"solved" is a very generous adjective

Thank you! If you had tried to use it before, it probably would have broken pretty quickly. Now it will still break, but not so quickly as to not be useful, hopefully. External contributions are mostly blocked on me right now to improve bot

For this project, Python is a hard requirement, though it's possible the approach may be applied (after significant effort -- Python took me ~3 years and counting) to other languages / runtimes as well.

IPyflow takes a round trip from client to kernel for each execution (including reactive executions) -- this approach is necessary to get the best possible accuracy when determining dataflow in a highly dynamic language like Python, but it i

It's very new, and the current frontend implementations for Jupyter and JupyterLab include some workarounds for fundamental protocol-level limitations that probably make adding this kind of feature as part of the core package a no-go (

Yep that was one of the talks that motivated this work -- talked about it in my JupyterCon talk today :) https://t.ly/78rS

For this particular project, Python is a requirement. For the general approach, the answer is more complicated. It depends on what hooks the language implementation exposes -- and even if it exposes enough to make this work in theory, track

Thank you for all the feedback, positive and constructive! Yep docs definitely need a lot of polish :) 3. I actually started from scratch -- ipyflow's reactivity model is a bit different from these, since for Python, my experience is t

It's running on top of vanilla CPython, but with heavy instrumentation via sys.settrace as well as ast transformations. x and y are just normal Python ints. The downside is the overhead, but it's paid mainly for top-level / m

Yep. I think there is also a way to enable it by default in your ipython profile which I'll document at some point, so that you don't have to run `%flow mode reactive`. I'm curious though -- personally I much prefer to use th

Hi -- author here. I just presented this work at JupyterCon 2023 so I figured it was time to advertise more broadly. There are a few rough edges but my hope is that, by making all the reactive behavior opt-in and only enabled for in-order e

I think this depends. Universities seem to have the power to generate "tuition waivers" that accompany TA positions and a few external fellowships such as NSF GRFP, but if you're funded solely from one or more of your advisor

I probably should have phrased it differently. I think the attitude in China is that, if somehow forced to choose between individual liberties and economic prosperity, many will choose the latter -- because they see it as enabling the forme
