How to Build a Computer 39: Epitaxy II: The Reckoning


I know y’all have been waiting eagerly with your wafer in the chamber, the temperature pumped down and your native oxide layer stripped off for me to finish this two-parter. Well, wait no longer! Okay, maybe wait some as you have to find a tank of dichlorosilane to hook up so you have something to epitax onto your wafer. Di-what now?

Jim Geraghty of National Review and Greg Corombos of Radio America enjoy watching the Russians get barred from competing in the 2018 Winter Olympics because of an ongoing doping scandal, and they also get a kick out of the International Olympic Committee suddenly caring about corruption.  They also shake their heads as Steve Bannon tries to discredit Mitt Romney’s denunciation of Roy Moore by saying Moore served in Vietnam and Romney avoided it by “hiding behind his religion.”  And they scold Arizona  Sen.

Few countries do indignation as well as they do. http://www.foxnews.com/world/2017/12/05/russia-banned-from-2018-winter-olympic-games-in-south-korea-over-doping-scandal-ioc-announces.html Preview Open
