A Mohana hunter holds a branch with a living bird tethered to the end, which he uses as a decoy to trap wild birds. The caught birds are either sold at the market or used as food for the family. The Mohana people once thrived on Lake Manchar in ’s Sindh province, but pollution and drought have caused the fragile ecosystem to collapse, along with their way of life.

The jaguar had been rescued by military personnel while swimming in the Negro river in October after being shot in the head by illegal hunters. It underwent surgery to remove the bullets and, after making a full recovery, was reintroduced into the wild.

So Chinese hospital ships are now in the Carribean, helping Jamaica.♥️🕊️

It's fascinating that we're all getting front row seats to see if threats and violence (US approach), or compliments and assistance (Chinese approach) will be more effective by 2030 at securing resources from developing nations.

Prior to the 21st century, the most effective way for an empire to build wealth, was unquestionably "Kill the Black and brown people, and steal their stuff."

The empires growing weath the fastest, were the most belligerent. Dutch. British. American.

But in the 21st century, that's less effective.🤷🏿‍♂️

In the 21st century the superpower growing wealth the fastest, is by far the least belligerent, least imperial, least colonizing.

(I didn't say zero violent or zero colonizing. I said least. If you've never taken even one African history course or lived on the continent, don't try to speak on this)

Shout out to everyone that will misread this as being pro-China. This has nothing to do with China. Americans, this has 100% to do with us.

You can't change another nation's approach. You can only change your own.

We can't stop their hospital ship from docking. But we can send ours.

Compete.

2.

"The law of war is a delusion designed by great powers by their servant lawyers & diplomats so that it will never hinder their military ambitions."

"There's so much wriggle room... by the major powers... that their own troops will, by & large, not fall foul of it."

Eg, Nuremberg didn't prosecute Göring for bombing civilians, bcz "they were afraid he'd run the 'You did it too' defence."

"Bcz there's no clear law against it."

lesson 6: What goes on inside a lock?

A (typical pin tumbler) lock consists of a pretty simple mechanism. Pairs of pins—the driver and key pins—are pushed by a spring, such that the driver pins block the core of the lock from rotating. When a key is inserted, it raises the pin-stacks so that the driver pin is above the shear line between the core and the lock housing, and they key pin is below it. Key pins are different lengths to compliment the bitting of the key, so that they all end up being the same height when resting on the cuts in the key.

In picking a lock, we simulate the key by manipulating the pins manually.

Locks are only pickable because manufacturing is imperfect. *Ideally* the pin chambers would be perfectly identical and in a perfectly straight line. *Ideally* the pins would be perfectly smooth and identical in all but length. But that's never the case. And we can use that fact to our advantage.

When we apply rotational force to the core of the lock with our turning tool, it causes the pin-stacks to pinch between the core and the housing. The pin closest to the direction we're turning will get pinched the hardest. That's the one we're looking for. When we lift that pin with our pick, it scrapes against the pin chamber until it reaches the shear line. Once it's set correctly, the next closest pin will bind, and so on. It's the same pinching that causes the set pins to stay in place—they rest on the lip of the core's chamber. Once all the pins are set, nothing is blocking the core from turning, and *click* the lock opens.

When you lift a pin too high, you "overset" it, which means the key pin is now the thing being pinched, rather than the driver pin. This'll result in a mushy, dead feeling in the pin. It'll go up, but won't spring or fall back down. It also means other pins won't bind, so everything just feels kind of lifeless in the core (like we do under capitalism).

If you *ease* off the tension, then eventually a pin will drop back down. With any luck, it's the overset one. Reapply tension and poke around to see if a pin is binding nicely If not, ease off tension again until another pin drops. This is how you recover from a misstep while picking. If you have to do this more than once or twice, consider dropping all the pins and starting over—because you've probably lost your mental image of the lock's state and it'll be better to start clean.

CatSalad's interpretation of me getting ready to probe a petite French Louis Vuitton padlock with my tension tool. You can really see the tension on the lock's face, and I can feel a new adult anime series in the works.

Any chance you have six Cisco-branded UCS-MR-1X162RU-A 16GB memory modules?

I bought two for a community system for around $21 each before EuroBSDcon, verified that they worked, now have a moment to “buy more” but they’re now $40 each, because AI.

In Gaza, more than 70 children have been reported killed since October 10th, when the world hoped the relentless violence and distress for more than one million children would end.

A ceasefire must translate into genuine safety for children, not more loss.

“Every child has the right to live. The killing of children must end now.”

UNICEF
