• Does "diff" exist for images?

  - by moose

  You can compare two text files very easy with diff and even better with meld: If you use diff for images, you get an example like this: $ diff zivi-besch.tif zivildienst.tif Binary files zivi-besch.tif and zivildienst.tif differ Here is an example: Original from http://commons.wikimedia.org/wiki/File:Tux.svg Edited: I've added a white background to both images and applied GIMPs "Difference" filter to get this: It is a very simple method how a diff could work, but I can imagine much better (and more complicated) ones. Do you know a program which works for images like meld does for texts? (If a program existed that could give a percentage (0% the same image - 100% the same image) I would also be interested in it, but I am looking for one that gives me visual hints where differences are.)

• Technical Screencast Series

  - by Ben Griswold

  Noah and I have started to produce a series of technical screencasts. In the spirit of Dimecasts.net, we’re limiting each episode to ten minutes as we thought the development community could benefit from short, focused episodes. We’re just getting started, but I’m really pleased with our progress and I’m very excited about what’s to come.  The first three episodes are focused on the .NET stack (specifically around Visual Studio Solution Setup, Managing .NET External Dependencies and Working with the ASP.NET Membership Provider) but since we work for a mixed shop of .NET and Java development, I’m sure we’ll eventually introduce all sorts of topics. We’re currently putting together a list of shows. If you have suggestions, please let me know. I plan to post the episodes to johnnycoder as they roll out and who knows?  Maybe your screencast idea will show up next.

• choosing Database and Its Design for Rails

  - by Gaurav Shah

  I am having a difficulty in deciding the database & its structure. Let us say the problem is like this. For my product I have various customers( each is an educational institute) Each customer have their own sub-clients ( Institution have students) Each student record will have some basic information like "name" & "Number" . There are also additional information that a customer(institution) might want to ask sub-client(student) like "email" or "semester" I have come up with two solutions : 1. Mysql _insititution__ id-|- Description| __Student__ id-|-instituition_id-|-Name-|-Number| __student_additional_details__ student_id -|- field_name -|- Value Student_additional_details will have multiple records for each student depending upon number of questions asked from institution. 2.MongoDb _insititution___ id-|- Description| _Student__ id-|-instituition_id-|-Name-|-Number|-otherfield1 -|- otherfield2 with mongo the structure itself can be dynamic so student table seems really good in mongo . But the problem comes when I have to relate student with institution . So which one is a better design ? Or some other idea ?

• Polished DIY Projector Is Painted Right onto the Wall

  - by Jason Fitzpatrick

  If you’re contemplating building a projector screen but find yourself not entirely unhappy with just projecting right onto the wall, this simple paint-it-on-the-wall upgrade is for you. Check out the above video to see the steps required to patch, paint, and frame a space on your wall to serve as a projection screen. You’ll need spackle, sandpaper, white paint, and some very basic carpentry skills to complete the simple wood frame for your painted-on screen. If you’d like to create a screen using the same technique but make it removable (for adjustments or to take it with you when you move out) you can just as easily use the paint-it-on technique with a piece of hardboard instead of the drywall.

• How to apply numerical integration on a graph layout

  - by Cumatru

  I've done some basic 1 D integration, but i can't wrap my head around things and apply it to my graph layout. So, consider the picture below: if i drag the red node to the right, i'm forcing his position to my mouse position the other nodes will "follow" him, but how ? For Verlet, to compute the newPosition, i need the acceleration for every node and the currentPosition. That is what i don't understand. How to i compute the acceleration and the currentPosition ? The currentPosition will be the position of the RedNode ? If yes, doesn't that means that they will all overlap ? http://i.stack.imgur.com/NCKmO.jpg

• Determining if you&rsquo;re running on the build server with MSBuild &ndash; Easy way

  - by ParadigmShift

  When you're customizing MSBuild in building a visual studio project, it often becomes important to determine if the build is running on the build server or your development environment. This information can change the way you set up path variables and other Conditional tasks.I've found many different answers online. It seems like they all only worked under certain conditions, so none of them were guaranteed to be consistent.So here's the simplest way I've found that has not failed me yet. <PropertyGroup> <!-- Determine if the current build is running on the build server --> <IsBuildServer>false</IsBuildServer> <IsBuildServer Condition="'$(BuildUri)' != ''">true</IsBuildServer> </PropertyGroup>   Shahzad Qureshi is a Software Engineer and Consultant in Salt Lake City, Utah, USAHis certifications include:Microsoft Certified System Engineer 3CX Certified Partner Global Information Assurance Certification – Secure Software Programmer – .NETHe is the owner of Utah VoIP Store at www.UtahVoIPStore.com and SWS Development at www.swsdev.com and publishes windows apps under the name Blue Voice.

• KnownType Not sufficient for Inclusion

  - by Kate at LittleCollie

  Why isn't the use of KnownType attribute in C# sufficient for inclusion of a DLL? Working with Visual Studio 2012 with TFS responsible for builds, I am on a project in which a service required use of this attribute as in the following: using Project.That.Contains.RequiredClassName; [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, Namespace="SomeNamespace")] [KnownType(typeof(RequiredClassName))] public class Service : IService { } But to get the required DLL to be included in the bin output and therefore the installer from our production build, I had to add the follow to the constructor for Service: public Service() { // Exists only to force inclusion var ignore = new RequiredClassName(); } So, given that the project that contains RequiredClassName is itself referenced by the project that contains Service, why isn't the use of the KnownType attribute sufficient for inclusion of DLL in the output?

• Upgrading ASP.NET AJAX 1.0 Websites to .NET 4.5

  - by Lijo

  I have an existing website in ASP.Net 2.0 that uses ASP.Net Ajax 1.0. This is developed using Visual Studio 2005. Now, we are planning to upgrade this to .Net 4.5 and VS2013. When I made a search, I could see that there are blogs about upgrading projects with Ajax 1.0 to .Net 3.5 version. However I could not find useful links for upgrading to .Net 4.5. Do we have any useful links for that? Or is it an unworkable approach? Note: As of now we have not purchased VS2013 and servers for this. Purchase depends on the feasibility study. Hence I cannot test it myself, at present. Upgrading ASP.NET AJAX 1.0 Websites and Web Applications to .NET Framework 3.5 How To: Upgrade an ASP.NET AJAX 1.0 Web Project to .NET Framework 3.5

• Why are Awstats, Webalizer, and Google Analytics results so different?

  - by Matt

  I realize that comparing Awstats and Webalizer to Google Analytics is like comparing apples to oranges, but each of them track at least basic statistics about visitors and pages. So why are there often very significant differences in their data? For example, comparing Analytics with Awstats using some numbers from a small site over the past week: Awstats 78 unique visitors 205 visits (2.62 visits/visitor) 1,072 pages (5.22 pages/visit) Google Analytics 115 unique visitors 240 visits (2.08 visits/visitor) 1,275 pages (5.31 pages/visit) They're similar on the number of visits, but page views and uniques are quite different. I'm familiar with discrepancies of a much higher magnitude on some larger sites, showing that this trend scales proportionally upward. What is the reason behind the different numbers, even when the data is quite trivial like unique visitors and page loads?

• POV Christmas Tree Is a Holiday-Themed DIY Electronics Project

  - by Jason Fitzpatrick

  If you’re looking for an electronics project with a bit of holiday cheer, this clever POV Christmas tree combines LEDs, motors, and a simple vision hack to create a glowing Christmas tree. POV (or Persistence Of Vision) hacks rely on your visual circuit’s lag time. By taking advantage of that lag POV displays can create the illusion of shapes and words where there are none. In the case of this Christmas tree hack a spinning set of LED lights creates the illusion of a Christmas tree when, in reality, there is just a few LEDs suspended in space by wire. It’s not a beginner level project by any means but it is a great way to practice surface mounting electronics and polish up your PCB making skills. Hit up the link below for the full tutorial.

• Online games programming basics

Basic games like a TIC-TAC-TOE or a SNAKE were done already, and I would like to do a simple, but online, game. Would you mind giving me some tutorials or guides related to that? I would really like to learn how to work online with the client/server structure (though, I do know the basics about that structure). I look forward to reading from you. Yours faithfully, Renkon.

• aspnet_regiis -lk is not listing the site I need

  - by Luke Duddridge

  I am trying to release a site to run under framework 4 on a server that also hosts framework 2 sites. By default the App has defaulted to framework 2, but when I try to change it's framework to 4 I get a message saying that the following action will cause the iis to reset. The problem I have is there are serveral active sites that I do not want to interupt with a restart. The message goes on to say you can avoid restarting by running the following: aspnet_regiis -norestart -s [IIS Virtual Path] I have been attempting to find the site virtual path but when I run aspnet_regiis -lk the site I am after does not appear to be listed. My first thoughts were that it has something to do with the app pool?, but I'm sure I saw sites that are inactive listed, and after creating a basic site to get it to run under framework 2, the site still did not appear in the -lk list. Can anyone tell me if there is an alternative location to the -lk that I can find the specific information realating to the IIS Virtual Path?

• Optimizing collision engine bottleneck

  - by Vittorio Romeo

  Foreword: I'm aware that optimizing this bottleneck is not a necessity - the engine is already very fast. I, however, for fun and educational purposes, would love to find a way to make the engine even faster. I'm creating a general-purpose C++ 2D collision detection/response engine, with an emphasis on flexibility and speed. Here's a very basic diagram of its architecture: Basically, the main class is World, which owns (manages memory) of a ResolverBase*, a SpatialBase* and a vector<Body*>. SpatialBase is a pure virtual class which deals with broad-phase collision detection. ResolverBase is a pure virtual class which deals with collision resolution. The bodies communicate to the World::SpatialBase* with SpatialInfo objects, owned by the bodies themselves. There currenly is one spatial class: Grid : SpatialBase, which is a basic fixed 2D grid. It has it's own info class, GridInfo : SpatialInfo. Here's how its architecture looks: The Grid class owns a 2D array of Cell*. The Cell class contains two collection of (not owned) Body*: a vector<Body*> which contains all the bodies that are in the cell, and a map<int, vector<Body*>> which contains all the bodies that are in the cell, divided in groups. Bodies, in fact, have a groupId int that is used for collision groups. GridInfo objects also contain non-owning pointers to the cells the body is in. As I previously said, the engine is based on groups. Body::getGroups() returns a vector<int> of all the groups the body is part of. Body::getGroupsToCheck() returns a vector<int> of all the groups the body has to check collision against. Bodies can occupy more than a single cell. GridInfo always stores non-owning pointers to the occupied cells. After the bodies move, collision detection happens. We assume that all bodies are axis-aligned bounding boxes. How broad-phase collision detection works: Part 1: spatial info update For each Body body: Top-leftmost occupied cell and bottom-rightmost occupied cells are calculated. If they differ from the previous cells, body.gridInfo.cells is cleared, and filled with all the cells the body occupies (2D for loop from the top-leftmost cell to the bottom-rightmost cell). body is now guaranteed to know what cells it occupies. For a performance boost, it stores a pointer to every map<int, vector<Body*>> of every cell it occupies where the int is a group of body->getGroupsToCheck(). These pointers get stored in gridInfo->queries, which is simply a vector<map<int, vector<Body*>>*>. body is now guaranteed to have a pointer to every vector<Body*> of bodies of groups it needs to check collision against. These pointers are stored in gridInfo->queries. Part 2: actual collision checks For each Body body: body clears and fills a vector<Body*> bodiesToCheck, which contains all the bodies it needs to check against. Duplicates are avoided (bodies can belong to more than one group) by checking if bodiesToCheck already contains the body we're trying to add. const vector<Body*>& GridInfo::getBodiesToCheck() { bodiesToCheck.clear(); for(const auto& q : queries) for(const auto& b : *q) if(!contains(bodiesToCheck, b)) bodiesToCheck.push_back(b); return bodiesToCheck; } The GridInfo::getBodiesToCheck() method IS THE BOTTLENECK. The bodiesToCheck vector must be filled for every body update because bodies could have moved meanwhile. It also needs to prevent duplicate collision checks. The contains function simply checks if the vector already contains a body with std::find. Collision is checked and resolved for every body in bodiesToCheck. That's it. So, I've been trying to optimize this broad-phase collision detection for quite a while now. Every time I try something else than the current architecture/setup, something doesn't go as planned or I make assumption about the simulation that later are proven to be false. My question is: how can I optimize the broad-phase of my collision engine maintaining the grouped bodies approach? Is there some kind of magic C++ optimization that can be applied here? Can the architecture be redesigned in order to allow for more performance? Actual implementation: SSVSCollsion Body.h, Body.cpp World.h, World.cpp Grid.h, Grid.cpp Cell.h, Cell.cpp GridInfo.h, GridInfo.cpp
