Issues of Professional Responsibility

Confidentiality should always be respected regarding employers and clients, with or without formal agreements.
Engineers must accurately represent their competence and avoid taking on work beyond their capabilities.
Awareness of intellectual property laws is critical to protect employers’ and clients' copyrights and patents.
Engineers must refrain from misusing others' computers, which can range from minor infractions to serious offenses.

ACM/IEEE Code of Ethics

Developed by professional societies in the US, detailing ethical practice for software engineers.
Members commit to eight principles guiding their professional behavior, applicable to practitioners, educators, and policy makers.

Rationale for the Code of Ethics

Software plays a pivotal role across various sectors (commerce, government, etc.), instilling a responsibility for software engineers in design, development, and testing.
Engineers have the opportunity to impact society positively or negatively, necessitating a commitment to ethical practices in software engineering.

Wilderness Weather Station

To enhance weather monitoring in remote areas, several hundred weather stations will be implemented.
Stations collect and measure data like temperature, pressure, and wind characteristics through embedded software systems.
Each instrument periodically records data and manages information collection.

Weather Information System

The weather station system processes and transmits collected weather data.
The data management system archives data collected from all stations, facilitating analysis and storage.
The maintenance system monitors the health of the weather stations through satellite communication, reporting any issues.
