Outlook at that issue even in their old C++ (I think) version.

You're in London, you save your friend's birthday as March 11th.

You're now in SF. When is your friend's birthday? It's still all-day March 11th, not March 10th, starting at 5PM, and ending March 11th at 5PM.

Couple of things to add:

McKinsey has a weird structure where there are too many cooks in the kitchen.

Everybody there is reviewed on client impact, meaning it ends up being an everybody-for-themselves situation.

So as a developer you have little guidance (in fact, you're still being reviewed on client impact, even if you have 0 client exposure).

Then a (Senior) Partner comes in with this idea (that will get them a good review), and you jump on that. After all, it's all you can do to get a good review.

You work on it, and then the (Senior) Partner moves on. But it's not done. It's enough for the review, but continuing to work on it doesn't bring you anything, in fact, it will actually pull you down, as finishing the project doesn't give immediate client results.

So what does this mean? Most products of McKinsey are a grab-bag of raw ideas of leadership, implemented as a one-off, without a cohesive vision or even a long-term vision at all. It's all about the review cycle.

McKinsey is trying to do software like they do their other engagements. It doesn't work. You can't just do something for 6 months and then let it go. Software rots.

The fact that they laid off a good amount of (very good) software engineers in 2024 is a reflection on how they see software development.

And McKinsey's people, who go to other companies, take those ideas with them. Result: The UI of your project changes all the time, because everybody is looking at the short-term impact they have that gets them a good review, not what is best for the project in the long term.

Caching headers?

(Which, on Akamai, are by default ignored!)

I did not enable this and yet I got the panel in the UI.

I refuse to eat Srirarcha due to its use of Xantan gum.

Using Xantan gum is a sign of ultra processing. It's used to change mouth-feel, which is basically lying to the body.

I always recommend people to read / listen to https://www.amazon.com/Ultra-Processed-People-Science-Behind... to understand these ingredients and what they do to our bodies.
