1. Go to Project Root Directory Package.json file

2. add "type":"module";

3. Save it and Restart Server

Usually in case of "ImagePullBackOff" it's retried after few seconds/minutes. In case you want to try again manually you can delete the old pod and recreate the pod. The one line command to delete and recreate the pod would be:

kubectl replace --force -f <yml_file_describing_pod>

In a much simpler way, you can do the same using

from PIL import Image

image = Image.open('image.jpg')
image.show()

If it says the API key is listed as a header, more than likely you need to set it in the headers option of your http request. Normally something like this :

headers: {'Authorization': '[your API key]'}

Here is an example from another Question

$http({method: 'GET', url: '[the-target-url]', headers: {
  'Authorization': '[your-api-key]'}
});

Edit : Just saw you wanted to store the response in a variable. In this case I would probably just use AJAX. Something like this :

$.ajax({ 
   type : "GET", 
   url : "[the-target-url]", 
   beforeSend: function(xhr){xhr.setRequestHeader('Authorization', '[your-api-key]');},
   success : function(result) { 
       //set your variable to the result 
   }, 
   error : function(result) { 
     //handle the error 
   } 
 }); 

I got this from this question and I'm at work so I can't test it at the moment but looks solid

Edit 2: Pretty sure you should be able to use this line :

headers: {'Authorization': '[your API key]'},

instead of the beforeSend line in the first edit. This may be simpler for you

it would be great if somebody told to put gif into any folder instead of assets folder

You can turn the axes off by following the advice in Veedrac's comment (linking to here) with one small modification.

Rather than using plt.axis('off') you should use ax.axis('off') where ax is a matplotlib.axes object. To do this for your code you simple need to add axarr[0,0].axis('off') and so on for each of your subplots.

The code below shows the result (I've removed the prune_matrix part because I don't have access to that function, in the future please submit fully working code.)

import matplotlib.pyplot as plt
import matplotlib.image as mpimg
import matplotlib.cm as cm

img = mpimg.imread("stewie.jpg")

f, axarr = plt.subplots(2, 2)
axarr[0,0].imshow(img, cmap = cm.Greys_r)
axarr[0,0].set_title("Rank = 512")
axarr[0,0].axis('off')

axarr[0,1].imshow(img, cmap = cm.Greys_r)
axarr[0,1].set_title("Rank = %s" % 128)
axarr[0,1].axis('off')

axarr[1,0].imshow(img, cmap = cm.Greys_r)
axarr[1,0].set_title("Rank = %s" % 32)
axarr[1,0].axis('off')

axarr[1,1].imshow(img, cmap = cm.Greys_r)
axarr[1,1].set_title("Rank = %s" % 16)
axarr[1,1].axis('off')

plt.show()

Note: To turn off only the x or y axis you can use set_visible() e.g.:

axarr[0,0].xaxis.set_visible(False) # Hide only x axis

Since you return to the client just String and its content type == 'text/plain', there is no any chance for default converters to determine how to convert String response to the FFSampleResponseHttp object.

The simple way to fix it:

• remove expected-response-type from <int-http:outbound-gateway>
• add to the replyChannel1 <json-to-object-transformer>

Otherwise you should write your own HttpMessageConverter to convert the String to the appropriate object.

To make it work with MappingJackson2HttpMessageConverter (one of default converters) and your expected-response-type, you should send your reply with content type = 'application/json'.

If there is a need, just add <header-enricher> after your <service-activator> and before sending a reply to the <int-http:inbound-gateway>.

So, it's up to you which solution to select, but your current state doesn't work, because of inconsistency with default configuration.

UPDATE

OK. Since you changed your server to return FfSampleResponseHttp object as HTTP response, not String, just add contentType = 'application/json' header before sending the response for the HTTP and MappingJackson2HttpMessageConverter will do the stuff for you - your object will be converted to JSON and with correct contentType header.

From client side you should come back to the expected-response-type="com.mycompany.MyChannel.model.FFSampleResponseHttp" and MappingJackson2HttpMessageConverter should do the stuff for you again.

Of course you should remove <json-to-object-transformer> from you message flow after <int-http:outbound-gateway>.

In case you don't need javax.el (for example in a JavaSE application), use ParameterMessageInterpolator from Hibernate validator. Hibernate validator is a standalone component, which can be used without Hibernate itself.

Depend on hibernate-validator

<dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-validator</artifactId>
   <version>6.0.16.Final</version>
</dependency>

Use ParameterMessageInterpolator

import javax.validation.Validation;
import javax.validation.Validator;
import org.hibernate.validator.messageinterpolation.ParameterMessageInterpolator;

private static final Validator VALIDATOR =
  Validation.byDefaultProvider()
    .configure()
    .messageInterpolator(new ParameterMessageInterpolator())
    .buildValidatorFactory()
    .getValidator();

@Sheridan thx.. if I try your example with "DisplayedImagePath" on both sides, it works with absolute path as you show.

As for the relative paths, this is how I always connect relative paths, I first include the subdirectory (!) and the image file in my project.. then I use ~ character to denote the bin-path..

    public string DisplayedImagePath
    {
        get { return @"~\..\images\osc.png"; }
    }

This was tested, see below my Solution Explorer in VS2015..

)

Note: if you want a Click event, use the Button tag around the image,

<Button Click="image_Click" Width="128" Height="128"  Grid.Row="2" VerticalAlignment="Top" HorizontalAlignment="Left">_x000D_
  <Image x:Name="image" Source="{Binding DisplayedImagePath}" Margin="0,0,0,0" />_x000D_
</Button>

I removed the following entry from web.config and it worked for me.

<dependentAssembly>
                <assemblyIdentity name="System.Web.Http.WebHost" culture="neutral" publicKeyToken="31BF3856AD364E35" />
                <bindingRedirect oldVersion="0.0.0.0-65535.65535.65535.65535" newVersion="5.2.6.0" />
            </dependentAssembly>

My solution was to add a space between the $ and the {.

For example:

@Value("${project.ftp.adresse}")

becomes

@Value("$ {project.ftp.adresse}")

I was running on Win7, Tomcat7 with maven-pom setup on Eclipse Mars with maven project enabled. On a NOT running server I only had to change from 3.1 to 3.0 on this screen:

For me it was important to have Dynamic Web Module disabled! Then change the version and then enable Dynamic Web Module again.

If you don't want to make the button a separate image, you can use the <area> tag. This is done by using html similar to this:

<img src="imgsrc" width="imgwidth" height="imgheight" alt="alttext" usemap="#mapname">

<map name="mapname">
    <area shape="rect" coords="see note 1" href="link" alt="alttext">
</map>

Note 1: The coords=" " attribute must be formatted in this way: coords="x1,y1,x2,y2" where:

x1=top left X coordinate
y1=top left Y coordinate
x2=bottom right X coordinate
y2=bottom right Y coordinate

Note 2: The usemap="#mapname" attribute must include the #.

EDIT:

I looked at your code and added in the <map> and <area> tags where they should be. I also commented out some parts that were either overlapping the image or seemed there for no use.

<div class="flexslider">
    <ul class="slides" runat="server" id="Ul">                             
        <li class="flex-active-slide" style="background: url(&quot;images/slider-bg-1.jpg&quot;) no-repeat scroll 50% 0px transparent; width: 100%; float: left; margin-right: -100%; position: relative; display: list-item;">
            <div class="container">
                <div class="sixteen columns contain"></div>   
                <img runat="server" id="imgSlide1" style="top: 1px; right: -19px; opacity: 1;" class="item" src="./test.png" data-topimage="7%" height="358" width="728" usemap="#imgmap" />
                <map name="imgmap">
                    <area shape="rect" coords="48,341,294,275" href="http://www.example.com/">
                </map>
                <!--<a href="#" style="display:block; background:#00F; width:356px; height:66px; position:absolute; left:1px; top:-19px; left: 162px; top: 279px;"></a>-->

Notes:

1. The coord="48,341,294,275" is in reference to your screenshot you posted.
2. The src="./test.png" is the location and name of the screenshot you posted on my computer.
3. The href="http://www.example.com/" is an example link.

If you want to add a header to all Jersey responses, you could also use a ContainerResponseFilter, from Jersey's filter documentation :

import java.io.IOException;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerResponseContext;
import javax.ws.rs.container.ContainerResponseFilter;
import javax.ws.rs.core.Response;

@Provider
public class PoweredByResponseFilter implements ContainerResponseFilter {

    @Override
    public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext)
        throws IOException {

            responseContext.getHeaders().add("X-Powered-By", "Jersey :-)");
    }
}

Make sure that you initialize it correctly in your project using the @Provider annotation or through traditional ways with web.xml.

Check the C-drive inside C:\inetpub\wwwroot and remove all unnecessary folders from it, else remove unnecessary host files or folders from IIS.

I found that I also had to set the Access Modifier in the Resources tab to 'Public' - by default it was set to Internal and my icon only appeared in design mode but not when I ran the application.

When you have everything #included, an unresolved external symbol is often a missing * or & in the declaration or definition of a function.

The two int variables are defined in the header file. This means that every source file which includes the header will contain their definition (header inclusion is purely textual). The of course leads to multiple definition errors.

You have several options to fix this.

1. Make the variables static (static int WIDTH = 1024;). They will still exist in each source file, but their definitions will not be visible outside of the source file.

2. Turn their definitions into declarations by using extern (extern int WIDTH;) and put the definition into one source file: int WIDTH = 1024;.

3. Probably the best option: make the variables const (const int WIDTH = 1024;). This makes them static implicitly, and also allows them to be used as compile-time constants, allowing the compiler to use their value directly instead of issuing code to read it from the variable etc.

I found a really cool library, try this out. this is really smooth and easy to use.

An absolute URI specifies a scheme; a URI that is not absolute is said to be relative.

http://docs.oracle.com/javase/8/docs/api/java/net/URI.html

So, perhaps your URLEncoder isn't working as you're expecting (the https bit)?

    URLEncoder.encode(uri) 

use this:

pil_image = PIL.Image.open('Image.jpg').convert('RGB') 
open_cv_image = numpy.array(pil_image) 
# Convert RGB to BGR 
open_cv_image = open_cv_image[:, :, ::-1].copy() 

@GET does support List of Strings

Setup:
Java : 1.7
Jersey version : 1.9

Resource

@Path("/v1/test")

Subresource:

// receive List of Strings
@GET
@Path("/receiveListOfStrings")
public Response receiveListOfStrings(@QueryParam("list") final List<String> list){
    log.info("receieved list of size="+list.size());
    return Response.ok().build();
}

Jersey testcase

@Test
public void testReceiveListOfStrings() throws Exception {
    WebResource webResource = resource();
    ClientResponse responseMsg = webResource.path("/v1/test/receiveListOfStrings")
            .queryParam("list", "one")
            .queryParam("list", "two")
            .queryParam("list", "three")
            .get(ClientResponse.class);
    Assert.assertEquals(200, responseMsg.getStatus());
}

DENSE_RANK() is a rank with no gaps, i.e. it is “dense”.

select Name,EmailId,salary,DENSE_RANK() over(order by salary asc) from [dbo].[Employees]

RANK()-It contain gap between the rank.

select Name,EmailId,salary,RANK() over(order by salary asc) from [dbo].[Employees]

slf4j-log4j12 is the log4j binding for slf4j you dont need to add another log4j dependency.

</dependency>

if you are configuring slf4j due to some dependencies requiring it.

you could do:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.image as mpimg

def rgb_to_gray(img):
        grayImage = np.zeros(img.shape)
        R = np.array(img[:, :, 0])
        G = np.array(img[:, :, 1])
        B = np.array(img[:, :, 2])

        R = (R *.299)
        G = (G *.587)
        B = (B *.114)

        Avg = (R+G+B)
        grayImage = img

        for i in range(3):
           grayImage[:,:,i] = Avg

        return grayImage       

image = mpimg.imread("your_image.png")   
grayImage = rgb_to_gray(image)  
plt.imshow(grayImage)
plt.show()

In WPF an image is typically loaded from a Stream or an Uri.

BitmapImage supports both and an Uri can even be passed as constructor argument:

var uri = new Uri("http://...");
var bitmap = new BitmapImage(uri);

If the image file is located in a local folder, you would have to use a file:// Uri. You could create such a Uri from a path like this:

var path = Path.Combine(Environment.CurrentDirectory, "Bilder", "sas.png");
var uri = new Uri(path);

If the image file is an assembly resource, the Uri must follow the the Pack Uri scheme:

var uri = new Uri("pack://application:,,,/Bilder/sas.png");

In this case the Visual Studio Build Action for sas.png would have to be Resource.

Once you have created a BitmapImage and also have an Image control like in this XAML

<Image Name="image1" />

you would simply assign the BitmapImage to the Source property of that Image control:

image1.Source = bitmap;

After trying the above answers with no success (and a slew of other stack posts) what finally worked for me was just

plt.gca().set_axis_off()
plt.subplots_adjust(top = 1, bottom = 0, right = 1, left = 0, 
            hspace = 0, wspace = 0)
plt.margins(0,0)
plt.savefig("myfig.pdf")

Importantly this does not include the bbox or padding arguments.

If you want to run .py files in Windows, Try installing Git bash Then download python(Required Version) from python.org and install in the main c drive folder

For me, its :

"C:\Python38"

then open Git Bash and go to the respective folder where your .py file is stored :

For me, its :

File Location : "Downloads" File Name : Train.py

So i changed my Current working Directory From "C:/User/(username)/" to "C:/User/(username)/Downloads"

then i will run the below command

" /c/Python38/python Train.py "

and it will run successfully.

But if it give the below error :

from sklearn.model_selection import train_test_split ModuleNotFoundError: No module named 'sklearn'

Then Do not panic :

and use this command :

" /c/Python38/Scripts/pip install sklearn "

and after it has installed sklearn go back and run the previous command :

" /c/Python38/python Train.py "

and it will run successfully.

You can use general compound drawable implementation, but if you need to define a size of drawable use this library:

https://github.com/a-tolstykh/textview-rich-drawable

Here is a small example of usage:

<com.tolstykh.textviewrichdrawable.TextViewRichDrawable
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Some text"
        app:compoundDrawableHeight="24dp"
        app:compoundDrawableWidth="24dp" />

1. Go to the IIS Manager.
2. open the server name like (PC-Name)\.
3. then double click on the ISAPI and CGI Restriction.
4. then select ASP.NET v4.0.30319(32-bit) Restriction allowed.

Here is a jsfiddle

It provides the abbreviation of the current user timezone.

Here is the code sample

var tz = jstz.determine();
console.log(tz.name());
console.log(moment.tz.zone(tz.name()).abbr(new Date().getTime()));

When wrapping a pointer in a unique_ptr you cannot have multiple copies of unique_ptr. The shared_ptr holds a reference counter which count the number of copies of the stored pointer. Each time a shared_ptr is copied, this counter is incremented. Each time a shared_ptr is destructed, this counter is decremented. When this counter reaches 0, then the stored object is destroyed.

// simple example using the concept of setInterval

$(document).ready(function(){
var g = $('.jumping');
function blink(){
  g.animate({ 'left':'50px' 
  }).animate({
     'left':'20px'
        },1000)
}
setInterval(blink,1500);
});

Because, on whatever line the error is occurring at (you didn't tell us which that is), you're passing something to foreach that is not an array.

Look at what you're passing into foreach, determine what it is (with var_export), find out why it's not an array... and fix it.

Basic, basic debugging.

Here the async version.

public static Task<BitmapSource> ToBitmapSourceAsync(this Bitmap bitmap)
{
    return Task.Run(() =>
    {
        using (System.IO.MemoryStream memory = new System.IO.MemoryStream())
        {
            bitmap.Save(memory, ImageFormat.Png);
            memory.Position = 0;
            BitmapImage bitmapImage = new BitmapImage();
            bitmapImage.BeginInit();
            bitmapImage.StreamSource = memory;
            bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
            bitmapImage.EndInit();
            bitmapImage.Freeze();
            return bitmapImage as BitmapSource;
        }
    });

}

Try this:

$("div.subtab_left li.notebook a").click(function(e) {
    e.preventDefault();
});

If somebody will find that it's still not working under non-admin users:

Example error:

you need to set '--always-unzip' option for easy_install:

easy_install --always-unzip python-keystoneclient

It will unzip your egg files and will allow import to find em.

Here is a demo to illustrate the difference:

document.querySelectorAll("button")[0].addEventListener('click', e=>{
  e.stopPropagation();
  alert(1);
});
document.querySelectorAll("button")[1].addEventListener('click', e=>{
  e.stopImmediatePropagation();
  alert(1);
});
document.querySelectorAll("button")[0].addEventListener('click', e=>{
  alert(2);
});
document.querySelectorAll("button")[1].addEventListener('click', e=>{
  alert(2);
});

<div onclick="alert(3)">
   <button>1...2</button>
   <button>1</button>
</div>

Notice that you can attach multiple event handlers to an event on an element.

You have to specify what encoding the data is. Either in meta or in headers

header('Content-Type: text/plain; charset=utf-8');

Use Either Debug.WriteLine() or Trace.WriteLine(). If in release mode, only the latter will appear in the output window, in debug mode, both will.

i just place one image in " d drive-->Data-->IMG". The image name is x.jpg:

And on c# code type

ImageBrush myBrush = new ImageBrush();

myBrush.ImageSource = new BitmapImage(new Uri(BaseUriHelper.GetBaseUri(this), "D:\\Data\\IMG\\x.jpg"));

(please put double slash in between path)

this.Background = myBrush;

finally i got the background..

You just need one line:

ImageViewer1.Source = new BitmapImage(new Uri(@"\myserver\folder1\Customer Data\sample.png"));

My sugession is Foxit PDF Reader which is very helpful to do important text editing work on pdf file.

I had the same problem...

How to fix - add the following properties in to the pom.xml

<properties>
    <!--  compiler settings -->
    <maven.compiler.source>1.6</maven.compiler.source>
    <maven.compiler.target>1.6</maven.compiler.target>
</properties>        

It is because the Creation was delayed. If you want the picture to be loaded immediately, you can simply add this code into the init phase.

src.CacheOption = BitmapCacheOption.OnLoad;

like this:

src.BeginInit();
src.UriSource = new Uri("picture.jpg", UriKind.Relative);
src.CacheOption = BitmapCacheOption.OnLoad;
src.EndInit();

Try Stretch="UniformToFill" on the Image

The easiest thing is if you can make the WPF bitmap from a file directly.

Otherwise you will have to use System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap.

you may use

ImageSourceConverter class

to get what you want

    img1.Source = (ImageSource)new ImageSourceConverter().ConvertFromString("/Assets/check.png");

In my environment, I just added the two files to class path. And is work fine.

i had this same question a while back.. all types in ts are nullable, because void is a subtype of all types (unlike, for example, scala).

see if this flowchart helps - https://github.com/bcherny/language-types-comparison#typescript

A solution to this problem, without having to introduce complex functions and heavily modify the original one, is to store the value in a temporary file and read / write it when needed.

This approach helped me greatly when I had to mock a bash function called multiple times in a bats test case.

For example, you could have:

# Usage read_value path_to_tmp_file
function read_value {
  cat "${1}"
}

# Usage: set_value path_to_tmp_file the_value
function set_value {
  echo "${2}" > "${1}"
}
#----

# Original code:

function test1() {
  e=4
  set_value "${tmp_file}" "${e}"
  echo "hello"
}


# Create the temp file
# Note that tmp_file is available in test1 as well
tmp_file=$(mktemp)

# Your logic
e=2
# Store the value
set_value "${tmp_file}" "${e}"

# Run test1
test1

# Read the value modified by test1
e=$(read_value "${tmp_file}")
echo "$e"

The drawback is that you might need multiple temp files for different variables. And also you might need to issue a sync command to persist the contents on the disk between one write and read operations.

            case '3' : System.out.print("Enter Two Number : ");
                a = scan.nextFloat();
                b = scan.nextFloat();
                res = a * b;

                a = scan.nextFloat();
                b = scan.nextFloat();
                res = a / b;

        }
    }while(choice != 5);

You can achieve a unix compatible multiple file rename (using wildcards) by creating a for loop:

for file in *; do
  mv $file new.${file%%}
done

You can use Newtonsoft.Json just add Newtonsoft.dll to your project and use below script

using System;
using Newtonsoft.Json;
using UnityEngine;

public class NewBehaviourScript : MonoBehaviour
{

    [Serializable]
    public class Person
    {
        public string id;
        public string name;
    }
    public Person[] person;

    private void Start()
    {
       var myjson = JsonConvert.SerializeObject(person);

        print(myjson);

    }
}

another solution is using JsonHelper

using System;
using Newtonsoft.Json;
using UnityEngine;

public class NewBehaviourScript : MonoBehaviour
{

    [Serializable]
    public class Person
    {
        public string id;
        public string name;
    }
    public Person[] person;

    private void Start()
    {
        var myjson = JsonHelper.ToJson(person);

        print(myjson);

    }
}

Done by having it like that:

view = inflater.inflate(R.layout.entry_detail, container, false);
TextView tp1= (TextView) view.findViewById(R.id.tp1);
LinearLayout layone= (LinearLayout) view.findViewById(R.id.layone);
tp1.setVisibility(View.VISIBLE);
layone.setVisibility(View.VISIBLE);

There is collection of Func<...> classes - Func that is probably what you are looking for:

 void MyMethod(Func<int> param1 = null) 

This defines method that have parameter param1 with default value null (similar to AS), and a function that returns int. Unlike AS in C# you need to specify type of the function's arguments.

So if you AS usage was

MyMethod(function(intArg, stringArg) { return true; }) 

Than in C# it would require param1 to be of type Func<int, siring, bool> and usage like

MyMethod( (intArg, stringArg) => { return true;} ); 

try this formula in column E:

=IF( AND( ISNUMBER(D2), D2=G2), H2, "")

your error is the number test, ISNUMBER( ISMATCH(D2,G:G,0) )

you do check if ismatch is-a-number, (i.e. isNumber("true") or isNumber("false"), which is not!.

I hope you understand my explanation.

For Scalar Function Syntax is

Select dbo.Function_Name(parameter_name)

Select dbo.Department_Employee_Count('HR')

In some SQL databases, VARCHAR will be padded out to its maximum size in order to optimize the offsets, This is to speed up full table scans and indexes.

Because of this, you do not have any space savings by using a VARCHAR(200) compared to a CHAR(200)

Just wanted to contribute my version of objects comparison utilizing some es6 features. It doesn't take an order into account. After converting all if/else's to ternary I've came with following:

function areEqual(obj1, obj2) {

    return Object.keys(obj1).every(key => {

            return obj2.hasOwnProperty(key) ?
                typeof obj1[key] === 'object' ?
                    areEqual(obj1[key], obj2[key]) :
                obj1[key] === obj2[key] :
                false;

        }
    )
}

You can use this to replace the function if it doesn't exist:

<script>
if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function(elt /*, from*/) {
        var len = this.length >>> 0;

        var from = Number(arguments[1]) || 0;
        from = (from < 0) ? Math.ceil(from) : Math.floor(from);
        if (from < 0)
            from += len;

        for (; from < len; from++) {
            if (from in this && this[from] === elt)
                return from;
        }
        return -1;
    };
}
</script>

const duration = moment.duration(62, 'hours');
const n = 24 * 60 * 60 * 1000;
const days = Math.floor(duration / n);
const str = moment.utc(duration % n).format('H [h] mm [min] ss [s]');
console.log(`${days > 0 ? `${days} ${days == 1 ? 'day' : 'days'} ` : ''}${str}`);

Prints:

2 days 14 h 00 min 00 s

So, weirdly excel imports a csv date in different ways. And, displays them differently depending on the format used in the csv file. Unfortunately the ISO 8061 format comes in as a string. Which prevents you from possibly reformatting the date yourself.

All the ones the do come in as a date... contain the entire information... but they format differently... if you don't like it you can choose a new format for the column in excel and it will work. (Note: you can tell it came in as a valid date/time as it will right justify... if it comes in as a string it will left justify)

Here are formats I tested:

"yyyy-MM-dd" shows up as a date of course when opened in excel. (also "MM/dd/yyyy" works)

"yyyy-MM-dd HH:mm:ss" default display format is "MM/dd/yyyy HH:mm" (date and time w/out seconds)

"yyyy-MM-dd HH:mm:ss.fff" default display format is "HH:mm:ss" (time only w/ seconds)

use value instead of query (must specify index of node to return in the XQuery as well as passing the sql data type to return as the second parameter):

select
    xt.Id
    , x.m.value( '@id[1]', 'varchar(max)' ) MetricId
from
    XmlTest xt
    cross apply xt.XmlData.nodes( '/Sqm/Metrics/Metric' ) x(m)

I had the same problem and my problem had nothing to do with paths. One of my dll-s was written in c++ and it turnes out that if your visual studio doesn't know how to open a dll file it will say that it did not find it. What i did was locate which dll it did not find, than searched for that dll in my directories and opened it in a separate visual studio window. When trying to navigate through Solution explorer of that project, visual studio said that it cannot show what is inside and that i need some extra extensions, so that it can open those files. Surely enough, after installing the recomended extension (in my case something to do with c++) the

"This application has failed to start because xxx.dll was not found."

error miraculously dissapeared.

I need to point out here that you're incorrectly adding middleware to the application. The app.use calls should not be done within the app.get request handler, but outside of it. Simply call them directly after createServer, or take a look at the other examples in the docs.

The secret you pass to express.session should be a string constant, or perhaps something taken from a configuration file. Don't feed it something the client might know, that's actually dangerous. It's a secret only the server should know about.

If you want to store the email address in the session, simply do something along the lines of:

req.session.email = req.param('email');

With that out of the way...

If I understand correctly, what you're trying to do is handle one or more HTTP requests and keep track of a session, then later on open a Socket.IO connection from which you need the session data as well.

What's tricky about this problem is that Socket.IO's means of making the magic work on any http.Server is by hijacking the request event. Thus, Express' (or rather Connect's) session middleware is never called on the Socket.IO connection.

I believe you can make this work, though, with some trickery.

You can get to Connect's session data; you simply need to get a reference to the session store. The easiest way to do that is to create the store yourself before calling express.session:

// A MemoryStore is the default, but you probably want something
// more robust for production use.
var store = new express.session.MemoryStore;
app.use(express.session({ secret: 'whatever', store: store }));

Every session store has a get(sid, callback) method. The sid parameter, or session ID, is stored in a cookie on the client. The default name of that cookie is connect.sid. (But you can give it any name by specifying a key option in your express.session call.)

Then, you need to access that cookie on the Socket.IO connection. Unfortunately, Socket.IO doesn't seem to give you access to the http.ServerRequest. A simple work around would be to fetch the cookie in the browser, and send it over the Socket.IO connection.

Code on the server would then look something like the following:

var io      = require('socket.io'),
    express = require('express');

var app    = express.createServer(),
    socket = io.listen(app),
    store  = new express.session.MemoryStore;
app.use(express.cookieParser());
app.use(express.session({ secret: 'something', store: store }));

app.get('/', function(req, res) {
  var old = req.session.email;
  req.session.email = req.param('email');

  res.header('Content-Type', 'text/plain');
  res.send("Email was '" + old + "', now is '" + req.session.email + "'.");
});

socket.on('connection', function(client) {
  // We declare that the first message contains the SID.
  // This is where we handle the first message.
  client.once('message', function(sid) {
    store.get(sid, function(err, session) {
      if (err || !session) {
        // Do some error handling, bail.
        return;
      }

      // Any messages following are your chat messages.
      client.on('message', function(message) {
        if (message.email === session.email) {
          socket.broadcast(message.text);
        }
      });
    });
  });
});

app.listen(4000);

This assumes you only want to read an existing session. You cannot actually create or delete sessions, because Socket.IO connections may not have a HTTP response to send the Set-Cookie header in (think WebSockets).

If you want to edit sessions, that may work with some session stores. A CookieStore wouldn't work for example, because it also needs to send a Set-Cookie header, which it can't. But for other stores, you could try calling the set(sid, data, callback) method and see what happens.

setLoanItem() isn't a static method, it's an instance method, which means it belongs to a particular instance of that class rather than that class itself.

Essentially, you haven't specified what media object you want to call the method on, you've only specified the class name. There could be thousands of media objects and the compiler has no way of knowing what one you meant, so it generates an error accordingly.

You probably want to pass in a media object on which to call the method:

public void loanItem(Media m) {
    m.setLoanItem("Yes");
}

A couple of wires are crossed here. The various autoplay settings that you're working with only affect whether the SWF's root timeline starts out paused or not. So if your SWF had a timeline animation, or if it had an embedded video on the root timeline, then these settings would do what you're after.

However, the SWF you're working with almost certainly has only one frame on its timeline, so these settings won't affect playback at all. That one frame contains some flavor of video playback component, which contains ActionScript that controls how the video behaves. To get that player component to start of paused, you'll have to change the settings of the component itself.

Without knowing more about where the content came from it's hard to say more, but when one publishes from Flash, video player components normally include a parameter for whether to autoplay. If your SWF is being published by an application other than Flash (Captivate, I suppose, but I'm not up on that) then your best bet would be to check the settings for that app. Anyway it's not something you can control from the level of the HTML page. (Unless you were talking to the SWF from JavaScript, and for that to work the video component would have to be designed to allow it.)

I got the same problem and I just added the content of ~/.ssh/id_rsa.pub to my account in GitHub. After that just try again git push origin master, it should work.

You can also use the transform: scale("") option.

With jQuery:

jQuery('#myDivID').css("background-color");

With prototype:

$('myDivID').getStyle('backgroundColor'); 

With pure JS:

document.getElementById("myDivID").style.backgroundColor

It's 2020 and many of these answers no longer apply to the Sequelize v4/v5/v6 ecosystem.

The one good answer says to use sequelize-auto-migrations, but probably is not prescriptive enough to use in your project. So here's a bit more color...

Setup

My team uses a fork of sequelize-auto-migrations because the original repo is has not been merged a few critical PRs. #56 #57 #58 #59

$ yarn add github:scimonster/sequelize-auto-migrations#a063aa6535a3f580623581bf866cef2d609531ba

Edit package.json:

"scripts": {
  ...
  "db:makemigrations": "./node_modules/sequelize-auto-migrations/bin/makemigration.js",
  ...
}

Process

Note: Make sure you’re using git (or some source control) and database backups so that you can undo these changes if something goes really bad.

1. Delete all old migrations if any exist.
2. Turn off .sync()
3. Create a mega-migration that migrates everything in your current models (yarn db:makemigrations --name "mega-migration").
4. Commit your 01-mega-migration.js and the _current.json that is generated.
5. if you've previously run .sync() or hand-written migrations, you need to “Fake” that mega-migration by inserting the name of it into your SequelizeMeta table. INSERT INTO SequelizeMeta Values ('01-mega-migration.js').
6. Now you should be able to use this as normal…
7. Make changes to your models (add/remove columns, change constraints)
8. Run $ yarn db:makemigrations --name whatever
9. Commit your 02-whatever.js migration and the changes to _current.json, and _current.bak.json.
10. Run your migration through the normal sequelize-cli: $ yarn sequelize db:migrate.
11. Repeat 7-10 as necessary

Known Gotchas

1. Renaming a column will turn into a pair of removeColumn and addColumn. This will lose data in production. You will need to modify the up and down actions to use renameColumn instead.

For those who confused how to use renameColumn, the snippet would look like this. (switch "column_name_before" and "column_name_after" for the rollbackCommands)

{
    fn: "renameColumn",
    params: [
        "table_name",
        "column_name_before",
        "column_name_after",
        {
            transaction: transaction
        }
    ]
}

2. If you have a lot of migrations, the down action may not perfectly remove items in an order consistent way.

3. The maintainer of this library does not actively check it. So if it doesn't work for you out of the box, you will need to find a different community fork or another solution.

Although ctime isn't technically the time of creation, it quite often is.

Since ctime it isn't affected by changes to the contents of the file, it's usually only updated when the file is created. And yes - I can hear you all screaming - it's also updated if you change the access permissions or ownership... but generally that's something that's done once, usually at the same time you put the file there.

Personally I always use mtime for everything, and I imagine that is what you want. But anyway... here's a rehash of Guss's "unattractive" bash, in an easy to use function.

#!/bin/bash
function age() {
   local filename=$1
   local changed=`stat -c %Y "$filename"`
   local now=`date +%s`
   local elapsed

   let elapsed=now-changed
   echo $elapsed
}

file="/"
echo The age of $file is $(age "$file") seconds.

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

one more case where this issue can occur,

if(a==b)
double c;
getValue(c);

here, the value is declared in a condition and then used outside it.

There is a workaround by using the history API on modern browsers with fallback on old ones:

if(history.pushState) {
    history.pushState(null, null, '#myhash');
}
else {
    location.hash = '#myhash';
}

Do following steps

a) Change minSdkVersion and sync gradle

b) Revert back your minSdkVersion and sync gradle again

It will be resolved.

Firstly, double quote character is nothing special in regex - it's just another character, so it doesn't need escaping from the perspective of regex.

However, because java uses double quotes to delimit String constants, if you want to create a string in java with a double quote in it, you must escape them.

This code will test if your String matches:

if (str.matches("\".*\"")) {
    // this string starts and end with a double quote
}

Note that you don't need to add start and end of input markers (^ and $) in the regex, because matches() requires that the whole input be matched to return true - ^ and $ are implied.

use default convertation class: Convert.ToDecimal(Double)

Downgrading the JRE from 7 to 6 fixed this issue for me.

compiler changes checks your source code for errors and changes it into object code.this is the code that operating system runs.

You often don't write a whole program in single file so linker links all your object code files.

your program wont get executed unless it is in main memory

In case you are using PyCharm and project stops working after rename:

1. Edit Run/Debug configuration and change environment variable DJANGO_SETTINGS_MODULE, since it includes your project name.
2. Go to Settings / Languages & Frameworks / Django and update the settings file location.

From long to DateTime: new DateTime(long ticks)

From DateTime to long: DateTime.Ticks

I ran into this error message on 2 separate occasions, with lazy loading in Angular 7 and the above did not help. For both of the below to work you MUST stop and restart ng serve for it to completely update correctly.

1) First time I had somehow incorrectly imported my AppModule into the lazy loaded feature module. I removed this import from the lazy loaded module and it started working again.

2) Second time I had a separate CoreModule that I was importing into the AppModule AND same lazy loaded module as #1. I removed this import from the lazy loaded module and it started working again.

Basically, check your hierarchy of imports and pay close attention to the order of the imports (if they are imported where they should be). Lazy loaded modules only need their own route component / dependencies. App and parent dependencies will be passed down whether they are imported into AppModule, or imported from another feature module that is NOT-lazy loaded and already imported in a parent module.

e.currentTarget would always return the component onto which the event listener is added.

On the other hand, e.target can be the component itself or any direct child or grand child or grand-grand-child and so on who received the event. In other words, e.target returns the component which is on top in the Display List hierarchy and must be in the child hierarchy or the component itself.

One use can be when you have several Image in Canvas and you want to drag Images inside the component but Canvas. You can add a listener on Canvas and in that listener you can write the following code to make sure that Canvas wouldn't get dragged.

function dragImageOnly(e:MouseEvent):void
{
    if(e.target==e.currentTarget)
    {
        return;
     }
     else
     {
        Image(e.target).startDrag();
     }
}

Really the answer to this question depends on what operating system and programming language you are using. There is no "ASCII code" per se. The operating system detects you hit an arrow key and triggers an event that programs can capture. For example, on modern Windows machines, you would get a WM_KEYUP or WM_KEYDOWN event. It passes a 16-bit value usually to determine which key was pushed.

lxml is recent, updated, and includes a pretty print function

import lxml.etree as etree

x = etree.parse("filename")
print etree.tostring(x, pretty_print=True)

Check out the lxml tutorial: http://lxml.de/tutorial.html

See http://wiki.apache.org/httpd/DistrosDefaultLayout for discussion of where you might find Apache httpd configuration files on various platforms, since this can vary from release to release and platform to platform. The most common answer, however, is either /etc/apache/conf or /etc/httpd/conf

Generically, you can determine the answer by running the command:

httpd -V

(That's a capital V). Or, on systems where httpd is renamed, perhaps apache2ctl -V

This will return various details about how httpd is built and configured, including the default location of the main configuration file.

One of the lines of output should look like:

-D SERVER_CONFIG_FILE="conf/httpd.conf"

which, combined with the line:

-D HTTPD_ROOT="/etc/httpd"

will give you a full path to the default location of the configuration file

You could do this with some simple css. From what I read, you want to set the Height of the element with the class "select2-choices".

.select2-choices {
  min-height: 150px;
  max-height: 150px;
  overflow-y: auto;
}

That should give you a set height of 150px and it will scroll if needed. Simply adjust the height till your image fits as desired.

You can also use css to set the height of the select2-results (the drop down portion of the select control).

ul.select2-results {
 max-height: 200px;
}

200px is the default height, so change it for the desired height of the drop down.

.success { background-color: #cffccc; overflow: scroll; min-width: 100%; }

You can try scroll or auto.

Just select the order yourself by typing in the column names. Note the double brackets:

frame = frame[['column I want first', 'column I want second'...etc.]]

I like to use....

echo "
1
2
3 " | sed -e 's,$, + p,g' | dc 

they will show the sum of each line...

applying over this situation:

ls -ld $(< file.txt) | awk '{print $5}' | sed -e 's,$, + p,g' | dc 

Total is the last value...

Several things here.

First off, you're defining your CSS in 3 places!

In line, in the head and externally. I suggest you only choose one. I'm going to suggest externally.

I suggest you update your code in your ASP form from

<td style="background-color: #A3A3A3; color: #FFFFFF; font-family: 'Arial Black'; font-size: large; font-weight: bold;" 
        class="style6">

to this:

<td  class="style6">

And then update your css too

.style6
    {

I had the same problem too. Then i realized that in the MainPageServlet the urlPatterns parameter in @WebServlet annotation contained "/", because i wanted to forward to the MainPage if the user entered the section www.site.com/ . When i tried to open the css file from the browser, the url was www.site.com/css/desktop.css, but the page content was THE PAGE MainPage.jsp. So, i removed the "/" urlPattern and now i can use CSS files in my jsp file using one of the most common solutions (${pageContext.request.contextPath}/css/desktop.css). Make sure your servlet doesn't contain the "/" urlPattern. I hope this worked for u too, - Axel Montini

Django versions 1.8 and later:

You should use get_fields():

[f.name for f in MyModel._meta.get_fields()]

The get_all_field_names() method is deprecated starting from Django 1.8 and will be removed in 1.10.

The documentation page linked above provides a fully backwards-compatible implementation of get_all_field_names(), but for most purposes the previous example should work just fine.

Django versions before 1.8:

model._meta.get_all_field_names()

That should do the trick.

That requires an actual model instance. If all you have is a subclass of django.db.models.Model, then you should call myproject.myapp.models.MyModel._meta.get_all_field_names()

When using google gson library.

var getRowData =
[{
    "dayOfWeek": "Sun",
    "date": "11-Mar-2012",
    "los": "1",
    "specialEvent": "",
    "lrv": "0"
},
{
    "dayOfWeek": "Mon",
    "date": "",
    "los": "2",
    "specialEvent": "",
    "lrv": "0.16"
}];

    JsonElement root = new JsonParser().parse(request.getParameter("getRowData"));
     JsonArray  jsonArray = root.getAsJsonArray();
     JsonObject  jsonObject1 = jsonArray.get(0).getAsJsonObject();
     String dayOfWeek = jsonObject1.get("dayOfWeek").toString();

// when using jackson library

    JsonFactory f = new JsonFactory();
              ObjectMapper mapper = new ObjectMapper();
          JsonParser jp = f.createJsonParser(getRowData);
          // advance stream to START_ARRAY first:
          jp.nextToken();
          // and then each time, advance to opening START_OBJECT
         while (jp.nextToken() == JsonToken.START_OBJECT) {
            Map<String,Object> userData = mapper.readValue(jp, Map.class);
            userData.get("dayOfWeek");
            // process
           // after binding, stream points to closing END_OBJECT
        }

You can instruct the child process to print its environment variables (by calling "env"), then loop over the printed environment variables in the parent process and call "export" on those variables.

The following code is based on Capturing output of find . -print0 into a bash array

If the parent shell is the bash, you can use

while IFS= read -r -d $'\0' line; do
    export "$line"
done < <(bash -s <<< 'export VARNAME=something; env -0')
echo $VARNAME

If the parent shell is the dash, then read does not provide the -d flag and the code gets more complicated

TMPDIR=$(mktemp -d)
mkfifo $TMPDIR/fifo
(bash -s << "EOF"
    export VARNAME=something
    while IFS= read -r -d $'\0' line; do
        echo $(printf '%q' "$line")
    done < <(env -0)
EOF
) > $TMPDIR/fifo &
while read -r line; do export "$(eval echo $line)"; done < $TMPDIR/fifo
rm -r $TMPDIR
echo $VARNAME

1 - disable fork option in /etc/mongodb.conf if enabled

2 - Repair your database

mongod --repair --dbpath DBPATH

3 - kill current mongod process

Find mongo processes

ps -ef | grep mongo

you'll get mongod PID

mongodb   PID     1  0 06:26 ?        00:00:00 /usr/bin/mongod --config /etc/mongodb.conf

Stop current mongod process

kill -9 PID

4 - start mongoDB service

service mongodb start

If you're writing a Java Applet, you can override the Applet "destroy()" method. It is...

 * Called by the browser or applet viewer to inform
 * this applet that it is being reclaimed and that it should destroy
 * any resources that it has allocated. The stop() method
 * will always be called before destroy().

Obviously not what you want, but might be what other people are looking for.

You can use the default traceroute command for this purpose, then there will be nothing to install.

traceroute -T -p 9100 <IP address/hostname>

The -T argument is required so that the TCP protocol is used instead of UDP.

In the rare case when traceroute isn't available, you can also use ncat.

nc -Czvw 5 <IP address/hostname> 9100

Back in the good ole days, there were just two types of languages: compiled and interpreted.

Compiled languages utilized a "compiler" to read the language syntax and convert it into identical assembly language code, which could than just directly on the CPU. Interpreted languages used a couple of different schemes, but essentially the language syntax was converted into an intermediate form, and then run in a "interpreter", an environment for executing the code.

Thus, in a sense, there was another "layer" -- the interpreter -- between the code and the machine. And, as always the case in a computer, more means more resources get used. Interpreters were slower, because they had to perform more operations.

More recently, we've seen more hybrid languages like Java, that employ both a compiler and an interpreter to make them work. It's complicated, but a JVM is faster, more sophisticated and way more optimized than the old interpreters, so it stands a much better change of performing (over time) closer to just straight compiled code. Of course, the newer compilers also have more fancy optimizing tricks so they tend to generate way better code than they used to as well. But most optimizations, most often (although not always) make some type of trade-off such that they are not always faster in all circumstances. Like everything else, nothing comes for free, so the optimizers must get their boast from somewhere (although often times it using compile-time CPU to save runtime CPU).

Getting back to C, it is a simple language, that can be compiled into fairly optimized assembly and then run directly on the target machine. In C, if you increment an integer, it's more than likely that it is only one assembler step in the CPU, in Java however, it could end up being a lot more than that (and could include a bit of garbage collection as well :-) C offers you an abstraction that is way closer to the machine (assembler is the closest), but you end up having to do way more work to get it going and it is not as protected, easy to use or error friendly. Most other languages give you a higher abstraction and take care of more of the underlying details for you, but in exchange for their advanced functionality they require more resources to run. As you generalize some solutions, you have to handle a broader range of computing, which often requires more resources.

Same as accepted answer, But note that it works even with .crt file and not just .pem file, just in case if you are not able to find .pem file location.

Have you thought about using Python list's .index(value) method? It return the index in the list of where the first instance of the value passed in is found.

No because this fundamentally means that you will not be grouping anything. If you group by all columns (and have a properly defined table w/ a unique index) then SELECT * FROM table is essentially the same thing as SELECT * FROM table GROUP BY *.

When figuring out if an url exists from php there are a few things to pay attention to:

• Is the url itself valid (a string, not empty, good syntax), this is quick to check server side.
• Waiting for a response might take time and block code execution.
• Not all headers returned by get_headers() are well formed.
• Use curl (if you can).
• Prevent fetching the entire body/content, but only request the headers.
• Consider redirecting urls:
• Do you want the first code returned?
• Or follow all redirects and return the last code?
• You might end up with a 200, but it could redirect using meta tags or javascript. Figuring out what happens after is tough.

Keep in mind that whatever method you use, it takes time to wait for a response.
All code might (and probably will) halt untill you either know the result or the requests have timed out.

For example: the code below could take a LONG time to display the page if the urls are invalid or unreachable:

<?php
$urls = getUrls(); // some function getting say 10 or more external links

foreach($urls as $k=>$url){
  // this could potentially take 0-30 seconds each
  // (more or less depending on connection, target site, timeout settings...)
  if( ! isValidUrl($url) ){
    unset($urls[$k]);
  }
}

echo "yay all done! now show my site";
foreach($urls as $url){
  echo "<a href=\"{$url}\">{$url}</a><br/>";
}

The functions below could be helpfull, you probably want to modify them to suit your needs:

    function isValidUrl($url){
        // first do some quick sanity checks:
        if(!$url || !is_string($url)){
            return false;
        }
        // quick check url is roughly a valid http request: ( http://blah/... ) 
        if( ! preg_match('/^http(s)?:\/\/[a-z0-9-]+(\.[a-z0-9-]+)*(:[0-9]+)?(\/.*)?$/i', $url) ){
            return false;
        }
        // the next bit could be slow:
        if(getHttpResponseCode_using_curl($url) != 200){
//      if(getHttpResponseCode_using_getheaders($url) != 200){  // use this one if you cant use curl
            return false;
        }
        // all good!
        return true;
    }
    
    function getHttpResponseCode_using_curl($url, $followredirects = true){
        // returns int responsecode, or false (if url does not exist or connection timeout occurs)
        // NOTE: could potentially take up to 0-30 seconds , blocking further code execution (more or less depending on connection, target site, and local timeout settings))
        // if $followredirects == false: return the FIRST known httpcode (ignore redirects)
        // if $followredirects == true : return the LAST  known httpcode (when redirected)
        if(! $url || ! is_string($url)){
            return false;
        }
        $ch = @curl_init($url);
        if($ch === false){
            return false;
        }
        @curl_setopt($ch, CURLOPT_HEADER         ,true);    // we want headers
        @curl_setopt($ch, CURLOPT_NOBODY         ,true);    // dont need body
        @curl_setopt($ch, CURLOPT_RETURNTRANSFER ,true);    // catch output (do NOT print!)

            @curl_setopt($ch, CURLOPT_FOLLOWLOCATION ,true);
            @curl_setopt($ch, CURLOPT_MAXREDIRS      ,10);  // fairly random number, but could prevent unwanted endless redirects with followlocation=true
        }else{
            @curl_setopt($ch, CURLOPT_FOLLOWLOCATION ,false);
        }
//      @curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,5);   // fairly random number (seconds)... but could prevent waiting forever to get a result
//      @curl_setopt($ch, CURLOPT_TIMEOUT        ,6);   // fairly random number (seconds)... but could prevent waiting forever to get a result
//      @curl_setopt($ch, CURLOPT_USERAGENT      ,"Mozilla/5.0 (Windows NT 6.0) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1");   // pretend we're a regular browser
        @curl_exec($ch);
        if(@curl_errno($ch)){   // should be 0
            @curl_close($ch);
            return false;
        }
        $code = @curl_getinfo($ch, CURLINFO_HTTP_CODE); // note: php.net documentation shows this returns a string, but really it returns an int
        @curl_close($ch);
        return $code;
    }
    
    function getHttpResponseCode_using_getheaders($url, $followredirects = true){
        // returns string responsecode, or false if no responsecode found in headers (or url does not exist)
        // NOTE: could potentially take up to 0-30 seconds , blocking further code execution (more or less depending on connection, target site, and local timeout settings))
        // if $followredirects == false: return the FIRST known httpcode (ignore redirects)

        if(! $url || ! is_string($url)){
            return false;
        }
        $headers = @get_headers($url);
        if($headers && is_array($headers)){
            if($followredirects){
                // we want the last errorcode, reverse array so we start at the end:
                $headers = array_reverse($headers);
            }
            foreach($headers as $hline){
                // search for things like "HTTP/1.1 200 OK" , "HTTP/1.0 200 OK" , "HTTP/1.1 301 PERMANENTLY MOVED" , "HTTP/1.1 400 Not Found" , etc.
                // note that the exact syntax/version/output differs, so there is some string magic involved here
                if(preg_match('/^HTTP\/\S+\s+([1-9][0-9][0-9])\s+.*/', $hline, $matches) ){// "HTTP/*** ### ***"
                    $code = $matches[1];
                    return $code;
                }
            }
            // no HTTP/xxx found in headers:
            return false;
        }
        // no headers :
        return false;
    }

More generally, all of the following are valid syntactically:

if condition:
    do_something()


if condition: do_something()

if condition:
    do_something()
    do_something_else()

if condition: do_something(); do_something_else()

...etc.

Here are the two main approaches. I prefer this one for its readability:

bar <- subset(foo, location == "there")

Note that you can string together many conditionals with & and | to create complex subsets.

The second is the indexing approach. You can index rows in R with either numeric, or boolean slices. foo$location == "there" returns a vector of T and F values that is the same length as the rows of foo. You can do this to return only rows where the condition returns true.

foo[foo$location == "there", ]

The idea is to have equal size of message being sent from Kafka Producer to Kafka Broker and then received by Kafka Consumer i.e.

Kafka producer --> Kafka Broker --> Kafka Consumer

Suppose if the requirement is to send 15MB of message, then the Producer, the Broker and the Consumer, all three, needs to be in sync.

Kafka Producer sends 15 MB --> Kafka Broker Allows/Stores 15 MB --> Kafka Consumer receives 15 MB

The setting therefore should be:

a) on Broker:

message.max.bytes=15728640 
replica.fetch.max.bytes=15728640

b) on Consumer:

fetch.message.max.bytes=15728640

What you're after is the ID3 module. It's very simple and will give you exactly what you need. Just copy the ID3.py file into your site-packages directory and you'll be able to do something like the following:

from ID3 import *
try:
  id3info = ID3('file.mp3')
  print id3info
  # Change the tags
  id3info['TITLE'] = "Green Eggs and Ham"
  id3info['ARTIST'] = "Dr. Seuss"
  for k, v in id3info.items():
    print k, ":", v
except InvalidTagError, message:
  print "Invalid ID3 tag:", message

if you want to populate contents of your partial view inside your view you can use

@Html.Partial("PartialViewName")

or

{@Html.RenderPartial("PartialViewName");}

if you want to make server request and process the data and then return partial view to you main view filled with that data you can use

...
    @Html.Action("Load", "Home")
...

public PartialViewResult Load()
{
    return PartialView("_LoadView");
}

if you want user to click on the link and then populate the data of partial view you can use:

@Ajax.ActionLink(
    "Click Here to Load the Partial View", 
    "ActionName", 
    "ControlerName",
    null, 
    new AjaxOptions { UpdateTargetId = "toUpdate" }
)

C#

    public class ValidateModelAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(HttpActionContext actionContext)
        {
            if (actionContext.ModelState.IsValid == false)
            {
                actionContext.Response = actionContext.Request.CreateErrorResponse(
                    HttpStatusCode.BadRequest, actionContext.ModelState);
            }
        }
    }

...

    [ValidateModel]
    public HttpResponseMessage Post([FromBody]AnyModel model)
    {

Javascript

$.ajax({
        type: "POST",
        url: "/api/xxxxx",
        async: 'false',
        contentType: "application/json; charset=utf-8",
        data: JSON.stringify(data),
        error: function (xhr, status, err) {
            if (xhr.status == 400) {
                DisplayModelStateErrors(xhr.responseJSON.ModelState);
            }
        },
....


function DisplayModelStateErrors(modelState) {
    var message = "";
    var propStrings = Object.keys(modelState);

    $.each(propStrings, function (i, propString) {
        var propErrors = modelState[propString];
        $.each(propErrors, function (j, propError) {
            message += propError;
        });
        message += "\n";
    });

    alert(message);
};

The usual cause of this is that you're also using Prototype, MooTools, or some other library that makes use of the $ symbol, and you're including that library after jQuery, and so that library is "winning" (taking $ for itself). So the return value of $ isn't a jQuery instance, and so it doesn't have jQuery methods on it (like on).

You can use jQuery with those other libraries, but if you do, you have to use the jQuery symbol rather than its alias $, e.g.:

jQuery('body').on(...);

And it's usually best if you add this immediately after your script tag including jQuery, before the one including the other library:

<script>jQuery.noConflict();</script>

...although it's not required if you load the other library after jQuery (it is if you load the other library first).

Using multiple full-function DOM manipulation libraries on the same page isn't ideal, though, just in terms of page weight. So if you can stick with just Prototype/MooTools/whatever or just jQuery, that's usually better.

You should just include header file(s).

If you include header file, header file automatically finds .cpp file. --> This process is done by LINKER.

with this code, the id will not appear on the link

    document.querySelectorAll('a[href^="#"]').forEach(anchor => {
        anchor.addEventListener('click', function (e) {
            e.preventDefault();

            document.querySelector(this.getAttribute('href')).scrollIntoView({
                behavior: 'smooth'
            });
        });
    });

Use this....

string popupScript = "<script language=JavaScript>";
popupScript += "alert('Please enter valid Email Id');";
popupScript += "</";
popupScript += "script>";
Page.RegisterStartupScript("PopupScript", popupScript);

If you have even the relative pathname (in this case it appears to be ./) you can open files relative to your script file(s). I use Perl, but the same general solution can apply: I split the directory into an array of folders, then pop off the last element (the script), then push (or for you, append) on whatever I want, and then join them together again, and BAM! I have a working pathname that points to exactly where I expect it to point, relative or absolute.

Of course, there are better solutions, as posted. I just kind of like mine.

If you're using JQuery you can do:

$('#elementid').click();

At the risk of sounding obvious, always check the spelling of your forward class files. Sometimes XCode (at least XCode 4.3.2) will turn a declaration green that's actually camel cased incorrectly. Like in this example:

"_OBJC_CLASS_$_RadioKit", referenced from:
  objc-class-ref in RadioPlayerViewController.o

If RadioKit was a class file and you make it a property of another file, in the interface declaration, you might see that

Radiokit *rk;

has "Radiokit" in green when the actual decalaration should be:

RadioKit *rk;

This error will also throw this type of error. Another example (in my case), is when you have _iPhone and _iphone extensions on your class names for universal apps. Once I changed the appropriate file from _iphone to the correct _iPhone, the errors went away.

200,300, 400, 500 are all very generic. If you want generic, 400 is OK.

422 is used by an increasing number of APIs, and is even used by Rails out of the box.

No matter which status code you pick for your API, someone will disagree. But I prefer 422 because I think of '400 + text status' as too generic. Also, you aren't taking advantage of a JSON-ready parser; in contrast, a 422 with a JSON response is very explicit, and a great deal of error information can be conveyed.

Speaking of JSON response, I tend to standardize on the Rails error response for this case, which is:

{
    "errors" :
    { 
        "arg1" : ["error msg 1", "error msg 2", ...]
        "arg2" : ["error msg 1", "error msg 2", ...]
    }
}

This format is perfect for form validation, which I consider the most complex case to support in terms of 'error reporting richness'. If your error structure is this, it will likely handle all your error reporting needs.

I suggest to modify pdf.js: remove the download button, convert pdf (at backend part) to some intermediate format of pdf.js and put watermark also at server side.

In your Eclipse installation directory you should be able to find the file eclipse.ini. Open it and find the -vmargs section. Adjust the value of:

-Xmx1024m

In this example it is set to 1GB.

I asume you have connected to your database already.

$sql = "SELECT * FROM my_table";
$result = mysql_query($sql);

$row = 1; // 1-based index
while($row_data = mysql_fetch_assoc($result)) {
    $col = 0;
    foreach($row_data as $key=>$value) {
        $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
        $col++;
    }
    $row++;
}

As others have already mentioned, running PHP as a daemon is quite easy, and can be done using a single line of command. But the actual problem is keeping it running and managing it. I've had the same problem quite some time ago and although there are plenty of solutions already available, most of them have lots of dependencies or are difficult to use and not suitable for basic usages. I wrote a shell script that can manage a any process/application including PHP cli scripts. It can be set as a cronjob to start the application and will contain the application and manage it. If it's executed again, for example via the same cronjob, it check if the app is running or not, if it does then simply exits and let its previous instance continue managing the application.

I uploaded it to github, feel free to use it : https://github.com/sinasalek/EasyDeamonizer

EasyDeamonizer

Simply watches over your application (start, restart, log, monitor, etc). a generic script to make sure that your appliation remains running properly. Intentionally it uses process name instread of pid/lock file to prevent all its side effects and keep the script as simple and as stirghforward as possible, so it always works even when EasyDaemonizer itself is restarted. Features

• Starts the application and optionally a customized delay for each start
• Makes sure that only one instance is running
• Monitors CPU usage and restarts the app automatically when it reaches the defined threshold
• Setting EasyDeamonizer to run via cron to run it again if it's halted for any reason
• Logs its activity

At the risk of getting yet another mysterious down-vote...the fact that many mention the stack and memory with respect to value types and primitive types is because they must fit into a register in the microprocessor. You cannot push or pop something to/from the stack if it takes more bits than a register has....the instructions are, for example "pop eax" -- because eax is 32 bits wide on a 32-bit system.

Floating-point primitive types are handled by the FPU, which is 80 bits wide.

This was all decided long before there was an OOP language to obfuscate the definition of primitive type and I assume that value type is a term that has been created specifically for OOP languages.

filter expects to get a function and something that it can iterate over. The function should return True or False for each element in the iterable. In your particular example, what you're looking to do is something like the following:

In [47]: def greetings(x):
   ....:     return x == "hello"
   ....:

In [48]: filter(greetings, ["hello", "goodbye"])
Out[48]: ['hello']

Note that in Python 3, it may be necessary to use list(filter(greetings, ["hello", "goodbye"])) to get this same result.

Properties props = new Properties();
URL resource = getClass().getClassLoader().getResource("data.properties");         
props.load(new InputStreamReader(resource.openStream(), "UTF8"));

Works like a charm

:-)

You can look at phpinfo() or check if any of the functions of memcache is available. Ultimately, check whether the Memcache class exists or not.

e.g.

if(class_exists('Memcache')){
  // Memcache is enabled.
}

Just add position: fixed; in your div style.

I have checked and Its working fine in my code.

It's not print that does the formatting, It's a property of strings, so you can just use

newstring = "%.9f" % numvar

If you want to split/cut the array on an index i,

arr = arr.drop(i)

> arr = [1,2,3,4,5]
 => [1, 2, 3, 4, 5] 
> arr.drop(2)
 => [3, 4, 5] 

You mention you are using Pandas (in your title). If so, there is no need to use an external library, you can just use to_datetime

>>> pandas.to_datetime('today').normalize()
Timestamp('2015-10-14 00:00:00')

This will always return today's date at midnight, irrespective of the actual time, and can be directly used in pandas to do comparisons etc. Pandas always includes 00:00:00 in its datetimes.

Replacing today with now would give you the date in UTC instead of local time; note that in neither case is the tzinfo (timezone) added.

In pandas versions prior to 0.23.x, normalize may not have been necessary to remove the non-midnight timestamp.

You could use CSS to do that, but it wouldn't be supported in IE8-. You can use some site like http://borderradius.com to come up with actual CSS you'd use, which would look something like this (again, depending on how many browsers you're trying to support):

-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;

You can also wrap the output of a cmdlet (or pipeline) in @() to ensure that what you get back is an array rather than a single item.

For instance, dir usually returns a list, but depending on the options, it might return a single object. If you are planning on iterating through the results with a foreach-object, you need to make sure you get a list back. Here's a contrived example:

$results = @( dir c:\autoexec.bat)

One more thing... an empty array (like to initialize a variable) is denoted @().

The best answer here:

https://www.git-tower.com/learn/git/glossary/origin

In Git, "origin" is a shorthand name for the remote repository that a project was originally cloned from. More precisely, it is used instead of that original repository's URL - and thereby makes referencing much easier.

For Rails 4 you can put the following in an environment file:

# /config/environments/development.rb

config.active_record.logger = nil

As no one has mentioned - I would suggest to use great tool for such purpose - swaks

# yum info swaks

I have been using swaks to send email notifications from nagios via gmail for last 5 years without any problem.

EDIT (April 2014): This is a question/answer page that still gets a lot of hits it seems. I know I'm always getting upvotes for this post. But if you're reading this, you need to realize the answers posted here (both mine and the accepted answer) are out of date. If you want to implement efficient blur today, you should use RenderScript instead of the NDK or Java. RenderScript runs on Android 2.2+ (using the Android Support Library), so there's no reason not to use it.

The old answer follows, but beware as it's outdated.

For future² Googlers, here is an algorithm that I ported from Yahel's port of Quasimondo's algorithm, but using the NDK. It's based on Yahel's answer, of course. But this is running native C code, so it's faster. Much faster. Like, 40 times faster.

I find that using the NDK is how all image manipulation should be done on Android... it's somewhat annoying to implement at first (read a great tutorial on using JNI and the NDK here), but much better, and near real time for a lot of things.

For reference, using Yahel's Java function, it took 10 seconds to blur my 480x532 pixels image with a blur radius of 10. But it took 250ms using the native C version. And I'm pretty sure it can still be further optimized... I just did a dumb conversion of the java code, there's probably some manipulations that can be shortened, didn't want to spend too much time refactoring the whole thing.

    AndroidBitmap_unlockPixels(env, bitmapOut);

    LOGI ("Bitmap blurred.");
}

int min(int a, int b) {
    return a > b ? b : a;
}

int max(int a, int b) {
    return a > b ? a : b;
}

Then use it like this (considering a class called com.insert.your.package.ClassName and a native function called functionToBlur, as the code above states):

// Create a copy
Bitmap bitmapOut = bitmapIn.copy(Bitmap.Config.ARGB_8888, true);
// Blur the copy
functionToBlur(bitmapIn, bitmapOut, __radius);

It expects a RGB_8888 bitmap!

To use a RGB_565 bitmap, either create a converted copy before passing the parameter (yuck), or change the function to use a new rgb565 type instead of rgba:

typedef struct {
    uint16_t byte0;
} rgb565;

The problem is that if you do that you can't read .red, .green and .blue of the pixel anymore, you need to read the byte properly, duh. When I needed that before, I did this:

r = (pixels[x].byte0 & 0xF800) >> 8;
g = (pixels[x].byte0 & 0x07E0) >> 3;
b = (pixels[x].byte0 & 0x001F) << 3;

But there's probably some less dumb way of doing it. I'm not much of a low-level C coder, I'm afraid.

with pretty-print format:

import json

with open(path_to_file, 'w') as file:
    json_string = json.dumps(sample, default=lambda o: o.__dict__, sort_keys=True, indent=2)
    file.write(json_string)

This should fulfill your requirements.

The accepted answer has a couple of shortcomings:

• Don't target IDs in your JavaScript code. Use classes and data attributes to avoid repeating your code.
• It is good practice to hide with CSS on load rather than with JavaScript—to support non-JavaScript users, and prevent a show-hide flicker on load.

Considering the above, your options could even have different values, but toggle the same class:

<select class="div-toggle" data-target=".my-info-1">
  <option value="orange" data-show=".citrus">Orange</option>
  <option value="lemon" data-show=".citrus">Lemon</option>
  <option value="apple" data-show=".pome">Apple</option>
  <option value="pear" data-show=".pome">Pear</option>
</select>

<div class="my-info-1">
  <div class="citrus hide">Citrus is...</div>
  <div class="pome hide">A pome is...</div>
</div>

jQuery:

$(document).on('change', '.div-toggle', function() {
  var target = $(this).data('target');
  var show = $("option:selected", this).data('show');
  $(target).children().addClass('hide');
  $(show).removeClass('hide');
});
$(document).ready(function(){
    $('.div-toggle').trigger('change');
});

CSS:

.hide {
  display: none;
}

Here's a JSFiddle to see it in action.

To answer your question directly:

The single most important difference between the two is that you should start using JupyterLab straight away, and that you should not worry about Jupyter Notebook at all. Because:

JupyterLab will eventually replace the classic Jupyter Notebook. Throughout this transition, the same notebook document format will be supported by both the classic Notebook and JupyterLab

But you would also like to also know this:

Other posts have suggested that Jupyter Notebook (JN) could potentially be easier to use than JupyterLab (JL) for beginners. But I would have to disagree.

A great advantage with JL, and arguably one of the most important differences between JL and JN, is that you can more easily run a single line and even highlighted text. I prefer using a keyboard shortcut for this, and assigning shortcuts is pretty straight-forward.

And the fact that you can execute code in a Python console makes JL much more fun to work with. Other answers have already mentioned this, but JL can in some ways be considered a tool to run Notebooks and more. So the way I use JupyterLab is by having it set up with an .ipynb file, a file browser and a python console like this:

And now you have these tools at your disposal:

1. View Files, running kernels, Commands, Notebook Tools, Open Tabs or Extension manager
2. Run cells using, among other options, Ctrl+Enter
3. Run single expression, line or highlighted text using menu options or keyboard shortcuts
4. Run code directly in a console using Shift+Enter
5. Inspect variables, dataframes or plots quickly and easily in a console without cluttering your notebook output.

Building on the previous answers (pun intended), an excellent real-world example is Groovy's built in support for Builders.

• Creating XML using Groovy's MarkupBuilder
• Creating XML using Groovy's StreamingMarkupBuilder
• Swing Builder
• SwingXBuilder

See Builders in the Groovy Documentation

For ASP.NET, the Load User Profile setting needs to be set on the app pool but that's not enough. There is a hidden setting named setProfileEnvironment in \Windows\System32\inetsrv\Config\applicationHost.config, which for some reason is turned off by default, instead of on as described in the documentation. You can either change the default or set it on your app pool. All the methods on the Environment class will then return proper values.

The basic problem here is that building and linking a C++ program depends heavily on the build system in use. You will need to support the following distinct tasks, using some combination of plugins and custom code:

1. General C++ language support for the editor. This is usually done using ms-vscode.cpptools, which most people expect to also handle a lot of other stuff, like build support. Let me save you some time: it doesn't. However, you will probably want it anyway.

2. Build, clean, and rebuild tasks. This is where your choice of build system becomes a huge deal. You will find plugins for things like CMake and Autoconf (god help you), but if you're using something like Meson and Ninja, you are going to have to write some helper scripts, and configure a custom "tasks.json" file to handle these. Microsoft has totally changed everything about that file over the last few versions, right down to what it is supposed to be called and the places (yes, placeS) it can go, to say nothing of completely changing the format. Worse, they've SORT OF kept backward compatibility, to be sure to use the "version" key to specify which variant you want. See details here:

https://code.visualstudio.com/docs/editor/tasks

...but note conflicts with:

https://code.visualstudio.com/docs/languages/cpp

WARNING: IN ALL OF THE ANSWERS BELOW, ANYTHING THAT BEGINS WITH A "VERSION" TAG BELOW 2.0.0 IS OBSOLETE.

Here's the closest thing I've got at the moment. Note that I kick most of the heavy lifting off to scripts, this doesn't really give me any menu entries I can live with, and there isn't any good way to select between debug and release without just making another three explicit entries in here. With all that said, here is what I can tolerate as my .vscode/tasks.json file at the moment:

Note that, in theory, this file is supposed to work if you put it in the workspace root, so that you aren't stuck checking files in hidden directories (.vscode) into your revision control system. I have yet to see that actually work; test it, but if it fails, put it in .vscode. Either way, the IDE will bitch if it isn't there anyway. (Yes, at the moment, this means I have been forced to check .vscode into subversion, which I'm not happy about.) Note that my build scripts (not shown) simply create (or recreate) a DEBUG directory using, in my case, meson, and build inside it (using, in my case, ninja).

3. Run, debug, attach, halt. These are another set of tasks, defined in "launch.json". Or at least they used to be. Microsoft has made such a hash of the documentation, I'm not even sure anymore.

For the OP's command:

select compid,2, convert(datetime, '01/01/' + CONVERT(char(4),cal_yr) ,101) ,0,  Update_dt, th1, th2, th3_pc , Update_id, Update_dt,1
from  #tmp_CTF** 

I get this error:

Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '*'.

when debugging something like this split the long line up so you'll get a better row number:

select compid
,2
, convert(datetime
, '01/01/' 
+ CONVERT(char(4)
,cal_yr) 
,101) 
,0
,  Update_dt
, th1
, th2
, th3_pc 
, Update_id
, Update_dt
,1
from  #tmp_CTF** 

this now results in:

Msg 102, Level 15, State 1, Line 16
Incorrect syntax near '*'.

which is probably just from the OP not putting the entire command in the question, or use [ ] braces to signify the table name:

from [#tmp_CTF**]

if that is the table name.

The data in COL1 is in dd-mon-yy

No it's not. A DATE column does not have any format. It is only converted (implicitely) to that representation by your SQL client when you display it.

If COL1 is really a DATE column using to_date() on it is useless because to_date() converts a string to a DATE.

You only need to_char(), nothing else:

SELECT TO_CHAR(col1, 'mm/dd/yyyy') 
FROM TABLE1

What happens in your case is that calling to_date() converts the DATE into a character value (applying the default NLS format) and then converting that back to a DATE. Due to this double implicit conversion some information is lost on the way.

Edit

So you did make that big mistake to store a DATE in a character column. And that's why you get the problems now.

The best (and to be honest: only sensible) solution is to convert that column to a DATE. Then you can convert the values to any rerpresentation that you want without worrying about implicit data type conversion.

But most probably the answer is "I inherited this model, I have to cope with it" (it always is, apparently no one ever is responsible for choosing the wrong datatype), then you need to use RR instead of YY:

SELECT TO_CHAR(TO_DATE(COL1,'dd-mm-rr'), 'mm/dd/yyyy')
FROM TABLE1

should do the trick. Note that I also changed mon to mm as your example is 27-11-89 which has a number for the month, not an "word" (like NOV)

Simple and not time consuming answer with an example relevant to the question asked Follow this example:

 user = [{"name": "Dough", "age": 55}, 
            {"name": "Ben", "age": 44}, 
            {"name": "Citrus", "age": 33},
            {"name": "Abdullah", "age":22},
            ]
    print(sorted(user, key=lambda el: el["name"]))
    print(sorted(user, key= lambda y: y["age"]))

Look at the names in the list, they starts with D, B, C and A. And if you notice the ages, they are 55, 44, 33 and 22. The first print code

print(sorted(user, key=lambda el: el["name"]))

Results to:

[{'name': 'Abdullah', 'age': 22}, 
{'name': 'Ben', 'age': 44}, 
{'name': 'Citrus', 'age': 33}, 
{'name': 'Dough', 'age': 55}]

sorts the name, because by key=lambda el: el["name"] we are sorting the names and the names return in alphabetical order.

The second print code

print(sorted(user, key= lambda y: y["age"]))

Result:

[{'name': 'Abdullah', 'age': 22},
 {'name': 'Citrus', 'age': 33},
 {'name': 'Ben', 'age': 44}, 
 {'name': 'Dough', 'age': 55}]

sorts by age, and hence the list returns by ascending order of age.

Try this code for better understanding.

In PHP any date can be converted into the required date format using different scenarios for example to change any date format into Day, Date Month Year

$newdate = date("D, d M Y", strtotime($date));

It will show date in the following very well format

Mon, 16 Nov 2020

To control the location of the title you may want to set a custom font as explained here (by twaddington): Link

Then to relocate the position of the text, in updateMeasureState() you would add p.baselineShift += (int) (p.ascent() * R); Similarly in updateDrawState() add tp.baselineShift += (int) (tp.ascent() * R); Where R is double between -1 and 1.

        paramTwo: "defaultValueTwo"
    }
});

2) In the controller:

.controller('editUserCtrl', function ($stateParams, $scope) {       
    $scope.paramOne = $stateParams.paramOne;
    $scope.paramTwo = $stateParams.paramTwo;
});

3A) Changing the State from a controller

$state.go("edit_user", {
    user_id: 1,                
    paramOne: { objectProperty: "test_not_default1" },
    paramTwo: "from controller"
});

3B) Changing the State in html

<div ui-sref="edit_user({ user_id: 3, paramOne: { objectProperty: 'from_html1' }, paramTwo: 'fromhtml2' })"></div>

Example Plunker

I got stuck during Android SDK Setup (API Level 19 and 21) Turning OFF and ON the Internet connection resolved the issue and the installation completed successfully.

What you are looking for is disabled="true". Here is an example:

<textarea class="customPayload" disabled="true" *ngIf="!showSpinner"></textarea>

import json
row = [1L,[0.1,0.2],[[1234L,1],[134L,2]]]
row_json = json.dumps(row)

You could also just modify the height for each row using CSS.

<head>
 <style>
 tr {
   height:40px;
 }
</style>
</head>

<body>
<table>

<tr> <td>One</td> <td>Two</td> </tr>
<tr> <td>Three</td> <td>Four</td> </tr>
<tr> <td>Five</td> <td>Six</td> </tr>

</table>
</body>

You could also modify the height of the <td> element, it should give you the same result.

Based around other posters answers, along with some samples of useage:

public static string FormatSortCode(string sortCode)
{
    return ChunkString(sortCode, 2, "-");
}
public static string FormatIBAN(string iban)
{
    return ChunkString(iban, 4, "  ");
}

private static string ChunkString(string str, int chunkSize, string separator)
{
    var b = new StringBuilder();
    var stringLength = str.Length;
    for (var i = 0; i < stringLength; i += chunkSize)
    {
        if (i + chunkSize > stringLength) chunkSize = stringLength - i;
        b.Append(str.Substring(i, chunkSize));
        if (i+chunkSize != stringLength)
            b.Append(separator);
    }
    return b.ToString();
}

Try this: Have a button/link which opens a webpage (in a new window) with just the pdf file embedded in it, and print the webpage.

In head of the main page:

<script type="text/javascript">
function printpdf() 
{
myWindow=window.open("pdfwebpage.html");
myWindow.close;  //optional, to close the new window as soon as it opens
//this ensures user doesn't have to close the pop-up manually
}
</script>

And in body of the main page:

<a href="printpdf()">Click to Print the PDF</a>

Inside pdfwebpage.html:

<html>
<head>    
</head>

<body onload="window.print()">
<embed src="pdfhere.pdf"/>

</body>
</html>

Just re-add the src argument on a separate line after the img oject is defined. This will trick IE into triggering the lad-event. It is ugly, but it is the simplest workaround I've found so far.

jQuery('<img/>', {
    src: url,
    id: 'whatever'
})
.load(function() {
})
.appendTo('#someelement');
$('#whatever').attr('src', url); // trigger .load on IE

string[] strArray = { "text1", "text2", "text3", "text4" };
string value = "text3";

if(Array.contains(strArray , value))
{
    // Do something if the value is available in Array.
}

You can ssh directly from the Terminal on Mac, but you need to use a .PEM key rather than the putty .PPK key. You can use PuttyGen on Windows to convert from .PEM to .PPK, I'm not sure about the other way around though.

You can also convert the key using putty for Mac via port or brew:

sudo port install putty

or

brew install putty

This will also install puttygen. To get puttygen to output a .PEM file:

puttygen privatekey.ppk -O private-openssh -o privatekey.pem

Once you have the key, open a terminal window and:

ssh -i privatekey.pem [email protected]

The private key must have tight security settings otherwise SSH complains. Make sure only the user can read the key.

chmod go-rw privatekey.pem

If you don't know when data will be added to #data, you could set an interval to update the element's scrollTop to its scrollHeight every couple of seconds. If you are controlling when data is added, just call the internal of the following function after the data has been added.

window.setInterval(function() {
  var elem = document.getElementById('data');
  elem.scrollTop = elem.scrollHeight;
}, 5000);

This is a possible generic implementation using a bit of reflection (pseudo-code, don't have VS now):

public class DtoMapper<DtoType>
{
    Dictionary<string,PropertyInfo> properties;

    public DtoMapper()
    {
        // Cache property infos
        var t = typeof(DtoType);
        properties = t.GetProperties().ToDictionary(p => p.Name, p => p);
     }

    public DtoType Map(Dto dto)
    {
        var instance = Activator.CreateInstance(typeOf(DtoType));

        foreach(var p in properties)
        {
            p.SetProperty(
                instance, 
                Convert.Type(
                    p.PropertyType, 
                    dto.Items[Array.IndexOf(dto.ItemsNames, p.Name)]);

            return instance;
        }
    }

Usage:

var mapper = new DtoMapper<Model>();
var modelInstance = mapper.Map(dto);

This will be slow when you create the mapper instance but much faster later.

Yes Jython does this, but it may or may not be what you want

Maybe it caused by Filename variable

File = TextBox1.Value

It should be

Filename = TextBox1.Value

I had the same exception installing using correct framework.

My solution was running cmd as administrator .... then it worked fine.

You can't use {{}} when using angular directives for binding with ng-model but for binding non-angular attributes you would have to use {{}}..

Eg:

ng-show="my-model"
title = "{{my-model}}"

You might also consider removing the need for duplicated parameter names in your Sql by changing your Sql to

table.Variable2 LIKE '%' || :VarB || '%'

and then getting your client to provide '%' for any value of VarB instead of null. In some ways I think this is more natural.

You could also change the Sql to

table.Variable2 LIKE '%' || IfNull(:VarB, '%') || '%'

Use include if you don't mind your script continuing without loading the file (in case it doesn't exist etc) and you can (although you shouldn't) live with a Warning error message being displayed.

Using require means your script will halt if it can't load the specified file, and throw a Fatal error.

I think you can just cast to ObjectNode and use put method. Like this

ObjectNode o = (ObjectNode) jsonNode; o.put("value", "NO");

How about creating another component(for object that needs to go into the array) and pass the following as props?

1. component index - index will be used to create/update in array.
2. set function - This function put data into the array based on the component index.

<SubObjectForm setData={this.setSubObjectData}                                                            objectIndex={index}/>

Here {index} can be passed in based on position where this SubObjectForm is used.

and setSubObjectData can be something like this.

 setSubObjectData: function(index, data){
      var arrayFromParentObject= <retrieve from props or state>;
      var objectInArray= arrayFromParentObject.array[index];
      arrayFromParentObject.array[index] = Object.assign(objectInArray, data);
 }

In SubObjectForm, this.props.setData can be called on data change as given below.

<input type="text" name="name" onChange={(e) => this.props.setData(this.props.objectIndex,{name: e.target.value})}/>

The shortest and easiest answer is: you shouldn't vertically center things in webpages. HTML and CSS simply are not created with that in mind. They are text formatting languages, not user interface design languages.

That said, this is the best way I can think of. However, this will NOT WORK in Internet Explorer 7 and below!

<style>
  html, body {
    height: 100%;
  }
  #tableContainer-1 {
    height: 100%;
    width: 100%;
    display: table;
  }
  #tableContainer-2 {
    vertical-align: middle;
    display: table-cell;
    height: 100%;
  }
  #myTable {
    margin: 0 auto;
  }
</style>
<div id="tableContainer-1">
  <div id="tableContainer-2">
    <table id="myTable" border>
      <tr><td>Name</td><td>J W BUSH</td></tr>
      <tr><td>Proficiency</td><td>PHP</td></tr>
      <tr><td>Company</td><td>BLAH BLAH</td></tr>
    </table>
  </div>
</div>

if (location.protocol == 'http:')
  location.href = location.href.replace(/^http:/, 'https:')

You can do this getting difference of .schema and .dump commands. for example with grep:

sqlite3 some.db .schema > schema.sql
sqlite3 some.db .dump > dump.sql
grep -vx -f schema.sql dump.sql > data.sql

data.sql file will contain only data without schema, something like this:

BEGIN TRANSACTION;
INSERT INTO "table1" VALUES ...;
...
INSERT INTO "table2" VALUES ...;
...
COMMIT;

I hope this helps you.

Tried all the above, use the Firebase Assistant! It is the simplest way to solve this. First remove all the dependencies you added to the build.gradle (using the manual method) and then in Android Studio:

Click Tools > Firebase to open the Assistant window.

It really is as easy as that.

The "problem" with the tabs is that they indent the text to fixed tab positions, typically multiples of 4 or 8 characters (depending on the console or editor displaying them). Your first filename is 7 chars, so the next tab stop after its end is at position 8. Your subsequent filenames however are 8 chars long, so the next tab stop is at position 12.

If you want to ensure that columns get nicely indented at the same position, you need to take into account the actual length of previous columns, and either modify the number of following tabs, or pad with the required number of spaces instead. The latter can be achieved using e.g. System.out.printf with an appropriate format specification (e.g. "%1$13s" specifies a minimum width of 13 characters for displaying the first argument as a string).

I was getting same error while I tried to connect mlab db that is because my organization network has some restriction, I switched to mobile hotspot and it worked.

Using the Promise pattern:

function getImage(url){
        return new Promise(function(resolve, reject){
            var img = new Image()
            img.onload = function(){
                resolve(url)
            }
            img.onerror = function(){
                reject(url)
            }
            img.src = url
        })
    }

And when calling the function we can handle its response or error quite neatly.

getImage('imgUrl').then(function(successUrl){
    //do stufff
}).catch(function(errorUrl){
    //do stuff
})

Edited for clarity:

This will work to to get the value if the remote.origin.url is in the form protocol://auth_info@git_host:port/project/repo.git. If you find it doesn't work, adjust the -f5 option that is part of the first cut command.

For the example remote.origin.url of protocol://auth_info@git_host:port/project/repo.git the output created by the cut command would contain the following:

-f1: protocol: -f2: (blank) -f3: auth_info@git_host:port -f4: project -f5: repo.git

If you are having problems, look at the output of the git config --get remote.origin.url command to see which field contains the original repository. If the remote.origin.url does not contain the .git string then omit the pipe to the second cut command.

#!/usr/bin/env bash
repoSlug="$(git config --get remote.origin.url | cut -d/ -f5 | cut -d. -f1)"
echo ${repoSlug}

I had this problem even after setting the config properly. git config

My scenario was issuing git command through supervisor (in Linux). On further debugging, supervisor was not reading the git config from home folder. Hence, I had to set the environment HOME variable in the supervisor config so that it can locate the git config correctly. It's strange that supervisor was not able to locate the git config just from the username configured in supervisor's config (/etc/supervisor/conf.d).

Though it won't work for numbers, you can check if the lowercase and uppercase values are same or not, For non-alphabetic characters they will be same, You should check for number before this for better usability

These are the best practices from Mozilla Developer Network's window.open page :

<script type="text/javascript">
var windowObjectReference = null; // global variable

function openFFPromotionPopup() {
  if(windowObjectReference == null || windowObjectReference.closed)
  /* if the pointer to the window object in memory does not exist
     or if such pointer exists but the window was closed */

  {
    windowObjectReference = window.open("http://www.spreadfirefox.com/",
   "PromoteFirefoxWindowName", "resizable,scrollbars,status");
    /* then create it. The new window will be created and
       will be brought on top of any other window. */
  }
  else
  {
    windowObjectReference.focus();
    /* else the window reference must exist and the window
       is not closed; therefore, we can bring it back on top of any other
       window with the focus() method. There would be no need to re-create
       the window or to reload the referenced resource. */
  };
}

I see you have all the settings right. You just need to end the local web server and start it again with

php artisan serve

Everytime you change your .env file, you need tor restart the server for the new options to take effect.

Or clear and cache your configuration with

php artisan config:cache

I'd git clone to a new directory and copy the content of the existing directory to the new clone.

http://dev.mysql.com/doc/refman/5.0/en/insert-select.html

For case1:

INSERT INTO TAB_STUDENT(name_student, id_teacher_fk)
SELECT 'Joe The Student', id_teacher
  FROM TAB_TEACHER
 WHERE name_teacher = 'Professor Jack'
 LIMIT 1

For case2 you just have to do 2 separate insert statements

One of my favorites is realpath foo

realpath - return the canonicalized absolute pathname

realpath  expands  all  symbolic  links  and resolves references to '/./', '/../' and extra '/' characters in the null terminated string named by path and
       stores the canonicalized absolute pathname in the buffer of size PATH_MAX named by resolved_path.  The resulting path will have no symbolic link, '/./' or
       '/../' components.

Add them to the allowed characters, but you'll need to escape some of them, such as -]/\

var pattern = /^[a-zA-Z0-9!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]*$/

That way you can remove any individual character you want to disallow.

Also, you want to include the start and end of string placemarkers ^ and $

Update:

As elclanrs understood (and the rest of us didn't, initially), the only special characters needing to be allowed in the pattern are &-._

/^[\w&.\-]+$/

[\w] is the same as [a-zA-Z0-9_]

Though the dash doesn't need escaping when it's at the start or end of the list, I prefer to do it in case other characters are added. Additionally, the + means you need at least one of the listed characters. If zero is ok (ie an empty value), then replace it with a * instead:

/^[\w&.\-]*$/

This is a Bash line that prints all available mac addresses, except the loopback:

for x in `ls /sys/class/net |grep -v lo`; do cat /sys/class/net/$x/address; done

Can be executed from a C program.

Apache Commons Lang

DateUtils.isSameDay(date1, date2)

http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/time/DateUtils.html#isSameDay(java.util.Date, java.util.Date)

Using max(date) didn't solve my problem as there is no assurance that other columns will be from the same row as the max(date) is. Instead of that this one solved my problem and sorted group by in a correct order and values of other columns are from the same row as the max date is:

SELECT model, date 
FROM (SELECT * FROM doc ORDER BY date DESC) as sortedTable
GROUP BY model

When you have changes on your working copy, from command line do:

git stash 

This will stash your changes and clear your status report

git pull

This will pull changes from upstream branch. Make sure it says fast-forward in the report. If it doesn't, you are probably doing an unintended merge

git stash pop

This will apply stashed changes back to working copy and remove the changes from stash unless you have conflicts. In the case of conflict, they will stay in stash so you can start over if needed.

if you need to see what is in your stash

git stash list

The answers above which talk about normalizing are great! But what if you find yourself in a position like me where you're not allowed to touch the database schema or structure as it stands? Eg, the DBA's are 'gods' and all suggested revisions go to /dev/null?

In that respect, I feel like this has been answered with this Stack Overflow posting too in regards to all the users above giving code samples.

I'm reposting the code from INSERT VALUES WHERE NOT EXISTS which helped me the most since I can't alter any underlying database tables:

INSERT INTO #table1 (Id, guidd, TimeAdded, ExtraData)
SELECT Id, guidd, TimeAdded, ExtraData
FROM #table2
WHERE NOT EXISTS (Select Id, guidd From #table1 WHERE #table1.id = #table2.id)
-----------------------------------
MERGE #table1 as [Target]
USING  (select Id, guidd, TimeAdded, ExtraData from #table2) as [Source]
(id, guidd, TimeAdded, ExtraData)
    on [Target].id =[Source].id
WHEN NOT MATCHED THEN
    INSERT (id, guidd, TimeAdded, ExtraData)
    VALUES ([Source].id, [Source].guidd, [Source].TimeAdded, [Source].ExtraData);
------------------------------
INSERT INTO #table1 (id, guidd, TimeAdded, ExtraData)
SELECT id, guidd, TimeAdded, ExtraData from #table2
EXCEPT
SELECT id, guidd, TimeAdded, ExtraData from #table1
------------------------------
INSERT INTO #table1 (id, guidd, TimeAdded, ExtraData)
SELECT #table2.id, #table2.guidd, #table2.TimeAdded, #table2.ExtraData
FROM #table2
LEFT JOIN #table1 on #table1.id = #table2.id
WHERE #table1.id is null

The above code uses different fields than what you have, but you get the general gist with the various techniques.

Note that as per the original answer on Stack Overflow, this code was copied from here.

Anyway my point is "best practice" often comes down to what you can and can't do as well as theory.

• If you're able to normalize and generate indexes/keys -- great!
• If not and you have the resort to code hacks like me, hopefully the above helps.

Good luck!

TypeScript isn't giving you a gun to shoot yourself in the foot with.

The iterator variable is a string because it is a string, full stop. Observe:

var obj = {};
obj['0'] = 'quote zero quote';
obj[0.0] = 'zero point zero';
obj['[object Object]'] = 'literal string "[object Object]"';
obj[<any>obj] = 'this obj'
obj[<any>undefined] = 'undefined';
obj[<any>"undefined"] = 'the literal string "undefined"';

for(var key in obj) {
    console.log('Type: ' + typeof key);
    console.log(key + ' => ' + obj[key]);
}

How many key/value pairs are in obj now? 6, more or less? No, 3, and all of the keys are strings:

Type: string
0 => zero point zero
Type: string
[object Object] => this obj; 
Type: string
undefined => the literal string "undefined" 

int uniqueId = 0;

int getUniqueId()
{
    return uniqueId++;
}

Add synchronized if you want it to be thread safe.

Disclaimer: I work at BrowserStack. ^{[Confirmed]that whether am allowed to post this (Can I suggest a product of the company am working at?)}

Debug Safari on iOS (not for Chrome as of now, read ahead for more details.)

How this works?

• You need to start a session on any real device (there are emulators but you need to start a session on a real device) on BrowserStack, say iPhone 6S - Safari / Chrome(no devtools for Chrome yet, but it is on our Roadmap)
• Type in the URL
• You can trigger DevTools to inspect the webpage opened on the BrowserStacks remote device. I've shared the screens for the same below.

Using DevTools with Real Phones

Hover over the elements, edit HTML, CSS just like desktop browser devtools work.

Executing JavaScript in real phone using DevTools

Switch to Console tab, execute JavaScript code, check console.log() output and so on...

Network tab, check request headers, response and so on...

Support for DevTools on BrowserStack?

• DevTools are available on :

  • Real Devices - iOS - Safari (DevTools for iOS Chrome is on our Roadmap)
  • Real Devices - Android - Chrome (Only Chrome is available on Android devices for now)

• Client browser needs to be Chrome or Firefox. That means you need to use Chrome or Firefox browser on MacOSX or Windows to use BrowserStack Real Device DevTools.

Note: You need to buy a plan to test on all real devices, as a free user, you'll get couple of Real Android devices (includes tablets) and couple of Real iOS devices (includes tablets). Also, emphasizing on the word Real Devices because they provide emulators as well.

More details on this, please refer to DevTools section on Mobile Features page.

Updated Answer

I've noticed a lot of people are using this answer so I decided to update it a little bit. If you want to see the original answer, check below. The new answer demonstrates how you can add some style to your list.

ul > li {_x000D_
    display: inline-block;_x000D_
    /* You can also add some margins here to make it look prettier */_x000D_
    zoom:1;_x000D_
    *display:inline;_x000D_
    /* this fix is needed for IE7- */_x000D_
}

<ul>_x000D_
    <li> <a href="#">some item</a>_x000D_

    <li> <a href="#">another item</a>_x000D_

    </li>_x000D_
</ul>

a.sum(0)

should solve the problem. It is a 2d np.array and you will get the sum of all column. axis=0 is the dimension that points downwards and axis=1 the one that points to the right.

Unmodifiable collections are usually read-only views (wrappers) of other collections. You can't add, remove or clear them, but the underlying collection can change.

Immutable collections can't be changed at all - they don't wrap another collection - they have their own elements.

Here's a quote from guava's ImmutableList

Unlike Collections.unmodifiableList(java.util.List<? extends T>), which is a view of a separate collection that can still change, an instance of ImmutableList contains its own private data and will never change.

So, basically, in order to get an immutable collection out of a mutable one, you have to copy its elements to the new collection, and disallow all operations.

Just add position:absolute; top:0; right:0; to the CSS for your button.

 #button {
     line-height: 12px;
     width: 18px;
     font-size: 8pt;
     font-family: tahoma;
     margin-top: 1px;
     margin-right: 2px;
     position:absolute;
     top:0;
     right:0;
 }

jsFiddle example

Remove @ResponseBody annotation from your use parameters in method. Like this;

   @Autowired
    ProjectService projectService;

    @RequestMapping(path = "/add", method = RequestMethod.POST)
    public ResponseEntity<Project> createNewProject(Project newProject){
        Project project = projectService.save(newProject);

        return new ResponseEntity<Project>(project,HttpStatus.CREATED);
    }

In Java, null only applies to object references; since boolean is a primitive type, it cannot be assigned null.

It's hard to get context from your example, but I'm guessing that if hideInNav is not in the object returned by getProperties(), the (default value?) you've indicated will be false. I suspect this is the bug that you're seeing, as false is not equal to null, so hideNavigation is getting the empty string?

You might get some better answers with a bit more context to your code sample.

I had the same problem, and I was using the following plugin for tests:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.9</version>
    <configuration>
        <useFile>true</useFile>
        <includes>
            <include>**/*Tests.java</include>
            <include>**/*Test.java</include>
        </includes>
        <excludes>
            <exclude>**/Abstract*.java</exclude>
        </excludes>
        <junitArtifactName>junit:junit</junitArtifactName>
        <parallel>methods</parallel>
        <threadCount>10</threadCount>
    </configuration>
</plugin>

The test were running fine in the IDE (eclipse sts), but failed when using command mvn test.

After a lot of trial and error, I figured the solution was to remove parallel testing, the following two lines from the plugin configuration above:

    <parallel>methods</parallel>
    <threadCount>10</threadCount>

Hope that this helps someone out!

If what is happening is that you have another server running on localhost and you want to give this new server a different local hostname like http://teamviewer/

I think that what you are actually looking for is Virtual Hosts functionality. I use Apache so I do not know how other web daemons support this. Maybe it is called Alias. Here is the Apache documentation:

Apache Virtual Hosts examples

I would not recommend you to start session just to get some unique id. Instead, use such things as uniqid() because it's intended to return unique id.

However, if you already have session, then, of course, use session_id() to get your session id - but do not rely on that, because "unique id" isn't same as "session id" in common sense: for example, multiple tabs in most browsers will use same process, thus, use same session identifier in result - and, therefore, different connections will have same id. It's your decision about desired behavior, I've mentioned this just to show the difference between session id and unique id.

I was interested in this as well and came across some examples on the Spring Boot site.

   // get with query string parameters e.g. /system/resource?id="rtze1cd2"&person="sam smith" 
// so below the first query parameter id is the variable and name is the variable
// id is shown below as a RequestParam
    @GetMapping("/system/resource")
    // this is for swagger docs
    @ApiOperation(value = "Get the resource identified by id and person")
    ResponseEntity<?> getSomeResourceWithParameters(@RequestParam String id, @RequestParam("person") String name) {

        logger.info("Request to get an id of "+id+" with a name of person: "+name);

        return new ResponseEntity<Object>(resource, HttpStatus.OK);

Update: as of the day of this writing, namedTuples are pickable (starting with python 2.7)

The issue here is the child processes aren't able to import the class of the object -in this case, the class P-, in the case of a multi-model project the Class P should be importable anywhere the child process get used

a quick workaround is to make it importable by affecting it to globals()

globals()["P"] = P

Another option that has not been mentioned is just creating the unit test class as a child of the object that you are testing. NUnit Example:

[TestFixture]
public class UnitTests : ObjectWithPrivateMethods
{
    [Test]
    public void TestSomeProtectedMethod()
    {
        Assert.IsTrue(this.SomeProtectedMethod() == true, "Failed test, result false");
    }
}

This would allow easy testing of private and protected (but not inherited private) methods, and it would allow you to keep all your tests separate from the real code so you aren't deploying test assemblies to production. Switching your private methods to protected methods would be acceptable in a lot of inherited objects, and it is a pretty simple change to make.

HOWEVER...

While this is an interesting approach to solving the problem of how to test hidden methods, I am unsure that I would advocate that this is the correct solution to the problem in all cases. It seems a little odd to be internally testing an object, and I suspect there might be some scenarios that this approach will blow up on you. (Immutable objects for example, might make some tests really hard).

While I mention this approach, I would suggest that this is more of a brainstormed suggestion than a legitimate solution. Take it with a grain of salt.

EDIT: I find it truly hilarious that people are voting this answer down, since I explicitly describe this as a bad idea. Does that mean that people are agreeing with me? I am so confused.....

Note: ioutil is deprecated as of Go 1.16.

If the file isn't too large, this can be done with the ioutil.ReadFile and strings.Split functions like so:

content, err := ioutil.ReadFile(filename)
if err != nil {
    //Do something
}
lines := strings.Split(string(content), "\n")

You can read the documentation on ioutil and strings packages.

I got to solve this issue by catching the position of the item that needed to be modified and then in the adapter call

public void refreshBlockOverlay(int position) {
    notifyItemChanged(position);
}

, this will call onBindViewHolder(ViewHolder holder, int position) for this specific item at this specific position.

make position absolute for that div.

If you want to add a custom highlighted color to your cell (and your cell contains buttons,labels, images,etc..) I followed the next steps:

For example if you want a selected yellow color:

1) Create a view that fits all the cell with 20% opacity (with yellow color) called for example backgroundselectedView

2) In the cell controller write this:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
     self.backgroundselectedView.alpha=1;
    [super touchesBegan:touches withEvent:event];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    self.backgroundselectedView.alpha=0;
    [super touchesEnded:touches withEvent:event];
}

- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
{
    self.backgroundSelectedImage.alpha=0;
    [super touchesCancelled:touches withEvent:event];
}

Follow these steps with Notepad++

1- Copy the original text

2- In Notepad++, open new file, change Encoding -> pick an encoding you think the original text follows. Try as well the encoding "ANSI" as sometimes Unicode files are read as ANSI by certain programs

3- Paste

4- Then to convert to Unicode by going again over the same menu: Encoding -> "Encode in UTF-8" (Not "Convert to UTF-8") and hopefully it will become readable

The above steps apply for most languages. You just need to guess the original encoding before pasting in notepad++, then convert through the same menu to an alternate Unicode-based encoding to see if things become readable.

Most languages exist in 2 forms of encoding: 1- The old legacy ANSI (ASCII) form, only 8 bits, was used initially by most computers. 8 bits only allowed 256 possibilities, 128 of them where the regular latin and control characters, the final 128 bits were read differently depending on the PC language settings 2- The new Unicode standard (up to 32 bit) give a unique code for each character in all currently known languages and plenty more to come. if a file is unicode it should be understood on any PC with the language's font installed. Note that even UTF-8 goes up to 32 bit and is just as broad as UTF-16 and UTF-32 only it tries to stay 8 bits with latin characters just to save up disk space

I got the same error but I was trying to run a node application using a Docker container.

I fixed it by adding a .dockerignore file to ignore the node_modules directory to make sure that when the docker image builds, it builds the native packages for the image I wanted (Alpine) instead of copying over the node_modules compiled for my host (Debian).

From Stack Overflow question What is the Python 3 equivalent of "python -m SimpleHTTPServer":

The following works for me:

python -m http.server [<portNo>]

Because I am using Python 3 the module SimpleHTTPServer has been replaced by http.server, at least in Windows.

Use:

export LANGUAGE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_CTYPE=en_US.UTF-8

It works for Debian. I don't know why - but locale-gen had not results.

Important! It's a temporary solution. It has to be run for each session.

Bash supports all sorts of wildcards and expansions.

Your exact case would be handled by brace expansion, like so:

$ rm -rf abc.log.2012-03-{14,27,28}

The above would expand to a single command with all three arguments, and be equivalent to typing:

$ rm -rf abc.log.2012-03-14 abc.log.2012-03-27 abc.log.2012-03-28

It's important to note that this expansion is done by the shell, before rm is even loaded.

Why not:

onItemClick: function (event) {

    event.currentTarget.style.backgroundColor = '#ccc';

},

render: function() {
    return (
        <div>
            <ul>
                <li onClick={this.onItemClick}>Component 1</li>
            </ul>
        </div>
    );
}

And if you want to be more React-ive about it, you might want to set the selected item as state of its containing React component, then reference that state to determine the item's color within render:

onItemClick: function (event) {

    this.setState({ selectedItem: event.currentTarget.dataset.id });
    //where 'id' =  whatever suffix you give the data-* li attribute
},

render: function() {
    return (
        <div>
            <ul>
                <li onClick={this.onItemClick} data-id="1" className={this.state.selectedItem == 1 ? "on" : "off"}>Component 1</li>
                <li onClick={this.onItemClick} data-id="2" className={this.state.selectedItem == 2 ? "on" : "off"}>Component 2</li>
                <li onClick={this.onItemClick} data-id="3" className={this.state.selectedItem == 3 ? "on" : "off"}>Component 3</li>
            </ul>
        </div>
    );
},

You'd want to put those <li>s into a loop, and you need to make the li.on and li.off styles set your background-color.

For dynamic SQL use:

'IN(' ||array_to_string(some_array, ',')||')'

Example

DO LANGUAGE PLPGSQL $$

DECLARE
    some_array bigint[];
    sql_statement text;

BEGIN

    SELECT array[1, 2] INTO some_array;
    RAISE NOTICE '%', some_array;

    sql_statement := 'SELECT * FROM my_table WHERE my_column IN(' ||array_to_string(some_array, ',')||')';
    RAISE NOTICE '%', sql_statement;

END;

$$;

Result: NOTICE: {1,2} NOTICE: SELECT * FROM my_table WHERE my_column IN(1,2)

There are a couple of answers posted here that will give you the text effects you want, but...

The thing about tables is that they are organized collections of labels and data. Having both a label ("Datum") and the value that it labels in the same cell is oh so very wrong. The label should be in a <th> element, with the value in a <td> either in the same row or the same column (depending on the data arrangement you are trying to achieve). You can have <th> elements running either vertically or horizontally or both, but if you don't have heading cells (which is what <th> means), you don't have a table, you just have a meaningless grid of text. It would be preferable, too, to have a <caption> element to label the table as a whole (you don't have to display the caption, but it should be there for accessibility) and have a summary="blah blah blah" attribute in the table tag, again for accessibility. So your HTML should probably look a lot more like this:

<html>
  <head>
    <title>Test page with Table<title>
    <style type="text/css">
      th {
        font-size: 35px;
        font-weight: bold;
        padding-left: 5px;
        padding-bottom: 3px;
      }
    </style>
  </head>
  <body>
    <table id="table_1" summary="This table has both labels and values">
      <caption>Table of Stuff</caption>
      <tr>
        <th>Datum</th>
        <td>November 2010</td>
      </tr>
    </table>
  </body>
</html>

That may not be exactly what you want -- it's hard to tell whether November 2010 is a data point or a label from what you've posted, and "Datum" isn't a helpful label in any case. Play with it a bit, but make sure that when your table is finished it actually has some kind of semantic meaning. If it's not a real table of data, then don't use a <table> to lay it out.

Here's another option:

df.replace(to_replace=[None], value=np.nan, inplace=True)

I used Allatori and it did its job pretty well.

I made a reactive version that accepts callbacks for stdOut and StdErr.
onStdOut and onStdErr are called asynchronously,
as soon as data arrives (before the process exits).

public static Int32 RunProcess(String path,
                               String args,
                       Action<String> onStdOut = null,
                       Action<String> onStdErr = null)
    {
        var readStdOut = onStdOut != null;
        var readStdErr = onStdErr != null;

        var process = new Process
        {
            StartInfo =
            {
                FileName = path,
                Arguments = args,
                CreateNoWindow = true,
                UseShellExecute = false,
                RedirectStandardOutput = readStdOut,
                RedirectStandardError = readStdErr,
            }
        };

        process.Start();

        if (readStdOut) Task.Run(() => ReadStream(process.StandardOutput, onStdOut));
        if (readStdErr) Task.Run(() => ReadStream(process.StandardError, onStdErr));

        process.WaitForExit();

        return process.ExitCode;
    }

    private static void ReadStream(TextReader textReader, Action<String> callback)
    {
        while (true)
        {
            var line = textReader.ReadLine();
            if (line == null)
                break;

            callback(line);
        }
    }

Example usage

The following will run executable with args and print

• stdOut in white
• stdErr in red

to the console.

RunProcess(
    executable,
    args,
    s => { Console.ForegroundColor = ConsoleColor.White; Console.WriteLine(s); },
    s => { Console.ForegroundColor = ConsoleColor.Red;   Console.WriteLine(s); } 
);

I found that the useful getResources().getColor(R.color.color_name) is deprecated.

It is not deprecated in API Level 21, according to the documentation.

It is deprecated in the M Developer Preview. However, the replacement method (a two-parameter getColor() that takes the color resource ID and a Resources.Theme object) is only available in the M Developer Preview.

Hence, right now, continue using the single-parameter getColor() method. Later this year, consider using the two-parameter getColor() method on Android M devices, falling back to the deprecated single-parameter getColor() method on older devices.

Why use a clumsy for loop with an index when you have the enhanced for loop?

private double calculateAverage(List <Integer> marks) {
  Integer sum = 0;
  if(!marks.isEmpty()) {
    for (Integer mark : marks) {
        sum += mark;
    }
    return sum.doubleValue() / marks.size();
  }
  return sum;
}

For tools like jarsigner which is implemented in Java.

JAVA_TOOL_OPTIONS=-Duser.language=en jarsigner

Just create hide and show methods yourself for all elements, as follows

Element.prototype.hide = function() {
    this.style.display = 'none';
}
Element.prototype.show = function() {
    this.style.display = '';
}

After this you can use the methods with the usual element identifiers like in these examples:

document.getElementByTagName('div')[3].hide();
document.getElementById('thing').show();

or:

<img src="removeME.png" onclick="this.hide()">

Your model is @Messages, change it to @message.

To change it like you should use migration:

def change   rename_table :old_table_name, :new_table_name end 

Of course do not create that file by hand but use rails generator:

rails g migration ChangeMessagesToMessage 

That will generate new file with proper timestamp in name in 'db dir. Then run:

rake db:migrate 

And your app should be fine since then.

There is a solution to create file (on external cache dir or anywhere else) and put this file's uri as output extra to camera intent - this will define path where taken picture will be stored.

Here is an example:

File file;
Uri fileUri;
final int RC_TAKE_PHOTO = 1;

    private void takePhoto() {
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        file = new File(getActivity().getExternalCacheDir(), 
                String.valueOf(System.currentTimeMillis()) + ".jpg");
        fileUri = Uri.fromFile(file);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
        getActivity().startActivityForResult(intent, RC_TAKE_PHOTO);

    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RC_TAKE_PHOTO && resultCode == RESULT_OK) {

                //do whatever you need with taken photo using file or fileUri

            }
        }
    }

Then if you don't need the file anymore, you can delete it using file.delete();

By the way, files from cache dir will be removed when user clears app's cache from apps settings.

Use Notification Center in the viewDidLoad: method of your ViewController to call a method and from there do what you were supposed to do in your viewWillAppear: method. Calling viewWillAppear: directly is not a good option.

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSLog(@"view did load");

    [[NSNotificationCenter defaultCenter] addObserver:self 
        selector:@selector(applicationIsActive:) 
        name:UIApplicationDidBecomeActiveNotification 
        object:nil];

    [[NSNotificationCenter defaultCenter] addObserver:self 
        selector:@selector(applicationEnteredForeground:) 
        name:UIApplicationWillEnterForegroundNotification
        object:nil];
}

- (void)applicationIsActive:(NSNotification *)notification {
    NSLog(@"Application Did Become Active");
}

- (void)applicationEnteredForeground:(NSNotification *)notification {
    NSLog(@"Application Entered Foreground");
}

Private Sub Form_Load()
    Dim s As String

    s = "test" & vbCrLf & "this" & vbCrLf & vbCrLf
    Debug.Print (s & Len(s))

    s = Left(s, Len(s) - Len(vbCrLf))
    Debug.Print (s & Len(s))
End Sub

Another option would be to use R via a small bash wrapper for convenience:

xlsx2txt(){
echo '
require(xlsx)
write.table(read.xlsx2(commandArgs(TRUE)[1], 1), stdout(), quote=F, row.names=FALSE, col.names=T, sep="\t")
' | Rscript --vanilla - $1 2>/dev/null
}

xlsx2txt file.xlsx > file.txt

System.err.println("Someone is Restarting me...");
setVisible(false);
try {
    Thread.sleep(600);
} catch (InterruptedException e1) {
    e1.printStackTrace();
}
setVisible(true);

I guess you don't really want to stop the application, but to "Restart" it. For that, you could use this and add your "Reset" before the sleep and after the invisible window.

You have to create a different values folder for different screens and put dimens.xml file according to densities.

1) values

2) values-hdpi (320x480 ,480x800)

3) values-large-hdpi (600x1024)

4) values-xlarge (720x1280 ,768x1280 ,800x1280 ,Nexus7 ,Nexus10)

5) values-sw480dp (5.1' WVGA screen)

6) values-xhdpi (Nexus4 , Galaxy Nexus)

Alan already gave you the right answer - use the sAMAccountName to filter your user.

I would add a recommendation on your use of DirectorySearcher - if you only want one or two pieces of information, add them into the "PropertiesToLoad" collection of the DirectorySearcher.

Instead of retrieving the whole big user object and then picking out one or two items, this will just return exactly those bits you need.

Sample:

adSearch.PropertiesToLoad.Add("sn");  // surname = last name
adSearch.PropertiesToLoad.Add("givenName");  // given (or first) name
adSearch.PropertiesToLoad.Add("mail");  // e-mail addresse
adSearch.PropertiesToLoad.Add("telephoneNumber");  // phone number

Those are just the usual AD/LDAP property names you need to specify.

This worked for me:

1. Add the directory which contains the editor's executable to your PATH variable. (E.g. "C:\Program Files\Sublime Text 3\")
2. Reboot your computer.
3. Change the core.editor global Git variable to the name of the editor executable without the extension '.exe' (e.g. git config --global core.editor sublime_text)

That's it!

NOTE: Sublime Text 3 is the editor I used for this example.

case when field1>0 then field2/field1 else 0 end as field3

Although this question is related to string conversion, I stumbled upon this while wanting an easy way to write arrays to my log files. If you just want the info, and don't care about the exact cleanliness of a string you might consider:

json_encode($array)

Sometime even after setting all it may not work. I have tried all the methods like

1. Setting the proxy in Emulator APN
2. Setting it thru eclipse preferences --> Android --> Launch

Nothing worked. Then I did the following which worked instantly.

Goto eclipse Run --> run configurations. Under Android Applications you can see you application. Now, on the right hand side click on the Target tab. Under the 'Additional Emulator Command line options' add the following.

-dns-server <DNS servers from your local machine upto three> -http-proxy http://<your proxy>:<your proxy port>

The catch here is that the DNS Server setting should be from your local system. Goto cmd prompt and run ipconfig to check your DNS servers. Same with the proxy server and port. Whatever works for your browser should be put in here.

I like to write two or more test methods to execute on parallel threads, and each of them make calls into the object under test. I've been using Sleep() calls to coordinate the order of the calls from the different threads, but that's not really reliable. It's also a lot slower because you have to sleep long enough that the timing usually works.

I found the Multithreaded TC Java library from the same group that wrote FindBugs. It lets you specify the order of events without using Sleep(), and it's reliable. I haven't tried it yet.

The biggest limitation to this approach is that it only lets you test the scenarios you suspect will cause trouble. As others have said, you really need to isolate your multithreaded code into a small number of simple classes to have any hope of thoroughly testing them.

Once you've carefully tested the scenarios you expect to cause trouble, an unscientific test that throws a bunch of simultaneous requests at the class for a while is a good way to look for unexpected trouble.

Update: I've played a bit with the Multithreaded TC Java library, and it works well. I've also ported some of its features to a .NET version I call TickingTest.

How about dictionary comprehensions?

>>> mylist = [3, 2, 1, 3, 4, 4, 4, 5, 5, 3]

>>> {x:1 for x in mylist}.keys()
[1, 2, 3, 4, 5]

EDIT To @Danny's comment: my original suggestion does not keep the keys ordered. If you need the keys sorted, try:

>>> from collections import OrderedDict

>>> OrderedDict( (x,1) for x in mylist ).keys()
[3, 2, 1, 4, 5]

which keeps elements in the order by the first occurrence of the element (not extensively tested)

Roll-your-own generic converter for complex objects as selected item

The Balusc gives a very useful overview answer on this subject. But there is one alternative he does not present: The Roll-your-own generic converter that handles complex objects as the selected item. This is very complex to do if you want to handle all cases, but pretty simple for simple cases.

The code below contains an example of such a converter. It works in the same spirit as the OmniFaces SelectItemsConverter as it looks through the children of a component for UISelectItem(s) containing objects. The difference is that it only handles bindings to either simple collections of entity objects, or to strings. It does not handle item groups, collections of SelectItems, arrays and probably a lot of other things.

The entities that the component binds to must implement the IdObject interface. (This could be solved in other way, such as using toString.)

Note that the entities must implement equals in such a way that two entities with the same ID compares equal.

The only thing that you need to do to use it is to specify it as converter on the select component, bind to an entity property and a list of possible entities:

<h:selectOneMenu value="#{bean.user}" converter="selectListConverter">
  <f:selectItem itemValue="unselected" itemLabel="Select user..."/>
  <f:selectItem itemValue="empty" itemLabel="No user"/>
  <f:selectItems value="#{bean.users}" var="user" itemValue="#{user}" itemLabel="#{user.name}" />
</h:selectOneMenu>

Converter:

/**
 * A converter for select components (those that have select items as children).
 * 
 * It convertes the selected value string into one of its element entities, thus allowing
 * binding to complex objects.
 * 
 * It only handles simple uses of select components, in which the value is a simple list of
 * entities. No ItemGroups, arrays or other kinds of values.
 * 
 * Items it binds to can be strings or implementations of the {@link IdObject} interface.
 */
@FacesConverter("selectListConverter")
public class SelectListConverter implements Converter {

  public static interface IdObject {
    public String getDisplayId();
  }

  @Override
  public Object getAsObject(FacesContext context, UIComponent component, String value) {
    if (value == null || value.isEmpty()) {
      return null;
    }

    return component.getChildren().stream()
      .flatMap(child -> getEntriesOfItem(child))
      .filter(o -> value.equals(o instanceof IdObject ? ((IdObject) o).getDisplayId() : o))
      .findAny().orElse(null);
  }

  /**
   * Gets the values stored in a {@link UISelectItem} or a {@link UISelectItems}.
   * For other components returns an empty stream.
   */
  private Stream<?> getEntriesOfItem(UIComponent child) {
    if (child instanceof UISelectItem) {
      UISelectItem item = (UISelectItem) child;
      if (!item.isNoSelectionOption()) {
        return Stream.of(item.getValue());
      }

    } else if (child instanceof UISelectItems) {
      Object value = ((UISelectItems) child).getValue();

      if (value instanceof Collection) {
        return ((Collection<?>) value).stream();
      } else {
        throw new IllegalStateException("Unsupported value of UISelectItems: " + value);
      }
    }

    return Stream.empty();
  }

  @Override
  public String getAsString(FacesContext context, UIComponent component, Object value) {
    if (value == null) return null;
    if (value instanceof String) return (String) value;
    if (value instanceof IdObject) return ((IdObject) value).getDisplayId();

    throw new IllegalArgumentException("Unexpected value type");
  }

}

 ngAfterViewInit() {
   setTimeout(() => {
     this.renderWidgetInsideWidgetContainer();
   }, 0);
  }

That is a good solution to resolve this problem.
