The Principle of Priority

Category:

While browsing through my notes on The War of Art of Steven Pressfield, I found this:

I’m keenly aware of the Principle of Priority, which states (a) you must know the difference between what is urgent and what is important, and (b) you must do what’s important first.

I heard a similar statement from Uncle Bob in chapter two of Clean Architecture: A Craftsman’s Guide to Software Structure and Design.

Proactive

Category:

The last time I remember hearing that word is when it was used by our most senior software developer in my second job.

He said that he wants us to be proactive, and not just reactive.

What does that mean?

[google…]

Am I really a Christian?... just an undisciplined one?

Category:

What does it take to be a Christian?

I was taught that if there is at least one point in your life where you believed in Jesus Christ as your saviour then you are a Christian.

But I was also taught that there are real conversions and false conversions.

Hmmm…

Then… I saw some facebook posts that say something like, “to be a Christian, you must believe and continue to believe”, or something like that; “you must repent and continue to repent”… (and the Shocking Youth Message of Paul Washer also!)

A better way than OO!... and TDD?

Category:

I get it already...

Category:

Each software development team is different from the other. What works in one team might not work in another.

Each team must agree to some set of values when working on a project.

A team must make a new participant agree to their set of values.

A new member of a team must agree with the team’s existing set of values.

I’m a TDD fan. But many others are not.

Rethinking the use of TDD

Category:

This is what Jimmy Bogard said in the conclusion of his talk, “Crafting Wicked Domain Models” (NDC 2012):

DDD is all about building domain models that encapsulate the behavior.

So I’m not hiding behavior. I’m just saying it’s up to the domain model itself to perform all these operations itself, and its gonna take care of its own. It defines its boundaries — it does not let anyone do whatever it wants. It wraps up everyting nicely in a nice neat bowl.

This is how I was able to eliminate bugs in our application a lot more easily than just writing a whole bunch of tests. Writing a bunch of tests still requires me to know how to write those tests, but in this case the domain model is offering me the right path.

That last sentence makes me rethink the use of TDD in creating (almost) bug-free software.

TDD might help in teaching about design, even without a teacher

Category:

In his talk, “The Deep Synergy Between Testability and Good Design (NDC 2010)”, Michael Feathers said these:

“If your code is not testable, then it is not a good design.”

“In general, every time you encounter a testability problem, there is an underlying design problem.”

“If you’re finding trouble testing things, reconsider your design and end up with something better.”

Perhaps writing tests can be used in teaching design when no teacher is available to teach design!?

"They will pardon my english"

Category:

Okay…

I’m going public…

I’m not an English teacher. And English is not my native language.

They will “pardon my english”… I hope… :smile:

Fernando Cejas - Be prepare for change image

What is the most basic rule when writing code?

Do you like simple rules?

Simple rules

I like simple, but/and/yet all-encompassing rules (partly because I’m not very good at remembering lots of things :smile: ):

You can start anywhere.

“If it sounds good, it is good.” — Duke Ellington

“Everything should be as simple as possible, but not simpler.” — Albert Einstein

If it is hard, it must be wrong.

Two Dead People

Category:

Any fool can criticize, condemn, and complain — and most fools do.

But it takes character and self-control to be understanding and forgiving.

I got that from the book “How to Win Friends and Influence People”. (This book is very dear to me because it helped me change the way I view other people — it changed, to a large degree, my cynicism.)

In the same chapter where I got that quote, the book says this:

“God Himself, sir, does not propose to judge man until the end of his days.”

Ahhh!

Does that mean it is okay to judge people when they are already dead?

Okay… Let’s do some judging of some dead people!
