Tools

The default Java version on our systems is currently 21. If you’re using a tool that lets you choose, we recommend using Java 21. The most common IDE among professionals who use Java is IntelliJ Idea. (On our systems, it is called “idea”.) It has greatly surpassed Eclipse, Netbeans, and VSCode. We recommend learning it if you want an IDE.

• • Introduction to Intellij Idea Java IDE.
  • Java Development with NetBeans IDE Quick 10 minutes tutorial of using NetBeans to do Java Development,
  • Intro to Eclipse for Java Eclipse is one of the two major development environments for Java. (The other is Netbeans.) Since we have already installed it, you can skip downloading and installing it using a computer science system.
  • Using VisualCode for Remote Development [video] A quick tutorial on remote development using VSCode. Remote development allows you to use VSCode IDE on your local computer while your work and execution are on the remote computer.
  • A Crash Course Tutorial on VSCode For users who prefer to use VSCode, watching a crash course on developing using VSCode may be the best way to spend time.
  • Maven in 5 Minutes. You will want to use Maven or Gradle to build programs outside Eclipse. These download libraries allow you to create jar files, war files, etc.

  • Learning Python Codecademy is an excellent resource for you to learn Python language very quickly.
  • Intro to Python for Data Science DataCamp has a free course on using Python for Data Science
  • Best Python Resources for Beginners and Professionals It’s a very nice collection of Python language resources for everyone.
  • Python & Deep Learning on the Cloud using Google Colab with GPU support “Colaboratory is a Google research project created to help disseminate machine learning education and research. It’s a Jupyter Notebook environment that requires no setup and runs entirely in the cloud.”
  • Spyder Introduction. For development, we suggest using a Development Environment such as Spyder. It is already installed in our Anaconda environments, so you can ignore the “conda install” commands in the introduction. Spyder has a reputation for being good for data science. Many of our users like PyCharm. Unfortunately, its licensing doesn’t let us install it, but you can install the free version yourself. Warning: it tends to run away, writing files until your disk quota is full.

Tool’s Notes:

• • Remember, whatever the tutorials say, don’t type “python”. Type python3 instead.
  • With pip, unless you use your environment, be sure to use pip install --user so the packages go into your directory. Do not update pip, even though it may tell you to.
  • VScode and pycharm are roughly tied for IDEs in terms of number of users.
  • If you need to install your packages with a Python environment, create a whole environment with copies of all the files.
  • You can use pip install --user. This command puts the packages it installs in ~/.local/lib/pythonXX/site-packages/.
