This document discusses the design of a Unity3D Audio Grabber tool that records audio from Unity3D games. It explains that the tool will link with the FMOD Ex library and hook certain FMOD functions, like FMOD_System_Create, to get the FMOD system object and manipulate FMOD audio. It will then take the audio buffer data and encode it along with video into an .MP4 file using MediaCodec. The tool is designed to work similarly to how another tool called libkamcordaudio grabs audio in Unity3D games.

Binding Objective-C Libraries, Miguel de Icaza
This document discusses how to create bindings between Objective-C and C# code using Xamarin.iOS. It covers when to create bindings, how the binding process works, and ways to improve bindings. Key points include:
- Bindings allow existing Objective-C/C code and libraries to be consumed from C# in Xamarin.iOS apps. They map Objective-C APIs and objects to equivalent C# interfaces and classes.
- The binding process involves generating C# interfaces that map to Objective-C headers, then building a binding library that surfaces the native APIs in C#.
- Features like notifications, properties, enums and structures are discussed. Advanced topics cover improving bindings through extensions, strong

Plug-ins & Third-Party SDKs in UE4
Overview of the basics of modules, plug-ins and projects in UE4, and a deep dive into integrating third-party dependencies. Presented at MIGS 2016 in Montreal.
Pharo foreign function interface (FFI) by example by Esteban Lorenzano
Since Pharo 5 we have been developing a new framework for communicate with external libraries called UnifiedFFI (or UFFI) that has opened the doors to perform a huge step in our support for mainstream necessities. In this talk I will talk about the intrinsic problems of developing such frameworks and put it in practice through the example of the newest tool in the Pharo family: Iceberg (the git client).
Reproducibility and automation of machine learning process
A speech about organization of machine learning process in practice. Conceptual and technical aspects discussed. Introduction into Luigi framework. A short story about neural networks fitting in Flo - top-level mobile tracker of women health.
Autotools pratical training
The document discusses the autotools process. It explains that autotools is a collection of tools including Automake, Autoconf, Libtool, and others. The process involves generating files from templates, including generating a configure script from configure.ac and Makefile.in files from Makefile.am. Developers manage these template files. The process then involves running configure, make, and make install to build and install the software. Debugging is also discussed.
Pharo 64bits
This document discusses Pharo moving to 64-bit support. It notes that 64-bit is now standard, applications may need over 2GB memory, and not all libraries support 32-bit. It describes work by the OpenSmalltalk-VM team to implement a 64-bit JIT for various platforms. Pharo 6.0 integrated 32-bit images that create 64-bit images, while Pharo 7.0 will directly bootstrap 64-bit images. FFI and UFFI adaptations for 64-bit differences like structure sizes and long types between platforms are discussed. Potential migration issues are also outlined.
Golang
Go is an open source programming language designed by Google to be concurrent, garbage collected, and efficient. It has a simple syntax and is used by Google and others to build large distributed systems. Key features include garbage collection, concurrency with goroutines and channels, interfaces without inheritance, and a large standard library.
3 Git
The Information Technology have led us into an era where the production, sharing and use of information are now part of everyday life and of which we are often unaware actors almost: it is now almost inevitable not leave a digital trail of many of the actions we do every day; for example, by digital content such as photos, videos, blog posts and everything that revolves around the social networks (Facebook and Twitter in particular). Added to this is that with the "internet of things", we see an increase in devices such as watches, bracelets, thermostats and many other items that are able to connect to the network and therefore generate large data streams. This explosion of data justifies the birth, in the world of the term Big Data: it indicates the data produced in large quantities, with remarkable speed and in different formats, which requires processing technologies and resources that go far beyond the conventional systems management and storage of data. It is immediately clear that, 1) models of data storage based on the relational model, and 2) processing systems based on stored procedures and computations on grids are not applicable in these contexts. As regards the point 1, the RDBMS, widely used for a great variety of applications, have some problems when the amount of data grows beyond certain limits. The scalability and cost of implementation are only a part of the disadvantages: very often, in fact, when there is opposite to the management of big data, also the variability, or the lack of a fixed structure, represents a significant problem. This has given a boost to the development of the NoSQL database. The website NoSQL Databases defines NoSQL databases such as "Next Generation Databases mostly addressing some of the points: being non-relational, distributed, open source and horizontally scalable." These databases are: distributed, open source, scalable horizontally, without a predetermined pattern (key-value, column-oriented, document-based and graph-based), easily replicable, devoid of the ACID and can handle large amounts of data. These databases are integrated or integrated with processing tools based on the MapReduce paradigm proposed by Google in 2009. MapReduce with the open source Hadoop framework represent the new model for distributed processing of large amounts of data that goes to supplant techniques based on stored procedures and computational grids (step 2). The relational model taught courses in basic database design, has many limitations compared to the demands posed by new applications based on Big Data and NoSQL databases that use to store data and MapReduce to process large amounts of data.

Git for Excel
When dealing with critical Excel workbooks, you want to have proper source control in place. This presentation is about the different challenges we face when using Git with Excel files and how we can solve them by using the right mix of settings, extensions and Git workflow.
Package management and creation in Gentoo Linux
Gentoo Linux uses Portage for package management and software installation. Portage allows for compiling packages from source code with customizable build options. It features USE flags to selectively include features, parallel builds, binary package support, and tools that make maintenance and upgrades easy. Ebuilds define how to build and install packages and have evolved through several EAPI stages to support new features.
Go & multi platform GUI Trials and Errors
This document summarizes Yoshiki Shibukawa's presentation on building multi-platform GUI applications with Go. Shibukawa explored several approaches: wrapping existing toolkits, creating a new toolkit in Go, and a hybrid C++/Go approach. While wrapping toolkits is intuitive, maintaining wrappers is difficult. Creating a new toolkit in Go allows perfect integration but supporting multiple platforms is challenging. The hybrid approach uses C++ for GUI with Go handling logic, which provides better integration but requires managing inter-process communication. Shibukawa concluded more work is needed to find the best solution and that GUI programming remains difficult, potentially requiring C++ involvement.

Building a Cross-Platform Mobile SDK in Rust.pdf
This document discusses building a cross-platform mobile SDK in Rust. It introduces UniFFI, an open-source binding generator that produces idiomatic bindings for Swift, Kotlin, and other languages from an Interface Definition Language file. While cross-compilation for iOS is straightforward, Android requires configuring linker paths. Shipping the library also requires additional steps like creating a framework and dealing with platform-specific quirks in Swift and Android. Open questions remain around repository structure, build systems, and exploring Android further. Resources for UniFFI and compiling Rust for Android are provided.
44CON London 2015 - Reverse engineering and exploiting font rasterizers: the ...
A stack-based buffer overflow vulnerability was discovered in FreeType's CFF rasterizer during fuzz testing. The vulnerability occurs when building the hintmap data structure in the cf2_hintmap_build function. By analyzing the source code, it appears the vulnerability is caused by insufficient bounds checking when accessing the hint mask array via the maskPtr pointer, allowing writes beyond the end of the allocated buffer. This highlights the ongoing need to fuzz test font parsing libraries given the complexity of font formats and opportunity for security issues.
Static PIE, How and Why - Metasploit's new POSIX payload: Mettle
This talk discusses methods for building and injecting position-independent payloads into ELF processes. It also introduces Metasploit's new POSIX payload 'mettle' and outlines goals and future directions for Unix and Linux exploitation with Metasploit.
Unit i
OOPs provides several benefits like reduced complexity, reusability of code, and less redundancy. It achieves this through concepts like encapsulation, inheritance and polymorphism. Some disadvantages are a steeper learning curve, larger program size and slower execution compared to procedural programming. OOPs can be applied in areas like databases, simulation, web applications and user interfaces. C++ is an object-oriented language that builds upon C with additional features like classes, function overloading and exception handling. It requires a C++ compiler to translate the code to an executable file.

13th kandroid OpenGL and EGL
This document provides information about OpenGL and EGL. It discusses OpenGL concepts like the rendering pipeline, shaders, and GLSL. It explains how to use OpenGL and GLSL on Android, including initializing, creating shaders, and rendering. It also covers EGL and how it acts as an interface between OpenGL and the native platform. It describes EGL objects like displays, surfaces, and contexts. It provides examples of basic EGL usage and lists EGL APIs for initializing, configuring, and managing graphics resources.
Android RenderScript
RenderScript is a high-performance computation API that allows apps to run operations with automatic parallelization across CPU and GPU cores. It provides access to these features without needing to write code for different architectures or processor types. RenderScript code is compiled at runtime, so apps do not need to be recompiled for different devices. The document provides an overview of RenderScript and its system, basic usage, entry points, variables, pointers, memory management, and comparisons with OpenGL ES. It also includes examples of using RenderScript for single-image sampling, multi-image sampling, multi-pass effects, and generating a histogram.
OpenGL ES EGL Spec&APIs
EGL is a native platform interface that provides a connection between OpenGL ES and the underlying native platform window system. It handles graphics context management, surface binding, and synchronization to enable high-performance 2D and 3D rendering using OpenGL ES. The basic usage of EGL involves initializing a display, configuring it, creating surfaces and a context, making the context current, rendering with OpenGL ES, and flushing buffers.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Unity3D Audio Grabber design
- 1. Unity3D Audio Grabber design Unity3D is tested on version 4.6 Jungsoo Nam namjungsoo@gmail.com 2015/03/17
- 2. FMOD Ex • Libunity.so uses FMOD Ex statically(with .c sources or .a archive) linked. • NOT uses libfmodex.so • NOT will be applied by function hooking with Elf32_Ehdr like eglSwapBuffers()’s method. • C++ based library, but C wrapper classes. • C functions can be hooked.
- 3. IDA analysis – libunity.so • ONLY Imports tab’s functions can be hooked. FMOD’s are in Exports tab. (Function pointers are NOT in imports entry table.)
- 4. FMOD hooking • FMOD C API hooking is essential.(libkamcordaudio.so does like this) • Getting/sharing FMOD system object is important for interoperating AudioGrabber with Unity3D FMOD audio. • So we have to hook FMOD_System_Create(FMOD_SYSTEM** system) • How to hook FMOD? • Find another entry table.(exports table) • In VideoGrabber, we found imports table.(libunity.so imports libGLES*.so function) • Next we have to find exports table.(libunity.so exports some functions to client) • Or use “dlsym()” again. • orig_FMOD_System_Create = dlsym(RTLD_DEFAULT, "FMOD_System_Create"); • LOGD("FMOD_System_Create: 0x%x", orig_FMOD_System_Create);
- 5. Final AudioGrabber design • AudioGrabber will be like below: • Link libfmodex.so. • Hook some FMOD functions and get FMOD system object. • Use our FMOD functions in libfmodex.so, manipulate FMOD audio and get audio buffer data. • Put audio buffer data into MediaCodec. • Mix and encode video and audio to .MP4
- 6. Thank you
