Yep, I occasionally quote Gall's Law from 1975(!): "A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a working simple system."

Don’t let influencers fool you, coding with AI (Claude Code / Codex / Gemini) still takes a lot of work. You may be more productive, but expect long hours and many late nights.

It’s like creating a 15-minute short using AI. It may look easy, but it often takes weeks of trials to produce that video.

If you (AI-assisted) specify not only the goal but also the β€œhow,” including the technology stack, then the LLM doesn't choose for itself, does it?

Go, GPT, and the Trap of Sycophancy | Software 7

Two entirely different use cases: an AI supposedly working at PhD level acting as an echo chamber for your biases, versus giving it clear specs where it excels at code generation.

Using the ancient strategic game Go (Baduk/Weiqi), not the language.

Local LLMs Show Significant Gains in Agentic Coding | Software 7 Local LLMs have caught up: I compared cloud vs local on the same agentic coding task, and the local run held up surprisingly well.

Local LLMs have gotten much better at agentic coding.

Complexity! Funny - Gall's law is also 50 years old:
"A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a working simple system."

2025 Reflections | Software 7 AI dominated 2025, but complex systems don't care about hype. Reflections on what actually worked, what didn't, and why traditional engineering principles aren't going anywhere soon.

I've blogged a little about some thoughts on the year 2025.

I usually stop reading an article when I see a bar graph that only shows the upper part of the bars to make the effect (increase or decrease) seem more dramatic.

Good question: Even though most people nowadays probably think differently about it, I think it's always good to learn it if you're interested in how systems work under the hood: memory, stacks, heaps, etc.
No?

More working hours may also be required, as according to this AI startup, AI can accumulate so much technical debt after just a few months that it leads to a significant slowdown in product velocity?

It would be interesting to know how significant productivity gains actually are over longer periods of time in non-trivial environments (including maintenance, bug fixes etc), based on real data. It may not look so rosy.

At first, I thought (somewhat puzzled) that it came from Anthropic, but that's not the case. Here's a link with some background information: simonwillison.net/2025/Dec/26/...

In Germany the only source of electricity that keeps growing and growing: renewable energy.

Solar and wind keep expanding and even though nuclear is no more coal generation has already shrunk significantly and keeps falling.

What Problems Do AI Browsers Solve? | Software 7

I really wonder what problem AI browsers are supposed to solve. Perhaps it's simply about creating detailed user profiles to sell ads, how I came to this conclusion, see my blog post here: software7.com/blog/what-pr...

Claude Sonnet 4.5 behaved identically to 4.0 on my initial interactions, giving same incorrect answers to tricky UIKit/SwiftUI hit test questions and following the same flawed test case behavior, though with a really nice generated UI as always. Too early for conclusions, though. Let's see.

At first, I suspected an error in my code, in the request-response process, or in the feedback from tool calls to Anthropic. I then added a log and now know why my process is not continuing. The reason for this is HTTP status code 529, `overloaded_error`. OK.

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.

The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.
