Best Windows 8 laptops

Microsoft has fundamentally changed the way Windows works with Windows 8, ensuring it works better with touchscreens and tablets.
But what about Windows 8 laptops, Ultrabooks and convertibles? They're all here, too.
One thing Windows 8 has in spades is convergence. A Windows 8 Ultrabook that has a touchscreen? Check. A laptop with a flip-around screen? Check. Tablet PCs that slide up to reveal a keyboard? Check.
It's tough differentiating some of these from tablets at times, but the one stipulation they have to be in this article is that they have a keyboard and also run x86 Intel or AMD processors. None of the machines in this article are ARM-based.
That means they don't run Windows RT, the version of Windows for ARM systems. They do, however, run either Windows 8 or Windows 8 Pro. Check out our article on the different Windows 8 versions to get your head around which version you'd like.
So here's a rundown of the Windows 8 laptops, notebooks, convertibles and Ultrabooks we've looked at so far, to help you choose the right machine for you. And make sure you read our Windows 8 review, too.

Facebook's Graph Search available to all in U.S.

Watch this video
Facebook's Graph Search, which lets people more efficiently dig through the massive social network for people, places and other content, is now available on all English versions of the website in the U.S.
The advanced search feature will appear as a normal search field at the top of Facebook.com, though it is not yet available to mobile users.
Graph Search raised privacy concerns when it was originally announced, and this wider launch will mean more people can decide for themselves how useful or invasive it really is.
To run a search, type in a full question that lays out what you want to find. Start with the types of content on Facebook such as photos, people, businesses, movies or bands, or a general topic like tea or badminton. Next, narrow it down with qualifiers like location, dates, friend recommendations or profile information.
For example, you can search for "Photos taken in San Francisco, California, of Golden Gate Bridge in 2013" or "Restaurants in Queens, New York, liked by my friends." If you're planning a trip, look for stores or hotels at your destination visited by locals. If you want a date who shares your hobbies, try something like "Single women who live in San Diego, California, and who like pages I like." Then narrow the results using the detailed categories like age, education, home town or religious views.
Once you start typing, Graph Search will helpfully suggest possible combinations and questions.
To protect your privacy and control exactly who sees your information, take a trip back to your Facebook settings and check your sharing options. You can edit the various parts of your profile so that they are only viewable by you or your friends, or if you don't mind meeting strangers interested in a game of tennis, the public.
Under the privacy settings, open up your activity log for granular control of the entire trail of content you've left on Facebook, including likes, groups and events. You can quickly see all photos of you that are visible to the public and change who can see them. Any public photos can show up in Graph Searches based on their location or or the date they were taken. In the main privacy settings view, you can make some bulk privacy settings by limiting old posts so they are only viewable by certain people, or setting the default privacy settings for your future posts.
The company has certain safeguards in place to protect minors from potentially creepy Graph Searches. Profile details for minors are only viewable to their friends and friends of friends, and friends of friends will only see them in searches if they are also under 18 years old.
Facebook says the feature has been improved since it was first launched in January as a beta feature for select users. The company says the latest version is faster, understands natural language questions better, and returns more relevant results.

3D-printed rocket engine gets its first fiery test

(Image: NASA Glenn Research Center)
Thought current 3D printing was only good for creating cute plastic versions of teapot lids, key rings and other curios? Think again. Choreographed high-power lasers or electron beams can fuse and sculpt metal powders into high-performance machine parts. Now NASA has proved that even rocket motors can be made this way.
Engineers led by Tyler Hickman in the Game Changing Technology Programat NASA's Glenn Research Center in Cleveland, Ohio, worked together with rocket-motor maker Aerojet Rocketdyne of Sacramento, California. They wondered if additive layer manufacturing – the engineer's name for 3D printing– could make a precision part called a rocket injector in less time than the year it takes using conventional methods.
Detail are scant because rocket motor designs are covered by US laws that prevent them from being "exported" – revealed to non-Americans. But the result can be seen in the image above. Fed liquid oxygen and gaseous hydrogen, the injector performed perfectly in a series of tests, says Aerojet's programme manager Jeff Haynes.
Better still, it took only four months to make the injector using 3D printing, and costs were cut by 70 per cent.
NASA is not the only organisation trying to take 3D printing into space, however: a public competition is under way to create a crowdsourced design for an open-source, 3D-printable rocket engine that commercial space-flight operators will be able to use.
