I submitted a paper to a conference, and got it accepted. While I was preparing for the camera-ready version of it, I made a mistake and an error slipped in.
After the firm deadline, I asked if a correction was possible, but they said it's too late since it had gone through all the procedures. So, it seems my conference paper will be uploaded online with an error, which is not too obvious, but obvious enough that a careful reader can spot it.
I'm writing a journal version of it, and making sure it doesn't contain any error. Would it be okay to have the journal version published error-free, while the conference version has an error?
Many say that no one actually carefully reads conference papers as they are mainly aimed to let others know new results, and say that it is journal papers that others read with more care if available.
This is my first published conference paper, and it is really embarrassing. I was obssessed with finding typos, and blind to technical errors.
