Karbonn A7

Back and the sides
Another day, another budget Android phone. Google’s operating system seems to have taken off in the Indian region as the market is now flooded with Android devices and it shows no signs of slowing down. Karbonn recently announced its A7 smartphone that aims to pack a whole bunch of goodies in a budget. However, as we’ve seen with previous phones we’ve reviewed, there are certain trade offs that users     are forced to live with. Does the A7 follow that norm, or is it an exception to the rule? Let’s find out.

Nexus 7 review: the best $200 tablet you can buy


___________________________________

DNP Nexus 7 review
In 2008, when the Eee PC was revolutionizing the computing world and driving every manufacturer to make cheaper and smaller laptops, Sony washed its hands of the whole thing. The "race to the bottom," the company said, would profoundly impact the industry, killing profit margins and flooding the market with cheap, terrible machines. Sony was wrong, its stance lasting about a year before joining the competition with its own VAIO W.
Four years on we're buying better laptops than ever before and, with the netbook class now more or less dead, that downward competition seems to have shifted to the tablet front. A flood of cheap, truly awful slates preceded Amazon's Kindle Fire, the $200 tablet from a major brand that looks to have been the proper catalyst in plunging prices. The latest challenger to enter the competition is ASUS, partnering with Google to create the first Nexus tablet, a device that not only will amaze with its MSRP, but with its quality. It's called the Nexus 7, it too is $200, and it's better than Amazon's offering in every way but one.
Hardware
Though that low cost is the big talking point about this tablet, you'd certainly never know it just by holding the thing. Okay, so there's more polycarbonate than panache here, but the design of the Nexus 7 feels reasonably high-end, starting with that rubberized back. Yes, it is rubber, but it's very nicely textured, nice enough to fool one tech journalist into thinking it was leather.

Though the cost is the big talking point about this tablet, you'd certainly never know it just by holding the thing.

No cow shed its skin to cover the back of this tablet, of that we can assure you, but the dimpled pattern here is not unlike the sort you might find on leather-wrapped racecar steering wheels. While there's no MOMO logo to be found, the feel is much the same and, we presume, rather more durable. There are two other logos to be found, though, starting with the Nexus branding embossed in big letters on the top, with a much smaller ASUS graphic on the bottom. That's it, though: understated and sophisticated. Just how we like it. (Even the FCC logo and other noise are on a piece of plastic you can easily peel off.) There's also no camera lens poking out here, as the 1.2-megapixel shooter up front is all you get.
Move further down toward the bottom of the back and you'll find the device's single speaker. It's a slit that runs roughly two-thirds of the way across the back, centered and sitting about a half-inch above the bottom -- which is, by the way, where you'll find the tablet's only ports. Centered down there is a micro-USB connector and, to the far right side when looking at the display, the 3.5mm headphone jack. That's it. Thankfully, ASUS's proprietary connector found on the Transformer tablets doesn't make an appearance here, but neither do we get a dedicated HDMI output, which is a bit of a bummer. (You can, of course, use an MHL adapter if you like.)
Nexus 7 review
On the left edge of the device, similar dock contacts to those found on the Galaxy Nexus can be found, presumably waiting to be tickled by some future accessory, while up top you'll find ... nothing. Just the silvery ring that runs around the full device. It looks like brushed metal, but feels more like plastic. Even so, the tablet has a very sturdy, strong feel to it -- but that's partly thanks to it being just a little bit chunky.
It measures 10.45mm (0.41 inches) thick, which is just half a millimeter thinner than the Kindle Fire -- itself no slender belle. But, crucially, it weighs much less: 340g (12 ounces) versus 413g (14.6 ounces) for the Fire. That's a very noticeable difference and it makes the Nexus 7 much nicer to carry around. Its curved edges, too, make it far more comfortable.
On the inside is an NVIDIA Tegra 3 quad-core processor running at 1.2GHz (though it can step up to 1.3GHz when it wants to) and paired with 1GB of RAM with either eight or 16 gigs of flash storage (doubling the capacity will cost you a $50 premium). As there's no microSD expansion here, you'll probably want to pay the extra cash. WiFi (802.11b/g/n) is your only option for data connectivity, though there's naturally Bluetooth and NFC, not to mention GPS, an accelerometer, a digital compass and a gyroscope, too.
Display and sound
Nexus 7 review
Budget tablets typically make the biggest sacrifices on the display front, and certainly the 1,024 x 600 resolution on the Kindle Fire feels a bit constricting at this point. Not so with the Nexus 7, which is fronted by a very nice 1,280 x 800 IPS panel rated at 400 nits of brightness. While more pixels is always better -- the new iPad and its Retina display having made us yearn for ridiculously high resolutions in all our devices -- WXGA feels perfectly adequate here. Text is rendered very well and 720p videos look great.
Much of that, though, is thanks to the other, less quantifiable aspects of the screen. Viewing angles are top-notch, with contrast staying strong regardless of which side you're coming from. And, it's plenty bright, too, a properly nice screen that, like everything else here, is just a little nicer than you'd expect given the cost.
Audio, however, isn't exactly fighting above its class. The speakers integrated in the back and peeking out through a slender slit toward the bottom deliver a decent amount of sound that isn't too unpleasant to listen to. It passes the "loud enough to fill a hotel room" test but the quality at those levels will leave you reaching for your earbuds.
Performance and battery life
Nexus 7 review
When Jen-Hsun Huang teased Tegra 3-powered tablets would drop under $200 this summer he obviously knew what was coming, but what we didn't know was just how far back those tablets would have to be scaled to make that price point. If you've been reading all the way through to here (and we love you for it) you'll know we haven't yet found a real compromise made to achieve that price. Compromises will not be found in this section, either.
Okay, so a 35-second boot time does leave a little bit to be desired, but once you're inside the OS, applications load quickly and respond briskly, even graphics-heavy ones like the Google Play magazine app. Webpages are rendered promptly and swiping through them is snappy. Sure, there are the occasional stutters and hiccups here that even a coating of Butter doesn't completely eliminate, but we've experienced those with even the top-shelf tablets, like the recent Transformer Pad Infinity TF700with its 1.7GHz version of the Tegra 3 processor.

If benchmarks are to be believed, this little guy actually performs better than its bigger brothers.

In fact, if benchmarks are to be believed, this little guy actually performs better than its bigger brothers. SunSpider tests, which look at JavaScript rendering speeds in the new Chrome browser, were completed on average in a relatively speedy 1,785ms. The tablet burned through Vellamo with an average score of 1,650 and notched 11,713 in CF-Bench. Only the Quadrant score was on the low side compared to the much higher-priced competition, coming in at 3,501.

Since there were plenty of people freaking out about the new iPad getting warm when gaming and doing other intensive tasks we'll point out briefly that the Nexus 7 was noticeably increasing in temperature as these benchmarks cooked away. But, at no point did it become disconcertingly hot. Just a little toasty.

And of course a tablet is only good for as long as you can use the thing, and we were quite impressed by the longevity here. We came within spitting distance of 10 hours on a charge using out standard rundown test, which has the tablet connected on WiFi and looping a video endlessly. That's very, very good for a budget 7-incher and bests many bigger, more expensive slates.
Software
The Nexus 7 is the first device shipping with Android 4.1. We'll defer to our full review of Jelly Bean for full impressions, as it's far too much to get into here, but there are a few aspects of the latest additions to Android that are worth pointing out.
Like those magazine subscriptions we mentioned above, for example. The Play Magazines app is a perfectly respectable reader that has a great selection of content and very smooth performance. While pinch-to-zoom is quite fluid, thanks to the reasonably high-res screen you won't necessarily have to do so as often as you might on the Fire. That's because text is clear and readable if you still have the eyesight to match -- though should you want something a bit easier to parse there's a handy text view.
In terms of pricing, though, we found many magazines to be slightly more expensive here than they are on the Fire. Music, too, tends to cost a dollar or two more per album than what Amazon offers in its MP3 download store. Thankfully, since all that music is DRM-free, there's nothing stopping you from loading up your tablet with what you've bought elsewhere. Nothing, at least, other than the somewhat limited amount of internal storage.

You can finally uninstall that ancient Chrome to Phone plugin.

And then, of course, there's the new stock browser, Chrome. Not a lot has changed since our first impressions a few months ago, so it's still a nice step up from the boring, old Browser app on previous versions of Android. Rendering performance is generally good, and the ability to import open tabs from a desktop browsing session is very handy, indeed. You can finally uninstall that ancient Chrome to Phone plugin.
Wrap-up
Nexus 7 review
The Nexus 7 is an amazing package for something that costs a penny less than $200. It feels like something that could sell for much more. It has a great screen, solid performance and a clean, clear, uncluttered version of Google's latest operating system, Jelly Bean. From a pure hardware standpoint it beats the Kindle in every way possible -- except for content. Amazon's selection almost always trumps that of Google's, both in terms of variety and cost, but that's one wonderful problem to have, because almost all of that content is just as available on the Nexus 7 as it is on the Fire. The only major exception is Amazon Instant Video, and with Netflix, we can live with that.
So, while we tend to prefer larger tablets that better differentiate themselves from phones, if you've been toying with the idea of getting a real Android slate but didn't want to spend big bucks for a big device, this is what you've been waiting for. This is the best Android tablet for less than $200 and the best budget 7-inch tablet on the market. For the moment. The race to the bottom in the tablet space is, after all, just getting started and, if the Nexus 7 is any indication of what's to come, we're in for a very good ride.
Update: We received some bogus information on the MHL. We've now confirmed that the Nexus 7 does not support MHL, meaning there's no way to connect this over HDMI to get video output.

How to Liquify Cigarette Smoke : Liquid Smoke


Smoking itself is injurious to health but lets be honest smoke does look cool. You may also have fancied about those cigarette/hookah smoke rings and other cool things you can do with smoke.

There is this neat little trick by YouTube user “noncents” telling about how to make smoke act like liquid. You would need 1 unfiltered roll up and a cold glass for the trick to work.
He says
Don’t inhale the smoke just pull it into your cheeks and let it fall out your mouth along the inside of the tilted glass. Do not breath as you do this or it will blow it all away!

How to select a WiFi router



If you have a broadband connection a WiFi router is an essential device if you want multiple computers and devices to connect to your internet connection hence a WiFi router is the central hub from where your internet is distributed to all your computer and WiFi devices like Cell Phones / Laptops / Computers so it makes a lot of sense to know a few details about the types of WiFi routers before you purchase a router.
There are a lot of variants you need to look before purchasing a WiFi routers and the features change from model to model, you can get a WiFi router on the low end for just Rs 1,400 to around Rs 11,000 for the high end WiFi routers, as you might have noticed there is quite a price gap and with the more expensive routers you get a lot of additional options and features but it is simply not wise to go for the most expensive router coz you might not need all those additional features.
The basic features that you get with every WiFi router is a couple of Ethernet ports generally 4 so you can connect upto 4 wired computers with the router and WiFi radio which provides WiFi (Wireless internet access) to your WiFi enabled devices like Laptops / smartphones.
Ethernet Speed: Generally in the budget WiFi routers the Ethernet ports provided are of 100Mbps this speed is more than enough for normal usage scenarios but if you daily transfer a lot of data couple of GB’s from one wired computer to another then a router that supports Gigabit Ethernet (1000 Mbps) will help makes the transfers a lot faster also if you have other networking devices like NAS (Network Attached Storage) a Gigabit Ethernet connection helps but again routers that support Gigabit Ethernet connection are much more expensive.

A review by Ranjit.
WiFi Speeds: Most of the WiFi routers sold these days work on the 2.4 Ghz frequency band and support the N band you might get very cheap routers on sale with ‘G’ band which supports speed upto 54 Mbps and the Basic ‘N’ Band router supports speeds upto 150 Mbps these are single band router, you also get routers that can support theoretical speeds upto 300 Mbps do note that these speeds are theoretical speeds and expect real worlds speeds of around 50% of the rated speeds generally for all WiFi connections, as expect a router which supports the 300 Mbps ‘N ‘ speeds has 2 antennas instead of single antenna that we get with ‘N’ 150 Mbps speeds, as expected the price for 300 Mbps ‘N’ router is a little more but in my opinion these routers offer a much better range and throughput than the basic N 150 based routers.
5 Ghz WiFi Band: As stated in the earlier paragraph most of the routers work on the 2.4 Ghz frequency and they offer pretty decent range but the problem with the 2.4 Ghz is that in heavy urban areas particular in apartments, where lot of people might be already using WiFi routers and hence due to that you WiFi routers range might get significantly reduce due to all the interference and lack of clear channel due to other WiFi routers in that area to solve this issue a new band was released on the 5 Ghz, currently the 5 Ghz band is not that congested so if you live a apartment where you are not getting good WiFi reception / range on 2.4 Ghz band you might need to move to the 5 Ghz
WiFi band but do note that you WiFi devices like laptops should support 5 Ghz band and only high end laptops and computers support that also many other devices like mobile phones game consoles etc only support the 2.4 Ghz, taking my personal example in my apartment I see about 8-10 odd WiFi networks and all of them are on the 2.4 Ghz band I have now moved to 5 Ghz band and I am the only one in my apartment that uses the 5 Ghz band hence I have no congestion problems, but do note that the WiFi range on the 5 Ghz band is a bit limited I would say it is about 65% of the range offered by the 2.4 Ghz but if there is a lot of congestion on the 2.4 Ghz band in your area then you might need to move to the 5 Ghz band also the routers that support the 5 Ghz are expensive almost double the cost of 2.4 Ghz band WiFi routers.
Simultaneous Dual Band Routers: As mentioned above we can have WiFi under two bands the standard 2.4 Ghz and 5 GHz some routers to keep the cost down have the option of 2.4 Ghz and 5 Ghz but you can enable only one band at a given time, but there was a need of having both bands works coz many of the older devices do not support the 5 Ghz band for Wifi hence we started to see Dual Band routers these routers can simultaneously transmit WiFi signal on 2.4 Ghz and 5 Ghz at the same time as you can expect dual band routers with gigabit Ethernet connection are one of the most expensive routers in the market.
USB 2.0 Ports: Some of the routers from mid-range also have a USB 2.0 port at the back of the router, and you can attach portable Hard-disk or USB pen drives to the same and store files and access the same from any computer attached to your network so it can act like a Mini NAS device, many of the routers also enable DLNA server for easy media content sharing that is stored on the USB device, so if you have media player like WDTV, PS3 or Xbox 360 you can easily watch movies / media that is stored on that USB device attached to the router.
3G data card support: Some WiFi routers even allow you to add a 3G datacard hence using a single 3G datacard you can get internet access to multiple computers if you router supports the 3G data-card functionality.
Download and Torrent Client: Some of the routers which have the USB port at the back also have a in-built download manager / bit torrent client hence you can download torrents even when you PC is switched off if your router has this functionality.
Guest Network Support: Some of the premium WiFi routers provide an option for adding an additional network with it’s own (SSID) generally called the guest network so if you have a lot of guest you can enable that and give the guest network password to them and they can access the internet but they will not be able to access the other computers on your primary WiFi network, so if you frequently get guest and you do not want them to give access to your primary network look for the guest network feature.
WiFi throughput and overall speeds: It is also very important to note the overall WiFi range offered by the router also it is important to note how the router deals when the load is put on the same for example when multiple computers or WiFi devices are simultaneously connected to the router so do your dude diligence and read up reviews of the specific models of WiFi routers before you purchase one coz not all routers are equal in this regard.
If you plan to use 4-5 Wifi devices simultaneously and a couple of other devices / computers attached to Ethernet port then you might need to purchase a router that has the power to optimally handle the load in these circumstances coz a router is basically a mini computer and budget routers have a low powered processors and little Ram around 8 MB on the other hand some of the high end router have a processor that are in the range of 500-650 Mhz and 64-128 MB Ram hence can handle even heavy loads with multiple simultaneous connections with ease also some routers are friendly with open firmwares like dd-wrt so if you plan to install a third party firmware check if the router supports that.
So these are some of the major things to take into account while purchasing a new WiFi router, if you are looking for a basic router with good functionality then I would suggest the N300 based routers and you can get them below Rs 2,500 but if you require additional functionality the prices of the routers start going up as the feature list get added, I will be doing reviews for some high end Dual band Wifi routers available in the Indian market this month.
