  Why Good Programmers Are Lazy and Dumb

I realized that, paradoxically enough, good programmers need to be both lazy and dumb. Lazy, because only lazy programmers will want to write the kind of tools that might replace them in the end. Lazy, because only a lazy programmer will avoid writing monotonous, repetitive code – thus avoiding redundancy, the enemy of software maintenance and flexible refactoring. Mostly, the tools and processes that come out of this endeavor fired by laziness will speed up the production. This ma...

  Find the kth smallest number in an array

This is an classical question, the general solution to this question is first using sorting algorithm to sort the array, then get the kth number in the array, the complexity is O(nlogn), we can also use selective sort or head sort to, the complexity of selective sort is O(kn) and heap sort is O(nlogk). The better solution is to use quick sort to find the kth smallest number, the complexity is O(n), the worst case cost is O(n^2). But today we introduce one more solution which has the worst case c...

  Emacs adventures

I have been using Emacs for over a year now. I actually didn’t learn a lot when I started using it (just the basics to get going and then some relatively common keyboard shortcuts), but lately I have been reading and learning much more about it. I’m so grateful by everything I’ve learned from different people on the net that I wanted to share a couple of things I’ve learned, and a simple major mode for editing AsciiDoc documents. As a long-time VIM user, I f...

  What Level Programmer Are You?

Everybody's talking about how programming is the skill that we all are going to need. [Except those folks who might feel that most programming could be turned into wizard-like tools. Insert long discussion about Strong AI.] But what's a programmer? Is the guy who set up his own Apache Web Server a programmer? How about the guy who created a complex Excel spreadsheet? The guy who made his own RPG level? Minecraft players? When we say "Everybody is going to have to know programming" what, e...

  How small should a function be?

"The well-designed functions are often relatively small, large function design is often a mess or there is a lot of room for optimization."Maybe you think there is no need to discuss the size of functions, because the nature of the function design is cohesive, its size is only its manifestations. But it is necessary to discuss about the size of function because the statement above .First let's understand the concept of minimum code processing unit : a basic operation (assignment, comparison, etc...
