Ubuntu Command for Mic Mute with Pulsemixer

One of the major problems I run into with video conferencing tools is how many of them are not at all accessible. I'm a keyboard-only user so if I need to hover a pointer in a particular area of the screen and then click an icon to mute ... then I can't do that. And if you mute me when I join because there are a lot of people here, then I can't participate at all. To work around this, I need a one-liner to mute (and unmute) my mic ... so here it is.

Combine Multiple Field Tags in Go

I work a lot with JSON APIs in my Go projects, so almost every struct has some field tags on it to translate AccountID into account_id and that sort of thing. Then one day I needed to load data from config using mapstructure and it took a few attempts with the search engine to find the syntax I needed, so it's here for next time I need it (or in case you need it too).

Using Environments in Postman

I'm using Postman more lately and showing off the Environments feature really often. I really like this feature for giving easy ways to handle values I use frequently, but it seems to be a bit of a hidden gem, so I thought I'd write about when I find it useful, in case you do too! Continue reading

Accessing Nested Config with Viper

I'm writing a Go application that glues together a bunch of other things, so it has a whole bunch of basically unrelated config, dumped in a yaml file. I was struggling a little with this non-standard use of Viper but actually, it does everything I needed. And, presumaby, more besides. I thought I would put some examples here to show how to handle this. Continue reading

Remove Accidental Content from Git Commit

When I teach git I try to show loads of good practice about how to inspect what's staged before commit, etc etc. Good practice is good of course, but knowing how to undo a mess you created is better - and mistakes will happen. For example, accidentally including a node_modules directory in your otherwise excellent and useful commit. This post will walk you through how to fix the problem without losing any of your work.

Counting Duplicate Commit Messages

When chatting about source control good practice the other day, I got a question about repeated git commit messages. In general, I would always advise that the same commit messages appearing multiple times in a project's history is a definite red flag - and if I'm responsible for that repository I will probably make fun of you for doing it.

Managing Environment Variables in PHP

Now I work with more programming languages, I start to miss features from other languages when I come "home" to PHP. One that I hadn't seen in PHP before I saw it in other languages such as NodeJS (I think Ruby had the original implementation) was: a way to easily control setting your environment variables, particularly in development. In NodeJS the dotenv library is great for this; handily in PHP vlucas has already created phpdotenv so we are all set to apply these tricks to PHP applications! Continue reading
