# Requirements
We do not write code for the sake of writing code: we develop software to _help people perform tasks_.
These people can be "anyone on Earth" for widely-used software such as GitHub, "people who do a specific job" for internal applications,
or even a single person whose life can be helped with software.

# Performance
Producing correct results is not the only goal of software.
Results must be produced in reasonable time, otherwise users may not wait for a response and give up.
Providing a timely response is made harder by the interactions between software components and between software and hardware, as well as the in... | CS-305: Software engineering |
# Debugging
> **Prerequisite**: You are _strongly_ encouraged, though not strictly required, to use an IDE for the exercises about debugging in this lecture.
> Alternatively, you can use Java's built-in command-line debugger, `jdb`, but it is far less convenient than a graphical user interface.

# Asynchrony
You're writing an app and want it to download data and process it, so you write some code:
```java
data = download();
process(data);
```
This works fine if both of these operations finish in the blink of an eye... but if they take more than that, since these operations are all your code is doing,
your use... | CS-305: Software engineering |
# Infrastructure
> **Prerequisites**: Before following this lecture, you should:
> - Install Git. On Windows, use [WSL](https://docs.microsoft.com/en-us/windows/wsl/install) as Git is designed mostly for Linux.
> On macOS, see [the git documentation](https://git-scm.com/download/mac). On Linux, Git may already be in... | CS-305: Software engineering |
