Apple updates Find My Friends with improved location-based alerts


Custom Search
The ugly tan leather and stitching is still there, but Apple has a new feature for its Find My Friends app that users will find pretty useful. Apple just updated Find My Friends so that users can setup up geofences and receive a notification once a friend leaves a designated area. Users have always been able to create location-based alerts, but Find My Friends 2.1 now lets users adjust the sensitivity of an alert by setting an exact distance threshold. The old system used a fixed zone that alerted you when someone was in your area, but now you can set your own radiuses to alert you about more specific things – like if a friend is in your neighborhood. Parents will probably get the most out of Find My Friends as a tool to keep tabs on kids. But it can be useful when you’re out on the town with friends and want to know when people leave, or if your significant other is on the way over and you need to clean your place up in a hurry. The free update is available in the App Store right now. -->

Security Microsoft Fixes Critical Internet Explorer Flaws


Custom Search

This month's Patch Tuesday round of Microsoft software updates will fix a pair of critical Internet Explorer flaws that put every current consumer version of Windows at risk of being attacked.


"Generally, when Microsoft patches IE, the patch is delivered as a single bulletin," said Andrew Storms, director of security operations at nCircle in San Francisco.
"The planned delivery of two separate IE bulletins has my 'Spidey' senses on alert," he said. "I'm sure other IT security teams are wondering exactly what kind of IE valentine we're going to get."
All supported versions of Internet Explorer, from IE 6 on Windows XP to IE 10 on Windows 8 and the tablet-only Windows RT.

Browsers have become the target of choice for malware writers, who embed hidden code in corrupted websites to infect visiting computers via drive-by downloads.
Other critical patches in this month's round include two for Windows XP, one of which also affects Vista, and another for Microsoft Exchange Server, the enterprise software that runs email in companies.
Microsoft never says exactly what's being patched before it pushes out its updates, which normally come on the second Tuesday of every month. (The highest-priority flaws get fixed in emergency "out of cycle" updates.)

We'll have more information about what's being specifically patched once Microsoft pushes out the update tomorrow (Feb. 12).

Seven other flaws being patched are deemed "important" by Microsoft.

"Hackers could phish users and then leverage 7, 8 and 9 to get system-level control of their machines," said Alex Horan, senior product manager at Boston's CORE Security. "That is essentially a worst-case scenario and a potential knockout punch for security personnel."Four of those patches — bulletins 7, 8, 9 and 11 according to Microsoft's pre-release documentation — involve privilege escalation, in which a user or process with limited abilities can be bumped up to administrator level, with power to make changes to the system.

Home and small-business users of Windows should enable automatic updates in Windows Update, which is found under Control Panel. Larger enterprises usually choose to implement their patches manually.

Bio-batteries will soon be reality


LONDON: Bio-batteries have now taken a giant leap towards becoming a reality. British scientists have made an important breakthrough in the quest to generate clean electricity from bacteria. The study has found for the first time that it is possible for bacteria to lie directly on the surface of a metal or mineral and transfer electrical charge through their cell membranes. This means that it is possible to tether bacteria directly to electrodes - bringing scientists a step closer to creating efficient microbial fuel cells or bio-batteries.Researchers from the University of East Angliaare working with a marine bacteria called Shewanella oneidensis. They created a synthetic version of this bacteria using just the proteins thought to shuttle the electrons from the inside of the microbe to the rock. They inserted these proteins into the small capsules of lipid membranes such as the ones that make up a bacterial membrane. 
Then they tested how well electrons travelled between an electron donor on the inside and an iron-bearing mineral on the outside. Lead researcher Dr Tom Clarke said "We knew that bacteria can transfer electricity into metals and minerals, and that the interaction depends on special proteins on the surface of the bacteria. But it was not been clear whether these proteins do this directly or indirectly through an unknown mediator in the environment." "Our research shows that these proteins can directly touch the mineral surface and produce an electric current, meaning that is possible for the bacteria to lie on the surface of a metal or mineral and conduct electricity through their cell membranes. This is the first time that we have been able to actually look at how the components of a bacterial cell membrane are able to interact with different substances , and understand how differences in metal and mineral interactions can occur on the surface of a cell." Dr Clarke added "These bacteria show great potential as microbial fuel cells, where electricity can be generated from the breakdown of domestic or agricultural waste products. Another possibility is to use these bacteria as miniature factories on the surface of an electrode, where chemicals reactions take place inside the cell using electrical power supplied by the electrode through these proteins."Share your views

South Australian first to get OneTab smartphone app to pay for hotel tab

Custom Search
SMARTPHONES can now be used to set and settle food and drinks tabs at key hotels and pubs around South Australia.

South Australians will be the first to give the Australian-first system a go.
OneTab is described as a convenient, fast and secure mobile payment system that allows you to set up, track and pay for food and bar tabs on your night out - eliminating the need to for patrons to ever hand their credit card over a bar and also protects hotels from stolen or fraudulent cards or cards with inadequate balances.
Tess Wheeler, 22, said she loved the new app, which was easy to use and quick.
"Often, I leave the pub and I have forgotten to sign off and collect my card," she said. "The app just helps with not having to think about returning the next morning to tidy things up."

The app is free to download and integrates with the point-of-sale system of the venue.
All patrons need to do is find their venue on the app - and there are ten hotels and pubs in Adelaide that will have this system, including the Robin Hood Hotel - open a tab, set a credit limit, once the card balance is verified, a code is generated, which needs to be shown to the bartender.
They can then order as normal; when ready to move on, just click pay.
OneTab, developed by Queensland-based Paul Wyatt and Scott Cross, is linked to SA-based national hotel point-of-sales solutions provider H&L Australia.
Mr Wyatt said OneTab helps boost credit card security.
"We just thought there had to be a better, safer way to deal with opening a bar tab and after a year of working out how to commercialise the concept, here we are," he said.
Burt Admiraal, director of H&L Australia, said the OneTab concept was simple, effective and free.
"Using credit cards as security for bar tabs really does cause issues on both sides of the bar."
Mr Wyatt said, "OneTab takes physical handling of credit cards out of the equation so you can close your tab from anywhere without waiting for staff and puts an end to leaving your card behind.
"You approve all purchases added to your tab in real time and receipts can be sent directly to your email."
Mr Admiraal said South Australia was chosen for the launch to target the key "smartphone savvy" demographic.
There is a similar application available in the US called TabbedOut.
