That would be the common word for rope. The claim isn't that it's the ordinary word for rope, but rather a more rare word for rope, maybe for a particular type of rope made of camel hair. Others here have posted the Aramaic word

The OT references aren't vague, but due to the idea of the new covenant, they likely apply as much as the OT prohibitions against touching pig leather or touching a menstruating woman. The only treatment of homosexuality in the NT come

Sorry, from the context, you could assume the above is C++. In C89, floating point literals aren't constant expressions, and static initialization order within a compilation unit is only defined for constant expressions. I believe thi

Fair enough. At Goldman, I don't recall our options and equities trading systems simultaneously having outages, so I think we could always shed risk by reducing our options exposure if the auto-hedger was unable to delta-hedge in the

In Goldman's case, Goldman was literally sending out options orders with as ask price of $0. I don't recall if it was the exchange or regulators that decided "If you bought below $x, you knew you were trading against a broke

The power switches were in locked cages inside colos miles from the nearest Knight employee. The sysadmins could probably power off the boxes remotely, but the devs probably didn't have that access. Yes, a "big red button" k

I definitely had a corrupted CD-R backup that would kernel panic OS X, Windows 2000, and Linux, circa 2003. Though, most of my OS X kernel panics were due to a GPU slowly going bad and randomly corrupting memory (both under OS X and Linux,

It dates at least from the 1886 Berne Convention for the Protection of Literary and Artistic Works (Article 12 uses the word "piracy".) I presume the Berne Convention wasn't the first hyperbolic use of "piracy" to

It's really unfortunate that all of the mainstream OSes run userspace in the lower portions of the address space. Setting the most-significant 13 bits (really, setting the second to 12th bits and at least one of the following bits) of

There was hardware (not sure if it was CPU state or state in the memory controller) to zero-out all of the address bits above the 24th, allowing backward compatibility. I forget the shortcut (option-I? option-M?), but if you selected an ex

One of the advantages of two's compliment (particularly relevant in early hardware that really needed to minimize gate count) is that you can use an adder to perform subtraction: just flip all of the bits of the argument to subtract, a

I'm not sure WASM is markedly different from PNaCL, other than using SSA-based LLVM bitcode instead of a stack-based bytecode.
