So you don't want to use Docker for Mac anymore, huh? First, let's install docker and virtualbox. brew install docker docker-machine brew install --cask virtualbox Now let's create a "docker machine" using docker-machine. This wraps around virtualbox to spin up a vm (and probably does other stuff). docker-machine create --driver virtualbox \ --virtualbox-cpu-count "4" \ --virtualbox-memory "8192" \ default Now we'll set up a credential store for docker. curl -O https://github.

A few years ago I started slowly transforming my house into a "Smart House". It started with some friends of ours showing us their smart bulbs and how they could tell Alexa to turn them on and off. I'll admit, I was skeptical of how smart bulbs could be life changing, and it took a few years until I would get there. But this isn't that story, this is about how I converted my plain ol' dumb fan into a Wi-Fi enabled smart fan for my OpenHab system. Read more → about Making a Wi-Fi Smart Fan (Part 1)

I bought a bag of integrated circuits (IC) from eBay — it is about 1/2 a pounds and contains all kids of TTL, CMOS, Semiconductors, etc. And the “etc” is very interesting. eBay seller — https://www.ebay.com/sch/oblagon/m.html I’m going to go through as many of them as I can and put them on a breadboard, reviewRead more Read more → about Wire Up Random Integrated Circuits

After about a year, I swap out my prototype furnace sensor with a permanent solution, complete with 3d printed case and two temperature probes. I will post a follow-up video once I get some graph data to show the vibration and temperature over a period of time. In a future video, I will cover inRead more Read more → about Is your furnace running?

When I was a senior in college (longer ago than I should admit to) I did a demonstration about sniffing user’s facebook traffic when they were using wifi at my college. At the time Facebook didn’t redirect HTTP -> HTTPS by default and most users were connecting over plaintext. Since then Facebook has switched to secure browsing by default, and most companies are encrypting traffic in transit whether it’s internal or external.

I’m not looking to add to the noise around using zoom to work remotely and connect with people during social distancing, but after spending some time on Google I couldn’t find a guide on how to do this. These are pretty much my own notes while I’m prepping to try and host a user group through zoom. Here’s my “minimal video call host check list” Let people know what they’re getting into (state that you’d like people to turn on video in the agenda, tell them what will happen during the meeting, ask for their patience while everyone gets used to the video chat)1.

I’ve been doing IaC in AWS for years now, primarily through Cloudformation and scripting languages like powershell and python. IaC is great, but these tools have some short comings like yaml being very verbose, and the powershell AWS SDKs not handling idem potency for you. Because of those short comings, I was very excited when AWS released AWS CDK a little over a year ago now. It cuts down on a lot of copying and pasting yaml files like you do in cloudformation, and gives you easier access to higher level language constructs like loops and if statements.

In the past year I left my position as a Web Developer to work as a Software Developer. Not only did I leave web development behind, the core languages I use every day changed. I switched from a primarily PHP/Javascript developer to a Python/C++ developer. Changing a tech stacks created a need for me to learn a lot about a new language very quickly, I’ve decided to write down some of what I learned.

Eleven kids, ten meet-ups, one shorted board, a dozen blown LEDs, zero burnt finger, one story on KDLT, and two months of fun & creativity. That sums up our fourth Hack Sioux Falls project hosted by Code Bootcamp School. When I first launched this project last year, I had no idea what to expect orRead more Read more → about Hack Sioux Falls Final Projects (Fall 2019)
