    I mostly use All as well. I have the following blocked:

    • all the meme communities that pop up. It’s just spammy posts

    • all beehaw communities. Mostly because they were defederated with the largest lemmy communities, and I didn’t want to talk to only a small subset of users. Not sure if they’ve changed anything since

    • hexbear because… Hexbear









  • Most cobol systems have more code that doesn’t do anything vs code that actually does something.

    What values do variables ROBERT1, ROBERT2 and ROBERT3 hold? Whatever ROBERT wanted.

    And when that system is storing high-risk and/or sensitive data, do you really want to be the person who deletes code that you think “actually does nothing”, only to find out it somehow stopped another portion of code from breaking?

    The reason why these things still exist is business laziness. They don’t know and don’t care what cobol is or isn’t doing.

    That’s the thing - tor a risk-averse industry (most companies running COBOL systems belong here), being the guy who architected the move away from COBOL is a high-risk, high-stress job with little immediate rewards. At best, the move goes seamlessly, and management knows you as “the guy who updated our OS or something and saved us some money but took a few years to do it, while Bob updated our HR system and saved a bunch of money in 1 year”. At worst, you accidentally break something, and now you have a fiasco on your hands.







  • It’s never been a technical reason, it’s the fact that most systems still running on COBOL are live, can’t be easily paused, and there’s an extremely high risk of enormous consequences for failure. Banks are a great example of this - hundreds of thousands of transactions per hour (or more), you can’t easily create a backup because even while you’re backing up more business logic and more records are being created, you can’t just tell people “hey we’re shutting off our system for 2 months, come back and get your money later”, and if you fuck up during the migration and rectify it within in hour, you would have caused hundreds/thousands of people to lose some money, and god forbid there was one unlucky SOB who tried to transfer their life savings during that one hour.

    And don’t forget the testing that needs to be done - you can’t even have an undeclared variable that somehow causes an overflow error when a user with a specific attribute deposits a specific amount of money in a specific branch code when Venus and Mars are aligned on a Tuesday.
