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 - ...

from __future__ import print_function import threading def counter(count): while count > 0: print("Count value", count) count -= 1 return t1 = threading.Thread(target=countdown,args=(10,)) t1.start() t2 = threading.Thread(target=countdown,args=(20,)) ...

private Typeface myFont; // A good practice might be to call this in onCreate() of a custom // Application class and pass 'this' as Context. Your font will be ready to use // as long as your app lives public void initFont(Context context) { myFont = Typeface.createFromAsset(context.getAss...

using the vibrate(long[] pattern, int repeat) Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); // Start time delay // Vibrate for 500 milliseconds // Sleep for 1000 milliseconds long[] pattern = {0, 500, 1000}; // 0 meaning is repeat indefinitely vibrator.vib...

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...

Thus these variables will use dynamic binding. (defparameter count 0) ;; All uses of count will refer to this one (defun handle-number (number) (incf count) (format t "~&~d~%" number)) (dotimes (count 4) ;; count is shadowed, but still special (handle-number coun...

Remember, all the best practices of typical web architecture still apply. For an excellent overview on the subject, please refer to Michael Nygard's excellent book Release It! Design and Deploy Production-Ready Software. Writing your app in Meteor doesn't absolve you of auditing third party librarie...

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 Vba7 Then ' It's important to check for Win64 first, ' because Win32 will also return true when Win64 does. #If Win64 Then Declare PtrSafe Function GetFoo64 Lib "exampleLib32" () As LongLong #Else Declare PtrSafe Function GetFoo Lib "exampl...

You can use Bash Parameter Expansion to emulate common filename-processing operations like basename and dirname. We will use this as our example path: FILENAME="/tmp/example/myfile.txt" To emulate dirname and return the directory name of a file path: echo "${FILENAME%/*}" ...

Another use of RODBC is in connecting with SQL Server Management Database. We need to specify the 'Driver' i.e. SQL Server here, the database name "Atilla" and then use the sqlQuery to extract either the full table or a fraction of it. library(RODBC) cn <- odbcDriverConnect(connect...

Variables in Visual Basic are declared using the Dim keyword. For example, this declares a new variable called counter with the data type Integer: Dim counter As Integer A variable declaration can also include an access modifier, such as Public, Protected, Friend, or Private.
