I'm working with a streaming pipeline which has a protobuf data source in pubsub. I wish to parse this protobuf into a python dict because the data sink requires the input to be a collection of dicts. I had developed a Protobuf Parser successfully by initializing the protobuf message in process function of DoFn.

However, I wanted to know, is it possible to make a generic ProtobufParser DoFn on Beam? A generic DoFn is useful from the engineering perspective to avoid re-implementing existing functions and enabling code reuse. In Java, I know that we're able to use generics hence implementing this generic ProtobufParser in Java is relatively easy. Since Python functions are first-class objects, I was thinking whether it's possible to pass a Protobuf schema class (not the message instance object) into a DoFn. I tried to do this, however I kept failing.

Below is my current successful protobuf parser. The protobuf message is initialized inside process function.

I'm currently new to using Apache Beam in Python with Dataflow runner. I'm interested in creating a batch pipeline that publishes to Google Cloud PubSub, I had tinkered with Beam Python APIs and found a solution. However, during my explorations, I encountered some interesting problems which made me curious.

Currently, my successful beam pipeline for publishing data in batch manner from GCS looks like this:

May I know how to use this nuget package "IS_nRF24l01p" . I have figured out the command and variable to be declared so that the device can use the NRF24L01p module. But as a beginner in coding, I dont really familiar with the syntax and so on. I just want to do a simple "Hello World". But I am stuck at the initialization step. I follow some tutorial from this website https://technoblogiot.wordpress.com/2016/12/27/raspberry-pi-et-le-controller-driver/ But it is in Vb. But I have to code in C#. Can anyone teach me on how to do the step like this? Declare the settings for nrf24L01. Thanks in advance.

Can someone explain why inside Angular's DataPipe there is this expression: value !== value. In which case this does it make sense?

I can't seem to find why scala packages are being "thought of" by maven as a member of package org.apache.kafka.streams.scala. I usually use sbt but I have to use maven on this one. Any help would be appreciated.

I'm trying to write down 6809 assembly in EBNF to write a tree-sitter parser.

I'm stuck on one certain production. In 6809 assembly, you can use a register as an operand and additionally de- or increment it:

I’m building a real time chat application with C# and ffmpeg.exe. My requirement is to get a memory stream from Microsoft Speech API and feed it to ffmpeg process in real time. I can take a memory stream from Microsoft Speech API. I’m using following code to create the memory stream.

I have an application where I need to perform a fairly expensive calculation based on the actual width and height of a control. I have bound ActualWidth and ActualHeight of this control to properties in my code. I find that Actualheight is being changed in small steps. I assume this is because of the Layout Engine.

I am struggling to get this simple cascading program to run. For some reason it does nothing. Least I would expect it to print the records. Any help would be appreciated.
