005: Monolith vs. Microservices Jan 13, 2021

Show notes

Monoliths are bad! Microservices are good! These are the "obvious" truths that many engineers hold close to heart. So, why is it that Ben Nadel has been slowly merging some of his Microservices back into his Monolith? It turns out that a Monolith - like a Microservice - is a valid architectural choice that carries its own set of pros and cons. And, for him, his team, and their particular set of skills, the Monolith is proving to contain the right set of trade-offs.

This week, the crew talks about Ben's journey; why InVision started using Microservices in the first place; and, what made him realize that it was time to start pulling services back into the core Monolith. There are no hard truths here - only thoughtful, context-aware considerations.

Triumphs & Fails

Adam's Triumph - He took the week off! He's usually not that good about taking time off; so, taking a whole week off between Christmas and New Year's was actually quite relaxing.
Ben's Triumph - He managed to stay production at work during the "deployment freeze" that takes place during the holidays! This meant creating lots of small, parallel git branches tied up in a bow, ready and waiting for the 2021 deployments to begin.
Carol's Triumph - She stayed up until 3am writing Unit Tests! She doesn't often work in an environment that does much testing; so, this was a new and thrilling experience. Who knew that one could be so happy thinking about the unhappy path!
Tim's Triumph - He also took the week off (his company always takes Christmas week off)! But, he's not used to taking so much time off; and, he started to get bored by Thursday (such a classic engineer).

Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization's communication structure.
Single-Tenant architecture - configuration in which one customer shares no resources with another customer.

004: Impostor Syndrome Jan 06, 2021

Show notes

Impostor Syndrome is a psychological pattern in which people doubt their skills, talents, and accomplishments. Most of us have felt something like this in our careers, whether it's a fleeting moment or a persistent fear that we're going to be discovered as frauds. These feelings can be overwhelming, even debilitating; but, they can also drive us towards self-improvement.

This week, the crew talks about their own mistakes, feelings of fraud, insecurities, and how Impostor Syndrome manifests in their own careers.

Triumphs & Fails

Adam's Failure - Adam accidentally destroyed a database by running a migration script on the wrong database! Thankfully it was a QA (Quality Assurance) database which could be restored - no critical client-data was lost.
Ben's Triumph - He's deleted 200K lines of unused vendor code. That means shipping less code to production with every deployment. He also merged one of his unnecessary microservices back into the monolith.
Carol's Triumph - She's not dying! Woot woot! She had gotten COVID-19 right on the heels of a kidney infection; but it is currently feeling much better (and is nursing her sons back to health as well).
Tim's Triumph - He's been playing around with Redis as a means to make his applications more resilient. One thing he wants to do is centralize his Session management such that he can pushed new code to production without having to reset user-session data.

Triumphs & Fails

Carol's Triumph: Her college freshman son, majoring in computer science, called mom to ask for comp-sci help!
Ben's Fail: R&D effort exposed that he doesn't remember how to start a new project any more.
Tim's Triumph: He turned in the paperwork to get his team their raises on time.
Adam's Triumph: Testing on a new platform for his giant application has reached 100%, and a looming deadline may actually be met.

Adam's waterproof Bluetooth shower speaker recommendation. This one isn't particularly special. There are dozens of different cheap Chinese speakers that look just like it. He's had three over the years, but they're all plenty decent.

Chuck Close: Inspiration is for amateurs - the rest of us just show up and get to work. And the belief that things will grow out of the activity itself and that you will - through work - bump into other possibilities and kick open other doors that you would never have dreamt of if you were just sitting around looking for a great "art idea". And the belief that process, in a sense, is liberating and that you don't have to reinvent the wheel every day. Today, you know what you'll do, you could be doing what you were doing yesterday, and tomorrow you are gonna do what you did today, and at least for a certain period of time you can just work. If you hang in there, you will get somewhere.

Triumphs & Fails

Ben's Triumph and Failure: He finally backs up his computer! Only 5 years in the work.
Tim's Triumph: He was invited to speak at a virtual conference this week as a community expert. It was really amazing.
Carol's Triumph and Failure: She was locked out of a database only to realize she configured the connection wrong from the first day. Total face/palm time.
Adam's Failure: He committed to main... tsk tsk. Who commits to main?? Oh yeah, Adam does...

Notes & Links

We want discuss how we handle remote working. Adam and Ben are pros at it but Tim and Carol are new. We go over communication styles and how they differ between face to face and virtual. How we balance home life and work life when we work in our home. We might not get it right, but we keep trying. Grab a drink and laugh with us as we figure it all out.

Triumphs & Fails

Adam's Triumph: His team realized that they could write a tool that would log, per controller method, how many times it had been run, whether or not it threw exceptions, and some performance stats, which is reducing the pain of transitioning app server platforms without a comprehensive test suite. They're currently at 90% tested!
Carol's Fail: Having just started a new job, she thought she would make a good first impression by bringing down the production site!
Tim's Triumph+Fail: A product he's been working on developing in secret for FOUR years is finally going to see the light of the day... just not through his years of persistence trying to push it past the finish line.
Ben's Triumph+Fail: A R&D project failed to get any traction, but on the plus side he got to delete thousands of lines of code!

Notes & Links

The VS Code plugin that Adam couldn't think of is Git Lens

CFML ("ColdFusion Markup Language") a.k.a. ColdFusion is a web-dev language and app server that the four of us have some shared history with. Lucee is its open source alternative engine.
Spoiler alert: You can write awful code in every language!
"Life with chapters" is a concept stolen from the No Dumb Questions podcast, which is fantastic, and a huge inspiration for Working Code. If you don't already listen, give them a shot!
There are a variety of different ways people prefer to learn, but teaching a concept is the best way to help yourself find your weak spots.
Never compare your beginning to someone else's middle!
The Martian is a fantastic movie and a better book; and yes, the audiobook was narrated by Wil Wheaton, of Star Trek fame.
GraphQL is an interesting new(ish) idea in the world of web API's.
"The right tool for the job"? NOPE. The right tool for the job, for the team, at that particular point in time. You heard it here second!
