Has the CSS (or some other setting) been changed recently?

  • I’ve noticed a sudden difference in the way a page is being rendered.
  • It seemed to be resolved by simple editing the page (merely adding an unrelated line).

These types of ‘transient’ changes have also been apparent to me during the last few days that I have been testing TransClusion(s) in that they sometimes appear and sometimes don’t, but that I can generally make them re-appear by simple editing the page (without actually changing anything).

There has been a change, a while back. What exactly are you noticing?

There are two symptoms which appear to be “intermitant” (almost as if editing the page toggles something). (1) I have been testing both internal and external transclusions on my home page. Sometimes the transclued material is rendered correctly and other times, only the source <…> is shown. (2) I have been experimenting a bit with a simple list of TagCloud (nothing more than a “ ; “ delimited list). These lines are also being renedered (almost every other time, and generally at the same time as the transclusion fails) as if the segments of the line had a leading “ “ character (the monospaced style).

In both cases, when the rending appears to fail, making a trival unrealted edit to the page and saving it, yields the desired result.

Thank you for your attention. This is not at all urgent in my opinion. It was merely perplexing and I wanted to know if anyone else was encountering it.

P.S. At present, these errors are apparent to me on my home page.

Hm. You’re homepage looks like a mess. It’s hard to say whether that’s on purpose or not. :)

The W3 validator says that your homepage is not valid XHTML [1]. Before doing anything else, I shall investigate how this is possible and fix it.

Thank you very much.

I agree it looks like a mess (!!), but I’ll leave it alone while you investigate, especially since all that is needed is to perform a trival edit and save it, to see what I wanted it to look like.

For the record, I’m increasingly fond of the bliki and am exploring how to use external transclusions to share MicroBlocks? as broadly as possible. Ideally, this will make it possible to …

  • be much more efficient by having a central block of text that can appear in several contexts.
  • allow a form of “mirroring” to provide redundant co-locations so that a single site failure does not completely make the content unavailable.
    • with effective TransClusion, mirroring may be as simple as an automated FTP process that transfers source to alternat (Read Only) sites.

In a perfect world, this might even interact with the InterMap & Lion’s LocalNames facility to produce even better gains.

P.S. Your Decemeber request for “spark lines” references completely slipped my mind. Sorry about that! I’ll take a look at my library when I get home tonight. If you have a specific interest or context for your interest, I’d be pleased to focus my search as tightly as possible.

Well, the question I want to answer is this: Do we need a markup syntax that facilitates the creation of sparklines? To answer with yes, we first need to answer another question: Are sparklines helpful? To answer with yes, I’d like to see a generalizable example. This examples should illustrate how using sparklines saves time and energy for readers. The example should not include a “real” graph with the same or better information (axes labels and the like), otherwise the sparkline would be redundant. The trade-off for the author (having to at least type all the numbers) should clearly be offset by the benefits for the reader.

In other words, the exact topic for which a sparkline was used, is not important. The particular rhetoric and pedagogic setting are important.

Alex; The following text was taken from JeremyRuston’s “core” TiddlyWiki file. It includes the link to EdwardTufte’s site in which he has quite a few examples and related commentary. In the context of your specific interests, I think they would be helpful to us but I’ll defer posting my reasons for thinking this untill after you’ve had a chance to look at the material. Then , yif you’re still interested, I’d be pleased to enter into a discussion and to do some more research.

Sparklines ( http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=0001OR&topic_id=1 ) were invented by Edward Tufte, author of a number of thoughtful and inspiring books on the presentation of visual information.

Sparklines are described by Tufte as “small, intense, wordlike graphics”. They are designed to be used inline with ordinary text.

Thanks for the link. I see there’s some interesting use when putting several of them side by side. It also seems to me that generating good-looking sparklines requires a good amount of manual intervention in order to be useful. Maybe a specialized site could “standardize” on a format or at least on a small set of formats (eg. financial information). But for a general purpose wiki engine like the one I am interested in, sparklines seem like overkill.

As for the XHTML on your page, I have trouble reproducing the error. When I preview the same wiki text, it looks valid. (I still don’t think it looks “good” that’s a different story.)

Looking at the HTML is not providing me with any clues. Too bad.

Your welcome (for the link).

Thanks for looking at that “Invalid HTML” issue. I’ll just rebuild it in a way that works, now that you done.

I’m not sure if this helps, but I found one bad XHTML I can identify here: [2]. The culprit is the ''Bhe:HwoStyle phrase, which is emphasized, but the emphasis is never closed. It is closed by OddMuse automatically, but only after the parser leaves the table – and it should be closed as soon as the cell boundary is hit. I’m not sure how to fix this or if this is in any way cousing any of the trouble mentioned, but it sure looks like a bug.

Another bad XHTML can be found here [3] due to use of third-level nested list before any second-level nested list was used. We have two nested <ul> tags here, while the inner <ul> should be contained in an <li> tag. Again, no idea on how to fix this.

Wow, Radomir! Thank you for paying such close attention to this.

I probably got careless and failed to close the emphasis (especially within a table). I can’t say that for sure just yet, but I’ll go back and check the prior versions to see where I first introduced that.

As for the heading indents, I have been deliberately over-indenting in a few other wikis and had never noticed any problems, so it never occured to me that this might be a problem in different engines, but I can really see that it could easily be a “bad” practice.

Since I really do want my raw text to be as portable as possible, I’m definitely going to drop that style.

Thanks again.
