Keywords

💡Open Source

Open Source refers to a software or project where the source code is made publicly available, allowing anyone to view, use, modify, and distribute the software without restrictions. In the context of the video, the software engineer is working on an Open Source version of Devin, which implies a collaborative and transparent development process. This is exemplified by the creation of a repository where the community can contribute and improve the project.

💡API

API, or Application Programming Interface, is a set of protocols and tools for building software applications. It allows different software systems to communicate with each other, enabling the exchange of data or functionality. In the video, the software engineer is looking for an API to fetch the current exchange rate for converting Yen to Euros. This highlights the importance of APIs in accessing and utilizing data from external sources within a program.

💡Terminal

The terminal is a command-line interface that allows users to interact with the operating system by typing commands. It is a powerful tool for developers as it provides direct control over the system and its processes. In the video, the software engineer uses the terminal to execute various tasks, such as listing files in the workspace, installing Node.js, and running the program, demonstrating the terminal's versatility and efficiency in software development.
