Watch as four running instances of ShadowClaw work together while responding to a scheduled task.

After working on Sprite Garden for a bit, I was curious if experimentation with WebGL using the same overall setup would be possible, and it was surprisingly enough that I’ve forked it, and called it Block Garden.

I’ve wanted for some time to build a canvas based JavaScript game after checking out things like the breakout game tutorial on MDN or reading and working through early Raspberry Pi project books, but I never felt like I built something I enjoyed.

The web platform continues to grow, and features continue to land as baseline.

I’ve added a hobby project to my GitHub profile that has been given the title “Apps” as it is a progressive web app that aims to adhere to the App Shell model.

I’ve talked about an experiment with Blazor in the past, but wanted to see how it would go building something small in C# for the browser without going through that process.

When using the terminal on my Mac, I often use the open command to get a view of the current directory in Finder and generally use it to… open up things.

HTML, JavaScript, and CSS are key parts of the Open Web Platform as they assist in creating customized, yet reusable solutions that anyone might need to build high quality, robust web applications—without requiring unnecessary complexity.

It seemed like a neat idea to encapsulate syntax highlighting responsibilities for the various code snippets that I share at times, so I went ahead and wrote a custom element to help me take care of the job.

Fast Traxx remote control wired up to the Raspberry Pi Connecting to the Raspberry Pi over SSH to drive the Fast Traxx I thought it was a good time to revisit trying to control an RC car’s handheld remote, so I returned to the community assistance I first…

After experimenting with the AIY Vision kit and the Coral USB Accelerator I decided to try “edge computing” from another angle by wrapping up TensorFlow.js with LitElement to make a few Web Components for testing.

While there are many ways to generate strong passwords, I’ve been a fan of using pwgen for systems that I stand up.

“WebAssembly becomes the fourth language for the Web which allows code to run in the browser“ I’ve been enjoying learning a little bit more about WebAssembly.

Rendering x-weather along with some of Polymer’s App Layout custom elements makes it look a lot better and paves the way for additional features.

The Raspberry Pi continues to deliver on cool projects to spend time with the family on.

While building using the custom elements v1 standard is achievable in a normal workflow, high quality libraries providing a wrapper on top of the standard seem like a more productive choice for my usage—especially any that offer a unified way to support I…

When I first started learning HTML, I remember the delight I had after applying only a little markup, and seeing the results after reloading.

Adding the Audits panel and powering it by Lighthouse was a good move by the Chrome team.

The time I’ve put into developing postpress seems like it has been well spent.

Web application development using React, Redux and server-side rendering has been exciting.

When interacting with a Windows system regularly, I like to install Cygwin.

The GoPiGo has been exciting to work with as a platform for building robotic cars.

Microsoft released PowerShell for OS X and Linux.

I’ve went ahead and updated the WordPress branch within my Vagrant Environments git repository hoping to kickstart all kinds of new experimentation on my own end.

I’ve been wanting to return to the motion detection setups I’ve created in the past [1, 2] on the Raspberry Pi, and update them a bit using some more recent development approaches.

Over the last year or so I’ve spent some time testing out Amazon Web Services.

I have been enjoying setting up and utilizing my development environments these days.

As I was checking out the latest accessories for the Raspberry Pi, I stumbled across this nice little shield at Adafruit: PiTFT Mini Kit – 320×240 2.8″ TFT+Touchscreen.

Recently I was able to spend some time with Bolt, “a tool for Content Management, which strives to be as simple and straightforward as possible.”

After finding Tasker for Android and realizing all of the potential it has, I had to try it out.

When the Gertboard originally came out, it was a do it yourself kit that required soldering, and it had enough pieces that made me want to wait until one was offered pre-assembled (you can still get one like the original from Tandy called the Multiface Ki…

For awhile I’ve wanted to connect an RC car to the Raspberry Pi by wiring up to a Tyco Fast Traxx remote control.

After checking out a page called Perl one-liners and reading how you could execute Perl inline on the CLI, I decided to try and replicate some grep functionality using PHP one-liners for fun.

In December of 2012 HTML5 became feature complete according to the W3C, “meaning businesses and developers have a stable target for implementation and planning.”

These steps were gleaned from the work completed by Reinhard Seiler.

I found a package manager for Debian that I’ve never heard of: Wajig.

As I was pulling apart a Power Macintosh 9600/300 today I thought it would be interesting to post about this ribbon cable I found inside.

The programmability of the Raspberry Pi comes in handy when you want to change the behavior of a circuit without moving a single wire.

With the faster release cycle and updating of Firefox, it’s been interesting to see features show up in the application like they do in web sites.

Since purchasing the Pi Cobbler Breakout Kit I wanted to digitally plan out the project before connecting a single wire.

Since getting a Raspberry Pi I’ve wanted to use the GPIO pins, but have tried to heed the various warnings regarding static and other issues one might face like using 3.3v vs 5v devices or how much power peripherals draw.

As I have been traveling through Getting Started with Arduino I’ve been trying to take on the “tinkering” mentality described in chapter two titled, “The Arduino Way“.

I got the Raspberry Pi in yesterday and wanted to show what came with it as well as my first steps.

After upgrading to Ubuntu 12.04 from 10.04, I realized Gimp was at an older version (2.6) than 2.8.

I recently completed a project for a customer that afforded me the opportunity to dive into Drupal on better terms.

I like that LibreOffice seems to be experiencing rapid innovation and bloat removal since The Document Foundation was formed, and the software was forked from OpenOffice.

Ubuntu 12.04 LTS Alpha 1 has been released.

I ran into an interesting issue today after a co-worker reported that he had been receiving emails from someone who claimed there were attachments, however they were not being displayed within the email.

This was fun.

I finally started working on Herrick Design.
