Coming from the world of selling fire trucks I’m used to selling necessary solutions to customers in need. The stakes are high. If the truck doesn’t perform best case scenario it’s a false alarm. Worst case scenario someone, many people, die.

Let me tell you a bit about fire trucks.

A lot of people think that a fire truck is a fire truck. That there is some factory where fire trucks are made, carbon copies of one another, varying only in what they carry – water, a pump, a ladder. That’s not the case. Every truck is custom engineered, designed, and manufactured from scratch. Things can go wrong. In a world where response time is everything, you don’t want something to go wrong. Not with the fire truck. Not when everything else is going …

I am potentially one of the least technical people in my generation. I’m 30 and I am afraid of my cellphone, my laptop, Netflix, the microwave…. Okay, afraid is maybe a strong word, but baffled by them at the very least.

In high school, while my classmates wrote most of their papers and assignments on the computer, I insisted on writing everything out by hand and only typed it out afterwards if absolutely required. It wasn’t that I had issues with typing – my mom who worked as an administrator for many years made sure that I learned to type from a very young age and I type quickly with a reasonable amount of accuracy. I just felt that writing by hand kept me more “connected” to the words I penned. Simply, my name is Sarah and I am a Luddite.

After high school I studied journalism for a couple of years and then entered the workforce into a number of different jobs, such as in sales and marketing and it became necessary …

I love finding out new things about MySQL. Last week, I stumbled on a query that had the phrase “SOUNDS LIKE” in it. Sounds made-up, right? Turns out MySQL is using a known “soundex” algorithm common to most databases, and popular in use cases in geneaology.

The basic idea is that words are encoded according to their consonants. Consonants that sound similar (like M and N) are given the same code. Here’s a simple example:

(“soundex” and “sounds like” are different ways of doing the same thing in these queries)

MariaDB> select soundex("boom");
+-----------------+
| soundex("boom") |
+-----------------+
| B500            |
+-----------------+

MariaDB> select soundex("bam");
+----------------+
| soundex("bam") |
+----------------+
| B500           |
+----------------+

MariaDB> select soundex("bin");
+----------------+
| soundex("bin") |
+----------------+
| B500           |
+----------------+
