Is there some paper (possibly in english) somewhere about a comparison
beetween this technologies?
Actually I’m in the way to substain an exam [1] in the next week
about distributed technologies and I’d like to plug ruby into it.
some hint ?
[1] I’m the student , not the teacher. Usually I have problem
comunicating this in english
I can’t help you with the Ruby, but I will with the English.
There’s no such word as “substain”. As a student, one can
sit an exam
take an exam
and probably others. “sit” is probably the word you’re after.
Cheers,
Gavin

‘attain’ seems to make sense too ?

ok, I’ll appreciate this too

doh!
That’s a thing I usually do when sitting to much in front of the
keyboard. I invent english word by
english_word=my_home_lang_word.chop
strange to say, many times this worked

I suppose people told me this before but I always forget it…
thank you very much for your help.

‘attain’ implies success, doesn’t it? sit or take would be more
appropriate I think.
sadly, my CORBA and RMI skills are very limited. In stead I could
comment on DCOM (the MS approach to distributed computing): DCOM (or
COM+ as it is called these days) has a lot in common with CORBA (or so,
I’ve been told). The basic idea is to have a description of an object,
which the caller of the object uses to find out what methods are
available and which parameters they receive and what type the value
returned from the method has. MS has invented a language they call IDL -
interface description language for this purpose. There is nothing
special about MS IDL. It lets you describe the methods you of your
object mothing more - nothing less. You should be away that there is a
limit to the number of methods a COM+ object can have (127). Each method
must have a unique id (which is 7 bits wide) attached to it. There is no
real reason why this must be so - all methods are called by name, not by
the unique id it receives.
When implementing a COM+ interface all datatypes must be VisualBasic
compatible (guess why), which means that there is quite a bit of data
conversion that must be done whenever method parameters are read or data
is returned from a method. This is a bit of a hassle if you do not want
to use MFC and all that comes with it.
My druby experience is, sadly, also very limited: I have tested it once,
just to see how it works. AFAIK mashalling is used in druby to transmit
data across networks. There is no interface description needed in order
to work on a remote object, no hassles, you work on remote objects the
same way as you would with local objects.
Comparing CORBA and COM+ to druby is a bit unfair, since druby will
never work across languages (neither will RMI, so a comparison there
might be in order). CORBA and COM+ are solving issues with little/big
endian and calling conventions across networks AND programming languages.
Hope this helps

When I read this I thought of the word “sustain”, as in
“sustaining an injury”; depending on how well prepared one is for an
exam, one might say (tounge firmly in cheek), “I sustained an exam
yesterday, but should be fully recovered by the weekend.”
That’s typically how I felt about Chemistry exams back in my
college days …
