QUESTION
I am working on a project in which I need to post a new Course to my API. I tested this with POSTMAN and API works just fine, however when I try to post data using react fetch data is corrupted. While sending single strings like dishName: "pizza" works just fine and is shown in database I cannot manage to send an array of objects. I tried to do it in many ways like:
...ANSWER
Answered 2021-May-27 at 21:44You are setting the ingredients
state as a string, so you are basically 'stringify' a string which will result in JSON SyntaxError
. If you want to send an array that way you must specify the array bracket [
and ]
in order to make it a valid array.
To solve it just change:

This is my flow: Content script -> Fetch data using background.js -> Return data and inject the new HTML into the webpage.
Now I have to show a tooltip using Popper.js but I get the error "document" is undefined. It's strange because I am in content-scripts.js. How can I get the newly updated dom after my injection?

QUESTION
To start off, regex is probably the least talented aspect within my programming belt, this is what I have so far:
\D{1,5}(PR)\D+$
\D{1,5}
because common stock symbols are always a maximum of 5 letters
(PR)
because that is part of the pattern that needs to be searched (more below in the background info)
\D+$
because I'm trying to match any single letter at the end of the string
A small tidbit of background
Preferred stock symbols are not standardized and so every platform, exchange, etc has their own way to display them. Having said that, most display a special character in their name, which makes those guys easy to detect. The characters are
[] {'.', '/', '-', ' ', '+'};
The trickier ones all have a similar pattern:
{symbol}PR{0}
{symbol}p{0}
{symbol}P{0}
Where 0
is just any single letter A-Z
Here is a sample data set for the trickier ones:

QUESTION
I am trying to write a buffer for an audio system with Oboe, the do and don'ts are
Callback do's and don'ts You should never perform an operation which could block inside
onAudioReady
. Examples of blocking operations include:allocate memory using, for example,
malloc()
or new;file operations such as opening, closing, reading or writing;
network operations such as streaming;
use mutexes or other synchronization primitives sleep
stop or close the stream
Call
read()
orwrite()
on the stream which invoked it
Audio thread reads from my buffer and decoder thread writes to it and as you can imagine its all good until threading issues kicks in. My main problem is I can just use a mutex to overcome this issue but if i do so I will be blocking one of the threads and if audio thread is blocked then the sound basically not played resulting in "popcorn" sound. (A Sound that is so disturbing to listen to)
I play the sound through a callback where I feed the data to it.
...ANSWER
Answered 2020-Nov-23 at 13:43You can use a thread-safe lock-free queue for reading/writing data. This will avoid the need for mutexes, will be much faster and should fix your "popcorn" issues.
An example implementation can be found here: https://github.com/google/oboe/blob/master/samples/RhythmGame/src/main/cpp/utils/LockFreeQueue.h
