Seven Useful Programming Habits for Developers

Bartlomiej Karalus , currently a Senior Web Engineer at Zonal, shares the programming habits he has cultivated over his career (original article translated by Wei Jia).

He reflects on habits that intersect both personal life and work, focusing on practices that directly improve coding efficiency and well‑being.

Uncontrolled autosave – Even though modern IDEs auto‑save, he still habitually presses Ctrl+S whenever he stops typing, a reflexive action he finds hard to break.

“Rage mode” with scheduled breaks – Intense bursts of productivity are valuable, but he emphasizes the need for regular “pit stops” (rest and recovery) to prevent mental fatigue, similar to an F1 race.

Eliminate all distractions – When tackling critical tasks, he turns off his phone and blocks social media, acknowledging that extreme measures (like locking kids in a basement) are not advisable.

Define expected outcomes before starting work – Visualizing and measuring goals helps him create a clear daily checklist and reduces feelings of futility at day’s end.

Maintain regular training – Consistent fitness and coding practice keep his “saw” sharp, yielding long‑term benefits even without immediate rewards.

Test‑first approach – Writing test cases before implementation clarifies objectives and aids design and documentation, though many developers overlook this practice.

Avoid over‑future‑proofing – Early attempts to perfect code for every edge case lead to unnecessary complexity and wasted time; embracing simplicity is more effective.

He hopes readers can adopt these habits, emphasizing that the only way to build a good habit is to start practicing it, and invites others to share their own useful habits.
