• Design leaderboard ratings for quiz games

  - by PeterK

  Back in March 2011 i started the following post: How to design a leaderboard? Now my quiz game have been out for approximately a year and sold pretty decently. I am working on to update the game design and is again looking into the leaderboard design to make it better as i am not happy with it. Currently i rate players on number of correct answers, which is not good as it does not consider things like number of games, difficulty levels etc. I also have "extended" stats behind the UITableView (Leaderboard). A player can play based on three levels of difficulty: hard, medium or easy Difficulty levels can be mixed between players in a game Each game can be one to six players, so there can be single games or duels Between 2 and 30 questions per game As i am considering integrating Game Center Leaderboard i need to design a better rating system so i would like to ask for some ideas how to do the rating based on the above. I am thinking about how much a point would be worth and what it includes.

• Automatically switch to workspace with active application

  - by Pit

  Hi, I currently have 4 workspaces. If I have a pidgin chat window open on one workspace that is currently not active and I get a message in that already open chat window, I want do be able to click on the green envelope symbol in the upper menu-bar and be switched to the workspace the window is situated. Currently if I click on the green envelope symbol there will be appear a button on the lower menu-bar on which I have to click to be switched to the other workspace. Same with opening links. If in some application I click on a link the last activated Firefox window will open the link. Even this last active firebox window is on a currently not active workspace, and there is a Firefox window on the currently active workspace. So either open the link in the Firefox on the currently active workspace, or switch to the workspace on which the link was opened. Is/are there any solution(s) to this problem?

• Where does node.js install to?

  - by Ash Scott

  I'm trying to install a script, which is a clone of a game, and uses node.js for it. Now, the documentation says I should copy the node.exe (windows) and put it where the clone is. Now, I can't find the node.exe ubuntu equivalent, I can't even find where it's installed?! Don't really want this hosted on a windows machine due to licensing. Here's a snipet from the doc: Download : Node.js (Install Button) Go where you are install Node.js (For Windows 8 it's C:/Programms/nodejs) Copy node.exe and paste on the clone folder Now I need to do this in ubuntu, however I can't find where node is installed to? Any ideas?

• 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?

• Why can't the Unity panel be hidden?

  - by newboldrob

  I am a light Linux user. I have Natty installed on my netbook and used to have it dual-booted on my Windows 7 PC. After a total refresh of my notebook off came Ubuntu and I'm back to basics over there. But HERE (I'm running Natty on a HP-Mini) I've decided to poke around a bit to get the best user experience on this little thing. I really like the Unity interface but really hate the static Unity Panel. I have no clue why it's even necessary to be on globally. After all, in the classic interface, both panels can autohide or get filed aside with buttons on either side of the bar. On a 10" screen, real estate is at a premium. What intrinsic purpose does the static unity panel hold for the OS? There has to be a great reason for this thing to HAVE to be here. It ONLY goes away in fullscreen apps and I can't use everything fullscreen Why can the unity panel not be hidden?

• Applications Menu disappeared [closed]

  - by Sophie Sperner

  Possible Duplicate: Applications Menu disappeared I'm using Ubuntu 12.04, classic desktop without effects. Once the indicator-applet-complete (right part of the top panel) had disappeared. I found how to fix it: Alt-Win-RightMouseClick on the panel, then "Add to the Panel", where choose "Indicator Applet Complete" to add. Now, the left part of the top panel (Applications Menu) has disappeared! If I do Alt-Win-RightMouseClick on the panel, I can add only individual Menu sections like Internet, Office, Settings etc. But how to get back the full Menu as it ought to be?

• Is It bad for SEO to have internal redirected links? [closed]

  - by Jonas Lindqvist

  I have a large number of pages having similar but not identical content. Example: site.com/dream_dictionary_flying and site.com/dream_interpretation_flying. The problem is that although not being identical, they are sometimes on the edge of being duplicate content. The solution via redirect 301 in htaccess is simple and can be done in a minute, BUT, changing all existing links on the whole site from "/something" to "/something_else" would take ages, it would be thousands of manual changes taking x hundreds of hours. My question is this; is it bad for SEO to have internal links that are redirected, or rather HOW bad is it? For the human user it would not matter at all but from what I have experienced, the search engines don't like it. Is there any rule of thumb here? Please come back with your thoughts and experience on this. Thanks!

• What's the current best practice for C multithreading?

  - by Dexter

  I've been a Java (and PHP) developer for most of my life, but will need to use C for my next project. I remember some basic stuff we did back in school with fork, pthread, semaphores, etc. but I'm not sure if that's still the "way to go" here, or if there have been any recent developments/improvements etc. Google's results seem to be fairly dated. Or does that just mean that this is still the current "state of the art"? Or will I have to use a (system-independent) libary like glib if I want higher-level abstractions, like synchronized queues? What other libraries are there? (The programm will only have to run on Linux though)

• Black screen after installing Ubuntu 11.10

  - by Abbas

  I downloaded Ubuntu 11.10 one week ago and burned it to a CD. I installed it on my system which has a 1.5 TB hard. It installed successfully and I clicked on the restart button. The computer restarted and I chose the first option, which was to load Ubuntu. A black screen would appear with a cursor in top left hand side and I think the system was hung. I repeated this process by erasing the last Ubuntu install but I faced a similar problem. Can anybody help me?

• First blog post from Surface RT using Microsoft Word 2013

  - by Enrique Lima

  One of the concerns I had in using a Surface RT was the need I have to be able to post.Recently, and not so recently, I have stopped posting. Between getting busy, carrying different devices. Well, it has been hard to do. Tried doing that with an iPad, and I can't say it didn't work, it just didn't work for me. Again, back to the concern with the Surface RT. But, looking at the App Store I started getting that same frustration I had with other platforms that left me with a feeling of "I have to compromise because I am on a SubText platform". So, I stuck to posting from Windows Live Writer (great tool!). This whole situation made me think and rethink my strategy, and then … a big DUH! What about using Microsoft Word 2013 for that? Would it work? So, here is the test!

• Not mounting/finding 1TB NTFS drive

  - by Dave

  I am having trouble with Ubuntu recognizing/finding/mounting one of my hard drives. I dual boot Ubuntu and Windows 7. I had Ubuntu 10.04 and all drives showed up under "Places" I could click on any of my Windows/NTFS drives and they would mount as they should. I have since updated to Ubuntu 10.10. One of my drives no longer shows up in "Places" or in Nautilus. I can open gparted and it is listed there, but if I try to click the mount button, I get an error. I am currently at work and can not post any screenshots or errors, but will happily do so later. I was just hoping that someone might be able to give me something to try when I get home. 250gig SATA hard drive (Windows7/NTFS) - recognized/mountable 200gig PATA hard drive (Ubuntu 10.10) - recognized (obviously) 1TB SATA hard drive (NTFS) - not recognized/won't mount Thanks!

• Uploading or attaching files that located on a shared drive doesn't work?

  - by Alex

  I have this odd, quite minor, but annoying issue that I am quite perplexed about. Whenever I try to upload a file via my browser(let's say attach a file to an email in GMail), I click 'Browse' button and it opens standard file selection dialog, that doesn't show network drives. Further more if I try to drag a file from a network drive into GMail, it doesn't work either, it just doesn't let me do that. This issue has been around for quite sometime now, and I am just curious if this is something on my side or if it's a bug or a misconfiguration of some sort. FWIW, I am currently running 10.10, network drive is a samba share on NAS. This happens in FF and Chrome and this is only happens with Samba mounts. As a matter of fact, NFS volumes that are located on the same network operate perfectly fine.

• How do I shutdown 12.10 when ACPI is set to OFF?

  - by rahi

  I recently installed 12.04 on an HP Spectre XT ultrabook. I installed 12.04 from a USB. When the install was complete, and the computer restarted, I got a blank screen. After some searching, I found that I had to choose "acpi=off" during the installation, which now shows up in the grub screen. Once I was on 12.04, I upgraded to 12.10. The issue now is that when I hit shutdown, the computer hangs on a purple shutdown screen. Usually, at this point, I press the power button on the machine to completely power off the machine. I am new to ubuntu, and would appreciate the help. Thanks.

• Xamarin Wins Funding, Microsoft Builds Repair Tool

  Let's focus on the Xamarin news first. Xamarin is a young company with a phoenix-like history. Founded in May of 2011 by Miguel de Icaza and the rest of the team that created Mono, Xamarin got its start, effectively, as Ximian (de Icaza's previous company). Ximian was founded way back in 1999, and created Mono, which TechCrunch describes as an open source project that brings Microsoft's .NET development framework to non-Microsoft operating systems like Android, iOS and Linux. Novell acquired Ximian inn 2003, and continued to fund Mono's development. But apparently, when Attachmate bought No...

  - by Jason Fitzpatrick

  The proliferation of streaming services and diverse media content has made cutting the cable cord an appetizing option for many people.
