<p><strong><a href="http://developers.facebook.com/news.php?blog=1&amp;story=358">HipHop for PHP: Move Fast</a></strong></p> Facebook have open-sourced their internally developed PHP to C++ compiler. They serve 400 billion PHP pages a month (that’s more than 150,000 a second) so any performance improvement dramatically reduces their hardware costs, and HipHop drops the CPU usage on their web servers by an average of 50%. “We are serving over 90% of our Web traffic using HipHop, all only six months after deployment”. <p>Tags: <a href="https://simonwillison.net/tags/facebook">facebook</a>, <a href="https://simonwillison.net/tags/hiphop">hiphop</a>, <a href="https://simonwillison.net/tags/optimisation">optimisation</a>, <a href="https://simonwillison.net/tags/performance">performance</a>, <a href="https://simonwillison.net/tags/php">php</a>, <a href="https://simonwillison.net/tags/traffic">traffic</a></p>

<p><strong><a href="http://travel.capitalradio.co.uk/">Capital FM London Traffic Map</a></strong></p> We launched this today at GCap (née Global Radio). I’m particularly impressed with how well the team handled clustering the traffic cameras on the Google map. <p>Tags: <a href="https://simonwillison.net/tags/capitalfm">capitalfm</a>, <a href="https://simonwillison.net/tags/clustering">clustering</a>, <a href="https://simonwillison.net/tags/gcap">gcap</a>, <a href="https://simonwillison.net/tags/google-maps">google-maps</a>, <a href="https://simonwillison.net/tags/london">london</a>, <a href="https://simonwillison.net/tags/traffic">traffic</a></p>
