• GCC ICE -- alternative function syntax, variadic templates and tuples

  - by Marc H.

  (Related to C++0x, How do I expand a tuple into variadic template function arguments?.) The following code (see below) is taken from this discussion. The objective is to apply a function to a tuple. I simplified the template parameters and modified the code to allow for a return value of generic type. While the original code compiles fine, when I try to compile the modified code with GCC 4.4.3, g++ -std=c++0x main.cc -o main GCC reports an internal compiler error (ICE) with the following message: main.cc: In function ‘int main()’: main.cc:53: internal compiler error: in tsubst_copy, at cp/pt.c:10077 Please submit a full bug report, with preprocessed source if appropriate. See <file:///usr/share/doc/gcc-4.4/README.Bugs> for instructions. Question: Is the code correct? or is the ICE triggered by illegal code? // file: main.cc #include <tuple> // Recursive case template<unsigned int N> struct Apply_aux { template<typename F, typename T, typename... X> static auto apply(F f, const T& t, X... x) -> decltype(Apply_aux<N-1>::apply(f, t, std::get<N-1>(t), x...)) { return Apply_aux<N-1>::apply(f, t, std::get<N-1>(t), x...); } }; // Terminal case template<> struct Apply_aux<0> { template<typename F, typename T, typename... X> static auto apply(F f, const T&, X... x) -> decltype(f(x...)) { return f(x...); } }; // Actual apply function template<typename F, typename T> auto apply(F f, const T& t) -> decltype(Apply_aux<std::tuple_size<T>::value>::apply(f, t)) { return Apply_aux<std::tuple_size<T>::value>::apply(f, t); } // Testing #include <string> #include <iostream> int f(int p1, double p2, std::string p3) { std::cout << "int=" << p1 << ", double=" << p2 << ", string=" << p3 << std::endl; return 1; } int g(int p1, std::string p2) { std::cout << "int=" << p1 << ", string=" << p2 << std::endl; return 2; } int main() { std::tuple<int, double, char const*> tup(1, 2.0, "xxx"); std::cout << apply(f, tup) << std::endl; std::cout << apply(g, std::make_tuple(4, "yyy")) << std::endl; } Remark: If I hardcode the return type in the recursive case (see code), then everything is fine. That is, substituting this snippet for the recursive case does not trigger the ICE: // Recursive case (hardcoded return type) template<unsigned int N> struct Apply_aux { template<typename F, typename T, typename... X> static int apply(F f, const T& t, X... x) { return Apply_aux<N-1>::apply(f, t, std::get<N-1>(t), x...); } }; Alas, this is an incomplete solution to the original problem.

• 3D Graphics with XNA Game Studio 4.0 bug in light map?

  - by Eibis

  i'm following the tutorials on 3D Graphics with XNA Game Studio 4.0 and I came up with an horrible effect when I tried to implement the Light Map http://i.stack.imgur.com/BUWvU.jpg this effect shows up when I look towards the center of the house (and it moves with me). it has this shape because I'm using a sphere to represent light; using other light shapes gives different results. I'm using a class PreLightingRenderer: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Graphics; using Dhpoware; using Microsoft.Xna.Framework.Content; namespace XNAFirstPersonCamera { public class PrelightingRenderer { // Normal, depth, and light map render targets RenderTarget2D depthTarg; RenderTarget2D normalTarg;

// Load effects depthNormalEffect = Content.Load<Effect>(@"Effects\PPDepthNormal"); lightingEffect = Content.Load<Effect>(@"Effects\PPLight"); // Set effect parameters to light mapping effect lightingEffect.Parameters["viewportWidth"].SetValue(viewWidth);

// Calculate the world * view * projection matrix and set it to // the effect Matrix wvp = (Matrix.CreateScale(light.Attenuation) * Matrix.CreateTranslation(light.Position)) * viewProjection; lightingEffect.Parameters["WorldViewProjection"].SetValue(wvp); // Determine the distance between the light and camera float dist = Vector3.Distance(Camera.Position, light.Position); // If the camera is inside the light-sphere, invert the cull mode // to draw the inside of the sphere instead of the outside if (dist < light.Attenuation) graphicsDevice.RasterizerState = RasterizerState.CullClockwise; // Draw the point-light-sphere lightMesh.Meshes[0].Draw(); // Revert the cull mode graphicsDevice.RasterizerState = RasterizerState.CullCounterClockwise; } // Revert the blending and depth render states graphicsDevice.BlendState = BlendState.Opaque;

Any help is very appreciated, thank you for reading!

  I've been learning how to NOP functions in C++ or even C but there are very few tutorials online about it. I've been googling for the past few hours now and I'm just stuck. Here is my code. #include <iostream> #include <windows.h> #include <tlhelp32.h> using namespace std; //#define NOP 0x90 byte NOP[] = {0x90}; void enableDebugPrivileges() { HANDLE hcurrent=GetCurrentProcess(); HANDLE hToken; BOOL bret=OpenProcessToken(hcurrent,40,&hToken); LUID luid; bret=LookupPrivilegeValue(NULL,"SeDebugPrivilege",&luid); TOKEN_PRIVILEGES NewState,PreviousState; DWORD ReturnLength; NewState.PrivilegeCount =1; NewState.Privileges[0].Luid =luid; NewState.Privileges[0].Attributes=2; AdjustTokenPrivileges(hToken,FALSE,&NewState,28,&PreviousState,&ReturnLength); } DWORD GetProcId(char* ProcName) { PROCESSENTRY32 pe32; HANDLE hSnapshot = NULL; pe32.dwSize = sizeof( PROCESSENTRY32 ); hSnapshot = CreateToolhelp32Snapshot( TH32CS_SNAPPROCESS, 0 ); if( Process32First( hSnapshot, &pe32 ) ) { do{ if( strcmp( pe32.szExeFile, ProcName ) == 0 ) break; }while( Process32Next( hSnapshot, &pe32 ) ); } if( hSnapshot != INVALID_HANDLE_VALUE ) CloseHandle( hSnapshot ); return pe32.th32ProcessID; } void WriteMem(DWORD Address, void* Value, size_t Size) { DWORD Protect = NULL; VirtualProtect((LPVOID)Address, 3, PAGE_READWRITE, &Protect); memcpy((void*)Address, Value, 3); VirtualProtect((LPVOID)Address, 3, Protect, &Protect); } void nop_(PVOID address, int bytes){ DWORD d, ds; VirtualProtect(address, bytes, PAGE_EXECUTE_READWRITE, &d); memset(address, 144, bytes); VirtualProtect(address,bytes,d,&ds); } void MemCopy(HANDLE pHandle, void* Dest, const void* Src, int Len) { DWORD OldProtect; DWORD OldProtect2; VirtualProtect(Dest, Len, PAGE_EXECUTE_READWRITE, &OldProtect); memcpy(Dest, Src, Len); VirtualProtect(Dest, Len, OldProtect, &OldProtect2); FlushInstructionCache(pHandle, Dest, Len); } int main() { enableDebugPrivileges(); DWORD pid; HANDLE phandle; // Obtain the process ID pid = GetProcId("gr.exe"); if(GetLastError()) { cout << "Error_PID_: " << GetLastError() << endl; system("pause"); return -1; } // Obtain the process handle phandle = OpenProcess(PROCESS_ALL_ACCESS,0,pid); if(GetLastError()) { cout << "Error_HANDLE_: " << GetLastError() << endl; system("pause"); return -1; } // Debug info, 0 = bad cout <<"pid : " << pid << endl; cout <<"HANDLE: " << phandle << endl << endl; system("pause"); // Change value to short iValue = -1; int choice = 0; BYTE * bGodMode = (BYTE *) (0x409A7E); // Lives Address bool hack = true; while(hack) { system("cls"); cout << "What hack?\n0. Exit\n1. Lives\n\n!> "; cin >> choice; switch(choice) { case 0: { hack=false; break; } case 1: // Modify Time cout << "God Mode On\n!> "; // cin >> iValue; // nop_((PVOID)(0x409A7E), 3); // MemCopy(phandle, (PVOID)0x409A7E, &NOP, 1); WriteMem((DWORD)(0x00409A7E), (void*)NOP, sizeof NOP); if(GetLastError()) { cout << "Error: " << GetLastError() << endl; system("pause"); } break; default: cout << "ERROR!\n"; break; } Sleep(100); } system("pause"); return 0; } This is suppose to NOP the DEC function that is 3 bytes long preventing me from losing lives. However each time I try it, it crashes the hack and says I had a access violation. I tried to look up the reasons and most of them dealt with with the size of the location I'm writing to and what I'm copying from. Otherwise, I have absolutely no idea. Any help would be nice. The game is GunRoar and the base address "0x409A7E" is where the DEC function is.

• More elegant way to make a C++ member function change different member variables based on template p

  - by Eric Moyer

  Today, I wrote some code that needed to add elements to different container variables depending on the type of a template parameter. I solved it by writing a friend helper class specialized on its own template parameter which had a member variable of the original class. It saved me a few hundred lines of repeating myself without adding much complexity. However, it seemed kludgey. I would like to know if there is a better, more elegant way. The code below is a greatly simplified example illustrating the problem and my solution. It compiles in g++. #include <vector> #include <algorithm> #include <iostream> namespace myNS{ template<class Elt> struct Container{ std::vector<Elt> contents; template<class Iter> void set(Iter begin, Iter end){ contents.erase(contents.begin(), contents.end()); std::copy(begin, end, back_inserter(contents)); } }; struct User; namespace WkNS{ template<class Elt> struct Worker{ User& u; Worker(User& u):u(u){} template<class Iter> void set(Iter begin, Iter end); }; }; struct F{ int x; explicit F(int x):x(x){} }; struct G{ double x; explicit G(double x):x(x){} }; struct User{ Container<F> a; Container<G> b; template<class Elt> void doIt(Elt x, Elt y){ std::vector<Elt> v; v.push_back(x); v.push_back(y); Worker<Elt>(*this).set(v.begin(), v.end()); } }; namespace WkNS{ template<class Elt> template<class Iter> void Worker<Elt>::set(Iter begin, Iter end){ std::cout << "Set a." << std::endl; u.a.set(begin, end); } template<> template<class Iter> void Worker<G>::set(Iter begin, Iter end){ std::cout << "Set b." << std::endl; u.b.set(begin, end); } }; }; int main(){ using myNS::F; using myNS::G; myNS::User u; u.doIt(F(1),F(2)); u.doIt(G(3),G(4)); } User is the class I was writing. Worker is my helper class. I have it in its own namespace because I don't want it causing trouble outside myNS. Container is a container class whose definition I don't want to modify, but is used by User in its instance variables. doIt<F> should modify a. doIt<G> should modify b. F and G are open to limited modification if that would produce a more elegant solution. (As an example of one such modification, in the real application F's constructor takes a dummy parameter to make it look like G's constructor and save me from repeating myself.) In the real code, Worker is a friend of User and member variables are private. To make the example simpler to write, I made everything public. However, a solution that requires things to be public really doesn't answer my question. Given all these caveats, is there a better way to write User::doIt?

• Multiset of shared_ptrs as a dynamic priority queue: Concept and practice

  - by Sarah

  I was using a vector-based priority queue typedef std::priority_queue< Event, vector< Event >, std::greater< Event > > EventPQ; to manage my Event objects. Now my simulation has to be able to find and delete certain Event objects not at the top of the queue. I'd like to know if my planned work-around can do what I need it to, and if I have the syntax right. I'd also like to know if dramatically better solutions exist. My plan is to make EventPQ a multiset of smart pointers to Event objects: typedef std::multi_set< boost::shared_ptr< Event > > EventPQ; I'm borrowing functions of the Event class from a related post on a multimap priority queue. // Event.h #include <cstdlib> using namespace std; #include <set> #include <boost/shared_ptr.hpp> class Event; typedef std::multi_set< boost::shared_ptr< Event > > EventPQ; class Event { public: Event( double t, int eid, int hid ); ~Event(); void add( EventPQ& q ); void remove(); bool operator < ( const Event & rhs ) const { return ( time < rhs.time ); } bool operator > ( const Event & rhs ) const { return ( time > rhs.time ); } double time; int eventID; int hostID; EventPQ* mq; EventPQ::iterator mIt; }; // Event.cpp Event::Event( double t, int eid, int hid ) { time = t; eventID = eid; hostID = hid; } Event::~Event() {} void Event::add( EventPQ& q ) { mq = &q; mIt = q.insert( boost::shared_ptr<Event>(this) ); } void Event::remove() { mq.erase( mIt ); mq = 0; mIt = EventPQ::iterator(); } I was hoping that by making EventPQ a container of pointers, I could avoid wasting time copying Events into the container and avoid accidentally editing the wrong copy. Would it be dramatically easier to store the Events themselves in EventPQ instead? Does it make more sense to remove the time keys from Event objects and use them instead as keys in a multimap? Assuming the current implementation seems okay, my questions are: Do I need to specify how to sort on the pointers, rather than the objects, or does the multiset automatically know to sort on the objects pointed to? If I have a shared_ptr ptr1 to an Event that also has a pointer in the EventPQ container, how do I find and delete the corresponding pointer in EventPQ? Is it enough to .find( ptr1 ), or do I instead have to find by the key (time)? Is the Event::remove() sufficient for removing the pointer in the EventPQ container? There's a small chance multiple events could be created with the same time (obviously implied in the use of multiset). If the find() works on event times, to avoid accidentally deleting the wrong event, I was planning to throw in a further check on eventID and hostID. Does this seem reasonable? (Dumb syntax question) In Event.h, is the declaration of dummy class Event;, then the EventPQ typedef, and then the real class Event declaration appropriate? I'm obviously an inexperienced programmer with very spotty background--this isn't for homework. Would love suggestions and explanations. Please let me know if any part of this is confusing. Thanks.

• Unwanted character being added to string in C

  - by Church

  I have a program that gives you shipping addresses from an input file. However at the beginning of one of the strings, order.add_one, a number is being added to the beginning of the string, that number is equivalent to the variable "choice" every time. Why is it doing this? #include <stdio.h> #include <math.h> #include <string.h> //structure typedef struct {char cust_name[25]; char cust_id[3]; char add_one[30]; char add_two[30]; char bike; char risky; int number_ordered; char cust_information[500]; }ORDER; ORDER order; int main(void){ fflush(stdin); system ( "clear" ); //initialize variables float price; float m = 359.95; float s = 279.95; //while loop, runs until user declares they no longer wish to input orders while (1==1){ printf("Options: \nEnter Customer information manually : 1 \nSearch Customer by ID(input.txt reader) : 2 \n"); int option = 0; scanf(" %d", &option); if (option == 1){ //Print and scan statements printf("Enter Customer Information\n"); printf("Customer Name: "); scanf(" %[^\n]s", &order.cust_name); printf("\nEnter Address Line One: "); scanf(" %[^\n]s", &order.add_one); printf("\nEnter Addres Line Two: "); scanf(" %[^\n]s", &order.add_two); printf("\nHow Many Bicycles Are Ordered: "); scanf(" %d", &order.number_ordered); printf("\nWhat Type Of Bike Is Ordered\n M Mountain Bike \n S Street Bike"); printf("\nChoose One (M or S): "); scanf(" %c", &order.bike); printf("\nIs The Customer Risky (Y/N): "); scanf(" %c", &order.risky); system ( "clear" ); } if (option == 2){ FILE *fpt; fpt = fopen("input.txt", "r"); if (fpt==NULL){ printf("Text file did not open\n"); return 1; } printf("Enter Customer ID: "); scanf("%s", &order.cust_id); char choice; choice = order.cust_id[0]; char x[3]; int w, u, y, z; char a[10], b[10], c[10], d[10], e[20], f[10], g[10], i[1], j[1]; int h; printf("%s value of c", c); if (choice >='1'){ while ((w = fgetc(fpt)) != '\n' ){ } } if (choice >='2'){ while ((u = fgetc(fpt)) != '\n' ){ } } if (choice >='3'){ while ((y = fgetc(fpt)) != '\n' ){ } } if (choice >= '4'){ while ((z = fgetc(fpt)) != '\n' ){ } } printf("\n"); fscanf(fpt, "%s", x); fscanf(fpt, "%s", a); printf("%s", a); strcat(order.cust_name, a); fscanf(fpt, " %s", b); printf(" %s", b); strcat(order.cust_name, " "); strcat(order.cust_name, b); fscanf(fpt, "%s", c); printf(" %s", c); strcat(order.add_one, "\0"); strcat(order.add_one, c); fscanf(fpt, "%s", d); printf(" %s", d); strcat(order.add_one, " "); strcat(order.add_one, d); fscanf(fpt, "%s", e); printf(" %s", e); strcat(order.add_two, e); fscanf(fpt, "%s", f); printf(" %s", f); strcat(order.add_two, " "); strcat(order.add_two, f); fscanf(fpt, "%s", g); printf(" %s", g); strcat(order.add_two, " "); strcat(order.add_two, g); strcat(order.add_two, "\0"); fscanf(fpt, "%d", &h); printf(" %d", h); order.number_ordered = h; fscanf(fpt, "%s", i); printf(" %s", i); order.bike = i[0]; fscanf(fpt, "%s", j); printf(" %s", j); order.risky = j[0]; fclose(fpt); printf("%s %s %s %d %c %c", order.cust_name, order.add_one, order.add_two, order.number_ordered, order.bike, order.risky); }

• Multi-threading does not work correctly using std::thread (C++ 11)

  - by user1364743

  I coded a small c++ program to try to understand how multi-threading works using std::thread. Here's the step of my program execution : Initialization of a 5x5 matrix of integers with a unique value '42' contained in the class 'Toto' (initialized in the main). I print the initialized 5x5 matrix. Declaration of std::vector of 5 threads. I attach all threads respectively with their task (threadTask method). Each thread will manipulate a std::vector<int> instance. I join all threads. I print the new state of my 5x5 matrix. Here's the output : 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 It should be : 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 42 0 0 0 0 0 1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 4 4 4 4 4 Here's the code sample : #include <iostream> #include <vector> #include <thread> class Toto { public: /* ** Initialize a 5x5 matrix with the 42 value. */ void initData(void) { for (int y = 0; y < 5; y++) { std::vector<int> vec; for (int x = 0; x < 5; x++) { vec.push_back(42); } this->m_data.push_back(vec); } } /* ** Display the whole matrix. */ void printData(void) const { for (int y = 0; y < 5; y++) { for (int x = 0; x < 5; x++) { printf("%d ", this->m_data[y][x]); } printf("\n"); } printf("\n"); } /* ** Function attached to the thread (thread task). ** Replace the original '42' value by another one. */ void threadTask(std::vector<int> &list, int value) { for (int x = 0; x < 5; x++) { list[x] = value; } } /* ** Return the m_data instance propertie. */ std::vector<std::vector<int> > &getData(void) { return (this->m_data); } private: std::vector<std::vector<int> > m_data; }; int main(void) { Toto toto; toto.initData(); toto.printData(); //Display the original 5x5 matrix (first display). std::vector<std::thread> threadList(5); //Initialization of vector of 5 threads. for (int i = 0; i < 5; i++) { //Threads initializationss std::vector<int> vec = toto.getData()[i]; //Get each sub-vectors. threadList.at(i) = std::thread(&Toto::threadTask, toto, vec, i); //Each thread will be attached to a specific vector. } for (int j = 0; j < 5; j++) { threadList.at(j).join(); } toto.printData(); //Second display. getchar(); return (0); } However, in the method threadTask, if I print the variable list[x], the output is correct. I think I can't print the correct data in the main because the printData() call is in the main thread and the display in the threadTask function is correct because the method is executed in its own thread (not the main one). It's strange, it means that all threads created in a parent processes can't modified the data in this parent processes ? I think I forget something in my code. I'm really lost. Does anyone can help me, please ? Thank a lot in advance for your help.

• OpenGL, draw two polygons in the same time (by mouse clicks)

  - by YoungSalafi

  im trying to draw 2 polygons at the same time depending on user input from the opengl screen... so i made 2 arrays which each one of them will carry the vertices of each polygon ... i think my logic is right but the program still prints only polygon and delete the old polygon if you draw a polygon again . and its acting weird too please check the code yourself here it is : P.S dont mind the delete function right now.. i know it missing something. #include <windows.h> #include <gl/gl.h> #include <gl/glut.h> void Draw(); void Set_Transformations(); void Initialize(int argc, char *argv[]); void OnKeyPress(unsigned char key, int x, int y); void DeleteVer(); void MouseClick(int bin, int state , int x , int y); void GetOGLPos(int x, int y,float* arrY,float* arrX); void DrawPolygon(float* arrX,float* arrY); float xPos[20]; float yPos[20]; float xPos2[20]; float yPos2[20]; float fx = 0,fy = 0; float size = 10; int count = 0; bool done = false; bool flag = true; void Initialize(int argc, char *argv[]) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_RGBA); glutInitWindowPosition(100, 100); glutInitWindowSize(600, 600); glutCreateWindow("OpenGL Lab1"); Set_Transformations(); glutDisplayFunc(Draw); glutMouseFunc(MouseClick); glutKeyboardFunc(OnKeyPress); glutMainLoop(); } void Set_Transformations() { glClearColor(1, 1, 1, 1); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluOrtho2D(-200, 200, -200, 200); } void OnKeyPress(unsigned char key, int x, int y) { if (key == 27) exit(0); switch(key) { case 13: //enter key it will draw done = true; glutPostRedisplay(); flag=!flag; // this flag to switch to the other array that the vertices will be stored in, in order to draw the second polygon break; } } void MouseClick(int button, int state , int x , int y) { switch (button) { case GLUT_RIGHT_BUTTON: if (state == GLUT_DOWN) { if (count>0) { DeleteVer(); //dont mind this right now } } break; case GLUT_LEFT_BUTTON: if (state == GLUT_DOWN) { if(count<20) { if(flag =true){ // drawing first polygon GetOGLPos(x, y,xPos,yPos);} if (flag=false) //drawing second polygon after Enter is pressed GetOGLPos(x, y,xPos2,yPos2); } } break; } } void GetOGLPos(int x, int y,float* arrY,float* arrX) //getting the vertices from the user { GLint viewport[4]; GLdouble modelview[16]; GLdouble projection[16]; GLfloat winX, winY, winZ; GLdouble posX, posY, posZ; glGetDoublev( GL_MODELVIEW_MATRIX, modelview ); glGetDoublev( GL_PROJECTION_MATRIX, projection ); glGetIntegerv( GL_VIEWPORT, viewport ); winX = (float)x; winY = (float)viewport[3] - (float)y; glReadPixels( x, int(winY), 1, 1, GL_DEPTH_COMPONENT, GL_FLOAT, &winZ ); gluUnProject( winX, winY, winZ, modelview, projection, viewport, &posX, &posY, &posZ); arrX[count] = posX; arrY[count] = posY; count++; glPointSize( 6.0 ); glBegin(GL_POINTS); glVertex2f(posX,posY); glEnd(); glFlush(); } void DeleteVer(){ //dont mind this glColor3f ( 1, 1, 1); glBegin(GL_POINTS); glVertex2f(xPos[count-1],yPos[count-1]); glEnd(); glFlush(); xPos[count] = NULL; yPos[count] = NULL; count--; glColor3f ( 0, 0, 0); } void DrawPolygon(float* arrX,float* arrY) { int n=0; glColor3f ( 0, 0, 0); glBegin(GL_POLYGON); while(n<count) { glVertex2f(arrX[n],arrY[n]); n++; } count=0; glEnd(); glFlush(); } void Draw() //main drawing func { glClear(GL_COLOR_BUFFER_BIT); glColor3f(0, 0, 0); if(done) { DrawPolygon(xPos,yPos); DrawPolygon(xPos2,yPos2); } glFlush(); } int main(int argc, char *argv[]) { Initialize(argc, argv); return 0; }

• Unable to set up SSL support for Apache 2 on Debian

  - by Francesco

  I am trying to set up ssl support for Apache 2 on Debian. Versions are: Debian GNU/Linux 6.0 apache2 2.2.16-6+squeeze1 I followed a lot of how-tos for days but I couldn't make it work. Here are my steps and configuration files (ServerName and DocumentRoot are changed for privacy, in case tell me): # mkdir /etc/apache2/ssl # openssl req $@ -new -x509 -days 365 -nodes -out /etc/apache2/apache.pem -keyout /etc/apache2/apache.pem at this point I've a doubt about permissions on apache.pem, at this step they are -rw-r--r-- 1 root root Maybe it has to belong to www-data? Then I enable ssl-mod with # a2enmod ssl # /etc/init.d/apache2 restart I modify /etc/apache2/sites-available/default-ssl in this way (I put port 8080 because I need port 443 for another purpose): <VirtualHost *:8080> SSLEngine on SSLCertificateFile /etc/apache2/ssl/apache.pem SSLCertificateKeyFile /etc/apache2/ssl/apache.pem ServerAdmin webmaster@localhost DocumentRoot /var/www <Directory /> Options Indexes FollowSymLinks AllowOverride All </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

My /etc/apache2/ports.conf is the following: # If you just change the port or add more ports here, you will likely also # have to change the VirtualHost statement in # /etc/apache2/sites-enabled/000-default # This is also true if you have upgraded from before 2.2.9-3 (i.e. from # Debian etch).

• Remote access to server via service control panel for non-admin user in Windows 2008

  - by owenevans00

  I'm trying to configure my Windows 2008 servers so that my developers can view their status without needing to log on to the box or be an admin. Unfortunately, the permissions set in Windows 2008 for remote non-admin users don't include the ability to enumerate or otherwise query services. This causes anything that contacts the SCM on the far end to fail (Win32_Service, sc.exe, services.msc etc). How do I set up permissions so that they can at least list the services and see if they are running?

• Binary Log Format in MySQL

  - by amritansu

  Reference manual for MySQL 5.6 states that " Some changes, however, still use the statement-based format. Examples include all DDL (data definition language) statements such as CREATE TABLE, ALTER TABLE, or DROP TABLE. " Does this statement means that even if we have ROW format for binary logs all DDLs will be logged in binary log as statement based? How does this affect replication? Kindly help me to understand this.
