Rex:
you have hit the nail on its head. Thank you for your text.
I will add a few things to my presentation to answer some of
your questions. I actually used to think and sometimes also
write the same as you did, until I realised that criticism
is futile. One has rather to act constructively, within
one's limitations to change the things.
I do agree that some of the BB demonstrations seem interesting,
but pretty abstract. This, I think, is an embodiment of ETH
teaching tradition of distilling things down to their essence.
Such distilled examples are both useful and impressive. (How about
an MS Windows replacement in 12k lines? It has been done.) However,
in a real world situation one has to implement certain concessions,
like for example providing good examples or writing a manual.
This has been missing, because ETH graduates tended not to have
practical experience in, for example, planetary science.
They found it difficult to talk to guys like me or you,
so they hang up on trying.
In order not to inflate this e-mail, please download my new
release of Gr and Persistent Object Manager from my web page
http://www.pas.rochester.edu/~skulski/Downloads.html
Install by simply unpacking the zip archives (POM and Gr) into
your BB directory. Restart BlackBox. Find menu item Pom. Start
the Cosmic Ray demo. Read documentation before trying it out.
Cosmic rays are close enough to planetary science, I think,
so we will be speaking a common language. Then try to run the demo.
(You need to "toggle the protection" Pom->Toggle Protection.)
Be sure to check the box "xyPlot" before running the demo.
Then try to run the Fourier Transform demo. Before running the demo
press the button "Documentation" (located above the left "tree window").
Here again the documentation should speak in a language familiar
to your background, rather than in ETH-lease.
As a last item, start the Pom->Data Logger. Again begin by reading
the documentation. (The button is located at the bottom of the Data
Logger panel.)
After doing all this, please read my code. I have written lots
and lots of comments for a planetary scientist. Please look at
the code and the comments.
Concerning writing and reading files: please study my Gr. It is not
as well documented as POM is. But it shows how to write and read
texts and files. ("GrDaqDemo -> Read histo from disk demo").
The GrArrays use binary reading and writing, and they even
implement on-the-fly compression.
I wrote Gr out of despair similar to yours. It paid for itself.
I do not anyone but myself who used it, but I did use it since
2001 to perform experiments, display and store data, and I even
wrote several grant proposals where I embedded Gr plots directly
into a BB text. (I used BB editor rather than Word to write
and submit proposals to the US Govt.)
In order to re-evaluate your posting: neither Gr nor POM Data Logger
are demos. Both packages will be used during a million-dollar experiment
that we are now setting up in this lab. Both are real-world reality
applications. Neither one is as clean or as abstract as N.Wirth code
would have been. I do not think I would pass as his student.
But these are real world applications.
Please try out Gr and POM, play with the POM demos, read the Gr manual
("GrPlotter->Interactive User Guide") and please evaluate these
packages from your point of view. Is this what you need? After
you are done evaluating please get back to me and we can start from there.
Hope this helps,
W
PS: Robert Campbell library implements ove 5,000 items like complex
numbers, vectors, arrays, matrices, special functions, and graphics.
If you have not evaluated it yet then you are missing your killer
toolbox package. Robert's libraries alone will justify all the pain
you are now experiencing. Just read his documentation.
