Types of computer buses include parallel and serial buses. Parallel buses have multiple data, address, and control lines that send information simultaneously. Serial buses send this information sequentially down a single wire. Buses require arbitration mechanisms to determine which device can access the bus at a given time, such as centralized or distributed arbitration. Fair and urgent arbitration help allocate bus access between devices.

It is a term used to categorise methods of
construction which use locally available
resources and traditions to address local
needs.
Vernacular architecture tends to evolve over
time to reflect the environmental, cultural
and historical context in which it exists.
It has often been dismissed as crude and
unrefined, but also has proponents who
highlight its importance in current design.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
2. Buses – Common Characteristics
• Multiple devices communicating over a single set of
wires
• Only one device can talk at a time or the message is
garbled
• Each line or wire of a bus can at any one time contain
a single binary digit. Over time, however, a sequence
of binary digits may be transferred
• These lines may and often do send information in
parallel
• A computer system may contain a number of different
buses
3. Buses – Structure
• Bus lines (parallel)
– Data
– Address
– Control
– Power
• Bus lines (serial)
– Data, address, and control are sequentially sent down
single wire
– There may be additional control lines
– Power
4. Buses – Structure (continued)
• Data Lines
– Passes data back and forth
– Number of lines represents width
• Address lines
– Designates location of source or destination
– Width of address bus specifies maximum
memory capacity
– High order selects module and low order selects
a location within the module
5. Bus Structure – Control lines
• Because multiple devices communicate on a line,
control is needed
• Timing
• Typical lines include:
– Memory Read or Write
– I/O Read or Write
– Transfer ACK
– Bus request
– Bus grant
– Interrupt request
– Interrupt acknowledgement
– Clock
– Reset
6. Operation – Sending Data
• Obtain the use of the bus
• Transfer the data via the bus
• Possible acknowledgement
7. Operation – Requesting Data
• Obtain the use of the bus
• Transfer the data request via the bus
• Wait for other module to send data
• Possible acknowledgement
10. Single Bus Problems
Lots of devices on one bus leads to:
• Physically long buses
– Propagation delays – Long data paths mean that co-
ordination of bus use can adversely affect performance
– Reflections/termination problems
• Aggregate data transfer approaches bus
capacity
• Slower devices dictate the maximum bus
speed
11. Multiple Buses
• Most systems use multiple buses to
overcome these problems
• Requires bridge to buffer (FIFO) data due to
differences in bus speeds
• Sometimes I/O devices also contain
buffering (FIFO)
12. Multiple Buses – Benefits
• Isolate processor-to-memory traffic from
I/O traffic
• Support wider variety of interfaces
• Processor has bus that connects as direct
interface to chip, then an expansion bus
interface interfaces it to external devices
(ISA)
• Cache (if it exists) may act as the interface to
system bus
13. Bus Arbitration
• Listening to the bus is not usually a
problem
• Talking on the bus is a problem – need
arbitration to allow more than one
module to control the bus at one time
• Arbitration may be centralised or
distributed
14. Centralised vs. Distributed Arbitration
• Centralised Arbitration
– Single hardware device controlling bus access –
Bus Controller/Arbiter
– May be part of CPU or separate
• Distributed Arbitration
– Each module may claim the bus
– Access control logic is on all modules
– Modules work together to control bus
15. Bus Timing
• Co-ordination of events on bus
• Synchronous – controlled by a clock
• Asynchronous – timing is handled by well-
defined specifications, i.e., a response is
delivered within a specified time after a
request
16. Bus Width
• Wider the bus the better the data transfer
rate or the wider the addressable memory
space
• Serial “width” is determined by
length/duration of frame
17. Higher Performance External Buses
• Historically, parallel has been used for high speed
peripherals (e.g., SCSI, parallel port zip drives
rather than serial port). High speed serial,
however, has begun to replace this need
• Serial communication also used to be restricted to
point-to-point communications. Now there's an
increasing prevalence of multipoint
18. Arbitration – Basic form
• Upon automatic configuration, each tree designates
a root
• Parent/child relationship forms tree topology
• Root acts as central arbitrator
• Requests are first-come-first-serve
• Simultaneous requests are granted first to the
closest node to the root and second to the lower ID
number
• Two additional functions are used to best allocate
the use of the bus
– Fair arbitration
– Urgent arbitration
19. Fair arbitration
• Keeps one device from monopolizing the bus by
allowing only one request during a set fairness
interval
• At beginning of interval, all devices set arbitration
enable flag
• Each device may compete for bus access
• If bus access is granted, arbitration enable flag is
cleared prohibiting bus access until next fairness
interval
20. Urgent arbitration
• Allows overriding of fairness interval by
nodes configured as having an urgent
priority
• Provides support for devices with severe
latency requirements or high throughput
such as video
• They may use the bus up to 75% of the time,
i.e., for each non-urgent packet, three urgent
packets may be sent
