In an earlier post, I lamented<\/a> the modern difficulties in running old instances of Jmol, an example of an application program written in the Java programming language. When I wrote that, I had quite forgotten a treasure trove of links to old Java that I had collected in 1996-7 and then abandoned. Here I browse through a few of the things I found.<\/p>\n

The collection is at DOI:\u00a010.14469\/hpc\/2657<\/a>. Here I track down how some of them are doing 20+ years on.<\/p>\n

    \n
  1. Formula-To-Mass-To-Formula (f2m2f<\/a>), which was started in August 1996 and was written by\u00a0Guillaume Cottenceau, a french undergraduate student visiting London and who wanted to learn to program. I suggested he try Java, and as I recollect sent him out to the business park west of London where Sun Microsystems had an office to learn how to do so (they had only released the development kit a few months earlier!). The applet he wrote still works (being unsigned, you have to jump through a few hoops to allow it to run (but be quick, not many browsers will still let you do so!). \"\"The applet also has a benchmark feature. Running the heavy bench now takes ~ 0.4s on a laptop. \u00a0I cannot be sure, \u00a0but I seem to remember that this one took ~20 seconds back in 1997.\u00a0<\/li>\n
  2. Guillaume\u00a0then returned to Paris to finish the above off, but also managed to find the time a year later to produce Jspec, a visualiser for NMR and MS. Darek Bogdal was visiting from Poland in August 1997(8?) and he incorporated these tools into a general spectral display and problem solving resource<\/a>, which also still mostly works (with no curation!). The bit that does not work depended on the Chime plugin, now long gone and of course replaced in large measure by Jmol and now JSmol.\u00a0\"\"<\/li>\n
  3. Here is<\/a> an equation setter. The original site has long gone, but I had copied the classes over and it also (mostly) works!\"\"<\/li>\n
  4. This dates from 1997<\/a>\u00a0by Wyn Locke and Alan Tongue and uses JavaScript plus the spectral viewer to communicate with Chime. All done much better by many others since of course.\"\"<\/li>\n<\/ol>\n

    That said, many of the other links at\u00a0DOI:\u00a010.14469\/hpc\/2657<\/a> no longer work. In truth I am slightly surprised a few still do!\u00a0<\/p>\n

    Quite possibly these screen shots may be the only visual images that can be created in the very near future, as all but very specialised web browsers drop “plug-in” (aka Java) support. So perhaps it will be RIP Java, at least for the in-browser frame mode (but certainly not for the stand-alone application mode).<\/p>\n\n<\/div> ","protected":false},"excerpt":{"rendered":"
