• Looking for a simple web interface with subversion support and ticket /issue tracker [closed]

  - by Stefan Andre Brannfjell

  I am working on a small project and we have a few programmers on the job. We are using subversion to commit updates and keep all developers up to date on their workstations. However, we have yet to find a suitable web interface to use for it. I have tried redmine, but that installation progress was extremely bothersome and advanced. Once I got it to work I found out that it was slow and did not meet my expectations. As well as it seems a bit complex for our needs. I would prefer to find a solution that supports lighttpd web server, however that seem to be very hard to come by, those I have found seem to only have apache support. Functionality i wish for the website: - login to an svn account - view svn logs - view & create issues, todo list etc - view svn difference Do you have any open source recommendations that I can try out? I will appreciate any kind of reply. :) Edit: I wish to host the website on our own servers.

• Android threads trouble wrapping my head around design

  - by semajhan

  I am having trouble wrapping my head around game design. On the android platform, I have an activity and set its content view with a custom surface view. The custom surface view acts as my panel and I create instances of all classes and do all the drawing and calculation in there. Question: Should I instead create the instances of other classes in my activity? Now I create a custom thread class that handles the game loop. Question: How do I use this one class in all my activities? Or do I have to create a separate thread each time? In my previous game, I had multiple levels that had to create an instance of the thread class and in the thread class I had to set constructor methods for each separate level and in the loop use a switch statement to check which level it needs to render and update. Sorry if that sounds confusing. I just want to know if the method I am using is inefficient (which it probably is) and how to go about designing it the correct way. I have read many tutorials out there and I am still having lots of trouble with this particular topic. Maybe a link to a some tutorials that explain this? Thanks.

• Looking Under the Hood of ...

  - by rickramsey

  copyright 2012 Rob Lang Fair is fair. Our last post featured a conversation with the beautiful and talented Eva Mendez, so today we're featuring something for those of you who prefer the other gender of our fair species. This dude has quite the hardware challenge ahead of him. He hasn't begun to find out what's really under that hood. Life is much easier for you and me, thanks to Jeff Wright and Suzanne Zorn. They wrote a wicked cool article about Oracle VM Server for SPARC. Here's a little bit about it... Looking Under the Hood of Networking in Oracle VM Server for x86 Oracle VM Server for SPARC lets you create logical networks out of physical Ethernet ports, bonded ports, VLAN segments, virtual MAC addresses (VNICs), and network channels. You can then assign channels (or "roles") to each logical network so that it handles the type of traffic you want it to. Greg King explains how you go about doing this, and how Oracle VM Server for SPARC implements the network infrastructure you configured. He also describes how the VM interacts with paravirtualized guest operating systems, hardware virtualized operating systems, and VLANs. Finally, he provides an example that shows you how it all looks from the VM Manager view, the logical view, and the command line view of Oracle VM Server for x86. More Resources for Oracle VM Server for x86 If you liked Greg and Suzanne's paper, you can ...

• Find files containing a string on the whole filesystem

  - by Fabio

  I need to find all the instances of a given string in the whole filesystem, because I don't remember in which configuration files, script or any other programs I put it and I need to update that string with a new one. I tried with the following command `grep -nr 'needle' / --exclude-dir=.svn | mail [email protected] -s 'References on xxx' If I run this command on a small directory it gives me the output I need in the form /path1/:nn:line containing needle /path2/:nn:line containing needle where /path1 is the full path of the file, nn is the row containing the needle and last field is the content of the line. However when I run the command on the root directory the grep process hang after a while. I run this script about 8 hours ago and even on a small filesystem (less than 5GB) it doesn't end and if I run top or ps the process seems sleeping root 24909 0.0 0.1 3772 1520 pts/1 S+ Feb10 0:15 grep -nr needle / --exclude-dir=.svn Why it doesn't end? Is there any better way to do this (it's a one time job, I don't need to execute this more than once) Thanks.

• Suppressing / Accepting warning windows automatically in commands executed through batch file

  - by David Somach

  I am automating the uninstall of IE9 through executing the command in these instructions inside a batch file: http://answers.microsoft.com/en-us/ie/forum/ie9-windows_7/how-to-uninstall-ie9-beta-64-bit-it-is-not-in-the/863d8f3d-c4ab-43e6-9d57-e163ea3baddd The instructions say to run the command twice. The first time the command runs, I get the following error window (3 times): "Windows Package Manager Operation failed with 0x80070005 Access id denied." I click OK for each of these windows, and the rest of the script runs fine and IE8 is usable after restart. Is there a way to suppress these windows? I want this to be fully automated and these windows block the script until the user presses "OK".

• Editing .bash_profile file not taking effect

  - by Sandeepan Nath

  I need to put export PATH=$PATH:/opt/lampp/bin to my ~/.bash_profile file so that mysql from command line works on my system. Please check mysql command line not working for further details on that. I am working on a fedora system and logged in as root user. If I run locate .bash_profile then I get these:- /etc/skel/.bash_profile /home/sam/.bash_profile /home/sohil/.bash_profile /home/windows/.bash_profile /root/.bash_profile So, I modified the /root/.bash_profile file like this:- from PATH=$PATH:$HOME/bin export PATH to PATH=$PATH:/opt/lampp/bin export PATH But, still the change is not taking effect - Opening a new console and running mysql again says bash: mysql: command not found. However running export PATH=$PATH:/opt/lampp/bin in console makes it work for that session. So, I am doing something wrong with the .bash_profile file. May be editing incorrect one or doing the edit incorrectly.

  My debian 5 vps is suffering from random shutdowns.

• Convert svn repository to hg - authentication fails

  - by Kim L

  I'm trying to convert an existing svn repository to a mercurial repo with the following command hg convert <repository> <folder> My problem is that the svn repository's authentication is done with p12 certificates. I'm a bit lost on how to configure the certificate for the hg client so that I can pull the svn repo and convert it. Currently, if I try to run the above command, I get initializing destination hg-client repository abort: error: _ssl.c:480: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure In other words, it cannot find the required certificate. The question is, how do I configure my hg client so that it can use my certificate? I'm using the command line hg client on linux.

• How can I perform a controlled shutdown of a virtualbox guest using VBoxManage?

  - by Bryan

  I'm currently testing Ubuntu 10.04, and have install the VirtualBox software. I have also installed Ubuntu 10.04 as a VirtualBox guest running on the host system. I've installed the VirtualBox Utils into the guest OS, as follows: sudo apt-get install virtualbox-ose-guest-utils What I want to be able to do is to initiate a controlled shutdown of the guest, from the host system using the VBoxManage command. I first tried this command: VBoxManage controlvm guest poweroff which worked, but didn't initiate a controlled shutdown, it effectively pulls the plug on the guest. I've since found that this command should do the trick: VBoxManage controlvm guest acpipowerbutton but this doesn't appear to do anything. Can anyone tell me what I'm doing wrong? p.s. I don't want to use SSH & Certificates to do this, as I'm also going to be running Windows guests, and I want the solution to work for all guests.

• Incomplete mesh using DrawIndexedPrimitives after rotating mesh

  - by user1278255

  Through help on this site I was able to draw the triangles of an unrotated, nonscaled nontransformed mesh created in Blender and exported to OBJ, accurately imported through Assimp and rendered in XNA Graphics. However after applying rotation on a single axis in Blender(Z) and adding materials(I wanted to test loading of materials through Assimp) the same mesh appears incomplete. Is something wrong with my view matrix or is it something else? This is what the unrotated mesh looks like: http://www.4shared.com/photo/qXNUSvxtba/okcube.html Here is the rotated mesh: http://www.4shared.com/photo/HAys2rWvba/badcube.html Camera, View and Projection are defined as follows: cameraPos = new Vector3(0, 5, 9); viewMatrix = Matrix.CreateLookAt(cameraPos, new Vector3(0, 0, 1), new Vector3(0, 1, 0)); projectionMatrix = Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver4, device.Viewport.AspectRatio, 1.0f, 200.0f); Rendering is done through this code: device.Clear(ClearOptions.Target | ClearOptions.DepthBuffer, Color.DarkSlateBlue, 1.0f, 0); effect = new BasicEffect(GraphicsDevice); effect.VertexColorEnabled = true; effect.View = viewMatrix; effect.Projection = projectionMatrix; effect.World = Matrix.Identity; foreach (EffectPass pass in effect.CurrentTechnique.Passes) { pass.Apply(); device.SetVertexBuffer(vertexBuffer); device.Indices = indexBuffer; device.DrawIndexedPrimitives(Microsoft.Xna.Framework.Graphics.PrimitiveType.TriangleList, 0, 0, oScene.Meshes[0].VertexCount, 0, mMesh.FaceCount); } base.Draw(gameTime);

• Mysql-proxy compile in CentOS

  Hey, While trying to compile Mysql-Poxy i get the following error. By the instructions here Libtool library used but `LIBTOOL' is undefined The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL' to `configure.in' and run `aclocal' and `autoconf' again. If `AC_PROG_LIBTOOL' is in `configure.in', make sure its definition is in aclocal's search path Libtool installed from source.

• Stuck With grub rescue> console

  - by rej santos

  Here is the background of my issue: I just recently installed the latest version of Ubuntu along side with Windows 8 Enterprise. However upon checking the disk size, it seems that some of the portions of the hd memory were gone so I decided to check the disk partition and have seen that is was being used by another file system. Thinking that the Ubuntu takes it boots stuff from my drive C: , I deleted that partition and formated so I can use it to store some movies, music etc. Now, as I switch on my machine, I am stucked with: error: unknown filesystem grub rescue> I googled a lot and saw the following command which seems no to me like sudo, chainloader etc, all of these command only returns unknown command in the console. What I just wanted is to boot from my Windows 8 OS. Just to add, I can't open the BIOS menu so I could choose what media to boot. As I open my machine it automatically takes me to grub rescue console. Here are the thing I already have: Ubuntu Installation Disk Windows 8 System repair Disk I just don't know how to boot into these things. Let me know what to do.

• Game Center Leaderboard not dismissing

  I was implementing Game Center into my app and all was going well except for the leaderboard done button not dismissing the leaderboard even with gameCenterControllerDidFinish added in. I call up the leaderboard with the touch of a button in the .m file as so: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInNode:self]; SKNode *node = [self nodeAtPoint:location]; if ([node.name isEqualToString:@"rankButton"]) { [self runAction:[SKAction playSoundFileNamed:@"fishtran.m4a" waitForCompletion: NO]]; GKGameCenterViewController *gameCenterController = [[GKGameCenterViewController alloc] init]; if (gameCenterController != nil) { gameCenterController.viewState = GKGameCenterViewControllerStateAchievements; UIViewController *vc = self.view.window.rootViewController; [vc presentViewController: gameCenterController animated: YES completion:nil]; } } else if ([node.name isEqualToString:@"Leaderboard"]) { GKGameCenterViewController *gameCenterController = [[GKGameCenterViewController alloc] init]; if (gameCenterController != nil) { gameCenterController.viewState = GKGameCenterViewControllerStateLeaderboards; UIViewController *vc = self.view.window.rootViewController; [vc presentViewController: gameCenterController animated: YES completion:nil]; } } ... and then I added thegameCenterControllerDidFinish immediately after as so: - (void)gameCenterControllerDidFinish:(GKGameCenterViewController*)gameCenterController { UIViewController *vc = self.view.window.rootViewController; [vc dismissViewControllerAnimated:YES completion:nil]; } and the done button still doesn't work and i haven't been able to find any solutions. And yes, I do have GKGameCenterControllerDelegate in my .h file. Any help would be greatly appreciated, Thanks!

• How can i use my local mysqldump through ssh tunnel

  - by Matthias Kleine

  I would like to dump a mysql-database with mysqldump. But: This command isn't installed on the remote server. It is possible to use my local mysqldump command, to connect via an ssh tunnel to achieve this? I found several solutions, but each one required the mysqldump command directly on the server. When I use Sequel Pro (an Mac OS X App), I can perform an export via an SSH tunnel. But this is not the fastest solution and cannot be used on a unix server...

• nVidia Settings: Overriding anti-aliasing causes delay

  - by Kalle Elmér

  I'm using Google Sketchup on ubuntu 12.04 with Wine 1.4. It works flawlessly out of the box, but anti-aliasing is causing some problems. I can override anti-aliasing settings using the nVidia X Server Settings utility, which results in a great-looking image. However, the view doesn't seem to update properly. It's a bit hard to explain, but if I do something (e.g. zooming) the changes won't appear in the view until I take another action. in other words, there seems to be a delay of one "action". Take this example. The mouse wheel is moved one notch to zoom in one step. Nothing happens. An object is selected by clicking. The new zoom is rendered but the selection box doesn't appear. An empty area is clicked. The selection box appears. Is there something that I can do to solve the problem? Could I force the GPU to redraw that view with a certain interval, or is there some other solution? I really like anti-aliasing, but it's hard to use when drawing stuff.

• Can't star SSH on Ubuntu 12.10 AWS EC2

  - by Conor H

  So i've just started playing around with Ubuntu on Amazon EC2. I've just issued the following command to restart ssh but it has now "killed" ssh. sudo /etc/init.d/ssh restart I can't seem to ssh to this instance anymore. Putty just gives me "connection refused". NOTE: In this case I just restarted SSH to see the result. I didn't change any settings. This was to confirm that it was the restart command was the problem and not any configs I made. What is the correct way to restart SSH? P.S. That usually works on other Ubuntu boxes. Thanks. EDIT: It is also worth noting that when I ran that command I was taken straight back to a prompt. I didn't get any output on the console.

• How to make a btrfs snapshot?

  - by MountainX

  My /home partition consists of an entire physical disk. It is formatted as btrfs. I want to snapshot it. I'm confused regarding subvolume naming, in particular. I am aware that there are similar questions, but each similar question seems to be asking something different from what I'm asking (and they are older, which means probably outdated, given the rapid development of btrfs). For example, the answer to this question is apparently not the answer to my question because my /home partition is a separate volume and the man page for btrfs shows a different command for creating snapshots now. another similar problem, no solid solution. someone else as confused as me on the naming issues My question: Starting simple: is this the correct command to take a simple snapshot of my home partition? btrfs subvolume snapshot /home/@home /home/@home_snapshot_20120421 I got really brave and tested it and it does not work. The error is error accessing /home/@home. As shown below, @home is listed. I'm obviously confused on subvolume names. Do I need to use them in creating snapshots? Some examples show taking snapshots of home using /home as the source parameter, but based on examples of root volumes, it seems to me that I need to use /home/@home. Would this command work? And if not, why? btrfs subvolume snapshot /home /home/@home_snapshot_20120421 Is the @ just a naming convention? Is it meaningful at all? Here's some output that may be relevant: btrfs subvolume list /home ID 256 top level 5 path @home I'm not sure what that means, exactly. When I try btrfs device scan it gives an error (e.g. unable to scan the device /dev/sda1). My file system doesn't have any errors. Everything is fine.

• Using a script that uses Duplicity + S3 excluding large files

• REST Service and CQRS

  - by Paul Wade

  I am struggling with architecture on a new project. I am using the following patterns/technology. CQRS - anything going in goes through a command REST - using WebAPI MVC - asp.net mvc Angular - building a spa nhibernate I belive this provides some great separation and should help keep a very complex domain from growing into a giant set of services that mix queries with other business logic. The REST services have become non restful. They are putting methods in rest that are "SearchByDate", "SearchByItem" etc. Service Methods that execute commands are called with a "web" model class, a new command is built in the service and executed, I feel like there is a lot of extra code. I expected this to be much different but I wasn't around to keep things on track. Finally my questions are this... I would have liked to see PUT Person (CreatePersonCommand) but then I realized that isn't restful either is it? the put should be a person entity not a command. Can I make CQRS and REST service work together or am I going about this all wrong? How do I handle service methods that don't fit into a REST model. I am not performing CRUD on the object but rather executing some business logic. I.E. I don't want the UI to be responsible for how a shipment is "unshipped" I want the service layer to worry about that.

• MVC + 3 tier; where ViewModels come into play?

  - by mikhairu

  I'm designing a 3-tiered application using ASP.NET MVC 4. I used the following resources as a reference. CodeProject: MVC + N-tier + Entity Framework Separating data access in ASP.NET MVC I have the following desingn so far. Presentation Layer (PL) (main MVC project, where M of MVC was moved to Data Access Layer): MyProjectName.Main Views/ Controllers/ ... Business Logic Layer (BLL): MyProjectName.BLL ViewModels/ ProjectServices/ ... Data Access Layer (DAL): MyProjectName.DAL Models/ Repositories.EF/ Repositories.Dapper/ ... Now, PL references BLL and BLL references DAL. This way lower layer does not depend on the one above it. In this design PL invokes a service of the BLL. PL can pass a View Model to BLL and BLL can pass a View Model back to PL. Also, BLL invokes DAL layer and DAL layer can return a Model back to BLL. BLL can in turn build a View Model and return it to PL. Up to now this pattern was working for me. However, I've ran into a problem where some of my ViewModels require joins on several entities. In the plain MVC approach, in the controller I used a LINQ query to do joins and then select new MyViewModel(){ ... }. But now, in the DAL I do not have access to where ViewModels are defined (in the BLL). This means I cannot do joins in DAL and return it to BLL. It seems I have to do separate queries in DAL (instead of joins in one query) and BLL would then use the result of these to build a ViewModel. This is very inconvenient, but I don't think I should be exposing DAL to ViewModels. Any ideas how I can solve this dilemma? Thanks.

• Creating a chain of certificates

  - by StackedCrooked

  This question is a follow up to my previous question, which was, in retrospect, not completely answered: http://superuser.com/questions/126121/how-to-create-my-own-certificate-chain. I'll represent my certificate chain like this: ROOT - A - B - C - ... I am now able to create the ROOT and A certificates, but I didn't succeed in continueing the chain. My command for creating the root certificate is: openssl req -new -newkey rsa:1024 -nodes -out ca.csr -keyout ca.key openssl x509 -trustout -signkey ca.key -days 365 -req -in ca.csr -out ca.pem Certificate A: openssl genrsa -out client.key 1024 openssl req -new -key client.key -out client.csr openssl ca -in client.csr -out client.cer This command depends on the root certificate implicitly using the data found in the openssl config file. Certificate B will only rely on A, so the previous command won't work here. How can I complete the chain?

• Can't Start ISC DHCP IPv6 Server

  Trying to enable the ISC DHCP server for just IPv6 on Ubuntu 12.04 LTS. I have downloaded and installed the DHCP server via the following command: $ sudo apt-get install isc-dhcp-server Then I have followed the instructions in the following resources, Ubuntu Wiki DHCPv6, SixXS - Configuring ISC DHCPv6 Server and Linux IPv6 HOWTO - Configuration of the ISC DHCP server for IPv6 . So from review all those resources it seems like I need to: set a static IPv6 address for the Interface I want to run the DHCPv6 server from that is part of the IPv6 network subnet outside the DHCP range. Edit the /etc/dhcp/dhcpd6.conf file to configure the DHCPv6 range etc. Create the /var/lib/dhcp/dhcpd6.leases Manually start the DHCPv6 server. Setting the Static IP for eth0 $ sudo ifconfig eth0 inet6 add 2001:db8:0:1::128/64 My dhcpd6.conf default-lease-time 600; max-lease-time 7200; log-facility local7; subnet6 2001:db8:0:1::/64 { #Range for clients range6 2001:db8:0:1::129 2001:db8:0:1::254; } Created the dhcpd6.leases file As indicated in the dhcpd.leases man page. $ touch /var/lib/dhcp/dhcpd6.leases #Tried with sudo as well Manually starting the DHCPv6 server.

• Running multiple box2D world objects on a server

  - by CharbelAbdo

  I'm creating a multiplayer game using LibGdx (with Box2d) and Kryonet. Since this is the first time I work on multiplayer games, I read a bit about server - client implementations, and it turns out that the server should handle important tasks like collision detection, hits, characters dying etc... Based on some articles (like the excellent Gabriel Gambetta Fast paced multiplayer series), I also know that the client should work in parallel to avoid the lag while the server responds to commands. Physics wise, each game will have 2 players, and any projectiles fired. What I'm thinking of doing is the following: Create a physics world on the client When the game is signaled to start, I create the same physics world on the server (without any rendering obviously). Whenever the player issues a command (move or fire), I send the command to the server and immediately start processing it on the client. When the server receives the command, it applies it on the server's world (set velocity etc...) Each 100ms, the server sends the new state to the client which corrects what was calculated locally. Any critical action (hit, death, level up) is calculated only on the server and sent to the client. Essentially, I would have a Box2d World object running on the server for each game in progress, in sync with the worlds running on the clients. The alternative would be to do my own calculations on the server instead of relying on Box2D to do them for me, but I'm trying to avoid that. My question is: Is it wise to have, for example, 1000 instances of the World object running and executing steps on the server? Tomcat used around 750 MBytes of memory when trying it without any object added to the world. Anybody tried that before? If not, is there any alternative? Google did not help me, are there any guidelines to use when you want to have physics on both the client and the server? Thanks for any help.

• Wheel rotation, to change velocity of vehicle

  - by Lewis

  I update the velocity of my vehicle like so: [v setVelocity: ((2 * 3.14 * 100 * (wheel.getRotationValue / 360) / 30)) * gameSpeed]; // update on 60 fps this gets velocity on all frames divide by 60 for 1 frame. This is done in my update method in my world class. Now wheel.getRotationValue returns the rotation value which is worked out like this: - (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; if (CGRectContainsPoint(wheel.boundingBox, location)) { CGPoint firstLocation = [touch previousLocationInView:[touch view]]; CGPoint location = [touch locationInView:[touch view]]; CGPoint touchingPoint = [[CCDirector sharedDirector] convertToGL:location]; CGPoint firstTouchingPoint = [[CCDirector sharedDirector] convertToGL:firstLocation]; CGPoint firstVector = ccpSub(firstTouchingPoint, wheel.position); CGFloat firstRotateAngle = -ccpToAngle(firstVector); CGFloat previousTouch = CC_RADIANS_TO_DEGREES(firstRotateAngle); CGPoint vector = ccpSub(touchingPoint, wheel.position); CGFloat rotateAngle = -ccpToAngle(vector); CGFloat currentTouch = CC_RADIANS_TO_DEGREES(rotateAngle); float limit = 0.5; rotationValue += (currentTouch - previousTouch) * limit; } touching = YES; } Say I steer the vehicle to the far right of the screen, and want to move it to the far left, It wont start moving to the left of the screen until the rotationValue is past 0 degrees again (the wheel is in its center posistion) and is dragged past this value. Is there anyway to change the code I have above, so that movement on the wheel is recognised instantly and updates the velocity of v instantly too?
