The advice about enabling -ffast-math is dangerous. Be advised that the fpclassify() family of functions (e.g. checking for NaN or infinity) no longer work as expected. If you really want to go into that territory, be sure to read the compi

Please point to a proof of the security of symmetric crypto if you can. Last I checked, such a proof would have still been considered an incredible breakthrough. All that people are doing is to show that k rounds of cypher C can be broken,

This is interesting in that it highlights a number of problems that every peer-to-peer network that wishes to use something like Tor for privacy needs to take into account. I also wasn't aware that Tor hidden services can be "bl

I'm running Firefox on a fairly beefy laptop, and the integrated PDF viewer annoyed me so much that I disabled it some time last year. I suppose it's fine for simple stuff, and it's definitely better than an Adobe Reader plug

It's a matter of pragmatism. When you have a sequence of functions that all return (res, err) pairs, it's extremely helpful to be able to use := even though the err is not redefined. Occasionally, I wonder whether := with several

That's how I interpret it as well, though I don't see how one would implement this. Would we all have to start collecting all our receipts, even for private purchases? That seems like a headache...

One might call passive investment "hoarding" because it does not really encourage economic activity. See, "investment" is such a loaded term. Somebody who uses their savings to open a restaurant is clearly making an &quo

I think you're right. Just FYI, the line of thought of Gates here is probably based on the idea that you need "capital" in order to have a productive work force. If the rich spend all their money for consumption, then there

Correct. Furthermore, if no other bank is willing to lend this amount, then the central bank will do so as part of its purpose as lender of last resort (so the condition in your "so long as" is always satisfied). Note, however, th

No. This is probably the most widely spread misunderstanding about banking. A reserve requirement says the following: Sum up the amount of deposits of a bank (on the passive, debt side of the balance sheet), call that A. Then look at what t
