@SjoerdC.deVries The bot still tweets to]](twitter.com/StackMma/status/272515936215506944) #obscuretag when it would be more likely to get people over here if it had #mathematica it would catch the eye more people interested in Mathematica especially with version 9 coming about now
@asim Yes I think that's the most important thing to be added over the last few versions for me. It allows it to be used for serious numerical work in some cases when it otherwise couldn't
@Szabolcs OK. Mine is a GT 555M so I think that they are comparible with yours being a little stronger. Of course the nice thing about having a CUDA card is that you can try CUDALink and OPenCLLink :)
@ssch indeedy! What made it worse was that I was demonstrating Mathematica to someone who hadn't used it in years. 'Check out how easy it is to tap into the GPU' said I.......He wasn't impressed!
@WalkingRandomly fwiw, I think that that would be helpful. We would just leave the answers as they are, and start answering new questions with a preface of Version 8 or 9
I'm surprised that the spikey is the same! Perhaps this should better be looked at as 8.1 than 9.0? Maybe WRI is feeling the pressure from the competitors to bump up the version numbers more quickly than in the past.
Agreed, but it is not that easy to do and only recently have good enough GPUs been available to make it worthwhile for them to do this rather than let the users write their own code.
They also do not support 64-bit MinGW gcc, which I find a little annoying considering that it isn't hard to do.
@OleksandrR. I guess so. I'm one of the support-guys on a nice HPC cluster at Manchester University with a set of reasonably good GPUs (C2050s, C02070s). People are doing lots of GPU stuff there in MATLAB for instance. Would have been nice to get them doing more using Mathematica
I had a devil of a time getting those infernel CUDA paclets working on our HPC cluster but that's another story
changing the subject completely...there is a little '805' just under my chat icon on here. What does that refer to? My rep here isn't that high
The chat isn't associated to Mathematica.SE but is a separate SE site in itself.
Anyway, your users are lucky to have such support. I get the strong impression that nobody here really cares about providing IT support that goes beyond installing software and perhaps fixing certain problems if they are not too hard and the people responsible can be bothered to do it.
@OleksandrR. Well I am lucky to be in a Uni that values such work :) I get to play with all sorts of fun stuff and get paid for it too. Where do you work?
I think I had better not say, although I am in the UK. I'm just a PhD student currently (but will have submitted by Friday and become a postdoc on Monday).
lol. And I understand why you want to keep quiet about complaining about uni IT support in a public form..However, if you are at Manchester, feel free to email me and let me know what's bugging you. I can't promise I can fix but I'll certainly have a crack
@acl it's not lack of support personnel so much as people who are very difficult to work with. Also I am pretty sure they all hate me since I repeatedly tell them how incompetent they are.
Support at Manchester includes training in packages such as MATLAB, Mathematica etc, code review and optimisation, installation problems, free high throughput computing for all postgrads+researchers
Just writing the conclusions to my thesis now. Laser plasma is pretty amazing actually. Before I started this I would never have thought you could get 1.5 keV ions from just a few mJ of UV light out of a boring old standard nanosecond pulsed laser.
The process and time series material looks nice too. I'm not too familiar with that, but time series are much used in my job. I just got me a book on that and walking through it with MMA on the side sounds good.
@all quick silly question: I need to export some data from mathematica into maple (so that its easiest to read on the maple side of things) Any suggestions?
has anyone seen whether two axis plots will be done "out of the box" like every other software can do. I found the "How To" (write your own code) still in the V9 docs.
will need to test this but maybe it offers a way of scraping sites that require login without using wget (which is easy enough to use it must be said): reference.wolfram.com/mathematica/ref$HTTPCookies.html
@SjoerdC.deVries saw it. But it seems that rotating a 3d is still old fashioned (from what I got from the docs). That is, no way of interactively choosing the pivot point
@BrettChampion what would the internal rationale be in having a software that does all sorts of esoteric plotting but can't do stuff that most people do day in, day out, and can do in pretty much every other software package.
@BrettChampion Image Assistant and other predictive interface look very interesting, but I was very disapointed with the lack of drag and drop (block diagram) and spreadsheet (multi cell or super cell) kind of stuff :-(
Do I need to input Quantity[8, "Meters"] or is there a cleaner way of writing it in the input cell? From the videos I saw examples of the user going to the wolframalpha equal sign to get the units... well, I simply have to wait for tomorrow...
@MikeHoneychurch while it's cool, was there a pressing need for gauges? In other words, why did this take priority over other features? I know, only WRI can answer that (and they won't), but I guess it had to be asked...
@rm-rf I agree it seems a bit trivial, but WRI must have junior staff in addition to the Daniel Lichtblaus, John Fultzes, and Adam Strzebonskis... given that they are producing a major release it's highly likely that everyone will be doing whatever represents the greatest contribution they can make, and the juniors have to do something productive, don't they!
@rm-rf in terms of what users need, just from users I know and from here and Mathgroup, I agree it would be a low priority.
@rm-rf features essentially reflect what developers think might be "cool" not what users are demanding. -- the 20 year absence of 2 axis plots being exhibit #1 to substantiate that.
I would like to know who wrote the general linear algebra stuff. As well as being probably the most significant aspect of this release its documentation is written in a very straightforward way and not the quasi-patronizing or handwaving fashion of some other areas.
