Many things in life are simpler when you only need to be within 5%: Pi is pretty much 3 Water weighs pretty much 8 pounds a gallon A quart is pretty much a liter (and a gallon, 4 liters) A year has pretty much 360 days, and pretty much 31 million seconds The speed of…

I see from the system requirements that Leopard requires an “866” Mhz processor. Is this a hard limit, or just an advisory? My first Mac–the one I wrote the book on–is a lowly 800 Mhz. box. Is it worth trying to upgrade it? -m
The more I look at RDFa, the more I like it. But still it doesn’t help with the pain-point of namespaces, specifically of unmemorable URLs all over the place and qnames (or CURIEs) in content. Does GRDDL offer a way out? Could, for instance, the namespace name for Dublin Core metadata be assigned to the…
In researching for an XPath 2.0 implementation, I ran across this curious document from the W3C. Despite being labeled a Working Draft (as opposed to a Note), it appears to be a one-shot document with no future hope for updates or enhancements. In short, it outlines several options for the first stage or two of…
If you’re in the South Bay and like mead, you need to check this out. -m
Depending on who’s asking and who’s answering, W3C technologies take 5 to 10 years to get a strong foothold. Well, we’re now in the home stretch for the 5th anniversary of XForms Essentials, which was published in 2003. In past conferences, XForms coverage has been maybe a low-key tutorial, a few day sessions, and hallway…
I didn’t get to do much for Yahoo Hack Day, but I did get to help a coworker a teeny bit with an implementation of Y! Search for social web sites, including Facebook. There could be some interesting repercussions from that, so I won’t say more now. But what did surprise me is how many…
As widely reported by now, the final schedule for XML 2007 this December in Boston is up. All I have to add is the suggestion of careful attention to the Tuesday program at 4:00. :) If you can’t wait, some technical details are forthcoming in this space. That is all. -m
I’ll be doing some experimenting around here over maybe the next week or two. Specifically, setting up hAtom within these pages. Watch for falling debris and report any unusual observations. -m
Let’s see how many downstream pieces of software trip over this post… Do greater-than and less-than signs need to be escaped in XML? Conventional wisdom has it that less-than signs always do, since that character starts a fresh “tag”, but greater-than signs are safe. Wrong. There is a particular sequence, namely ]]> , not allowed…
It’s a common need to parse space-separated attribute values from XPath/XSLT 1.0, usually @class or @rel. One common (but incorrect) technique is simple equality test, as in {@class=”vcard”}. This is wrong, since the value can still match and still have other literal values, like “foo vcard” or “vcard foo” or ” foo vcard bar “….
