We have a background process that packages up data in a .pdf, and we don't want to bog down the page loads waiting for this to occur, so we want to put all this processing in a shell.
I've figured out how to pass values to a shell with $this->args
I know you can use App::import('Shell','TestShell')... but after that I am lost.
How do I call the main() function of the shell within a controller? | shell | cakephp | controller | null | null | null | open | CakePHP 1.3 - Calling Shells from a Controller?

I have a complex model object tree in Java that needs to be translated back and forth into an XML document. The object structure of the XML document's schema is extremely different from the model's object tree. The two are interchangeable, but the translation requires lots of context-driven logic where parent/child-like relationships are used.
**Some Background**
I'm working with model objects that are well established in a older system and the XML document's schema is fairly new. Since lots of our code depends on the structure of the model objects, we don't want to restructure them. Here is a simplified example of the type of structural differences I'm dealing with:
> *Example data model tree*
> Item
> * Description
> * cost
> * ...
> Person
> * First Name
> * Last Name
> * Address
> * ...
> Address
> * Street
> * City
> * ...
> Sale_Transaction (*this is the thing being translated)
> * Buyer (Person)
> * Seller (Person)
> * Sold Items[] (List<Item>)
> * Exchanged Items[] (List<Item>)
> * Location of Transaction (Address)
> *Example XML Document Structure*
> Exchange
> * Type
> * Parties
> * contact_ref
> * id
> * contact_id
> * Exchange Details
> * type
> * total_amount_exchanged
> * Items
> * Item
> * type
> * owning_party_contact_ref_id
> * exchange_use_type
>* Contacts
> * Contact
> * id
> * type
> Exchange Type: [ CASH SALE | BARTER | COMBINATION CASH AND BARTER ]
> Contact Type: [ PERSON | ADDRESS ]
> Exchange Details Type: [ CASH EXCHANGE | BARTER EXCHANGE ]
Mapping between Sale_Transaction and Exchange is possible, just not 1-1. In the example, the "buyer" in the model would be mapped to both a contact and a contact reference element in the XML document. Also, the value of the "owning_party_contact_ref_id" attribute of an "Item" element would be determined by looking at several different values in the Sale_Transaction object tree.
If an object tree I'm working with needs some translation in order to be used in an XML document, my go-to tool is an XmlAdapter. In this case though, I don't see using JAXB XML adapters as a viable solution. As far as I know, XmlAdapters work with individual objects and don't have a way to get at the context of the entire tree being marshalled/unmarshalled.
**The Question**
I'm sure this type of problem is fairly common, so how do you handle it? Is there a way of handling this problem with standard tools?
**What I've come up with**
In case it's interesting, here are the possible approaches that I've come up with:
*#1*
Separate the object tree translation problem from the XML generation problem. I have a home-grown tool that assists with generating object trees based on some context object. I could create the JAXB classes from the XML schema, then rely on this tool to generate the objects of those classes based on the context of our model object. This would work well to generate an XML document from the model object tree, but not the other way around. It also means relying on non-standard tools, which I'd like to avoid if possible.
*#2*
Go XmlAdapter crazy and modify the model classes to be able to retain translation state information (e.g. This object in the model tree was used to create this element in the XML document). This would keep the problem very close to the standard usage model for JAXB, but I think it would be a nightmare to develop, test and maintain.
*#3*
Separate the object tree problem like I would in #1, but use JDOM instead of JAXB. This would remove all of the JAXB required classes and mappings, but require another custom tool be built to manage the model object to DOM tree mappings.
I'm not super excited about any of the three solutions, but I'm most partial to #1. | java | xml | jaxb | mapping | null | null | open | Generating an XML document from Java objects where the structure is very different

After conversion to `namedtuple` it looks like:

But this doesn't work in the case of my refactored named tuple since it expects me to pass all the fields. I can of course replace the occurrences of `Node(val)` to `Node(val, None, None)` but it isn't to my liking.
So does there exist a good trick which can make my re-write successful without adding a lot of code complexity (metaprogramming) or should I just swallow the pill and go ahead with the "search and replace"? :)

when i select an option then select another before clicking submit, it alert one after the other, for eg if i click car then bike it alert bike then it flashes and the alert car. the aim is to only have it alert the final click or in other words the one that is the chosen option. so instead of alert both i want to alert bike since that was the final option | jquery | jquery-ui | null | null | null | null | open | jquery select return both options when click not the most recent

}
this code is for the Connect button. LinkedFrame is a new form for gathering required information including DB name, Username and Password.this form is created as you click the button and disappears as you fill in the fields all and press enter...
this is the LinkedFrame code:
private class DatabaseSelectionHandler implements ActionListener{
public void actionPerformed(ActionEvent evt){
database=jTextField1.getText();
username=jTextField2.getText();
pass=new String(jPasswordField1.getPassword());
if(database.isEmpty() || username.isEmpty() || pass.isEmpty())

else
{ setVisible(false);
if (service.equalsIgnoreCase("sqlserver"))
Connector.MSSQLConnection(service);
else
Connector.ORACLEConnection(service);
}
}
}
now I have some questions:
1- I have used the Connector method in the linkedFrame event handler with static attributes for sharing between my classes...is there any other way to share these attributes?!!
2-I want to resize my main frame(not linkedframe) as soon as connection is made in order to make queries. how can it be coded?and where?

On a particular step of the wizard I am collecting information, the user is required to click a link button which performs a postback and populates a datagrid on the same step of the Wizard.
The data is loaded into a dataset and the databind is working fine and information is displayed on the page. Along with this the dataset is loaded into a session object for use later in the wizard.
When the user is finished on this particular step the next button (on the wizard) is clicked and a check is performed to make sure that ample information is provided. This is done by retrieving the dataset from the session object and the relevant table is interrogated.
In Google Chrome, IE and Opera this works fine and the dataset is retrieved and the data exists. However in Safari 5.1.5 and Firefox 14 the dataset is empty. Exactly the same code is run for all browsers.
I have stepped through the code in using both Google and Safari and when in Safari the datatable of the dataset is empty even though it was used to populate the datagrid.
I though perhaps that the dataset was being corrupted before being loaded into the session object, but I have tested this by retrieving the dataset from the session immediately after is was assigned to the session variable and then serializing the dataset to XML. The XML file shows that the information was loaded into the datatable and into the session.
Has anyone seen behaviour like this before or have any suggestions as to where to go from here.
Thanks in advance

So I will tell you what I'm doing, first I need to find the tuples that have a father and two sons, if the two sons have a sequence they go to the deque run otherwise they go to wait, then it align the run, put it in done and check the wait to see where is it in wait as a son, check if the other son has a sequence, if it has it aligns them and so on until there are no more waiting, but I don't know where could it be the race cond. because i have a mutex blocking any read or write for the queues, I hope is clear to check it, thanks. | c++ | multithreading | boost | race-condition | null | 07/31/2012 08:12:55 | too localized | I have a race condition in my code

And here is the code for ExampleResponseAssembler.java ("response_assembler" bean). It is the last element in the route. And it's responsibility to get unmarshalled response object from some external service (from AHC component, actually) and assemble the proper SOAP response for overall route.
public class ExampleResponseAssembler implements Processor {

public void process(final Exchange exchange) throws Exception {
final Object responseMessage = exchange.getIn().getBody();
final GetRegionsResponse regionsResponse = new GetRegionsResponse();
final MessageDataType messageData = new MessageDataType();

final HeaderType header = exchange.getProperty("exampleHeader", HeaderType.class);
exchange.getOut().setHeader("CamelSpringWebServiceSoapHeader", header);
}
}
When I set the Body that way it is parsed correctly. I can see it in SaopUI. But header is not there. That was a naive approach to set the SOAP header I guess.
And I can't find any relevant info about this.
Although I was able to find some JIRA tickets regarding this problem - [link][1], it is still unclear how to handle with setting some custom SOAP headers. And ticket is marked as "unresolved"
Maybe I need some override voodoo magick here (override MessageFactory, MessageSender or something else). Seems like a minor issue, but...

I have configured Camel SOAP proxy service using Spring DSL. Everything was working nice untill I found that I need to set a custom header inside <soapenv:Header/> for SOAP response message.
I am using spring-ws component and latest Camel 2.10.0.

<bean id="response_assembler" class="ru.fabit.ExampleResponseAssembler"/>
<camel:camelContext id="get_regions">

because it is implicit from the Diff List...
- should i attach to the List `OnCollectionChanged` Event and then check if it changes `IsSame` ?
- should i use a backing field anyway and handle the List `OnCollectionChanged` ?

I have test it and there is no `gl_error` happened. Any body can help? The blend function works ok between the background color which `glColor` set and the first `glDrawPixels`. However, it don't work between the first and the second `glDrawPixels`, why? | 0 |

11,571,980 | 07/20/2012 02:20:36 | 111,910 | 05/25/2009 02:33:50 | 1,446 | 23 | R: `unlist` using a lot of time when summing a subset of a matrix | I have a program which pulls data out of a MySQL database, decodes a pair of
binary columns, and then sums together a subset of of the rows within the pair
of binary columns. Running the program on a sample data set takes 12-14 seconds,
with 9-10 of those taken up by `unlist`. I'm wondering if there is any way to
speed things up.
## Structure of the table
The rows I'm getting from the database look like:
| array_length | mz_array | intensity_array |
|--------------+-----------------+-----------------|
| 98 | 00c077e66340... | 002091c37240... |
| 74 | c04a7c7340... | db87734000... |
where `array_length` is the number of little-endian doubles in the two arrays
(they are guaranteed to be the same length). So the first row has 98 doubles in
each of `mz_array` and `intensity_array`. `array_length` has a mean of 825 and a
median of 620 with 13,000 rows.
## Decoding the binary arrays
Each row gets decoded by being passed to the following function. Once the binary
arrays have been decoded, `array_length` is no longer needed.
DecodeSpectrum <- function(array_length, mz_array, intensity_array) {
sapply(list(mz_array=mz_array, intensity_array=intensity_array),
readBin,
what="double",
endian="little",
n=array_length)
}
## Summing the arrays
The next step is to sum the values in `intensity_array`, but only if their
corresponding entry in `mz_array` is within a certain window. The arrays are
ordered by `mz_array`, ascending. I am using the following function to sum up
the `intensity_array` values:
SumInWindow <- function(spectrum, lower, upper) {
sum(spectrum[spectrum[,1] > lower & spectrum[,1] < upper, 2])
}
Where `spectrum` is the output from `DecodeSpectrum`, a `matrix`.
## Operating over list of rows
Each row is handled by:
ProcessSegment <- function(spectra, window_bounds) {
lower <- window_bounds[1]
upper <- window_bounds[2]
## Decode a single spectrum and sum the intensities within the window.
SumDecode <- function (...) {
SumInWindow(DecodeSpectrum(...), lower, upper)
}
do.call("mapply", c(SumDecode, spectra))
}
And finally, the rows are fetched and handed off to `ProcessSegment` with this
function:
ProcessAllSegments <- function(conn, window_bounds) {
nextSeg <- function() odbcFetchRows(conn, max=batchSize, buffsize=batchSize)
while ((res <- nextSeg())$stat == 1 && res$data[[1]] > 0) {
print(ProcessSegment(res$data, window_bounds))
}
}
I'm doing the fetches in segments so that R doesn't have to load the entire data
set into memory at once (it was causing out of memory errors). I'm using the
`RODBC` driver because the `RMySQL` driver isn't able to return unsullied binary
values (as far as I could tell).
## Performance
For a sample data set of about 140MiB, the whole process takes around 14 seconds
to complete, which is not that bad for 13,000 rows. Still, I think there's room
for improvement, especially when looking at the `Rprof` output:
$by.self
self.time self.pct total.time total.pct
"unlist" 10.26 69.99 10.30 70.26
"SumInWindow" 1.06 7.23 13.92 94.95

I'm surprised to see `unlist` taking up so much time; this says to me that there
might be some redundant copying or rearranging going on. I'm new at R, so it's
entirely possible that this is normal, but I'd like to know if there's anything
glaringly wrong.
| r | matrix | data.frame | null | null | null | open | R: `unlist` using a lot of time when summing a subset of a matrix
===
I have a program which pulls data out of a MySQL database, decodes a pair of
binary columns, and then sums together a subset of of the rows within the pair
of binary columns. Running the program on a sample data set takes 12-14 seconds,
with 9-10 of those taken up by `unlist`. I'm wondering if there is any way to
speed things up.
## Structure of the table
The rows I'm getting from the database look like:
| array_length | mz_array | intensity_array |
|--------------+-----------------+-----------------|
| 98 | 00c077e66340... | 002091c37240... |
| 74 | c04a7c7340... | db87734000... |
where `array_length` is the number of little-endian doubles in the two arrays
(they are guaranteed to be the same length). So the first row has 98 doubles in
each of `mz_array` and `intensity_array`. `array_length` has a mean of 825 and a
median of 620 with 13,000 rows.
## Decoding the binary arrays
Each row gets decoded by being passed to the following function. Once the binary
arrays have been decoded, `array_length` is no longer needed.
DecodeSpectrum <- function(array_length, mz_array, intensity_array) {
sapply(list(mz_array=mz_array, intensity_array=intensity_array),
readBin,
what="double",
endian="little",
n=array_length)
}
## Summing the arrays
The next step is to sum the values in `intensity_array`, but only if their
corresponding entry in `mz_array` is within a certain window. The arrays are
ordered by `mz_array`, ascending. I am using the following function to sum up
the `intensity_array` values:
SumInWindow <- function(spectrum, lower, upper) {
sum(spectrum[spectrum[,1] > lower & spectrum[,1] < upper, 2])
}
Where `spectrum` is the output from `DecodeSpectrum`, a `matrix`.
## Operating over list of rows
Each row is handled by:
ProcessSegment <- function(spectra, window_bounds) {
lower <- window_bounds[1]
upper <- window_bounds[2]
## Decode a single spectrum and sum the intensities within the window.
SumDecode <- function (...) {
SumInWindow(DecodeSpectrum(...), lower, upper)
}
do.call("mapply", c(SumDecode, spectra))
}
And finally, the rows are fetched and handed off to `ProcessSegment` with this
function:
ProcessAllSegments <- function(conn, window_bounds) {
nextSeg <- function() odbcFetchRows(conn, max=batchSize, buffsize=batchSize)
while ((res <- nextSeg())$stat == 1 && res$data[[1]] > 0) {
print(ProcessSegment(res$data, window_bounds))
}
}
I'm doing the fetches in segments so that R doesn't have to load the entire data
set into memory at once (it was causing out of memory errors). I'm using the
`RODBC` driver because the `RMySQL` driver isn't able to return unsullied binary
values (as far as I could tell).
## Performance
For a sample data set of about 140MiB, the whole process takes around 14 seconds
to complete, which is not that bad for 13,000 rows. Still, I think there's room
for improvement, especially when looking at the `Rprof` output:

I thought about putting this on severfault, but it's more of a coding question.
I've developed an API that uses LAMP to serve and receive data from multiple applications (android, iphone, etc)
It's main tasks are doing mysql queries (some simple, some rather complex) and serving the responses as raw JSON data,
storing vector and image file mysql blobs (base64 encoded, also get served through JSON),
receiving base64 encoded images as POST data and doing image processing using GD library and imagemagick
In development/alpha I don't have any problems with speed or efficiency, however we are ready to get a dedicated server going to serve very high volume traffic (hundreds of thousands of people logging in daily),
So, my question: How does PHP + Apache stack up to other configurations/coding language in terms of speed and ability to handle many connections, given my API's tasks?
I know Ruby on Rails pretty well, and JavaScript pretty fluently, so I have been doing my homework on RoR3 and node.js
But I want to know, what are your experiences as seasoned developers?
I honestly trust SO more than most of the blogs I've been reading.
Thanks for all of your input

* Expired
* Tamper Resistant
* Single Use
* Resistant to replay attacks
The format of the reset code I have come up with is:
B64(B64(iv)||B64(E(uid||timestamp)))
Where B64 is base64 encoding and E is for symmetric encryption. The iv is the initialization vector used for encryption (randomly generated), and is in the clear. The || indicates concatenation and I actually use the string "||" as the separator. The uid is an opaque identifier of the user so I can look them up in the database.
The timestamp allows for a code to be expired.
I am using AES 256 in Galois Counter Mode which should provide protection from modified ciphertext attacks.
The encryption key is stored on the server, and used to perform the encryption.
The iv has a dual use. When the reset code is generated the iv is stored with the user in the database. This is used to enforce single-use of a reset code (it gets cleared when a reset code is processed) as well as prevent use of reset codes generated previously. If the iv in the database does not match the iv used to decrypt the reset code, the request is refused. This may also help with security in the event that the encryption key on the server is somehow compromised, as the attacker has to inject the iv into the database as well to make it work. Of course if the attacker is on the host we are pretty much toast...
Are there any weaknesses in this design I am not seeing, or does it needs additional improvement? I look forward to your comments.

The code in question is `execute javascript "document.getElementById('Email').value = '" & Username & "'"`. Whenever I try to execute the JavaScript using string concatenation, I get the following error: "Can’t make {text returned:"hello", button returned:"OK"} into type Unicode text."
I've also tried to use the following instead of altering the field's value <br />
`execute javascript "document.getElementById('Email').click()"` along with a `keystroke` command. However, that didn't work either. Am I doing something wrong, or is it just AppleScript?
It is worth noting that the following code works <br /> `execute javascript "document.getElementById('Email').value = '" & "Hello" & "'"`.

I don't want to have to make them go through this step, though.
How are shortcuts placed by an installer different from "normal" shortcuts?

We are new in taking part in App Development, so we enroll for the 99$ in the iOS Dev Center.
Up to here all is clear and we know how to use the iOS Dev Center and XCode to develop Apps.
But now one client ask us if we can't develop some Apps for him and use his Enterprise license.
For that he gave us some files. So we got a distribution.cer, distribution.p12 (Password protected), distribution.pem and key.key file.
Here starts now my question what and how i can do with that files, that i can develop a small Demo App with his Enterprise license.
I will be really appreciation, if some one can help me and explain if with that files it is possible to develop a App or if it is impossible because of.

I want to create a page where users can invite friends to sign up. The page would contain a number of fields where a user can enter email addresses. I would like these stored in an array. Basically each field on the page would be an element in the array. My hope is to loop through the array elements, verify each email address entered, update a temp email field on my table then launch an ActionMailer to send the invite email.
I would like this array initialized each time the user goes to the invite page. From what I have read in the book **Programming Ruby 1.9** I should be able to declare an array like this somewhere.
friend_email = Array.new
I need the variable available long enough to access it in my controller when I verify the data entered in my view. From my limited understanding of variables they generally are not available outside of where they are declared aka initialized. This makes it interesting when trying to send entered information to a mailer. I have used temp fields on my model to simplify things.
If there is a better way to do this I would appreciate the information. I will also continue doing research. I have seen only the one I list below where an array is populated by an existing table then displayed in a view. I want to populate the array from the view.

I used Wireshark to capture this on my Linux box. The robotic device is 192.168.2.5, my Linux box is 192.168.2.3. Wireshark calls the UDP port 5020 "zenginkyo-1". The packets are rather small: 8 and 14 bytes length.
This way it looks most of the time, and the communication works without any trouble. However, sometimes it happens that the robotic device signals an error. This error is rather hard to trace.

The robotic device sends its request, and I send the answer (No. 608 and 609).
After that, the device sends a bunch of empty packets, starting with No. 610. It seems to be signaling a change in the TCP window size: Win=8179. Please notice that it usually claims Win=8192. After this, it increments the window size by 1 or 2 until it reaches 8192 again. Then it waits until it sends its next request, where the same pattern accurs again and again.
I do not get my mysterious error every time I watch this pattern, but everythime I see the error, I see this pattern too. This might be evidence that the two are related.
Please notice that packets 610 to 617 share the same TCP sequence number: Seq=2372. As of my understanding, this is not legal in TCP. Is this true?
I do not even know what these packages mean. I send only 14 bytes on every request, so the TCP window should be large enough in any case. Do you know how to make sense of this? Is there anything I can do on my Linux box to make these packages disappear, or is it bug in the robotic device? | c | unix | tcp | udp | null | null | open | Mysterious UDP packages altering TCP window size

You test the app, decide you want to make some changes. You stop the debugger. But, in actuality, the application is still running, you can still pull up pages, etc.
Then you update some library code, and launch again. Does it re-use an existing "app-pool"? Do objects with static initailizers get called again when enountered? Or are they only called again if they are from updated binaries (but unchanged library references are not reinitialized?) Are you starting from a blank slate?
The problem I am facing is that my server-side code is creating long-lived unmanaged objects (TCP connections, namely). I "stop debugging" my application, make a change, and try to launch it again. But I get an error, because the port is already bound, because the previous instance never fully "stopped" and let go of it. Even if I right-click the IIS Express icon in the system tray, and tell it to "stop all", it doesn't seem to help. Sometimes, by trying to relaunch I'll get an error that IIS Express crashed. Sometimes, the only thing I can do is closed down VS2010, open my solution again, and then launch. Obviously, this is less than ideal.
Any ideas?

I'm currently trying to make the following customization, but unfortunately I am novice at PHP and couldn't make anything work in the way I'd like:
- I'd like to have it display only ###DATESTART### if it is an event lasting only a single day (all-day event), but if it is an event that lasts more than a day to display in the following format: ###DATESTART### - ###DATEEND###
Actual start times are not a factor for the front-end and will not be displayed to users.
One of the problem with the if statements I was making is that when an event is scheduled as an "all-day event" (let's say July 20), it outputs as July 20, 2012 @ 12:00am - July 21, 2012 @12:00, which is technically accurate, but confusing for users.
I was attempting to see if ###DATESTART### == ###DATEEND### but obviously for all-day events these would be different dates given the implementation of all-day events.
Any help here would be greatly appreciated!
