It might be possible that you're suffering from an operating system driver problem, e.g. from your graphics driver. It's worth checking if there is a graphics driver update available for your system.

It's persisted through multiple driver updates and indeed multiple graphics cards. It's probably related to some plugin, but why should a plugin even know that the system has been suspended?

Also, there's a lot of diversity in terms of aircraft electrification that one can take, it's not an all-or-nothing thing. There's lots of different proposals for varying degrees - for example, high bypass with electric turbofans, using onboard electricity to spin the compressor so that you don't have to have a turbine, and so forth.

Yes. Also, you can't ignore comparative efficiencies of engines. Or engine mass to weight ratios. Or the length of time to market, and the expected level of battery change during that time period. Or side benefits (for example, the ability to have small, very light engines was made use of in one NASA experiment that placed numerous small engines along a wing, causing an effect that created drastically more lift at low speeds and allowing for a much shorter takeoff distance).

And beyond that, you can't ignore economics. Having reduced range but getting your fuel at a fraction of a cost may ultimately prove to be more desirable. It's a very complex issue that one can't just make all-encompassing statements based on a single figure like "energy density of batteries vs. energy density of fuel".

Anyway, this is hardly Elon's first time to mention it. Years ago he mentioned that he wants to be the first person to have an electric plane break the sound barrier. If there's anything one can say about Elon, it's that he sure doesn't set the bar low...

No, it does not form "one huge crystal". Nitrogen ices at these temperatures have little structural integrity. It was well known before we got to Pluto that if we saw any sort of relevant topography, we'd know immediately that it was from water ice, as nitrogen ices are so weak that they'd just flow slack over time.

The biggest hurdle they have to cross with solving those problems right now is: addons. Yes, that's right, addons are keeping us from having the performance/multi-process upgrades we so desire in Firefox, because so many of them were written to depend on a slow and single-process Firefox.

Nonsense. You just announce that a new version is coming that will not support the old addons, and start releasing alphas a year (or so) before actually abandoning the old browser for the new one so that people have time to port the popular plugins.

I use MS products every bloody day. We upgraded to a Server 2012 network last year, we run Exchange 2010, all our workstations run Windows, with Office on them.

I have to deal with its often inelegant solutions to automation and remote administration (seriously, at one point we had GUI "scripting"). Yes, they've built better tools than they had, but all those tools ever seem to do is demonstrate the old maxim; those that don't understand Unix are doomed to re-implement it badly. Even Powershell is just gawdawful hard to use, and while it's better than the collection vbscript files, batch files, registry files and the like that came before it, I still find the process of Windows scripting just dreadful.

Windows needs Bash and the standard Unix toolkit, badly. Yes, there might be some kludges here and there, but WTF is the registry but just a bunch of setting/value pairs in a hierarchy. We were using text-based tools ten years ago to manipulate it, building registry files or using CLI registry utilities. Binary data was a pain, to be sure, but most of the registry is all just plain text.
