A person could be an author or a co-author of maximum of 3 papers.
As of year 2018 the Association for Computing Machinery requires that all proceedings published by it have the same layout.
Thus all accepted papers should be composed and formatted by using the new ACM's article templates
(https://www.acm.org/publications/proceedings-template). If you want you can still submit your papers in our old format,
but if they are accepted you should prepare the camera-ready version by using the new ACM template.
Traditionally all CompSysTech papers should be in English and up to 8 pages long.
