Dating Site Testing and Audit Tools

by David Evans on March 30, 2009 in Startups, Technology

I get a little excited when I think about all the technology required to run dating sites. Here are some new tools I learned about today.

Selenium is a web application testing system.

CRM114 is a system to examine incoming e-mail, system log streams, data files or other data streams, and to sort, filter, or alter the incoming files or data streams according to the user’s wildest desires.

IMVU deploys updates 50 times a day!

Thanks, Guillaume.

He mentions many interesting things like the fact that Facebook uses 25 terabytes and that Facebook doesn’t limit you to 5000 friends for engineering reasons but rather for product reasons. That groups use the same framework as people and groups can have millions of members. There’s a lot of other interesting stuff if you’re interested in the tech.

A friend recently asked a major social net for some of their data/logs for a study he is doing. He asked for 5 gigs or so, they said that was about 45 minutes of use or something like that.
