Jeremiah Flaga My thoughts and experiences on programming, life, atbp.

Can a scientist be close-minded?



Disclaimer first: I’m not a scientist. I only learned a bit about how things work in the world of science (what laws or theories are, for example) through Dr. Werner Gitt’s talk titled “In the Beginning was Information”

But I read someone in the past who said that when we, normal (non-scientist) people, hear the word scientist, what we have in mind is someone wearing a lab gown, experimenting with things in a neutral fashion and presenting the results, in an unbiased way, of those experiments when they are done.

Then the author went on to say that that is not always the case.

"People naturally resists change"


A few weeks ago, as part of my preparation of my talk on Clean Architecture and TDD, I re-read Uncle Bob’s blog posts on Clean Architecture…

“… I’ve been surprised by the reactions to these ideas. I understand that people naturally resist change; and that lots of programmers aren’t used to the ideas of decoupling (read that clause several times and weep). But this is not some new idea that occurred to me out of the blue. These ideas are old…”

Woody Zuill on "Mob Programming"


When I first heard about “pair programming” a few years ago, I fell in love with it. :heart_eyes:

I thought to myself that this will be a great way to learn from someone else; much better than code review!

I can see firsthand how a master does his work, and I can have someone to guide me with my work! Wow! It is a good way of doing the “transfer of knowledge” thing (which I first heard from my first boss).

It is a great help in minimizing the mistakes that I might put into a codebase, because someone else is looking at my work in real time, which of course will make me confident about my work.

I hoped that someday I will be able to experience doing pair programming.

Grumbling Programmer


Sometimes (or many times?), I am one of those grumbling programmers. (Read this blog post of mine a few months ago)…

I never thought that grumbling or murmuring was very bad until about two weeks ago; when my brother in law, Orland Pervandos, talked about grumbling as one of the “common temptations” that the Corinthians (I Cor 10:10) were experiencing; and that grumbling and complaining are the first two “ungodly deeds” listed in Jude 16.

Clean Architecture and TDD Demo


Like what I said in a previous blog post, I would like to compensate for the failure of not being able to finish my demo during the talk last Saturday. So I have created videos of me performing the demo.

Here are the videos…

In these videos, you will see me making mistakes; you will hear me mispronouncing words :smile:; you will see me breaking the rule of writing the tests first. :laughing:

If you have comments, suggestions, or feedback (negative or positive) about these videos (and about the talk last Saturday, if you were there during the talk :smile:), please tell me.

Architecture is the art of drawing lines -- Uncle Bob Martin


“Architecture is the art of drawing lines”

— Robert Martin

I heard that from Uncle Bob’s “Architecture: The Lost Years (Ruby Midwest 2011)” talk.

This is the diagram that he uses in his talk:


Lots of lines!

Do you see those two black lines in there?
