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?

The Privacy Tax

In the 1980, privacy was a lot easier to acquire. Banks can harvest information on us, but the limited computer power was a big limiting factor to their analyzing dreams.  For years Banks have computed the best credit options (for them) to sell to customers.

Come farsi buttare fuori

Sembra che il governo a trazione “Legista Stellare” voglia farsi buttare fuori dall’Europa. Show come la scarpata di Ciocca oppure sperare che la Russia ci paghi il debito, sono goffi tentativi di nascondere una incompetenza notevole, che peraltro traspare da pasticci multipli, manine e altro.

Effetto Spread

Sembra che questo governo non tranquillizzi proprio i mercati. Il grafico BTP Italia/BUND 10 dell’ultimo anno…   Mostra chiaramente che il governo giallo-verde tiene nervosi i mercati. Se giocate in borsa, forse è il caso di non perdere di vista i vostri investimenti finanziari, ad Agosto
