• Generating CMakeLists.txt

  - by vanna

  I got a bunch of C++ sources files and headers. They may use external libraries such as Boost e.g. I am interested in the process of building binaries for Windows and *nix. Makefiles (*nix) and .vcproj (Windows) call compilers with some specifications such as the order of compilation, compilation options and stuff. CMakeLists.txt can be used by CMake to build either makefiles or .vcproj and use very helpful commands such as recursive search of files, automatic linkage with known libraries, installers, variables that can be used in source files... Is there any existing tool that would generate a CMakeLists.txt from specified options ? Options could be like : scan this folder and make a library out of it, then scan this other folder and make an executable and automatically link both with Boost as well along with a user friendly installer with generated INSTALL.txt and README.txt. Something very powerful like that.

• Would it be possible to make an android app like this?

  - by ThisBetterWork

  I'm fairly new to android development and I'm not sure if the functionality I have in mind for my next project is actually feasible. I wanted to make a simple study guide app...when a user is browsing the web on their phone and they come across information they want to save to their study guide they would be able to highlight the sentence,long-click the highlighted text, and see an option to add it to their study guide(a pop-up list would appear). there would be more functionality than just this, for instance with-in the app you could create different study guide topics (biology,math, English..ect). But in general is it possible to have an app that is accessible by long-clicking when your browsing the web (as opposed to opening the App manually in order to use it.) -- If not, could I make it so you can open a browser within the app to do what I've described? This is going to be a school project so I don't care if it's totally original, I just want to make something simple and practical for practice. -- Thanks in advanced to anyone who helps!! :D

• Possible to stop Adobe DreamWeaver from rewriting 'onclick' to 'onClick'? [closed]

  - by DA01

  I've been giving my dev team grief by checking in HTML edited in DW. It turns out that DW has silently been rewriting all instances of 'onclick' to 'onClick' completely breaking the application in Webkit on us. I've done some digging on Google and this appears to be a bug that goes back to at least 2004. Supposedly it has nothing to do with your code re-writing settings and what triggers it is opening any document that does not contain a Doctype. Few of ours do, given that we're maintaining a framework that's using all sorts of include and dependency files. In all my Googling, I haven't found a fix, though. Has anyone come across one short of swearing off Adobe products forever?* something, btw, that I'm perfectly fine doing...it's just that given the insane IT lockdown on our work machines, we have very few software choices. For now, It's Notepad++ for me.

• Using a texture as an integer array (OpenGL 3.3, shader version 3.3)

  - by Cubic

  I'm trying to have something like an integer array uniform for my fragment shader (I only need read access). Since it's a fairly large chunk of data (not so large that uploading it in every frame would be impossible, but enough to make me want to rather not do it). Essentially I want to just pass it a uniform telling the shader where this "array" is. I believe I can use a 1D texture for this, but I don't know how (actually, I don't know how to do many things because I just can't seem to find a reference for GLSL 3.3, I only ever find references for the C API). This sounds like a rather basic question and I'm sure it's been answered already somewhere, but I keep searching and can't quite find what I'm looking for.

• How should dependencies be managed across a modular application?

  - by bear

  Let's say that we have a structure like this: Application -- Modules --Module1 -- Controller -- PublicHelper --Module2 -- Controller -- PublicHelper Whereby a module's Public Helper can provide helper functions. In nearly every module helper, the helper needs to access another module's public helper methods. Let's say for instance, in a PHP application: Module1 provides functionality to create a sale, and as part of the class Module1PublicHelper extends AbstractModuleHelper { public function createSale($customerId, $param, $param) { $userPublicHelper = // grab an instance of the user public helper $currentUser = $userPublicHelper->getCurrentUser(); } } class Module2PublicHelper extends AbstractModuleHelper { public function getCurrentUser() { //do something return $user; } } In this situation, the method needs to obtain an instance, either new or whatever of the user public helper. Given that all of Module Public Helper classes are instantiated with a minimum set of constructor params, e.g. EntityManager, what would be the best way to get a copy of it? Obviously, we can't really inject the user public helper class into the class containing createSale One solution would be to use a service locator or registry, however, testing the application isn't exactly easy.

• Is there a single book that covers the breadth of computer science fundamentals? [closed]

  - by superFoo

  When I did my undergraduate studies in elecrical engineering, there was this book called "Basic Electricity" by Van Valkenburgh. If you read that book cover to cover, your fundamentals in electrical engineering would be bulletproof. I would recommend it all my juniors and I absolutely loved it. Is there such a book in the field of computer science? I am not so concerned about the algorithms. I am looking more into something that tells me how does everything work beneath the covers. TCPIP, memory management, DNS, routing, SSL, buffer, queuing etc.

• Found a better solution to a problem at work - should I deter from posting the code snippet online?

  - by Calmarius

  I think most of us, programmers, used Stack Overflow to solve every day problems: looked for an efficient algorithm to do something. Now imagine a situation: you have a problem to solve. Googled a bit, found a StackOverflow question but you are not really satisfied with the answers so far. So you have to do your own research: you need to do it because you want it in the company's app. Eventually after some hours you have found the better solution. You're happy, you added it to the company's code base, then you want to submit your answer with a code snippet (just several lines) to the question you've found before to help others too. But wait: the company's software is closed source, and you worked on it on the clock. So does this mean I shouldn't post the answer neither at work nor at home to that question in the rest of my life, because I solved it at work, and the company owns that piece of code?

• Cannot see user desktop (Applications, Places, System...) when I log in

  - by Jesi

  I am very new to Ubuntu. I recently got a new laptop running Windows 7. I am using Virtual Box and just installed the Ubuntu 12.10 ISO as a new Virtual Machine within Virtual Box. Everything seemed to install just fine and I even added the Guest Additions under Devices. The problem is that I cannot see the menus and my login information. The virtual machine says it is running; however, I do not have the Applications, Places, System, etc. tray to select from. Is there something I am supposed to do after logging in to get this? I entered my password and everything seemed fine, I just don't have those drop-down menus available...

• multiple languages same pages shall I change the page URL path as well?

  - by Athanatos

  We own multiple country code top-level domains for our website e.g DE, UK ,FR. When someone visits for one of those domains they redirect to .com and the language automatically changes for the first time to the one from the originating domain. Also users can change the language from the .com website using a dropdown, however the page URI stays exactly the same e.g service.php. How will that be indexed in Google ? Will all the different language will be indexed or only the default lang (English) ? Is it recommended for SEO purposes to do something with the page URL (even using the htaccess maybe) so that I can also append to the title or page name the language ? e.g service.php?lang=fr

• Change gui port(8080) utorrent

  - by user87073

  I'm fresh on Ubuntu, still learning how to use it. Recently I've been trying to install utorrent, which I already was able to do so, but I need the port 8080 free to use run tomcat/glassfish and on port 80 php. Briefly, how can I change utorrent port from 8080 to another one? I've been trying to find a solution for this issue for about 3 days now, I saw some solutions, such as create a utserver.config, but I have no clue in how to use it or config it by terminal or on properties, that is something hardly explained by anyone. Any help will be appreciated :D.

• Dealing with Fanboys

  - by jozefg

  We've all probably met someone like this, that developer who just knows that his language is the one true language and won't shut up about it. How do you deal like someone like this? I don't want to offend anyone (especially since the fanboy in my workplace is the senior developer). But I want to be able to use my own choice of scripting language when I have to write a throwaway script that never makes it to the repository and no one else need know existed. Thoughts that I had to dealing with this: Laugh it off - "Haha yeah maybe language X is a bit easier, I guess I'm a masochist!" Go with it - I'd really prefer to avoid this as I can't afford the drop in productivity associated with picking up a new language. Hide my language - Become a closet programmer and hide my monitor whenever I'm scripting or automating something. What would you suggest for this situation?

• How can I restore /usr/share/fonts on 10.04?

  - by user207046

  I did something extremely stupid. I'm currently working on a 10.04 system (work-related), and since I was missing some fonts I decided to simply copy some over from my own, 12.10 system. I ran cp -R <12.10 root/usr/share/fonts/truetype/* /usr/share/fonts/truetype/ Immediately, terminal and window header fonts got completely messed up, although chromium still shows everything correctly, as does nautilus. How can I restore this directory? Is there anything else I have do afterwards? Thanks a bunch, Chris For shits and giggles, here's how it looks.

• Send some form info to a PHP page to be processed without going to that page? [closed]

  - by zuko

  Okay, so I'm not very familiar with php. I have a very simple form, just 2 text fields. All I want to do is, after validating with JavaScript, send these two string fields in an email to a pre-defined email address. I understand how JavaScript works on the client side; you can respond to user events, etc. And PHP is server-side. What I'm having trouble grasping and figuring out is how do I run PHP functions, etc when I want? I figured out how to use the 'action' attribute of the form to send the data via POST to another PHP page. But this simply opens that page. I don't want to open the page I just want to do some processing and send a message back to the page the user is still on. How do I go about something like that? Thanks.

• Where to find GUI code

  - by muffinz

  I've been rummaging through Unity's source code (Shell Interface) and I was a little curious about something; where in the code are you supposed to find positional code? I'll clarify a bit with some examples. How do you find in the code what tells the Launcher to sit on the left side of the screen? Where in the code does it tell the "Session" button on the panel (top) to sit at the very right of the screen? I guess my real question is how do I find this out for myself? I've looked through a big portion of the source code and can't find anything related to the actual position of these items, only their sub-items like text-align. Any guidance on this would be much appreciated.

• loadparm.c:4864, leaking memory?

  - by RandomOzzy

  I’m running Ubuntu 14.04 Server with a LAMP stack, Samba, and FTP, no GUI, just SSHing into the server and working on it. I’m having trouble searching down a solution to this issue, but as far as I can Google for it, it might have something to do with Samba. no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory?? The warning doesn't pop up at any kind of regular intervals or in response to the same or repeated actions. It pops up between things I’m doing - changing directories, editing files, copying stuff, and it often pops up when I first log in. Has anyone got experience fixing this issue?

• Is there a way of leveling/compressing the sound system-wide?

  - by JethroDawnfine

  As a Laptop user, I'm sure that a lot of people, even the ones using Netbooks would have already gone through this problem. Especially when listening to podcasts, and using it as an example, the sound might have loud moments and quiet moments, one person speaking loud and the other speaking very quiet in the same episode. Thereby, I always wanted the sound to be compressed system-wide, and I just noted the other day, that in Windows, some Realtek drivers already offer this function. We have already a pulseaudio plugin for equalization system-wide, and although it still has problems like not letting us change its values and listen the change in real time, or cracking the sound while changing pulse volume, I do love it and use it. Now I'm just missing something to keep the sound around 0db (or near the volume level you're using) as a leveler plugin for pulseaudio. Any suggestion?

• How to turn off power management for external hard drive (Seagate GoFlex)?

  - by RPG Master

  I bought this 2tb Segate GoFlex this last Black Friday and since then every 15 minutes or so the drive spins down, and then a little while later completely dismounts. Very annoying. From what I understand you could turn this off using the including Windows and Mac only software. This function and what controls it isn't proprietary, right? There has to be something that'll let me set it in Ubuntu... Anyone have any suggestions? Also, I formatted it to EXT4. Hope I didn't screw myself up. :/

• How do I do a game loop in c99?

  - by linitbuff

  I'm having trouble with how to structure a game using c99. I've seen a few tutorials on making a game loop, but they are all done with c++ and classes. My main problem seems to be moving data around between the functions without creating a mess, and what stuff to put in what header files etc. Do I just do something similar to the c++ loops, and create a class-like header with a structure containing all items needed by more than one of the functions, along with the prototypes of said functions, and include the header in each function's header file? Then, in the main function, instantiate the structure and pass a pointer to it to every function in the loop? Is this ok, or is there a better way to do it, and are there any good 'c' specific tutorials available? Cheers

• Running Visual Studio 2012 on a convertable windows 8 tablet? [closed]

  - by Tony

  I was unsure on where to post this question so I am posting here. I was wondering if any of you are using one of the new windows 8 convertible tablets to do web development on? If so what model are you using and how do you find the experience? I have a monster gaming laptop that I usually use to develop on but it is so large and is a real pain to move around with. I would like something that is extremely portable and would effectively let me develop anywhere.

• Will a standard CMS on a shared web hosting account work for this?

  - by user1185305

  I have two questions concerning CMS's that I need answered if possible: I need to create a site with a Database. This site will in due time have lots of traffic and many users if things go as planned. Is it better to have the CMS on a shared web hosting account or is it better to have a dedicated server for this? The site I want to create needs to be able to create groups where each group has its own admin. The admin of the group decides the content that each member can view/access. The information of one group can be shared to other groups as well. This means that only the information content is shared but not the group's member data. Should I use a single or multiple databases for this problem? Is this something that can be done using standard CMS systems out there. or should I try to build one myself?

• Application window as polygon texture?

  - by nekome

  Is there a way, or method, to have some application rendered as texture in 3D scene on some polygon, and also have full interactivity with it? I'm talking about Windows platform, and maybe OpenGL but I guess it doesn't matter is it OGL or DX. For example: I run Calculator using WINAPI functions (preferably hidden, not showing on desktop) and I want to render it inside 3D scene on some polygon but still be able to type or click buttons and have it respond. My idea to realize this is to have WINAPI take screenshot (or render it to memory if possible) of that Calculator and pass it to OpenGL as texture for each frame (I'm experimenting with SDL through pygame) and for mouse interactivity to use coordination translation and calculate where on application window it would act, and then use WINAPI functions such as SetCursorPos to set cursor ant others to simulate click or something else. I haven't found any tutorials with topic similar to this one. Am I on a right track? Is there better way to do this if possible at all?

• Second monitor stopped working

  - by Mark D

  After setting up 11.10 today, I seem to be having problems with my dual monitor set up. It worked without issues in Mint but today after I switched to 11.10 only one monitor seems to function. This seems a little odd to me. During setup both monitors functioned without issue, although they were mirroring each other both monitors but as soon as it booted into Unity my secondary monitor stopped working. I checked under settings-display and the second monitor doesn't seem to even be detected. On the off chance it had something to do with drivers, I upgraded the proprietary drivers to the latest version with zero success. If anyone has any ideas, I'd love to hear them.

• fault tolerant uploading tool

  - by andersonbd1

  I'm setting up a wordpress site for a friend who has some somewhat large audio files (150M)... He's on a bad connection and I'd guess it'll take him a while to upload those files with the normal wordpress way. I'm looking for a tool that I can install on the server that allows uploads and is also fault tolerant... for example if you loses his connection, or power, or whatever it'll pick up where it left off. I realize web technologies probably don't do that, but perhaps flash or something? Any ideas?
