Weekly roundup: consulting in Siena

It has been a busy week in Siena, where I am doing consulting on web development topics. The most effective task in my work has been repairing the test suite of a PHP project and optimizing it for running in 1/5 of the original time.
On the whole, Siena is a beautiful city, with nearly no factories nearby and small enough for me to walk to my workplace through the historical part of city.

Here are my original articles for this week on DZone.
