TIL computers can sometimes grow crystals

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.

Training reactor that you can see though is pretty neat!

Apparently reddits nuclear subs are anti nuclear now, as they won't let this video be posted.

Livestream with more info about Kyle Hill videos beginning banned from nuclear subreddits. Discussion starts at about 17min in. https://www.youtube.com/live/LF-AMZYrLYs

Tianlong 3 booster static fire test lifts off instead

Scott Manley video, looks like the hold down claps may have ripped the bottom off the booster, allowing it to take off.

Solstice - 5

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.

We are still flying half a ship!

Another happy landing. I can't believe starship managed to land gently after burning half the flap off!

Walking stick for your hike!

Just make sure to return them when you're done! Maybe even add a new one if you find one.

The one I used was very nice. Has a nice heft all the way down, and was very straight.

Disable tracking on Chevy Bolt 2019

OnStar reports location and speed data to the car manufacturer. Sometimes they will sell this data to insurance companies to raise your premium, as several news stores pointed out a few weeks ago. I couldn't really find an advantage to OnStar, (I have my phone to call emergency services) so I disabled it by pulling it's fuse.

For my 2019 bolt, it's f31 in the instrument panel fuse box, just down and to the left of the steering wheel. The fuse box cover comes off when you pull it hard from the bottom.

I was able to find which fuse went to OnStar in the owners manual and labeled on the inside of the fuse box cover. You should be able to find it for your model car there too if it uses OnStar.

I did have the casualty of my speaker for calls and texts. I'm not able to use it right now. I'll see if I can dig in and reconnect it somehow, but we'll see.

Who knows that other into they're snitching back to GM, or what they could do in the future, so I recommend disconnecting it. Good luck!

Reentry looked so cool!

Amazing views, especially for live! I don't think we've ever seen reentry plasma on a live stream before.

PS, does anyone know how to get a direct link to a twitter video? I used to be able to through nitter, but that shut down. I can't figure out how to get twitter videos on lemmy directly now.

POSITRON JourneyMaker, upside Down Portable 3D Printer

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.

How much it costs to cut 1 metric ton of carbon emission with various methods for different global carbon emission levels

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, by Ruben de Vela, 2010

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

Which one would you choose?

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

The ornithopter design is absolutely fantastic

I love the noise it makes and how it manages to look like a helicopter and biology inspired. And the wing folded dive to get to the spice harvester is just fantastic.

TIL Bologna in Italy had dozens of towers built in the middle ages

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.
