I had a candidate do a very simple linked list question (find and remove a node) entirely via C++ template metaprogramming. We made an offer but he turned us down saying the work would be too boring

For non programmers, SQL (structured query language) is usually used to get data in and out of tables. Few people know it can be used as a full feature programming language and have the skill to do it. It's like asking someone to take a picture and they draw a photorealistic one in pencil.

Using strace to troubleshoot #MySQL performance issues can be highly effective, especially for diagnosing low-level system calls and pinpointing issues like excessive I/O, network delays, and file access bottlenecks. strace captures and logs system calls made by a process, which helps you understand MySQL's interactions with the operating system. #MySQLPerformance @MinervaDB #dba zurl.co/6jaj

It took 10+ years to map the 302 neurons in a roundworm's brain by tracing the wiring by hand. Our #AI algorithms, coupled with TensorStore have enabled us to reconstruct bigger brains of more complex creatures. More on the latest research → youtube.com/watch?v=VSG3_Jvn…
