Stretches< Jottings< Random Arrows>

I have returned from Maui. I miss being under the same roof as my entire family. I am happy to return to my cats and work dogs though. I will most likely write about the trip in detail later on.

I need to finish something. I have too many projects at seventy-five to ninety percent finished. How about this for some computer programming wisdom?

Ninety-ninety rule
From Wikipedia, the free encyclopedia
Jump to: navigation, search

In computer programming and software engineering, the ninety-ninety rule is a humorous aphorism that states, "The first 90% of the code accounts for the first 90% of the development time. The remaining 10% of the code accounts for the other 90% of the development time."

That the total development time sums to 180% is a wry allusion to the notorious tendency of software development projects to significantly overrun their original schedules. It expresses both the rough allocation of time to easy and hard portions of a programming project and the cause of the lateness of many projects (that is, failure to anticipate the hard parts). That is, it takes both more time and more coding than expected to make a project work.
