[sage-devel] Sage notebook and safari
Hi, all, This is to complete an earlier discussion. I filed a bug with Apple regarding the failure of tab-completion with Safari 3.1. I think Tom has figured a way of dealing with this, but here is Apple's reply: We no longer send keypress for tab keys. That's likely the cause of this issue. Whatever you are doing in their[sic] keypress handler to do text completion should be done in the keydown handler. Please try that and let us know if that resolves the issue. Justin -- Justin C.

[sage-devel] Re: Status of Sage 3.0.a5 with gcc 4.3/Arch Linux
Ok. 3.0.alpha6 with gcc 4.3 is down to the following doctest failure: sage -t devel/sage/sage/rings/real_double.pyx ** File /home/mabshoff/sage-3.0.alpha5/tmp/real_double.py, line 544: sage: a = -RDF(1)/RDF(0); a.str() Expected: '-inf' Got: 'inf' ** File /home/mabshoff/sage-3.0.alpha5/tmp/real_double.py, line 979: sage: a.is_positive_infinity() Expected: False Got: True ** File /home/mabshoff/sage-3.0.alpha5/tmp/real_double.py, line 991: sage: a.is_negative_infinity() Expected: True Got: False ** This is caused by GSL relying on the system's isinf() function which is either buggy or did change behaviours, i.e. isinf(-1/0) is supposed to be -inf, while on OSX 10.5 with GSL 1.10 that case returns inf. I did discuss this with Justin Walker at SD7, but then I never followed up whether this is the correct behavior or not. Interestingly enough GSL's isinf() function [that is used as a fallback in case the system doesn't provide it] returns -inf for isinf(-1/0). The patch is simple enough by fixing GSL. Thoughts?

[sage-devel] Fwd: One Laptop Per Child Is very interested in Sage
Hi, Is there anybody at UW that is interested in meeting with some OLPC people? (I'm cc'ing this to sage-devel, because people there are generally interested in OLPC.) -- Forwarded message -- From: Seth Woodworth [EMAIL PROTECTED] Date: Thu, Apr 17, 2008 at 3:40 PM Subject: One Laptop Per Child Is very interested in Sage To: [EMAIL PROTECTED] Hello, I'm an intern at OLPC and I'm throwing an event at UW this weekend. While the event is specifically about healthcare, there will be several people there that are strongly involved in OLPC. For some time SAGE has been kicked around as a back end for a graphic calculator application on the XO laptop, and there are many developers that would love to pick your brain on the subject. Since there will be several OLPC people at the UW this weekend, I was wondering if you would be interested in meeting up with us and discussing SAGE. This invitation of course applies to any of the other SAGE team members as well. The XO laptop is a great piece of machinery.

[sage-devel] Re: One Laptop Per Child Is very interested in Sage
Yes, I'm definitely interested. Please forward the meeting details when you've got them. I think the goals of the OLPC align quite well with some of the goals of Sage. You should probably also include the sage-edu folks who are probably going to be even more interested in this.

I'm actively working with Luanne Burns on a version of her PhD thesis http://digitalcommons.libraries.columbia.edu/dissertations/AAI9333735/ called MEADOW: An integrated system for intelligent tutoring of subtraction concepts and procedures. Basically what happens is that the student does subtraction homework problems and this software monitors the students actions (using a combination neural net and rule based programming). If the student makes a mistake the system analyzes the mistake and explains the mistake (using pictures, scripts, audio, etc) to the student. Thus it acts as a constant tutor to the student in a home setting. Thus it is perfect for at home tutoring. We think that the 3rd world students will not have timely access to tutors and the parents may not have the necessary expertise to handle arithmetic. This is math in some sense but quite far away on the spectrum from doing Sage on an XO :-). It is probably best to have any further discussions off the Sage lists.
