Ball headbasher to ballgnasher is a quick chomp.

Yes, that's the second arc.

In the first accident there were no half-spheres, the neutrons were being reflected back using bars of tungsten carbide placed around the exposed core.

Wiki photo from a recreation of the first incident:

In the second accident, a year later, the reflective material was the two beryllium half-spheres. Shims were used to ensure the two halves were never fully closed, which would trigger the nuclear chain reaction.

Supposedly, this guy liked to show off and had done this demonstration a dozen times in front of different audiences, wearing jeans and cowboy boots and using his screwdriver instead of the shims.

Some report that Fermi told the guy and others that "they would be dead in a year" if they kept doing that... and voila.

The good thing is that he at least was hunched over the core, so he mostly shielded everyone else in the room from the worst of the radiation by absorbing it himself. 9 days later, he was dead. The guy closest to him was in the hospital for several weeks with severe radiation poisoning, but at least survived but died fairly young, in his 50s, which may or may not have been related...

Nobody should be barred from posting their art online, even if it's abysmal, as long as it's actually theirs.

Here's my 15 second, god awful taco:

That's the brilliant part.

They were led to believe the government could go after them physically, and that's what they're looking for, while they steal their healthcare and education and infrastructure, while deporting the cheap labor they were exploiting in their farms and depriving them of income.

They're tightly watching their front door, ready to shoot the first person getting close to it, while the rest of their house is being robbed blind...

How will they exploit their position for profit though? Selling policy to the highest bidder like a regular corrupt politician? Pff have some class will you...

That was hilarious. Also kinda spooky to think that, if Japan hadn't surrendered, Demon Core-kun would have been the 3rd nuke dropped over them.

The cartoon only covers the second story arc though, the one with the screwdriver.

In the first arc, the core is "nude" and they're stacking neutron-reflecting bricks around it to bring it close to criticality. A scientist drops a brick by accident on top of the core and boom, blue light and you're dead (takes 2 weeks for your body to notice though).

This isn't hard, you're just trying to make it to be.

Memcpy from a file to a screen buffer is as much a UI as pouring water in a pot is a soup.

I never understood the fixation on IPs. For a kick ass universe with amazing lore etc, ok sure.

I mean I love Jeb and the gang as much as the next guy, but they're not core to my enjoyment of KSP1. The mechanics were.

Ah I missed that, sorry. But that's hilarious, I can imagine the Republican-level mental gymnastics that many democrats are now required to pull off so they can still support Cuomo.

I think you're right and that is how the word is most often used, but at least merriam-webster gives a broader definition, as the "practices or pretensions of a quack", which it then says is the same as a charlatan, so I guess it would be acceptable. I'm not a native speaker, however... :)

That's because it's lifted from an actual security flyer, edited for funnies.

The original is probably this:

 

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?
