• How can I get started programming OpenGL on Mac OS X?

  - by Michael Stum

  I'm trying to start OpenGL programming on a Mac, which brings me into unknown territory on a lot of things. During the day, I'm a Web Developer, working in C# and before that in PHP and Delphi, all on Windows. During the night, I try to pick up Mac/OpenGL skills, but everything is so different. I've been trying to look for some books, but the OpenGL books are usually for iOS (tons of them out there) and the Mac Books usually cover "normal" application Development. I want to start simple with Pong, Tetris and Wolfenstein. I see that there are a bunch of different OpenGL Versions out there. I know about OpenGL ES 1&2, but I don't know about the "big" OpenGL Versions - which ones are commonly supported on 10.6 and 10.7 on current (2010/2011) Macs? Are there any up to date (XCode 4) books or tutorials? I don't want to use a premade Engine like Unity yet - again, I know next to nothing about any Mac development.

• How can I convince my company to move to MVC?

  - by guanome

  I currently write web apps using asp.net web forms and getting my company to move to another technology is like [insert funny line here]. I would really like to start writing apps using MVC, but they fear any type of change. How is the best way to convince/ease them into using MVC? I guess this can go for moving to any new technology. Update Decided to go the rogue developer route and just started using it. I recreated a small app in MVC and learned the ropes that way, and moved up from there.

• Setting up Developers Conference

  - by Darknight

  In our local city in the UK, there are as far as I am aware no developer conferences. I am confident that our region has many professional developers as well as many graduating students whom who really benefit from a conference. I would like to ask the following questions: What steps or advice would one take if the task was given to set up a local developers conference? What would the costing look like? (excluding building/hosting of website(s)) How would one build interest and promote this? How would I approach, Local Companies & Universities to collaborate with them? I'm not just aiming this question to users who may have experience in setting up such conferences (but are highly welcome). Rather how would you attack this if you was tasked with this?

• What is So Unique About Node.js?

  - by Adrian Shum

  Recently there has been a lot of praise for Node.js. I am not a developer that has had much exposure to network application. From my bare understanding of Nodes.js, its strength is: we have only one thread handling multiple connections, providing an event-based architecture. However, for example in Java, I can create only one thread using NIO/AIO (which is non-blocking APIs from my bare understanding), and handle multiple connections using that thread, and I provide an event-based architecture to implement the data handling logic (shouldn't be that difficult by providing some callback etc) ? Given JVM being a even more mature VM than V8 (I expect it to run faster too), and event-based handling architecture seems to be something not difficult to create, I am not sure why Node.js is attracting so much attention. Did I miss some important points?

• Terminology For Web Development and General Programming/Software?

  - by Zenph

  EDIT: I should clarify. THe particular terms I listed below I fully understand. I also understand w3schools doesn't have the greatest information. These are just examples. I don't expect everybody to understand what an example is, but I hope the majority do. Does anybody have any resources listing terms related to programming and web development, or care to pitch in? Things like: Runtime Build time Framework Library Normalize I'm primarily a PHP developer so anything about that. I really am looking for general terms and specific terms related to web development, PHP, SQL, CSS, HTML. Appreciate any input. Couple I found: http://www.w3schools.com/site/site_glossary.asp http://docs.roxen.com/pike/7.0/tutorial/fundamentals/concepts.xml

• StreamInsight Licensing

  I cannot help but think that this is currently wrong.  There are two editions of StreamInsight (SI), Premium and Standard.  A link to their differences is here Points to note Developer Edition and Evaluation Edition represent Enterprise Edition in SQL Server but not SI where they represent Datacentre Edition.  Won’t this be confusing when people evaluating SI find that it is not the same animal when they move to Enterprise Edition? If SI Premium is the only thing you want out of the SQL Server box then it is going to be a high cost. The latency rates as well quoted on the site above make Premium Edition essential if you are going to be using this to do Real-Time analytics.

• What are the most important programming skills you need to improve as a team Leader or project manager?

  - by Aba Dov

  I decided to ask this question after I read the valuable answers to the great question What is the single most effective thing you did to improve your programming skills? and after attending Ad Burns "Secrets of a rock star programmer". It made me think about me and what programming skills I try to improve. I came to realize that there should be a difference in the programming skills you try to improve as developer and the programming skills you should improve as a team leader or project manager. My question is: What are the most important programming skills you need to improve as a team Leader or project manager? What would you recommend to others that want to improve?

• What frameworks are available for cross device 2d game development?

  - by kim3er

  Hi, I'm about to embark on a 2D gaming project. Initially, I'll be targeting iPhone and Facebook, but would like to expand the rollout to include Android (and possibly Windows Phone) in a future phase. Flash and Unity seem to be the most likely suspects, but is one better than the other? Are there pros/cons that may not be obvious at first glance? Are there frameworks that I have not considered? I am primarily a .NET developer, so the Unity C# integration is appealling. But I also have experience with AS3, JavaScript and Objective-C. Rich

• Java-Powered Robot Named NAO Wows Crowds

  - by Tori Wieldt

  He drew a crowd where he went at JavaOne. And only being 22.5 inches/573 mm tall, that's pretty impressive. Nao (pronounced now) is an autonomous, programmable humanoid robot developed by Aldebaran Robotics, a French robotics company. Over 200 academic institutions worldwide have made use of the robot. In this video from JavaOne, Nicolas Rigaud shows off the NAO robot which you can control with Java. We are eager to see what Java developers can do with a robot that can walk, talk, see, hear, and dance. &amp;amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;amp;gt; You can see several pictures in the blog Aldebaran Robotics at JavaOne.

• How many developers do I need to build a website like Freelancer.com in about 3-5 months? [closed]

  - by Sam

  I have been asked to make a list of people that I need to build something similar to freelancer.com. Not exactly same, has a few more features to it too but I can't really get my head around the whole freelancer.com site. I have built a social networking site from scratch which is 70% of Facebook and 20% Google+ in about 5 months with raw PHP, JS, CSS and Ajax. I dont think it will take me more than a month or something to build the whole freelancer.com from scratch. Please suggest anything that should I pay attention to. I am thinking about: 2 php developers 1 mysql engineer 1 network/server engineer 1 graphics artist 1 UI developer Time frame: 20 days Is this a good estimation?

• Iterating selected rows in an ADF Faces table

  - by Frank Nimphius

  In OTN Harvest May 2012; http://www.oracle.com/technetwork/developer-tools/adf/learnmore/may2012-otn-harvest-1652358.pdf I wrote about "Common mistake when iterating <af:table> rows". In this entry I showed code to access the row associated with a selected table row from the binding layer to avoid the problem of having to programmatically change the selected table row. As it turns out, my solution only worked fro selected table rows that are in the current iterator query range. So here's a solution that works for all ranges public String onButtonPress() { RowKeySet rks = table.getSelectedRowKeys(); Iterator it = rks.iterator(); while (it.hasNext()) { List selectedRowKeyPath = (List)it.next(); //table is the JSF component reference created using the table's binding //property Row row = ((JUCtrlHierNodeBinding)table.getRowData(selectedRowKeyPath)).getRow(); System.out.println("Print Test: " + row.getAttribute(1)); } return null; }

• How to avoid being forked into oblivion by a more powerful contributor?

  - by Den

  As recently reported here: Xamarin has forked Cocos2D-XNA, a 2D/3D game development framework, creating a cross-platform library that can be included in PCL projects. However the founder of the project that was forked says: The purpose of the MIT license is to unencumber your fair use. Not to encourage you to take software, rebrand it as your own, and then "take it in a new direction" as you say. While not illegal, it is unethical. It seems that the GitHub page of the new project doesn't even indicate that it's a fork in a typical GitHub manner, opting for an easily-removable History section instead (see bottom). So my questions are: Was Xamarin's action and the way the action was done ethical or not? Is it possible to avoid such a situation if you are a single developer or a small unfunded group of developers? I am hoping this could be either a wiki question or there will be some objective answers grounded on modern OSS ethics/philosophy.

• 2D management game [on hold]

  - by Simon Bull

  Very newbie question but I have a game idea in mind. It will be 2d and data centric, like football manager. However I am struggling to find a platform that would suit. I am an experienced line of business developer so am happy to write code, but I would like a platform that does some of the leg work for me so was avoiding OpenGL. I would also like to be able deploy to iOS, android, windows and OS X. What are the options? To be more clear, the game is not a normal platform or shooter type game, so game maker is likely to be way too basic and unity seems a little over the top (though I am not sure if the GUI options would fit?). The majority of the game is more like business screens just displaying data and having buttons to click. Are there options for this type of game (May help to look at football manager)?

• Setting coding priorities

  - by dotnetdev

  Hi, In the dev shops I've worked in, nobody has ever mentioned "coding priorities". I read this in a book or site somewhere, and sets the expectation of what priority should be first in the code. In places where this is not specified, what should the first priority be? It may sound simple to say "do what the business need requires", but that could be at the expense of performance/maintainability. Many people say maintainability first, regardless, some say fulfill the need regardless. I am a young developer, so I am probably missing the point somewhere. Of course, programming is engineering and tough because you can never have the perfect solution. Thanks

• How to build a .Net app which runs on desktop and as a Windows Service

  - by Mike

  Ok, I hope this is not too much confusing (with my poor English). I want to build a small .Net 4.0 app which monitors several other applications on a Windows Server OR on a regular Windows PC. It will have a WPF GUI with a variety of graphical controls. The app will be used in the following scenarios: If installed on a PC it should run as a “normal” single Windows desktop app If installed on a Server, it should run as a Windows Service. To use/manage the app it must have the same WPF GUI as in scenario 1 and the GUI should be run on the Server or on a remote PC At the moment I consider to write the application logic and connect it to the WPF GUI using a self-hosted WCF Data Service IN BOTH SCENARIOS. Since I’m not a pro developer I suppose it’s possible that I've missed something ;-) Will this work? Are there other/better solutions? Any answer or comment is highly appreciated.

• A good course on HTML/CSS/JS/UX worth it in part time?

  - by zengr

  I am a java/ruby developer from the last 3yrs, trying my hands on JS now. I am fascinated by the awesome UI designs these days. Any app I make, the worst aspect is the UI and I suck at it. I end up copying a design and with a crappy one. I am a student in San Jose, CA, and will be working from next month on Java most probably. My questions are: Are there any good courses (in the the colleges in silicon valley) on web Design (Photoshop), html, css, JS? Is it worth it?

• Code to simulate a users actions, such as logging in

  - by Gortron

  I've recently begun working on a PHP application, replacing another developer. I believed the application was using an API to communicate with a remote service but when I looked through the code I found that it was using a set of functions to actually log in, fill out forms and submit them as a user might do in a browser. My intention is to replace this code, to use the services API instead. I've considered leaving the code as is and not replace it. It makes me wonder though is this a common practice in the software industry? To have a programme simulate a users actions in a browser to perform a set of actions? It feels to me that this is clever but poor programming, Have any other developers seen this?

• Should I use parentheses in logical statements even where not necessary?

  - by Jeff Bridgman

  Let's say I have a boolean condition a AND b OR c AND d and I'm using a language where AND has a higher order of operation precedent than OR. I could write this line of code: If (a AND b) OR (c AND d) Then ... But really, that's equivalent to: If a AND b OR c AND d Then ... Are there any arguments in for or against including the extraneous parentheses? Does practical experience suggest that it is worth including them for readability? Or is it a sign that a developer needs to really sit down and become confident in the basics of their language?

• Creating an install of Ubuntu to clone

  - by naaronne

  I work on a team with several other developers. We all have similar hardware and we all run at least the same base development software. We are wishing to upgrade from 10.04 to 10.10 doing a clean install. I am looking for a way to do a base install of Ubuntu, including all our common applications, then clone it to each of the developers drives and then let them further customize their own install. Some considerations would be giving the developer the ability to have their own person id and not the same as which the base install was done with. I know they do this on VMware installs and corporate installs of Windows that can then be customized, but I have not seen this done with Ubuntu yet. Thanks
