It is nice that you feel a cool and confidant as wherever you work hasn't been hacked yet.

Security problem is across all sectors Government, Non-Profit, corporate...
Why? Well IT Security is a relatively new problem. As we are hooking many systems together. However organizations are still not thinking in terms of IT Security. And also the Buzzword friendly "Agile/Nimble..." organization has no time for such security problems as Good IT people are Expensive, and this Security Work isn't directly affecting the bottom line.

Comment heat (Score 1) 373

While there may be no mass escaping from this device, it absolutely is consuming energy. Where does that go?

In most of the mundane pursuits we understand, it goes to producing heat. In physics, one fairly valid viewpoint is that heat is motion, in that a "hotter" result has more motion activity going on at the particle level.

One of the reasons that perpetual motion is impossible is that within a closed system, we can't make anything 100% efficient. Typically the lost percentage wanders off in some fairly easily identifiable thermal guise.

The first thing to keep in mind is that not all energy expended does useful work.

But that's not really the problem here. the problem is that motion in space, as we understand it, depends entirely on imparting momentum to something. The only way we have practically been able to do that is to send stuff out one end of a spacecraft, which causes, due to the equal and opposite rule of newtonian physics, the spacecraft to go in the opposite direction.

But it's not really about "where does the energy go." This thing is being sold as "doesn't send stuff out one end of spacecraft" and "imparts momentum." The physics folks are looking at that claim very dubiously, because so far, there's no generally accepted science that could account for such a thing.

If it turns out to be a real effect (and I'm not saying it will), then we're going to have some new science to learn.

Comment science fiction, fantasy, etc (Score 2) 373

...science fiction I read when I was young ... violates laws of physics big-time.

Then you were reading (very likely mislabeled) fantasy. The whole point of science fiction is to embed a story within the context of plausible science. Nothing wrong with fantasy, but it isn't, and never has been, science fiction.

Between the "speculative fiction" rendering down of that specific distinction, and the marketing-driven labeling of fantasy as science fiction, and the tendency of bookstores for decades to lump fantasy and science fiction together, your experience is the rule, rather than the exception.

But there's still science fiction being written. The trick is finding it.

Comment Re:Java? (Score 1) 346

Java is a good choice for bosses who are still stuck on decade old buzzwords and you don't want to use .NET.
Because of that it is a language known by a lot of people and schools teach it as part of the Computer Science Program. So it is easier to find people with that set of skills for larger projects taking a team of developers.

In the 1980's we had COBOL -- Built mainly for mainframes and filling out forms data and parsing fixed sized files (often compatible with magnetic tape)

In the 1990's we moved to C/C++/Visual Basic -- We moved to the slower PC hardware so we needed the Speed of C/C++ and/or the ability to handle he new GUI capabilities that VB offered.

In the 2000's we moved to Java/.NET -- Finding that are gping to be moving from 32bit to 64bit computing also dealing with many rough OS upgrades the bytecode languages offered easier migrations. Here is Java Strongest point, because compared to .NET you could actually make cross compatible products.

In the 2010's we are moving towards JavaScript/Python/Ruby -- As our personal devices are getting smaller at the expense of performance we are moving towards cloud based solutions so we emphasising more on Web Technologies and Server hosted processing.

We need to stop being hypocrites about our values.
Private communication risks our security (As the bad guys cannot be monitored).
Security risks our privacy (As the good guys will be monitored).

I would also like to make a point it doesn't take a team of super geniuses to code an encrypted and unrecorded communication protocol. Just one guy, and less than one day of work. It may not be clean and polished, but it would do the job.
