SageMath is one of the well designed approaches to blur the boundaries
among being a user, developer and contributor in the open-source
ecosystem. Probably I will be hanging around for a long time be it
bugging, complaining, documenting, adding content and eventually

From my point of view SageMath definitely has *not* failed! I would not be able to do the computations I need
for my research on any other platform at this point (of course this could be possibly done, but with an enormous
effort). More and more people are interested in switching to SageMath at least people with a focus in
combinatorics, representation theory, root systems, .... and are offering to organize SageMath Days to learn
and start using and contributing to SageMath. In fact, we just concluded SageMath Days in India and there were
people interested in a variety of topics. From this point of view, SageMath has gone far beyond any other
mathematical software system I know!

I'm working on modeling the efficacy of a hypothetical infectious vaccine (like the live
polio vaccine). I have lots of small coding chunks that makes the sage notebook great for
working through each section of the problem. SageMath including Sop and networkx has eliminated a
lot of the tedium I would have had to churn through otherwise, while native plotting allows
easy visualization.<br />
An earlier implementation in Mathematica 6.0 was orders of magnitude slower for a simpler
simulation. While neither implementation was optimized, my first pass in Python/SageMath was much
more effective, and easier to write and understand.

SageMath brought me back to using linux, perhaps permanently this time.
I only use windows for games these days. I actually haven't used SageMath very much recently.
I'm doing stock trading strategies and I was using R. But every time I left R for a while and came back,
it seemed like i had to relearn it over again. SageMath helped me to see how much simpler just doing it in python is,
and I find that I only really need numpy and matplotlib with pyplot for what I'm doing,
mostly simple calculations on stock data. Although it's nice to know SageMath is there if I need it.

Take the elliptic curve E:y^2=x^3-34790720*x+78984748304. This elliptic curve has CM by the
ring of integer of the quadratic field Q(sqrt(-163)).<br />
Compute:
<ol>
<li>P(x) the 163-th division polynomial. Then we have that this polynomial is of degree
13284.</li>
<li>Factorization P(x): I expect that the factorization over Z[x] of P(x) is of the form
P(x)=g(x)*h(x) where deg(g)=81 and deg(h)=13203.</li>
<li>Then I should build the number field Q(z)=Q[x]/h(x).</li>
<li>Check if y^2=z^3-34790720*z+78984748304 over Q(z). Take y.</li>
<li>Build the number field Q(z,y) and check if it is Galois and/or Abelian.</li>

SAGE was able to factorize my polynomial and recognize if an element over a field of degree
81 was an square! It was something close to a miracle! And the best thing is that I obtained

The model I am reimplementing and extending was written in a dialect of BASIC, QuickBASIC I
think, in the late 80s and carefully backed up onto now-unreadable 5 1/4" floppies.
After playing around with writing the program in Scilab, I reviewed my methodology and
realised I wanted to have something that is more reproducible in the future with regards test
runs and results. NetCDF support is available with Python. Rather than building my own Python
development environment I remembered a colleague had talked about SageMath. The model need to
write as well as read NetCDF files, so I am building NetCDF and pycdf packages for SageMath.

In my opinion, SAGE's notebook is the real killer feature, which I don't recall to
have seen in any other (commercial or not) software. I mean, this is the only scientific
program that I've found, allowing such an easy collaborative job within local networks,
something that is not comparable to any kind of subversioning software or stuff like that.
The only idea that I can access my data from abroad (if needed) by setting up a SAGE server
makes me happy. Moreover, the nice interface is valuable as well, like the presentation of
results in latex format.<br />
I know that interfaces are not really scientists' job, but having a good one is a real
step ahead. And plot interactivity is a one million dollar feature for people who deal with
design and system performance evaluation.

The fact it is an open-source alternative to Mathematica. I work as an engineering contractor

annoying Mathematica charges even more in the UK than in the USA (about 50% more), does not

I like the freedom to experiment and the flexibility to use the right tool for what I want to
do. I also love the notebook interface, it makes writing self documenting code easy and
allows me to communicate what I am doing to other people.

The fact that SageMath is open source make it transparent to see how the calculations were made.
The commercial systems are like a black box, not knowing exactly how the calculations were
made is just not acceptable when you are doing research.

In teaching:<br />
I used SAGE for some sections of a differential equations course I was teaching last fall.
Wasn't sure if the students would just "take the hit" and refuse to learn SAGE
so I made the assignments worth very little and very easy. Also, I made extra assignments for
extra credit.<br />
It turned out not only did most do the assignment but a lot more than I expected did the
extra credit ones too and say that they liked SAGE and its philosophy.<br />
I would call it a success in teaching.<br />
<br />
In research:<br />
I wrote some time ago a procedure for computing Duursma zeta functions of a linear
error-correcting code. AFAIK, no other program does this (not GUAVA nor MAGMA, ...). These
zeta functions are very similar to the zeta function of a curve (they have a functional
equation, a "Riemann hypothesis", etc), except that no one knows why the
"Riemann hypothesis" doesn't always hold. There is a conjecture that it holds
for a certain "extremal" class of codes, so maybe the RH holds for "good"
or "optimal" codes (since optimal codes are sometimes extremal)?<br />
A year or 2 ago, I found an example of a formally self-dual with optimal parameters which
violates the RH.<br />
I would call that a success in research.

Why SageMath is useful for me.<br />
<br />
I have a program that I do for my master thesis, it's some finite elements method +
electronic structure calculations [on] some very fast Solaris boxes. I just remember I gave
up installing scipy+umfpack on some old Debian boxes in Munich, so I just installed SageMath
instead. — [If one] of the aims of SageMath is to be a viable alternative to Matlab, so
that's about it.<br />
SageMath Solaris port +1!<br />
<br />
[Maybe] I'll be teaching some undergrad calculus stuff in a year or two and so I was
thinking which programs I'd use and the constraint will probably be Windows.<br />
Installing python+sympy in Windows is not convenient — it's about 10 clicks with mouse
and it installs somewhere to C:\Python2.5 by default and I don't understand Windows much
but I just get the feeling that it messes up with the registry as well and I don't like
this at all.<br />
So, SageMath Windows port +1 as well!

You guys are awesome, I ported my code to SageMath in maybe a week, and added multi-processing
today. Now I'm working all 8 cores, using a real programming language, and getting
super-high-precision calculations... incredible!

Project:<br />
Computation of cohomology rings of finite p-groups with coefficients in GF(p)<br />
How SageMath and its components were used:
<ul>
<li>I use Gap to compute certain elementary abelian subgroups.</li>
<li>Due to Cython, i can use C-programs of David Green for computing minimal
resolutions.</li>
<li>Cython is a very nice python-like programming language, in which I created classes for
cochains, chain maps, cohomology rings etc.</li>
<li>In order to find a minimal generating set and a minimal set of relations for a
cohomology ring, i need Gröbner Basis computations in graded commutative rings (or simply
"commutative", in characteristic 2); Singular does that job.</li>
</ul>Success story:
<ul>
<li>The Z/2 cohomology rings of all 267 groups of order 64 were known before, but with other
software required a computation time of several days. Our programs based on SageMath only need
45 minutes on a 2.3 GHz CPU.</li>
<li>Previously, the computation of the Z/2 cohomology rings of the 2328 groups of order 128
was out of reach. With our programs, a complete computation was possible. It took about two
months of computation time on 4 CPUs with 2 GHz.</li>
<li>We present our results (also including all but 9 groups of order 243 and one group of
order 1024) <a href="http://users.minet.uni-jena.de/~king/cohomology/">here</a>.</li>
</ul>General and personal experience:
