For flutter projects you can also solve this issue

open your \android\app\build.gradle

you sould have the following:

android {
    defaultConfig {
        ...
        minSdkVersion 16
        targetSdkVersion 28

    }

}

If your minSdkVersion is set to 21 or higher, all you need to do is set multiDexEnabled to true in the defaultConfig. Like this

android {
    defaultConfig {
        ...
        minSdkVersion 16
        targetSdkVersion 28
        multiDexEnabled true 

    }

}

if your minSdkVersion is set to 20 or lower add multiDexEnabled true to the defaultConfig

And define the implementation

dependencies {
  implementation 'com.android.support:multidex:1.0.3'// or 2.0.1
}

At the end you should have:

android {
    defaultConfig {
        ...
        minSdkVersion 16
        targetSdkVersion 28
        multiDexEnabled true  // added this
    }

}

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}

Another option that helped me is using pathlib:

from pathlib import Path
p = Path('.') ## if you want to write to current directory
with open(p / 'test.txt', 'w') as f:
    f.write('test message')

and it works

the reason why it returns < filter object > is that, filter is class instead of built-in function.

help(filter) you will get following: Help on class filter in module builtins:

class filter(object)
 |  filter(function or None, iterable) --> filter object
 |  
 |  Return an iterator yielding those items of iterable for which function(item)
 |  is true. If function is None, return the items that are true.
 |  
 |  Methods defined here:
 |  
 |  __getattribute__(self, name, /)
 |      Return getattr(self, name).
 |  
 |  __iter__(self, /)
 |      Implement iter(self).
 |  
 |  __new__(*args, **kwargs) from builtins.type
 |      Create and return a new object.  See help(type) for accurate signature.
 |  
 |  __next__(self, /)
 |      Implement next(self).
 |  
 |  __reduce__(...)
 |      Return state information for pickling.

I like list instead of c because it handles mixed data types better. Adding an additional column to the original poster's question:

#Create an empty data frame
df <- data.frame(hello=character(), goodbye=character(), volume=double())
de <- list(hello="hi", goodbye="bye", volume=3.0)
df = rbind(df,de, stringsAsFactors=FALSE)
de <- list(hello="hola", goodbye="ciao", volume=13.1)
df = rbind(df,de, stringsAsFactors=FALSE)

Note that some additional control is required if the string/factor conversion is important.

Or using the original variables with the solution from MatheusAraujo/Ytsen de Boer:

df[nrow(df) + 1,] = list(hello="hallo",goodbye="auf wiedersehen", volume=20.2)

Note that this solution doesn't work well with the strings unless there is existing data in the dataframe.

You need to check if your machine is 64 bit or 32bit. If your machine is 32 bit then your memory argument should not exceed 4096, even it should be below 4 GB. but if your machine is 64 bit then, install Java 64 bit and provide JAVA_HOME in mvn.bat which point to java 64 bit installation.

This should do it. You were missing a ) and you only need """ not 4 of them. Also you don't need a elif at the end.

ans=True
while ans:
    print("""
    1.Add a Student
    2.Delete a Student
    3.Look Up Student Record
    4.Exit/Quit
    """)
    ans=raw_input("What would you like to do? ")
    if ans=="1":
      print("\nStudent Added")
    elif ans=="2":
      print("\n Student Deleted")
    elif ans=="3":
      print("\n Student Record Found")
    elif ans=="4":
      print("\n Goodbye") 
      ans = None
    else:
       print("\n Not Valid Choice Try again")

Say you have defined your class like this:

    @Data
    @AllArgsConstructor(staticName = "of")
    private class Pair<P,Q> {

        public P first;
        public Q second;
    }

So when you will need to create a new instance, it will need to take the parameters and you will provide it like this as defined in the annotation.

Pair<Integer, String> pair = Pair.of(menuItemId, category);

If you define it like this, you will get the error asked for.

Pair<Integer, String> pair = new Pair(menuItemId, category);

You can use a serialize() function of JQuery:

    var datastring = $("#preview_form").serialize();
        $.ajax({
            type: "POST",
            url: "your url.php",
            data: datastring,
            success: function(data) {
                 alert('Data send');
            }
        });

And read in PHP:

echo $_POST['datastring']['dialog_box_textarea_1'];
echo $_POST['datastring']['radiobutton_1'];
........

And get ***data-**** to tag HTML5 you can see this example:

<div id="texto" data-author="Ricardo Miranda" data-date="2012-06-21">
<h4>Lorem ipsum</h4>
  <p>
    Lorem ipsum dolor sit amet, ius integre eligendi et,
    sea ut expetendis conclusionemque,
    mel at ornatus invenire. His ad moderatius definiebas omittantur,
    liber saepe albucius sea cu.
    Audire tamquam dolores vis ne, mediocrem consulatu eum ex.
    Duo te agam saepe convenire, et fugit iisque his.
 </p>

<script type="text/javascript">
$(function() {
    alert("The text is write " + $('#texto').data('author'));
});

And

<div id="texto" data-author='{"nombre":"Ricardo","apellido":"Miranda"}' data-date="2012-06-21">
   ...
</div>

<script type="text/javascript">
$(function() {
    alert("The text is write " + $('#texto').data('author').apellido + ", " +
        ('#texto').data('author').nombre);
});
</script>

All string functions as lower, upper, strip are returning a string without modifying the original. If you try to modify a string, as you might think well it is an iterable, it will fail.

x = 'hello'
x[0] = 'i' #'str' object does not support item assignment

There is a good reading about the importance of strings being immutable: Why are Python strings immutable? Best practices for using them

Use explicit injection. No other approach will allow you for instance to run tests in parallel in the same JVM.

Patterns that use anything classloader wide like static log binder or messing with environmental thinks like logback.XML are bust when it comes to testing.

Consider the parallelized tests I mention , or consider the case where you want to intercept logging of component A whose construction is hidden behind api B. This latter case is easy to deal with if you are using a dependency injected loggerfactory from the top, but not if you inject Logger as there no seam in this assembly at ILoggerFactory.getLogger.

And its not all about unit testing either. Sometimes we want integration tests to emit logging. Sometimes we don't. Someone's we want some of the integration testing logging to be selectively suppressed, eg for expected errors that would otherwise clutter the CI console and confuse. All easy if you inject ILoggerFactory from the top of your mainline (or whatever di framework you might use)

So...

Either inject a reporter as suggested or adopt a pattern of injecting the ILoggerFactory. By explicit ILoggerFactory injection rather than Logger you can support many access/intercept patterns and parallelization.

You can fix it with this:

if(n == JOptionPane.YES_OPTION)
{
    JOptionPane.showMessageDialog(null, "HELLO");
}
else
{
    JOptionPane.showMessageDialog(null, "GOODBYE");
}

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

Recursive function :

function getElementInsideElement(baseElement, wantedElementID) {
    var elementToReturn;
    for (var i = 0; i < baseElement.childNodes.length; i++) {
        elementToReturn = baseElement.childNodes[i];
        if (elementToReturn.id == wantedElementID) {
            return elementToReturn;
        } else {
            return getElementInsideElement(elementToReturn, wantedElementID);
        }
    }
}

If you have an ES2015 environment (as of this writing: io.js, IE11, Chrome, Firefox, WebKit nightly), then the following will work, and will be fast (viz. O(n)):

function hasDuplicates(array) {
    return (new Set(array)).size !== array.length;
}

If you only need string values in the array, the following will work:

function hasDuplicates(array) {
    var valuesSoFar = Object.create(null);
    for (var i = 0; i < array.length; ++i) {
        var value = array[i];
        if (value in valuesSoFar) {
            return true;
        }
        valuesSoFar[value] = true;
    }
    return false;
}

We use a "hash table" valuesSoFar whose keys are the values we've seen in the array so far. We do a lookup using in to see if that value has been spotted already; if so, we bail out of the loop and return true.

If you need a function that works for more than just string values, the following will work, but isn't as performant; it's O(n²) instead of O(n).

function hasDuplicates(array) {
    var valuesSoFar = [];
    for (var i = 0; i < array.length; ++i) {
        var value = array[i];
        if (valuesSoFar.indexOf(value) !== -1) {
            return true;
        }
        valuesSoFar.push(value);
    }
    return false;
}

The difference is simply that we use an array instead of a hash table for valuesSoFar, since JavaScript "hash tables" (i.e. objects) only have string keys. This means we lose the O(1) lookup time of in, instead getting an O(n) lookup time of indexOf.

I know this is old, but was hunting for the same thing and ended up coming up with another solution which is fairly concise andsimple. Here's my way of finding the next or previous element, taking into account traversal over elements that aren't of the type we're looking for:

var ClosestPrev = $( StartObject ).prevAll( '.selectorClass' ).first();
var ClosestNext = $( StartObject ).nextAll( '.selectorClass' ).first();

I'm not 100% sure of the order that the collection from the nextAll/prevAll functions return, but in my test case, it appears that the array is in the direction expected. Might be helpful if someone could clarify the internals of jquery for that for a strong guarantee of reliability.

You can use fall-through:

switch (pageid)
{
    case "listing-page":
    case "home-page":
        alert("hello");
        break;
    case "details-page":
        alert("goodbye");
        break;
}

Express makes this kind of stuff really intuitive. The syntax looks like below :

var app = require('express').createServer();
app.get("/string", function(req, res) {
    var strings = ["rad", "bla", "ska"]
    var n = Math.floor(Math.random() * strings.length)
    res.send(strings[n])
})
app.listen(8001)

https://expressjs.com

If you're using jQuery on the client side you can do something like this:

$.get("/string", function(string) {
    alert(string)
})

This should do the trick:

for filename in file1.txt file2.txt file3.txt; do
    echo "$filename"
    cat "$filename"
done > output.txt

or to do this for all text files recursively:

find . -type f -name '*.txt' -print | while read filename; do
    echo "$filename"
    cat "$filename"
done > output.txt

Following code worked for me:

public function jsonSerialize()
{
    return get_object_vars($this);
}

You can use System.Uri

Uri url = new Uri("http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye");
string path = String.Format("{0}{1}{2}{3}", url.Scheme, 
    Uri.SchemeDelimiter, url.Authority, url.AbsolutePath);

Or you can use substring

string url = "http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye";
string path = url.Substring(0, url.IndexOf("?"));

EDIT: Modifying the first solution to reflect brillyfresh's suggestion in the comments.

It skips to the start of the next page. (Applies mostly to terminals where the output device is a printer rather than a VDU.)

str.strip() returns a string with leading+trailing whitespace removed, .lstrip and .rstrip for only leading and trailing respectively.

grades.append(lists[i].rstrip('\n').split(','))

Vanilla 1-liner for IE8+:

parent !== child && parent.contains(child);

Here, how it works:

function contains(parent, child) {_x000D_
  return parent !== child && parent.contains(child);_x000D_
}_x000D_
_x000D_
var parentEl = document.querySelector('#parent'),_x000D_
    childEl = document.querySelector('#child')_x000D_
    _x000D_
if (contains(parentEl, childEl)) {_x000D_
  document.querySelector('#result').innerText = 'I confirm, that child is within parent el';_x000D_
}_x000D_
_x000D_
if (!contains(childEl, parentEl)) {_x000D_
  document.querySelector('#result').innerText += ' and parent is not within child';_x000D_
}

<div id="parent">_x000D_
  <div>_x000D_
    <table>_x000D_
      <tr>_x000D_
        <td><span id="child"></span></td>_x000D_
      </tr>_x000D_
    </table>_x000D_
  </div>_x000D_
</div>_x000D_
<div id="result"></div>

A new version for the scenario where the callback will be called by some other function, not your own code, and you want to add additional parameters.

For example, let's pretend that you have a lot of nested calls with success and error callbacks. I will use angular promises for this example but any javascript code with callbacks would be the same for the purpose.

someObject.doSomething(param1, function(result1) {
  console.log("Got result from doSomething: " + result1);
  result.doSomethingElse(param2, function(result2) {
    console.log("Got result from doSomethingElse: " + result2);
  }, function(error2) {
    console.log("Got error from doSomethingElse: " + error2);
  });
}, function(error1) {
  console.log("Got error from doSomething: " + error1);
});

Now you may want to unclutter your code by defining a function to log errors, keeping the origin of the error for debugging purposes. This is how you would proceed to refactor your code:

someObject.doSomething(param1, function (result1) {
  console.log("Got result from doSomething: " + result1);
  result.doSomethingElse(param2, function (result2) {
    console.log("Got result from doSomethingElse: " + result2);
  }, handleError.bind(null, "doSomethingElse"));
}, handleError.bind(null, "doSomething"));

/*
 * Log errors, capturing the error of a callback and prepending an id
 */
var handleError = function (id, error) {
  var id = id || "";
  console.log("Got error from " + id + ": " + error);
};

The calling function will still add the error parameter after your callback function parameters.

i think there should be entry of your your_module.ko in /lib/modules/uname -r/modules.dep and in /lib/modules/uname -r/modules.dep.bin for "modprobe your_module" command to work

Just to clarify - at least from what we found on our side! It is an issue with the setup of the randomizer for Linux in the JDK distribution - and we found it in Java6, not sure about Java7. The syntax for linux for the randomizer is file:///dev/urandom, but the entry in the file is (probably left/copied from Windows) as file:/dev/urandom. So then Java probably falls back on the default, which happens to be /dev/random. And which doesn't work on a headless machine!!!

You can do it in this way

// xyz.h
#ifndef _XYZ_
#define _XYZ_

template <typename XYZTYPE>
class XYZ {
  //Class members declaration
};

#include "xyz.cpp"
#endif

//xyz.cpp
#ifdef _XYZ_
//Class definition goes here

#endif

This has been discussed in Daniweb

Also in FAQ but using C++ export keyword.

Here's what you need:

function mainfunc (){
    window[Array.prototype.shift.call(arguments)].apply(null, arguments);
}

The first argument is used as the function name and all of the remaining ones are used as arguments to the called function...

We're able to use the shift method to return and then delete the first value from the arguments array. Note that we've called it from the Array prototype since, strictly speaking, 'arguments' is not a real array and so doesn't inherit the shift method like a regular array would.

You can also call the shift method like this:

[].shift.call(arguments);

I will post right solution at the bottom of the page in case someone is brave (or despaired enough) to read to this point.

Here is gitHub repo for those, who don't want to read all that text: resizableTextView

This works with iOs7 (and I do believe it will work with iOs8) and with autolayout. You don't need magic numbers, disable layout and stuff like that. Short and elegant solution.

I think, that all constraint-related code should go to updateConstraints method. So, let's make our own ResizableTextView.

The first problem we meet here is that don't know real content size before viewDidLoad method. We can take long and buggy road and calculate it based on font size, line breaks, etc. But we need robust solution, so we'll do:

CGSize contentSize = [self sizeThatFits:CGSizeMake(self.frame.size.width, FLT_MAX)];

So now we know real contentSize no matter where we are: before or after viewDidLoad. Now add height constraint on textView (via storyboard or code, no matter how). We'll adjust that value with our contentSize.height:

[self.constraints enumerateObjectsUsingBlock:^(NSLayoutConstraint *constraint, NSUInteger idx, BOOL *stop) {
    if (constraint.firstAttribute == NSLayoutAttributeHeight) {
        constraint.constant = contentSize.height;
        *stop = YES;
    }
}];

The last thing to do is to tell superclass to updateConstraints.

[super updateConstraints];

Now our class looks like:

ResizableTextView.m

- (void) updateConstraints {
    CGSize contentSize = [self sizeThatFits:CGSizeMake(self.frame.size.width, FLT_MAX)];

    [self.constraints enumerateObjectsUsingBlock:^(NSLayoutConstraint *constraint, NSUInteger idx, BOOL *stop) {
        if (constraint.firstAttribute == NSLayoutAttributeHeight) {
            constraint.constant = contentSize.height;
            *stop = YES;
        }
    }];

    [super updateConstraints];
}

Pretty and clean, right? And you don't have to deal with that code in your controllers!

But wait! Y NO ANIMATION!

You can easily animate changes to make textView stretch smoothly. Here is an example:

    [self.view layoutIfNeeded];
    // do your own text change here.
    self.infoTextView.text = [NSString stringWithFormat:@"%@, %@", self.infoTextView.text, self.infoTextView.text];
    [self.infoTextView setNeedsUpdateConstraints];
    [self.infoTextView updateConstraintsIfNeeded];
    [UIView animateWithDuration:1 delay:0 options:UIViewAnimationOptionLayoutSubviews animations:^{
        [self.view layoutIfNeeded];
    } completion:nil];

Take a look at this post on Java Ranch:

http://www.coderanch.com/t/300287/JDBC/java/Io-Exception-Network-Adapter-could

"The solution for my "Io exception: The Network Adapter could not establish the connection" exception was to replace the IP of the database server to the DNS name."

Maybe specifying a width would work. When you position:absolute an element, it's width will shrink to the contents I believe.

import the HttpClientModule in your app.module.ts

import {HttpClientModule} from '@angular/common/http';

...
@NgModule({
...
  imports: [
    //other content,
    HttpClientModule
  ]
})

The console is printing the representation, not the string itself.

If you prefix with print, you'll get what you expect.

See this question for details about the difference between a string and the string's representation. Super-simplified, the representation is what you'd type in source code to get that string.

On windows, nearly all AMPP (Apache,MySQL,PHP,PHPmyAdmin) packages don't include a mail server (but nearly all naked linuxes do have!). So, when using PHP under windows, you need to setup a mail server!

Imo the best and most simple tool ist this: http://smtp4dev.codeplex.com/

SMTP4Dev is a simple one-file mail server tool that does collect the mails it send (so it does not really sends mail, it just keeps them for development). Perfect tool.

unfortunately this option was removed in most browsers, so it is not possible to disable the password hint, until today I did not find a good solution to work around this problem, what we have left now is to hope that one day this option will come back.

Please use count function, Here is a example how to count array in a element

$cars = array("Volvo","BMW","Toyota");
echo count($cars);

The count() function returns the number of elements in an array.

The sizeof() function returns the number of elements in an array.

The sizeof() function is an alias of the count() function.

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

How about using

if (empty($result['column']))

JSONArray successObject=new JSONArray();
JSONObject dataObject=new JSONObject();
successObject.put(dataObject.toString());

This works for me.

I also had the same problem. Then I installed the zlib, still the problem remained the same. Then I added the following lines in my .bashrc and it worked. You should replace the path with your zlib installation path. (I didn't have root privileges).

export PATH =$PATH:$HOME/Softwares/library/Zlib/zlib-1.2.11/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/Softwares/library/Zlib/zlib-1.2.11/lib/
export LIBRARY_PATH=$LIBRARY_PATH:$HOME/Softwares/library/Zlib/zlib-1.2.11/lib/
export C_INCLUDE_PATH=$HOME/Softwares/library/Zlib/zlib-1.2.11/include/
export CPLUS_INCLUDE_PATH=$HOME/Softwares/library/Zlib/zlib-1.2.11/include/
export PKG_CONFIG_PATH=$HOME/Softwares/library/Zlib/zlib-1.2.11/lib/pkgconfig

Lot of very detailed answers here but I don't think you are answering the right questions. As I understand the question, there are two concerns:

1. How to I score a multiclass problem?
2. How do I deal with unbalanced data?

1.

You can use most of the scoring functions in scikit-learn with both multiclass problem as with single class problems. Ex.:

from sklearn.metrics import precision_recall_fscore_support as score

predicted = [1,2,3,4,5,1,2,1,1,4,5] 
y_test = [1,2,3,4,5,1,2,1,1,4,1]

precision, recall, fscore, support = score(y_test, predicted)

print('precision: {}'.format(precision))
print('recall: {}'.format(recall))
print('fscore: {}'.format(fscore))
print('support: {}'.format(support))

This way you end up with tangible and interpretable numbers for each of the classes.

| Label | Precision | Recall | FScore | Support |
|-------|-----------|--------|--------|---------|
| 1     | 94%       | 83%    | 0.88   | 204     |
| 2     | 71%       | 50%    | 0.54   | 127     |
| ...   | ...       | ...    | ...    | ...     |
| 4     | 80%       | 98%    | 0.89   | 838     |
| 5     | 93%       | 81%    | 0.91   | 1190    |

Then...

2.

... you can tell if the unbalanced data is even a problem. If the scoring for the less represented classes (class 1 and 2) are lower than for the classes with more training samples (class 4 and 5) then you know that the unbalanced data is in fact a problem, and you can act accordingly, as described in some of the other answers in this thread. However, if the same class distribution is present in the data you want to predict on, your unbalanced training data is a good representative of the data, and hence, the unbalance is a good thing.

Open cmd and go In Directory where file is saved. Then, For compile, g++ FileName. cpp Or gcc FileName. cpp

For Run, FileName. exe

This Is For Compile & Run Program.

Make sure, gcc compiler installed in PC or Laptop. And also path variable must be set.

For Android 10 there is background restrictions.

For android 10 and all version of android follow this steps to start an app after a restart or turn on mobile

Add this two permission in Android Manifest

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

Add this in your application tag

<receiver
        android:name=".BootReciever"
        android:enabled="true"
        android:exported="true"
        android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
</receiver>

Add this class to start activity when boot up

public class BootReciever extends BroadcastReceiver {

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

    if (Objects.equals(intent.getAction(), Intent.ACTION_BOOT_COMPLETED)) {
        Intent i = new Intent(context, SplashActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
 }}

We need Draw overlay permission for android 10

so add this in your first activity

 private fun requestPermission() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (!Settings.canDrawOverlays(this)) {
            val intent = Intent(
                Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
                Uri.parse("package:" + this.packageName)
            )
            startActivityForResult(intent, 232)
        } else {
            //Permission Granted-System will work
        }
    }
}

Follow the steps given here

http://www.javaandme.com/

after setting variable, just navigate to your java file directory in your cmd and type javac "xyx.java"

or if you don't navigate to the directory, then simply specify the full path of java file

javac "/xyz.java"

The catch is you must create a dummy Facebook application just to have an app_id. Note that your Facebook application doesn't have to do ANYTHING at all. Just be sure that it is properly configured, and you should be all set.

Try this function:

=SUBTOTAL(3, B$2:B2)

You can find more details in this blog entry.

Performance-wise it's the same as a named method. The big problem is when you do the following:

MyButton.Click -= (o, i) => 
{ 
    //snip 
} 

It will probably try to remove a different lambda, leaving the original one there. So the lesson is that it's fine unless you also want to be able to remove the handler.

A rect can't contain a text element. Instead transform a g element with the location of text and rectangle, then append both the rectangle and the text to it:

var bar = chart.selectAll("g")
    .data(data)
  .enter().append("g")
    .attr("transform", function(d, i) { return "translate(0," + i * barHeight + ")"; });

bar.append("rect")
    .attr("width", x)
    .attr("height", barHeight - 1);

bar.append("text")
    .attr("x", function(d) { return x(d) - 3; })
    .attr("y", barHeight / 2)
    .attr("dy", ".35em")
    .text(function(d) { return d; });

Multi-line labels are also a little tricky, you might want to check out this wrap function.

Actually, For the first build, please do it with Xcode and then do the following way:

1. brew install ios-deploy
2. npx react-native run-ios --device

The second command will run the app on the first connected device.

FYI you can also get this error if EF Migrations tries to run with no Db configured, for example in a Test Project.

Chased this for hours before I figured out that it was erroring on a query, but, not because of the query but because it was when Migrations kicked in to try to create the Db.

Instead of using .get, using like this should be ok for lists. Just a usage difference.

>>> l = [1]
>>> l[10] if 10 < len(l) else 'fail'
'fail'

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

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

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

Option Explicit
Private cancelling As Boolean

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

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

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

Private Sub OkButton_Click()
    Me.Hide
End Sub

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

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

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

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

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

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

This is one of those things that can be difficult to search for if you don't already know where to look.

[ is actually a command, not part of the bash shell syntax as you might expect. It happens to be a Bash built-in command, so it's documented in the Bash manual.

There's also an external command that does the same thing; on many systems, it's provided by the GNU Coreutils package.

[ is equivalent to the test command, except that [ requires ] as its last argument, and test does not.

Assuming the bash documentation is installed on your system, if you type info bash and search for 'test' or '[' (the apostrophes are part of the search), you'll find the documentation for the [ command, also known as the test command. If you use man bash instead of info bash, search for ^ *test (the word test at the beginning of a line, following some number of spaces).

Following the reference to "Bash Conditional Expressions" will lead you to the description of -ne, which is the numeric inequality operator ("ne" stands for "not equal). By contrast, != is the string inequality operator.

You can also find bash documentation on the web.

• Bash reference
• Bourne shell builtins (including test and [)
• Bash Conditional Expressions -- (Scroll to the bottom; -ne is under "arg1 OP arg2")
• POSIX documentation for test

The official definition of the test command is the POSIX standard (to which the bash implementation should conform reasonably well, perhaps with some extensions).

What's a "block scheme"?

If I were drawing it, I might draw a box with "for each x in y" written in it.

If you're drawing a flowchart, there's always a loop with a decision box.

Nassi-Schneiderman diagrams have a loop construct you could use.

What you'll see sometimes is the following:

class Abstract1( object ):
    """Some description that tells you it's abstract,
    often listing the methods you're expected to supply."""
    def aMethod( self ):
        raise NotImplementedError( "Should have implemented this" )

Because Python doesn't have (and doesn't need) a formal Interface contract, the Java-style distinction between abstraction and interface doesn't exist. If someone goes through the effort to define a formal interface, it will also be an abstract class. The only differences would be in the stated intent in the docstring.

And the difference between abstract and interface is a hairsplitting thing when you have duck typing.

Java uses interfaces because it doesn't have multiple inheritance.

Because Python has multiple inheritance, you may also see something like this

class SomeAbstraction( object ):
    pass # lots of stuff - but missing something

class Mixin1( object ):
    def something( self ):
        pass # one implementation

class Mixin2( object ):
    def something( self ):
        pass # another

class Concrete1( SomeAbstraction, Mixin1 ):
    pass

class Concrete2( SomeAbstraction, Mixin2 ):
    pass

This uses a kind of abstract superclass with mixins to create concrete subclasses that are disjoint.

I just wanted to add my opinion about this.

I think we can just use like this:

var haystack = 'hello world';
var needle = 'he';

if (haystack.indexOf(needle) == 0) {
  // Code if string starts with this substring
}

You type diskpart, list disk and check disks for boot.
Ex:

dispart 
list disk 
select disk 0 
detail disk

The disk with Boot volume is disk with windows installed:

EDIT : In your activity add this:

yourView.startAnimation(AnimationUtils.loadAnimation(co??ntext, R.anim.yourAnimation));

There's a bit more to it than just local vs global. Global variables created with var are different than those created without. Consider this:

var foo = 1; // declared properly
bar = 2; // implied global
window.baz = 3; // global via window object

Based on the answers so far, these global variables, foo, bar, and baz are all equivalent. This is not the case. Global variables made with var are (correctly) assigned the internal [[DontDelete]] property, such that they cannot be deleted.

delete foo; // false
delete bar; // true
delete baz; // true

foo; // 1
bar; // ReferenceError
baz; // ReferenceError

This is why you should always use var, even for global variables.

Try this out.

I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).

If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::.

Something along these lines:

create view view1
as 
select table1.col1,table2.col1,table3.col3
from table1 
inner join
table2 
inner join 
table3
on 
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;

Notice the varchar typecasting on the table1.col4.

Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.

Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).

Seems like you use Angular 4.3 version, I also faced with same problem. Use Angular 4.0.1 and post with code by @trichetricheand and it will work. I am also not sure how to solve it on Angular 4.3 :S

you cant do this. Use a custom popup. Something like with the help of jQuery UI or jQuery BOXY.

for jQuery UI http://jqueryui.com/demos/dialog/

Use subprocess.Popen:

import subprocess
process = subprocess.Popen(['ls', '-a'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = process.communicate()
print(out)

Note that communicate blocks until the process terminates. You could use process.stdout.readline() if you need the output before it terminates. For more information see the documentation.

I used this script on windows powershell:

ForEach ($f in get-ChildItem *.sql) { type "$f" >> all.sql }

Why the prohibition "I don't want to use any looping"? That's the most obvious solution. When given the chance to be obvious, take it!

Note that calls like arr.Contains(...) are still going to loop, it just won't be you who has written the loop.

Have you considered an alternate representation that's more amenable to searching?

• A good Set implementation would perform well. (HashSet, TreeSet or the local equivalent).
• If you can be sure that arr is sorted, you could use binary search (which would need to recurse or loop, but not as often as a straight linear search).

Arrays.asList(array)

Arrays uses new ArrayList(array). But this is not the java.util.ArrayList. It's very similar though. Note that this constructor takes the array and places it as the backing array of the list. So it is O(1).

In case you already have the list created, Collections.addAll(list, array), but that's less efficient.

Update: Thus your Collections.addAll(list, array) becomes a good option. A wrapper of it is guava's Lists.newArrayList(array).

Return a tuple:

func getTime() -> (Int, Int, Int) {
    ...
    return ( hour, minute, second)
}

Then it's invoked as:

let (hour, minute, second) = getTime()

or:

let time = getTime()
println("hour: \(time.0)")

Find end position of file:

f = open("file.txt","r")
f.seek(0,2) #Jumps to the end
f.tell()    #Give you the end location (characters from start)
f.seek(0)   #Jump to the beginning of the file again

Then you can to:

if line == '' and f.tell() == endLocation:
   break

on your activity(behind the drawer):

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar,
               R.string.navigation_drawer_open,
               R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);
    navigationView.setCheckedItem(R.id.nav_portfolio);
    onNavigationItemSelected(navigationView.getMenu().getItem(0));
}

and

@Override
public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    int id = item.getItemId();

    Fragment fragment = null;

    if (id == R.id.nav_test1) {
        fragment = new Test1Fragment();
        displaySelectedFragment(fragment);
    } else if (id == R.id.nav_test2) {
        fragment = new Test2Fragment();
        displaySelectedFragment(fragment);
    }

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

and in your menu:

<group android:checkableBehavior="single">

    <item
        android:id="@+id/nav_test1"
        android:title="@string/test1" />

    <item
        android:id="@+id/nav_test2"
        android:title="@string/test2" />

  </group>

so first menu is highlight and show as default menu.

The same problem happened to me when I use distcc to make my c++ project; Finally I solved it with export CXX="distcc g++".

have you tried something like this:

if [ $# -eq 0 ] || [ $# -gt 1 ] 
then
 echo "$#"
fi

You can do this simply like this

$('#image_id').click(function() {
  $("#some_id iframe").attr('src', $("#some_id iframe", parent).attr('src') + '?autoplay=1'); 
});

where image_id is your image id you are clicking and some_id is id of div in which iframe is also you can use iframe id directly.

I found a different solution to this issue. Apparently my IIS 7 did not have 32bit mode enabled in my Application Pool by default.

To enable 32bit mode, open IIS and select your Application Pool. Mine was named "ASP.NET v4.0".
Right click, go to "Advanced Settings" and change the section named: "Enabled 32-bit Applications" to true.

Restart your web server and try again.

I found the fix from this blog reference: http://darrell.mozingo.net/2009/01/17/running-iis-7-in-32-bit-mode/

Additionally, you can change the settings on Visual Studio. In my case, I went to Tools > Options > Projects and Solutions > Web Projects and checked Use the 64 bit version of IIS Express for web sites and projects - This was on VS Pro 2015. Nothing else fixed it but this.

try this

    $('#div_id').animate({scrollTop:0}, '500', 'swing');

Steps (1) Just Select your range, rows or column or array , (2) Press ctrl+H , (3 a) then in the find type a space (3 b) in the replace do not enter anything, (4)then just click on replace all..... you are done.

install sqlescapy package:

pip install sqlescapy

then you can escape variables in you raw query

from sqlescapy import sqlescape

query = """
    SELECT * FROM "bar_table" WHERE id='%s'
""" % sqlescape(user_input)

You can use -v option multiple times in docker run command to mount multiple directory in container:

docker run -t -i \
  -v '/on/my/host/test1:/on/the/container/test1' \
  -v '/on/my/host/test2:/on/the/container/test2' \
  ubuntu /bin/bash

If you're really, absolutely positively sure that the NSURL is a file url, i.e. [url isFileURL] is guaranteed to return true in your case, then you can simply use:

[UIImage imageWithContentsOfFile:url.path]

Use requests library to GET, POST, PUT or DELETE by hitting a REST API endpoint. Pass the rest api endpoint url in url, payload(dict) in data and header/metadata in headers

import requests, json

url = "bugs.python.org"

payload = {"number": 12524, 
           "type": "issue", 
           "action": "show"}

header = {"Content-type": "application/x-www-form-urlencoded",
          "Accept": "text/plain"} 

response_decoded_json = requests.post(url, data=payload, headers=header)
response_json = response_decoded_json.json()

print response_json

LIMIT 1 is what you want. Just keep in mind this returns the first record in the result set regardless of order (unless you specify an order clause in an outer query).

The R packages dplyr and sf import the operator %>% from the R package magrittr.

Help is available by using the following command:

?'%>%'

Of course the package must be loaded before by using e.g.

library(sf)

The documentation of the magrittr forward-pipe operator gives a good example: When functions require only one argument, x %>% f is equivalent to f(x)

If you just need to try something out quickly, here's a quick and dirty solution. Use single quotes for the attribute value:

<parameter name='Quote = " '>

Go to your git Directory then type the following command: rm -rf <Directory Name>

After Deleting the directory commit the changes by: git commit -m "Your Commit Message"

Then Simply push the changes on remote GIT directory: git push origin <Branch name>

This is old but it is still useful, Fully tested with QT5.3.

Be carreful, example concerning the ressources path :

In my case I created a ressources directory named "Ressources" in the source directory project.

The folder "ressources" contain pictures and icons.Then I added a prefix "Images" in Qt So the pixmap path become:

QPixmap pixmap(":/images/Ressources/icone_pdf.png");

Finding Merging Errors in AndroidManifest.xml

Click on Merged Manifest in AndroidManifest.xml

You can view manifest merging error in right column. It may help to solve this problem.

You can only use aggregates for comparison in the HAVING clause:

GROUP BY ...
  HAVING SUM(cash) > 500

The HAVING clause requires you to define a GROUP BY clause.

To get the first row where the sum of all the previous cash is greater than a certain value, use:

SELECT y.id, y.cash
  FROM (SELECT t.id,
               t.cash,
               (SELECT SUM(x.cash)
                  FROM TABLE x
                 WHERE x.id <= t.id) AS running_total
         FROM TABLE t
     ORDER BY t.id) y
 WHERE y.running_total > 500
ORDER BY y.id
   LIMIT 1

Because the aggregate function occurs in a subquery, the column alias for it can be referenced in the WHERE clause.

I made this in my code to do that

note: I am a beginner.

It is my jsp code.

<%
java.sql.Connection Conn = DBconnector.SetDBConnection(); /* make connector as you make in your code */
Statement st = null;
ResultSet rs = null;
st = Conn.createStatement();
rs = st.executeQuery("select * from department"); %>

    <td> 
        Student Major  : <select name ="Major">
        <%while(rs.next()){ %>
        <option value="<%=rs.getString(1)%>"><%=rs.getString(1)%></option>
                        <%}%>           
                         </select>

Another solution, first considering the case where you don't care about collision location. Note that this particular function is built assuming vector input for xB and yB but can easily be modified if that is not the case. Variable names are defined at the start of the function

#Line segment points (A0, Af) defined by xA0, yA0, xAf, yAf; circle center denoted by xB, yB; rB=radius of circle, rA = radius of point (set to zero for your application)
def staticCollision_f(xA0, yA0, xAf, yAf, rA, xB, yB, rB): #note potential speed up here by casting all variables to same type and/or using Cython
    
    #Build equations of a line for linear agents (convert y = mx + b to ax + by + c = 0 means that a = -m, b = 1, c = -b
    m_v = (yAf - yA0) / (xAf - xA0)
    b_v = yAf - m_v * xAf
    rEff = rA + rB #radii are added since we are considering the agent path as a thin line

    #Check if points (circles) are within line segment (find center of line segment and check if circle is within radius of this point)
    segmentMask = np.sqrt( (yB - (yA0+yAf)/2)**2 + (xB - (xA0+xAf)/2)**2 ) < np.sqrt( (yAf - yA0)**2 + (xAf - xA0)**2 ) / 2 + rEff

    #Calculate perpendicular distance between line and a point
    dist_v = np.abs(-m_v * xB + yB - b_v) / np.sqrt(m_v**2 + 1)
    collisionMask = (dist_v < rEff) & segmentMask

    #return True if collision is detected
    return collisionMask, collisionMask.any()

If you need the location of the collision, you can use the approach detailed on this site, and set the velocity of one of the agents to zero. This approach works well with vector inputs as well: http://twobitcoder.blogspot.com/2010/04/circle-collision-detection.html

Don't try commiting / adding files. Just run the following 2 commands (:

    git remote add origin http://xyzremotedir/xyzgitproject.git

Combination of @[macbirdie] and @[Adrian Borchardt] answer. Which proves to be very useful in production environment (not messing up previously existing warning, especially during cross-platform compile)

From the use of 8080 I'm assuming you are using a tomcat servlet container to serve your rest api. If this is the case you can also consider to have your webserver proxy the requests to the servlet container.

With apache you would typically use mod_jk (although there are other alternatives) to serve the api trough the web server behind port 80 instead of 8080 which would solve the cross domain issue.

This is common practice, have the 'static' content in the webserver and dynamic content in the container, but both served from behind the same domain.

The url for the rest api would be http://localhost/restws/json/product/get

Here a description on how to use mod_jk to connect apache to tomcat: http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html

SELECT column1 FROM table WHERE column1 not like '%[0-9]%'

Removing the '^' did it for me. I'm looking at a varchar field and when I included the ^ it excluded all of my non-numerics which is exactly what I didn't want. So, by removing ^ I only got non-numeric values back.

Probably you are trying to access the excel with the index 0, please note that Excel rows/columns start from 1.

put ur js code under the form html or use $(document).ready(function(){}) and try this.

$('#inline_content input[type="radio"]').click(function(){
                if($(this).val() == "walk_in"){
                    alert('ok');
                }
});

The SettingWithCopyWarning was created to flag potentially confusing "chained" assignments, such as the following, which does not always work as expected, particularly when the first selection returns a copy. [see GH5390 and GH5597 for background discussion.]

df[df['A'] > 2]['B'] = new_val  # new_val not set in df

The warning offers a suggestion to rewrite as follows:

df.loc[df['A'] > 2, 'B'] = new_val

However, this doesn't fit your usage, which is equivalent to:

df = df[df['A'] > 2]
df['B'] = new_val

While it's clear that you don't care about writes making it back to the original frame (since you are overwriting the reference to it), unfortunately this pattern cannot be differentiated from the first chained assignment example. Hence the (false positive) warning. The potential for false positives is addressed in the docs on indexing, if you'd like to read further. You can safely disable this new warning with the following assignment.

import pandas as pd
pd.options.mode.chained_assignment = None  # default='warn'

In my case, the argument type was different in the header file and .cpp file. In the header file the type was std::wstring and in the .cpp file it was LPCWSTR.

I tried using Adam B's answer, however, it didn't work for me. Instead, I found the following workaround for adding legends to pointplots.

import matplotlib.patches as mpatches
red_patch = mpatches.Patch(color='#bb3f3f', label='Label1')
black_patch = mpatches.Patch(color='#000000', label='Label2')

In the pointplots, the color can be specified as mentioned in previous answers. Once these patches corresponding to the different plots are set up,

plt.legend(handles=[red_patch, black_patch])

And the legend ought to appear in the pointplot.

The important thing to note here is that the mime type is not the same as the file extension. Sometimes, however, they have the same value.

https://www.iana.org/assignments/media-types/media-types.xhtml includes a list of registered Mime types, though there is nothing stopping you from making up your own, as long as you are at both the sending and the receiving end. Here is where Microsoft comes in to the picture.

Where there is a lot of confusion is the fact that operating systems have their own way of identifying file types by using the tail end of the file name, referred to as the extension. In modern operating systems, the whole name is one long string, but in more primitive operating systems, it is treated as a separate attribute.

The OS which caused the confusion is MSDOS, which had limited the extension to 3 characters. This limitation is inherited to this day in devices, such as SD cards, which still store data in the same way.

One side effect of this limitation is that some file extensions, such as .gif match their Mime Type, image/gif, while others are compromised. This includes image/jpeg whose extension is shortened to .jpg. Even in modern Windows, where the limitation is lifted, Microsoft never let the past go, and so the file extension is still the shortened version.

Given that that:

1. File Extensions are not File Types
2. Historically, some operating systems had serious file name limitations
3. Some operating systems will just go ahead and make up their own rules

The short answer is:

• Technically, there is no such thing as image/jpg, so the answer is that it is not the same as image/jpeg
• That won’t stop some operating systems and software from treating it as if it is the same

While we’re at it …

Legacy versions of Internet Explorer took the liberty of uploading jpeg files with the Mime Type of image/pjpeg, which, of course, just means more work for everybody else. They also uploaded png files as image/x-png.

When you use strace (on Linux) to run your binary, it will output the returns from system calls and what the error number means. This may sometimes be useful to you.

There's a drop down just above the code window:

It's called Navigation bar and contains three drop downs: first drop down contains project, second type and third members (methods).

You can use the shortcut Ctrl + F2 (move focus to the project drop down) and press Tab twice (move focus to the third drop down) to focus it, down arrow will expand the list.

Full size image

You can achieve it by code also, In you Global.asax file in Session_Start event write response.redirect to your start page like following.

void Session_Start(object sender, EventArgs e)
        {
            // Code that runs when a new session is started

            Response.Redirect("~/Index.aspx");

        }

You can get redirect page name from database or any other storage to change the application start page while application is running no need to edit web.config or change any IIS settings

In that case you don't want to insert size and color inside an array, but into an object

var options = { 
    'size': size,
    'color': color
  };

Afterwards you can access the sets of keys by

var keys = Object.keys( options );

A quick benchmark:

import collections
import itertools

def count_iter_items(iterable):
    counter = itertools.count()
    collections.deque(itertools.izip(iterable, counter), maxlen=0)
    return next(counter)

def count_lencheck(iterable):
    if hasattr(iterable, '__len__'):
        return len(iterable)

    d = collections.deque(enumerate(iterable, 1), maxlen=1)
    return d[0][0] if d else 0

def count_sum(iterable):           
    return sum(1 for _ in iterable)

iter = lambda y: (x for x in xrange(y))

%timeit count_iter_items(iter(1000))
%timeit count_lencheck(iter(1000))
%timeit count_sum(iter(1000))

The results:

10000 loops, best of 3: 37.2 µs per loop
10000 loops, best of 3: 47.6 µs per loop
10000 loops, best of 3: 61 µs per loop

I.e. the simple count_iter_items is the way to go.

Adjusting this for python3:

61.9 µs ± 275 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
74.4 µs ± 190 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
82.6 µs ± 164 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)

This should do the job:

re.match(r"[^[]*\[([^]]*)\]", yourstring).groups()[0]

This can achieve using two SQL functions- SUBSTRING and CHARINDEX

You can read strings to a variable as shown in the above answers, or can add it to a SELECT statement as below:

SELECT SUBSTRING('Net Operating Loss - 2007' ,0, CHARINDEX('-','Net Operating Loss - 2007'))

You can try this as well for numeric input with length restriction

<input type="tel" maxlength="3" />

Yes, but the syntax is different than what you have

SELECT
    <fields>
FROM
    <table1>
    LEFT JOIN <table2>
        ON <criteria for join>
        AND <other criteria for join>
    LEFT JOIN <table3> 
        ON <criteria for join>
        AND <other criteria for join>

In addition to the locations listed above, the OS X version of Perl also has two more ways:

6. The /Library/Perl/x.xx/AppendToPath file. Paths listed in this file are appended to @INC at runtime.

7. The /Library/Perl/x.xx/PrependToPath file. Paths listed in this file are prepended to @INC at runtime.

The expression df1$id %in% idNums1 produces a logical vector. To negate it, you need to negate the whole vector:

!(df1$id %in% idNums1)

I actually have a similar problem. I have a page with multiple radio buttons; each button will set the title and description meta tags of the page, via JavaScript upon change.

For example, if users select the first button, the meta tags will say:

<meta name="title" content="First Title">
<meta name="description" content="First Description">

If the user select the second button, this changes the meta tags to:

<meta name="title" content="Second Title">
<meta name="description" content="Second Description">

... and so on. I have confirmed that the code is working fine via Firebug (i.e. I can see that those two tags were properly changed).

Apparently, Facebook Share only pulls in the title and description meta tags that are available upon page load. The changes to those two tags post page load are completely ignored.

Does anybody have any ideas on how to solve this? That is, to force Facebook to get the latest values that are change after the page loads.

You can add the option to rollback your change immediately.

This answer has 20 upvotes now, but it is not intended as an endorsement of std::valarray.

In my experience, time is better spent installing and learning to use a full-fledged math library such as Eigen. Valarray has fewer features than the competition, but it isn't more efficient or particularly easier to use.

If you only need a little bit of linear algebra, and you are dead-set against adding anything to your toolchain, then maybe valarray would fit. But, being stuck unable to express the mathematically correct solution to your problem is a very bad position to be in. Math is relentless and unforgiving. Use the right tool for the job.

The standard library provides std::valarray<double>. std::vector<>, suggested by a few others here, is intended as a general-purpose container for objects. valarray, lesser known because it is more specialized (not using "specialized" as the C++ term), has several advantages:

• It does not allocate extra space. A vector rounds up to the nearest power of two when allocating, so you can resize it without reallocating every time. (You can still resize a valarray; it's just still as expensive as realloc().)
• You may slice it to access rows and columns easily.
• Arithmetic operators work as you would expect.

Of course, the advantage over using C is that you don't need to manage memory. The dimensions can reside on the stack, or in a slice object.

std::valarray<double> matrix( row * col ); // no more, no less, than a matrix
matrix[ std::slice( 2, col, row ) ] = pi; // set third column to pi
matrix[ std::slice( 3*row, row, 1 ) ] = e; // set fourth row to e

NO NEED FOR MULTIDEX, I REPEAT, NO NEEED FOR MULTIDEX

Let me elaborate: Multidex is basically a tool that comes with Android, and if you set it to true, apps with >64,000 methods are able to compile using a slightly altered build process. However you only need to use multidex if your error looks like this:

trouble writing output: Too many field references: 131000; max is 65536. You may try using --multi-dex option.

or like this

Conversion to Dalvik format failed: Unable to execute dex: method ID not in [0, 0xffff]: 65536

But that is not the case here! The problem here (for me atleast) is being caused by your build.gradle file's dependencies.

THE SOLUTION: Utilize specific dependencies—don't just import an entire section of dependencies!

For example, if you need the Play Services dependency for location, only import it for location.

DO:

compile 'com.google.android.gms:play-services-location:11.0.4'

DON'T:

compile 'com.google.android.gms:play-services'

Another issue that could be causing this may be some sort of external library you are using, that is referencing a prior version of your dependency. Follow these steps in that case:

1. Go to SDK manager, and install any updates to your dependencies
2. Make sure that your build.gradle file shows the latest version. To get the latest version, use this link: https://developers.google.com/android/guides/setup
3. Edit your library (or install an updated version if that exists), to reference the latest version

I know this question is old, but I need to get this answer out there, because using multidex for no reason could potentially cause ANR's for your app! ONLY use multidex if you're sure you need it, and you understand what it is.

I myself spent hours trying to resolve this issue without multidex, and I just wanted to share my findings—hope this helps

I know this seems like noob answer but I'm putting it here so that it can help others in the future.

Suppose you are building a table with a foreach loop. And at the same time adding checkboxes at the end.

<!-- Begin Loop-->
<tr>
 <td><?=$criteria?></td>
 <td><?=$indicator?></td>
 <td><?=$target?></td>
 <td>
   <div class="form-check">
    <input type="checkbox" class="form-check-input" name="active" value="<?=$id?>" <?=$status?'checked':''?>> 
<!-- mark as 'checked' if checkbox was selected on a previous save -->
   </div>
 </td>
</tr>
<!-- End of Loop -->

You place a button below the table with a hidden input:

<form method="post" action="/goalobj-review" id="goalobj">

 <!-- we retrieve saved checkboxes & concatenate them into a string separated by commas.i.e. $saved_data = "1,2,3"; -->

 <input type="hidden" name="result" id="selected" value="<?= $saved_data ?>>
 <button type="submit" class="btn btn-info" form="goalobj">Submit Changes</button>
</form>

You can write your script like so:

<script type="text/javascript">
    var checkboxes = document.getElementsByClassName('form-check-input');
    var i;
    var tid = setInterval(function () {
        if (document.readyState !== "complete") {
            return;
        }
        clearInterval(tid);
    for(i=0;i<checkboxes.length;i++){
        checkboxes[i].addEventListener('click',checkBoxValue);
    }
    },100);

    function checkBoxValue(event) {
        var selected = document.querySelector("input[id=selected]");
        var result = 0;
        if(this.checked) {

            if(selected.value.length > 0) {
                result = selected.value + "," + this.value;
                document.querySelector("input[id=selected]").value = result;
            } else {
                result = this.value;
                document.querySelector("input[id=selected]").value = result;
            }
        }
        if(! this.checked) { 

// trigger if unchecked. if checkbox is marked as 'checked' from a previous saved is deselected, this will also remove its corresponding value from our hidden input.

            var compact = selected.value.split(","); // split string into array
            var index = compact.indexOf(this.value); // return index of our selected checkbox
            compact.splice(index,1); // removes 1 item at specified index
            var newValue = compact.join(",") // returns a new string
            document.querySelector("input[id=selected]").value = newValue;
        }

    }
</script>

The ids of your checkboxes will be submitted as a string "1,2" within the result variable. You can then break it up at the controller level however you want.

First, you need to compile your code with appropriate flags, enabling debug into code.

$ gcc -Wall -g -ggdb -o ex1 ex1.c

then just run you code with your favourite debugger

$ gdb ./ex1

show me the code.

(gdb) list

6       printf("%d\n", i);
7   
8     return 0;
9   }

break on lines 5 and looks if i == 5.

Have you tried git push? gitref.org has a nice section dealing with remote repositories.

You can also get help from the command line using the --help option. For example:

% git push --help
GIT-PUSH(1)                             Git Manual                             GIT-PUSH(1)



NAME
       git-push - Update remote refs along with associated objects

SYNOPSIS
       git push [--all | --mirror | --tags] [-n | --dry-run] [--receive-pack=<git-receive-pack>]
                  [--repo=<repository>] [-f | --force] [-v | --verbose] [-u | --set-upstream]
                  [<repository> [<refspec>...]]

Though it is perfectly possible to use a recursive regex as MizardX has posted, for this kind of things it is much more useful a parser. Regexes were originally intended to be used with regular languages, being recursive or having balancing groups is just a patch.

The language that defines valid regexes is actually a context free grammar, and you should use an appropriate parser for handling it. Here is an example for a university project for parsing simple regexes (without most constructs). It uses JavaCC. And yes, comments are in Spanish, though method names are pretty self-explanatory.

Just update your eclipse.ini file (you can find it in the root-directory of eclipse) by this:

-vm
path/javaw.exe

for example:

-vm 
C:/Program Files/Java/jdk1.7.0_09/jre/bin/javaw.exe

File mode, write and binary. Since you are writing a .jpg file, it looks fine.

But if you supposed to read that jpg file you need to use 'rb'

More info

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files.

Is it good to use async action everywhere in ASP.NET MVC?

It's good to do so wherever you can use an async method especially when you have performance issues at the worker process level which happens for massive data and calculation operations. Otherwise, no need because unit testing will need casting.

Regarding awaitable methods: shall I use async/await keywords when I want to query a database (via EF/NHibernate/other ORM)?

Yes, it's better to use async for any DB operation as could as possible to avoid performance issues at the level of worker processes. Note that EF has created many async alternatives for most operations, such as:

.ToListAsync()
.FirstOrDefaultAsync()
.SaveChangesAsync()
.FindAsync()

How many times can I use await keywords to query the database asynchronously in one single action method?

The sky is the limit

In Short: In order to deal with "Leading Zero" numbers (any 0 digit that comes before the first non-zero) in bash - Use bc An arbitrary precision calculator language

Example:

a="000001"
b=$(echo $a | bc)
echo $b

Output: 1

From Bash manual:

"bc is a language that supports arbitrary precision numbers with interactive execution of statements. There are some similarities in the syntax to the C programming lan- guage. A standard math library is available by command line option. If requested, the math library is defined before processing any files. bc starts by processing code from all the files listed on the command line in the order listed. After all files have been processed, bc reads from the standard input. All code is executed as it is read. (If a file contains a command to halt the processor, bc will never read from the standard input.)"

You can do :

try : 
   string_integer = int(string)
except ValueError  :
   print("This string doesn't contain an integer")

In order to fix this issue, the process I have mentioned below.

Please cancel the current process of“react-native run-android” by CTRL + C or CMD + C

Close metro bundler(terminal) window command line which opened automatically.

Run the command again on terminal, “react-native run-android

I think this simple recursive algorithm complementes the accepted answer, in order to generate distinct hue values. I made it for hsv, but can be used for other color spaces too.

It generates hues in cycles, as separate as possible to each other in each cycle.

/**
 * 1st cycle: 0, 120, 240
 * 2nd cycle (+60): 60, 180, 300
 * 3th cycle (+30): 30, 150, 270, 90, 210, 330
 * 4th cycle (+15): 15, 135, 255, 75, 195, 315, 45, 165, 285, 105, 225, 345
 */
public static float recursiveHue(int n) {
    // if 3: alternates red, green, blue variations
    float firstCycle = 3;

    // First cycle
    if (n < firstCycle) {
        return n * 360f / firstCycle;
    }
    // Each cycle has as much values as all previous cycles summed (powers of 2)
    else {
        // floor of log base 2
        int numCycles = (int)Math.floor(Math.log(n / firstCycle) / Math.log(2));
        // divDown stores the larger power of 2 that is still lower than n
        int divDown = (int)(firstCycle * Math.pow(2, numCycles));
        // same hues than previous cycle, but summing an offset (half than previous cycle)
        return recursiveHue(n % divDown) + 180f / divDown;
    }
}

I was unable to find this kind of algorithm here. I hope it helps, it's my first post here.

You have a couple of questions here, so I'll address them separately:

I need to store a number of selected items in one field in a database

My general rule is: don't. This is something which all but requires a second table (or third) with a foreign key. Sure, it may seem easier now, but what if the use case comes along where you need to actually query for those items individually? It also means that you have more options for lazy instantiation and you have a more consistent experience across multiple frameworks/languages. Further, you are less likely to have connection timeout issues (30,000 characters is a lot).

You mentioned that you were thinking about using ENUM. Are these values fixed? Do you know them ahead of time? If so this would be my structure:

Base table (what you have now):

| id primary_key sequence
| -- other columns here.

Items table:

| id primary_key sequence
| descript VARCHAR(30) UNIQUE

Map table:

| base_id  bigint
| items_id bigint

Map table would have foreign keys so base_id maps to Base table, and items_id would map to the items table.

And if you'd like an easy way to retrieve this from a DB, then create a view which does the joins. You can even create insert and update rules so that you're practically only dealing with one table.

What format should I use store the data?

If you have to do something like this, why not just use a character delineated string? It will take less processing power than a CSV, XML, or JSON, and it will be shorter.

What column type should I use store the data?

Personally, I would use TEXT. It does not sound like you'd gain much by making this a BLOB, and TEXT, in my experience, is easier to read if you're using some form of IDE.

Try -Wno-traditional.

But better, add declarations for your static functions:

static void foo (void);

// ... somewhere in code
    foo ();

static void foo ()
{
    // do sth
}

UPDATE:

Starting end August 2012, the API has been updated to allow you to retrieve user's profile pictures in varying sizes. Add the optional width and height fields as URL parameters:

https://graph.facebook.com/USER_ID/picture?width=WIDTH&height=HEIGHT

where WIDTH and HEIGHT are your requested dimension values.

This will return a profile picture with a minimum size of WIDTH x HEIGHT while trying to preserve the aspect ratio. For example,

https://graph.facebook.com/redbull/picture?width=140&height=110

returns

    {
      "data": {
        "url": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash4/c0.19.180.142/s148x148/2624_134501175351_4831452_a.jpg",
        "width": 148,
        "height": 117,
        "is_silhouette": false
      }
   }

END UPDATE

To get a user's profile picture, call

https://graph.facebook.com/USER_ID/picture

where USER_ID can be the user id number or the user name.

To get a user profile picture of a specific size, call

https://graph.facebook.com/USER_ID/picture?type=SIZE

where SIZE should be replaced with one of the words

square
small
normal
large

depending on the size you want.

This call will return a URL to a single image with its size based on your chosen type parameter.

For example:

https://graph.facebook.com/USER_ID/picture?type=small

returns a URL to a small version of the image.

The API only specifies the maximum size for profile images, not the actual size.

Square:

maximum width and height of 50 pixels.

Small

maximum width of 50 pixels and a maximum height of 150 pixels.

Normal

maximum width of 100 pixels and a maximum height of 300 pixels.

Large

maximum width of 200 pixels and a maximum height of 600 pixels.

If you call the default USER_ID/picture you get the square type.

CLARIFICATION

If you call (as per above example)

https://graph.facebook.com/redbull/picture?width=140&height=110

it will return a JSON response if you're using one of the Facebook SDKs request methods. Otherwise it will return the image itself. To always retrieve the JSON, add:

&redirect=false

like so:

https://graph.facebook.com/redbull/picture?width=140&height=110&redirect=false

Swift Solution

Follow these steps:

1. Set the height constraint for the table from the storyboard.

2. Drag the height constraint from the storyboard and create @IBOutlet for it in the view controller file.

   @IBOutlet var tableHeight: NSLayoutConstraint!
   

3. Then you can change the height for the table dynamicaly using this code:

   override func viewWillLayoutSubviews() {
       super.updateViewConstraints()
       self.tableHeight?.constant = self.table.contentSize.height
   }
   

If the last row is cut off, try to call viewWillLayoutSubviews() in willDisplay cell function:

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    self.viewWillLayoutSubviews()
}

Just in my own words, your parent-project helps you provide 2 kind of dependencies:

• implicit dependencies : all the dependencies defined in the <dependencies> section in your parent-project are inherited by all the child-projects
• explicit dependencies : allows you to select, the dependencies to apply in your child-projects. Thus, you use the <dependencyManagement> section, to declare all the dependencies you are going to use in your different child-projects. The most important thing is that, in this section, you define a <version> so that you don't have to declare it again in your child-project.

The <dependencyManagement> in my point of view (correct me if I am wrong) is just useful by helping you centralize the version of your dependencies. It is like a kind of helper feature. As a best practice, your <dependencyManagement> has to be in a parent project, that other projects will inherit. A typical example is the way you create your Spring project by declaring the Spring parent project.

My issue on OSX it was gradle version. Gradle was ignoring my Android.mk. So, in order to override this option, and use my make instead, I have entered this line:

sourceSets.main.jni.srcDirs = []

inside of the android tag in build.gradle.

I have wasted lot of time on this!

If you just want to log the list of elements, you can use the list toString() method which already concatenates all the list elements.

Suppress the newline and print \r.

print 1,
print '\r2'

or write to stdout:

sys.stdout.write('1')
sys.stdout.write('\r2')

Try this

    var myarray = ["item 1", "item 2", "item 3", "item 4"];

    //removes the first element of the array, and returns that element apart from item 1.
    myarray.shift(); 
    console.log(myarray); 

You can clean up a zombie process by killing its parent process with the following command:

kill -HUP $(ps -A -ostat,ppid | awk '{/[zZ]/{ print $2 }')

I got that error because I declared a variable and later wanted to
changed it's value using ngAfterViewInit

export class SomeComponent {

    header: string;

}

to fix that I switched from

ngAfterViewInit() { 

    // change variable value here...
}

to

ngAfterContentInit() {

    // change variable value here...
}

Construct both separate queries and joins, then time each of them -- nothing helps more than real-world numbers.

Then even better -- add "EXPLAIN" to the beginning of each query. This will tell you how many subqueries MySQL is using to answer your request for data, and how many rows scanned for each query.

SHGetKnownFolderPath:

Retrieves the full path of a known folder identified by the folder's KNOWNFOLDERID.

And, FOLDERID_CommonStartup:

Default Path %ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs\StartUp

There are also managed equivalents, but you haven't told us what you're programming in.

Either use a div with square dimensions with the image inside with the .testimg class:

.test {
width: 307px;
height: 307px;
overflow:hidden
}

.testimg {
    margin-left: -76px

}

or a square div with a background of the image.

.test2 {
width: 307px;
height: 307px;
    background: url(http://i.stack.imgur.com/GA6bB.png) 50% 50%
}

Here's some examples: http://jsfiddle.net/QqCLC/1/

UPDATED SO THE IMAGE CENTRES

.test {_x000D_
  width: 307px;_x000D_
  height: 307px;_x000D_
  overflow: hidden_x000D_
}_x000D_
_x000D_
.testimg {_x000D_
  margin-left: -76px_x000D_
}_x000D_

  height: 307px;_x000D_
  background: url(http://i.stack.imgur.com/GA6bB.png) 50% 50%_x000D_
}

<div class="test"><img src="http://i.stack.imgur.com/GA6bB.png" width="460" height="307" class="testimg" /></div>_x000D_

Javascript CLI tools

You can use Javascript CLI tools like

• underscore-cli:
• json:select(): CSS-like selectors for JSON.

Example

Select all name children of a addons:

underscore select ".addons > .name"

The underscore-cli provide others real world examples as well as the json:select() doc.

Don't know why but in my case it doesn't work the way suggested earlier. But it works like this:

Time.now.change(offset: "-3000")

Of course you need to change offset value to yours.

//Write a javascript method to bind click event of each "li" item

    function BindClickEvent()
    {
    var selector = '.nav li';
    //Removes click event of each li
    $(selector ).unbind('click');
    //Add click event
    $(selector ).bind('click', function()
    {
        $(selector).removeClass('active');
        $(this).addClass('active');
    });

    }

//first call this method when first time when page load

    $( document ).ready(function() {
         BindClickEvent();
    });

//Call BindClickEvent method from server side

    protected void Page_Load(object sender, EventArgs e)
    {
        ScriptManager.RegisterStartupScript(Page,GetType(), Guid.NewGuid().ToString(),"BindClickEvent();",true);
    }

You should use this:

<Link to={this.props.myroute} onClick={hello}>Here</Link>

Or (if method hello lays at this class):

<Link to={this.props.myroute} onClick={this.hello}>Here</Link>

Update: For ES6 and latest if you want to bind some param with click method, you can use this:

    const someValue = 'some';  
....  
    <Link to={this.props.myroute} onClick={() => hello(someValue)}>Here</Link>

There is an working java example which can be found here.

 MongoClient mongoClient = new MongoClient();
    DBCollection coll = mongoClient.getDatabase("local").getCollection("oplog.rs");

    DBCursor cur = coll.find().sort(BasicDBObjectBuilder.start("$natural", 1).get())
            .addOption(Bytes.QUERYOPTION_TAILABLE | Bytes.QUERYOPTION_AWAITDATA);

    System.out.println("== open cursor ==");

    Runnable task = () -> {
        System.out.println("\tWaiting for events");
        while (cur.hasNext()) {
            DBObject obj = cur.next();
            System.out.println( obj );

        }
    };
    new Thread(task).start();

The key is QUERY OPTIONS given here.

Also you can change find query, if you don't need to load all the data every time.

BasicDBObject query= new BasicDBObject();
query.put("ts", new BasicDBObject("$gt", new BsonTimestamp(1471952088, 1))); //timestamp is within some range
query.put("op", "i"); //Only insert operation

DBCursor cur = coll.find(query).sort(BasicDBObjectBuilder.start("$natural", 1).get())
.addOption(Bytes.QUERYOPTION_TAILABLE | Bytes.QUERYOPTION_AWAITDATA);

The answer is -flto. You have to pass it to both your compilation and link steps, otherwise it doesn't do anything.

It actually works very well - reduced the size of a microcontroller program I wrote to less than 50% of its previous size!

Unfortunately it did seem a bit buggy - I had instances of things not being built correctly. It may have been due to the build system I'm using (QBS; it's very new), but in any case I'd recommend you only enable it for your final build if possible, and test that build thoroughly.

Use the push() function to append to an array:

// initialize array
var arr = [
    "Hi",
    "Hello",
    "Bonjour"
];

// append new value to the array
arr.push("Hola");

Now array is

var arr = [
    "Hi",
    "Hello",
    "Bonjour"
    "Hola"
];

// append multiple values to the array
arr.push("Salut", "Hey");

Now array is

var arr = [
    "Hi",
    "Hello",
    "Bonjour"
    "Hola"
    "Salut"
    "Hey"
];

// display all values
for (var i = 0; i < arr.length; i++) {
    console.log(arr[i]);
}

Will print:

Hi
Hello
Bonjour
Hola 
Salut
Hey

Update

If you want to add the items of one array to another array, you can use Array.concat:

var arr = [
    "apple",
    "banana",
    "cherry"
];

arr = arr.concat([
    "dragonfruit",
    "elderberry",
    "fig"
]);

console.log(arr);

Will print

["apple", "banana", "cherry", "dragonfruit", "elderberry", "fig"]

Auto-generate one form from another.

Source:

enum {
  VALUE1, /* value 1 */
  VALUE2, /* value 2 */
};

Generated:

const char* enum2str[] = {
  "value 1", /* VALUE1 */
  "value 2", /* VALUE2 */
};

If enum values are large then a generated form could use unordered_map<> or templates as suggested by Constantin.

Source:

enum State{
  state0 = 0, /* state 0 */
  state1 = 1, /* state 1 */
  state2 = 2, /* state 2 */
  state3 = 4, /* state 3 */

  state16 = 0x10000, /* state 16 */
};

Generated:

template <State n> struct enum2str { static const char * const value; };
template <State n> const char * const enum2str<n>::value = "error";

template <> struct enum2str<state0> { static const char * const value; };
const char * const enum2str<state0>::value = "state 0";

Example:

#include <iostream>

int main()
{
  std::cout << enum2str<state16>::value << std::endl;
  return 0;
}

Following solution is better than bootbox.js, because

• It can do everything bootbox.js can do;
• The use syntax is simpler
• It allows you to elegantly control the color of your message using "error", "warning" or "info"
• Bootbox is 986 lines long, mine only 110 lines long

There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)

You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.

UNAME := $(shell uname -m)

all:
    $(info Checking if custom header is needed)
    ifeq ($(UNAME), x86_64)
    ... do some things to build unistd_32.h
    endif

    @make -C $(KDIR) M=$(PWD) modules

So you want unistd_32.h built (maybe) before you invoke the second make, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:

ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif

all:
    @make -C $(KDIR) M=$(PWD) modules

unistd_32.h:
    ... do some things to build unistd_32.h

Now for building unistd_32.h:

F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
    $(info Copying custom header)
    $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else    
    F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
    ifeq ($(F2_EXISTS), 1)
        $(info Copying custom header)
        $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
    else
        $(error asm/unistd_32.h and asm-386/unistd.h does not exist)
    endif
endif

You are trying to build unistd.h from unistd_32.h; the only trick is that unistd_32.h could be in either of two places. The simplest way to clean this up is to use a vpath directive:

vpath unistd.h /usr/include/asm /usr/include/asm-i386

unistd_32.h: unistd.h
    sed -e 's/__NR_/__NR32_/g' $< > $@

I am almost sure you are not actually getting it installed correctly. Since you are trying to install it globally, you will need to run it with sudo:

sudo npm install -g bower

"Once upon a time there were three little pigs".Split(" ") | ForEach {
    "$_ is a token"
 }

The key is $_, which stands for the current variable in the pipeline.

About the code you found online:

% is an alias for ForEach-Object. Anything enclosed inside the brackets is run once for each object it receives. In this case, it's only running once, because you're sending it a single string.

$_.Split(" ") is taking the current variable and splitting it on spaces. The current variable will be whatever is currently being looped over by ForEach.

I had the same problem of @rutherford, today the new phpMyAdmin's 3.4.11.1 GUI is different, so I figure out it's better if someone improves the answers with updated info.

This is the answer, doesn't matter if you're using MAMP, XAMPP, LAMP, etc.

You can try to do something like:

textView.getBackground().setAlpha(51);

Here you can set the opacity between 0 (fully transparent) to 255 (completely opaque). The 51 is exactly the 20% you want.

USE Chrome's Search Bar

4-paste in Notepad++
5-replace 'space' with ','

Orika's is simple faster bean mapping framework because it does through byte code generation. It does nested mappings and mappings with different names. For more details, please check here Sample mapping may look complex, but for complex scenarios it would be simple.

MapperFactory factory = new DefaultMapperFactory.Builder().build();
mapperFactory.registerClassMap(mapperFactory.classMap(Book.class,BookDto.class).byDefault().toClassMap());
MapperFacade mapper = factory.getMapperFacade();
BookDto bookDto = mapperFacade.map(book, BookDto.class);

Any Java collection can be made to be Thread-safe like so:

List newList = Collections.synchronizedList(oldList);

Or to create a brand new thread-safe list:

List newList = Collections.synchronizedList(new ArrayList());

I have just discovered a way to append text and its working fine at least.

 var text = 'Put any text here';
 $('#text').append(text);

You can change text according to your need.

Hope this helps.

This will do. Pretty trustworthy. : )

    ""+number;

Just to clarify, this works and acceptable to use unless you are looking for micro optimization.

$get_url = "http://google.com/?var=234&key=234";
$my_url = "http://localhost/test.php?id=" . urlencode($get_url);

$my_url outputs:

http://localhost/test.php?id=http%3A%2F%2Fgoogle.com%2F%3Fvar%3D234%26key%3D234

So now you can get this value using $_GET['id'] or $_REQUEST['id'] (decoded).

echo urldecode($_GET["id"]);

Output

http://google.com/?var=234&key=234

To get every GET parameter:

foreach ($_GET as $key=>$value) {
  echo "$key = " . urldecode($value) . "<br />\n";
  }

$key is GET key and $value is GET value for $key.

Or you can use alternative solution to get array of GET params

$get_parameters = array();
if (isset($_SERVER['QUERY_STRING'])) {
  $pairs = explode('&', $_SERVER['QUERY_STRING']);
  foreach($pairs as $pair) {
    $part = explode('=', $pair);
    $get_parameters[$part[0]] = sizeof($part)>1 ? urldecode($part[1]) : "";
    }
  }

$get_parameters is same as url decoded $_GET.

You should indeed start with the Mandelbrot set, and understand what it really is.

The idea behind it is relatively simple. You start with a function of complex variable

f(z) = z² + C

where z is a complex variable and C is a complex constant. Now you iterate it starting from z = 0, i.e. you compute z₁ = f(0), z₂ = f(z₁), z₃ = f(z₂) and so on. The set of those constants C for which the sequence z₁, z₂, z₃, ... is bounded, i.e. it does not go to infinity, is the Mandelbrot set (the black set in the figure on the Wikipedia page).

In practice, to draw the Mandelbrot set you should:

• Choose a rectangle in the complex plane (say, from point -2-2i to point 2+2i).
• Cover the rectangle with a suitable rectangular grid of points (say, 400x400 points), which will be mapped to pixels on your monitor.
• For each point/pixel, let C be that point, compute, say, 20 terms of the corresponding iterated sequence z₁, z₂, z₃, ... and check whether it "goes to infinity". In practice you can check, while iterating, if the absolute value of one of the 20 terms is greater than 2 (if one of the terms does, the subsequent terms are guaranteed to be unbounded). If some z_k does, the sequence "goes to infinity"; otherwise, you can consider it as bounded.
• If the sequence corresponding to a certain point C is bounded, draw the corresponding pixel on the picture in black (for it belongs to the Mandelbrot set). Otherwise, draw it in another color. If you want to have fun and produce pretty plots, draw it in different colors depending on the magnitude of abs(20th term).

The astounding fact about fractals is how we can obtain a tremendously complex set (in particular, the frontier of the Mandelbrot set) from easy and apparently innocuous requirements.

Enjoy!

This is still a matplotlib object. Try this:

# <your code here>
locs, labels = plt.xticks()
plt.setp(labels, rotation=45)

I did this today, the difference being I wanted to uncheck the oldest checkbox instead of stopping the user from checking a new one:

    let maxCheckedArray = [];
    let assessmentOptions = jQuery('.checkbox-fields').find('input[type="checkbox"]');
    assessmentOptions.on('change', function() {
        let checked = jQuery(this).prop('checked');
        if(checked) {
            maxCheckedArray.push(jQuery(this));
        }
        if(maxCheckedArray.length >= 3) {
            let old_item = maxCheckedArray.shift();
            old_item.prop('checked', false);
        }
    });

You can do something like this, where you set a negative margin on the h1 (or whatever header you are using)

div{
    height:100px;
    width:100px;
    border:2px solid black;
}

h1{
    width:30px;
    margin-top:-10px;
    margin-left:5px;
    background:white;
}

Note: you need to set a background as well as a width on the h1

Example: http://jsfiddle.net/ZgEMM/

EDIT

To make it work with hiding the div, you could use some jQuery like this

$('a').click(function(){
    var a = $('h1').detach();
    $('div').hide();
    $(a).prependTo('body');    
});

(You will need to modify...)

Example #2: http://jsfiddle.net/ZgEMM/4/

use cv::mat::setto

img.setTo(cv::Scalar(redVal,greenVal,blueVal))

    <div>
    <p style="text-align:center; margin-top:0px; margin-bottom:0px; padding:0px;">
    <img src="image.jpg" alt="image"/>
    </p>    
    </div>

To delete a key regardless of whether it is in the dictionary, use the two-argument form of dict.pop():

my_dict.pop('key', None)

This will return my_dict[key] if key exists in the dictionary, and None otherwise. If the second parameter is not specified (ie. my_dict.pop('key')) and key does not exist, a KeyError is raised.

To delete a key that is guaranteed to exist, you can also use

del my_dict['key']

This will raise a KeyError if the key is not in the dictionary.

Use the following code:

import numpy as np

myArray=np.array([1,2,4])  #func used to convert [1,2,3] list into an array
print(myArray)

I've heard about having to use BackgroundImage because in future you are supposed to not be able to nest the Image tag. But I could not get BackgroudImage to properly display my background. What I did was nest my Image inside a View tag and style both the outer View as well as the image. Keys were setting width to null, and setting resizeMode to 'stretch'. Below is my code:

import React, {Component} from 'react';_x000D_
import { View, Text, StyleSheet, Image} from 'react-native';_x000D_
_x000D_
export default class BasicImage extends Component {_x000D_
 constructor(props) {_x000D_
   super(props);_x000D_
_x000D_
   this.state = {};_x000D_
 }_x000D_
_x000D_
 render() {_x000D_
  return (_x000D_
   <View style={styles.container}>_x000D_
       <Image _x000D_
         source={this.props.source}_x000D_
         style={styles.backgroundImage}_x000D_
       />_x000D_
      </View>_x000D_
  )_x000D_
 }_x000D_
}_x000D_
_x000D_
const styles = StyleSheet.create({   _x000D_
  container: {_x000D_
   flex: 1,_x000D_
   width: null,_x000D_
   height: null,_x000D_
   marginBottom: 50_x000D_
  },_x000D_
    text: {_x000D_
      marginLeft: 5,_x000D_
      marginTop: 22,_x000D_
      fontFamily: 'fontawesome',_x000D_
        color: 'black',_x000D_
        fontSize: 25,_x000D_
        backgroundColor: 'rgba(0,0,0,0)',_x000D_
    },_x000D_
  backgroundImage: {_x000D_
   flex: 1,_x000D_
   width: null,_x000D_
   height: null,_x000D_
   resizeMode: 'stretch',_x000D_
  }_x000D_
});

Try this example

 String[] formats = new String[] {
   "yyyy-MM-dd",
   "yyyy-MM-dd HH:mm",
   "yyyy-MM-dd HH:mmZ",
   "yyyy-MM-dd HH:mm:ss.SSSZ",
   "yyyy-MM-dd'T'HH:mm:ss.SSSZ",
 };
 for (String format : formats) {
   SimpleDateFormat sdf = new SimpleDateFormat(format, Locale.US);
   System.err.format("%30s %s\n", format, sdf.format(new Date(0)));
   sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
   System.err.format("%30s %s\n", format, sdf.format(new Date(0)));
 }

XML Schemas describe hierarchial data models and may not map well to a relational data model. Mapping XSD's to database tables is very similar mapping objects to database tables, in fact you could use a framework like Castor that does both, it allows you to take a XML schema and generate classes, database tables, and data access code. I suppose there are now many tools that do the same thing, but there will be a learning curve and the default mappings will most like not be what you want, so you have to spend time customizing whatever tool you use.

XSLT might be the fastest way to generate exactly the code that you want. If it is a small schema hardcoding it might be faster than evaluating and learing a bunch of new technologies.

Omit the "~\":

var path = @"FolderIcon\Folder.ico";

~\ doesn't mean anything in terms of the file system. The only place I've seen that correctly used is in a web app, where ASP.NET replaces the tilde with the absolute path to the root of the application.

You can typically assume the paths are relative to the folder where the EXE is located. Also, make sure that the image is specified as "content" and "copy if newer"/"copy always" in the properties tab in Visual Studio.

You can call the method like pump.getPumps(). By adding @classmethod decorator on the method. A class method receives the class as the implicit first argument, just like an instance method receives the instance.

class Pump:

def __init__(self):
    print ("init") # never prints

@classmethod
def getPumps(cls):
            # Open database connection
            # some stuff here that never gets executed because of error

So, simply call Pump.getPumps() .

In java, it is termed as static method.

first hit for "java file exists" on google:

import java.io.*;

public class FileTest {
    public static void main(String args[]) {
        File f = new File(args[0]);
        System.out.println(f + (f.exists()? " is found " : " is missing "));
    }
}

Before answering, I would like to give you some data from Wiki

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding.

When a modern computer reads from or writes to a memory address, it will do this in word sized chunks (e.g. 4 byte chunks on a 32-bit system). Data alignment means putting the data at a memory offset equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory.

To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

gcc provides functionality to disable structure padding. i.e to avoid these meaningless bytes in some cases. Consider the following structure:

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}sSampleStruct;

sizeof(sSampleStruct) will be 12 rather than 8. Because of structure padding. By default, In X86, structures will be padded to 4-byte alignment:

typedef struct
{
     char Data1;
     //3-Bytes Added here.
     int Data2;
     unsigned short Data3;
     char Data4;
     //1-byte Added here.

}sSampleStruct;

We can use __attribute__((packed, aligned(X))) to insist particular(X) sized padding. X should be powers of two. Refer here

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}__attribute__((packed, aligned(1))) sSampleStruct;  

so the above specified gcc attribute does not allow the structure padding. so the size will be 8 bytes.

If you wish to do the same for all the structures, simply we can push the alignment value to stack using #pragma

#pragma pack(push, 1)

//Structure 1
......

//Structure 2
......

#pragma pack(pop)

It is a C extension from the GCC compiler , see http://gcc.gnu.org/onlinedocs/gcc/Typeof.html

For ASP.NET Core You can use asp-route-* attribute:

<form asp-action="Login" asp-route-previous="@Model.ReturnUrl">

Other in details example: Imagine that you have a Vehicle Controller with actions

Index

Details

Edit

and you can edit any vehicle from Index or from Details, so if you clicked edit from index you must return to index after edit and if you clicked edit from details you must return to details after edit.

//In your viewmodel add the ReturnUrl Property
public class VehicleViewModel
{
     ..............
     ..............
     public string ReturnUrl {get;set;}
}



Details.cshtml
<a asp-action="Edit" asp-route-previous="Details" asp-route-id="@Model.CarId">Edit</a>

Index.cshtml
<a asp-action="Edit" asp-route-previous="Index" asp-route-id="@item.CarId">Edit</a>

Edit.cshtml
<form asp-action="Edit" asp-route-previous="@Model.ReturnUrl" class="form-horizontal">
        <div class="box-footer">
            <a asp-action="@Model.ReturnUrl" class="btn btn-default">Back to List</a>
            <button type="submit" value="Save" class="btn btn-warning pull-right">Save</button>
        </div>
    </form>

In your controller:

// GET: Vehicle/Edit/5
    public ActionResult Edit(int id,string previous)
    {
            var model = this.UnitOfWork.CarsRepository.GetAllByCarId(id).FirstOrDefault();
            var viewModel = this.Mapper.Map<VehicleViewModel>(model);//if you using automapper
    //or by this code if you are not use automapper
    var viewModel = new VehicleViewModel();

    if (!string.IsNullOrWhiteSpace(previous)
                viewModel.ReturnUrl = previous;
            else
                viewModel.ReturnUrl = "Index";
            return View(viewModel);
        }



[HttpPost]
    public IActionResult Edit(VehicleViewModel model, string previous)
    {
            if (!string.IsNullOrWhiteSpace(previous))
                model.ReturnUrl = previous;
            else
                model.ReturnUrl = "Index";
            ............. 
            .............
            return RedirectToAction(model.ReturnUrl);
    }

When I tried to set theme attribute to TextInputLayout, the theme was also getting applied to its child view edittext, which I didn't wanted.

So the solution which worked for me was to add a custom style to the "app:hintTextAppearance" property of the TextInputLayout.

In styles.xml add the following style:

<style name="TextInputLayoutTextAppearance" parent="TextAppearance.AppCompat">
    <item name="android:textColor">@color/text_color</item>
    <item name="android:textSize">@dimen/text_size_12</item>
</style>

And apply this style to the "app:hintTextAppearance" property of the TextInputLayout as below:

<com.google.android.material.textfield.TextInputLayout
        android:id="@+id/mobile_num_til"
        android:layout_width="0dp"
        android:layout_height="@dimen/dim_56"
        app:layout_constraintStart_toStartOf="@id/title_tv"
        app:layout_constraintEnd_toEndOf="@id/title_tv"
        app:layout_constraintTop_toBottomOf="@id/sub_title_tv"
        android:layout_marginTop="@dimen/dim_30"
        android:padding="@dimen/dim_8"
        app:hintTextAppearance="@style/TextInputLayoutTextAppearance"
        android:background="@drawable/rect_round_corner_grey_outline">

        <com.google.android.material.textfield.TextInputEditText
            android:id="@+id/mobile_num_et"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:hint="@string/mobile_number"
            android:gravity="center_vertical"
            android:background="@android:color/transparent"/>

    </com.google.android.material.textfield.TextInputLayout>

I just tried the same in EF6 (code first entity rename). I simply renamed the class and added a migration using the package manager console and voila, a migration using RenameTable(...) was automatically generated for me. I have to admit that I made sure the only change to the entity was renaming it so no new columns or renamed columns so I cannot be certain if this is an EF6 thing or just that EF was (always) able to detect such simple migrations.

The javax.servlet dependency is missing in your pom.xml. Add the following to the dependencies-Node:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>

I'm surprised nobody suggest this simple approach to creating a list of empty lists. This is an old thread, but just adding this for completeness. This will create a list of 10 empty lists

x = [[] for i in range(10)]

For those that wish to use javascript but do not want to use the Facebook javascript library:

<a id="shareFB" href="https://www.facebook.com/sharer/sharer.php?u=URLENCODED_URL&t=TITLE"
   onclick="javascript:window.open(this.href, '', 'menubar=no,toolbar=no,resizable=yes,scrollbars=yes,height=300,width=600');return false;"   target="_blank" title="Share on Facebook">Share on Facebook</a>
<script type="text/javascript">document.getElementById("shareFB").setAttribute("href", "https://www.facebook.com/sharer/sharer.php?u=" + document.URL);</script>

Works even if javascript is disabled, but gives you a popup window with share preview if javascript is enabled.

Saves one needles click while not using any Facebook js spyware :)

I created a jQuery function in order to make this task a bit easier. Probably now there is a better solution... either way, here's my 2cents. :)

Just add this to your JS file:

$.fn.dialogButtons = function(name, state){
var buttons = $(this).next('div').find('button');
if(!name)return buttons;
return buttons.each(function(){
    var text = $(this).text();
    if(text==name && state=='disabled') {$(this).attr('disabled',true).addClass('ui-state-disabled');return this;}
    if(text==name && state=='enabled') {$(this).attr('disabled',false).removeClass('ui-state-disabled');return this;}
    if(text==name){return this;}
    if(name=='disabled'){$(this).attr('disabled',true).addClass('ui-state-disabled');return buttons;}
    if(name=='enabled'){$(this).attr('disabled',false).removeClass('ui-state-disabled');return buttons;}
});};

Disable button 'Ok' on dialog with class 'dialog':

$('.dialog').dialogButtons('Ok', 'disabled');

Enable all buttons:

$('.dialog').dialogButtons('enabled');

Enable 'Close' button and change color:

$('.dialog').dialogButtons('Close', 'enabled').css('color','red');

Text on all buttons red:

$('.dialog').dialogButtons().css('color','red');

Hope this helps :)

The statement about CMake being a "build generator" is a common misconception.

It's not technically wrong; it just describes HOW it works, but not WHAT it does.

In the context of the question, they do the same thing: take a bunch of C/C++ files and turn them into a binary.

So, what is the real difference?

• CMake is much more high-level. It's tailored to compile C++, for which you write much less build code, but can be also used for general purpose build. make has some built-in C/C++ rules as well, but they are useless at best.

• CMake does a two-step build: it generates a low-level build script in ninja or make or many other generators, and then you run it. All the shell script pieces that are normally piled into Makefile are only executed at the generation stage. Thus, CMake build can be orders of magnitude faster.

• The grammar of CMake is much easier to support for external tools than make's.

• Once make builds an artifact, it forgets how it was built. What sources it was built from, what compiler flags? CMake tracks it, make leaves it up to you. If one of library sources was removed since the previous version of Makefile, make won't rebuild it.

• Modern CMake (starting with version 3.something) works in terms of dependencies between "targets". A target is still a single output file, but it can have transitive ("public"/"interface" in CMake terms) dependencies. These transitive dependencies can be exposed to or hidden from the dependent packages. CMake will manage directories for you. With make, you're stuck on a file-by-file and manage-directories-by-hand level.

You could code up something in make using intermediate files to cover the last two gaps, but you're on your own. make does contain a Turing complete language (even two, sometimes three counting Guile); the first two are horrible and the Guile is practically never used.

To be honest, this is what CMake and make have in common -- their languages are pretty horrible. Here's what comes to mind:

• They have no user-defined types;
• CMake has three data types: string, list, and a target with properties. make has one: string;
• you normally pass arguments to functions by setting global variables.
  • This is partially dealt with in modern CMake - you can set a target's properties: set_property(TARGET helloworld APPEND PROPERTY INCLUDE_DIRECTORIES "${CMAKE_CURRENT_SOURCE_DIR}");
• referring to an undefined variable is silently ignored by default;

=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

Arcadia, just try the code below. There are several ways to get the result you're looking for, this is one of the easier ways.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/relative_layout"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:gravity="center">

    <Button
        android:id="@+id/the_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Centered Button"/>
</RelativeLayout>

Setting the gravity of the RelativeLayout itself will affect all of the objects placed inside of it. In this case, it's just the button. You can use any of the gravity settings here, of course (e.g. center_horizontal, top, right, and so on).

You could also use this code below:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/relative_layout"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent">

    <Button
        android:id="@+id/the_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Centered Button"
        android:layout_centerInParent="true"/>
</RelativeLayout>

For adding a ToolBar that supports Material Design, the official documentation directions are probably the best to follow.

1. Add the v7 appcompat support library.

2. Make your activity extend AppCompatActivity.

   public class MyActivity extends AppCompatActivity {
     // ...
   }
   

3. Declare NoActionBar in the Manifest.

   <application
       android:theme="@style/Theme.AppCompat.Light.NoActionBar"
       />
   

4. Add a toolbar to your activity's xml layout.

   <android.support.v7.widget.Toolbar
      android:id="@+id/my_toolbar"
      android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
      ...
      />
   

5. Call setSupportActionBar in the activity's onCreate.

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_my);
       Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
       setSupportActionBar(myToolbar);
   }
   

Note: You will have to import the following in the activity.

import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;

It calculates e^x for each x in your list where e is Euler's number (approximately 2.718). In other words, np.exp(range(5)) is similar to [math.e**x for x in range(5)].

Nitin is correct - the issue is actually in the MDB2 code.

According to Replacement for PEAR: MDB2 on PHP 5.3 you can update to the SVN version of MDB2 for a version which is PHP5.3 compatible.

As that answer was given in March 2010, and http://pear.php.net/package/MDB2/ shows a release some months later, I expect the current version of MDB2 will solve the issue also.

As Julius says this happens when an update Occurs on an Object that has its children being deleted. (Probably because there was a need for an update for the whole Father Object and sometimes we prefer to delete the children and re -insert them on the Father (new , old doesnt matter )along with any other updates the father could have on any of its other plain fields) So ...in order for this to work delete the children (within a Transaction) by calling childrenList.clear() (Dont loop through the children and delete each one with some childDAO.delete(childrenList.get(i).delete())) and setting @OneToMany(cascade = CascadeType.XXX ,orphanRemoval=true) on the Side of the Father Object. Then update the father (fatherDAO.update(father)). (Repeat for every father object) The result is that children have their link to their father stripped off and then they are being removed as orphans by the framework.

>>> li = ['aaa', 'bbb']
>>> li.insert(0, 'wow!')
>>> li
['wow!', 'aaa', 'bbb']

Instead of creating runner functions or using set -e, use a trap:

trap 'echo "error"; do_cleanup failed; exit' ERR
trap 'echo "received signal to stop"; do_cleanup interrupted; exit' SIGQUIT SIGTERM SIGINT

do_cleanup () { rm tempfile; echo "$1 $(date)" >> script_log; }

command1
command2
command3

The trap even has access to the line number and the command line of the command that triggered it. The variables are $BASH_LINENO and $BASH_COMMAND.

If all of these rows are related and you need to alter the tabular data ... why not just wrap the entire table in a form, and change GET to POST (unless you know that you're not going to be sending more than the max amount of data a GET request can send).

I cannot wrap the entire table in a form, because some input fields of each row are input type="file" and files may be large. When the user submits the form, I want to POST only fields of current row, not all fields of the all rows which may have unneeded huge files, causing form to submit very slowly.

So, I tried incorrect nesting: tr/form and form/tr. However, it works only when one does not try to add new inputs dynamically into the form. Dynamically added inputs will not belong to incorrectly nested form, thus won't get submitted. (valid form/table dynamically inputs are submitted just fine).

Nesting div[display:table]/form/div[display:table-row]/div[display:table-cell] produced non-uniform widths of grid columns. I managed to get uniform layout when I replaced div[display:table-row] to form[display:table-row] :

div.grid {
    display: table;
}

div.grid > form {
    display: table-row;


div.grid > form > div {
    display: table-cell;
}
div.grid > form > div.head {
    text-align: center;
    font-weight: 800;
}

For the layout to be displayed correctly in IE8:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
...
<meta http-equiv="X-UA-Compatible" content="IE=8, IE=9, IE=10" />

Sample of output:

<div class="grid" id="htmlrow_grid_item">
<form>
    <div class="head">Title</div>
    <div class="head">Price</div>
    <div class="head">Description</div>
    <div class="head">Images</div>
    <div class="head">Stock left</div>
    <div class="head">Action</div>
</form>
<form action="/index.php" enctype="multipart/form-data" method="post">
    <div title="Title"><input required="required" class="input_varchar" name="add_title" type="text" value="" /></div>

It would be much harder to make this code work in IE6/7, however.

I have resolve the problem as below 1. Get the tag from your branch 2. Write below command

Example: git branch <Hotfix branch> <TAG>
    git branch hotfix_4.4.3 v4.4.3
    git checkout hotfix_4.4.3

or you can do with other command

git checkout -b <Hotfix branch> <TAG>
-b stands for creating new branch to local 

once you ready with your hotfix branch, It's time to move that branch to github, you can do so by writing below command

git push --set-upstream origin hotfix_4.4.3

You could prepare the query for inserting one row using the mysqli_stmt class, and then iterate over the array of data. Something like:

$stmt =  $db->stmt_init();
$stmt->prepare("INSERT INTO mytbl (fld1, fld2, fld3, fld4) VALUES(?, ?, ?, ?)");
foreach($myarray as $row)
{
    $stmt->bind_param('idsb', $row['fld1'], $row['fld2'], $row['fld3'], $row['fld4']);
    $stmt->execute();
}
$stmt->close();

Where 'idsb' are the types of the data you're binding (int, double, string, blob).

My problem occurs when I try to open https. I don't use SSL.

It's Tomcat bug.

Today 12/02/2017 newest official version from Debian repositories is Tomcat 8.0.14

Solution is to download from official site and install newest package of Tomcat 8, 8.5, 9 or upgrade to newest version(8.5.x) from jessie-backports

Debian 8

Add to /etc/apt/sources.list

deb http://ftp.debian.org/debian jessie-backports main

Then update and install Tomcat from jessie-backports

sudo apt-get update && sudo apt-get -t jessie-backports install tomcat8

With C#6.0 you also have a new way of formatting date when using string interpolation e.g.

$"{DateTime.Now:yyyy-MM-dd HH:mm:ss}"

Can't say its any better, but it is slightly cleaner if including the formatted DateTime in a longer string.

More about string interpolation.

I believe MonsCamus meant:

parsememo = Regex.Replace(parsememo, @"[^\u0020-\u007E]", string.Empty);

After long research, I got this thing working. See the following code:

Test.java

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;

public class Test extends Activity {

    HTML5WebView mWebView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mWebView = new HTML5WebView(this);

        if (savedInstanceState != null) {
            mWebView.restoreState(savedInstanceState);
        } else {    
            mWebView.loadUrl("http://192.168.1.18/xxxxxxxxxxxxxxxx/");
        }

        setContentView(mWebView.getLayout());
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        mWebView.saveState(outState);
    }

    @Override
    public void onStop() {
        super.onStop();
        mWebView.stopLoading();
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {

        if (keyCode == KeyEvent.KEYCODE_BACK) {
            if (mWebView.inCustomView()) {
                mWebView.hideCustomView();
            //  mWebView.goBack();
                //mWebView.goBack();
                return true;
            }

        }
        return super.onKeyDown(keyCode, event);
    }
}

The easiest way I have tested just add a <br> as in the following:

<div class="col-sm-6">
    <br><h3><p class="text-center">Some Text</p></h3>
</div>

The only problem is that a extra line break (generated by that <br>) is generated when the screen gets smaller and it stacks. But it is quick and simple.

objds.Table1.Select(r => r.ProcessName).AsEnumerable().Distinct();

Say st is your unformatted string, then run

st_nodigits=''.join(i for i in st if i.isalpha())

as mentioned above. But my guess that you need something very simple so say s is your string and st_res is a string without digits, then here is your code

l = ['0','1','2','3','4','5','6','7','8','9']
st_res=""
for ch in s:
 if ch not in l:
  st_res+=ch

One liner is the best :

db.mycollection.find({ 'fieldname' : { $exists: true, $ne: null } });

Here,

mycollection : place your desired collection name

fieldname : place your desired field name

Explaination :

$exists : When is true, $exists matches the documents that contain the field, including documents where the field value is null. If is false, the query returns only the documents that do not contain the field.

$ne selects the documents where the value of the field is not equal to the specified value. This includes documents that do not contain the field.

So in your provided case following query going to return all the documents with imageurl field exists and having not null value:

db.mycollection.find({ 'imageurl' : { $exists: true, $ne: null } });

you need a return statement in your first function.

function first(){
    var nameContent = document.getElementById('full_name').value;
    return nameContent;
}

and then in your second function can be:

function second(){
    alert(first());
}

This should work.

<!DOCTYPE html>
<html>
    <head>
        <title>Hello World</title>
        <style>
            html, body {
                width: 100%;
                height: 100%;
                margin: 0;
                padding: 0;
                background-color: green;
            }
            #container {
                width: inherit;
                height: inherit;
                margin: 0;
                padding: 0;
                background-color: pink;
            }
            h1 {
                margin: 0;
                padding: 0;
            }
        </style>
    </head>
    <body>
        <div id="container">
            <h1>Hello World</h1>
        </div>
    </body>
</html>

The background colors are there so you can see how this works. Copy this code to a file and open it in your browser. Try playing around with the CSS a bit and see what happens.

The width: inherit; height: inherit; pulls the width and height from the parent element. This should be the default and is not truly necessary.

Try removing the h1 { ... } CSS block and see what happens. You might notice the layout reacts in an odd way. This is because the h1 element is influencing the layout of its container. You could prevent this by declaring overflow: hidden; on the container or the body.

I'd also suggest you do some reading on the CSS Box Model.

If you are trying to find a View from your Fragment then try doing it like this:

int w = ((EditText)getActivity().findViewById(R.id.editText1)).getLayoutParams().width;

This is for longs, but you can modify it easily to work with ints.

private static long[] ConvertStringArrayToLongArray(string str)
{
    return str.Split(",".ToCharArray()).Select(x => long.Parse(x.ToString())).ToArray();
}

$url = 'http://www.example.com'; $xml = simpleXML_load_file($url,"SimpleXMLElement",LIBXML_NOCDATA);

$url can be php file, as long as the file generate xml format data as output.

I am working on DOM Keyboard Event Level 3 polyfill . In latest browsers or with this polyfill you can do something like this:

element.addEventListener("keydown", function(e){ console.log(e.key, e.char, e.keyCode) })

var e = new KeyboardEvent("keydown", {bubbles : true, cancelable : true, key : "Q", char : "Q", shiftKey : true});
element.dispatchEvent(e);

//If you need legacy property "keyCode"
// Note: In some browsers you can't overwrite "keyCode" property. (At least in Safari)
delete e.keyCode;
Object.defineProperty(e, "keyCode", {"value" : 666})

UPDATE:

Now my polyfill supports legacy properties "keyCode", "charCode" and "which"

var e = new KeyboardEvent("keydown", {
    bubbles : true,
    cancelable : true,
    char : "Q",
    key : "q",
    shiftKey : true,
    keyCode : 81
});

Examples here

Additionally here is cross-browser initKeyboardEvent separately from my polyfill: (gist)

Simply declare it as below if you want to us the STL queue container.

std::queue<myclass*> my_queue;

Specify the maxrecursion option at the end of the query:

...
from EmployeeTree
option (maxrecursion 0)

That allows you to specify how often the CTE can recurse before generating an error. Maxrecursion 0 allows infinite recursion.

Solution: Remove height: 100% in .item-inner and add display: flex in .item

Demo: https://codepen.io/tronghiep92/pen/NvzVoo

The key here is the name attribute of the f object representing the opened file. You get it like that:

>>> f = open('/Users/Desktop/febROSTER2012.xls')
>>> f.name
'/Users/Desktop/febROSTER2012.xls'

Does it help?

Try this Javascript (jquery) code. Its an ajax request to an external URL. Use the callback function to fire any code:

<script type="text/javascript">
$(function() {
  $('form').submit(function(){
    $.post('http://example.com/upload', function() {
      window.location = 'http://google.com';
    });
    return false;
  });
});
</script>

I would generally recommend using element.attachEvent (IE) or element.addEventListener (other browsers) over setting the onclick event directly as the latter will replace any existing event handlers for that element.

attachEvent / addEventListening allow multiple event handlers to be created.

It's a bit surprising seeing multiple answers suggesting to use python for this task, as there's no need to write a multi-line program for this.

Standard Unix tools like sed, awk or perl can achieve this easily straight from the command-line.

e.g anywhere you have perl (Windows, Mac, Linux) the following should achieve what the OP asked:

perl -i -pe 's/[ \t]+$//;' files...

Explanation of the arguments to perl:

-i   # run the edit "in place" (modify the original file)
-p   # implies a loop with a final print over every input line
-e   # next arg is the perl expression to apply (to every line)

s/[ \t]$// is a substitution regex s/FROM/TO/: replace every trailing (end of line) non-empty space (spaces or tabs) with nothing.

Advantages:

• One liner, no programming needed
• Works on multiple (any number) of files
• Works correctly on standard-input (no file arguments given)

Edit:

Newer versions of perl support \h (any horizontal-space character), so the solution becomes even shorter:

perl -i -pe 's/\h+$//;' files...

More generally, if you want to modify any number of files directly from the command line, replacing every appearance of FOO with BAR, you may always use this generic template:

perl -i -pe 's/FOO/BAR/' files...

I was trying to import numpy in python 3.2.1 on windows 7.

Followed suggestions in above answer for numpy-1.6.1.zip as below after unzipping it

cd numpy-1.6
python setup.py install

but got an error with a statement as below

unable to find vcvarsall.bat

For this error I found a related question here which suggested installing mingW. MingW was taking some time to install.

In the meanwhile tried to install numpy 1.6 again using the direct windows installer available at this link the file name is "numpy-1.6.1-win32-superpack-python3.2.exe"

Installation went smoothly and now I am able to import numpy without using mingW.

Long story short try using windows installer for numpy, if one is available.

I know DOS and cmd prompt DOES NOT LIKE spaces in folder names. Your code starts with

cd c:\Program files\IIS Express

and it's trying to go to c:\Program in stead of C:\"Program Files"

Change the folder name and *.exe name. Hope this helps

Update: Leaving this answer for historical reasons, but I don't recommend it. Please see the accepted answer above.

Tell Jackson to map using your custom [de]serialization classes:

@JsonSerialize(using = LocalDateTimeSerializer.class)
@JsonDeserialize(using = LocalDateTimeDeserializer.class)
private LocalDateTime ignoreUntil;

provide custom classes:

public class LocalDateTimeSerializer extends JsonSerializer<LocalDateTime> {
    @Override
    public void serialize(LocalDateTime arg0, JsonGenerator arg1, SerializerProvider arg2) throws IOException {
        arg1.writeString(arg0.toString());
    }
}

public class LocalDateTimeDeserializer extends JsonDeserializer<LocalDateTime> {
    @Override
    public LocalDateTime deserialize(JsonParser arg0, DeserializationContext arg1) throws IOException {
        return LocalDateTime.parse(arg0.getText());
    }
}

random fact: if i nest above classes and don't make them static, the error message is weird: org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/json;charset=UTF-8' not supported

In addition to the simple addition shown by others, you can also use seq.Date or seq.POSIXt to find other increments or decrements (the POSIXt version does seconds, minutes, hours, etc.):

> seq.Date( Sys.Date(), length=2, by='3 months' )[2]
[1] "2012-07-25"
