Type 2 fun is a perfect example of the fading effect cognitive bias.
Fading effect bias interestingly causes the emotion associated with negative event memories to generally fade faster than the emotion associated with positive event memories.
You can show/hide terminal windows with a hotkey natively using iTerm2.
Under Preferences > Keys > Hotkey I've set the system-wide hotkey to option+space which means if I need a terminal, I can press those keys and have iTerm pop up over my active window.
Pressing them again hides the window and brings focus back to the previously active window which has been great for productivity.
Boxen (https://github.com/boxen/puppet-boxen) used Puppet to achieve this. It worked, but it was quite opinionated and of course you needed to know Puppet so the learning curve was steep. It's since been superseded by Homebrew which I find is a far better experience.
This is where the maxim of open source being 'free as in puppies not free as in beer/lunch' comes from.
I started my career in open source and still strongly believe in FOSS tenets, but enterprises are looking more to de-risk their projects and platforms.
Risk is reduced when you have a vendor you can hold accountable for issues in the product, hence making proprietary solutions (and sometimes open source but wrapped in enterprise support solutions) the only viable choice for a business.
My experiences were very similar to the author’s when I first started using it. Even though my test coverage was near 100%, the mutations introduced revealed that in large part my tests were fallible due to assumptions I’d made when writing them.
I’ve incorporated mutation testing as the final step in my CI workflow as a test for my tests. It’s a fair bit of work the first time it’s run (especially with larger libraries), but in my opinion vital as a pairing with tests.
I found something like this when managed to accidentally break the Drupal.org git parser by adding emojis to a commit message. It wasn't on purpose, I was just on a 2015 emoji kick.
That said, it did uncover a bug that obviously hadn't been tested for which gave the infra team more impetus to solve utf8mb4 support for the database.
I’ve found that using geerlingguy’s Ansible roles for MySQL, Nginx, and PHP, most random PHP applications can be deployed with default configuration. I’ve had them in production with Matomo for the past year or so and had no problems so far.
A lot of the challenges faced with a ‘from scratch’ install will revolve around which PHP version and extensions to install and how to get Nginx to talk to FPM. Neither of which are trivial for someone wanting to test/evaluate without much prior knowledge.
