Example: Binary text A binary-to-text encoding is encoding of data in plain text. More precisely, it is an encoding of binary data in a sequence of printable characters. These encodings are necessary for transmission of data when the channel does not allow binary data (such as email or NNTP) or is not 8-bit clean. PGP documentation (RFC 4880) uses the term "ASCII armor" for binary-to-text encoding when referring to Base64.

Answer : Updated 2018 The dropdown-submenu has been removed in Bootstrap 3 RC. In the words of Bootstrap author Mark Otto.. "Submenus just don't have much of a place on the web right now, especially the mobile web. They will be removed with 3.0" - https://github.com/twbs/bootstrap/pull/6342 But, with a little extra CSS you can get the same functionality. Bootstrap 4 (navbar submenu on hover) .navbar-nav li:hover > ul.dropdown-menu { display: block; } .dropdown-submenu { position:relative; } .dropdown-submenu>.dropdown-menu { top:0; left:100%; margin-top:-6px; } Navbar submenu dropdown hover Navbar submenu dropdown hover (right aligned) Navbar submenu dropdown click (right aligned) Navbar dropdown hover (no submenu) Bootstrap 3 Here is an example that uses 3.0 RC 1: http://bootply.com/71520 Here is an example that uses Bootstrap 3.0.0 (final): http://bootply.com/86684 CSS .dropdown-submenu { position:relativ

Answer : Use nargs='?' (or nargs='*' if you need more than one dir) parser.add_argument('dir', nargs='?', default=os.getcwd()) extended example: >>> import os, argparse >>> parser = argparse.ArgumentParser() >>> parser.add_argument('-v', action='store_true') _StoreTrueAction(option_strings=['-v'], dest='v', nargs=0, const=True, default=False, type=None, choices=None, help=None, metavar=None) >>> parser.add_argument('dir', nargs='?', default=os.getcwd()) _StoreAction(option_strings=[], dest='dir', nargs='?', const=None, default='/home/vinay', type=None, choices=None, help=None, metavar=None) >>> parser.parse_args('somedir -v'.split()) Namespace(dir='somedir', v=True) >>> parser.parse_args('-v'.split()) Namespace(dir='/home/vinay', v=True) >>> parser.parse_args(''.split()) Nam

Answer : You would simply use jQuery like so... <script> jQuery(function(){ jQuery('#modal').click(); }); </script> Use the click function to auto-click the #modal button JavaScript Pure: <script type="text/javascript"> document.getElementById("modal").click(); </script> JQuery: <script type="text/javascript"> $(document).ready(function(){ $("#modal").trigger('click'); }); </script> or <script type="text/javascript"> $(document).ready(function(){ $("#modal").click(); }); </script> Use the following code $("#modal").trigger('click');

Answer : You can install a module (which is essentially a group of packages) by adding a @ prior to the name of the module to the name parameter of the Ansible dnf module. It can be used like this: - name: install the 'Development tools' package group dnf: name: '@Development tools' state: present

Answer : ID is an attribute, you can set it with the attr function: $(element).attr('id', 'newID'); I'm not sure what you mean about adding IDs since an element can only have one identifier and this identifier must be unique. do you mean a method? $('div.foo').attr('id', 'foo123'); Just be careful that you don't set multiple elements to the same ID. Like this : var id = $('div.foo').attr('id'); $('div.foo').attr('id', id + ' id_adding'); get actual ID put actuel ID and add the new one

Example 1: alert in php echo '<script>alert("Message")</script>' ; Example 2: show alert in php echo '<script language="javascript">alert("juas");</script>' ; Example 3: alert in php // This is in the PHP file and sends a Javascript alert to the client $message = "Something" ; echo "<script type='text/javascript'>alert(' $message ');</script>" ; Example 4: alert js in php javascript : alert ( 'Email enviado com Sucesso!' ) ; javascript : window . location = 'index.php' ;

Example 1: allocate memory c // Use malloc to allocate memory ptr = ( castType * ) malloc ( size ) ; int * exampl = ( int * ) malloc ( sizeof ( int ) ) ; // Use calloc to allocate and inizialize n contiguous blocks of memory ptr = ( castType * ) calloc ( n , size ) ; char * exampl = ( char * ) calloc ( 20 , sizeof ( char ) ) ; Example 2: how to dynamically allocate array size in c // declare a pointer variable to point to allocated heap space int * p_array ; double * d_array ; // call malloc to allocate that appropriate number of bytes for the array p_array = ( int * ) malloc ( sizeof ( int ) * 50 ) ; // allocate 50 ints d_array = ( int * ) malloc ( sizeof ( double ) * 100 ) ; // allocate 100 doubles // use [] notation to access array buckets // (THIS IS THE PREFERED WAY TO DO IT) for ( i = 0 ; i < 50 ; i ++ ) { p_array [ i ] = 0 ; } // you can use pointer arithmetic (but in general don't) double * dptr = d_array

Answer : If you want to do your query synchronously and not receive notifications of updates on the dataset, just don't wrap you return value in a LiveData object. Check out the sample code from Google. Take a look at loadProductSync() here There is a way to turn off async and allow synchronous access. when building the database you can use :allowMainThreadQueries() and for in memory use: Room.inMemoryDatabaseBuilder() Although its not recommended. So in the end i can use a in memory database and main thread access if i wanted super fast access. i guess it depends how big my data is and in this case is very small. but if you did want to use a callback.... using rxJava here is one i made for a list of countries i wanted to store in a database: public Observable<CountryModel> queryCountryInfoFor(final String isoCode) { return Observable.fromCallable(new Callable<CountryModel>() { @Override public CountryModel call() throws Exception {

Example 1: python add to list list_to_add . append ( item_to_add ) # or list_to_add . push ( item_to_add ) Example 2: how to append list in python list1 = [ "hello" ] list1 = list1 + [ "world" ] Example 3: how to add number in tuple a = ( '2' , ) b = 'z' new = a + ( b , ) Example 4: how to add strings in tuple in python First , convert tuple to list by built - in function list ( ) . You can always append item to list object . Then use another built - in function tuple ( ) to convert this list object back to tuple . You can see new element appended to original tuple representation . by tutorialspoint . com happy coding : D

Answer : You can make use of differenceWith() with an isEqual() comparator, and invoke isEmpty to check if they are equal or not. var isArrayEqual = function(x, y) { return _(x).differenceWith(y, _.isEqual).isEmpty(); }; var result1 = isArrayEqual( [{a:1, b:2}, {c:3, d:4}], [{b:2, a:1}, {d:4, c:3}] ); var result2 = isArrayEqual( [{a:1, b:2, c: 1}, {c:3, d:4}], [{b:2, a:1}, {d:4, c:3}] ); document.write([ '<div><label>result1: ', result1, '</label></div>', '<div><label>result2: ', result2, '</label></div>', ].join('')); <script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.11.2/lodash.js"></script> UPDATE June 22, 2018 This update is in response to the comment below: @ryeballar if any of the array is undefined it returns true. How would you solve this. Thanks in advance buddy As stated in the differenceWith documentation:
