Improving Programmer Efficiency: Keyboard Skills, IDE Shortcuts, Shell Mastery, and Multi‑Language Practices
The article stresses that programmers boost efficiency by mastering touch‑typing, IDE keyboard shortcuts, powerful shell terminals and custom scripts, while learning multiple languages to pick the right tool for each task, and maintaining curiosity and determination to continually refine their workflow.
There is a saying that "speed is the ultimate weapon" in martial arts, and similarly programmers need high work efficiency to thrive in the ever‑changing IT industry.
The author enjoys various methods to boost personal productivity and shares several practical tips.
1. Solid keyboard fundamentals : Use standard touch‑typing techniques. The author recommends typing practice sites such as 10FastFingers and typing.io , which help programmers improve speed and accuracy.
2. Master IDE shortcuts and features : Choose a comfortable IDE (e.g., Visual Studio for C#, IntelliJ for Java) and learn to operate it mostly with the keyboard. Shortcut keys for refactoring, inline extraction, and conditional breakpoints can dramatically reduce mouse usage. Tools like ReSharper (for Visual Studio) further enhance productivity.
3. Proficient use of a shell terminal : Command‑line interfaces are far more efficient for many tasks than graphical tools. The author recommends iTerm2 on macOS and Windows PowerShell on Windows for their rich features.
4. Ability to write shell scripts : Beyond using existing scripts, writing custom scripts automates repetitive actions. Examples include a directory‑alias tool ( gtshell ) and PowerShell scripts that start FTP servers or switch projects quickly.
5. Multi‑language programming : Knowing several programming languages (C#, Java, JavaScript, Ruby, Python, Groovy, Haskell, etc.) allows developers to choose the best tool for each problem. The author cites real‑world uses such as a Ruby plugin for blog synchronization, Groovy for faster test writing, and Python with WebDriver for forum automation.
6. Keep curiosity and a strong determination to improve : Observing highly efficient peers—such as VIM masters or developers who refactor code with a few shortcut keystrokes—motivates continual learning. Sharing useful tools (e.g., SuperPutty with multi‑tab support) within a team helps everyone become more efficient.
Ultimately, high efficiency frees the mind from repetitive chores, allowing focus on more valuable, creative work.
