While working on the next release of PixelMaestro, I came across a problem of storing long-term data on an Arduino. I have a system in place where configuration changes are sent to an Arduino over USB as byte arrays, and as the Arduino reads the array it applies the changes. The problem is those changes disappear as soon as you restart the device. How, then, does one store persistent data without having to add an SD card or extra memory? Enter EEPROM.
In an earlier post, I explored the idea of productivity gamification and how it can help increase your motivation. I’ve been testing this over the past few weeks by using an Android app called LifeRPG to track my habits, tasks, and important milestones I wanted to reach. In this post, I’ll go into detail about my LifeRPG setup and how it’s helped me stay focused in my everyday life.
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.
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.

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”
