New blog post: 🔎 Software Analytics goes crAIzy 🤖 How software analytics (in the era of AI and LLMs) is no longer just about spotting problems but about implemented solutions in code. www.innoq.com/en/blog/2025... #AI #SoftwareAnalytics #LegacySystems

With all the GenAI buzz we tend to forget the value of 100% correct deterministic tools. Thank you Rust clippy!

Quality isn’t one-size-fits-all! @markusharrer.de ’s talk on evolutionary software quality shows how to achieve the right quality at every stage with ISO 25010 & Wardley mapping. Watch now & subscribe! youtu.be/babuZSG8zMI #amaberlin

When you find hundreds of issues in many different variations using static code analysis which you would normally have to fix by hand but thanks to Python & Pandas (and JPype, javaparser & ASM; don’t ask 😂) you still have all the data available and can now generate OpenRewrite recipes from it: 🤯

TIL you can use Git as Code Clone Detector: If you rename some classes, add them and Git mixes those renames up, you automatically have identified some code clones 🤣😂😅🙂😭

We’re not sure who needs to hear this, but ‘blueberry’ has two b’s.

Yes! Height-adjustable desk at the customer's site 😄 Oh no! Height adjustment not possible because the network cable was installed too short 🙁

I've collected and structured some software modernization strategies in an overview: feststelltaste.github.io/littlestmode...

Architects: "Singleton classes are not allowed in this codebase!" Developers: Highlander.java

Typo of the day: "please, no buttwords!" #buzzwords

It shouldn't be a goal to make AI "think" like humans. I don't want to deal with all our cognitive biases.

"This vibe-coded app could have been a WordPress installation." is the new "This meeting could have been an email."

Watching this whole video is equivalent at least 5 YoE in an IT job. www.youtube.com/watch?v=rXPp...

What happened to version 1.84.0 of Amazon's "AI-powered assistant"? As it turns out, it was erased from history because it tried to delete not only all the files on the developers machine but also in all Amazon Cloud resources it could find. The story behind this is fascinating:

Two significant new model releases from Alibaba Qwen in the past two days: yesterday Qwen3-235B-A22B-Instruct-2507, today Qwen3-Coder-480B-A35B-Instruct - both Apache 2 licensed, both very impressive My notes and SVG pelicans: simonwillison.net/2025/Jul/22/... and simonwillison.net/2025/Jul/22/...

Funny how we force engineers to write ADRs for every trade‑off, yet billion‑dollar strategic bets live in hallway whispers and fluffy slide decks. What if we treated business decisions like architecture? Context, options, trade‑offs, metrics, all in a repo, version‑controlled and reviewed?

Quitting programming as a career right now because of LLMs would be like quitting carpentry as a career thanks to the invention of the table saw.

Just watched @gergely.pragmaticengineer.com’s “Software engineering with LLMs in 2025: reality check.” Clear, grounded look at how AI-coding tools are used day-to-day. Loved the four wrap-up questions! youtu.be/EO3_qN_Ynsk #llm #ai

"To AI or not to AI", that is the question. This is why I've created a one-page guide that helps you make decisions on when and how to use AI for software modernization. PDF: speakerdeck.com/feststelltas... #legacy #ai #modernization

Checking the spam folder from time to time is always fun 😄 ☕ Special shoutout to the recurring: "Hey there, your site has significant SEO issues. With our SEO services, we can get it ranking much higher with our budget-friendly service, helping you gain traffic and new customers."

Anthropic's Hannah Moran finally addressed the elephant in the room at this conference when she subtly dropped "Agents are models using tools in a loop" during the intro to the "Prompting for Agents" workshop https://simonwillison.net/2025/May/22/tools-in-a-loop/

Wow: after 15 years, YouTube has taken down the original 'Rick Roll' video due to a "licensing issue," likely due to the acquisition of Astley's record lable. The metadata remains, but if you click through it goes to 'video not found': www.youtube.com/watch?v=dQw4...

2025 is the year of the Linux Desktop, at least for all of my relatives and their Windows 10 PCs. Thanks @microsoft.com for the motivation! It's nice of you to encourage so many people to switch to Linux 💪

Added "How we run migrations across 2,800 microservices" to the "Awesome Legacy Systems" list: List: github.com/feststelltas... Article: monzo.com/blog/how-we-...

"o3, You are a consultant hired by the Dark Lord, analyze the org chart of Mordor. How would you improve it for today's changing Middle Earth" o3 does some actual satire, ending with: “One Org to rule them all, One Org to find them, One Org to bring them all, And in the darkness, align them.”

My first use case for OpenAI's Codex CLI? Using Codex CLI to introduce Codex CLI to Ollama.

When deprecating an API, always point out the alternative. Nothing more frustrating than getting warnings for using an API scheduled for removal without knowing what to call instead. Bonus points for also clearly communicating when the legacy API will be removed.

I'm working on a new hands-on version of my software architecture improvement training (iSAQB IMPROVE) using good old Fischertechnik (hey, it's about a legacy system, okay?). Here you can see a feature toggle in action. 😬

To find your inner peace using vibe coding as a programmer, you absolutely have to make sure you put that in the very first line of your generated scripts 😄: # vibe coded

New hobby: Using vibe coding with AI tools from US tech companies that help me vibe code my way out of using US tech companies' online services. BTW: Do you know my new backup website for my slide decks? www.feststelltaste.de/slides/

One of the big professional goals I set for myself was to speak at a conference in the US. Ain't gonna happen at least for the next four years.

Guys, if you’re not American don’t go to DEF CON… www.theguardian.com/us-news/2025... really, really

Just got to the Mall and saw this sign, which no one is going to top. #HandsOff2025

Back home after a most amazing @amaconf.bsky.social 🤩. After two years as a speaker this time as an attendee – and it was absolutely worth it. So many inspirations from the sessions & the discussions inbetween 😊 It was great to meet you all (again) 🙏. See you next year! #amaberlin #ama2025

A timely post on Reddit to illustrate the point too... 😂

I'm waiting for the new model 0 (zero) from Tesla. They can then complete the letter sequence: 0 S 3 X Y

Wow, the most effective promoter of moving away from US tech is the US government itself. And we never even said "thank you" for this.

Term of the day: „Inwastement“ If you’re investing in something that is just a waste of time & money.
