Get the generated SQL statement from a SqlCommand object?
...n improvements :)
This does an OK job on data types and output parameters etc similar to using "execute stored procedure" in SSMS. We mostly used SPs so the "text" command doesn't account for parameters etc

What is the difference between C# and .NET?
...must be defined and rules governing them e.g. inheritance, object lifetime etc. C++/CLI, C#, VB are all languages conforming to these types (you could in violate this but I wont get into it). .Regardless of what language you use to construct the type, behavior will be same when executed by .NET CLR....
SPA best practices for authentication and session management
...ilding SPA style applications using frameworks like Angular, Ember, React, etc. what do people believe to be some best practices for authentication and session management? I can think of a couple of ways of considering approaching the problem.

...
This is what we use in ASP.NET:
// Stop Caching in IE
Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
// Stop Caching in Firefox

Threading in a PyQt application: Use Qt threads or Python threads?
...ds are better
integrated with Qt (asynchrnous signals/slots, event loop, etc.).
Also, you can't use Qt from a Python thread (you can't for instance
post event to the main thread through QApplication.postEvent): you
need a QThread for that to work.
A general rule of thumb might be to use...
log4j logging hierarchy order
...ation is also vague on this. The output method such as error, info, debug, etc. of the logger assigns a priority/severity level to the logging message. If the logging really takes effect (the message will be visible) depends on the effective logging level of the logger being used.

Google Guice vs. PicoContainer for Dependency Injection
...work in your code. Because they do have a lot of other helpers / utilities etc. the temptation is pretty strong to depend on Spring code, though.
