Here’s some pretty basic reasons. (1) If a query (insert, update, delete) violates a constraint, SQL will generate an error message that will contain the constraint name. If the constraint name is clear and descriptive, the error message will be easier to understand; if the constraint name is a random guid-based name, it’s a lot … Read more
This behavior is unfortunate and doesn’t even appear to be documented. .htaccess per-dir context Here’s what appears to happen in .htaccess per-directory (per-dir) context: Assume that Apache processes an .htaccess file that includes rewrite directives. Apache populates its environment variable map with all of the standard CGI / Apache variables Rewriting begins Environment variables are … Read more
Historically, the first extensions used for C++ were .c and .h, exactly like for C. This caused practical problems, especially the .c which didn’t allow build systems to easily differentiate C++ and C files. Unix, on which C++ has been developed, has case sensitive file systems. So some used .C for C++ files. Other used … Read more

I think the truth is ambiguous even from Microsoft documentation: In Visual Studio 2012 and the .NET Framework 4.5, any method that is attributed with the async keyword (Async in Visual Basic) is considered an asynchronous method, and the C# and Visual Basic compilers perform the necessary transformations to implement the method asynchronously by using … Read more
This is a valid question. Such a thing is possible in other languages. In C#, prefix the identifier with @ (as asked before); in Delphi, prefix with &. But Java offers no such feature (partly because it doesn’t really need to interact with identifiers defined by other languages the way the .Net world does).
Revision Control is the more generic term, used for source-control tools but also for other tools (Word, OpenOffice, …). It references a version. Source Control offers revision control with branching and merging which are not always available in all revision tools (Word is not a Source Control, but offer revision control features) Version Control is … Read more
The term ‘slug’ comes from the world of newspaper production. It’s an informal name given to a story during the production process. As the story winds its path from the beat reporter (assuming these even exist any more?) through to editor through to the “printing presses”, this is the name it is referenced by, e.g., … Read more
I asked a similar question, but where possible I try to copy the names already in the .NET framework, and I look for ideas in the Java and Android frameworks. It seems Helper, Manager, and Util are the unavoidable nouns you attach for coordinating classes that contain no state and are generally procedural and static. … Read more
No, it is history. GDI+ was written quite a while before .NET ever came around. The SDK wrapper for it was written in C++. Exceptions are iffy in C++, not everybody buys into them. Google doesn’t for example. So to keep it compatible it reports problems with error codes. That just never scales well, library … Read more
