Try googling (or whatever the term is for ChatGPT 🙂) for "Jupyter keyboard shortcuts". Notebook keyboard navigation is awesome and makes you very productive (inserting cells above and below, changing cell type between code and markdown, etc.)

The "TAB" key should do it.

Ok, the first version of the docs just got published at the link above.

Thanks! Yeah, we'll prioritize filling this gap in the docs. For now, look up the class called "Excel" and its static methods. E.g.:
// load all sheets
Map<String, DataFrame> data = Excel.load("my.xlsx");
// load a single sheet
DataFrame df = Excel.loadSheet("my.xlsx", "Sheet 1");

Very nice! I resisted the urge to make “$” a method name in DFLib for expression shortcuts, but here it looks very natural 🙂

That’s assuming human developers catch up with all the new stuff in each Java version 🙂

DevNexus is off to a great start! 🙂

Those are like Docker containers - you need a dedicated one for every process

Great, going to try it. Learned something new today 👍

Yeah smth like this. Not fully sure how Binder works, but I assume it would require Java kernel install somewhere behind the scenes

Being one of the Java kernel developers, I’d like to see better exposure of kernels for different language (well, Java in partcular 🙂) . Eg here jupyter.org/try#kernels and this won’t even require any noticeable dollar spending

I think all platforms turning into store fronts (a nicer term than "enshitification" but same phenomenon really) is a likelier reason than simply fragmentation.

Blockchain is just blockchain. But LLMs are so complex that nobody could say for sure they couldn't become AGI. So everyone fully committed out of FOMO. Nobody figure out AGI, corps got lefts with ML models they can't find any real use for, and investors really don't want to be left bagholding. 2/2

Pretty much, but if you are working in Java that has no culture of either REPL or notebooks, it is also a gateway drug to that style of programming

Are you still a programmer if you start counting indices from "1"? 😀

One reason I noticed why tech docs are not searchable is they are often long books published as a single HTML page. So Google doesn’t rank them well for specific topics. I am considering breaking mine into many pages to test the hypothesis
comment in response to

Yes, pretty much. Fundamentally, it is those 3 things:
1. API to control rendering of certain Java objects in a certain way that a notebook code or dependency can tap into
2. Fixed-width character rendering (DataFrame data and such)
3. HTML/CSS/JS rendering (charts)

Red Hat was acquired by IBM in 2019, so I guess it is just shuffling things around internally?
