Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'отлаживать' (otlazhivat') is the precise technical term. 'Исправлять ошибки' (ispravlyat' oshibki) is a more general paraphrase.
- Do not confuse with 'дебаггер' (debugger), which is the tool for debugging.
Common Mistakes
- Using 'debug' as a noun (e.g., 'run a debug'). Correct: 'run a debug session' or 'do some debugging'.
- Confusing 'debug' with 'test'. Testing finds problems; debugging fixes them.
- Misspelling as 'de-bug' with a hyphen is now archaic.
