Uhhh is that not pretty much the definition of a "tech megacorp"?

Thats a good point. I think its probably because most of the corporations who fund and contribute to the kernel are American, and coordinating financial and physical contributions would be complicated across borders. Just a hypothesis though.

Jeeeeez that was a lot. I get the sense that the kernel has worked as well as it has because people saw it as separate from geopolitics and so didnt discuss them...now that politics has wedged its way in I feel like it may have opened that door permanently.

Yeah, 80-100 Wh with a Lunar Lake or any modern AMD CPU. 35 Wh with meteor lake of all things is a joke.

Yeah my org is about to ban using anything but the outlook client for email access for "security" reasons, and ban all other logins. We're on a Kubernetes cluster, so historically you've been able to login via Thunderbird or use the Gmail web interface as well.

If they go through with it I will riot.

Would I have to use flowers that are closer to cyan, magenta, and yellow so it is closer to the cmyk color model or does that not help?

The thing about that is the "k" in CMYK is black, because it's very hard to mix other colors to get anywhere close to black. I think you'd want to look for a pigment which is black and bleaches under UV, but that's going to be hard, since bleaching from black fully to white so other colors can be applied will be crazy hard. Might want to just compromise to brown being your "black point".

Do I need to do it in multiple layers?

Yes. Most of these pigments are only going to be sensitive to UV light, so each layer is going to be a monochrome representation of the total light exposed on that layer.

Also I was planning on trying to use the paper as a replacement for photo paper in pinhole photography with it instead of a mask.

That makes this almost impossible, frankly. The mask method means that you have direct sunlight hitting the paper at full intensity. For a pinhole camera, for one thing you're not pointing at the sun, so the light is maybe 5-10% as intense, but the pinhole aperture dictates the amount of light. Say the paper is A4 for math's sake, and so is 62,370 mm^{2. A typical pinhole camera's pinhole is probably a bit less than 1mm}2, but let's say it's 1.

The brightness of light on the pinhole is the same as it would be on a piece of paper held in the same place, but then once inside the camera the light spreads out to cover the whole paper. That means that relative to the mask method and leaving it in the sun, the pinhole method exposes the anthrotype to 0.05×1/6,2370 = 0.0000008 the light of the mask method. This is all too approximate to calculate what the exposure time might be, but it's unreasonably long, a couple hundred years.

I think the most practical method would be to take a digital photo, filter the colors into a monochrome for each dye you want to use, print that on a transparency, and use that as a mask.

Nope! Lithium polymer batteries are substantially different from lithium ion. Each generation of lithium batteries is a pretty unique chemistry, the only thing that stays constant is the use of lithium as the cathode. Electrolyte, anode, and interface chemistry actually progresses pretty quickly.

Also, for drastically different battery chemistries which have been commercialized, see sodium ion batteries, and to a lesser extent NaS/ZEBRA batteries.

**edit: typo

Can you imagine having a 31 Wh battery for a meteor lake part?

Also it may be light, but it isnt thin -- it says it has a whole RJ-45 port! But other than that the IO is unusably limited.

Um I think it's worth noting they had only been actually out for a month, and had unfinished firmware, etc.

Qualcomm basically said that if devs wanted to develop for their snapdragon laptops they should buy one of those, but six months after they came out is not a great time to make up your mind about that.

Hmmm interesting idea!

I think your biggest limitations are going to be contrast and exposure bleed. First of all, typically mixing dyes of different colors (especially plant pigments which are not likely to be super dense), you get brown rather than black. For contrast, I think you'd be limited again by the lack of color density in your pigments, but as long as you're OK with pastel colors, that could work.

For exposure, at least based on the Wikipedia page you linked, you're talking one layer taking a 2h exposure. Trying to do say three layers would then take six hours, so whatever you're using as a mask has to be super absorbent or reflective to UV (think very thick black paper or tinfoil). Anything else, and your underlying layers are going to bleach somewhat.

I actually use GIMP regularly these days, I found Scribus harder. Yes, Inkscape is more friendly. It doesnt follow the Adobe paradigm, but it's pretty quick to learn and is closer to the Adobe layout than other software.

The only thing that's kinda funky in Inkscape is cropping, which is done via "clipping", using another polygon to mask the component below. The selectable image stays the same size (but mostly invisible), making automatic alignment kinda annoying. However, thats for bitmap images, and Inkscape is meant to be vector-first, so that's not the end of the world.

Not familiar with HeliumOS specifically, but for a generic atomic distro I would try layering Python temporarily, and then getting rid of it when you're done.

Ive tried Scribus, and found the interface very hard to get used to. For folks coming from Adobe, I find Inkscape the easiest for design. I would use a separate program for cropping, I don't have a great recommendation for that.

In chemistry a lot of the foundational synthesis and work is as old as the 60s and 70s; people build on it, but in some cases those early papers said pretty much all there is to be said on a topic, so there's no reason to republish on it.

I've had to cite papers as old as the late 30s before, because no one has ever found anything to fix or correct about their work! Pretty impressive if you ask me, given how few tools they had.

Truly. Also the springer nature ones load so slowly for absolutely no reason, and break 10% of the time. I really don't get what their motivation is, do they think that after I've said no, I dont want a web version, I will be happy with a different web version?

Fusion used to work but autodesk changed the redirects in their login system, so it no longer does...

Tragic. Especially since there's no reason Fusion couldn't be a webapp or PWA, autodesk already made it annoyingly cloud-focused.

Can second this: direct heating of anything is always going to be more efficient. Also, only ~25% of incident energy on a PV cell is actually captured as electriciy (see here for theoretical backing), and the rest is lost in a lot of ways, but much of it is converted to heat at the PV cell, and if you're capturing that you're using direct heating anyhow.

Can confirm that the asusd and and asus-linux work fine on Bluefin and Ubuntu/mint; the Devs dont support X11 (which Mint is still on), but you can build it with the X11 flags on the GH repo and it works fine.

Is that true? I thought that pairs of USB-A ports shared the same PCIe lanes, and USB-C each got their own set?

Edit: thinking about it a bit more, I suppose it could depend on how the SOC/chipset allocates those lanes, but in my experience when writing a single USB I'm usually limited by the thermals of the USB, and writing well below the speed of the port. I suppose if you were writing many at once (or if your USBs were nice) that could bottleneck on the port speed.

Caaaaaalllllllzzzzooooonnnnneeeeeesssss!
