For I/O-bound work, asyncio and threading both deliver roughly 10x speedup over serial code. For CPU-bound work, only multiprocessing bypasses the GIL — threading and asyncio actually add overhead.

When Git rejects your push with non-fast-forward or fetch first, the remote has commits your local branch does not have. Pull those commits first with git pull --rebase, then push again.

Generator expressions use ~200 bytes regardless of sequence size; list comprehensions hold every element in memory at once. Use generators for one-pass operations like sum() and any(); use list comprehensions when you need to iterate more than once, index, or check length.

This error means Python's JSON parser received an empty string, HTML, or a file with a BOM instead of valid JSON. Fix it by checking the input before calling json.loads().

This error means git found no common commit ancestor between your two branches and is refusing to merge them. Fix it by adding --allow-unrelated-histories to your pull or merge command.

The sqlite3 OperationalError: database is locked occurs when a second connection tries to write while another already holds an open transaction. The fastest fix is enabling WAL journal mode and always closing connections promptly.

Detached HEAD means Git's HEAD pointer is pointing at a commit SHA instead of a branch name. Fix it with git checkout main to go back, or git switch -c new-branch to save any commits you made in that state.

Use subprocess.run() for almost everything — it runs a command, waits for it to finish, and hands you the result. Reach for Popen only when you need to stream output line-by-line, write to stdin interactively, or check whether a process is still running without blocking.
