Your Phone is your (next) Personal Computer
On this Christmas, a lot of us will pay more then $1000 for a new iPhone XY or for a similar Samsung one (twice the price of a netbook) and you will have in your hand a quite powerful machine: for instance iPhone used as Theorem Prover is faster then an Intel Workstation (!) It is …
Hyper VM Troubleshooting
Sometimes your winwos’ HyperV Hypervisor will refuse to start. The problem is tricky because the services seems started if you check them. Also the installation is successful, virtualization is enabled and so on. So what is wrong?
