I sympathize with George’s thread – all of the little applets on my web site which still see
frequent use are - with exception of the Kernel estimator of Mattprob, where Chris used python libraries – server-side CGIs written in Fortran. There was no java etc. then and Mosaic was the hot browser…1992 or so Here is how it is done: http://www.ruppweb.org/Xray/comp/cgi_prog.htm One for the history books 😊 Cheers, BR From: CCP4 bulletin board <CCP4BB@JISCMAIL.AC.UK> On Behalf Of George Sheldrick Sent: Friday, June 8, 2018 09:23 To: CCP4BB@JISCMAIL.AC.UK Subject: Re: [ccp4bb] Python3 and MTZ This discussion has not convinced me to stop using Fortran. FORTRAN66 programs such as SHELX76 still compile and run unchanged with modern Fortran compilers, though I do use a few useful features introduced in FORTRAN77 and FORTRAN90 such as character handling and run-time memory allocation. The resulting executables also tend to be faster than when Python is used, even when it is used to call routines written in C++. George On 06.06.2018 20:54, Robbie Joosten wrote: Right you are Kay.

Just a note (for those whose operating system provides only one of the two Python flavours): RHEL7 has Python2 as system library, but Python3 can be installed in parallel (using "Software Collections"). The user makes a choice by setting the PATH variable. best, Kay On Wed, 6 Jun 2018 15:43:16 +0200, Nicolas FOOS <mailto:nicolas.f...@esrf.fr> <nicolas.f...@esrf.fr> wrote: >Dear Kay, > >depending of the motivation to develop in python3 (could be due to an OS >using python3 by default or you really prefer to work with python3).
