  Understanding GoLang interface

If goroutine and channel are considered as the foundation for GoLang concurrency, interface would be the key for data types in GoLang. In practical Go programming, almost all data types are built/used around interfaces, interface is the core of GoLang data structures. Go is not a typical OOP language, it has no class and inheritance concept syntactically. But it doesn't mean that there cannot be polymorphism in GoLang. Because of interface, it achieves the same polymorphism effect as in C++, tho...

  Why are column oriented databases so much faster than row oriented databases?

I have been playing around with Hybrid Word Aligned Bitmaps for a few weeks now, and they turn out to be a rather remarkable data structure.  I believe that they are utilized extensively in modern column oriented databases such as Vertica and MonetDB. Essentially HWABs are a data structure that allows you to represent a sparse bitmap (series of 0's and 1's) really efficiently in memory.  The key trick here is the use of run length encoding to compress the bitmap into fe...

  Handling Plugins In PHP

A common problem that developers face when building applications is how to allow the application to be "plug-able" at runtime.  Meaning, to allow non-core code to modify the way an application is processed at runtime.  There are a lot of different ways that this can be done, and lots of examples of it in real life.  Over a year ago, I wrote a StackOverflow Answer on this topic.  However, I think it deserves another look.  So let's look at some patterns and common im...

  The Balanced Developer

In preparation for a recent team offsite, I spent some time thinking about what I hold dear as a software developer. One idea I kept coming back to is the notion of balance. I see balance manifesting itself several ways in the work of a successful developer, some of which follow.Speed Versus QualityThe most obvious example is the balance of development speed and quality. When building software, it’s never a good idea to write code as fast as possible without any attention toward maintaina...
