The document discusses various optimization techniques that can be applied to basic blocks in code including:
- Common subexpression elimination and dead code elimination to remove redundant computations.
- Algebraic transformations like applying arithmetic identities to simplify expressions and reduce strength of operations.
- Representing the basic block as a directed acyclic graph (DAG) to help identify common subexpressions and apply transformations using properties like commutativity.
Directed Acyclic Graph Representation of basic blocks is the most important topic of compiler design.This will help for student studying in master degree in computer science.

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).

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:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

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.

2. OPTIMIZATION OF BASIC BLOCKS
• The code improving transformations for basic
blocks included structure - preserving
transformations, such as common sub
expression elimination and dead-code
elimination, and algebraic transformation such
as reduction in strength.

3. Cont …
• Many of the structure-preventing
transformation can be implemented by
constructing a dag or a basic blocks
• Recall that there is a node in the dag for each
of the initial values of the variables appearing
in the basic block, and there is a node n
associated with each statement s within the
block.
3/14/2017 3
4. Cont …
• Node n is labeled by the operator applied at s,
and also attached to n is the list of variables for
which it is the last definition within the block.
• If any node’s values are live on exit from the
block, these are the output nodes.
3/14/2017 4
5. Cont …
• Common sub expressions can be detected by
noticing, as a new node m is about to a added,
whether there is an existing node n with the
same children, in the same order, and with the
same operator. If so, n computes the same
value as m and may be used in its place.
3/14/2017 5
6. A dag for the basic block
• a = b + c
• b = a - d
• c = b + c
• d = a – d
• a = b + c
• d = a - d
• c = d + c3/14/2017 6
7. Cont …
• a = b + c
• b = b - d
• c = c + d
• e = b + c

8. The Use of Algebraic Identities
• Algebraic identities another important class of
optimization on basic blocks.
• The simple algebraic transformations that one
might try during optimization.
• For examples apply arithmetic identities, such
as
• x + 0 = 0 + x = x
• x – 0 = x
• x * 1 = 1 * x = x
• x / 1 =x
3/14/2017 8
9. Cont …
• Another class of algebraic optimization
includes reduction in strength, that is,
replacing a more expensive operator by a
cheaper one as in
• x * * 2 = x * x
• 2.0 * x = x + x
• x / 2 = x * 0.5
3/14/2017 9
10. Cont …
• Evaluate constant expressions at compile time
and replace the constant expressions by their
values.
– 2*3.14 => 6.28
• The dag-construction process can help us
apply these and other more general algebraic
transformations such as commutative and
associative
3/14/2017 10
11. Cont …
• For example, suppose * is commutative ; that
is, x * y = y * x.
• Before create a new node labeled * with left
child m and right child n, check whether such
a node already exists, then check for a node
having operator *, let child n and right child m.
3/14/2017 11
12. Cont …
• The relational operators <=, >=, <, >, =, and !=
sometimes generate unexpected common sub
expressions.
• For example
• X – y and x > y
3/14/2017 12
13. Cont …
• Associative laws may also be applied to
expose common sub expressions.
• For example
• a = b + c
• e = c + d +b
Intermediate node generated
• a = b + c
• t = c + d -> a = b + c
• e = t + b -> e = a + d
3/14/2017 13
14. Cont …
• Computer arithmetic does not always the
algebraic identities o mathematics.
• For example, the standard for Fortran77 states
that a integrity of parentheses is not violated.
• Thus, a compiler may evaluate x * y – x * z as
x*(y-z) but it may not evaluate a + ( b – c ) as
( a + b ) - c.
