Spectre and Meltdown
 
anyone worried about these? i heard the patches for these design flaws will slow down your processor.

This affects all computer chips since like the 90s, and also android phones

Meltdown is specific to Intel processors, and is much worse than Spectre.

Not particularly concerned since they were already working on patches when it was leaked to the public.

Steve Gibson spoke about this at length on several of the Tech TV podcasts. He has written a free program (In Spectre) that you can run to check the status of your system:

This will notify you if the patches may be slowing your computer. It will even change the registry to disable the patches, if desired.

Yes, you can use Steve Gibson's InSpectre program to disable the patches, if desired. For example, you may see a larger impact on PC performance as a side effect of the patch.

They already have to be in your computer to use either hack. Spectre and Meltdown just let them do more damage once they're in.
