  • game play strategy in an arena

    - by joulesm
    I am writing a player's behavior for an arena game, and I'm wondering if you can offer some strategies. I'm writing it in Python, but I'm just interested in the high level game play. Here are the game aspects: Arena is a circle of a given size. The arena size shrinks every round to help break ties. Players are much smaller circles, can be on teams of 1 or 2 players. Players attack by colliding with other players, and based on the physics of the collision (speed of both players, angle), one could force another player out of the arena. Once a player is out of the arena, they are out of the game (for that round). The goal is to be the only team with players left in the arena. All other players have been pushed (through collisions or mistakes) out of the arena. It is possible for there to be no winner if the last two players exit the arena at the same time. Once the player has been programmed, the game just runs. There is no human intervention in the game. I'm thinking it's easiest to implement a few simple programmatic rules for my player to follow. For example, stay close to center of the arena, attack opponents from the inner side of the arena, etc. Are there any good simple game strategies? Would adding a random aspect to the game help? For example, to avoid predictability by the other team or something. Thanks in advance.

  • Please, tell us how you made Agile work for you?

    - by Paul
    I've been seeing many questions related to Agile. There seems to be confusion between the people who are doing Agile successfully, and those of us who don't understand it. So I'm wondering if some of the successful teams would be willing to give the result of us some examples of how you succeeded. Some of the things I know I wonder What steps did you use? (ie. Talk to users, mock up, tests, code, testing, (whatever)) Tools that helped you? Did you generate any artifacts, other than a working implementation? How did you prevent spaghetti architecture / code? How do you pass along to new team members, or is the team stable for the project How did you determine exit criteria, or was it open ended. (Scope of project?) Did you do this as contracting? How did you develop a contract up-front? Did the business do any up front work? Or did they come to the table with "We want to implement a "bleh bleh blah"? What types of tests did you use? Unit, Integration, UAT? Or did the process make some/all of those unnecessary? Bonus: Do you have an situations / links to "How To" Agile articles, books, etc? Wiki, describes what but not how (to the uninitiated) At least to me, not a duplicate

  • Shutting down Ubuntu 11.10 with power button without x11-session

    - by RJdaMoD
    when pressing the power-button inside a (gnome-)session, ubuntu asks me what to do and shuts down after 60 seconds anyway. No problem so far. But if i'm not logged in in a gnome-session (for example in the login screen), or just change to a tty, then the power-button won't work. But i remember that i worked in 11.04. So what's changed and how to restore? Background: I use my machine as a print server. If im not home and my wife wants to print sth., she used to switch on my machine, print via her laptop, and then just shut it down by power-button. Beginning of march i was on a business tour, and she called me that she could not shutdown my machine anymore. I shut it down by ssh, but this seems not the favorable way to me. I already had a look in /etc/acpi/powerbtn.sh and think that the line if pidof x $PMS > /dev/null; then exit is the cause for this since it aborts the script when no gui-power-manager is found. Is that right? But that does not explain with the power-button does not work when switching from the x11-session to a tty, although this would not be critical to me. Thanks in advance Greetings RJ

  • hd0 out of disk error results to low graphics mode

    - by msPeachy
    Yesterday, I have reinstalled Ubuntu due to a error: hd0 out of disk on boot. Everything went fine, I've installed apps, perform updates and upgraded the kernel. I've even restarted it a few times just to check if I would encounter boot issues and was glad that everything was working perfectly, then powered it down. The next morning when I boot, I got this error: hd0 out of disk error. Press any key to continue... again! After pressing a key, it took 10 minutes for the Ubuntu logo to appear with it's 5 dots. After another 5 minutes, Ubuntu started checking the disk and displayed a message that / has errors, I pressed F to fix the errors. After which Ubuntu tells me that /tmp is not yet ready for mounting so I pressed S to skip mounting it, then Ubuntu restarted. On boot I saw the error: hd0 out of disk error. Press any key to continue... again. This time it took only a minute for the Ubuntu logo to appear and after another minute a dialog box appeared with the following message: The system is running in low-graphics mode. Your screen, graphics card, and input settings could not be detected correctly. You will have to configure these yourself. What would you like to do? Run in low-graphics mode for just one session Reconfigure graphics Troubleshoot the error Exit to console login Whichever option I choose I ended up with a console prompt: grub-editenv: error: cannot read the file /boot/grub/grubenv. _ I can't do anything on this console, whatever I type nothing happens. I've rebooted several times and I get same error every time. I don't quite understand what is wrong with Ubuntu or with my installation. I've encountered this hd0 out of disk error several times already and always ended up reinstalling. I'd really really appreciate it if you guys can help me fix this. Thank you and good day.

  • Applying Service Pack 1 to Team Foundation Server 2010

    - by Enrique Lima
    Disclosure:  I performed the following activities on my Windows 7 SP1 system, Visual Studio 2010 SP1 and a local Basic installation of TFS 2010. As with any deployment of a service pack into a server environment, take your recommended precautions and be aware of the changes you are putting in.  With that said, make sure you backup your databases, and that you have an exit/rollback strategy in the event of an unexpected situation. Team Foundation Server 2010 Service Pack 1 corresponds to KB2182621.  The KB article is http://support.microsoft.com/kb/2182621 The process will be very simple to follow, you will need to execute the mu_team_foundation_server_2010_sp1_x86_x64_651711.exe file.  That will extract files needed and launch the wizard driven Installation. Once this process completes, you need to validate the changes. By looking at Team Foundation Server 2010 Administration Console, you should see the reference to the KB number and SP1. There is also a good reason to validate log locations and records. From the Team Foundation Server 2010 Administration Console. Or from Windows Explorer, go to the C:\ProgramData\Microsoft\Team Foundation\Server Configuration\Logs location and review the logs referenced by the servicing references.

  • How can I make smoother upwards/downwards controls in pygame?

    - by Zolani13
    This is a loop I use to interpret key events in a python game. # Event Loop for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() if event.type == pygame.KEYDOWN: if event.key == pygame.K_a: my_speed = -10; if event.key == pygame.K_d: my_speed = 10; if event.type == pygame.KEYUP: if event.key == pygame.K_a: my_speed = 0; if event.key == pygame.K_d: my_speed = 0; The 'A' key represents up, while the 'D' key represents down. I use this loop within a larger drawing loop, that moves the sprite using this: Paddle1.rect.y += my_speed; I'm just making a simple pong game (as my first real code/non-gamemaker game) but there's a problem between moving upwards <= downwards. Essentially, if I hold a button upwards (or downwards), and then press downwards (or upwards), now holding both buttons, the direction will change, which is a good thing. But if I then release the upward button, then the sprite will stop. It won't continue in the direction of my second input. This kind of key pressing is actually common with WASD users, when changing directions quickly. Few people remember to let go of the first button before pressing the second. But my program doesn't accommodate the habit. I think I understand the reason, which is that when I let go of my first key, the KEYUP event still triggers, setting the speed to 0. I need to make sure that if a key is released, it only sets the speed to 0 if another key isn't being pressed. But the interpreter will only go through one event at a time, I think, so I can't check if a key has been pressed if it's only interpreting the commands for a released key. This is my dilemma. I want set the key controls so that a player doesn't have to press one button at a time to move upwards <= downwards, making it smoother. How can I do that?

  • How to remove all associated files and configuration settings of an app installed through 'force architecture' command

  • Minimum percentage of free physical memory that Linux require for optimal performance

    - by csoto
    Recently, we have been getting questions about this percentage of free physical memory that OS require for optimal performance, mainly applicable to physical compute nodes. Under normal conditions you may see that at the nodes without any application running the OS take (for example) between 24 and 25 GB of memory. The Linux system reports the free memory in a different way, and most of those 25gbs (of the example) are available for user processes. IE: Mem: 99191652k total, 23785732k used, 75405920k free, 173320k buffers The MOS Doc Id. 233753.1 - "Analyzing Data Provided by '/proc/meminfo'" - explains it (section 4 - "Final Remarks"): Free Memory and Used Memory Estimating the resource usage, especially the memory consumption of processes is by far more complicated than it looks like at a first glance. The philosophy is an unused resource is a wasted resource.The kernel therefore will use as much RAM as it can to cache information from your local and remote filesystems/disks. This builds up over time as reads and writes are done on the system trying to keep the data stored in RAM as relevant as possible to the processes that have been running on your system. If there is free RAM available, more caching will be performed and thus more memory 'consumed'. However this doesn't really count as resource usage, since this cached memory is available in case some other process needs it. The cache is reclaimed, not at the time of process exit (you might start up another process soon that needs the same data), but upon demand. That said, focusing more specifically on the percentage question, apart from this memory that OS takes, how much should be the minimum free memory that must be available every node so that they operate normally? The answer is: As a rule of thumb 80% memory utilization is a good threshold, anything bigger than that should be investigated and remedied.

  • What will be the better way for data retrieval on application that needs to handle limited amount of data?

    - by Milanix
    Just moved this question from Stack Overflow. Since, adding my code snippets itself would make this question really long. Instead, I am pretty interested in knowing a better ways for data retrieval on application that needs to handle limited amount of data which isn't updated regularly. Let's take this example: I am writing an application which gets a schedule as an XML from server. I have written a logic in order to parse XML version and update database only if the version is newer than the local version. Although the update is checked automatically/manually on daily basis based on user preference, the actual version update happens only once per few months or so. Since, this is done by some other authority which doesn't provide API but, rather inform publicly on their changes. The actual XML contains a "(n number of groups)(days in a week) (n number of schedule)" . The group is usually 6 and the number of schedule is usually 2. So basically there would usually be only around 100 strings. Now although I have used SQLite at the moment. I want to know how to make update on database. Should I show progress dialog that the application is updating and exit the app when it's done? Since, my updates are infrequent i don't think this will really harm user experience but, is there any better ways to do it? Because I don't want update to be made when user is searching which is done using database. This will cause an database already open exception. At least I have faced this problem before. Is it better to rather parse XML every time when user wants to view certain things or to use SQLite? Since, I make lots of use of adapter in my app to create lists, will that degrade the performance?

  • Cannot get script to run at startup (tried all the simple answers)

    - by Carey Head
    I have Ubuntu Desktop 12.04 LTS running great on an older Acer desktop. I want to use this machine as an in-home server for hosting Minecraft. The command to start the Minecraft server is java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui and that works great when I cd into the correct directory and execute the above. I created a script to do this: #!/bin/bash cd /home/myuser/minecraft-server1 java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui & cd /home/myuser/minecraft-server2 java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui & exit 0 I made this .sh file executable, and it too runs great when I start it manually from the terminal. The problem I'm having is getting these to execute at startup. I have my user account on this machine to auto login. I have tried the following: Adding the following to "Startup Applications" : sh /home/myuser/myscript.sh (Nothing happens on reboot) Adding the same to /etc/rc.local (Nothing happens on reboot). I even tested this one by running /etc/rc.local from the terminal, and it executed great. Just not at boot/auto login Added the lines from the script directly to rc.local (Nothing happens on reboot). I can't help but think that there's something I'm missing. The script executes great when run manually, but will not run at boot/auto login. Many thanks in advance.

  • CLR Profiler Allocated Bytes and XNA ContentManager

    - by Vackup
    I've been fighting with XNA ContentManager and memory allocations for some weeks because I'm trying to port my game from XNA (Windows) to ExEn / Monotouch (iphone). The problem is that after playing a few levels, my game exits unexpectedly on a real iPhone device (not simulator). Profiling memory usage on Windows with CLRProfile, I found some useful stuff but I also found something I dont understand. If I use 2 ContentManagers (1 for shared assets and 1 for level assets), when profiling, "Allocated Bytes" grows and grows after level through level but Memory consumption measured by Windows Task Manager stays constant (down when I unload the content manager and up again when I load content). Obviously, I contentManager.Unload() when level ends. After a few levels my game exits unexpectedly on an iPhone device. If I use 1 content manager, "CRLProfiler Allocated Bytes" stays constant on Windows and on the iPhone; I can play the game normally and it doesnt exit unexpectedly. I use the same assets level through level. It seems like in ios (iPhone) when loading and unloading the same assets, it allocates memory and consumes all device memory, so the ios kill it. Can anybody explain me how this really works? I've read quite a bit, but I still don't understand what's going on.

  • Unable to start Ubuntu 12.04. The system is running in low-graphics

    - by kaleidoscpicsoul
    I am a newbie to Ubuntu. I installed Ubuntu 12.04 using a USB Stick and it was running all fine for a few weeks and this error popped up. According to one of my friend, the best way was to re-install Ubuntu. Being from a non unix background i thought the same too and after the second install it happened again, but only this time was much quicker, in 3 days. I don't want to re-install Ubuntu every time this happens. I am a complete newbie to Linux which means that i am really bad at using terminal. I know there are other people who fixed this issue using this very same forum, but unfortunately the answers provided are too complex for me to understand. Please let me know how to do this. Things I want to let you know: I would need help step by step if that is alright with you. After i get the error i get the options and i click exit to console login I get the following message in a black screen (which i think is a command line sort of thing): * Stopping save kernel messages [OK] apache2: Could not reliably determine the server's fully qualified domain name,using 127.0.1.1 for ServerName [OK] * Starting web server apache2 and a blinking cursor. So basically it looks like a dead end for my non unixy eye. And one final thing is before this issue had happened i had tried configuring Python to Apache2. For that i had uninstalled and installed LAMP server several time and edited the configuration files too. I don't know if this really is a concern, but I don't know.. I have a USB with Ubuntu 12.04 in it so i can install it anytime. (But i want to know what the issue is rather than running away) . I migrated to Ubuntu from Windows and i have no plans to go back. I think that's from my side. Please let me know if there are any questions.

  • Facebook contest policy no-no?

    - by Fred
    I would like to post a link on a Facebook page where it will exit Facebook entirely and go to a client's website, where people will be on a page (client's) where they can enter their e-mail address to be entered in a temporary database file with rules and disclosures etc., for a draw once the number of entries reaches 100 for instance. Once the number of entries reaches 100, a random winner is picked and notified via E-mail. The functionality is as follows: A link is place on a Facebook page leading to an external page The page is a form to merely enter their email address for a contest The email is placed in a temporary file An automatic E-mail is sent to the address used for confirmation using SHAH-256 hash The person receives the Email saying something to the affect "Please confirm your Email address etc. - If you did not authorize this, simply ignore this message and no further action will be taken". If the person clicks on the confirmation link, the Email is then stored in the database and the person is again notified saying "Thank you for signing up etc." Once others do the same process and the database reaches a certain number, the form is no longer accessible and automatically picks a random Email. Once picked, an Email is automatically sent to the winner stating the instructions, and notifying me also. Once that person clicks yet another confirmation link, the database is then automatically deleted. I have built this myself and have no intentions of breaking any rules, nor jeopardize the work/time/energy I have put into this project. Is this allowed?

  • Can't install on a Thinkpad W700ds

    - by Habstinat
    I want to install Ubuntu on my computer. I don't know much about Linux, but I know my way around a terminal and whatnot. My computer, a ThinkPad W700ds, refuses to read from my CD when booting. The md5sum is correct and the same CD boots fine from another computer. When I try to install from a USB, I can get the main screen, but when I select any of the options from there my screen turns black for more than 3 hours until I have to turn it off. Is there anything I can do about this? I want to have a true partition, don't want a Wubi'd install. It's a 10.10 x64 image, but my computer is 64 bit (running Windows 7 x64 right now) and the exact same CD is bootable on other computers. I've been on #ubuntu IRC for days trying to work this out but nobody knew, so I figured I would get more responses by posting to here. UPDATE: Thanks Jorge Castro. Both the alternate and desktop installers seem to not work at all with the CD. On a USB, the alternate installer lets me start installing, but in the middle of installation I get this message. The people on #ubuntu told me to just exit installation at that point, so I did.

  • Ubuntu 12.04 fresh install wont boot up

    - by user147220
    im running ubuntu 12.04 and it refuses to boot up. the screen will come on for a second, the mosue will appear, then itll go black again all inside about 3 seconds. i let it just do that for a while and eventually a window popped up saying i had a display issue. I didn't have a mouse but there was a button saying "ok" at the bottom that i couldnt click on. i hit enter, got through that screen, now im looking at another that says "What would you like to do?" - run in low-graphics mode for just one session - reconfigure graphics - troubleshoot the error - exit to console login then two buttons, cancel, and ok. I dont have a mouse and its not letting me navigate between these options with tab. firstly, if i make it through these windows will it get me into the computer so i can try and fix whats going on? also, whats going on here? also, how can i click on these buttons without the use of tab or a mouse?

  • Dropping multiple objects using an array in Actionscript?

    - by Eratosthenes
    I'm trying to get these fireBalls to drop more often, I'm not sure if I'm using Math.random correctly. Also, for some reason I'm getting a null reference because I think the fireBalls array waits for one to leave the stage before dropping another one? This is the relevant code: var sun:Sun=new Sun var fireBalls:Array=new Array() var left:Boolean; function onEnterFrame(event:Event){ if (left) { sun.x = sun.x - 15; }else{ sun.x = sun.x + 15; } if (fireBalls.length>0&&fireBalls[0].y>stage.stageHeight){ // Fireballs exit stage removeChild(fireBalls[0]); fireBalls.shift(); } for (var j:int=0; j<fireBalls.length; j++){ fireBalls[j].y=fireBalls[j].y+15; if (fireBalls[j].y>stage.stageHeight-fireBall.width/2){ } } if (Math.random()<.2){ // Fireballs shooting from Sun var fireBall:FireBall=new FireBall; fireBall.x=sun.x; addChild(fireBall); fireBalls.push(fireBall); } }

  • Thunderbird: "Could not initialize the application's security component" [closed]

    - by user unknown
    In Thunderbird, on startup, I get the error message: "Could not initialize the application's security component" The message continues to check permissions of the profile, and free disk space. df -h shows, that I have 19G free disk space. find . -not -perm -644 -not -perm -600 -ls shows: No file without rw-permissions for me. Before the error occured, thunderbird worked well. But I changed my main mail-account. I had two, let's call them A and B, and used mainly A, but now I wanted to deaktivate it, and receive and send automatically via the second. I Had problems moving the filters from inbox A to inbox B (missing copy-functionality). In the web, I found (mollazine) hints, to move key3.db, cert8.db and secmode.db out of the way, but it didn't work for me. Another hint was to uninstall Quickcam(?. sic!), but I don't have Quickcam. A third to recreate the profile, but I have subdirectories, filters, addressbook, groups - mails back to the year 2003. I don't want to risk the loss of data. The whole errormessage is: Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features. When I open the error-console, it is empty.
