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).

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:
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!
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.

Communications Mining Series - Zero to Hero - Session 1DianaGray10
This session provides introduction to UiPath Communication Mining, importance and platform overview. You will acquire a good understand of the phases in Communication Mining as we go over the platform with you. Topics covered:
• Communication Mining Overview
• Why is it important?
• How can it help today’s business and the benefits
• Phases in Communication Mining
• Demo on Platform overview
• Q/A
2. History
• Creator, Maintainer, Chief Architect – Larry
Wall
• Practical Extraction and Report Language
• Pathologically Eclectic Rubbish Lister
• Pearl
• Features from C, awk, tcl/tk
3. Basic
• Use any editor to write a Perl program
• Extension is .pl
• Run in Unix as $perl <filename>
• Make it executable and run as
$./<filename>
4. Hello World!
• Always the first line
#!/usr/local/bin/perl is #!<pathtoperl>
print “Hello Worldn”; • print prints to the
standard output
• print can also be
used for printing
into files
5. Standard Input/Output
• Get the input from the user using <STDIN>
– $x = <STDIN> gets the input from the user
• Print to the standard output
– print $x prints the value of $x
– print “hello “,”world”,”n” prints hello world and newline
character
– print “hello ”.”world”.”n” also prints hello world and
newline character
– So what's the difference?!?!
7. Scalar Variables
• Basic kind
• Can hold both numerics and strings and
interchangeable
– Eg.: $temp = ‘hi’
– $temp = 9
• Starts with “$” symbol followed by a letter
and then by letters, numbers or
underscores
• Case sensitive
8. Numbers
• Integers and Floats
• Internally, Perl computes with double float
• Integer Literals
– 25
– 013 and 13 are different!!!!
• Float Literals
– 1.3
– -13e-19 == -1.3E-19
10. String Literals
• Single quoted
– Anything inside the quotation has no special
meaning except ' and
– 'hey'
– 'heytwazzup' is heytwazzup
• Double quoted
– Some characters have special meanings
– “heytwazzup” is hey wazzup
12. Number <--> String Operators
• Careful with the Operators!
• (1+1) x 3 = 222
• “a” + “b” is not an error
• Be CAREFUL!
13. Assignment Operators
• Assignment $LHS = $RHS
– The value on the right is assigned to the left
– $x = ($y = 13)
– $x = $y = 13
• $x and $y has the value 13
• Binary Assignment
– If the variable in LHS and RHS are same
– $x = $x + 13 $x += 5
– Similarly, for other binary operators
14. Auto [Increment, Decrement]
• Similar to C
• For both integers and float
• ++ operator adds 1 to its operand
• -- operator subtracts 1 from its operand
• $x = $y++ is different from $x = ++$y
15. Chop and Chomp
• Chop
– Removes and returns the last character from the
input
– $x = “huhn”
– chop ($x) makes $x = “huh”
– chop ($x) makes $x = “hu”
• Chomp
– Removes only the “n” from the input
– $x = “huhn”;
– chomp ($x) makes $x = “huh”
– chomp ($x) makes $x = “huh”
16. Array
• List is ordered scalar data
• Array holds list
• No limits
• Array variable name starts with @
– @var1
• Individual elements can be accessed
using $
– $var1[0] is the first element
17. Array Examples
• List literals
– (1,2,3)
– (“hello”,1,1.2)
– ($x+$y,10)
– List constructor
• (1..5) is (1,2,3,4,5)
• Array
– @a = (“hey”,”how”,”are”,”you”)
18. Array Functions
• Sort
– @x = sort (@y) will sort the array y and store it
in x
• @x = sort (“b”,”a”,”c”) will make @x = (“a”,”b”,”c”)
• @x = sort (3,12,4,15) will make @x = (12,14,3,4)!!
• Sort by number
– @x = sort {$a <=> $b} (3,12,4,15) will make @x
= (3,4,12,15)
19. Array Functions (cont.)
• Reverse reverses the order of the
elements in the array
– @x = reverse (3,2,8) will make @x = (8,2,3)
• Chomp removes the “n” from all the
elements of the array
– @x = chomp (“hellon”,”heyn”) will make @x =
(“hello”,”hey”)
20. Regular Expressions
• Useful and Powerful string manipulation
functions
• RE is a pattern to be matched against a
string
• The regular expression is contained within
slashes and the matching operator is =~
21. Is it easy?!?
• To find a pattern “hahaha” in a string $x
– $x =~ /hahaha/
– If the above statement is true then “hahaha” is
present in $x
22. Regular Expression Characters
• Some special regular expression
characters
– . Single Character except newline
– ^ Beginning of line
– $ End of line
– * Zero or more of the last character
– + One of more of the last character
– ? Zero or one of the last character
24. Some more symbols
• Square brackets
– To match any one character inside the bracket
– Inside the bracket “^” indicates not
– And “-” indicates between
• Parenthesis
– To group characters together
• “|”
– Either or
26. Substitution
• $varname =~ s/old/new
– The regular expression old will be replaced by
new
• $varname =~ s/old/new/g
– All the old regular expressions will be replaced
by new
27. Split
• Splits a string based on the regular
expression given
– @parts = split (/<regExp>/, $x)
– Eg.: $x = 1:2:3:4
– @parts = split (/:/, $x)
– @parts = (1,2,3,4)
