Thanks to Andrzej and John for the clarification. I thought a lot
about this before emailing sage-devel, yet still didn't realize it was
"y(3)" that caused the problem. Thanks for the help.

Hi,
isn't this comming from y(3)? Using either
sol1.subs({y(x=3):4})
or
y(x)= function('y')(x)
makes the warning disappear. Nonetheless I also got lot of questions
from students about this warning.
Regards,
Andrzej.

Hi,
Somebody doing differential equations sent me this code, which you can
run in a fresh sage-6.9 session:
var('x,y')
y= function('y')(x)
eqn = diff(x^2+y^2==25,x)
sol0 = solve(eqn, diff(y,x))
sol1 = sol0[0].subs({x:3})
sol1.subs({y(3):4})
The *last line* outputs:
D[0](y)(3) == (-3/4)

Hi Harald,
I don’t see anywhere for mentors to sign up, but I will make myself available
again this year.
Cheers,

Nonetheless, there wasn't a "backup" Fields Medalist so, at least in

Hi, just a quick note to everyone: SageMath has yet again been
accepted as a mentoring organization for this years GSoC
More info on their new website here:

Next step: everyone who is interested to be a mentor, or at least help
us dealing with applications, etc

Yes, I certainly understand the residue field behavior, but the Zmod
behavior seemed weird. It is clearly not checking primality, but there does
seem to be some kind of size limit that affects what happens. I couldn't
find where this is in the code. For my situations I'd typically be willing

I'm pretty sure that they are actual slow
Just to point out the obvious, the error is almost at 2^32 so it is a
problem with large file support.

I was exploring some quotient ring operations and came across the following:
{{{
R.=QQ[]
K.=NumberField(y^3 + 2*y - 2401)
k.=K.quo(K.prime_factors(7)[1])

Concerning benchmarking, let me state that timing the tests is the easy
part. The hard part is doing something useful with the results.
For SageMath, the "doing something useful" part should be to make this
part of the continuous integration tests such that patches which

Ok, I'll try to send new letter on the same address.
Thank you for quick response!

Hi, so far, we do not even know if SageMath will be selected as an
organization for GSoC. You can make yourself familiar with SageMath, of
course, but for further activities I propose to wait until we know more.
I don't know why you didn't get an answer, maybe your email got lost
somewhere, so
Hello! I would like to participate in CSoC this year and I need sage-trac
account to try to make a small contribution to sage-project.
Few days ago I've sent a letter with inquiry on
sage-trac-acco...@googlegroups.com, but there is still no response. What
should I do?
Best regards,

That definitely should work.
See #20136 (I have no time to fix these issues, but that ticket should
contain enough information but somebody to fix it).
