            If you want to use sort or sorted you have to define a key function for the comparison. This key function has to give back a tuple of the number of vocals and the position of the first vocal.

            One problem is: you only increment the iterator if the name matches. If the name does not match, the iterator stays the same, and it gets into an infinite loop.

            Try moving the iterator outside the if statement:

            TTN decoder - Node-red
            Asked 2021-Jun-08 at 05:25

            In TTN they are no longer supporting large decoders.

            I know what the decoder needs to be in TTN, it is in my DECODER function, but dont know how to execute it in the function node.

            If you use inject Payload [1,2,3] RAW, it injects the raw payload that is msg.payload.payload.uplink_message.frm_payload into the decoder.

            The DECODER needs to decode the raw payload and output it in msg.payload.uplink_message.decoded_payload

            If you use inject Payload [1,2,3] Decoded in the flow you see how the end result needs to look like and the decoded msg.payload.uplink_message.decoded_payload

            WAVE file unexpected behaviour
            Asked 2021-Jun-04 at 09:08

            I am currently trying to make a .wav file that will play sos in morse.

            The way I went about this is: I have a byte array that contains one wave of a beep. I then repeated that until I had the desired length. After that I inserted those bytes into a new array and put bytes containing 00 (in hexadecimal) to separate the beeps.

            If I add 1 beep to a WAVE file, it creates the file correctly (i.e. I get a beep of the desired length). Here is a picture of the waves zoomed in (I opened the file in Audacity): And here is a picture of the entire wave part:

            The problem now is that when I add a second beep, the second one becomes completely distorted: So this is what the entire file looks like now:

            If I add another beep, it will be the correct beep again, If I add yet another beep it's going to be distorted again, etc. So basically, every other wave is distorted.

            Does anyone know why this happens?

            Here is a link to a .txt file I generated containing the the audio data of the wave file I created: byteTest19.txt

            And here is a lint to a .txt file that I generated using file format.info that is a hexadecimal representation of the bytes in the .wav file I generated containing 5 beeps (with two of them, the even beeps being distorted): test3.txt

            You can tell when a new beep starts because it is preceded by a lot of 00's.

            As far as I can see, the bytes of the second beep does not differ from the first one, which is why I am asking this question.

            If anyone knows why this happens, please help me. If you need more information, don't hesitate to ask. I hope I explained well what I'm doing, if not, that's my bad.

            The problem

            Your .wav file is Signed 16 bit Little Endian, Rate 44100 Hz, Mono - which means that each sample in the file is 2 bytes long, and describes a signed amplitude. So you can copy-and-paste chunks of samples without any problems, as long as their lengths are divisible by 2 (your block size). Your silences are likely of odd length, so that the 1st sample after a silence is interpreted as

            = is used for assignment but not for comparison.

            == or === for comparison.

            Since for loop starts perfectly but when it goes to if condition, first of all you're not checking for equality instead you are assigining to json[i].name which is the first element/object of json arrray to whatever ~"{HOST.NAME}" returns which would be -1(see the below snippet).

            Then you console.log that object i.e json[0] and you're assigning the result of JSON.stringify(json[i]) to res and return the result.

            The thing is that when you open MainActiity that time onMapReady() called first automatically before LocationCallback. Eventually, it will return null latitude and Longitude.

            However, your problem is that you haven't assigned your map fragment.

            first of all, you need to assign in onLocationResult() below the for loop.
