Perf4J 0.9.7 -
Perf4J is a set of utilities for calculating and displaying perfomance statistics for Java code. For developers who are familiar with logging frameworks such as log4j or java.util.logging, an analogy helps to describe Perf4J: Perf4J is to System.currentTimeMillis() as log4j is to System.out.println()
With jQuery 1.3.2 out the door I've been looking for more ways to profile and optimize jQuery. Previously I did a survey of jQuery-using sites to figure out which selectors they were using. This led to the construction of the new Sizzle Selector Engine which targeted those selectors for improvement. Additionally, I constructed a deep profiling plugin for jQuery which helped to spot methods that were taking a long time to run in live jQuery sites. This helped bring about the improvements in jQuery 1.2.6, 1.3, and 1.3.2.

In our company, code reviews play an integral part in the development process for making quality software. We opt for a mentor style approach with Wufoo, where a developer works on a segment for a period of time and then passes it up to a more experienced developer for review. We really like this approach because it means more developers become familiar with the foundation of different code level services. More importantly, they act as an additional safeguard against security holes, memory leaks, poor queries and heavy file structures. Unfortunately, these reviews are also very time consuming and in a small team can sometimes be an inconvenience to the reviewer — another developer with their own todo list to accomplish.
