• Share Your Top 30 Visited Domains with Visitation Cloud for Firefox

  - by Asian Angel

  Curious about the domains that you visit most or perhaps you want a way to share that information on a social website? Now you can see and share the 30 most visited domains in your browser’s history with the Visitation Cloud extension. Accessing Visitation Cloud As soon as you install the extension you can get started using it. Depending on how your browser’s UI is set up there are three methods for accessing Visitation Cloud: a “Visitation Cloud Button” inserted at the end of your “Bookmarks Toolbar”, a menu listing in the “Tools Menu”, and a “Toolbar Button” (not shown here). Visitation Cloud in Action As soon as you activate Visitation Cloud a new window will appear with your top domains displayed in a cloud format. Keep in mind that this is more than just a static image…each listing is actually a clickable link. Clicking on any of the listings will open that domain in a new tab or window depending on your particular browser settings. If you feel that you have a great set of links and want to share it with your friends then that is easy to do. Right click anywhere within the Visitation Cloud Window and select “Save as…”. The “cloud image” can be saved in “.png, .jpg, or Scalable Vector Graphics (.svg)” format. For our example we chose the “.svg format”. Perhaps you love the set of links but not the layout…right click and select “Randomize” to change how the cloud looks. Here is our cloud after being “Randomized”. Things definitely got moved around… Accessing the Visitation Cloud Image in other Browsers Once you have your “cloud image” saved you can share it with friends or save it for your own future use in other browsers. Here is our “cloud image” open in Opera Browser with link opening in progress. The same “cloud image” open in Google Chrome. Very nice… Conclusion While this may not be something that everyone will use Visitation Cloud does make for a rather unique, interesting, & fun way to access and share your most visited domains.

• How to move a sprite on a slope in chipmunk Spacemanager

  - by Anil gupta

  I have used one polygon shape image (terrain) in my game. It's just like a mountain, and now I want to move the tanker on a mountain path from one side to the other and then turn around at the edge of the screen and go back. I don't understand the method to move the tanker on the slope (image) path in chipmunk spacemanager. When collision detection happens like that, if any bomb falls on the slope (image of mountain) then I want to do a little damage to the slope (image of mountain) like this video.

• Running TeamCity from Amazon EC2 - Cloud based scalable build and continuous Integration

  - by RoyOsherove

  I’ve been having fun playing with the amazon EC2 cloud service. I set up a server running TeamCity, and an image of a server that just runs a TeamCity agent. I also setup TeamCity  to automatically instantiate agents on EC2 and shut them down based upon availability of free agents. Here’s how I did it: The first step was setting up the teamcity server. Create an account on amazon EC2 (BTW, amazon’s sites works better in IE than it does in chrome.. who knew!?) Open the EC2 dashboard, and click “Launch Instance” . From the “Quick Start” tab I selected from the list: “Getting Started on Microsoft Windows Server 2008 (AMI Id: ami-c5e40dac)” .  it’s good enough to just run teamcity. In the instance details, I used the default (Small instance, 1.7 GB mem). You might want to choose a close availability zone based on where you are. We want to “Launch instances” so click continue. Select the default kernel, RAM disk and all. No need to enable monitoring for now (you can do that later). click continue. If you don’t have a key pair, you will be prompted to create one. Once you do, select it in the list. Now you’ll be prompted to create a security group. I named mine “TC” as in “TeamCity”. each group is a bunch of settings on which ports can be let through into and out of a hosted machine.  keep it as the default settings. We will change them later. Click continue,  review and then click “Launch”. Now you’ll be able to see the new instance in the running instances list on your site. Now, you need to install stuff on that instance (TeamCity!) . To do that, you’ll need to Remote desktop into that instance. To do that, we’ll get the admin password for that instance: Check it on the list, and click “Instance Actions” - “Get Windows Admin Password”. You might have to wait about 10 minutes or so for the password to be generated for you. Once you have the password, you will remote desktop (start-run-‘mstsc’) into the instance. It’s address is a dns address shown below the list under “Public DNS”. it looks something like: ec2-256-226-194-91.compute-1.amazonaws.com Once you’re inside the instance – you’ll need to open IE (it is in hardened mode so you’ll have to relax its security settings to download stuff). I first downloaded chrome and using chrome I downloaded TeamCity. Note that the download speed is FAST. several MBs per second. To be able to see TeamCity from the outside, you will need to open the advanced firewall settings inside the remote machine, and add incoming and outgoing rules for port 80 (HTTP). Once you do that, you should be able to see the machine from the outside. If you still can’t, see the next step. I also enabled ports 9090 since I will use this machine to create an agent image later as well. Now configure the security group (TC) to enable talking to agents: IN the EC2 dashboard click on “Security Groups” and select your group. To add a rule, click on the empty list under the ‘protocol’ header. select TCP. from and ‘to’ ports are 9090. source ip is 0.0.0.0/0 (every ip is allowed). click “Save.  Also make sure you can see “HTTP” tcp 80 in that list. if you can’t see it, add it or you won’t be able to browse to the machine’s teamcity server home page. I also set an elastic IP for the machine: so I always have the same IP for the machine instance. Allocate and set one through the”Elastic IP” link on the EC2 dashboard.   you should now have a working instance of teamcity.   Now let’s create an agent image. Repeat steps 1-9, but this time, make sure you select a machine that fits what an agent might do. I selected Instance type – Hihg-CPU medium machine,  that is much faster. On that machine, I installed what I needed (VS 2010, PostSharp etc..). downloading VS 2010 from MSDN (2 GB took less than 10 min!) Now, instead of installing teamcity, browse using the browser to the teamcity homepage (from within the remote machine). go to the Administration page, and click the upper right link “Install agents”. Install the agent on he local machine – set it to the IP or DNS of the running TeamCity server. That way you’ll be able to check their connectivity live before making this machine your official agent image to reuse. Once the agent is installed, see that the TC server can see it and use it. see steps 13-14 above if they can’t. Once it works, you can take steps to make this image your agent image to be reused. next, here is a copy-paste of several steps to take from http://confluence.jetbrains.net/display/TCD5/Setting+Up+TeamCity+for+Amazon+EC2 Configure system so that agent it is started on machine boot (and make sure TeamCity server is accessible on machine boot). Test the setup by rebooting machine and checking that the agent connects normally to the server. Prepare the Image for bundling: Remove any temporary/history information in the system. Stop the agent (under Windows stop the service but leave it in Automatic startup type) Delete content agent logs and temp directories (not necessary) Delete "<Agent Home>/conf/amazon-*" file (not necessary) Change config/buildAgent.properties to remove properties: name, serverAddress, authToken (not necessary)   Now, we need to: Make AMI from the running instance. Configure TeamCity EC2 support on TeamCity server. Making an AMI: Check the instance of the agent in the EC2 dashboard instance list, and select instance actions->Create Image (EBS AMI) you’ll see the image pending in the APIs list in the EC2 dashboard. this could take 30 minutes or more. meanwhile we can configure the could support in the teamcity server. COPY THE AMI ID to the clipboard (looks like ami-a88aa4ce) Configuring TeamCity for Cloud: In TeamCity, click on “Agents” and then on “Cloud” tab. this is where you will control your cloud agents. to configure new cloud agents based on APIs, click on the right link to the “configuration page” Create a new profile and select AMazon EC2 as cloud type. Use your AMI ID that you copied to the clipboard into the “Images” field. Select an availability zone that is the same as the one your instance is running on for best communication perf between them make sure you select the ‘TC’ security group hopefully, that should be it, and teamcity will try to instantiate new instances on demand. Note that it may take around 10 minutes for an agent to become available to teamcity from the time it’s started.

• Computer Visionaries 2014 Kinect Hackathon

  - by T

  Originally posted on: http://geekswithblogs.net/tburger/archive/2014/08/08/computer-visionaries-2014-kinect-hackathon.aspxA big thank you to Computer Vision Dallas and Microsoft for putting together the Computer Visionaries 2014 Kinect Hackathon that took place July 18th and 19th 2014.  Our team had a great time and learned a lot from the Kinect MVP's and Microsoft team.  The Dallas Entrepreneur Center was a fantastic venue. In total, 114 people showed up to form 15 teams. Burger ITS & Friends team members with Ben Lower:  Shawn Weisfeld, Teresa Burger, Robert Burger, Harold Pulcher, Taylor Woolley, Cori Drew (not pictured), and Katlyn Drew (not pictured) We arrived Friday after a long day of work/driving.  Originally, our idea was to make a learning game for kids.  It was intended to be multi-simultaneous players dragging and dropping tiles into a canvas area for kids around 5 years old. We quickly learned that we were limited to two simultaneous players. After working on the game for the rest of the evening and into the next morning we decided that a fast multi-player game with hand gestures was not going to happen without going beyond what was provided with the API. If we were going to have something to show, it was time to switch gears. The next idea on the table was the Photo Anywhere Kiosk. The user can use voice and hand gestures to pick a place they would like to be.  After the user says a place (or anything they want) and then the word "search", the app uses Bing to display a bunch of images for him/her to choose from. With the use of hand gesture (grab and slide to move back and forth and push/pull to select an image) the user can get the perfect image to pose with. I couldn't get a snippet with the hand but when a the app is in use, a hand shows up to cue the user to use their hand to control it's movement. Once they chose an image, we use the Kinect background removal feature to super impose the user on that image. When they are in the perfect position, they say "save" to save the image. Currently, the image is saved in the images folder on the users account but there are many possibilities such as emailing it, posting to social media, etc.. The competition was great and we were honored to be recognized for third place. Other related posts: http://jasongfox.com/computer-visionaries-2014-incredible-success/ A couple of us are continuing to work on the kid's game and are going to make it a Windows 8 multi-player game without Kinect functionality. Stay tuned for more updates.

• How to install Diablo 2 Lord of Destruction?

  - by user99666

  I first tried to install Diablo 2 LOD from an iso image using acetone iso. However, after acetone iso mounted the image, it said "Please install the labelled disc". I then tried with Gmount, and, following advice I received from some forums, I attempted to create mount points and then install; after it mounted the image, it installed the first three disc images but not the expansion. When I tried to play, it told me to insert the labelled disc, even though the iso image was still mounted with Gmount. How can I resolve this problem?

• Can resizing images with css be good?

  - by Echo

  After reading Is CSS resizing of images still a bad idea?, I thought of a similar question. (too similar? should this be closed?) Lets say you need to use 10 different product image sizes throughout your website and you have 20k-30k different product images, should you use 10 different files for each image size? or maybe 5 different files and use css to resize the other 5? Would there ever be combination that would be good? Or should you always make separate image files? If you use css to resize them, you will save on storage (in GBs) but you will have slight increase in bandwidth and slower loading images(but if images are cached, and you show both sizes of the image would you use less bandwidth and have faster loads?) (But of course you wouldn't want to use css to resize images for mobile sites.)

• iOS - pass UIImage to shader as texture

  - by martin pilch

  I am trying to pass UIImage to GLSL shader. The fragment shader is: varying highp vec2 textureCoordinate; uniform sampler2D inputImageTexture; uniform sampler2D inputImageTexture2; void main() { highp vec4 color = texture2D(inputImageTexture, textureCoordinate); highp vec4 color2 = texture2D(inputImageTexture2, textureCoordinate); gl_FragColor = color * color2; } What I want to do is send images from camera and do multiply blend with texture. When I just send data from camera, everything is fine. So problem should be with sending another texture to shader. I am doing it this way: - (void)setTexture:(UIImage*)image forUniform:(NSString*)uniform { CGSize sizeOfImage = [image size]; CGFloat scaleOfImage = [image scale]; CGSize pixelSizeOfImage = CGSizeMake(scaleOfImage * sizeOfImage.width, scaleOfImage * sizeOfImage.height); //create context GLubyte * spriteData = (GLubyte *)malloc(pixelSizeOfImage.width * pixelSizeOfImage.height * 4 * sizeof(GLubyte)); CGContextRef spriteContext = CGBitmapContextCreate(spriteData, pixelSizeOfImage.width, pixelSizeOfImage.height, 8, pixelSizeOfImage.width * 4, CGImageGetColorSpace(image.CGImage), kCGImageAlphaPremultipliedLast); //draw image into context CGContextDrawImage(spriteContext, CGRectMake(0.0, 0.0, pixelSizeOfImage.width, pixelSizeOfImage.height), image.CGImage); //get uniform of texture GLuint uniformIndex = glGetUniformLocation(__programPointer, [uniform UTF8String]); //generate texture GLuint textureIndex; glGenTextures(1, &textureIndex); glBindTexture(GL_TEXTURE_2D, textureIndex); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); //create texture glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, pixelSizeOfImage.width, pixelSizeOfImage.height, 0, GL_RGBA, GL_UNSIGNED_BYTE, spriteData); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, textureIndex); //"send" to shader glUniform1i(uniformIndex, 1); free(spriteData); CGContextRelease(spriteContext); } Uniform for texture is fine, glGetUniformLocation function do not returns -1. The texture is PNG file of resolution 2000x2000 pixels. PROBLEM: When the texture is passed to shader, I have got "black screen". Maybe problem are parameters of the CGContext or parameters of the function glTexImage2D Thank you

• Google Analytics and direct access

  - by user1592845

  Does Google analytics regards remote access resources as direct access? For example: Suppose: mysite.com and anothersite.com mysite.com has an image found at http://mysite.com/img/vip.jpg anothersite.com at some page of it like http://anothersite.com/photos.html included vip.jpg in its source in image tag: <img src="http://mysite.com/img/vip.jpg" /> So does Analytics regard loading this image when a visitor vists http://anothersite.com/photos.html to be a direct access for mysite.com?

• Difficulties with rotation of a sprite

  - by Johnny

  I want to program a dolphin that jumps and rotates like a real dolphin. Jumping is not the problem, but I don't know how to make the rotation. At the moment, my dolphin rotates a little weird. But I want that it rotates like a real dolphin does. How can I improve the rotation? public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; Texture2D image, water; float Gravity = 5.0F; float Acceleration = 20.0F; Vector2 Position = new Vector2(1200,720); Vector2 Velocity; float rotation = 0; SpriteEffects flip; Vector2 Speed = new Vector2(0, 0); public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; graphics.PreferredBackBufferWidth = 1280; graphics.PreferredBackBufferHeight = 720; } protected override void Initialize() { base.Initialize(); } protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); image = Content.Load<Texture2D>("cartoondolphin"); water = Content.Load<Texture2D>("background"); flip = SpriteEffects.None; } protected override void Update(GameTime gameTime) { float VelocityX = 0f; float VelocityY = 0f; float time = (float)gameTime.ElapsedGameTime.TotalSeconds; KeyboardState kbState = Keyboard.GetState(); if(kbState.IsKeyDown(Keys.Left)) { rotation = 0; flip = SpriteEffects.None; VelocityX += -5f; } if(kbState.IsKeyDown(Keys.Right)) { rotation = 0; flip = SpriteEffects.FlipHorizontally; VelocityX += 5f; } // jump if the dolphin is under water if(Position.Y >= 670) { if (kbState.IsKeyDown(Keys.A)) { if (flip == SpriteEffects.None) { rotation += 0.01f; VelocityY += 40f; } else { rotation -= 0.01f; VelocityY += 40f; } } } else { if (flip == SpriteEffects.None) { rotation -= 0.01f; VelocityY += -10f; } else { rotation += 0.01f; VelocityY += -10f; } } float deltaY = 0; float deltaX = 0; deltaY = Gravity * (float)gameTime.ElapsedGameTime.TotalSeconds; deltaX += VelocityX * (float)gameTime.ElapsedGameTime.TotalSeconds * Acceleration; deltaY += -VelocityY * (float)gameTime.ElapsedGameTime.TotalSeconds * Acceleration; Speed = new Vector2(Speed.X + deltaX, Speed.Y + deltaY); Position += Speed * (float)gameTime.ElapsedGameTime.TotalSeconds; Velocity.X = 0; if (Position.Y + image.Height/2 > graphics.PreferredBackBufferHeight) Position.Y = graphics.PreferredBackBufferHeight - image.Height/2; base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); spriteBatch.Begin(); spriteBatch.Draw(water, new Rectangle(0, graphics.PreferredBackBufferHeight -100, graphics.PreferredBackBufferWidth, 100), Color.White); spriteBatch.Draw(image, Position, null, Color.White, rotation, new Vector2(image.Width / 2, image.Height / 2), 1, flip, 1); spriteBatch.End(); base.Draw(gameTime); } }

• SEO - Index images (lazyload)

  - by Guilherme Nascimento

  Note:My question is not about Javascript. I'm developing a plugin for jQuery/Mootols/Prototype, that work with DOM. This plugin will be to improve page performance (better user experience). The plugin will be distributed to other developers so that they can use in their projects. How does the lazyload: The images are only loaded when you scroll down the page (will look like this: http://www.appelsiini.net/projects/lazyload/enabled_timeout.html LazyLoad). But he does not need HTML5, I refer to this attribute: data-src="image.jpg" Two good examples of website use LazyLoad are: youtube.com (suggested videos) and facebook.com (photo gallery). I believe that the best alternative would be to use: <A href="image.jpg">Content for ALT=""</a> and convert using javascript, for this: <IMG alt="Content for ALT=\"\"" src="image.jpg"> Then you question me: Why do you want to do that anyway? I'll tell you: Because HTML5 is not supported by any browser (especially mobile) And the attribute data-src="image.jpg" not work at all Indexers. I need a piece of HTML code to be fully accessible to search engines. Otherwise the plugin will not be something good for other developers. I thought about doing so to help in indexing: <noscript><img src="teste.jpg"></noscript> But noscript has negative effect on the index (I refer to the contents of noscript) I want a plugin that will not obstruct the image indexing in search engines. This plugin will be used by other developers (and me too). This is my question: How to make a HTML images accessible to search engines, which can minimize the requests?

• SDL to SFML simple question

  - by ultifinitus

  Hey! I've been working on a game in c++ for about a week and a half, and I've been using SDL. However, my current engine only needs the following from whatever library I use: enable double buffering load an image from path into something that I can apply to the screen apply an image to the screen with a certain x,y enable transparency on an image (possibly) image clipping, for sprite sheets. I am fairly sure that SFML has all of this functionality, I'm just not positive. Will someone confirm my suspicions? Also I have one or two questions regarding SFML itself. Do I have to do anything to enable hardware accelerated rendering? How quick is SFML at blending alpha values? (sorry for the less than intelligent question!)

• Hotlinking images in Outlook emails

  - by Alexander Voglund

  I want to create an email with a signature that contains an external image. For example, I would like to always include my SuperUser flair in my signature like so: http://superuser.com/users/flair/53525.png This can be done if I insert an image and select the above source. The problem occurs when I copy the image and paste it into the body of a new email. Outlook creates an embedded version and breaks the link to the original email. How can an image be pasted into Outlook and NOT be embedded (ie: the link to the original image is maintained?)

• Imaging: Paper Paper Everywhere, but None Should be in Sight

  - by Kellsey Ruppel

  Author: Vikrant Korde, Technical Architect, Aurionpro's Oracle Implementation Services team My wedding photos are stored in several empty shoeboxes. Yes...I got married before digital photography was mainstream...which means I'm old. But my parents are really old. They have shoeboxes filled with vacation photos on slides (I doubt many of you have even seen a home slide projector...and I hope you never do!). Neither me nor my parents should have shoeboxes filled with any form of photographs whatsoever. They should obviously live in the digital world...with no physical versions in sight (other than a few framed on our walls). Businesses grapple with similar challenges. But instead of shoeboxes, they have file cabinets and warehouses jam packed with paper invoices, legal documents, human resource files, material safety data sheets, incident reports, and the list goes on and on. In fact, regulatory and compliance rules govern many industries, requiring that this paperwork is available for any number of years. It's a real challenge...especially trying to find archived documents quickly and many times with no backup. Which brings us to a set of technologies called Image Process Management (or simply Imaging or Image Processing) that are transforming these antiquated, paper-based processes. Oracle's WebCenter Content Imaging solution is a combination of their WebCenter suite, which offers a robust set of content and document management features, and their Business Process Management (BPM) suite, which helps to automate business processes through the definition of workflows and business rules. Overall, the solution provides an enterprise-class platform for end-to-end management of document images within transactional business processes. It's a solution that provides all of the capabilities needed - from document capture and recognition, to imaging and workflow - to effectively transform your ‘shoeboxes’ of files into digitally managed assets that comply with strict industry regulations. The terminology can be quite overwhelming if you're new to the space, so we've provided a summary of the primary components of the solution below, along with a short description of the two paths that can be executed to load images of scanned documents into Oracle's WebCenter suite. WebCenter Imaging (WCI): the electronic document repository that provides security, annotations, and search capabilities, and is the primary user interface for managing work items in the imaging solution SOA & BPM Suites (workflow): provide business process management capabilities, including human tasks, workflow management, service integration, and all other standard SOA features. It's interesting to note that there a number of 'jumpstart' processes available to help accelerate the integration of business applications, such as the accounts payable invoice processing solution for E-Business Suite that facilitates the processing of large volumes of invoices WebCenter Enterprise Capture (WEC): expedites the capture process of paper documents to digital images, offering high volume scanning and importing from email, and allows for flexible indexing options WebCenter Forms Recognition (WFR): automatically recognizes, categorizes, and extracts information from paper documents with greatly reduced human intervention WebCenter Content: the backend content server that provides versioning, security, and content storage There are two paths that can be executed to send data from WebCenter Capture to WebCenter Imaging, both of which are described below: 1. Direct Flow - This is the simplest and quickest way to push an image scanned from WebCenter Enterprise Capture (WEC) to WebCenter Imaging (WCI), using the bare minimum metadata. The WEC activities are defined below: The paper document is scanned (or imported from email). The scanned image is indexed using a predefined indexing profile. The image is committed directly into the process flow 2. WFR (WebCenter Forms Recognition) Flow - This is the more complex process, during which data is extracted from the image using a series of operations including Optical Character Recognition (OCR), Classification, Extraction, and Export. This process creates three files (Tiff, XML, and TXT), which are fed to the WCI Input Agent (the high speed import/filing module). The WCI Input Agent directory is a standard ingestion method for adding content to WebCenter Imaging, the process for doing so is described below: WEC commits the batch using the respective commit profile. A TIFF file is created, passing data through the file name by including values separated by "_" (underscores). WFR completes OCR, classification, extraction, export, and pulls the data from the image. In addition to the TIFF file, which contains the document image, an XML file containing the extracted data, and a TXT file containing the metadata that will be filled in WCI, are also created. All three files are exported to WCI's Input agent directory. Based on previously defined "input masks", the WCI Input Agent will pick up the seeding file (often the TXT file). Finally, the TIFF file is pushed in UCM and a unique web-viewable URL is created. Based on the mapping data read from the TXT file, a new record is created in the WCI application.  Although these processes may seem complex, each Oracle component works seamlessly together to achieve a high performing and scalable platform. The solution has been field tested at some of the largest enterprises in the world and has transformed millions and millions of paper-based documents to more easily manageable digital assets.

• Do any CDN services offer multiple urls (or aliases) for your files?

  - by Jakobud

  Lets say a company has multiple commercial web properties that happen to use a lot of the same images on each site. For SEO reasons, the sites must not appear to be related to eachother in any way. This means that the sites can't all link to the same image, even though they all use the same one. Therefore, an image is uploaded to each site and served from each site separately. In order to improve maintainability and latency, lets say the company wanted to use a CDN service. What I'm wondering is, if you upload a file, like an image or something, to a CDN, is there basically one single URL that you access that image at? Or do some (or all) CDN services offer alias URLs so that you can access the same resource from multiple URLs? Example of undesirable situation: Both sites link to the same file URL Site ABC links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Site XYZ links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Example of DESIRABLE situation: Both sites link to the same file via different URLs Site ABC links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Site XYZ links to <img src="http://123.cdnservice.com/some-alias-path/myimage.jpg"/> So in the end, there is only one single file, myimage.jpg on the CDN server, but it is accessible from multiple URLs. Is this possible with CDN services? I know this would make browsers cache the same image twice, but at least it would be better for maintainability. Only one file would ever have to be uploaded.

• Hybrid USB Install Method - netboot and iso

  - by Samus Arin

  I was following the steps here ("Preparing Files for USB Memory Stick Booting") https://help.ubuntu.com/10.04/installation-guide/i386/boot-usb-files.html to create a installation usb drive for 12.1. The very first paragraph of the article states "The second is to also copy a CD image onto the USB stick and use that as a source for packages, possibly in combination with a mirror." However, the only instructions mentioned regarding an iso image is to simply copy one somewhere on the drive (after its been made bootable and syslinux, vmlinuz and initrd.gz installed/copied): "you should now copy an Ubuntu ISO image onto the stick." I thought it strange there where no configuration steps for "pointing" the kernel to the iso (like a line in syslinux.cfg or a boot: option or something), but went ahead with the install anyway. I don't think the iso was used at all, it appeared that all the OS files where downloaded during the install process. Therefore, I was wondering if anyone knew how to use this local iso image in this particular installation technique (I know the image can be installed with dd, but thats a different technique), b/c I need to reinstall (I installed unity, but it's wayy to much for my little Atom based netbook) ? Thank you.

• Producing a smooth mesh from density cloud and marching cubes

  Based on my results from this question I decided to build myself a 3D noise map containing float values in place of my existing boolean point values. The effect I'm trying to produce is something like this, rather than typical rolling hills; which should explain the "missing cubes" in the image below. If I render my density map in normal "minecraft mode" (1 block per point in the density map) varying the size of the cube based on the value in my density map (floats in the range 0 to 1) I get something like this: I'm now happy that I can produce a density map for the marching cubes algorithm (which will need a little tweaking) but for some reason when I run it through my implementation it's not producing what I expect. My problem is that I'm getting something like the first image in this answer to my previous question, when I want to achieve the effect in the second image. Upon further investigation I can't see how marching cubes does the "move vertex along the edge" type logic (i.e. the difference between the two images on my previous link). I see that it does do some interpolation, but I'm not convinced I have the correct understanding of what I think it should do, because the code in question appears to give the same result regardless of whether I use boolean or float values. I took the code from here which is a C# implementation of marching cubes, but instead of using the MarchingCubesPrimitive I modified it to accept an object of type IDrawable, containing lists for the various collections (vertices, normals, UVs, indices), the logic was otherwise untouched. My understanding is that given a very low isovalue the accuracy level of the surface being rendered should increase, so in short "less 45 degree slows more rolling hills" type mesh output. However this isn't what I'm seeing. Have I missed something or is the implementation flawed and need to be fixed? EDIT: A little more detail on what I am seeing when I "marching cube" the data. Ok so firstly, ignore the fact that the meshes created by the chunks don't "connect" (i'll probably raise another question about this later). Then look at the shaping of the island, it's too ... square, from the voxels rendered as boxes you get the impression there's a clean soft gradual hill and yet from the image there are sharp falling edges even in the most central areas where the gradient in the first image looks the most smooth. The data is "regenerated" each time I run this so no 2 islands come out the same, and it's purely random so not based on noise, but still, how can it look so smooth in 1 image and so not smooth in the other?

• Map building - Tower Defense

  - by Dan K

  Before diving too deep into my question, let it be known that I am learning as far as java script goes and figured a simple Tower Defense game would be an excellent way to learn things. So I have found a simple background image with a path drawn on it and my question is how would I go about building a path so that I can animate my objects. Would I have to take the image and overlay a grid system, or can I store the path in some sort of array and have my objects move across it? Here is the background image:

• Is there any hueristic to polygonize a closed 2d-raster shape with n triangles?

  - by Arthur Wulf White

  Lets say we have a 2d image black on white that shows a closed geometric shape. Is there any (not naive brute force) algorithm that approximates that shape as closely as possible with n triangles? If you want a formal definition for as closely as possible: Approximate the shape with a polygon that when rendered into a new 2d image will match the largest number of pixels possible with the original image.

• About Alpha blending sprites in Direct3D9

  - by ambrozija

  I have a Direct3D9 application that is rendering ID3DXSprites. The problem I am experiencing is best described in this situation: I have a texture that is totally opaque. On top of it I draw a rectangle filled with solid color and alpha of 128. On top of the rectangle I have a text that is totally opaque. I draw all of this and get the resulting image through GetRenderTarget call. The problem is that on the resulting image, on the area where the transparent rectangle is, I have semi transparent pixels. It is not a problem that the rectangle is transparent, the problem is that the resulting image is. The question is how to setup the blending so in this situation I don't get the transparent pixels in the resulting image? I use the sprite with D3DXSPRITE_ALPHABLEND which sets the device state to D3DBLEND_SRCALPHA and D3DBLEND_INVSRCALPHA. I tried couple of combinations of SetRenderState, like D3DBLEND_SRCALPHA, D3DBLEND_DESTALPHA etc., but couldn't make it work. Thanks.

• How does Google show a web page's recipe photo inline with the search results? How'd they do that?

  - by Pete Alvin

  On Google, if you search for "chana dal recipe," in the middle of the search results page you'll see one search result with an image of the meal, taken from the underlying web page. It's the only one. Did: A) Google someone magically isolate the one image on the web page which summarized the recipe, --or-- B) did the webmaster/page author somehow designate and promote that particular image so that Google would inline it in the search results?

• genisoimage and exec bit preservation

  - by user92187

  Maybe I'm just not doing right, but I can't seem to get genisoimage to produce a UDF image and preserve the exec bit. $ genisoimage --version genisoimage 1.1.11 (Linux) $ echo "echo 'Hello world'" > script.sh $ chmod +x script.sh $ ./script.sh Hello world $ genisoimage -input-charset utf-8 -r -udf -volid minimal -o minimal.iso script.sh Total translation table size: 0 Total rockridge attributes bytes: 250 Total directory bytes: 0 Path table size(bytes): 10 Max brk space used 0 420 extents written (0 MB) $ mkdir mount $ sudo mount minimal.iso $PWD/mount -o ro,loop -t udf $ ls -l script.sh mount/script.sh -r--r--r-- 1 root root 19 Sep 21 18:40 mount/script.sh -rwxrwxr-x 1 kip kip 19 Sep 21 18:40 script.sh You'll note in the last command that script.sh was executable at the time it was injected into the image, but does not appear to be inside of the mounted image. Is this a bug in genisoimage, a problem with the way I am mounting the image, or a problem in my usage of genisoimage?

• How To Get Browser To Open From Same Folder?

  - by Bad Learner

  I don't know how to make the title any more clear. Let me give an example - When I want to add an image to an article on my blog, I click "Browse" button in the image uploader, and then upload the image to the blog. The problem is, when I want to upload another image to my blog, I want the browser to look into the same directory; but it's always takes me to the "Recently Used" directory. Is there a way to change this? I hope I have made myself clear enough. EDIT: I only use Chrome, so I am referring to it.
