  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...

  Cripple Pachebel's Canon on Matlab

What can Matlab do? What the following Matlab code does is playing the piano music of Cripple Pachebel's Canon. You can have a try if you have Matlab installed on your computer. % Cripple Pachebel's Canon on Matlab % Have fun fs = 44100; % sample rate dt = 1/fs; T16 = 0.125; t16 = [0:dt:T16]; [temp k] = size(t16); t4 = linspace(0,4*T16,4*k); t8 = linspace(0,2*T16,2*k); [temp i] = size(t4); [temp j] = size(t8); % Modification functions mod4 =...

  What? You tattooed code on your arm?

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 com...

  Ways to undo wrong Git operations

While using Git to version code, programmers would inevitably perform some invalid operations which are not expected. Sometimes it's difficult to deal with this kind of awkward situations. If the programmer chooses to undo the operation, the programmer needs to bear the risk of deleting something which is not supposed to be deleted if the undo is done improperly. If the programmer leaves it as is, the file needs to be updated again manually with a new commit. In this post, we will try to pr...

  Find max subarray of an array

In computer science, the maximum subarray problem is the task of finding the contiguous subarray within a one-dimensional array of numbers (containing at least one positive number) which has the largest sum. For example, for the sequence of values −2, 1, −3, 4, −1, 2, 1, −5, 4; the contiguous subarray with the largest sum is 4, −1, 2, 1, with sum 6. The problem was first posed by Ulf Grenander of Brown University in 1977,...

  I am a great programmer, but horrible algorithmist

I am a great programmer, but a horrible algorithmist. It is a thought that has been weighing on me heavily recently, and I'd like to gather other developers feelings on the subject as well. I started what can be called my professional development career back in 1999. I was still in middle school, but my father hired me at his software company. My official duty was to make updates to our websites, but I mostly ended up bugging the other developers to help me learn. From there I picked up ...

  I hate cut-and-paste

Me, I blame the IDE's.Coding used to be hard. Not because programming itself was overly hard, but mostly because editors absolutely sucked. How much the typical development environment in the 70's and 80's sucked is hard to convey (except for a very lucky few, and those would have likely been using DEC and WANG gear). I got in on the tail end of the punch card era. Punching your own program is lots of fun. Once. And if you drop a deck you get to play with the sorter, which is also lots of fun (o...

  Program Or Be Programmed

On Thursday night I gave a talk at NYU Poly and in the Q&A a young man asked me for advice for "those who aren't technical". I said he should try to get technical. The next morning I met with a bunch of Sloan Business School students doing a trek through NYC. A young woman asked me the same question. I gave her the same answer.I don't mean that everyone should become a software engineer. I do mean that everyone should understand software engineering (or whatever technical...

  Why I switched from Ruby back to C++

After two months of Sol Trader development in Ruby, I took a difficult decision last Wednesday morning: I’ve decided to rewrite the game code from scratch in C++. Let me explain my reasons. If you'd like to receive announcements about Sol Trader or be part of the beta program, sign up at soltrader.net. Why I did it Slow frames: When working with Ruby, I use the excellent Gosu library to do all my game specific coding. This initially worked great, but occasionally I’d just...

  20 Database Design Best Practices

Use well defined and consistent names for tables and columns (e.g. School, StudentCourse, CourseID ...).Use singular for table names (i.e. use StudentCourse instead of StudentCourses). Table represents a collection of entities, there is no need for plural names.Don’t use spaces for table names. Otherwise you will have to use ‘{‘, ‘[‘, ‘“’ etc. characters to define tables (i.e. for accesing table Student Course you'll write “Student Cour...
