So I'm struggling with this task for a while and I really can not know what to do. The problem is when i try to fetch the data from "/menu/items" and then pass it as prop to Card.js I get the information that "Cannot read properties of undefined (reading 'name')" in Card.js.
So I have to Components:
Menu.js
...ANSWER
Answered 2022-Jan-30 at 17:04First you need to do is export the json and import it on parent and pass the json as props in card.
After that you can map the props json and distribute it on what ever you want.
Using fetch you need to use UseEffect after fetching it store it in useState and pass it on Card component.
QUESTION
I have problems with memory consumption at my software using golangs lib encoding/base64
My software is splitting a videofile to separate images, (gocv mat) converting them to base64 string and saving it to file in json format.
During testing I found that the memory usage is piling up until the oom-reaper is killing the process.
Investigation with pprof showed that the encoding/base64 memory seems to pile up.
I did pprof snapshots after each image frame, and allocated mem of encoding/base64 is raising from 976.89kB(flat) to 4633.54kB(flat) shortly before oom-reaper was killing the process.
...ANSWER
Answered 2022-Jan-26 at 13:47To answer your questions:
How can I release the memory of "encodedString" in this case that it does not pile up?
You cannot and you need not. Unused memory is "freed".
Or is it maybe not my wrong coding, and the mem-leak is at the lib base64 ?
No, package encoding/base64 has no memory leak. (Chances are 0 that you detect a memory leak in a trivial function in the standard library of a garbage collected language.)
To guide you towards a solution:
Your application uses absurd amount of memory but that's because a) processing video and images is memory hungry and b) you seem to do nothing to keep memory low: E.g. you encode the whole image into a bytes.Buffer, then encode the whole bytes.Buffer to a string then work on that string and so on. You probably should encode the image into a stream, encode this stream to base64 and stream this output further to where it deposited. This is totally painless in Go as all these encoders work on io.Writers which can be chained very easily.

QUESTION
Inside a more complex script in LUA, I created the following function, that is supposed to retrieve the list of all audio files located into a directory, which is specified when the function is called (first parameter).
The function returns a formatted HTML line or a CSV one, based on the value of the 2nd parameter.
If 1, it returns HTML If 2, it returns CSV
This function works fine unless path and/or file names don't have accented letters or umlauts. Then fails.
here an exaggerated example, with which I've made tests:

QUESTION
I made a hangman program using C programming language. It compiles(gcc) without an error, but it when I try to execute the program(./a.out), it gives me segmentation fault. I believe that it is due to the use of file pointer, because before adding the file pointer, it worked perfectly fine. After adding a file pointer to keep track of the score, it kept giving me segmentation fault. It compiles(gcc) without an error, but it when I try to execute the program(./a.out), it gives me segmentation fault. I need to know what exactly is causing the segmentation fault.
Here is the file pointer section of my code
