The () seems silly. is there a better way?
For example:
ExternalId.IfNotNullDo(()=>ExternalId=ExternalId.Trim());

For a lambda....
Whether there ever will be one or not is a different matter .
I know that the C# team feels your pain, and have tried to find an alternative .
Lambda expressions are optimised (in terms of syntax) for the single parameter case .
No, there isn't.

Quick one, but thought I'd ask.
Is there a better way of getting the column values from a model's column than something like this?
Item.count(:all, :group => 'status').reject! { |i, e| i.blank? }.collect { |i,e| i}

Status is blank? count is blank?
Item.find(:all, :select....
But then could you please specify more criteria you want? i.e .
Maybe not ..
Is it the same thing as the following code?
Item.count(:all, :group => "status", :conditions => "status != ''"}

What is the better way of getting the IP address in PHP:
getenv('REMOTE_ADDR');
or,
$_SERVER['REMOTE_ADDR'];
please tell me the difference, if any, between the two.

The common approach is to use....
Getenv() can be used to access any environment variables (PHP simply registers REMOTE_ADDR as an environment variable for the script), while with $_SERVER you obviously only access the contents of the $_SERVER superglobal .

This is related to my question asked here today on SO. Is there a better way to build a packet to send over serial rather than doing this:
unsigned char buff[255]; buff[0] = 0x02 buff[1] = 0x01 buff[2] = 0x03 WriteFile(.., buff,3, &dwBytesWrite,..);
Note...

There is a much better way, which is using structs to set.

Is there a better way to build a packet than concerns like this can help reuse.
This is left as an exercise for the reader.

Is there a better way of doing data validation in Perl than regex?
I have Perl code that does string and numeric data validation using complex regex, and this makes code difficult to read and follow, for everyone.

If you want to make sure variable values fit a certain pattern, there is no better way than to use.

In this answer to a question I asked. Kathy Van Stone says that adding an array like so
jList1.setListData(LinkedHashMap.keySet().toArray());
is a better way than to do it like this
jList1.setListData(new Vector<String>(LinkedHashMap.keySet()));...

I would prefer the first one, simply because there is no need to involve yet another collection (Vector)
Do you need the synchronization... .
Take a look at implementation of both setListData methods in JList class and you will see that it really doesn't matter .

Hi, This is probably trivial, but I can't think of a better way to do it. I have a COM object that returns a variant which becomes an object in C#. The only way I can get this into an int is
int test = int.Parse(string.Format("{0}", myobject))
Is there...

Int test; bool result = Int32.TryParse(value, out test); if (result) { Console.WriteLine("Sucess"); } else { if (value == null) value = ""; Console.WriteLine... .
Use Int32.TryParse as follows.
Watch out for exception, in both cases.
Maybe Convert.ToInt32.

I've always handled optional parameters in Javascript like this:
function myFunc(requiredArg, optionalArg){ optionalArg = optionalArg || 'defaultValue'; //do stuff }
Is there a better way to do it?

Your logic fails if optionalArg is passed, but evaluates as false - try this as an alternative
optionalArg = (typeof optionalArg == "undefined")?'defaultValue':optionalArg

Try this basically... .

I have a TreeSet, which will be full of integers. To make a long story short, I'm trying to loop starting after the last (greatest) value stored in the list. What I'm doing now to get the starting variable is:

Int start = 1 + last;

Also, if you know they're all going to be Integer objects, use the parameterized type:... .
In J2SE 5 or later it happens automatically, with the "autoboxing" feature .
