Of course the shouting episodes all happened during the era I was doing WordPress dev.

So we were a team of consultants working on this elephant-traffic website. There were a couple of systems for managing content on a more modular level, the "best" being one dubbed MF, a spaghettified monstrosity that the 2 people who joined before me had developed.

We were about to launch that shit into production, so I was watching their AWS account, being the only dev who had operational experience (and not afraid to wipe out that macos piece of shit and dev on a real os).

Anyhow, we enable the thing, and the average number of queries per page load instantly jumps from ~30 (even vanilla WP is horrible) to 1000+. Instances are overloaded and the ASG group goes up from 4 to 22. That just moves the problem elsewhere as now the database server is overwhelmed.

Me: we have to enable database caching for this thing *NOW*

Shitty authors of the monstrosity (SAM): no, our code cannot be responsible for that, it's the platform that can't handle the transition.

Me: we literally flipped a single switch here and look at the jump in all these graphs.

SAM: nono, it's fine, just add more instances

Me: ARE YOU FUCKIN SERIOUS?
Me: - goes and enables database caching without any approvals to do so, explaining to mgmt. that failure to do so would impair business revenue due to huge loading times, so they have to live with some data staleness -

SAM: Noooo, we'll show you it's not our code.
SAM: - pushes a new release of the monstrosity that makes DB queries go above 2k / page load -

...

Tho on the bright side, from that point on I focused exclusively on performance, was building a nice fragment caching framework which made the site fly regardless of what shitty code was powering it, tuned the stack to no end and learned a ton of stuff in the process which allowed me to graduate from the tar pit of WP development.

Learning New Design Patterns...

When all you've got is a hammer, everything looks like a nail. Arg.

Recently, my code in almost any controller is like so:

return (new MyFancyClass($param))->methodThatHandlesIt();

that can't be the solution to everything.... although it kind of is
how can I beef up on patterns and avoid crushing a screw into the wall without realizing it's not a nail
