If you're looking to use the HACKS platform (where the labs are in the cloud), then all you need is an up-to-date modern web browser (IE 10/11+ or recent Safari, Firefox, Chrome) on any Operating System. Now, if you're planning to run the labs locally, through our downloadable VMs - then the specs we suggest are a little more comprehensive.
Optimal specs for VM lab-work:
A dual core (i5/i7 or equivalent processor, 8GB of RAM, 500+ GB Hard Drive [solid state drive preferred]) system is recommended.
Operating system can be Windows, Mac OS X, or Linux.
To run the VMs - we recommend Oracle VirtualBox (free), or VMWare Workstation/Fusion (costs money) to actually virtualize the VMs.
