Never Rewrite: Software Engineering & AI Coding

Isaac shares a story about a project where a quick MVP was built to send text messages to users. As the project gained more partners and volume, it became clear that the system couldn't handle mass texting at scale. A small change in the architecture caused some batches of text messages to be reprocessed multiple times, resulting in some users seemingly receiving an excessive number of texts. Howe...

Isaac and Jeffrey discuss the myth of the Boy Scout rule, which is the idea of leaving code better than you found it. Isaac shares his experience of encountering problems when trying to follow this rule in a codebase with no test coverage. He explains how fixing one issue led to unintended consequences and a cascade of errors. They emphasize the importance of being cautious when making changes in...

Isaac and Jeffrey discuss situations where software development teams are pushed to have fewer, larger releases. They highlight the challenges of big release-driven development and the need for careful planning and more QA before each release.

We check in with Dustin Rea, head of Red Hook Agency, to discuss where White Label CRM is with their 'turnaround story' - how they're handling 'bug hell', scaling issues, and what their trajectory is now.

Isaac and Jeffrey discuss the potential of AI-driven testing and code generation. They reference an article by Codium AI, which explores the use of AI to generate tests and increase code coverage. While the generated tests may not be perfect, they can serve as scaffolding for legacy code and help identify areas for improvement. The conversation also touches on the idea of using AI to provide busin...

Isaac and Jeffrey discuss the mindset of writing your job out of existence. They explore the idea that being irreplaceable can be a trap and that making your current role disappear in a positive way is the key to career growth.

Isaac and Jeffrey discuss the topic of doing full rewrites when it comes to architecture. They explore a case where a client needed to move from a single EC2 instance to a more stable system with load-balanced instances. They discuss the parallels between rewriting code and rewriting architecture, and the challenges and risks involved.

Isaac and Jeffrey discuss the 'two clock problem' as a metaphor for software rewrites. They explain that adding a new system doesn't improve understanding if you don't know how the current system is wrong. They also emphasize that rewriting a system without understanding the current system is costly and may not be worth it. Instead, they suggest spending more time understanding and documenting the...

Company culture can have a significant impact on the style of code delivery. A rigid and bottlenecked code review process can slow down code delivery and create frustration. On the other hand, a collaborative and open culture can lead to faster and more efficient code delivery. It is important to strike a balance between code quality and speed of delivery. Perfect code that doesn't solve the probl...

In our new series 'fulfilling Fridays', Jeffrey shares a fulfilling software project he worked on at Guaranteed Rate, a mortgage broker company.

Isaac and Jeffrey discuss falsehoods that programmers believe about projects. They explore the misconception that the project will solve the stated problem, highlighting instances where the delivered software did not actually solve the problem. They also discuss the importance of understanding how the user will use the software and the need for clear communication and feedback loops to ensure that...

In this episode, Isaac and Jeffrey discuss falsehoods that programmers believe about projects. They explore assumptions such as projects having defined beginnings and endings, the role of priorities in project work, and the importance of clear communication and feedback. They also touch on the challenges of working on successful projects that transition into ongoing maintenance and the consequence...

Isaac and Jeffrey discuss the flight to maintenance work as a safety option from the manager's perspective. They explore different perspectives on maintenance work and the value of taking on such work. They emphasize the importance of understanding the reality of the system and approaching maintenance work as an opportunity to solve real problems. They also discuss the role of accountability and c...

In this conversation, Dustin Rea discusses the challenges faced by one of his clients who has a CRM. The CRM is built on a legacy codebase with issues in quality, scalability, and deliverability. The team has been working on improving the system, but there are still problems with emails, SMS, payments, and automations. The company is mission-driven and relies on the CRM to run their business, so r...

They also talk about running out of failure stories and the importance of finding interesting guests. The hosts discuss the concept of forcing functions for successful rewrites and the risks associated...

Jeffrey and Isaac discuss the concept of ‘doing more with less.’ They explore the initial visceral reaction to this idea and highlight the importance of doing less of things that don't matter. The impact of layoffs and the need to work smarter, not harder, are also discussed. The hosts emphasize the value of having honest discussions and creating a culture of transparency. They caution against bur...

Jeffrey and Isaac discuss their stance on 'never rewriting' given the possibility of AI making rewriting faster, cheaper, and less risky.
