Even if they do, acquiring both of these hashes vastly helps with brute-forcing: you first break the phone key password and then check only the alphanumeric passwords that match it against the alphanumeric password's hash.

There may be a selection bias too: people who were banned just before payout may be more likely to respond to the poll.

I'm not sure about strength being mostly compressive -- for example, Apollo 9's Saturn V withstood a longitudinal oscillation with an amplitude of 12g[1] and it wasn't deemed to be dangerous enough to cause an abort. I'd

If you have two perpendicular polarizers, no light will pass through both. But, if you insert a polarizer at a 45 degree angle to both of them inbetween, some light will pass through. Am I wrong?

Does it also apply to solid state switches actuated by a capacitative touch sensor? I wonder why this or something of a similar nature isn't a solution to most of these issues.

Random Hall (a dorm at MIT) has/had a `bathroom server' that did exactly that and also a `laundry server' that tells you whether the laundry machines are busy. The bathroom server used to be at http://bathroom.mit.

In order to transfer power using magnetic induction you need a _variable in time_ magnetic field, which causes a variable in time electric field to appear. That seems to me to be exactly the description of an electromagnetic wave.

I assume you refer to all the seemingly nitty problems with the pipeline above (from what I can see, there is no way to verify that the archive wasn't tampered with). Would you say the same about a solution that signs and encrypts the

I don't understand why the pingers are on continuously until battery depletion. Assuming we can't have them be triggered by incoming sound (making them essentially sonar transponders), why couldn't they be on for e.g. 15 days

When an aircraft decompresses, the total pressure drops, so pressure sensors are just as useful as oxygen partial pressure sensors. There are pressure sensors in the cabin -- they are used to control the pressurization system, sound low pre

I don't see how these compare: prosecuting murderers is supposed to prevent them from murdering again and, more importantly, discourage other people from murder. What is the parallel effect of proper burial of war casualties?

I'd imagine that they knew the exact timing of the failure from the telemetry from the plane.

If you need to modify the tests together in a parallel fashion to the modifications you make in the code you are more likely to introduce same conceptual bugs in both places.

I would expect memory corruption bugs to be harder to exploit, because their exploiting might require knowledge of some particulars of the environment (maybe we need to know the exact version of the buggy library used, so that we know the m

This is a very old (and nice) problem in streaming algorithms. The solution currently used in most places is HyperLogLog[1], which basically uses the distribution of log(minimum value of hash) for a set of hashes. [1] http://algo

Unless you move the stack pointer by more than a page (the stack in Linux grows automatically: IIRC any access to at most 64k below the stack pointer is considered to be an attempt to grow the stack, because the compiler may very well reord

Would it be considerably expensive to check in runtime that SP is in an expected range every time it gets moved? This'd work with multiple stacks, too.

Or you can do what CyanogenMod does: allow the user to pretend to give some permission to a program. This will obviously devolve into an arms race between better emulation of these permissions and better detection of the emulation (debugger

I've expected the JS interpreter to optimize that out. Turns out I was wrong and the version from the article is even 40% slower for a loop that iterates over 5000 elements and does a trivial amount of work: http://jsperf.co

Can you elaborate on what's wrong with the final solution from the article? I don't see anything wrong there and I wouldn't expect your snippet to be faster.
