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.

EDIT
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),

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.

It is a bug, you can downgrade using:

pip install "pip<22"

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:

Update the Rust to satisfy the new edition 2021.

rustup default nightly && rustup update

Thanks to @ken. Yes, you can use the stable channel too!

But I love nightly personally.

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:

Navigate to:

File > Settings... > Editor > Code Editing

under

Refactorings > Specify refactoring options:

select

In modal dialogs

Press OK.

Fingers crossed refactoring works.

🤞

Further step: Restart Android Studio

Note: When referring to documentation and source code, I provide links to an unofficial GitHub mirror of R's official Subversion repository. The links are bound to commit 97b6424 in the GitHub repo, which maps to revision 81461 in the Subversion repo (the latest at the time of this edit).

substitute is a "special" whose arguments are not evaluated (doc).

You can use a guard:
