Agreed. While not directly applicable, I was a huge fan of Mozilla's rr [0] in undergrad. Quoting their site: > rr records a group of Linux user-space processes and captures all inputs to those processes from the kernel, plus any no

With my database hat on, in the context of agentic systems I would argue that write-ahead logs form a good (and potentially transactional) interface between speculative agent work and durable world mutations [0]. That said, there are a _lot

It is an undergrad course, though it is cross-listed for masters students as well. At CMU, the prerequisites chain looks like this: 15-122 (intro imperative programming, zero background assumed, taken by first semester CS undergrads) ->

Pretty much. Plus, from my perspective - if a company is willing to screw over your advisor/professor, you know that they won't hesitate to screw you over too.

Thanks for the detailed response, looking forward to the VLDB paper when it happens! Your vision sounds cool. I wonder if you could get most of the way there by exposing the workload (across different pipeline stages) to a materialized view
