• Restful route helpers using '.' instead of '/' in path

  - by dchua

  My path helpers (like data_path, users_path) are now translating itself to use '.' instead of '/'. For example, data_path(@data) translates to: data.%23<datareport:0x7fcaba0c2970> instead of '/data/id'. My routes look like: map.resources :data

• Creating a simple sencha listview using a loop

• Grails: GGTS not running on Amazon AWS EC2 anyone else successful?

  - by Anonymous Human

  Im just curious if anyone has had success trying to run the Groovy Grails tool suite on an Amazon AWS EC2 instance with its display exported into your windows machine. If so, I wanted to know which flavor of linux was used on the EC2. I am not having much success with it on the Amazon Linux but haven't tried their Ubuntu instances yet. I got all the way to getting GGTS installed and getting the display exported but when I launch GGTS I get log errors about libraries missing. This is most likely because I didn't use yum to install it so I am probably missing dependencies but I didn't have a choice its not offered as a yum package. Here are my log file errors when I try to launch GGTS: !SESSION 2014-06-08 03:08:04.873 ----------------------------------------------- eclipse.buildId=3.5.1.201405030657-RELEASE-e43 java.version=1.7.0_55 java.vendor=Oracle Corporation Framework arguments: -product org.springsource.ggts.ide Command-line arguments: -os linux -ws gtk -arch x86_64 -product org.springsourc e.ggts.ide !ENTRY org.eclipse.osgi 4 0 2014-06-08 03:08:12.116 !MESSAGE Application error !STACK 1 java.lang.UnsatisfiedLinkError: Could not load SWT library.

• Why should I use a thread vs using a process?

  - by danmine

  I'm a newbie at this so please forgive me for my ignorance. Separating different parts of a program into different processes seems (to me) to make a more elegant program then just threading everything. In what scenario would it make sense to make things run on a thread vs separating the program into different processes? When should I use a thread? Edit: Anything on how (or if) they act differently with single core and multi core would also be helpful.

• Manually Increasing the Amount of CPU a Java Application Uses

  - by SkylineAddict

  I've just made a program with Eclipse that takes a really long time to execute. It's taking even longer because it's loading my CPU to 25% only (I'm assuming that is because I'm using a quad-core and the program is only using one core). Is there any way to make the program use all 4 cores to max it out? Java is supposed to be natively multi-threaded, so I don't understand why it would only use 25%.
