• Custom Content-Type for File in Rails 'public' Folder

  - by Kevin Sylvestre

  For assets stored in the 'public' folder of a ruby-on-rails application is it possible to change the 'Content-Type' when running 'script/server'? For example, I am attempting to create an HTML5 application supporting offline mode, and have an 'offline.manifest'. When I run: curl -I localhost:3000/offline.mainfest The following header information is returned: HTTP/1.1 200 OK ... Content-Type: text/plain ... However, HTML5 specifications require: HTTP/1.1 200 OK ... Content-Type: text/cache-manifest ...

• ConcurrenctBag(Of MyType) Vs List(Of MyType)

  - by Ben

  What is the advantage of using a ConcurrentBag(Of MyType) against just using a List(Of MyType)? The MSDN page on the CB (http://msdn.microsoft.com/en-us/library/dd381779(v=VS.100).aspx) states that ConcurrentBag(Of T) is a thread-safe bag implementation, optimized for scenarios where the same thread will be both producing and consuming data stored in the bag So what is the advantage? I can understand the advantage of the other collection types in the Concurrency namespace, but this one puzzled me. Thanks.

• 100k+ Records and sp_xml_preparedocument

  - by Jonn

  I've been encountering a seeming deadlock with one of my tables and the only place I can trace it back to is a stored procedure that uses sp_xml_preparedocument on a list of data. The data inserted, btw, consists of a 100k+ records on average. Is it possible that it is causing the deadlock? What other pitfalls does using sp_xml_preparedocument have?

• What should be the RegEx if I want to find the text between the phrases " IF (NEW." and " !"?

  - by Parth

  What should be the RegEx if I want to find the text between the phrases " IF (NEW." and " !"? Likewise I am thinking of the pattern as $pattern = '/(?<= IF (NEW.)[^ !]+/'; I am matching it as $input = $row4['ACTION_STATEMENT']; preg_match_all($pattern, $input, $captures); What if I want $captures as an array, in which all values will be stored which will match with above pattern being in between of this pattern?

• ASP.NET 'Session.Remove(key)' v/s 'Session(key) = nothing'

  - by Whiskey-Tango-Foxtrot

  I've seen developers use two approaches when they are done with a session object. 1) Session.Remove(key) 2) Session(key) = nothing What is the better approach of the two above? Does Session.Remove dispose the object stored automatically? Does the second approach depend on the garbage collector to actually free up the memory? Thanks.

• How to store the hostname in a variable in a .bat file?

  - by eqbridges

  I would like to convert this /bin/sh syntax into a widely compatible Windows batch script: host=`hostname` echo ${host} How to do this so that it'll work on any Windows Vista, Windows XP, and Windows 2000 machine? To clarify: I would then like to go on in the program and use the hostname as stored in the variable host. In other words, the larger goal of the program is not to simply echo the hostname.

• Am I supposed to store hashes for passwords?

  - by Doug

  User System and Passwords: I was looking through MD5 stuff, and I am wondering what is the normal/good practice for passwords. Right now, I think people super encrypt the passwords and store the hashes. If so, how does password checking work? I just have the input password go through the encryption process again and then check the hash with the stored one, correct? This question may contradict the above, but should my salt ever be a randomly generated value?

• C#. Where struct methods code kept in memory?

  - by maxima120

  It is somewhat known where .NET keeps value types in memory (mostly in stack but could be in heap in certain circumstances etc)... My question is - where is the code of the struct? If I have say 16 byte of data fields in the struct and a massive computation method in it - I am presuming that 16 byte will be copied in stack and the method code is stored somewhere else and is shared for all instances of the struct. Are these presumptions correct?
