The Battle for the Body Field · An A List Apart Article
"Using this narrative-friendly approach to structured content isn’t a cakewalk ... But the payoff can be dramatic. Richer, more flexible designs can coexist with the demands of multichannel publishing; future design changes can sidestep the laborious process of scrubbing old content blobs; and simpler, streamlined tools can help editors and authors produce better content faster. By combining the best of XML and structured web content, we can make the body field safe for future generations."

A Great Old-Timey Game-Programming Hack - Tom Moertel’s Blog
"We replaced this subroutine with a very special manifestation of insanity that commandeered both stack pointers and used pulls and pushes, and every single available register, to draw tiles upside down and horizontally broken.

"asm.js is a subset of JavaScript, defined with the goal of being easily optimizable and used primarily as a compiler target from languages like C and C++. I've seen some recent online discussions where people appear to misunderstand what those things mean, which motivated me to write this post, where I'll give my perspective on asm.js together with some context and history."

Brian Richards • IE9 Hover Bug Workaround
However, in IE9, when you hover over the elements, the container mysteriously increases in size. And for some reason it grows beneath the scrollbar.

And it keeps increasing in size for each item hovered over. This keeps pushing down all content below the container and destroys the layout of the page.

Light Blue Touchpaper » Blog Archive » A one-line software patent – and a fix
"About 25 years ago, large IT research organizations discovered standards as a gold mine, a vehicle to force users to buy patent licenses, not because the technology is any good, but because it is required for compatibility. This is achieved by writing the standards very carefully such that there is no way to come up with a compatible implementation that does not require a patent license, an art that has been greatly perfected since."
