So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

WHERE clause is used to eliminate the tuples in a relation,and HAVING clause is used to eliminate the groups in a relation.

HAVING clause is used for aggregate functions such as MIN,MAX,COUNT,SUM .But always use GROUP BY clause before HAVING clause to minimize the error.

I made this short example which also works.

#include <iostream>
#include <type_traits>

class foo;
class bar;

template<class T>
struct is_bar
{
    template<class Q = T>
    typename std::enable_if<std::is_same<Q, bar>::value, bool>::type check()
    {
        return true;
    }

    template<class Q = T>
    typename std::enable_if<!std::is_same<Q, bar>::value, bool>::type check()
    {
        return false;
    }
};

int main()
{
    is_bar<foo> foo_is_bar;
    is_bar<bar> bar_is_bar;
    if (!foo_is_bar.check() && bar_is_bar.check())
        std::cout << "It works!" << std::endl;

    return 0;
}

Comment if you want me to elaborate. I think the code is more or less self-explanatory, but then again I made it so I might be wrong :)

You can see it in action here.

You don't need to go to 64-bit to see something like this. Consider int32_t on common 32-bit platforms. It might be typedef'ed as int or as a long, but obviously only one of the two at a time. int and long are of course distinct types.

It's not hard to see that there is no workaround which makes int == int32_t == long on 32-bit systems. For the same reason, there's no way to make long == int64_t == long long on 64-bit systems.

If you could, the possible consequences would be rather painful for code that overloaded foo(int), foo(long) and foo(long long) - suddenly they'd have two definitions for the same overload?!

The correct solution is that your template code usually should not be relying on a precise type, but on the properties of that type. The whole same_type logic could still be OK for specific cases:

long foo(long x);
std::tr1::disable_if(same_type(int64_t, long), int64_t)::type foo(int64_t);

I.e., the overload foo(int64_t) is not defined when it's exactly the same as foo(long).

[edit] With C++11, we now have a standard way to write this:

long foo(long x);
std::enable_if<!std::is_same<int64_t, long>::value, int64_t>::type foo(int64_t);

[edit] Or C++20

long foo(long x);
int64_t foo(int64_t) requires (!std::is_same_v<int64_t, long>);

If you want to start with a file you can do this

My problem was having type="application/javascript" on the <script> tag for jQuery. IE8 does not like this! If your webpage is HTML5 you don't even need to declare the type, otherwise go with type="text/javascript" instead.

If you are using electron or other chromium frame, you have to include jquery within window explicitly by:

<script language="javascript" type="text/javascript" src="local_path/jquery.js" onload="window.$ = window.jQuery = module.exports;"></script>

For Swift 4, add as a Delegate to your class:

public protocol TimingDelegate: class {
    var _TICK: Date?{ get set }
}

extension TimingDelegate {
    var TICK: Date {
        _TICK = Date()
        return(_TICK)!
     }

    func TOCK(message: String)  {

        if (_TICK == nil){
            print("Call 'TICK' first!")
        }

        if (message == ""){
            print("\(Date().timeIntervalSince(_TICK!))")
        }
        else{
            print("\(message): \(Date().timeIntervalSince(_TICK!))")
        }
    }
}

Add to our class:

class MyViewcontroller: UIViewController, TimingDelegate

Then add to your class:

var _TICK: Date?

When you want to time something, start with:

TICK

And end with:

TOCK("Timing the XXX routine")

I wanted to provide with a solution inspired by physics.

Imagine a force applied along the line and you are measuring the torque of the force about the point. If the torque is positive (counterclockwise) then the point is to the "left" of the line, but if the torque is negative the point is the "right" of the line.

So if the force vector equals the span of the two points defining the line

fx = x_2 - x_1
fy = y_2 - y_1

you test for the side of a point (px,py) based on the sign of the following test

var torque = fx*(py-y_1)-fy*(px-x_1)
if  torque>0  then
     "point on left side"
else if torque <0 then
     "point on right side"  
else
     "point on line"
end if

I am using this which works if you pass it a date obj or js timestamp:

getHumanReadableDate: function(date) {
    if (date instanceof Date) {
         return date.getDate() + "/" + (date.getMonth() + 1) + "/" + date.getFullYear();
    } else if (isFinite(date)) {//timestamp

I need to click the link who's href has substring "long" in it. How can I do this?

With the beauty of CSS selectors.

your statement would be...

driver.findElement(By.cssSelector("a[href*='long']")).click();

This means, in english,

Find me any 'a' elements, that have the href attribute, and that attribute contains 'long'

You can find a useful article about formulating your own selectors for automation effectively, as well as a list of all the other equality operators. contains, starts with, etc... You can find that at: http://ddavison.io/css/2014/02/18/effective-css-selectors.html

The Activator.CreateInstance method creates an instance of a specified type using the constructor that best matches the specified parameters.

For example, let's say that you have the type name as a string, and you want to use the string to create an instance of that type. You could use Activator.CreateInstance for this:

string objTypeName = "Foo";
Foo foo = (Foo)Activator.CreateInstance(Type.GetType(objTypeName));

Here's an MSDN article that explains it's application in more detail:

http://msdn.microsoft.com/en-us/library/wccyzw83.aspx

The type of the elements of an std::map (which is also the type of an expression obtained by dereferencing an iterator of that map) whose key is K and value is V is std::pair<const K, V> - the key is const to prevent you from interfering with the internal sorting of map values.

std::pair<> has two members named first and second (see here), with quite an intuitive meaning. Thus, given an iterator i to a certain map, the expression:

i->first

Which is equivalent to:

(*i).first

Refers to the first (const) element of the pair object pointed to by the iterator - i.e. it refers to a key in the map. Instead, the expression:

i->second

Which is equivalent to:

(*i).second

Refers to the second element of the pair - i.e. to the corresponding value in the map.

An IDE is an integrated development environment - a suped-up text editor with additional support for developing (such as forms designers, resource editors, etc), compiling and debugging applications. e.g Eclipse, Visual Studio.

A Library is a chunk of code that you can call from your own code, to help you do things more quickly/easily. For example, a Bitmap Processing library will provide facilities for loading and manipulating bitmap images, saving you having to write all that code for yourself. Typically a library will only offer one area of functionality (processing images or operating on zip files)

An API (application programming interface) is a term meaning the functions/methods in a library that you can call to ask it to do things for you - the interface to the library.

An SDK (software development kit) is a library or group of libraries (often with extra tool applications, data files and sample code) that aid you in developing code that uses a particular system (e.g. extension code for using features of an operating system (Windows SDK), drawing 3D graphics via a particular system (DirectX SDK), writing add-ins to extend other applications (Office SDK), or writing code to make a device like an Arduino or a mobile phone do what you want). An SDK will still usually have a single focus.

A toolkit is like an SDK - it's a group of tools (and often code libraries) that you can use to make it easier to access a device or system... Though perhaps with more focus on providing tools and applications than on just code libraries.

A framework is a big library or group of libraries that provides many services (rather than perhaps only one focussed ability as most libraries/SDKs do). For example, .NET provides an application framework - it makes it easier to use most (if not all) of the disparate services you need (e.g. Windows, graphics, printing, communications, etc) to write a vast range of applications - so one "library" provides support for pretty much everything you need to do. Often a framework supplies a complete base on which you build your own code, rather than you building an application that consumes library code to do parts of its work.

There are of course many examples in the wild that won't exactly match these descriptions though.

For full-screen frame redirects and similar things I have two methods. Both work fine on mobile and desktop.

Note this are complete cross-browser working, valid HTML files. Just change title and src for your needs.

1. this is my favorite:

<!DOCTYPE html>
<meta charset=utf-8>
<title> Title-1 </title>
<meta name=viewport content="width=device-width">
<style>
 html, body, iframe { height:100%; width:100%; margin:0; border:0; display:block }
</style>
<iframe src=src1></iframe>

<!-- More verbose CSS for better understanding:
  html   { height:100% }
  body   { height:100%; margin:0 }
  iframe { height:100%; width:100%; border:0; display:block }
-->

or 2. something like that, slightly shorter:

<!DOCTYPE html>
<meta charset=utf-8>
<title> Title-2 </title>
<meta name=viewport content="width=device-width">
<iframe src=src2 style="position:absolute; top:0; left:0; width:100%; height:100%; border:0">
</iframe>

Note:
The above examples avoid using height:100vh because old browsers don't know it (maybe moot these days) and height:100vh is not always equal to height:100% on mobile browsers (probably not applicable here). Otherwise, vh simplifies things a little bit, so

3. this is an example using vh (not my favorite, less compatible with little advantage)

<!DOCTYPE html>
<meta charset=utf-8>
<title> Title-3 </title>
<meta name=viewport content="width=device-width">
<style>
 body { margin:0 }
 iframe { display:block; width:100%; height:100vh; border:0 }
</style>
<iframe src=src3></iframe>

React users, here's an answer for completeness.

React version 16.4.2

You either want to update for every keystroke, or get the value only at submit. Adding the key events to the component works, but there are alternatives as recommended in the official docs.

Controlled vs Uncontrolled components

Controlled

From the Docs - Forms and Controlled components:

In HTML, form elements such as input, textarea, and select typically maintain their own state and update it based on user input. In React, mutable state is typically kept in the state property of components, and only updated with setState().

We can combine the two by making the React state be the “single source of truth”. Then the React component that renders a form also controls what happens in that form on subsequent user input. An input form element whose value is controlled by React in this way is called a “controlled component”.

If you use a controlled component you will have to keep the state updated for every change to the value. For this to happen, you bind an event handler to the component. In the docs' examples, usually the onChange event.

Example:

1) Bind event handler in constructor (value kept in state)

constructor(props) {
    super(props);
    this.state = {value: ''};

    this.handleChange = this.handleChange.bind(this);
}

2) Create handler function

handleChange(event) {
    this.setState({value: event.target.value});
}

3) Create form submit function (value is taken from the state)

handleSubmit(event) {
    alert('A name was submitted: ' + this.state.value);
    event.preventDefault();
}

4) Render

<form onSubmit={this.handleSubmit}>
    <label>
      Name:
      <input type="text" value={this.state.value} onChange={this.handleChange} />
    </label>
    <input type="submit" value="Submit" />
</form>

If you use controlled components, your handleChange function will always be fired, in order to update and keep the proper state. The state will always have the updated value, and when the form is submitted, the value will be taken from the state. This might be a con if your form is very long, because you will have to create a function for every component, or write a simple one that handles every component's change of value.

Uncontrolled

From the Docs - Uncontrolled component

In most cases, we recommend using controlled components to implement forms. In a controlled component, form data is handled by a React component. The alternative is uncontrolled components, where form data is handled by the DOM itself.

To write an uncontrolled component, instead of writing an event handler for every state update, you can use a ref to get form values from the DOM.

The main difference here is that you don't use the onChange function, but rather the onSubmit of the form to get the values, and validate if neccessary.

Example:

1) Bind event handler and create ref to input in constructor (no value kept in state)

constructor(props) {
    super(props);
    this.handleSubmit = this.handleSubmit.bind(this);
    this.input = React.createRef();
}

2) Create form submit function (value is taken from the DOM component)

handleSubmit(event) {
    alert('A name was submitted: ' + this.input.current.value);
    event.preventDefault();
}

3) Render

<form onSubmit={this.handleSubmit}>
    <label>
      Name:
      <input type="text" ref={this.input} />
    </label>
    <input type="submit" value="Submit" />
</form>

If you use uncontrolled components, there is no need to bind a handleChange function. When the form is submitted, the value will be taken from the DOM and the neccessary validations can happen at this point. No need to create any handler functions for any of the input components as well.

Your issue

Now, for your issue:

... I want it to be called when I push 'Enter when the whole number has been entered

If you want to achieve this, use an uncontrolled component. Don't create the onChange handlers if it is not necessary. The enter key will submit the form and the handleSubmit function will be fired.

Changes you need to do:

Remove the onChange call in your element

var inputProcent = React.CreateElement(bootstrap.Input, {type: "text",
    //    bsStyle: this.validationInputFactor(),
    placeholder: this.initialFactor,
    className: "input-block-level",
    // onChange: this.handleInput,
    block: true,
    addonBefore: '%',
    ref:'input',
    hasFeedback: true
});

Handle the form submit and validate your input. You need to get the value from your element in the form submit function and then validate. Make sure you create the reference to your element in the constructor.

  handleSubmit(event) {
      // Get value of input field
      let value = this.input.current.value;
      event.preventDefault();
      // Validate 'value' and submit using your own api or something
  }

Example use of an uncontrolled component:

class NameForm extends React.Component {
  constructor(props) {
    super(props);
    // bind submit function
    this.handleSubmit = this.handleSubmit.bind(this);
    // create reference to input field
    this.input = React.createRef();
  }

  handleSubmit(event) {
    // Get value of input field
    let value = this.input.current.value;
    console.log('value in input field: ' + value );
    event.preventDefault();
    // Validate 'value' and submit using your own api or something
  }

  render() {
    return (
      <form onSubmit={this.handleSubmit}>
        <label>
          Name:
          <input type="text" ref={this.input} />
        </label>
        <input type="submit" value="Submit" />
      </form>
    );
  }
}

ReactDOM.render(
  <NameForm />,
  document.getElementById('root')
);

Both answers are correct. If you user .TO -method then the semicolumn is OK - but not for the addrecipients-method. There you need to split, e.g. :

                Dim Splitter() As String
                Splitter = Split(AddrMail, ";")
                For Each Dest In Splitter
                    .Recipients.Add (Trim(Dest))
                Next

You will have to change the value of

post-max-size
upload-max-filesize

both of which you will find in php.ini

Restarting your server will help it start working. On a local test server running XAMIP, i had to stop the Apache server and restart it. It worked fine after that.

Yes there is. The preferred syntax is to favor str.format over the deprecated % operator.

print "First number is {} and second number is {}".format(first, second)

You may be looking for the ProtectedData class, which encrypts data using the user's logon credentials.

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

Well, note that the request contains binary data, so I'm not posting the request as such - instead, I've converted every non-printable-ascii character into a dot (".").

If you want to only log the stack trace of the error (and not the error message) Node 6 and above automatically includes the error name and message inside the stack trace, which is a bit annoying if you want to do some custom error handling:

console.log(error.stack.replace(error.message, ''))

This workaround will log only the error name and stack trace (so you can, for example, format the error message and display it how you want somewhere else in your code).

The above example would print only the error name follow by the stack trace, for example:

I started using the 'prefix-free' Script available at http://leaverou.github.io/prefixfree so I don't have to take care about the vendor prefixes. It neatly takes care of setting the correct vendor prefix behind the scenes for you. Plus a jQuery Plugin is available as well so one can still use jQuery's .css() method without code changes, so the suggested line in combination with prefix-free would be all you need:

$('.user-text').css('transform', 'scale(' + ui.value + ')');

Actually, the internal behavior is translating the anonymous object to a dictionary. So what I do in these scenarios is go for a dictionary:

@{
  var htmlAttributes = new Dictionary<string, object>
  {
    { "class" , "form-control"},
    { "placeholder", "Why?" }        
  };
  if (Model.IsDisabled)
  {
    htmlAttributes.Add("disabled", "disabled");
  }
}
@Html.EditorFor(m => m.Description, new { htmlAttributes = htmlAttributes })

Or, as Stephen commented here:

@Html.EditorFor(m => m.Description,
    Model.IsDisabled ? (object)new { disabled = "disabled" } : (object)new { })

Apple's advice, in the 10.11 release notes, is:

If you need to percent-encode an entire URL string, you can use this code to encode a NSString intended to be a URL (in urlStringToEncode):

NSString *percentEncodedURLString =
  [[NSURL URLWithDataRepresentation:[urlStringToEncode dataUsingEncoding:NSUTF8StringEncoding] relativeToURL:nil] relativeString];

Building off of @gnovice's answer, you can actually create filled plots with shading only in the area between the two curves. Just use fill in conjunction with fliplr.

Example:

x=0:0.01:2*pi;                  %#initialize x array
y1=sin(x);                      %#create first curve
y2=sin(x)+.5;                   %#create second curve
X=[x,fliplr(x)];                %#create continuous x value array for plotting
Y=[y1,fliplr(y2)];              %#create y values for out and then back
fill(X,Y,'b');                  %#plot filled area

By flipping the x array and concatenating it with the original, you're going out, down, back, and then up to close both arrays in a complete, many-many-many-sided polygon.

Here is how you can pass, multiple commands & arguments in one YAML file with kubernetes:

# Write your commands here
command: ["/bin/sh", "-c"]
# Write your multiple arguments in args
args: ["/usr/local/bin/php /var/www/test.php & /usr/local/bin/php /var/www/vendor/api.php"]

Full containers block from yaml file:

    containers:
      - name: widc-cron # container name
        image: widc-cron # custom docker image
        imagePullPolicy: IfNotPresent # advisable to keep
        # write your command here
        command: ["/bin/sh", "-c"]
        # You can declare multiple arguments here, like this example
        args: ["/usr/local/bin/php /var/www/tools/test.php & /usr/local/bin/php /var/www/vendor/api.php"]
        volumeMounts: # to mount files from config-map generator
          - mountPath: /var/www/session/constants.inc.php
            subPath: constants.inc.php
            name: widc-constants

The answer from Constantin is spot on but for more background this behavior is inherited from Matlab.

The Matlab behavior is explained in the Figure Setup - Displaying Multiple Plots per Figure section of the Matlab documentation.

subplot(m,n,i) breaks the figure window into an m-by-n matrix of small subplots and selects the ithe subplot for the current plot. The plots are numbered along the top row of the figure window, then the second row, and so forth.

Install the Eclipse Metrics Plugin. To create a HTML report (with optional XML and CSV) right-click a project -> Export -> Other -> Metrics.

You can adjust the Lines of Code metrics by ignoring blank and comment-only lines or exclude Javadoc if you want. To do this check the tab at Preferences -> Metrics -> LoC.

That's it. There is no special option to exclude curly braces {}.

The plugin offers an alternative metric to LoC called Number of Statements. This is what the author has to say about it:

This metric represents the number of statements in a method. I consider it a more robust measure than Lines of Code since the latter is fragile with respect to different formatting conventions.

Edit:

After you clarified your question, I understand that you need a view for real-time metrics violations, like compiler warnings or errors. You also need a reporting functionality to create reports for your boss. The plugin I described above is for reporting because you have to export the metrics when you want to see them.

You can use CSS alone to center like so:

Working Example

.center{_x000D_
    position: absolute;_x000D_
    height: 50px;_x000D_
    width: 50px;_x000D_
    background:red;_x000D_
    top:calc(50% - 50px/2); /* height divided by 2*/_x000D_
    left:calc(50% - 50px/2); /* width divided by 2*/_x000D_
}

<div class="center"></div>

calc() allows you to do basic calculations in css.

a regular grammer is never ambiguous because it is either left linear or right linear so we cant make two decision tree for regular grammer so it is always unambiguous.but othert than regular grammar all are may or may not be regular

This is the only thing that worked for me:

document.getElementById("chartContainer").innerHTML = ' ';
document.getElementById("chartContainer").innerHTML = '<canvas id="myCanvas"></canvas>';
var ctx = document.getElementById("myCanvas").getContext("2d");

Try this:

UIBezierPath *shadowPath = [UIBezierPath bezierPathWithRect:view.bounds];
view.layer.masksToBounds = NO;
view.layer.shadowColor = [UIColor blackColor].CGColor;
view.layer.shadowOffset = CGSizeMake(0.0f, 5.0f);
view.layer.shadowOpacity = 0.5f;
view.layer.shadowPath = shadowPath.CGPath;

First of all: The UIBezierPath used as shadowPath is crucial. If you don't use it, you might not notice a difference at first, but the keen eye will observe a certain lag occurring during events like rotating the device and/or similar. It's an important performance tweak.

Regarding your issue specifically: The important line is view.layer.masksToBounds = NO. It disables the clipping of the view's layer's sublayers that extend further than the view's bounds.

For those wondering what the difference between masksToBounds (on the layer) and the view's own clipToBounds property is: There isn't really any. Toggling one will have an effect on the other. Just a different level of abstraction.

Swift 2.2:

override func layoutSubviews()
{
    super.layoutSubviews()

    let shadowPath = UIBezierPath(rect: bounds)
    layer.masksToBounds = false
    layer.shadowColor = UIColor.blackColor().CGColor
    layer.shadowOffset = CGSizeMake(0.0, 5.0)
    layer.shadowOpacity = 0.5
    layer.shadowPath = shadowPath.CGPath
}

Swift 3:

override func layoutSubviews()
{
    super.layoutSubviews()

    let shadowPath = UIBezierPath(rect: bounds)
    layer.masksToBounds = false
    layer.shadowColor = UIColor.black.cgColor
    layer.shadowOffset = CGSize(width: 0.0, height: 5.0)
    layer.shadowOpacity = 0.5
    layer.shadowPath = shadowPath.cgPath
}

The hidden input solution wasn't working for me in Safari. The solution below works, and came from here.

window.onpageshow = function(event) {
if (event.persisted) {
    window.location.reload() 
}
};

You've forgot to define an onclick attribute to do something when the button is clicked, so nothing happening is the correct execution, see below;

<input type="button" id="moreFields" onclick="moreFields()" value="Give me more fields!"  />
                                     ----------------------

With a current version of the Notebook/Jupyter, you can create a Python3 kernel. After starting a new notebook application from the command line with Python 2 you should see an entry „Python 3“ in the dropdown menu „New“. This gives you a notebook that uses Python 3. So you can have two notebooks side-by-side with different Python versions.

The Details

1. Create this directory: mkdir -p ~/.ipython/kernels/python3

2. Create this file ~/.ipython/kernels/python3/kernel.json with this content:

   {
       "display_name": "IPython (Python 3)", 
       "language": "python", 
       "argv": [
           "python3", 
           "-c", "from IPython.kernel.zmq.kernelapp import main; main()", 
           "-f", "{connection_file}"
       ], 
       "codemirror_mode": {
           "version": 2, 
           "name": "ipython"
       }
   }
   

3. Restart the notebook server.

4. Select „Python 3“ from the dropdown menu „New“
5. Work with a Python 3 Notebook
6. Select „Python 2“ from the dropdown menu „New“
7. Work with a Python 2 Notebook

I don't know if it would work, but maybe you could break the page into columns using the multicol package.

\usepackage{multicol}

\begin{document}
\begin{multicols}{2}[Your list here]
\end{multicols}

Just use an <a> by itself, set it to display: block; and set width and height. Get rid of the <span> and <div>. This is the semantic way to do it. There is no need to wrap things in <divs> (or any element) for layout. That is what CSS is for.

Demo: http://jsfiddle.net/ThinkingStiff/89Enq/

HTML:

<a id="music" href="Music.html">Music I Like</a>

CSS:

#music {
    background-color: black;
    color: white;
    display: block;
    height: 40px;
    line-height: 40px;
    text-decoration: none;
    width: 100px;
    text-align: center;
}

Output:

What you probably need to do is redirect the user after the POST / Form Handler script has been ran.

In PHP this is done like so...

<?php
// ... Handle $_POST data, maybe insert it into a database.
// Ok, $_POST data has been handled, redirect the user
header('Location:success.php');
die();
?>

... this should allow you to refresh the page without getting that "Send Data Again" warning.

You can even redirect to the same page (if that's what you're posting to) as the POST variables will not be sent in the headers (and thus not be there to re-POST on refresh)

Basically, you're trying to use int as if it was an Object, which it isn't (well...it's complicated)

id.equals(list[pos].getItemNumber())

Should be...

id == list[pos].getItemNumber()

As other people have commented, because the return type of your method is String Spring won't feel need to do anything with the result.

If you change your signature so that the return type is something that needs marshalling, that should help:

@RequestMapping(value = "/json", method = RequestMethod.GET, produces = "application/json")
@ResponseBody
public Map<String, Object> bar() {
    HashMap<String, Object> map = new HashMap<String, Object>();
    map.put("test", "jsonRestExample");
    return map;
}

This is a different question to mine but there is an answer there that belongs on this question:

svn status | grep '?' | sed 's/^.* /svn add /' | bash

This Problem is because of Path so you need to build the path using following Steps

Goto project ----->Right Click on Project Name ---->properties ---->click on Than Java Build Path option than ---> click Android 4.2.2---->Ok

SSIS (SQL Server Integration Services) is an upgrade of DTS (Data Transformation Services), which is a feature of the previous version of SQL Server. SSIS packages can be created in BIDS (Business Intelligence Development Studio). These can be used to merge data from heterogeneous data sources into SQL Server. They can also be used to populate data warehouses, to clean and standardize data, and to automate administrative tasks.

SQL Server Integration Services (SSIS) is a component of Microsoft SQL Server 2005. It replaces Data Transformation Services, which has been a feature of SQL Server since Version 7.0. Unlike DTS, which was included in all versions, SSIS is only available in the "Standard" and "Enterprise" editions. Integration Services provides a platform to build data integration and workflow applications. The primary use for SSIS is data warehousing as the product features a fast and flexible tool for data extraction, transformation, and loading (ETL).). The tool may also be used to automate maintenance of SQL Server databases, update multidimensional cube data, and perform other functions.

You have to use the jquery's text() function. What it does is:

Get the combined text contents of all matched elements.

The result is a string that contains the combined text contents of all matched elements. This method works on both HTML and XML documents. Cannot be used on input elements. For input field text use the val attribute.

For example:

Find the text in the first paragraph (stripping out the html), then set the html of the last paragraph to show it is just text (the bold is gone).

var str = $("p:first").text();
$("p:last").html(str);

Test Paragraph.

Test Paragraph.

With your markup you have to do:

$('a#a_tbnotesverbergen').text('new text');

and it will result in

<a id="a_tbnotesverbergen" href="#nothing">new text</a>

You may be encouraged to use the Element.getBoundingClientRect() method to get the top offset of your element. This method provides the full offset values (left, top, right, bottom, width, height) of your element in the viewport.

Check the John Resig's post describing how helpful this method is.

To do it without using a JavaScript library such as jQuery, you'd do it like this:

var span = document.getElementById("myspan"),
    text = document.createTextNode(''+intValue);
span.innerHTML = ''; // clear existing
span.appendChild(text);

If you do want to use jQuery, it's just this:

$("#myspan").text(''+intValue);

All this answers will give you the distance in a straight line. If you need to get the distance by road, you have to parse the JSON that Google sends you back after calling his service. You can use this method:

public String getDistance(final double lat1, final double lon1, final double lat2, final double lon2){
    String parsedDistance;
    String response;
        Thread thread=new Thread(new Runnable() {
            @Override
            public void run() {
                try {

                    URL url = new URL("http://maps.googleapis.com/maps/api/directions/json?origin=" + lat1 + "," + lon1 + "&destination=" + lat2 + "," + lon2 + "&sensor=false&units=metric&mode=driving");
                    final HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                    conn.setRequestMethod("POST");
                    InputStream in = new BufferedInputStream(conn.getInputStream());
                    response = org.apache.commons.io.IOUtils.toString(in, "UTF-8");

                    JSONObject jsonObject = new JSONObject(response);
                    JSONArray array = jsonObject.getJSONArray("routes");
                    JSONObject routes = array.getJSONObject(0);
                    JSONArray legs = routes.getJSONArray("legs");
                    JSONObject steps = legs.getJSONObject(0);
                    JSONObject distance = steps.getJSONObject("distance");
                    parsedDistance=distance.getString("text");

                } catch (ProtocolException e) {
                    e.printStackTrace();
                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        });
    thread.start();
    try {
        thread.join();
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    return parsedDistance;
}

lat1 and lon1 are coordinates of origin, lat2 and lon2 are coordinates of destination.

If you want to add wsdl reference in .Net Core project, there is no "Add web reference" option.

To add the wsdl reference go to Solution Explorer, right-click on the References project item and then click on the Add Connected Service option.

Then click 'Microsoft WCF Web Service Reference':

Enter the file path into URI text box and import the WSDL:

It will generate a simple, very basic WCF client and you to use it something like this:

YourServiceClient client = new YourServiceClient();
client.DoSomething();

To install it on a Debian based system simply do

# Install latest JDK
sudo apt install default-jdk

# install unzip if not installed yet
sudo apt install unzip

# get latest sdk tools - link will change. go to https://developer.android.com/studio/#downloads to get the latest one
cd ~
wget https://dl.google.com/android/repository/sdk-tools-linux-4333796.zip

# unpack archive
unzip sdk-tools-linux-4333796.zip

rm sdk-tools-linux-4333796.zip

mkdir android-sdk
mv tools android-sdk/tools

Then add the Android SDK to your PATH, open ~/.bashrc in editor and add the following lines into the file

# Export the Android SDK path 
export ANDROID_HOME=$HOME/android-sdk
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

# Fixes sdkmanager error with java versions higher than java 8
export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

Run

source ~/.bashrc

Show all available sdk packages

sdkmanager --list

Identify latest android platform (here it's 28) and run

sdkmanager "platform-tools" "platforms;android-28"

Now you have adb, fastboot and the latest sdk tools installed

In oracle, generally speaking, there are number of facts that I will mention in following section:

• Each database can have many Schema/User (Logical division).
• Each database can have many tablespaces (Logical division).
• A schema is the set of objects (tables, indexes, views, etc) that belong to a user.
• In Oracle, a user can be considered the same as a schema.
• A database is divided into logical storage units called tablespaces, which group related logical structures together. For example, tablespaces commonly group all of an application’s objects to simplify some administrative operations. You may have a tablespace for application data and an additional one for application indexes.

Therefore, your question, "to see all tablespaces and datafiles belong to SCOTT" is s bit wrong.

However, there are some DBA views encompass information about all database objects, regardless of the owner. Only users with DBA privileges can access these views: DBA_DATA_FILES, DBA_TABLESPACES, DBA_FREE_SPACE, DBA_SEGMENTS.

So, connect to your DB as sysdba and run query through these helpful views. For example this query can help you to find all tablespaces and their data files that objects of your user are located:

SELECT DISTINCT sgm.TABLESPACE_NAME , dtf.FILE_NAME
FROM DBA_SEGMENTS sgm
JOIN DBA_DATA_FILES dtf ON (sgm.TABLESPACE_NAME = dtf.TABLESPACE_NAME)
WHERE sgm.OWNER = 'SCOTT'

You just need to find the right multiplier, which can be easily calculated from the hist object.

myhist <- hist(mtcars$mpg)
multiplier <- myhist$counts / myhist$density
mydensity <- density(mtcars$mpg)
mydensity$y <- mydensity$y * multiplier[1]

plot(myhist)
lines(mydensity)

A more complete version, with a normal density and lines at each standard deviation away from the mean (including the mean):

myhist <- hist(mtcars$mpg)
multiplier <- myhist$counts / myhist$density
mydensity <- density(mtcars$mpg)
mydensity$y <- mydensity$y * multiplier[1]

plot(myhist)
lines(mydensity)

myx <- seq(min(mtcars$mpg), max(mtcars$mpg), length.out= 100)
mymean <- mean(mtcars$mpg)
mysd <- sd(mtcars$mpg)

normal <- dnorm(x = myx, mean = mymean, sd = mysd)
lines(myx, normal * multiplier[1], col = "blue", lwd = 2)

sd_x <- seq(mymean - 3 * mysd, mymean + 3 * mysd, by = mysd)
sd_y <- dnorm(x = sd_x, mean = mymean, sd = mysd) * multiplier[1]

segments(x0 = sd_x, y0= 0, x1 = sd_x, y1 = sd_y, col = "firebrick4", lwd = 2)

In case anyone else looking for additional "enter" keypress support, here's an update to the fiddle provided by Gloppy

Code for keypress binding:

elm.bind("keydown keypress", function(event) {
    if (event.which === 13) {
        scope.$apply(function() {
            ngModelCtrl.$setViewValue(elm.val());
        });
    }
});

I use this to open a workbook and then copy that workbook's data to the template.

Private Sub CommandButton24_Click()
Set Template = ActiveWorkbook
 With Application.FileDialog(msoFileDialogOpen)
    .InitialFileName = "I:\Group - Finance" ' Yu can select any folder you want
    .Filters.Clear
    .Title = "Your Title"
    If Not .Show Then
        MsgBox "No file selected.": Exit Sub
    End If
    Workbooks.OpenText .SelectedItems(1)

'The below is to copy the file into a new sheet in the workbook and paste those values in sheet 1

    Set myfile = ActiveWorkbook
    ActiveWorkbook.Sheets(1).Copy after:=ThisWorkbook.Sheets(1)
    myfile.Close
    Template.Activate
    ActiveSheet.Cells.Select
    Selection.Copy
    Sheets("Sheet1").Select
    Cells.Select
    ActiveSheet.Paste

End With

I had a situation where I needed two 'if' statements that could both go true and an 'else' or default if neither were true, not sure if this is an improvement on Jossef's answer but it seemed cleaner to me:

ng-class="{'class-one' : value.one , 'class-two' : value.two}" class="else-class"

Where value.one and value.two are true, they take precedent over the .else-class

Here is a simple example that I tried to explain.

<div>
    <div *ngIf="product">     <!--If "product" exists-->
      <h2>Product Details</h2><hr>
      <h4>Name: {{ product.name }}</h4>
      <h5>Price: {{ product.price | currency }}</h5>
      <p> Description: {{ product.description }}</p>
    </div>

    <div *ngIf="!product">     <!--If "product" not exists-->
       *Product not found
    </div>
</div>

This merge approach will add one commit on top of master which pastes in whatever is in feature, without complaining about conflicts or other crap.

Before you touch anything

git stash
git status # if anything shows up here, move it to your desktop

Now prepare master

git checkout master
git pull # if there is a problem in this step, it is outside the scope of this answer

Get feature all dressed up

git checkout feature
git merge --strategy=ours master

Go for the kill

git checkout master
git merge --no-ff feature

This answer has been updated to reflect latest stable angularjs version. One important note is that $cookieStore is a thin wrapper surrounding $cookies. They are pretty much the same in that they only work with session cookies. Although, this answers the original question, there are other solutions you may wish to consider such as using localstorage, or jquery.cookie plugin (which would give you more fine-grained control and do serverside cookies. Of course doing so in angularjs means you probably would want to wrap them in a service and use $scope.apply to notify angular of changes to models (in some cases).

One other note and that is that there is a slight difference between the two when pulling data out depending on if you used $cookie to store value or $cookieStore. Of course, you'd really want to use one or the other.

In addition to adding reference to the js file you need to inject ngCookies into your app definition such as:

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

you should then be good to go.

Here is a functional minimal example, where I show that cookieStore is a thin wrapper around cookies:

<!DOCTYPE html>
<html ng-app="myApp">
<head>
   <link rel="stylesheet" type="text/css" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
</head>
<body ng-controller="MyController">

  <h3>Cookies</h3>
  <pre>{{usingCookies|json}}</pre>
  <h3>Cookie Store</h3>
  <pre>{{usingCookieStore|json}}</pre>

  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.19/angular.js"></script>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.19/angular-cookies.js"></script>
  <script>
    angular.module('myApp', ['ngCookies']);
    app.controller('MyController',['$scope','$cookies','$cookieStore', 
                       function($scope,$cookies,$cookieStore) {
      var someSessionObj = { 'innerObj' : 'somesessioncookievalue'};

    $cookies.dotobject = someSessionObj;
    $scope.usingCookies = { 'cookies.dotobject' : $cookies.dotobject, "cookieStore.get" : $cookieStore.get('dotobject') };

    $cookieStore.put('obj', someSessionObj);
    $scope.usingCookieStore = { "cookieStore.get" : $cookieStore.get('obj'), 'cookies.dotobject' : $cookies.obj, };
    }
  </script>

</body>
</html>

The steps are:

1. include angular.js
2. include angular-cookies.js
3. inject ngCookies into your app module (and make sure you reference that module in the ng-app attribute)
4. add a $cookies or $cookieStore parameter to the controller
5. access the cookie as a member variable using the dot (.) operator -- OR --
6. access cookieStore using put/get methods

In the case you are asking about, this represents the HTML DOM element.

So it would be the <a> element that was clicked on.

It works for me on Ubuntu...
cd var/lib/tomcat7
sudo nano logs/catalina.out

Try:

gem install pg -- --with-pg-config=`which pg_config`

Interesting approach could be found here: How To Enlarge Your Columns With No Downtime by spaghettidba

If you try to enlarge this column with a straight “ALTER TABLE” command, you will have to wait for SQLServer to go through all the rows and write the new data type

ALTER TABLE tab_name ALTER COLUMN col_name new_larger_data_type;

To overcome this inconvenience, there is a magic column enlargement pill that your table can take, and it’s called Row Compression. (...) With Row Compression, your fixed size columns can use only the space needed by the smallest data type where the actual data fits.

When table is compressed at ROW level, then ALTER TABLE ALTER COLUMN is metadata only operation.

Different Operators

LIKE and = are different operators. Most answers here focus on the wildcard support, which is not the only difference between these operators!

= is a comparison operator that operates on numbers and strings. When comparing strings, the comparison operator compares whole strings.

LIKE is a string operator that compares character by character.

To complicate matters, both operators use a collation which can have important effects on the result of the comparison.

Motivating Example

Let's first identify an example where these operators produce obviously different results. Allow me to quote from the MySQL manual:

Per the SQL standard, LIKE performs matching on a per-character basis, thus it can produce results different from the = comparison operator:

mysql> SELECT 'ä' LIKE 'ae' COLLATE latin1_german2_ci;
+-----------------------------------------+
| 'ä' LIKE 'ae' COLLATE latin1_german2_ci |
+-----------------------------------------+
|                                       0 |
+-----------------------------------------+
mysql> SELECT 'ä' = 'ae' COLLATE latin1_german2_ci;
+--------------------------------------+
| 'ä' = 'ae' COLLATE latin1_german2_ci |
+--------------------------------------+
|                                    1 |
+--------------------------------------+

Please note that this page of the MySQL manual is called String Comparison Functions, and = is not discussed, which implies that = is not strictly a string comparison function.

How Does = Work?

The SQL Standard § 8.2 describes how = compares strings:

The comparison of two character strings is determined as follows:

a) If the length in characters of X is not equal to the length in characters of Y, then the shorter string is effectively replaced, for the purposes of comparison, with a copy of itself that has been extended to the length of the longer string by concatenation on the right of one or more pad characters, where the pad character is chosen based on CS. If CS has the NO PAD attribute, then the pad character is an implementation-dependent character different from any character in the character set of X and Y that collates less than any string under CS. Otherwise, the pad character is a .

b) The result of the comparison of X and Y is given by the collating sequence CS.

c) Depending on the collating sequence, two strings may compare as equal even if they are of different lengths or contain different sequences of characters. When the operations MAX, MIN, DISTINCT, references to a grouping column, and the UNION, EXCEPT, and INTERSECT operators refer to character strings, the specific value selected by these operations from a set of such equal values is implementation-dependent.

(Emphasis added.)

What does this mean? It means that when comparing strings, the = operator is just a thin wrapper around the current collation. A collation is a library that has various rules for comparing strings. Here's an example of a binary collation from MySQL:

static int my_strnncoll_binary(const CHARSET_INFO *cs __attribute__((unused)),
                               const uchar *s, size_t slen,
                               const uchar *t, size_t tlen,
                               my_bool t_is_prefix)
{
  size_t len= MY_MIN(slen,tlen);
  int cmp= memcmp(s,t,len);
  return cmp ? cmp : (int)((t_is_prefix ? len : slen) - tlen);
}

This particular collation happens to compare byte-by-byte (which is why it's called "binary" — it doesn't give any special meaning to strings). Other collations may provide more advanced comparisons.

For example, here is a UTF-8 collation that supports case-insensitive comparisons. The code is too long to paste here, but go to that link and read the body of my_strnncollsp_utf8mb4(). This collation can process multiple bytes at a time and it can apply various transforms (such as case insensitive comparison). The = operator is completely abstracted from the vagaries of the collation.

How Does LIKE Work?

The SQL Standard § 8.5 describes how LIKE compares strings:

The <predicate>

M LIKE P

is true if there exists a partitioning of M into substrings such that:

i) A substring of M is a sequence of 0 or more contiguous <character representation>s of M and each <character representation> of M is part of exactly one substring.

ii) If the i-th substring specifier of P is an arbitrary character specifier, the i-th substring of M is any single <character representation>.

iii) If the i-th substring specifier of P is an arbitrary string specifier, then the i-th substring of M is any sequence of 0 or more <character representation>s.

iv) If the i-th substring specifier of P is neither an arbitrary character specifier nor an arbitrary string specifier, then the i-th substring of M is equal to that substring specifier according to the collating sequence of the <like predicate>, without the appending of <space> characters to M, and has the same length as that substring specifier.

v) The number of substrings of M is equal to the number of substring specifiers of P.

(Emphasis added.)

This is pretty wordy, so let's break it down. Items ii and iii refer to the wildcards _ and %, respectively. If P does not contain any wildcards, then only item iv applies. This is the case of interest posed by the OP.

In this case, it compares each "substring" (individual characters) in M against each substring in P using the current collation.

Conclusions

The bottom line is that when comparing strings, = compares the entire string while LIKE compares one character at a time. Both comparisons use the current collation. This difference leads to different results in some cases, as evidenced in the first example in this post.

Which one should you use? Nobody can tell you that — you need to use the one that's correct for your use case. Don't prematurely optimize by switching comparison operators.

If you have control over the input file, and it's an array of objects, you can solve this more easily. Arrange to output the file with each record on one line, like this:

[
   {"key": value},
   {"key": value},
   ...

This is still valid JSON.

Then, use the node.js readline module to process them one line at a time.

var fs = require("fs");

var lineReader = require('readline').createInterface({
    input: fs.createReadStream("input.txt")
});

lineReader.on('line', function (line) {
    line = line.trim();

    if (line.charAt(line.length-1) === ',') {
        line = line.substr(0, line.length-1);
    }

    if (line.charAt(0) === '{') {
        processRecord(JSON.parse(line));
    }
});

function processRecord(record) {
    // Process the records one at a time here! 
}

The answer by Nils describes how to convert objects to maps, which I found very useful. However, the OP was also wondering where this information is in the MDN docs. While it may not have been there when the question was originally asked, it is now on the MDN page for Object.entries() under the heading Converting an Object to a Map which states:

Converting an Object to a Map

The new Map() constructor accepts an iterable of entries. With Object.entries, you can easily convert from Object to Map:

const obj = { foo: 'bar', baz: 42 }; 
const map = new Map(Object.entries(obj));
console.log(map); // Map { foo: "bar", baz: 42 }

var rotator = function(){
  widget.Rotator.rotate();
  setTimeout(rotator,5000);
};
rotator();

Or:

setInterval(
  function(){ widget.Rotator.rotate() },
  5000
);

Or:

setInterval(
  widget.Rotator.rotate.bind(widget.Rotator),
  5000
);

Straight out of the documentation for collections.OrderedDict:

>>> # dictionary sorted by value
>>> OrderedDict(sorted(d.items(), key=lambda t: t[1]))
OrderedDict([('pear', 1), ('orange', 2), ('banana', 3), ('apple', 4)])

Adapted to the example in the original post:

>>> l=[2,3,1,4,5]
>>> OrderedDict(sorted(enumerate(l), key=lambda x: x[1])).keys()
[2, 0, 1, 3, 4]

See http://docs.python.org/library/collections.html#collections.OrderedDict for details.

In the rare event that you need to redeploy the SAME STABLE artifact to Nexus, it will fail by default. If you then delete the artifact from Nexus (via the web interface) for the purpose of deploying it again, the deploy will still fail, since just removing the e.g. jar or pom does not clear other files still laying around in the directory. You need to log onto the box and delete the directory in its entirety.

I've found this to work very well. It uses the .range property of the .autofilter object, which seems to be a rather obscure, but very handy, feature:

Sub copyfiltered()
    ' Copies the visible columns
    ' and the selected rows in an autofilter
    '
    ' Assumes that the filter was previously applied
    '
    Dim wsIn As Worksheet
    Dim wsOut As Worksheet

    Set wsIn = Worksheets("Sheet1")
    Set wsOut = Worksheets("Sheet2")

    ' Hide the columns you don't want to copy
    wsIn.Range("B:B,D:D").EntireColumn.Hidden = True

    'Copy the filtered rows from wsIn and and paste in wsOut
    wsIn.AutoFilter.Range.Copy Destination:=wsOut.Range("A1")
End Sub

I find the existing answers a little confusing, because they only indirectly indicate the essential mystifying thing in the code example: both* the "print i" and the "next(a)" are causing their results to be printed.

Since they're printing alternating elements of the original sequence, and it's unexpected that the "next(a)" statement is printing, it appears as if the "print i" statement is printing all the values.

In that light, it becomes more clear that assigning the result of "next(a)" to a variable inhibits the printing of its' result, so that just the alternate values that the "i" loop variable are printed. Similarly, making the "print" statement emit something more distinctive disambiguates it, as well.

(One of the existing answers refutes the others because that answer is having the example code evaluated as a block, so that the interpreter is not reporting the intermediate values for "next(a)".)

The beguiling thing in answering questions, in general, is being explicit about what is obvious once you know the answer. It can be elusive. Likewise critiquing answers once you understand them. It's interesting...

class Belly(models.Model):
    belly_id = models.AutoField(primary_key=True)
    belly_name = models.CharField(max_length=50)

******** or *******

class Belly(models.Model):
   belly_name = models.CharField(max_length=50)

The difference is:

The first table has the primary key belly_id (specified as AutoField) and second table has the primary key id (implicitly).

I think no need to use this directly; a primary key field will automatically be added to your model if you don’t specify. Otherwise Check the Django Documentation for AutoField for further details related to AutoField.

You could always ensure they're in the same case before the comparison:

if ([[stringX uppercaseString] isEqualToString:[stringY uppercaseString]]) {
    // They're equal
}

The main benefit being you avoid the potential issue described by matm regarding comparing nil strings. You could either check the string isn't nil before doing one of the compare:options: methods, or you could be lazy (like me) and ignore the added cost of creating a new string for each comparison (which is minimal if you're only doing one or two comparisons).

Put the following code in your CSS, this works with Bootstrap 4:

.w-100 {
  width: 100% !important;
  height: 75vh;
}

It turns out that the string needed to be turned into a bytearray and to do this I editted the code to

ser.write("%01#RDD0010000107**\r".encode())

This solved the problem

Let's say that you want to display the time elapsed between 5pm on Monday and 2:30pm the next day, Tuesday.

In cell A1 (for example), type in the date. In A2, the time. (If you type in 5 pm, including the space, it will display as 5:00 PM. If you want the day of the week to display as well, then in C3 (for example) enter the formula, =A1, then highlight the cell, go into the formatting dropdown menu, select Custom, and type in dddd.

Repeat all this in the row below.

Finally, say you want to display that duration in cell D2. Enter the formula, =(a2+b2)-(a1+b1). If you want this displayed as "22h 30m", select the cell, and in the formatting menu under Custom, type in h"h" m"m".

For getting SHA1 for a production keystore:

1. Build --> Generate Signed APK...

2. Create keystore with password and follow the steps

3. Go to your Mac/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home/bin and drag the bin folder to the terminal after cd command to point at it so you can use the keytool tool. So, in terminal write cd (drag bin here) then press enter.

4. Then, copy and paste this in the terminal:

   keytool -exportcert -alias Your_keystore_AliasName -keystore /Users/Home/Development/AndroidStudioProjects/YoutubeApp/app/YoutubeApp_keystore.jks -list -v
   

   Erase my path and go where you stored your keystore and drag your keystone and drop it after -keystore in the command line so the path will get created.

   Also, erase Your_keystore_AliaseName to put your alias keystone name that you used when you created it.

5. Press Enter and enter the password :)

6. When you enter the password, the terminal won't show that it receives keyboard entries, but it actually does, so put the password and press Enter even if you don't see the password is typed out.

What error message are you getting?

I'd guess your actual error is because your php variable isn't wrapped in quotes. Try this

$update_query = "UPDATE db.tablename SET insert_time=now() WHERE username='" .$somename . "'"; 

As the message error says, you need to Increase the length of your column to fit the length of the data you are trying to insert (0000-00-00)

EDIT 1:

Following your comment, I run a test table:

mysql> create table testDate(id int(2) not null auto_increment, pdd date default null, primary key(id));
Query OK, 0 rows affected (0.20 sec)

Insertion:

mysql> insert into testDate values(1,'0000-00-00');
Query OK, 1 row affected (0.06 sec)

EDIT 2:

So, aparently you want to insert a NULL value to pdd field as your comment states ? You can do that in 2 ways like this:

Method 1:

mysql> insert into testDate values(2,'');
Query OK, 1 row affected, 1 warning (0.06 sec)

Method 2:

mysql> insert into testDate values(3,NULL);
Query OK, 1 row affected (0.07 sec)

EDIT 3:

You failed to change the default value of pdd field. Here is the syntax how to do it (in my case, I set it to NULL in the start, now I will change it to NOT NULL)

mysql> alter table testDate modify pdd date not null;
Query OK, 3 rows affected, 1 warning (0.60 sec)
Records: 3  Duplicates: 0  Warnings: 1

I was able to resolve the problem by following steps: a. upgrade to the latest chrome version, clear the cache and close the chrome browser b. Download latest Selenium 3.0

The following hack let's you sleep for 5 seconds

ping -n 6 127.0.0.1 > nul

Since ping waits a second between the pings, you have to specify one more than you need.

You can access the index attribute of a df using df.index[i]

>> import pandas as pd
>> import numpy as np
>> df = pd.DataFrame({'a':np.arange(5), 'b':np.random.randn(5)})
   a         b
0  0  1.088998
1  1 -1.381735
2  2  0.035058
3  3 -2.273023
4  4  1.345342

>> df.index[1] ## Second index

>> for i in xrange(len(df)):print df.index[i] ## Using loop

As Tmdean correctly pointed out you can use the Mid() function. The MSDN Library also has a great reference section on VBScript which you can find here:

Let's say we have an external table called employee

hive> SHOW CREATE TABLE employee;
OK
CREATE EXTERNAL TABLE employee(
  id string,
  fname string,
  lname string, 
  salary double)
ROW FORMAT SERDE
  'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
WITH SERDEPROPERTIES (
  'colelction.delim'=':',
  'field.delim'=',',
  'line.delim'='\n',
  'serialization.format'=',')
STORED AS INPUTFORMAT
  'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
  'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'

  'totalSize'='0',
  'transient_lastDdlTime'='1487884795')

1. To create a person table like employee

   CREATE TABLE person LIKE employee;

2. To create a person external table like employee

   CREATE TABLE person LIKE employee LOCATION 'maprfs:/user/hadoop/data/person';

3. then use DESC person; to see the newly created table schema.

Use file_put_contents()

file_put_contents('file.txt', 'bar');
echo file_get_contents('file.txt'); // bar
file_put_contents('file.txt', 'foo');
echo file_get_contents('file.txt'); // foo

Alternatively, if you're stuck with fopen() you can use the w or w+ modes:

'w' Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

'w+' Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

It's not possible to achieve the required level of control over presentation in a regular textarea.

If you're OK with that, try CodeMirror or Ace or Monaco (used in MS VSCode).

From the duplicate thread - an obligatory wikipedia link: Comparison of JavaScript-based source code editors

You can also use the PredicateBuilder from LinqKit to chain multiple typesafe lambda expressions using Or or And.

http://www.albahari.com/nutshell/predicatebuilder.aspx

Newer versions of OpenSSL say BEGIN PRIVATE KEY because they contain the private key + an OID that identifies the key type (this is known as PKCS8 format). To get the old style key (known as either PKCS1 or traditional OpenSSL format) you can do this:

openssl rsa -in server.key -out server_new.key

Alternately, if you have a PKCS1 key and want PKCS8:

openssl pkcs8 -topk8 -nocrypt -in privkey.pem

Coming in PHP 7.1 is the ability to catch multiple types.

So that this:

<?php
try {
    /* ... */
} catch (FirstException $ex) {
    $this->manageException($ex);
} catch (SecondException $ex) {
    $this->manageException($ex);
}
?>

and

<?php
try {

} catch (FirstException | SecondException $ex) {
    $this->manageException($ex);
}
?>

are functionally equivalent.

And if you neither want to use @Autowire nor injecting @Value you can simply do (with fallback included):

System.getProperty("spring.profiles.active", "unknown");

This will return any active profile (or fallback to 'unknown').

var date = new Date().toLocaleDateString("en-US");

Also, you can call method toLocaleDateString with two parameters:

var date = new Date().toLocaleDateString("en-US", {
    "year": "numeric",
    "month": "numeric"
});

Don't Use RubyRacer as it is bad on memory. Installing Node.js as suggested by some people here is a better idea.

This list of available runtimes that can be used by ExecJs Library also documents the use of Node.js

https://github.com/sstephenson/execjs

So, Node.js is not an overkill, and much better solution than using the RubyRacer.

You might want to remove the accents and diacritic signs first, then on each character position check if the "simplified" string is an ascii letter - if it is, the original position shall contain word characters, if not, it can be removed.

From your service method:

function serviceMethod() {
    return $timeout(function() {
        return {
            property: 'value'
        };
    }, 1000);

And in your controller:

serviceName
    .serviceMethod()
    .then(function(data){
        //handle the success condition here
        var x = data.property
    });

It was throwing me this error when I using switch in a function with variables declared in my class:

private void ShowCalendar(final Activity context, Point p, int type) 
{
    switch (type) {
        case type_cat:
            break;

        case type_region:
            break;

        case type_city:
            break;

        default:
            //sth
            break;
    }
}

The problem was solved when I declared final to the variables in the start of the class:

final int type_cat=1, type_region=2, type_city=3;

Vue2: if you only want to detect change on input blur (e.g. after press enter or click somewhere else) do (more info here)

<input @change="foo" v-model... >

If you wanna detect single character changes (during user typing) use

<input @keydown="foo" v-model... >

You can also use @keyup and @input events. If you wanna to pass additional parameters use in template e.g. @keyDown="foo($event, param1, param2)". Comparision below (editable version here)

Ask first yourself: Is your file an internal component of your application? (That usually implies that it's packed inside your JAR, or WAR if it is a web-app; typically, it's some configuration file or static resource, read-only).

If the answer is yes, you don't want to specify an absolute path for the file. But you neither want to access it with a relative path (as your example), because Java assumes that path is relative to the "current directory". Usually the preferred way for this scenario is to load it relatively from the classpath.

Java provides you the classLoader.getResource() method for doing this. And Eclipse (in the normal setup) assumes src/ is to be in the root of your classpath, so that, after compiling, it copies everything to your output directory ( bin/ ), the java files in compiled form ( .class ), the rest as is.

So, for example, if you place your file in src/Files/myfile.txt, it will be copied at compile time to bin/Files/myfile.txt ; and, at runtime, bin/ will be in (the root of) your classpath. So, by calling getResource("/Files/myfile.txt") (in some of its variants) you will be able to read it.

Edited: Further, if your file is conceptually tied to a java class (eg, some com.example.MyClass has a MyClass.cfg associated configuration file), you can use the getResource() method from the class and use a (resource) relative path: MyClass.getResource("MyClass.cfg"). The file then will be searched in the classpath, but with the class package pre-appended. So that, in this scenario, you'll typically place your MyClass.cfg and MyClass.java files in the same directory.

This command will help to pull from the repository as the different user:

git pull https://[email protected]/projectfolder/projectname.git master

It is a workaround, when you are using same machine that someone else used before you, and had saved credentials

Check for any recusive calls for methods. Mainly it is caused when there is recursive call for a method. A simple example is

public static void main(String... args) {
    Main main = new Main();

    main.testMethod(1);
}

public void testMethod(int i) {
    testMethod(i);

    System.out.println(i);
}

Here the System.out.println(i); will be repeatedly pushed to stack when the testMethod is called.

Shelf is a JetBrains feature while Stash is a Git feature for same work. You can switch to different branch without commit and loss of work using either of features. My personal experience is to use Shelf.

I've tried the solution presented in the accepted answer and it did not work for me. I wanted to share what DID work for me as it might help someone else. I've found this solution here.

Basically what you need to do is put your .so files inside a a folder named lib (Note: it is not libs and this is not a mistake). It should be in the same structure it should be in the APK file.

In my case it was:
Project:
|--lib:
|--|--armeabi:
|--|--|--.so files.

So I've made a lib folder and inside it an armeabi folder where I've inserted all the needed .so files. I then zipped the folder into a .zip (the structure inside the zip file is now lib/armeabi/*.so) I renamed the .zip file into armeabi.jar and added the line compile fileTree(dir: 'libs', include: '*.jar') into dependencies {} in the gradle's build file.

This solved my problem in a rather clean way.

git reset --hard

git push origin HEAD --force

If one or more of the commits is tagged, delete the tag(s) first. Otherwise the tagged commit is not removed.

use as below:

<div id="getSessionStorage"></div>

For this to append anything use below code for reference:

$(document).ready(function () {
        var storageVal = sessionStorage.getItem("UserName");
        alert(storageVal);
        $("#getSessionStorage").append(storageVal);
     });

This will appear as below in html (assuming storageVal="Rishabh")

<div id="getSessionStorage">Rishabh</div>

@Bashir almost helped me but I needed:

composer update --no-scripts

I found the answer here: https://laracasts.com/discuss/channels/general-discussion/fatal-error-class-illuminatefoundationapplication-not-found-in-pathtoprojectbootstrapappphp-on-line-14?page=0

Now, 2017, you can do it easier with the new MSTest V2 Framework:

Assert.ThrowsException<Exception>(() => myClass.MyMethodWithError());

//async version
await Assert.ThrowsExceptionAsync<SomeException>(
  () => myObject.SomeMethodAsync()
);

Actually ngAfterViewInit() will initiate only once when the component initiate.

If you really want a event triggers after the HTML element renter on the screen then you can use ngAfterViewChecked()

I had the error when I was trying to make a custom result for a stored procedure and assumed it had to be an entity.

The solution was that I just made a complex type in the Model browser and assigned that as a result to the "Edit function imports".

I will add it here since it looks like this question is where google takes you when you get this error.

I continued to have this problem in ie7 when the browser was at certain widths. Turns out older browsers round the pixel value up if the percentage result isn't a whole number. To solve this you can try setting

overflow: hidden;

on the last element (or all of them).

First click once on your package and then click setting icon on Android Studio.

Close/Unselect Compact Empty Middle Packages

Then, right click your package and rename it.

Thats all.

The file will be stored in a temporary location, so use tmp_name instead of name:

if (move_uploaded_file($_FILES['image']['tmp_name'], __DIR__.'/../../uploads/'. $_FILES["image"]['name'])) {
    echo "Uploaded";
} else {
   echo "File not uploaded";
}

You can specify how to initialize members in the member initializer list:

BigMommaClass {
    BigMommaClass(int, int);

private:
    ThingOne thingOne;
    ThingTwo thingTwo;
};

BigMommaClass::BigMommaClass(int numba1, int numba2)
    : thingOne(numba1 + numba2), thingTwo(numba1, numba2) {}

Greetings if i get you right you need a JavaScript function that doing it

function report(v) {
//To Do
  switch(v) {
    case "daily":
      //Do something
      break;
    case "monthly":
      //Do somthing
      break;
    }
  }

It depends mostly on how much the repository is used. With one user checking in once a day and a branch/merge/etc operation once a week you probably don't need to run it more than once a year.

With several dozen developers working on several dozen projects each checking in 2-3 times a day, you might want to run it nightly.

It won't hurt to run it more frequently than needed, though.

What I'd do is run it now, then a week from now take a measurement of disk utilization, run it again, and measure disk utilization again. If it drops 5% in size, then run it once a week. If it drops more, then run it more frequently. If it drops less, then run it less frequently.

CMake favours passing the full path to link libraries, so assuming libbingitup.a is in ${CMAKE_SOURCE_DIR}, doing the following should succeed:

add_executable(main main.cpp)
target_link_libraries(main ${CMAKE_SOURCE_DIR}/libbingitup.a)

I noticed few things:

Ctrl+/ toggles Folding-enabled or -disabled.

It is Ctrl+* that expands. Ctrl+Shift+* collapses just like Ctrl+Shift+/

If you want to bind to the redis port from your nodejs container you will have to expose that port in the redis container:

version: '2'
services:
  nodejs:
    build:
      context: .
      dockerfile: DockerFile
    ports:
      - "4000:4000"
    links:
      - redis

  redis:
    build:
      context: .
      dockerfile: Dockerfile-redis
    expose:
      - "6379"

The expose tag will let you expose ports without publishing them to the host machine, but they will be exposed to the containers networks.

https://docs.docker.com/compose/compose-file/#expose

The ports tag will be mapping the host port with the container port HOST:CONTAINER

https://docs.docker.com/compose/compose-file/#ports

It is possible of course, use -l: instead of -l. For example -l:libXYZ.a to link with libXYZ.a. Notice the lib written out, as opposed to -lXYZ which would auto expand to libXYZ.

Common approach

There is option for tar program:

-I, --use-compress-program PROG
      filter through PROG (must accept -d)

You can use multithread version of archiver or compressor utility.

Most popular multithread archivers are pigz (instead of gzip) and pbzip2 (instead of bzip2). For instance:

$ tar -I pbzip2 -cf OUTPUT_FILE.tar.bz2 paths_to_archive
$ tar --use-compress-program=pigz -cf OUTPUT_FILE.tar.gz paths_to_archive

Archiver must accept -d. If your replacement utility hasn't this parameter and/or you need specify additional parameters, then use pipes (add parameters if necessary):

$ tar cf - paths_to_archive | pbzip2 > OUTPUT_FILE.tar.gz
$ tar cf - paths_to_archive | pigz > OUTPUT_FILE.tar.gz

Input and output of singlethread and multithread are compatible. You can compress using multithread version and decompress using singlethread version and vice versa.

p7zip

For p7zip for compression you need a small shell script like the following:

#!/bin/sh
case $1 in
  -d) 7za -txz -si -so e;;
   *) 7za -txz -si -so a .;;
esac 2>/dev/null

Save it as 7zhelper.sh. Here the example of usage:

$ tar -I 7zhelper.sh -cf OUTPUT_FILE.tar.7z paths_to_archive
$ tar -I 7zhelper.sh -xf OUTPUT_FILE.tar.7z

xz

Regarding multithreaded XZ support. If you are running version 5.2.0 or above of XZ Utils, you can utilize multiple cores for compression by setting -T or --threads to an appropriate value via the environmental variable XZ_DEFAULTS (e.g. XZ_DEFAULTS="-T 0").

This is a fragment of man for 5.1.0alpha version:

Multithreaded compression and decompression are not implemented yet, so this option has no effect for now.

However this will not work for decompression of files that haven't also been compressed with threading enabled. From man for version 5.2.2:

Threaded decompression hasn't been implemented yet. It will only work on files that contain multiple blocks with size information in block headers. All files compressed in multi-threaded mode meet this condition, but files compressed in single-threaded mode don't even if --block-size=size is used.

Recompiling with replacement

If you build tar from sources, then you can recompile with parameters

--with-gzip=pigz
--with-bzip2=lbzip2
--with-lzip=plzip

After recompiling tar with these options you can check the output of tar's help:

$ tar --help | grep "lbzip2\|plzip\|pigz"
  -j, --bzip2                filter the archive through lbzip2
      --lzip                 filter the archive through plzip
  -z, --gzip, --gunzip, --ungzip   filter the archive through pigz

Heres a simple solution in Swift 5/iOS 13.

extension Date {
    
    func toMilliseconds() -> Int64 {
        Int64(self.timeIntervalSince1970 * 1000)
    }

    init(milliseconds:Int) {
        self = Date().advanced(by: TimeInterval(integerLiteral: Int64(milliseconds / 1000)))
    }
}

This however assumes you have calculated the difference between UTF time and local time and adjusted and accounted for in the milliseconds. For that look to calendar

var cal = Calendar.current
cal.timeZone = TimeZone(abbreviation: "UTC")!
let difference = cal.compare(dateGiven, to: date, toGranularity: .nanosecond)

The [new-ish at the time of writing in 2017] Fetch API is intended to make GET requests easy, but it is able to POST as well.

let data = {element: "barium"};

fetch("/post/data/here", {
  method: "POST", 
  body: JSON.stringify(data)
}).then(res => {
  console.log("Request complete! response:", res);
});

If you are as lazy as me (or just prefer a shortcut/helper):

window.post = function(url, data) {
  return fetch(url, {method: "POST", body: JSON.stringify(data)});
}

// ...

post("post/data/here", {element: "osmium"});

Here is my rather inelegant but working code that deals with the following issues (without any dependencies):

• classList not existing on <svg> elements in IE
• className not representing the class attribute on <svg> elements in IE
• Old IE's broken getAttribute() and setAttribute() implementations

It uses classList where possible.

Code:

var classNameContainsClass = function(fullClassName, className) {
    return !!fullClassName &&
           new RegExp("(?:^|\\s)" + className + "(?:\\s|$)").test(fullClassName);
};

var hasClass = function(el, className) {
    if (el.nodeType !== 1) {
        return false;
    }
    if (typeof el.classList == "object") {
        return (el.nodeType == 1) && el.classList.contains(className);
    } else {
        var classNameSupported = (typeof el.className == "string");
        var elClass = classNameSupported ? el.className : el.getAttribute("class");
        return classNameContainsClass(elClass, className);
    }
};

var addClass = function(el, className) {
    if (el.nodeType !== 1) {
        return;
    }
    if (typeof el.classList == "object") {
        el.classList.add(className);
    } else {
        var classNameSupported = (typeof el.className == "string");
        var elClass = classNameSupported ?
            el.className : el.getAttribute("class");
        if (elClass) {
            if (!classNameContainsClass(elClass, className)) {
                elClass += " " + className;
            }
        } else {
            elClass = className;
        }
        if (classNameSupported) {
            el.className = elClass;
        } else {
            el.setAttribute("class", elClass);
        }
    }
};

var removeClass = (function() {
    function replacer(matched, whiteSpaceBefore, whiteSpaceAfter) {
        return (whiteSpaceBefore && whiteSpaceAfter) ? " " : "";
    }

    return function(el, className) {
        if (el.nodeType !== 1) {
            return;
        }
        if (typeof el.classList == "object") {
            el.classList.remove(className);
        } else {
            var classNameSupported = (typeof el.className == "string");
            var elClass = classNameSupported ?
                el.className : el.getAttribute("class");
            elClass = elClass.replace(new RegExp("(^|\\s)" + className + "(\\s|$)"), replacer);
            if (classNameSupported) {
                el.className = elClass;
            } else {
                el.setAttribute("class", elClass);
            }
        }
    }; //added semicolon here
})();

Example usage:

var el = document.getElementById("someId");
if (hasClass(el, "someClass")) {
    removeClass(el, "someClass");
}
addClass(el, "someOtherClass");

In windows 7, I Got it resolved after adding the environment variables in system level. If you do not have enough permission try to set the %JAVA_HOME% and the %M2_HOME% in System variables instead of User Variables.

The answer that dtsg gave works:

string filePath = ConfigurationManager.AppSettings["ClientsFilePath"];

BUT, you need to add an assembly reference to

System.Configuration

Go to your Solution Explorer and right click on References and select Add reference. Select the Assemblies tab and search for Configuration.

Here is an example of my App.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
  <appSettings>
    <add key="AdminName" value="My Name"/>
    <add key="AdminEMail" value="MyEMailAddress"/>
  </appSettings>
</configuration>

Which you can get in the following way:

string adminName = ConfigurationManager.AppSettings["AdminName"];

When I try:

set guifont=Consolas:h16

I get: Warning: Font "Consolas" reports bad fixed pitch metrics

and the following is work, and don't show the waring.

autocmd vimenter * GuiFont! Consolas:h16

by the way, if you want to use the mouse wheel to control the font-size, then you can add:

function! AdjustFontSize(amount)
    let s:font_size = s:font_size + a:amount
    :execute "GuiFont! Consolas:h" . s:font_size
endfunction

noremap <C-ScrollWheelUp> :call AdjustFontSize(1)<CR>
noremap <C-ScrollWheelDown> :call AdjustFontSize(-1)<CR>

and if you want to pick the font, you can set

set guifont=*

will bring up a font requester, where you can pick the font you want.

Numpy matrices are strictly 2-dimensional, while numpy arrays (ndarrays) are N-dimensional. Matrix objects are a subclass of ndarray, so they inherit all the attributes and methods of ndarrays.

The main advantage of numpy matrices is that they provide a convenient notation for matrix multiplication: if a and b are matrices, then a*b is their matrix product.

import numpy as np

a = np.mat('4 3; 2 1')
b = np.mat('1 2; 3 4')
print(a)
# [[4 3]
#  [2 1]]
print(b)
# [[1 2]
#  [3 4]]
print(a*b)
# [[13 20]
#  [ 5  8]]

On the other hand, as of Python 3.5, NumPy supports infix matrix multiplication using the @ operator, so you can achieve the same convenience of matrix multiplication with ndarrays in Python >= 3.5.

import numpy as np

a = np.array([[4, 3], [2, 1]])
b = np.array([[1, 2], [3, 4]])
print(a@b)
# [[13 20]
#  [ 5  8]]

Both matrix objects and ndarrays have .T to return the transpose, but matrix objects also have .H for the conjugate transpose, and .I for the inverse.

In contrast, numpy arrays consistently abide by the rule that operations are applied element-wise (except for the new @ operator). Thus, if a and b are numpy arrays, then a*b is the array formed by multiplying the components element-wise:

c = np.array([[4, 3], [2, 1]])
d = np.array([[1, 2], [3, 4]])
print(c*d)
# [[4 6]
#  [6 4]]

To obtain the result of matrix multiplication, you use np.dot (or @ in Python >= 3.5, as shown above):

print(np.dot(c,d))
# [[13 20]
#  [ 5  8]]

The ** operator also behaves differently:

print(a**2)
# [[22 15]
#  [10  7]]
print(c**2)
# [[16  9]
#  [ 4  1]]

Since a is a matrix, a**2 returns the matrix product a*a. Since c is an ndarray, c**2 returns an ndarray with each component squared element-wise.

There are other technical differences between matrix objects and ndarrays (having to do with np.ravel, item selection and sequence behavior).

The main advantage of numpy arrays is that they are more general than 2-dimensional matrices. What happens when you want a 3-dimensional array? Then you have to use an ndarray, not a matrix object. Thus, learning to use matrix objects is more work -- you have to learn matrix object operations, and ndarray operations.

Writing a program that mixes both matrices and arrays makes your life difficult because you have to keep track of what type of object your variables are, lest multiplication return something you don't expect.

In contrast, if you stick solely with ndarrays, then you can do everything matrix objects can do, and more, except with slightly different functions/notation.

If you are willing to give up the visual appeal of NumPy matrix product notation (which can be achieved almost as elegantly with ndarrays in Python >= 3.5), then I think NumPy arrays are definitely the way to go.

PS. Of course, you really don't have to choose one at the expense of the other, since np.asmatrix and np.asarray allow you to convert one to the other (as long as the array is 2-dimensional).

There is a synopsis of the differences between NumPy arrays vs NumPy matrixes here.

When it comes to compilation speed, composed interfaces perform better than type intersections:

[...] interfaces create a single flat object type that detects property conflicts. This is in contrast with intersection types, where every constituent is checked before checking against the effective type. Type relationships between interfaces are also cached, as opposed to intersection types.

Thanks to all, for me this solution worked: Magento 404 page in backoffice after login

Accepted solution to this question is, while correct in summing up how to create a custom view engine, does not answer the question correctly. Issue here is that Pino is incorrectly specifying his default route. Particularly his "area" definition is incorrect. "Area" is checked via DataTokens collection and should be added as such:

var defaultRoute = new Route("",new RouteValueDictionary(){{"controller","Default"},{"action","Index"}},null/*constraints*/,new RouteValueDictionary(){{"area","Admin"}},new MvcRouteHandler());
defaultRoute.DataTokens.Add("Namespaces","MyProject.Web.Admin.Controller"); 
routes.Add(defaultRoute);

Specified "area" in defaults object will be ignored. Code above creates a default route, which catches on requests to your site's root and then calls Default controller, Index action in Admin area. Please also note "Namespaces" key being added to DataTokens, this is only required if you have multiple controllers with same name. This solution is verified with Mvc2 and Mvc3 .NET 3.5/4.0

The other solutions seem to stray from the blessed path and I found that my scenario was covered in the Typescript documentation which I've paraphrased below:

interface AppPackageCheck<T> {
  new (packageExists: boolean): T
  checkIfPackageExists(): boolean;
}

class WebApp {
    public static checkIfPackageExists(): boolean {
        return false;
    }

    constructor(public packageExists: boolean) {}
}

class BackendApp {
    constructor(public packageExists: boolean) {}
}

function createApp<T>(type: AppPackageCheck<T>): T {
    const packageExists = type.checkIfPackageExists();
    return new type(packageExists)
}

let web = createApp(WebApp);

// compiler failure here, missing checkIfPackageExists
let backend = createApp(BackendApp); 

Had a similar problem on Centos 7. When I tried to apply the solution prescribed by Sorin, I started moving in cycles. First I had a permission {write} denied. Then when I solved that I had a permission { connectto } denied. Then back again to permission {write } denied.

Following @Sid answer above of checking the flags using getsebool -a | grep httpd and toggling them I found that in addition to the httpd_can_network_connect being off. http_anon_write was also off resulting in permission denied write and permission denied {connectto}

type=AVC msg=audit(1501830505.174:799183): avc:  
denied  { write } for  pid=12144 comm="nginx" name="myroject.sock" 
dev="dm-2" ino=134718735 scontext=system_u:system_r:httpd_t:s0 
tcontext=system_u:object_r:default_t:s0 tclass=sock_file

Obtained using sudo cat /var/log/audit/audit.log | grep nginx | grep denied as explained above.

So I solved them one at a time, toggling the flags on one at a time.

setsebool httpd_can_network_connect on -P

Then running the commands specified by @sorin and @Joseph above

sudo cat /var/log/audit/audit.log | grep nginx | grep denied | 
audit2allow -M mynginx
sudo semodule -i mynginx.pp

Basically you can check the permissions set on setsebool and correlate that with the error obtained from grepp'ing' audit.log nginx, denied

This is for Phonegap 3.0.x to 3.3.x. For PhoneGap 3.4.0 and higher see below.

Found part of the answer here, at Phonegap documentation. The full process is the following:

1. Open a command line window, and go to /path/to/your/project/platforms/android/cordova.

2. Run build --release. This creates an unsigned release APK at /path/to/your/project/platforms/android/bin folder, called YourAppName-release-unsigned.apk.

3. Sign and align the APK using the instructions at android developer official docs.

Thanks to @LaurieClark for the link (http://iphonedevlog.wordpress.com/2013/08/16/using-phonegap-3-0-cli-on-mac-osx-10-to-build-ios-and-android-projects/), and the blogger who post it, because it put me on the track.

I created a small component that handles this for you: react-toggle-display

It sets the style attribute to display: none !important based on the hide or show props.

Example usage:

var ToggleDisplay = require('react-toggle-display');

var Search = React.createClass({
    getInitialState: function() {
        return { showResults: false };
    },
    onClick: function() {
        this.setState({ showResults: true });
    },
    render: function() {
        return (
            <div>
                <input type="submit" value="Search" onClick={this.onClick} />
                <ToggleDisplay show={this.state.showResults}>
                    <Results />
                </ToggleDisplay>
            </div>
        );
    }
});

var Results = React.createClass({
    render: function() {
        return (
            <div id="results" className="search-results">
                Some Results
            </div>
        );
    }
});

React.renderComponent(<Search />, document.body);

To get the definition of the SQL codes, the easiest way is to use db2 cli!

at the unix or dos command prompt, just type

db2 "? SQL302"

this will give you the required explanation of the particular SQL code that you normally see in the java exception or your db2 sql output :)

hope this helped.

use JsonParser; for example:

JsonParser parser = new JsonParser();
JsonObject o = parser.parse("{\"a\": \"A\"}").getAsJsonObject();

Since there is the [vba] tag, split is also easy:

str1 = "001 baseball"
str2 = Split(str1)

Then use str2(1).

If you want to select only one of two nodes with union operator, you can use this solution: (//bookstore/book/title | //bookstore/city/zipcode/title)[1]

On one project where we had 4 environments (development, test, staging and production) we developed a system where the application selected the appropriate configuration based on the machine name it was deployed to.

This worked for us because:

• administrators could deploy applications without involving developers (a requirement) and without having to fiddle with config files (which they hated);
• machine names adhered to a convention. We matched names using a regular expression and deployed to multiple machines in an environment; and
• we used integrated security for connection strings. This means we could keep account names in our config files at design time without revealing any passwords.

It worked well for us in this instance, but probably wouldn't work everywhere.

Here is my updated code. It works fine and it can help you.

    initialValues.put("password", pass);
    initialValues.put("photo",photo);
    initialValues.put("visibility",visibility);
    return db.insert("userdetails", null, initialValues);
}

retrieve the image as follows

Cursor cur=your query;
while(cur.moveToNext())
{
     byte[] photo=cur.getBlob(index of blob cloumn);
}

convert the byte[] into image

ByteArrayInputStream imageStream = new ByteArrayInputStream(photo);
Bitmap theImage= BitmapFactory.decodeStream(imageStream);

I think this content may solve your problem

Combining two inputs, where the group take up all width (100%), and the size is not 50% - 50%, no additional css. I made it nicely by the following code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>_x000D_
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
_x000D_
<div class="container">_x000D_
    <form>_x000D_
        <div class="form-group">_x000D_
            <label>Name</label>_x000D_
            <div class="input-group" style="width:100%">_x000D_
                <span class="input-group-btn" style="width:100px;">_x000D_
     <select class="form-control">_x000D_
                     <option>Mr.</option>_x000D_
                     <option>Mrs.</option>_x000D_
                     <option>Dr</option>_x000D_
                 </select>_x000D_
    </span>_x000D_
    <input class="form-control" id="name" name="name" placeholder="Type your name" type="text">_x000D_
            </div>_x000D_
        </div>_x000D_
    </form>_x000D_
</div>

And if you are looking for case insensitive match, use pattern

Pattern pattern = Pattern.compile("\\bitem1 |item2\\b",java.util.regex.Pattern.CASE_INSENSITIVE);

Matcher matcher = pattern.matcher(input);
if (matcher.find()) { 
    ...
}

With the assumption that there's only one element:

 $("#grid_GridHeader")[0]
 $("#grid_GridHeader").get(0)
 $("#grid_GridHeader").get()

...are all equivalent, returning the single underlying element.

From the jQuery source code, you can see that get(0), under the covers, essentially does the same thing as the [0] approach:

 // Return just the object
 ( num < 0 ? this.slice(num)[ 0 ] : this[ num ] );

Let's illustrate what's happening here:

Python 3.1.2 (r312:79147, Sep 27 2010, 09:45:41) 
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> class Foo:
...     def __init__(self, x=[]):
...         x.append(1)
... 
>>> Foo.__init__.__defaults__
([],)
>>> f = Foo()
>>> Foo.__init__.__defaults__
([1],)
>>> f2 = Foo()
>>> Foo.__init__.__defaults__
([1, 1],)

You can see that the default arguments are stored in a tuple which is an attribute of the function in question. This actually has nothing to do with the class in question and goes for any function. In python 2, the attribute will be func.func_defaults.

As other posters have pointed out, you probably want to use None as a sentinel value and give each instance it's own list.

 Mail::send('emails.activation', $data, function($message){
        $message->from('email@from', 'name');
        $message->to($email)->subject($subject);
    });

I dont know why, but in my case I put the from's information in the function and it's work fine.

A much shorter version for getting a list of all subclasses:

from itertools import chain

def subclasses(cls):
    return list(
        chain.from_iterable(
            [list(chain.from_iterable([[x], subclasses(x)])) for x in cls.__subclasses__()]
        )
    )

Use the ampersand just like you would from the shell.

#!/usr/bin/bash
function_to_fork() {
   ...
}

function_to_fork &
# ... execution continues in parent process ...

select * from (select * from table order by value desc limit 999999999) v group by v.name

int i,largest = 0;
Scanner scan = new Scanner(System.in);
System.out.println("Enter the number of numbers in the list");
i = scan.nextInt();
int arr[] = new int[i];
System.out.println("Enter the list of numbers:");
for(int j=0;j<i;j++){
    arr[j] = scan.nextInt();
}

The above code works well. I have taken the input of the number of elements in the list and initialized the array accordingly.

I figured it out!

With almost 2 hours worth of trial and error, i figured it out.

This WORKS and is what you do to pass variables to remote job:

    def handle = triggerRemoteJob(remoteJenkinsName: 'remoteJenkins', job: 'RemoteJob' paramters: "param1=${env.PARAM1}\nparam2=${env.param2}")

Use \n to separate two parameters, no spaces..

As opposed to parameters: '''someparams'''

we use paramters: "someparams"

the " ... " is what gets us the values of the desired variables. (These are double quotes, not two single quotes)

the ''' ... ''' or ' ... ' will not get us those values. (Three single quotes or just single quotes)

All parameters here are defined in environment{} block at the start of the pipeline and are modified in stages>steps>scripts wherever necessary.

I also tested and found that when you use " ... " you cannot use something like ''' ... "..." ''' or "... '..'..." or any combination of it...

The catch here is that when you are using "..." in parameters section, you cannot pass a string parameter; for example This WILL NOT WORK:

    def handle = triggerRemoteJob(remoteJenkinsName: 'remoteJenkins', job: 'RemoteJob' paramters: "param1=${env.PARAM1}\nparam2='param2'")

if you want to pass something like the one above, you will need to set an environment variable param2='param2' and then use ${env.param2} in the parameters section of remote trigger plugin step

1) bitmap to Drawable :

Drawable mDrawable = new BitmapDrawable(getResources(), bitmap);
// mImageView.setDrawable(mDrawable);

2) drawable to Bitmap :

Bitmap mIcon = BitmapFactory.decodeResource(context.getResources(),R.drawable.icon_resource);
// mImageView.setImageBitmap(mIcon);

Helvetica Neue is a paid font, so you shouldn't @font-face it, as you'd be freely distributing a copyrighted font. It's included in Mac systems but not in windows/linux ones, so yes, plenty of your users wont have it installed. Anyway, you can use 'Arial Narrow' as a windows substitute, which is it's windows equivalent.

The way I would go about this issue is:

If you need to write/replace the file:

echo "some text" | sudo tee /path/to/file

If you need to append to the file:

echo "some text" | sudo tee -a /path/to/file

LIST FILES and FOLDERS in a directory (Full Code):
p.s. you have to uncomment the 5th line if you want only for specific extensions

<?PHP
# The current directory
$directory = dir("./");

# If you want to turn on Extension Filter, then uncomment this:
### $allowed_ext = array(".sample", ".png", ".jpg", ".jpeg", ".txt", ".doc", ".xls");

Putting an encoded json inside the cookie is my favorite method, to get properly formated data out of a cookie. Try that:

$expiry = time() + 12345;
$data = (object) array( "value1" => "just for fun", "value2" => "i'll save whatever I want here" );
$cookieData = (object) array( "data" => $data, "expiry" => $expiry );
setcookie( "cookiename", json_encode( $cookieData ), $expiry );

then when you get your cookie next time:

$cookie = json_decode( $_COOKIE[ "cookiename" ] );

you can simply extract the expiry time, which was inserted as data inside the cookie itself..

$expiry = $cookie->expiry;

and additionally the data which will come out as a usable object :)

$data = $cookie->data;
$value1 = $cookie->data->value1;

etc. I find that to be a much neater way to use cookies, because you can nest as many small objects within other objects as you wish!

Go to htdocs folder, right click, get info, click to unlock the padlock icon, type your password, under sharing permission change the priviledge for everyone to read & write, on the cog wheel button next to the + and - icons, click and select apply to all enclosed items, click to accept security request, close get info. Now xampp can write and read your root folder.

Note:

1. If you copy a new folder into the htdocs after this, you need to repeat the process for that folder to have write permission.

2. When you move your files to the live server, you need to also chmod the appropriate files & folders on the server as well.

To make it work you have to replace a run this line of code serviceMetadata httpGetEnabled="true"/> http instead of https and security mode="None" />

I'm using this lib to access nested dict keys

https://github.com/mewwts/addict

 import requests
 from addict import Dict
 r = requests.get('http://api.zippopotam.us/us/ma/belmont')
 j = Dict(r.json())

 print j.state
 print j.places[1]['post code']  # only work with keys without '-', space, or starting with number 

We don't need to access the canvas context.

Implementing hednek in pure JS you would get canvas.setAttribute('style', 'background-color:#00F8'). But my preferred method requires converting the kabab-case to camelCase.

canvas.style.backgroundColor = '#00F8'

Materialized views are disk based and are updated periodically based upon the query definition.

Views are virtual only and run the query definition each time they are accessed.

Add the following 2 lines

var regex = new Regex(Regex.Escape(","));
sb_trim = regex.Replace(sb_trim, " ", 1);

If sb_trim= John,Smith,100000,M the above code will return "John Smith,100000,M"

-num will equal to num for Integer.MIN_VALUE as

 Integer.MIN_VALUE =  Integer.MIN_VALUE * -1

you can't use aliases from select list inside the WHERE clause (because of the Order of Evaluation of a SELECT statement)

also you cannot use OVER clause inside WHERE clause - "You can specify analytic functions with this clause in the select list or ORDER BY clause." (citation from docs.oracle.com)

select *
from (select
  staff_id, site_id, pay_level, date, 
  max(date) over (partition by staff_id) max_date
  from owner.table
  where end_enrollment_date is null
)
where date = max_date

In order to get it REALLY smoooth...

x <- 1:10
y <- c(2,4,6,8,7,8,14,16,18,20)
lo <- loess(y~x)
plot(x,y)
xl <- seq(min(x),max(x), (max(x) - min(x))/1000)
lines(xl, predict(lo,xl), col='red', lwd=2)

This style interpolates lots of extra points and gets you a curve that is very smooth. It also appears to be the the approach that ggplot takes. If the standard level of smoothness is fine you can just use.

scatter.smooth(x, y)

Here is a simple example to get the selected value of dropdown in javascript

First we design the UI for dropdown

<div class="col-xs-12">
<select class="form-control" id="language">
    <option>---SELECT---</option>
    <option>JAVA</option>
    <option>C</option>
    <option>C++</option>
    <option>PERL</option>
</select>

Next we need to write script to get the selected item

<script type="text/javascript">
$(document).ready(function () {
    $('#language').change(function () {
        var doc = document.getElementById("language");
        alert("You selected " + doc.options[doc.selectedIndex].value);
    });
});

Now When change the dropdown the selected item will be alert.

I've already encountered this error and this is the best solution I've found:

A View in Oracle and in other database systems is simply the representation of a SQL statement that is stored in memory so that it can easily be re-used. For example, if we frequently issue the following query

SELECT customerid, customername FROM customers WHERE countryid='US';

To create a view use the CREATE VIEW command as seen in this example

CREATE VIEW view_uscustomers
AS
SELECT customerid, customername FROM customers WHERE countryid='US';

This command creates a new view called view_uscustomers. Note that this command does not result in anything being actually stored in the database at all except for a data dictionary entry that defines this view. This means that every time you query this view, Oracle has to go out and execute the view and query the database data. We can query the view like this:

SELECT * FROM view_uscustomers WHERE customerid BETWEEN 100 AND 200;

And Oracle will transform the query into this:

SELECT * 
FROM (select customerid, customername from customers WHERE countryid='US') 
WHERE customerid BETWEEN 100 AND 200

Benefits of using Views

• Commonality of code being used. Since a view is based on one common set of SQL, this means that when it is called it’s less likely to require parsing.
• Security. Views have long been used to hide the tables that actually contain the data you are querying. Also, views can be used to restrict the columns that a given user has access to.
• Predicate pushing

You can find advanced topics in this article about "How to Create and Manage Views in Oracle."

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#intern()

Basically doing String.intern() on a series of strings will ensure that all strings having same contents share same memory. So if you have list of names where 'john' appears 1000 times, by interning you ensure only one 'john' is actually allocated memory.

This can be useful to reduce memory requirements of your program. But be aware that the cache is maintained by JVM in permanent memory pool which is usually limited in size compared to heap so you should not use intern if you don't have too many duplicate values.

More on memory constraints of using intern()

On one hand, it is true that you can remove String duplicates by internalizing them. The problem is that the internalized strings go to the Permanent Generation, which is an area of the JVM that is reserved for non-user objects, like Classes, Methods and other internal JVM objects. The size of this area is limited, and is usually much smaller than the heap. Calling intern() on a String has the effect of moving it out from the heap into the permanent generation, and you risk running out of PermGen space.

-- From: http://www.codeinstructions.com/2009/01/busting-javalangstringintern-myths.html

From JDK 7 (I mean in HotSpot), something has changed.

In JDK 7, interned strings are no longer allocated in the permanent generation of the Java heap, but are instead allocated in the main part of the Java heap (known as the young and old generations), along with the other objects created by the application. This change will result in more data residing in the main Java heap, and less data in the permanent generation, and thus may require heap sizes to be adjusted. Most applications will see only relatively small differences in heap usage due to this change, but larger applications that load many classes or make heavy use of the String.intern() method will see more significant differences.

-- From Java SE 7 Features and Enhancements

Update: Interned strings are stored in main heap from Java 7 onwards. http://www.oracle.com/technetwork/java/javase/jdk7-relnotes-418459.html#jdk7changes

Use of finishAffinity() may be an good option if you want to close all Activity of the app. As per the Android Docs-

Finish this activity as well as all activities immediately below it in the current task that have the same affinity.

Using sessionStorage for this is not possible.

From the MDN Docs

Opening a page in a new tab or window will cause a new session to be initiated.

That means that you can't share between tabs, for this you should use localStorage

compare properties in the array if one matches the input then set something to the value of the loops current position, which is also the index of the current looked up item.

simple eg.

dim x,y,z as integer
dim aNames, aIndexes as array
dim sFind as string
for x = 1 to length(aNames)

    if aNames(x) = sFind then y = x

y is then the index of the item in the array, then loop could be used to store these in an array also so instead of the above you would have:

z = 1
for x = 1 to length(aNames)
    if aNames(x) = sFind then 
        aIndexes(z) = x 
        z = z + 1
    endif

I had the same requirements to create a kind of step progress tracker so I created a JavaScript plugin for that purpose. Here is the JsFiddle for the demo for this step progress tracker. You can access its code on GitHub as well.

What it basically does is, it takes the json data(in a particular format described below) as input and creates the progress tracker based on that. Highlighted steps indicates the completed steps.

It's html will somewhat look like shown below with default CSS but you can customize it as per the theme of your application. There is an option to show tool-tip text for each steps as well.

Here is some code snippet for that:

//container div 
<div id="tracker1" style="width: 700px">
</div>

//sample JSON data
var sampleJson1 = {
ToolTipPosition: "bottom",
data: [{ order: 1, Text: "Foo", ToolTipText: "Step1-Foo", highlighted: true },
    { order: 2, Text: "Bar", ToolTipText: "Step2-Bar", highlighted: true },
    { order: 3, Text: "Baz", ToolTipText: "Step3-Baz", highlighted: false },
    { order: 4, Text: "Quux", ToolTipText: "Step4-Quux", highlighted: false }]
};    

//Invoking the plugin
$(document).ready(function () {
        $("#tracker1").progressTracker(sampleJson1);
    });

Hopefully it will be useful for somebody else as well!

const x = JSON.stringify(data);
const y = 'search text';

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

Stopwatch is designed for this purpose and is one of the best ways to measure time execution in .NET.

var watch = System.Diagnostics.Stopwatch.StartNew();
// the code that you want to measure comes here
watch.Stop();
var elapsedMs = watch.ElapsedMilliseconds;

Do not use DateTime to measure time execution in .NET.

UPDATE:

As pointed out by @series0ne in the comments section: If you want a real precise measurement of the execution of some code, you will have to use the performance counters that's built into the operating system. The following answer contains a nice overview.

I think this is the clearest way:

require 'open-uri'

File.write 'image.png', open('http://example.com/image.png').read

Since required quite often it might as well be brief:

=1*(A1="")

This will not return 1 if the cell appears empty but contains say a space or a formula of the kind =IF(B1=3,"Yes","") where B1 does not contain 3.

=A1="" will return either TRUE or FALSE but those in an equation are treated as 1 and 0 respectively so multiplying TRUE by 1 returns 1.

Much the same can be achieved with the double unary --:

=--(A1="")  

where when A1 is empty one minus negates TRUE into -1 and the other negates that to 1 (just + in place of -- however does not change TRUE to 1).

Another solution would be putting call: SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this)
To MileageFeeCalculator constructor like this:

@Service
public class MileageFeeCalculator {

    @Autowired
    private MileageRateService rateService; // <--- will be autowired when constructor is called

    public MileageFeeCalculator() {
        SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this)
    }

    public float mileageCharge(final int miles) {
        return (miles * rateService.ratePerMile()); 
    }
}

Swift

This is a self contained project so that you can see everything in context.

Layout

Create a layout like the following with a UIView and a UIButton. The UIView will be the container in which we will play our video.

Add a video to the project

If you need a sample video to practice with, you can get one from sample-videos.com. I'm using an mp4 format video in this example. Drag and drop the video file into your project. I also had to add it explicitly into the bundle resources (go to Build Phases > Copy Bundle Resources, see this answer for more).

Code

Here is the complete code for the project.

import UIKit
import AVFoundation

class ViewController: UIViewController {
    
    var player: AVPlayer?

    @IBOutlet weak var videoViewContainer: UIView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        initializeVideoPlayerWithVideo()
    }
    
    func initializeVideoPlayerWithVideo() {
        
        // get the path string for the video from assets
        let videoString:String? = Bundle.main.path(forResource: "SampleVideo_360x240_1mb", ofType: "mp4")
        guard let unwrappedVideoPath = videoString else {return}

        // convert the path string to a url
        let videoUrl = URL(fileURLWithPath: unwrappedVideoPath)

        // initialize the video player with the url
        self.player = AVPlayer(url: videoUrl)

        // create a video layer for the player
        let layer: AVPlayerLayer = AVPlayerLayer(player: player)
        
        // make the layer the same size as the container view
        layer.frame = videoViewContainer.bounds
        
        // make the video fill the layer as much as possible while keeping its aspect size
        layer.videoGravity = AVLayerVideoGravity.resizeAspectFill
        
        // add the layer to the container view
        videoViewContainer.layer.addSublayer(layer)
    }

    @IBAction func playVideoButtonTapped(_ sender: UIButton) {
        // play the video if the player is initialized
        player?.play()
    }
}

Notes

• If you are going to be switching in and out different videos, you can use AVPlayerItem.
• If you are only using AVFoundation and AVPlayer, then you have to build all of your own controls. If you want full screen video playback, you can use AVPlayerViewController. You will need to import AVKit for that. It comes with a full set of controls for pause, fast forward, rewind, stop, etc. Here and here are some video tutorials.
• MPMoviePlayerController that you may have seen in other answers is deprecated.

Result

The project should look like this now.

return only makes sense inside a function. There is no function in your code.

Also, your code is worthy if the Department of Redundancy Department. Assuming you move it to a proper function, this would be better:

return confirm(".json_encode($message).");

EDIT much much later: Changed code to use json_encode to ensure the message contents don't break just because of an apostrophe in the message.

If there is not substantial history on one end (aka if it is just a single readme commit on the github end), I often find it easier to manually copy the readme to my local repo and do a git push -f to make my version the new root commit.

I find it is slightly less complicated, doesn't require remembering an obscure flag, and keeps the history a bit cleaner.

SELECT REPLACE(REPLACE(REPLACE(CONVERT(VARCHAR(19), CONVERT(DATETIME, getdate(), 112), 126), '-', ''), 'T', ''), ':', '') 

setTimeout(function(){


},5000); 

Place your code inside of the { }

300 = 0.3 seconds

700 = 0.7 seconds

1000 = 1 second

2000= 2 seconds

2200 = 2.2 seconds

3500 = 3.5 seconds

10000 = 10 seconds

etc.

OR in Kepler follow as shown below :

An update on @kalu's answer, which uses the latest pandas:

def find_duplicated_columns(df):
    dupes = []

    columns = df.columns

    for i in range(len(columns)):
        col1 = df.iloc[:, i]
        for j in range(i + 1, len(columns)):
            col2 = df.iloc[:, j]
            # break early if dtypes aren't the same (helps deal with
            # categorical dtypes)
            if col1.dtype is not col2.dtype:
                break
            # otherwise compare values
            if col1.equals(col2):
                dupes.append(columns[i])
                break

    return dupes

If I understand you well, you need to use to center a container (or block)

margin-left: auto;
margin-right: auto;

and to left align it's contents:

text-align: left;

you need to place the opening brace after main , not before it

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main(void)
{
