Meltdown, Spectre: The password theft bugs at the heart of Intel CPUs

Re: Some real world results

"YMMV"

Pretty much what Linus said. If you don't make many kernel calls (computationally intensive, in other words) you shouldn't see much. If you make a lot of kernel calls then you get hit. It's the userland/kernel/userland transitions that are slowed down.

You raise an interesting point. Try mitigating this on a quantum computer taking all branches simultaneously.

Now if we had some decent people at the W3C we would see Javascript being phased out them being ignored

Re: " don't run untrusted code"

"Disabling Javascript totally rather breaks the interwebs these days."

Most of the time I'll simply ignore a site that won't work at all without Javascript. If I think I really need it I'll see if I can selectively enable enough domains to make it work or see if the Google cached version is sufficient. Some sites manage to use so much Javascript as to break on some browsers even when fully enabled; eBay, I'm looking at your recent inability to display images in Seamonkey.

Proposed Brit law to ban b**tards brandishing bots to bulk-buy tickets

Doctor Syntax Silver badge

It's not an area that greatly concerns me but from the descriptions I've read here I'd have thought existing fraud legislation might have dealt with a lot of it and has the added advantage of imprisonment as a deterrent. But introducing a new piece of legislation is easier for legislators than getting existing legislation enforced. Which raises the question of how the new legislation will be enforced.

Re: Prioritising the priorites

Government is responsible a lot of areas and not all the public have the same concerns. If the entire government machine was obliging you, Stuart, by concentrating on what you think they should be doing there would be a lot of other people complaining about neglect of other issues such as Xylella fastidiosa or asking why you left climate change or whatever off your list.

Kernel-memory-leaking Intel processor design flaw forces Linux, Windows redesign

Doctor Syntax Silver badge

"It depends on what's going on in a system."

Firing up top in Linux shows several processes, mostly daemons, actively using CPU with nothing actually being done with the system so even in the absence of IO there's context changes taking place even if it's just a matter of waking up daemons to find that there's nothing to do. I'd guess that much the same situation applies with Windows.

Re: Phew!

"So you think the security problems in the world don't matter other than the influence of which processor you buy"

Focus. Tackle each issue in its own place. We've discussed other security issues in other contexts. Actually, in this context, the issue isn't so much the security issue, because like many others, it can be fixed, but the cost of fixing it.

I'd have thought that something computationally intensive would be least affected as it would make fewer syscalls.

Re: Hmmm...

There are already plenty of non x86 derivatives out there that don't have this bug, all that's required is for vendors to make them as readily available so as to enable folks to make the move. :)

Just starting to think about a laptop replacement. Looked at PC Specialist. Not an AMD in sight.

Doctor Syntax Silver badge

Apart from the hit on performance what's the likely effect on power consumption and hence battery life and heat generation? Clearly the CPU is going to have to do more work to achieve the same result.

Re: Tax Laws

"If you have a small indigenous economy ....

But we don't."

Exactly. If you're managing the Irish economy, say, you can gain more by bringing in large multinationals at low tax which is why Ireland do that. If the UK were to cut tax rates to tempt multinationals away from existing low tax areas they'd be unlikely to bring in more than they'd forego from existing UK businesses.

It's an international market place in taxation. The pile-it-high-sell-it-cheap approach only works if you don't have too much to lose from your existing domestic tax base.

Doctor Syntax Silver badge

Re: Tax Laws

"If governments want these businesses to pay more tax, they have to change the tax rules."

It's not that easy.

If you have a small indigenous economy you don't have that much to lose by inviting in multinationals by offering low taxation. What's more those indigenous businesses gain off the back of it by being lightly taxed. If you have a large economy the tax lost by taxing those lightly offsets the gains obtained by binging in those large multinationals. It's a trade-off. What you see happening is complaints about not being able to compete in what's in effect a free market in taxation of multinationals. Governments, as usual, wanting their cake and eating it.

Of course it's solving a problem. It's just the vendor's problem (what can we sell?) and not one of the user.

"As Khosla put it: "Most of these [data gravity causes] are not critical issues for 'once a year data anti-gravity' threat that CIOs need to hold over cloud vendors' head. "

From the original linked blog post:

"Data is the most massive and dense, therefore it has the most gravity. Data if large enough can be virtually impossible to move."

The second sentence sounds more like inertia than gravity.

Presumably double-quote is where it normally is, shift-2. Is that the period on the / key? Confusing if it is. But for something intended to run Linux where have \ and | gone?
