AssignmentModify the Python program by adding the create_dictiona.pdftsekar2004
Assignment:
Modify the Python program by adding the create_dictionary function. The parameter file_name
is the name of the csv file that contains several lines of ASCII encodings. The format of this file
is described in the link above. The function should return a dictionary where the keys are
characters and the values are the 8 bit representations. Note: use the characters for comma, quote,
and space characters, instead of the words comma, quote, and space.
Add the translate function. The parameter sentence consists of a number of characters. The
parameter dictionary is the dictionary returned by the create_dictionary function. The parameter
file_name is the name of the output file where all output should be sent. In the output file, the
text should be a binary string (zeros and ones only) with each 8 bit ascii code appearing one after
the other. (see sample transcripts)
If a character does not appear in the dictionary, the string "\nUNDEFINED\n" should appear
instead of an 8 bit representation.
When the program is run, it should produce the following three output files: output-1.txt, output-
2.txt and output-3.txt.
Grading:
2 points - The create_dictionary function returns a dictionary that contains the correct binary
code for each character of length one.
1 point - The create_dictionary function returns a dictionary that contains the correct binary code
for comma, quote, and space.
3 points - When your program is tested with different values for the variable sentence, all
characters that exist in the dictionary are translated correctly.
1 point - When your program is tested with different values for the variable sentence, characters
that do NOT exist in the dictionary are translated correctly to the word UNDEFINED on a line of
its own.
1 point - The format of any output files created match the format of the sample output files
exactly. def create_dictionary(f): \# f is the filename; rename the parameter as you wish pass \#
open the file for reading and assign to a file handle variable* \# make a dictionary variable -- it
can be empty to start with \# use the file handle variable step through each line doing this.." \#

Through this programming assignment, the students will learn to do the following: 1. Practice
processing command line arguments. 2. Perform basic file I/O. 3. Use structs, pointers, and
strings. 4. Use dynamic memory. This assignment asks you to create a doubly linked list which will
be used to sort the words in an input file and print the sorted words to an output file (or standard
output) which will be the solution. Your program, called doublesort, will take the following
command line arguments: % doublesort [d] [-o output_file_name] input_file_name Read the words
in from the input file one at a time. Convert all the letters to lower case. Skip any punctuation or
special characters. If the output_file_name is given with the -o option, the program will output the
sorted letters to the given output file; otherwise, the output shall be to standard output. In addition
to parsing and processing the command line arguments, your program needs to do the following:
1. You need to construct a doubly linked list as you read from input. Each node in the list will link
to the one in front of it and the one behind it if they exist. They will have NULL for the previous
pointer if they are first in the list. They will have NULL for the next pointer if they are last in the list.
You can look up doubly linked lists in your Data Structure textbook. 2. Initially the list is empty. The
program reads from the input file one word at a time and converts it to lower case. Create a node
with a pointer to the word and 2 pointers to nodes, previous and next. Initially the previous and
next pointers should be NULL. 3. As long as you continue reading words, if the word is not already
in the list, create a new node and place the node into the list in the proper alphabetical order. If
there is a node in front of it, adjust the next pointer of that node to point to the new node and make
the previous pointer of the new node to point to the node in front of it. If there is a node after it then
adjust those pointers as well so the list remains continuous. All duplicate words are ignored. 4. An
end of file would indicate the end of input from the input file. 5. Once the program has read all the
input, the program then performs a traversal of the doubly linked list first to last, or last to first if the
- d option is set, to print one word at a time to the output file or stdout. Print one word per3. As
long as you continue reading words, if the word is not already in the list, create a new node and
place the node into the list in the proper alphabetical order. If there is a node in front of it, adjust
the next pointer of that node to point to the new node and make the previous pointer of the new
node to point to the node in front of it. If there is a node after it then adjust those pointers as well
so the list remains continuous. All duplicate words are igno.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

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.
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!

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:

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).

2. A lisp symbol is a data object that has three user-visible components: The property list is the list that effectively provides each symbol with many modifiable named components. The print name must be the string, which is the sequence of characters used to identify the symbol. The package cell must refer to package object. A package is a data structure used to locate a symbol once given the symbols name. A symbol is uniquely identified by its name only when considered relative to a package.
3. overview The property List The Print name Creating symbols Packages Translating strings to Symbols Export and import symbols Name conflicts Built-in packages
4. The property list A property list contains two or more entries, with each entry associated with the key called the indicator. A property list is very much similar to an association list in its purpose, but the difference is that a property list is an object with unique identity. A property list is implemented as a memory cell containing a list with even number(possibly zero) of elements. Each pair of elements in the list constitutes an entry: the first item is the indicator, the second item is the value. When the symbol is created its property list is initially empty, properties are created by using get within a set form.
5. get symbol indicator1 &optional default Get searches the property list of the symbol for an indicator eq to indicator1. if one is found, the corresponding value is returned, else default is returned. Suppose the property list of foo is ( bar t baz 3 hunoz “huh?”) Then ex: (get ‘foo ‘baz)3 (get ‘foo ‘hunoz)”Huh?” (get ‘foo ‘Zoo) nil
6. remprop symbol indicator1 This removes the symbol from the property with an indicator eq to indicator1. Suppose if property foo was (color blue height 6.3) After using (remprop ‘foo ‘height) the property becomes (color blue) Returns the list that contains the property pairs of the symbol, the contents of the property lists are extracted and returned. symbol-plist symbol
7. getf place indicator1 &optional default getf searches for the property list stored in place for an indicator eq to indicator1, if found returns the corresponding value, else returns the default or nil. remf removes from the property list stored in the place the property with an indicator eq to indicator1 . The property indicator and the corresponding value are removed by destructively splicing the property list. remf place indicator1

10. Creating Symbols Symbols are used in two different ways: An interned symbol is one that is indexed by its print name in its catalog called a package. An uninterned symbol is one that is used simply as a data object with no special cataloguing. An uninterned symbol is printed with #: followed by its print name. make-symbol print-name creates a new uninterned symbol whose print name is the string print-name.
11. copy-symbol sym &optional copy-props returns a new uninterented symbol with the same name as of the sym. If copy-props is non-nil, then the initial value and function definition of the new symbol will be the same as those of the sym, and the property list of the new symbol will be a copy of sym’s. gensym &optional x gensym invents a print name and creates a new symbol with that print name. it returns new uninterented symbol. The invented new print name consists of a prefix( which defaults to G) , followed by decimal representation of a number. The number is increased by 1 every time gensym is called.
12. gentamp &optional prefix package gentemp like gensym, creates and returns new symbol. The only difference is gentemp interns the symbol in the package. Symbol-package sym returns the contents of the package cell of that symbol. This will be a package object or nil. Keywordp object returns true if the argument is a symbol and that symbol is a keyword.
13.
14. internal( normally hidden from other packages).A symbol is said to be interned in a package if it is accessible in that package and also is owned.
15.
16. Print-read consistency: An interned symbol always as a sequence of characters that, when read back in, yields the same (eq) symbol.
17.
18. Translating strings to symbols Whatever packet object is currently the value of *package* is referred to as current-package. When the lisp reader has obtained a string of characters thought to name a symbol, that name is looked up in the current package. If the name is found, the corresponding symbol is returned, if the name is not found, a new symbol is created for it and is placed in the current package as an internal symbol. External symbol in some other package is referred through the qualified name, consisting of the package name, then a colon, then the name of the symbol. Ex: editor: buffer refers to external symbol buffer accessible in the package named editor.
19. The following four symbol qualifying syntaxes are used: foo: bar look up bar among the external symbols of the package named foo, printed when the symbol bar is external in its home package foo and is not accessible in the current package. foo::bar interns bar as if foo is the current page, printed when symbol bar is internal in its home page foo, and is not accessible in the current page. :bar interns bar as the external symbol in the keyword package and makes it evaluate to itself. Printed if the home page of the symbol bar is keyword. #:bar creates a new uninterned symbol named BAR. Printed when the symbol BAR is uninterented(has no home package )
20. Exporting and Importing Symbols Symbols from one package may be exported to imported from other packages by the use of functions export and import respectively. (import ‘editor:buffer) takes the external symbol named buffer in the editor package and adds it to the current package as an internal symbol. A symbol is said to be shadowed by another symbol in some package if the first symbol would be accessible by inheritance if not for the presence of the second symbol.
21. To import a symbol without the possibility of getting the error because of shadowing use the function shadowing-import. Use package causes a package to inherit all of the external symbols from some other package. Unlike import, use-package does not cause any of the new symbols to be present in the current package, but makes them accessible by inheritance.
22. The function export takes the symbol that is accessible in some specified package, and makes it an external symbol of that package. If the symbol is directly present as an internal symbol, the it is imply changed to external status. If the symbol is accessible via use-package, the symbol is first imported to the package and then exported. If the same name is being used more than once name-conflicts may occur, so care has to be taken to avoid any such name conflicts.
23. Built-in Packages Common lisp built-in packages: Lisp contains the primitives of the common lisp system. Its external symbols include all of the user defined functions such as car, car and *package*. user package is the current package at the time a Common Lisp system starts up. common-lisp package contains the primitives of the ANSI commomLisp system. common-lisp-user is by default the current package at the time, an ANSI common Lisp system starts up.
24. Built-in packages Keyword package contains all the keywords used by built-in or user-defined Lisp functions. System package name is reserved to the implementation. This is used to contain names of implementation-dependent system-interface functions. This package uses lisp and has the nickname sys.
