🔥 Clean Code, Legacy Systems, and Lessons Learned After 40 Years in Development 🔥 I’ve always admired Robert C. Martin (Uncle Bob) for his clarity on what makes code maintainable. His books Clean Code and Clean Architecture resonate deeply with me because they articulate principles I’ve instinctively applied throughout decades of software development. I’ve seen languages evolve to address weaknesses in earlier ones—issues that experienced developers often mitigate through disciplined practices. But here’s my confession: ❌ I didn’t adopt Test-Driven Development (TDD) early on. Why? Because I was a solo developer maintaining a massive, mission-critical codebase under tight deadlines. Refactoring for TDD felt impossible without risking delivery schedules. ⚠️ The result? My Borland C++ 5.2 (pre-C++98) codebase became almost unchangeable without introducing unforeseen consequences. Every modification carried risk. That pain point led me to Michael Feathers’ book Working Effectively with Legacy Code. His insights were a revelation—I wished I had applied them sooner. Years later, armed with Visual Studio and TFS for source control, I began refactoring small sections and adding unit tests, creating islands of safety in a sea of legacy complexity. Without those tools, I would never have attempted it. 💡 One challenge we all face as developers is the lure of “shiny new toys.” With the ISO Committee for C++, new features regularly tempt us to refactor working code just to use the latest thing. In my experience, this should be avoided unless it improves clarity or testability. 👉 Spending hours making code “shiny” is time wasted that could be used making untested code testable. ✅ Takeaway: Clean principles aren’t just theory—they’re survival tools. If you’re working on legacy systems, start small. Add tests where you can. Refactor incrementally. Your future self will thank you. 💬 Question for the community: Have you faced similar challenges with legacy systems or TDD adoption?

Something that is common in software development is modules being removed from the business rule and just commented in the code or having the function removed from the screen, but it remains a mess in the back-end, I once maintained a system that had thousands of lines that were no longer used, but still in the code.

Unpopular opinion: Code reviews are all about finding issues. Sure knowledge sharing through review comments is a great channel for growth. But you don’t always get new information from reviews. Working down this logic, only other functionality left of code reviews is finding the bad. Make sure the code doesn’t break production. Point out bugs, validate requirements, code smells, and sometimes architectural hindsight missed from design reviews. Anything that I missed for this aspect of software development? Comment below.

The price of mandatory code reviews: In every company I worked for in the last 15 years, we had mandatory code reviews (at least one, usually two reviewers per PR). Over the last month, I’ve begun to reconsider this ‘law’. For the first time, I’ve met production teams that don’t have mandatory code reviews. For example, at Pylon (YC S21) , engineers merge their own code and only request reviews if they need input, think they have a risky change, or are still onboarding. Their thought process is: if we hire skilled engineers and trust them, there’s no reason to bottleneck every change with mandatory reviews. This actually makes a lot of sense, but I still felt uncomfortable. So I decided to check the data (400+ companies and 3000+ engineers on Weave ) in the past month to answer 5 questions: 1. Are teams without code reviews actually faster? 2. Are code reviews reducing bugs? 3. Does the quality of code reviews matter? 4. Does the turnaround speed of code reviews matter? 5. How do top organizations work? The TLDR: You go MUCH slower with code reviews. You also have MUCH fewer bugs :) The biggest gains happen between 0 and 0.5 reviews per PR - after that, diminishing returns kick in. I think it makes sense - for some PRs it’s ok to not have mandatory code reviews. Let’s say you want to improve a log message - it’s very annoying to need to ask people to review it.

I am a big fan of rethinking old assumptions. In software engineering, one of these old assumptions is code review upon pull request (PR), a model that many engineers were weaned on through GitHub and open source that is now second nature. It's good to see leaders like Anton question if it really has to be that way. My quibble with this analysis though is it assumes a false choice: either the current PR model—an old-school, Waterfall-style gate that slows you down but the price you have to pay for quality—or YOLO where you let it rip by moving fast and breaking things. There are other options, which I wrote about in Beyond GitHub Culture: Why Your Team Should Reconsider Pull Requests. Link in the comments.

Mandatory code reviews often trade flow for safety/control. If teams are only using PRs as gates, then yeah, of course they’re going to slow down. That’s just the nature of asynchronous feedback loops. If we change the view from gating for safety/control to optimising for learning. Tht focus shifts to how we design fast feedback loops. Increasing the speed of learning naturally builds redundancy within org and inherently amplifies flow and quailty.

AI code reviews close the gap between speed and quality. We find merge time improves by 85% once AI does the review.
