• keep getting added to hosts.deny + iptables

  - by Sc0rian

  I am confused to why this has started to happen. On my local network, if I click 10-20 apache/http links my server will decide to add me hosts.deny file and block me on iptables. Its not just apache, it seems to happen with any kinda of traffic, that comes in on a flood method. Like I use subsonic, if I change tracks 10-20 times, it will do it. I would assume I have some sort of firewall which is sitting on the server which is doing this. However I do not have fail2ban or any denyhosts in /var/lib. I cannot work out why I keep getting added to hosts.deny/iptables. Thanks

• Existing laravel 4 project gives 404 in browser

  - by Richard A

  I'm trying to set up a development environment on a virtual machine running Ubuntu 14.04 LTS using Nginx and HHVM. To do this, I followed the tutorial here. This goes well with a new installation of Laravel. But when I import an existing Laravel 4 project and try to open that on my actual machine (which will serve as the client running Windows 7), I'm getting a 404 File Not Found error on the screen while connecting to http://sav.savrichard.dev. I did add this to the hosts file with the correct IP Address. The virtual machine is receiving the request and responds with a 404 error. How do I solve this error? I'm pretty new to Ubuntu so I'm not exactly sure what's wrong. The project is located at /var/www/sav.savrichard.net The server configuration is as follow: server { listen 80 default_server; root /var/www/sav.savrichard.net/public; index index.html index.htm index.php; server_name sav.savrichard.dev; access_log /var/log/nginx/localhost.sav.savrichard.dev-access.log; error_log /var/log/nginx/localhost.sav.savrichard.dev-error.log error; charset utf-8; location / { try_files \$uri \$uri/ /index.php?\$query_string; } location = /favicon.ico { log_not_found off; access_log off; } location = /robots.txt { log_not_found off; access_log off; } error_page 404 /index.php; include hhvm.conf; # Deny .htaccess file access location ~ /\.ht { deny all; } } And the hhvm.conf file is: location ~ \.(hh|php)$ { fastcgi_keep_conn on; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; }

• What program has this icon?

  - by Andrew M

  I noticed a screenshot that included this icon in the sidebar, does anyone know what it's from? It looks cool! Looks vaguely reminiscient of Chrome but different enough that it could be a coincidence. I've tried putting it into a google image search but without any luck. Original source was this Ubuntu help page on unity launchers. which includes the original, larger screenshot. For context, it's not important, I'm just curious.

• Xubuntu 14.04, Power Manager, Screensaver

  - by Bathynomus

  When my computer is inactive, I keep getting a black screen and the screen goes into locked mode asking for a password, even though in Power Manager I have "Never" set for actions and monitor and Extended "Lock Screen" is unchecked. I don't see a screensaver, but perhaps that is the issue? Is anyone else experiencing this? Is this a bug? Is there a temporary workaround? I did not see this issue in 12.xx, 13.xx.

• Ubuntu won't appear on laptop startup

  - by Jade

  I've recently installed Ubuntu along with Windows Vista. So normally when the laptop is starting up it shows two options whether I want to log on Windows or Ubuntu. One day I shut down the laptop and I open it the next and it just logs onto Windows automatically without giving me the option to choose. I go to check if Ubuntu was un-installed or something, but it was still there and everything, but I can't open it. I don't know if there's any additional info I should add because I'm not very good with computers, and I don't want to re-install it because I have my stuff on it so I'd lose it, and I'm having trouble backing it up. Any suggestions?

• How to build a list from Postfix maillog

  - by dstonek

  I want to build a list from maillog, maillog.x containing something like Date, Sender's email, Recipient's Email and subject of the message filtering output emails and output domain. I've read about importing from spreadsheet program a cvs file. The issue is I have to add field separators in log file. I couldn't find how to customize that. How can I do that, the list and the separator? This is an example of sending mail log Jun 11 15:24:58 host postfix/cleanup[19060]: F41C660D98A0: warning: header Subject: TESTING SUBJECT from unknown[XXX.XXX.XXX.XXX]; [email protected] [email protected] proto=ESMTP helo=<[192.168.1.91] Jun 11 15:25:01 host postfix/smtp[19062]: F41C660D98A0: to=, relay=mx-rl.com[xxx.xxx.xxx.xxx]:25, delay=3.4, delays=0.66/0.01/0.86/1.9, dsn=2.0.0, status=sent (250 <538E30D9000A1DD8 Mail accepted) The list would contain the three bold fields filtering by to = [email protected]

• Kloxo - Use third party nameserver

  - by LePhleg

  Here's my case: I got my domain from a registrar. I got my VPS up from a provider who also offers free DNS hosting, on their own server (separately from my VPS, IP:111.111.111.111). So I got these third-party nameservers, lets name them: ns1.provider.com ns2.provider.com and pointed my domain registrar to them. I let it propagate for 24 hours so I believe its ok. (if I ping my domain I get the IP for these nameservers - 111.111.111.111) Afterwards I headed to my providers cPanel (the one they gave me for the DNS hosting service) and changed the default A Record IP from 111.111.111.111 to the IP associated with my VPS (IP:222.222.222.222). The last step, as I see it, is to configure my VPS via Kloxo panel and add the domain. Can someone guide me how can I achieve that? Is it just enough to create a new DNS Template and add as Primary DNS "ns1.provider.com" and Secondary DNS "ns2.provider.com"? Every tutorial I found is using Kloxo to create local nameservers on the same VPS which is something I want to avoid to save resources..

• Best way to redirect users back to the pretty URL who land on the _escaped_fragment_ one?

  - by Ryan

  I am working on an AJAX site and have successfully implemented Google's AJAX recommendation by creating _escape_fragment_ versions of each page for it to index. Thus each page has 2 URLs: pretty: example.com#!blog ugly: example.com?_escaped_fragment_=blog However, I have noticed in my analytics that some users are arriving on the site via the "ugly" URL and am looking for a clean way to redirect them to the pretty URL without impacting Google's ability to index the site. I have considered using a 301 redirect in the head but fear that Googlebot might try to follow it and end up in an endless loop. I have also considered using a JavaScript redirect that Googlebot wouldn't execute but fear that Google may interpret this as cloaking and penalize the website. Is there a good, clean, acceptable way to redirect real users away from the ugly URL if for some reason or another they end up arriving at the site that way?

• Tracking multiple subdomains and domains going to the same site, separately in Google Analytics

  - by miles

  I have a new site that has multiple top-level domains and subdomains all going to it: www.domain.com, campaign.domain.com, chicago.domain.com, domain2.com - all go to the same site/site directory. Right now I have one Google Analytics account profile set up for it, but I want to be able to track the traffic that is hitting those different URLs separately. The domains are being routed on the server-side (not .htaccess). How can I do this in Google Analytics? Do I need to create filters? Or create different profiles for each domain?

• Without using a pre-built physics engine, how can I implement 3-D collision detection from scratch?

  - by Andy Harglesis

  I want to tackle some basic 3-D collision detection and was wondering how engines handle this and give you a pretty interface and make it so easy ... I want to do it all myself, however. 2-D collision detection is extremely simple and can be done multiple ways that even beginner programmers could think up: 1.When the pixels touch; 2.when a rectangle range is exceeded; 3.when a pixel object is detected near another one in a pixel-based rendering engine. But 3-D is different with one dimension, but complex in many more so ... what are the general, basic understanding/examples on how 3-D collision detection can be implemented? Think two shaded, OpenGL cubes that are moved next to each other with a simple OpenGL rendering context and keyboard events.

• Splitting Pygame functionality between classes or modules?

  - by sec_goat

  I am attempting to make my pygame application more modular so that different functionalities are split up into different classes and modules. I am having some trouble getting pygame to allow me to draw or load images in secondary classes when the display has been set and pygame.init() has been done in my main class. I have typically used C# and XNA to accomplish this sort of behavior, but this time I need to use python. How do I init pygame in class1, then create an instance of class2 which loads and converts() images. I have tried pygame.init() in class 2 but then it tells me no display mode has been set, when it has been set in class1. I am under the impression i do not wnat to create multiple pygame.displays as that gets problematic I am probably missing something pythonic and simple but I am not sure what. How do I create a Display class, init python and then have other modules do my work like loading images, fonts etc.? here is the simplest version of what I am doing: class1: def __init__(self): self.screen = pygame.display.set_mode((600,400)) self.imageLoader = class2() class2: def __init__(self): self.images = ['list of images'] def load_images(): self.images = os.listdir('./images/') #get all images in the images directory for img in self.images: #read all images in the directory and load them into pygame new_img = pygame.image.load(os.path.join('images', img)).convert() scale_img = pygame.transform.scale(new_img, (pygame.display.Info().current_w, pygame.display.Info().current_h)) self.images.append(scale_img) if __name__ == "__main__": c1 = class1() c1.imageLoader.load_images() Of course when it tries to load an convert the images it tells me pygame has not been initialized, so i throw in a pygame.init() in class2 ( i have heard it is safe to init multiple times) and then the error goes to pygame.error: No video mode has been set

• Performance due to entity update

  - by Rizzo

  I always think about 2 ways to code the global Step() function, both with pros and cons. Please note that AIStep is just to provide another more step for whoever who wants it. // Approach 1 step foreach( entity in entities ) { entity.DeltaStep( delta_time ); if( time_for_fixed_step ) entity.FixedStep(); if( time_for_AI_step ) entity.AIStep(); ... // all kind of updates you want } PRO: you just have to iterate once over all entities. CON: fidelity could be lower at some scenarios, since the entity.FixedStep() isn't going all at a time. // Approach 2 step foreach( entity in entities ) entity.DeltaStep( delta_time ); if( time_for_fixed_step ) foreach( entity in entities ) entity.FixedStep(); if( time_for_AI_step ) foreach( entity in entities ) entity.FixedStep(); // all kind of updates you want SEPARATED PRO: fidelity on FixedStep is higher, shouldn't be much time between all entities update, rather than Approach 1 where you may have to wait other updates until FixedStep() comes. CON: you iterate once for each kind of update. Also, a third approach could be a hybrid between both of them, something in the way of foreach( entity in entities ) { entity.DeltaStep( delta_time ); if( time_for_AI_step ) entity.AIStep(); // all kind of updates you want BUT FixedStep() } if( time_for_fixed_step ) { foreach( entity in entities ) { entity.FixedStep(); } } Just two loops, don't caring about time fidelity in nothing other than at FixedStep(). Any thoughts on this matter? Should it really matters to make all steps at once or am I thinking on problems that don't exist?

• XNA 4: RenderTarget2D textures getting transparent on fullscreen

  - by Shashwat

  I'm generating a Texture2D object using RenderTarget2D as in the following code public static Texture2D GetTextTexture(string text, Vector2 position, SpriteFont font, Color foreColor, Color backColor, Texture2D background=null) { int width = (int)font.MeasureString(text).X; int height = (int)font.MeasureString(text).Y; GraphicsDevice device = Settings.game.GraphicsDevice; SpriteBatch spriteBatch = Settings.game.spriteBatch; RenderTarget2D renderTarget = new RenderTarget2D(device, width, height, false, SurfaceFormat.Color, DepthFormat.Depth24Stencil8, device.PresentationParameters.MultiSampleCount, RenderTargetUsage.DiscardContents); device.SetRenderTarget(renderTarget); device.Clear(backColor); spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.Opaque); if (background != null) spriteBatch.Draw(background, new Rectangle(0, 0, 70, 70), Color.White); spriteBatch.End(); spriteBatch.Begin(); spriteBatch.DrawString(font, text, position, foreColor, 0, new Vector2(0), 0.8f, SpriteEffects.None, 0); spriteBatch.End(); device.SetRenderTarget(null); ResetGraphicsDeviceSettings(); return (Texture2D)renderTarget; } It's working all fine. But when I ToggleFullScreen() (and vice-versa), the previous textures are getting transparent. However, the new textures after that are being generated correctly. What can be the reason for this?

• SlimDX Texture2D from DataRectangle array

  - by Rebekah Bryant

  I'm totally new to DirectX. I'm using SlimDX to create a texture consisting of 13046 DataRectangles. Here's my code. It's breaking on the Texture2D constructor with "E_INVALIDARG: An invalid parameter was passed to the returning function (-2147024809)." inParms is just a struct containing handle to a Panel. public Renderer(Parameters inParms, ref DataRectangle[] inShapes) { Texture2DDescription description = new Texture2DDescription() { Width = 500, Height = 500, MipLevels = 1, ArraySize = inShapes.Length, Format = Format.R32G32B32_Float, SampleDescription = new SampleDescription(1, 0), Usage = ResourceUsage.Default, BindFlags = BindFlags.RenderTarget | BindFlags.ShaderResource, CpuAccessFlags = CpuAccessFlags.None, OptionFlags = ResourceOptionFlags.None }; SwapChainDescription chainDescription = new SwapChainDescription() { BufferCount = 1, IsWindowed = true, Usage = Usage.RenderTargetOutput, ModeDescription = new ModeDescription(0, 0, new Rational(60, 1), Format.R8G8B8A8_UNorm), SampleDescription = new SampleDescription(1, 0), Flags = SwapChainFlags.None, OutputHandle = inParms.Handle, SwapEffect = SwapEffect.Discard }; Device.CreateWithSwapChain(DriverType.Hardware, DeviceCreationFlags.None, chainDescription, out mDevice, out mSwapChain); Texture2D texture = new Texture2D(Device, description, inShapes); } EDIT: Running with the Debug flag set, I got: D3D11 ERROR: ID3D11Device::CreateTexture2D: The format (0x6, R32G32B32_FLOAT) cannot be bound as a RenderTarget, or cast to a format that could be bound as a RenderTarget.

• LibGDX drawing map using tiles without space

  - by Enayat Muradi

  I am making a board game. To draw the map on the board I use different tiles. On some screen the map looks good but on some other screens there is a space between the tiles. How can I do so there won't be any space between the tiles? I am designing my game with the size 480x800. To fit other screens I stretch it. My tiles looks like this: I draw the map using a for loop to draw the tile in different (x,y) position on screen. Here is what I mean with space between tiles: Screen with 240x400 Screen with 360x600, here there is no spacing between tiles. I use camera and the screen to draw I don't use stage. I have also tried to use Viewport but I get the same results. cam = new OrthographicCamera();cam.setToOrtho(true, gameWidth, gameHeight); batcher = new SpriteBatch(); batcher.setProjectionMatrix(cam.combined); shapeRenderer = new ShapeRenderer(); shapeRenderer.setProjectionMatrix(cam.combined); How can I do to solve the problem?

• Input handling between game loops

  - by user48023

  This may be obvious and trivial for you but as I am a newbie in programming I come with a specific question. I have three loops in my game engine which are input-loop, update-loop and render-loop. Update-loop is set to 10 ticks per second with a fixed timestep, render-loop is capped at around 60 fps and the input-loop runs as fast as possible. I am using one of the Javascript frameworks which provide such things but it doesn't really matter. Let's say I am rendering a tile map and the view of which elements are rendered depends on camera-like movement variables which are modified during key pressing. This is only about camera/viewport and rendering, no game physics involved here. And now, how can I handle input events among these loops to keep consistent engine reaction? Am I supposed to read the current variable modified with input and do some needed calculations in a update-loop and share the result so it could be interpolated in a render-loop? Or read the input effect directly inside the render-loop and put needed calculations inside? I thought interpreting user input inside an update-loop with a low tick rate would be inaccurate and kind of unresponsive while rendering with interpolation in the final view. How it is done properly in games overall?

• How can I make permanent death in a MUD seem acceptable and fair to players?

  - by Luke Laupheimer

  I have considered writing a MUD for years, and I have a lot of ideas my friends think are really cool (and that's how I'd hope to get anywhere -- word of mouth). Thing is, there's one thing I have always wanted, that my friends and strangers hated: permanent death. Now, the emotional response I get to this is visceral revulsion, every time. I'm pretty sure I am the only person that wants this, or if I'm not, I'm a tiny minority. Now, the reason I want it is because I want the actions of the players to matter. Unlike a lot of other MUDs, which have a set of static city-states and social institutions etc, I want the things my players do, should I get any, to actually change the situation. And that includes killing people. If you kill someone, you didn't send them to time out, you killed them. What happens when you kill people? They go away. They don't come back in half an hour to smack talk you some more. They're gone. Forever. By making death non-permanent, you make death not matter. It would be similar if a climax to a character's arc is getting a speeding ticket. It cheapens it. Non-permanent death cheapens death. How can I: 1) Convince my players (and random people!) that this is actually a good idea?, or 2) Find some other way to make death and violence matter as much as it does in real life (except within the game, of course) sans character deletion? What alternatives are there out there?

• How to I access "Deny" message from a Lidgren client?

  - by TJ Mott

  I'm using the Lidgren v3 network for a UDP client/server networking model. On the server end, I'm initializing a NetServer object with the NetIncomingMessage.ConnectionApproval message type enabled. So the client is able to successfully connect and the first packet it sends is a login packet, containing a username and password supplied by the user. The server is receiving that and doing some black magic to authenticate, and everything works up to that point. If the login fails, the server calling NetIncomingMessage.SenderConnection.Deny("Invalid Login Credentials"). I want to know how to properly receive this deny message on the client. I'm getting the message, it shows up with a message type of NetIncomingMessage.StatusChanged. If I call ReadString on that message, I get a corrupted version of the string I passed to the Deny method on the server. The type of corruption varies, I've seen odd characters in there but in every case it's truncated and is way shorter than the string I entered. Any ideas? The official documentation is sparse on this topic. I could use pointers from anyone who has successfully used the Lidgren library and uses the Accept or Deny methods. Also, if I don't do any authentication and just Approve() the connection every time, stuff actually works just fine and I'm getting reliable two-way UDP traffic. (And lastly, Stack Exchange said I don't have enough reputation to use the "Lidgren" tag....???)

• Finding diagonal objects of an object in 3d space

  - by samfisher

  Using Unity3d, I have a array which is having 8 GameObjects in grid and one object (which is already known) is in center like this where K is already known object. All objects are equidistant from their adjacent objects (even with the diagonal objects) which means (distance between 4 & K) == (distance between K & 3) = (distance between 2 & K) 1 2 3 4 K 5 6 7 8 I want to remove 1,3,6,8 from array (the diagonal objects). How can I check that at runtime? my problem is the order of objects {1-8} is not known so I need to check each object's position with K to see if it is a diagonal object or not. so what check should I put with the GameObjects (K and others) to verify if this object is in diagonal position Regards, Sam

• Collider2D and Rigidbody2D, how do they work?

  - by user42646

  I have been learning JavaScript and Unity for a week now. I learned how to make Cube as a Ground and another Cube as a player and I used this code to make the Player Cube move forward and backward and jumping var walkspeed: float = 5.0; var jumpheight: float = 250.0; var grounded = false; function Update() { rigidbody.freezeRotation = true; if (Input.GetKey("a")) transform.Translate(Vector3(-1, 0, 0) * Time.deltaTime * walkspeed); if (Input.GetKey("d")) transform.Translate(Vector3(1, 0, 0) * Time.deltaTime * walkspeed); if (Input.GetButton("Jump")) { Jump(); } } function OnCollisionEnter(hit: Collision) { grounded = true; } function Jump() { if (grounded == true) { rigidbody.AddForce(Vector3.up * jumpheight); grounded = false; } } I also learned how to make a character hit box. how to make a sprite and animation. pretty much the basic stuff. Couple of days ago I created simple ground in Photoshop and a simple character and imported them to Unity3D. Whenever I use my code above the character keeps falling from the scene. Like the character has nothing to stand on. After thinking about it it make sense because I really didn't make anything to make the player character understand that he should stand on something so I started reading about this issue and I realized that there is something called Collider2D and Rigidbody2D. Now I'm really stuck here I just don't know what to do. I applied the rigibody2d to my character picture and the Collider2D to the ground picture but whenever I play the project the gravity makes my character falls down. This is my question: How can I make the rigibody2d object realize that it shouldn't fall if there is a Collider2D object under it? So when I jump it's going to jump and the gravity going to bring it back to the ground.
