The most simple way to create a thread is by calling a selector "in the background". This means a new thread is created to execute the selector. The receiving object can be any object, not just self, but it needs to respond to the given selector. - (void)createThread { [self performS...

Using a subclass of NSThread allows implementation of more complex threads (for example, to allow passing more arguments or to encapsulate all related helper methods in one class). Additionally, the NSThread instance can be saved in a property or variable and can be queried about its current state ...

$ mkdir 20{09..11}-{01..12} Entering the ls command will show that the following directories were created: 2009-01 2009-04 2009-07 2009-10 2010-01 2010-04 2010-07 2010-10 2011-01 2011-04 2011-07 2011-10 2009-02 2009-05 2009-08 2009-11 2010-02 2010-05 2010-08 2010-11 2011-02 2011-05 2011-08 2011...

// Include the MFC header: // (you do not need to and should not include the standard Windows headers, e.g. // Windows.h) #include <AfxWin.h> // MFC core and standard components // The following header defines resource constants, such as dialog and control IDs: #include &qu...

An indeterminate ProgressBar shows a cyclic animation without an indication of progress. Basic indeterminate ProgressBar (spinning wheel) <ProgressBar android:id="@+id/progressBar" android:indeterminate="true" android:layout_width="wrap_content" ...

A determinate ProgressBar shows the current progress towards a specific maximum value. Horizontal determinate ProgressBar <ProgressBar android:id="@+id/progressBar" android:indeterminate="false" android:layout_width="match_parent" android:layout...

First, create a key file, e.g., vault_pass_file, which ideally contains a long sequence of random characters. In linux systems you could use pwgen to create a random password file: pwgen 256 1 > vault_pass_file Then, use this file to encrypt sensitive data, e.g., groups_vars/group.yml: ANSI...

With Vault you can also encrypt non-structured data, such as private key files and still be able to decrypt them in your play with the lookup module. --- - name: Copy private key to destination copy: dest=/home/user/.ssh/id_rsa mode=0600 content=lookup('pipe', 'ANSIBLE_VAULT_PA...

You can run a play which relies on vault-encrypted templates by using the local_action module. --- - name: Decrypt template local_action: "shell {{ view_encrypted_file_cmd }} {{ role_path }}/templates/template.enc > {{ role_path }}/templates/template" changed_when: False - ...

Go to the (project folder) Then app -> src -> main. Create folder 'assets -> fonts' into the main folder. Put your 'fontfile.ttf' into the fonts folder.

You can create vibration patterns by passing in an array of longs, each of which represents a duration in milliseconds. The first number is start time delay. Each array entry then alternates between vibrate, sleep, vibrate, sleep, etc. The following example demonstrates this pattern: vibrate 100...

If you want stop vibrate please call : vibrator.cancel();

Protocol oriented programing can be used as a core Swift design pattern. Different types are able to conform to the same protocol, value types can even conform to multiple protocols and even provide default method implementation. Initially protocols are defined that can represent commonly used pro...
