• Serializing data from a RSS feed in ASP.NET

  - by DotnetDude

  I'd like the user to specify a RSS feed address and serialize the information from it. I am not interested in the XML format, but populate a strongly typed object from the XML. My question is, is there a standard that all RSS feeds support (Do all of them have date, title etc)? If so, is there a XSD that describes this. If not, how do I handle serializing a RSS feed to an object in ASP.NET?

• Should the function or the caller be resonsible for input validation?

  - by haudenschilt

  I'm doing a security audit on a fairly large php application and was wondering where I should include my user-input validation. Should I validate the data, then send the clean data off to the back-end functions or should I rely on each function to do it's own validation? Or even both? Is there any standard or best-practice for this sort of thing? Currently the app does both inconsistently and I'll like to make things more consistent.

• Package website from Aptana Studio 3

  - by user3699921

  I have a web application built using Aptana Studio 3, the web application is targeted towards different platforms that execute HTML5 applications as native applications therefore not browsers per-se and therefore needs to be build differently for each platform as it is not a standard website. I need to be able to: Specify html templates that can be included/excluded in different builds for the same file Package the website in a zip Optionally override some modules (requirejs is used for modules) as they are device specific Publish to an FTP server Whilst I can do all of this manually it can be error prone.

• echo that outputs to stderr

  - by BCS

  Is there a standard bash tool that acts like echo but outputs to stderr rather than stdout? I know I can do echo foo 1>&2 but it's kinda ugly and, I suspect, error prone (e.g. more likely to get edited wrong when things change).

  In the following code, when the ctor of X is called will the ctor of A or B be called first? Does the order in which they are placed in the body of the class control this?
