No matter what great leaps forward the Internet Explorer team make from now on, the majority of developers won’t use them and the majority of users won’t see them. By doing this the Internet Explorer team may have created their own backwater, shot themselves in the foot and left themselves for dead.
If you want CSS rules to apply to unknown elements in IE, you just have to do document.createElement(elementName). This somehow lets the CSS engine know that elements with that name exist.

RSS Duplicate Detection. “Detecting duplicate items in an RSS feed is something of a black art”. I hadn’t realised quite how involved such a basic function of an aggregator could be. # 8:11 pm
<META HTTP-EQUIV=“X-BALL-CHAIN”>. Mozilla hacker Robert O’Callahan discusses the technical implications of freezing copies of older rendering engines, including the increased footprint and the terrifying prospect of documents in different rendering modes communicating through iframes and the DOM. # 6:55 pm
Broken. Jeremy highlights the fly in the ointment: if you want IE 8 to behave like IE 8 (and not pretend to be IE 7), you HAVE to include the X-UA-Compatible header. # 6:42 pm
The versioning switch is not a browser detect. PPK: “In other words, the versioning switch does not have any of the negative effects of a browser detect.” # 4:34 pm
Like DOCTYPE switching did in 2000, version targeting negates the vendor argument that existing behaviors can’t be changed for fear of breaking web sites. If IE8 botches its implementation of some CSS property or DOM method, the mistake can be fixed in IE9 without breaking sites developed in the IE8 era. This actually makes browser vendors more susceptible to pressure to fix their bugs, and less fearful of doing so.

Beyond DOCTYPE: Web Standards, Forward Compatibility, and IE8. This has huge implications for client-side web developers: IE 8 will include the ability to mark a page as “tested and compatible with the IE7 rendering engine” using an X-UA-Compatible HTTP header or http-equiv meta element. It’s already attracting a heated debate in the attached discussion. # 12:40 pm
World’s ugliest Django app. Brilliant hack from Paul Bissex: a self-contained Django application in 70 lines of code which shows off some internals trickery and makes use of a bunch of handy django.contrib packages. # 1:34 am
Heavier than Air. Charles Miller points out that every time Apple breaks the mold with a new product (the iPod, the iPod Mini, the iMac and now the MacBook Air) they lose in feature matrix comparisons but win in the marketplace. # 1:32 am
