This report summarizes the status of the Pringo assessment after a one-day session with

The Pringo system is built on a LAMP configuration (Linux, Apache, MySQL, and
PHP). This combination of technologies is familiar to open-source developers and represents one (perhaps the most common) way to build web sites and web services.
However, just because it is common, doesn’t make it the best (or worst). In contrast, the Passenger platform is built on essentially the polar opposite of LAMP, being Java based and built on Java-related technologies. That doesn’t make one intrinsically better or worse than the other, but they are about as different as they can be in terms of development, deployment, and

The database is MySQL and the OS platform is Linux. Other components and dependencies include
Javascript/AJAX, JQuery, Swish-e, Memcached, BerkeleyDB, mencoder. The system also appears to rely on NFS, but I’m not clear on exactly how or why yet. Once I knew the system was in PHP, I tried to assess how they managed some potential pitfalls. One of the negative tags on PHP is that it is easier to write bad code than it is to write good code. My initial reaction is positive, but with the caveat that some of this discipline comes from force of will, and in particular, the will of Harvard Young. I’ll come back to this point. In terms of code size, Harvard estimated that the server platform represent about 120,000 lines of PHP code. The system uses a modular approach with a “core” and “extensions”. It will require significant more time to get a good understanding of exactly how this works and what is in the “core” and what isn’t. Harvard could not offer any documentation on this and wasn’t able to block diagram it on the whiteboard for me. However, they do have a wiki
(on-line) that I will have to spend time with to see if I can reverse-engineer to get the answer I seek. In practical terms, the Pringo system takes a much different approach to configuration and administration compared to the Passenger system. The Pringo system is lower-level.
It’s more flexible but far more
