Incorporating site level knowledge to extract structured data from web forums...George Ang
The document discusses extracting structured data from web forums. It proposes leveraging more site-level knowledge such as the forum sitemap and page layouts to improve data extraction. Template-based clustering is used to group similar forum pages. Relationships between elements on pages and across pages are also analyzed. Structured data like posts and threads are extracted using formulas defined in a Markov logic network model that takes advantage of the site structure and element relationships. Experiments demonstrate the approach can accurately extract author, title, time and content from forum posts and threads.

Why You Should Replace Windows 11 with Nitrux Linux 3.5.0 for enhanced perfor...SOFTTECHHUB
The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.
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.

The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

31. Communication and MVC
• How should objects communicate?
• Which objects know about one another?
• Controller
• Knows about model and view objects
• The brains of the operation
• Manages relationships and data flow
• Typically app-specific, Controller
so rarely reusable

36. Problem: Managing a Screenful
• Controller manages views, data and application logic
• Apps are made up of many of these
• Would be nice to have a well-defined starting point
■ A la UIView for views
■ Common language for talking about controllers

37. Problem: Building Typical Apps
• Some application flows are very common
■ Navigation-based
■ Tab bar-based
■ Combine the two
• Don’t reinvent the wheel
• Plug individual screens together to build an app

38. UIViewController
• Basic building block
• Manages a screenful of content
• Subclass to add your application logic

41. “Your” and “Our” View Controllers
• Create your own UIViewController subclass for each screenful
• Plug them together using existing composite view controllers

#import <UIKit/UIKit.h>
@interface MyViewController : UIViewController {
// A view controller will usually
// manage views and data
NSMutableArray *myData;
UILabel *myLabel;
}

@interface MyViewController : UIViewController {

UILabel *myLabel;
}
// Expose some of its contents to clients
@property (readonly) NSArray *myData;

// Expose some of its contents to clients
@property (readonly) NSArray *myData;

48. The “View” in “View Controller”
Friday, January 22, 2010 27
49. The “View” in “View Controller”
• UIViewController superclass has a view property
■ @property (retain) UIView *view;
Friday, January 22, 2010 27
50. The “View” in “View Controller”
• UIViewController superclass has a view property
■ @property (retain) UIView *view;
• Loads lazily
■ On demand when requested
■ Can be purged on demand as well (low memory)

51. The “View” in “View Controller”
• UIViewController superclass has a view property
■ @property (retain) UIView *view;
• Loads lazily
■ On demand when requested
■ Can be purged on demand as well (low memory)
• Sizing and positioning the view?
■ Depends on where it’s being used
■ Don’t make assumptions, be flexible

53. When to call -loadView?
• Don’t do it!

54. When to call -loadView?
• Don’t do it!
• Cocoa tends to embrace a lazy philosophy
■ Call -release instead of -dealloc
■ Call -setNeedsDisplay instead of -drawRect:

55. When to call -loadView?
• Don’t do it!
• Cocoa tends to embrace a lazy philosophy
■ Call -release instead of -dealloc
■ Call -setNeedsDisplay instead of -drawRect:
• Allows work to be deferred or coalesced
■ Performance!

MyView *myView = [[MyView alloc] initWithFrame:frame];
self.view = myView; // The view controller now owns the view
[myView release];
