I always wished these notepad calculators would run plain python. POC - https://github.com/idanpa/jupad

For lightweight calculations re-execute everything while typing cells https://github.com/idanpa/jupad

On: Ask HN: What tool for live, collaborative, symbolic math?

[idanp]

lyx [1] is great for live editing of latex . Set the instant preview Tools>Preferences>Display>Instant Preview if you want automatic latex rendering, although the editor rendering is nice as it is.

For something that is more of a calculator, SymPy [2] with sympy.init_printing() would be rendering latex automatically in any Jupyter notebook.

Specific tools I created for my own use for leveraging the above is pypad [3] together with calcpy [4] (%load_ext calcpy)

[1] LyX https://www.lyx.org

[2] SymPy https://www.sympy.org

I use SymPy as my calculator with https://github.com/idanpa/calcpy

[Hugsun → idanp]

This looks perfect. I've found native sympy to be a little cumbersome to use.

[qorrect → Hugsun]

Same here, I've been slogging through with raw sympy this tool looks great.

How do I speed up the start time for it - any ideas? Recompile it with PyPy or similar?

[idanp → qorrect]

I think PyPy usually has slower startup time. Need to try to defer some of the imports to be done in the background, see how good is the outcome. Feel free to open an issue in github.

this project is AWESOME! cool idea man

On: Ask HN: Why are there no open source NVMe-native key value stores in 2023?

[idanp]

Virtualization can happen in the hardware itself, e.g. SR-IOV.

yes, with modifications - https://github.com/idanpa/calcpy

[poetaster → idanp]

Looks really nice! I wanted to ask if 'matplotlib' was strictly needed since it's a big depends?

[idanp → poetaster]

matplotlib is not needed, SymPy fallsback to ascii plotter and this is what I use on phone with termux.

On: SymPy makes math fun again

[idanp]

I felt SymPy needed some adjustments for it to be fun and useful for my day-to-day calculations, so I wrote this:
