How browsers get to know you in milliseconds

Behind the scenes of a real-time ad auction on the web.

A small technological marvel occurs on almost every visit to a web page. In the seconds that elapse between the user’s click and the display of the page, an ad auction takes place in which hundreds of bidders gather whatever information they can get on the user, determine which ads are likely to be of interest, place bids, and transmit the winning ad to be placed in the page.

How can all that happen in approximately 100 milliseconds? Let’s explore the timeline and find out what goes on behind the scenes in a modern ad auction. Most of the information I have comes from two companies that handle different stages of the auction: the ad exchange AppNexus and the demand side platform Yashi. Both store critical data in an Aerospike database running on flash to achieve sub-second speeds.

Upward Mobility: Why iBeacons Matter

Get ready for a new generation of position-aware apps

Fans of near field communications payment solutions were, yet again, disappointed when the new batch of iPhones failed to include NFC in their list of features. While it might indeed be nifty for iPhone users to be able to join the Google Wallet revolution, another game-changing technology that Apple has launched has largely gone unnoticed. That would be the iBeacon framework built into iOS7.

iBeacon leverages Bluetooth Low Energy (part of the Bluetooth 4.0 standard), which has been incorporated into iPhones since the iPhone 4S. There are already a ton of applications using Bluetooth LE, notably the gaggle of Kickstarter-funded “find your lost keys” devices that use a small BLE dongle. What’s new is the framework, which allows applications to determine proximity to BLE beacons simply, and even when the app isn’t running. And BLE beacons are relatively cheap, you can get three of them for $99.
