Yes it’s placed flat, I’m not sure if it’s supposed to turn off but it certainly doesn’t.

I do love my bangle.js 2. i was feeling some nostalgia for my Pebble Time 2, so I pulled it out to try it with the new app, but then I remembered that I hadn’t updated anything on my Bangle in ages (dont generally have chrome enabled ony phone) and the updates made everything so much smoother. No reason to switch back to pebble, especially in its current state.

My only complaint is that there is no way for the watch to tell if it’s on your wrist, and the heart rate monitor and screen can’t be woken up separately. So it can be annoying at night, when unless it’s fully shut off the HRM and screen will light up the room every 10min.

Absolutely! I’m certainly not going to insist that things should only be published on RSS feeds! Anything is better than the authoritative source for evacuation warnings being a Twitter account. Every platform has its place, I’m just a big fan of always starting with an RSS feed for announcements as the “root source”, then pushing changes to the feed to all other platforms.

Not really. RSS feeds are better for announcements in my opinion, as there’s no account associated, and the ways of viewing them are even more flexible and simple than the Fedi infrastructure.

Same for me…wierd.

My god the headline of the Fudzilla article is misleading.

Yes, they froze the samples of polymer, but the actual change to the technique is to increase the post-emulsion bake!

Well, first of all China does make lithography equipment (for instance, Shanghai Micro Electronics Equipment, who are currently at 28 nm). There are a couple of others iirc, and they typically got started by licensing lithography technology from Japanese companies and then building on it.

The issue is mostly one of economics – fabs want higher-resolution lithography as soon as possible, and they only buy it once, which means that the first company to develop new litho technologies takes the lions share of the revenue. If you’re second to the technology, or are more than half a dozen nodes behind like SMEE is, theres not a lot of demand because there are fabs full of litho machines from when that node was new, and theres not as much demand for them anymore.

The issue with a new company making leading edge nodes is the incredible R&D and development cost involved. Nikon, Canon, and ASML shared the market when they all started developing EUV tech, and it took ASML 15+ years to develop it! Canon and Nikon teamed up, spent tens of billions of dollars on R&D, and dropped out once they realized they couldn’t beat ASML to market because there wouldn’t be enough market left for them to make their money back.

If you are truly starting from scratch, shooting for Raspberry Pi performance isn’t starting small, thats a huge goal. It’s a complex chip built on a fairly modern process node (28 nm for the 4B) using the second-best-established architecture.

The reasonable goal to shoot for would be an 8086-like chip, then perhaps something like a K3-II or early Pentium, then slowly work your way up from there.

There are a couple of further questions to be able to answer this best. First, when you say using only tech that is in the open, nothing proprietary, how strictly do you mean that? Historically, what Chinese foundries have done is buy a fab line far enough from the leading edge to not be questioned, then use that as a starting point for working towards smaller nodes. If thats allowed, it would be fairly trivial, 40 nm doesnt perform that badly.

If you want the equivalent of “open-source” fab equipment, as far as I know that has never existed. In better news, if you go back to DUV/immersion lithography, its not just ASML manufacturing lithography, Nikon and Canon were still in the game, so power was less centralized.

Second, what is the actual goal? If it’s just compute, no big deal. As long as you can write a C compiler for your architecture (or use RISC-V as other folks have mentioned) getting the Linux kernel running shouldn’t be too hard. However, you’re going to have to deal with manually modifying the firmware of any peripherals you want to run – PCIe devices, USB, I2C, etc. Not a firmware engineer, so I have no idea how hard it would be, but this is one of the things that’s been holding back Linux on Arm over the years.

All in all, depending on how strict you want to be, it could be anywhere between slightly difficult and effectively impossible.

Okular is the way to go for anything that’s typed, it has a lot more capabilities than Evince. For handwriting, I’ve used Inkscape, and Libreoffice Draw. They’re roughly similar in capabilities.

Depends on how much power is being transmitted to each base station, but it would have to be a colossal satellite to be “we’re all going to die”.

I pointed that out mostly as a limitation on how much power could be transmitted to each base station.

Microwave scattering is an absolute nightmare over that kind of distance. Even for much shorter distances, microwaves are only practical to transport over a couple of meters in a waveguide.

If its transmitting to a base station, we can assume it’s in geosynchronous orbit, or about 22,000 miles from the surface. With a fairly large dish on the satellite, you could probably keep the beam fairly tight until it hit the atmosphere, but that last ~100 miles of air would scatter it like no tomorrow. Clouds and humidity are also a huge problem – water is an exceptionally good absorber in most of the MW band.

I saw numbers reported for the transmission efficiency somewhere (will update this if I can find it again), and they were sub-30%. The other 70% is either boiling clouds on its way down, or missing the reviever on the ground and gently cooking the surrounding area.

Oh damn! Hey, if I was convinced that was a DSLR, then no need to rush getting a camera 😂

You seem like a really fun gi! Nice depth of focus & clarity, what’s your setup?

Sure, but they can’t build Pandoc translation against an experimental format, so no LaTeX anytime soon.

Well, Typst is explicitly a no-go for anyone who has to submit a manuscript, until it they get a damn HTML representation, so Pandoc can get it to LaTeX. There’s practically nowhere I could use Typst except my own notes, and I’ve tried!

Well, I doubt they’ll release one for my clippers since they’re discontinued, so that inspired me to go ahead and model a variable-depth one for myself. Based on some of the comments here, I thickened the comb blades to make them print more easily.

They havent released one for the razor I have, but honestly I might try modeling them myself. Doesn’t seem impossible, and I’ve been waning a deeper comb than they sell.

Yup. Even for technical writing, markdown with embedded LaTeX is great in most cases, thanks largely to Pandoc and its ability to convert the markdown into pure LaTeX. There are even manuscript-focused Markdown editors, like Zettlr.

There are currently 252 Catholic cardinals, but only 135 are eligible to cast ballots as those over the age of 80 can take part in debate but cannot vote.

You’re telling me the Catholic church has more term limits than the US Supreme Court?
