  • Putting Together a Game Design Team?

    - by Kaia
    I'm attempting to put together a game design team that is willing to help me design/program, test, and somewhat produce the game we make to the public. I need anyone who knows anything about programming/coding, designing, etc. Once we get it up and running and out into the world (over dramatic maybe? haha) I have ideas of generating a profit from it so there is a possibility of payment. My thinking on it (so far) is this: 2D (possibly. I haven't decided if I want it 2D or 3D. It really depends on what is easier) 3rd person. Adventure (I want there to be a point to it, but like a point with no real end) I want there to be a story to it. If you've ever played Dofus, think like that. There is a story to the game, but no real end. I want (if possible) to include mini-games. These could end up becoming a possible way for a player to aquire in-game money, quest items, etc. If anyone is interested in helping me create the story line/script (which we will finsih first, before creating the game) please contact me. I want to get this completed as soon as possible.

  • How to allow password protected start-stop-daemon functionality?

    - by Mahmoud Abdelkader
    I would like to use Ubuntu's start-stop-daemon to start my application, but the application protects some sensitive information, so I have a mechanism where the application prompts for a password that's then used to generate a hashkey, which is used as the secret key for a symmetric encryption (AES) to encrypt and decrypt things from a database. I'd like to daemonize this application and have it run from start-stop-daemon, so that sudo service appname stop and sudo service appname start would work, but, I'm not sure how to go about doing this with the added complexity of a password prompt. Is there something that supports this or do I have to program it from scratch? I figured I should ask first before re-inventing the wheel. Thanks in advance.

  • What is an appropriate language for expressing initial stages of algorithm refinement?

    - by hydroparadise
    First, this is not a homework assignment, but you can treat it as such ;). I found the following question in the published paper The Camel Has Two Humps. I was not a CS major going to college (I majored in MIS/Management), but I have a job where I find myself coding quite often. For a non-trivial programming problem, which one of the following is an appropriate language for expressing the initial stages of algorithm refinement? (a) A high-level programming language. (b) English. (c) Byte code. (d) The native machine code for the processor on which the program will run. (e) Structured English (pseudocode). What I do know is that you usually want to start your design implementation by writing down pseuducode and then moving/writing in the desired technology (because we all do that, right?) But I never thought about it in terms of refinement. I mean, if you were the original designer, then you might have access to the original pseudocode. But realisticly, when I have to maintain/refactor/refine somebody elses code, I just keep trucking with the language it currently resides in. Anybody have a definitive answer to this? As a side note, I did a quick scan of the paper as I havn't read every single detail. It presents various score statistics, can't find where the answers are with the paper.

  • install android sdk on kubuntu

    - by dot
    I'm trying to follow the instructions for installing the android sdk found here: http://developer.android.com/sdk/installing/adding-packages.html After i've unpackaged and i run the android program under tools, I don't get all the options that I'm supposed to. The only 2 folders that show up are tools, and extras. Under tools, it only shows the "Android SDK Tools" with the status "Installed". Under the "extas" folder, I have nothing. I've made sure that my http: proxy settings are correct. And I've checked the logs. there are no errors. According to the android developer site, I'm supposed to install the SDK platform tools. has anyone tried this on ubuntu? I also checked and saw others were instructed to do an apt-get install ia32-libs but it failed for me. Besides which, I am running the 32bit os... so I don't think i would need to install that... ?? I've also tried following the instructions found here: http://forums.team-nocturnal.com/showthread.php/772 But... I can't seem to add the personal archive nilarimogard without getting an error message. when i attempt: sudo add-apt-repository ppa:nilarimogard/webupd8 I get the message: Traceback (most recent call last): File "/usr/bin/add-apt-repository", line 125, in ppa_info = get_ppa_info_from_lp(user, ppa_name) File "/usr/lib/python2.7/dist-packages/softwareproperties/ppa.py", line 80, in get_ppa_info_from_lp curl.perform() pycurl.error: (7, "couldn't connect to host") root@jll:/home/me/Documents# any suggestions?

  • Import Java Trusted Certificate to JRE

    - by Zalastax
    I need to install a certificate from a Java app to a lot of people. I want to use a one click program or batch file to import it as a Trusted Certificate(in Control Panel-Security-Certificate). Then they won't need to press always allow first time they use the application. I have extracted the needed certificate as both a .csr and as a .cer (the .csr via Control Panel and the .cer via keytool). Now I need to get one of them back without any clicking in menus. I don't really understand the documentation of importing .cer with keytool and would like an example. Or are there an easier way than using keytool?

  • Mailer Daemon greeting failed

    - by Xelluloid
    I wrote a tool that sends automated mails to a couple of addresses. This worked for a couple of weeks. Now since yesterday I get Mailer-Daemon responses like this Hi. This is the qmail-send program at test.test2.net. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. testuser@domain.com: Connected to 123.456.789.10 but greeting failed. Remote host said: 554 foo.bar.com I'm not going to try again; this message has been in the queue too long. Does someone have an idea what I can do now?

  • From a quality perspective, what is better: Turning volume up in the software, in the OS, or on the speakers?

    - by Qqwy
    I kept thinking about this, and out of sheer curiosity, I decided to ask: If music isn't loud enough. How do I get the best quality?(Even if the difference is in fact so small it's neglectible) By making the music louder in my music player, game or other sound-producing software program. By raising the volume at the Operating System level (for instance, by clicking the 'speaker' icon on the windows bar and turning the volume up) By turning the volume up on the Amplifier or Speakers that are attached to your computer, and thus changing the volume on the 'hardware' Does programs vs OS matter? Does software vs. hardware matter? Thanks, Qqwy

  • How do I create a guest ftp user and give access to specific sub-folder with SSH?

    - by gourav
    I just got a virtual dedicated server at GoDaddy. I got the Simple Control Panel. There doesn't seem to be a way to create a guest ftp user through this control panel and I was told it must be created through SSH. I have a program called Putty which can log into the server via SSH. I'm familiar with logging in but does anyone know what the commands are to be used to create a guest ftp user and give them Read and Write access to a particular folder? Regards gourav

  • Prevent users from creating / copying / moving anything except .exe

    - by webnoob
    We have a program that compiles executables into a folder into c:\bin. Ideally I would like to share this folder so users can access the exe's within but stop them creating any other files in there. The reason for this is to stop users grabbing source code and putting it in a shared drive then taking it. We have a Domain Controller setup and all the users belong to a specific security group. Is there any way to achieve this? EDIT: TO clarify, I need to stop users from creating or moving files INTO the C:\bin folder which are not executables.

  • Android software for the system administrator on the move

    - by GruffTech
    My company has over service through Verizon, and AT&T Service in the area is "shoddy" at its best, so I haven't been able to join the "iPhone party" like so many of my fellow system administrators have been able to. That being said, this week finally a phone I like has hit Verizon, the HTC Incredible. (I've been waiting for the Desire or Nexus One, but after seeing spec sheets and reviews, HTC Incredible comes out ahead anyway). So (finally) I'm looking for Android Apps that are "gotta-haves" for system administrators. I've found the bottom three. If there are others you prefer over these let me know. RDP Program - RemoteRDP SSH Client - ConnectBot Nagios - NagMonDroid Reply with your favorite Android App and why!

  • This for array colllision function doesn't work with anything but first object in array

    - by Zee Bashew
    For some reason, this simple simple loop is totally broken. (characterSheet is my character Class, it's just a movieClip with some extra functionality) (hitBox, is basically a square movieclip) Anyway: every time hitBox make contact with a characterSheet in a different order than they were created: Nothing happens. The program only seems to be listening to collisions that are made with o2[0]. As soon as another hitBox is created, it pushes the last one out of o2[0] and the last one becomes totally useless. What's super weird is that I can hit characterSheets in any order I like.... public function collisions(o1:Array, o2:Array) { if((o1.lenght>=0)&&(o2.length>=0)){ for (var i = 0; i < o1.length; i++) { var ob1 = o1[i]; for (var f = 0; f < o1.length; f++) { var ob2 = o2[f]; if (ob1 is characterSheet) { if (ob2.hitTestObject(ob1)) { var right:Boolean = true; if (ob1.x < hitBox(ob2).origin.x) right = false; characterSheet(ob1).specialDamage(hitBox(ob2).damageType, hitBox(ob2).damage, right); }}}}}} Also it might be somewhat helpful to see the function for creating a new hitBox public function SpawnHitBox(targeted, following, atype, xoff, yoff, ... args) { var newHitBox = new hitBox(targeted, following, atype, xoff, yoff, args); badCollisionObjects.push(newHitBox); arraydictionary[newHitBox] = badCollisionObjects; addChild(newHitBox); }

  • Windows 8.1 & manual removal of "Sentinel Runtime Drivers"

    - by uos??
    I'm trying to install Windows 8.1 (basic upgrade from Windows 8). It is complaining of Sentinel Runtime Drivers incompatibility. I've looked for it in my Programs & Features list, but it's not there by that name nor SafeNet (as related by google search) nor do I see any obvious candidates for it having been bundled with another listed application. I tried the "Sentinel Runtime Driver Cleanup" program from the SafeNet website. It ran but was ineffective, even after a reboot. Do you recognize this "Sentinel Runtime Drivers"? I ran MalwareBytes too, just in case, but it found nothing.

  • winkey + arrow key doesn't move windows to 2nd monitor on linux

    - by Berry Tsakala
    in Windows, win+ <-- and win+ --> snap any window to the left/right side of a monitor, and if pressed again, snap the window to the other monitor, in multi-monitor environment. when a window is maximized, it will "restore" the window first, and at the next win+ <-- key the window will snap. this is very easy to use and remember. But on Linux a maximized window is not affected by win+ <-- , and the user must explicitly un-maximize it (win+down. the window is not moved to another monitor a side-snapped window cannot be resized - it behaves like a maximized window. is there another program that behaves like Windows, or I should write one by myself? (i'm using ubuntu/mint)

  • How to copy password from Mono-executed KeePass2 to xterm on Linux?

    - by Steve Emmerson
    I use KeePass2 to access username/password information in a Dropbox file. This allows convenient access from multiple devices. I can't seem to copy a password to the clipboard on my Linux 2.6.27.41-170.2.117.fc10.x86_64 system, however, in order to supply the password to a prompt in an xterm(1). I've tried both Ctrl+C/Ctrl+V and highlighting and mouse button 2 clicking. The KeePass2 program on the Linux system is executed by Mono. How can I copy the password to the xterm(1)? [Aside: I think we need a "KeePass" tag.] ADDENDUM: My mouse buttons were misconfigured: button 2 wasn't set to "copy". Sorry for the false alarm.

  • Firefox, Thunderbird, Safari - hangs up on start

    - by takeshin
    I have a strange problem on Windows Vista (Automatic updates). Long time ago I had installed Firefox, Thunderbird, Safari and Opera and they all worked well. Once upon a time, after Windows restart, Firefox, Thunderbird and Safari won't start. [Opera (USB) works fine]. When I start the browser, program name is listed on the processes list, but it is not activated, doesn't show any window. I tried crating new profiles with -ProfileManager, restarting Windows, reinstalling the browsers. I scanned the system for suspected programs and it looks clean. There is 45GB of free HDD space. WTF?

  • 3D physics engine for accurate collision handling on desktop/laptop computers (non-console)

    - by Georges Oates Larsen
    What are your suggestions for a physics engine that satisfies the following criteria? Capable of calculating collisions between multiple concave mesh-based colliders Handles many collisions going on at once (for instance one mesh being wedged between two others, which themselves may be wedged between two meshes) Does not allow for collider passthrough, even at high speeds. For instance, if I am applying force to a programmatically hinged object that makes it spin, I do not want it to pass through another rigidbody that it collides with while spinning. I have this problem using PhysX As implied before, reacts well to hinged objects, preferably has its own implementation of a hinge, but I am willing to program my own. The important part is that it has some sort of interface that guarantees accurate collision tracking even when dealing with these things Platform independent -- runs on mac as well as PC, also not tied down to specific graphics cards I think that's the best way to explain what I am looking for. Basically, I need SUPER reliable collisions. Something that can't be accomplished with a simple ray casting approach that sends a ray from the last position of the object to the current position (as this object may be potentially large and colliding with small objects via rotation) Bonus points for also including an OPEN SOURCE engine.

  • Dualboot Asus n56v (ubuntu / win 7 x64) - ubuntu doesn't detect partition table made by windows

    - by user76439
    I have an Asus n56v and I've got troubles installing Ubuntu 12.04 x64. I already have installed Windows 7 x64! The hard drive is: Hitachi HTS547575A9E384 My problem: The installation program doesn't recognize the already existing partitions and is offering only options where there are partitions. Can someone help me out? Is this an ACPI/IDE conflict, missing driver or conflict with Windows 7? (I'm not an expert on Linux, only working sometimes with it.) I now tried out some options concerning EFI with a GTP-table. Everything worked but I wasn't able to fix a dual boot (Windows boot loader) nor with GRUB2. The laptop is still having a BIOS, but is able to boot DVDs/CDs in EFI-mode. Now I try to avoid EFI and GTP using the old windows MBR style. I reinstalled Windows, so far no problem. When I want to try to install Ubuntu, it doesn't detect the already existing partition table. It is just showing me an empty space for the whole disk. Other threads like Ubuntu 12.04 does not see windows already install on my computer (dual installation) don't help me out. os-prober shows me a correct result. I don't know how to deal with gdisk as shown in Installer doesn't detect existing partition table/windows 7 partition. I have 750GB for the whole disk. I'm using: 90GB for Windows reserved partition + system partition, 500GB for data and the rest should be for SWAP and linux-system. How can I make Ubuntu detect the partition table?

  • How does datomic handle "corrections"?

    - by blueberryfields
    tl;dr Rich Hickey describes datomic as a system which implicitly deals with timestamps associated with data storage from my experience, data is often imperfectly stored in systems, and on many occasions needs to retroactively be corrected (ie, often the question of "was a True on Tuesday at 12:00pm?" will have an incorrect answer stored in the database) This seems like a spot where the abstractions behind datomic might break - do they? If they don't, how does the system handle such corrections? Rich Hickey, in several of his talks, justifies the creation of datomic, and explains its benefits. His work, if I understand correctly, is motivated by core the insight that humans, when speaking about data and facts, implicitly associate some of the related context into their work(a date-time). By pushing the work required to manage the implicit date-time component of context into the database, he's created a system which is both much easier to understand, and much easier to program. This turns out to be relevant to most database programmers in practice - his work saves everyone a lot of time managing complex, hard to produce/debug/fix, time queries. However, especially in large databases, data is often damaged/incorrect (maybe it was not input correctly, maybe it eroded over time, etc...). While most database updates are insertions of new facts, and should indeed be treated that way, a non-trivial subset of the work required to manage time-queries has to do with retroactive updates. I have yet to see any documentation which explains how such corrections, or retroactive updates, are handled by datomic; from my experience, they are a non-trivial (and incredibly difficult to deal with) subset of time-related data manipulation that database programmers are faced with. Does datomic gracefully handle such updates? If so, how?

  • Why is Windows Explorer not responding?

    - by William Barnes
    I am having the seemingy popular problem with Widows Explorer not responding. I have tried the AUTRUNS and turned off everything recommended. I have run SCANNOW 3 times and it comes back clean. When booting in safe mode it appears to work. I read someplace that the problem could be a service program, but can't remember where I read it or how to do it. Something about turning off all service programs and then turning them back on one at a time. The problem is I don't remember what it said to do. Any and all help is greatly appreciated. as an FYI here is my system stats Sorry I can't access that part of control panel right now because windows explore not responding. I have an HPdesk top with a AMD quad core processor 1.8GB 1.5TB sata drives (a 1TB and a 500GB) Nvidia 8400 graphics card a 2mb internet connetion wireless 2 DBD R?W drives.

  • txt file descriptor in lsof

    - by wfaulk
    In my experience, files that have the file descriptor of txt in lsof output are the executable file itself and shared objects. The lsof man page says that it means "program text (code and data)". While debugging a problem, I found a large number of data files (specifically, ElasticSearch database index files) that lsof reported as txt. These are definitely not executable files. The process was ElasticSearch itself, which is a java process, if that helps point someone in the right direction. I want to understand how this process is opening and using these files that gets it to be reported in this way. I'm trying to understand some memory utilization, and I suspect that these open files are related to some metrics I'm seeing in some way. The system is Solaris 10 x86.

  • Basic 3D Collision detection in XNA 4.0

    - by NDraskovic
    I have a problem with detecting collision between 2 models using BoundingSpheres in XNA 4.0. The code I'm using i very simple: private bool IsCollision(Model model1, Matrix world1, Model model2, Matrix world2) { for (int meshIndex1 = 0; meshIndex1 < model1.Meshes.Count; meshIndex1++) { BoundingSphere sphere1 = model1.Meshes[meshIndex1].BoundingSphere; sphere1 = sphere1.Transform(world1); for (int meshIndex2 = 0; meshIndex2 < model2.Meshes.Count; meshIndex2++) { BoundingSphere sphere2 = model2.Meshes[meshIndex2].BoundingSphere; sphere2 = sphere2.Transform(world2); if (sphere1.Intersects(sphere2)) return true; } } return false; } The problem I'm getting is that when I call this method from the Update method, the program behaves as if this method always returns true value (which of course is not correct). The code for calling is very simple (although this is only the test code): if (IsCollision(model1, worldModel1, model2, worldModel2)) { Window.Title = "Intersects"; } What is causing this?

  • Find computer names on a private network (with nmap?)

    On a LAN, I want to find out the names of all the connected computers using a cross-platform program, preferably nmap. I know I can do nmap -sn xxx.xxx.xxx.xxx/24 (where xxx.xxx.xxx.xxx is a local IP address) to find hosts which are up, but how do I find the computers' hostnames? Do they broadcast this in a way that I can find using nmap? UPDATE: It looks like Angry IP Scanner can do this. How does it do this? Can I replicate it with nmap?

  • Does anyone still use Iometer?

    - by Brian T Hannan
    "Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It is used as a benchmark and troubleshooting tool and is easily configured to replicate the behaviour of many popular applications." link text Does anyone still use this tool? It seems helpful, but I'm not sure if it's for the thing I am trying to work on. I am trying create a benchmark computer performance test that can be run before and after a Windows Optimization program does its stuff (ex: PC Optimizer Pro or CCleaner). I want to be able to make a quick statement like CCleaner makes the computer run 50% faster or something along those lines. Are there any newer tools like this one?
