Besides below answer, if you have this error in console ([$injector:nomod], MINERR_ASSET:22), but everything seems to work fine, make sure that you don't have duplicate includes in your index.html.

Because this error can also be raised if you have duplicate includes of the files, that use this module, and are included before the file with actual module declaration.

When your button is disabled it directly sets the opacity. So first of all we have to set its opacity as

.v-button{
    opacity:1;    
}

Another solution, You can just iterate over the object keys like so, Note: you must use an instantiated object with existing properties:

printTypeNames<T>(obj: T) {
    const objectKeys = Object.keys(obj) as Array<keyof T>;
    for (let key of objectKeys)
    {
       console.log('key:' + key);
    }
}

Yes, it's the right way. You can use images in the Resource file using a path:

<StackPanel Orientation="Horizontal">
    <CheckBox  Content="{Binding Nname}" IsChecked="{Binding IsChecked}"/>
    <Image Source="E:\SWorking\SharePointSecurityApps\SharePointSecurityApps\SharePointSecurityApps.WPF\Images\sitepermission.png"/>
    <TextBlock Text="{Binding Path=Title}"></TextBlock>
</StackPanel>

Just restating what Tomasz said.

There are many examples of FOO__in=... style filters in the many-to-many and many-to-one tests. Here is syntax for your specific problem:

users_in_1zone = User.objects.filter(zones__id=<id1>)
# same thing but using in
users_in_1zone = User.objects.filter(zones__in=[<id1>])

# filtering on a few zones, by id
users_in_zones = User.objects.filter(zones__in=[<id1>, <id2>, <id3>])
# and by zone object (object gets converted to pk under the covers)
users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3])

The double underscore (__) syntax is used all over the place when working with querysets.

I would use:

val, idx = min((val, idx) for (idx, val) in enumerate(my_list))

Then val will be the minimum value and idx will be its index.

You should done my guideline:
1. Add bellow source into Gemfile

source 'https://rails-assets.org' do
  gem 'rails-assets-tether', '>= 1.1.0'
end

2. Run command:

   bundle install

3. Add this line after jQuery in application.js.

   //= require jquery
   //= require tether

4. Restart rails server.

If you want to see the array as an array, you can say

alert(JSON.stringify(aCustomers));

instead of all those document.writes.

However, if you want to display them cleanly, one per line, in your popup, do this:

alert(aCustomers.join("\n"));

I create a method to simplify this:

    public static void drawCenterText(String text, RectF rectF, Canvas canvas, Paint paint) {
    Paint.Align align = paint.getTextAlign();
    float x;
    float y;
    //x
    if (align == Paint.Align.LEFT) {
        x = rectF.centerX() - paint.measureText(text) / 2;
    } else if (align == Paint.Align.CENTER) {
        x = rectF.centerX();
    } else {
        x = rectF.centerX() + paint.measureText(text) / 2;
    }
    //y
    metrics = paint.getFontMetrics();
    float acent = Math.abs(metrics.ascent);
    float descent = Math.abs(metrics.descent);
    y = rectF.centerY() + (acent - descent) / 2f;
    canvas.drawText(text, x, y, paint);

    Log.e("ghui", "top:" + metrics.top + ",ascent:" + metrics.ascent
            + ",dscent:" + metrics.descent + ",leading:" + metrics.leading + ",bottom" + metrics.bottom);
}

rectF is the area you want draw the text,That's it. Details

Instead of Str(RequestID), try convert(varchar(38), RequestID)

Use the % instead of the / when you divide. This will return the remainder for you. So in your case

26 % 7 = 5

Suppose, You want to add click event like this main.xml

<Button
    android:id="@+id/btn_register"
    android:layout_margin="1dp"
    android:layout_marginLeft="3dp"
    android:layout_marginTop="10dp"
    android:layout_weight="2"
    android:onClick="register"
    android:text="Register"
    android:textColor="#000000"/>

In java file, you have to write a method like this method.

public void register(View view) {
}

iOS 4.3.2's User Agent, which came out this week, is:

Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_3_2 like Mac OS X; en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8H7 Safari/6533.18.5

scanf needs to know the size of the data being pointed at by &d to fill it properly, whereas variadic functions promote floats to doubles (not entirely sure why), so printf is always getting a double.

I wasted a lot of time because of this issue. Finally I found great solution myself. Before I was using .ttf font only. But I added one extra font format .eot that started to work in IE.

I used following code and it worked like charm in all browsers.

@font-face {
font-family: OpenSans;
src: url(assets/fonts/OpenSans/OpenSans-Regular.ttf), 
url(assets/fonts/OpenSans/OpenSans-Regular.eot);
}

@font-face {
font-family: OpenSans Bold;
src: url(assets/fonts/OpenSans/OpenSans-Bold.ttf),
url(assets/fonts/OpenSans/OpenSans-Bold.eot);
}

I hope this will help someone.

Here's how I did it...

    public static ElementDefinitionImpl[] RemoveElementDefAt(
        ElementDefinition[] oldList,
        int removeIndex
    )
    {
        ElementDefinitionImpl[] newElementDefList = new ElementDefinitionImpl[ oldList.Length - 1 ];

        int offset = 0;
        for ( int index = 0; index < oldList.Length; index++ )
        {
            ElementDefinitionImpl elementDef = oldList[ index ] as ElementDefinitionImpl;
            if ( index == removeIndex )
            {
                //  This is the one we want to remove, so we won't copy it.  But 
                //  every subsequent elementDef will by shifted down by one.
                offset = -1;
            }
            else
            {
                newElementDefList[ index + offset ] = elementDef;
            }
        }
        return newElementDefList;
    }

You don't need any special library or "dangerous" attribute. You can just use React Refs to manipulate the DOM:

class MyComponent extends React.Component {
    
    constructor(props) {
        
        super(props);       
        this.divRef = React.createRef();
        this.myHTML = "<p>Hello World!</p>"
    }
    
    componentDidMount() {
        
        this.divRef.current.innerHTML = this.myHTML;
    }
    
    render() {
        
        return (
            
            <div ref={this.divRef}></div>
        );
    }
}

One of the goals of compilers is to rule out classes of errors. Some unreachable code is there by accident, it's nice that javac rules out that class of error at compile time.

For every rule that catches erroneous code, someone will want the compiler to accept it because they know what they're doing. That's the penalty of compiler checking, and getting the balance right is one of the tricker points of language design. Even with the strictest checking there's still an infinite number of programs that can be written, so things can't be that bad.

I am not sure, but might be what you want:

var c = 0;
function setBgPosition()
{
    var numbers = [0, -120, -240, -360, -480, -600, -720];
    function run()
    {
        Ext.get('common-spinner').setStyle('background-position', numbers[c++] + 'px 0px');
        if (c<=numbers.length)
        {
            setTimeout(run, 200);
        }
        else
        {
            Ext.get('common-spinner').setStyle('background-position', numbers[0] + 'px 0px');
        }
    }
    setTimeout(run, 200);
}
setBgPosition();

you can see the solution on http://jsfiddle.net/CBQCA/1/

OR

<table style="height:100%;width:100%; position: absolute; top: 0; bottom: 0; left: 0; right: 0;border:1px solid">
     <tr style="height: 25%;">
        <td>Region</td>
    </tr>
    <tr style="height: 75%;">
        <td>100.00%</td>
    </tr>
</table>?

I removed the font size, to show that columns are expanded. I added border:1px solid just to make sure table is expanded. you can remove it.

parentNode.insertBefore(newChild, refChild)

Inserts the node newChild as a child of parentNode before the existing child node refChild. (Returns newChild.)

If refChild is null, newChild is added at the end of the list of children. Equivalently, and more readably, use parentNode.appendChild(newChild).

As Peter already pointed out:

In [1]: import requests

In [2]: r = requests.get('https://api.github.com/events')

In [3]: type(r)
Out[3]: requests.models.Response

In [4]: type(r.content)
Out[4]: str

You may also want to check r.text.

Did you try the || operator ?

Concatenation Operator Documentation from Oracle >>>

One line if:

<statement> if <condition>

Your case:

"Yes" if @item.rigged

"No" if [email protected] # or: "No" unless @item.rigged

Another pure BASH way:

> s='/some/random/file.csv:some string'
> echo "${s%%:*}"
/some/random/file.csv

You can use the include? method:

my_string = "abcdefg"
if my_string.include? "cde"
   puts "String includes 'cde'"
end

You can do something like:

s = np.random.normal(2, 3, 1000)
import matplotlib.pyplot as plt
count, bins, ignored = plt.hist(s, 30, density=True)
plt.plot(bins, 1/(3 * np.sqrt(2 * np.pi)) * np.exp( - (bins - 2)**2 / (2 * 3**2) ), 
linewidth=2, color='r')
plt.show()

It's a good practice to initialize the local variables inside the method block before using it. Here is a mistake that a beginner may commit.

  public static void main(String[] args){
    int a;
    int[] arr = {1,2,3,4,5};
    for(int i=0; i<arr.length; i++){
        a = arr[i];
    }
    System.out.println(a);
  }

You may expect the console will show '5' but instead the compiler will throw 'variable a might not be initialized' error. Though one may think variable a is 'initialized' inside the for loop, the compiler does not think in that way. What if arr.length is 0? The for loop will not be run at all. Hence, the compiler will give variable a might not have been initialized to point out the potential danger and require you to initialize the variable.

To prevent this kind of error, just initialize the variable when you declare it.

int a = 0;

You could created sorted list from Values and rebuild the dictionary:

myDictionary={"two":"2", "one":"1", "five":"5", "1four":"4"}

newDictionary={}

sortedList=sorted(myDictionary.values())

for sortedKey in sortedList:
    for key, value in myDictionary.items():
        if value==sortedKey:
            newDictionary[key]=value

Output: newDictionary={'one': '1', 'two': '2', '1four': '4', 'five': '5'}

function escapeHTML(string)
    {

        return pre.innerHTML;
}//end escapeHTML

it will return the escaped Html

one-way Data Flow, according to https://vuejs.org/v2/guide/components.html, the component follow one-Way Data Flow, All props form a one-way-down binding between the child property and the parent one, when the parent property updates, it will flow down to the child but not the other way around, this prevents child components from accidentally mutating the parent's, which can make your app's data flow harder to understand.

In addition, every time the parent component is updates all props in the child components will be refreshed with the latest value. This means you should not attempt to mutate a prop inside a child component. If you do .vue will warn you in the console.

There are usually two cases where it’s tempting to mutate a prop: The prop is used to pass in an initial value; the child component wants to use it as a local data property afterwards. The prop is passed in as a raw value that needs to be transformed. The proper answer to these use cases are: Define a local data property that uses the prop’s initial value as its initial value:

props: ['initialCounter'],
data: function () {
  return { counter: this.initialCounter }
}

Define a computed property that is computed from the prop’s value:

props: ['size'],
computed: {
  normalizedSize: function () {
    return this.size.trim().toLowerCase()
  }
}

It seems as though there are multiple rows in the DATA.Dim_Member table per SUSP.Susp_Visits row.

If anyone is looking for a quick fix for this, here's how you do it.

while (array[i] != '\0') i++;

The variable i will hold the used length of the array, not the entire initialized array. I know it's a late post, but it may help someone.

As the error says Failed to find build Tools revision 23.0.1 This means that in your project you have used buildToolsVersion "23.0.3" So,You need to download the exact same version this makes the error disappear

**Step 1:**
GO to Tools and click SDK Manager
**Step 2:**
you can see SDK Platforms ,SDK Tools and SDK update Sites
**Step3:**
Click SDK Tools and click show package details
**Step 4:**
Select the version that you have mentioned in your Project 

These Steps has solved my issue.

gswin64c -sDEVICE=txtwrite -o output.txt input.pdf

The output file was split into pages with headers, etc., but it was then easy to write an app to strip out blank lines, etc, and suck in all 30,000 records. -dSIMPLE and -dCOMPLEX made no difference in this case.

Here's what worked for me:

To enable support for JSPs, we would need to add a dependency on tomcat-embed-jasper.

I was facing the same issue with jenkins ssh slave 'jenkinsci/ssh-slave'. However, my case was a bit complicated because it was necessary to pass an argument which contained spaces. I've managed to do it like below (entrypoint in dockerfile is in exec form):

command: ["some argument with space which should be treated as one"]

Only this worked for me:

$(document).ready(function(){
    $('select').not('.disabled').formSelect();
});

You need to do it on the UI thread. Use:

Dispatcher.BeginInvoke(new Action(() => {GetGridData(null, 0)})); 

You could print the backspace character \b as many times as the characters which were printed before.

System.out.print("hello");
Thread.sleep(1000); // Just to give the user a chance to see "hello".
System.out.print("\b\b\b\b\b");
System.out.print("world");

Note: this doesn't work flawlessly in Eclipse console in older releases before Mars (4.5). This works however perfectly fine in command console. See also How to get backspace \b to work in Eclipse's console?

If you just need to read the data.

encrypt(str.data(),str.size());

If you need a read/write copy of the data put it into a vector. (Don;t dynamically allocate space that's the job of vector).

std::vector<byte>  source(str.begin(),str.end());
encrypt(&source[0],source.size());

Of course we are all assuming that byte is a char!!!

Inspired by samneric's answer using DataRowComparer.Default but needing something that would only compare a subset of columns within a DataTable, I made a DataTableComparer object where you can specify which columns to use in the comparison. Especially great if they have different columns/schemas.

DataRowComparer.Default works because it implements IEqualityComparer. Then I created an object where you can define which columns of the DataRow will be compared.

public class DataTableComparer : IEqualityComparer<DataRow>
{
    private IEnumerable<String> g_TestColumns;
    public void SetCompareColumns(IEnumerable<String> p_Columns)
    {
        g_TestColumns = p_Columns; 
    }

    public bool Equals(DataRow x, DataRow y)
    {

        foreach (String sCol in g_TestColumns)
            if (!x[sCol].Equals(y[sCol])) return false;

        return true;
    }

    public int GetHashCode(DataRow obj)
    {
        StringBuilder hashBuff = new StringBuilder();

        foreach (String sCol in g_TestColumns)
            hashBuff.AppendLine(obj[sCol].ToString());               

        return hashBuff.ToString().GetHashCode();

    }
}

You can use this by:

DataTableComparer comp = new DataTableComparer();
comp.SetCompareColumns(new String[] { "Name", "DoB" });

DataTable celebrities = SomeDataTableSource();
DataTable politicians = SomeDataTableSource2();

List<DataRow> celebrityPoliticians = celebrities.AsEnumerable().Intersect(politicians.AsEnumerable(), comp).ToList();

Since 0.11 hive has a NVL function nvl(T value, T default_value)

which says Returns default value if value is null else returns value

This is working for me (i use laravel 5.6).

Try this code, I used the following code for cloning and removing the cloned element, i have also used new class (newClass) which can be added automatically with the newly cloned html

for cloning..

 $(".tr_clone_add").live('click', function() {
    var $tr    = $(this).closest('.tr_clone');
    var newClass='newClass';
    var $clone = $tr.clone().addClass(newClass);
    $clone.find(':text').val('');
    $tr.after($clone);
});

for removing the clone element.

$(".tr_clone_remove").live('click', function() { //Once remove button is clicked
    $(".newClass:last").remove(); //Remove field html
    x--; //Decrement field counter
});

html is as followinng

<tr class="tr_clone">
                       <!-- <td>1</td>-->
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span10" readonly>
                        <span><a href="javascript:void(0);" class="tr_clone_add" title="Add field"><span><i class="icon-plus-sign"></i></span></a> <a href="javascript:void(0);" class="tr_clone_remove" title="Remove field"><span style="color: #D63939;"><i class="icon-remove-sign"></i></span></a> </span> </td> </tr>

Here's another interesting, readable way to check if a string contains only digits.

This method works by splitting the string into an array using the spread operator, and then uses the every() method to test whether all elements (characters) in the array are included in the string of digits '0123456789':

const digits_only = string => [...string].every(c => '0123456789'.includes(c));_x000D_
_x000D_
console.log(digits_only('123')); // true_x000D_
console.log(digits_only('+123')); // false_x000D_
console.log(digits_only('-123')); // false_x000D_
console.log(digits_only('123.')); // false_x000D_
console.log(digits_only('.123')); // false_x000D_
console.log(digits_only('123.0')); // false_x000D_
console.log(digits_only('0.123')); // false_x000D_
console.log(digits_only('Hello, world!')); // false

Try changing the User that owns the service to Local System or use your admin account.

Under services, I changed the Service SQL Server (MSSQLSERVER) Log On from NT Service\Sql... To Local System. Right click the service and go to the Log On Tab and select the radio button Local System Account. You could also force another User to run it too if that fits better.

You're using JSTL 2.0 right? You don't need to put <c:out/> around all variables. Have you tried something like this?

<c:forEach items="${myParams.items}" var="currentItem" varStatus="stat">
  <c:set var="myVar" value="${myVar}${currentItem}" />
</c:forEach>

Edit: Beaten by the above

1 for month is February. The 30th of February is changed to 1st of March. You should set 0 for month. The best is to use the constant defined in Calendar:

c1.set(2000, Calendar.JANUARY, 30);

Use @ symbol before starting the string. like

string s = @"this is a really
long string
and this is 
the rest of it";

This is the solution, which is worked for me.

<p:commandButton id="b1" value="Save" process="userGroupSetupForm"
                    actionListener="#{userGroupSetupController.saveData()}" 
                    update="growl userGroupList userGroupSetupForm" />

Here, process="userGroupSetupForm" atrribute is mandatory for Ajax call. actionListener is calling a method from @ViewScope Bean. Also updating growl message, Datatable: userGroupList and Form: userGroupSetupForm.

Angular 4+: Use renderer.selectRootElement with a CSS selector to access the element.

I've got a form that initially displays an email input. After the email is entered, the form will be expanded to allow them to continue adding information relating to their project. However, if they are not an existing client, the form will include an address section above the project information section.

As of now, the data entry portion has not been broken up into components, so the sections are managed with *ngIf directives. I need to set focus on the project notes field if they are an existing client, or the first name field if they are new.

I tried the solutions with no success. However, Update 3 in this answer gave me half of the eventual solution. The other half came from MatteoNY's response in this thread. The result is this:

import { NgZone, Renderer } from '@angular/core';

constructor(private ngZone: NgZone, private renderer: Renderer) {}

setFocus(selector: string): void {
    this.ngZone.runOutsideAngular(() => {
        setTimeout(() => {
            this.renderer.selectRootElement(selector).focus();
        }, 0);
    });
}

submitEmail(email: string): void {
    // Verify existence of customer
    ...
    if (this.newCustomer) {
        this.setFocus('#firstname');
    } else {
        this.setFocus('#description');
    }
}

Since the only thing I'm doing is setting the focus on an element, I don't need to concern myself with change detection, so I can actually run the call to renderer.selectRootElement outside of Angular. Because I need to give the new sections time to render, the element section is wrapped in a timeout to allow the rendering threads time to catch up before the element selection is attempted. Once all that is setup, I can simply call the element using basic CSS selectors.

I know this example dealt primarily with the focus event, but it's hard for me that this couldn't be used in other contexts.

UPDATE: Angular dropped support for Renderer in Angular 4 and removed it completely in Angular 9. This solution should not be impacted by the migration to Renderer2. Please refer to this link for additional information: Renderer migration to Renderer2

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

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

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

def func():
    pass

func.temp = 1

print(func.__dict__)

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

print(TempClass.__dict__)

will output

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

If your input file has a fixed amount of columns separated by commas and you know in which columns are the strings it might be best to use the function

textscan()

Note that you can specify a format where you read up to a maximum number of characters in the string or until a delimiter (comma) is found.

Just add the display:block to the thead > tr and tbody. check the below example

http://www.imaputz.com/cssStuff/bigFourVersion.html

Had the same problem. found some videos on Youtube. So here is an even simpler suggestion. This is all the code you need:

#include <QDebug>

int main(int argc, char *argv[])  
{
   qDebug() <<"Hello World"<< endl;
   return 0;
}

The above code comes from Qt5 Tutorial: Building a simple Console application by

Dominique Thiebaut

When Modernizr runs, it removes the "no-js" class and replaces it with "js". This is a way to apply different CSS rules depending on whether or not Javascript support is enabled.

See Modernizer's source code.

Will take you to the master branch.

git checkout master

To switch to other branches do (ignore the square brackets, it's just for emphasis purposes)

git checkout [the name of the branch you want to switch to]

To create a new branch use the -b like this (ignore the square brackets, it's just for emphasis purposes)

git checkout -b [the name of the branch you want to create]

When you use @DataJpaTest you need to load classes using @Import explicitly. It wouldn't load you for auto.

The below programme will help you drop duplicates on whole , or if you want to drop duplicates based on certain columns , you can even do that:

import org.apache.spark.sql.SparkSession

object DropDuplicates {
def main(args: Array[String]) {
val spark =
  SparkSession.builder()
    .appName("DataFrame-DropDuplicates")
    .master("local[4]")
    .getOrCreate()

import spark.implicits._

// create an RDD of tuples with some data
val custs = Seq(
  (1, "Widget Co", 120000.00, 0.00, "AZ"),
  (2, "Acme Widgets", 410500.00, 500.00, "CA"),
  (3, "Widgetry", 410500.00, 200.00, "CA"),
  (4, "Widgets R Us", 410500.00, 0.0, "CA"),
  (3, "Widgetry", 410500.00, 200.00, "CA"),
  (5, "Ye Olde Widgete", 500.00, 0.0, "MA"),
  (6, "Widget Co", 12000.00, 10.00, "AZ")
)
val customerRows = spark.sparkContext.parallelize(custs, 4)

// convert RDD of tuples to DataFrame by supplying column names
val customerDF = customerRows.toDF("id", "name", "sales", "discount", "state")

println("*** Here's the whole DataFrame with duplicates")

customerDF.printSchema()

customerDF.show()

// drop fully identical rows
val withoutDuplicates = customerDF.dropDuplicates()

println("*** Now without duplicates")

withoutDuplicates.show()

// drop fully identical rows
val withoutPartials = customerDF.dropDuplicates(Seq("name", "state"))

println("*** Now without partial duplicates too")

withoutPartials.show()

 }
 }

I posted a similar question a couple months ago and think I've finally solved the problem. Follow the link at the bottom of my post if you just want to see the code.

The solution is to use an additional UIWindow.

When you want to display your UIAlertController:

1. Make your window the key and visible window (window.makeKeyAndVisible())
2. Just use a plain UIViewController instance as the rootViewController of the new window. (window.rootViewController = UIViewController())
3. Present your UIAlertController on your window's rootViewController

A couple things to note:

• Your UIWindow must be strongly referenced. If it's not strongly referenced it will never appear (because it is released). I recommend using a property, but I've also had success with an associated object.
• To ensure that the window appears above everything else (including system UIAlertControllers), I set the windowLevel. (window.windowLevel = UIWindowLevelAlert + 1)

Lastly, I have a completed implementation if you just want to look at that.

https://github.com/dbettermann/DBAlertController

According to your package.json, you're using Angular 8.3, but you've imported angular/cdk v9. You can downgrade your angular/cdk version or you can upgrade your Angular version to v9 by running:

ng update @angular/core @angular/cli

That will update your local angular version to 9. Then, just to sync material, run: ng update @angular/material

git add --all my/awesome/stuff/ works for me. [1]

1. https://git-scm.com/docs/git-add

You have to use bracket notation:

var obj = {};
obj[a[i]] = 0;
x.push(obj);

The result will be:

x = [{left: 0}, {top: 0}];

Maybe instead of an array of objects, you just want one object with two properties:

var x = {};

and

x[a[i]] = 0;

This will result in x = {left: 0, top: 0}.

As far as how to use unwind segues in StoryBoard...

Step 1)

Go to the code for the view controller that you wish to unwind to and add this:

Objective-C

- (IBAction)unwindToViewControllerNameHere:(UIStoryboardSegue *)segue {
    //nothing goes here
}

Be sure to also declare this method in your .h file in Obj-C

Swift

@IBAction func unwindToViewControllerNameHere(segue: UIStoryboardSegue) {
    //nothing goes here
}

Step 2)

In storyboard, go to the view that you want to unwind from and simply drag a segue from your button or whatever up to the little orange "EXIT" icon at the top right of your source view.

There should now be an option to connect to "- unwindToViewControllerNameHere"

That's it, your segue will unwind when your button is tapped.

If you are reencoding in your ffmpeg command line, that may be the reason why it is CPU intensive. You need to simply copy the streams to the single container. Since I do not have your command line I cannot suggest a specific improvement here. Your acodec and vcodec should be set to copy is all I can say.

EDIT: On seeing your command line and given you have already tried it, this is for the benefit of others who come across the same question. The command:

ffmpeg -i rtsp://@192.168.241.1:62156 -acodec copy -vcodec copy c:/abc.mp4

will not do transcoding and dump the file for you in an mp4. Of course this is assuming the streamed contents are compatible with an mp4 (which in all probability they are).

$('.tooltip').animate({ opacity: 1, top: "-10px" }, 'slow');

However, this doesn't appear to work on display: none elements (as fadeIn does). So, you might need to put this beforehand:

$('.tooltip').css('display', 'block');
$('.tooltip').animate({ opacity: 0 }, 0);

Inspired by @sdfor comment, here is a bash script that does the job

#!/bin/bash

printf "### Converting MySQL character set ###\n\n"

printf "Enter the encoding you want to set: "
read -r CHARSET

# Get the MySQL username
printf "Enter mysql username: "
read -r USERNAME

# Get the MySQL password
printf "Enter mysql password for user %s:" "$USERNAME"
read -rs PASSWORD

DBLIST=( mydatabase1 mydatabase2 )

printf "\n"


for DB in "${DBLIST[@]}"
do
(
    echo 'ALTER DATABASE `'"$DB"'` CHARACTER SET utf8 COLLATE `'"$CHARSET"'`;'
    mysql "$DB" -u"$USERNAME" -p"$PASSWORD" -e "SHOW TABLES" --batch --skip-column-names \
    | xargs -I{} echo 'ALTER TABLE `'{}'` CONVERT TO CHARACTER SET utf8 COLLATE `'"$CHARSET"'`;'
) \
| mysql "$DB" -u"$USERNAME" -p"$PASSWORD"

echo "$DB database done..."
done

echo "### DONE ###"
exit

Use DISTINCT to remove duplicate GROUPING SETS from the GROUP BY clause

In a completely silly example using GROUPING SETS() in general (or the special grouping sets ROLLUP() or CUBE() in particular), you could use DISTINCT in order to remove the duplicate values produced by the grouping sets again:

SELECT DISTINCT actors
FROM (VALUES('a'), ('a'), ('b'), ('b')) t(actors)
GROUP BY CUBE(actors, actors)

With DISTINCT:

actors
------
NULL
a
b

Without DISTINCT:

actors
------
a
b
NULL
a
b
a
b

But why, apart from making an academic point, would you do that?

Use DISTINCT to find unique aggregate function values

In a less far-fetched example, you might be interested in the DISTINCT aggregated values, such as, how many different duplicate numbers of actors are there?

SELECT DISTINCT COUNT(*)
FROM (VALUES('a'), ('a'), ('b'), ('b')) t(actors)
GROUP BY actors

Answer:

count
-----
2

Use DISTINCT to remove duplicates with more than one GROUP BY column

Another case, of course, is this one:

SELECT DISTINCT actors, COUNT(*)
FROM (VALUES('a', 1), ('a', 1), ('b', 1), ('b', 2)) t(actors, id)
GROUP BY actors, id

With DISTINCT:

actors  count
-------------
a       2
b       1

Without DISTINCT:

actors  count
-------------
a       2
b       1
b       1

For more details, I've written some blog posts, e.g. about GROUPING SETS and how they influence the GROUP BY operation, or about the logical order of SQL operations (as opposed to the lexical order of operations).

import os
current_file_path=os.path.dirname(os.path.realpath('__file__'))

if the database is InnoDB you dont need to do joins in deletion. only

DELETE FROM spawnlist WHERE spawnlist.type = "monster";

can be used to delete the all the records that linked with foreign keys in other tables, to do that you have to first linked your tables in design time.

CREATE TABLE IF NOT EXIST spawnlist (
  npc_templateid VARCHAR(20) NOT NULL PRIMARY KEY

)ENGINE=InnoDB;

CREATE TABLE IF NOT EXIST npc (
  idTemplate VARCHAR(20) NOT NULL,

  FOREIGN KEY (idTemplate) REFERENCES spawnlist(npc_templateid) ON DELETE CASCADE

)ENGINE=InnoDB;

if you uses MyISAM you can delete records joining like this

DELETE a,b
FROM `spawnlist` a
JOIN `npc` b
ON a.`npc_templateid` = b.`idTemplate`
WHERE a.`type` = 'monster';

in first line i have initialized the two temp tables for delet the record, in second line i have assigned the existance table to both a and b but here i have linked both tables together with join keyword, and i have matched the primary and foreign key for both tables that make link, in last line i have filtered the record by field to delete.

Using ls:

  ls -LR

from 'man ls':

   -L, --dereference
          when showing file information for a symbolic link, show informa-
          tion  for  the file the link references rather than for the link
          itself

Or, using find:

find -L .

From the find manpage:

-L     Follow symbolic links.

If you find you want to only follow a few symbolic links (like maybe just the toplevel ones you mentioned), you should look at the -H option, which only follows symlinks that you pass to it on the commandline.

Hiding navigation bar only on first page can be achieved through storyboard as well. On storyboard, goto Navigation Controller Scene->Navigation Bar. And select 'Hidden' property from the Attributes inspector. This will hide navigation bar starting from first viewcontroller until its made visible for the required viewcontroller.

Navigation bar can be set back to visible in ViewController's ViewWillAppear callback.

-(void)viewWillAppear:(BOOL)animated {

    [self.navigationController setNavigationBarHidden:YES animated:animated];
    [super viewWillAppear:animated];                                                  
}

Using the GSON library:

import com.google.gson.Gson;
import com.google.common.reflect.TypeToken;
import java.lang.reclect.Type;

Use the following code:

Type mapType = new TypeToken<Map<String, Map>>(){}.getType();  
Map<String, String[]> son = new Gson().fromJson(easyString, mapType);

Use ProcessBuilder to separate commands and arguments instead of spaces. This should work regardless of shell used:

import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

public class Test {

    public static void main(final String[] args) throws IOException, InterruptedException {
        //Build command 
        List<String> commands = new ArrayList<String>();
        commands.add("/bin/cat");
        //Add arguments
        commands.add("/home/narek/pk.txt");
        System.out.println(commands);

        //Run macro on target
        ProcessBuilder pb = new ProcessBuilder(commands);
        pb.directory(new File("/home/narek"));
        pb.redirectErrorStream(true);
        Process process = pb.start();

        //Read output
        StringBuilder out = new StringBuilder();
        BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line = null, previous = null;
        while ((line = br.readLine()) != null)
            if (!line.equals(previous)) {
                previous = line;
                out.append(line).append('\n');
                System.out.println(line);
            }

        //Check result
        if (process.waitFor() == 0) {
            System.out.println("Success!");
            System.exit(0);
        }

        //Abnormal termination: Log command parameters and output and throw ExecutionException
        System.err.println(commands);
        System.err.println(out.toString());
        System.exit(1);
    }
}

Another type of solution would be to autogenerate the nginx conf files via Jinja2 templates from ansible. The advantage of this is easy deployment to a cloud environment, and easy to replicate on multiple dev machines

let now = new Date();
let timestamp = now.getFullYear().toString();
let month = now.getMonth() + 1;
timestamp += (month < 10 ? '0' : '') + month.toString();
timestamp += (now.getDate() < 10 ? '0' : '') + now.getDate().toString();
timestamp += (now.getHours() < 10 ? '0' : '') + now.getHours().toString();
timestamp += (now.getMinutes() < 10 ? '0' : '') + now.getMinutes().toString();
timestamp += (now.getSeconds() < 10 ? '0' : '') + now.getSeconds().toString();
timestamp += (now.getMilliseconds() < 100 ? '0' : '') + now.getMilliseconds().toString();

You have the color you just need to convert it into the format you want.

Here's a script that should do the trick: http://www.phpied.com/rgb-color-parser-in-javascript/

Now there's the s (single line) modifier, that lets the dot matches new lines as well :) \s will also match new lines :D

Just add the s behind the slash

 /<pre.*?<\/pre>/gms

Jquery later allowed you to to find the parents with the .parents() method.

Hence I recommend using:

var $div = $('#divid').parents('div[class^="div-a"]');

This gives all parent nodes matching the selector. To get the first parent matching the selector use:

var $div = $('#divid').parents('div[class^="div-a"]').eq(0);

For other such DOM traversal queries, check out the documentation on traversing the DOM.

Since version v4.x you should use _.map:

_.map(users, 'id'); // [12, 14, 16, 18]

this way it is corresponds to native Array.prototype.map method where you would write (ES2015 syntax):

users.map(user => user.id); // [12, 14, 16, 18]

Before v4.x you could use _.pluck the same way:

_.pluck(users, 'id'); // [12, 14, 16, 18]

This does cause "funky characters":

System.out.println( "Mr. Foo".trim().replace('.','\0'));

produces:

Mr[] Foo

in my Eclipse console, where the [] is shown as a square box. As others have posted, use String.replace().

A list of HTTP Status Codes

The good-practice regarding status response is to, predictably, send the proper HTTP status code depending on the error (4xx for client errors, 5xx for server errors), regarding the actual JSON response there's no "bible" but a good idea could be to send (again) the status and data as 2 different properties of the root object in a successful response (this way you are giving the client the chance to capture the status from the HTTP headers and the payload itself) and a 3rd property explaining the error in a human-understandable way in the case of an error.

Stripe's API behaves similarly in the real world.

i.e.

OK

200, {status: 200, data: [...]}

Error

400, {status: 400, data: null, message: "You must send foo and bar to baz..."}

Canvas element doesn't support such characters as newline '\n', tab '\t' or < br /> tag.

Try it:

var newrow = mheight + 30;
ctx.fillStyle = "rgb(0, 0, 0)";
ctx.font = "bold 24px 'Verdana'";
ctx.textAlign = "center";
ctx.fillText("Game Over", mwidth, mheight); //first line
ctx.fillText("play again", mwidth, newrow); //second line 

or perhaps multiple lines:

var textArray = new Array('line2', 'line3', 'line4', 'line5');
var rows = 98;
ctx.fillStyle = "rgb(0, 0, 0)";
ctx.font = "bold 24px 'Verdana'";
ctx.textAlign = "center";
ctx.fillText("Game Over", mwidth, mheight); //first line

for(var i=0; i < textArray.length; ++i) {
rows += 30;
ctx.fillText(textArray[i], mwidth, rows); 
}  

I had the same issue on 14.04 with docker 1.9.1.

The upstart service command did work when I used sudo, even though I was root:

$ whoami
root
$ service docker status
status: Unbekannter Auftrag: docker

$ sudo service docker status
docker start/running, process 7394

It seems to depend on the environment variables.

service docker status works when becoming root with su -, but not when only using su:

$ su
Password:
$ service docker status
status: unknown job: docker
$ exit
$ su -
Password:
$ service docker status
docker start/running, process 2342

Yet another solution (Monday is the first day):

select 
    to_char(sysdate - to_char(sysdate, 'd') + 2, 'yyyymmdd') first_day_of_week
    , to_char(sysdate - to_char(sysdate, 'd') + 8, 'yyyymmdd') last_day_of_week
from
    dual

After snooping around all day, I figured out the answer thanks to this guide: http://piwigo.org/forum/viewtopic.php?id=15727

Basically under Eclipse -> Windows -> Preferences -> PHP Executables, there is a section on where the .exe and .ini is referenced. The defaulted ones were in the Eclipse directory when you install the PHP Development Tools SDK Feature from Eclipses Install New Software in the Help menu.

So instead of that, I added a new executable called PHP 5.3.5 (CGI) and referenced the cgi.exe and .ini from xampp's php folder.

Thank you webarto for giving your time to help me out.

How about you creat a batch file with the command you want, and call it with Process.Start

dir.bat content:

dir

then call:

Process.Start("dir.bat");

Will call the bat file and execute the dir

Use can use CSS too, add focus and active (for IE7 and under) to the hidden link. Example of a ul menu inside a div with class menu:

.menu ul ul {display:none; position:absolute; left:100%; top:0; padding:0;}
.menu ul ul ul {display:none; position:absolute; top:0; left:100%;}
.menu ul ul a, .menu ul ul a:focus, .menu ul ul a:active { width:170px; padding:4px 4%; background:#e77776; color:#fff; margin-left:-15px; }
.menu ul li:hover > ul { display:block; }
.menu ul li ul li {margin:0;}

It's late and untested, should work ;-)

if (charCode > 47 && charCode < 58) {
    document.getElementById("error").innerHTML = "*Please Enter Your Name Only";
    document.getElementById("fullname").focus();
    document.getElementById("fullname").style.borderColor = 'red';
    return false;
} else {
    document.getElementById("error").innerHTML = "";
    document.getElementById("fullname").style.borderColor = '';
    return true;
}

After checking out my branch in Egit, I switched to the Java View, then used File-->Import, Git-->Projects from Git, then selected the top level maven directory. This was with Eclipse Kepler.

This is not a permanent Fix for the problem but more like a workaround or hack

I had this very same issue when deploying my Angular App to gh-pages. First i was greeted with 404 messages when Refreshing my pages on gh-pages.

Then as what @gunter pointed out i started using HashLocationStrategy which was provided with Angular 2 .

But that came with it's own set of problems the # in the url it was really bad made the url look wierd like this https://rahulrsingh09.github.io/AngularConcepts/#/faq.

I started researching out about this problem and came across a blog. I tried giving it a shot and it worked .

Here is what i did as mentioned in that blog.

You’ll need to start by adding a 404.html file to your gh-pages repo that contains an empty HTML document inside it – but your document must total more than 512 bytes (explained below). Next put the following markup in your 404.html page’s head element:

<script>
  sessionStorage.redirect = location.href;
</script>
<meta http-equiv="refresh" content="0;URL='/REPO_NAME_HERE'"></meta>

This code sets the attempted entrance URL to a variable on the standard sessionStorage object and immediately redirects to your project’s index.html page using a meta refresh tag. If you’re doing a Github Organization site, don’t put a repo name in the content attribute replacer text, just do this: content="0;URL='/'"

In order to capture and restore the URL the user initially navigated to, you’ll need to add the following script tag to the head of your index.html page before any other JavaScript acts on the page’s current state:

<script>
  (function(){
    var redirect = sessionStorage.redirect;
    delete sessionStorage.redirect;
    if (redirect && redirect != location.href) {
      history.replaceState(null, null, redirect);
    }
  })();
</script>

This bit of JavaScript retrieves the URL we cached in sessionStorage over on the 404.html page and replaces the current history entry with it.

Reference backalleycoder Thanks to @Daniel for this workaround.

Now the above URL changes to https://rahulrsingh09.github.io/AngularConcepts/faq

var someParam = xxxxxxx;

commentbtn.click(function(){

    alert(someParam );
});

Using interactive rebase, you can place an amend command after each commit you want to alter. For instance:

pick a07cb86 Project tile template with full details and styling
x git commit --amend --reset-author -Chead

It's also possible that you have accidentally put the IDE into Full Screen Mode. On occasion, you may be inadertently pressing F11 to set FullScreen mode to On.

If this is the case, the Accepted Answer above will not work. Instead, you must disable Full Screen mode (View > Appearance > Full Screen).

Please see the attached screenshot.

You have empty $_POST. If your web-server wants see data in json-format you need to read the raw input and then parse it with JSON decode.

You need something like that:

$json = file_get_contents('php://input');
$obj = json_decode($json);

Also you have wrong code for testing JSON-communication...

CURLOPT_POSTFIELDS tells curl to encode your parameters as application/x-www-form-urlencoded. You need JSON-string here.

UPDATE

Your php code for test page should be like that:

$data_string = json_encode($data);

$ch = curl_init('http://webservice.local/');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: ' . strlen($data_string))
);

$result = curl_exec($ch);
$result = json_decode($result);
var_dump($result);

Also on your web-service page you should remove one of the lines header('Content-type: application/json');. It must be called only once.

Assuming employee numbers are in the first column and their names are in the second:

=VLOOKUP(A1, Sheet2!A:B, 2,false)

insert into TABLE_NAME
(COL1,COL2)
WITH
data AS
(
    select 'some value'    x from dual
    union all
    select 'another value' x from dual
)
SELECT my_seq.NEXTVAL, x 
FROM data
;

I think that is what you want, but i don't have access to oracle to test it right now.

You can use Console.WriteLine() to write out any native type. To see the output you must write console application (like in Java), then the output will be displayed in the Command Prompt, or if you are developing a windows GUI application, in Visual Studio you must turn on "Output" panel (under View) to see the commands output.

server.port = 8080 for custom 8080 port

I have tried to use the above robot there is a need to add a delay :( also you cannot debug or do something else because you lose the focus :(

//open upload window upload.click();

//put path to your image in a clipboard
StringSelection ss = new StringSelection(file.getAbsoluteFile());
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(ss, null);

//imitate mouse events like ENTER, CTRL+C, CTRL+V
Robot robot = new Robot();
robot.delay(250);
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_ENTER);
robot.delay(50);
robot.keyRelease(KeyEvent.VK_ENTER);

Cygwin uses a compatibility layer, while MinGW is native. That is one of the main differences.

Without using datetime object in python.

            self.y = y

# To store number of days in all months from 
# January to Dec. 
monthDays = [31, 28, 31, 30, 31, 30,
                                            31, 31, 30, 31, 30, 31 ]

# This function counts number of leap years

    # Since every leap year is of 366 days, 
    # Add a day for every leap year 
    n1 += countLeapYears(dt1)

    # SIMILARLY, COUNT TOTAL NUMBER OF DAYS BEFORE 'dt2' 

    n2 = dt2.y * 365 + dt2.d

was implemented that in service-now platform. No need to use other library - makepdf have all you need!

that my html part (include preloder gif):

   <div class="pdf-preview" ng-init="generatePDF(true)">
    <object data="{{c.content}}" type="application/pdf" style="width:58vh;height:88vh;" ng-if="c.content" ></object>
    <div ng-if="!c.content">
      <img src="https://support.lenovo.com/esv4/images/loading.gif" width="50" height="50">
    </div>
  </div>

this is client script (js part)

$scope.generatePDF = function (preview) {
    docDefinition = {} //you rootine to generate pdf content
    //...
    if (preview) {
        pdfMake.createPdf(docDefinition).getDataUrl(function(dataURL) {
            c.content = dataURL;
        });
    }
}

So on page load I fire init function that generate pdf content and if required preview (set as true) result will be assigned to c.content variable. On html side object will be not shown until c.content will got a value, so that will show loading gif.

Read this thread R - boolean operators && and ||.

Basically, the & is vectorized, i.e. it acts on each element of the comparison returning a logical array with the same dimension as the input. && is not, returning a single logical.

For Python users, you can try pyyaml-include.

Install

pip install pyyaml-include

Usage

import yaml
from yamlinclude import YamlIncludeConstructor

YamlIncludeConstructor.add_to_loader_class(loader_class=yaml.FullLoader, base_dir='/your/conf/dir')

with open('0.yaml') as f:
    data = yaml.load(f, Loader=yaml.FullLoader)

print(data)

Consider we have such YAML files:

+-- 0.yaml
+-- include.d
    +-- 1.yaml
    +-- 2.yaml

• 1.yaml 's content:

name: "1"

• 2.yaml 's content:

name: "2"

Include files by name

• On top level:

  If 0.yaml was:

!include include.d/1.yaml

We'll get:

{"name": "1"}

• In mapping:

  If 0.yaml was:

file1: !include include.d/1.yaml
file2: !include include.d/2.yaml

We'll get:

  file1:
    name: "1"
  file2:
    name: "2"

• In sequence:

  If 0.yaml was:

files:
  - !include include.d/1.yaml
  - !include include.d/2.yaml

We'll get:

files:
  - name: "1"
  - name: "2"

? Note:

File name can be either absolute (like /usr/conf/1.5/Make.yml) or relative (like ../../cfg/img.yml).

Include files by wildcards

File name can contain shell-style wildcards. Data loaded from the file(s) found by wildcards will be set in a sequence.

If 0.yaml was:

files: !include include.d/*.yaml

We'll get:

files:
  - name: "1"
  - name: "2"

? Note:

• For Python>=3.5, if recursive argument of !include YAML tag is true, the pattern “**” will match any files and zero or more directories and subdirectories.
• Using the “**” pattern in large directory trees may consume an inordinate amount of time because of recursive search.

In order to enable recursive argument, we shall write the !include tag in Mapping or Sequence mode:

• Arguments in Sequence mode:

!include [tests/data/include.d/**/*.yaml, true]

• Arguments in Mapping mode:

!include {pathname: tests/data/include.d/**/*.yaml, recursive: true}

Let the DOM load. To do something in the DOM you have to Load it first. In your case You have to load the <div> tag first. then you have something to modify. if you load the js first then that function is looking your HTML to do what you asked to do, but when that time your HTML is loading and your function cant find the HTML. So you can put the script in the bottom of the page. inside <body> tag then the function can access the <div> Because DOM is already loaded the time you hit the script.

Can you delete your bin debug folder and recompile again?

Or check your project reference to the System.Data.SQLite, track down where it is located, then open the dll in reflector. If you can't open it, that means that the dll is corrupted, you might want to find a correct one or reinstall the .net framework.

this may help

Response.Write("<script>");
Response.Write("window.open('../Inventory/pages/printableads.pdf', '_newtab');");
Response.Write("</script>");

Well, if the server sends a correct redirection header, the browser redirects and therefore "changes the url". It might be a browser issue, then. I don't know if it has anything to do with it, but you should not send a relative url in the location header ("HTTP/1.1 requires an absolute URI as argument to » Location: including the scheme, hostname and absolute path, but some clients accept relative URIs. ", http://php.net/manual/en/function.header.php), and "location" must be capitalized, like:

header('Location: http://myhost.com/mypage.php');

Yes, we can do this way.

import java.util.Scanner;

public class Collection_Basic {

    private static Scanner sc;

    public static void main(String[] args) {

        Object[] obj=new Object[4];
        sc = new Scanner(System.in);


        //Storing element
        System.out.println("enter your element");
        for(int i=0;i<4;i++){
            obj[i]=sc.nextInt();
        }

        /*
         * here, size reaches with its maximum capacity so u can not store more element,
         * 
         * for storing more element we have to create new array Object with required size
         */

        Object[] tempObj=new Object[10];

        //copying old array to new Array

        int oldArraySize=obj.length;
        int i=0;
        for(;i<oldArraySize;i++){

            tempObj[i]=obj[i];
        }

        /*
         * storing new element to the end of new Array objebt
         */
        tempObj[i]=90;

        //assigning new array Object refeence to the old one

        obj=tempObj;

        for(int j=0;j<obj.length;j++){
            System.out.println("obj["+j+"] -"+obj[j]);
        }
    }


}

Use a wild card selector * for this purpose.

#div * { /* Narrowing, to specific elements, like  input, textarea is PREFFERED */
 -webkit-user-select: none;  
  -moz-user-select: none;    
  -ms-user-select: none;      
  user-select: none;
}

Now, every element inside a div with id div will have no selection.

Demo

You want to use pyplot.grid:

x = numpy.arange(0, 1, 0.05)
y = numpy.power(x, 2)

fig = plt.figure()
ax = fig.gca()
ax.set_xticks(numpy.arange(0, 1, 0.1))
ax.set_yticks(numpy.arange(0, 1., 0.1))
plt.scatter(x, y)
plt.grid()
plt.show()

ax.xaxis.grid and ax.yaxis.grid can control grid lines properties.

Use: context.clearRect(0, 0, canvas.width, canvas.height);

This is the fastest and most descriptive way to clear the entire canvas.

Do not use: canvas.width = canvas.width;

Resetting canvas.width resets all canvas state (e.g. transformations, lineWidth, strokeStyle, etc.), it is very slow (compared to clearRect), it doesn't work in all browsers, and it doesn't describe what you are actually trying to do.

Dealing with transformed coordinates

If you have modified the transformation matrix (e.g. using scale, rotate, or translate) then context.clearRect(0,0,canvas.width,canvas.height) will likely not clear the entire visible portion of the canvas.

The solution? Reset the transformation matrix prior to clearing the canvas:

// Store the current transformation matrix
context.save();

// Use the identity matrix while clearing the canvas
context.setTransform(1, 0, 0, 1, 0, 0);
context.clearRect(0, 0, canvas.width, canvas.height);

// Restore the transform
context.restore();

Edit: I've just done some profiling and (in Chrome) it is about 10% faster to clear a 300x150 (default size) canvas without resetting the transform. As the size of your canvas increases this difference drops.

That is already relatively insignificant, but in most cases you will be drawing considerably more than you are clearing and I believe this performance difference be irrelevant.

100000 iterations averaged 10 times:
1885ms to clear
2112ms to reset and clear

jQuery has a built-in method for this:

$(window).resize(function () { /* do something */ });

For the sake of UI responsiveness, you might consider using a setTimeout to call your code only after some number of milliseconds, as shown in the following example, inspired by this:

function doSomething() {
    alert("I'm done resizing for the moment");
};

var resizeTimer;
$(window).resize(function() {
    clearTimeout(resizeTimer);
    resizeTimer = setTimeout(doSomething, 100);
});

This site uses the method isEmpty().

Edit: content grabbed from site, before the url will going to be invalid.

Worksheets("Sheet1").Range("A1").Sort _
    key1:=Worksheets("Sheet1").Range("A1")
Set currentCell = Worksheets("Sheet1").Range("A1")
Do While Not IsEmpty(currentCell)
    Set nextCell = currentCell.Offset(1, 0)
    If nextCell.Value = currentCell.Value Then
        currentCell.EntireRow.Delete
    End If
    Set currentCell = nextCell
Loop

In the first step the data in the first column from Sheet1 will be sort. In the second step, all rows with same data will be removed.

You could pass a Class<T> in.

private void foo(Class<?> cls) {
    if (cls == String.class) { ... }
    else if (cls == int.class) { ... }
}

private void bar() {
    foo(String.class);
}

Update: the OOP way depends on the functional requirement. Best bet would be an interface defining foo() and two concrete implementations implementing foo() and then just call foo() on the implementation you've at hand. Another way may be a Map<Class<?>, Action> which you could call by actions.get(cls). This is easily to be combined with an interface and concrete implementations: actions.get(cls).foo().

Within Excel you need to set a reference to the VB script run-time library. The relevant file is usually located at \Windows\System32\scrrun.dll

• To reference this file, load the Visual Basic Editor (ALT+F11)
• Select Tools > References from the drop-down menu
• A listbox of available references will be displayed
• Tick the check-box next to 'Microsoft Scripting Runtime'
• The full name and path of the scrrun.dll file will be displayed below the listbox
• Click on the OK button.

This can also be done directly in the code if access to the VBA object model has been enabled.

Access can be enabled by ticking the check-box Trust access to the VBA project object model found at File > Options > Trust Center > Trust Center Settings > Macro Settings

To add a reference:

Sub Add_Reference()

    Application.VBE.ActiveVBProject.References.AddFromFile "C:\Windows\System32\scrrun.dll"
'Add a reference

End Sub

To remove a reference:

Sub Remove_Reference()

Dim oReference As Object

    Set oReference = Application.VBE.ActiveVBProject.References.Item("Scripting")

    Application.VBE.ActiveVBProject.References.Remove oReference
'Remove a reference

End Sub

Or, if you are doing a split - join:

GROUP_CONCAT(split(thing, " "), '----') AS thing_name,

You may want to inclue WITHIN RECORD, like this:

GROUP_CONCAT(split(thing, " "), '----') WITHIN RECORD AS thing_name,

create dir platforms and copy qwindows.dll to it, platforms and app.exe are in the same dir

cd app_dir mkdir platforms xcopy qwindows.dll platforms\qwindows.dll

Folder structure + app.exe + platforms\qwindows.dll

The following command will clear only non-rooted buffers (main, system ..etc).

adb logcat -c

If you want to clear all the buffers (like radio, kernel..etc), Please use the following commands

adb root
adb logcat -b all -c

or

adb root
adb shell logcat -b all -c 

Use the following commands to know the list of buffers that device supports

adb logcat -g
adb logcat -b all -g
adb shell logcat -b all -g

I used Ctrl + F5 keyboard combination. By doing so, instead of reading from cache, I wanted to get a new response. The solution is to do hard refresh the page.

On MDN Web Docs:

"The HTTP 304 Not Modified client redirection response code indicates that there is no need to retransmit the requested resources. It is an implicit redirection to a cached resource."

With Docker v1.9 you can use the ARG instruction to fetch arguments passed by command line to the image on build action. Simply use the --build-arg flag. So you can avoid to keep explicit password (or other sensible information) on the Dockerfile and pass them on the fly.

source: https://docs.docker.com/engine/reference/commandline/build/ http://docs.docker.com/engine/reference/builder/#arg

Example:

Dockerfile

FROM busybox
ARG user
RUN echo "user is $user"

build image command

docker build --build-arg user=capuccino -t test_arguments -f path/to/dockerfile .

during the build it print

$ docker build --build-arg user=capuccino -t test_arguments -f ./test_args.Dockerfile .

fgets would work for you. here is very good documentation on this :-
http://www.cplusplus.com/reference/cstdio/fgets/

If you don't want to use fgets, following method will work for you :-

int readline(FILE *f, char *buffer, size_t len)
{
   char c; 
   int i;

   memset(buffer, 0, len);

   for (i = 0; i < len; i++)
   {   
      int c = fgetc(f); 

      if (!feof(f)) 
      {   
         if (c == '\r')
            buffer[i] = 0;
         else if (c == '\n')
         {   
            buffer[i] = 0;

            return i+1;
         }   
         else
            buffer[i] = c; 
      }   
      else
      {   
         //fprintf(stderr, "read_line(): recv returned %d\n", c);
         return -1; 
      }   
   }   

   return -1; 
}

Use this as your WHERE condition

WHERE CHARINDEX('Apples', column) = 0 

Using grep on the results of ps is a bad idea in a script, since some proportion of the time it will also match the grep process you've just invoked. The command pgrep avoids this problem, so if you need to know the process ID, that's a better option. (Note that, of course, there may be many processes matched.)

However, in your example, you could just use the similar command pkill to kill all matching processes:

pkill ruby

Incidentally, you should be aware that using -9 is overkill (ho ho) in almost every case - there's some useful advice about that in the text of the "Useless Use of kill -9 form letter ":

No no no. Don't use kill -9.

It doesn't give the process a chance to cleanly:

1. shut down socket connections
2. clean up temp files
3. inform its children that it is going away
4. reset its terminal characteristics

and so on and so on and so on.

Generally, send 15, and wait a second or two, and if that doesn't work, send 2, and if that doesn't work, send 1. If that doesn't, REMOVE THE BINARY because the program is badly behaved!

Don't use kill -9. Don't bring out the combine harvester just to tidy up the flower pot.

Two solutions for this error:

1. add this permission in your androidManifest.xml of your Android project

<uses-permission android:name="android.permission.INTERNET"/>

2. Turn on the Internet Connection of your device first.

Maybe you have to try this:

str = jQuery.parseJSON(str)

It might be the JavaScript check for some valid condition.
Two things you can perform a/c to your requirements:

1. either check for the valid string-input in the text-box.
2. or set a loop against that text box to enter the value until you post the form/request.

String barcode="0000000047166";

WebElement strLocator = driver.findElement(By.xpath("//*[@id='div-barcode']"));
strLocator.sendKeys(barcode);

A few comments:

import sun.misc.*; Don't do this. It is non-standard and not guaranteed to be the same between implementations. There are other libraries with Base64 conversion available.

byte[] encVal = c.doFinal(Data.getBytes()); You are relying on the default character encoding here. Always specify what character encoding you are using: byte[] encVal = c.doFinal(Data.getBytes("UTF-8")); Defaults might be different in different places.

As @thegrinner pointed out, you need to explicitly check the length of your byte arrays. If there is a discrepancy, then compare them byte by byte to see where the difference is creeping in.

The Git Parable explains how a typical DVCS gets created and why their creators did what they did. Also, you might want to take a look at Git for Computer Scientist; it explains what each type of object in Git does, including branches and tags.

The general practice is to have the central repository to which you push as a bare repo.

If you have SVN background, you can relate an SVN repo to a Git bare repo. It doesn't have the files in the repo in the original form. Whereas your local repo will have the files that form your "code" in addition.

You need to add a remote to the bare repo from your local repo and push your "code" to it.

It will be something like:

git remote add central <url> # url will be ssh based for you
git push --all central

I had this same issue with a project and some data files that I wasn't able to move inside the repo context for HIPAA reasons. I ended up using 2 Dockerfiles. One builds the main application without the stuff I needed outside the container and publishes that to internal repo. Then a second dockerfile pulls that image and adds the data and creates a new image which is then deployed and never stored anywhere. Not ideal, but it worked for my purposes of keeping sensitive information out of the repo.

Perhaps the shortest possible ways to evaluate an expression into "10" without digits are:

+!+[] + [+[]] // "10"

-~[] + [+[]] // "10"

//========== Explanation ==========\\

+!+[] : +[] Converts to 0. !0 converts to true. +true converts to 1. -~[] = -(-1) which is 1

[+[]] : +[] Converts to 0. [0] is an array with a single element 0.

Then JS evaluates the 1 + [0], thus Number + Array expression. Then the ECMA specification works: + operator converts both operands to a string by calling the toString()/valueOf() functions from the base Object prototype. It operates as an additive function if both operands of an expression are numbers only. The trick is that arrays easily convert their elements into a concatenated string representation.

Some examples:

1 + {} //    "1[object Object]"
1 + [] //    "1"
1 + new Date() //    "1Wed Jun 19 2013 12:13:25 GMT+0400 (Caucasus Standard Time)"

There's a nice exception that two Objects addition results in NaN:

[] + []   //    ""
[1] + [2] //    "12"
{} + {}   //    NaN
{a:1} + {b:2}     //    NaN
[1, {}] + [2, {}] //    "1,[object Object]2,[object Object]"

Just like leonbloy suggested, using two schemas in a database is the way to go. Suppose a source schema (old DB) and a target schema (new DB), you can try something like this (you should consider column names, types, etc.):

INSERT INTO target.Awards SELECT * FROM source.Nominations;

This answer works in SQL Server 2005, 2008, 2012.

At times the value has MANY single quotes. Rather than add a single quote next to each single quote as described above with 'John''s'. And there are examples using the REPLACE function to handle many single quotes in a value.

Try the following. This is an update statement but you can use it in an INSERT statement as well.

SET QUOTED_IDENTIFIER OFF

DECLARE @s VARCHAR(1000)

SET @s = "SiteId:'1'; Rvc:'6'; Chk:'1832'; TrEmp:'150'; WsId:'81'; TtlDue:'-9.40'; TtlDsc:'0'; TtlSvc:'0'; TtlTax:'-0.88'; TtlPay:'0'; TipAmt:'0.00'; SvcSeq:'09'; ReTx:'N'; TraceId:'160110124347N091832';"


UPDATE TransactionPaymentPrompt
set PromptData = @s

from TransactionPaymentPrompt tpp with (nolock)
where tpp.TransactionID = '106627343'

You can do that:

function formatAMPM(date) { // This is to display 12 hour format like you asked
  var hours = date.getHours();
  var minutes = date.getMinutes();
  var ampm = hours >= 12 ? 'pm' : 'am';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  minutes = minutes < 10 ? '0'+minutes : minutes;
  var strTime = hours + ':' + minutes + ' ' + ampm;
  return strTime;
}

var myDate = new Date();
var displayDate = myDate.getMonth()+ '/' +myDate.getDate()+ '/' +myDate.getFullYear()+ ' ' +formatAMPM(myDate);
console.log(displayDate);

Fiddle

Following command can be used to delete all the existing messages in kafka topic:

kafka-delete-records --bootstrap-server <kafka_server:port> --offset-json-file delete.json

The structure of the delete.json file should be following:

{ "partitions": [ { "topic": "foo", "partition": 1, "offset": -1 } ], "version": 1 }

where offset :-1 will delete all the records (This command has been tested with kafka 2.0.1

One difference is for r+ if the files does not exist, it'll not be created and open fails. But in case of a+ the file will be created if it does not exist.

Make your array a variable and use implode.

$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);

echo $comma_separated; // lastname,email,phone

http://php.net/manual/en/function.implode.php

Basically if the response header is text/html you need to parse, and if the response header is application/json it is already parsed for you.

Parsed data from jquery success handler for text/html response:

var parsed = JSON.parse(data);

Parsed data from jquery success handler for application/json response:

var parsed = data;

For those using ASP.NET MVC. You can use the following to force SSL/TLS over HTTPS over the whole site in two ways:

The Hard Way

1 - Add the RequireHttpsAttribute to the global filters:

GlobalFilters.Filters.Add(new RequireHttpsAttribute());

2 - Force Anti-Forgery tokens to use SSL/TLS:

AntiForgeryConfig.RequireSsl = true;

3 - Require Cookies to require HTTPS by default by changing the Web.config file:

<system.web>
    <httpCookies httpOnlyCookies="true" requireSSL="true" />
</system.web>

4 - Use the NWebSec.Owin NuGet package and add the following line of code to enable Strict Transport Security accross the site. Don't forget to add the Preload directive below and submit your site to the HSTS Preload site. More information here and here. Note that if you are not using OWIN, there is a Web.config method you can read up on on the NWebSec site.

// app is your OWIN IAppBuilder app in Startup.cs
app.UseHsts(options => options.MaxAge(days: 30).Preload());

5 - Use the NWebSec.Owin NuGet package and add the following line of code to enable Public Key Pinning (HPKP) across the site. More information here and here.

// app is your OWIN IAppBuilder app in Startup.cs
app.UseHpkp(options => options
    .Sha256Pins(
        "Base64 encoded SHA-256 hash of your first certificate e.g. cUPcTAZWKaASuYWhhneDttWpY3oBAkE3h2+soZS7sWs=",
        "Base64 encoded SHA-256 hash of your second backup certificate e.g. M8HztCzM3elUxkcjR2S5P4hhyBNf6lHkmjAHKhpGPWE=")
    .MaxAge(days: 30));

6 - Include the https scheme in any URL's used. Content Security Policy (CSP) HTTP header and Subresource Integrity (SRI) do not play nice when you imit the scheme in some browsers. It is better to be explicit about HTTPS. e.g.

<script src="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.4/bootstrap.min.js"></script>

The Easy Way

Use the ASP.NET MVC Boilerplate Visual Studio project template to generate a project with all of this and much more built in. You can also view the code on GitHub.

For Objective C:

submitButton.layer.cornerRadius = 5;
submitButton.clipsToBounds = YES;

For Swift:

submitButton.layer.cornerRadius = 5
submitButton.clipsToBounds = true

You can use:

Start-Process -FilePath "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" -ArgumentList "-verb:sync -source:dbfullsql="Data Source=mysource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;" -dest:dbfullsql="Data Source=.\mydestsource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;",computername=10.10.10.10,username=administrator,password=adminpass"

The key thing to note here is that FilePath must be in position 0, according to the Help Guide. To invoke the Help guide for a commandlet, just type in Get-Help <Commandlet-name> -Detailed . In this case, it is Get-Help Start-Process -Detailed.

To pass an object to a fragment, do the following:

First store the objects in Bundle, don't forget to put implements serializable in class.

            CategoryRowFragment fragment = new CategoryRowFragment();

            // pass arguments to fragment
            Bundle bundle = new Bundle();

            // event list we want to populate
            bundle.putSerializable("eventsList", eventsList);

            // the description of the row
            bundle.putSerializable("categoryRow", categoryRow);

            fragment.setArguments(bundle);

Then retrieve bundles in Fragment

       // events that will be populated in this row_x000D_
        mEventsList = (ArrayList<Event>)getArguments().getSerializable("eventsList");_x000D_
_x000D_
        // description of events to be populated in this row_x000D_
        mCategoryRow = (CategoryRow)getArguments().getSerializable("categoryRow");

There's a little bit more information about the semantics of these errors in RFC 2616, which documents HTTP 1.1.

Personally, I would probably use 400 Bad Request, but this is just my personal opinion without any factual support.

NB: If using a windows service to host the webservice.

You have to insure that your webservice is using the right Log on account to connect to SQL Server.

• Open services(I assume the windows service has been install)
• Right click on the service and goto properties.
• Click on "Log On" Tab
• Click on "This account" radio button
• Click "Browse"
• Enter Pc user name in Text Field and click "Check Name" Button to the right.
• Click on text in Text Field, press "OK" button
• enter login password and Apply

In C and C++ memory requirements of some variable :

signed char: -2^07 to +2^07-1
short: -2^15 to +2^15-1
int: -2^15 to +2^15-1
long: -2^31 to +2^31-1
long long: -2^63 to +2^63-1

signed char: -2^07 to +2^07-1
short: -2^15 to +2^15-1
int: -2^31 to +2^31-1
long: -2^31 to +2^31-1
long long: -2^63 to +2^63-1

depends on compiler and architecture of hardware

The international standard for the C language requires only that the size of short variables should be less than or equal to the size of type int, which in turn should be less than or equal to the size of type long.

With python 3.8+, we can do this with dataclass, and the asdict method that comes with it:

from dataclasses import dataclass, asdict

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker
from sqlalchemy import Column, String, Integer, create_engine

Base = declarative_base()
engine = create_engine('sqlite:///:memory:', echo=False)


@dataclass
class User(Base):
    __tablename__ = 'users'

    id: int = Column(Integer, primary_key=True)
    name: str = Column(String)
    email = Column(String)

    def __init__(self, name):
        self.name = name
        self.email = '[email protected]'


Base.metadata.create_all(engine)

SessionMaker = sessionmaker(bind=engine)
session = SessionMaker()

user1 = User("anurag")
session.add(user1)
session.commit()

query_result = session.query(User).one()  # type: User
print(f'{query_result.id=:}, {query_result.name=:}, {query_result.email=:}')
# query_result.id=1, query_result.name=anurag, [email protected]

query_result_dict = asdict(query_result)
print(query_result_dict)
# {'id': 1, 'name': 'anurag'}

The key is to use the @dataclass decorator, and annotate each column with its type (the : str part of the name: str = Column(String) line).

Also note that since the email is not annotated, it is not included in query_result_dict.

Here is a wget script in Python:

# From python cookbook, 2nd edition, page 487
import sys, urllib

def reporthook(a, b, c):
    print "% 3.1f%% of %d bytes\r" % (min(100, float(a * b) / c * 100), c),
for url in sys.argv[1:]:
    i = url.rfind("/")
    file = url[i+1:]
    print url, "->", file
    urllib.urlretrieve(url, file, reporthook)
print

To make the text portion of a ComboBox non-editable, set the DropDownStyle property to "DropDownList". The ComboBox is now essentially select-only for the user. You can do this in the Visual Studio designer, or in C# like this:

stateComboBox.DropDownStyle = ComboBoxStyle.DropDownList;

Link to the documentation for the ComboBox DropDownStyle property on MSDN.

Try this:

If Len(vValue & vbNullString) > 0 Then
  ' we have a non-Null and non-empty String value
  doSomething()
Else
  ' We have a Null or empty string value
  doSomethingElse()
End If

step1 :open xampp control panel

step 2: then click apache module config button.

step 3. after that you able to see some config file list.

step 4: then click the php.ini file.it will be open into default editor.

In my case, i found same error because there is version difference of node and npm on my local machine and defined in package.json version.

"engines": {
  "node": "0.8",
  "npm": "1.2.x"
}

when i check using

node --version : v0.10.41
npm --version : 1.4.29

when i update my package.json to

 "engines": {
  "node": "0.10.41",
  "npm": "1.4.29"
}

It works fine :)

You can use string.Format:

string template = "Hi We have these flights for you: {0}. Which one do you want";
string data = "A, B, C, D";
string message = string.Format(template, data);

You should load template from your resource file and data is your runtime values.

Be careful if you're translating to multiple languages, though: in some cases, you'll need different tokens (the {0}) in different languages.

I'd recommend these articles from "Games from Within, Indie Game Design And Programming":

• Physical Structure and C++ – Part 1: A First Look
• Physical Structure and C++ – Part 2: Build Times
• Even More Experiments with Includes
• How Incredible Is Incredibuild?
• The Care and Feeding of Pre-Compiled Headers

Granted, they are pretty old - you'll have to re-test everything with the latest versions (or versions available to you), to get realistic results. Either way, it is a good source for ideas.

SSL first connects to the host, so the host name and port number are transferred as clear text. When the host responds and the challenge succeeds, the client will encrypt the HTTP request with the actual URL (i.e. anything after the third slash) and and send it to the server.

There are several ways to break this security.

It is possible to configure a proxy to act as a "man in the middle". Basically, the browser sends the request to connect to the real server to the proxy. If the proxy is configured this way, it will connect via SSL to the real server but the browser will still talk to the proxy. So if an attacker can gain access of the proxy, he can see all the data that flows through it in clear text.

Your requests will also be visible in the browser history. Users might be tempted to bookmark the site. Some users have bookmark sync tools installed, so the password could end up on deli.ci.us or some other place.

Lastly, someone might have hacked your computer and installed a keyboard logger or a screen scraper (and a lot of Trojan Horse type viruses do). Since the password is visible directly on the screen (as opposed to "*" in a password dialog), this is another security hole.

Conclusion: When it comes to security, always rely on the beaten path. There is just too much that you don't know, won't think of and which will break your neck.

The easiest thing to do is to just change the permissions back. As @kroger noted git only tracks executable bits. So you probably just need to run chmod -x filename to fix it (or +x if that's what's needed.

you need to add Junit dependency in pom.xml file, it means you need to update with latest version.

<dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
        <scope>test</scope>
    </dependency> 

A gcc spec file can do the job, however all users on the machine will be affected.

My problem: Find indexes of list.

L = makelist() # Returns a list of different objects
La = np.array(L, dtype = object) # add dtype!
for c in chunks:
    L_ = La[c] # Since La is array, this works.

There is no default color. It means that every device can have own.

Joe Edel's answer to himself is actually the right approach to resolve the pivot problem.

Basically the idea is to list out the columns in the base table firstly, and then any number of options.value from the joint option table. Just left join the same option table multiple times in order to get all the options.

What needs to be done by the programming language is to build this query dynamically according to a list of options needs to be queried.

Here is yet another explanation of how the factorial calculation using recursion works.

Let's modify source code slightly:

int factorial(int n) {
      if (n <= 1)
            return 1;
      else
            return n * factorial(n - 1);
}

Here is calculation of 3! in details:

You can try the same with replacewith()

$('.click').click(function() {
    // get the contents of the link that was clicked
    var linkText = $(this).text();

    // replace the contents of the div with the link text
    $('#content-container').replaceWith(linkText);

    // cancel the default action of the link by returning false
    return false;
});

The .replaceWith() method removes content from the DOM and inserts new content in its place with a single call.

Here is a little utility function that collapses a named or unnamed list of values to a single string for easier printing. It will also print the code line itself. It's from my list examples in R page.

Generate some lists named or unnamed:

# Define Lists
ls_num <- list(1,2,3)
ls_str <- list('1','2','3')
ls_num_str <- list(1,2,'3')

# Named Lists
ar_st_names <- c('e1','e2','e3')
ls_num_str_named <- ls_num_str
names(ls_num_str_named) <- ar_st_names

# Add Element to Named List
ls_num_str_named$e4 <- 'this is added'

Here is the a function that will convert named or unnamed list to string:

ffi_lst2str <- function(ls_list, st_desc, bl_print=TRUE) {

  # string desc
  if(missing(st_desc)){
    st_desc <- deparse(substitute(ls_list))
  }

  # create string
  st_string_from_list = paste0(paste0(st_desc, ':'), 
                               paste(names(ls_list), ls_list, sep="=", collapse=";" ))

  if (bl_print){
    print(st_string_from_list)
  }
}

Testing the function with the lists created prior:

> ffi_lst2str(ls_num)
[1] "ls_num:=1;=2;=3"
> ffi_lst2str(ls_str)
[1] "ls_str:=1;=2;=3"
> ffi_lst2str(ls_num_str)
[1] "ls_num_str:=1;=2;=3"
> ffi_lst2str(ls_num_str_named)
[1] "ls_num_str_named:e1=1;e2=2;e3=3;e4=this is added"

Testing the function with subset of list elements:

> ffi_lst2str(ls_num_str_named[c('e2','e3','e4')])
[1] "ls_num_str_named[c(\"e2\", \"e3\", \"e4\")]:e2=2;e3=3;e4=this is added"
> ffi_lst2str(ls_num[2:3])
[1] "ls_num[2:3]:=2;=3"
> ffi_lst2str(ls_str[2:3])
[1] "ls_str[2:3]:=2;=3"
> ffi_lst2str(ls_num_str[2:4])
[1] "ls_num_str[2:4]:=2;=3;=NULL"
> ffi_lst2str(ls_num_str_named[c('e2','e3','e4')])
[1] "ls_num_str_named[c(\"e2\", \"e3\", \"e4\")]:e2=2;e3=3;e4=this is added"

Also, it is very likely, that problem with proxy settings.

Any who didn't overcome Tomact starting problrem, - try in NetBeans choose No Proxy in the Tools -> Options -> General tab.

It helped me.

The error message is fairly self-explanatory

(a,b,c,d,e) = line.split()

expects line.split() to yield 5 elements, but in your case, it is only yielding 1 element. This could be because the data is not in the format you expect, a rogue malformed line, or maybe an empty line - there's no way to know.

To see what line is causing the issue, you could add some debug statements like this:

if len(line.split()) != 11:
    print line

As Martin suggests, you might also be splitting on the wrong delimiter.

In my case the database had ran out of disk space. Which caused it to not respond. Once I cleared up that issue everything worked again.

Above mentioned issue happened in my local system. Check in sql server configuration manager.
Step 1:
SQL server Network configuration
step 2:

• Protocols for local server name
• Protocol name VIA Disabled or not..
• if not disabled , disable and check

.. after I made changes the sql server browser started working

This is, in effect, a way to check whether the expression e can be evaluated to be 0, and if not, to fail the build.

The macro is somewhat misnamed; it should be something more like BUILD_BUG_OR_ZERO, rather than ...ON_ZERO. (There have been occasional discussions about whether this is a confusing name.)

You should read the expression like this:

sizeof(struct { int: -!!(e); }))

1. (e): Compute expression e.

2. !!(e): Logically negate twice: 0 if e == 0; otherwise 1.

3. -!!(e): Numerically negate the expression from step 2: 0 if it was 0; otherwise -1.

4. struct{int: -!!(0);} --> struct{int: 0;}: If it was zero, then we declare a struct with an anonymous integer bitfield that has width zero. Everything is fine and we proceed as normal.

5. struct{int: -!!(1);} --> struct{int: -1;}: On the other hand, if it isn't zero, then it will be some negative number. Declaring any bitfield with negative width is a compilation error.

So we'll either wind up with a bitfield that has width 0 in a struct, which is fine, or a bitfield with negative width, which is a compilation error. Then we take sizeof that field, so we get a size_t with the appropriate width (which will be zero in the case where e is zero).

Some people have asked: Why not just use an assert?

keithmo's answer here has a good response:

These macros implement a compile-time test, while assert() is a run-time test.

Exactly right. You don't want to detect problems in your kernel at runtime that could have been caught earlier! It's a critical piece of the operating system. To whatever extent problems can be detected at compile time, so much the better.

The Java 8 streams API lacks the features of getting the index of a stream element as well as the ability to zip streams together. This is unfortunate, as it makes certain applications (like the LINQ challenges) more difficult than they would be otherwise.

There are often workarounds, however. Usually this can be done by "driving" the stream with an integer range, and taking advantage of the fact that the original elements are often in an array or in a collection accessible by index. For example, the Challenge 2 problem can be solved this way:

String[] names = {"Sam", "Pamela", "Dave", "Pascal", "Erik"};

List<String> nameList =
    IntStream.range(0, names.length)
        .filter(i -> names[i].length() <= i)
        .mapToObj(i -> names[i])
        .collect(toList());

As I mentioned above, this takes advantage of the fact that the data source (the names array) is directly indexable. If it weren't, this technique wouldn't work.

I'll admit that this doesn't satisfy the intent of Challenge 2. Nonetheless it does solve the problem reasonably effectively.

EDIT

My previous code example used flatMap to fuse the filter and map operations, but this was cumbersome and provided no advantage. I've updated the example per the comment from Holger.

What you want to use is this property:

dt.Columns[0].DataType

The DataType property will set to one of the following:

Boolean
Byte
Char
DateTime
Decimal
Double
Int16
Int32
Int64
SByte
Single
String
TimeSpan
UInt16
UInt32
UInt64

DataColumn.DataType Property MSDN Reference

You can always add the @Produces("application/json") above your web method or specify produces="application/json" to return json. Then on top of the Student class you can add @XmlRootElement from javax.xml.bind.annotation package.

Please note, it might not be a good idea to directly return model classes. Just a suggestion.

HTH.

There are some inconsistencies in how browsers expose the current window scrolling coordinates. Google Chrome on Mac and iOS seems to always return 0 when using document.documentElement.scrollTop or jQuery's $(window).scrollTop().

However, it works consistently with:

// horizontal scrolling amount
window.pageXOffset

// vertical scrolling amount
window.pageYOffset

function GetDateAndTime(dt) {
  var arr = new Array(dt.getDate(), dt.getMonth(), dt.getFullYear(),dt.getHours(),dt.getMinutes(),dt.getSeconds());

  for(var i=0;i<arr.length;i++) {
    if(arr[i].toString().length == 1) arr[i] = "0" + arr[i];
  }

  return arr[0] + "." + arr[1] + "." + arr[2] + " " + arr[3] + ":" + arr[4] + ":" + arr[5]; 
}

Time complexity with examples

1 - Basic Operations (arithmetic, comparisons, accessing array’s elements, assignment) : The running time is always constant O(1)

Example :

read(x)                               // O(1)
a = 10;                               // O(1)
a = 1.000.000.000.000.000.000         // O(1)

2 - If then else statement: Only taking the maximum running time from two or more possible statements.

Example:

age = read(x)                               // (1+1) = 2
if age < 17 then begin                      // 1
      status = "Not allowed!";              // 1
end else begin
      status = "Welcome! Please come in";   // 1
      visitors = visitors + 1;              // 1+1 = 2
end;

So, the complexity of the above pseudo code is T(n) = 2 + 1 + max(1, 1+2) = 6. Thus, its big oh is still constant T(n) = O(1).

3 - Looping (for, while, repeat): Running time for this statement is the number of looping multiplied by the number of operations inside that looping.

Example:

total = 0;                                  // 1
for i = 1 to n do begin                     // (1+1)*n = 2n
      total = total + i;                    // (1+1)*n = 2n
end;
writeln(total);                             // 1

So, its complexity is T(n) = 1+4n+1 = 4n + 2. Thus, T(n) = O(n).

4 - Nested Loop (looping inside looping): Since there is at least one looping inside the main looping, running time of this statement used O(n^2) or O(n^3).

Example:

for i = 1 to n do begin                     // (1+1)*n  = 2n
   for j = 1 to n do begin                  // (1+1)n*n = 2n^2
       x = x + 1;                           // (1+1)n*n = 2n^2
       print(x);                            // (n*n)    = n^2
   end;
end;

Common Running Time

There are some common running times when analyzing an algorithm:

1. O(1) – Constant Time Constant time means the running time is constant, it’s not affected by the input size.

2. O(n) – Linear Time When an algorithm accepts n input size, it would perform n operations as well.

3. O(log n) – Logarithmic Time Algorithm that has running time O(log n) is slight faster than O(n). Commonly, algorithm divides the problem into sub problems with the same size. Example: binary search algorithm, binary conversion algorithm.

4. O(n log n) – Linearithmic Time This running time is often found in "divide & conquer algorithms" which divide the problem into sub problems recursively and then merge them in n time. Example: Merge Sort algorithm.

5. O(n²) – Quadratic Time Look Bubble Sort algorithm!

6. O(n³) – Cubic Time It has the same principle with O(n²).

7. O(2ⁿ) – Exponential Time It is very slow as input get larger, if n = 1000.000, T(n) would be 21000.000. Brute Force algorithm has this running time.

8. O(n!) – Factorial Time THE SLOWEST !!! Example : Travel Salesman Problem (TSP)

Taken from this article. Very well explained should give a read.

Cheatsheet for running Gradle from the command line for Android Studio projects on Linux:

cd <project-root>
./gradlew
./gradlew tasks
./gradlew --help

Should get you started..

The following css statement disables click events

pointer-events:none;

Or you can have your alias in a HAVING clause

function urlExists($url=NULL)  
{  
    if($url == NULL) return false;  
    $ch = curl_init($url);  
    curl_setopt($ch, CURLOPT_TIMEOUT, 5);  
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  
    $data = curl_exec($ch);  
    $httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);  
    curl_close($ch);  
    if($httpcode>=200 && $httpcode<300){  
        return true;  
    } else {  
        return false;  
    }  
}  

This was grabbed from this post on how to check if a URL exists. Because Twitter should provide an error message above 300 when it is in maintenance, or a 404, this should work perfectly.

I had the same issue until i close teamviewer running on my pc. Then it worked fine!

It would be better to have a check before getting the string.

$newstring = substr($dynamicstring, -7);

if characters are greater then 7 return last 7 characters else return the provided string.

or do this if you need to return message or error if length is less then 7

$newstring = (strlen($dynamicstring)>7)?substr($dynamicstring, -7):"message";

This work for me hope this will help: to get radio selected value you have to use ratio name as selector like this

selectedVal = $('input[name="radio_name"]:checked').val();

selectedVal will have the required value, change the radio_name according to yours, in your case it would b "myradiobutton"

selectedVal = $('input[name="myradiobutton"]:checked').val();

If you make your parent element be "position: relative", then it will be the "offset parent" for the stuff you're tracking mouse events over. Thus the jQuery "position()" will be relative to that.

Make sure you have %JAVA_HOME% set by typing echo %JAVA_HOME% in Command Prompt. If you don't have that set, then you need to go add your Java path to Window's Environmental Variables.

An interface defines a set of methods that the implementing class must implement.

When a trait is use'd the implementations of the methods come along too--which doesn't happen in an Interface.

That is the biggest difference.

From the Horizontal Reuse for PHP RFC:

Traits is a mechanism for code reuse in single inheritance languages such as PHP. A Trait is intended to reduce some limitations of single inheritance by enabling a developer to reuse sets of methods freely in several independent classes living in different class hierarchies.

I would strongly suggest you start using jQuery. Your code would look like:

$(function() {
    $('form[name="myform"]').submit(function(e) {
        var username = $('form[name="myform"] input[name="username"]').val();
        if ( username == '') {
            e.preventDefault();
            $('#errors').text('*Please enter a username*');
        }
    });
});

    var Global = 'Global';

    function LocalToGlobalVariable() {

        // This creates a local variable.

        var Local = '5';

        // Doing this makes the variable available for one session
        // (a page refresh - it's the session not local)

        sessionStorage.LocalToGlobalVar = Local;

        // It can be named anything as long as the sessionStorage
        // references the local variable.
        // Otherwise it won't work.
        // This refreshes the page to make the variable take
        // effect instead of the last variable set.

        location.reload(false);
    };

    // This calls the variable outside of the function for whatever use you want.

    sessionStorage.LocalToGlobalVar;

I realize there is probably a lot of syntax errors in this but its the general idea... Thanks so much LayZee for pointing this out... You can find what a local and session Storage is at http://www.w3schools.com/html/html5_webstorage.asp. I have needed the same thing for my code and this was a really good idea.

private string ConvertTime(double miliSeconds)
{
    var timeSpan = TimeSpan.FromMilliseconds(totalMiliSeconds);
    // Converts the total miliseconds to the human readable time format
    return timeSpan.ToString(@"hh\:mm\:ss\:fff");
}

//Test

    [TestCase(1002, "00:00:01:002")]
    [TestCase(700011, "00:11:40:011")]
    [TestCase(113879834, "07:37:59:834")]
    public void ConvertTime_ResturnsCorrectString(double totalMiliSeconds, string expectedMessage)
    {
        // Arrange
        var obj = new Class();;

        // Act
        var resultMessage = obj.ConvertTime(totalMiliSeconds);

        // Assert
        Assert.AreEqual(expectedMessage, resultMessage);

UPDATE: TensorFlow supports Python 3.6 on Windows since version 1.2.0 (see the release notes)

TensorFlow only supports Python 3.5 64-bit as of now. Support for Python 3.6 is a work in progress and you can track it here as well as chime in the discussion.

The only alternative to use Python 3.6 with TensorFlow on Windows currently is building TF from source.

If you don't want to uninstall your Anaconda distribution for Python 3.6 and install a previous release you can create a conda environment for Python=3.5 as in: conda create --name tensorflow python=3.5 activate tensorflow pip install tensorflow-gpu
