I am using Mjsip to build a softphone. I have integrated multiple codecs with it. For test purpose when I make call to another client which is a Portsip 2.0 (G729, ULAW, ALAW, GSM, ILBC) I get an 488 error (Not accepted here). I have integrated G729, ULAW, ALAW, ILBC with my project and codec precedence is g729:ulaw:alaw:ilbc. But after compiling the project if i initiate a call from portsip to my phone. It rings. Then If I call back from my phone it doesn't show any error. It always show error if I tried to call from my softphone after compiling.

I am using firebase v4 to push notifications to android devices. When the Send method of the instance of messaging.Client fails, I only get a string error value and I wonder if this error string is localized. If not, I could compare it against e.g. "Requested entity was not found." to detect devices that have uninstalled my app. Is this string always plain english or does this depend on the locale the app is running under? Or does this error string come from the server, so I can never be sure if it stays the same?
What other options do I have to properly detect such an error, even if my golang binary runs on computer systems with any locale or language? I am running my golang binary on windows.
Any help or insights appreciated,

In general, all error messages from Firebase SDKs are in English only. They are generally not suitable for display or comparison in an app. You should instead use the provided error codes (which will not vary) in the error or exception object to determine what exactly went wrong.
We have an NServiceBus 6 environment with a number of services that send files between each other using DataBusProperty over a custom SqlDataBus : IDataBus.
This works fine on NSB6 using the built in JSON serializer, but is now broken after we moved to NSB7 and the NewtonsoftSerializer.
Removing DataBusProperty from our classes and just using byte[] works fine. We also tried changing the DataBus to FileShareDataBus but got the same exception:
NServiceBus.MessageDeserializationException: An error occurred while attempting to extract logical messages from incoming physical message c7b5cd47-c1b7-4610-9f6c-aa7800cc9b64 --->
Newtonsoft.Json.JsonReaderException: Error reading bytes. Unexpected token: StartObject. Path 'Data.Key', line 1, position 68.
This fails even if a service is sending messages to itself. Also we can see the files written to the file store, whether on Sql or File Share, so they're serializing fine.
An example payload from the error queue is
{"ExecutionId":"1db85105-a71c-4b29-87da-9b7ae6518c1c","Data":{"Key":"2019-06-26_13\\6a2b63c7-12b0-46dd-8b92-f1fc743d27c1","HasValue":true}}
How can we get this to deserialize in NSB7+NewtonsoftSerializer when it works fine in NSB6+JsonSerializer?
Thanks
I just spent about 8 hours trying to figure out what was going on, and realized, that for whatever reason, NSB7 wants a paramaterless constructor and settable properties. I am going back to Particular to see if this change is expected, but I expect we will have to adjust all of our message classes to fit that paradigm.
Although data bus properties should work there is also an alternative to data bus properties which is using stream attachments via send options:
https://docs.particular.net/nservicebus/messaging/attachments-sql
Depending on the use case using Streams might be a more efficient approach.
Failed biometric(fingerprint) scan attempts are handled by OnAuthenticationFailed() callback of BiometricPrompt.AuthenticationCallback class.
The behavior I noticed is, it lets the user attempt 5 invalid fingerprint scans (each time the fail callback is invoked) and then the prompt dismisses. Within the next 30 secs, if we try to re-build a BiometricPrompt instance and try to authenticate, it does not show the prompt which I think is the default behavior of BiometricPrompt.
Is there anyway to check if the biometric scanner is available and initialised if the user attempts to re-invoke biometric prompt within the said 30secs?
How can I handle that use case?
xamarin android BiometricPrompt.AuthenticationCallback does not have an override method "onAuthenticationError" to handle error callbacks and thus I'm unable to handle error code "BIOMETRIC_ERROR_TIMEOUT".
If someone has a solution for this, please do let me know your resolution.
I believe that BiometricPrompt is not fully ported to Xamarin yet...
I'm still looking for a source that can double check this info for me, but I haven't found it either.
I'm trying to create a hologram that is shared among multiple Hololenses by following Microsoft's Holograms 240 tutorial at https://developer.microsoft.com/en-us/windows/holographic/holograms_240
The network connection is working fine, and I have all the correct permissions in my project settings. The issue is that aside from a rare occurence, the call to WorldAnchorTransferBatch.ExportAsync() will fail with a SerializationCompletionReason.UnknownError and print out "Failed to world lock serialization failed"
I haven't been able to find any information about this error in my searching. Does anyone know what the cause of this could be?
I compiled Xorg for a custom Linux I'm building for an ARM device. I'm trying to run OpenGL applications using EGL with the Qt framework but I get these errors:
X Error: BadRequest (invalid request code or no such operation) 1
Extension: 198 (Uknown extension)
Minor opcode: 0 (Unknown request)
Resource id: 0x600082
and this:
X Error: BadRequest (invalid request code or no such operation) 1
Extension: 160 (Uknown extension)
Minor opcode: 0 (Unknown request)
Resource id: 0x600082
repeated many times. What does this mean? How can I investigate on what is wrong? Something is drawn on the screen correctly with OpenGL, but after that everything is screwed up.
It seems like something is missing in my Xorg, but I can't find anything about these extensions 198 and 160. How does one figure out what is missing or anyway what is wrong? Do I have to compile anything specific to be able to run OpenGL applications for X11?
Thanks!
The extension numbers are dynamically assigned by the X server based on the extensions supported in a particular codebase and enabled in a particular configuration. To get a list of the extension name to number mappings on the current display, you can run xdpyinfo -queryExtensions | grep opcode — the opcode value listed for each one should match the extension number in Xlib error reports. If none of the extensions match, then it seems likely you've got memory corruption or are calling an extension without first verifying it's currently available in the X server.
