E-Serial | - Serial port tool | Wrapper library

I have a relatively simple case where:

1. My program will be receiving updates via Websockets, and will be using these updates to update it's local state. These updates will be very small (usually < 1-1000 bytes JSON so < 1ms to de-serialize) but will be very frequent (up to ~1000/s).
2. At the same time, the program will be reading/evaluating from this local state and outputs its results.
3. Both of these tasks should run in parallel and will run for the duration for the program, i.e. never stop.
4. Local state size is relatively small, so memory usage isn't a big concern.

The tricky part is that updates need to happen "atomically", so that it does not read from a local state that has for example, written only half of an update. The state is not constrained to using primitives and could contain arbitrary classes AFAICT atm, so I cannot solve it by something simple like using Interlocked atomic operations. I plan on running each task on its own thread, so a total of two threads in this case.

To achieve this goal I thought to use a double buffer technique, where:

1. It keeps two copies of the state so one can be read from while the other is being written to.
2. The threads could communicate which copy they are using by using a lock. i.e. Writer thread locks copy when writing to it; reader thread requests access to lock after it's done with current copy; writer thread sees that reader thread is using it so it switches to other copy.
3. Writing thread keeps track of state updates it's done on the current copy so when it switches to the other copy it can "catch up".

That's the general gist of the idea, but the actual implementation will be a bit different of course.

I've tried to lookup whether this is a common solution but couldn't really find much info, so it's got me wondering things like:

1. Is it viable, or am I missing something?
2. Is there a better approach?
3. Is it a common solution? If so what's it commonly referred to as?
4. (bonus) Is there a good resource I could read up on for topics related to this?

Pretty much I feel I've run into a dead-end where I cannot find (because I don't know what to search for) much more resources and info to see if this approach is "good". I plan on writing this in .NET C#, but I assume the techniques and solutions could translate to any language. All insights appreciated.

I am trying to de-serialize json in a parent class. One of my items is a Map of a Map, which I'd like to de-serialize into a Types class. I am struggling with parsing this because of the nested map in a map and I'm unclear on the proper syntax. At the end of the day I want a List in the parent class. The items within the types json block are dynamic, so there could be a type of critical, notice, etc. with varying descriptions.

Json sample:

I am trying to write my own custom serialize and de-serialize for an object of my application. I know there are plenty of libraries like boost serialize etc. available for ready use but I wanted to learn this serialize and de-serialize hence this effort.

Problem occurs when I try to de-serialize(using std::wifstream) the object I had serialized(using std::wofstream). Not able to read even one class member correctly. First 3 members I am trying to de-serialize are bool, but they read incorrect values from the file stream. Can someone please suggest any pointers as to what could be the problem here. Thanks for your time.

Typedefs in application:

I'm working to integrate Spring Cloud Streams with Kafka binder. Aim is my app consumes json from the topic and deserialize it to the Java object. I am using the functional style approach instead of imperative. My code is working with well-structured json inputs.

On the other hand, when I send the invalid json, I want the error logging method to be triggered. This works in some test cases and does not work in another. My application deserializes json even if it is invalid and triggers the method which contains logic, not the error logging one.

I could not solve the problem why the framework deserialize some unstructured json input.

I am getting following error while using kafka-streams.

I have a JAVA springboot project, pushing avro messages in kafka. During my development, using a windows PC, all my messages in kafka appeared right with all special character (é, à, ...)

Using the following serializer :

I've got incoming json arrays that I need to de-serialize into a class. The class is basically a two property class but the incoming json arrays may have different Key names but they will always be in a keyname/value pair.

Is there a way to do this without having to create a different class for each variation? My class:

I'm converting some code that originally used the json++ library to now use rapidJSON. The code serializes and de-serializes various objects using json files. In json++, it looks something like this:

I have configured following Kafka properties for my spring boot based library bundled inside a lib directory of an EAR deployed to Wildfly. I am able to start the spring components successfully by loading the porperty file from classpath (WEB-INF/classes)
