To add on the earlier comments, I would like to say the following :

The setTimeout() function in JavaScript does not pause execution of the script per se, but merely tells the compiler to execute the code sometime in the future.

There isn't a function that can actually pause execution built into JavaScript. However, you can write your own function that does something like an unconditional loop till the time is reached by using the Date() function and adding the time interval you need.

I use this way in work life: "Forget common loops" in this case and use this combination of "setInterval" includes "setTimeOut"s:

    function iAsk(lvl){
        var i=0;
        var intr =setInterval(function(){ // start the loop 
            i++; // increment it
            if(i>lvl){ // check if the end round reached.
                clearInterval(intr);
                return;
            }
            setTimeout(function(){
                $(".imag").prop("src",pPng); // do first bla bla bla after 50 millisecond
            },50);
            setTimeout(function(){
                 // do another bla bla bla after 100 millisecond.
                seq[i-1]=(Math.ceil(Math.random()*4)).toString();
                $("#hh").after('<br>'+i + ' : rand= '+(Math.ceil(Math.random()*4)).toString()+' > '+seq[i-1]);
                $("#d"+seq[i-1]).prop("src",pGif);
                var d =document.getElementById('aud');
                d.play();                   
            },100);
            setTimeout(function(){
                // keep adding bla bla bla till you done :)
                $("#d"+seq[i-1]).prop("src",pPng);
            },900);
        },1000); // loop waiting time must be >= 900 (biggest timeOut for inside actions)
    }

PS: Understand that the real behavior of (setTimeOut): they all will start in same time "the three bla bla bla will start counting down in the same moment" so make a different timeout to arrange the execution.

PS 2: the example for timing loop, but for a reaction loops you can use events, promise async await ..

setTimeout is part of the DOM defined by WHAT WG.

https://html.spec.whatwg.org/multipage/timers-and-user-prompts.html

The method you want is:—

handle = self.setTimeout( handler [, timeout [, arguments... ] ] )

Schedules a timeout to run handler after timeout milliseconds. Any arguments are passed straight through to the handler.

setTimeout(postinsql, 4000, topicId);

Apparently, extra arguments are supported in IE10. Alternatively, you can use setTimeout(postinsql.bind(null, topicId), 4000);, however passing extra arguments is simpler, and that's preferable.

Historical factoid: In days of VBScript, in JScript, setTimeout's third parameter was the language, as a string, defaulting to "JScript" but with the option to use "VBScript". https://docs.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/platform-apis/aa741500(v%3Dvs.85)

Simplest way I could think of: add a class.

Simply add a class (on any element) and check inside the interval if it's there. This is more reliable, customisable and cross-language than any other way, I believe.

var i = 0;_x000D_
this.setInterval(function() {_x000D_
  if(!$('#counter').hasClass('pauseInterval')) { //only run if it hasn't got this class 'pauseInterval'_x000D_
    console.log('Counting...');_x000D_
    $('#counter').html(i++); //just for explaining and showing_x000D_
  } else {_x000D_
    console.log('Stopped counting');_x000D_
  }_x000D_
}, 500);_x000D_
_x000D_
/* In this example, I'm adding a class on mouseover and remove it again on mouseleave. You can of course do pretty much whatever you like */_x000D_
$('#counter').hover(function() { //mouse enter_x000D_
    $(this).addClass('pauseInterval');_x000D_
  },function() { //mouse leave_x000D_
    $(this).removeClass('pauseInterval');_x000D_
  }_x000D_
);_x000D_
_x000D_
/* Other example */_x000D_
$('#pauseInterval').click(function() {_x000D_
  $('#counter').toggleClass('pauseInterval');_x000D_
});

body {_x000D_
  background-color: #eee;_x000D_
  font-family: Calibri, Arial, sans-serif;_x000D_
}_x000D_
#counter {_x000D_
  width: 50%;_x000D_
  background: #ddd;_x000D_
  border: 2px solid #009afd;_x000D_
  border-radius: 5px;_x000D_
  padding: 5px;_x000D_
  text-align: center;_x000D_
  transition: .3s;_x000D_
  margin: 0 auto;_x000D_
}_x000D_
#counter.pauseInterval {_x000D_
  border-color: red;  _x000D_
}

<!-- you'll need jQuery for this. If you really want a vanilla version, ask -->_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
<p id="counter">&nbsp;</p>_x000D_
<button id="pauseInterval">Pause/unpause</button></p>

With the parentheses:

setTimeout("alertMsg()", 3000); // It work, here it treat as a function

Without the quotes and the parentheses:

setTimeout(alertMsg, 3000); // It also work, here it treat as a function

And the third is only using quotes:

setTimeout("alertMsg", 3000); // It not work, here it treat as a string

function alertMsg1() {_x000D_
        alert("message 1");_x000D_
    }_x000D_
    function alertMsg2() {_x000D_
        alert("message 2");_x000D_
    }_x000D_
    function alertMsg3() {_x000D_
        alert("message 3");_x000D_
    }_x000D_
    function alertMsg4() {_x000D_
        alert("message 4");_x000D_
    }_x000D_
_x000D_
    // this work after 2 second_x000D_
    setTimeout(alertMsg1, 2000);_x000D_
_x000D_
    // This work immediately_x000D_
    setTimeout(alertMsg2(), 4000);_x000D_
_x000D_
    // this fail_x000D_
    setTimeout('alertMsg3', 6000);_x000D_
_x000D_
    // this work after 8second_x000D_
    setTimeout('alertMsg4()', 8000);

In the above example first alertMsg2() function call immediately (we give the time out 4S but it don't bother) after that alertMsg1() (A time wait of 2 Second) then alertMsg4() (A time wait of 8 Second) but the alertMsg3() is not working because we place it within the quotes without parties so it is treated as a string.

If you could show the actual page, we, possibly, could help you better.

If you want to trigger the button only after the iframe is loaded, you might want to check if it has been loaded or use the iframe.onload:

<iframe .... onload='buttonWhatever(); '></iframe>


<script type="text/javascript">

    function buttonWhatever() {
        $("#<%=Button1.ClientID%>").click(function (event) {
            $('#<%=TextBox1.ClientID%>').change(function () {
                $('#various3').attr('href', $(this).val());
            });
            $("#<%=Button2.ClientID%>").click();
        });

        function showStickySuccessToast() {
            $().toastmessage('showToast', {
                text: 'Finished Processing!',
                sticky: false,
                position: 'middle-center',
                type: 'success',
                closeText: '',
                close: function () { }
            });
        }
    }

</script>

request.setTimeout(< time in milliseconds >) does the job

https://nodejs.org/api/http.html#http_request_settimeout_timeout_callback

Write a new function for settimeout. Pls try this.

class CowtanApp extends Component {
  constructor(props){
  super(props);
  this.state = {
  timePassed: false
  };
}

componentDidMount() {
  this.setTimeout( () => {
     this.setTimePassed();
  },1000);
}

setTimePassed() {
   this.setState({timePassed: true});
}


render() {

if (!this.state.timePassed){
  return <LoadingPage/>;
}else{
  return (
    <NavigatorIOS
      style = {styles.container}
      initialRoute = {{
        component: LoginPage,
        title: 'Sign In',
      }}/>
  );
}
}
}

I know this is an old question, I'd like to post my approach anyway. This way you don't have to handle the 0 trick that T. J. Crowder expained.

var keepGoing = true;

function myLoop() {
    // ... Do something ...

    if(keepGoing) {
        setTimeout(myLoop, 1000);
    }
}

function startLoop() {
    keepGoing = true;
    myLoop();
}

function stopLoop() {
    keepGoing = false;
}

Here's a setTimeout equivalent, mostly useful when trying to update the User Interface after a delay.

As you may know, updating the user interface can only by done from the UI thread. AsyncTask does that for you by calling its onPostExecute method from that thread.

new AsyncTask<Void, Void, Void>() {
        @Override
        protected Void doInBackground(Void... params) {
            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
            }

            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            // Update the User Interface
        }

    }.execute();

const setTimeoutAsync = (cb, delay) =>
  new Promise((resolve) => {
    setTimeout(() => {
      resolve(cb());
    }, delay);
  });

We can pass custom 'cb fxn' like this one

Not sure if this violates some good practice coding rule but I usually come out with this one:

if(typeof __t == 'undefined')
        __t = 0;
clearTimeout(__t);
__t = setTimeout(callback, 1000);

This prevent the need to declare the timer out of the function.

EDIT: this also don't declare a new variable at each invocation, but always recycle the same.

Hope this helps.

Update 2020

You can await setTimeout with Node.js 15 or above:

const timersPromises = require('timers/promises');

(async () => {
  const result = await timersPromises.setTimeout(2000, 'resolved')
  // Executed after 2 seconds
  console.log(result); // "resolved"
})()

Timers Promises API: https://nodejs.org/api/timers.html#timers_timers_promises_api (library already built in Node)

Note: Stability: 1 - Use of the feature is not recommended in production environments.

Updated 10-second countdown using class Clock extends Component

import React, { Component } from 'react';

class Clock extends Component {
  constructor(props){
    super(props);
    this.state = {currentCount: 10}
  }
  timer() {
    this.setState({
      currentCount: this.state.currentCount - 1
    })
    if(this.state.currentCount < 1) { 
      clearInterval(this.intervalId);
    }
  }
  componentDidMount() {
    this.intervalId = setInterval(this.timer.bind(this), 1000);
  }
  componentWillUnmount(){
    clearInterval(this.intervalId);
  }
  render() {
    return(
      <div>{this.state.currentCount}</div>
    );
  }
}

module.exports = Clock;

If you're using underscore, you can use bind.

E.g.

if (this.options.destroyOnHide) {
     setTimeout(_.bind(this.tip.destroy, this), 1000);
}

This accomplishes the same thing but is much simpler:

$(document).ready(function() {  
   $("#board").delay(1000).append(".");
});

You can chain a delay before almost any jQuery method.

You need to include a jar that this class exists in. You can find it here

If using Maven, you can add the following dependency declaration:

<dependency>
  <groupId>com.google.code.findbugs</groupId>
  <artifactId>jsr305</artifactId>
  <version>3.0.2</version>
</dependency>

and for Gradle:

dependencies {
  testImplementation 'com.google.code.findbugs:jsr305:3.0.2'
}

Another way would be:

string="Paris, France, Europe"
IFS=', ' arr=(${string})

Now your elements are stored in "arr" array. To iterate through the elements:

for i in ${arr[@]}; do echo $i; done

For iterating backwards see this answer.

Iterating forwards is almost identical. Just change the iterators / swap decrement by increment. You should prefer iterators. Some people tell you to use std::size_t as the index variable type. However, that is not portable. Always use the size_type typedef of the container (While you could get away with only a conversion in the forward iterating case, it could actually go wrong all the way in the backward iterating case when using std::size_t, in case std::size_t is wider than what is the typedef of size_type):

Using std::vector

Using iterators

for(std::vector<T>::iterator it = v.begin(); it != v.end(); ++it) {
    /* std::cout << *it; ... */
}

Important is, always use the prefix increment form for iterators whose definitions you don't know. That will ensure your code runs as generic as possible.

Using Range C++11

for(auto const& value: a) {
     /* std::cout << value; ... */

Using indices

for(std::vector<int>::size_type i = 0; i != v.size(); i++) {
    /* std::cout << v[i]; ... */
}

Using arrays

Using iterators

for(element_type* it = a; it != (a + (sizeof a / sizeof *a)); it++) {
    /* std::cout << *it; ... */
}

Using Range C++11

for(auto const& value: a) {
     /* std::cout << value; ... */

Using indices

for(std::size_t i = 0; i != (sizeof a / sizeof *a); i++) {
    /* std::cout << a[i]; ... */
}

Read in the backward iterating answer what problem the sizeof approach can yield to, though.

Consider explicitly setting the header in the $http.post (I put application/json, as I am not sure which of the two versions in your example is the working one, but you can use application/x-www-form-urlencoded if it's the other one):

$http.post("/customer/data/autocomplete", {term: searchString}, {headers: {'Content-Type': 'application/json'} })
        .then(function (response) {
            return response;
        });

this is Postgres UPDATE JOIN format:

UPDATE address 
SET cid = customers.id
FROM customers 
WHERE customers.id = address.id

Here's the other variations: http://mssql-to-postgresql.blogspot.com/2007/12/updates-in-postgresql-ms-sql-mysql.html

Either return a value from your main or use the exit function. Both take an int. It doesn't really matter what value you return unless you have an external process watching for the return value.

Just add this one-line class in your CSS, and use the bootstrap label component.

.label-as-badge {
    border-radius: 1em;
}

Compare this label and badge side by side:

<span class="label label-default label-as-badge">hello</span>
<span class="badge">world</span>

They appear the same. But in the CSS, label uses em so it scales nicely, and it still has all the "-color" classes. So the label will scale to bigger font sizes better, and can be colored with label-success, label-warning, etc. Here are two examples:

<span class="label label-success label-as-badge">Yay! Rah!</span>

Or where things are bigger:

<div style="font-size: 36px"><!-- pretend an enclosing class has big font size -->
    <span class="label label-success label-as-badge">Yay! Rah!</span>
</div>

11/16/2015: Looking at how we'll do this in Bootstrap 4

Looks like .badge classes are completely gone. But there's a built-in .label-pill class (here) that looks like what we want.

.label-pill {
  padding-right: .6em;
  padding-left: .6em;
  border-radius: 10rem;
}

In use it looks like this:

<span class="label label-pill label-default">Default</span>
<span class="label label-pill label-primary">Primary</span>
<span class="label label-pill label-success">Success</span>
<span class="label label-pill label-info">Info</span>
<span class="label label-pill label-warning">Warning</span>
<span class="label label-pill label-danger">Danger</span>

11/04/2014: Here's an update on why cross-pollinating alert classes with .badge is not so great. I think this picture sums it up:

Those alert classes were not designed to go with badges. It renders them with a "hint" of the intended colors, but in the end consistency is thrown out the window and readability is questionable. Those alert-hacked badges are not visually cohesive.

The .label-as-badge solution is only extending the bootstrap design. We are keeping intact all the decision making made by the bootstrap designers, namely the consideration they gave for readability and cohesion across all the possible colors, as well as the color choices themselves. The .label-as-badge class only adds rounded corners, and nothing else. There are no color definitions introduced. Thus, a single line of CSS.

Yep, it is easier to just hack away and drop in those .alert-xxxxx classes -- you don't have to add any lines of CSS. Or you could care more about the little things and add one line.

@jim mcnamara: try using parentheses for around NF, i. e. $(NF-1) and $(NF) instead of $NF-1 and $NF (works on Mac OS X 10.6.8 for FreeBSD awkand gawk).

echo '
1 2
2 3
one
one two three
' | gawk '{if (NF >= 2) print $(NF-1), $(NF);}'

# output:
# 1 2
# 2 3
# two three

I would suggest you use CryptoJS in this case.

Basically CryptoJS is a growing collection of standard and secure cryptographic algorithms implemented in JavaScript using best practices and patterns. They are fast, and they have a consistent and simple interface.

So if you want to calculate the MD5 hash of your password string then do as follows:

<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/core.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/md5.js"></script>
<script>
    var passhash = CryptoJS.MD5(password).toString();

    $.post(
      'includes/login.php', 
      { user: username, pass: passhash },
      onLogin, 
      'json' );
</script>

So this script will post the hash of your password string to the server.

For further info and support on other hash calculating algorithms you can visit:

http://code.google.com/p/crypto-js/

Sometimes you want to delete a file whatever the case(whatever the exception occurs ,please do delete the file). For such situations.

public static void DeleteFile(string path)
        {
            if (!File.Exists(path))
            {
                return;
            }

            bool isDeleted = false;
            while (!isDeleted)
            {
                try
                {
                    File.Delete(path);
                    isDeleted = true;
                }
                catch (Exception e)
                {
                }
                Thread.Sleep(50);
            }
        }

Note:An exception is not thrown if the specified file does not exist.

I'm not exactly sure how cordova works, but once the licenses are accepted it creates a file. You could create that file manually. It is described on this question, but here's the commands to create the required license file.

Linux:

mkdir "$ANDROID_HOME/licenses"
echo -e "\n8933bad161af4178b1185d1a37fbf41ea5269c55" > "$ANDROID_HOME/licenses/android-sdk-license"

Windows:

mkdir "%ANDROID_HOME%\licenses"
echo |set /p="8933bad161af4178b1185d1a37fbf41ea5269c55" > "%ANDROID_HOME%\licenses\android-sdk-license"

To prevent the extra float decimal (i.e. 50.85 - 50 give 0.850000000852), in my case I just need 2 decimals for money cents.

$n = 50.85;
$whole = intval($n);
$fraction = $n * 100 % 100;

The default value is set with andoid:rating in the xml layout.

Submit form when your checkbox is checked

$(document).ready(function () {   
$("#yoursubmitbuttonid").click(function(){           
                if( $(".yourcheckboxclass").is(":checked") )
                {
                    $("#yourformId").submit();

                }else{
                    alert("Please select !!!");
                    return false;
                }
                return false;
            }); 
});

FileInfo.Length will return the length of file, in bytes (not size on disk), so this is what you are looking for, I think.

You can use quotemeta (\Q \E) if your Perl is version 5.16 or later, but if below you can simply avoid using a regular expression at all.

For example, by using the index command:

if (index($text_to_search, $search_string) > -1) {
    print "wee";
}

<a href="javascript:alert('Hello!');">Clicky</a>

EDIT, years later: NO! Don't ever do this! I was young and stupid!

Edit, again: A couple people have asked why you shouldn't do this. There's a couple reasons:

1. Presentation: HTML should focus on presentation. Putting JS in an HREF means that your HTML is now, kinda, dealing with business logic.

2. Security: Javascript in your HTML like that violates Content Security Policy (CSP). Content Security Policy (CSP) is an added layer of security that helps to detect and mitigate certain types of attacks, including Cross-Site Scripting (XSS) and data injection attacks. These attacks are used for everything from data theft to site defacement or distribution of malware. Read more here.

3. Accessibility: Anchor tags are for linking to other documents/pages/resources. If your link doesn't go anywhere, it should be a button. This makes it a lot easier for screen readers, braille terminals, etc, to determine what's going on, and give visually impaired users useful information.

You can use:

str.replace(/text/g, "replaced text");

On my mac I had to remove the cache directory ~/Library/Caches/pip/

Separate with commas:

http://localhost:8080/MovieDB/GetJson?name=Actor1,Actor2,Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name=Actor1&name=Actor2&name=Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name[0]=Actor1&name[1]=Actor2&name[2]=Actor3&startDate=20120101&endDate=20120505

Either way, your method signature needs to be:

@RequestMapping(value = "/GetJson", method = RequestMethod.GET) 
public void getJson(@RequestParam("name") String[] ticker, @RequestParam("startDate") String startDate, @RequestParam("endDate") String endDate) {
   //code to get results from db for those params.
 }

Here is the "native" text tools way:

#!/bin/bash

string="abcd"
first=`echo $string|cut -c1|tr [a-z] [A-Z]`
second=`echo $string|cut -c2-`
echo $first$second

The permament pool contains everything that is not your application data, but rather things required for the VM: typically it contains interned strings, the byte code of defined classes, but also other "not yours" pieces of data.

I think the short answer is no. For a more generic case in n dimensions, I came up with this:

# For 2-dimensional data, 4 values
a = np.array([[0, 1, 2], [3, 2, 1]])
z = np.zeros(list(a.shape) + [4])
z[list(np.indices(z.shape[:-1])) + [a]] = 1

I am wondering if there is a better solution -- I don't like that I have to create those lists in the last two lines. Anyway, I did some measurements with timeit and it seems that the numpy-based (indices/arange) and the iterative versions perform about the same.

I had to select from the information schema to get details of my tables and columns; in case it helps anyone:

SELECT * FROM information_schema.tables
WHERE table_schema = 'myschema'; 

SELECT * FROM information_schema.columns
WHERE table_schema = 'myschema' AND table_name = 'mytable'; 

Python 2

What you're looking for is urllib.quote_plus:

>>> urllib.quote_plus('string_of_characters_like_these:$#@=?%^Q^$')
'string_of_characters_like_these%3A%24%23%40%3D%3F%25%5EQ%5E%24'

Python 3

In Python 3, the urllib package has been broken into smaller components. You'll use urllib.parse.quote_plus (note the parse child module)

import urllib.parse
urllib.parse.quote_plus(...)

You can create you own conditional compile-time symbols (any name you like). Go to the "project Build dialog", located in the project properties box, menu option: Project->[projectname] Properties...

You can also define them "at the top of the C# code file". Like:

#define RELEASE
// or
#undef RELEASE

you can use the symbol in a #if statement:

#if RELEASE
// code ...
#elif …
// code ...
#endif

// or

#if !RELEASE
// code ...
#endif

It seems that this is a very long running problem, with a lot of differing explanations. I took the advice of the two most common presented answers here, but neither one of these solved my problems of the VM claiming it couldn't afford the bytes to perform the decoding part of the process. After some digging I learned that the real problem here is the decoding process taking away from the NATIVE heap.

See here: BitmapFactory OOM driving me nuts

That lead me to another discussion thread where I found a couple more solutions to this problem. One is to callSystem.gc(); manually after your image is displayed. But that actually makes your app use MORE memory, in an effort to reduce the native heap. The better solution as of the release of 2.0 (Donut) is to use the BitmapFactory option "inPurgeable". So I simply added o2.inPurgeable=true; just after o2.inSampleSize=scale;.

More on that topic here: Is the limit of memory heap only 6M?

Now, having said all of this, I am a complete dunce with Java and Android too. So if you think this is a terrible way to solve this problem, you are probably right. ;-) But this has worked wonders for me, and I have found it impossible to run the VM out of heap cache now. The only drawback I can find is that you are trashing your cached drawn image. Which means if you go RIGHT back to that image, you are redrawing it each and every time. In the case of how my application works, that is not really a problem. Your mileage may vary.

If I use exit() in a code and run it in the shell, it shows a message asking whether I want to kill the program or not. It's really disturbing. See here

But sys.exit() is better in this case. It closes the program and doesn't create any dialogue box.

open f, "test.txt"
$file = join '', <f>

<f> - returns an array of lines from our file (if $/ has the default value "\n") and then join '' will stick this array into.

git branch --set-upstream-to=origin/main

$('#myDiv').children().each( (index, element) => {
    console.log(index);     // children's index
    console.log(element);   // children's element
 });

This iterates through all the children and their element with index value can be accessed separately using element and index respectively.

It depends on your requirements. Choosing a pivot at random makes it harder to create a data set that generates O(N^2) performance. 'Median-of-three' (first, last, middle) is also a way of avoiding problems. Beware of relative performance of comparisons, though; if your comparisons are costly, then Mo3 does more comparisons than choosing (a single pivot value) at random. Database records can be costly to compare.

Update: Pulling comments into answer.

mdkess asserted:

'Median of 3' is NOT first last middle. Choose three random indexes, and take the middle value of this. The whole point is to make sure that your choice of pivots is not deterministic - if it is, worst case data can be quite easily generated.

To which I responded:

• Analysis Of Hoare's Find Algorithm With Median-Of-Three Partition (1997) by P Kirschenhofer, H Prodinger, C Martínez supports your contention (that 'median-of-three' is three random items).

• There's an article described at portal.acm.org that is about 'The Worst Case Permutation for Median-of-Three Quicksort' by Hannu Erkiö, published in The Computer Journal, Vol 27, No 3, 1984. [Update 2012-02-26: Got the text for the article. Section 2 'The Algorithm' begins: 'By using the median of the first, middle and last elements of A[L:R], efficient partitions into parts of fairly equal sizes can be achieved in most practical situations.' Thus, it is discussing the first-middle-last Mo3 approach.]

• Another short article that is interesting is by M. D. McIlroy, "A Killer Adversary for Quicksort", published in Software-Practice and Experience, Vol. 29(0), 1–4 (0 1999). It explains how to make almost any Quicksort behave quadratically.

• AT&T Bell Labs Tech Journal, Oct 1984 "Theory and Practice in the Construction of a Working Sort Routine" states "Hoare suggested partitioning around the median of several randomly selected lines. Sedgewick [...] recommended choosing the median of the first [...] last [...] and middle". This indicates that both techniques for 'median-of-three' are known in the literature. (Update 2014-11-23: The article appears to be available at IEEE Xplore or from Wiley — if you have membership or are prepared to pay a fee.)

• 'Engineering a Sort Function' by J L Bentley and M D McIlroy, published in Software Practice and Experience, Vol 23(11), November 1993, goes into an extensive discussion of the issues, and they chose an adaptive partitioning algorithm based in part on the size of the data set. There is a lot of discussion of trade-offs for various approaches.

• A Google search for 'median-of-three' works pretty well for further tracking.

Thanks for the information; I had only encountered the deterministic 'median-of-three' before.

The above answers work fine too, but I've found you can usually just use message.author.send("blah blah") instead of message.author.sendMessage("blah blah").

-EDIT- : This is because the sendMessage command is outdated as of v12 in Discord Js

.send tends to work better for me in general than .sendMessage, which sometimes runs into problems. Hope that helps a teeny bit!

You can use this code:

var vid = document.getElementById("video1");

function slowPlaySpeed() { 
    vid.playbackRate = 0.5;
} 

function normalPlaySpeed() { 
    vid.playbackRate = 1;
} 

function fastPlaySpeed() { 
    vid.playbackRate = 2;
}

ObjectPath is simple and ligthweigth query language for JSON documents of complex or unknown structure. It's similar to XPath or JSONPath, but much more powerful thanks to embedded arithmetic calculations, comparison mechanisms and built-in functions.

Python version is mature and used in production. JS is still in beta.

Probably in the near future we will provide a full-fledged Javascript version. We also want to develop it further, so that it could serve as a simpler alternative to Mongo queries.

Actually, I had this problem same as you. My windows is server 2008 and my subversion info is :

TortoiseSVN 1.7.6, Build 22632 - 64 Bit , 2012/03/08 18:29:39 Subversion 1.7.4, apr 1.4.5 apr-utils 1.3.12 neon 0.29.6 OpenSSL 1.0.0g 18 Jan 2012 zlib 1.2.5

I used this way and I solved this problem. I used [group] option. this option makes problem. I rewrite authz file contents. I remove group option. and I set one by one. I use well.

Thanks for reading.

I do like this,you can have a try

public String getIpAddr(HttpServletRequest request) {      
   String ip = request.getHeader("x-forwarded-for");      
   if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {      
       ip = request.getHeader("Proxy-Client-IP");      
   }      
   if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {      
       ip = request.getHeader("WL-Proxy-Client-IP");      
   }      
   if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {      
       ip = request.getRemoteAddr();      
   }      
   return ip;      
}   

//manifest file outside the application tag
//please give permission write this 
//<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
        File file = new File("/mnt");
        String[] fileNameList = file.list(); //file names list inside the mnr folder
        String all_names = ""; //for the log information
        String foundedFullNameOfExtCard = ""; // full name of ext card will come here
        boolean isExtCardFounded = false;
        for (String name : fileNameList) {
            if (!isExtCardFounded) {
                isExtCardFounded = name.contains("ext");
                foundedFullNameOfExtCard = name;
            }
            all_names += name + "\n"; // for log
        }
        Log.d("dialog", all_names + foundedFullNameOfExtCard);

If you have a special character in the column names, either select or select_may not work as expected. This property of dplyr of using ".". To refer to the data set in the question, the following line can be used to solve this problem:

drop.cols <- c('Sepal.Length', 'Sepal.Width')
  iris %>% .[,setdiff(names(.),drop.cols)]

You can, but you should not https://web.archive.org/web/20151009224806/http://docs.mongodb.org/manual/tutorial/create-an-auto-incrementing-field/

Each object in mongo already has an id, and they are sortable in insertion order. What is wrong with getting collection of user objects, iterating over it and use this as incremented ID? Er go for kind of map-reduce job entirely

In Excel 2003 you should be able to create a formatting rule like:

=A1<>"" and then drag/copy this to other cells as needed.

If that doesn't work, try =Len(A1)>0.

If there may be spaces in the cell which you will consider blank, then do:

=Len(Trim(A1))>0

Let me know if you can't get any of these to work. I have an old machine running XP and Office 2003, I can fire it up to troubleshoot if needed.

You should specify the db you are connecting to:

jdbc:mysql://localhost:3306/mydb

You can use the following attributes for webkit, which reach into the shadow DOM:

::-webkit-scrollbar              { /* 1 */ }
::-webkit-scrollbar-button       { /* 2 */ }
::-webkit-scrollbar-track        { /* 3 */ }
::-webkit-scrollbar-track-piece  { /* 4 */ }
::-webkit-scrollbar-thumb        { /* 5 */ }
::-webkit-scrollbar-corner       { /* 6 */ }
::-webkit-resizer                { /* 7 */ }

Here's a working fiddle with a red scrollbar, based on code from this page explaining the issues.

Using this and your solution, you can handle all browsers except Firefox, which at this point I think still requires a javascript solution.

This may have been answered before: Python URLLib / URLLib2 POST.

Your server is likely performing a 302 redirect from http://myserver/post_service to http://myserver/post_service/. When the 302 redirect is performed, the request changes from POST to GET (see Issue 1401). Try changing url to http://myserver/post_service/.

defaultMember already is an alias - it doesn't need to be the name of the exported function/thing. Just do

import alias from 'my-module';

Alternatively you can do

import {default as alias} from 'my-module';

but that's rather esoteric.

Siddharth's answer is nice, but relies on globally-scoped variables. There's a better, more OOP-friendly way.

A UserForm is a class module like any other - the only difference is that it has a hidden VB_PredeclaredId attribute set to True, which makes VB create a global-scope object variable named after the class - that's how you can write UserForm1.Show without creating a new instance of the class.

Step away from this, and treat your form as an object instead - expose Property Get members and abstract away the form's controls - the calling code doesn't care about controls anyway:

Option Explicit
Private cancelling As Boolean

Public Property Get UserId() As String
    UserId = txtUserId.Text
End Property

Public Property Get Password() As String
    Password = txtPassword.Text
End Property

Public Property Get IsCancelled() As Boolean
    IsCancelled = cancelling
End Property

Private Sub OkButton_Click()
    Me.Hide
End Sub

Private Sub CancelButton_Click()
    cancelling = True
    Me.Hide
End Sub

Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
    If CloseMode = VbQueryClose.vbFormControlMenu Then
        cancelling = True
        Cancel = True
        Me.Hide
    End If
End Sub

Now the calling code can do this (assuming the UserForm was named LoginPrompt):

With New LoginPrompt
    .Show vbModal
    If .IsCancelled Then Exit Sub
    DoSomething .UserId, .Password
End With

Where DoSomething would be some procedure that requires the two string parameters:

Private Sub DoSomething(ByVal uid As String, ByVal pwd As String)
    'work with the parameter values, regardless of where they came from
End Sub

I was facing the same issue. I was missing DriverManager.registerDriver() call, before getting the connection using the connection URL and user credentials.

It got fixed on Linux as below:

DriverManager.registerDriver(new org.apache.derby.jdbc.ClientDriver());
connection = DriverManager.getConnection("jdbc:derby://localhost:1527//tmp/Test/DB_Name", user, pass);

For Windows:

DriverManager.registerDriver(new org.apache.derby.jdbc.ClientDriver());
connection = DriverManager.getConnection("jdbc:derby://localhost:1527/C:/Users/Test/DB_Name", user, pass);

You should add this:

android:focusableInTouchMode="true"

On a x64 system, system32 is for 64 bit and syswow64 is for 32 bit (not the other way around as stated in another answer). WOW (Windows on Windows) is the 32 bit subsystem that runs under the 64 bit subsystem).

It's a mess in naming terms, and serves only to confuse, but that's the way it is.

Again ...

syswow64 is 32 bit, NOT 64 bit.

system32 is 64 bit, NOT 32 bit.

There is a regsrv32 in each of these directories. One is 64 bit, and the other is 32 bit. It is the same deal with odbcad32 and et al. (If you want to see 32-bit ODBC drivers which won't show up with the default odbcad32 in system32 which is 64-bit.)

In a Firebird database the AFTER myOtherColumn does not work but you can try re-positioning the column using:

ALTER TABLE name ALTER column POSITION new_position

I guess it may work in other cases as well.

Restarting Visual Studio actually fixed it for me. I'm thinking it was caused by old assembly files still in use, and performing a "Clean Build" or restarting VS should fix it.

You can capture all output in one variable, but the lines will be separated by a character of your choice (# in the example below) instead of an actual CR-LF.

@echo off
setlocal EnableDelayedExpansion
for /f "delims=" %%i in ('dir /b') do (
    if "!DIR!"=="" (set DIR=%%i) else (set DIR=!DIR!#%%i)
)
echo directory contains:
echo %DIR%

Second version, if you need to print the contents out line-by-line. This takes advanted of the fact that there won't be duplicate lines of output from "dir /b", so it may not work in the general case.

@echo off
setlocal EnableDelayedExpansion
set count=0
for /f "delims=" %%i in ('dir /b') do (
    if "!DIR!"=="" (set DIR=%%i) else (set DIR=!DIR!#%%i)
    set /a count = !count! + 1
)

echo directory contains:
echo %DIR%

for /l %%c in (1,1,%count%) do (
    for /f "delims=#" %%i in ("!DIR!") do (
        echo %%i
        set DIR=!DIR:%%i=!
    )
)

My problem was slightly different.

By default Eclipse saved my manifest.json as an ANSI encoded text file.

Solution:

• Open in Notepad
• File -> Save As
• select UTF-8 from the encoding drop-down in the bottom left.
• Save

There are multiple ways of doing that you can use either place or grid or even the packmethod.

Sample code:

from tkinter import *
root = Tk()

l = Label(root, text="hello" )
l.pack(padx=6, pady=4) # where padx and pady represent the x and y axis respectively
# well you can also use side=LEFT inside the pack method of the label widget.

To place a widget to on basis of columns and rows , use the grid method:

but = Button(root, text="hello" )
but.grid(row=0, column=1)

In addition to other answers which helped me, you can also add to surrounding div. In my case this was for sign on with user Name/Password fields.

<div (keyup.enter)="login()" class="container-fluid">

If you use Custom Actions written in .NET as part of your MSI installer then you have another problem.

The 'shim' that runs these custom actions is always 32bit then your custom action will run 32bit as well, despite what target you specify.

More info & some ninja moves to get around (basically change the MSI to use the 64 bit version of this shim)

Since you are using jQuery. How about the jQuery.extend() method?

http://api.jquery.com/jQuery.extend/

Description: Merge the contents of two or more objects together into the first object.

To calculate the mean, loop through the list/array of numbers, keeping track of the partial sums and the length. Then return the sum/length.

double sum = 0.0;
int length = 0;

for( double number : numbers ) {
    sum += number;
    length++;
}

return sum/length;

Variance is calculated similarly. Standard deviation is simply the square root of the variance:

double stddev = Math.sqrt( variance );

import json
data = json.dumps(list)
print(data)

The above code snippet should work.

If you add JDK_PATH in gradle.properties your build become dependent on on that particular path. Instead Run gradle task with following command line parametemer

gradle build -Dorg.gradle.java.home=/JDK_PATH

This way your build is not dependent on some concrete path.

as simple as:

tmpHM.each{ key, value -> 
  doSomethingWithKeyAndValue key, value
}

My solution, only need to call this method.

public static void dropColumn(SQLiteDatabase db, String tableName, String[] columnsToRemove) throws java.sql.SQLException {
    List<String> updatedTableColumns = getTableColumns(db, tableName);
    updatedTableColumns.removeAll(Arrays.asList(columnsToRemove));
    String columnsSeperated = TextUtils.join(",", updatedTableColumns);

    db.execSQL("ALTER TABLE " + tableName + " RENAME TO " + tableName + "_old;");
    db.execSQL("CREATE TABLE " + tableName + " (" + columnsSeperated + ");");
    db.execSQL("INSERT INTO " + tableName + "(" + columnsSeperated + ") SELECT "
            + columnsSeperated + " FROM " + tableName + "_old;");
    db.execSQL("DROP TABLE " + tableName + "_old;");
}

And auxiliary method to get the columns:

public static List<String> getTableColumns(SQLiteDatabase db, String tableName) {
    ArrayList<String> columns = new ArrayList<>();
    String cmd = "pragma table_info(" + tableName + ");";
    Cursor cur = db.rawQuery(cmd, null);

    while (cur.moveToNext()) {
        columns.add(cur.getString(cur.getColumnIndex("name")));
    }
    cur.close();

    return columns;
}

Do you mean something like this:

HTML

<div class="row">
  <div class="container">

    <div class="col-md-4">
      left content
    </div>

    <div class="col-md-4 col-md-offset-4">

      <div class="yellow-background">
        text
        <div class="pull-right">right content</div>  
      </div>

    </div>
  </div>
</div>

CSS

.yellow-background {
  background: blue;
}

.pull-right {
  background: yellow;
}

A full example can be found on Codepen.

It is not possible prolly cuz it would be so easy to XSS. Also , current HTML sanitizers that are available don't disallow content property.

(Definitely not the greatest answer here but I just wanted to share an insight other than the "according to spec... ")

sigma = sum(y*(x - mean)**2)

should be

sigma = np.sqrt(sum(y*(x - mean)**2))

What you are looking for is an AMD compliant loader (like require.js).

http://requirejs.org/

http://requirejs.org/docs/whyamd.html

There are many good open source ones if you look it up. Basically this allows you to define a module of code, and if it is dependent on other modules of code, it will wait until those modules have finished downloading before proceeding to run. This way you can load 10 modules asynchronously and there should be no problems even if one depends on a few of the others to run.

Now days I believe it's preferred to use a function form of typeof() so...

if(filename === undefined || typeof(filename) !== "string" || filename === "") {
   console.log("no filename aborted.");
   return;
}

$this is a special variable and it refers to the same object ie. itself.

it actually refer instance of current class

here is an example which will clear the above statement

<?php
 class Books {
  /* Member variables */
  var $price;
  var $title;

  /* Member functions */
  function setPrice($par){
     $this->price = $par;
  }

  function getPrice(){
     echo $this->price ."<br/>";
  }

  function setTitle($par){
     $this->title = $par;
  }

  function getTitle(){
     echo $this->title ." <br/>";
  }
}
?> 

There is jq for parsing json on the command line:

 jq '.Body'

Visit this for jq: https://stedolan.github.io/jq/

This should get you started:

set datafile separator ","
plot 'infile' using 0:1

an option that worked for me, define the field in the original form as:

forms.CharField(widget = forms.HiddenInput(), required = False)

then when you override it in the new Class it will keep it's place.

import ReactDOM from 'react-dom' ;

class SomeComponent {

  constructor(props) {
    // First, add this to your constructor
    this.handleClickOutside = this.handleClickOutside.bind(this);
  }

  componentWillMount() {
    document.addEventListener('mousedown', this.handleClickOutside, false); 
  }

  // Unbind event on unmount to prevent leaks
  componentWillUnmount() {
    window.removeEventListener('mousedown', this.handleClickOutside, false);
  }

  handleClickOutside(event) {
    if(!ReactDOM.findDOMNode(this).contains(event.path[0])){
       console.log("OUTSIDE");
    }
  }
}

I'd strongly suggest moving away from inline JavaScript, to something like the following:

function redirect(goto){
    var conf = confirm("Are you sure you want to go elswhere?");
    if (conf && goto != '') {
        window.location = goto;
    }
}

var selectEl = document.getElementById('redirectSelect');

selectEl.onchange = function(){
    var goto = this.value;
    redirect(goto);

};

JS Fiddle demo (404 linkrot victim).
JS Fiddle demo via Wayback Machine.
Forked JS Fiddle for current users.

In the mark-up in the JS Fiddle the first option has no value assigned, so clicking it shouldn't trigger the function to do anything, and since it's the default value clicking the select and then selecting that first default option won't trigger the change event anyway.

Update:
The latest example's (2017-08-09) redirect URLs required swapping out due to errors regarding mixed content between JS Fiddle and both domains, as well as both domains requiring 'sameorigin' for framed content. - Albert

I think there is no out-of-the-box support for that in VS Code.

You can install a plugin to give you similar functionality. Eg.:

https://marketplace.visualstudio.com/items?itemName=micnil.vscode-checkpoints

Or the more famous:

https://marketplace.visualstudio.com/items?itemName=xyz.local-history

Some details may need to be configured: The VS Code search gets confused sometimes because of additional folders created by this type of plugins. You can configure it to ignore such folders or change their locations (adding such folders to your .gitignore file also solves this problem).

There is another option that just entails using scikit-learn. As scikit's wiki describes, you can just use the following instructions:

from sklearn.model_selection import train_test_split

data, labels = np.arange(10).reshape((5, 2)), range(5)

data_train, data_test, labels_train, labels_test = train_test_split(data, labels, test_size=0.20, random_state=42)

This way you can keep in sync the labels for the data you're trying to split into training and test.

Try this:

function funcName() {
    alert("test");
}

var run = setInterval(funcName, 10000)

Sql server unlike oracle does not need commits unless you are using transactions.
Immediatly after your update statement the table will be commited, don't use the commit command in this scenario.

That error message also appeared into my VM. First of all, I tried to disable the option "Enable VT-x/AMD-V" (you can find it opening the settings of your VM: Settings->System->Acceleration), there was a warning saying that "Invalid settings detected (you accept the changes and the box was selected again).

Then I read this posts and I tried to enable the Virtualiation Techniuqe (used when you want to enable various VM in your computer (by default is set as Disabled because you don't need that property working.

If it matters whether the file you're looking for is a directory and not just a file, you could use File.directory? or Dir.exist?. This will return true only if the file exists and is a directory.

As an aside, a more idiomatic way to write the method would be to take advantage of the fact that Ruby automatically returns the result of the last expression inside the method. Thus, you could write it like this:

def directory_exists?(directory)
  File.directory?(directory)
end

Note that using a method is not necessary in the present case.

I think the only way to do this is to run another machine in parallel and use that machine to issue commands to your android box similar to how you would with a phone. If you have issues with the IP changing you can reserve an ip on your router and have the machine grab that one instead of asking the routers DHCP for one. This way you can ping the machine and figure out if it's done rebooting to continue the script.

To move up, remove and then add.

To remove - ArrayList.remove and assign the returned object to a variable
Then add this object back at the required index -ArrayList.add(int index, E element)

http://download.oracle.com/javase/6/docs/api/java/util/ArrayList.html#add(int, E)

Along with all above answer i would like to add this point too.

For primitive types,we have fixed memory size i.e for int we have 4 bytes and char we have 2 bytes. And null is used only for objects because there memory size is not fixed.

So by default we have,

   int a=0;

and not

   int a=null;

Same with other primitive types and hence null is only used for objects and not for primitive types.

Just thought i'd share this with anyone who needs more clarity on how to achieve this:

myCanvas is a Canvas control and Parent to all other controllers. This code works to neatly resize to any resolution from 1366 x 768 upward. Tested up to 4k resolution 4096 x 2160

You can use python-docx2txt which is adapted from python-docx but can also extract text from links, headers and footers. It can also extract images.

You can see that your locks are pretty much working as you are using them, if you slow down the process and make them block a bit more. You had the right idea, where you surround critical pieces of code with the lock. Here is a small adjustment to your example to show you how each waits on the other to release the lock.

import threading
import time
import inspect

class Thread(threading.Thread):
    def __init__(self, t, *args):
        threading.Thread.__init__(self, target=t, args=args)
        self.start()

count = 0
lock = threading.Lock()

def incre():
    global count
    caller = inspect.getouterframes(inspect.currentframe())[1][3]
    print "Inside %s()" % caller
    print "Acquiring lock"
    with lock:
        print "Lock Acquired"
        count += 1  
        time.sleep(2)  

def bye():
    while count < 5:
        incre()

def hello_there():
    while count < 5:
        incre()

def main():    
    hello = Thread(hello_there)
    goodbye = Thread(bye)


if __name__ == '__main__':
    main()

Sample output:

...
Inside hello_there()
Acquiring lock
Lock Acquired
Inside bye()
Acquiring lock
Lock Acquired
...

Walkthough on what is MUL, PRI and UNI in MySQL?

From the MySQL 5.7 documentation:

• If Key is PRI, the column is a PRIMARY KEY or is one of the columns in a multiple-column PRIMARY KEY.
• If Key is UNI, the column is the first column of a UNIQUE index. (A UNIQUE index permits multiple NULL values, but you can tell whether the column permits NULL by checking the Null field.)
• If Key is MUL, the column is the first column of a nonunique index in which multiple occurrences of a given value are permitted within the column.

Live Examples

Control group, this example has neither PRI, MUL, nor UNI:

mysql> create table penguins (foo INT);
Query OK, 0 rows affected (0.01 sec)

mysql> desc penguins;
+-------+---------+------+-----+---------+-------+
| Field | Type    | Null | Key | Default | Extra |

| foo   | int(11) | YES  |     | NULL    |       |
+-------+---------+------+-----+---------+-------+
1 row in set (0.00 sec)

A table with one column and an index on the one column has a MUL:

mysql> create table penguins (foo INT, index(foo));
Query OK, 0 rows affected (0.01 sec)

Stick that in your neocortex and set the dial to "frappe".

In the solution below I used python3.4 as binary, but it's safe to use with any version or binary of python. it works fine on windows too (except the downloading pip with wget obviously but just save the file locally and run it with python).

This is great if you have multiple versions of python installed, so you can manage external libraries per python version.

So first, I'd recommend get-pip.py, it's great to install pip :

wget https://bootstrap.pypa.io/get-pip.py

Then you need to install pip for your version of python, I have python3.4 so for me this is the command :

python3.4 get-pip.py

Now pip is installed for python3.4 and in order to get libraries for python3.4 one need to call it within this version, like this :

python3.4 -m pip

So if you want to install numpy you would use :

python3.4 -m pip install numpy

Note that numpy is quite the heavy library. I thought my system was hanging and failing. But using the verbose option, you can see that the system is fine :

python3.4 -m pip install numpy -v

This may tell you that you lack python.h but you can easily get it :

On RHEL (Red hat, CentOS, Fedora) it would be something like this :

yum install python34-devel

On debian-like (Debian, Ubuntu, Kali, ...) :

apt-get install python34-dev

Then rerun this :

python3.4 -m pip install numpy -v

I had a problem with the answer by @mwaskorn, namely that

g.set_xticklabels(rotation=30)

fails, because this also requires the labels. A bit easier than the answer by @Aman is to just add

plt.xticks(rotation=45)

I can't guarantee it's the simplest, but I like MarkerWithLabel. As shown in the basic example, CSS styles define the label's appearance and options in the JavaScript define the content and placement.

 .labels {
   color: red;
   background-color: white;
   font-family: "Lucida Grande", "Arial", sans-serif;
   font-size: 10px;
   font-weight: bold;
   text-align: center;
   width: 60px;     
   border: 2px solid black;
   white-space: nowrap;
 }

JavaScript:

 var marker = new MarkerWithLabel({
   position: homeLatLng,
   draggable: true,
   map: map,
   labelContent: "$425K",
   labelAnchor: new google.maps.Point(22, 0),
   labelClass: "labels", // the CSS class for the label
   labelStyle: {opacity: 0.75}
 });

The only part that may be confusing is the labelAnchor. By default, the label's top left corner will line up to the marker pushpin's endpoint. Setting the labelAnchor's x-value to half the width defined in the CSS width property will center the label. You can make the label float above the marker pushpin with an anchor point like new google.maps.Point(22, 50).

In case access to the links above are blocked, I copied and pasted the packed source of MarkerWithLabel into this JSFiddle demo. I hope JSFiddle is allowed in China :|

Based on different answers but mainly on this, this works for what I need:

UIImage *image1 = ...; // The image from where you want a pixel data
int pixelX = ...; // The X coordinate of the pixel you want to retrieve
int pixelY = ...; // The Y coordinate of the pixel you want to retrieve

uint32_t pixel1; // Where the pixel data is to be stored
CGContextRef context1 = CGBitmapContextCreate(&pixel1, 1, 1, 8, 4, CGColorSpaceCreateDeviceRGB(), kCGImageAlphaNoneSkipFirst);
CGContextDrawImage(context1, CGRectMake(-pixelX, -pixelY, CGImageGetWidth(image1.CGImage), CGImageGetHeight(image1.CGImage)), image1.CGImage);
CGContextRelease(context1);

As a result of this lines, you will have a pixel in AARRGGBB format with alpha always set to FF in the 4 byte unsigned integer pixel1.

This may be another way to go around lastrow. You may need to play around with the code to suit your needs

    function fill() {
      var spreadsheet = SpreadsheetApp.getActive();
      spreadsheet.getRange('a1').activate();
      var lsr = spreadsheet.getLastRow();
      lsr=lsr+1;
      lsr="A1:A"+lsr;

      spreadsheet.getActiveRange().autoFill(spreadsheet.getRange(lsr), SpreadsheetApp.AutoFillSeries.DEFAULT_SERIES);
};

Please note that android:windowSoftInputMode="adjustResize" does not work when WindowManager.LayoutParams.FLAG_FULLSCREENis set for an activity. You've got two options.

1. Either disable fullscreen mode for your activity. Activity is not re-sized in fullscreen mode. You can do this either in xml (by changing the theme of the activity) or in Java code. Add the following lines in your onCreate() method.

   getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);   
   getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);`
   

OR

2. Use an alternative way to achieve fullscreen mode. Add the following code in your onCreate() method.

   getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
   getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
   getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
   View decorView = getWindow().getDecorView();
   // Hide the status bar.
   int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
   decorView.setSystemUiVisibility(uiOptions);`
   

Please note that method-2 only works in Android 4.1 and above.

If you use the Eclipse "New Android Project" wizard in a recent ADT bundle, you'll automatically get tabs implemented as a Fragments. This makes the conversion of your application to the tablet format much easier in the future.

For simple single screen layouts you may still use Activity.

the best thing to do is :

def wordListToFreqDict(wordlist):
    wordfreq = [wordlist.count(p) for p in wordlist]
    return dict(zip(wordlist, wordfreq))

then try to : wordListToFreqDict(originallist)

There are quite a few working answers here, but I found this the easiest. This command will open up an editor, where you can just replace pick with squash in order to remove/merge them into one

git rebase -i HEAD~4

where, 4 is the number of commits you want to squash into one. This is explained here as well.

Add

session_start();

at the beginning of your page before any HTML

You will have something like :

<?php session_start();
include("inc/incfiles/header.inc.php")?>

Don't forget to remove the space you have before

The origin of this error lies in the fact that each and every promise is expected to handle promise rejection i.e. have a .catch(...) . you can avoid the same by adding .catch(...) to a promise in the code as given below.

for example, the function PTest() will either resolve or reject a promise based on the value of a global variable somevar

var somevar = false;
var PTest = function () {
    return new Promise(function (resolve, reject) {
        if (somevar === true)
            resolve();
        else
            reject();
    });
}
var myfunc = PTest();
myfunc.then(function () {
     console.log("Promise Resolved");
}).catch(function () {
     console.log("Promise Rejected");
});

In some cases, the "unhandled promise rejection" message comes even if we have .catch(..) written for promises. It's all about how you write your code. The following code will generate "unhandled promise rejection" even though we are handling catch.

var somevar = false;
var PTest = function () {
    return new Promise(function (resolve, reject) {
        if (somevar === true)
            resolve();
        else
            reject();
    });
}
var myfunc = PTest();
myfunc.then(function () {
     console.log("Promise Resolved");
});
// See the Difference here
myfunc.catch(function () {
     console.log("Promise Rejected");
});

The difference is that you don't handle .catch(...) as chain but as separate. For some reason JavaScript engine treats it as promise without un-handled promise rejection.

I just love getting information like BalusC gives here - and he is kind enough to help SO many people with such GOOD information that I regard his words as gospel, but I was not able to use that order of events to solve this same kind of timing issue in my project. Since BalusC put a great general reference here that I even bookmarked, I thought I would donate my solution for some advanced timing issues in the same place since it does solve the original poster's timing issues as well. I hope this code helps someone:

        <p:pickList id="formPickList" 
                    value="#{mediaDetail.availableMedia}" 
                    converter="MediaPicklistConverter" 
                    widgetVar="formsPicklistWidget" 
                    var="mediaFiles" 
                    itemLabel="#{mediaFiles.mediaTitle}" 
                    itemValue="#{mediaFiles}" >
            <f:facet name="sourceCaption">Available Media</f:facet>
            <f:facet name="targetCaption">Chosen Media</f:facet>
        </p:pickList>

        <p:commandButton id="viewStream_btn" 
                         value="Stream chosen media" 
                         icon="fa fa-download"
                         ajax="true"
                         action="#{mediaDetail.prepareStreams}"                                              
                         update=":streamDialogPanel"
                         oncomplete="PF('streamingDialog').show()"
                         styleClass="ui-priority-primary"
                         style="margin-top:5px" >
            <p:ajax process="formPickList"  />
        </p:commandButton>

The dialog is at the top of the XHTML outside this form and it has a form of its own embedded in the dialog along with a datatable which holds additional commands for streaming the media that all needed to be primed and ready to go when the dialog is presented. You can use this same technique to do things like download customized documents that need to be prepared before they are streamed to the user's computer via fileDownload buttons in the dialog box as well.

As I said, this is a more complicated example, but it hits all the high points of your problem and mine. When the command button is clicked, the result is to first insure the backing bean is updated with the results of the pickList, then tell the backing bean to prepare streams for the user based on their selections in the pick list, then update the controls in the dynamic dialog with an update, then show the dialog box ready for the user to start streaming their content.

The trick to it was to use BalusC's order of events for the main commandButton and then to add the <p:ajax process="formPickList" /> bit to ensure it was executed first - because nothing happens correctly unless the pickList updated the backing bean first (something that was not happening for me before I added it). So, yea, that commandButton rocks because you can affect previous, pending and current components as well as the backing beans - but the timing to interrelate all of them is not easy to get a handle on sometimes.

Happy coding!

This is a good example based on domain driven design and explains why it is important to have separate domain layer.

this might be repetitive. I was trying to use pycharm to run flask - had anaconda 3, pycharm 2019.1.1 and windows 10. Created a new conda environment - it threw errors. Followed these steps -

1. Used the cmd to install python and flask after creating environment as suggested above.

2. Followed this answer.

3. As suggested above, went to Run -> Edit Configurations and changed the environment there as well as in (2).

Obviously kept the correct python interpreter (the one in the environment) everywhere.

Neither a ":" nor a "." will show up in valid Base64, so I think you can unambiguously throw away the http://www.stackoverflow.com line. In Perl, say, something like

my $sanitized_str = join q{}, grep {!/[^A-Za-z0-9+\/=]/} split /\n/, $str;

say decode_base64($sanitized_str);

might be what you want. It produces

This is simple ASCII Base64 for StackOverflow exmaple.

No. ForEach just iterates through collection for each item and order depends whether it uses IEnumerable or GetEnumerator().

The variable in the for loop is an integer sequence, and so eventually you do this:

> y=as.integer(60000)*as.integer(60000)
Warning message:
In as.integer(60000) * as.integer(60000) : NAs produced by integer overflow

whereas in the while loop you are creating a floating point number.

Its also the reason these things are different:

> seq(0,2,1)
[1] 0 1 2
> seq(0,2)
[1] 0 1 2

Don't believe me?

> identical(seq(0,2),seq(0,2,1))
[1] FALSE

because:

> is.integer(seq(0,2))
[1] TRUE

It's possible, but it depends on the power output of the beacon you're receiving, other rf sources nearby, obstacles and other environmental factors. Best thing to do is try it out in the environment you're interested in.

It should be like this.

In your Component

computed: {
        ...mapGetters({
                nameFromStore: 'name'
            }),
        name: {
           get(){
             return this.nameFromStore
           },
           set(newName){
             return newName
           } 
        }
    }

In your store

export const store = new Vuex.Store({
         state:{
             name : "Stackoverflow"
         },
         getters: {
                 name: (state) => {
                     return state.name;
                 }
         }
}

Following the previous example but with the new nbformat lib version :

import nbformat
from nbconvert import PythonExporter

def convertNotebook(notebookPath, modulePath):

  with open(notebookPath) as fh:
    nb = nbformat.reads(fh.read(), nbformat.NO_CONVERT)

  exporter = PythonExporter()
  source, meta = exporter.from_notebook_node(nb)

  with open(modulePath, 'w+') as fh:
    fh.writelines(source.encode('utf-8'))

.a files are static libraries typically generated by the archive tool. You usually include the header files associated with that static library and then link to the library when you are compiling.

Give the div a fixed height and srcoll:hidden; and on hover change the scroll to auto;

#test_scroll{ height:300px; overflow:hidden;}
#test_scroll:hover{overflow-y:auto;}

Here is an example. http://jsfiddle.net/Lywpk/

One of the benefits is that Razor views can be rendered inside unit tests, this is something that was not easily possible with the previous ASP.Net renderer.

From ScottGu's announcement this is listed as one of the design goals:

Unit Testable: The new view engine implementation will support the ability to unit test views (without requiring a controller or web-server, and can be hosted in any unit test project – no special app-domain required).

Specifying the column type as serial for PostgreSQL to generate the id.

If you want to include render prop components:

  children: PropTypes.oneOfType([
    PropTypes.arrayOf(PropTypes.node),
    PropTypes.node,
    PropTypes.func
  ])

Assuming a string 's'

palin = lambda s: s[:(len(s)/2 + (0 if len(s)%2==0 else 1)):1] == s[:len(s)/2-1:-1]  
# Test
palin('654456')  # True
palin('malma')   # False
palin('ab1ba')   # True

I really had troubles with those examples from Andy Arismendi and from LPG. You should always use:

$stdout = $p.StandardOutput.ReadToEnd()

before calling

$p.WaitForExit()

A full example is:

$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pinfo.FileName = "ping.exe"
$pinfo.RedirectStandardError = $true
$pinfo.RedirectStandardOutput = $true
$pinfo.UseShellExecute = $false
$pinfo.Arguments = "localhost"
$p = New-Object System.Diagnostics.Process
$p.StartInfo = $pinfo
$p.Start() | Out-Null
$stdout = $p.StandardOutput.ReadToEnd()
$stderr = $p.StandardError.ReadToEnd()
$p.WaitForExit()
Write-Host "stdout: $stdout"
Write-Host "stderr: $stderr"
Write-Host "exit code: " + $p.ExitCode

Here is a filter that will take a date string OR javascript Date() object. It uses Moment.js and can apply any Moment.js transform function, such as the popular 'fromNow'

angular.module('myModule').filter('moment', function () {
  return function (input, momentFn /*, param1, param2, ...param n */) {
    var args = Array.prototype.slice.call(arguments, 2),
        momentObj = moment(input);
    return momentObj[momentFn].apply(momentObj, args);
  };
});

So...

{{ anyDateObjectOrString | moment: 'format': 'MMM DD, YYYY' }}

would display Nov 11, 2014

{{ anyDateObjectOrString | moment: 'fromNow' }}

would display 10 minutes ago

If you need to call multiple moment functions, you can chain them. This converts to UTC and then formats...

{{ someDate | moment: 'utc' | moment: 'format': 'MMM DD, YYYY' }}

I like being able to use foreach, so I made an extension method and a structure:

public struct EnumeratedInstance<T>
{
    public long cnt;
    public T item;
}

public static IEnumerable<EnumeratedInstance<T>> Enumerate<T>(this IEnumerable<T> collection)
{
    long counter = 0;
    foreach (var item in collection)
    {
        yield return new EnumeratedInstance<T>
        {
            cnt = counter,
            item = item
        };
        counter++;
    }
}

and an example use:

foreach (var ii in new string[] { "a", "b", "c" }.Enumerate())
{
    Console.WriteLine(ii.item + ii.cnt);
}

One nice thing is that if you are used to the Python syntax, you can still use it:

foreach (var ii in Enumerate(new string[] { "a", "b", "c" }))

Since the release of Android Oreo and its support library (26.0.0) you can do this easily. Refer to this answer in another question.

Basically your final style will look like this:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
   <item name="fontFamily">@font/your_font</item> <!-- target android sdk versions < 26 and > 14 -->
</style>

AFAIK you can't do an if else in batch like you can in other languages, it has to be nested if's.

Using nested if's your batch would look like

IF %F%==1 IF %C%==1(
    ::copying the file c to d
    copy "%sourceFile%" "%destinationFile%"
    ) ELSE (
        IF %F%==1 IF %C%==0(
        ::moving the file c to d
        move "%sourceFile%" "%destinationFile%"
        ) ELSE (
            IF %F%==0 IF %C%==1(
            ::copying a directory c from d, /s:  bos olanlar hariç, /e:bos olanlar dahil
            xcopy "%sourceCopyDirectory%" "%destinationCopyDirectory%" /s/e
            ) ELSE (
                IF %F%==0 IF %C%==0(
                ::moving a directory
                xcopy /E "%sourceMoveDirectory%" "%destinationMoveDirectory%"
                rd /s /q "%sourceMoveDirectory%"
                )
            )
        )
    )

or as James suggested, chain your if's, however I think the proper syntax is

IF %F%==1 IF %C%==1(
    ::copying the file c to d
    copy "%sourceFile%" "%destinationFile%"
    )

Use the recursive switch --recursive (-R)

svn revert -R .

Here dataTpe is "json" so, data/reqParam must be in the form of string while calling API, many as much as object as you want but at last inside $.ajax's data stringify the object.

             let person= {  name: 'john',
                age: 22
            };

           var personStr = JSON.stringify(person); 

            $.ajax({
                url: "@Url.Action("METHOD", "CONTROLLER")",
                type: "POST",
                data: JSON.stringify( { param1: personStr } ),
                contentType: "application/json;charset=utf-8",
                dataType: "json",
        success: function (response) {

            console.log("Success");

        },
        error: function (error) {
            console.log("error found",error);
        }
    });

OR,

       $.ajax({
                url: "@Url.Action("METHOD", "CONTROLLER")",
                type: "POST",
                data: personStr,
                contentType: "application/json;charset=utf-8",
                dataType: "json",
        success: function (response) {

            console.log("Success");

        },
        error: function (error) {
            console.log("error found",error);
        }
    });

This should be fairly straightforward in the gimp http://gimp.org/

First make sure your image is RGB (not indexed color) then use the "color to alpha" feature to turn the clubs/diamonds clear, then fill or set the background or whatever to get the color you want.

EDIT: While this is currently accepted answer, readers might find this other answer by user John Hart more adapted to their needs. It uses an option which, according to user Ken, was introduced in version 7.21.3 (which was released in December 2010, i.e. after this initial answer).

In your edited question, you're using the URL as the host name, whereas it needs to be the host name only.

Try:

curl -H 'Host: project1.loc' http://127.0.0.1/something

where project1.loc is just the host name and 127.0.0.1 is the target IP address.

(If you're using curl from a library and not on the command line, make sure you don't put http:// in the Host header.)

I encountered the same problem, and I fix it by creating a new subclass of UIButton and overriding the layoutSubviews: method as below :

-(void)layoutSubviews {
    [super layoutSubviews];

    // Center image
    CGPoint center = self.imageView.center;
    center.x = self.frame.size.width/2;
    center.y = self.imageView.frame.size.height/2;
    self.imageView.center = center;

    //Center text
    CGRect newFrame = [self titleLabel].frame;
    newFrame.origin.x = 0;
    newFrame.origin.y = self.imageView.frame.size.height + 5;
    newFrame.size.width = self.frame.size.width;

    self.titleLabel.frame = newFrame;
    self.titleLabel.textAlignment = UITextAlignmentCenter;

}

I think that the Angel García Olloqui's answer is another good solution, if you place all of them manually with interface builder but I'll keep my solution since I don't have to modify the content insets for each of my button.

Their Documentation says:

Cut and paste:

1. Position the cursor where you want to begin cutting.
2. Press v to select characters (or uppercase V to select whole lines).
3. Move the cursor to the end of what you want to cut.
4. Press d to cut (or y to copy).
5. Move to where you would like to paste.
6. Press P to paste before the cursor, or p to paste after.

Copy and paste is performed with the same steps except for step 4 where you would press y instead of d:

d = delete = cut

y = yank = copy

You are probably connecting fine but don't have sufficient privileges to run show dbs.

You don't need to run the db.auth if you pass the auth in the command line:

mongo somewhere.mongolayer.com:10011/my_database -u username -p password

Once you connect are you able to see collections?

> show collections

If so all is well and you just don't have admin privileges to the database and can't run the show dbs

React components expose all the standard Javascript mouse events in their top-level interface. Of course, you can still use :hover in your CSS, and that may be adequate for some of your needs, but for the more advanced behaviors triggered by a hover you'll need to use the Javascript. So to manage hover interactions, you'll want to use onMouseEnter and onMouseLeave. You then attach them to handlers in your component like so:

<ReactComponent
    onMouseEnter={() => this.someHandler}
    onMouseLeave={() => this.someOtherHandler}
/>

You'll then use some combination of state/props to pass changed state or properties down to your child React components.

For me it worked using flexbox, which is in my opinion the cleanest solution.

Add a css class around the parent div / element with :

.parent {
display: flex;
}

and for the button use:

.button {
justify-content: center;
}

You should use a parent div, otherwise the button doesn't 'know' what the middle of the page / element is.

If this is not working, try :

#wrapper {
    display:flex;
    justify-content: center;
}

This is the simple code that will work for you best on all popups that has any input field with focusing it

$(".modal").on('shown.bs.modal', function () {
    $(this).find("input:visible:first").focus();
});

Once you click the item add some data attribute like data-selected-item='true' and get it again.

Try adding data-selected-item='true' for li element that you clicked, then

   $('ul.dropdown-menu li[data-selected-item] a').text();

Before adding this attribute you simply remove existing data-selected-item in the list. Hope this would help you

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

You could try to reinstall the ca-certificates package, or explicitly allow the certificate in question as described here.

I prefer this solution using the csv module from the standard library and the with statement to avoid leaving the file open.

The key point is using 'a' for appending when you open the file.

import csv   
fields=['first','second','third']
with open(r'name', 'a') as f:
    writer = csv.writer(f)
    writer.writerow(fields)

If you are using Python 2.7 you may experience superfluous new lines in Windows. You can try to avoid them using 'ab' instead of 'a' this will, however, cause you TypeError: a bytes-like object is required, not 'str' in python and CSV in Python 3.6. Adding the newline='', as Natacha suggests, will cause you a backward incompatibility between Python 2 and 3.

minitech is right in that animation-delay specifies the delay before the animation starts and NOT the delay in between iterations. The editors draft of the spec describes it well and there was a discussion of this feature you're describing here which suggesting this iteration delay feature.

While there may be a workaround in JS, you can fake this iteration delay for the progress bar flare using only CSS.

By declaring the flare div position:absolute and the parent div overflow: hidden, setting the 100% keyframe state greater than the width of the progress bar, and playing around with the cubic-bezier timing function and left offset values, you're able to emulate an ease-in-out or linear timing with a "delay".

It'd be interesting to write a less/scss mixin to calculate exactly the left offset and timing function to get this exact, but I don't have the time at the moment to fiddle with it. Would love to see something like that though!

Here's a demo I threw together to show this off. (I tried to emulate the windows 7 progress bar and fell a bit short, but it demonstrates what I'm talking about)

See the Create a video slideshow from images – FFmpeg

If your video does not show the frames correctly If you encounter problems, such as the first image is skipped or only shows for one frame, then use the fps video filter instead of -r for the output framerate

ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -vf fps=25 -pix_fmt yuv420p out.mp4

Alternatively the format video filter can be added to the filter chain to replace -pix_fmt yuv420p like "fps=25,format=yuv420p". The advantage of this method is that you can control which filter goes first

ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -vf "fps=25,format=yuv420p" out.mp4

I tested below parameters, it worked for me

"e:\ffmpeg\ffmpeg.exe" -r 1/5 -start_number 0 -i "E:\images\01\padlock%3d.png" -c:v libx264 -vf "fps=25,format=yuv420p" e:\out.mp4

below parameters also worked but it always skips the first image

"e:\ffmpeg\ffmpeg.exe" -r 1/5 -start_number 0 -i "E:\images\01\padlock%3d.png" -c:v libx264 -r 30 -pix_fmt yuv420p e:\out.mp4

making a video from images placed in different folders

First, add image paths to imagepaths.txt like below.

# this is a comment details https://trac.ffmpeg.org/wiki/Concatenate

file 'E:\images\png\images__%3d.jpg'
file 'E:\images\jpg\images__%3d.jpg'

Sample usage as follows;

"h:\ffmpeg\ffmpeg.exe" -y -r 1/5 -f concat -safe 0 -i "E:\images\imagepaths.txt" -c:v libx264 -vf "fps=25,format=yuv420p" "e:\out.mp4"

-safe 0 parameter prevents Unsafe file name error

It tells you at the very start of the tutorial linked from the jQuery homepage.

Just found this out the hard way.

Using React with Redux, the state container of which's keys I want to traverse in order to generate children is refreshed everytime the store is changed (as per Redux's immutability concepts).

Thus, in order to take Object.keys(valueFromStore) I used Object.keys(valueFromStore).sort(), so that I at least now have an alphabetical order for the keys.

You must use a tool called a "header". In a header you declare the function that you want to use. Then you include it in both files. A header is a separate file included using the #include directive. Then you may call the other function.

other.h

void MyFunc();

main.cpp

#include "other.h"
int main() {
    MyFunc();
}

other.cpp

#include "other.h"
#include <iostream>
void MyFunc() {
    std::cout << "Ohai from another .cpp file!";
    std::cin.get();
}

This can also occur if you are using a persisted model cache which is out of date for one reason or another. If your context has been cached to an EDMX file on a file system (via DbConfiguration.SetModelStore) then OnModelCreating will never be called as the cached version will be used. As a result if an entity is missing from your cached store then you will get the above error even though the connection string is correct, the table exists in the database and the entity is set up correctly in your DbContext.

None of these solutions worked for me since I wanted to find peaks in the center of repeating values as well. for example, in

ar = np.array([0,1,2,2,2,1,3,3,3,2,5,0])

the answer should be

array([ 3,  7, 10], dtype=int64)

I did this using a loop. I know it's not super clean, but it gets the job done.

def findLocalMaxima(ar):
# find local maxima of array, including centers of repeating elements    
maxInd = np.zeros_like(ar)
peakVar = -np.inf
i = -1
while i < len(ar)-1:
#for i in range(len(ar)):
    i += 1

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

Something like:

library(dplyr)

df <- data.frame(id=c(1,1,1,2,2,2,3,3,3),
                 stopId=c("a","b","c","a","b","c","a","b","c"),
                 stopSequence=c(1,2,3,3,1,4,3,1,2))

first_last <- function(x) {
  bind_rows(slice(x, 1), slice(x, n()))
}

df %>%
  group_by(id) %>%
  arrange(stopSequence) %>%
  do(first_last(.)) %>%
  ungroup

## Source: local data frame [6 x 3]
## 
##   id stopId stopSequence
## 1  1      a            1
## 2  1      c            3
## 3  2      b            1
## 4  2      c            4
## 5  3      b            1
## 6  3      a            3

With do you can pretty much perform any number of operations on the group but @jeremycg's answer is way more appropriate for just this task.

I would like to suggest to use a single RecyclerView and populate your list items dynamically. I've added a github project to describe how this can be done. You might have a look. While the other solutions will work just fine, I would like to suggest, this is a much faster and efficient way of showing multiple lists in a RecyclerView.

The idea is to add logic in your onCreateViewHolder and onBindViewHolder method so that you can inflate proper view for the exact positions in your RecyclerView.

I've added a sample project along with that wiki too. You might clone and check what it does. For convenience, I am posting the adapter that I have used.

public class DynamicListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private static final int FOOTER_VIEW = 1;
    private static final int FIRST_LIST_ITEM_VIEW = 2;
    private static final int FIRST_LIST_HEADER_VIEW = 3;
    private static final int SECOND_LIST_ITEM_VIEW = 4;
    private static final int SECOND_LIST_HEADER_VIEW = 5;

    private ArrayList<ListObject> firstList = new ArrayList<ListObject>();
    private ArrayList<ListObject> secondList = new ArrayList<ListObject>();

    public DynamicListAdapter() {
    }

    public void setFirstList(ArrayList<ListObject> firstList) {
        this.firstList = firstList;
    }

    public void setSecondList(ArrayList<ListObject> secondList) {
        this.secondList = secondList;
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        // List items of first list
        private TextView mTextDescription1;
        private TextView mListItemTitle1;

        // List items of second list
        private TextView mTextDescription2;
        private TextView mListItemTitle2;

        // Element of footer view
        private TextView footerTextView;

        public ViewHolder(final View itemView) {
            super(itemView);

            final String description = secondList.get(pos).getDescription();
            final String title = secondList.get(pos).getTitle();

            mTextDescription2.setText(description);

There is another way of keeping your items in a single ArrayList of objects so that you can set an attribute tagging the items to indicate which item is from first list and which one belongs to second list. Then pass that ArrayList into your RecyclerView and then implement the logic inside adapter to populate them dynamically.

Hope that helps.

Strictly speaking, the concept of a callback function does not exist in Java, because in Java there are no functions, only methods, and you cannot pass a method around, you can only pass objects and interfaces. So, whoever has a reference to that object or interface may invoke any of its methods, not just one method that you might wish them to.

However, this is all fine and well, and we often speak of callback objects and callback interfaces, and when there is only one method in that object or interface, we may even speak of a callback method or even a callback function; we humans tend to thrive in inaccurate communication.

(Actually, perhaps the best approach is to just speak of "a callback" without adding any qualifications: this way, you cannot possibly go wrong. See next sentence.)

One of the most famous examples of using a callback in Java is when you call an ArrayList object to sort itself, and you supply a comparator which knows how to compare the objects contained within the list.

Your code is the high-level layer, which calls the lower-level layer (the standard java runtime list object) supplying it with an interface to an object which is in your (high level) layer. The list will then be "calling back" your object to do the part of the job that it does not know how to do, namely to compare elements of the list. So, in this scenario the comparator can be thought of as a callback object.

Scanner scanner = new Scanner(System.in);
int employeeId, supervisorId;
String name;
System.out.println("Enter employee ID:");
employeeId = scanner.nextInt();
scanner.nextLine(); //This is needed to pick up the new line
System.out.println("Enter employee name:");
name = scanner.nextLine();
System.out.println("Enter supervisor ID:");
supervisorId = scanner.nextInt();

Calling nextInt() was a problem as it didn't pick up the new line (when you hit enter). So, calling scanner.nextLine() after that does the work.

So we are all doing the same home work?

Strange how the most up-voted answer is wrong. Remember, draw/fillOval take height and width as parameters, not the radius. So to correctly draw and center a circle with user-provided x, y, and radius values you would do something like this:

public static void drawCircle(Graphics g, int x, int y, int radius) {

  int diameter = radius * 2;

  //shift x and y by the radius of the circle in order to correctly center it
  g.fillOval(x - radius, y - radius, diameter, diameter); 

}

The hex values are on the mainpage of http://glyphicons.com/ in the tooltips of the specific icon.

Edit your C:\Windows\System32\drivers\etc\hosts file

Make sure there is an entry that looks like this:

127.0.0.1   localhost

If there is an entry like

::  localhost

Comment it out to look like this

\#:: localhost

This should fix your problem, I've had this problem in the past.

Not just specific to MySQL, the difference between float and decimal types is the way that they represent fractional values. Floating point types represent fractions in binary, which can only represent values as {m*2^n | m, n Integers} . values such as 1/5 cannot be precisely represented (without round off error). Decimal numbers are similarly limited, but represent numbers like {m*10^n | m, n Integers}. Decimals still cannot represent numbers like 1/3, but it is often the case in many common fields, like finance, that the expectation is that certain decimal fractions can always be expressed without loss of fidelity. Since a decimal number can represent a value like $0.20 (one fifth of a dollar), it is preferred in those situations.

The Y array in your screenshot is not a 1D array, it's a 2D array with 300 rows and 1 column, as indicated by its shape being (300, 1).

To remove the extra dimension, you can slice the array as Y[:, 0]. To generally convert an n-dimensional array to 1D, you can use np.reshape(a, a.size).

Another option for converting a 2D array into 1D is flatten() function from numpy.ndarray module, with the difference that it makes a copy of the array.

This happened to me today. I was able to track down the cause: The project included a header file which no longer existed on disk.

Removing the file from the project solved the problem.

BTW. you should prefer coding against an Interface.

private ArrayList<String[]> action = new ArrayList<String[]>();

Should be

private List<String[]> action = new ArrayList<String[]>();

Use a comma to specify a port number with SQL Server:

mycomputer.test.xxx.com,1234

It's not necessary to specify an instance name when specifying the port.

Lots more examples at http://www.connectionstrings.com/. It's saved me a few times.

Well you can convert one byte (unsigned char) at a time into a array like so

char buffer [17];
buffer[16] = 0;
for(j = 0; j < 8; j++)
    sprintf(&buffer[2*j], "%02X", data[j]);

I'm passing to Django's template a function, which returns me some records

Why don't you pass to Django template the variable storing function's return value, instead of the function?

I've tried to set fuction's return value to a variable and iterate over variable, but there seems to be no way to set variable in Django template.

You should set variables in Django views instead of templates, and then pass them to the template.

The server directive has to be in the http directive. It should not be outside of it.

Incase if you need detailed information, refer this.

Just download this registry key and run it. It will add the necessary key to the .NET framework registry. You can have more info at this link. Search for 'Option 2' in '.NET 4.5 to 4.5.2'.

The reg file appends the following to the Registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

This is the part of the page that is useful in case it goes broken :

" .. enable TLS 1.2 by default without modifying the source code by setting the SchUseStrongCrypto DWORD value in the following two registry keys to 1, creating them if they don't exist: "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319" and "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft.NETFramework\v4.0.30319". Although the version number in those registry keys is 4.0.30319, the .NET 4.5, 4.5.1, and 4.5.2 frameworks also use these values. Those registry keys, however, will enable TLS 1.2 by default in all installed .NET 4.0, 4.5, 4.5.1, and 4.5.2 applications on that system. It is thus advisable to test this change before deploying it to your production servers. This is also available as a registry import file. These registry values, however, will not affect .NET applications that set the System.Net.ServicePointManager.SecurityProtocol value. "

In jQuery:

$('some_element').keypress(function(e){
       if(e.keyCode == 20){
             //caps lock was pressed
       }
});

This jQuery plugin (code) implements the same idea as in Rajesh's answer a bit more succinctly.

I thought it would be:

byte b = (byte)255;
int i = b &255;

Perhaps something like this, assuming that there are many of these rows inside of the datatable and that each row is row:

List<string[]> MyStringArrays = new List<string[]>();
foreach( var row in datatable.rows )//or similar
{
 MyStringArrays.Add( new string[]{row.Name,row.Address,row.Age.ToString()} );
}

You could then access one:

MyStringArrays.ElementAt(0)[1]

If you use linqpad, here is a very simple scenario of your example:

class Datatable
{
 public List<data> rows { get; set; }
 public Datatable(){
  rows = new List<data>();
 }
}

class data
{
 public string Name { get; set; }
 public string Address { get; set; }
 public int Age { get; set; }
}

void Main()
{
 var datatable = new Datatable();
 var r = new data();
 r.Name = "Jim";
 r.Address = "USA";
 r.Age = 23;
 datatable.rows.Add(r);
 List<string[]> MyStringArrays = new List<string[]>();
 foreach( var row in datatable.rows )//or similar
 {
  MyStringArrays.Add( new string[]{row.Name,row.Address,row.Age.ToString()} );
 }
 var s = MyStringArrays.ElementAt(0)[1];
 Console.Write(s);//"USA"
}

Consider using the Apache Commons UrlValidator class

UrlValidator urlValidator = new UrlValidator();
urlValidator.isValid("http://my favorite site!");

There are several properties that you can set to control how this class behaves, by default http, https, and ftp are accepted.

You have to have single quotes around any VARCHAR content in your queries. So your update query should be:

mysql_query("UPDATE blogEntry SET content = '$udcontent', title = '$udtitle' WHERE id = $id");

Also, it is bad form to update your database directly with the content from a POST. You should sanitize your incoming data with the mysql_real_escape_string function.

Concatenating the querysets into a list is the simplest approach. If the database will be hit for all querysets anyway (e.g. because the result needs to be sorted), this won't add further cost.

from itertools import chain
result_list = list(chain(page_list, article_list, post_list))

Using itertools.chain is faster than looping each list and appending elements one by one, since itertools is implemented in C. It also consumes less memory than converting each queryset into a list before concatenating.

Now it's possible to sort the resulting list e.g. by date (as requested in hasen j's comment to another answer). The sorted() function conveniently accepts a generator and returns a list:

result_list = sorted(
    chain(page_list, article_list, post_list),
    key=lambda instance: instance.date_created)

If you're using Python 2.4 or later, you can use attrgetter instead of a lambda. I remember reading about it being faster, but I didn't see a noticeable speed difference for a million item list.

from operator import attrgetter
result_list = sorted(
    chain(page_list, article_list, post_list),
    key=attrgetter('date_created'))

Change this:

public FrameForm() { 
    initComponents(); 
}

to this:

public FrameForm() {
    initComponents();
    this.setLocationRelativeTo(null);
}

In windows, you can use _getch() in the

<conio.h>

header.

var fileName = string.Format("{0}\\fileNameHere", Directory.GetCurrentDirectory());
var connectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=Excel 8.0;", fileName);

var adapter = new OleDbDataAdapter("SELECT * FROM [workSheetNameHere$]", connectionString);
var ds = new DataSet();

adapter.Fill(ds, "anyNameHere");

DataTable data = ds.Tables["anyNameHere"];

This is what I usually use. It is a little different because I usually stick a AsEnumerable() at the edit of the tables:

var data = ds.Tables["anyNameHere"].AsEnumerable();

as this lets me use LINQ to search and build structs from the fields.

var query = data.Where(x => x.Field<string>("phoneNumber") != string.Empty).Select(x =>
                new MyContact
                    {
                        firstName= x.Field<string>("First Name"),
                        lastName = x.Field<string>("Last Name"),
                        phoneNumber =x.Field<string>("Phone Number"),
                    });

I would use python-dpkt. Here is the documentation: http://www.commercialventvac.com/dpkt.html

This is all I know how to do though sorry.

#!/usr/local/bin/python2.7

import dpkt

counter=0
ipcounter=0
tcpcounter=0
udpcounter=0

filename='sampledata.pcap'

for ts, pkt in dpkt.pcap.Reader(open(filename,'r')):

    counter+=1
    eth=dpkt.ethernet.Ethernet(pkt) 
    if eth.type!=dpkt.ethernet.ETH_TYPE_IP:
       continue

    ip=eth.data
    ipcounter+=1

    if ip.p==dpkt.ip.IP_PROTO_TCP: 
       tcpcounter+=1

    if ip.p==dpkt.ip.IP_PROTO_UDP:
       udpcounter+=1

print "Total number of packets in the pcap file: ", counter
print "Total number of ip packets: ", ipcounter
print "Total number of tcp packets: ", tcpcounter
print "Total number of udp packets: ", udpcounter

In MAC OS Catalina, this are the steps that worked for me, all the above solutions did help but didn't solve my problem.

1. check node --version, still the old one in use.
2. cd ~/
3. atom .bash_profile
4. Remove the $PATH pointing to old node version, in my case it was /usr/local/bin/node/@node8
5. Add & save this to $PATH instead "export PATH=$PATH:/usr/local/git/bin:/usr/local/bin"
6. Close all applications using node (terminal, simulator, browser expo etc)
7. restart terminal and check node --version

You can plot several columns at once by supplying a list of column names to the plot's y argument.

df.plot(x="X", y=["A", "B", "C"], kind="bar")

This will produce a graph where bars are sitting next to each other.

In order to have them overlapping, you would need to call plot several times, and supplying the axes to plot to as an argument ax to the plot.

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

y = np.random.rand(10,4)
y[:,0]= np.arange(10)
df = pd.DataFrame(y, columns=["X", "A", "B", "C"])

ax = df.plot(x="X", y="A", kind="bar")
df.plot(x="X", y="B", kind="bar", ax=ax, color="C2")
df.plot(x="X", y="C", kind="bar", ax=ax, color="C3")

plt.show()

You need to add your ORACLE_HOME definition in your listener.ora file. Right now its not registered with any ORACLE_HOME.

Sample listener.ora

abc =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = abc.kma.com)(PORT = 1521))
    )
  )

SID_LIST_abc =
  (SID_LIST =
    (SID_DESC =
      (ORACLE_HOME= /abc/DbTier/11.2.0)
      (SID_NAME = abc)
    )
  )

To stop the Xcode 8 iOS Simulator from logging like crazy, set an environment variable OS_ACTIVITY_MODE = disable in your debug scheme.

It worked.

I ran into this issue and my problem was a bit more involved... Originally I was trying to restore a SQL Server 2000 backup to SQL Server 2012. Of course this didn't work cause SQL server 2012 only supports backups from 2005 and upwards .

So, I restored the database on a SQL Server 2008 machine. Once this was done - I copied the database over to restore on SQL Server 2012 - and it failed with the following error

The media family on device 'C:\XXXXXXXXXXX.bak' is incorrectly formed. SQL Server cannot process this media family. RESTORE HEADERONLY is terminating abnormally. (Microsoft SQL Server, Error: 3241)

After a lot of research I found that I had skipped a step - I had to go back to the SQL Server 2008 machine and Right Click On the database(that I wanted to backup)> Properties > Options > Make sure compatibility level is set to SQL Server 2008. > Save

And then re-create the backup - After this I was able to restore to SQL Server 2012.

This code will alert the selected radio button when the form is submitted. It used jQuery to get the selected value.

$("form").submit(function(e) {_x000D_
  e.preventDefault();_x000D_
  $this = $(this);_x000D_
_x000D_
  var value = $this.find('input:radio[name=COLOR]:checked').val();_x000D_
  alert(value);_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<form>_x000D_
  <input name="COLOR" id="Rojo" type="radio" value="red">_x000D_
  <input name="COLOR" id="Azul" type="radio" value="blue">_x000D_
  <input name="COLOR" id="Amarillo" type="radio" value="yellow">_x000D_
  <br>_x000D_
  <input type="submit" value="Submit">_x000D_

Relatively-position your content div within a parent div having overflow:hidden. Make your up/down arrows move the top value of the content div. The following jQuery is untested. Let me know if you require any further assistance with it as a concept.

div.container {
  overflow:hidden;
  width:200px;
  height:200px;
}
div.content {
  position:relative;
  top:0;
}

<div class="container">
  <p>
    <a href="enablejs.html" class="up">Up</a> / 
    <a href="enablejs.html" class="dn">Down</a>
  </p>
  <div class="content">
    <p>Hello World</p>
  </div>
</div>

$(function(){
  $(".container a.up").bind("click", function(){
    var topVal = $(this).parents(".container").find(".content").css("top");
    $(this).parents(".container").find(".content").css("top", topVal-10);
  });

  $(".container a.dn").bind("click", function(){
    var topVal = $(this).parents(".container").find(".content").css("top");
    $(this).parents(".container").find(".content").css("top", topVal+10);
  });
});

String formatterPhone = String.format("%s-%s-%s", phoneNumber.substring(0, 3), phoneNumber.substring(3, 6), phoneNumber.substring(6, 10));

As Drew Taylor pointed out, branch deletion with -d only considers the current HEAD in determining if the branch is "fully merged". It will complain even if the branch is merged with some other branch. The error message could definitely be clearer in this regard... You can either checkout the merged branch before deleting, or just use git branch -D. The capital -D will override the check entirely.

The best place to start looking is http://api.jquery.com/category/selectors/

This will give you a good set of examples.

Ultamatly the selecting of elements in the DOM is achived using CSS selectors so if you think about getting an element by id you will want to use $('#elementId'), if you want all the input tags use $('input') and finaly the part i think you'll want if you want all input tags with a type of checkbox use $('input, [type=checkbox])

Note: You'll find most of the values you want are on attributes so the css selector for attributes is: [attributeName=value]

Just because you asked for the dropdown as aposed to a listbox try the following:

$('select, [size]).each(function(){
  var selectedItem = $('select, [select]', this).first();
});

The code was from memory so please accound for small errors

$(window).scroll(function() {    
    var scroll = $(window).scrollTop();

     //>=, not <=
    if (scroll >= 500) {
        //clearHeader, not clearheader - caps H
        $(".clearHeader").addClass("darkHeader");
    }
}); //missing );

Fiddle

Also, by removing the clearHeader class, you're removing the position:fixed; from the element as well as the ability of re-selecting it through the $(".clearHeader") selector. I'd suggest not removing that class and adding a new CSS class on top of it for styling purposes.

And if you want to "reset" the class addition when the users scrolls back up:

$(window).scroll(function() {    
    var scroll = $(window).scrollTop();

    if (scroll >= 500) {
        $(".clearHeader").addClass("darkHeader");
    } else {
        $(".clearHeader").removeClass("darkHeader");
    }
});

Fiddle

edit: Here's version caching the header selector - better performance as it won't query the DOM every time you scroll and you can safely remove/add any class to the header element without losing the reference:

$(function() {
    //caches a jQuery object containing the header element
    var header = $(".clearHeader");
    $(window).scroll(function() {
        var scroll = $(window).scrollTop();

        if (scroll >= 500) {
            header.removeClass('clearHeader').addClass("darkHeader");
        } else {
            header.removeClass("darkHeader").addClass('clearHeader');
        }
    });
});

Fiddle

>>> x = [0, 1, 2, 3, 4]
>>> x.pop(0)
0

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

If you are on Windows and have Visual Studio installed you might have something in your PATH that is pointing to an old version of TypeScript. I found that removing the folder "C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\" from my PATH (or deleting/renaming this folder) will allow the more recent npm globally installed TypeScript version of tsc to work.

In this bit of code:

getRadioButtonValue(this["whichThing"]))

you're not actually getting a reference to anything. Therefore, your radiobutton in the getradiobuttonvalue function is undefined and throwing an error.

EDIT To get the value out of the radio buttons, grab the JQuery library, and then use this:

  $('input[name=whichThing]:checked').val() 

Edit 2 Due to the desire to reinvent the wheel, here's non-Jquery code:

var t = '';
for (i=0; i<document.myform.whichThing.length; i++) {
     if (document.myform.whichThing[i].checked==true) {
         t = t + document.myform.whichThing[i].value;
     }
}

or, basically, modify the original line of code to read thusly:

getRadioButtonValue(document.myform.whichThing))

Edit 3 Here's your homework:

      function handleClick() {
        alert("Favorite weird creature: " + getRadioButtonValue(document.aye.whichThing));
        //event.preventDefault(); // disable normal form submit behavior
        return false; // prevent further bubbling of event
      }
    </script>
  </head>
<body>
<form name="aye" onSubmit="return handleClick()">
     <input name="Submit"  type="submit" value="Update" />
     Which of the following do you like best?
     <p><input type="radio" name="whichThing" value="slithy toves" />Slithy toves</p>
     <p><input type="radio" name="whichThing" value="borogoves" />Borogoves</p>
     <p><input type="radio" name="whichThing" value="mome raths" />Mome raths</p>
</form>

Notice the following, I've moved the function call to the Form's "onSubmit" event. An alternative would be to change your SUBMIT button to a standard button, and put it in the OnClick event for the button. I also removed the unneeded "JavaScript" in front of the function name, and added an explicit RETURN on the value coming out of the function.

In the function itself, I modified the how the form was being accessed. The structure is: document.[THE FORM NAME].[THE CONTROL NAME] to get at things. Since you renamed your from aye, you had to change the document.myform. to document.aye. Additionally, the document.aye["whichThing"] is just wrong in this context, as it needed to be document.aye.whichThing.

The final bit, was I commented out the event.preventDefault();. that line was not needed for this sample.

EDIT 4 Just to be clear. document.aye["whichThing"] will provide you direct access to the selected value, but document.aye.whichThing gets you access to the collection of radio buttons which you then need to check. Since you're using the "getRadioButtonValue(object)" function to iterate through the collection, you need to use document.aye.whichThing.

See the difference in this method:

function handleClick() {
   alert("Direct Access: " + document.aye["whichThing"]);
   alert("Favorite weird creature: " + getRadioButtonValue(document.aye.whichThing));
   return false; // prevent further bubbling of event
}

This is the correct way:

You should declare the length of the array after "="

Veicle[] cars = new Veicle[N];

The map() function is there to apply the same procedure to every item in an iterable data structure, like lists, generators, strings, and other stuff.

Let's look at an example: map() can iterate over every item in a list and apply a function to each item, than it will return (give you back) the new list.

Imagine you have a function that takes a number, adds 1 to that number and returns it:

def add_one(num):
  new_num = num + 1
  return new_num

You also have a list of numbers:

my_list = [1, 3, 6, 7, 8, 10]

if you want to increment every number in the list, you can do the following:

>>> map(add_one, my_list)
[2, 4, 7, 8, 9, 11]

Note: At minimum map() needs two arguments. First a function name and second something like a list.

Let's see some other cool things map() can do. map() can take multiple iterables (lists, strings, etc.) and pass an element from each iterable to a function as an argument.

We have three lists:

list_one = [1, 2, 3, 4, 5]
list_two = [11, 12, 13, 14, 15]
list_three = [21, 22, 23, 24, 25]

map() can make you a new list that holds the addition of elements at a specific index.

Now remember map(), needs a function. This time we'll use the builtin sum() function. Running map() gives the following result:

>>> map(sum, list_one, list_two, list_three)
[33, 36, 39, 42, 45]

REMEMBER:
In Python 2 map(), will iterate (go through the elements of the lists) according to the longest list, and pass None to the function for the shorter lists, so your function should look for None and handle them, otherwise you will get errors. In Python 3 map() will stop after finishing with the shortest list. Also, in Python 3, map() returns an iterator, not a list.

set escape on
... node_name = 'Geometric Vectors \& Matrices' ...

or alternatively:

set define off
... node_name = 'Geometric Vectors & Matrices' ...

The first allows you to use the backslash to escape the &.

The second turns off & "globally" (no need to add a backslash anywhere). You can turn it on again by set define on and from that line on the ampersands will get their special meaning back, so you can turn it off for some parts of the script and not for others.

This might help you guys.(I've applied this to my Projects)

Here's the 3 easy steps.

1. Go to your Solution Explorer. Look for .edmx file (Usually found on root level)
2. Open that .edmx file, a Model Diagram window appears. Right click anywhere on that window and select "Update Model from Database". An Update Wizard window appears. Click Finish to update your model.
3. Save that .edmx file.

That's it. It will sync/refresh your Model base on the changes on your database.

For detailed instructions. Please visit the link below.

EF Database First with ASP.NET MVC: Changing the Database and updating its model.

You might also be interested in xsh. It features an interactive mode where you can do whatever you like with the document:

open 1.xml ;
ls //element/@id ;
for //p[@class="first"] echo text() ;

For just reading the last element of a slice:

sl[len(sl)-1]

For removing it:

sl = sl[:len(sl)-1]

Actually in Eclipse Indigo thru Oxygen, you have to go to the Types template Window -> Preferences -> Java -> Code Style -> Code templates -> (in right-hand pane) Comments -> double-click Types and make sure it has the following, which it should have by default:

/**
 * @author ${user}
 *
 * ${tags}
 */

and as far as I can tell, there is nothing in Eclipse to add the javadoc automatically to existing files in one batch. You could easily do it from the command line with sed & awk but that's another question.

If you are prepared to open each file individually, then selected the class / interface declaration line, e.g. public class AdamsClass { and then hit the key combo Shift + Alt + J and that will insert a new javadoc comment above, along with the author tag for your user. To experiment with other settings, go to Windows->Preferences->Java->Editor->Templates.
