This is a continuation from Part 1. You should probably read the previous post before reading this one. All of the disclaimers and warnings at the beginning of Part 1 apply here.

In the previous step we laid out the data types that the
BasicBot struct would need to function properly. Now, we’ll lay out the behavior for the bot. To do that we’ll start by filling out the

For those that are unfamiliar, Twitch.tv is a live-streaming platform for all things creative and related to games. Not necessarily just video games. Content creators play board games, roll-play games (e.g. Dungeons & Dragons), and everything in between. On this platform, streamers are able to interact with a live chat room just for their channel (with a delay).
To facilitate the streamer and chat interaction, Twitch uses a variant of IRC, and provides documentation for their implementation on their Twitch Developers page. This allows developers to create chat bots that can moderate chat rooms, interact with chatters, and automate certain tasks for streamers. There are several well known ones, with many features, but the chat bot built in this walkthrough won’t be as complex.

I ran into a situation with a project where I needed to build two separate programs to work together. The first being a server, and the second being an on-going client-facing process. The server is designed to kick off any number of instances of the on-going process. Before having written any code to have the server run the on-going processes as children, I had intended the child processes to be independent of the server. That is, if the server went down, the child processes would still function. They would store requests in a queue and periodically attempt to reconnect to the server. Once the connection was re-established, everything would go back to normal. It turned out that Unix processes don’t quite work like I had expected.
In reality, when a process spawns another process, it is called a “child”; the original is called the “parent”. As long as the parent process has not exited, the child will continue to run. If for some reason the parent goes down, so does the child. That is, unless the child is considered “detached”. A child process is detached when it no longer has a parent (I believe that technically, parent-less children are owned by an
init process). Thus, you can have a parent process spawn a detached child and immediately exit, which will leave the child process all alone.

Just the other day, I moved my portfolio to a separate server and started serving it over HTTPS. I was super stoked when it was all done! I wanted to talk a bit about what steps I took, since I found some annoying gotchas along the way. This isn’t a step-by-step tutorial, rather I’m sharing the configurations that finally got it working for me.

html/template package. Since the
html/template package provides support for calling functions assigned to data passed to the
template.Template.Execute() function, templates can fire off the localization process themselves. Once you have a template setup to utilize the localize package, it’s a fire and forget situation. The best kind, in my opinion.
One of my projects involves a lot of console output, and to make it readable, I added some color. Cyan for important messages, red for errors, and yellow for normal (everything is fine) logs.
The short of it is: I wanted to do the same somewhere else, so I published it.
If you’re a Go developer and want some quick and easy functions to color things, check it out.
Here’s the GitHub repo if you want to see the README. Or, you can just
go get github.com/foresthoffman/rgblog and use it right away.

I recently moved my web development workspace from MAMP to LAMP with Docker. The transition was difficult, due to issues with Ruby and RVM on my host machine. Now that it is working, all is well!
When I started tinkering with Docker, my goal was just to see if I could replicate my WordPress development environment. After I did that, I improved it a bit. Now, i’ve suitably compartmentalized each project. Each WordPress project has its own WordPress installation, MySQL server, error logs, plugin and theme directories.
The only thing missing was being able to run unit tests!

The Parsedown Importer plugin allows administrators to import Markdown files into posts and pages. In addition to a helpful interface, the importer provides a series of settings to control how the posts or pages are created.

Ambient Weaver is an ambient sound player for macOS 10.12.2+ and Windows 10. The core mechanics of the player include the ability to create playlists which contain customizable sound tracks. Each track has controls for volume, a starting point, and whether or not the track should repeat. Normal audio players, designed for non-ambient songs, run one track at a time. When those players are used for ambient sounds, there are always momentary breaks in the sound that can break the listener’s concentration. That is the nature of having one playback loop. Ambient Weaver gives each track it’s own loop. This allows for tracks to be overlain in a way that masks the momentary breaks, creating a seamless listening experience.
