Why can't C++ be parsed with a LR(1) parser?
...
I'm quite puzzled by the citation extracted from a PhD Thesis. If there is an ambiguïty, then, by definition, NO lookahead may ever "resolve" the ambiguity (i.e. decide which parse is the correct oen, as at least 2 parses are considered correct by the gramma...
Why no love for SQL? [closed]
...mbiguous, and also because most vendors have added their own (nonstandard) extras there. That is, SQL written for a MySQL DB might not work quite similarly with, say, an Oracle DB — even if it "should".
I agree, though, that SQL is way better than most of the abstraction layers out there. It's no...
How do I check if a type is a subtype OR the type of an object?
...nly correct answer to your question (as I see it) is that you will need an extra check:
typeof(Derived).IsSubclassOf(typeof(Base)) || typeof(Derived) == typeof(Base);
which of course makes more sense in a method:
public bool IsSameOrSubclass(Type potentialBase, Type potentialDescendant)
{

What is Gradle in Android Studio?
...g with Visual Studio by comparison is awesome (or even X-Code) - no crappy extras needed. The IDE builds the project and solution without the need to tinker around in random files for settings that the Android build process needs at times or through updates of old projects. Gradle is the worst par...

How do the Proxy, Decorator, Adapter, and Bridge Patterns differ?
... but also abstraction. It adds one more indirection to the delegation. The extra delegation is the bridge. It decouples Adapter even from adapting interface. It increases complexity more than any other of the other wrapping patterns, so apply with care.

What is the purpose of python's inner classes?
... methods of the outer class — they will see the outer's self without any extra work required (just use a different identifier where you would typically put the inner's self; like innerself), and will be able to access the outer instance via that.

C/C++ with GCC: Statically add resource files to executable/library
...This works, because a) Most executable image formats don't care if there's extra data behind the image and b) zip stores the file signature at the end of the zip file. This means, your executable is a regular zip file after this (except for your upfront executable, which zip can handle), which can b...
Difference between framework and static library in xcode4, and how to call them
...c libraries instead.
Static libraries are fine, but they require a bit of extra work on the part of the user. You need to link your project to the library and you need to copy the header files into your project or reference them somewhere by setting the appropriate header search paths in your build...
