| 2024-12-22 06:13:46 +0100 | <monochrom> | So even the "eager : lazy :: strict : non-strict" "correspondence" is easily broken. |
| 2024-12-22 06:13:16 +0100 | <monochrom> | there is also speculative evaluation, it can result in non-strict while being even more eager than eager. |

| 2024-12-22 06:12:09 +0100 | <monochrom> | eager and lazy |
| 2024-12-22 06:12:02 +0100 | <monochrom> | denotational means you only talk about whether you get an answer and what answer if yes, it deliberately avoids how the computer manages to do it. |
| 2024-12-22 06:11:46 +0100 | <haskellbridge> | <Bowuigi> So what do you call the operational notion? |
| 2024-12-22 06:10:45 +0100 | <monochrom> | Ugh no, strictness is a denotational notion, not an operational (evaluation) notion. A strict function means f bottom = bottom. |

| 2024-12-22 06:09:37 +0100 | <haskellbridge> | <Bowuigi> Strict evaluation would evaluate the value once and possibly duplicate other computations inside that value |
| 2024-12-22 06:08:37 +0100 | <haskellbridge> | <Bowuigi> Space leaks are caused by duplication of code, code is duplicated wherever variables are duplicated in lazy evaluation |

| 2024-12-22 06:07:30 +0100 | <orangeflu> | and why is the laziness causing me space leaks while strictness wouldn't? |
| 2024-12-22 06:06:35 +0100 | <haskellbridge> | <Bowuigi> "Eager" is "fully evaluate", "Strict" is "evaluate only what I'm directly responsible for" and "Lazy" is "evaluate only what I will pattern match on, as I pattern match on it". Or at least that seems to be the general consensus |

| 2024-12-22 06:04:16 +0100 | <haskellbridge> | <Bowuigi> Yes, but not eagerly either |
| 2024-12-22 06:03:41 +0100 | <orangeflu> | when you say 'strict', do you mean not lazily? |

| 2024-12-22 06:02:43 +0100 | <haskellbridge> | <Bowuigi> Passing state around in a strict way, along with nice syntax sugar is what this is supposed to do |
| 2024-12-22 06:01:02 +0100 | <orangeflu> | anyway) |
| 2024-12-22 06:00:55 +0100 | <orangeflu> | i know what a state monad is, i think. like, if i have a function, that takes a container and returns a modified container and a result, i can chain them together with do notation. that's what i understand anyway. But how is that different from what i'm doing now? except for the fact that i don't chain them in a do block (which wouldn't be useful anyway, cause i don't execute instructions that way |

| 2024-12-22 05:58:10 +0100 | <haskellbridge> | <Bowuigi> Hmmm moving to a strict state monad to handle your emulator state could also help. It attacks space leaks more directly and is a smaller change |

| 2024-12-22 05:56:06 +0100 | <haskellbridge> | <Bowuigi> MVector is a somewhat extreme solution, mutable stuff is fairly common in heavily optimized programs/libraries like smalltt or flatparse (there are a lot more examples but I know those two more in depth than anything else) |

| 2024-12-22 05:55:02 +0100 | <orangeflu> | thing is, this is both a learning project and something that i want to be useful |
| 2024-12-22 05:54:35 +0100 | <orangeflu> | i'm sure i did a horrible job of writing this and there are a bunch of stuff that make no sense or could be optimized heavily |
| 2024-12-22 05:53:42 +0100 | <haskellbridge> | <Bowuigi> There might be a more obvious refactor that we missed tho |
| 2024-12-22 05:52:47 +0100 | <haskellbridge> | <Bowuigi> Just like optimization in other languages ofc |

| 2024-12-22 05:52:25 +0100 | <haskellbridge> | <Bowuigi> With MVector you need something like IO everywhere yes. Haskell optimization is not for begginners |
| 2024-12-22 05:51:38 +0100 | <orangeflu> | This seems more trouble than its worth considering I don't even understand how to use, let alone modify all my pure functions into using it atop of my InputT IO stuff |
| 2024-12-22 05:51:38 +0100 | <haskellbridge> | <Bowuigi> c_wraith you might be able to help more with this, the codebase is in https://github.com/Flu/avr-emulator and the profiling results are in https://paste.tomsmeding.com/b9owLIrr |

| 2024-12-22 05:50:50 +0100 | <orangeflu> | Does that mean now I will need to have IO everywhere? |
| 2024-12-22 05:50:33 +0100 | <orangeflu> | well, the idea is to transition to mvectors, but i thought it would be easier. I am also using InputT IO (EmulatorState) in my REPL because i am using haskeline, so not sure how that is going to affect things with mvector. Also, there is also the functionality for reading a file and then ditching the IO after that, before executing |

| 2024-12-22 05:43:35 +0100 | <haskellbridge> | <Bowuigi> The Array here was used as if it was a mutable one (it was the original idea, but the name Array was somewhat misleading since it isn't a C array) |
