A New Experimental Feature: scoped stylesheets
Chromium recently implemented a new feature from HTML5: scoped stylesheets, aka. <style scoped>. A web author can limit style rules to only apply to a part of a page by setting the ‘scoped’ attribute on a <style> element that is the direct child of the root element of the subtree you want the styles to be applied to. This limits the styles to affect just the element that is the parent of the <style> element and all of its descendants. Example Here’s a...

Notes on Programming in C
Introduction Kernighan and Plauger's The Elements of Programming Style was an important and rightly influential book. But sometimes I feel its concise rules were taken as a cookbook approach to good style instead of the succinct expression of a philosophy they were meant to be. If the book claims that variable names should be chosen meaningfully, doesn't it then follow that variables whose names are small essays on their use are even better? Isn't MaximumV...
