This year a virtual contest environment will be provided to contestants in the form of an OVA Virtual Machine. It is based on Ubuntu 20.04, and contains the exact same compiler versions as those used on the judge machines, as well as a number of editors, IDEs, and other common programming tools. Its use is completely optional and only provided as a convenience.
The OVA for the virtual contest environment can be downloaded here:
Make sure you have at least 20GB of free space on your computer, or more to be safe. Import the OVA file into VirtualBox or another hypervisor of your choice. Start the nwerc2020-vm virtual machine and you will be automatically logged in as the team user. The user has sudo privileges, and its password is team. See below for frequently asked questions.
In addition to the compilers and interpreters listed on the Judging page, as well as reference documentation for all five submission languages, the virtual contest environment also includes the following software.
