 ## The Linux Command Line
 
-The primary software environment used in CDC will be an Ubuntu Linux virtual machine (VM). An efficient way for interacting with Linux is the use of the command line (also called the terminal/shell/prompt), a textual interface to issue commands for execution by the Linux OS. In the CDC Ubuntu VM, you can open the terminal by clicking on the following icon: ![Terminal Icon](images/terminal.png)

-As an *interpreted* language, Python code is not precompiled to executable machine code but rather read and executed by an interpreter. This makes Python very flexible and easy to use, but means it is not fast enough to implement computationally intensive signal processing blocks. See the next section on C++.

 ## Version Control with Git
 
-A version control tool tracks changes to the software codebase of a project, allowing multiple team members to develop concurrently. Such tools allow for rolling back to previous versions of the code when mistakes are introduced and also allow the merging of conflicting changes made to the codebase. These days, Git is the most widely used version control tool for managing source code.

Such tools allow for rolling back to previous versions of code when mistakes are introduced and for the merging of conflicting changes made to the codebase by different developers.

 We will maintain a number of GNU Radio modules, useful code and templates, and this wiki (!) in a CDC project hosted on the university's Gitlab server.
