Instructions, examples and implementation notes.
Choose a model for the work you need done
A faster model response can leave more checking behind. Compare two setups by the answers people can actually use, including time, cost and data restrictions.
Build a document assistant whose evidence you can inspect
Use a small local search script to select passages, hand them to a model, and distinguish missing evidence from a wrong answer or hostile instruction.
Navigate, edit and restore files in Linux
Work with paths, directories, files and links; edit a small file, keep a backup and understand deletion.
Read and transform Linux text with pipelines
Turn six practice log lines into per-route error counts, watching what each command keeps, removes and passes to the next.
Find what blocks a Linux file before changing its permissions
A readable file can still be unreachable. Use two small experiments to see how Linux checks your account, the file and each directory on the way.
Follow a Linux process from launch to exit
Find running work, inspect exit codes and environment variables, and stop a process deliberately.
Install software and preserve its configuration
Install the software, start the process and serve one practice file. Then change its port to see which settings the running program actually uses.
Run a Linux service and follow its startup trail
Move the practice web server out of your terminal, trace a request through its logs, and repair a launch command that points to the wrong executable.
Explain Linux storage usage before removing files
Deleting a large file may leave a write failing. Compare two equally long lab files to see what uses storage, then see why removing a name may leave an open file occupying space.
Separate DNS, listening ports and HTTP failures
Follow one request from name lookup to the listening server and its HTTP reply. A missing page, refused connection and failed lookup tell different stories.
Connect to your Linux lab with SSH
Use a dedicated login key, recognize your VM before signing in, and follow a failed connection to the stage where it stopped.
