Todays post will be a few quick examples on the buffer fill method in the nodejs buffer global. The buffer fill method can be used to fill a buffer with a data pattern, so it similar to buffer write but is not a replacement for it, in fact that method is a more robust alternative to buffer fill. The buffer fill method is just a convenience method for something that can be done with buffer write that can be used to write to a buffer in general, rather than just filling a buffer with a pattern.

So then the buffer write method might be more appropriate when it comes to just writing data to a certain location and length to a buffer instance. As such this post will be mostly on the buffer fill method, but also on filling a buffer with data in general, with buffer write, and also the ways that buffers are created to begin with.

So when it comes to doing something in the command line in a posix system, or windows system there is the subject of piping in the command line. That is taking the output of one command line tool and piping it to another tool. For example taking the output of a command that spits out a list of information about the computer the operating system is running on and then piping it to a terminal based txt editor that then saves it as a file in the current working directory.

As of late I wanted to write a nodejs script that can accept input from the standard input, but oddly enough that is something I have not done before, so I had to look into it. In nodejs there is the process global that contains many useful properties, some of which can be used pipe in data from the standard input, as well as out to the standard error and standard output as well. So to get started with this I thought I would write a quick post on the process.stdin property that can be used to stream in the standard input from the command line into a nodejs project.

This is a post on the Node Crypto module pbkdf2 method in nodejs. So pbkdf2 stands for Password Based Key Derivation Function 2, and is a method that can be used to create a key that is to be used with a node crypto module method like createCipheriv.

In todays post I will be writing about the CreateCipher method in the Nodejs Crypto module. This method and the corresponding createDecipher method is a great starting point when it comes to getting started with encryption using nodejs, however when it comes to making an actual real project it might be best to go with the createCipheriv method as that gives more control over the creation of the key, and iv variable. In addition in late versions of nodejs it would appear that this method is now depreciated in favor of createCipheriv. Still in this post I will be going over some quick examples when it comes to simple encryption using nodejs.

The git init command can be used to create a new git folder, so this is one of the first things to look into when it comes to getting started with git. There is also the git clone command that can be used to make a copy of an existing git folder as well, in either case you end up with a git folder.

In this post I will be going over some of the basics when it comes to creating new git folders, there is not much to it when it comes to the basics. However I thought I would make a quick post on this subject just for the heck of it sense I am expanding my content on git as of late. So lets get this one oit of the way so I can get on to more advanced posts on git and source control.
