Facebook Testing New Navigation Menu

California – Facebook amid redesign navigation bar for iOS and Android app for easy use. Some Facebook users reported that the new navigation bar has appeared at the bottom of the screen.

But, it was not all users can get the new navigation bar that is still a beta version of it. With the addition of the menu at the bottom, the side navigation bar is now no longer in the beta version of the Facebook application.

Android users who already have a new navigation bar using Facebook beta version of Google Play Store. While the Apple iPhone users who see the new navigation bar that has installed the regular version of Facebook.

Android users who have installed the Facebook application is given a link to download the beta version of Facebook when they install updates. This all shows the changes coming from the server.

There is no warranty on the features of the new navigation bar. Current navigation bar is still considered to iOS or Android app.

Parallel and Concurrent Programming in Haskell

As one of the developers of the Glasgow Haskell Compiler (GHC) for almost 15 years, I have seen Haskell grow from a niche research language into a rich and thriving ecosystem. I spent a lot of that time working on GHC’s support for parallelism and concurrency. One of the first things I did to GHC in 1997 was to rewrite its runtime system, and a key decision we made at that time was to build concurrency right into the core of the system rather than making it an optional extra or an add-on library. I like to think this decision was founded upon shrewd foresight, but in reality it had as much to do with the fact that we found a way to reduce the overhead of concurrency to near zero (previously it had been on the order of 2%; we’ve always been performance-obsessed). Nevertheless, having concurrency be non-optional meant that it was always a first-class part of the implementation, and I’m sure that this decision was instrumental in bringing about GHC’s solid and lightning-fast concurrency support.

Haskell has a long tradition of being associated with parallelism. To name just a few of the projects, there was the pH variant of Haskell derived from the Id language, which was designed for parallelism, the GUM system for running parallel Haskell programs on multiple machines in a cluster, and the GRiP system: a complete computer architecture designed for running parallel functional programs. All of these happened well before the current multicore revolution, and the problem was that this was the time when Moore’s law was still giving us ever-faster computers. Parallelism was difficult to achieve, and didn’t seem worth the effort when ordinary computers were getting exponentially faster.

Around 2004, we decided to build a parallel implementation of the GHC runtime system for running on shared memory multiprocessors, something that had not been done before. This was just before the multicore revolution. Multiprocessor machines were fairly common, but multicores were still around the corner. Again, I’d like to think the decision to tackle parallelism at this point was enlightened foresight, but it had more to do with the fact that building a shared-memory parallel implementation was an interesting research problem and sounded like fun. Haskell’s purity was essential—it meant that we could avoid some of the overheads of locking in the runtime system and garbage collector, which in turn meant that we could reduce the overhead of using parallelism to a low-single-digit percentage. Nevertheless, it took more research, a rewrite of the scheduler, and a new parallel garbage collector before the implementation was really usable and able to speed up a wide range of programs. The paper I presented at the International Conference on Functional Programming (ICFP) in 2009 marked the turning point from an interesting prototype into a usable tool.

All of this research and implementation was great fun, but good-quality resources for teaching programmers how to use parallelism and concurrency in Haskell were conspicuously absent. Over the last couple of years, I was fortunate to have had the opportunity to teach two summer school courses on parallel and concurrent programming in Haskell: one at the Central European Functional Programming (CEFP) 2011 summer school in Budapest, and the other the CEA/EDF/INRIA 2012 Summer School at Cadarache in the south of

Sony Xperia Sailing Release 6.4 Inches in Indonesia

Located in Jakarta, Wednesday (24/7), Sony introduced the Xperia Z Ultra which has a 6.4-inch screen with Full HD TRILUMINOS X-Reality Engine.

This display capability is claimed to provide a better experience, especially with the screen size is much larger than the original version of the Xperia Z.

Very powerful embedded processors, the Qualcomm Snapdragon 2.2GHz quad-core 800. Xperia Z Ultra is also supported by 2GB of RAM and 16GB of internal memory plus a microSD slot.

Interestingly, despite carrying a variety of hardware on board, it is able to present the Sony Xperia Z Ultra designs become thinner. In fact, the thickness is only 6.5 mm into the MURI.

As in the previous Z series Xperia, Xperia Z Ultra smartphone is also quite tough waterproof and dust to IP55 and IP58 certification.

Unfortunately, some of the above advantages make Sony should cut the camera was 13 megapixels to 8 megapixels alone. However, Sony claims the camera is equipped with Exmor RS Mobileserta HDR is able to produce extremely sharp images.

Sony did not forget to announce the presence of Sony Music JIVE application in Xperia Z Ultra. Through these apps, users can download and streaming his favorite songs for free for 6 months. Not only that, there are also apps Path and e-reader Wayang Force which has been available since the beginning of the purchase Xperia Z Ultra.

“Xperia Z Ultra available in early August with two colors, namely Black and White,” said Ika Paramita, Marketing Manager of Sony Mobile Communications Indonesia. About the price, that puts smartphones via NFC Connectivity One Touch is priced at 7.5 million dollars worth.

Getting to know Jack Dorsey, the Twitter Author

Is one of the requirements to be successful is a must have dropped out of college? For those who do not agree with that statement, Bill Gates, Steve Jobs, Mark Zuckerberg has proved the above statement is true.

Now, a New York University student born 19 November 1976, Jack Dorsey, co-joined to the above statement agrees with being one of the success with the brilliant work; Twitter.

Perhaps the name of the new Jack Dorsey first heard in your ears, or just this once you read it. In fact he was the one creating ‘toy’ in today’s internet era that could be very, very you gandrungi.

He is the creator of a social network with the concept of micro-blogging, Twitter. That the college years never removed from the campus where he learned about the computer.

Dorsey was born in St. Louis, Missouri, 37 years ago. And there precisely he grew up with curiosity about computers and communications were also great. Dorsey teen has started his desire to dive into programming since he was 15 years old.

And continued when he was in high school, Bishop DuBourg High School name. Where he pursue any science, and especially, computers and programming.

Dorsey teens start to find out and follow your passion when he was struck with a computer program that manages and coordinates a taxi passing by the system very well organized and quick.

How cars taxi, or car delivery can regularly meet and work quickly calls. Of interest arises where a similar program to create a more sophisticated, when he was only 15 years old.

Dorsey adults continue his studies at the Missouri University of Science and Technology. The study period was completed and continued to move to New York University who also never finish it. Or in another sense, Dorsey dropped out of university.

Because it takes time and concentration to build his company. Dorsey moved to Oakland, California, in 2000 and built a company engaged in the field of programming.

He sold the software on line pengkoordinir taxi he had ever made as a teenager in the web that he made himself. And the company continues to grow by selling software creation via the Internet.

Through his company is the way Dorsey met with people like Biz Stone and Evan Williams who later would become his partner in founding Twitter.

What’s in your mind when you want to create a Twitter Dorsey? Narrated by Biz Stone, Dorsey has wild ideas in his head. “Just imagine if we could share with our friends about what we are doing and what we feel now, imagine. Is not it great? “Said Dorsey.

Biz Stone, a former CEO of Odeo, and Evan Williams-one of the founders blogger, agrees that desire and build company called Obvious, who would soon be renamed Twitter.

Social networking on the initial launch is not so attractive to everyone, but it has now become one of the most social media enjoyed by most citizens of the world. Which may also be one of the ‘toy’ bored repellent for you.
