My Solution in laravel 5.2

{{ Form::open(['route' => ['votes.submit', $video->id],  'method' => 'POST']) }}
    <button type="submit" class="btn btn-primary">
        <span class="glyphicon glyphicon-thumbs-up"></span> Votar
    </button>
{{ Form::close() }}

My Routes File (under middleware)

Route::post('votar/{id}', [
    'as' => 'votes.submit',
    'uses' => 'VotesController@submit'
]);

Route::delete('votar/{id}', [
    'as' => 'votes.destroy',
    'uses' => 'VotesController@destroy'
]);

I tried following code, which works for me.

private boolean executeCommand(){
        System.out.println("executeCommand");
        Runtime runtime = Runtime.getRuntime();
        try
        {
            Process  mIpAddrProcess = runtime.exec("/system/bin/ping -c 1 8.8.8.8");
            int mExitValue = mIpAddrProcess.waitFor();
            System.out.println(" mExitValue "+mExitValue);
            if(mExitValue==0){
                return true;
            }else{
                return false;
            }
        }
        catch (InterruptedException ignore)
        {
            ignore.printStackTrace();
            System.out.println(" Exception:"+ignore);
        } 
        catch (IOException e) 
        {
            e.printStackTrace();
            System.out.println(" Exception:"+e);
        }
        return false;
    }

i used chardet to detect possible encoding of this data ( if its text ), but get {'confidence': 0.0, 'encoding': None}. Then i tried to use pickle.load and get nothing again. I tried to save this as file , test many different formats and failed here too. Maybe you tell us what type have this 16512 bytes of mysterious data?

You need to convert your private key to PKCS8 format using following command:

openssl pkcs8 -topk8 -inform PEM -outform DER -in private_key_file  -nocrypt > pkcs8_key

After this your java program can read it.

Here's another option:

with tbl_demo AS
    (SELECT TO_DATE('11/26/2013 13:18:50', 'MM/DD/YYYY HH24:MI:SS') dt1
   , TO_DATE('11/28/2013 21:59:12', 'MM/DD/YYYY HH24:MI:SS') dt2 
     FROM dual)
SELECT dt1
     , dt2
     , round(dt2 - dt1,2) diff_days
     , round(dt2 - dt1,2)*24 diff_hrs
     , numtodsinterval((dt2 - dt1),'day') diff_dd_hh_mm_ss
  from tbl_demo;

This maybe way off the track, but there are two things that spring to mind. Both of the following assume that you are running a 32bit version of Linux.

There is a process size limit on linux, seem to remember on CentOS was around 2.5gb and is configured in the kernel (i.e. a recomple to change). Your process might be hitting that once you add up all the JVM code + Permgen space and all the rest of the JVM libraries.

The second thing is something I've come across that you may be running out of address space, sounds wierd I know. Had a problem running Glassfish with a 1.5Gb heap, when it tried to complie a JSP my forking javac it would fail because the OS couldn't allocate enough address space for the newly created process even though there was 12gb of memory in the box. There may be something similar going on here.

I'm afraid the only solutions to the above two where to upgrade to a 64bit kernel.

Hope this is of some use.

I Use This Code To Get Top Second Salary

I am Also Get Error Like

The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP or FOR XML is also specified.

TOP 100 I Used To Avoid The Error

select * from ( select tbl.Coloumn1 ,CONVERT(varchar, ROW_NUMBER() OVER (ORDER BY (SELECT 1))) AS Rowno from ( select top 100 * from Table1 order by Coloumn1 desc) as tbl) as tbl where tbl.Rowno=2

In addition to the most upvoted answer here, one can also chain axhline after calling plot on a pandas's DataFrame.

SDK represents to software development kit, and IDE represents to integrated development environment. The IDE is the software or the program is used to write, compile, run, and debug such as Xcode. The SDK is the underlying engine of the IDE, includes all the platform's libraries an app needs to access. It's more basic than an IDE because it doesn't usually have graphical tools.

But this is obviously performing a 'string' comparison

No. The string will be automatically cast into a DATETIME value.

See 11.2. Type Conversion in Expression Evaluation.

When an operator is used with operands of different types, type conversion occurs to make the operands compatible. Some conversions occur implicitly. For example, MySQL automatically converts numbers to strings as necessary, and vice versa.

I use environment for that. It works automatically and you don't have to create new injectable service and most usefull for me, don't need to import via constructor.

1) Create environment variable in your environment.ts

export const environment = {
    ...
    // runtime variables
    isContentLoading: false,
    isDeployNeeded: false
}

2) Import environment.ts in *.ts file and create public variable (i.e. "env") to be able to use in html template

import { environment } from 'environments/environment';

@Component(...)
export class TestComponent {
    ...
    env = environment;
}

3) Use it in template...

<app-spinner *ngIf='env.isContentLoading'></app-spinner>

in *.ts ...

env.isContentLoading = false 

(or just environment.isContentLoading in case you don't need it for template)

You can create your own set of globals within environment.ts like so:

export const globals = {
    isContentLoading: false,
    isDeployNeeded: false
}

and import directly these variables (y)

In .NET Framework 4 and MVC this is the only representation that worked:

Replace(@"""","")

Using a backslash in whatever combination did not work...

I had a similar problem but it had to do with the structure and class of the object. I would check how dih_y2$MemberID is formatted.

Generally this problem occurs when you are modifying the keys very oftenly. Based on the server it might take some time to update the new key that you have generated and pasted in the server. So after generating the key and pasting in the server, wait for 3 to 4 hours and then try. The problem should be solved. It happened with me.

I think, that you have to declare the associated sheet!

Try something like this

objsheet(1).Cells[i,j].Value;

After reading so many articles, Stack Overflow posts and making demo applications to check variable property attributes, I decided to put all the attributes information together:

1. atomic // Default
2. nonatomic
3. strong = retain // Default
4. weak = unsafe_unretained
5. retain
6. assign // Default
7. unsafe_unretained
8. copy
9. readonly
10. readwrite // Default

In the article Variable property attributes or modifiers in iOS you can find all the above-mentioned attributes, and that will definitely help you.

1. atomic

   • atomic means only one thread access the variable (static type).
   • atomic is thread safe.
   • But it is slow in performance
   • atomic is the default behavior
   • Atomic accessors in a non garbage collected environment (i.e. when using retain/release/autorelease) will use a lock to ensure that another thread doesn't interfere with the correct setting/getting of the value.
   • It is not actually a keyword.
     
     

   Example:

       @property (retain) NSString *name;
   
       @synthesize name;
   

2. nonatomic

   • nonatomic means multiple thread access the variable (dynamic type).
   • nonatomic is thread-unsafe.
   • But it is fast in performance
   • nonatomic is NOT default behavior. We need to add the nonatomic keyword in the property attribute.
   • It may result in unexpected behavior, when two different process (threads) access the same variable at the same time.
     
     

   Example:

       @property (nonatomic, retain) NSString *name;
   
       @synthesize name;
   

Explanation: on what's going on here?

If we keep in mind that .replace() is equal with .remove().add() that we know by the documentation:

Replace an existing fragment that was added to a container. This is essentially the same as calling remove(Fragment) for all currently added fragments that were added with the same containerViewId and then add(int, Fragment, String) with the same arguments given here.

then what's happening is like this (I'm adding numbers to the frag to make it more clear):

// transaction.replace(R.id.detailFragment, frag1);
Transaction.remove(null).add(frag1)  // frag1 on view

// transaction.replace(R.id.detailFragment, frag2).addToBackStack(null);
Transaction.remove(frag1).add(frag2).addToBackStack(null)  // frag2 on view

// transaction.replace(R.id.detailFragment, frag3);
Transaction.remove(frag2).add(frag3)  // frag3 on view

^{(here all misleading stuff starts to happen)}

Remember that .addToBackStack() is saving only transaction not the fragment as itself! So now we have frag3 on the layout:

< press back button >
// System pops the back stack and find the following saved back entry to be reversed:
// [Transaction.remove(frag1).add(frag2)]
// so the system makes that transaction backward!!!
// tries to remove frag2 (is not there, so it ignores) and re-add(frag1)
// make notice that system doesn't realise that there's a frag3 and does nothing with it
// so it still there attached to view
Transaction.remove(null).add(frag1) //frag1, frag3 on view (OVERLAPPING)

// transaction.replace(R.id.detailFragment, frag2).addToBackStack(null);
Transaction.remove(frag3).add(frag2).addToBackStack(null)  //frag2 on view

< press back button >
// system makes saved transaction backward
Transaction.remove(frag2).add(frag3) //frag3 on view

< press back button >
// no more entries in BackStack
< app exits >

Possible solution

Consider implementing FragmentManager.BackStackChangedListener to watch for changes in the back stack and apply your logic in onBackStackChanged() methode:

• Trace a count of transaction;
• Check particular transaction by name FragmentTransaction.addToBackStack(String name);
• Etc.

An IP camera can be accessed in opencv by providing the streaming URL of the camera in the constructor of cv2.VideoCapture.

Usually, RTSP or HTTP protocol is used by the camera to stream video. An example of IP camera streaming URL is as follows:

rtsp://192.168.1.64/1

It can be opened with OpenCV like this:

capture = cv2.VideoCapture('rtsp://192.168.1.64/1')

Most of the IP cameras have a username and password to access the video. In such case, the credentials have to be provided in the streaming URL as follows:

capture = cv2.VideoCapture('rtsp://username:[email protected]/1')

Just set Content-Type is not enough, url encode form data before send. $http.post(url, jQuery.param(data))

This question is already answered, but for the benefit of others looking at this question I'd like to add the following suggestion: Instead of doing the slicing yourself as suggested above you might also use strptime() which is (IMHO) easier to read and perhaps the preferred way to do this conversion.

import datetime
s = "20120213"
s_datetime = datetime.datetime.strptime(s, '%Y%m%d')

>>> import re
>>> st = " i think mabe 124 + <font color=\"black\"><font face=\"Times New Roman\">but I don't have a big experience it just how I see it in my eyes <font color=\"green\"><font face=\"Arial\">fun stuff"
>>> re.sub("<.*?>","",st)
" i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"
>>> 

Had this problem on windows 10, eclipse Neon Release (4.6.0) and MSYS2 installed. Eclipse kept complaining that "Program 'g++' not found in PATH” and "Program 'gcc' not found in PATH”, yet it was compiling and running my C++ code. From the command prompt, I could run g++.

Solution was to define the C++ Environmental variable for eclipse called 'PATH' to point to windows variable called 'path' also $(Path). Menus: Preferences>>C/C++>>Build>>Environment

Looks like eclipse is case sensitive with the name of this environmental, while windows doesn't care about the case.

When using moment.js, use:

var tz = moment.tz.guess();

It will return an IANA time zone identifier, such as America/Los_Angeles for the US Pacific time zone.

It is documented here.

Internally, it first tries to get the time zone from the browser using the following call:

Intl.DateTimeFormat().resolvedOptions().timeZone

If you are targeting only modern browsers that support this function, and you don't need Moment-Timezone for anything else, then you can just call that directly.

If Moment-Timezone doesn't get a valid result from that function, or if that function doesn't exist, then it will "guess" the time zone by testing several different dates and times against the Date object to see how it behaves. The guess is usually a good enough approximation, but not guaranteed to exactly match the time zone setting of the computer.

You could try replacing it with 1002 or issuing your initialization query right after opening a connection.

Using new api fetch:

const dataToSend = JSON.stringify({"email": "[email protected]", "password": "101010"});
let dataReceived = ""; 
fetch("", {
    credentials: "same-origin",
    mode: "same-origin",
    method: "post",
    headers: { "Content-Type": "application/json" },
    body: dataToSend
})
    .then(resp => {
        if (resp.status === 200) {
            return resp.json()
        } else {
            console.log("Status: " + resp.status)
            return Promise.reject("server")
        }
    })
    .then(dataJson => {
        dataReceived = JSON.parse(dataJson)
    })
    .catch(err => {
        if (err === "server") return
        console.log(err)
    })

console.log(`Received: ${dataReceived}`)                

what led me to this page is that I set within a page then the inside of an included page I did the increment

and here is the problem

so to solve such a problem, simply use scope="request" when you declare the variable or the increment

//when you set the variale add scope="request"
<c:set var="nFilters" value="${0}" scope="request"/>
//the increment, it can be happened inside an included page
<c:set var="nFilters" value="${nFilters + 1}"  scope="request" />

hope this saves your time

It is very difficult to validate Email correctly simply using HTML5 attribute "pattern". If you do not use a "pattern" someone@ will be processed. which is NOT valid email.

Using pattern="[a-zA-Z]{3,}@[a-zA-Z]{3,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}" will require the format to be [email protected] however if the sender has a format like [email protected] (or similar) will not be validated to fix this you could put pattern="[a-zA-Z]{3,}@[a-zA-Z]{3,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}" this will validate ".com.au or .net.au or alike.

However using this, it will not permit [email protected] to validate. So as far as simply using HTML5 to validate email addresses is still not totally with us. To Complete this you would use something like this:

<form>
<input id="email" type="text" name="email" pattern="[a-zA-Z]{3,}@[a-zA-Z]{3,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}" required placeholder="Enter you Email">
<br>
<input type="submit" value="Submit The Form">
</form>

or:

<form>
<input id="email" type="text" name="email" pattern="[a-zA-Z]{3,}@[a-zA-Z]{3,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}" required placeholder="Enter you Email">
<br>
<input type="submit" value="Submit The Form">
</form>

However, I do not know how to validate both or all versions of email addresses using HTML5 pattern attribute.

I suspect because of modules, which remove the need for the #import <Cocoa/Cocoa.h>.

As to where to put code that you would put in a prefix header, there is no code you should put in a prefix header. Put your imports into the files that need them. Put your definitions into their own files. Put your macros...nowhere. Stop writing macros unless there is no other way (such as when you need __FILE__). If you do need macros, put them in a header and include it.

The prefix header was necessary for things that are huge and used by nearly everything in the whole system (like Foundation.h). If you have something that huge and ubiquitous, you should rethink your architecture. Prefix headers make code reuse hard, and introduce subtle build problems if any of the files listed can change. Avoid them until you have a serious build time problem that you can demonstrate is dramatically improved with a prefix header.

In that case you can create one and pass it into clang, but it's incredibly rare that it's a good idea.

EDIT: To your specific question about a HUD you use in all your view controllers, yes, you should absolutely import it into every view controller that actually uses it. This makes the dependencies clear. When you reuse your view controller in a new project (which is common if you build your controllers well), you will immediately know what it requires. This is especially important for categories, which can make code very hard to reuse if they're implicit.

The PCH file isn't there to get rid of listing dependencies. You should still import UIKit.h or Foundation.h as needed, as the Xcode templates do. The reason for the PCH is to improve build times when dealing with really massive headers (like in UIKit).

If the pages are blank coming from SSRS, you need to tweak your report layout. This will be far more efficient than running the output through and post process to repair the side effects of a layout problem.

SSRS is very finicky when it comes to pushing the boundaries of the margins. It is easy to accidentally widen/lengthen the report just by adjusting text box or other control on the report. Check the width and height property of the report surface carefully and squeeze them as much as possible. Watch out for large headers and footers.

UPDATE 2020

With the new (yet in Editor's draft) CSS 4 properties you can achieve this by using min() and max() (also you can use clamp() as a - kind of - shorthand for both min() and max()

clamp(MIN, VAL, MAX) is resolved as max(MIN, min(VAL, MAX))

min() syntax:

min( <calc-sum># )

where 
<calc-sum> = <calc-product> [ [ '+' | '-' ] <calc-product> ]*

where 
<calc-product> = <calc-value> [ '*' <calc-value> | '/' <number> ]*

where 
<calc-value> = <number> | <dimension> | <percentage> | ( <calc-sum> )

max() syntax:

max( <calc-sum># )
    
where
<calc-sum> = <calc-product> [ [ '+' | '-' ] <calc-product> ]*
    
where  
<calc-product> = <calc-value> [ '*' <calc-value> | '/' <number> ]*

where 
<calc-value> = <number> | <dimension> | <percentage> | ( <calc-sum> )

clamp() syntax:

clamp( <calc-sum>#{3} )

where 
<calc-sum> = <calc-product> [ [ '+' | '-' ] <calc-product> ]*

where 
<calc-product> = <calc-value> [ '*' <calc-value> | '/' <number> ]*

where 
<calc-value> = <number> | <dimension> | <percentage> | ( <calc-sum> )

Snippet

.min {

Old Answer

No you can't.

margin and padding properties don't have the min/max prefixes

An approximately way would be using relative units (vh/vw), but still not min/max

And as @vigilante_stark pointed out in the answer, the CSS calc() function could be another workaround, something like these:

/* demo */

* {
  box-sizing: border-box
}

section {
  background-color: red;
  width: 50vw;
  height: 50px;
  position: relative;
}

div {
  width: inherit;
  height: inherit;
  position: absolute;
  top: 0;
  left: 0
}


/* end of demo */

.min {
  /* demo */
  border: green dashed 4px;
  /*this your min padding-left*/
  padding-left: calc(50vw + 50px);
}

.max {
  /* demo */
  border: blue solid 3px;
  /*this your max padding-left*/
  padding-left: calc(50vw + 200px);
}

<section>
  <div class="min"></div>
  <div class="max"></div>

Nodemailer is basically a module that gives you the ability to easily send emails when programming in Node.js. There are some great examples of how to use the Nodemailer module at http://www.nodemailer.com/. The full instructions about how to install and use the basic functionality of Nodemailer is included in this link.

I personally had trouble installing Nodemailer using npm, so I just downloaded the source. There are instructions for both the npm install and downloading the source.

This is a very simple module to use and I would recommend it to anyone wanting to send emails using Node.js. Good luck!

If you are using ModelViewSet, well actually you are done! It handles every things for you! You just need to put the field in your ModelSerializer and set content-type=multipart/form-data; in your client.

BUT as you know you can not send files in json format. (when content-type is set to application/json in your client). Unless you use Base64 format.

So you have two choices:

• let ModelViewSet and ModelSerializer handle the job and send the request using content-type=multipart/form-data;
• set the field in ModelSerializer as Base64ImageField (or) Base64FileField and tell your client to encode the file to Base64 and set the content-type=application/json

I would opt for a more functional approach. Since ES6 we have been given such nice tools to solve our problems, so why not use them. Let's begin with giving the checkboxes a class so we can round them up very nicely. I prefer to use a class instead of input[type="checkbox"] because now the solution is more generic and can be used also when you have more groups of checkboxes in your document.

HTML

    <input type="checkbox" class="checkbox" value=ck1 /> ck1<br />
    <input type="checkbox" class="checkbox" value=ck2 /> ck2<br />

JavaScript

function atLeastOneCheckboxIsChecked(){
    const checkboxes = Array.from(document.querySelectorAll(".checkbox"));
    return checkboxes.reduce((acc, curr) => acc || curr.checked, false);
}

When called, the function will return false if no checkbox has been checked and true if one or both is.

It works as follows, the reducer function has two arguments, the accumulator (acc) and the current value (curr). For every iteration over the array, the reducer will return true if either the accumulator or the current value is true. the return value of the previous iteration is the accumulator of the current iteration, therefore, if it ever is true, it will stay true until the end.

Changing the ng-src value is actually very simple. Like this:

<html ng-app>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.min.js"></script>
</head>
<body>
<img ng-src="{{img_url}}">
<button ng-click="img_url = 'https://farm4.staticflickr.com/3261/2801924702_ffbdeda927_d.jpg'">Click</button>
</body>
</html>

Here is a jsFiddle of a working example: http://jsfiddle.net/Hx7B9/2/

From my understanding of the Apple documentation, a selector represents the name of the method that you want to call. The nice thing about selectors is you can use them in cases where the exact method to be called varies. As a simple example, you can do something like:

SEL selec;
if (a == b) {
selec = @selector(method1)
}
else
{
selec = @selector(method2)
};
[self performSelector:selec];

Simply add this code:

if (string.Contains("search_text")) { MessageBox.Show("Message."); }

You don't necessarily need to have the parameters inside the URL.

For instance, with:

$stateProvider
.state('home', {
  url: '/',
  views: {
    '': {
      templateUrl: 'home.html',
      controller: 'MainRootCtrl'

    },
  },
  params: {
    foo: null,
    bar: null

You will be able to send parameters to the state, using either:

$state.go('home', {foo: true, bar: 1});
// or
<a ui-sref="home({foo: true, bar: 1})">Go!</a>

Of course, if you reload the page once on the home state, you will loose the state parameters, as they are not stored anywhere.

A full description of this behavior is documented here, under the params row in the state(name, stateConfig) section.

Nobody seems to touch upon the fact that if you have many different 32-bit applications, the wow64 subsystem can map them anywhere in memory above 4G, so on a 64-bit windows with sufficient memory, you can run many more 32-bit applications than on a native 32-bit system.

EDIT: I noticed a few downvotes and took another look at this Q&A. Most people seem to miss that the OP asked for fields to be dynamically selected based on the caller-provided list of fields. You can't do this with the statically-defined json struct tag.

If what you want is to always skip a field to json-encode, then of course use json:"-" to ignore the field (also note that this is not required if your field is unexported - those fields are always ignored by the json encoder). But that is not the OP's question.

To quote the comment on the json:"-" answer:

This [the json:"-" answer] is the answer most people ending up here from searching would want, but it's not the answer to the question.

I'd use a map[string]interface{} instead of a struct in this case. You can easily remove fields by calling the delete built-in on the map for the fields to remove.

That is, if you can't query only for the requested fields in the first place.

For those who still do not understand.

>>> a = iter(list(range(10)))
>>> for i in a:
...    print(i)
...    next(a)
... 
0 # print(i) printed this
1 # next(a) printed this
2 # print(i) printed this
3 # next(a) printed this
4 # print(i) printed this
5 # next(a) printed this
6 # print(i) printed this
7 # next(a) printed this
8 # print(i) printed this
9 # next(a) printed this

As others have already said, next increases the iterator by 1 as expected. Assigning its returned value to a variable doesn't magically changes its behaviour.

I see two problems:

DOUBLE(10) precision definitions need a total number of digits, as well as a total number of digits after the decimal:

DOUBLE(10,8) would make be ten total digits, with 8 allowed after the decimal.

Also, you'll need to specify your id column as a key :

CREATE TABLE transactions( 
id int NOT NULL AUTO_INCREMENT, 
location varchar(50) NOT NULL, 
description varchar(50) NOT NULL, 
category varchar(50) NOT NULL, 
amount double(10,9) NOT NULL, 
type varchar(6) NOT NULL,  
notes varchar(512), 
receipt int(10), 
PRIMARY KEY(id) );

Please check Michael answer and vote for it. It is the right way to check open ports. Netstat and other tools are not any use if you are developing services or daemons. For instance, I am crating modbus TCP server and client services for an industrial network. The services can listen to any port, but the question is whether that port is open? The program is going to be used in different places, and I cannot check them all manually, so this is what I did:

from contextlib import closing
import socket
class example:
    def __init__():

       self.machine_ip = socket.gethostbyname(socket.gethostname())
       self.ready:bool = self.check_socket()

    def check_socket(self)->bool:
        result:bool = True
        with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as sock:
        modbus_tcp_port:int = 502
        if not sock.connect_ex((self.machine_ip, modbus_tcp_port)) == 0:
            result = False
        return result

The following works for me, although I did not test every single device there is to test :-)

$('body, html').css('overflow-y', 'hidden');
$('html, body').animate({
    scrollTop:0
}, 0);

Answer for PyCharm 2016.1 on OSX: (This is an update to the answer by @GeorgeWilliams993's answer above, but I don't have the rep yet to make comments.)

Go to Pycharm menu --> Preferences --> Project: (projectname) --> Project Interpreter

At the top is a popup for "Project Interpreter," and to the right of it is a button with ellipses (...) - click on this button for a different popup and choose "More" (or, as it turns out, click on the main popup and choose "Show All").

This shows a list of interpreters, with one selected. At the bottom of the screen are a set of tools... pick the rightmost one:

Now you should see all the paths pycharm is searching to find imports, and you can use the "+" button at the bottom to add a new path.

I think the most significant difference from @GeorgeWilliams993's answer is that the gear button has been replaced by a set of ellipses. That threw me off.

If you are using bootstrap and font-awesome then it is easy, no need to write a single line of new code, just add fa-Nx, as big you want, See the demo

<span class="glyphicon glyphicon-globe"></span>
<span class="glyphicon glyphicon-globe fa-lg"></span>
<span class="glyphicon glyphicon-globe fa-2x"></span>
<span class="glyphicon glyphicon-globe fa-3x"></span>
<span class="glyphicon glyphicon-globe fa-4x"></span>
<span class="glyphicon glyphicon-globe fa-5x"></span>

Alternatively you could use a for loop as shown in the Groovy Docs:

def map = ['a':1, 'b':2, 'c':3]
for ( e in map ) {
    print "key = ${e.key}, value = ${e.value}"
}

/*
Result:
key = a, value = 1
key = b, value = 2
key = c, value = 3
*/

One benefit of using a for loop as opposed to an each closure is easier debugging, as you cannot hit a break point inside an each closure (when using Netbeans).

Hello guys Most of the codes you will find will return you server ip address not client ip address .however this code returns correct client ip address.Give it a try. For More info just check this

https://www.youtube.com/watch?v=Nkf37DsxYjI

for getting your local ip address using javascript you can use put this code inside your script tag

<script>
    var RTCPeerConnection = /*window.RTCPeerConnection ||*/
     window.webkitRTCPeerConnection || window.mozRTCPeerConnection;

         if (RTCPeerConnection) (function () {
             var rtc = new RTCPeerConnection({ iceServers: [] });
             if (1 || window.mozRTCPeerConnection) {      
                 rtc.createDataChannel('', { reliable: false });
             };

             rtc.onicecandidate = function (evt) {

                 if (evt.candidate)
                     grepSDP("a=" + evt.candidate.candidate);
             };
             rtc.createOffer(function (offerDesc) {
                 grepSDP(offerDesc.sdp);
                 rtc.setLocalDescription(offerDesc);
             }, function (e) { console.warn("offer failed", e); });


             var addrs = Object.create(null);
             addrs["0.0.0.0"] = false;
             function updateDisplay(newAddr) {
                 if (newAddr in addrs) return;
                 else addrs[newAddr] = true;
                 var displayAddrs = Object.keys(addrs).filter(function
(k) { return addrs[k]; });
                 document.getElementById('list').textContent =
displayAddrs.join(" or perhaps ") || "n/a";
             }

             function grepSDP(sdp) {
                 var hosts = [];
                 sdp.split('\r\n').forEach(function (line) { 
                     if (~line.indexOf("a=candidate")) {   
                         var parts = line.split(' '),   
                             addr = parts[4],
                             type = parts[7];
                         if (type === 'host') updateDisplay(addr);
                     } else if (~line.indexOf("c=")) {      
                         var parts = line.split(' '),
                             addr = parts[2];
                         updateDisplay(addr);
                     }
                 });
             }
         })(); else
         {
             document.getElementById('list').innerHTML = "<code>ifconfig| grep inet | grep -v inet6 | cut -d\" \" -f2 | tail -n1</code>";
             document.getElementById('list').nextSibling.textContent = "In Chrome and Firefox your IP should display automatically, by the power of WebRTCskull.";

         }




</script>
<body>
<div id="list"></div>
</body>

and For getting your public ip address you can use put this code inside your script tag

  function getIP(json) {
    document.write("My public IP address is: ", json.ip);
  }


<script type="application/javascript" src="https://api.ipify.org?format=jsonp&callback=getIP"></script>

convert(varchar, column_name1) + (varchar, column_name)

1. Choose the border style as not rounded

2. Set your height

in your viewWillAppear set the corners as round

yourUITextField.borderStyle = UITextBorderStyleRoundedRect;

3. Enjoy your round and tall UITextField

See this fiddle.
Basically, you want to get the values of your option-tags, but you always try to get the value of your select-node with $("#first").val().

So we have to select the option-tags and we will utilize jQuerys selectors:

$("#first option").each(function() {
    console.log($(this).val());
});

$("#first option") selects every option which is a child of the element with the id first.

I got same error because I was trying to run on

XXX-Macmini:Python-Project XXX.XXX$ from classDemo import MyClass

from: can't read /var/mail/classDemo

To solve this, type command python and when you get these >>> then run any python commands

>>>from classDemo import MyClass
>>>f = MyClass()

You need to make the markup right

<button type="button" id="example" class="btn btn-primary">example</button>

Then, one way is to attach the close-handler inside the element itself, the following works :

$(document).ready(function() {
    $("#example").popover({
        placement: 'bottom',
        html: 'true',
        title : '<span class="text-info"><strong>title</strong></span>'+
                '<button type="button" id="close" class="close" onclick="$(&quot;#example&quot;).popover(&quot;hide&quot;);">&times;</button>',
        content : 'test'
    });
});  

The best that worked for me:

AndroidManifest

<receiver android:name="com.AEDesign.communication.WifiReceiver" >
   <intent-filter android:priority="100">
      <action android:name="android.net.wifi.STATE_CHANGE" />
   </intent-filter>
</receiver>

BroadcastReceiver class

public class WifiReceiver extends BroadcastReceiver {

   @Override
   public void onReceive(Context context, Intent intent) {

      NetworkInfo info = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
      if(info != null && info.isConnected()) {
        // Do your work. 

        // e.g. To check the Network Name or other info:
        WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
        WifiInfo wifiInfo = wifiManager.getConnectionInfo();
        String ssid = wifiInfo.getSSID();
      }
   }
}

Permissions

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

I think this should work, irrespective of how often and when you run it ...

date -d "yesterday 13:00" '+%Y-%m-%d'

Another way is to use the subplots function and pass the width ratio with gridspec_kw:

import numpy as np
import matplotlib.pyplot as plt 

# generate some data
x = np.arange(0, 10, 0.2)
y = np.sin(x)

# plot it
f, (a0, a1) = plt.subplots(1, 2, gridspec_kw={'width_ratios': [3, 1]})
a0.plot(x, y)
a1.plot(y, x)

f.tight_layout()
f.savefig('grid_figure.pdf')

This recently worked for me. You just need to add to your packages, so that the package manager would be aware of the packages:

1. Add the Sublime Text 2 Repository to your Synaptic Package Manager:

   sudo add-apt-repository ppa:webupd8team/sublime-text-2
   

2. Update

   sudo apt-get update
   

3. Install Sublime Text:

   sudo apt-get install sublime-text
   

In PowerShell v3, have a look at the Invoke-WebRequest and Invoke-RestMethod e.g.:

$msg = Read-Host -Prompt "Enter message"
$encmsg = [System.Web.HttpUtility]::UrlEncode($msg)
Invoke-WebRequest -Uri "http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$encmsg&encoding=windows-1255"

This is one of the points in C that can be confusing at first, but the C standard only specifies a minimum range for integer types that is guaranteed to be supported. int is guaranteed to be able to hold -32767 to 32767, which requires 16 bits. In that case, int, is 2 bytes. However, implementations are free to go beyond that minimum, as you will see that many modern compilers make int 32-bit (which also means 4 bytes pretty ubiquitously).

The reason your book says 2 bytes is most probably because it's old. At one time, this was the norm. In general, you should always use the sizeof operator if you need to find out how many bytes it is on the platform you're using.

To address this, C99 added new types where you can explicitly ask for a certain sized integer, for example int16_t or int32_t. Prior to that, there was no universal way to get an integer of a specific width (although most platforms provided similar types on a per-platform basis).

Here is How I close my alertDialog

lv_three.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
                GetTalebeDataUser clickedObj = (GetTalebeDataUser) parent.getItemAtPosition(position);
                alertDialog.setTitle(clickedObj.getAd());
                alertDialog.setMessage("Ögrenci Bilgileri Güncelle?");
                alertDialog.setIcon(R.drawable.ic_info);
                // Setting Positive "Yes" Button
                alertDialog.setPositiveButton("Tamam", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        // User pressed YES button. Write Logic Here
                    }
                });
                alertDialog.setNegativeButton("Iptal", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        //alertDialog.
                        alertDialog.setCancelable(true); // HERE

                    }
                });
                alertDialog.show();
                return true;
            }
        });

You can use it in swift 5

SWIFT 5

import UIKit

extension UIColor {
    static func hexStringToUIColor (hex:String) -> UIColor {
        var cString:String = hex.trimmingCharacters(in: .whitespacesAndNewlines).uppercased()

        if (cString.hasPrefix("#")) {
            cString.remove(at: cString.startIndex)
        }

        if ((cString.count) != 6) {
            return UIColor.gray
        }

        var rgbValue:UInt32 = 0
        Scanner(string: cString).scanHexInt32(&rgbValue)

        return UIColor(
            red: CGFloat((rgbValue & 0xFF0000) >> 16) / 255.0,
            green: CGFloat((rgbValue & 0x00FF00) >> 8) / 255.0,
            blue: CGFloat(rgbValue & 0x0000FF) / 255.0,
            alpha: CGFloat(1.0)
        )
    }
}

I tried invalidating cache, it didnt work for me.

However, I tried removing the jdk from Platform Settings and added it back and it worked.

Here's how to do it.

I wasn't satisfied with what was offered, so here's my proposal, using jQuery :

            <div id="playlist">
                <audio id="player" controls preload="metadata" volume="1">
                  <source src="" type="audio/mpeg">
                  Sorry, this browser doesn't support HTML 5.0
                </audio>
                <ul></ul>
            </div>

            <script>
                var folder = "audio";
                var playlist = [
                    "example1.mp3",
                    "example2.mp3"
                ];
                for (var i in playlist) {
                    jQuery('#playlist ul').append('<li>'+playlist[i]+'</li>');
                }

                var player = document.getElementById('player');
                var playing = playlist[0];
                player.src = folder + '/' + playing;

                function display(id) {
                    var list = jQuery('#playlist ul').children();
                    list.removeClass('playing');
                    jQuery(list[id]).addClass('playing');
                }

                display(0);

                player.onended = function(){
                    var ind_next = playlist.indexOf(playing) + 1;

                    if (ind_next !== 0) {
                        player.src = folder + '/' + playlist[ind_next];
                        playing = player.src;
                        display(ind_next)
                        player.play();
                    }
                }
            </script>

You only have to edit the playlist array, and you're done

I've heard in my degree classes that a HashTable will place a new entry into the 'next available' bucket if the new Key entry collides with another.

This is actually not true, at least for the Oracle JDK (it is an implementation detail that could vary between different implementations of the API). Instead, each bucket contains a linked list of entries prior to Java 8, and a balanced tree in Java 8 or above.

then how would the HashTable still return the correct Value if this collision occurs when calling for one back with the collision key?

It uses the equals() to find the actually matching entry.

If I implement my own hashing function and use it as part of a look-up table (i.e. a HashMap or Dictionary), what strategies exist for dealing with collisions?

There are various collision handling strategies with different advantages and disadvantages. Wikipedia's entry on hash tables gives a good overview.

Well, not sure if this is what You mean but Posgres normally support "dummy" ETL syntax. I created one empty column in table and then needed to fill it by calculated records depending on values in row.

UPDATE table01
SET column03 = column01*column02; /*e.g. for multiplication of 2 values*/

1. It is so dummy I suspect it is not what You are looking for.
2. Obviously it is not dynamic, you run it once. But no obstacle to get it into trigger.

I tried with cygwin & gnuwin, and didn't worked for me, I guess because the makefile used mainly specific linux code.

What it worked was use Ubuntu Bash for Windows 10. This is a Marvel if you come from MAC as it is my case:

1. To install the Ubuntu Bash: https://itsfoss.com/install-bash-on-windows/
2. Once in the console, to install make simply type "make" and it gives the instructions to download it.

Extras:

1. Useful enable copy / paste on bash: Copy Paste in Bash on Ubuntu on Windows
2. In my case the make called Maven, so I have to install it as well: https://askubuntu.com/questions/722993/unable-to-locate-package-maven
3. To access windows filesystem C: drive, for example: "cd /mnt/c/"

Hope it helps

Shorter version:

$('#multiselect1').multiselect({
    ...
    onChange: function() {
        console.log($('#multiselect1').val());
    }
}); 

The Linq extension method Any could work for you...

buildingStatus.Any(item => item.GetCharValue() == v.Status)

for those who want some official document to confirm the behavior

Variables in make can come from the environment in which make is run. Every environment variable that make sees when it starts up is transformed into a make variable with the same name and value. However, an explicit assignment in the makefile, or with a command argument, overrides the environment. (If the ‘-e’ flag is specified, then values from the environment override assignments in the makefile.

Enter this site: https://rpmfind.net/linux/rpm2html/search.php?query=ca-certificates , get your ca-certificate, for yout SO, for example: ftp://rpmfind.net/linux/fedora/linux/updates/24/x86_64/c/ca-certificates-2016.2.8-1.0.fc24.noarch.rpm << CentOS. Copy url of download and paste in url: wget your_url_donwload_ca-ceritificated.rpm now, install yout rpm:

rpm2cpio your_url_donwload_ca-ceritificated.rpm | cpio -idmv

now restart your service: my example this command:

sudo service2 httpd restart

very great good look

In a PRE tag -and in most other HTML tags- plain text for a batch file that uses the output redirection characters (< and >) will break the HTML, but here is my tip: anything goes in a TEXTAREA element -it will not break the HTML, mainly because we are inside a control instanced and handled by the OS, and therefore its content are not being parsed by the HTML engine.

As an example, say I want to highlight the syntax of my batch file using javascript. I simply paste the code in a textarea without worrying about the HTML reserved characters, and have the script process the innerHTML property of the textarea, which evaluates to the text with the HTML reserved characters replaced by their corresponding ISO-8859-1 entities.

Browsers will escape special characters automatically when you retrieve the innerHTML (and outerHTML) property of an element. Using a textarea (and who knows, maybe an input of type text) just saves you from doing the conversion (manually or through code).

I use this trick to test my syntax highlighter, and when I'm done authoring and testing, I simply hide the textarea from view.

For Jest 24.9+, you can also set the timeout from the command line by adding --testTimeout.

Here's an excerpt from its documentation:

--testTimeout=<number>
Default timeout of a test in milliseconds. Default value: 5000.

I prefer a popup.

$shell = new-object -comobject "WScript.Shell"
$choice = $shell.popup("Insert question here",0,"Popup window title",4+32)

If $choice equals 6, the answer was Yes If $choice equals 7, the answer was No

In VS 2017, i have checked SQL Server Data Tools during the installation and it doesn't help. So I have downloaded and installed Microsoft.RdlcDesigner.vsix

Now it works.

UPDATE

Another way is to use Extensions and Updates.

Go to Tools > Extensions and Updates choose Online then search for Microsoft Rdlc Report Designer for Visual studio and click Download. It need to close VS to start installation. After installation you will be able to use rdlc designer.

Hope this helps!

        int counter = Convert.ToInt32(Console.ReadLine());
        //Here is your variable
        Console.WriteLine("The numbers start from");
        do
        {
            counter++;

$("#YourElementID").css("display","block");

Edit: or as dave thieben points out in his comment below, you can do this as well:

$("#YourElementID").css({ display: "block" });

.toString() is available, or just add "" to the end of the int

var x = 3,
    toString = x.toString(),
    toConcat = x + "";

Angular is simply JavaScript at the core.

In short:

1. Go to Edit > Preferences
2. Choose SQL Editor
3. Under SQL Execution, check Treat BINARY/VARBINARY as nonbinary character string
4. Restart MySQL Workbench (you will not be prompted or informed of this requirement).

In MySQL Workbench 6.0+

1. Go to Edit > Preferences
2. Choose SQL Queries
3. Under Query Results, check Treat BINARY/VARBINARY as nonbinary character string
4. It's not mandatory to restart MySQL Workbench (you will not be prompted or informed of this requirement).*

With this setting you will be able to concatenate fields without getting blobs.

I think this applies to versions 5.2.22 and later and is the result of this MySQL bug.

Disclaimer: I don't know what the downside of this setting is - maybe when you are selecting BINARY/VARBINARY values you will see it as plain text which may be misleading and/or maybe it will hinder performance if they are large enough?

I enclosed C++ code for grabbing frames. It requires OpenCV version 2.0 or higher. The code uses cv::mat structure which is preferred to old IplImage structure.

#include "cv.h"
#include "highgui.h"
#include <iostream>

int main(int, char**) {
    cv::VideoCapture vcap;
    cv::Mat image;

    const std::string videoStreamAddress = "rtsp://cam_address:554/live.sdp"; 
    /* it may be an address of an mjpeg stream, 
    e.g. "http://user:pass@cam_address:8081/cgi/mjpg/mjpg.cgi?.mjpg" */

    //open the video stream and make sure it's opened
    if(!vcap.open(videoStreamAddress)) {
        std::cout << "Error opening video stream or file" << std::endl;
        return -1;
    }

    //Create output window for displaying frames. 
    //It's important to create this window outside of the `for` loop
    //Otherwise this window will be created automatically each time you call
    //`imshow(...)`, which is very inefficient. 
    cv::namedWindow("Output Window");

    for(;;) {
        if(!vcap.read(image)) {
            std::cout << "No frame" << std::endl;
            cv::waitKey();
        }
        cv::imshow("Output Window", image);
        if(cv::waitKey(1) >= 0) break;
    }   
}

Update You can grab frames from H.264 RTSP streams. Look up your camera API for details to get the URL command. For example, for an Axis network camera the URL address might be:

// H.264 stream RTSP address, where 10.10.10.10 is an IP address 
// and 554 is the port number
rtsp://10.10.10.10:554/axis-media/media.amp

// if the camera is password protected
rtsp://username:[email protected]:554/axis-media/media.amp

For win7 chrome can be found at:

For VS2017 click the little down arrow next to the run in debug/release mode button to find the "browse with..." option.

>>> from datetime import datetime

>>>  a = datetime.now()

# wait a bit 
>>> b = datetime.now()

>>> d = b - a # yields a timedelta object
>>> d.seconds
7

(7 will be whatever amount of time you waited a bit above)

I find datetime.datetime to be fairly useful, so if there's a complicated or awkward scenario that you've encountered, please let us know.

EDIT: Thanks to @WoLpH for pointing out that one is not always necessarily looking to refresh so frequently that the datetimes will be close together. By accounting for the days in the delta, you can handle longer timestamp discrepancies:

>>> a = datetime(2010, 12, 5)
>>> b = datetime(2010, 12, 7)
>>> d = b - a
>>> d.seconds
0
>>> d.days
2
>>> d.seconds + d.days * 86400
172800

An excellent plug-in is jscrollpane

As @AliK mentioned, this can be done easily by looking at the value of the submit buttons.

When you submit a form, unset variables will evaluate false. If you set both submit buttons to be part of the same form, you can just check and see which button has been set.

HTML:

<form action="handle_user.php" method="POST" />
  <input type="submit" value="Save" name="save" />
  <input type="submit" value="Submit for Approval" name="approve" />
</form>

PHP

if($_POST["save"]) {
  //User hit the save button, handle accordingly
}
//You can do an else, but I prefer a separate statement
if($_POST["approve"]) {
  //User hit the Submit for Approval button, handle accordingly
}

EDIT

Related:

• 2x submit buttons to action different URL
• Submit form to another page (which is different from the page used in ACTION)

That is not possible without intercepting addEventListener calls and keep track of the listeners or use a library that allows such features unfortunately. It would have been if the listeners collection was accessible but the feature wasn't implemented.

The closest thing you can do is to remove all listeners by cloning the element, which will not clone the listeners collection.

Note: This will also remove listeners on element's children.

var el = document.getElementById('el-id'),
    elClone = el.cloneNode(true);

el.parentNode.replaceChild(elClone, el);

You simply need to make cab a string:

cab = '6176'

As the error message states, you cannot do <int> in <string>:

>>> 1 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>> 

because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").

In fact, Python only allows you to use the in operator with a right operand of type string if the left operand is also of type string:

>>> '1' in '123'  # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list
>>>
>>> 1.0 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not float
>>>

Use the .c_str() method for const char *.

You can use &mystring[0] to get a char * pointer, but there are a couple of gotcha's: you won't necessarily get a zero terminated string, and you won't be able to change the string's size. You especially have to be careful not to add characters past the end of the string or you'll get a buffer overrun (and probable crash).

There was no guarantee that all of the characters would be part of the same contiguous buffer until C++11, but in practice all known implementations of std::string worked that way anyway; see Does “&s[0]” point to contiguous characters in a std::string?.

Note that many string member functions will reallocate the internal buffer and invalidate any pointers you might have saved. Best to use them immediately and then discard.

ah homework...

So wait, you need to deduct the balance of items in stock from the total number of those items that have been ordered? I have to tell you that sounds a bit backwards. Generally I think people do it the other way round. Deduct the total number of items ordered from the balance.

If you really need to do that though... Assuming that ITEM is unique in stock_bal...

SELECT s.ITEM, SUM(m.QTY) - s.QTY AS result
FROM stock_bal s
INNER JOIN master_table m ON m.ITEM = s.ITEM
GROUP BY s.ITEM, s.QTY

You can also use jQuery's delay() method instead of setTimeout(). It'll give you much more readable code. Here's an example from the docs:

$( "#foo" ).slideUp( 300 ).delay( 800 ).fadeIn( 400 );

The only limitation (that I'm aware of) is that it doesn't give you a way to clear the timeout. If you need to do that then you're better off sticking with all the nested callbacks that setTimeout thrusts upon you.

you need to return when the readystate==4 e.g.

function httpGet(theUrl)
{
    if (window.XMLHttpRequest)
    {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
    }
    else
    {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange=function()
    {
        if (xmlhttp.readyState==4 && xmlhttp.status==200)
        {
            return xmlhttp.responseText;
        }
    }
    xmlhttp.open("GET", theUrl, false );
    xmlhttp.send();    
}

What I did is first check what are the running processes by

SELECT * FROM pg_stat_activity WHERE state = 'active';

Find the process you want to kill, then type:

SELECT pg_cancel_backend(<pid of the process>)

This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.

If the process cannot be killed, try:

SELECT pg_terminate_backend(<pid of the process>)

Use a semaphore with a count that is equal to the number of readers. Let each reader take one count of the semaphore in order to read, that way they can all read at the same time. Then let the writer take ALL the semaphore counts prior to writing. This causes the writer to wait for all reads to finish and then block out reads while writing.

You can access the USB drive by its drive letter. To know the drive letter you can run this command:

C:\>wmic logicaldisk where drivetype=2 get deviceid, volumename, description

From here you will get the drive letter (Device ID) of your USB drive.

For example if its F: then run the following command in command prompt to see its contents:

C:\> F:

F:\> dir

You can't detect the codepage

This is clearly false. Every web browser has some kind of universal charset detector to deal with pages which have no indication whatsoever of an encoding. Firefox has one. You can download the code and see how it does it. See some documentation here. Basically, it is a heuristic, but one that works really well.

Given a reasonable amount of text, it is even possible to detect the language.

Here's another one I just found using Google:

Xml declaration is optional so your xml is well-formed without it. But it is recommended to use it so that wrong assumptions are not made by the parsers, specifically about the encoding used.

overflow:hidden 

does not always mean that the element is hidden or non existent in the DOM, it means that the overflowing chars that do not fit in the element are being trimmed. Basically it means that do not show scrollbar even if it should be showed, so in your case the link with text

Plastic Spiral Bind

could possibly be shown as "Plastic Spir..." or similar. So it is possible, that this linkText indeed is non existent.

So you can probably try:

driver.findElement(By.partialLinkText("Plastic ")).click();

or xpath:

//a[contains(@title, \"Plastic Spiral Bind\")]

add this to your css:

.carousel-inner > .item > img, .carousel-inner > .item > a > img {
    width: 100%;
}

In Perl, use Regexp::Common which will allow you to assemble a finely-tuned regular expression for your particular number format. If you are not using Perl, the generated regular expression can still typically be used by other languages.

Printing the result of generating the example regular expressions in Regexp::Common::Number:

$ perl -MRegexp::Common=number -E 'say $RE{num}{int}'
(?:(?:[-+]?)(?:[0123456789]+))

$ perl -MRegexp::Common=number -E 'say $RE{num}{real}'
(?:(?i)(?:[-+]?)(?:(?=[.]?[0123456789])(?:[0123456789]*)(?:(?:[.])(?:[0123456789]{0,}))?)(?:(?:[E])(?:(?:[-+]?)(?:[0123456789]+))|))

$ perl -MRegexp::Common=number -E 'say $RE{num}{real}{-base=>16}'
(?:(?i)(?:[-+]?)(?:(?=[.]?[0123456789ABCDEF])(?:[0123456789ABCDEF]*)(?:(?:[.])(?:[0123456789ABCDEF]{0,}))?)(?:(?:[G])(?:(?:[-+]?)(?:[0123456789ABCDEF]+))|))

First, You have to install the Android Studio and Xcode to create phone emulator.

In VSCode you can use the Android IOS Emulator plugin to set the path of emulator to run.

You can use HeaderTemplate property to setup the head programatically or use ListView instead if you are using .NET 3.5.

Personally, I prefer ListView over GridView and DetailsView if possible, it gives you more control over your html.

There's no goto instruction in the Python programming language. You'll have to write your code in a structured way... But really, why do you want to use a goto? that's been considered harmful for decades, and any program you can think of can be written without using goto.

Of course, there are some cases where an unconditional jump might be useful, but it's never mandatory, there will always exist a semantically equivalent, structured solution that doesn't need goto.

For my example :first 'MainActivity' implements 'View.OnClickListener' than start the code ....

@Override

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    init();}


public void init(){

    foryou = (Button) this.findViewById(R.id.btn_foryou);
    following = (Button) findViewById(R.id.btn_following);
    popular = (Button) findViewById(R.id.btn_popular);
    watching = (Button) findViewById(R.id.btn_continuewatching);
    mProgress = (ProgressBar) findViewById(R.id.pb);

    foryou.setOnClickListener(this);
    following.setOnClickListener(this);
    popular.setOnClickListener(this);
    watching.setOnClickListener(this);
    mProgress.setOnClickListener(this);
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.btn_foryou:
            foryou.setPaintFlags(foryou.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_following:
            following.setPaintFlags(following.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_popular:
            popular.setPaintFlags(popular.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_continuewatching:
            watching.setPaintFlags(watching.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_5:
            // foryou.setPaintFlags(foryou.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        default:
            foryou.setPaintFlags(foryou.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

    }
}

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

Update your setuptools, too.

pip install setuptools --upgrade

If that fails too, you could try with additional --force flag.

I suggest:

writeLines(c("Hello","World"), "output.txt")

It is shorter and more direct than the current accepted answer. It is not necessary to do:

fileConn<-file("output.txt")
# writeLines command using fileConn connection
close(fileConn)

Because the documentation for writeLines() says:

If the con is a character string, the function calls file to obtain a file connection which is opened for the duration of the function call.

# default settings for writeLines(): sep = "\n", useBytes = FALSE
# so: sep = "" would join all together e.g.

this way is a bit more flexible than using all():

my_list = [[1, 2, 0], [1, 2, 0], [1, 2, 0]]
all_zeros = False if False in [x[2] == 0 for x in my_list] else True
any_zeros = True if True in [x[2] == 0 for x in my_list] else False

or more succinctly:

all_zeros = not False in [x[2] == 0 for x in my_list]
any_zeros = 0 in [x[2] for x in my_list]

I am assuming you want to display this as part of the player.

This site breaks down how to get both the current and total time regardless of how you want to display it though using jQuery:

http://dev.opera.com/articles/view/custom-html5-video-player-with-css3-and-jquery/

This will also cover how to set it to a specific div. As philip has already mentioned, .currentTime will give you where you are in the video.

The li tag has a property called list-style-position. This makes your bullets inside or outside the list. On default, it’s set to inside. That makes your text wrap around it. If you set it to outside, the text of your li tags will be aligned.

The downside of that is that your bullets won't be aligned with the text outside the ul. If you want to align it with the other text you can use a margin.

ul li {
    /*
     * We want the bullets outside of the list,
     * so the text is aligned. Now the actual bullet
     * is outside of the list’s container
     */
    list-style-position: outside;

    /*
     * Because the bullet is outside of the list’s
     * container, indent the list entirely
     */
    margin-left: 1em;
}

Edit 15th of March, 2014 Seeing people are still coming in from Google, I felt like the original answer could use some improvement

• Changed the code block to provide just the solution
• Changed the indentation unit to em’s
• Each property is applied to the ul element
• Good comments :)

try out this if you want to assign value to object and it is showing this error in angular..

crate object in construtor

this.modelObj = new Model(); //<---------- after declaring object above

You parse the field from the database as usual.

Then let's say you put it in a variable called $title, you just

<html>
<head>
<title>Ultan.me - <?php echo htmlspecialchars($title);?></title>
</head>

EDIT:

I see your problem. You have to set $title BEFORE using it. That is, you should query the database before <title>...

Well to solve the problems of master password - the best approach is not to store the password anywhere, the application should encrypt passwords for itself - so that only it can decrypt them. So if I was using a .config file I would do the following, mySettings.config:

encryptTheseKeys=secretKey,anotherSecret

secretKey=unprotectedPasswordThatIputHere

anotherSecret=anotherPass

someKey=unprotectedSettingIdontCareAbout

so I would read in the keys that are mentioned in the encryptTheseKeys, apply the Brodwalls example from above on them and write them back to the file with a marker of some sort (lets say crypt:) to let the application know not to do it again, the output would look like this:

encryptTheseKeys=secretKey,anotherSecret

secretKey=crypt:ii4jfj304fjhfj934fouh938

anotherSecret=crypt:jd48jofh48h

someKey=unprotectedSettingIdontCareAbout

Just make sure to keep the originals in your own secure place...

Just converting the OP's own solution into an answer:

def find_between(s, start, end):
  return (s.split(start))[1].split(end)[0]

The vimrc file in Ubuntu (12.04 (Precise Pangolin)): I tried :scriptnames in Vim, and it shows both /usr/share/vim/vimrc and ~/.vimrc.

But I had manually created ~/.vimrc.

a one-liner: ' '.join(sub[:1].upper() + sub[1:] for sub in text.split(' '))

SELECT * from employees
WHERE NOT EXISTS (SELECT name FROM eotm_dyn)

Never returns any records unless eotm_dyn is empty. You need to some kind of criteria on SELECT name FROM eotm_dyn like

SELECT * from employees
WHERE NOT EXISTS (
    SELECT name FROM eotm_dyn WHERE eotm_dyn.employeeid = employees.employeeid
)

assuming that the two tables are linked by a foreign key relationship. At this point you could use a variety of other options including a LEFT JOIN. The optimizer will typically handle them the same in most cases, however.

You just need to add [FromUri] before parameter, looks like:

GetCategories([FromUri] int[] categoryIds)

And send request:

/Categories?categoryids=1&categoryids=2&categoryids=3 

This is how I fixed it. in Visual Studio Code's terminal, First cache clean

npm cache clean --force

Then updated cli

ng update @angular/cli

If any module missing after this, use below command

npm install

use like this :-

gridview1.DataSource = ds.Tables[0]; <-- Use index or your table name which you want to bind
gridview1.DataBind();

I hope it helps!!

For me it was very important to get email logging working. After some time I discover that this need only 2 lines of code more in Atif example.

public class HandleErrorWithElmahAttribute : HandleErrorAttribute
{
    static ElmahMVCMailModule error_mail_log = new ElmahMVCMailModule();

    public override void OnException(ExceptionContext context)
    {
        error_mail_log.Init(HttpContext.Current.ApplicationInstance);
        [...]
    }
    [...]
}

I hope this will help someone :)

While @jackofallcode answer is correct, it can be written in one line:

((RelativeLayout.LayoutParams) viewToLayout.getLayoutParams()).addRule(RelativeLayout.BELOW, R.id.below_id);

XSD defines a schema which is a definition of how an XML document can be structured. You can use it to check that a given XML document is valid and follows the rules you've laid out in the schema.

WSDL is a XML document that describes a web service. It shows which operations are available and how data should be structured to send to those operations.

WSDL documents have an associated XSD that show what is valid to put in a WSDL document.

The following steps can be followed

1) Download Jquery by clicking on this link DOWNLOAD

2) Copy the js file into your root web directory eg. www.test.com/jquery-1.3.2.min.js

3) In your index.php or index.html between the head tags include the following code, and then JQuery will be installed.

<script type="text/javascript" src="jquery-1.3.2.min.js"></script>

The most simple solution for me has been to:

1)Select the Range and copy it (ctrl+c)

2)Create a new text file (anywhere, it will be deleted soon), open the text file and then paste in the excel information (ctrl+v)

3)Now that the information in Excel is in the text file, perform a select all in the text file (ctrl+a), and then copy (ctrl+c)

4)Go to the beginning of the original range in step 1, and paste over that old information from the copy in step 3.

DONE! No more false blanks! (you can now delete the temp text file)

You can use the overloads method RedirectToAction(string actionName, string controllerName);

Example:

RedirectToAction(nameof(HomeController.Index), "Home");

Another solution as seen here:

find var/log/ -iname "anaconda.*" -exec tar -cvzf file.tar.gz {} +

An alternative is to use OFFSET:

Assuming the column value is stored in B1, you can use the following

C1 = OFFSET(A1, 0, B1 - 1)

This works by:

a) taking a base cell (A1)
b) adding 0 to the row (keeping it as A)
c) adding (A5 - 1) to the column

You can also use another value instead of 0 if you want to change the row value too.

The Base64.Encoder.encodeToString method automatically uses the ISO-8859-1 character set.

For an encryption utility I am writing, I took the input string of cipher text and Base64 encoded it for transmission, then reversed the process. Relevant parts shown below. NOTE: My file.encoding property is set to ISO-8859-1 upon invocation of the JVM so that may also have a bearing.

static String getBase64EncodedCipherText(String cipherText) {
    byte[] cText = cipherText.getBytes();
    // return an ISO-8859-1 encoded String
    return Base64.getEncoder().encodeToString(cText);
}

static String getBase64DecodedCipherText(String encodedCipherText) throws IOException {
    return new String((Base64.getDecoder().decode(encodedCipherText)));
}

public static void main(String[] args) {
    try {
        String cText = getRawCipherText(null, "Hello World of Encryption...");

        System.out.println("Text to encrypt/encode: Hello World of Encryption...");
        // This output is a simple sanity check to display that the text
        // has indeed been converted to a cipher text which 
        // is unreadable by all but the most intelligent of programmers.
        // It is absolutely inhuman of me to do such a thing, but I am a
        // rebel and cannot be trusted in any way.  Please look away.
        System.out.println("RAW CIPHER TEXT: " + cText);
        cText = getBase64EncodedCipherText(cText);
        System.out.println("BASE64 ENCODED: " + cText);
        // There he goes again!!
        System.out.println("BASE64 DECODED:  " + getBase64DecodedCipherText(cText));
        System.out.println("DECODED CIPHER TEXT: " + decodeRawCipherText(null, getBase64DecodedCipherText(cText)));
    } catch (Exception e) {
        e.printStackTrace();

The output looks like:

Here's some code that I ended up writing, based upon @Andrei's answer but without the elegancy/simplicity. The advantage is that it allows a more complex recursive merge and also differs between elements that should be connected with rbind and those that are just connected with c:

# Decided to move this outside the mapply, not sure this is 
# that important for speed but I imagine redefining the function
# might be somewhat time-consuming
mergeLists_internal <- function(o_element, n_element){
  if (is.list(n_element)){
    # Fill in non-existant element with NA elements
    if (length(n_element) != length(o_element)){
      n_unique <- names(n_element)[! names(n_element) %in% names(o_element)]
      if (length(n_unique) > 0){
        for (n in n_unique){
          if (is.matrix(n_element[[n]])){
            o_element[[n]] <- matrix(NA, 
                                     nrow=nrow(n_element[[n]]), 
                                     ncol=ncol(n_element[[n]]))
          }else{
            o_element[[n]] <- rep(NA, 
                                  times=length(n_element[[n]]))
          }
        }
      }

      o_unique <- names(o_element)[! names(o_element) %in% names(n_element)]
      if (length(o_unique) > 0){
        for (n in o_unique){
          if (is.matrix(n_element[[n]])){
            n_element[[n]] <- matrix(NA, 
                                     nrow=nrow(o_element[[n]]), 
                                     ncol=ncol(o_element[[n]]))
          }else{
            n_element[[n]] <- rep(NA, 
                                  times=length(o_element[[n]]))
          }
        }
      }
    }  

    # Now merge the two lists
    return(mergeLists(o_element, 
                      n_element))

  }
  if(length(n_element)>1){
    new_cols <- ifelse(is.matrix(n_element), ncol(n_element), length(n_element))
    old_cols <- ifelse(is.matrix(o_element), ncol(o_element), length(o_element))
    if (new_cols != old_cols)
      stop("Your length doesn't match on the elements,",
           " new element (", new_cols , ") !=",
           " old element (", old_cols , ")")
  }

  return(rbind(o_element, 
               n_element, 
               deparse.level=0))
  return(c(o_element, 
           n_element))
}
mergeLists <- function(old, new){
  if (is.null(old))
    return (new)

  m <- mapply(mergeLists_internal, old, new, SIMPLIFY=FALSE)
  return(m)
}

Here's my example:

v1 <- list("a"=c(1,2), b="test 1", sublist=list(one=20:21, two=21:22))
v2 <- list("a"=c(3,4), b="test 2", sublist=list(one=10:11, two=11:12, three=1:2))
mergeLists(v1, v2)

This results in:

$a
     [,1] [,2]
[1,]    1    2
[2,]    3    4

$b
[1] "test 1" "test 2"

$sublist
$sublist$one
     [,1] [,2]
[1,]   20   21
[2,]   10   11

$sublist$two
     [,1] [,2]
[1,]   21   22
[2,]   11   12

$sublist$three
     [,1] [,2]
[1,]   NA   NA
[2,]    1    2

Yeah, I know - perhaps not the most logical merge but I have a complex parallel loop that I had to generate a more customized .combine function for, and therefore I wrote this monster :-)

app.get('/fruit/:fruitName/:fruitColor', function(req, res) {
    var data = {
        "fruit": {
            "apple": req.params.fruitName,
            "color": req.params.fruitColor
        }
    }; 

    send.json(data);
});

If that doesn't work, try using console.log(req.params) to see what it is giving you.

Just try below script:

Jim     1/03/1999   1/01/2000    306  

1. Plot Start and Duration as a stacked bar chart
2. Set the X-Axis minimum to the desired start date
3. Set the Fill Colour of thestart range to no fill
4. Set the Fill of individual bars to suit

Use str.split():

>>> "42 0".split()  # or .split(" ")
['42', '0']

Note that str.split(" ") is identical in this case, but would behave differently if there were more than one space in a row. As well, .split() splits on all whitespace, not just spaces.

Using map usually looks cleaner than using list comprehensions when you want to convert the items of iterables to built-ins like int, float, str, etc. In Python 2:

>>> map(int, "42 0".split())
[42, 0]

In Python 3, map will return a lazy object. You can get it into a list with list():

>>> map(int, "42 0".split())
<map object at 0x7f92e07f8940>
>>> list(map(int, "42 0".split()))
[42, 0]

add like

<head runat="server">
<script src="Registration.js" type="text/javascript"></script>
</head>

OR can add in code behind.

Page.ClientScript.RegisterClientScriptInclude("Registration", ResolveUrl("~/js/Registration.js"));

Another workaround, not beautiful buy workable.

I have an XML file with an element called "MEMDES" with two attribute as "GRADE" and "SPD" to record the RAM module information. There are lot of dupelicate items in SPD.

So here is the code I use to remove the dupelicated items:

        IEnumerable<XElement> MList =
            from RAMList in PREF.Descendants("MEMDES")
            where (string)RAMList.Attribute("GRADE") == "DDR4"
            select RAMList;

        List<string> sellist = new List<string>();

        foreach (var MEMList in MList)
        {
            sellist.Add((string)MEMList.Attribute("SPD").Value);
        }

        foreach (string slist in sellist.Distinct())
        {
            comboBox1.Items.Add(slist);
        }

You just need to use single quotes:

$ echo "$TEST"
test
$ echo '$TEST'
$TEST

Inside single quotes special characters are not special any more, they are just normal characters.

For accessibility reason, I could not pull it off with multiple type=submit buttons. The only way to work natively with a form with multiple buttons but ONLY one can submit the form when hitting the Enter key is to ensure that only one of them is of type=submit while others are in other type such as type=button. By this way, you can benefit from the better user experience in dealing with a form on a browser in terms of keyboard support.

It indicates that the VS Code file watcher is running out of handles because the workspace is large and contains many files. The max limit of watches has been reacherd, you can viewed the limit by running:

cat /proc/sys/fs/inotify/max_user_watches

run below code resolve this issue:

fs.inotify.max_user_watches=524288

There are a lot of interesting answers here and in similar questions. The only things that I can add from personal experience are:

1. Put your audit table in another database. Ideally, you want separation from the original data. If you need to restore your database, you don't really want to restore the audit trail.

2. Denormalize as much as reasonably possible. You want the table to have as few dependencies as possible to the original data. The audit table should be simple and lightning fast to retrieve data from. No fancy joins or lookups across other tables to get to the data.

It's as simple as the one below, and works like a charm.

My solution perfectly answers your question: How to make JQuery-AJAX request synchronous

Set ajax to synchronous before the ajax call, and then reset it after your ajax call:

$.ajaxSetup({async: false});

$ajax({ajax call....});

$.ajaxSetup({async: true});

In your case it would look like this:

$.ajaxSetup({async: false});

$.ajax({
        type: "POST",
        async: "false",
        url: "checkpass.php",
        data: "password="+password,
        success: function(html) {
            var arr=$.parseJSON(html);
            if(arr == "Successful") {
                return true;
            } else {
                return false;
            }
        }
    });


$.ajaxSetup({async: true});

I hope it helps :)

Yes, Array.map() or $.map() does the same thing.

//array.map:
var ids = this.fruits.map(function(v){
    return v.Id;
});

//jQuery.map:
var ids2 = $.map(this.fruits, function (v){
    return v.Id;
});

console.log(ids, ids2);

http://jsfiddle.net/NsCXJ/1/

Since array.map isn't supported in older browsers, I suggest that you stick with the jQuery method.

If you prefer the other one for some reason you could always add a polyfill for old browser support.

You can always add custom methods to the array prototype as well:

Array.prototype.select = function(expr){
    var arr = this;
    //do custom stuff
    return arr.map(expr); //or $.map(expr);
};

var ids = this.fruits.select(function(v){
    return v.Id;
});

An extended version that uses the function constructor if you pass a string. Something to play around with perhaps:

Array.prototype.select = function(expr){
    var arr = this;

    switch(typeof expr){

        case 'function':
            return $.map(arr, expr);
            break;

        case 'string':

            try{

                var func = new Function(expr.split('.')[0], 
                                       'return ' + expr + ';');
                return $.map(arr, func);

            }catch(e){

                return null;
            }

            break;

        default:
            throw new ReferenceError('expr not defined or not supported');
            break;
    }

};

console.log(fruits.select('x.Id'));

http://jsfiddle.net/aL85j/

Update:

Since this has become such a popular answer, I'm adding similar my where() + firstOrDefault(). These could also be used with the string based function constructor approach (which is the fastest), but here is another approach using an object literal as filter:

Array.prototype.where = function (filter) {

    var collection = this;

    switch(typeof filter) { 

        case 'function': 
            return $.grep(collection, filter); 

        case 'object':
            for(var property in filter) {
              if(!filter.hasOwnProperty(property)) 
                  continue; // ignore inherited properties

              collection = $.grep(collection, function (item) {
                  return item[property] === filter[property];
              });
            }
            return collection.slice(0); // copy the array 
                                      // (in case of empty object filter)

        default: 
            throw new TypeError('func must be either a' +
                'function or an object of properties and values to filter by'); 
    }
};


Array.prototype.firstOrDefault = function(func){
    return this.where(func)[0] || null;
};

Usage:

var persons = [{ name: 'foo', age: 1 }, { name: 'bar', age: 2 }];

// returns an array with one element:
var result1 = persons.where({ age: 1, name: 'foo' });

// returns the first matching item in the array, or null if no match
var result2 = persons.firstOrDefault({ age: 1, name: 'foo' }); 

Here is a jsperf test to compare the function constructor vs object literal speed. If you decide to use the former, keep in mind to quote strings correctly.

My personal preference is to use the object literal based solutions when filtering 1-2 properties, and pass a callback function for more complex filtering.

I'll end this with 2 general tips when adding methods to native object prototypes:

1. Check for occurrence of existing methods before overwriting e.g.:

   if(!Array.prototype.where) { Array.prototype.where = ...

2. If you don't need to support IE8 and below, define the methods using Object.defineProperty to make them non-enumerable. If someone used for..in on an array (which is wrong in the first place) they will iterate enumerable properties as well. Just a heads up.

If all you want is to print from Monday onwards, you can use list's index method to find the position where "Monday" is in the list, and iterate from there as explained in other posts. Using list.index saves you hard-coding the index for "Monday", which is a potential source of error:

days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']
for d in days[days.index('Monday'):] :
   print d

If you're using Linux, there's a possibility of a conflict with Alt + click, which is the default for "moving a window".

You can go to menu Settings → Window Behavior → Window Behavior → Actions tab

Just remove Alt + left (hold) and it will work.

This is the best way, because you don't need to hold two + keys to do such a simple task.

If you go to the graphs/contributors page, you can see a list of all the contributors to the repo and how many lines they've added and removed.

Unless I'm missing something, subtracting the aggregate number of lines deleted from the aggregate number of lines added among all contributors should yield the total number of lines of code in the repo. (EDIT: it turns out I was missing something after all. Take a look at orbitbot's comment for details.)

UPDATE:

This data is also available in GitHub's API. So I wrote a quick script to fetch the data and do the calculation:

'use strict';

async function countGithub(repo) {
    const response = await fetch(`https://api.github.com/repos/${repo}/stats/contributors`)
    const contributors = await response.json();
    const lineCounts = contributors.map(contributor => (
        contributor.weeks.reduce((lineCount, week) => lineCount + week.a - week.d, 0)
    ));
    const lines = lineCounts.reduce((lineTotal, lineCount) => lineTotal + lineCount);
    window.alert(lines);
}

countGithub('jquery/jquery'); // or count anything you like

Just paste it in a Chrome DevTools snippet, change the repo and click run.

Disclaimer (thanks to lovasoa):

Take the results of this method with a grain of salt, because for some repos (sorich87/bootstrap-tour) it results in negative values, which might indicate there's something wrong with the data returned from GitHub's API.

UPDATE:

Looks like this method to calculate total line numbers isn't entirely reliable. Take a look at orbitbot's comment for details.

You should specify column names as below. It's good practice and probably solve your problem

insert into abc.employees (col1,col2) 
select col1,col2 from employees where employee_id=100; 

EDIT:

As you said employees has 112 columns (sic!) try to run below select to compare both tables' columns

select * 
from ALL_TAB_COLUMNS ATC1
left join ALL_TAB_COLUMNS ATC2 on ATC1.COLUMN_NAME = ATC1.COLUMN_NAME 
                               and  ATC1.owner = UPPER('2nd owner')
where ATC1.owner = UPPER('abc')
and ATC2.COLUMN_NAME is null
AND ATC1.TABLE_NAME = 'employees'

and than you should upgrade your tables to have the same structure.

I had the same problem, and it turned out I hadn't installed the library.

You should take a look at the new Spatial data-types that were introduced in SQL Server 2008. They are specifically designed this kind of task and make indexing and querying the data much easier and more efficient.

This is a C# Version. It's based on the idea of sort the array.

public int solution(int[] A)
 {
    // write your code in C# 6.0 with .NET 4.5 (Mono)
    Array.Sort(A);
    var max = A.Max();
    if(max < 0)
        return 1;
    else
        for (int i = 1; i < max; i++)
        {
            if(!A.Contains(i)) {
                return i;
            }
        }
    return max + 1;
}

Note there is a difference between Iterable and Iterator.

If you have an Iterable, then with Java 8 you can use this solution:

Iterable<Element> iterable = createIterable();
List<Element> array = StreamSupport
    .stream(iterable.spliterator(), false)
    .collect(Collectors.toList());

As I know Collectors.toList() creates ArrayList instance.

Actually in my opinion, it also looks good in one line.
For example if you need to return List<Element> from some method:

return StreamSupport.stream(iter.spliterator(), false).collect(Collectors.toList());

How can I set a transparent background on JPEG image?

If you intend to keep the image as a JPEG then you can't. As others have suggested, convert it to PNG and add an alpha channel.

Method overriding is when a child class redefines the same method as a parent class, with the same parameters. For example, the standard Java class java.util.LinkedHashSet extends java.util.HashSet. The method add() is overridden in LinkedHashSet. If you have a variable that is of type HashSet, and you call its add() method, it will call the appropriate implementation of add(), based on whether it is a HashSet or a LinkedHashSet. This is called polymorphism.

Method overloading is defining several methods in the same class, that accept different numbers and types of parameters. In this case, the actual method called is decided at compile-time, based on the number and types of arguments. For instance, the method System.out.println() is overloaded, so that you can pass ints as well as Strings, and it will call a different version of the method.

With "Please select one Item"

@Html.DropDownListFor(model => model.ContentManagement_Send_Section,
  new List<SelectListItem> { new SelectListItem { Value = "0", Text = "Plese Select one Item" } }
    .Concat(db.NameOfPaperSections.Select(x => new SelectListItem { Text = x.NameOfPaperSection, Value = x.PaperSectionID.ToString() })),
  new { @class = "myselect" })

Good luck friends.

The answer comes from the javadoc of ZoneId (emphasis mine) ...

A ZoneId is used to identify the rules used to convert between an Instant and a LocalDateTime. There are two distinct types of ID:

• Fixed offsets - a fully resolved offset from UTC/Greenwich, that uses the same offset for all local date-times
• Geographical regions - an area where a specific set of rules for finding the offset from UTC/Greenwich apply

Most fixed offsets are represented by ZoneOffset. Calling normalized() on any ZoneId will ensure that a fixed offset ID will be represented as a ZoneOffset.

... and from the javadoc of ZoneId#of (emphasis mine):

This method parses the ID producing a ZoneId or ZoneOffset. A ZoneOffset is returned if the ID is 'Z', or starts with '+' or '-'.

The argument id is specified as "UTC", therefore it will return a ZoneId with an offset, which also presented in the string form:

System.out.println(now.withZoneSameInstant(ZoneOffset.UTC));
System.out.println(now.withZoneSameInstant(ZoneId.of("UTC")));

Outputs:

2017-03-10T08:06:28.045Z
2017-03-10T08:06:28.045Z[UTC]

As you use the equals method for comparison, you check for object equivalence. Because of the described difference, the result of the evaluation is false.

When the normalized() method is used as proposed in the documentation, the comparison using equals will return true, as normalized() will return the corresponding ZoneOffset:

Normalizes the time-zone ID, returning a ZoneOffset where possible.

now.withZoneSameInstant(ZoneOffset.UTC)
    .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())); // true

As the documentation states, if you use "Z" or "+0" as input id, of will return the ZoneOffset directly and there is no need to call normalized():

now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("Z"))); //true
now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("+0"))); //true

To check if they store the same date time, you can use the isEqual method instead:

now.withZoneSameInstant(ZoneOffset.UTC)
    .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))); // true

Sample

System.out.println("equals - ZoneId.of(\"UTC\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC"))));
System.out.println("equals - ZoneId.of(\"UTC\").normalized(): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())));
System.out.println("equals - ZoneId.of(\"Z\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("Z"))));
System.out.println("equals - ZoneId.of(\"+0\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("+0"))));
System.out.println("isEqual - ZoneId.of(\"UTC\"): "+ nowZoneOffset
        .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))));

Output:

equals - ZoneId.of("UTC"): false
equals - ZoneId.of("UTC").normalized(): true
equals - ZoneId.of("Z"): true
equals - ZoneId.of("+0"): true
isEqual - ZoneId.of("UTC"): true

The callback is made in a different context. You need to bind to this in order to have access inside the callback:

VK.api('users.get',{fields: 'photo_50'},function(data){
    if(data.response){
        this.setState({ //the error happens here
            FirstName: data.response[0].first_name
        });
        console.info(this.state.FirstName);
    }

}.bind(this));

EDIT: Looks like you have to bind both the init and api calls:

VK.init(function(){
        console.info("API initialisation successful");
        VK.api('users.get',{fields: 'photo_50'},function(data){
            if(data.response){
                this.setState({ //the error happens here
                    FirstName: data.response[0].first_name
                });
                console.info(this.state.FirstName);
            }

        }.bind(this));
    }.bind(this), function(){
    console.info("API initialisation failed");

    }, '5.34');

There is a way to turn the validation back to 2.0 for one page. Just add the below code to your web.config:

<configuration>
    <location path="XX/YY">
        <system.web>
            <httpRuntime requestValidationMode="2.0" />
        </system.web>
    </location>

    ...
    the rest of your configuration
    ...

</configuration>

I looked for a C/C++ API for Google Voice for quite a while and never found anything close (the closest was a C# API). Since I really needed it, I decided to just write one myself:

http://github.com/mastermind202/GoogleVoice

I hope others find it useful. Feedback and suggestions welcome.

I have same problem when I use this code

webview.setWebViewClient(new WebViewClient() {
}

so may be you should remove it in your code
And remember to add 3 modes below for your webview

    webview.getSettings().setJavaScriptEnabled(true);  
    webview.getSettings().setLoadWithOverviewMode(true);
    webview.getSettings().setUseWideViewPort(true);

this fixes size based on screen size

Database clustering is a bit of an ambiguous term, some vendors consider a cluster having two or more servers share the same storage, some others call a cluster a set of replicated servers.

Replication defines the method by which a set of servers remain synchronized without having to share the storage being able to be geographically disperse, there are two main ways of going about it:

• master-master (or multi-master) replication: Any server can update the database. It is usually taken care of by a different module within the database (or a whole different software running on top of them in some cases).

  Downside is that it is very hard to do well, and some systems lose ACID properties when in this mode of replication.

  Upside is that it is flexible and you can support the failure of any server while still having the database updated.

• master-slave replication: There is only a single copy of authoritative data, which is the pushed to the slave servers.

  Downside is that it is less fault tolerant, if the master dies, there are no further changes in the slaves.

  Upside is that it is easier to do than multi-master and it usually preserve ACID properties.

Load balancing is a different concept, it consists distributing the queries sent to those servers so the load is as evenly distributed as possible. It is usually done at the application layer (or with a connection pool). The only direct relation between replication and load balancing is that you need some replication to be able to load balance, else you'd have a single server.

Normally you cant update a page from a servlet. Client (browser) has to request an update. Eiter client loads a whole new page or it requests an update to a part of an existing page. This technique is called Ajax.

Make sure the user has a localhost entry in the users table. That was the problem I was having. EX:

CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';

Empty dictionaries evaluate to False in Python:

>>> dct = {}
>>> bool(dct)
False
>>> not dct
True
>>>

Thus, your isEmpty function is unnecessary. All you need to do is:

def onMessage(self, socket, message):
    if not self.users:
        socket.send("Nobody is online, please use REGISTER command" \
                    " in order to register into the server")
    else:
        socket.send("ONLINE " + ' ' .join(self.users.keys()))

Here is a simple way to implement ls command using c. To run use for example ./xls /tmp

    #include<stdio.h>
    #include <dirent.h>
    void main(int argc,char *argv[])
    {
   DIR *dir;
   struct dirent *dent;
   dir = opendir(argv[1]);   

   if(dir!=NULL)
      {
   while((dent=readdir(dir))!=NULL)
                    {
        if((strcmp(dent->d_name,".")==0 || strcmp(dent->d_name,"..")==0 || (*dent->d_name) == '.' ))
            {
            }
       else
              {
        printf(dent->d_name);
        printf("\n");
              }
                    }
       }
       close(dir);
     }

Assuming you are on 10g, you can also use the MERGE statement. This allows you to insert the row if it doesn't exist and ignore the row if it does exist. People tend to think of MERGE when they want to do an "upsert" (INSERT if the row doesn't exist and UPDATE if the row does exist) but the UPDATE part is optional now so it can also be used here.

It's HTML character references for encoding a character by its decimal code point

Look at the ASCII table here and you'll see that 39 (hex 0x27, octal 47) is the code for apostrophe

Drive letter can be used in the source like

scp /c/path/to/file.txt user@server:/dir1/file.txt

[] extracts a list, [[]] extracts elements within the list

alist <- list(c("a", "b", "c"), c(1,2,3,4), c(8e6, 5.2e9, -9.3e7))

str(alist[[1]])
 chr [1:3] "a" "b" "c"

str(alist[1])
List of 1
 $ : chr [1:3] "a" "b" "c"

str(alist[[1]][1])
 chr "a"

Just loop...

foreach(var table in DataSet1.Tables) {
    foreach(var col in table.Columns) {
       ...
    }
    foreach(var row in table.Rows) {
        object[] values = row.ItemArray;
        ...
    }
}

<form method="get" id="form1" action="something.php">

<!-- External button-->
<button type="submit" form="form1">Click me!</button>

This worked for me, to have a remote submit button for a form.

In my case I have different application.properties depending on the environment, something like:

application.properties (base file)
application-dev.properties
application-qa.properties
application-prod.properties

and application.properties contains a property spring.profiles.active to pick the proper file.

For my integration tests, I created a new application-test.properties file inside test/resources and with the @TestPropertySource({ "/application-test.properties" }) annotation this is the file who is in charge of picking the application.properties I want depending on my needs for those tests

You write this function in sql server after that problem will be solved.

If your classes are in the same package, you won't need to import. To call a method from class B in class A, you should use classB.methodName(arg)

Usually you don't want just an if but an else clause as well.

if(!(str instanceof String)) { /* do Something */ } 
else { /* do something else */ }

can be written as

if(str instanceof String) { /* do Something else */ } 
else { /* do something */ }

Or you can write the code so you don't need to know if its a String or not. e.g.

if(!(str instanceof String)) { str = str.toString(); } 

can be written as

str = str.toString();

If you only have as "click event handler", use a <button> instead. A link has a specific semantic meaning.

E.g.:

<button onclick="ShowOld(2367,146986,2)">
    <img title="next page" alt="next page" src="/themes/me/img/arrn.png">
</button>

The MSVCR100.dll file is part of the Microsoft Visual C++, redistributables. You can install them and see if this solves your problem. After you install the above check if your wamp installation is correctly setup. Search for "my wamp icon stays orange" posts.

UPDATE 2019

Wampserver 3 requires Visual C++ Redistributable for Visual Studio 2012 Update 4 You can download it at: https://www.microsoft.com/en-us/download/details.aspx?id=30679 There you can select the x86 or x64 version depending on your system

This article on the WampServer forums shows all the Microsoft Visual C++ runtime libraries you need to have installed on your system for each version of WampServer. To quote:

For Windows 32 : Be sure that you have installed the Visual C++ 2010 SP1 Redistributable Package x86 : VC10 SP1 vcredist_x86.exe

http://www.microsoft.com/download/en/details.aspx?id=8328

For Windows 64 : Be sure that you have installed the Visual C++ 2010 SP1 Redistributable Package x64 : VC10 SP1 vcredist_x64.exe

http://www.microsoft.com/download/en/details.aspx?id=13523

Apache will not run without this component

In fact if you are running the 64bit Windows it is a good idea to install all the 32bit libraries as well as the 64bit ones. After all 64bit windows runs 64 and 32 bit code. You will probably find you need at least one of the 32bit runtimes for some app/utility you will install at some point.

UPDATE

If you are running WAMPServer 2.5 you also need the VC11 redist. Visual C++ Redistributable for Visual Studio 2012

29.08.2014 with WAMP 2.5 I agree that VC11 is needed and it is not a bad idea to have previous distributions installed. It will be needed by other application. I am not sure if you need bit 32 version

http://www.microsoft.com/en-us/download/confirmation.aspx?id=30679

UPDATE Aug. 3rd 2016

As I was informed by Fred -ii- (many thanks by the way) the link for the post in the wamp forums doesn't work anymore. Since I could not find the original link you can try http://forum.wampserver.com/read.php?2,138295. It has lots of info and may help you.

There's no harm in using the right tool for the job, I find running (from Powershell)

sc.exe \\server delete "MyService" 

the most reliable method that does not have many dependencies.

At the time of writing in 2013, this was one way to do it. Composer has added support for better ways: See @igorw 's answer

DO YOU HAVE A REPOSITORY?

Git, Mercurial and SVN is supported by Composer.

DO YOU HAVE WRITE ACCESS TO THE REPOSITORY?

Yes?

DOES THE REPOSITORY HAVE A composer.json FILE

If you have a repository you can write to: Add a composer.json file, or fix the existing one, and DON'T use the solution below.

Go to @igorw 's answer

ONLY USE THIS IF YOU DON'T HAVE A REPOSITORY
OR IF THE REPOSITORY DOES NOT HAVE A composer.json AND YOU CANNOT ADD IT

This will override everything that Composer may be able to read from the original repository's composer.json, including the dependencies of the package and the autoloading.

Using the package type will transfer the burden of correctly defining everything onto you. The easier way is to have a composer.json file in the repository, and just use it.

This solution really only is for the rare cases where you have an abandoned ZIP download that you cannot alter, or a repository you can only read, but it isn't maintained anymore.

Laravel 5.6 method: https://laravel.com/docs/5.6/views#passing-data-to-views

Example, with sharing a model collection to all views (AppServiceProvider.php):

use Illuminate\Support\Facades\View;
use App\Product;

public function boot()
{
    $products = Product::all();
    View::share('products', $products);

}

Use ThenByDescending:

var hold = MyList.OrderBy(x => x.StartDate)
                 .ThenByDescending(x => x.EndDate)
                 .ToList();

You can also use query syntax and say:

var hold = (from x in MyList
           orderby x.StartDate, x.EndDate descending
           select x).ToList();

ThenByDescending is an extension method on IOrderedEnumerable which is what is returned by OrderBy. See also the related method ThenBy.

Indexing a list is done using double bracket, i.e. hypo_list[[1]] (e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table does not return a table but a dataframe (see value section in ?read.table). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.

Note: In R, the index for the first entry is a 1 (not 0 like in some other languages).

Dataframes

l <- list(anscombe, iris)   # put dfs in list
l[[1]]             # returns anscombe dataframe

anscombe[1:2, 2]   # access first two rows and second column of dataset
[1] 10  8

l[[1]][1:2, 2]     # the same but selecting the dataframe from the list first
[1] 10  8

Table objects

tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2)  # put tables in a list

tbl1[1:2]              # access first two elements of table 1 

Now with the list

l[[1]]                 # access first table from the list

1  2  3  4  5 
9 11 12  9  9 

l[[1]][1:2]            # access first two elements in first table

1  2 
9 11 

Just put the below simple code :

notification.sound = Uri.parse("android.resource://"
        + context.getPackageName() + "/" + R.raw.sound_file);

For Default Sound:

notification.defaults |= Notification.DEFAULT_SOUND;

I got the same error but in PyCharm because I accidentally deleted my VCS origin. After re-adding my origin I ran:

git fetch

which reloaded all of my branches. I then clicked the button to update the project, and I was back to normal.

C# 8.0 is published now so you can make reference types nullable too. For this you have to add

#nullable enable

Feature over your namespace. It is detailed here

For example something like this will work:

#nullable enable
namespace TestCSharpEight
{
  public class Developer
  {
    public string FullName { get; set; }
    public string UserName { get; set; }

    public Developer(string fullName)
    {
        FullName = fullName;
        UserName = null;
    }
}}

Also you can have a look this nice article from John Skeet that explains details.

I find that image mapping works pretty well. If you have any headers or footers that are images make sure that you apply a bgcolor="fill in the blank" because outlook in most cases wont load the image and you will be left with a transparent header. If you at least designate a color that works with the over all feel of the email it will be less of a shock for the user. Never try and use any styling sheets. Or CSS at all! Just avoid it.

Depending if you're copying content from a word or shared google Doc be sure to (command+F) Find all the (') and (") and replace them within your editing software (especially dreemweaver) because they will show up as code and it's just not good.

ALT is your best friend. use the ALT tag to add in text to all your images. Because odds are they are not going to load right. And that ALT text is what gets people to click the (see images) button. Also define your images Width, Height and make the boarder 0 so you dont get weird lines around your image.

Consider editing all images within Photoshop with a 15px boarder on each side (make background transparent and save as a PNG 24) of image. Sometimes the email clients do not read any padding styles that you apply to the images so it avoids any weird formatting!

Also i found the line under links particularly annoying so if you apply < style="text-decoration:none; color:#whatever color you want here!" > it will remove the line and give you the desired look.

There is alot that can really mess with the over all look and feel.

Xcode 8.2.1 • Swift 3.0.2

extension Date {
    var hour: Int { return Calendar.autoupdatingCurrent.component(.hour, from: self) }
}

let date = Date()      // "Mar 16, 2017, 3:43 PM"
let hour = date.hour   // 15

Try using:

xattr -rd com.apple.quarantine directoryname

This takes care of recursively removing the pesky attribute everywhere.

I think the previous answer is the best way to do it here is another simple way. just to print the sorted results.

 String path="/tmp";
 String[] dirListing = null;
 File dir = new File(path);
 dirListing = dir.list();
 Arrays.sort(dirListing);
 System.out.println(Arrays.deepToString(dirListing));

If you're using WPF and the previous answers don't help, you can retrieve the result using:

var result = MessageBox.Show("Message", "caption", MessageBoxButton.YesNo, MessageBoxImage.Question);

if (result == MessageBoxResult.Yes)
{
    // Do something
}

In a nutshell :

-> Git Merge: It will simply merge your local changes and remote changes, and that will create another commit history record

-> Git Rebase: It will put your changes above all new remote changes, and rewrite commit history, so your commit history will be much cleaner than git merge. Rebase is a destructive operation. That means, if you do not apply it correctly, you could lose committed work and/or break the consistency of other developer's repositories.

I didn't want to wrap my *ngFor into another div with *ngIf or use [ngClass], so I created a pipe named show:

show.pipe.ts

export class ShowPipe implements PipeTransform {    
  transform(values: any[], show: boolean): any[] {
    if (!show) {
      return[];
    }
    return values;
  }
}

any.page.html

<table>
  <tr *ngFor="let arr of anyArray | show : ngIfCondition">
    <td>{{arr.label}}</td>
  </tr>
</table>

You can use Ruby's open classes to make your code much more readable. For instance, this:

class String
  def initial
    self[0,1]
  end
end

will allow you to use the initial method on any string. So if you have the following variables:

last_name = "Smith"
first_name = "John"

Then you can get the initials very cleanly and readably:

puts first_name.initial   # prints J
puts last_name.initial    # prints S

The other method mentioned here doesn't work on Ruby 1.8 (not that you should be using 1.8 anymore anyway!--but when this answer was posted it was still quite common):

puts 'Smith'[0]           # prints 83

Of course, if you're not doing it on a regular basis, then defining the method might be overkill, and you could just do it directly:

puts last_name[0,1] 

This is the reusable function to wait for an element present in the DOM using an explicit wait.

public void WaitForElement(IWebElement element, int timeout = 2)
{
    WebDriverWait wait = new WebDriverWait(webDriver, TimeSpan.FromMinutes(timeout));
    wait.IgnoreExceptionTypes(typeof(NoSuchElementException));
    wait.IgnoreExceptionTypes(typeof(StaleElementReferenceException));
    wait.Until<bool>(driver =>
    {
        try
        {
            return element.Displayed;
        }
        catch (Exception)
        {
            return false;
        }
    });
}
