| [[https://code.visualstudio.com/|Microsoft Visual Studio Code]] (VS Code) is a popular source code editor and IDE that is available for free and which can run on Linux, Windows and macOS systems. It allows connecting to remote environments and working from them and the installation of extensions to support different programming languages and make use of additional development tools. Because of this, it is suitable for connecting to Hábrók to perform software development tasks. There are two main ways to use VS Code from Hábrók, either by connecting your local VS Code installation client via SSH to a VS Code server running in one of the access nodes, or by running it directly on your browser through our [[https://portal.hb.hpc.rug.nl/|web portal]]. | [[https://code.visualstudio.com/|Microsoft Visual Studio Code]] (VS Code) is a popular source code editor and IDE that is available for free and which can run on Linux, Windows and macOS systems.
