Did you take him seriously when he said sending cruise missiles to Ukraine would be considered a nuclear attack? Or that sending f16s would be a nuclear attack? Or when he said Ukraine was planning to use a nuclear dirty bomb? He has every incentive to blow everything out of proportion, so we can't go off of what he says.

Mechanical Hand Testing (www.youtube.com)

Ian Davis has been working since he lost his fingers to design and build a mechanical hand. He's now looking for other amputees to help him test the design. It's a really cool project, I love following his progress!

Op Sec was fantastic from Ukraine. With that and Russia ignoring what info on troop buildup they did have, they managed operational surprise.

Tin in solder or some other meals can form spiky crystals when under stress. These whiskers can form short circuits if not properly insulated or not alloyed with other metals.

I wonder how many times this needs to be reposted and downscaled to no longer be true. It looks like this is already not the original resolution of the picture.

Solstice - 5 (youtu.be)

Stunning short film. Seems scarily plausible, we won't lose control of AI, the people in change just won't care enough to control it.

Crypto trade

There's where all the money went I guess. Gotta steal toilet paper to leverage that crypto position. (After you've already lost everything several times)

Star wars a new hope started out with Luke as an everyman. But since then it's all become about the bloodline. Rise of Skywalker is especially bad, tearing down the anyone can be special and saying you can only be special because of your bloodline.

Without nato membership, nothing prevents Russia from trying again once they've regenerated their forces. Russia has already broken their promise to

reaffirm their commitment to Ukraine, in accordance with the principles of the CSCE [Commission on Security and Cooperation in Europe] Final Act, to respect the Independence and Sovereignty and the existing borders of Ukraine

So Russians pledges are worth less than nothing.

They're also recruiting from prisons and promising freedom afterwards, right? That probably doesn't help.

Folds down to fit inside a 1kg filament box. Upsidedown let's the complicated moving bits be in the base where there's less vibration. Krylan3D originally designed this to easily take in a backpack back and forth from college, but is now hired and working on designing other 3d printers. So the community has made improvements and made it easier to make yourself. Parts cost about $550.

Last time I checked, corn flakes weren't that cheap. My go to is still rice.

As you reduce the amount of carbon emissions (the y axis) the methods to keep reducing carbon cost more (the x axis.)

This great graph came to my attention from this video from vlogbrothers. It also has some good explanations of what it means.

Note that carbon capture doesn't really make sense till you've exhausted all the other emission minimizing methods.

Ancalagon the Black, the absolutely gargantuan dragon from the first age of middle earth!

This fantastic artwork is by Ruben de Vela. I think the sense of scale and immense power are remarkable.

But Earendil came, shining with white flame, and about Vingilot were gathered all the great birds of heaven and Thorondor was their captain, and there was battle in the air all the day and through a dark night of doubt. Before the rising of the sun Earendil slew Ancalagon the Black, the mightiest of the dragon-host, and cast him from the sky; and he fell upon the towers of Thangorodrim, and they were broken in his ruin. The Simarilian chapter 24

It can't be that hard, it's only two questions!

Which one would you choose? (external-content.duckduckgo.com)

A lightsaber stick or sword stick would also be an acceptable choice

There's a war going on right now in Ukraine, helping them win it will make Russia launching a next war less likely and further off.

These mini castles were built all over the city.

The reasons for the construction of so many towers are not clear. One hypothesis is that the richest families used them for offensive/defensive purposes during the period of the Investiture Controversy.

Only a few survive to the current day.
