Here I will focus on tools and techniques almost any dev can adopt.
Reduce The Friction Between Your Brain And Your Code
1.) Work on a machine that responds instantly to most of your commands. A slow machine kills productivity.
2.) We constantly work with text, lots of text! Finding text quickly, before short term memory loss, is a critical skill:
- Can I find all matches of
getState()in 3 seconds?
- Can I delete all lines having
<span[\s]*data.+>.+<\/span>without looking into every file?
For this, learn tools like
sed plus regular expressions and IDE
shortcuts. I hated regex until I understood it, now it’s like a super power.
3.) Modal editors (Vim, Emacs) have a steep learning curve, but their payback is huge over a 20+ year career. Once you learn the meta-language of Vim or Emacs, macros are just a few keystrokes away. Tasks like refactoring are easier and less error prone.
4.) The mouse doesn’t just slow us down, it interrupts our flow. Can you switch windows and launch programs without a mouse? Accessibility features of the OS are not only for disabled users. Learn shortcuts for tasks you constantly do, like switching between an IDE and browser.
5.) Adopt Infrastructure as Code (IaC): If our shared testing and production resources are disposable, then we are forced to automate the processes which replace them. Why not extend this principal to your local desktop? Use Docker locally as a kind of dogfooding against what DevOps does for production.
Source control your dotfiles and push more stuff into containers. Cloud native technologies are not just for the cloud. They also bring predictability and resilience to a desktop environment - saving you time and possibly eliminating “works on my machine” errors.
Magic is when something works and I don’t know why. It’s fine for most of what my computer is doing – I don’t know how a Google search actually works, for example – but I avoid magic for code and configurations I own.
One way to stamp out magic is to read official documentation. Often it’s surprisingly good!
Another way is to use the terminal for programs designed to be used on the terminal. GUIs are great for visual tasks like 3-way merges, but don’t use a GUI for all Git tasks just because a few are confusing in the terminal. The terminal gives direct access to inputs and outputs of the program itself. This is The Unix Way.
Document Why (And Sometimes How)
I have, many times, changed my mind when writing code-level documentation. To give an example:
- Do we really want this data to remain across page loads?
- What if the filter settings are changed?
Writing useful comments forces me to think through the implementation enough to explain it to others and maybe convince them it’s a good idea. I try to imagine my comments are written for a skeptic – for someone who assumes I’m bad at my job and will want to rewrite my code.
If my comments can get the next developer into the same headspace as I was in when writing the code, then they are less likely to dismiss all my hard work and redo it just because they don’t understand it. In comments, try to demonstrate that, yes, you considered alternate implementations and this one you picked was reasonable and good. If that’s too hard, then maybe your implementation is not reasonable, or not good, or you don’t yet know enough to make that determination.
