Windows 10 Hyper-V Ubuntu Can’t Connnect when Enhanced Session is Enabled – Blue Screen
I've recently been toying around with the Quick Create in Windows 10 Hyper-V and I noticed that I couldn't connect once the VM was created if I chose to connect using an Enhanced Session. As it turns out, if you enable auto login during the setup of the Ubuntu VM it will not let you remotely connect using any option you have. It just gives you a blue screen. Make sure this option is not set to auto: If you have already set that setting to Log in automatically and you want to … [Read more...] about Windows 10 Hyper-V Ubuntu Can’t Connnect when Enhanced Session is Enabled – Blue Screen

Lose your LAMP, MAMP, or WAMP dev environments and start using Koding

At first I was using a WAMP install, but eventually put my work on a linux VPS within my … [Read more...] about Lose your LAMP, MAMP, or WAMP dev environments and start using Koding
