Manipulate Images with ImageMagick

In my last article, I had some fun looking at the children's game of rock, paper, scissors, writing a simple simulator and finding out that some strategies are better than others. Yes, I used "strategy" and "rock, paper, scissors" in the same sentence! more>>

Gabriel Ford, Sadie Ford and Melissa Ford's Hello, Scratch!

In the new book Hello, Scratch! (published by Manning Publications), parents and kids work together to learn programming skills, but not in just any old way. They create new versions of old retro-style arcade games with the Scratch open-source visual programming language from the MIT Media Lab. more>>

Rogue Wave Software's Zend Studio

The quick pitch for Rogue Wave Software's Zend Studio, recently updated to version 13.6, is "the PHP IDE for smarter development". Zend Studio 13.6, says Rogue Wave, offers 3X faster performance in indexing, validation and searching of PHP code, and it allows users to code faster, debug more easily and leverage the massive performance gains in PHP 7. more>>

Scissors, Paper or Rock?

In this article, I'm going to tackle a children's game that's extraordinarily complicated, with many variations, and the programming task is going to be quite tricky. Just kidding! Rock Paper Scissors (or RPS, as it's known) is pretty darn easy to simulate because there aren't really many variants or possible outcomes. more>>

FreeDOS Is 23 Years Old, and Counting

The FreeDOS Project has just reached its 23rd birthday! This is a major milestone for any free software or open-source software project. more>>

Is the Moon Waxing or Waning?

In my last article, I talked about the complications of calculating the phase of the moon and decided simply to scrape the same website that Google uses. more>>

AdaCore recently announced the concurrent annual release of four flagship products in its portfolio of software development and verification tools for mission-critical, safety-critical and security-critical systems. These include version 17.1 of GNAT Pro, CodePeer, QGen and SPARK Pro. more>>

Pythonic Science in the Browser

In the past, if you wanted a friendly environment for doing Python programming, you would use Ipython. The Ipython project actually consists of three parts: the standard console interface, a Qt-based GUI interface and a web server interface that you can connect to with a web browser. more>>

The Current Phase of the Moon

Ladies and gentlemen, we've left Mars. Well, at least I'm done with the Martian lander from my past few articles. I hope you had chance to experiment with it and find out that it's not too easy to land a craft on any planet! more>>

The Family Dashboard

I've written a little about PHP before, because I think it's a great utility language for writing quick things you need to do. Plus, it allows you to use a web browser as your interface, and everyone has a web browser. That makes it very convenient for my family, because I can make simple web interfaces for the various things I normally have to do from the command line. more>>

Wrapping Up the Mars Lander

In my last few articles ("Let's Go to Mars with Martian Lander" and "Mars Lander, Take II: Crashing onto the Surface"), I've been building a variant on the classic video game Lunar Lander, with a few simplificatio more>>

Mars Lander, Take II: Crashing onto the Surface

In my last article, I spent almost the entire piece exploring gravitational physics, of all unlikely topics. more>>

Natalie Rusk's Scratch Coding Cards (No Starch Press)

The phrase "Learn to Program One Card at a Time" plays the role of subtitle and friendly invitation from Scratch Coding Cards, a colorful collection of activities that introduce children to creative coding. more>>

Bash Shell Script: Building a Better March Madness Bracket

Last year, I wrote an article for Linux Journal titled "Building Your March Madness Bracket" My article was timely, arriving just in time for the "March Madness" college basketball series. more>>
