Why Mary Is the Best Promoter of Culture — My Favorite Catholic Things
In the early 1900s, Adams, a Protestant who had spent much time living in Europe, wrote about the extreme power wielded by the Virgin Mary:

The twelfth and thirteenth centuries were a period when men were at their strongest; never before or since have they shown equal energy in such varied directions, or such intelligence in the direction of their energy; yet these marvels of history – these Plantegenets [a dynastic family of kings]; these Scholastic philosophers; these architects of Rheims and Amiens; these Innocents, and Robin Hoods, and Marco Polos; these crusaders who planted their enormous fortresses all over the Levant; these monks who made the wastes and barrens yield harvest – all, without apparent expedition, bowed down before the woman.

What Adams recognized over a century ago as he walked through the cities, churches, cathedrals, and cemeteries, was that the height of European culture was centered around devotion to Our Lady. In the places where European culture soared, so too did devotion to Our Lady, and perhaps vice versa, where devotion to Mary soared, so too did culture.

Out of Pride and into Humility - Community in Mission : Community in Mission
In yesterday’s post, we considered the twelve steps of pride set forth by St. Bernard of Clairvaux. In escalating ways, the twelve steps draw us to an increasingly mountainous and enslaving pride.

St. Bernard also enumerates the twelve steps to deeper humility and it is these that we consider today. As with yesterday’s post, the list by St. Bernard is shown in red, while my meager commentary is shown in plain, black text. To read St. Bernard’s reflections, consider purchasing the book Steps of Humility and Pride.

The Wrong Abstraction — Sandi Metz
I've been thinking about the consequences of the "wrong abstraction." My RailsConf 2014 "all the little things" talk included a section where I asserted:

> duplication is far cheaper than the wrong abstraction

And in the summary, I went on to advise:

> prefer duplication over the wrong abstraction

This small section of a much bigger talk invoked a surprisingly strong reaction. A few folks suggested that I had lost my mind, but many more expressed sentiments along the lines of:

> This, a million times this! "@BonzoESC: "Duplication is far cheaper than the wrong abstraction" @sandimetz @rbonales"
— 41 shades of blue (@pims) March 7, 2014

The strength of the reaction made me realize just how widespread and intractable the "wrong abstraction" problem is. I started asking questions and came to see the following pattern:

Programmer A sees duplication.
Programmer A extracts duplication and gives it a name.

This creates a new abstraction. It could be a new method, or perhaps even a new class.

Programmer A replaces the duplication with the new abstraction.
Ah, the code is perfect. Programmer A trots happily away.
Time passes.
A new requirement appears for which the current abstraction is almost perfect.
Programmer B gets tasked to implement this requirement.
Programmer B feels honor-bound to retain the existing abstraction, but since isn't exactly the same for every case, they alter the code to take a parameter, and then add logic to conditionally do the right thing based on the value of that parameter.

What was once a universal abstraction now behaves differently for different cases.
Another new requirement arrives.
Programmer X.
Another additional parameter.
Another new conditional.
Loop until code becomes incomprehensible.
You appear in the story about here, and your life takes a dramatic turn for the worse.
