lubuntu toolkit (?)

[Aere Greenway]

Farinet:

Although there are dependencies (such as involving handling of the 
screen) that consume resources as long as the thing they support (the 
screen, for example) is being used, there are dependencies that consume 
no memory or processor-power if you don't use them.

They do, however, use up hard disk space (even when they're not being 
used), though hard disk space is not as severe a limitation as 
processor-usage, or memory.

For example, my application makes use of the Java Runtime Environment 
(JRE), which includes dynamic libraries.

But if you don't run my application (or something else that uses Java), 
the library is not used or loaded into memory.

If you do run my application, the JRE is loaded into memory, and is used 
by my application (and also by any other application that needs it).  
Much of the basic functionality of the Java language is in the JRE 
library, so Java programs tend to be fairly small, because they make use 
of that library.

The down-side is (I think) that once the library is loaded, it remains 
in memory in case another application needs it.  It is removed from 
memory for sure the next time you reboot, and possibly if you log-out, 
and log back in.

I think the QT libraries work in a similar fashion, as well as KDE 
libraries for the applications that need them.

What I'm saying, is that a lot of dependencies don't use up memory or 
processor-power unless you use something that needs them, in which case, 
that dependency comes into play, and it is fortunate that it is there, 
but it then does consume resources, and may continue using resources.

I'm just offering this information as another viewpoint regarding 
dependencies.
