Suppose the following matrix is the transition probability matrix associated with a Markov chain. 0.5 0.2 0.3 P= 0.0 0.1 0.9 0.0 0.0 1.0 In order to study the nature of the states of a Markov chain, a state transition diagram of the Markov chain is drawn. \documentclass[12pt...

Linux/Unix Once you have Progress installed it's very easy to run. You only need a couple of environment variables. The directory where Progress was installed (default /usr/dlc but can be something else) needs to be in the DLC-variable DLC=/usr/dlc And you might also want the "bin" s...

When moving to "Running" state there is special handler connected with this event: Open "App.xaml.cx" class and see "OnLaunched" method - this is activated when applicaiton is opened by user from "Terminaded" state: protected override void OnLaunched(LaunchA...
When moving to "Suspened" state there is special handler connected with this event: Open "App.xaml.cx" class and see "App" constructor - there is event handler: public App() { this.InitializeComponent(); //Handle suspending operation with event h...
Your application can be opened by user from "Suspended" state. When doing it "OnResuming" event handler is used. In "App.xaml.cs" class: public App() { this.InitializeComponent(); this.Suspending += OnSuspending; //Handle resuming operat...

In the official reference document, it says: The main function of an inbound Channel Adapter is to execute a SQL SELECT query and turn the result set as a message. The message payload is the whole result set, expressed as a List, and the types of the items in the list depend on the row-mapping st...
In the Spring Integration Reference Docuement, it says: The outbound Channel Adapter is the inverse of the inbound: its role is to handle a message and use it to execute a SQL query. The message payload and headers are available by default as input parameters to the query... Java code p...
As you can see the layout of this gem is very catching and user friendly.

In order to achieve type safety sometimes we want to avoid the use of primitive types on our domain. For instance, imagine a Person with a name. Typically, we would encode the name as a String. However, it would not be hard to mix a String representing a Person's name with a String representing an e...

In OCaml, there are different arithmetic operators for floats and integers. Additionally, these operators can only be used on 2 floats or 2 integers. Here are invalid expressions in OCaml 1.0 + 2.0 1 + 2.0 1 +. 2 1 +. 2.0 The correct expression for each of these respectively are 1. +. 2. fl...
This is just an extension on the sealed trait variant where a macro generates a set with all instances at compile time. This nicely omits the drawback that a developer can add a value to the enumeration but forget to add it to the allElements set. This variant especially becomes handy for large en...
