Happy New Years from Intel to all consumers: https://www.theregister.c ... tel_cpu_design_flaw/

As quoted:

"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 – specifically, PCID – to reduce the performance hit.

So, for those who enjoyed playing video games on PCs with Intel-based CPUs, be sure to note that some of you may be one of those users who will expect to experience performance drops. Of to what extent, I don't know, your mileage may vary vastly."

Hah, read about that, what a riot.

This is the first time I've had a computer now for nearly two years (built latest one in March 2016) and not had the itch to build another. It still smokes everything I play, and since all games seemingly need these days is a good GPU what's the point really?

Any reason to build anything new with what's coming down the line?

I don't see the need to constantly add the shiniest and newest CPU or GPU to my rig. It does what I need it to do.

Looks like it exists in some AMD chips as well now. Ther are already patches coming for Intel from MS and Linux.

Yeah, but they are software patches which is why the performance will take a hit.

Yeah I didn't realize that til after the fact. From what I've read since though it seems like the likelihood of it effecting most people is pretty small.

I believe the biggest performance will be felt on the server side of the house, especially with VMs.

Meltdown is limited to Intel chips, Spectre attacks Intel, AMD and ARM processors.

The more I read about this, along with becoming more cynical as I get older, is that this probably isn't a "bug" at all. I would bet at good odds that this "bug" is actually an NSA/CIA/whatever backdoor that existed for many years until somebody not in the know actually figured it out.

Call me a conspiracy theorist, but I highly doubt any of this was unintentional.

I mean Twin isn't wrong. Intel is known to let vulnerabilities in place in order to play ball with the NSA.

The last tech company to not play ball, the CEO got charged with insider trading.

It's pretty likely. When the Snowden leak happened it revealed a boatload of backdoors for the NSA hidden in all kinds of tech, but I doubt that was everything. Hell, they were physically taking people's laptop orders and loading their own spyware on them and then redirecting them to the people who ordered them.

I mean I don't see how we could, what with the inescapable gravitational pull from your moms ass and all.

quite possible but after reading https://danluu.com/cpu-bu ... gs/ -
it looks like a management problem. it's hardly ever the engineers.
complex architecture (like pre-fetching and executing instructions w/o any security checks in order to go faster) needs proper testing, not management buzz words.
it's a mishmash of things imo, from ever growing complexity of everything, to alphabet soup agencies.
also as people get smarter and get better tools, nothing designed in the past is ever going to be safe, regardless of the work practices (good and or bad).

What you mean, is NSA is masturbating along with millions of Americans as they masturbate. Or is it just NTAK?

Considering you've been playing in our servers for a very long time, I find it hilarious that you are acting surprised that fag and cunt are punished by the language enforcer. Considering plenty of people have gotten punished for using those words in the server.
Angry_Cuban13 18th Jun
I'll modify your ban from 14 days to 1 day as you didn't circumvent the language enforcer this time.

you can say whore bitch all that stuff but if you say cunt you get banned??? come opn

ok.. so i believe ive been banned again but this time i really didnt think id get banned for can you telll me the words i cant say
