4 min readTo make a commit in Git, you first need to stage the changes you want to include in the commit. You can do this by using the "git add" command followed by the file or files you want to stage. Once the changes are staged, you can create a commit by using the "git commit" command followed by a message that describes the changes you are committing. This message should be concise but informative.

3 min readTo install the "locate" command on Vagrant, you can simply run the following command in the terminal:sudo apt-get update sudo apt-get install mlocateOnce the installation is complete, you can use the "locate" command to quickly search for files and directories on your Vagrant machine. Just type "locate" followed by the name of the file or directory you are looking for, and the command will return the path to its location on the system.

3 min readTo get the value of a variable in Groovy, you simply need to refer to the variable by its name. For example, if you have a variable named "myVariable", you can access its value by simply typing "myVariable". This will return the current value stored in the variable. Additionally, you can use the println() function to print out the value of a variable to the console for debugging or output purposes.

3 min readTo split a list by a keyword in Elixir, you can use the Enum.split_with/2 function. This function takes two arguments: the list you want to split and a function that determines whether an element should be split. The function should return a tuple where the first element is a boolean indicating if the element should be split and the second element is the value to split by.

3 min readWhen merging branches in git, you may want to ignore specific files to prevent conflicts or unwanted changes. To do this, you can use the git merge command with the --no-commit option to stop before the actual commit is made. Then, reset the changes for the specific files using git checkout -- command. Finally, you can continue with the merge by using git commit -m "Merge branch" command. This way, you can exclude specific files from being merged while combining branches in git.
-
3 min readTo remove a forwarded port in Vagrant, you can modify the Vagrantfile of your project. Open the Vagrantfile in a text editor and find the line that specifies the forwarding of the port you want to remove.Simply remove or comment out that line, and then save the file. After making this change, you will need to reload the Vagrant environment by running the command "vagrant reload" in your terminal.

4 min readIn Elixir, a double loop can be implemented using nested Enum.each functions or by using a combination of Enum.map and Enum.reduce functions.You can iterate over two lists simultaneously by using Enum.zip function and then apply a function to each pair of elements.Another way to implement a double loop in Elixir is by using a recursive function that iterates over each element in one list and then applies a function to each element in the second list.

5 min readTo get ignored files with git, you can use the command git status --ignored. This will show you a list of files that are being ignored by git based on your .gitignore rules. These ignored files will not be tracked or included in your version control system. This command can help you ensure that sensitive or unnecessary files are not being accidentally included in your git repository.[rating:ac02108b-fd50-45de-b562-c8e4d0f6fbc8]What is the role of the .git/info/exclude file?The .

5 min readTo define network settings with Vagrant, you can use the config.vm.network configuration option in your Vagrantfile. This option allows you to specify the network settings for your virtual machine, such as the IP address, private or public network, port forwarding, and more.For example, to define a private network with a static IP address for your virtual machine, you can use the following code in your Vagrantfile: Vagrant.configure("2") do |config| config.vm.
-
4 min readTo get the minimum and maximum values from a group array in Groovy, you can use the min() and max() methods provided by the Groovy Collections API. These methods can be applied directly to the group array to retrieve the minimum and maximum values respectively. The min() method will return the smallest value in the group array, while the max() method will return the largest value. You can use these values for further processing or calculations in your Groovy code.
