Even factorio started out on tried-and-tested libraries before moving away from them primarily because of optimization concerns (right?)
Keep it super simple. Or that game will never come out.
> Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%.
Sometimes the best way to tackle that 3% is upfront when you're deciding on your system architecture.
So a day on their game wasted over efficiently removing an item from an array of 20 items every 5-10 minutes.
> If I optimize this, how much time is it going to save the whole world? What will be the sum of time saved by everyone who will ever run this code? Is that less than the time required of me to do the optimization? Then, don’t do it!
That question was relevant quite often.
The big optimizations though really mattered. And, required planning before initial implementation to set the system up to be optimizable.
Reminds me of when another subreddit was mocking some legacy code (I think Motorola? Some mobile device stuff) for using bubble sort. Meanwhile, the sort probably wasnt on more than a fee hundred items and the mobile embedded is constrained for space. Bubble sort is easy to read, write and has O(1) space. Performance isn't a concern at the scale being worked at. We're talking maybe microseconds of difference.
It's not necessarily a bad thing that acedemia focuses on theory. But we keep using school to put a square peg into a round hole and wonder why students are so unprepared for actual production.
It's ultimately the company's fault. If you want certain skills, you need to train for it. Your processes aren't public, so you can't just expect candidates to magically know what matters to their role.

now acedemically: the answer is to swap an item to the end and reduce the buffer size. I don't think that's taught in acedemia either, but that's a trick you learn on the job. When and if you do need it.
