iOS 12 is out, and just days later it is being learnt that WhatsApp won’t work on iOS versions prior to iOS 7.1.2. While the company has not updated its end-of-support blog post since June this year, when it announced iOS 7 and earlier versions will not be supported from February 1, 2020, it has since published a new FAQ section detailing the latest changes to version support. Users on iOS 7.1.2 – the last version of iOS 7 – will also have some limitations to how they can use the app, the company detailed, saying only users on versions iOS 8 and above will have full functionality for now.
To be specific, the Facebook-owned messaging service on its new FAQ section for supported iPhone devices says that “WhatsApp for iPhone requires iOS 8 or later.” It adds that if users have WhatsApp active on devices running iOS 7.1.2, they will be able to use the app until February 1, 2020, however, they will not be able to create new accounts or reverify existing accounts. It reiterates that WhatsApp is not supported on iOS 6 and older versions.
The move won’t affect too many users, except those with devices that received no updates after iOS 7.1.2 – specifically, the iPhone 4, released back in 2010. As WhatsApp explains, these users will no longer be able to add new accounts, or reverify existing accounts, but otherwise, if the app is already active on their device, it will work. The model prior to that, the iPhone 3GS (released back in 2009) didn’t receive an update after iOS 6.1.6 (released in February 2014), and is no longer supported by WhatsApp. The same is the case of the iPhone 3G (released back in 2008) and the original iPhone (released back in 2007). The iPhone 4S (released in 2011), which received iOS 8.4.1 (released in October 2015) as its last update, still retains full functionality, despite being 7 years old. iOS 7.1.2 was released back in July 2014.
iOS 12, the latest version of Apple’s mobile operating system that was released on September 17, is compatible with iPhone 5S (released in 2013) and newer models only. As per Apple’s developer page, where iOS adoption figures were last updated on September 3, 85 percent of active devices are running iOS 11, while 10 percent are running iOS 10, and 5 percent are running older versions. This would imply that while a minority, users running versions earlier than iOS 10 may still number in the millions.
Amazon Echo Input Goes on Sale in India, Brings Alexa to Your Dumb Speaker for Rs. 2,999
Back in September 2018, Amazon added a suite of new products to its Echo line of devices and among them was the Echo Input, which was scheduled to launch in early 2019 in India. It seems as if Amazon has kept good on its promise as the Echo Input is finally on sale in India, at a price of Rs. 2,999. The device adds Alexa support to any of your existing speakers at home, either through a wired or Bluetooth connection. This lets you stream music from Amazon Prime Music, Saavn and TuneIn and starting today, Hungama and Gaana music streaming services too, with simple voice commands. Apart from Amazon, the Echo Input will also be available from offline retailers such as Croma, Vijay Sales and others.
To recall, the Amazon Echo Input was first introduced in September last year, and at around the same time, US-based e-commerce giant had announced it would be made available in India early next year – that time has come. Amazon had not detailed the Amazon Echo Input price in India back in September, and this is the first we’ve learned of it.
Amazon Echo Input launch offers
Amazon has tied up with some speaker manufacturers to bundle the Echo Input with certain products. The JBL Go 2 speaker bundle gets you a flat Rs. 1,499 discount where as you can get the Echo Input for free if you buy the newly launched Ultimate Ears Boom 3 or the Bose SoundLink Revolve. You can check out the offers on right side of the page, just below the ‘Buy Now’ button.
Amazon Echo Input specifications
The Echo Input measures just 12.5mm in thickness and looks a bit like a hockey puck. There are two buttons on the top for switching the microphone off and triggering Alexa, respectively. You also get a four-microphone array on the Input which is said to recognise your voice across a room, even with music playing. There’s a single LED light on the top and a 3.5mm headphone socket and a Micro-USB port on the side for connectivity and power.
It also features dual-band 802.11 Wi-Fiac for connecting the device to you home Wi-Fi. Setting up the Echo Input requires the Alexa app, which is available on both Android and iOS. The Echo Input ships with a 5W power adapter, Micro-USB cable, auxiliary cable and a quick start guide.
Novel technology cleans water using bacteria
Researchers, led by one of Indian-origin, have developed a new technology that can clean water twice as fast as commercially available ultrafiltration membranes, an advance that brings hope for countries like India where clean drinking water is a big issue.
According to a team from the Washington University in St. Louis, more than one in 10 people in the world lack basic drinking water access, and by 2025, half of the world’s population will be living in water-stressed areas.
The team led by Srikanth Singamaneni, Professor at the varsity, developed an ultrafiltration membrane using graphene oxide and bacterial nanocellulose that they found to be highly efficient, long-lasting and environment-friendly.
The membrane technology purifies water while preventing biofouling, or build up of bacteria and other harmful micro-organisms that reduce the flow of water.
For the study, published in the journal Environmental Science and Technology, they used bacteria to build such filtering membranes.
The Gluconacetobacter hansenii bacteria is a sugary substance that forms cellulose nanofibres when in water.
The team then incorporated graphene oxide (GO) flakes into the bacterial nanocellulose while it was growing, essentially trapping GO in the membrane to make it stable and durable.
They exposed the membrane to E. coli bacteria, then shone light on the membrane’s surface.
After being irradiated with light for just three minutes, the E. coli bacteria died. The team determined that the membrane quickly heated to above the 70 degrees Celsius required to deteriorate the cell walls of E. coli bacteria.
While the bacteria are killed, the researchers had a pristine membrane with a high quality of nanocellulose fibres that was able to filter water twice as fast as commercially available ultrafiltration membranes under a high operating pressure.
When they did the same experiment on a membrane made from bacterial nanocellulose without the reduced GO, the E. coli bacteria stayed alive.
While the researchers acknowledge that implementing this process in conventional reverse osmosis systems is taxing, they propose a spiral-wound module system, similar to a roll of towels.
It could be equipped with LEDs or a type of nanogenerator that harnesses mechanical energy from the fluid flow to produce light and heat, which would reduce the overall cost.
If the technique were to be scaled up to a large size, it could benefit many developing countries where clean water is scarce, the researchers noted.
Google loon balloon web service taps board to lift business
Loon, the balloon-borne rural internet service from Google parent Alphabet Inc, has recruited three wireless-industry leaders to help the company’s yearslong effort to get the business off the ground. Wireless pioneer and Nextel Partners Inc co-founder Craig McCaw, former Verizon Communications Inc executive Marni Walden, and Ian Small, a former Telefonica SA executive, will serve as Loon’s new three-member advisory board. They’ll help the fledgeling company sign on partners and expand to new areas.
Loon started as a project inside Google’s X research arm to deliver internet access to rural areas. As of last year, it planned to offer service in Kenya. Using antennas held aloft by large balloons 12 miles (20 kilometres) above Earth, well beyond the paths of aeroplanes, Loon can beam coverage over a wide area and relay the signals to ground stations operated by wireless carriers.
When first conceived, Loon was considered a potential threat to wireless carriers, but in recent years the company has wooed established providers as partners. Other companies including Facebook Inc have been working on ways to get more people connected to the internet. Instead of balloons, Facebook has tested solar-powered drones and satellites.
“We quickly realized that as a business with the mission of connecting people everywhere, our path to success is to partner with those who have significant experience connecting people every day,” Loon Chief Executive Officer Alastair Westgarth said in a blog post.
