Introduction to HTML5
"Charting the Course ... ... to Your Success!" Introduction to HTML5 Course Summary Description HTML5 is not merely an improvement on previous versions, but instead a complete re-engineering of browser-based markup. It transforms HTML from a document description language to an effective client platform for hosting web applications. For the first time developers have native support for creating charts and diagrams, playing audio and video, caching data locally and validating user input. When combined with related standards like CSS3, Web Sockets and Web Workers it is possible to build ‘Rich Web Applications’ that meet modern usability requirements without resorting to proprietary technologies such as Flash and Silverlight. This course enables experienced developers to make use of all the features arriving in HTML5 and related specifications. During the course delegates incrementally build a user interface for a sample web application, making use of all the new features as they are taught. By default the course uses the Dojo Framework to simplify client-side JavaScript and delegates are presented with server-side code written in Spring MVC 3. Other technology combinations are possible if required. Topics Review of the Evolution of HTML Playing Audio and Video Better Support for Data Entry Hosting Clients in HTML5 Support for Drawing Images and Standards Related to HTML5 Diagrams Prerequisites Students should have experience of web application development in a modern environment such as JEE, ASP .NET, Ruby on Rails or Django. They must be very familiar with HTML4 and/or XHTML and the fundamentals of programming in JavaScript. If this is not the case then an additional ‘primer’ day can be added to the delivery. -

Frown: Steven Sinofsky Sent: Friday. May 01, 1998 11:33 PM To: Bob Muglia (Exdnange); Jon D~Vaan Subject: Monday Meeting: Polar Server Issues
Frown: Steven Sinofsky Sent: Friday. May 01, 1998 11:33 PM To: Bob Muglia (Exdnange); Jon D~Vaan Subject: Monday Meeting: Polar server issues I’ve spent the bulk of this week dealing with folks on the issue of Polar (now, unfortunately, Office Server). This mail is my suggestion for moving forward. The current problems are Lhreefold I believe: ¯ As currentty defined, the problem is essentially "produce a SKU". Although people can come up with many product visions around the SKU, the paramount importance is being applied to it being a SKU and it being available. Despite the disagreement ! have with this, I’ll take it as a given.. .... vi ¯ There are too many groups that think they are working on various eements of th~s problem (ODE/Ka , SiteServer/1.onKauf, BackOffice/?, and our tiny teampages project got dragged in as well). As such, the project lacks any formal structure which could reinforce the first goal. A first step would be assigning a traditional triad to work on this (dev mgr, test mgr, gpm). As a note there are a bunch of other teams that think this is their "turf" such as teamserver (which is really duplicated a lot of stuff). The current plans suffer in two dimensions: lack of relevant customer input and a lack of defining and building any substantial asset. Having multiple groups working on this is a real problem since each is approaching it, with limited information, from a very different perspective and the thoughts do not add up. The ODE has sort of evolved into a new variant of a Hessage Queue that doesn’t really use HTTP (as I understand it). -
Picking a Rendering Mode
1245xAPPA 7/17/02 9:26 AM Page 1 PICKING A RENDERING MODE Standing in the middle of yesterday Where it all went wrong—where we made mistakes I’m sorry for the things I forgot to say But it won’t be long until it will be okay —RAINE M AIDA SUPPOSE YOU’VE SPENT A FEW YEARS and several million dollars developing a product that rapidly scans Dewey Decimal numbers on book spines and sends those num- bers to a central database. This enables libraries to keep track of what they physically have on hand. You sell your product to hundreds of libraries all over the country and get a lot of rave reviews. Then one day a large number of libraries decide to abandon Dewey and go to an alternate system, one that allows for more expansion. Many of your customers will be making this switch, but they still want to use your device. They’re willing to pay for an upgrade, and you could provide one, but if you change the product to use this new system, it won’t read the Dewey numbers any- more. That would prevent your other, Dewey-based clients from buying the upgrade and would turn away some new customers. 1245xAPPA 7/17/02 9:26 AM Page 2 2 The simple answer is to build both systems into the device and put a switch on the side so that users can pick which scanning mode they want. This gives you a more flexible device that doesn’t turn away any customers. -
Doctype Switching in Modern Browsers
Thomas Vervik, July 2007 Doctype switching in modern browsers Summary: Some modern browsers have two rendering modes. Quirk mode renders an HTML document like older browsers used to do it, e.g. Netscape 4, Internet Explorer 4 and 5. Standard mode renders a page according to W3C recommendations. Depending on the document type declaration present in the HTML document, the browser will switch into either quirk mode, almost standard or standard mode. If there is no document type declaration present, the browser will switch into quirk mode. This paragraph summaries this article. I will explain how the main browsers on the marked today determine which rendering mode to use when rendering the (x)html documents they receive. I have tested nearly all my assertions in Internet Explorer 6, Firefix 2 and Opera 9.02. The validation is done at the official W3 validation page http://validator.w3.org. Some of my assertions are tested using pages on the net. This is done when testing the media types ‘text/html’ and ‘application/xhtml+xml’with html and xhtml with both legal and illegal syntax. My previous article was full of vague assertions and even things that were directly wrong. This should not be the case in this article where nearly all the assertions are tested. One section I should be humble about is the ‘Doctype dissection’. Finding good sources decribing these in more detail than pages and books just briefly describing their syntax proved hard, but I have done my best and have also described in the text which section I’m certain about and the one I am more uncertain about. -
INSIDE MICROSOFT (Part 2) 2/7/04 2:30 PM
07/15/96 INSIDE MICROSOFT (Part 2) 2/7/04 2:30 PM INSIDE MICROSOFT (Part 2) The untold story of how the Internet forced Bill Gates to reverse course (Continued from Part 1) BABY STEPS. In one breakout group, Allard tangled with Russell Siegelman, who was heading Marvel, the code name for what's now the Microsoft Network online service. Allard argued that instead of being proprietary, Marvel should be based on Web standards. Siegelman held his ground--and won. It was a decision that would later cost millions to reverse. Still, Net progress was made: TCP/IP would be integrated into Win95 and Windows NT, the version of Windows that runs network-server computers. The sales team was told to use the Web to dispense marketing information. The applications group agreed to give Word, the word-processing program, the ability to create Web pages. Next, Gates jumped deeper into the process by devoting much of his April Think Week--a semiannual retreat--to the Internet. His Apr. 16 memo, ``Internet Strategy and Technical Goals,'' contained the first signs of a growing corporate commitment. ``We want to and will invest resources to be a leader in Internet support,'' wrote Gates. It was a first step, albeit a measured one. ``I don't think he knew how much to bet yet,'' says Allard. But board member David F. Marquardt did: He recalls that he was ``amazed'' that Microsoft was putting so little into the Net. ``They weren't in Silicon Valley. When you're here, you feel it all around you,'' says Marquardt, a general partner at Technology Venture Investors in Menlo Park, Calif. -

DOCTYPE Sniffing
06_576429 ch02.qxd 11/18/04 12:28 PM Page 17 2 Document Standards This chapter explores the various options for a document foundation. CSS is a dynamic tool, in that you can use it in more than one type of document, including HTML, XHTML, and XML docu- ments. Each type of document may have several variations, flavors, or degrees of strictness. This chapter describes what’s involved in creating each type. Document standards are something very important to the aspiring CSS web designer. Inclusion of a Document Type Declaration (explained in a moment) and a well-formed document may mean the difference between a splitting, grueling headache and a mark-up document including CSS that works as expected in all the major browsers. Chapter 1 discussed the W3C body, the group assem- bled to decide on web standards. This chapter examines the various documents into which you can incorporate CSS, describing what each document looks like and giving you a few very basic examples of each document in action. The explanation of each topic in the following list is quite lengthy and can easily fill an entire book. This chapter covers only the basics, including ❑ Writing mark-up ❑ Obtaining the required web browsers ❑ Introduction to HTML, XML, and XHTML ❑ Introduction to the Document Type Declaration ❑ DOCTYPECOPYRIGHTED sniffing and how to invoke standards MATERIAL mode ❑ Creating web documents that survive and perpetuate into the foreseeable future Choosing Which Markup Language to Use HTML, XHTML, and XML are all based on SGML, which stands for Standard Generalized Markup Language. SGML is the parent of tag-based languages like HTML, XHTML, and XML, although it is not limited to these three examples.
