• How can I force a preferred sound output device to be used?

  - by Dave M G

  In my sound settings interface, there are two devices for sound output: Both refer to the same physical device, which is a network sound device. Both work, but only with the second one, Simultaneous output to Kenwook Audio Device Digital Stereo (IEC958) on mythbuntu@mythbuntu, does the output volume respond to being changed. The first one always plays at the same level, and ignores volume settings. Every time I boot, the first one is selected. How can I make it so the second one is the default and the first one is disabled or at least never selected?

• 3D Modeling Software for Programmer [closed]

  - by Pathachiever11

  I've recently learned how to make games for Unity3d, and now I want to start making games! I can't wait to start! However, before I can make 3D games, I need to learn 3D modeling for character design, level design, and some animation. What is the easiest 3D modeling software, compatible with Unity3d? I do not want to spend too much time learning the software. From what I've heard, Blender is a bit complicated to use. Maya and 3dsMax seem very powerful. Could someone point me in the right direction? I don't want to spend a lot of time learning. I know its not that easy, but you guys have experience, you guys probably know out of all which one is easier and powerful. Could you recommend a software? Many Thanks!

• git in non-distributed, independent, lone programming ...best practice(s) ?

  - by explorest

  I am currently studying the git documentation to get a hang of distributed version control workflow and use of git command line. I want to first start using git with small, personal, pet projects so to gain experience before doing it on large scale (i.e., bigger projects, team dev). What areas of the git system should I, as a lone player, devote most of my study time to... what parts should I leave for the larger scale work later on. In other words what features of the git system will fully be grasped in team work only, and therefore should not be too involved with at an individual level?

• Spotlight on GlassFish 4.1: #6 Java API for WebSocket 1.1

  - by delabassee

  'Spotlight on GlassFish 4.1' is a series of posts that highlights specific enhancements of the upcoming GlassFish 4.1 release. It could be a new feature, a fix, a behavior change, a tip, etc. #6 Java API for WebSocket 1.1 JSR 356 (Java API for WebSocket) has recently passed the Maintenance Release ballot, this Maintenance Release fixes an important issue when Java SE 8 Lambdas are used (see here). GlassFish 4.1 will include an updated version of Tyrus (JSR 356 Reference Implementation) to bring the WebSocket API level to the latest version of the specification, i.e. WebSocket API for Java 1.1. It should be mentioned that the Tyrus version included in GlassFish 4.1 also brings additional features. Some of those will be highlighted in upcoming entries. https://blogs.oracle.com/theaquarium/resource/websocket_logo.png

• Webinar on Cross Platform Development with MonoTouch for the iPhone and Mono for Android on Wednesday

  - by Wallym

  The iPhone and Android are dominant in the marketplace. The two platforms currently have 85% of the smartphone marketplace and are continuing to grow that marketshare. Developers are being tasked with targeting these two platforms. In this session, we’ll take a high level look at how we can use c# and .NET knowledge to share code between iOS and and Android. We’ll look at linked files, using the Xamarin Mobile API, the challenges of running across platforms and frameworks, as well as other features of Visual Studio, Monotouch, MonoDevelop, and Mono for Android that allows us to write as much code that can run on both platforms.Here is the registration link: https://www302.livemeeting.com/lrs/8001676474/Registration.aspx?pageName=2w197495hzh0t56g

• Welcome to my first official full time employee!

  - by Vizioz Limited

  The last few months have been pretty manic and Vizioz has been growing successfully into a fully fledged development agency. I have been working with a couple of excellent off shore developers who I would like to publicly thank for all their hard work over the last couple of months!This week has been the start of a new era for Vizioz, I have taken on my first full time developer who is now based in our office in Reading, welcome to Colin. Which means we now have 3 Umbraco developers! Currently one with Level 2 qualification (me) but if business keeps growing I'll be sending the others for training shortly so hopefully by the end of the summer we'll be a certified solution provider.We have lots of plans for the next 6 months, so it should be exciting times, subscribe to my RSS feed to come along for the ride :)

• How to create realistic 2d lighting using colour temperature

  - by Truncheon

  I'm looking for a lighting algorithm that produces realistic lights expressed in kelvins, from about 2500k to 6500k. What I'm confused about is how to make the lights properly interact with the colors of game objects. If a whole level is fully lit (overcast daylight) then it would seem that I should use just the color of the object. But what if I'm in a closed room with no windows, and there is an incandescent bulb shining light in the room? How would that light properly light up the objects in the room? There does not seem to be an obvious solution to the problem. And simply mixing the color of the light with the colors of the object, seems an inaccurate approach.

• Windows Server, SQL Server [on hold]

  - by user136329

  I will give high level details of my requirement. We have one web application which accesses the database through SYBASE. The following technologies being used. Visual Studio 2010 .NET frame work 4.5 and for reporting Crystal Report. These are housed on windows server 2008. And for Database we use different servers. We are thinking of moving to SQL Server to be able to utilize the reporting features. My question is does SQL Server can be part of Windows Server 2008 R2 or we needed to have additional server for SQL?

• 55 and counting: ADF and Forms sessions at Oracle World

  - by Grant Ronald

  There is a phenomenal agenda of Forms, ADF and JDeveloper running at Oracle World this year.  So far, I can see about 55 sessions which are directly related to my product areas (Forms, JDeveloper and Oracle ADF).  These range from high-level strategic keynotes, to deep dives and hands on sessions from some of the best known names in ADF and Forms.  As we get nearer the kick off date I'm going to call out a number of these sessions but if you are considering whether OracleWorld is a good way of spending your training dollars my answer would be an emphatic YES!

• Max Brightness in ubuntu lower when compared to windows

  - by sklingel

  I've installed Ubuntu 14.04 on my (new) ThinkPad Edge330. Everything worked quite well so far. I've noticed that the screen wasn't that bright and was a bit disappointed of the ThinkPad, but then I realized that the brightness was much better on a parallel windows 7 installation I did later on. I already used this tip: Max brightness on NetBook I did increase the brightness to an acceptable level (could be the actual max. brightness, or is there a way to increase it even further?) But now unfortunately I cannot change the screen brightness at all anymore. Not by using the FN keys or in the system settings.

• Algorithms for rainfall + river creation in procedurally generated terrain

  - by Peck

  I've recently become fascinated by the things that can be done with procedurally terrain and have started experimenting with world building a bit. I'd like to be able to make worlds something like Dwarf fortress with biomes created from meshing together various maps. So first step has been done. Using the diamond-square algorithm I've created some nice hieghtmaps. Next step is I would like to add some water features and have them somewhat realistically generated with rainfall. I've read about a few different approaches such as starting at the high points of the map, and "stepping" down to the lowest neighboring point, pooling/eroding as it works its way down to sea level. Are there any documented algorithms with this or are they more off the cuff? Would love any advice/thoughts.

• Case convention- Why the variation between languages?

  - by Jason

  Coming from a Java background, I'm very used to camelCase. When writing C, using the underscore wasn't a big adjustment, since it was only used sparingly when writing simple Unix apps. In the meantime, I stuck with camelCase as my style, as did most of the class. However, now that I'm teaching myself C# in preparation for my upcoming Usability Design class in the fall, the PascalCase convention of the language is really tripping me up and I'm having to rely on intellisense a great deal in order to make sure the correct API method is being used. To be honest, switching to the PascalCase layout hasn't quite sunk in the muscle memory just yet, and that is frustrating from my point of view. Since C# and Java are considered to be brother languages, as both are descended from C++, why the variation in the language conventions? Was it a personal decision by the creators based on their comfort level, or was it just to play mindgames with new introductees to the language?

• Advice for transitioning into a Java developer position from doing other types of web development?

  - by Rick

  I've been doing web programming and currently work at a company working with mainly PHP and Javascript. For a little while now I've been becoming more and more frustrated with the shortcomings of this type of development and want to move to a company with a more defined development process that values doing things the "right way" such as using Unit tests, dependency injection / IoC, etc. I've been learning JEE / Java as much as I can on my own time but would really like to make a switch to doing this as my career and leave behind the PHP world altogether. I'm just wondering if anyone can give me advice on which things to put my main focus on right now to make myself marketable as an entry level Java developer. Basically, I feel that I'm not really learning anything new at my current job that will benefit me and its only making me more and more frustrated so I figure if there is any way to position myself for a transition I would rather do it sooner than later. Thanks for any advice.

• What's the current best practice for C multithreading?

  - by Dexter

  I've been a Java (and PHP) developer for most of my life, but will need to use C for my next project. I remember some basic stuff we did back in school with fork, pthread, semaphores, etc. but I'm not sure if that's still the "way to go" here, or if there have been any recent developments/improvements etc. Google's results seem to be fairly dated. Or does that just mean that this is still the current "state of the art"? Or will I have to use a (system-independent) libary like glib if I want higher-level abstractions, like synchronized queues? What other libraries are there? (The programm will only have to run on Linux though)

• Why is it always "what language should I learn next" instead of "what project should I tackle next"?

  - by MikeRand

  Hi all, Why do beginning programmers (like me) always ask about the next language they should learn instead of asking about the next project to tackle? Why did Eric Raymond, in the "Learn How To Program" section of his "How To Become A Hacker" essay, talk about the order in which you should learn languages (vs. the order in which you should tackle projects). Do beginning carpenters ask "I know how to use a hammer ... should I learn how to use a saw or a level next?" I ask because I'm finding that almost any meaningful project I'm interested in tackling (e.g. a web app, a set of poker analysis tools) requires that I learn just enough of a multitude of languages (Python, C, HTML, CSS, Javascript, SQL) and frameworks/libraries (wxPython, tkinter, Django) to implement them. Thanks, Mike

• Mock Objects for Testing - Test Automation Engineer Perspective

  - by user9009

  Hello How often QA engineers are responsible for developing Mock Objects for Unit Testing. So dealing with Mock Objects is just developer job ?. The reason i ask is i'm interested in QA as my career and am learning tools like JUnit , TestNG and couple of frameworks. I just want to know until what level of unit testing is done by developer and from what point QA engineer takes over testing for better test coverage ? Thanks Edit : Based on the answers below am providing more details about what QA i was referring to . I'm interested in more of Test Automation rather than simple QA involved in record and play of script. So Test Automation engineers are responsible for developing frameworks ? or do they have a team of developers dedicated in Framework development ? Yes i was asking about usage of Mock Objects for testing from Test Automation engineer perspective.

• Having tried differen ways but none worked - How do I disable a service from auto-start at boot in Ubuntu?

  - by Howard Guo

  This really doesn't make sense. I've been using many other distros and never had such difficulty managing autostart services. I found three ways of disabling autostart services, and none of them works for me: update-rc.d -f service_name remove chkconfig --level 12345 service_name off sysv-rc-conf I tried all the three ways to disable mysql daemon, mongo daemon, redis server, cups daemon, yet all of the utilities confirmed that the daemons are disabled, yet they still automatically start on boot. Please suggest the most correct way to disable services from auto-start at boot. Thank you! btw, it's running 12.04

• How to perform simple collision detection?

  - by Rob

  Imagine two squares sitting side by side, both level with the ground like so: A simple way to detect if one is hitting the other is to compare the location of each side. They are touching if all of the following are false: The right square's left side is to the right of the left square's right side. The right square's right side is to the left of the left square's left side. The right square's bottom side is above the left square's top side. The right square's top side is below the left square's bottom side. If any of those are true, the squares are not touching. But consider a case like this, where one square is at a 45 degree angle: Is there an equally simple way to determine if those squares are touching?

• Basic use of Business Rules

  - by shinynewbike

  I have a query on whether the following requirements would need to be designed via Business Rules - this is for a JEE based application where currently this is coded as part of the Business logic. System will create a tax account for every city, county and district combination that imposes tax for only certain cities, counties or districts depending on the taxpayer's business. When the user establishes an account which exists in all subdivisions (i.e. at city or county level), the application must use his tax code and automatically populate all the locations without requiring the user to data enter every location. I assume this would mean a data lookup table from a master table (of tax accounts) and fetch and display all locations. Is there some way in which a Rules Engine can be used to manage these combinations?

• Is there a point to writing in C or C++ instead of C# without knowing specifically what would make a program faster?

  - by user828584

  I wrote a small library in Python for handling the xbox 360's STFS files to be used on my web applications. I would like to rewrite it for use in the many desktop programs people are writing for 360 game modding, but I'm not quite if I should continue using C# or delve into C++ or even C. STFS is an in-file file system used by the xbox 360 and the job of the library would be extracting/injecting files, which could take noticeable amounts of time to do. What I know in C# comes from internet tutorials and resources, as would anything I learn about C++, so what I'm asking is if it's better to bring myself to a slightly lower-level language without knowing beforehand the features of the language that increase performance, or continue assuming that compiler optimizations and that my lack of experience will mean that the language I choose won't matter.
