The well-known social media Twitter introduces an update to its apps for IOS and Android, which brings a modified focus on direct messaging. The app now features a direct link to Direct Messages in the tab bar and permits the users to send photos inside Direct Messages for the first time.
Twitter was in the testing of new features over the past weeks and those testings are then used to decide which features hit the app itself. There are a variety of new stuff in the latest update, but the photo support feature and enhanced placement of the icon in the right of the task bar showed an enhanced interest in the private messaging portion of Twitter, which has been neglected earlier.
By emphasizing the Direct Messaging feature, Twitter is showing its subtweet towards other messaging apps like WhatsApp, Line, WeChat, etc., The Direct Messaging is hardly used by many users, but some of the changes are said to spur mainstream adoption of Direct Messages as a ‘private comms channel’. The adding up of Messages to the tab bar also knocks Discover from the major view. That’s now inserted under the entire Timelines. Users can now swipe between those timelines in the main view. Timeline, Activity and Discover are all under the single tab now. On one hand, this is a huge space hoarder and senses like a welcome move.
The another update is a filtration option under the Notifications tab that allows users show stuff from just people they follow, all people or just verified people. There are moreover some new notifications to be seen. The ‘blue lines’ update was perceptibly all about that and other changes made to the apps recently reinforce that they are trying to get people to see it as a place where you can talk to anyone and anyone can talk back at any time. They are fighting, somewhat, the perception that Twitter is a spectator sport for most users. This way, if someone takes the plunge and sends a tweet, they get notified of feedback and are encouraged to continue. But, despite all of the other changes, this is quite clearly Twitter’s way of saying that they are interested in being your private messaging client as a great deal as they are your ‘public discussion forum’.
Recently a group of scientists have invented a self-healing battery electrode. The invention is said to be paving the way for next generation of long lasting batteries for cell phones, electric cars and other electronic equipments. The self-healing electrode is made of silicon microparticles that are extensively used in the solar cell and semiconductor industry. The top secret in the rear of the invention is a stretchy polymer that coats the electrode, binds it mutually and spontaneously heals tiny cracks that develop during battery operation, according to Stanford University researchers and colleagues.
Chao Wang, a postdoctoral researcher at Stanford and one of two principal authors of the paper, made the self-healing polymer in the lab of Zhenan Bao, a professor of chemical engineering at Stanford, whose group has been working on flexible electronic skin for use in robots, sensors, prosthetic limbs and other applications. For the battery project, Chao added tiny nanoparticles of carbon to the polymer so it would conduct electricity.
“We found that silicon electrodes lasted 10 times longer when coated with the self-healing polymer, which repaired any cracks within just a few hours,” Bao said. The electrodes worked for about 100ge-discharge cycles without significantly losing their energy storage capacity. “That’s still quite a way the goal of about 500 cycles for cell phones and 3,000 cycles for an electric vehicle,” Yi Cui, an associate professor at Stanford said, “but the promise is there, and all our data it looks it’s working.” Researchers worldwide are racing to find ways to store more energy in the negative electrodes of lithium ion batteries to achieve higher performance while reducing weight.
To make the self-healing coating, scientists deliberately weakened some of the chemical bonds within polymers – long, chain-like molecules with many identical units. The resulting material breaks easily, but the broken ends are chemically drawn to each other and quickly link up again, mimicking the process that allows biological molecules such as DNA to assemble, rearrange and break down. The researchers said they think their approach could work for other electrode materials as well, and they will carry on to refine the technique to improve the silicon electrode’s performance and longevity.
Wearable technologies are now in the forefront of every other technology. Google Glass is the most well-known wearable gadget found yet. As an advancement of this wearable gadget, Vineet Deviah who is the founder of Bangalore based startup Teleportme is now in the work room of a new app for Google Glass.
Devaiah is the man who has received the first Google gleass in Asia. Though he fended off a bid by Google to obtain his company in late 2011, the proffer to build an app to crowdsource landscapes and build an app for Google Glass was too tough to oppose Teliportme has caught a lot of attention, comprising that of Google, because of its app called 360 that permits users to make panoramic pictures on Android phones. The user has to open the app, and pan the phone around as it takes pictures. The app then stitches these images jointly to offer you a landscape sight.
The app also allows the user to share these images. Devaiah’s startup already has a database of 3-4 million images uploaded by users, and the attempt now is too many more users to share panoramas, especially of locations, geo-tag them and provide more details about each. Teliportme will simultaneously build an app for Google Glass that will identify the wearer’s location and match it with the geo-tagged database of panoramic photos in the backend uploaded by users. This will allow the wearer to identify places around him, and even obtain finer details about what he is looking at.
Teliportme’s novel app is different what Google’s fleet of car-mounted Street View cameras capture. “Unlike Street View that ran into regulatory hurdles, the new app crowd-sources images,” said Devaiah, 27, an engineering graduate REC Surathkal in Mangalore. He completed his Master’s in bio-medical engineering at Cornell in the US, got admission for a PhD program at Harvard but decided not to pursue it. “I, initially, met Vineet through a strong reference another investor. I spent some time with him and found him to be very sharp. More importantly, his product had strong traction and he had a strong team with him. We have invested $50,000 in the company,” said Paul Singh, partner in 500 Startups, in an earlier interaction with TOI.
