Towel thieves, consider yourselves warned. Those handy travel-sized hotel towels may be useful to take with you (and not bring back) when you head out for a day at the beach, but soon that will no longer be an option.
Hotels nationwide have tired of a trend that leaves them missing 5 to 20% of their towels in any given month.
Enter Linen Technology Tracking, a Miami-based company that patented a washable Radio Frequency Identification (RFID) chip for hotels to sew into towels, robes and bed sheets. The chip can trigger an alarm if a guest tries to take a tagged item from the premises. The New York Times reports that three hotels in Honolulu, Manhattan and Miami have introduced the system but wish to remain unnamed.
William Serbin, the executive Vice President of Linen Technology Tracking tells the New York Times that high cotton prices led to costlier towels which served as motivation for developing an anti-theft system. He adds that the technology has a double purpose — in addition to catching thieves, it helps hotels monitor linen demand and adjust their supply accordingly.
It’s a successful system. The Honolulu hotel has saved nearly $15,000 since implementing the tags last summer and their monthly towel theft is now less than a quarter of what it was before. Can travelers hope for rapid rate reductions as a result? Probably not, but NewsFeed can dream.
Tesla CEO Elon Musk unveiled a prototype of the company's new Model 3 in a ceremony on Thursday night in Los Angeles.
Leading up to the event, droves of future customers waited in line at the company's showrooms and online to place $1,000 deposits on the company's most affordable model to date.
On Friday, Musk announced on Twitter that his company generated roughly 180,000 orders in 24 hours. Hours later, the total surpassed 230,000.
And by Saturday morning, orders were over 250,000. (He promised more updates as he gets them.)
By Musk's math, at just 180,000 orders, the automaker booked about $7.5 billion in future sales. That's based on a price of $42,000 a car.
The car's base price is about $35,000, but it is expected to launch with versions that cost well above that.
Musk is, of course, making some assumptions there, namely about how many of those who placed deposits will actually buy the car when it's ready in 2017 or 2018.
Venture capitalist David Pakman, however, tweeted a different take that still leads to some impressive numbers. If the company books 200,000 preorders and actually sells cars to 70% of those buyers at the lowest-possible price, then it means the company has just locked in $4.9 billion in future sales, with little money spent on marketing.
And regardless of the eventual sell-through, what is already clear is that — with the 200,000 preorders that Musk announced — Tesla has raked in $200 million in interest-free cash.
The company wasn't immediately available for comment on what it planned to do with those funds.
Tesla shares rose 5.2% to about $242 in early trading on Friday, but gave up some of those gains later in the day. The stock is up over 60% from a February low — in part in anticipation of the new car.
Meeting the hype But if Tesla will live up to the hype — one analyst on Friday raised the price target on Tesla to $500 a share, according to Bloomberg — then the company still has to execute on timing and delivery of the new cars.
Tesla is promising to deliver the cars starting in late 2017, but as Business Insider's Bryan Logan notes, all of Tesla's previous vehicles — the Roadster, the Model S, and the Model X SUV — arrived late, for various reasons.
The company also has to sustain sales past the initial hype. Those deposits are fully refundable, which means that many buyers could, by late 2017 or 2018, lose interest in the car or be unable to follow up with the additional $34,000 — and up — that it will take to actually buy one.
Morgan Stanley's Adam Jonas recently predicted that Tesla would fall well short of the company's target of 500,000 annual unit sales by 2020. Jonas, a noted Tesla bull, suggested that the company would be selling closer to just under 249,000 cars annually by 2020. But that was before Thursday's bookings.
With Tesla having delivered more than 50,000 cars in 2015, reaching roughly a quarter-million would see production increase five times as much by 2020. That means that even with Jonas' conservative projection, the Model 3 will play a very substantial role in the company's future.
I ask because back in 1985 Paul David wrote a paper (pdf) in which he claimed that the Qwerty keyboard was inferior to alternatives such as the Dvorak one. However, the Qwerty keyboard was adopted for reasons which aren’t relevant today – for example, in slowing typists down it reduced the frequency with which typewriter keys collided with each other. And it persists because the short-run costs of becoming accustomed to a new keyboard deter us from shifting despite the long-term advantages of doing so.
Although some people quibble with David’s example – it’s unclear whether Dvorak keyboards are actually better – the general story here is plausible. We can become locked into inferior (pdf) technologies which were first adopted by historical accident because the costs of switching to better alternatives are high. Robin Cowan claims (pdf) that this is the case with nuclear power plants in the US*.
Now, here’s the thing. If Brexit’s intelligent advocates are right, the same thing is true for the EU. They argue that our relationship with the EU is sub-optimal and might become more so and that we’d be better off (pdf) with globally free trade. However, there are short-term costs to shifting: the uncertainty caused by Brexit could dampen investment both directly and, perhaps, by raising borrowing costs.
In this sense, the EU is like the Qwerty keyboard; it’s inefficient, but we’re locked in by historical accident and the short-term costs of changing.
Which poses the question: are those short-term costs worth incurring? My hunch is no (pdf). Even if we achieved good free trade agreements, it would take many years to reap the benefits of them simply because companies would have to invest in export sales efforts in unfamiliar parts of the world, thus overcoming the force of gravity. Dietz Vollrath’s general point – that it takes many years for improvements in potential GDP to feed into actual GDP – applies especially here.
I fear, therefore, that Brexit’s advocates are under-estimating the costs of adjustment.
They’ve got form for doing so. Back in 1984 Patrick Minford argued in favour of pit closures on the grounds that unemployed miners would find work elsewhere – that the adjustment process would be swift enough to more than offset the short-term hardship. He was wrong: ex-mining communities are still depressed.
And here’s my suspicion. Perhaps in supporting Brexit free marketeers are making a mistake they often make: they under-estimate how slow and costly the transitions can be from one equilibrium to another.
* My favourite example is Brian Arthur’s story of how steam-powered cars were hard hit by an outbreak of foot and mouth disease in 1914 which closed the water troughs from which they refuelled, thus locking us into petrol engines.
Google has abruptly killed off one of its April Fools' Day "jokes" after it caused outrage online, with multiple people claiming that it lost them their jobs.
The premise of the joke was simple. In Gmail, next to the standard "Reply" button, Google added a "Mic drop" button. Using it would reply to the email, archive it — and also add a GIF of a "Despicable Me" minion dropping a mic.
"Email's great, but sometimes you just wanna hit the eject button," Google wrote in a tongue-and-cheek blog post explaining its purpose. "Like those heated threads at work, when everyone's wrong except you (obviously). Or those times when someone's seeking group approval, but your opinion is the only one that matters (amirite?). Or maybe you just nailed it, and there's nothing more to say (bam)."
But the joke backfired — fast.
Its placement directly next to the default Reply button — replacing the "Send and archive" button — meant it was easy to click by accident, especially if a user didn't understand what it was. Google's product forums are full of furious users claiming they pressed the button by accident, often on important professional emails.
Here's how the mic-drop GIF can look in a wildly inappropriate email:
One user, Abdus Salam, wrote that he had lost out on a potential job because of the GIF. "This mic drop is perhaps the most stupid thing you could possibly come up with. I have been interviewing with this company for 3 months now and mistakenly sent the email directly to guess who? The HR! Why would you do that? I so want this job; was due to start on Monday!"
Meanwhile, Allan Pashby wrote: "Thanks to Mic Drop I just lost my job. I am a writer and had a deadline to meet. I sent my articles to my boss and never heard back from her. I inadvertently sent the email using the "Mic Drop" send button. There were corrections that needed to be made on my articles and I never received her replies. My boss took offense to the Mic Drop animation and assumed that I didn't reply to her because I thought her input was petty (hence the Mic Drop). I just woke up to a very angry voicemail from her which is how I found out about this 'hilarious' prank."
And The Telegraph found a third angry user who claimed: "I just sent off an email with my resume to the first person who wanted to interview me in months ... I clicked the wrong button and sent it with the mic drop. Well, I guess I'm not getting that job. Words cannot describe how pissed off I am right now. I'm actually shaking. One click, ONE CLICK and I lost the job. Goddamnit. Not funny, google. I'm going to go cry now."
Of course, considering it is April Fools' Day, it's difficult to verify whether all these stories are true. But even if some are made up, it's pretty clear there's anger over the joke. And when you consider the sheer scale of Gmail, it's not hard to believe that the feature has caused serious problems for some people.
Google has pulled the plug, removing the feature from Gmail. In a statement, a company representative said: "Well, it looks like we pranked ourselves this year. 😟 Due to a bug, the MicDrop feature inadvertently caused more headaches than laughs. We’re truly sorry. The feature has been turned off. If you are still seeing it, please reload your Gmail page."
The Government’s Digital Economy Minister, Ed Vaizey, risks shunning smaller ISPs by proposing a significant shift in the broadband and phone market, which on the upside could mean an end to separate line rental charges and clearer pricing. But you’ll still pay for the line.
According to reports (here and here), Mr Vaizey has summoned BT, TalkTalk, Sky Broadband and Virgin Media to attend a roundtable discussion before Parliament goes on its summer recess (21st July 2016). The discussion will focus on how to kill off the “outdated” system of line rental charges, which Vaizey describes as an “analogue billing system in a digital world.”
The discussion filters into the recent proposals for new advertising rules (here and here), which would force ISPs to provide customers with a single package cost for both broadband and line rental combined (instead of showing them separately). But this rather ignores how the market actually works, with line rental prices generally being reflected via one of three methods or a combination.
Line Rental and Broadband Combinations
1. Broadband and line rental / phone are both sold as separate products, albeit often operating over the same network (i.e. BTOpenreach) and they usually still need each other in order to work. You can often mix each between different ISPs, thus single pricing would NOT work here (hundreds of ISPs offer this).
2. Broadband and line rental (phone) are sold as a bundle from the same ISP (single pricing would work for bundles).
3. Broadband is sold standalone without a phone / line rental service, with the physical line already being part of the main price rather than a separate tacked-on product (most common on pure fibre optic (FTTP/H) services where a traditional separate copper phone line is not required).
The other mistaken assumption appears to be that what the Government proposes might magically result in consumers saving almost the entire cost of the line rental component off their broadband bundle, which is incorrect.
Mr Vaizey said:
“You get these headline prices which are misleading. People should pay for what they use. If the companies come up with a different pricing structure, that is fine, as long as they can see what they are paying for. Some people want to get rid of their landline entirely and pay for their broadband.”
An Ofcom spokesman said:
“Ofcom shares the Government’s concern in this area. We believe prices need to be clearer. Broadband advertising should show the full cost up front, including any set-up fees. So we are working closely with our sister regulator, the Advertising Standards Authority, which expects to make changes in the summer.”
Like it or not, every ISP that uses a fixed line service (broadband, phone etc.) must cover the cost of the underlying physical line (the cable that enters your property) and maintenance in some way. In other words, if line rental is taken out of the equation then the bulk of that cost will simply shift to broadband and you’ll still be paying more or less that same “rip off” price (broadband and line rental are actually quite affordable in the UK, when compared to most other countries).
What the Government proposes might also make life more difficult for the hundreds of smaller ISPs that sell phone and broadband as optional / separate services above (see this feedback from ISPs). An enforced single-price model may actually risk losing choice from the market because not everybody wants to take their broadband and or phone / line rental from the same provider.
Bundles remain a relatively new invention and one that tends to have been most embraced by the bigger ISPs, while the mass of smaller providers (hundreds of them) still sell broadband and phone separately (you can’t force a one price model on these, especially if they don’t even sell line rental).
Ofcom also suggests that the set-up fee should be included into the price, which might require some big changes since the cost of setup often varies depending upon the end-user’s circumstance (migrations are usually much cheaper than costly new line installs etc.). ISPs could of course adopt a shared pricing model (same price for everyone), but that would also mean higher prices (i.e. if everybody pays the same price then migrating customers would effectively be subsidising those who want an expensive new line etc.).
Equally there’s a huge question mark over whether or not the big ISPs would use this type of single pricing as an excuse to quietly get rid of the cheaper Line Rental Saver discount, which is where you can save the equivalent of up to around £2 per month off the line rental cost by pre-paying for a year in advance.
Conclusion The 2014 Digital Communications Infrastructure Strategy proposal did moot a future in which traditional copper “phone” lines may become a thing of the past (here), with BT further hinting that phone services may eventually take a more VoIP form and be optionally sold over the top of your broadband connection. But that wasn’t expected to happen for another 9-10 years or so.
Lest we not forget the forthcoming Single Order Generic Ethernet Access (SOGEA) product that Openreach are developing (here and here), which is essentially a standalone / naked FTTC (VDSL) “fibre broadband” package that would be sold for a single price.
SOGEA represents a shift in Openreach’s thinking, where you buy the broadband first and the phone service as an add-on (opposite to today’s model). But the “Alpha” trial for this won’t start until October 2016, with a “Beta” trial set to follow in April 2017 and the final Pilot due in August 2017 (commercial launch in 2018?). So it’s a long way off and is currently just one product.
In other words the Government has a huge challenge in trying to fundamentally change how broadband services are sold and it remains to be seen whether or not they can achieve this without inadvertently removing choice and flexibility from the market. In keeping with that they must also make sure to engage smaller ISPs and to understand the technical reality of how such services are sold by suppliers in the first place.
At the end of the day there’s really no reason why ISPs cannot promote their pricing in a clearer way by being more transparent with what they’re doing / discounting. Similarly there is also nothing inherently complicated about line rental, so long as it’s presented and costed clearly alongside the broadband cost when applicable.
We’d love to see an end to confusing offers, but forcing the removal of line rental may have too many unintended consequences and cause frustration when consumers, many of whom hold the mistaken belief that they will save money with its removal, suddenly realise that its cost has simply been transferred to sit under the heading of “broadband“.
In the future we do expect to be buying broadband as the primary product and phone services as an add-on (VoIP), which will reverse the current trend. But as SOGEA shows, Openreach and its ISPs aren’t yet ready to completely make that transition and any new advertising rules must recognise the wider market flexibility and consumer choice.
Having a drawer filled with dark chocolate will boost your brain – we really mean it! But it's not the only food to do so. From folklore medicine to Aztec warrior usage, we unveil five snacks that have a long history of increasing concentration.
Sunflower seeds will help boost concentration In 2009 the University of California estimated that we are bombarded with 34GB of information a day, twice as much as 30 years ago – a figure that has undoubtedly skyrocketed since the study took place. Office workers, meanwhile, are interrupted on average every three minutes.
Small surprise, therefore, that our concentration spans are shrivelling. In fact, while the average attention span for the notoriously ill-focused goldfish is nine seconds, people now generally lose concentration after eight seconds. This further highlights the affects of an increasingly digitalised lifestyle on the brain.
There have been numerous suggestions for increasing concentration, spanning keeping your email inbox tidy to mastering the art of time management. However, what if you could boost brain activity simply by nibbling food? Can it actually sharpen our minds? Well, the answer is yes, more or less.
That's what online health retailer MuscleFood.com suggested as it compiled a list of snacks that you should be eating while at work.
We've selected five of the best brain power inducing suggestions which we could back up through research, or had a long history of being used to clear "brain fog":
(1) Sunflower seeds Sunflower seeds are high in dopamine – a brain chemical involved in increasing motivation and concentration. Its offered Vitamin E can actively protect brain membranes from damage and is known to boost memory as well.
A healthy nervous system means both clearer and happier thinking, according to research. In fact, Readers Digest's "Fight Back with Food," suggested under-consumption of omega-3-rich foods may actually lead to depression.
And according to John Heinennan in the "Encyclopedia of Fruits Vegetables Herbs", this is the way they work: "Tobacco releases stored sugar (glycogen) from the liver and this perks up one's brain. Sunflower seeds provide calories that give the same mental lift."
(2) Eggs Waking up slightly earlier to cook eggs for breakfast will help you in the long run. The protein inside eggs is the highest-quality protein of any food. That protein can make you feel fuller for longer periods of time, causing you to maintain more stable blood-glucose levels. The high-quality protein in eggs also forms a necessary component of important neurotransmitters, such as dopamine and norepinephrine.
These are chemicals that brain cells use to communicate among themselves. The net effect of all these processes on the brain is an enhanced feeling of energy and alertness.
Researchers at Boston University also found people who got plenty of choline (present in eggs) in their diets performed better on memory tests and were less likely to show brain changes associated with dementia.
(3) Chia seeds Chia seeds benefit the body by delivering maximum nutrients with minimum calories and promotes digestion, energy and detoxification. Its history, however, is quite intriguing. Aztec warriors ate chia seeds to give them high energy and endurance, suggesting that just one spoonful of chia could sustain them for 24 hours.
Similarly, the isolated tribe of Tarahumara Indians is known for a remarkable feat. They often run for hundreds of miles and scale mountains without injury or rest. Their legendary endurance puts gold medal Olympic marathon runners to shame.
Many believe the chai they constantly keep with them is so packed with nutrition, that one or two mouthfuls will fuel a Tarahumara runner for an entire day.
(4) Rosemary In folk medicine, rosemary has been associated for centuries with helping people develop a good memory. In fact, Ophelia in Hamlet told her brother Laertes: "There's rosemary, that's for remembrance." Its link to extending brain power also includes boosting concentration.
The Tudors also believed that rosemary had the power to enhance memory. It's no speculation though, as researchers found that by sprinkling rosemary over snacks, or, strangely enough, by sniffing it, will enable people to remember to do things. It's a pretty nifty tool for the workplace!
In fact, sniffing it could increase your cognitive memory by 75 per cent.
(5) Dark chocolate Rejoice! There's now a reason to stock up on dark chocolate. And it's exactly because of the happy feeling you're experiencing upon hearing that fact that chocolate has made it onto the list: It boosts your mood. Furthermore, it's known to significantly increase your focus.
Researchers at Northern Arizona University tested the mental responses of participants who ate chocolate of various levels of cacao content. Participants who ate chocolate with 60 per cent cacao – the minimum level of cacao to count as dark chocolate – were more alert and attentive. The downside was increased blood pressure.
There may be a way around that though. Those who consumed dark chocolate with the amino acid L-theanine, which is a relaxant found in green tea, experienced an immediate drop in blood pressure. There you go, a heady mix of dark chocolate and green tea will do the trick!
Apple just announced a new, 9.7-inch iPad Pro — smaller than the original, gigantic 12.9" iPad Pro model, but with the same support for the Apple Pencil stylus and with a better camera.
The new iPad Pro starts at $599 for a model with 32GB of storage, and $749 for 128GB. It starts shipping on March 31st, with preorders opening this week.
Apple is doubling down in the iPad Pro's ability to replace a traditional laptop, in both the bigger and smaller sizes. And the company isn't shy about using it to steal away Microsoft users.
"You might not know this, but the majority of iPad Pro users are coming from a Windows PC," says Apple's Phil Schiller.
At 9.7 inches, the new iPad Pro has the same screen size as Apple's very first iPad, released in 2010. But just like its bigger cousin, the new iPad Pro is designed around productivity and high-end graphics and audio. And it supports a smaller version of the Apple Smart Keyboard cover for the iPad Pro.
Schiller hypes up the new iPad Pro's specs, including an A9X chip, which he bills as the company's fastest processor ever. It also has "pro audio" speakers, and tons of graphical juice under the hood for gaming.
"That's more than an [Microsoft] Xbox 360, in a device you hold in your hand," Schiller says.

The new iPad Pro also boasts a retina screen, including a new technology that adjusts the screen's reflectivity based on the level of light, to make it more like working with a sheet of real, actual paper.
It also sports a 12 megapixel camera that also lets you take 4K super-high resolution video, which is better than the original iPad Pro.
The iPad Air 2, which used to be Apple's flagship 9.7-inch iPad, is sticking around — but it's getting a price drop to $399. The iPad Air 2 hasn't gotten a refresh since late 2014, so the new iPad Pro is going to be the prime choice for the performance-conscious.
That means the iPad line starts at $269 with the smaller iPad mini, goes up to $399 with the iPad Air 2, $599 for the new, smaller iPad Pro, and $799 for the 12.9-inch iPad Pro. The original, gigantic iPad Pro is also getting a 256 gigabyte model that starts at $1099.
Launching a new iPad Pro is a bold move, given that the original model failed to set the tablet market on fire since its late-fall release.
Still, given that one of the biggest criticisms of the iPad Pro was its huge size — and given that Apple's Phil Schiller says that the 9.7" screen size is the best-selling iPad screen to date— Apple is clearly hoping a new form factor will kickstart a boom.
Apple unveiled its latest iPhone, the iPhone SE, at an event on its Cupertino, California, campus on Monday.
It's going to cost $399 without a contract, or free with a two-year contract — significantly less expensive than other new iPhones were when they first launched.
You can preorder it on March 24, and it will go on sale in stores on March 31.
The SE has a similar body to the iPhone 5S, but with updated components.
"It's got advancements that will make it the most powerful 4-inch phone ever," Greg Joswiak, head of iPhone marketing, said.
According to Apple, the SE will have the same processor as the 6S. The A9 chip in the SE will allow it to turn on when a user says "Hey Siri" and will enable Apple Pay, which is a way to use an iPhone to pay at certain credit-card terminals.
The iPhone SE will also have a 12-megapixel camera, which should be as good as the camera currently in the iPhone 6S. It will also be able to take Live Photos, an Apple photography feature that adds subtle movement to a still picture.
Full specs are available from Apple's website.
The SE comes in rose gold, a pinkish finish previously available only on the iPhone 6 and 6S.
One banner feature the SE will lack is 3D Touch, a new type of multi-touch technology that lets the iPhone sense how hard the user presses down.
Apple is hoping that the iPhone SE can tap into an underappreciated market — people who like small phones — and can help turn around sluggish iPhone sales trends by accelerating existing users' upgrade cycles.
Data show that one-third of iPhone users are still using a 4-inch iPhone, and analysts have predicted that Apple could sell as many as 15 million iPhone SE units in its first year.
Service providers aren't to be trusted, Snowden says at Free Software Foundation's LibrePlanet event at MIT
NSA whistleblower Edward Snowden opened the Free Software Foundation's LibrePlanet 2016 conference on Saturday with a discussion of free software, privacy and security, speaking via video conference from Russia.
Snowden credited free software for his ability to help disclose the U.S. government's far-reaching surveillance projects – drawing one of several enthusiastic rounds of applause from the crowd in an MIT lecture hall.
"What happened in 2013 couldn't have happened without free software," he said, particularly citing projects like Tor, Tails (a highly secure Linux distribution) and Debian.
Snowden argued that free software's transparency and openness are cornerstones to preserving user privacy in the connected age. It isn't that all commercial products are bad, nor that all corporations are evil – he singled out Apple's ongoing spat with the FBI as an example of a corporation trying to stand up for its users – merely that citizens should not have to rely on them to uphold the right to privacy.
"I didn't use Microsoft machines when I was in my operational phase, because I couldn't trust them," Snowden stated. "Not because I knew that there was a particular back door or anything like that, but because I couldn't be sure."
Private data, these days, only stays private at the sufferance of the major tech companies that administer devices and services, he argued. Given the increasing centrality of smartphones and social networks and the myriad of other digital communication methods to modern life, simply trusting that those tech companies will protect their users' privacy is insufficient.
Relying on corporations to protect private data is bad enough in a vacuum – but Snowden pointed out that many tech giants have already proven more than willing to hand over user data to a government they rely on for licensing and a favorable regulatory climate.
He particularly singled out service providers as being complicit in overreaching government surveillance.
"We can't control telecom partners," Snowden stated. "We're very vulnerable to them."
However, protecting privacy is gaining mindshare, he added. Increasingly, a digitalpublic concerned with keeping its private data to itself is getting behind the idea of pushing back on the tech industry and the government.
"We're no longer passive in our relationship with our devices," he said.
But awareness must be raised still further, and alternatives have to be offered by the free software world. Encrypting everything that can be encrypted is one way to preserve privacy, as is self-hosting.
"Even mass surveillance has limits," Snowden said.
Even if tech companies don't actively partner with the government on surveillance, there are huge vulnerabilities in important systems, he noted. A need for stability compromises the ability to patch security holes in anything like a timely manner, particularly in the enterprise.
"It's not just a question of stable – stable is important," Snowden said. "But increasingly, due to the pace of adversary offensive research [being] so fast, that if our update cycles are not at least relevant to the attack speed, then we're actually endangering people."
The head of Apple's operating system iOS confirmed that open but unused apps do not affect iPhone battery life after a customer emailed boss Tim Cook.
The customer from Ohio, known as Caleb, asked Mr Cook whether closing down "multitasking apps" improved battery life and whether it was something the chief executive did himself.
Senior vice-president Craig Federighi replied "no and no".
However, other smartphone batteries can benefit from app closure.
Microsoft advises Nokia Lumia owners to close apps that aren't in use on a web page about extending battery life.
Android creator Google suggests identifying and closing apps that are not often in use but warns that frequent use of its Overview device manager to do this will in itself drain the battery.
"You can view and optimise your device through closing running apps and uninstalling unnecessary apps," said Samsung in an announcement about a new "smart manager" app for the Galaxy 6.
While many Apple users do shut down apps in the belief it extends the iPhone battery this is not advice explicitly given by the firm itself.
It only recommends disabling apps from carrying out background refreshes in a list of tips about saving power.
The BBC has contacted Apple for comment.
Former chief executive Steve Jobs would sometimes reply directly to unsolicited emails - generally in very few words - but Tim Cook appears to be less forthcoming.
Caleb shared his unusual correspondence with the website 9to5mac.
"On a technical level, most of the apps are either frozen in RAM or not running at all, the system just displays them as a history for consistency. This is why the battery life impact is negligible," reporter Benjamin Mayo notes.
Caleb himself appears to be surprised by the attention the emails received.
"That went more viral than I thought it would," he tweeted.
