            Using MassTransit with Azure Service Bus, I would suggest taking the message routing burden away from the publisher, and moving it to the consumer. By configuring the receive endpoint and using a subscription filter each instance would add its own subscription and use a message header to filter published messages.

            On the publisher, a message header would be added:

            How to thread a generator
            Asked 2021-Jun-15 at 16:02

And I have a consumer that all of the CPU to process the data yielded by generator. It does not consume much of other resources. Is it possible to interleave these tasks using threads?

            Not yet no. Here is a specs issue discussing this very matter, and it is something a lot of actors would like to see, so there is hope it comes, one day.

            Note that there is an AudioWorklet API available, which will create its own Worklet (which also works in a parallel thread), but you still need to instantiate it from the UI thread, and you don't have access to everything that can be done in an AudioContext. Still, it may suit your needs.

            Also, note that it might be possible to do the computing you have to do in a Worker already, by transferring ArrayBuffers from your UI thread to the Worker's one, or by using SharedArrayBuffers.

            Deserializing redis's Value in Rust (FromRedisValue)
            Asked 2021-Jun-15 at 09:55

            I'm implementing a simple task queue using redis in Rust, but am struggling to deserialize the returned values from redis into my custom types.

            In total I thought of 3 approches:

            1. Deserializing using serde-redis
            2. Manually implementing the FromRedisValue trait
            3. Serializing to String using serde-json > sending as string > then deserializing from string

            The 3rd approach worked but feels artificial. I'd like to figure out either 1 or 2, both of which I'm failing at.

            Redis doesn't define structured serialization formats. It mostly store strings and integers. So you have to choose or define your format for your struct.

            A popular one is JSON, as you noticed, but if you just want to (de)serialize simple pairs of (id, description), it's not very readable nor convenient.

            In such a case, you can define your own format, for example the id and the description with a dash in between:

            How python multithreaded program can run on different Cores of CPU simultaneously despite of having GIL
            Asked 2021-Jun-15 at 08:23

            In this video, he shows how multithreading runs on physical(Intel or AMD) processor cores.

            https://youtu.be/ecKWiaHCEKs

            and

            is python capable of running on multiple cores?

            All these links basically say:
            Python threads cannot take advantage of many physical cores. This is due to an internal implementation detail called the GIL (global interpreter lock) and if we want to utilize multiple physical cores of the CPU we must use true parallel multiprocessing module

            https://docs.python.org/3/library/math.html

            The math module consists mostly of thin wrappers around the platform C math library functions.

            While python itself can only execute a single instruction at a time, a low level c function that is called by python does not have this limitation.
            So it's not python that is using multiple cores but your system's well optimized math library that is wrapped by python's math module.

            That basically answers both your questions.

            Regarding the usefulness of multiprocessing: It is still useful for those cases, where you're trying to parallelize pure python code or code that does not call libraries that already use multiple cores. However, it comes with inter process communication (IPC) overhead that may or may not be larger than the performance gain that you get from using multiple cores. Tuning IPC is therefore often crucial for multiprocessing in python.
