This is possible with lombok 1.18.2 (and above) using the new (experimental) annotation @SuperBuilder. The only restriction is that every class in the hierarchy must have the @SuperBuilder annotation. There is no way around putting @SuperBuilder on all subclasses, because Lombok cannot know all subclasses at compile time. See the lombok documentation for details. Example: … Read more
C++-specific ones: RAII and PIMPL.
Suppose you create a View class that displays your items in a certain way. Now you decide you also want a version of it which is scrollable, so you create a ScrollableView which inherits the View. Later you decide you also want a version with a border so you now need to make a BorderedView … Read more
I wholeheartedly agree with the YAGNI principle, but you still want to plan for success. If an application needs a complete rewrite when it suddenly has more than ten users, then it’s YAGNI taken too far. Some things You Are Gonna Need. From my perspective, the two most important points: Don’t shoot yourself in the … Read more
The code is older than that – I wrote it some time before .NET 2.0 came out. The concept of a producer/consumer queue is way older than that though 🙂 Yes, that code is safe as far as I’m aware – but it has some deficiencies: It’s non-generic. A modern version would certainly be generic. … Read more

There are lots of oxygen molecules, but only one canonical oxygen element.) The concept of True The concept of False You could instantiate lots of True objects, but they will all refer to … Read more
Doc was developed using the InterViews UI toolkit. I believe that doc source is part of the InterViews distribution. Doc was used to typeset Paul’s thesis. (Paul Calder was my lecturer at Flinders University) If you look at the InterViews code you might be surprised. It was developed before modern C++ existed. For example, there … Read more
Okay as far as I can tell you are asking three different questions: Where are they complementary to each other? (e.g. what does https://github.com/lvbreda/Meteor_angularjs bring to the table) AngularJS is a full stack client side framework that brings ton’s of features for frontend development. The following things it brings to the table above standard meteor: … Read more
Because every organization has different needs, you should adapt your design while designing and building a dynamic and flexible user management system. Role Based Access Control (RBAC) is a common approach. In this model, users are assigned roles, and the roles have corresponding permissions. As a result, instead of granting permissions directly to users, permissions … Read more
This becomes useful if I have a set of classes that I want a default implementation of test() for (so they can extend from Foo), and a subset of those classes that I want to force to provide their own implementation (in which case making it abstract in the subclass would enforce this.) Of course, … Read more
