Swift does not support multiple inheritance. That is, you cannot inherit from more than one class. class Animal { ... } class Pet { ... } class Dog: Animal, Pet { ... } // This will result in a compiler error. Instead you are encouraged to use composition when creating your types. This can b...

UseExceptionHandler can be used to handle exceptions globally. You can get all the details of exception object like Stack Trace, Inner exception and others. And then you can show them on screen. You can easily implement like this. app.UseExceptionHandler( options => { options.Run( as...

Higher-order functions take other functions as arguments and/or return them as results. They form the building blocks of functional programming. Most functional languages have some form of filter function, for example. This is a higher-order function, taking a list and a predicate (function that ret...

Overview Openssl consists of 2 libraries: libcrypto and libssl. Before openssl API can be used in an application, mandatory initialization procedures are expected to be performed. Once application is done with openssl related work, it is expected to cleanup allocated resources. Code below does com...

Depending on which LocationStrategy is used, Location will either persist to the URL's path or the URL's hash segment. Location is responsible for normalizing the URL against the application's base href. import {Comp...

Given data Empty a we have data Free Empty a = Pure a -- the Free constructor is impossible! which is isomorphic to data Identity a = Identity a

Given data Identity a = Identity a we have data Free Identity a = Pure a | Free (Identity (Free Identity a)) which is isomorphic to data Deferred a = Now a | Later (Deferred a) or equivalently (if you promise to evaluate the fst element first) (Nat, a), aka Writer...

Given data Identity a = Identity a we have data Cofree Identity a = a :< Identity (Cofree Identity a) which is isomorphic to data Stream a = Stream a (Stream a)

Debugging takes time and effort. Instead of chasing bugs with a debugger, consider spending more time on making your code better by: Write and run Tests. Python and Django have great builtin testing frameworks - that can be used to test your code much faster than manually with a debugger. Writ...

If you want to investigate why you are maxing out your DTUs, add other metrics to the performance graph to see which metric is dominiationg your DTU usage. In this example, the DTU usage is clearly dominiated by the CPU usage
