I'm trying to push my first docker image to ECR. I've followed the steps provided by AWS and things seem to be going smoothly until the final push which immediately times out. Specifically, I pass my aws ecr credentials to docker and get a "login succeeded" message. I then tag the image which also works. pushing to the ecr repo I get no error message, just the following:...

I figured out my issue. I wasn't using the correct credentials. I had a personal AWS account as my default credentials and needed to add my work profile to my credentials.
If you have multiple aws profiles, you can mention the profile name at the docker login as below (assuming you have done
aws configure --profile someprofile at earlier day),
First off, I have no idea how to decently phrase the question, so this is up for suggestions.

It all makes sense and has a simple pattern besides
() -> null being a
Callable I think. The
Runnable is clearly different from the
Callable as it has no input and output values. The difference between
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
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
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.

It is a bug, you can downgrade using:

I am reading this book by Fedor Pikus and he has some very very interesting examples which for me were a surprise.
Particularly this benchmark caught me, where the only difference is that in one of them we use || in if and in another we use |.

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).
I know that compiler is usually the last thing to blame for bugs in a code, but I do not see any other explanation for the following behaviour of the following C++ code (distilled down from an actual project):...

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:

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.

Just stumbled upon the same thing (strange windows upon attempting to refactor some code after updating to Arctic Fox). After a lot of searching around the options/menus/internet this fixed it for me:
File > Settings... > Editor > Code Editing
Refactorings > Specify refactoring options:
In modal dialogs
Fingers crossed refactoring works.
Further step: Restart Android Studio
