Odds are, you don’t use a functional programming language every day. You probably aren’t getting paid to write code in Scala, Haskell, Erlang, F#, or a Lisp Dialect. The vast majority of people in the industry use OO languages like Python, Ruby, Java or C#–and they’re happy with them. Sure, they might occasionally use a “functional feature” like “blocks” now and then, but they aren’t writing functional code.And yet, for years we’ve been told that functional languages are awesome. I still remember how confused I was when I first ...

A good code editor will save developers much work. It can help developers find syntax errors easily through code highlight capability. It also makes the code more readable and maintainable through the indentation.

Since I'm seeing so many hits for this page, and since most of you are developers, I thought it might be worth trying to do a little blatant recruiting If you are an exceptional, passionate front end developer (HTML, CSS, JS) and you want to work in an awesome SCRUM team at a huge multinational company in the South of the Netherlands, please drop me a line (DM my Twitter account).There are also opportunities for developers (front and/or back end) and UNIX gurus at another brilliant company (Competa) in the Randstad. Basically, if you love tech and you're looking for work in Holland, ...

When I browse the recruiting information in the website, I always see the following requirements:"The candidate must have more than 3 years experience in C++ programming" or "The candidate must have more than 3 years experience in iOS development". I would like to ask the recruiter:"Is working experience really so important?"In my opinion, the working experience is not a good measurement to decide whether a candidate is fit or not, and use this rule just like using the lines of code to judge the program is good or bad. Frankly, the grammars of every programming languages are similar, and the i...

TIOBE released the programming index for September 2012. There is no big change for this month compared to last month, the top 3 are still C, Java and Objective-C. In top 20, only Transact-SQL exchanged the position with VB.NET. Java shows trend of drop, will it be worse because of the ignorance of Java's vulnerabilities by Oracle.This index shows that the programing lnaguage market is quite normal, no big events. Except Objective-C, in recent years there are no other new languages which have big rank leap. If we expect that Scala, Dart or Clojure have big breakthrough, then how long should we...

One of the most important lessons I learned during the first year of my career is to be so nice to...

Hello world is the beginning of everything. When you first learn a new programming language, the first program you write is to print the "Hello world" string on the console with that language. For example:So who invented "Hello world"? It's Brian Kernighan, a canadian computer scientist and author of The C Programming Language and The Unix Programming Environment. In his books, he used to write "Hello world" which changed the whole world.Also programmers like to use foo and bar as variable names, weird names.Actually, beyond programming, other fields also have "Hello world" phenomenon.For exam...

Every process is initialized with three open file descriptors, stdin, stdout, and stderr. stdin is an abstraction for accepting input (from the keyboard or from pipes) and stdout is an abstraction for giving output (to a file, to a pipe, to a console).That's a very simplified explanation but true nonetheless. Those three file descriptors are collectively called 'The Standard Streams'.Where does stderr come from?It's fairly straightforward to understand why stdin and stdout exist, however stderr seems like the odd one out. Why do we need another stream for errors?This is a quote from Doug McIll...
