+
+ Today the following packages were installed:
+
{% for item in list_package_installs %}
- {{ item }} {% endfor %} + + Packages are often installed to use different software or coding languages or build alternative tools. Often users have to talk about and consider which packages they need and why, as well as how much storage they take up and how they will change their interactions with and on their shared server. +

-

tldr@chopchop:~ $ grep 'remove' /var/log/dpkg.log-
-
+
+ These package were removed today:
+
+
- {{ item }} {% endfor %} + + Packages could be removed because of consuming too much storage, not being used by the people who share the server, or they are no longer secure. It is often good practice to 'do some spring cleaning' every now and then and remove the packages that no longer serve you any purpose. +

+
+ Users can login to the server using the SSH (secure shell) protocol. This allows a user to explore files, make changes, run commands and speak to the server from their own machine. This is useful when working remotely, and also to allow multiple users logging into the server simultaneously. Current XPUB1 students have a chopchop user, as well as the tutors. Additionally, there are some users not associated with a person, like our shared user 'chipchip' and users for running specific processes or creating projects.
