Gold Isn't The Best Conductor So Why is it Used in Electronics?
You see gold-plated connectors everywhere, from high-end audio gear to spacecraft. But here’s the shocker: Gold is NOT the best conductor of electricity.
The Conductivity Leaderboard If we look at electrical resistivity (ρ) at 20°C, the "medals" for conductivity are actually swapped:
🥇 Gold Medal goes to Silver: The ultimate conductor (1.59×10−8 Ω⋅m).
🥈 Silver Medal goes to Copper: The industry standard (1.68×10−8 Ω⋅m).
🥉 Bronze Medal goes to Gold: Actually the least conductive of the three (2.44×10−8 Ω⋅m).
So why use Gold?
If gold is in third place, why is it the gold standard for connectors?

@AuthorGFAllen Yes, but it wasn't because of the book, but instead their hateful claims on social media.

@Microinteracti1 You should factor in the value of the thing on the ground that the drone was trying to hit.
English

Right.
So let me get this straight.
The most expensive military on the planet, a institution that consumes more money annually than the GDP of most countries, looked at a twenty thousand dollar drone and said, yes, the correct response to this is a four hundred thousand dollar missile. Twenty times the cost. They did the maths and thought, brilliant, let’s do that. Repeatedly.
And then, magnificently, one week in, they rang Ukraine. Ukraine. The country their own president had just finished publicly flogging in the Oval Office like a Victorian schoolmaster with a particularly dim pupil. Trump stood there, chest out, that extraordinary hair doing whatever it does, and announced to the assembled cameras of the world that Ukraine was absolutely the last country he would ever consider asking for help.
Seven days later, someone in the Pentagon picked up the phone.
The truly staggering part is not the incompetence. Incompetence is everywhere, it’s practically ambient at this point. No, what takes your breath away is the confidence. These people were not quietly embarrassed and privately regrouping. They were strutting. Full chest, full volume, telling the world how this was going to go.
It did not go that way.
Ukraine, the country they don’t need, is now apparently quite necessary.
Remarkable.
Stay connected,

@dr_destruction_ @FireFox_XB9R @KimKatieUSA How do you come to think that? First impression was 'This is AI' - as I thought. Did some research and found the news articles. Then thought, not a fake given the other evidence. How does that make someone a moron?
English

@KimKatieUSA Fake AI video.
Sorry but watch it in slow motion and you see all kinds of artifacts, including dust that spreads like water and clouds of debris piling up on shadows, not on objects.

These two Spanish towns sit just 25 miles apart across the Mediterranean, but reaching one from the other requires a 12,000-mile drive.

Ok let’s make this a non-political maths problem.
I go to the shops.
I want to buy a cauliflower and some cheese.
It costs £4.90 in total.
Two days later, I go to the shops.
I want to buy a cauliflower and some cheese.
It costs £5.10 in total.
I write to the press angrily that in 200 days, it will cost £24.90.
Why is this wrong?

@traskjd Sadly, I think the medical industrial complex is going to take a lot of effort to overthrow.

This Australian guy building a designer cure for his dogs cancer won’t go out of my head.
What exactly stops setting up this as a simple site, with steps necessary?
Thinking you could generate the result once necessary inputs are provided.
Heck you could even potentially hook it up to @karpathy’s autoresearcher to help iterate against the metrics that matter.
I appreciate that regulation will be the bottleneck that really needs defeating, but it’s seriously feeling like all the ingredients are already sitting on the bench.
We just need to assemble them correctly.

@Crypt2Equalizer @MichaelAArouet Oh c'mon. It's a real picture of a staged event in which DEI person has no clue.

@MichaelAArouet I hope it’s an AI image because that burn is gonna hurt for a long time.

@mysteriouskat So an individual member of the Nazi party should be... what?

@kgelner @ObtainerOf But it saddled with macOS Vista. Maybe wait for a bit.

@ObtainerOf New cheap MacBook just dropped, will do anything you want...

@aakashgupta They'd still have shit keyboards. Nothing beats mechanical.

The average laptop screen ships at 400 to 500 nits of brightness. Direct sunlight requires 1,000 nits minimum to be readable. Most MacBook Airs top out around 480.
So every person “working from the beach” is doing one of three things: squinting at a washed-out screen while cupping their hand over it like a visor, cranking brightness to max and watching the battery drain in 90 minutes, or posing for a photo with a screen that’s actually off.
The photo in this tweet is perfect. Two guys in white button-downs at a beach table, hunched forward, clearly unable to see anything. One has sunglasses on, which makes the screen even darker. The other is eating a bagel and appears to have accepted his fate.
The entire “laptop at the beach” aesthetic is a lighting trick. Every influencer photo is shot at golden hour or in shade. The second the sun is directly overhead, your $2,000 laptop becomes a $2,000 mirror.
Apple, Dell, and Lenovo could fix this tomorrow with 1,500-nit panels. They don’t because the battery tradeoff would cut runtime in half, and “4 hours of battery life” doesn’t sell in a commercial.
The remote work fantasy was always an indoor product sold with outdoor photography.

Being on your laptop outside is a miserable experience and im tired of people pretending it's not

@MoElleithee Kind of proves his point though. If your religion compels you to kill your neighbour for saying such things, your religion doesn't belong in American society.
English

“It does me no injury for my neighbour to say there are twenty gods, or no god. It neither picks my pocket nor breaks my leg.”

Muslims don't belong in American society. Pluralism is a lie.

@FnMiddle @liv2cod @folaoftech are u talking about gwt or in general? in my experience gwt offers way too little flexibility to be good for frontend
English

@liv2cod @folaoftech Java was originally intended for front end, but never caught on.
English
@folaoftech Yeah, this is not my experience. I'm more accustomed to the female developer who is promoted to "senior" level with 3 years experience, ahead of men with 10 years or more. JavaScript is for front end, but can be used in backend too.
