[sf-lug] Tutor me in Programming?

Sun Sep 7 10:12:20 PDT 2008

   wow! dennis is right: present the entire problem 
so others understand or can re-interpret what's 
going on. 
   it seems to me that sometimes (hopefully often) 
you can encapsulate parts of the program into parts 
(such as classes/objects or functions) so that you 
can present data and ask about activities within 
the object or function. beware that as you develop 
your whole program, you might be going in a less 
than optimum direction, and asking about an isolated 
part of a poorly structured program might get help 
with a small part that lets you continue down a 
wrong path. 

   also, it's a matter of experience (note dennis' 
story). don't beat yourself up: the fact that you 
recognize the aspect is great! it'll take time to 
get better, enjoy the process (again, per dennis' 
advice, although i'd say switch to shoe repair or 
sailing rather than marketing). 

   (there are people who write programs similar to 
emulating bubble-wrap: the essence of these designs 
is generally some mathematical modeling that 
expresses algorithms abstracted from any particular 
programming language.) 

   look up algorithms. the older literature tends 
to concentrate on various data structures and is 
oriented to procedural programming, but that's a 
good starting point.
