yes, i would define them very much as experimental
If you need high throughput, they and other vendors sell that.
There are tons of 10gbps PoE switches on the market.
If you're curious about what unix is and what a bsd is, I would recommend netbsd or openbsd in a vm.
Then say it. :)
All of those robots leave enough threshold to avoid collisions with other robots should they need to stop suddenly. The robots do on device calculations and report back their status to the central server to help other robots route around "damage" (stopped robots, for example). Instead, they give the robots general path instructions with enough buffer area to allow the robots to not trigger their own on device collision sensing. In the links that you gave, it's very clear that the robots do not depend on communicating with a central server if a worker steps in front of a robot.
By the way, in warehouses without such advanced protection, humans are _absolutely_ banned from the floor and it's treated like any other large industrial scale operation, including fail safes on gates (if gate is open, do not allow restart and human presence sensing (often through a badge of some sort).
Failure of this sort would lead to massive liabilities to the warehouse and robot owners. They are heavily incentivized to do things the right way. I'm not saying it's perfect, but it's actually quite advanced and safe.
And it has been that way for years.
As an ex-vegetarian (who rarely eats meat now), I'd love to see more research into this and what's missing. Also, what needs to be done to supplement a vegan/vegetarian diet for exercise is pretty well known.
But this "study" of a small sample size confirms what has been pretty much completely and unambiguously known for decades. And it's meat industry funded. Nice.
Yes, but that is only one component of a modern phone. Basebands and system bootloaders, among other firmwares, don't receive updates. Those are regularly attacked.
It's good that they do but it's not enough.
Tell ya what, you give me enough money for me to pay taxes like Zuckerberg, and I will /happily/ give you back half of whatever is leftover.

But, this is a slick looking web page with a slick looking app and a bunch of appeals to authority and even an "endorsement" from the EU (whatever that means).
Do not use this app.
> weird slow proprietary
They're often not weird, a simple single task runner with a few libraries to handle common tasks and cryptographic operations. Very simple, lightweight, and they generally share a common high level architecture (there's not much variation in an RTOS)
They're often not slow, they're minimalist OSes - barely qualifying as an OS if at all - designed to run a single task, with time guarantees, and to get out of the way. In fact, if it's a single task you need to run, they're faster than any general purpose OS - by design!
They're often not proprietary - a handful of RTOS with huge market penetration used in billions of devices (and now ThreadX) - are open source and have permissive licenses. What IS often proprietary about them are BSPs, but that's a whole separate issue. Yes, there are a lot of proprietary ones out there, but as a blanket statement, it's simply not true.
> readers run antiquated Android
Many use a stripped down version of AOSP, which has become a de facto standard BSP, yes. But many, many others do not (usually a flavor of embedded linux, or an RTOS).
> about some HP printer running buggy custom OS
It was a Xerox printer, and it was because he was frustrated from adding existing job management and notification features he had written to the new printer.
> Passage of the initiative presaged a "taxpayer revolt" throughout the country that is sometimes thought to have contributed to the election of Ronald Reagan to the presidency during 1980.
Yes. It would. And we need to build them.
Because Apple knows how to play hardball.
> Why choose Google if they don't benefit from it?
They benefit about $20B a year.
no, you wouldn't.
I never got this concern. Gas pumps are powered by electricity, and you're not going to hand fill a fleet's tanks.
Putting ten gallons of highly toxic and flammable fuel into a car-shaped object just to commute one person a few dozen miles is quite literally insane from all practical points of view. Electric tech is marginally less crazy, and also a step forward.
The second you want any educational specific SKUs, though, holy shit.
