The #Const directive is used to define a custom preprocessor constant. These can later be used by #If to control which blocks of code get compiled and executed. #Const DEBUGMODE = 1 #If DEBUGMODE Then Const filepath As String = "C:\Users\UserName\Path\To\File.txt" #Else Cons...

If you are optimizing all images manually, disable APT Cruncher for a smaller APK file size. android { aaptOptions { cruncherEnabled = false } }

In the early forms of Fortran the only mechanism for creating global variable store visible from subroutines and functions is to use the COMMON block mechanism. This permitted sequences of variables to be names and shared in common. In addition to named common blocks there may also be a blank (unna...

This is very common, you memorize a path to a file or folder, you open up Vim and try to write what you've just memorized, but you are not 100% sure it's correct, so you close the editor and start over. When you want the path completion feature, and you have a file /home/ubuntu/my_folder/my_file a...

As the Clang front-end is designed for being compatible with GCC, most programs that can be compiled via GCC will compile when you swap g++ by clang++ in the build scripts. If no -std=version is given, gnu11 will be used. Windows users who are used to MSVC can swap cl.exe with clang-cl.exe. By defa...

Add following record in 'your_file.xml': <openerp> <data> <template id="assets_common" name="your_module_name assets" inherit_id="web.assets_common"> <xpath expr="." position="inside"> <link rel...

The widely used combination of tic and toc can provide a rough idea of the execution time of a function or code snippets. For comparing several functions it shouldn't be used. Why? It is almost impossible to provide equal conditions for all code snippets to compare within a script using above solu...

Python 2 includes a cmp function which allows you to determine if one object is less than, equal to, or greater than another object. This function can be used to pick a choice out of a list based on one of those three options. Suppose you need to print 'greater than' if x > y, 'less than' if x &...

When we want to count the number of items in an iterable, that meet some condition, we can use comprehension to produce an idiomatic syntax: # Count the numbers in `range(1000)` that are even and contain the digit `9`: print (sum( 1 for x in range(1000) if x % 2 == 0 and '9' in str...

Computed GOTO allows branching of the program according to the value of an integer expression. GOTO (label_1, label_2,... label_n) scalar-integer-expression If scalar-integer-expression is equal to 1 the program continues at statement label label_1, if it is equal to 2 it goes to label_2 and so ...

Often you will get into a state where you have a partially typed command sequence in progress, but you want to abort it. You can abort it with either of the following keybindings: C-g EscEscEsc

Comments are programmer-readable annotations that are ignored at runtime. Their purpose is to make source code easier to understand. Single line comments The # character is used to add single line comments. #!/usr/bin/ruby -w # This is a single line comment. puts "Hello World!" Whe...

Command line arguments passed to awk are stored in the internal array ARGV of ARGC elements. The first element of the array is the program name. For example: awk 'BEGIN { for (i = 0; i < ARGC; ++i) { printf "ARGV[%d]=\"%s\"\n", i, ARGV[i] } }' arg1 arg2 arg3 ...

Suppose you have two lists: A and B, and you need to find the elements that exist in both lists. You can do it by just invoking the method List.retainAll(). Example: public static void main(String[] args) { List<Integer> numbersA = new ArrayList<>(); List<Integer> numb...

You can provide help for OpenFileDialog, SaveFileDialog and ColorDialog. To do so set ShowHelp property of dialog to true and handle HelpRequest event for dialog: void openFileDialog1_HelpRequest(object sender, EventArgs e) { //Perform custom action Help.ShowHelp(this, "Http://examp...

Before we download and install Composer, we need to make sure our server has all dependencies installed. First, update the package manager cache by running: sudo apt-get update Now, let's install the dependencies. We'll need curl in order to download Composer and php5-cli for installing and run...

This command: :s/foo/bar/g substitutes each occurrence of foo with bar on the current line. fool around with a foodie becomes barl around with a bardie If you leave off the last /g, it will only replace the first occurence on the line. For example, :s/foo/bar On the previous line wou...

Command line You can use cpan to install modules directly from the command line: cpan install DBI This would be followed by possibly many pages of output describing exactly what it is doing to install the module. Depending on the modules being installed, it may pause and ask you questions. Int...

The code below implements a very simple complex number type for which the underlying field is automatically promoted, following the language's type promotion rules, under application of the four basic operators (+, -, *, and /) with a member of a different field (be it another complex<T> or so...
