  • How do I implement Unreal-like object serialization?

    - by MrWiggels
    Recently, I've been working on the core of my engine, and as I'm moving forward I find myself developing throwaway code to read files and simple data into the engine. This got me thinking about how I should implement a file management system. After a bit of googleing I came across the Unreal Package format, and boy does it look like the perfect one. I think it's good because the way how it allows you to separate different assets into different packages and allow something like a level to reference the different packages. I was just wondering, is this possible with C#? Because the built-in serialization API in .NET does not seem to support any form of this, only reading and writing to a single file.

  • How will wayland be delivered?

    - by Chris Woollard
    Mark just announched support for wayland in Ubuntu in future. I was just wondering the following (Hopefully Mark can answer). Obviously this is quite a significant piece of work. When will a version be available to test? Will it be available as a package(s) in the repository or will it be delivered as its own distribution e.g. wayBuntu? When do you expect it to take over as the default (e.g. 11.11)? Thanks Chris

  • What's the best platform for blogging about coding? [closed]

    - by timday
    I'm toying with starting an occasional blog for posting odd bits of coding related stuff (mainly C++, probably). Are there any platforms which can be recommended as providing exceptionally good support (e.g syntax highlighting) for posting snippets of code ? (Or any to avoid because posting mono-spaced font blocks of text is a pain). Outcome: I accepted Josh K's answer because what I actually ended up doing was realizing I was more interested in articles than a blog style, getting back into LaTeX (after almost 20 years away from it), using the "listings" package for code, and pushing the HTML/PDF results to my ISP's static-hosting pages. (HTML generated using tex4ht). Kudos to the answers mentioning Wordpress, Tumblr and Jekyll; I spent some time looking into all of them.

  • Truly useful UML diagrams

    - by eversor
    UML has a jungle of Diagrams. Profile Diagrams, Class Diagrams, Package Diagrams... However, (IMH-and-not-too-experienced-O) I quite see that doing each and every diagram is overkill. Therefore, which UML Diagrams are more suitable in a web context, more expecificly a blog (we want to build it from scratchs). I understand that just because I used UML Diagrams does not imply that our code would be great and brilliant... but, it certainly would be better than just unplanified code...

  • Where are Nagios 3 Config Files in Ubuntu 12.04?

    - by Aaron James
    I just installed Nagios3 via Synaptic. The package and it's dependencies all installed fine and I log in using a web browser, however I'd like to add hosts now and according to the official Nagios Documentation the config file should be in the /usr/local/nagios/* directory. When I go to /usr/local it's not there. I can't seem to find these config files anywhere. I'm not sure what I did wrong. I'm running Xubuntu 12.04 64-bit Any help at all would be greatly appreciated, Thank you!

  • Compiz and Clearlooks window border breaks active/inactive title bars

    - by jimbo1qaz
    When I turn on Compiz with the Compiz tray switcher and I use Clearlooks, Dust Sand, or possibly any title bar style that normally has window icons on right, some window title bars will not change. Instead, they stay selected or unselected randomly. Some windows, like Ubuntu Software Center and CCSM are unaffected. This problem only happens with GTK window manager. I am using the Malteworld compiz ppa for Emerald. The problem does not happen with plain Metacity, or a title bar style that normally has close button on right. Edit: It still happens with Emerald. Reinstalled with upgrade option (yeah, 11.04 to 11.04) and still same problem. So maybe faulty package?

  • ifconfig not showing all IPs bound to the machine

    I have configured multiple IP addresses on a ubuntu box, but when I run ifconfig it shows just one of them.

  • How To Upgrade Wine from 1.2 to 1.5 in Maverick 10.10

    - by Subhash
    I am using Maverick Meerkat (10.10). It has Wine 1.2. I followed the instructions at WinHQ for updating wine. In Synaptic Package Manager, the highest version I get now for upgrading is 1.3, not 1.5. How can I get upgrade to Wine 1.5? I do not want to upgrade the Ubuntu version. It seems that some of the supporting libraries such as lib6 are old. I would like to know how I can update them so as to make Wine 1.5 available.

  • Changing DisplayMode seems not to update Input&Graphic Dimension

    - by coding.mof
    I'm writing a small game using Slick and Nifty-GUI. At the program startup I set the DisplayMode using the following lines: AppGameContainer app = new ... app.setDisplayMode( 800, 600, false ); app.start(); I wrote a Nifty-ScreenController for my settings dialog in which the user can select the desired DisplayMode. When I try to set the new DisplayMode within this controller class the game window gets resized correctly but the Graphics and Input objects aren't updated accordingly. Therefore my rendering code just uses a part of the new window. I tried to set different DisplayModes in the main method to test if it's generally possible to invoke this method multiple times. It seems that changing the DisplayMode only works before I call app.start(). Furthermore I tried to update the Graphics & Input object manually but the init and setDimensions methods are package private. :( Does someone know what I'm doing wrong and how to change the DisplayMode correctly?

  • Ubuntu - prettier bootloader

    - by Matthew
    I hate how when I turn on the computer it just (after the hp logo, which I hate having also), shows white text on a black background. I'm wondering if there's easy ways to customize this (I'm choosing between Windows 7 and two separate Ubuntu 10.10 installs). I've read a little about some complicated ways to do this, but is there not some simpler ways by installing a package on ubuntu or something? I don't want to hack a bunch of code together to get a simple effect. I'm hoping for actual images and having like the windows 7 logo and ubuntu logo to choose from. Ideas?

  • Ubuntu Installer offers to show differences, then doesn-t

    - by R B
    When I was installing updates under 12.04 LTS today, the ubuntu installer warned that there were differences between the local copy of smb.conf and that in the installer package. It offered me a drop/down list of options. I chose one which reads something like "show differences side by side" and clicked the only available button (other than help, I think it was labelled continue) The installer then proceeded with updates and asked for a reboot. Even after rebooting, no comparison was shown. How can I find out now whether I still have my previous smb.conf or the one from the installer, and what the differences are?

  • Skype no sound on Kubuntu 13.10

    - by Michael Aquilina
    I just performed a fresh install of Kubuntu 13.10 on my machine. Everything is working great except for Skype. I cannot get any form of audio playback in Skype. In the sound settings panel I get a bunch of different sound sources, none of which work! At the moment I have set it to "sysdefault (unknown)" I installed it using the deb package found on the official website. My phonon backend is using phonon-gstreamer. When running skype from the terminal I get the following error messages: ALSA lib control.c:953:(snd_ctl_open_noupdate) Invalid CTL plughw:CARD=PCH ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave Is this a known problem or has anyone experienced the problem and managed to solve it?

  • How can I fix latency problems for car game?

    - by Freddy
    Basically I'm trying to make a online car racing game for IOS using Game Center real time multiplayer. I have setup a timer that sends data every 0.02 seconds to the other player with the current position and current angle. However sometimes, it will take LONGER then these 0.02 seconds for the package to be sent and then received. In this case i have implemented a method that "calculate" what the next position should be if no position is received based on the last position and angle. However, when the data then receives for let say 0.04 seconds after, it will change back to the last position, which will result in the car "jumping" back and lag. And If i just keep ignoring the data it will never take any input from the other user. Is their any way to prevent this? I suppose this needs to be fixed with some client-sided algorithm.

  • Licensing a project

    - by PhaDaPhunk
    Ok can someone clarify something for me ? Let's say I want to build a website and add publicity to it so I can make money out of my work. I would use Html5 for the interface and C# with Asp.net for the background programming. I would use Visual Studio as my IDE and SQL server as a database. This is just an example on the top of my head but I woudn't know where to start for the licenses. Do I need one : For VisualStudio and SQLServer only ? For VisualStudio, SQLServer and pay some kind of rights for Asp.net ? The whole package.. Both VisualStudio, SQlServer plus rights for Asp.net AND C# ? I know this question is a little vague but I really don't know where to start and the opinion of someone with experience int this might give me just the help I need to get started.

  • Thinktecture IdentityServer Azure Edition RC

    - by Your DisplayName here!
    I found some time over the holidays to finalize the Azure edition of IdentityServer. http://identityserver.codeplex.com/releases/view/81206 The biggest difference to the on-premise version (and earlier Azure betas) is, that by default IdSrv now uses Azure Storage for all data storage (configuration & user data). This means that there is no need anymore for SQL Azure (which is still supported out of the box – just not the default anymore). The download includes a readme file with setup instructions. In a nutshell: Create a new hosted service and upload your certificates Modify the service configuration file in the download to your needs (signing cert, connection strings to storage…) Deploy the package via the portal or other tools Use the new Powershell scripts to add users If you encounter any problem, please give me feedback.

  • Ubuntu 12.04 graphics crashing when GVIM opens TEX files

    - by Pdp Molniya
    I am having a little problem everytime I open GVIM to edit *.TEX files.... the menus die, windows jiggle (maximize and minimize quickly) and I get a 'internal error ' crash report from ubuntu (12.04).

  • Handling SMS/email convergence: how does a good business app do it?

    - by Tim Cooper
    I'm writing a school administration software package, but it strikes me that many developers will face this same issue: when communicating with users, should you use email or SMS or both, and should you treat them as fundamentally equivalent channels such that any message can get sent using any media, (with long and short forms of the message template obviously) or should different business functions be specifically tailored to each of the 3? This question got kicked off "StackOverflow" for being overly general, so I'm hoping it's not too general for this site - the answers will no doubt be subjective but "you don't need to write a whole book to answer the question". I'm particularly interested in people who have direct experience of having written comparable business applications. Sub-questions: Do I treat SMS as "moderately secure" and email as less secure? (I'm thinking about booking tokens for parent/teacher nights, permission slips for excursions, absence explanation notes - so high security is not a requirement for us, although medium security is) Is it annoying for users to receive the same message on multiple channels? Should we have a unified framework that reports on delivery or lack thereof of emails and SMS's?

  • Transactional Interceptors in Java EE 7 - Request for feedback

    - by arungupta
    Linda described how EJB's container-managed transactions can be applied to the Java EE 7 platform as a whole using a solution based on CDI interceptors. This can then be used by other Java EE components as well, such as Managed Beans. The plan is to add an annotation and standardized values in the javax.transaction package. For example: @Inherited @InterceptorBinding @Target({TYPE, METHOD}) @Retention(RUNTIME) public @interface Transactional { TxType value() default TxType.REQUIRED } And then this can be specified on a class or a method of a class as: public class ShoppingCart { ... @Transactional public void checkOut() {...} ... } This interceptor will be defined as part of the update to Java Transactions API spec at jta-spec.java.net. The Java EE 7 Expert Group needs your help and looking for feedback on the exact semantics. The complete discussion can be read here. Please post your feedback to [email protected] and we'll also consider comments posted to this entry.
