It looks like this is the case when Chrome is not compliant with WebSocket standard. When the server initiates close and sends close frame to a client, Chrome considers this to be an error and reports it to JS side with code 1006 and no reason message. In my tests, Chrome never responds to server-initiated close frames (close code 1000) suggesting that code 1006 probably means that Chrome is reporting its own internal error.

P.S. Firefox v57.00 handles this case properly and successfully delivers server's reason message to JS side.

The simplest way to remove duplicates whilst preserving order is to use collections.OrderedDict (Python 2.7+).

from collections import OrderedDict
d = OrderedDict()
for x in mylist:
    d[x] = True
print d.iterkeys()

HTML:

<div class="container">
    <span>
        <img ... >
    </span>
    <span>
        <img ... >
    </span>
    <span>
        <img ... >
    </span>
</div>

CSS:

.container{ width:50%; margin:0 auto; text-align:center}
.container span{ width:30%; margin:0 1%;  }

I haven't tested this, but hope this will work.

You can add 'display:inline-block' to .container span to make the span to have fixed 30% width

Because tuple(3, 4) is not the correct syntax to create a tuple. The correct syntax is -

tuple([3, 4])

or

(3, 4)

You can see it from here - https://docs.python.org/2/library/functions.html#tuple

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

Warning: Don't do this if you've already pushed

You want to do:

git reset HEAD~

If you don't want the changes and blow everything away:

git reset --hard HEAD~

When we use == , the Reference of object is compared not the actual objects. We need to override equals method to compare Java Objects.

Some additional information C++ has operator over loading & Java does not provide operator over loading. Also other possibilities in java are implement Compare Interface .which defines a compareTo method.

Comparator interface is also used compare two objects

$ pip install -U requests[security]

• Tested on Python 2.7.6 @ Ubuntu 14.04.4 LTS
• Tested on Python 2.7.5 @ MacOSX 10.9.5 (Mavericks)

When this question was opened (2012-05) the Requests version was 0.13.1. On version 2.4.1 (2014-09) the "security" extras were introduced, using certifi package if available.

Right now (2016-09) the main version is 2.11.1, that works good without verify=False. No need to use requests.get(url, verify=False), if installed with requests[security] extras.

Binding to 0.0.0.0 is half the battle. There is an ip firewall (different from the one in system preferences) that blocks TCP ports. Hence port must be unblocked there as well by doing:

sudo ipfw add <PORT NUMBER> allow tcp from any to any

That can be caused by unicode or other charset mismatch. Try changing charset in your browser, in of the settings the text will look OK. Then it's question of how to convert your database contents to charset you use for displaying. (Which can actually be just adding utf-8 charset statement to your output.)

You have to select the sheet before you can select the range.

I've simplified the example to isolate the problem. Try this:

Option Explicit


Sub RangeError()

    Dim sourceBook As Workbook
    Dim sourceSheet As Worksheet
    Dim sourceSheetSum As Worksheet

    Set sourceBook = ActiveWorkbook
    Set sourceSheet = sourceBook.Sheets("Sheet1")
    Set sourceSheetSum = sourceBook.Sheets("Sheet2")

    sourceSheetSum.Select

    sourceSheetSum.Range("C3").Select           'THIS IS THE PROBLEM LINE

End Sub

Replace Sheet1 and Sheet2 with your sheet names.

IMPORTANT NOTE: Using Variants is dangerous and can lead to difficult-to-kill bugs. Use them only if you have a very specific reason for doing so.

here i have solve my angularJS pagination issue with some more tweak in server side + view end you can check the code it will be more efficient. all i have to do is put two value start number and end number , it will represent index of the returned json array.

here is the angular

var refresh = function () {
    $('.loading').show();
    $http.get('http://put.php?OutputType=JSON&r=all&s=' + $scope.CountStart + '&l=' + $scope.CountEnd).success(function (response) {
        $scope.devices = response;


        $('.loading').hide();
    });
};

if you see carefully $scope.CountStart and $scope.CountStart are two argument i am passing with the api

here is the code for next button

$scope.nextPage = function () {
    $('.loading').css("display", "block");
    $scope.nextPageDisabled();


    if ($scope.currentPage >= 0) {
        $scope.currentPage++;

        $scope.CountStart = $scope.CountStart + $scope.DevicePerPage;
        $scope.CountEnd = $scope.CountEnd + $scope.DevicePerPage;
        refresh();
    }
};

here is the code for previous button

$scope.prevPage = function () {
    $('.loading').css("display", "block");
    $scope.nextPageDisabled();

    if ($scope.currentPage > 0) {
        $scope.currentPage--;

        $scope.CountStart = $scope.CountStart - $scope.DevicePerPage;
        $scope.CountEnd = $scope.CountEnd - $scope.DevicePerPage;

        refresh();

    }
};

if the page number is zero my previous button will be deactivated

   $scope.nextPageDisabled = function () {

    console.log($scope.currentPage);

    if ($scope.currentPage === 0) {
        return false;
    } else {
        return true;
    }
};

First Way:

In Kotlin we can create a simple extension for view:

fun View.getLocationOnScreen(): Point
{
    val location = IntArray(2)
    this.getLocationOnScreen(location)
    return Point(location[0],location[1])
}

And simply get coordinates:

val location = yourView.getLocationOnScreen()
val absX = location.x
val absY = location.y

Second Way:

The Second way is more simple :

fun View.absX(): Int
{
    val location = IntArray(2)
    this.getLocationOnScreen(location)
    return location[0]
}

fun View.absY(): Int
{
    val location = IntArray(2)
    this.getLocationOnScreen(location)
    return location[1]
}

and simply get absolute X by view.absX() and Y by view.absY()

Date range between 12/31/1996 and 12/31/2020

  EXTRACT(year from dt)*100        + EXTRACT(month from dt) as year_month_id,

Just three simple steps:

1. docker login --username username

   • prompts for password if you omit --password which is recommended as it doesn't store it in your command history

2. docker tag my-image username/my-repo

3. docker push username/my-repo

Since filter returns a QuerySet, you can use count to check how many results were returned. This is assuming you don't actually need the results.

num_results = User.objects.filter(email = cleaned_info['username']).count()

After looking at the documentation though, it's better to just call len on your filter if you are planning on using the results later, as you'll only be making one sql query:

A count() call performs a SELECT COUNT(*) behind the scenes, so you should always use count() rather than loading all of the record into Python objects and calling len() on the result (unless you need to load the objects into memory anyway, in which case len() will be faster).

num_results = len(user_object)

You could utilize jQuery.filter() function to return elements from a subset of the matching elements.

var names = [_x000D_
    { name : "Joe", age:20, email: "[email protected]"},_x000D_
    { name : "Mike", age:50, email: "[email protected]"},_x000D_
    { name : "Joe", age:45, email: "[email protected]"}_x000D_
   ];_x000D_
   _x000D_
   _x000D_
var filteredNames = $(names).filter(function( idx ) {_x000D_
    return names[idx].name === "Joe" && names[idx].age < 30;_x000D_
}); _x000D_
_x000D_
$(filteredNames).each(function(){_x000D_
     $('#output').append(this.name);_x000D_
});

driver = new ChromeDriver(chromeOptions);

This query is to convert the DateTimeOffset into the format yyyyMMddhhss with Offset. I have replaced the hyphens, colon(:), period(.) from the data, and kept the hyphen for the seperation of Offset from the DateTime.

SELECT REPLACE(SUBSTRING(CONVERT(VARCHAR(33),SYSDATETIMEOFFSET(),126), 1, 8), '-', '') +
SUBSTRING(REPLACE(REPLACE(REPLACE(CONVERT(VARCHAR(33), SYSDATETIMEOFFSET(), 126),'T',''),'.',''),':',''),9,DATALENGTH(CONVERT(VARCHAR(33), SYSDATETIMEOFFSET(), 126)))

I believe that dropping the size of the image down to an almost icon size, say 48x48, then converting to greyscale, then taking the difference between pixels, or Delta, should work well. Because we're comparing the change in pixel color, rather than the actual pixel color, it won't matter if the image is slightly lighter or darker. Large changes will matter since pixels getting too light/dark will be lost. You can apply this across one row, or as many as you like to increase the accuracy. At most you'd have 47x47=2,209 subtractions to make in order to form a comparable Key.

I had to be sure to change these settings in both the Target and Project settings on xCode 4.3.2 after doing that and setting it to build for both armv6 and armv7 everywhere I was able to submit my app.

For safe measure I also exited xCode between making the changes and doing a clean, build, archive cycle.

The use keyword is for aliasing in PHP and it does not import the classes. This really helps
1) When you have classes with same name in different namespaces
2) Avoid using really long class name over and over again.

I am using in the way and it is working for me.

public static void main(String[] args) {
    new CarpoolDBAppTest();

}

public CarpoolDBAppTest(){
    ApplicationContext context = new ClassPathXmlApplicationContext("application-context.xml");
    Student stud = (Student) context.getBean("yourBeanId");
}

Here Student is my classm you will get the class matching yourBeanId.

Now work on that object with whatever operation you want to do.

The following will do a dry run, as it says. HEAD being current version, PREV is previous, then the path to your file, or committed item:

svn merge --dry-run -rHEAD:PREV https://example.com/svn/myproject/trunk

If the dry run looks good, run the command without the --dry-run

Verify the change in revision and re-commit. To browse for version numbers try:

svn log

Their feature sets are not at all the same. Sqlite is an embedded database which has no network capabilities (unless you add them). So you can't use it on a network.

If you need

• Network access - for example accessing from another machine;
• Any real degree of concurrency - for example, if you think you are likely to want to run several queries at once, or run a workload that has lots of selects and a few updates, and want them to go smoothly etc.
• a lot of memory usage, for example, to buffer parts of your 1Tb database in your 32G of memory.

You need to use mysql or some other server-based RDBMS.

Note that MySQL is not the only choice and there are plenty of others which might be better for new applications (for example pgSQL).

Sqlite is a very, very nice piece of software, but it has never made claims to do any of these things that RDBMS servers do. It's a small library which runs SQL on local files (using locking to ensure that multiple processes don't screw the file up). It's really well tested and I like it a lot.

Also, if you aren't able to choose this correctly by yourself, you probably need to hire someone on your team who can.

With a SimpleXml object, you can simply

$domxml = new DOMDocument('1.0');
$domxml->preserveWhiteSpace = false;
$domxml->formatOutput = true;
/* @var $xml SimpleXMLElement */
$domxml->loadXML($xml->asXML());
$domxml->save($newfile);

$xml is your simplexml object

So then you simpleXml can be saved as a new file specified by $newfile

I needed to convert a single column of strings of form nn.n% to float. I needed to remove the % from the element in each row. The attend data frame has two columns.

attend.iloc[:,1:2]=attend.iloc[:,1:2].applymap(lambda x: float(x[:-1]))

Its an extenstion to the original answer. In my case it takes a dataframe and applies a function to each value in a specific column. The function removes the last character and converts the remaining string to float.

You just have to reset the values you don't want to their defaults. No need to get into a mess by using !important.

#zoomTarget .slikezamenjanje img {
    max-height: auto;
    padding-right: 0px;
}

Hatting

I think the key datum you are missing is that CSS comes with default values. If you want to override a value, set it back to its default, which you can look up.

For example, all CSS height and width attributes default to auto.

This is a FAQ:

//somexpression[$N]

means "Find every node selected by //somexpression that is the $Nth child of its parent".

What you want is:

(//input[@id="search_query"])[2]

Remember: The [] operator has higher precedence (priority) than the // abbreviation.

DateTime.Now is what you're searching for...

You can use the Unix-style -l switch – typically terse and cryptic – or the equivalent --files-with-matches – longer and more readable.

The output of grep --help is not easy to read, but it's there:

Valentin Rocher's method works if you've extended your view, but if you're using an event listener, use this:

view.setOnTouchListener(new OnTouchListener()
{
    public boolean onTouch(View v, MotionEvent event)
    {
        Toast toast = Toast.makeText(
            getApplicationContext(), 
            "View touched", 
            Toast.LENGTH_LONG
        );
        toast.show();

        return true;
    }
});


// Obtain MotionEvent object
long downTime = SystemClock.uptimeMillis();
long eventTime = SystemClock.uptimeMillis() + 100;
float x = 0.0f;
float y = 0.0f;
// List of meta states found here: developer.android.com/reference/android/view/KeyEvent.html#getMetaState()
int metaState = 0;
MotionEvent motionEvent = MotionEvent.obtain(
    downTime, 
    eventTime, 
    MotionEvent.ACTION_UP, 
    x, 
    y, 
    metaState
);

// Dispatch touch event to view
view.dispatchTouchEvent(motionEvent);

For more on obtaining a MotionEvent object, here is an excellent answer: Android: How to create a MotionEvent?

First check that the extension is properly loaded in phpinfo(); (something like sqlsrv should appear). If not, the extension isn't properly loaded. You also need to restart apache after installing an extension.

This only hovers the navbar when you are not on a mobile device, because I find that hovering the navigation does not work well on mobile divices:

    $( document ).ready(function() {

    $( 'ul.nav li.dropdown' ).hover(function() {
        // you could also use this condition: $( window ).width() >= 768
        if ($('.navbar-toggle').css('display') === 'none' 
            && false === ('ontouchstart' in document)) {

            $( '.dropdown-toggle', this ).trigger( 'click' );
        }
    }, function() {
        if ($('.navbar-toggle').css('display') === 'none'
            && false === ('ontouchstart' in document)) {

            $( '.dropdown-toggle', this ).trigger( 'click' );
        }
    });

});

Untested. Modify to suit:

$form = $('#my-form');

$rows = $form.find('.person-input-row');

$('button#add-new').click(function() {

    $rows.find(':first').clone().insertAfter($rows.find(':last'));

    $justInserted = $rows.find(':last');
    $justInserted.hide();
    $justInserted.find('input').val(''); // it may copy values from first one
    $justInserted.slideDown(500);


});

This is better than copying innerHTML because you will lose all attached events etc.

You need to use the scrollTop property.

document.getElementById('box').scrollTop

I was looking for the same thing since the background of my select is the same as the arrow color. As previously mentioned, it is impossible yet to add anything using :before or :after on a select element. My solution was to create a wrapper element on which I added the following :before code.

.select-wrapper {
    position: relative;
}

.select-wrapper:before {
    content: '\f0d7';
    font-family: FontAwesome;
    color: #fff;
    display: inline-block;
    position: absolute;
    right: 20px;
    top: 15px;
    pointer-events: none;
}

And this my select

select {
    box-sizing: border-box;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    width: 100%;
    padding: 10px 20px;
    background: #000;
    color: #fff;
    border: none;
    -webkit-appearance: none;
    -moz-appearance: none;
    appearance: none;
}

select::-ms-expand {
    display: none;
}

I have used FontAwesome.io for my new arrow, but you can use whatever else you want. Obviously this is not a perfect solution, but depending on your needs it might be enough.

If you want to break a string literal onto multiple lines, you can concatenate multiple strings together, one on each line, like so:

printf("name: %s\t"
"args: %s\t"
"value %d\t"
"arraysize %d\n", 
sp->name, 
sp->args, 
sp->value, 
sp->arraysize);

This worked for me to stop silly work breaks from happening within Chrome textareas

word-break: keep-all;

One thing that has not been mentioned in these answers is that if you are using IIS and have sub applications with their own separate web.config, you may need to have a web.config in the parent directory containing the following code.

<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*"/>
    <add name="Access-Control-Allow-Headers" value="Content-Type"/>
    <add name="Access-Control-Allow-Methods" value="POST,GET,OPTIONS"/>
  </customHeaders>
</httpProtocol>

Atom is still in beta (v0.123 as I'm writing this) but it's moving fast. Way faster than Sublime. New builds are released on a weekly basis, sometimes even few of them in the same week. In its short life span, it had more releases than Sublime which takes months to release a new feature or a bug fix. Here's an updated take on things looking back on the path Atom has taken since the launch of the beta:

1. Sublime has better performance than Atom. Simply because it's written in C++. Atom on the other hand is a web based desktop app built on top of Chromium, and while they take performance close to heart, it will be really hard or even impossible to reach the same speed and responsiveness. Last July Atom began using React and it gave it a nice performance boost but you can still feel the difference. Apart from that, if Atom’s performance issues will not push users away - Sublime better speed up the release cycle, brush up its small UX tweaks, and consider letting in more contributors because this is where Atom is winning.

2. Atom's package ecosystem is also growing really fast, it might not be as big as Sublime's at the moment but I have a feeling that with GitHub at it's back it will keep growing even faster. It probably has the majority of IDE like plug-ins you can think of. A major difference right now is that it can't handle files bigger than 2MB so it's something to keep in mind.

3. The one thing you'll notice first is that the Sublime minimap is gone! Other than that, the first impression is that Atom looks almost the same as Sublime. I wrote a more in depth comparison about it in this blog post.

4. No easy straightforward way to port your Sublime configurations, packages and such as far as I know.

There is no way to do this in single query. You have to search the document in first query:

If document exists:

db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } , 
                {$inc : {"items.$.price" : 1} } , 
                false , 
                true);

Else

db.bar.update( {user_id : 123456 } , 
                {$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
                false , 
                true);

No need to add condition {$ne : "my_item_two" }.

Also in multithreaded enviourment you have to be careful that only one thread can execute the second (insert case, if document did not found) at a time, otherwise duplicate embed documents will be inserted.

This worked for me .

.tooltip .arrow:before {
    border-top-color: #008ec3 !important;
}

.tooltip .tooltip-inner {
    background-color: #008ec3;
}

Running from the command line means running from the terminal or DOS shell. You are running it from Python itself.

There are lots of options out there. Many of which are available as downloadable software as well as public websites. I do not think many of them expect to be used as API's unless they explicitly state that.

The one that I found effective was Enju which did not have the character limit that the Marc's Carnagie Mellon link had. Marc also mentioned a VISL scanner in comments, but that requires java in the browser, which is a non-starter for me.

Note that recently, Google has offered a new NLP Machine Learning API that providers amoung other features, a automatic sentence parser. I will likely not update this answer again, especially since the question is closed, but I suspect that the other big ML cloud stacks will soon support the same.

You have to inherit nusoap.php class and put it in your project directory, you can download it from the Internet.

Use this code:

require_once('nusoap.php');

This example shows you how to fill column B based on the the volume of data in Column A. Adjust "A1" accordingly to your needs. It will fill in column B based on the formula in B1.

Range("A1").Select
Selection.End(xlDown).Select
ActiveCell.Offset(0, 1).Select
Range(Selection, Selection.End(xlUp)).Select
Selection.FillDown

1. Close Anaconda/Spyder
2. Open command prompt and run the below command
3. conda update --all
4. Start the app again and this time it should work.

Note - You need not have to uninstall/reinstall anything.

import request
response = requests.get("url/api that you want to hit", verify="path to ssl certificate")

For me the problem was that none of the above answers completely helped me but gave me the right direction to look at.

For sure, SSL certificate is needed but when you are behind the company's firewall then publicly available certificates might not help. You might need to reach out to the IT department of your company to obtain the certificate as each company uses special certificate from the security provider they have contracted the services from. And place it in a folder and pass the path to that folder as an argument to verify parameter.

For me even after trying all the above solutions and using the wrong certificate I was not able to make it work. So just remember for those who are behind company's firewall to obtain the right certificate. It can make a difference between success and failure of your request call.

In my case I placed the certificate in the following path and it worked like magic.

C:\Program Files\Common Files\ssl

You could also refer https://2.python-requests.org/en/master/user/advanced/#id3 which talks about ssl verification

UPDATE

Now it's available:

https://marketplace.visualstudio.com/items?itemName=donjayamanne.githistory

Until now it isn't supported, but you can follow the thread for it: GitHub

You need to include Pods-generated xcconfig path in your customized xcconfig. For me this was due to that misconfigured xcconfig file.

You can add a PPA that provides a relatively current version of SmartGit(as well as SmartGitHg, the predecessor of SmartGit).

To add the PPA run:

sudo add-apt-repository ppa:eugenesan/ppa
sudo apt-get update

To install smartgit (after adding the PPA) run:

sudo apt-get install smartgit

To install smartgithg (after adding the PPA) run:

sudo apt-get install smartgithg

This should add a menu option for you

For more information, see Eugene San PPA.

This repository contains collection of customized, updated, ported and backported packages for two last LTS releases and latest pre-LTS release

public static void Each<T>(this IEnumerable<T> items, Action<T> action) {
foreach (var item in items) {
    action(item);
} }

... and call it thusly:

myList.Each(x => { x.Enabled = false; });

json.dumps() is used to decode JSON data

import json

# initialize different data
str_data = 'normal string'
int_data = 1
float_data = 1.50
list_data = [str_data, int_data, float_data]
nested_list = [int_data, float_data, list_data]
dictionary = {
    'int': int_data,
    'str': str_data,
    'float': float_data,
    'list': list_data,
    'nested list': nested_list
}

# convert them to JSON data and then print it
print('String :', json.dumps(str_data))
print('Integer :', json.dumps(int_data))
print('Float :', json.dumps(float_data))
print('List :', json.dumps(list_data))
print('Nested List :', json.dumps(nested_list, indent=4))
print('Dictionary :', json.dumps(dictionary, indent=4))  # the json data will be indented

output:

String : "normal string"
Integer : 1
Float : 1.5
List : ["normal string", 1, 1.5]
Nested List : [
    1,
    1.5,

json.loads() is used to convert JSON data into Python data.

import json

# initialize different JSON data
arrayJson = '[1, 1.5, ["normal string", 1, 1.5]]'
objectJson = '{"a":1, "b":1.5 , "c":["normal string", 1, 1.5]}'

# convert them to Python Data
list_data = json.loads(arrayJson)
dictionary = json.loads(objectJson)

print('arrayJson to list_data :\n', list_data)
print('\nAccessing the list data :')
print('list_data[2:] =', list_data[2:])
print('list_data[:1] =', list_data[:1])

print('\nobjectJson to dictionary :\n', dictionary)
print('\nAccessing the dictionary :')
print('dictionary[\'a\'] =', dictionary['a'])
print('dictionary[\'c\'] =', dictionary['c'])

output:

arrayJson to list_data :
 [1, 1.5, ['normal string', 1, 1.5]]

Accessing the list data :
list_data[2:] = [['normal string', 1, 1.5]]
list_data[:1] = [1]

You need to use the Thread.sleep() call.

More info here: http://docs.oracle.com/javase/tutorial/essential/concurrency/sleep.html

Using the lambda function you can filter the rows with _merge value “left_only” to get all the rows in df1 which are missing from df2

df3 = df1.merge(df2, how = 'outer' ,indicator=True).loc[lambda x :x['_merge']=='left_only']
df

If your goal is to have

str = "Hello\nWorld";

and output what it contains in string literal form, you can use JSON.stringify:

console.log(JSON.stringify(str)); // ""Hello\nWorld""

const str = "Hello\nWorld";_x000D_
const json = JSON.stringify(str);_x000D_
console.log(json); // ""Hello\nWorld""_x000D_
for (let i = 0; i < json.length; ++i) {_x000D_
    console.log(`${i}: ${json.charAt(i)}`);_x000D_
}

.as-console-wrapper {_x000D_
    max-height: 100% !important;_x000D_
}

console.log adds the outer quotes (at least in Chrome's implementation), but the content within them is a string literal (yes, that's somewhat confusing).

JSON.stringify takes what you give it (in this case, a string) and returns a string containing valid JSON for that value. So for the above, it returns an opening quote ("), the word Hello, a backslash (\), the letter n, the word World, and the closing quote ("). The linefeed in the string is escaped in the output as a \ and an n because that's how you encode a linefeed in JSON. Other escape sequences are similarly encoded.

I tested the following code in all major browsers, including older Explorers (via the compatibility mode), and it works well everywhere:

$filename = $_GET['file']; //this string from $_GET is already decoded
if (strstr($_SERVER['HTTP_USER_AGENT'],"MSIE"))
  $filename = rawurlencode($filename);
header('Content-Disposition: attachment; filename="'.$filename.'"');

SELECT c1, c2, c3, ... INTO @v1, @v2, @v3,... FROM table_name WHERE condition;

Usually, I don't care about the order of the calls, only that they happened. In that case, I combine assert_any_call with an assertion about call_count.

>>> import mock
>>> m = mock.Mock()
>>> m(1)
<Mock name='mock()' id='37578160'>
>>> m(2)
<Mock name='mock()' id='37578160'>
>>> m(3)
<Mock name='mock()' id='37578160'>
>>> m.assert_any_call(1)
>>> m.assert_any_call(2)
>>> m.assert_any_call(3)
>>> assert 3 == m.call_count
>>> m.assert_any_call(4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "[python path]\lib\site-packages\mock.py", line 891, in assert_any_call
    '%s call not found' % expected_string
AssertionError: mock(4) call not found

I find doing it this way to be easier to read and understand than a large list of calls passed into a single method.

If you do care about order or you expect multiple identical calls, assert_has_calls might be more appropriate.

Edit

Since I posted this answer, I've rethought my approach to testing in general. I think it's worth mentioning that if your test is getting this complicated, you may be testing inappropriately or have a design problem. Mocks are designed for testing inter-object communication in an object oriented design. If your design is not objected oriented (as in more procedural or functional), the mock may be totally inappropriate. You may also have too much going on inside the method, or you might be testing internal details that are best left unmocked. I developed the strategy mentioned in this method when my code was not very object oriented, and I believe I was also testing internal details that would have been best left unmocked.

Either lock or interlocked increment is what you are looking for.

Volatile is definitely not what you're after - it simply tells the compiler to treat the variable as always changing even if the current code path allows the compiler to optimize a read from memory otherwise.

e.g.

while (m_Var)
{ }

if m_Var is set to false in another thread but it's not declared as volatile, the compiler is free to make it an infinite loop (but doesn't mean it always will) by making it check against a CPU register (e.g. EAX because that was what m_Var was fetched into from the very beginning) instead of issuing another read to the memory location of m_Var (this may be cached - we don't know and don't care and that's the point of cache coherency of x86/x64). All the posts earlier by others who mentioned instruction reordering simply show they don't understand x86/x64 architectures. Volatile does not issue read/write barriers as implied by the earlier posts saying 'it prevents reordering'. In fact, thanks again to MESI protocol, we are guaranteed the result we read is always the same across CPUs regardless of whether the actual results have been retired to physical memory or simply reside in the local CPU's cache. I won't go too far into the details of this but rest assured that if this goes wrong, Intel/AMD would likely issue a processor recall! This also means that we do not have to care about out of order execution etc. Results are always guaranteed to retire in order - otherwise we are stuffed!

With Interlocked Increment, the processor needs to go out, fetch the value from the address given, then increment and write it back -- all that while having exclusive ownership of the entire cache line (lock xadd) to make sure no other processors can modify its value.

With volatile, you'll still end up with just 1 instruction (assuming the JIT is efficient as it should) - inc dword ptr [m_Var]. However, the processor (cpuA) doesn't ask for exclusive ownership of the cache line while doing all it did with the interlocked version. As you can imagine, this means other processors could write an updated value back to m_Var after it's been read by cpuA. So instead of now having incremented the value twice, you end up with just once.

Hope this clears up the issue.

p.s. What prompted this very late reply? All the replies were so blatantly incorrect (especially the one marked as answer) in their explanation I just had to clear it up for anyone else reading this. shrugs

p.p.s. I'm assuming that the target is x86/x64 and not IA64 (it has a different memory model). Note that Microsoft's ECMA specs is screwed up in that it specifies the weakest memory model instead of the strongest one (it's always better to specify against the strongest memory model so it is consistent across platforms - otherwise code that would run 24-7 on x86/x64 may not run at all on IA64 although Intel has implemented similarly strong memory model for IA64) - Microsoft admitted this themselves - http://blogs.msdn.com/b/cbrumme/archive/2003/05/17/51445.aspx.

    }

There is a great book called Chaos and Fractals that has simple example code at the end of each chapter that implements some fractal or other example. A long time ago when I read that book, I converted each sample program (in some Basic dialect) into a Java applet that runs on a web page. The applets are here: http://hewgill.com/chaos-and-fractals/

One of the samples is a simple Mandelbrot implementation.

This is a bit old, but I guess what you want is: ps -o pid -C PROCESS_NAME, for example:

ps -o pid -C bash

EDIT: Dependening on the sort of output you expect, pgrep would be more elegant. This, in my knowledge, is Linux specific and result in similar output as above. For example:

pgrep bash

If you want to put the files from a branch in repo B in a subtree of repo A and also preserve the history, keep reading. (In the example below, I am assuming that we want repo B's master branch merged into repo A's master branch.)

In repo A, first do the following to make repo B available:

git remote add B ../B # Add repo B as a new remote.
git fetch B

Now we create a brand new branch (with only one commit) in repo A that we call new_b_root. The resulting commit will have the files that were committed in the first commit of repo B's master branch but put in a subdirectory called path/to/b-files/.

git checkout --orphan new_b_root master
git rm -rf . # Remove all files.
git cherry-pick -n `git rev-list --max-parents=0 B/master`
mkdir -p path/to/b-files
git mv README path/to/b-files/
git commit --date="$(git log --format='%ai' $(git rev-list --max-parents=0 B/master))"

Explanation: The --orphan option to the checkout command checks out the files from A's master branch but doesn't create any commit. We could have selected any commit because next we clear out all the files anyway. Then, without committing yet (-n), we cherry-pick the first commit from B's master branch. (The cherry-pick preserves the original commit message which a straight checkout doesn't seem to do.) Then we create the subtree where we want to put all files from repo B. We then have to move all files that were introduced in the cherry-pick to the subtree. In the example above, there's only a README file to move. Then we commit our B-repo root commit, and, at the same time, we also preserve the timestamp of the original commit.

Now, we'll create a new B/master branch on top of the newly created new_b_root. We call the new branch b:

git checkout -b b B/master
git rebase -s recursive -Xsubtree=path/to/b-files/ new_b_root

Now, we merge our b branch into A/master:

git checkout master
git merge --allow-unrelated-histories --no-commit b
git commit -m 'Merge repo B into repo A.'

Finally, you can remove the B remote and temporary branches:

git remote remove B
git branch -D new_b_root b

The final graph will have a structure like this:

I think there is an error in the trigger code. As you want to delete all rows with the deleted patron ID, you have to use old.id (Otherwise it would delete other IDs)

Try this as the new trigger:

CREATE TRIGGER log_patron_delete AFTER DELETE on patrons
FOR EACH ROW
BEGIN
DELETE FROM patron_info
    WHERE patron_info.pid = old.id;
END

Dont forget the ";" on the delete query. Also if you are entering the TRIGGER code in the console window, make use of the delimiters also.

%u is used for unsigned integer. Since the memory address given by the signed integer address operator %d is -12, to get this value in unsigned integer, Compiler returns the unsigned integer value for this address.

You can also use:

@if(string.IsNullOrEmpty(Model.CreatorFullName))
{
...your code...
}

No need for a variable in the code

I suggest you to use Message Properte from The Exception Object Like below code

try
{
 object result = processClass.InvokeMethod("Create", methodArgs);
}
catch (Exception e)
{  
    //use Console.Write(e.Message); from Console Application 
    //and use MessageBox.Show(e.Message); from WindowsForm and WPF Application
}

Very rarely.

I'd say only at the top level of a thread in order to ATTEMPT to issue a message with the reason for a thread dying.

If you are in a framework that does this sort of thing for you, leave it to the framework.

Public Function connectDB() As OleDbConnection

        Dim Con As New OleDbConnection
        'Con.ConnectionString = "Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Initial Catalog=" & DBNAME & ";Data Source=" & DBSERVER & ";Pwd=" & DBPWD & ""
        Con.ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=DBNAME;Data Source=DBSERVER-TOSH;User ID=Sa;Pwd= & DBPWD"
        Try
            Con.Open()
        Catch ex As Exception
            showMessage(ex)
        End Try
        Return Con
    End Function

Too late for you, but for anyone else with the same question...

//a[contains(text(), 'programming')]/@href

Of course, 'programming' can be any text fragment.

You can also take a look at PDFMiner (or for older versions of Python see PDFMiner and PDFMiner).

A particular feature of interest in PDFMiner is that you can control how it regroups text parts when extracting them. You do this by specifying the space between lines, words, characters, etc. So, maybe by tweaking this you can achieve what you want (that depends of the variability of your documents). PDFMiner can also give you the location of the text in the page, it can extract data by Object ID and other stuff. So dig in PDFMiner and be creative!

But your problem is really not an easy one to solve because, in a PDF, the text is not continuous, but made from a lot of small groups of characters positioned absolutely in the page. The focus of PDF is to keep the layout intact. It's not content oriented but presentation oriented.

Short answer:

ALTER SCHEMA new_schema TRANSFER old_schema.table_name

I can confirm that the data in the table remains intact, which is probably quite important :)

Long answer as per MSDN docs,

ALTER SCHEMA schema_name 
   TRANSFER [ Object | Type | XML Schema Collection ] securable_name [;]

If it's a table (or anything besides a Type or XML Schema collection), you can leave out the word Object since that's the default.

In a nutshell, sys.argv is a list of the words that appear in the command used to run the program. The first word (first element of the list) is the name of the program, and the rest of the elements of the list are any arguments provided. In most computer languages (including Python), lists are indexed from zero, meaning that the first element in the list (in this case, the program name) is sys.argv[0], and the second element (first argument, if there is one) is sys.argv[1], etc.

The test len(sys.argv) >= 2 simply checks wither the list has a length greater than or equal to 2, which will be the case if there was at least one argument provided to the program.

An example of how to implement it:

public bool ValidateSocialSecNumber(string socialSecNumber)
{
    //Accepts only 10 digits, no more no less. (Like Mike's answer)
    Regex pattern = new Regex(@"(?<!\d)\d{10}(?!\d)");

    if(pattern.isMatch(socialSecNumber))
    {
        //Do something
        return true;
    }
    else
    {
        return false;
    }
}

You could've also done it in another way by e.g. using Match and then wrapping a try-catch block around the pattern matching. However, if a wrong input is given quite often, it's quite expensive to throw an exception. Thus, I prefer the above way, in simple cases at least.

You can't use PHP in the WordPress back-end Page editor. Maybe with a plugin you can, but not out of the box.

The easiest solution for this is creating a shortcode. Then you can use something like this

function input_func( $atts ) {
    extract( shortcode_atts( array(
        'type' => 'text',
        'name' => '',
    ), $atts ) );

    return '<input name="' . $name . '" id="' . $name . '" value="' . (isset($_GET\['from'\]) && $_GET\['from'\] ? $_GET\['from'\] : '') . '" type="' . $type . '" />';
}
add_shortcode( 'input', 'input_func' );

See the Shortcode_API.

As many have mentioned previously, you must convert each column to string and then use the plus operator to combine two string columns. You can get a large performance improvement by using NumPy.

%timeit df['Year'].values.astype(str) + df.quarter
71.1 ms ± 3.76 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

%timeit df['Year'].astype(str) + df['quarter']
565 ms ± 22.3 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

Actully what work for me is:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE, WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);

and to undo it:

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);

jkoreska's solution is perfect if you know the titles before hand, but you may need to set the title based on data you get from a resource etc.

My solution requires a single service. Since the rootScope is the base of all DOM elements, we don't need to put a controller on the html element like someone mentioned

Page.js

app.service('Page', function($rootScope){
    return {
        setTitle: function(title){
            $rootScope.title = title;
        }
    }
});

index.jade

doctype html
html(ng-app='app')
head
    title(ng-bind='title')
// ...

All controllers that need to change title

app.controller('SomeController', function(Page){
    Page.setTitle("Some Title");
});

I've created a factory that controls shared scope between route path's pattern, so you can maintain the shared data just when users are navigating in the same route parent path.

.controller('CadastroController', ['$scope', 'RouteSharedScope',
    function($scope, routeSharedScope) {
      var customerScope = routeSharedScope.scopeFor('/Customer');
      //var indexScope = routeSharedScope.scopeFor('/');
    }
 ])

So, if the user goes to another route path, for example '/Support', the shared data for path '/Customer' will be automatically destroyed. But, if instead of this the user goes to 'child' paths, like '/Customer/1' or '/Customer/list' the the scope won't be destroyed.

You can see an sample here: http://plnkr.co/edit/OL8of9

If Machine A is a Windows box, you can use Plink (part of PuTTY) with the -m parameter, and it will execute the local script on the remote server.

plink root@MachineB -m local_script.sh

If Machine A is a Unix-based system, you can use:

ssh root@MachineB 'bash -s' < local_script.sh

You shouldn't have to copy the script to the remote server to run it.

Think about what

if ((state != 10) || (state != 15) || (state != 19) || (state != 22) || (state != 33) || (state != 39) || (state != 47) || (state != 48) || (state != 49) || (state != 51))

means. || means "or." The negation of this is (by DeMorgan's Laws):

state == 10 && state == 15 && state == 19...

In other words, the only way that this could be false if if a state equals 10, 15, and 19 (and the rest of the numbers in your or statement) at the same time, which is impossible.

Thus, this statement will always be true. State 15 will never equal state 10, for example, so it's always true that state will either not equal 10 or not equal 15.

Change || to &&.

Also, in most languages, the following:

if (x) {
  return true;
}
else {
  return false;
}

is not necessary. In this case, the method returns true exactly when x is true and false exactly when x is false. You can just do:

return x;

In order to connect my git bash to the postgreSQL, I had to add at least 4 environment variables to the windows. Git, Node.js, System 32 and postgreSQL. This is what I set as the value for the Path variable: C:\Windows\System32;C:\Program Files\Git\cmd;C:\Program Files\nodejs;C:\Program Files\PostgreSQL\12\bin; and It works perfectly.

I wasn't able to get @Alex Poole answers working. However, by trial and error, I found the following works (using SQL Developer version 3.0.04). Posting it here in case it helps others:

SET serveroutput on;

DECLARE
    var InParam1 number;
    var InParam2 number;
    var OutParam1 varchar2(100);
    var OutParam2 varchar2(100);
    var OutParam3 varchar2(100);
    var OutParam4 number;

BEGIN
    /* Assign values to IN parameters */
    InParam1 := 33;
    InParam2 := 89;

    /* Call procedure within package, identifying schema if necessary */
    schema.package.procedure(InParam1, InParam2,
        OutParam1, OutParam2, OutParam3, OutParam4);

    /* Display OUT parameters */
    dbms_output.put_line('OutParam1: ' || OutParam1);
    dbms_output.put_line('OutParam2: ' || OutParam2);
    dbms_output.put_line('OutParam3: ' || OutParam3);
    dbms_output.put_line('OutParam4: ' || OutParam4);
END;

What about just: :%s/\r//g That totally worked for me.

What this does is just to clean the end of line of all lines, it removes the ^M and that's it.

Maybe one of the easiest solutions would be to use the x descriptor of the srcset attribute as such:

<!-- Original image -->
<img src="https://fr.wikipedia.org/static/images/mobile/copyright/wikipedia.png" />

<!-- With a 80% size reduction (1/0.8=1.25) -->
<img srcset="https://fr.wikipedia.org/static/images/mobile/copyright/wikipedia.png 1.25x" />

<!-- With a 50% size reduction (1/0.5=2) -->
<img srcset="https://fr.wikipedia.org/static/images/mobile/copyright/wikipedia.png 2x" />

Currently supported by all browsers except IE. (caniuse)

You can use $addToSet with the aggregation framework to count distinct objects.

For example:

db.collectionName.aggregate([{
    $group: {_id: null, uniqueValues: {$addToSet: "$fieldName"}}
}])

    public static string Serialize(object dataToSerialize)
    {
        if(dataToSerialize==null) return null;

        using (StringWriter stringwriter = new System.IO.StringWriter())
        {
            var serializer = new XmlSerializer(dataToSerialize.GetType());
            serializer.Serialize(stringwriter, dataToSerialize);
            return stringwriter.ToString();
        }
    }

    public static T Deserialize<T>(string xmlText)
    {
        if(String.IsNullOrWhiteSpace(xmlText)) return default(T);

        using (StringReader stringReader = new System.IO.StringReader(xmlText))
        {
            var serializer = new XmlSerializer(typeof(T));
            return (T)serializer.Deserialize(stringReader);
        }
    }

If you prefer simplicity and more control on SQL queries then I would suggest going with Spring Data/ Spring JDBC.

Its good amount of learning curve in JPA and sometimes difficult to debug issues. On the other hand, while you have full control over SQL, it becomes much easier to optimize query and improve performance. You can easily share your SQL with DBA or someone who has a better understanding of Database.

In case if one is using nginx proxy as a docker container (e.g. jwilder/nginx-proxy), there is the following way to configure client_max_body_size (or other properties):

1. Create a custom config file e.g. /etc/nginx/proxy.conf with a right value for this property
2. When running a container, add it as a volume e.g. -v /etc/nginx/proxy.conf:/etc/nginx/conf.d/my_proxy.conf:ro

Personally found this way rather convenient as there's no need to build a custom container to change configs. I'm not affiliated with jwilder/nginx-proxy, was just using it in my project, and the way described above helped me. Hope it helps someone else, too.

Say the hierarchy is C->B->A with A being the base class.

I think there's more to fixing this than renaming a method. That will work but is that a fix?

One way is to refactor all the functionality common to B and C into D, and let B and C inherit from D: (B,C)->D->A Now the method in B that was hiding A's implementation from C is specific to B and stays there. This allows C to invoke the method in A without any hokery.

You can use groupBy of angular.filter module.
so you can do something like this:

JS:

$scope.players = [
  {name: 'Gene', team: 'alpha'},
  {name: 'George', team: 'beta'},
  {name: 'Steve', team: 'gamma'},
  {name: 'Paula', team: 'beta'},
  {name: 'Scruath', team: 'gamma'}
];

HTML:

<ul ng-repeat="(key, value) in players | groupBy: 'team'">
  Group name: {{ key }}
  <li ng-repeat="player in value">
    player: {{ player.name }} 
  </li>
</ul>

RESULT:
Group name: alpha
* player: Gene
Group name: beta
* player: George
* player: Paula
Group name: gamma
* player: Steve
* player: Scruath

UPDATE: jsbin Remember the basic requirements to use angular.filter, specifically note you must add it to your module's dependencies:

(1) You can install angular-filter using 4 different methods:

1. clone & build this repository
2. via Bower: by running $ bower install angular-filter from your terminal
3. via npm: by running $ npm install angular-filter from your terminal
4. via cdnjs http://www.cdnjs.com/libraries/angular-filter

(2) Include angular-filter.js (or angular-filter.min.js) in your index.html, after including Angular itself.

(3) Add 'angular.filter' to your main module's list of dependencies.

Its better to access the count with the laravels count method

$count = Model::where('status','=','1')->count();

or

$count = Model::count();

This is the shortest version I could find,saving/hiding an extra conversion:

pil_image = PIL.Image.open('image.jpg')
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)

If reading a file from a URL:

import cStringIO
import urllib
file = cStringIO.StringIO(urllib.urlopen(r'http://stackoverflow.com/a_nice_image.jpg').read())
pil_image = PIL.Image.open(file)
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)

A simple DIY way would be to make the grid yourself:

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)

ax.plot([1,2,3], [2,3,4], 'ro')

for xmaj in ax.xaxis.get_majorticklocs():
  ax.axvline(x=xmaj, ls='-')
for xmin in ax.xaxis.get_minorticklocs():
  ax.axvline(x=xmin, ls='--')

for ymaj in ax.yaxis.get_majorticklocs():
  ax.axhline(y=ymaj, ls='-')
for ymin in ax.yaxis.get_minorticklocs():
  ax.axhline(y=ymin, ls='--')
plt.show()

I tested below code with SQL Server 2008 R2 Express and I believe we should have solution for all 6 steps you outlined. Let's take on them one-by-one:

1 - Enable TCP/IP

We can enable TCP/IP protocol with WMI:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProtocols = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocol " _
    & "where InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'")

if tcpProtocols.Count = 1 then
    ' set tcpProtocol = tcpProtocols(0)
    ' I wish this worked, but unfortunately 
    ' there's no int-indexed Item property in this type

    ' Doing this instead
    for each tcpProtocol in tcpProtocols
        dim setEnableResult
            setEnableResult = tcpProtocol.SetEnable()
            if setEnableResult <> 0 then 
                Wscript.Echo "Failed!"
            end if
    next
end if

2 - Open the right ports in the firewall

I believe your solution will work, just make sure you specify the right port. I suggest we pick a different port than 1433 and make it a static port SQL Server Express will be listening on. I will be using 3456 in this post, but please pick a different number in the real implementation (I feel that we will see a lot of applications using 3456 soon :-)

3 - Modify TCP/IP properties enable a IP address

We can use WMI again. Since we are using static port 3456, we just need to update two properties in IPAll section: disable dynamic ports and set the listening port to 3456:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProperties = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocolProperty " _
    & "where InstanceName='SQLEXPRESS' and " _
    & "ProtocolName='Tcp' and IPAddressName='IPAll'")

for each tcpProperty in tcpProperties
    dim setValueResult, requestedValue

    if tcpProperty.PropertyName = "TcpPort" then
        requestedValue = "3456"
    elseif tcpProperty.PropertyName ="TcpDynamicPorts" then
        requestedValue = ""
    end if

    setValueResult = tcpProperty.SetStringValue(requestedValue)
    if setValueResult = 0 then 
        Wscript.Echo "" & tcpProperty.PropertyName & " set."
    else
        Wscript.Echo "" & tcpProperty.PropertyName & " failed!"
    end if
next

Note that I didn't have to enable any of the individual addresses to make it work, but if it is required in your case, you should be able to extend this script easily to do so.

Just a reminder that when working with WMI, WBEMTest.exe is your best friend!

4 - Enable mixed mode authentication in sql server

I wish we could use WMI again, but unfortunately this setting is not exposed through WMI. There are two other options:

1. Use LoginMode property of Microsoft.SqlServer.Management.Smo.Server class, as described here.

2. Use LoginMode value in SQL Server registry, as described in this post. Note that by default the SQL Server Express instance is named SQLEXPRESS, so for my SQL Server 2008 R2 Express instance the right registry key was HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQLServer.

5 - Change user (sa) default password

You got this one covered.

6 - Finally (connect to the instance)

Since we are using a static port assigned to our SQL Server Express instance, there's no need to use instance name in the server address anymore.

SQLCMD -U sa -P newPassword -S 192.168.0.120,3456

Please let me know if this works for you (fingers crossed!).

I would suggest you to test it firstly: copy this train.csv to the same directory as this jupyter script in and then change the path to train.csv to test whether this can be loaded successfully.

If yes, that means the previous path input is a problem

If not, that means the file it self denied your access to it, or its real filename can be something else like: train.csv.<hidden extension>

use

document.getElementsByTagName(" * ");

to get all XML elements from within an XML file, this does however return repeating attributes

example:

NodeList list = doc.getElementsByTagName("*");

System.out.println("XML Elements: ");

        for (int i=0; i<list.getLength(); i++) {

            Element element = (Element)list.item(i);
            System.out.println(element.getNodeName());
        }

EDIT 2017-04-29: As pointed to by some of the commenters, the JoinTable example does not need the mappedBy annotation attribute. In fact, recent versions of Hibernate refuse to start up by printing the following error:

org.hibernate.AnnotationException: 
   Associations marked as mappedBy must not define database mappings 
   like @JoinTable or @JoinColumn

Let's pretend that you have an entity named Project and another entity named Task and each project can have many tasks.

You can design the database schema for this scenario in two ways.

The first solution is to create a table named Project and another table named Task and add a foreign key column to the task table named project_id:

Project      Task
-------      ----
id           id
name         name
             project_id

This way, it will be possible to determine the project for each row in the task table. If you use this approach, in your entity classes you won't need a join table:

@Entity
public class Project {

   @OneToMany(mappedBy = "project")
   private Collection<Task> tasks;

}

@Entity
public class Task {

   @ManyToOne
   private Project project;

}

The other solution is to use a third table, e.g. Project_Tasks, and store the relationship between projects and tasks in that table:

Project      Task      Project_Tasks
-------      ----      -------------
id           id        project_id
name         name      task_id

The Project_Tasks table is called a "Join Table". To implement this second solution in JPA you need to use the @JoinTable annotation. For example, in order to implement a uni-directional one-to-many association, we can define our entities as such:

Project entity:

@Entity
public class Project {

    @Id
    @GeneratedValue
    private Long pid;

    private String name;

    @JoinTable
    @OneToMany
    private List<Task> tasks;

    public Long getPid() {
        return pid;
    }

    public void setPid(Long pid) {
        this.pid = pid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List<Task> getTasks() {
        return tasks;
    }

    public void setTasks(List<Task> tasks) {
        this.tasks = tasks;
    }
}

Task entity:

@Entity
public class Task {

    @Id
    @GeneratedValue
    private Long tid;

    private String name;

    public Long getTid() {
        return tid;
    }

    public void setTid(Long tid) {
        this.tid = tid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

This will create the following database structure:

The @JoinTable annotation also lets you customize various aspects of the join table. For example, had we annotated the tasks property like this:

@JoinTable(
        name = "MY_JT",
        joinColumns = @JoinColumn(
                name = "PROJ_ID",
                referencedColumnName = "PID"
        ),
        inverseJoinColumns = @JoinColumn(
                name = "TASK_ID",
                referencedColumnName = "TID"
        )
)
@OneToMany
private List<Task> tasks;

The resulting database would have become:

Finally, if you want to create a schema for a many-to-many association, using a join table is the only available solution.

Using the browser's parser is the probably the best bet in current browsers. The following will work, with the following caveats:

• Your HTML is valid within a <div> element. HTML contained within <body> or <html> or <head> tags is not valid within a <div> and may therefore not be parsed correctly.
• textContent (the DOM standard property) and innerText (non-standard) properties are not identical. For example, textContent will include text within a <script> element while innerText will not (in most browsers). This only affects IE <=8, which is the only major browser not to support textContent.
• The HTML does not contain <script> elements.
• The HTML is not null
• The HTML comes from a trusted source. Using this with arbitrary HTML allows arbitrary untrusted JavaScript to be executed. This example is from a comment by Mike Samuel on the duplicate question: <img onerror='alert(\"could run arbitrary JS here\")' src=bogus>

Code:

var html = "<p>Some HTML</p>";
var div = document.createElement("div");
div.innerHTML = html;
var text = div.textContent || div.innerText || "";

With PowerShell 5.1 in Windows 10 you can use:

Get-SmbMapping | Remove-SmbMapping -Confirm:$false

You can get all your fingerprints from https://console.developers.google.com/projectselector/apis/credentials
And use this Kotlin code to convert it to keyhash:

fun main(args: Array<String>) {
    listOf("<your_production_sha1_fingerprint>",
            "<your_debug1_sha1_fingerprint>",
            "<your_debug2_sha1_fingerprint>")
            .map { it.split(":") }
            .map { it.map { it.toInt(16).toByte() }.toByteArray() }
            .map { String(Base64.getEncoder().encode(it)) }
            .forEach { println(it) }
}

You can use the function subset inside ggplot2. Try this

library(ggplot2)

data("iris")
iris$Sepal.Length[5:10] <- NA # create some NAs for this example

ggplot(data=subset(iris, !is.na(Sepal.Length)), aes(x=Sepal.Length)) + 
geom_bar(stat="bin")

Unicode is a fairly complex standard. Don’t be too afraid, but be prepared for some work! [2]

Because a credible resource is always needed, but the official report is massive, I suggest reading the following:

1. The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) An introduction by Joel Spolsky, Stack Exchange CEO.
2. To the BMP and beyond! A tutorial by Eric Muller, Technical Director then, Vice President later, at The Unicode Consortium. (first 20 slides and you are done)

A brief explanation:

Computers read bytes and people read characters, so we use encoding standards to map characters to bytes. ASCII was the first widely used standard, but covers only Latin (7 bits/character can represent 128 different characters). Unicode is a standard with the goal to cover all possible characters in the world (can hold up to 1,114,112 characters, meaning 21 bits/character max. Current Unicode 8.0 specifies 120,737 characters in total, and that's all).

The main difference is that an ASCII character can fit to a byte (8 bits), but most Unicode characters cannot. So encoding forms/schemes (like UTF-8 and UTF-16) are used, and the character model goes like this:

Every character holds an enumerated position from 0 to 1,114,111 (hex: 0-10FFFF) called code point.
An encoding form maps a code point to a code unit sequence. A code unit is the way you want characters to be organized in memory, 8-bit units, 16-bit units and so on. UTF-8 uses 1 to 4 units of 8 bits, and UTF-16 uses 1 or 2 units of 16 bits, to cover the entire Unicode of 21 bits max. Units use prefixes so that character boundaries can be spotted, and more units mean more prefixes that occupy bits. So, although UTF-8 uses 1 byte for the Latin script it needs 3 bytes for later scripts inside Basic Multilingual Plane, while UTF-16 uses 2 bytes for all these. And that's their main difference.
Lastly, an encoding scheme (like UTF-16BE or UTF-16LE) maps (serializes) a code unit sequence to a byte sequence.

character: p
code point: U+03C0
encoding forms (code units):
      UTF-8: CF 80
      UTF-16: 03C0
encoding schemes (bytes):
      UTF-8: CF 80
      UTF-16BE: 03 C0
      UTF-16LE: C0 03

Tip: a hex digit represents 4 bits, so a two-digit hex number represents a byte
Also take a look at Plane maps in Wikipedia to get a feeling of the character set layout

Your convention seems to be reasonable. If I were searching for your framework in the Maven repo, I would look for awesome-inhouse-framework-x.y.jar in com.mycompany.awesomeinhouseframework group directory. And I would find it there according to your convention.

Two simple rules work for me:

• reverse-domain-packages for groupId (since such are quite unique) with all the constrains regarding Java packages names
• project name as artifactId (keeping in mind that it should be jar-name friendly i.e. not contain characters that maybe invalid for a file name or just look weird)

you can also use MEDIUMBLOB/LONGBLOB or MEDIUMTEXT/LONGTEXT

A BLOB type in MySQL can store up to 65,534 bytes, if you try to store more than this much data MySQL will truncate the data. MEDIUMBLOB can store up to 16,777,213 bytes, and LONGBLOB can store up to 4,294,967,292 bytes.

The real answer is to use:

Color.parseColor(myPassedColor) in Android, myPassedColor being the hex value like #000 or #000000 or #00000000.

However, this function does not support shorthand hex values such as #000.

You can deploy an images folder as a separate webapp and define the location of that folder to be anywhere in the file system.

Create a Context element in an XML file in the directory $CATALINA_HOME/conf/[enginename]/[hostname]/ where enginename might be 'Catalina' and hostname might be 'localhost'.

Name the file based on the path URL you want the images to be viewed from, so if your webapp has path 'blog', you might name the XML file blog#images.xml and so that your images would be visible at example.com/blog/images/

The content of the XML file should be <Context docBase="/filesystem/path/to/images"/>

Be careful not to undeploy this webapp, as that could delete all your images!

Almost all answers I searched for this issue say that Python on Windows comes with tkinter and tcl already installed, and I had no luck trying to download or install them using pip, or actviestate.com site. I eventually found that when I was installing python using the binary installer, I had unchecked the module related to TCL and tkinter. So, I ran the binary installer again and chose to modify my python version by this time selecting this option. No need to do anything manually then. If you go to your python terminal, then the following commands should show you version of tkinter installed with your Python:

import tkinter
import _tkinter
tkinter._test()

There is a whole page in the MATLAB documentation dedicated to this topic: Array vs. Matrix Operations. The gist of it is below:

MATLAB® has two different types of arithmetic operations: array operations and matrix operations. You can use these arithmetic operations to perform numeric computations, for example, adding two numbers, raising the elements of an array to a given power, or multiplying two matrices.

Matrix operations follow the rules of linear algebra. By contrast, array operations execute element by element operations and support multidimensional arrays. The period character (.) distinguishes the array operations from the matrix operations. However, since the matrix and array operations are the same for addition and subtraction, the character pairs .+ and .- are unnecessary.

As simple as this...

setSize(220, 400);
setLocationRelativeTo(null);  

or if you are using a frame then set the frame to

frame.setSize(220, 400);
frame.setLocationRelativeTo(null);  

For clarification, from the docs:

If the component is null, or the GraphicsConfiguration associated with this component is null, the window is placed in the center of the screen.

You may check if you have the directory where are the packages of Python (in my machine, this dir is C:\Python27\lib\site-packages) in the Path variable on Windows. If Python's path environment variable does not have this directory, you will not find the packages.

From the Notes of Fred Swartz (fredosaurus) :

There are two types of methods.

• Instance methods are associated with an object and use the instance variables of that object. This is the default.

• Static methods use no instance variables of any object of the class they are defined in. If you define a method to be static, you will be given a rude message by the compiler if you try to access any instance variables. You can access static variables, but except for constants, this is unusual. Static methods typically take all they data from parameters and compute something from those parameters, with no reference to variables. This is typical of methods which do some kind of generic calculation. A good example of this are the many utility methods in the predefined Math class.

Qualifying a static call

From outside the defining class, an instance method is called by prefixing it with an object, which is then passed as an implicit parameter to the instance method, eg, inputTF.setText("");

A static method is called by prefixing it with a class name, eg, Math.max(i,j);. Curiously, it can also be qualified with an object, which will be ignored, but the class of the object will be used.

Example

Here is a typical static method:

class MyUtils {
    . . .
    //================================================= mean
    public static double mean(int[] p) {
        int sum = 0;  // sum of all the elements
        for (int i=0; i<p.length; i++) {
            sum += p[i];
        }
        return ((double)sum) / p.length;
    }//endmethod mean
    . . .
}

The only data this method uses or changes is from parameters (or local variables of course).

Why declare a method static

The above mean() method would work just as well if it wasn't declared static, as long as it was called from within the same class. If called from outside the class and it wasn't declared static, it would have to be qualified (uselessly) with an object. Even when used within the class, there are good reasons to define a method as static when it could be.

• Documentation. Anyone seeing that a method is static will know how to call it (see below). Similarly, any programmer looking at the code will know that a static method can't interact with instance variables, which makes reading and debugging easier.
• Efficiency. A compiler will usually produce slightly more efficient code because no implicit object parameter has to be passed to the method.

Calling static methods

There are two cases.

Called from within the same class

Just write the static method name. Eg:

// Called from inside the MyUtils class
double avgAtt = mean(attendance);

Called from outside the class

If a method (static or instance) is called from another class, something must be given before the method name to specify the class where the method is defined. For instance methods, this is the object that the method will access. For static methods, the class name should be specified. Eg:

// Called from outside the MyUtils class.
double avgAtt = MyUtils.mean(attendance); 

If an object is specified before it, the object value will be ignored and the the class of the object will be used.

Accessing static variables

Altho a static method can't access instance variables, it can access static variables. A common use of static variables is to define "constants". Examples from the Java library are Math.PI or Color.RED. They are qualified with the class name, so you know they are static. Any method, static or not, can access static variables. Instance variables can be accessed only by instance methods.

Alternate Call

What's a little peculiar, and not recommended, is that an object of a class may be used instead of the class name to access static methods. This is bad because it creates the impression that some instance variables in the object are used, but this isn't the case.

This worked for me:

//Button method example
 @IBAction func LogOutPressed(_ sender: UIBarButtonItem) {

        do {
            try Auth.auth().signOut()
            navigationController?.popToRootViewController(animated: true)

        } catch let signOutError as NSError {
          print ("Error signing out: %@", signOutError)
        }


    }

The problem is that you thought your jsonString is a dictionary. It's not.

It's an array of dictionaries. In raw json strings, arrays begin with [ and dictionaries begin with {.

I used your json string with below code :

let string = "[{\"form_id\":3465,\"canonical_name\":\"df_SAWERQ\",\"form_name\":\"Activity 4 with Images\",\"form_desc\":null}]"
let data = string.data(using: .utf8)!
do {
    if let jsonArray = try JSONSerialization.jsonObject(with: data, options : .allowFragments) as? [Dictionary<String,Any>]
    {
       print(jsonArray) // use the json here     
    } else {
        print("bad json")
    }
} catch let error as NSError {
    print(error)
}

and I am getting the output :

[["form_desc": <null>, "form_name": Activity 4 with Images, "canonical_name": df_SAWERQ, "form_id": 3465]]

The very concept of a "proper" way to do anything, apart from using CPAN, is non existent in Perl.

Anyways those are numeric operators, you should use

if($foo eq "")

or

if(length($foo) == 0)

You may try Navicat. It used to have a free "Lite" version whih is unfortunately not available any more. The pro version supports several important DB engines, not only SQLite. I am currently using the 30-day free eval version.

Thanks to @donut I managed to get the never expiring access token in JavaScript.

// Initialize exchange
fetch('https://graph.facebook.com/v3.2/oauth/access_token?grant_type=fb_exchange_token&client_id={client_id}&client_secret={client_secret}&fb_exchange_token={short_lived_token}')
.then((data) => {
    return data.json();
})
.then((json) => {
    // Get the user data
    fetch(`https://graph.facebook.com/v3.2/me?access_token=${json.access_token}`)
    .then((data) => {
        return data.json();
    })
    .then((userData) => {
        // Get the page token
        fetch(`https://graph.facebook.com/v3.2/${userData.id}/accounts?access_token=${json.access_token}`)
        .then((data) => {
            return data.json();
        })
        .then((pageToken) => {
            // Save the access token somewhere
            // You'll need it at later point
        })
        .catch((err) => console.error(err))
    })
    .catch((err) => console.error(err))
})
.catch((err) => {
    console.error(err);
})

and then I used the saved access token like this

fetch('https://graph.facebook.com/v3.2/{page_id}?fields=fan_count&access_token={token_from_the_data_array}')
.then((data) => {
    return data.json();
})
.then((json) => {
    // Do stuff
})
.catch((err) => console.error(err))

I hope that someone can trim this code because it's kinda messy but it was the only way I could think of.

There have multiple solusions to convert list to a collection

Solution 1

List<Contact> CONTACTS = new ArrayList<String>();
// fill CONTACTS
Collection<Contact> c = CONTACTS;

Solution 2

private static final Collection<String> c = new ArrayList<String>(
                                                Arrays.asList("a", "b", "c"));

Solution 3

private static final Collection<Contact> = new ArrayList<Contact>(
                       Arrays.asList(new Contact("text1", "name1")
                                     new Contact("text2", "name2")));

Solution 4

List<? extends Contact> col = new ArrayList<Contact>(CONTACTS);

Those are optional settings. Leave it set as Unknown and you should be good.

Edit: If "unknown" is no longer an option, try leaving everything in that section blank.

I was receiving this error because I happened to be opening a website project over a mapped network drive z:\folder instead of connecting via a UNC path \\server\path\folder. Once I opened the project from the UNC path it built just fine.

In Javascript, for example, functions are treated as the same mixed type as everything else (int, string, float, bool). As such, you can create functions on the fly, assign them to things, and call them back later. It's useful but, not something you want to over use or you'll confuse everyone who has to maintain your code after you...

This is some code I was playing with to see how deep this rabbit hole goes:

var x = new Object;
x.thingy = new Array();
x.thingy[0] = function(){ return function(){ return function(){ alert('index 0 pressed'); }; }; }
x.thingy[1] = function(){ return function(){ return function(){ alert('index 1 pressed'); }; }; }
x.thingy[2] = function(){ return function(){ return function(){ alert('index 2 pressed'); }; }; }

for(var i=0 ;i<3; i++)
    x.thingy[i]()()();

if you want to pass POST variables, you have to use a HTML Form:

<form action="http://localhost:8080/login" method="POST" target="_blank">
    <input type="text" name="cid" />
    <input type="password" name="pwd" />
    <input type="submit" value="open" />
</form>

or:

if you want to pass GET variables in an URL, write them without single-quotes:

http://yourdomain.com/login?cid=username&pwd=password

here's how to create the string above with javascrpt variables:

myu = document.getElementById('cid').value;
myp = document.getElementById('pwd').value;
window.open("http://localhost:8080/login?cid="+ myu +"&pwd="+ myp ,"MyTargetWindowName");

in the document with that url, you have to read the GET parameters. if it's in php, use:

$_GET['username']

be aware: to transmit passwords that way is a big security leak!

Just a slight correction on the others in SQL Server (schema prefix is becoming more important!):

SELECT name
  FROM sys.columns 
  WHERE [object_id] = OBJECT_ID('dbo.tablename');

You can use

gem uninstall <gem-name>

Since Spark 1.5 you can use a number of date processing functions:

• pyspark.sql.functions.year
• pyspark.sql.functions.month
• pyspark.sql.functions.dayofmonth
• pyspark.sql.functions.dayofweek()
• pyspark.sql.functions.dayofyear
• pyspark.sql.functions.weekofyear()

import datetime
from pyspark.sql.functions import year, month, dayofmonth

elevDF = sc.parallelize([
    (datetime.datetime(1984, 1, 1, 0, 0), 1, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 2, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 3, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 4, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 5, 638.55)
]).toDF(["date", "hour", "value"])

elevDF.select(
    year("date").alias('year'), 
    month("date").alias('month'), 
    dayofmonth("date").alias('day')
).show()
# +----+-----+---+
# |year|month|day|
# +----+-----+---+
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# +----+-----+---+

You can use simple map as with any other RDD:

elevDF = sqlContext.createDataFrame(sc.parallelize([
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=1, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=2, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=3, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=4, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=5, value=638.55)]))

(elevDF
 .map(lambda (date, hour, value): (date.year, date.month, date.day))
 .collect())

and the result is:

[(1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1)]

Btw: datetime.datetime stores an hour anyway so keeping it separately seems to be a waste of memory.

Do what Kelly said...

BUT. Instead of having the input positioned absolute and top -20px (just hiding it off the page), make the input box hidden.

example:

<input type="checkbox" hidden> 

Works better and can put it anywhere on the page.

Yes, I wrote a little groovy script which does the trick You should add a 'Dynamic Choice Parameter' to your job and customize the following groovy script to your needs :

#!/usr/bin/groovy

def gitURL = "git repo url"
def command = "git ls-remote --heads --tags ${gitURL}"

def proc = command.execute()
proc.waitFor()              

if ( proc.exitValue() != 0 ) {
   println "Error, ${proc.err.text}"
   System.exit(-1)
}

def text = proc.in.text
# put your version string match
def match = /<REGEX>/
def tags = []

text.eachMatch(match) { tags.push(it[1]) }
tags.unique()
tags.sort( { a, b ->
         def a1 = a.tokenize('._-')
         def b1 = b.tokenize('._-')
         try {
            for (i in 1..<[a1.size(), b1.size()].min()) { 
                 if (a1[i].toInteger() != b1[i].toInteger()) return a1[i].toInteger() <=> b1[i].toInteger()
            }
            return 1
         } catch (e) {
            return -1;
         }
} )
tags.reverse()

I my case the version string was in the following format X.X.X.X and could have user branches in the format X.X.X-username ,etc... So I had to write my own sort function. This was my first groovy script so if there are better ways of doing thing I would like to know.

You can use base_path() to get the base of your application - and then just add your public folder to that:

$path = base_path().'/public';
return File::put($path , $data)

Note: Be very careful about allowing people to upload files into your root of public_html. If they upload their own index.php file, they will take over your site.

I didn't understand how the accepted answer answers the actual question of how to run any commands on the server after sshpass is given from within the bash script file. For that reason, I'm providing an answer.

After your provided script commands, execute additional commands like below:

sshpass -p 'password' ssh user@host "ls; whois google.com;" #or whichever commands you would like to use, for multiple commands provide a semicolon ; after the command

In your script:

#! /bin/bash

sshpass -p 'password' ssh user@host "ls; whois google.com;"

With jQuery you can use

$('#main-div .specific-class').length

otherwise in VanillaJS (from IE8 included) you may use

document.querySelectorAll('#main-div .specific-class').length;

I resolved the issue by converting the source feed from http://www.news18.com/rss/politics.xml to https://www.news18.com/rss/politics.xml

with http below code was creating an empty file which was causing the issue down the line

    String feedUrl = "https://www.news18.com/rss/politics.xml"; 
    File feedXmlFile = null;

    try {
    feedXmlFile =new File("C://opinionpoll/newsFeed.xml");
    FileUtils.copyURLToFile(new URL(feedUrl),feedXmlFile);


          DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
          DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
          Document doc = dBuilder.parse(feedXmlFile);

if ([ $NUM1 == 1 ] || [ $NUM2 == 1 ]) && [ -z "$STR" ]
then
    echo STR is empty but should have a value.

Try providing the proxy details as parameters

sbt compile -Dhttps.proxyHost=localhost -Dhttps.proxyPort=port -Dhttp.proxyHost=localhost -Dhttp.proxyPort=port

If that is not working then try with JAVA_OPTS (non windows)

export JAVA_OPTS = "-Dhttps.proxyHost=localhost -Dhttps.proxyPort=port -Dhttp.proxyHost=localhost -Dhttp.proxyPort=port"

sbt compile

or (windows)

set JAVA_OPTS = "-Dhttps.proxyHost=localhost -Dhttps.proxyPort=port -Dhttp.proxyHost=localhost -Dhttp.proxyPort=port"
sbt compile

if nothing works then set SBT_OPTS

(non windows)

export SBT_OPTS = "-Dhttps.proxyHost=localhost -Dhttps.proxyPort=port -Dhttp.proxyHost=localhost -Dhttp.proxyPort=port"'
sbt compile

or (windows)

set SBT_OPTS = "-Dhttps.proxyHost=localhost -Dhttps.proxyPort=port -Dhttp.proxyHost=localhost -Dhttp.proxyPort=port"
sbt compile

I generally use array split because it's easier simple syntax and scales better with more than 2 partitions.

import numpy as np
partitions = 2
dfs = np.array_split(df, partitions)

np.split(df, [100,200,300], axis=0] wants explicit index numbers which may or may not be desirable.

For those who could not get DATEADD to work, try this instead: ( NOW( ) - INTERVAL 1 MONTH )

You can also have a look at FLTK (C++ and not plain C though)

FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X. FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL® and its built-in GLUT emulation.

FLTK is designed to be small and modular enough to be statically linked, but works fine as a shared library. FLTK also includes an excellent UI builder called FLUID that can be used to create applications in minutes.

Here are some quickstart screencasts

[Happy New Year!]

If your rename doesn't support -N, you can do something like this:

ls -1 --color=never -c | xargs rename -n 's/.*/our $i; sprintf("%04d.jpg", $i++)/e'

Edit To start with a given number, you can use the (somewhat ugly-looking) code below, just replace 123 with the number you want:

ls -1 --color=never  -c | xargs rename -n 's/.*/our $i; if(!$i) { $i=123; } sprintf("%04d.jpg", $i++)/e'

This lists files in order by creation time (newest first, add -r to ls to reverse sort), then sends this list of files to rename. Rename uses perl code in the regex to format and increment counter.

However, if you're dealing with JPEG images with EXIF information, I'd recommend exiftool

This is from the exiftool documentation, under "Renaming Examples"

   exiftool '-FileName<CreateDate' -d %Y%m%d_%H%M%S%%-c.%%e dir

   Rename all images in "dir" according to the "CreateDate" date and time, adding a copy number with leading '-' if the file already exists ("%-c"), and
   preserving the original file extension (%e).  Note the extra '%' necessary to escape the filename codes (%c and %e) in the date format string.

You can't unless you're using some kind of extended CSS such as SASS. However it is very reasonable to apply those two extra classes to .someDiv.

If .someDiv is unique I would also choose to give it an id and referencing it in css using the id.

I would handle it like so:

$(document).ready(function() {
   $('input[type="radio"]').click(function() {
       if($(this).attr('id') == 'watch-me') {
            $('#show-me').show();           
       }

       else {
            $('#show-me').hide();   
       }
   });
});

You can subclass HandleErrorAttribute and override its OnException member (no need to copy) so that it logs the exception with ELMAH and only if the base implementation handles it. The minimal amount of code you need is as follows:

using System.Web.Mvc;
using Elmah;

public class HandleErrorAttribute : System.Web.Mvc.HandleErrorAttribute
{
    public override void OnException(ExceptionContext context)
    {
        base.OnException(context);
        if (!context.ExceptionHandled) 
            return;
        var httpContext = context.HttpContext.ApplicationInstance.Context;
        var signal = ErrorSignal.FromContext(httpContext);
        signal.Raise(context.Exception, httpContext);
    }
}

The base implementation is invoked first, giving it a chance to mark the exception as being handled. Only then is the exception signaled. The above code is simple and may cause issues if used in an environment where the HttpContext may not be available, such as testing. As a result, you will want code that is that is more defensive (at the cost of being slightly longer):

using System.Web;
using System.Web.Mvc;
using Elmah;

public class HandleErrorAttribute : System.Web.Mvc.HandleErrorAttribute
{
    public override void OnException(ExceptionContext context)
    {
        base.OnException(context);
        if (!context.ExceptionHandled       // if unhandled, will be logged anyhow
            || TryRaiseErrorSignal(context) // prefer signaling, if possible
            || IsFiltered(context))         // filtered?
            return;

        LogException(context);
    }

    private static bool TryRaiseErrorSignal(ExceptionContext context)
    {
        var httpContext = GetHttpContextImpl(context.HttpContext);
        if (httpContext == null)
            return false;
        var signal = ErrorSignal.FromContext(httpContext);
        if (signal == null)
            return false;
        signal.Raise(context.Exception, httpContext);
        return true;
    }

    private static bool IsFiltered(ExceptionContext context)
    {
        var config = context.HttpContext.GetSection("elmah/errorFilter")
                        as ErrorFilterConfiguration;

        if (config == null)
            return false;

        var testContext = new ErrorFilterModule.AssertionHelperContext(
                              context.Exception, 
                              GetHttpContextImpl(context.HttpContext));
        return config.Assertion.Test(testContext);
    }

    private static void LogException(ExceptionContext context)
    {
        var httpContext = GetHttpContextImpl(context.HttpContext);
        var error = new Error(context.Exception, httpContext);
        ErrorLog.GetDefault(httpContext).Log(error);
    }

    private static HttpContext GetHttpContextImpl(HttpContextBase context)
    {
        return context.ApplicationInstance.Context;
    }
}

This second version will try to use error signaling from ELMAH first, which involves the fully configured pipeline like logging, mailing, filtering and what have you. Failing that, it attempts to see whether the error should be filtered. If not, the error is simply logged. This implementation does not handle mail notifications. If the exception can be signaled then a mail will be sent if configured to do so.

You may also have to take care that if multiple HandleErrorAttribute instances are in effect then duplicate logging does not occur, but the above two examples should get your started.

you can also use pure js to accomplish this like the old ways with jquery

try this if you want a simple way

 document.getElementById("myID").classList.add("show-example");

The 'Compat' library now also supports the generateViewId() method for API levels prior 17.

Just make sure to use a version of the Compat library that is 27.1.0+

For example, in your build.gradle file, put :

implementation 'com.android.support:appcompat-v7:27.1.1

Then you can simply use the generateViewId() from the ViewCompat class instead of the View class as follow:

//Will assign a unique ID myView.id = ViewCompat.generateViewId()

Happy coding !

A quick solution that might help someone :

Add this line as value for start ng serve --host 0.0.0.0 --disable-host-check in your package.json

ex:

{
"ng": "ng",
"start": "ng serve --host 0.0.0.0 --disable-host-check",
"build": "ng build",
}

And then simply do start or npm run start

you will be able to access your project from other local IPs.

Indeed, calling zipWithIndex on a collection will traverse it and also create a new collection for the pairs. To avoid this, you can just call zipWithIndex on the iterator for the collection. This will just return a new iterator that keeps track of the index while iterating, so without creating an extra collection or additional traversing.

This is how scala.collection.Iterator.zipWithIndex is currently implemented in 2.10.3:

  def zipWithIndex: Iterator[(A, Int)] = new AbstractIterator[(A, Int)] {
    var idx = 0
    def hasNext = self.hasNext
    def next = {
      val ret = (self.next, idx)
      idx += 1
      ret
    }
  }

This should even be a bit more efficient than creating a view on the collection.

I know that this is an old answered question, but I use datetime.utcfromtimestamp() for this. It takes the number of seconds and returns a datetime that can be formatted like any other datetime.

duration = datetime.utcfromtimestamp(end - begin)
print duration.strftime('%H:%M')

As long as you stay in the legal ranges for the time parts this should work, i.e. it doesn't return 1234:35 as hours are <= 23.

I had the same problem several times - just rebooting solves this.

In my case I was migrating from 9.5 to 9.6. So to restore a database, I was doing :

sudo -u postgres psql -d databse -f dump.sql

Of course it was executing on the old postgreSQL database where there are datas! If your new instance is on port 5433, the correct way is :

sudo -u postgres psql -d databse -f dump.sql -p 5433

It's used to contain data which could otherwise be seen as xml because it contains certain characters.

This way the data inside will be displayed, but not interpreted.

You could try writing to stderr, rather than stdout.

fprintf(stderr, "Hello, please enter your age\n");

You should also have a look at this relevant thread.

There are many ways to perform your task, but the most elegant are, I believe, using css. Here are basic steps

1. Listening option selection event, biding adding/removing some class to container action, which contains all divs you are interested in (for example, body)
2. Adding styles for hiding all divs except one.
3. Well done, sir.

This works pretty well if there a few divs, since more elements you want to toggle, more css rules should be written. Here is more general solution, binding action, base on following steps: 1. find all elements using some selector (usually it looks like '.menu-container .menu-item') 2. find one of found elements, which is current visible, hide it 3. make visible another element, the one you desire to be visible under new circumstances.

javascript it a rather timtoady language )

HTML:

  <input id="search" size="10" />

jQuery:

$("#search").focus();

One can access each element of an array separately using the following code:

Object o=...;
if ( o.getClass().isArray() ) {
    for(int i=0; i<Array.getLength(o); i++){
        System.out.println(Array.get(o, i));
    }
}

Notice that it is unnecessary to know what kind of underlying array it is, as this will work for any array.

The download attribute is not supported in IE (see http://caniuse.com/#search=download%20attribute).

That suggests the download attribute is only supported by firefox, chrome, opera and the latest version of blackberry's browser.

For other browsers you'll need to use more traditional methods to force download. That is server side code is necessary to set an appropriate Content-Type and Content-Disposition header to tell (or trick depending on your point of view) the browser to download the item. Headers should look like this:

Content-Type: application/octet-stream
Content-Disposition: attachment;filename=\"filename.xxx\"

(thanks to antyrat for the copy and paste of the headers)

I'm adding this answer because it solved a related problem that I was having with the same error message.

Problem: I had installed cygwin under Windows and was getting this error: Pseudo-terminal will not be allocated because stdin is not a terminal

Resolution: It turns out that I had not installed the openssh client program and utilities. Because of that cygwin was using the Windows implementation of ssh, not the cygwin version. The solution was to install the openssh cygwin package.

Since the question is how to replace ALL whitespaces

UPDATE `table` 
SET `col_name` = REPLACE
(REPLACE(REPLACE(`col_name`, ' ', ''), '\t', ''), '\n', '');

You need to access a geocoding service (i.e. from Google), there is no simple formula to transfer addresses to geo coordinates.

Try this:

Process.Start("Location Of File.exe");

(Make sure you use the System.Diagnostics library)

IF(compliment IN('set','Y',1), 'Y', 'N') AS customer_compliment

Will do the job as Buttle Butkus suggested.

What you are doing right now is you are adding . on the string and not concatenating. It should be,

$result = mysqli_query($con,"SELECT `note` FROM `glogin_users` WHERE email = '".$email."'");

or simply

$result = mysqli_query($con,"SELECT `note` FROM `glogin_users` WHERE email = '$email'");

Keep it simple. Use both onKeyPress() and onKeyUp():

<input id="edValue" type="text" onKeyPress="edValueKeyPress()" onKeyUp="edValueKeyPress()">

This takes care of getting the most updated string value (after key up) and also updates if the user holds down a key.

To answer Janus Troelsen comment

Use UNIX_TIMESTAMP instead of TIMESTAMP

SELECT from_unixtime( UNIX_TIMESTAMP(  "2011-12-01 22:01:23.048" ) )

The TIMESTAMP function returns a Date or a DateTime and not a timestamp, while UNIX_TIMESTAMP returns a unix timestamp

First, you need to understand the difference between window and document. The window object is a top level client side object. There is nothing above the window object. JavaScript is an object orientated language. You start with an object and apply methods to its properties or the properties of its object groups. For example, the document object is an object of the window object. To change the document's background color, you'd set the document's bgcolor property.

window.document.bgcolor = "red" 

To answer your question, There is no difference in the end result between window and document scrollTop. Both will give the same output.

Check working example at http://jsfiddle.net/7VRvj/6/

In general use document mainly to register events and use window to do things like scroll, scrollTop, and resize.

Abstract classes are classes that contain one or more abstract methods. An abstract method is a method that is declared, but contains no implementation. Abstract classes may not be instantiated, and require subclasses to provide implementations for the abstract methods.

1. Can not instantiate abstract class: Classes defined as abstract may not be instantiated, and any class that contains at least one abstract method must also be abstract.

Example below :

abstract class AbstractClass
{

    abstract protected function getValue();
    abstract protected function prefixValue($prefix);


    public function printOut() {
        echo "Hello how are you?";
    }
}

$obj=new AbstractClass();
$obj->printOut();
//Fatal error: Cannot instantiate abstract class AbstractClass

2. Any class that contains at least one abstract method must also be abstract: Abstract class can have abstract and non-abstract methods, but it must contain at least one abstract method. If a class has at least one abstract method, then the class must be declared abstract.

Note: Traits support the use of abstract methods in order to impose requirements upon the exhibiting class.

Example below :

class Non_Abstract_Class
{
   abstract protected function getValue();

    public function printOut() {
        echo "Hello how are you?";
    }
}

$obj=new Non_Abstract_Class();
$obj->printOut();
//Fatal error: Class Non_Abstract_Class contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Non_Abstract_Class::getValue)

3. An abstract method can not contain body: Methods defined as abstract simply declare the method's signature - they cannot define the implementation. But a non-abstract method can define the implementation.

abstract class AbstractClass
{
   abstract protected function getValue(){
   return "Hello how are you?";
   }

    public function printOut() {
        echo $this->getValue() . "\n";
    }
}

class ConcreteClass1 extends AbstractClass
{
    protected function getValue() {
        return "ConcreteClass1";
    }

    public function prefixValue($prefix) {
        return "{$prefix}ConcreteClass1";
    }
}

$class1 = new ConcreteClass1;
$class1->printOut();
echo $class1->prefixValue('FOO_') ."\n";
//Fatal error: Abstract function AbstractClass::getValue() cannot contain body

4. When inheriting from an abstract class, all methods marked abstract in the parent's class declaration must be defined by the child :If you inherit an abstract class you have to provide implementations to all the abstract methods in it.

abstract class AbstractClass
{
    // Force Extending class to define this method
    abstract protected function getValue();

    // Common method
    public function printOut() {
        print $this->getValue() . "<br/>";
    }
}

class ConcreteClass1 extends AbstractClass
{
    public function printOut() {
        echo "dhairya";
    }

}
$class1 = new ConcreteClass1;
$class1->printOut();
//Fatal error: Class ConcreteClass1 contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (AbstractClass::getValue)

5. Same (or a less restricted) visibility:When inheriting from an abstract class, all methods marked abstract in the parent's class declaration must be defined by the child; additionally, these methods must be defined with the same (or a less restricted) visibility. For example, if the abstract method is defined as protected, the function implementation must be defined as either protected or public, but not private.

Note that abstract method should not be private.

abstract class AbstractClass
{

    abstract public function getValue();
    abstract protected function prefixValue($prefix);

        public function printOut() {
        print $this->getValue();
    }
}

class ConcreteClass1 extends AbstractClass
{
    protected function getValue() {
        return "ConcreteClass1";
    }

    public function prefixValue($prefix) {
        return "{$prefix}ConcreteClass1";
    }
}
$class1 = new ConcreteClass1;
$class1->printOut();
echo $class1->prefixValue('FOO_') ."<br/>";
//Fatal error: Access level to ConcreteClass1::getValue() must be public (as in class AbstractClass)

6. Signatures of the abstract methods must match:When inheriting from an abstract class, all methods marked abstract in the parent's class declaration must be defined by the child;the signatures of the methods must match, i.e. the type hints and the number of required arguments must be the same. For example, if the child class defines an optional argument, where the abstract method's signature does not, there is no conflict in the signature.

abstract class AbstractClass
{

    abstract protected function prefixName($name);

}

class ConcreteClass extends AbstractClass
{


    public function prefixName($name, $separator = ".") {
        if ($name == "Pacman") {
            $prefix = "Mr";
        } elseif ($name == "Pacwoman") {
            $prefix = "Mrs";
        } else {
            $prefix = "";
        }
        return "{$prefix}{$separator} {$name}";
    }
}

$class = new ConcreteClass;
echo $class->prefixName("Pacman"), "<br/>";
echo $class->prefixName("Pacwoman"), "<br/>";
//output: Mr. Pacman
//        Mrs. Pacwoman

7. Abstract class doesn't support multiple inheritance:Abstract class can extends another abstract class,Abstract class can provide the implementation of interface.But it doesn't support multiple inheritance.

interface MyInterface{
    public function foo();

Note: Please note order or positioning of the classes in your code can affect the interpreter and can cause a Fatal error. So, when using multiple levels of abstraction, be careful of the positioning of the classes within the source code.

below example will cause Fatal error: Class 'horse' not found

class cart extends horse {
    public function get_breed() { return "Wood"; }
}

abstract class horse extends animal {
    public function get_breed() { return "Jersey"; }
}

abstract class animal {
    public abstract function get_breed();
}

$cart = new cart();
print($cart->get_breed());

Had exactly the same problem as UseR (original question), I'm also using windows 7. I tried all proposed solutions and they didn't work.

I resolved the problem doing as follows:

1. Using RStudio instead of R console.

2. Actualising the version of R (from 3.1.0 to 3.1.1) so that the library RCurl runs OK on it. (I'm using now R3.1.1 32bit although my system is 64bit).

3. I typed the URL address as https (secure connection) and with / instead of backslashes \\.

4. Setting method = "auto".

It works for me now. You should see the message:

It is not possible to return an array from a C++ function. 8.3.5[dcl.fct]/6:

Functions shall not have a return type of type array or function[...]

Most commonly chosen alternatives are to return a value of class type where that class contains an array, e.g.

struct ArrayHolder
{
    int array[10];
};

ArrayHolder test();

Or to return a pointer to the first element of a statically or dynamically allocated array, the documentation must indicate to the user whether he needs to (and if so how he should) deallocate the array that the returned pointer points to.

E.g.

int* test2()
{
    return new int[10];
}

int* test3()
{
    static int array[10];
    return array;
}

While it is possible to return a reference or a pointer to an array, it's exceedingly rare as it is a more complex syntax with no practical advantage over any of the above methods.

int (&test4())[10]
{
        static int array[10];
        return array;
}

int (*test5())[10]
{
        static int array[10];
        return &array;
}

As already mentioned the C++ way is using stringstreams.

#include <sstream>

string a = "test";
string b = "text.txt";
string c = "text1.txt";

std::stringstream ostr;
ostr << a << " " << b << " > " << c;

Note that you can get the C string from the string stream object like so.

std::string formatted_string = ostr.str();
const char* c_str = formatted_string.c_str();

you need to prevent event's default behaviour as follows.

In html

<a href="" (click)="view($event)">view</a>

In ts file

view(event:Event){
 event.preventDefault();
 //remaining code goes here..
}

if you use ini_set on the fly then you will find here http://php.net/manual/en/ini.core.php the information that e.g. upload_max_filesize and post_max_size is not changeable on the fly (PHP_INI_PERDIR).

Only a php.ini, .htaccess or vhost config change seems to change these variables.

(as per http://java.sun.com/...ex/Pattern.html)

The backslash character ('\') serves to introduce escaped constructs, as defined in the table above, as well as to quote characters that otherwise would be interpreted as unescaped constructs. Thus the expression \\ matches a single backslash and { matches a left brace.

Other examples of usage :

\\ The backslash character<br>
\t The tab character ('\u0009')<br>
\n The newline (line feed) character ('\u000A')<br>
\r The carriage-return character ('\u000D')<br>
\f The form-feed character ('\u000C')<br>
\a The alert (bell) character ('\u0007')<br>
\e The escape character ('\u001B')<br>
\cx The control character corresponding to x <br>

You are missing a comma after

'data': { 'request': "", 'target': 'arrange_url', 'method': 'method_target' }

Also, if you want return_first to hold the result of your anonymous function, you need to make a function call:

var return_first = function () {
    var tmp = null;
    $.ajax({
        'async': false,
        'type': "POST",
        'global': false,
        'dataType': 'html',
        'url': "ajax.php?first",
        'data': { 'request': "", 'target': 'arrange_url', 'method': 'method_target' },
        'success': function (data) {
            tmp = data;
        }
    });
    return tmp;
}();

Note () at the end.

As @stevebot said, do this:

https://<bucket-name>.s3.amazonaws.com/<key>

The one important thing I would like to add is that you either have to make your bucket objects all publicly accessible OR you can add a custom policy to your bucket policy. That custom policy could allow traffic from your network IP range or a different credential.

Simply, create the folder you want to extract Aptana Studio to, and then use this command:

Aptana_Studio_3_Setup_3.6.1.exe /extract:"folder"

This is an annoying Eclipse Bug which seems to bite now and then. See http://dev-answers.blogspot.de/2009/06/eclipse-build-errors-javalangobject.html for a possible solution, otherwise try the following;

• Close the project and reopen it.

• Clean the project (It will rebuild the buildpath hence reconfiguring with the JDK libraries)

  OR

• Delete and Re-import the project and if necessary do the above steps again.

The better cure is to try NetBeans instead of Eclipse :-)

in case files have no extension we can look for file mime type

find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 ~ /audio|video|matroska|mpeg/) print $1 }'

where (audio|video|matroska|mpeg) are mime types regex

&if you want to delete them:

find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 ~ /audio|video|matroska|mpeg/) print $1 }' | while read f ; do
  rm "$f"
done

or delete everything else but those extensions:

find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 !~ /audio|video|matroska|mpeg/) print $1 }' | while read f ; do
  rm "$f"
done

notice the !~ instead of ~

SELECT CONVERT_TZ() will work for that.but its not working for me.

Why, what error do you get?

SELECT CONVERT_TZ(displaytime,'GMT','MET');

should work if your column type is timestamp, or date

http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_convert-tz

Test how this works:

SELECT CONVERT_TZ(a_ad_display.displaytime,'+00:00','+04:00');

Check your timezone-table

SELECT * FROM mysql.time_zone;
SELECT * FROM mysql.time_zone_name;

http://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html

If those tables are empty, you have not initialized your timezone tables. According to link above you can use mysql_tzinfo_to_sql program to load the Time Zone Tables. Please try this

shell> mysql_tzinfo_to_sql /usr/share/zoneinfo

or if not working read more: http://dev.mysql.com/doc/refman/5.5/en/mysql-tzinfo-to-sql.html

It's a mess. MAPI or CDO via a .NET interop DLL is officially unsupported by Microsoft--it will appear to work fine, but there are problems with memory leaks due to their differing memory models. You could use CDOEX, but that only works on the Exchange server itself, not remotely; useless. You could interop with Outlook, but now you've just made a dependency on Outlook; overkill. Finally, you could use Exchange 2003's WebDAV support, but WebDAV is complicated, .NET has poor built-in support for it, and (to add insult to injury) Exchange 2007 nearly completely drops WebDAV support.

What's a guy to do? I ended up using AfterLogic's IMAP component to communicate with my Exchange 2003 server via IMAP, and this ended up working very well. (I normally seek out free or open-source libraries, but I found all of the .NET ones wanting--especially when it comes to some of the quirks of 2003's IMAP implementation--and this one was cheap enough and worked on the first try. I know there are others out there.)

If your organization is on Exchange 2007, however, you're in luck. Exchange 2007 comes with a SOAP-based Web service interface that finally provides a unified, language-independent way of interacting with the Exchange server. If you can make 2007+ a requirement, this is definitely the way to go. (Sadly for me, my company has a "but 2003 isn't broken" policy.)

If you need to bridge both Exchange 2003 and 2007, IMAP or POP3 is definitely the way to go.

Ready-to-use solution that converts all PNG in the current folder to a PDF, inspired by @ilovecomputer's answer:

import glob, PIL.Image
L = [PIL.Image.open(f) for f in glob.glob('*.png')]
L[0].save('out.pdf', "PDF" ,resolution=100.0, save_all=True, append_images=L[1:])

Nothing else than PIL is needed :)

You can also get information from directly connected networking devices, such as network switches with LDWin, a portable and free Windows program published on github:

http://www.sysadmit.com/2016/11/windows-como-saber-la-ip-del-switch-al-que-estoy-conectado.html

LDWin supports the following methods of link discovery: CDP (Cisco Discovery Protocol) and LLDP (Link Layer Discovery Protocol).

You can obtain the model, management IP, VLAN identifier, Port identifier, firmware version, etc.

You can do that using Python 2.

1. Remove request
2. Make that line: from urllib2 import urlopen

You cannot have request in Python 2, you need to have Python 3 or above.

For one-liners, userandom.sample(list_to_be_shuffled, length_of_the_list) with an example:

import random
random.sample(list(range(10)), 10)

outputs: [2, 9, 7, 8, 3, 0, 4, 1, 6, 5]

With Anaconda 4.5+ and Python 3.6+ on Windows use

Ctrl+Z

or

exit()

In some cases, you might have to use

Ctrl+Break

If your computer doesn't have Break key then see here.

Also you can try zenity !

user=$(zenity --entry --text 'Please enter the username:') || exit 1
