• Why does OpenID look so hard to implement?

  - by user198729

  I read through this post: http://stackoverflow.com/questions/741345/how-do-i-implement-direct-identity-based-openid-authentication-with-zend-openid Why does it look so complicated to implement? IMO, it's just to send request to a remote site and retrieve the response. What's the problem those OpenID libraries are dealing with?

• How are partial methods used in C# 3.0?

  - by Eric Z Beard

  I have read about partial methods in the latest C# language specification, so I understand the principles, but I'm wondering how people are actually using them. Is there a particular design pattern that benefits from partial methods?

• Creating a "virtual" path (/bla) in Mac OS X and Linux that calls custom code

  - by Michael Stum

  Just something I'd like to play with, I would like to create a "virtual" file/directory in the File System of Linux or Mac OS X (Not sure if I can share the same code - does POSIX help?), for example /foo and then perform custom code when something is read or written to it. Similar how /dev/null allows for stuff like echo "Hello!" > /dev/null I don't care if it's in /dev, /proc or anywhere else, as said it's mainly something to play with...

• Encrypted HTML page without HTTPS

  - by Tichomir Mitkov

  I have a Perl script to open this page http://svejo.net/popular/all/new/ and filter the names of the posts but except headers everything seems encrypted. Nothing can be read. When I open the same page in a browser everything looks fine including the source code. How is it possible to encrypt a page for a script and not for a browser? My Perl script sends the same headers as my browser (Google Chrome).

• How can I use the eclipse indenter from my code?

  - by Geo

  I noticed the eclipse indenter has support for the latest version of java, and it would be nice if I could use that class to indent generated java source code. Is there a way of integrating it ? EDIT: I need to be able to include the code formatter in my code. No external calls. EDIT2: I've managed to get it working. You can read the story here. Thanks VonC !

• MP3 and OGG tags in PHP

  - by Quamis

  Except http://us3.php.net/manual/en/book.ktaglib.php and http://getid3.sourceforge.net/ does anyone know of any other way to work from PHP with tags on audio files? I need to read and write them, and KTagLib seems a little too much for the job, and also don't really get the documentation, and getID3 seems to only write ID3v1 tags.

• Why can't my function access a variable in an enclosing function?

  - by nailer

  I know about the LEGB rule. But a simple test of whether a function has read access to variables defined in an enclosing function doesn't seem to actually work. Ie: #!/usr/bin/env python2.4 '''Simple test of Python scoping rules''' def myfunction(): print 'Hope this works: '+myvariable def enclosing(): myvariable = 'ooh this worked' myfunction() if __name__ == '__main__': enclosing() Returns: NameError: global name 'myvariable' is not defined Am I doing something wrong? Is there more to it than the LEGB resolution order?

• Is or Are to prefix boolean values

  - by Brian T

  When naming a boolean, or a function returning a boolean it's usual to prefix with 'is' e.g. isPointerNull isShapeSquare What about when refering to multiple items, should it be: arePointersNull or isPointersNull areShapesNull or isShapesNull I can see arguments for both; is offers consistency and perhaps slightly better readability, are makes the code read in a more natural way. Any opinions?

• python on the web, does it compile down to bytecode or is it more like php?

  - by Blankman

  Does python compile down to some byte code or is it rendered on the fly each time like php/asp? From my readings I read it has its own byte code format, so i figured it was like java/.net where it compiles into a intermediate language/byte code. so it is more effecient in that respect that php right?

• Why does trying to understand delegates feel like trying to understand the nature of the universe?

  - by Kin

  I've read two books, tons of examples. They still make next to no sense to me. I could probably write some code that uses delegates, but I have no idea why. Am I the only one with this problem, or am I just an idiot? If anyone can actually explain to me when, where, and why I would actually use a delegate, I'll love you forever.

• How to set session timeout dinamically in java web applications?

  - by Jonathas Carrijo

  Hi, I need to give my user a web interface to change the session timeout interval. So, each installation of the application might have different timeouts for their sessions, but they web.xml cannot be different. Is there a way to set the session timeout programatically, so that I could use, say, ServletContextListener.contextInitialized() to read the configured interval and set it upon application startup? Thanks a lot.

• Finding all CLASSPATH resources matching a pattern

  - by binil

  I want to read a bunch of text files, by loading them as resources using the context classloader. URL url = Thread.currentThread() .getContextClassloader() .getResource("folder/foo.txt"); Is there some way to get a list of resources whose names match a given pattern? For eg: URL[] matchingUrls = someLibrary.getMatchingResources("folder/*.txt"); Libraries like Spring can scan the classpath to find classes with a given annotation, so I am wondering if there something similar to load a bunch of resources.

• Is there a memory efficient and fast way to load big json files in python?

  - by user210481

  I have some json files with 500MB. If I use the "trivial" json.load to load its content all at once, it will consume a lot of memory. Is there a way to read partially the file? If it was a text, line delimited file, I would be able to iterate over the lines. I am looking for analogy to it. Any suggestions? Thanks

• Unnecessary code...

  - by Martin Milan

  Suppose I have some code that looks like this: Private Sub MySub() dim blnFlag as Boolean blnFlag = False for each item in collection if item.Name = "Mike" then blnFound = true exit for endif next item End Sub Now - the blnFLag = False assignment is not actually necessary - booleans are initialised as false, but I think it's inclusion makes the code easier to read. What's your opinion?

• What is the most performant 2D graphics engine for use with Android?

  - by nbolton

  I have managed to make a hello world JBox2D application, and it works (I have some bouncing balls). However, I just read a comment on a forum post, which claims that JBox2D produces a lot of garbage, and so causes animation to be poor. Is this true? If yes, then what other 2D engines are available to me? I would very much like to use a physics engine for my 2D game, even if it's just a very simple one.
