I wanted to build a privacy-first RAG app. The kind where your documents never leave the browser. It means no API keys, no server, no third-party vector database watching what you search for.
The architecture was obvious: embed documents client-side with something like Transformers.js, store the vectors locally, and search them with cosine similarity. Simple enough. Except ...
I've been running K8s troubleshooting workshops for two years. We have a 200-student program at IT Defined where we throw broken clusters at people. Patterns emerged.
Most failures aren't novel. The same 25-30 failure modes account for 90% of real-world K8s incidents. If you can confidently debug these, you'll handle most production incidents.
Some bugs announce themselves loudly. A null pointer in a hot path, a missing route that returns 404 to every request — the kind of thing that fails immediately and points straight at the cause. Others are quieter. They let most of the stack work correctly and only reveal themselves at the intersection of two independently correct but mutually incompatible assumptions. The azurerm_storage...
Welcome to our weekly digest, where we unpack the latest in account and chain abstraction, and the broader infrastructure shaping Ethereum.
This week: Ethereum’s native account abstraction effort shifts into a structured multi-proposal phase, new research explores parallel zkEVM execution and higher throughput models, and Etherspot brings seamless gasless UX to Telegram...
Compound interest is one of those concepts I had nodded along to since high school without really feeling. The formula made sense on paper, the wikipedia chart looked impressive, and yet whenever a friend asked me "so what does 6% over 30 years actually look like?" I had to wave my hands.
This weekend I sat down and wrote it out as code. That single exercise did more for my intuition th...
