Try replacing getchar() with getwchar(); I think you're right that its a Windows-only problem.

I think the problem is that getchar(); is expecting input as a char type, which is 8 bits and only supports ASCII. getwchar(); supports the wchar_t type which allows for other text encodings. "😁" isn't ASCII, and from this page: https://docs.microsoft.com/en-us/windows/win32/learnwin32/working-with-strings , it seems like Windows encodes extended characters like this in UTF-16. I was having trouble finding a lookup table for utf-16 emoji, but I'm guessing that one of the bytes in the utf-16 "😁" is 0x39 which is why you're seeing that printed out.

You're asking for all the symbols (exchangeInfo) and then getting the candle info (klines) for each symbol (= currency pair).

You can do so just for the GBP pairs by looking for GBP in the two currencies you're currently iterating on, by adding this to your foreach:

Videos are playing too fast using OpenCV and PyQT5

Asked 2021-Jun-14 at 10:44

My GUI is able to play videos automatically when selected in the QListWidget. However, instead of normal speed, the videos play very fast. I use 720p Mp4 videos as examples and are placed in a certain folder. I tried using cv2.CAP_PROP_FPS and cv2.CAP_PROP_BUFFERSIZE, but they are both not working. I am using pyqtSignal in the QThread and the convert_cv_qt function which I saw in other guides. How do I play the videos in normal speed / frame rate?

Answered 2021-Jun-14 at 10:44

When you use VideoCapture with a file if you call "cap.read()" you will obtain the next frame on the video, regardless of its actual framerate. Hence, you should use a "msleep" every time you capture a frame:

In general, when using gcc inline asm on x86, you NEVER want to include mov instructions, or explicit registers in the asm code. Instead, you want to use the constraints to force inputs and output into specific registers. The constraints available are:

EMBEDDED C - Volatile qualifier does not matter in my interrupt routine

Asked 2021-Jun-13 at 19:31

I am new to embedded C, and I recently watched some videos about volatile qualifier. They all mention about the same things. The scenarios for the use of a volatile qualifier :

when reading or writing a variable in ISR (interrupt service routine)
RTOS application or multi thread (which is not my case)
memory mapped IO (which is also not my case)

My question is that my code does not stuck in the whiletest();function below when my UART receives data and then triggers the void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) interrupt function

...

ANSWER

Answered 2021-Jun-13 at 16:12

volatile informs the compiler that object is side effects prone. It means that it can be changed by something which is not in the program execution path.

As you never call the interrupt routine directly compiler assumes that the test variable will never be 1. You need to tell him (volatile does it) that it may change anyway.

Java Special Symbol Serialization

Asked 2021-Jun-13 at 15:30

I wanted to know how does a primitive character is serialized in java. I serialized a class to understand how byte information is stored in java. Following is the class which I serialised.

...

ANSWER

Answered 2021-Jun-13 at 15:30

Java strings are UTF-8 encoded in the default serialization.

You can see the full specification of UTF-8 summarized on the Wikipedia page.

Notice that characters between 0x00 and 0x7F are stored as-is, as one byte, but characters 0x80 through 0x07FF are stored as a two-byte sequence, 110xxxxx 10xxxxxx, where the 'x' represent the sequential eleven bits used for values in that range.

Your char 128 is in that range, with bit sequence 00010000000. So the corresponding two-byte UTF-8 sequence is 11000010 10000000, or -62, -128 if you interpret those as signed 8-bit characters.

(The Java version of UTF-8 is actually slightly different than what's on the Wiki for some special characters, but it doesn't affect this string!)

The log shows that the ResourcesPlugin is being found but its plug-in activator is getting a null pointer exception when it tries to get the IContentTypeManager.

The content type manager is provided using OSGi declarative services but you have not included org.apache.felix.scr which deals with this.

So at a minimum you need to include org.apache.felix.scr and start it in the section:
