Lego is something that is most often used to build models. The versatile little bricks have been keeping children (and adults) entertained for generations, and there have also been plenty of instances of the toy being used for more than just playing. Now, thanks to the work of designer Carlos Arturo Torres, children with a missing limb could build their own from Lego.

It's an idea that merges the worlds of play and entertainment with practicality. The Colombian designer has come up with a modular system which can be used by inventive kids to create elaborate arms that are as functional, as advanced, or as silly as they want.

Apple is letting developers and enthusiasts test out beta versions of iOS 9 ahead of launch. While the company is keen on getting feedback for the next version of its mobile operating system (just as Microsoft is with the preview builds of Windows 10), there have been concerns that problems with apps during beta testing has led to a swathe of negative reviews in the App Store.

Microsoft has revealed its financial results for Q4 FY 2015, posting its biggest-ever loss thanks to a $7.5 billion write-off related to the acquisition of Nokia's Devices & Services business. In the second quarter of the year, Microsoft's revenue was $22.2 billion, while gross margin, operating loss and loss per share came in at $14.7 billion, $2.1 billion and $0.40 per share.

Microsoft has also revealed a $780 million "restructuring charge" as well as a $160 million write-off that is related to its previous restructuring plan. However, both are basically chump change in comparison to the damage that buying Devices & Services has caused. Deciding to make its own Windows smartphones looks to be a huge mistake for Microsoft. There is, however, some good news too.

Can new techniques in capturing and storing data help to ease the burden on IT teams and even help prevent breaches in the first place? We spoke to Perry Dickau, director of product management from data-aware storage provider DataGravity to find out.

Videos on Facebook are big business. As well as drugged up post-dentist footage, there is also huge advertising potential. Now Facebook has announced a new set of options for video publishers -- including the ability to limit who is able to see videos based on their age and gender.

A social network might not be the first place you would think of to try to keep something private, but a new 'secret video' option makes it possible to restrict access to those people who have a direct link. Other new options include the ability to prevent embedding on other sites, but it is the audience restriction settings that are particularly interesting.
