Default Google: Our brilliant Spectre fix dodges performance hit....

....so you should all use it. From ZDNet:

Google wants the whole industry to adopt its Retpoline fixes for Variant 2 of the Meltdown-Spectre bugs.

Google's 'moonshot' fix for the hardest-to-solve of the three Meltdown and Spectre CPU attacks seems to have paid off.

Question Re: Google: Our brilliant Spectre fix dodges performance hit....

Well I might have used it if had half a clue as to what that load of tosh meant. "Moonshot, Meltdown and Spectre." What on earth has all that lot got to do with me reading facebook or any of the other tasks that I carry out on my computer. And as for this, “Out of the eater came forth meat, and out of the strong came forth sweetness”

I still have little idea about this problem or what we (the users) are supposed to do about it!

The only bit that I have read about the problem that I have understood is the explanation of it in the latest issue of CA (no 519) although even that article does not tell us what to do about it!

I've almost given up on the Biblical puns as there are few people nowadays who can recognize the quotations, which is rather sad. They go straight over most peoples heads. This one is Samson's riddle (Judg. 14:14).

So are we meant to pray that MS gets the patch right or hit the computer with an Ass's jawbone ?

The 2nd option would be very tempting for all kinds of computer problems Tom, if one only knew where to get an ass’s jawbone from! An answer to the riddle:

What’s the answer to this riddle: Out of the eater came forth meat, and out of the strong came forth sweetness? | Yahoo Answers



As for the Meltdown/Spectre issue, I think the only thing to do is to keep everything up to date and install relevant patches as soon as they’re available.

More about the Google fix:

Google: We fixed Spectre and Meltdown with no performance loss - SlashGear
Quote:
By using Reptoline, Google was able to modify programs directly, meaning that it didn’t need to modify hardware and could therefore avoid the slowdown that would come with those modifications. Google says that in testing Reptoline, it found that it was able to patch against Spectre Variant 2 with “almost no performance loss.”

Even better news is that Google has open-sourced Reptoline so that other companies can take advantage of it in their own Spectre fixes. It closes today’s blog post by stating its belief that Reptoline is currently the best solution for patching against Variant 2, so hopefully now that Google has made it available to its industry partners, we’ll see wide-scale roll out.
If this is correct, it's very good news for all of us.
