I apologize if this comes out as negative, but it truly is an honest question.

They are a tens-of-billions company. Why is this news? Shouldn't this be just part of doing business?

View on HN

Because it's a helpful contribution to the the engineering community?

Helpful how? They used a third party library and they didn’t even mentioned it.

Their goal wasn't to shame the library, but to indicate how one might do the same in their app. (And show that they have good engineers :P)

Doordash is a zombie company propped up by VCs, their tech is trash. I remember reading their "ML Engineering blog" and it was the most elementary crap every, they just used google maps apis for delivery and we're trying to do point in polygon calculations. The fact they herald things that are kind of simple and obvious to speaks volumes.

It's their engineering blog... This is what engineering blogs talk about and you are on hacker news where things like this are of interest.

Many people here are iOS developers who would like to see how to improve launch times in their own app.

Recruiting

That’s quite nihilistic.

Why are any of the other posts on HackerNews here? Many are less technical or less interesting, depending where your interests are.

This post at least shows how certain things might be debugged and some performance tweaks that people might forget to make.

The bar for interest is arbitrary. One can choose to not engage and move on if they don’t think it’s interesting.

It's an engineering blog targeting other engineers. Some engineers discovered something that had a significant impact so they are communicating it to more engineers.

It's just PR, and/or some internal stunt by the eng team for better performance reviews. Both of which are fine, if the article itself is actually useful. In this case, I feel like the only thing that could have been interesting is the dyld workaround, but they don't go into depth with that at all. The first two "solutions" feel like they were just doing it inefficiently in the first place, rather than some novel technique worth sharing

Most performance wins are someone doing something inefficiently in the first place. Shocker!
