• How can I show contextual ads after a user filtered page contents by keyword?

  - by lex82

  I am building a social bookmarking service that is monetized in part by Google Adsense. However, I don't know how to influence how the ads are displayed. I think Google scans my pages and decides itself which ads to show where. Navigation on my site is mainly based on the selection of categories or tags being provided by the users. So after a user filters a list of bookmarks by the tag "SEO", I think I know pretty well what he is looking for. So I am looking for a service that allows me to show contextual ads for these particular keywords. How I can guide Google to show relevant ads? Can you recommend an alternative ad network, that gives me more control?

• Building Website with JAX-RS (Jersey)

  - by 0xMG

  Is it discouraged/not-common to build Websites (not web-services!) using Jersey or any other JAX-RS implementation ? I didn't find any guide/tutorial/article regarding that.. At first impression , it seems to me that building website using Jersey (with JSPs as Viewables) is easier and more efficient than using Servlets & JSPs. If anyone did it before , I will be pleased to get tips, Do's & Don'ts, best practices etc... And maybe a good tutorial.

• How to hide assets from user? ( e.g.: a png file )

  - by burninggramma

  I think the title is quite self-explaining, still this is a big area I think, so let me drop a few words: I've got a simple experiment game project going, and I want to make sure, that the user isn't messing with the game assets like player skin etc. In my opinion the best way would be that on production I would merge all the assets into one file and the application would check the hash of that file, so it could detect the corrupted data. Is this an acceptable practice? There must be sum libraries / applications which are targeting this problem, could you guide me on this? Project details: unix/linux, c++, sdl

• How to get started on working with WebTrends locally using a DEV account access? [on hold]

  - by Knowledge Craving

  I'm a newbie developer on WebTrends Analytics, although I have worked extensively on Adobe SiteCatalyst. Currently I want to integrate WebTrends with the web pages of a local project on my local JBoss EAP application server, so that I can run it locally and see how WebTrends work, along with how the Analytics reports show up. Later on, I may customize the reports data as per the project requirements. However, I can't find anywhere how I can start working on a local development process using a DEV account access. I'm mainly trying to get data on number of user visits per day, as of now, which will cater to multichannel experience. And later on, I will start pulling more data based on targeting and segmentation. Can anyone of you please help and guide me in the right direction? Any help is highly appreciated. Thank you!

• Info on UIDeviceFamily key in Info.plist

  - by dbv

  The iPad programming guide says I have to include the UIDeviceFamily key in Info.plist. It also says that the transitioning a target to iPad should have added the key. It didn't. I tried creating blank projects, both iPad-only and universal, and neither got that key. Google comes up short too. What's the story on this mysterious key? The simulator doesn't mind the fact it's missing.

• Change the width of Master in UISplitViewController

  - by Raj

  Hi, The iPad programming guide says that the splitView's left pane is fixed to 320 points. But 320 pixels for my master view controller is too much. I would like to reduce it and give more space to detail view controller. Is it possible by anyway? Edit: Link to the document which speaks about fixed width - http://developer.apple.com/iphone/library/documentation/General/Conceptual/iPadProgrammingGuide/UserInterface/UserInterface.html#//apple_ref/doc/uid/TP40009370-CH3-SW1 Thanks and Regards, Raj

• How does one actually use the UIRequiredDeviceCapabilities key?

  - by Andy

  I followed exactly what I thought I understood the steps to be in the iPhone Programming Guide for specifying that my app requires telephony (I opened MyApp-info.plist, added a new key called UIRequiredDeviceCapabilties, set the key type to Dictionary, added a new row with key set to "telephony", type Boolean, value YES), and sent my app off to Apple. Lo and behold, eleven days later, I get a message from Apple that it's been rejected for not using the UIRequiredDeviceCapabilities key. WTF? How are you actually supposed to implement this?
