• The best way to get the answer is not to ask questions, but to put the wrong answer. This is fun, but true indeed.

• Google’s NotebookLLM doesn’t support some kind of website, like this https://bbycroft.net/llm

• There is a tool for monitoring the browser via MPC named BrowserTools MCP. We can now debug the errors from the console directly from MCP clients (Claude desktop, Windsurf, etc).

• HTTP/2 allows multiplexing, multiple requests can be processed simultaneously in a SINGLE TCP connection. I forgot this.

• There is a technique to “log” asynchronously, I didn’t think about it before.

• There is a mechanism to “block” and “unblock” read operations while there is an active write operation. This is more important when we have more replicas. I learned this from Clickhouse database design. In a generic case, let's say we have n replicas, we use m for read operations and n - m for write operations. This is how we design architecture to object to the P99. When writing the data, there is a built-in “signal” to tell all the replicas that there is an active writing operation. Also when the write is finished, there is a built-in mechanism to synchronize data to all replicas. The hardware is crucial here, but that’s the high-level flow of how they can handle an enormous number of records with very high SLA. Also, the columnar database is crucial here.

• In software development, “greenfield” means starting from scratch, and “brownfield” means starting from an existing one.
