Comment Why batteries? Hydrogen much denser. (Score 1) 53

As I posted below, it seems pretty obvious you would use fuel cells instead of batteries for an electric aircraft... from your energy density link compressed hydrogen has an even better energy density (142 MJ/kg) than jet fuel (46 MJ/kg)!

The cost of hydrogen production is estimated to become close to gasoline production over the next decade or so, but there is a huge pollution benefit to using fuel cells which could drive adoption quicker.

The currently very low cost of oil is probably the main thing that would keep airplanes from going electric soon.

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.

And it's not as if Exchange is easy. Yes, there's the brain dead configuration that comes out of the box, but if you want to do anything like advanced filtering it suddenly becomes very complex. We run Exchange 2010 where I work, and a few months ago I wanted to do some scripting on incoming emails to a specific mailbox. Certainly possible, but man oh man, between being forced to work in Powershell and the awkwardness of Exchange itself, I ended up implementing it on the Postfix server that sits between the Exchange server and the network. Postfix passes off the message via STDIO to my Bash script, I pulled out the attachments I need to save elsewhere for further processing, and it's been humming like a charm ever since.

Maybe some of it has to do with the fact that I'm a *nix guy, and it's more familiar terrain, but I really can't get over just difficult Powershell and Exchange can be, where the *nix philosophy just makes things so much easier.

Comment It is code; the clue is in the name. (Score 2) 112

I program by writing in text files too, but that's just important for interoperability with other tools, it's not the definition of coding. Everyone knows that our CPUs don't execute ASCII, right? If it's Turing-complete, then it can be interpreted or compiled (i.e. "decoded") to do anything you want to execute.

Comment Probably not that useful in the end (Score 1) 34

Multiple monitors pretty much give you the same thing. VR is useful when you're working on something you can walk around, but since there's really no such thing as a natural walking controller that truly naturally emulates a space larger than your available playroom, it's not really sensible here. We already have tools for moving around 3d spaces that we're not actually in, and they work pretty well.

A creature modeling tool that lets you work in a VR space is useful. A level modeling tool that does the same is a lot less so.
