  Regex vs IndexOf in Java.

Overview The author of these articles Are C# .Net Regular Expressions Fast Enough for You? and .Net Regex: Can Regular Expression Parsing be Faster than XmlDocument or Linq to Xml? recently pointed out to me that he had found that Regular expressions were at least as fast or faster than the alternatives in C#. However it has been my experience that regular expressions in Java were slower. It is hard for me to say why this might be different in Java and C# or even if these are fair compari...

  How To Find Link Prospects Without Using Google

I’m obsessed with Google. (I mean, you kind of have to be if you’re in this industry.) But sometimes, you need a break from the hand that feeds. There’s no denying the power of advanced search queries, but you’d be surprised how many other and different prospects you can find without using the search engine at all. Curated Lists OK, I lied. You do have to use Google for this, but not nearly in the capacity you would with normal searches. With lists, you have less ...

Have you noticed that Facebook CEO Mark Zuckerberg always wears the same thing every day when he appears in the public? A grey t-shirt which is now a symbol of Mark Zuckerberg. The reason why he wears the same thing every day is "I want to clear my life to make it that I have to make as few decisions as possible about anything except how to best serve this community" as what he said in an in-person public Q&A at the Facebook HQ in Menlo Park where he answered questions from people around th...

  Easy Parallel Processing in PHP

The proliferation of multicore CPUs and the inability of our learned CPU vendors to squeeze many more GHz into their designs means that often the only way to get additional performance is by writing clever parallel software. One problem we were having is that some of our batch processing jobs were taking too long to run. In order to speed the processing, we tried to split the processing file into half, and let a separate PHP process run each job. Given that we were using a dual core serv...

  What I learned interviewing with Google

Over the last few weeks I’ve been interviewing with Google for a job doing primarily JavaScript development. I didn’t end up getting the job but I thought I would share the process of interviewing for Google as it was both very exciting and a humbling experience. I can’t reveal everything as I’m under a few NDAs. I’m not going to mention the products or teams that I was interviewing for but you may be able to guess. For those that don’t know me, IÃ...

  C Preprocessor Hell

Lisp programmers should stop reading right now because they'll likely suffer severe injury of the jaw muscles as they laugh themselves silly at how hard it is to do some things in C. The C language has a pre-processor (typically called cpp) that is both infuriating and powerful. How powerful is usually best described as 'just too little' and it has happened more than once that I found myself almost - but not quite - able to do what I wanted to do. The frustration can run very deep at ti...
