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 ...

Coding is sort of like a superpower; with it you can create things that millions of people see. You can change the way people behave, the way they think, and the way they interact with others. This is beyond awesome, but I’ve also met a lot of people that think that this ability is inaccessible to them. I’ve met a lot of “non-technical” people who seem to think that this superpower is only bestowed on those fortunate enough to have it come easily to them at a very early age.I took two Computer Science courses in high school, and I’m fairly confident that had it...

I’ve been asked this question a lot lately, especially after I built YouTube Instant. So, here’s the answer, once and for all, for those who are interested.In short:I learned how to program by building lots of websites.The full story:I learned how to program by working on lots of different website projects starting from a pretty young age. What follows is a full account of all the major websites I’ve built, back to the very first site I made when I was 11 years old. What I hope the reader takes away from this full retelling is the importance of doing lots of side...

As we noted earlier this week, one of the founding fathers of UNIX and the creator of C, Dennis Ritchie, passed away last weekend. While I feel that many in computer science and related fields knew of Ritchie’s importance to the growth and development of, well, everything to do with computing, I think it’s valuable to look back at his accomplishments and place him high in the CS pantheon already populated by Lovelace, Turing, and (although this crowing will be controversial, at least until history has its say) the recently-departed Steve Jobs.UNIX was one of the first multi-user ...

A programmer’s greatest enemy is getting stuck. A crucial skill in programming—and one that many of my beginning game programming students lack—is the ability to recognize when they’re stuck, to get out of being stuck, and to avoid getting stuck in the first place.Indeed, it’s a skill I’m still learning myself, although the contexts in which I still get stuck are shrinking with time, study, and experience.This morning, as I downloaded crash reports from Apple, I realized I was dreading my job today. I started looking for other things to do—...

C Program to shutdown your computer :- This program turn off i.e shutdown your computer system. Firstly it will asks you to shutdown your computer if you press 'y' the your computer will shutdown in 30 seconds, system function of "stdlib.h" is used to run an executable file shutdown.exe which is present in C:\WINDOWS\system32 in windows-xp.

If you wish to restart your c...

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, ...

Similarities:Java and C have same syntax operators.Difference—thinkingTwo paradigms:Java: Object oriented languageC: Structured languageDifferences: --SyntaxNo preprocessorJava does not include a preprocessor and does not define any analogs of the #define, #include, and #ifdef directives. Constant definitions are replaced with static final fields in Java. (See the java.lang.Math.PI field for an example.) Macro definitions are not available in Java, but advanced compiler technology and inlining has made them less useful. Java does not require an&nbs...
