  • How are larger games organized?

    - by Matthew G.
    I'm using Java, but the language I'm using here is probably irrelevant. I'd like to create an economy based on an ancient civilization. I'm not sure how to design it. If I were working on a smaller game, like a copy of "Space Invaders", I'd have no problem structuring it like this. Game -Main Control Class --Graphics Class --Player Class --Enemy class I'd pass the graphics class to both the player and enemy class so they could call graphics functions. I don't understand how I'd do this for larger projects. Do I create a country class that contains a bunch of towns? Do the towns contain a lot building class, most contain classes of people? Do I make a path finding class that the player can access to get around? How exactly do I structure this and pass all these references around? Thanks.

  • Ambiance GTK theme customisation *just* for one user

    - by Robottinosino
    Is it possible to customise the appearance of the Ambiance theme just for one user? I have read about the possibility of doing this: sudo vim /usr/share/themes/Ambiance/gtk-2.0/gtkrc but could something be done to change: just one setting for just one user? Perhaps changing something in the user's .themes directory? Notice: I would prefer not to copy the full theme to the user directory, just to provide an override mechanism after the "global" theme is applied, independently from the theme if possible, but anyway just specifying what needs to be different, not duplicating the whole theme definition.

  • Ubuntu "Server" but with a better terminal?

    - by RiMMER
    I'm currently using Ubuntu Server installed in VirtualBox for running various server services. The only drawback it posses for me is that I cannot use mouse in the terminal and select/copy/paste stuff. What would be an alternative in this situation to get a better terminal? I guess Ubuntu Server itself doesn't support mouse, so I'd have to go for Ubuntu Desktop, but it seems like a huge waste of resources to run Unity/Gnome3 in VirtualBox only to have a terminal. So then I'm wondering whether Xubuntu/Lubuntu would be suitable alternatives, although they still take a lot of time to boot up, etc. Any ideas how to solve this scenario?

  • What sources of sample work should be used in a job interview?

    - by Joan Venge
    One of my friends has been laid off. When I talked to him, he said they didn't let him take a copy of anything he worked on. When he asked how to show what he worked on to another employer in an interview, he was told that he will have some explaining to do. Should we, as programmers, be allowed to take samples of our previous work former employers? What sources of code should we be expected to show off in an interview? When almost every employer asks for sample work, how are we to justify what can be sent? Is it our responsibility to maintain after-work projects for our entire life so we have code we can legally show to our next employer?

  • Is there a limit on the number of threads that can be spawned simultaneously?

    - by georgesl
    Yesterday I came across this question: How can i call robocopy within a python script to bulk copy multiple folders?, and I though it might be a good exercise for multithreading. I though of spawning as many threads as files needed to be copied, each routine having an exception handling system to prevent the whole copying process from crashing (and log -using mutex on the log file - if there was an error). My question: Is there a limit on the number of thread you can spawn almost simultaneously? If yes, what is the limiting factor? My question is focused on PC desktop, but I welcome any answer on different hardware (embedded systems, calculus clusters, etc.).

  • Where can I get fresh new Wine DLLs?

    - by SuperScript
    I was acting careless today and I accidentally deleted one of the .dlls in my Ubuntu Wine installation, ~/.wine/drive_c/windows/system32/ole32.dll to be exact, and need a new fresh copy of only this one .dll. I know that reinstalling will fix it, but I have installed quite a few programs and do not want to have to do such a drastic thing just to fix this one problem. So, I'm wondering if there is somewhere that I can download this original .dll as it came with my original Wine installation. I have found the SourceForge repository, but it only has .h and .c files and I do not know how to build them into a .dll. Can anyone give me a link to download, or instructions to build my missing .dlls?

  • 14.04 missing "/etc/init.d/ufw"? my firewall never auto starts

    - by Aquarius Power
    I need to know how to fix the missing "/etc/init.d/ufw" file, is it some package or some command? I used the gufw to enable it, but on reboot my firewall was still off... I created a symlink /etc/init.d/ufw -> /lib/init/upstart-job but I could not make it work like start ufw. I found this file /lib/ufw/ufw-init, it looks like a init.d file! can I copy or symlink it there? Additional (optional) questions: How to find what package has that file? apt-cache search didnt work.. Can we safely create such a script? Any idea why is it missing? Obs.: my /etc/ufw/ufw.conf has ENABLED=yes (but seems useless..)

  • How to indicate a page is duplicate content when you control its body but not its head?

    - by tog22
    http://www.zcommunications.org/ready-or-not-can-bangladesh-cope-with-climate-change-by-hazel-healy is a copy of a page on our site created by the author, and links back to that page. Google's guidelines suggested to me that this would be enough for Google to recognise our page as the canonical one and that one as the duplicate, and thus to show our page in SERPs. However, the opposite has happened - if you search for the page's title you'll see the duplicate page shows up but ours doesn't. How can we prevent this? Since the author 'owns' the duplicate page on zcommunications.org she can edit the HTML body, but not the <head>.

  • I've totally missed the point of distributed vcs [closed]

    - by NimChimpsky
    I thought the major benefit of it was that each developers code gets stored within each others repository. My impression was that each developer has their working directory, their own repository, and then a copy of the other developers repository. Removing the need for central server, as you have as many backups as you have developers/repositories Turns out this is nto the case, and your code is only backed up (somewhere other than locally) when you push, the same as a commit in subversions. I am bit disappointed ... hopefully I will be pleasantly surprised when it handles merges better and there are less conflicts ?

  • How can I make Banshee re-encode FLAC to Ogg Vorbis when copying to my player?

    - by Michael E
    I have most of my music in FLAC on my large storage device, and would like to automatically re-encode it in Ogg Vorbis when copying it to my portable audio player (Sansa Fuze v2). I have set my Fuze to MTP mode and told Banshee to encode to Ogg Vorbis with quality 4 in the Device Properties dialog for the Fuze (I would use MSC mode, but don't have an encoding option in the device properties when I do that). However, when I copy music to the device, either by dragging it from the music library or by syncing a playlist, the full FLAC files are copied rather than transcoded and written as Oggs. How can I get my Banshee setup re-encoding the audio? If StackExchange supported bonus points, I'd give bonus points for a solution that only re-encoded music that was already losslessly encoded, but I don't think that's possible.

  • Free Website Content - Do Articles From Directories Work Anymore? Part 2

    A clever strategy for many SEO experts is to study a site that is ranked highly and then try to copy what those sites do to get so successful. Take a close look at highly ranked sites and you will notice that virtually all of them have a very high number of links pointing to other sites. Let me give an example of a site that is ranked very highly and is exclusively made up of links pointing to other sites, billions of them in fact. I am talking about a site that receives over 100 million hits daily. Learn their secrets in this article.

  • Install Ubuntu 12.04 on Drive "D"?

    - by Bill Jones
    I have a Dell Inspiron 531S that originally came loaded with Windows Vista. A couple years ago I purchased a copy of Windows 7, formatted the hard drive and installed the updated operating system. In the process I formatted the 10 GB recovery drive partition on drive D as it was no longer needed for Windows Vista. I would really like to install Ubuntu 12.04 LTS alongside Windows 7 using the empty 10 GB drive D:. I have two questions. (1) Can Ubuntu be installed on a separate partition, a drive removed from the boot sector on drive C:? (2) If so would Grub be installed in the boot sector and properly select Windows 7 on drive C: or Ubuntu 12.04 on drive D?

  • Possible / How to render to multiple back buffers, using one as a shader resource when rendering to the other, and vice versa?

    - by Raptormeat
    I'm making a game in Direct3D10. For several of my rendering passes, I need to change the behavior of the pass depending on what is already rendered on the back buffer. (For example, I'd like to do some custom blending- when the destination color is dark, do one thing; when it is light, do another). It looks like I'll need to create multiple render targets and render back and forth between them. What's the best way to do this? Create my own render textures, use them, and then copy the final result into the back buffer. Create multiple back buffers, render between them, and then present the last one that was rendered to. Create one render texture, and one back buffer, render between them, and just ensure that the back buffer is the final target rendered to I'm not sure which of these is possible, and if there are any performance issues that aren't obvious. Clearly my preference would be to have 2 rather than 3 default render targets, if possible.

  • How do non-coders do simple local templating to avoid redundant HTML? [closed]

    - by Max Cantor
    I'm a web developer. When I start designing a site, I use a framework to handle templating for me, even if it's just rack + erubis. What do non-developers do? If you want to implement a site in HTML and CSS without a framework running on a webserver, without frames, and without WYSYWIG tools like Dreamweaver... how do you avoid copy-and-pasting the HTML of your navigation (for example) on every single page you're writing? I feel stupid asking this because it seems like their must be an obvious answer, but for the life of me, I can't think of one right now.

  • Is adding in the header the license type enough to say: "my code is licensed"?

    - by silverfox
    I read on various sites about licenses. I did just put the license type in the header file (in my case a javascript file, open-source): /* * "codeName" "version" * http://officialsite.com/ * * Copyright 2012 "codeName" * Released under the "LICENSE NAME" license * http://officialsite.com/LICENSE NAME */ javascript code ... In the same folder I leave a copy of the license. The listing of the folder looks like this: * codeName.js * LICENSE In the file LICENSE is the full text of the license my code uses. What I cannot find anywhere that says is this is enough to say my code is licensed (the case of open-source). Is something more required?

  • How to make the apt autocompletion work in minimal system (in LXC container)?

    - by Adam Ryczkowski
    When I work inside thin LXC container on 12.04 I have only very basic system. In particular the /etc/bash_completion.d is missing the e.g. apt, that I find particularly useful. Is there any standard package, that installs the autocompletion for the apt, or should I copy the file manually? And just copying the files into /etc/bash_completion.d manually just doesn't seem to work. I use bash as my command interpreter. What am I missing here?

  • How to get KeePass to properly work with Chromium?

    - by Tom
    The two-channel auto-type obfuscation feature of KeePass doesn't work for me with Chromium (on Ubuntu 12.04 64 bits). However, it works just fine with Firefox. Dows anyone know how to fix this? Textboxes in web forms in Chromium seems to have something special that causes this feature to fail. Only some of the username/password characters are being auto-typed. This might be related to this: if I select an entry in KeePass and click "Copy User Name", I can paste it fine with Ctrl+V in any textbox in Firefox, but I can't on Chromium. However, text copied using Ctrl+C from a regular text file (say, from gedit), can be pasted fine on both browsers. What may be wrong? I wouldn't like to deactive this feature for all the entries in my keepass files as I use them on Windows too and they work just fine there (even on Google Chrome for Windows). This feature gives an appreciated extra security measure against spyware/keyloggers.

  • which Project hosting service (Like google code, github) you will prefer to use? And Why?

    - by MobileDev123
    I am using to study (and at some point of time copy the desired module of) the code from these two sites (Google Code and Github). There is sourceforge too, I have some code, say some library that I want to share with the community, and I am to decide the hosting site. And before I decide I want to have opinions from this community. Which is your favorite Project hosting site or service? And why? There is one point where github can win over google code (may be I am wrong here), Github can let you forge whole project with a zip or tar file, but to do the same in google code we have to upload the zip file explicitly and put it in downloads.... Thanks

  • Stateless game design

    - by L. De Leo
    I'm facing a challenge understanding how to program a web version of a card game that is completely stateless. I create my object graph when the game begins and distribute cards to PlayerA and PlayerB so I lay them out on the screen. At this point I could assume that HTML and the querystring is what holds at least some of my state and just keep a snapshot copy of the game state on the server-side for the sole purpose of validating the inputs I receive from the web clients. Still it appears to me that the state of the game is by its nature mutable: cards are being dealt from the deck, etc... Am I just not getting it? Or should I just strive to minimize the side-effects of my functions to the objects that I take as my input? How would you design a stateless card game?

  • Syncing Files between workgroup server and Ubuntu workstation

    - by dotdawtdaught
    Recently I have decided that I can't make Windows 8 my primary OS on my laptop as it is just too cumbersome to deal with. I am made the switch to Ubuntu and so far so good. Using Windows I have been able to cache folders on my workgroup server using a feature called "Client Side Cache" that allows me to take a copy of my personal files offline while I am in the field, then later I when I return any changes get pushed up to the server and my local cache is refreshed. This feature is completely client driven although characteristics of it (who and what can be cached, and if caching is automatic) can be controlled via a policy assigned as part of a directory membership. Can anyone suggest a linux replacement for this feature? Is there a better way of handling this?

  • Upstart Script: Detect Shift Key Down At Boot

    - by bambuntu
    I want to create a boot up potential which allows a different upstart/runlevel configurations to load based upon specific key downs at boot (or combos). How do I detect a key down event with an upstart script? I'm offering a bounty. The deal is you must provide a very simple piece of working code to do this. I will immediately check the code and verify that it works. I'm on 10.04 if that helps. Alternative methods to achieve the same result are acceptable, i.e., if grub could somehow show entries that would indicate a type of boot, where that boot would cp appropriate files to /etc/init. So, instead of a keydown solution, it would be a boot menu item solution and the way to get grub to copy upstart scripts to /etc/init. If possible.
