... so I frankly doubt literal veracity of the headliine.

But I won't dispute that Java has changed the face of programming when comparing worlds before it existed and after, although many languages can make that claim, including C, and probably C++. I'd not be surprised if even BASIC could not be said to have had such a dramatic influence on programming. Fortran and COBOL would be up there as well, possibly even greater than most of the others combined.

It can... although usually I dock all my editor windows to one pane, and use tabs.... but the IDE I use allows me to add any number of panes.

It's interesting that many of the things you've mentioned are ideal for you actually are preferences of mine as well, and in fact, why I use the IDE that I do. It's written in Java, but it performs adequately on my hardware, which for me is all that really matters.

While I have coded without an IDE in the past, and I still do it occasionally for one-off throwaway programs, when it comes to larger projects, I do find that having an IDE dramatically boosts my productivity. All of the things I do with an IDE could theoretically also be done with vi and an appropriate suite of tools, but for myself, the point of using an IDE is to really just have it all bundled in as one, and not have to switch to a different window just to show a call graph or function definition for what is at the current cursor, for example, when a simple hover-window can do the same thing, and since the window disappears as soon as I start typing or otherwise navigating, I don't even need to switch windows again when I resume editing.

TIR in a fiber requires the core to have a higher index of refraction than the cladding. If the core is hollow and surrounded by glass, light that is not traveling exactly parallel to the core edge will escape the core. When the propagation speed of light is lowere in the core, at sufficiently obtuse angles, the light that would otherwise escape the core simply bounces off the core's edges, enabling it to go for long distances even if the fiber is not perfectly straight

Where in my comment did I suggest that solid fibers would communicate faster? I said being solid is necessary for it to function, but I did not say it was faster. The engadget article that was linked to by the comment is extremely sparse on the physics involved, so I am most perplexed about how the cable manages to keep light from escaping... TIR is not possible with a hollow core, so they have to be exploiting some other phenomenon with which I am unfamiliar to achieve the result of guiding the signal through the fiber. That said, I would be surprised if there were not some pretty narrow limits on the types of communication possible (maybe in the form of acceptable frequencies) and probably the distances that high fidelity communication is possible, particularly on a cable that has many twists and turns.

Microsoft Study Finds Technology Hurting Attention Spans 109

While people could focus on a task for 12 seconds back in 2000, that figure dropped to 8 seconds in 2013 (about one second less than a goldfish). Reportedly, a lot of that reduction stems from a combination of smartphones and an avalanche of content. The study found also a sunny side: while presence of technology is hurting attention spans overall, it also appears to improve person's abilities to both multitask and concentrate in short bursts.

One good suit is worth a thousand resumes.
