How can I cast int to enum?
.... If you ask how to get to that level, I'd suggest building a ton of small test cases, making them tougher as you go, try to predict the outcome every time, and test them afterwards (incl. decompilation, etc). After figuring out all the details and all the characteristics, you can check if you got i...
What are bitwise operators?
...p; 4 is a bitwise AND, so it will return 0.
You can copy the following to test.html or something and test:
<html>
<body>
<script>
alert("\"Cat\" && \"Dog\" = " + ("Cat" && "Dog") + "\n"
+ "2 && 4 = " + (2 && 4) + "\n"
+ "2 &...
How do you get the list of targets in a makefile?
... database
-Rr suppresses inclusion of built-in rules and variables
-q only tests the up-to-date-status of a target (without remaking anything), but that by itself doesn't prevent execution of recipe commands in all cases; hence:
-f $(lastword $(MAKEFILE_LIST)) ensures that the same makefile is targe...

exec sp_updatestats
If that doesn't work you could also try
dbcc freeproccache
You should not do this when your server is under heavy load because it will temporarily incur a big performace hit as all stored procs and queries are re...

How to write a scalable Tcp/Ip based server
...don't know why this is the highest voted answer. Begin* End* is not the fastest way of doing networking in C#, nor the most highly scalable. It IS faster than synchronous, but there are a lot of operations that go on under the hood in Windows that really slow down this network path.

Best practice for partial updates in a RESTful service
...I couldn't find in the list of valid HTTP verbs so that would require more testing. How would I construct an URI if I want the system to send an email to customer 123? Something like a pure RPC method call that doesn't change the state of the object at all. What is the RESTful way of doing this?

Why C# implements methods as non-virtual by default?
... the effort needed for good overall design (good content, clear use cases, testing, documentation), designing for inheritance really isn't too bad. And if you're not publishing, virtual-by-default is less time-consuming, and you can always fix the small portion of cases where it's problematic.

Can You Get A Users Local LAN IP Address Via JavaScript?
... function that they found. This will either return false or an array. When testing remember that you need to collapse the array in the web developer console otherwise it's nonintuitive default behavior may deceive you in to thinking that it is returning an empty array.
