I get it, its just an expression we use in the industry. Its all good to hear it, but lets maybe stop using it.
Perhaps somebody doesn't like hcf opcodes because they remind them of when their house burned down. Is the concept of running into a blaze owned solely by firefighters? Do soldiers own the concept of battle?
That said, the grenade thing happened because, well, that's what some of us (internally) actually call that sort of outage situation sometimes -- you didn't make it happen, but you're there and are able to do something to fix it, so you do.
It doesn't work nearly as well on the outside, so I changed it and admitted my error. That's about the best you can do in a world where we're all speaking slightly different languages.
