IoT Challenges: Technological, Business and Social aspectsRoberto Minerva
Internet of Things is promising to be a set of technologies able to have a high impact on how people live, produce, modify and interact with the environment. Such a transformation is driven by increasing technologies capabilities of sensors/actuators, communications, general-purpose hardware, availability of software and programmability of devices. The integration of so different technologies is a problem in itself and IoT is also trying to solve cogent issues of specific problem domains, such as e-health, transportation, manufacturing, and so on. Large IoT systems (e.g., smart cities) stand on their own because the smartness requires integration of different technologies, processes and different administrative domains creating the needs to deal with a complex system. In addition to technological and problem domain specific challenges, there exist further challenges that fall in business, social and regulation realms. They can greatly impact the deployment and the success of IoT deployment. The speech aims at providing a view on some major technologies challenges of IoT and to cover a few critical business and social issues that could hamper the large deployment of IoT systems by providing some examples of implementation.

The document discusses efficient processing of complex data through BFS graph traversal. It describes constructing a graph from a data file by adding nodes and edges. It then performs BFS traversal on the graph, maintaining a queue of nodes to visit and propagating information to discover paths between nodes.
The document discusses artificial intelligence and human thinking. It proposes the Abductive Logic Programming (ALP) agent model as a unifying framework for both. ALP clausal logic can serve as the Language of Thought (LOT), representing a private, language-like representation in the mind. Additionally, ALP clausal logic can function as a connectionist model of the mind by representing concepts and relationships between concepts.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Ex : no manual start, optimal power management
Dependability: guaranteed minimal service in any case
Ex : attacks, hardware failures, software execution errors
Scalability: at runtime or evolutionary growth (linear performance
increase with resources)
Ex : reconfiguration, scalable services

17. System Design – Still a long way to go
Design of large IT systems is a risky undertaking, mobilizing hundreds of engineers
over several years.
Difficulties
Complexity – mainly for building systems by reusing existing
components
Requirements are often incomplete, and ambiguous
(specified in natural language)
Design approaches are empirical and based
on the expertise and experience of teams
Consequences
Large IT projects are often over budget,
over time, and deliver poor quality.

20. Basic technologies – multicore systems
A multicore system integrates many cores
(processors) on a chip
The switch to multicore systems
is not at all the consequence of a scientific breakthrough,
is primarily due to technology walls that prevent from pushing forward
the efficient implementation of traditional uniprocessor designs in silicon
Increasing application's efficiency, simply by upgrading the hardware
without significantly changing the software, is not anymore possible for
multicore systems.
The promise of parallel machines delivering almost unlimited computing
power is not new. For decades there have been numerous industrial
attempts in this direction, but almost all failed.
21. Basic technologies – multicore systems
“Software is struggling to keep pace with the fast growth of multicore
processors”
“Running advanced multicore machines with today's software is like "putting
a Ferrari engine in a go-cart,“
"Many of the software configurations in use today will be challenged to
support the hardware configurations possible, and those will be accelerating
in the future."

Security: protection of information from unauthorized access, use, disclosure,
disruption, modification or destruction.
Key requirements:
Confidentiality is the property of preventing disclosure of information to
unauthorized individuals or systems
e.g. for credit card transactions
Integrity means that data cannot be modified without authorization
e.g. resistance to viruses
Availability, that is information must be available when it is needed
e.g. preventing denial-of-service attacks.
Authenticity, that is ensuring that the transactions, communications and data
are genuine.
Non-repudiation that is ensuring that a party in a dispute cannot repudiate, or
refute the validity of a statement or contract
e.g. electronic check or contract.
25. Internet-based Systems – The Internet of Things
The “Internet of Things” will be the result of the convergence between
Embedded Systems and the Internet.
Basic idea: Use the Internet Protocol Suite for Human/ES or ES/ES interaction
This is not as easy as it seems.
Some major breakthroughs needed:
Wireless sensor networks and RFID technologies.
Advances in miniaturization and nanotechnology mean that smaller and
smaller things will have the ability to interact and connect.
Getting IP down to small devices and implementing features for QoS
control and responsiveness.
Standards e.g. for naming objects, tools and platforms.
Improving overall security, and reliability of the internet.

51. Adaptivity – Critical vs. Best Effort Engineering
Two diverging design paradigms
BAD STATES ERROR STATES
Critical systems engineering based Best effort engineering
on worst-case analysis and static based on average case analysis
resource reservation e.g. hard real- and dynamic resource
time approaches, massive management e.g. Quality of
redundancy. Service for optimizing speed,
memory, bandwidth, power.
Leads to over-dimensioned systems No guaranteed availability
52. Adaptivity – Enhancing Predictability
Separation between critical and best-effort designs is not anymore
affordable. In a car
more than 50 ECU’s each designed separately
federated architectures by using networks
poor global reliability and high development costs
1. Predictability through determinism - reduce intrinsic and estimated
uncertainty
Simplify HW architectures e.g. no caches, no out-of-order execution
Time-deterministic observable behavior e.g. time triggered systems
2. Adaptive architectures integrating both critical and best-effort services
sharing an amount of global resources used
first and foremost for ensuring critical services
secondarily, for meeting quality of service requirements for non
critical services

55. A Vision for Computer Science
Computer Science
Is a young and rapidly evolving discipline due to exponential
progress of technology and applications
Focuses on building systems and thus system design is central to the
discipline
Existing models of computation should be extended to encompass
physicality – physical resources e.g. memory, time, energy should
become first class concepts
Complements and enriches our knowledge with theory and models
that allow a deeper understanding of discrete dynamic systems
Proposes a constructive and operational view of the world which
complements the classic declarative approach adopted by Physics

61. A Vision for Computer Science – Research in CS
The Business as Usual Syndrome
Following beaten tracks rather taking the risk of exploring
new ideas
The Hype Syndrome
All of the following were once hyped as main
breakthroughs in CS:
Artificial Intelligence, Fifth Generation Computers,
Program Synthesis, True Concurrency, Program proofs
The Nice Theory Syndrome
The proper goal of theory in any field is to make
models that accurately describe real systems. These
models should help system builders do their jobs
better.
Unfortunately, the current scope and focus of research
in CS fail to address basic problems raised by system
design and engineering
62. A Vision for Computer Science – Research in CS
Nice theory is not always practically relevant
“Make everything as simple as possible, but not simpler”
“….. in the academic world the theories that are more likely to
attract a devoted following are those that best allow a clever but
not very original young man to demonstrate his cleverness.”
…..but we need nice theory for solving practically relevant
problems
“Perfection is reached not when there is no longer anything to
add, but when there is no longer anything to take away”
63. A Vision for Computer Science – Research in CS
Is it possible to find a mathematically elegant and still practicable
theoretical framework for CS?
Physics and Biology study a given “reality”
The key issue is discovering
laws governing phenomena
"The most incomprehensible thing
about the world is that it is at all
comprehensible."
Computer Science deals with building artifacts
The key issue is Constructivity
that is the capability to build
cost-effectively correct systems
64. A Vision for Computer Science – Teaching CS
Prepare students to deal with constant change induced by
technology and applications
Learn principles rather than facts (foundations, architectures,
protocols, compilers, simulation …)
Think in terms of systems (design process, tools, interaction with
users and physical environment)
Keep aware of limitations of existing theory of computing
Introduce principles, paradigms, techniques from Control Theory
and Electrical Engineering
Put emphasis on information and computation as universal
concepts applicable not only to computers
Provide the background for triggering critical thinking,
understanding and mastering the digital world.
