When it comes to PCs, having the “best of both worlds” tends to cost more. That’s why you often to see the more bulky and powerful laptops in the same price range as the thin-and-light ultrabooks. They both do well with their intended purpose, but lack key traits that the other possesses.
The most important traits that tend to not overlap are size and performance. But as last generation’s models are starting to be discounted to make room for new Haswell versions, we are seeing prices to drop to new lows and create great bargains. And with the games we’ve seen from Intel and Nvidia — on both the power and efficiency fronts — it is possible now to get serious power and reasonable battery life, all while keeping the machine under an inch thick.
Today’s deal is the Dell XPS 15. This notebook has the power and features of a full-size desktop replacement, with the dimensions of an ultrabook. This wonderful bundle of aluminum, magnesium, glass, and silicon is sturdy, yet light, with a 15-inch display, 0.91-inch thickness and 5.79 lb weight.
Despite the thinness the XPS 15 manages to offer up a 1080p screen, full-power Core i5 (or optional Core i7 quad-core) processor, slot-loading optical drive, backlit keyboard, 65 Whr battery, and Nvidia graphics. It has three USB 3.0 ports — a rarity for an Ivy Bridge laptop — plus dual video outputs (Mini DisplayPort and HDMI), and a card reader.
The model on sale today comes equipped with a Core i5-3230M, 6GB of RAM, 500GB hard drive, and GT 630M graphics for just $899.99, marked down from $1299.99. All models have hefty instant savings attached right now and with the addition of a stackable $100 coupon code we’re seeing the lowest prices ever offered on the premium XPS 15.

The first thing i did after i bought my first laptop was changing it to dual-boot with windows 7 and Ubuntu. I installed Ubuntu 11 10. Now within hours i updated my Ubuntu with few software's likes vlc, shotwell,wine. Later on that week i found few updates for my ubuntu. It had updates for chrome, ffmeg, some updates on system utility too. But when i try to install updates it show up message.I searched few Ubuntu forums and blogs, and found this simple solution. Which i share with my readers below. In Ubuntu panel, click activities > applications> update manager

Look for the settings in bottom of update manager, Click.

On the Software Sources window, click on the Ubuntu Software tab.

Under Downloadable from the Internet, put a check on Source code.

Close the window and the changes will be applied. On Update Manager, click on Install Updates. After checking 'Source code' (which was not checked in my case) The error did not show up again. Hope this works for you too.

Taiwanese integrated circuit producer MediaTek has introduced the world to its eight-core processor, elevating the bar for the competition. MediaTek claimed that all the eight cores of its new octa-core processor run all together unlike existing eight-core solutions available in the market that activate only half of their cores at once. MediaTek didn't name the existing eight-core chips that activate only half of their cores at once, but it might be trying to belittle Samsung's Exynos Octa 5 chip that powers the South Korean electronics giant's Galaxy S4 smartphone. Samsung's Exynos 5 Octa chip, called the Exynos 5420, is based on ARM Mali - T628 MP6 cores. It is powered by four ARM Cortex-A15 cores at 1.8GHz and additional four Cortex-A7 cores at 1.3 GHz in a big-little configuration. The new octa-core chip introduced by MediaTek would make web browsing experience faster and more stable, and also make user interfaces smoother by giving user-inputs to individual cores. In addition, it will render the 3D effects which would pave way for enhanced functionality and appearance of UI in apps as well as operating system. However, the Taiwanese manufacturer didn't disclose the precise specifications and the exact release date for the new eight-core chips.

Canadian smartphone maker, BlackBerry that was formally known as Research in Motion, is offering the second model running the new BlackBerry 10 OS called, BlackBerry Q10. BlackBerry Q10 feature a hardware qwerty keyboard, as traditionally preferred by Balckberry customers and a 3.1in Super AMOLED display with a resolution of 720-x-720-pixels. The BlackBerry Z10, which is the first device to run BB 10 OS, featured a larger 4.2in display. The new BlackBerry Q10 is powered by dual-core 1.5GHz processors and 2GB of RAM. The smartphone comes with 16GB of internal storage that can be expanded to 32GB using a microSD slot provided under the rear cover of the device. As for photography, the smartphone has a 8-megapixel rear camera as well as a 2-megapixel front-facing camera for video conferencing. The new smartphone also has NFC chips allowing users to access new way of file exchanges and support for mobile payments.

The smartphone has curving top and bottom edge and there is a black steel edge around the entire device and a glass front above the keyboard. The back of the device features an impressive gray tweed-over-black pattern.

Review:HTC Butterfly

The Butterfly is the first phone to hit the market with an astounding 1080p display. It also bumps the hardware, with a new quad-core Snapdragon S4 processor, 2GB of RAM and several other improvements. I got a chance to play around with one for a while. Let’s see how it performs.
Design
If there is one thing you can rely on HTC for, it’s to make great looking devices. Their recent phones, especially, have been very good, particularly the One X, the One S and the Windows Phone 8X. Unfortunately, the Butterfly is a bit of an exception. Although not a bad looking phone per se, the design of the Butterfly is quite bland, to say the least. It has none of the charm and charisma of the aforementioned handsets and just comes across as a slim, unremarkable slab of plastic. The only design element worth noticing are the faux-grilles on the sides, and even those are nothing special.

Going around the phone we find the volume rocker placed on the right side, the headphone jack, power button, and the micro-SIM and microSD card together under flap on the top and the microUSB port at the bottom.

On the back of the phone is the camera lens with an LED flash, a secondary notification LED and the loudspeaker near the bottom with the Beats logo.

Ergonomically, the Butterfly is a bit if a mixed bag. On one hand, despite the 5.0-inch display, the Butterfly isn’t much wider than any of the 4.7-inch display phones, which means it is still fairly easy to grip with one hand. The thin body with tapering edges and flat sides also facilitates using the phone singlehandedly.

On the other hand, HTC continues to make life difficult for users by placing the power button directly on top of the phone. The Butterfly may not be much wide but it is very tall and having to reach the button on top is a herculean task that requires constant shifting of the phone in your hand every time you have to operate it, which simply increases the chances of dropping it. Another complaint I have with the design is the use of the annoying flaps for the SIM/SD slot and the USB port. The flap for the car slots is still fine as you don’t have to open it too often but the one for the port is completely unnecessary and annoying considering how often you have to access it. Not only do you have to open and close it every time and then keep it held aside while you plug the cable in, it’s also frustratingly difficult to open. Unless you have a screwdriver or the claws of Wolverine, opening the flap proved to be nearly impossible. One of the reason for the flaps on the ports could be the fact that the Butterfly is water-resistant. This information appears on the company’s website as a single item on the spec sheet and nowhere else does the company boast or even acknowledge it. As such, I refrained from testing the phone under water. The USB port may be closed but there was a gaping headphone jack left open on top that did not inspire much confidence. I briefly mentioned the secondary notification LED on the Butterfly before. It is the first phone that I know of that has not one but two notification LEDs. Unfortunately, it’s easier to spot the Pole star during the day than either of these when they are on, which makes them practically useless. The one on the front is hilariously small and sunken into the earpiece grille, which means when seen at an angle or under bright light it is damn near impossible to see. The one on the back is similarly lame; it’s not bright enough to be seen during the day and its visibility degrades rapidly when you see it an angle. It’s as if the designers thought people hovered directly above their phones at all times or live in a cave to be able to see these properly. In comparison, the notification LEDs on BlackBerry phones can probably be seen from the outer space. The Butterfly is sold in two colors in India: Stealth Black and Glamor White. The former has a matte black finish for the rear whereas the latter has a glossy metallic finish for the back. The white model also has a matte silver strip above the earpiece. The black model looks a bit nicer but the back would pick up scuff marks faster than the glossy white model. Both phones have good build quality and feel fairly sturdy in hand.
Display


The display on the Butterfly is easily the best feature of the phone. The 5.0-inch, 1920 x 1080 resolution Super LCD 3 is an absolute joy to behold. It is the cleanest, sharpest display I’ve ever laid eyes on, all thanks to the insane number of pixels being crammed into that little space. 440 PPI, to be precise. In terms of image quality, the Butterfly does not disappoint. Colors look completely natural, blacks are fairly deep for an LCD and the viewing angles and sunlight legibility are excellent. I had some issues with the contrast, where some of the lighter colors would blend easily with a white background but other than that the display is superb. One thing I would like to point here, though, is that as amazing as having a 1080p display sounds on paper, it doesn’t really make a difference in the real world. Having compared the Butterfly’s display to the One X’s side by side, it was nearly impossible to spot the difference. Of course, the One X does have a brilliant display of its own but it also tells us that 1080p on 5.0-inch or smaller phone screens is an overkill.
Hardware and software
The HTC Butterfly runs on a Qualcomm Snapdragon S4 APQ8064 SoC, with a 1.5GHz quad-core Krait CPU and Adreno 320 GPU. This is one of the fastest chips on the market and also what you’d find under the hood of the Google Nexus 4 and the Sony Xperia Z. On the memory side, it has 2GB of RAM and 16GB internal memory with a microSD card slot. On the software front, the Butterfly runs on Android 4.1.1 Jelly Bean with Sense 4.1. I have never been particularly fond of HTC’s Sense UI and the Butterfly did nothing to change my feelings towards it. Not only do I not like HTC’s still fairly garish visual style, the UI is actually sluggish in several parts, particularly on the homescreen. It also loses out in terms of useful features such as notification screen shortcut icons that you find on Samsung phones. Those who type a lot on their phones would be glad to know that the stock HTC keyboard is still one of the best around, with fairly accurate word prediction and auto-correct. It still has its fair share of idiosyncrasies, however, especially when it comes to typing contractions or symbols. It also can’t automatically add spaces between words if you miss them, which makes typing in a hurry frustrating. So even though it is better than what you get by default on most Android phones, SwiftKey remains the best keyboard to have on Android, for now. In terms of crapware, there was a lot less of it installed on the Butterfly compared to the One X and most of the pre-installed apps such as SoundHound, Dropbox, Twitter, etc. are quite useful.
Performance
The performance of the HTC Butterfly was a bit of a mixed bag. In most cases, the phone performed respectably, with quick app launches and smooth scrolling, as one would expect from a device running Jelly Bean and such a powerful processor. However, the phone would inexplicably stutter when scrolling through homescreens, particularly when you do the pinch gesture to tile the homescreens. I place the blame squarely on Sense UI for this and HTC should really look into optimizing it further as it sours the overall user experience of the device, especially one as expensive as this. The Butterfly comes with the usual Beats branding that has now become common on HTC smartphones. Like the 8X, however, the Butterfly goes beyond just having an equalizer preset and has dedicated amplifiers for the headphone as well as the loudspeaker output. The results of this are quite dramatic. The loudspeaker on the Butterfly is quite loud, especially for a single speaker. The quality isn’t particularly fantastic and it would have been nicer if HTC had tuned the speaker to sound a bit better but at least it’s loud. The headphone output is also similarly loud but it gets even louder once you enable the Beats Audio mode. Along with boosting the volume, Beats Audio also boosts the low as well as the high end of the audio spectrum, making your music sound richer. Of course, this is purely subjective and I personally preferred to keep it switched off most of the times, although it did make certain genres of music sound better. Thanks to the dedicated amplifier, the sound no longer drops whenever you hit a bass note at higher volumes as it used to happen on older HTC phones as the amp has more than enough juice to sustain that level of bass at those volume levels without distorting the sound. As before, Beats Audio setting is universally available for every app installed on the phone and not just the default music player. Unfortunately, if you use the default music player, Beats Audio is all you get, with no option to tune the sound using a custom equalizer or use any other preset. The video player continues to be a disappointment on HTC devices. The format support just isn’t there and even though it might seem as if the phone supports a particular video it would either play it without sound or won’t play it at all. In comparison, the video players on Samsung and LG phones can play pretty much any video file you throw at them without a hitch. Annoyingly, it also lets you choose only between Beats Audio and HTC Enhancer for the sound output. If you watch a lot of videos and movies on your phone, then it’s highly recommended you download a third party video player. When it does manage to play the video, however, viewing them on the gorgeous 1080p display is an absolute joy. It’s also great to finally have a screen where you can watch your 1080p videos with 1:1 pixel mapping (if you have OCD like me you know what I’m talking about). Also, because the display is so dense, even 720p videos look great on it. The general network and radio performance was quite good on the Butterfly. The earpiece is quite loud, so I often had to drop it down a couple of notches during calls. GPS was quick and reliable and the Wi-Fi and Bluetooth performances were respectable.
Camera

The HTC Butterfly has an 8 megapixel BSI CMOS sensor on the back, shooting through a 28mm f/2.0 lens. The phone also uses the ImageSense Chip, a dedicated processor that runs separately from the main SoC and is meant exclusively to process the camera images. For all practically purposes, the camera on the Butterfly is identical to the one on the One X, and it shows in the images. Although the performance is reasonably good, the images still suffer from the overzealous noise-reduction and sharpening. The sharpening, in particular, sticks out like a sore thumb when you zoom 100% into the image. That is also when you’ll notice that the images aren’t as detailed as they should be, the dynamic range isn’t quite good and there is still a fair amount of noise in them.

When it comes to technology, we've been trained to expect more for less. Devices get more powerful each year, as prices stay the same or drop. With the new Nexus 7 tablet, Google hopes we're willing to pay more for more.


The new tablet comes with a $30 price increase over lastyear's model. At $229 for the base model, it is still a bargain - and 30 percent cheaper than Apple's $329 iPad Mini. The display is sharper and the sound is richer than the old model. There's now a rear camera for taking snapshots. The new Nexus 7 is the first device to ship with Android 4.3, which lets you create profiles to limit what your curious and nosy kids can do on your tablet when you're not around.
Amazon.com Inc.'s $199 Kindle Fire HD is cheaper, but it doesn't give you full access to the growing library of Android apps for playing games, checking the weather, tracking flights, reading the news, getting coupons from your favorite stores and more. The Nexus 7 does.
