Gresso case protects the iPhone 6 from bending


Credit: Gresso/The Gadgeteer

If you're still not convinced by the reassurances provided by Consumer Reports on the strength of the iPhone 6 in yesterday's post, you might like to add some reinforcement in the form of a Gresso case. 2 mm of aluminium at top, bottom & sides has got to help.

Consumer Reports revisits Bendgate



You've seen the video of an iPhone 6 Plus being bent, but what does it mean? How much force was actually applied? What about the same "test" applied to the Samsung Galaxy Note 4? Is the force the same? Greater? Less?

Consumer Reports steps into the breach with some objective tests of the the forces necessary to bend iPhone 6, 6 Plus, as well as some comparable top-of-the-line smartphones.

Testing concluded that:

IPhone 6 Plus is more resistant to bending than the iPhone 6
● Both are more bend resistant than the HTC One (M8)
● Both are scored lower than (in order of increasing bend resistance) LG G3, Apple iPhone 5, & Samsung Galaxy Note 3.

Perhaps most important is Consumer Reports closing comment: "While nothing is (evidently) indestructible, we expect that any of these phones should stand up to typical use."

Apple replies to complaints of bending iPhones


Credit: YouTube/Unbox Therapy/ABC

In response to claims of iPhone 6 Plus bending in normal use, Apple has responded that:

● 10 million iPhone 6s were sold over the first weekend after going on sale

● only 9 users have complained to Apple about bending phones

● strengthening includes:
◌ construction from a custom grade of aluminum
◌ tempered for extra strength
◌ high-stress locations reinforced with stainless steel & titanium inserts

iPhones are tested extensively before release, including the "sit test", which simulates sitting on a hard surface with the phone in the back pocket of a pair of tight jeans

Will it bend? — iPhone 6 Plus


Credit: MacRumors/PD13/Sydney Morning Herald

Claims have been appearing across the 'Net, that iPhone 6 Plus have been bending in users' pockets. These claims appear to be supported by photographs & the videos below. Some users claim their phones bend after a slight bump.

Is this an example of Apple's "premium construction"?

If yours does bend, don't try to bend it back. Can lead to a cracked screen — see the second video below.

Samsung's Power Sharing Cable lets you share power between devices


Credit: Samsung/phonedog

Keeping multiple mobile devices charged can be difficult. Samsung may have the solution with their Power Sharing Cable, which does pretty much what it says: allow charge to be transferred from one device to another. This would be useful if the device you need to use is about to die & no other charging source is available.

If you are thinking of using this, be aware that neither charge, nor discharge is 100% efficient. So there is a significant loss any time charge is transferred between devices.

Perhaps the most likely use is charging a smart watch from your phone.

Space elevator could be built by 2035, says new study


Credit: Extreme Tech

Space elevator? Yes — launching payloads into geostationary orbit is very expensive — around $20,000 per kilogramme using current technology. A space elevator could reduce this to $500.

A space elevator would be a cable, tethered at the equator, around 100,000 miles (160,000 km) long, with a counterweight at the end. An elevator car would climb the cable to geostationary orbit at an altitude of 22,236 miles (35,785 km).

What is needed to turn the theory into practice?

● Material for the cable. No existing material is strong enough.

● Energy to drive the elevator car. Energy to drive a conventional elevator is provided by conventional electric wiring to an electric winch which lifts the cable & the elevator car. A space elevator would consist of a stationary cable & an elevator car which would climb the cable. Electric wire or on-board energy supply would be too heavy. Microwave beam(s), possibly from both ends, may provide a solution.

● Design for the elevator car. This has to be a device which can lift its own mass, plus the mass of the payload, up the cable, without damaging the cable.

Are artificial sweeteners making us fat?

Artificial sweeteners seem, on the surface, to be a simple way to reduce calorie intake, & so lose weight. On the other hand, for some time, there have been suggestions that artificial sweeteners may be implicated in weight gain.

Perhaps equally counter-intuitive, is the importance of gut bacteria in maintaining health.

Emerging evidence suggests, that artificial sweeteners may cause weight gain by their influence on gut bacteria:

Android 5.0 L will automatically encrypt data

Some users store relatively little data on their phones: a few phone numbers & some old SMS conversations.

Others have much more. A politician once told me about his phone: "This is my office." A business woman: "I run my business on this thing."

Most people are somewhere in between, although there are a lot of people who believe they are in the first group, whose phones tell more about them than they realise. Some of this data actually belongs to others: "A few phone numbers," often includes a lot more, including physical address & birthdate. Such information is held in trust by the phone owner & shouldn't be passed on to others, even accidentally, as when a phone is lost or stolen.

Many (most?) phones contain data which exceeds the value of the phone itself. One way of protecting this data is to encrypt it. Android has had the capability to encrypt data, both on the device & an SD card, for some time. With Android L, encryption will become the default.

http://www.geeky-gadgets.com/android-5-0-l-will-automatically-encrypt-data-19-09-2014/

http://au.ibtimes.com/articles/566963/20140921/samsung-galaxy-note-4-s5-android-5.htm#.VB9d-dB_W2c

As indicated above, encryption has been an option on Android for some time. Not many have used this option. Reasons include:

● a PIN or password will be required every time the phone is woken from the locked state

● performance hit

● takes an hour or more to encrypt, depending on how much data is on the phone

● one way process — try it out, & don't like it, reversion will require a factory reset

"I turned the 5S over in my hands. It looks small now, I realized. Really small."

Your gadgets will never be secure — chase the hackers instead


Credit: Business Insider

It is fundamental to security that nothing is secure against a sufficiently determined & resourced attack. This applies to computer systems as well as physical security of premises & objects.

Mobile devices have their own peculiar own set of security risks. Smartphone manufacturers are under pressure to match the opposition. This means a shiny new phone with shiny new features, annually. There is not a substantial piece of software in existence without bugs. Some of these bugs are security related. Each new revision brings the risk of new bugs. Occasionally, even a bug-fix release will introduce a new bug.

Public WiFi networks represent a security risk peculiar to mobile devices.

First Formula E race today, Saturday 13 September 2014 – update



Update: video of the entire event.

Formula One has gone hybrid, so, time for a pure electric open-wheel formula. Enter Formula E.

Times (Beijing local):
Practice 1 — 08:15
Practice 2 — 10:30
Qualifying — 12:00
Race — 16:00

Race time in other time zones:
18:00 Australian EST
10:00 Berlin
09:00 London
04:00 US Eastern
01:00 US Pacific

In this first year, it will be a one-make formula, with all teams running Spark-Renault SRT_01E cars. Spark Racing Technology will build the cars, with components supplied by a who's who of F1:

● chassis — Dallara
● powertrain & electronics — McLaren Electronics Systems
● battery pack — Williams Advanced Engineering
● tyres — Michellin — 18 inch, with a single formulation for both wet & dry conditions

Figures for the size of the battery pack are hard to find, but 28 kWh (kilo Watt hours) has been suggested. Whatever the size, after 25-30 minutes, the battery pack will be exhausted. Drivers will swap to a second car for the remainder of the race. Battery swapping was dismissed on safety grounds, & recharging was considered to be too slow.

Towelroot app makes it easy to root Galaxy S5 & other locked Androids


Credit: geohot/LifeHacker

To root or not to root, that is the question ...

Several years ago, I had the first Android phone released, the HTC G1, which I rooted within days of purchase. At that time, it seemed the best course, as the stock G1 had a number of unnecessary restrictions, including no pinch to zoom & no WiFi hotspot.

Now I have a Samsung Galaxy S4, unrooted. Why no root? For me, the benefits are no longer there. Among other things, pinch to zoom & WiFi hotspot are both standard.

Some of the restrictions in stock devices are security measures. However, this can be fall down if a vendor is slow in releasing a security update.

Towelroot is a special case with respect to security, because it makes use of a vulnerability in many Android devices. The same vulnerability may be exploited by a piece of malware. Paradoxically, the best way to protect yourself against this exploit right now, is to exploit it yourself by rooting using Towelroot.

World population passed 7 billion late in 2011 or early in 20121. Around one third of those 7 billion live in varying degrees of wealth, with more than enough food. Indeed, the dietary habits of the wealthy third are characterised by growing incidence of obesity & overweight. This is the same third that is largely responsible for climate change, & will be most affected by peak oil.

Of the remaining two thirds, many have a reasonable standard of living & enough to eat. Some though, live in poverty with malnutrition & famine a constant threat. You've seen the photos.

World population is expected to pass 9 billion around 20501. I.e. two billion more than we can't feed now.

Apple iPhone 6 announcement just hours away

Apple's big announcement later today (10 a.m., 09 September US PDT) is universally expected to include the iPhone 6. Both 4.7-inch & 5.5-inch models are expected.

On a personal note: the suggested relocation of the sleep/wake button from the top to the side will represent the loss of the only feature I miss from my iPhone 4.

Carbon fiber wheels cut weight & boost efficiency (video)



Carbon fibre wheels are stronger & lighter to reduce:

● Wheel flex for improved handling & control — see the video above.

● Unsprung weight for improved handling, traction, & ride.

● Gyroscopic torque — see the video above, around the 6:20 mark.

● Rotating mass — a moving object has kinetic energy. In a vehicle, this energy is provided by the motor. Less energy requirement means more distance for the same cost. A lighter vehicle accelerates faster, & is more efficient, because it requires less energy from the motor to increase its speed, & so its kinetic energy. Unlike many other parts of a moving car, the wheels also have rotational energy. Once again, this energy comes from the engine. Weight saved in any part of a car improves its performance & efficiency. Weight saved in a lighter wheel improves performance & efficiency as for any other part of a vehicle, plus reduced rotational energy.

Archer fish shoots its prey (video)

Check out this amazing video of the archer fish shooting insects. Amongst the difficulties the archer fish has to overcome are: refraction at the air/water interface, which distorts the position of the insect; & the the necessary trajectory of the water stream through the air.

And the winner is — Nevada!


Credit: Tesla/Inhabitat

Tesla has been in negotiations for several months about the site of what will be the world's largest lithium ion battery factory. Candidates included Arizona, California, Nevada, New Mexico, & Texas. Cost will be $5 billion, $500 million of which will be provided as incentives from the chosen state.

http://www.teslamotors.com/about/press/releases/nevada-selected-official-site-tesla-battery-gigafactory

Tesla is establishing what has become known as the Gigafactory to push the price of electric vehicles (EVs) down. Price cutting is an aim of all business entities. In this particular case, it has a special purpose for Tesla's Model 3 (formerly Model E). Major design parameters are 200 mile range & $35,000 price point. To meet the Model 3 price point, EV battery price must fall by 30% [1]. Tesla's recipe for this price reduction is the Gigafactory.

Nevada won after a lengthy battle, including claims that California offered to waive certain environmental provisions [2].

To Tesla's credit, a spokesman replied, “It would be completely counter to the mission of the company to go against environmental legislation.” [3]

New "Dreadnought" dinosaur is the most complete specimen of a giant


Credit: Jennifer Hall/Scientific American

Dreadnought represents the most complete giant dinosaur discovered to date. "Giant"? At seven times the size of a Tyrannosaurus Rex, the term seems justified.

Most things that die are soon destroyed. Fossilisation, therefore, is a rare event. Meat is eaten by scavengers, often with bones broken up &/or moved considerable distances. Anything that's left will usually be broken down by agents of decay, such as bacteria & fungi.

Fossilization depends on some relatively rare event, usually involving rapid burial. Something small, say the size of a mouse, can be buried relatively easily. Burial of an entire animal seven times the size of a T. Rex is much less likely. Thus, fossils of large animals are usually more or less incomplete.

How did Dreadnought live? Given its size, it probably had nothing to fear from anything, even a predator like T. REx. Hence the name — dread nought — fear nothing. In feeding, that long flexible neck would have given it access to an enormous volume of plant matter. Modern day giraffes use a similar strategy on a much smaller scale.

Between imperviousness to attack & that enormous neck, Dreadnought probably spent its days planted in one spot, munching its way through all the food it could reach. After exhausting everything in reach, it would have moved a few metres & repeated.

Samsung Galaxy Note 4 announced


Credit: Samsung/BusinessWeek

A few features worth noting:

● Metal/premium construction/premium product/quality feel/etc — Samsung has a record of using less glass & metal than some other manufacturers in its phones. Reviewers have been banging on about this for years. With the Note 4, Samsung has incorporated some metal into the case. One of the reasons I abandoned the iPhone 4 was its fragile glass/metal construction. Have you ever dropped a phone? Is there anyone who hasn't? If I'm carrying hundreds of dollars worth of hardware, that I depend on for a large & growing list of functions, I'd prefer something with the resilience of a basketball. That's not going to happen, but a minimum of glass, & replacing metal with shock-absorbing plastic is a good start. Better is to put it in a case/cover as well, which, fortunately, can make glass/metal/plastic construction moot, if you manage to chose the right one.

● Ultra low power mode lets it run all night on standby mode with only 5% battery.

● Fast charge to 50% — between this, ultra low power mode & the very slightly larger 3220 mAh battery, this thing should never let you down.

● Increased resolution — screen size is unchanged at 5.7 inches, but resolution has been increased from 1920 x 1080 to 2560 x 1440. Attention all mobile phone manufacturers: it is some time since anyone has been able to see the individual pixels in the display of top-of-the-line mobile devices. Enough already! The only practical consequence of further increasing resolution is the negative effect on battery life.

● Front facing camera resolution has been increased from 2 megapixels to 3.7 MP. Focal length has been shortened, increasing the viewing angle to 120 degrees. Although this will let you fit more people into a selfie, increased fish-eye effect won't make them look any better.

● Rear camera — resolution increased from 13 to 16 megapixels & optical image stabilisation added, adds up to better images.

Google’s self-driving cars: not yet ready for prime time


Credit: Google/gizmag.com

Despite all the progress that Google has made with its self-driving-car, there are still many things that they can't do.

Google's system depends on detailed, up-to-date road maps (much more detailed than anything in Google Maps), so it is likely to be confused by changes to roads & traffic lights added since the last update. To date, only a small part of the the United States have been mapped to this degree of detail. Additionally, it has been questioned if mapping all of the US to the required level of detail & keeping the database up-to-date is even possible. Other things it can't deal with are construction zones & uncovered manholes.
