I get the following error:
Illegal Argument java/lang/IllegalArgumentException Current Displayable is an Alert
I'm not sure what is means and why this exception is fired.
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!
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?
Thanks!

<b>eWeek:</b> "Data Apple collects about users from its vaunted iPhone is so valuable that the company must build a special search engine just to keep Google from gleaning insight from that data, analysts say."
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

Experiments in Big Data Visualization on Maps
Brendan Kenny and Mano Marks continue their series on using the CanvasLayer library and HTML5 APIs to visualize large amounts of data on top of Google maps. This week they look at loading Shapefiles and KML directly in the browser and using WebGL to render their content over a map.

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 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.

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)
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.
