  Why 0.1+0.2 != 0.3

In programming languages such as JavaScript, c/c++, Java and Matlab, you will find that you will get unexpected result when doing float point calculation. For example, when calculating 0.1 + 0.1, you will not get 0.3: > 0.1 + 0.2 == 0.3 false > 0.1 + 0.2 0.30000000000000004 Don't be surprised of this result, this is the end result of IEEE 754 standard, float point number cannot be accurately represented according to IEEE 754 because: No enough memory is allocated for representing the num...

  TIOBE: PHP is coming back

TIOBE released the programming language index for July 2013. The highlight of this month is that PHP is coming back. It ranks the fifth and has an increase of 1.54% compared to January. There are no changes in the ranking for the top 4 languages. The reason why PHP is back may be attributed to the new PHP Zend Framework that was released in September 2012, but this reason is not very convincing.

  Exit main thread and keep other threads running in C

In C programming, if using return in main function, the whole process will terminate. To only let main thread gone, and keep other threads live, you can use thrd_exit in main function. Check following code: #include #include #include int print_thread(void *s) { thrd_detach(thrd_current()); for (size_t i = 0; i < 5; i++) { sleep(1); printf("i=%zu\n", i); } thrd_exit(0); } int main(void) { ...

  In defence of Objective-C

An unashamed apologist’s perspective on the loveliest language i’ve worked with.I’ve worked with a lot of programming languages in my time. Not a huge number, mind you, but enough that i can say that i’m open minded and seasoned about it. And, as they say: ‘Don’t feed the trolls’ – well, i’m about to do exactly that: feed the trolls at work who love to rag on about how awful obj-c is! So here i go, foolishly treading where no sensible...

  How GitHub Works: Creativity is Important

We want to foster a creative environment. We love it when employees hack on side projects. It gets people excited. Excitement is contagious, and spreads easily from one project to another. Even if we’ll never make money on that side project, the excitement generated from it can bleed into things that will make us money. Alcohol It’s no secret that there’s more than a few people at GitHub who like to drink. I mean, we have four beers on-tap at the office in our kegerator. B...

  How I Program Stuff

I love programming. I can truly say that of all the things I enjoy, I enjoy programming the most. There's nothing quite like the feeling you get when you create something. Writing code is a lot like building your own little universe. When you build stuff, you're in complete control, and, no matter how hard you fight it, your code directly reflects yourself. If you write sloppy code, I can almost guarantee you'll be a sloppy person. If you haphazardly throw code around with any ca...

  Yes, Virginia, Scala is hard

Let me first say that I am a Scala lover and have been a Scala champion for almost 5 years.  I've written books and articles on Scala.  I've worked with dozens of companies that have launched Scala and Lift projects.  I've code reviewed many dozens of Scala projects.I used to think that Scala was easy.  It was, and continues to be, a cure for some of the numerous problems with Java.  From the "stuff that's hard or impossible in Java is simple in Scala," Scala is a very e...

  Top 5 Reasons Not to Use Hadoop for Analytics

As a former diehard fan of Hadoop, I LOVED the fact that you can work on up to Petabytes of data.  I loved the ability to scale to thousands of nodes to process a large computation job.  I loved the ability to store and load data in a very flexible format.  In many ways, I loved Hadoop, until I tried to deploy it for analytics.   That’s when I became disillusioned with Hadoop (it just "ain't all that"). At Quantivo, we’ve explored many ways to deploy H...
