4 Ways to View Your Laptop or Desktop’s Screen on Your TV

Mirroring your laptop or desktop PC’s display on your TV is actually pretty simple, assuming you know what you’re doing. There are several ways to do this, both wired and wirelessly.
 
The wired methods are the most reliable, although they’ll need an HDMI cable — and possibly an adapter for your computer. Wireless methods can work well, too — they just aren’t perfect.
 
HDMI Cable, Possibly With an Adapter
A standard HDMI cable is still the best way to get a computer’s screen on a TV. This is true whether that computer is a living room PC sitting under the TV, which only outputs to the TV, or if it’s a laptop or desktop with its own build-in monitor mirroring the contents of the primary display to the TV as a secondary screen.
 
This is pretty simple. You probably already have an HDMI cable — if you don’t have one, you can buy a cheap cable like this one and skip the unnecessary expensive cables. Plug one end into an HDMI port on the back of your TV and the other into the HDMI port on your laptop or desktop. Switch the TV to the necessary input and you’re done! You can also use the display options on your laptop or desktop PC to configure how the TV works — whether it mirrors your main display or functions as a secondary desktop.
 
 
That’s the theory. In practice, many modern laptops don’t ship with a built-in HDMI port. Those ports are awfully large and don’t work well with modern, super-thin laptops. You can still connect your laptop to a TV with an HDMI cable, though — you’ll just need the necessary adapter for the port your laptop does include.
 
Many laptops — from Apple’s MacBooks to Microsoft’s Surface Pro convertibles — have a “Mini DisplayPort” port instead of an HDMI port. You’ll need to purchase a Mini DisplayPort to HDMI adapter cable like this cheap one from Amazon to connect that laptop to a TV or other display’s HDMI port. Be sure to check exactly what type of port your laptop has before purchasing such an adapter.
 
Older TVs (or older computers) may not have HDMI support and may require other cables like a DVI or VGA cable. Modern TVs and computers should support HDMI, and you should use that if possible.
 
 
Chromecast Screen Casting   
Google’s inexpensive Chromecast offers an easy way to get your computer’s display onto your TV without any cables. While Chromecast is generally used to “cast” content from a specific app or web page to your TV, you can also cast a specific browser tab. Not only that, but there’s an experimental feature in the Chromecast browser extension that lets you cast your computer’s entire desktop to your Chromecast, viewing it on your TV.
 
How well this works will depend on how powerful the computer is, your Wi-Fi, and other factors. It won’t work as perfectly as an HDMI cable — which just works without any wireless interference issues — but it’s probably the easiest way to do wireless mirroring from any nearby laptop or desktop computer.
 
AirPlay Mirroring
Apple’s homegrown solution requires an Apple TV box hooked up to your TV. After you’ve got the box hooked up, you can use Apple’s AirPlay to wirelessly mirror the contents of a Mac, iPhone, or iPad’s display to your TV.
 
Unlike other wireless display options, this requires you go all-in on a specific device ecosystem — Apple’s. However, if you do have Apple devices along with an Apple TV, this solution will work quite well. Miracast, the open wireless display standard that’s supposed to compete with Apple’s AirPlay, doesn’t work nearly as reliably in our experience.
 

Miracast Wireless Display

Miracast is supposed to be an open alternative to Apple’s AirPlay, allowing you to “cast” an Android or Windows device’s display wirelessly to a TV or set-top box. Support for casting is built into the latest versions of Android, Windows 8, and Windows Phone 8. Your TV may or may not include Miracast, although it’s appearing on more streaming boxes like the Roku 3. We couldn’t get Miracast working with the Roku 3, but you may have more luck. Here’s how to start Miracasting.
Due to all the issues we’ve experienced, we recommend you try Miracast last. If you have hardware that supports Miracast, feel free to try — but don’t go out of your way to buy Miracast-enabled hardware, as there’s a good chance you’ll be disappointed with all the problems you’ll experience. Miracast clearly needs more time in the oven before it can hope to become the easy-to-use, interoperable standard it’s supposed to be.
 
 
There are other ways to get stuff onto your TV, of course. If you’re into PC gaming, you may want to try getting a living room box that can stream games from your gaming PC and display them on your TV. However, you’ll still get better results with a long HDMI cable that connects that gaming PC directly to your TV. When it comes to getting the contents of your computer’s display on your TV, the wired HDMI cable is still king.

How to Check Your Motherboard Model Number on Your Windows PC


Whether you need to update drivers, want to check hardware compatibility, or you’re just curious, it’s way easier to check your motherboard model number with these simple tricks than it is to crack open your computer case to check the board itself. Read on as we show you how to check your motherboard model number from the comfort of your keyboard.

Why Do I Want To Do This?

There are a variety of situations where knowing your motherboard’s model number is important: upgrading your drivers, buying new hardware (you’ll need the proper expansion slots for card-based upgrades and the right memory DIMMS for memory upgrades, etc.), and checking the capabilities of your board if you’re considering upgrading the entire thing.

If you kept the paperwork that came with your computer (or the individual components if you built it yourself) you can often times reference that. Even then, it’s best to check to make sure the documentation is correct. Rather than open the case and search for the model number, it’s easy to use tools within Windows to check things out.

Checking Your Model Number via CMD.exe

If you’re comfortable using the command line, you can easily check a variety of motherboard and hardware stats using the handy Windows Management Instrumentation Command-line (WMIC) a command-line interface for Microsoft’s powerful WMI tool.
With the WMIC we can entry the query baseboard to check motherboard stats and then additional specific query modifiers like get Manufacturer, Model, Name, PartNumber, slotlayout, serialnumber, poweredon to get more detailed information about the motherboard. Let’s check our motherboard’s manufacturer, model number, and serial number using WMIC.
Open up the command prompt in Windows via either the run dialog (WIN+R) or via the search in the start menu; enter cmd.exe into either, no need to run it as an administrator. Enter the following text at the command line.

wmic baseboard get product,Manufacturer,version,serialnumber
This will return the following data.

The above information checks out for our system: the manufacturer is MSI, the board is the Z87-G45 (MS-7821), and while the WMIC tool attempted to check the serial number apparently, alas, MSI left that particular bit unfilled for whatever reason. None the less, the WMIC tool functioned just as it should, and without opening the case or using any third party tools we have the basic information we’re looking for.

How Do I Find All the Pictures Inside a Facebook Chat?



If you usually share photos with friends using Facebook Chat and now you want to find all of them, you could go back to your chat history and find every single image from there. While it is possible to find all of the images using this method, it takes a lot of time. 

Fortunately, Facebook provides a convenient feature that allows you to view all of your shared images in one place. Here is how to access this feature.



For system users:

1.Log in to your Facebook account.


2.On the left sidebar, choose Messages, and then choose the conversation that you want to view.


3.Inside the conversation, click the Actions button, and then choose View Photos in Thread.



4.Now, you can see all of the photos that you and your friend shared inside that conversation.

Eyefi's Wi-Fi-enabled SD cards just got even more convenient

Eyefi just released a new Wi-Fi-enabled SD card called the Mobi Pro. As with other Eyefi cards, the Mobi Pro is a great choice for anyone who needs a way to transfer photos to their PC without wires or the hassle of an SD card reader. Eyefi’s latest addition offers 32GB of onboard storage at class 10 speeds , along with a few clamored-for niceties for photographers on the go.
The new card offers RAW file transfers—an important feature that we’ve seen before but doesn’t come on all Eyefi cards. The new Mobi Pro can also connect to a local Wi-Fi network as opposed to only supporting device-to-device connections.
The final big feature for the Mobi Pro is the ability to selectively sync photos to your PC or mobile phone. Previously, Eyefi cards allowed you to sync everything at once or nothing at all.
The downside of the new Eyefi selective sync is that it’s a serious hack. Any photos you want to single out for sync first have to be marked as write protected on your digital camera. Depending on your camera’s UI, that could be a real pain.
The impact on you at home: The new Mobi Pro is available now for $100, which is a pretty expensive price for 32GB of SD storage. It’s for an extremely fancy SD card of course, and also includes a year’s subscription to Eyefi Cloud—the company’s $50 per year cloud storage service. The Eyefi isn’t an ideal choice for everyone, but if your PC lacks an SD card reader or you want to view your photos on a laptop or tablet while in the field, these cards can come in handy.

How to Hide Files and Folders in Windows Using Command Prompt

Today, privacy is a hot topic. The technique of hiding files and folders comes in handy when you are using a computer which is used by more than one person. This article will show you a techie way to hide files and folders in Windows using command line.
In this post you will learn how to show or hide files and folders in Windows using the command line prompt.
We will use the attrib command to hide or show files or folders in Windows.
attrib: Using the attrib command in Windows, we can change file attributes (i.e., read-only, system and hidden flag).
attrib +h [file/folder name]: This will set hidden attributes to active. It will hide a file/folder.
attrib -h [file/folder name]: This will remove hidden attributes from a file to make files/folders visible to everyone.
How to Hide a File in Windows Using Command Prompt
1. Open your Command Prompt window using the Windows + R key combination, and then type cmd.
2. Navigate to the path where your file is located.
3. Type attrib +h file name to make it hidden.
4. To make it visible again, remove the hidden attribute using attrib -h filename

Ex:

your file in F drive and file name pk.txt

Apple's 12-inch MacBook vs. Windows laptops: Fight!

When Apple’s MacBook Air made its debut in 2008, PC companies were caught flat footed and utterly unprepared for what was arguably a ground-breaking moment in thin computing designs. With the world in financial ruin at the time, it would take years for competitors to catch up.
Apple is headed into a significantly different world with the launch of the radical new 12-inch MacBook, however. If anything, Apple is the one playing catchup with PC makers this time. 
Let's dive into the specs.



The Display

For an Apple ultra-light notebook, one of the most noticeable changes is the high-resolution "Retina" panel. The 12-inch display features an odd-duck resolution of 2304x1440 with an aspect ratio of 16:10. That's a big leap for Apple, especially coming from a MacBook Air lineup that still features 1440x900 panels at best and embarrassing netbook-like resolution panels of 1366x768 at worst. 

The new Retina display in the MacBook is welcome but it's easily surpassed in pixel density by such notebooks as this Lenovo Yoga 3 Pro.

Also in the good news column, the MacBook's panel is an IPS versus the TN in the two current MBAs. I know some professional photographers who don't even bother to use MacBook Airs for color critical work because of the low resolution and lack of color accuracy in their displays. Apple also said the panel it selected uses more efficient and smaller transistors, so it uses 30 percent less power at the same brightness levels as its existing products.
The unique resolution tells me Apple likely had it custom designed and built to specs. Most PC vendors like to stick to standard aspect ratios to leverage the scale in prices. Since Apple will probably sell a killzillion MacBooks over the years, it probably doesn't have to worry about it quite as much.
It's not yet known yet, but it sounds like Apple's panel could be an IGZO panel. IGZO panels are more efficient at transmitting light than a typical IPS panel so you don't have to drive the backlighting as hard for the same brightness. 
Image quality, brightness, and the display's performance, can't be judged yet, but on pure specsmanship, the MacBook's display is a me-too move.
Again, it's not clear to me why Apple picked a resolution of 2304x1440 for the new MacBook Air 12--perhaps to balance power consumption?--but that works out to a PPI of 226 and a pixel count of 3.3 megapixels. In the PC world, that's just average. The 13.3-inch Dell XPS13 has an option for a 3200x1800 panel with a PPI of 276 and a pixel count of 5.7 million. Similar-resolution panels are abundant in the PC world, too. The Lenovo Yoga 3 Pro also hits the same resolution as the Dell. Plenty of other notebooks and convertibles come close or supercede the resolution as well.
Like I said: On pure specsmanship, the 12-inch MacBook gets a big meh here. Apple fans, however, should cheer that they're finally able to get a high-res display in a thin-and-light laptop. 
 

The form factor

Apple makes much hay about the size and weight of the new MacBook. It's basically 11 inches wide by 7.74 inches deep, with a maximum height of 13mm. (This, by the way, is how you crash Mars space probes: mixing standard and metric measurements.) Not bad.

The Yoga 3 Pro is 12.7mm thick vs. the 13mm of the new Apple 12-inch MacBook
I measured the thickest part of the Dell XPS13 at 18mm and the current MacBook Air 11 at 16.8mm (Apple's specs actually say 17mm at the thickest part). The XPS13 probably isn't the best representative though. The Asus Zenbook UX305 is about the same thickness as the 12-inch MacBook at 13mm. The Acer Aspire S7 and Lenova Yoga 3 Pro are a smidge thinner at 12.7mm.
The new MacBook also sports an impressive 2 lb. weight. That shaves about half a pound off most PC laptops. The Dell XPS13 and Yoga 3 Pro are about 2.6 lbs, as is the Asus Zenbook UX305. That makes the new 12-inch MacBook Air pretty light—just not the lightest.
That title will likely belong to Lenovo when it ships its LaVie HZ550 later this May. Using an IGZO panel and a magnesium lithium chassis Lenovo has cut the laptop's weight down to 1.72 lbs.. I hefted one at CES and thought it had been pumped full of helium. To be fair, though, the pre-production LaVie I tried didn't have the greatest keyboard and it wasn't super thin, at 16.9mm. 

Performance

The Core M in the new 12-inch MacBook is no Atom, but it can't hang with faster (and hotter) Core i5 and Core i7 like this XPS13.
The new MacBook packs a fanless design using Intel's Broadwell-based Core M chips. There's an option for the 1.1GHz Core M, which I'm assuming is the either the Core M 5Y51 or 5M 5Y70, or the 1.2GHz Core M 5Y71. I've gone ahead and lined up the three potential chips over at Intel's ARK if you want to dive into the specs.
Core M chips are essentially low-power Broadwell chips that generate about a third of the heat of the Broadwell U processors used in many recent PCs. This lets vendors build truly fanless systems.
Losing the fan and living on a third of the thermals does significantly impact performance though. In Asus Zenbook UX305, I saw roughly a 25 percent performance hit over the XPS13 with a Core i5 5200U in it. The hit in graphics performance is far worse. 
What's important here though is the design of the new MacBook. I've seen three Core M laptops, and so far, the performance is all over the map. It seems that either you let the skin temperature of the laptop get toasty and maintain good performance or you keep it cool and take a performance hit.
Don't take this too negatively, though. Core M is no Atom (although I have seen some numbers dip to the point where a desktop Atom can defeat it). For most of the tasks people use ultra portable laptops for, you won't be able to tell it from a Core i5 or Core i7 CPU.
For a final judgement on cross-platform performance we'll have to wait to get a new MacBook. The real sticky question: Is it even fair to a fanless notebook against one that's actively cooled? My gut says the Dell XPS13 will easily be all over the 12-inch MacBook from a performance perspective. But it has a fan that makes its presence known.

Battery life and capacity

Apple's terraced lithium polymer cells let it stuff as much battery as possible into the new 12-inch MacBook.
One of the 12-inch MacBook's more unique touches is its batteries, which Apple claims to have built up in layers. Terracing the battery packs lets the company jam the maximum physical amount of battery capacity into the shell.
By the raw numbers, it seems to have worked. The 11-inch MacBook Air has a 38 watt hour cell in it. The much thinner and lighter 12-inch MacBook has 39.7 watt hour cell. Combined with the Core M chip, Apple claims it'll give you 9 hours of browsing and 10 hours of iTunes movies. (Who really uses iTunes to watch movies?). That's the same browsing rating as the MacBook Air 11, and the one hour more in movie playback. You may say meh, but remember: The new MacBook packs a significant increase in resolution.
The original MacBook Air essentially has a 1 megapixel display at 1366x768. The new MacBook basically has triple its pixel count, yet slightly more battery life.
What about compared to PCs? Well, that's not easy to do, and if you do, people will just choose to disagree. I can say that in run time, PC's can hang—but everyone's mileage will vary depending on what he or she does.  
But you still want to know what PC's are powered by so I'll tell you: The Zenbook UX305 packs in a 45 watt hour battery while the XPS13 is running a 52 watt hour job. HP's new Spectre x360 runs a 56 watt hour cell.

Ports

Up is down and white is black. Apple says one USB Type C is an improvement while most people complain about the lack of ports today.
Now onto the most controversial decision Apple made with the new MacBook. There's but a single USB 3.1 Type-C reversible USB connector on the laptop, along with a combo analog audio port. There's no HDMI, no Ethernet, no SD card slot--nothing else whatsoever. Maybe this is my personal bias but give Apple credit for taking what would be seen as a limitation on a PC and turning it into a strength:
"Only one USB port and HDMI port on this ultrabook?! You suck, vendor X."
"Only one USB port that's not common at all on this new 12-inch MacBook? Wahoo! Apple does it again!"
I'm not sure who is actually asking for a reduction in ports on his or her laptops but I prefer more ports rather than fewer--especially common ports. Not having at least one standard Type-A USB port on the laptop itself is a weakness. Sure, there's a dongle adapter to make the Type-C connection play nice, but if you lose that adapter, you're not going to copy a file from a USB drive to your laptop. 
Ask any IT department that issues Macs about lost dongles.
Despite Lenovo's Yoga 3 Pro being thinner than the 12-MacBook at 12.7mm on paper (although I measured it just a tad thicker) has two Type-A USB ports, analog audio, a microHDMI connection, and an SD card reader on its side.

Keyboard and trackpad

Apple says it designed a new butterfly switch to make the keys larger and more stable while also making them thinner.
Here's an area where Apple looks to have an early advantage over PC vendors. The company said it designed a "butterfly" switch for the MacBook's keyboard instead of using the standard scissor keyboard switch that's been used on laptops for the last two decades. Apple says the switch is more stable and thinner and allows for larger keycaps.
These are all good things and I suspect it's an area PC vendors may have to work hard to catch up. But then, PCWorld's resident keyboard expert Hayden Dingman points out there have been plenty of variations of scissor switches over the years. Razer, for example, has been playing with laptop switch designs and designed two different types of switches for its Razer Blade and Razer Blade Pro. No matter how good a laptop keyboard gets, it'll never be a mechanical keyboard.
The trackpad may also be a competitive advantage for Apple with its feedback system. It's also pressure sensitive, but that's not really new. Synaptic's ForcePad, for example, is one of the trackpads that have been available on PCs for years.
Still, this is one area Apple usually brings its A-game, and PC vendors will likely have to find a way to respond if people report the MacBook's keyboard knocks it out of the ballpark.

Price

The new MacBook is $1,300 with a 1.1GHz dual-core processor and a 256GB SSD, or $1,600 to go to 1.2GHz dual-core processor and a 512GB SSD. All models feature the same 12-inch high-resolution panel and 8GB of DDR3L/1600 RAM.

Apple will have no price edge compared to notebooks like this Asus Zenbook UX305 with its fanless Core M, 256GB SSD and 8GB of RAM for $700.
What does those prices get you in the PC world? Asus Zenbook UX305 with its Core M, 8GB of RAM and 256GB SSD: $699. The Dell XPS13 with 3200x1800 touch screen, 8GB of RAM, 128GB SSD, and more capable Core i5 processor is $1,300. HP's new Spectre X360 with a hulking, Core i7, 8GB of RAM, 256GB SSD, and 1920x1080 screen is $1,150.

Conclusion

Unlike in 2008, the 12-inch MacBook won't be flying into unclaimed territories when it goes on sale in April. Instead, there will already be companies there camped out with laptops that are cheaper and--on paper at least--better.
That said, the new MacBook does seem to hit a lot of the high points that people want: A good keyboard, a good trackpad, a higher resolution screen while maintaining good battery life, and weighing near nothing. It'll be interesting to see how Apple's newcomer stacks up when it hits the real-world streets.

What happens when a hard drive crashes

Hard disk head crash
 
When my friend took his dead PC to a repair shop, he was told that the hard drive crashed. He asked me what physically happens to a drive to crash it.
 
Hard drives, unlike the SSDs slowly replacing them, are mechanical machines with moving parts. Each drive has one or more spinning platters, extremely tiny magnetic read/write heads, two motors, and a fair amount of circuitry. When working properly, one motor spins the platters at a very fast speed—usually 5400rpm or 7200rpm. The other motor moves the read/write head in and out with microscopic precision. The head doesn’t come into physical contact with the platter, but it floats on a cushion of air that may be as little as five nanometers. That’s less than 0.0000002 inch. It’s a wonder they work at all.
 
Today, we describe a drive as having crashed if it suddenly stops working—no matter what caused its death. But the word originally comes from one particular problem: A head crash.
 
That’s when the drive’s read/write head comes into physical contact with the platter—the microscopic equivalent of an airplane hitting the ground so hard that it scrapes the asphalt off the runway. In a head crash, the head scrapes off the magnetic coding containing your data. Whatever files were on that part of the platter are history.
 
But there are other, less spectacular mechanical crashes. If the head alignment goes off by just a few nanometers, the drive could become unusable. In this case, however, it’s possible for a skilled technician with the right equipment to recover your files.
 
Either type of crash can be caused by a sudden impact, such as dropping the drive. If the drive is powered up and running, even a slight move can cause damage. But even if your drive never suffers anything cataclysmic, general wear and tear can eventually crash it.
 
Not all crashes are mechanical. The circuitry can also wear out over time, especially if your PC frequently overheats.
Here are a few tips to help you avoid or survive crashes:
  1. Handle a hard drive, or a laptop containing one, carefully.
  2. Avoid moving a PC containing a hard drive unless the PC is off or in sleep mode.
  3. Protect your PC from overheating.
  4. Back up daily. 

Robots to get more processing muscle with Intel's Xeon D chips

Intel’s Xeon server chips dominate hardware in data centers, and now they could also end up powering robots on factory floors.
 
The new line of Xeon D chips, announced Monday, are designed primarily for servers and network appliances, but as industrial automation grows, Intel believes the chips can all add processing muscle to robots that handle complex manufacturing tasks.
 
Simple robots that do mundane work can run on basic, low-power processors, but faster chips are being plugged into advanced robots for more sophisticated tasks.
 
Xeon D is the first server chip from Intel based on the Broadwell architecture. It’s already being used in PC chips, but it’s graduating to servers, appliances, and now perhaps robots.
 
The chip has features that could benefit robots, such as on-chip security to protect them from hackers. It also has high-reliability features that are increasingly in demand where failure isn’t an option, said Dean McCarron, principal analyst at Mercury Research.
 

Assembly line tools

An example is optical inspection, used for quality control in manufacturing and packaging. Objects are scanned and compared against a database, and flagged if a unit looks defective or doesn’t match patterns.
 
“Throwing more compute power gives you more options,” McCarron said. “With the compute power comes fancier algorithms and more advanced ways of doing the job.”
 
Xeon D will let robots to execute Internet of Things tasks by letting them connect to cloud services for information and giving them stronger on-board processing to parse and analyze data.
 
Intel said Xeon D can be customized and made available in power efficient designs, which means special chips can be developed for robots. But the first chips in the lineup, the quad-core 1520 and eight-core 1540, are targeted at micro servers and networking appliances.
 
Intel already sells low-power chips called Xeon E3 and Atom chips code-named Avoton. But Xeon D will provide more horsepower while being relatively conservative on power consumption. The dense servers and appliances will be used for web hosting and cloud services, and for processing data generated by the growing number of mobile and sensor devices, said Raejeanne Skillern, general manager for cloud services at Intel’s Data Center Group.
 
An estimated 50 billion devices will be transmitting information by 2020, and the emergence of the Internet of Things highlights the need of power-efficient servers and edge appliances that can deliver information and scale performance quickly, Skillern said.
 
Xeon D is effectively a system-on-chip, with a combination of components including I/O and controllers for networking and storage appliances. Intel was due to ship the Xeon D chips by late 2014, but had to shift dates following manufacturing glitches affecting Broadwell processors.
 
The Xeon D will draw a minimum of 20 watts—higher than Avoton’s 15 watts. An eight-core Xeon D chip was 3.4 times faster in Web serving than an eight-core Avoton, 2.5 times faster in storage, and around 3.1 times faster in networking, according to Intel’s internal benchmarks. The tests were carried in Hewlett-Packard’s Moonshot and Supermicro’s Superserver dense servers.
 
Per watt of power, users will get 70 percent more performance with Xeon D compared to Avoton, Intel claims.
 
There may be some overlap between Atom workloads and Xeon D workloads, but Intel wants to provide a wider range of options for performance, density and cost, said Lisa Spelman, director of datacenter product marketing at Intel’s Data Center Group.
 
The Xeon D improvements will support 128GB of DDR3 and DDR4 memory, 10GB ethernet and PCI-Express 3.0.
 
Intel has also said it offers reprogrammable FPGA circuits with Xeon D chips, but the company will share more details about those options in the second half of the year.

How to automatically switch default printers based on your location

Managing printers can be a pain especially if you're shifting a laptop between home and work and dealing with different printers on each network. Fortunately, Windows has a built-in tool just for you that lets you automatically switch between default printers based on the Wi-Fi network you're connected to.
 
If you have a Hewlett-Packard printer at home and a Canon at work, for example, Windows would automatically send print jobs to the Canon whenever your laptop was on the work network.
 
The beauty of this feature is you only have to set it up once and never think about which printer is where again.
This tip should work for all users on Windows 8.1, but Windows 7 users will only have this option available to them if they are running Windows 7 Professional, Ultimate, or Enterprise.

Defaulting printers
windows lets you switch between default
printers based on location
Open the Control Panel, go to Devices and Printers and then scroll down to the Printers section. There you'll see a list of all the printers your PC is familiar with. At least one of them should have a green check mark next to it, which is your default printer.
 
Click any printer you want to set as a default at a given location, then click Manage default printers at the top of the Control Panel window.
In the new window that opens, make sure the Change my default printer when I change networks radio button is selected.
 
Below that you'll see two drop down menus and a list of printers that are already selected as your defaults. To add a new default printer, select a Wi-Fi network from the first drop down menu and a printer from the second.
 
In the example above, I'm making Google Cloud Printer the default when I'm on my Mother's network. Next, click Add and you're done.
 
If you use printers in more than just two locations, add those as well—you'll never have to think about which printer you're sending to again.

3 Questions to ask before buying a tablet

Light, stylish and delightfully easy to use, it's no wonder that tablets have become so popular. A few years ago there were only a handful of models but in today's market, there are a lot more to choose from. So how do you find the right one for your needs? Here are 3 simple questions get you started.
 What size best suits you?
Tablets generally come in 3 sizes: Small (7 – 8.3"), Medium (8.9 – 10.1") and Large (10.1" and up). Each has it own advantages and preferred uses so picking the right size really depends what you need your tablet for.
If you’re looking for something light and compact for reading e-books, a small tablet will be ideal.
Medium-sized tablets are generally a good choice for games, reading magazines or watching movies.
A large-sized tablet is more frequently found as the detachable screen of a hybrid (2 in 1) laptop. They may cost more but the larger screen is more productive for getting work done,especially when used with a keyboard.
      Will you be using it more for entertainment or work?

If you want a tablet mostly for games and entertainment, an Android*-based one may be a good choice as there is a wide variety of apps available.
For work, a Windows* powered tablet may be a smart choice because of the compatibility of software like Microsoft Office with your office laptop or desktop.
If you really need something to get down to business, consider a 2 in 1 or hybrid laptop that combines the responsiveness of a tablet and power of a full-size laptop in a convenient little device that's a joy to use.

    How much are you looking to spend?
The variety of tablets available means a broad price range, making it possible for anyone to find a price point that seems him or her.
Shopping on a budget? Value tablets are affordable and still pack enough performance to do the basics like surfing the Internet and reading e-books. But if you run more demanding apps like games, performance may be an important consideration.
Premium tablets may cost more, and the price may be due to the incredible app support, quality build materials or fast performance1. This means it looks amazing, feels great and performs brilliantly for games, videos and even work1.
 
Once you've figured out what size you prefer, what you need your tablet for and how much you're willing to spend, you're well on your way to buying your first tablet. To get you started, check out some of the latest tablets on the market powered by Intel.

Google confirms poor performance is to blame for reneged Android Lollipop encryption pledge

It turns out there was something to the report that hardware performance was to blame for Google backing off its encryption requirement for new Lollipop devices.
 
Google issued a statement to Engadget, confirming that many phones won’t come with encryption turned on, a reversal of the company’s original plans:
 
“In September, we announced that all new Android Lollipop devices would be encrypted by default. Due to performance issues on some Android partner devices we are not yet at encryption by default on every new Lollipop device. That said, our new Nexus devices are encrypted by default and Android users (Jelly Bean and above) have the option to encrypt the data on their devices in Settings —-> Security —- >Encryption. We remain firmly committed to encryption because it helps keep users safe and secure on the web.”
 
Such problems started showing up as early as November, when a test showed flipping on encryption tanked Nexus 6 storage performance. This issue has clearly hit enough Android devices to compel Google to back off from its original plan to require encryption in all new phones running Lollipop.
Fortunately, you can turn this security feature on yourself by following our encryption guide
 
Why this matters: Encryption-by-default is long overdue for Android devices. When it’s upgrade time, you’re likely to sell off or trade in your phone, meaning someone else will be using your old device. If your data isn’t encrypted, someone with nefarious motives could possibly gain access to your old stuff.
