Software devs, how have you sped up your workflow?
2 by potatopotahto | 2 comments on Hacker News.
Lately I've been paying attention to where I spend time and I've managed to find some low-hanging fruit and optimize some tasks. Examples like using fish (unix shell), writing shell scripts to automate sequential build commands I'd otherwise have to wait for, learning vim shortcuts and language syntax, implementing reusable utility scripts to produce/consume data. Do you have recommendations/tips/examples to speed up your processes? Feel free to share even specific instances, they don't have to be as generic as above.
