Well... to be fair if the energy of insolation were already being totally retained, then increasing the amount of CO2 and methane would have no effect on heating, and one should expect a decrease in effectiveness as one approaches the limiting case. Not that I think they are actually reasoning that way, and not that this would mean the other effects would decrease...

Well, actually since they quote 95% they're being conservative. 100% of the models are KNOWN to be in error. The questions are always "How much in error?" and "In which direction?". And nobody really knows the answers to those questions, though sometimes there are reasonable estimates.

What he's really saying is "I don't like your answers, so you're wrong. And I don't need to prove it." Since he's politically well connected this is actually largely correct. The only error is logically evident (from my phrasing of "what he was really saying").

The washer and dryer primarily spend their energy on heating, not on running the motor. Using less water means savings on electricity because there is less water to heat. Dryers jump dramatically in efficiency when you switch to a condensing dryer, since you save most of the heat that went into turning water into steam.

They did not spend millions of dollars looking for the microwave oven, and they knew all along that the signal was man-made. Figuring out precisely which item made it is the kind of thing that gets you in the newspapers, so they did a little PR stunt.

Their usual work changes our understanding of the universe but does not have a chance to make it into the mainstream news. Can you begrudge them their 15 minutes of fame?

If you're going to consider obsolete languages (the keyboards are no longer made) I'd nominate Prograf. It was a dataflow language that would have been great for multiprocessor systems except for two problems:
1) It was released for the Mac System 3 and never successfully transitioned to later systems, and
2) There was no text representation of the programs, it was all graphic, which was quickly too verbose to handle as the programs increased in size.

Not clear on what you consider "good". The ones that occur to me are WxWidgets, Qt, and Tcl...which can be good depending on your purpose. All of those can be used on Linux, Apple, and MSWind, and probably on BSD. All of them can be used from C, C++, Python, and Ruby. And, I assume, other languages.

If you want a good graphic builder IDE, then Qt has some quite decent tools. I'm not sure about WxWidgets. Tcl used to, but they seem to have died of neglect.

Then there's Java which goes its own way, and has it's own GUI, and IDE with a gui-builder...but while adequate for many purposes, I find the Java gui to be limited even when compared to Tcl. Still, it *is* cross-platform.

So I guess it comes down to "what do you mean by 'good'?".

If I read the article announcing the release correctly, then while the basic C# language is (probably) open source, it's definitely not free. You can't make a version of it without the agreement of MS, and the released version by MS is ... incomplete. Parts of it are portable, others aren't. So you can only use it as MS desires.

IIRC the release agreement said something like "permission is given to any full and complete implementation that fully implements the specifications" I forget whether the specifications were subject to unilateral change by MS, but even if they weren't it means that the language cannot be implemented by anyone except as desired by MS. Also, of course, the libraries were not made available, which reders it essentially useless except on MSWind machines.

Now just because their public promise didn't allow something doesn't mean that they won't ignore any "infringing" code as long as they feel like it. But it does mean that only a trusting (characterization deleted) would put their own time and effort behind it...without some form of idemnification.

So I'm going to pass on C#. It'd rather trust Oracle's Java (which I also avoid, though not all the time).

Different langaguages are different.

OTOH, I disagree with the basic premise of the article. It is my belief that one shouldn't learn a new language to improve ones job prospects, but rather to improve ones skills as a programmer. So if you know C++, then you don't learn C# or Java, but rather Eiffel, Lisp, or Haskell, or possibly OCaML.

OTOH, If you already know C++ or Java, it's certainly easier to learn Python or Ruby. So easy that a basic knowledge can be learned in a day. So if you're tight on time, that will allow you to expand your capabilities in small increments. (But a basic knowledge won't teach you the libraries, which is where the important differences lie.)

FWIW, I first learned Fortan, actually FORTRAN, since it was before Fortran 77 was standardized. But then I went on to Snobol, PL/1, etc. I never did really master LISP1.5, but I didn't have access to a running implementation. With Lisps a decent IDE is nearly a necessity to start with. (Currently, if you want to pick up a lisp, I'd recomment Racket Scheme from PLT. It's got a decent development environment.)

OTOH, I dropped C++ about 20 years ago, and am no longer fluent in the modern dialect (something I keep meaning to correct). My current favorite language is D (Digital Mars D, or dmd), before that I cycled between Ruby and Python. Before I retired I normally wrote in whatever my employer chose, which, towards the end, was MSAccess Basic...a really foul language. So foul I wrote routines in Eiffel that did the work and just used the MSAccess Basic as a driver. Not only was it faster to write, it was also faster to execute, and unlike MSAccessBasic, the programs wouldn't arbitrarily start failing after a few months of use. (In the AccessBasis I used to need to save the programs as text files so that I could re-import them after the system corrupted them. Figuring out that there wasn't actually anything wrong with the programs took a lot of quite furstrating debugging, since a newly entered program would work properly. It's my guess that the system was storing some invisible binary code in with the source, so the source became unusable when the code got corrupted...why the code ever got corrupted I never found out, but it happened repeatedly to many different programs.) I presume that MS has by now fixed the problem, but it persisted over at least 5 years and multiple different versions of MSAccess.

I'm sorry, I don't understand what you mean. I rather despise Obama as a president, but I can't think of any particular scandal...and I mean something *I* consider a scandal, not something that titillates the shocked sensibilities of those who are appalled by a "wardrobe malfunction". The closest I can come is his acceptance of RomenyCare as his health plan (i.e. "ObamaCare"), but while appalling, I can hardly consider that a scandal.
