Best practices of front end optimization
1. Use DocumentFragment or innerHTML to replace complex elements insertion DOM operation on browser is expensive. Although browser performance is improved much, multiple DOM elements insertion is still expensive and will affect the page load speed.

Scala Macros
This is the home page of project Kepler, an ongoing effort towards bringing compile-time metaprogramming to Scala. Our flavor of macros is reminiscent of Lisp macros, adapted to incorporate type safety and rich syntax.

You can learn more about our vision of metaprogramming from our talks. We propose to enrich Scala ...

Before Python
This morning I had a chat with the students at Google's CAPE program. Since I wrote up what I wanted to say I figured I might as well blog it here. Warning: this is pretty unedited (or else it would never be published :-).
