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.

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

Big screen iPhones — is it what Apple users needed?

Credit: CNET

CNET takes a look at the big screen iPhones. What do they think? A bit more to the point, what do they think of previous iPhones?

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

A few years ago, I swapped an iPhone 4 for a Samsung Galaxy S4 largely for that reason. No pun intended.

MIT robotic cheetah

Previous attempts at mechanical quadrupeds have used an internal combustion engine driving a pump & hydraulic system. This is both noisy & inefficient. MIT's effort is all-electric & can hit 10 mph (16 kph) untethered, with a theoretical limit of 30 mph.

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.
