IDG NEWS: There is lots of information circulating about the new exploits of computer chips from Intel and others announced in the past few days. Some of it has been accurate, and some has been sensationalist and overblown. There is much technical information with high level of details available for both Meltdown and Spectre, so I won’t get into a lot of technical detail here. Rather, I’ll focus on the higher-level issues affecting business and personal computer users.
