Re: [sage-support] Using sagenb
I'm teaching a new cohort of students this year and was hoping to give them a quick SAGE tutorial. Our IT guys have not been able to setup a SAGE server in time so I was wondering how stable sagenb is. Is it realistic to run a 90 minute lab session (tops) with about 40 odd students each logged in to sagenb? AFAIK, sagenb would most probably (if not certainly) not support that many people -administrators of sagenb would of course be more knowledgeable. Actually, your situation is a recurring issue on this list and people are always advised to set up their own server. You can do a quick search in the archives for various tips. I personally had set up a server following these instructions within an hour: http://wiki.sagemath.org/SageServer Another approach: http://wiki.sagemath.org/DanDrake/JustEnoughSageServer Most important hardware concern is about RAM: A single instance of Sage worksheet seems to occupy ~90MB (version 4.7.1); so, assuming that each student work on his/her own worksheet, you would need about 5GB of RAM for 40 people. Also security may be another important concern, as you would likely want the server to be reachable.

Re: [sage-support] Re: using existing functions with vectors / lists / arrays
I have something like: y = x^2 I can evaluate it at one point: y(2) # 4 I'd like to evaluate it at a group of points: y( x ) # 2, 4, 9, 16, ... Can this just work like in IDL or MATLAB? How would one define x? What is the quickest syntax if it can't just be a variable? Perhaps: For purely numerical work a la Matlab, you may want to use numpy arrays (you will be using Python and not any Sage functionality): sage: import numpy sage: x = numpy.array([1, 2, 3, 4]) sage: def y(x): : return x*x : sage: y(x) array([ 1, 4, 9, 16]) -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
Re: [sage-support] Re: Sage Live CD (Alternativ based on Puppy Linux)
Hi, 2010/2/20 PKHG pkhgrag...@gmail.com I tried a download ... but got only 359 MB? Trying to burn, complained about not correct lenght. So the dowload is 'wrong' I suppose Maybe share it at another 'host'? Greetings Peter Alex link (http://aghitza.org/misc/SageLivePupv02.iso) worked fine. Hello Peter, Thank's to Harald Schilly SageLivev02.ios is now mirrowed at the official Download servers! Link: http://www.sagemath.org/download-livecd.html However, I would be very happy about feedback concerning: * Bugs * Localisation (it should be asked at first boot, but it might not) * Hardware requirements (Processor, Memory - positiv and negativ experiances) * any Benchmarks * Is there something missing (i.e. the jsmath-fonts .. ) and generally * suggestions and feedback Thank you very much for this nice project; now it will be easier to impress friends at the university about the capabilities of both SAGE and Linux. I would like to share a couple of observations (of course these may have to do only with Puppy itself): 1- Loading to RAM took quite a while although my machine can be considered to be new. Maybe user can be urged to be patient. 2- SAGE worked without any problems. (Also, seeing LyX installed was a nice surprise!) 3- I was not able to switch on touchpad clicking. 4- I was not able to connect to WEP secured wireless through none of the connection wizards (there were two different). It seemed to get IP number but no connection was actually established (I'm not an expert by the way!). 5- The screen was dim and I couldn't figure out how to make it brighter.

Re: [sage-support] Trouble Building Sage 4.2.1
It may be that SELinux is preventing necessary programs from running (correctly). If this is the case, and as far as I understood from previous posts, the most practical solution is to disable SELinux during installation (and maybe for running SAGE later on too; though there seems to be a work around for this).
