Cobol is in fact very easy to learn.. it is English like language. The problem is that banks and financial systems don't want to move out of cobol because it is very high performance language. To process batch of 1 million records cobol would take second where java will keep running for hours.
Another thing is that there are millions of lines of code written is cobol and converting them to another programming Language will be very costly and no one wants to spend money on things which are working without issue for many many years ...
Why the f do you think languages like Go, Rust, C and C++ exist??
What's the purpose of LLVM's optimisation on all of these?
+ IBM's "big iron" is a COMPUTER, just like any computer. write software which emphasize thinking how computer works...
Not cobol, python and this whole clean code bullsh*t, computers don't work in plain English, and without thinking about memory... It's trivial to find memory leaks
Love the content, just the title is confusing. Can you change it to something like “No one knows this code anymore”? Or like “The world runs on code no one knows anymore”
COBOL is easy , its not like we couldnt learn it , the hard part is learning how businesses implemented it
True, but also it depends how you feel about procedural coding paradigm.
Excellent share. Great thanks
I think the only way to migrate those code bases would be with TDD, only real way to know it is performing the same way.
Nothing better than COBOL and LISP :D
its true i was working on john deere legacy project and its very brainstorming and worst work to convert cobol , ibm db2 mainframe job to nodejs one.
I just think the same Can we really trust AI to convert codebase
Currently I am migrating PHP codebase to NodeJS and I have tried chatgt but it sucks 50% of the time but it works on straightforward things like reading file from disk or converting basic PHP class to js one.
right now generative ai is a declarative programming language, you don't have to tell every single step to it like you are writting every line of code but you can't tell it high level orders to complete on its own, need to give it particular steps to do, very small tasks to reduce your work, it's a companion who knows how to code but has no experience.
In future AI will get much better though, might build complete solutions from simple orders.
That article is most likely written by an AI by marketing team at IBM.
