Tactical tornado is such a good metaphor for LLM delegation. I've definitely felt myself getting detached from the code, too tactical😅
On the flip side, I can also iterate on design so much faster and try out different strategies.
LLMs shift where the friction should be.

The ultimate LLM coding agent benchmark: upgrading DataFusion in a project without crying🤪
Do this:
```sh
export SDKMAN_DIR="$HOME/.sdkman"
# Lazy load SDKMAN
_load_sdkman() {
[[ -s "$HOME/.sdkman/bin/sdkman-init.sh" ]] && source "$HOME/.sdkman/bin/sdkman-init.sh"
}
# Create sdk wrapper that loads on first use
sdk() {
unset -f sdk
_load_sdkman
sdk "$@"
}
```
Finally optimized my zshrc with Claude Code after years of procrastination😅 Reduced startup time from 1.2s to 0.1s!
The trick is lazy loading.
Instead of:
```sh
export SDKMAN_DIR="$HOME/.sdkman"
[[ -s "$HOME/.sdkman/bin/sdkman-init.sh" ]] && source "$HOME/.sdkman/bin/sdkman-init.sh"
```
The kube-rs testing docs are great! Packed with details you can borrow for k8s related projects.

spent a full day troubleshooting rust CI 🫠
Lesson Learned
- always use `--locked` flag to get reproducible build [1]
- leaky tests [2] could happen with testcontainers. use RAII pattern to exit
- LLM is good at adding debugging logs with emoji 😜
Yet another day being impressed by datafusion's extension design :)
> Extensions can be used to attach extra data to the session config – e.g. tracing information or caches. Extensions are opaque and the types are unknown to DataFusion itself, which makes them extremely flexible.
Great DuckLake demo using Marimo notebook. Having the metadata layer as a standard SQL database is a quality of life improvement❤️

TIL, many data systems support wasm UDF. Server side wasm is very interesting. dylibso.com/blog/wasm-udf/
Just read OpenAI's Dec 11 outage postmortem [1] -- perfect example of k8s control plane metastability:) Great pairing with Marc Brooker's reinvent talk [2].

Exciting roadmap item from Fluss:
> Fluss will support the Kafka network protocol to enable users to use Fluss as a drop-in replacement for Kafka.
Long lives Kafka!
