A Benchmark About Speed of Programming Languages

Yeah, yet another pointless benchmark about speed of programming languages.
Why I call benchmarks pointless is- The speed of a programming language varies widely with use cases.
Language X might be good at executing loops, while language Y might not be.

Additionally, you have to take into account the time spent in developing the programs.
Interpreted languages like PHP, Python, Ruby make a developer’s life very productive and easy, while it may not be for a C or C++ developer.

I am not a fanboy of any language, I just use the language which suits the requirements perfectly.

The languages I’m comparing in this benchmark are C, PHP, Python, Ruby.

Trac and Git: The Right Way

This post is about configuring Trac and Git to work together properly. As you might be knowing, Git is a DVCS – Distributed Version Control System and Trac is a project management system. By default, Trac supports SVN, but there are plugins for Git and Mercurial. I don’t know if there are plugins for other repositories like Bazaar, etc.

In the default configuration in Trac’s Git plugin, the repository is not cached and setting repository_sync_per_request to blank doesn’t stop Trac from syncing repostiories on each request. This is a big performance disadvantage and can big a real big trouble if you have lots of repositories with quite a lot of commits.
