Joint Mathematics Meetings, January 10-13
The UTMOST team presented a poster on this project at the NSF
UTMOST poster session.
William Stein gave a one-hour Guest Lecture to the SIGMAA on Mathematics
Instruction Using the Web on the SaqgeMathCloud. Tom Judson was an
organizer of the "Poster Plus 5" Session on Open Source
Resources in Mathematics, which included a presentation by Tom Judson,
Rob Beezer and David Farmer.
The Sage project also had a successful booth in the exhibit hall, which introduced
many people to both the SageMathCloud and the Sage Cell Server.

Sage Education Days, June 16--18
`Sage Edu Days 6 <http://wiki.sagemath.org/education6>`__ will be
held June 16--18 at the University of Washington in Seattle. See
the website for schedule and videos of talks.
Anyone with an interest in the use of Sage in educational settings
is welcome to attend. The focus will primarily be on undergraduate
mathematics, but will not be limited to just that area.
There will also be a `developer conference
<http://wiki.sagemath.org/days58>`__ happening that whole week.

Sage Cell Server
In March 2014, the Sage Cell Server had an average of 1986
computations per day, about 100 more computations per day than in
February 2014. The service was visited by users in 158 countries
(about half coming from United States, 25% from Europe, and
10% from Asia). The top city accessing the service was Tacoma, WA
(no doubt due to Rob Beezer's online linear algebra textbook using
it), followed by Omaha, NE, Ottawa, Hartford, CN, and Fargo, ND.
SageMathCloud
In March 2014, about 40,000 projects were modified. At the end of
March, there were around 28,500 accounts (with about 150 accounts being
created each day) and around 43,500 total projects. See `this page
<http://boxen.math.washington.edu/home/schilly/salvus/stats/stats.html>`__
for more graphs and statistics.

UTMOST poster session
Several UTMOST collaborators talked in sessions, including the
MAA Open Textbook session (Tom Judson/Rob Beezer) and in the MAA
Online Resources session (Jason Grout).
The Sage project also had a successful booth in the exhibit hall, which introduced
many people to both the SageMathCloud and the Sage Cell Server.

Joint Meetings
We had a booth in the TUES poster session, and the Sage booth in the
conference hall was a big hit as well.

Mathfest
We had a very successful booth that we shared with the `Webwork <http://webwork.maa.org/>`__ folks.
AIM Open Textbook Initiative
American Institute of Mathematics has launched its `Open Textbook
Initiative <http://aimath.org/textbooks/>`__. This initiative will
review and provide links to high-quality open-source textbooks.
This initiative is supported in part by UTMOST.
Sage-Enhanced Textbooks
Rob Beezer `announced
<http://groups.google.com/group/sage-devel/browse_thread/thread/6b439a44b0794dbb/7f89285396f36b18>`__
his work on enhancing his `linear algebra textbook
<http://linear.ups.edu/sage-fcla.html>`__ and also `announced <http://groups.google.com/group/sage-edu/browse_thread/thread/39a89604d56ae837/2a1fe3b7265b38c6>`__
his work on enhancing Judson's `abstract algebra textbook <http://abstract.ups.edu/sage-aata.html>`__. Both
of these projects involved work sponsored by UTMOST.
Embedding Sage in a webpage (beta)
You can now embed Sage into any webpage! A beta version of the
Sage Cell server was released. See the `documentation
<http://sage.math.washington.edu/home/jason/sagecell/embedding.html>`__
for embedding a computation.
As an example, click the button below to explore a Taylor
polynomial
