Again sorry for the short blog post but this is such a great resource I thought I would be a shame to not mention it
I have picked up a few gems from here such as vCenter, Horizon View and stuff for my Raspberry Pi. Remember to check back daily though!
If you want some free Microsoft bits I suggest going here.
There are some great guides for select use cases.
And finally VMworld 2016 sessions… this year they are free to all and I suggest setting aside some time and going through them. I am repeating some as learning little nuggets each time.
