Newer standards are lower power than 2G, and for more bulk data the quicker it is sent the less time the radio needs to be active.
The solution to spectrum saturation is to retire old standards like 2G, and reuse that spectrum.

We haven't even deployed the highest speed LTE variations yet, let alone deployed them widely. If some operators don't believe they can make money from and don't want to invest in 5G (or they hope refusing to give it to us like a little kid holding his breath will make us give in on net neutrality) that's fine.
Some operators will invest, or new ones will appear who do so, and to the extent that people really need that kind of speed for mobile data (something I'm skeptical of) 5G will be available, and those who decided against investing will lose out in the marketplace.
I suspect 5G will be mostly about provided fixed wireless broadband, and less so about mobile devices. Given that we can already exceed 100 Mbps on LTE and we haven't even exhausted what it can do yet, I fail to see the point of 5G for mobile devices. Where does a need for 100 Mbps data ever come in, aside from short bursts to sync with a cloud or download that giant powerpoint attachment a second or two more quickly? HD video only requires 3-5 Mbps, and while 4K may come to the big screen there is ZERO point to having it on a 5" display even if that 5" display is 4K. Even if you did that's far short of 100 Mbps, and unlike with a home broadband connection where multiple people might be watching different things at once you only watch one thing at a time on your phone. We certainly don't need the multi gigabit data rates 5G proponents are talking about on a phone. Any phone.
We'd be better off improving the usage of the spectrum we have today by phasing out 2G and repurposing those frequencies, and using beamforming and MIMO to improve the directionality and enable more overlapping use per tower. The idea that 15, 30 or even 60 GHz spectrum will be useful for mobile devices is silly - heck 60 GHz has trouble getting very far in fog, let alone rain, let alone through any outside wall of a building. 15 GHz should be OK in the rain at typical distances from the tower but still is blocked by buildings and trees. It'll be great in Kansas, not so much in NYC unless there's a transmitter on top of every traffic light (and even then would only work outside) That's why it really only has a future for fixed wireless, despite the hype.
You miss the point. They want to retire 2G in order to reuse that spectrum in urban areas, in order to do that they need to retire 2G everywhere, which means they must upgrade rural towers. They'll upgrade to LTE because that's cheap and widespread now, and because it gives them the opportunity for a second revenue stream from fixed wireless.
The main limiting factor is running fiber to towers that have only a T1 backhaul. That was fine for 2G, but obviously not enough for LTE. I wouldn't be surprised if in VERY rural areas, like places with population densities of only a couple people per square mile, if you see "LTE" on your phone but have terrible throughput. It'll be a tower with LTE that still has the T1 backhaul, because it was deemed too expensive to run fiber to that particular tower and the population density was so low fixed wireless wouldn't bring in enough reveue to pay for the backhaul upgrade.
The cellular carriers will be installing LTE fixed wireless broadband in a lot of rural areas over the next five years. With no competition from cable/DSL internet they have a ready made customer base, and spectrum in rural areas is cheap and underutilized. It will also help fund upgrading those rural towers so they can phase out 2G technologies and recover the spectrum it uses to deploy more LTE in urban areas where spectrum is scarce.
Nexus devices receive OS updates regularly, and Samsung at least delivers updates for their stuff for 12-24 months before they get bored of it. How many OS updates do HTC and Sony deliver? How about Xiaomi?
There are hundreds if not thousands of different hardware models in the Android world, and many are delivered with different point versions of Android with different UI skins layered on top. Many never have a single update, or only get updates from what they shipped with to fix obvious glitches but once it is "good enough" they stop.
Salesforce can't possibly test all the possible variations, so they're choosing a small subset of models that are at the top of the charts in sales. It isn't like they're choosing some obscure models that only sold 180,000 units worldwide.
This is Android fragmentation coming home to roost.
Since they aren't human readable, you don't know what site you are visiting until you are already there. It might be a site that is made to look identical to the one you want to visit, but isn't.
There are plenty of available attacks against Android phones that can p0wn them if you can just get the owner to visit a particular website. Even in the latest version of Android, but of course few people have the latest version, especially in China. Getting them to visit your malware infested website is really hard to do if they have to type in the URL, but is simple if you can get them scan your QR code! Who would notice if the QR code part of an ad in a public place with a lot of people like a subway or airport was simply papered over with the rest of the ad left as is?
This is a great exploit waiting to happen in China. We in the west will be mostly immune only because we didn't really adopt QR codes. And that's a good thing.
Then he was using his laptop while driving, and proudly admitting it in his article. I can't find it now, because googling "tesla autopilot laptop" gives me a million hits about the guy in Florida who died (since a laptop was found in the wreckage)
Add technology that forces people to pay attention so they can't use their laptops like the idiot reporter did who wrote a story about his use of Tesla's autopilot, or the idiot driver who was apparently watching Harry Potter.
Simply have sensors in the steering wheel that require a hand remain on it, and every minute or so have a light flash on the windshield via HUD that requires some sort of acknowledgment from the driver, like squeezing the wheel or whatever within a second or two. Failure to do these things will result in autopilot warning you that it is disengaging and you will be forced drive it yourself. Then you have no opportunity to drive "hands free" and have to keep your eyes on what is in front of you, rather than on a phone, laptop, DVD player or whatever.
Is it feasible to ever run fiber up to the remote northern villages - the places that are only accessible via ice roads during the winter? They aren't on electrical grids for the same reason - you can't put up poles or towers in the stuff.
I guess they managed to run pipelines, so it is possible, but probably only because of the billions of dollars traveling over those pipelines each year.
The head of the Android project admitted they basically had to start over once they saw the iPhone. It was first shown off in early 2007 and the first Android phone came out in late 2008. That's how long it took them to rework their 'smartphone with a keyboard like Blackberry' to be a 'smartphone with a touchscreen like iPhone'.
The idea that a 'rectangle with rounded corners' can be copied is of course ludicrous, what were they going to do make it oval (I shouldn't laugh, there were some phones sold in the mid-late 2000s that were oval just to distinguish themselves from the crowd) My beef is with the idea that if you beat someone to market by a few months that the follower copied you. You can't change the camera you're going to use in three months. In a year, sure you probably can do that.
Given the rumor mill industry and speculation surrounding future iPhones, and how big they are in terms of sales versus any one model of Android phone, if there were rumors that "iPhone 8 is going to include a FLIR sensor and laser distance measurement functionality" and an Android phone was introduced in summer 2018 with those features I'd argue they might have copied Apple even though they were first to market, because they may have added those features only because Apple was going to (assuming the rumors came true, of course)
BTW, there are no such rumors and while they would be cool to have those would obviously be niche functionality that wouldn't be worth adding to an mass market phone that sells 200 million units a year, but I could see those being worthy additions to a niche market Android phone - some extra durable model intended for contractors, home inspectors, realtors etc... That's the other thing about adding features - the Android phone market as a whole will always have more features than Apple because every phone sells in much smaller numbers than iPhone, and most sell in FAR smaller numbers. If it isn't something with mass appeal there's not a good reason to add it to iPhone, but adding a niche feature like turning your phone into a projector or adding a huge DSLR sized sensor makes sense for a few models of Android phones as those who need/want such features can seek them out without making the 98% of customers who don't want them bear the cost.
There have been rumors about Apple switching to dual cameras for at least some models of the iPhone 7 since right after the 6S came out - before the LG did. So it wouldn't copying them, unless you think whoever comes out later is automatically copying even when the product would have obviously been in the design stage before the competition introduced theirs.
As for a type C USB port, Apple is highly unlikely to switch away from Lightning at this time, though they may at some point. If/when they do, the idea that introducing a standard is "copying" is ludicrous. I guess Apple was copying Android phones when they introduced their first model that had LTE support, since Android phones had it first? If we use your moronic definition of copying, I guess Android phones copied Apple when they introduced a 64 bit CPU...
There's nothing stopping the UK from passing a law banning vaping in pubs while still permitting the higher strength that helps smokers bridge from smoking to vaping on the way to hopefully quitting. Having to go outside to vape wouldn't make it any more difficult to use vaping to quit, given that they're already used to going outside to smoke.
While I doubt there's much risk for "second hand vape", I think all tobacco products should be banned in public places for consistency's sake if nothing else. My pet peeve is people chewing tobacco in bars (probably seen more in the US than the UK) because of the disgusting spit cups that always accompany them, and their tendency of users to spit the pouches into urinals when they know damn well they won't flush (and shouldn't be flushed in toilets either) My state talking about banned all tobacco products in restaurants etc. to extend the smoking ban passed almost 10 years ago, but it failed to pass. I imagine it will pass in the next year or two.
From what I can see he's spot on as far as the Sanders wing of the democrats in the US. They think he's correct on everything and if you disagree you're told in no uncertain terms how wrong you are for doubting him. To me at least that's new to the democrats in the US, who were previously a lot more inclusive, realizing they needed moderates to be able to win elections.
This reminds me of how republicans have been in the US for a long time, where if you disagreed on any of their length list of "no compromise" social or economic issues you are a liberal (if they're being nice) or "libtard". With Trump straying from these views here and there (depending on the day of the week) a lot of them seem confused and retreat from the "all of nothing" viewpoint. The ones with strong religious convictions still back those, the ones with strong economic convictions still back those, but I sense the religious ones are relieved to be free of defending the economic convictions and the economic ones free of defending the social issues!
So from where I sit (as one who does not identify with either the republicans/conservatives or democrats/liberals, but with the libertarian party - though not their ridiculous extremist ideas like privatizing roads) the democrats look to risk hardening their viewpoint to the uncompromising stance the republicans have had the past 20 years, just at the time the republicans are softening theirs. Perhaps this was bound to happen, as demographics have been helping the democrats and hurting the republicans, so the time is ripe for the republicans to open up the tent while the democrats - probably feeling that with Trump as the nominee they have the republicans by the throat - seem to be operating under the belief that they will win this and future elections by landslides and thus can afford to cast out the nonbelievers who stand in the way of Sanders progressivism.
Since the pins on a microSD slot are only on one side, it would seem that they could arrange things so if the card is facing one way it makes microSD connections and the other way (i.e. upside down) it makes UFS connections. Or maybe it inserts sideways so facing right is microSD, left is UFS.
I'm sure there will be a way to support both, though I'll bet some phones will simply drop microSD support in favor of UFS support as supporting both will increase cost (probably patent licensing moreso than hardware) Hardly anyone is using microSD as a transfer format to get data to/from their phone. They're using it to expand capacity. For that you don't care that your old microSD cards won't work in your new phone, when you get the new phone you'll buy a new UFS card.
Looks like Android phones are finally going to be getting decent storage in those add on cards, instead of taking a major performance hit for stuff that is kept on the SD card.
So they're writing data via DNA using a heavily error corrected format. If preserved for a million years it would be readable, but unless someone knew the error correction format what you read would be gibberish.
Sort of like our so-called "junk DNA" - that almost certainly isn't "junk", but that fact likely won't stop alien conspiracy theorists from before long claiming our very DNA contains instructions to build a FTL communication device to call home to our "parents"...
To the extent that it saves power, sure. But most people don't turn their computers (PCs, laptops, phones) "off" very often anyway and unplanned power loss is really only a problem for PCs without battery backup, and even then only for poorly written apps that don't write their state to stable storage often enough.
If it is faster it might see use in servers and a few gamers who like to tune their systems to an inch of its life, but it won't see the mass market if it costs even if it is twice as fast if it costs 20% more.
If it is lower power it might see use in premium phones, and servers, but in standard laptops DRAM power is a rounding error and in PCs connected to the wall it is irrelevant in the cutthroat zero margin PC market.
Not to mention that if the guy brought body armor they couldn't know whether he may have also brought a gas mask. I'd prefer they took him alive if possible but only if they could be sure it would work. While some are complaining about the lack of a fair trial here, I don't think anyone is going to argue that he wasn't guilty, and Texas has the death penalty - which any judge in the state would surely give him for killing five cops. The only difference taking him alive would have made would be to learn more about his motives and waste a few million in a trial and years of appeals.
She certainly didn't do anything to prevent his suicide, like calling the police or someone else to try and stop it. It is really no different than if he was injured on the street and she stepped over him on her way to work without trying to get help.
I don't know the law in that state, but there's some sort of good Samaritan law there she's guilty of violating that at the very least.
Not sure what the value of "easy to remember" is in DNS servers anyway. It isn't like you need to configure devices to point at them very often, so taking a minute to look up one that isn't logging all your requests to add to their data profile on you doesn't seem like time wasted.
Any email Hillary sent or received that included someone with a state department address should still exist in the system somewhere as it would be covered under the state department email server's retention. If she emailed email@example.com and didn't cc: anyone, it'll be lost (unless the NSA has broken into his email and has a copy)
Well part of it too is that if you prosecuted Hillary, democrats would be calling for an investigation of former secretary of states Powell and Rice, neither of whom used official state department email but used their own for all their official business. It is unlikely they operated any differently than Hillary did, which is probably why career (i.e. not partisan appointees) state department officials never flagged Hillary's use of private email as a problem. They'd seen it all before, and to stick around a long time through administrations of both parties they know you can't be a boat rocker.
This isn't well reported in the press, and likely none of our international readers are aware of this. He was appointed by Obama because he had promised to appoint a couple republicans to cabinet level positions hoping that would help bipartisanship (obviously he was wrong there!)
Previously he was appointed Deputy Attorney General by George Bush, and before that was a federal prosecutor. Those who think "the fix is in" will still think that, but it wasn't due to a lifelong democrat whitewashing things at the FBI.
Look at all the scaremongering about skin cancer, to the point that some children are now vitamin D deficient because they never get any sunlight (and presumably don't get enough from their diet)
There's a happy medium between "laying in the sun for hours slathered in baby oil" and "wearing SPF 50 on all exposed skin even if you'll only be out in the sun for 10 minutes walking to lunch and back" but you wouldn't know it these days.
The problem with HDR is the same as that with offering audio with a high dynamic range. HDR audio like Dolby causes problems for people who have to turn up their sound to hear whispered dialogue and then get their eardrums blown out by explosions, so many end up enabling options for dynamic range compression. A lot of TVs have this enabled by default when you use the built in speakers, if you listen to a lot of commercial programming with an external sound system you end up needing a device like the Terk VR-1 which essentially performs dynamic range compression. If you visit a bar with sports on you can tell the ones who don't have this sort of device - the commercials are ridiculously loud and are almost painful to hear. This is better now than it was a few years ago (at least in the US) but they still make sure commercials are as loud as the loudest part of the regular programming, so it is pretty jarring to go from the hushed tones of a golf announcer to a local commercial for a car dealer that's practically screaming at you!
Now in order to get proper HDR video you will need a screen that is capable of far greater maximum brightness than existing TVs, because you're already maxed out at the low end by what people's eyes can see in dark scenes. You don't want to be forced to turn away from the screen and squint if you go from a nighttime screen to one depicting full daylight the next day, even though that's EXACTLY what you'd have to do in real life if you went from a dark room and walked outside at high noon on a sunny day. How will making your eyes hurt improve the TV watching experience?
What TVs need is not HDR but WCG - wide color gamut. Unfortunately that requires significant changes to the way we make TVs, as even the BT.2020 standard is unattainable by any TV ever made, even those in labs. And while BT.2020 is a big improvement over the amount of colors TVs can currently display, it still barely covers half of what the human eye is capable of seeing so we have a long long long way to go before TVs can reproduce the variety of color we our eyes can see in the real world! But that's how you get realism, not the "realism" of making me turn away from the screen and squint when the scene changes to bright sunlight, or making my ears ring when there's an explosion. Sure, that's realism, just not the kind of realism most people want from their entertainment!
Not sure where you got your crazy math figures. It says they they have 20 million ads displayed daily, which collectively attract 2.5 million clicks. Even if they weren't paid for ad impressions (they are) that would be $4/click not $205. But they aren't getting $4, because they are getting paid something for the 20 million ad impressions a day.
And India is only one of their markets, so even if a click is only worth less than their average in India it is worth more than their average in the US or other rich western countries.
The big gap in modern smartphones is the baseband, which the maker of the phone or its OS has no control over. They get it from whoever provided their baseband processor, typically Qualcomm. There are no open source basebands, which is why there is reputedly the ability for spooks to silently "call" a phone and have it serve as a bug by enabling its microphone without it ringing or anything showing up on the screen but no way to confirm or deny this, or prevent it even if confirmed. Such ability probably depends on the baseband being used, but if there's a backdoor for that in Qualcomm's for example it doesn't matter whether you have an iPhone, Samsung, Blackphone, Blackberry or whatever if it uses Qualcomm cellular chips.
There are rumors that Apple is including a "dark mode" in iOS 10 that will allow a simple one-touch method in control center of disabling cellular entirely while leaving wifi active, unlike airplane mode which disables all both cellular and wifi. This is already possible today but you have to enter the settings app, enable airplane mode and then re-enable wifi, and most people don't even know it is possible to do this. There's an umarked sixth button added to the five on the top of the control center that will supposedly be used for this. If that is implemented by powering off the baseband, you would be protected against this sort of thing and could still use wifi calling. If they do that, they'll basically be declaring open war on the authorities, furthering the battle they began this spring by refusing to go along with the FBI's demands.
Of course, this isn't a complete fix since it would only help in places where you have wifi (but still very good to prevent say corporate or government espionage listening in to meetings) A better fix may arrive eventually if the rumors are true that Apple will license Intel's baseband and build the hardware into their SoC. If they do that, they could develop the baseband software themselves and strip out any backdoors it may have. However, if you want absolute proof that's done Apple won't be good enough, you'll have to hope someday someone develops an open source baseband you could use on Android phones that have the right baseband hardware, and use a version of Android that has EVERYTHING Google-related stripped out.
There's no evolutionary reason that a queen wasp with more black marks on her face should be a better fighter, unless those with black marks are killed after losing a fight while those without black marks are not (maybe they will develop the black marks down the road?)
The question I have is what happens if a queen WITHOUT black marks wins a fight? They should cover up the black marks of a good fighter and find out.
So what if they do? If I sent you an email that had a PDF attachment that included an undisplayed encrypted JPEG child porn you would "have" child porn on your computer, but if you don't know its there or how to access it, so what?
The problem wouldn't be one guy doing it for one image, it would be a bunch of them deciding to outsource their distribution problem by embedding many many images in the blockchain. They only need tell each other where it is and how to decrypt it, which they could also do via bitcoin (especially if money is changing hands) or via other methods like embedding the location/key info in spam emails. The Message ID header would be perfect for this.
Who knows, maybe this is already happening and the authorities just haven't caught on yet. As always it is the dumbest criminals who are caught, the smartest ones always stay ahead. If this was being done, kiss bitcoin goodbye - it already has an association with criminal activity in many minds and something like this certainly wouldn't help. Anyone who wanted to ban it would have the perfect excuse "think of the children!"
70 million? Damn, I need to sell my stock before anyone else figures out their profit has dropped by 99.9%!
Sure, Apple could buy Imagination, but in doing so they buy their existing contracts so they'd have to keep developing GPUs for the others using them, as well as their other non-GPU product lines. Now it is possible that's why Imagination is slimming down, hoping it will entice Apple to buy them if they were told "we'd buy you if we could get just your GPU IP and engineers, we don't want to deal with these other product lines or your other GPU customers". That's a risky strategy, but Imagination has become so dependent on Apple the last few years that if they leave as a customer they will not survive anyway.
That's why Apple generally prefers to buy small start ups before they have any products. They don't want to inherit a bunch of other customers, but rather use the company's technology in their own products to differentiate them from other company's products.
Apple bought up some graphics patents and hired a bunch of former ATI GPU designers a few years ago, and speculation was they were going to design their own GPU core similar to how they design their own CPU core. The fact they have continued to use PowerVR means either:
1) theirs isn't ready yet
2) theirs isn't as good as PowerVR yet
3) Apple hired those people for something other than designing their own GPU or the stories were false
I think if the answer was 3, Apple probably would have wanted to purchase Imagination. If it is 1 or 2, and Imagination has been notified per whatever contract exists between Apple and Imagination that Apple won't be licensing PowerVR for the A10 (if their GPU is ready this fall) or the A11 (if next fall) that might be the sort of thing that would cause a company like Imagination to begin scrambling to cut costs, cause long time CEOs to quit before their stock options go underwater, etc. - i.e. exactly the sort of shakeups that have been happening with Imagination for the past six months...
It isn't signed by Apple or available from the Mac app store, but from third party sites. If it is considered newsworthy to have a backdoored app available from third parties, better clear out a lot of headline space as there are probably a thousand other such cases across many platforms.
Yes, I agree completely. Napster was super convenient, and free, so it was the best of all worlds but obviously couldn't last. When it went away and you had stuff like Limewire and later bittorrent it becomes too much of a pain versus the convenience of iTunes and friends, unless you have lots of time and little money (i.e. typical college student) Now with streaming services basically giving you "all you can eat" for a monthly fee (or free if you're willing to suffer ads) even if you're skint broke and unemployed it hardly makes sense to go through the hassle of illegal downloads.
With photos claimed to be taken by that 42 megapixel Lumia camera a years back?
Stuff like this just hurts their rep - people will figure "I guess the camera isn't really all that great if they have to cheat in their ads". Probably the marketing guy found it was too much of a hassle to get a prerelease phone to a photographer to take a proper picture, so they just had them take a professional photo and figured no one would be the wiser. How many potential customers will cross them off the list for shenanigans like this?
Because 32 bit x86 is so register starved, 64 bit x86 is faster in most cases. 32 bit ARM isn't register starved, but 64 bit AArch cleaned up the API and added some new stuff like CMOV instructions so it too may be faster in the majority of cases.
When Apple shipped the first 64 bit ARM SoC three years ago, the results of benchmarks run on it (as well as Apple's internal results) show it is faster running 64 bit code because of those API changes. Had it been slower, there probably would have been less of a rush for everyone else to catch up, since 64 bits is otherwise useless until you go beyond 4GB RAM in the device - something which is only now happening with a couple Android phones shipping with 6 GB.
If you have code that is very pointer heavy then doubling the size of the pointers shrinks the effective size of the cache and can make it run slower, but this is a pretty small effect in the single digits. If you have code for which this is a problem you can continue running the 32 bit version even on a 64 bit OS, at least until 32 bit support is ripped out of the CPU entirely (Apple will probably do that with the next major redesign of their 64 bit core, but I doubt anyone else will for a long time)
Companies like Red Hat dropping 32 bit support isn't going to make your Raspberry Pi stop working. It will only make it impossible for you to run purchase paid support from Red Hat for it. Someone will probably still compile 32 bit versions of it, just like CentOS recompiles Red Hat. Someone else will probably backport security fixes to the last supported 32 bit version so you can continue to using that.
By the time those sources dry up, you won't be able to buy a Raspberry Pi with a 32 bit CPU.
