Siding with HTML over XHTML, My Decision to Switch - Monday By Noon - 0 views

  • Publishing content on the Web is in no way limited to professional developers or designers, much of the reason the net is so active is because anyone can make a website. Sure, we (as knowledgeable professionals or hobbyists) all hope to make the Web a better place by doing our part in publishing documents with semantically rich, valid markup, but the reality is that those documents are rare. It’s important to keep in mind the true nature of the Internet; an open platform for information sharing.
  • XHTML2 has some very good ideas that I hope can become part of the web. However, it’s unrealistic to think that all web authors will switch to an XML-based syntax which demands that browsers stop processing the document on the first error. XML’s draconian policy was an attempt to clean up the web. This was done around 1996 when lots of invalid content entered the web. CSS took a different approach: instead of demanding that content isn’t processed, we defined rules for how to handle the undefined. It’s called “forward-compatible parsing” and means we can add new constructs without breaking the old. So, I don’t think XHTML is a realistic option for the masses. HTML 5 is it.

      Great quote from CSS expert Hakon Wium Lie.
  • @marbux: Of course i disagree with your interop assessment, but I wondered how it is that you’re missing the point. I think you confuse web applications with legacy desktop – client/server application model. And that confusion leads to the mistake of trying to transfer the desktop document model to one that could adequately service advancing web applications.
  •  
    A CMS expert argues for HTML over XHTML, explaining his reasons for switching. Excellent read! He nails the basics. for similar reasons, we moved from ODF to ePUB and then to CDf and finally to the advanced WebKit document model, where wikiWORD will make it's stand.

    See also my comment on the same web page that explains why HTML 5 is NOT it for document exchange between web editing applications. .

    Response to marbux supporting the WebKit layout/document model. Marbux argues that HTML5 is not interoperable, and CSS2 near useless. HTML5 fails regarding the the interop web appplications need. I respond by arguing that the only way to look at web applications is to consider that the browser layout engine is the web application layout engine! Web applications are actually written to the browser layout/document model, OR, to take advantage of browser plug-in capabilities. The interoperability marbux seeks is tied directly to the browser layout engine. In this context, the web format is simply a reflection of that layout engine. If there's an interop problem, it comes from browser madness differentials. The good news is that there are all kinds of efforts to close the browser gap: including WHATWG - HTML5, CSS3, W3C DOM, JavaScript Libraries, Google GWT (Java to JavaScript), Yahoo GUI, and the my favorite; WebKit. The bad news is that the clock is ticking. Microsoft has pulled the trigger and the great migration of MSOffice client/server systems to the MS WebSTack-Mesh architecture has begun. Key to this transition are the WPF-.NET proprietary formats, protocols and interfaces such as XAML, Silverlight, LINQ, and Smart Tags. New business processes are being written, and old legacy desktop bound processes are being transitioned to this emerging platform. The fight for the Open Web is on, with Microsoft threatening to transtion their entire business desktop monopoly to a Web platfomr they own. ~ge~

Microsoft's Next Big Thing; Rich MS Client / MS Cloud of Servers - 0 views

  •  
    CIO Magazine has an extensive interview with Craig Mundie, the man responsible for nailing down the next generation of monopolist profits: "You talk about technology waves. What will be the next big wave? What happens in waves is the shift from one generation of computing platform to the next. That platform gets established by a small number of killer apps. We've been through a number of these major platform shifts, from the mainframe to the minicomputer to the personal computer to adding the Internet as an adjunct platform. We're now trending to the next big platform, which I call "the client plus the cloud."

    That's one thing, not two things. Today, we've got a broadening out of what people call the client. My 16 years here was in large measure about that. And then we introduced the network. The Internet was a place where you had Web content and Web publishing, but other than being delivered on some of those clients, the two things were somewhat divorced.

    The next thing that will emerge is an architecture that allows the application developer to think of the cloud plus the client architecturally as a single thing. In a sense, it is like client/sever computing in the enterprise. It was the homogeneity that existed between some of the facilities at the server and the client end that allowed people to build those applications. We've never had that kind of architectural homogeneity in this cloud-plus-client or Internet-plus-smart-devices world, and I'm predicting that will be the next big thing.

HTML presentation markup deprecated - 0 views

  • Prior to CSS, nearly all of the presentational attributes of HTML documents were contained within the HTML markup; all font colors, background styles, element alignments, borders and sizes had to be explicitly described, often repeatedly, within the HTML. CSS allows authors to move much of that information to a separate stylesheet resulting in considerably simpler HTML markup. Headings (h1 elements), sub-headings (h2), sub-sub-headings (h3), etc., are defined structurally using HTML. In print and on the screen, choice of font, size, color and emphasis for these elements is presentational. Prior to CSS, document authors who wanted to assign such typographic characteristics to, say, all h2 headings had to use the HTML font and other presentational elements for each occurrence of that heading type. The additional presentational markup in the HTML made documents more complex, and generally more difficult to maintain. In CSS, presentation is separated from structure. In print, CSS can define color, font, text alignment, size, borders, spacing, layout and many other typographic characteristics. It can do so independently for on-screen and printed views. CSS also defines non-visual styles such as the speed and emphasis with which text is read out by aural text readers. The W3C now considers the advantages of CSS for defining all aspects of the presentation of HTML pages to be superior to other methods. It has therefore deprecated the use of all the original presentational HTML markup.

The Cover Pages: Alfresco and Joomla Provide Integration Based on CMIS - 0 views

  • Alfresco Software and Joomlatools today announced the first integration based on Content Management Interoperability Services (CMIS). The Alfresco:Joomla! integration module was built using the draft CMIS REST API to allow organizations running Joomla-based web sites to access Alfresco's robust open source content management repository.
  • The integration, built using the CMIS REST API, will enable millions of Joomla web sites to access the powerful back-end content repository services of Alfresco, ensuring security, compliance, and auditability. Users will be able to more effectively manage, preview and track increasing volumes of content and digital assets on collaborative Joomla web sites using Alfresco's content library. Similarly Alfresco users will be able to search, publish, share, download, and edit content directly on Joomla sites.
  • The proposed CMIS standard is currently being advanced by an OASIS technical committee and will enable anyone to develop content applications on open source Alfresco and deploy them on SharePoint, EMC, IBM, or OpenText. In September 2008, Alfresco released the industry's first draft implementation of the CMIS specification. The company has also recently made available the CMIS Developer Toolbox, which includes a working implementation and contains resources to assist developers in the CMIS community to start creating portable content applications, based on the draft specification.

Safe Plurality: Can it be done using OOXML's Markup Compatibility and Extensions mechan... - 0 views

  • During the OOXML standardization proceedings, the ISO particpants felt that there was one particular sub-technology, Markup Compatibility and Extensibility (MCE), that was potentially of such usefulness by other standards, that it was brought out into its own part. It is now IS29500:2009 Part 3: you can download it in its ECMA form here, it only has about 15 pages of substantive text. The particular issue that MCE address is this: what is an application supposed to do when it finds some markup it wasn't programmed to accept? This could be extension elements in some foreign namespace, but it could also be some elements from a known namespace: the case when a document was made against a newer version of the standard than the application.
  •  
    Rick Jelliffe posts a frank view of the OOXML compatibility framework, a document I've studied myself in the past. There is much that is laudable about the framework, but there are also aspects that are troublesome. Jelliffe identifies one red flag item, the freedom for a vendor to "proprietize" OOXML using the MustUnderstand attribute and offers some suggestions for lessening that danger through redrafting of the spec. One issue he does not touch, however, is the Microsoft Open Specification Promise covenant not to sue, a deeply flawed document in terms of anyone implementing OOXML other than Microsoft. Still, there is so much prior art for the OOXML compatibility framework that I doubt any patent reading on it would survive judicial review. E.g., a highly similar framework has been implemented in WordPerfect since version 6.0. and the OOXML framework is remarkably similar to the compatibility framework specified by OASIS OpenDocument 1.0 but subsequently gutted at ISO. The Jelliffe article offers a good overview of factors that must be considered in designing a standard's compatibility framework. For those that go on to read the compatibility framework's specification, keep in mind that in several places the document falsely claims that it is an interoperability framework. It is not. It is a framework designed for one-way transfer of data, not interoperability which involves round-trip 2-way of exchange of data without data loss.

Introducing the Open XML Format External File Converter for 2007 Microsoft Office Syste... - 0 views

  • In other words, revising the Open XML Format converter interfaces by adding new functionality does not require any recompilation of existing clients. This guarantees backward compatibility as these converter interfaces are upgraded.
    • Paul Merrell
       
      But what does it do for forward compatibility? OOXML is a moving interoperabillity target.
  • In addition to allowing converters to override external file formats, the applications allow converters to override OpenDocument Format-related formats (such as .odt). For example, if you specify a converter to be the default converter for .odt, Word 2007 SP2 invokes the specified converter whenever a user tries to open an .odt file from the Windows Shell instead of going through the native load path for Word 2007 SP2.
    • Paul Merrell
       
      How wonderful. Developers can bypass the forthcoming Microsoft native file support for ODF. Perhaps to convert Excel formulas to OpenForumla?
  • Open XML Format converters for Word 2007 SP2, Excel 2007 SP2, or PowerPoint 2007 SP2 are implemented as out-of-process COM servers. Out-of-process converters have the benefit of running in their own process space, which means issues or crashes within converters do not affect the application process space. In addition, out-of-process 32-bit converters can function on 64-bit operating systems in Microsoft Windows on Windows 64-bit (WoW64) mode without the need for converters to be compiled in 64-bit.
    • Paul Merrell
       
      Pretty lame excuses for not documenting the native file support APIs. I.e., the native file supoort APIs already throw "can't open file" error messages for problematic documents without crashing the app. The bit about not needing to recompile converters for 64-bit Windoze is a complete red herring. This is only a benefit if one requires conversion in an external process. It wouldn't be an issue if the native file support APIs were documented and their intermediate formats were the interop targets.
    • Paul Merrell
       
      I.e., one need not recompile the Office app if a supported native format is added. The OpenDocument Foundation and Sun plug-ins for MS Office proved that.
  • ...3 more annotations...
  • To begin developing a converter, you should familiarize yourself with the Open XML standard. For more information, see: Standard ECMA-376: Office Open XML File Formats.
    • Paul Merrell
       
      Note that they specify Ecma 376 rather than ISO/IEC:29500-2008 Office Open XML. So you get to rewrite your converters when Microsoft adds support for the official standard in the next major release of Office.
  • External files are imported into Word 2007 SP2, Excel 2007 SP2, or PowerPoint 2007 SP2 by converting the external file to Open XML Formats. External files are exported from Word 2007 SP2, Excel 2007 SP2, or PowerPoint by converting Open XML Formats to external files. The success of either the import or export conversion depends upon the accurate generation and interpretation of Open XML Formats by the converter.
    • Paul Merrell
       
      Note that this is a process external to the native file support APIs and their intermediate formats. The real APIs apparently will remain obfuscated. Thiis forces others to develop support for Ecma 376 rather than working directly with the native file support APIs. In other words, more incentives for others to target the moving target OOXML rather than the more stable intermediate formats.
  • Summary: Get the details about the interfaces that you need to use to create an Open XML Format External File Converter for the 2007 Microsoft Office system Service Pack 2 (SP2). (16 Printed Pages)

  • One Microsoft data center that is not getting a lot of attention is one the company is building in Chicago, which is the Microsoft's first container-based facility, Chrapaty said, showing a mock-up of a data center container on an 18-wheeler that could be unloaded and added to an existing facility to add capacity.
  • Moreover, Chrapaty said the Chicago data center is the first Microsoft data center to use shipping containers as a primary server packaging and deployment unit. When both phases of the data center are complete, it will total more than 707,000 square feet on a 16-acre site. It will hold hundreds of thousands of servers to deliver on the Microsoft software-plus-services initiative.  The company claims the Chicago facility will be one of the largest data centers in the world and the largest deployment of the use of containers to date.

Expert System Guns for Google with Semantic Search, Advertising - 0 views

  • Would-be Google AdSense rival Expert System launches its Cogito Semantic Advertiser tool, which discerns the meaning and context of words to provide more relevant ads. By leveraging semantic technologies, Expert System joins a cadre of search providers that includes Microsoft-owned Powerset, Hakia, Yedda and Zoomix.
  • The problem is that AdSense relies on keyword frequency but doesn't drill down into the semantics—the meaning in the words. Cogito Semantic Advertiser attempts to go further by using semantic intelligence to analyze the text on each page and ensure that ads are placed appropriately to increase click-through rates.
  • Asher told me Cogito Semantic Advertiser understands content based on four key methodologies: studying the morphology of words; looking at parts of speech; sentence logic, or the reduction of sentences to subject, verb and object; and disambiguation, which in the case of the jaguar story paired with the Jaguar car ad would determine whether or not the text referred to a car or an animal.

Why Mozilla is committed to Gecko as WebKit popularity grows: Page 1 - 0 views

  • One of the primary reasons for the enormous complexity of the Gecko code base is that it aims to provide much more than just an HTML renderer. Mozilla's early goals were extremely ambitious—the original Mozilla application suite included a browser, a complete mail and newsgroup program, a web design tool, and an IRC client. In addition to rendering HTML, Gecko also provides a versatile XML-based user interface rendering framework called XUL that was used extensively in those applications. XUL is still used today to create the Firefox user interface, and it facilitates that browser's support for extensions, which are regarded by many enthusiasts as one of the most valuable features offered by Firefox.
  • XPCOM, a powerful component system
  • Gecko 1.9 uses the cross-platform Cairo rendering framework.
  • ...4 more annotations...
  • reflow algorithm
  • Firefox 4 and replaces XPCOM reference counting with real garbage collection
  • support for some CSS 3 features that are implemented in WebKit.
  • TraceMonkey engine landed in recent nightly builds and will likely be included in 3.1; it massively boosts JavaScript performance
  •  
    The consensus of the developers who are using WebKit is clear: it's an outstanding rendering engine that lends itself to an extremely diverse assortment of practical uses. It is everywhere, and it is gaining traction at a very impressive rate. That traction is causing some developers to question whether Mozilla's Gecko rendering engine is still relevant.

Cover Pages: Open Web Foundation Formed to Support Community Specification Development. - 0 views

  • The formation of the Open Web Foundation (OWF) was announced on July 24, 2008 at the OSCON 2008 Conference. OWF is "applying the open source model of seeing a common pain point and trying to patch the system by creating an 'organizational library' that makes it easier to go through a collaborative specification process and come out of it with clean IPR, leading to faster implementation and adoption.
  • According to the OWF web site: "The Open Web Foundation is an independent non-profit dedicated to the development and protection of open, non-proprietary specifications for web technologies. It is an attempt to create a home for community-driven specifications. Following the open source model similar to the Apache Software Foundation, the foundation is aimed at building a lightweight framework to help communities deal with the legal requirements necessary to create successful and widely adopted specification. The foundation is trying to break the trend of creating separate foundations for each specification, coming out of the realization that we could come together and generalize our efforts... The Open Web Foundation is made up of individuals who believe that the open web is built on technologies that are created in the open by a diversity of contributors, and which free to be used and improved upon without restriction."

FT.com - Sun seeks ray of light in open-source turnround - 0 views

  • Wall Street has all but given up on Jonathan Schwartz.The chief executive of Sun Microsystems has been pushing one of the most drastic turnround strategies Silicon Valley has seen. Yet he now also has to contend with a severe economic downturn, the early stages of which have already exposed Sun's vulnerabilities: its reliance on expensive high-end equipment that does not sell well when times are hard, and its large exposure to the financial services industry.At barely $3 a share, Sun's $2.3bn stock market value is 40 per cent below its book value, and little more than 1 per cent of its value at the start of the decade. The announcement earlier this month of job cuts of up to 18 per cent of Sun's workforce has done little to change investors' minds.

tecosystems » What's a Document? - 0 views

  • To be sure, we should not - must not - try to reframe the traditional definition of a document. For those mainstream folks that will make up the bulk of the user population for the foreseeable future, their definition of what a document is is set, and it would be folly to try and change this. But neither should we let that definition carry forward, tainting more capable formats with the legacy of its limited capabilities. No, we need a new definition or term, I believe. Something more accurately descriptive, and yet non-threatening. Database? Too intimidating, too misleading. Web page? Likewise. Container? I don’t love it.

Google Research Publication: BigTable - 0 views

  • Abstract Bigtable is a distributed storage system for managing structured data that is designed to scale to a very large size: petabytes of data across thousands of commodity servers. Many projects at Google store data in Bigtable, including web indexing, Google Earth, and Google Finance. These applications place very different demands on Bigtable, both in terms of data size (from URLs to web pages to satellite imagery) and latency requirements (from backend bulk processing to real-time data serving). Despite these varied demands, Bigtable has successfully provided a flexible, high-performance solution for all of these Google products. In this paper we describe the simple data model provided by Bigtable, which gives clients dynamic control over data layout and format, and we describe the design and implementation of Bigtable.
