Python is (in)famous for its "batteries included" approach to a standard library, but it's not that notable that it has plenty of standard data structures, like dicts. Nor is in surprising that dicts have all sorts of useful methods, like pop, which removes a key from the dict and returns its value.

Because you're here, reading this site, you'll also be unsurprised that this doesn't stop developers from re-implementing that built-in function, badly. Karen sends us this:

Industrial machines are generally accompanied by "Human Machine Interfaces", HMIs. This is industrial slang for a little computerized box you use to control the industrial machine. All the key logic and core functionality and especially the safety functionality is handled at a deeper computer layer in the system. The HMI is just buttons users can push to interact with the machine.

Purchasers of those pieces of industrial equipment often want to customize that user interface. They want to guide users away from functions they don't need, or make their specific workflow clear, or even just brand the UI. This means that the vendor needs to publish an API for their HMI.

I've had the misfortune of working in places which did source-control via comments. Like one place which required that, with each section of code changed, you needed to add a comment with your name, the ticket number, and the reason the change was made. You know, the kind of thing you can just get from your source control service.

In their defense, that policy was invented for mainframe developers and then extended to everyone else, and their source control system was in Visual Source Safe. VSS was a) terrible, and b) a perennial destroyer of history, so maybe they weren't entirely wrong and VSS was the real WTF. I still hated it.

Antonio has an acquaintance has been seeking career advancement by proactively hunting down and fixing bugs. For example, in one project they were working on, there was a bug where it would incorrectly use MiB for storage sizes instead of MB, and vice-versa.

We can set aside conspiracy theories about HDD and RAM manufacturers lying to us about sizes by using MiB in marketing. It isn't relevant, and besides, its not like anyone can afford RAM anymore, with crazy datacenter buildouts. Regardless, which size to use, the base 1024 or base 1000, was configurable by the user, so obviously there was a bug handling that flag. Said acquaintance dug through, and found this:
