In Germany, there are 16 federal states, ten of which belonged to West Germany, six of which belonged to East Germany. In some respects, for example mortality rates of certain cancers, there are persistent differences between the ten former western states and the six former eastern ones. There are also differences among the states within the respective groups.
To show the differences among the states, it can make a certain amount of sense to plot data, for example age-standardized breast cancer mortality by year, from each state. A plot with 16 lines is not always a good choice, and I don't want to open up a discussion about that. Sometimes the powers that be say that's how it has to be.
**The problem**
Differentiating among 16 lines on a plot can be difficult. To do so, I usually use a combination of colors from the `RColorBrewer` package (the first ten colors of `Set3` plus the first six colors of that palette again, corresponding to the ten former west and six former east states) and line types (one line type for east, one for west). Using the `lattice` package, a plot of age-standardized breast cancer mortality rates from 1998-2010 by state could look like this:

**The question**
I would like to do a similar plot using `ggplot`, but I haven't figured out how to combine the colors and the line types in the legend. So far, I've gotten this far:
![unsatisfactory ggplot][2]
If it is possible to combine colors and line types in `ggplot` legends, how does one go about doing it?
Here's the code to create the data frame and the plots:

On my .jsp page, I have two autocompleter drop down menus. Each one returns a list of VOs from their specific table in the database, which is then used to call a search action that searches from another table. Menu A links to table A, and menu B links to table B, and they are used to search in table C. However, table B has a foreign key that links it to table A Table C has a foreign key that links it to table B.
I would like it to be that when the user picks an option from menu A, menu B is updated so it only includes options that contain the proper foreign key. The user then can pick something specific from menu B and have the action search table C only for rows containing the proper foreign key. If the user does not touch table B, then the action will search for all rows in table C containing all foreign keys from Table B that match the one chosen in table A.
I hope this is understandable and let me know if I need to clarify. I've been googling for some time and it might be a simple solution but I can't find anything. Thanks. | hibernate | spring-mvc | struts2 | foreign-keys | null | null | open | Update struts 2 autocompleter from another autocompleter

1.-The adapter of the ListView is a Simple Adapter, as you can see on the code, and I have found no examples of how to filter a Listview using such an adapter.
2.-I'm getting the info for the ListView through an Async Task, and setting up the ListView inside the *onPostExecute* method of the Async Task, and again, I have found no examples of filtering it when its in such a place.

The app.config produces ServerName.exe.config that in bin/Debug (previously I had it as embedded resource but it did not help either...
As you can see I increased all the numbers for buffers, messages, etc. to maximum and made sure that the time values are high enough... I am convinced that that the problem is that somehow either the server or the client do not know about these increased values, but cant figure out why...

The app.config produces ServerName.exe.config that in bin/Debug (previously I had it as embedded resource but it did not help either...
As you can see I increased all the numbers for buffers, messages, etc. to maximum and made sure that the time values are high enough... I am convinced that that the problem is that somehow either the server or the client do not know about these increased values, but cant figure out why...

SELECT COL1 FROM TABLE WHERE COL2 = ?
the value of COL2 is a number contained in a file, like a customer number, that is not a sequence. Looking and available classes in swingbench for demos I see that wherever swingbench read a file with (for example) productids then use a single product id calculating a random value between min and max value of the file. In my case this is not applicable.
How can I tackle this problem in java?
Thanks

Ignoring the connection to our external system for the moment, the simplest example would be:
Main.py:
import test-module.testing as thisTest
def doPrint(myvar):
print (myvar)
return
myTest=thisTest()
myTest.testprint()
test-module/__init__.py:
class testing():
def testPrint(self):
doPrint("Test message")
Clearly, the call to `doPrint()` in the class is always going to fail as it has no way of referencing the calling module.
Am I missing something really obvious here, or is this simply not the way to tackle the problem?
Many thanks! :)

I'm working with some Jython code where it makes sense for me to create an external module with a number of classes to encapsulate some of the date that we need model.

I've tried to design the API around resources, using hypermedia to link the resources together. As I've begun implementing things in Backbone, I'm starting to realize that accomplishing true hypermedia with Backbone may not be a good fit.
The main issue is backbone routers wanting to have their paths declared up-front. With a good Hypermedia API, resource URIs should not be hard-coded in the client, to allow for flexibility in adding new features and (*gasp*) changing resource locations.
I'm playing with the idea of decoupling client-level **Page Resources** from API-level **Object Resources**. Somebody scream if this is nuts. Basically, this would mean defining routes to resources within my backbone app (think a discrete page), which would then retrieve one or more API-level resources.
This leads to some interesting questions:
1. Is this even a good idea? Should I do my best to re-use the API-level resource URIs within my app such that the routes are 1-to-1.
- I realize that a *page* and an *api object* are just different representations of the same resource, but in most cases, a page is a composite of multiple resources. Or I'm just crazy :)
2. What happens with page-refreshes in the middle of a series of navigations. How do I know the location of the API-level resources if they aren't the same?
3. It seems to me that RESTful design emphasizes *discovery* over knowing things up front. Am I right in assuming this? Is this what code download is all about? Can someone point me to further reading if I'm going the right direction.
*Most* of the resources are read-only, and so only use the GET verb, but I do have a few scenarios that use POST/PUT (DELETE really isn't in the domain of this particular client, except for possibly aborting an order before it's placed fully).
*Let me just say that I am by no means a REST guru. I'm still in the process of learning, so feel free to tell me I'm off base completely. No feelings will be hurt. | rest | backbone.js | hypermedia | null | null | null | open | Working with a Hypermedia (REST) API in Backbone

The servers are duplicates of each other, running the exact same hardware and software.
Each server spec is:
7 GB of memory
20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each)
1690 GB of instance storage
64-bit platform

A couple of weeks ago we have run a yum upgrade on one of the servers. Starting on this upgrade the upgraded server started showing a high load average.
Needless to say, we did not update the other servers and we can not do so until we understand the reason for this behavior.
The strange thing is that when we compare the servers using top or iostat, we can not find the reason for the high load.
Note that we have moved traffic from the "problematic" server to the others, which have made the "problematic" server less crowded in terms of requests, and still his load is higher.
Do you have any idea what could it be, or where else can we check?
Many thanks for the help!

I would like to allow the user to perform a query based on tags (using only a AND operator for more then 1 tag).
For example lets say a user searches for a rainy day.
Select * from Photo where tag='clouds' AND tag='rainy'
How does the zig-zag merge work? I know that two scans are performed, and based on if the keys from both searches point to the same Photo then it's returned. Does this happen in parallel however? Ex: While Search 1 finds a photo that contains tag 'clouds' , Search 2 is finding the first photo that contains tag "rainy". When both searches are done, it becomes synchronous. Search 1 then continues it's scan until it hits the same key as S2. Then while the keys for each search are the same, the photo is returned, and the "cursor" is moved along 1 step for each search?
Secondly, does defining multiple indexes speed up these sort of queries? Ex, if I wanted to allow up to 4 tags then I would need to define the indexes such as:
Index(Photo)
Index(Photo, tag)
Index(Photo, tag,tag)
Index(Photo, tag,tag,tag)
Index(Photo, tag,tag,tag,tag)
Then, performing the same query above will be quicker?
Also, using our original query, lets say we have Millions of photos tagged as cloudy, but only two are tagged as rainy. Does this mean zig-zag will perform relatively slow? Since one of the searches will try to find a matching key exist? Even worse, if we have one million photos tagged "rainy" and one million are tagged "cloudly" yet no single photo have both tags in them. Will defining the above index's fix this issue?
Lastly, lets say a photo has 100 tags. Does that mean all the index's above have to include EVERY combination of the 100 tags?
I know there are got-yas (such as a entity can only be indexed 5000 times, and a single multi-valued property can only be indexed a 1000 times).

The child views are spread out within the parent with no overlap (and with some space in between). As a user moves her finger around the screen (without lifting it), I'd like to track touches as they enter and exit each of the child views.
**Example**: If the user begins touching somewhere on the screen outside of the child views, then swipes her finger over child 1, off of child 1, over child 2, and then lets go, I would expect these events to be triggered:
1. Touch began
2. Touch entered child 1
3. Touch exited child 1
4. Touch entered child 2
5. Touch ended
It seems as if touchesBegan:withEvent: and touchesEnded:withEvent: methods would be helpful in this case, but when I define them on the child view controllers, they don't do exactly what I want -- if the user begins touching outside the child view, then swipes over the child view, no touch events are triggered on the child itself.
**Current Solution**: I'm currently using a solution that feels really hacky to accomplish this. I'm observing touchesBegan:withEvent:, touchesEnded:withEvent:, and touchesMoved:withEvent: on the parent, grabbing the coordinates of each event, and determining if they lie within the bounds of a child. If they do, I trigger the appropriate events as described above.
This method mostly works, but feels very inefficient. It feels like the framework should handle this work for me. My state management code also sometimes misses an "enter" or "exit" trigger and I suspect it's because touch events were either dropped or came to me in an unexpected order.

You can imagine how happy and proud I was when I saw this. I find it weird since this is the only place where it happens (so far...). I registered the shell extension under the "directory" registry key so it shows up only when a folder is right clicked.
I've found some good article on shell extensions and I made it so far with those, but I'm nowhere near my comfy zone in this winapi stuff. I did a lot of fiddling with the ids, but I can't figure out what the problem is.
Here is my querycontextmenu implementation and I hope I made a dumb mistake in there that a c++ guru can spot right away. Any help will be appreciated.

I developed a very basic shell extension for a little application I'm working on. I've been using it for a while now without any problem, but I just noticed that in Windows xp, in start menu -> all programs, if I right click on a folder there and choose "open" or "explore", my little application shows up instead of an explorer window. You can imagine how happy and proud I was when I saw this. I find it weird since this is the only place where it happens (so far...). I registered the shell extension under the "directory" registry key so it shows up only when a folder is right clicked.

For all the other pages (html/php) I am using URL rewrite rules to remove the extension, however whenever I try to do it for the asp-net page I keep on getting a 403:Forbidden Error.
I have made sure that the sermons.aspx has full read/write control etc.
Could someone please point me in the right direction?
I am no expert and this, but I'm willing to learn and I appreciate any help that you can provide me.
Thank you. | 0 |

First, I am using the following code to download the image from the web:

try {
imageUrl = new URL("http://www.hmdb.ca/labm/metabolites/"
+ HMDB + "/ms/spectraH/" + HMDB + "H.png");
} catch (MalformedURLException e) {
e.printStackTrace();
}
Image image = Toolkit.getDefaultToolkit().createImage(imageUrl);
return image;
}
Then I made a new method that resizes the image:
public static BufferedImage resizeImage() {
final BufferedImage bufferedImage = new BufferedImage(300, 500,BufferedImage.TYPE_INT_RGB);
final Graphics2D graphics2D = bufferedImage.createGraphics();
graphics2D.setComposite(AlphaComposite.Src);
graphics2D.drawImage(MSImageHigh(), 0, 0, 200, 200, null);
graphics2D.dispose();
return bufferedImage;
}
This should produce s a new image that is resized to 200x200 px. What it in fact does is give me a black screen that is 200x200px in size. Btw, I also tried using TYPE_INT_ARGB instead of TYPE_INT_RGB, and this produces a totally transparent image, so that is not working either. | java | bufferedimage | null | null | null | null | open | Getting a black screen after trying to resize an image

At each sample (at about 30 Hz) each accelerometer gives me a X Y and Z value.
I have used the jahmm java library for classification of a datastream consisting of one accelerometer. This works fine. But now i am confused about how to extend my code so that it can be fed with more than one accelerometer.
a single datastream looks like this:
[-4.976763 7.096352 1.3488603]; [-4.8699903 7.417777 1.3515397];...
The library allows to define the dimensionality of the feature vector. In the above stream the dimensionality is 3. I thought of raising the dimensionality to 3 x 8 = 24, and then simply concatenate all accelerometers into a single 24D feature vector.
is this the way to go or will this deteriorate my results?

Now if new events are being raised, should I not process them until I get the problem event processed? Would this be manual intervention? Also other events will all get queued behind the problem event and nothing gets updated in the reporting database.

I am using an iterator over the set, and I want to group 2 sets in one, removing one of them. However, I am having a problem with the [`Iterator.remove()`][1] method.
What this program prints is:

+ Checking [1, 3] in [[1, 3], [2], [1, 5], [6, 8], [1, 7]]
- Removed [1, 3] -> [[2], [1, 3, 5], [6, 8], [1, 7]]

The first time, removing `[1, 3]` works as expected, but the rest of the times, it does not remove the item. I think it's because I use `addAll()`, but why is that? Because I don't make changes in `groups`; I only change an element inside it(`other`) - and the reference is the same, right?

I want to saturate the bus but without using too many CPU cycles, so that any performance degradation will be caused only by bus contention.

Senthil | java | web-services | java-ee | null | null | null | open | Cannot create proxy in jboss 5.0.1
===
I am using jboss 5.0.1 server and I have written a web service client using jax-rpc,I get the following exception when I run it. Since Jboss web service is not accepting user defined java beans to be passed in / out of jax-rpc so I have converted all the java beans object into String and String arrays and primitive data types. So I would be invoke the web service from my client.But when I try to call my web service it throws me the following exception. Please help me.

When my app first starts up, I read a directory from the file system and load contents of each file into the ConcurrentHashMap using the filename as the key. Some files may be empty, in which case I set the value to "empty".
Once all files have been loaded, a pool of worker threads will wait for external requests. When a request comes in, I call the getData() function where I check if the ConcurrentHashMap contains the key. If the key exists I get the value and check if the value is "empty". If value.contains("empty"), I return "file not found". Otherwise, the contents of the file is returned. When the key does not exist, I try to load the file from the file system.
private String getData(String name) {
String reply = null;
if (map.containsKey(name)) {
reply = map.get(name);
}
else {
reply = getDataFromFileSystem(name);
}
if (reply != null && !reply.contains("empty")) {
return reply;
}
return "file not found";
}
On occasion, the ConcurrentHashMap will return the contents of a non-empty file (i.e. value.contains("empty") == false), however the line:
if (reply != null && !reply.contains("empty"))
returns FALSE. I broke down the IF statement into two parts: if (reply != null) and if (!reply.contains("empty")). The first part of the IF statement returns TRUE. The second part returns FALSE. So I decided to print out the variable "reply" in order to determine if the contents of the string does in fact contain "empty". This was NOT the case i.e. the contents did not contain the string "empty". Furthermore, I added the line
int indexOf = reply.indexOf("empty");
Since the variable reply did not contain the string "empty" when I printed it out, I was expecting indexOf to return -1. But the function returned the a value approx the length of the string i.e. if reply.length == 15100, then reply.indexOf("empty") was returning 15099.
I experience this issue on a weekly basis, approx 2-3 times a week. This process is restarted on a daily basis therefore the ConcurrentHashMap is re-generated regularly.
Has anyone seen such behavior when using Java's ConcurrentHashMap?

Some of these files are huge, up to gigabytes of data. Needless to say, these files need to be parsed as a stream because loading them into memory is much too inefficient and often leads to OutOfMemory troubles.
I have used the libraries miniDOM, ElementTree, cElementTree and I am currently using lxml.
Right now I have a working, pretty memory-efficient script, using `lxml.etree.iterparse`. The problem is that some of the XML files I need to parse contain encoding errors (they advertise as UTF-8, but contain differently encoded characters). When using `lxml.etree.parse` this can be fixed by using the `recover=True` option of a custom parser, but `iterparse` does not accept a custom parser. (see also: [this question](http://stackoverflow.com/questions/2352840/parsing-broken-xml-with-lxml-etree-iterparse))
My current code looks like this:
from lxml import etree
events = ("start", "end")
context = etree.iterparse(xmlfile, events=events)
event, root_element = context.next() # <items>
for action, element in context:
if action == 'end' and element.tag == 'item':
# <parse>
root_element.clear()
Error when `iterparse` encounters a bad character (in this case, it's a `^Y`):
lxml.etree.XMLSyntaxError: Input is not proper UTF-8, indicate encoding !
Bytes: 0x19 0x73 0x20 0x65, line 949490, column 25
I don't even wish to decode this data, I can just drop it. However I don't know any way to skip the element - I tried `context.next` and `continue` in try/except statements.
