  Pointers, arrays, and string literals

A recently posted question on Stack Overflow highlighted a common misconception about the role of pointers and arrays held by many programmers learning C.The confusion stems from a misunderstanding concerning the role of pointers and strings in C. A pointer is an address in memory. It often points to an index in an array, such as in the function strtoupper in the following code:void strtoupper(char *str) { if (str) { // null ptr check, courtesy of Michael while (...

  socket_create() from command prompt with WAMP

Problem:I’m working on a wamp system, and have started playing around with sockets. I enabled sockets via the wamp interface:wamp : PHP settings : PHP extensions : php_socketsand could run my php file via my browser.When trying to run the same file via the command prompt (start : run : cmd), I got the following error:Fatal error: Call to undefined function socket_create() in … on line …Solution:The command prompt uses a different php.ini file to the apache server.The Apac...

  Rails and Web Development - Take the First Step

Getting started with web development isn’t easy. Looking back to when I started, the first few weeks were the toughest to stick with it. For someone who is new to text editors and the terminal – the installation process can be really overwhelming. I recently went through the process of helping some of my friends get set up with Ruby on Rails and after doing it a few times, I realized it would be helpful to write a post that others looking to get started could refer to.The following...

  Most Pressed Keys and Programming Syntaxes

I switch between programming languages quite a bit; I often wondered what happens when having to deal with the different syntaxes, does the syntax allow you to be more expressive or faster at coding in one language or another. I dont really know about that; but what I do know what keys are pressed when writing with different programming languages. This might be something interesting for people who are deciding to select a programming language might look into, here is a post on the...

  Command Line Arguments

Our Hello program still isn’t very general. We can’t change the name we say hello to without editing and recompiling the source code. This may be fine for the programmers, but what if the secretaries want their computers to say Hello to them? (I know. This is a little far-fetched but bear with me. I’m making a point.)What we need is a way to change the name at runtime rather than at compile time. (Runtime is when we type java HelloRusty. Compile time is when w...

  Glass Button in Photoshop

These days glass buttons seem to be very popular. You can find glass buttons in Windows Vista and all around the Web. Other popular buttons are metallic and plastic buttons. All these buttons have one thing in common: They are all shiny. Some people call these kinds of buttons Web 2.0 buttons. Here I cover the creation of two different glass buttons in Adobe Photoshop CS3. Both glass buttons utilize the same principles. Once you have completed this tutorial you should be able to apply ...

  I've got an idea for an app

I’ve been an iPhone developer for over three years now. The first app I built was CookieCombo. We sold enough copies to go bowling twice, but still it was completely worth it. We tweeted about it, and got some awesome gigs out of that. Everybody was in need of iPhone developers, and there was a huge shortage. Good times.As more and more people got to know that I’m an iPhone developer, I got to hear the following phrase more often: “Hey, you know, I got a great idea for an app...

  How can I teach a bright person, with no programming experience, how to program?

I usually prescribe the same sequence for anyone who wants to learn programming. It's very theoretical, but it lays a good foundation. It should take three or four months of fulltime study, but programming isn't something you learn overnight.If you can't get through this sequence, you're not going to be able to program, so you might as well give up now.Code, by Charles Petzold.The C Programming Language, K&RThe Structure and Interpretation of Computer Programs, Abelson and Sussman.My rule is...
