FW: Print Service Survey
by Vine, Harry A 15 Jul '16

Dear Colleagues, If you wish please complete the ICT survey for the central touch-card print service or feed back any observations to me which I shall forward on. Particularly consider our teaching lab printer provision. For your information on the cost element; collectively our teaching lab printers generate a modest profit for Physics. Kind regards Harry Harry Vine Email: h.vine(a)imperial.ac.uk<mailto:h.vine@imperial.ac.uk> Departmental Services Manager 216a Blackett Laboratory Department of Physics Tel: +44 (0)20 7594 7515 South Kensington Campus Fax: +44 (0)20 7594 1441 Imperial College London SW7 2AZ, UK Web : http://www.imperial.ac.uk/ From: Allanson, Chris Sent: 12 July 2016 17:35 To: Subject: Print Service Survey Dear All The College is working on improving the central touch-card print service and needs your input to identify the areas that are currently working well and those needing improvement. So far ICT has identified 3 main areas to focus on: 1 Reliability of central services and all printers 2 Account, credit and allowance administration 3 Supply chain for consumables Please could you tell us via this short questionnaire about your experiences with the print service, what works well and what other improvements are required: https://imperial.eu.qualtrics.com/SE/?SID=SV_cMv00edyeskgdet Alternatively you can tell us your views by emailing myself, Alex Yakimov<mailto:a.yakimov@imperial.ac.uk> or your Digital Partner. Thank you for your contribution to improving the print service at Imperial College. Kind regards Chris Business Analyst for ICT

Thanks Martin, This sounds very good. Please can I have a windows VM with the windows teaching environment and Anaconda installed for tests? I suspect that this will be a good solution looking at the Anaconda website.

Hi Will, Well it looks like we should go with anaconda, have both 2.7 and 3.5 installed but have 3.5 as the default. My vote for 2.7 was only because I have to deal with legacy stuff. I have cc'ed the physics computing list in case anybody else has any comments. Also I found a pge about the differences between the two and this can be found at: http://sebastianraschka.com/Articles/2014_python_2_3_key_diff.html Which be useful for those preparing teaching materials. Please don't update the system in Blackett until after the Global Summer School on the week of the 8th.
