Random Thoughts ...on... Pre-mature Optimization

OK, not really random thoughts as I've been thinking about this for quite some time.  Sometimes it take a lot of reflection to understand what reality is (at least as I've perceived it).

There are a number of sayings that are too simplistic on review.  Hey, there are a lot of sayings that sound good in the moment but other than a quick emotional appeal, do not help with the needs at hand.  They are the quick 2 min fix that does not fix anything and still leave you as directionless as before.

So there is my software saying : "Don't pre-optimize your code".

At first glance this sounds correct and certainly applies for architectural issues and design, that may change to reflect implementation issues.

But at a personal level, does this really apply?

I mostly view the world through my own eyes and from my perspective, my toolkit, knowledge and experience is rather deep so that any code that I write is already efficient to a large extent.  So much so that I rarely need to go back and re-write my code for optimization.  For any given feature, I've already analyzed the implementation options in my mind and already pruned out the inefficient paths and settles on a clean design and patterns well before I start coding.

Looking back in time, I remember when junior coders have tried and failed to implement efficient implements that required re-work and sometimes a complete re-implementation.  It's not that their code did not work, it did, but there where bugs that could not be rectified with the current implementation.  Digging deeper I wanted to understand why this was the case.

Most features and coding is rather simplistic (web pages and forms come to mind) so that almost anybody that has a good understanding of the language (aka, JavaScript), will result in an acceptable implementation.  The problem arise when the solution set lays outside of the coders experience set.

In these cases the coder should not pre-optimize because they don't have that knowledge yet.  Veteran coders will write optimized code as they code, but the more junior coder will not know how for a more complex solution.

A solution set that represent this are "state" systems and "mutli-threading" (aka, WebSockets for web pages), where there are added dimensions to account for.   Coders that have NOT been exposed to the designs and patterns for handling these cases will try to overcome them by adding flags, extra timeouts and other simple tricks to get the operational behavior that is required.  All the while they are just hiding the issues without ever solving it.  The resulting implementation could be so flawed that a re-write is required.

At this point, the coder would need to take a large leap on the learning curve to reach this higher level of knowledge.  The real issue is they may not know this unless someone is around to guild them through this and there maybe additional pressure from management to "get it working".

There is kind of an unwritten myth that one you learn how to code, you can code anything.   It's true if you know where your knowledge ends and when you need to stop and gain deeper understanding.

This is the opposite of the Imposter Syndrome where you feel not up to a task.  This problem is where you are too optimistic about your skills and end up digging a deep hole that you can't escape from.

This leads in the Full-Stack vs Specialist programmer issue.  But this is for a later article.  For now just keep learning.

There is no "Right" way.

It's not that your way is not the right way, it's that everyone has their own right way.  So which is the right way?  Is there a right way? Software development is full of discussions that revolve about the "right" way of doing something. The terms used in discussing software design, tools and implementation are so undefined as to make them meaningless.  Code is not designed and written in a vacuum, it's designed by real people in real companies, each with their own constraints and issues.  Code that may look like a hack could have been the result of an employee dragged out of bed at 2am by a company shirt that only cared that they they did not lose their personal client the next morning.  Everything must be looked at in context.  A project written to "Best Practices" may never be finished before development funding dries up.   Goals, vision, constraints and thoughts should be somewhat aligned for project to be successful (or at least enjoyable ...

3rd Try is a Charm

I've been trying to draw / paint these barns for a couple of years but never felt or got them right.  This time I think they turned out right. So What went wrong before and what's right now with this drawing?  This time, the light was right.  It's coming from the upper right and the shadows just looked right.  The other thing is the corn field on the left had to "be in season", otherwise it's just a plowed field.  I had taken other photos from different angles but they never felt right.  This angle has the road, power lines, corn field, etc. all leading to the right.  The shadows on the lower right helps fill in that corner (don't forget about the corners!).  The last part is trying to draw (ink paint maybe) the trees in the background.  Not so easy when they are kind of a blob is green shades. So yeah, it's composition that is king.  Many times I just don't see it until the drawing / painting is finished and when it's right it feels goo...

So THIS is My Style?

 If I play around long enough my style will appear.  I'm guessing that this is kind of it.  I'll keep working on other techniques in watercolor but for now this appears to be my style. I do like it and others appear (to my face) to also like this.  Not every one of my paintings is a success.  About 1/3 so far, but when they do I am rather pleased that anything good comes out of it at all. I do love color.  Color is happy and outdoors is full of color, be it the west or back east with the greens.  Color color color. Also doing some painting on hot press paper and see how that goes.
