• HELP! Free space not reclaimed after online resizing ext4 in Ubuntu 9.10

  - by TiansHUo

  My root partition was filling up, with only 500 mbs left, I wanted to resize my root partition from 20 Gb to 40Gb So I resized my partition by using these steps: Using Gparted to resize another partition to give space for the EXT4 Using fdisk, deleting the root partition (on /dev/sda2), and creating it again using the new size resize2fs /dev/sda2 Updating grub2 But now the problem is that although I can boot in my new partition and the new partition shows it is 40Gb, but the free size was still 500mb. So I booted from a LiveCD and checked with e2fsck -p /dev/sda2, it reported clean. So I added the -f flag (force check), still, the drive is full.

• 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.

• ASP.NET MVC 3 (C#) Software Architecture

  - by ryanzec

  I am starting on a relatively large and ambitious ASP.NET MVC 3 project and just thinking about the best way to organize my code. The project is basically going to be a general management system that will be capable of supporting any type management system whether it be a blogging system, cms, reservation system, wikis, forums, project management system, etc…, each of them being just a separate 'module'. You can read more about it on my blog posted here : http://www.ryanzec.com/index.php/blog/details/8 (forgive me, the style of the site kinda sucks). For those who don't want to read the long blog post the basic idea is that the core system itself is nothing more than a users system with an admin interface to manage the users system. Then you just add on module as you need them and the module I will be creating is a simple blog post to test it out before I move on to the big module which is a project management system. Now I am just trying to think of the best way to structure this so that it is easy for users to add in there own modules but easy for me to update to core system without worrying about the user modifying the core code. I think the ideal way would be to have a number of core projects that user is specifically told not to modify otherwise the system may become unstable and future updates would not work. When the user wants to add in there own modules, they would just add in a new project (or multiple projects). The thing is I am not sure that it is even possible to use multiple projects all with their own controllers, razor view template, css, javascript, etc... in one web application. Ideally each module would have some of it own razor view templates, css, javascript, image files and also need access to some of the core razor view templates, css, javascript, image files which would is in a separate project. It is possible to have 1 web application run off of controllers, razor view templates, css, javascript, image files that are store in multiple projects? Is there a better was to structure this to allow the user to easily add in module with having to modify the core code?

• Splitting a tetris game apart - where to put time-management?

  - by nightcracker

  I am creating a tetris game in C++ & SDL, and I'm trying to do it "good" by making it object-oriented and keeping scopes small. So far I have the following structure: A main with some lowlevel SDL set up and handling input A game class that keeps track of score and provides the interface for main (move block down, etc) A map class that keeps track of the current game field, which blocks are where. Used by the game class. A block class that consists of the current falling block, used by game. A renderer class abstracting low level SDL to a format where you render "tetris blocks". Used by map and block. Now I have a though time where to place the time-management of this game. For example, where should be decided when a block bumps the bottom of the screen how long it takes the current block locks in place and a new block spawns? I also have an other unrelated question, is there some place where you can find some standard data on tetris like standard score tables, rulesets, timings, etc?

• Syntax for piping varnish logs to rotatelogs

  - by jetboy

  Ubuntu 12.04 Server x64, Varnish 3.0.2 I'm trying to pipe varnishncsa's logs through Apache's rotatelogs, and running from the shell, things work fine: sudo varnishncsa -a -P /var/run/varnishncsa/varnishncsa.pid |/usr/sbin/rotatelogs /var/log/varnish/varnish.log.%Y%m%d%H 3600 creates a new logfile in /var/log/varnish, with rotation every hour (3600 seconds). However, I'm struggling to get things working the same way inside /etc/init.d/varnishncsa: PATH=/sbin:/bin:/usr/sbin:/usr/bin DAEMON=/usr/bin/$NAME PIDFILE=/var/run/$NAME/$NAME.pid LOGFILE=/var/log/varnish/varnishncsa.log USER=varnishlog DAEMON_OPTS="-a -P ${PIDFILE}" DAEMON_PIPE="|/usr/sbin/rotatelogs /var/log/varnish/varnish.log.%Y%m%d%H 3600" ... start_varnishncsa() { output=$(/bin/tempfile -s.varnish) log_daemon_msg "Starting $DESC" "$NAME" create_pid_directory if start-stop-daemon --start --verbose --pidfile ${PIDFILE} \ --chuid $USER --exec ${DAEMON} -- ${DAEMON_OPTS} \ > ${output} 2>&1; then log_end_msg 0 else log_end_msg 1 cat $output exit 1 fi rm $output } Where should I put DAEMON_PIPE in the above code? I've tried at the end of: if start-stop-daemon --start --verbose --pidfile ${PIDFILE} which is where additional command line parameters usually go, but it isn't creating a logfile.

• What kind of physics to choose for our arcade 3D MMO?

  - by Nick

  We're creating an action MMO using Three.js (WebGL) with an arcadish feel, and implementing physics for it has been a pain in the butt. Our game has a terrain where the character will walk on, and in the future 3D objects (a house, a tree, etc) that will have collisions. In terms of complexity, the physics engine should be like World of Warcraft. We don't need friction, bouncing behaviour or anything more complex like joints, etc. Just gravity. I have managed to implement terrain physics so far by casting a ray downwards, but it does not take into account possible 3D objects. Note that these 3D objects need to have convex collisions, so our artists create a 3D house and the player can walk inside but can't walk through the walls. How do I implement proper collision detection with 3D objects like in World of Warcraft? Do I need an advanced physics engine? I read about Physijs which looks cool, but I fear that it may be overkill to implement that for our game. Also, how does WoW do it? Do they have a separate raycasting system for the terrain? Or do they treat the terrain like any other convex mesh? A screenshot of our game so far:

• How can I configure Adobe Help so it doesn't chatter so much with Adobe's domain?

  - by Michael Prescott

  Adobe Help that came with Creative Suite 5 and/or Flash Builder Pro is constantly creating network traffic with an Adobe site, www.wip4.adobe.com In the Adobe Help application Preferences, I find that I can change the settings so that I must manually download updates, but apparently the application still likes to call home and chatter non-stop with www.wip4.adobe.com. I could use something like Little Snitch to block all this spyware-like behavior, but I'd really prefer to just change the application's behavior. Is there a hidden setting or configuration file to adjust this behavior to something more appropriate and polite?

• How to determine if a file has been backed up?

  - by Console

  I try to consolidate old drives to new ones of larger capacity. Sometimes files have been renamed, but are otherwise identical. Sometimes an old directory has just a few more files in it than a newer directory with the same name. Sometimes a file has the same name but the size differs. So I often find myself asking the question: Are there any files on this old drive or directory that I haven't already copied to the new drive? I just want to know that I have the files, I don't want to try and sync stuff automatically (Syncing tools tend to just sync, creating duplicate folder structures and other problems, so I prefer to do it by hand). Basically, if an old drive has a file called "foo.bar" ten directories deep, and my new big drive has an identical file called "oldstuff.zip" in the root, I just want a "yes you have it" or "no, unique files exist". Is there a free tool, a script or a quick and easy method (Mac/Unix or Windows) to get the answer?

• Launch apps or run commands on Windows via shortcuts

  - by Francisc

  Is it possible to register shortcuts on Windows 7 so that regardless where you are looking (Desktop, a folder etc) the shortcut gets "heard" and the appropriate action is performed. For example, creating a shortcut in the System32 folder which will work if you use Run with the shortcut's name, will not work if you set a key combination when focus is set on the Desktop for example. Is there a native way of registering top-level shortcuts or even an application for enabling this? Example of things I want keyboard shortcuts for: open a specific folder like %path% create a new .js file in the current folder launch an application eventually with its path set to the current location if the app supports this (e.g. command prompt) Thank you.

• Cleaning Up After Chrome

  - by Mark Treadwell

  I find Google Chrome, which I have no interest in, is continually getting installed on machines in my house, mostly due to Adobe Shockwave bringing it along as an install package. (Family members are agreeing to the download, not realizing the Chrome is getting dropped as well.) My major issue after uninstalling Chrome is that you can no longer click on links in Outlook emails. There is a lot on the web about this, and Google has not been proactive at fixing their uninstaller. I have now added a registry file to my Win64 systems to reset the problem registry keys and clear the error. This registry file is pretty simple. It merely resets HKEY_CURRENT_USER\Software\Classes\.htm, HKEY_CURRENT_USER\Software\Classes\.html, and HKEY_CURRENT_USER\Software\Classes\.shtml back to their default values of "htmlfile". Chrome takes over the handling of these file extensions because its default install is to make itself the default web browser. The Chrome uninstalled fails to clear/reset them. In troubleshooting this, I looked in my registry based on the web info on the Chrome uninstall problem. Since my system had never had Chrome installed, my registry did not have the problem keys. To troubleshoot, I installed (ugh!) and uninstalled Chrome. Sure enough, Chrome left the expected debris with a value string of "ChromeHTML.PR2EPLWMBQZK3BY7Z2BFBMFERU" or something similar. Resetting these values fixed the problem. I see that Chrome leaves quite a bit of debris behind in the registry. I guess it is creating the keys then leaving them behind, even though their presence (with bad data) subsequently affects operations.

• Windows XP: Consequences of setting a password for an account

  - by sleske

  I do not quite understand how Windows (specifically Windows XP) handles accounts with/without passwords. As far as I can see, on a fresh Windows XP install I have one default account which has admin rights does not have a password will auto-login (without password prompt) when the computer boots What happens if I set a password for this account? Will it still auto-login? Or will it always prompt for the PW? And generally, what consequences does it have if I set a password? I noted that Scheduled Tasks apparently cannot run under an account w/o password (creating a scheduled task will prompt for the account PW). Is there anything that will not work with a password set? Why is it even possible to have accounts without a password? I have some Unix/Linux background, but the concepts appear a little different under Windows.

• error 0x80070522. not able to create a file in c:\ directory

  - by Abbas

  Hello Everybody... "error 0x80070522. not able to create a file in c:\ directory" One of our customers has just found a problem when trying to create a file on the root of the C:\ Drive, on a Windows 7 Professional PC. I know they shouln't be keeping files here, but there is a valid reason in this case, so I've relaxed the security on the root of C:\ by giving the group 'users' modify permission. Before I relaxed the security, the user was receiving 'access denied', but now they are receiving the message: An unexpected error is keeping you from creating the file. If you continue to recieve this error, you can use the error code to search for help with this problem. Error 0x80070522: A required priviledge is not held by the client. Googling for this suggests that it is caused by UAC, but how can I get round this when the user doesn't have admin rights on their PC? So did you find a solution for this issue ?? Please its urgent to my accountant software..

• Create a tunnel to my dedicated windows server

  - by Mobiz

  I have a Win 2008 dedicated server. The remote access for MSSQL db is disabled. However I want to connect to it during development from my system. I need to create something like a tunnel from my lap so as to access it. I don't have static IP. Another reason for mentioning about creating tunnel is that my server IP has been whitelisted with other server. The data must originate from my dedicated server then only I can do the testing.

• How to execute a script while booting Linux from flashdrive?

  - by Usman Ajmal

  I know i can make my script run at boot time in runlevel 2 by putting it in /etc/init.d/ and creating a symbolic to it in /etc/rc2.d but thats when Linux is on hard drive. I want to run my script from a flashdrive such that when a user plug in a flashdrive and powers ON the machine, it may start booting from the OS in flash drive and eventually executing my script. How can I achieve such a functionality? I have tried burning OS to flashdrive but I never succeeded in booting OS from flashdrive.

• Joomla: Cross site link boxes

  - by Dean Smith

  I am currently evaluating Joomla for use on the the rebuild of our corporate website. One of the features our designs have is spaces for what we've been calling widgets. These widgets include common ones for each page, contact us boxes, section navigation, that all seem pretty easy to implement. The other widgets we would us to highlight specific pages within the site relevant to the one you are on, and are therefore different for each article. We've called these link widgets and these are a pretty common site on many websites. I'm honestly at a bit of a loss as to how to do this with Joomla. From a CMS perspective I'd like to allow users to just select which three link widgets they want when editing the article and have some way of creating the widgets within the CMS as well. Editing the link widget would allow setting a title, a bit of text and selecting the page that it links to. Am I going to be able to do this with Joomla, and if I can roughly how to I go about it ?

• ignore or override current document page formatting with predefined settings automatically libreoffice

  - by alex

  When opening a document made by someone else, I would like the margins to automatically be set to 0.4 cm, the page orientation to landscape and page size to A3. My dad gets emailed a spreadsheet weekly and he prints them off. To fit them onto one page he applies these settings, which is quite laborious. I thought that there must be a quicker way of doing this! I tried creating a new default template with these settings but this only works for a new blank document. I tried to create a style to quickly apply these settings but I realised these styles are document / template specific (?) and so don't appear when opening someone else's document. Anyone have any ideas how I can do this? Thanks =]

• Boot to VHD backup plan

  - by Josh Barker

  I have a machine that I just reinstalled Windows and all of my applications onto... what a chore that is. I want to totally and completely avoid this from now on by creating an image. My first thought was to see if it possible to copy a VHD file when you are booted into it since I am using Windows 7 Ultimate as boot-to-vhd (without a parent machine). Is this possible and if so, how could I accomplish this? Keep in mind, this is my personal machine and I'm trying to keep things inexpensive (a good script would work). Thanks, Josh

• What is the disadvantage of using abstract class as a database connectivity in zend framework 2 instead of service locator

  - by arslaan ejaz

  If I use database by creating adapter with drivers, initialize it in some abstract class and extend that abstract class to required model. Then use simple query statement. Like this: namespace My-Model\Model\DB; abstract class MysqliDB { protected $adapter; public function __construct(){ $this->adapter = new \Zend\Db\Adapter\Adapter(array( 'driver' => 'Mysqli', 'database' => 'my-database', 'username' => 'root', 'password' => '' )); } } And use abstract class of database like this in my models: class States extends DB\MysqliDB{ public function __construct(){ parent::__construct(); } protected $states = array(); public function select_all_states(){ $data = $this->adapter->query('select * from states'); foreach ($data->execute() as $row){ $this->states[] = $row; } return $this->states; } } I am new to zend framework, before i have experience of working in YII and Codeigniter. I like the object oriented in zend so i want to use it like this. And don't want to use it through service locater something like this: public function getServiceConfig(){ return array( 'factories' => array( 'addserver-mysqli' => new Model\MyAdapterFactory('addserver-mysqli'), 'loginDB' => function ($sm){ $adapter = $sm->get('addserver-mysqli'); return new LoginDB($adapter); } ) ); } In module. Am i Ok with this approach?

• How successful is GPL in reaching its goals?

  - by StasM

  There are, broadly, two types of FOSS licenses when it relates to commercial usage of the code - let's say the GPL-type and the BSD-type. The first is, broadly, restrictive about commercial usage (by usage I also mean modification and redistribution, as well as creating derived works, etc.) of the code under the license, and the second is much more permissive. As I understand, the idea behind GPL-type licenses is to encourage people to abandon the proprietary software model and instead convert to the FOSS code, and the license is the instrument to entice them to do so - i.e. "you can use this nice software, but only if you agree to come to our camp and play by our rules". What I want to ask is - was this strategy successful so far? I.e. are there any major achievements in the form of some big project going from closed to open because of GPL or some software being developed in the open only because GPL made it so? How big is the impact of this strategy - compared, say, to the world where everybody would have BSD-type licenses or release all open-source code under public domain? Note that I am not asking if FOSS model is successful - this is beyond question. What I am asking is if the specific way of enticing people to convert from proprietary to FOSS used by GPL-type and not used by BSD-type licenses was successful. I also don't ask about the merits of GPL itself as the license - just about the fact of its effectiveness.

• Outlook 2010 sharing calendars and updating

  - by Stef

  We recently purchased Outlook 2010 for our law firm. We have several secretaries that need to view all calendars and input information in each of them. We do not have Exchange. I did a test by creating a calendar on one computer and sharing it with another computer. On the second computer I created a calendar and shared it with the first computer. Everything seems to work, except when I put events on computer 1 calendar and look at computer 1 calendar on computer 2. I can not see anything. Any advice would help. Thanks

• PhysX Capsule Character Controller floating above ground

  - by Jannie

  I am using PhysX Version 3.0.2 in the simulation package I'm working on, and I've encountered some bizarre behavior with the capsule character controller. When I set the controller's height and radius to the appropriate values (r = 0.25, h = 1.86)it behaves correctly (moving along the ground, colliding with other objects, and so on) except that the capsule itself is floating above the ground. The actor will then bump his head when trying to get through a door, since the capsule is the correct height but also floating above the ground. This image should illustrate what I'm going on about: One can clearly see that the rest of the scene has their collision bodies wrapped correctly, it's just the capsule that's going wrong! The stop-gap I've implemented is creating a smaller capsule and giving it an offset, but I need to implement ray-picking for the controller next so the capsule has to surround the character model properly. Here's my character creation code (with height = 1.86f and radius = 0.25f): NxController* D3DPhysXManager::CreateCharacterController( std::string l_stdsControllerName, float l_fHeight, float l_fRadius, D3DXVECTOR3 l_v3Position ) { NxCapsuleControllerDesc l_CapsuleControllerDescription; l_CapsuleControllerDescription.height = l_fHeight; l_CapsuleControllerDescription.radius = l_fRadius; l_CapsuleControllerDescription.position.set( l_v3Position.x, l_v3Position.y, l_v3Position.z ); l_CapsuleControllerDescription.callback = &this->m_ControllerHitReport; NxController* l_pController = this->m_pControllerManager->createController( this->m_pScene, l_CapsuleControllerDescription ); this->m_pControllerMap.insert( l_ControllerValuePair( l_stdsControllerName, l_pController ) ); return l_pController; } Any help at all would be appreciated, I just can't figure this one out! P.S. I've found a couple of (rather old) threads describing the same issue, but it seems they couldn't find a solution either. Here are the links: http://forum-archive.developer.nvidia.com/index.php?showtopic=6409 http://forum-archive.developer.nvidia.com/index.php?showtopic=3272 http://www.ogre3d.org/addonforums/viewtopic.php?f=8&t=23003

• Determine process using a port, without sudo

  - by pat

  I'd like to find out which process (in particular, the process id) is using a given port. The one catch is, I don't want to use sudo, nor am I logged in as root. The processes I want this to work for are run by the same user that I want to find the process id - so I would have thought this was simple. Both lsof and netstat won't tell me the process id unless I run them using sudo - they will tell me that the port is being used though. As some extra context - I have various apps all connecting via SSH to a server I manage, and creating reverse port forwards. Once those are set up, my server does some processing using the forwarded port, and then the connection can be killed. If I can map specific ports (each app has their own) to processes, this is a simple script. Any suggestions? This is on an Ubuntu box, by the way - but I'm guessing any solution will be standard across most Linux distros.

• Issue with Visual C++ 2010 (Express) External Tools command

  Hi all, Normally we develop in VS 2005 Pro, but I wanted to give VS 2010 a spin. We have custom build tools based off of GNU make tools that are called when creating an executable. This is the error that I see whenever I call my external tool: ...\gnu\make.exe): *** couldn't commit memory for cygwin heap, Win32 error 487 The caveat is that it still works perfectly fine in VS2005, as well as being called straight from the command line. Also, my external tool is setup exactly the same as in VS 2005. Is there some setting somewhere that could cause this error to be thrown?

• How to make PDF pages with U3D images print properly?

  - by David Thornley

  I'm creating some PDF files that have three-dimensional images (U3D) in them. When I bring them up in Acrobat, everything is fine until I try to print the file. If I've viewed a page, it prints fine, showing the U3D image as I last saw it. If I haven't viewed a page yet, the printout is blank. (I can demonstrate this right from the Print dialog, by previewing pages.) The only reference I've seen to printing U3D is in the PDF Standard, which says, basically, that this should work. It recommends "PV" or "PO" for the A key in the 3D activation dictionary, and I'm using libharu which uses "PV".
