I've heard that, with AR, Microsoft HoloLens is very useful when you can bring in the blueprints for the house you're standing in.

You get a sort of super x-ray vision of what should be where in the walls.

I'm a little dissappointed that stories like this are upvoted so much in /c/Technology

I want tech news, not news about companies that happen to have a website and sell furniture...

So glad that we have GrayJay now.

Upvoted at first, but why is this showing up in the /c/Technology community?

I come here for tech related news, but this bot seems to be reposting a large number of items that are borderline tech related... and in this case it's a big stretch for this post to be tech related at all.

More paperwork to make cops jobs even harder. Will not help with public safety at all.

Sure, and by that logic, we may as well remove other restrictions. Why have warrants? It just makes their job harder and doesn't help with public safety at all. /s

The whole point of this is that cops have been given a lot of power. We need to have restrictions in place to protect civilians from power tripping cops as well. This doesn't restrict them from saying hello, but it does hold them accountable for escalating any minor encounter into an investigation.

I know you're joking, but I feel like answering anyway.

I'm sure you could get it to do that if you forced that through engineering, but it wouldn't be anywhere near as efficient as just using a CPU.

CPUs need to be able to handle a large number of instructions quickly one after the next, and they have to do it reliably. Think of a CPU as an assembly line, there are multiple stages for each instruction, but they are setup so that work is already happening for the next instruction at each step (or clock cycle). However, if there's a problem with one of the stages (or a collision) then you have to flush out the entire assembly line and start over on all of the work among all of the stages. This wouldn't be noticeable at all to the user since the speed of each step/clock cycle is the speed of the CPU in GHz, and there are only a few stages.

Just like how GPUs are excellent at specific use cases, quantum processing will be great at solving complex problems very quickly. But, compared to a CPU handling the mundane every day instructions, it would not handle this task well. It would be like having a worker on the assembly line that could do everything super quickly... but you would have to take a lot more time to verify that the worker did everything right, and there would be a lot of times that things were done wrong.

So, yeah, you could theoretically use quantum processing for running vim... but it's a bad idea.

Quantum computing wouldn't make these transistors obsolete.

Quantum computing is only really good at very specific types of calculations. You wouldn't want it being used for the same type of job that the CPU handles.

Here's a good list... a decent portion of those are every day items that we've gotten used to or just take for granted: https://www.jpl.nasa.gov/infographics/20-inventions-we-wouldnt-have-without-space-travel

Weather satallites GPS A bunch of different medical treatments/tech were developed on top of groundwork layed out by NASA: https://science.howstuffworks.com/innovation/nasa-inventions/nasa-breakthroughs-in-medicine.htm MRIs, artificial heart pumps, and more.

A bunch of different alloys that have since been used in a large number of industries for various purposes: https://ntrs.nasa.gov/citations/20100021913 Titanium alloys were lighter and more durable and made them ideal for use as bicycle frames or even in some medical applications.

Here's a link to a tech brief from NASA in 1969 where they discuss the potential for some of their invented alloys to be used in medical applications for implants and prosthetics: https://ntrs.nasa.gov/api/citations/19690000087/downloads/19690000087.pdf

And here's a link showing what kind of materials are used in biomedical applications today: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8546395/

Looks like the jokes sailed over your head on this one. /c/woosh

What are some of the scary scenarios you have seen? I wouldn't mind reading up on some good sources that would be useful to keep an eye on.

Besides what we see in movies (unrealistic world ending scenarios), what I listed out seems to capture the realistic worst case scenarios that I have come across.

I haven't seen any projections that say that the atmosphere itself will become unbreathable (although we could see a lot more massive dust storms that would force people to remain inside or only go out with proper protection).

They definitely weren't the first for touch screens, but I definitely agree that they pushed the smartphone industry to put a lot more work into it.

Prior touchscreens were laggy and unpleasant. Apple just gave us a really smooth touch screen (It was good for it's time) experience compared to what was out there and that forced other smartphone makers to get with the program.

Nah, Samsung had wireless charging in 2015 with the Galaxy S6, Apple started wireless charging with the iPhone 8 in 2017.

And wireless charging has been around long before that. Even those rechargeable toothbrushes have used it long before smartphones were a thing.

And Microsoft released the Surface Pro with a stylus before any iPad had them and I'm sure you could go much further back for other devices that had them before that.

Unless the baby is sleeping and you don't want to wake them.

I think we need to be realistic about what will actually happen. Climate change on the scale we're seeing isn't going to make the planet inhabitable.

What will happen is that it will be a more hostile environment to live in. Climate change is resulting in larger droughts/famines in areas that aren't used to it, as well as increased storms/flooding in other areas. Forest fires will get worse. Storms will get worse, species will die off, and if we don't have enough food to feed large cities, many will die and governments will collapse.

It won't be the end of the world, but the world will not be the same because of it.

The lack of people understanding this is what leads to poorly written laws.

They think that all we need is an income tax to tax the rich more.

So when laws are passed saying that they'll tax anyone making more than $1mil, people don't realize that it doesn't really do a whole lot.

It's important to note that most of what they "made" is actually just the stock that they already own or the stock options they received.

In general the actual cash that they receive is less than $500k.

Taxes are calculated differently on stock sales vs wages.

Ah, yeah, looks like they got it working but only for some accounts:

And...we might have spoken a bit too soon. It's not working for all accounts yet. More work to do, we're going to sleep now but back at it tomorrow.

They did eventually _{fix it though}. (Only about 6 hours ago).

Check your app store for an update to the app.

Edit: it's only partially fixed as of right now.

I mean, the proof of concept is open source, so anyone can go out and make their own iMessaging service now.

I'm okay with paying for this because they need to run a service for notifications and they also have to play this cat and mouse game with Apple.

The fact that Beeper has already come up with a patch to workaround Apple's block show's that they're going to work hard to keep this service running.

Edit: Beeper mini is still down, but Beeper Cloud is back up.

This is a lesson that we already learned a while back.

We used to make cars that were tough, but then we noticed that people were dying way too easily when they hit a tree or a wall.

In an indestructible car, all of the forces of a crash are directly applied to the people inside of a car. You might as well have have been riding a motorcyle when you crashed. They would need some advanced harness system that gives a little on impact without letting you hit the steering wheel or center console... there's not a whole lot of space for that.

In the cars of today, the car is meant to crumple in a way that absorbs as much of an impact as possible while trying to keep the occupants alive.

If the cybertruck is too stiff, even a collision at a slow speed will kill or severely injure the occupants.
