Three certainties in life: Death, taxes and the speed of light – wait no, maybe not that last one

Re: Faster than light

You cannot rotate the torch faster than the speed of light. The emission of light is at the speed of light.

So you effectively have a spiral of photons/waves travelling away from you at the speed of light in a spiral (if you span 360 and not just across the wall).

The question is, do any of those photons/waves appear to be travelling faster than light from any perspective/trajectory? Einstein would say no and I assume it holds. I'm just not smart enough to do the maths just now though.

Re: c is calculable

I can think of at least one way the speed of light could have exceeded the expected speed within the early universe... if it was re-emitted but due to time length/iteration/quantum uncertainty limits did not interact as often with particles. It could have "skipped" particles, due to them being so close together? Then it would not be limited by re-emission as it is now in water/glass etc... due to the early universe being so dense.

Though it may just be me who is dense.

Re: "wouldn't the charges involved modify the trajectory"

There is a theoretical problem/puzzle on how much light you would need to optically lens light via it's own gravitational pull (from it's own energy).

I'd have to look it up again, I cannot remember if it was considered impossible, impractical or if it would happen. Does the early universe have that high a concentration of light/energy? I'd assume no due to expansion and it not becoming a singularity.

Re: peer-reviewable and repeatable experiment proposal

Good idea, but best to drop your bug testing loop into the time travelling loop.

For example, 1) Design and build a Time Machine.

2) Send time machine to the past at a chosen time, if it arrives with bugs, fix as many as you can and send it back further.

3) Once there are no bugs, send it back to the present (1 second in the future from the time machines new perspective).

4) Do your experiments.

This means you get a bug free time machine rather quickly. Now if teaching past yourselves how to bug fix the machines is an exponentially increasing problem (perhaps the laws of physics trying to keep hold of your device!) then just send it to the future for them to bug fix instead...

Microsoft’s ‘Home Hub’ probably isn’t even hardware at all

Re: MS Watch

The Play station "3" was out, thus "Xbox 2" would not have been a working marketing campaign. Nintendo dropped out (long ago?) from such a race, but we can assume keeping 3 and or higher in the name was to try and show consumers the level of the product.

"One" was to try and show how it was a reboot I guess, as trying to pull a 360 again and emulate the "Playstation 4" name would be too obvious a trick.

Re: "Promoting the poorer ones"

Interestingly a recent movie blog posted a probably true quote from top movie execs and the reason why most of the new content is "poor".

"‘We don’t care. We don’t really care. The amount of money we’re going to make globally, I mean 70 percent of our audience is not going to be seeing this in English. And it doesn’t really matter, these things that you’re bringing up about the flaws of the script."

That was about the latest Batman movie too! So budget and time is not a limiting factor, just the desire to make anything of quality, when it encroaches on the profit margins.

Re: Still "ten years away"?

Yes (I assume). Dreams can be very much visually led from recent visual memory (the film you watched, sitting at the desk all day, driving etc).

Lucid dreaming though might have more to do with how deep you are sleeping. So while VR might effect what type of dreams you have, if you wish to induce a "it's so real I'm there" via lucid dreaming... I'd not want to take the drugs that cause it.

Solution Q

Sounds like Vapourware, or for a better description, too good to be true.

If released it will probably be on par with mobile phone VR, not PC VR.

The refresh rate, FPS, image quality, head tracking etc are vastly higher quality on PC than a phone.

As an example, the PS4 head tracking VR, is currently inbetween the two techs, and uses a camera for tracking. Many report motion sickness from it, as the hardware is just not quite quick or powerful enough for it just yet.

The PC setups mainly need very highly powered systems, to do all the work quickly enough. Smaller devices start to lack this, and start to look like a bizarre slide show.

Re: Santander must also not be hashing passwords

But more seriously, I assume the "first third and fifth" version of pin checking if for *view* only options to statements and already assured bills and payments. When ever I need to add a new bill or account to pay into, or set a new DD, I need a new pin pad check (which is hashed etc AFAIK).

Why Apple's adaptive Touch Bar will flop

Re: I just found...

They saw a market no one else did. I'll give you that. Those types of GUI existed before, but not on touch.

There seems to have been an idea that touch screen was for business was for spreadsheets. Then apple made the touch device for consumers, and bam... the rest is history.

Re: It's not JUST the toolbar

How? I don't think that Apple do change connectors that often. It's just changing it so early and so completely with no intermediate device. If last years had 1 TB3/USB C and then they did this, people would understand. It's the "cut of your leg or nothing" attitude, the same as with the headphone connector, that is so jarring to consumers.

It worked for the Macbook Air (curring CD), because it's an Apple ecosystem, and people were practically onto streaming content for audio anyhow, and it was not selling its self as a dvd player. :P

Re: It's not JUST the toolbar

I was going to downvote you, because it's obvious in 3 years time when the TB3/USB type C devices are everywhere, this will be a nice laptop.

Then I remembered, it's still 3 years before that will be so. And will this hardware last that long? I probably will, but why spend the extra now, when you can wait it out, and get an even better one in 3 years time?

Such a intermediate cycle, needed an intermediate device, with both types of connector, then next years/or after going 100% Thunderbolt (with what, half an hours design work? ;) ), so have an upvote!

I just found...

Your picture of that first iPhone: http://www.gsmarena.com/sony_ericsson_p800-pictures-326.php

Apple were the first to market on one or two features. They got in the market at just the right time, when the size, power and accuracy of the parts all fitted into a phone. Software was one thing, but previously the hardware could barely cope with the most basic layouts. Once the processors caught up, then the world opened up to the idea of a smart phone.

But for those with the money, patience and big pockets, the smart phones existed before Apple, or even Google, came along to the party.

Re: All I want is a smartphone with long battery life that doesn't blow up. Is that too much to ask?

Sorry, your logic fails to meet an unpassable syntax. The only assumption or confirmation of anything I can make is that I exist. I am, and my sensory inputs give an indication that something else other than me may also exist. I can parse probabilities mathmatically and logically just fine. No contradictions there.

However, if you ask me how I know "anything", that is a longer answer.

They just confirmed that by the looks of it, so far, it has the same mass as expected.

Re: 1922 or 1977?

I assume, due to T invariance, "colour" is a better descriptor, as "time" is rather relative, so using the other description gives a fixed property to describe.

You would then describe it as "time" once talking about an entire system. But a single particle experiences no time (think of a photon travelling at the speed of light). However the interactions do... though I think every interaction effectively is a re-emission or interaction in the quantum field...

It gets rather complicated, but I'd go with their definitions for now. They have spent a long time getting it wrong (learning! :D ) to get to where we are now, and I'd not want to start getting it wrong too much by renaming again.

Re: Inevitable

I walked into the local Barclays (now closed :( ) a few years back. Noticed they had all new tiny little thin clients too small with hardly any cooling/vents (which I assume overheated as they were down for replacement/repair the next week) and commented on how they looked "new".

The cashier said "Yes, so new the software still shows dollar signs our side, but it puts a pound symbol down when we print your statement".

The fact it was outsourced software was not a problem, but that no time had been taken to actually change the GUI etc for their specific currency zone. So it makes you wonder where else they (and other backs, see headline above) cut corners/pushed out "upgrades" too early. :(

Re: Eeek!

"Top loading". The entire reason seems to stem from space. UK has smaller places to live in, so we go for front loading, with a cupboard/work surface above. You need extra space generally for a top loading.

Once something becomes common, then social pressure and idiocy kicks in and people refuse to change. If you asked for a top loading in a general UK store, you'd get looked at like you were weird. Though we do still have them in some places, and no doubt they are ok... but a lot of us have no experience with them, so they are also an unknown quantity.
