Are there limits to object-orientation in a system?
This is a query I have had for some time but, have been able to
articulate it accurately only now:
Are there not certain limits to Object Orientation certain types of
systems that are commonly developed, like a Web enabled application
that interacts with a database.
When interacting with a database, we often call stored procedures from
some manager class.
This mechanism is inherently non object oriented as the interface that
the database provides is organized into procedures and not objects.
The problem with this approach is that there is a difficulty in
encapsulating const...What is your favorite object-oriented system library for Scheme?
What is your favorite object-oriented system library for Scheme?
Although I don't think that OO is the most common way folks solve
using Scheme, it is quite possible.
Do most of you that use Scheme use objects when you want them, or does
make more sense to use Common Lisp if you are doing objects?
To all Mac addicts, Newton fans, NEXTStep gurus, Zaurus-advocats:
myPDA is a MacOS X like GUI for the Zaurus. It replaces QPE without
deleting it from memory or requiring to flash the ROM.
* Zaurus 5500G (other Zaurii may work)
* with ROM 2.38 (I have neither tested with OPIE nor ROM 3.10)
Installation of myPDA
1. download the .ipk from
2. Simply copy the .ipks of myPDA and mySTEP to your Zaurus
3. Install both packages to RAM! ...~/Library/ vs ~/System/Library vs /User/Library/
And there is a fourth one in ~/var/root/. I would like to understand in
which case does a system access or write to a certain Library?
Logical assumption would be that it depends on the current user, but
for instance some of the preferences or support files are written to a
~/Library regardless of which user is currently logged in.
I also noticed that if I register an app logged in as an user, I have a
problem running it as a root. This doesn't seem to be a permission
issue, rather a support files access problem. But then it sort of
"goes away" and I can't establish any ...Difference /Library and /System/Library

A200 has a limit or 32,000+ objects.
What is the definition of an 'object'?
Does it include controls on a form etc as they are referred to as objects as
well in documentation?
What does the table MSysQueries count as it has 22,000 records but I don't
have that many queries?
Sorry for multiple questions but just trying to work out how close to limits
a db is and can't find any clear explanation.
MSysQueries contains many records for each query. For instance, it has a
record to define each field or calculated column in a query that is being
displayed in the results...IBM Personal System/2
I have a box labeled: IBM Personal System/2 - System Library and there
are tons of little books inside containing detailed documentation
regarding PS/2 computer systems and OS/2 2.0. They are in incredibly
good shape. Covers still shiny as ever. Anyone know how much I could
make selling these?

The difference is that you shouldn't put anything under /System unless
you know you should. And even then double-check. That's Apple's sandbox...Forms Object Groups vs Object Libraries
I have been reading up on Oracle Forms object groups and object libraries.
Can you tell me the pros and cons of one over the other?
From what I know, the object groups are nice if I wanted to have different
groups for each type of application, but I like the feature where you can
use smart classes if object libraries are used. I guess I am really wanting
to know if smart classes can be used on the objects inside object groups
that live in object libraries.
