iOS 11.2.1 update rolled out with HomeKit vulnerability fix

The new update for iPhones and iPads is about 70MB in size. It focuses on fixing a few bugs, most notably the HomeKit vulnerability that first came to light about a week ago. This bug could potentially let a perpetrator gain access to one’s connected devices like lights, and thermostats among others. With the latest update, Apple has fixed this vulnerability.

The update also fixes an auto-focus issue that cropped up for some users post updating to iOS 11.2. This issue was faced by iPhone 8iPhone 8 Plus, and iPhone X users, Macrumors reports. Users complained about how the camera was unable to focus on a subject. On the dual-camera smartphones, the camera ‘shifted continually between the two lenses’.
To update your iOS device to the latest operating version head over to Settings -> General -> Software Update. It is recommended that you connect your device to Wi-Fi, and a power socket during the update process.
The recently rolled out iOS 11.2 was a major update bringing with it a host of bug fixes, and features like Apple Pay Cash and fast charging. The update however felt rushed, and users have been complaining about issues since day one. But Apple seems to have ironed out most of them, and now’s a good time to update your devices to the latest OS.

Internet economy in South-east Asia to reach $50 billion in 2017: Google report

Southeast Asia’s internet economy, spanning online travel to ride-hailing, will reach $50 billion this year, putting it on a solid trajectory to grow fourfold by 2025, according to a joint research report by Googleand Temasek Holdings Pte.
As more consumers buy airline tickets and book hotels through smartphones, the region’s online travel market expanded from $19.1 billion in 2015 to $26.6 billion in 2017, according to a report the two companies released Tuesday. The research covered four key sectors of the internet economy: travel, media, ride-hailing and e-commerce.
Online shopping and ride-hailing have come into focus as Grab, Uber Technologies Inc and Go-Jek capture consumer preferences with evolving business models. Of the $12 billion of capital invested in Southeast Asian internet companies since 2016, $9 billion was raised by its unicorns, or startups with more than $1 billion valuations. The region, which includes Singapore, Indonesia and Malaysia, raised just $1 billion in 2015.

“This shows how global and regional investors have favored the largest and most established internet companies,” the report said. The growth is being driven by a surging number of new smartphone users. Southeast Asia will have 330 million monthly active internet users by the end of 2017 – equivalent to the size of the US population – after adding more than 70 million users since 2015.

WhatsApp ‘Delete for Everyone’ feature is finally here: Here’s how it works

If you have been sending messages to unintended recipients on WhatsApp and having awkward apology sessions thereafter, this piece of information will cheer you up. After working on the feature for quite some time, the message revoke or delete message for everyone is finally out of beta, and being rolled out to iOS users.
Starting today, WhatsApp is slowly rolling out the Delete for Everyone feature for iOS, Android, and Windows Phone users. As WABetainfo.comnotes, the feature allows you to delete messages in private chats or group conversations. The caveat here is that both the sender and receiver need to be on the latest WhatsApp version.
As is the case with a lot of new WhatsApp features, the Delete for Everyone feature is also being rolled out gradually and you may not immediately get the prompt for the update. The feature applies to text messages, images, videos, GIFs, voice messages, contact cards, files, locations, quoted messages, status replies, and stickers (a new feature expected to be rolled out soon)
How Delete for Everyone feature worksWhen you delete the unintended message, WhatsApp sends a fake copy of the message to the recipient. When the recipient receives that copy, their device won’t show the notification, nor will it save it in his chat history, but it will check if there is the ID of the message in WhatsApp’s database, locate it, and correctly revoke it.
The revoked or recalled messages will also be deleted in the notifications center on iOS. On Android, this message will be replaced with “This message was deleted for everyone”. For quoted messages, WhatsApp is currently not recalling the message that is contained in a quoted reply. Broadcast List also does not support message revoking ability. WhatsApp for Symbian also does not support the feature.
One of the most important things to note here is that you can only use ‘Delete for Everyone’ feature within seven minutes of sending an unintended message. Now this could be a little tricky given how millions of conversations are happening on the platform every minute and in group conversations, it is highly unlikely of members not seeing the unintended message almost as soon as it is sent. Secondly, WhatsApp will not show you the notification for message revoke. On Android, “This message was deleted for everyone” will be the only indication.

The world's first Track-less train that runs on 'virtual railways' begins operating in China

A futuristic rail system featuring track-less trains and virtual lines was launched in a Chinese city of Zhuzhou.
Billed as the world's first 'smart train', the vehicle runs on virtual rail lines through the bustling streets of Zhuzhou in China's Hunan Province, reported People's Daily Online.
The train could travel as quickly as 70kmh, or 43 mph, and carry as many as 300 passengers

Light L16 Camera Uses 16 Lenses to Rival DSLR Quality and Convenience

The L16 camera developed by venture-backed California-based Light recently commenced shipping to pre-order customers. This marks the next phase of the company's plans for a novel optics architecture intended to match or exceed the performance of DSLR cameras, but do so from a more consumer-friendly unit.

The camera's design employs 16 different lenses and optical modules within the one chassis, capturing a scene at several different focal lengths and then applying algorithms specifically developed for the purpose to combine the multiple exposures into a single high-resolution image.

Although only slightly larger than a current smartphone, the L16 is designed to deliver significant improvements in image quality and photographic performance over that currently possible from consumer cameraphones, as well as capturing certain image information that a conventional camera would not gather at all.

"The problem that besets DSLR photography is the bulk of the equipment involved and the need to carry multiple lenses," commented Rajiv Laroia of Light. "Smartphones are much easier to carry, but cannot deliver the same image quality, which is frustrating for photographers using them."
Laroia, whose previous industrial background was in the comms sector for AT&T Bell Labs and Qualcomm before he turned to the optics of photography, designed a solution that would leverage both the recent advances in optical component technology that smartphones have spurred, and some novel systems technology developed for this particular purpose.

Adjustable depth of field

The L16 replaces the bulk and weight of a traditional single-lens camera with several small lenses and sensors, that lie at 45-degree angles across a flat plane. The internal architecture exploits some of the principles behind folded optics to keep the chassis height on a par with that of the smartphones which customers are used to carrying, despite the presence of 16 individual optics units delivering three different focal lengths of 28, 70, and 150 mm.

In use, the L16 intelligently chooses the best combination of the three different focal lengths for each scene, depending on the level of zoom, and adjusts its mirrors to support various fields of view. At least ten of the individual cameras fire simultaneously in each shot, capturing slightly different views of the same scene.
