What I Learned at Work this Week: AWS Transfer Family

In my experience, a lot of computer programming is about abstraction. When I first started learning, I coded in a repo that already had a testing infrastructure in place so that I could check my work. I didn’t have to write the tests or even understand how they worked, nor…

What I Learned at Work this Week: pytest fixtures

Loyal readers might be familiar with a certain Python script in my workplace. If not, here’s what you need to know: it’s super long and hard to edit because it has so many things going on. Thanks to some additional resources and oversight now being provided to my team, we’re…

What I Learned at Work this Week: Algos Never Stop

A good friend of mine recently graduated from coding boot camp and is now dealing with everyone’s favorite part about being an engineer: interviewing. She’s asked me for help with a couple of algorithm problems and I think I’ve been more of an impediment than anything, so it seems as…

What I Learned at Work this Week: Terraform Basics

Sometimes at work, I get requests that I can “freestyle.” I don’t bother to consult any documentation because I know how all the pieces fit together and even if I’m wrong about the way I think my code will work, I know how to debug locally and in production. …

What I Learned at Work this Week: Formik in Production

After I wrote my blog last week, I got a great response from one of my company’s front end engineers. She encouraged me to check out her team’s Formik components since they put the concepts I’ve studied into practice. I’m always happy to get guidance from another engineer, so I…

What I Learned at Work this Week: React Form Validation with Formik

Formik is a React framework that makes our form-writing lives easier. I’m in the process of learning about it this week, but really I should have learned about it last week when an enthusiastic coworker offered to give me a crash course. I should have understood that their enthusiasm was…

What I Learned at Work this Week: OOMKilled Kubernetes

Last week, I learned about how to write a DAG in Airflow. That knowledge came in very handy this week, as about five different Airflow-related bugs were sent my way. One particularly sticky problem was a script that failed five days in a row because of a lack of memory…

What I Learned at Work this Week: Airflow

Here’s the experience I generally have when my company starts migrating a process to a new service: Hear about the change at an all-hands. Understand nothing that is said because it all has to do with graphs and clouds and clusters and streams. …

What I Learned at Work this Week: Arrange-Act-Assert

My favorite part of my job is writing familiar code in familiar codebases. I like being in a place where I know how most of the pieces connect, recognize the patterns, and have my environment set up so that I can run code locally and debug. It’s a special feeling. …

What I Learned at Work this Week: Parsing JSON with PostgreSQL

I think that my favorite way to learn is to run someone else’s code and log/debug/edit it to understand how it works. I got that opportunity this week when I was trying to figure out how certain rows were filtered in a Postgres database. The query looked something like this: …
