Intel

A fundamental design flaw in Intel's processor chips has forced a significant redesign of the Linux and Windows kernels to defang the chip-level security bug.

Programmers are scrambling to overhaul the open-source Linux kernel's virtual memory system. Meanwhile, Microsoft is expected to publicly introduce the necessary changes to its Windows operating system in an upcoming Patch Tuesday: these changes were seeded to beta testers running fast-ring Windows Insider builds in November and December.

Crucially, these updates to both Linux and Windows will incur a performance hit on Intel products. The effects are still being benchmarked, however we're looking at a ballpark figure of five to 30 per cent slow down, depending on the task and the processor model. More recent Intel chips have features - such as PCID - to reduce the performance hit.

That's one hell of a bug.

You asked a question, I (we) replied, why are you getting angry ?

First of all, how do you know I am angry?

Second, it isn't the replies to my question that I was referring to. Given that you couldn't see even that, refer to the first point. ;)

"[q]Apparently some people on this site don't like it when you ask an earnest question because you don't know something.

Sorry, next time I'll pretend to know everything.

I'd say your sarcastic tone is revealing of your true self. Now pretend whatever you want to feel right.
