Yes there is retainAll check out this

Set<Type> intersection = new HashSet<Type>(s1);
intersection.retainAll(s2);

You can use the methods:

CollectionUtils.containsAny and CollectionUtils.containsAll

from Apache Commons.

If Multiset extends from the Array class

x = [1, 1, 2, 4, 7]
y = [1, 2, 2, 2]
z = [1, 1, 3, 7]

UNION

x.union(y)           # => [1, 2, 4, 7]      (ONLY IN RUBY 2.6)
x.union(y, z)        # => [1, 2, 4, 7, 3]   (ONLY IN RUBY 2.6)
x | y                # => [1, 2, 4, 7]

DIFFERENCE

x.difference(y)      # => [4, 7] (ONLY IN RUBY 2.6)
x.difference(y, z)   # => [4] (ONLY IN RUBY 2.6)
x - y                # => [4, 7]

INTERSECTION

x & y                # => [1, 2]

For more info about the new methods in Ruby 2.6, you can check this blog post about its new features

Try using sets:

import sets
t = sets.Set(['a', 'b', 'c', 'd'])
t1 = sets.Set(['a', 'b', 'c'])

print t | t1
print t - t1

Using list comprehensions is a pretty obvious one for me. Not sure about performance, but at least things stay lists.

[x for x in a if x in b]

Or "all the x values that are in A, if the X value is in B".

The & operator takes the intersection of two sets.

{1, 2, 3} & {2, 3, 4}
Out[1]: {2, 3}

Use a combination of Array.prototype.filter and Array.prototype.includes:

const filteredArray = array1.filter(value => array2.includes(value));

For older browsers, with Array.prototype.indexOf and without an arrow function:

var filteredArray = array1.filter(function(n) {
    return array2.indexOf(n) !== -1;
});

NB! Both .includes and .indexOf internally compares elements in the array by using ===, so if the array contains objects it will only compare object references (not their content). If you want to specify your own comparison logic, use .some instead.

Simple copy & paste example with subqueries, Note, that both queries should return 1 row:

select
(select sum(items_1) from items_table_1 where ...)
-
(select count(items_2) from items_table_1 where ...) 

as difference

Not necessarily the most compact way of doing this, but quite clean IMO

if(json == null) {
    throw new BadThingException();
}
...

@ExceptionHandler(BadThingException.class)
@ResponseStatus(value = HttpStatus.BAD_REQUEST)
public @ResponseBody MyError handleException(BadThingException e) {
    return new MyError("That doesnt work");
}

Edit you can use @ResponseBody in the exception handler method if using Spring 3.1+, otherwise use a ModelAndView or something.

do while in an exit control loop. while is an entry control loop.

The notation that is used in

a[::-1]

means that for a given string/list/tuple, you can slice the said object using the format

<object_name>[<start_index>, <stop_index>, <step>]

This means that the object is going to slice every "step" index from the given start index, till the stop index (excluding the stop index) and return it to you.

In case the start index or stop index is missing, it takes up the default value as the start index and stop index of the given string/list/tuple. If the step is left blank, then it takes the default value of 1 i.e it goes through each index.

So,

a = '1234'
print a[::2]

would print

13

Now the indexing here and also the step count, support negative numbers. So, if you give a -1 index, it translates to len(a)-1 index. And if you give -x as the step count, then it would step every x'th value from the start index, till the stop index in the reverse direction. For example

a = '1234'
print a[3:0:-1]

This would return

432

Note, that it doesn't return 4321 because, the stop index is not included.

Now in your case,

str(int(a[::-1]))

would just reverse a given integer, that is stored in a string, and then convert it back to a string

i.e "1234" -> "4321" -> 4321 -> "4321"

If what you are trying to do is just reverse the given string, then simply a[::-1] would work .

I happened to be working in localhost , in windows 10, using WAMP, as it turns out, Wamp has a really accessible configuration interface to change the MySQL configuration. You just need to go to the Wamp panel, then to MySQL, then to settings and change the mode to sql-mode: none.(essentially disabling the strict mode) The following picture illustrates this.

Another alternative:

myPlanetsList.Select(i => i.Moons).Sum();

From lambda answer, I have made something closer to the requirements.

boolean imageCreated = false;

Bitmap bmp = null;
Marker currentLocationMarker;
private void doSomeCustomizationForMarker(LatLng currentLocation) {
    if (!imageCreated) {
        imageCreated = true;
        Bitmap.Config conf = Bitmap.Config.ARGB_8888;
        bmp = Bitmap.createBitmap(400, 400, conf);
        Canvas canvas1 = new Canvas(bmp);

        Paint color = new Paint();
        color.setTextSize(30);
        color.setColor(Color.WHITE);

        BitmapFactory.Options opt = new BitmapFactory.Options();
        opt.inMutable = true;

        Bitmap imageBitmap=BitmapFactory.decodeResource(getResources(),
                R.drawable.messi,opt);
        Bitmap resized = Bitmap.createScaledBitmap(imageBitmap, 320, 320, true);
        canvas1.drawBitmap(resized, 40, 40, color);

        canvas1.drawText("Le Messi", 30, 40, color);

        currentLocationMarker = mMap.addMarker(new MarkerOptions().position(currentLocation)
                .icon(BitmapDescriptorFactory.fromBitmap(bmp))
                // Specifies the anchor to be at a particular point in the marker image.
                .anchor(0.5f, 1));
    } else {
        currentLocationMarker.setPosition(currentLocation);
    }

}

I have faced the problem by placing a <div> inside <td>.

I was unable to identify the div using document.getElementById() if i place that inside td. But outside, it was working fine.

function sendAjaxRequest(element,urlToSend) {
             var clickedButton = element;
              $.ajax({type: "POST",
                  url: urlToSend,
                  data: { id: clickedButton.val(), access_token: $("#access_token").val() },
                  success:function(result){
                    alert('ok');
                  },
                 error:function(result)
                  {
                  alert('error');
                 }
             });
     }

       $(document).ready(function(){
          $("#button_1").click(function(e){
              e.preventDefault();
              sendAjaxRequest($(this),'/pages/test/');
          });

          $("#button_2").click(function(e){
              e.preventDefault();
              sendAjaxRequest($(this),'/pages/test/');
          });
        });

1. created as separate function for sending the ajax request.
2. Kept second parameter as URL because in future you want to send data to different URL

Try to run in another port like 3131. Run the command:

react-native run-android --port=3131

Looking for a table on a different database:

if exists (select * from MyOtherDatabase.sys.tables where name = 'MyTable')
    print 'Exists'

Actually ngAfterViewInit() will initiate only once when the component initiate.

If you really want a event triggers after the HTML element renter on the screen then you can use ngAfterViewChecked()

In the terminal: For Xcode 9.x and above

$ open /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app

For Xcode-beta 9.x and above

$ open /Applications/Xcode-beta.app/Contents/Developer/Applications/Simulator.app

Since it hasnt really been confirmed in an answer yet, Underscore's reduce also works for this.

_.reduce({ 
    a: {value:1}, 
    b: {value:2}, 
    c: {value:3} 
}, function(prev, current){
    //prev is either first object or total value
    var total = prev.value || prev

    return total + current.value
})

Note, _.reduce will return the only value (object or otherwise) if the list object only has one item, without calling iterator function.

_.reduce({ 
    a: {value:1} 
}, function(prev, current){
    //not called
})

//returns {value: 1} instead of 1

I don't know if I understand your question, but maybe:

foreach ($_POST as $id=>$value)
    if (strncmp($id,'id[',3) $info[rtrim(ltrim($id,'id['),']')]=$_POST[$id];

would help

That is if you really want to have a different name (id[key]) on each checkbox of the html form (not very efficient). If not you can just name them all the same, i.e. 'id' and iterate on the (selected) values of the array, like: foreach ($_POST['id'] as $key=>$value)...

Try this:

function pause(){
   read -p "$*"
}

If You want to check only when scroll ended, in Vanilla JS, You can come up with a solution like this:

Super Super compact

var t
window.onresize = () => { clearTimeout(t) t = setTimeout(() => { resEnded() }, 500) }
function resEnded() { console.log('ended') }

All 3 possible combinations together (ES6)

var t
window.onresize = () => {
    resizing(this, this.innerWidth, this.innerHeight) //1
    if (typeof t == 'undefined') resStarted() //2
    clearTimeout(t); t = setTimeout(() => { t = undefined; resEnded() }, 500) //3
}

function resizing(target, w, h) {
    console.log(`Youre resizing: width ${w} height ${h}`)
}    
function resStarted() { 
    console.log('Resize Started') 
}
function resEnded() { 
    console.log('Resize Ended') 
}

To input AN ENTIRE LINE containing lot of spaces you can use getline(cin,string_variable);

eg:

string input;
getline(cin, input);

This format captures all the spaces in the sentence untill return is pressed

The easiest way to strip all leading 0s is:

var s = "00test";
s = s.replace(/^0+/, "");

If just stripping a single leading 0 character, as the question implies, you could use

s = s.replace(/^0/, "");

You need to add your TextView in a ScrollView with something like this :

<ScrollView android:id="@+id/SCROLL_VIEW"  
android:layout_height="150px"   
android:layout_width="fill_parent">  

<TextView   
   android:id="@+id/TEXT_VIEW"   
   android:layout_height="wrap_content"   
   android:layout_width="wrap_content"   
   android:text="This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header" />  
 </ScrollView>

You can use my highlight plugin jQuiteLight, that can also work with regular expressions.

To install using npm type:

npm install jquitelight --save

To install using bower type:

bower install jquitelight 

Usage:

// for strings
$(".element").mark("query here");
// for RegExp
$(".element").mark(new RegExp(/query h[a-z]+/));

Assuming you know the size of your footer, you can do this:

    footer {
        position: sticky;
        height: 100px;
        top: calc( 100vh - 100px );
    }

public class TestModels
{
    public Dictionary<int, dynamic> sp = new Dictionary<int, dynamic>();

    public TestModels()
    {
        sp.Add(0, new {name="Test One", age=5});
        sp.Add(1, new {name="Test Two", age=7});
    }
}

The documentation says the following:

Microseconds (added in PHP 5.2.2). Note that date() will always generate 000000 since it takes an integer parameter, whereas DateTime::format() does support microseconds.

I.e., use DateTime instead.

The one liner : bind() to own address, connect() to remote address.

Quoting from the man page of bind()

bind() assigns the address specified by addr to the socket referred to by the file descriptor sockfd. addrlen specifies the size, in bytes, of the address structure pointed to by addr. Traditionally, this operation is called "assigning a name to a socket".

and, from the same for connect()

The connect() system call connects the socket referred to by the file descriptor sockfd to the address specified by addr.

To clarify,

• bind() associates the socket with its local address [that's why server side binds, so that clients can use that address to connect to server.]
• connect() is used to connect to a remote [server] address, that's why is client side, connect [read as: connect to server] is used.

On most (see details below) browsers, editing the placeholder in javascript allows multiline placeholder. As it has been said, it's not compliant with the specification and you shouldn't expect it to work in the future (edit: it does work).

This example replaces all multiline textarea's placeholder.

var textAreas = document.getElementsByTagName('textarea');

Array.prototype.forEach.call(textAreas, function(elem) {
    elem.placeholder = elem.placeholder.replace(/\\n/g, '\n');
});

<textarea class="textAreaMultiline" 
          placeholder="Hello, \nThis is multiline example \n\nHave Fun"
          rows="5" cols="35"></textarea>

Based on comments it seems some browser accepts this hack and others don't.
This is the results of tests I ran (with browsertshots and browserstack)

• Chrome: >= 35.0.1916.69
• Firefox: >= 35.0 (results varies on platform)
• IE: >= 10
• KHTML based browsers: 4.8
• Safari: No (tested = Safari 8.0.6 Mac OS X 10.8)
• Opera: No (tested <= 15.0.1147.72)

Fused with theses statistics, this means that it works on about 88.7% of currently (Oct 2015) used browsers.

Update: Today, it works on at least 94.4% of currently (July 2018) used browsers.

Simple:

if(pll_current_language() == 'en'){

It's not well advertised, but git clean is really handy. Git Ready has a nice introduction to git clean.

I actually got this error because I was checking InnerHtml for some content that was generated dynamically - i.e. a control that is runat=server.

To solve this I had to remove the "static" keyword on my method, and it ran fine.

if you are using mac, proceed with following steps:

1. Move to following directory:

   /sts-bundle/STS.app/Contents/Eclipse
   

2. Add the java home explicitly in STS.ini file:

   -vm
   /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/bin
   -vmargs
   

Make sure not to add all the statements in single line

Just use PrintJS

let printjs = document.createElement("script");
printjs.src = "https://printjs-4de6.kxcdn.com/print.min.js";
document.body.appendChild(printjs);

printjs.onload = function (){
    printJS('id_of_div_you_want_to_print', 'html');
}

Try using

<table  border="1" cellspacing="0" cellpadding="0" class="template-table" 
style="table-layout: fixed; width: 100%"> 

as table style along with

<td style="word-break:break-word">long text</td>

for td it works for normal/real scenario text with words, not for random typed letters without gaps

Your String resource

<resources>
   <string name="your_string_resource_name">This is normal text<![CDATA[<b> but this is bold </b>]]> and <![CDATA[<u> but this is underline text</u>]]></string>
</resources> 

your java class

yourtextView.setText(getString(R.string.your_string_resource_name));

For those who don't want any plugin or other stuffs, We can use the document.styleSheets to disable/enable the css.

// code to disable all the css

for (const item in document.styleSheets) {
  document.styleSheets[item].disabled=true;
}

If you use chrome, you can create a function and add to your snippets. So that you can use the console to enable/disable the css for any sites.

// Snippets -> DisableCSS

function disableCss(value = true){
  for (const item in document.styleSheets) {
    document.styleSheets[item].disabled=value;
  }  
}

// in console

disableCss() // by default is disable
disableCss(false) // to enable

To solve this problem (RPC:S-5:AEC-0):

1. Go to settings
2. Go to backup and reset
3. Go down to recovery mode
4. Reboot the system

This seemed to fix the problem for my tab. Now I can use Google Play store and download any app I want.

Using OnPaint to draw a custom border on your controls is fine. But know how to use OnPaint to keep efficiency up, and render time to a minimum. Read this if you are experiencing a laggy GUI while using custom paint routines: What is the right way to use OnPaint in .Net applications?

Because the accepted answer of PraVn may seem simple, but is actually inefficient. Using a custom control, like the ones posted in the answers above is way better.

Maybe the performance is not an issue in your application, because it is small, but for larger applications with a lot of custom OnPaint routines it is a wrong approach to use the way PraVn showed.

There are static libraries (LIB) and dynamic libraries (DLL) - but note that .LIB files can be either static libraries (containing object files) or import libraries (containing symbols to allow the linker to link to a DLL).

Libraries are used because you may have code that you want to use in many programs. For example if you write a function that counts the number of characters in a string, that function will be useful in lots of programs. Once you get that function working correctly you don't want to have to recompile the code every time you use it, so you put the executable code for that function in a library, and the linker can extract and insert the compiled code into your program. Static libraries are sometimes called 'archives' for this reason.

Dynamic libraries take this one step further. It seems wasteful to have multiple copies of the library functions taking up space in each of the programs. Why can't they all share one copy of the function? This is what dynamic libraries are for. Rather than building the library code into your program when it is compiled, it can be run by mapping it into your program as it is loaded into memory. Multiple programs running at the same time that use the same functions can all share one copy, saving memory. In fact, you can load dynamic libraries only as needed, depending on the path through your code. No point in having the printer routines taking up memory if you aren't doing any printing. On the other hand, this means you have to have a copy of the dynamic library installed on every machine your program runs on. This creates its own set of problems.

As an example, almost every program written in 'C' will need functions from a library called the 'C runtime library, though few programs will need all of the functions. The C runtime comes in both static and dynamic versions, so you can determine which version your program uses depending on particular needs.

Why does this happen? When you install a fresh copy of linux, gcc compiler comes pre-packed with it. It only contains the files and binaries which are used to run the linux(to save space and time, obviously).

How to solve this error? All you need is to update your packages through the package manager and reinstall the build-essential packages. The commands might be different on different kernels.

Simple way which i found is,

In servlet:

You can set the value and forward it to JSP like below

req.setAttribute("myname",login);
req.getRequestDispatcher("welcome.jsp").forward(req, resp); 

In Welcome.jsp you can get the values by

.<%String name = (String)request.getAttribute("myname"); %>
<%= name%>

(or) directly u can call

<%= request.getAttribute("myname") %>.

It may be too late but for the sake of others who have the same problem, to set the height of the ImageView:

imageView.getLayoutParams().height = 20;

Important. If you're setting the height after the layout has already been 'laid out', make sure you also call:

imageView.requestLayout();

To change the labels for Pandas df.plot() use ax.legend([...]):

import pandas as pd
import matplotlib.pyplot as plt

fig, ax = plt.subplots()
df = pd.DataFrame({'A':26, 'B':20}, index=['N'])
df.plot(kind='bar', ax=ax)
#ax = df.plot(kind='bar') # "same" as above
ax.legend(["AAA", "BBB"]);

Another approach is to do the same by plt.legend([...]):

import matplotlib.pyplot as plt
df.plot(kind='bar')
plt.legend(["AAA", "BBB"]);

This one

<script type="text/javascript">var s = '/Controller/Action#11112';if(typeof s == 'string' && /\?*/.test(s)){s = s.replace(/\#.*/gi,'');}document.write(s);</script>

It's more common answer. And can be use with s= document.location.href;

My app gets installed on client web servers. Rather than fiddling with Network Service permissions and the registry, I opted to check SourceExists and run CreateEventSource in my installer.

I also added a try/catch around log.source = "xx" in the app to set it to a known source if my event source wasn't created (This would only come up if I hot swapped a .dll instead of re-installing).

I suspect ^ doesn't work the way you think it does outside of a character class.

What you're telling it to do is replace everything that isn't an alphanumeric with an empty string, OR any leading space. I think what you mean to say is that spaces are ok to not replace - try moving the \s into the [] class.

in my case this error resolved by adding permission level to root folder .

i previously only granted permission in 2 place. one in site setting and one in a new folder that has custom permission .

but the user permission to browse the root folder was also required. Note The "Folder setting" in root folder

another time i had similar problem and adding users in the following windows group SQLServerReportServerUser$servername$MSRS10_50.MSSQLSERVER and running IE as Administrator or turning off UAC resolved my problem .

Just create an element by parsing it with jQuery.

<div id="someElement"></div>
<script>
    var code = "<script>alert(123);<\/script>";
    $("#someElement").append($(code));
</script>

Working example: https://plnkr.co/edit/V2FE28Q2eBrJoJ6PUEBz

<div id="google_translate_element"></div><script type="text/javascript">
function googleTranslateElementInit() {
  new google.translate.TranslateElement({pageLanguage: 'en', includedLanguages: 'ar', layout: google.translate.TranslateElement.InlineLayout.SIMPLE}, 'google_translate_element');
}
</script><script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>

For a good quality x264 encoding of 1060i, done by a computer, not a mobile device, not in real time, you could use a bitrate at about 5 MBps. That means 2250 MB/hour of encoded material. Recommend you deinterlace the footage and compress as progressive.

let d=d1-d2;echo $d;

This should help.

I was suffering the same issue. danorton's 'toggling display' fix did work for me when added to the step function of my animation but I was concerned about performance and I looked for other options.

In my circumstance the element which wasn't repainting was within an absolutely position element which did not, at the time, have a z-index. Adding a z-index to this element changed the behaviour of Chrome and repaints happened as expected -> animations became smooth.

I doubt that this is a panacea, I imagine it depends why Chrome has chosen not to redraw the element but I'm posting this specific solution here in the help it hopes someone.

Cheers, Rob

tl;dr >> Try adding a z-index to the element or a parent thereof.

You can also use HTML5 replaceState if you want to change the url but don't want to add the entry to the browser history:

if (window.history.replaceState) {
   //prevents browser from storing history with each change:
   window.history.replaceState(statedata, title, url);
}

This would 'break' the back button functionality. This may be required in some instances such as an image gallery (where you want the back button to return back to the gallery index page instead of moving back through each and every image you viewed) whilst giving each image its own unique url.

in the iframe tag, you can easily add width='100%' instead of the preset value giving to you by the map

like this:

 <iframe src="https://www.google.com/maps/embed?anyLocation" width="100%" height="400" frameborder="0" style="border:0;" allowfullscreen=""></iframe>

mkdir()

creates only one directory at a time, if it is parent that one only. other wise it can create the sub directory(if the specified path is existed only) and do not create any directories in between any two directories. so it can not create smultiple directories in one directory

mkdirs()

create the multiple directories(in between two directories also) at a time.

Use the write()-Method of the Popup's document to put your markup there:

$.post(url, function (data) {
    var w = window.open('about:blank');
    w.document.open();
    w.document.write(data);
    w.document.close();
});

It means that the http server at cw.na1.hgncloud.com send some http headers to tell web browsers like Chrome to allow iframe loading of that page (https://cw.na1.hgncloud.com/crossmatch/) only from a page hosted on the same domain (cw.na1.hgncloud.com) :

Content-Security-Policy: frame-ancestors 'self' https://cw.na1.hgncloud.com
X-Frame-Options: ALLOW-FROM https://cw.na1.hgncloud.com

You should read that :

• https://developer.mozilla.org/en-US/docs/Web/Security/CSP
• https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy

You were close. You can do:

var element = $("#parentDiv").find(".myClassNameOfInterest");

• .find() - http://api.jquery.com/find

Alternatively, you can do:

var element = $(".myClassNameOfInterest", "#parentDiv");

...which sets the context of the jQuery object to the #parentDiv.

EDIT:

Additionally, it may be faster in some browsers if you do div.myClassNameOfInterest instead of just .myClassNameOfInterest.

Update

If your popover is going to have a selector that is consistent then you can make use of selector property of popover constructor.

var popOverSettings = {
    placement: 'bottom',
    container: 'body',
    html: true,
    selector: '[rel="popover"]', //Sepcify the selector here
    content: function () {
        return $('#popover-content').html();
    }
}

$('body').popover(popOverSettings);

Demo

Other ways:

1. (Standard Way) Bind the popover again to the new items being inserted. Save the popoversettings in an external variable.
2. Use Mutation Event/Mutation Observer to identify if a particular element has been inserted on to the ul or an element.

Source

var popOverSettings = { //Save the setting for later use as well
    placement: 'bottom',
    container: 'body',
    html: true,
    //content:" <div style='color:red'>This is your div content</div>"
    content: function () {
        return $('#popover-content').html();
    }

}

$('ul').on('DOMNodeInserted', function () { //listed for new items inserted onto ul
    $(event.target).popover(popOverSettings);
});

$("button[rel=popover]").popover(popOverSettings);
$('.pop-Add').click(function () {
    $('ul').append("<li class='project-name'>     <a>project name 2        <button class='pop-function' rel='popover'></button>     </a>   </li>");
});

But it is not recommended to use DOMNodeInserted Mutation Event for performance issues as well as support. This has been deprecated as well. So your best bet would be to save the setting and bind after you update with new element.

Demo

Another recommended way is to use MutationObserver instead of MutationEvent according to MDN, but again support in some browsers are unknown and performance a concern.

MutationObserver = window.MutationObserver || window.WebKitMutationObserver;
// create an observer instance
var observer = new MutationObserver(function (mutations) {
    mutations.forEach(function (mutation) {
        $(mutation.addedNodes).popover(popOverSettings);
    });
});

// configuration of the observer:
var config = {
     attributes: true, 
     childList: true, 
     characterData: true
};

// pass in the target node, as well as the observer options
observer.observe($('ul')[0], config);

Demo

Sounds like you're looking for a Here document

As noted in a prior answer, although git merge-base works,

$ git merge-base myfeature develop
050dc022f3a65bdc78d97e2b1ac9b595a924c3f2

If myfeature is the current branch, as is common, you can use --fork-point:

$ git merge-base --fork-point develop
050dc022f3a65bdc78d97e2b1ac9b595a924c3f2

This argument works only in sufficiently recent versions of git. Unfortunately it doesn't always work, however, and it is not clear why. Please refer to the limitations noted toward the end of this answer.

For full commit info, consider:

$ git log -1 $(git merge-base --fork-point develop)

There is an article about your question on asp.net's website. I hope it can help you.

How to call an api with asp net

http://www.asp.net/web-api/overview/advanced/calling-a-web-api-from-a-net-client

Here is a small part from the POST section of the article

The following code sends a POST request that contains a Product instance in JSON format:

// HTTP POST
var gizmo = new Product() { Name = "Gizmo", Price = 100, Category = "Widget" };
response = await client.PostAsJsonAsync("api/products", gizmo);
if (response.IsSuccessStatusCode)
{
    // Get the URI of the created resource.
    Uri gizmoUrl = response.Headers.Location;
}

This is what I do when I need Initialized Global Constants:
1. Add a module called Globals
2. Add Properties like this into the Globals module:

Property Get PSIStartRow() As Integer  
    PSIStartRow = Sheets("FOB Prices").Range("F1").Value  
End Property  
Property Get PSIStartCell() As String  
    PSIStartCell = "B" & PSIStartRow  
End Property

You can also use

<input type="button" value = "Refresh" onclick="history.go(0)" />

It works fine for me.

./gradlew

Your directory with gradlew is not included in the PATH, so you must specify path to the gradlew. . means "current directory".

A slightly tongue-in-cheek answer; write the statement

array = initial_value

in your favourite array-capable language (mine is Fortran, but there are many others), and link it to your C code. You'd probably want to wrap it up to be an external function.

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

Chrome may block document.write that inserts a script in certain cases. When this happens, it will display this warning in the console:

A Parser-blocking, cross-origin script, ..., is invoked via document.write. This may be blocked by the browser if the device has poor network connectivity.

It is due permission problem,

sudo chown -R $USER /path to your python installed directory

default it would be /usr/local/lib/python2.7/

or try,

pip install --user -r package_name

and then say, pip install -r requirements.txt this will install inside your env

dont say, sudo pip install -r requirements.txt this is will install into arbitrary python path.

Here's my solution, just pass in a parseable date:

function getAge(birth) {
  ageMS = Date.parse(Date()) - Date.parse(birth);
  age = new Date();
  age.setTime(ageMS);
  ageYear = age.getFullYear() - 1970;

  return ageYear;

  // ageMonth = age.getMonth(); // Accurate calculation of the month part of the age
  // ageDay = age.getDate();    // Approximate calculation of the day part of the age
}

Another option is

Private Sub Worksheet_Change(ByVal Target As Range)
    IF Target.Address = "$D$2" Then
        MsgBox("Cell D2 Has Changed.")
    End If
End Sub

I believe this uses fewer resources than Intersect, which will be helpful if your worksheet changes a lot.

I usually define an nvl function, and put it in globals and filters.

def nvl(*args):
    for item in args:
        if item is not None:
            return item
    return None

app.jinja_env.globals['nvl'] = nvl
app.jinja_env.filters['nvl'] = nvl

Usage in a template:

<span>Welcome {{ nvl(person.nick, person.name, 'Anonymous') }}<span>

// or 

<span>Welcome {{ person.nick | nvl(person.name, 'Anonymous') }}<span>

I had a same issue on ubuntu 14.04 Here is a solution

i have solve this problem several times using the same steps :

1- Close Eclipse.

2- Restart your phone.

3- End adb.exe process in Task Manager (Windows). In Mac, force close in Activity Monitor.

4- Issue kill and start command in \platform-tools\

C:\sdk\platform-tools>adb kill-server

C:\sdk\platform-tools>adb start-server

5- If it says something like 'started successfully', you are good.

but now it's doesn't work cause i have an anti-virus called "Baidu", this program have run "Baidu ADB server", finally i turn this process off and retry above steps it's work properly.

Since you are explicitly also asking to handle columns that haven't yet been filled out, and I assume also don't want to mess with them if they have a word instead of a number, you might consider this:

=If(IsNumber(K23), If(K23 > 0, ........., 0), 0)

This just says... If K23 is a number; And if that number is greater than zero; Then do something ......... Otherwise, return zero.

In ........., you might put your division equation there, such as A1/K23, and you can rest assured that K23 is a number which is greater than zero.

The problem is here:

answer = newList.sort()

sort does not return the sorted list; rather, it sorts the list in place.

Use:

answer = sorted(newList)

With PostgreSQL you can do it via the RETURNING keyword:

PostgresSQL - RETURNING

INSERT INTO mytable( field_1, field_2,... )
VALUES ( value_1, value_2 ) RETURNING anyfield

It will return the value of "anyfield". "anyfield" may be a sequence or not.

To use it with JDBC, do:

ResultSet rs = statement.executeQuery("INSERT ... RETURNING ID");
rs.next();
rs.getInt(1);

While you should generally prefer sys.exit because it is more "friendly" to other code, all it actually does is raise an exception.

If you are sure that you need to exit a process immediately, and you might be inside of some exception handler which would catch SystemExit, there is another function - os._exit - which terminates immediately at the C level and does not perform any of the normal tear-down of the interpreter; for example, hooks registered with the "atexit" module are not executed.

Nothing worked for me. All I was seeing was the HTML of the login page, coming back to the client side with code 200. (302 at first but the same Ajax request loading login page inside another Ajax request, which was supposed to be a redirect rather than loading plain text of the login page).

In the login controller, I added this line:

Response.Headers["land"] = "login";

And in the global Ajax handler, I did this:

$(function () {
    var $document = $(document);
    $document.ajaxSuccess(function (e, response, request) {
        var land = response.getResponseHeader('land');
        var redrUrl = '/login?ReturnUrl=' + encodeURIComponent(window.location);
        if(land) {
            if (land.toString() === 'login') {
                window.location = redrUrl;
            }
        }
    });
});

Now I don't have any issue, and it works like a charm.

You should use partial views. I use the following approach:

Use a view model so you're not passing your domain models to your views:

public class EditPersonViewModel
{
    public int Id { get; set; }   // this is only used to retrieve record from Db
    public string Name { get; set; }
    public string Age { get; set; }
}

In your PersonController:

[HttpGet] // this action result returns the partial containing the modal
public ActionResult EditPerson(int id)
{  
    var viewModel = new EditPersonViewModel();
    viewModel.Id = id;
    return PartialView("_EditPersonPartial", viewModel);
}

[HttpPost] // this action takes the viewModel from the modal
public ActionResult EditPerson(EditPersonViewModel viewModel)
{
    if (ModelState.IsValid)
    {
        var toUpdate = personRepo.Find(viewModel.Id);
        toUpdate.Name = viewModel.Name;
        toUpdate.Age = viewModel.Age;
        personRepo.InsertOrUpdate(toUpdate);
        personRepo.Save();
        return View("Index");
    }
}

Next create a partial view called _EditPersonPartial. This contains the modal header, body and footer. It also contains the Ajax form. It's strongly typed and takes in our view model.

@model Namespace.ViewModels.EditPersonViewModel
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
    <h3 id="myModalLabel">Edit group member</h3>
</div>
<div>
@using (Ajax.BeginForm("EditPerson", "Person", FormMethod.Post,
                    new AjaxOptions
                    {
                        InsertionMode = InsertionMode.Replace,
                        HttpMethod = "POST",
                        UpdateTargetId = "list-of-people"
                    }))
{
    @Html.ValidationSummary()
    @Html.AntiForgeryToken()
    <div class="modal-body">
        @Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Name)
        @Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Age)
    </div>
    <div class="modal-footer">
        <button class="btn btn-inverse" type="submit">Save</button>
    </div>
}

Now somewhere in your application, say another partial _peoplePartial.cshtml etc:

<div>
   @foreach(var person in Model.People)
    {
        <button class="btn btn-primary edit-person" data-id="@person.PersonId">Edit</button>
    }
</div>
// this is the modal definition
<div class="modal hide fade in" id="edit-person">
    <div id="edit-person-container"></div>
</div>

    <script type="text/javascript">
    $(document).ready(function () {
        $('.edit-person').click(function () {
            var url = "/Person/EditPerson"; // the url to the controller
            var id = $(this).attr('data-id'); // the id that's given to each button in the list
            $.get(url + '/' + id, function (data) {
                $('#edit-person-container').html(data);
                $('#edit-person').modal('show');
            });
        });
     });
   </script>

When you say

(a['x']==1) and (a['y']==10)

You are implicitly asking Python to convert (a['x']==1) and (a['y']==10) to boolean values.

NumPy arrays (of length greater than 1) and Pandas objects such as Series do not have a boolean value -- in other words, they raise

ValueError: The truth value of an array is ambiguous. Use a.empty, a.any() or a.all().

when used as a boolean value. That's because its unclear when it should be True or False. Some users might assume they are True if they have non-zero length, like a Python list. Others might desire for it to be True only if all its elements are True. Others might want it to be True if any of its elements are True.

Because there are so many conflicting expectations, the designers of NumPy and Pandas refuse to guess, and instead raise a ValueError.

Instead, you must be explicit, by calling the empty(), all() or any() method to indicate which behavior you desire.

In this case, however, it looks like you do not want boolean evaluation, you want element-wise logical-and. That is what the & binary operator performs:

(a['x']==1) & (a['y']==10)

returns a boolean array.

By the way, as alexpmil notes, the parentheses are mandatory since & has a higher operator precedence than ==. Without the parentheses, a['x']==1 & a['y']==10 would be evaluated as a['x'] == (1 & a['y']) == 10 which would in turn be equivalent to the chained comparison (a['x'] == (1 & a['y'])) and ((1 & a['y']) == 10). That is an expression of the form Series and Series. The use of and with two Series would again trigger the same ValueError as above. That's why the parentheses are mandatory.

If you have a numeric column that you want to auto-increment, it might be an option to set columnDefinition directly. This has the advantage, that the schema auto-generates the value even if it is used without hibernate. This might make your code db-specific though:

import javax.persistence.Column;
@Column(columnDefinition = "serial") // postgresql

Call Wget for each link and set it to run in background.

I tried this Python code

with open('links.txt', 'r')as f1:      # Opens links.txt file with read mode
  list_1 = f1.read().splitlines()      # Get every line in links.txt
for i in list_1:                       # Iteration over each link
  !wget "$i" -bq                       # Call wget with background mode

Parameters :

      b - Run in Background
      q - Quiet mode (No Output)

Native JSON support has been included in PHP since 5.2 in the form of methods json_encode() and json_decode(). You would use the first to output a PHP variable in JSON.

I don't blame you for getting frustrated about this. The best way to look at is this. There are potentially three versions of every remote branch:

1. The actual branch on the remote repository
   (e.g., remote repo at https://example.com/repo.git, refs/heads/master)
2. Your snapshot of that branch locally (stored under refs/remotes/...)
   (e.g., local repo, refs/remotes/origin/master)
3. And a local branch that might be tracking the remote branch
   (e.g., local repo, refs/heads/master)

Let's start with git prune. This removes objects that are no longer being referenced, it does not remove references. In your case, you have a local branch. That means there's a ref named random_branch_I_want_deleted that refers to some objects that represent the history of that branch. So, by definition, git prune will not remove random_branch_I_want_deleted. Really, git prune is a way to delete data that has accumulated in Git but is not being referenced by anything. In general, it doesn't affect your view of any branches.

git remote prune origin and git fetch --prune both operate on references under refs/remotes/... (I'll refer to these as remote references). It doesn't affect local branches. The git remote version is useful if you only want to remove remote references under a particular remote. Otherwise, the two do exactly the same thing. So, in short, git remote prune and git fetch --prune operate on number 2 above. For example, if you deleted a branch using the git web GUI and don't want it to show up in your local branch list anymore (git branch -r), then this is the command you should use.

To remove a local branch, you should use git branch -d (or -D if it's not merged anywhere). FWIW, there is no git command to automatically remove the local tracking branches if a remote branch disappears.

The recommended way to style the Toolbar for a Light.DarkActionBar clone would be to use Theme.AppCompat.Light.DarkActionbar as parent/app theme and add the following attributes to the style to hide the default ActionBar:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

Then use the following as your Toolbar:

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.AppBarLayout>

For further modifications, you would create styles extending ThemeOverlay.AppCompat.Dark.ActionBar and ThemeOverlay.AppCompat.Light replacing the ones within AppBarLayout->android:theme and Toolbar->app:popupTheme. Also note that this will pick up your ?attr/colorPrimary if you have set it in your main style so you might get a different background color.

You will find a good example of this is in the current project template with an Empty Activity of Android Studio (1.4+).

For all those who don't have the option in Excel (like me), there is a macro which works and is explained here: https://www.get-digital-help.com/2015/08/03/custom-data-labels-in-x-y-scatter-chart/ Very useful

A handle is a unique identifier for an object managed by Windows. It's like a pointer, but not a pointer in the sence that it's not an address that could be dereferenced by user code to gain access to some data. Instead a handle is to be passed to a set of functions that can perform actions on the object the handle identifies.

This is possible with window.localStorage or window.sessionStorage. The difference is that sessionStorage lasts for as long as the browser stays open, localStorage survives past browser restarts. The persistence applies to the entire web site not just a single page of it.

When you need to set a variable that should be reflected in the next page(s), use:

var someVarName = "value";
localStorage.setItem("someVarKey", someVarName);

And in any page (like when the page has loaded), get it like:

var someVarName = localStorage.getItem("someVarKey");

.getItem() will return null if no value stored, or the value stored.

Note that only string values can be stored in this storage, but this can be overcome by using JSON.stringify and JSON.parse. Technically, whenever you call .setItem(), it will call .toString() on the value and store that.

MDN's DOM storage guide (linked below), has workarounds/polyfills, that end up falling back to stuff like cookies, if localStorage isn't available.

It wouldn't be a bad idea to use an existing, or create your own mini library, that abstracts the ability to save any data type (like object literals, arrays, etc.).

PHP 5.3+ solution.

$new_time = DateTime::createFromFormat('h:i A', '01:00 PM');
$time_24 = $new_time->format('H:i:s');

Output: 13:00:00

Works great when formatting date is required. Check This Answer for details.

You can use Dialog to create this easily

create a Dialog instance using the context

Dialog dialog = new Dialog(contex);

You can design your layout as you like.

You can add this layout to your dialog by dialog.setContentView(R.layout.popupview);//popup view is the layout you created

then you can access its content (textviews, etc.) by using findViewById method

TextView txt = (TextView)dialog.findViewById(R.id.textbox);

you can add any text here. the text can be stored in the String.xml file in res\values.

txt.setText(getString(R.string.message));

then finally show the pop up menu

dialog.show();

Quick fix. Create whole structure tr > td > button; then find button inside; attach event on it; end filtering of chain and at the and insert it into dom.

$("#myButton").click(function () {
    var test = $('<tr><td><button>Test</button></td></tr>').find('button').click(function () {
        alert('hi');
    }).end();

    $("#nodeAttributeHeader").attr('style', 'display: table-row;');
    $("#addNodeTable tr:last").before(test);
});

If you're already running a php page then

php bit:

    $json   =   json_encode($_REQUEST, JSON_FORCE_OBJECT);
    print "<script>var getVars = $json;</script>";

js bit:

    var param1var = getVars.param1var;

But for Html pages Jose Basilio's solution looks good to me.

Good luck!

I used a hidden checkbox to persistent view of some message. The checkbox could be hidden (display:none) or not. This is a tiny code that I could write.

You can see and test the demo on JSFiddle

HTML:

<input type=checkbox id="show">
<label for="show">Help?</label>
<span id="content">Do you need some help?</span>

CSS:

#show,#content{display:none;}
#show:checked~#content{display:block;}

Run code snippet:

#show,#content{display:none;}_x000D_
#show:checked~#content{display:block;}

<input id="show" type=checkbox>_x000D_
<label for="show">Click for Help</label>_x000D_
<span  id="content">Do you need some help?</span>

Well in fact TryGetValue is faster. How much faster? It depends on the dataset at hand. When you call the Contains method, Dictionary does an internal search to find its index. If it returns true, you need another index search to get the actual value. When you use TryGetValue, it searches only once for the index and if found, it assigns the value to your variable.

Edit:

Ok, I understand your confusion so let me elaborate:

Case 1:

if (myDict.Contains(someKey))
     someVal = myDict[someKey];

In this case there are 2 calls to FindEntry, one to check if the key exists and one to retrieve it

Case 2:

myDict.TryGetValue(somekey, out someVal)

In this case there is only one call to FindKey because the resulting index is kept for the actual retrieval in the same method.

For Python 3.x

from re import finditer
for match in finditer("pattern", "string"):
    print(match.span(), match.group())

You shall get \n separated tuples (comprising first and last indices of the match, respectively) and the match itself, for each hit in the string.

Just add ExecJS and the Ruby Racer in your gem file and run bundle install after.

gem 'execjs'

gem 'therubyracer'

Everything should be fine after.

'Millis since unix epoch' represents an instant, so you should use the Instant class:

private long toEpochMilli(LocalDateTime localDateTime)
{
  return localDateTime.atZone(ZoneId.systemDefault())
    .toInstant().toEpochMilli();
}

What you want to do is a combination of part of 1 and all of 2.

You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.

But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.

From the javadoc:

Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.

The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.

Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:

import static org.mockito.Mockito.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

class ClassWithStatics {
  public static String getString() {
    return "String";
  }

  public static int getInt() {
    return 1;
  }
}

@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
  @Test
  public void test() {
    PowerMockito.mockStatic(ClassWithStatics.class);

    when(ClassWithStatics.getString()).thenReturn("Hello!");

    System.out.println("String: " + ClassWithStatics.getString());
    System.out.println("Int: " + ClassWithStatics.getInt());
  }
}

The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.

No you can't use bind variables that way. In your second example :into_bind in v_query_str is just a placeholder for value of variable v_num_of_employees. Your select into statement will turn into something like:

SELECT COUNT(*) INTO  FROM emp_...

because the value of v_num_of_employees is null at EXECUTE IMMEDIATE.

Your first example presents the correct way to bind the return value to a variable.

Edit

The original poster has edited the second code block that I'm referring in my answer to use OUT parameter mode for v_num_of_employees instead of the default IN mode. This modification makes the both examples functionally equivalent.

You can use it

$params = request()->all();

without

import Illuminate\Http\Request OR

use Illuminate\Support\Facades\Request OR other.

1. Stop your Apache server from running.
2. Download the most recent version of XAMPP that contains a release of PHP 5.2.* from the SourceForge site linked at the apachefriends website.
3. Rename the PHP file in your current installation (MAC OSX: /xamppfiles/modules/libphp.so) to something else (just in case).
4. Copy the PHP file located in the same directory tree from the older XAMPP installation that you just downloaded, and place it in the directory of the file you just renamed.
5. Start the Apache server, and generate a fresh version of phpinfo().
6. Once you confirm that the PHP version has been lowered, delete the remaining files from the older XAMPP install.
7. Fun ensues.

I just confirmed that this works when using a version of PHP 5.2.9 from XAMPP for OS X 1.0.1 (April 2009), and surgically moving it to XAMPP for OS X 1.7.2 (August 2009).

You seem to be emphasizing the need for a positional association with your data, so wouldn't an associative array be more fitting?

Dictionary<int, string> foo = new Dictionary<int, string>();
foo[2] = "string";

Check the project properties. It's configurable there if you are using another .net windows application for example

I had also similar problem. In my case brokerUrl was not configured properly. So that's way I received following Error:

Cause: Error While attempting to add new Connection to the pool: nested exception is javax.jms.JMSException: Could not connect to broker URL : tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused

& I resolved it following way.

   ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();

  connectionFactory.setBrokerURL("tcp://hostname:61616");
  connectionFactory.setUserName("admin");
  connectionFactory.setPassword("admin");

Supplementing the answer by p.s.w.g, here are three other ways of achieving this using lodash 4.17.5, without using _.includes():

Say you want to add object entry to an array of objects numbers, only if entry does not exist already.

let numbers = [
    { to: 1, from: 2 },
    { to: 3, from: 4 },
    { to: 5, from: 6 },
    { to: 7, from: 8 },
    { to: 1, from: 2 } // intentionally added duplicate
];

let entry = { to: 1, from: 2 };

/* 
 * 1. This will return the *index of the first* element that matches:
 */
_.findIndex(numbers, (o) => { return _.isMatch(o, entry) });
// output: 0


/* 
 * 2. This will return the entry that matches. Even if the entry exists
 *    multiple time, it is only returned once.
 */
_.find(numbers, (o) => { return _.isMatch(o, entry) });
// output: {to: 1, from: 2}


/* 
 * 3. This will return an array of objects containing all the matches.
 *    If an entry exists multiple times, if is returned multiple times.
 */
_.filter(numbers, _.matches(entry));
// output: [{to: 1, from: 2}, {to: 1, from: 2}]

If you want to return a Boolean, in the first case, you can check the index that is being returned:

_.findIndex(numbers, (o) => { return _.isMatch(o, entry) }) > -1;
// output: true

I prefer Python 3.x way.

cal = 123.4567
print(f"result {cal:.4E}")

4 indicates how many digits are shown shown in the floating part.

cal = 123.4567
totalDigitInFloatingPArt = 4
print(f"result {cal:.{totalDigitInFloatingPArt}E} ")

I know this may be obvious for most people who use RegEx frequently, but in case any readers are new to RegEx, I thought I should point out an observation I made that was helpful for one of my projects.

In a previous answer from @kennytm:

^\d{5}(?:[-\s]\d{4})?$

…? = The pattern before it is optional (for condition 1)

If you want to allow both standard 5 digit and +4 zip codes, this is a great example.

To match only zip codes in the US 'Zip + 4' format as I needed to do (conditions 2 and 3 only), simply remove the last ? so it will always match the last 5 character group.

A useful tool I recommend for tinkering with RegEx is linked below:

https://regexr.com/

I use this tool frequently when I find RegEx that does something similar to what I need, but could be tailored a bit better. It also has a nifty RegEx reference menu and informative interface that keeps you aware of how your changes impact the matches for the sample text you entered.

If I got anything wrong or missed an important piece of information, please correct me.

Hope that helps!

The Answer already posted .But We can use the jquery in this way also

demo

$(function(){
    $('#check1').click(function() {
        if($('#check1').attr('checked'))
            alert('checked');
        else
            alert('unchecked');
    });

    $('#check2').click(function() {
        if(!$('#check2').attr('checked'))
            alert('unchecked');
        else
            alert('checked');
    });
});

Just to clarify better and offer another solution. Arc [A] command use the current position as a starting point so you have to use Moveto [M] command first.

Then the parameters of Arc are the following:

rx, ry, x-axis-rotation, large-arc-flag, sweep-flag, xf, yf

If we define for example the following svg file:

<svg viewBox="0 0 500 500">_x000D_
    <path fill="red" d="_x000D_
    M 250 250_x000D_
    A 100 100 0 0 0 450 250_x000D_
    Z"/> _x000D_
</svg>

You will set the starting point with M the ending point with the parameters xf and yf of A.

We are looking for circles so we set rx equal to ry doing so basically now it will try to find all the circle of radius rx that intersect the starting and end point.

import numpy as np

def write_svgarc(xcenter,ycenter,r,startangle,endangle,output='arc.svg'):
    if startangle > endangle: 
        raise ValueError("startangle must be smaller than endangle")

    if endangle - startangle < 360:
        large_arc_flag = 0
        radiansconversion = np.pi/180.
        xstartpoint = xcenter + r*np.cos(startangle*radiansconversion)
        ystartpoint = ycenter - r*np.sin(startangle*radiansconversion)
        xendpoint = xcenter + r*np.cos(endangle*radiansconversion)
        yendpoint = ycenter - r*np.sin(endangle*radiansconversion)
        #If we want to plot angles larger than 180 degrees we need this
        if endangle - startangle > 180: large_arc_flag = 1
        with open(output,'a') as f:
            f.write(r"""<path d=" """)
            f.write("M %s %s" %(xstartpoint,ystartpoint))
            f.write("A %s %s 0 %s 0 %s %s" 
                    %(r,r,large_arc_flag,xendpoint,yendpoint))
            f.write("L %s %s" %(xcenter,ycenter))
            f.write(r"""Z"/>""" )

    else:
        with open(output,'a') as f:
            f.write(r"""<circle cx="%s" cy="%s" r="%s"/>"""
                    %(xcenter,ycenter,r))

You can have a more detailed explanation in this post that I wrote.

Here you can set hidden's value at onchange event of dropdown list :

$('#myDropDown').bind('change', function () {
  $('#myHidden').val('setted value');
});

your hidden and drop down list :

<input type="hidden" id="myHidden" />

<select id="myDropDown">
   <option value="opt 1">Option 1</option>
   <option value="opt 2">Option 2</option>
   <option value="opt 3">Option 3</option>
</ select>

This should work for matches that might overlap:

public static void main(String[] args) {
    String input = "aaaaaaaa";
    String regex = "aa";
    Pattern pattern = Pattern.compile(regex);
    Matcher matcher = pattern.matcher(input);
    int from = 0;
    int count = 0;
    while(matcher.find(from)) {
        count++;
        from = matcher.start() + 1;
    }
    System.out.println(count);
}

Easier way:

#required_number = 18

required_number=input("Insert a number: ")
while required_number != 18
    print("Oops! Something is wrong")
    required_number=input("Try again: ")
if required_number == '18'
    print("That's right!")

A volatile + synchronization is a fool proof solution for an operation(statement) to be fully atomic which includes multiple instructions to the CPU.

Say for eg:volatile int i = 2; i++, which is nothing but i = i + 1; which makes i as the value 3 in the memory after the execution of this statement. This includes reading the existing value from memory for i(which is 2), load into the CPU accumulator register and do with the calculation by increment the existing value with one(2 + 1 = 3 in accumulator) and then write back that incremented value back to the memory. These operations are not atomic enough though the value is of i is volatile. i being volatile guarantees only that a SINGLE read/write from memory is atomic and not with MULTIPLE. Hence, we need to have synchronized also around i++ to keep it to be fool proof atomic statement. Remember the fact that a statement includes multiple statements.

Hope the explanation is clear enough.

In my limited experience with binary tree, I think:

1. Strictly Binary Tree:Every node except the leaf nodes have two children or only have a root node.
2. Full Binary Tree: A binary tree of H strictly(or exactly) containing 2^(H+1) -1 nodes , it's clear that which every level has the most nodes. Or in short a strict binary tree where all leaf nodes are at same level.
3. Complete Binary Tree: It is a binary tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible.

Monkey is right, according to the link given by monkey

Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location.

I am not sure if it is angular's fault that no map files were generated. But you can turn off source map files by unchecking this option in chrome console setting

There is a simple way to verify if a service is running

systemctl status service_name

Try PostgreSQL:

systemctl status postgresql

Here you are

Html

<input id="ProductId_a183060c-1030-4037-ae57-0015be92da0e" type="checkbox" value="true">

JavaScript

<script>
    $(document).ready(function () {

      $('input[id^="ProductId_"]').click(function () {

        if ($(this).prop('checked')) {
           // do what you need here     
           alert("Checked");
        }
        else {
           // do what you need here         
           alert("Unchecked");
        }
      });

  });
</script>

Dont forget to add this code in your MainActivity.java:

MainActivity.java

mShaker = new ShakeListener(this);
mShaker.setOnShakeListener(new ShakeListener.OnShakeListener () {
    public void onShake() {
        Toast.makeText(MainActivity.this, "Shake " , Toast.LENGTH_LONG).show();        
    }
});

@Override
protected void onResume() {
    super.onResume();
    mShaker.resume();
}

@Override
protected void onPause() {
    super.onPause();
    mShaker.pause();
}

Or I give you a link about this stuff.

You don't feel bad about using 'non post-back controls' anymore - and figuring how to smush them into a traditional asp.net environment.

This means that modern (free to use) javascript controls such this or this or this can all be used without that trying to fit a round peg in a square hole feel.

If you want to change the user at git Bash .You just need to configure particular user and email(globally) at the git bash.

$ git config --global user.name "abhi"
$ git config --global user.email "[email protected]"

Note: No need to delete the user from Keychain .

Embedded Emmet could do the trick:

1. Select text (optional)
2. Open command palette (usually Ctrl+Shift+P)
3. Execute Emmet: Wrap with Abbreviation
4. Enter a tag div (or an abbreviation .wrapper>p)
5. Hit Enter

Command can be assigned to a keybinding.

This thing even supports passing arguments:

{
    "key": "ctrl+shift+9",
    "command": "editor.emmet.action.wrapWithAbbreviation",
    "when": "editorHasSelection",
    "args": {
        "abbreviation": "span"
    }
},

Use it like this:

• span.myCssClass
• span#myCssId
• b
• b.myCssClass

This is one of the dumb mistakes I've done. I spent a lot of time trying to debug this problem and tried all the responses posted above, but in the end, it was one of my many dumb mistakes.

I was using org.apache.logging.log4j.Logger (:fml:) whereas I should have used org.apache.log4j.Logger. Using this correct logger saved my evening.

I think @Flo254 chained $salt to $password1and stored them to $hashed variable. $hashed variable goes inside INSERT query with $salt.

Is just casting the value returned by time()

#include <stdio.h>
#include <time.h>

int main(void) {
    printf("Timestamp: %d\n",(int)time(NULL));
    return 0;
}

what you want?

To get microseconds since the epoch, from C11 on, the portable way is to use

int timespec_get(struct timespec *ts, int base)

Unfortunately, C11 is not yet available everywhere, so as of now, the closest to portable is using one of the POSIX functions clock_gettime or gettimeofday (marked obsolete in POSIX.1-2008, which recommends clock_gettime).

The code for both functions is nearly identical:

#include <stdio.h>
#include <time.h>
#include <stdint.h>
#include <inttypes.h>

int main(void) {

    struct timespec tms;

    /* The C11 way */
    /* if (! timespec_get(&tms, TIME_UTC)) { */

    /* POSIX.1-2008 way */
    if (clock_gettime(CLOCK_REALTIME,&tms)) {
        return -1;
    }
    /* seconds, multiplied with 1 million */
    int64_t micros = tms.tv_sec * 1000000;
    /* Add full microseconds */
    micros += tms.tv_nsec/1000;
    /* round up if necessary */
    if (tms.tv_nsec % 1000 >= 500) {
        ++micros;
    }
    printf("Microseconds: %"PRId64"\n",micros);
    return 0;
}

When you do echo $array;, PHP will simply echo 'Array' since it can't convert an array to a string. So The 'A' that you are actually getting is the first letter of Array, which is correct.

You might actually need

echo json_encode($array);

This should get you what you want.

EDIT : And obviously, you'd need to change your JS to work with JSON instead of just text (as pointed out by @genesis)

Try this code. it worked for me.

 function getInvoiceID(url, invoiceId) {
    return $.ajax({
        type: 'POST',
        url: url,
        data: { invoiceId: invoiceId },
        async: false,
    });
}
function isInvoiceIdExists(url, invoiceId) {
    $.when(getInvoiceID(url, invoiceId)).done(function (data) {
        if (!data) {

        }
    });
}

Put the textarea to a form, naming them, and just use the DOM objects easily, like this:

<body onload="form1.box.value = 'Welcome!'">
  <form name="form1">
    <textarea name="box"></textarea>
  </form>
</body>

In winform datagrid, right click to view its properties. It has a property called DefaultCellStyle. Click the ellipsis on DefaultCellStyle, then it will present Cell Style Builder window which has the option to change the font size.

Its easy.

Generically, do/while is good for any sort of loop construct where one must execute the loop at least once. It is possible to emulate this sort of looping through either a straight while or even a for loop, but often the result is a little less elegant. I'll admit that specific applications of this pattern are fairly rare, but they do exist. One which springs to mind is a menu-based console application:

do {
    char c = read_input();

    process_input(c);
} while (c != 'Q');

use SimpleDateFormat to first parse() String to Date and then format() Date to String

You can use python-docx2txt library to read text from Microsoft Word documents. It is an improvement over python-docx library as it can, in addition, extract text from links, headers and footers. It can even extract images.

You can install it by running: pip install docx2txt.

Let's download and read the first Microsoft document on here:

import docx2txt
my_text = docx2txt.process("test.docx")
print(my_text)

Here is a screenshot of the Terminal output the above code:

EDIT:

This does NOT work for .doc files. The only reason I am keep this answer is that it seems there are people who find it useful for .docx files.

It is possible with EXISTS condition. WHERE EXISTS tests for the existence of any records in a subquery. EXISTS returns true if the subquery returns one or more records. Here is an example

UPDATE  TABLE_NAME 
SET val1=arg1 , val2=arg2
WHERE NOT EXISTS
    (SELECT FROM TABLE_NAME WHERE val1=arg1 AND val2=arg2)

I was playing around with this solution to maintain consistency throughout the app:

def bootstrap_django_fields(field_klass, css_class):
    class Wrapper(field_klass):
        def __init__(self, **kwargs):
            super().__init__(**kwargs)

        def widget_attrs(self, widget):
            attrs = super().widget_attrs(widget)
            if not widget.is_hidden:
                attrs["class"] = css_class
            return attrs

    return Wrapper


MyAppCharField = bootstrap_django_fields(forms.CharField, "form-control")

Then you don't have to define your css classes on a form by form basis, just use your custom form field.

It's also technically possible to redefine Django's forms classes on startup like so:

forms.CharField = bootstrap_django_fields(forms.CharField, "form-control")

Then you could set the styling globally even for apps not in your direct control. This seems pretty sketchy, so I am not sure if I can recommend this.

Converting from dict to list is made easy in Python. Three examples:

>> d = {'a': 'Arthur', 'b': 'Belling'}

>> d.items()
[('a', 'Arthur'), ('b', 'Belling')]

>> d.keys()
['a', 'b']

>> d.values()
['Arthur', 'Belling']

Haven't tried it myself, but this page has a list of plugin modules that run in Linux' built in iptables IP filtering system. One of the modules is called "nth", and allows you to set up a rule that will drop a configurable rate of the packets. Might be a good place to start, at least.

Let's start with this small df:

import pandas as pd
import time as tm
import numpy as np
n=10
a=np.arange(0,n**2)
df=pd.DataFrame(a.reshape(n,n))

We'll so have

df
Out[25]: 
        0   1   2   3   4   5   6   7   8   9
    0   0   1   2   3   4   5   6   7   8   9
    1  10  11  12  13  14  15  16  17  18  19
    2  20  21  22  23  24  25  26  27  28  29
    3  30  31  32  33  34  35  36  37  38  39
    4  40  41  42  43  44  45  46  47  48  49
    5  50  51  52  53  54  55  56  57  58  59
    6  60  61  62  63  64  65  66  67  68  69
    7  70  71  72  73  74  75  76  77  78  79

    9  90  91  92  93  94  95  96  97  98  99

With this we have:

df.iloc[3,3]
Out[33]: 33

df.iat[3,3]
Out[34]: 33

df.iloc[:3,:3]
Out[35]: 
    0   1   2   3
0   0   1   2   3
1  10  11  12  13
2  20  21  22  23
3  30  31  32  33



df.iat[:3,:3]
Traceback (most recent call last):
   ... omissis ...
ValueError: At based indexing on an integer index can only have integer indexers

Thus we cannot use .iat for subset, where we must use .iloc only.

But let's try both to select from a larger df and let's check the speed ...

So with .loc we can manage subsets and with .at only a single scalar, but .at is faster than .loc

If you want to copy a class instance, you can use Object.assign too, but you need to pass a new instance as a first parameter (instead of {}) :

class MyClass {
    public prop1: number;
    public prop2: number;

    public summonUnicorn(): void {
        alert('Unicorn !');
    }
}

let instance = new MyClass();
instance.prop1 = 12;
instance.prop2 = 42;

let wrongCopy = Object.assign({}, instance);
console.log(wrongCopy.prop1); // 12
console.log(wrongCopy.prop2); // 42
wrongCopy.summonUnicorn() // ERROR : undefined is not a function

let goodCopy = Object.assign(new MyClass(), instance);
console.log(goodCopy.prop1); // 12
console.log(goodCopy.prop2); // 42
goodCopy.summonUnicorn() // It works !

This should get you started. I haven't played with it lately but I downloaded a very old version a while back and it seemed pretty solid. This one is updated to Visual Studio 2008 as well so check out the docs!

The pop version wasn't quite right. I think you want:

>>> print('foofoobar'.split('foo', 1).pop())
foobar

Add a control, where you want to set focus then change its property like below

<asp:TextBox ID="txtDummy" runat="server" Text="" Width="2" ReadOnly="true" BorderStyle="None" BackColor="Transparent"></asp:TextBox>

In the codebehind, just call like below txtDummy.Focus()

this method is working in all browser.

I know others have answered this already. But a very important factor here that may help other people experiencing similar issue:

You must have an onChange handler added in your input field (e.g. textField, checkbox, radio, etc). Always handle activity through the onChange handler.

Example:

<input ... onChange={ this.myChangeHandler} ... />

When you are working with checkbox you may need to handle its checked state with !!.

Example:

<input type="checkbox" checked={!!this.state.someValue} onChange={.....} >

You can just locate pg_dump and use the full path in command

locate pg_dump

/usr/bin/pg_dump
/usr/bin/pg_dumpall
/usr/lib/postgresql/9.3/bin/pg_dump
/usr/lib/postgresql/9.3/bin/pg_dumpall
/usr/lib/postgresql/9.6/bin/pg_dump
/usr/lib/postgresql/9.6/bin/pg_dumpall

Now just use the path of the desired version in the command

/usr/lib/postgresql/9.6/bin/pg_dump books > books.out

ok, Im using mac to generate my self signed keys. Here is the working method I used.

I created a shell script to speed up my key generation.

genkey.sh

#/bin/sh

ssh-keygen -f host.key
openssl req -new -key host.key -out request.csr
openssl x509 -req -days 99999 -in request.csr -signkey host.key -out server.crt
openssl pkcs12 -export -inkey host.key -in server.crt -out private_public.p12 -name "SslCert"
openssl base64 -in private_public.p12 -out Base64.key

add the +x execute flag to the script

chmod +x genkey.sh

then call genkey.sh

./genkey.sh

I enter a password (important to include a password at least for the export at the end)

Enter pass phrase for host.key:
Enter Export Password:   {Important to enter a password here}
Verifying - Enter Export Password: { Same password here }

I then take everything in Base64.Key and put it into a string named sslKey

private string sslKey = "MIIJiAIBA...................................." +
                        "......................ETC...................." +
                        "......................ETC...................." +
                        "......................ETC...................." +
                        ".............ugICCAA=";

I then used a lazy load Property getter to get my X509 Cert with a private key.

X509Certificate2 _serverCertificate = null;
X509Certificate2 serverCertificate{
    get
    {
        if (_serverCertificate == null){
            string pass = "Your Export Password Here";
            _serverCertificate = new X509Certificate(Convert.FromBase64String(sslKey), pass, X509KeyStorageFlags.Exportable);
        }
        return _serverCertificate;
    }
}

I wanted to go this route because I am using .net 2.0 and Mono on mac and I wanted to use vanilla Framework code with no compiled libraries or dependencies.

My final use for this was the SslStream to secure TCP communication to my app

SslStream sslStream = new SslStream(serverCertificate, false, SslProtocols.Tls, true);

I hope this helps other people.

NOTE

Without a password I was unable to correctly unlock the private key for export.

A simple example, where a change on a dropdown list triggers an ajax form-submit to reload a datagrid:

<div id="pnlSearch">

    <% using (Ajax.BeginForm("UserSearch", "Home", new AjaxOptions { UpdateTargetId = "pnlSearchResults" }, new { id="UserSearchForm" }))
    { %>

        UserType: <%: Html.DropDownList("FilterUserType", Model.UserTypes, "--", new { onchange = "$('#UserSearchForm').trigger('submit');" })%>

    <% } %>

</div>

The trigger('onsubmit') is the key thing: it calls the onsubmit function that MVC has grafted onto the form.

NB. The UserSearchResults controller returns a PartialView that renders a table using the supplied Model

<div id="pnlSearchResults">
    <% Html.RenderPartial("UserSearchResults", Model); %>
</div>

I ran into this when checking on a null or empty string

if (x == NULL || x == '') {

changed it to

if (is.null(x) || x == '') {

Note: Obviously, this is a simple example explaining just how to set up a CtrlC handler, but as always there are rules that need to be obeyed in order not to break something else. Please read the comments below.

The sample code from above:

#include  <stdio.h>
#include  <signal.h>
#include  <stdlib.h>

void     INThandler(int);

int  main(void)
{
     signal(SIGINT, INThandler);
     while (1)
          pause();
     return 0;
}

void  INThandler(int sig)
{
     char  c;

     signal(sig, SIG_IGN);
     printf("OUCH, did you hit Ctrl-C?\n"
            "Do you really want to quit? [y/n] ");
     c = getchar();
     if (c == 'y' || c == 'Y')
          exit(0);
     else
          signal(SIGINT, INThandler);
     getchar(); // Get new line character
}

  INSERT INTO Table2 (val) VALUES (tableId);
END $$;

Tested with psql (10.3, server 9.6.8)

Simple 3 steps:

1- Right click on database ? Tasks ? restore ? Database

2- Check Device as source and locate .bak (or zipped .bak) file

3- In the left pane click on options and:

• check Overwrite the existing database.
• uncheck Take tail-log backup before restore
• check Close existing connection to destination database.

Other options are really optional (and important of course)!

Here is a working solution:

#include <stdio.h>
#include <string.h>

int main(int argc, char** argv) 
{
      char str1[16];
      char str2[16];
      strcpy(str1, "sssss");
      strcpy(str2, "kkkk");
      strcat(str1, str2);
      printf("%s", str1);
      return 0;
}

Output:

ssssskkkk

You have to allocate memory for your strings. In the above code, I declare str1 and str2 as character arrays containing 16 characters. I used strcpy to copy characters of string literals into them, and strcat to append the characters of str2 to the end of str1. Here is how these character arrays look like during the execution of the program:

After declaration (both are empty): 
str1: [][][][][][][][][][][][][][][][][][][][] 
str2: [][][][][][][][][][][][][][][][][][][][]

After calling strcpy (\0 is the string terminator zero byte): 
str1: [s][s][s][s][s][\0][][][][][][][][][][][][][][] 
str2: [k][k][k][k][\0][][][][][][][][][][][][][][][]

After calling strcat: 
str1: [s][s][s][s][s][k][k][k][k][\0][][][][][][][][][][] 
str2: [k][k][k][k][\0][][][][][][][][][][][][][][][]

So another way, which I prefer, is to just split the values, for example:

#/path/to/config.cfg
[Numbers]
first_row = 1,2,4,8,12,24,36,48

Could be loaded like this into a list of strings or integers, as follows:

import configparser

config = configparser.ConfigParser()
config.read('/path/to/config.cfg')

# Load into a list of strings
first_row_strings = config.get('Numbers', 'first_row').split(',')

# Load into a list of integers
first_row_integers = [int(x) for x in config.get('Numbers', 'first_row').split(',')]

This method prevents you from needing to wrap your values in brackets to load as JSON.

public class NaturalSort: IComparer<string>
{
          [DllImport("shlwapi.dll", CharSet = CharSet.Unicode)]
          public static extern int StrCmpLogicalW(string x, string y);

          public int Compare(string x, string y)
          {
                 return StrCmpLogicalW(x, y);
          }
}

arr = arr.OrderBy(x => x, new NaturalSort()).ToArray();

The reason I needed it was to get filed in a directory whose filenames started with a number:

public static FileInfo[] GetFiles(string path)
{
  return new DirectoryInfo(path).GetFiles()
                                .OrderBy(x => x.Name, new NaturalSort())
                                .ToArray();
}

You could do it using SUBSTRING() function:

UPDATE table SET column = SUBSTRING(column, 0, LEN(column) + 1 - N)

Removes the last N characters from every row in the column

Create a Keybinding

To auto indent on Sublime text 3 with a key bind try going to

Preferences > Key Bindings - users

And adding this code between the square brackets

{"keys": ["alt+shift+f"], "command": "reindent", "args": {"single_line": false}}

it sets shift + alt + f to be your full page auto indent.

Source here

Note: if this doesn't work correctly then you should convert your indentation to tabs. Also comments in your code can push your code to the wrong indentation level and may have to be moved manually.

Not tested but you can try something like this :

Declare @count as int
Set @count=1
Declare @inputFile varchar(max)
Declare @Sample Table
(id int,filepath varchar(max) ,Isexists char(3))

while @count<(select max(id) from yourTable)
BEGIN
Set @inputFile =(Select filepath from yourTable where id=@count)
DECLARE @isExists INT
exec master.dbo.xp_fileexist @inputFile , 
@isExists OUTPUT
insert into @Sample
Select @count,@inputFile ,case @isExists 
when 1 then 'Yes' 
else 'No' 
end as isExists
set @count=@count+1
END

I also faced the following Error in my system (Mac)

Error: Could not find or load main class org.codehaus.plexus.classworlds.launcher.Launcher

After doing some random browsing, I came across the link "http://maven.apache.org/install.html" that says "JAVA_HOME" should be set to "/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre".

When I changed "JAVA_HOME" as stated above in ".bash_profile", "mvn" command started working but "javac -version" command stopped working.

When I typed "javac -version" command, I got the following error

Unable to locate an executable at "/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre/bin/javac" (-1)

Hence I rolled back my "JAVA_HOME" to "/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home" in ".bash_profile" and added the following line at the top in "mvn" script

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre

Now both "mvn" and "javac" commands worked properly, but after careful observation of the mvn script, I could not make the difference between the following commands

/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/java -classpath /Users/venkatarajeevmandava/Documents/Maven/apache-maven-3.6.1/boot/plexus-classworlds-2.6.0.jar -Dclassworlds.conf=/Users/venkatarajeevmandava/Documents/Maven/apache-maven-3.6.1/bin/m2.conf -Dmaven.home=/Users/venkatarajeevmandava/Documents/Maven/apache-maven-3.6.1 -Dlibrary.jansi.path=/Users/venkatarajeevmandava/Documents/Maven/apache-maven-3.6.1/lib/jansi-native -Dmaven.multiModuleProjectDirectory=/Users/venkatarajeevmandava/Documents/Maven/apache-maven-3.6.1/bin org.codehaus.plexus.classworlds.launcher.Launcher

In the above the first command caused the following error

Error: Could not find or load main class org.codehaus.plexus.classworlds.launcher.Launcher

while the second command worked fine. Please Note that both the above paths have "java" command while one is from "jre" the other is from "jdk"

Other global variables are as following in ".bash_profile"

export M2_HOME=/Users/venkatarajeevmandava/Documents/Maven/apache-maven-3.6.1

export PATH=$PATH:$M2_HOME/bin

Couldn't that just be done by only using a positive button?

You can run as you run your shell script. This example to run from command line environment example

./bin/spark-shell :- this is the path of your spark-shell under bin /home/fold1/spark_program.py :- This is the path where your python program is there.

So:

./bin.spark-shell /home/fold1/spark_prohram.py

I put the User import into the settings file for managing the rest call token like this

# settings.py
from django.contrib.auth.models import User
def jwt_get_username_from_payload_handler(payload):
   ....

JWT_AUTH = {
    'JWT_PAYLOAD_GET_USERNAME_HANDLER': jwt_get_username_from_payload_handler,
    'JWT_PUBLIC_KEY': PUBLIC_KEY,
    'JWT_ALGORITHM': 'RS256',
    'JWT_AUDIENCE': API_IDENTIFIER,
    'JWT_ISSUER': JWT_ISSUER,
    'JWT_AUTH_HEADER_PREFIX': 'Bearer',
}
REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.IsAuthenticated',
    ),
    'DEFAULT_AUTHENTICATION_CLASSES': (
       'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
    ),
}

Because at that moment, Django libs are not ready yet. Therefore, I put the import inside the function and it started to work. The function needs to be called after the server is started

As everybody else has said, there is no difference. (As a sanity check I did some tests, but it was a waste of time, of course they work the same.)

But there are actually FOUR types of inequality operators: !=, ^=, <>, and ¬=. See this page in the Oracle SQL reference. On the website the fourth operator shows up as ÿ= but in the PDF it shows as ¬=. According to the documentation some of them are unavailable on some platforms. Which really means that ¬= almost never works.

Just out of curiosity, I'd really like to know what environment ¬= works on.

you can creat symlink to your libusb after locate it in your system :

sudo ln -s /lib/x86_64-linux-gnu/libusb-1.0.so.0 /usr/lib/libusbx-1.0.so.0.1.0 

sudo ln -s /lib/x86_64-linux-gnu/libusb-1.0.so.0 /usr/lib/libusbx-1.0.so

In vba the function is MOD. e.g

 5 MOD 2

Here is a useful link.

public static void main(String[] args) throws InterruptedException {
  //type code


  short z=1000;
  Thread.sleep(z);/*will provide 1 second delay. alter data type of z or value of z for longer delays required */

  //type code
}

eg:-

class TypeCasting {

  public static void main(String[] args) throws InterruptedException {
    short f = 1;
    int a = 123687889;
    short b = 2;
    long c = 4567;
    long d=45;
    short z=1000;
    System.out.println("Value of a,b and c are\n" + a + "\n" + b + "\n" + c + "respectively");
    c = a;
    b = (short) c;
    System.out.println("Typecasting...........");
    Thread.sleep(z);
    System.out.println("Value of B after Typecasting" + b);
    System.out.println("Value of A is" + a);


  }
}

In the syntax s/foo/bar, \r and \n have different meanings, depending on context.

Short:

For foo:

\r == "carriage return" (CR / ^M)
\n == matches "line feed" (LF) on Linux/Mac, and CRLF on Windows

For bar:

\r == produces LF on Linux/Mac, CRLF on Windows
\n == "null byte" (NUL / ^@)

When editing files in linux (i.e. on a webserver) that were initially created in a windows environment and uploaded (i.e. FTP/SFTP) - all the ^M's you see in vim, are the CR's which linux does not translate as it uses only LF's to depict a line break.

Longer (with ASCII numbers):

NUL == 0x00 == 0 == Ctrl + @ == ^@ shown in vim
LF == 0x0A == 10 == Ctrl + J
CR == 0x0D == 13 == Ctrl + M == ^M shown in vim

Here is a list of the ASCII control characters. Insert them in Vim via Ctrl + V,Ctrl + ---key---.

In Bash or the other Unix/Linux shells, just type Ctrl + ---key---.

Try Ctrl + M in Bash. It's the same as hitting Enter, as the shell realizes what is meant, even though Linux systems use line feeds for line delimiting.

To insert literal's in bash, prepending them with Ctrl + V will also work.

Try in Bash:

echo ^[[33;1mcolored.^[[0mnot colored.

This uses ANSI escape sequences. Insert the two ^['s via Ctrl + V, Esc.

You might also try Ctrl + V,Ctrl + M, Enter, which will give you this:

bash: $'\r': command not found

Remember the \r from above? :>

This ASCII control characters list is different from a complete ASCII symbol table, in that the control characters, which are inserted into a console/pseudoterminal/Vim via the Ctrl key (haha), can be found there.

Whereas in C and most other languages, you usually use the octal codes to represent these 'characters'.

If you really want to know where all this comes from: The TTY demystified. This is the best link you will come across about this topic, but beware: There be dragons.

TL;DR

Usually foo = \n, and bar = \r.

textarea {
    overflow-y: scroll; /* Vertical scrollbar */
    overflow: scroll; /* Horizontal and vertical scrollbar*/
}

 foreach($arr as $key=>$value){
    echo($key);    // key
 }

The --net=host option is used to make the programs inside the Docker container look like they are running on the host itself, from the perspective of the network. It allows the container greater network access than it can normally get.

Normally you have to forward ports from the host machine into a container, but when the containers share the host's network, any network activity happens directly on the host machine - just as it would if the program was running locally on the host instead of inside a container.

While this does mean you no longer have to expose ports and map them to container ports, it means you have to edit your Dockerfiles to adjust the ports each container listens on, to avoid conflicts as you can't have two containers operating on the same host port. However, the real reason for this option is for running apps that need network access that is difficult to forward through to a container at the port level.

For example, if you want to run a DHCP server then you need to be able to listen to broadcast traffic on the network, and extract the MAC address from the packet. This information is lost during the port forwarding process, so the only way to run a DHCP server inside Docker is to run the container as --net=host.

Generally speaking, --net=host is only needed when you are running programs with very specific, unusual network needs.

Lastly, from a security perspective, Docker containers can listen on many ports, even though they only advertise (expose) a single port. Normally this is fine as you only forward the single expected port, however if you use --net=host then you'll get all the container's ports listening on the host, even those that aren't listed in the Dockerfile. This means you will need to check the container closely (especially if it's not yours, e.g. an official one provided by a software project) to make sure you don't inadvertently expose extra services on the machine.

for nuxt link and bootstrap v5 navbar-nav, I used a child component

             <nuxt-link
              @click.prevent.native="isDropdwonMenuVisible = !isDropdwonMenuVisible"
              to=""
              :title="item.title"
              :class="[item.cssClasses, {show: isDropdwonMenuVisible}]"
              :id="`navbarDropdownMenuLink-${index}`"
              :aria-expanded="[isDropdwonMenuVisible ? true : false]"
              class="nav-link dropdown-toggle"
              aria-current="page"
              role="button"
              data-toggle="dropdown"
            >
              {{ item.label }}
            </nuxt-link>

data() {
    return {
      isDropdwonMenuVisible: false
    }
  },

Looks like this depends heavily on your version of Excel. I am using the 2007 version and it offers no wizard option when you right click on the table. You need to click on the pivot table to make extra 'PivotTable Tools' appear to the right of the other tabs at the top of the screen. Click the 'options' tab that appears here then there is a big icon on the middle of the ribbon named 'change data source'.

A simple for loop which tests the checked property and appends the checked ones to a separate array. From there, you can process the array of checkboxesChecked further if needed.

// Pass the checkbox name to the function
function getCheckedBoxes(chkboxName) {
  var checkboxes = document.getElementsByName(chkboxName);
  var checkboxesChecked = [];
  // loop over them all
  for (var i=0; i<checkboxes.length; i++) {
     // And stick the checked ones onto an array...
     if (checkboxes[i].checked) {
        checkboxesChecked.push(checkboxes[i]);
     }
  }
  // Return the array if it is non-empty, or null
  return checkboxesChecked.length > 0 ? checkboxesChecked : null;
}

// Call as
var checkedBoxes = getCheckedBoxes("mycheckboxes");

To stop a running program, use Ctrl+C to terminate the process.

To handle it programmatically in python, import the sys module and use sys.exit() where you want to terminate the program.

import sys
sys.exit()

The solution is the /Y switch:

xcopy "C:\Users\ADMIN\Desktop\*.*" "D:\Backup\" /K /D /H /Y

It will be better to use xpath

from selenium import webdriver
driver.get('www.example.com')
button = driver.find_element_by_xpath('xpath')
button.click()

My solution is a combination of @Dzintars and @Quassnoi Answer.

SELECT CONCAT("ALTER TABLE ", TABLE_SCHEMA, '.', TABLE_NAME," CONVERT TO CHARACTER SET utf8mb4 ;") AS    ExecuteTheString
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA="<your-database>"
AND TABLE_TYPE="BASE TABLE";

By using CONVERT TO, this generates a scripts, which converts all the Tables of <your-database> to your requested encoding. This also changes the encoding of every column!

Why don't we just apply the definition studied at College? The result maybe inefficient but clear, as the multiplication is just a recursive subtraction and subtraction is an addition, then the addition can be performed by a recursive xor/and logic port combination.

#include <stdio.h>

int add(int a, int b){
   int rc;
   int carry;
   rc = a ^ b; 
   carry = (a & b) << 1;
   if (rc & carry) 
      return add(rc, carry);
   else
      return rc ^ carry; 
}

int sub(int a, int b){
   return add(a, add(~b, 1)); 
}

int div( int D, int Q )
{
/* lets do only positive and then
 * add the sign at the end
 * inversion needs to be performed only for +Q/-D or -Q/+D
 */
   int result=0;
   int sign=0;
   if( D < 0 ) {
      D=sub(0,D);
      if( Q<0 )
         Q=sub(0,Q);
      else
         sign=1;
   } else {
      if( Q<0 ) {
         Q=sub(0,Q);
         sign=1;
      } 
   }
   while(D>=Q) {
      D = sub( D, Q );
      result++;
   }
/*
* Apply sign
*/
   if( sign )
      result = sub(0,result);
   return result;
}

int main( int argc, char ** argv ) 
{
    printf( "2 plus 3=%d\n", add(2,3) );
    printf( "22 div 3=%d\n", div(22,3) );
    printf( "-22 div 3=%d\n", div(-22,3) );
    printf( "-22 div -3=%d\n", div(-22,-3) );
    printf( "22 div 03=%d\n", div(22,-3) );
    return 0;
}

As someone says... first make this work. Note that algorithm should work for negative Q...

This sample code should work:

var http = require('http');
var options = {method: 'HEAD', host: 'stackoverflow.com', port: 80, path: '/'};
var req = http.request(options, function(res) {
    console.log(JSON.stringify(res.headers));
  }
);
req.end();

There is also a Windows built-in program called findstr.exe with which you can search within files.

>findstr /s "provider=sqloledb" *.cs

This works for me:

.network-connections-icon {
  background-image: url(url);
  background-size: 100%;
  width: 56px;
  height: 56px;
  margin: 0 auto;
}

You need to put like this.

$('[id$=dropDownId] option:selected').val();

Array.from(new Array(row), () => new Array(col).fill(0));

You probably did not init postgres.

If you installed using HomeBrew, the init must be run before anything else becomes usable.

To see the instructions, run brew info postgres

# Create/Upgrade a Database
If this is your first install, create a database with:
     initdb /usr/local/var/postgres -E utf8

To have launchd start postgresql at login:
   ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents 
Then to load postgresql now:     
   launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist 
Or, if you don't want/need launchctl, you can just run:
    pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start

Once you have run that, it should say something like:

Success. You can now start the database server using:

postgres -D /usr/local/var/postgres or
pg_ctl -D /usr/local/var/postgres -l logfile start

If you are still having issues, check your firewall. If you use a good one like HandsOff! and it was configured to block traffic, then your page will not see the database.

With Groovy, you don't need the includes, and can just do:

String oldDate = '04-DEC-2012'
Date date = Date.parse( 'dd-MMM-yyyy', oldDate )
String newDate = date.format( 'M-d-yyyy' )

println newDate

To print:

12-4-2012

I also come across same problem, I changed transaction timeout to 15 minutes and it works. I hope this helps.

TransactionOptions options = new TransactionOptions();
options.IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted;
options.Timeout = new TimeSpan(0, 15, 0);
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required,options))
{
    sp1();
    sp2();
    ...

}

Try

sudo -su db2inst1 /opt/ibm/db2/V9.7/bin/db2 force application \(1995\)

Updated the list for further documentation.

socket.emit('message', "this is a test"); //sending to sender-client only
socket.broadcast.emit('message', "this is a test"); //sending to all clients except sender
socket.broadcast.to('game').emit('message', 'nice game'); //sending to all clients in 'game' room(channel) except sender
socket.to('game').emit('message', 'enjoy the game'); //sending to sender client, only if they are in 'game' room(channel)
socket.broadcast.to(socketid).emit('message', 'for your eyes only'); //sending to individual socketid
io.emit('message', "this is a test"); //sending to all clients, include sender
io.in('game').emit('message', 'cool game'); //sending to all clients in 'game' room(channel), include sender
io.of('myNamespace').emit('message', 'gg'); //sending to all clients in namespace 'myNamespace', include sender
socket.emit(); //send to all connected clients
socket.broadcast.emit(); //send to all connected clients except the one that sent the message
socket.on(); //event listener, can be called on client to execute on server
io.sockets.socket(); //for emiting to specific clients
io.sockets.emit(); //send to all connected clients (same as socket.emit)
io.sockets.on() ; //initial connection from a client.

Hope this helps.
