Faking Data (Building a Real-looking Demo Account) Philip Sharp @philipsharp Clearspring / AddThis DC PHP July 13, 2011

Screenshots are useful...

Screenshots are not a demo. Nor do they keep themselves up-to-date. (The same thing goes for videos.)

Neither is a free trial.

We collect data. People want to see how it looks up-front. (We're not all Google. GA doesn't need a demo.)

A good demo requires good data. (Chartbeat is lucky. But we can't all show Fred Wilson's data.)

Obfuscate if you can. demoPayees = [“Joe's Widgets”, ” ACME Explosives”, “ Frank's Fish Fry”] transaction = { “ datetime”: “2011-07-13 18:52:22” “ payee”: “Churchkey”, “ ammount”: 145.23 } transaction.payee = demoPayees[rand(0,2)];

Make your own if you can. { “ username”: “frodo” “ name”: “Frodo Baggins” rings: 1 }

Some data doesn't cooperate.

foreach

$shareMagnifier = $countrySharePercentage * $serviceSharePercentage * $browserSharePercentage / 100000; $combinationTarget = $domain['target'] / count($domain['urls']) / count($domain['referers']) / count($domain['keywords']); $dayMultiplier = (($daysOfData - $day) / 100) + 1; $combinationShares[-$day] = floor(rand(1,100) * $shareMagnifier * $dayMultiplier * ($combinationTarget / 50));

The Result

Using It Demo Accounts Demo Profiles

OOP to the rescue. /** * Hydra Package API demo wrapper * * @author philip * @requires Zend Framework */ class AT_Hydra_Package_Service_Demo extends AT_Hydra_Package_Service { … } $dataModel->setService(new AT_Hydra_Package_Service_Demo());

But wait, there's more.

This...

Looks like...

$radian = ($minute / 1440) * 2 * M_PI + (1.25 * M_PI); $sin = sin($radian) + 1.05; $shares = round(rand(1,100) * $sin * $shareMagnifier * $combinationTarget);

0.00000001 * [Just about anything] is a really small number
