How do I split on all nonalphanumeric characters, EXCEPT the apostrophe?
re.split('\W+',text)
works, but will also split on apostrophes. How do I add an exception to this rule?
Thanks!

response.setHeader(keys[i].toString(),value);
in a servlet is throwing null pointer exception even though none of keys[i] or value are null why is it so?
df <- data.frame(var1=c('a', 'b', 'c'), var2=c('d', 'e', 'f'), freq=1:3)
What is the simplest way to expand the first two columns of the data.frame above, so that
each row appears the number of times specified in the column 'freq'?
In other words, go from this:
>df
var1 var2 freq
1 a d 1
2 b e 2
3 c f 3
To this:
>df.expanded
var1 var2
1 a d
2 b e
3 b e
4 c f
5 c f
6 c f

I'm testing some Java code that uses an android Bundle, and am getting a runtime exception whenever I create a Bundle in the unit test. The error I'm getting is java.lang.runtimeException at android.os.Bundle when I create the Bundle. It is running with the android SDK in the run configuration.
Has anyone run into this problem before?

We have following code:
try {
// some code throwing MyException
} catch (MyException ex) {
// [1]
// no (re)throw here
} catch (Exception ex) {
if (ex is MyException) {
// [2]
}
}
If we run the code without a debugger attached, everything runs fine. However, IF we debug the code, we don't get to point [1] but [2]. As far as I understand the language specification this should not be possible.
Even weirder, this code used run fine even while debugging. The strange behavior started only a few days ago.
I'm currently developing a replication system to keep data in-synch between an arbitrary number of servers.
Some of these servers exist in one cluster on one LAN. Others exist somewhere else in the world.
I'm wondering what are the pros/cons of different paths that we choose to flow replicated data on between servers?
In other words, what are the different strategies to load balance the replication process ?
Hi! I'm new to ejb. I'm trying to call the ejb from the servlet. But, I'm getting the NamingException. I'm directly running the servlet from the netbeans to check whether it is calling the ejb. But, it is not working. I'm getting the exception as home interface not bound. What is the solution for this?

Hi,
I want to reinstall Ubuntu keeping my data intact. I have 160 GB hardrive (sata or pata I don't know but it's slim and made in China) with a 40 GB ext3 partition, a 4GB swap memory and 3 other partition with a FAT32 file system. I have around 4GB space on my drive where Linux is installed.
I'd like to keep the data intact, especially the Downloads folder, desktop, and /var/www; And I no longer have access to any other machines or external storage devices.

"Type mismatch: cannot convert from org.w3c.dom.Document to javax.swing.text.Document"
how do i now typecast properly? any suggestions??
I am working on a PHP framework and am currently designing error handling. Based on what I have read on SO, I should only use exceptions for, well, exceptional situations. Therefore throwing an exception when an incorrect password is entered is wrong.
Should I avoid using exceptions when I want to trigger a server error? If so, should I write my own error handling class?
Hi,
The current situation encourages the design of the system to split object fields to seperate objects in order to reduce the chance of the JDOCanRetryException to be thrown.
If we could have the fields that were changed by the other client who changed the object in the exception content itself we could deside whether to re-retrieve the object or ignore...
Last summer I set up Change Data Capture for a client to track changes to their application database to apply those changes to their data warehouse. The client had some issues a short while back and felt they needed to increase the retention period from the default 3 days to 5 days. I ran this query to make that change: sp_cdc_change_job @job_type='cleanup', @retention=7200 The value 7200 represents the number of minutes in a period of 5 days. All was well, but they recently asked how they can verify...(read more)
