make-ca | PKI setup script for LFS | TLS library

I have an API that opens a pdf file in a browser, I want to call that programmatically from another WinForms project(Both in the same solution).

Here is the Controller and setups:

app.UseCors();

I want to create a new outbound call to a phone number via the API that should be handled by a TwiML App.

To do this, I provide the ApplicationSid parameter instead of the Url parameter as documented here

But I cannot find a way to pass any custom parameters as the only way to add custom parameters when creating a call to a phone number is to add them as query parameters to the URL as described here.

I could query the TwiML App from the API, read the configured Webhook URLs, add my custom Parameters as Query and pass them to Url, StatusCallback and FallbackUrl when creating the Call but that seems redundant and overcomplicated.

Another solution would be to store the custom parameters in a local database with the CallSid as key, but I would like to avoid having local state.

Is there no way to simply tell the API to add some parameters to the Url when calling the webhooks of the TwiML App (as mentioned here)?

Wondering if there's a "proper" way of converting an Enum to a &str and back.

The problem I'm trying to solve:

In the clap crate, args/subcommands are defined and identified by &strs. (Which I'm assuming don't fully take advantage of the type checker.) I'd like to pass a Command Enum to my application instead of a &str which would be verified by the type-checker and also save me from typing (typo-ing?) strings all over the place.

This is what I came up with from searching StackOverflow and std:

I need to create an app for iOS that lets the user to call any number via VoIP. I'm trying to implement the quickstart guide for twilio that I found here: https://www.twilio.com/docs/voice/voip-sdk/ios/get-started#bullet9

The app starts well but when I insert a number and press on "Call", a voice says me that an error occurred. In the twilio console I found this error:

An attempt to retrieve content from https://my-quickstart-dev.twil.io/make-call returned the HTTP status code 404

But I cannot understand what it means... that URL is from the tutorial... with which URL I should substitute it? In addition, following the tutorial, I wrote my verified number in the field "callerNumber" of the fields of the server make-call.js and place-call.js

I'm very new with the VoIP services so I'm trying to understand how to implement ad app-to-phone service (tried twilio and vonage)

I am trying to implement a call feature in my xamarin forms app using Twilio. I am able to call by providing From and To numbers using this API of Twilio. But the above call is happening via Twilio, I need to make a call via the internet (App to App). Is there any way to do this using Twilio?

Also is there a way to send a voice clip if the call is not answered? And any way to list out all the voices? I am able to list out SMS and call logs, but couldn't find a way to list the voices. I am using c# codes.

I'm looking for a way to generate a Conference resource within the Twilio system before adding anyone to that conference.

The official recommended way to start a Conference is by returning TwilXML in response to a Twilio callback. This can either be done in response to someone calling a Twilio number or, in a somewhat indirect way, by making a call and returning TwilXML which will connect the person to a conference once they pick up. All of the APIs to modify conferences use the ConferenceSID as the handle to decide what conference to change. The problem with both of these methods is that they do not give you the ConferenceSID until you receive a callback.

Unfortunately callbacks do not contain any identifying information about who generated them. They do have a ConferenceSID (identifying the conference), and a CallSID (uniquely identifying the call connecting the caller to the conference). When you get your first callback, there appears to be no way to be able to match either of those identifiers. If you start multiple conferences and get two callbacks with different ConferenceSIDs and different CallSIDs, it is inconvenient to tell which conference is generating which callback.

That's why it would be easiest to create a conference resource and then use the versatile add participant call. This would simplify the entire backend flow for using conferences by starting with the ConferenceSID and going from there.

P.s. To head off other suggestions - there are ways around this. You can specify different callback URLs for different conferences. You can specify different friendlyNames for different participants which you can match in your backend. It's totally possible to work with, but I would like something cleaner, which would require making conferences before anyone is called.

I found this: https://github.com/AndrewGaspar/cmake-cargo but couldn't make it work

Anyway, if I were to use a Makefile instead of CMake, I'd simply create a rule that watches for the .rs files to change and recompile.

I couldn't find a solution for calling Cargo from Cmake (not the other way around) so I'm opening one here.

How can I make my CMakeLists.txt watch for .rs file changes and recompile by calling cargo build?

I need to freeze (stop) the preview when user initiates taking the photo. I've searched around and I've found this SO post that mentions unbinding Preview UseCase. I've tried that and at first it works correctly on Android 9+, but on lower Android I receive following error in Logcat and picture is not taken.

I have a function where I am using parse-integer and prompt-read together. However, I need one of these integers to be a float. When I change parse-integer to parse-float it no longer works. Here is the function:
