The content mode property of a view tells how its content should be laid out. In the Interface Builder, the various modes can be selected in the Attributes Inspector. Let's use two image views to see how the various modes work. Scale to Fill The image heights and widths are stretched to mat...

The return method only returns from the lambda, not the outer method. Beware that this is different from Scala and Kotlin! void threeTimes(IntConsumer r) { for (int i = 0; i < 3; i++) { r.accept(i); } } void demo() { threeTimes(i -> { System.out.println(i); return...

The package mmand provides functions for the calculation of Mathematical Morphologies for n-dimensional arrays. With a little workaround, these can also be calculated for raster images. library(raster) library(mmand) r <- raster("C:/Program Files/R/R-3.2.3/doc/html/logo.jpg") plot...

The following uses a variable with a for loop to rename a group of files. SetLocal EnableDelayedExpansion for %%j in (*.*) do ( set filename=%%~nj set filename=!filename:old=new! set filename=Prefix !filename! set filename=!filename! Suffix ren "%%j" "!filename!%%~x...

$ git show # equivalent to 'git show HEAD' 'HEAD' names the commit on which you based the changes in the working tree, and is usually the symbolic name for the current branch. Many (but not all) commands that take revision parameter defaults to 'HEAD' if it is missing.

Drag a gesture recognizer from the object library onto your view. Control drag from the gesture in the Document Outline to your View Controller code in order to make an Outlet and an Action. Notes This example comes from this fuller sample project demonstrating gesture recognizers.

To print the value of a pointer to an object (as opposed to a function pointer) use the p conversion specifier. It is defined to print void-pointers only, so to print out the value of a non void-pointer it needs to be explicitly converted ("casted*") to void*. #include <stdlib.h> /*...

Sometimes we need to fetch and print the value of a TensorFlow variable to guarantee our program is correct. For example, if we have the following program: import tensorflow as tf import numpy as np a = tf.Variable(tf.random_normal([2,3])) # declare a tensorflow variable b = tf.random_normal([2...

An SKView does not need to fill the whole screen and can share space with other UI controls. You can even have more than one SKView displayed at once if you wish. To create a smaller SKView amongst other controls with Interface Builder, first create a normal ViewController, then drag and drop a new...

In order to print the value of a variable such as, set tempVar "This is a string." The argument in the puts statement is preceded by a $ sign, which tells Tcl to use the value of the variable. % set tempVar "This is a string." This is a string. % puts $tempVar This is a s...

Subtracting the values of two pointers to an object results in a signed integer *1. So it would be printed using at least the d conversion specifier. To make sure there is a type being wide enough to hold such a "pointer-difference", since C99 <stddef.h> defines the type ptrdiff_t. ...

It is generally not considered 'best practice' to re-purpose the reserved names of Properties or Methods as the name(s) of your own procedures and variables. Bad Form - While the following is (strictly speaking) legal, working code the re-purposing of the Find method as well as the Row, Column and ...

survival is the most commonly used package for survival analysis in R. Using the built-in lung dataset we can get started with Survival Analysis by fitting a regression model with the survreg() function, creating a curve with survfit(), and plotting predicted survival curves by calling the predict m...

:set foldmethod={method} sets the fold method for the current window. This determines how folds are manipulated within that window. Valid options for "method" are: manual (folds are manually created and destroyed by the user) indent (folds are created for lines of equal indentation) m...

zv will ensure the line containing the cursor is not folded. The minimum number of folds required to expose the cursor line will be opened.
