Oppo's New Phone Hits 538 PPI

maeka Re:aha! infinite repeating sound required for Nyqu (217 comments)

Now it suddenly makes sense to me, I "get it". Infinite samples of a repeating function will create a unique pattern.

You're getting closer.

You seem to be forgetting that the signal is bandpassed before encoding. Thus any frequency below the Nyquest limit maps to a unique pattern.

A sound recording of duration 1/R second will generate one sample. The value of that single sample tells us virtually nothing about the sound.

Obviously,
For that signal has a period twice the lowpass frequency.

Since real-life sounds are not infinitely long repetitions, samples of real sounds can be pretty good approximations, only.

But you know what? The ear can't distinguish those either. What does a sub-cycle-length 21 Khz tone sound like?

It doesn't sounds like a continuous 21 Khz tone.

Such signals, in the context of hearing exist only in theory.

How Do You Backup 20TB of Data?

maeka Re:reduce the amount (983 comments)

There is an increasingly large number of devices (just about every lower power device of the last 5-7 years) which will play h.264 and not divx. Since the era of the iPod 5th gen ("iPod Video") the trend has been for h.264 hardware decoders paired to relatively weak CPUs.

disingenuous sarcasm never got anyone anywhere, so good luck with that.

Google Earth's New Satellites

maeka Re:Resolution (118 comments)

Seems to me like the current pics have pixels thinner than 0.5 meters... I feel like I am missing something?

In many (most?) developed western areas the images are from planes, not satellites. There is a great deal of high-res aerial photography on the open market and Google has used much.

The development being discussed in the article will benefit outlying areas and places where having temporal density is useful.

Open Source Radeon Gallium3D OpenCL Stack Adds Bitcoin Mining

maeka Re:yawn (140 comments)

If you're so confident, why not short bitcoin?

For someone to short there has to not only be a robust market, but also a person (or people) taking equal and opposite long positions you can borrow from.

Do any of the trusted and established exchanges offer shorts?

Open Source Radeon Gallium3D OpenCL Stack Adds Bitcoin Mining

maeka Re:Will increased exposure make the market rationa (140 comments)

At that point, the people with the massive computing power are going to have incentive to throw at least some of these Bitcoins into the market just to generate more trade volume.

Bitcoin's exchange rate against the USD has no bearing on its utility as a token of exchange.

With fast enough exchanges and sufficient enough liquidity ("enough" being the key word) the total amount of Bitcoins in circulation doesn't even have a large impact on trade volume. Bitcoins don't get consumed in the process of trading.

Therefore I don't see how those with massive computing power (for generating income through transaction processing) benefit by selling previously-hoarded coins. If anything they benefit by not selling their coins, maintain artificial scarcity and thus high exchange prices since they get paid in coin.

maeka Re:Will increased exposure make the market rationa (140 comments)

What bubble? Plenty of people perform transactions using bitcoin to pay for goods and services every day and go away happy. How is that a bubble?

What bubble? Plenty of people performed transactions for houses in 2006 and went away happy. How was that a bubble?

What bubble? Plenty of people performed transactions of dot-com stocks up through early 2010 and went away happy. How was that a bubble?

Iranian Lab's Quadcopters To Rescue Swimmers

maeka Re:50mph? in your dreams. (81 comments)

He was responding to someone talking about the efficiency of non-pitch-shifting rotors. He commented on how efficiency doesn't improve much once you introduce blade pitch-control. He used fixed-wing aircraft as a contrast.

That's all.

You were the one who chose this subthread as your Nteenth location for saying the same thing, ignoring relevance to the specific discussion at hand.

Sure this overall story is about QCs and rescue. But the subthread you chose to lose your mind in isn't.

As I said. A nit which wasn't offered. GPP mentioned the efficiency but in no way suggested that made them unfit for the job at hand. The only person running with that claim is you.

Canon Shows the Most Sensitive Camera Sensor In the World

maeka Re:That "full moon" "after" shot... yeah... no. (218 comments)

Quite aside from that, I don't think we're anywhere near the point where we can detect every single incoming photon, so there's still room for improvement regardless.

We're a lot closer than most people think. A hell of a lot closer than we are with solar panels.

'Download This Gun' — 3-D Printed Gun Reliable Up To 600 Rounds

maeka Re:The way things have been going. (582 comments)

And when is the last time you've heard of that happening to a commercially produced firearm? The only failures I hear of are cases where the firearm jams or accidentally discharges. Having the entire firearm blow up in your hand or have projectiles coming out of places other than the barrel is not something that gets any attention. And the accidental discharges are pretty much always the result of somebody handling the firearm in a way that's not safe.

Which suggests that it likely doesn't happen or is so common that it's no longer noteworthy. I suspect that it's the former as I've never heard of it happening in real life.

If you're not familiar with the Beretta 92F's (aka M9) habit of throwing slides into shooter's faces you haven't been paying attention to guns for very long. This isn't some Saturday night special failing in a catastrophic manner, this was a premium-priced weapon chosen to replace the 1911 as the US Army standard sidearm.

Despite Beretta's continual claim that the failures were due to military use of +P rounds, many prominent LE armorers have reported failures with standard pressure loads.

As Music Streaming Grows, Royalties Slow To a Trickle

maeka Re:The radio plays it for free, go cry somewhere e (665 comments)

If you're a top act, like the ones signing that ad, your label really does take good care of you... It's the rest of the musicians, the majority, that get shafted by the RIAA business model.

If I'm hearing you right RIAA = Scientology?

In Brazil, Trees To Call For Help If Illegally Felled

maeka Re:And here is the solution (130 comments)

Setup EMP charge. Bulldozers wait outside 'blast range'. Clean area. Move bulldozers in. Profit.

This isn't an attempt to stop industrial-scale illegal logging. There are much easier ways to track and trace activity on that scale.

This is an attempt to stop "sustinance" logging. Literally poor individuals poaching timber.

North Korea Announces 3rd Nuclear Test, Anti-US Aims

maeka Re:A strange game.... (597 comments)

We can prevent NK from bombing Seoul or marching 35 miles, if we strike hard enough in the first strike. It would help if China was on board, but it's not necessary.

We possibly could but that's not the real threat to the South.

NK is believed to have at least thirteen thousand artillery tubes pointed at Seoul. Most of them are embedded. We don't have that many bunker-buster bombs in inventory. We can't deliver that many precision munitions in an hour even if we did, and we don't know where most of the tubes are. Even the most conservative estimates (such as the recent one by Roger Cavazos) put the death toll at 30,000 Seoul civilians where the high end one count in the millions. And that's just the first hours.
