#+title: How I Work
|
||||||
|
|
||||||
|
I work primarily within [[file:20200711111302-emacs.org][Emacs]], typically with a Chromium web browser and/or a
|
||||||
|
terminal emulator alongside it, and Slack and/or other messaging apps on another
|
||||||
|
screen.
|
||||||
|
|
||||||
|
* Coding
|
||||||
|
- Navigating projects and source files using Projectile.
|
||||||
|
- Staging and committing changes with Magit.
|
||||||
|
- Running integrated code formatters, linters, and test runners.
|
||||||
|
* Writing
|
||||||
|
- Maintaining a work journal with [[file:20200710214307-org_mode.org][Org Mode]], taking meeting notes and keeping a
|
||||||
|
record of how I accomplish non-coding work like troubleshooting issues.
|
||||||
|
- Documenting things as I go in [[file:20200710141321-org_roam.org][Org-roam]] and exporting them to Confluence when
|
||||||
|
necessary.
|
||||||
|
** Including shell commands, http calls, sql queries, and their results in my notes

||||||
|
** Including graphs and diagrams
