A screenshot with this text: "The pipeline had degraded to the point of collapse. On the surface, the problem was that it converged on a choke point that was easy to saturate and hard to scale. But the real issue wasn’t having a bottleneck. It was pretending that there wasn’t one, treating back-pressure signals as a nuisance, and letting an AI-induced productivity anxiety run unchecked."

Why the faster tech evolves and AI advances, the more valuable computer science fundamentals become. Understanding principles beats chasing trends.

One of the interesting parts about software engineering is that each domain you work in requires re-asessing every pattern and best practise that seemed set in stone in other domains.

Must say it's been a lot easier to convince the AI to stop than the average human.

I have Copilot (+ Claude) stuck in an infinite loop of refactors with small "improvements" to its own implementation of a relatively simple prompt. Feature parity with human devs is one step closer.

The more we lean into vibe-based coding, the clearer it becomes that we’ll still need good operators to keep everything sane and under control

I'm not sure I'd advise solving that entire list of things up front. Pragmatism would tell you to fix those that you actually need, and at most have a plan for how would you address the rest. I say this because I've seen several points (e.g code structure, devops processes, modules boundaries..) ->

Galo Navarro @varoa.net · 14/04/2025
I do see people obsess with finding Design Pattern as silver bullet. I generally agree with the article (gist: "be pragmatic"). Although IMO the conclusion dilutes the point ("go Modular-First" induces the same confusion on the reader: "oh here is a capital-P-Pattern I can apply"), plus ... ->

Galo Navarro @varoa.net · 14/04/2025
I don't get the point with seeking a capitalized Design Pattern as a silver bullet. It's not the pattern you chose on day 1. Nobody can anticipate how a complex system will evolve over time. It's about consistently taking design decisions that optimize for ease of change, and adapt to new info

Oh even further. There is no way to justify paying a human to produce boilerplate And the shift to higher value work (which I agree is more fun, but YMMV) is far from a clean 1:1 mapping of skills

When I wrote about "AI will choke delivery pipelines", no-Fri-deploys was one of the practises I mentally labelled as AI-unfriendly. Interrupting the flow of code on Fri creates a glut for Mon. And bundling changes tangles latent defects, making troubleshooting harder. varoa.net/2025/04/07/a...

When bundling $thing2 into $thing1 looks like a good opportunity, that's the signal for NOT doing it. If they looked like bad opportunities overengineering & overscoping would never happen.

When the AI spits 200-400 lines of functiona code based on a prompt, forcing a whole commit, pr, test, [review], merge cycle is just too much friction holding people back. Screenshot is from my piece varoa.net/2025/04/07/a...

I mention the DORA report in the piece I published today. The report has a page about AI impacting sw delivery negatively. The recommendations (screenshot) about smaller changelists and robust testing make sense, but I'm somewhat skeptical that they are viable ->
