Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Problem

When I click on links from Slack or Outlook on MacOS they open in seemingly random browser windows/profiles. This is annoying.

Solution

Open links in a particular google chrome profile window. Be less annoyed.

Install Finicky: brew install finicky. After install it should be running and you should see the icon in the upper toolbar.
From the Finicky Toolbar Item, click > Config > Create New
Edit the new file ~/.finicky and make it look something like this, filling in your profile name:

Solution Steps

1. Check for GPG Lock Messages

Open your terminal and try to perform a GPG operation (like signing a test message). If you see repeated messages like gpg: waiting for lock (held by [process_id]) ..., it indicates a lock issue.
