  • Where to download unix command?

    - by person
    I tried to run mvdir earlier and it said command not found. I then ran a search for it and still not found. Is there a place I can download the script for the command, and is there any information I should know post-download to get it to work?

  • reorder XML elements or set an explicit template with XSLT

    - by Sash
    I tried the solution in my previous question (flattening XML to load via SSIS package), however this isn't working. I now know what I need to do, however I need some guidance on how to do it. So say I have the following XML structure: <person id="1"> <name>John</name> <surname>Smith</surname> <age>25</age> <comment> <comment_id>1</comment_id> <comment_text>Hello</comment_text> </comment> <comment> <comment_id>2</comment_id> <comment_text>Hello again!</comment_text> </comment> <somethingelse> <id>1</id> </somethingelse> <comment> <comment_id>3</comment_id> <comment_text>Third Item</comment_text> </comment> </person> <person id="2"> <name>John</name> <surname>Smith</surname> <age>25</age> <somethingelse> <id>1</id> </somethingelse> </person> ... ... If I am to load this into a SSIS package, as an XML source, what I will essentially get is a table created for each element, as opposed to get a structured table output such as person table (name, surname, age) somethingelse table (id) comment table (comment_id, comment_text) What I end up getting is: person table (person_Id <-- internal SSIS id) name table surname table age table person_name table person_surname table person_comment_comment_id table etc... What I found was that if each element and all inner elements are not in the same format and consistency, i will get the above anomaly which makes it rather complex especially if I am dealing with 80 - 100+ columns. Unfortunately I have no way of modifying the system (Lotus Notes) that produces these reports, so I was wondering whether I may be able to explicitly have an XSLT template that will be able to align each person sub elements (and the sub collection elements such as comments ? Unless there is a quicker way to realign all inner elements. Seems that SSIS XML source requires a very consistent XML file in the sense of: if the name element is in position 1, then all subsequent name elements within person parent have to be in position 1. SSIS seems to pickup the inconsistencies if there are certain elements missing from one parent to another, however, if their ordering is not right (A, B, C)(A, B, C)(A,C,B), it will chuck a massive fuss! All help is appreciated! Thank you in advance.

  • making an array controller the target of a button

    - by ian
    I am working through a chapter of COCOA PROGRAMMING FOR MAC OS X (3RD EDITION) on NSArrayController and it tells me to: Control-Drag to make the array controller become the target of the Add New Employee button.

  • Open file without specifying exact location

    - by person
    Say I have a file in some obscure directory that I want to open and edit. I don't want to do something like this... vim ~/foo/bar/blah/doh/ugh.txt I'd rather be able to say find this file and open it. I know there are commands like locate and find to find a file or directory, but I'm not sure whether these can (or even should) be utilized in what I'm trying to do. Basically, what is the simplest way to open a file with a program w/o specifying its exact location? (In cases where there isn't another file with the same name in the entire system, and cases where there are multiple).

  • Specific apache + mysql settings for a light-weight site

    - by Good Person
    I have a small website with a Joomla and a Moodle set up. It seems that both of these are very slow. The server (CentOS release 5.5 (Final)) is a virtual dedicated server with about 2GB of ram. I don't expect to ever get more than 10-15 people on at the same time (and if that is high) What settings could I change in either apache, mysql, or even the OS to increase the performance of my site? I'm not concerned about running out of resources if I get too many visitors. If you need more specific data leave a comment and I'll edit the question.

  • Changes to data inside class not being shown when accessed from outside class.

    - by Hypatia
    I have two classes, Car and Person. Car has as one of its members an instance of Person, driver. I want to move a car, while keeping track of its location, and also move the driver inside the car and get its location. However, while this works from inside the class (I have printed out the values as they are calculated), when I try to access the data from main, there's nothing there. I.e. the array position[] ends up empty. I am wondering if there is something wrong with the way I have set up the classes -- could it be a problem of the scope of the object? I have tried simplifying the code so that I only give what is necessary. Hopefully that covers everything that you would need to see. The constructer Car() fills the offset array of driver with nonzero values. class Car{ public: Container(float=0,float=0,float=0); ~Container(); void move(float); void getPosition(float[]); void getDriverPosition(float[]); private: float position[3]; Person driver; float heading; float velocity; }; class Person{ public: Person(float=0,float=0,float=0); ~Person(); void setOffset(float=0,float=0,float=0); void setPosition(float=0,float=0,float=0); void getOffset(float[]); void getPosition(float[]); private: float position[3]; float offset[3]; }; Some of the functions: void Car::move(float time){ float distance = velocity*time; location[0] += distance*cos(PI/2 - heading); location[1] += distance*sin(PI/2 - heading); float driverLocation [3]; float offset[3]; driver->getOffset(offset); for (int i = 0; i < 3; i++){ driverLocation[i] = offset[i] + location[i]; } } void Car::getDriverPosition(float p[]){ driver.getPosition(p); } void Person::getPosition(float p[]){ for (int i = 0; i < 3; i++){ p[i] = position[i]; } } void Person::getOffset(float o[]){ for (int i = 0; i < 3; i++){ o[i] = offset[i]; } } In Main: Car * car = new Car(); car->move(); float p[3]; car->getDriverPosition(p); When I print driverLocation[] inside the move() function, I have actual nonzero values. When I print p[] inside main, all I get are zeros.

  • how to move the camera behind a model with the same angle? in XNA

    I meet are having difficulty in moving my camera behind an object in a 3D world. I would create two view mode. 1: for fps (first person). 2nd: external view behind the character (second person). I searched the net some example but it does not work in my project. Here is my code used to change view if F2 is pressed //Camera double X1 = this.camera.PositionX; double X2 = this.player.Position.X; double Z1 = this.camera.PositionZ; double Z2 = this.player.Position.Z; //Verify that the user must not let the press F2 if (!this.camera.IsF2TurnedInBoucle) { // If the view mode is the second person if (this.camera.ViewCamera_type == CameraSimples.ChangeView.SecondPerson) { this.camera.ViewCamera_type = CameraSimples.ChangeView.firstPerson; //Calcul position - ??

  • Xna GS 4 Animation Sample bone transforms not copying correctly

    - by annonymously
    I have a person model that is animated and a suitcase model that is not. The person can pick up the suitcase and it should move to the location of the hand bone of the person model. Unfortunately the suitcase doesn't follow the animation correctly. it moves with the hand's animation but its position is under the ground and way too far to the right. I haven't scaled any of the models myself. Thank you. The source code (forgive the rough prototype code): Matrix[] tran = new Matrix[man.model.Bones.Count];// The absolute transforms from the animation player man.model.CopyAbsoluteBoneTransformsTo(tran); Vector3 suitcasePos, suitcaseScale, tempSuitcasePos = new Vector3();// Place holders for the Matrix Decompose Quaternion suitcaseRot = new Quaternion(); // The transformation of the right hand bone is decomposed tran[man.model.Bones["HPF_RightHand"].Index].Decompose(out suitcaseScale, out suitcaseRot, out tempSuitcasePos); suitcasePos = new Vector3(); suitcasePos.X = tempSuitcasePos.Z;// The axes are inverted for some reason suitcasePos.Y = -tempSuitcasePos.Y; suitcasePos.Z = -tempSuitcasePos.X; suitcase.Position = man.Position + suitcasePos;// The actual Suitcase properties suitcase.Rotation = man.Rotation + new Vector3(suitcaseRot.X, suitcaseRot.Y, suitcaseRot.Z); I am also copying the bone transforms from the animation player in the Person class like so: // The transformations from the AnimationPlayer Matrix[] skinTrans = new Matrix[model.Bones.Count]; skinTrans = player.GetBoneTransforms(); // copy each transformation to its corresponding bone for (int i = 0; i < skinTrans.Length; i++) { model.Bones[i].Transform = skinTrans[i]; }

  • What would you do if you were asked to recommend on someone you are not professionally satisfied with?

    - by Hila
    Where I live, everyone in the IT business knows just about everyone else. This is why it is quite common here to get a phone call from a recruiter asking for your professional opinion regarding people you've been working with in the past, or to be asked by a friend for a recommendation. This is all nice and well until you are asked to recommend on someone you weren't quite satisfied with professionally. There are several problems I can think about: Recommending on unskilled people is generally inadvisable. It is unprofessional and hurts your reputation. Giving this person a bad recommendation will probably hurt his chances of getting the job, and refusing to recommend on someone is just as bad as giving a bad recommendation. It may be that the new employer will be happy with this person's skills, is it fair to deny this guy of the chance to start a new page and prove himself in a new place? Many times you really like this person and are very uncomfortable with the idea of giving him a bad recommendation or refusing his request to recommend on him. What would you do in each of this cases: If this person asked you to recommend on him personally If you got a phone call from a recruiter asking for your opinion on him Thanks!

  • Facebook contest policy no-no?

    - by Fred
    I would like to post a link on a Facebook page where it will exit Facebook entirely and go to a client's website, where people will be on a page (client's) where they can enter their e-mail address to be entered in a temporary database file with rules and disclosures etc., for a draw once the number of entries reaches 100 for instance. Once the number of entries reaches 100, a random winner is picked and notified via E-mail. The functionality is as follows: A link is place on a Facebook page leading to an external page The page is a form to merely enter their email address for a contest The email is placed in a temporary file An automatic E-mail is sent to the address used for confirmation using SHAH-256 hash The person receives the Email saying something to the affect "Please confirm your Email address etc. - If you did not authorize this, simply ignore this message and no further action will be taken". If the person clicks on the confirmation link, the Email is then stored in the database and the person is again notified saying "Thank you for signing up etc." Once others do the same process and the database reaches a certain number, the form is no longer accessible and automatically picks a random Email. Once picked, an Email is automatically sent to the winner stating the instructions, and notifying me also. Once that person clicks yet another confirmation link, the database is then automatically deleted. I have built this myself and have no intentions of breaking any rules, nor jeopardize the work/time/energy I have put into this project. Is this allowed?

  • Msys cd .. command takes me to home directory instead of parent

    - by Adrian
    I'm using Msys on Windows 7 with what I believe to be a Bash shell. I want to navigate the following directory structure: Drive (M:) +--- Coding +--- CPP +--- projects +--- other_folder_1 +--- other_folder_2 My fstab file contains the following line: M:/Coding/CPP/projects/ /home/Adrian/ ... which makes the projects folder my starting directory when opening the shell. Unfortunately when I try to cd .. out of projects, I end up in /home instead of CPP. I imagine this might be related to what I did in the fstab file. Is there any way for me to retain the projects folder as my starting directory while being able to cd into its parent directories?

  • operator overloading of stream extraction operator in C++ help

    - by Crystal
    I'm having some trouble overloading my stream extraction operator in C++ for a hw assignment. I'm not really sure why I am getting these compile errors since I thought I was doing it right... Here is my code: Complex.h #ifndef COMPLEX_H #define COMPLEX_H class Complex { //friend ostream &operator<<(ostream &output, const Complex &complexObj) const; public: Complex(double = 0.0, double = 0.0); // constructor Complex operator+(const Complex &) const; // addition Complex operator-(const Complex &) const; // subtraction void print() const; // output private: double real; // real part double imaginary; // imaginary part }; #endif Complex.cpp #include <iostream> #include "Complex.h" using namespace std; // Constructor Complex::Complex(double realPart, double imaginaryPart) : real(realPart), imaginary(imaginaryPart) { } // addition operator Complex Complex::operator+(const Complex &operand2) const { return Complex(real + operand2.real, imaginary + operand2.imaginary); } // subtraction operator Complex Complex::operator-(const Complex &operand2) const { return Complex(real - operand2.real, imaginary - operand2.imaginary); } // Overload << operator ostream &Complex::operator<<(ostream &output, const Complex &complexObj) const { cout << '(' << complexObj.real << ", " << complexObj.imaginary << ')'; return output; // returning output allows chaining } // display a Complex object in the form: (a, b) void Complex::print() const { cout << '(' << real << ", " << imaginary << ')'; } main.cpp #include <iostream> #include "Complex.h" using namespace std; int main() { Complex x; Complex y(4.3, 8.2); Complex z(3.3, 1.1); cout << "x: "; x.print(); cout << "\ny: "; y.print(); cout << "\nz: "; z.print(); x = y + z; cout << "\n\nx = y + z: " << endl; x.print(); cout << " = "; y.print(); cout << " + "; z.print(); x = y - z; cout << "\n\nx = y - z: " << endl; x.print(); cout << " = "; y.print(); cout << " - "; z.print(); cout << endl; } Compile erros: complex.cpp(23) : error C2039: '<<' : is not a member of 'Complex' complex.h(5) : see declaration of 'Complex' complex.cpp(24) : error C2270: '<<' : modifiers not allowed on nonmember functions complex.cpp(25) : error C2248: 'Complex::real' : cannot access private member declared in class 'Complex' complex.h(13) : see declaration of 'Complex::real' complex.h(5) : see declaration of 'Complex' complex.cpp(25) : error C2248: 'Complex::imaginary' : cannot access private member declared in class 'Complex' complex.h(14) : see declaration of 'Complex::imaginary' complex.h(5) : see declaration of 'Complex' Thanks!

Any help will be greatly appreciated.

  • steam won't open after install

  • Ways to organize interface and implementation in C++

    - by Felix Dombek
    I've seen that there are several different paradigms in C++ concerning what goes into the header file and what to the cpp file. AFAIK, most people, especially those from a C background, do: foo.h class foo { private: int mem; int bar(); public: foo(); foo(const foo&); foo& operator=(foo); ~foo(); } foo.cpp #include foo.h foo::bar() { return mem; } foo::foo() { mem = 42; } foo::foo(const foo& f) { mem = f.mem; } foo::operator=(foo f) { mem = f.mem; } foo::~foo() {} int main(int argc, char *argv[]) { foo f; } However, my lecturers usually teach C++ to beginners like this: foo.h class foo { private: int mem; int bar() { return mem; } public: foo() { mem = 42; } foo(const foo& f) { mem = f.mem; } foo& operator=(foo f) { mem = f.mem; } ~foo() {} } foo.cpp #include foo.h int main(int argc, char* argv[]) { foo f; } // other global helper functions, DLL exports, and whatnot Originally coming from Java, I have also always stuck to this second way for several reasons, such as that I only have to change something in one place if the interface or method names change, and that I like the different indentation of things in classes when I look at their implementation, and that I find names more readable as foo compared to foo::foo. I want to collect pro's and con's for either way. Maybe there are even still other ways? One disadvantage of my way is of course the need for occasional forward declarations.

  • Recent update killed unity 3d launcher

    - by Steve
    I am scratching my head on this one, a lot of things are still new to me. I updated 126 packages just now through the update manager, and upon reboot everything works fine except the unity launcher. It's just a dark space. The dash still works, as does the top panel and docky. When I try: unity --replace I end up with this and then an indefinite hang: (compiz:3689): GConf-CRITICAL **: gconf_client_add_dir: assertion `gconf_valid_key (dirname, NULL)' failed WARN 2012-09-23 02:18:29 unity.favorites FavoriteStoreGSettings.cpp:139 Unable to load GDesktopAppInfo for 'ubiquity-gtkui.desktop' WARN 2012-09-23 02:18:30 unity.favorites FavoriteStoreGSettings.cpp:139 Unable to load GDesktopAppInfo for 'ubuntuone-installer.desktop' ERROR 2012-09-23 02:18:30 unity.launcher.trashlaunchericon TrashLauncherIcon.cpp:62 Could not create file monitor for trash uri: Operation not supported Initializing unityshell options...done WARN 2012-09-23 02:18:31 unity.libindicator <unknown>:0 Desktop file '/usr/share/applications/libreoffice-writer.desktop' is using a deprecated format for its actions that will be dropped soon.
