Google Releases Latest Video Chat App Called "DUO"

The company launched a free new video calling service called Duo on Tuesday that's not unlike Apple (AAPL, Tech30)'s native video calling app. But it comes with a few bells and whistles to help the app stand out. The name Duo comes from Google's desire to focus on one-to-one video calling. That's why there is no group calling function -- something Google Hangouts originally made famous.




But Duo allows users to make calls between iOS and Android devices -- something FaceTime can't do. It also excels in a few other areas, such as its user interface and the overall quality of calls.
Duo opens with a split-screen view of your front-facing camera and a group of recently dialed contacts -- it lets you see what you look like even before you place a call.

This is important because as soon as you dial a contact's number, they'll get a sneak peek of you in real time, even if they decide not to answer. Google (GOOG) calls this optional feature "Knock Knock," and it acts like a digital peephole.
Knock Knock intends to give the receiver time to prep before picking up. Although Android users will be able to see this video preview on the lock screen, iPhone users will have to tap "Preview" first or be in the app.

Take up to a minute to pick up

 Not sure if you want to pick up or are in another room? Duo will ring your phone for up to a minute before it gives up. When we tested this, FaceTime rang a recipient for about half that time.

 Give the caller your undivided attention

 Duo promises a more crisp experience than other video messaging platforms, and during CNNMoney's testing of the app over a cellular connection, it delivered on those claims.
Google's app also puts less emphasis on you during calls, so it's easier to pay more attention to the other person. Duo shrinks the selfie view and docks it on the bottom left corner of the screen. When using FaceTime, we had a greater tendency to look at ourselves via the selfie screen, which was more prominently placed in the top right corner.

There are other features that reinforce giving the other person undivided attention, too. For example, there's no way to pick up another call if one comes through. Instead, Google sends them a message saying you're unavailable. When you've hung up, you'll get a notification highlighting the missed call.
While this might be inconvenient if you're expecting another call, it's nice to know you can't be interrupted.

Security Alert; Bart Ransomware Bypasses Corporate Firewalls

A new ransomware variant has emerged that’s similar to widespread threats such as Dridex 220 and Locky Affid=3, but uses a security-evading technique that may allow it to attack organisations protected from other malware, according to computer security researchers. Ransomware has spread quickly in the last few months, as a number of payouts have attracted cyber-criminals to the technique.

Floods Leave Many Dead in Southern Ghana

Four days of heavy and steady rain has left at least 10 people dead in the south of Ghana. The streets of Accra have been left under water after the torrential downpours caused widespread flooding earlier this week. The nation's capital was hit bit 185mm of rain on Sunday, which is more than they would expect for the entire month of June. This is the wettest month of the year with an average rainfall of 178mm. Since the weekend a further 50mm of rain has fallen exacerbating the severe problems already faced. President John Dramani Mahama has surveyed the areas concerned. He was reported to have driven through several neighbourhoods on a motorcycle. Heavy downpours were also recorded 150km to the west of Accra in the Central Regional capital, Cape Coast where 10 people died in floods,  Sandy Amartey, regional coordinator of the National Disaster Management organisation, told AFP. "In all we have 10 to 12 who lost their lives during this rainy season." The rain...

EC Slaps Apple With £11bn Irish Tax Bill

The European Commission (EC), as expected, has ordered the Irish government to recover up to €13 billion (£11bn) plus interest in “illegal tax benefits”. An investigation found Apple had been able to avoid taxation on almost all profits generated in the EU single market thanks to a structure which routed revenues through two “paper” headquarters in Ireland and minimal tax rates in the country. The EC says Apple only paid an effective corporate tax rate that fell from one percent in 2003 to 0.005 percent in 2014 – a rate which other companies in Ireland were not subjected to. This effectively amounted to state aid, the commission said. Apple tax amazon“Member States cannot give tax benefits to selected companies – this is illegal under EU state aid rules,” said Commissioner Margrethe Vestager, who is in charge of competition policy. “The Commission’s investigation concluded that Ireland granted illegal tax benefits to Apple, which enabled it to pay substantially less tax than ...
