In many cases, they can. This what kept poison gas from being used in WW2 - both sides had it (or could easily make it), but chose not to as it would break the "gentlemans agreement" which is the law of war, and encourage the other side to do the same.

Comment Open source language (Score 2) 246

> the critical question for a programming language is less whether it is itself open source and more whether it's feasible to make open source software with it.

I have to disagree - a language which only has one single implementation which is closed source means that the developers using it is locked in and completely at the mercy of the owners of this implementation. Just like with VB6.

I would never consider a closed language for anything else than small, short-lifetime hacks which I do not intend to maintain.

Considering its real purpose is to carry multi-megaton nuclear warheads into Pakistan, recovery is really not high on the priority list.

Yes, that occurred to me too - the stuff they are testing sounds closer to the US hypersonic flight stuff than a "space shuttle":

The mission, which will attract global interest, will evaluate technologies such as hypersonic flight, autonomous landing, powered cruise flight and hypersonic flight using air-breathing propulsion.

> Instead I think the role of the truck driver will change, with less emphasis on managing the controls and more on the strategies involved.

Sure. That job can be done from behind a desk tough, managing not just one single truck but dozens of them, at the same time. With the added benefit of being home for dinner (or breakfast, if you get the night shift).

Trucks have the advantage to planes, that in case of a malfunction, it is much easier to pull over and stop. A service car could then be dispatched, i.e. a technician who comes out and fixes the problem, or a tow / replacement tractor if it can't be fixed.

But overall, much fewer people are needed.

Checkin, on a train? If it is like any long-distance train I've ever taken, you buy the ticket on-line or at the station, then board the train. Once aboard, you stuff your luggage into a rack a few meters from your seat, which is usually pretty big and comfy, at least compared to air travel. Time spent at station is more like 15 minutes, including buffer time (there is usually another train in 1 hour anyway, so you don't need 2 hours of buffer time).

2-3 hours vs. 5-6 means it is easily doable over a weekend, or for a day of meetings, vs. mostly for longer visits / needing a hotel for a meeting.

That of course depends a lot of how much you actually drive. Personally, I probably use less than that pr. year* - but then I hardly use it during the summer (biking to work is quicker, more comfortable, and more flexible), and diesel fuel is very cheap, especially pr. km. If you need to use it more, or use more/more expensive fuel, then of course the costs rise. Especially if you also have a new and expensive car (depreciation)...

* Uh, no - I forgot to add highway charges. Which just for this weekend (600 km return trip to somewhere in Italy, passing through the Mt. Blanc tunnel) was probably close to 200 euro; fuel was less than 50...
