Data Forensics-Tool to display the deleted partition information
1 like565 views
This program displays partition information from a disk image file. It defines a Partition class to store data for each partition, including the start sector, size, and file system type. The program reads in the disk image, extracts the partition table contents using the Partition class, and outputs the number of partitions and details about each partition such as size and file system type.

![Drawbacks:
To calculate the partition in MB, multiplying the partition in sectors by 512,
because sector size is 512 and divide the result by 1MB = 1024 * 1024 Bytes.
To calculate the information correctly, information must be changed to
big_endian format because the format of information is little_endian.

Course: https://talkpython.fm/pythonic
One of the special concepts in Python is the idea of writing idiomatic code that is most aligned with the language features and ideals. In Python, we call this idiomatic code Pythonic. While this idea is easy to understand, it turns out to be fairly hard to make concrete.
In this webcast, Michael Kennedy from the Talk Python To Me podcast will take you on a tour of 10 of the more popular and useful code examples demonstrating examples of Pythonic code. In the examples, you'll first see non-Pythonic code and then the more natural Pythonic version.
Topics covered include the expansive use of dictionaries, hacking Python's memory usage via slots, using generators, comprehensions, and generator expressions, creating subsets of collections via slices (all the way to the database) and more. Several of these are Python 3 features so you'll have even more reason to adopt Python 3 for your next project.

The document discusses various Python magic methods that can be overridden in classes to customize behavior. It provides examples of overriding __contains__, __getitem__, __len__, and __nonzero__ methods to change how membership testing, item access, length calculation, and truth value testing work for class instances. The examples demonstrate how these magic methods allow flexible, customized behavior compared to regular classes and built-in types.CiIC4010-chapter-2-f17

Teams offer an alternative approach to organizing employees compared to a traditional vertical hierarchy. Teams are made up of two or more people working together to achieve common goals, and can lead to increased employee motivation and business productivity. Effective teamwork requires members to not only share information but also share responsibility for the team's work in order to achieve synergy and accomplish more together than individually. Teamwork skills are important to develop to be able to obtain success in both business and education. Building a successful team requires selecting a leader who can understand each member's needs and expectations to motivate the team working as one toward shared objectives and goals.Computer forensics

This document discusses the Dynamic Host Configuration Protocol (DHCP). DHCP allows devices on a network to obtain IP addresses and other network configuration information automatically from a DHCP server. It is a client-server protocol that involves 4 steps: discovery of the DHCP server, offers of IP addresses from one or more servers, a request from the client for a specific offered address, and an acknowledgment from the server with the assigned address. DHCP simplifies network administration by automating the assignment of IP addresses and configuration settings to devices on the network.What is tackled in the Java EE Security API (Java EE 8)

Step 1: Requirements: An Address Database
Create a C++ console application that will store and retrieve names and addresses in a text file.
The program should do the following.
1. It should accept a series of names and addresses from the console.
2. The user's input should be written to a text file in the CSV format described in the lesson, but do not include the field names in the first row of the file. Use a delimiter to separate the records.
3. Read the records from the text file, and display them in a user-friendly format.
4. Provide a menu to allow the user to append records to the file, display the records, or exit the application.
Build upon the code below to complete the assignment.

The document discusses Binee, an emulator that extends existing PE emulators by mocking Windows functions, system calls, and OS subsystems to enable deeper malware analysis. It loads PE files and DLLs, resolves imports, and maps them into emulated memory. Binee defines hooks for functions to intercept calls and interact with mocked subsystems for file I/O, registry, memory, and other OS services. Configuration files define the emulated OS environment to provide context and rapidly change configurations for analysis. This approach aims to reduce the cost of dynamic analysis while extracting more features through emulation at scale.Why learn Internals?

1. How ArrayList and StringBuilder work internally using arrays and memory copying as the size increases. This can lead to inefficient memory usage.
2. How inner classes are implemented by compilers by generating additional accessor methods, increasing method count and affecting optimizations.
3. How the Android zygote process improves startup and memory usage by loading the framework once and sharing it across apps.
4. How the CPU cache works and how optimizing code to improve cache locality can significantly increase performance despite doing less work.

eZ Cluster allows running an eZ Publish installation on multiple servers for improved performance, redundancy, and scalability. It matches the database storage for metadata with either database or network file system storage for content files. The cluster handlers store metadata in the database and files either in the database or on an NFS server. Configuration involves setting the cluster handler, storing files on the database or NFS, moving existing files to the cluster, rewriting URLs, and indexing binary files. The cluster API provides methods for reading, writing, and caching files while handling concurrency and stale caching.Introduction to Data Structures, Data Structures using C.pptx

Apache ANT is a Java-based build tool that allows developers to compile, test, and manage Java applications. It uses XML files to describe and control build processes in a platform-independent manner. Key features of ANT include being open source, operating system independent, requiring only a JVM to run, and allowing tasks to be easily extended with Java. The typical structure of an ANT build file includes a project element containing target elements which hold task elements. Common tasks include compiling code, zipping/unzipping files, executing system commands, and sending emails.Z OS IBM Utilities

It is a client-server protocol that involves 4 steps: discovery of the DHCP server, offers of IP addresses from one or more servers, a request from the client for a specific offered address, and an acknowledgment from the server with the assigned address. DHCP simplifies network administration by automating the assignment of IP addresses and configuration settings to devices on the network.What is tackled in the Java EE Security API (Java EE 8)

The Java EE Security API (JSR-375) wants to simplify the implementation of security-related features in your Java EE application. Application server specific configuration changes will be no longer needed and things will be much more app developer friendly. Aligning security with the ease of development we saw in the recent version of Java EE. We will show you the basic goals and concepts behind Java EE Security API. And of course, demos with the current version of the RI, named Soteria, how you can do Authentication and Authorization.Similar to Data Forensics-Tool to display the deleted partition information (20)

Lab:
Step 1: Requirements: An Address Database
Create a C++ console application that will store and retrieve names and addresses in a text file.
The program should do the following.
1. It should accept a series of names and addresses from the console.
2. The user's input should be written to a text file in the CSV format described in the lesson, but do not include the field names in the first row of the file. Use a delimiter to separate the records.
3. Read the records from the text file, and display them in a user-friendly format.
4. Provide a menu to allow the user to append records to the file, display the records, or exit the application.
Build upon the code below to complete the assignment.
//Specification: Append and display records in a address database

The document discusses Binee, an emulator that extends existing PE emulators by mocking Windows functions, system calls, and OS subsystems to enable deeper malware analysis. It loads PE files and DLLs, resolves imports, and maps them into emulated memory. Binee defines hooks for functions to intercept calls and interact with mocked subsystems for file I/O, registry, memory, and other OS services. Configuration files define the emulated OS environment to provide context and rapidly change configurations for analysis. This approach aims to reduce the cost of dynamic analysis while extracting more features through emulation at scale.Why learn Internals?

The document discusses several Java and Android internals topics:
1. How ArrayList and StringBuilder work internally using arrays and memory copying as the size increases. This can lead to inefficient memory usage.
2. How inner classes are implemented by compilers by generating additional accessor methods, increasing method count and affecting optimizations.
3. How the Android zygote process improves startup and memory usage by loading the framework once and sharing it across apps.
4. How the CPU cache works and how optimizing code to improve cache locality can significantly increase performance despite doing less work.
5. Issues like memory fragmentation that can occur if the Android garbage collector and compactor are unable to run due to the app beingFI MUNI 2012 - iOS Basics

eZ Cluster allows running an eZ Publish installation on multiple servers for improved performance, redundancy, and scalability. It matches the database storage for metadata with either database or network file system storage for content files. The cluster handlers store metadata in the database and files either in the database or on an NFS server. Configuration involves setting the cluster handler, storing files on the database or NFS, moving existing files to the cluster, rewriting URLs, and indexing binary files. The cluster API provides methods for reading, writing, and caching files while handling concurrency and stale caching.Introduction to Data Structures, Data Structures using C.pptx

Apache ANT is a Java-based build tool that allows developers to compile, test, and manage Java applications. It uses XML files to describe and control build processes in a platform-independent manner. Key features of ANT include being open source, operating system independent, requiring only a JVM to run, and allowing tasks to be easily extended with Java. The typical structure of an ANT build file includes a project element containing target elements which hold task elements. Common tasks include compiling code, zipping/unzipping files, executing system commands, and sending emails.Z OS IBM Utilities

Question IYou are going to use the semaphores for process sy.docxaudeleypearl
油
Question I
You are going to use the semaphores for process synchronization. Therefore, you are asked to develop a consumer and producer multithreaded program.
Let us assume, that we have a thread (producer, we will call it producer_thread) reading data (positive integer numbers) from the keyboard, entered by a user to be stored in an array (dynamic array). (Assume that the array can hold all numbers entered without overflow.)
Another thread (consumer, we will call it consumer_thread) should read data from the array and write them into a file. This thread should run concurrently with the producer (producer_thread).
Your program should make sure that the consumer_thread can read from the array only after the producer_thread has stored new data. Both threads will stop when the user enters a negative number (well synchronized).
Another thread (testing_thread) should start reading the array data as well as the file data and display them on the screen in order to verify if the consumer and producer have worked in a correctly synchronized fashion. This thread should not be synchronized with other threads, it is intended for testing that consumer thread is synchronized with produce thread.
Provide your tutor with the source code as well as screen snapshots that show the work of the testing_thread.

This document provides instructions for a lab assignment to create a C++ program that stores and retrieves address records from a sequential text file. The program is meant to accept user input of multiple names and addresses, write them to a CSV formatted file, read the records back from the file and display them in a formatted manner. The lab steps guide the user to build upon example code provided to develop the program's processing logic and menu system using pseudocode. They are then instructed to create and compile the C++ project, test and debug it, and provide screenshots of the output and source code in a Word document for submission.Data Forensics-Tool to display the deleted partition information
- 1. Title : Tool to display the partition information only Name : Shivakumar Koppad ID : 14043513 Date : 06/03/2015 Module code : EE6012 Lecturer : Dr. Donal Heffernan Assignment#1 Requirements : This program was created by using Microsoft Visual C++ 2010. Class for the partition table was defined in order to restores information about partitions, to configure the location of the first byte of the partition Information and to copy the contents of an array from the memory cache to the private member array. Features that were implemented: There are four features that were implemented in this program: 1- The number of partitions on the disk is represented. 2- The start sector of the partition is represented. 3- The file system type of the partition is represented. 4- The size of the partition in sectors in MB is represented. Testing and Result: 1- The source code EE6012_phase1 was created and implemented. 2- The new folder which named Shiva was created in the local Disk(E:). 3- The executed file in the debug in Shiva.exe was copied and pasted in Shiva in order to read the image. 4- The Sample_1.dd image file was used in Shiva. 5- Program is implemented in a command window by going to the right path (E: Shiva >) and typing (Shiva.exe Sample_1.dd) Instructions for running the program: 1. The executable file Shiva.exe was created. 2. The folder called Shiva was created in the local Disk(E:). 3. Copied the executable file Shiva.exe (found in Debug folder and Sample_1.dd and put them in Shiva in the local Disk(E:). 4. Implement the program in the command window by going to the right path (E: Shiva >) and typing (Shiva.exe Sample_1.dd)
- 2. Drawbacks: To calculate the partition in MB, multiplying the partition in sectors by 512, because sector size is 512 and divide the result by 1MB = 1024 * 1024 Bytes. To calculate the information correctly, information must be changed to big_endian format because the format of information is little_endian.
