An obese Gina Lollobrigida

Things too good to pass up:

The Life Issue I checked out featured some fun ads, including one for a portable TV that looked like a tank, and one in the back by the American Petroleum Industry about the cheap cost of gas. The issue also featured stories of the time, including the recovery of a kitten washed out by a ocean wave, and the explosion of the world’s fastest seaplane.

The main focus of the issue, though, was on a story and photos of the beautiful Gina Lollobrigida, still considered one of the sexiest women of all time. The magazine covered her extensive wardrobe, and described how she created a catalog of our her outfits in order to make it simpler for her maid to fetch the correct one. She even drew pencil sketches of the outfits, annotating them with numbers so she could call and ask for the outfit by number.

The magazine described Ms. Lollobrigida as a perfect size 12. I choked at that, because in a recent discussion about “plus-size” models, several people accused a size 12 model of being “obese”. Something for James Fallows to consider in his ongoing series about obesity and America.

Site problems, HTML5, and LC Realities

Well, that was exciting. I wasn’t sure what was happening with my sites, since Drupal throws up a maintenance page automatically when it can’t get a database connection. My ISP is still investigating what caused the problems.

In the meantime, the WhatWG IRC log is interesting reading today, including the following quote about HTML5 and Last Call, from Philip:

AryehGregor: Hixie, are we still scheduled for October Last Call?  
Philip: If there's a delay, we can just redefine October 
           to match the reality of the spec's status

So there you go, if someone asks whether HTML5 will make Last Call in the next few weeks, you can answer, Yes—secure in the knowledge that it’s always October, somewhere.

Just close the browser

 

Years ago, when I lived in San Francisco, I was sitting in my favorite chair one day, listening to music and typing into my laptop when the door to my apartment opened. A man enters, sees me and stops, half in, half out. He stares at me, I stare at him, waiting for him to say something along the lines of “Oh, excuse me! Wrong door!”

When he continues to stare and look around the apartment in confusion, I ask, “Can I help you?”, being sure to put a little ‘you’ve walked into my home, bud, and what if I had been nude’ tone into my voice.

He starts laughing and says, “I’ve come to the wrong floor! I live on the second floor and must have got off on the wrong floor. I live in 222!”

Sounds reasonable. Easy mistake. Just shut the door on your way out.

“I was so surprised. I couldn’t figure out who you were.”

Well, cool. Please leave now.

“How funny! You must have really been surprised, too.”

WHAT THE HELL DO I NEED TO DO TO GET YOU TO GO!

I got up and walked towards the door and the guy still isn’t leaving. Friendly, not harmful at all — just chattering away. Being a polite soul, I respond to his chatter. Yes, funny coincidence. Yes, I do sometimes forget to lock my door when I bring groceries in. And, yes, weather has been nice…now move your butt outside my door!

After I herded him out, and just as I’m closing the door he calls back, “Well, nice meeting you!”

I locked the door and started to walk away. Stopped. Turned back and threw the dead bolt.

We are a society that is, above all, polite. We have raised courtesy to an art form, honing it into fine-edged usefulnes. Our words become knives as we fight a duel called “conversation” — victor and victim equally bloodied. We circle and stab, and then commiserate with the pain, apologize for the sting.

We pommel each other with argument and viewpoint, all the while debating the finer points of etiquette. We hammer at each other with opinion; we blast most eloquently, and always with the highest regard, the deepest sincerity.

We hold mirrors up to show others their flaws, only to find that the silver has flaked off, the glass is transparent.

You know what I like about being online? If you read something you don’t like, or something that irritates you, or a piece of self-righteous garbage, you can close the browser and it’s gone. You don’t have to be polite. You don’t have to read, react, respond.

Just close the browser.

The HTML5 silly season

Cynthia Shelly released an alternative proposed HTML5 draft that addresses the table summary attribute. The responses to her draft have been less than edifying, and demonstrate rather succinctly most things wrong with the HTML WG.

If you follow along in the thread, you’ll see Apple’s Maciej and IBM’s Sam Ruby go back and forth on protocol, a discussion Maciej ends with a suggestion to focus on salvaging a “proposal” from the work. The thing is, providing alternative text in a specification is the proposal, the only that is deemed acceptable to the HTML WG. At least, that’s what we’ve been told in the past.

Not that Cynthia is demanding that the text be used as is. This was a suggested text, addressing how summary could be discussed in the HTML5 specification, in order to ensure proper use. The proposal also removes summary from the obsolete list. Cynthia proposed this alternative text in order to generate discussion, leading to its refinement; to encourage team effort. Simple enough to understand, but then we’re subjected to the typical Ian Hickson disingenuous approach to anything he disagrees with: pretend he doesn’t understand what the proposal is all about.

I couldn’t find any description of what problem this proposal is trying to solve. Could you point me to the description of the issue that is being resolved here? Why is the text currently in the HTML5 spec not considered acceptable middle ground?

It is difficult to evaluate proposals without understanding what problems they are trying to solve.

Incidentally, I believe the process that we are supposed to be following these days is that when there is a problem in the spec, a bug should be filed describing the problem, so that the issue can be tracked. If you could file a bug (or point me to the relevant bug if one is already filed), that would be very helpful.

(At this point I would like to inform my readers: everyone can file a bug, you don’t have to be a member of any W3C organization to do so.)

So, HTML WG team members are told by one of the HTML WG Chairs to provide alternative specification text, while the HTML5 author countermands such a recommendation, with a note that we file bugs, instead. Seriously, I keep expecting the third stooge to enter the scene, stage left.

And he does. The author of validator.nu, worker extraordinaire for Mozilla, Henri Sivonen, puts on his court jester cap to derail even the potential for worthwhile discussion:

Further quotes are from the proposed text--not from Maciej:
> Summary is one way to provide explanatory information about tables  
> that consist of more than just a grid of cells with headers in the  
> first row and headers in the first column.
>
Does this intend to say that using @summary is categorically  
unnecessary when headers appear in the first column and/or first row?  
If so, it would be good to make this clear.
> Such explanatory information should introduce the purpose of the  
> table,
>
Shouldn't the purpose be stated to all readers?
> outline its basic cell structure,
>
Shouldn't this be generated by the AT from the table model?
> The information provided by the summary is needed by users who  
> cannot see the table, but would usually be redundant for those who  
> can.
>
This sentence sticks out as non-spec-like. It doesn't state a  
requirement, so it looks odd in the middle of a paragraph that states  
requirements.
> This must be done in a way that is associated with the table via  
> markup, such that user agents and assistive technology can  
> programmatically determine the relationship.
>
This sentence could make sense in WCAG-like contexts where things are  
defined in terms of what available software happens to support. It  
doesn't make sense in a spec that defines what software must support.  
(Furthermore, "programmatically determine" is a special term from  
other specs but isn't defined as part of the special vocabulary of the  
HTML5 spec.)

The proposed text seems to imply (in the edits done on examples) that  
having the explanation in a paragraph preceding the table isn't  
sufficient without an explicit aria-describedby link (misspelled in  
the proposed text as aria-described-by). Why is that not sufficient?
> When using summary in combination with another technique, authors  
> must not use the duplicate text, but instead use summary for the  
> parts of the description that are only useful to users who cannot  
> see the table.
>
What about duplicating information that AT should be able to voice  
based on the table model?
> <table summary="The table is divided into six columns: Map number,  
> Date, Area or stream with flooding, Reported deaths, Approximate  
> costs (uninflated), and Comments. The rows are grouped by flood  
> types into six subcategories: Regional flood, Flash flood, Ice-jam  
> flood, Storm-surge flood, Dam-failure flood and Mudflow flood." 
>
In this case, the first sentence clearly duplicates information that  
are trivially programmatically determinable by the AT from the table  
model (given proper <th> markup). As for the second sentence, I think  
it would be worth investigating if the salient content of the second  
sentence is also realistically programmatically determinable from the  
table model. On the face of it, discovering the content of the second  
sentence from the table model doesn't seem like an overly hard  
software problem.

So, the text of the proposal that Cynthia provides is addressed to humans, which Henri rejects, because Cynthia’s text should be addressed to machines. She discusses declarative markup, and addresses this discussion to people, in order to ensure that the summary attribute is properly used by web page authors and designers. Henri reduces the whole to algorithms, care and feeding of.

This is a perfect lead in to another discussion about HTML5 taking place elsewhere, in the W3C TAG, which has ultimate responsibility for ensuring the many specifications such as HTML5 work in a complementary manner for the web. The focus of the TAG at this time is detailing issues this group has with the current HTML5 draft, a discussion generating a typically mature level of discussion in the WhatWG IRC channel.

One such issue, as I have noted, as others have noted, is the fact that the specification is given in algorithmic terms, rather than as declarative text—based on discussions of a Document Object Model (DOM) with HTML markup given as a distant secondary item (barely covered, and leaving ripples of confusion in its wake).

The current rendering of the specification is considered more precise for the browser companies, for Mozilla, Google, Microsoft, Opera, and Apple, but the precision completely obfuscates the information needed by thousands, perhaps millions of web page authors and designers.

In the past, the main specification would be about the markup, with a secondary document describing the DOM. And oddly enough, this has worked, if we can believe the evidence of our eyes. Evidently, this wasn’t to the taste of the browser companies, who believe that it is more important that their needs be met, rather than the needs of the thousands, perhaps millions of web page authors and designers.

In addition, rather than leave many decisions up to the implementors of the specification, the editor’s draft seeks to detail, in minute detail, how everything is to be handled by implementors. Precise, very precise. Good luck with the 50,000 or so test cases.

So far, I have submitted three HTML5 bugs:

  1. When Web Workers was removed from the spec, orphan references were left – clean up is needed
  2. To remove the Microdata section, as it isn’t necessary, nor widely supported
  3. To allow other namespaced elements in SVG, since the use of these elements is valid within SVG

And I just submitted a bug for table summary. There will be others. Too bad I’m not one of the elite.

SVGWeb and the XML Issue

I’ve been playing around with SVGWeb, liking the library more over time. I re-created the SVG in HTML5 example, and at first it didn’t work. I thought it could be because SVGWeb couldn’t manage the metadata element, but when I loaded the page in Firefox, with Firebug, I found that the SVG/XML still had the bugs I inserted to test whether the Firefox nightly would correct the HTML-enabled errors—the example still had an unquoted attribute, and elements with missing tag ends. In fact, I got XML error messages within the Firebug console exactly I would expect such errors if I loaded the SVG directly in the browser.

SVGWeb manages SVG for browsers that can handle SVG by creating an XML document of the SVG. You can tell, because if you click the circle with the new example, all of the namespaces for the RDF/XML elements are handled properly, even though the page is parsed as HTML. To me, this is the way SVG should be handled in a document, whether the document is parsed as HTML or as XHTML. This pretense that SVG is not XML when its in HTML is patently absurd. It doesn’t map to anything that exists in the real world.

The SVGWeb library is a wonderful tool, but I would really prefer all that functionality be embedded directly in the browser handling of SVG in HTML. I read the past discussions on SVG in HTML, about how trying to maintain the XML nature of SVG within HTML would require “exceptional parsing rules”, or something of that nature. It seems, though, that SVGWeb is managing the issue just fine, and doing so without having to make one change to any parser for any browser. SVGWeb works by generating a SVG document and inserting the document into the DOM (if the browser supports SVG). Technically, this is little different than what happens for inline SVG in XHTML now. So why is this a perfectly acceptable approach when using script, but not acceptable when not using script?

I’m also aware of the discussions about mixing content, such as SVG in MathML, and MathML in SVG, and HTML5 in both. I made another copy of the example, this time inserting an HTML5 paragraph element into the SVG. Since the syntax I used was proper XML (no unquoted attributes, closing paragraph), it parsed without an error, but the paragraph didn’t display. Of course not, because there is no paragraph element within SVG, and the SVG is treated as an SVG document, not an SVG in HTML document. The thing is, though: the paragraph wouldn’t do anything in SVG within an XHTML document today.

However, returning to the example I linked earlier, I did insert HTML into the SVG using the SVG foreignObject element, with proper syntax, and as you can see, the HTML does display correctly. In fact, if you scroll down, I also created a second SVG element, this time with MathML as the foreignObject contents, which renders fine in Firefox, and partially everywhere else, depending on MathML support.

All of this works, and works well, when using SVGWeb. You can even access namespaced Rdf/XML elements in the XML, using the proper namespace functionality, but the page still validate using Validator.nu. All of the portentous grumblings about the horrors of mixing HTML and XML just don’t ring as ominously when one can see that, contrary to the dire warnings, and tales of potential woe, the two can mix. Unfortunately, the only way to mix the two, now, is to be dependent on a Google JavaScript library. Don’t get me wrong: I’m grateful for the library. So grateful, in fact, that I don’t recommend the use of SVG inline with HTML unless you use this library.

I just don’t like being dependent on JavaScript for that which should be and can be, natively supported in a browser. This approach requires library intercession for all instances of SVG use, which means the SVG markup won’t be accessible to server-side applications that disregard the script element. This JavaScript dependency also means the SVG won’t be visible if scripting is disabled, even though SVG does not require scripting support. When scripting is enabled, the approach is still inherently inaccessible.

These are the two choices facing us with SVG in HTML: SVG/XML treated as HTML, and all the problems this causes; or SVG/XML treated as XML, but requiring JavaScript.
