Technically, there is only one GPS, United States GPS (Global Positioning System).

However, there is more than one GNSS (global navigation satellite system). Several other countries have GNSS system, include Russia: GLONASS (Russian: Global Navigation Satellite System), China: BeiDou (Northern Dipper Star Navigation System), or European Union: Galileo. Additionally, there are augmentation systems that use GPS (or other GNSS) to increase accuracy in a given area. For example, US: WAAS (Wide Area Augmentation System), Japan: QZSS (Quasi-Zenith Satellite System), IRNSS (Indian Regional Navigation Satellite System). There are other regional, country and even commercial augmentation systems. Furthermore: Most GPS receivers are really GNSS receivers and can receive signal from one or more systems simultaneously. Random fact: More advanced receivers can be configured for select GNSS, augmentations system, or even miliary (or authorized user) bands for increase accuracy. Another random fact: Some receivers don’t work over a given speed to prevent their use in miliary applications.

I am thinking that some government entities over there easily has 499,999 bot/fake accounts that they can move around and subscribe to anyone they chose. I bet they even have a FEW to spare.

Technically, yes, light in a vacuum travels at c. An electronic in copper only travels at ~2/3c or about 200,000 m/s.

Quick Google search, I am wonder if it is this article: https://twitter.com/eevblog/st...

No, but they have the deepest pockets of anyone on the list...

Old news, the "Swedish House Mafia" has been doing it for years...

Nevermind, I RTFA. They don't mention EEG, but they do mention measuring brain activity.

EEG =/= EKG

A real conversation between two engineers about different methods that could or could not be used to fix a problem with a system.

Client Engineer: So let me get this right. I upgraded and lost functionality?
Support Engineer: (Ponders for a second.) Yep! Pretty much...

There is a fungus among us.

Raspberry Pi has a slightly higher production that than. They state a production of 0.5 million Pi per month. https://www.raspberrypi.com/ne... When you order $5 million+ per month in processors, you are ordering more than a month in advance. At that scale, they are ordering several million at a time and staggering the delivery.

Yes, it is less than the big boys, but it's not small by most measures. I suspect it has to do with their use of a older 40mn processor (they even state the 28mn are "easier" to obtain, but they are still supply constrained. My understanding it that its even a custom chip by Broadcom for Raspberry. Too bad that they can't use some of Nvidia's excess capacity on the smaller process node. But, it appears than Broadcom only uses down to 28nm.

Amazon: We want to keep of our own analytics to ourselves. Aka, if someone is going to be making money off of the analytics, we want it to be us...

I do think it is really shady to disable installed components because you did not buy the "license." I agree, if I own the component, I should be able to use it. I think that software upgrades to add new features, say a new Bluetooth feature and/or self driving (where there is some amount of R&D), is ok. But, enabling a software button to allow seat heaters is F-ing ridiculous. And, I could see a place where the self driving is disabled but the same hardware is required by the collision avoidance system (a safe feature that is mandatory and does not require a license).

Additionally, some type of "right of first sale" needs to be added. If the "license" is purchased, it is part of the car. Therefore, the owner can choose to sale the vehicle with or without the option (I think the existing owner should be able to transfer it to another model BMW), and the vehicle manufacture should have no say or control in that transaction (nor receive any additional money). And, if the vehicle manufactures does not like that approach, oh well...

Agreed, the calculation only results in 2000lb to 300lb of force to keep it moving with the rolling resistance of 0.002 to 0.0003 (depending on the steel rails). Additionally, they don't tell you the time it takes. The video makes it appear that it take around 30-35 seconds. To get to a top speed of 4.5mph over a distance of 1000ft, assuming constant acceleration is about 5 minutes (0.0222ft/s2), which requires about 6800lbf).

That is really misleading. And that does not include the towing capacity (of a truck on the road) vs. pulling a heavy weight through a rail yard.
