Re: Intel Processor bug incoming?

that said, I don't really follow what you are saying. It all seems very muddled and confused to me, and the only part that I can pick out is that you seem to distinguish between being able to read kernel memory and so forth *outright* (from userspace) and the ability to piece together, by bits and ...

Re: Intel Processor bug incoming?

It is quite possible that is a flaw from the x86 ISA itself. Well, if you had read the technical discussion you would know that's completely wrong. And it would be rather strange for ARM64 to have similar patches posted in November. Which I linked above. In fairness, he could be referring to the In...

Re: Intel Processor bug incoming?

Blech. This looks like it could have a large impact on servers/VM farms. Someone really screwed the pooch at Intel if this can't be fixed via microcode. It can't. The positive spin for Intel is that the fix, at least as implemented in Linux, also prevents certain other (much less severe) attacks on...

Re: Intel Processor bug incoming?

Note that the Phoronix benchmarks are not "clean" and include a bunch of updates, not just the Intel PTI bug fix. Theoretically, we could have all sorts of performance improvements that are masking some of the effects of the bug fix. It's likely that any such effect is very small, but we j...

Re: About Acer Laptops...

The world of laptops is more similar to your home appliance story than you might think. Not only are the majority of innards made by the same companies (Intel, AMD, NVIDIA etc), the actual laptops themselves are often made by a so-called ODM. These are companies that specialize in putting together c...

Maybe once the Flash.exe is in effect, the number of adds doesn't add to the CPU overhead. NO, this is most definitely NOT the case. The *bug* present in the flash ads mentioned here is additive.

Flash doesn't use graphics card at all. It's 100% dependent on your CPU. That's why it slows down low end machines.
