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.

Inversion of Control Containers and the Dependency Injection Pattern (2004)
> Dependency injection has always been such a bad name for the concept. It is just passing dependencys as arguments.
No.
Dependency Injection means using tooling to "inject" the dependency, instead of passing an explicit argument.
https://github.com/google/guice
> Think of Guice's `@Inject` as the new `new`.
Like many architecutral design patterns, toy examples don't illustrate the concept well. It's used for doing things like switching a large service-based system from using external databases and remote services for production, to in-memory everything for testing.
“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.

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:
-
Dependency Injection in Scala - cake pattern
using libraries from java world, such as Guice;
-
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.

"My Reaction to Dr. Stroustrup’s Recent Memory Safety Comments"
And it doesn't really matter whether you have created circular reference structure of whether you have messed up your binding and now objects which was supposed to disappear after one request is only doing that when all database connections are quiescent (which happens easily in testing, but may not happen for days in production).

About design patterns: Dependency Injection
The following section is an example of injecting our service using Guice, a dependency injection framework for Java made by Google. The concept is to reference bindings of every component you can inject in your program, so that the library can generate a class of any type, automatically.

Spring Boot Monitoring with Open-Source Tools
Manual instrumentation allows you to define your Spans within the code itself rather than relying on automatic instrumentation finding the entry point for a trace. Manual instrumentation is especially helpful for applications that don’t use an application server such as Tomcat, JBoss, or Jetty.

Issue with chatgpy
99% is a huge exaggeration. Two essential deployment tools off the top of my head: https://tomcat.apache.org/ https://docs.jboss.org/author/display/AS71/Developer%20Guide.html

7 years with Vaadin in production. Do we still enjoy it?
Do we still enjoy it? We are running many Vaadin apps in production since that first one. If there are not any specific requirements we use a “modular monolith” concept, which fits our stack best. We pack applications as WAR and deploy them under Apache Tomcat. And yes, we enjoy the development process. It’s very straightforward and Vaadin and SpringBoot fit together well.

TIBCO Jaspersoft Studio tutorial: Creating templates and integration with JasperReports Server
JasperReports Server Community requires a Java application server and a database to create a repository in order to work properly. After downloading JRS, the installation process can install Tomcat server and PostgreSQL database automatically for us and the services will run depending on the Jasper server. It's also possible to connect JRS to services already installed on the server. Moreover, while the free version supports the MySQL server, with the paid version you can also use commercial databases, for example, ORACLE Database, as a data repository.

Show HN: Open-source non-blocking NIO Java HTTP Server
Regarding the venerable Tomcat, they [somewhat] recently added support for Unix domain sockets.
* https://github.com/apache/tomcat/pull/402
* https://github.com/apache/tomcat/pull/532
We fronted the server with haproxy LTS. Our initial testing showed roughly and order of magnitude [10x] increase in the number of requests the server could handle.
It's not completely plug-and-play; we still had a write a custom valve to set the request remote ip address and some other TCPish stuff, but nevertheless the capacity far outstripped our need for the technology.

The 12-Factor App Building Methodology
Example: Little Johnny was developing a Java web app and thinking about how he would configure Tomcat to listen to requests and redirect the data into his app... until he remembered this would violate Factor 7! Instead, he decided to declare Jetty as a dependency, keeping the HTTP service inside the app instead of configuring an external web server and then injecting its functionalities. Now, whenever he wants to instantiate another server for this app, all he has to do is installing dependencies and running the app, isn't it convenient?

Team 'print to console' assemble
Apache has multiple "server" projects- Apache HTTP Server is an a server program written in C, while Apache Tomcat is a server program written in Java.

Non Spring users what are you using ??
Multiple applications in the same JVM? Wildfly, Tomcat, Jetty.

Packaging and deploying Spring Boot applications as WAR files
Download Apache Tomcat from the project website. Make sure to download the correct version, depending on the Java and Servlet API versions that your application uses. For example, in the case of Vaadin applications, download Apache Tomcat version 9.
