In GitHub, is there a way to see all (recent) commits on all branches?

https://stackoverflow.com/questions/33926874/in-github-is-there-a-way-to-see-all-recent-commits-on-all-branches/63925422#63925422

Click "Code" (left-most tab) on the main page for the repository. Under those 4 buttons ("master", "Go to file", "Add file", "Code") there is a blue rectangle. At the right end of that is a clock icon and a number. If the viewport of your browser is wide enough it even includes (hurrah) the word "commits". This is a link. Click and ENJOY!!!

Thanks for finding this! This is definitely the right answer. The Commits link feels so hidden in plain sight and really should be up with the other primary buttons (master, Go to File, etc). If you're having trouble finding it, ctrl+f for "commits" on the "Code" tab.

Agile Story Point Estimation

T-Shirt Sizing

T-shirt Sizing is one of the Story points sizing technique to estimate user story usually used in agile projects. It's a relative Estimation Technique.

Rather than using a number of planning pokers, here, Items are classified into t-shirt sizes: XS, S, M, L, XL.

The term originates from the way T-shirt sizes are indicated in the US. Rather than having T-shirts in sizes 4, 5, 6 etc, there are just a few sizes: Small (S), Medium (M), Large (L) and Extra Large (XL) and so on.

Planning Poker

Each team member comes up with the size of the story related to the reference user story.
Team members show the card to everyone.

Maven Wrapper - What, Why & How

Maven Wrapper- Why ?

This feature of Maven is borrowed from Gradle

We want to use different version of Maven in my Project than what is installed at my Computer, So we can Use Maven Wrapper
We use it to encapsulate our source code and Maven build system.
This lets other developers build our code without having Maven pre-installed.
We don’t have to worry about installing the right version of Maven on the CI servers anymore!

https://github.com/takari/maven-wrapper

https://reflectoring.io/maven-wrapper/
https://www.baeldung.com/maven-wrapper

2. Setting Up the Maven Wrapper

2.1. Plugin

mvn -N io.takari:maven:wrapper

We can also specify the version of Maven:

mvn -N io.takari:maven:wrapper -Dmaven=3.5.2

The option -N means –non-recursive so that the wrapper will only be applied to the main project of the current directory, not in any submodules.

After executing the goal, we'll have more files and directories in the project:

mvnw: it's an executable Unix shell script used in place of a fully installed Maven
mvnw.cmd: it's the Batch version of the above script
mvn: the hidden folder that holds the Maven Wrapper Java library and its properties file

2.2. Manual

With a manual approach, we can copy files and folders seen above from another project to the main folder of the current project.

Afterwards, we need to specify the version of Maven to use in the wrapper properties file located in .mvn/wrapper/maven-wrapper.properties file

Usage without Binary JAR

By default, the Maven Wrapper JAR archive is added to the using project as small binary file .mvn/wrapper/maven-wrapper.jar. It is used to bootstrap the download and invocation of Maven from the wrapper shell scripts.

If your project is not allowed to contain binary files like this, you can configure your version control system to exclude checkin/commit of the wrapper jar.

If the JAR is not found to be available by the scripts they will attempt to download the file from the URL specified in .mvn/wrapper/maven-wrapper.properties under wrapperUrl and put it in place. The download is attempted via curl, wget and, as last resort, by compiling the ./mvn/wrapper/MavenWrapperDownloader.java file and executing the resulting class.

distributionUrl=https://repo.maven.apache.org/maven2/org/apache/maven/apache-maven/3.5.2/apache-maven-3.5.2-bin.zip
wrapperUrl=https://repo.maven.apache.org/maven2/io/takari/maven-wrapper/0.5.6/maven-wrapper-0.5.6.jar
