all take with a pinch of salt until Kernel 4.15 rolls out bah

as for me: i'll twiddle my thumb until Mint 19 or 18.04LTS bah

(but my money is on no impact whatsoever on my media pc )
Me using a self-built kernel 4.5 which I have no intention of ever updating or recompiling until another two or three years.

By then we will have moved on to kernel 5.x already.

Intel CEO has inside intel for being inside intel and sold of 24 Million worth of stock in november.

Google has informed Intel months before it's CEO decided to get rid of part of his shares. And finally the bug came to light and intel's stock prices plummet...

Intel is as shady as ever. This is basically insider trading and highly illegal.

On the other hand, Microsoft patch has been pushed out. Intel need to push out a firmware update to fix the issue completely. There seem to be no performance hit on games according to recent Hardware Unboxed youtube video testing the latest patch on Intel's i7-8700K.

The key executives can change their position on their shareholding. It's just that they need to do the relevant paperwork filing to the relevant securities exchange. In this case, the relevant SEC filing and presumably he did follow the standing order except the internet can spin it out of context.

I'd take the verbatim quote as half correct.

But overall he won't be sitting there for long, there's a reason why the ex. Qualcomm dude became Intel's $25million man.

so in other words the patch is only from Microsoft side and not intel's bug fix?

Kernel is affected thus Microsoft Windows, Linux and Apple's MacOS needed to be patched. Intel also needs to push out some sort of firmware/bios microcode too it seems.

Intel's official statement has so much crap. Thankfully, TheRegister has translated the crap statement to be truer. Such a good read.

Article: "We translated Intel's crap attempt to spin its way out of CPU security bug PR nightmare"

Most consumers will not be heavy kernel users and hence not materially affected by the patch (when it comes from Microsoft). Interesting read from the Register.

I was reading on reddit (a day before Google PR release/2nd Jan) that it would have more drastic effects on heavy I/O users, i.e. cloud providers, i.e. MS Azure, Google, AWS etc.

The intel problem is a security issue with the cpu switching into kernel mode and user mode.

If the spectre issue is interpreted correctly, it is a fundamental problem with how modern CPUs do branch prediction, prefetching (basically doing things the efficient way) in hardware. All the key vendors are affected because they all use some of these modern computing techniques to make the CPUs run faster if people looked at the research paper. Can't single out any vendor on this one and it will be a pandora's box.

It will take literally years for this to be completely mitigated in hardware at least.

Well precisely, wait for the response. Pertaining to 'spectre' the only solution is to wrap your smartphones, laptops and computer in tin foil but don't scream when we all get wifi/bt attenuation issues and check again if the sky is falling is it ?

So overall tl;dr: they're out there and they're going to get us correct?

Link to the latest Windows 10 Build 1709 patch that solves the issue.

https://support.microsoft.com/en-us/...date-kb4056892

  • Addresses issue where event logs stop receiving events when a maximum file size policy is applied to the channel.
  • Addresses issue where printing an Office Online document in Microsoft Edge fails.
  • Addresses issue where the touch keyboard doesn’t support the standard layout for 109 keyboards.
  • Addresses video playback issues in applications such as Microsoft Edge that affect some devices when playing back video on a monitor and a secondary, duplicated display.
  • Addresses issue where Microsoft Edge stops responding for up to 3 seconds while displaying content from a software rendering path.
  • Addresses issue where only 4 TB of memory is shown as available in Task Manager in Windows Server version 1709 when more memory is actually installed, configured, and available.
  • Security updates to Windows SMB Server, the Windows Subsystem for Linux, Windows Kernel, Windows Datacenter Networking, Windows Graphics, Microsoft Edge, Internet Explorer, and the Microsoft Scripting Engine.
EDIT:

Windows Client Guidance for IT Pros to protect against speculative execution side-channel vulnerabilities

This page has instructions on how to test if your system is affected using a PowerShell script.

Noteably,

Warning

Customers who only install the Windows January 2018 security updates will not receive the benefit of all known protections against the vulnerabilities. In addition to installing the January security updates, a processor microcode, or firmware, update is required. This should be available through your device manufacturer.
Just applying the patch isn't the fix until processor microcode or firmware is updated either through Microsoft update or BIOS update by intel/manufacturers.

Not just cloud providers but data centers in general. Like you said, heavy I/O users.

Anyway, I just installed the patch and no noticeable performance difference in general usage.

According to Microsoft, the patch isn't the end of it. More info can be found in the above link i edited in.

Warning

In addition to installing the January security updates, a processor microcode, or firmware, update is required. This should be available through your device manufacturer.
And yea, normal usage as a consumer, we wouldn't notice the performance deficit but mainly the Data centers are the ones who have to worry about it.
