Google To Speed Up The Internet With Its New QUIC Protocol

Google is trying every effort to make the World Wide Web faster for Internet users.

The company has announced plans to propose its homemade networking protocol, called Quick UDP Internet Connections (QUIC), to the Internet Engineering Task Force (IETF) in order to make it the next-generation Internet standard.

Probably the term QUIC is new for you, but if you use Google’s Chrome browser then there are chances that you have used this network protocol already.

What is QUIC?

QUIC is a low-latency transport protocol for the modern Internet over UDP, an Internet protocol that is often used for streaming media, gaming and VoIP services.
The search engine giant first unveiled the experimental protocol QUIC and added it to Chrome Canary update in June 2013.
The protocol already included a variety of new features, but the key feature is that QUIC runs a stream multiplexing protocol on top of UDP instead of TCP.

The Idea behind QUIC:

QUIC was developed to speed up latency-sensitive web applications, such as search, by reducing the number of network round-trip time (RTT) that it takes in order to establish a connection to a server.
"The standard way to do secure web browsing involves communicating over TCP + TLS, which requires 2 to 3 round trips with a server to establish a secure connection before the browser can request the actual web page," Google's Chrome team wrote in a blog post.
"QUIC is designed so that if a client has talked to a given server before, it can start sending data without any round trips, which makes web pages load faster."
Here are some QUIC highlights:
  • Packet pacing to reduce packet loss
  • A pluggable congestion control mechanism
  • UDP transport to avoid TCP head-of-line blocking
  • High security similar to Transport Layer Service (TLS)
  • Packet error correction to reduce retransmission latency
  • A connection identifier to reduce reconnections for mobile clients
  • Fast (0-RTT) connectivity similar to TLS Snapstart combined with TCP Fast Open.
Here’s the Big Deal:

With the help of QUIC, Google aims to combine the best features of both UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) with modern security tools with the goal of Zero-RTT connectivity overhead and better SPDY support.

SPDY is a networking protocol introduced by Google in 2009 and is recently being built into upcoming HTTP/2 protocol.
SPDY is also supported by some technologies including Google's own Chrome browser, Mozilla's Firefox, Microsoft's Internet Explorer 11, many websites such as Facebook, and some of the software that delivers Web pages to browsers.
"Today, roughly half of all requests from Chrome to Google servers are served over QUIC and we’re continuing to ramp up QUIC traffic, eventually making it the default transport from Google clients — both Chrome and mobile apps — to Google servers," Chrome team explained.
The search engine giant does not know how much faster QUIC would make Web surfing over the Internet, but ultimately its goal is to bring improvements to the web we are using today.

Best Tools for Copying a Large Number of Files in Windows

If you’ve been using Windows 8 as your main PC, you have probably noticed the vastly upgraded performance and user interface when copying files. Finally, Microsoft decided to revamp some of the core functions of the OS, which makes using Windows 8 so much better than Windows 7…sometimes.
Unfortunately, even with all the great new security and updates to core features, Windows 8 has been hampered by the dual desktop and Start Screen interfaces. I personally switched back to Windows 7 because I find the Start Screen and lack of the Start button frustrating. However, back on Windows 7, I no longer have the new more-reliable copying functions of Windows 8.
In addition to faster performance, Windows 8 also handles file conflicts and other errors way better than previous operating systems. The best part is that you can actually pause and resume copy operations, which is really useful.
copying files windows 8
However, until Microsoft fixes Windows 8 the right way, I’m going to stick with Windows 7 and that means having to use third-party apps for copying large number of files. In this post, I’m going to list some of the best file copying utilities currently out there that you can use for Windows. Depending on your copying needs, some programs are better than others. I can’t say there is one copying program that’s the “best”.
Instead of just listing them out in random order, which doesn’t really help anybody, I’m going to break them down into categories: fastest (local), fastest (network), handling corrupted data, and most features.

Fastest File Copiers (Local)

1. FastCopy 
fast copy
FastCopy has been tested by many people and the results show that it is far the fastest copying program out there for Windows. If you just need raw speed, then this program is the best.
Pros: copies extremely fast, shell integration, x64 capabilities, runs without installation, strong command line support, NSA file wiping utility for secure deleting, handles long path well, ability to see what files/folders will be affected before executing using the listing button.
Cons: Interface is very bare bones and not very intuitive, unable to pause a transfer, uninstalling is not intuitive.
Download FastCopy
2. ExtremeCopy Standard
ExtremeCopy Standard is a free and does a very good job of doing local data transfers really fast. For whatever reason, it’s pretty terrible for network transfers, so don’t bother downloading this program if you have to transfer data across your LAN. It’s faster than TeraCopy and very close to FastCopy.
Pros: copies data fast, integrates directly into Explorer so you can copy and paste like normal, x64-bit version, ability to pause copy operations.
Cons: standard version has no user interface, except for options, bad for network transfers, pro features are available for free in other copying programs, must install program to run.
Download ExtremeCopy Standard
3. KillCopy
KillCopy has a horrific looking interface when you copy files, but it gets the job done very fast. It’s also kind of old and isn’t updated like TeraCopy, UltraCopier and other popular copy programs.
Pros: can resume copy on crash, parallel read/write, resolution options in case of errors or file conflicts, some boost options for faster performance, great network performance when copying, ability to securely wipe data before copying.
Cons:  terrible looking interface, doesn’t get updated very often, must be installed in order to run.
Download KillCopy

Fastest File Copiers (Network)

1. RichCopy 4
This tool was created internally by a Microsoft employee and wasn’t released to the public until years later. It’s a bit old and hasn’t been updated since 2009, but it’s ultra fast for network transfers. However, it’s very slow for local copying, so don’t use this for anything other than network transfers.
Pros: Very fast for network copying, parallel copying, ability to pause and resume copying, ability to continue copying even if network connection lost, clean interface.
Cons: hasn’t been updated in a long time, very slow for local copying.
Download RichCopy 4
2. KillCopy – KillCopy is just a tad slower than RichCopy when performing network transfers. Unfortunately, because of it’s horrible looks and lack of updates, it’s not that popular even though it’s very fast.
3. FastCopy – This is your best bet if you’re looking for one copying program to use on a regular basis. It’s not the fastest for network transfers, but it’s very close and since it’s the fastest for local transfers, it’s probably the best copying utility overall.
4. Ultracopier
UltraCopier is fast, but speed is not it’s main selling point. It’s got a nice interface and has a lot of useful features. Development has slowed down, but it still gets updates every 6 months or so.
Pros: works on Linux and Mac too, supports third-party plugins to extend functionality, start/stop copy, limit speed, search through copy list, simple and clean interface.
Cons: speed is above average, but nothing special.
Download Ultracopier

Copying Corrupted Data

1. Unstoppable Copier
unstoppable copier
This is pretty much the only program that you can use to copy not only a large number of files, but also corrupt files. In terms of copying speed, it’s very slow compared to all the other programs, but that’s because it is the most reliable of all copiers. If you have any data that you believe could be corrupt like data stored on a hard drive with bad sectors or on a scratched CD or DVD, then you should use Unstoppable Copier.
Pros: can recover data from corrupt files while copying, batch mode, various settings for data recovery
Cons: very slow in terms of copying speed
Download Unstoppable Copier

File Copiers – Most Features

1. TeraCopy
If you’re looking for a more full-featured and fancier-looking copier, then TeraCopy is the best choice. It would actually be the best one overall if it’s copying speeds were on par with FastCopy, however, it’s only about average. Where it makes up is all the features and the nice interface.
Pros: very nice interface, integrates fully with Windows, works with Windows 8 x64, stop and start, ability to recover from errors, failed file list, very actively updated.
Cons: copying speed is only average.
Download TeraCopy

Google discontinues Nexus 7, takes it off the Play Store

Google discontinues Nexus 7, takes it off the Play Store

Google’s 2013 edition of the Nexus 7 tablet has been discontinued. You will no longer find it for purchase on the official Google Play Store. The Nexus 7 product page says that, ‘The Nexus 7 is no longer available for purchase’.
As far as tablets go, the Google Play Store is only selling the 16GB and 32GB version of the Nexus 9.
You can still buy off the Nexus 7 on Flipkart at Rs 15,999 for the 32 GB Wifi variant. The 32 GB Wifi ANd LTE  variant is priced at Rs 23,799. You can also find the tablet on sale oneBay and Amazon as well.
Nexus 7 (2013) was also upgraded to the Android 5.0 lolipop last year. This brought in a lot of interesting features on the tablet such as seamless continuity between various Android devices, multiple device compatibility, material design, battery settings and so on. Read our list of 10 key highlights of Android 5.0 to know more.
The 7-inch Nexus tablet sports a 1920 x 1200 pixel resolution and is powered by a 1.5GHz Qualcomm Snapdragon S4 Pro quad-core processor. It has 2GB of RAM.
With this move, it seems like Google wants to ensure more people buy its Nexus 9 tablet which starts from Rs 28,900 on the Play Store. There are no details on whether Google is planning to launch another 7-inch tablet anytime soon.

Lenovo K80 With 4GB of RAM, 4000mAh Battery Launched

Soon after launching the Lenovo A5000 in Russia, the Chinese company has now unveiled yet another smartphone, the K80. Unveiled in China, the Lenovo K80 has been priced at CNY 1,799 (approximately Rs. 18,400) and will be available in the firm's home country starting April 30.

The highlight of the Lenovo K80 smartphone is it features a massive 4GB of RAM and the same variant includes 64GB of built-in storage. The company is likely to place its new handset up against the Asus ZenFone 2's 4GB variant in various markets. Unfortunately, the company hasn't revealed global launch plans for the Lenovo K80.
A standard version of the Lenovo K80 featuring 2GB of RAM and 32GB storage has also been launched at CNY 1499 (approximately Rs. 15,300).
Much like Asus Zenfone 2 series, the Lenovo K80 is also powered by an Intel chipset. It comes with a 64-bit Intel Atom processor (cores, chipset unspecified) clocked at 1.8GHz. It features a 5.5-inch full-HD display. Another notable feature of the Lenovo K80 is its large 4000mAh battery.
The smartphone sports a 13-megapixel rear camera with OIS (optical image stabilisation). There is no word on the front camera on the handset. The Android 5.0 Lollipop-based Lenovo K80 sports an 8.5mm thin body and will be available in black, silver, and red colour options. The launch was first reported by Chinese website CNMO.
On Thursday, Lenovo's new A-series smartphone, the A5000, was launched in  Russia while was also listed on Lenovo's official UAE site without price details. An established retailer the same day claimed the Lenovo A5000 smartphone had been launched in India at 10250/-. Lenovo India is however yet to make an official announcement or list the device on its site.

Acer Liquid X2 With 4000mAh Battery, Triple-SIM Support Launched


Acer on Tuesday launched a new smartphone - the Acer Liquid X2 - but has not yet revealed pricing and availability details.
Showcased during the company's New York press conference, the Acer Liquid X2's claim to fame is its massive 4000mAh battery and its ability to support three SIM cards. Notably, Lenovo this week also unveiled two smartphones with a 4000mAh battery, the Lenovo K80 (which also has 4GB of RAM) and the Lenovo A5000.
The triple-SIM Liquid X2 houses a 5.5-inch display with no word on the display resolution, and is powered by an unknown 64-bit octa-core processor. The handset also includes the same camera on the front and rear - a 13-megapixel offering with a f/1.8 lens.
The firm additionally showcased the Liquid X2's Quick Touch flip case with a vertical slot in between, which gives access to music controls, weather, time and other functions without opening the flip cover. Given the triple-SIM support and 4000mAh battery, Acer says the smartphone is made for those who travel a lot. Not all the specifications are known for the handset, including the Android version it will ship with, but more should be revealed closer to release.
Acer last month also launched its first Windows Phone 8.1 smartphone, the Acer Liquid M220. Acer, which has previously made Windows Phone 7 - powered smartphones, has added that the Liquid M220 will also be upgradeable to the recently announced Windows 10 OS by Microsoft.

Nepal earthquake: Google’s ‘Person finder’ and Facebook’s ‘Safety Check’ helping locate those stranded

Nepal earthquake: Google’s ‘Person finder’ and Facebook’s ‘Safety Check’ helping locate those stranded
At a time when Nepal and parts of India have been convulsed by a devastating earthquake, modern web technology is turning out to be a boon as distressed family members are able to locate their loved ones.
Social networking website Facebook, and Google's Person Finder have helped locate the whereabouts of those stranded in quake-hit areas.
For instance, members of one Himmatramka family residing in Birgunj in Nepal marked themselves safe on Facebook. “Our relatives back in India were worried about our safety. So, we marked ourselves safe to inform them,” said Nitesh Himmatramka.
People from parts of West Bengal and Uttar Pradesh have also used this app mentioning that they are safe.
Facebook's safety tool, ‘Safety App’, is being used to find those in the affected areas. Launched in October last, the app is used to generate alerts to Facebook friends of those trapped in the affected areas who, in turn, confirm that they are safe.

Facebook’s safety check app
“Safety Check is our way of helping our community during natural disasters and gives you an easy and simple way to say you’re safe and check on all your friends and family in one place,” Facebook’s founder Mark Zuckerberg had said in a post.
The idea to launch such an app came after the 2011 Tsunami in Japan, which had caused massive devastation in the country as millions of people had little clue about the whereabouts of their kin for weeks.
Facebook asks the person in affected area to update their safety status thus, generating a notification to friends on the social network about his or her safety, he added.
This feature lets one check the number of people who are safe and those affected by the calamity along with providing information about location where the person is trapped.
Person Finder helps the affected individuals post their safety statuses by using this tool, which acts as a database of missing persons and helps their family members trace them.
It comes with two options–“I’m looking for someone and “I have information about someone”.
The technology gathers information from the families and affected individuals, enabling them to upload information and locate their kin. The technology is available in English and Nepali.
A 7.9-magnitude earthquake jolted Nepal yesterday followed by several aftershocks and left a trail of death and destruction, flattening houses and buildings, including the iconic Dharhara tower and the landmark Darbar Square in the heart of the capital.
Death toll in the quake has climbed to 1,807 while the number of injured has gone up to 4,721.

Sick and Tired of Coughing? These Gadgets Can Help You Dealing With Air Pollution


Air pollution in India is on the rise, and illnesses caused by it have shot up as well. Today, you can look up the air pollution data for your city thanks to the National Air Quality Index and it paints a grim picture. Delhi is one of the most polluted cities in the world, and over 3,000 people reportedly die prematurely every year in Delhi because of high exposure to air pollution.
Dr. Mukesh Tiwari, an ENT specialist based in East Delhi tells us that the number of patients coming with respiratory issues has been steadily increasing, and spiked in the last one year in particular.
"Every second person in my waiting room these days has some difficulty related to pollution, and the only real advice I can give them is - leave Delhi," says Tiwari. Of course, such a drastic step is easier said than done, as Tiwari himself concedes. He suggests taking steps like covering your face when you are commuting, but says that such steps are only stopgap measures.
Google "pollution mask" and you'll find a host of options on various online sellers, ranging from cheap masks which sell for Rs. 250 for a bundle of 50, to expensive ones that cost Rs. 300 per mask.
"You don't need very expensive ones - look for a carbon filter, and buy simple ones," Tiwari recommends.
Buying an air-purifier
While a mask might help you during your commute, it isn't something you can wear all-day, every day. The air in your home meanwhile isn't exactly being filtered out from the outside air, so the problem remains the same. The large particles of dust might not be as prevalent, but the WHO has noted that indoor air pollution is a very serious concern, because of things like drying paint, cleaning products, fumes from your fridge, air conditioner, and more.
Because of this, maybe it's time to consider buying an air purifier for the house. There are a large number of different models available on the market, but do they actually make a difference?
This correspondent has a history of waking up and having great difficulty breathing for the first half hour of each day, so when Philips offered a chance to try out the AC4014 30 watt air purifier for a few days, it seemed like a good idea. After using it for a few days, the difference in the ease of breathing in the mornings was palpable. Could this be psychological? Possibly. But anecdotally at least, many others have reported similar results.

The air purifiers themselves are pretty similar to the water purifiers we're all used to, and which most of us have in our houses. Air purifiers have fans that pull air in and recirculate it through the room. The air is passed through multiple filters to remove dust and suspended particulate matter, and the more expensive ones have something called a HEPA filter. This removes not just dust and mites, but also mold, bacteria and viruses from the air.
The cheapest air purifiers will cost you around Rs. 3,000 to Rs. 5,000, from brands like Kent and Bionaire. These use something called a HEPA-type filter, instead of a HEPA filter, and the difference is important because HEPA is a standard set by the US government.
You can get a Philips 30 watt air purifier at under Rs. 14,000 online and other brands have similar offerings, including relatively high end ones like this one from Blue Airwhich costs Rs. 50,000 and can purify the air in a 240 square foot room. Eureka Forbes - whose Aquaguard is a well-known name in India - also has an air purifier called the Breathe Fresh, available online at just over Rs. 15,000. This 45 watt purifier can be wall mounted as well, and includes a HEPA filter. You can also check out Sharp; it's purifiers are available from retailer stores at just under Rs. 17,000.
When you're buying a purifier, make sure it has a HEPA filter and look at the size of the room it can clear. There's no point in buying a very powerful air purifier if you're using it in a small room - yes, it will clear the room more quickly, but you're supposed to keep it running through the night, so even leave it on if you're at home, so you don't want to waste electricity. Also look at the number of filters that the purifier has - the more the better, obviously. Finally, find out the cost of replacing the filters - you'll be doing this between once in 6 to 18 months, depending on how regularly you use the air purifier.
What else can I do?
Full-fledged air purifiers are pretty expensive, and even if you get one, it will only help cover just one room. Aeroguard - Eureka Forbes' air purifier brand - agrees with us, and a spokesperson demonstrated a lightbulb that also supposedly cleans the air in your room.
The Clean Air Glo costs just under Rs. 1,400 for a 5W LED bulb that can also purify a 10-foot by 10-foot room, according to Eureka Forbes.
We were sceptical, but the spokesperson explained how a bulb can clean air.
"What it does is, releases negative ions into the air," he explained. "These ions go into the air, and impart a negative charge to dust and other suspended particles they touch." The negatively charged dust particles are then drawn towards positively charged surfaces such as walls, or the screen of your television. It turns out that the concept itself isn't very new either, and has been used in hospitals a decade ago.
In fact, while Eureka Forbes might be the first example of putting an ioniser in an LED bulb we found, there are already plenty of other products of this type on the market. This includes expensive American imports that cost Rs. 28,000, but also this one fromKent, priced at Rs. 3,000, or a portable model at just under Rs. 500, which you can plug into your car's cigarette lighter.
The system has some drawbacks. Unlike an air purifier, where the dust is removed and stored in the filter in the device, a negative ion purifier still leaves dust in the room. It's also not as effective as a proper purifier, because it doesn't have a fan to draw air in and circulate clean air.
However, the Eureka Forbes spokesperson points out that the impact can still be significant.
"We run our own tests and third-party testing," he said, "and both show reduction of SPM count in a 100 square foot space, in just 30 minutes. In one hour's time, the particles are almost completely settled."
"This is not a replacement of an air purifier," he added, "but those are expensive. Many people can't buy one, and even if you do, will you buy one for the kitchen, for the bathroom? Those are places where this bulb will be useful."

Micromax Canvas Spark: A Pocket Friendly Smartphone

Ever since Motorola launched the ultra-budget MotoE last year and enticed first-time smartphone buyers, other big brands such as Asus,Lenovo, and Xiaomi have followed suit. While Micromax has had options in that price range for years now, the price-to-performance ratio of those smartphones was skewed. The only exception was the Micromax Canvas A1 - one of the three Android One smartphones made to Google's own standards.
Recently, Micromax launched the Canvas Spark, a phone that costs a little under Rs. 5,000 and runs Android Lollipop out-of-the-box. The Micromax Canvas Spark also has a quad-core processor. Should this be the smartphone any first-time buyer should consider? Let's find out.

Look and feel
Micromax has pulled out  all the stops to create a premium-looking budget device; the Canvas Spark. We received a white/gold unit for review but it is also available in a grey/silver option. The matte rear curves gently, and coupled with the phone's 8.5mm thickness, makes this phone feel really good to hold. Moreover, the weight of 134g is distributed evenly across the entire body. The gold trim running around the edges is actually plastic but Micromax has given it a metallic coating to add some sheen. We saw a similar colour scheme in the Micromax Canvas Gold A300.

A 4.7-inch screen is front and centre. Above it, one can find the earpiece, front camera, and ambient light sensor. Micromax has gone with a row of touch-sensitive capacitive buttons for navigation, placed right below the screen. These Lollipop-style buttons have thin outlines and are not backlit, which makes it very difficult to see them properly.
The volume rocker and power button are on the right edge. The tactile feedback of these buttons is average at best. Machine-drilled holes for the speaker grille are on the bottom of the rear. The camera module on the rear juts slightly out of the main body, thereby potentially exposing it to scratches and also causing the phone to wobble slightly when placed on a flat surface. A thick metallic Micromax logo is placed below the camera. The rear cover is removable but it only reveals the SIM card slots and the microSD card slot; the battery is not accessible.

Specifications and software
Micromax has used the tried-and-tested MediaTek MT6582 SoC on the Canvas Spark. This SoC uses four 1.3GHz processor cores and integrated Mali 400 graphics. The phone also has 1GB of RAM and 8GB of internal storage space. Storage can be expanded by up to 32GB using a microSD card.
The primary camera on the Canvas Spark can capture 8-megapixel still images and shoot 720p video, and there is a 2-megapixel camera on the front. The phone accepts two Micro-SIM cards, of which at least one can connect to a 3G network. Rounding off the other connectivity options are Wi-Fi a/b/g/n and Bluetooth v4.0. A 2000mAh battery powers the device, giving it a rated talk time of 7 hours and rated standby time of 335 hours.

The 4.7-inch IPS screen has a resolution of 540x960, which is similar to that of the Motorola Moto E (Gen 2). However, the screen of the Moto E (Gen 2) is slightly smaller at 4.5 inches and therefore looks a little sharper. The Canvas Spark's screen is average at best with decent viewing angles but below-average sunlight legibility. Thankfully, the display isn't over saturated and the warm colours look pleasant. The screen is protected by Corning's Gorilla Glass 3, which is good.
Micromax hasn't played around much with the stock version of Android Lollipop except for changing the background of the app drawer from white to a slightly transparent dark grey, and the default icons to pastel-coloured flat set. This is actually a great move because the stock Android Lollipop experience is very polished. Micromax has also thrown in a whole ton of third-party apps, most of which won't be useful for most people and cannot be uninstalled.

Performance and camera
We won't mince any words - we faced a lot of performance issues with the Canvas Spark. There were times when an app wouldn't open for a good 15 seconds after we had touched its icon. Also, sometimes the screen wouldn't be responsive after waking the device from standby. Thankfully, these issues didn't completely break the experience but the phone definitely did not feel smooth enough. High-end games struggled with constant stutters, but casual games worked fine. We must highlight the fact that all the Android One phones use the same SoC, but provide a better experience.
In the AnTuTu and Quadrant benchmark tests the phone scored 19,499 and 5,494 points respectively, which are in line with what we achieved with other phones with similar hardware. The Canvas Spark also scored 9.3fps and 3,231 in the GFXbench and 3DMark Ice Storm graphics tests.

We ran our regular set of sample videos and the Canvas Spark only barely managed to play the 1080p files; we faced constant frame drops. The speaker is adequately loud but sound breaks at high volumes. The bundled headset offers decent sound quality but things improved drastically when we used a pair of reference earphones. The sound in phone calls was good and we didn't face any call drops. 
The 2000mAh battery inside the Canvas Spark lasted 7 hours and 16 minutes in our video loop test, which is almost on par with other phones in the same price range. We must add that in daily use we saw the battery life drop drastically whenever we performed any processor-intensive task.
The 8-megapixel camera is clearly no patch on the Infocus M2's, which sells for almost the same price as the Canvas Spark. Our sample images did not have properly defined shadows. A lot of areas, especially those which weren't in focus, were clearly underexposed and colours were slightly oversaturated. The camera app stuttered badly when capturing 720p video (the highest resolution possible on this phone) but the captured footage was fine, apart from some camera shake and the same underexposure issues. Low-light shots were mostly grainy. The front camera also struggled with letting in adequate light.
