StringBuffer vs. StringBuilder performance comparison
Even if the StringBuilder was around for a while now, many people still use StringBuffer in single threaded applications. The main difference is stated in the StringBuffer comments:
“As of release JDK 5, this class has been supplemented with an equivalent class designed for use by a single thread, {StringBuilder}. The StringBuilder class should generally be used in preference to this one, as it supports all of the same operations but it is faster, as it performs no synchronization.” (more…)

The “tech lead” role can be treacherous at times. While the name implies “leadership“, most of the times it doesn’t come with implied authority like a manager role for example.

In order to successfully help a project from this position one has to navigate through narrow and convoluted straits.
