Software to Install or Configure (and/or update as needed)

Instructions on installing these follow below.

Recommmended for Everyone

  1. Zoom Client

    Be sure that you have the latest version of the Zoom client. Older versions may not have some of the features we’ll need for this course.

    If you click on “About Zoom” inside zoom, you want a version that is 5.9.1 or later.

    Download it here: https://zoom.us/download

  2. UCSB VPN Client (Pulse Secure)

    What it does:

    • Reroutes all your network traffic through the UCSB network, so that it appears that your machine is directly connected to the UCSB Campus network

    What it allows you to do:

    • Access the textbooks for the course online without having to buy them.
    • Mount your CSIL home directory as a shared network drive using Samba
    • Graphically remote into CSIL

    Note: In order to use Pulse Secure, you need to setup DUO (a two factor authentication app). Here is a link for the instructions on how to set it up: https://www.it.ucsb.edu/getting-started-mfa-duo/enroll-push-notification

    Where to get Pulse Secure: https://www.it.ucsb.edu/pulse-secure-campus-vpn/get-connected-vpn

  3. Samba Access to your CSIL home directory

    What it does:

    • Mounts your CSIL home directory “as if” it were connected directly to your computer.

    What it allows you to do:

    • Click on files on CSIL and open them in software on your own machine (e.g. an editor such as Sublime Text, VSCode, or a web browser.)

    Where to get it:

    • You don’t have to download anything (though you do need the UCSB VPN Client first)

    • Instead, follow the instructions here:

      Platform Text Instructions YouTube Video Instructions
      MacOS Text Video
      Windows Text Video
      Linux (ask staff)  

  4. VSCode Text Editor for your local computer

    While vim and emacs are perfectly fine for the work you may have done in CS16/24/32, when it comes to professional level application development, it’s time to graduate to some more professional tools.

    We have found that VSCode (a free download for Windows/Mac/Linux) is in the sweet spot between too few features, and too complicated.

    If you haven’t worked with it before, we suggest you download it and start getting used to it.

    What it does for you:

    • Autocompletion
    • Syntax highlighting and checking
    • Automatic import detection
    • Ability to see an entire directory tree at once
    • Search and replace across multiple files
    • and much much more…

  5. Install Java 17 on your local system. Please install Java 17, and NOT Java 8, Java 11, or a preview version of Java 18 or 19. It won’t matter for the "Hello World" program in the first week, but when we move on to complex Java applications involving third-party libraries, it will definitely matter.

For Mac users, instructions for installing with Homebrew appear below.

Recommmended for MacOS Users

If you have questions about this section, please ask on the #help-macos channel on the Slack

  1. Command Line Tools XCode for MacOS, including git

    On MacOS, git typically gets installed as part of the “Command Line XCode Tools” the first time you ask to use it. To be sure that git is installed, try typing:

    git --version

    If it shows something like this, you are good:

    git version 2.24.3 (Apple Git-128)

    Otherwise, you might get a message that you need to install the XCode Command Line Tools. In that case, please just follow the instructions given.

  2. Brew (package manager)

    For MacOS, we’ll be installing several packages for Java and JavaScript (node) development.
    In many cases, installing those is easier if you first install the brew package manager.

    To install brew, visit https://brew.sh/ and follow the instructions.

  3. Java 17

    To install Java with homebrew, use:

    brew update
brew install openjdk@17

    After this command finishes executing, there will be a line printed in the terminal that looks like this:

    sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

    You will need to find this line in the text outputted by brew install openjdk@17 and run it in the terminal. It should be near the end of the output.

    The command pasted above will not work; it is an example provided so you know what you’re looking for. This links the software you just installed with the path your computer expects – some macs are different and will have different file structures. That’s why you must use the command outputted by brew install openjdk@17.

    To check if you now have Java 17, open a new Terminal window and do:

    java -version

    If it worked, you should see something like this:

    # java -version
openjdk 17.0.1 2021-10-19
OpenJDK Runtime Environment Homebrew (build 17.0.1+1)
OpenJDK 64-Bit Server VM Homebrew (build 17.0.1+1, mixed mode, sharing)

  4. Maven

    After installing Java 17, you can use brew to install maven:

    brew update
brew install maven

    Or if you already have Maven installed, do this to upgrade your version to the latest one:

    brew update
brew upgrade maven

    Then to check that it is installed, do:

    mvn --version

    Be sure that you have Maven version 3.8 or higher, as Java 17 requires this version to work.

  5. nvm, Node, and npm

    It is recommended to install Node and npm through Node Version Manager (nvm). The instructions for installing this are the same as those for Linux and WSL users, so please follow the instructions listed there.

    Install nvm and Node on WSL

    Update npm on WSL

Recommmended for Windows Users

Install Windows Subsystem for Linux.

It turns out that almost everything in terms of installing software (Java, Maven, Node, etc.) is easier under Linux than under native Windows. Therefore we strongly suggest that if you have a Windows environment, you install the Windows Subsystem for Linux (WSL) and then follow the instructions under Linux/WSL.

If you are unable to install WSL because of limitations on your machine, please reach out to the course staff via Slack using the #help-windows channel on Slack. In that case, we will try to find an alternative for you.

Recommended for Ubuntu Linux / WSL Users

Instructions for installing Windows Subsystem for Linux (WSL), as well as environment setup instructions for Ubuntu systems, is available here: https://ucsb-cs156.github.io/topics/windows_wsl/

Native Ubuntu users (those not using Ubuntu through WSL) can skip the Windows-specific setup and go directly to Install / Update Git on WSL and follow all instructions from there on.

The following programs will be installed in the above guide:

If you’re using a Linux distribution that is not Ubuntu (or a similar Debian-based distribution with access to apt), the commands listed in the setup guide linked above may not work. The staff cannot provide support on finding equivalent commands for your desired distribution, but community resources such as Stack Overflow can help here.
