Asm.js Gets Faster 289

Posted by timothy from the getting-better-all-the-time dept.
mikejuk writes "Asm.js is a subset of standard JavaScript that is simple enough for JavaScript engines to optimize. Now Mozilla claims that with some new improvements it is at worst only 1.5 times slower than native code. How and why? The problem with JavaScript as an assembly language is that it doesn't support the range of datatypes that are needed for optimization. This is good for human programmers because they can simply use a numeric variable and not worry about the difference between int, int32, float, float32 or float64. JavaScript always uses float64 and this provides maximum precision, but not always maximum efficiency. The big single improvement that Mozilla has made to its SpiderMonkey engine is to add a float32 numeric type to asm.js. This allows the translation of float32 arithmetic in a C/C++ program directly into float32 arithmetic in asm.js. This is also backed up by an earlier float32 optimization introduced into Firefox that benefits JavaScript more generally. Benchmarks show that firefox f32 i.e. with the float32 type is still nearly always slower than native code, it is now approaching the typical speed range of native code. Mozilla thinks this isn't the last speed improvement they can squeeze from JavaScript. So who needs native code now?"

Google's Dart Becomes ECMA's Dart 190

Posted by timothy from the trying-for-traction dept.
mikejuk writes "Google's Dart just reached version 1.0, but now it seems that it has aspirations to being an international standard. The question is will this make any difference to the language's future? Given that Google effectively owns Dart, what advantage does standardization bring? The answer to what Google thinks it brings is indicated in the Chromium blog: 'The new standardization process is an important step towards a future where Dart runs natively in web browsers.' and this seems reasonable. A standard is something that would be required before other browser makers decided to fall in line and support native Dart. It is probably a necessary but far from sufficient condition, however, with Microsoft, Apple and Mozilla having other interests to further. Last but not least, having the backing of a standard might just encourage possible users to believe that the language won't sink if Google gets distracted with other projects and decides that Dart is dispensable. However, a strong open source development community capable of supporting Dart without Google's input would be a better reassurance. If you want to help, Google would like you to join the committee. After all, it still doesn't have a Vice Chair. So can we expect to see ECMA CoffeeScript or TypeScript in the near future? Probably not."

Famo.us To Open Source Rendering Engine Replacement JavaScript Framework 48

Posted by Soulskill from the layers-of-complexity dept.
snydeq writes "Famo.us has announced it will be open sourcing its framework for achieving native app performance within the browser, InfoWorld reports. 'Why so much fuss over another JavaScript framework? Mainly because it is unlike any other framework out there: Famo.us replaces the browser's rendering engine with its own, which is written entirely in JavaScript, and fuels it with the GPU acceleration provided by CSS's 3D transformation functions. Most any device these days that can run a modern browser — even a modest smartphone — has some kind of GPU supporting it, so why not leverage that? Armed with Famo.us, developers can maintain a single code base that performs well across many platforms.' Demo code is available on Codepen. Famo.us is also partnering with Firebase, a database as a service for mobile and Web apps."

Ninth Anniversary of Firefox 1.0 Release 153

Posted by Unknown Lamer from the time-flies dept.
Nine years ago today, Firefox 1.0 was released. Mozilla writes "Mozilla created Firefox to be an amazingly fun, safe, and fast Web browser that embodies the values of our mission to promote openness, innovation and opportunity online. In the nine years since we first launched Firefox, we have moved and shaped the Web into the most valuable public resource of our time." The first release of the little project to write a lighter alternative to Seamonkey is a bit over a year older.

Mozilla Backtracks On Third-Party Cookie Blocking 173

Posted by Unknown Lamer from the w3c-google-mozilla-sell-out-together dept.
An anonymous reader writes "Remember when Mozilla announced that it would soon block third-party cookies by default? Not so fast. According to a new behind-the-scenes report in the San Francisco Chronicle, 'it's not clear when it will happen — or if it will at all.' Mozilla's leadership is apparently no longer committed to the feature, and the related Cookie Clearinghouse collaboration is delayed well into 2014. Who's to blame? According to Dan Auerbach, Staff Technologist at the Electronic Frontier Foundation, 'The ad industry has a ton of people, basically lobbyists, who spent a lot of time trying to convince Mozilla this was bad for the economy... I think they were somewhat successful.' Not a good showing for the purportedly pro-user organization."

Cisco Releases Open Source "Binary Module" For H.264 In WebRTC 95

Posted by Unknown Lamer from the bait-and-switch dept.
SD-Arcadia writes "Mozilla Blog: 'Cisco has announced today that they are going to release a gratis, high quality, open source H.264 implementation — along with gratis binary modules compiled from that source and hosted by Cisco for download. This move enables any open source project to incorporate Cisco's H.264 module without paying MEPG LA license fees. Of course, this is not a not a complete solution. In a perfect world, codecs, like other basic Internet technologies such as TCP/IP, HTTP, and HTML, would be fully open and free for anyone to modify, recompile, and redistribute without license agreements or fees. Mozilla is fully committed to working towards that better future. To that end, we are developing Daala, a fully open next generation codec. Daala is still under development, but our goal is to leapfrog H.265 and VP9, building a codec that will be both higher-quality and free of encumbrances.'"

How Your Compiler Can Compromise Application Security 470

Posted by Soulskill from the my-compiler-levels-me-out dept.
jfruh writes "Most day-to-day programmers have only a general idea of how compilers transform human-readable code into the machine language that actually powers computers. In an attempt to streamline applications, many compilers actually remove code that it perceives to be undefined or unstable — and, as a research group at MIT has found, in doing so can make applications less secure. The good news is the researchers have developed a model and a static checker for identifying unstable code. Their checker is called STACK, and it currently works for checking C/C++ code. The idea is that it will warn programmers about unstable code in their applications, so they can fix it, rather than have the compiler simply leave it out. They also hope it will encourage compiler writers to rethink how they can optimize code in more secure ways. STACK was run against a number of systems written in C/C++ and it found 160 new bugs in the systems tested, including the Linux kernel (32 bugs found), Mozilla (3), Postgres (9) and Python (5). They also found that, of the 8,575 packages in the Debian Wheezy archive that contained C/C++ code, STACK detected at least one instance of unstable code in 3,471 of them, which, as the researchers write (PDF), 'suggests that unstable code is a widespread problem.'"

Chrome Will End XP Support in 2015; Firefox Has No Plans To Stop 257

Posted by timothy from the dragged-into-the-same-grave dept.
Billly Gates writes "Microsoft is ending support for Windows XP in 2014. Fortunately for its users who want to keep browsing the web, Google is continuing to support Chrome until at least 2015. Firefox has no current plans to end support for XP. Hopefully this will delay the dreaded XPopacalypse — the idea that a major virus/worm/trojan will take down millions of systems that haven't been issued security patches. When these browsers finally do end XP support, does it mean webmasters will need to write seperate versions of CSS and JavaScript for older versions if the user base refuses to leave Windows XP (as happened with IE6)?" Update: 10/29 17:31 GMT by S : Changed headline and summary to reflect that Mozilla doesn't have plans to drop XP support any time soon.

Mozilla Location Service: Geolocation Lookups From Cell Towers and WiFi Data 46

Posted by samzenpus from the where-in-the-world dept.
An anonymous reader writes "Mozilla today launched an experimental pilot project called Mozilla Location Service. The organization explains its goal is to provide geolocation lookups based on publicly observable cell tower and WiFi access point information. Mozilla admits that many commercial services already exist in this space, but it wants to provide a public one. The company points out there isn't a single 'large' public service that provides this data, which is becoming increasingly important when building various parts of the mobile ecosystem."

LG Launches Its Firefox OS Phone Fireweb for $200 91

Posted by Unknown Lamer from the mozilla-prepares-to-eat-google dept.
SmartAboutThings writes "LG has launched the Fireweb Firefox OS smartphone in a joint event with the Telefonica Vivo carrier. The Fireweb Firefox OS smartphone will be available for around $200 and will join the Alcatel One Touch Fire which Telfonia is launching in Brazil, starting today. Mexico, Peru, and Uruguay are the next countries to get it. The Fireweb smartphone is LG's very first Firefox OS device and it increases the small number of OEMs that have released Firefox OS devices on the market. The smartphone has a 4-inch screen with a 480 x 320 display, a 1GHz Qualcomm processor and 4GB internal storage that can be expanded with the microSD card slot by up to 32GB. It has a 5-megapixel cameras that comes with both autofocusing and an LED flash, which is a first for Firefox OS phones." Hopefully an OEM releases a Firefox OS phone with beefier hardware, but you can't argue with the price.

Firefox's Blocked-By-Default Java Isn't Going Down Well 362

Posted by Soulskill from the teaching-grandma-to-click-through-dialog-boxes dept.
JG0LD writes "The Firefox web browser will, henceforth, require users to manually activate Java objects on sites that they visit, Mozilla has confirmed. This even affects up-to-date versions of Java, which you can see on the block list. The change is aimed at improving security and moving away from a dependence on proprietary plug-ins, but critics say it will cause untold headaches for developers, admins and less-technical end-users.

Tim Berners-Lee, W3C Approve Work On DRM For HTML 5.1 307

Posted by timothy from the concentrated-benefit-diffuse-harm dept.
An anonymous reader writes "Danny O'Brien from the EFF has a weblog post about how the Encrypted Media Extension (EME) proposal will continue to be part of HTML Work Group's bailiwick and may make it into a future HTML revision." From O'Brien's post: "A Web where you cannot cut and paste text; where your browser can't 'Save As...' an image; where the 'allowed' uses of saved files are monitored beyond the browser; where JavaScript is sealed away in opaque tombs; and maybe even where we can no longer effectively 'View Source' on some sites, is a very different Web from the one we have today. It's a Web where user agents—browsers—must navigate a nest of enforced duties every time they visit a page. It's a place where the next Tim Berners-Lee or Mozilla, if they were building a new browser from scratch, couldn't just look up the details of all the 'Web' technologies. They'd have to negotiate and sign compliance agreements with a raft of DRM providers just to be fully standards-compliant and interoperable."
