Segmentation is a memory management scheme that divides logical memory into segments. Each segment has a name, length, and is assigned a segment number. A logical address consists of a two-tuple of <segment-number, offset> that specifies the segment and location within that segment. A segment table maps the logical two-dimensional addresses to one-dimensional physical addresses by storing the base and limit of each segment.

Memory management is the functionality of an operating system which handles or manages primary memory. Memory management keeps track of each and every memory location either it is allocated to some process or it is free. It checks how much memory is to be allocated to processes. It decides which process will get memory at what time. It tracks whenever some memory gets freed or unallocated and correspondingly it updates the status.
Segmentation topic is presented in a most easy way.
Segmentation is a user view of memory in Operating System. Segmentation is one of the most common ways to achieve memory protection. In a computer system using segmentation, an instruction operand that refers to a memory location includes a value that identifies a segment and an offset within that segment.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

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.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:

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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.

ppt on Segmentation in operationg system
1. Segmentation is a memory-management scheme that supports
programer view of memory. A logical address space is a
collection of segments.
OR
Non contiguous approach in every part of a memory is known as
segmentation
2. What is the programmer view of memory? Does the programmer
think of memory as a linear array of bytes, some containing data,
or some other preferred memory view ? There is general
agreement that the programmer of a system does not think of
memory as a linear array of bytes.
3. Each segment has a name and a length. The address specify both the
segment name and the offset(displacement) within the segment.
For simplicity of implementation, segments are referred by a
segment number, rather than by a segment name. Thus, a logical
address consists of a two tuple:
<segment-number , offset>
4. Normally, the user program is compiled, and the compiler
automatically constructs segments reflecting the input
program.
A ‘C’ compiler might create separate segments for the
following:
• Data
• Stack
• Heap
• Code
these all are linked in during compile time might be assigned
separate segments. The loader would take all these segments
and assign them segment numbers.
5. We define an implementation to map two dimentional user-define
address into one-dimentional physical address.
This mapping is affected by a segment table. Each entry in the
segment table has a segment base and a segment limit.
The segment base contain the starting physical address where the
segment resides in memory, whereas the segment limit specifies
the length of the segment.
6.
7. In the next example, consider the situation . We have five segments
numbered from 0 to 4. the segments are stored in physical memory
as shown you in the segment table.
The segment table has a separate entry for each segment, giving the
beginning address of the segment in physical memory (base) and the
length of the segment(limit).
8.
9. It has no internal fragmentation
May save memory if segments are very small and should not be
combined into one page
10. It has external fragmentation
Segments of unequal size not suited as well for
swapping
