Ah, yeah I see it now. That one in the upper right could possibly be a dragon tongue, but the green beans in the foreground 100% are not.
Immature pods on dt are skinnier, the purple is at its darkest, and they have a green tint. As they mature they lose the green and get more yellow between the purple, and when they're fully mature the purple fades and they become almost completely yellow/white. I thought you might have grown a different bean because you described them as stringy and said they weren't tender anymore by the time they developed their splotches, but my experience is that their splotches are darkest when they're immature, and they stay tender without any stringiness until the seeds inside are developed enough for the pods to bulge. Could just be a difference in climate for all I know (I'm in the high desert).
Attached picture is a pile of dt bean pods I harvested in various stages of ripeness.
I think you may have grown a different bean. I grow Dragon Tongue beans every year as garden snacks and they look pretty different than the OP picture.
Huh. I expected to wander in here and see people confused about why this is on unpopularopinion. I'm apparently a repulsive philistine. A meteorite-forged knife sharpened on daylight is a joy to use, but you can also just buy cheap stamped knives, do basic maintenance, and spend your mental capital elsewhere if you want.
Maybe "credentialed" wasn't the right word. I was thinking of software licenses and access to third party tools and systems. Probably not as big a mess in game dev as it is in government.
It's called Brook's Law. It takes a lot of time and effort getting people up to speed, and that takes experienced devs away from coding. You also have to get them credentialed, teach them the tools, need extra code reviews/testing/bugfixes while they learn the quirks and pitfalls of the code base, etc. In the long term you'll be able to get more done, but it comes at the cost of short term agility.
