Perhaps, but the salient characteristic of dice is that the sides are marked. When you talk about dice becoming ordered, there is a very strong implication that you mean the sequence of facing sides, not the packing factor. If we must be p

More accurately, cubes pack more closely when agitated one way than another. The fact that they are dice is irrelevant (they don't become ordered with respect to the facing side). To be honest, this isn't particularly odd, as th

Some of the ideas in the pipeline for high-altitude launch to orbit vehicles and hybrid vehicles employing scramjets may exceed this. Assuming the current arc toward private advance aerospace projects continues, I wouldn't be surprise

Wearable tech is incredibly interesting, but I have to be able to imagine myself actually...well, wearing it. Google glass failed primarily just on that (well, that and the people around you not wanting to be filmed).

Agreed, but failure containment is another of its purposes, at least on contemporary turbofan engines.

That's a fair point --- I'm certainly stretching to try to extend 'configurable' into 'stored programs'. I do still think that the shift to storing instructions in electronic memory (once said memories became a

I think this is conflating the stored program design and the Von Neumann machine. The storage of both programs and memory in the same address space was novel, but other options for storing programs exist (see especially Harvard Architectur

That was my initial guess. It could also have been a contained failure that damaged the cowl, which later separated from aerodynamic stress. But the missing fan (and maybe a compressor stage) does seem to imply a shaft failure. The main

Agreed. When I saw the amount of damage, but little on the wing edge (there may be damage on the underside), I assumed the engine maintained confinement long enough to dissipate a lot of energy. If the cowl was damaged during this, then it

That's always the first thought that occurs to me. Any standard or tool that wants to render mathematical notation has to seamlessly interact with and accurately render AMS LaTeX. Without that, working mathematicians simply won'

I'm not advocating DU as a part of a healthy diet. It's more than 100 times as radioactive as bananas, after all. I am saying that the primary danger from DU is not its radioactivity, but the fact that it's a heavy metal. T

The misconceptions about DU in the media always irritate me. People hear "Uranium" and immediately start talking about radioactivity, but the D in DU should remind them that the whole point of DU is that it's significantly l

GUIs lend themselves very well to an object abstraction. The discrete elements (dialogues, menus, controls, etc) are objects that often inherit behaviour from classes of objects (i.e. A modal dialog is a generic dialog is a form is a ...).

OOP wasn't really yet a thing and GUIs (which I think of as the killer app for OO) were still experimental when I was first learning programming. I started out with Fortran and Pascal on a timeshared mainframe. Probably because of this

Ah. Yes, I suppose. As it is easier to find exploits in service of closing them as well as in using them (security researchers seem to mostly come down on the side that this averages out as more secure). If that's what you meant, I

That's a very dubious claim, as it depends on the largely debunked idea of "security through obscurity." Bruce Schneier: https://www.schneier.com/crypto-gram/archives/2002/0515.html...

I'd leave it out of the title altogether as irrelevant. The fact that Struts is distributed with a particular license is no more important in this case than the fact that the foundation that distributes it is incorporated in Delaware.
296.
by ajarmst 9y ago
I find the title irritating, as it seems to impugn open source software as a category. Why is the licensing model even relevant? A better phrasing would be something like "...flaw in a popular web framework" or "...flaw in Ap

Well, I'm glad someone got the joke. Judging by the downvotes, no one seems to appreciate my sense of humor.
