What is Object Oriented Programming?
I recently gossiped again about how formal education did not properly define topics such as OOP. So here's my attempt:
In OOP, you can define your own data types, called classes. A class can consist of some data structures and some code associated with the class. A variable whose type is a class is called an object. Thus objects logically tie some data to some code. Classes can contain objects of another class (has a), or classes can inherit from other classes (is a).
Two aphorisms on the work
Today we had a course on the matter of quality. I contributed two paraphrased sayings during this. This is the first one:
The master has failed more times than the beginner has even tried.
Stephen McCranie
Copied for the blog from https://www.goodreads.com/quotes/1252243-the-master-has-failed-more-times-than-the-beginner-has
The second appears to be less specifically cited to one source in particular. It goes like this: Good, Fast, Cheap. Pick two.
Searching the web for this turns up the Wikipedia article on the "Project management triangle" which lists scope, cost, and time as the corners. The middle of this triangle is labeled as quality. Here's another article about it, referring to the three points with my terms.
Mid April work

This week I did some work on ldosboot, the checksumming companion repo, and lDebug.
Early April work

On the prior weekend, which saw the (protestant) Easter celebrations, the HP 95LX's battery unfortunately had run out of power. That is why I didn't prepare a blog post at the usual time.
TSR updates, kernel boot test, more V20 bug tests
2023-04-02
This last week, I worked some on the updates to the TSR example, slightly extended the inst2d2f tool and set it up for current builds, did a few minor updates to lDebug, and I finally merged the ecm-boot-test branch for the FreeDOS kernel. I also checked whether the long-form pop on the 95LX can be traced or proceeded past without a crash, testing all 7 GPRs other than sp.
