Microsoft matches two chess engines against one another!
Each turn is limited to 200ms – because the asm.js-optimized engine has a significant performance advantage, it can evaluate more moves per turn and has a substantially higher likelihood of victory. You can adjust the turn length and other variables in the demo to see how they affect the outcome of the game.

An update on Object.observe
From Adam K on the ES-Discuss Mailing List:
Over three years ago, Rafael Weinstein, Erik Arvidsson, and I set out to design and implement what we believed to be the primitive underlying the data-binding system of MDV (“model-driven views”). We prototyped an implementation in a branch of V8, then got agreement from the V8 team to build a real version upstream, while pushing Object.observe (“O.o”) as a part of the upcoming ES7 standard and working with the Polymer team to build their data-binding system on top of O.o.
Three years later, the world has changed in a variety of ways. While other data-binding frameworks (such as Ember and Angular) showed interest, it was difficult to see how they could evolve their existing model to match that of O.o. Polymer rewrote from the ground up for its 1.0 release, and in that rebuilding did not utilize O.o. And React’s processing model, which tries to avoid the mutable state inherent in data-binding systems, has become quite popular on the web.
After much discussion with the parties involved, I plan to withdraw the Object.observe proposal from TC39 (where it currently sits at stage 2 in the ES spec process), and hope to remove support from V8 by the end of the year (the feature is used on 0.0169% of Chrome pageviews, according to chromestatus.com). For developers who have been experimenting with O.o and are seeking a transition path, consider using a polyfill such as https://github.com/MaxArt2501/object-observe or a wrapper library like https://github.com/polymer/observe-js.
We sometimes catch ourselves applying UX in real life; don’t forget there’s a lot we can learn about web UX from real life
This “I’m doing it all the time” idea is how I feel about user experience (UX). I am literally moving through every moment looking at the user experience of every situation. Here are some examples from just this week:
