Why a JavaScript hater thinks everyone needs to learn JavaScript in the next year - O'R... - 1 views

  • some extremely important game-changers: jQuery, JSON, Node.js, and HTML5.
  • .js has the potential to revolutionize web development. It is a framework for building high performance web applications: applications that can respond very quickly and efficiently to a high volume of incoming requests.
  • Google has started a revolution in JavaScript performance.
  • ...11 more annotations...
  • the number of JavaScript developers is huge.
  • HTML5 is about JavaScript
  • The power of HTML5 lies in what these tags allow you to create in JavaScript.
  • HTML5, then, isn't really a major advance in angle-bracket-based tagging; it's about enabling JavaScr
  • pt to do more powerful things
  • JavaScript has long been the workhorse for implementing dynamic features in HTML. But there have always been two problems: browser incompatibilities, and the awkwardness of working directly with the DOM. The JQuery library has elegantly solved both problems, and is the basis for modern client-side browser development.
  • The use of JavaScript has also exploded in databases.
  • document databases
  • for all three databases, a "document" means a JSON document, not a Word or Excel file.
  • JSON is really just a format for serializing JavaScript objects.
  • Web servers, rich web client libraries, HTML5, databases, even JavaScript-based languages: I see JavaScript everywhere.

    OK, this article gets my vote as the most important read of the year.  We all know that the the Web is the future of both computing and communications/connectivity.  But wha tis the future of the Web?  Uber coder Mike Loukides says it's JavaScript, and what a compelling case he builds.  This is a must read.  Key concepts are diigo highlighted :) excerpt: JavaScript has "grown up." I'm sure there are many JavaScript developers who would take issue with that judgement, and argue that JavaScript has been a capable, mature, and under-appreciated language all along. They may be right, though you can write any program in any complete programming language, including awful things like BASIC. What makes a language useful is some combination of the language's expressiveness and the libraries and tools available. JavaScript clearly passed the expressiveness barrier a long time ago, even if the ceremony required for creating objects is distasteful. But recently, we've seen some extremely important game-changers: jQuery, JSON, Node.js, and HTML5. JavaScript may have been a perfectly adequate language in the past, but these changes (and a few others that I'll point out) have made JavaScript a language that is essential for every developer to know. If there's one language you need to learn in the next year, it's JavaScript. Insightful comment: HTML5 is a JavaScript API, introducing new elements but significantly redefining ALL elements as objects or classes.  Elements can be expressed with tags.  Or, you can use DOM JavaScripting to create elements.

HTML5 Can Get the Job, But Can HTML5 Do the Job? - 2 views

    Great chart and HTM5 App development advice from pinch/zoom developer Brian Fling!   excerpt: In a post on pinch/zoom's blog Swipe, Fling discusses the "Anatomy of a HTML5 Mobile App" and what developers will need to get started, what the pitfalls are and why HTML5 is so difficult. HTML5 is a lot like HTML, just more advanced. Fling says that "if you know HTML, then chances are you'll understand what's new in HTML5 in under an hour." Yet, he also says that HTML5 is almost nothing without Javascript and CSS. Device detection, offline data, Javascript tools, testing, debugging and themes are issues that need to be resolved with the tools at hand. One of the big challenges that developers face is the need to fully comprehend Javascript. That starts from the most basic of codes on up. Fling says that many developers cannot write Javascript without the aid of frameworks like Prototype, MooTools, jQuery or Scriptaculous. That would not be so much of a problem if all an application consisted of was functionality and theme, but the data and multiple device requirements of apps and working with the HTML5 code means that troubleshooting a Web application can be extremely difficult if a developer does not know what to look for in Javascript. Fling breaks down the three parts of the Javascript stack that is required in building HTML5 apps - hybrid, core and device scripts. Then there is CSS. Fling likens CSS to the make, model, interior and attention to detail of a car. "Javascript definitely influences our experience as well, but they are the machinations out of view," Fling wrote. "We absolutely need it to be there, but as any Top Gear fan can tell you - power under the hood doesn't always equal a powerful experience." So, HTML5 can get the job. But can it do the job? Fling says yes, but with these caveats:

What ASP.NET Developers Should Know About jQuery - MIX Online - 0 views

  •  
    Recently the Rocketman and i have been arguing about webkit/Chromium DOM capabilities and limitations; like the failure to fully implement CSS3! Especially missing is support for CSS3 page layout / page break innovations. I realized that i didn't have a good understanding of browser DOM - client side issues, and came across this interesting post from Dave Ward concerning DOM and jQuery.
    The core issue behind my discussions with the Rocketman have to do with creating a DOM view from OpenXML and ODF documents, and then passing that view to the webkit/Chromium engine. So we weren't all that interested in cross browser support or in how IE8 handles DOM-JavaScript. Dave Ward however not only provides a good discussion about DOM-JavaScript and the importance of jQuery as a force of interoperability, he also points out that Microsoft supports jQuery - including direct support within Visual Studio!
    ".....Though JavaScript itself is a great programming language, the document object model (DOM) can be a web developer's worst nightmare.  The DOM is a method through which browsers expose an interface allowing JavaScript code to manipulate elements, handle events, and perform other tasks related to a document within the browser.  While almost every browser implements an ECMA standard version of JavaScript, their DOM implementations are inconsistent and quirky at best.  In fact, if you've had bad experiences with client-side programming in the past, it's likely that the DOM was the true source of your frustrations, not JavaScript itself.  This is exactly the pain point which jQuery addresses....
    ..... "Officially supported by Microsoft - For many Microsoft developers, this official blessing is the clincher. Not only will Microsoft begin including jQuery with Visual Studio, but it is part of the default ASP.NET MVC project template. What's more, Microsoft Product Support Services has already begun offering support for jQuery."....

Discoverer of JSON Recommends Suspension of HTML5 | Web Security Journal - 0 views

    Fascinating conversation between Douglas Crockford and Jeremy Geelan. The issue is that XSS - the Cross Site Scripting capabilities of HTML. and "the painful gap" in the HTML5 specification of the itnerface between JavaScript and the browser. I had to use the Evernote Clearly Chrome extension to read this page. Microsoft is running a huge JavaScript advertisement/pointer that totally blocks the page with no way of closing or escaping. Incredible. Clearly was able to knock it out though. Nicely done! The HTML5-XSS problem is very important, especially if your someone like me that sees the HTML+ format (HTML5-CSS3-JSON-JavaScript-SVG/Canvas) as the undisputed Cloud Productivity Platform "compound document" model. The XSS discussion goes right to the heart of matter of creating an HTML compound document in much the same way that a MSOffice Productivity Compound Document worked. The XSS mimics the functionality of of embedded compound document components such as OLE, DDE, ODBC and Scripting. Crack open any client/server business document and it will be found to be loaded with these embeded components. It seems to me that any one of the Cloud Productivity Platform contenders could solve the HTML-XSS problem. I'm thinking Google Apps, Zoho, SalesForce.com, RackSpace and Amazon - with gApps and Zoho clearly leading the charge. Also let me add that RSS and XMP (Jabber), while not normally mentioned with JSON, ought to be considered. Twitter uses RSS to transport and connect data. Jabber is of course a long time favorite of mine. excerpt: The fundamental mistake in HTML5 was one of prioritization. It should have tackled the browser's most important problem first. Once the platform was secured, then shiny new features could be carefully added. There is much that is attractive about HTML5. But ultimately the thing that made the browser into a credible application delivery system was JavaScript, the ultimate workaround tool. There is a painful gap

Google's Chrome Browser Sprouts Programming Kit of the Future "Node.js" | Wired Enterpr... - 1 views

    Good article describing Node.js.  The Node.js Summitt is taking place in San Francisco on Jan 24th - 25th.  http://goo.gl/AhZTD I'm wondering if anyone has used Node.js to create real time Cloud ready compound documents?  Replacing MSOffice OLE-ODBC-ActiveX heavy productivity documents, forms and reports with Node.js event widgets, messages and database connections?  I'm thinking along the lines of a Lotus Notes alternative with a Node.js enhanced version of EverNote on the front end, and Node.js-Hadoop productivity platform on the server side? Might have to contact Stephen O'Grady on this.  He is a featured speaker at the conference. excerpt: At first, Chito Manansala (Visa & Sabre) built his Internet transaction processing systems using the venerable Java programming language. But he has since dropped Java and switched to what is widely regarded as The Next Big Thing among Silicon Valley developers. He switched to Node. Node is short for Node.js, a new-age programming platform based on a software engine at the heart of Google's Chrome browser. But it's not a browser technology. It's meant to help build software that sits on a distant server somewhere, feeding an application to your PC or smartphone, and it's particularly suited to systems like the one Chito Manansala is building - systems that juggle scads of information streaming to and from other sources. In other words, it's suited to the modern internet. Two years ago, Node was just another open source project. But it has since grown into the development platform of the moment. At Yahoo!, Node underpins "Manhattan," a fledgling online service for building and hosting mobile applications. Microsoft is offering Node atop Windows Azure, its online service for building and hosting a much beefier breed of business application. And Sabre is just one of a host of big names using the open source platform to erect applications on their own servers. Node is based on the Javascript engine at th

Beyond jQuery: JavaScript tools for the HTML5 generation | HTML5 - InfoWorld - 0 views

  •  
    Good article covering lots of JavaScript Libraries and their specific uses. excerpt:  Over drinks, one person proclaimed, "No one programs in JavaScript, they just string together jQuery calls." This statement is certainly not true, but like a hand grenade, it gets close enough to make its point. jQuery sure seems to be everywhere, and with good reason: Its creators took all of the neat ideas from libraries like Prototype, Dojo, and Yahoo's YUI, then turned them into something that was just a tad easier to use. When jQuery nurtured fertile plug-in culture, the library became irreplaceable. One seemingly random estimate claimed that at least 70 percent of JavaScript is jQuery. While there is probably no scientific way to make such a blanket statement, the fact that someone would try is good enough.

Glassholes: A Mini NSA on Your Face, Recorded by the Spy Agency | Global Research - 0 views

  • eOnline reports: A new app will allow total strangers to ID you and pull up all your information, just by looking at you and scanning your face with their Google Glass. The app is called NameTag and it sounds CREEPY. The “real-time facial recognition” software “can detect a face using the Google Glass camera, send it wirelessly to a server, compare it to millions of records, and in seconds return a match complete with a name, additional photos and social media profiles.” The information listed could include your name, occupation, any social media profiles you have set up and whether or not you have a criminal record (“CRIMINAL HISTORY FOUND” pops up in bright red letters according to the demo).
  • Since the NSA is tapping into all of our digital communications, it is not unreasonable to assume that all of the info from your digital glasses – yup, everything – may be recorded by the spy agency. Are we going to have millions of mini NSAs walking around recording everything … glassholes? It doesn’t help inspire confidence that America’s largest police force and Taser are beta-testing Google Glasses. Postscript: I love gadgets and tech, and previously discussed the exciting possibilities of Google Glasses. But the NSA is ruining the fun, just like it’s harming U.S. Internet business.

ODF Plugfest: Making office tools interoperable [LWN.net] - 0 views

  • ODF on the web An especially interesting project that was presented is WebODF, which wants to bring ODF to the web. Jos van den Oever started from the observation that a lot of office suites are moving into the "cloud". Examples are Microsoft Live Office, Google Docs, and Zoho. But where are the free software alternatives for the cloud? For OpenOffice.org, KOffice, AbiWord, and Gnumeric, there are none that have a cloud version with ODF support. That was the motivation for Jos to start a project to fill in this gap and let users view and edit ODF documents on the web without losing control of the document into some company's servers. The strategy Jos followed was to use just HTML and JavaScript for the web application. The application then loads the XML stream of the ODF document as is into the HTML document and puts it into the DOM tree. Styling is done by applying CSS rules that are directly derived from the <office:styles> and <office:automatic-styles> elements in the ODF document. That is how WebODF was born; it is a project with the initial goal of creating a simple ODF viewer and editor for offline and online use, implemented in HTML5. The small code base consists of one HTML5 file and eight JavaScript files, each of which is a few hundred lines of code. The most interesting part is that it doesn't need server-side code execution: the JavaScript code is executed in the user's browser and saving the document to the web server is done using WebDAV. It supports both the Gecko and WebKit HTML engines. There is also an implementation on top of QtWebKit, which is for better desktop integration, and an ODFKit implementation. This means that WebODF is an easy way to add ODF support to almost any application, be it in HTML, Gtk, or QML. KO GmbH has received funding from NLnet to improve the current WebODF prototype and see how far the idea goes. Interested readers can try the online demo.

    Google releases JavaScript alternative Web application programming language.  Release includes Cloud SQL, a cloud computing database to write Web apps against - using either JavaScript or DART. excerpt: Google on Monday introduced a preview version of Dart, its new programming language for Web applications. The introduction was widely expected, not only because the announcement was listed on the GOTO developer conference schedule, but because a Google engineer described the language and its reason for being in a message sent to a developer mailing list late last year. "The goal of the Dash [Dart's former name] effort is ultimately to replace JavaScript as the lingua franca of Web development on the open Web platform," said Google engineer Mark S. Miller in his post last year.

    White paper from Intel discusses HTML5 and the future of computing. Intro: Computer programmers have been grappling with cross-platform issues since there was a second platform. Since then, the number of issues has rapidly increased. Today's developers can target at least four operating systems (plus their fragments), running on devices with all shapes, sizes, resolutions, persistence levels, input methods, carrier networks, connection speeds and states, UI conventions, app stores, deployment and update mechanisms, and on and on. Many of the world's developers once looked to Java* as the shining knight of cross-platform development. Indeed, the structured language of Sun* (and now Oracle) continues to solve many cross-platform issues. But it also introduces obstacles, not the least of which is a class structure that heavily burdens even the tiniest of program functions. Java's heft grew still more burdensome as developers turned to the browser for app delivery; Java applets are black boxes that are as opaque to the browser as the language is closed to the developer (with all due deference to the JCP). Around the same time Java was fuelling the browser wars, a like-named interpreted language was beginning to emerge. First called Mocha, later LiveScript, and finally JavaScript*, the language proved more useful than Java in some ways because it could interact with the browser and control content display using HTML's cascading style sheets (CSS). JavaScript support soon became standard in every browser. It is now the programming language of HTML5, which is currently being considered by the World Wide Web Consortium as the next markup-language standard. To better understand HTML5-why it is where it is and where it's going- Intel® Software Adrenaline turned to Moh Haghighat, a senior principal engineer in the Developer Products Division of Intel's Software and Services Group. Moh was the technical lead from Intel's side on the first JavaScript

GMailr: An Unofficial Javascript API for GMail - ReadWriteCloud - 1 views

  •  
    Google has pretty much given up on developing a JavaScript API for GMail. There was once a Greasemonkey script Google developed for GMail but that broke and Google shows no sign of fixing it. James Yu is now trying to fix that scenario with GMailr, a JavaScript API for GMail. It is made from the code he wrote for 0Boxer, an extension for GMail that turns organizing your inbox into a game. Yu is also a lead developer at Scribd. Yu said developing the API took him on a path fraught with frustrations and dead ends. He writes there is supported official JavaScript API for Gmail. The Greasemonkey script is broken and no one has yet released a frontend API for Gmail. He said he needed access to the various user actions in the UI as the backend APIs were not going to work as he wished. He decided to write his own library from scratch.

Apple, Microsoft Challenged By Streaming Software Plan - Cloud - 0 views

  •  
    Very interesting the way JavaScript Libraries are continuing to challenge Native Code for Web Application dominance.    excerpt: "The code library, ORBX.js, can be thought of as a cloud-based alternative to Google's Native Client technology. It permits Linux, OS X and Windows applications to run on remote servers and to be presented in a Web browser." "With ORBX.js, native code and legacy applications can be hosted in the cloud (e.g. Amazon EC2), and stream interactive graphics, 3D rendering or low latency video to a standard HTML5 page without using plugins or native code, or even the video tag (which, like Google NaCL,is vendor specific - ORBX.js works on all five major browsers)," explained Otoy founder and CEO Jules Urbach in an email. "The video codec created for ORBX.js can decode 1080p60 at a quality on par with H.264, using only JavaScript." "With ORBX.js and a cloud service provider, you could conceivably run Value's PC Steam client on an Apple iMac or Google Chromebook. You could run Autodesk 3DS Max 2014 on an Android Nexus 7 tablet. You could run a big budget, graphically demanding game title like Left 4 Dead 2 in a Web browser, without any plugins, Flash, Java, NaCL or other supporting technology."

10 most useful Google Chrome experiments | ITworld - 1 views

    When it comes to presenting graphically oriented programs through a browser, the usual go-to development platforms have been Adobe Flash and -- to a lesser extent -- Microsoft Silverlight. But other, more open technologies are starting to show promise. The 10 best Chrome extensions for work and play |Watch a slideshow of this review. That's what Google aims to highlight on Chrome Experiments, a Web site that showcases JavaScript programs that deliver a rich user-graphics experience. Of the nearly 80 projects featured on Chrome Experiments, the majority are graphic demos. As impressive as such eye candy is, they're not good examples of how capable JavaScript can be for running graphically-oriented applications that are actually useful. But there are a few notable ones, which we present here. (Despite the site's name, these programs should run on any browser that supports JavaScript.)

Modernizr: A JavaScript Library for Open Web HTML5-CSS3 technologies - 1 views

  •  
    Modernizr is a small and simple JavaScript library that helps you take advantage of emerging web technologies (CSS3, HTML 5) while still maintaining a fine level of control over older browsers that may not yet support these new technologies. Modernizr uses feature detection to test the current browser against upcoming features like rgba(), border-radius, CSS Transitions and many more. These are currently being implemented across browsers and with Modernizr you can start using them right now, with an easy way to control the fallbacks for browsers that don't yet support them. Additionally, Modernizr creates a self-titled global JavaScript object which contains properties for each feature; if a browser supports it, the property will evaluate true and if not, it will be false. Lastly, Modernizr also adds support for styling and printing HTML5 elements. This allows you to use more semantic, forward-looking elements such as , and without having to worry about them not working in Internet Explorer. Another great catch by Marbux!  He's on fire today.

    [Blush.] Should be mentioned that Modernizr comes with an MIT-BSD dual license. So compatible with both GPL and proprietary apps.

Strobe Launches Game-Changing HTML5 App Platform | TechCrunch - 1 views

  •  
    Today, Strobe Inc. is launching a new platform that helps developers build HTML5-based Web applications for desktops, smartphones and tablets, and centrally manage them from a single interface. The launch is a major leap forward in HTML5 app development. From one interface, teams can manage code (both test code and production code), configure the app's deployment across platforms (Web, Android, iOS, etc.), add additional services (social, push notifications, authentication, etc.), and even track analytics within an easy-to-use dashboard. In short, it's a comprehensive platform that makes building apps with Web technologies, like HTML5 and JavaScript, not just possible, but easy, straightforward and fast. The company was co-founded by Ruby on Rails Core Team member Carl Lerche, Ruby on Rails, jQuery and SproutCore Core team member Yehuda Katz, and Charles Jolley, formerly the JavaScript Frameworks Manager for Apple. At Apple, Jolley worked on Apple's Web products like MobileMe and iCloud. He's also the creator of the open source JavaScript framework, SproutCore, which powered Apple's Web services and is now a key part of the Strobe platform. In addition to SproutCore, Strobe also uses PhoneGap, the popular HTML5 app platform. PhoneGap lets developers author apps using Web technologies then deliver them in a native wrapper to the iTunes App Store, Android Marketplace and other app stores. It also happens to integrate nicely with SproutCore.

In Cryptography, Advances in Program Obfuscation | Simons Foundation - 0 views

  • “A program obfuscator would be a powerful tool for finding plausible constructions for just about any cryptographic task you could conceive of,” said Yuval Ishai, of the Technion in Haifa, Israel. Precisely because of obfuscation’s power, many computer scientists, including Sahai and his colleagues, thought it was impossible. “We were convinced it was too powerful to exist,” he said. Their earliest research findings seemed to confirm this, showing that the most natural form of obfuscation is indeed impossible to achieve for all programs. Then, on July 20, 2013, Sahai and five co-authors posted a paper on the Cryptology ePrint Archive demonstrating a candidate protocol for a kind of obfuscation known as “indistinguishability obfuscation.” Two days later, Sahai and one of his co-authors, Brent Waters, of the University of Texas, Austin, posted a second paper that suggested, together with the first paper, that this somewhat arcane form of obfuscation may possess much of the power cryptographers have dreamed of. “This is the first serious positive result” when it comes to trying to find a universal obfuscator, said Boaz Barak, of Microsoft Research in Cambridge, Mass. “The cryptography community is very excited.” In the six months since the original paper was posted, more papers have appeared on the ePrint archive with “obfuscation” in the title than in the previous 17 years.

Google Chrome 5 WebKit - Firefox - Opera Comparisons - BusinessWeek - 0 views

  •  
    Chrome runs as close as any browser can to the bleeding edge of Web standards. Though it uses the same open source WebKit rendering engine as Safari, it doesn't reliably support the controversial, proprietary CSS3 transformation and animation tricks that Apple's built into Safari. However, like every browser I tested, it earned a perfect score in a compatibility test for CSS3 selectors, and it joined Safari and Opera with a flawless score of 100 in the Acid3 web standards benchmark. Chrome 5 also supports both Apple's H.264 codec and Mozilla's preferred open source Ogg Theora technology for plugin-free HTML5 video, and it beautifully played back HTML5 demo videos from YouTube and Brightcove. In XHTML and CSS tests, Chrome was surprisingly slower than Safari, despite their shared rendering engine -- but the race was close. Safari rendered a local XHTML test page in 0.58 seconds to Chrome's 0.78 seconds, and a local CSS test page in 33 milliseconds to Chrome's 51 milliseconds. Note that Chrome still rendered XHTML more than twice as fast as Opera (1.67 seconds) and left Firefox (12.42 seconds--no, that's not a typo) eating its dust. In CSS, it also beat the pants off Opera (193 milliseconds) and Firefox (342 milliseconds). But Chrome shines brightest when handling JavaScript. Its V8 engine zipped through the SunSpider Javascript benchmark in 448.6 milliseconds, narrowly beating Opera's 485.8 milliseconds, and absolutely plastering Firefox's 1,161.4 milliseconds. However, Safari 5's time of 376.3 miliseconds in the SunSpider test beat Chrome 5 handily.

WhatsApp Encryption Said to Stymie Wiretap Order - The New York Times - 0 views

  • While the Justice Department wages a public fight with Apple over access to a locked iPhone, government officials are privately debating how to resolve a prolonged standoff with another technology company, WhatsApp, over access to its popular instant messaging application, officials and others involved in the case said. No decision has been made, but a court fight with WhatsApp, the world’s largest mobile messaging service, would open a new front in the Obama administration’s dispute with Silicon Valley over encryption, security and privacy.WhatsApp, which is owned by Facebook, allows customers to send messages and make phone calls over the Internet. In the last year, the company has been adding encryption to those conversations, making it impossible for the Justice Department to read or eavesdrop, even with a judge’s wiretap order.
  • As recently as this past week, officials said, the Justice Department was discussing how to proceed in a continuing criminal investigation in which a federal judge had approved a wiretap, but investigators were stymied by WhatsApp’s encryption.The Justice Department and WhatsApp declined to comment. The government officials and others who discussed the dispute did so on condition of anonymity because the wiretap order and all the information associated with it were under seal. The nature of the case was not clear, except that officials said it was not a terrorism investigation. The location of the investigation was also unclear.
  • To understand the battle lines, consider this imperfect analogy from the predigital world: If the Apple dispute is akin to whether the F.B.I. can unlock your front door and search your house, the issue with WhatsApp is whether it can listen to your phone calls. In the era of encryption, neither question has a clear answer.Some investigators view the WhatsApp issue as even more significant than the one over locked phones because it goes to the heart of the future of wiretapping. They say the Justice Department should ask a judge to force WhatsApp to help the government get information that has been encrypted. Others are reluctant to escalate the dispute, particularly with senators saying they will soon introduce legislation to help the government get data in a format it can read.
