• What license (eg. BSD, GPL, etc) can I use for an open source app that can be used commerically, for free?

  - by Pure.Krome

  Hi folks, I've got an application on Codeplex. It's based on some other free open source code which comes with a BSD license. As such, people keep asking if they can use my open source code/library in their commercial apps. I want them to be able to, provided they give credit to the source app (the project which i based my code, from .. and that has the BSD license) and also my code. They can take my code and do whatever (fork it, etc).. Just make sure they give credit, of course. So - what license could I use? Currently, I've set it to be GPL .. so is that ok? NOTE: Yes yes, I know that any answers are not from a lawyer and it's just all personal thoughts and I need to consult a special lawyer if I want some professional advice, etc. etc. I'm happy to take that risk, here.

• Part-time Programming Job

  - by Bluechip Solutions

  I am a student at Middlesex Universtity, London studying Information Technology. I really love software development and I have taught myself how to write HTML + CSS, JavaScript (I use jQuery and AngularJS) and Java (I learnt this in school). I have developed few apps (a desktop app in Java and a mobile app with AngularJS and PhoneGap) I am looking at applying for a part-time programming job to develop myself. Are there part time jobs available for someone like me and are my skill set enough to get me a job? I understand this topic may not be ideal here but this is the only place I know can provide me answers. Thank you!

• Program not running from expected directory?

  - by twpc

  I am working on a web-based program, using Java. I am not sure exactly how to phrase this, but I expect the program to be running from within the c:/Resin/webapps/apps directory. However, when I reference a file in the program like this: "../files/randomfile.pdf", it cannot find that file. It works when I reference it like this: "c:/Resin/webapps/files/randomfile.pdf". How to I change the "running location"? (And what is the technical term for this?)

• PHP Framework Benefits / Downfalls

  - by Lizard

  I have been a PHP developer for about 10 years now and until about a month ago I have never used a framework. The framework I am now using due to an existing codebase is cakePHP 1.2 I can see certain benefits of the frameworks with the basic helpers like default layouts. I can definitely see the benefits of MVC keeping the logic separate etc. But the query building just seems to be bloated. Is this expected? Am I likely to be able to build better queries than the framework could build? I just feel I could get my apps running better without a framework. What are your thoughts?

• Are there predifined styles for making arrow buttons in windows phone 7?

  - by Micah

  I want to make some buttons in my app that look like the common round buttons with the arrows found all over the win 7 apps. Anyone know where I can find resources for these? UPDATE Here's a great tutorial on creating round buttons in WP7. This is exactly what I was trying to do, but I will use the images mentioned by John Gardner below: http://blogs.msdn.com/b/priozersk/archive/2010/08/13/creating-round-button-for-wp7-part-1.aspx http://blogs.msdn.com/b/priozersk/archive/2010/08/14/creating-round-image-button-for-wp7-part-1.aspx Thakns!

• BlackBerry - Multiple Screens or Single Screen with Content Manager?

  - by Max Gontar

  Hi! I've seen projects which use many screens each one for different layout and functionality. I've seen projects with only one screen (like wizard workflow) where content is changed on user interaction (and this seems to be logical to use single screen in wizards). But also I've seen projects (apps like game or messenger or phone settings utility) which use single screen for different functionalities. I can see such advantages of having single screen in app: keep same decoration design and menu or toolbar (which may be also achieved with inheritance) keep single screen in ui stack (which may be achieved by pop/push screen) easy to handle data over application Can you tell other advantages/disadvantages of single screen app? When its better to use this approach? Thank you!

• Length of text that can just fit into one screen without scrolling

  - by KailZhang

  I find some iphone book apps have such feature: One screen one page of text without scrolling. The text can just fit into the whole screen with linebreaks and indentations. I'm curious of how to implement this. How could I decide the length of text that just fit into the screen. And also, given the whole text, I can calculate out the number of pages. If this is not possible to be done on iPhone(runtime?), then is it possible to process the text before storing it in app? I mean I calculate how many pages I need(how to split the raw text), probably how many lines per page.

• How much Java should I have learnt before trying Android programming?

  - by Sidney Yin

  Hi - I have been seeking beginner learning books in Android, and of course found out that I should learn Java first. So I began studying Java and now I am quite comfortable with objects, classes, inheritance, interfaces, and just moved onto Layouts in Swing as well as Swing Features. But I am starting to wonder.... do I know enough about Java now? Can I start programming Android yet? Of course I can keep going in Java, but have been itching to begin programming Android apps. Any definitive answer here about how much Java I need to know before Android? Thanks so much!

• "Refreshing" an XML feed on iPhone/Mac OSX

  - by Steve

  Hi all, I'm curious for those of you who are building iPhone apps based on REST/SOAP/XML-RPC or simply pulling down a dynamic XML feed, what does it mean exactly to you when a user says 'refresh' the feed? The straight forward way is to populate some collection, say an NSMutableArray, with whatever you bring down from the feed. If a widget on the UI is available to refresh, I typically do something like: [myMutableArray removeAllObjects]; // follow steps to repopulate myMutableArray It seems this is the least efficient algorithm for refreshing an XML feed. For instance many folks who are building Twitter clients, are appending changes to their existing feed, versus bringing down the entire feed in its complete form again. What kind of algorithms are you using to "refresh" your models when speaking to a server-side data source? Thanks all.

• Should I use C(99) booleans ? ( also c++ booleans in c++ ?)

  - by Roman A. Taycher

  I haven't done much c programming but when I do when I need a false I put 0 when I want true I put 1, (ex. while(1)), in other cases I use things like "while(ptr)" or "if(x)". Should I try using C99 booleans, should I recommend them to others if I'm helping people new to programming learn c basics(thinking of cs 1?? students)? I'm pretty sure the Visual Studio compiler supports c99 bools, but do a lot of projects (open source and c apps in industry) compile for c89? If I don't use C bools should I at least do something like #define TRUE 1 #define FALSE 0? Also what about c++ Booleans (for c++)?

• How does android communicate with dynamic services?

  - by ezekielweb

  I am trying to develop an app and I want it to bring in data from a mySQL database. But from some reading I have done on different sites, I am realizing that it is probably not going to happen. But I am curious to know, how do apps like PhoneFlix and others view that dynamic data on the application? Does it somehow just bring it in through http? If so, how would I go about doing that? Does anyone know of any good sites that will point me in the right direction? Thanks ezekielweb

• iPhone real memory climbs when interacting with UI

  - by Scott Gress

  I've been using the Activity Monitor to check the memory usage of my iPhone apps. I've noticed that the Real Memory climbs whenever I interact with the UI in any way, even if there's no code being called. For example, I can create a brand new View-Based application and run it, and as I click or drag in the empty window the Real Memory increases even though the app isn't responding in any way. I get that the view controller is doing some stuff in the background to interpret my interactions, but it seems like the memory should go back down after a second or so. Instead, it keeps going up and up and up as long as I keep clicking or dragging. I can wait forever and it never decreases. This is a little disturbing. Am I missing something?

• Utilizing a third party application for GitHub in a django project

  - by Smock

  I'm trying to use a third party application located here: git://github.com/Star2Billing/django-audiofield.git I'm using Aptana Studio as my IDE. I created my project and then I clicked on the project and imported the app from the github location. It looked like it imported. I wanted to check that it imported properly before beginning any real coding so I performed manage.py validate. I got a message that stated: "No module named audiofield". I added the app to my Installed Apps settings and followed the installation instructions. I'm not sure if I'm importing it incorrectly. Also, I'm using virtualenv in Aptana. I'm not sure if this may have added to the problem. Please help.

• WPF MessageBox close without any action

  - by developer

  Hi, I have a confirmation message box for the user in one of my apps. Below is the code for that, MessageBoxResult res= System.Windows.MessageBox.Show("Could not find the folder, so the D: Drive will be opened instead."); if (res == MessageBoxResult.OK) { MessageBox.Show("OK"); } else { MessageBox.Show("Do Nothing"); } Now, when the user clicks on the OK button, I want certain code to execute but when they click on the red cross at the upper right corner, I just want the messagebox to close without doing anything. In my case I get 'OK' displayed even when I click on the red cross icon at the upper right corner. Is there a way I can have 'Do Nothing' displayed when I click on the cross. I not want to add any more buttons.

• Beginner's Language app

  - by Eiseldora

  Hi I'm a techie with no programing experience. I know html and css, but I'd like to someday be able to make an app for my phone (I have an android) and possibly mobile websites. I made learning a programing language and creating a mobile app a goal for my job, and now my boss would like me to pick a programing language to learn. I found a free open course from MIT (http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-00-introduction-to-computer-science-and-programming-fall-2008/) called introduction to computer science. In the course they teach python, but more importantly it seems they teach how to think like a programmer. When I told my boss about the free online course she didn't think that Python was an appropriate language for me to learn. She'd like me to learn a language that is more similar to one used to make Phone apps. Does anyone out there know a better language for me to pick up that would be similar to Android or iPhone's App language. Thank you

• Suspension of Gmail account [closed]

  - by Ifeanyi Agu

  I have a Joomla site with my gmail account (google apps) being used as the SMTP server for sending mails. I also have a newsletter component on this site. I tried sending newsletter to all my subscribers and I noticed that the SMTP server could not be connected to. I then checked the emails of my company and noticed that the one I used to set it up was suspended. I cannot really explain why Google suspended the email account. Please could anyone tell me if Google saw the mails that were being sent as spam.

• Best way to develop a secured application. With .net

  - by John S

  Hello, we are developing a windows application, and as most apps out there, there is a login form. What I don't like is that the login form validates the user and opens the main form if user and pass are correct. Simple as is. All the function calls etc are called without verifying the user and pass again, what should be the right thing to do. What's the best way to develop a secured application that if for any reason, the login form is by passed, the other function calls won't run? Some devs suggested that we include an user and pass params on each function, which seems to be wrong... thanks!

• What statistics app should I use for my website?

  - by Camran

  I have my own server (with root access). I need statistics of users who visit my website etc etc... I have looked at an app called Webalyzer... Is this a good choice? I run apache2 on a Ubuntu 9 system... If you know of any good statistics apps for servers please let me know. And a follow-up question: All statistics are saved in log-files right? So how large would these log-files become then? Possibility to split them would be good, dont know if this is possible with Webalyzer though...

• Shift from Java to c++

  - by zengr

  Hello, I have been developing applications based on C# (.net) and Java (J2EE) from the last 3 years. But, now I feel, Java, C# makes you lame (from learning point of view) and you can develop your apps quickly but you fail to understand the basic underlying concepts of programming. So, I am trying to learn C++, but I find it a little "confusing" due to pointer, multiple inheritance, some conventions and other concepts of C++ which don't exist in Java. So, what do you guys suggest? How should I got about it? Thanks PS: I am a student, so have all the time in the world and actually shift.

• Extending folder (LiveFolder?) class

  - by yamsha

  So, I noticed that I can organize apps into folders (HTC Incredible). However these folders are fairly limited in their capabilities. I want to implement an activity that extends the "base" folder activity (at the very least I want to add the ability to rearrange items in folders), but I can't figure out the class name... So, what's the name of the class that is used when adding a "New Folder" to the Home screen? PS I did take a look at the Android developer website. But the discussion there revolves mostly around content providers. I assume that's not quite what I need since I'd have to create a separate content provider for each new folder, or am I misunderstanding something?

• How can I update my business' Facebook page via my Ruby on Rails app?

  - by Eric S.

  I'm creating a new rails app for my business, and I just finished a new feature where I can put an announcement on the website (for specials, sales, etc.). I want this announcement to automatically be set to my business' Facebook page. How can I easily do this? Is the only way to create a Facebook application, and then if so, can a Facebook application have permissions to edit a business' page (I know apps can edit user profiles, but I don't know about business pages)? Thanks for any help!

• Dev Environment Tests Not 100% Compatible with Staging/Production in Rails

  - by aronchick

  We use a bunch of specific apps/APIs that (unfortunately) differ quite a bit from dev to staging/production. We use tests and continuous integration at each stage, but in dev, the tests fail annoyingly (throwing dialogs, etc - thanks Windows for the 64-bit notification!). I hate to write custom code, but are there some best practices for how to allow a subset of testing in ruby/rails - or for patching out specific tests when you're running on Windows? Some specific situations that: Identify.exe does not support 64-bit Windows and throws a dialog. Sethostname is not supported, and throws an error (at least it's command line).
