This repository contains Go/Golang client for Emitter (see also on Emitter GitHub). Emitter is an open-source real-time communication service for connecting online devices. At its core, emitter.io is a distributed, scalable and fault-tolerant publish-subscribe messaging platform based on MQTT protocol and featuring message storage. This library provides a nicer MQTT interface fine-tuned and extended with specific features provided by Emitter. The code uses the Eclipse Paho MQTT Go Client for handling all the network communication and MQTT protocol, and is released under the same license (EPL v1).

            How does Java know which overloaded method to call with lambda expressions? (Supplier, Consumer, Callable, ...)
            Asked 2022-Mar-17 at 08:29

            First off, I have no idea how to decently phrase the question, so this is up for suggestions.

            Lets say we have following overloaded methods:

            ...

            ANSWER

            Answered 2022-Mar-17 at 08:29

            It all makes sense and has a simple pattern besides () -> null being a Callable I think. The Runnable is clearly different from the Supplier/Callable as it has no input and output values. The difference between Callable and Supplier is that with the Callable you have to handle exceptions.

            The reason that () -> null is a Callable without an exception is the return type of your definition Callable. It requires you to return the reference to some object. The only possible reference to return for Void is null. This means that the lambda () -> null is exactly what your definition demands. It would also work for your Supplier example if you would remove the Callable definition. However, it uses Callable over Supplier as the Callable has the exact type.

            Callable is chosen over Supplier as it is more specific (as a comment already suggested). The Java Docs state that it chooses the most specific type if possible:

            Type inference is a Java compiler's ability to look at each method invocation and corresponding declaration to determine the type argument (or arguments) that make the invocation applicable. The inference algorithm determines the types of the arguments and, if available, the type that the result is being assigned, or returned. Finally, the inference algorithm tries to find the most specific type that works with all of the arguments.

            Particularly this benchmark caught me, where the only difference is that in one of them we use || in if and in another we use |.

            Answered 2022-Feb-08 at 19:57

            Code readability, short-circuiting and it is not guaranteed that Ord will always outperform a || operand. Computer systems are more complicated than expected, even though they are man-made.

            There was a case where a for loop with a much more complicated condition ran faster on an IBM. The CPU didn't cool and thus instructions were executed faster, that was a possible reason. What I am trying to say, focus on other areas to improve code than fighting small-cases which will differ depending on the CPU and the boolean evaluation (compiler optimizations).

            The evaluation order of A = B was not specified before c++17, after c++17 B is guaranteed to be evaluated before A, see https://en.cppreference.com/w/cpp/language/eval_order rule 20.

            The behaviour of valMap[val] = valMap.size(); is therefore unspecified in c++14, you should use:

            Android Studio strange code sub-windows after upgrade to Arctic Fox (2020.3.1)
            Asked 2022-Jan-14 at 09:18

            After Android Studio upgraded itself to version Arctic Fox, I now get these strange sub-windows in my code editor that I can't get rid of. If I click in either of the 2 sub-windows (a one-line window at the top or a 5-line window underneath it (see pic below), it scrolls to the code in question and the sub-windows disappear. But as soon as I navigate away from that code, these sub-windows mysteriously reappear. I can't figure out how to get rid of this.

            I restarted Studio and it seemed to go away. Then I refactored a piece of code (Extract to Method Ctrl+Alt+M) and then these windows appeared again. Sometimes these windows appear on a 2nd monitor instead of on top of the code area on the monitor with Android Studio. But eventually they end up back on top of my code editor window.

            I have searched hi and low for what this is. Studio help, new features, blog, etc. I am sure that I am just using the wrong terminology to find the answer, so hoping someone else knows.

            select

            In modal dialogs

            Press OK.

            Fingers crossed refactoring works.
