• Which way to make money on Android? ads, purchase, trial version?

  - by otakun85

  Hi, I want to release an app, but what is in your experience the best way to make money on android? I've seen some solutions out there, but which one is the best? Solution A: App is free and has ads. + long term income + free for customer ~ money based on usage - ads makes apps ugly - needs a internet connection, which your app may not need Solution B: App is purchased + instant income ~ money only once ~ the customer have only 15 minutes to try out the app - you need a credit card on the google market - the customer have to give money :D Solution C: Trial version Solution D: free Lite version with ads & full to pay version without adds Any other ideas?

• How can I pull data from PeopleSoft on demand?

  - by trpt4him

  I work in IT at a university and I'm working with about 5 different departments to develop a new process for students to apply to a specific school within the university (not the university as a whole). We're using a web-based college application vendor and adding the applicant questions for the school itself to the main university application. Currently the main application feeds into PeopleSoft. The IT staff here is building a new table to hold just our school's applicant data. I want to be able to access that data from PeopleSoft for use in external applications, but our IT staff doesn't really seem to understand what I'm requesting, as they simply tell me I can have access to the PS query tools. The problem is, I don't want to run just ad hoc queries, I want to be able to connect from outside PeopleSoft and show current data within the external app. I am unable to find documentation or get a clear answer to my question. Does PeopleSoft support access via a web services API or anything similar, and does that sound like the right direction for me to take?

• JET now available on OTN

  - by mramcha

  I know some of you have been waiting patiently, so I'm pleased to announce that the JET bundle is now available for download on the Oracle Technology Network. I've migrated most of the content from the old Sun wiki site, and got the download in a single handy location on OTN. Download JET now.  The version available is the current latest, which is 4.9.4. This version contains a number of updates, the most significant of which is the ability to specify slot locations instead of the traditional cXtYdZsN nomenclature. This is pretty useful when trying to Jumpstart multiple servers with SAS2.0 based HBAs, as they will have the WWN embedded in the cXtYdZsN name, and it's pretty difficult to guess what that will be until you've booted the server. The JetSDS and JetZFS modules have also been updated to use the slot terminology. Happy JETing,

• Content Weighting and Sociology

  - by Chris Massey

  I’ve had loads of fantastic feedback on the concept and early curation wireframes I posted on the labs, and it’s led to some further thoughts on the topic of voting. More specifically, thoughts about the kinds of behaviour and values a platform encourages in it’s users via the set of available actions. StackOverflow is a very good example of this kind of sociology in action, not only via the set of available actions, but through the reputation system it uses to both reward and control it’s users. In our case (specifically, in the case of the curation model I’ve been talking about thus far), the main considerations are how the quality of content is judged, and how to make sure each piece of curated content gets a fair hearing. Based on the feedback and conversations I’ve had with many of you over the last few days, a few considerations came to light about how we might need to weight and display our curations, and I’ve written about that more extensively over on the labs themselves – have a read and let me know what you think.

• Telerik OpenAccess ORM and the XML Metadata Source

  We all know that Telerik OpenAccess ORM has a completely new face with the Q1 2010 release so it is about time to start blogging about some of the features and improvements that the new Visual Designer brought along.  Today I will talk about one of the most notable changes in the new version of OpenAccess ORM and that is the XML only mapping. You all know that so far with the previous versions of the product the mapping information was defined by a mix of XML configuration files and CLR attributes. After a lot of customer feedback and thorough thought we decided to make the XML and the attributes as two separate and self-contained sources of metadata information about your model. You can choose one based on your personal preferences. I will start with a brief overview over the new XML mapping definition. Unlike previous versions, where all ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Changing AdWords campaign structure

  - by AlxVallejo

  I've been running a campaign for about a year and a half now and the campaign has been setup by location. I'd have one campaign targeted for a specific region. And then I would duplicate the ad groups for each campaign. I have 5 ad groups targeting different areas of my business). This has worked reasonably well. It just occurred to me that it might easier if the campaign structure were reversed: 5 campaigns: each campaign focused on a different area of business and divided into 20+ adgroups (based on location). Will this screw up my campaign if I switch the structure? I have 10's for QS and I don't want to lose that!

• @OnStart & @OnStop

  - by Geertjan

  In applications based on NetBeans Platform 7.2, you'll be able to replace all your ModuleInstall classes with this code: import org.openide.modules.OnStart; import org.openide.modules.OnStop; @OnStart public final class Installer implements Runnable { @Override public void run() { System.out.println("enable something..."); } @OnStop public static final class Down implements Runnable { @Override public void run() { System.out.println("disable something..."); } } } Build the module and the annotations result in named services, thanks to @NamedServiceDefinition: Aside from no longer needing to register the ModuleInstall class in the manifest, performance of startup will be enhanced, if you use the above approach: https://netbeans.org/bugzilla/show_bug.cgi?id=200636

• How much to charge for being available for support?

  - by Tvrdy

  I am working in small development firm, our main products are ASP.NET and SQL server based. We are deploying a new version of our product and client wants 4-hour response time technical support. Some of this support time will fall outside regular business hours and our boss asked us how much should we charge for being available outside regular business hours? Is it 50% of our hourly fee, 20% ? Any suggestion is appreciated, he is pushing us to speak up and I don't have any idea. I don't want to underprice my free time. Thanks.

• 2d engine with WebGL

  - by Philipp

  I am currently developing a HTML5 canvas game with a sprite-based 2d engine. The engine is working well so far, but now I thought that I could maybe add some cool graphic effects when I would re-implement the whole engine with WebGL. The whole graphic engine would stay strictly two-dimensional (think of it as a 3d world where the z coordinate of all vertices is 0.0). What I hope to gain from this is the ability to use pixel shaders to create special effects. I also think that the performance could improve. What do you think about that plan?

• Combining two MVC frameworks in a project

  - by SASM

  Is it any good to combine two MVC frameworks together in a project? Is it a fairly common approach? I am thinking about using a serverside framework like CodeIgniter/Laravel and client side framework AngularJS in a predominantly CRUD based web project. I am a bit apprehensive about this idea. I think this approach does not get the best out of both frameworks and can kind of get in way of each other making the application needlessly complicated. Are there some good approaches/practices if one wants to combine these frameworks together?

• Multiple parameters vs single parameter(object with multiple properties)

  - by Shwetanka

  I have an Entity Student with following properties - (name, joinedOn, birthday, age, batch, etc.) and a function fetchStudents(<params>). I want to fetch students based on multiple filters. In my method I have two ways to pass filters. Pass all filters as params to the method Make a class StudentCriteria with filters as fields and then pass the object of this class While working in java I always go with the second option but recently I'm working in php and I was advised to go with the first way. I am unable to figure out which way is better in maintaining the code, reusability and performance wise. Thanks.

• Search Result Organization

  - by Vecta

  I'm creating an AJAX live search on a website I'm working on. Users will select values from a few dropdowns and a list of products will be returned based on what they select. Some possible fields would be: color, model, make, etc. What type of organization of search results do users tend to find most useful? Is it better to lump them all together (alphabatized) or is it more useful to lump them together by make? In the past I've tended to group them by "make" but I'm not concerned that this will continually force some items with a make toward the end of the alphabet always to the bottom of the list. Any tips are greatly appreciated.

• Should we use python 2.6 or 2.7 or 3.x?

  - by lamwaiman1988

  The version of python which I am using is 2.6, and there is a 2.7 and 3.x. Usually I use python for some trivial program/snippet. I realize there are some major difference between 2.x and 3.x. I would really like to know, if I am going to make a bigger project with python, which version of python should I use? Should I upgrade to 2.7, or go to 3.x or stay with 2.6? The decision should be based on these terms: Number of user in the internet as a community. More users mean more open-source package and help from them. Functionality. Support from official development team. Compatibility for existing module/package. Thanks!

• DotNetNuke Page module - Silverlight Edition

  As part of the DotNetNuke Hackathon at the Capital DotNetNuke User Group on June 16th, I discussed using Silverlight to create rich DotNetNuke modules. The example that I presented was a work in progress which Ill be working on during the course of the Hackathon, even as participants are working on their own submissions. Youll be able to follow along with my progress over the next few days as I continue to flesh out the module. The module that I am working on is a Silverlight based replacement...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• RIA Services and Entity Framework POCOs

  WCF RIA Services contains a special domain service for entity framework which will automatically be used if you use the Domain Service template in Visual Studio. This winter I tried the template with a few projects. One of them had EntityObjects and the other had POCO entities. The EntityObjects worked great, but the POCO entities didn’t work at all. The bulk of the problems were based on the fact that the EntityDomainService used methods from the first version of Entity Framework that relied...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Online File Library

  - by janvdl

  I'm looking for a preferably PHP and web based system, to run on Ubuntu server. Basically it should be a "file forum" in the sense that users can register and be approved to post files to categories. Users with "read" privileges can then go through the categories and download files. Basically I sort of want a FTP-like system, but it should be as easy to manage users, categories, etc as that of a forum system like vB or phpBB. If it could have a forum look and feel that would also be great, but I don't want any discussions taking place.

• How do I swap two objects in C# (specifically Mono) without triggering GC?

  - by TenFour04

  I have two array lists. that I want to swap each frame. My question is, does the variable 'temp' need to be a member variable to avoid triggering GC, assuming this method is called on dozens of objects each frame? I'm not creating a new object, just a new reference to an object. public void LateUpdate(){ ArrayList<int> temp = previousFrameCollisions; previousFrameCollisions = currentFrameCollisions; currentFrameCollisions = temp; currentFrameCollisions.clear(); } I've been told there's no reason to make a primitive into a member variable just to avoid GC, so my best guess is that this also applies to object references.

• Using replacement to get possible outcomes to then search through HUGE amount of data

  - by Samuel Cambridge

  I have a database table holding 40 million records (table A). Each record has a string a user can search for. I also have a table with a list of character replacements (table B) i.e. i = Y, I = 1 etc. I need to be able to take the string a user is searching for, iterate through each letter and create an array of every possible outcome (the users string, then each outcome with alternative letters used). I need to check for alternatives on both lower and uppercase letters in the word A search string can be no longer than 10 characters long. I'm using PHP and a MySQL database. Does anyone have any thoughts / articles / guidance on doing this in an efficient way?

• HTML5 apps

  Right now nobody’s interested in a mobile solution that does not contain the words “iPhone” and “app” and that is not submitted to a closed environment where it competes with approximately 2,437 similar mobile solutions.Compared to the current crop of mobile clients and developers, lemmings marching off a cliff follow a solid, sensible strategy. Startling them out of this obsession requires nothing short of a new buzzword.Therefore I’d like to re-brand standards-based mobile websites and applications,...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Two different domain for specific languages pointing to one site

  - by user25599

  I developing a client's blog and he needs it to be bilingual (english and spanish). Now what he wants is that users can get to the content based on the domain e.g. Jhon enters www.domain.com and he gets the english version and Juan enters www.elsenordominio.com to get the spanish version. All content will be validated by php so the users and search engines only reads the domain related language. What do i need to use header re-direct or 301? is it bad for seo? will google will google penalize me? I hope you guys can help me and forgive me if my english is not good.

• Returning status code where one of many errors could have occured

  - by yttriuszzerbus

  I'm developing a PHP login component which includes functions to manipulate the User object, such as $User->changePassword(string $old, string $new) What I need some advice with is how to return a status, as the function can either succeed (no further information needs to be given) or fail (and the calling code needs to know why, for example incorrect password, database problem etc.) I've come up with the following ideas: Unix-style: return 0 on success, another code on failure. This doesn't seem particularly common in PHP and the language's type-coercion messes with this (a function returning FALSE on success?) This seems to be the best I can think of. Throw an exception on error. PHP's exception support is limited, and this will make life harder for anybody trying to use the functions. Return an array, containing a boolean for "success" or not, and a string or an int for "failure status" if applicable. None of these seem particularly appealing, does anyone have any advice or better ideas?

• How can I refactor my code to use fewer singletons?

  - by fish

  I started a component based, networked game (so far only working on the server). I know why singletons can be bad, but I can't think of another way to implement the same thing. So far I have: A GameState singleton (for managing the global state of the game, i.e. pre-game, running, exiting). A World singleton, which is the root entity for my entity graph An EntityFactory A ComponentFactory I'm thinking about adding a "MessageDispatcher" so individual components can subscribe to network messages. The factories do not have state, so I suppose they aren't so bad. However, the others do have global state, which is asking for trouble. How can I refactor my code so it uses fewer singletons?

• Random List of numbers in C

  - by Ant

  I have just started a C programming course and so far have only done the basics like printf, read a little on variables etc on the course book. The teacher has tasked us with writing a program that will take a value entered by the user, this will be the number of students in the class (25 at the moment but can be variable). It will then list the number of students randomly and place them in 3 columns. The purpose is to sort students into groups of 3 randomly, then display on the screen in columns. Now my question is not for the code that defeats the object of me attempting the exercise, but how to structure it. I can see that using an array can be used to display the list, but really after some pointers on how best to approach the problem in blocks, then I can attempt to program each block.

• Running the Ubuntu Kernel and OS on custom processor

  - by xupv5

  This is hardly a theoretical question as many have done this, albeit there's very little information on the underlying processes. I'm developing a custom MIPS-based processor on which I would like to run ubuntu. I'm quite baffled as to what to do next after you've designed the instruction set and the computer architecture itself. I need to be able to run a kernel and OS but how does it all tie in? At the moment I'm researching into designing a compiler for the linux kernel to generate the appropriate assembly language. Is that a good way to go? What do I need to do after that?
