• Backing up bind mounted folders

  - by NahsiN

  My layout is as follows. LVM Setup: /dev/VG/Documents, /dev/VG/Music, /dev/VG/Pictures, /dev/VG/Music, /dev/VG/Documents, etc.... Each of the LVMs is bind mounted to the corresponding folder name in /home/foo. For example, /home/foo/Documents bind mounted to /media/Documents (mount point of /dev/VG/Documents), etc. If I set up deja-dup to just back up my home folder, am I guaranteed that everything from my LVMs will be backed up properly? So let's say I take away my LVMs for some reason and choose to restore an earlier backup. My home folder will contain everything from the LVMs? All my docs, music, vids etc. My intuition tells me everything will be fine but it doesn't hurt to ask the the experts ;). Hope I have made myself clear. Thanks

• Avoiding coupling

  - by Seralize

  It is also true that a system may become so coupled, where each class is dependent on other classes that depend on other classes, that it is no longer possible to make a change in one place without having a ripple effect and having to make subsequent changes in many places.[1] This is why using an interface or an abstract class can be valuable in any object-oriented software project. Quote from Wikipedia Starting from scratch I'm starting from scratch with a project that I recently finished because I found the code to be too tightly coupled and hard to refactor, even when using MVC. I will be using MVC on my new project aswell but want to try and avoid the pitfalls this time, hopefully with your help. Project summary My issue is that I really wish to keep the Controller as clean as possible, but it seems like I can't do this. The basic idea of the program is that the user picks wordlists which is sent to the game engine. It will pick random words from the lists until there are none left. Problem at hand My main problem is that the game will have 'modes', and need to check the input in different ways through a method called checkWord(), but exactly where to put this and how to abstract it properly is a challenge to me. I'm new to design patterns, so not sure whether there exist any might fit my problem. My own attempt at abstraction Here is what I've gotten so far after hours of 'refactoring' the design plans, and I know it's long, but it's the best I could do to try and give you an overview (Note: As this is the sketch, anything is subject to change, all help and advice is very welcome. Also note the marked coupling points): Wordlist class Wordlist { // Basic CRUD etc. here! // Other sample methods: public function wordlistCount($user_id) {} // Returns count of how many wordlists a user has public function getAll($user_id) {} // Returns all wordlists of a user } Word class Word { // Basic CRUD etc. here! // Other sample methods: public function wordCount($wordlist_id) {} // Returns count of words in a wordlist public function getAll($wordlist_id) {} // Returns all words from a wordlist public function getWordInfo($word_id) {} // Returns information about a word } Wordpicker class Wordpicker { // The class needs to know which words and wordlists to exclude protected $_used_words = array(); protected $_used_wordlists = array(); // Wordlists to pick words from protected $_wordlists = array(); /* Public Methods */ public function setWordlists($wordlists = array()) {} public function setUsedWords($used_words = array()) {} public function setUsedWordlists($used_wordlists = array()) {} public function getRandomWord() {} // COUPLING POINT! Will most likely need to communicate with both the Wordlist and Word classes /* Protected Methods */ protected function _checkAvailableWordlists() {} // COUPLING POINT! Might need to check if wordlists are deleted etc. protected function _checkAvailableWords() {} // COUPLING POINT! Method needs to get all words in a wordlist from the Word class } Game class Game { protected $_session_id; // The ID of a game session which gets stored in the database along with game details protected $_game_info = array(); // Game instantiation public function __construct($user_id) { if (! $this->_session_id = $this->_gameExists($user_id)) { // New game } else { // Resume game } } // This is the method I tried to make flexible by using abstract classes etc. // Does it even belong in this class at all? public function checkWord($answer, $native_word, $translation) {} // This method checks the answer against the native word / translation word, depending on game mode public function getGameInfo() {} // Returns information about a game session, or creates it if it does not exist public function deleteSession($session_id) {} // Deletes a game session from the database // Methods dealing with game session information protected function _gameExists($user_id) {} protected function _getProgress($session_id) {} protected function _updateProgress($game_info = array()) {} } The Game /* CONTROLLER */ /* "Guess the word" page */ // User input $game_type = $_POST['game_type']; // Chosen with radio buttons etc. $wordlists = $_POST['wordlists']; // Chosen with checkboxes etc. // Starts a new game or resumes one from the database $game = new Game($_SESSION['user_id']); $game_info = $game->getGameInfo(); // Instantiates a new Wordpicker $wordpicker = new Wordpicker(); $wordpicker->setWordlists((isset($game_info['wordlists'])) ? $game_info['wordlists'] : $wordlists); $wordpicker->setUsedWordlists((isset($game_info['used_wordlists'])) ? $game_info['used_wordlists'] : NULL); $wordpicker->setUsedWords((isset($game_info['used_words'])) ? $game_info['used_words'] : NULL); // Fetches an available word if (! $word_id = $wordpicker->getRandomWord()) { // No more words left - game over! $game->deleteSession($game_info['id']); redirect(); } else { // Presents word details to the user $word = new Word(); $word_info = $word->getWordInfo($word_id); } The Bit to Finish /* CONTROLLER */ /* "Check the answer" page */ // ?????????????????? ( http://pastebin.com/cc6MtLTR ) Make sure you toggle the 'Layout Width' to the right for a better view. Thanks in advance. Questions To which extent should objects be loosely coupled? If object A needs info from object B, how is it supposed to get this without losing too much cohesion? As suggested in the comments, models should hold all business logic. However, as objects should be independent, where to glue them together? Should the model contain some sort of "index" or "client" area which connects the dots? Edit: So basically what I should do for a start is to make a new model which I can more easily call with oneliners such as $model->doAction(); // Lots of code in here which uses classes! How about the method for checking words? Should it be it's own object? I'm not sure where I should put it as it's pretty much part of the 'game'. But on another hand, I could just leave out the 'abstraction and OOPness' and make it a method of the 'client model' which will be encapsulated from the controller anyway. Very unsure about this.

• How to alter image pixels of a wild life bird?

  - by NoobScratcher

  Hello so I was hoping someone knew how to move or change color and position actual image pixels and could explain and show the code to do so. I know how to write pixels on a surface or screen-surface usigned int *ptr = static_cast <unsigned int *> (screen-pixels); int offset = y * (screen->pitch / sizeof(unsigned int)); ptr[offset + x] = color; But I don't know how to alter or manipulate a image pixel of a png image my thoughts on this was How do I get the values and locations of pixels and what do I have to write to make it happen? Then how do I actually change the values or locations of those gotten pixels and how do I make that happen? any ideas tip suggestions are also welcome! int main(int argc , char *argv[]) { SDL_Surface *Screen = SDL_SetVideoMode(640,480,32,SDL_SWSURFACE); SDL_Surface *Image; Image = IMG_Load("image.png"); bool done = false; SDL_Event event; while(!done) { SDL_FillRect(Screen,NULL,(0,0,0)); SDL_BlitSurface(Image,NULL,Screen,NULL); while(SDL_PollEvent(&event)) { switch(event.type) { case SDL_QUIT: return 0; break; } } SDL_Flip(Screen); } return 0; }

• iOS build machine setup: problem with certificates

  - by cbrulak

  some background: work with multiple team mates each work on our own MBP I'm setting a build machine that we can git push to in order to generate a build (aim to allow anyone to push to the build machine and then generate an archive, upload to testflight and send on its way) problem: getting my apple developer certificates on the build machine. I installed Lion, XCode, etc and I signed into my developer account through Xcode organizer, provisioning profiles download,etc. but beside each one it says: valid signing identity not found I also download my certificate from the developer.apple.com page, imported it into keychain, etc but no luck. Anyone else have a similar issue? Or maybe hints to fix? Thanks

• Question about a simple design problem

  - by Uri

  At work I stumbled uppon a method. It made a query, and returned a String based on the result of the query, such as de ID of a customer. If the query didn't return a single customer, it'd return a null. Otherwise, it'd return a String with the ID's of them. It looked like this: String error = getOwners(); if (error != null) { throw new Exception("Can't delete, the flat is owned by: " + error); } ... Ignoring the fact that getCustomers() returns a null when it should instead return an empty String, two things are happening here. It checks if the flat is owned by someone, and then returns them. I think a more readable logic would be to do this: if (isOwned) { throw new Exception("Can't delete, the flat is owned by: " + getOwners()); } ... The problem is that the first way does with one query what I do with two queries to the database. What would be a good solution involving good design and efficiency for this?

• Implementing a switch statement based on user input

  - by Dave Voyles

  I'm trying to delay the time it takes for the main menu screen to pop up after a user has won / lost a match. As it stands, the game immediately displays a message stating "you won / lost" and waits for 6 seconds before loading the menu screen. I would also like players to have the ability to press a key to advance to the menu screen immediately but thus far my switch statement doesn't seem to do the trick. I've included the switch statement, along with my (theoretical) inputs. What could I be doing wrong here? if (gamestate == GameStates.End) switch (input.IsMenuDown(ControllingPlayer)) { case true: ScreenManager.AddScreen(new MainMenuScreen(), null); // Draws the MainMenuScreen break; case false: if (screenLoadDelay > 0) { screenLoadDelay -= gameTime.ElapsedGameTime.TotalSeconds; } ScreenManager.AddScreen(new MainMenuScreen(), null); // Draws the MainMenuScreen break; } /// <summary> /// Checks for a "menu down" input action. /// The controllingPlayer parameter specifies which player to read /// input for. If this is null, it will accept input from any player. /// </summary> public bool IsMenuDown(PlayerIndex? controllingPlayer) { PlayerIndex playerIndex; return IsNewKeyPress(Keys.Down, controllingPlayer, out playerIndex) || IsNewButtonPress(Buttons.DPadDown, controllingPlayer, out playerIndex) || IsNewButtonPress(Buttons.LeftThumbstickDown, controllingPlayer, out playerIndex); }

• Algorithm to match timestamped events from two sources

  - by urza.cc

  I have two different physical devices (one is camera, one is other device) that observe the same scene and mark when a specified event occures. (record timestamp) So they each produce a serie of timestamps "when the event was observed". Theoretically the recorded timestamps should be very well aligned: Visualized ideal situation on two time lines "s" and "r" as recorded from the two devices: but more likely they will not be so nicely aligned and there might be missing events from timeline s or r: I am looking for algorithm to match events from "s" and "r" like this: So that the result will be something like: (s1,null); (s2,r1); (s3,null); (s4,r2); (s5,r3); (null,r4); (s6,r5); Or something similar. Maybe with some "confidence" rating. I have some ideas, but I feel that this might be probably a well known problem, that has some good known solutions, but I don't know the right terminology. I am a little bit out of my element here, this is not my primary area of programming.. Any helps, suggestions etc will be appreciated.

• Why does Unity in 2d mode employ scaling and the default othographic size the way it does?

  - by Neophyte

  I previously used SFML, XNA, Monogame, etc to create 2d games, where if I display a 100px sprite on the screen, it will take up 100px. If I use 128px tiles to create a background, the first tile will be at (0,0) while the second will be at (129,0). Unity on the other hand, has its own odd unit system, scaling on all transforms, pixel-to-units, othographic size, etc etc. So my question is two-fold, namely: Why does Unity have this system by default for 2d? Is it for mobile dev? Is there a big benefit I'm not seeing? How can I setup my environment, so that if I have a 128x128 sprite in Photoshop, it displays as a 128x128 sprite in Unity when I run my game? Note that I am targeting desktop exclusively.

• How to properly backup mediawiki database (mysql) without messing up the data?

  - by Toto

  I want to backup a mediawiki database stored in a MySQL server 5.1.36 using mysqldump. Most of the wiki articles are written in spanish and a don't want to mess up with it by creating the dump with the wrong character set. mysql> status -------------- ...

• how to really master a programming language

  - by cprogcr

  I know that learning a language, you can simply buy a book, follow the examples, and whenever possible try the exercises. But what I'm really looking is how to master the language once you've learned it. Now I know that experience is one major factor, but what about learning the internals of the language, what is the underlying structure, etc. There are articles out there saying read this book, read that book, make this game and that game. But to me this doesn't mean to master a language. I want to be able to read other people's code and understand it, no matter how hard that is. To understand when to use a function and when another, etc etc. The list could go on and on but I believe I've made the point. :) And finally, take whatever language as an example if needed, though best would be if C was taken as an example.

• Ububtu 13.04 Rename Computer

  - by Sourabh

  How can I rename my computer? Renaming it in /etc/hosts and /etc/hostname does something weird. Before renaming it, I am able to open these files via sublime using sudo subl /etc/hosts but when I rename my Computer (using nano) and open any of these files using subl, I get this message: No protocol specified (sublime_text:20071): Gtk-WARNING **: cannot open display: :0.0 So I guess renaming in the above files is not the only thing I have to do. PS: If I rename using sublime, after renaming one of the files, I get same message when I try to open other file

• Is there a way to change the root password while still logged in? I did something bad by accdient -_-

  - by Robert

  So I was trying to add my printer, and I wasn't able to make any changes due to the fact that cups was not accepting my root password. I was Googling some changes and trying to fix the problem when one of the commands CHANGED MY SUDO PASSWORD! Can someone please tell me which one of these is the culprit? I was trying to these commands: cat /etc/group | grep root cat /etc/group | grep myUserName usermod -a -G lpadmin myUserName sudo usermod -a -G lpadmin myUserName sudo gedit /etc/cups/cupsd.conf lppasswd -a myUserName lppasswd -a root sudo lppasswd -a myUserName I think it was this one, but I know which passwords I put in! There was nothing which I typed in besides my strong password or my easy temporary password. Unless I made a typo... please no. restart cups sudo password root This is so not cool, I was just trying to add a printer :'( Please help my stupidity!

• Who keeps removing that file?

  - by mgerdts

  Over the years, I've had many times when some file gets removed and there's no obvious culprit.  With dtrace, it is somewhat easy to figure out:  #! /usr/sbin/dtrace -wqs syscall::unlinkat:entry /cleanpath(copyinstr(arg1)) == "/dev/null"/ {         stop();         printf("%s[%d] stopped before removing /dev/null\n", execname, pid);         system("ptree %d; pstack %d", pid, pid); } That script will stop the process trying to remove /dev/null before it does it.  You can allow it to continue by restarting (unstopping?) the command with prun(1) or killing it with kill -9.  If you want the command to continue automatically after getting the ptree and pstack output, you can add "; prun %d" and another pid argument to the system() call.

• How can I have a Bluetooth Keyboard Auto-Connect at Startup?

  - by Grant

  I have a bluetooth keyboard for my HTPC. I pair it with my computer via bluetooth, and it works fine. However, when I turn off the keyboard or my computer, it has to connect again (which requires me entering a passcode on the computer and keyboard) when I turn them back on. I've looked through many forums and through that I have found that I'm missing some seemingly vital bluetooth files: /etc/default/bluetooth /etc/init.d/bluetooth /etc/bluetooth/hcid.conf In the instructions that I've found online so far, I must change certain lines in any of these files. I am unable to, since they do not exist. Am I missing a dependency or something? I've also tried installing Blueman but that didn't help at all. I'm running Ubuntu 10.10 (Maverick).

• Restricting access to sites

  - by Paul

  I'm having some problems configuring my local proxy server so that it would restrict access to certain websites. The proxy server I'm using is Squid; I edited its configuration file found in /etc/squid/squid.conf to include the following: acl wikipedia dstdomain .wikipedia.org http_access deny wikipedia I tried to redirect elinks to use Squid. According to Squid's config file, it listens to port 3128, so in /etc/elinks/elinks.conf I added the following: set protocol.http.proxy.host = "localhost:3128" I also restarted Squid with sudo /etc/init.d/squid restart, but I can still access the banned websites using Elinks. What did I do wrong?

• What is the best database design for managing historical information? [closed]

  - by Emmad Kareem

  Say you have a Person table with columns such as: ID, FirstName, LastName, BirthCountry, ...etc. And you want to keep track of changes on such a table. For example, the user may want to see previous names of a person or previous addresses, etc. The normalized way is to keep names in separate table, addresses in a separate table,...etc. and the main person table will contain only the information that you are not interested in monitoring changes for (such information will be updated in place). The problem I see here, aside form the coding hassle due to the extensive number of joins required in a real-life situation, is that I have never seen this type of design in any real application (maybe because most did not provide this feature!). So, is there a better way to design this? Thanks.

• Resource Acquisition is Initialization in C#

  - by codeWithoutFear

  Resource Acquisition Is Initialization (RAII) is a pattern I grew to love when working in C++.  It is perfectly suited for resource management such as matching all those pesky new's and delete's.  One of my goals was to limit the explicit deallocation statements I had to write.  Often these statements became victims of run-time control flow changes (i.e. exceptions, unhappy path) or development-time code refactoring. The beauty of RAII is realized by tying your resource creation (acquisition) to the construction (initialization) of a class instance.  Then bind the resource deallocation to the destruction of that instance.  That is well and good in a language with strong destructor semantics like C++, but languages like C# that run on garbage-collecting runtimes don't provide the same instance lifetime guarantees. Here is a class and sample that combines a few features of C# to provide an RAII-like solution: using System; namespace RAII { public class DisposableDelegate : IDisposable { private Action dispose; public DisposableDelegate(Action dispose) { if (dispose == null) { throw new ArgumentNullException("dispose"); } this.dispose = dispose; } public void Dispose() { if (this.dispose != null) { Action d = this.dispose; this.dispose = null; d(); } } } class Program { static void Main(string[] args) { Console.Out.WriteLine("Some resource allocated here."); using (new DisposableDelegate(() => Console.Out.WriteLine("Resource deallocated here."))) { Console.Out.WriteLine("Resource used here."); throw new InvalidOperationException("Test for resource leaks."); } } } } The output of this program is: Some resource allocated here. Resource used here. Unhandled Exception: System.InvalidOperationException: Test for resource leaks. at RAII.Program.Main(String[] args) in c:\Dev\RAII\RAII\Program.cs:line 40 Resource deallocated here. Code without fear! --Don

• Setting umask globally

  - by DevSolar

  I am using a private user group setup, i.e. a user foo's home directory is owned by foo:foo, not foo:users. For this to work, I need to set the umask to 002 globally. After a quick grep -RIi umask /etc/*, it seemed for a moment that modifying the UMASK entry in /etc/login.defs should do the trick. It does, too -- but only for console logins. If I log in to my desktop, and open a terminal there, I still get to see the default umask 022. Same goes for files created from apps started through the menu. Apparently, the display manager (or whatever X11 component responsible) does source some different setting than a console login does, and damned if I could tell which one it is. (I tried changing the setting in /etc/init.d/rc, and no, it did not help.) How / where do I set umask globally, so that the X11 desktop environment gets the memo as well?

• What "version naming convention" do you use?

  Are different version naming conventions suited to different projects? What do you use and why? Personally, I prefer a build number in hexadecimal (e.g 11BCF), this should be incremented very regularly. And then for customers a simple 3 digit version number, i.e. 1.1.3. 1.2.3 (11BCF) <- Build number, should correspond with a revision in source control ^ ^ ^ | | | | | +--- Minor bugs, spelling mistakes, etc. | +----- Minor features, major bug fixes, etc. +------- Major version, UX changes, file format changes, etc.

• XNA 4: RenderTarget2D textures getting transparent on fullscreen

  I'm generating a Texture2D object using RenderTarget2D as in the following code public static Texture2D GetTextTexture(string text, Vector2 position, SpriteFont font, Color foreColor, Color backColor, Texture2D background=null) { int width = (int)font.MeasureString(text).X; int height = (int)font.MeasureString(text).Y; GraphicsDevice device = Settings.game.GraphicsDevice; SpriteBatch spriteBatch = Settings.game.spriteBatch; RenderTarget2D renderTarget = new RenderTarget2D(device, width, height, false, SurfaceFormat.Color, DepthFormat.Depth24Stencil8, device.PresentationParameters.MultiSampleCount, RenderTargetUsage.DiscardContents); device.SetRenderTarget(renderTarget); device.Clear(backColor); spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.Opaque); if (background != null) spriteBatch.Draw(background, new Rectangle(0, 0, 70, 70), Color.White); spriteBatch.End(); spriteBatch.Begin(); spriteBatch.DrawString(font, text, position, foreColor, 0, new Vector2(0), 0.8f, SpriteEffects.None, 0); spriteBatch.End(); device.SetRenderTarget(null); ResetGraphicsDeviceSettings(); return (Texture2D)renderTarget; } It's working all fine. But when I ToggleFullScreen() (and vice-versa), the previous textures are getting transparent. However, the new textures after that are being generated correctly. What can be the reason for this?

• Should a new programmer nowadays start with C/C++ or OOP language? [closed]

  - by deviDave

  I've been a programmer for 15+ years. In my time, we all started with C or C++ and then moved to C# or Java. At that time it was a usual practice. Now, my brother wants to follow my steps and I am not sure what advice to give him. So, I am asking the community for an opinion. Should nowadays new programmer with zero programming knowledge start with functional languages (C, C++, etc.) or he should start directly with OOP languages (Java, C#, etc.)? The reply should be considered in the context of my brother's future assignments. He will mainly work on Java mobile applications as well as ASP.NET web apps. He will have to touch with desktop apps, low level programming, drivers, etc. This is the reason I am not sure if he should ever need to learn functional languages.
