  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...

  A Toast to C

At Cloudmetrx, we use a lot of C. So given the recent passing of UNIX legend Dennis Ritchie, the creator of the C language, we think a toast to C is only fitting.Our extensive reliance on C is especially unusual considering the other languages in our stack – Clojure, Node.js, and other hipster platforms. We aren't predisposed to using older, "venerated" technologies simply because they're older and venerated. But when it comes to high-performant computation, there's just nothing like C. S...

  Kodiak PHP can run PHP codes offline on iPad

In the eyes of the vast majority of application developers, iPad is the terminal equipment for running code, rather than the tool used to write code. However, there are some applications developers finding iPad's potential to develop a wide variety of programming applications with some applications, such as Diet Coda, Koder, Gusto and so on. The family of applications for writing applications has added a new member -  Kodiak PHP. This application runs on iPad, it can be used to develop PHP ...

  Round Peg, Square Hole: How to Know If a Developer is a Good Fit for Your Team

Over the last few months, we have been recruiting developers, and we’ve started to get a sense for the type of developer who is a good fit for our team.  These attributes probably apply for developers at most web startups, so I wanted to share them with you. Before I get into it, the most important thing to know is that technical skill is a threshold requirement.  The assumption is that any person who is a fit for our team will have the relevant technical experience t...

  Why I love Common Lisp and hate Java

“Common what?” is a common reply I get when I mention Common Lisp. Perhaps rightly so, since Common Lisp is not all that common these days. Developed in the sixties, it is one of the oldest programming languages out there. In its heydays it was used mostly for Artificial Intelligence research at MIT, Stanford, Carnegie Mellon and the like, and therefore has a lingering association with AI. People not in AI shy away from Lisp. Common Lisp is a powerful and versatile program...

  Permutation implementation in Java

Permutation is a very basic and important mathematic concept we learned in school. It has very practical applications in real world. For example, in football. In simple, permutation describes all possible ways of doing something. For example, there are six permutations of the set {1,2,3}, namely: (1,2,3), (1,3,2), (2,1,3), (2,3,1), (3,1,2), and (3,2,1). In general, for n items, there are n! number of permutations to arrange these items. How can we implement this algorithm in programming programm...

  Learning Ruby and Ruby vs Lisp

The company I work for has a lot of legacy Ruby code, and as Ruby has become kind of a mainstream language, I decided to get a book about it and learn how it works. As my learning resource, I chose The Ruby Programming language by David Flanagan and Yukihiro Matsumoto as that receives great customer reviews, covers Ruby 1.8.7 and 1.9 and is authoritative because the language creator is one of the authors. The book makes a good read in general. There are plen...

  "Programmer" is an Overgeneralization

"Beware of bugs in the above code; I have only proved it correct, not tried it." - Donald Knuth Earlier today, I came across a post during a google-fu session that claimed that no one should use the C++ standard library function make_heap, because almost nobody uses it correctly. I immediately started mentally ranting about how utterly ridiculous this claim is, because anyone whose gone to a basic algorithm class would know how to properly use make_heap. Then I started thinking about all the ...
