### 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).

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.

### Comcast is the honey badger of ISPs – injects pop-ups into browsers, doesn't give a fsck

#### Re: More than a security problem

If it you downloaded that web helper tool, you deserved it for that...

(If they hijacked the router themselves when you never signed up to it, then you deserve it fro going with BT... unless they were the only choice. ;) )

### Emulating x86: Microsoft builds granny flat into Windows 10

#### Re: This is probably...

I kind of agree this is like building a car that also doubles as a bicycle...

... and a boat, and a plane and a pair of crocks.

### Customer data security is our highest priori- ha ha ha whatever, suckers

#### Re: CrazyOldCatMan

Yep, the look on the cats face says it all... the sofa pushed the cat off!

### Top of the bots: This AI isn't a cold, cruel killing machine – it's a pop music hit machine

#### Re: "Promoting the poorer ones"

Ah... appears that quote may be fake. Oh well, I still assume it's what goes through peoples heads.

#### 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.

### Race for wireless VR headset heats up

#### Re: Eye-tracking is the breakthrough we need

NVidia are working on a VR lightfield display. It seems really good. But requires the types of manufacturing and technology that are eye watering.

(Beer, because those kind of goggles are cheaper...)

#### 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.

### What went wrong at Tesco Bank?

#### Re: Santander must also not be hashing passwords

Why not just hash each character...

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).

### Bungling ATM thieves blow up bank statement machine

#### Re: Might be Dutch

A better idea if for the Bank manager just to funnel it into their Jag/Merc... why let the crims have the fun of an explosion, when we can have the fun of at least getting all that petrol off them!

Troll icon, because it is probably the right time to do it when done to the criminals.

### 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: Oh dear Apple

Will it not take 2 or 3 years to get the designs and hardware and manufacturing for a fingerprint scanner under the screen?

(Goes off to Google "under display finger print scanner" to see if Apple are designing it from scratch or just copying it from a competitor...)

#### 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.

### Siri, clone yourself and dive into this Samsung Galaxy S8 smartphone

#### 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.

### Tesco Bank limits online transactions after fraud hits thousands

#### Re: Tesco bank accounts...

You wouldn't find being a customer funny?

#### Re: Open source to blame?

Yes, because the design of roads being publicly open and free to everyone, means all the roads get used by criminals...

... now if only we had kept the design for roads and cars proprietary we would have stopped all bank and store robberies...

### CERN also has a particle decelerator – and it’s trying to break physics

#### Re: Next question...

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

So before you ask "which way does it fall?", first think "what is it's mass?", then come back and decide what question is best to ask. :)

### Dark matter? More like diet matter: Super-light axions may solve universe's mass riddle

#### 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: Dark, as in invisible

A million up votes for you. Why? Because when people call it "the dark side" when they mean the far side, and not the "side facing away from our sun", I have great regret they never tried to understand the world they live in.

PS, and don't even get into "does a photon have mass" discussion without first confirming we are not talking about (the now redundant?) term of "rest mass".

#### Re: Wot no Boffinry?

I suggest we setup a team of Boffins to find this elusive "researcher", possibly of greater mass than we previously detected...

### Windows 10 market share stalls after free upgrade offer ends

#### Re: Linux and Games...

If you're going to complain about Linux not playing recent games at least choose good ones.

(Ok, I'm asking for downvotes there. Most of those games are good, just feel a little let down how each generation cuts content without adding features except shinier graphics and more pew pew. Hopefully I'll get all my indie games working in Linux later today... just waiting for the net to get reconnected.)

### NASA's asteroid orbit calculator spots a hot rock zipping past

#### Re: Five days notice

Five days is enough to get people out of the area. Depends on how big and if they wish to.

Most natural disasters are political and social in the block to their solutions, not engineering or physical.

### 'Hacker' accused of idiotic plan to defraud bank out of \$1.5 million

#### Did he just...

change his name to J P Morgan, then ask for his account to have a transfer?

### Samsung are amateurs – NASA shows how you really do a battery fire

#### Wow. Make this a feature...

Not a bug.

If a rover/lander has more than one battery, use the spares as replacement landing rockets for when the landing rockets fail.

(Yes, I know 99% of the crashes are due to software/deployment/distance sensor failures, not the rockets... guess I'll get my coat)

### Divide the internet into compartments to save us from the IoT fail whale

#### It kind of makes sense.

With all these IOT devices being so dangerous, just don't let them on the internet... ;)

### Gravitational lensing event could provide ideal conditions for planet hunting

#### Re: That's one...

Yep. Seems the joke went over at least 2 peoples heads. It may be a few years before [some?] stars pass each other again. But other methods could confirm the results. Scientific data is even better when you have multiple methods of confirming the same things. In this case such as dimming, wobble and whatever else we can think of.

#### That's one...

big needle in a haystack attempt there. But with the right tools, it is doable. I'd not want to be the one holding the magnifying glass steady for that though. Oh, and how long a wait before they can confirm the observation with a second attempt, as it's not "science" unless they do. Right? Or will they wiggle out of that requirement? ;)

### Here's how much HP's 3-in-1 PC replacement will cost you

#### I have nothing to say.

I'm not the market for this device, service or it's price point.

But I do for some reason feel compelled to mention that. Perhaps because I understand how anyone would want such combinations...

### Microsoft keeps schtum as more battery woes hit Surface sufferers

#### Re: Spro4 not too bad

There are some manufactures that do full features and specced "netbooks" (See Razor for example). Thing is, they are very expensive.

### Apple's car is driving nowhere

#### I'm not sure if serious...

or joke.

It is [hopefully] autonomous.

### Apple’s macOS Sierra update really puts the fan into 'fanboi'

#### Re: Iseless Technology

It's fantastic for searching. But mainly when your not in the mood for typing. For example "Hello Google, play me some Jack Garrat" or "how do I get to such and such".

I can do this as quick as or quicker than typing, or while also doing other things (so great for music while doing little jobs).

However, as a *useful* everyday feature? Only really for those tasks, the rest is gimmicks.

### RBS debit card payments have gone utterly TITSUP

#### Re: Inevitable

Oh, seems I pushed out my post too early too. Must remember to proof read, "other banks", not "backs".

Oh well, the risks of IT...

#### 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. :(

### BT will HATE us for this one weird 5G trick

#### Re: Surely ...

Lots is going to cottage industry. But that is by the by. Supply and demand vary slightly back and forth, but the majority will stay centralised.

### Pound falling, Marmite off the shelves – what the UK needs right now is ... an AI ethics board

It's call "Law". Law is a written code of rules. We execute them (um, poor choice of words I know) by hand when applying law or taking things to court.

A computerised system increases fidelity, speed and amount of data.

Can those involved in promoting the idea prove such increases work out? That they don't hit a reduction in returns or just make the system so complex in implodes?

### Invasion of the virus-addled lightbulbs (and other banana stories)

#### Take an AI and replace it with a...

Car or a hammer. It does what it does. Leave any one unattended, and what happens?

Same for people. Leave them unattended, and surprise, they don't follow *your* requirements.

Providing technology, computers and programming (I'll not call it "AI") is kept under watch and maintenance then it will be fine.

I'll grab my coat, as it seems someone forgot to service the... oh.

### 'My REPLACEMENT Samsung Galaxy Note 7 blew up on plane'

#### Re: has there been any news on WHY they catch fire?

"Make room for a bigger battery".

It's empty space on the iPhone 7. Well, it's replaced with a barometer. Though I think the Note range has one... so perhaps possible to make space for the battery, but I doubt it.

#### Re: re: you've still got some time before it combusts

If my phone got "too hot" I might dump out the battery. However it's such a tiny risk, there is little possibility of it I guess.

Still. I prefer the life of device benefit from swappable batteries.

### TalkTalk gets record £400k slap-slap from Brit watchdog

Are you still a TalkTalk customer? Honest question. It intrigues me.

### Got a great IoT story to tell? You have until Friday to let us know

#### Re: Andy S

But those are things that need the internet. Less than "Internet of Things". Which is where the light-bulbs come in.

I guess that's what the phrase means to me. A device is either "using the internet to do a job for a customer" or an "IoT" which is just "the internet bolted onto something that did not need it".

Mines the one containing the catalogue of "Connected" washing machines we could not *give* away.

### Samsung: And for my next trick – exploding WASHING MACHINES

#### 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.

### One-way Martian ticket: Pick passengers for Musk's first Mars pioneer squad

#### No idea why...

you got a downvote. So have an upvote. Honestly, if this was done for say the moon first (just to prove the launch capability) then it would make a lot more sense.

Prove you can get a habitat of some form, and please have people at least partially within distance for a rescue (I'd assume you'd have more than one craft, as your running a business right? It won't make much on low volume, so the more the better in the long run, as with the Falcon9 and beyond etc).
