According to a recent blog post by LinkedIn, Twitter has decided to end a two and a half year partnership with the website. The partnership allowed users of the social networking site for business professionals to publish tweets directly to their LinkedIn profiles. Consumer Product Chief for Twitter Michael Sippey recently wrote a post on the site's developer blog that the changes were part of a move to "deliver a core Twitter consumption experience through a consistent set of products and tools."

This isn't too surprising as Twitter has been slowly trying to push out partners who show tweets on their websites. However, those efforts have also been primarily focused on mobile clients, the same place Twitter has been emphasizing its own offerings.

LinkedIn and Twitter users will still be able to post updates on LinkedIn and broadcast them to Twitter, though the content sharing will not go the other way. This actually goes along with what Twitter's overall strategy has been recently. The social network is welcoming of others sending content to Twitter but isn't so keen on having others use tweets as content on their sites.

The strange thing about all of this, however, is that Twitter just upgraded its own Facebook app, which crossposts tweets to users' Facebook profiles, which is the exact same thing that the partnership with LinkedIn allowed since the partnership between the two sites formed back in 2009.

Twitter has struggled with rule and practice consistency for some time now with its partners like LinkedIn. Developers who have created apps for viewing tweets have found themselves placed at a disadvantage by changes to Twitter's rules and the site's efforts to develop its own mobile clients.

ARM has just created a brand new, entry level version of its Mali graphics processor that, if incorporated, could expand the market of low cost Android tablets. Known as the Mali-450, this GPU is designed to help manufacturers build tablets that are less expensive than the ones currently leading the markets, like Apple's iPad which runs $399. However, these manufacturers still want good enough graphics performance to keep most users satisfied.

Touchscreens and HD video are pretty standard when it comes to tablets these days, with the GPUs in these devices accounting for a big share of the price you pay. In addition to that, more powerful GPUs take up more space on the CPU, which could also increase costs. A lot of manufacturers are looking for cheaper parts that offer decent graphics performance while also occupying less space. This is where the Mali-450 fits in.

The new GPU is offered with as many as eight cores and offers double the performance of its predecessor the Mali-400. The Mali-450 is also expected to appear in tablets in the first half of 2013 according to Director of Marketing for ARM's Media Processing Division Ian Smythe.

Tablet makers are showing an increased demand for a wide range of price and performance characteristics, which is where this new ARM GPU comes in . The company is planning on offering the Mali-T600 series for high-end devices and the Mali-400 series for low-end devices.

Both series will be able to do gaming and video playback but, according to Smythe, only the high-end parts will be able to handle "computational graphics". That includes things like matching points on two images to do facial recognition or stitching photographs together into a panorama. ARM is also developing a high-end part known as Skrymir (not to be confused with Skyrim, cheeky devils) which is due out sometime in 2014.
