• Is recursion generally considered to be an outdated method of traversing compared to using a stack?

  - by Jamie Dixon

  I've been reading in a couple of places where people are opting to use a Stack instead of recursion. Is this because recursion is seen as being an outdated way to get-the-job-done or are both methods equally applicable in different contexts?

• StructureMap for Silverlight

  - by David Whitten

  Hey fellow coders, Has anyone tried to port the current StructureMap source to work with Silverlight? I know there are other IOC containers for Silverlight like Unity, Ninject, and a few others, but I particularly like the ease of use with StrutureMap. Anyways, I'm on a quest at the moment to get it working with SL. Let me know your thoughts if this is really worth doing? Seems like something fun to do. Thanks, David

• Twisted Python getPage

  - by David Dixon II

  I tried to get support on this but I am TOTALLY confused. Here's my code: from twisted.internet import reactor from twisted.web.client import getPage from twisted.web.error import Error from twisted.internet.defer import DeferredList from sys import argv class GrabPage: def __init__(self, page): self.page = page def start(self, *args): if args == (): # We apparently don't need authentication for this d1 = getPage(self.page) else: if len(args) == 2: # We have our login information d1 = getPage(self.page, headers={"Authorization": " ".join(args)}) else: raise Exception('Missing parameters') d1.addCallback(self.pageCallback) dl = DeferredList([d1]) d1.addErrback(self.errorHandler) dl.addCallback(self.listCallback) def errorHandler(self,result): # Bad thingy! pass def pageCallback(self, result): return result def listCallback(self, result): print result a = GrabPage('http://www.google.com') data = a.start() # Not the HTML I wish to get the HTML out which is given to pageCallback when start() is called. This has been a pita for me. Ty! And sorry for my sucky coding.

• Why is my ASP.NET app slow the first time after building a class library?

  - by David

  Hi all I've got a web app solution containing a class library project. Whenever I rebuild the class library and then refresh the page, it takes ages the first time, and is then quick again subsequently. It's almost as if the newly rebuilt dll is having to 'bed in' to the app. Can anyone tell me what's really going on behind the scenes? Thanks David

• Weird .htaccess password request that I didn't make...

  - by Dixon Crews

  Okay. So I went on a trip, came back, and suddenly, a website that I was working on is now asking for a username and password á la .htaccess. Thing is, I never made this happen and there is no .htaccess file anywhere to be found. Here is the site: link I didn't buy the template from omegathemes.com, whatever that is. And when you go there, it asks for the same kind of user and password. Any help?

• How to reliably retrieve tables and columns information stored in Torque Criteria object

  - by David Zhao

  Hi there, Is there a way to retrieve tables, including alias tables, and columns, including alias columns, from an Apache Torque Criteria object reliably? I understand that there is methods like: getSelectedColumns, getAsColumns(), getJoins(), etc., but for examples, getJoins() will just return a list of joined tables strings in free text, where one has to use regular expression to extract the needed joined table information out of it. Thanks in advance! David

• How to read directory using jQuery .ajax()?

  - by C.W.Holeman II

  Using jQuery .ajax() to read "./ex.html" returns the expected contents of the file. Using the same call just changing the request to "./" does not return an expected directory listing. <html> <head> </head> <body> <script type="text/JavaScript" src="jquery.js"></script> <script type="text/JavaScript"> alert($.ajax({type: "GET", url: './ex.html', async: false}).responseText); alert($.ajax({type: "GET", url: './', async: false}).responseText); </script> </body> </html>

• Simulated Annealing Applications

  - by Andrei Vajna II

  Do you know any real applications for Simulated Annealing? Simulated Annealing is a heuristic algorithm used for problems like the traveling salesman or the knapsack problem. And yes, this is homework. I have to write a paper on this, and I thought this would be the best starting point. Perhaps someone actually works on a project that relies on Simulated Annealing.

• DataReader already open when using LINQ

  - by Jamie Dixon

  I've got a static class containing a static field which makes reference to a wrapper object of a DataContext. The DataContext is basically generated by Visual Studio when we created a dbml file & contains methods for each of the stored procedures we have in the DB. Our class basically has a bunch of static methods that fire off each of these stored proc methods & then returns an array based on a LINQ query. Example: public static TwoFieldBarData[] GetAgesReportData(string pct) { return DataContext .BreakdownOfUsersByAge(Constants.USER_MEDICAL_PROFILE_KEY, pct) .Select(x => new TwoFieldBarData(x.DisplayName, x.LeftValue, x.RightValue, x.TotalCount)) .ToArray(); } Every now and then, we get the following error: There is already an open DataReader associated with this Command which must be closed firs This is happening intermittently and I'm curious as to what is going on. My guess is that when there's some lag between one method executing and the next one firing, it's locking up the DataContext and throwing the error. Could this be a case for wrapping each of the DataContext LINQ calls in a lock(){} to obtain exclusivity to that type and ensure other requests are queued?
