• Release Notes for 11/28/2012

  This week we wrapped up a set of work to improve the actions and navigation within the project tabs. Now each tab in a project has a more consistent interaction experience. The navigation and filter activities are on the left side and action based links on the right. For example, on the Issue Tracker tab, the Basic and Advanced filters are on the left and the ability to create a new issue and subscribe the project are on the right.   Have ideas on how to improve CodePlex? Please visit our suggestions page! Vote for existing ideas or submit a new one. As always you can reach out to the CodePlex team on Twitter @codeplex or reach me directly @mgroves84

• Are keyboard layouts inherently flawed for programmers?

  - by Craige

  Lately I've been noticing my keyboard usage more and more and how it affects my productivity. It brought to mind a question/problem that I believe has not been truly solved in the programming community (partially based on individual preferences). Are all/most keyboard layouts inherently flawed for programmers? What changes to your keyboard layout do you feel would increase your productivity most? Edit Remember when answering that there are a number of different factors that could make a keyboard layout flawed. For instance, if you type as fast as you believe you need to, but hitting common keys is uncomfortable, said keyboard layout could be considered flawed.

• API design and versioning using EJB

  - by broschb

  I have an API that is EJB based (i.e. there are remote interfaces defined) that most of the clients use. As the client base grows there are issues with updates to the API and forcing clients to have to update to the latest version and interface definition. I would like to possibly look at having a couple versions of the API deployed at a time (i.e. have multiple EAR files deployed with different versions of the API) to support not forcing the clients to update as frequently. I am not concerned about the actual deployment of this, but instead am looking for thoughts and experiences that others have on using EJB's as an API client. How do you support updating versions, are clients required to update? Does anyone run multiple versions in a production environment? Are there pro's cons? Any other experiences or thoughts on this approach, and having an EJB centric API?

• How to modify VBO data

  - by Romeo

  I am learning LWJGL so i can start working on my game. In order to learn LWJGL I got the idea to implement the map builder so I can get comfortable with graphics programming. Now, for the map creation tool I need to draw new elements or draw the old one's with different coordinates. Let me explain this: My game will be a 2D scroller. The map will be consisting of multiple rectangles ( 2 strip triangles). When I click my left-mouse button i want to start the rectangle and when I release it I want to stop the rectangle bottom-right at that position. As I want to use VBOs I want to know how to modify data inside the VBO based on user input. Should i have a copy of a vertex array and then add the whole array to the VBO at each user input? How is usually implemented the VBO update?

• SDL2 with OpenGL -- weird results, what's wrong?

  - by ber4444

  I'm porting an app to iOS, and therefore need to upgrade it to SDL2 from SDL1.2 (so far I'm testing it as an on OS X desktop app only). However, when running the code with SDL2, I'm getting weird results as shown on the second image below (the first image is how it looks with SDL, correctly). The single changeset that causes this is this one, do you see something obviously wrong there, or does SDL2 have some OpenGL nuances I'm unaware of? My SDL is based on changeset dd7e57847ea9 from HG (since then there is one "Allow specifying of OpenGL 3.2 Core Profile on Mac OS X" commit, not sure if that would help).

• Visiting China

  - by Bill Graziano

  This summer I had the chance to visit China.  My brother and his wife are living in China and teaching English.  I spent a little over two weeks in Shanghai, Suzhou and Yancheng.  During that time I wrote some detailed updates for family and a few close friends on the impressions of a good Midwestern kid visiting the Middle Kingdom. I dumped them all into one document, did a little editing and now they’re posted.  You can download it here.  Below you can see my futile attempts to eat using chopsticks and me posing as a tourist on Nanjing Road in Shanghai.  The only thing I can say about chopsticks is that I didn’t starve.

• Sharing unique links on social media vs SEO

  - by MJWadmin

  We're currently implementing a voucher system on our site which will allow our users to obtain a 25+% discount on certain products, provided they donate 10% of the purchase price to charity. We will offer the ability to share the discounts via social media in return for larger discounts to the sharer for each person who clicks through the link and buys an item. I understand that social links have SEO benifits, but this appears to be based on lots of people sharing the same link. If our voucher users share a unique link i.e. http://ourdomain.com/sipsfesdf rather than a fixed link http://ourdomain.com/product-name will we still receive the same benifts? Should we instead share something like http://ourdomain.com/product-name/sipsfesdf Thanks in advance.

• Seeking some advice on pursuing MS in CS from Stanford or Carnegie Mellon or Caltech

  - by avi

  What kinds of projects are given preference in top notch colleges like Stanford, Caltech, etc to get admission into MS programme in Computer Science? I have an average academic portfolio. I'm pursuing Btech from a not so popular university in India with an aggregate of 67%. I'm good at designing algorithms and possess good knowledge of core subjects but helpless with my percentage. So, I think the only way I can impress them is with my project(s). Can anyone please suggest me the kinds of projects that are given preference by such top level institutes? Could you please also suggest some good projects? My area of interest would be Artificial Intelligence or any application/software/algorithm design which could be of some help to common people. Or if you have any other random idea for my project then please share it with me. Note: Web based projects and management projects like lib management wouldn't be my priority.

• Canonical links for huge websites

  - by Florin

  Let's say I have 5 products that are identical but the product code, the product color specifications and the product image. The title, meta and description are identical (by the way the color is in a select form). I made 4 products link canonical to the 1 that is the master based on many factors. If the master becomes inactive or without a stock one product from the other 4 will become the new master and the rest will become canonical to it. The question is if that by becomeing master from canonical will the site suffer a penalty from Google or it will work just fine? What will Google think about this strategy?

• OpenGraph tags and HTML5 validity

  - by netmano

  I have a HTML5 based page, and I inculded the OpenGraph tags according to it's documentation. Also I checked with Facebook Debug, and it can parse the metadata. But when I use W3C Validator, it reports the OG tags as error: Attribute content not allowed on element meta at this point. <meta property="fb:admins" content="...." /> Attribute content not allowed on element meta at this point. <meta property="og:url" content="http://www...."> They are all in the <head>. I would need my page be "valid" HTML5 and OG tags, as well. Could you help me giving a hint how can it be achieved? UPDATE: The name version also invalid: <meta name='fb:admins' content=''>

• 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?

  Watching YouTube videos on the Wii just got a whole lot easier; YouTube’s native Wii app streamlines the process and cuts out the need for the Internet Channel browser.

The new YouTube Wii app sports a clean interface, simple Wiimote-based controls, and all the great YouTube content you can handle. The app is free but currently U.S. only. According to the press release, the app will be rolled out to other countries in the coming months.

• Formula for three competing heroes, each has one they can beat and one they're beaten by

  - by Georgiadis Abraam

  I am trying to design a game for a project I have, The main idea is: 3 Types of heroes 3 Stats per hero There are no levels involved so the differences must be located on stats. Fight logic - The logic of fight is that type1hero has good chances winning type2hero, type2hero has good chances type3hero and type3hero has good chances winning type1hero. For over a week I am trying to find a stats based formula that will allow me to fix this but I can't, I was meddling with numbers yesterday and it was decent but I can't extract the formula out of it. Could you please guide me or give me hints on how should I start creating formulas on a Non lvl game that fulfills the fight logic?

• Ogre3D : seeking advices about game files management

  - by Tibor

  I'm working on a new game, and its related level editor, based on Ogre3D. I was thinking about how i could manage the game files, knowing that Ogre use .mesh files for models, .material for materials/texture information etc... . At first i thought about a common .zip folder decompressed at runtime (the same way Torchlight and Ogre samples do). But this way the game assets become a monolithic archive, loading takes time, and could be difficult to eventually patch them. So, let's say i have a game object named "Cube" i want to load in my program. Going for modularity, what if i create a compressed file (using zlib compression routines) named Cube.extname, containing its sub-files Cube.mesh, Cube.material and so on ? Are there any alternatives or should i stick with compressed objects? PS: Just to clear things, the answer is unrelated to my program code, at the moment i'm using "resources.cfg" pointing to the OgreSDK media directory.

• Checking whether a specific key was pressed in enchantJS

  - by MxyL

  I am using enchantJS and would like to use the letters and numbers as well as numpad on a keyboard to do different things (eg: hotkeys). From this page http://users.csc.calpoly.edu/~foaad/enchant/guide/playerInput.html By default, enchant.js provides input listeners for six buttons: UP, DOWN, LEFT, RIGHT, A, and B. By default, the directions are bound to the arrow keys. Any of the six buttons may also be bound to any key with an ASCII value. We’ll address that later. So enchant provides the ability to bind keys to different input such as up, down, left, right...but how can I simply check whether the D or X key was pressed, and if so, perform certain actions based on that event?

• window borders, menu bar missing over VNC

  - by zacaj

  I'm running Ubuntu 14.04 with Unity and Gnome3, however I don't have a screen hooked up anymore. I have installed x11vnc and run it with "-create" so that it will create a new X11 session, however when I VNC to it, the menu bar, window borders, etc are missing, windows are ordered based on creation time, and cannot be resized. Now, I don't really care if I end up with Ubuntu or Gnome's window manager, as long as this doesn't mess up my normal desktop stuff if I should happen to hook a monitor up again, and I'm not even attached to x11vnc if someone can point me to a good complete tutorial using something else, but I've been trying vino and tightvnc and rdp and x11vnc is the only one I've managed to get this far.

• Open Source Shopping Cart Software

  - by Cecil

  Ive come into a bit of an issue lately regarding shopping cart software, and i would like some recommendations. I have been an OsCommerce developer for years now, and im finding alot of my clients are wanting updated looking backends ... OSC is fantastic, but the fact that its not being updated anymore and that its clunky and table based is taking up quite a bit of my time. I have built a few sites on Magento, and although it gives quite a good backend, it is the slowest shopping cart i have ever come across in my time, that and the fact that modifying it takes years, has convinced me not to use that again. So, i like any input as to what people are finding good in todays open source shopping cart software.

• When creating a new text file, should I add a .txt extension to its name?

  - by Agmenor

  When I create a new document aimed at containing only plain text, I am not obliged by Ubuntu to add a .txt extension to its name. It works indeed very well: gedit opens it without problem, understanding very well that it is only text. The only two pro arguments I have found from now on for adding an extension are 1/ interoperability with Windows systems and 2/ avoiding confusion with folders having the same name. Nevertheless those two arguments do not convince me at all. As a consequence, should I keep the reflex of adding an extension to files or not?

• Custom extensible file format for 2d tiled maps

  - by Christian Ivicevic

  I have implemented much of my game logic right now, but still create my maps with nasty for-loops on-the-fly to be able to work with something. Now I wanted to move on and to do some research on how to (un)serialize this data. (I do not search for a map editor - I am speaking of the map file itself) For now I am looking for suggestions and resources, how to implement a custom file format for my maps which should provide the following functionality (based on MoSCoW method): Must have Extensibility and backward compatibility Handling of different layers Metadata on whether a tile is solid or can be passed through Special serialization of entities/triggers with associated properties/metadata Could have Some kind of inclusion of the tileset to prevent having scattered files/tilesets I am developing with C++ (using SDL) and targetting only Windows. Any useful help, tips, suggestions, ... would be appreciated!

• What are the basic skills a beginner JavaScript programmer should have?

  - by Sanford

  In NYC, we are working on creating a collaborative community programming environment and trying to segment out software engineers into differing buckets. At present, we are trying to define: Beginners Intermediates Advanced Experts (and/or Masters) Similar to an apprenticeship, you would need to demonstrate specific skills to achieve different levels. Right now, we have identified beginner programming skills as: Object - method, attributes, inheritance Variable - math, string, array, boolean - all are objects Basic arithmetic functions - precedence of functions String manipulation Looping - flow control Conditionals - boolean algebra This is a first attempt, and it is a challenge since we know the natural tension between programming and software engineering. How would you create such a skills-based ranking for JavaScript in this manner? For example, what would be the beginner JavaScript skills that you would need to have to advance to the intermediate training? And so on.

• Developing OpenGLES2 apps for Ubuntu Software Center

  - by Bram

  I have a game for iOS and Android that I now want to port to Ubuntu. I plan to distribute it with Ubuntu Software Center. Preferrably for free with an in-app-purchase. My codebase is currently based on OpenGL ES2 and written in C++. I could rewrite to OpenGL, but having progammable shaders is a must. Fixed pipeline OpenGL will not suffice. Is there a feature in place that lets you specify OpenGL requirements in the Ubuntu Software Center? I want to make sure that only Ubuntu users with compatible hardware will be able to download my game. Any APIs I could use for getting a suitable OpenGL context, or am I expected to just use glx for this? Or is the use of GTK mandatory?
