Ada 2012 Language Approved As Standard By ISO

darkestkhan Re:ISO? We don't trust them any more. (165 comments)

Keywords do have well defined behaviors, so I don't see where "repurposing everything - including the ""="" operator and keywords like ""if""" happened.
And you actually do need to permit overloading of operators (otherwise you end up with nasty code [ie. in complex arithmetic]).

Ada 2012 Language Approved As Standard By ISO

darkestkhan Re:Anybody using Ada? (165 comments)

And you know... those projects that moved from Ada to C/C++ are strangely overtime (many years by now) ONLY because of software BUGS. Seems like they got a lot of problems from that switch.

And IMHO if your programmer can't learn enough Ada to be productive in 2 weeks then they are quite bad programmers.

Innovative Use of Plastics Could Cheaply Double Solar Cell Output

darkestkhan Re:Power companies (141 comments)

would not be very useful for me where i live it is cloudy and rainy or fogy most of the year but the idea has marret . if only tesla and edison had not bee so apposed we would have dc power in our homes and every device would not need its own intagrated converter, but dc is bad for long distant transmission if only we had dc in home and ac betwen source and the power box on the house

No, it is not - in fact DC is even better for long distance transmission than AC ever was http://en.wikipedia.org/wiki/Direct_current http://en.wikipedia.org/wiki/Alternating_current http://en.wikipedia.org/wiki/AC_power http://en.wikipedia.org/wiki/HVDC http://en.wikipedia.org/wiki/War_of_Currents .AC won because in XIX century (and to to the second half of XX century) changing voltage of DC was hard and inefficient (but it is not the case today). But we would still need transformers, and that is easier done with AC than DC.

Voyager 1 Exits Our Solar System

darkestkhan Re:Amazing (341 comments)

I believe Moore's Law (after needed change) can be applied to anything that is actively used and developed - eg. price of space launches per kg halves every ~10 years, amount of qubits doubles ~6 years

Producing products that can last decades but for which time of exponentiation is <5 years doesn't make too much sense - extreme cases are our current CPU's (heck, my brother has P4 3GHz inside his box, and my laptop has T3400 (2 core), from which 1 core has computational capability of his entire P4, while entire CPU (on 100% load) takes 4-5 times less energy than P4) were [total] computational capability is doubling every ~2 years, making it rather meaningless to produce systems that can last decades.
