• Which open source PHP project has the 'perfect' OOP design I can learn from?

  - by aditya menon

  I am a newbie to OOP, and I learn best by example. You could say this question is similar to Which Scala open source projects should I study to learn best coding practices - but in PHP. I have heard-tell that Symfony has the best 'architecture' (I will not pretend I know what that exactly means), as well as Doctrine ORM. Is it worth it to spend many months reading the source code of these projects, trying to deduce the patterns used and learning new tricks? I have seen equal number of web pages dissing and liking Zend's codebase (will provide links if deemed necessary). Do you know of any other project that would make any veteran OOP developer shed tears of joy? Please let me add that practicality and scope of use is not a concern at all here - I just want to do: Pick a project that has a codebase deemed awesome by devs way better and greater than me. Write code that achieves what the project does. Compare results and try to learn what I don't know. Basically, an academic interest codebase. Any recommendations please?

• Netflix Updates Android Tablet App; iPad Update On The Way

  - by Jason Fitzpatrick

  Android: If you’re rocking an Android tablet, such as a Kindle Fire or Nook, you’ll want to update your Netflix app today. The new version sports a host of improvements including a massively overhauled interface. The old Netflix tablet application was functional but lackluster; it felt almost as if they didn’t realize they were designing it for a tablet. The new Netflix app is focused on beautiful cover-flow style navigation, displaying twice as many titles per screen, and an emphasis on natural navigation with finger swipes and taps. According to the Netflix press release, an iPad update will be rolling out in the next few weeks.

• A Cautionary Tale About Multi-Source JNDI Configuration

  - by scott.s.nelson(at)oracle.com

  Here's a bit of fun with WebLogic JDBC configurations.  I ran into this issue after reading that p13nDataSource and cgDataSource-NonXA should not be configured as multi-source. There were some issues changing them to use the basic JDBC connection string and when rolling back to the bad configuration the server went "Boom".  Since one purpose behind this blog is to share lessons learned, I just had to post this. If you write your descriptors manually (as opposed to generating them using the WLS console) and put a comma-separated list of JNDI addresses like this: <jdbc-data-source-params> <jndi-name>weblogic.jdbc.jts.commercePool,contentDataSource, contentVersioningDataSource,portalFrameworkPool</jndi-name> <algorithm-type>Load-Balancing</algorithm-type> <data-source-list>portalDataSource-rac0,portalDataSource-rac1</data-source-list> <failover-request-if-busy>false</failover-request-if-busy> </jdbc-data-source-params> so long as the first address resolves, it will still work. Sort of.  If you call this connection to do an update, only one node of the RAC instance is updated. Other wonderful side-effects include the server refusing to start sometimes. The proper way to list the JNDI sources is one per node, like this: <jdbc-data-source-params> <jndi-name>weblogic.jdbc.jts.commercePool</jndi-name> <jndi-name>contentDataSource</jndi-name> <jndi-name>contentVersioningDataSource</jndi-name> <jndi-name>portalFrameworkPool</jndi-name> <algorithm-type>Load-Balancing</algorithm-type> <data-source-list>portalDataSource-rac0, portalDataSource-rac1, portalDataSource-rac2 </data-source-list> <failover-request-if-busy>false</failover-request-if-busy> </jdbc-data-source-params>(Props to Sandeep Seshan for locating the root cause)

• How to set up an environment for android app development?

  - by The Dark Knight

  I have been researching for sometime now regarding the process to install android sdk and associated tools . After visiting Android Developers page, i first installed the android sdk and then installed eclipse plugins for my indigo version from the install softwares options.However, it is mentioned in the developers page : Download the Android SDK. Install the ADT plugin for Eclipse (if you’ll use the Eclipse IDE). Download the latest SDK tools and platforms using the SDK Manager. I have downloaded the sdk and installed the adt plugins for eclipse.I just need to point the eclipse towards the location of the sdk. However, i am stuck at the last step which is asking me to download the latest tools using the sdk manager. The manager interface pops up and i see a lot of options there. I don't know which ones i must select and install. If some one can help me out here and tell me which options to choose and install(if possible, with a screen shot), it will be very beneficial for me.

• Would it be possible to create an open source software library, entirely developed and moderated by an open community?

  - by Steven Jeuris

  Call it democratic software development, or open source on steroids if you will. I'm not just talking about the possibility of providing a patch which can be approved by the library owner. Think more along the lines of how Stack Exchange works. Anyone can post code, and through community moderation it is cleaned up and eventually valid code ends up in the final library. For complex libraries an elaborate system should probably be created, but for a simple library it is my belief this is already possible even within the Stack Exchange platform. Take a library of extension methods for .NET for example. Everybody goes their own way and implements their own subset of what they feel is important, open-source library or not. People want to share their code, but there is no suitable platform for it. extensionmethod.net is the result of answering this call for extension methods, but the framework hopelessly falls short; there is no order, or structure at all. You don't know whether an idea is any good until you try it, so I decided to create an Extension Methods proposal on Area51. I belief with proper moderation, it could be possible for the site to be more than a Q&A site, and that an actual library (or subsets of it) could be extracted from it. Has anything like this been attempted before? Are there platforms better suited for this?

• OpenSource license with commerial-use exemptions for the owner

  - by dbkk

  I'm looking for an open source license which grants me additional privileges. Features: Anyone can freely modify, fork, use the code, as long as they make their source changes publicly available. They can use it in other open source projects, but not in closed-source projects. Only I and entities I specifically designate can use the code as part of a closed-source application. I am also exempt from the duty to publish the source code changes. I'm not trying to forbid the commercial use, just to allow myself more flexibility to use the code, while still contributing to open source. I don't want to burn myself by being legally forbidden from using the libraries I wrote in my commercial projects. Large companies use such dual licenses to maintain an open source project, while also selling the premium version. Which licenses of this type are available? What caveats or obstacles exist?

• Android: how do I switch between game scenes in a game? Any tutorials?

  - by Flavio

  I am trying to create a simple game using the Android SDK without using AndEngine (or any other game engine). I have plenty of experience designing games from the past, but I'm having lots of trouble trying to use the Android SDK to make my game. By far my biggest hurdle right now is switching between views. That is, for example, going from the menu to the first level, etc. I am using a traditional model I learned (I think it's called a scene stack or something?) in which you push the current scene onto a stack and the game's main loop runs the top item of the stack. This model seems non-trivial to implement in the Android SDK, mostly because Android seems to be picky about which thread instantiates which view. My issue is that I want the first level to show up when you press a button on the main menu, but when I instantiate the first level (the level class extends SurfaceView and implements SurfaceHolder.Callback) I get a runtime error complaining that the thread that runs the main menu can't instantiate this class. Something about calling Looper.prepare(). I figured at this point I was probably doing things wrong. I'm not sure how to specifically phrase my issue into a question, so maybe I should leave it as either 1) Does anybody know a good way (or the 'proper' way) to switch between scenes in an Android game? or 2) Are there any tutorials out there which show how to create a game that doesn't take place entirely in one scene? (I have googled for a while to no avail... maybe someone else knows of one?) Thanks!

• What is the basic loadout for an open source web developer?

  - by DeveloperDon

  Thus far, I have mainly been an embedded developer, but I am interested in having the flexibility to do mobile and web development as well. I think my tools should include the following, but probably a lot more. LAMP stack. Java IDEs like Eclipse and IntelliJ. JS frameworks like Dojo, Node.JS, AngularJS, (is it better to mix or commit to one?). Cloud solutions like EC2 and Azure (again, ok to mix or better to commit to one?). Google APIs. Continuous integration server. Source control tools with Git for new work, SVN, CVS, +others for imports. FTP server. Unit test runners. Bug trackers. OOAD modeling tools or plug-ins? Graphic design tools? Hosting services. XML / JSON / other markup? Content management, SEO? I am also interested to know if there are tools where it might be better to mix, match, or support all available (maybe for source control) and others where the full focus should be on one (maybe Java vs. C# or Windows vs. Linux vs. MacOS). Perhaps some of these questions need context of whether the projects will be greenfield (just pick favorite) or maintenance (no choice, each project continues legacy, sometimes with a poor tools).

• How is Sencha Touch performing on Android in practice ?

  - by Vidar Vestnes

  Hi I'm just about to start a project using Sencha Touch, and just done some minor testing on my HTC desire device. All tutorial videos at Vimeo seems to be using an iPhone emulator running on a Mac. Im not sure how fast this emulator is compared to a real iPhone device or even an real Android device, but from what i have experienced, it seems that my HTC desire is not performing that nicly as this emulator. All animations (sliding, fading, etc) seems abit laggy. You can easily notice that the FPS is much less than on the Vimeo videos. HTC desire is a relativly new and modern Android 2.2 phone, running with decent hardware, so im wondering if Sencha Touch is "ready" for the Android platform. Anybody with practical experience with Android and Sencha Touch ?

• How to proceed when a bug in open source libraries is suspected?

  - by Suma

  We are using some open source libraries in our projects. Sometimes there are some issues found in some of them (most likely library bugs, but it may also be a wrong usage from our side, especially when sometimes documentation is not exactly 100 % complete). As the libraries are often quite complex, debugging them to pinpoint the source of the problem is sometimes quite hard. Can you help me to summarize what other options are there and how to exactly proceed with them? I have just recently hit some strange problems when using TCMalloc (Google scalable memory allocator) on Windows, so I would most welcome answers which would apply to this particular library, but more general answers are good as well. 1) Ask the maintainer/owner of the project for assistance. How can this be done? 2) Hire someone to identify and fix the issue. How to do this? How can I find someone with enough expertise in some particular library? ... any other options?

• Open Source Project all dressed up but nowhere to go...

  - by Calanus

  Over the past 2 years myself and a colleague have built an online statistical analysis application using a mixture of silverlight, wcf and R. I (a c# programmer) wrote all the silverlight and wcf stuff whilst my colleague (a statistician) came up with the stats algorithms and wrote the R code. Now we think that this app is fairly unique - a rich gui online statistics application that is much more intuitive than all the other online stat apps that I've seen. But despite this we don't really know where to go with the project, mainly for the following reasons: 1) Its fairly complicated stuff - without the mix of programing and stats skills it would be difficult for anyone to "get into" the project and contribute. 2) We are stalled by a lack of a proper place to host the site. Currently it sits on the family windows 7 media centre, not exactly the best place to host it as it could interfere with the missus trying to watch Corrie/Friends/Oprah etc. Soo, anyone got any ideas on how to move forward with this? I guess that my strength is programing not marketing so despite working hard at this for the past couple of years I feel that I've reached a dead end! Also, does anyone know of any free windows hosting for open source projects? If I could find a proper place to put the app I might feel re-energised about the whole thing. The source code is on codeplex at: http://silverstats.codeplex.com, whilst the app is currently hosted at http://silverstats.co.uk

• Is it worth moving from Microsoft tech to Linux, NodeJS & other open source frameworks to save money for a start-up?

  - by dormisher

  I am currently getting involved in a startup, I am the only developer involved at the moment, and the other guys are leaving all the tech decisions up to me at the moment. For my day job I work at a software house that uses Microsoft tech on a day to day basis, we utilise .NET, SqlServer, Windows Server etc. However, I realise that as a startup we need to keep costs down, and after having a brief look at the cost of hosting for Windows I was shocked to see some of the prices for a dedicated server. The cheapest I found was £100 a month. Also if the business needs to scale in the future and we end up needing multiple servers, we could end up shelling out £10's of £000's a year in SQL Server / Windows Server licenses etc. I then had a quick look at the price of Linux hosting for a dedicated server and saw the price was waaaaaay lower than windows hosting. One place was offering a machine with 2 cores for less than £20 a month. This got me thinking maybe the way to go is open source on Linux. As I write a lot of Javascript at work (I'm working on a single page backbone app at the moment), I thought maybe NodeJS and a web framework like Express would be cool to use. I then thought that instead of using SQL why not use an open source NoSQL database like MongoDB, which has great support on NodeJS? My only concern is that some of the work the application is going to do is going to be dynamically building images and various other image related stuff, i.e. stuff that is quite CPU heavy - so I'm thinking of maybe writing anything CPU heavy in C++ and consuming it as a module in Node. That's the background - but basically is Linux a good match for: Hosting a NodeJS/Express site? Compiling C++ node modules? Using a NoSQL DB like MongoDB? And is it a good idea to move to these unfamiliar technologies to save money?

• How do I create a game that runs on Windows, iOS and Android?

  - by AspaApps

  I use C++ to create windows games and now I want to step into another other OS like Android or iOS. I'm totally familiar with C++ so I tried to create app for iOS using objective C it was working awesome. However, I also want to publish games for Android but not by using Java. I don't want to create a single game 5-6 times for other platforms. Is their any way that if I create game for Windows then it will work in Android and iOS ? Or should I use Action Script 3.0? If I use action script 3.0, will it require Flash player to run the game in Windows, Android, iOS?

• Should I use my real name in my open source project?

  - by Jardo

  I developed a few freeware programs in the past which I had signed with my pseudonym Jardo. I'm now planning to release my first open source project and was thinking of using my full real name in the project files (as the "author"). I thought it would be good to use my name as my "trademark" so if someone (perhaps a future headhunter) googles my name, they'll find my projects. But on the other side, I feel a bit paranoid about disclosing my name (in the least case I could be getting a lot of spam to my email, its not that hard to guess your private email from your name). What do you think can be "dangerous" on disclosing your full name? What are the pros and cons? Do you use your real name or a pseudonym in your projects? I read this question: What are the advantages and disadvantages to using your real name online? but that doesn't apply to me bacause it's about using your real name online (internet discussions, profiles, etc.) where I personally see no reason to use my real name... And there is also this question: Copyrighting software, templates, etc. under real name or screen name? which deals with creating a business or a brand which also doesn't apply to me because I will never sell/give away my open source project and if someone else joins in, they can write their name as co-author without any problems...

• Is beginner knowledge of Java enough to develop for Android? [closed]

  - by teenCoder

  I just finished the book "Tech Yourself Java in 24 Hours, 6th Edition" I have an understanding of the language (by understanding I mean, the basics and everything covered in the book) and I have been experimenting and building little things with my knowledge. I want to learn about Android and was wondering if I need to increase my knowledge in Java before moving on to Android or can I just go straight to Android?

• Prevent auto mounting Android sdcard under Linux Mint

  - by BullShark

  I recently obtained an older Android phone, so that I could test Android Apps on it. I've needed it because I have a Nexus 7 but not older Android versions, hardware, etc. to test on. I'm having a problem with it under Linux Mint with Cinnamon. When I plug the phone in, or remove and plug the sdcard from the phone back to it while the phone is plugged in, Linux automatically mounts the sdcard. This is a problem because once it is mounted under Linux, it dismounts from the phone running Android 2.3.5, and I can no longer test Android Apps I write that require the sdcard to be present, writable. I went to Menu System Tools System Settings System Details Removable Media, and it brings up this window. I have changed the settings to always "Ask what to do" on "Select how media should be handled". However, the sdcard still gets mounted and then I am asked how I want to open these files (media players, photo importers, file browser, etc.). If I click the checkbox for "Never prompt or start programs on media insertion", then the sdcard is mounted, and I am not asked how to open these files. Eject is just a noob word for Ubuntu users that means umount (unmount) like "Adminstrator" is another ubuntu noob word for the root user. And if I unmount the sdcard, the phone doesn't recognize it again until I take the sdcard out and plug it back in. The phone sees it for a brief moment until Linux Mint takes it over. There are 2 possible solutions and maybe more: 1) Prevent Linux from automounting sdcards some how 2) Tell Android not to allow the computer it is plugged into to take over the sdcard, HOW? Edit: I found out how to prevent the sdcard from being automatically mounted: Now it gets recognized by Linux: bullshark@beastlinux ~ $ dmesg | tail -n 25 [597212.218323] sd 21:0:0:0: [sde] Attached SCSI removable disk [597212.218639] sr 21:0:0:1: Attached scsi CD-ROM sr2 [597212.218910] sr 21:0:0:1: Attached scsi generic sg7 type 5 [597217.139373] sd 21:0:0:0: [sde] 3862528 512-byte logical blocks: (1.97 GB/1.84 GiB) [597217.140726] sd 21:0:0:0: [sde] No Caching mode page present [597217.140735] sd 21:0:0:0: [sde] Assuming drive cache: write through [597217.143595] sd 21:0:0:0: [sde] No Caching mode page present [597217.143602] sd 21:0:0:0: [sde] Assuming drive cache: write through [597217.152240] sde: sde1 [597389.751008] 4:2:1: cannot get freq at ep 0x84 [597390.238742] 4:2:1: cannot get freq at ep 0x84 [597624.903132] sde: detected capacity change from 1977614336 to 0 [597637.677763] sd 21:0:0:0: [sde] 3862528 512-byte logical blocks: (1.97 GB/1.84 GiB) [597637.679616] sd 21:0:0:0: [sde] No Caching mode page present [597637.679626] sd 21:0:0:0: [sde] Assuming drive cache: write through [597637.682508] sd 21:0:0:0: [sde] No Caching mode page present [597637.682515] sd 21:0:0:0: [sde] Assuming drive cache: write through [597637.692758] sde: sde1 [597661.857979] sde: detected capacity change from 1977614336 to 0 [597688.775455] sd 21:0:0:0: [sde] 3862528 512-byte logical blocks: (1.97 GB/1.84 GiB) [597688.776814] sd 21:0:0:0: [sde] No Caching mode page present [597688.776823] sd 21:0:0:0: [sde] Assuming drive cache: write through [597688.780055] sd 21:0:0:0: [sde] No Caching mode page present [597688.780062] sd 21:0:0:0: [sde] Assuming drive cache: write through [597688.788639] sde: sde1 bullshark@beastlinux ~ $ However, the phone still unmounts the sdcard upon being detected by Linux.

• Programmatically creating scrollview(s) from custom component in android

  - by jaapbeetstra

  I'm trying to build a compound control in Android, containing (among other things) a ScrollView. Things go wrong when I try to view the control in Eclipse, crashing with a NullPointerException after the error message: "Parser is not a BridgeXmlBlockParser". Stacktrace: java.lang.NullPointerException at android.view.View.<init>(View.java:1720) at android.view.ViewGroup.<init>(ViewGroup.java:277) at android.widget.FrameLayout.<init>(FrameLayout.java:83) at android.widget.ScrollView.<init>(ScrollView.java:128) at android.widget.ScrollView.<init>(ScrollView.java:124) at android.widget.ScrollView.<init>(ScrollView.java:120) at my.compound.control.StringPicker.onMeasure(StringPicker.java:46) ... I've traced the error to the following conditions: The NPE is thrown because a Context.obtainStyledAttributes() call returns null when the attrs argument passed is null. This only applies to the BridgeContext implementation used in Eclipse, which expects attrs to be an instance of the BridgeXmlBlockParser. The attrs argument is null because I create the ScrollView using the (Context) constructor. There is a workaround of course, which is passing the attrs I receive when Eclipse constructs the compound control, but I don't want all the attributes set on the compound control to apply to my inner control. Am I doing something wrong, is this a bug in Android Eclipse, ...?

• Android SeekBar Minimum and Continuous Float Value Attributes

  - by fordays

  I'm looking for a way to implement a minimum value in my SeekBar and also have the option to increment decimal numbers. For example, currently my SeekBar's minimum is set to 0, but I need it to start at the value 0.2. Also, I would like to have the functionality to be able to have the user select a number from 0.2 to 10.0 at a .1 precision so they can choose the numbers 5.6 or 7.1. Here are the style attributes for my SeekBar: <style name="SeekBar"> <item name="android:paddingLeft">30dp</item> <item name="android:paddingRight">30dp</item> <item name="android:layout_width">fill_parent</item> <item name="android:layout_height">wrap_content</item> <item name="android:layout_marginTop">0dp</item> <item name="android:layout_marginBottom">0dp</item> <item name="android:max">10</item> <item name="android:progress">1</item> </style>
