I've recently submitted a paper to a conference requiring anonymous submission, meaning that the name of the authors should not be included, and no obvious self-reference should be made. The problem is that I add additional information relevant to the submission, such as some proofs and some code working on an example, calculating some numerical data (that could be found on the paper, but requiring some effort).
For a non anonymous submission, I would have published a technical report with all the proofs, cited the report in the submission, hosted the code on my website, and put a link to it. However, since the technical report would not have been anonymous and since my website is obviously linking to me, it was not possible.
Concerning the proofs, I managed to put them in the appendix, explaining that they were only intended for the reviewing process, but I could not find any solution for the code. The conference submission site (easychair) did not provide any way to input additional data. What's the best way to deal with this kind of situations?
If you need to distribute stuff anonymously via the web, as far as code goes, you could create a pseudonymous github or Google account for a "project," and then make it accessible during the review period. Once the review period is finished, you could delete the site, if intellectual property issues are a concern.
