• Simple caching mechanism in ASP.NET

  - by DotnetDude

  I had asked a question on how to implement real time updates in ASP.NET and received a very explanatory and a helpful answer from "jdk" at: http://stackoverflow.com/questions/2347771/how-to-implement-real-time-updates-in-asp-net I understand that memcached or .net caching application block can be used as the caching layer. Currently, I am looking for a very simple mechanism to implement this and do not have the resources for using memcached or the caching application block. Can someone suggest a solution?

Is it the same as passing data across the process boundary? I'm curious to know more about this abstraction and what it is useful for. EDIT: Good existing coverage of AppDomains in general at http://stackoverflow.com/questions/622516/i-dont-understand-appdomains

• Why did Matz choose to make Strings mutable by default in Ruby?

  - by Seth Tisue

  It's the reverse of this question: http://stackoverflow.com/questions/93091/why-cant-strings-be-mutable-in-java-and-net Was this choice made in Ruby only because operations (appends and such) are efficient on mutable strings, or was there some other reason? (If it's only efficiency, that would seem peculiar, since the design of Ruby seems otherwise to not put a high premium on faciliating efficient implementation.)

• UINavigationController Back Button not visible, but works

  - by cagreen

  I have a scenario where my UINavigationController is missing the back button (left button) but tapping the left button still seems to work. I found a similar problem posted here: http://stackoverflow.com/questions/919832/uinavigationcontrollers-back-button-disappears which was resolved by not setting the title to @"", but that's not my problem. Are there any other scenarios that would cause this behaviour? Thanks.

• tinymce, view only

  - by tom smith

  Hi. Evaluating Tinymce. I've looked at the docs/source/api, and have a question that I thought I'd pose to the stackoverflow group. Has anyone implemented Tinymce, who can tell me it it's possible to setup Tinymce to restrict a user, allowing the user to only "view" a text file, and be able to add additional buttons to the save/cancel row of buttons.. I think it should be, and that I'm missing something subtle.. Thanks -Tom

• JavaScript check if anonymous object has a method

  - by Baddie

  How can I check if an anonymous object that was created as such: var myObj = { prop1: 'no', prop2: function () { return false; } } does indeed have a prop2 defined? prop2 will always be defined as a function, but for some objects it is not required and will not be defined.
