If you're using a jupyter notebook, I found this to be the simplest solution for one off cases. Basically convert the numpy array to a list and then to a string and then print. This has the benefit of keeping the comma separators in the array, whereas using numpyp.printoptions(threshold=np.inf) does not:

import numpy as np
print(str(np.arange(10000).reshape(250,40).tolist()))

Use pd.set_option('display.max_colwidth', None) for automatic linebreaks and multi-line cells.

This is a great resource on how to use jupyters display with pandas to the fullest.

Edited: Used to be pd.set_option('display.max_colwidth', -1).

The link to a function in a dynamic library is resolved when the library is loaded or at run time. Therefore, both the executable file and dynamic library are loaded into memory when the program is run. The memory address at which a dynamic library is loaded cannot be determined in advance, because a fixed address might clash with another dynamic library requiring the same address.

There are two commonly used methods for dealing with this problem:

1.Relocation. All pointers and addresses in the code are modified, if necessary, to fit the actual load address. Relocation is done by the linker and the loader.

2.Position-independent code. All addresses in the code are relative to the current position. Shared objects in Unix-like systems use position-independent code by default. This is less efficient than relocation if program run for a long time, especially in 32-bit mode.

The name "position-independent code" actually implies following:

• The code section contains no absolute addresses that need relocation, but only self relative addresses. Therefore, the code section can be loaded at an arbitrary memory address and shared between multiple processes.

• The data section is not shared between multiple processes because it often contains writeable data. Therefore, the data section may contain pointers or addresses that need relocation.

• All public functions and public data can be overridden in Linux. If a function in the main executable has the same name as a function in a shared object, then the version in main will take precedence, not only when called from main, but also when called from the shared object. Likewise, when a global variable in main has the same name as a global variable in the shared object, then the instance in main will be used, even when accessed from the shared object.

This so-called symbol interposition is intended to mimic the behavior of static libraries.

A shared object has a table of pointers to its functions, called procedure linkage table (PLT) and a table of pointers to its variables called global offset table (GOT) in order to implement this "override" feature. All accesses to functions and public variables go through this tables.

p.s. Where dynamic linking cannot be avoided, there are various ways to avoid the timeconsuming features of the position-independent code.

What you first tried should work, but the HTML is not what we would expect. I added an option to handle the initial "no item selected" case:

<select ng-options="region.code as region.name for region in regions" ng-model="region">
   <option style="display:none" value="">select a region</option>
</select>
<br>selected: {{region}}

The above generates this HTML:

<select ng-options="..." ng-model="region" class="...">
   <option style="display:none" value class>select a region</option>
   <option value="0">Alabama</option>
   <option value="1">Alaska</option>
   <option value="2">American Samoa</option>
</select>

Fiddle

Even though Angular uses numeric integers for the value, the model (i.e., $scope.region) will be set to AL, AK, or AS, as desired. (The numeric value is used by Angular to lookup the correct array entry when an option is selected from the list.)

This may be confusing when first learning how Angular implements its "select" directive.

What about html data attributes? That's the easiest way. Reference from w3school

In your case

$('select').on('change', function() {_x000D_
  alert('value a is:' + $("select option:selected").data('valuea') +_x000D_
    '\nvalue b is:' + $("select option:selected").data('valueb')_x000D_
  )_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script>_x000D_
<select name="Testing">_x000D_
  <option value="1" data-valuea="2010" data-valueb="2011"> One_x000D_
    <option value="2" data-valuea="2122" data-valueb="2123"> Two_x000D_
      <option value="3" data-valuea="0" data-valueb="1"> Three_x000D_
</select>

you can print it in Rstudio with View() more convenient:

df %>% View()

View(df)

According to Reddit, more options icon and kabob menu are popular names. I prefer the latter as it goes well with hamburger menu.

I just found this extension called beautify in the Market Place and yes, it's another config\settings file. :)

Beautify javascript, JSON, CSS, Sass, and HTML in Visual Studio Code.

VS Code uses js-beautify internally, but it lacks the ability to modify the style you wish to use. This extension enables running js-beautify in VS Code, AND honouring any .jsbeautifyrc file in the open file's path tree to load your code styling. Run with F1 Beautify (to beautify a selection) or F1 Beautify file.

For help on the settings in the .jsbeautifyrc see Settings.md

Here is the GitHub repository: https://github.com/HookyQR/VSCodeBeautify

try this function

public static Date StringToDate(String strDate) throws ModuleException {
    Date dtReturn = null;
    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-mm-dd");
    try {
        dtReturn = simpleDateFormat.parse(strDate);
    } catch (ParseException e) {
        e.printStackTrace();
    }
    return dtReturn;
}

The best way to force the use of a number composed of digits only:

<input type="number" onkeydown="javascript: return event.keyCode === 8 ||_x000D_
event.keyCode === 46 ? true : !isNaN(Number(event.key))" />

this avoids 'e', '-', '+', '.' ... all characters that are not numbers !

To allow number keys only:

isNaN(Number(event.key))

but accept "Backspace" (keyCode: 8) and "Delete" (keyCode: 46) ...

You can use the styleSheets object:

document.styleSheets[0].cssRules[0].style.removeProperty("zoom");

Caveat #1: You have to know the index of your stylesheet and the index of your rule.

Caveat #2: This object is implemented inconsistently by the browsers; what works in one may not work in the others.

On your storyboard page, go to File Inspector and uncheck 'Use Size Classes'. This should shrink your view controller to regular IPhone size you were familiar with. Note that using 'size classes' will let you design your project across many devices. Once you uncheck this the Xcode will give you a warning dialogue as follows. This should be self-explainatory.

"Disabling size classes will limit this document to storing data for a single device family. The data for the size class best representing the targeted device will be retained, and all other data will be removed. In addition, segues will be converted to their non-adaptive equivalents."

Don't use setSupportActionBar(toolbar)

I don't know why but this works for me.

toolbar = (Toolbar) findViewById(R.id.main_toolbar);
toolbar.setSubtitle("Test Subtitle");
toolbar.inflateMenu(R.menu.main_manu);

For menu item click do this

toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {

        @Override
        public boolean onMenuItemClick(MenuItem item) {

            if(item.getItemId()==R.id.item1)
            {
                // do something
            }
            else if(item.getItemId()== R.id.filter)
            {
               // do something
            }
            else{
               // do something
            }

            return false;
        }
    });

Will update the 'why' part of this answer when I find a proper explanation.
Happy to help anyway :) Peace.

I would choose this simple solution.

Summarizing it:

• Client "I want to login"
• Server generates a random number #S and sends it to the Client
• Client
  • reads username and password typed by the user
  • calculates the hash of the password, getting h(pw) (which is what is stored in the DB)
  • generates another random number #C
  • concatenates h(pw) + #S + #C and calculates its hash, call it h(all)
  • sends to the server username, #C and h(all)
• Server
  • retrieves h(pw)' for the specified username, from the DB
  • now it has all the elements to calculate h(all'), like Client did
  • if h(all) = h(all') then h(pw) = h(pw)', almost certainly

No one can repeat the request to log in as the specified user. #S adds a variable component to the hash, each time (it's fundamental). #C adds additional noise in it.

var startDate = moment(startDateVal, "DD.MM.YYYY");//Date format
var endDate = moment(endDateVal, "DD.MM.YYYY");

var isAfter = moment(startDate).isAfter(endDate);

if (isAfter) {
    window.showErrorMessage("Error Message");
    $(elements.endDate).focus();
    return false;
}

So you cant have the behavior that you want but you can do something that feels like it. You want to be able to do Choice.first.question

what I have done in the past is something like this

class Choice
  belongs_to :user
  belongs_to :answer
  validates_uniqueness_of :answer_id, :scope => [ :question_id, :user_id ]
  ...
  def question
    answer.question
  end
end

this way the you can now call question on Choice

Fromthe Javadoc of Method.invoke():

If the underlying method is static, then the specified obj argument is ignored. It may be null.

What happens when you

Class klass = ...;
Method m = klass.getDeclaredMethod(methodName, paramtypes);
m.invoke(null, args)

If you want to be able to choose from different solutions, in addition to the given answers...

An alternative method is to give the container a width of 0 and to make sure overflow is visible. Then each word will overflow out of it and will be on its own line.

div {_x000D_
  width: 0;_x000D_
  overflow: visible;_x000D_
}

<div>Short Word</div>_x000D_
<hr>_x000D_
<div>Gargantuan Word</div>

Or you can use one of those newly proposed width values, provided those still exist by the time you read this.

div {_x000D_
  width: min-intrinsic;       /* old Chrome, Safari */_x000D_
  width: -webkit-min-content; /* less old Chrome, Safari */_x000D_
  width: -moz-min-content;    /* current Firefox */_x000D_
  width: min-content;         /* current Chrome, Safari; not IE or Edge */_x000D_
}

<div>Short Word</div>_x000D_
<hr>_x000D_
<div>Gargantuan Word</div>

You'd think this would be a simple question to answer, with everything else that jQuery can do. Unfortunately, the problem comes down to a technical issue: css :after and :before rules aren't part of the DOM, and therefore can't be altered using jQuery's DOM methods.

There are ways to manipulate these elements using JavaScript and/or CSS workarounds; which one you use depends on your exact requirements.

I'm going to start with what's widely considered the "best" approach:

1) Add/remove a predetermined class

In this approach, you've already created a class in your CSS with a different :after or :before style. Place this "new" class later in your stylesheet to make sure it overrides:

p:before {
    content: "foo";
}
p.special:before {
    content: "bar";
}

Then you can easily add or remove this class using jQuery (or vanilla JavaScript):

$('p').on('click', function() {
    $(this).toggleClass('special');
});

    $('p').on('click', function() {_x000D_
      $(this).toggleClass('special');_x000D_
    });

p:before {_x000D_
  content: "foo";_x000D_
  color: red;_x000D_
  cursor: pointer;_x000D_
}_x000D_
p.special:before {_x000D_
  content: "bar";_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<p>This is a paragraph.</p>_x000D_
<p>This is another paragraph.</p>

• Pros: Easy to implement with jQuery; quickly alters multiple styles at once; enforces separation of concerns (isolating your CSS and JS from your HTML)
• Cons: CSS must be pre-written, so the content of :before or :after isn't completely dynamic

2) Add new styles directly to the document's stylesheet

It's possible to use JavaScript to add styles directly to the document stylesheet, including :after and :before styles. jQuery doesn't provide a convenient shortcut, but fortunately the JS isn't that complicated:

var str = "bar";
document.styleSheets[0].addRule('p.special:before','content: "'+str+'";');

var str = "bar";_x000D_
document.styleSheets[0].addRule('p.special:before', 'content: "' + str + '";');

p:before {_x000D_
  content: "foo";_x000D_
  color: red;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<p class="special">This is a paragraph</p>_x000D_
<p>This is another paragraph</p>

.addRule() and the related .insertRule() methods are fairly well-supported today.

As a variation, you can also use jQuery to add an entirely new stylesheet to the document, but the necessary code isn't any cleaner:

var str = "bar";
$('<style>p.special:before{content:"'+str+'"}</style>').appendTo('head');

var str = "bar";_x000D_
$('<style>p.special:before{content:"' + str + '"}</style>').appendTo('head');

p:before {_x000D_
  content: "foo";_x000D_
  color: red;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<p class="special">This is a paragraph</p>_x000D_
<p>This is another paragraph</p>

If we're talking about "manipulating" the values, not just adding to them, we can also read the existing :after or :before styles using a different approach:

var str = window.getComputedStyle(document.querySelector('p'), ':before') 
           .getPropertyValue('content');

var str = window.getComputedStyle($('p')[0], ':before').getPropertyValue('content');_x000D_
console.log(str);_x000D_
_x000D_
document.styleSheets[0].addRule('p.special:before', 'content: "' + str+str + '";');

p:before {_x000D_
    content:"foo";_x000D_
    color: red;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<p class="special">This is a paragraph</p>_x000D_
<p>This is another paragraph</p>

We can replace document.querySelector('p') with $('p')[0] when using jQuery, for slightly shorter code.

• Pros: any string can be dynamically inserted into the style
• Cons: original styles aren't altered, just overridden; repeated (ab)use can make the DOM grow arbitrarily large

3) Alter a different DOM attribute

You can also to use attr() in your CSS to read a particular DOM attribute. (If a browser supports :before, it supports attr() as well.) By combining this with content: in some carefully-prepared CSS, we can change the content (but not other properties, like margin or color) of :before and :after dynamically:

p:before {
    content: attr(data-before);
    color: red;
    cursor: pointer;
}

JS:

$('p').on('click', function () {
    $(this).attr('data-before','bar');
});

$('p').on('click', function () {_x000D_
    $(this).attr('data-before','bar');_x000D_
});

p:before {_x000D_
    content: attr(data-before);_x000D_
    color: red;_x000D_
    cursor: pointer;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<p>This is a paragraph.</p>_x000D_
<p>This is another paragraph.</p>

This can be combined with the second technique if the CSS can't be prepared ahead of time:

var str = "bar";

document.styleSheets[0].addRule('p:before', 'content: attr(data-before);');

$('p').on('click', function () {
    $(this).attr('data-before', str);
});

var str = "bar";_x000D_
document.styleSheets[0].addRule('p:before', 'content: attr(data-before) !important;');_x000D_
_x000D_
$('p').on('click', function() {_x000D_
  $(this).attr('data-before', str);_x000D_
});

p:before {_x000D_
  content: "foo";_x000D_
  color: red;_x000D_
  cursor: pointer;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<p>This is a paragraph.</p>_x000D_
<p>This is another paragraph.</p>

• Pros: Doesn't create endless extra styles
• Cons: attr in CSS can only apply to content strings, not URLs or RGB colors

<?php
    if(isset($_POST['mail']) && $_POST['mail']!='') {
        echo "Yes, mail is set";
    }else{
        echo "N0, mail is not set";
    }
?>

Just wanted to illustrate, in the context of nested lists, the usefulness of the hidden checkbox <input> approach @jeffmcneill recommends — a context where each shown/hidden element should hold its state independently of focus and the show/hide state of other elements on the page.

Giving values with a common set of beginning characters to the id attributes of all the checkboxes used for the shown/hidden elements on the page lets you use an economical [id^=""] selector scheme for the stylesheet rules that toggle your clickable element’s appearance and the related shown/hidden element’s display state back and forth. Here, my ids are ‘expanded-1,’ ‘expanded-2,’ ‘expanded-3.’

Note that I’ve also used @Diepen’s :after selector idea in order to keep the <label> element free of content in the html.

Note also that the <input> <label> <div class="collapsible"> sequence matters, and the corresponding CSS with + selector instead of ~.

Statistic plugins works fine!

Here is a quick case:

1. Ctrl+Shift+A and serach for "Statistic" to open the panel.
2. You will see panel as the screenshot and then click Refresh for whole project or select your project or file and Refresh on selection for only selection.

Here is an ES2017+ way to get the counts for all array items in O(N):

const arr = [1, 2, 3, 5, 2, 8, 9, 2];
const counts = {};

arr.forEach((el) => {
  counts[el] = counts[el] ? (counts[el] += 1) : 1;
});

You can also optionally sort the output:

const countsSorted = Object.entries(counts).sort(([_, a], [__, b]) => a - b);

console.log(countsSorted) for your example array:

[
  [ '2', 3 ],
  [ '1', 1 ],
  [ '3', 1 ],
  [ '5', 1 ],
  [ '8', 1 ],
  [ '9', 1 ]
]

The nature of wanting to include the row where A == 5 and all rows upto but not including the row where A == 8 means we will end up using iloc (loc includes both ends of slice).

In order to get the index labels we use idxmax. This will return the first position of the maximum value. I run this on a boolean series where A == 5 (then when A == 8) which returns the index value of when A == 5 first happens (same thing for A == 8).

Then I use searchsorted to find the ordinal position of where the index label (that I found above) occurs. This is what I use in iloc.

i5, i8 = df.index.searchsorted([df.A.eq(5).idxmax(), df.A.eq(8).idxmax()])
df.iloc[i5:i8]

numpy

you can further enhance this by using the underlying numpy objects the analogous numpy functions. I wrapped it up into a handy function.

def find_between(df, col, v1, v2):
    vals = df[col].values
    mx1, mx2 = (vals == v1).argmax(), (vals == v2).argmax()
    idx = df.index.values
    i1, i2 = idx.searchsorted([mx1, mx2])
    return df.iloc[i1:i2]

find_between(df, 'A', 5, 8)

timing

Found these docu on the google docu pages:

• row --- int --- top row of the range
• column --- int--- leftmost column of the range
• optNumRows --- int --- number of rows in the range.
• optNumColumns --- int --- number of columns in the range

In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns

edit

Using the example on the docu:

// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);

The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G

So you come to the range: C2:G8

Suppose you have following lines of code

MyUrl = "www.google.com" #Your url goes here
urllib.urlretrieve(MyUrl)

If you are receiving following error message

AttributeError: module 'urllib' has no attribute 'urlretrieve'

Then you should try following code to fix the issue:

import urllib.request
MyUrl = "www.google.com" #Your url goes here
urllib.request.urlretrieve(MyUrl)

This should work if current file is located in same directory where initcontrols is:

<?php
$ds = DIRECTORY_SEPARATOR;
$base_dir = realpath(dirname(__FILE__)  . $ds . '..') . $ds;
require_once("{$base_dir}initcontrols{$ds}config.php");
?>
<div>
<?php 
$file = "{$base_dir}initcontrols{$ds}header_myworks.php"; 
include_once($file); 
echo $plHeader;?>   
</div>

A simple solution in pandas is to use the sample method independently on each column. Use apply to iterate over each column:

df = pd.DataFrame({'a':[1,2,3,4,5,6], 'b':[1,2,3,4,5,6]})
df

   a  b
0  1  1
1  2  2
2  3  3
3  4  4
4  5  5
5  6  6

df.apply(lambda x: x.sample(frac=1).values)

   a  b
0  4  2
1  1  6
2  6  5
3  5  3
4  2  4
5  3  1

You must use .value so that you return a numpy array and not a Series, or else the returned Series will align to the original DataFrame not changing a thing:

df.apply(lambda x: x.sample(frac=1))

   a  b
0  1  1
1  2  2
2  3  3
3  4  4
4  5  5
5  6  6

I'm using moment in my react project

import moment from 'moment'

state = {
    startDate: moment()
};
render() {
    const selectedDate = this.state.startDate.format("Do MMMM YYYY");
    return(
     <Fragment>
       {selectedDate)
     </Fragment>
   );
}

You may want to take a look at Pyschools, the website has quite a lot of practice questions on Python Programming.

$users = Users::get();

$subset = $users->map(function ($user) {
    return array_only(user, ['id', 'name', 'email']);
});

##To check for a particular  string in a file

cd PATH_TO_YOUR_DIRECTORY #Changing directory to your working directory
File=YOUR_FILENAME  
if grep -q STRING_YOU_ARE_CHECKING_FOR "$File"; ##note the space after the string you are searching for
then
echo "Hooray!!It's available"
else
echo "Oops!!Not available"
fi

I was looking for the same thing and I've just seen that MySQL 5.6 has a couple of new string functions supporting this functionality: TO_BASE64 and FROM_BASE64.

Pure JSP comments look like this:

<%-- Comment --%>

So if you want to retain the "=".you could do something like:

<%--= map.size() --%>

The key thing is that <%= defines the beginning of an expression, in which you can't leave the body empty, but you could do something like this instead if the pure JSP comment doesn't appeal to you:

<% /*= map.size()*/ %>

Code Conventions for the JavaServer Pages Technology Version 1.x Language has details about the different commenting options available to you (but has a complete lack of link targets, so I can't link you directly to the relevant section - boo!)

If you want to go with the add-open option, here's a command to find which module provides which package ->

java --list-modules | tr @ " " | awk '{ print $1 }' | xargs -n1 java -d

the name of the module will be shown with the @ while the name of the packages without it

NOTE: tested with JDK 11

IMPORTANT: obviously is better than the provider of the package does not do the illegal access

Can you include some code? I add style="display:none;" to my table rows all the time and it effectively hides the entire row.

Using Erik's answer, as a starting point. I found a simpler solution that worked for me.

In my ng-click function I have:

var the_string = 'lifeMeaning';
if ($scope[the_string] === undefined) {
   //Valid in my application for first usage
   $scope[the_string] = true;
} else {
   $scope[the_string] = !$scope[the_string];
}
//$scope.$apply

I've tested it with and without $scope.$apply. Works correctly without it!

You can do:

#if MACRO0
    //code...
#elif MACRO1
    //code...
#endif

…where the identifier can be:

    __linux__       Defined on Linux
    __sun           Defined on Solaris
    __FreeBSD__     Defined on FreeBSD
    __NetBSD__      Defined on NetBSD
    __OpenBSD__     Defined on OpenBSD
    __APPLE__       Defined on Mac OS X
    __hpux          Defined on HP-UX
    __osf__         Defined on Tru64 UNIX (formerly DEC OSF1)
    __sgi           Defined on Irix

The keytool command will not allow you to export the private key from a key store. You have to write some Java code to do this. Open the key store, get the key you need, and save it to a file in PKCS #8 format. Save the associated certificate too.

KeyStore ks = KeyStore.getInstance("jks");
/* Load the key store. */
...
char[] password = ...;
/* Save the private key. */
FileOutputStream kos = new FileOutputStream("tmpkey.der");
Key pvt = ks.getKey("your_alias", password);
kos.write(pvt.getEncoded());
kos.flush();
kos.close();
/* Save the certificate. */
FileOutputStream cos = new FileOutputStream("tmpcert.der");
Certificate pub = ks.getCertificate("your_alias");
cos.write(pub.getEncoded());
cos.flush();
cos.close();

Use OpenSSL utilities to convert these files (which are in binary format) to PEM format.

openssl pkcs8 -inform der -nocrypt < tmpkey.der > tmpkey.pem
openssl x509 -inform der < tmpcert.der > tmpcert.pem

It seem like your Resort method doesn't declare a compareTo method. This method typically belongs to the Comparable interface. Make sure your class implements it.

Additionally, the compareTo method is typically implemented as accepting an argument of the same type as the object the method gets invoked on. As such, you shouldn't be passing a String argument, but rather a Resort.

Alternatively, you can compare the names of the resorts. For example

if (resortList[mid].getResortName().compareTo(resortName)>0)  

Toastr is a very nice component, and you can show messages with theses commands:

// for success - green box
toastr.success('Success messages');

// for errors - red box
toastr.error('errors messages');

// for warning - orange box
toastr.warning('warning messages');

// for info - blue box
toastr.info('info messages');

If you want to provide a title on the toastr message, just add a second argument:

// for info - blue box
toastr.success('The process has been saved.', 'Success');

you also can change the default behaviour using something like this:

toastr.options.timeOut = 3000; // 3s

See more on the github of the project.

Edits

A sample of use:

$(document).ready(function() {

    // show when page load
    toastr.info('Page Loaded!');

    $('#linkButton').click(function() {
       // show when the button is clicked
       toastr.success('Click Button');

    });

});

and a html:

<a id='linkButton'>Show Message</a>

nmap can discover the MAC address of a remote target only if

• the target is on the same link as the machine nmap runs on, or
• the target leaks this information through SNMP, NetBIOS etc.

Another possibility comes with IPv6 if the target uses EUI-64 identifiers, then the MAC address can be deduced from the IP address.

Apart from the above possibilities, there is no reliable way to obtain the MAC address of a remote target with network scanning techniques.

This problem explained in MSDN Library and as I understand installing Microsoft's Redistributable Package can help.

But sometimes the following solution can be used (as developer's side solution):

In your Visual Studio, open Project properties -> Configuration properties -> C/C++ -> Code generation and change option Runtime Library to /MT instead of /MD

Try with it

$color = \App\Color::take(1)->first();

First, you aren't actually creating 10 buttons. Second, you need to set the location of each button, or they will appear on top of each other. This will do the trick:

  for (int i = 0; i < 10; ++i)
  {
      var button = new Button();
      button.Location = new Point(button.Width * i + 4, 0);
      Controls.Add(button);
  }

Parse a filename from the fully qualified path name (e.g., c:\temp\my.bat) to any component (e.g., File.ext).

Single line of code:

For %%A in ("C:\Folder1\Folder2\File.ext") do (echo %%~fA)

You can change out "C:\Folder1\Folder2\File.ext" for any full path and change "%%~fA" for any of the other options you will find by running "for /?" at the command prompt.

Elaborated Code

set "filename=C:\Folder1\Folder2\File.ext"
For %%A in ("%filename%") do (
    echo full path: %%~fA
    echo drive: %%~dA
    echo path: %%~pA
    echo file name only: %%~nA
    echo extension only: %%~xA
    echo expanded path with short names: %%~sA
    echo attributes: %%~aA
    echo date and time: %%~tA
    echo size: %%~zA
    echo drive + path: %%~dpA
    echo name.ext: %%~nxA
    echo full path + short name: %%~fsA)

Simply use the base transpose function t, wrapped with as.data.frame:

final_df <- as.data.frame(t(starting_df))
final_df
     A    B    C    D
a    1    2    3    4
b 0.02 0.04 0.06 0.08
c Aaaa Bbbb Cccc Dddd

Above updated. As docendo discimus pointed out, t returns a matrix. As Mark suggested wrapping it with as.data.frame gets back a data frame instead of a matrix. Thanks!

I had this issue, and solved. This was due to the WHERE clause contains String value instead of integer value.

For the ones that using Xamarin.IOS you can do like this:

new UIAlertView(null, message, null, "OK", null).Show();

using UIKit; is required.

You can also use

 If EXISTS (SELECT 1 FROM dbo.T1 WHERE T1.Name='Scot')
    BEGIN
         --<Do something>
    END 

ELSE    
     BEGIN
       --<Do something>
     END

Simply type conda update pandas in your preferred shell (on Windows, use cmd; if Anaconda is not added to your PATH use the Anaconda prompt). You can of course use Eclipse together with Anaconda, but you need to specify the Python-Path (the one in the Anaconda-Directory). See this document for a detailed instruction.

you need to download and install jdk from here

HTML 4 does not make it explicit. The current HTML5 working draft specifies that the first submit button must be the default:

A form element's default button is the first submit button in tree order whose form owner is that form element.

If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.

In case someone needs to run over a table and split a field:

1. First we use the function mention above:

CREATE DEFINER=`root`@`localhost` FUNCTION `fn_split_str`($str VARCHAR(800), $delimiter VARCHAR(12), $position INT) RETURNS varchar(800) CHARSET utf8
    DETERMINISTIC
BEGIN 
    RETURN REPLACE(
            SUBSTRING(
                SUBSTRING_INDEX($str, $delimiter, $position),
                LENGTH(
                    SUBSTRING_INDEX($str, $delimiter, $position -1)
                ) + 1
            ),
    $delimiter, '');
END

2. Second, we run in a while loop on the string until there isn't any results (I've added $id for JOIN clause):

CREATE DEFINER=`root`@`localhost` FUNCTION `fn_split_str_to_rows`($id INT, $str VARCHAR(800), $delimiter VARCHAR(12), $empty_table BIT) RETURNS int(11)
BEGIN

    DECLARE position INT;
    DECLARE val VARCHAR(800);
    SET position = 1;
    
    IF $empty_table THEN
        DROP TEMPORARY TABLE IF EXISTS tmp_rows;    
    END IF;
            
    SET val = fn_split_str($str, ',', position);
            
    CREATE TEMPORARY TABLE IF NOT EXISTS tmp_rows AS (SELECT $id as id, val as val where 1 = 2);
        
    WHILE (val IS NOT NULL and val != '') DO               
        INSERT INTO tmp_rows
        SELECT $id, val;
        
        SET position = position + 1;
        SET val = fn_split_str($str, ',', position);
    END WHILE;
    
    RETURN position - 1;
END

3. Finally we can use it like that:

DROP TEMPORARY TABLE IF EXISTS tmp_rows;
SELECT  SUM(fn_split_str_to_rows(ID, FieldToSplit, ',', 0))
FROM    MyTable;

SELECT * FROM tmp_rows;

You can use the id to join to other table.

In case you are only splitting one value you can use it like that

SELECT  fn_split_str_to_rows(null, 'AAA,BBB,CCC,DDD,EEE,FFF,GGG', ',', 1);
SELECT * FROM tmp_rows;

We don't need to empty the temporary table, the function will take care of that.

This may not be what you are looking for, but in the interest of coming at a problem from another angle....

Are these two Java processes that might want to access the same file in the same application? Perhaps you can just filter all access to the file through a single, synchronized method (or, even better, using JSR-166)? That way, you can control access to the file, and perhaps even queue access requests.

FOR MYSQL:

ALTER TABLE `table_name` CHANGE `old_name` `new_name` VARCHAR(255) NOT NULL;

FOR ORACLE:

ALTER TABLE `table_name` RENAME COLUMN `old_name` TO `new_name`;

SELECT *
FROM   B
WHERE  NOT EXISTS (SELECT 1 
                   FROM   A 
                   WHERE  A.ID = B.ID)

Apache Commons allows:

String myString = IOUtils.toString(myInputStream, "UTF-8");

Of course, you could choose other character encodings besides UTF-8.

Also see: (documentation)

There is a way with struct namespace.

The benefit is all enum variables are under a specific namespace to avoid pollution. The issue is that we could only use var not const

type OrderStatusType string

var OrderStatus = struct {
    APPROVED         OrderStatusType
    APPROVAL_PENDING OrderStatusType
    REJECTED         OrderStatusType
    REVISION_PENDING OrderStatusType
}{
    APPROVED:         "approved",
    APPROVAL_PENDING: "approval pending",
    REJECTED:         "rejected",
    REVISION_PENDING: "revision pending",
}

Per the comments to the original post, merges / joins are well-suited for this problem. In particular, an inner join will return only values that are present in both dataframes, making thesetdiff statement unnecessary.

Using the data from Dinre's example:

In base R:

cleanedA <- merge(data_A, data_B[, "index"], by = 1, sort = FALSE)
cleanedB <- merge(data_B, data_A[, "index"], by = 1, sort = FALSE)

Using the dplyr package:

library(dplyr)
cleanedA <- inner_join(data_A, data_B %>% select(index))
cleanedB <- inner_join(data_B, data_A %>% select(index))

To keep the data as two separate tables, each containing only its own variables, this subsets the unwanted table to only its index variable before joining. Then no new variables are added to the resulting table.

You might need to Deserialize your anonymous JSON type from the request body.

var jsonBody = HttpContext.Request.Content.ReadAsStringAsync().Result;
ScoreInputModel myDeserializedClass = JsonConvert.DeserializeObject<ScoreInputModel>(jsonBody);

try this one

    <dependency>
        <groupId>com.hynnet</groupId>

I faced the same issue except that the data type of the instance I wanted to predict was a panda.Series object.

Well I just needed to predict one input instance. I took it from a slice of my data.

df = pd.DataFrame(list(BiogasPlant.objects.all()))
test = df.iloc[-1:]       # sliced it here

In this case, you'll need to convert it into a 1-D array and then reshape it.

 test2d = test.values.reshape(1,-1)

From the docs, values will convert Series into a numpy array.

You can use flexbox in 2018+:

.label-class {
    display: flex;
    align-items: center;
}

Browser support: https://caniuse.com/#search=flexbox

A variable used in lambda expression should be a final or effectively final, but you can assign a value to a final one element array.

private TimeZone extractCalendarTimeZoneComponent(Calendar cal, TimeZone calTz) {
    try {
        TimeZone calTzLocal[] = new TimeZone[1];
        calTzLocal[0] = calTz;
        cal.getComponents().get("VTIMEZONE").forEach(component -> {
            TimeZone v = component;
            v.getTimeZoneId();
            if (calTzLocal[0] == null) {
                calTzLocal[0] = TimeZone.getTimeZone(v.getTimeZoneId().getValue());
            }
        });
    } catch (Exception e) {
        log.warn("Unable to determine ical timezone", e);
    }
    return null;
}

I think since we don't have $rootScope kind of thing in angular 2 as in angular 1.x. We can use angular 2 shared service/class while in ngOnDestroy pass data to service and after routing take the data from the service in ngOnInit function:

Here I am using DataService to share hero object:

import { Hero } from './hero';
export class DataService {
  public hero: Hero;
}

Pass object from first page component:

 ngOnDestroy() {
    this.dataService.hero = this.hero; 
 }

Take object from second page component:

 ngOnInit() {
    this.hero = this.dataService.hero; 
 }

Here is an example: plunker

Just add the onclick-attribute:

<div class="drill_cursor" onclick='alert("youClickedMe!");'>
....
</div>

It's javascript, but it's automatically bound using an html-attribute instead of manually binding it within <script> tags - maybe it does what you want.

While it might be good enough for very small projects or test pages, you should definitly consider using addEventListener (as pointed out by other answers), if you expect the code to grow and stay maintainable.

Use .apply() to have the same access to arguments in function b, like this:

function a(){
    b.apply(null, arguments);
}
function b(){
   alert(arguments); //arguments[0] = 1, etc
}
a(1,2,3);?

You can test it out here.

Using jQuery, and assuming that you have <div id="foo">:

jQuery(function($){
  $('#foo').click(function(e){
    console.log( 'clicked on div' );
    e.stopPropagation(); // Prevent bubbling
  });
  $('body').click(function(e){
    console.log( 'clicked outside of div' );
  });
});

Edit: For a single handler:

jQuery(function($){
  $('body').click(function(e){
    var clickedOn = $(e.target);
    if (clickedOn.parents().andSelf().is('#foo')){
      console.log( "Clicked on", clickedOn[0], "inside the div" );
    }else{
      console.log( "Clicked outside the div" );
  });
});

For me it worked in bash from git package try:

C:\Program Files\Git\bin\bash.exe

then:

npm install mds.angular.datetimepicker@latest

If you remove directives attribute it should work.

@Component({
    selector: 'parent',
    template: `
            <h1>Parent Component</h1>
            <child></child>
        `
    })
    export class ParentComponent{}


@Component({
    selector: 'child',    
    template: `
            <h4>Child Component</h4>
        `
    })
    export class ChildComponent{}

Directives are like components but they are used in attributes. They also have a declarator @Directive. You can read more about directives Structural Directives and Attribute Directives.

There are two other kinds of Angular directives, described extensively elsewhere: (1) components and (2) attribute directives.

A component manages a region of HTML in the manner of a native HTML element. Technically it's a directive with a template.

Also if you are open the glossary you can find that components are also directives.

Directives fall into one of the following categories:

• Components combine application logic with an HTML template to render application views. Components are usually represented as HTML elements. They are the building blocks of an Angular application.

• Attribute directives can listen to and modify the behavior of other HTML elements, attributes, properties, and components. They are usually represented as HTML attributes, hence the name.

• Structural directives are responsible for shaping or reshaping HTML layout, typically by adding, removing, or manipulating elements and their children.

The difference that components have a template. See Angular Architecture overview.

A directive is a class with a @Directive decorator. A component is a directive-with-a-template; a @Component decorator is actually a @Directive decorator extended with template-oriented features.

The @Component metadata doesn't have directives attribute. See Component decorator.

Stay on your ComboBox and search the DropDropStyle property from the properties window and then choose DropDownList.

array = new String[array.length];

$cart = array();
$cart[] = 11;
$cart[] = 15;

// etc

//Above is correct. but below one is for further understanding

$cart = array();
for($i = 0; $i <= 5; $i++){
          $cart[] = $i;  

//if you write $cart = [$i]; you will only take last $i value as first element in array.

}
echo "<pre>";
print_r($cart);
echo "</pre>";

Try GetElementsByTagName method of XMLDocument class to read specific data or LoadXml method to read all data to xml document.

There is a Ubuntu solution available either through the Ubuntu Software Center or through the Synaptic Package Manager. This will connect Python version 3.4.0 to MySQL. Download "python3-mysql.connector" version 1.1.6-1.

Note that the connection syntax does not use "MySQLdb". Instead read: Connecting to MySQL Using Connector/Python

[a-z] matches a single char between a and z. So, if your string was just "d", for example, then it would have matched and been printed out.

You need to change your regex to [a-z]+ to match one or more chars.

Unix will only run commands if they are available on the system path, as you can view by the $PATH variable

echo $PATH

Executables located in directories that are not on the path cannot be run unless you specify their full location. So in your case, assuming the executable is in the current directory you are working with, then you can execute it as such

./my-exec

Where my-exec is the name of your program.

declare @OrderByCmd  nvarchar(2000)
declare @OrderByName nvarchar(100)
declare @OrderByCity nvarchar(100)
set @OrderByName='Name'    
set @OrderByCity='city'
set @OrderByCmd= 'select * from customer Order By '+@OrderByName+','+@OrderByCity+''
EXECUTE sp_executesql @OrderByCmd 

You can use window.open to open a new window/tab(according to browser setting) in javascript.

By using document.write you can write HTML content to the opened window.

no, CURL does not have anything with parsing XML, it does not know anything about the content returned. it serves as a proxy to get content. it's up to you what to do with it.

use JSON if possible (and json_decode) - it's easier to work with, if not possible, use any XML library for parsin such as DOMXML: http://php.net/domxml

package com.mani.smsdetect;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity implements View.OnClickListener {

    //Declaration Button
    Button btnClickMe;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //Intialization Button

        btnClickMe = (Button) findViewById(R.id.btnClickMe);

        btnClickMe.setOnClickListener(MainActivity.this);
        //Here MainActivity.this is a Current Class Reference (context)
    }

    @Override
    public void onClick(View v) {

        //Your Logic
    }
}

As other people have commented, because the return type of your method is String Spring won't feel need to do anything with the result.

If you change your signature so that the return type is something that needs marshalling, that should help:

@RequestMapping(value = "/json", method = RequestMethod.GET, produces = "application/json")
@ResponseBody
public Map<String, Object> bar() {
    HashMap<String, Object> map = new HashMap<String, Object>();
    map.put("test", "jsonRestExample");
    return map;
}

It is possible but you should use EnumSet instead

enum MyEnum {
    ONE, TWO;
    public static final EnumSet<MyEnum> all = EnumSet.of(ONE, TWO);
}

In terms of networking and security, the Backend is by far the most (should be) secure node.

The middle-end portion, usually being a web server, will be somewhat in the wild and cut off in many respects from a company's network. The middle-end node is usually placed in the DMZ and segmented from the network with firewall settings. Most of the server-side code parsing of web pages is handled on the middle-end web server.

Getting to the backend means going through the middle-end, which has a carefully crafted set of rules allowing/disallowing access to the vital nummies which are stored on the database (backend) server.

You should consider using layer-list

Create a drawable file like this, name it as ic_calendar.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="rectangle">
        <solid android:color="@android:color/transparent"/>
    </shape>
</item>
<item android:right="10dp">
    <bitmap android:gravity="center_vertical|left"
        android:src="@drawable/ic_calendar_16dp"
        android:tint="@color/red"
        />
</item>
</layer-list>

Under layout file,

<TextView
         android:id="@+id/tvDate"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:drawableLeft="@drawable/ic_calendar"
         android:textColor="@color/colorGrey"
         android:textSize="14sp" 
    />

I've found my optimal blocksize to be 8 MB (equal to disk cache?) I needed to wipe (some say: wash) the empty space on a disk before creating a compressed image of it. I used:

cd /media/DiskToWash/
dd if=/dev/zero of=zero bs=8M; rm zero

I experimented with values from 4K to 100M.

After letting dd to run for a while I killed it (Ctlr+C) and read the output:

36+0 records in
36+0 records out
301989888 bytes (302 MB) copied, 15.8341 s, 19.1 MB/s

As dd displays the input/output rate (19.1MB/s in this case) it's easy to see if the value you've picked is performing better than the previous one or worse.

My scores:

bs=   I/O rate
---------------
4K    13.5 MB/s
64K   18.3 MB/s
8M    19.1 MB/s <--- winner!
10M   19.0 MB/s
20M   18.6 MB/s
100M  18.6 MB/s   

Note: To check what your disk cache/buffer size is, you can use sudo hdparm -i /dev/sda

I'd realise its a very old question, but since i wondered today for a more efficient method of handling the bootstrap modals. I did some research and found something better then the solutions which are shown above, that can be found at this link:

http://www.petefreitag.com/item/809.cfm

First load the jquery

$(document).ready(function() {
    $('a[data-confirm]').click(function(ev) {
        var href = $(this).attr('href');

        if (!$('#dataConfirmModal').length) {
            $('body').append('<div id="dataConfirmModal" class="modal" role="dialog" aria-labelledby="dataConfirmLabel" aria-hidden="true"><div class="modal-header"><button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button><h3 id="dataConfirmLabel">Please Confirm</h3></div><div class="modal-body"></div><div class="modal-footer"><button class="btn" data-dismiss="modal" aria-hidden="true">Cancel</button><a class="btn btn-primary" id="dataConfirmOK">OK</a></div></div>');
        } 
        $('#dataConfirmModal').find('.modal-body').text($(this).attr('data-confirm'));
        $('#dataConfirmOK').attr('href', href);
        $('#dataConfirmModal').modal({show:true});
        return false;
    });
});

Then just ask any question/confirmation to href:

<a href="/any/url/delete.php?ref=ID" data-confirm="Are you sure you want to delete?">Delete</a>

This way the confirmation modal is a lot more universal and so it can easily be re-used on other parts of your website.

sort sorts inplace so returns nothing:

In [54]:
df = pd.DataFrame({'A':[1,1,3,2,6,2,8]})
a = df['A'].unique()
a.sort()
a

Out[54]:
array([1, 2, 3, 6, 8], dtype=int64)

So you have to call print a again after the call to sort.

Eg.:

In [55]:
df = pd.DataFrame({'A':[1,1,3,2,6,2,8]})
a = df['A'].unique()
a.sort()
print(a)

[1 2 3 6 8]

I had the same issue trying to find text in files with powershell. I used the following - to stay as close to the Linux environment as possible.

Hopefully this helps somebody:

PowerShell:

PS) new-alias grep findstr
PS) ls -r *.txt | cat | grep "some random string"

Explanation:

ls       - lists all files
-r       - recursively (in all files and folders and subfolders)
*.txt    - only .txt files
|        - pipe the (ls) results to next command (cat)
cat      - show contents of files comming from (ls)
|        - pipe the (cat) results to next command (grep)
grep     - search contents from (cat) for "some random string" (alias to findstr)

Yes, this works as well:

PS) ls -r *.txt | cat | findstr "some random string"

There's no easy way to do this, but something like this will work:

SELECT ET.TrainingID, 
  ET.CompletedDate, 
  ET.Notes
FROM 
HR_EmployeeTrainings ET
inner join
(
  select TrainingID, Max(CompletedDate) as CompletedDate
  FROM HR_EmployeeTrainings
  WHERE (ET.AvantiRecID IS NULL OR ET.AvantiRecID = @avantiRecID)
  GROUP BY AvantiRecID, TrainingID  
) ET2 
  on ET.TrainingID = ET2.TrainingID
  and ET.CompletedDate = ET2.CompletedDate

Split the results of the date command by slash, then you can move each of the tokens into the appropriate variables.

FOR /F "tokens=1-3 delims=/" %%a IN ("%date:~4%") DO (
SET _Month=%%a
SET _Day=%%b
SET _Year=%%c
)
ECHO Month %_Month%
ECHO Day %_Day%
ECHO Year %_Year%

In my case, my dataframe has the following characteristics

<class 'pandas.core.frame.DataFrame'>
Index: 3040 entries, 15/12/2008 to  
Data columns (total 1 columns):
 #   Column  Non-Null Count  Dtype  
---  ------  --------------  -----  
 0   Close   3038 non-null   float64
dtypes: float64(1)
memory usage: 47.5+ KB

The first option data.index = pd.to_datetime(data.index) returned

ParserError: String does not contain a date: ParserError: String does not contain a date:

The second option: data.index.to_datetime() returned

AttributeError: 'Index' object has no attribute 'to_datetime'

It returned

Another option I have tested is. data.index = pd.to_datetime(data.index)

It returned: ParserError: String does not contain a date:

What could be my problem? Thanks

In my case, I was simply writing the fetch request URL wrong. On serverless.yml, you set cors to true:

register-downloadable-client:
    handler: fetch-downloadable-client-data/register.register
    events:
      - http:
          path: register-downloadable-client
          method: post
          integration: lambda
          cors: true
          stage: ${self:custom.stage}

and then on the lambda handler you send the headers, but if you make the fetch request wrong on the frontend, you're not going to get that header on the response and you're going to get this error. So, double check your request URL on the front.

Using angular 1.5.9

I made it working like this by setting the window.location to the csv file download url. Tested and its working with the latest version of Chrome and IE11.

Angular

   $scope.downloadStats = function downloadStats{
        var csvFileRoute = '/stats/download';
        $window.location = url;
    }

html

<a target="_self" ng-click="downloadStats()"><i class="fa fa-download"></i> CSV</a>

In php set the below headers for the response:

$headers = [
    'content-type'              => 'text/csv',
    'Content-Disposition'       => 'attachment; filename="export.csv"',
    'Cache-control'             => 'private, must-revalidate, post-check=0, pre-check=0',
    'Content-transfer-encoding' => 'binary',
    'Expires' => '0',
    'Pragma' => 'public',
];

I'm going to go against the grain here and state that the principle of separating content from layout (which would justify the answers that suggest using CSS) does not always apply to image height and width.

Each image has an innate, original height and width that can be derived from the image data. In the framework of content vs layout, I would say that this derived height and width information is content, not layout, and should therefore be rendered as HTML as element attributes.

This is much like the alt text, which can also be said to be derived from the image. This also supports the idea that an arbitrary user agent (e.g. a speech browser) should have that information in order to relate it to the user. At the least, the aspect ratio could prove useful ("image has a width of 15 and a height of 200"). Such user agents wouldn't necessarily process any CSS.

The spec says that the width and height attributes can also be used to override the height and width conveyed in the actual image file. I am not suggesting they be used for this. To override height and width, I believe CSS (inline, embedded or external) is the best approach.

So depending on what you want to do, you would specify one and/or the other. I think ideally, the original height and width would always be specified as HTML element attributes, while styling information should optionally be conveyed in CSS.

Best practice for RESTful API design is that path params are used to identify a specific resource or resources, while query parameters are used to sort/filter those resources.

Here's an example. Suppose you are implementing RESTful API endpoints for an entity called Car. You would structure your endpoints like this:

GET /cars
GET /cars/:id
POST /cars
PUT /cars/:id
DELETE /cars/:id

This way you are only using path parameters when you are specifying which resource to fetch, but this does not sort/filter the resources in any way.

Now suppose you wanted to add the capability to filter the cars by color in your GET requests. Because color is not a resource (it is a property of a resource), you could add a query parameter that does this. You would add that query parameter to your GET /cars request like this:

GET /cars?color=blue

This endpoint would be implemented so that only blue cars would be returned.

As far as syntax is concerned, your URL names should be all lowercase. If you have an entity name that is generally two words in English, you would use a hyphen to separate the words, not camel case.

Ex. /two-words

Natively it is overly complicated and messy to achieve this just with Bootstrap 3.4 Carousel and Bootstrap 4.5 Carousel javascript component features.

OK so you do not want yet another jQuery plugin... I get that.

In my opinion if you're already forced to use jQuery in your project, you might as well have a decent jQuery carousel plugin with lots powerful options.

slick.js - the last carousel you'll ever need - Ken Wheeler

         _ _      _       _
     ___| (_) ___| | __  (_)___
    / __| | |/ __| |/ /  | / __|
    \__ \ | | (__|   < _ | \__ \
    |___/_|_|\___|_|\_(_)/ |___/
                       |__/

It truly is the last jQuery carousel plugin you will ever need.

Here are minified slick.js distribution sizes...

• slick-carousel/1.9.0/slick.min.css - 1,369 bytes (4 KB on disk)
• slick-carousel/1.9.0/slick.min.js - 43,881 bytes (45 KB on disk)

Some scenarios you may be faced with...

• Unfortunately if you are just pulling distributed Bootstrap 3 or 4 js and css minified files from a CDN or where ever, then yeah it's another bulky jQuery plugin added to your website network requests.
• If you are using NPM, Gulp, Bower or whatever you can just exclude the carousel.js and carousel.scss to reduce the final compiled sizes of your css and js. Excluding all unused Bootstrap js and scss vendors will help reduced your final compiled outputs anyway.

Added bonuses using slick.js...

• Touch/swipe to scroll carousel on devices (you can drag on desktop too)
• Define carousel options for each responsive breakpoint
• Set mobileFirst: true or false to handle responsive breakpoint direction
• Set how many slides (columns) you wish to show or scroll (define for each breakpoint)
• Vertical and horizontal carousels
• .on events for everything
• Loads of options

I had the same issue because I was toggling my modal twice as shown below:

statusCode: {
    410: function (request, status, error) { //custom error code

        document.getElementById('modalbody').innerHTML = error;
        $('#myErrorModal').modal('toggle')
    }
},
error: function (request, error) {

    document.getElementById('modalbody').innerHTML = error;
    $('#myErrorModal').modal('toggle')
}

I removed one occurrence of:

$('#myErrorModal').modal('toggle')

and it worked like magic!

You could use iterator to do that:

For keys:

for (Iterator <tab> itr= hash.keySet().iterator(); itr.hasNext();) {
    // use itr.next() to get the key value
}

You can use iterator similarly with values.

In page header, add

<meta name="viewport" content="width=device-width, initial-scale=1, minimum-sacle=1, maximum-scale=1, user-scalable=no">

In page stylesheet, add

html, body {
  overflow-x: hidden;
  overflow-y: hidden;
}

It is both html and body!

In my case I've used this:

var query = "select * from table where Id IN @Ids";
var result = conn.Query<MyEntity>(query, new { Ids = ids });

my variable "ids" in the second line is an IEnumerable of strings, also they can be integers I guess.

In Debian Jessie, this works nice:

ls -lah --group-directories-first

# l=use a long listing format
# a=do not ignore entries starting with .
# h=human readable
# --group-directories-first=(obvious)
# Note: add -r for reverse alpha

# You might consider using lh by appending to ~/.bashrc as the alias:
~$ echo "alias lh='ls -lah --group-directories-first'" >>~/.bashrc
# -- restart your terminal before using lh command --

Have the same problem with white screen during transition from one fragment to another. Have navigation and animations set in action in navigation.xml.

Background in all fragments the same but white blank screen. So i set navOptions in fragment during executing transition

          //Transition options
        val options = navOptions {
            anim {
                enter = R.anim.slide_in_right
                exit = R.anim.slide_out_left
                popEnter = R.anim.slide_in_left
                popExit = R.anim.slide_out_right
            }
        }

.......................

  this.findNavController().navigate(SampleFragmentDirections.actionSampleFragmentToChartFragment(it),
                    options)

It worked for me. No white screen between transistion. Magic )

You can make it by one line:

mymap := map[string]interface{}{"foo": map[string]interface{}{"first": 1}, "boo": map[string]interface{}{"second": 2}}
for k, v := range mymap {
    fmt.Println("k:", k, "v:", v)
}

Output is:

k: foo v: map[first:1]
k: boo v: map[second:2]

When plotting a plot using matplotlib:

How to remove the box of the legend?

plt.legend(frameon=False)

How to change the color of the border of the legend box?

leg = plt.legend()
leg.get_frame().set_edgecolor('b')

How to remove only the border of the box of the legend?

leg = plt.legend()
leg.get_frame().set_linewidth(0.0)

Compare < and > just as usual, but anything involving = should use a + prefix. Like so:

var x = new Date('2013-05-23');
var y = new Date('2013-05-23');

// less than, greater than is fine:
x < y; => false
x > y; => false
x === y; => false, oops!

// anything involving '=' should use the '+' prefix
// it will then compare the dates' millisecond values
+x <= +y;  => true
+x >= +y;  => true
+x === +y; => true

You should put the form inside each node and use ng-show and ng-hide to enable and disable editing, respectively. Something like this:

<li>
  <span ng-hide="editing" ng-click="editing = true">{{bday.name}} | {{bday.date}}</span>
  <form ng-show="editing" ng-submit="editing = false">
    <label>Name:</label>
    <input type="text" ng-model="bday.name" placeholder="Name" ng-required/>
    <label>Date:</label>
    <input type="date" ng-model="bday.date" placeholder="Date" ng-required/>
    <br/>
    <button class="btn" type="submit">Save</button>
   </form>
 </li>

The key points here are:

• I've changed controls ng-model to the local scope
• Added ng-show to form so we can show it while editing
• Added a span with a ng-hide to hide the content while editing
• Added a ng-click, that could be in any other element, that toggles editing to true
• Changed ng-submit to toggle editing to false

Here is your updated Plunker.

Well, You can do it with mustache expression ({{Date.now() | date:'dd.MM.yyyy HH:mm:ss'}}). You just need to assign the Date object to scope where You want to evaluate this expression.

Here's jsfiddle example: jsfiddle

But don't expect it to update value automatically. This value is not watched by angular so You have to trigger digest every time You want to get it updated (by $interval for example)...which is waste of resources (and also not "recommended" in docs). Of course You can get to use of combination with directives/controllers to mess around with child scope only (it's always smaller than for example rootScope and digest will be quicker).

I tried to use more than two windows using the Rushy Panchal example above. The intent was to have the change to call more windows with different widgets in them. The butnew function creates different buttons to open different windows. You pass as argument the name of the class containing the window (the second argument is nt necessary, I put it there just to test a possible use. It could be interesting to inherit from another window the widgets in common.

import tkinter as tk

class Demo1:
    def __init__(self, master):
        self.master = master
        self.master.geometry("400x400")
        self.frame = tk.Frame(self.master)
        self.butnew("Window 1", "ONE", Demo2)
        self.butnew("Window 2", "TWO", Demo3)
        self.frame.pack()

    def butnew(self, text, number, _class):
        tk.Button(self.frame, text = text, width = 25, command = lambda: self.new_window(number, _class)).pack()

    def new_window(self, number, _class):
        self.newWindow = tk.Toplevel(self.master)
        _class(self.newWindow, number)

        self.label = tk.Label(master, text=f"this is window number {number}")
        self.label.pack()

Open the new window only once

To avoid having the chance to press multiple times the button having multiple windows... that are the same window, I made this script (take a look at this page too)

import tkinter as tk


def new_window1():
    global win1
    try:
        if win1.state() == "normal": win1.focus()
    except:
        win1 = tk.Toplevel()
        win1.geometry("300x300+500+200")
        win1["bg"] = "navy"
        lb = tk.Label(win1, text="Hello")
        lb.pack()


win = tk.Tk()
win.geometry("200x200+200+100")
button = tk.Button(win, text="Open new Window")
button['command'] = new_window1
button.pack()
win.mainloop()

Nested if's in Excel Are ugly:

=If(G2 < 1, .1, IF(G2 < 5,.15,if(G2 < 15,.2,if(G2 < 30,.5,if(G2 < 100,.1,1.3)))))

That should cover it.

You have to use a custom parsing string. I also suggest to include the invariant culture to identify that this format does not relate to any culture. Plus, it will prevent a warning in some code analysis tools.

var date = DateTime.ParseExact(value, "yyyyMMddHHmmss", CultureInfo.InvariantCulture);

I was having this issue. I was using XAMPP in a virtual machine which was having network setting as "NAT". I changed it to "Bridged" and the problem got solved.

You could use result = result.replaceAll("\n",""); or

 String[] split = result.split("\n");

You need to specify the source dir

File> Project Structure > Modules

click the directory and click the Sources button

It's weird because usually it's done automatically. Maybe it's better if you recreate the project again.

SASS (SCSS) triangle mixin

I wrote this to make it easier (and DRY) to automatically generate a CSS triangle:

// Triangle helper mixin (by Yair Even-Or)
// @param {Direction} $direction - either `top`, `right`, `bottom` or `left`
// @param {Color} $color [currentcolor] - Triangle color
// @param {Length} $size [1em] - Triangle size
@mixin triangle($direction, $color: currentcolor, $size: 1em) {
  $size: $size/2;
  $transparent: rgba($color, 0);
  $opposite: (top:bottom, right:left, left:right, bottom:top);

  content: '';
  display: inline-block;
  width: 0;
  height: 0;
  border: $size solid $transparent;
  border-#{map-get($opposite, $direction)}-color: $color;
  margin-#{$direction}: -$size;
}

use-case example:

span {
  @include triangle(bottom, red, 10px);
}

Playground page

Important note:
if the triangle seems pixelated in some browsers, try one of the methods described here.

I believe the best method with jQuery is using .scrollTop():

var pos = $('body').scrollTop();

I'm quite sure you won't get this 32Bit DLL working in Office 64Bit. The DLL needs to be updated by the author to be compatible with 64Bit versions of Office.

The code changes you have found and supplied in the question are used to convert calls to APIs that have already been rewritten for Office 64Bit. (Most Windows APIs have been updated.)

From: http://technet.microsoft.com/en-us/library/ee681792.aspx:

"ActiveX controls and add-in (COM) DLLs (dynamic link libraries) that were written for 32-bit Office will not work in a 64-bit process."

Edit: Further to your comment, I've tried the 64Bit DLL version on Win 8 64Bit with Office 2010 64Bit. Since you are using User Defined Functions called from the Excel worksheet you are not able to see the error thrown by Excel and just end up with the #VALUE returned.

If we create a custom procedure within VBA and try one of the DLL functions we see the exact error thrown. I tried a simple function of swe_day_of_week which just has a time as an input and I get the error Run-time error '48' File not found: swedll32.dll.

Now I have the 64Bit DLL you supplied in the correct locations so it should be found which suggests it has dependencies which cannot be located as per https://stackoverflow.com/a/8607250/1733206

I've got all the .NET frameworks installed which would be my first guess, so without further information from the author it might be difficult to find the problem.

Edit2: And after a bit more investigating it appears the 64Bit version you have supplied is actually a 32Bit version. Hence the error message on the 64Bit Office. You can check this by trying to access the '64Bit' version in Office 32Bit.

I think i know what you mean, if you want to send an array through a URL you can use serialize

for example:

$foo = array(1,2,3);
$serialized_array = serialize($foo);
$url = "http://www.foo.whatever/page.php?vars=".urlencode($serialized_array);

and on page.php

$vars = unserialize($_GET['vars']);

In my case I substitute it with utf8_general_ci with sed like this:

sed -i 's/utf8_0900_ai_ci/utf8_general_ci/g' MY_DB.sql 
sed -i 's/utf8mb4_unicode_520_ci/utf8_general_ci/g' MY_DB.sql 

After that, I can import it without any issue.

The posted code solutions may cause problems when you need to set up multiple SMTP sessions anywhere within the same JVM.

The JavaMail FAQ recommends using

Session.getInstance(properties);

instead of

Session.getDefaultInstance(properties);

because the getDefault will only use the properties given the first time it is invoked. All later uses of the default instance will ignore property changes.

See http://www.oracle.com/technetwork/java/faq-135477.html#getdefaultinstance

To add new ViewController once you have have an existing ViewController, follow below step:

1. Click on background of Main.storyboard.

2. Search and select ViewController from object library at the utility window.

3. Drag and drop it in background to create a new ViewController.

in my case it works i.e i want npm link so when I hit sudo npm link it works

sudo npm install

because sudo gives you permissions to superuser levels. superuser account is usually called 'Administrator.' In Linux/Unix the superuser account is generally named 'root'.

The root user has permission to access, modify or delete almost any file on your computer. Normal user accounts can access, modify or delete many fewer files. The restrictions on a normal account protect your computer from unauthorized or harmful programs or users.

Actually, for the latest JBOSS 7 AS, we need a .dodeploy marker even for archives. So add a marker to trigger the deployment.

In my case, I added a Hello.war.deployed file in the same directory and then everything worked fine.

Hope this helps someone!

For below code, xGen is an anonomous generator expression, yFilt is a filter object. Note that for xGen the additional None parameter is returned rather than throwing StopIteration when the list is exhausted.

arr =((10,0), (11,1), (12,2), (13,2), (14,3))

value = 2
xGen = (x for x in arr if x[1] == value)
yFilt = filter(lambda x: x[1] == value, arr)
print(type(xGen))
print(type(yFilt))

for i in range(1,4):
    print('xGen: pass=',i,' result=',next(xGen,None))
    print('yFilt: pass=',i,' result=',next(yFilt))

Output:

<class 'generator'>
<class 'filter'>
xGen: pass= 1  result= (12, 2)
yFilt: pass= 1  result= (12, 2)
xGen: pass= 2  result= (13, 2)
yFilt: pass= 2  result= (13, 2)
xGen: pass= 3  result= None
Traceback (most recent call last):
  File "test.py", line 12, in <module>
    print('yFilt: pass=',i,' result=',next(yFilt))
StopIteration

You can use unfocus() method from FocusNode class.

import 'package:flutter/material.dart';

class MyHomePage extends StatefulWidget {
  MyHomePageState createState() => new MyHomePageState();
}

class MyHomePageState extends State<MyHomePage> {
  TextEditingController _controller = new TextEditingController();
  FocusNode _focusNode = new FocusNode(); //1 - declare and initialize variable

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(),
      floatingActionButton: new FloatingActionButton(
        child: new Icon(Icons.send),
        onPressed: () {
            _focusNode.unfocus(); //3 - call this method here
        },
      ),
      body: new Container(
        alignment: FractionalOffset.center,
        padding: new EdgeInsets.all(20.0),
        child: new TextFormField(
          controller: _controller,
          focusNode: _focusNode, //2 - assign it to your TextFormField
          decoration: new InputDecoration(labelText: 'Example Text'),
        ),
      ),
    );
  }
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      home: new MyHomePage(),
    );
  }
}

void main() {
  runApp(new MyApp());
}

I too was looking for this for Facebook reasons and none of the answers given so far worked as needed or are too complicated.

@Request.Url.GetLeftPart(UriPartial.Path)

Gets the full protocol, host and path "without" the querystring. Also includes the port if you are using something other than the default 80.

If using MS Access (especially older versions like 2003) you are forced to use TEXT datatype on SQL Server as MS Access does not recognize nvarchar(MAX) as a Memo field in Access, whereas TEXT is recognized as a Memo-field.

I recommend you to read more about the this keyword.

You cannot expect "this" to select the "select" tag in this case.

What you want to do in this case is use obj.id to get the id of select tag.

You can do this

cat /dev/urandom|od -N2 -An -i|awk -v f=2000 -v r=65000 '{printf "%i\n", f + r * $1 / 65536}'

If you need more details see Shell Script Random Number Generator.

Just do the following change

echo off
cls

echo Would you like to do a backup?

pause

copy "\\My_Servers_IP\Shared Drive\FolderName\*" C:\TEST_BACKUP_FOLDER

pause

try this

 $('html').click(function() {
 //your stuf
 });

 $('#menucontainer').click(function(event){
     event.stopPropagation();
 });

you can also use the outside events

You inflate an XML resource. See the LayoutInflater doc .

If your layout is in a mylayout.xml, you would do something like:

View view; 
LayoutInflater inflater = (LayoutInflater)   getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
view = inflater.inflate(R.layout.mylayout, null);

RelativeLayout item = (RelativeLayout) view.findViewById(R.id.item);

If double backslash looks weird to you, C# also allows verbatim string literals where the escaping is not required.

Console.WriteLine(@"Mango \ Nightangle");

Don't you just wish Java had something like this ;-)

In my case after files with names containing those characters were uploaded, they were not even visible with Filezilla! In Cpanel filemanager they were shown with ? (under black background). And this combination made it shown correctly on the browser (HTML document is Western-encoded):

$dspFileName = utf8_decode(htmlspecialchars(iconv(mb_internal_encoding(), 'utf-8', basename($thisFile['path']))) );

ASP.NET spawns and kills worker processes all the time as needed. Your thread may just be getting shut down by ASP.NET.

Old Answer:

Try Date.now().

The skipping is most likely due to garbage collection. Typically garbage collection can be avoided by reusing variables as much as possible, but I can't say specifically what methods you can use to reduce garbage collection pauses.

We had the same issue with our Azure DevOps repositories after our domain changed, i.e. from @xy.com to @xyz.com. To fix this issue, we generated a fresh personal access token with the following permissions:

Code: read & write Packaging: read

Then we opened the Windows Credential Manager, added a new generic windows credential with the following details:

Internet or network address: "git:{projectname}@dev.azure.com/{projectname}" - alternatively you should use your git repository name here.
User name: "Personal Access Token"
Password: {The generated Personal Access Token}

Afterwards all our git operations were working again. Hope this helps someone else!

Assuming a simple case, where your field is public:

List list; // from your method
for(Object x : list) {
    Class<?> clazz = x.getClass();
    Field field = clazz.getField("fieldName"); //Note, this can throw an exception if the field doesn't exist.
    Object fieldValue = field.get(x);
}

But this is pretty ugly, and I left out all of the try-catches, and makes a number of assumptions (public field, reflection available, nice security manager).

If you can change your method to return a List<Foo>, this becomes very easy because the iterator then can give you type information:

List<Foo> list; //From your method
for(Foo foo:list) {
    Object fieldValue = foo.fieldName;
}

Or if you're consuming a Java 1.4 interface where generics aren't available, but you know the type of the objects that should be in the list...

List list;
for(Object x: list) {
   if( x instanceof Foo) {
      Object fieldValue = ((Foo)x).fieldName;
   }
}

No reflection needed :)

try putting both images next to each other. Like this:

Gmail: OAuth

• Goto the link
• Login with your gmail username password
• Click on the google menu at the top left
• Click API Manager
• Click on Credentials
• Click Create Credentials and select OAuth Client
• Select Web Application as Application type and Enter the Name-> Enter Authorised Redirect URL (Eg: http://localhost:53922/signin-google) ->Click on Create button. This will create the credentials. Pls make a note of Client ID and Secret ID. Finally click OK to close the credentials pop up.
• Next important step is to enable the Google API. Click on Overview in the left pane.
• Click on the Google API under Social APIs section.
• Click Enable.

That’s all from the Google part.

Come back to your application, open App_start/Startup.Auth.cs and uncomment the following snippet

        app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
        {
            ClientId = "",
            ClientSecret = ""
        });

Update the ClientId and ClientSecret with the values from Google API credentials which you have created already.

• Run your application
• Click Login
• You will see the Google button under ‘Use Another Section to log in’ section
• Click on the Google button
• Application will prompt you to enter the username and password
• Enter the gmail username and password and click Sign In
• This will perform the OAuth and come back to your application and prompting you to register with the Gmail id.
• Click register to register the Gmail id into your application database.
• You will see the Identity details appear in the top as normal registration
• Try logout and login again thru Gmail. This will automatically logs you into the app.

In simple words: You do abstraction when deciding what to implement. You do encapsulation when hiding something that you have implemented.

Like this

Vehicle[] car = new Vehicle[10];

The only way I know how is to do it individually, for example:

setenv CLASSPATH /User/username/newfolder/jarfile.jar:jarfile2.jar:jarfile3.jar:.

Hope that helps!

With regards to @CrazyJugglerDrummer second method it would be:

elementsToChange.style.cursor = "http://wiki-devel.sugarlabs.org/images/e/e2/Arrow.cur";

The Request object is the entire request sent out to some server. This object comes with a QueryString dictionary that is everything after '?' in the URL.

I stumbled upon this old listing pondering this same question. My band-aid for this same question was to make my header text into a link. I then changed the color and removed text decoration with CSS. Now to make the entire header picture a link, I expanded the padding of the anchor tag until it reached close to the edge of the header image.... This worked to my satisfaction, and I figured i would share.

First, you are strongly discouraged to do almost any cast, so you should limit it as much as possible! You lose the benefits of Java's compile-time strongly-typed features.

In any case, Class.cast() should be used mainly when you retrieve the Class token via reflection. It's more idiomatic to write

MyObject myObject = (MyObject) object

rather than

MyObject myObject = MyObject.class.cast(object)

EDIT: Errors at compile time

Over all, Java performs cast checks at run time only. However, the compiler can issue an error if it can prove that such casts can never succeed (e.g. cast a class to another class that's not a supertype and cast a final class type to class/interface that's not in its type hierarchy). Here since Foo and Bar are classes that aren't in each other hierarchy, the cast can never succeed.

String  input = EditTextinput.getText().toString();
input = input.replace(" ", "");

Sometimes you would want to remove only the spaces at the beginning or end of the String (not the ones in the middle). If that's the case you can use trim:

input = input.trim();

Using SXSSF poi 3.8

        SXSSFSheet sh = (SXSSFSheet) wb.getSheetAt(0);
        sh.setRandomAccessWindowSize(100);// keep 100 rows in memory, exceeding rows will be flushed to disk
    for(int rownum = 4; rownum < 100000; rownum++){
        Row row = sh.createRow(rownum);

I have a function next() which will maybe inspire you.

function queue(target) {
        var array = Array.prototype;

        var queueing = [];

        target.queue = queue;
        target.queued = queued;

        return target;

        function queued(action) {
            return function () {
                var self = this;
                var args = arguments;

                queue(function (next) {
                    action.apply(self, array.concat.apply(next, args));
                });
            };
        }

        function queue(action) {
            if (!action) {
                return;
            }

            queueing.push(action);

            if (queueing.length === 1) {

                if (err) {
                    throw err;
                }

                queueing = queueing.slice(1);

                if (queueing.length) {
                    next();

FWIW, I was able to setup a local RTSP server for testing purposes using simple-rtsp-server and ffmpeg following these steps:

1. Create a configuration file for the RTSP server called rtsp-simple-server.yml with this single line:

   protocols: [tcp]
   

2. Start the RTSP server as a Docker container:

   $ docker run --rm -it -v $PWD/rtsp-simple-server.yml:/rtsp-simple-server.yml -p 8554:8554 aler9/rtsp-simple-server
   

3. Use ffmpeg to stream a video file (looping forever) to the server:

   $ ffmpeg -re -stream_loop -1 -i test.mp4 -f rtsp -rtsp_transport tcp rtsp://localhost:8554/live.stream
   

Once you have that running you can use ffplay to view the stream:

$ ffplay -rtsp_transport tcp rtsp://localhost:8554/live.stream

Note that simple-rtsp-server can also handle UDP streams (i.s.o. TCP) but that's tricky running the server as a Docker container.

f = open('words.txt')

You can use splash screen in your first loading Activity like this:

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);

        Thread welcomeThread = new Thread() {

            @Override
            public void run() {
                try {
                    super.run();
                    sleep(10000);  //Delay of 10 seconds
                } catch (Exception e) {

                } finally {

                    Intent i = new Intent(SplashActivity.this,
                            MainActivity.class);
                    startActivity(i);
                    finish();
                }
            }
        };
        welcomeThread.start();
    }

Hope this code helps you.

This error can also occur if you are not following the marco rules

Like

#define 1K 1024 // Macro rules must be identifiers error occurs

Reason: Macro Should begin with a letter, not a number

Change to

#define ONE_KILOBYTE 1024 // This resolves 

Can also use

@(time(nil)).stringValue);

for timestamp in seconds.

If you want the placeholder text to be red you need to target it specifically in CSS.

Write:

If you want the algorithms to be implemented specifically in Java then there is Mitchell Waite's Series book "Data Structures & Algorithms in Java". It starts from basic data structures like linked lists, stacks and queues, and the basic algorithms for sorting and searching. Working your way through it you will eventually get to Tree data structures, Red-Black trees, 2-3 trees and Graphs.

All-in-all its not an extremely theoretical book, but if you just want an introduction in a language you are familiar with then its a good book. At the end of the day, if you want a deeper understanding of algorithms you're going to have to learn some of the more theoretical concepts, and read one of the classics, like Cormen/Leiserson/Rivest/Stein's Introduction to Algorithms.

The original example returns an error because the array is created empty, then you try to access the nth element to assign it a value.

The are a number of creative answers here, many I didn't know before reading this post. All are fine for a small array, but as n0rd points out, there are significant differences in performance.

Here I use Measure-Command to find out how long each initialization takes. As you might guess, any approach that uses an explicit PowerShell loop is slower than those that use .Net constructors or PowerShell operators (which would be compiled in IL or native code).

Summary

• New-Object and @(somevalue)*n are fast (around 20k ticks for 100k elements).
• Creating an array with the range operator n..m is 10x slower (200k ticks).
• Using an ArrayList with the Add() method is 1000x slower than the baseline (20M ticks), as is looping through an already-sized array using for() or ForEach-Object (a.k.a. foreach,%).
• Appending with += is the worst (2M ticks for just 1000 elements).

Overall, I'd say array*n is "best" because:

• It's fast.
• You can use any value, not just the default for the type.
• You can create repeating values (to illustrate, type this at the powershell prompt: (1..10)*10 -join " " or ('one',2,3)*3)
• Terse syntax.

The only drawback:

• Non-obvious. If you haven't seen this construct before, it's not apparent what it does.

But keep in mind that for many cases where you would want to initialize the array elements to some value, then a strongly-typed array is exactly what you need. If you're initializing everything to $false, then is the array ever going to hold anything other than $false or $true? If not, then New-Object type[] n is the "best" approach.

Testing

Create and size a default array, then assign values:

PS> Measure-Command -Expression {$a = new-object object[] 100000} | Format-List -Property "Ticks"
Ticks : 20039

PS> Measure-Command -Expression {for($i=0; $i -lt $a.Length;$i++) {$a[$i] = $false}} | Format-List -Property "Ticks"
Ticks : 28866028

Creating an array of Boolean is bit little slower than and array of Object:

PS> Measure-Command -Expression {$a = New-Object bool[] 100000} | Format-List -Property "Ticks"
Ticks : 130968

It's not obvious what this does, the documentation for New-Object just says that the second parameter is an argument list which is passed to the .Net object constructor. In the case of arrays, the parameter evidently is the desired size.

Appending with +=

PS> $a=@()
PS> Measure-Command -Expression { for ($i=0; $i -lt 100000; $i++) {$a+=$false} } | Format-List -Property "Ticks"

I got tired of waiting for that to complete, so ctrl+c then:

PS> $a=@()
PS> Measure-Command -Expression { for ($i=0; $i -lt    100; $i++) {$a+=$false} } | Format-List -Property "Ticks"
Ticks : 147663
PS> $a=@()
PS> Measure-Command -Expression { for ($i=0; $i -lt   1000; $i++) {$a+=$false} } | Format-List -Property "Ticks"
Ticks : 2194398

Just as (6 * 3) is conceptually similar to (6 + 6 + 6), so ($somearray * 3) ought to give the same result as ($somearray + $somearray + $somearray). But with arrays, + is concatenation rather than addition.

If $array+=$element is slow, you might expect $array*$n to also be slow, but it's not:

PS> Measure-Command -Expression { $a = @($false) * 100000 } | Format-List -Property "Ticks"
Ticks : 20131

Just like Java has a StringBuilder class to avoid creating multiple objects when appending, so it seems PowerShell has an ArrayList.

PS> $al = New-Object System.Collections.ArrayList
PS> Measure-Command -Expression { for($i=0; $i -lt 1000; $i++) {$al.Add($false)} } | Format-List -Property "Ticks"
Ticks : 447133
PS> $al = New-Object System.Collections.ArrayList
PS> Measure-Command -Expression { for($i=0; $i -lt 10000; $i++) {$al.Add($false)} } | Format-List -Property "Ticks"
Ticks : 2097498
PS> $al = New-Object System.Collections.ArrayList
PS> Measure-Command -Expression { for($i=0; $i -lt 100000; $i++) {$al.Add($false)} } | Format-List -Property "Ticks"
Ticks : 19866894

Range operator, and Where-Object loop:

PS> Measure-Command -Expression { $a = 1..100000 } | Format-List -Property "Ticks"
Ticks : 239863
Measure-Command -Expression { $a | % {$false} } | Format-List -Property "Ticks"
Ticks : 102298091

Notes:

• I nulled the variable between each run ($a=$null).
• Testing was on a tablet with Atom processor; you would probably see faster speeds on other machines. [edit: About twice as fast on a desktop machine.]
• There was a fair bit of variation when I tried multiple runs. Look for the orders of magnitude rather than exact numbers.
• Testing was with PowerShell 3.0 in Windows 8.

Thanks to @halr9000 for array*n, @Scott Saad and Lee Desmond for New-Object, and @EBGreen for ArrayList.

Thanks to @n0rd for getting me to think about performance.

$('#someid').attr('disabled', 'true');

One way to handle this is to put the information as an attribute on the primary one. I must stress, I really think this is the appropriate thing to do only when the two pieces of information are related such that one has information about the other.

For example, I sometimes stash the name of "crucial variables" or variables that have been significantly modified by storing a list of variable names as an attribute on the data frame:

attr(my.DF, 'Modified.Variables') <- DVs.For.Analysis$Names.of.Modified.Vars
return(my.DF)

This allows me to store a list of variable names with the data frame itself.

For anyone trying to use jQuery.active with JSONP requests (like I was) you'll need enable it with this:

jQuery.ajaxPrefilter(function( options ) {
    options.global = true;
});

Keep in mind that you'll need a timeout on your JSONP request to catch failures.

The equivalent is:

python3 -m http.server

For me (I'm using mac with terminal) only worked when I added on .bash_profile and opened another tab to load the change:

alias gst="git status"
alias gd="git diff"
alias gl="git log"
alias gco="git commit"
alias gck="git checkout"
alias gl="git pull"
alias gpom="git pull origin master"
alias gp="git push"
alias gb="git branch"

It is very simple, just do this:

t4.setOnClickListener(new OnClickListener(){

        @Override
        public void onClick(View v) {

            launchQuiz2();          // TODO Auto-generated method stub

        }

        private void launchQuiz2() {
            Intent i = new Intent(MainActivity.this, Quiz2.class);
            startActivity(i);
            // TODO Auto-generated method stub

        }

    });

[DataType(DataType.Date)]
public DateTime BirthDate { get; set; }

decorate your model like this. can use a bootstrap date time picker I used this one. https://github.com/Eonasdan/bootstrap-datetimepicker/

I suppose you already have bundles for bootstrap css and js

Your date picker bundle entries

 bundles.Add(new ScriptBundle("~/bundles/datePicker").Include(
           "~/Scripts/moment.min.js",
           "~/Scripts/bootstrap-datetimepicker.min.js"));

        bundles.Add(new StyleBundle("~/Content/datepicker").Include(
                 "~/Content/bootstrap-datetimepicker.min.css"));

Render bundles on your Layout View

@Styles.Render("~/Content/datepicker")
@Scripts.Render("~/bundles/datePicker")

Your HTML in view

<div class="form-group">
        @Html.LabelFor(model => model.BirthDate, htmlAttributes: new { @class = "lead col-md-2" })
        <div class="col-md-10">
            @Html.TextBoxFor(model => model.BirthDate, new { @class = "datetimepicker form-control" })
            @Html.ValidationMessageFor(model => model.BirthDate, "", new { @class = "text-danger" })
        </div>
</div>

At the end of your view add this.

<script>
    $(document).ready(function () {
        $('.datetimepicker').datetimepicker({
            format: 'lll'
        });
    });
</script>

Even I faced similar issues. This is how I was able to solve the same

    $("#lnkDetails").live('click', function (e) {

        //Create dynamic element after the element that raised the event. In my case a <a id="lnkDetails" href="/Attendance/Details/2012-07-01" />
        $(this).after('<div id=\"dialog-confirm\" />');

        //Optional : Load data from an external URL. The attr('href') is the href of the <a> tag.
        $('#dialog-confirm').load($(this).attr('href'));

        //Copied from jQueryUI site . Do we need this?
        $("#dialog:ui-dialog").dialog("destroy");

        //Transform the dynamic DOM element into a dialog
        $('#dialog-confirm').dialog({
            modal: true,
            title: 'Details'
        });

        //Prevent Bubbling up to other elements.
        return false;
    });

Async:

fs.readFile('test.txt', 'utf8', callback);

Sync:

var content = fs.readFileSync('test.txt', 'utf8');

You may use this command for listing the files for your own debuggable apk:

adb shell run-as com.corp.appName ls /data/data/com.corp.appName/cache

And this script for pulling from cache:

#!/bin/sh
adb shell "run-as com.corp.appName cat '/data/data/com.corp.appNamepp/$1' > '/sdcard/$1'"
adb pull "/sdcard/$1"
adb shell "rm '/sdcard/$1'"

Then you can pull a file from cache like this:

./pull.sh cache/someCachedData.txt

Root is not required.

One simple thing you could do is abstract the test inside a function.

local function isempty(s)
  return s == nil or s == ''
end

if isempty(foo) then
  foo = "default value"
end

I found the answer, thanks to your information Michelle. You can indeed get the right view using View#getChildAt(int index). The catch is that it starts counting from the first visible item. In fact, you can only get the visible items. You solve this with ListView#getFirstVisiblePosition().

Example:

private void updateView(int index){
    View v = yourListView.getChildAt(index - 
        yourListView.getFirstVisiblePosition());

    if(v == null)
       return;

    TextView someText = (TextView) v.findViewById(R.id.sometextview);
    someText.setText("Hi! I updated you manually!");
}

If you didn't have built-in filter or didn't want to use extra space and you need a linear solution...

def remove_all(A, v):
    k = 0
    n = len(A)
    for i in range(n):
        if A[i] !=  v:
            A[k] = A[i]
            k += 1

    A = A[:k]

Append a class containing pointer-events:non

.active a{ //css
text-decoration: underline;
background-color: #fff;
pointer-events: none;}


$(this).addClass('active');

You CAN use UTF-8 in the POST request, all you need is to specify the charset in your request.

You should use this request:

curl -X POST -H "Content-Type: application/x-www-form-urlencoded; charset=utf-8" --data-ascii "content=derinhält&date=asdf" http://myserverurl.com/api/v1/somemethod

While it is not possible to write a switch statement, it is possible to branch out to specific processing for each given type. One way of doing this is to use standard double dispatch mechanism. An example where we want to "switch" based on type is Jersey Exception mapper where we need to map multitude of exceptions to error responses. While for this specific case there is probably a better way (i.e. using a polymorphic method that translates each exception to an error response), using double dispatch mechanism is still useful and practical.

interface Processable {
    <R> R process(final Processor<R> processor);
}

interface Processor<R> {
    R process(final A a);
    R process(final B b);
    R process(final C c);
    // for each type of Processable
    ...
}

class A implements Processable {
    // other class logic here

    <R> R process(final Processor<R> processor){
        return processor.process(this);
    }
}

class B implements Processable {
    // other class logic here

    <R> R process(final Processor<R> processor){
        return processor.process(this);
    }
}

class C implements Processable {
    // other class logic here

    <R> R process(final Processor<R> processor){
        return processor.process(this);
    }
}

Then where ever the "switch" is needed, you can do it as follows:

public class LogProcessor implements Processor<String> {
    private static final Logger log = Logger.for(LogProcessor.class);

    public void logIt(final Processable base) {
        log.info("Logging for type {}", process(base));
    }

    // Processor methods, these are basically the effective "case" statements
    String process(final A a) {
        return "Stringifying A";
    }

    String process(final B b) {
        return "Stringifying B";
    }

    String process(final C c) {
        return "Stringifying C";
    }
}

Operator precedence in python
You can see that not X has higher precedence than and. Which means that the not only apply to the first part (u0 <= u). Write:

if not (u0 <= u and u < u0+step):  

or even

if not (u0 <= u < u0+step):  

First, set height greater than width. In theory, this is all you should need. The HTML5 Spec suggests as much:

... the UA determined the orientation of the control from the ratio of the style-sheet-specified height and width properties.

Opera had it implemented this way, but Opera is now using WebKit Blink. As of today, no browser implements a vertical slider based solely on height being greater than width.

Regardless, setting height greater than width is needed to get the layout right between browsers. Applying left and right padding will also help with layout and positioning.

For Chrome, use -webkit-appearance: slider-vertical.

For IE, use writing-mode: bt-lr.

For Firefox, add an orient="vertical" attribute to the html. Pity that they did it this way. Visual styles should be controlled via CSS, not HTML.

input[type=range][orient=vertical]
{
    writing-mode: bt-lr; /* IE */
    -webkit-appearance: slider-vertical; /* WebKit */
    width: 8px;
    height: 175px;
    padding: 0 5px;
}

<input type="range" orient="vertical" />

Disclaimers:

This solution is based on current browser implementations of as yet undefined or unfinalized CSS properties. If you intend to use it in your code, be prepared to make code adjustments as newer browser versions are released and w3c recommendations are completed.

MDN contains an explicit warning against using -webkit-appearance on the web:

Do not use this property on Web sites: not only is it non-standard, but its behavior change from one browser to another. Even the keyword none has not the same behavior on each form element on different browsers, and some doesn't support it at all.

The caption for the vertical slider demo in the IE documentation erroneously indicates that setting height greater than width will display a range slider vertically, but this does not work. In the code section, it plainly does not set height or width, and instead uses writing-mode. The writing-mode property, as implemented by IE, is very robust. Sadly, the values defined in the current working draft of the spec as of this writing, are much more limited. Should future versions of IE drop support of bt-lr in favor of the currently proposed vertical-lr (which would be the equivalent of tb-lr), the slider would display upside down. Most likely, future versions would extend the writing-mode to accept new values rather than drop support for existing values. But, it's good to know what you are dealing with.

There are 3 different ways you may wish to set this up:

1. Thrower inside of Catcher
2. Catcher inside of Thrower
3. Thrower and Catcher inside of another class in this example Test

THE WORKING GITHUB EXAMPLE I AM CITING Defaults to Option 3, to try the others simply uncomment the "Optional" code block of the class you want to be main, and set that class as the ${Main-Class} variable in the build.xml file:

4 Things needed on throwing side code:

import java.util.*;//import of java.util.event

//Declaration of the event's interface type, OR import of the interface,
//OR declared somewhere else in the package
interface ThrowListener {
    public void Catch();
}
/*_____________________________________________________________*/class Thrower {
//list of catchers & corresponding function to add/remove them in the list
    List<ThrowListener> listeners = new ArrayList<ThrowListener>();
    public void addThrowListener(ThrowListener toAdd){ listeners.add(toAdd); }
    //Set of functions that Throw Events.
        public void Throw(){ for (ThrowListener hl : listeners) hl.Catch();
            System.out.println("Something thrown");
        }
////Optional: 2 things to send events to a class that is a member of the current class
. . . go to github link to see this code . . .
}

2 Things needed in a class file to receive events from a class

/*_______________________________________________________________*/class Catcher
implements ThrowListener {//implement added to class
//Set of @Override functions that Catch Events
    @Override public void Catch() {
        System.out.println("I caught something!!");
    }
////Optional: 2 things to receive events from a class that is a member of the current class
. . . go to github link to see this code . . .
}

Note: This code is untested

Define a record for your refCursor return type, call it rec. For example:

TYPE MyRec IS RECORD (col1 VARCHAR2(10), col2 VARCHAR2(20), ...);  --define the record
rec MyRec;        -- instantiate the record

Once you have the refcursor returned from your procedure, you can add the following code where your comments are now:

LOOP
  FETCH refCursor INTO rec;
  EXIT WHEN refCursor%NOTFOUND;
  dbms_output.put_line(rec.col1||','||rec.col2||','||...);
END LOOP;

as noted earlier, setting bash variables does not allow whitespace between the variable name on the LHS, and the variable value on the RHS, of the '=' sign.

awk can do everything and avoid the "awk"ward extra 'grep'. The use of awk's printf is to not add an unnecessary "\n" in the string which would give perl-ish matcher programs conniptions. The variable/parameter expansion for your case in bash doesn't have that issue, so either of these work:

variable=$(ps -ef | awk '/port 10 \-/ {print $12}')

variable=`ps -ef | awk '/port 10 \-/ {print $12}'`

The '-' int the awk record matching pattern removes the need to remove awk itself from the search results.

Everyone has their personal favorite, and this is mine:

RUN useradd --user-group --system --create-home --no-log-init app
USER app

Reference: man useradd

The RUN line will add the user and group app:

root@ef3e54b60048:/# id app
uid=999(app) gid=999(app) groups=999(app)

Use a more specific name than app if the image is to be reused as a base image. As an aside, include --shell /bin/bash if you really need.

You have to specify the name of the custom view and its related model in Controller Action method.

public ActionResult About()
{            
   return View("NameOfViewYouWantToReturn",Model); 
}

Since you don't explicitly invoke a parent constructor as part of your child class constructor, there is an implicit call to a parameterless parent constructor inserted. That constructor does not exist, and so you get that error.

To correct the situation, you need to add an explicit call:

public Child(int i) : base(i)
{
    Console.WriteLine("child");
}

Or, you can just add a parameterless parent constructor:

protected Parent() { } 

Further to aduchis answer above - if you then need to filter based on those group by keys, you can define a class to wrap the many keys.

return customers.GroupBy(a => new CustomerGroupingKey(a.Country, a.Gender))
                .Where(a => a.Key.Country == "Ireland" && a.Key.Gender == "M")
                .SelectMany(a => a)
                .ToList();

Where CustomerGroupingKey takes the group keys:

    private class CustomerGroupingKey
    {
        public CustomerGroupingKey(string country, string gender)
        {
            Country = country;
            Gender = gender;
        }

        public string Country { get; }

        public string Gender { get; }
    }

suppose supply_master is a table, and

SQL>desc supply_master;


SQL>Name
 SUPPLIER_NO    
 SUPPLIER_NAME
 ADDRESS1       
 ADDRESS2       
 CITY           
 STATE          
 PINCODE  


SQL>alter table Supply_master rename column ADDRESS1 TO ADDR;
Table altered



SQL> desc Supply_master;
 Name                   
 -----------------------
 SUPPLIER_NO            
 SUPPLIER_NAME          
 ADDR   ///////////this has been renamed........//////////////                
 ADDRESS2               
 CITY                   
 STATE                  
 PINCODE                  

Most of the answers are working fine. We can also check the request header

request()->header('Accept')=='application/json'

to check the request type

PHP Manual said :

w Numeric representation of the day of the week

You can therefore construct a date with mktime, and use in it date("w", $yourTime);

I was recently able to accomplish this in MVC (although there was no need to use AJAX) without creating a physical file and thought I'd share my code:

Super simple JavaScript function (datatables.net button click triggers this):

function getWinnersExcel(drawingId) {
    window.location = "/drawing/drawingwinnersexcel?drawingid=" + drawingId;
}

C# Controller code:

    public FileResult DrawingWinnersExcel(int drawingId)
    {
        MemoryStream stream = new MemoryStream(); // cleaned up automatically by MVC
        List<DrawingWinner> winnerList = DrawingDataAccess.GetWinners(drawingId); // simple entity framework-based data retrieval
        ExportHelper.GetWinnersAsExcelMemoryStream(stream, winnerList, drawingId);

        string suggestedFilename = string.Format("Drawing_{0}_Winners.xlsx", drawingId);
        return File(stream, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet.main+xml", suggestedFilename);
    }

In the ExportHelper class I do use a 3rd party tool (GemBox.Spreadsheet) to generate the Excel file and it has a Save to Stream option. That being said, there are a number of ways to create Excel files that can easily be written to a memory stream.

public static class ExportHelper
{
    internal static void GetWinnersAsExcelMemoryStream(MemoryStream stream, List<DrawingWinner> winnerList, int drawingId)
    {

        ExcelFile ef = new ExcelFile();

        // lots of excel worksheet building/formatting code here ...

        ef.SaveXlsx(stream);
        stream.Position = 0; // reset for future read

     }
}

In IE, Chrome, and Firefox, the browser prompts to download the file and no actual navigation occurs.

Why not using just one controller action?

public string Get(int? id, string firstName, string lastName, string address)
{
   if (id.HasValue)
      GetById(id);
   else if (string.IsNullOrEmpty(address))
      GetByName(firstName, lastName);
   else
      GetByNameAddress(firstName, lastName, address);
}

Another option is to use attribute routing, but then you'd need to have a different URL format:

//api/person/byId?id=1
[HttpGet("byId")] 
public string Get(int id)
{
}

//api/person/byName?firstName=a&lastName=b
[HttpGet("byName")]
public string Get(string firstName, string lastName, string address)
{
}

I had a similar problem. I was attempting to have a file written every time a user visits a website.

The problem ended up being twofold.

1: the permissions were not set correctly

2: I attempted to use
f = open(r"newfile.txt","w+") (Wrong)

After changing the file to 777 (all users can read/write)
chmod 777 /var/www/path/to/file
and changing the path to an absolute path, my problem was solved
f = open(r"/var/www/path/to/file/newfile.txt","w+") (Right)

Swift 4.0

self.messageLabel = UILabel(frame: CGRect(x: 70, y: 60, width:UIScreen.main.bounds.width - 80, height: 30)

messageLabel.text = message

messageLabel.lineBreakMode = .byWordWrapping //in versions below swift 3 (messageLabel.lineBreakMode = NSLineBreakMode.ByWordWrapping)    
messageLabel.numberOfLines = 0 //To write any number of lines within a label scope

messageLabel.textAlignment = .center

messageLabel.textColor = UIColor.white

messageLabel.font = messageLabel.font.withSize(12)

messageLabel.sizeToFit()

Blockquote NSParagraphStyle.LineBreakMode, apply to entire paragraphs, not words within paragraphs.This property is in effect both during normal drawing and in cases where the font size must be reduced to fit the label’s text in its bounding box. This property is set to byTruncatingTail by default.

This link describes the storyboard way of doing the same

You could do something like this:

public System.Collections.IEnumerable GetDogsWithBreedNames()
{
    var db = new DogDataContext(ConnectString);
    var result = from d in db.Dogs
                 join b in db.Breeds on d.BreedId equals b.BreedId
                 select new
                        {
                            Name = d.Name,
                            BreedName = b.BreedName
                        };
    return result.ToList();
}

DSO here means Dynamic Shared Object; since the error message says it's missing from the command line, I guess you have to add it to the command line.

That is, try adding -lpthread to your command line.

Using numpy (highly recommended), you would do:

from numpy import (array, dot, arccos, clip)
from numpy.linalg import norm

u = array([1.,2,3,4])
v = ...
c = dot(u,v)/norm(u)/norm(v) # -> cosine of the angle
angle = arccos(clip(c, -1, 1)) # if you really want the angle

upper-case(string) and lower-case(string)

You can use this way to format your currency needing.

var xx = new Intl.NumberFormat(‘en-US’, {
  style: ‘currency’,
  currency: ‘USD’,
  minimumFractionDigits: 2,
  maximumFractionDigits: 2
});
xx.format(123456.789); // ‘$123,456.79’

You can go for identifying a list of elements with xPath:

//td[text() = ' Color Digest ']/following-sibling::td[1]

This will give you a list of two elements, than you can use the 2nd element as your intended one. For example:

List<WebElement> elements = driver.findElements(By.xpath("//td[text() = ' Color Digest ']/following-sibling::td[1]"))

Now, you can use the 2nd element as your intended element, which is elements.get(1)

Have you tried to use the "CSVIMPORT" function found in the file exchange? I haven't tried it myself, but it claims to handle all combinations of text and numbers.

http://www.mathworks.com/matlabcentral/fileexchange/23573-csvimport

Thank you WiredPrairie!

Just to expand on your answer a bit, here is a complete example of defining a constants class.

// CYConstants.ts

class CYConstants {
    public static get NOT_FOUND(): number    { return -1; }
    public static get EMPTY_STRING(): string { return ""; }
}

export = CYConstants;

To use

// main.ts

import CYConstants = require("./CYConstants");

console.log(CYConstants.NOT_FOUND);    // Prints -1
console.log(CYConstants.EMPTY_STRING); // Prints "" (Nothing!)

All answers above are awesome

Also add this otherwise your app will crash like mine without any reason

To remotely capture http or https traffic with charles you will need to do the following:

HOST - Machine running Charles and hosting the proxy CLIENT – User’s machine generating the traffic you will capture

Host Machine

1. Install fully licensed charles version
2. Proxy -> Proxy Settings -> check “Enable Transparent HTTP Proxying”
3. Proxy -> SSL Proxying Settings -> check “enable SSL Proxying”
4. Proxy -> SSL Proxying Settings -> click Add button and input * in both fields
5. Proxy -> Access Control Settings -> Add your local subnet (ex: 192.168.2.0/24) to authorize all machines on your local network to use the proxy from another machine
6. It might be advisable to set up the “auto save tool” in charles, this will auto save and rotate the charles logs.

Client Machine:

1. Install and permanently accept/trust the charles SSL certificate
   http://www.charlesproxy.com/documentation/using-charles/ssl-certificates/
2. Configure IE, Firefox, and Chrome to use the socket charles is hosting the proxy on (ex: 192.168.1.100:8888)

When I tested this out I picked up two lines of a Facebook HTTPS chat (one was a line TO someone, and the other FROM)

you can also capture android emulator traffic this way if you start the emulator with:

emulator -avd <avd name> -http-proxy http://local_ip:8888/

Where LOCAL_IP is the IP address of your computer, not 127.0.0.1 as that is the IP address of the emulated phone.

Source: http://brakertech.com/capture-https-traffic-remotely-with-charles/

none of the above answers worked for me. This one did:

=QUERY(Copy!A1:AP, "select AP, E, F, AO where AP="&E1&" ",1)

In the case of integers that are included at the string, if you want to avoid casting them to int individually you can do:

mList = [int(e) if e.isdigit() else e for e in mStr.split(',')]

It is called list comprehension, and it is based on set builder notation.

ex:

>>> mStr = "1,A,B,3,4"
>>> mList = [int(e) if e.isdigit() else e for e in mStr.split(',')]
>>> mList
>>> [1,'A','B',3,4]

Your problem is that your insertAfter:

.insertAfter(".tr_clone")

inserts after every .tr_clone:

the matched set of elements will be inserted after the element(s) specified by this parameter.

You probably just want to use after on the row you're duplicating. And a little .find(':text').val('') will clear the cloned text inputs; something like this:

var $tr    = $(this).closest('.tr_clone');
var $clone = $tr.clone();
$clone.find(':text').val('');
$tr.after($clone);

Demo: http://jsfiddle.net/ambiguous/LAECx/ or for a modern jQuery: http://jsfiddle.net/ambiguous/LAECx/3274/

I'm not sure which input should end up with the focus so I've left that alone.
