rtc | Real-Time Communication Infracture | Socket library

I'm trying to put text into a RichTextCtrl and then, after the user has made edits, I want to get the edited text back out along with the styles. Its the second part I'm having trouble with. Out of all the methods to get styles out of the buffer, none of them are really user-friendly.

The best I've come up with is to walk through the text a character at a time with GetStyleForRange(range, style). There has got to be a better way to do this! Here's my code now, which walks through gathering a list of text segments and styles.

Please give me a better way to do this. I have to be missing something.

I'm having problems with the logic to build behind the webRTC multi peer connections handling. Basically I'm trying to make a Room full of people in a videoconference call. I'm using the basic WebSocket library provided by js, and React for the frontend and Java (spring boot) for the backend.

As of my understanding right now this is what I managed to write down (filtered based on what I "think" is relevant)

This is my web socket init method (adding listeners)

In my application I have a field called created_at predefined as CURRENT_TIMESTAMP. My all application (PHP) is configured to timezone America/Recife -03, but when I insert a data it's saved to another timezone, e.g current time is 20:34 and it's saved as 11:34.

• OS: [Debian 9 Strech]
• Database: [10.1.48-MariaDB]

I've modified local time to date I need and RTC as well.

• date output: Sat May 1 20:42:05 -03 2021
• timedatectl output: Local time: Sat 2021-05-01 20:42:16 -03, Universal time: Sat 2021-05-01 23:42:16 UTC, RTC time: Sat 2021-05-01 20:42:16, Time zone: America/Recife (-03, -0300)

I have this line of C code from a real time clock (RTC) driver for a SoC chip from Nordic. I tried to look for what it does but it's a bit difficult to search. Can anyone please let me know what does it do? Especially the parentheses and asterisk.

I am trying to connect my javascript app AWS WebRTC with a Cognito user to get its credentials dynamically but faced the following error code:

json.js:52 Uncaught (in promise) CredentialsError: Missing credentials in config, if using AWS_CONFIG_FILE, set AWS_SDK_LOAD_CONFIG=1

I have done hard coding my credentials into the configuration and it has work successfully, however that's a bad practice hence I am trying to get AWS Web RTC credentials via my Cognito user. I have setup user pool and link in to my federal identities already. The credentials are now managed by AWS Amplify which loads AWS user profile from config file (./aws/credentials).

Following this two guides:

1. https://docs.aws.amazon.com/cognito/latest/developerguide/amazon-cognito-integrating-user-pools-with-identity-pools.html
2. https://docs.aws.amazon.com/cognito/latest/developerguide/getting-credentials.html

I've written the following snippet to get my credentials but now faced the error.

I'm trying use Agora Rtc WEB api for voice/video chat.

It will be just 1:1 call, and I want that one side can invoke notification/send message to other side (e.g. something like send emoji "call reactions" in Skype).

In reality it will not be invoked just by user, but I want some side channel to transfer some data during call, it will be only few bytes, but I need it in-sync with video/audio.

I'm looking for sendMetadata(), but it is not supported on WEB platform?

Is possible to have custom track? So I can do "client.publish(sideChannelDataTrack);" ?

Or the only way is to use both RTC and RTM together, even for 1:1 call?

Thanks for reactions.

Background:

I have an old Seagate BlackArmor NAS 110 that I'm trying to install Debian on by following the instructions here: https://github.com/hn/seagate-blackarmor-nas.

I have a couple of USB to TTL serial adapters (one FTDI chipset and the other Prolific) that I've tried and have run into the same issue with both. I have made the connection to the serial port on the board of the NAS using a multimeter to make sure I've gotten the pinout correct.

Problem:

I'm not able to stop the autoboot process by pressing keys and any point during the boot process. The device also does not seem to respond to any keystrokes although they are echoed back.

What I've Tried So Far:

• Using USB to TTL serial adapters with two different chipsets
• Using the adapters on two different computers (MacBook Pro and a ThinkPad)
• Using different operating systems (MacOS, Windows 10, Ubuntu 20.04)
• Using different terminal programs (Screen, Minicom, Putty)
• Turned off hardware and software flow control
• Tested output of adapters by shorting RX and TX pins and seeing keystrokes echoed back
• Commands seem to be sent to device as when I type I see my commands echoed back (not sure if this is supposed to happen)

I've been at this for a few days and can't figure it out. I've also recorded my screen while experiencing the issue: https://streamable.com/xl43br. Can anyone see where I'm going wrong?

Terminal output while experiencing the problem:

As mentioned in image my app is violating there policy but i've another app for the same which is for doctor's and that app is using the same libraries and almost everything similar to this app but still my doctor app is accepted without any violation

androidx.fragment.app.FragmentActivity.startActivityForResult and they are saying your startActivityForResult is responsible for this but i'm only calling this line for opening camera and gallery.

i've tried uploading my app multiple time's with upgraded gradle and there remediations available here https://support.google.com/faqs/answer/9267555 but still no success.

I have a SpringBoot Kafka streams maven app. I use a spring-boot-starter-parent 2.4.4 for my springboot dependencies and kafka-streams 2.7.0.

I am stuck at running tests with

java.lang.NullPointerException when trying to load my application configuration from either resources/application.yml or test/resources/application-test.resources or test/resources/application.yml

I have a Config class with this annotations and getters and setters for fields, which are defined with same name as in the application.yml
