  • Gotcha | Installing .net 4.0 and IIS 6

    - by Steve Clements
    Just a quick one, seems pretty weird to me. I installed .net 4.0 on an old IIS6 box, ready to deploy a asp.net mvc app targeting .net 4.0.  I thought, which to me seems logical, that I install .net 4.0, setup a new web site, new app pool, set the web site to asp.net 4.0 (other configuration also needed to run MVC on IIS6 here and here) and it would just work. Errr… No.  The page cannot be displayed!  Nothing to do with MVC. Apparently just because you have installed .net 4 and the option is available in IIS, it’s not enabled.  I’m not going to repeat anything here…take a look at this post – clear, easy steps on exactly what you need to do and how to check if this is the problem. http://johan.driessen.se/archive/2010/04/13/getting-an-asp.net-4-application-to-work-on-iis6.aspx

  • Zune API Library for Ruby

    - by kerry
    Those of you who know me, know my favorite music player is the Zune. For some reason it seems most of my spare time lately seems to be creating Zune API libraries for different languages (I have a PHP one as well).  Here’s another one for Ruby!  If you use it, let me know.  I would love to hear what people are working on. It’s hosted at github, and very easy to use. zune_card = Zune::ZuneCard.for('a_zune_tag') Checkout the README for deets on what fields the object will have.

  • How do I determine the draw order in an isometric view flash game?

    - by Gajet
    This is for a flash game, with isometric view. I need to know how to sort object so that there is no need for z-buffer checking when drawing. This might seem easy but there is another restriction, a scene can have 10,000+ objects so the algorithm needs to be run in less than O(n^2). All objects are rectangular boxes, and there are 3-4 objects moving in the scene. What's the best way to do this? UPDATE in each tile there is only object (I mean objects can stack on top of each other). and we access to both map of Objects and Objects have their own position.

  • Looking for a light weight note program.

    - by Erin
    This might belongs on superuser but for me it's part of programming so i will ask it here. I find I use notepad to keep chunks of data that are important but not important enough to keep in my head. The one problem with this is I end up with a lot of files on my desktop that I don't know what they are for, or I don't save the file and my computer gets rebooted for some reason. So that big ramble leads to the question. I am looking for a note taking system that is light weight and easy to manage. I would rather it not be a huge application like onenote but if that is what you are using and is is working well for you could you explain how you are doing it? Thanks Erin.

  • Will Unity allow users to change the color/appearance of the top-Panel?

    - by Sam
    I'm very excited by the functional design principles and keyboard shortcuts that are being implemented for Unity. And function of use is more important to me than looks. However, after experiencing the aesthetic beauty of the display of the top panel in gnome-shell, I was wondering if users would be able to alter the color of Unity's top panel? IMHO it does not look as good as the gnome-shell implementation (or mac OS X/iPad). I think if an alternate color/appearance were chosen for the panel, it would make a big difference aesthetically. Is there a way to make it Black like gnome-shell? Or are the color choices limited to theme-designs as pointed out in this answer? For efficiency and clarity, the Panel should be better differentiated from application controls. The panel should be a different color because it has a "constant (always present) state," unlike application controls. For contrast and easy-recognition, I would like to make the Panel black (like gnome-shell) but make the application controls (e.g., those of Firefox) "Inverted"

  • How to Navigate Directly From One Table to Another in Word 2013

    - by Lori Kaufman
    Jumping to a specific page in Word is a common task and easy to do using the Find and Replace dialog box. You can also use this same tab to jump from one table directly to the next table in your document. Your cursor does not have to be in a table to jump to the next table. Put the cursor in any paragraph or table and press F5 or use the Ctrl + G keystroke combination to open the Find and Replace dialog box. The Go To tab is automatically selected. Select Table from the Go to what list and click Next. The next table in your document is selected and the Find and Replace dialog box stays open.

  • PHPForm Generate PDF Send to Email

    - by tom
    I'm a beginner in PHP I was wondering if this is easy to do or if i'd have to outsource this to a programmer - Basically when a user fills in the PHP Form and submits it I need this to generate as a PDF which will then email/attach to MY email and NOT the user who submitted this form. I have looked at tcpdf, fpdi but i dont think any of those scripts allow me to do this specifically as from what i heard it generates a download link for the user, and that is not what i need. If anyone can help me it would be greatly appreciated. Regards Tom

  • Realistic planetary terrain generation with weights

    - by Programmdude
    I need terrain generation for a planet. The planet will be divided up into several hundred hexes, and I need it to be realistic and based on weights. I have dabbled in terrain generation before, but nothing like this. So I figure it would be a good idea to ask the community for answers, recommended articles or the like. By realistic, I mean not just random hexes, but continent shaped things with a few islands. More desert around the equator and more ice around the poles. I also have two weights I need to base it around: ice percentage and water percentage. That means that around XX% of the planet will need to be water. Does anyone have any advice or places to start? Generating arbitrary terrain is easy, but something a bit more "organic" like this seems rather difficult. It also needs to be seamless. Should be obvious since it's a planet, but no harm in pointing it out.

  • When should I use AtomPub?

    - by Gary Rowe
    I have been conducting some research into RESTful web service design and I've reached what I think is a key decision point so I thought I'd offer it up to the community to get some advice. In keeping with the principles of a RESTful architecture I want to present a discoverable API, so I will be supporting the various HTTP verbs as fully as possible. My difficulty comes with the choice of representation of those resources. You see, it would be easy for me to come up with my own API that covers how search results are to be presented and how links to other resources are provided, but this would be unique to my application. I've read about the Atom Publishing Protocol (RFC 5023), and how OData promotes its use, but it seems to add an extra level of abstraction over what is (currently) a rather simple API. So my question is, when should a developer select AtomPub as their choice of representation - if at all? And if not, what is the current recommended approach?

  • How to disable three finger gestures on touchpad?

    - by oznah
    I am using 12.04 on a macbook pro. Everything works really well. I want to disable 3 finger gestures. It is way to easy to accidentally drag/move a window(3 finger gesture) while scrolling(2 finger gesture) when using a touchpad. I found this answer on ask ubuntu. It was marked answered but it is not. The functionality is still there. All this recommendation does is disable the drag marks on the window. This may be tricky because I want to disable 3 finger gestures but not 2 finger gestures. (ie I don't want to disable touchpad gestures all together)

  • Kiosk Mode Coding in Chromium

    - by Aaron
    I don't know how easy this would be, since I don't know anything about it, but I need an Ubuntu setup where the machine boots up, displays the login for a few seconds allowing a chance to log in as an admin, and then precedes to automatically log in to a user account which directly opens Chromium (any other browser is acceptable) in a kiosk mode where only the web content is visible, all Chromium keyboard shortcuts are disabled, and all but a select few websites are blocked, redirecting back to the home page after an "Unauthorized web page" warning comes up if the URL constraint is violated. Is it possible to code a kiosk setup like this, or am I asking for too much? If I'm simply uninformed, and there is already much documentation on anything like this, please redirect me to an appropriate page. If you can code or set up something like my description, please reply with step-by-step instructions, and instructions on how to modify the elements of the kiosk mode. Thank you in advance for any help. (Note: I'm currently using Ubuntu 10.04, but any distribution would work.)

  • How to Use the File History Feature in Windows 8 to Restore Files

    - by Taylor Gibb
    Jealous of your Mac OS X friends and their great Time Machine feature? Windows 8 has a new feature called File History that works much the same way, giving you an easy method to restore previous versions of your files. We are going to use a networked folder in for our article but you could always skip creating the network folder, and just use a USB drive. To use a USB drive you can just go to the setting for File History and turn it on, it should automatically find your USB and immediately start working.

  • Screen Scraping When All You Have Is A Hammer

            I had decided to create a list of what videos were already available on the Learning Pages of Silverlight.net.  When I clicked on the page for the entire list, however, I was quite daunted by the sheer number. I opened the source for the page, and found that there was an easy screen scraping [...]...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Light shaped like a line

    - by Michael
    I am trying to figure out how line-shaped lights fit into the standard point light/spotlight/directional light scheme. The way I see it, there are two options: Seed the line with regular point lights and just deal with the artifacts. Easy, but seems wasteful. Make the line some kind of emissive material and apply a bloom effect. Sounds like it could work, but I can't test it in my engine yet. Is there a standard way to do this? Or for non-point lights in general?

  • Making profit from a social network

    - by James P.
    This follows similar questions but I'd like to see if anything particular comes out of it due to the nature of site. In short, I've taken up the role of webmaster for a small social network site and wish to make it profitable to at least cover the running costs. The site is linked to a commerce and presents are offered to members according to the number of points they've accumulated through various actions. The site is running on shared hosting so it's probably dirt cheap but the presents can be expensive as a whole and some money has already been invested into the project. One idea I have is to seek some sponsors that would be willing to offer presents or special offers in return for publicity. I don't know if this will be easy or not. I'm also looking into adapting hosting to perhaps move static files to a cheaper online storage medium (see Ideas for reducing storage needs and/or costs (lots of images)). Other suggestions are welcome.

  • Animation file format

    - by Paul
    I'm trying to make a simple 2D animation file format. It'll be very rudimentary: only an XML file containing some parameters (such as frame duration) and metadata, and some images, each representing a frame. I'd like to have the whole animation (frames and XML document) packed in a single file. How do you suggest I do that? What libraries are there that would allow easy access to the files inside the animation file itself? The language I'm using is C++ and the platform is Windows, but I'd rather not use a platform dependent library, if possible.

  • How are you using the Managed Extensibility Framework?

    - by dboarman
    I have been working with MEF for about 2 weeks. I started thinking about what MEF is for, researching to find out how to use MEF, and finally implementing a Host with 3 modules. The contracts are proving to be easy to grasp and the modules are easily managed. Although MEF has a very practical use, I am wondering to what extent? I mean, is everyone going to be rewriting existing applications for extensibility? Yes, that sounds, and is insanely impractical. Rhetorically speaking: how is MEF affecting the current trends in programming? have you begun looking for opportunities to use MEF? have you begun planning a major re-write of an existing app that may benefit from extensibility? That said, my questions are: how do I know when I should plan a new project with extensibility? how will I know if an existing project needs to be re-written for extensibility? Is anyone using MEF?

  • Grams to Pounds: A Domino Chain Reaction [Video]

    - by Jason Fitzpatrick
    Most of us have seen a domino knock down or two in our day, but this demonstration video shows how a series of increasingly larger dominoes allow a tiny domino to knock over a 100 pound domino. A domino can knock over another domino about 50% larger than itself. A chain of dominos of increasing size makes a kind of mechanical chain reaction that starts with a tiny push and knocks down an impressively large domino. The only question we have after watching the video is: where can we find 29 appropriately sized dominoes? [via Neatorama] HTG Explains: What Is Windows RT and What Does It Mean To Me?

  • How can I convert an image from raw data in Android without any munging?

    - by stephelton
    I have raw image data (may be png, jpg, ...) and I want it converted in Android without changing its pixel depth (bpp). In particular, when I load a grayscale (8 bpp) image that I want to use as alpha (glTexImage() with GL_ALPHA), it converts it to 16 bpp (presumably 5_6_5). While I do have a plan b (actually, I'm probably on plan 'e' by now, this is really becoming annoying) I would really like to discover an easy way to do this using what is readily available in the api. So far, I'm using BitmapFactory.decodeByteArray(). While I'm at it. I'm doing this from a native environment via jni (passing the buffer in from C, and a new buffer back to C from Java). Any portable solution in C/C++ would be preferable, but I don't want to introduce anything that might break in future versions of Android, etc.

  • Five development tools I can't live without

    - by bconlon
    When applying to join Geeks with Blogs I had to specify the development tools I use every day. That got me thinking, it's taken a long time to whittle my tools of choice down to the selection I use, so it might be worth sharing. Before I begin, I appreciate we all have our preferred development tools, but these are the ones that work for me. Microsoft Visual Studio Microsoft Visual Studio has been my development tool of choice for more years than I care to remember. I first used this when it was Visual C++ 1.5 (hats off to those who started on 1.0) and by 2.2 it had everything I needed from a C++ IDE. Versions 4 and 5 followed and if I had to guess I would expect more Windows applications are written in VC++ 6 and VB6 than any other language. Then came the not so great versions Visual Studio .Net 2002 (7.0) and 2003 (7.1). If I'm honest I was still using v6. 2005 was better and 2008 was simply brilliant. Everything worked, the compiler was super fast and I was happy again...then came 2010...oh dear. 2010 is a big step backwards for me. It's not encouraging for my upcoming WPF exploits that 2010 is fronted in WPF technology, with the forever growing Find/Replace dialog, the issues with C++ intellisense, and the buggy debugger. That said it is still my tool of choice but I hope they sort the issue in SP1. I've tried other IDEs like Visual Age and Eclipse, but for me Visual Studio is the best. A really great tool. Liquid XML Studio XML development is a tricky business. The W3C standards are often difficult to get to the bottom of so it's great to have a graphical tool to help. I first used Liquid Technologies 5 or 6 years back when I needed to process XML data in C++. Their excellent XML Data Binding tool has an easy to use Wizard UI (as compared to Castor or JAXB command line tools) and allows you to generate code from an XML Schema. So instead of having to deal with untyped nodes like with a DOM parser, instead you get an Object Model providing a custom API in C++, C#, VB etc. More recently they developed a graphical XML IDE with XML Editor, XSLT, XQuery debugger and other XML tools. So now I can develop an XML Schema graphically, click a button to generate a Sample XML document, and click another button to run the Wizard to generate code including a Sample Application that will then load my Sample XML document into the generated object model. This is a very cool toolset. Note: XML Data Binding is nothing to do with WPF Data Binding, but I hope to cover both in more detail another time. .Net Reflector Note: I've just noticed that starting form the end of February 2011 this will no longer be a free tool !! .Net Reflector turns .Net byte code back into C# source code. But how can it work this magic? Well the clue is in the name, it uses reflection to inspect a compiled .Net assembly. The assembly is compiled to byte code, it doesn't get compiled to native machine code until its needed using a just-in-time (JIT) compiler. The byte code still has all of the information needed to see classes, variables. methods and properties, so reflector gathers this information and puts it in a handy tree. I have used .Net Reflector for years in order to understand what the .Net Framework is doing as it sometimes has undocumented, quirky features. This really has been invaluable in certain instances and I cannot praise enough kudos on the original developer Lutz Roeder. Smart Assembly In order to stop nosy geeks looking at our code using a tool like .Net Reflector, we need to obfuscate (mess up) the byte code. Smart Assembly is a tool that does this. Again I have used this for a long time. It is very quick and easy to use. Another excellent tool. Coincidentally, .Net Reflector and Smart Assembly are now both owned by Red Gate. Again kudos goes to the original developer Jean-Sebastien Lange. TortoiseSVN SVN (Apache Subversion) is a Source Control System developed as an open source project. TortoiseSVN is a graphical UI wrapper over SVN that hooks into Windows Explorer to enable files to be Updated, Committed, Merged etc. from the right click menu. This is an essential tool for keeping my hard work safe! Many years ago I used Microsoft Source Safe and I disliked CVS type systems. But TortoiseSVN is simply the best source control tool I have ever used. --- So there you have it, my top 5 development tools that I use (nearly) every day and have helped to make my working life a little easier. I'm sure there are other great tools that I wish I used but have never heard of, but if you have not used any of the above, I would suggest you check them out as they are all very, very cool products. #

  • Design pattern and best practices

    - by insane-36
    I am an iphone developer. I am quite confident on developing iphone application with some minimal feature. I would consider myself as a fair application developer but the code I write is not so much structured. I make vey little use of MVC because I dont seem to find places to impose MVC. Most of the time, I create application with viewcontrollers and very few models only. How could I improve the skill for making my code more reusable, standard, easy and maintainable. I have seen few books on design patterns and tried few chapters myself but I dont seem to skip my habit. I know few of them but I am not being able to apply those patterns into my app. What is the best way to learn the design patterns and coding habit. Any kind of suggestion is warmly welcomed.

  • HTG Explains: Photography with Film-Based Cameras

    - by Eric Z Goodnight
    We’ve become reliant on digital cameras since they are so easy to use. But have you ever wondered how film-based photography works? Read on to increase your photographic knowledge—or to develop an new appreciation for your point and click camera. Film-based cameras, to some, are a relic of the past. Simply an old technology made obsolete by the new and improved. But to many, film is an artisan’s material, and a photographic experience no digital system could hope to ever recreate. While many photographers, professional and amateur will swear by the quality of both film-based or digital cameras—the fact remains that film is still a valid way to take great photographs, and a fascinating way to learn more about how photography works.  HTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)What is a Histogram, and How Can I Use it to Improve My Photos?

  • How to publicize new Android's HTTP requests library

    - by Yaniv
    I don't know if this really belongs here, but I developed an open-source HTTP requests library for Android called Unite. This library was built mainly to significantly facilitate the work and coding time, and makes it easy to create and work with HTTP requests. I think a big advantage of this library is that it is open-source, so everyone can contribute to make it even better. I started this project for personal use, and I really like the result. What is the right and proper way to publicize the project, I do think it will be handy to Android developers. So how can I make developers know this library exist?

  • How can I work on a WordPress theme already installed in the root directory?

    - by Isaac Lubow
    I have WordPress installed at the root level of a website. I thought it would be easy enough to have a "coming soon" page called default.html and edit the .htaccess file as follows: AddHandler php5-script .php DirectoryIndex default.html index.php # BEGIN WordPress # END WordPress ...so that visitors to the site are sent to the default page, and I could manually specify index.php as my destination for testing. (This isn't a high-security job.) But index.php is redirecting me to the default page. When I remove the DirectoryIndex line, the index.php file is found automatically by visitors to the site root, but... that's the page I was trying to hide. What am I doing wrong with .htaccess and how can I get it to behave the way I want?

  • Which simple Java JPA ORM tool to use ?

    - by Guillaume
    What Java ORM library implementing JPA that match following criteria would you recommend and why ? free & open source alive (at least bug fixes and a mailing list) with good documentation simple (simpler than hibernate) I need to select a simple ORM tool that can be set up in minutes, without too much configuration and easy to understand, for setting simple CRUD DAOs. A query builder will be an interesting plus. Later I can have to move to Hibernate, that's why being JPA compliant is a must. I have found some candidates on the web, but not so much feedback, so I will gladly take your advices on the topic. ----- EDIT --------- I have been successfully testing ebean/avaje with a small test cases. Any one has a feedback on using these tools in production ?
