Has anyone compared ClickHouse and StarRocks[0]? Join performance seems a lot better on StarRocks a few months ago but I'm not sure if that still holds true.

Didn't people already do that before, copy and pasting code off stack overflow? I don't like it either but this issue has always existed, but perhaps it is more common now

That's a ridiculous accusation. Swift is not an uncommon adjective.

CMU's Intro to Database Systems course is one of the best resources. Andy Pavlo has his lectures all up on youtube

> Sequoia buying UFC is really strange, too.

I'm having trouble finding sources for this. I do see that Sequoia Capital China invested in ONE Championship, but not Sequoia and UFC

There's key parts left out of that quote that changes the tone quite a bit. Here is the full one

"Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%." - Donald Knuth

This might not be a perfect example, but there's a paper by Michael Stonebraker "One size fits all": an idea whose time has come and gone

It might not specifically be DRY, but still related generic vs specialized code/systems.

> By mutable data do you mean - change data coming from OLTP databases?

Yes, exactly! I see there is some kind of support, but is it possible to use the OLTP database as an event source?

For example, say I had a table in my OLTP database, `data.returns`, that had columns `ts`, the event time, and `status`, which can be PENDING or COMPLETED. I'd like to generate point-in-time correct training data, where the feature is the count of completed returns. It seems like all the necessary information to calculate this is there

How does Chronon handle mutable data when backfilling? Or does it make some assumptions on the underlying data?

Unfortunately I haven't solved that issue either and the UI could easily break on updates

I also thought my usage pattern of ChatGPT resembled Jupyter notebooks. I tried to make a chrome extension[0] that adds a code interpreter to ChatGPT, but implemented it in the most naive way, with just pyodide.

I recently learned about Jupyter kernels and realized that was probably what I should've been using to build this out.

I named the extension JPT, combining Jupyter with GPT. I was very proud of myself for that one lol :)
