Li-Fi

Li-Fi technology started from the 1990’s in some countries like Germany, Korea, and Japan. “Harald Hass” who is the professor of the University of Edinburgh has found the Li-Fi to transmit the data using visible light in his research.

 What is Li-Fi?

Li-Fi is transmission of data through illumination, sending data through a LED light bulb that varies in intensity faster than the human eye can follow.

German physicist,DR.Harald Haas

Li-Fi stands for LIGHT FIDELITY . It is a wireless communication technology and consider as the new version of Wi-Fi. It uses LED s (Light Emitted Diodes) to transmit the data .

How Li-Fi works?

Every LED bulb can be used like Wi-Fi hot-spots and can sending data through the LED light bulb .If the LED is on , transmit the digital 1’s. If its off you transmit a 0’s. It can be switched ON and OFF very quickly. So its operational procedure is very simple.

Li-Fi and Wi-Fi transmit data through the electromagnetic spectrum. But Li-Fi uses visual light instead of Radio waves to transmit data.

Visible light transmits the information more faster than Radio wave. Researchers said that Li-Fi transmit the data 250 times faster than super fast broadband. And the visible light spectrum is 10,000 times larger than the Radio frequency.

Wi-Fi communication has some issues .Expensive, limited transmission, easy to hack, cannot use it under the water. But Li-Fi gives relief from these issues.

Anyone Create An Online Store From Their Phone

Shopify’s New App Sello Allows Anyone Create An Online Store From Their Phone

E-commerce company Shopify is launching a new app called Sello.

Sello product director Christopher Lobay said that even though Shopify has made it easier for businesses to build online stores, it now wants to go further by “democratizing” the selling process and “removing all the intimidation” that might prevent someone from selling products online.

With Sello, you just snap a photo of the product that you want to sell, add a price and description, then you’re ready to go. You’ll be able to accept credit card and PayPal payments, and you can share your product listings on social networks.

In fact, Lobay said most products will probably be found through social promotion, rather than through the app itself. So Sello is less about product discovery and more about creating those product listings and handling the purchases.

“We think the marketplaces of the future are these social networks and instant messaging and all that stuff,” he said. “Every person has their own footprint, and we allow them to reach out to the community that matters most to them.”

Lobay also described this as Shopify’s first “consumer-facing app.” But it’s not just useful for people selling random stuff — Lobay’s hoping that it encourages people who’ve got a great idea or have built a cool product to actually try selling it. And if they’re successful, then they could eventually move onto larger Shopify platform.

“[Sello] can be for anybody,” he added. “It can be for makers, for people that are selling their own creations, the whole point is it’s for people who have never sold before, it’s their first time. That’s the thread that ties all those people together.”

Sello is available for iOS and Android. It’s a free app and there are no transaction fees (but you will have to pay for payment processing).

Rotten Food Detectors

A startup company called ‘C2Sense’ created an artificial nose-like device, which will detect if perishable food items have gone rotten. The human nose can detect many odors and determine whether food is good or bad -- but not all the time.

This device is essentially a small computer chip. It contains the technology required to determine rotten foods, by recording the level of ethylene gas. This gas is emitted from perishable food items as they begin to turn rotten. When the gas is emitted, it can also reduce the lifespan of any other fruits and vegetables that are close by.

In order to avoid questionable foods, or indulging in awful scents, this device will do it instead. The ultimate goal for C2Sense is to be placed within food packages, which will allow for consumers to conduct their usual shopping with an added sense of health and security.

The website Diffen

Diffen

Here’s a website that lets you compare anything – words, objects, business terms, gadgets and more.

So if you want to know the difference between a turtle and a tortoise; a plasma TV and an LCD TV; AM and FM; epidemic and pandemic, then head to diffen.

You can also browse through categories like health, science, tech, home, food and business to look for common comparisons.

The content for each term is collated and curated by readers, with the main source being Wikipedia.

In case Diffen does not have a readymate comparison table ready for the terms you enter, it will query Wikipedia for an on-the-fly result.

The best part, you can edit its content and add more comparisons to the website.

'NumberSync' AT&T

AT&T becomes the first carrier to link all of your devices to a single phone number

AT&T announced a new service called NumberSync on Wednesday which will allow customers to attach a single phone number to all of their connected devices. Once the service launches, AT&T customers will be able to send and receive messages, make phone calls and more from any phone, tablet or wearable device, all using the same primary number.

The best part about NumberSync is that it doesn't rely on Bluetooth or any other location-based technology in order to provide service to all of your devices. Instead, NumberSync will operate over AT&T's network, which means that even if your main smartphone is turned off or disconnected entirely, you'll still be able to use the service on other devices.

It's also worth noting that there's no additional charge for this service. If you have four connected devices on an AT&T plan, you can give them all the same phone number without paying a penny more than what you're currently paying.

You see only the messages started in Send-not your entire email inbox. But since Send is based on email, you can message anyone with an email address. No additional sign up steps and the people you message can respond from anywhere, even if they don't have the app. This also means the conversation doesn't have to stop when you put down your phone. Send messages are delivered to your email inbox, too. Letting you respond from your computer, when it tickles your fancy.

Windows Dropbox

Dropbox update now lets you Drag and drop URLs 

                             Dropbox update now lets you Drag and drop URLs on the web and PC, view them later on any device. Now, you can drag and drop URLs into your Dropbox - on the web and on your desktop - and open them on any of your devices. This means you can take your bookmarks anywhere, instead of having them confined to a certain browser on a certain computer. But it also means you can organize all your information, no matter the format, into Dropbox folders - so your information is in one central place.

For example, let's say you're planning an event. Your event agency uses Word documents, and your marketing team puts everything in an online company wiki. Instead of checking two (or more) different locations for the information you need, you can put everything in a dedicated Dropbox folder that's shared with the team - so your wiki URLs are next to your Word docs, which are next to the vendor invoices and the invite design mockups - and everyone can have easy access to all the files they need, on all their devices, from that one Dropbox folder.

This feature is also great for students, who can organize and store URLs of academic sources during research - for reading on the go or for future reference when drafting a paper.

What to Do If You Forget Your Android Phone’s PIN, Pattern, or Password

Android normally secures your device by demanding a PIN, pattern, or full password. Your phone isn’t useless if you forget the unlock code — you can bypass it and get back in.

As Google tightens security, this has become more difficult on modern versions of Android. But there’s always a way to make your phone usable again, as long as you remember your Google account’s username and its password.

                                         

Older versions of Android — Android 4.4 KitKat and older — have an integrated way to bypass your pattern, PIN, or other password if you forget it. Google removed this feature in Android 5.0 Lollipop, so you’ll have to use a different method if you have a device with a newer version of Android.

To find this feature, first enter an incorrect pattern or PIN five times at the lock screen. You’ll see a “Forgot pattern,” “forgot PIN,” or “forgot password” button appear. Tap it. You’ll be prompted to enter the username and password of the Google account associated with your Android device.
