- For advanced developers: master the skills to efficiently apply PowSyBl functionalities to your real-world scenarios.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

The main method
22
23. Comments
In Java, comments are
preceded by two slashes (//)
in a line, or enclosed
between /* and */ in one or
multiple lines. When the
compiler sees //, it ignores
all text after // in the
same line. When it sees /*,
23
24. Package
The second line in the program
(package chapter1;) specifies a package
name, chapter1, for the class Welcome.
Forte compiles the source code in
Welcome.java, generates
Welcome.class, and stores
Welcome.class in the chapter1 folder.
24
25. Reserved Words
Reserved words or keywords are
words that have a specific
meaning to the compiler and
cannot be used for other
purposes in the program. For
example, when the compiler sees
the word class, it understands
that the word after class is the
name for the class. Other
reserved words in Example 1.1
25
26. Modifiers
Java uses certain reserved words called
modifiers that specify the properties of the
data, methods, and classes and how they
can be used. Examples of modifiers are
public and static. Other modifiers are
private, final, abstract, and protected. A
public datum, method, or class can be
accessed by other programs. A private
datum or method cannot be accessed by
other programs. Modifiers are discussed in
26
Chapter 6, "Objects and Classes."
27. Statements
A statement represents an
action or a sequence of
actions. The statement
System.out.println("Welcome
to Java!") in the program in
Example 1.1 is a statement
to display the greeting
"Welcome to Java!" Every
27
statement in Java ends with
28. Blocks
A pair of braces in a program
forms a block that groups
components of a program.
public class Test {
public static void main(String[] args) {
System.out.println("Welcome to Java!");
}
}
Class block
Method block
28
29. Classes
The class is the essential Java
construct. A class is a template
or blueprint for objects. To
program in Java, you must
understand classes and be able
to write and use them. The
mystery of the class will
continue to be unveiled
throughout this book. For now,
though, understand that 29
a
30. Methods
What is System.out.println? It is a method: a
collection of statements that performs a
sequence of operations to display a
message on the console. It can be used
even without fully understanding the
details of how it works. It is used by
invoking a statement with a string
argument. The string argument is enclosed
within parentheses. In this case, the
argument is "Welcome to Java!" You can
call the same println method with a
30
31. main Method
The main method provides the
control of program flow. The
Java interpreter executes the
application by invoking the main
method.
The main method looks like this:
public static void main(String[]
args) {
31
32. Displaying Text in a Message
Dialog Box
you can use the showMessageDialog
method in the JOptionPane class.
JOptionPane is one of the many
predefined classes in the Java system,
which can be reused rather than
“reinventing the wheel.”
Source
Run
32
34. The exit Method
Use Exit to terminate the program and stop
all threads.
NOTE: When your program starts, a thread
is spawned to run the program. When the
showMessageDialog is invoked, a separate
thread is spawned to run this method. The
thread is not terminated even you close the
dialog box. To terminate the thread, you
have to invoke the exit method.
