sudo sh -c 'echo 0 >> /proc/sys/kernel/kptr_restrict'
sudo sh -c 'echo 0 > /proc/sys/kernel/nmi_watchdog'
sudo sh -c 'echo -1 > /proc/sys/kernel/perf_event_paranoid'
echo 1 | sudo tee /proc/sys/kernel/sched_schedstats

Rust Workshop set-up instructions

Hi, these are the setup instructions for the rust workshop. This is the (hopefully) bullet-proof way to get everything you need for Thursday (and still have it working on Thursday). If you run into issues, check the FAQ section.

Note: If you don't like to use Docker, see below for an alternative method.

Install Docker itself if you don't have it already

• Mac installer
