• How to use #ifdef entities as part of functions in header files

  - by Crazyjavahacking

  I would like to ask if it is possible to use the entities defined in #ifdef block in header files. To be clear, I have following code: #ifdef #include <winsock2.h> #define SOCKET_HANDLE SOCKET #define CONNECTION_HANDLE SOCKET #endif SOCKET_HANDLE createServerSocket(const char* hostAddress, short port); I am Java developer and this seems completely fine for me. However compiler has a problem with this. Can you explain why is that code a problem? Also how can I force to compile it. (The idea is to have generic interface and conditional compilation to determine real types according to running platform at compile time.) Thanks

• Are there any well-known algorithms or computer models that computer scientists use to predict FIFA

  - by Khnle

  Occasionally I read news articles that mention about some computer models that computer scientists use to predict winners of some sporting events or the odds for betting which I think there must be a mathematical model behind it. I never bothered to think twice even though I am a "pseudo computer scientist" myself. With the 2010 FIFA World Cup just underway, and since I am also a "pseudo football/soccer player" myself, I just started to wonder about these calculations algorithms. For example, I know one factor is determining the strength of opponents, so that a win against a strong opponent can count more than a win against a weak opponent. But it now kind of gets in a circular loop, or at least how does one determine the strength of a team in the first place, before that team can be considered strong or weak? If it's based on a historical data then there's no way that could be accurate, because those players of the past are no longer on the fields so their impact is none (except maybe if they become coaches like Maradona) Anyway, long question short, if you're happen to be working in this field or have some knowledge, please shed some lights.

• How to test if an array contains a pair of numbers whose product is odd?

  - by John

  How can I write a function that takes an array of integers and returns true if their exists a pair of numbers whose product is odd? What are the properties of odd integers? And of course, how do you write this function in Java? Also, maybe a short explanation of how you went about formulating an algorithm for the actual implementation. Yes, this is a function out of a textbook. No, this is not homework—I'm just trying to learn, so please no "do your own homework comments."

• what are most important things that i must know in order to jump into silverlight development

  - by Poni

  I have vast programming knowledge; C++/C#/ActionScript/ASM/PHP..... so learning the language of SilverLight itself isn't of an issue. To keep long story short, when asking this question I'm asking it as a developer who's coming from Flash world - great graphics/sounds/media support, fully cross-platform, ability to combine several SWFs within a "movie" (which also implies code reusability). A Flash developer have pretty much freedom. What are most important things that i must know in order to jump into silverlight development? Did you already make the move to SilverLight from Flash yourself? Are you a "guru" at both? Great, let's hear what you have to say - developer to developer! =)

• Select only the first rows for each unique value of a column in R

  - by dmvianna

  From a dataframe like this test <- data.frame('id'= rep(1:5,2), 'string'= LETTERS[1:10]) test <- test[order(test$id), ] rownames(test) <- 1:10 > test id string 1 1 A 2 1 F 3 2 B 4 2 G 5 3 C 6 3 H 7 4 D 8 4 I 9 5 E 10 5 J I want to create a new one with the first appearance of each id / string pair. If sqldf accepted R code within it, the query could look like this: res <- sqldf("select id, min(rownames(test)), string from test group by id, string") > res id string 1 1 A 3 2 B 5 3 C 7 4 D 9 5 E Is there a solution short of creating a new column like test$row <- rownames(test) and running the same sqldf query with min(row)?

• Unboxing object containing a value which is known to be assignable to an integer variable

  - by Wim Coenen

  If I have an object instance and I know it is actually a boxed integer, then I can simply cast it back to int like this: object o = GetSomethingByName("foo"); int i = (int)o; However, I don't actually know that the value is an integer. I only know that it can be assigned to an integer. For example, it could be a byte, and the above code would throw InvalidCastException in that case. Instead I would have to do this: object o = GetSomethingByName("foo"); int i = (int)(byte)o; The value could also be a short, or something else which can be assigned to an int. How do I generalize my code to handle all those cases (without handling each possibility separately)?

• How do you deal with the more mundane parts of programming tasks?

  - by Uri

  My experience as a developer is that many projects or tickets are a mix of a short and focused very interesting task (e.g., designing some API or a platform to solve something) and a lot of repetitive and mundane tasks that cannot be automated (such as certain refactorings to use the API or platform, implementation of certain tests, some GUI handling, etc). I believe that this is the nature of our profession, unless we are high-level architects or managements and can delegate this work. The only item in my personal arsenal when dealing with these tasks is to devote some of my attention to radio or audiobooks (preferably not in English as I find it hard to concentrate on two "streams" of English at the same time). I maintain sufficient attention to carry the task and don't lose concentration as fast. I'm wondering how others cope with these and maintain concentration.

• Need help with Excel 2007 Formula - Many to many update

  - by Monica

  I'm experienced with database development, but not so much with Excel. I'm looking for help writing an Excel formula that would help my client's spreadsheet behave like a database. This is what I'm looking to do, but I can't figure out how to write it in Excel 2007: "If Q4 (on sheet 2) contains A2 (on sheet 1), append A1 (on sheet 1) with Q5 (on sheet 2)" Some factors: 1) This formula may find multiple instances of A2, so it should not stop after finding the first match 2) The values, as they are created in A1, should be separated with comma and space 3) This is a many to many relationship between Q4 and A2 Thanks for any help with this. I've tried vlookups, match, if statements, but they all fall short in one way or another.

• C++ / Java: Toggle boolean statement?

  - by Martijn Courteaux

  Hi, Is there a short way to toggle a boolean? With integers we can do operations like this: int i = 4; i *= 4; // equals 16 /* Which is equivalent to */ i = i * 4; So is there also something for booleans (like the *= operator for ints)? In C++: bool booleanWithAVeryLongName = true; booleanWithAVeryLongName = !booleanWithAVeryLongName; // Can it shorter? booleanWithAVeryLongName !=; // Or something? In Java: boolean booleanWithAVeryLongName = true; booleanWithAVeryLongName = !booleanWithAVeryLongName; // Can it shorter? booleanWithAVeryLongName !=; // Or something?

• How to detect first or last element iterating over a container?

  - by Basilevs

  How to do the following in more stylish/short way? for(i=container.begin(); i!=container.end(); ++i) { if (i!=container.begin()) { cout << ", "; } cout << *i; if (i==container.end()) { cout << "!" << endl; } } Solutions like foreach are acceptable (actions on first and last elements need to be configurable, though).

• Send JSON object via GET and POST in php without having to wrapping it in another object literal.

  - by Kucebe

  My site does some short ajax call in JSON format, using jQuery. At client-side i'd like to send object just passing it in ajax function, without being forced to wrap it in an object literal like this: {'person' : person}. For the same reasons, at server-side i'd like to manage objects without the binding of $_GET['person'] or $_POST['person']. For example: var person = { 'name' : 'John', 'lastName' : 'Doe', 'age' : 32, 'married' : true } sendAjaxRequest(person); in php, using: $person = json_decode(file_get_contents("php://input")); i can get easily the object, but only with POST format, not in GET. Any suggestions?

• OpenGL game written in C with a Cocoa front-end I want to port to Windows

  - by Philip

  Hello, I'm wondering if someone could offer me some tips on how to go about this. I have a MacOS X OpenGL game that is written in very portable C with the exception of the non-game-play GUI. So in Cocoa I set up the window and OpenGL context, manage preferences, registration, listen for keystrokes etc. But all of the drawing and processing of input is handled in nice portable C. So I want to port to Windows. I figured the obvious way to go about was to use the Win32 api. Then I started to read a primer on Win32 and began to wonder if maybe life isn't too short. Can I do this in C# (without converting the backend to C#)? I'd rather devote the time to learning C# than Win32. Any suggestions would be most welcome. I really don't know a lick about Windows. The last version I regularly used was 3.1...

• Shorter GUIDs than hashing a user id?

  - by Alex Mcp

  I'm wondering how Instapaper (bookmarklet that saves text) might generate URLs for their bookmarklet. Mine has a script src of something similar to www.instapaper.com/j/AnJHrfoDTRia The quality of these URLs is that they need to never collide, and not be really guessable (so other people can't save to your account). I know a simple approach might be to MD5 their email address (presumed to have been checked on signup for uniqueness), but then I'd end up with a super long string. This isn't a huge issue, but I'm wondering what techniques there are for shorter GUIDs that won't collide too often (this is obviously the tradeoff, but 12 characters above is pretty short in my opinion)

• Float32 to Float16

  - by Goz

  Can someone explain to me how I convert a 32-bit floating point value to a 16-bit floating point value? (s = sign e = exponent and m = mantissa) If 32-bit float is 1s7e24m And 16-bit float is 1s5e10m Then is it as simple as doing? int fltInt32; short fltInt16; memcpy( &fltInt32, &flt, sizeof( float ) ); fltInt16 = (fltInt32 & 0x00FFFFFF) >> 14; fltInt16 |= ((fltInt32 & 0x7f000000) >> 26) << 10; fltInt16 |= ((fltInt32 & 0x80000000) >> 16); I'm assuming it ISN'T that simple ... so can anyone tell me what you DO need to do?

• Comparing two speech sounds

  - by JessicaB

  I need to be able to determine if two sounds are very similar. The goal is to have a very limited vocabulary (10 or 15) of short one or two syllable words, then compare a captured sound to determine if it is one of those items with all the usual variability in environmental and capture conditions. The idea is that the user can issue a few simple commands by voice instead of keyboard or mouse. Does anyone know the best approach to this? I don't want to do full blown speech recognition, just something much more limited.

• Clear all currently defined vim macros

  - by Simon Walker

  Hi everyone I have a vim macro that I keep mistyping, usually when I'm trying to save something so I do it quickly and I can't work out what keys I pressed. It is annoying as it pastes some irrelevant bash code into my file so I have to undo the erroneous pasting which also undos the last thing I typed that I do want. I was looking for a way to either list the currently defined macros (so I can redefine the offending one), or a way to clear out them completely. I only use macros in the very short term so I don't mind losing them all. Cheers

• In Eclipse, how do I change the default modifiers in the class/type template?

  - by gustafc

  Eclipse's default template for new types (Window Preferences Code Style Code Templates New Java Files) looks like this: ${filecomment} ${package_declaration} ${typecomment} ${type_declaration} Creating a new class, it'll look something like this: package pkg; import blah.blah; public class FileName { // Class is accessible to everyone, and can be inherited } Now, I'm fervent in my belief that access should be as restricted as possible, and inheritance should be forbidden unless explicitly permitted, so I'd like to change the ${type_declaration} to declare all classes as final rather than public: package pkg; import blah.blah; final class FileName { // Class is only accessible in package, and can't be inherited } That seems easier said than done. The only thing I've found googling is a 2004 question on Eclipse's mailing list which was unanswered. So, the question in short: How can I change the default class/type modifiers in Eclipse? I'm using Eclipse Galileo (3.5) if that matters.

• Why would Django fcgi just die? How can I find out?

  - by Joe

  I'm running Django on Linux using fcgi and Lighttpd. Every now and again (about once a day) the server just dies. I'm using the latest stable release of Django, Python and Lighttpd. The only thing I can think of is that my program is opening a lot of files and executing a lot of external processes, but I'm fairly sure that side of things is watertight. Looking at the error and access logs, there's nothing exceptional happening (i.e. load isn't above normal). On those occasions where I have had exceptions from Python, these have shown up in the error.log, but when this crash happens I get nothing. Is there any way of finding out why the process died? Short of putting logging statements on every single line? Obviously I can't reproduce this so I don't know exactly where to look.

• iPhone: different icon for homescreen and App Store

  - by arne_

  I would like to know if the app icon on the iPhone can be slightly different than the one shown in a large version in Apple's App Store. It was discussed in short here: http://stackoverflow.com/questions/28551/tips-for-a-successful-appstore-submission/266657#266657 But I wanted to make sure if anyone has more experience with that. To give an example: The New York Times has many words incorporated in its app icon (see http://itunes.apple.com/de/app/nytimes/id284862083?mt=8). Would it be okay to have a full black colored background without the words in the small/homescreen version of the icon?

• How do I use Ajax and Jquery to get an array from PHP and post it?

  - by Jared

  Hello, I am using a separate PHP file as a configuration file for everything else on a basic ecommerce site. $product1["short"] = "product one"; $product1["menuimgslideshowsrc"] = "image/product1.jpg"; When I hover over a button, I want to get $product1["menuimgslideshowsrc"] and swap it out with an IMG SRC. I can do the swapping no problem, I need to know how to get the information stored in $product1["menuimgslideshowsrc"]. I assume I would use Ajax, but I am open to other ideas. Thanks in advance.

• how can I reliably check that requests to my service file have come from my website?

  - by woot586

  I have a service.php class that I use to service AJAX calls from my website. To prevent other people accessing the service using PHP CURL I would normally check the request has come from mysite, and if they are not then just redirect to my home page e.g. if($_SERVER['HTTP_REFERER'] != "http://www.mysite.com"){ header('location: http://www.mysite.com'); exit; } I read in the PHP holy bible: http://www.php.net/manual/en/reserved.variables.server.php that "Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted." So if this method is not reliable, my question is how can I reliably check that requests to my service file have come from my website? Thanks for any help you can provide!

• Render multiple layers in XNA

  - by Charles

  I'm using XNA, and I've run into a little problem. I need to support multiple layers, each with a distinct z order (I call these "viewports"). A picture is worth a thousand words, so here's what it should look like: There are several things to notice here. Sprites do not render outside of their viewport, as you can see with Sprite B. Also, notice how the viewports are rendered - it's very similar to "layers" in Photoshop. Although Sprite C is has a z order of -1000, C still renders above Sprite A because its viewport's z-order is a greater than A's viewport's z-order. There's one last detail that I couldn't display very well in the above picture. Each viewport needs to optionally render a color over its region of the screen - you could think of it as a "tinting" affect. I'm completely at a loss when it comes to doing this the best way in XNA, so I could really use a short snippet of C#/VB.NET code that demonstrates this in action. Any help would be greatly appreciated.

• Get data from database with two conditions in one list

  - by Kreeki

  Hi coders out there, I'm new to this. I have a (sqlite3, but with ActiveRecord it doesn't matter) table called Messages and a model called Message. I want to find all messages in database that have user_id or reciever_id equal to the object user and his attribute id (for short user.id). I know it's probably just one simple line of code, but I wanna do it the right "rails" way and I don't have much experience with this. I'm using Rails 3. Thanks for any help. Cheers
