Java SE 1.2 strictfp modifier is used for floating-point calculations. This modifier makes floating point variable more consistent across multiple platforms and ensure all the floating point calculations are done according to IEEE 754 standards to avoid errors of calculation (round-off errors), ov...

This worked for me to move from Ubuntu 12.04 (Jenkins ver. 1.628) to Ubuntu 16.04 (Jenkins ver. 1.651.2). I first installed Jenkins from the repositories. Stop both Jenkins servers Copy JENKINS_HOME (e.g. /var/lib/jenkins) from the old server to the new one. From a console in the new serve...

Create a new project.json and example Program.cs: dotnet new Restore needed packages: dotnet restore Compile and run the example: dotnet run

Go to the project.json directory and publish: dotnet publish It will print the output directory of the operation, enter the directory and run the published project: dotnet <project output>.dll The default folder will be: <project root>/bin/<configuration>/<target framewo...

Simple example Assuming that the "HelloWorld.java" contains the following Java source: public class HelloWorld { public static void main(String[] args) { System.out.println("Hello world!"); } } (For an explanation of the above code, please refer to Gettin...

Standard You don't need to create the variable, but it's a good practice as you can use that variable with clearInterval to stop the currently running interval. var int = setInterval("doSomething()", 5000 ); /* 5 seconds */ var int = setInterval(doSomething, 5000 ); /* same thing, no qu...

If the program is short, you can include it in the command that runs awk: awk -F: '{print $1, $2}' /etc/passwd In this example, using command line switch -F: we advise awk to use : as input fields delimiter. Is is the same like awk 'BEGIN{FS=":"}{print $1,$2}' file Alternativelly, ...

Prolog tries alternative clauses for a predicate in the order of appearance: likes(alice, music). likes(bob, hiking). // Either alice likes music, or bob likes hiking will succeed. The disjunction (OR) operator ; can be used to express this in one rule: likes(P,Q) :- ( P = alice , Q = ...

Conjunction (logical AND) is represented by the comma , operator (among other roles). Conjunction between clauses can appear in a query: ?- X = 1, Y = 2. Conjunction can also appear between the subgoal clauses in the body of a rule: triangleSides(X,Y,Z) :- X + Y > Z, X + Z > Y, Y + ...

Sometimes it is desirable to prevent Prolog from backtracking into alternative solutions. The basic tool available to the programmer to stop prolog from continuing futher in its backtrack is the cut operator. consider the following. % (percent signs mean comments) % a is the parent of b, c, and d....

ValueAnimator introduces a simple way to animate a value (of a particular type, e.g. int, float, etc.). The usual way of using it is: Create a ValueAnimator that will animate a value from min to max Add an UpdateListener in which you will use the calculated animated value (which you can obtain ...

ObjectAnimator is a subclass of ValueAnimator with the added ability to set the calculated value to the property of a target View. Just like in the ValueAnimator, there are two ways you can create the ObjectAnimator: (the example code animates an alpha of a View from 0.4f to 0.2f in 250ms) Fr...

ViewPropertyAnimator is a simplified and optimized way to animate properties of a View. Every single View has a ViewPropertyAnimator object available through the animate() method. You can use that to animate multiple properties at once with a simple call. Every single method of a ViewPropertyAnimat...

Official page: https://www.rebar3.org/ Source code: https://github.com/erlang/rebar3 Rebar3 is mainly a dependency manager for Erlang and Elixir projects, but it also offers several other features, like bootstrapping projects (according to several templates, following the OTP principles), task exe...

Rebar3 is written in Erlang, so you need Erlang to run it. It is available as a binary that you can download and run. Just fetch the nightly build and give it execution permissions: $ wget https://s3.amazonaws.com/rebar3/rebar3 && chmod +x rebar3 Place this binary in a convenient place a...

As Rebar3 is free, open source and written in Erlang, it's possible to simply clone and build it from the source code. $ git clone https://github.com/erlang/rebar3.git $ cd rebar3 $ ./bootstrap This will create the rebar3 script, which you can put on your PATH or link to /usr/local/bin as expl...

To bootstrap a new Erlang project, simply choose the template you want to use from the list. The available templates can be retrieved by the following command: $ rebar3 new app (built-in): Complete OTP Application structure cmake (built-in): Standalone Makefile for building C/C++ in c_src escr...

We can always use ListView or RecyclerView for selection from list of items, but if we have small amount of choices and among those choices we want user to select one, we can use AlertDialog.Builder setAdapter. private void showDialog() { AlertDialog.Builder builder = new AlertDia...

Sectioning is a concise way to partially apply arguments to infix operators. For example, if we want to write a function which adds "ing" to the end of a word we can use a section to succinctly define a function. > (++ "ing") "laugh" "laughing" Notice...

Hash tables are created by make-hash-table: (defvar *my-table* (make-hash-table)) The function may take keyword parameters to further specify the behavior of the resulting hash table: test: Selects the function used to compare keys for equality. Maybe a designator for one of the functions eq,...
