            There's no need to do the approximation on the contours. For that specific image, you'll get one large contour, which you can simply get the bounding rectangle from, and crop the desired part. I optionally added setting the background transparent.

            Keydown event listener causes lagging, hanging, DOM thrashing in ReactJS
            Asked 2021-Feb-27 at 05:01

            I'm running a site locally and deployed with an 80 page modal in the React framework. I use state to move through the pages in the modal using the [currentStep, setCurrentStep] hooks. setCurrentStep can be invoked three ways- through back and next click button, through an input box by entering a page number and then hitting enter, and through the left and right keyboard keys. It's only the left and right keys that give me a problem. After several times clicking them (with pauses in between) the page becomes unresopnsive.

            I thought maybe it had something to do with listeners, blocking or too many unfinished calls, and I thought I could maybe find answers with features of dev tools like memory and event listener but these didn't help me. I noted that the input box option also used a similar event listener so I thought there could be an interaction somehow, so I changed it to a keyup listener and still go the same effects.

            Then I noticed as I clicked an arrow, the DOM started thrashing: mounting and unmounting a few sibling elements back and forth through two or three pages worth, which I can pick out despite the speed. Doing this in from the beginning I noticed the first time, it was normal. The second time it thrashed just a few times, and then it got higher and higher, almost like it was an n! function.

            What's interesting is that the other two methods (button and input) call the exact same setCurrentStep and nothing else. There must be some side effect happening or some difference somewhere, that makes think there needs to be a mount and unmount, despite them going through the same narrow pathways. I must be missing something. I am pretty sure it's not a data type issue. The next and back functions handle the incrementing and decrementing.

            You should add event listeners only once and remove listener after modals gone. For that, We can add listeners after React components mounted by using a useEffect hook. If you add listeners outside of useEffect hook, It will eventually add anonymous event listeners every render.

            Apart from trivial cases, it's often extremely hard to predict where the performance gains are. That's why you should benchmark your code before and after changes. Also profile your code to find where it spends most time.

            In other languages, this is where I break out a dictionary or hash set. Neither exist in C, so I have to weigh the complexity of adding something like that.

            TBH, it's not that complicated to implement. If you need the performance, it's a no brainer. But it's not guaranteed that it will be faster.

            I've considered sorting the list (i.e. first by X, then Y). But given the frequency of updates, I feel like I'll be thrashing the table far more than when iterating. But my knowledge of sorting algorithms is minimal.

            It's very likely that this is not optimal. But you can try it out. And you don't need to do a complete sort. Just do a binary search and move everything that comes after.

            Would a binary tree of some sort be any better here? Or would I again be spending all of my time re-balancing the tree?

            Only one way to find out. Try it and benchmark.

            Theoretically, given the (perceived) complexity of these algorithms, is there a threshold below which a linear search remains a viable option?

            I'm sure there are, but these always have to be balanced with reality. Like cache misses that can have a great impact on performance. One thing that might improve cache-friendlyness could be changing

            Hyper-Threading data cache context aliasing
            Asked 2020-Nov-05 at 19:06

            in intel's manual, the following section confuse me:

            11.5.6.2 Shared Mode In shared mode, the L1 data cache is competitively shared between logical processors. This is true even if the logical processors use identical CR3 registers and paging modes. In shared mode, linear addresses in the L1 data cache can be aliased, meaning that one linear address in the cache can point to different physical locations. The mechanism for resolving aliasing can lead to thrashing. For this reason, IA32_MISC_ENABLE[bit 24] = 0 is the preferred configuration for processors based on the Intel NetBurst microarchitecture that support Intel Hyper-Threading Technology.

            as intel use VIPT(equals to PIPT) to access cache.

            how cache aliasing would happened ?

            ...

            ANSWER

            Answered 2020-Nov-05 at 19:06

            Based on Intel® 64 and IA-32 Architectures Optimization Reference Manual, November 2009 (248966-020), Section 2.6.1.3:

            Most resources in a physical processor are fully shared to improve the dynamic utilization of the resource, including caches and all the execution units. Some shared resources which are linearly addressed, like the DTLB, include a logical processor ID bit to distinguish whether the entry belongs to one logical processor or the other.

            The first level cache can operate in two modes depending on a context-ID bit:

            • Shared mode: The L1 data cache is fully shared by two logical processors.
            • Adaptive mode: In adaptive mode, memory accesses using the page directory is mapped identically across logical processors sharing the L1 data cache.

            Aliasing is possible because the processor ID/context-ID bit (which is just a bit indicating which virtual processor the memory access came from) would be different for different threads and shared mode uses that bit. Adaptive mode simply addresses the cache as one would normally expect, only using the memory address.

            Specifically how the processor ID is used when indexing the cache in shared mode appears not to be documented. (XORing with several address bits would provide dispersal of indexes such that adjacent indexes for one hardware thread would map to more separated indexes for the other thread. Selecting a different bit order for different threads is less likely since such would tend to increase delay. Dispersal reduces conflict frequency given spatial locality above cache line granularity but less than way-size granularity.)

            For instance, general_log_file="A.log"

            could be general_log_file=./general.log

            to be descriptive of the log filename in Windows in your current datadir

I would also like to make the outside border of the table 3px and maybe the horizontal borders that run the full width of the table.
