You can use the `initWithData:` initializer:

    [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];

Change the encoding to that of the source data.

I&#39;m running a couple of standard Fedora instances on EC2. I feel the public hostnames of the instances assigned by Amazon are too weird and hard to remember. I&#39;d like to change them to something short (like red/blue/green/etc).

Is there any draw back in doing this? And how do I set it up such that it persists after reboots?

Thanks.

Can we set easy-to-remember hostnames for EC2 instances?

I am trying to find somebody smarter than me to validate some syntax I wrote up.  The idea is to configure the filename of my RollingFileAppender to the name of the assembly in order to make it more re-usable for my projects.  

I&#39;ve seen [this previous SO article][1] but it wasn&#39;t exactly able to answer my question...

I&#39;ve had a dickens of a time trying to understand the inner components of Log4net and this is what I came up with (residing in the Global.asax file - Application_Start method):

    // Bind to the root hierarchy of log4net
    log4net.Repository.Hierarchy.Hierarchy root = 
      log4net.LogManager.GetRepository() 
        as log4net.Repository.Hierarchy.Hierarchy;
    
    if (root != null)
    {
      // Bind to the RollingFileAppender
      log4net.Appender.RollingFileAppender rfa = 
        (log4net.Appender.RollingFileAppender)root.Root.GetAppender(&quot;RollingLogFileAppender&quot;);
    
      if (rfa != null)
      {
        // Set the file name based on the assembly name
        string filePath = 
          string.Format(&quot;~/App_Data/{0}.log&quot;, GetType().Assembly.GetName().Name);
    
        // Assign the value to the appender
        rfa.File = Server.MapPath(filePath);
    
        // Apply changes to the appender
        rfa.ActivateOptions();
      }
    }

Can anyone tell me, &#39;this is hideous&#39;, or &#39;this should work fine&#39;?  Also, if I set the file dynamically can I still expect the log4net behavior to rotate the files based on the log4net.config file settings?

Much appreciated!

I received an `NSString` from the server. Now I want to split it into the substring which I need.

For example: 

substring1:read from the second character to 5th character

substring2:read 10 characters from the 6th character.

After a lot of trial and error, I&#39;m giving up and asking the question. I&#39;ve seen a lot of people with similar problems but can&#39;t get all the answers to work right.

I have a `UITableView` which is composed of custom cells. The cells are made of 5 text fields next to each other (sort of like a grid).

When I try to scroll and edit the cells at the bottom of the `UITableView`, I can&#39;t manage to get my cells properly positioned above the keyboard.

I have seen many answers talking about changing view sizes,etc... but none of them has worked nicely so far.

Could anybody clarify the &quot;right&quot; way to do this with a concrete code example?

What is the default height of a UITableViewCell? It looks like 44 pixels, but I&#39;d prefer to be sure.

What is the default height of UITableViewCell?

I&#39;ve been bashing my face into this one for literally days now and even though I feel constantly that I am right on the edge of revelation, I simply cannot achieve my goal.

I thought, ahead of time in the conceptual phases of my design, that it would be a trivial matter to grab a image from the iPhone&#39;s camera or library, scale it down to a specified height, using a function equivalent to the **Aspect Fill** option of UIImageView (entirely in code), and then **crop off** anything that did not fit within a passed CGRect.

Getting the original image from camera or library, was trivial. I am shocked at how difficult the other two steps have proved to be.

The attached image shows what I am trying to achieve. Would someone please be kind enough to hold my hand? Every code example I have found so far seems to smash the image, be upside down, look like crap, draw out of bounds, or otherwise just not work correctly.

I have an `ArrayList` that I want to output completely as a String. Essentially I want to output it in order using the `toString` of each element separated by tabs. Is there any fast way to do this? You could loop through it (or remove each element) and concatenate it to a String but I think this will be very slow.

I have some simple python code that searches files for a string e.g. `path=c:\path`, where the `c:\path` part may vary. The current code is:

    def find_path(i_file):
        lines = open(i_file).readlines()
        for line in lines:
            if line.startswith(&quot;Path=&quot;):
                return # what to do here in order to get line content after &quot;Path=&quot; ?

What is a simple way to get the text after `Path=`?


How to remove the left part of a string?

If I have a string like this:

    FOO[BAR]

I need a generic way to get the &quot;BAR&quot; string out of the string so that no matter what string is between the square brackets it would be able to get the string.

e.g.

    FOO[DOG] = DOG
    FOO[CAT] = CAT
