• How can I decrease my C# learning curve? [closed]

  - by MSU

  I have been learning programming, mostly C# and .net stuff. And I have target to become a fulltime .NET developer. But I am feeling that learning Graph is very slow, I have been learning C# programming, doing some coding everyday, but how I can learn very fast and increase my skills rapidly? I know there should be a balance of coding and reading, as without reading I can't code and without coding I can't increase my skills. SO, I am requesting here suggesting from experts on how I bring more pace to my learning curve? I intend to give 4-6 hours daily for this and on weekends 10+ hours.

• Kinect office demo ideas

  - by Tedd Hansen

  I'm thinking of placing a Kinect (connected to a PC) in the office and have something fun on it. Just a small thing people can interact with. Basically I get a depthmap (image) and a color image from the Kinect which I can analyze and do stuff with. My limited imagination came up with: Count people passing by. Measure average width of people passing by. Some ball with physics people can play with. Audible alert when someone is walking too fast. Anyone have any good ideas? :)

• RPG level-experience formula [closed]

  - by Comy

  I want to make an RPG game and I would like an advice on how should I create my level-experience formula. I saw this formula http://rsdo.net/rsdonline/guides/Experience%20formula.html#PHP and I created a formula myself and I want to ask you which would be better. RuneScape rates My rates Level 2 - 83 xp Level 2 - 35 Level 3 - 174 xp Level 3 - 84 Level 4 - 276 xp Level 4 - 150 Level 5 - 388 xp Level 5 - 238 Level 10 - 1,154 xp Level 10 - 1,087 Level 100 - 14,391,160 xp Level 100 - 311,017 As you can see at level 100 RuneScape's xp is very big and my level 100 is equal with RuneScape's Level 61. Is it better if the xp grows very fast at one point or depends on how I make my game?

• Html Buttons with Triangles [migrated]

  - by Dmitry

  I'm looking for the simplest way of creating 'buttons' with bootom-central triangles as follows: |--------| | Text | |---\/---| By buttons/menu items I mean something which will will support atomic mouse behavior for the whole shape's region. No rounded corners just the shape itself. I saw plenty of websites doing thsese buttons lately, but now for some strange reason I couldn't find any. Ideally I'm looking for tutorial links or some general guidances, as the topic might be too big to be covered by one post. Technology scope wise - ideally I'm looking for Html5/Css3 solution. I don't care mouch about old IE support and I think Html5/css3 will give a slicker/more elegant solution. On the way forward I might need to add drop shadows, which is another argument in favour of css3. Thanks.

• How to achieve uniform speed of movement in cocos 2d?

  - by Andrey Chernukha

  I'm an absolute beginner in cocos2 , actually i started dealing with it yesterday. What i'm trying to do is moving an image along Bezier curve. This is how i do it - (void)startFly { [self runAction:[CCSequence actions: [CCBezierBy actionWithDuration:timeFlying bezier:[self getPathWithDirection:currentDirection]], [CCCallFuncN actionWithTarget:self selector:@selector(endFly)], nil]]; } My issue is that the image moves not uniformly. In the beginning it's moving slowly and then it accelerates gradually and at the end it's moving really fast. What should i do to get rid of this acceleration?

• How can I add the version of a file to the file name with Tortoise-SVN?

  - by Eric Belair

  I would like to start giving unique names to "cache-able" files - i.e. *.css and *.js - in order to prevent caching, without requiring changes to the web-server settings (as is currently done in IIS). For instance, let's I have a JavaScript file called global.js. Going forward I would like it to have the name global.123.js when revision 123 is checked in. This would also require the following: The previous version of the file - perhaps it was global.115.js - is removed when the file is deployed. All references to the file are updated with the new file name How do I go about doing this? What concerns do I need to consider?

• A good way to build a game loop in OpenGL

  - by Jeff

  I'm currently beginning to learn OpenGL at school, and I've started making a simple game the other day (on my own, not for school). I'm using freeglut, and am building it in C, so for my game loop I had really just been using a function I made passed to glutIdleFunc to update all the drawing and physics in one pass. This was fine for simple animations that I didn't care too much about the frame rate, but since the game is mostly physics based, I really want to (need to) tie down how fast it's updating. So my first attempt was to have my function I pass to glutIdleFunc (myIdle()) to keep track of how much time has passed since the previous call to it, and update the physics (and currently graphics) every so many milliseconds. I used timeGetTime() to do this (by using <windows.h>). And this got me to thinking, is using the idle function really a good way of going about the game loop? My question is, what is a better way to implement the game loop in OpenGL? Should I avoid using the idle function?

• 2d Ice movement

  - by Jeremy Clarkson

  I am building an top-down 2d RPG like zelda. I have been trying to implement ice sliding. I have a tile with the slide property. I thought it would be easy to get working. I figured that I would read the slide property, and move the character forward until the slide property no longer exists. So I tried a loop but all it did was stop at the first tile in an infinite loop. I then took the loop out and tried taking direct control of the character to move him along the slide path but I couldn't get it to move. Is there an easy way to do an ice sliding tile based movement in libgdx. I looked for a tutorial but none exist.

• How to fix the copy/paste-pattern?

  - by Lenny222

  Where i work, people (consultants) feel pressed to release features as fast as possible. So instead of spending too much time on thinking about how to do things the right way or because they don't want to break anything, code gets copied from different modules and modified. It's not easy to prevent this, since the code base is open to the whole company. Lots of people work on this. Now that the mess is there already, what is the best way to remove those redundancies without breaking too much?

• Using JDBC to asynchronously read large Oracle table

  - by Ben George

  What strategies can be used to read every row in a large Oracle table, only once, but as fast as possible with JDBC & Java ? Consider that each row has non-trivial amounts of data (30 columns, including large text in some columns). Some strategies I can think of are: Single thread and read table. (Too slow, but listed for clarity) Read the id's into ConcurrentLinkedQueue, use threads to consume queue and query by id in batches. Read id's into a JMS queue, use workers to consume queue and query by id in batches. What other strategies could be used ? For the purpose of this question assume processing of rows to be free.

• Are all languages basically the same?

  - by Anirudh

  Recently, i had to understand the design of a small program written in a language i had no idea about (ABAP, if you must know). I could figure it out without too much difficulty. I realize that mastering a new language is a completely different ball game, but purely understanding the intent of code (specifically production standard code, which is not necessarily complex) in any language is straight forward, if you already know a couple of languages (preferably one procedural/OO and one functional). Is this generally true? Are all programming languages made up of similar constructs like loops, conditional statements and message passing between functions? Are there non-esoteric languages that a typical Java/Ruby/Haskell programmer would not be able to make sense of? Do all languages have a common origin?

• How does affliate marketing work, technically?

  - by Ron Gonzales

  There are lots of companies like Commision Junction that let you sell other people's products for a commission. How do these programs work, technically? Ie, are you simply given a link to the product you want to sell with an embedded ID in the URL? Does it involve cookies somehow? Do you take the order yourself and forward the information to the actual supplier of the goods/services? And how do you know if the program or the 'affliate network' isn't ripping you off by not creditting you for a sale?

• Fastest way to run a JSON server on my local machine

  - by Mohsen

  I am a front-end developer. For many experiemnets I do I need to have a server that talks JSON with my client side app. Normally that server is a simple server that response to my POSTs and GETs.

What is the fastest and easiest technology stack for database and server in this case? I am open to use Ruby, Nodejs and anything that do the job fast and easy. Is there any framework (on any language) that do stuff like this for me?

• WSS 3.0 to SharePoint 2010: Tips for delaying the Visual Upgrade

  - by Kelly Jones

  My most recent project has been to migrate a bunch of sites from WSS 3.0 (SharePoint 2007) to SharePoint Server 2010.  The users are currently working with WSS 3.0 and Office 2003, so the new ribbon based UI in 2010 will be completely new.  My client wants to avoid the new SharePoint 2010 look and feel until they’ve had time to train their users, so we’ve been testing the upgrades by keeping them with the 2007 user interface. Permission to perform the Visual Upgrade One of the first things we noticed was the default permissions for who was allowed to switch the UI from 2007 to 2010.  By default, site collection administrators and site owners can do this.  Since we wanted to more tightly control the timing of the new UI, I added a few lines to the PowerShell script that we are using to perform the migration.  This script creates the web application, sets the User Policy, and then does a Mount-SPDatabase to attach the old 2007 content database to the 2010 farm.  I added the following steps after the Mount-SPDatabase step: #Remove the visual upgrade option for site owners # it remains for Site Collection administrators foreach ($sc in $WebApp.Sites){ foreach ($web in $sc.AllWebs){ #Visual Upgrade permissions for the site/subsite (web) $web.UIversionConfigurationEnabled = $false; $web.Update(); } } These script steps loop through each Site Collection in a particular web application ($WebApp) and then it loops through each subsite ($web) in the Site Collection ($sc) and disables the Site Owner’s permission to perform the Visual Upgrade. This is equivalent to going to the Site Collection administrator settings page –> Visual Upgrade and selecting “Hide Visual Upgrade”. Since only IT people have Site Collection administrator privileges, this will allow IT to control the timing of the new 2010 UI rollout. Newly created subsites Our next issue was brought to our attention by SharePoint Joel’s blog post last week (http://www.sharepointjoel.com/Lists/Posts/Post.aspx?ID=524 ).  In it, he lists some updates about the 2010 upgrade, and his fourth point was one that I hadn’t seen yet: 4. If a 2007 upgraded site has not been visually upgraded, the sites created underneath it will look like 2010 sites – While this is something I’ve been aware of, I think many don’t realize how this impacts common look and feel for master pages, and how it impacts good navigation and UI. As well depending on your patch level you may see hanging behavior in the list picker. The site and list creation Silverlight control in Internet Explorer is looking for resources that don’t exist in the galleries in the 2007 site, and hence it continues to spin and spin and eventually time out. The work around is to upgrade to SP1, or use Chrome or Firefox which won’t attempt to render the Silverlight control. When the root site collection is a 2007 site and has it’s set of galleries and the children are 2010 sites there is some strange behavior linked to the way that the galleries work and pull from the parent. Our production SharePoint 2010 Farm has SP1 installed, as well as the December 2011 Cumulative Update, so I think the “hanging behavior” he mentions won’t affect us. However, since we want to control the roll out of the UI, we are concerned that new subsites will have the 2010 look and feel, no matter what the parent site has. Ok, time to dust off my developer skills. I first looked into using feature stapling, but I couldn’t get that to work (although I’m pretty sure I had everything wired up correctly).  Then I stumbled upon SharePoint 2010’s web events – a great way to handle this. Using Visual Studio 2010, I created a new SharePoint project and added a Web Event Receiver: In the Event Receiver class, I used the WebProvisioned method to check if the parent site is a 2007 site (UIVersion = 3), and if so, then set the newly created site to 2007:   /// <summary> /// A site was provisioned. /// </summary> public override void WebProvisioned(SPWebEventProperties properties) { base.WebProvisioned(properties);   try { SPWeb curweb = properties.Web;   if (curweb.ParentWeb != null) {   //check if the parent website has the 2007 look and feel if (curweb.ParentWeb.UIVersion == 3) { //since parent site has 2007 look and feel // we'll apply that look and feel to the current web curweb.UIVersion = 3; curweb.Update(); } } } catch (Exception) { //TODO: Add logging for errors } }   This event is part of a Feature that is scoped to the Site Level (Site Collection).  I added a couple of lines to my migration PowerShell script to activate the Feature for any site collections that we migrate. Plan Going Forward The plan going forward is to perform the visual upgrade after the users for a particular site collection have gone through 2010 training. If we need to do several site collections at once, we’ll use a PowerShell script to loop through each site collection to update the sites to 2010.  If it’s just one or two, we’ll be using the “Update All Sites” button on the Visual Upgrade page for Site Collection Administrators. The custom code for newly created sites won’t need to be changed, since it relies on the UI version of the parent site.  If the parent is 2010, then the new site will look 2010.

• Aren't there compilers better at telling the programmer what's wrong in a code ?

  - by jokoon

  I have worked a little while with the Microsoft compiler from Visual C++ but I worked a long time with G++, and I remember often having bad times understanding what was wrong in my code with the former. Beside binary code generation and optimisation, I think this is a very important feature of a C++ compiler: giving the programmer a clue that makes him understand as fast as possible what is wrong with his/her code. I can understand some programmers understand programming as some sort of "competition" to make less errors, but to me that's a counter productive opinion. I once tried Clang compiler for C from the LLVM thingie, I didn't use it for a long time, but I was impressed on how explicit and easy to understand the error messages were. What are your experiences, and how do you think this matters ? Some WIP of C++ Clang: http://clang.llvm.org/cxx_status.html

• Fastest bit-blit in C# ?

  - by AttackingHobo

  I know there is Unity, and XNA that both use C#, but I am don't know what else I could use. The reason I say C# is that the syntax and style is similar to AS3, which I am familiar with, and I want to choose the correct framework to start learning with. What should I use to be able to do the most possible bit-blit(direct pixel copy) objects per frame. EDIT: I should not need to add this, but I am looking for the most possible amount of objects per frame because I am making a few Bullet-Hell SHMUPS. I need thousands and thousands of bullets, particles, and hundreds of enemies on the screen at once. I am looking for a solution to do as many bit-blit operations per frame, I am not looking for a general purpose engine. EDIT2: I want bit-blitting because I do not want to exclude people who have lower end video cards but a fast processor from playing my games.
