Cellpadding is the amount of space between the outer edges of the table cell and the content of the cell.

Cellspacing is the amount of space in between the individual table cells.

Update:

Improved and simplified version of previous directive (one instead of two) with same functionality:

.directive('myTestExpression', ['$parse', function ($parse) {
    return {
        restrict: 'A',
        require: 'ngModel',
        link: function (scope, element, attrs, ctrl) {
            var expr = attrs.myTestExpression;
            var watches = attrs.myTestExpressionWatch;

            ctrl.$validators.mytestexpression = function (modelValue, viewValue) {
                return expr == undefined || (angular.isString(expr) && expr.length < 1) || $parse(expr)(scope, { $model: modelValue, $view: viewValue }) === true;
            };

            if (angular.isString(watches)) {
                angular.forEach(watches.split(",").filter(function (n) { return !!n; }), function (n) {
                    scope.$watch(n, function () {
                        ctrl.$validate();
                    });
                });
            }
        }
    };
}])

Example usage:

<input ng-model="price1" 
       my-test-expression="$model > 0" 
       my-test-expression-watch="price2,someOtherWatchedPrice" />
<input ng-model="price2" 
       my-test-expression="$model > 10" 
       my-test-expression-watch="price1" 
       required />

Result: Mutually dependent test expressions where validators are executed on change of other's directive model and current model.

Test expression has local $model variable which you should use to compare it to other variables.

Previously:

I've made an attempt to improve @Plantface code by adding extra directive. This extra directive very useful if our expression needs to be executed when changes are made in more than one ngModel variables.

.directive('ensureExpression', ['$parse', function($parse) {
    return {
        restrict: 'A',
        require: 'ngModel',
        controller: function () { },
        scope: true,
        link: function (scope, element, attrs, ngModelCtrl) {
            scope.validate = function () {
                var booleanResult = $parse(attrs.ensureExpression)(scope);
                ngModelCtrl.$setValidity('expression', booleanResult);
            };

            scope.$watch(attrs.ngModel, function(value) {
                scope.validate();
            });
        }
    };
}])

.directive('ensureWatch', ['$parse', function ($parse) {
    return {
        restrict: 'A',
        require: 'ensureExpression',
        link: function (scope, element, attrs, ctrl) {
            angular.forEach(attrs.ensureWatch.split(",").filter(function (n) { return !!n; }), function (n) {
                scope.$watch(n, function () {
                    scope.validate();
                });
            });
        }
    };
}])

Example how to use it to make cross validated fields:

<input name="price1"
       ng-model="price1" 
       ensure-expression="price1 > price2" 
       ensure-watch="price2" />
<input name="price2" 
       ng-model="price2" 
       ensure-expression="price2 > price3" 
       ensure-watch="price3" />
<input name="price3" 
       ng-model="price3" 
       ensure-expression="price3 > price1 && price3 > price2" 
       ensure-watch="price1,price2" />

ensure-expression is executed to validate model when ng-model or any of ensure-watch variables is changed.

git cherry-pick : Apply the changes introduced by some existing commits

Assume we have branch A with (X, Y, Z) commits. We need to add these commits to branch B. We are going to use the cherry-pick operations.

When we use cherry-pick, we should add commits on branch B in the same chronological order that the commits appear in Branch A.

cherry-pick does support a range of commits, but if you have merge commits in that range, it gets really complicated

git checkout B
git cherry-pick SHA-COMMIT-X
git cherry-pick SHA-COMMIT-Y
git cherry-pick SHA-COMMIT-Z

Example of workflow :

We can use cherry-pick with options

-e or --edit : With this option, git cherry-pick will let you edit the commit message prior to committing.

-n or --no-commit : Usually the command automatically creates a sequence of commits. This flag applies the changes necessary to cherry-pick each named commit to your working tree and the index, without making any commit. In addition, when this option is used, your index does not have to match the HEAD commit. The cherry-pick is done against the beginning state of your index.

Here an interesting article concerning cherry-pick.

The above answers are incorrect in that most over-ride the 'is this connection HTTPS' test to allow serving the pages over http irrespective of connection security.

The secure answer using an error-page on an NGINX specific http 4xx error code to redirect the client to retry the same request to https. (as outlined here https://serverfault.com/questions/338700/redirect-http-mydomain-com12345-to-https-mydomain-com12345-in-nginx )

The OP should use:

server {
  listen        12345;
  server_name   php.myadmin.com;

  root         /var/www/php;

  ssl           on;

  # If they come here using HTTP, bounce them to the correct scheme
  error_page 497 https://$server_name:$server_port$request_uri;

  [....]
}

word-wrap: break-word;

worked for me.

Use this:

alert($(".messageCheckbox").is(":checked").val())

This assumes the checkboxes to check have the class "messageCheckbox", otherwise you would have to do a check if the input is the checkbox type, etc.

I had run into the similar problem recently, and managed to fix it with adding classes

  body .btn-primary {
    background-color: #7bc143;
    border-color: #7bc143;
    color: #FFF; }
    body .btn-primary:hover, body .btn-primary:focus {
      border-color: #6fb03a;
      background-color: #6fb03a;
      color: #FFF; }
    body .btn-primary:active, body .btn-primary:visited, body .btn-primary:active:focus, body .btn-primary:active:hover {
      border-color: #639d34;
      background-color: #639d34;
      color: #FFF; }

Also pay attention to [disabled] and [disabled]:hover, if this class is used on input[type=submit]. Like this:

body .btn-primary[disabled], body .btn-primary[disabled]:hover {
  background-color: #7bc143;
  border-color: #7bc143; }

function splitText(value, index) {
  if (value.length < index) {return value;} 
  return [value.substring(0, index)].concat(splitText(value.substring(index), index));
}
console.log(splitText('this is a testing peace of text',10));
// ["this is a ", "testing pe", "ace of tex", "t"] 

For those who want to split a text into array using the index.

Link to something more sensible than the top of the page in the first place. Then cancel the default event.

If I understand correctly, you have a vector containing variable names and would like loop through each name and sort your data frame by them. If so, this example should illustrate a solution for you. The primary issue in yours (the full example isn't complete so I"m not sure what else you may be missing) is that it should be order(Q1_R1000[,parameter[X]]) instead of order(Q1_R1000$parameter[X]), since parameter is an external object that contains a variable name opposed to a direct column of your data frame (which when the $ would be appropriate).

set.seed(1)
dat <- data.frame(var1=round(rnorm(10)),
                   var2=round(rnorm(10)),
                   var3=round(rnorm(10)))
param <- paste0("var",1:3)
dat
#   var1 var2 var3
#1    -1    2    1
#2     0    0    1
#3    -1   -1    0
#4     2   -2   -2
#5     0    1    1
#6    -1    0    0
#7     0    0    0
#8     1    1   -1
#9     1    1    0
#10    0    1    0

for(p in rev(param)){
   dat <- dat[order(dat[,p]),]
 }
dat
#   var1 var2 var3
#3    -1   -1    0
#6    -1    0    0
#1    -1    2    1
#7     0    0    0
#2     0    0    1
#10    0    1    0
#5     0    1    1
#8     1    1   -1
#9     1    1    0
#4     2   -2   -2

I believe you are trying to do exactly what I just tried to do: I want two stacked canvases... the bottom one has a static image and the top one contains animated sprites. Because of the animation, you need to clear the background of the top layer to transparent at the start of rendering every new frame. I finally found the answer: it's not using globalAlpha, and it's not using a rgba() color. The simple, effective answer is:

context.clearRect(0,0,width,height);

You can use the strdup function which has the following prototype

char *strdup(const char *s1);

Example of use:

#include <string.h>

char * my_str = strdup("My string literal!");
char * my_other_str = strdup(some_const_str);

or strcpy/strncpy to your buffer

or rewrite your functions to use const char * as parameter instead of char * where possible so you can preserve the const

A solution is available that allows me to keep my MacPorts installation by configuring the Ipython kernelspec.

Requirements:

• MacPorts is installed in the usual /opt directory
• python 2.7 is installed through macports
• python 3.4 is installed through macports
• Ipython is installed for python 2.7
• Ipython is installed for python 3.4

For python 2.x:

$ cd /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin
$ sudo ./ipython kernelspec install-self

For python 3.x:

$ cd /opt/local/Library/Frameworks/Python.framework/Versions/3.4/bin
$ sudo ./ipython kernelspec install-self

Now you can open an Ipython notebook and then choose a python 2.x or a python 3.x notebook.

If you only want the create tables, then you can do pg_dump -s databasename | awk 'RS="";/CREATE TABLE[^;]*;/'

To pipe the result to the response object (scenarios where there is a need to download the zip rather than store locally)

 archive.pipe(res);

Sam's hints for accessing the content of the directory worked for me.

src: ["**/*"]

While the answer above is correct I would not recommend you to change the name in order to rely on it in the code.

Names are tricky. They can change. You should use the ShapeId and SlideId.

Especially beware to change the name of a shape programmatically since PowerPoint relies on the name and it might hinder its regular operation.

I hadn't considered fillRect(), but the answers spurred me to benchmark it against putImage().

Putting 100,000 randomly coloured pixels in random locations, with Chrome 9.0.597.84 on an (old) MacBook Pro, takes less than 100ms with putImage(), but nearly 900ms using fillRect(). (Benchmark code at http://pastebin.com/4ijVKJcC).

If instead I choose a single colour outside of the loops and just plot that colour at random locations, putImage() takes 59ms vs 102ms for fillRect().

It seems that the overhead of generating and parsing a CSS colour specification in rgb(...) syntax is responsible for most of the difference.

Putting raw RGB values straight into an ImageData block on the other hand requires no string handling or parsing.

My solution:

Create a function script that is called earlier than all other functions without passing any arguments to it, like this:

! /bin/bash

function init(){ ORIGOPT= "- $@ -" }

Afer that, you can call init and use the ORIGOPT var as needed,as a plus, I always assign a new var and copy the contents of ORIGOPT in my new functions, that way you can keep yourself assured nobody is going to touch it or change it.

I added spaces and dashes to make it easier to parse it with 'sed -E' also bash will not pass it as reference and make ORIGOPT grow as functions are called with more arguments.

By lines I assume you mean rows in the table person. What you're looking for is:

select p.name
from   person p
where  p.name LIKE '%A%'; --contains the character 'A'

The above is case sensitive. For a case insensitive search, you can do:

select p.name
from   person p
where  UPPER(p.name) LIKE '%A%'; --contains the character 'A' or 'a'

For the special character, you can do:

select p.name
from   person p
where  p.name LIKE '%'||chr(8211)||'%'; --contains the character chr(8211)

The LIKE operator matches a pattern. The syntax of this command is described in detail in the Oracle documentation. You will mostly use the % sign as it means match zero or more characters.

>> "1,2,3,4".split(",")
=> ["1", "2", "3", "4"]

Or for integers:

>> "1,2,3,4".split(",").map { |s| s.to_i }
=> [1, 2, 3, 4]

Or for later versions of ruby (>= 1.9 - as pointed out by Alex):

>> "1,2,3,4".split(",").map(&:to_i)
=> [1, 2, 3, 4]

Tenary Operator helps keep it short and simple.

echo (isset($_SERVER['HTTPS']) ? 'http' : 'https' ). "://" . $_SERVER['SERVER_NAME']  ;

For completeness, on Apache2 on Ubuntu, you will find the default charset in charset.conf in conf-available.

Uncomment the line

AddDefaultCharset UTF-8

Just found this old thread, looking for some kind of escape sequence to blank the actual line.

It's quite funny no one came to the idea (or I have missed it) that printf returns the number of characters written. So just print '\r' + as many blank characters as printf returned and you will exactly blank the previuosly written text.

int BlankBytes(int Bytes)
{
                char strBlankStr[16];

                sprintf(strBlankStr, "\r%%%is\r", Bytes);
                printf(strBlankStr,"");

                return 0;
}

int main(void)
{
                int iBytesWritten;
                double lfSomeDouble = 150.0;

                iBytesWritten = printf("test text %lf", lfSomeDouble);

                BlankBytes(iBytesWritten);

                return 0;
}

As I cant use VT100, it seems I have to stick with that solution

2012 This is a better solution for this scenario (tested With Visual Studio 2008):

Configuration config = WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);
config.AppSettings.Settings.Remove("MyVariable");
config.AppSettings.Settings.Add("MyVariable", "MyValue");
config.Save();

Update 2018 =>
Tested in vs 2015 - Asp.net MVC5

var config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
config.AppSettings.Settings["MyVariable"].Value = "MyValue";
config.Save();

if u need to checking element exist, use this code:

var config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
if (config.AppSettings.Settings["MyVariable"] != null)
{
config.AppSettings.Settings["MyVariable"].Value = "MyValue";
}
else { config.AppSettings.Settings.Add("MyVariable", "MyValue"); }
config.Save();

.NET 4 and later only

Good news, everyone!

The perfect tool for this job is built in .NET 4 and it's called ConditionalWeakTable<TKey, TValue>. This class:

• can be used to associate arbitrary data with managed object instances much like a dictionary (although it is not a dictionary)
• does not depend on memory addresses, so is immune to the GC compacting the heap
• does not keep objects alive just because they have been entered as keys into the table, so it can be used without making every object in your process live forever
• uses reference equality to determine object identity; moveover, class authors cannot modify this behavior so it can be used consistently on objects of any type
• can be populated on the fly, so does not require that you inject code inside object constructors

Try this:

$(document).ready( function () {
  $('#example').dataTable({
    "order": []
  });
});

this will solve your problem.

I was getting this error even when all the relevant dependencies were in place because I hadn't created the schema in MySQL.

I thought it would be created automatically but it wasn't. Although the table itself will be created, you have to create the schema.

If you are using a data source, here's another way to do it without code behind.

Note the following key points:

• The ListItem of Value="0" is on the source page, not added in code
• The ListItem in the source will be overwritten if you don't include AppendDataBoundItems="true" in the DropDownList
• InitialValue="0" tells the validator that this is the value that should fire that validator (as pointed out in other answers)

Example:

<asp:DropDownList ID="ddlType" runat="server" DataSourceID="sdsType"
                  DataValueField="ID" DataTextField="Name" AppendDataBoundItems="true">
    <asp:ListItem Value="0" Text="--Please Select--" Selected="True"></asp:ListItem>
</asp:DropDownList>
<asp:RequiredFieldValidator ID="rfvType" runat="server" ControlToValidate="ddlType" 
                            InitialValue="0" ErrorMessage="Type required"></asp:RequiredFieldValidator>
<asp:SqlDataSource ID="sdsType" runat="server" 
                   ConnectionString='<%$ ConnectionStrings:TESTConnectionString %>'
                   SelectCommand="SELECT ID, Name FROM Type"></asp:SqlDataSource>

One thing I find easy to do is i set an array of empty strings for the size I prefer, for example

Code:

import numpy as np

x= np.zeros(5,str)
print x

Output:

['' '' '' '' '']

Hope this is helpful :)

Is there a reason you didn't just use this?

<select id="animal" name="animal">                      
  <option value="0">--Select Animal--</option>
  <option value="Cat">Cat</option>
  <option value="Dog">Dog</option>
  <option value="Cow">Cow</option>
</select>

if($_POST['submit'] && $_POST['submit'] != 0)
{
   $animal=$_POST['animal'];
}

The following can be called with any range as parameter:

Option Explicit

Sub SetRangeBorder(poRng As Range)
    If Not poRng Is Nothing Then
        poRng.Borders(xlDiagonalDown).LineStyle = xlNone
        poRng.Borders(xlDiagonalUp).LineStyle = xlNone
        poRng.Borders(xlEdgeLeft).LineStyle = xlContinuous
        poRng.Borders(xlEdgeTop).LineStyle = xlContinuous
        poRng.Borders(xlEdgeBottom).LineStyle = xlContinuous
        poRng.Borders(xlEdgeRight).LineStyle = xlContinuous
        poRng.Borders(xlInsideVertical).LineStyle = xlContinuous
        poRng.Borders(xlInsideHorizontal).LineStyle = xlContinuous
    End If
End Sub

Examples:

Call SetRangeBorder(Range("C11"))
Call SetRangeBorder(Range("A" & result))
Call SetRangeBorder(DT.Cells(I, 6))
Call SetRangeBorder(Range("A3:I" & endRow))

Your code should look like below

let image = UIImage(named: "name") as UIImage?
let button   = UIButton(type: UIButtonType.Custom) as UIButton
button.frame = CGRectMake(100, 100, 100, 100)
button.setImage(image, forState: .Normal)
button.addTarget(self, action: "btnTouched:", forControlEvents:.TouchUpInside)
self.view.addSubview(button)

As others answered you, if you are creating a new project, you can separate frontend and backend and use any django rest plugin to create rest api for your frontend application. This is in the ideal world.

If you have a project with the django templating already in place, then you must load your react dom render in the page you want to load the application. In my case I had already django-pipeline and I just added the browserify extension. (https://github.com/j0hnsmith/django-pipeline-browserify)

As in the example, I loaded the app using django-pipeline:

PIPELINE = {
    # ...
    'javascript':{
        'browserify': {
            'source_filenames' : (
                'js/entry-point.browserify.js',
            ),
            'output_filename': 'js/entry-point.js',
        },
    }
}

Your "entry-point.browserify.js" can be an ES6 file that loads your react app in the template:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './components/app.js';
import "babel-polyfill";

import { Provider } from 'react-redux';
import { createStore, applyMiddleware } from 'redux';
import promise from 'redux-promise';
import reducers from './reducers/index.js';

const createStoreWithMiddleware = applyMiddleware(
  promise
)(createStore);

ReactDOM.render(
  <Provider store={createStoreWithMiddleware(reducers)}>
    <App/>
  </Provider>
  , document.getElementById('my-react-app')
);

In your django template, you can now load your app easily:

{% load pipeline %}

{% comment %} 
`browserify` is a PIPELINE key setup in the settings for django 
 pipeline. See the example above
{% endcomment %}

{% javascript 'browserify' %}

{% comment %} 
the app will be loaded here thanks to the entry point you created 
in PIPELINE settings. The key is the `entry-point.browserify.js` 
responsable to inject with ReactDOM.render() you react app in the div 
below
{% endcomment %}
<div id="my-react-app"></div>

The advantage of using django-pipeline is that statics get processed during the collectstatic.

There was same problem in my Colleague's code. This sounds as your Radio Group is not properly set with your Radio Buttons. This is the reason you can multi-select the radio buttons. I tried many things, finally i did a trick which is wrong actually, but works fine.

for ( int i = 0 ; i < myCount ; i++ )
{
    if ( i != k )
    {
        System.out.println ( "i = " + i );
        radio1[i].setChecked(false);
    }
}

Here I set one for loop, which checks for the available radio buttons and de-selects every one except the new clicked one. try it.

Try this

void Function()
{
    while (condition) 
    {
        await Task.Delay(1);
    }
}

This will make the program wait until the condition is not true. You can just invert it by adding a "!" infront of the condition so that it will wait until the condition is true.

No, you can't control the animation of the images.

You would need two versions of each image, one that is animated, and one that's not. On hover you can easily change from one image to another.

Example:

$(function(){
  $('img').each(function(e){
    var src = $(e).attr('src');
    $(e).hover(function(){
      $(this).attr('src', src.replace('.gif', '_anim.gif'));
    }, function(){
      $(this).attr('src', src);
    });
  });
});

Update:

Time goes by, and possibilities change. As kritzikatzi pointed out, having two versions of the image is not the only option, you can apparently use a canvas element to create a copy of the first frame of the animation. Note that this doesn't work in all browsers, IE 8 for example doesn't support the canvas element.

Actually, it is possible to provide the service (or guard, since that also needs to be provided) when creating the service.

The command is the following...

ng g s services/backendApi --module=app.module

Edit

It is possible to provide to a feature module, as well, you must give it the path to the module you would like.

ng g s services/backendApi --module=services/services.module

git 2.7.1 (February 2016) clarifies that in commit b2c150d (05 Jan 2016) by David A. Wheeler (david-a-wheeler).
^{(Merged by Junio C Hamano -- gitster -- in commit 7aae9ba, 05 Feb 2016)}

git commit man page now includes:

-s::
--signoff::

Add Signed-off-by line by the committer at the end of the commit log message.
The meaning of a signoff depends on the project, but it typically certifies that committer has the rights to submit this work under the same license and agrees to a Developer Certificate of Origin (see https://developercertificate.org for more information).

Expand documentation describing --signoff

Modify various document (man page) files to explain in more detail what --signoff means.

This was inspired by "lwn article 'Bottomley: A modest proposal on the DCO'" (Developer Certificate of Origin) where paulj noted:

The issue I have with DCO is that there adding a "-s" argument to git commit doesn't really mean you have even heard of the DCO (the git commit man page makes no mention of the DCO anywhere), never mind actually seen it.

So how can the presence of "signed-off-by" in any way imply the sender is agreeing to and committing to the DCO? Combined with fact I've seen replies on lists to patches without SOBs that say nothing more than "Resend this with signed-off-by so I can commit it".

Extending git's documentation will make it easier to argue that developers understood --signoff when they use it.

Note that this signoff is now (for Git 2.15.x/2.16, Q1 2018) available for git pull as well.

See commit 3a4d2c7 (12 Oct 2017) by W. Trevor King (wking).
^{(Merged by Junio C Hamano -- gitster -- in commit fb4cd88, 06 Nov 2017)}

pull: pass --signoff/--no-signoff to "git merge"

merge can take --signoff, but without pull passing --signoff down, it is inconvenient to use; allow 'pull' to take the option and pass it through.

I've read that using document fragments is performant because it avoids page reflow upon each insertion of DOM element, it's also well supported by all browsers (even IE 6).

var fragment = document.createDocumentFragment();_x000D_
_x000D_
$.each(result, function() {_x000D_
  fragment.appendChild($("<option />").val(this.ImageFolderID).text(this.Name)[0]);_x000D_
});_x000D_
_x000D_
$("#options").append(fragment);

I first read about this in CodeSchool's JavaScript Best Practices course.

Here's a comparison of different approaches, thanks go to the author.

You were close. The key is to have the hidden layout inflate to match_parent in both height and weight. Simply start it off as View.GONE. This way, using the percentage in the animators works properly.

Layout (activity_main.xml):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/main_screen"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="@string/hello_world" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="@string/hello_world" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:onClick="slideUpDown"
        android:text="Slide up / down" />

    <RelativeLayout
        android:id="@+id/hidden_panel"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/white"
        android:visibility="gone" >

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/app_name"
            android:layout_centerInParent="true"
            android:onClick="slideUpDown" />
    </RelativeLayout>

</RelativeLayout>

Activity (MainActivity.java):

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;

public class OffscreenActivity extends Activity {
    private View hiddenPanel;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_activity);

        hiddenPanel = findViewById(R.id.hidden_panel);
    }

    public void slideUpDown(final View view) {
        if (!isPanelShown()) {
            // Show the panel
            Animation bottomUp = AnimationUtils.loadAnimation(this,
                    R.anim.bottom_up);

            hiddenPanel.startAnimation(bottomUp);
            hiddenPanel.setVisibility(View.VISIBLE);
        }
        else {
            // Hide the Panel
            Animation bottomDown = AnimationUtils.loadAnimation(this,
                    R.anim.bottom_down);

            hiddenPanel.startAnimation(bottomDown);
            hiddenPanel.setVisibility(View.GONE);
        }
    }

    private boolean isPanelShown() {
        return hiddenPanel.getVisibility() == View.VISIBLE;
    }

}

Only other thing I changed was in bottom_up.xml. Instead of

android:fromYDelta="75%p"

I used:

android:fromYDelta="100%p"

But that's a matter of preference, I suppose.

The canonical solution is the one mentioned by another respondent:

sort | uniq -c

It is shorter and more concise than what can be written in Perl or awk.

You write that you don't want to use sort, because the data's size is larger than the machine's main memory size. Don't underestimate the implementation quality of the Unix sort command. Sort was used to handle very large volumes of data (think the original AT&T's billing data) on machines with 128k (that's 131,072 bytes) of memory (PDP-11). When sort encounters more data than a preset limit (often tuned close to the size of the machine's main memory) it sorts the data it has read in main memory and writes it into a temporary file. It then repeats the action with the next chunks of data. Finally, it performs a merge sort on those intermediate files. This allows sort to work on data many times larger than the machine's main memory.

Excerpted from Josh Stodola's Setting keyboard caret Position in a Textbox or TextArea with Javascript

A generic function that will allow you to insert the caret at any position of a textbox or textarea that you wish:

function setCaretPosition(elemId, caretPos) {
    var elem = document.getElementById(elemId);

    if(elem != null) {
        if(elem.createTextRange) {
            var range = elem.createTextRange();
            range.move('character', caretPos);
            range.select();
        }
        else {
            if(elem.selectionStart) {
                elem.focus();
                elem.setSelectionRange(caretPos, caretPos);
            }
            else
                elem.focus();
        }
    }
}

The first expected parameter is the ID of the element you wish to insert the keyboard caret on. If the element is unable to be found, nothing will happen (obviously). The second parameter is the caret positon index. Zero will put the keyboard caret at the beginning. If you pass a number larger than the number of characters in the elements value, it will put the keyboard caret at the end.

Tested on IE6 and up, Firefox 2, Opera 8, Netscape 9, SeaMonkey, and Safari. Unfortunately on Safari it does not work in combination with the onfocus event).

An example of using the above function to force the keyboard caret to jump to the end of all textareas on the page when they receive focus:

function addLoadEvent(func) {
    if(typeof window.onload != 'function') {
        window.onload = func;
    }
    else {
        if(func) {
            var oldLoad = window.onload;

            window.onload = function() {
                if(oldLoad)
                        oldLoad();

                func();
            }
        }
    }
}

// The setCaretPosition function belongs right here!

function setTextAreasOnFocus() {
/***
 * This function will force the keyboard caret to be positioned
 * at the end of all textareas when they receive focus.
 */
    var textAreas = document.getElementsByTagName('textarea');

    for(var i = 0; i < textAreas.length; i++) {
        textAreas[i].onfocus = function() {
            setCaretPosition(this.id, this.value.length);
        }
    }

    textAreas = null;
}

addLoadEvent(setTextAreasOnFocus);

', '.join(set_3)

The join is a string method, not a set method.

There's no history in the database itself,but if you are using DataGrip data management tool then you can check the history thats your run in the datagrip.

Here is from me to share

Option 1 - counting from same domain from different table

select distinct(select count(*) from domain1.table1) "count1", (select count(*) from domain1.table2) "count2" 
from domain1.table1, domain1.table2;

Option 2 - counting from different domain for same table

select distinct(select count(*) from domain1.table1) "count1", (select count(*) from domain2.table1) "count2" 
from domain1.table1, domain2.table1;

Option 3 - counting from different domain for same table with "union all" to have rows of count

select 'domain 1'"domain", count(*) 
from domain1.table1 
union all 
select 'domain 2', count(*) 
from domain2.table1;

Enjoy the SQL, I always do :)

Try using

<pre style="white-space:normal;">. 

Or better throw CSS.

SELECT * 
FROM people 
WHERE names ='SMITH'
ORDER BY names asc
limit 10

If you need add group by clause. If you search Smith you would have to sort on something else.

I am the original poster and I accepted the above answer by DGH without having first used it in the code.

Once I did use I realised that it needed a little tweaking to actually do what I needed it to do (to be fair to DGH he/she did say "or something similar" !).

I thought it was worth posting the tweak here for the benefit of others:

    try:
        a = Application("abcdef", "")
    except pySourceAidExceptions.PathIsNotAValidOne:
        pass
    except:
        self.assertTrue(False)

What I was attempting to do here was to ensure that if an attempt was made to instantiate an Application object with a second argument of spaces the pySourceAidExceptions.PathIsNotAValidOne would be raised.

I believe that using the above code (based heavily on DGH's answer) will do that.

Finally tracked this down with the help of WinDBG and SOS. Access violation was being thrown by some unknown DLL. Turns out a piece of software called "Nvidia Network Manager" was causing the problems. I'd read countless times how this issue can be caused by firewalls or antivirus, neither of which I am using so I dismissed this idea. Also, I was under the assumption that it was not environmental because it occurs on more than 1 server using different hardware. Turns out all the machines I tested this on were running "NVidia Network Manager". I believe it installs with the rest of the motherboard drivers.

Hopefully this helps someone as this issue was plaguing my application for a very long time.

The ideal is 1 thread per core, as long as none of the threads will block.

One case where this may not be true: there are other threads running on the core, in which case more threads may give your program a bigger slice of the execution time.

Set objHTTP = CreateObject("MSXML2.ServerXMLHTTP")
URL = "http://www.somedomain.com"
objHTTP.Open "POST", URL, False
objHTTP.setRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
objHTTP.send("")

Alternatively, for greater control over the HTTP request you can use WinHttp.WinHttpRequest.5.1 in place of MSXML2.ServerXMLHTTP.

One other option is to use a plyr function:

df <- ldply(listOfDataFrames, data.frame)

This is a little slower than the original:

> system.time({ df <- do.call("rbind", listOfDataFrames) })
   user  system elapsed 
   0.25    0.00    0.25 
> system.time({ df2 <- ldply(listOfDataFrames, data.frame) })
   user  system elapsed 
   0.30    0.00    0.29
> identical(df, df2)
[1] TRUE

My guess is that using do.call("rbind", ...) is going to be the fastest approach that you will find unless you can do something like (a) use a matrices instead of a data.frames and (b) preallocate the final matrix and assign to it rather than growing it.

Edit 1:

Based on Hadley's comment, here's the latest version of rbind.fill from CRAN:

> system.time({ df3 <- rbind.fill(listOfDataFrames) })
   user  system elapsed 
   0.24    0.00    0.23 
> identical(df, df3)
[1] TRUE

This is easier than rbind, and marginally faster (these timings hold up over multiple runs). And as far as I understand it, the version of plyr on github is even faster than this.

I hide the warnings in the pink boxes by running the following code in a cell:

from IPython.display import HTML
HTML('''<script>
code_show_err=false; 
function code_toggle_err() {
 if (code_show_err){
 $('div.output_stderr').hide();
 } else {
 $('div.output_stderr').show();
 }
 code_show_err = !code_show_err
} 
$( document ).ready(code_toggle_err);
</script>
To toggle on/off output_stderr, click <a href="javascript:code_toggle_err()">here</a>.''')

From my iphone I wanted to browse a website hosted on IIS server on my Windows 8 laptop. After some reading around, I opened Windows Firewall, selected "Allow an app or feature through Windows firewall". Then scrolled down and checked "World Wide Web Services (HTTP)" from the list. That's all, it worked. Hope it helps someone else too.

Using eq() you can target the third cell in the table:

$('#table_header td').eq(2).html('new content');

If you wanted to target every third cell in each row, use the nth-child-selector:

$('#table_header td:nth-child(3)').html('new content');

ou can use String.compareTo(String) that returns an integer that's negative (<), zero(=) or positive(>).

Use it so:

You can use String.compareTo(String) that returns an integer that's negative (<), zero(=) or positive(>).

Use it so:

  String a="myWord";
  if(a.compareTo(another_string) <0){
    //a is strictly < to another_string
  }
  else if (a.compareTo(another_string) == 0){
    //a equals to another_string
  }
else{
  // a is strictly > than another_string

CSS transitions only animate from one set of styles to another; what you're looking for is CSS animations.

You need to define the animation keyframes and apply it to the element:

@keyframes changewidth {
  from {
    width: 100px;
  }

  to {
    width: 300px;
  }
}

div {
  animation-duration: 0.1s;
  animation-name: changewidth;
  animation-iteration-count: infinite;
  animation-direction: alternate;
}

Check out the link above to figure out how to customize it to your liking, and you'll have to add browser prefixes.

Open Anaconda cmd in base mode:

Then use conda update conda to update Anaconda.

You can then use conda update --all to update all the requirements for Anaconda:

conda update conda
conda update --all

mvn install is the option that is most often used.
mvn package is seldom used, only if you're debugging some issue with the maven build process.

See: http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html

Note that mvn package will only create a jar file.
mvn install will do that and install the jar (and class etc.) files in the proper places if other code depends on those jars.

I usually do a mvn clean install; this deletes the target directory and recreates all jars in that location.
The clean helps with unneeded or removed stuff that can sometimes get in the way.
Rather then debug (some of the time) just start fresh all of the time.

You can use .map: http://jsfiddle.net/9ndcL/1/.

// array of text of each td

var texts = $("td").map(function() {
    return $(this).text();
});

If you want to build Java EE applications, it's best to use Eclipse IDE for Java EE. It has editors from HTML to JSP/JSF, Javascript. It's rich for webapps development, and provide plugins and tools to develop Java EE applications easily (all bundled).

Eclipse Classic is basically the full featured Eclipse without the Java EE part.

The accepted answer didn't work for me in Android 2.2. I don't know why, but it was "eating" some of my zeros (0) . Apache commons also didn't work on Android 2.2, because it uses methods that are supported only starting from Android 2.3.x. Also, if you want to just MD5 a string, Apache commons is too complex for that. Why one should keep a whole library to use just a small function from it...

Finally I found the following code snippet here which worked perfectly for me. I hope it will be useful for someone...

public String MD5(String md5) {
   try {
        java.security.MessageDigest md = java.security.MessageDigest.getInstance("MD5");
        byte[] array = md.digest(md5.getBytes("UTF-8"));
        StringBuffer sb = new StringBuffer();
        for (int i = 0; i < array.length; ++i) {
          sb.append(Integer.toHexString((array[i] & 0xFF) | 0x100).substring(1,3));
       }
        return sb.toString();
    } catch (java.security.NoSuchAlgorithmException e) {
    } catch(UnsupportedEncodingException ex){
    }
    return null;
}

It's easy to make a message, here's how:

First open notpad and type:

msg "Message",0,"Title"

and save it as Message.vbs.

Now in your batch file type:

Message.vbs %*

I had the same problem on MacOS 10.10. And I found that the problem caused by OhMyZsh shell. Then I switched back to bash everything went ok.

The Chapter object should have reference to the book it came from so I would suggest something like chapter.getBook().getTitle();

Your database table structure should have a books table and a chapters table with columns like:

books

• id
• book specific info
• etc

chapters

• id
• book_id
• chapter specific info
• etc

Then to reduce the number of queries use a join table in your search query.

I usually do this by creating a htc file (ex. last-child.htc):

<attach event="ondocumentready" handler="initializeBehaviours" />
<script type="text/javascript">
function initializeBehaviours() {
  this.lastChild.className += ' last-child';
}
</script>

And call it from my IE conditional css file with:

ul { behavior: url("/javascripts/htc/last-child.htc"); }

Whereas in my main css file I got:

ul li:last-child,
ul li.last-child {
  /* some code */
}

Another solution (albeit slower) that uses your existent css markup without defining any .last-child class would be Dean Edwards ie7.js library.

You have no need to put for loop to see the data into the array, you can simply do in following manner

<?php
echo "<pre>";
 print_r($results); 
echo "</pre>";
?>

Try use Build Timestamp Plugin and use BUILD_TIMESTAMP variable.

I don't know if this question is still relevant, but there is such possibility in Postman now. They added it a few months ago.

All you need is create simple .js file and run it via node.js. It looks like this:

var path = require('path'),
  async = require('async'), //https://www.npmjs.com/package/async
  newman = require('newman'),

  parametersForTestRun = {
    collection: path.join(__dirname, 'postman_collection.json'), // your collection
    environment: path.join(__dirname, 'postman_environment.json'), //your env
  };

parallelCollectionRun = function(done) {
  newman.run(parametersForTestRun, done);
};

// Runs the Postman sample collection thrice, in parallel.
async.parallel([
    parallelCollectionRun,
    parallelCollectionRun,
    parallelCollectionRun
  ],
  function(err, results) {
    err && console.error(err);

    results.forEach(function(result) {
      var failures = result.run.failures;
      console.info(failures.length ? JSON.stringify(failures.failures, null, 2) :
        `${result.collection.name} ran successfully.`);
    });
  });

Then just run this .js file ('node fileName.js' in cmd).

s.append("a");
// System.out.print(s); is return "aa"
s.delete(0, s.length());
System.out.print(s.length()); // is return 0

is the easy way.

This will do it recursively for you:

find /path/to/base/dir/* -type d -ctime +10 -exec rm -rf {} \;

Explanation:

• find: the unix command for finding files / directories / links etc.
• /path/to/base/dir: the directory to start your search in.
• -type d: only find directories
• -ctime +10: only consider the ones with modification time older than 10 days
• -exec ... \;: for each such result found, do the following command in ...
• rm -rf {}: recursively force remove the directory; the {} part is where the find result gets substituted into from the previous part.

Alternatively, use:

find /path/to/base/dir/* -type d -ctime +10 | xargs rm -rf

Which is a bit more efficient, because it amounts to:

rm -rf dir1 dir2 dir3 ...

as opposed to:

rm -rf dir1; rm -rf dir2; rm -rf dir3; ...

as in the -exec method.

With modern versions of find, you can replace the ; with + and it will do the equivalent of the xargs call for you, passing as many files as will fit on each exec system call:

find . -type d -ctime +10 -exec rm -rf {} +

The only solution I have found is not to set the index to a previous frame and wait (then OpenCV stops reading frames, anyway), but to initialize the capture one more time. So, it looks like this:

cap = cv2.VideoCapture(camera_url)
while True:
    ret, frame = cap.read()

    if not ret:
        cap = cv.VideoCapture(camera_url)
        continue

    # do your processing here

And it works perfectly!

Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.

If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like

double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);

(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)

If you are running a really old version of nltk, then there is indeed no download module available (reference)

Try this:

import nltk
print(nltk.__version__)

As per the reference, anything after 0.9.5 should be fine

You can also try

System.Environment.GetEnvironmentVariable("UserName");

The problem was a missing dependency that wasn't on the server but was on my local machine. In our case, it was a Devart.Data.Linq dll.

To get to that answer, I turned on IIS tracing for 500 errors. That gave a little bit of information, but the really helpful thing was in the web.config setting the <system.web><customErrors mode="Off"/></system.web> This pointed to a missing dynamically-loaded dependency. After adding this dependency and telling it to be copied locally, the server started working.

In testing2.php use the following code to get the name:

if ( ! empty($_POST['name'])){
    $name = $_POST['name']);
}

When you create the next page, use the value of $name to prefill the form field:

Name: <input type="text" name="name" id="name" value="<?php echo $name; ?>"><br/>

However, before doing that, be sure to use regular expressions to verify that the $name only contains valid characters, such as:

$pattern =  '/^[0-9A-Za-zÁ-Úá-úàÀÜü]+$/';//integers & letters
if (preg_match($pattern, $name) == 1){
    //continue
} else {
    //reload form with error message
}

In C, the compiler is allowed to dictate some alignment for every primitive type. Typically the alignment is the size of the type. But it's entirely implementation-specific.

Padding bytes are introduced so every object is properly aligned. Reordering is not allowed.

Possibly every remotely modern compiler implements #pragma pack which allows control over padding and leaves it to the programmer to comply with the ABI. (It is strictly nonstandard, though.)

From C99 §6.7.2.1:

12 Each non-bit-field member of a structure or union object is aligned in an implementation- defined manner appropriate to its type.

13 Within a structure object, the non-bit-field members and the units in which bit-fields reside have addresses that increase in the order in which they are declared. A pointer to a structure object, suitably converted, points to its initial member (or if that member is a bit-field, then to the unit in which it resides), and vice versa. There may be unnamed padding within a structure object, but not at its beginning.

As you see, the solution is what everyone has already mentioned - simply by Suspending ReSharper, then Clearing the Caches, and finally Resuming it. But, no one mentioned how to do it without closing/restarting Visual Studio.

Just follow these steps:

1. Getting ReSharper Cache Location

   • Manually by going to ReSharper Options > Environment > General > Store Solution Caches in (Combo Box) (marked 2 in the image). Selecting Custom Folder, then Copying the location of the Caches Folder from the text box shown (marked 3 in the image). Reverting the settings back. The 1 marked shows the ClearCache Button. It's usually wouldn't work so leave it.

2. Suspending ReSharper

   • You can do this by going to Tools > Options > ReSharper Or ReSharper Ultimate > Suspend Now (Button)

3. Clearing the Cache

   • Go to the location copied earlier in step 1 and delete everything in that folder. And yes, I do mean everything.

4. Resuming ReSharper

   • You can do this by again going to Tools > Options > ReSharper Or ReSharper Ultimate > Resume (Button)

in Bootstrap Table 4.x

If you are creating the table in the init parameters instead of using HTML.

You can specify the width parameters in the columns attribute:

$("table").bootstrapTable({
    columns: [
        { field: "title", title: "title", width: "100px" }
    ]
});

The fix

Go to Project Structure - Modules - Source Folders and find the target/generated-sources/antlr4/com/mycompany - click Edit properties and set Package prefix to com.mycompany.

This is exactly the reason why we can set Package prefix on source dirs.

If you really want to insert this record, remove the `abuse_id` field and the corresponding value from the INSERTstatement :

INSERT INTO  `abuses` (  `user_id` ,  `abuser_username` ,  `comment` ,  `reg_date` , `auction_id` ) 
VALUES ( 100020,  'artictundra', 'I placed a bid for it more than an hour ago. It is still active. I thought I was supposed to get an email after 15 minutes.', 1338052850, 108625 ) ;

Try this

frame$twohouses <- ifelse(frame$data>1, 2, 1)
 frame
   data twohouses
1     0         1
2     1         1
3     2         2
4     3         2
5     4         2
6     2         2
7     3         2
8     1         1
9     4         2
10    3         2

15    2         2
16    0         1
17    2         2
18    1         1
19    2         2
20    0         1
21    4         2

Try:

bash -c '[ -d my_mystery_dirname ] && run_this_command'

This will work if you can run bash on the remote machine....

In bash, [ -d something ] checks if there is directory called 'something', returning a success code if it exists and is a directory. Chaining commands with && runs the second command only if the first one succeeded. So [ -d somedir ] && command runs the command only if the directory exists.

All above answers compares well, but if you need to use custom function for mapping, and you have numpy.ndarray, and you need to retain the shape of array.

I have compare just two, but it will retain the shape of ndarray. I have used the array with 1 million entries for comparison. Here I use square function. I am presenting the general case for n dimensional array. For two dimensional just make iter for 2D.

import numpy, time

def A(e):
    return e * e

def timeit():
    y = numpy.arange(1000000)
    now = time.time()
    numpy.array([A(x) for x in y.reshape(-1)]).reshape(y.shape)        
    print(time.time() - now)
    now = time.time()
    numpy.fromiter((A(x) for x in y.reshape(-1)), y.dtype).reshape(y.shape)
    print(time.time() - now)
    now = time.time()
    numpy.square(y)  
    print(time.time() - now)

Output

>>> timeit()
1.162431240081787    # list comprehension and then building numpy array
1.0775556564331055   # from numpy.fromiter
0.002948284149169922 # using inbuilt function

here you can clearly see numpy.fromiter user square function, use any of your choice. If you function is dependent on i, j that is indices of array, iterate on size of array like for ind in range(arr.size), use numpy.unravel_index to get i, j, .. based on your 1D index and shape of array numpy.unravel_index

With VisualStudio 2012 there is a way to handle subj without publish profiles. You can pass output folder using parameters. It works both with absolute and relative path in 'publishUrl' parameter. You can use VS100COMNTOOLS, however you need to override VisualStudioVersion to use target 'WebPublish' from %ProgramFiles%\MSBuild\Microsoft\VisualStudio\v11.0\WebApplications\Microsoft.WebApplication.targets. With VisualStudioVersion 10.0 this script will succeed with no outputs :)

Update: I've managed to use this method on a build server with just Windows SDK 7.1 installed (no Visual Studio 2010 and 2012 on a machine). But I had to follow these steps to make it work:

1. Make Windows SDK 7.1 current on a machine using Simmo answer (https://stackoverflow.com/a/2907056/2164198)
2. Setting Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\SxS\VS7\10.0 to "C:\Program Files\Microsoft Visual Studio 10.0\" (use your path as appropriate)
3. Copying folder %ProgramFiles%\MSBuild\Microsoft\VisualStudio\v11.0 from my developer machine to build server

Script:

set WORK_DIR=%~dp0
pushd %WORK_DIR%
set OUTPUTS=%WORK_DIR%..\Outputs
set CONFIG=%~1
if "%CONFIG%"=="" set CONFIG=Release
set VSTOOLS="%VS100COMNTOOLS%"
if %VSTOOLS%=="" set "PATH=%PATH%;%WINDIR%\Microsoft.NET\Framework\v4.0.30319" && goto skipvsinit
call "%VSTOOLS:~1,-1%vsvars32.bat"
if errorlevel 1 goto end
:skipvsinit
msbuild.exe Project.csproj /t:WebPublish /p:Configuration=%CONFIG% /p:VisualStudioVersion=11.0 /p:WebPublishMethod=FileSystem /p:publishUrl=%OUTPUTS%\Project
if errorlevel 1 goto end
:end
popd
exit /b %ERRORLEVEL%

Somewhat of an old thread but, this seems to be a faster method using the latest version of matplotlib:

set the major formatter for the x-axis

ax.xaxis.set_major_formatter(plt.NullFormatter())

The documentation for focusout says (emphasis mine):

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

The same distinction exists between the focusin and focus events.

I have had the same problem. I had more than one Xcode window open, closing all other open windows leaving only the current one open solved the problem for me.

It is reasonable to make constructor private if there are other methods that can produce instances. Obvious examples are patterns Singleton (every call return the same instance) and Factory (every call usually create new instance).

Another way to handle this is to convert the date to unixtime (epoch), then add the equivalent in (milli)seconds, then convert it back. This way you can handle day and month transitions, like adding 4 hours to 21, which should result in the next day, 01:00.

In DOS you couldn't use environment variables on the command line, only in batch files, where they used the % sign as a delimiter. If you wanted a literal % sign in a batch file, e.g. in an echo statement, you needed to double it.

This carried over to Windows NT which allowed environment variables on the command line, however for backwards compatibility you still need to double your % signs in a .cmd file.

Try this, it worked for me.

<td><a href="Docs/Chapter 1_ORG.pdf" target="pdf-frame">Chapter-1 Organizational</a></td>

I realize this may be a bit late, but I stumbled upon this and was wondering how to handle situations with multiple identical values, but different keys (as per bigbearzhu's comment).

So I modified Stephan Muller's answer slightly:

A datalist with non-unique values:

<input list="answers" name="answer" id="answerInput">
<datalist id="answers">
  <option value="42">The answer</option>
  <option value="43">The answer</option>
  <option value="44">Another Answer</option>
</datalist>
<input type="hidden" name="answer" id="answerInput-hidden">

When the user selects an option, the browser replaces input.value with the value of the datalist option instead of the innerText.

The following code then checks for an option with that value, pushes that into the hidden field and replaces the input.value with the innerText.

document.querySelector('#answerInput').addEventListener('input', function(e) {
    var input = e.target,   
        list = input.getAttribute('list'),
        options = document.querySelectorAll('#' + list + ' option[value="'+input.value+'"]'),
        hiddenInput = document.getElementById(input.getAttribute('id') + '-hidden');

    if (options.length > 0) {
      hiddenInput.value = input.value;
      input.value = options[0].innerText;
      }

});

As a consequence the user sees whatever the option's innerText says, but the unique id from option.value is available upon form submit. Demo jsFiddle

Assuming your ints are 0, 375, 668,5 and 6:

{
    "Id": "610",
    "Name": "15",
    "Description": "1.99",
    "ItemModList": [
                       0,
                       375,
                       668,
                       5,
                       6
                   ]
}

I suggest that you change "Id": "610" to "Id": 610 since it is a integer/long and not a string. You can read more about the JSON format and examples here http://json.org/

Another option:

return new NotModified();

public class NotModified : IHttpActionResult
{
    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        var response = new HttpResponseMessage(HttpStatusCode.NotModified);
        return Task.FromResult(response);
    }
}

infowindow.open(null,null);

will close opened infowindow. It will work same as

First Install Vue Cli Globally

npm install -g @vue/cli

To create a new project, run:

vue create project-name

run vue

npm run serve 

Vue CLI >= 3 uses the same vue binary, so it overwrites Vue CLI 2 (vue-cli). If you still need the legacy vue init functionality, you can install a global bridge:

Vue Init Globally

npm install -g @vue/cli-init

vue init now works exactly the same as [email protected]

Vue Create App

vue init webpack my-project

Run developer server

npm run dev

Go into your directory and click on 'Settings' next to the little cog. There is a field to rename your directory.

Here is a demo code where there is pagination + Filtering with AngularJS :

https://codepen.io/lamjaguar/pen/yOrVym

JS :

var app=angular.module('myApp', []);

// alternate - https://github.com/michaelbromley/angularUtils/tree/master/src/directives/pagination
// alternate - http://fdietz.github.io/recipes-with-angular-js/common-user-interface-patterns/paginating-through-client-side-data.html

app.controller('MyCtrl', ['$scope', '$filter', function ($scope, $filter) {
    $scope.currentPage = 0;
    $scope.pageSize = 10;
    $scope.data = [];
    $scope.q = '';

    $scope.getData = function () {
      // needed for the pagination calc
      // https://docs.angularjs.org/api/ng/filter/filter
      return $filter('filter')($scope.data, $scope.q)
     /* 
       // manual filter
       // if u used this, remove the filter from html, remove above line and replace data with getData()

        var arr = [];
        if($scope.q == '') {
            arr = $scope.data;
        } else {
            for(var ea in $scope.data) {
                if($scope.data[ea].indexOf($scope.q) > -1) {
                    arr.push( $scope.data[ea] );
                }
            }
        }
        return arr;
       */
    }

    $scope.numberOfPages=function(){
        return Math.ceil($scope.getData().length/$scope.pageSize);                
    }

    for (var i=0; i<65; i++) {
        $scope.data.push("Item "+i);
    }
  // A watch to bring us back to the 
  // first pagination after each 
  // filtering
$scope.$watch('q', function(newValue,oldValue){             if(oldValue!=newValue){
      $scope.currentPage = 0;
  }
},true);
}]);

//We already have a limitTo filter built-in to angular,
//let's make a startFrom filter
app.filter('startFrom', function() {
    return function(input, start) {
        start = +start; //parse to int
        return input.slice(start);
    }
});

HTML :

<div ng-app="myApp" ng-controller="MyCtrl">
  <input ng-model="q" id="search" class="form-control" placeholder="Filter text">
  <select ng-model="pageSize" id="pageSize" class="form-control">
        <option value="5">5</option>
        <option value="10">10</option>
        <option value="15">15</option>
        <option value="20">20</option>
     </select>
  <ul>
    <li ng-repeat="item in data | filter:q | startFrom:currentPage*pageSize | limitTo:pageSize">
      {{item}}
    </li>
  </ul>
  <button ng-disabled="currentPage == 0" ng-click="currentPage=currentPage-1">
        Previous
    </button> {{currentPage+1}}/{{numberOfPages()}}
  <button ng-disabled="currentPage >= getData().length/pageSize - 1" ng-click="currentPage=currentPage+1">
        Next
    </button>
</div>

If you only need your CSS to be applied to one specific view, I'm using this handy snippet inside my controller:

$("body").addClass("mystate");

$scope.$on("$destroy", function() {
  $("body").removeClass("mystate"); 
});

This will add a class to my body tag when the state loads, and remove it when the state is destroyed (i.e. someone changes pages). This solves my related problem of only needing CSS to be applied to one state in my application.

this worked nicely for me:

from csv import DictReader

f = requests.get('https://somedomain.com/file').content.decode('utf-8')
reader = DictReader(f.split('\n'))
csv_dict_list = list(reader)

I came here looking for a simple way to let the user, when focused on an input, use the arrow keys to +1 or -1 a numeric input. I never found a good answer but made the following code that seems to work great - making this site-wide now.

$("input").bind('keydown', function (e) {
    if(e.keyCode == 40 && $.isNumeric($(this).val()) ) {
        $(this).val(parseFloat($(this).val())-1.0);
    } else if(e.keyCode == 38  && $.isNumeric($(this).val()) ) { 
        $(this).val(parseFloat($(this).val())+1.0);
    }
}); 

success has been the traditional name of the success callback in jQuery, defined as an option in the ajax call. However, since the implementation of $.Deferreds and more sophisticated callbacks, done is the preferred way to implement success callbacks, as it can be called on any deferred.

For example, success:

$.ajax({
  url: '/',
  success: function(data) {}
});

For example, done:

$.ajax({url: '/'}).done(function(data) {});

The nice thing about done is that the return value of $.ajax is now a deferred promise that can be bound to anywhere else in your application. So let's say you want to make this ajax call from a few different places. Rather than passing in your success function as an option to the function that makes this ajax call, you can just have the function return $.ajax itself and bind your callbacks with done, fail, then, or whatever. Note that always is a callback that will run whether the request succeeds or fails. done will only be triggered on success.

For example:

function xhr_get(url) {

  return $.ajax({
    url: url,
    type: 'get',
    dataType: 'json',
    beforeSend: showLoadingImgFn
  })
  .always(function() {
    // remove loading image maybe
  })
  .fail(function() {
    // handle request failures
  });

}

xhr_get('/index').done(function(data) {
  // do stuff with index data
});

xhr_get('/id').done(function(data) {
  // do stuff with id data
});

An important benefit of this in terms of maintainability is that you've wrapped your ajax mechanism in an application-specific function. If you decide you need your $.ajax call to operate differently in the future, or you use a different ajax method, or you move away from jQuery, you only have to change the xhr_get definition (being sure to return a promise or at least a done method, in the case of the example above). All the other references throughout the app can remain the same.

There are many more (much cooler) things you can do with $.Deferred, one of which is to use pipe to trigger a failure on an error reported by the server, even when the $.ajax request itself succeeds. For example:

function xhr_get(url) {

  return $.ajax({
    url: url,
    type: 'get',
    dataType: 'json'
  })
  .pipe(function(data) {
    return data.responseCode != 200 ?
      $.Deferred().reject( data ) :
      data;
  })
  .fail(function(data) {
    if ( data.responseCode )
      console.log( data.responseCode );
  });
}

xhr_get('/index').done(function(data) {
  // will not run if json returned from ajax has responseCode other than 200
});

Read more about $.Deferred here: http://api.jquery.com/category/deferred-object/

NOTE: As of jQuery 1.8, pipe has been deprecated in favor of using then in exactly the same way.

Here's a mixin that you can mix into any model class which gives each instance an update method:

class UpdateMixin(object):
    def update(self, **kwargs):
        if self._state.adding:
            raise self.DoesNotExist
        for field, value in kwargs.items():
            setattr(self, field, value)
        self.save(update_fields=kwargs.keys())

The self._state.adding check checks to see if the model is saved to the database, and if not, raises an error.

(Note: This update method is for when you want to update a model and you know the instance is already saved to the database, directly answering the original question. The built-in update_or_create method featured in Platinum Azure's answer already covers the other use-case.)

You would use it like this (after mixing this into your user model):

user = request.user
user.update(favorite_food="ramen")

Besides having a nicer API, another advantage to this approach is that it calls the pre_save and post_save hooks, while still avoiding atomicity issues if another process is updating the same model.

Poppy can gather not only the stack trace, but also parameter values, local variables, etc. - everything leading to the crash.

If it can't find explorer.exe, you should get an exception. If it can't find the folder, it should still open some folder (eg my Documents)

You say another copy of Explorer appears in the taskmanager, but you can't see it.

Is it possible that it is opening offscreen (ie another monitor)?

Or are you by any chance doing this in a non-interactive service?

${#str_var}  

where str_var is your string.

Assuming you are talking about this js in browser environment (unlike others like nodejs), Unfortunately I think what you are trying to do isn't possible simply because this is not the way it is supposed to work.

Html pages are delivered to the browser via HTTP Protocol, which is a 'stateless' protocol. If you still needed to pass values in between pages, there could be 3 approaches:

1. Session Cookies
2. HTML5 LocalStorage
3. POST the variable in the url and retrieve them in next.html via window object

The 'V' of HSV is probably what you're looking for. MATLAB has an rgb2hsv function and the previously cited wikipedia article is full of pseudocode. If an RGB2HSV conversion is not feasible, a less accurate model would be the grayscale version of the image.

HTML

  <div class="fileUpload btn btn-primary">
    <label class="upload">
      <input name='Image' type="file"/>

  </div>

CSS

input[type="file"]
{
  display: none;
}
.fileUpload input.upload

Note: Btn btn-primary is a class of bootstrap button. However the button may look weired in position. Hope you can fix it by inline css.

You create the same maps.

But you can fill the difference when you will use it. With first case you'll be able to use special HashMap methods (but I don't remember anyone realy useful), and you'll be able to pass it as a HashMap parameter:

public void foo (HashMap<String, Object) { ... }

HashMap<String, Object> m1 = ...;

Simple :::

scp remoteusername@remoteIP:/path/of/file /Local/path/to/copy

scp -r remoteusername@remoteIP:/path/of/folder /Local/path/to/copy

Every solution posted here assumes that you know the dimensions of your img, which is not a common scenario. Also, planting the dimensions into the solution is painful.

Simply set:

/* for the img inside your div */
display: block;
margin-left: auto;
margin-right: auto;

or

/* for the img inside your div */
display: block;
margin: 0 auto;

That's all.

Note, that you'll also have to set an initial min-width for your outer div.

If the indices match then:

df['B'] = df1['E']

should work otherwise:

df['B'] = df1['E'].values

will work so long as the length of the elements matches

php artisan make:model PurchaseRequest -crm

The Result is

Model created successfully.
Created Migration: 2018_11_11_011541_create_purchase_requests_table
Controller created successfully.

Just use -crm instead of -mcr

More oftenly most of the applications will have data,display and processing part and we just put all those in the letters M,V and C.

Model(M)-->Has the attributes that holds state of application and it dont know any thing about V and C.

View(V)-->Has displaying format for the application and and only knows about how-to-digest model on it and does not bother about C.

Controller(C)---->Has processing part of application and acts as wiring between M and V and it depends on both M,V unlike M and V.

Altogether there is separation of concern between each. In future any change or enhancements can be added very easily.

For a certain column, if you don't care about the ordering, use this

df['col1_num'] = df['col1'].apply(lambda x: np.where(df['col1'].unique()==x)[0][0])

If you care about the ordering, specify them as a list and use this

df['col1_num'] = df['col1'].apply(lambda x: ['first', 'second', 'third'].index(x))

For Apache Cassandra 2.0 you need to take into account the following TCP ports: (See EC2 security group configuration and Apache Cassandra FAQ)

Cassandra

• 7199 JMX monitoring port
• 1024 - 65355 Random port required by JMX. Starting with Java 7u4 a specific port can be specified using the com.sun.management.jmxremote.rmi.port property.
• 7000 Inter-node cluster
• 7001 SSL inter-node cluster
• 9042 CQL Native Transport Port
• 9160 Thrift

DataStax OpsCenter

• 61620 opscenterd daemon
• 61621 Agent
• 8888 Website

Architecture

A possible architecture with Cassandra + OpsCenter on EC2 could look like this:

Try setting the z-index higher on the contained element.

Use the square bracket syntax:

if (!empty($row["title"])) {
    $catList[$row["datasource_id"]] = $row["title"];
}

$row["datasource_id"] is the key for where the value of $row["title"] is stored in.

File > Import > General > Existing Projects into workspace. Select the root folder that has your project(s). It lists all the projects available in the selected folder. Select the ones you would like to import and click Finish. This should work just fine.

Try this code

HashMap<String, String> map = new HashMap<String, String>();
map.put("EmpID", EmpID);
map.put("UnChecked", "1");

I have found a way to use <base> and anchor based links. You can use JavaScript to keep links like #contact working as they have to. I used it in some parallax pages and it works for me.

<base href="http://www.mywebsite.com/templates/"><!--[if lte IE 6]></base><![endif]-->

...content...

<script>
var link='',pathname = window.location.href;
$('a').each(function(){
    link = $(this).attr('href');
    if(link[0]=="#"){
        $(this).attr('href', pathname + link);
    }
});
</script>

You should use at the end of the page

Other problem that might be causing such behavior are build configurations.

I had two projects with configurations set to be built to specific folders. Like Debug and Any CPU and in second it was Debug and x86.

What I did I went to Solution->Context menu->Properties->Configuration properties->Configuration and I set all my projects to use same configurations Debug and x86 and also checked Build tick mark.

Then projects started to build correctly and were able to see namespaces.

You may want to look at IBExpert Personal Edition. While not open source, this is a very good tool for designing, building, and administering Firebird and InterBase databases.

The Personal Edition is free, but some of the more advanced features are not available. Still, even without the slick extras, the free version is very powerful.

In my cases, for windows, if you have multiple python versions installed, if PYTHONPATH is pointing to one version the other ones didn't work. I found that if you just remove PYTHONPATH, they all work fine

I had a similar issue to solve in an app and I used the following method. I didn't use notifications for handling the navigation.

I have three storyboards in the app.

1. Splash screen storyboard - for app initialisation and checking if the user is already logged in
2. Login storyboard - for handling user login flow
3. Tab bar storyboard - for displaying the app content

My initial storyboard in the app is Splash screen storyboard. I have navigation controller as the root of login and tab bar storyboard to handle view controller navigations.

I created a Navigator class to handle the app navigation and it looks like this:

class Navigator: NSObject {

   static func moveTo(_ destinationViewController: UIViewController, from sourceViewController: UIViewController, transitionStyle: UIModalTransitionStyle? = .crossDissolve, completion: (() -> ())? = nil) {
       

       DispatchQueue.main.async {

           if var topController = UIApplication.shared.keyWindow?.rootViewController {

               while let presentedViewController = topController.presentedViewController {

                   topController = presentedViewController

               }

               
               destinationViewController.modalTransitionStyle = (transitionStyle ?? nil)!

               sourceViewController.present(destinationViewController, animated: true, completion: completion)

           }

       }

   }

}

Let's look at the possible scenarios:

• First app launch; Splash screen will be loaded where I check if the user is already signed in. Then login screen will be loaded using the Navigator class as follows;

Since I have navigation controller as the root, I instantiate the navigation controller as initial view controller.

let loginSB = UIStoryboard(name: "splash", bundle: nil)

let loginNav = loginSB.instantiateInitialViewcontroller() as! UINavigationController

Navigator.moveTo(loginNav, from: self)

This removes the slpash storyboard from app window's root and replaces it with login storyboard.

From login storyboard, when the user is successfully logged in, I save the user data to User Defaults and initialize a UserData singleton to access the user details. Then Tab bar storyboard is loaded using the navigator method.

Let tabBarSB = UIStoryboard(name: "tabBar", bundle: nil)
let tabBarNav = tabBarSB.instantiateInitialViewcontroller() as! UINavigationController

Navigator.moveTo(tabBarNav, from: self)

Now the user signs out from the settings screen in tab bar. I clear all the saved user data and navigate to login screen.

let loginSB = UIStoryboard(name: "splash", bundle: nil)

let loginNav = loginSB.instantiateInitialViewcontroller() as! UINavigationController

Navigator.moveTo(loginNav, from: self)

• User is logged in and force kills the app

When user launches the app, Splash screen will be loaded. I check if user is logged in and access the user data from User Defaults. Then initialize the UserData singleton and shows tab bar instead of login screen.

For me / had to be in a new line.

For example

create type emp_t;/

didn't work

but

create type emp_t;

/

worked.

You need to place the \n in double quotes.
Inside single quotes it is treated as 2 characters '\' followed by 'n'

You need:

$str = str_replace("\n", '', $str);

A better alternative is to use PHP_EOL as:

$str = str_replace(PHP_EOL, '', $str);

For the django version 1.9,I added

'DIRS': [os.path.join(BASE_DIR, 'templates')], 

line to the Templates block in settings.py And it worked well

If you want to use requirements.txt file, you will need git and something like the entry below to anonymously fetch the master branch in your requirements.txt.

For regular install:

git+git://github.com/celery/django-celery.git

For "editable" install:

-e git://github.com/celery/django-celery.git#egg=django-celery

Editable mode downloads the project's source code into ./src in the current directory. It allows pip freeze to output the correct github location of the package.

I tested as follows:

import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()

t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0

t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0

I got

$ python test.py

Given that Windows has no sys/socket.h, you might consider just doing something like this:

#ifdef __WIN32__
# include <winsock2.h>
#else
# include <sys/socket.h>
#endif

I know you indicated that you won't use WinSock, but since WinSock is how TCP networking is done under Windows, I don't see that you have any alternative. Even if you use a cross-platform networking library, that library will be calling WinSock internally. Most of the standard BSD sockets API calls are implemented in WinSock, so with a bit of futzing around, you can make the same sockets-based program compile under both Windows and other OS's. Just don't forget to do a

#ifdef __WIN32__
   WORD versionWanted = MAKEWORD(1, 1);
   WSADATA wsaData;
   WSAStartup(versionWanted, &wsaData);
#endif

at the top of main()... otherwise all of your socket calls will fail under Windows, because the WSA subsystem wasn't initialized for your process.

@Steve Farthing's answer is absolutely right.

But if you rotate more than 4 times then the image will get cropped from both the side. For that you need to do like this.

$("#clockwise").click(function(){ 
    angleInDegrees+=90 % 360;
    drawRotated(angleInDegrees);
    if(angleInDegrees == 360){  // add this lines
        angleInDegrees = 0
    }
});

Then you will get the desired result. Thanks. Hope this will help someone :)

You have defined 5 fields in your control file. Your fields are terminated by a comma, so you need 5 commas in each record for the 5 fields unless TRAILING NULLCOLS is specified, even though you are loading the ID field with a sequence value via the SQL String.

RE: Comment by OP

That's not my experience with a brief test. With the following control file:

load data
infile *
into table T_new
fields terminated by "," optionally enclosed by '"'
( A,
  B,
  C,
  D,
  ID "ID_SEQ.NEXTVAL"
)
BEGINDATA
1,1,,,
2,2,2,,
3,3,3,3,
4,4,4,4,,
,,,,,

Produced the following output:

Table T_NEW, loaded from every logical record.
Insert option in effect for this table: INSERT

Record 1: Rejected - Error on table T_NEW, column ID.

Record 2: Rejected - Error on table T_NEW, column ID.
Column not found before end of logical record (use TRAILING NULLCOLS)
Record 3: Rejected - Error on table T_NEW, column ID.
Column not found before end of logical record (use TRAILING NULLCOLS)
Record 5: Discarded - all columns null.

Table T_NEW:
  1 Row successfully loaded.
  3 Rows not loaded due to data errors.
  0 Rows not loaded because all WHEN clauses were failed.
  1 Row not loaded because all fields were null.

Note that the only row that loaded correctly had 5 commas. Even the 3rd row, with all data values present except ID, the data does not load. Unless I'm missing something...

I'm using 10gR2.

what about changing the position: relative on your #content #text div to position: absolute

#content #text {
   position:absolute;
   width:950px;
   height:215px;
   color:red;
}

http://jsfiddle.net/CaZY7/12/

then you can use the css properties left and top to position within the #content div

If you can use numpy, then you can delete multiple indices:

>>> import numpy as np
>>> a = np.arange(10)
>>> np.delete(a,(1,3,5))
array([0, 2, 4, 6, 7, 8, 9])

and if you use np.r_ you can combine slices with individual indices:

>>> np.delete(a,(np.r_[0:5,7,9]))
array([5, 6, 8])

However, the deletion is not in place, so you have to assign to it.

Usually in Linux you use crontab for this kind of scduled tasks. But you have to specify the time when you "setup the timer" - so if you want it to be configurable in the file itself, you will have to create some mechanism to do that.

But in general, you would use for example:

30 1 * * 5 /path/to/script/script.sh

Would execute the script every Friday at 1:30 (AM) Here:

30 is minutes

1 is hour

next 2 *'s are day of month and month (in that order) and 5 is weekday

In handlebar version 3.0 onwards,

{{#each users as |user userId|}}
  Id: {{userId}} Name: {{user.name}}
{{/each}}

In this particular example, user will have the same value as the current context and userId will have the index value for the iteration. Refer - http://handlebarsjs.com/block_helpers.html in block helpers section

Please check in logs if you have http.HttpWagon$__sisu1:Cannot find 'basicAuthScope' this error or warning also, if so you need to use maven 3.2.5 version, which will resolve error.

the css you are showing must be applied to a block element, like a div. So :

<div id="#rectangle"></div>

I don't believe the expression is sensical as it is.

Elvis means "if truthy, use the value, else use this other thing."

Your "other thing" is a closure, and the value is status != null, neither of which would seem to be what you want. If status is null, Elvis says true. If it's not, you get an extra layer of closure.

Why can't you just use:

(it.description == desc) && ((status == null) || (it.status == status))

Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find calls, just use an intermediate variable.

    INSERT INTO Persons_Table (person_id, person_name,person_email)
          SELECT person_id, customer_name, customer_email
          FROM customer_table
          WHERE "insert your where clause here";
    DELETE FROM customer_table
          WHERE "repeat your where clause here";

If you know you're going offline for a while, you can close your connection, do your processing, reconnect and write your reports.

Stroke length depends on stroke width. You can increase length by increasing width and hide part of border by inner element.

Like the OP, I was looking for a Windows folder diff tool, in particular one that could handle very large trees (100s of Gigabytes of data). Thanks Lieven Keersmaekers for the pointer to BeyondCompare, which I found to be VERY fast (roughly 10-100 times faster) than my previous old school tool windiff.

BTW, BeyondCompare does have a command line mode in addition to the GUI.

I used the below work around for long - not sure about its complexity.

s.erase(std::unique(s.begin(),s.end(),[](char s,char f){return (f==' '||s==' ');}),s.end());

when you wanna remove character ' ' and some for example - use

s.erase(std::unique(s.begin(),s.end(),[](char s,char f){return ((f==' '||s==' ')||(f=='-'||s=='-'));}),s.end());

likewise just increase the || if number of characters you wanna remove is not 1

but as mentioned by others the erase remove idiom also seems fine.

How about this:

public static long nextLong(@NonNull Random r, long min, long max) {
    if (min > max)
        throw new IllegalArgumentException("min>max");
    if (min == max)
        return min;
    long n = r.nextLong();
    //abs (use instead of Math.abs, which might return min value) :
    n = n == Long.MIN_VALUE ? 0 : n < 0 ? -n : n;
    //limit to range:
    n = n % (max - min);
    return min + n;
}

?

How about this :
I used CustomViewPager
and next, override scrollTo method
I checked the movement when doing a lot of small swipes, it doesn't scroll to other pages.

public class CustomViewPager extends ViewPager {

    private boolean enabled;

    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.enabled = true;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (this.enabled) {
            return super.onTouchEvent(event);
        }

        return false;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        if (this.enabled) {
            return super.onInterceptTouchEvent(event);
        }

        return false;
    }

    public void setPagingEnabled(boolean enabled) {
        this.enabled = enabled;
    } 

    @Override
    public void scrollTo(int x, int y) {
       if(enabled) {
          super.scrollTo(x, y);
       }
    }
}

You can do it in StatTransfer, R or perl (as mentioned by others), but StatTransfer costs $$$ and R/Perl have a learning curve.
There is a free, menu-driven stats program from AM Statistical Software that can open and convert Stata .dta from all versions of Stata, see:

Tried deleting IISExpress folder, changed port , restart VS and PC but it didn't work. However it worked after killing iisexpress.exe service in services.

If the data to be encoded contains "exotic" characters, I think you have to encode in "UTF-8"

encoded = base64.b64encode (bytes('data to be encoded', "utf-8"))

It seems like your query returns more than one result check the database. In documentation of query.uniqueResult() you can read:

Throws: org.hibernate.NonUniqueResultException - if there is more than one matching result

If you want to avoid this error and still use unique result request, you can use this kind of workaround query.setMaxResults(1).uniqueResult();

The main disadvantage of the #define method is that the string is duplicated each time it is used, so you can end up with lots of copies of it in the executable, making it bigger.

Use req.app, req.app.get('somekey')

The application variable created by calling express() is set on the request and response objects.

See: https://github.com/visionmedia/express/blob/76147c78a15904d4e4e469095a29d1bec9775ab6/lib/express.js#L34-L35

use .empty()

 $('select').empty().append('whatever');

you can also use .html() but note

When .html() is used to set an element's content, any content that was in that element is completely replaced by the new content. Consider the following HTML:

alternative: --- If you want only option elements to-be-remove, use .remove()

$('select option').remove();

SELECT 'DROP TABLE "' || TABLE_NAME || '" CASCADE CONSTRAINTS;' 
FROM user_tables;

user_tables is a system table which contains all the tables of the user the SELECT clause will generate a DROP statement for every table you can run the script

based on Vivek's answer, but I think the following would be better:

@Component("applicationContextProvider")
public class ApplicationContextProvider implements ApplicationContextAware {

    private static class AplicationContextHolder{

        private static final InnerContextResource CONTEXT_PROV = new InnerContextResource();

        private AplicationContextHolder() {
            super();
        }
    }

    private static final class InnerContextResource {

        private ApplicationContext context;

        private InnerContextResource(){
            super();
        }

        private void setContext(ApplicationContext context){
            this.context = context;
        }
    }

    public static ApplicationContext getApplicationContext() {
        return AplicationContextHolder.CONTEXT_PROV.context;
    }

    @Override
    public void setApplicationContext(ApplicationContext ac) {
        AplicationContextHolder.CONTEXT_PROV.setContext(ac);
    }
}

Writing from an instance method to a static field is a bad practice and dangerous if multiple instances are being manipulated.

What about the following?

print testlist.index(element)

If you are not sure whether the element to look for is actually in the list, you can add a preliminary check, like

if element in testlist:
    print testlist.index(element)

or

print(testlist.index(element) if element in testlist else None)

or the "pythonic way", which I don't like so much because code is less clear, but sometimes is more efficient,

try:
    print testlist.index(element)
except ValueError:
    pass

Print a string as hex bytes?

The accepted answer gives:

s = "Hello world !!"
":".join("{:02x}".format(ord(c)) for c in s)

returns:

'48:65:6c:6c:6f:20:77:6f:72:6c:64:20:21:21'

The accepted answer works only so long as you use bytes (mostly ascii characters). But if you use unicode, e.g.:

a_string = u"?????? ???!!" # "Prevyet mir", or "Hello World" in Russian.

You need to convert to bytes somehow.

If your terminal doesn't accept these characters, you can decode from UTF-8 or use the names (so you can paste and run the code along with me):

a_string = (
    "\N{CYRILLIC CAPITAL LETTER PE}"
    "\N{CYRILLIC SMALL LETTER ER}"
    "\N{CYRILLIC SMALL LETTER I}"
    "\N{CYRILLIC SMALL LETTER VE}"
    "\N{CYRILLIC SMALL LETTER IE}"
    "\N{CYRILLIC SMALL LETTER TE}"
    "\N{SPACE}"
    "\N{CYRILLIC SMALL LETTER EM}"
    "\N{CYRILLIC SMALL LETTER I}"
    "\N{CYRILLIC SMALL LETTER ER}"
    "\N{EXCLAMATION MARK}"
    "\N{EXCLAMATION MARK}"
)

So we see that:

":".join("{:02x}".format(ord(c)) for c in a_string)

returns

'41f:440:438:432:435:442:20:43c:438:440:21:21'

a poor/unexpected result - these are the code points that combine to make the graphemes we see in Unicode, from the Unicode Consortium - representing languages all over the world. This is not how we actually store this information so it can be interpreted by other sources, though.

To allow another source to use this data, we would usually need to convert to UTF-8 encoding, for example, to save this string in bytes to disk or to publish to html. So we need that encoding to convert the code points to the code units of UTF-8 - in Python 3, ord is not needed because bytes are iterables of integers:

>>> ":".join("{:02x}".format(c) for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'

Or perhaps more elegantly, using the new f-strings (only available in Python 3):

>>> ":".join(f'{c:02x}' for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'

In Python 2, pass c to ord first, i.e. ord(c) - more examples:

>>> ":".join("{:02x}".format(ord(c)) for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'
>>> ":".join(format(ord(c), '02x') for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'

TypeScript 0.9+ has a specification for enums:

enum AnimationType {
    BOUNCE,
    DROP,
}

The final comma is optional.

The [] operator is called an indexer. You can provide indexers that take an integer, a string, or any other type you want to use as a key. The syntax is straightforward, following the same principles as property accessors.

For example, in your case where an int is the key or index:

public int this[int index]
{
    get => GetValue(index);
}

You can also add a set accessor so that the indexer becomes read and write rather than just read-only.

public int this[int index]
{
    get => GetValue(index);
    set => SetValue(index, value);
}

If you want to index using a different type, you just change the signature of the indexer.

public int this[string index]
...

ALL_CONSTRAINTS describes constraint definitions on tables accessible to the current user.

As far as you're concerned once you've "pulled out" the contents with something like .html() it's just a string. You can test that with

<html> 
  <head>
    <title>runthis</title>
    <script type="text/javascript" language="javascript" src="jquery-1.3.2.js"></script>
    <script type="text/javascript">
        $(document).ready( function() {
            var x = $("#foo").html();
            alert( typeof(x) );
        });
    </script>
    </head>
    <body>
        <div id="foo"><table><tr><td>x</td></tr></table><span>xyz</span></div>
    </body>
</html>

The alert text is string. As long as you don't pass it to a parser there's no magic about it, it's a string like any other string.
There's nothing that hinders you from using .post() to send this string back to the server.

edit: Don't pass a string as the parameter data to .post() but an object, like

var data = {
  id: currid,
  html: div_html
};
$.post("http://...", data, ...);

jquery will handle the encoding of the parameters.
If you (for whatever reason) want to keep your string you have to encode the values with something like escape().

var data = 'id='+ escape(currid) +'&html='+ escape(div_html);

I think you'll struggle with keyup event - as it first triggers keypress - and you won't be able to stop the propagation of the second one if you want to exclude the Enter Key.

From wikipedia:

In computer science, an array data structure or simply array is a data structure consisting of a collection of elements (values or variables), each identified by one or more integer indices, stored so that the address of each element can be computed from its index tuple by a simple mathematical formula.

So when you say byte array, you're referring to an array of some defined length (e.g. number of elements) that contains a collection of byte (8 bits) sized elements.

In C# a byte array could look like:

byte[] bytes = { 3, 10, 8, 25 };

The sample above defines an array of 4 elements, where each element can be up to a Byte in length.

I am not getting your question properly but as per your heading, you can convert any type of object to string by using toString() function on a String Object.

In the command line type service apache2 status then hit enter. The result should say:

Apache2 is running (pid xxxx)

For those who wants a short method (with limitations):

location.search.split('myParameter=')[1]

You can't. You have to have a separate div that is just that background, so that you can only apply the opacity to that.

I tried doing this recently, and since I was already using jQuery, I found the following to be the least hassle:

1. Create the two different divs. They'll be siblings, not contained in each other or anything.
2. Give the text div a solid background color, because that will be the JavaScript-less default.
3. Use jQuery to get the text div's height, and apply it to the background div.

I'm sure there's some kind of CSS ninja way to do all this with only floats or something, but I didn't have the patience to figure it out.

Or see cut_number from the ggplot2 package, e.g.

das$wt_2 <- as.numeric(cut_number(das$wt,3))

Note that cut(...,3) divides the range of the original data into three ranges of equal lengths; it doesn't necessarily result in the same number of observations per group if the data are unevenly distributed (you can replicate what cut_number does by using quantile appropriately, but it's a nice convenience function). On the other hand, Hmisc::cut2() using the g= argument does split by quantiles, so is more or less equivalent to ggplot2::cut_number. I might have thought that something like cut_number would have made its way into dplyr by so far, but as far as I can tell it hasn't.

>>> import re
>>> string1 = "498results should get"
>>> int(re.search(r'\d+', string1).group())
498

If there are multiple integers in the string:

>>> map(int, re.findall(r'\d+', string1))
[498]

My solution works with MySQL date time formats and provides a callback function. on complition. Disclaimer: works only with minutes and seconds, as this is what I needed.

jQuery.fn.countDownTimer = function(futureDate, callback){
    if(!futureDate){
        throw 'Invalid date!';
    }

    var currentTs = +new Date();
    var futureDateTs = +new Date(futureDate);

    if(futureDateTs <= currentTs){
        throw 'Invalid date!';
    }


    var diff = Math.round((futureDateTs - currentTs) / 1000);
    var that = this;

    (function countdownLoop(){
        // Get hours/minutes from timestamp
        var m = Math.floor(diff % 3600 / 60);
        var s = Math.floor(diff % 3600 % 60);
        var text = zeroPad(m, 2) + ':' + zeroPad(s, 2);

        $(that).text(text);

        if(diff <= 0){
            typeof callback === 'function' ? callback.call(that) : void(0);
            return;
        }

        diff--;
        setTimeout(countdownLoop, 1000);
    })();

    function zeroPad(num, places) {
      var zero = places - num.toString().length + 1;
      return Array(+(zero > 0 && zero)).join("0") + num;
    }
}

// $('.heading').countDownTimer('2018-04-02 16:00:59', function(){ // on complete})

I created my own jQuery plugin after becoming frustrated that the existing shims would hide the placeholder on focus, which creates an inferior user experience and also does not match how Firefox, Chrome and Safari handle it. This is especially the case if you want an input to be focused when a page or popup first loads, while still showing the placeholder until text is entered.

Simply:

// Default export (recommended)
export {default} from './MyClass' 

// Default export with alias
export {default as d1} from './MyClass' 

// In >ES7, it could be
export * from './MyClass'

// In >ES7, with alias
export * as d1 from './MyClass'

Or by functions names :

// export by function names
export { funcName1, funcName2, …} from './MyClass'

// export by aliases
export { funcName1 as f1, funcName2 as f2, …} from './MyClass'

Replacing spaces is fine, but I might suggest going a little further to handle other URL-hostile characters like question marks, apostrophes, exclamation points, etc.

Also note that the general consensus among SEO experts is that dashes are preferred to underscores in URLs.

import re

def urlify(s):

    # Remove all non-word characters (everything except numbers and letters)
    s = re.sub(r"[^\w\s]", '', s)

    # Replace all runs of whitespace with a single dash
    s = re.sub(r"\s+", '-', s)

    return s

# Prints: I-cant-get-no-satisfaction"
print(urlify("I can't get no satisfaction!"))

Suppose your programming logic depends on whether a dictionary has an entry with a given key. You can test the result of dict.get(key) using if... else... construct, or you can do:

try:
    val = dic[key]
except KeyError:
    do_some_stuff()
else:
    do_some_stuff_with_val(val)

According to Josh Staiger, Mac OS X's Terminal.app actually runs a login shell rather than a non-login shell by default for each new terminal window, calling .bash_profile instead of .bashrc.

He recommends:

Most of the time you don’t want to maintain two separate config files for login and non-login shells — when you set a PATH, you want it to apply to both. You can fix this by sourcing .bashrc from your .bash_profile file, then putting PATH and common settings in .bashrc.

To do this, add the following lines to .bash_profile:

if [ -f ~/.bashrc ]; then 
    source ~/.bashrc 
fi

Now when you login to your machine from a console .bashrc will be called.

It is not certain that any global ECMAScript variables have been exported and html/css does not necessarily indicate React. So look in the .js.

Method 1: Look in ECMAScript:

The version number is exported by both modules react-dom and react but those names are often removed by bundling and the version hidden inside an execution context that cannot be accessed. A clever break point may reveal the value directly, or you can search the ECMAScript:

1. Load the Web page (you can try https://www.instagram.com they’re total Coolaiders)
2. Open Chrome Developer Tools on Sources tab (control+shift+i or command+shift+i)
   1. Dev tools open on the Sources tab
3. In the very right of the top menu bar, click the vertical ellipsis and select search all files
4. In he search box down on left type FIRED in capital letters, clear the checkbox Ignore case, type Enter
   1. One or more matches appear below. The version is an export very close to the search string looking like version: "16.0.0"
5. If the version number is not immediately visible: double click a line that begins with a line number
   1. ECMAScript appears in the middle pane
6. If the version number is not immediately visible: click the two braces at bottom left of the ECMAScript pane {}
   1. ECMAScript is reformatted and easier to read
7. If the version number is not immediately visible: scroll up and down a few lines to find it or try another search key
   1. If the code is not minified, search for ReactVersion There should be 2 hits with the same value
   2. If the code is minified, search for either SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED or react-dom
   3. Or search for the likely version string itself: "15. or "16. or even "0.15

Method 2: Use a DOM breakpoint:

1. Load the page rendered by React
2. Right click a React element (anything, like an input field or a box) and select Inspect Element
   1. Chrome Developer Tools displays the Elements pane
3. As high up in the tree as possible from the selected element, but no higher than the React root element (often a div directly inside body with id root: <div id="root">), right click an element and select Break On… - subtree modifications
   1. Note: It is possible to compare contents of the Elements tab (DOM current state) with the response for the same resouce on the Networks tab. This may reveal React’s root element
4. Reload the page by clicking Reload left of the address bar
   1. Chrome Developer Tools stops at the breakpoint and displays the Sources pane
5. In the rightmost pane, examine the Call Stack sub-pane
6. As far down the call stack as possible, there should be a render entry, this is ReactDOM.render
7. Click the line below render, ie. the code that invokes render
8. The middle pane now displays ECMAScript with an expression containing .render highlighted
9. Hover the mouse cursor over the object used to invoke render, is. the react-dom module exports object
   1. if the code line goes: Object(u.render)(…, hover over the u
10. A tooltip window is displayed containing version: "15.6.2", ie. all values exported by react-dom

The version is also injected into React dev tools, but as far as I know not displayed anywhere.

Alternatively, you can cast the row DataItem to a class and then add condition based on the class properties. Here is a sample that I used to convert the row to a class/model named TimetableModel, then in if statement you have access to all class fields/properties:

protected void GridView_TimeTable_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    var tt = (TimetableModel)(e.Row.DataItem);
                     if (tt.Unpublsihed )
                       e.Row.BackColor = System.Drawing.Color.Red;
                     else
                       e.Row.BackColor = System.Drawing.Color.Green;
                }
            }
        }

Java 8:

String[] strArray = {"eins", "zwei", "drei", "vier"};

Set<String> strSet = Arrays.stream(strArray).collect(Collectors.toSet());
System.out.println(strSet);
// [eins, vier, zwei, drei]

In woocommerce,

Get regular price :

$price = get_post_meta( get_the_ID(), '_regular_price', true);
// $price will return regular price

Get sale price:

$sale = get_post_meta( get_the_ID(), '_sale_price', true);
// $sale will return sale price

Another option is to do another "git stash" of the local uncommitted changes, then combine the two git stashes. Unfortunately git seems to not have a way to easily combine two stashes. So one option is to create two .diff files and apply them both--at lest its not an extra commit and doesn't involve a ten step process :|

You are right, this is related to SQL injection, which is a vulnerability that allows a malicioius user to execute arbitrary statements against your database. This old time favorite XKCD comic illustrates the concept:

In your example, if you just use:

var query = "SELECT empSalary from employee where salary = " + txtSalary.Text;
// and proceed to execute this query

You are open to SQL injection. For example, say someone enters txtSalary:

1; UPDATE employee SET salary = 9999999 WHERE empID = 10; --
1; DROP TABLE employee; --
// etc.

When you execute this query, it will perform a SELECT and an UPDATE or DROP, or whatever they wanted. The -- at the end simply comments out the rest of your query, which would be useful in the attack if you were concatenating anything after txtSalary.Text.

The correct way is to use parameterized queries, eg (C#):

SqlCommand query =  new SqlCommand("SELECT empSalary FROM employee 
                                    WHERE salary = @sal;");
query.Parameters.AddWithValue("@sal", txtSalary.Text);

With that, you can safely execute the query.

For reference on how to avoid SQL injection in several other languages, check bobby-tables.com, a website maintained by a SO user.
