Four Habit-Forming Tips to Faster C++
Are you a victim of premature pessimisation? Here’s a short definition from Herb Sutter: Premature pessimization is when you write code that is slower than it needs to be, usually by asking for unnecessary extra work, when equivalently complex code would be faster and should just naturally flow out of your fingers. Despite how amazing today’s […]

Qt on Android: How to restart your application
Some time ago, I wrote a code to restart the running application on Android. You might well ask why such a thing was needed. It was needed because there are cases where, whenever a user changes the theme, the application has to restart to apply the change (it can’t be applied on the fly). In […]

Very explicit operator bool Is the Safe Bool Idiom still useful in C++11 / C++14?
From time to time I scroll through Qt-related forums and mailing lists, and whenever possible I try to help fellow developers out. The other day a StackOverflow thread caught my attention: a developer was asking “What is the purpose of operator RestrictedBool in QScopedPointer?” Indeed, looking at QScopedPointer‘s implementation, one notices the strange RestrictedBool usage. […]
Faster than Fast String Search in Qt
Is your code burning a lot of cycles hunting for strings? Maybe you need to find the proper charset nestled in a chunk of HTML, or look for the dimensions in an XPM image file, or locate the email attachment boundaries in a block of MIME. If you string search a lot and performance is […]
