    I have been working at Simplex full-time (More than 5 years)

    Pros

    Developers get to take ownership of their projects and can get recognized for their contributions. The company has a very flat hierarchy and offers a lot of opportunities for developers to work on interesting projects where code latency really matters. Most of the developers at the company are genuine hackers and are passionate about their work. Also the benefits and compensation are great.

    Cons

    Like most jobs in this industry, it can be stressful at times but that keeps things interesting. Being a smaller company, there is limited formal training for new hires, but you learn by performing smaller development tasks and working your way up. There are no separate QA or operations teams. As a result the developers are responsible for those duties as well.

    How does grep run so fast?

    To add to Steve's excellent answer. It may not be widely known but grep is almost always when grepping for a pattern-string than a short one, because in a longer pattern, Boyer-Moore can skip forward in longer strides to achieve even better speeds: Example: # after running these twice to ensure apples-to-apples comparison # (everything is in the buffer cache) $ time grep -c 'tg=f_c' 20140910.log 28 0.168u 0.068s 0:00.26 $ time grep -c ' /cc/merchant.json tg=f_c' 20140910.log 28 0.100u 0.056s 0:00.17 The longer form is 35% faster!
