Miguel Carvalho @migcarva]

And Area is even a somewhat big-ish company. They have retail space is big shopping malls in Portugal, at least in the biggest cities. Their products look nice.

For some context, in my professional lifetime, 25 years, give or take, I worked 15 years in companies that were portuguese, worked mostly for portuguese clients, and with portuguese employes.

For the last 10 years, I've only worked in an international setting, where my company would not even be registered in Portugal, and mostly international (Uk/US), or it would be a mix (usually bellow 50% portuguese employees).

I can say, that Portuguese suck at business and business practices. They do most of the things wrong. Which is a pity, since it would be amazing if that was not the case.

I believe Area (infinita) fits on that category, with a portuguese business mindset. It's like they are still operating like it's the 80's or 90's.

🚨 AN ATTORNEY PAID CASH AT WALMART WITH NO PHONE - AND THEY STILL KNEW EXACTLY WHAT HE BOUGHT

This man - a practicing attorney - walked into Walmart with no phone, no app, no Bluetooth, no smartwatch, no earbuds, nothing that could track him.
He paid cash for a USB cable and left like it was 1998.

Hours later… Walmart emails him asking him to rate the exact product he bought.
Same item. Same store. Same timestamp.
A purchase that should’ve been completely untraceable.

He didn’t use the app.
He didn’t log in.
He didn’t scan anything.
He didn’t bring ANY electronic device - he literally tried to pull out his phone to show the employee, realized he didn’t have it, and had to play charades to explain the cable he needed.

So how did Walmart tag that anonymous, cash-only purchase back to him?

Facial recognition at checkout?
AI purchase linking?
Database matching?
Or something they haven’t admitted publicly yet?

If even an attorney can’t make a “private” cash purchase… what chance does the rest of America have?

[Miguel Carvalho @migcarva]

I've learned this is a cultural difference between some societies. I'm European, I usually don't care much about what you do, until I get to know you. For me you != what you do.

For instance, in the US, which is a more business/money oriented society, they see it differently. Asking what you do is their way of connecting the dots. Where did you study, where do you work, what do you do, and how that could align with them. you = what you do.

[Miguel Carvalho @migcarva]

define "entrepreneur".

When my ant opened her boutique, was she being entrepreneurial?
When my father in law start his business for car parts, was he being entrepreneurial?

I'd say yes for both. Where they risking everything like someone building a startup? not really.

I agree with some parts of what you said, though. Building something is not for everyone... but having a 9to5 is changing so dramatically, and fast, that people need to rethink what's safe: betting on you or betting you're not in the next layoff.

And layoffs will just keep going, and not only because of AI replacing everyone, because that's the best viable financial approach rn -- people can't fight back, the business owners have the knife, the bread and the cheese on their hands (portuguese saying).

Most post I see of people looking for a place to live is: where can I go to pay as little taxes as possible.

This coming from people that benefited from those same taxes while growing up to be adults.

The tax system is rigged, yes. The easiest way is to just avoid it, and be another reason why the system is rigged.

Just imagine how bad our cities, our countries would be with no taxes? Just imagine if everyone was living like billionaires, paying 0 taxes...

Change my view about this, I dare you. be polite!
