Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Performance and memory impact of the @Singleton annotation in Dagger
There used to be a thing called "releasable references" which was that. It was removed, though: https://github.com/google/dagger/issues/1117

Dependency injection with AWS Lambdas in java
As said in the title, we will focus on the dependency inversion principle and one of its application : dependency injection. For production-ready applications, it would be better to rely on a framework and not implement its own container. For it, the java ecosystem have 3 frameworks available : Spring, Guice and Dagger.

Refactoring our Dependency Injection using Anvil
At Reddit, we use Dagger 2 for handling dependency injection (DI) in our Android application. As we’ve scaled the application over the years, we’ve accrued a bit of technical debt in how we have approached this problem.

Multiplatform dependency injection libraries equivalent to Dagger/Anvil
I'm currently using Dagger and Anvil for my DI needs. It's been working really well, especially around what Anvil permits in terms of multibindings defined on the type declaration rather than in a module. For example:

Hexagonal Architecture/Ports And Adapters: Clarifying Key Concepts Using Go
Historically, Ports and Adapters was born in the context where Dependency Inversion Principle (DIP) was getting hot, back in the beginning of the 2000’s. DIP was getting more present on development day to day, and an example of a framework that was a pioneer in such topic is Google Guice.

Inversion of Control Containers and the Dependency Injection Pattern (2004)
“There are many advantages to using dependency injection, but doing so manually often leads to a large amount of boilerplate code to be written. Guice is a framework that makes it possible to write code that uses dependency injection without the hassle of writing much of that boilerplate code”
This is a common misconception. Guice’s docs delineate between dependency injection as a pattern and Guice as a framework that supports that pattern.
- How to dependency injection
-
Why dependency injection?
You can (and it's very normal to) use that with new. Dependency injection frameworks (like guice) let you skip passing long parameter lists to constructor arguments like you mention. But you don't really NEED that. They also will solve circular dependency issues and some other things, although a strong argument could be made that you should simply restructure your code so that those issues don't exist.

Bob Lee, Former CTO Square, Creator of CashApp, Stabbed to Death in SF
Bob was a nice guy. We had an overlapping tenure at Google in the 2000s. He was one of the original authors of the Guice dependency injection framework: https://github.com/google/guice. When I was earning Java readability at Google, I was fortunate to have had him assigned as a reviewer. Huge loss; he left a very positive impression on me.

Bob Lee Was Killed
He was fairly well known figure in the Java world. RIP.

Handling two contexts
Usually each context has a different scope and lifetime associated with it. Here, it sounds like there are two distinct scopes: server and request (cf. how Guice models scopes: https://github.com/google/guice/wiki/Scopes). It is rarely sensible to merge the scopes or contexts together. If we think about a context, it contains several things:
