You can also use tables to accomplish this, like:

.pdf {
  display: table;
}
.pdf:before {
  display: table-cell;
  vertical-align: middle;
}

Here is an example: https://jsfiddle.net/ar9fadd0/2/

EDIT: You can also use flex to accomplish this:

.pdf {
  display: flex;
}
.pdf:before {
  display: flex;
  align-items: center;
}

Here is an example: https://jsfiddle.net/ctqk0xq1/1/

It might be too late for the answer but we face the same kind of issue on the production. Earlier we have only one RDS and as the number of users increases on the app side, we decided to add Read Replica for it. Read replica works properly on the staging but once we moved to the production we start getting the same error.

So we solve this by enabling hot_standby_feedback property in the Postgres properties. We referred the following link

https://aws.amazon.com/blogs/database/best-practices-for-amazon-rds-postgresql-replication/

I hope it will help.

I think you should go with request parameters but only as long as there isn't an appropriate HTTP header to accomplish what you want to do. The HTTP specification does not explicitly say, that GET can not have a body. However this paper states:

By convention, when GET method is used, all information required to identify the resource is encoded in the URI. There is no convention in HTTP/1.1 for a safe interaction (e.g., retrieval) where the client supplies data to the server in an HTTP entity body rather than in the query part of a URI. This means that for safe operations, URIs may be long.

ping -n 11 -w 1000 127.0.0.1 > nul

Update

Beginner's mistake. Ping doesn't wait 1000 ms before or after an request, but inbetween requests. So to wait 10 seconds, you'll have to do 11 pings to have 10 'gaps' of a second inbetween.

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

It's true that due to it's overhead SOAP is not the best choice for data exchange with mobile devices. However, you might find yourself in situation in which you do not control the format of server output.

So, if you have to stick with SOAP, there is a kSOAP2 library patched for Android here:
http://code.google.com/p/ksoap2-android/

You can use this command:

start /min iexplore http://www.google.com

With the use of /min, it will hit on the URL without opening in the browser.

i am not sure but, I think you can use @ResponseEntity and @ResponseBody and send 2 different one is Success and second is error message like :

@RequestMapping(value ="/book2", produces =MediaType.APPLICATION_JSON_VALUE )
@ResponseBody
Book bookInfo2() {
    Book book = new Book();
    book.setBookName("Ramcharitmanas");
    book.setWriter("TulasiDas");
    return book;
}

@RequestMapping(value ="/book3", produces =MediaType.APPLICATION_JSON_VALUE )
public ResponseEntity<Book> bookInfo3() {
    Book book = new Book();
    book.setBookName("Ramayan");
    book.setWriter("Valmiki");
    return ResponseEntity.accepted().body(book);
}

For more detail refer to this: http://www.concretepage.com/spring-4/spring-4-mvc-jsonp-example-with-rest-responsebody-responseentity

You can also get the value of an item in the jObject like this:

JToken value;
if (json.TryGetValue(key, out value))
{
   DoSomething(value);
}

This is how you would drop the constraint

ALTER TABLE <schema_name, sysname, dbo>.<table_name, sysname, table_name>
   DROP CONSTRAINT <default_constraint_name, sysname, default_constraint_name>
GO

With a script

-- t-sql scriptlet to drop all constraints on a table
DECLARE @database nvarchar(50)
DECLARE @table nvarchar(50)

set @database = 'dotnetnuke'
set @table = 'tabs'

DECLARE @sql nvarchar(255)
WHILE EXISTS(select * from INFORMATION_SCHEMA.TABLE_CONSTRAINTS where constraint_catalog = @database and table_name = @table)
BEGIN
    select    @sql = 'ALTER TABLE ' + @table + ' DROP CONSTRAINT ' + CONSTRAINT_NAME 
    from    INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
    where    constraint_catalog = @database and 
            table_name = @table
    exec    sp_executesql @sql
END

@Mysticial got it. A short is usually 16-bit and will illustrate the answer:

int main()  
{
    unsigned int x = 65529;
    int y = (int) x;
    printf("%d\n", y);

    unsigned short z = 65529;
    short zz = (short)z;
    printf("%d\n", zz);
}

65529
-7
Press any key to continue . . .

So let's look at 65529 decimal. It can be represented as FFF9h in hexadecimal. We can also represent that in binary as:

11111111 11111001

When we declare short zz = 65529;, the compiler interprets 65529 as a signed value. In twos-complement notation, the top bit signifies whether a signed value is positive or negative. In this case, you can see the top bit is a 1, so it is treated as a negative number. That's why it prints out -7.

For an unsigned short, we don't care about sign since it's unsigned. So when we print it out using %d, we use all 16 bits, so it's interpreted as 65529.

A quick fix for this is use [ ] to select the attribute.

function greet(elementId) {
    var inputValue = document.getElementById(elementId)["value"];
    if(inputValue.trim() == "") {
        inputValue = "World";
    }
    document.getElementById("greet").innerText = greeter(inputValue);
}

I just try few methods and find out this solution,
I don't know what's the problem behind your original script.

For reference you may refer to Tomasz Nurkiewicz's post.

I have been puzzled a lot with this problem, since I am relively new in Python. I cannot apply the solution to the code given by the questioned, since it's not self executable. So I bring a very simple code:

from turtle import *

ts = Screen(); tu = Turtle()

def move(x,y):
  print "move()"
  tu.goto(100,100)

ts.listen();
ts.onclick(move)

done()

As you can see, the solution consists in using two (dummy) arguments, even if they are not used either by the function itself or in calling it! It sounds crazy, but I believe there must be a reason for it (hidden from the novice!).

I have tried a lot of other ways ('self' included). It's the only one that works (for me, at least).

I had precisely this problem, but I needed sequential plots to have highly contrasting color. I was also doing plots with a common sub-plot containing reference data, so I wanted the color sequence to be consistently repeatable.

I initially tried simply generating colors randomly, reseeding the RNG before each plot. This worked OK (commented-out in code below), but could generate nearly indistinguishable colors. I wanted highly contrasting colors, ideally sampled from a colormap containing all colors.

I could have as many as 31 data series in a single plot, so I chopped the colormap into that many steps. Then I walked the steps in an order that ensured I wouldn't return to the neighborhood of a given color very soon.

My data is in a highly irregular time series, so I wanted to see the points and the lines, with the point having the 'opposite' color of the line.

Given all the above, it was easiest to generate a dictionary with the relevant parameters for plotting the individual series, then expand it as part of the call.

Here's my code. Perhaps not pretty, but functional.

from matplotlib import cm
cmap = cm.get_cmap('gist_rainbow')  #('hsv') #('nipy_spectral')

max_colors = 31   # Constant, max mumber of series in any plot.  Ideally prime.
color_number = 0  # Variable, incremented for each series.

def restart_colors():
    global color_number
    color_number = 0
    #np.random.seed(1)

def next_color():
    global color_number
    color_number += 1
    #color = tuple(np.random.uniform(0.0, 0.5, 3))
    color = cmap( ((5 * color_number) % max_colors) / max_colors )
    return color

def plot_args():  # Invoked for each plot in a series as: '**(plot_args())'
    mkr = next_color()
    clr = (1 - mkr[0], 1 - mkr[1], 1 - mkr[2], mkr[3])  # Give line inverse of marker color
    return {
        "marker": "o",
        "color": clr,
        "mfc": mkr,
        "mec": mkr,
        "markersize": 0.5,
        "linewidth": 1,
    }

My context is JupyterLab and Pandas, so here's sample plot code:

restart_colors()  # Repeatable color sequence for every plot

fig, axs = plt.subplots(figsize=(15, 8))
plt.title("%s + T-meter"%name)

# Plot reference temperatures:
axs.set_ylabel("°C", rotation=0)
for s in ["T1", "T2", "T3", "T4"]:
    df_tmeter.plot(ax=axs, x="Timestamp", y=s, label="T-meter:%s" % s, **(plot_args()))

# Other series gets their own axis labels
ax2 = axs.twinx()
ax2.set_ylabel(units)

for c in df_uptime_sensors:
    df_uptime[df_uptime["UUID"] == c].plot(
        ax=ax2, x="Timestamp", y=units, label="%s - %s" % (units, c), **(plot_args())
    )

fig.tight_layout()
plt.show()

The resulting plot may not be the best example, but it becomes more relevant when interactively zoomed in.

Just call fig.tight_layout() as you normally would. (pyplot is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)

There shouldn't be a difference between the QtAgg backend and the default backend (or if there is, it's a bug).

E.g.

import matplotlib.pyplot as plt

#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so 
#--    we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

plt.show()

Before Tight Layout

After Tight Layout

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

fig.tight_layout()

plt.show()

I use sftp plugin from my IDE.

1. Install ssh server for your container and allow root access.
2. Run your docker container with -p localport:22
3. Install from your IDE a sftp plugin

Example using sublime sftp plugin: https://www.youtube.com/watch?v=HMfjt_YMru0

You can not "attach" a SASS/SCSS file to an HTML document.

SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.

There are client-side alternatives to SASS that can be compiled in the browser using javascript such as LESS CSS, though I advise you compile to CSS for production use.

It's as simple as adding 2 lines of code to your HTML file.

<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>

As stated in one of the comments, this works for Mac (probably for Windows/Linux too):

I WANT TO CONNECT FROM A CONTAINER TO A SERVICE ON THE HOST

The host has a changing IP address (or none if you have no network access). We recommend that you connect to the special DNS name host.docker.internal which resolves to the internal IP address used by the host. This is for development purpose and will not work in a production environment outside of Docker Desktop for Mac.

You can also reach the gateway using gateway.docker.internal.

Quoted from https://docs.docker.com/docker-for-mac/networking/

This worked for me without using --net=host.

The uses of jQuery .queue() and .dequeue()

Queues in jQuery are used for animations. You can use them for any purpose you like. They are an array of functions stored on a per element basis, using jQuery.data(). They are First-In-First-Out (FIFO). You can add a function to the queue by calling .queue(), and you remove (by calling) the functions using .dequeue().

To understand the internal jQuery queue functions, reading the source and looking at examples helps me out tremendously. One of the best examples of a queue function I've seen is .delay():

$.fn.delay = function( time, type ) {
  time = jQuery.fx ? jQuery.fx.speeds[time] || time : time;
  type = type || "fx";

  return this.queue( type, function() {
    var elem = this;
    setTimeout(function() {
      jQuery.dequeue( elem, type );
    }, time );
  });
};

The default queue - fx

The default queue in jQuery is fx. The default queue has some special properties that are not shared with other queues.

1. Auto Start: When calling $(elem).queue(function(){}); the fx queue will automatically dequeue the next function and run it if the queue hasn't started.
2. 'inprogress' sentinel: Whenever you dequeue() a function from the fx queue, it will unshift() (push into the first location of the array) the string "inprogress" - which flags that the queue is currently being run.
3. It's the default! The fx queue is used by .animate() and all functions that call it by default.

NOTE: If you are using a custom queue, you must manually .dequeue() the functions, they will not auto start!

Retrieving/Setting the queue

You can retrieve a reference to a jQuery queue by calling .queue() without a function argument. You can use the method if you want to see how many items are in the queue. You can use push, pop, unshift, shift to manipulate the queue in place. You can replace the entire queue by passing an array to the .queue() function.

Quick Examples:

// lets assume $elem is a jQuery object that points to some element we are animating.
var queue = $elem.queue();
// remove the last function from the animation queue.
var lastFunc = queue.pop(); 
// insert it at the beginning:    
queue.unshift(lastFunc);
// replace queue with the first three items in the queue
$elem.queue(queue.slice(0,3)); 

An animation (fx) queue example:

Run example on jsFiddle

$(function() {
    // lets do something with google maps:
    var $map = $("#map_canvas");
    var myLatlng = new google.maps.LatLng(-34.397, 150.644);
    var myOptions = {zoom: 8, center: myLatlng, mapTypeId: google.maps.MapTypeId.ROADMAP};
    var geocoder = new google.maps.Geocoder();
    var map = new google.maps.Map($map[0], myOptions);
    var resized = function() {
        // simple animation callback - let maps know we resized
        google.maps.event.trigger(map, 'resize');
    };

    // wait 2 seconds
    $map.delay(2000);
    // resize the div:
    $map.animate({
        width: 250,
        height: 250,
        marginLeft: 250,
        marginTop:250
    }, resized);
    // geocode something
    $map.queue(function(next) {
        // find stackoverflow's whois address:
      geocoder.geocode({'address': '55 Broadway New York NY 10006'},handleResponse);

      function handleResponse(results, status) {
          if (status == google.maps.GeocoderStatus.OK) {
              var location = results[0].geometry.location;
              map.setZoom(13);
              map.setCenter(location);
              new google.maps.Marker({ map: map, position: location });
          }
          // geocoder result returned, continue with animations:
          next();
      }
    });
    // after we find stack overflow, wait 3 more seconds
    $map.delay(3000);
    // and resize the map again
    $map.animate({
        width: 500,
        height: 500,
        marginLeft:0,
        marginTop: 0
    }, resized);
});

Another custom queue example

Run example on jsFiddle

var theQueue = $({}); // jQuery on an empty object - a perfect queue holder

$.each([1,2,3],function(i, num) {
  // lets add some really simple functions to a queue:
  theQueue.queue('alerts', function(next) { 
    // show something, and if they hit "yes", run the next function.
    if (confirm('index:'+i+' = '+num+'\nRun the next function?')) {
      next();
    }
  }); 
});

// create a button to run the queue:
$("<button>", {
  text: 'Run Queue', 
  click: function() { 
    theQueue.dequeue('alerts'); 
  }
}).appendTo('body');

// create a button to show the length:
$("<button>", {
  text: 'Show Length', 
  click: function() { 
    alert(theQueue.queue('alerts').length); 
  }
}).appendTo('body');

Queueing Ajax Calls:

I developed an $.ajaxQueue() plugin that uses the $.Deferred, .queue(), and $.ajax() to also pass back a promise that is resolved when the request completes. Another version of $.ajaxQueue that still works in 1.4 is posted on my answer to Sequencing Ajax Requests

/*
* jQuery.ajaxQueue - A queue for ajax requests
* 
* (c) 2011 Corey Frang
* Dual licensed under the MIT and GPL licenses.
*
* Requires jQuery 1.5+
*/ 
(function($) {

// jQuery on an empty object, we are going to use this as our Queue
var ajaxQueue = $({});

$.ajaxQueue = function( ajaxOpts ) {
    var jqXHR,
        dfd = $.Deferred(),
        promise = dfd.promise();

    // queue our ajax request
    ajaxQueue.queue( doRequest );

    // add the abort method
    promise.abort = function( statusText ) {

        // proxy abort to the jqXHR if it is active
        if ( jqXHR ) {
            return jqXHR.abort( statusText );
        }

        // if there wasn't already a jqXHR we need to remove from queue
        var queue = ajaxQueue.queue(),
            index = $.inArray( doRequest, queue );

        if ( index > -1 ) {
            queue.splice( index, 1 );
        }

        // and then reject the deferred
        dfd.rejectWith( ajaxOpts.context || ajaxOpts,
            [ promise, statusText, "" ] );

        return promise;
    };

    // run the actual query
    function doRequest( next ) {
        jqXHR = $.ajax( ajaxOpts )
            .done( dfd.resolve )
            .fail( dfd.reject )
            .then( next, next );
    }

    return promise;
};

})(jQuery);

I have now added this as an article on learn.jquery.com, there are other great articles on that site about queues, go look.

I'm assuming that you want to be able to view data present in your container everytime you connect to it from outside. To do this, you will have to persist data on the postgres image.

If you dont have persistant data, you will have to repeat everything you did the first time.
Steps 3, 5, 6, 7, and 8 answer your question directly.

Here is the detailed overview of the entire process I followed on Windows 10 powershell (commands are the same in Linux and macOS as well):

Step 1: Start powershell in non-admin mode

Step 2: Download postgres docker image:
docker pull postgres:latest

Step 3: Start docker container in detached mode and persist data on postgres image by creating a volume and binding it to a destination
(Note: by default 5432 is the default port that is used; but state it explicitly to prevent connection errors from clients like pgadmin, dbeaver, etc.)
docker run --name postgres-test -e POSTGRES_PASSWORD=password -p 5432:5432 -v postgres-data:/var/lib/postgresql/data -d postgres:latest

Step 4: Check status of running containers
docker ps -a

Step 5: Go inside container_name in interactive mode
(Note: commands like ls, pwd, etc. can be executed here if you've checked linux containers during installation)
docker exec -it postgres-test psql -U postgres

Step 6: Create sample data. At this point, you can play with psql commands in the following manner:

# CREATE DATABASE test;
# \c test
# CREATE TABLE test_table(something int);
# INSERT INTO test_table VALUES (123);
# SELECT * FROM test_table;
# \q

Step 7: Open a database client application like pgadmin or dbeaver and enter the below in the connection fields:

Host: localhost
Database: test
User: postgres
Password: password

Step 8: Enter the query select * from test_table in the query editor and you should be able to see the output 123

if you use spring boot check in application.propertiese this property is commented or remove it if exist.

server.tomcat.additional-tld-skip-patterns=*.jar

with read

Here's an example that uses read to get the password and store it in the variable pass. Then, 7z uses the password to create an encrypted archive:

read -s -p "Enter password: " pass && 7z a archive.zip a_file -p"$pass"; unset pass

But be aware that the password can easily be sniffed.

Try removing the position from header and add overflow to container:

#container {
    position:relative;
    width:80%;
    height:auto;
    overflow:auto;
}
#header {
    width:80%;
    height:50px;
    padding:10px;
}

You can parse the pom file with JDOM (http://www.jdom.org/).

Same issue. What was actually happening was that the test running was trying to discover tests in a web site project I have loaded (there was some jasmine specs for angular inside the site).

This was causing the runner to hang trying to load some NodeJS Container

Updating containers from Microsoft.NodejsTools.TestAdapter.TestContainer

I removed the website from the solution (obviously, just the solution, not deleting the website!)

I also had some corrupt configuration data that I had to clear out under the TestStore folder in the .vs directory.

After completing these two steps things magically started working again

Since it's in bootstrap 3, the site will be using jQuery. So the solution could also be the following, instead of trying to play with complex CSS:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
    <link href="css/bootstrap.min.css" rel="stylesheet" />
    <style>
        .my-footer {
            border-radius : 0px;
            margin : 0px; /* pesky margin below .navbar */
            position : absolute;
            width : 100%;
        }
    </style>
</head>
<body>
    <div class="container-fluid">
        <div class="row">
            <!-- Content of any length -->
            asdfasdfasdfasdfs <br />
            asdfasdfasdfasdfs <br />
            asdfasdfasdfasdfs <br />
        </div>
    </div>

    <div class="navbar navbar-inverse my-footer">
        <div class="container-fluid">
            <div class="row">
                <p class="navbar-text">My footer content goes here...</p>
            </div>
        </div>
    </div>

    <script src="js/jquery-1.11.0.min.js"></script>
    <script src="js/bootstrap.min.js"></script>

    <script type="text/javascript">
        $(document).ready(function () {
            var $docH = $(document).height();
            // The document height will grow as the content on the page grows.
            $('.my-footer').css({
                /*
                The default height of .navbar is 50px with a 1px border,
                change this 52 if you change the height of your footer.
                */
                top: ($docH - 52) + 'px'
            });
        });
    </script>
</body>
</html>

A different take on it, hope it helps.

Kind regards.

Try

$(document).ready(

instead of

$('document').ready(

or you can use a shorthand form

$(function(){
});

EDIT: to convert to array

int[] asIntegers = arr.Select(s => int.Parse(s)).ToArray();

This should do the trick:

var asIntegers = arr.Select(s => int.Parse(s));

I put the JRE folder from the JDK installation directory to the Eclipse installation directory (the folder which contains the eclipse.exe file). It worked for me.

A DataFrame follows the dict-like convention of iterating over the “keys” of the objects.

my_dataframe.keys()

Create a list of keys/columns - object method to_list() and pythonic way

my_dataframe.keys().to_list()
list(my_dataframe.keys())

Basic iteration on a DataFrame returns column labels

[column for column in my_dataframe]

Do not convert a DataFrame into a list, just to get the column labels. Do not stop thinking while looking for convenient code samples.

xlarge = pd.DataFrame(np.arange(100000000).reshape(10000,10000))
list(xlarge) #compute time and memory consumption depend on dataframe size - O(N)
list(xlarge.keys()) #constant time operation - O(1)

No. It's per command, not per connection.

Edit, May 2013

As requested in comment:

• SQLCommand.CommandTimeout for command execution
• There is no matching SQLConnection property (the questions says not the SqlConnection.ConnectionTimeout property

Some more notes about commands and execution time outs in SQL Server (DBA.SE). And more SO stuff: What happens to an uncommitted transaction when the connection is closed?

Please also make sure to use await and async in you method. You can get this error if your object are not serialized properly.

urllib has been split up in Python 3.

The urllib.urlencode() function is now urllib.parse.urlencode(),

the urllib.urlopen() function is now urllib.request.urlopen().

This will get you the hours, minutes and second. hey presto.

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

Simply run the alter table query using 'KEY' instead of 'FOREIGN KEY' in the drop statement. I hope it will help to solve the issue, and will drop the foreign key constraint and you can change the table columns and drop the table.

ALTER TABLE slide_image_sub DROP  KEY  FK_slide_image_sub;

here in DROP KEY instead of DROP FOREIGN KEY,

hope it will help.

Thanks

For changing application name only (that will display along with app icon) in xcode 4 or later:

Click on your project file icon from Groups & Files panel, choose Target -> Build Settings -> Packaging -> Product Name. Click on the row, a pop-up will come, type your new app name here.

For changing Project name only (that will display along with project icon) in xcode 4 or later:

Click on your project file icon from Groups & Files panel, choose Project(above targets) from right pane, just see at the far right pane(it will be visible only if you have enabled "Hide or show utilities").Look for project name.Edit it to new name you want to give your project.

Delete your app from simulator/device, clean and run.Changes should reflect.

That's it

Just leave out the ''

The question was: "Is it possible to make a HTML5 slider with two input values, for example to select a price range? If so, how can it be done?"

Ten years ago the answer was probably 'No'. However, times have changed. In 2020 it is finally possible to create a fully accessible, native, non-jquery HTML5 slider with two thumbs for price ranges. If found this posted after I already created this solution and I thought that it would be nice to share my implementation here.

This implementation has been tested on mobile Chrome and Firefox (Android) and Chrome and Firefox (Linux). I am not sure about other platforms, but it should be quite good. I would love to get your feedback and improve this solution.

This solution allows multiple instances on one page and it consists of just two inputs (each) with descriptive labels for screen readers. You can set the thumb size in the amount of grid labels. Also, you can use touch, keyboard and mouse to interact with the slider. The value is updated during adjustment, due to the 'on input' event listener.

My first approach was to overlay the sliders and clip them. However, that resulted in complex code with a lot of browser dependencies. Then I recreated the solution with two sliders that were 'inline'. This is the solution you will find below.

var thumbsize = 14;

function draw(slider,splitvalue) {

    /* set function vars */
    var min = slider.querySelector('.min');
    var max = slider.querySelector('.max');
    var lower = slider.querySelector('.lower');
    var upper = slider.querySelector('.upper');
    var legend = slider.querySelector('.legend');
    var thumbsize = parseInt(slider.getAttribute('data-thumbsize'));
    var rangewidth = parseInt(slider.getAttribute('data-rangewidth'));
    var rangemin = parseInt(slider.getAttribute('data-rangemin'));
    var rangemax = parseInt(slider.getAttribute('data-rangemax'));

    /* set min and max attributes */
    min.setAttribute('max',splitvalue);
    max.setAttribute('min',splitvalue);

    /* set css */
    min.style.width = parseInt(thumbsize + ((splitvalue - rangemin)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
    max.style.width = parseInt(thumbsize + ((rangemax - splitvalue)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
    min.style.left = '0px';
    max.style.left = parseInt(min.style.width)+'px';
    min.style.top = lower.offsetHeight+'px';
    max.style.top = lower.offsetHeight+'px';
    legend.style.marginTop = min.offsetHeight+'px';
    slider.style.height = (lower.offsetHeight + min.offsetHeight + legend.offsetHeight)+'px';
    
    /* correct for 1 off at the end */
    if(max.value>(rangemax - 1)) max.setAttribute('data-value',rangemax);

    /* write value and labels */
    max.value = max.getAttribute('data-value'); 
    min.value = min.getAttribute('data-value');
    lower.innerHTML = min.getAttribute('data-value');
    upper.innerHTML = max.getAttribute('data-value');

}

function init(slider) {
    /* set function vars */
    var min = slider.querySelector('.min');
    var max = slider.querySelector('.max');
    var rangemin = parseInt(min.getAttribute('min'));
    var rangemax = parseInt(max.getAttribute('max'));
    var avgvalue = (rangemin + rangemax)/2;
    var legendnum = slider.getAttribute('data-legendnum');

    /* set data-values */
    min.setAttribute('data-value',rangemin);
    max.setAttribute('data-value',rangemax);
    
    /* set data vars */
    slider.setAttribute('data-rangemin',rangemin); 
    slider.setAttribute('data-rangemax',rangemax); 
    slider.setAttribute('data-thumbsize',thumbsize); 
    slider.setAttribute('data-rangewidth',slider.offsetWidth);

    /* write labels */
    var lower = document.createElement('span');
    var upper = document.createElement('span');
    lower.classList.add('lower','value');
    upper.classList.add('upper','value');
    lower.appendChild(document.createTextNode(rangemin));
    upper.appendChild(document.createTextNode(rangemax));
    slider.insertBefore(lower,min.previousElementSibling);
    slider.insertBefore(upper,min.previousElementSibling);
    
    /* write legend */
    var legend = document.createElement('div');
    legend.classList.add('legend');
    var legendvalues = [];
    for (var i = 0; i < legendnum; i++) {
        legendvalues[i] = document.createElement('div');
        var val = Math.round(rangemin+(i/(legendnum-1))*(rangemax - rangemin));
        legendvalues[i].appendChild(document.createTextNode(val));
        legend.appendChild(legendvalues[i]);

    } 
    slider.appendChild(legend);

    /* draw */
    draw(slider,avgvalue);

    /* events */
    min.addEventListener("input", function() {update(min);});
    max.addEventListener("input", function() {update(max);});
}

function update(el){
    /* set function vars */
    var slider = el.parentElement;
    var min = slider.querySelector('#min');
    var max = slider.querySelector('#max');
    var minvalue = Math.floor(min.value);
    var maxvalue = Math.floor(max.value);
    
    /* set inactive values before draw */
    min.setAttribute('data-value',minvalue);
    max.setAttribute('data-value',maxvalue);

    var avgvalue = (minvalue + maxvalue)/2;

    /* draw */
    draw(slider,avgvalue);
}

var sliders = document.querySelectorAll('.min-max-slider');
sliders.forEach( function(slider) {
    init(slider);
});

d = DateTime.now.utc

Oops!

That seems to work in Rails, but not vanilla Ruby (and of course that is what the question is asking)

d = Time.now.utc

Does work however.

Is there any reason you need to use DateTime and not Time? Time should include everything you need:

irb(main):016:0> Time.now
=> Thu Apr 16 12:40:44 +0100 2009

I tried the solutions given here while working on an application that used Bluetooth Low Energy(BLE). I tried,

1. Clean Build
2. Disabled Instant Run
3. Invalidate Caches / Restart

all of these failed.

What I did was debug the points where I thought I was getting the warning, I still got the warning but the application was working fine. You can disregard the warning.

By checking out to one of the commits in the history you are moving your git into so called 'detached state', which looks like is not what you want. Use this single command to create a new branch on one of the commits from the history:

git checkout -b <new_branch_name> <SHA1>

When you start SSMS, it allows you to choose a Server Type and Server Name. In the server type dropdown, choose "Integration Services" and connect to the server.

Then you'll be able to see what packages are in the db.

The size of PHP ints is platform dependent:

The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value (that's 32 bits signed). PHP does not support unsigned integers. Integer size can be determined using the constant PHP_INT_SIZE, and maximum value using the constant PHP_INT_MAX since PHP 4.4.0 and PHP 5.0.5.

PHP 6 adds "longs" (64 bit ints).

This one worked for me:

In Activity:

User user;
public User getUser(){ return this.user;}

In Fragment's onCreateView method:

User user = ((MainActivity)getActivity()).getUser(); 

Replace the MainActivity with your Activity Name.

Change the checkboxes so that the name includes the index inside the brackets:

<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>"> 

The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.

Spinner don't support Hint, i recommend you to make a custom spinner adapter.

check this link : https://stackoverflow.com/a/13878692/1725748

Use the not (^) symbol:

.*[^a]$

If you put the ^ symbol at the beginning of brackets, it means "everything except the things in the brackets." $ is simply an anchor to the end.

For multiple characters, just put them all in their own character set:

.*[^a][^b]$

This worked for me:

find /A -type d -exec chmod 0755 {} \;
find /A -type f -exec chmod 0644 {} \;

(INNER) JOIN: Returns records that have matching values in both tables.

LEFT (OUTER) JOIN: Return all records from the left table, and the matched records from the right table.

RIGHT (OUTER) JOIN: Return all records from the right table, and the matched records from the left table.

FULL (OUTER) JOIN: Return all records when there is a match in either left or right table

For example, lets suppose we have two table with following records:

Table A

id   firstname   lastname
___________________________
1     Ram         Thapa
2     sam         Koirala
3     abc         xyz
6    sruthy       abc

Table B

id2   place
_____________
1      Nepal
2      USA
3      Lumbini
5      Kathmandu

Inner Join

Note: It give the intersection of two table.

Syntax

SELECT column_name FROM table1 INNER JOIN table2 ON table1.column_name = table2.column_name;

Apply it in your sample table:

SELECT TableA.firstName,TableA.lastName,TableB.Place FROM TableA INNER JOIN TableB ON TableA.id = TableB.id2;

Result will be:

firstName       lastName       Place
_____________________________________
  Ram         Thapa             Nepal
  sam         Koirala            USA
  abc         xyz              Lumbini

Left Join

Note : will give all selected rows in TableA, plus any common selected rows in TableB.

SELECT column_name(s) FROM table1 LEFT JOIN table2 ON table1.column_name = table2.column_name;

Apply it in your sample table

SELECT TableA.firstName,TableA.lastName,TableB.Place FROM TableA LEFT JOIN TableB ON TableA.id = TableB.id2;

Result will be:

firstName   lastName    Place
______________________________
 Ram         Thapa      Nepal
 sam         Koirala    USA
 abc         xyz        Lumbini
sruthy       abc        Null

Right Join

Note:will give all selected rows in TableB, plus any common selected rows in TableA.

Syntax:

SELECT column_name(s) FROM table1 RIGHT JOIN table2 ON table1.column_name = table2.column_name;

Apply it in your samole table:

SELECT TableA.firstName,TableA.lastName,TableB.Place FROM TableA RIGHT JOIN TableB ON TableA.id = TableB.id2;

Result will bw:

firstName   lastName     Place
______________________________
Ram         Thapa         Nepal
sam         Koirala       USA
abc         xyz           Lumbini
Null        Null          Kathmandu

Full Join

Note : It is same as union operation, it will return all selected values from both tables.

Syntax:

SELECT column_name(s) FROM table1 FULL OUTER JOIN table2 ON table1.column_name = table2.column_name;

Apply it in your samp[le table:

SELECT TableA.firstName,TableA.lastName,TableB.Place FROM TableA FULL JOIN TableB ON TableA.id = TableB.id2;

Result will be:

firstName   lastName    Place
______________________________
 Ram         Thapa      Nepal
 sam         Koirala    USA
 abc         xyz        Lumbini
sruthy       abc        Null
 Null         Null      Kathmandu

Some facts

For INNER joins the order doesn't matter

For (LEFT, RIGHT or FULL) OUTER joins,the order matter

Some of the data processing requirements doesn't need sort at all. Syncsort had made the sorting in Hadoop pluggable. Here is a nice blog from them on sorting. The process of moving the data from the mappers to the reducers is called shuffling, check this article for more information on the same.

IMDbPY is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters and companies.

http://imdbpy.sourceforge.net/

If you want to be able to perform a lookup on each type to get its frequency then you will need to transform the enumeration into a dictionary.

var types = new[] {typeof(string), typeof(string), typeof(int)};
var x = types
        .GroupBy(type => type)
        .ToDictionary(g => g.Key, g => g.Count());
foreach (var kvp in x) {
    Console.WriteLine("Type {0}, Count {1}", kvp.Key, kvp.Value);
}
Console.WriteLine("string has a count of {0}", x[typeof(string)]);

About all you can do is search DNS and ensure the domain that is in the email address has an MX record, other than that there is no reliable way of dealing with this.

Some servers may work with the rcpt-to method where you talk to the SMTP server, but it depends entirely on the configuration of the server. Another issue may be an overloaded server may return a 550 code saying user is unknown, but this is a temporary error, there is a permanent error (451 i think?) that can be returned. This depends entirely on the configuration of the server.

I personally would check for the DNS MX record, then send an email verification if the MX record exists.

I just got into the same problem and it looks like EntityFramework although installed from NuGet Package Manager was not correctly installed in the project.

I managed to fix it by running the following command on Package Manager Console:

PM> Install-Package EntityFramework

just use this class : TouchImageView

Right here: http://jt400.sourceforge.net/

This is what I use for that exact purpose.

EDIT: Usage Examples (minus exceptions):

// Driver initialization
AS400JDBCDriver driver = new com.ibm.as400.access.AS400JDBCDriver();
DriverManager.registerDriver(driver);

// JDBC Connection URL
String url = "jdbc:as400://10.10.10.10" + ";promt=false" // disable GUI prompting by jt400 library

// Get a Connection object (this is used to create statements, etc)
Connection conn = DriverManager.getConnection(url, UserString, PassString);

Hope that helps!

V.push_back(8);
V.push_back(5);
V.push_back(7);

copy(V.begin(), V.end(), ostream_iterator<int>(cout, " "));
    // The output is "1 4 2 8 5 7"

vector<int>::iterator new_end = 
    remove_if(V.begin(), V.end(), 
              compose1(bind2nd(equal_to<int>(), 0),
                       bind2nd(modulus<int>(), 2)));
V.erase(new_end, V.end()); [1]

copy(V.begin(), V.end(), ostream_iterator<int>(cout, " "));
    // The output is "1 5 7".

A broader answer to this question might consider the Lego brick approach often used in Occam, and offered to the Java community via JCSP. There is a very good presentation by Peter Welch on this idea.

This plug-and-play approach translates directly to Go, because Go uses the same Communicating Sequential Process fundamentals as does Occam.

So, when it comes to designing repetitive tasks, you can build your system as a dataflow network of simple components (as goroutines) that exchange events (i.e. messages or signals) via channels.

This approach is compositional: each group of small components can itself behave as a larger component, ad infinitum. This can be very powerful because complex concurrent systems are made from easy to understand bricks.

Footnote: in Welch's presentation, he uses the Occam syntax for channels, which is ! and ? and these directly correspond to ch<- and <-ch in Go.

The phrases minimum time and maximum time are a bit misleading here. When we talk about big O notations, it's not the actual time we are interested in, it is how the time increases when our input size gets bigger. And it's usually the average or worst case time we are talking about, not best case, which usually is not meaningful in solving our problems.

Using the array search in the accepted answer to the other question as an example. The time it takes to find a particular number in list of size n is n/2 * some_constant in average. If you treat it as a function f(n) = n/2*some_constant, it increases no faster than g(n) = n, in the sense as given by Charlie. Also, it increases no slower than g(n) either. Hence, g(n) is actually both an upper bound and a lower bound of f(n) in Big-O notation, so the complexity of linear search is exactly n, meaning that it is Theta(n).

In this regard, the explanation in the accepted answer to the other question is not entirely correct, which claims that O(n) is upper bound because the algorithm can run in constant time for some inputs (this is the best case I mentioned above, which is not really what we want to know about the running time).

Here's my adaptation of Ates Goral's answer using C++11. I've added the lambda in here, but the principle is that you could pass it in and thereby control what characters your string contains:

std::string random_string( size_t length )
{
    auto randchar = []() -> char
    {
        const char charset[] =
        "0123456789"
        "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
        "abcdefghijklmnopqrstuvwxyz";
        const size_t max_index = (sizeof(charset) - 1);
        return charset[ rand() % max_index ];
    };
    std::string str(length,0);
    std::generate_n( str.begin(), length, randchar );
    return str;
}

Here is an example of passing in a lambda to the random string function: http://ideone.com/Ya8EKf

Why would you use C++11?

1. Because you can produce strings that follow a certain probability distribution (or distribution combination) for the character set you're interested in.
2. Because it has built-in support for non-deterministic random numbers
3. Because it supports unicode, so you could change this to an internationalized version.

For example:

#include <iostream>
#include <vector>
#include <random>
#include <functional> //for std::function
#include <algorithm>  //for std::generate_n

typedef std::vector<char> char_array;

char_array charset()
{
    //Change this to suit
    return char_array( 
    {'0','1','2','3','4',
    '5','6','7','8','9',
    'A','B','C','D','E','F',
    'G','H','I','J','K',
    'L','M','N','O','P',
    'Q','R','S','T','U',
    'V','W','X','Y','Z',
    'a','b','c','d','e','f',
    'g','h','i','j','k',
    'l','m','n','o','p',
    'q','r','s','t','u',
    'v','w','x','y','z'
    });
};    

// given a function that generates a random character,
// return a string of the requested length
std::string random_string( size_t length, std::function<char(void)> rand_char )
{
    std::string str(length,0);
    std::generate_n( str.begin(), length, rand_char );
    return str;
}

int main()
{
    //0) create the character set.
    //   yes, you can use an array here, 
    //   but a function is cleaner and more flexible
    const auto ch_set = charset();

    //1) create a non-deterministic random number generator      
    std::default_random_engine rng(std::random_device{}());

    //2) create a random number "shaper" that will give
    //   us uniformly distributed indices into the character set
    std::uniform_int_distribution<> dist(0, ch_set.size()-1);

    //3) create a function that ties them together, to get:
    //   a non-deterministic uniform distribution from the 
    //   character set of your choice.
    auto randchar = [ ch_set,&dist,&rng ](){return ch_set[ dist(rng) ];};

    //4) set the length of the string you want and profit!        
    auto length = 5;
    std::cout<<random_string(length,randchar)<<std::endl;
    return 0;
}

As of July 25, 2011, the answer is no.

I have looked through their Javascript and it seems they don't want anyone directly accessing their api for +1 at the moment.

The Javascript that does all of the work for the +1 button is here:

https://apis.google.com/js/plusone.js

If you run it through a Javascript cleanup program you can tell that they have obfuscated their code with various functions that only start with letters and constantly refer back to themselves and do cryptic things.

I figure in the next couple of weeks or moths they will release a link based sharing api due to the fact that we will need this for sharing from flash and other web based formats that don't rely on pure html and js.

In your sample code, it would just be $key.

If you want to know, for example, if this is the first, second, or i^th iteration of the loop, this is your only option:

$i = -1;
foreach($arr as $val) {
  $i++;
  //$i is now the index.  if $i == 0, then this is the first element.
  ...
}

Of course, this doesn't mean that $val == $arr[$i] because the array could be an associative array.

Interned Strings avoid duplicate Strings. Interning saves RAM at the expense of more CPU time to detect and replace duplicate Strings. There is only one copy of each String that has been interned, no matter how many references point to it. Since Strings are immutable, if two different methods incidentally use the same String, they can share a copy of the same String. The process of converting duplicated Strings to shared ones is called interning.String.intern() gives you the address of the canonical master String. You can compare interned Strings with simple == (which compares pointers) instead of equals which compares the characters of the String one by one. Because Strings are immutable, the intern process is free to further save space, for example, by not creating a separate String literal for "pot" when it exists as a substring of some other literal such as "hippopotamus".

I tried the steps that @KannarKK suggested on ES 2.0.2, however, I could not bring the cluster up and running. Evidently, I figured out something, as I had set tcp port number on Master, on the Slave configuration discovery.zen.ping.unicast.hosts needs Master's port number along with IP address ( tcp port number ) for discovery. So when I try following configuration it works for me.

Node 1

cluster.name: mycluster
node.name: "node1"
node.master: true
node.data: true
http.port : 9200
tcp.port : 9300
discovery.zen.ping.multicast.enabled: false
# I think unicast.host on master is redundant.
discovery.zen.ping.unicast.hosts: ["node1.example.com"]

Node 2

cluster.name: mycluster
node.name: "node2"
node.master: false
node.data: true
http.port : 9201
tcp.port : 9301
discovery.zen.ping.multicast.enabled: false
# The port number of Node 1
discovery.zen.ping.unicast.hosts: ["node1.example.com:9300"]

My recommendation is to never lower your openssl lib version for the sake of getting your build to work. Better to download the source code of the required lib and build it against the openssl version you have on your localhost.

I came across this posting while going through the same issue but was not comfortable lowering the openssl version come what may. Finally took the source code and build the app and it worked. I dont know why devs have their old versions of openssl on their boxes and which they build the dist packages and publish against those old version.

The pygame documentation for mouse events is here. You can either use the pygame.mouse.get_pressed method in collaboration with the pygame.mouse.get_pos (if needed). But please use the mouse click event via a main event loop. The reason why the event loop is better is due to "short clicks". You may not notice these on normal machines, but computers that use tap-clicks on trackpads have excessively small click periods. Using the mouse events will prevent this.

EDIT: To perform pixel perfect collisions use pygame.sprite.collide_rect() found on their docs for sprites.

This works fine for me.

f = open(file_path, 'r+', encoding="utf-8")

You can add a third parameter encoding to ensure the encoding type is 'utf-8'

Note: this method works fine in Python3, I did not try it in Python2.7.

I could use the following code. Thanks everyone.

int intID = 5;
DataTable Dt = MyFuctions.GetData();
Dt.PrimaryKey = new DataColumn[] { Dt.Columns["ID"] };
DataRow Drw = Dt.Rows.Find(intID);
if (Drw != null) Dt.Rows.Remove(Drw);

One way to achieve this is using a position:fixed container for the background image and place it outside of the .jumbotron. Make the bg container the same height as the .jumbotron and center the background image:

background: url('/assets/example/...jpg') no-repeat center center;

CSS

.bg {
  background: url('/assets/example/bg_blueplane.jpg') no-repeat center center;
  position: fixed;
  width: 100%;
  height: 350px; /*same height as jumbotron */
  top:0;
  left:0;
  z-index: -1;
}

.jumbotron {
  margin-bottom: 0px;
  height: 350px;
  color: white;
  text-shadow: black 0.3em 0.3em 0.3em;
  background:transparent;
}

Then use jQuery to decrease the height of the .jumbtron as the window scrolls. Since the background image is centered in the DIV it will adjust accordingly -- creating a parallax affect.

JavaScript

var jumboHeight = $('.jumbotron').outerHeight();
function parallax(){
    var scrolled = $(window).scrollTop();
    $('.bg').css('height', (jumboHeight-scrolled) + 'px');
}

$(window).scroll(function(e){
    parallax();
});

This should do it (bold as well);

@Baba's answer is great. But you don't need to use explode because fputcsv takes an array as a parameter

For instance, if you have a three columns, four lines document, here's a more straight version:

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');

$user_CSV[0] = array('first_name', 'last_name', 'age');

// very simple to increment with i++ if looping through a database result 
$user_CSV[1] = array('Quentin', 'Del Viento', 34);
$user_CSV[2] = array('Antoine', 'Del Torro', 55);
$user_CSV[3] = array('Arthur', 'Vincente', 15);

$fp = fopen('php://output', 'wb');
foreach ($user_CSV as $line) {
    // though CSV stands for "comma separated value"
    // in many countries (including France) separator is ";"
    fputcsv($fp, $line, ',');
}
fclose($fp);

As an alternative option you could install OpenSSH http://www.mls-software.com/opensshd.html and then simply ssh user@host -pw password -m command_run

Edit: After a response from user2687375 when installing, select client only. Once this is done you should be able to initiate SSH from command.

Then you can create an ssh batch script such as

ECHO OFF
CLS
:MENU
ECHO.
ECHO ........................
ECHO SSH servers
ECHO ........................
ECHO.
ECHO 1 - Web Server 1
ECHO 2 - Web Server 2
ECHO E - EXIT
ECHO.

SET /P M=Type 1 - 2 then press ENTER:
IF %M%==1 GOTO WEB1
IF %M%==2 GOTO WEB2
IF %M%==E GOTO EOF

REM ------------------------------
REM SSH Server details
REM ------------------------------

:WEB1
CLS
call ssh [email protected]
cmd /k

:WEB2

call ssh [email protected]
cmd /k

If you want to modify the line width flexibly you can use "scale_size_manual," this is the same procedure for picking the color, fill, alpha, etc.

                 C = 30 - x**1.5,
                 X = x)


df = gather(df,A,B,C,key="Model",value="Y")


ggplot( df, aes (x=X, y=Y, size=Model, colour=Model ))+
  geom_line()+
  scale_size_manual( values = c(4,2,1) ) +
  scale_color_manual( values = c("orange","red","navy") )

I had the same problem and spent about 6 hours to solve it. I didn't find that answer for exactly my situation so maybe it could be useful for somebody.

When I created project, I pointed GroupId in pom.xml as "myproject.myapp" but I didn't create first "prime" package with that name in the project, where would be other packages inside of this main package (like /src/main/app etc). When I created prime package "myproject.myapp" and moved other packages inside of it, the problem was solved.

You can use java 8 now:

Collections.addAll(list, arr);
Collections.shuffle(list);
cardsList.toArray(arr);

Very simple way to do this---

In your Activity--

 TextView tv = (TextView) findViewById(R.id.site);
 tv.setText(Html.fromHtml("<a href=http://www.stackoverflow.com> STACK OVERFLOW "));
 tv.setMovementMethod(LinkMovementMethod.getInstance());

Then you will get just the Tag, not the whole link..

Hope it will help you...

unicode_escape doesn't work in general

It turns out that the string_escape or unicode_escape solution does not work in general -- particularly, it doesn't work in the presence of actual Unicode.

If you can be sure that every non-ASCII character will be escaped (and remember, anything beyond the first 128 characters is non-ASCII), unicode_escape will do the right thing for you. But if there are any literal non-ASCII characters already in your string, things will go wrong.

unicode_escape is fundamentally designed to convert bytes into Unicode text. But in many places -- for example, Python source code -- the source data is already Unicode text.

The only way this can work correctly is if you encode the text into bytes first. UTF-8 is the sensible encoding for all text, so that should work, right?

The following examples are in Python 3, so that the string literals are cleaner, but the same problem exists with slightly different manifestations on both Python 2 and 3.

>>> s = 'naïve \\t test'
>>> print(s.encode('utf-8').decode('unicode_escape'))
naïve   test

Well, that's wrong.

The new recommended way to use codecs that decode text into text is to call codecs.decode directly. Does that help?

>>> import codecs
>>> print(codecs.decode(s, 'unicode_escape'))
naïve   test

Not at all. (Also, the above is a UnicodeError on Python 2.)

The unicode_escape codec, despite its name, turns out to assume that all non-ASCII bytes are in the Latin-1 (ISO-8859-1) encoding. So you would have to do it like this:

>>> print(s.encode('latin-1').decode('unicode_escape'))
naïve    test

But that's terrible. This limits you to the 256 Latin-1 characters, as if Unicode had never been invented at all!

>>> print('Erno \\t Rubik'.encode('latin-1').decode('unicode_escape'))
UnicodeEncodeError: 'latin-1' codec can't encode character '\u0151'
in position 3: ordinal not in range(256)

Adding a regular expression to solve the problem

(Surprisingly, we do not now have two problems.)

What we need to do is only apply the unicode_escape decoder to things that we are certain to be ASCII text. In particular, we can make sure only to apply it to valid Python escape sequences, which are guaranteed to be ASCII text.

The plan is, we'll find escape sequences using a regular expression, and use a function as the argument to re.sub to replace them with their unescaped value.

import re
import codecs

ESCAPE_SEQUENCE_RE = re.compile(r'''
    ( \\U........      # 8-digit hex escapes
    | \\u....          # 4-digit hex escapes
    | \\x..            # 2-digit hex escapes
    | \\[0-7]{1,3}     # Octal escapes
    | \\N\{[^}]+\}     # Unicode characters by name
    | \\[\\'"abfnrtv]  # Single-character escapes
    )''', re.UNICODE | re.VERBOSE)

def decode_escapes(s):
    def decode_match(match):
        return codecs.decode(match.group(0), 'unicode-escape')

    return ESCAPE_SEQUENCE_RE.sub(decode_match, s)

And with that:

>>> print(decode_escapes('Erno \\t Rubik'))
Erno     Rubik

The main problem for causing your table unable to migrate, is that you have running query on your "AppServiceProvider.php" try to check your serviceprovider and disable code for the meantime, and run php artisan migrate

The following lines of code are working properly. You can assign the classes like text-center, left or right, The text will align accordingly.

<p class="text-center">Day 1</p> 
<p class="text-left">Day 2</p> 
<p class="text-right">Day 3</p>

Here there isn't any need to create any external class. These are the Bootstrap classes and have their own property.

There are multiple number groups and some particular numbers that will never be allocated:

• Numbers with all zeros in any digit group (000-xx-####, ###-00-####, ###-xx-0000).
• Numbers with an area group (first three digits) of 666 or any of 900-999.
• Numbers that have been misused in any way, such as the well known 078-05-1120.

Consider using one of these (the obviously invalid 000-00-0000 would be a good one IMO).

I had to face this problem too and had a work around which i checked on HTC one, galaxy s1, s2, s3, note and HTC sensation.

put a global layout listener on the root view of your layout

mRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener(){
            public void onGlobalLayout() {
                checkHeightDifference();
            }
    });

and in there i checked the height difference and if the height difference of the screen is bigger then a third on the screen height then we can assume the keyboard is open. took it from this answer.

private void checkHeightDifference(){
    // get screen frame rectangle 
    Rect r = new Rect();
    mRootView.getWindowVisibleDisplayFrame(r);
    // get screen height
    int screenHeight = mRootView.getRootView().getHeight();
    // calculate the height difference
    int heightDifference = screenHeight - (r.bottom - r.top);

    // if height difference is different then the last height difference and
    // is bigger then a third of the screen we can assume the keyboard is open
    if (heightDifference > screenHeight/3 && heightDifference != mLastHeightDifferece) {
        // keyboard visiblevisible
        // get root view layout params
        FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) mRootView.getLayoutParams();
        // set the root view height to screen height minus the height difference
        lp.height = screenHeight - heightDifference;
        // call request layout so the changes will take affect
        .requestLayout();
        // save the height difference so we will run this code only when a change occurs.
        mLastHeightDifferece = heightDifference;
    } else if (heightDifference != mLastHeightDifferece) {
        // keyboard hidden
        PFLog.d("[ChatroomActivity] checkHeightDifference keyboard hidden");
        // get root view layout params and reset all the changes we have made when the keyboard opened.
        FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) mRootView.getLayoutParams();
        lp.height = screenHeight;
        // call request layout so the changes will take affect
        mRootView.requestLayout();
        // save the height difference so we will run this code only when a change occurs.
        mLastHeightDifferece = heightDifference;
    }
}

this is probably not bullet proof and maybe on some devices it will not work but it worked for me and hope it will help you too.

Yo can simply google for "exit sub in c#".

Also why would you check every text box if it is empty. You can place requiredfieldvalidator for these text boxes if this is an asp.net app and check if(Page.IsValid)

Or another solution is to get not of these conditions:

private void button1_Click(object sender, EventArgs e)
{
    if (!(textBox1.Text == "" || textBox2.Text == "" || textBox3.Text == ""))
    {
        //do events
    }
}

And better use String.IsNullOrEmpty:

private void button1_Click(object sender, EventArgs e)
{
    if (!(String.IsNullOrEmpty(textBox1.Text)
    || String.IsNullOrEmpty(textBox2.Text)
    || String.IsNullOrEmpty(textBox3.Text)))
    {
        //do events
    }
}

dictionary['key'] = dictionary.get('key', []) + list_to_append

Use BigDecimal.valueOf(double d) instead of new BigDecimal(double d). The last one has precision errors by float and double.

Well, this is really not very complicated. I have strong suspicion you didn't even try. What you do is that you pick the first value, save it in the variable, and then, within a for loop, compare all subsequent values with the first one.
I intentionally didn't share any code. Find how for is used and how variables are compared.

Here is my solution. It uses AnimatorSet. AnimationSet library was too buggy to get working. This provides seamless and infinite transitions between fade in and out.

public static void setAlphaAnimation(View v) {
    ObjectAnimator fadeOut = ObjectAnimator.ofFloat(v, "alpha",  1f, .3f);
    fadeOut.setDuration(2000);
    ObjectAnimator fadeIn = ObjectAnimator.ofFloat(v, "alpha", .3f, 1f);
    fadeIn.setDuration(2000);

    final AnimatorSet mAnimationSet = new AnimatorSet();

    mAnimationSet.play(fadeIn).after(fadeOut);

    mAnimationSet.addListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationEnd(Animator animation) {
            super.onAnimationEnd(animation);
            mAnimationSet.start();
        }
    });
    mAnimationSet.start();
}

SELECT name
FROM sys.objects
WHERE type = 'P'
AND (DATEDIFF(D,modify_date, GETDATE()) < 7
     OR DATEDIFF(D,create_date, GETDATE()) < 7)

Write "var" before variables, when you define them. IE8 dies when there is no "var".

It is a general vision. Details are depended on real language realisation

lock - thread synchronization tool. When thread get a lock it becomes a single thread which is able to execute a block of code. All others thread are blocked. Only thread which owns by lock can unlock it

mutex - mutual exclusion lock. It is a kind of lock. On some languages it is inter-process mechanism, on some languages it is a synonym of lock. For example Java uses lock in synchronised and java.util.concurrent.locks.Lock

semaphore - allows a number of threads to access a shared resource. You can find that mutex also can be implemented by semaphore. It is a standalone object which manage an access to shared resource. You can find that any thread can signal and unblock. Also it is used for signalling

[iOS lock, mutex, semaphore]

I do not unit test private methods. A private method is an implementation detail that should be hidden to the users of the class. Testing private methods breaks encapsulation.

If I find that the private method is huge or complex or important enough to require its own tests, I just put it in another class and make it public there (Method Object). Then I can easily test the previously-private-but-now-public method that now lives on its own class.

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

CAVEAT: Please remove anonymous users !!!

I had a similar problem that I am facing where I need to store live candlesticks from an event source limited to x items. I could have them stored in an object where the timestamp of each candle would act as the key and the candle itself would act as the value. Another possibility was that I could store it in an array where each item was the candle itself. One problem about live candles is that they keep sending updates on the same timestamp where the latest update holds the most recent data therefore you either update an existing item or add a new one. So here is a nice benchmark that attempts to combine all 3 possibilities. Arrays in the solution below are atleast 4x faster on average. Feel free to play

"use strict";

const EventEmitter = require("events");
let candleEmitter = new EventEmitter();

//Change this to set how fast the setInterval should run
const frequency = 1;

setInterval(() => {
    // Take the current timestamp and round it down to the nearest second
    let time = Math.floor(Date.now() / 1000) * 1000;
    let open = Math.random();
    let high = Math.random();
    let low = Math.random();
    let close = Math.random();
    let baseVolume = Math.random();
    let quoteVolume = Math.random();

    //Clear the console everytime before printing fresh values
    console.clear()

    candleEmitter.emit("candle", {
        symbol: "ABC:DEF",
        time: time,
        open: open,
        high: high,
        low: low,
        close: close,
        baseVolume: baseVolume,
        quoteVolume: quoteVolume
    });



}, frequency)

// Test 1 would involve storing the candle in an object
candleEmitter.on('candle', storeAsObject)

// Test 2 would involve storing the candle in an array
candleEmitter.on('candle', storeAsArray)

//Container for the object version of candles
let objectOhlc = {}

//Container for the array version of candles
let arrayOhlc = {}

//Store a max 30 candles and delete older ones
let limit = 30

function storeAsObject(candle) {

    //measure the start time in nanoseconds
    const hrtime1 = process.hrtime()
    const start = hrtime1[0] * 1e9 + hrtime1[1]

    const { symbol, time } = candle;

    // Create the object structure to store the current symbol
    if (typeof objectOhlc[symbol] === 'undefined') objectOhlc[symbol] = {}

    // The timestamp of the latest candle is used as key with the pair to store this symbol
    objectOhlc[symbol][time] = candle;

    // Remove entries if we exceed the limit
    const keys = Object.keys(objectOhlc[symbol]);
    if (keys.length > limit) {
        for (let i = 0; i < (keys.length - limit); i++) {
            delete objectOhlc[symbol][keys[i]];
        }
    }

    //measure the end time in nano seocnds
    const hrtime2 = process.hrtime()
    const end = hrtime2[0] * 1e9 + hrtime2[1]

    console.log("Storing as objects", end - start, Object.keys(objectOhlc[symbol]).length)
}

function storeAsArray(candle) {

    //measure the start time in nanoseconds
    const hrtime1 = process.hrtime()
    const start = hrtime1[0] * 1e9 + hrtime1[1]

    const { symbol, time } = candle;
    if (typeof arrayOhlc[symbol] === 'undefined') arrayOhlc[symbol] = []

    //Get the bunch of candles currently stored
    const candles = arrayOhlc[symbol];

    //Get the last candle if available
    const lastCandle = candles[candles.length - 1] || {};

    // Add a new entry for the newly arrived candle if it has a different timestamp from the latest one we storeds
    if (time !== lastCandle.time) {
        candles.push(candle);
    }

    //If our newly arrived candle has the same timestamp as the last stored candle, update the last stored candle
    else {
        candles[candles.length - 1] = candle

An .axd file is a HTTP Handler file. There are two types of .axd files.

1. ScriptResource.axd
2. WebResource.axd

These are files which are generated at runtime whenever you use ScriptManager in your Web app. This is being generated only once when you deploy it on the server.

Simply put the ScriptResource.AXD contains all of the clientside javascript routines for Ajax. Just because you include a scriptmanager that loads a script file it will never appear as a ScriptResource.AXD - instead it will be merely passed as the .js file you send if you reference a external script file. If you embed it in code then it may merely appear as part of the html as a tag and code but depending if you code according to how the ToolKit handles it - may or may not appear as as a ScriptResource.axd. ScriptResource.axd is only introduced with AJAX and you will never see it elsewhere

And ofcourse it is necessary

Its also possible to use dynamic SQL and execute it with the exec command:

declare @sql  nvarchar(200), @count int
set @count = 10
set @sql = N'select top ' + cast(@count as nvarchar(4)) + ' * from table'
exec (@sql)

/"(?:[^"\\]|\\.)*"/

Works in The Regex Coach and PCRE Workbench.

Example of test in JavaScript:

    var s = ' function(){ return " Is big \\"problem\\", \\no? "; }';_x000D_
    var m = s.match(/"(?:[^"\\]|\\.)*"/);_x000D_
    if (m != null)_x000D_
        alert(m);

Accepted answer of Kapil is flawed, it will update more than one record if there are 2 or more than one records available with same timestamps, not a true top 1 query.

Trying to do the same thing consistently with arrays and hashes might just be a code smell, but, at the risk of my being branded as a codorous half-monkey-patcher, if you're looking for consistent behaviour, would this do the trick?:

class Hash
    def each_pairwise
        self.each { | x, y |
            yield [x, y]
        }
    end
end

class Array
    def each_pairwise
        self.each_with_index { | x, y |
            yield [y, x]
        }
    end
end

["a","b","c"].each_pairwise { |x,y|
    puts "#{x} => #{y}"
}

{"a" => "Aardvark","b" => "Bogle","c" => "Catastrophe"}.each_pairwise { |x,y|
    puts "#{x} => #{y}"
}

From the Maven Doc:

• compile

  This is the default scope, used if none is specified. Compile dependencies are available in all classpaths of a project. Furthermore, those dependencies are propagated to dependent projects.

• provided

  This is much like compile, but indicates you expect the JDK or a container to provide the dependency at runtime. For example, when building a web application for the Java Enterprise Edition, you would set the dependency on the Servlet API and related Java EE APIs to scope provided because the web container provides those classes. This scope is only available on the compilation and test classpath, and is not transitive.

Recap:

• dependencies are not transitive (as you mentioned)
• provided scope is only available on the compilation and test classpath, whereas compile scope is available in all classpaths.
• provided dependencies are not packaged

Use an ordered broadcast. See http://android-developers.blogspot.nl/2011/01/processing-ordered-broadcasts.html

In your activity, register a receiver in onStart, unregister in onStop. Now when for example a service needs to handle something that the activity might be able to do better, send an ordered broadcast from the service (with a default handler in the service itself). You can now respond in the activity when it is running. The service can check the result data to see if the broadcast was handled, and if not take appropriate action.

Extending String native prototype:

if (!String.prototype.contains) {
    Object.defineProperty(String.prototype, 'contains', {
        value(patterns) {
            if (!Array.isArray(patterns)) {
                return false;
            }

            let value = 0;
            for (let i = 0; i < patterns.length; i++) {
                const pattern = patterns[i];
                value = value + this.includes(pattern);
            }
            return (value === 1);
        }
    });
}

Allowing you to do things like:

console.log('Hi, hope you like this option'.toLowerCase().contains(["hello", "hi", "howdy"])); // True

Did you try InputMethodManager.SHOW_IMPLICIT in first window.

and for hiding in second window use InputMethodManager.HIDE_IMPLICIT_ONLY

EDIT :

If its still not working then probably you are putting it at the wrong place. Override onFinishInflate() and show/hide there.

@override
public void onFinishInflate() {
     /* code to show keyboard on startup */
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);
}

javascript:document.getElementsByClassName("video-stream html5-main-video")[0].playbackRate = 0.1;

you can put any number here just don't go to far so you don't overun your computer.

Ok, instead of identifying players by name track with sockets through which they have connected. You can have a implementation like

Server

var allClients = [];
io.sockets.on('connection', function(socket) {
   allClients.push(socket);

   socket.on('disconnect', function() {
      console.log('Got disconnect!');

      var i = allClients.indexOf(socket);
      allClients.splice(i, 1);
   });
});

Hope this will help you to think in another way

I've gotten same problem. The servers logs showed:

DEBUG: <-- origin: null

I've investigated that and it occurred that this is not populated when I've been calling from file from local drive. When I've copied file to the server and used it from server - the request worked perfectly fine

Try this one:

System.DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")

Do not use primitives in your Entity classes, use instead their respective wrappers. That will fix this problem.

Out of your Entity classes you can use the != null validation for the rest of your code flow.

This is a prompt to create a bunch of object, such as sp_help_diagram (?), that do not exist.

This should have nothing to do with the owner of the db.

Is this what you're looking for?

if (request instanceof HttpServletRequest) {

If you want to center the content horizontally and vertically, but don't know in prior how high your page will be, you have to you use JavaScript.

HTML:

<body>
    <div id="content">...</div>

CSS:

#content {
    max-width: 1000px;
    margin: auto;
    left: 1%;
    right: 1%;
    position: absolute;
}

JavaScript (using jQuery):

$(function() {
    $(window).on('resize', function resize()  {
        $(window).off('resize', resize);
        setTimeout(function () {
            var content = $('#content');
            var top = (window.innerHeight - content.height()) / 2;
            content.css('top', Math.max(0, top) + 'px');
            $(window).on('resize', resize);
        }, 50);
    }).resize();
});

Using merge and renaming your t vector as tt (see the PS of Andrie) :

merge(tt,z,by="row.names",all.x=TRUE)[,-(5:8)]

Now if you would work with dataframes instead of matrices, this would even become a whole lot easier :

z <- as.data.frame(z)
tt <- as.data.frame(tt)
merge(tt,z["symbol"],by="row.names",all.x=TRUE)

Determine if property is existing (but is not a falsy value):

if (typeof query !== 'undefined' && query !== null){
   doStuff();
}

Usually using

if (query){
   doStuff();
}

is sufficient. Please note that:

if (!query){
   doStuff();
}

doStuff() will execute even if query was an existing variable with falsy value (0, false, undefined or null)

Btw, there's a sexy coffeescript way of doing this:

if object?.property? then doStuff()

which compiles to:

if ((typeof object !== "undefined" && object !== null ? object.property : void 0) != null) 

{
  doStuff();
}

Using testflight :

1) create the ipa file by development certificate

2) upload the ipa file on testflight

3) Now, to identify the device to be tested on , add the device id on apple account and refresh your development certificate. Download the updated certificate and upload it on testflight website. Check the device id you are getting.

4) Now email the ipa file to the testers.

5) While downloading the ipa file, if the testers are not getting any warnings, this means the device token + provisioning profile has been verified. So, the testers can now download the ipa file on device and do the testing job...

Apparently, gcc doesn't behave like the one described in The C Programming language, where it says that the command cc helloworld.c produces a file called a.out which can be run by typing a.out on the prompt.

A Unix hasn't behaved in that way by default (so you can just write the executable name without ./ at the front) in a long time. It's called a.exe, because else Windows won't execute it, as it gets file types from the extension.

Edit

This answer is now deprecated. See the answer by apsillers.

Since this is for a Chrome extension, you might as well use the standard DOM event - DOMSubtreeModified. See the support for this event across browsers. It has been supported in Chrome since 1.0.

$("#someDiv").bind("DOMSubtreeModified", function() {
    alert("tree changed");
});

See a working example here.

A little bit off topic maybe, but for modern browsers (IE9 and newer) you can use the css odd/even selectors to achieve want you want.

tr:nth-child(even) { /* your alt-row stuff */}
tr:nth-child(odd) { /* the other rows */ }

or

tr { /* all table rows */ }
tr:nth-child(even) { /* your alt-row stuff */}

No, cross-browser form custimization is very hard if not impossible to get it right for all browsers. If you really care about the appearance of those widgets you should use a javascript implementation.

Neater still, instead of the typical href="#" or href="javascript:void" or href="whatever", I think this makes much more sense:

var el = document.getElementById('foo');
el.onclick = showFoo;


function showFoo() {
  alert('I am foo!');
  return false;
}

<a href="no-javascript.html" title="Get some foo!" id="foo">Show me some foo</a>

If Javascript fails, there is some feedback. Furthermore, erratic behavior (page jumping in the case of href="#", visiting the same page in the case of href="") is eliminated.

I stumbled around in the bits and bytes and created an extension that I later found out works very similar to @rintaro's answer. It's used like this:

enum E : EnumCollection {
    case A, B, C
}

Array(E.cases())    // [A, B, C]

What's remarkable is that it's usable on any enum without associated values. Note that this doesn't work for enums that have no cases.

As with @rintaro's answer, this code uses the underlying representation of an enum. This representation isn't documented and might change in the future, which would break it. I don't recommend the usage of this in production.

Code (Swift 2.2, Xcode 7.3.1, not working on Xcode 10):

protocol EnumCollection : Hashable {}
extension EnumCollection {
    static func cases() -> AnySequence<Self> {
        typealias S = Self
        return AnySequence { () -> AnyGenerator<S> in
            var raw = 0
            return AnyGenerator {
                let current : Self = withUnsafePointer(&raw) { UnsafePointer($0).memory }
                guard current.hashValue == raw else { return nil }
                raw += 1
                return current
            }
        }
    }
}

Code (Swift 3, Xcode 8.1, not working on Xcode 10):

protocol EnumCollection : Hashable {}
extension EnumCollection {
    static func cases() -> AnySequence<Self> {
        typealias S = Self
        return AnySequence { () -> AnyIterator<S> in
            var raw = 0
            return AnyIterator {
                let current : Self = withUnsafePointer(to: &raw) { $0.withMemoryRebound(to: S.self, capacity: 1) { $0.pointee } }
                guard current.hashValue == raw else { return nil }
                raw += 1
                return current
            }
        }
    }
}

I have no idea why I need typealias, but the compiler complains without it.

Here is OpenSSL example of calculating sha-1 digest using BIO:

#include <openssl/bio.h>
#include <openssl/evp.h>

std::string sha1(const std::string &input)
{
    BIO * p_bio_md  = nullptr;
    BIO * p_bio_mem = nullptr;

    try
    {
        // make chain: p_bio_md <-> p_bio_mem
        p_bio_md = BIO_new(BIO_f_md());
        if (!p_bio_md) throw std::bad_alloc();
        BIO_set_md(p_bio_md, EVP_sha1());

        p_bio_mem = BIO_new_mem_buf((void*)input.c_str(), input.length());
        if (!p_bio_mem) throw std::bad_alloc();
        BIO_push(p_bio_md, p_bio_mem);

        // read through p_bio_md
        // read sequence: buf <<-- p_bio_md <<-- p_bio_mem
        std::vector<char> buf(input.size());
        for (;;)
        {
            auto nread = BIO_read(p_bio_md, buf.data(), buf.size());
            if (nread  < 0) { throw std::runtime_error("BIO_read failed"); }
            if (nread == 0) { break; } // eof
        }

        // get result
        char md_buf[EVP_MAX_MD_SIZE];
        auto md_len = BIO_gets(p_bio_md, md_buf, sizeof(md_buf));
        if (md_len <= 0) { throw std::runtime_error("BIO_gets failed"); }

        std::string result(md_buf, md_len);

        // clean
        BIO_free_all(p_bio_md);

        return result;
    }
    catch (...)
    {
        if (p_bio_md) { BIO_free_all(p_bio_md); }
        throw;
    }
}

Though it's longer than just calling SHA1 function from OpenSSL, but it's more universal and can be reworked for using with file streams (thus processing data of any length).

Use typings to access node functions from TypeScript:

typings install env~node --global

If you don't have typings install it:

npm install typings --global

Define this function (say in ~/.bashrc):

time::clock() {
    [ -z "$ts" ]&&{ ts=`date +%s%N`;return;}||te=`date +%s%N`
    printf "%6.4f" $(echo $((te-ts))/1000000000 | bc -l)
    unset ts te
}

Now you can measure time of parts of your scripts:

$ cat script.sh
# ... code ...
time::clock
sleep 0.5
echo "Total time: ${time::clock}"
# ... more code ...

$ ./script.sh
Total time: 0.5060

very useful to find execution bottlenecks.

This command works like a charm for me:

for /r "$(SolutionDir)libraries" %%f in (*.dll, *.exe) do @xcopy "%%f" "$(TargetDir)"

It recursively copies every dll and exe file from MySolutionPath\libraries into the bin\debug or bin\release.

GOOGLEFINANCE can have a 20 minutes delay, so refreshing every minute would not really help.

Instead of GOOGLEFINANCE you can use different source. I'm using this RealTime stock prices(I tried a couple but this is the easiest by-far to implement. They have API that retuen JSON { Name: CurrentPrice }

Here's a little script you can use in Google Sheets(Tools->Script Editor)

function GetStocksPrice() {      
   var url = 'https://financialmodelingprep.com/api/v3/stock/real-time- 
   price/AVP,BAC,CHK,CY,GE,GPRO,HIMX,IMGN,MFG,NIO,NMR,SSSS,UCTT,UMC,ZNGA';
   var response = UrlFetchApp.fetch(url);

   // convert json string to json object
   var jsonSignal = JSON.parse(response);    

  // define an array of all the object keys
  var headerRow = Object.keys(jsonSignal);
  // define an array of all the object values
  var values = headerRow.map(function(key){ return jsonSignal[key]});   
  var data = values[0];

  // get sheet by ID -  
  // you can get the sheet unqiue ID from the your current sheet url
  var jsonSheet = SpreadsheetApp.openById("Your Sheet UniqueID");  
  //var name = jsonSheet.getName();

  var sheet = jsonSheet.getSheetByName('Sheet1'); 

  // the column to put the data in -> Y
  var letter = "F";

  // start from line 
  var index = 4;
  data.forEach(function( row, index2 ) { 

     var keys = Object.keys(row);
     var value2 = row[keys[1]];            

     // set value loction
     var cellXY = letter +  index;      
     sheet.getRange(cellXY).setValue(value2);  
  
     index = index + 1;    
 });  
}

Now you need to add a trigger that will execute every minute.

1. Go to Project Triggers -> click on the Watch icon next to the Save icon
2. Add Trigger
3. In -> Choose which function to run -> GetStocksPrice
4. In -> Select event source -> Time-driven
5. In -> Select type of time based trigger -> Minutes timer
6. In -> Select minute interval -> Every minute

And your set :)

If you just want to see the image on your local browser, this can be done if you have a server running locally. You just need to reference the local server via http (not file://), like:

http://localhost/my_picture.jpg

if picture.jpg is in your local server's webroot folder. You can do this for any site if you open your browser's developer tools and change the img element's src attribute to the local server's URL for the image. If you have access to the HTML of your site, then change it there. But obviously if someone not on your local computer/server accesses the site, they will get a broken image unless they happen to be running a local server as well and have an image with the same filename, which would be weird.

I found this much easier(https://docs.oracle.com/javase/tutorial/datetime/iso/enum.html)

    Month month = Month.of(calendar.get(Calendar.MONTH));       
    Locale locale = Locale.getDefault();
    System.out.println(month.getDisplayName(TextStyle.FULL, locale));
    System.out.println(month.getDisplayName(TextStyle.NARROW, locale));
    System.out.println(month.getDisplayName(TextStyle.SHORT, locale));
}

A hack the I've used on Solaris 9 and Linux and which works fine for both of them:

ps -o user= -p $$ | awk '{print $1}'

This snippet prints the name of the user with the current EUID.

NOTE: you need Bash as the interpreter here.

On Solaris you have problems with methods, described above:

• id does not accept the -u and -n parameters (so you will have to parse the output)
• whoami does not exist (by default)
• who am I prints owner of current terminal (ignores EUID)
• $USER variable is set correctly only after reading profile files (for example, /etc/profile)

static class MyClass
{
   public const string NewLine="\n";
}

string x = "first line" + MyClass.NewLine + "second line"

#!/bin/bash

The above will give you the total count of lines of code (blank lines removed) for a project (current folder and all subfolders recursively).

In the above "./blog" "./punbb" "./js/3rdparty" and "./pma" are folders I blacklist as I didn't write the code in them. Also .php, .as, .sql, .css, .js are the extensions of the files being looked at. Any files with a different extension are ignored.

I think it's too late to answer this question, but actually there is a way to achieve your goal. You just need to add the following line to your checkbox:

android:button="@null"
android:drawableRight="?android:attr/listChoiceIndicatorMultiple"

You can use your customized drawable for checkbox as well.

And for a radioButton:

android:button="@null"
android:drawableRight="@android:drawable/btn_radio"

And if you want to do it programmatically:

Define a layout and name it RightCheckBox and copy the following lines :

<?xml version="1.0" encoding="utf-8"?>
<CheckBox xmlns:android="http://schemas.android.com/apk/res/android"
    android:text="hello"
    android:layout_width="match_parent" 
    android:layout_height="match_parent"
    android:button="@null"
    android:drawableRight="?android:attr/listChoiceIndicatorMultiple"/>

and when you need to add it programmatically you just need to inflate it to a CheckBox and add it to the root view.

CheckBox cb = (CheckBox)((LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE)).inflate(R.layout.check_right_checkbox,null);
rootView.addView(cb);

try this

http://www.ehow.com/how_6613143_convert-xml-code-sql.html

for downloading the tool http://www.xml-converter.com/

you can check that by either isset() or empty() (its check explicit isset) weather check box is checked or not

for example

  <input type='checkbox' name='Mary' value='2' id='checkbox' />

here you can check by

if (isset($_POST['Mary'])) {
    echo "checked!";
}

or

if (!empty($_POST['Mary'])) {
    echo "checked!";
}

the above will check only one if you want to do for many than you can make an array instead writing separate for all checkbox try like

<input type="checkbox" name="formDoor[]" value="A" />Acorn Building<br />
<input type="checkbox" name="formDoor[]" value="B" />Brown Hall<br />
<input type="checkbox" name="formDoor[]" value="C" />Carnegie Complex<br />

php

  $aDoor = $_POST['formDoor'];
  if(empty($aDoor))
  {
    echo("You didn't select any buildings.");
  }
  else
  {
    $N = count($aDoor);
    echo("You selected $N door(s): ");
    for($i=0; $i < $N; $i++)
    {
      echo htmlspecialchars($aDoor[$i] ). " ";
    }
  }

-- Here is the solution:

create procedure GetOrderForCustomers(@CustID varchar(20))

as

begin

select * from orders

where customerid = ISNULL(@CustID, '')

end

-- That's it

If your purpose of limiting text count is to ensure that text will fit into a UILabel elsewhere, I'd avoid using character count. It breaks down with some emoji (trying to truncate a double size emoji will likely crash your app). It's also an issue with some languages like Japanese and Chinese, which have a two-step input process where a simple count just won't work.

I built out a UITextField drop-in subclass (MPC_CharacterLimitedTextField on github). You feed it the expected output label width and it will handle all languages, emoji, and pasting issues. It will harvest only as many full characters that will fit into the label, regardless of the character count. There's a demo in the project so you can test it to see if it's what you need. Hope it will help anybody who was having the same problems with output length that I was.

Can anyone give me a brief explanation...

Sure.

ORM stands for "Object to Relational Mapping" where

• The Object part is the one you use with your programming language ( python in this case )

• The Relational part is a Relational Database Manager System ( A database that is ) there are other types of databases but the most popular is relational ( you know tables, columns, pk fk etc eg Oracle MySQL, MS-SQL )

• And finally the Mapping part is where you do a bridge between your objects and your tables.

In applications where you don't use a ORM framework you do this by hand. Using an ORM framework would allow you do reduce the boilerplate needed to create the solution.

So let's say you have this object.

 class Employee:
      def __init__( self, name ): 
          self.__name = name

       def getName( self ):
           return self.__name

       #etc.

and the table

   create table employee(
          name varcar(10),
          -- etc  
    )

Using an ORM framework would allow you to map that object with a db record automagically and write something like:

   emp = Employee("Ryan")

   orm.save( emp )

And have the employee inserted into the DB.

git revert makes a new commit

git revert simply creates a new commit that is the opposite of an existing commit.

It leaves the files in the same state as if the commit that has been reverted never existed. For example, consider the following simple example:

$ cd /tmp/example
$ git init
Initialized empty Git repository in /tmp/example/.git/
$ echo "Initial text" > README.md
$ git add README.md
$ git commit -m "initial commit"
[master (root-commit) 3f7522e] initial commit
 1 file changed, 1 insertion(+)
 create mode 100644 README.md
$ echo "bad update" > README.md 
$ git commit -am "bad update"
[master a1b9870] bad update
 1 file changed, 1 insertion(+), 1 deletion(-)

In this example the commit history has two commits and the last one is a mistake. Using git revert:

$ git revert HEAD
[master 1db4eeb] Revert "bad update"
 1 file changed, 1 insertion(+), 1 deletion(-)

There will be 3 commits in the log:

$ git log --oneline
1db4eeb Revert "bad update"
a1b9870 bad update
3f7522e initial commit

So there is a consistent history of what has happened, yet the files are as if the bad update never occured:

cat README.md 
Initial text

It doesn't matter where in the history the commit to be reverted is (in the above example, the last commit is reverted - any commit can be reverted).

Closing questions

do you have to do something else after?

A git revert is just another commit, so e.g. push to the remote so that other users can pull/fetch/merge the changes and you're done.

Do you have to commit the changes revert made or does revert directly commit to the repo?

git revert is a commit - there are no extra steps assuming reverting a single commit is what you wanted to do.

Obviously you'll need to push again and probably announce to the team.

Indeed - if the remote is in an unstable state - communicating to the rest of the team that they need to pull to get the fix (the reverting commit) would be the right thing to do :).

Using the Schwartzian transform from Perl,

py = [{'name':'Homer', 'age':39}, {'name':'Bart', 'age':10}]

do

sort_on = "name"
decorated = [(dict_[sort_on], dict_) for dict_ in py]
decorated.sort()
result = [dict_ for (key, dict_) in decorated]

gives

>>> result
[{'age': 10, 'name': 'Bart'}, {'age': 39, 'name': 'Homer'}]

More on the Perl Schwartzian transform:

In computer science, the Schwartzian transform is a Perl programming idiom used to improve the efficiency of sorting a list of items. This idiom is appropriate for comparison-based sorting when the ordering is actually based on the ordering of a certain property (the key) of the elements, where computing that property is an intensive operation that should be performed a minimal number of times. The Schwartzian Transform is notable in that it does not use named temporary arrays.

In my case I got this error because the API I used could return the data either in XML or in JSON format. When I tested it using a browser, it defaulted to the XML format, but when I invoked the same call from a Java application, the API returned the JSON formatted response, that naturally triggered a parsing error.

Ok, it seems that some versions of PHP have a limitation of length of GET params:

Please note that PHP setups with the suhosin patch installed will have a default limit of 512 characters for get parameters. Although bad practice, most browsers (including IE) supports URLs up to around 2000 characters, while Apache has a default of 8000.

To add support for long parameters with suhosin, add suhosin.get.max_value_length = <limit> in php.ini

Promises can be "handled" after they are rejected. That is, one can call a promise's reject callback before providing a catch handler. This behavior is a little bothersome to me because one can write...

var promise = new Promise(function(resolve) {
kjjdjf(); // this function does not exist });

... and in this case, the Promise is rejected silently. If one forgets to add a catch handler, code will continue to silently run without errors. This could lead to lingering and hard-to-find bugs.

In the case of Node.js, there is talk of handling these unhandled Promise rejections and reporting the problems. This brings me to ES7 async/await. Consider this example:

async function getReadyForBed() {
  let teethPromise = brushTeeth();
  let tempPromise = getRoomTemperature();

  // Change clothes based on room temperature
  let temp = await tempPromise;
  // Assume `changeClothes` also returns a Promise
  if(temp > 20) {
    await changeClothes("warm");
  } else {
    await changeClothes("cold");
  }

  await teethPromise;
}

In the example above, suppose teethPromise was rejected (Error: out of toothpaste!) before getRoomTemperature was fulfilled. In this case, there would be an unhandled Promise rejection until await teethPromise.

My point is this... if we consider unhandled Promise rejections to be a problem, Promises that are later handled by an await might get inadvertently reported as bugs. Then again, if we consider unhandled Promise rejections to not be problematic, legitimate bugs might not get reported.

Thoughts on this?

This is related to the discussion found in the Node.js project here:

Default Unhandled Rejection Detection Behavior

if you write the code this way:

function getReadyForBed() {
  let teethPromise = brushTeeth();
  let tempPromise = getRoomTemperature();

  // Change clothes based on room temperature
  return Promise.resolve(tempPromise)
    .then(temp => {
      // Assume `changeClothes` also returns a Promise
      if (temp > 20) {
        return Promise.resolve(changeClothes("warm"));
      } else {
        return Promise.resolve(changeClothes("cold"));
      }
    })
    .then(teethPromise)
    .then(Promise.resolve()); // since the async function returns nothing, ensure it's a resolved promise for `undefined`, unless it's previously rejected
}

When getReadyForBed is invoked, it will synchronously create the final (not returned) promise - which will have the same "unhandled rejection" error as any other promise (could be nothing, of course, depending on the engine). (I find it very odd your function doesn't return anything, which means your async function produces a promise for undefined.

If I make a Promise right now without a catch, and add one later, most "unhandled rejection error" implementations will actually retract the warning when i do later handle it. In other words, async/await doesn't alter the "unhandled rejection" discussion in any way that I can see.

to avoid this pitfall please write the code this way:

async function getReadyForBed() {
  let teethPromise = brushTeeth();
  let tempPromise = getRoomTemperature();

  // Change clothes based on room temperature
  var clothesPromise = tempPromise.then(function(temp) {
    // Assume `changeClothes` also returns a Promise
    if(temp > 20) {
      return changeClothes("warm");
    } else {
      return changeClothes("cold");
    }
  });
  /* Note that clothesPromise resolves to the result of `changeClothes`
     due to Promise "chaining" magic. */

  // Combine promises and await them both
  await Promise.all(teethPromise, clothesPromise);
}

Note that this should prevent any unhandled promise rejection.

JDK version 9:

sudo apt install openjdk-9-jre

JDK version 8:

sudo apt install openjdk-8-jre

Open Jenkins configuration file:

sudo vi /etc/init.d/jenkins

Finally, append path to the new java executable (line 16):

PATH=/bin:/usr/bin:/sbin:/usr/sbin:/usr/lib/jvm/java-8-openjdk-amd64/bin/

Similar to using ifilter, you could use a generator expression:

>>> (x for x in xrange(10) if x > 5).next()
6

In either case, you probably want to catch StopIteration though, in case no elements satisfy your condition.

Technically speaking, I suppose you could do something like this:

>>> foo = None
>>> for foo in (x for x in xrange(10) if x > 5): break
... 
>>> foo
6

It would avoid having to make a try/except block. But that seems kind of obscure and abusive to the syntax.

You can try viewport units (CSS3):

div { 
  height: 95vh; 
  width: 95vw; 
}

Browser support

Basically it contains all the attributes which describe the object in question. It can be used to alter or read the attributes. Quoting from the documentation for __dict__

A dictionary or other mapping object used to store an object's (writable) attributes.

Remember, everything is an object in Python. When I say everything, I mean everything like functions, classes, objects etc (Ya you read it right, classes. Classes are also objects). For example:

def func():
    pass

func.temp = 1

print(func.__dict__)

class TempClass:
    a = 1
    def temp_function(self):
        pass

print(TempClass.__dict__)

will output

{'temp': 1}
{'__module__': '__main__', 
 'a': 1, 
 'temp_function': <function TempClass.temp_function at 0x10a3a2950>, 
 '__dict__': <attribute '__dict__' of 'TempClass' objects>, 
 '__weakref__': <attribute '__weakref__' of 'TempClass' objects>, 
 '__doc__': None}

Building on Der Wolfs tip, I uninstalled the Oracle client and installed it again, right-clicking on the setup program, and running it as Administrator. It worked.

In order to save the Fragment state you need to implement onSaveInstanceState(): "Also like an activity, you can retain the state of a fragment using a Bundle, in case the activity's process is killed and you need to restore the fragment state when the activity is recreated. You can save the state during the fragment's onSaveInstanceState() callback and restore it during either onCreate(), onCreateView(), or onActivityCreated(). For more information about saving state, see the Activities document."

I have been researching a lot about the EOF signal. In the book on Programming in C by Dennis Ritchie it is first encountered while introducing putchar() and getchar() commands. It basically marks the end of the character string input.

For eg. Let us write a program that seeks two numerical inputs and prints their sum. You'll notice after each numerical input you press Enter to mark the signal that you have completed the iput action. But while working with character strings Enter is read as just another character ['\n': newline character]. To mark the termination of input you enter ^Z(Ctrl + Z on keyboard) in a completely new line and then enter. That signals the next lines of command to get executed.

#include <stdio.h>

int main()
{
char c;
int i = 0;
printf("INPUT:\t");
c = getchar();

while (c != EOF)
{
   ++i;
   c = getchar();
   
};

printf("NUMBER OF CHARACTERS %d.", i);

return 0;}

The above is the code to count number of characters including '\n'(newline) and '\t'( space) characters. If you don't wanna count the newline characters do this :

#include <stdio.h>

int main()
{
char c;
int i = 0;
printf("INPUT:\t");
c = getchar();

while (c != EOF)
{
    if (c != '\n')
    {
        ++i;
    }

    c = getchar();
    };

printf("NUMBER OF CHARACTERS %d.", i);

return 0;}. 

NOW THE MAIN THINK HOOW TO GIVE INPUT. IT'S SIMPLE: Write all the story you want then go in a new line and enter ^Z and then enter again.

I know this question posted long time ago.

I had similar problem few days ago, passing value from web service in json format and place it in table cell contentText.

Because value is passed in format, for example, "text row1\r\ntext row2" and so on.

For new line in textContent You have to use \r\n and, finally, I had to use css white-space: pre-line; (Text will wrap when necessary, and on line breaks) and everything goes fine.

Or, You can use only white-space: pre; and then text will wrap only on line breaks (in this case \r\n).

So, there is example how to solve it with wrapping text only on line breaks :

var h1 = document.createElement("h1");_x000D_
_x000D_
//setting this css style solving problem with new line in textContent_x000D_
h1.setAttribute('style', 'white-space: pre;');_x000D_
_x000D_
//add \r\n in text everywhere You want for line-break (new line)_x000D_
h1.textContent = "This is a very long string and I would like to insert a carriage return \r\n...";_x000D_
h1.textContent += "moreover, I would like to insert another carriage return \r\n...";_x000D_
h1.textContent += "so this text will display in a new line";_x000D_
_x000D_
document.body.appendChild(h1);

If you search for an image base-64 converter, you can embed some small image texture files as code into your @import url('') section of code. It will look like a lot of code; but at least all your data is now stored locally - rather than having to call a separate resource to load the image.

I've just added a solution here (is there a way in git to list all deleted files in the repository?) for finding the commits of deleted files by using a regexp:

git log --diff-filter=D --summary | sed -n '/^commit/h;/\/some_dir\//{G;s/\ncommit \(.*\)/ \1/gp}'

This returns everything deleted within a directory named some_dir (cascading). Any sed regexp there where \/some_dir\/ is will do.

OSX (thanks to @triplee and @keif)

git log --diff-filter=D --summary | sed -n -e '/^commit/h' -e '\:/:{' -e G -e 's/\ncommit \(.*\)/ \1/gp' -e }

You can use Spring SimpleKey class

@Cacheable(value = "bookCache", key = "new org.springframework.cache.interceptor.SimpleKey(#isbn, #checkWarehouse)")

simple :

if($_FILES['cover_image']['error'] > 0)
    // cover_image is empty

Or if you want a ripple pulse effect, you could use this:

http://jsfiddle.net/Fy8vD/3041/

.gps_ring {
     border: 2px solid #fff;
     -webkit-border-radius: 50%;
     height: 18px;

It means that you have a memory error. You may be trying to free a pointer that wasn't allocated by malloc (or delete an object that wasn't created by new) or you may be trying to free/delete such an object more than once. You may be overflowing a buffer or otherwise writing to memory to which you shouldn't be writing, causing heap corruption.

Any number of programming errors can cause this problem. You need to use a debugger, get a backtrace, and see what your program is doing when the error occurs. If that fails and you determine you have corrupted the heap at some previous point in time, you may be in for some painful debugging (it may not be too painful if the project is small enough that you can tackle it piece by piece).

Using Java 8 try with resources:

    StringBuilder stringBuilder = new StringBuilder();
    try(BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(request.getInputStream()))) {
        char[] charBuffer = new char[1024];
        int bytesRead;
        while ((bytesRead = bufferedReader.read(charBuffer)) > 0) {
            stringBuilder.append(charBuffer, 0, bytesRead);
        }
    }

Normally, encryption functions take

encrypt(const void *ptr, size_t bufferSize);

as arguments. You can pass c_str and length directly:

encrypt(strng.c_str(), strng.length());

This way, extra space is allocated or wasted.

This is usually caused by truncation (the incoming value is too large to fit in the destination column). Unfortunately SSIS will not tell you the name of the offending column. I use a third-party component to get this information: http://naseermuhammed.wordpress.com/tips-tricks/getting-error-column-name-in-ssis/

If your set command supports the /p switch, then you can pipe input that way.

set /p VAR1=<test.txt
set /? |find "/P"

The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

This has the added benefit of working for un-registered file types (which the accepted answer does not).

<input type="text" name="PhoneNumber" pattern="[0-9]{10}" title="Phone number">

Using this code, the input to the text field limits to enter only digits. Pattern is the new attribute available in HTML 5.

Since no one gave this answer, I would also like to add that, you can just add the jdbc driver file(mysql-connector-java-5.1.27-bin.jar in my case) to the lib folder of your server(Tomcat in my case). Restart the server and it should work.

There's actually a very good blog post that lists pro's and cons of three different approaches to this problem by Martyn Davies. You can read it at https://sendgrid.com/blog/embedding-images-emails-facts/.

I'd like to add a fourth approach using CSS background images.

Add

<div id="myImage"></div>

to your e-mail body and a css class like:

#myImage {
    background-image:  url('data:image/png;base64,iVBOR...[some more encoding]...rkggg==');
    width: [the-actual-image-width];
    height: [the-actual-image-height];
}

<div id="map" style="width:100%;height:500px"></div>

<script>
function myMap() {
  var myCenter = new google.maps.LatLng(51.508742,-0.120850);
  var mapCanvas = document.getElementById("map");
  var mapOptions = {center: myCenter, zoom: 5};
  var map = new google.maps.Map(mapCanvas, mapOptions);
  var marker = new google.maps.Marker({position:myCenter});
  marker.setMap(map);
}
</script>

<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBu-916DdpKAjTmJNIgngS6HL_kDIKU0aU&callback=myMap"></script>

I struggled to understand the proxy settings for websockets for https therefore let me put clarity here what i realized.

First you need to enable proxy and proxy_wstunnel apache modules and the apache configuration file will look like this.

<IfModule mod_ssl.c>
    <VirtualHost _default_:443>
      ServerName www.example.com
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/your_project_public_folder

      SSLEngine on
      SSLCertificateFile    /etc/ssl/certs/path_to_your_ssl_certificate
      SSLCertificateKeyFile /etc/ssl/private/path_to_your_ssl_key

      <Directory /var/www/your_project_public_folder>
              Options Indexes FollowSymLinks
              AllowOverride All
              Require all granted
              php_flag display_errors On
      </Directory>
      ProxyRequests Off 
      ProxyPass /wss/  ws://example.com:port_no

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
    </VirtualHost>
</IfModule>

in your frontend application use the url "wss://example.com/wss/" this is very important mostly if you are stuck with websockets you might be making mistake in the front end url. You probably putting url wrongly like below.

wss://example.com:8080/wss/ -> port no should not be mentioned
ws://example.com/wss/ -> url should start with wss only.
wss://example.com/wss -> url should end with / -> most important

also interesting part is the last /wss/ is same as proxypass value if you writing proxypass /ws/ then in the front end you should write /ws/ in the end of url.

Sheet.getPhysicalNumberOfRows() does not involve some empty rows. If you want to loop for all rows, do not use this to know the loop size.

dir /ad /b /s will give the required answer.

If you load you table file with dtype=str
or convert column type to string df['a'] = df['a'].astype(str)
then you can use such approach:

df['a']= 'col' + df['a'].str[:]

This approach allows prepend, append, and subset string of df.
Works on Pandas v0.23.4, v0.24.1. Don't know about earlier versions.

There are some good answers on how to get started on doing this. But there are some things to keep in mind:

• What if the instance is nested inside a large data structure?
• What if also want the class name?
• What if you want to deserialize the instance?
• What if you're using __slots__ instead of __dict__?
• What if you just don't want to do it yourself?

json-tricks is a library (that I made and others contributed to) which has been able to do this for quite a while. For example:

class MyTestCls:
    def __init__(self, **kwargs):
        for k, v in kwargs.items():
            setattr(self, k, v)

cls_instance = MyTestCls(s='ub', dct={'7': 7})

json = dumps(cls_instance, indent=4)
instance = loads(json)

You'll get your instance back. Here the json looks like this:

{
    "__instance_type__": [
        "json_tricks.test_class",
        "MyTestCls"
    ],
    "attributes": {
        "s": "ub",
        "dct": {
            "7": 7
        }
    }
}

If you like to make your own solution, you might look at the source of json-tricks so as not to forget some special cases (like __slots__).

It also does other types like numpy arrays, datetimes, complex numbers; it also allows for comments.

This command works

Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

Run it then agree to restart the computer when prompted.

I ran it in elevated permissions PowerShell on Windows 10, but it should also work on Win 8 or 7.

Here is what you are looking for:

String sDate = DateTime.Now.ToString();
DateTime datevalue = (Convert.ToDateTime(sDate.ToString()));

String dy = datevalue.Day.ToString();
String mn = datevalue.Month.ToString();
String yy = datevalue.Year.ToString();

OR

Alternatively, you can use split function to split string date into day, month and year here.

Hope, it will helps you... Cheers. !!

number_string = '0, 0, 0, 11, 0, 0, 0, 0, 0, 19, 0, 9, 0, 0, 0, 0, 0, 0, 11'

number_string = number_string.split(',')

number_string = [int(i) for i in number_string]

Or you can use .info() on the DF such as :

df.info(null_counts=True) which returns the number of non_null rows in a columns such as:

<class 'pandas.core.frame.DataFrame'>
Int64Index: 3276314 entries, 0 to 3276313
Data columns (total 10 columns):
n_matches                          3276314 non-null int64
avg_pic_distance                   3276314 non-null float64

Just need to put condition to execute task for specific distribution

- name: Creates directory
  file: path=/src/www state=directory
  when: ansible_distribution == 'Debian'

FOR EXAMPLE YOU HAVE RECIEVED JASON DATA FROM SERVER.

                var obj = JSON.parse(msg);
                var tableString ="<table id='tbla'>";
                tableString +="<th><td>Name<td>City<td>Birthday</th>";


                for (var i=0; i<obj.length; i++){
                    //alert(obj[i].name);
                    tableString +=gg_stringformat("<tr><td>{0}<td>{1}<td>{2}</tr>",obj[i].name, obj[i].age, obj[i].birthday);
                }
                tableString +="</table>";
                alert(tableString);
                $('#divb').html(tableString);

HERE IS THE CODE FOR gg_stringformat

function gg_stringformat() {
var argcount = arguments.length,
    string,
    i;

if (!argcount) {
    return "";
}
if (argcount === 1) {
    return arguments[0];
}
string = arguments[0];
for (i = 1; i < argcount; i++) {
    string = string.replace(new RegExp('\\{' + (i - 1) + '}', 'gi'), arguments[i]);
}
return string;

}

1. Open your command prompt
2. Change directory to E:\Android\adt-bundle-windows-x86_64-20140702\adt-bundle-windows-x86_64-20140702\sdk\platform-tools
3. Enter below commands
4. adb -d shell
5. run-as com.your.packagename cat databases/database.db > /sdcard/database.db
6. Change directory to cd /sdcard to make sure database.db is there.
7. adb pull /sdcard/database.db or simply you can copy database.db from device .

Installing/Upgrading Python Using the Chocolatey Windows Package Manager

Let's say you have Python 2.7.16:

    C:\Windows\system32>python --version
    python2 2.7.16

...and you want to upgrade to the (now current) 3.x.y version. There is a simple way to install a parallel installation of Python 3.x.y using a Windows package management tool.

Now that modern Windows has package management, just like Debian Linux distributions have apt-get, and RedHat has dnf: we can put it to work for us! It's called Chocolatey.

What's Chocolatey?

Chocolatey is a scriptable, command line tool that is based on .NET 4.0 and the nuget package manager baked into Visual Studio.

If you want to learn about Chocolatey and why to use it, which some here reading this might find particularly useful, go to https://chocolatey.org/docs/why

Installing Chocolatey

To get the Chocolatey Package Manager, you follow a process that is described at https://chocolatey.org/docs/installation#installing-chocolatey,

I'll summarize it for you here. There are basically two options: using the cmd prompt, or using the PowerShell prompt.

CMD Prompt Chocolatey Installation

Launch an administrative command prompt. On Windows 10, to do this:

• Windows+R
• Type cmd
• Press ctrl+shift+Enter

If you don't have administrator rights on the system, go to the Chocolatey website. You may not be completely out of luck and can perform a limited local install, but I won't cover that here.

• Copy the string below into your command prompt and type Enter:

@"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"

Chocolatey will be downloaded and installed for you as below:

Ensuring chocolatey commands are on the path
Ensuring chocolatey.nupkg is in the lib folder

Either Exit the CMD prompt or type the following command to reload the environment variables:

refreshenv

PowerShell Chocolatey Installation

If you prefer PowerShell to the cmd prompt, you can do this directly from there, however you will have to tell PowerShell to run with a proper script execution policy to get it to work. On Windows 10, the simplest way I have found to do this is to type the following into the Cortana search bar next to the Windows button:

PowerShell.exe

Next, right click on the 'Best Match' choice in the menu that pops up and select 'Run as Administrator'

Now that you're in PowerShell, hopefully running with Administrator privileges, execute the following to install Chocolatey:

Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

PowerShell will download Chocolatey for you and launch the installation. It only takes a few moments. It looks exactly like the CMD installation, save perhaps some fancy colored text.

Either Exit PowerShell or type the following command to reload the environment variables:

refreshenv

Upgrading Python

The choco command is the same whether you use PowerShell or the cmd prompt. Launch your favorite using the instructions as above. I'll use the administrator cmd prompt:

C:\WINDOWS\system32>choco upgrade python -y

Essentially, chocolatey will tell you "Hey, Python isn't installed" since you're coming from 2.7.x and it treats the 2.7 version as completely separate. It is only going to give you the most current version, 3.x.y (as of this writing, 3.7.2, but that will change in a few months):

Chocolatey v0.10.11
Upgrading the following packages:
python
By upgrading you accept licenses for the packages.

  python3 can be automatically uninstalled.
Environment Vars (like PATH) have changed. Close/reopen your shell to

 The upgrade of python3 was successful.
  Software installed as 'exe', install location is likely default.

python v3.x.y [Approved]
python package files upgrade completed. Performing other installation steps.
 The upgrade of python was successful.
  Software install location not explicitly set, could be in package or
  default install location if installer.

Chocolatey upgraded 2/2 packages.
 See the log for details (C:\ProgramData\chocolatey\logs\chocolatey.log).

Either exit out of the cmd/Powershell prompt and re-enter it, or use refreshenv then type py --version

C:\Windows\System32>refreshenv
Refreshing environment variables from registry for cmd.exe. Please wait...Finished..

C:\Windows\system32>py --version
Python 3.7.2

Note that the most recent Python install will now take over when you type Python at the command line. You can run either version by using the following commands:

py -2
Python 2.7.16 (v2.7.16:413a49145e, Mar  4 2019, 01:37:19) [MSC v.1500 64 bit (AMD64)] on win32

Type "help", "copyright", "credits" or "license" for more information.
>>>exit()
C:\>

From here I suggest you use the Python pip utility to install whatever packages you need. For example, let's say you wanted to install Flask. The commands below first upgrade pip, then install Flask

C:\>py -3 -m pip install --upgrade pip
