I have a client/server application that communicates with .Net remoting. I need my clients to be able to find the server(s) on the network without requiring client-side configuration.

UDP [multicast](http://en.wikipedia.org/wiki/Multicast) solution. Basically, multicast is very similar to a broadcast, but only machines that have joined the multicast group (i.e. requested the broadcast) are contacted.

In PHP5 you'd write a user object which will carry its own data and methods for authentication. Your code will be clearer and easier to maintain as everything having to do with users and authentication will be concentrated in a single place. | [

In Ruby 1.8 and earlier,
```
Foo

is a constant (a Class, a Module, or another constant). Whereas
```
foo

is a variable. The key difference is as follows:
```
module Foo
bar = 7
BAZ = 8
end
Foo::BAZ

Foo::bar

This isn't a way to page the data, but have you looked into the [ListView](http://msdn.microsoft.com/en-us/library/bb398790.aspx) control? It gives the flexibility of repeater / data list but with built in paging like the grid view.
And for paging in sql, you ... | [

As a novice developer who is getting into the rhythm of my first professional project, I'm trying to develop good habits as soon as possible. However, I've found that I often forget to test, put it off, or do a whole bunch of tests at the end of a build instead of one at a time.
My question is what rhythm do you like ... | [

I want to get more into testing, but I am currently in a position where we are working to "get the code out" rather than "get the code out right" which scares the crap out of me. So I am slowly trying to integrate testing processes in my development cycle.
Currently, **I test as I code, trying to bust the code as I wr... | [

what my "vision" for the class is.

become the unit tests.

8. If any new bugs come to light following this, I then go back and write the new test in, make sure it fails (this also serves as proof-of-concept for the bug) then fix it..
I hope that helps.. Open to comments on how to improve this, as I said it is a concern of mine.. | [

What's the best way to handle a user going back to a page that had cached items in an asp.net app? Is there a good way to capture the back button (event?) and handle the cache that way?
