a look at the integration of technology and people at the turn of the century. This session was an IBM internal session, written and presented at the IBM Academy of Technology at their Annual meeting in the year 2000. It contains NO confidential information.

It is included here as I'll refer to it in an upcoming blog post.

Java programming for the mainframe - Not just technology

  3. 3. © 1999 – Prepared by Mark Cathcart for the IBM Academy of Technology Annual General Meeting, 2000. Programming Landscape Year 2000 Older programmers go (back?) into retirement Non-Web programs vs. Web programs More than 1000x more Non-Web programs (ok, I made this up!) Business languages COBOL, PL/I etc. still pervasive C/C++ Never quite made it... (as business languages) Probably more lines of C than any other language It's all in operating systems, tools(compilers, make etc.) and technology (TCP/IP etc.) Specialized languages on the increase Pearl, Python, Rexx(NetRexx) (it appears)
  4. 4. © 1999 – Prepared by Mark Cathcart for the IBM Academy of Technology Annual General Meeting, 2000. Programming Landscape(2) What about Assembler/Machine code ? Still in use... Airlines, Banks, etc. High volume transaction systems but getting unacceptably expensive (to modify, maintain etc.) Increase in processor speeds continues More than ever we can afford machine inefficient languages Cost is "man" versus machine We are in the home straight... Enterprise Java is here! Open Source is coming... C# is late, offers little new and will lack a pervasive, open runtime

  8. 8. © 1999 – Prepared by Mark Cathcart for the IBM Academy of Technology Annual General Meeting, 2000. What can we do ? Invest in people Encourage Educate Integrate tools/compilers Provide Language Interoperability You tell me!
  9. 9. © 1999 – Prepared by Mark Cathcart for the IBM Academy of Technology Annual General Meeting, 2000. Here is one we wrote earlier! Any other ideas? Do you have anything to offer?
  10. 10. © 1999 – Prepared by Mark Cathcart for the IBM Academy of Technology Annual General Meeting, 2000. Mark Cathcart has left the building! Gone to teach 2x Java for OS/390 Programming Workshops at the IBM OS/390 Expo in Washington DC. PLEASE GET IN TOUCH VIA Lotus Notes mark cathcart/uk/ibm@ibmgb
