Is there a complete open source implementation of Risch's Algorithm?

Dihydrogen monoxide

https://spectrum.ieee.org/ is also good.

I like TechXplore.

Anyway, in most cloud services you can allocate a maximum budget each month, so you don't risk spending more that you want.

I have a debit card (VISA) and they accept it. Previously Google did not accept it, only credit cards. I don't know about prepaid but I think the reason you want to use one is why they don't accept them.

Nightmarish!

Sadly there is a lot to improve to be useful. I had horrible results with the searches.

https://github.com/bramstein/typeset This is an implementation of the line breaking algorithm used in TeX in Javascript.

I like writing in a Jupyter notebook. You can use Markdown, write equations with Python and use a module like SymPy to transform to LaTeX, create graphs, etc.

If scientists continue tolerating the monopolies of big editorials, this situation is not going to change. It is time to embrace open access journals. Meanwhile, I use SciHub.
