The Dell XPS 13 is impressive: in a form-factor slightly bigger than the Macbook Air 11”, Dell has managed to provide a powerful 13” thin-and-light platform that scales up to a Core i7 processor, 256GB of SSD storage and 4G as an option. Price At $999, it offers twice the RAM and twice the SSD storage when compared to the current ($999) Macbook Air 11″, and its battery is 50% higher as well (7.5hrs vs 5hrs).
Our base-spec XPS 13 contains a 1.6GHz Intel Core i5-2467M processor with 4GB of RAM and we found it to be more than adequate for general computing tasks, including writing this very review. It was quite snappy and responsive navigating through Windows, playing videos, listening to music and, in general, computing.

This is, again, a 13-inch laptop. While there are multiple choices for processor and disk size there’s but one display on offer, a 1366 x 768 unit that manages to do greater than 720p, but not by much. It is a 16:9 aspect ratio display, so the panel itself is slightly shorter and wider than that on the 13-inch MacBook Air, despite the XPS 13 itself being slightly narrower.

Yes indeed we have some skinny bezels here, but sadly we’re also talking about a screen that has a lower pixel density than the 1600 x 900 panel on the $1,100 UX31. (The Air has a 1440 x 900 display, but you’ll pay $1,299 and up for the privilege.) It’s not a massive difference, but individual pixels are far more noticeable on the Dell.
The webcam of the Dell XPS 13 is pretty decent, and if I compare it to the computers that I have on my desk, it lands somewhere between the Macbook Air 11” (gen1) and the Samsung Series 9 13.3” (2011). It’s a bit difficult to describe the difference in image quality given that none of them are “excellent”, but there’s no question that they all get the job done if you want to hop on a quick family video chat

You’ll find absolutely no surprises under the hood here, as the XPS 13 stays almost exactly in lockstep with the rest of the ultrabook market. Specs include a 1.6GHz Core i5, 128GB SSD hard drive, 4GB of RAM, and a 13.3-inch screen with 1366×768-pixel resolution. The gently tapered chassis features one USB 3.0 port, one chargeable USB 2.0 port, and, oddly, a mini-DisplayPort connector. Landing right at three pounds, it’s an awful lot like a blacker, and slightly smaller, version of the MacBook Air.

Like many Ultrabooks, the XPS 13 certainly turns heads. From the outside, it looks like a smaller version of the Dell XPS 15z and Dell XPS 14z – which is no bad thing. A curvaceous silver aluminium shell clocks in at feather-weight 1.4Kg. While that's lighter than a great many ultraportables, it's not as floaty as some - the Toshiba Z830 weighs in at 1.12kg for example - and there is a sturdiness to it that makes it feel solid.

The backlit keyboard, large touch pad, edge-to-edge Gorilla Glass over the display, and small footprint all add up to an impressive package. If the Dell XPS L322X battery life and screen were better (and the fan were quieter) it could be the best of the current ultrabooks. As it is, it's still in the running, but it's not a blowout win.

The top screen cover is precision cut from a single block of aluminum. This not only makes the XPS 13 look nice but it gives the otherwise vulnerable screen some much needed protection. The sizeable palm rests beneath the keyboard are made of magnesium and covered with soft touch paint. The lower half of the chassis is made of a carbon fiber composite to help keep the weight down and prevent heat transfer from the internal components to your lap.

One disappointment is the screen itself. While the 1,366x768-pixel native resolution is what you'll find in most 13-inch laptops, we've seen 1,600x900-pixel models recently, and the 13-inch MacBook Air has a 1,440x900-pixel display (admittedly starting at $300 more). Edge-to-edge glass is always a look that I like, but the off-axis viewing on this display is poor. Dell is purportedly going to offer a higher-resolution screen in the near future, so hopefully it'll be an improvement.

From a design perspective, the XPS 13 is a fantastic addition to Dell's lineup, establishing a new bar that Dell should aim to clear with its future products. The laptop is attractive, solid, and fast. Dell Studio 1440 battery life is good if you don't go crazy with the screen brightness. Audio is better than you'd expect, and the keyboard and trackpad (after the driver update) don't disappoint. With better display quality, it would be a slam-dunk. Unfortunately, the middling resolution, iffy color reproduction, and poor off-axis viewing leave a considerable stain on what would otherwise be a five-star product. Let's hope that Dell releases a revised version this summer that carries Intel's Ivy Bridge chips and a better display.

Like the rest of the laptops written about here, the Dell XPS 13 is fast to boot, resume from sleep, and a very capable performer. All of the laptops managed my everyday workload, which includes simultaneously writing emails, browsing the web with a number of tabs open, listening to music, and periodically watching video clips.

The built-in speakers are, as you'd expect, less than impressive. They do the job though, and for video conferencing and the occasional YouTube clip are more than adequate.

I wasn't wild about either touchpad; on the Series 9, I had to load a new software driver for it since I wasn't reviewing a final unit. Battery life was disappointing. In my harsh test, in which I cranked brightness to the max, played streaming video in a loop via Wi-Fi and turned off power-saving measures, the XPS lasted just about three hours, the Series 9 about 4½ hours. You can do better under "normal" cicumstances.

The XPS 13 is extremely well built, the keyboard is very comfortable, and it's very thin and light. And for $999, it's certainly a good value for those looking for an attractive and fast Windows 7 laptop. But the aforementioned glaring issues really do hold it back from being the best thin and light laptop on the market. If you want a better trackpad and screen and longer Dell XPS L322X battery life, you'll probably want to have the MacBook Air in that seat pocket, even if it costs $300 more.

The XPS 13 weighs 3 pounds, which is average for Ultrabooks (the HP Folio is currently the heaviest at 3.3 lbs. and the Toshiba Portege Z830 the lightest at 2.5 lbs). It's 0.24" at its thinnest point up front and 0.71" at the rear. The laptop looks like a Dell when it comes to the black keyboard deck and fondness for curves. Happily, the over the top design elements like the shiny spiral hinge and weird speaker grilles found on the XPS 14z and 15z are gone. The lozenge-like aluminum lid is very attractive, though MacBook Air derivative. The tapered sides make for a slim look and feel, and the carbon fiber that covers the bottom and wraps around the sides looks and feels simply wonderful. It's got a soft touch feel, is grippy and has that checkered gray pattern that says carbon fiber (you know what I'm talking about, sportscar geeks).

The maximum energy consumption turns out to be just as inconspicuous, which is estimated to just under 33 Watt at full load. Around half of this should be down to the 17-Watt processor, and other main energy consumers are, for example, the display and the mainboard. We are eager to find out whether the coming Ivy Bridge platform can get more improvements despite identical TDP classifications.

The Dell XPS 13’s aluminium chassis is jaw-droppingly attractive. Outwardly, it’s a smaller, thinner version of the Dell XPS 15z and the Dell XPS 14z – no bad thing. A curving silver shell measuring 7mm at its thinnest point and a barely-there weight of 1.4 means holding the XPS 13 is akin to holding a tablet.

Pentax K-30 announced at May 21, 2012, this is the latest addition to Pentax DSLR camera’s lineup. Another weather-sealed camera that keeps a good balance between features and price. The K-30 is sealed against water splashes, dust and resistant to cold down to -10 Celsius degrees. This is a great camera for the enthusiast outdoor photographer and for people who usually shoot in harsh weather conditions.

This is not a waterproof camera that you can take underwater like Pentax WG point-and-shoot cameras. This is a camera that you might take to you next Ski trip, shoot surfers at the beach, take to a trip to the rain forest, etc.

Pentax already have several high-quality weather-sealed DSLRs, including the K-5 and the K-7. It’s not built with the same Magnesium-alloy body as the K-7 and the K-5, but rather reinforced Polycarbonate over stainless steel chassis, however, it’s still a very strong and durable camera.


The Pentax K-30 is a great camera for novices who want to immediately jump to manipulating a DSLR level camera. In addition to the sensor and Prime M engine, the Pentax K-30 also comes with a state-of-the-art SAFOX Ixi+ autofocus system that enables the sensor to find the sharpest focus under any condition. This is most helpful when covering extreme conditions (and together with the weather seal features of the camera) like during bad weather and extreme hale where there is a blur of activities. Like-wise, it is great for just about anything since pictures generally (note: note always) look better with the subject in good focus.

Aside from a great AF system, the Pentax K-30 also comes with auto pictures modes, which enable the user to find the best possible settings under different circumstances. The creative scene modes number a total of 19 different presets, while there are also an equivalent number of digital filters for one to play around with. Both the Creative Scene Modes and Creative Filters can be combined to create stunning pictures and even create a themed photo slides. In addition, the Pentax K-30 have an SR Mechanism (SR: Shake Reduction) that ensures that the videos taken will have minimal shakiness specially when the cam is handheld, or that pictures taken under low light conditions will have less blur. In tandem with the SR Mechanism, the user can also take advantage of the built-in Automatic Horizon Correction that ensures each shot taken will be leveled out with respect to the ground.

Performance-wise, one can never complain about how snappy the Pentax K-30 is. It starts and shoots at an average of 1.3 seconds in between, and each shutter lag has a very minute almost nonexistent time of 0.1 seconds. Although the camera is tagged at a frame rate of 6 per second, actual measures can go as fast as 5.2 frames per second. Also, it is able to keep the performance running to as much as 63 JPEG shots. As for raw shooting, the camera can take 8 images before slowing down and requires another 5 seconds to write them into the memory card. The autofocus speed is also quick in under good lighting, but slows down to around 0.8 seconds when using Live View. Under dim light, focusing time can take to up to 2 seconds and 4 seconds using the OVF and the Live View respectively. As for the image quality, the sharpness of the pictures is really quite impressive, and detailing is quite good even at the default non-user customized configurations. Video capture is also refined although the K-30 still lags behind other bigger names in terms of focus speeds.

Metering

Pentax is spot on with the metering. During my excursion with the rest of the NYC Press, I did formal Sunny 16 tests and the camera’s meter worked perfectly with the logic.

The Pentax K-30 can record Full HD videos at 1080p at 30/25/24 frames per second. Just in comparison, the Pentax K-7 can shoot only 720p30 and the K-5 can shoot 1080p, but only in 25 fps.

That certainly add extra value to this camera, because when you take this camera in the rain, to the beach or to shoot a Ski event, you can use it for both stills and videos too! – just note that the Pentax K-30 doesn’t come with an external microphone jack, so you need to accept the lower sound quality of the camera’s internal microphone.

Other interesting specs:

6 fps continuous shooting
Shake Reduction (SR) image stabilization mechanism which is useful to 3-stops
LCD comes with anti reflective coating to reduce sun and strong light reflections (needed for outdoor video shooting, but very useful in general)
410 shots battery life (CIPA), not as good as the 980 shots of the K-5 and K-7
ISO 100-25600 (extended)
16.3MP CMOS sensor
PRIME M image processor
Weight: 650g
Dimensions: 130 x 97 x 71 mm (5.12 x 3.82 x 2.8″)
Pentaprism viewfinder: 100% coverage and 0.92x magnification
12m (ISO 100) built-in flash
compatible with SD/SDHX and SDXC memory cards
Shutter speed 1/6000 to 30 seconds
Large variety of scene modes: ortrait, Landscape, Macro, Moving Object, Night Scene Portrait, Sunset, Blue Sky, Forest, Night Scene, Night Scene HDR (JPG), Night Snap, Food, Pet, Kids, Surf & Snow, Backlight Silhouette, Candlelight, Stage Lighting, Museum
6 fps continuous shooting
In-camera HDR
77 Segment Metering system
Rechargeable Li-Ion or AA battery compatible

All in all, the Pentax K-30 looks like an excellent alternative to Canon and Nikon mid-range DSLRs.

Here's the easiest way to block Adult Websites from Children at Home or maybe in the Office.

Did you knew the first website ever made?

Simply put, it was a website made by the World Wide Web’s creator Tim Berners-Lee photo below, who was working for CERN (European Organization for Nuclear Research). The first ever website was published on August 6, 1991 and served up a page explaining the World Wide Web project and giving information on how users could setup a web server and how to create their own websites and web pages, as well as how they could search the web for information. The URL for the first ever page put up on the first ever website was http://info.cern.ch/hypertext/WWW/TheProject.html.

You can easily and effectivily block access to a website by adding it to your Windows HOSTS file.(Yes, Hosts is capitalised for some strange reason). Without any software. Doesn't matter what browser that you use.

Step 1: Click the Start button and select Run. Now type the following text in that Run box:

notepad c:\WINDOWS\system32\drivers\etc\hosts

Step 2: You will see a new notepad window on your screen containing some cryptic information. Don’t panic. Just goto the last line of the file, hit the enter key and type the following:

127.0.0.1 name of the URL you want to block

For example to block the MySpace.com homepage (highly recommended!), simply type:

127.0.0.1 facebook.com
127.0.0.1 myspace.com
127.0.0.1 www.myspace.com

Other parts of MySpace could be blocked in a similar way:

127.0.0.1 search.myspace.com
127.0.0.1 profile.myspace.com
etc etc etc..

You may need to add sites with both with and without the "www.". Test after blocking to make sure you got it right.

You can add as many sites as you wish to block in this fashion. I, myself, have over 12000 undesireable and dangerous sites in my personal HOSTS file!

Step 3: Close Notepad and answer "Yes" when prompted.

Step 4: Reboot your computer and attempt to access your now blocked website. You should see a Cannot find server or DNS Error saying: "The page cannot be displayed"

If you want to remove the ban later, open the same file as mentioned in Step 1 and delete the above lines.

Toshiba rounded-off 2011 year with some of its best TVs in years, and the company has started 2012 in the same vein, with the 46YL863. Staggeringly price considering that it still has features that befit a top-of-the-line set, it seems a steal on the face of it. We see no reason why a TV shouldn't look the part, too; a 46in TV, no matter how slender, is still going to take up a chunk of space. Thankfulle the Toshiba delivers on that front, too-it's just 3cm deep and great for wall-mounting.

Interface and Setup
There are four HDMI connections, two USB inputs, integrated wi-fi plus an ethernet connection, digital audio and headphone outputs and many of the other usual suspects besides. It's DLNA certified for multimedia streaming, too, and you can even turn an external HDD in to a PVR simply by connecting it to one of the USB connections.

The interface uses an intuitive new layout that makes it easy to navigate the huge amount of content and features at your disposal. You'll even find a built-in test pattern fo tweaking the finer details of your picture. Resolution+ aims to improve the sharpness and detail of standard def-content, while Active Vision M800, Toshiba's motion proccessing tech, proves a little unnatural for us in smooth' mode but' standard does make things a little more stable.

The standart selection of analogue and Freeview HD tuners is present and correct, the latter delivering a quality performance. Edges are't quite as robust as the very best, but vivid colours and decent detail ensure were happy what we see on screen. The HD channels ratchet up the quality a notch too, making for a solid off-air introduction.
Did you know?
The Toshiba's CEVO processor is a descendent of the company's older CELL chips, which are used in the PS3 console - so plenty powerful.

CEVO Engine picture proccessor fires up. It works with the new PRO-LED “hybrid” local-dimming LED backlight, which combines both edge-lit and ‘direct’ backlighting to optimise contrast levels. This shows in scenes where the light delivers shadow, the Toshiba doing a good job of applying contrast. And it certainly makes for a punchy image, too with birht colours set against deep black levels. Colours are painted in border strokes here than on other sets, meaning you don't quite get the same level of subtlety, but it's a picture that commands attention with its bold hues.

It's worth noting its adeptness with standard-def DVD pictures, too the picture processing doing a decent job of tidying up edge and presenting clean detailed images. While fast action is largely confidently dealt with, there is on occasion the odd slip this set's grip isn't quite as fast as some. But it's a minor point that's almost moot, like any little gripes with the 46YL863.

The 3D glasses - active-shutter and rechargeable via USB - seem last-gen in style and size, the quality of the 3D TV performance has move forward, in line with rivals, to something that's perfectly watchable.

Toshiba Places is the company's Smart TV offering and very clever. There's a place for video, one or music for social, and this order makes it easy to see what's on offer. The selection is much smaller than its rivals here and doesn't include Skype, Netflix or much catch-up TV, but there's Acetrax for films, BBC iPlayer, Aupeo and iConcerts for music, Facebook and DLNA media streaming.

Toshiba 46YL863 Specification:

Diagonal (cm / inch): 117/46
Resolution: 1920 x 1080
Brightness (cd/m2): 450
Dynamic contrast: 7.000.000:1
Response Time (G to G) ms): 4
Viewing Angle (°): 178

HDMI: 4
3D glasses (the active aperture): Yes
601/709 Colour Selection Decoding: Yes
Energy class: B
Swivel Stand: Yes
Camera (facial recognition): Yes

The 46YL863 includes a huge range of picture adjustment, plus a built-in test pattern to help you manualy adjust things to your taste. You can connect the company's TPA-1 KIT, a USB-based calibrator that works in conjunction with the automated test pattern process built into the set, to configure your picture for you. Set it in the action and results prove decent enough - but you will have to spend thae necessary £200 for the privilege.

The 46YL863 is Toshiba's flagship TV and does the position justice, yet it weights in the best part of 1000 cheaper than rivals' top dogs. It might lack the odd frill, and gives away little here and there in performance, but its's still a massive bargain.

Apple has yet again released a newer version of its acclaimed super thin and light MacBook Air line up. Dubbed as the MacBook Air 2012, this ultraportable device remains at a middle ground between the thicker MacBook Pro and the thinner earlier version, the MacBook Air 2011.

The MacBook Air (mid-2012) battery as lasting “up to 7 hours”, but we’re pleased to report that Apple’s marketing is understating that number by as much as an hour and a half.

Here are various reported samplings from the 2012 MacBook Air 13″:

8:25 – screen at 40% brightness, keyboard backlighting on 50% brightness, light web browsing with Safari (no Flash plug-in installed), and text-based work in TextWrangler and Pages.
6:45 – screen at 70% brightness, otherwise same as above
5:33 – screen at 80% brightness, keyboard backlighting on full brightness, heavy app usage.
4:15 – screen at 100% brightness, keyboard backlighting on full brightness, heavy app usage with tons of apps open including Chrome (with Flash) open with about 25 browser tabs, image editing in Pixelmator, using 6GB of RAM, while driving an external 22″ display.
3:40 – screen at 80% brightness, reasonable app usage, heavy wi-fi usage downloading 16GB sustained at 1.2mb/sec.

The big change in the MacBook Air 13 is the move to the new Ivy Bridge base processor. For the base configuration, this is the Intel Core i5-3427U dual core processor. It offers a slight speed bump over the older Core i5-2557M found in last years model. Performance actually improved much more thanks to the increased speed of the 4GB of DDR3 memory up to the 1600MHz from 1333MHz.

For the 11-inch MacBook Air 2012, the base model with its Intel Core i5 central processor is clocked at 1.7 GHz but has a Turbo Boost capability of up to 2.6 GHz. For the 13 inches, the default processor with its Intel Core i5 chip measures 1.8 GHz but gives up to 2.8 GHz of performance at Turbo Boost. For storage, there are the 64 GB and 128 GB SSDs for the 11-inch model, and 128 GB and 256 GB for the 13-inch model. For the 128 GB in the 11-inch MacBook Air 2012, the drive is configurable with a 256 GB or 512 GB SSD drive. For the 256 GB model in the 13-inch MacBook Air 2012, it can be bumped up to 512 GB for an additional $500. For all versions the default RAM size is 4 GB (1,600MHz DDR3L) with an option to upgrade to 8 GB for another $100.

MacBook Air 2012 Keyboard and Touchpad
The keyboards are just as comfy as ever, and though they're not quite as cushy as what you'll find on a MacBook Pro, they still offer more travel than most Ultrabook keyboards. Also unchanged: that spacious glass trackpad. Throw in the white LED backlighting, and it’s mostly a pleasure to type on. Palm rejection is excellent as well, and we enjoyed flawless tracking in both OS X and Windows 7, which we installed using Bootcamp. The built-in button, too, is quiet and easy to press.

MacBook Air 2012 Screen and Speakers
Apple was ahead of most 13in competitors with the Air’s screen resolution of 1,440 x 900. However, now we’re seeing more and more rivals offering 1,600 x 900 or even Full HD (1,920 x 1,080) at the same screen size. On top of that, while the panel Apple has used is certainly one of the better examples of TN, it’s still inferior to the IPS and PLS we’re beginning to see in premium laptops from other brands.
