app developers help, HTML5 and Social Protection
In her keynote address on the second day of the IDF was Intel's software chief Renée James one with the theme "The era of transparent program" focused primarily on the app development and app developers. Few could yet live on the income from the various stores. A third of all apps bring, according to James at most $ 500 a month, on average, the income is from 1200 to 3900 U.S. dollars.
Since one must make it easier for programmers to develop for multiple platforms. The key here are browser apps with HTML5 and JavaScript. 40 percent of developers were already working with HTML5, while 40 percent plan to soon. Intel will support the diverse, should be about the developed together with Mozilla plugin River Trail, which teaches the JavaScript Multi-threading and SSE and AVX use. 2013 River Trail will be included by default in Firefox.
James presented the company with a kit MobBase MixMatchMusic.com, with which one can simply click together an HTML5 app that will appear in various app stores. And finally gave James announced the formation of the Intel Developer Zone, which provides developers with software, documentation, forums and above all with the same distribution channels, to the App Store.
In addition, James teamed up with McAfee co-president Mike DeCesare one to work with the 2011 purchased security software company. Besides developments for secure PC, McAfee now also takes care of the social networks and social protection. Thus, a selected circle of friends but look at Facebook pictures, but can not copy. A beta version of McAfee Social Protection can be downloaded from Facebook. However, has been questioned in the subsequent question and answer session, so if you really can copy protect an image shown on the screen - ultimately you can do that also photograph the simple.
Mark Zuckerberg says Facebook focuses on its mobile business
Facebook founder Mark Zuckerberg has reconciled with his first interview after the botched IPO investors a bit. On the U.S. technology blog TechCrunch Disrupt conference organized, he explained that the focus of the social network lies in the mobile business. So far, here's advertising revenues are disappointing, what is considered the main reason for the collapse of the stock.
"Over the next three to five years, the central question will be how well we hit the mobile space," said Zuckerberg. "Depends on all the company's development." Facebook had been renewed until August his much criticized iPhone app and is working on a new Android app. An exact date of when it is ready, not named Zuckerberg.
According to the submissions of the Facebook-chief and founder of the price of Facebook shares rose more than 3 percent after trading at 20.09 U.S. dollars. But that is still far short of the $ 38 that the paper cost the IPO in May. "The development of the stock is obviously disappointing," said Zuckerberg. However, it was not the first and downs in the history of the company.
Building its own smartphone Zuckerberg issued again clearly rejected. "It would be totally the wrong strategy for us," he said. "Let us assume again, we would build a phone, purely hypothetical. We would reach perhaps 10 million or 20 million people." Facebook would however be represented on any smartphone.
Apps for Google with new functions
In addition, presentations can also be viewed on iPhone or iPad. It should also be the speaker notes area, also can be found in the full screen mode and with wiping gestures between films and back again. In addition, new folder is created, files are stored in folders, and content can be uploaded directly from the device in the Google cloud.
The enhancements to the Android app version 1.1.4.12 include according to Google along with the new capabilities of the iOS version, the ability to add comments, reply to existing comments and view spreadsheets in Google documents.
In the future, Google still further features in view, among other native editing and real-time collaboration for Google Spreadsheets spreadsheet. The apps are available via the Play-Store or on iTunes for download. Be provided at least Android 2.1 or iOS 5.0.
WhatsApp makes slightly authentication
The popular SMS WhatsApp competitor has introduced an encryption. Now reported, the British web developer Sam Granger, as the authentication for the web interface of the service takes place on Android: The program uses the unique device identifier (IMEI) to it to create a simple regenerative key.
According to Granger WhatsApp use simply the inverted IMEI and create it without further "Salt" an MD5 hash. Since acting as the user's phone number, could allow the attacker to find the necessary data easily with standard Android interface. A program to determine the IMEI and the phone number was written quickly and set under a false pretext to Google Play.
Then it would be possible to use the WhatsApp service with these credentials, Granger writes. Although there is no official API for it, but on the net there is software that promises access to WhatsApp web services. Thus, it may be possible to send messages that appear to come from the users of the hacked accounts.
So far there is no information on how WhatsApp handles the authentication on other platforms. Apple's iOS has approximately unlike Android no official interface with which we can calculate the IMEI. The phone number, so the user name sent, the program the way despite the recent introduction of encryption remains in plain text.
WhatsApp uses a version of the XMP protocol for exchanging messages, the number of Instant Messenger. The app runs on all relevant mobile platforms.
Halide - new programming language for applications for image processing
Researchers from the "Computer Science and Artificial Intelligence Laboratory" (CSAIL) at MIT (Massachusetts Institute of Technology) have introduced a new programming language halides. It will facilitate the development of applications for image processing on modern computer systems. With this embedded DSL (Domain Specific Language) is the efficient use of algorithms, for example, Camera Raw pipelines, bilateral grid, Laplace filtering or image sharing possible.
Halide-programs should be not only easier to write and to read as image processing code in other conventional programming languages. Rather, the promises automated code optimization in a significantly faster execution Halide (PDF), even compared to more complex optimization händischer - the researchers say up to one-third shorter code for up to six times higher processing speed. One of the major factors is a high degree of parallelization Maximization of individual processes.
When embedded in C + + runs on platforms such as halides x86-64/SSE, ARM v7/NEON and CUDA. It supports SIMD units, multiple cores, and complex memory hierarchies. The compiler can be applied to Mac OS X systems (6.10 to 8.10, the team sets itself a) install and mainstream Linux distributions like Ubuntu (12.04). Builds for Windows should be technically possible, but the researchers tried or tested was. Halide is open source and licensed under the MIT license. The source code for the compiler and for halide itself can be downloaded from GitHub.
