  C++ Versus Objective-C

What will programming in Objective-C mean to the C++ programmer Different Object Oriented Languages Almost all of us have heard the term object oriented programming, and most of us have used C++. How will Apple's purchase of NeXT, and NeXT's framework using Objective-C affect us as we develop software? If we know C++ already, how hard will it be to get up to speed on Objective-C? Many people will agree that once they understand the concepts of object oriented programming it doesn't matter...

  Functional Programming in C++

Probably everyone reading this has heard “functional programming” put forth as something that is supposed to bring benefits to software development, or even heard it touted as a silver bullet.  However, a trip to Wikipedia for some more information can be initially off-putting, with early references to lambda calculus and formal systems.  It isn’t immediately clear what that has to do with writing better software. My pragmatic summary:  A large fraction of th...

  Are You a Good Programmer?

If someone asks you to recommend a good programmer, who comes to mind? Do you consider yourself a good programmer? What criteria do you use to judge? In thinking about this, I realized that there are different ways that a programmer can be good. So I present to you The Four Kinds of Good Programmers. And in celebration of Whyday, I include quirky Why-styled illustrations* for your viewing pleasure! The Philosopher The PhilosopherThe philosopher loves to write well-defined, well-structured...

  JavaScript: Private variables

The first thing you often hear when talking about JavaScript is often “JavaScript doesn’t have visibility modifiers, hence it doesn’t support private variables”. This is only valid for 50%, because JavaScript indeed doesn’t have visibility modifiers (public, private, friend) but it has closures and function scopes. With these tools we can make variables private. Let’s take the following function: var names = ["Kenneth", "John", "Marc", "Robert"]; var lookup =...

  The Greatest Regex Trick Ever (Simplified)

There is a post which is really hot recently which showcased a best ever regular expression trick. In this post, it provides a trick which can be adapted to situations where one wants to match some patterns desired and exclude the patterns undesired. In simple, the trick is : Pattern not desired | (Pattern desired) Then taking the group 1 match of the capturing group of matched. This group will contain the strings matching the desired patterns. Have to say this trick is really neat and brilliant...

  Ruby is beautiful (but I’m moving to Python)

The Ruby language is beautiful. And I think it deserves to break free from the Web. I think the future of Ruby is firmly stuck in Web development, though, so I’m going to invest in a new language for data analysis, at least for now. This is a look at the fantastic language I came to from Java and a look at a possible candidate. (Update: I’ve since written a followup.)Java to RubySix years ago, I added Ruby to my technical arsenal. I learned C++ and Java in high school, and I p...

  Fear of Ignorance

This past week, I was interviewing a candidate for a VP role along with two of our engineering leads. Everyone in the room excluding myself was classically “technical” – they could write code, had experience solving hard software problems and a background in computer science. I wrote my last line of PHP in 2004, and it had to be rewritten by a real programmer within 6 months.During the interview, we had the following exchange (due to an imperfect memory, I’ll ...

  Is Java Set ordered or not?

“Is Java Set ordered or not? ” is the most popular question asked when you interview for a Java Developer position. Many fail to answer it, and I have to admit I was one of the many. I have known the answer is “Yes and No” for a long time. No. HashSet is not ordered. Yes.TreeSet is ordered. If the interviewer continues with some follow up questions, I’m not confident that I know the answer then. Why is TreeSet ordered? Are there any other ordered S...

  Python SSH Connection Tools

Program Design Purpose: We aim to create a simple Python SSH tool library that facilitates SSH communication, SCP file transfer, and SSH port forwarding through multiple jump hosts in an SSH tunnel chain. The library is designed to provide a simple API for establishing nested SSH tunnel connections through multiple jump hosts with customizable TCP ports. This allows users or their programs to automate SSH tasks such as: Batch processing SSH connection tasks, such as connecting to multiple ser...

  What I learned from Google - You Get Fifteen Years

four years ago I was in Mountain View, California, interviewing for a position with Google. It was an odd sort of interview.  Lots of puzzles, math-like challenges, and code.  Lots, and lots, and lots of code. What struck me at Google wasn’t the challenges.  Nor was it the office environment, the cafeteria, or the mini-swimming pool, all of which were impressive. No, what struck me were the people. All of the people I met — and I mean all of them — had this ...
