You don't ask a lady that. How rude.

Is there a website, or...? Purely scientific interest.

What? In the bottom board, assuming white to move, any capture is a checkmate - black king cannot escape check, and cannot capture because the pawn is supported.

White wins in 1 move.

That is scenario 1, where the single pawn can't see all the other pawns, blinded by all the frivolous stuff.

Scenario 2 is checkmate in one move, take a horse with any pawn and it's smothered mate - the king dies, suffocated by the sycophants around him that are powerless to defend him from the pawn avalanche.

A really good metaphor.

Oh damn, what up with the big man? I've been so happy to see Hamilton having fun behind the wheel again, let's hope it's nothing serious and doesn't change the current trend.

I was considering it might be the only reason I'd buy a gun.

Fuck that duck is me right now, and probably for the whole of 2 more days.

This confuses me a lot. Here you're either blowing into that breathalyser, or you're getting escorted to the nearest hospital for a blood test (you can collect your car later at the impound after paying the ridiculous fee).

A gymnastics course in the middle of the night off the side of some road is just awkward.

Used to be just the IRS.

In prison? This man deserves a fucking statue, and that we do the same to him when it's his time to go, send him off with the party of his lifetime.

It's been a minute since Boeings stopped failing spectacularly, so it's a mild surprise, but for a new plane's landing gear to collapse while parked, it reeks of manufacturing defect and QC failure...

Thankfully it failed when parked, things could have turned out much, much worse if it had been later during landing...

This is a purely theoretical exercise, from what I could understand:

[They] considered what would happen if a single photon passed through an optical shutter—essentially a very fast mirror that can be switched on and off to block part of a pulse of light. If the shutter was fast enough, it could intercept the photon mid-pulse, snipping off part of this extended wave.

They then did a bunch of calculations to simulate what would happen, but I'm wondering if such a shutter wouldn't have to travel at the speed of light to catch the photon, and if this doesn't make the experiment meaningless...

 

Just saw the post about Helsinki opening several bridges for a similar purpose, so thought I'd share this here as well.

Porto Metro system didn't exist until around 20 years ago. Just last year, it carried more than 90 million people, and it's not stopping.

While traffic in Porto has actually gotten worse, as tourism and building rehabilitation have exploded, the investment in the metro continues.

This bridge is part of the new "Ruby line", and will provide another much needed way of crossing the Douro river, and will be exclusively used by pedestrians and cyclists, along with the metro.

This line is great because it will connect the other existing lines to a university campus and a large shopping center, while serving a fairly high density area where the residents mostly work in Porto, and have to commute daily.

 

Hi everyone!

I'm trying to control a "dumb" led light strip segment with an ESP-01S. This is fairly low current, the strip will pull 150mA-200mA max (depends on... artistic? needs).

I have two NPN transistors (2N2222), one to control the 12V supply to the white "channel" and the other the red+blue (don't need the green).

I had to pull-down the gates as I had some flickering, and it works perfectly if I manually connect the GPIOs after the ESP-01S boots.

The ESP will boot if I have the RX pin (GPIO03) pulled down on boot, but not if I pull down any of the others.

I'm not smart enough to come up with a way to have that extra pin I need to be high only during boot, while the gate it's attached to needs to be pulled down...

Any thought, other than getting something with more IO pins?
