• Problems With Eclipse and Ruby Plugin

  - by Jesse J

  I installed Eclipse and then the Ruby Development Tools (RDT), but it would crash when I try to alter certain features, like having line numbers, how far back to have history, and the code coloring scheme didn't work fully. I decided to try to uninstall Eclipse by doing sudo aptitude remove eclipse and then sudo aptitude install eclipse but instead it installed it back with the broken Ruby plugin. I also tried aptitude purge but that didn't help either. How can I freshly reinstall eclipse and get a properly working Ruby plugin?

• How do I determine whether I am going "forward" or "backward" through my History in GWT?

  - by Stephen Cagle

  I am looking at History and History JavaDocs in GWT and I notice that there is no way to tell whether the forward or backward button was pressed (either pragmatically or by the user). The "button press" is handled by your registered addValueChangeHandler, but the only thing passed to the handler is a string on your history stack. There is no indication as to whether the "History" is moving "back" (using the back arrow button) or "forward" (using the right arrow button). Is there any way to determine this?

• Need unicode characters in UITableView from SQLlite database

  - by Lee Armstrong

  I have some NSString varibales that incude items like Ð and Õ and if I do cell.textLabel.text = person.name; and if it contains one of those characters the cell.textlabel is blank! I have discovered that if I use NSString *col1 = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 0)]; To pull my data back it pulls back null, however using the deprectared method NSString *col1 = [NSString stringWithCString:(char *)sqlite3_column_text(compiledStatement, 0)]; Shows the characters! Any ideas?

• How to number the ls output in unix?

  - by Snehal

  I am trying to write a file with format - "id file_absolute_path" which basically lists down all the files recursively in a folder and give an identifier to each file listed like 1,2,3,4. I can get the absolute path of the files recursively using the following command: ls -d -1 $PWD/**/*/* However, I am unable to give an identifier from the output of the ls command. I am sure this can be done using awk, but can't seem to solve it.

• Javascript: achieving the Google Ad AJAX effect

  - by johnnietheblack

  I need to create a portable script to give to others to implement on their websites that will dynamically show content from my database (MySQL). I know AJAX has a cross-site problem, but it seems that Google's ad's somehow manage the effect in a cross-browser / cross-site fashion. Knowing that I have to give people a simple cut/paste snippet to put in their website...how can I achieve this? How did Google?

• Soap Web Service PHP

  - by James Radford

  Is it possible to send a complexType to a SOAP web service by creating the complexType locally, i.e. create the type by creating a class and then sending the instance of that class back to the service? Admittedly this is only possible if I can get the definition of the type from the service provider. I'm looking to send a complexType back to a web service. So if this approach wont work please suggest an alternative...

• How Have You Implemented Open Source Contributions At Your Company?

  - by Travis

  Ok guys, I know others have asked this question in a similar manner in the past, but I want to go beyond the theoretical and find out answers from people who have worked in an environment that relied heavily upon open source technology and never contributed anything back to the open source community, and was able to convince the boss / owner to contribute back to the open source community. I know alot of the standard answers, but I'm looking for some more practical information? What was the key argument, that changed the culture in your company, and how has it changed?

• Is there an easy way to stream a m3u in iPhone?

  - by marty

  I can have a UIWebView with the .m3u file opened, which will go to the webview with a play button displayed, and that automatically goes to the quicktime player and starts playing the stream. But when I press the done button, it goes back to the UIWebView with a little play button in the middle, and from there you can go back to the previous screen (it was selected from a tableview). So I just want it to automatically load the quicktime player in the view. How can I do that?

• iPhone SDK: Know when tab on Tab Bar is clicked?

  - by Nic Hubbard

  I have a tab bar which displays different views when clicked. When you click a tab for the first time, it calls the viewDidLoad method. But, it only calls that the first time. Is there a method that is called when a user clicks back to that tab, since the viewDidLoad won't be called that second time? (I need to do this to update a UITableView when the user clicks back to a tab)
