Learn how to program in Python by building a simple dice game

Python is an all-purpose programming language that can be used to create desktop applications, 3D graphics, video games, and even websites. It's a great first programming language because it can be easy to learn and it's simpler than complex languages like C, C++, or Java. Even so, Python is powerful and robust enough to create advanced applications, and it's used in just about every industry that uses computers. This makes Python a good language for young and old, with or without any programming experience. read more

A 7-step plan for engaging your community's naysayers

When you practice open communication and invite feedback, you get a lot valuable input that can improve your ideas, projects, and decisions. Yet one of the most common questions I hear is this: "That's all well and good, and I agree, it's best to open yourself up to that kind of feedback. But what about that one guy. . .?" You know the one they're talking about. It's Mr. Grumpy, who inevitably shows up and says things like, "Oh, that won't work here" or "We already tried something like that," yet never seems to offer any helpful or productive alternatives. read more

I grew up in the 1970s and 1980s. My parents wanted to expose my brother and me to computers from an early age, so they bought an Apple II clone called the Franklin Ace 1000. I'm sure the first thing we used it for was playing games. But it didn't take long before we asked, "How does it work?" Our parents bought us a book about how to program in Applesoft BASIC, and we taught ourselves. read more

4 website maintenance mistakes to avoid

  • Opensource.com (Posted by bob on Oct 16, 2017 2:46 PM EDT)
  • Story Type: News Story
Maintenance is a good idea for every website, but it's a requirement for websites using open source code. The upside of open source is that everyone can participate. The downside is that means keeping up with everyone's changes. Code gets patched, which causes other code to stop working and need patches in turn. Exploits are found and then blocked. Fancy new features are developed, and your users want them. All of this means you need to keep up! The most important weapon to combat these forces is maintenance. read more
