The crypto(graphy) is rarely the weakness in these situations, so declaring faith in (insert new tech buzzword here) is almost certainly not going to be the answer. It comes down to operational and human factors, like poorly written code.

You can't look at a chart of an index price and simply say "it's down from the peak, I would have lost money". If you do that, you are forgetting that stocks pay dividends, and they aren't included in the index pric

Since the article is being pedantic, here's another pedantic complaint: What if printf() can't write all of its output, but manages to write some of it? printf() returns the number of bytes written, but (and I'm sure someon

I once wrote a JPEG 'recompressor' that could throw away some of the DCT coefficients, so you could dynamically adjust the size of images when streaming them to a web browser with limited bandwidth - just like the slider in this d

How on earth does cryptocurrency help? If I owned RUB, they've devalued by the same amount vs every other currency, including bitcoin. If your argument is 'you should have bought bitcoin before', then I could have bought any

Doesn't it take hours of wrong password entries before a wipe? The delay between attempts gets longer and longer (at least on ios), you can't just quickly tap in loads of wrong passwords and wipe an iphone in a minute.

Fewer middlemen? Now to buy from your dealer, you have to go via a marketplace, after converting your real money on an exchange. That's at least two other intermediaries...

It's depressing when some maintainers launch a new version of their program, then immediately mass-close huge swathes of bugs with a "if it's still a problem, re-open a new ticket" kind of message. I mean, I get why th

The Open Group's study into LP64/ILP64 explains their choice fairly well. In particular, it mentions both Digital and SGI's prior experience with porting code to LP64. There's nothing about SCO's preferences in it.

The key word is ‘eventually’. How long? Seconds, or even minutes? If your machine locks up, you turn it off and on again. If the drive didn’t bother to flush its internal caches by then, that data is lost, just as in a power failure.

That's a terrible analogy. Are you saying that once a visitor completes a captcha on your website, they can steal all your stuff? In that case, the problem is with you and your website security.

I've not heard of the BPA, how am I to know whether this is a real organisation, or just one that the scammers have made up, with a quick official-looking website? Do you really check wikipedia for every website? Maybe the real group i

No, the problem is the QR code, not the URL. More specifically, it's the context in which you see the QR code. For instance, one scam is replacing the QR codes on parking meters with another one, linking to a different payment site -

Yes. The 'fully Kelly' betting is the fastest growth, but the variance is sky-high in practice. If I remember the math right, while betting using full Kelly stakes, you will have a 50% chance of losing half of your current bank at

I wonder what the minimum % a heuristic could be said to have? When does a heuristic become just an educated guess?

by joosters 5y ago
A pedantic criticism of the title: ‘ Heuristics that almost always work ’ is a truism, or a tautology. If a heuristic worked 100% of the time, it would no longer be a heuristic, it would be a rule!

TCP/IP and DNS were both developed in the early 70s (1972 I think). That is more than 40 years before the first internet company went public. Is that really your belief about how to define when a technology became useful ?
