Useful Notes

Being in control of Environment parameters

• Using environment modules
• Aliases and local variables
• Setting local variables
• Set a custom temporary directory location
• Installing R packages locally
• Setting up and using a virtual environment for Python3
• Locale_settings (how numbers and dates are displayed)

Controlling costs

• using SACCT to see your costs
• using the "get_my_bill" script to estimate costs
