I assume uploading to arXiv doesn't count as having published a peer reviewed journal article, which is a problem for professionals.

For example, for me to progress in my current job I either need a doctorate or to have published a number of peer-reviewed articles in recognised journals as first author. I have written two IETF RFCs and these count for nothing.

I am not a scientist, I am a software developer. I am not employed as a scientist, I am employed as a software developer. But the rules of the organisation are thus.
