Please note that the Power Point slides have notes below which are not visible during regular presentation. These notes typically contain useful remarks and links to related work so do not overlook them.

Practicals

There is no special software required for this course, only a general IDE (consider using Visual Studio Code), SSH terminal, and any tool capable of SFTP/SCP file transfers. You will be given account on our server Webik, where you can deploy and debug your assignments. Optionally, you might want to consider installing web server (e.g., Apache) PHP, Nodejs, and MySQL database system on your computer as well.

There are practicals ("cvičení") currently scheduled in SIS + one virtual lab (not scheduled). Make sure you are enrolled to one of them and do not change your lab after the semester begins. The virtual lab is designated for students who either repeat the course (and actually did some nontrivial work in the labs last year) and students with special needs.

Most of the assignments will be only in ReCodEx. Each lab will have associated group in ReCodEx. If you have any trouble accessing the ReCodEx or you experience problems with the assignments report to your racticals/labs teacher(s).

Attending practicals is not mandatory, yet strongly recommended, see grading. Bellow you can find materials used in practicals/labs.
