For version 2.6.0, neither the ExampleDTLSClient nor the ExampleDTLSServer comes "out of the box" with CID enabled (but I will change that for 3.0 :-) ).

If you want to see that "out of the box" use the "cf-secure" demo. Start the client with "CID:0" for "support CID", and the server with "CID:6" to use a 6 bytes CID.

To enable CID for ExampleDTLSClient and ExampleDTLSServer, add to the DtlsConfigurationBuilder a

I continued researching on my own and Java 15 is the problem. If anyone has the same problem as i had just switch to Java 11 and run the build as described. It worked fine for me. If you have any other problems I suggest that you also post your questions, concerning leshan lwm2m, on https://github.com/eclipse/leshan/issues.

EDIT: You can also do it with Java 15. You have to change the pom.xml document. Change in line 456 the version from 4.0.0 to 5.1.1 .

Apply the & to the boolean tests, before indexing:

I made a plunker with a working solution: https://plnkr.co/edit/QyAglTqoVx8k5RhZbenV?p=preview

Yeah, it needs put NaamOfAtoom(AtoomNum) inside that berekenen() function to fill that Atoomnaam variable, and change the switch.

Basically, when you did that switch, the cases are numbers, but AtoomNum is a string (you can type letter also), so it didn't entered any case options. So was equivalent to 12 === '12' returning false. switch is strict comparing === instead of only ==.

Adding a parseInt(number) solved switch part.

Use an alias for the properties that have a dash - :

atomic-number is not a valid variable name in javascript.

doOnRequest() will fire whenever the subscriber requests new elements from upstream (along with the number of elements requested as its parameter.) Since you've limited the rate to 2, you'd expect this to be called with 2 as a parameter every time, which it's doing.

Well, actually it does, but not how you expect it to. Lazy doesn't necessarily mean "one at a time", it just means it will evaluate batches as they're called for, rather than always evaluating the whole Flux in one go.

Specifically, note that the limitRate() method doesn't apply automatically to the iterator in the same way - it has a separate batch size that you have to specify as a parameter to the toIterable() method.

You can specify a prefetch rate and a batch size of 1, and then you're likely to only get 4 elements generated (rather than 3, as it'll always have at least one additional element ready for the following next() call):

Yes, reactor netty supports keep-alive, connection reuse, and connection pooling.

Note that .flatMap is a async operation that processes the inner streams in parallel. Therefore, when you call group.flatMap(... the inner requests will be executed in parallel. And since they are executed in parallel, multiple connections will need to be established.

If you want to execute requests to the same host sequentially, change your example to use group.concatMap instead of .flatMap.

If you want to still execute them in parallel, but limit the number of active requests to an individual host, then change your example to use one of the overloaded versions of .flatMap that takes a concurrency parameter.

Also, since you are using HttpClient.create(), your example uses the default global http connection pool. If you want more control over connection pooling, you can specify a different ConnectionProvider via HttpClient.create(ConnectionProvider).

You have char** packet which is a pointer to a pointer to some chars.

You then treat that as int * which is a pointer to some ints.

You then overwrite the first int - so you're writing into 'dest' itself and not what it points to. And since you write more after that, you're corrupting the stack.

The good news is you were really, really close. The bad news is the "really really close" part -- it only takes one subtle error to torpedo your code.

First the general discussion. While there is nothing wrong with using a pointer-to-pointer-to-Element, you are missing the benefits of using C++ and the automatic memory handling offered by . That said, it is good to know how to handle both.

Your error is:
