As early adopter of various Google hardware products let me tell you: Do not buy the Googlebook! If you do, you'll be beta testing an unfinished product which will be discontinued two years later

Before LLMs, I used to first check the utils folder when reviewing projects. It gave a good impression of the general code quality

But it's so much more fun working on the tooling instead! 😁 Actually, LLMs helped me so much with that. First, because tooling for me has become less and less relevant. Second because if there is need for a tool, a LLM can usually build that in no time.

In Summer '24 I bought a small server for our office using consumer components. Rock solid, can't complain going AMD Ryzen 9 7950X (16C), GIGABYTE B650M D3HP, 96 GB DDR5, 500W be quiet!, 2x1TB SSD, JetKVM

I'm kinda opposed towards codegen. A: because it was slow in the past B: It requires an extra manual step C: LLMs can just generate the entire thing, without the codegen step Better write docs how to do it manually, utilizing helper functions (from a package) and the LLM will do the rest.

Do you have examples which business logic can be shared between frontend and backend? I see a lot of things that can be shared, everything except for business logic 😅

Take your time once, and write helpful rules and articles for the AI to help it achieve the desired outcome. You'll learn justifying your personal preferences and refine your practices. Then point to those resources in the future. Those rules become the value of hiring you vs. any other developer.

Years ago, I created a riddle for my wife about her present. Unfortunately, it was to hard. Today, I gave the riddle to ChatGPT, Claude and Gemini. ChatGPT and Gemini got it right. Claude did not. My personal conclusion is that Claude, while very smart, doesn't know about local traditions

Yup, LLMs are great for reverse-engineering. It reads obfuscated code like humans read non-obfuscated code.

I wrote three MultiChildRenderObjectWidget in my Flutter career. Touching that layer is rare but it gives so much power. It's like building a Android CustomView back in the days. It helped us doing frame perfect animations/layouts without LayoutBuilder, which delays layouting by 1 frame

Isn't Claude perfect for estimating story points? I honestly think humans can't do it better. In the end, story points are a tool for PM/POs. They now have a tool to get unbiased estimates without interrupting developers. Perfect 👌
