MS one step closer to the grave or open source

Damn FAST!!!!

Parallel computing isn’t of much use to most ordinary folks.

Scene rendering uses parallel computing. You think the average person might like being able to create nice-looking animation? You think video game designers might like that capability?

[ThomasMore]

Holographic Computing.

[Bullish]

Does this basically mean a virtually unlimited amount of RAM to run programs fast as lightning?

Na, I use Ada's TASK construct, which has been included in the language since it's inception in 1983... which means that it foresaw this situation (parallel computation) more than thirty years ago. Indeed, they've been adding features to the tasking-model to ease some multi-core issues (core preference, and such).

Very interesting for 3D graphics rendering and other engineering considerations.

No, but you can probably debunk it with this rig.

Fun.

[Errant]

Among the many benefits: a couple of orders of magnitude in increased processing ability for the same amount of energy, at greatly reduced costs in hardware.

ADA? how quaint~!

(just kidding)

[OneWingedShark]

ADA?

No, Ada. It's a proper name, nor an acronym (I'd hate to program in the Americans with Disabilities Act) -- Ironically the one time that casing is important (well, besides string internals).

how quaint~!

quaint     [kweynt]
adjective

1. having an old-fashioned attractiveness or charm; oddly picturesque: a quaint old house.
2. strange, peculiar, or unusual in an interesting, pleasing, or amusing way: a quaint sense of humor.
3. skillfully or cleverly made.
4. Obsolete. wise; skilled.

Hm, which definition do you mean? In the case of:
1. Yes, strong-typing with an aim towards static analysis is very old-fashioned compared to the newfangled web/scripting languages.
2. A language designed with tangible goals like maintainability, large-systems design, and early detection of errors is quite unusual.
3. I agree.
4. Again, I agree.

(just kidding)

Awww.. :(
;)

But seriously, the new 2012 standard is nice: we got some fine tuning of TASK-constructs, contracts (pre- & post-conditions, along w/ type invariants), quantified expressions (for all and for some), conditionals (if X in positive then 128.0 / X else 0.0) [same w/ case, definite plus for having CASE-coverage (since Ada83)], some new containers.

I can get you some links if you're interested.

[Mr. K]

Nah, just call me when they want to reprogram it all in c#

:P

[OneWingedShark]

I don't see that happening for things like Avionics, certainly not things like the Apache helicopter and the F-22.

[Mr. K]

I am actually getting a lot of calls for c# conversions.

Is Ada still used that extensively? Is there a high demand for it (and high$$$)? Maybe I should look into it.

I have been joking with you a bit about this (my language is better than yours Ntah! nyah!) but it is all in good fun.

I love doing avionics and hardware control- most of the embedded systems work I get calls for are in c++

Yeah, it sounds like a great field -- I'd love to get in, but I'm stuck with the "entry-level catch-22" -- you know, the entry-level job "requires X years of experience in the industry"... which you can't get w/o an entry-level job.

I have been joking with you a bit about this (my language is better than yours Ntah! nyah!) but it is all in good fun.

I could tell that.

It seems to be; the life-cycles in aeronautics are LONG compared to elsewhere (the 747 started production in 1968) ~ given that the F-22 is [mostly] done in Ada (I heard there were things like cockpit-control were C++) and the 777 is entirely Ada there's going to be some demand for it. (Again, the only reason I can see I'm not getting the jobs is because companies [in general] want people "pre-packaged" for the position [i.e. no training required].)

I am actually getting a lot of calls for c# conversions.

I've been involved in some C# conversions myself, in user applications, the notable one being a conversion from Access to C#. I cam in on the tail and basically had to fix porting issues (they changed development environs from VS 2008 to 2010 and .NET 2.0 to 3.5 as well as moving the system to other machines) -- I initially got the job of "fix it so it compiles" [reference fix-up]... and then put on maintenance -- the thing is kind of a wreck in that it's more a transliteration than a conversion/translation, and you can tell it was mostly developed by intern sorts who had no experience maintaining a system. (You quickly learn to hate "cut and paste programming".)
