I have a set of daily returns of 4 assets, using a 10 day window I loop over the whole dataset (from `i` = 1 to 50) performing a number of calculations and building optimal portfolios. This involves using `portopt`.
[PortRisk(:,i), PortReturn(:,i), PortWts(:,:,i)] = portopt(ExpReturn(i,:), ExpCovariance(:,:,i), [], [], ConSet);
The inputs, `ExpReturn` and `ExpCovariance` are generated using `ewstats`
[ExpReturn(i,:), ExpCovariance(:,:,i)] = ewstats(RetSeries, 0.94)
Now, on the final 50th iteration (and only the 50th - all previous work fine), I get the following error:
??? Subscripted assignment dimension mismatch. Error in ==> Script at 10
[PortRisk(:,i), PortReturn(:,i), PortWts(:,:,i)] = portopt(ExpReturn(i,:), ExpCovariance(:,:,i), [], [], ConSet);
Note, I see no issue with `RetSeries` as `ExpReturn` and `ExpCovariance` generated by `ewstats` are size `<50x4>` and `<4x4x50>` respectively.
I have tried everything i can think of to hunt down the error, including checking `size()`, using breakpoints, preallocating the matrices etc etc. Oddly, if i remove the loop, set `i = 50`, it works. Furthermore, if instead of `ewstats` I simply use `mean()` and `cov()` - they work on the 50th iteration. If i replace one, `ExpReturn` for example, with a `mean(RetSeries)`, it works. Similarly, replacing `ExpCovariance` with `cov(RetSeries)` - works. But both `ExpReturn` and `ExpCovariance` together always fail.

I'm trying to figure out a way to change javascript code using javascript.
If thats not possible, then if you could suggest another way for me to accomplish what i'm trying to do it would be great.
Basically, a user selects option, which generates a customized javascript code for a clock (using php via ajax techniques). now this code is run using the eval statement, and the clock is displayed in a particular <div> element.
the eval() statement is run each time a response is received from server via AJAX.
Problem is, since it is a clock, I have used setInterval() to constantly update the time. Now if multiple ajax calls are run, multiple functions start to run in a loop.
i.e, after first server call we have this running:
setInterval(function and code for clock with format 1,1000);
AND
setInterval(function and code for clock with format 2,1000);
so basically, I want to somehow stop the first one from running before the second one starts..any ideas?

There are 5 main tables, **users** (which will contain user-related information to loggin into the system etc), **warehouses** (containing information about warehouse name, location and responsible person), **operations** (which will contain everything that goes in and out of a warehouse), **products** and **categories**.
One user will be responsible only for 1 warehouse (1-to-1 relation). Every product has a mother category. The same product, may be into different warehouses, which means that an operation for a product, can be done by different users (corresponding with the warehouse that the product is located).

There are 5 main tables, **users** (which will contain user-related information to loggin into the system etc), **warehouses** (containing information about warehouse name, location and responsible person), **operations** (which will contain everything that goes in and out of a warehouse), **products** and **categories**.
One user will be responsible only for 1 warehouse (1-to-1 relation). Every product has a mother category. The same product, may be into different warehouses, which means that an operation for a product, can be done by different users (corresponding with the warehouse that the product is located).
Here is a design I have made: http://i.stack.imgur.com/PBp1I.png
I would like to get any suggestions to improve the database design, what can I add, or what I have done wrong?
Thanks in advance.

I am following this example:
http://stackoverflow.com/questions/6681145/how-can-i-arrange-an-arbitrary-number-of-ggplots-using-grid-arrange
I wanted to collect the plots and lay them out on a 3x9 grid and each grid with suitable labels...
But it doesn't work. The pdf generated is still one-plot-per-page - so there are 27 pages generated.
I am trying to use "grid.arrange", however, the function "plotFunctionWrittenByOtherPeople" was written by other people, and it doesn't return a handle to the plot... and it's quite complicated.
How to arrange the plots nicely?
Could anybody please shed some lights on this?

$var = LONG_EXPRESSION(....);
if($var) {..};
if($var) {..};

This way it is a lot more logical and less error prone. easily maintained, readable, perhaps even optimized.
Is there an equivalent for this inside MYSQL ?
Thus, defining a parameter for every single row of execution ?

Integration of the NHibernate Facility
-
I have downloaded the [0.3.1.2001 artifacts][1] and using the resources below I have tried to plug in the facility and remove any manual wire up to NHibernate. However I do not want to decorate services and methods with the `Transactional` and `Transaction` attributes. The following is my current wire up.
<!-- language: lang-cs -->
container.Register(Component.For<INHibernateInstaller>().ImplementedBy<MyNHibernateInstaller>();
container.AddFacility<AutoTxFacility>();
container.AddFacility<NHibernateFacility>();
public class MyNHibernateInstaller : INHibernateInstaller
{
public Maybe<IInterceptor> Interceptor { get { return Maybe.None<IInterceptor>(); } }
public bool IsDefault { get { return true; } }
public string SessionFactoryKey { get { return "sf.default"; } }
public FluentConfiguration BuildFluent()
{
return Fluently
.Configure()
.Database(MsSqlConfiguration
.MsSql2005.ConnectionString("SomeConnectionString") )
.Mappings( m => m.FluentMappings
.AddFromAssemblyOf<TypeFromEntityAssembly>() );
}
public void Registered(ISessionFactory factory)
{
}
}
Whenever I call one of the service endpoints the service fails with the following exception:
> No transaction in context when trying to instantiate model
> 'NHibernate.ISession' for resolve type
> 'Juice.iCheque.eMoneySystem.Settlement.ISettlementService'. If you
> have verified that your call stack contains a method with the

The question is how do I use the `NHibernateFacility` with my current implementation and not use the `Transaction` attribute.

Integration of the NHibernate Facility
-
I have downloaded the [0.3.1.2001 artifacts][1] and using the resources below I have tried to plug in the facility and remove any manual wire up to NHibernate. However I do not want to decorate services and methods with the `Transactional` and `Transaction` attributes. The following is my current wire up.
<!-- language: lang-cs -->
container.Register(Component.For<INHibernateInstaller>().ImplementedBy<MyNHibernateInstaller>();
container.AddFacility<AutoTxFacility>();
container.AddFacility<NHibernateFacility>();
public class MyNHibernateInstaller : INHibernateInstaller
{
public Maybe<IInterceptor> Interceptor { get { return Maybe.None<IInterceptor>(); } }
public bool IsDefault { get { return true; } }
public string SessionFactoryKey { get { return "sf.default"; } }
public FluentConfiguration BuildFluent()
{
return Fluently
.Configure()
.Database(MsSqlConfiguration
.MsSql2005.ConnectionString("SomeConnectionString") )
.Mappings( m => m.FluentMappings
.AddFromAssemblyOf<TypeFromEntityAssembly>() );
}
public void Registered(ISessionFactory factory)
{
}
}
Whenever I call one of the service endpoints the service fails with the following exception:
> No transaction in context when trying to instantiate model
> 'NHibernate.ISession' for resolve type
> 'Juice.iCheque.eMoneySystem.Settlement.ISettlementService'. If you
> have verified that your call stack contains a method with the
> [Transaction] attribute, then also make sure that you have registered
> the AutoTx Facility.
The question is how do I use the `NHibernateFacility` with my current implementation and not use the `Transaction` attribute.

Because I want this program to look the same on whatever computer it runs on, and it needs to be fullscreen, I had the idea that I wanted to draw everything in a small 640,480 window, and then scale it to a fullscreen window every time I update the frame. This allows me to keep all the offsets the same for text, etc. It also turns out this is really slow.
Here's about what the important part of the code looks like:
window = pygame.display.set_mode((1920, 1080),pygame.FULLSCREEN)
screenPrescaled=pygame.Surface((640,480))
clock=pygame.time.Clock()
while iterations<400:
#Blit all the stuff to the prescaled surface here
screenPostscaled=pygame.transform.scale(screenPrescaled,(1920, 1080))
window.blit(screenPostscaled,(0,0))
pygame.display.flip()
iterations+=1
clock.tick(40)
This runs a WHOLE lot slower than 40fps. Everything on the screen is either text or lines, there are no images loaded.
I suspect I'm doing something stupid. I know I can update "dirty rectangles" only, but I wonder if I'm missing something more fundamental.
Thanks in advance!

Can't really explain what is going on. Sorry for a long listing, but it's really bugging me.
I have a GUI application which loads some files and uses a reader object which state can be set by using a `parse(int argc, char* argv[])` method. The arguments are set in a dialog by checking various boxes and entering values. Here is a struct I use to hold the data from the dialog:
struct PointFilter
{
PointFilter(): argc(0) {};
~PointFilter() {};
int argc;
std::vector<std::string> args;
};
This struct is a member of the dialog class and after pressing ok button its populated with appropriate values. The values are taken from text boxes on the dialog into a stringstream and then pushed back into a std::vector<std::string>:
class AdvancedLoadDialog
{
public:
AdvancedLoadDialog(const Glib::RefPtr<Gtk::Builder>&);
~AdvancedLoadDialog();
PointFilter get_point_filter()
{
return this->point_filter;
}
private:
PointFilter point_filter;
void on_ok_btn_clicked();
void AdvancedLoadDialog::on_ok_btn_clicked()
{
std::stringstream filter_stream;
// filter_stream << some_values_from_textboxes ...
std::vector<std::string> args;
std::string arg;
// we need a dummy first argument to emulate the command line
args.push_back("filter");
while (filter_stream >> arg)
{
args.push_back(arg);
}
point_filter.argc = args.size() > 1 ? args.size() : 0;
point_filter.args = args;
advanced_load_dialog->hide_all();
}
Everything works fine till this point and we have an `AdvancedLoadDialog` object with `point_filter` member which holds our arguments. Now in a separate window I take the point_filter object and pass it to a constructor of `LoadWorker` class, which loads the files and also has a `PointFilter` member.
load_worker = new LoadWorker(..., advanced_load_dialog->get_point_filter())
And then:
LoadWorker::LoadWorker(..., PointFilter pf) :
point_filter (pf)
All well and good. Now in the `LoadWorker::run()` function I take the arguments from the point_filter, convert them into std::vector<char*> and pass them them to the `parse(int argc, char* argv[]) function I need.
void LoadWorker::run()
{
std::cout << "LoadWorker::file_filter contents: \n"
<< "point_filter.argc: " << point_filter.argc << "\n"
<< "point_filter.args: " << std::endl;
for (int i = 0; i < point_filter.argc; ++i)
std::cout << point_filter.args[i] << std::endl;
// ...
if (point_filter.argc != 0)
{
std::cout << "Using filter: " << std::endl;
std::vector<char*> argv;
for (std::vector<std::string>::const_iterator it = point_filter.args.begin();
it != point_filter.args.end(); ++it)
{
argv.push_back(const_cast<char*>(it->c_str()));
}
argv.push_back(0);
for (int i = 0; i < point_filter.argc; ++i)
{
std::cout << argv[i] << std::endl;
}
if (!lasreadopener.parse(point_filter.argc, &argv[0]))
{
send_message("Error parsing filter parameters.");
sig_fail();
return;
}
}
}
Now this works... once. You can notice that the arguments are printed twice, first as elements of `LoadWorker::point_filter.args` vector and then as elements of the `vector<char*> argv`. If I set the filter and then press the load button it all works. If I then try to load another file, without changing `AdvancedLoadDialog::point_filter` at all, the arguments are disappearing. Here's an example output trying to load two files in a row.
> LoadWorker::file_filter contents: point_filter.argc: 6
> point_filter.args: filter
> -clip_z_above 12
> -keep_intensity 11 222 Using filter: filter
> -clip_z_above 12
> -keep_intensity 11 222 LoadWorker::file_filter contents: point_filter.argc: 6 point_filter.args: filter clip_z_above 2
> keep_intensity 1 22 Using filter: filter
>
> // 6 blank lines here
To make it even more odd, during the second run each string except the first one in `point_filter.args` is missing the first character and in the `argv` they are all empty.
Any clues whatsoever?

AdvancedLoadDialog(const Glib::RefPtr<Gtk::Builder>&);
~AdvancedLoadDialog();
PointFilter get_point_filter()
{
return this->point_filter;
}
private:
PointFilter point_filter;
void on_ok_btn_clicked();
void AdvancedLoadDialog::on_ok_btn_clicked()
{
std::stringstream filter_stream;
// filter_stream << some_values_from_textboxes ...
std::vector<std::string> args;
std::string arg;
// we need a dummy first argument to emulate the command line
args.push_back("filter");
while (filter_stream >> arg)
{
args.push_back(arg);
}
point_filter.argc = args.size() > 1 ? args.size() : 0;
point_filter.args = args;
advanced_load_dialog->hide_all();
}
Everything works fine till this point and we have an `AdvancedLoadDialog` object with `point_filter` member which holds our arguments. Now in a separate window I take the point_filter object and pass it to a constructor of `LoadWorker` class, which loads the files and also has a `PointFilter` member.
load_worker = new LoadWorker(..., advanced_load_dialog->get_point_filter())
And then:
LoadWorker::LoadWorker(..., PointFilter pf) :
point_filter (pf)
All well and good. Now in the `LoadWorker::run()` function I take the arguments from the point_filter, convert them into std::vector<char*> and pass them them to the `parse(int argc, char* argv[]) function I need.
void LoadWorker::run()
{
std::cout << "LoadWorker::file_filter contents: \n"
<< "point_filter.argc: " << point_filter.argc << "\n"
<< "point_filter.args: " << std::endl;
for (int i = 0; i < point_filter.argc; ++i)
std::cout << point_filter.args[i] << std::endl;
// ...
if (point_filter.argc != 0)
{
std::cout << "Using filter: " << std::endl;
std::vector<char*> argv;
for (std::vector<std::string>::const_iterator it = point_filter.args.begin();
it != point_filter.args.end(); ++it)
{
argv.push_back(const_cast<char*>(it->c_str()));
}
argv.push_back(0);
for (int i = 0; i < point_filter.argc; ++i)
{
std::cout << argv[i] << std::endl;
}
if (!lasreadopener.parse(point_filter.argc, &argv[0]))
{
send_message("Error parsing filter parameters.");
sig_fail();
return;
}
}
}
Now this works... once. You can notice that the arguments are printed twice, first as elements of `LoadWorker::point_filter.args` vector and then as elements of the `vector<char*> argv`. If I set the filter and then press the load button it all works. If I then try to load another file, without changing `AdvancedLoadDialog::point_filter` at all, the arguments are disappearing. Here's an example output trying to load two files in a row.
> LoadWorker::file_filter contents: point_filter.argc: 6
> point_filter.args: filter
> -clip_z_above 12
> -keep_intensity 11 222 Using filter: filter
> -clip_z_above 12
> -keep_intensity 11 222 LoadWorker::file_filter contents: point_filter.argc: 6 point_filter.args: filter clip_z_above 2
> keep_intensity 1 22 Using filter: filter
>
> // 6 blank lines here
To make it even more odd, during the second run each string except the first one in `point_filter.args` is missing the first character and in the `argv` they are all empty.
Any clues whatsoever?

For example message consumers that are servers (but not webservers and have no Servlets), or executable `.jar`s with Jetty embedded?
Building and deploying `.war`s is pretty straightforward: Maven has the war archetype, Jenkins has a heap of plugins for deploying `.war` files to various application servers, most of which accept the upload of new web applications at runtime. Tools like Elastic Beanstalk make this process even easier, tying in the management of server environments.
By contrast deploying executable `.jar`s seems like re-inventing the wheel. One needs to sort out the best way of shading the dependencies and creating an executable artefact with a plethora of Maven plugins, deposit this artefact somewhere, then find a way of installing it on target servers, and replacing/upgrading it if necessary (Debian packages would be one way of doing this).
This all seems very 'manual' to me, to the point that it seems advantageous to deploy applications as `.war`s to application servers, even if they're not a natural fit for such an environment, just so you get the benefit of tool support. | java | deployment | automation | build-automation | executable-jar | null | open | Deploying Java Server Applications That Aren't .wars

This seems problematic. If I want to make it secure, I use server side code for the voting, but this sounds like a terrible user experience.
With AJAX, the user experience is MUCH better, but you're vulnerable to hacking.
The main vulnerability I see, is assigning a vote to a user. I assume whatever the interface (let's assume Ajax to List) that these will be variables set in JavaScript.
It seems very easy to fire up any JS console in a browser and submit votes for a post/question.
Unless I want to validate every vote against a username on page_load (a lot of extra cycles) I feel like I'm limited to nesting a repeater inside an updatepanel, and handling the voting inside of that function, generating the SPUser identity server side.

This script runs without an error when I comment out "my @cols = split(/\s+/, $line)," but I can't figure out why a split would cause the signal.

Basically, I am implementing Karger's minimum cuts algorithm. It requires me to keep merging nodes in a graph and then compute the number of crossing edges at the end (an int value). This algorithm must be repeated n times, always from the starting graph. My problem is that I am unable to create a deep copy of my Graph object, and I can't find the mistake.
I have cropped the code to just show the problem and no more, but I am still unable to figure out what's wrong. Here the code is.
Class Node:
public class Node {
public Integer Data;
public Node() {
Data = 0;
}
public Node(Node rhs) {
Data = rhs.Data.intValue();
}
public Node(Integer rhs) {
Data = rhs.intValue();
}
public void setNode(Integer rhs) {
Data = rhs;
}
Class Graph:
public class Graph {
public ArrayList<ArrayList<Node>> AdjList;
public ArrayList<Node> NodeSet; // This contains all the nodes
public Graph() {
AdjList = new ArrayList<ArrayList<Node>>();
NodeSet = new ArrayList<Node>();
}
public Graph(Graph G) {
AdjList = new ArrayList<ArrayList<Node>>();
for (ArrayList<Node> L : G.AdjList) {
ArrayList<Node> Lcopy = new ArrayList<Node>();
for (Node N : L) {
Node copy = new Node(N);
Lcopy.add(copy);
}
AdjList.add(L);
}
}
public void addNewAdjList(ArrayList<Node> NodeAdjList) {
// Input is the adjacency list of a new node
// The first element in the NodeAdjList is the node itself, the rest is the adj nodes
AdjList.add(NodeAdjList);
}
public static void printAdjList(ArrayList<Node> Adjlist) {
Node start = Adjlist.get(0);
System.out.print(start.Data + " : ");
for (int j=1; j < Adjlist.size(); ++j) {
System.out.print(Adjlist.get(j).Data + ", ");
}
System.out.print("\n");
}
Main:
public class Main {
/**
* @param args
*/
public static void main(String[] args) {
Node Five = new Node(5);
Node Seven = new Node(7);
Node One = new Node(1);
Graph G = new Graph();
ArrayList<Node> L = new ArrayList<Node>();
L.add(Five);
L.add(Seven);
L.add(One);
G.addNewAdjList(L);
Graph R = new Graph(G);
R.AdjList.get(0).get(1).setNode(19); // Gets node #1 in the first adj list, i.e. 7
Graph.printAdjList(G.AdjList.get(0));
Graph.printAdjList(R.AdjList.get(0));
}
}
Output:
> 5 : 19, 1,
> 5 : 19, 1,
This kind of puzzles me to be honest. I understand that Java is pass by value only, but objects are always represented by their reference. As far as I understand, my copy constructor for G should always make a deep copy: I am moving through every adjacency list and then I am making a deep copy of the Node. I don't understand why invoking .setNode() on the copied object modifies also the original object (that has a different reference).
Previous answers like [1][1] seem to go the same direction I am going, what am I missing here? :S
