I also faced the same problem but my case was a bit different the ones above. I tried to open a project created in a different computer. I found that the path to package folder is not updated when you add a reference so restarting VS, changing .NET version, or any mentioned recommendation does not solve the problem. I opened the csproj file in notepad++ and corrected all the relative paths to packages folder. Then; all the warnings are gone. Hope it helps.

htmlspecialchars() is perfectly adequate for filtering user input that is displayed in html forms.

I've found a way to pass parent data to component scope in Vue, i think it's a little a bit of a hack but maybe this will help you.

1) Reference data in Vue Instance as an external object (data : dataObj)

2) Then in the data return function in the child component just return parentScope = dataObj and voila. Now you cann do things like {{ parentScope.prop }} and will work like a charm.

Good Luck!

For default tooltip behavior simply add the title attribute. This can't contain images though.

<div title="regular tooltip">Hover me</div>

Before you clarified the question I did this up in pure JavaScript, hope you find it useful. The image will pop up and follow the mouse.

jsFiddle

JavaScript

var tooltipSpan = document.getElementById('tooltip-span');

window.onmousemove = function (e) {
    var x = e.clientX,
        y = e.clientY;
    tooltipSpan.style.top = (y + 20) + 'px';
    tooltipSpan.style.left = (x + 20) + 'px';
};

CSS

.tooltip span {
    display:none;
}
.tooltip:hover span {
    display:block;
    position:fixed;
    overflow:hidden;
}

Extending for multiple elements

One solution for multiple elements is to update all tooltip span's and setting them under the cursor on mouse move.

jsFiddle

var tooltips = document.querySelectorAll('.tooltip span');

window.onmousemove = function (e) {
    var x = (e.clientX + 20) + 'px',
        y = (e.clientY + 20) + 'px';
    for (var i = 0; i < tooltips.length; i++) {
        tooltips[i].style.top = y;
        tooltips[i].style.left = x;
    }
};

With flexbox this is easy:

FIDDLE

Just add the following to the image container:

.img-container {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    display: flex; /* add */
    justify-content: center; /* add to align horizontal */
    align-items: center; /* add to align vertical */
}

using flexbox:

h2 {
    display: flex;
    align-items: center;

}

h2 span {
    content:"";
    flex: 1 1 auto;
    border-top: 1px solid #000;
}

html:

<h2>Title <span></span></h2>

Converting to str is definitely slower then dividing by 10.

map is sligthly slower than list comprehension:

convert to string with map 2.13599181175
convert to string with list comprehension 1.92812991142
modulo, division, recursive 0.948769807816
modulo, division 0.699964046478

These times were returned by the following code on my laptop:

foo = """\
def foo(limit):
    return sorted(set(map(sum, map(lambda x: map(int, list(str(x))), map(lambda x: x * 9, range(limit))))))

foo(%i)
"""

bar = """\
def bar(limit):
    return sorted(set([sum([int(i) for i in str(n)]) for n in [k *9 for k in range(limit)]]))

bar(%i)
"""

rac = """\
def digits(n):
    return [n] if n<10 else digits(n / 10)+[n %% 10]

def rabbit(limit):
    return sorted(set([sum(digits(n)) for n in [k *9 for k in range(limit)]]))

rabbit(%i)
"""

rab = """\
def sum_digits(number):
  result = 0
  while number:
    digit = number %% 10
    result += digit
    number /= 10
  return result

def rabbit(limit):
    return sorted(set([sum_digits(n) for n in [k *9 for k in range(limit)]]))

rabbit(%i)
"""


import timeit

print "convert to string with map", timeit.timeit(foo % 100, number=10000)
print "convert to string with list comprehension", timeit.timeit(bar % 100, number=10000)
print "modulo, division, recursive", timeit.timeit(rac % 100, number=10000)
print "modulo, division", timeit.timeit(rab % 100, number=10000)

If the strings are the same length, then I would go for '%x' % () of the built-in xor (^).

Examples -

>>>a = '290b6e3a'
>>>b = 'd6f491c5'
>>>'%x' % (int(a,16)^int(b,16))
'ffffffff'
>>>c = 'abcd'
>>>d = '12ef'
>>>'%x' % (int(a,16)^int(b,16))
'b922'

If the strings are not the same length, truncate the longer string to the length of the shorter using a slice longer = longer[:len(shorter)]

<iframe src="hello.html" sandbox="allow-same-origin"
        onload="this.style.height=(this.contentWindow.document.body.scrollHeight+20)+'px';this.style.width=(this.contentWindow.document.body.scrollWidth+20)+'px';">
</iframe>

If the code for your jar library is on GitHub then importing into Android Studio is easy with JitPack.

Your will just need to add the repository to build.gradle:

allprojects{
 repositories {
    jcenter()
    maven { url "https://jitpack.io" }
 }
}

and then the library's GitHub repository as a dependency:

dependencies {
    // ...
    compile 'com.github.YourUsername:LibraryRepo:ReleaseTag'
}

JitPack acts as a maven repository and can be used like Maven Central. The nice thing is that you don't have to upload the jar manually. Behind the scenes JitPack will check out the code from GitHub and compile it. Therefore it works only if the repo has a build file in it (build.gradle).

There is also a guide on how to prepare an Android project.

From the documentation:

If the pattern does not contain a slash /, git treats it as a shell glob pattern and checks for a match against the pathname relative to the location of the .gitignore file (relative to the toplevel of the work tree if not from a .gitignore file).

A leading slash matches the beginning of the pathname. For example, "/*.c" matches "cat-file.c" but not "mozilla-sha1/sha1.c".

So you should add the following line to your root .gitignore:

/config.php

Adding to @HYRY's answer in1d seems to be fastest for numpy. This is using numpy 1.8 and python 2.7.6.

In this test in1d was fastest, however 10 in a look cleaner:

a = arange(0,99999,3)
%timeit 10 in a
%timeit in1d(a, 10)

10000 loops, best of 3: 150 µs per loop
10000 loops, best of 3: 61.9 µs per loop

Constructing a set is slower than calling in1d, but checking if the value exists is a bit faster:

s = set(range(0, 99999, 3))
%timeit 10 in s

10000000 loops, best of 3: 47 ns per loop

Case sensitive: document.getElementById (notice the capital B).

As my experience, you can add another domain which listens different port than 7001, and use this domain in to deploy app.

Here's an example: http://st-curriculum.oracle.com/obe/fmw/wls/10g/r3/installconfig/install_wls/install_wls.htm

Zxing is an excellent library to perform Qr code scanning and generation. The following implementation uses Zxing library to scan the QR code image Don't forget to add following dependency in the build.gradle

implementation 'me.dm7.barcodescanner:zxing:1.9'

Code scanner activity:

    public class QrCodeScanner extends AppCompatActivity implements ZXingScannerView.ResultHandler {
        private ZXingScannerView mScannerView;

        @Override
        public void onCreate(Bundle state) {
            super.onCreate(state);
            // Programmatically initialize the scanner view
            mScannerView = new ZXingScannerView(this);
            // Set the scanner view as the content view
            setContentView(mScannerView);
        }

        @Override
        public void onResume() {
            super.onResume();
            // Register ourselves as a handler for scan results.
            mScannerView.setResultHandler(this);
            // Start camera on resume
            mScannerView.startCamera();
        }

        @Override
        public void onPause() {
            super.onPause();
            // Stop camera on pause
            mScannerView.stopCamera();
        }

        @Override
        public void handleResult(Result rawResult) {
            // Do something with the result here
            // Prints scan results
            Logger.verbose("result", rawResult.getText());
            // Prints the scan format (qrcode, pdf417 etc.)
            Logger.verbose("result", rawResult.getBarcodeFormat().toString());
            //If you would like to resume scanning, call this method below:
            //mScannerView.resumeCameraPreview(this);
            Intent intent = new Intent();
            intent.putExtra(AppConstants.KEY_QR_CODE, rawResult.getText());
            setResult(RESULT_OK, intent);
            finish();
        }
    }

Try this: http://jsbin.com/axaler/3/edit

$(function(){
  $(window).scroll(function(){
    var aTop = $('.ad').height();
    if($(this).scrollTop()>=aTop){
        alert('header just passed.');
        // instead of alert you can use to show your ad
        // something like $('#footAd').slideup();
    }
  });
});

git reset --hard <old-commit-id>
git push -f <remote-name> <branch-name>

Note: As written in comments below, Using this is dangerous in a collaborative environment: you're rewriting history

It seems your hesitation is in creating your own component and then dispatching in the render method? Well you can avoid both by just using the render method of the <Route> component. No need to create a <AuthenticatedRoute> component unless you really want to. It can be as simple as below. Note the {...routeProps} spread making sure you continue to send the properties of the <Route> component down to the child component (<MyComponent> in this case).

<Route path='/someprivatepath' render={routeProps => {

   if (!this.props.isLoggedIn) {
      this.props.redirectToLogin()
      return null
    }
    return <MyComponent {...routeProps} anotherProp={somevalue} />

} />

See the React Router V4 render documentation

If you did want to create a dedicated component, then it looks like you are on the right track. Since React Router V4 is purely declarative routing (it says so right in the description) I do not think you will get away with putting your redirect code outside of the normal component lifecycle. Looking at the code for React Router itself, they perform the redirect in either componentWillMount or componentDidMount depending on whether or not it is server side rendering. Here is the code below, which is pretty simple and might help you feel more comfortable with where to put your redirect logic.

import React, { PropTypes } from 'react'

/**
 * The public API for updating the location programatically
 * with a component.
 */
class Redirect extends React.Component {
  static propTypes = {
    push: PropTypes.bool,
    from: PropTypes.string,
    to: PropTypes.oneOfType([
      PropTypes.string,
      PropTypes.object
    ])
  }

  static defaultProps = {
    push: false
  }

  static contextTypes = {
    router: PropTypes.shape({
      history: PropTypes.shape({
        push: PropTypes.func.isRequired,
        replace: PropTypes.func.isRequired
      }).isRequired,
      staticContext: PropTypes.object
    }).isRequired
  }

  isStatic() {
    return this.context.router && this.context.router.staticContext
  }

  componentWillMount() {
    if (this.isStatic())
      this.perform()
  }

  componentDidMount() {
    if (!this.isStatic())
      this.perform()
  }

  perform() {
    const { history } = this.context.router
    const { push, to } = this.props

    if (push) {
      history.push(to)
    } else {
      history.replace(to)
    }
  }

  render() {
    return null
  }
}

export default Redirect

http://swftools.org/ these guys have a pdf2swf component. They are also able to show tables. They are also giving the source. So you could possibly check it out.

only working solution for me:

put it on the bottom of build.gradle

com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true

The accepted answer being said, It is missing some explanations. For example, what is the difference between a uni-directional and a bi-directional association? In the provided example, both do exist. ( Both '5's in the arrows)

If looking for a more complete answer and have more time, here is a thorough explanation.

I had the same issue on windows. I switched from SSH to HTTPS and ran a Git PUSH.

git push -u origin master
Username for 'https://github.com': <Github login email>
Password for <Github login>: xxx

Successful! hope this helps.

CSS transformations create a new stacking context and containing block, as described in the spec. In plain English, this means that fixed position elements with a transformation applied to them will act more like absolutely positioned elements, and z-index values are likely to get screwed with.

If you take a look at this demo, you'll see what I mean. The second div has a transformation applied to it, meaning that it creates a new stacking context, and the pseudo elements are stacked on top rather than below.

So basically, don't do that. Apply a 3D transformation only when you need the optimization. -webkit-font-smoothing: antialiased; is another way to tap into 3D acceleration without creating these problems, but it only works in Safari.

You can set up your element with

value="@model.productId"

and

onclick= addToWishList(this.value);

To iterate over a multidimensional array, you can use RecursiveArrayIterator

$jsonIterator = new RecursiveIteratorIterator(
    new RecursiveArrayIterator(json_decode($json, TRUE)),
    RecursiveIteratorIterator::SELF_FIRST);

foreach ($jsonIterator as $key => $val) {
    if(is_array($val)) {
        echo "$key:\n";
    } else {
        echo "$key => $val\n";
    }
}

Output:

John:
status => Wait
Jennifer:
status => Active
James:
status => Active
age => 56
count => 10
progress => 0.0029857
bad => 0

run on codepad

import java.lang.String; //contains equalsIgnoreCase()
/*
*
*/
String s1 = "Hello";
String s2 = "hello";

if (s1.equalsIgnoreCase(s2)) {
System.out.println("hai");
} else {
System.out.println("welcome");
}

Now it will output : hai

If you have "something" and need 'something', use replace(col, "\"", "\'") and viceversa.

Suppose

a = ['a', 'b', 'c', 3, 4, 'd', 6, 7, 8]

and the list of indexes is stored in

b= [0, 1, 2, 4, 6, 7, 8]

then a simple one-line solution will be

c = [a[i] for i in b]

• DOM presents the xml document as a the following tree-structure in memory.
• DOM is W3C standard.
• DOM parser works on Document Object Model.
• DOM occupies more memory, preferred for small XML documents
• DOM is Easy to navigate either forward or backward.

• SAX presents the xml document as event based like start element:abc, end element:abc.
• SAX is not W3C standard, it was developed by group of developers.
• SAX does not use memory, preferred for large XML documents.
• Backward navigation is not possible as it sequentially process the documents.
• Event happens to a node/element and it gives all sub nodes(Latin nodus, ‘knot’).

This XML document, when passed through a SAX parser, will generate a sequence of events like the following:

start element: bookstore
start element: book with an attribute category equal to cooking
start element: title with an attribute lang equal to en
Text node, with data equal to Everyday Italian
....
end element: title
.....
end element: book
end element: bookstore

I have used the following code in the past and it had worked with basic authentication enabled in TomCat:

URL myURL = new URL(serviceURL);
HttpURLConnection myURLConnection = (HttpURLConnection)myURL.openConnection();

String userCredentials = "username:password";
String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userCredentials.getBytes()));

myURLConnection.setRequestProperty ("Authorization", basicAuth);
myURLConnection.setRequestMethod("POST");
myURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
myURLConnection.setRequestProperty("Content-Length", "" + postData.getBytes().length);
myURLConnection.setRequestProperty("Content-Language", "en-US");
myURLConnection.setUseCaches(false);
myURLConnection.setDoInput(true);
myURLConnection.setDoOutput(true);

You can try the above code. The code above is for POST, and you can modify it for GET

Hopefully someone else is saved by reading this.

We encountered an issue with webkit based browsers doing:

window.open("webpage.htm", "_self");

The browser would lockup and die if we had too many DOM nodes. When we switched our code to following the accepted answer of:

location.href = "webpage.html";

all was good. It took us awhile to figure out what was causing the issue, since it wasn't obvious what made our page periodically fail to load.

You must have the definition of class B before you use the class. How else would the compiler otherwise know that there exists such a function as B::add?

Either define class B before class A, or move the body of A::doSomething to after class B have been defined, like

class B;

class A
{
    B* b;

    void doSomething();
};

class B
{
    A* a;

    void add() {}
};

void A::doSomething()
{
    b->add();
}

The entry point for Java programs is the method:

public static void main(String[] args) {
    //Code
}

If you do not have this, your program will not run.

Worked fine:

1- install nodemailer, package if not installed (type in cmd) : npm install nodemailer

2- go to https://myaccount.google.com/lesssecureapps and turn on Allow less secure apps.

3- write code:

var nodemailer = require('nodemailer');

var transporter = nodemailer.createTransport({
    service: 'gmail',
    auth: {
        user: '[email protected]',
        pass: 'truePassword'
    }
});

const mailOptions = {
    from: '[email protected]', // sender address
    to: '[email protected]', // list of receivers
    subject: 'test mail', // Subject line
    html: '<h1>this is a test mail.</h1>'// plain text body
};

transporter.sendMail(mailOptions, function (err, info) {
    if(err)
        console.log(err)
    else
        console.log(info);
})

4- enjoy!

You can use compileall in the terminal. The following command will go recursively into sub directories and make pyc files for all the python files it finds. The compileall module is part of the python standard library, so you don't need to install anything extra to use it. This works exactly the same way for python2 and python3.

python -m compileall .

Today, I tried a lot and I couldn't delete live app so what I follow.

1. I created a new version ex. 1.1 (which was actually not needed)
2. Go to -> Pricing and Availability
3. Scroll to the bottom
4. Availability -> Click On Remove from Sale.
5. Click on Yes on pop and that will removed with Status "Developer removed from Sale"

Note: Make sure you have rights like Admin/Manager to delete that App.

If you're testing for all zeros to avoid a warning on another numpy function then wrapping the line in a try, except block will save having to do the test for zeros before the operation you're interested in i.e.

try: # removes output noise for empty slice 
    mean = np.mean(array)
except:
    mean = 0

Either attribute can be applied to View's (visual control) horizontal or vertical size. It's used to set a View or Layouts size based on either it's contents or the size of it's parent layout rather than explicitly specifying a dimension.

fill_parent (deprecated and renamed MATCH_PARENT in API Level 8 and higher)

Setting the layout of a widget to fill_parent will force it to expand to take up as much space as is available within the layout element it's been placed in. It's roughly equivalent of setting the dockstyle of a Windows Form Control to Fill.

Setting a top level layout or control to fill_parent will force it to take up the whole screen.

wrap_content

Setting a View's size to wrap_content will force it to expand only far enough to contain the values (or child controls) it contains. For controls -- like text boxes (TextView) or images (ImageView) -- this will wrap the text or image being shown. For layout elements it will resize the layout to fit the controls / layouts added as its children.

It's roughly the equivalent of setting a Windows Form Control's Autosize property to True.

There's some details in the Android code documentation here.

I tried a number of methods before discovering git push --mirror.

Worked like a charm!

In linguistics, to divide language into small components that can be analyzed. For example, parsing this sentence would involve dividing it into words and phrases and identifying the type of each component (e.g.,verb, adjective, or noun).

Parsing is a very important part of many computer science disciplines. For example, compilers must parse source code to be able to translate it into object code. Likewise, any application that processes complex commands must be able to parse the commands. This includes virtually all end-user applications.

Parsing is often divided into lexical analysis and semantic parsing. Lexical analysis concentrates on dividing strings into components, called tokens, based on punctuationand other keys. Semantic parsing then attempts to determine the meaning of the string.

To fix this, we had to changed the AppPool Identity to an administrator account.

Choose the build

The answer is that you Mouse over the icon for your build and at the end of the line you'll see a little colored minus in a circle. This removes the build and you can now click on the + sign and choose a new build for submitting.

It is an unbelievably complicated web page with tricks and gizmos to do the thing you want. I'm sure Steve never saw this page or tried to use it.

Surely it's better practice to design the screen so that you can see the options all the time, not to have the screen change depending on whether you have an app in review or not!

I know how to create a custom row + custom array adapter to support a custom row for the entire list view. But how can one listview support many different row styles?

You already know the basics. You just need to get your custom adapter to return a different layout/view based on the row/cursor information being provided.

A ListView can support multiple row styles because it derives from AdapterView:

An AdapterView is a view whose children are determined by an Adapter.

If you look at the Adapter, you'll see methods that account for using row-specific views:

abstract int getViewTypeCount()
// Returns the number of types of Views that will be created ...

abstract int getItemViewType(int position)
// Get the type of View that will be created ...

abstract View getView(int position, View convertView, ViewGroup parent)
// Get a View that displays the data ...

The latter two methods provide the position so you can use that to determine the type of view you should use for that row.

Of course, you generally don't use AdapterView and Adapter directly, but rather use or derive from one of their subclasses. The subclasses of Adapter may add additional functionality that change how to get custom layouts for different rows. Since the view used for a given row is driven by the adapter, the trick is to get the adapter to return the desired view for a given row. How to do this differs depending on the specific adapter.

For example, to use ArrayAdapter,

• override getView() to inflate, populate, and return the desired view for the given position. The getView() method includes an opportunity reuse views via the convertView parameter.

But to use derivatives of CursorAdapter,

• override newView() to inflate, populate, and return the desired view for the current cursor state (i.e. the current "row") [you also need to override bindView so that widget can reuse views]

However, to use SimpleCursorAdapter,

• define a SimpleCursorAdapter.ViewBinder with a setViewValue() method to inflate, populate, and return the desired view for a given row (current cursor state) and data "column". The method can define just the "special" views and defer to SimpleCursorAdapter's standard behavior for the "normal" bindings.

Look up the specific examples/tutorials for the kind of adapter you end up using.

A console application does not automatically add a reference to System.Windows.Forms.dll.

Right-click your project in Solution Explorer and select Add reference... and then find System.Windows.Forms and add it.

You can always simply add an alert() prompt anywhere in a function. Especially useful for knowing if a function was called, if a function completed or where a function fails.

alert('start of function x');
alert('end of function y');
alert('about to call function a');
alert('returned from function b');

You get the idea.

private Toolbar toolbar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    toolbar = (Toolbar) findViewById(R.id.my_toolbar);
    *// here is where you set it to show on the toolbar*
    setSupportActionBar(toolbar);
}

Well, you need to set support action bar setSupportActionBar(); and pass your variable, like so: setSupportActionBar(toolbar);

driver.findElement(By.id("invoice_supplier_id")).setAttribute("value", "your value");

Do this instead:

<table width="100%" border="0" cellpadding="0" cellspacing="0">
  <tr>
      <td bgcolor="#7d9aaa" width="40%" style="color: #ffffff; font-size:15px; font-family:Arial, Helvetica, sans-serif; font-weight: bold; padding:12px;">
        Order Confirmation
      </td>
      <td bgcolor="#7d9aaa" align="right" width="60%" style="color: #ffffff; font-size:15px; font-family:Arial, Helvetica, sans-serif; font-weight: bold; padding:12px;">
        Your Confirmation number is {{var order.increment_id}}
      </td>
  </tr>
</table>

It is better to use two cells and align the content, than using large padding and  's.

What about this:

new ImageBrush(new BitmapImage(new Uri(BaseUriHelper.GetBaseUri(this), "Images/icon.png")))

or alternatively, this:

this.Background = new ImageBrush(new BitmapImage(new Uri(@"pack://application:,,,/myapp;component/Images/icon.png")));

This answer extends on Jayson's excellent answer with some more opinionated guidance on the best approach for your use case:

• SDKMAN is the best solution for most users. It's easy to use, doesn't have any weird configuration, and makes managing multiple versions for lots of other Java ecosystem projects easy as well.
• Downloading Java versions via Homebrew and switching versions via jenv is a good option, but requires more work. For example, the Homebrew commands in this highly upvoted answer don't work anymore. jenv is slightly harder to setup, the plugins aren't well documented, and the README says the project is looking for a new maintainer. jenv is still a great project, solves the job, and the community should be thankful for the wonderful contribution. SDKMAN is just the better option cause it's so great.
• Jabba is written is a multi-platform solution that provides the same interface on Mac, Windows, and PC (it's written in Go and that's what allows it to be multiplatform). If you care about a multiplatform solution, this is a huge selling point. If you only care about running multiple versions on your Mac, then you don't need a multiplatform solution. SDKMAN's support for tens of popular SDKs is what you're missing out on if you go with Jabba.

Managing versions manually is probably the worst option. If you decide to manually switch versions, you can use this Bash code instead of Jayson's verbose code (code snippet from the homebrew-openjdk README:

jdk() {
        version=$1
        export JAVA_HOME=$(/usr/libexec/java_home -v"$version");
        java -version
 }

Jayson's answer provides the basic commands for SDKMAN and jenv. Here's more info on SDKMAN and more info on jenv if you'd like more background on these tools.

your break statement should break out of the for (in in 1:n).

Personally I am always wary with break statements and double check it by printing to the console to double check that I am in fact breaking out of the right loop. So before you test add the following statement, which will let you know if you break before it reaches the end. However, I have no idea how you are handling the variable n so I don't know if it would be helpful to you. Make a n some test value where you know before hand if it is supposed to break out or not before reaching n.

for (in in 1:n)
{
    if (in == n)         #add this statement
    {
        "sorry but the loop did not break"
    }

    id_novo <- new_table_df$ID[in]
    if(id_velho==id_novo)
    {
        break
    }
    else if(in == n)
    {
        sold_df <- rbind(sold_df,old_table_df[out,])
    }
}

I'm going to take a stab in the dark and guess you're talking about Windows. In a nutshell, kernel mode has full access to hardware, but user mode doesn't. For instance, many if not most device drivers are written in kernel mode because they need to control finer details of their hardware.

See also this wikibook.

Using Collections#addAll()

String[] words = {"ace","boom","crew","dog","eon"};
List<String> arrayList = new ArrayList<>(); 
Collections.addAll(arrayList, words); 

>>> 'QH QD JC KD JS'.split()
['QH', 'QD', 'JC', 'KD', 'JS']

split:

Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most maxsplit+1 elements). If maxsplit is not specified, then there is no limit on the number of splits (all possible splits are made).

If sep is given, consecutive delimiters are not grouped together and are deemed to delimit empty strings (for example, '1,,2'.split(',') returns ['1', '', '2']). The sep argument may consist of multiple characters (for example, '1<>2<>3'.split('<>') returns ['1', '2', '3']). Splitting an empty string with a specified separator returns [''].

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace. Consequently, splitting an empty string or a string consisting of just whitespace with a None separator returns [].

For example, ' 1 2 3 '.split() returns ['1', '2', '3'], and ' 1 2 3 '.split(None, 1) returns ['1', '2 3 '].

You can use DDC (Domain Directory Controller). It is a new, easy to use, Java SDK. You don't even need to know LDAP to use it. It exposes an object-oriented API instead.

You can find it here.

You can do this in Kotlin by creating a class that extends Application and then use its context to call the resources anywhere in your code

Your App class will look like this

 class App : Application() {
    override fun onCreate() {
        super.onCreate()
        context = this
    }

    companion object {
        var context: Context? = null
            private set
    }
}

Declare your Application class in AndroidManifest.xml (very important)

<application
        android:allowBackup="true"
        android:name=".App" //<--Your declaration Here
        ...>
        <activity
            android:name=".SplashActivity"  android:theme="@style/SplashTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity android:name=".MainActivity"/>
    </application>

To access e.g. a string file use the following code

App.context?.resources?.getText(R.string.mystring)

Yes, but then what do you do about the django objects? simple json tends to choke on them.

If the objects are individual model objects (not querysets, e.g.), I have occasionally stored the model object type and the pk, like so:

seralized_dict = simplejson.dumps(my_dict, 
                     default=lambda a: "[%s,%s]" % (str(type(a)), a.pk)
                     )

to de-serialize, you can reconstruct the object referenced with model.objects.get(). This doesn't help if you are interested in the object details at the type the dict is stored, but it's effective if all you need to know is which object was involved.

public class SimpleObjectDictionaryMapper<TObject>
{
    public static TObject GetObject(IDictionary<string, object> d)
    {
        PropertyInfo[] props = typeof(TObject).GetProperties();
        TObject res = Activator.CreateInstance<TObject>();
        for (int i = 0; i < props.Length; i++)
        {
            if (props[i].CanWrite && d.ContainsKey(props[i].Name))
            {
                props[i].SetValue(res, d[props[i].Name], null);
            }
        }
        return res;
    }

    public static IDictionary<string, object> GetDictionary(TObject o)
    {
        IDictionary<string, object> res = new Dictionary<string, object>();
        PropertyInfo[] props = typeof(TObject).GetProperties();
        for (int i = 0; i < props.Length; i++)
        {
            if (props[i].CanRead)
            {
                res.Add(props[i].Name, props[i].GetValue(o, null));
            }
        }
        return res;
    }
}

The print statement in Python converts its arguments to strings, and outputs those strings to stdout. To save the string to a variable instead, only convert it to a string:

a = str(tag.getArtist())

Problems only surface when I am I trying to give the first loaded content an active state

Does this mean that you want to add a class to the first button?

$('.o-links').click(function(e) {   // ... }).first().addClass('O_Nav_Current'); 

instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:

CSS:

.image-area {     width: 100%;     height: auto;     display: none; }  .image-area:first-of-type {     display: block; } 

JavaScript:

var $slides = $('.image-area'),     $btns = $('a.o-links');  $btns.on('click', function (e) {     var i = $btns.removeClass('O_Nav_Current').index(this);     $(this).addClass('O_Nav_Current');      $slides.filter(':visible').fadeOut(1000, function () {         $slides.eq(i).fadeIn(1000);     });      e.preventDefault();  }).first().addClass('O_Nav_Current'); 

http://jsfiddle.net/RmF57/

You are calling setTimeout() ten times in a row, so they all expire almost at the same time. What you actually want is this:

window.onload = function start() {
    slide(10);
}
function slide(repeats) {
    if (repeats > 0) {
        document.getElementById('container').style.marginLeft='-600px';
        document.getElementById('container').style.marginLeft='-1200px';
        document.getElementById('container').style.marginLeft='-1800px';
        document.getElementById('container').style.marginLeft='0px';
        window.setTimeout(
          function(){
            slide(repeats - 1)
          },
          3000
        );
    }
}

This will call slide(10), which will then set the 3-second timeout to call slide(9), which will set timeout to call slide(8), etc. When slide(0) is called, no more timeouts will be set up.

This usually happens when the repo is cloned between Windows and Linux/Unix machines.

Just tell git to ignore filemode change. Here are several ways to do so:

1. Config ONLY for current repo:

    git config core.filemode false
   

2. Config globally:

    git config --global core.filemode false
   

3. Add in ~/.gitconfig:

    [core]
         filemode = false
   

Just select one of them.

Now you can do (not sure if it's the same answer as evilpie):

MyObject = type('MyObject', (object,), {})
obj = MyObject()
obj.value = 42

For typescript cast to KeyboardEventInit and provide the correct keyCode integer

const event = new KeyboardEvent("keydown", {
          keyCode: 38,
        } as KeyboardEventInit);

Simple and efficient solution to get a random 10 characters string with uppercase and lowercase letters and digits :

select substring(base64_encode(md5(rand())) from 1+rand()*4 for 10);

Look at Compare-Object

Compare-Object $a1 $b1 | ForEach-Object { $_.InputObject }

Or if you would like to know where the object belongs to, then look at SideIndicator:

$a1=@(1,2,3,4,5,8)
$b1=@(1,2,3,4,5,6)
Compare-Object $a1 $b1

If your console supports ANSI colour codes (e.g. ConEmu, Clink or ANSICON) you can do this:

SET    GRAY=%ESC%[0m
SET     RED=%ESC%[1;31m
SET   GREEN=%ESC%[1;32m
SET  ORANGE=%ESC%[0;33m
SET    BLUE=%ESC%[0;34m
SET MAGENTA=%ESC%[0;35m
SET    CYAN=%ESC%[1;36m
SET   WHITE=%ESC%[1;37m

where ESC variable contains ASCII character 27.

I found a way to populate the ESC variable here: http://www.dostips.com/forum/viewtopic.php?p=6827#p6827 and using tasklist it's possible to test what DLLs are loaded into a process.

The following script gets the process ID of the cmd.exe that the script is running in. Checks if it has a dll that will add ANSI support injected, and then sets colour variables to contain escape sequences or be empty depending on whether colour is supported or not.

Connection Timeout=30 means that the database server has 30 seconds to establish a connection.

Connection Timeout specifies the time limit (in seconds), within which the connection to the specified server must be made, otherwise an exception is thrown i.e. It specifies how long you will allow your program to be held up while it establishes a database connection.

DataSource=server;
InitialCatalog=database;
UserId=username;
Password=password;
Connection Timeout=30

SqlConnection.ConnectionTimeout. specifies how many seconds the SQL Server service has to respond to a connection attempt. This is always set as part of the connection string.

Notes:

• The value is expressed in seconds, not milliseconds.

• The default value is 30 seconds.

• A value of 0 means to wait indefinitely and never time out.

In addition, SqlCommand.CommandTimeout specifies the timeout value of a specific query running on SQL Server, however this is set via the SqlConnection object/setting (depending on your programming language), and not in the connection string i.e. It specifies how long you will allow your program to be held up while the command is run.

Solution is to make JAVA_HOME == dir above bin where javac lives as in

type javac

javac is /usr/bin/javac   # now check if its just a symlink

ls -la /usr/bin/javac 

/usr/bin/javac -> /etc/alternatives/javac   # its a symlink so check again

ls -la /etc/alternatives/javac  # now check if its just a symlink

/etc/alternatives/javac -> /usr/lib/jvm/java-8-openjdk-amd64/bin/javac

OK so finally found the bin above actual javac so do this

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH

above can be simplified and generalized to

which javac >/dev/null 2>&1 || die "ERROR: no 'javac' command could be found in your PATH"
export JAVA_HOME=$(dirname $(dirname $(readlink -f $(which javac)  )))

In order to use mod_rewrite you can type the following command in the terminal:

 $ su

 $ passwd **********

 # a2enmod rewrite

Restart apache2 after

 # service apache2 restart

 # /etc/init.d/apache2 restart

or

 # service apache2 restart

Mark, this is already answered in your previous topic. But OK, here it is again:

Suppose ${list} points to a List<Object>, then the following

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

does basically the same as as following in "normal Java":

for (Object item : list) {
    System.out.println(item);
}

If you have a List<Map<K, V>> instead, then the following

<c:forEach items="${list}" var="map">
    <c:forEach items="${map}" var="entry">
        ${entry.key}<br>
        ${entry.value}<br>
    </c:forEach>
</c:forEach>

does basically the same as as following in "normal Java":

for (Map<K, V> map : list) {
    for (Entry<K, V> entry : map.entrySet()) {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }
}

The key and value are here not special methods or so. They are actually getter methods of Map.Entry object (click at the blue Map.Entry link to see the API doc). In EL (Expression Language) you can use the . dot operator to access getter methods using "property name" (the getter method name without the get prefix), all just according the Javabean specification.

That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".

If you are going to do it in pure CSS (using scss) but you have different elements/classes inside the same parent class you can use this version!!

  &:first-of-type:nth-last-of-type(1) {
    max-width: 100%;
  }

  @for $i from 2 through 10 {
    &:first-of-type:nth-last-of-type(#{$i}),
    &:first-of-type:nth-last-of-type(#{$i}) ~ & {
      max-width: (100% / #{$i});
    }
  }

use desc tablename from Hive CLI or beeline to get all the column names. If you want the column names in a file then run the below command from the shell.

$ hive -e 'desc dbname.tablename;' > ~/columnnames.txt

where dbname is the name of the Hive database where your table is residing You can find the file columnnames.txt in your root directory.

$cd ~

On Ubuntu system, I purged the PostgreSQL and re-installed it. All the databases are restored. This solved the problem for me.

Advice - Take the backup of the databases to be on the safer side.

PEP 8 defines that it is better to use the is operator when comparing singletons.

This error can surface because of following two reasons:

• There is no room in the memory to accommodate new threads.

• The number of threads exceeds the Operating System limit.

I doubt that number of thread have exceeded the limit for the java process

So possibly chances are the issue is because of memory One point to consider is

threads are not created within the JVM heap. They are created outside the JVM heap. So if there is less room left in the RAM, after the JVM heap allocation, application will run into “java.lang.OutOfMemoryError: unable to create new native thread”.

Possible Solution is to reduce the heap memory or increase the overall ram size

Here is how I got without '[' and ']' in C#:

        var text = "This is a test string [more or less]";
        //Getting only string between '[' and ']'
        Regex regex = new Regex(@"\[(.+?)\]");
        var matchGroups = regex.Matches(text);
        for (int i = 0; i < matchGroups.Count; i++)
        {
            Console.WriteLine(matchGroups[i].Groups[1]);
        }

The output is:

more or less

One possible way to count lines of code in Eclipse:

using the Search / File... menu, select File Search tab, specify \n[\s]* for Containing text (this will not count empty lines), and tick Regular expression.

I think the simplest way it's to use library ContentManager. This library for getting photo or video from a device gallery, cloud or camera. With asynchronous load from the cloud and fixed bugs for some problem devices.

Download via Gradle: compile 'com.github.stfalcon:contentmanager:0.4.3' You can find documentation at https://github.com/stfalcon-studio/ContentManager

This is what I added in the CMakeList.txt (which worked):

# https://cmake.org/cmake/help/latest/command/find_package.html
# in the above link, it states:
# "In Module mode, CMake searches for a file called Find<PackageName>.cmake. 
#  The file is first searched in the CMAKE_MODULE_PATH, then among the Find 
#  Modules provided by the CMake installation. If the file is found, it is
#  read and processed by CMake. It is responsible for finding the package,
#  checking the version, and producing any needed messages. Some find-modules
#  provide limited or no support for versioning; check the module documentation."
#
# FindOpenSSL.cmake can be found in path/to/cmake/Modules
#
# https://cmake.org/cmake/help/latest/module/FindOpenSSL.html
#

find_package(OpenSSL REQUIRED)
if (OPENSSL_FOUND)
  # Add the include directories for compiling
  target_include_directories(${PROJECT_NAME} PUBLIC ${OPENSSL_INCLUDE_DIR})

  # Add the static lib for linking
  target_link_libraries(${PROJECT_NAME} OpenSSL::SSL OpenSSL::Crypto)

  message(STATUS "Found OpenSSL ${OPENSSL_VERSION}")

else()

  message(STATUS "OpenSSL Not Found")

endif()

Typically we would place one of these at or near the top of the script. Scripts that parse their command lines would do the redirection after parsing.

Send stdout to a file

exec > file

with stderr

exec > file                                                                      
exec 2>&1

append both stdout and stderr to file

exec >> file
exec 2>&1

As Jonathan Leffler mentioned in his comment:

exec has two separate jobs. The first one is to replace the currently executing shell (script) with a new program. The other is changing the I/O redirections in the current shell. This is distinguished by having no argument to exec.

The hard truth is: the only good debugger for IE is Visual Studio.

If you don't have money for the real deal, download free Visual Web Developer 2008 Express EditionVisual Web Developer 2010 Express Edition. While the former allows you to attach debugger to already running IE, the latter doesn't (at least previous versions I used didn't allow that). If this is still the case, the trick is to create a simple project with one empty web page, "run" it (it starts the browser), now navigate to whatever page you want to debug, and start debugging.

Microsoft gives away full Visual Studio on different events, usually with license restrictions, but they allow tinkering at home. Check their schedule and the list of freebies.

Another hint: try to debug your web application with other browsers first. I had a great success with Opera. Somehow Opera's emulation of IE and its bugs was pretty close, but the debugger is much better.

Try this:

Dim text As String = ""
Dim files() As String = IO.Directory.GetFiles(sFolder)

For Each sFile As String In files
    text &= IO.File.ReadAllText(sFile)
Next

1. Locate the file at /etc/mysql/my.cnf

2. Edit the file by adding the following lines:

    [mysqld]
   
    lower_case_table_names=1
   

3. sudo /etc/init.d/mysql restart

4. Run mysqladmin -u root -p variables | grep table to check that lower_case_table_names is 1 now

You might need to recreate these tables to make it work.

System.Text.Json

This can now be done using System.Text.Json which is built-in to .NET Core 3.0. It's now possible to deserialize JSON without using third-party libraries.

var json = @"{""key1"":""value1"",""key2"":""value2""}";
var values = JsonSerializer.Deserialize<Dictionary<string, string>>(json);

Also available in NuGet package System.Text.Json if using .NET Standard or .NET Framework.

You need to add the Servlet API to your classpath. In Tomcat 6.0, this is in a JAR called servlet-api.jar in Tomcat's lib folder. You can either add a reference to that JAR to the project's classpath, or put a copy of the JAR in your Eclipse project and add it to the classpath from there.

If you want to leave the JAR in Tomcat's lib folder:

• Right-click the project, click Properties.
• Choose Java Build Path.
• Click the Libraries tab
• Click Add External JARs...
• Browse to find servlet-api.jar and select it.
• Click OK to update the build path.

Or, if you copy the JAR into your project:

• Right-click the project, click Properties.
• Choose Java Build Path.
• Click Add JARs...
• Find servlet-api.jar in your project and select it.
• Click OK to update the build path.

According to this message on the GCC mailing list, you can use the file "nul" instead of /dev/null:

#include <stdio.h>

int main ()
{
    FILE* outfile = fopen ("/dev/null", "w");
    if (outfile == NULL)
    {
        fputs ("could not open '/dev/null'", stderr);
    }
    outfile = fopen ("nul", "w");
    if (outfile == NULL)
    {
        fputs ("could not open 'nul'", stderr);
    }

    return 0;
}

(Credits to Danny for this code; copy-pasted from his message.)

You can also use this special "nul" file through redirection.

String.Trim() removes all whitespace from the beginning and end of a string. To remove whitespace inside a string, or normalize whitespace, use a Regular Expression.

Yes, this is a kind of inconsistency in the language.

The "=" in myarray = "abc"; is assignment (which won't work as the array is basically a kind of constant pointer), whereas in char myarray[4] = "abc"; it's an initialization of the array. There's no way for "late initialization".

You should just remember this rule.

If you use MongoDB compass, you can use sort filed to filter,

<form action="myController/myAction" method="POST">
 <input type="text" name="valueINeed" />
 <input type="submit" value="View Report" />
</form> 

controller:

[HttpPost]
public ActionResult myAction(string valueINeed)
{
   //....

SyntaxError: Unexpected token o in JSON

This also happens when you forget to use the await keyword for a method that returns JSON data.

For example:

async function returnJSONData()
{
   return "{\"prop\": 2}";
}

var json_str = returnJSONData();
var json_obj = JSON.parse(json_str);

will throw an error because of the missing await. What is actually returned is a Promise [object], not a string.

To fix just add await as you're supposed to:

var json_str = await returnJSONData();

This should be pretty obvious, but the error is called on JSON.parse, so it's easy to miss if there's some distance between your await method call and the JSON.parse call.

Soviut's advice for lxml objectify is good. With a specially subclassed simplejson, you can turn an lxml objectify result into json.

import simplejson as json
import lxml

class objectJSONEncoder(json.JSONEncoder):
  """A specialized JSON encoder that can handle simple lxml objectify types
      >>> from lxml import objectify
      >>> obj = objectify.fromstring("<Book><price>1.50</price><author>W. Shakespeare</author></Book>")       
      >>> objectJSONEncoder().encode(obj)
      '{"price": 1.5, "author": "W. Shakespeare"}'       
 """


    def default(self,o):
        if isinstance(o, lxml.objectify.IntElement):
            return int(o)
        if isinstance(o, lxml.objectify.NumberElement) or isinstance(o, lxml.objectify.FloatElement):
            return float(o)
        if isinstance(o, lxml.objectify.ObjectifiedDataElement):
            return str(o)
        if hasattr(o, '__dict__'):
            #For objects with a __dict__, return the encoding of the __dict__
            return o.__dict__
        return json.JSONEncoder.default(self, o)

See the docstring for example of usage, essentially you pass the result of lxml objectify to the encode method of an instance of objectJSONEncoder

Note that Koen's point is very valid here, the solution above only works for simply nested xml and doesn't include the name of root elements. This could be fixed.

I've included this class in a gist here: http://gist.github.com/345559

I had same problem and found that you can just apply the [JsonIgnore] attribute to the navigation property you don't want to be serialised. It will still serialise both the parent and child entities but just avoids the self referencing loop.

Try using OPENDATASOURCE The syntax is like this:

select * from OPENDATASOURCE ('SQLNCLI', 'Data Source=192.168.6.69;Initial Catalog=AnotherDatabase;Persist Security Info=True;User ID=sa;Password=AnotherDBPassword;MultipleActiveResultSets=true;' ).HumanResources.Department.MyTable    

String input = "2,1,3,4,5,10,100";
String[] strings = input.split(",");
int[] numbers = new int[strings.length];
for (int i = 0; i < numbers.length; i++)
{
  numbers[i] = Integer.parseInt(strings[i]);
}
Arrays.sort(numbers);

System.out.println(Arrays.toString(numbers));

SELECT *
FROM myTable
WHERE URL = LEFT('mysyte.com/?id=2&region=0&page=1', LEN(URL))

Or use CHARINDEX http://msdn.microsoft.com/en-us/library/aa258228(v=SQL.80).aspx

The string that you pass to the constructor JSONObject has to be escaped with quote():

public static java.lang.String quote(java.lang.String string)

Your code would now be:

JSONObject jsonObj = new JSONObject.quote(jsonString.toString());
System.out.println(jsonString);
System.out.println("---------------------------");
System.out.println(jsonObj);

Use OnClientClick = "return false;"

As other comments here pointed out, you'll need to uncomment disable_overscan=1 in /boot/config.txt

if you are using NOOBS (this is what im using), you'll find in the end of the file a set of default settings that has disable_overscan=0 attribute. you'll need to change its value to 1, and re-boot.

I agree with the existing answers that the second form is better because it does not have any side effects and is easier to parallelise (just use a parallel stream).

Performance wise, it appears they are equivalent until you start using parallel streams. In that case, map will perform really much better. See below the micro benchmark results:

Benchmark                         Mode  Samples    Score   Error  Units
SO28319064.forEach                avgt      100  187.310 ± 1.768  ms/op
SO28319064.map                    avgt      100  189.180 ± 1.692  ms/op
SO28319064.mapWithParallelStream  avgt      100   55,577 ± 0,782  ms/op

You can't boost the first example in the same manner because forEach is a terminal method - it returns void - so you are forced to use a stateful lambda. But that is really a bad idea if you are using parallel streams.

Finally note that your second snippet can be written in a sligthly more concise way with method references and static imports:

myFinalList = myListToParse.stream()
    .filter(Objects::nonNull)
    .map(this::doSomething)
    .collect(toList()); 

I have fixed this in my matplotlib source, but it's not a pretty fix. However, if you, like me, are very particular about how the graph looks, it's worth it.

The issue seems to be in the rendering backends; they each get the correct values for linewidth, font size, etc., but that comes out slightly larger when rendered as a PDF or PNG than when rendered with show().

I added a few lines to the source for PNG generation, in the file matplotlib/backends/backend_agg.py. You could make similar changes for each backend you use, or find a way to make a more clever change in a single location ;)

Added to my matplotlib/backends/backend_agg.py file:

    # The top of the file, added lines 42 - 44
42  # @warning: CHANGED FROM SOURCE to draw thinner lines
43  PATH_SCALAR = .8
44  FONT_SCALAR = .95

    # In the draw_markers method, added lines 90 - 91
89  def draw_markers(self, *kl, **kw):
90      # @warning: CHANGED FROM SOURCE to draw thinner lines
91      kl[0].set_linewidth(kl[0].get_linewidth()*PATH_SCALAR)
92      return self._renderer.draw_markers(*kl, **kw)

    # At the bottom of the draw_path method, added lines 131 - 132:
130 else:
131     # @warning: CHANGED FROM SOURCE to draw thinner lines
132     gc.set_linewidth(gc.get_linewidth()*PATH_SCALAR)
133     self._renderer.draw_path(gc, path, transform, rgbFace)

    # At the bottom of the _get_agg_font method, added line 242 and the *FONT_SCALAR
241     font.clear()
242     # @warning: CHANGED FROM SOURCE to draw thinner lines
243     size = prop.get_size_in_points()*FONT_SCALAR
244     font.set_size(size, self.dpi)

So that suits my needs for now, but, depending on what you're doing, you may want to implement similar changes in other methods. Or find a better way to do the same without so many line changes!

Update: After posting an issue to the matplotlib project at Github, I was able to track down the source of my problem: I had changed the figure.dpi setting in the matplotlibrc file. If that value is different than the default, my savefig() images come out different, even if I set the savefig dpi to be the same as the figure dpi. So, instead of changing the source as above, I just kept the figure.dpi setting as the default 80, and was able to generate images with savefig() that looked like images from show().

Leon, had you also changed that setting?

If you expect to dereference the same path many times, building a function for each dot notation path actually has the best performance by far (expanding on the perf tests James Wilkins linked to in comments above).

var path = 'a.b.x';
var getter = new Function("obj", "return obj." + path + ";");
getter(obj);

Using the Function constructor has some of the same drawbacks as eval() in terms of security and worst-case performance, but IMO it's a badly underused tool for cases where you need a combination of extreme dynamism and high performance. I use this methodology to build array filter functions and call them inside an AngularJS digest loop. My profiles consistently show the array.filter() step taking less than 1ms to dereference and filter about 2000 complex objects, using dynamically-defined paths 3-4 levels deep.

A similar methodology could be used to create setter functions, of course:

var setter = new Function("obj", "newval", "obj." + path + " = newval;");
setter(obj, "some new val");

JSFiddle

Uses .each(), .replace(), .html(). Tested with jQuery 1.11 and 3.2.

In the above example, reads the 'keyword' to be highlighted and appends span tag with the 'highlight' class. The text 'keyword' is highlighted for all selected classes in the .each().

HTML

<body>
   <label name="lblKeyword" id="lblKeyword" class="highlight">keyword</label>
   <p class="filename">keyword</p>
   <p class="content">keyword</p>
   <p class="system"><i>keyword</i></p>
</body>

JS

$(document).ready(function() {
   var keyWord = $("#lblKeyword").text(); 
   var replaceD = "<span class='highlight'>" + keyWord + "</span>";
   $(".system, .filename, .content").each(function() {
      var text = $(this).text();
      text = text.replace(keyWord, replaceD);
      $(this).html(text);
   });
});

CSS

.highlight {
    background-color: yellow;
}

While it's ok to use inline styles, your purposes may better be served by including an external CSS file on the page. This way you could define a class of image (i.e. 'Thumbnail', 'Photo', 'Large', etc) and assign it a constant size. This will help when you end up with images requiring the same placement across multiple pages.

Like this:

In your header:
<link type="text/css" rel="stylesheet" href="css/style.css" />

Your HTML:
<img class="thumbnail" src="images/academia_vs_business.png" alt="" />

In css/style.css:
img.thumbnail {
   width: 75px;
   height: 75px;
}

If you'd like to use inline styles though, it's probably best to set the width and height using the style attribute for the sake of readability.

If you create a copy of the array and sort it descending, the first element of the copy will be the largest. Than you can find its index in the original array.

var sorted = [...arr].sort((a,b) => b - a)
arr.indexOf(sorted[0])

Time complexity is O(n) for the copy, O(n*log(n)) for sorting and O(n) for the indexOf.

If you need to do it faster, Ry's answer is O(n).

In order to perform chmod, you need to be owner of the file you are trying to modify, or the root user.

I know this is well after the OP. One way you can go with that keeps the table storing the zipcode data as an unsigned INT but displayed with zeros is as follows.

select LPAD(cast(zipcode_int as char), 5, '0') as zipcode from table;

While this preserves the original data as INT and can save some space in storage you will be having the server perform the INT to CHAR conversion for you. This can be thrown into a view and the person who needs this data can be directed there vs the table itself.

You can use setInterval(), the arguments are the same.

const interval = setInterval(function() {
   // method to be executed;
 }, 5000);

clearInterval(interval); // thanks @Luca D'Amico

Check out this great blog post by John Atten: ASP.NET Identity 2.0: Customizing Users and Roles

It has great step-by-step info on the whole process. Go read it : )

Here are some of the basics.

Extend the default ApplicationUser class by adding new properties (i.e.- Address, City, State, etc.):

public class ApplicationUser : IdentityUser
{
    public async Task<ClaimsIdentity> 
    GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        var userIdentity = await manager.CreateIdentityAsync(this,  DefaultAuthenticationTypes.ApplicationCookie);
        return userIdentity;
    }
    public string Address { get; set; }
    public string City { get; set; }
    public string State { get; set; }

    // Use a sensible display name for views:
    [Display(Name = "Postal Code")]
    public string PostalCode { get; set; }

    // Concatenate the address info for display in tables and such:
    public string DisplayAddress
    {
        get
        {
            string dspAddress = string.IsNullOrWhiteSpace(this.Address) ? "" : this.Address;
            string dspCity = string.IsNullOrWhiteSpace(this.City) ? "" : this.City;
            string dspState = string.IsNullOrWhiteSpace(this.State) ? "" : this.State;
            string dspPostalCode = string.IsNullOrWhiteSpace(this.PostalCode) ? "" : this.PostalCode;

            return string.Format("{0} {1} {2} {3}", dspAddress, dspCity, dspState, dspPostalCode);
        }
    }

Then you add your new properties to your RegisterViewModel.

    // Add the new address properties:
    public string Address { get; set; }
    public string City { get; set; }
    public string State { get; set; }

Then update the Register View to include the new properties.

    <div class="form-group">
        @Html.LabelFor(m => m.Address, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.Address, new { @class = "form-control" })
        </div>
    </div>

Then update the Register() method on AccountController with the new properties.

    // Add the Address properties:
    user.Address = model.Address;
    user.City = model.City;
    user.State = model.State;
    user.PostalCode = model.PostalCode;

Version 12.5 of wkhtmltopdf only lists DEB files on their download page now. Being a mac user and not knowing much linux or what DEB files were I couldn't use the solutions posted.

This page helped me get past the knew twist of downloading a DEB file: http://www.g-loaded.eu/2008/01/28/how-to-extract-rpm-or-deb-packages/

Basically what I did was:

1. Downloaded from https://wkhtmltopdf.org/downloads.html
2. Unzipped the DEB file.
3. Unzipped data.tar.xz
4. Uploaded the binary in the unzipped 'usr' folder from step 3 (usr/local/bin/wkhtmltopdf)

Then I found out that the 'exec' function was disabled on my host. So make sure you can specifically run 'exec' if you're using PHP to run this. "Can I run the wkhtmltopdf binary" isn't specific enough. My fault.

Have you tried JQuery? Vanilla javascript can be tough. Try using this:

$('.container-element').add('<div>Insert Div Content</div>');

.container-element is a JQuery selector that marks the element with the class "container-element" (presumably the parent element in which you want to insert your divs). Then the add() function inserts HTML into the container-element.

Everything that other solutions have, but with a little validation

// value = '675-805-714'
const validateNumberInput = (value) => { 
    let numberPattern = /\d+/g 
    let numbers = value.match(numberPattern)

    if (numbers === null) {
        return 0
    }  

    return parseInt(numbers.join([]))
}
// 675805714

getDrawable() is deprecated, so try this

imageView.setImageResource(R.drawable.fileName)

A neat trick for fast rounding is to add .5 before you cast your decimal to an int.

decimal d = 10.1m;
d += .5m;
int i = (int)d;

Still leaves i=10, but

decimal d = 10.5m;
d += .5m;
int i = (int)d;

Would round up so that i=11.

I had a similar problem recently, and needed to change the permissions of my vendor folder

By running following commands :

1. php artisan cache:clear
2. chmod -R 777 storage vendor
3. composer dump-autoload

I need to give all the permissions required to open and write vendor files to solve this issue

You have to open chrome using the following flag Go to run menu and type "chrome --disable-web-security --user-data-dir"

Make sure all the instances of chrome are closed before you use the flag to open chrome. You will get a security warning that indicates CORS is enabled.

do this

sudo apt-get install php-curl

and restart server

sudo service apache2 restart

a.button a:hover means "a link that's being hovered over that is a child of a link with the class button".

Go instead for a.button:hover.

You should put this line in your application context:

<context:component-scan base-package="com.cinebot.service" />

Read more about Automatically detecting classes and registering bean definitions in documentation.

Just to extend the answer above you can also index your columns rather than specifying the column names which can also be useful depending on what you're doing. Given that your location is the first field it would look like this:

    bar <- foo[foo[ ,1] == "there", ]

This is useful because you can perform operations on your column value, like looping over specific columns (and you can do the same by indexing row numbers too).

This is also useful if you need to perform some operation on more than one column because you can then specify a range of columns:

    foo[foo[ ,c(1:N)], ]

Or specific columns, as you would expect.

    foo[foo[ ,c(1,5,9)], ]

Array's has

array.length

whereas List has

list.size()

Replace array.size() to array.length

Another option would be to set a flag variable as a Boolean and then change that value based on your criteria.

Dim count as Integer 
Dim flag as Boolean

flag = True

While flag
    count = count + 1 

    If count = 10 Then
        'Set the flag to false         '
        flag = false
    End If

I know, I am late but here is the correct way of doing it. using base64. This technique will convert the array to string.

import base64
import numpy as np
random_array = np.random.randn(32,32)
string_repr = base64.binascii.b2a_base64(random_array).decode("ascii")
array = np.frombuffer(base64.binascii.a2b_base64(string_repr.encode("ascii"))) 

For array to string

Convert binary data to a line of ASCII characters in base64 coding and decode to ASCII to get string repr.

For string to array

First, encode the string in ASCII format then Convert a block of base64 data back to binary and return the binary data.

Useful variation for docker-compose users:

docker-compose ps -q | xargs docker container inspect  \
   -f '{{ range .Mounts }}{{ .Name }}:{{ .Destination }} {{ end }}' 

This will very neatly output parseable volume info. Example from my wordpress docker-compose:

ubuntu@core $ docker-compose ps -q | xargs docker container inspect  -f '{{ range .Mounts }}{{ .Name }}:{{ .Destination }} {{ end }}' 
core_wpdb:/var/lib/mysql 
core_wpcode:/code core_wphtml:/var/www/html 

The output contains one line for each container, listing the volumes (and mount points) used. Alter the {{ .Name }}:{{ .Destination }} portion to output the info you would like.

If you just want a simple list of volumes, one per line

$ docker-compose ps -q | xargs docker container inspect  \
   -f '{{ range .Mounts }}{{ .Name }} {{ end }}' \
   | xargs -n 1 echo
core_wpdb
core_wpcode
core_wphtml

Great to generate a list of volumes to backup. I use this technique along with Blacklabelops Volumerize to backup all volumes used by all containers within a docker-compose. The docs for Volumerize don't call it out, but you don't need to use it in a persistent container or to use the built-in facilities for starting and stopping services. I prefer to leave critical operations such as backup and service control to the actual user (outside docker). My backups are triggered by the actual (non-docker) user account, and use docker-compose stop to stop services, backup all volumes in use, and finally docker-compose start to restart.

Role attribute mainly improve accessibility for people using screen readers. For several cases we use it such as accessibility, device adaptation,server-side processing, and complex data description. Know more click: https://www.w3.org/WAI/PF/HTML/wiki/RoleAttribute.

Every SQL batch has to fit in the Batch Size Limit: 65,536 * Network Packet Size.

Other than that, your query is limited by runtime conditions. It will usually run out of stack size because x IN (a,b,c) is nothing but x=a OR x=b OR x=c which creates an expression tree similar to x=a OR (x=b OR (x=c)), so it gets very deep with a large number of OR. SQL 7 would hit a SO at about 10k values in the IN, but nowdays stacks are much deeper (because of x64), so it can go pretty deep.

Update

You already found Erland's article on the topic of passing lists/arrays to SQL Server. With SQL 2008 you also have Table Valued Parameters which allow you to pass an entire DataTable as a single table type parameter and join on it.

XML and XPath is another viable solution:

SELECT ...
FROM Table
JOIN (
   SELECT x.value(N'.',N'uniqueidentifier') as guid
   FROM @values.nodes(N'/guids/guid') t(x)) as guids
 ON Table.guid = guids.guid;

What I did to achieve the goal was to make this..

# I added an extra_command argument that defaults to blank
def save(self, extra_command="", *args, **kwargs):

and below the save() method is this..

# override the save method to create an image thumbnail
if self.image and extra_command != "skip creating photo thumbnail":
    # your logic here

so when i edit some fields but not editing the image, I put this..

Model.save("skip creating photo thumbnail")

you can replace the "skip creating photo thumbnail" with "im just editing the description" or a more formal text.

Hope this one helps!

in case u wanna do the validation for "some elements" (not all element) on your form.You can use this method:

$('input[name="element-one"], input[name="element-two"], input[name="element-three"]').valid();

Hope it help everybody :)

EDITED

I think that you could use a POST or PATCH method to handle this since they typically design for this.

• Using a POST method is typically used to add an element when used on list resource but you can also support several actions for this method. See this answer: How to Update a REST Resource Collection. You can also support different representation formats for the input (if they correspond to an array or a single elements).

  In the case, it's not necessary to define your format to describe the update.

• Using a PATCH method is also suitable since corresponding requests correspond to a partial update. According to RFC5789 (http://tools.ietf.org/html/rfc5789):

  Several applications extending the Hypertext Transfer Protocol (HTTP) require a feature to do partial resource modification. The existing HTTP PUT method only allows a complete replacement of a document. This proposal adds a new HTTP method, PATCH, to modify an existing HTTP resource.

  In the case, you have to define your format to describe the partial update.

I think that in this case, POST and PATCH are quite similar since you don't really need to describe the operation to do for each element. I would say that it depends on the format of the representation to send.

The case of PUT is a bit less clear. In fact, when using a method PUT, you should provide the whole list. As a matter of fact, the provided representation in the request will be in replacement of the list resource one.

You can have two options regarding the resource paths.

• Using the resource path for doc list

In this case, you need to explicitely provide the link of docs with a binder in the representation you provide in the request.

Here is a sample route for this /docs.

The content of such approach could be for method POST:

[
    { "doc_number": 1, "binder": 4, (other fields in the case of creation) },
    { "doc_number": 2, "binder": 4, (other fields in the case of creation) },
    { "doc_number": 3, "binder": 5, (other fields in the case of creation) },
    (...)
]

• Using sub resource path of binder element

In addition you could also consider to leverage sub routes to describe the link between docs and binders. The hints regarding the association between a doc and a binder doesn't have now to be specified within the request content.

Here is a sample route for this /binder/{binderId}/docs. In this case, sending a list of docs with a method POST or PATCH will attach docs to the binder with identifier binderId after having created the doc if it doesn't exist.

The content of such approach could be for method POST:

[
    { "doc_number": 1, (other fields in the case of creation) },
    { "doc_number": 2, (other fields in the case of creation) },
    { "doc_number": 3, (other fields in the case of creation) },
    (...)
]

Regarding the response, it's up to you to define the level of response and the errors to return. I see two levels: the status level (global level) and the payload level (thinner level). It's also up to you to define if all the inserts / updates corresponding to your request must be atomic or not.

• Atomic

In this case, you can leverage the HTTP status. If everything goes well, you get a status 200. If not, another status like 400 if the provided data aren't correct (for example binder id not valid) or something else.

• Non atomic

In this case, a status 200 will be returned and it's up to the response representation to describe what was done and where errors eventually occur. ElasticSearch has an endpoint in its REST API for bulk update. This could give you some ideas at this level: http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/bulk.html.

• Asynchronous

You can also implement an asynchronous processing to handle the provided data. In this case, the HTTP status returns will be 202. The client needs to pull an additional resource to see what happens.

Before finishing, I also would want to notice that the OData specification addresses the issue regarding relations between entities with the feature named navigation links. Perhaps could you have a look at this ;-)

Using font-face requires a little understanding of browser inconsistencies and may require some changes on the web server itself. First thing you have to do is check the console to see if/what messages are being generated. Is it a permissions issue or resource not found....?

Secondly because each browser is expecting a different font type I would use Font Squirrel to upload your font and then generate the additional files and CSS needed. http://www.fontsquirrel.com/fontface/generator

And finally, versions of FireFox and IE will not allow fonts to be loaded cross domain. You may need to modify your Apache config or .htaccess (Header set Access-Control-Allow-Origin "*")

To get the rest of the string after the second instance of the space delimiter:

SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(MsgRest, ' ', 1), ' ', -1) AS EMailID
,  SUBSTRING_INDEX(SUBSTRING_INDEX(MsgRest, ' ', 2), ' ', -1) AS DOB
,  IF(
    LOCATE(' ', `MsgRest`) > 0,
    TRIM(SUBSTRING(SUBSTRING(`MsgRest`, LOCATE(' ', `MsgRest`) +1), 
         LOCATE(' ', SUBSTRING(`MsgRest`, LOCATE(' ', `MsgRest`) +1)) +1)),
    NULL
) AS Person
FROM inbox

this.dataGridView1.Columns["CustomerName"].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight; 

Since you actually want a different array which is arr where arr < 255, and 255 otherwise, this can be done simply:

result = np.minimum(arr, 255)

More generally, for a lower and/or upper bound:

result = np.clip(arr, 0, 255)

If you just want to access the values over 255, or something more complicated, @mtitan8's answer is more general, but np.clip and np.minimum (or np.maximum) are nicer and much faster for your case:

In [292]: timeit np.minimum(a, 255)
100000 loops, best of 3: 19.6 µs per loop

In [293]: %%timeit
   .....: c = np.copy(a)
   .....: c[a>255] = 255
   .....: 
10000 loops, best of 3: 86.6 µs per loop

If you want to do it in-place (i.e., modify arr instead of creating result) you can use the out parameter of np.minimum:

np.minimum(arr, 255, out=arr)

or

np.clip(arr, 0, 255, arr)

(the out= name is optional since the arguments in the same order as the function's definition.)

For in-place modification, the boolean indexing speeds up a lot (without having to make and then modify the copy separately), but is still not as fast as minimum:

In [328]: %%timeit
   .....: a = np.random.randint(0, 300, (100,100))
   .....: np.minimum(a, 255, a)
   .....: 
100000 loops, best of 3: 303 µs per loop

In [329]: %%timeit
   .....: a = np.random.randint(0, 300, (100,100))
   .....: a[a>255] = 255
   .....: 
100000 loops, best of 3: 356 µs per loop

For comparison, if you wanted to restrict your values with a minimum as well as a maximum, without clip you would have to do this twice, with something like

np.minimum(a, 255, a)
np.maximum(a, 0, a)

or,

a[a>255] = 255
a[a<0] = 0

Set below code in RouteConfig.cs in App_Start folder

public static void RegisterRoutes(RouteCollection routes)
{
 routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
 routes.MapRoute(
 name: "Default",
 url: "{controller}/{action}/{id}",
 defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional });
}

IF still not working then do below steps

Second Way : You simple follow below steps,

1) Right click on your Project

2) Select Properties

3) Select Web option and then Select Specific Page (Controller/View) and then set your login page

Here, Account is my controller and Login is my action method (saved in Account Controller)

Basically, pip comes with python itself.Therefore it carries no meaning for using pip itself to install or upgrade python. Thus,try to install python through installer itself,visit the site "https://www.python.org/downloads/" for more help. Thank you.

You can use array.slice(0,1) // First index is removed and array is returned.

Try redirecting the output to Out-Null. Like so,

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose | out-null

No, == between Integer, Long etc will check for reference equality - i.e.

Integer x = ...;
Integer y = ...;

System.out.println(x == y);

this will check whether x and y refer to the same object rather than equal objects.

So

Integer x = new Integer(10);
Integer y = new Integer(10);

System.out.println(x == y);

is guaranteed to print false. Interning of "small" autoboxed values can lead to tricky results:

Integer x = 10;
Integer y = 10;

System.out.println(x == y);

This will print true, due to the rules of boxing (JLS section 5.1.7). It's still reference equality being used, but the references genuinely are equal.

If the value p being boxed is an integer literal of type int between -128 and 127 inclusive (§3.10.1), or the boolean literal true or false (§3.10.3), or a character literal between '\u0000' and '\u007f' inclusive (§3.10.4), then let a and b be the results of any two boxing conversions of p. It is always the case that a == b.

Personally I'd use:

if (x.intValue() == y.intValue())

or

if (x.equals(y))

As you say, for any comparison between a wrapper type (Integer, Long etc) and a numeric type (int, long etc) the wrapper type value is unboxed and the test is applied to the primitive values involved.

This occurs as part of binary numeric promotion (JLS section 5.6.2). Look at each individual operator's documentation to see whether it's applied. For example, from the docs for == and != (JLS 15.21.1):

If the operands of an equality operator are both of numeric type, or one is of numeric type and the other is convertible (§5.1.8) to numeric type, binary numeric promotion is performed on the operands (§5.6.2).

and for <, <=, > and >= (JLS 15.20.1)

The type of each of the operands of a numerical comparison operator must be a type that is convertible (§5.1.8) to a primitive numeric type, or a compile-time error occurs. Binary numeric promotion is performed on the operands (§5.6.2). If the promoted type of the operands is int or long, then signed integer comparison is performed; if this promoted type is float or double, then floating-point comparison is performed.

Note how none of this is considered as part of the situation where neither type is a numeric type.

Yo can use joda time.

private Date dateWitoutTime(Date date){
 return new LocalDate(date).toDate()
}

and you call with:

Date date = new Date();
System.out.println("Without Time = " + dateWitoutTime(date) + "/n  With time = " + date);

On a Windows machine, the .m2 folder is expected to be located under ${user.home}. On Windows 7 and Vista this resolves to <root>\Users\<username> and on XP it is <root>\Documents and Settings\<username>\.m2. So you'd normally see it under c:\Users\Jonathan\.m2.

If you want to create a folder with a . prefix on Windows, you can simply do this on the command line.

• Go to Start->Run
• Type cmd and press Enter
• At the command prompt type md c:\Users\Jonathan\.m2 (or equivalent for your ${user.home} value).

Note that you don't actually need the .m2 location unless you want to create a distinct user settings file, which is optional (see the Settings reference for more details).

If you don't need a separate user settings file and don't really want the local repository under your user home you can simply set the location of your repository to a different folder by modifying the global settings file (located in \conf\settings.xml).

The following snippet would set the local repository to c:\Maven\repository for example:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                  http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository>c:\Maven\repository</localRepository>
  ...

You can store and read string information in a cookie.

If it is a session id coming from the server, the server can generate this cookie. And when another request is sent to the server the cookie will come too. Without having to do anything in the browser.

However if it is javascript that creates the session Id. You can create a cookie with javascript, with a function like:

The read function work from any page or tab of the same domain that has written it, either if the cookie was created from the page in javascript or from the server.

Why not store the function itself? myvar = mypackage.mymodule.myfunction is much cleaner.

if you are using sdkman

you can check it with sdk home java <installed_java_version>

$  sdk home java 8.0.252.j9-adpt
/Users/admin/.sdkman/candidates/java/8.0.252.j9-adpt

you can get your installed java version with

$ sdk list java

It's torture. Instead of including a generic conf file, they make you hit return 9000 times to generate one.

If you append json data to query string, and parse it later in web api side. you can parse complex object. It's useful rather than post json object style. This is my solution.

//javascript file 
var data = { UserID: "10", UserName: "Long", AppInstanceID: "100", ProcessGUID: "BF1CC2EB-D9BD-45FD-BF87-939DD8FF9071" };
var request = JSON.stringify(data);
request = encodeURIComponent(request);

doAjaxGet("/ProductWebApi/api/Workflow/StartProcess?data=", request, function (result) {
    window.console.log(result);
});

//webapi file:
[HttpGet]
public ResponseResult StartProcess()
{
    dynamic queryJson = ParseHttpGetJson(Request.RequestUri.Query);
        int appInstanceID = int.Parse(queryJson.AppInstanceID.Value);
    Guid processGUID = Guid.Parse(queryJson.ProcessGUID.Value);
    int userID = int.Parse(queryJson.UserID.Value);
    string userName = queryJson.UserName.Value;
}

//utility function:
public static dynamic ParseHttpGetJson(string query)
{
    if (!string.IsNullOrEmpty(query))
    {
        try
        {
            var json = query.Substring(7, query.Length - 7); //seperate ?data= characters
            json = System.Web.HttpUtility.UrlDecode(json);
            dynamic queryJson = JsonConvert.DeserializeObject<dynamic>(json);

            return queryJson;
        }
        catch (System.Exception e)
        {
            throw new ApplicationException("can't deserialize object as wrong string content!", e);
        }
    }
    else
    {
        return null;
    }
}

In my case, the simplified solution worked fine. The override method must be in your custom viewpager adapter to override TouchEvent listeners and make'em freeze;

@Override
public boolean onTouchEvent(MotionEvent event) {
    return this.enabled && super.onTouchEvent(event);

}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    return this.enabled && super.onInterceptTouchEvent(event);

}

After spending hours looking for the solution to this problem, I finally struck gold by making the changes mentioned on an Eclipse Forum.

Steps:

Prerequisites: mysysgit is installed with default configuration.

1.Create the file C:/Users/Username/.ssh/config (Replace "Username" with your Windows 7 user name. (e.g. C:/Users/John/.ssh/config)) and put this in it:

Host github.com
HostName github.com
User git
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa

2.Try setting up the remote repository now in Eclipse.

Cheers. It should work perfectly.

Even though this is an old question, this way of doing it would take of many situations and seems to be robust. You need to have PHP 5.3.0 or above.

$EndDateTime = DateTime::createFromFormat('d/m/Y', "16/07/2017");
$EndDateTime->modify('+6 days');
echo $EndDateTime->format('d/m/Y');

You can have any type of format for the date string and this would work.

The difference between http and https is that https requests are sent over an ssl-encrypted connection. The ssl-encrypted connection must be established between the browser and the server before the browser sends the http request.

Https requests are in fact http requests that are sent over an ssl encrypted connection. If the server rejects to establish an ssl encrypted connection then the browser will have no connection to send the request over. The browser and the server will have no way of talking to each other. The browser will not be able to send the url that it wants to access and the server will not be able to respond with a redirect to another url.

So this is not possible. If you want to respond to https links, then you need an ssl certificate.

You can try using command : install.packages('*package_name', dependencies = TRUE)

For example is you have to install 'caret' package in your R machine in linux : install.packages('caret', dependencies = TRUE)

Doing so, all the dependencies for the package will also be downloaded.

File.AppendAllText(path, addtext);  // File Operation 2

string readtext = File.ReadAllText(path); // File Operation 3

Console.WriteLine(readtext);

In every File Operation, The File will be Opened and must be Closed prior Opened. Like wise in the Operation 1 you must Close the File Stream for the Further Operations.

Depending on what you're wanting, you can use…

rake db:create

…to build the database from scratch from config/database.yml, or…

rake db:schema:load

…to build the database from scratch from your schema.rb file.

I figured this out a few months back and blogged about it. The summary is:

If you want to use smtplib to send email to multiple recipients, use email.Message.add_header('To', eachRecipientAsString) to add them, and then when you invoke the sendmail method, use email.Message.get_all('To') send the message to all of them. Ditto for Cc and Bcc recipients.

For api 21+ you can use system image with Google Play as I describe below.

For api 19+ (Android 4.4 Kitkat) you can use system image x86 with Google Api (I was able to use it).

For api 17+ (Android 4.2.2) you can TRY to use system image ARM with Google Api (It didn't work for me).

I was able to install Google Play and Google Services as separate apks to pure system image api 16 and 17, but they don't really work after that (services crush and play not opens). So seems like it is not possible to make them work on pure AVD image because they should be installed with root access. The same for updating Google Services on AVD system image with Google API preinstalled - can't update because of incompatible certificates, can't uninstall even using adb because don't have access.

How to setup AVD system image with Google Play

Now even better solution exist: using AVD image with build-in Google Play Services. It will enable you to use Google Services including Google Play. Also you will be able update it without re-creating AVD image.

Open AVD manager and choose create new device. You should use device definition with play store icon.

Then choose system image for it. You should choose one with Google Play and NOT with Google API.

Then launch new device.

You can update Play Services as shown on screenshot, or manually on device..

As on 2014, I can finally say that LINQ is finally there in java 8.So no need to find an alternative of LINQ anymore.

I created an EventManager class (code at the end). The syntax is the following:

#Create an event with no listeners assigned to it
EventManager.addEvent( eventName = [] )

#Create an event with listeners assigned to it
EventManager.addEvent( eventName = [fun1, fun2,...] )

#Create any number event with listeners assigned to them
EventManager.addEvent( eventName1 = [e1fun1, e1fun2,...], eventName2 = [e2fun1, e2fun2,...], ... )

#Add or remove listener to an existing event
EventManager.eventName += extra_fun
EventManager.eventName -= removed_fun

#Delete an event
del EventManager.eventName

#Fire the event
EventManager.eventName()

Here is an Example:

def hello(name):
    print "Hello {}".format(name)
    
def greetings(name):
    print "Greetings {}".format(name)

EventManager.addEvent( salute = [greetings] )
EventManager.salute += hello

print "\nInitial salute"
EventManager.salute('Oscar')

print "\nNow remove greetings"
EventManager.salute -= greetings
EventManager.salute('Oscar')

Output:

Initial salute
Greetings Oscar
Hello Oscar

Now remove greetings
Hello Oscar

EventManger Code:

class EventManager:
    
    class Event:
        def __init__(self,functions):
            if type(functions) is not list:
                raise ValueError("functions parameter has to be a list")
            self.functions = functions
            
        def __iadd__(self,func):
            self.functions.append(func)
            return self
            
        def __isub__(self,func):
            self.functions.remove(func)

        """
        addEvent( event1 = [f1,f2,...], event2 = [g1,g2,...], ... )
        creates events using **kvargs to create any number of events. Each event recieves a list of functions,
        where every function in the list recieves the same parameters.
        
        Example:
        
        def hello(): print "Hello ",
        def world(): print "World"
        
        EventManager.addEvent( salute = [hello] )
        EventManager.salute += world
        
        EventManager.salute()
        
        Output:

Tested in Ubuntu 16.04.

The following snippet shows an example, which can archive a throughput of 400 MB/s while reading and hashing the file.

It is using a library called hash-wasm, which is based on WebAssembly and calculates the hash faster than js-only libraries. As of 2020, all modern browsers support WebAssembly.

const chunkSize = 64 * 1024 * 1024;
const fileReader = new FileReader();
let hasher = null;

function hashChunk(chunk) {
  return new Promise((resolve, reject) => {
    fileReader.onload = async(e) => {
      const view = new Uint8Array(e.target.result);
      hasher.update(view);
      resolve();
    };

    fileReader.readAsArrayBuffer(chunk);
  });
}

const readFile = async(file) => {
  if (hasher) {
    hasher.init();
  } else {
    hasher = await hashwasm.createMD5();
  }

  const chunkNumber = Math.floor(file.size / chunkSize);

  for (let i = 0; i <= chunkNumber; i++) {
    const chunk = file.slice(
      chunkSize * i,
      Math.min(chunkSize * (i + 1), file.size)
    );
    await hashChunk(chunk);
  }

  const hash = hasher.digest();
  return Promise.resolve(hash);
};

const fileSelector = document.getElementById("file-input");
const resultElement = document.getElementById("result");

fileSelector.addEventListener("change", async(event) => {
  const file = event.target.files[0];

  resultElement.innerHTML = "Loading...";
  const start = Date.now();
  const hash = await readFile(file);
  const end = Date.now();
  const duration = end - start;
  const fileSizeMB = file.size / 1024 / 1024;
  const throughput = fileSizeMB / (duration / 1000);
  resultElement.innerHTML = `
    Hash: ${hash}<br>
    Duration: ${duration} ms<br>
    Throughput: ${throughput.toFixed(2)} MB/s
  `;
});

<script src="https://cdn.jsdelivr.net/npm/hash-wasm"></script>
<!-- defines the global `hashwasm` variable -->

<input type="file" id="file-input">
<div id="result"></div>

You could also organise them into modules. So it would be something like.

./
controllers
    index.js
    indexController.js
app.js

and then in the indexController.js of the controllers export your controllers.

//indexController.js
module.exports = function(){
//do some set up

var self = {
     indexAction : function (req,res){
       //do your thing
}
return self;
};

then in index.js of controllers dir

exports.indexController = require("./indexController");

and finally in app.js

var controllers = require("./controllers");

app.get("/",controllers.indexController().indexAction);

I think this approach allows for clearer seperation and also you can configure your controllers by passing perhaps a db connection in.

Starting from Spring Boot version 1.2.0.RELEASE , there is a property you can add to your application.properties to set a default date format to all of your classes spring.jackson.date-format.

For your date format example, you would add this line to your properties file:

spring.jackson.date-format=yyyy-MM-dd

Reference https://docs.spring.io/spring-boot/docs/1.2.0.RELEASE/reference/html/common-application-properties.html

x and y returns true if both x and y are true.
x or y returns if either one is true.

From this we can conclude that or contains and within itself unless you mean xOR (or except if and is true)

As of pandas 0.17.0, DataFrame.sort() is deprecated, and set to be removed in a future version of pandas. The way to sort a dataframe by its values is now is DataFrame.sort_values

As such, the answer to your question would now be

df.sort_values(['b', 'c'], ascending=[True, False], inplace=True)

From https://developer.mozilla.org/en-US/docs/Web/CSS/background-color

To set background color:

/* Hexadecimal value with color and 100% transparency*/
background-color: #11ffee00;  /* Fully transparent */

/* Special keyword values */
background-color: transparent;

/* HSL value with color and 100% transparency*/
background-color: hsla(50, 33%, 25%, 1.00);  /* 100% transparent */

/* RGB value with color and 100% transparency*/
background-color: rgba(117, 190, 218, 1.0);  /* 100% transparent */

Change the checkboxes so that the name includes the index inside the brackets:

<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>"> 

The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.

You can set your hash directly to URL too.

window.location.hash = "YourHash";

The result : http://url#YourHash

This isn't a direct answer to the question, but I had the same problem. I installed VSFTPD on my Ubuntu Server VPS. I could upload files, but every file I uploaded didn't have execution permissions (all files had rights "600"). These posts explain explain exactly what you have to do to configure your VSFTPD to set default rights on your files:

• Default File Permissions Apache /var/www/
• vsFTPd default uploaded file permissions on Ubuntu not working

I can also confirm this error.

Workaround: is to use external maven inside m2eclipse, instead of it's embedded maven.

That is done in three steps:

1 Install maven on local machine (the test-machine was Ubuntu 10.10)

mvn --version

Apache Maven 2.2.1 (rdebian-4) Java version: 1.6.0_20 Java home: /usr/lib/jvm/java-6-openjdk/jre Default locale: de_DE, platform encoding: UTF-8 OS name: "linux" version: "2.6.35-32-generic" arch: "amd64" Family: "unix"

2 Run maven externally link how to run maven from console

> cd path-to-pom.xml
> mvn test

3 inside m2eclipse: switch from embedded maven to local maven

• find out where local maven home installation dir is (mvn --version, or google for your MAVEN_HOME, for me this helped me that is /usr/share/maven2 )
• in eclipse Menu->Window->Preferences->Maven->Installation-> enter that string. Then you should have switched to your new external maven.
• then run your Project as e.g. "maven test".

The error-message should be gone.

Check your [sdk directory]/platform-tools directory and if it does not exist, then open the SDK manager in the Android Studio (a button somewhere in the top menu, android logo with a down arrow), switch to SDK tools tab and and select/install the Android SDK Platform-tools.

Alternatively, you can try the standalone SDK Manager: Open the SDK manager and you should see a "Launch Standalone SDK manager" link somewhere at the bottom of the settings window. Click and open the standalone SDK manager, then install/update the

"Tools > Android SDK platform tools". If the above does not solve the problem, try reinstalling the tools: open the "Standalone SDK manager" and uninstall the Android SDK platform-tools, delete the [your sdk directory]/platform-tools directory completely and install it again using the SDK manager.

Hope this helps!

AFAIK, the only way this could be done is by using the state=directory option. While template module supports most of copy options, which in turn supports most file options, you can not use something like state=directory with it. Moreover, it would be quite confusing (would it mean that {{project_root}}/conf/code.conf is a directory ? or would it mean that {{project_root}}/conf/ should be created first.

So I don't think this is possible right now without adding a previous file task.

- file: 
    path: "{{project_root}}/conf"
    state: directory
    recurse: yes

got into same kind of problem, wasn't able to exclude main spring boot class during testing. Solved it using following approach.

Instead of using @SpringBootApplication, use all three annotations which it contains and assign the name to @Configuration

@Configuration("myApp")
@EnableAutoConfiguration
@ComponentScan
public class MyApp { .. }

In your test class define configuration with exactly same name:

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
// ugly hack how to exclude main configuration
@Configuration("myApp")
@SpringApplicationConfiguration(classes = MyTest.class)
public class MyTest { ... }

This should help. Would be nice to have some better way in place how to disable auto scanning for configuration annotations...

I have tried all of the listed questions, but all of them not work for my task: using specific yaml file for some unit test. In my case, it works like this:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(initializers = {ConfigFileApplicationContextInitializer.class})
@TestPropertySource(properties = {"spring.config.location=file:../path/to/specific/config/application.yml"})
public class SomeTest {


    @Value("${my.property.value:#{null}}")
    private String value;

    @Test
    public void test() {
        System.out.println("value = " + value);
    }

}

@bdiamante's answer may only partially help you. If you still get a message after you've suppressed warnings, it's because the pandas library itself is printing the message. There's not much you can do about it unless you edit the Pandas source code yourself. Maybe there's an option internally to suppress them, or a way to override things, but I couldn't find one.

For those who need to know why...

Suppose that you want to ensure a clean working environment. At the top of your script, you put pd.reset_option('all'). With Pandas 0.23.4, you get the following:

>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)

C:\projects\stackoverflow\venv\lib\site-packages\pandas\core\config.py:619: FutureWarning: html.bord
er has been deprecated, use display.html.border instead
(currently both are identical)

  warnings.warn(d.msg, FutureWarning)

: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

C:\projects\stackoverflow\venv\lib\site-packages\pandas\core\config.py:619: FutureWarning:
: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

  warnings.warn(d.msg, FutureWarning)

>>>

Following the @bdiamante's advice, you use the warnings library. Now, true to it's word, the warnings have been removed. However, several pesky messages remain:

>>> import warnings
>>> warnings.simplefilter(action='ignore', category=FutureWarning)
>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)


: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

>>>

In fact, disabling all warnings produces the same output:

>>> import warnings
>>> warnings.simplefilter(action='ignore', category=Warning)
>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)


: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

>>>

In the standard library sense, these aren't true warnings. Pandas implements its own warnings system. Running grep -rn on the warning messages shows that the pandas warning system is implemented in core/config_init.py:

$ grep -rn "html.border has been deprecated"
core/config_init.py:207:html.border has been deprecated, use display.html.border instead

Further chasing shows that I don't have time for this. And you probably don't either. Hopefully this saves you from falling down the rabbit hole or perhaps inspires someone to figure out how to truly suppress these messages!

You enter the

if (!(cin >> input_var))

statement if an error occurs when taking the input from cin. If an error occurs then an error flag is set and future attempts to get input will fail. That's why you need

cin.clear();

to get rid of the error flag. Also, the input which failed will be sitting in what I assume is some sort of buffer. When you try to get input again, it will read the same input in the buffer and it will fail again. That's why you need

cin.ignore(10000,'\n');

It takes out 10000 characters from the buffer but stops if it encounters a newline (\n). The 10000 is just a generic large value.

As already written in answers you need to drop constraints (created automatically by sql) related to all columns that you are trying to delete.

Perform followings steps to do the needful.

1. Get Name of all Constraints using sp_helpconstraint which is a system stored procedure utility - execute following exec sp_helpconstraint '<your table name>'
2. Once you get the name of the constraint then copy that constraint name and execute next statement i.e alter table <your_table_name> drop constraint <constraint_name_that_you_copied_in_1> (It'll be something like this only or similar format)
3. Once you delete the constraint then you can delete 1 or more columns by using conventional method i.e Alter table <YourTableName> Drop column column1, column2 etc

#define can accomplish some jobs that normal C++ cannot, like guarding headers and other tasks. However, it definitely should not be used as a magic number- a static const should be used instead.

As an alternative, you can install 7.1 version of mcrypt and create a symbolic link to it:

Install php7.1-mcrypt:

sudo apt install php7.1-mcrypt

Create a symbolic link:

sudo ln -s /etc/php/7.1/mods-available/mcrypt.ini /etc/php/7.2/mods-available

After enabling mcrypt by sudo phpenmod mcrypt, it gets available.

As already stated there is nothing you can do except restore from a backup. At least now you will have learned to always wrap statements in a transaction to see what happens before you decide to commit. Also, if you don't have a backup of your database this will also teach you to make regular backups of your database.

While we haven't been much help for your imediate problem...hopefully these answers will ensure you don't run into this problem again in the future.

This worked for me.

   /**
     * return date in specific format, given a timestamp.
     *
     * @param  timestamp  $datetime
     * @return string
     */
    public static function showDateString($timestamp)
    {
      if ($timestamp !== NULL) {
        $date = new DateTime();
        $date->setTimestamp(intval($timestamp));
        return $date->format("d-m-Y");
      }
      return '';
    }

i find best solution in https://dzone.com/articles/get-last-record-in-each-mysql-group

select * from `data` where `id` in (select max(`id`) from `data` group by `name_id`)

This is a safer C way than atoi()

const char* str = "123";
int i;

if(sscanf(str, "%d", &i)  == EOF )
{
   /* error */
}

C++ with standard library stringstream: (thanks CMS )

int str2int (const string &str) {
  stringstream ss(str);
  int num;
  if((ss >> num).fail())
  { 
      //ERROR 
  }
  return num;
}

With boost library: (thanks jk)

#include <boost/lexical_cast.hpp>
#include <string>

try
{
    std::string str = "123";
    int number = boost::lexical_cast< int >( str );
}
catch( const boost::bad_lexical_cast & )
{
    // Error
}

Edit: Fixed the stringstream version so that it handles errors. (thanks to CMS's and jk's comment on original post)

Depending on what you're trying to do you could also use curl_multi to achieve it.
