The world faces escalating crises: record-breaking temperatures, widespread fires, severe flooding, increased oceanic microplastics, and unequal resource distribution. Academia introduces courses around sustainability to meet the new demand, but software engineering education lags behind. While software systems contribute to environmental issues through high energy consumption, they also hold the potential for solutions, such as more efficient and equitable resource management. Yet, sustainability remains a low priority for many businesses, including those in the digital sector. Business as usual is no longer viable. A transformational change in software engineering education is urgently needed. We must move beyond traditional curriculum models and fully integrate sustainability into every aspect of software development. By embedding sustainability as a core competency, we can equip future engineers not only to minimise harm but also to innovate solutions that drive positive, sustainable change. Only with such a shift can software engineering education meet the demands of a world in crisis and prepare students to lead the next generation of sustainable technology. This article discusses a set of challenges and proposes a customisable education roadmap for integrating sustainability into the software engineering curricula. These challenges reflect our perspective on key considerations, stemming from regular, intensive discussions in regular workshops among the authors and the community, as well as our extensive research and teaching experience in the field.

Achieving the UN Sustainable Development Goals (SDGs) demands a shift by industry, governments, society, and individuals to reach adequate levels of awareness and actions to address sustainability challenges. Software systems will play an important role in moving towards these targets. Sustainability skills are necessary to support the development of software systems and to provide sustainable IT-supported services for citizens. While there is a growing number of academic bodies including sustainability education in engineering and computer science curricula, there is not yet comprehensive research on the competencies and skills required by IT professionals to develop such systems. This study aims to identify the industrial sustainability needs for education and training from software engineers’ perspective. For this, we answer the following questions: (1) what are the interests of organisations with an IT division with respect to sustainability? (2) what do organisations want to achieve with respect to sustainability, and how? and (3) what are the sustainability-related competencies and skills that organisations need to achieve their sustainability goals? We conducted a qualitative study with interviews and focus groups with experts from twenty-eight organisations with an IT division from nine countries to understand their interests, goals, and achievements related to sustainability, and the skills and competencies needed to achieve their goals. Our findings show that organisations are interested in sustainability, both idealistically and increasingly for core business reasons. They seek to improve the sustainability of software processes and products but encounter difficulties, like the trade-off between short-term financial profitability and long-term sustainability goals or an unclear understanding of sustainability concepts from a software engineering perspective. To fill these gaps, they have promoted in-house training courses, collaborated with universities, and sent employees to external training. The acquired competencies should support translating environmental and social benefits into economic ones and make sustainability an integral part of software development.

As TV consumers expect a growing quantity and quality of services provided to them, and providers fear uncontrolled distribution of the digital content, one of the more promising theoretical proposals to balance these two needs are the so-called "Authorized Domains" (AD). We present in this paper a novel architecture that builds on the AD concept, but extends it to allow for a more generic, open, and flexible solution. The contributions of our work are twofold: First, we analyze and motivate which features a generic and flexible IPTV architecture should exhibit in order to enable various business models, while maintaining in all instances the above-mentioned core features. Second, we present our architecture – “Personal Home Domains” (PHD) –, which adds some key features to the original AD: it allows offline content in addition to streaming; it harmonizes the distribution inside the domain with (new) the delivery from service provider to the domain; it allows for the distribution of free or age-protected content; it emphasizes the mobility of users more than the original concept; and it allows for non-compliant devices inside the domain devices as well.

From the four basic functionalities of video delivery systems - linear TV, video on demand (VoD), time-shifted TV (tsTV), and network personal video recorder (nPVR) - most of today's solutions focus either on linear TV, or on VoD. While linear TV usually uses efficient distribution mechanisms such as multicast, VoD is often realized via centralized, bandwidth- inefficient unicast. Even when file sharing P2P algorithms are used for VoD or nPVR, they can not be applied to tsTV since they require the whole content to exist from the beginning. With this paper, we propose a novel solution that aims at offering all four functionalities in one distributed system. Our architecture uses multicast for the distribution of live content, and a modified P2P protocol for offering VoD, nPVR, and tsTV altogether.
