Even this PoC was limited to 2000 bytes a second; even a little noise may well render the attack largely theoretical - or at least make the attack so slow as to make it feasible to use other (expensive) mitigations only very rarely. But yea

The attack is pretty brilliant; but it's also not quite novel. Cache-timing attacks aren't new; certainly CPU suppliers should have known the general issues at hand for... at least a decade? See e.g. Colin Percival's somewhat

Talk is cheap; investing perhaps less so. The asserted "soaring" stock price simply hasn't happened. The 7% rise they name as "soaring" is not a soar for a stock this volatile: https://www.bloomberg.com&

That's what you're saying (and indeed what I said too!), but that's not what bloomberg published. What you're saying makes sense! But they didn't qualify this by major . And the qualification is important to t

So... How is this exactly a silver lining? Avoiding fixed costs is a means to an end, not an end in and of itself. And that end (actually saving money/increasing efficiency) just receded further away. And hey, nobody actually knows

This piece is (IMNSHO) trash. It's trying to stare into some crystal ball guessing at the cause of market fluctuations; but there's no real evidence they're right. Not to mention it's pretty misleading about technical s

Technically, I suspect they could easily make em last 10 years without too many drawbacks. And if you're willing to be a bit more compromising, much more even than that. But why engineer that kind of life expectancy into a device tha

If by "fundamental battery issue" you mean that all phones have this issue or some comparably severe tradeoff, then no, this is not a fundamental issue. Batteries don't all degrade at the same rate, and even given a specif

To be fair: the OP didn't merely ask, he also gave a subjective opinion on the matter; and it looks like the response was to that, and not related to the battery expertise bit. But hey; in an online forum things get off topic... kind o

by emn13 9y ago
It depends on lots of factors; but the degradation can be a lot more than that if you really abuse your battery. And unfortunately most devices don't make it easy to avoid being hard on your battery - you just kind of need to know wha

Yeah, I think the rule is overzealously applied, not sure it's necessary in the first place. But let's have that debate based on reality rather than imply something worse is going on, when it's not. (Personally, I think the

It's misleading not because it's false (it's not!), but because it's selectively leaving out context. The original title is better. I'm not saying there's no free speech dimension here, just that the original

I think this is a misunderstanding of what's going on here. The issue isn't hiding away messages - notably you can still find whatever they're saying fine, the ban only applies to public speaking events. The point is that pa

by emn13 9y ago
This title is misleading - can it be corrected to the actual title of the article? Because at issue isn't any ban on free speech, it's whether it's OK to ban invited speakers expected e.g. to incite harassment, bigotry, or vi

That's not really fair at all; given that accounting for size differences really barely nudges the needle - and grey money is likely a factor in US elections too. I can't find a single very trusted source for US spending, but vari

Simultaneously, capitalism doesn't work entirely with fully informed agents. Any amount of privacy undermines its efficiency. Frankly, talking in extremes like that isn't likely to be helpful in deciding which regulatory agency s

Just look at the amounts involved however - the UK is orders of magnitude better. Ignoring differences of degree like that is a sure way to end up in a terrible situation: "it's bad anyhow, who cares if it gets worse?"

I'm sure they correlate: but the thing with correlation is that you can have correlation even when there are whole classes of situations where the relationship doesn't hold. On the same os +drivers I'd be willing to believe t

I will gladly believe this is a real problem, but this page does not demonstrate that (at least not convincingly); the metric used is simply too poor. To quote: > I used my own hacky measurement program written in C++ that sends a keyp

The physical silicon is almost worthless. What's valuable is how you can use it; and there too I suspect "you don't own it" is hyperbole - but perhaps not entirely, given all IP involved. What's certainly not hype

Only if those 5 suicide bombers would not have otherwise committed a similar act - it's not clear to me how the stated aim or allegiance behind such acts is related. Is that a cause? An effect? Something more complicated? But yeah: ni

Considering women innocents (I'm assuming you mean non-combatants) is pretty absurd, IMHO. As in: they're certainly aware of what they're involved in; and their participation contributes significantly to the problem, and to t

Come on, that's a strawman - you know that. It's not like there was a briefing with two options: mass murder, or let the bad guys retreat: pick one. Nor are the causes of "the whole mess" that trivially pinpointable.

You do realize that e.g. the US spends approximately as much on the DHS (which is primarily borders+immigration stuff) as on the FBI, CIA, NSA, DEA and FBP (federal prisons) combined? And that's the US, which through history and geogr

I think a high reserve price is actually a really neat idea - you'd think that might have the knock-on consequence of reducing the attractiveness of adblockers, and furthermore of reducing viewer fatigue (so that the ads you do show ha

Definitely. But the parent poster I was replying to was suggesting you could do it merely with cash in hand - and that's not going to be doable. I mean, I'm not saying the scenario is particularly realistic: it's an absurd h

They'd probably have to pay taxes to repatriate that cash to buy those firms, however, and buying a firm has costs of its own (not just overheads, but you obviously need to pay more than the market cap usually). So this amount is well

That's great news! I used to buy the old z[123] compact series, but that glass back... I've got kids and it just doesn't work anymore. A phone needs to have some modicum of robustness to be useful. The ancient, crappy look
