Today marks the release of PixelMaestro version 0.8! This release introduces several big changes including new features and better performance. To learn more, keep reading or visit the PixelMaestro GitHub page.
On today’s episode of “Adventures in C++”: sending commands between two Arduinos running the same software. Not just data, but also instructions on how to process and execute that data. Even more, these commands have to be small enough for each Arduino to package, send, receive, unpack, and execute in less than 1/10th of a second.
UPDATE: Shortly after posting this, I switched to a different method using a custom data serialization protocol, which you can learn more about here.
One of the coolest things about C++ is how flexible the language is. If you’re faced with a problem that has no apparent solution, chances are you’re just not approaching it from the right angle.
In my never-ending (and often misguided) quest to bridge the world of writing and programming, I decided to take a crucial tool from the software world and use it to manage my documents. The result: a powerful (if convoluted) system for drafting and revising documents.
This is the first public release of PixelMaestro, a C++ library for generating 2D animations!
When I first started this blog, I was just dipping my toes back into the world of C++. Before that, my experience with it was mostly academic, and after struggling through a course with a particularly poor professor I swore off it in favor of VB.NET. No, I never did forgive myself for that decision, but it ultimately helped me learn to appreciate the importance and relevance of C++. And after tinkering with systems that use C++ exclusively, I’ve come to appreciate it even more.
There’s a movement underway to transform the way we interact with personal computers. As computers become more automated and more intelligent, consumers are losing access to the software that makes them tick. The emphasis is moving away from computers as a platform and closer to computers as an appliance. What does this mean for end-users, and what does it mean for the future of our digitally dependent society?

Far below the Web we all know and love, behind the friendly faces of our favorite websites there lies a lurking giant. Many of us know the Web by it’s biggest names – Facebook, Twitter, Google, etc. But what many of us don’t know is that there’s another component to the Web, one that willingly places itself away from the public consciousness. It’s given rise to a platform where people around the world can speak freely without fear of retribution, but it’s also given rise to a platform where people can engage in incredible atrocities outside of the public eye. This mysterious hidden network is known as the Dark Web.
Backups are something most people never think about until it’s too late. Computers can be finicky, and if you value your digital data then you’ll want to have a backup solution in place. This post explores two aspects of backups: the various types of backups, and everyday tools for performing those backups.
Disclaimer: Parts of this guide include instructions that, if misused, could result in data loss. Never run a command without being 100% sure of the outcome!
Installing programs is something most people take for granted. How could it be easier – you simply download an installation file, run it, answer a few prompts, and before you know it you have a fresh new application ready to go. This is fine for a single-user system like a laptop or desktop, but what happens when you want to share that program with someone else, or migrate it – along with its configuration and settings – to a different computer? What if you wanted to do a clean reinstall without having to hunt for scattered or leftover files? Better yet, what if you could run the application in a completely self-contained environment without it affecting your main system? Docker provides a unique way of accomplishing this, and the technology behind it is quickly gaining traction. Continue reading “Contain Your Excitement: Building Portable Apps with Docker”
