Prerequisites JDK 1.7 or later installed. You can find the Oracle JDK's here. Steps Download Payara Server Full. Unzip the Payara Server at some location on your computer. We will use C:\payara41 as INSTALL_DIR for Windows users and /payara41 for Linux/Mac users. Starting / stopping Pa...

Using the Profiler Class One very good practice is to use Profiler.BeginSample and Profiler.EndSample because it will have its own entry in the Profiler Window. Also, those tag will be stripped out on non-Development build using using ConditionalAttribute, so you don't need to remove them from you...

If you want to sort your data numerically or alphabetically, you can simply use order by [column]. If you want to sort using a custom hierarchy, use a case statement. Group ----- Total Young MiddleAge Old Male Female Using a basic order by: Select * from MyTable Order by Group retur...

Assuming you have a handle on the Hibernate Session object, in this case named session: List<Object[]> result = session.createNativeQuery("SELECT * FROM some_table").list(); for (Object[] row : result) { for (Object col : row) { System.out.print(col); } } Thi...

You could migrate from team foundation version control to git by using an open source tool called Git-TF. Migration will also transfer your existing history by converting tfs checkins to git commits. To put your solution into Git by using Git-TF follow these steps: Download Git-TF You can downloa...

This is contrived; but some COBOL programmers may prefer the positive clarity, versus using NOT in conditional expressions (especially with the logic error prone var NOT = value OR other-value). if action-flag = "C" or "R" or "U" or "D" continue else...

(The following is a simplified version of what the Java Language Specification says. For a deeper understanding, you need to read the specification itself.) Happens-before relationships are the part of the Memory Model that allow us to understand and reason about memory visibility. As the JLS say...

To query a field which name is contained in a variable, use the field function. some_field = :id some_value = 10 from p in Post, where: field(p, ^some_field) == ^some_value

To join and and for instance filter on the joined table use JoinQueryOver. IList<Customer> customers = session.QueryOver<Customer>() .Inner.JoinQueryOver(x => x.Organisation) .Where(y => y.Name == "Acme Inc") .List();

For interacting with plots Matplotlib offers GUI neutral widgets. Widgets require a matplotlib.axes.Axes object. Here's a slider widget demo that ùpdates the amplitude of a sine curve. The update function is triggered by the slider's on_changed() event. import numpy as np import matplotlib.pyplot...

If you are new to middleware in Express check out the Overview in the Remarks section. First, we are going to setup a simple Hello World app that will be referenced and added to during the examples. var express = require('express'); var app = express(); app.get('/', function(req, res) { r...

A good VOD (Video On Demand) service should start with the basics. Lets say you have a directory on your server that is not publicly accessible, yet through some sort of portal or paywall you want to allow users to access your media. var movie = path.resolve('./public/' + req.params.filename); ...

This example uses the map format introduced in Erlang/OTP 18.0. %% A module implementing a supervisor usually has a name ending with `_sup`. -module(my_sup). -behaviour(supervisor). %% API exports -export([start_link/0]). %% Behaviour exports -export([init/1]). start_link() -> ...

We initialize the data: [X,Y] = meshgrid(1:2:10); Z = X.*cos(Y) - Y.*sin(X); The surface looks like the following. Now we set the points where we want to interpolate: [Vx,Vy] = meshgrid(1:0.25:10); We now can perform nearest interpolation, Vz = interp2(X,Y,Z,Vx,Vy,'nearest'); line...

We will use the following data: x = 1:5:50; y = randi([-10 10],1,10); Hereby x and y are the coordinates of the data points and z are the points we need information about. z = 0:0.25:50; One way to find the y-values of z is piecewise linear interpolation. z_y = interp1(x,y,z,'linear'); ...

One implementation of the io.Reader interface can be found in the bytes package. It allows a byte slice to be used as the source for a Reader. In this example the byte slice is taken from a string, but is more likely to have been read from a file or network connection. message := []byte("Hello...

Send a Razor part to a @helper, for example a HTML div. @helper WrapInBox(Func<Object, HelperResult> content) { <div class="box">@content(null) </div> } //call @WrapInBox(@<div> I'm a inner div </div>)
