Cycle de vie d'activité Android et les composant d'AndroidHoussem Lahiani
Chapitre expliquant le cycle de vie d'une activité Android avec une application pour les différentes méthodes formant le cycle de vie de l'Activity.
Il contient aussi quelques exercices sure les composants Android comme les boites de dialogues(AlertDialog) et les case à cocher (RadioButton).
The document describes various data structures and processes used in an ORM (object-relational mapper) system. The key points are:
1. The registry maps model names to model classes and holds metadata. It returns model class instances from browse() which reflect model definitions.
2. The record cache stores field values for quick access and is prefetched and invalidated based on changes.
3. Fields to write collects updates and flushes multiple records with the same updates in a single SQL query to minimize writes.
4. Fields to compute delays computations by tracking which records need recomputation and coordinating with the cache and writes.
5. Field triggers determine what to recompute or invalidate in the
This document provides an overview of Qt animation frameworks, including timers, timelines, the animation framework, state machine framework, and graphics view framework. It describes the key classes used in each framework, such as QTimer for timers, QTimeLine for timelines, QPropertyAnimation for the animation framework, and QGraphicsScene/QGraphicsView for graphics view. Examples are provided for animating a button using each technique.

Social Engineering the Windows Kernel by James ForshawShakacon
One successful technique in social engineering is pretending to be someone or something you're not and hoping the security guard who's forgotten their reading glasses doesn't look too closely at your fake ID. Of course there's no hyperopic guard in the Windows OS, but we do have an ID card, the Access Token which proves our identity to the system and let us access secured resources.
The Windows kernel provides simple capabilities to identify fake Access Tokens, but sometimes the kernel or other kernel-mode drivers are too busy to use them correctly. If a fake token isn't spotted during a privileged operation local elevation of privilege or information disclosure vulnerabilities can be the result. This could allow an attacker to break out of an application sandbox, elevate to administrator privileges or even compromise the kernel itself.
This presentation is about finding and then exploiting the incorrect handling of tokens in the windows kernel as well as first and third party drivers. Examples of serious vulnerabilities such as CVE-2015-0002 and CVE-2015-0062 will be presented. It will provide clear exploitable patterns so that you can do your own security reviews for these issues. Finally I'll discuss some of the ways of exploiting these types of vulnerabilities to elevate local privileges.

Variational이라는 단어로는 아무것도 안떠오릅니다.
그래서, '꿩 대신 닭'이라고 표현해 봤습니다.
초반 독자적인 그림을 통해 개념잡기가 쉬워요.

This document describes an implementation of backpropagation algorithm in C code to understand the backpropagation algorithm through programming. It also explains how it can be applied to a real-world case of handwritten digit recognition using TensorFlow code. The neural network code can be used to gain experience by adjusting values and observing their effects on the network.
To install Python and TensorFlow, download Python version 3.5.2 from the Python website and TensorFlow from the TensorFlow website. Python 3.5.2 must be installed before installing TensorFlow. Once Python is installed, add it to the system PATH and install pip. Then use pip to install various Python packages like iPython, PyQt5, Matplotlib, OpenCV, and Spyder for data science and machine learning.
This document discusses convolutional neural networks (CNNs) for image recognition. It explains key CNN components like convolutional layers, pooling layers, hyperparameters like kernel size and stride. It provides code in TensorFlow to recognize handwritten digits from the MNIST dataset using a CNN model with convolutional and pooling layers. The code trains the model on MNIST data and evaluates test accuracy.
The document discusses interfaces in COM. It explains that interfaces allow invoking functions of COM objects indirectly using virtual function techniques. It shows how to define a pure abstract interface class and have implementation classes inherit the interface. Clients can call interface methods without knowing the underlying implementation class. Later sections discuss adding multiple interfaces to a class, querying for interfaces, and how a client can load and use a COM server from a DLL.
This document discusses the COM (Component Object Model) architecture. It covers topics such as how COM uses the Windows Registry to associate components with their class identifiers (CLSIDs) and locations, how clients can load and interact with servers through functions like CoGetClassObject and CoCreateInstance, how servers implement functions like DllRegisterServer to register themselves, and how interfaces are defined using Interface Definition Language (IDL) and compiled using MIDL. It also compares the COM architecture to web services, noting differences in technologies used like IDL vs WSDL and the Windows Registry vs UDDI for discovery.
신경망의 층이 늘어났을 때 (즉 신경망이 깊어졌을 때), 학습의 어려움을 해소하기 위해 제시된 선행학습 관점에서 DBN과 AE를 소개합니다. 또한 다른 접근법으로 문제를 해소하여 뒤 늦게 심층 신경망으로 간주되고 있는 CNN을 소개합니다.
DBN에 사용된 RBM, AE는 GAN과 더블어 비교사학습 방법을 이끄는 삼두마차입니다. CNN은 영상학습 분야의 단연 절대강자입니다.
산포된 데이터를 정합하는 직선을 찾는 것으로 이해해도 무방합니다. 주어진 데이터를 이용해 기울기와 절편을 구하는 방법입니다.
먼저 행렬연산을 통해 구하는 방법을 설명합니다. 그리고 퍼셉트론에 사용된 것과 같은 방법을 다시 설명하므로 선택적으로 듣기 바랍니다.
설명된 예제에 대한 C 언어 코드를 제공합니다. Tensorlow 코드는 정합 과정을 시각화하여 보여줍니다.

}
윈도우 클래스 부분을 천천히 다시 살펴 봅니다
뒤로 넘어가지 말고 직접 해결 해 보세요 제발!
답을 알았으면 뒤로

신기하게도 고칠 수가 있다
사람은 안 가르쳐 줘도 스스로 할 수 있는 능력이 있어
앞으로도 이런 식으로 합니다

무슨 메시지인지만 구분
메시지 처리 유형 Ⅰ
메시지 처리 유형 번호는 중요하지 않음
유형 5가지를 제시하고 그게 전부라는 것을 전달하고자 유형 번호 부여
사실 5가지도 그냥 정한 거야

WM_MOUSEMOVE
마우스 움직임 이벤트
마우스 좌표는 어디서 가져와야 하지 ?
부가정보 wParam 또는 lParam
int x = HIWORD(lParam)
int y = LOWORD(lParam)
high-order word, low-order word
부가 정보 어느 파라미터에 있고 어떻게 끄집어 내야 할지 외워야 하나 ?
그럴 필요 없다

■ MSDN 사용
MSDN은 대개 Visual C++ 을 설치할 때 함께 설치된다. 이 경우 비주얼
스튜디오에서 F1키를 누르면 현재 커서위치의 문자를 키워드로 하여
MSDN을 실행시킨다. 그렇지 않은 사람은 http://msdn.micorsoft.com/ 을
통해 온라인으로 정보를 찾을 수 있다.
■ MSDN의 메인 화면
본 화 면 의 검 색 창 (Search) 에 WM_MOUSEMOVE 를 입 력 하 고
검색(Search)버튼을 누르면 된다.

■ WM_MOUSEMOVE 검색결과 화면
This message is posted to a window when user moves the mouse while pressing
the left mouse button or moves the stylus while the tip is down. If another
window does not capture the mouse stylus input, the OS posts the message to
the window that contains the cursor or the stylus tip. If another window
captures the mouse or stylus input, the OS posts the message to the window
that has the capture.
WM_MOUSEMOVE
fwKeys = wParam;
xPos = LOWORD(lParam);
yPos = HIWORD(lParam);
Parameters
fwKeys
Indicates the mouse buttons and keys that the user pressed. The following
table shows the possible values, which can be combined.
Value Description
MK_CONTROL The user pressed the CTRL key.
MK_LBUTTON The user pressed the left mouse button.
MK_SHIFT The user pressed the SHIFT key.

윈도우 화면에 글자 출력하기
HDC hdc;
hdc = GetDC(hWnd);
TextOut(hdc, x, y, "hello", 5);
ReleaseDC(hWnd, hdc);
x, y 위치에 “hello” 출력, “hello” 문자열의 길이는 5
근데 hdc 는 뭐야 ?
하여튼 출력되는 문자열은 “hello”라 이거지
18. 18
윈도우 화면에 글자 출력하기는 그냥 이렇게 해
HDC hdc;
hdc = GetDC(hWnd);
TextOut(hdc, x, y, "hello", 5);
ReleaseDC(hWnd, hdc);
hdc는 GetDC 함수를 통해
hWnd가 가리키는 윈도우에서 얻어 오는 것
Device Context 라고 함
HDC GetDC(HWND hWnd)
ReleaseDC(HWND hWnd, HDC hdc) 얻어왔으니 반환해야지
이 둘은 항상 쌍으로

#include <stdio.h>
#include <string.h>
LRESULT CALLBACK WndProc(HWND hWnd, UINT mesg, WPARAM wParam, LPARAM lParam)
{…
case WM_MOUSEMOVE:
int x, y;
char szPos[80];
HDC hdc;
x = LOWORD(lParam);
y = HIWORD(lParam);
sprintf(szPos, "%03d %03d", x, y);
hdc = GetDC(hWnd);
TextOut(0, 0, szPos, strlen(szPos));
ReleaseDC(hWnd, hdc);
break;
…
}
sprintf 함수를 몰랐을 수도 있지만 예제 보니까 별 것 없다
이제 알면 되지
20. 20
정리하면
• WM_XXXX
• WndProc 함수의 case 문에 추가
• 부가정보는 MSDN에서 검색
• 앞으로 어떤 이벤트(메시지)가
있는지 알아보면 되겠죠
