    errors tutorials
    I am giving a LaTeX course and have the idea to let the students find and solve problems within a few documents. Basically they shall learn how to create minimal examples and read error messages.However currently I have no document with ‘typical’ errors around.If someone has such examples from himself or within this forum I would like to have the code or link. It does not matter if its short or long. It should just be enough to let the students play with it for some minutes.

    Where can I learn how to do simple 2d animation well? Or is it really just literally drawing every single frame of something in photoshop? Is there tips or tricks? Tutorials to help get started?Also, what software options are there (preferably open source or even just free)?

    actionscript-3 tutorials
    Basically, I am either having trouble understanding how to use SharedObjects correctly, or I am not properly referencing a variable (from a seperate class from which it is defined) within a SharedObject, and I think the latter is my problem, although I’m not sure. When my character dies, my game goes to a game over screen, where I create 2 variables within a SharedObject: the bestScore (user’s all-time best score in the game) and then a tutorialBoolean (which will determine if the tutorial shows

    ruby-on-rails ruby activerecord tutorials
    I’m an absolute beginner to Ruby on Rails; I literally started last night. I’m following the Getting Started with Rails tutorial, although I’ve made a few modifications. Instead of a blog with posts and comments, I’m making a simple task-tracking application in which Projects have Tasks associated with them.Everything was going quite well until step #9 (Deleting Comments). According to the tutorial, I should be able to get the parent model for a comment by calling comment.post, the analogue o

    android tutorials
    Updated: I have now included the logcat file below.

I have been able to get all the “Layout” samples

    Am I missing something here?I follow the instructions exactly on this page (and some of the other tutorials) but they always seem to be missing some key information as they don’t work out of the box.I added a bunch of packages that seemed like were missing, but now I’m stuck.http://developer.android.com/resources/tutorials/views/hello-gridview.htmlDescription Resource Path Location Type Conversion to Dalvik format failed with error 1 HelloGrid Unknown Android Packaging ProblemAn
