Choose an answer:

Immediately downloading all images from the website. Sending a request to a server associated with that URL, asking for the webpage's content. Checking your computer for locally stored copies of the website. Executing Python code directly within the browser.

Considering commands for undoing changes like `git reset --hard <commit>` and `git revert <commit>`, what is a critical difference in how they affect project history, especially when dealing with commits already pushed and shared with others?

Tutorial: 01-first-contribution

Difficulty:

Hard

Tags: git commands reset revert history shared-branches safety

Choose an answer:

`git reset --hard` is safer for shared history as it just moves the HEAD pointer, while `git revert` deletes commits. `git revert` creates a new commit that inverses the changes of a previous commit, preserving history, making it safer for shared branches. `git reset --hard` discards commits and rewrites history, which is dangerous for shared branches. Both commands rewrite history; `git reset --hard` is for undoing staged changes, and `git revert` is for undoing committed changes. `git revert` can only undo the very last commit, while `git reset --hard` can undo multiple commits.

When calling a reusable workflow in GitHub Actions (`uses: ./.github/workflows/reusable.yml`), if the reusable workflow (`reusable.yml`) defines a matrix strategy, and the caller workflow also defines a matrix strategy, how do these strategies interact for the jobs within the reusable workflow?

Tutorial: 01-first-contribution

Difficulty:

Impossible

Tags: github-actions reusable-workflows matrix-strategy ci-cd advanced-workflow yaml

Choose an answer:

The caller's matrix strategy completely overrides the reusable workflow's matrix strategy. The reusable workflow's matrix strategy is ignored; only the caller's matrix applies to the jobs it defines directly, not the jobs within the reusable workflow. The two matrix strategies are combined multiplicatively, creating a job run for every possible combination of matrix values from both the caller and the reusable workflow for the jobs within the reusable workflow. This scenario is not allowed by GitHub Actions; a reusable workflow cannot have its own matrix strategy if the calling workflow also uses one, leading to a validation error.

In the context of a GitHub Pull Request, what is a key benefit of linking your PR to an existing issue (e.g., using 'Closes #123' in the PR description)?

Tutorial: 01-first-contribution

Difficulty:

Medium

Tags: github pull-request issues workflow collaboration automation

Choose an answer:

It automatically assigns you more GitHub achievement badges. It provides context for your changes, helps track the progress of the issue, and can automatically close the linked issue when the PR is merged. It prevents anyone else from commenting on the original issue. It ensures your Pull Request gets merged faster than others.
