#define Constant const
#define Integer int
#define Real double
#define Boolean bool
#define Character char
#define String string;
#define System system

I know because netbeans provides native support for springs and hibernate, it is meant to be better.
I don't mind changing my IDE if i get better support for struts2!
So my questions are
- Please list all the free IDEs where native support for struts2 is provided. And if possible please compare them.
- Please list all the plugins that are available for eclipse for struts2 development. I have heard there are better plugins in eclipse.
- Also, if there are better plugins in any other IDE (other than netbeans or eclipse of course), please list them giving links.
- Please give me some tips which I'll need before starting a full blown project in Struts2. I haven't worked on any project on Struts2. I have just finished reading [Struts 2 in Action][1] of Manning publications.

def findword():
letters = set(str(raw_input("Type letters: ")))
for item in wordlist: # already defined list containing the words
if letters >= set(item):
if len(item) <= len(letters):
print item
I am using set to compare the letters with the list of words.
The problem is that the output can be words containing two of the same letter even though input may only contain one of that specific letter. So how can I make sure the output will be the exact input letters but not arranged the same way?
I'd appreciate if you would take the time to help me out with this! Thanks!

The process should preserve the directory structure from the output of each test project. We have a solution that requires manually attaching test projects to a master project, but our solution has far too many projects for this to be maintainable. These should be located automatically based on naming convention (x.UnitTest.csproj, y.IntegrationTest.csproj).
For background, we are working with a build system that passes artifacts (binaries, etc) between agents. We are compiling on one agent, and testing on other agents. The massive duplication of assemblies between test projects is slowing the build process down.
What I have done:
1) I have a csproj that references most of the test projects. This gets binaries and dependencies into one folder.
2) I am able to identify all files to copy using this
<CreateItem
Include="%(ProjectReference.RootDir)%(ProjectReference.Directory)$(OutDir)*.config">
<Output TaskParameter="Include" ItemName="TestConfigurationFiles"/>
</CreateItem>
<Copy
SourceFiles="@(TestConfigurationFiles)"
DestinationFolder="$(OutDir)">
</Copy>
I've attempted most obvious things, such as
- MsBuild task: RebaseOutputs attribute, overriding the OutDir property. I can provide the msbuild task with a dynamically generated set of outputs, but can only build them in their default folder.
- Hooking into the TargetOutputs of
msbuild task gives only the primary
output assembly (without
dependencies).
- I experimented with "Copy Always" for
configuration files. This puts them
in the output directory of the
dependent project as "app.config" not
"dllname.config", and not in the
final project.
Solutions that could make this better might include
- Provide an example of adding to the projectreference item array dynamically, before compilation.
- Use msbuild TargetOutputs to create a list of all files in the folder (instead of just the primary output) and copy to a destination folder.
Today I'm using msbuild 3.5. Ideally the solution would work with msbuild 3.5. We are transitioning to .NET 4 / MsBuild 4 soon, so, if must be done in .Net 4, that is fine.

dataPtr is the previously malloced array of data bytes for the image,
dataLen is the number of bytes in the dataPtr array, and
callbackFunc is as described in the CGDataProviderCreateWithData documentation:
void callbackFunc(void *info, const void *data, size_t size);
The callback function is called when the data provider is released so I could free() dataPtr there, but I may want to continue using it (dataPtr) and at some later stage free it. This block of code will be called multiple times, and the flow will look something like:
1. malloc(dataPtr)
2. create image (call CGDataProviderCreateWithData etc)
3. display image
4. release image (and so release data provider created by CGDataProviderCreateWithData)
5. continue to use dataPtr
6. free(dataPtr)

The problem is that I can't free(dataPtr) in the callback from CGDataProviderCreateWithData because I still want to use it, so I want to free it some time later - and I can't free it until I know that the data provider no longer needs it (as far as I can tell CGDataProviderCreateWithData uses the array I pass, it doesn't take a copy).
I can't do (1) above until I know it is ok to free and re-malloc dataPtr, so what I really want to do is block waiting for the data provider to be freed (well, I want to know whether I should re-enter the 1..6 block of code, which I can't do until the data provider is freed). It will be - I create the data provider, create the image and immediately display it and release the data provider. The trouble is that the data provider isn't actually released until the UIImage is released and is finished with it.

As I understand it when I say `#include <stdio.h>` it grabs stdio.h from the default location...usually a directory inside your working directory called include. How do I actually get the file stdio.h? Do I need to download a bunch of .h files and move them from project to project inside the include directory? I did the following in a test.c file. I then ran make test and it outputted a binary. When I ran ./test I did not see hello print onto my screen. I thought I wasn't seeing output maybe because it doesn't find the stdio.h library.

-If I click on the eye icon of layer A, activate the eye icon of layer B, AND C, AND D simultaneously...
-activate the eye Icon of layer A OR B OR C... but don't allow to have more than one visible layer at the same time...
Grouping layers does not fit my purposes because I want to do that between layers that already belong to different groups.
Thanks! | visibility | photoshop | layer | null | null | 01/13/2012 20:35:35 | off topic | Photoshop - How to link layers visibility (not position)?

Using test driven development, I am used to writing tests and then actual functionality. What works well for me it to write the test, run the function with some debug output to see that state of variables until the unit test passes, and then moving the debug output.
In grails the 'grails test-app', the output of 'log.debug' and 'println' is not recorded to the console, and it is not in the reporting either.
The documentation point to using mocklogging, which should output the log.debug calls to the console, but using grails 1.2.1, I can not see any output.

The Media Query functionality seems perfect and my initial testing bears this out. The question I have is: with phones and tablets that change their orientation from portrait to landscape (upon rotation of the device) what does max-width then refer to?
In other words, the bigger Android phones have resolutions along the lines of 480x800, the iPhone4 has a resolution of 640x960, and the original Blackberry Torch has a resolution of 360x480. These are all the resolutions (W x H) when the devices are held in portrait mode, so the widths are 400, 640, and 360 respectively. However, when you rotate the device to landscape, the height 'becomes' the width for display purposes. So the effective widths in landscape then become 800, 960, and 480 respectively, and the 800 and 960 widths overlap with tablet landscape widths which messes up the display.
So, is width always width? That is to say, when the device reports its dimensions, does the width value always stay the same for CSS purposes, or does the width value change when the device rotates to landscape?
Thanks to you all in advance. | css3 | media-queries | null | null | null | null | open | CSS Media Queries

Basically many years back I used to work at a mutual fund and we used different tools to select optimize portfolios as well as hedge existing ones. We would take these results and make our own modifications then sell them to clients. After my company downsized, I decided I wanted to give it a try(to create the software and include my customizations) but I have no clue how combinations are actually generated for the software.
After 6 months of trying, I'm accepting that my approach is impossible. I was trying to use combination algorithms like from Knuth's book, as well as doing bit combinations to try to find every possible portfolio(I limited it to 30 stocks) on the NYSE(5,000+ stocks). But as per everyone I have spoken to this will take me billions of billions of years to just get one days results.
So what am I missing? We would enter our risk tolerance and view of the market(stock market growth expectations, inflation expectations, fed funds expectations,etc..) and it would give us the ideal portfolio(in theory..). With thousands of possibilities and quadrillion possible combinations of weights of stocks, how are they able to calculate results so quickly(or even at all)? As the admin of the system, I know we downloaded a file everyday(less than 100 mb and loaded in a mssql database..so its not like we had every possibility, I would get a 5 gig file in a min of doing my combination algo) and the applications worked offline(so it must have been doing it locally on the desktop/laptop cpu not on a massive supercomputer somewhere and took a min or two to run..15 minutes was the longest for a global fund which includes every stock in the world). Its so confusing because their work required correlation of the entire fund to be good(I don't think they were just sending the top stocks they pre-calculated because everyone got different results). So I wanted a 30 stock fund that gave me 2% returns and had a negative correlation with the market, and was 60% hedged how could the software generate that information? note, I'm not asking about the math or the finance part, I'm asking how it was able to generate 30 stocks from the entire market that gave 2% returns when in order to do that it would need to know the returns of all 30 stock portfolio(That alone would make it run for billions of years, right? the other restrictions make it more complex).
So How is this being done programmatically? I'm starting to believe they are not using Knuth's combination algorithm to generate every possibility yet their results don't seem randomly selected and individually selecting the stocks seems to miss the correlation part. How can so many investment softwares do things like this? It seemed like nothing when using the program but after trying to create my own it seems impossible(which its not because people are using it). | algorithm | math | statistics | finance | portfolio | 05/21/2012 11:13:02 | not constructive | How do portfolio software generate their portfolio suggestions so quickly when the possibilities are huge?

I wrote a little code to get some exerice in C++...
The code works... but it has a little problem... if you want to solve the problem go ahead and read, if you don't want to please comment on the programming style, I need it to improve myself.
The game is called "Stress in camisa",
is a card game from my region in Italy...
the game is a really simple luck game , I played it when I was 4... The rules are simple:
distribute all the 52 card of a French deck between two player,
each player in a row discard the card on top of the hand in the center of the table ,
if one card is less then three,
the other player has to give a corresponding number of cards to the number reported on the card...
if the other player throw the cards in a row without having a card less then 3, the other player get all the cards that are in the center of the table.
loses who don't have anymore cards in his hand.
Example
"firs turn"
player 1:
King of Spades
player 2:
Queen of Clubs
player 1:
3 of Diamond (>now player2 has to discard 3 cards)
player 2:
Jack of Hearts
8 of Clubs
6 of Diamond
player 1 won and take:
King of Spades
Queen of Clubs
3 of Diamond
Jack of Hearts
8 of Clubs
6 of Diamond
"second turn"
player 2:
2 of Clubs (> player 1 has to throw 2 cards)
player 1:
King of Clubs (> 1st card)
2 of Diamond (> 2nd card is less then 3 so player 2 has to throw 2 card)
player 2:
5 of Hearts (> 1st card)
Jack of Diamond (> 2nd card)
player one whon again, and takes:
2 of Clubs
King of Clubs
2 of Diamond
5 of Hearts
Jack of Diamond
**To the code**
I defined the function to check if the card is thrown is < 3 and to make the other player throw the corresponding number of card like this:
void check(Card card, Hand &g1, Hand &g2, Hand &Deck_c){
cout << endl;
int a = card.get_number();
if (card.get_number() <= 3) {
cout << g2.get_name() << " discard: " << endl;
while (a > 0) {
if (g2.void_hand()) {
return;
}
Card discarded_card = g2.discard(0);
cout << " ";
cout << discarded_card;
Deck_c.append_card(discarded_card);
check( discarded_card, g2,g1, Deck_c);
a--;
}
int size_Deck_c = Deck_c.size_cards();
for (int i = 0; i < size_Deck_c; i++) {
g1.feed_from_back(Deck_c.discard(0));
}
return;
}
return;
}
it works fine if there is only one card less then 3 in play:
Giovanni discard:
2 of Heart
Pietro discard:
8 of Clubs
7 of Heart
but here is the problem:
Pietro discard:
3 of Heart
Giovanni discard:
2 of Spades
Pietro discard:
Queen of Spades
5 of Spades (>should pass the turn but continue to throw cards)
5 of Diamond
9 of Diamond
Pietro should discard 2 card, then pass the turn....
the function is a recursive function, which check if the card is less then 3 every card is thrown
if it's over 3 it return to the normal game,
else it call again the function with switched players...
The problem is in that iterator "int a"...

it works fine if there is only one card less then 3 in play:
Giovanni discard:
2 of Heart
Pietro discard:
8 of Clubs
7 of Heart
but here is the problem:
Pietro discard:
3 of Heart
Giovanni discard:
2 of Spades
Pietro discard:
Queen of Spades
5 of Spades (>should pass the turn but continue to throw cards)
5 of Diamond
9 of Diamond
Pietro should discard 2 card, then pass the turn....
the function is a recursive function, which check if the card is less then 3 every card is thrown
if it's over 3 it return to the normal game,
else it call again the function with switched players...
The problem is in that iterator "int a"...

Where do they save the user names and passwords?
and How do i save the user name and the password that is entered through submit button in some other file?

because searching and sorting techniques are powerful with the above scripts.I dont know how to use them in HTML and also the question is,can we use them in HTML?
Please let me know How to make it through.And can we also redirect to some links when we use click button and push buttons ? | html | html5 | null | null | null | 07/23/2011 22:41:03 | not a real question | Question on submit and push buttons. and also the scripting language in HTML

The method `getActiveSlides()` will return the slides (as an array) currently activated for my application. What's import is that I am getting the number of slides that are active. For anything over 1 active slide, the loop above does not work. If I have 3 active slides (for example), it will only call the `.trigger()` method once. Within my click handler, if I instead use:
$("#studentWrapper").trigger("click");
$("#studentWrapper").trigger("click");
$("#studentWrapper").trigger("click");
It will work just fine. The problem is that I don't know how many times I'll need to call the `.trigger()` method so I am unable to do this manually.

The calendar will start on today when loaded and the user can then swipe left to get to tomorrow or right to get to yesterday, continuing to swipe in either direction for as far as they want.
The final statement there is the problem. Is there a way to use ViewPager with an unlimited number of views? I've tested my base code and have been able to set the total number of views to 10,000 and asked the pager to start me on page 5,000 and it works completely fine.
As long as there are no memory concerns, I may just go this route, anticipating that the user will not likely swipe 5,000 days in either direction.
ViewPager is an awesome gift for Android developers, so I'll find a way to use it. Who else is using it and are you using it with a large amount of views?

I'm asking myself two questions:
1) should i take the soft to C language ? +: speed -: harder to develop, to run. I don't talk about garbage collector since i don't use it very much.
2) keep the soft in Java, just change code for less heap memory usage: Use arrays contained in classes instead of (LARGE) collections of complex objects. ( i used that technique in ZBuffer implementation : Memory Usage -- Speed +++)

It is the same situation with the second and third view controller. When I try to transfer between the first to second to third and then back to first, it does not work.
