Is $899 for the M1 Air overpriced?

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 r

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 wit

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 unauthori

Here's a USB-powered unshielded MEG sensor that you can just carry out into the woods https://arxiv.org/abs/2001.03534 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

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 import

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 rath

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 acc

Preprint: https://arxiv.org/abs/2001.03534 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 po

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 rea
