epsilon

I've engaged in debates on HN about the definition of "open source" in the past, so there might be some disagreement about the meaning of the title. I've settled on using "OSI open source" to avoid this, since those discussions are uniformly tiring and unproductive. That said, I agree with parent: the repo specifically has a section regarding copyright and it simply says that all rights are reserved[0]. This is proprietary software, disallowing copying, distribution, and derivative works. It's weird, since even cloning the repo appears to be a violation of their stated terms, though they supply instructions for building the software yourself that of course requires copying the code to your machine first[1]. Copyright is weird. [0]: https://github.com/numworks/epsilon#copyright [1]: https://www.numworks.com/resources/engineering/software/b

They still are open source [1]. If I had to guess, the reason they locked the bootloader is the same reason they removed the symbolic math functionality (which is re-added in Omega [2]), test accreditation. They want to create a calculator to provide a good and viable alternative to TI. They can only do that if their calculator is allowed on tests like the ACT, SAT, etc. [1]: https://github.com/numworks/epsilon [2]: https://getomega.dev/
