CS 484 Fall 23: blind coding of HW2 (React)
This is me doing the React homework assignment and talking through my thought process. It should be helpful for people to understand how to both work through a React project as well as understand the problem solving strategies one might use during a programming assignment.

    Hey, you posted this video twice ("The magic of page miss" is the same video as "The magic of page fault". Excellent content by the way, I am following all your courses as an open source coder eager to learn more and build his own software :D Your explanations are the best I could find on the internet so far. What a precious resource !

    crazy I'm doing this because my uni just brought in a new teacher for systems prog and he just does what everrrrr and wings everything and has zero clue what anything is or even test if the random stuff he gets on google actually works before assigning it lol. we have not been shown a SINGLE line of code in class. but we have coding assignments. he has not shown anything, at all. I have no idea what systems programming is even supposed to be about.

    we should not need separate not_full and not-empty conditional variables. Also probably should avoid signaling if queue size wasn't empty or full before out change.

    using pthread_mutex in place of a Posix semaphore though, we have one process (first reader) locking a mutex and a different process (last leaving reader) unlocking it. This is not allowed with mutexes. Which is why we would usually use semaphore(1) instead

    5:48 'As application developers we don't need to know how it works, just that it does', lol what? Who knows how it works then if not application developers? This is probably why so many aiming for entry level position have trouble landing work... "Uhm sorry sir I don't know how it works just that it does - that'll be $75/hour please" - If i google how to install a door I generally am expecting the tutor to know how to install a door. Is there an analogy for the difference in unix and af_inet sockets? At my next programmer interview I just answer each problem with 'click download', cheers!

    Gemini 1.5 Pro: This lecture is about memory mapping (mmap) and its role in virtual memory. The speaker, Chris Kanich, explains that memory mapping is a technique that allows a process to access a file as if it were directly mapped into its memory address space. This means that the process can read and write to the file using normal memory access instructions, without having to explicitly call read or write system calls. [1,2] One of the benefits of memory mapping is that it can improve the efficiency of memory access. When a process reads from a file using traditional read system calls, the data must be copied from the kernel address space to the user address space. This copying can be time-consuming. With memory mapping, the data is already in the process's address space, so there is no need to copy it. [1,2] Another benefit of memory mapping is that it can simplify the process of sharing memory between processes. Two processes can map the same file into their respective address spaces, and any changes made by one process will be immediately visible to the other. This can be useful for things like shared libraries, which can be mapped into the address space of multiple processes at the same time. [2] The lecture also discusses the concept of copy-on-write (COW). COW is a technique that allows multiple processes to share a read-only page of memory. The first process to write to the page will cause a page fault, and the kernel will create a private copy of the page for the writing process. This means that the original page can still be shared by other processes, and the writing process will not affect them. [2] Overall, memory mapping is a powerful technique that can improve the efficiency of memory access and simplify the process of sharing memory between processes.

    It is also worthwhile to test that the system does what the documentation seems to imply it should do. Try mmap on a large file using different flags, see what happens when the file is cashed in main memory.
