What is that way in your mind?

Here in NJ they separate neon from the air. This is not a problem.

If you are limited by the number of atoms then just add more atoms!

Usually other systematic errors are the problem though.

ERPNext is a really excellent but mysteriously unknown system for accounting, CRM, and project management.

Sense just guesses everything wrong. I can strongly recommend Emporia energy, which has per circuit monitors.

However! fusion plants are much larger than fission cores, and the neutrons are an order of magnitude more energetic, so you wind up with both way more mass and way higher activation.

For me, getting the keybindings right is the killer feature Elementary OS provides. Sadly it doesn't actually install on any of the old MacBooks I have, so I don't actually use it.

It cheerfully builds and runs on M1.

STM32H7 is the upgrade path, but it doesn't seem to be any more available.

Not more energy than they put in. Just like every other fusion experiment.

It's not just a slight concern.

- Fusion reactors are an order of magnitude physically larger than fission reactors,

- The particle energies are an order of magnitude higher than fission, resulting in much nastier activation

and that results in orders of magnitude more highly radioactive waste.

Subramanian and Kumar discover that COVID cases are not correlated with vaccination rate. But everyone knows that the vaccine doesn't stop you from getting infected; rather, it reduces hospitalization and case severity.

The problem with this paper is not the result, but the authors' tone punching through, which expresses surprise at this result. This paper should have been rejected for revision on that basis.

Anecdotally, I find that parts that used to be in stock are simply bought up en masse by speculators, and then are resold at a huge markup. So you will routinely find that all the authorized distributors are zeroed out and all the unauthorized distributors are selling for 2x-100x the price.

I'm not sure when this became a thing, but it's very real to me. It's a snowball effect; these folks get better and better at buying everything up, and then get all the capital to continue and expand the process. I have stock notifications everywhere and everything is gone as soon as it is posted.

Regarding the article - it is definitely not all about fancy fabs that can't be built - these are analog and power parts! And microcontroller fabs are fancier, but usually many many nodes behind state of the art. Maybe it is a capital thing, but every fab I've ever encountered is more than busy. Sure, you lose money trying to do the hardest thing and failing, but the problem is so widespread across so many non-edge products that it must be explained by other factors.

Here's a USB-powered unshielded MEG sensor that you can just carry out into the woods

So that's new.

I've noticed that the shortage of chips is also strongly driven by speculators simply buying up everything in sight and trying to resell at multiples of the cost.

While there are lots of similar efforts, the bidirectional interaction struck me as quit promising; you can apparently push/pull on features and have the Scheme code update.

There also seems to be an emphasis on correctness in the code, which sounds great to anyone who ever tried doing real work in FreeCad, though of course the gap in functionality is vast.

Adore Calca on macOS and windows.

It would be useful to show a list of the day's next events and to-do's. Is iCloud sync even possible?

Downloaded the demo app for macOS; feels like an alien UI even though effort was clearly made to use system widgets. On the positive side, the app is only 4 MB and consumes 50 MB at runtime, so at least they've succeeded in that important aspect.

In my view the positive direction over 20 years has been how chrome has been receding. With full screen and split screen apps, all you see are the apps. The OS lets you swipe between them. So it would appear to me that the focus should rather be on the app ecosystem and the slow, mild poisoning from electron/web apps.

For me the attraction is a reasonable screen and keyboard - that sort of interface is by far the most difficult part of hardware projects.

1. No, anyway, your phone would have to be engineered to be non-magnetic to the same level that you wish to make measurements. 2. Yes, faster is better. Flying lower is also more specific if you have a sufficiently good magnetic map.

Magnetic navigation is totally real and seems to work great.

Diamond magnetometers might not be a great fit for this application. They require a powerful laser, RF, and are presently huge and impractical. Also, they are just terrible at accuracy and drift like crazy. Finally - and this is the thing I really can't get - they require a giant magnetic field to operate. If your magnetometer has a giant magnet bolted to it, you would expect it to basically measure drift in that magnet. Diamond magnetometer people will jump out of the woodwork now, but I haven't seen published high quality data that says otherwise. Would love to be proved wrong.

Diamond magnetometers are great at being a magnetic microscope since they have really high density of measurement sites and you can stick it right up next to an object of interest.

The papers describe a new magnetic field sensor that can measure Brain signals. What's new is that you can do it without a million dollar shielded room. It's just powered by USB-C on a MacBook.

Calca is way more natural for me. We could use an open implementation.

I would say the key difference between DARPA funding and other research functing is that DARPA PMs have a crystal clear map of the leading edge in a field that's ready for advancement and can target it perfectly with both money and real competition.

Quickbooks for Mac uses sqlite for its file format and this allowed users to query the books with any SQL browser!

Alas, they encrypted the file starting two years ago.

The super thin USB-C 2.0 cables are just ideal for charging. The thicker ones with the USB 3+ signaling are great for high data rates. Just pick the one you need for the job.
