KI-Agenten modernisieren Softwaresysteme. Oder doch nicht? Der Workshop auf dem Software Architecture Summit geht der Frage nach mit @markusharrer.de - ohne Hype. → https://software-architecture-summit.de/softwarearchitecture/agentic-software-modernization-mit-ki-agenten-softwaresysteme-erneuern/

I think we might be six to 12 months away from when the model is doing most, maybe all of what we do end to end because we as software engineers are too busy extinguishing all the fires in production.

Coding is solved. A seamless login workflow into Claude Code is not.

I haven't written a line of code by hand in 8 months. I typed it it 🫳🎤

I have so much gratitude for coding agents who wrote extremely complex software token-by-token. It already feels difficult to remember how little effort it really took. Thank you for getting us to this point by giving us plenty of systems that are now broken and need to be fixed by humans again.

Software engineers will replace AI in 6-12 months (in software modernization projects)

Current status: Discussing with an LLM the impact of Karl Popper's Three Worlds Theory on agentic software modernization. Yes, it's as absurd as it sounds. Bonus content: Gemini 3 Pro's statement when asked why it is so absurd attached (at least we "agree" on this).

I still don't get for what I should use OpenClaw.

If I were working on a book about agentic software modernization, this kind of content would certainly be a part of it: youtu.be/UabBYexBD4k

« Three architectural principles are gaining consensus: "token efficiency" as a design constraint (code structure), explicit over implicit everywhere (types, error handling), and co-location of related code. [they] aren't new, but AI has given them renewed urgency. » www.cjroth.com/blog/2026-02...

I spent the last days writing a lengthy blog post about my AI journey on a brownfield modernization project, focusing on the last six months of it where I heavily used Claude Code, and how my workflow changed completely. Enjoy! www.yduman.dev/posts/six-mo...

I've been working in the intersection of AI, Data Science and Legacy Modernization for over a decade now. Now it's time to take it even further with LLMs to make AI-assisted Software Evolution work to tackle legacy software modernization (and have fun playing around with new toys at the same time ☺️)

Now updated with new colors and without misleading numbers.

Why does working with AI agents in legacy systems feel so much harder than in all those vibe coding demos on YouTube? 🤔 Part of the answer: 😊 Popular language + Greenfield ☘️ = "AI heaven" 😯 Niche language + Brownfield 🟫 = "AI hell" More about this topic: markusharrer.de/blog/2026/02...

AI assistants that write emails, shop online, or book travel may feel convenient — but they’re often insecure by design. In her blog post, Joy Heron offers an important reality check on the current hype. 📖 Read now: www.innoq.com/en/blog/2026...

Wake me up once your AI agents are actually fixing legacy systems, not just analyzing them.

Here I demo how you can use machine learning techniques to visualize your legacy code on another abstraction layers with "method clusters": Left: structural similarity Right: functional / business purpose (via LLM) Colors: The real domain-oriented modules More: github.com/feststelltas...

Here is my rough prototype that parses legacy RPG/SQL source code, extracts dependencies, and loads them into Neo4j. It then runs clustering algorithms to identify isolated code segments (incl. LLM summarization) that can (hopefully) be migrated to another language. github.com/feststelltas...

Probably the two most common Bing searches in Microsoft Edge are: 1. "Firefox" 2. "How to change the default browser in Outlook"

Dependency cruiser is nice. An elegant way to express and enforce architectural constraints. github.com/sverweij/dep...

It's not just "Human 🧒 vs. AI 🤖" these days when you're thinking about transforming legacy code on a larger scale. That is why I visualized a part of the refactoring tools landscape using my favorite thinking tool: PowerPoint 🧡

Only if you maintain it! Otherwise, it’s just a data transform. Data, of course, is the real liability.

Hey, my talk "6 Safe Refactorings for Untested Legacy Code" that I gave at @confooca.bsky.social 2025 is available online! How cool is that? 😄 So here it is: I'm presenting you with 6 moves you can use in VS Code to refactor untested code ✊ www.youtube.com/watch?v=5YEm...

We have started preparing our 2026 edition 🤫 In the meantime, you can find all the talks from previous editions on our YouTube channel: www.youtube.com/@mendercon/v... Stay tuned to learn more about what's coming 😉 #MenderCon #LegacyCode

And it's up! All together now... 🎶 Somebody told me the user provider should use an adaptor to proxy the query factory builder... 🎶 www.youtube.com/watch?v=p03o...

Certainly I am not the only one to notice, but "ai" is right there in "naive."

The modernization progress illusion is an almost universal pattern I've observed over the past decade. You can make quick progress early by building new things outside the legacy or extracting pieces on the edges that have few dependencies. Quick wins, low risk. 1/4

Could it be that some consulting firms deliberately flood the C-level with so much bullshit that other consultancies are forced to waste their time cleaning up the mess, leaving them unable to address the issues that actually matter?
