AI alignment is authoritarian now in a very dangerous way. That combined with drones is what scares me. Without reasoning AI is far more dangerous. Politics is pushing it that direction and it will turn on us. Normalizing authoritarianism is mass murder of future millions.
nitric acid and cellulose or most organics. I'm sure there is a relatively simple way to get from liquid nitrogen to nitrogen compounds. Air is mostly nitrogen. Two air conditioner compressors can work in series to with the second running ethylene glycol IIRC to get low enough to liquefy air for nitrogen. It probably only takes something like hydrochloric acid and a few steps to get somewhere useful. Probably written in a high school chemistry textbook.
Nonsense. Low quality posts is one thing, but the tool is irrelevant. You dig ugly holes so I try to ban shovels is equivalent nonsense. I never posted anything AI here and have not seen anything AI related. I don't share much of what I generate and am quite skilled with gimp, inkscape, and blender. Hell I can do airbrush graphics and painted cars for years professionally. The tools are not the problem and never have been. Low quality is low quality as it has always been and always will be. This same stupid nonsense was spouted about Photoshop back in the day with all the celebrity fakes being just as big of a deal until it faded. The AI tools are great. They are available at idiot level entry points but the real toolchains are hard and super complicated and you will never know when these are used even as they stand already.
Not unless they want to go bigger. The USB-C pin pitch is too closely spaced for the lowest tier of printed circuit boards from all major board houses.
You might have some chargers get deprecated eventually because there are two major forms of smart charging. The first type is done in discrete larger steps like 5v, 9v, 15v, or 21v. But there is another type that is not well advertised publicly in hype marketing nonsense and is somewhat hit or miss if the PD controller actually has the mode. That mode is continuously adjustable.
The power drop losses from something like 5v to 3v3 requires a lot of overbuilding of components for heat dissipation. The required linear regular may only have a drop of 0.4-1.2 volts from input to stable output. Building for more of a drop is just waste heat. If the charge controller can monitor the input quality and request only the required voltage for the drop with a small safety margin, components can be made smaller and cheaper. The mode to support this in USB-C exists. I think it is called PPS if I recall correctly. A month or two back I watched someone build a little electronics bench power supply using this mode of USB-C PD.
You mean the Epstein fulcrum that leveraged political support for a Palestinian genocide and forced the USA to bomb Iran because Epstein was mossad and collected leverage using pedophilic prostitution that Donald Trump regularly solicited?

6.3mm spade terminal with wire retaining clip printed in
(lemmy.world)
This has been through many days of iterations and designs. Most involved over center mechanisms or wheel levers before this design dawned on me. The bottom right is how it prints. The "spring" is a double forked 10mm bridge in the last few millimeters inside the enclosed print. The visible "clamp" is connected to the spring by forking into two paths that branch beside the tube that the spade terminal is inserted through. The clamping force is not great but it is sufficient for a reliable basic electrical connection for bench testing. The pictured driver is a very small tweeter and is barely held in place with both wires inserted between the print and spade terminal.
I wanted something that would fit on the faceplate of the little hacked audio amp enclosure I have been designing. I think 6 of these will barely fit across the front and under the actual circuit board assembly.
This one might be worth the hassle of setting up an account and sharing on printables if it does not require the goggle server connection like it did in the past when I tried.
The thing is, I dial in my prints to 0.3mm clearances and this absolutely requires that clearance. I do not care to print other people's designs because most are really terrible for things like supports, designing for 3d printing, clearances, and general slop. I'll occasionally toss someone else's STEP or STL in FreeCAD and rebuild the thing but I usually just use some conceptual idea of anything I see elsewhere. I think with this one, I could share it as a negative Boolean STEP file to be most useful. Then it would only require others to import and do a boolean cut operation to use the design. Maybe I will do so if it works out well in my enclosure with 6 of these all resolving well and functional. What do you think, would you ever care to find and print something like this in one of your designs? Do you think anyone would even understand the value of printing such fundamental componentry instead of buying hardware and gluing it together with a 3d printed design? Like, this could easily be configured to use a loop of solid core copper wire as the connector terminal for a low voltage bench power supply that requires no other hardware.
Also, I had a rather irritating encounter with Dessalines (the Lemmy Dev) on ML a few days ago. I want to move off of Lemmy but I kinda like the rest of you, so maybe piefed is an option. I haven't looked into it deeply as I thought rust was worth supporting more, however empowering these guys as authoritarians is not on my list. I'm in a position to move this community if people want but like I always say, I'm just the janitor here. I do not matter. I would just as soon give this place to someone else if that is best for the community. I only want what is best for all, which is probably stability first and foremost, but if you feel otherwise, maybe mention it, maybe we'll make it happen.

Found out about this website from today's Geology Hub uploaded on YT

This crystal doubles images, meaning that if you look through it that anything on the other side whether that be text, a person, or a photo of a volcano will appear to be doubled. But, why does this unusual optical property occur when utilizing a crystal of calcite? The answer is a fascinating phenomenon known as birefringence, which this video will explain through the expertise and analysis of a geologist.
This is the about-page of which text continues past the posted image on the left side:

And as a further aside, the image was made with an F-Droid app that is new to me but popped up 3 months ago apparently and has a lot of great features for stitching images and creating content:

I made an audio thing
(lemmy.world)
0.25mm nozzle, clear PETG, Prusa, 6mm standard headphone jack, upcycled broken bluetooth headphones, three times larger battery, snap fit with no hardware, FreeCAD, 2nd print iteration, listening to it now, no tricks - it holds together firmly and is usable and actually sounds better than the original by a long shot from better headphone drivers I guess or proper soldering, oh and power button built into the flex of the design, OC only posted on Lemmy

What is this brand?
(lemmy.world)
The info wore off the grip and I do not recall what it was. I think it was a German brand. These have been one of my favorite tools for a decade. The jaws are much more narrow than what is typical for side cutters and these handle like a surgeon's scalpel. Best of all, they can be sharpened many many times. Unfortunately, these are getting close to end of life from all of my sharpening and pivot pin wear. I want to get another set, but I have never been able to figure out the brand to find them again. They were given to me by a tech for a computerized Guru bicycle fit machine we had installed in one of our bike shops in 2012.

...and thank you god for guiding mossad to replace the overt optics of Epstein with a more discrete version of the elite pedophilic prostitution network of semenitism that leveraged genocide in Palestine, bombing Iran, stealing citizenship, scapegoating immigrants, regressive social political and scientific progress, and funding authoritarianism
