Network basics
- Networking is a big part of what made computers so powerful and why the Internet exists. It allows machines to communicate with each other.
Docker
Let's first pull a Docker image and run a container:
Note that docker command will pull the Ubuntu docker container image from the Internet and run it. I let you look at the meaning of the flags using the command docker run --help, the main idea is that it keeps the container up and running.
To execute a command on the Docker container, use *docker exec*:
If you want to connect to your Docker container and use Bash, you need to use *docker exec -ti*:
If you want to stop a container, use *docker stop*:
Web stack debugging
- Intro
- Debugging usually takes a big chunk of a software engineer’s time. The art of debugging is tough and it takes years, even decades to master, and that is why seasoned software engineers are the best at it… experience. They have seen lots of broken code, buggy systems, weird edge cases and race conditions.
Test and verify your assumptions
- Debugging is fun
- Debugging can be frustrating, but it will definitely be part of your job, it requires experience and methodology to become good at it. The good news is that bugs are never going away, and the more experienced you become, trickier bugs will be assigned to you! Good luck 😃
