Voglio raccontarvi una storia, per spiegarvi quanto è difficile conciliare la vendita di un prodotto commerciale con lo sviluppo di un software "open". Al giorno d’oggi le calcolatrici scientifiche sono un mercato con parecchia concorrenza, e lo prenderò come esempio.

Some time ago I stumbled upon this Hacker News discussion on how disable Spectre mitigation.
