A New Component

The ArcRod from yesterday defines the center and one end of a longer rod in 'real life'. I propose what would be called a hack if we did something like it in code. I stumble, but recover. Small steps FTW.

We Tried Baseball and It Didn't Work

An allegory? Sarcasm? Humorous pastiche? You decide.

Back to It

(Nov 13, 2025)

Past time to get back to the linkage. I'm glad I'm not on a deadline—other than the big one—and I don't know when that is. Anyway, let's add a link or two. Result: WOOT!

Hear Me Out ...

(Nov 10, 2025)

Let's take back the notion and slogan. Let's describe, all of us, what it would really take to Make America Great Again.

Possible Progress

(Nov 3, 2025)

Studying the Walschaerts linkage, I think I see a path that my scheme can support. So let's see if we can inch into it.

Design Thinking

(Oct 30, 2025)

Upcoming Components challenge us. XP has design thinking. Names are dropped. Brief descent to politics. Cute Video.

Looking Around

(Oct 28, 2025)

Bell Crank is kind of an inflection point. Let's see what we should do next.

Bell Crank

(Oct 27, 2025)

Time for a new component, the bell crank. Not your regular crank, no, but a bell crank.

Tables?

(Oct 24, 2025)

Maybe tables would be a useful way to express a linkage.

\[ python, refactoring, tdd \]

More Better

(Oct 24, 2025)

I've come up with a better way. At least I think it is. Herewith, a report. Green shoes.

\[ python, refactoring, tdd \]

DSL?

(Oct 22, 2025)

We need an easier way to define a Linkage.

\[ python, refactoring, tdd \]

ArcRod Works

(Oct 21, 2025)

Give me an "AI" that cleans the bathroom and leave me to my art.

\[ python, refactoring, tdd \]

Crash and Burn

(Oct 20, 2025)

Log for the Record. Crash and burn. Read only if you want to see me confused.

\[ python, refactoring, tdd \]

Which Way to Go?

(Oct 20, 2025)

There are two possible solutions for the ArcRod's position. We need to specify which one we want. Result promising but I'm sent back to the drawing board.

\[ python, refactoring, tdd \]

Seeing Is Believing

(Oct 19, 2025)

Tests notwithstanding, there's both satisfaction and discovery in animating the linkage. So let's do. (It works!!)

\[ python, refactoring, tdd \]

Bell Crank Target

(Oct 18, 2025)

As much as I'd like to futz with the drawing code, I think it's time to continue work on the ArcRod. I'm goin' in!

I'm Not ALWAYS Right ...

(Oct 17, 2025)

Why, only yesterday, I thought I had made a mistake. Turns out I was wrong, I hadn't made a mistake after all!

\[ python, refactoring, tdd \]

Back to Linkage

(Oct 16, 2025)

Starting late today, might end early. Let's see if there are right-sized things to do. Good thinking, but the work does not go as I anticipated.

\[ python, refactoring, tdd \]

Questions about "AI"

(Oct 15, 2025)

Some rambling thoughts on "AI" and LLMs. Things I think about.

Method Object

(Oct 14, 2025)

Today we do a very nice step by step refactoring to a Method Object. Quite pleasing, really. Yummy.

\[ python, refactoring, tdd \]

Expression

(Oct 13, 2025)

Long ago, Kent Beck described 'simple code' with four rules. One of them was about expressing ideas in code.
