C++ : Ignored qualifiers (-Wignored-qualifiers)

What is an ignored qualifier?  Well, in a class, lets have a student class: #include <string> class Student {     public:         const std::string Name;     private:         bool m_Present;     public:         Student(const std::string& p_Name)             :             Name(p_Name),             m_Present         {         }                 void SetPresent() { m_Present = true; }         void SetAbsent() { m_Present = false; } }; Now, we may want to access the present flag, therefore provide a function to do so:     bool Present() const { return m_Present } This function is telling the user of our class quite a bit, it tells them that the return type is boolean and that the calling...

C++: The Dilemma of using Exceptions

Image
As a C++ developer I've recently been in the midst of the Exceptions debate.  Exceptions as a feature of the C++ language have long divided the community, naively I've often put this down to their coming to the language from elsewhere (C perhaps) where exceptions were not the norm. This was a mistake, for in the projects I've previously worked upon the overhead of an exception compared to the ramifications of the error resulting in a crash have often totally outweighed the overhead, making deciding to employ an exception exceptionally easy (*bum bum*).  Exceptions were the norm, still are and should be to you too (according to the C++ Core Guidelines https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#Ri-except ). The difficulty, the dilemma if you will, comes not from the feature, but the cost.  If you application domain demands high performance you can not risk using exceptions, the argument carries on therefore whether in not using them to avoi...

Virgin Media Cable to Wet String Maybe?

It has been just under a month since I started to measure my internet connection speed, I've been paying for 50Mbit, and receiving pittifully less at all times of the day, and huge dips during what is tabbed the "peak time".  We get massive slow-downs whilst streaming - constantly - opening say ITV player and then opening a web-site for wikipedia totally freezes the player until the whole wikipedia page has loaded - remember wikipedia is mainly text, there's very little media data being exchanged, but the player is just cut off; it's dreadful. There's no reason for this, when I was paying for 200Mbit I was receiving around 33-36MBit at all times, so deciding to pay for only 50Mbit I was to save money and still get this speed I had had - since I never ever got more... But it seems this is totally beyond Virgin Media, they're playing speed throttling shenanigans .... However, the clever chaps at Andrews and Arnold engineering might just have the solution for...
