I am not a lawyer this is not legal advice.
Search for copyright assignment agreements, there are a few good template documents. I’d request a signed document instead of simply stating it in the PR. In all cases I would recommend verifying the document and process by a lawyer before you start using it.
Also, I would consider not requiring copyright assignment if at all possible for the project in question.
A lot of fun so far ! Thanks for making this
If I understand your reply correctly (the output of free would be clearer), having 80% of RAM used as cache would indicate that it is used for caching files such as map and chunk data. This is normal in Linux, and the game would lag more without this feature. The link I shared explains it better than I can.
If you feel this is still not the case, you can share info such as free output, list of open files, etc, while the issue occurs.
There might be an actual issue in your case, but this feels to me like https://www.linuxatemyram.com/
I’m expecting mapping will write a lot of map data to files in your world folder which might explain the apparent high ram usage. Try looking at disk usage while the issue occur maybe ?
Open source Not […] allow […] commercial applications
For some definitions of open source, this is contradictory (FOSS). Some non FOSS licenses do limit commercial use while making the source available, this could be a possibility for you.
But, I’d instead recommend that you check if a copyleft license such as the GPL provide enough protections for your use case.
I don’t have the information regarding xmodmap, but here are two other options which I am using if you are interested.
I recommend https://github.com/kmonad/kmonad
First, thanks for working on Pharo, what an amazing environment.
I am not a lawyer so you should double check.
For GPL, indeed the image as a whole would be GPL. If the personal project is more of an “executable”, it might be what you are looking for, any further image modification would have to be released under the GPL as well.
If the project is more of a “library”, you might or might not prefer the LGPL. In this case I feel like https://www.gnu.org/licenses/lgpl-java.en.html would apply similarly to Java. As long as you can load the image and change the original library code, other code is not restricted on the license.
Next, they are going to ban importation of crowbars, because these tools can theoretically be used to pry open some car doors.
