You can only place <h2> elements within <a> elements if you’re working with HTML5, which allows any other elements within <a> elements. Previous specifications (or current ones however you want to look at them) never allowed this. The usual way of doing this is to place <a> within <h2>. This works, has always worked, and … Read more
PSR-2 and PSR-12 (by PHP Framework Interoperability Group) do not mention short array syntax. But as you can see in chapter 4.3 they use short array syntax to set the default value of $arg3 to be an empty array. So for PHP >= 5.4 the short array syntax seems to be the de-facto standard. Only … Read more
nav is used for groups of internal links (a elements). Generally this means the links should travel to separate pages, or change content in the case of an AJAX page. Expect some sort of content change when clicking on a nav item. menu is used for groups of controls (a, input, button). Generally this means … Read more
If you are trying to get a Root Cause issue using blame, don’t forget use the -w flag to ignore all the white-spaces or indentation changes. So you’ll get the last real change to the code, instead just an indentation, or removing trailing spaces. git blame -w app/to/file.rb or you can just use, git slap … Read more
In order to provide the amortized constant time complexity required by range, filter_view::begin caches the result in *this. This modifies the internal state of *this and thus cannot be done in a const member function.
The C++ standard headers do not have a “.h” suffix. I believe the reason is that there were many, different pre-standard implementations that the standard would break. So instead of requiring that vendors change their exiting “iostream.h” (for example) header to be standards compliant (which would break their existing user’s code), the standards committee decided … Read more

The semantics for op== and op!= explicitly say that the mapping is except for their truth-value result. So you need to look what is defined for their truth value result. If they say that the result is unspecified, then it is unspecified. If they define specific rules, then it is not. It says in particular … Read more
Historical reasons, mostly. Expressions of type char are promoted to int in most contexts (because a lot of CPUs don’t have 8-bit arithmetic operations). On some systems, sign extension is the most efficient way to do this, which argues for making plain char signed. On the other hand, the EBCDIC character set has basic characters … Read more
I refer to the C++11 standard in this post Declarations Declarations of the type we’re concerned with are known as simple-declarations in the grammar of C++, which are of one of the following two forms (ยง7/1): decl-specifier-seqopt init-declarator-listopt ; attribute-specifier-seq decl-specifier-seqopt init-declarator-list ; The attribute-specifier-seq is a sequence of attributes ([[something]]) and/or alignment specifiers (alignas(something)). … Read more
