Last year, I wrote about A Year In Open Source, and I wanted to wrap this year up with another reflection after having hundreds of hours over the course of 2022 engaged in giving back. I've had the pleasure of mentoring colleagues & friends; of contributing additions to popular open source libraries like Nebula Logger, Trigger Action Framework as well as my own repositories; of reading and continuing to hone my own skills. I was also a guest speaker at an internal symposium for Open Source we...| www.jamessimone.net
At the end of 2020, I decided to take 2 weeks off of work at the end of the year. I was very fortunate to be able to do so, and I found myself in the position of wanting to give back. I'd had to replace DLRS within the org for the consulting company I was working for several months previously, and the idea of creating a more performant rollup engine was an alluring way to do so.

This exercise will also highlight a curious junction between Test Driven Development (TDD) and Domain Driven Design (DDD) - which is to say that if the functionality that you're working to refacto...| www.jamessimone.net
Expressing intent through naming is a challenge, but well-named methods can help to expose even the most complicated of programming mechanisms. In programming, as in life, context is key - let's explore how naming can elevate the intent and rationale behind code! Whether you're just beginning your programming journey or you're a veteran programmer of many years, it's my hope that there's something in this post for everybody.| www.jamessimone.net
A few months ago I was tasked with replacing Declarative Lookup Rollup Summaries (DLRS) in an org suffering from frequent deadlocks. Rollup summary fields in Salesforce are plagued by severe limitations -- only being available on master-detail relationships being just the start of the list. Read on to learn about how I built Rollup to assist in orgs looking for DLRS-like flexibility with a much smaller performance overhead, complete with elastic scaling (go fast when you need to, slow when th...| www.jamessimone.net
