With principal funding from the National Science Foundation, we are organizing a Macaulay2 workshop, from Monday, January 6, 2014 through Friday, January 10, 2014 with Sunday, January 5 and Saturday, January 11 serving as the travel days. The workshop will be at the University of California, Berkeley, in Berkeley, CA. Activities will start first thing Monday morning (possibly Sunday night). The purpose of the workshop is to bring Macaulay2 developers together with those who would like to share or develop their skills at writing packages for Macaulay2 and those interested in developing the corresponding mathematical algorithms. Some sample software projects that might be undertaken are visible at http://www.math.uiuc.edu/Macaulay2/dev/projects/ although we are also looking for participants who might have new packages they are interested in. Further examples of possible projects are available as part of our past workshop topics, which can be viewed at: http://wiki.macaulay2.com/Macaulay2/index.php?title=WFU2012_-_Main_Page http://wiki.macaulay2.com/Macaulay2/index.php?title=IMA2011_-_Main_Page http://wiki.macaulay2.com/Macaulay2/index.php?title=G%C3%B6ttingen2011_-_Main_Page http://wiki.macaulay2.com/Macaulay2/index.php?title=CC2010_-Main_Page http://wiki.macaulay2.com/Macaulay2/index.php?title=MSRI2010_-_Main_Page http://wiki.macaulay2.com/Macaulay2/index.php?title=AIM2009_-_Main_Page http://wiki.macaulay2/Snowbird/ The new main Macaulay2 wiki page is at http://wiki.macaulay2.com/Macaulay2 and a project development page is in the process of being built there. Please take a look and consider posting your projects on that page. Attendance at this workshop by invitation only --- based on a brief application --- and all who are interested are encouraged to apply. We anticipate financial support for approximately 20-30 people with preference given to younger researchers. Also, please note that we expect to have such a workshop approximately once per year, so you should look for future announcements as well. If you would like to attend, please let us know as soon as possible. Everyone interested is strongly encouraged to apply, including graduate students and postdocs. Your application should include: 1. information about what algorithms you would like to work on, and what you have done in the past (this is the most important piece --- please put some thought into this and be as specific as possible), 2. a good estimate of travel expenses, and whether you would require financial support for housing and meals (when available), and if you will be willing to share a room. (Rooms may be in limited supply; if additional single rooms are available, and you want one, we may ask you to pay any additional cost). 3. your current institution and rank, and if you are a graduate student, your advisor's name. Applications are due by 11:59pm on Monday, September 30, 2013. We hope to allocate funds to participants by Friday, October 11, 2013. The application page is available here: https://docs.google.com/spreadsheet/viewform?formkey=dGRwZUdJWE9HZWdkdjBrMWpYVWhoVUE6MA#gid=0 A few other pieces of information you may need: 1. Please commit to being present for the entire workshop. 2. You will need to bring your laptop with Macaulay2 on it to the workshop. Sincerely, The Organizers Sonja Mapes, Frank Moore, and David Swinarski
