I started burning down the backlog of all the stuff I wanted to get to for side projects but never had time for (before LLMs):
- https://smacke.net/ffsubsync -- automagically synchronize subtitles, now purely client-side in your browser thanks to pyodide
- https://ipyflow.github.io/ipyflow/lab/index.html?path=demo.i... -- reactive python jupyter notebooks, again in the browser thanks to pyodide / jupyterlite
- https://smacke.net/pipescript/lab/index.html?path=demo.ipynb -- magritter-like pipe / placeholder syntax for ipython / jupyter, again able to run purely in the browser
- https://smacke.net/pycograd/lab/index.html?path=pycograd_sim... -- pyccolo and pipescript-powered autograd, once again able to run purely in the browser since numpy has a wasm target (notice a theme here :) )

Some auto formatting italicized the text between * on different lines :')
Should be `reduce[$*$]`

Hi HN, I built pipescript over the holidays after I discovered magrittr for R and realized the same kind of pipe operator and placeholder syntax could be implemented for Python notebooks with a bit of creativity. I developed it while using it in parallel for Advent of Code and had a lot of fun with it; hope you like it.

Pickling + unpickling the object is a neat trick to update objects to point to the new methods, but it's even more straightforward to just patch `obj.__class__ = reloaded_module.NewClass`. This is what ipython's autoreload extension used to do (and still does in some circumstances, along with other tricks to patch up old references), though nowadays it's had some improvements over this approach: https://github.com/ipython/ipython/pull/14500

I developed a tool (https://github.com/smacke/ffsubsync) which can sync subtitles against each other (or even against an audio track), and this can be used in conjunction with other tools such as https://pypi.org/project/srt/ to combine multiple subtitle streams into a single stream. I've used this strategy to good effect to get both English and Chinese subtitles up at once.

Discussion on reddit from when I posted about this (more than 10 years ago now!): https://old.reddit.com/r/math/comments/144qc4/a_beautiful_pr...

You're probably referring to nbgather (https://github.com/microsoft/gather), which shipped with VSCode for a while.
nbgather used static slicing to get all the code necessary to reconstruct some cell. I actually worked with Andrew Head (original nbgather author) and Shreya Shankar to implement something similar in ipyflow (but with dynamic slicing and a not-as-nice interface): https://github.com/ipyflow/ipyflow?tab=readme-ov-file#state-...
I have no doubt something like this will make its way into marimo's roadmap at some point :)

ipyflow has a %%memoize magic which looks quite similar to %%xetmemo (just without specifying the inputs / outputs explicitly): https://github.com/ipyflow/ipyflow/?tab=readme-ov-file#memoi...
Would be cool if we could come up with a standard that works across notebooks / libraries!

I'm a big fan of Marimo (and of Akshay and Myles in particular); it's great to finally see a viable competitor to Jupyter as it can only mean good things for the ecosystem of scientific tooling as a whole.
