Programs & Examples On #Command timeout

It was mentioned as a comment by @henri-chan, but I think it deserves some more attention:

When you update the content of an element with new html using jQuery/javascript, and this new html contains <script> tags, those are executed synchronously and thus triggering this error. Same goes for stylesheets.

You know this is happening when you see (multiple) scripts or stylesheets being loaded as XHR in the console window. (firefox).

margin: all_four_margin

by providing 50% to all_four_margin will place the element at the center

style="margin: 50%"

you can apply it for following too

margin: top right bottom left

margin: top right&left bottom

margin: top&bottom right&left

by giving appropriate % we get the element wherever we want.

File one:

angular.module('myApp.controllers', []);

File two:

angular.module('myApp.controllers').controller('Ctrl1', ['$scope', '$http', function($scope, $http){

}]);

File three:

angular.module('myApp.controllers').controller('Ctrl2', ['$scope', '$http', function($scope, $http){

}]);

Include in that order. I recommend 3 files so the module declaration is on its own.

As for folder structure there are many many many opinions on the subject, but these two are pretty good

I was facing same problem below is the solution that worked for me

First Go to Android SDK Manager then

select Tools then,

select Options

then check the box "Force https://... sources to be fetched using http://..."

hope it will help you also.

To print all the ascii values from 0 to 255 using while loop.

#include<stdio.h>

int main(void)
{
    int a;
    a = 0;
    while (a <= 255)
    {
        printf("%d = %c\n", a, a);
        a++;
    }
    return 0;
}

About int() and Swift 2.x: if you get a nil value after conversion check if you try to convert a string with a big number (for example: 1073741824), in this case try:

let bytesInternet : Int64 = Int64(bytesInternetString)!

def removeNonAscii(s): return "".join(filter(lambda x: ord(x)<128, s))

edit: my first impulse is always to use a filter, but the generator expression is more memory efficient (and shorter)...

def removeNonAscii(s): return "".join(i for i in s if ord(i)<128)

Keep in mind that this is guaranteed to work with UTF-8 encoding (because all bytes in multi-byte characters have the highest bit set to 1).

This will get you the PID of a process by name:

pidof name

Which you can then plug back in to ps for more detail:

ps -p $(pidof name)

According to MDN, <input type="search" /> is currently supported in all modern browsers:

<input type="search" value="Clear this." />

However, if you want different behavior that is consistent across browsers here are some light-weight alternatives that only require JavaScript:

Option 1 - Always display the 'x': (example here)

Array.prototype.forEach.call(document.querySelectorAll('.clearable-input>[data-clear-input]'), function(el) {
  el.addEventListener('click', function(e) {
    e.target.previousElementSibling.value = '';
  });
});

.clearable-input {
  position: relative;
  display: inline-block;
}
.clearable-input > input {
  padding-right: 1.4em;
}
.clearable-input > [data-clear-input] {
  position: absolute;
  top: 0;
  right: 0;
  font-weight: bold;
  font-size: 1.4em;
  padding: 0 0.2em;
  line-height: 1em;
  cursor: pointer;
}
.clearable-input > input::-ms-clear {
  display: none;
}

<p>Always display the 'x':</p>

<div class="clearable-input">
  <input type="text" />
  <span data-clear-input>&times;</span>
</div>

<div class="clearable-input">
  <input type="text" value="Clear this." />
  <span data-clear-input>&times;</span>
</div>

Option 2 - Only display the 'x' when hovering over the field: (example here)

Array.prototype.forEach.call(document.querySelectorAll('.clearable-input>[data-clear-input]'), function(el) {
  el.addEventListener('click', function(e) {
    e.target.previousElementSibling.value = '';
  });
});

.clearable-input {
  position: relative;
  display: inline-block;
}
.clearable-input > input {
  padding-right: 1.4em;
}
.clearable-input:hover > [data-clear-input] {
  display: block;
}
.clearable-input > [data-clear-input] {
  display: none;
  position: absolute;
  top: 0;
  right: 0;
  font-weight: bold;
  font-size: 1.4em;
  padding: 0 0.2em;
  line-height: 1em;
  cursor: pointer;
}
.clearable-input > input::-ms-clear {
  display: none;
}

<p>Only display the 'x' when hovering over the field:</p>

<div class="clearable-input">
  <input type="text" />
  <span data-clear-input>&times;</span>
</div>

<div class="clearable-input">
  <input type="text" value="Clear this." />
  <span data-clear-input>&times;</span>
</div>

Option 3 - Only display the 'x' if the input element has a value: (example here)

Array.prototype.forEach.call(document.querySelectorAll('.clearable-input'), function(el) {
  var input = el.querySelector('input');

  conditionallyHideClearIcon();
  input.addEventListener('input', conditionallyHideClearIcon);
  el.querySelector('[data-clear-input]').addEventListener('click', function(e) {
    input.value = '';
    conditionallyHideClearIcon();
  });

  function conditionallyHideClearIcon(e) {
    var target = (e && e.target) || input;
    target.nextElementSibling.style.display = target.value ? 'block' : 'none';
  }
});

.clearable-input {
  position: relative;
  display: inline-block;
}
.clearable-input > input {
  padding-right: 1.4em;
}
.clearable-input >[data-clear-input] {
  display: none;
  position: absolute;
  top: 0;
  right: 0;
  font-weight: bold;
  font-size: 1.4em;
  padding: 0 0.2em;
  line-height: 1em;
  cursor: pointer;
}
.clearable-input > input::-ms-clear {
  display: none;
}

<p>Only display the 'x' if the `input` element has a value:</p>

<div class="clearable-input">
  <input type="text" />
  <span data-clear-input>&times;</span>
</div>

<div class="clearable-input">
  <input type="text" value="Clear this." />
  <span data-clear-input>&times;</span>
</div>

Took me a while to find this out but if you a number stored in a variable, say x and you want to select it, use

document.querySelector('a[data-a= + CSS.escape(x) + ']'). 

This is due to some attribute naming specifications that I'm not yet very familiar with. Hope this will help someone.

For the people who want to use the JSON.parse(JSON.stringify(obj)) version, but without losing the Date objects, you can use the second argument of parse method to convert the strings back to Date:

function clone(obj) {
  var regExp = /^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}\.\d{3}Z$/;
  return JSON.parse(JSON.stringify(obj), function(k, v) {
    if (typeof v === 'string' && regExp.test(v))
      return new Date(v)
    return v;
  })
}

// usage:
var original = {
 a: [1, null, undefined, 0, {a:null}, new Date()],
 b: {
   c(){ return 0 }
 }
}

var cloned = clone(original)

console.log(cloned)

Method 1

You should not make an ajax call, just put the src of the img element as the url of the image.

This would be useful if you use GET instead of POST

<script type="text/javascript" > 

  $(document).ready( function() { 
      $('.div_imagetranscrits').html('<img src="get_image_probes_via_ajax.pl?id_project=xxx" />')
  } );

</script>

Method 2

If you want to POST to that image and do it the way you do (trying to parse the contents of the image on the client side, you could try something like this: http://en.wikipedia.org/wiki/Data_URI_scheme

You'll need to encode the data to base64, then you could put data:[<MIME-type>][;charset=<encoding>][;base64],<data> into the img src

as example:

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot img" />

To encode to base64:

• in plain javascript, see How can you encode a string to Base64 in JavaScript?
• in perl http://perldoc.perl.org/MIME/Base64.html
• in php http://php.net/manual/en/function.base64-encode.php

This is the problem

double a[] = null;

Since a is null, NullPointerException will arise every time you use it until you initialize it. So this:

a[i] = var;

will fail.

A possible solution would be initialize it when declaring it:

double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7

IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.

java.lang.NullPointerException

This exception means there's a variable with null value being used. How to solve? Just make sure the variable is not null before being used.

at twoten.TwoTenB.(TwoTenB.java:29)

This line has two parts:

• First, shows the class and method where the error was thrown. In this case, it was at <init> method in class TwoTenB declared in package twoten. When you encounter an error message with SomeClassName.<init>, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).
• Secondly, shows the file and line number location where the error is thrown, which is between parenthesis. This way is easier to spot where the error arose. So you have to look into file TwoTenB.java, line number 29. This seems to be a[i] = var;.

From this line, other lines will be similar to tell you where the error arose. So when reading this:

at javapractice.JavaPractice.main(JavaPractice.java:32)

It means that you were trying to instantiate a TwoTenB object reference inside the main method of your class JavaPractice declared in javapractice package.

Here we go

    StringBuilder stringBuilder = new StringBuilder();
    for (int i = 0; i < array.length; i++) {

Through the Javascript SDK (v2.12 - April, 2017) you can get the details of the picture request this way:

FB.api("/" + uid + "/picture?redirect=0", function (response) {
  console.log(response);

  // prints the following:
  //data: {
  //  height: 50
  //  is_silhouette: false
  //  url: "https://lookaside.facebook.com/platform/profilepic/?asid=…&height=50&width=50&ext=…&hash…"
  //  width: 50
  //}

  if (response && !response.error) {
    // change the src attribute of img elements
    [...document.getElementsByClassName('fb-user-img')].forEach(
      i => i.src = response.data.url
    );

    // OR redirect to the URL above
    location.assign(response.data.url);
  }
});

For getting the JSON response the parameter redirect with 0 (zero) as value is important since the request redirects to the image by default. You may still add other parameters in the same URL. Examples:

• "/" + uid + "/picture?redirect=0&width=100&height=100": a 100x100 image will be returned;
• "/" + uid + "/picture?redirect=0&type=large": a 200x200 image is returned. Other possible type values include: small, normal, album, and square.

Remove warnings.filterwarnings and add:

numpy.seterr(all='raise')

Note that numeric objects in R are stored with double precision, which gives you (roughly) 16 decimal digits of precision - the rest will be noise. I grant that the number shown above is probably just for an example, but it is 22 digits long.

To use it in phtml apply :

echo $this->getSkinUrl('your_image_folder_under_skin/image_name.png');

To use skin path in cms page :

<img style="width: 715px; height: 266px;" src="{{skin url=images/banner1.jpg}}" alt="title" />

This part====> {{skin url=images/banner1.jpg}}

I hope this will help you.

var lbltext = document.getElementById('*spaM4').innerHTML

It can be much simpler than what you are doing.

HTML:

<input id="myField" type="text" name="email"/>

JavaScript:

// getting the value
var email = $("#myField").val();

// setting the value
$("#myField").val( "new value here" );

It is possible to reference an intellij 'Path Variable' in an intellij 'Run Configuration'.

In 'Path Variables' create a variable for example ANALYTICS_VERSION.

In a 'Run Configuration' under 'Environment Variables' add for example the following:

ANALYTICS_LOAD_LOCATION=$MAVEN_REPOSITORY$\com\my\company\analytics\$ANALYTICS_VERSION$\bin

To answer the original question you would need to add an APP_HOME environment variable to your run configuration which references the path variable:

APP_HOME=$APP_HOME$

advance code for the search for all attributes of the object in arrays

b=[]; 
yourArray.forEach(x => {
      Object.keys(x).forEach(i => {if (x[i].match('5') && !b.filter(y => y === x).length) { b.push(x) }})
    });
console.log(b)

The CSS :active state means the active state of the clicked link - the moment when you clicked on it, but not released the mouse button yet, for example. It doesn't know which page you're on and can't apply any styles to the menu items.

To fix your problem you have to create a class and add it manually to the current page's menu:

a.active { color: #f00 }

<ul>
    <li><a href="index.php" class="active">HOME</a></li>
    <li><a href="two.php">PORTFOLIO</a></li>
    <li><a href="three.php">ABOUT</a></li>
    <li><a href="four.php">CONTACT</a></li>
    <li><a href="five.php">SHOP</a></li>
</ul>

I have an extension method:

public static string GetIp(this HttpContextBase context)
{
    if (context == null || context.Request == null)
        return string.Empty;

    return context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] 
           ?? context.Request.UserHostAddress;
}

Note: "HTTP_X_FORWARDED_FOR" is for ip behind proxy. context.Request.UserHostAddress is identical to "REMOTE_ADDR".

But bear in mind it is not necessary the actual IP though.

You may use this command for listing the files for your own debuggable apk:

adb shell run-as com.corp.appName ls /data/data/com.corp.appName/cache

And this script for pulling from cache:

#!/bin/sh
adb shell "run-as com.corp.appName cat '/data/data/com.corp.appNamepp/$1' > '/sdcard/$1'"
adb pull "/sdcard/$1"
adb shell "rm '/sdcard/$1'"

Then you can pull a file from cache like this:

./pull.sh cache/someCachedData.txt

Root is not required.

If you have compatibility with Object.keys, and node does have compatibility, you should use that for sure.

However, if you do not have compatibility, and for any reason using a loop function is out of the question - like me, I used the following solution:

JSON.stringify(obj) === '{}'

Consider this solution a 'last resort' use only if must.

See in the comments "there are many ways in which this solution is not ideal".

I had a last resort scenario, and it worked perfectly.

According to the Cloudera documentation - What's New in CDH 5.7.0 it includes Spark 1.6.0.

figlegend may be what you're looking for: http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.figlegend

Example here: http://matplotlib.org/examples/pylab_examples/figlegend_demo.html

Another example:

plt.figlegend( lines, labels, loc = 'lower center', ncol=5, labelspacing=0. )

or:

fig.legend( lines, labels, loc = (0.5, 0), ncol=5 )

let urlString = baseURL + currency

    if let url = URL(string: urlString){
        let session = URLSession(configuration: .default)        
        let task = session.dataTask(with: url){ (data, reponse, error) in
            if error != nil{
                print(error)
                return
            }


            let dataString = String(data: data!, encoding: .utf8)
            print(dataString)

        }

        task.resume()

    }

I try in this example to show you a complete example to personalize your OrderBy sorts

 import java.util.List;
 import org.springframework.data.domain.Page;
 import org.springframework.data.domain.Sort;
 import org.springframework.data.jpa.repository.*;
 import org.springframework.data.repository.query.Param;
 import org.springframework.stereotype.Repository;
 import org.springframework.data.domain.Sort;
 /**
 * Spring Data  repository for the User entity.
 */
 @SuppressWarnings("unused")
 @Repository
 public interface UserRepository extends JpaRepository<User, Long> {
 List <User> findAllWithCustomOrderBy(Sort sort);
 }

you will use this example : A method for build dynamically a object that instance of Sort :

import org.springframework.data.domain.Sort;
public class SampleOrderBySpring{
 Sort dynamicOrderBySort = createSort();
     public static void main( String[] args )
     {
       System.out.println("default sort \"firstName\",\"name\",\"age\",\"size\" ");
       Sort defaultSort = createStaticSort();
       System.out.println(userRepository.findAllWithCustomOrderBy(defaultSort ));


       String[] orderBySortedArray = {"name", "firstName"};
       System.out.println("default sort ,\"name\",\"firstName\" ");
       Sort dynamicSort = createDynamicSort(orderBySortedArray );
       System.out.println(userRepository.findAllWithCustomOrderBy(dynamicSort ));
      }
      public Sort createDynamicSort(String[] arrayOrdre) {
        return  Sort.by(arrayOrdre);
        }

   public Sort createStaticSort() {
        String[] arrayOrdre  ={"firstName","name","age","size");
        return  Sort.by(arrayOrdre);
        }
}

It may be curable by increasing the stack size - but a better solution would be to work out how to avoid recursing so much. A recursive solution can always be converted to an iterative solution - which will make your code scale to larger inputs much more cleanly. Otherwise you'll really be guessing at how much stack to provide, which may not even be obvious from the input.

Are you absolutely sure it's failing due to the size of the input rather than a bug in the code, by the way? Just how deep is this recursion?

EDIT: Okay, having seen the update, I would personally try to rewrite it to avoid using recursion. Generally having a Stack<T> of "things still do to" is a good starting point to remove recursion.

This is a bit of a work around, but one way you can achieve this is by adding a breakpoint at the start of the javascript file or block you want to manipulate.

Then when you reload, the debugger will pause on that breakpoint, and you can make any changes you want to the source, save the file and then run the debugger through the modified code.

But as everyone has said, next reload the changes will be gone - at least it let's you run some slightly modified JS client side.

keytool -exportcert -alias androiddebugkey -keystore       C:\Users\pravin\.android\debug.keystore | "H:\OpenSSL\bin\openssl" sha1 -binary | "H:\OpenSSL\bin\openssl" base64

This worked for me ...

Steps:

1) Open command line go to - > java Keytool..... for me C:\Program Files\Java\JDK1.7\bin
2) Download OpenSSL from google
3) paste this with changing your paths -
   keytool -exportcert -alias androiddebugkey -keystore C:\Users\pravin\.android\debug.keystore | "H:\OpenSSL\bin\openssl" sha1 -binary | "H:\OpenSSL\bin\openssl" base64 

    ....................   give proper debug.keystore path and openSSL path .. 

4) Finley it may be ask u password .. so give password -> android   ...
5) you will get 28 characters that will be your has key

ooh! neat question.

Matlab's for loop takes a matrix as input and iterates over its columns. Matlab also handles practically everything by value (no pass-by-reference) so I would expect that it takes a snapshot of the for-loop's input so it's immutable.

here's an example which may help illustrate:

>> A = zeros(4); A(:) = 1:16

A =

     1     5     9    13
     2     6    10    14
     3     7    11    15
     4     8    12    16

>> i = 1; for col = A; disp(col'); A(:,i) = i; i = i + 1; end;
     1     2     3     4

     5     6     7     8

     9    10    11    12

    13    14    15    16

>> A

A =

     1     2     3     4
     1     2     3     4
     1     2     3     4
     1     2     3     4

If you want to get the number of lines from a certain author, try the following code:

git ls-files "*.java" | xargs -I{} git blame {} | grep ${your_name} | wc -l

A simple: $sth->finish(); Would probably save you from worrying about this. Mysql uses the system's tmp space instead of it's own space.

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

If you need some advanced explanation you need read both specifications :

https://oauth.net/core/1.0a/

https://oauth.net/2/

If you need a clear explanation of flow differences , this could be help you:

OAuth 1.0 Flow

1. Client application registers with provider, such as Twitter.
2. Twitter provides client with a “consumer secret” unique to that application.
3. Client app signs all OAuth requests to Twitter with its unique “consumer secret.”
4. If any of the OAuth request is malformed, missing data, or signed improperly, the request will be rejected.

OAuth 2.0 Flow

1. Client application registers with provider, such as Twitter.
2. Twitter provides client with a “client secret” unique to that application.
3. Client application includes “client secret” with every request commonly as http header.
4. If any of the OAuth request is malformed, missing data, or contains the wrong secret, the request will be rejected.

Yes, you're right. With the css() method you can retrieve the desired css value stored in the DOM. You can read more about this at: http://api.jquery.com/css/

But if you want to get its position you can check offset() and position() methods to get it's position.

my good friend Alessandro have a nice post regarding bit operators in C#, you should read about it so you know what to do.

It's pretty easy. If you break down the IP given to you to binary, the network address is the ip address where all of the host bits (the 0's in the subnet mask) are 0,and the last address, the broadcast address, is where all the host bits are 1.

For example:

ip 192.168.33.72 mask 255.255.255.192

11111111.11111111.11111111.11000000 (subnet mask)
11000000.10101000.00100001.01001000 (ip address)

The bolded parts is the HOST bits (the rest are network bits). If you turn all the host bits to 0 on the IP, you get the first possible IP:

11000000.10101000.00100001.01000000 (192.168.33.64)

If you turn all the host bits to 1's, then you get the last possible IP (aka the broadcast address):

11000000.10101000.00100001.01111111 (192.168.33.127)

So for my example:

the network is "192.168.33.64/26":
Network address: 192.168.33.64
First usable: 192.168.33.65 (you can use the network address, but generally this is considered bad practice)
Last useable: 192.168.33.126
Broadcast address: 192.168.33.127

For pausing multiple videos I have found that this works nicely:

$("video").each(function(){
    $(this).get(0).pause();
});

This can be put into a click function which is quite handy.

Assuming that you've written an equals method for Dog correctly that compares based on the id of the Dog the easiest and simplest way to return an item in the list is as follows.

if (dogList.contains(dog)) {
   return dogList.get(dogList.indexOf(dog));
}

That's less performance intensive that other approaches here. You don't need a loop at all in this case. Hope this helps.

P.S You can use Apache Commons Lang to write a simple equals method for Dog as follows:

@Override
public boolean equals(Object obj) {     
   EqualsBuilder builder = new EqualsBuilder().append(this.getId(), obj.getId());               
   return builder.isEquals();
}

Sessions are stored on the server and are set from server side code, not client side code such as JavaScript.

What you want is a cookie, someone's given a brilliant explanation in this Stack Overflow question here: How do I set/unset cookie with jQuery?

You could potentially use sessions and set/retrieve them with jQuery and AJAX, but it's complete overkill if Cookies will do the trick.

So if want to set the value of an environment variable to something different for every build then we can pass these values during build time and we don't need to change our docker file every time.

While ENV, once set cannot be overwritten through command line values. So, if we want to have our environment variable to have different values for different builds then we could use ARG and set default values in our docker file. And when we want to overwrite these values then we can do so using --build-args at every build without changing our docker file.

For more details, you can refer this.

First of all, Relax.

"Nothing is under our control. Our control is mere illusion.", "To err is human"

I get that you've unintentionally pushed your code to remote-master. THIS is going to be alright.

1. At first, get the SHA-1 value of the commit you are trying to return, e.g. commit to master branch. run this:

git log

you'll see bunch of 'f650a9e398ad9ca606b25513bd4af9fe...' like strings along with each of the commits. copy that number from the commit that you want to return back.

2. Now, type in below command:

git reset --hard your_that_copied_string_but_without_quote_mark

you should see message like "HEAD is now at ". you are on clear. What it just have done is to reflect that change locally.

3. Now, type in below command:

git push -f

you should see like

"warning: push.default is unset; its implicit value has changed in..... ... Total 0 (delta 0), reused 0 (delta 0) ... ...your_branch_name -> master (forced update)."

Now, you are all clear. Check the master with "git log" again, your fixed_destination_commit should be on top of the list.

You are welcome (in advance ;))

UPDATE:

Now, the changes you had made before all these began, are now gone. If you want to bring those hard-works back again, it's possible. Thanks to git reflog, and git cherry-pick commands.

For that, i would suggest to please follow this blog or this post.

The accepted answer here is a bit dated. As of April 2020, a recommended approach seen on the MDN website suggests using FormData and also does not ask to set the content type. https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch

I'm quoting the code snippet for convenience:

const formData = new FormData();
const fileField = document.querySelector('input[type="file"]');

formData.append('username', 'abc123');
formData.append('avatar', fileField.files[0]);

fetch('https://example.com/profile/avatar', {
  method: 'PUT',
  body: formData
})
.then((response) => response.json())
.then((result) => {
  console.log('Success:', result);
})
.catch((error) => {
  console.error('Error:', error);
});

For things like numbers (decimal points, commas in amounts), they are usually preferred in the specific culture.

A appropriate way to do this would be set it at the culture level (for German) like this:

Thread.CurrentThread.CurrentCulture.NumberFormat = new CultureInfo("de").NumberFormat;

Insertion sort with the following behavior:

1. For each element k in slots 1..n, first check whether el[k] >= el[k-1]. If so, go to next element. (Obviously skip the first element.)
2. If not, use binary-search in elements 1..k-1 to determine the insertion location, then scoot the elements over. (You might do this only if k>T where T is some threshold value; with small k this is overkill.)

This method makes the least number of comparisons.

This should not affect everyone, but one of the semi-hidden reasons of the repository size being large could be Git submodules.

You might have added one or more submodules, but stopped using it at some time, and some files remained in .git/modules directory. To make redundant submodule files gone away, see this question.

However, just like the main repository, the other way is to navigate to the submodule directory in .git/modules, and do a, for example, git gc --aggressive --prune.

These should have a good impact in the repository size, but as long as you use Git submodules, e.g. especially with large libraries, your repository size should not change drastically.

if you add a jpg,png,pdf picture, you should use pdflatex to compile it.

The code works for me. (after adding missing except clause / import statements)

Did you put \ in the original code?

urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' \
              + stock + '/chartdata;type=quote;range=5d/csv'

If you omit it, it could be a cause of the exception:

>>> stock = 'GOOG'
>>> urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/'
>>> + stock + '/chartdata;type=quote;range=5d/csv'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary +: 'str'

BTW, string(e) should be str(e).

You can use the HTML tag in order to apply font size, font color in one line on JavaScript, as well as you can use .fontcolor() method to define color, .fontsize() method to define the font size, .bold() method to define bold, etc. These are called JavaScript Built-in Functions.

• Here is a list of some JavaScript built-in functions:

  .big()
  .small()
  .italics()
  .fixed()
  .strike()
  .sup()

• The below built-in functions require parameters:

  .fontsize() //e.g.: the size to be applied in number .fontsize(4)

  .fontcolor("") //e.g.: the color to be applied in string .fontcolor("red")

  .txt.link("") //e.g.: the url to be linkable as string .link("www.test.com")

  .toUpperCase() //e.g.: the converted to uppercase to be applied in string .toUpperCase()

• Remember the syntax is: string.functionName() e.g.:

  var txt = "Hello World!"; txt.bold();

• This also can be done in one line:

  var txt = "Hello World!".bold();

  The result will be: Hello World!

• You can use multiple built-in functions in one line, adding one next to the other. e.g.:

  "10/22/2018".fontcolor("red").fontsize(4).bold()

• The following is an example how I used it on my JavaScript code to change font (color, size, bold) using both HTML tags and JavaScript functions:

vForm.message = "<HTML><font size = 4 color = 'red'><b> Application Deadline was </b></font></HTML> " + "10/22/2018".fontcolor("red").fontsize(4).bold(); /* setting HTML font color, size, bold and combined them with JavaScript functions to change font color, size, bold in JavaScript code */

• Here is the result:

You can also try to get the column names from panda data frame that returns columnn name as well dtype. here i'll read csv file from https://mlearn.ics.uci.edu/databases/autos/imports-85.data but you have define header that contain columns names.

import pandas as pd

url="https://mlearn.ics.uci.edu/databases/autos/imports-85.data"

df=pd.read_csv(url,header = None)

headers=["symboling","normalized-losses","make","fuel-type","aspiration","num-of-doors","body-style",
         "drive-wheels","engine-location","wheel-base","length","width","height","curb-weight","engine-type",
         "num-of-cylinders","engine-size","fuel-system","bore","stroke","compression-ratio","horsepower","peak-rpm"
         ,"city-mpg","highway-mpg","price"]

df.columns=headers

print df.columns

Here is another way to find out apps package name and launcher activity.

Step1: Start "adb logcat" in command prompt.

Step2: Open the app (either in emulator or real device)

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

VIDEO_ID with actual ID of your YouTube video.

<div data-video="VIDEO_ID"  
        data-autoplay="0"         
        data-loop="1"             
        id="youtube-audio">
 </div>

You could add a method to String to make it more semantic:

String.metaClass.getNotBlank = { !delegate.allWhitespace }

which let's you do:

groovy:000> foo = ''
===> 
groovy:000> foo.notBlank
===> false
groovy:000> foo = 'foo'
===> foo
groovy:000> foo.notBlank
===> true

For people that come here that are just trying to get the repository but don't care about the protocol (ssh / https), you might just want to use https instead of ssh (if it's supported).

So for example you use

git clone https://github.com/%REPOSITORYFOLDER%/%REPOSITORYNAME%.git

instead of

git clone [email protected]:%REPOSITORYFOLDER%/%REPOSITORYNAME%.git

I'm surprised there is not some single formatter that returns a default (and safe) 'for appending in filename' - format of the time, We could simply write FD.write('mybackup'+time.strftime('%(formatter here)') + 'ext'

"%x" instead of "%Y%m%d-%H%M%S"

var result = list.GroupBy(x => x.Category).Select(x => x.First())

This problem can be caused by requests for certain files that don't exist. For example, requests for files in wp-content/uploads/ where the file does not exist.

If this is the situation you're seeing, you can solve the problem by going to .htaccess and changing this line:

RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

to:

RewriteRule ^(wp-(content|admin|includes).*) - [L]

The underlying issue is that the rule above triggers a rewrite to the exact same url with a slash in front and because there was a rewrite, the newly rewritten request goes back through the rules again and the same rule is triggered. By changing that line's "$1" to "-", no rewrite happens and so the rewriting process does not start over again with the same URL.

It's possible that there's a difference in how apache 2.2 and 2.4 handle this situation of only-difference-is-a-slash-in-front and that's why the default rules provided by WordPress aren't working perfectly.

As pointed out by @Christian, best to try operation first then login only if necessary. Problem is that "if necessary" is not that obvious to do robustly. One approach is to compare the stderr of the docker operation with some strings that are known (by trial and error). For example,

try "docker OPERATION"
if it failed: 
    capture the stderr of "docker OPERATION"
    if it ends with "no basic auth credentials": 
        try docker login
    else if it ends with "not found":
        fatal error: image name/tag probably incorrect
    else if it ends with <other stuff you care to trap>:
        ...
    else:
        fatal error: unknown cause

try docker OPERATION again
if this fails: you're SOL!

give this a try,

insert into tableName (ImageColumn) 
SELECT BulkColumn 
FROM Openrowset( Bulk 'image..Path..here', Single_Blob) as img

INSERTING

REFRESHING THE TABLE

Developer point of view
If you are in development mode (like in the original question), the best approach is to disable caching in the browser via HTML meta tags. To make this approach universal you must insert at least three meta tags as shown below.

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="0" />

In this way, you as a developer, only need to refresh the page to see the changes. But do not forget to comment that code when in production, after all caching is a good thing for your clients.

Production Mode
Because in production you will allow caching and your clients do not need to know how to force a full reload or any other trick, you must warranty the browser will load the new file. And yes, in this case, the best approach I know is to change the name of the file.

On Ubuntu, hostname command can be used with the following options:

• -i, --ip-address addresses for the host name
• -I, --all-ip-addresses all addresses for the host

For example:

$ hostname -i
172.17.0.2

To assign to the variable, the following one-liner can be used:

IP=$(hostname -i)

In you case here, if you want to right-align that green button, just change the one div to have everything right-aligned:

<div class="action_buttons_header" style="text-align: right;">

The div is already taking up the full width of that section, so just shift the green button the right by right-aligning the text.

Requests doesn't have an equivalent to Urlib2's read().

>>> import requests
>>> response = requests.get("http://www.google.com")
>>> print response.content
'<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage"><head>....'
>>> print response.content == response.text
True

It looks like the POST request you are making is returning no content. Which is often the case with a POST request. Perhaps it set a cookie? The status code is telling you that the POST succeeded after all.

Edit for Python 3:

Python now handles data types differently. response.content returns a sequence of bytes (integers that represent ASCII) while response.text is a string (sequence of chars).

Thus,

>>> print response.content == response.text
False

>>> print str(response.content) == response.text
True

To summarize a few items here: There are some pixel-by-pixel options that, while being simple just aren't fast.

@Luis' comment linking to: (archived) https://web.archive.org/web/20110827032809/http://www.switchonthecode.com/tutorials/csharp-tutorial-convert-a-color-image-to-grayscale is superb.

He runs through three different options and includes timings for each.

Choose Open Transcript from the ... dropdown to the right of the vote up/down and share links.

This will open a Transcript scrolling div on the right side.

You can then use Copy. Note that you cannot use Select All but need to click the top line, then scroll to the bottom using the scroll thumb, and then shift-click on the last line.

Note that you can also search within this text using the normal web page search.

If the file input name indicates an array and flags multiple, and you parse the entire form with FormData, it is not necessary to iteratively append() the input files. FormData will automatically handle multiple files.

$('#submit_1').on('click', function() {_x000D_
  let data = new FormData($("#my_form")[0]);_x000D_
_x000D_
  $.ajax({_x000D_
    url: '/path/to/php_file',_x000D_
    type: 'POST',_x000D_
    data: data,_x000D_
    processData: false,_x000D_
    contentType: false,_x000D_
    success: function(r) {_x000D_
      console.log('success', r);_x000D_
    },_x000D_
    error: function(r) {_x000D_
      console.log('error', r);_x000D_
    }_x000D_
  });_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<form id="my_form">_x000D_
  <input type="file" name="multi_img_file[]" id="multi_img_file" accept=".gif,.jpg,.jpeg,.png,.svg" multiple="multiple" />_x000D_
  <button type="button" name="submit_1" id="submit_1">Not type='submit'</button>_x000D_
</form>

Note that a regular button type="button" is used, not type="submit". This shows there is no dependency on using submit to get this functionality.

The resulting $_FILES entry is like this in Chrome dev tools:

multi_img_file:
  error: (2) [0, 0]
  name: (2) ["pic1.jpg", "pic2.jpg"]
  size: (2) [1978036, 2446180]
  tmp_name: (2) ["/tmp/phphnrdPz", "/tmp/phpBrGSZN"]
  type: (2) ["image/jpeg", "image/jpeg"]

Note: There are cases where some images will upload just fine when uploaded as a single file, but they will fail when uploaded in a set of multiple files. The symptom is that PHP reports empty $_POST and $_FILES without AJAX throwing any errors. Issue occurs with Chrome 75.0.3770.100 and PHP 7.0. Only seems to happen with 1 out of several dozen images in my test set.

Check out the sass-globbing project.

I encountered the same issue when calling super.onCreate() at the end of my method. The reason: attachActivity() is called in onCreate() of FragmentActivity. When overriding onCreate() and, for example, creating tabs, the Tab manager will try to switch to a fragment while not having the activity attached to the FragmentManager.

Simple solution: Move the call to super.onCreate() to the head of the function body.

In general, it seems there are loads of reasons this issue may occur. This is just another one ...

In this code you are not comparing string values, you are comparing pointer values. If you want to compare string values you need to use a string comparison function such as strcmp.

if ( 0 == strcmp(var1, "dev")) {
  ..
}

An alternative method to BenAlabaster answer

First of all, you can rewrite the query like this:

var matches = from Users in people
        where Users.User_Rights == "Admin" ||
              Users.User_Rights == "Users" || 
              Users.User_Rights == "Limited"
        select Users;

Certainly this is more 'wordy' and a pain to write but it works all the same.

So if we had some utility method that made it easy to create these kind of LINQ expressions we'd be in business.

with a utility method in place you can write something like this:

var matches = ctx.People.Where(
        BuildOrExpression<People, string>(
           p => p.User_Rights, names
        )
);

This builds an expression that has the same effect as:

var matches = from p in ctx.People
        where names.Contains(p.User_Rights)
        select p;

But which more importantly actually works against .NET 3.5 SP1.

Here is the plumbing function that makes this possible:

public static Expression<Func<TElement, bool>> BuildOrExpression<TElement, TValue>(
        Expression<Func<TElement, TValue>> valueSelector, 
        IEnumerable<TValue> values
    )
{     
    if (null == valueSelector) 
        throw new ArgumentNullException("valueSelector");

    if (null == values)
        throw new ArgumentNullException("values");  

    ParameterExpression p = valueSelector.Parameters.Single();

    if (!values.Any())   
        return e => false;

    var equals = values.Select(value =>
        (Expression)Expression.Equal(
             valueSelector.Body,
             Expression.Constant(
                 value,
                 typeof(TValue)
             )
        )
    );
   var body = equals.Aggregate<Expression>(
            (accumulate, equal) => Expression.Or(accumulate, equal)
    ); 

   return Expression.Lambda<Func<TElement, bool>>(body, p);
}

I'm not going to try to explain this method, other than to say it essentially builds a predicate expression for all the values using the valueSelector (i.e. p => p.User_Rights) and ORs those predicates together to create an expression for the complete predicate

(note: this is answer to original version of the question, which did not have requirements for "default")

You can ask it to be pretty.

db.collection.find().pretty()

From (An Unofficial) Python Reference Wiki:

The public names defined by a module are determined by checking the module's namespace for a variable named __all__; if defined, it must be a sequence of strings which are names defined or imported by that module. The names given in __all__ are all considered public and are required to exist. If __all__ is not defined, the set of public names includes all names found in the module's namespace which do not begin with an underscore character ("_"). __all__ should contain the entire public API. It is intended to avoid accidentally exporting items that are not part of the API (such as library modules which were imported and used within the module).

the simple way is curl (and FASTER too)

<?php
$mylinks="http://site.com/page.html";
$handlerr = curl_init($mylinks);
curl_setopt($handlerr,  CURLOPT_RETURNTRANSFER, TRUE);
$resp = curl_exec($handlerr);
$ht = curl_getinfo($handlerr, CURLINFO_HTTP_CODE);


if ($ht == '404')
     { echo 'OK';}
else { echo 'NO';}

?>

Please have a look at http://jsfiddle.net/2dJAN/59/

$("#submit").click(function () {
var url = $(location).attr('href');
$('#spn_url').html('<strong>' + url + '</strong>');
});

• In HTML 4, <foo / (yes, with no > at all) means <foo> (which leads to <br /> meaning <br>> (i.e. <br>&gt;) and <title/hello/ meaning <title>hello</title>). This is an SGML rule that browsers did a very poor job of supporting, and the spec advises authors to avoid the syntax.

• In XHTML, <foo /> means <foo></foo>. This is an XML rule that applies to all XML documents. That said, XHTML is often served as text/html which (historically at least) gets processed by browsers using a different parser than documents served as application/xhtml+xml. The W3C provides compatibility guidelines to follow for XHTML as text/html. (Essentially: Only use self-closing tag syntax when the element is defined as EMPTY (and the end tag was forbidden in the HTML spec)).

• In HTML5, the meaning of <foo /> depends on the type of element.

  • On HTML elements that are designated as void elements (essentially "An element that existed before HTML5 and which was forbidden to have any content"), end tags are simply forbidden. The slash at the end of the start tag is allowed, but has no meaning. It is just syntactic sugar for people (and syntax highlighters) that are addicted to XML.
  • On other HTML elements, the slash is an error, but error recovery will cause browsers to ignore it and treat the tag as a regular start tag. This will usually end up with a missing end tag causing subsequent elements to be children instead of siblings.
  • Foreign elements (imported from XML applications such as SVG) treat it as self-closing syntax.

Check this out:

SELECT
  p.Person,
  p.`Group`,
  p.Age
FROM
  people p
  INNER JOIN
  (
    SELECT MAX(Age) AS Age, `Group` FROM people GROUP BY `Group`
    UNION
    SELECT MAX(p3.Age) AS Age, p3.`Group` FROM people p3 INNER JOIN (SELECT MAX(Age) AS Age, `Group` FROM people GROUP BY `Group`) p4 ON p3.Age < p4.Age AND p3.`Group` = p4.`Group` GROUP BY `Group`
  ) p2 ON p.Age = p2.Age AND p.`Group` = p2.`Group`
ORDER BY
  `Group`,
  Age DESC,
  Person;

I like to do the following if running in a script where the function is defined:

POINTER= # used for function return values

my_function() {
    # do stuff
    POINTER="my_function_return"
}

my_other_function() {
    # do stuff
    POINTER="my_other_function_return"
}

my_function
RESULT="$POINTER"

my_other_function
RESULT="$POINTER"

I like this, becase I can then include echo statements in my functions if I want

my_function() {
    echo "-> my_function()"
    # do stuff
    POINTER="my_function_return"
    echo "<- my_function. $POINTER"
}

To expand upon Mr. Eels comment, you can do it like this:

    File file = new File("C:\\A.txt");
    FileWriter writer;
    try {
        writer = new FileWriter(file, true);
        PrintWriter printer = new PrintWriter(writer);
        printer.append("Sue");
        printer.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Don't say we ain't good to ya!

For those that pointed out the fact that you can't use the toString method of InputStream like this see https://stackoverflow.com/a/5445161/1304830 :

My correct answer would be then :

import org.json.JSONObject;

public static String convertStreamToString(java.io.InputStream is) {
    java.util.Scanner s = new java.util.Scanner(is).useDelimiter("\\A");
    return s.hasNext() ? s.next() : "";
}

...

JSONObject json = new JSONObject(convertStreamToString(url.openStream());

You can disable need to run Internet Explorer's first launch configuration by running this PowerShell script, it will adjust corresponding registry property:

Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Internet Explorer\Main" -Name "DisableFirstRunCustomize" -Value 2

After this, WebClient will work without problems

You either haven't selected a CPU/ABI target in the dropdown below the target, or you haven't installed a system image. Open your SDK manager and ensure that you've installed ARM EABI v7a System Image under the Android 4.2 section.

This is more the Angular way to do it: http://plnkr.co/edit/xYNX47EsYvl4aRuGZmvo?p=preview

1. I added $scope.selectedItem that gets you past your first problem (defaulting the image)
2. I added $scope.setSelectedItem and called it in ng-click. Your final requirements may be different, but using a directive to bind click and change src was overkill, since most of it can be handled with template
3. Notice use of ngSrc to avoid errant server calls on initial load
4. You'll need to adjust some styles to get the image positioned right in the div. If you really need to use background-image, then you'll need a directive like ngSrc that defers setting the background-image style until after real data has loaded.

Try this

 <allow  users="?" />

Now you are using <deny users="?" /> that means you are not allowing authenticated user to use your site.

authorization Element

you have to change permission on the mentioned path.

Format in other syntax is possible in this way

[DateTime]::Today.AddDays(-1).ToString("yyyyMMdd")

Use a BackgroundWorker. It will allow you to get callbacks on completion and allow you to track progress. You can set the Result value on the event arguments to the resulting value.

    public void UseBackgroundWorker()
    {
        var worker = new BackgroundWorker();
        worker.DoWork += DoWork;
        worker.RunWorkerCompleted += WorkDone;
        worker.RunWorkerAsync("input");
    }

    public void DoWork(object sender, DoWorkEventArgs e)
    {
        e.Result = e.Argument.Equals("input");
        Thread.Sleep(1000);
    }

    public void WorkDone(object sender, RunWorkerCompletedEventArgs e)
    {
        var result = (bool) e.Result;
    }

npx should come with npm 5.2+, and you have node 5.6 .. I found that when I install node using nvm for Windows, it doesn't download npx. so just install npx globally:

npm i -g npx

In Linux or Mac OS, if you found any permission related errors use sudo before it.

sudo npm i -g npx

I believe that if you download the offline ISO image file, and use that to install Visual Studio Express, you won't have to register.

Go here and find the link that says "All - Offline Install ISO image file". Click on it to expand it, select your language, and then click "Download".

Otherwise, it's possible that online registration is simply down for a while, as the error message indicates. You have 30 days before it expires, so give it a few days before starting to panic.

A shorter version of converting List to Array of specific type (for example Long):

Long[] myArray = myList.toArray(Long[]::new);

I think this provides a more thorough approach:

button, input[type="submit"], input[type="reset"] {_x000D_
 background: none;_x000D_
 color: inherit;_x000D_
 border: none;_x000D_
 padding: 0;_x000D_
 font: inherit;_x000D_
 cursor: pointer;_x000D_
 outline: inherit;_x000D_
}

<button>Example</button>

start xxx.py

You can use this for some other file types.

To get human readable string (day, month, year), you may do:

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle:NSDateFormatterMediumStyle];
NSString *string = [dateFormatter stringFromDate:dateEndDate];

add the onclick attribute

<div onclick="myFunction( event );"><span>shanghai</span><span>male</span></div>

To get the cursor to change use css's cursor rule.

div[onclick] {
  cursor: pointer;
}

The selector uses an attribute selector which does not work in some versions of IE. If you want to support those versions, add a class to your div.

Usually this happens if something is wrong with the byte array.

File.WriteAllBytes("filename.PDF", Byte[]);

This creates a new file, writes the specified byte array to the file, and then closes the file. If the target file already exists, it is overwritten.

Asynchronous implementation of this is also available.

public static System.Threading.Tasks.Task WriteAllBytesAsync 
(string path, byte[] bytes, System.Threading.CancellationToken cancellationToken = null);

Addressing an element of dictionary is like sitting on donkey and enjoy the ride.

As a rule of Python, a DICTIONARY is orderless

If there is

dic = {1: "a", 2: "aa", 3: "aaa"}

Now suppose if I go like dic[10] = "b", then it will not add like this always

dic = {1:"a",2:"aa",3:"aaa",10:"b"}

It may be like

dic = {1: "a", 2: "aa", 3: "aaa", 10: "b"}

Or

dic = {1: "a", 2: "aa", 10: "b", 3: "aaa"}

Or

dic = {1: "a", 10: "b", 2: "aa", 3: "aaa"}

Or any such combination.

So a rule of thumb is that a DICTIONARY is orderless!

I think the best solution is resize the images via script or locally and upload them again. Remember, you're forcing your viewers to download larger files than they need

@q nvarchar(max)
declare @T table(FY nvarchar(9),Qtr int,title nvarchar    (max),invoicenumber     nvarchar(max),invoicedate datetime,sp decimal    18,2),grandtotal decimal(18,2))
declare @data cursor
set @data= Cursor

select x.DBTitle,y.CurrentFinancialYear from [Accounts     Manager].dbo.DBManager x inner join [Accounts Manager].dbo.Accounts y on        y.DBID=x.DBID where x.cfy=1

begin
set @q=N'Select '''+@b+''' [fy], case cast(month(i.invoicedate)/3.1 as int)     when 0 then 4 else cast(month(i.invoicedate)/3.1 as int) end [Qtr],     l.title,i.invoicenumber,i.invoicedate,i.sp,i.grandtotal from     ['+@c+'].dbo.invoicemain i inner join  ['+@c+'].dbo.ledgermain l on     l.ledgerid=i.ledgerid where (sp=0 or stocktype=''x'') and invoicetype=''DS'''

insert into @T exec [master].dbo.sp_executesql @q fetch next from @data into @c,@b end close @data deallocate @data select * from @T return end

Something like this should do:

function cleanLocalStorage() {
    for(key in localStorage) {
        delete localStorage[key];
    }
}

Be careful about using this, though, as the user may have other data stored in localStorage and would probably be pretty ticked if you deleted that. I'd recommend either a) not storing the user's data in localStorage or b) storing the user's account stuff in a single variable, and then clearing that instead of deleting all the keys in localStorage.

Edit: As Lyn pointed out, you'll be good with localStorage.clear(). My previous points still stand, however.

Use the TextBox's Exit event handler:

Private Sub TextBox1_Exit(ByVal Cancel As MSForms.ReturnBoolean)
    Logincode_Click

Taking Milad's suggestion a bit further, you can break your document source down and then do another find, continuing until you find the unmatched culprit.

When you are working with many modules (using a CMS), or don't have access to the W3C tool (because you are working locally), this approach is really helpful.

If you're going to nest ternary operators, I believe you'd want to do something like this:

   var audience = (countrycode == 'eu') ? 'audienceEU' :
                  (countrycode == 'jp') ? 'audienceJP' :
                  (countrycode == 'cn') ? 'audienceCN' :
                  'audienceUS';

It's a lot more efficient to write/read than:

var audience = 'audienceUS';
if countrycode == 'eu' {
   audience = 'audienceEU';
} else if countrycode == 'jp' {
   audience = 'audienceJP';
} else if countrycode == 'cn' {
   audience = 'audienceCN';
}

As with all good programming, whitespace makes everything nice for people who have to read your code after you're done with the project.

I used this code. It should work.

function get_request_method() {
    $request_method = strtolower($_SERVER['REQUEST_METHOD']);

    if($request_method != 'get' && $request_method != 'post') {
        return $request_method;
    }

    if($request_method == 'post' && isset($_POST['_method'])) {
        return strtolower($_POST['_method']);
    }

    return $request_method;
}

This above code will work with REST calls and will also work with html form

<form method="post">
    <input name="_method" type="hidden" value="delete" />
    <input type="submit" value="Submit">
</form>

Maybe I'm a straight thinker but I'm a bit puzzled, don't you know the column number of your table?

By the way IE6 doesn't honor the colspan="0", with or without a colgroup defined. I tried also to use thead and th to generate the groups of columns but the browser doesn't recognlise the form colspan="0".

I've tried with Firefox 3.0 on windows and linux and it works only with a strict doctype.

You can check a test on several bowser at

http://browsershots.org/http://hsivonen.iki.fi/test/wa10/tables/colspan-0.html

I found the test page here http://hsivonen.iki.fi/test/wa10/tables/colspan-0.html

Edit: Please copy and paste the link, the formatting won't accept the double protocol parts in the link (or I am not so smart to correctly format it).

List is an interface. It doesn't have methods. When you call a method on a List reference, it in fact calls the method of ArrayList in both cases.

And for the future you can change List obj = new ArrayList<> to List obj = new LinkList<> or other types which implement List interface.

What you want to do is separate the content of the table from the header of the table. You want only the <th> elements to be scrolled. You can easily define this separation in HTML with the <tbody> and the <thead> elements.
Now the header and the body of the table are still connected to each other, they will still have the same width (and same scroll properties). Now to let them not 'work' as a table anymore you can set the display: block. This way <thead> and <tbody> are separated.

table tbody, table thead
{
    display: block;
}

Now you can set the scroll to the body of the table:

table tbody 
{
   overflow: auto;
   height: 100px;
}

And last, because the <thead> doesn't share the same width as the body anymore, you should set a static width to the header of the table:

th
{
    width: 72px;
}

You should also set a static width for <td>. This solves the issue of the unaligned columns.

td
{
    width: 72px;
}

<tr>
     <th>head1</th>
     <th>head2</th>
     <th>head3</th>
     <th>head4</th>
</tr>

I hope this is what you meant.

jsFiddle

Addendum

If you would like to have more control over the column widths, have them to vary in width between each other, and course keep the header and body columns aligned, you can use the following example:

    table th:nth-child(1), td:nth-child(1) { min-width: 50px;  max-width: 50px; }
    table th:nth-child(2), td:nth-child(2) { min-width: 100px; max-width: 100px; }
    table th:nth-child(3), td:nth-child(3) { min-width: 150px; max-width: 150px; }
    table th:nth-child(4), td:nth-child(4) { min-width: 200px; max-width: 200px; }

format(99999999,scientific = F)

gives

99999999

import difflib
f=open('a.txt','r')  #open a file
f1=open('b.txt','r') #open another file to compare
str1=f.read()
str2=f1.read()
str1=str1.split()  #split the words in file by default through the spce
str2=str2.split()
d=difflib.Differ()     # compare and just print
diff=list(d.compare(str2,str1))
print '\n'.join(diff)

Setting JAVA_INCLUDE_DIR to where jni.h is located should solve your problem (setting CPPFLAGS did not work for me)

Assuming it is /usr/lib64/java/include;

export JAVA_INCLUDE_DIR=/usr/lib64/java/include

One way is using the immediate selector and negative margin. This rule will select a list right after a paragraph, so it's just setting a negative margin-top.

p + ul {  
   margin-top: -XX;
}

I have used enum FragmentTags to define all my fragment classes.

TAG_FOR_FRAGMENT_A(A.class),
TAG_FOR_FRAGMENT_B(B.class),
TAG_FOR_FRAGMENT_C(C.class)

pass FragmentTags.TAG_FOR_FRAGMENT_A.name() as fragment tag.

and now on

@Override
public void onBackPressed(){
   FragmentManager fragmentManager = getFragmentManager();
   Fragment current
   = fragmentManager.findFragmentById(R.id.fragment_container);
    FragmentTags fragmentTag = FragmentTags.valueOf(current.getTag());

  switch(fragmentTag){
    case TAG_FOR_FRAGMENT_A:
        finish();
        break;
   case TAG_FOR_FRAGMENT_B:
        fragmentManager.popBackStack();
        break;
   case default: 
   break;
}

UPDATE

If you are working in a particular project I highly recommend using editorconfig.

It lets you define an .editorconfig file at the root of your repository defining the indentation you want to use for each file type across your repository.

For example:

root = true

[*.css]
charset = utf-8
indent_style = space
indent_size = 4

[*.js]
charset = utf-8
indent_style = space
indent_size = 2

There is a vim plugin that automatically configures vim according to the config file for file you open.

On top of that the .editorconfig file is automatically supported on many other IDEs and editors so it is the best option for collaborating between users with different environments.

If you need to change sizes often and you don't want to bind this to a specific file type you can have predefined commands on your .vimrc file to quickly switch preferences:

nmap <leader>t :set expandtab tabstop=4 shiftwidth=4 softtabstop=4<CR>
nmap <leader>m :set expandtab tabstop=2 shiftwidth=2 softtabstop=2<CR>

This maps two different sets of sizes to keys \t and \m. You can rebind this to whatever keys you want.

here is simple code

List <String> list = new ArrayList <String>();
list.add("a");
list.add("b");
JSONArray array = new JSONArray();
for (int i = 0; i < list.size(); i++) {
        array.put(list.get(i));
}
JSONObject obj = new JSONObject();
try {
    obj.put("result", array);
} catch (JSONException e) {
 // TODO Auto-generated catch block
e.printStackTrace();
}
pw.write(obj.toString());

If you are using Entity Framework 5 < you can use DbGeography. Example from MSDN:

public class University  
{ 
    public int UniversityID { get; set; } 
    public string Name { get; set; } 
    public DbGeography Location { get; set; } 
}

public partial class UniversityContext : DbContext 
{ 
    public DbSet<University> Universities { get; set; } 
}

using (var context = new UniversityContext ()) 
{ 
    context.Universities.Add(new University() 
        { 
            Name = "Graphic Design Institute", 
            Location = DbGeography.FromText("POINT(-122.336106 47.605049)"), 
        }); 

    context. Universities.Add(new University() 
        { 
            Name = "School of Fine Art", 
            Location = DbGeography.FromText("POINT(-122.335197 47.646711)"), 
        }); 

    context.SaveChanges(); 

    var myLocation = DbGeography.FromText("POINT(-122.296623 47.640405)"); 

    var university = (from u in context.Universities 
                        orderby u.Location.Distance(myLocation) 
                        select u).FirstOrDefault(); 

    Console.WriteLine( 
        "The closest University to you is: {0}.", 
        university.Name); 
}

Something I struggled with then I started using DbGeography was the coordinateSystemId. See the answer below for an excellent explanation and source for the code below.

public class GeoHelper
{
    public const int SridGoogleMaps = 4326;
    public const int SridCustomMap = 3857;

    public static DbGeography FromLatLng(double lat, double lng)
    {
        return DbGeography.PointFromText(
            "POINT("
            + lng.ToString() + " "
            + lat.ToString() + ")",
            SridGoogleMaps);
    }
}

I'm assuming the contents of src/main/resources/ is copied to WEB-INF/classes/ inside your .war at build time. If that is the case you can just do (substituting real values for the classname and the path being loaded).

URL sqlScriptUrl = MyServletContextListener.class
                       .getClassLoader().getResource("sql/script.sql");

There is an easier way to get the exact version .NET version installed on your machine from a cmd prompt. Just follow the following instructions;

1. Open the command prompt (i.e Windows + R ? type "cmd").
2. Type the following command, all on one line:

reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP"

(This will list all the .NET versions.)

3. If you want to check the latest .NET 4 version.
4. Type following instruction, on a single line:

reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\full" /v version

Please find the attached image below to see how it is shown.

Update 2018, SDK >= 23.

Now you should also check if the user has granted permission to external storage by using:

public boolean isStoragePermissionGranted() {
    String TAG = "Storage Permission";
    if (Build.VERSION.SDK_INT >= 23) {
        if (this.checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
                == PackageManager.PERMISSION_GRANTED) {
            Log.v(TAG, "Permission is granted");
            return true;
        } else {
            Log.v(TAG, "Permission is revoked");
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
            return false;
        }
    }
    else { //permission is automatically granted on sdk<23 upon installation
        Log.v(TAG,"Permission is granted");
        return true;
    }
}

public void saveImageBitmap(Bitmap image_bitmap, String image_name) {
    String root = Environment.getExternalStorageDirectory().toString();
    if (isStoragePermissionGranted()) { // check or ask permission
        File myDir = new File(root, "/saved_images");
        if (!myDir.exists()) {
            myDir.mkdirs();
        }
        String fname = "Image-" + image_name + ".jpg";
        File file = new File(myDir, fname);
        if (file.exists()) {
            file.delete();
        }
        try {
            file.createNewFile(); // if file already exists will do nothing
            FileOutputStream out = new FileOutputStream(file);
            image_bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
            out.flush();
            out.close();

        } catch (Exception e) {
            e.printStackTrace();
        }

        MediaScannerConnection.scanFile(this, new String[]{file.toString()}, new String[]{file.getName()}, null);
    }
}

and of course, add in the AndroidManifest.xml:

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

Just found out the hard way that it is

SELECT 1 FROM DUAL

for MaxDB as well.

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)

If you have to disable SSL checks for one git server hosting several repositories, you can run :

git config --bool --add http.https://my.bad.server.sslverify false

This will add it to your user's configuration.

Command to check:

git config --bool --get-urlmatch http.sslverify https://my.bad.server 

(If you still use git < v1.8.5, run git config --global http.https://my.bad.server.sslVerify false)

Explanation from the documentation where the command is at the end, show the .gitconfig content looking like:

[http "https://my.bad.server"]
        sslVerify = false

It will ignore any certificate checks for this server, whatever the repository.

You also have some explanation in the code

This solution is based from this website: http://social.msdn.microsoft.com/Forums/en-US/bd0ee306-7bb5-4ce4-8341-edd9475f84ad/excel-2007-use-vba-to-download-save-csv-from-url

It is slightly modified to overwrite existing file and to pass along login credentials.

Sub DownloadFile()

Dim myURL As String
myURL = "https://YourWebSite.com/?your_query_parameters"

Dim WinHttpReq As Object
Set WinHttpReq = CreateObject("Microsoft.XMLHTTP")
WinHttpReq.Open "GET", myURL, False, "username", "password"
WinHttpReq.send

If WinHttpReq.Status = 200 Then
    Set oStream = CreateObject("ADODB.Stream")
    oStream.Open
    oStream.Type = 1
    oStream.Write WinHttpReq.responseBody
    oStream.SaveToFile "C:\file.csv", 2 ' 1 = no overwrite, 2 = overwrite
    oStream.Close
End If

End Sub

Note: You can use memset with any character.

Example:

int arr[20];
memset(arr, 'A', sizeof(arr));

Also could be partially filled

int arr[20];
memset(&arr[5], 0, 10);

But be carefull. It is not limited for the array size, you could easily cause severe damage to your program doing something like this:

int arr[20];
memset(arr, 0, 200);

It is going to work (under windows) and zero memory after your array. It might cause damage to other variables values.

1. Improper use of eval opens up your code for injection attacks

2. Debugging can be more challenging (no line numbers, etc.)

3. eval'd code executes slower (no opportunity to compile/cache eval'd code)

Edit: As @Jeff Walden points out in comments, #3 is less true today than it was in 2008. However, while some caching of compiled scripts may happen this will only be limited to scripts that are eval'd repeated with no modification. A more likely scenario is that you are eval'ing scripts that have undergone slight modification each time and as such could not be cached. Let's just say that SOME eval'd code executes more slowly.

Since the encoding that turns "the Family" into "t?? T???ly" is effectively random and not following any algorithm that can be explained by the information of the Unicode codepoints involved, there's no general way to solve this algorithmically.

You will need to build the mapping of Unicode characters into latin characters which they resemble. You could probably do this with some smart machine learning on the actual glyphs representing the Unicode codepoints. But I think the effort for this would be greater than manually building that mapping. Especially if you have a good amount of examples from which you can build your mapping.

To clarify: a few of the substitutions can actually be solved via the Unicode data (as the other answers demonstrate), but some letters simply have no reasonable association with the latin characters which they resemble.

Examples:

• "?" (U+0452 CYRILLIC SMALL LETTER DJE) is more related to "d" than to "h", but is used to represent "h".
• "T" (U+0166 LATIN CAPITAL LETTER T WITH STROKE) is somewhat related to "T" (as the name suggests) but is used to represent "F".
• "?" (U+0E04 THAI CHARACTER KHO KHWAI) is not related to any latin character at all and in your example is used to represent "a"

please see this article http://netjunky.net/sed-replace-path-with-slash-separators/

Just using | instead of /

I also had the same error:

***************************
APPLICATION FAILED TO START
***************************

Description:

Field repository in com.kalsym.next.gen.campaign.controller.CampaignController required a bean of type 'com.kalsym.next.gen.campaign.data.CustomerRepository' that could not be found.


Action:

Consider defining a bean of type 'com.kalsym.next.gen.campaign.data.CustomerRepository' in your configuration.de here

And my packages were constructed in the same way as mentioned in the accepted answer. I fixed my issue by adding EnableMongoRepositories annotation in the main class like this:

@SpringBootApplication
@EnableMongoRepositories(basePackageClasses = CustomerRepository.class)
public class CampaignAPI {

    public static void main(String[] args) {
        SpringApplication.run(CampaignAPI.class, args);
    }
}

If you need to add multiple don't forget the curly braces:

@EnableMongoRepositories(basePackageClasses
    = {
        MSASMSRepository.class, APartyMappingRepository.class
    })

According to this documentation, the find method will search down through the tree of elements until it finds the element in the selector parameters. So $(parentSelector).find(childSelector) is the fastest and most efficient way to do this.

Slight variation on above:

1. Eliminates period for case (10000.0).
2. Breaks after first period is processed.

Code here:

void EliminateTrailingFloatZeros(char *iValue)
{
  char *p = 0;
  for(p=iValue; *p; ++p) {
    if('.' == *p) {
      while(*++p);
      while('0'==*--p) *p = '\0';
      if(*p == '.') *p = '\0';
      break;
    }
  }
}

It still has potential for overflow, so be careful ;P

I wrote this awhile back. It assumes the delimiter is a comma and that the individual values aren't bigger than 127 characters. It could be modified pretty easily.

It has the benefit of not being limited to 4,000 characters.

Good luck!

Just FYI, you could use the VB.NET Like-Operator:

string text = "x is not the same as X and yz not the same as YZ";
bool contains = LikeOperator.LikeString(text,"*X*YZ*", Microsoft.VisualBasic.CompareMethod.Binary);  

Use CompareMethod.Text if you want to ignore the case.

You need to add using Microsoft.VisualBasic.CompilerServices;.

<MyComponent /> compiles to React.createElement(MyComponent, {}), which expects a string (HTML tag) or a function (ReactClass) as first parameter.

You could just store your component class in a variable with a name that starts with an uppercase letter. See HTML tags vs React Components.

var MyComponent = Components[type + "Component"];
return <MyComponent />;

compiles to

var MyComponent = Components[type + "Component"];
return React.createElement(MyComponent, {});

Update Nov -2017

1) Go to Mongo DB download center https://www.mongodb.com/download-center#community and pick a flavor of MongoDB you want to install. You can pick from

• MongoDB Atlas - MongoDB database in the cloud
• Communiy Server - MongoDb for windows (with and without SSL),iOS, Linux
• OpManger- Mongo Db for Data Center
• Compass - UI tool for MongoDB

To know your OS version run this command in cmd prompt

wmic os get caption

To know your CPU architecture(32 or 64 bit) run this command in cmd prompt

wmic os get osarchitecture

I am using Community version (150MBs- GNU license)

2) Click on MSI and go through installation Process. Exe will install MongoDb and SSL required by the DB.

Mongo DB should be installed on your C drive

C:\Program Files\MongoDB

MongoDB is self-contained, it means and does not have any other system dependencies. If you are low on disk in C drive then you can run MongoDB from any folder you choose.

You can now run mongodb.exe from bin folder. If you get Visual C++ error for missing dlls then download Visual C++ Redistributable from

https://www.microsoft.com/en-in/download/details.aspx?id=48145

After installation, try to rerun mongo.exe.

One other way to work around this is using something like this when using mysqlclient in python.

suppose the data you want to enter is like this <ol><li><strong style="background-color: rgb(255, 255, 0);">Saurav\'s List</strong></li></ol>. It contains both double qoute and single quote.

You can use the following method to escape the quotes:

statement = """ Update chats set html='{}' """.format(html_string.replace("'","\\\'"))

Note: three \ characters are needed to escape the single quote which is there in unformatted python string.

you can also use ranges by using:

b = df[(df['a'] > 1) & (df['a'] < 5)]

Perhaps something like this for the first problem, you can simply access the columns by their names:

>>> df = pd.DataFrame(np.random.rand(4,5), columns = list('abcde'))
>>> df[df['c']>.5][['b','e']]
          b         e
1  0.071146  0.132145
2  0.495152  0.420219

For the second problem:

>>> df[df['c']>.5][['b','e']].values
array([[ 0.07114556,  0.13214495],
       [ 0.49515157,  0.42021946]])

While using vim to do it is perfectly possible, why don't you simply use iconv? I mean - loading text editor just to do encoding conversion seems like using too big hammer for too small nail.

Just:

iconv -f utf-16 -t utf-8 file.xml > file.utf8.xml

And you're done.

Perhaps the easiest way to see which extensions are (compiled and) loaded (not in cli) is to have a server run the following:

<?php
$ext = get_loaded_extensions();
asort($ext);
foreach ($ext as $ref) {
    echo $ref . "\n";
}

PHP cli does not necessarily have the same extensions loaded.

.inspect is what you're looking for, it's way easier IMO than .to_yaml!

user = User.new
user.name = "will"
user.email = "[email protected]"

user.inspect
#<name: "will", email: "[email protected]">

I recommend more understanding way using extension method:

public static class KeyValuePairExtensions
{
    public static bool IsNull<T, TU>(this KeyValuePair<T, TU> pair)
    {
        return pair.Equals(new KeyValuePair<T, TU>());
    }
}

And then just use:

var countries = new Dictionary<string, string>
{
    {"cz", "prague"},
    {"de", "berlin"}
};

var country = countries.FirstOrDefault(x => x.Key == "en");

if(country.IsNull()){

}

Just a note for people who may have found this later (and want java way of achieving this); FirefoxOptions is also capable of enabling the headless mode:

FirefoxOptions firefoxOptions = new FirefoxOptions();
firefoxOptions.setHeadless(true);

I resolved it by replacing Tomcat 8.5.* with Tomcat 7.0.* version.

This might be a bit of a hack, but I avoided the issue and converted the json into PHP's POST array on the server side:

$_POST = json_decode(file_get_contents('php://input'), true);

Today at midnight. Easy.

$stamp = mktime(0, 0, 0);

I found a better way of doing it so you can get a input from a txtbox or have something be generated in that text box and be able to click a button to do it.!

import java.awt.datatransfer.*;
import java.awt.Toolkit;

private void /* Action performed when the copy to clipboard button is clicked */ {
    String ctc = txtCommand.getText().toString();
    StringSelection stringSelection = new StringSelection(ctc);
    Clipboard clpbrd = Toolkit.getDefaultToolkit().getSystemClipboard();
    clpbrd.setContents(stringSelection, null);
}

// txtCommand is the variable of a text box

For me (selectionChange) and the suggested (onSelectionChange) didn't work and I'm not using ReactiveForms. What I ended up doing was using the (valueChange) event like:

<mat-select (valueChange)="someFunction()">

And this worked for me

im not really that good at C , but i believe this code should get you complete single line till the end...

 #include<stdio.h>

 int main()   
{      
  char line[1024];    
  FILE *f=fopen("filename.txt","r");    
  fscanf(*f,"%[^\n]",line);    
  printf("%s",line);    
 }    

Distinct will sort records in ascending order. If you want to sort in desc order use:

SELECT DISTINCT Category
FROM MonitoringJob
ORDER BY Category DESC

If you want to sort records based on CreationDate field then this field must be in the select statement:

SELECT DISTINCT Category, creationDate
FROM MonitoringJob
ORDER BY CreationDate DESC

Looks to me like you need to set the yellow on #doc3 and then get rid of the white that is called out on the #yui-main (which is covering up the color of the #doc3). This gets you yellow between header and footer.

you can use like this situation: for example, you have a page: http://www.example.com/page.php then in that page.php, insert this code:

if (!empty($_GET['doaction']) && $_GET['doaction'] == blabla ){
echo '<script>alert("hello");</script>';
}

then, whenever you visit this url: http://www.example.com/page.php?doaction=blabla

then the alert will be automatically called.

I put together a short function that allows for a little more flexibility when inserting a row:

def insert_row(idx, df, df_insert):
    dfA = df.iloc[:idx, ]
    dfB = df.iloc[idx:, ]

    df = dfA.append(df_insert).append(dfB).reset_index(drop = True)

    return df

which could be further shortened to:

def insert_row(idx, df, df_insert):
    return df.iloc[:idx, ].append(df_insert).append(df.iloc[idx:, ]).reset_index(drop = True)

Then you could use something like:

df = insert_row(2, df, df_new)

where 2 is the index position in df where you want to insert df_new.

According to the Docs you need to put an id on each link in the header and that link needs to be inside the li which should have no other styles, i.e doesn't need all the data-target stuff in the li. Your list has with no data-toggle or id.

Your HTML would be like this

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>_x000D_

   <div class="tab-pane" id="c">CCC</div>_x000D_
   <div class="tab-pane" id="d">DDD</div>_x000D_
</div>

And you shouldn't need any Javascript, according to the Docs

You can use the information schema system views to find out pretty much anything about the tables you're interested in:

SELECT *
  FROM INFORMATION_SCHEMA.COLUMNS
 WHERE TABLE_NAME = 'yourTableName'
 ORDER BY ORDINAL_POSITION

You can also interrogate views, stored procedures and pretty much anything about the database using the Information_schema views.

There are two approaches you can take, to have a hovered element affect (E) another element (F):

1. F is a child-element of E, or
2. F is a later-sibling (or sibling's descendant) element of E (in that E appears in the mark-up/DOM before F):

To illustrate the first of these options (F as a descendant/child of E):

.item:hover .wrapper {
    color: #fff;
    background-color: #000;
}?

To demonstrate the second option, F being a sibling element of E:

.item:hover ~ .wrapper {
    color: #fff;
    background-color: #000;
}?

In this example, if .wrapper was an immediate sibling of .item (with no other elements between the two) you could also use .item:hover + .wrapper.

After half a day of fiddling with this, found out that PDO had a bug where...

--

//This would run as expected:
$pdo->exec("valid-stmt1; valid-stmt2;");

--

//This would error out, as expected:
$pdo->exec("non-sense; valid-stmt1;");

--

//Here is the bug:
$pdo->exec("valid-stmt1; non-sense; valid-stmt3;");

It would execute the "valid-stmt1;", stop on "non-sense;" and never throw an error. Will not run the "valid-stmt3;", return true and lie that everything ran good.

I would expect it to error out on the "non-sense;" but it doesn't.

Here is where I found this info: Invalid PDO query does not return an error

Here is the bug: https://bugs.php.net/bug.php?id=61613

So, I tried doing this with mysqli and haven't really found any solid answer on how it works so I thought I's just leave it here for those who want to use it..

try{
    // db connection
    $mysqli = new mysqli("host", "user" , "password", "database");
    if($mysqli->connect_errno){
        throw new Exception("Connection Failed: [".$mysqli->connect_errno. "] : ".$mysqli->connect_error );
        exit();
    }

    // read file.
    // This file has multiple sql statements.
    $file_sql = file_get_contents("filename.sql");

    if($file_sql == "null" || empty($file_sql) || strlen($file_sql) <= 0){
        throw new Exception("File is empty. I wont run it..");
    }

    //run the sql file contents through the mysqli's multi_query function.
    // here is where it gets complicated...
    // if the first query has errors, here is where you get it.
    $sqlFileResult = $mysqli->multi_query($file_sql);
    // this returns false only if there are errros on first sql statement, it doesn't care about the rest of the sql statements.

    $sqlCount = 1;
    if( $sqlFileResult == false ){
        throw new Exception("File: '".$fullpath."' , Query#[".$sqlCount."], [".$mysqli->errno."]: '".$mysqli->error."' }");
    }

    // so handle the errors on the subsequent statements like this.
    // while I have more results. This will start from the second sql statement. The first statement errors are thrown above on the $mysqli->multi_query("SQL"); line
    while($mysqli->more_results()){
        $sqlCount++;
        // load the next result set into mysqli's active buffer. if this fails the $mysqli->error, $mysqli->errno will have appropriate error info.
        if($mysqli->next_result() == false){
            throw new Exception("File: '".$fullpath."' , Query#[".$sqlCount."], Error No: [".$mysqli->errno."]: '".$mysqli->error."' }");
        }
    }
}
catch(Exception $e){
    echo $e->getMessage(). " <pre>".$e->getTraceAsString()."</pre>";
}

Here is my preferred way to check for "if null or empty":

SELECT * 
FROM UserProfile 
WHERE PropertydefinitionID in (40, 53) 
AND NULLIF(PropertyValue, '') is null

Since it modifies the search argument (SARG) it might have performance issues because it might not use an existing index on the PropertyValue column.

Login to any other EC2 instance you have that has access to the RDS instance in question and has mysqladmin installed and run

mysqladmin -h <RDS ENDPOINT URL> -P 3306 -u <USER> -p flush-hosts

you will be prompted for your password

As the OP said that he wants letters and numbers ONLY (no underscore!), one more way to have this in php regex is to use posix expressions:

/^[[:alnum:]]+$/

Note: This will not work in Java, JavaScript, Python, Ruby, .NET

Something like this should work:

<%=Html.TextBox("test", new { style="width:50px" })%>

Or better:

<%=Html.TextBox("test")%>

<style type="text/css">
    input[type="text"] { width:50px; }     
</style>

Based on Cameron's initial answer, here is what I've just added at my enhanced version of SilverFlow library's FloatingWindowHost (copying from FloatingWindowHost.cs at http://clipflair.codeplex.com source code)

    public int MaxZIndex
    {
      get {
        return FloatingWindows.Aggregate(-1, (maxZIndex, window) => {
          int w = Canvas.GetZIndex(window);
          return (w > maxZIndex) ? w : maxZIndex;
        });
      }
    }

    private void SetTopmost(UIElement element)
    {
        if (element == null)
            throw new ArgumentNullException("element");

        Canvas.SetZIndex(element, MaxZIndex + 1);
    }

Worth noting regarding the code above that Canvas.ZIndex is an attached property available for UIElements in various containers, not just used when being hosted in a Canvas (see Controlling rendering order (ZOrder) in Silverlight without using the Canvas control). Guess one could even make a SetTopmost and SetBottomMost static extension method for UIElement easily by adapting this code.

To set it programmatically in Activity.java:

  super.onCreate(savedInstanceState);

  setTheme(R.style.MyTheme); // (for Custom theme)
  setTheme(android.R.style.Theme_Holo); // (for Android Built In Theme)

  this.setContentView(R.layout.myactivity);

To set in Application scope in Manifest.xml (all activities):

 <application
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To set in Activity scope in Manifest.xml (single activity):

  <activity
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To build a custom theme, you will have to declare theme in themes.xml file, and set styles in styles.xml file.

This may work for you:

set define off

Otherwise the ampersand needs to be at the end of a string,

'StackOverflow &' || ' you'

EDIT: I was click-happy when saving... This was referenced from a blog.

Since you are using a Mac, open a terminal, and

• cd /etc

Find the php.ini, and sudo open it, for example, using the nano editor

• nano php.ini

Find use control+w to search for "mysqli.default_socket", and change the line to

• mysqli.default_socket = /tmp/mysql.sock

Use control+x and then hit "y" and "return" to save the file. Restart Aapche if necessary.

Now you should be able to run mysqli.

wait until the process is over ...

while(webview.getProgress()< 100){}
progressBar.setVisibility(View.GONE);

Why not rewrite it to be

for element in somelist: 
   do_action(element)  

if check(element): 
    remove_element_from_list

See this question for how to remove from the list, though it looks like you've already seen that Remove items from a list while iterating

Another option is to do this if you really want to keep this the same

newlist = [] 
for element in somelist: 
   do_action(element)  

   if not check(element): 
      newlst.append(element)

UPDATE

The Google maps API v2 is now installed on the latest Google system images (api:19 ARM or x86).
So your application should just work with the new images. There is no need to install these files.

I've been trying to run an Android Google Maps V2 application under an emulator and once I finally got Google Play Services running, I updated my SDK to Google Play Services revision 4, and my emulator wouldn't run my application any more.

I have now worked out how to update my emulator from my transformer tablet. (You won't need a tablet as you can download the files below.)

I used Titanium Backup to backup my Asus Eee Pad Transformer (TF101) and then grabbed the com.android.vending and the com.google.android.gms APK files from the backup.

I installed these on an emulator configured with platform: 4.1.2, API Level: 16, CPU Intel/Atom x86) and my Google Maps V2 application works again.

That was all .. none of the other steps regarding /system/app were required.

My application only uses the Google Maps API, no doubt, more steps are required if you use other Google Play services.

New files for latest Google Play services:

• com.google.android.gms-20140218.apk

• com.android.vending-20140218.apk

Same instructions as before: Create a new emulator with any CPU/ABI, a non-Google API target (versions 10-19 work) and GPU emulation on or off, and then install the files:

adb install com.android.vending-20140218.apk
adb install com.google.android.gms-20140218.apk

If you are upgrading an existing emulator then you might need to uninstall previous versions by:

adb uninstall com.android.vending
adb uninstall com.google.android.gms

That's all.

This one helped me,

res.format({
        json:function(){
                            var responseData    = {};
                            responseData['status'] = 200;
                            responseData['outputPath']  = outputDirectoryPath;
                            responseData['sourcePath']  = url;
                            responseData['message'] = 'Scraping of requested resource initiated.';
                            responseData['logfile'] = logFileName;
                            res.json(JSON.stringify(responseData));
                        }
    });

For Swift user with designable option:

1. Create a custom UIView subclass and a xib files, that we will name after our own class name: in our case MemeView. Inside the Meme View class remember to define it as designable with the @IBDesignable attribute before the class declaration

2. Rember to set the File’s Owner in the xib with our custom UIView subclass in Indetity Inspector panel

   

3. In the xib file now we can build our interface, make constraints, create outlets, actions etc.

4. We need to implement few methods to our custom class to open the xib once initialized

   class XibbedView: UIView {

   weak var nibView: UIView!
   
   override convenience init(frame: CGRect) {
       let nibName = NSStringFromClass(self.dynamicType).componentsSeparatedByString(".").last!
       self.init(nibName: nibName)
   }
   
   required init?(coder aDecoder: NSCoder) {
       super.init(coder: aDecoder)
       let nibName = NSStringFromClass(self.dynamicType).componentsSeparatedByString(".").last!
       let nib = loadNib(nibName)
       nib.frame = bounds
       nib.translatesAutoresizingMaskIntoConstraints = false
       addSubview(nib)
       nibView = nib
       setUpConstraints()
   }
   
   init(nibName: String) {
       super.init(frame: CGRectZero)
       let nibName = NSStringFromClass(self.dynamicType).componentsSeparatedByString(".").last!
       let nib = loadNib(nibName)
       nib.frame = bounds
       nib.translatesAutoresizingMaskIntoConstraints = false
       addSubview(nib)
       nibView = nib
       setUpConstraints()
   }
   
   func setUpConstraints() {
       ["V","H"].forEach { (quote) -> () in
           let format = String(format:"\(quote):|[nibView]|")
           addConstraints(NSLayoutConstraint.constraintsWithVisualFormat(format, options: [], metrics: nil, views: ["nibView" : nibView]))
       }
   }
   
   func loadNib(name: String) -> UIView {
       let bundle = NSBundle(forClass: self.dynamicType)
       let nib = UINib(nibName: name, bundle: bundle)
       let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView
   
       return view
   }
   

   }

5. In our custom class we can also define some inspecatable properties to have full control over them from interface builder
   

   @IBDesignable class MemeView: XibbedView {

   @IBInspectable var memeImage: UIImage = UIImage() {
       didSet {
           imageView.image = memeImage
       }
   }
   @IBInspectable var textColor: UIColor = UIColor.whiteColor() {
       didSet {
           label.textColor = textColor
       }
   }
   @IBInspectable var text: String = "" {
       didSet {
           label.text = text
       }
   }
   @IBInspectable var roundedCorners: Bool = false {
       didSet {
           if roundedCorners {
               layer.cornerRadius = 20.0
               clipsToBounds = true
           }
           else {
               layer.cornerRadius = 0.0
               clipsToBounds = false
           }
       }
   }
   
   @IBOutlet weak var label: UILabel!
   @IBOutlet weak var imageView: UIImageView!
   

}

Few examples:

If we need to add more information the view while is displayed inside a storyboard or another xib, to do that we can implement prepareForInterfaceBuilder(), this method will be executed only while opening the file in interface builder. If you did everything I wrote but nothing is working, the is a way to debug a sigle view by adding breakpoints in its implementation.
Here is the views hierarchy.

Hope this helps a full sample can be downloaded here

The following code is to retrieve all the links available in a webpage using urllib2 and BeautifulSoup4:

import urllib2
from bs4 import BeautifulSoup

url = urllib2.urlopen("http://www.espncricinfo.com/").read()
soup = BeautifulSoup(url)

for line in soup.find_all('a'):
    print(line.get('href'))

You could use

System.out.printf("%4.2f%n", ((float)12345)/100));

As per the comments, 12345/100.0 would be better, as would the use of double instead of float.

The doxypy input filter allows you to use pretty much all of Doxygen's formatting tags in a standard Python docstring format. I use it to document a large mixed C++ and Python game application framework, and it's working well.

HAVING is like WHERE with aggregate functions, or you could use a subquery.

select EmployeeId, sum(amount)
from Sales
group by Employee
having sum(amount) > 20000

Or

select EmployeeId, sum(amount)
from Sales
group by Employee
where EmployeeId in (
    select max(EmployeeId) from Employees)

No. I don't see any advantage. Second one is more straitforward.

btw: Second style is found in every corners of JDK source.

The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

Two ways I've used it... first:

SET /P variable=

When batch file reaches this point (when left blank) it will halt and wait for user input. Input then becomes variable.

And second:

SET /P variable=<%temp%\filename.txt

Will set variable to contents (the first line) of the txt file. This method won't work unless the /P is included. Both tested on Windows 8.1 Pro, but it's the same on 7 and 10.

Probably because you're using unsafe code.

Are you doing something with pointers or unmanaged assemblies somewhere?

Note: This answer shows how to achieve this using only the datetime and calendar standard library (stdlib) modules - which is what was explicitly asked for. The accepted answer shows how to better achieve this with one of the many dedicated non-stdlib libraries. If you can use non-stdlib libraries, by all means do so for these kinds of date/time manipulations!

How about this?

def add_one_month(orig_date):
    # advance year and month by one month
    new_year = orig_date.year
    new_month = orig_date.month + 1
    # note: in datetime.date, months go from 1 to 12
    if new_month > 12:
        new_year += 1
        new_month -= 12

    new_day = orig_date.day
    # while day is out of range for month, reduce by one
    while True:
        try:
            new_date = datetime.date(new_year, new_month, new_day)
        except ValueError as e:
            new_day -= 1
        else:
            break

    return new_date

EDIT:

Improved version which:

1. keeps the time information if given a datetime.datetime object
2. doesn't use try/catch, instead using calendar.monthrange from the calendar module in the stdlib:

import datetime
import calendar

def add_one_month(orig_date):
    # advance year and month by one month
    new_year = orig_date.year
    new_month = orig_date.month + 1
    # note: in datetime.date, months go from 1 to 12
    if new_month > 12:
        new_year += 1
        new_month -= 12

    last_day_of_month = calendar.monthrange(new_year, new_month)[1]
    new_day = min(orig_date.day, last_day_of_month)

    return orig_date.replace(year=new_year, month=new_month, day=new_day)

Something like this should work:

INSERT INTO #IMEIS (imei) VALUES ('val1'), ('val2'), ...

UPDATE:

Apparently this syntax is only available starting on SQL Server 2008.

If you want to remove or unset all $_SESSION 's then try this

session_destroy();

If you want to remove specific $_SESSION['name'] then try this

session_unset('name');

String x = "stackoverflow";
String [] y = x.split("");

_httpClient = new HttpClient(handler) {Timeout = TimeSpan.FromSeconds(5)};

is what I usually do, seems to work out pretty good for me, its especially good when using proxies.

Video streaming is a perfect example of using UDP.

WAITFOR DELAY 'HH:MM:SS'

I believe the maximum time this can wait for is 23 hours, 59 minutes and 59 seconds.

Here's a Scalar-valued function to show it's use; the below function will take an integer parameter of seconds, which it then translates into HH:MM:SS and executes it using the EXEC sp_executesql @sqlcode command to query. Below function is for demonstration only, i know it's not fit for purpose really as a scalar-valued function! :-)

    CREATE FUNCTION [dbo].[ufn_DelayFor_MaxTimeIs24Hours]
    (
    @sec int
    )
    RETURNS
    nvarchar(4)
    AS
    BEGIN


    declare @hours int = @sec / 60 / 60
    declare @mins int = (@sec / 60) - (@hours * 60)
    declare @secs int = (@sec - ((@hours * 60) * 60)) - (@mins * 60)


    IF @hours > 23 
    BEGIN
    select @hours = 23
    select @mins = 59
    select @secs = 59
    -- 'maximum wait time is 23 hours, 59 minutes and 59 seconds.'
    END


    declare @sql nvarchar(24) = 'WAITFOR DELAY '+char(39)+cast(@hours as nvarchar(2))+':'+CAST(@mins as nvarchar(2))+':'+CAST(@secs as nvarchar(2))+char(39)


    exec sp_executesql @sql

    return ''
    END

IF you wish to delay longer than 24 hours, I suggest you use a @Days parameter to go for a number of days and wrap the function executable inside a loop... e.g..

    Declare @Days int = 5
    Declare @CurrentDay int = 1

    WHILE @CurrentDay <= @Days
    BEGIN

    --24 hours, function will run for 23 hours, 59 minutes, 59 seconds per run.
    [ufn_DelayFor_MaxTimeIs24Hours] 86400

    SELECT @CurrentDay = @CurrentDay + 1
    END

You can configure patterns to hide files and folders from the explorer and searches.

1. Open VS User Settings (Main menu: File > Preferences > Settings). This will open the setting screen.
2. Search for files:exclude in the search at the top.
3. Configure the User Setting with new glob patterns as needed. In this case add this pattern node_modules/ then click OK. The pattern syntax is powerful. You can find pattern matching details under the Search Across Files topic.

When you are done it should look something like this:

If you want to directly edit the settings file: For example to hide a top level node_modules folder in your workspace:

"files.exclude": {
    "node_modules/": true
}

To hide all files that start with ._ such as ._.DS_Store files found on OSX:

"files.exclude": {
    "**/._*": true
}

You also have the ability to change Workspace Settings (Main menu: File > Preferences > Workspace Settings). Workspace settings will create a .vscode/settings.json file in your current workspace and will only be applied to that workspace. User Settings will be applied globally to any instance of VS Code you open, but they won't override Workspace Settings if present. Read more on customizing User and Workspace Settings.

The /Date(ms + timezone)/ is a ASP.NET syntax for JSON dates. You might want to use a library like momentjs for parsing such dates. It would come in handy if you need to manipulate or print the dates any time later.

Try calling read_csv with encoding='latin1', encoding='iso-8859-1' or encoding='cp1252' (these are some of the various encodings found on Windows).

Great Thanks to @Massimo Cafaro and Shaybc I was able achieve below tasks

in iOS 8 :

Record audio & Save

Play Saved Recording

1.Add "AVFoundation.framework" to your project

in .h file

2.Add below import statement 'AVFoundation/AVFoundation.h'.

3.Define "AVAudioRecorderDelegate"

4.Create a layout with Record, Play buttons and their action methids

5.Define Recorder and Player etc.

Here is the complete example code which may help you.

ViewController.h

#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>

@interface ViewController : UIViewController <AVAudioRecorderDelegate>

@property(nonatomic,strong) AVAudioRecorder *recorder;
@property(nonatomic,strong) NSMutableDictionary *recorderSettings;
@property(nonatomic,strong) NSString *recorderFilePath;
@property(nonatomic,strong) AVAudioPlayer *audioPlayer;
@property(nonatomic,strong) NSString *audioFileName;

- (IBAction)startRecording:(id)sender;
- (IBAction)stopRecording:(id)sender;

- (IBAction)startPlaying:(id)sender;
- (IBAction)stopPlaying:(id)sender;

@end

Then do the job in

ViewController.m

#import "ViewController.h"

#define DOCUMENTS_FOLDER [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]

@interface ViewController ()
@end

@implementation ViewController

@synthesize recorder,recorderSettings,recorderFilePath;
@synthesize audioPlayer,audioFileName;

I found a workaround.

1. Export with a white background (or other color that will work with transparent graphics). This will be out "whitescreen" layer.
2. Export with "bluescreen" background, or some terrible other color that will make it easy to select out the background from foreground.
3. Open the bluescreen version as a layer on top of the white screen.
4. Use the bluescreen layer to select out only the parts you want to use.
5. Create a mask for the whitescreen layer with the selection made from the bluescreen layer.

This will get good results for edges and aliasing, whilst retaining a good color for the see-

1. First Replace the MySQL dependency as given below

   <dependency>
       <groupId>mysql</groupId>
       <artifactId>mysql-connector-java</artifactId>
       <version>5.1.44</version>
   </dependency>
   

2. An error showing "Authentication plugin 'caching_sha2_password'" will appear. Run this command:

   mysql -u root -p
   ALTER USER 'username'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
   

Well, the shortest way I know of, is following:

psql -U {user_name} -d {database_name} -f {file_path} -h {host_name}

database_name: Which database should you insert your file data in.

file_path: Absolute path to the file through which you want to perform the importing.

host_name: The name of the host. For development purposes, it is mostly localhost.

Upon entering this command in console, you will be prompted to enter your password.
