  How to read Haskell like Python

Have you ever been in the situation where you need to quickly understand what a piece of code in some unfamiliar language does? If the language looks a lot like what you’re comfortable with, you can usually guess what large amounts of the code does; even if you may not be completely familiar how all the language features work.For Haskell, this is a little more difficult, since Haskell syntax looks very different from traditional languages. But there's no really deep difference here; you j...

  Kubernetes Authentication & Authorization 101

If we want to build a system with user modules, Authentication and Authorization are something that we can never ignore, though they could be fuzzy to understand.

  Functional Programming in C++

Probably everyone reading this has heard “functional programming” put forth as something that is supposed to bring benefits to software development, or even heard it touted as a silver bullet.  However, a trip to Wikipedia for some more information can be initially off-putting, with early references to lambda calculus and formal systems.  It isn’t immediately clear what that has to do with writing better software. My pragmatic summary:  A large fraction of th...

  JavaScript efficiency catch up

JavaScript is a very flexible language, we can write JavaScript code freely with various styles, different kinds of codes will have different execution efficiency. Here we summarize some tips we get from our development. Efficiency of JavaScript itself JavaScript has execution context chain, closures, prototype inheritance, eval etc. It brings us some magic features, but it also introduces the performance issue, if we don't use them properly, it will affect the codes execution efficiency. 1. Glo...

  All Programming is Web Programming

Michael Braude decries the popularity of web programming:The reason most people want to program for the web is that they're not smart enough to do anything else. They don't understand compilers, concurrency, 3D or class inheritance. They haven't got a clue why I'd use an interface or an abstract class. They don't understand: virtual methods, pointers, references, garbage collection, finalizers, pass-by-reference vs. pass-by-value, virtual C++ destructors, or the differences between C# struc...

  Communicating Between Widgets in a Rich Internet Application

As a part of our October Free Dojo Support initiative, we received the following question from Manu Subramanian about how to manage communication between distinct components in a rich internet application: We are building an application with dojo. It does have many inter connected interface parts. For example it does have a top bar with drop down buttons. The menu items opens tabs in a tab controller. In general we need to call functions from different widgets or there are many interconne...
