• Codeigniter: how to track activity w/o using multiple db rows?

  - by Kevin Brown

  I need to track the completion of tasks for users. I started by having a row called "first_login", "profile_complete", "other_thing_complete", etc... I'd like to combine these all into one row "activity_state". I just don't know how to properly store data in this field, and how to retrieve it. What kind of field should it be, and how should I read/write to it?

• Adding a wrapper to an overloaded function

  - by Cev

  Say you had a timestamp function and then wanted to create a new function to combine your timestamp and Console.WriteLine(), e.g. public static void Write(string msg) { WriteTimeStamp(); Console.WriteLine( msg ); } But the WriteLine() method has 18 or so overloads, which will not be reflected in the signature of the wrapper function. How would you have the wrapper take non-strings and pass them on to WriteLine()?

• Java: Check if file is already open

  - by hello_world_infinity

  I need to write a custom batch File renamer. I've got the bulk of it done except I can't figure out how to check if a file is already open. I'm just using the java.io.File package and there is a canWrite() method but that doesn't seem to test if the file is in use by another program. Any ideas on how I can make this work?

• Find completely commented files which are commented by /* */.

  - by Dave

  Similar to this question. I would like to find all commented files. But in my case /* */ is a possibility. Apparently when you write changes to a database project, dropped objects are only commented out instead of deleting the file. I would like to remove all of these commented out files from the project. Is is possible to find all files which start with /* and end with */?

• Graph generation on iPhone

  - by Parrots

  Anyone have experience with drawing graphs on the iPhone? Looks like GraphKit isn't an option, so it's up to the programmer to either write his own library (using OpenGL, I guess), or an existing library. I can't seem to find any libraries that are confirmed to work on the iPhone. If you've written your own how did you go about it (opengl, quartz, etc), or if you used a library which one?

• Open x64 'SOFTWARE' registry key in C#

  - by Lance May

  I am trying to read the 64-bit HKLM\SOFTWARE registry key from a 32-bit (C#) application. This, of course, keeps redirecting my view to HKLM\SOFTWARE\Wow6432Node. According to what I've found this is doable, but I can't seem to find a .NET example anywhere. I just need to read; not write. Anyone ran across this before?

• Is there possible in clojure to make a deadlock (or anything bad case) using agents?

  - by hsestupin

  CLojure agents is powerful tool. So actions to the agents are asynchronously sent using functions "send" and "send-off". And in theory there couldn't appear something like deadlock. Is there possible to write some clojure code (for example invoking from some action another action to another agent) using agents in which we have some concurrency problem - it could be deadlock, race condition or anything else. (guys, i'm very sorry for my english)
