• construct graph from python set type.

  - by Vincent

  The sort question, is the an off the self function to make a graph from a set of python sets? The longer: I have several python set types. They each overlap or some are sub sets of others. I would like to make a graph (as in nodes and edges) with the edges weighted by common intersection of the sets. There are several graphing packages for python. (NetworkX, igraph,...) I am not familiar with the use of any of them. Will any of them make a graph directly from a list of sets ie, MakeGraphfromSets(alistofsets) If not do you know of an example of how to take the list of sets to define the edges. It actually looks like it might be straight forward but an example is always good to have.

• Where to start with C#

  - by RobertPitt

  Hello fellow programmers. Im a pretty experienced programmer in PHP and mainly web languages but today i have decided i want to start to learn a new language! Im only 21 and I feel as I will never make it in the programming industry without a great set of languages under my belt, So i decided to have a look at C#. The reason I have chosen C# is because some C programmers have told me that C# is the best language to learn for desktop applications. I think i need to get started with the Syntax / Structure of C#, What Development Environment to use, and other things that i might face along my new journey. I hope somebody can guide me Thanks.

• Using XTemplate with SimpleStore in Ext

  - by qui

  I am currently adding some functionality to some old code. There used to be a template which took a flat array of items and spat out some HTML, now the data is coming from a simple store which reads some JSON.. var allwords = [ ['abacteriano', 'abacteriano'], ['abacterial', 'abacteriano'], ['abciximab', 'abciximab'], etc.. So my simplestore goes like this: termStore = new Ext.data.SimpleStore({ fields: ['term', 'lookup'], data: allwords }); This definitly works fine as I use the termStore in a combobox. However I am having difficulty getting it to play with an XTemplate. It seems the syntax in extjs doesn't play well with SO, so this bit wont be in a code block... So I guess I'll describe it :p Essentially its a simple template which tries to get values out of the passed collection by doing {term} I then try and apply it by doing: tpl.overwrite(Ext.get("contentbox"), termStore); This gives me a JS error of "invalid object initializer"

• Teaching a mainframe COBOL programmer Java?

  - by Jared

  I’m trying to help someone learn Java who’s only programming experience is COBOL on the mainframe. I was wondering if anyone knew any good resources for object oriented concepts. I learned how to program with C++ so just understand the theory behind basic OOP. I’m more concerned about a way to get the basic concepts across, such as encapsulation and inheritance rather then Java syntax. I think it’d be better to teach the concepts of OOP then a language rather then trying to cram both a new language and paradigm in at the same time. Does anyone have any resources or ideas that could help this person learn OOP followed by Java?

• Searching for a source code editor component

  - by Iso5786

  Hi, I have to develop a program at work in which a consultant can enter a specification which is developed 2 years ago here in house. So i can't really tell what it is about. But the editor should support some standard functionality such as syntax highlighting, auto completion and maybe search & replace. I've searched for Java components but didn't find a good solution which matches my requirements. Anybody knows a good component? It doesn't matter in which language it is written but I prefer Java.

• C# - Dictionary with generic array as value

  - by alhazen

  In my class, I want to use a dictionary with the following declaration: Dictionary<string, T[]> Since the operations of my class are exactly the same for all generic types, I do not wish to define my class as generic (which means I would have to create a separate instance of my class for each generic type I insert into the dictionary ?). One alternative I'm attempting is to use Dictionary<string, object> instead: public void Add<T>(string str, T value) { // Assuming key already exists var array = (T[]) dictionary[str]; array[0] = value; } However, when iterating over the dictionary, how do I cast the object value back to an array ? foreach(string strKey in dictionary.Keys) { var array = (T[]) dictionary[strKey]; // How to cast here ? //... array[0] = default(T); } Thanks.

• Open source C compiler in C#?

  - by Dinah

  I've been getting into compiler creation. I've found some terrific beginner stuff and advanced stuff but nothing in the middle. I've created 3 different simple proof-of-concept compilers for toy languages but I want to expose myself to something real. The most straight forward real language in terms of syntax seems to be C. Since the language I'm most comfortable with right now is C#, I'd love to study the source code of a real non-tutorial C compiler written in C#. Does one (with source code available) exist?

• Doctrine: Relating a model to itself using a link table, like "This event is related to to the following other events"

  - by mattalexx

  So in English, the relationship would sound like "This event is related to to the following other events". My first instinct is to create an EventEvent model, with a first_event_id field and a second_event_id field. Then I would define the following two relationships in the Event model: $this->hasMany('Event as FirstRelatedEvents', array('local' => 'first_event_id', 'foreign' => 'second_event_id', 'refClass' => 'EventEvent')); $this->hasMany('Event as SecondRelatedEvents', array('local' => 'second_event_id', 'foreign' => 'first_event_id', 'refClass' => 'EventEvent')); But I would rather not have to use two relationships on the Event model. Is there a better way to do this?

• Compiler #defines for g++ and cl

  - by DHamrick

  I am writing a program that is cross platform. There are a few spots where I have to specify an operating system dependent call. #ifdef WINDOWS ..do windows only stuff #endif #ifdef LINUX ..do linux only stuff #endif Are there any preprocesser directives that get defined by the compiler so I don't have to explicitly define them when I use the command line compiler. ie. cl -DWINDOWS program.cpp or g++ -DLINUX program.cpp I realize I could easily write a makefile or have a shell/batch script that will do this automatically. But I would prefer to use the same ones as the compiler (if they exist) by default.

• Javascript recursive data structure definition

  - by Matt Bierner

  I need to define a data structure recursively in Javascript. Here is a simple example of a circular linked list: // List a very simplified example of what the actual (non list) code does. function List(f, r) { return function(){ return [f, r]; }; } var head = List('a', List('b', List('c', head))); When this is executed, head in List 'c' is resolved to undefined, not List 'a' as I need. List is an example function that returns a function (It is not an Javascript list that I can append to). I tried to wrap the definition of head is a self executing named function, but that blew the stack when head was resolved. What is the Javascript style solution that I am overlooking?

• ASP.NET JavaScript File Embeded In DLL With GZIP

  - by Lee Hesselden

  We have several fairly large JavaScript files embedded into a single script resources DLL. This is then consumed by multiple projects by way of a reference and page includes via the ASP.NET script manager. This keeps things nice and neat within our ASP.NET pages and requires very little work to integrate into new projects. The problem is that some of these script files are quite larger (approx 100KB) and take time to download. By running minify on them before embedding this is reduced down a lot (around 70KB) but not enough. What we would like to do is GZIP the files before they are embedded. However, just gzipping the files causes syntax errors as the content is not unzipped. There is a content type "text/javascript" applied in AssemblyInfo when the resource is embedded but we can't find a way to specify content-encoding. Is there any way to make this work without having to write a httpmodule/handler (which would mean changing the config for all consuming projects)?

• Accessing form's resources (resx file) from code

  - by kzen

  If I have a form Frm1.cs that is using some icons, images or other resources, these resources get stored in the form's resx file (Frm1.resx). My simple question is how do I access these resources from code? As a workaround I can store these resources in the Project resource file and they will be available via Properties.Resources.resourcename. However, similar syntax does not work for the resources stored in the form's resource file. While searching for a solution I have come across several references to ResourceManager class but was not able to find a way to use that to access the form's resources...

• Conditional Regex Replace in C# without MatchEvaluator

  - by Buttink

  So, Im trying to make a program to rename some files. For the most part, I want them to look like this, [Testing]StupidName - 2[720p].mkv But, I would like to be able to change the format, if so desired. If I use MatchEvaluators, you would have to recompile every time. Thats why I don't want to use the MatchEvaluator. The problem I have is that I don't know how, or if its possible, to tell Replace that if a group was found, include this string. The only syntax for this I have ever seen was something like (?<group>:data), but I can't get this to work. Well if anyone has an idea, im all for it.

• Advanced example-driven C book with a lot of code.

  - by Inso Reiges

  Hello, I am looking for a book on advanced C programming that: Teaches how to effectively express one's solution in C when one already knows the language in depth. Shows some common design idioms expressed in C, like encapsulation, modularity and that kind of thing. Is example-driven with a lot of good-quality code. I already know the language itself so books like otherwise wonderful "Expert C Programming" by Peter van der Linden is not really what i am looking for. What i need is a book on how to express my design in C, what are the common idioms, best practices, etc. I would also like to note that i am primarily interested in C, not C++, C#, Objective-C or any other languages inspired by C-like syntax. Thank you.

• Log information inside a JUnit Suite

  - by Alex Marinescu

  I'm currently trying to write inside a log file the total number of failed tests from a JUnite Suite. My testsuite is defined as follows: @RunWith(Suite.class) @SuiteClasses({Class1.class, Class2.class etc.}) public class SimpleTestSuite {} I tried to define a rule which would increase the total number of errors when a test fails, but apparently my rule is never called. @Rule public MethodRule logWatchRule = new TestWatchman() { public void failed(Throwable e, FrameworkMethod method) { errors += 1; } public void succeeded(FrameworkMethod method) { } }; Any ideas on what I should to do to achieve this behaviour?

• XNA 2d camera with arbitrary zoom center

  - by blooop

  I have a working 2D camera in XNA with these guts: ms = Mouse.GetState(); msv = new Vector2(ms.X, ms.Y); //screenspace mouse vecor pos = new Vector2(0, 0); //camera center of view zoom_center = cursor; //I would like to be able to define the zoom center in world coords offset = new Vector2(scrnwidth / 2, scrnheight / 2); transmatrix = Matrix.CreateTranslation(-pos.X, -pos.Y, 0) * Matrix.CreateScale(scale, scale, 1) * Matrix.CreateTranslation(offset.X, offset.Y, 0); inverse = Matrix.Invert(transmatrix); cursor = Vector2.Transform(msv, inverse); //the mouse position in world coords I can move the camera position around and change the zoom level (with other code that I have not pasted here for brevity). The camera always zooms around the center of the screen, but I would like to be able to zoom about an arbitrary zoom point (the cursor in this case), like the indie game dyson http://www.youtube.com/watch?v=YiwjjCMqnpg&feature=player_detailpage#t=144s I have tried all the combinations that make sense to me, but am completely stuck.

• Inline Conditional Statement in Stored Procedure

  - by Jason

  Here is the pseudo-code for my inline query in my code: select columnOne from myTable where columnOne = '#variableOne#' if len(variableTwo) gt 0 and columnTwo = '#variableTwo#' end I would like to move this into a stored procedure but am having trouble building the query correctly. I assume it would be something like select columnOne from myTable where columnOne = @variableOne CASE WHEN len(@variableTwo) <> 0 THEN and columnTwo = @variableTwo END This is giving me a syntax error. Could someone tell me what I've got wrong. Also, I would like to keep it to only one query and not just have one if statement. Also, I do not want to build the sql in the stored procedure and run Exec() on it.

• Regular expressions in python unicode

  - by Remy

  I need to remove all the html tags from a given webpage data. I tried this using regular expressions: import urllib2 import re page = urllib2.urlopen("http://www.frugalrules.com") from bs4 import BeautifulSoup, NavigableString, Comment soup = BeautifulSoup(page) link = soup.find('link', type='application/rss+xml') print link['href'] rss = urllib2.urlopen(link['href']).read() souprss = BeautifulSoup(rss) description_tag = souprss.find_all('description') content_tag = souprss.find_all('content:encoded') print re.sub('<[^>]*>', '', content_tag) But the syntax of the re.sub is: re.sub(pattern, repl, string, count=0) So, I modified the code as (instead of the print statement above): for row in content_tag: print re.sub(ur"<[^>]*>",'',row,re.UNICODE But it gives the following error: Traceback (most recent call last): File "C:\beautifulsoup4-4.3.2\collocation.py", line 20, in <module> print re.sub(ur"<[^>]*>",'',row,re.UNICODE) File "C:\Python27\lib\re.py", line 151, in sub return _compile(pattern, flags).sub(repl, string, count) TypeError: expected string or buffer What am I doing wrong?

• Vim or Emacs for software development

  - by Justin

  I'm not trying to start any wars here, just get some good info. I'm getting a little exhausted using numerous IDE's for development (VS, XCode, Eclipse/Netbeans, and TextMate) and am looking for a replacement I can use on all the different machines I interact with. What are some of the pros of Vim/Emacs for things like Languages supported Syntax highlighting (for things such as c, objc-c, c#, java, python, haskell, html, javascript, xml etc...) Code completion Code folding Working with a directory of files (like have a solution/project opened) Possible debugger support What are some of the main things you like about (Emacs/Vim, and please no flames only what you really like) Thanks =) *(yes.. I have scoured the net reading this vs that etc. but I'd like more of a 'why you love it' vs 'this is better than that because...')

• Template engine recommendations

  - by alex

  I'm looking for a template engine. Requirements: Runs on a JVM. Java is good; Jython, JRuby and the like, too... Can be used outside of servlets (unlike JSP) Is flexible wrt. to where the templates are stored (JSP and a lot of people require the templates to be stored in the FS). It should provide a template loading interface which one can implement or something like that Easy inclusion of parameterized templates- I really like JSP's tag fragments Good docs, nice code, etc., the usual suspects I've looked at JSP- it's nearly perfect except for the servlet and filesystem coupling, Stringtemplate- I love the template syntax, but it fails on the filesystem coupling, the documentation is lacking and template groups and stuff are confusing, GXP, TAL, etc. Ideas, thoughts?

• Efficiency of PHP arrays cast as objects?

  - by keithjgrant

  From what I understand, PHP objects are generally much faster than arrays. How is that efficiency affected if I'm typecasting to define stdClass objects on the fly: $var = (object)array('one' => 1, 'two' => 2); If the code doing this is deeply-nested, will I be better off explicitly defining $var as an objects instead: $var = new stdClass(); $var->one = 1; $var->two = 2; Is the difference negligible since I'll then be accessing $var as an object from there on, either way?

• Lazy evaluation with ostream C++ operators

  - by SavinG

  I am looking for a portable way to implement lazy evaluation in C++ for logging class. Let's say that I have a simple logging function like void syslog(int priority, const char *format, ...); then in syslog() function we can do: if (priority < current_priority) return; so we never actually call the formatting function (sprintf). On the other hand, if we use logging stream like log << LOG_NOTICE << "test " << 123; all the formating is always executed, which may take a lot of time. Is there any possibility to actually use all the goodies of ostream (like custom << operator for classes, type safety, elegant syntax...) in a way that the formating is executed AFTER the logging level is checked ?

• Attaching user data to AXObserver

  - by Ben Packard

  I am using an AXObserver to monitor when a window is closed. In the callback, I am just raising an NSNotification. All working well. What is the correct syntax for attaching some user data as refcon? The working call looks like this: err6 = AXObserverAddNotification(observerTable, tableRef, kAXUIElementDestroyedNotification, nil); and the callback specified when I create the observer has the signature: static void cbTableClosed (AXObserverRef observer, AXUIElementRef element, CFStringRef notification, void *refcon) I want to replace refcon with an object of my own, but don't know how to change either line. The obvious objective-c type changes through up warnings.
