mylist[c(5,7,9)] should do it.

You want the sublists returned as sublists of the result list; you don't use [[]] (or rather, the function is [[) for that -- as Dason mentions in comments, [[ grabs the element.

Use the following steps to install curl:

1. Open https://curl.haxx.se/dlwiz?type=bin in a browser.

2. Select your operating system in the dropdown box: either Windows /Win32 or Win 64. Click Select!

3. For Win 32, choose whether you will use curl in a Windows Command Prompt (Generic) or in a Cygwin terminal (cygwin). For Win 64, choose whether you will use curl in a Windows Command Prompt (Generic) or MinGW (MinGW64). Click Select!

4. If required, choose your Windows operating system. Finish.

5. Click Download for the version which has SSL enabled or disabled

6. Open the downloaded zip file. Extract the files to an easy-to-find place, such as C:\Program Files.

Testing curl

1. Open up the Windows Command Prompt terminal. (From the Start menu, click Run, then type cmd.)

2. Set the path to include the directory where you put curl.exe. For example, if you put it in C:\Program Files\curl, then you would type the following command: set path=%path%;"c:\Program Files\curl"

NOTE: You can also directly copy the curl.exe file any existing path in your path

3. Type curl. You should see the following message: curl: try 'curl –help' or 'curl –message' for more information This means that curl is installed and the path is correct.

Look at the HttpServletResponse#sendRedirect(String location) method.

Use it as:

response.sendRedirect(request.getContextPath() + "/welcome.jsp")

Alternatively, look at HttpServletResponse#setHeader(String name, String value) method.

The redirection is set by adding the location header:

response.setHeader("Location", request.getContextPath() + "/welcome.jsp");

Here's a one-liner for using React Router to redirect to an external link:

<Route path='/privacy-policy' component={() => { 
     window.location.href = 'https://example.com/1234'; 
     return null;
}}/>

It uses React pure component concept to reduce the component's code to a single function that, instead of rendering anything, redirects browser to an external URL.

Works both on React Router 3 and 4.

You just do an opposite comparison. if Col2 <= 1. This will return a boolean Series with False values for those greater than 1 and True values for the other. If you convert it to an int64 dtype, True becomes 1 and False become 0,

df['Col3'] = (df['Col2'] <= 1).astype(int)

If you want a more general solution, where you can assign any number to Col3 depending on the value of Col2 you should do something like:

df['Col3'] = df['Col2'].map(lambda x: 42 if x > 1 else 55)

Or:

df['Col3'] = 0
condition = df['Col2'] > 1
df.loc[condition, 'Col3'] = 42
df.loc[~condition, 'Col3'] = 55

<input type="checkbox" onclick="return false" /> will work for you , I am using this

You can calculate the offset of the element and then compare that with the scroll value like:

$(window).scroll(function() {
   var hT = $('#scroll-to').offset().top,
       hH = $('#scroll-to').outerHeight(),
       wH = $(window).height(),
       wS = $(this).scrollTop();
   if (wS > (hT+hH-wH)){
       console.log('H1 on the view!');
   }
});

Updated Demo Fiddle no alert -- instead FadeIn() the element

Updated code to check if the element is inside the viewport or not. Thus this works whether you are scrolling up or down adding some rules to the if statement:

   if (wS > (hT+hH-wH) && (hT > wS) && (wS+wH > hT+hH)){
       //Do something
   }

There are different ways in which properties can be overridden. Assuming you have

.left { background: blue }

e.g. any of the following would override it:

a.background-none { background: none; }
body .background-none { background: none; }
.background-none { background: none !important; }

The first two “win” by selector specificity; the third one wins by !important, a blunt instrument.

You could also organize your style sheets so that e.g. the rule

.background-none { background: none; }

wins simply by order, i.e. by being after an otherwise equally “powerful” rule. But this imposes restrictions and requires you to be careful in any reorganization of style sheets.

These are all examples of the CSS Cascade, a crucial but widely misunderstood concept. It defines the exact rules for resolving conflicts between style sheet rules.

P.S. I used left and background-none as they were used in the question. They are examples of class names that should not be used, since they reflect specific rendering and not structural or semantic roles.

JSFiddle Demonstration

This is what I use with JQuery:

$('.button').on('click', function () { 
    var obj = document.createElement("audio");
        obj.src = "linktoyourfile.wav"; 
        obj.play(); 
});

The main reason is the sys.paths of Python and IPython are different.

Please refer to lucypark link, the solution works in my case. It happen when install opencv by

conda install opencv

And got import error in iPython, There are three steps to solve this issue:

import cv2
ImportError: ...

1. Check path in Python and iPython with following command

import sys
sys.path

You will find different result from Python and Jupyter. Second step, just use sys.path.append to fix the missed path by try-and-error.

2. Temporary solution

In iPython:

import sys
sys.path.append('/home/osboxes/miniconda2/lib/python2.7/site-packages')
import cv2

the ImportError:.. issue solved

3. Permanent solution

Create an iPython profile and set initial append:

In bash shell:

ipython profile create
... CHECK the path prompted , and edit the prompted config file like my case
vi /home/osboxes/.ipython/profile_default/ipython_kernel_config.py

In vi, append to the file:

c.InteractiveShellApp.exec_lines = [
 'import sys; sys.path.append("/home/osboxes/miniconda2/lib/python2.7/site-packages")'
]

Yes, but not how you would imagine. According to caniuse (a very good resource) there is no support and no polyfill available for adding text-shadow support to IE9. However, IE has their own proprietary text shadow (detailed here).

Example implementation, taken from their website (works in IE5.5 through IE9):

p.shadow { 
    filter: progid:DXImageTransform.Microsoft.Shadow(color=#0000FF,direction=45);
}

For cross-browser compatibility and future-proofing of code, remember to also use the CSS3 standard text-shadow property (detailed here). This is especially important considering that IE10 has officially announced their intent to drop support for legacy dx filters. Going forward, IE10+ will only support the CSS3 standard text-shadow.

For those like me just looking for a simple solution, this does almost exactly what you expect from using normal $watch in controllers. The only difference is, that it evaluates the string in it's javascript context and not on a specific scope. You'll have to inject $rootScope into your service, although it is only used to hook into the digest cycles properly.

function watch(target, callback, deep) {
    $rootScope.$watch(function () {return eval(target);}, callback, deep);
};

I think you should edit the anchor tag on bootstrap.css. Otherwise give customized style to the anchor tag with !important (to override the default style on bootstrap.css).

Actually, register tells the compiler that the variable does not alias with anything else in the program (not even char's).

That can be exploited by modern compilers in a variety of situations, and can help the compiler quite a bit in complex code - in simple code the compilers can figure this out on their own.

Otherwise, it serves no purpose and is not used for register allocation. It does not usually incur performance degradation to specify it, as long as your compiler is modern enough.

You can not read & write same file in parallel(Read-write lock). But, we can do parallel operations on temporary data(i.e. Input/output stream). Write the data to file only after closing the input stream. Below steps should be followed.

• Open the file to Input stream
• Open the same file to an Output Stream
• Read and do the processing
• Write contents to output stream.
• Close the read/input stream, close file
• Close output stream, close file.

My test string for the following:

testing='12345,abc,123,54321,ab15234,123456,52341';

If I understand your question, you'd want ["12345", "54321", "15234", "52341"].

If JS engines supported regexp lookbehinds, you could do:

testing.match(/(?<!\d)\d{5}(?!\d)/g)

Since it doesn't currently, you could:

testing.match(/(?:^|\D)(\d{5})(?!\d)/g)

and remove the leading non-digit from appropriate results, or:

pentadigit=/(?:^|\D)(\d{5})(?!\d)/g;
result = [];
while (( match = pentadigit.exec(testing) )) {
    result.push(match[1]);
}

Note that for IE, it seems you need to use a RegExp stored in a variable rather than a literal regexp in the while loop, otherwise you'll get an infinite loop.

I work at an imaging vendor and wrote an adapter for WPF to our image format which is similar to a System.Drawing.Bitmap.

I wrote this KB to explain it to our customers:

http://www.atalasoft.com/kb/article.aspx?id=10156

And there is code there that does it. You need to replace AtalaImage with Bitmap and do the equivalent thing that we are doing -- it should be pretty straightforward.

<select>
    <option selected disabled>Choose one</option>
    <option value="sydney">Sydney</option>
    <option value="melbourne">Melbourne</option>
    <option value="cromwell">Cromwell</option>
    <option value="queenstown">Queenstown</option>
</select>

Using selected and disabled will make "Choose one" be the default selected value, but also make it impossible for the user to actually select the item, like so:

Or in your SQL query wrap that field with IsNull or Coalesce (SQL Server).

Either way works, I like to put that logic in the query so the report has to do less.

you can achive this by calling a function also

<div [style.width.px]="getCustomeWidth()"></div>

  getCustomeWidth() {
    //do what ever you want here
    return customeWidth;

CMD Cheat Sheet

• Cmd.exe

• Getting Help

• Punctuation

• Naming Files

• Starting Programs

• Keys

CMD.exe

First thing to remember its a way of operating a computer. It's the way we did it before WIMP (Windows, Icons, Mouse, Popup menus) became common. It owes it roots to CPM, VMS, and Unix. It was used to start programs and copy and delete files. Also you could change the time and date.

For help on starting CMD type cmd /?. You must start it with either the /k or /c switch unless you just want to type in it.

Getting Help

For general help. Type Help in the command prompt. For each command listed type help <command> (eg help dir) or <command> /? (eg dir /?).

Some commands have sub commands. For example schtasks /create /?.

The NET command's help is unusual. Typing net use /? is brief help. Type net help use for full help. The same applies at the root - net /? is also brief help, use net help.

References in Help to new behaviour are describing changes from CMD in OS/2 and Windows NT4 to the current CMD which is in Windows 2000 and later.

WMIC is a multipurpose command. Type wmic /?.

Punctuation

&    seperates commands on a line.

&&    executes this command only if previous command's errorlevel is 0.

||    (not used above) executes this command only if previous command's 
errorlevel is NOT 0

>    output to a file

>>    append output to a file

<    input from a file

2> Redirects command error output to the file specified. (0 is StdInput, 1 is StdOutput, and 2 is StdError)

2>&1 Redirects command error output to the same location as command output. 

|    output of one command into the input of another command

^    escapes any of the above, including itself, if needed to be passed 
to a program

"    parameters with spaces must be enclosed in quotes

+ used with copy to concatenate files. E.G. copy file1+file2 newfile

, used with copy to indicate missing parameters. This updates the files 
modified date. E.G. copy /b file1,,

%variablename% a inbuilt or user set environmental variable

!variablename! a user set environmental variable expanded at execution 
time, turned with SelLocal EnableDelayedExpansion command

%<number> (%1) the nth command line parameter passed to a batch file. %0 
is the batchfile's name.

%* (%*) the entire command line.

%CMDCMDLINE% - expands to the original command line that invoked the
Command Processor (from set /?).

%<a letter> or %%<a letter> (%A or %%A) the variable in a for loop. 
Single % sign at command prompt and double % sign in a batch file.

\\ (\\servername\sharename\folder\file.ext) access files and folders via UNC naming.

: (win.ini:streamname) accesses an alternative steam. Also separates drive from rest of path.

. (win.ini) the LAST dot in a file path separates the name from extension

. (dir .\*.txt) the current directory

.. (cd ..) the parent directory


\\?\ (\\?\c:\windows\win.ini) When a file path is prefixed with \\?\ filename checks are turned off. 

Naming Files

< > : " / \ | Reserved characters. May not be used in filenames.



Reserved names. These refer to devices eg, 

copy filename con 

which copies a file to the console window.

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, 

COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, 

LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9

CONIN$, CONOUT$, CONERR$

--------------------------------

Maximum path length              260 characters
Maximum path length (\\?\)      32,767 characters (approx - some rare characters use 2 characters of storage)
Maximum filename length        255 characters

Starting a Program

See start /? and call /? for help on all three ways.

There are two types of Windows programs - console or non console (these are called GUI even if they don't have one). Console programs attach to the current console or Windows creates a new console. GUI programs have to explicitly create their own windows.

If a full path isn't given then Windows looks in

1. The directory from which the application loaded.

2. The current directory for the parent process.

3. Windows NT/2000/XP: The 32-bit Windows system directory. Use the GetSystemDirectory function to get the path of this directory. The name of this directory is System32.

4. Windows NT/2000/XP: The 16-bit Windows system directory. There is no function that obtains the path of this directory, but it is searched. The name of this directory is System.

5. The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.

6. The directories that are listed in the PATH environment variable.

Specify a program name

This is the standard way to start a program.

c:\windows\notepad.exe

In a batch file the batch will wait for the program to exit. When typed the command prompt does not wait for graphical programs to exit.

If the program is a batch file control is transferred and the rest of the calling batch file is not executed.

Use Start command

Start starts programs in non standard ways.

start "" c:\windows\notepad.exe

Start starts a program and does not wait. Console programs start in a new window. Using the /b switch forces console programs into the same window, which negates the main purpose of Start.

Start uses the Windows graphical shell - same as typing in WinKey + R (Run dialog). Try

start shell:cache

Also program names registered under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths can also be typed without specifying a full path.

Also note the first set of quotes, if any, MUST be the window title.

Use Call command

Call is used to start batch files and wait for them to exit and continue the current batch file.

Other Filenames

Typing a non program filename is the same as double clicking the file.

Keys

Ctrl + C exits a program without exiting the console window.

For other editing keys type Doskey /?.

• ? and ? recall commands

• ESC clears command line

• F7 displays command history

• ALT+F7 clears command history

• F8 searches command history

• F9 selects a command by number

• ALT+F10 clears macro definitions

Also not listed

• Ctrl + ?or? Moves a word at a time

• Ctrl + Backspace Deletes the previous word

• Home Beginning of line

• End End of line

• Ctrl + End Deletes to end of line

As others have noted, in Notepad++ 6.0 and later, it is possible to use the "Replace" feature to delete all lines that begin with ";" or "#".

Tao provides a regular expression that serves as a starting point, but it does not account for white-space that may exist before the ";" or "#" character on a given line. For example, lines that begin with ";" or "#" but are "tabbed-in" will not be deleted when using Tao's regular expression, ^(#|;).*\r\n.

Tao's regular expression does not account for the caveat mentioned in BoltClock's answer, either: variances in newline characters across systems.

An improvement is to use ^(\s)*(#|;).*(\r\n|\r|\n)?, which accounts for leading white-space and the newline character variances. Also, the trailing ? handles cases in which the last line of the file begins with # or ;, but does not end with a newline.

For the curious, it is possible to discern which type of newline character is used in a given document (and more than one type may be used): View -> Show Symbol -> Show End of Line.

I solved it by global searching the missing directory in the project. then delete any files containing that keyword. it can clean successfully after I remove all the build and .externalNativeBuild directories manually.

function DateDiff(b, e)
{
    let
        endYear = e.getFullYear(),
        endMonth = e.getMonth(),
        years = endYear - b.getFullYear(),
        months = endMonth - b.getMonth(),
        days = e.getDate() - b.getDate();
    if (months < 0)
    {
        years--;
        months += 12;
    }
    if (days < 0)
    {
        months--;
        days += new Date(endYear, endMonth, 0).getDate();
    }
    return [years, months, days];
}

[years, months, days] = DateDiff(
    new Date("October 21, 1980"),
    new Date("July 11, 2017")); // 36 8 20

As explained in Django docs, initial is not default.

• The initial value of a field is intended to be displayed in an HTML . But if the user delete this value, and finally send back a blank value for this field, the initial value is lost. So you do not obtain what is expected by a default behaviour.

• The default behaviour is : the value that validation process will take if data argument do not contain any value for the field.

To implement that, a straightforward way is to combine initial and clean_<field>():

class JournalForm(ModelForm):
    tank = forms.IntegerField(widget=forms.HiddenInput(), initial=123) 

    (...)

    def clean_tank(self):
        if not self['tank'].html_name in self.data:
            return self.fields['tank'].initial
        return self.cleaned_data['tank']

The solution is fairly straight forward. To ensure that we don't impact the width of the cells in the table, we'll turn off white-space. To ensure we get a horizontal scroll bar, we'll turn on overflow-x. And that's pretty much it:

.container {
    width: 30em;
    overflow-x: auto;
    white-space: nowrap;
}

You can see the end-result here, or in the animation below. If the table determines the height of your container, you should not need to explicitly set overflow-y to hidden. But understand that is also an option.

Path is often null. This function is safer.

function Get-ScriptDirectory
{
    $Invocation = (Get-Variable MyInvocation -Scope 1).Value;
    if($Invocation.PSScriptRoot)
    {
        $Invocation.PSScriptRoot;
    }
    Elseif($Invocation.MyCommand.Path)
    {
        Split-Path $Invocation.MyCommand.Path
    }
    else
    {
        $Invocation.InvocationName.Substring(0,$Invocation.InvocationName.LastIndexOf("\"));
    }
}

You're experiencing a strict requirement of the GROUP BY clause. Every column not in the group-by clause must have a function applied to reduce all records for the matching "group" to a single record (sum, max, min, etc).

If you list all queried (selected) columns in the GROUP BY clause, you are essentially requesting that duplicate records be excluded from the result set. That gives the same effect as SELECT DISTINCT which also eliminates duplicate rows from the result set.

The most obvious way to do this would be to print to a file object:

with open('out.txt', 'w') as f:
    print >> f, 'Filename:', filename     # Python 2.x
    print('Filename:', filename, file=f)  # Python 3.x

However, redirecting stdout also works for me. It is probably fine for a one-off script such as this:

import sys

orig_stdout = sys.stdout
f = open('out.txt', 'w')
sys.stdout = f

for i in range(2):
    print('i = ', i)

sys.stdout = orig_stdout
f.close()

Since Python 3.4 there's a simple context manager available to do this in the standard library:

from contextlib import redirect_stdout

with open('out.txt', 'w') as f:
    with redirect_stdout(f):
        print('data')

Redirecting externally from the shell itself is another option, and often preferable:

./script.py > out.txt

Other questions:

What is the first filename in your script? I don't see it initialized.

My first guess is that glob doesn't find any bamfiles, and therefore the for loop doesn't run. Check that the folder exists, and print out bamfiles in your script.

Also, use os.path.join and os.path.basename to manipulate paths and filenames.

If .attr() isn't working for you (especially when checking and unchecking boxes in succession), use .prop() instead of .attr().

I use a List of NameValuePair and URLEncodedUtils to create the url string I want.

protected String addLocationToUrl(String url){
    if(!url.endsWith("?"))
        url += "?";

    List<NameValuePair> params = new LinkedList<NameValuePair>();

    if (lat != 0.0 && lon != 0.0){
        params.add(new BasicNameValuePair("lat", String.valueOf(lat)));
        params.add(new BasicNameValuePair("lon", String.valueOf(lon)));
    }

    if (address != null && address.getPostalCode() != null)
        params.add(new BasicNameValuePair("postalCode", address.getPostalCode()));
    if (address != null && address.getCountryCode() != null)
        params.add(new BasicNameValuePair("country",address.getCountryCode()));

    params.add(new BasicNameValuePair("user", agent.uniqueId));

    String paramString = URLEncodedUtils.format(params, "utf-8");

    url += paramString;
    return url;
}

Detecting sheet of paper is kinda old school. If you want to tackle skew detection then it is better if you straightaway aim for text line detection. With this you will get the extremas left, right, top and bottom. Discard any graphics in the image if you dont want and then do some statistics on the text line segments to find the most occurring angle range or rather angle. This is how you will narrow down to a good skew angle. Now after this you put these parameters the skew angle and the extremas to deskew and chop the image to what is required.

As for the current image requirement, it is better if you try CV_RETR_EXTERNAL instead of CV_RETR_LIST.

Another method of detecting edges is to train a random forests classifier on the paper edges and then use the classifier to get the edge Map. This is by far a robust method but requires training and time.

Random forests will work with low contrast difference scenarios for example white paper on roughly white background.

Use RabbitMQ when:

• You don’t have to handle with Bigdata and you prefer a convenient in-built UI for monitoring
• No need of automatically replicable queues
• No multi subscribers for the messages- Since unlike Kafka which is a log, RabbitMQ is a queue and messages are removed once consumed and acknowledgment arrived
• If you have the requirements to use Wildcards and regex for messages
• If defining message priority is important

In Short: RabbitMQ is good for simple use cases, with low traffic of data, with the benefit of priority queue and flexible routing options. For massive data and high throughput use Kafka.

.fa-file-o {
    position: absolute;
    left: 50px;
    top: 15px;

 <input type="button" name="" value="IMPORT FILE"/>
</div>

Replace: String webServiceUrl = "http://localhost:8080/Service1.asmx"

With : String webServiceUrl = "http://10.0.2.2:8080/Service1.asmx"

Good luck!

I spent a while figuring this out, all I wanted was a simple example of how to do it, so I thought I'd post how I did it. This is some code that updates a library and has a progress dialog showing how many books have been updated and cancels when a user dismisses the dialog:

private class UpdateLibrary extends AsyncTask<Void, Integer, Boolean>{
    private ProgressDialog dialog = new ProgressDialog(Library.this);
    private int total = Library.instance.appState.getAvailableText().length;
    private int count = 0;

    //Used as handler to cancel task if back button is pressed
    private AsyncTask<Void, Integer, Boolean> updateTask = null;

    @Override
    protected void onPreExecute(){
        updateTask = this;
        dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        dialog.setOnDismissListener(new OnDismissListener() {               
            @Override
            public void onDismiss(DialogInterface dialog) {
                updateTask.cancel(true);
            }
        });
        dialog.setMessage("Updating Library...");
        dialog.setMax(total);
        dialog.show();
    }

    @Override
    protected Boolean doInBackground(Void... arg0) {
            for (int i = 0; i < appState.getAvailableText().length;i++){
                if(isCancelled()){
                    break;
                }
                //Do your updating stuff here
            }
        }

    @Override
    protected void onProgressUpdate(Integer... progress){
        count += progress[0];
        dialog.setProgress(count);
    }

    @Override
    protected void onPostExecute(Boolean finished){
        dialog.dismiss();
        if (finished)
            DialogHelper.showMessage(Str.TEXT_UPDATELIBRARY, Str.TEXT_UPDATECOMPLETED, Library.instance);
        else 
            DialogHelper.showMessage(Str.TEXT_UPDATELIBRARY,Str.TEXT_NOUPDATE , Library.instance);
    }
}

The std::string object returned by ss.str() is a temporary object that will have a life time limited to the expression. So you cannot assign a pointer to a temporary object without getting trash.

Now, there is one exception: if you use a const reference to get the temporary object, it is legal to use it for a wider life time. For example you should do:

#include <string>
#include <sstream>
#include <iostream>

using namespace std;

int main()
{
    stringstream ss("this is a string\n");

    string str(ss.str());

    const char* cstr1 = str.c_str();

    const std::string& resultstr = ss.str();
    const char* cstr2 = resultstr.c_str();

    cout << cstr1       // Prints correctly
        << cstr2;       // No more error : cstr2 points to resultstr memory that is still alive as we used the const reference to keep it for a time.

    system("PAUSE");

    return 0;
}

That way you get the string for a longer time.

Now, you have to know that there is a kind of optimisation called RVO that say that if the compiler see an initialization via a function call and that function return a temporary, it will not do the copy but just make the assigned value be the temporary. That way you don't need to actually use a reference, it's only if you want to be sure that it will not copy that it's necessary. So doing:

 std::string resultstr = ss.str();
 const char* cstr2 = resultstr.c_str();

would be better and simpler.

I was recently looking for a nice solution to this without adding React-Bootstrap to my project (as Bootstrap 4 is about to be released).

This is my solution: https://jsfiddle.net/16j1se1q/1/

let Modal = React.createClass({
    componentDidMount(){
        $(this.getDOMNode()).modal('show');
        $(this.getDOMNode()).on('hidden.bs.modal', this.props.handleHideModal);
    },
    render(){
        return (
          <div className="modal fade">
            <div className="modal-dialog">
              <div className="modal-content">
                <div className="modal-header">
                  <button type="button" className="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                  <h4 className="modal-title">Modal title</h4>
                </div>
                <div className="modal-body">
                  <p>One fine body&hellip;</p>
                </div>
                <div className="modal-footer">
                  <button type="button" className="btn btn-default" data-dismiss="modal">Close</button>
                  <button type="button" className="btn btn-primary">Save changes</button>
                </div>
              </div>
            </div>
          </div>
        )
    },
    propTypes:{
        handleHideModal: React.PropTypes.func.isRequired
    }
});



let App = React.createClass({
    getInitialState(){
        return {view: {showModal: false}}
    },
    handleHideModal(){
        this.setState({view: {showModal: false}})
    },
    handleShowModal(){
        this.setState({view: {showModal: true}})
    },
    render(){
    return(
        <div className="row">
            <button className="btn btn-default btn-block" onClick={this.handleShowModal}>Open Modal</button>
            {this.state.view.showModal ? <Modal handleHideModal={this.handleHideModal}/> : null}
        </div>
    );
  }
});

React.render(
   <App />,
    document.getElementById('container')
);

The main idea is to only render the Modal component into the React DOM when it is to be shown (in the App components render function). I keep some 'view' state that indicates whether the Modal is currently shown or not.

The 'componentDidMount' and 'componentWillUnmount' callbacks either hide or show the modal (once it is rendered into the React DOM) via Bootstrap javascript functions.

I think this solution nicely follows the React ethos but suggestions are welcome!

This generalizes and assumes you are normalizing the trailing dimension.

def softmax(x: np.ndarray) -> np.ndarray:
    e_x = np.exp(x - np.max(x, axis=-1)[..., None])
    e_y = e_x.sum(axis=-1)[..., None]
    return e_x / e_y

new Chart('idName', {
      type: 'typeChar',
      data: data,
      options: {
        legend: {
          display: false
        }
      }
    });

If you need exact '/' delimiters, for example: 09/20/2013 rather than 09.20.2013, use escape sequence '/':

Dim regDate As Date = Date.Now()
Dim strDate As String = regDate.ToString("MM\/dd\/yyyy")

About promise composition vs. Rxjs, as this is a frequently asked question, you can refer to a number of previously asked questions on SO, among which :

• How to do the chain sequence in rxjs
• RxJS Promise Composition (passing data)
• RxJS sequence equvalent to promise.then()?

Basically, flatMap is the equivalent of Promise.then.

For your second question, do you want to replay values already emitted, or do you want to process new values as they arrive? In the first case, check the publishReplay operator. In the second case, standard subscription is enough. However you might need to be aware of the cold. vs. hot dichotomy depending on your source (cf. Hot and Cold observables : are there 'hot' and 'cold' operators? for an illustrated explanation of the concept)

In Layman terms, you need to include external js file in your HTML file & thereafter you could directly call your JS method written in an external js file from HTML page. Follow the code snippet for insight:-

caller.html

<script type="text/javascript" src="external.js"></script>
<input type="button" onclick="letMeCallYou()" value="run external javascript">

external.js

function letMeCallYou()
{
    alert("Bazinga!!!  you called letMeCallYou")
}

Result :

It is worth mentioning that 2>&1 means that standard error will be redirected too, together with standard output. So

someCommand | tee someFile

gives you just the standard output in the file, but not the standard error: standard error will appear in console only. To get standard error in the file too, you can use

someCommand 2>&1 | tee someFile

(source: In the shell, what is " 2>&1 "? ). Finally, both the above commands will truncate the file and start clear. If you use a sequence of commands, you may want to get output&error of all of them, one after another. In this case you can use -a flag to "tee" command:

someCommand 2>&1 | tee -a someFile

public List<String> getAllData(String email)
{

    db = this.getReadableDatabase();
    String[] projection={email};

    List<String> list=new ArrayList<>();

    Cursor cursor = db.query(TABLE_USER, //Table to query
            null,    //columns to return
            "user_email=?",        //columns for the WHERE clause
            projection,        //The values for the WHERE clause
            null,       //group the rows
            null,       //filter by row groups
            null);
    //  cursor.moveToFirst();

    if (cursor.moveToFirst()) {
        do {

            list.add(cursor.getString(cursor.getColumnIndex("user_id")));
            list.add(cursor.getString(cursor.getColumnIndex("user_name")));
            list.add(cursor.getString(cursor.getColumnIndex("user_email")));
            list.add(cursor.getString(cursor.getColumnIndex("user_password")));
            // cursor.moveToNext();

        } while (cursor.moveToNext());
    }
    return list;
}

I tried "ManiIOT"'s solution and it worked surprisingly. I've added another role (Compute Admin Role) for my google user account from IAM admin. Then stopped and restarted the VM. Afterwards 'sudo passwd' let me to generate a new password for the user.

So here are steps.

1. Go to IAM & Admin
2. Select IAM
3. Find your user name service account (basically your google account) and click Edit-member
4. Add another role --> select 'Compute Engine' - 'Compute Admin'
5. Restart your Compute VM
6. open SSH shell and run the command 'sudo passwd'
7. enter a brand new password. Voilà!

Yes, methinks you need to arrange your data appropriately. One way would be this:

X <- data.frame(x=rep(x,2),
                y=c(3*x+eps, 2*x+eps),
                case=rep(c("first","second"), each=100))

qplot(x, y, data=X, facets = . ~ case) + geom_smooth()

I am sure there are better tricks in plyr or reshape -- I am still not really up to speed on all these powerful packages by Hadley.

I had the same issue with the filtered index and my inserts and updates were failing. All I did was to change the stored procedure that had the insert and update statement to:

create procedure abc
()
AS
BEGIN
SET NOCOUNT ON
SET NUMERIC_ROUNDABORT OFF
SET CONCAT_NULL_YIELDS_NULL ON 
SET ANSI_WARNINGS ON 
SET ANSI_PADDING ON 
end

Shorter way is do it as follows:

private char[][] table = {{'1', '2', '3'}, {'4', '5', '6'}, {'7', '8', '9'}};

At its core, Git is a set of command line utility programs that are designed to execute on a Unix style command-line environment. Modern operating systems like Linux and macOS both include built-in Unix command line terminals. This makes Linux and macOS complementary operating systems when working with Git. Microsoft Windows instead uses Windows command prompt, a non-Unix terminal environment.

What is Git Bash?

Git Bash is an application for Microsoft Windows environments which provides an emulation layer for a Git command line experience. Bash is an acronym for Bourne Again Shell. A shell is a terminal application used to interface with an operating system through written commands. Bash is a popular default shell on Linux and macOS. Git Bash is a package that installs Bash, some common bash utilities, and Git on a Windows operating system.

It turns out that Google Picasa (free) will do this for you now. If you have it open, when you hit it will save the screen shot to a file and load it into Picasa. In my experience, it works great!

In Python 3,

def filter_nonprintable(text):
    import itertools
    # Use characters of control category
    nonprintable = itertools.chain(range(0x00,0x20),range(0x7f,0xa0))
    # Use translate to remove all non-printable characters
    return text.translate({character:None for character in nonprintable})

See this StackOverflow post on removing punctuation for how .translate() compares to regex & .replace()

The ranges can be generated via nonprintable = (ord(c) for c in (chr(i) for i in range(sys.maxunicode)) if unicodedata.category(c)=='Cc') using the Unicode character database categories as shown by @Ants Aasma.

You can use the following endpoint to get the image.jfif instead of jpg:

https://graph.facebook.com/v3.2/{user-id}/picture

Note that you won't be able to see the image, only download it.

From the structure of your source Object, I would try:

containerObject= new JSONObject(container);
 if(containerObject.has("LabelData")){
  JSONObject innerObject = containerObject.getJSONObject("LabelData");
     if(innerObject.has("video")){
        //Do with video
    }
}

all you are right! other way to getting !

Near the top of the code with the Public Workshop(), I am assumeing this bit,

suitButton = new JCheckBox("Suit");
suitButton.setMnemonic(KeyEvent.VK_Y);


suitButton = new JCheckBox("Denim Jeans");
suitButton.setMnemonic(KeyEvent.VK_U);

should maybe be,

suitButton = new JCheckBox("Suit");
suitButton.setMnemonic(KeyEvent.VK_Y);


denimjeansButton = new JCheckBox("Denim Jeans");
denimjeansButton.setMnemonic(KeyEvent.VK_U);

you need to create a new ssh key by typing the following - ssh-keygen -t rsa

Then you need to add: - heroku keys:add

Then if you type - heroku open

The problem has been solved.

It worked for me anyway, you could give it a try...

An explicit cursor is defined as such in a declaration block:

DECLARE 
CURSOR cur IS 
  SELECT columns FROM table WHERE condition;
BEGIN
...

an implicit cursor is implented directly in a code block:

...
BEGIN
   SELECT columns INTO variables FROM table where condition;
END;
...

group by default order by pk id,so the result
username point avg_time
demo123 100 90 ---> id = 4
demo123456 100 100 ---> id = 7
demo 90 120 ---> id = 1

In Visual Studio, the Tab 'Help'-> 'About Microsoft Visual Studio' should give you the desired infos.

Assuming, that you have root access on the box you can do:

sudo -u postgres psql

If that fails with a database "postgres" does not exists this block.

sudo -u postgres psql template1

Then sudo nano /etc/postgresql/11/main/pg_hba.conf file

local   all         postgres                          ident

For newer versions of PostgreSQL ident actually might be peer.

Inside the psql shell you can give the DB user postgres a password:

ALTER USER postgres PASSWORD 'newPassword';

Simple Explanation by analogy

Imagine you are in a bank, trying to get some money out of your account. But it's dark; the bank is pitch black: there's no light and you can't see your hand in front of your face. You are surrounded by another 20 people. They all look the same. And everybody has the same voice. And everyone is a potential bad guy. In other words, HTTP is stateless.

This bank is a funny type of bank - for the sake of argument here's how things work:

1. you wait in line (or on-line) and you talk to the teller: you make a request to withdraw money, and then
2. you have to wait briefly on the sofa, and 20 minutes later
3. you have to go and actually collect your money from the teller.

But how will the teller tell you apart from everyone else?

The teller can't see or readily recognise you, remember, because the lights are all out. What if your teller gives your $10,000 withdrawal to someone else - the wrong person?! It's absolutely vital that the teller can recognise you as the one who made the withdrawal, so that you can get the money (or resource) that you asked for.

Solution:

When you first appear to the teller, he or she tells you something in secret:

"When ever you are talking to me," says the teller, "you should first identify yourlself as GNASHEU329 - that way I know it's you".

Nobody else knows the secret passcode.

Example of How I Withdrew Cash:

So I decide to go to and chill out for 20 minutes and then later i go to the teller and say "I'd like to collect my withdrawal"

The teller asks me: "who are you??!"

"It's me, Mr George Banks!"

"Prove it!"

And then I tell them my passcode: GNASHEU329

"Certainly Mr Banks!"

That basically is how a session works. It allows one to be uniquely identified in a sea of millions of people. You need to identify yourself every time you deal with the teller.

If you got any questions or are unclear - please post comment and i will try to clear it up for you. The following is not strictly speaking, completely accurate in its terminology, but I hope it's helpful to you in understanding concepts.

Explanation via Pictures:

The idiom (shared by quite a few other languages) for an unused variable is a single underscore _. Code analysers typically won't complain about _ being unused, and programmers will instantly know it's a shortcut for i_dont_care_wtf_you_put_here. There is no way to iterate without having an item variable - as the Zen of Python puts it, "special cases aren't special enough to break the rules".

if you are inside the actual function, you can use arguments.callee as a reference to the function. as in:

button.addEventListener('click', function() {
      ///this will execute only once
      alert('only once!');
      this.removeEventListener('click', arguments.callee);
});

EDIT: This will not work if you are working in strict mode ("use strict";)

Simple extension:

public static bool IsNumeric(this String str)
{
    try
    {
        Double.Parse(str.ToString());
        return true;
    }
    catch {
    }
    return false;
}

You will simply need to do a type check for each of the basic numeric types.

Here's an extension method that should do the job:

public static bool IsNumber(this object value)
{
    return value is sbyte
            || value is byte
            || value is short
            || value is ushort
            || value is int
            || value is uint
            || value is long
            || value is ulong
            || value is float
            || value is double
            || value is decimal;
}

This should cover all numeric types.

Update

It seems you do actually want to parse the number from a string during deserialisation. In this case, it would probably just be best to use double.TryParse.

string value = "123.3";
double num;
if (!double.TryParse(value, out num))
    throw new InvalidOperationException("Value is not a number.");

Of course, this wouldn't handle very large integers/long decimals, but if that is the case you just need to add additional calls to long.TryParse / decimal.TryParse / whatever else.

Have you tried QCoreApplication::applicationDirPath()

qDebug() << "App path : " << qApp->applicationDirPath();

Unfortunately, the Color class constructor in Flutter does not accept a simple hexadecimal string (like #bfeb91 in CSS).

Instead, it requires an integer like 0xFFBFEB91.

So here is we convert a hex string to an integer

A simple function

Give this function a hex string and it will return you a Color!

Color _getColorFromHex(String hexColor) {
  hexColor = hexColor.replaceAll("#", "");
  if (hexColor.length == 6) {
    hexColor = "FF" + hexColor;
  }
  if (hexColor.length == 8) {
    return Color(int.parse("0x$hexColor"));
  }
}

Use it like this

Text(
  'Hello World',
  style: TextStyle(backgroundColor: _getColorFromHex('ff00aa')), // or 'bfeb91', or 'ffbfeb91'
),

As a String extension

Leveraging the power of Dart extensions we can augment String with a function that returns a Color:

extension ColorExtension on String {
  toColor() {
    var hexColor = this.replaceAll("#", "");
    if (hexColor.length == 6) {
      hexColor = "FF" + hexColor;
    }
    if (hexColor.length == 8) {
      return Color(int.parse("0x$hexColor"));
    }
  }
}

Use it like this

Text(
  'Hello World',
  style: TextStyle(backgroundColor: '#bfeb91'.toColor()), // or 'bfeb91', or 'ffbfeb91'
),

Though alluded to in other comments I thought I'd spell it out a bit for those using the "Controller As" syntax:

<div ng-controller="MyController as ctrl">

<form name="ctrl.myForm">
    ...inputs
    Dirty? {{ctrl.myForm.$dirty}}

    <button ng-click="ctrl.saveChanges()">Save</button>
</form>

</div>

Then you can access the FormController in your code like:

function MyController () {
    var vm = this;
    vm.saveChanges = saveChanges;

    function saveChanges() {

       if(vm.myForm.$valid) { 
            // Save to db or whatever.
            vm.myForm.$setPristine();
       }
}

I think the most efficient way to do this is this is using RemoveAt:

rows.RemoveAt(rows.Count - 1)

To open in a new tab use:

target = "_blank"

To open in the same tab use:

target = "_self"

My solution:

def multiply(numbers):
    a = 1
    for num in numbers:
        a *= num
        return a

  pass

I am not sure I understand what you want, but based on what I understood

the x scale seems to be the same, it is the y scale that is not the same, and that is because you specified scales ="free"

you can specify scales = "free_x" to only allow x to be free (in this case it is the same as pred has the same range by definition)

p <- ggplot(plot, aes(x = pred, y = value)) + geom_point(size = 2.5) + theme_bw()
p <- p + facet_wrap(~variable, scales = "free_x")

worked for me, see the picture

I think you were making it too difficult - I do seem to remember one time defining the limits based on a formula with min and max and if faceted I think it used only those values, but I can't find the code

You have to use the index and the Adapter to find out the text you have

See this example of Spinner

public class MyOnItemSelectedListener implements OnItemSelectedListener {

    public void onItemSelected(AdapterView<?> parent,
        View view, int pos, long id) {
      Toast.makeText(parent.getContext()), "The planet is " +
          parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show();
    }

    public void onNothingSelected(AdapterView parent) {
      // Do nothing.
    }
}

One more solution to this may be as follows.

public static String toCamelCase(String str, String... separators) {
    String separatorsRegex = "\\".concat(org.apache.commons.lang3.StringUtils.join(separators, "|\\"));
    List splits = Arrays.asList(str.toLowerCase().split(separatorsRegex));
    String capitalizedString = (String)splits.stream().map(WordUtils::capitalize).reduce("", String::concat);
    return capitalizedString.substring(0, 1).toLowerCase() + capitalizedString.substring(1);
}

<div>
    <p class="some_class">lohrem text (it will be of red color )</p>    
    <div>
        <p class="some_class">lohrem text (it will  NOT be of red color)</p> 
    </div>
    <p class="some_class">lohrem text (it will be  of red color )</p>
</div>

div > p.some_class{
    color:red;
}

All the direct children that are <p> with .some_class would get the style applied to them.

For what its worth if you have a more than a handful of projects, which I do, use:

gcloud init

This will list all your projects and give you the option to change current project settings, add a new project configuration or switch:

Pick configuration to use:
 [1] Re-initialize this configuration [esqimo-preprod] with new settings
 [2] Create a new configuration
 [3] Switch to and re-initialize existing configuration: [default]
 [4] Switch to and re-initialize existing configuration: [project 1]
 [5] Switch to and re-initialize existing configuration: [project 2]
Please enter your numeric choice:

It will always ask you to login and display options for different google accounts that you may have.

Given that I manage multiple organisations and projects this approach lets' me to simply switch between them.

The %c conversion specifier won't automatically skip any leading whitespace, so if there's a stray newline in the input stream (from a previous entry, for example) the scanf call will consume it immediately.

One way around the problem is to put a blank space before the conversion specifier in the format string:

scanf(" %c", &c);

The blank in the format string tells scanf to skip leading whitespace, and the first non-whitespace character will be read with the %c conversion specifier.

Even simpler way is to use

View child = View.inflate(context, R.layout.child, null)
item.addChild(child) //attach to your item

You can use Task Scheduler Managed Wrapper:

using System;
using Microsoft.Win32.TaskScheduler;

class Program
{
   static void Main(string[] args)
   {
      // Get the service on the local machine
      using (TaskService ts = new TaskService())
      {
         // Create a new task definition and assign properties
         TaskDefinition td = ts.NewTask();
         td.RegistrationInfo.Description = "Does something";

         // Create a trigger that will fire the task at this time every other day
         td.Triggers.Add(new DailyTrigger { DaysInterval = 2 });

         // Create an action that will launch Notepad whenever the trigger fires
         td.Actions.Add(new ExecAction("notepad.exe", "c:\\test.log", null));

         // Register the task in the root folder
         ts.RootFolder.RegisterTaskDefinition(@"Test", td);

         // Remove the task we just created
         ts.RootFolder.DeleteTask("Test");
      }
   }
}

Alternatively you can use native API or go for Quartz.NET. See this for details.

We can use the get_locale function:

if (get_locale() == 'en_GB') {
    // drink tea
}

I also got this problem and it caused my sessions not to work. But not to break either...

I used a mongoose connection.

I had this:

var mongoose = require('mongoose');
var express = require('express');
var cookieParser = require('cookie-parser');
var expressSession = require('express-session');
var MongoStore = require('connect-mongo')(expressSession);
...
var app = express();
app.set('port', process.env.PORT || 8080);
app.use(bodyParser);
mongoose.connect('mongodb://localhost/TEST');
var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function callback () {
  console.log('MongoDB connected');
});


app.use(cookieParser());
app.use(expressSession({
  secret: 'mysecret',
  cookie: {
    maxAge: null,
    expires: moment().utc().add('days',10).toDate(),// 10 dagen
  },
  store: new MongoStore({
  db: 'TEST',
  collection: 'sessions',
}),

Very straightforward. But req.session stayed always empty.

rm -rf node_modules
npm cache clean
npm install

Did the trick. Watch out you dont have a 'mongodb' in your package.json! Just Mongoose and connect-mongo.

Modulo is the remainder, not division.

2 / 4 = 0R2
2 % 4 = 2

The sign % is often used for the modulo operator, in lieu of the word mod.

For x % 4, you get the following table (for 1-10)

 x x%4
------
 1  1
 2  2
 3  3
 4  0
 5  1
 6  2
 7  3
 8  0
 9  1
10  2

If you have php 5.3+, you can use an anonymous function like so:

add_filter( 'login_redirect', function() { return site_url('news'); } );

Use position property

style="position: absolute;right:0;top:0"

I recommend using the emulator by Genymotion instead of Google's emulators. It launches way faster and responds almost in real-time. It also supports Google Play Services and therefore Google Maps.

Give it a try! Here is a blog post which helps you setting up the emulator.

Look at http://ss64.com/nt/if.html for an answer; the command is IF [%1]==[] GOTO NO_ARGUMENT or similar.

As I can't comment, I'll expand on Alex's fantastic answer.

If you want the Sublime-like experience with wrapping open up the Keymap Extensions (Preferences > Keymap Extensions [Cmd+K Cmd+M]) and add the following object:

{
    "key": "alt+w",
    "command": "editor.emmet.action.wrapIndividualLinesWithAbbreviation",
    "when": "editorHasSelection && editorTextFocus"
}

Which will bind the Emmet wrap command to Alt+W when text is selected

(Sorry for OSX only instructions)

If you don't like the mangled name, you can dictate your own name:

@objc(CalendarViewController) class CalendarViewController : UIViewController {
    // ...
}

However, it would be better in the long run to learn to parse the mangled name. The format is standard and meaningful and won't change.

Elaborating a bit more on Taylor Gautier's reply (sorry, I dont have enough reputation to add a comment), I'd reply to Dean Richardson on how to do what he wanted, without any additional JS code. Pure CSS.

You would replace his .btn with the following:

<a class="btn showdetails" data-toggle="collapse" data-target="#viewdetails"></a>

And add a small CSS for when the content is displayed:

.in.collapse+a.btn.showdetails:before { 
    content:'Hide details «';
}
.collapse+a.btn.showdetails:before { 
    content:'Show details »'; 
}

Here is his modified example

Take a look here in order to get started: http://instagram.com/developer/

and then in order to retrieve pictures by tag, look here: http://instagram.com/developer/endpoints/tags/

Getting tags from Instagram doesn't require OAuth, so you can make the calls via these URLs:

GET IMAGES https://api.instagram.com/v1/tags/{tag-name}/media/recent?access_token={TOKEN}

SEARCH https://api.instagram.com/v1/tags/search?q={tag-query}&access_token={TOKEN}

TAG INFO https://api.instagram.com/v1/tags/{tag-name}?access_token={TOKEN}

Background image is not supported in Outlook. You have to use an image and position it behind the text using position relative or absolute.

git push -f maybe?

man git-push will tell more.

You need to encode Unicode explicitly before writing to a file, otherwise Python does it for you with the default ASCII codec.

Pick an encoding and stick with it:

f.write(printinfo.encode('utf8') + '\n')

or use io.open() to create a file object that'll encode for you as you write to the file:

import io

f = io.open(filename, 'w', encoding='utf8')

Give BinaryTree<T, Comparator>::Node a subtreeHeight data member, initialized to 0 in its constructor, and update automatically every time with:

template <typename T, typename Comparator>
inline void BinaryTree<T, Comparator>::Node::setLeft (std::shared_ptr<Node>& node) {
    const std::size_t formerLeftSubtreeSize = left ? left->subtreeSize : 0;
    left = node;
    if (node) {
        node->parent = this->shared_from_this();
        subtreeSize++;
        node->depthFromRoot = depthFromRoot + 1;
        const std::size_t h = node->subtreeHeight;
        if (right)
            subtreeHeight = std::max (right->subtreeHeight, h) + 1;
        else
            subtreeHeight = h + 1;
    }
    else {
        subtreeSize -= formerLeftSubtreeSize;
        subtreeHeight = right ? right->subtreeHeight + 1 : 0;
    }
}

template <typename T, typename Comparator>
inline void BinaryTree<T, Comparator>::Node::setRight (std::shared_ptr<Node>& node) {
    const std::size_t formerRightSubtreeSize = right ? right->subtreeSize : 0;
    right = node;
    if (node) {
        node->parent = this->shared_from_this();
        subtreeSize++;
        node->depthFromRoot = depthFromRoot + 1;
        const std::size_t h = node->subtreeHeight;
        if (left)
            subtreeHeight = std::max (left->subtreeHeight, h) + 1;
        else
            subtreeHeight = h + 1;
    }
    else {
        subtreeSize -= formerRightSubtreeSize;
        subtreeHeight = left ? left->subtreeHeight + 1 : 0;
    }
}

Note that data members subtreeSize and depthFromRoot are also updated. These functions are called when inserting a node (all tested), e.g.

template <typename T, typename Comparator>
inline std::shared_ptr<typename BinaryTree<T, Comparator>::Node>
BinaryTree<T, Comparator>::Node::insert (BinaryTree& tree, const T& t, std::shared_ptr<Node>& node) {
    if (!node) {
        std::shared_ptr<Node> newNode = std::make_shared<Node>(tree, t);
        node = newNode;
        return newNode;
    }
    if (getComparator()(t, node->value)) {
        std::shared_ptr<Node> newLeft = insert(tree, t, node->left);
        node->setLeft(newLeft);
    }
    else {
        std::shared_ptr<Node> newRight = insert(tree, t, node->right);
        node->setRight(newRight);
    }
    return node;
}

If removing a node, use a different version of removeLeft and removeRight by replacing subtreeSize++; with subtreeSize--;. Algorithms for rotateLeft and rotateRight can be adapted without much problem either. The following was tested and passed:

template <typename T, typename Comparator>
void BinaryTree<T, Comparator>::rotateLeft (std::shared_ptr<Node>& node) {  // The root of the rotation is 'node', and its right child is the pivot of the rotation.  The pivot will rotate counter-clockwise and become the new parent of 'node'.
    std::shared_ptr<Node> pivot = node->right;
    pivot->subtreeSize = node->subtreeSize;
    pivot->depthFromRoot--;
    node->subtreeSize--;  // Since 'pivot' will no longer be in the subtree rooted at 'node'.
    const std::size_t a = pivot->left ? pivot->left->subtreeHeight + 1 : 0;  // Need to establish node->heightOfSubtree before pivot->heightOfSubtree is established, since pivot->heightOfSubtree depends on it.
    node->subtreeHeight = node->left ? std::max(a, node->left->subtreeHeight + 1) : std::max<std::size_t>(a,1);
    if (pivot->right) {
        node->subtreeSize -= pivot->right->subtreeSize;  // The subtree rooted at 'node' loses the subtree rooted at pivot->right.
        pivot->subtreeHeight = std::max (pivot->right->subtreeHeight, node->subtreeHeight) + 1;
    }
    else
        pivot->subtreeHeight = node->subtreeHeight + 1;
    node->depthFromRoot++;
    decreaseDepthFromRoot(pivot->right);  // Recursive call for the entire subtree rooted at pivot->right.
    increaseDepthFromRoot(node->left);  // Recursive call for the entire subtree rooted at node->left.
    pivot->parent = node->parent;
    if (pivot->parent) {  // pivot's new parent will be its former grandparent, which is not nullptr, so the grandparent must be updated with a new left or right child (depending on whether 'node' was its left or right child).
        if (pivot->parent->left == node)
            pivot->parent->left = pivot;
        else
            pivot->parent->right = pivot;
    }
    node->setRightSimple(pivot->left);  // Since pivot->left->value is less than pivot->value but greater than node->value.  We use the NoSizeAdjustment version because the 'subtreeSize' values of 'node' and 'pivot' are correct already.
    pivot->setLeftSimple(node);
    if (node == root) {
        root = pivot;
        root->parent = nullptr; 
    }
}

where

inline void decreaseDepthFromRoot (std::shared_ptr<Node>& node) {adjustDepthFromRoot(node, -1);}
inline void increaseDepthFromRoot (std::shared_ptr<Node>& node) {adjustDepthFromRoot(node, 1);}

template <typename T, typename Comparator>
inline void BinaryTree<T, Comparator>::adjustDepthFromRoot (std::shared_ptr<Node>& node, int adjustment) {
    if (!node)
        return;
    node->depthFromRoot += adjustment;
    adjustDepthFromRoot (node->left, adjustment);
    adjustDepthFromRoot (node->right, adjustment);
}

Did you import it? Importing matplotlib is not enough.

>>> import matplotlib
>>> matplotlib.pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'

but

>>> import matplotlib.pyplot
>>> matplotlib.pyplot

works.

pyplot is a submodule of matplotlib and not immediately imported when you import matplotlib.

The most common form of importing pyplot is

import matplotlib.pyplot as plt

Thus, your statements won't be too long, e.g.

plt.plot([1,2,3,4,5])

instead of

matplotlib.pyplot.plot([1,2,3,4,5])

And: pyplot is not a function, it's a module! So don't call it, use the functions defined inside this module instead. See my example above

You'll need to install numpy, scipy and matplotlib to get pylab. In ubuntu you can install them with this command:

sudo apt-get install python-numpy python-scipy python-matplotlib

If you installed python from source you will need to install these packages through pip. Note that you may have to install other dependencies to do this, as well as install numpy before the other two.

That said, I would recommend using the version of python in the repositories as I think it is up to date with the current version of python (2.7.3).

If you are trying to maintain the same aspect ratio, then wouldn't you resize by some percentage of the original size?

For example, half the original size

half = 0.5
out = im.resize( [int(half * s) for s in im.size] )

you can get the nodejs configuration from http://nodejs.org/
The important thing you need to keep in your mind is about its configuration in file app.js which consists of port number host and other settings these are settings working for me

backendSettings = {
"scheme":"https / http ",
"host":"Your website url",
"port":49165, //port number 
'sslKeyPath': 'Path for key',
'sslCertPath': 'path for SSL certificate',
'sslCAPath': '',
"resource":"/socket.io",
"baseAuthPath": '/nodejs/',
"publishUrl":"publish",
"serviceKey":"",
"backend":{
"port":443,
"scheme": 'https / http', //whatever is your website scheme
"host":"host name",
"messagePath":"/nodejs/message/"},
"clientsCanWriteToChannels":false,
"clientsCanWriteToClients":false,
"extensions":"",
"debug":false,
"addUserToChannelUrl": 'user/channel/add/:channel/:uid',
"publishMessageToContentChannelUrl": 'content/token/message',
"transports":["websocket",
"flashsocket",
"htmlfile",
"xhr-polling",
"jsonp-polling"],
"jsMinification":true,
"jsEtag":true,
"logLevel":1};

In this if you are getting "Error: listen EADDRINUSE" then please change the port number i.e, here I am using "49165" so you can use other port such as 49170 or some other port. For this you can refer to the following article
http://www.a2hosting.com/kb/installable-applications/manual-installations/installing-node-js-on-shared-hosting-accounts

My gut told me the same thing when I came across this design.

I am working on a code base where there are three dbContexts to one database. 2 out of the 3 dbcontexts are dependent on information from 1 dbcontext because it serves up the administrative data. This design has placed constraints on how you can query your data. I ran into this problem where you cannot join across dbcontexts. Instead what you are required to do is query the two separate dbcontexts then do a join in memory or iterate through both to get the combination of the two as a result set. The problem with that is instead of querying for a specific result set you are now loading all your records into memory and then doing a join against the two result sets in memory. It can really slow things down.

I would ask the question "just because you can, should you?"

See this article for the problem I came across related to this design. The specified LINQ expression contains references to queries that are associated with different contexts

import warnings
warnings.warn("Warning...........Message")

See the python documentation: here

Have a look at C++11 Features (Modern C++)

and section "Quick Reference Guide to Visual C++ Version Numbers" ...

You can set a reference to the Scripting.Runtime library and then use the FileSystemObject. It has a DeleteFile method and a FileExists method.

See the MSDN article here.

Do this programatically in obj c

UIView *view = [[UIView alloc] initWithFrame:CGRectMake(20, 50,    200, 200)];

view.layer.backgroundColor = [UIColor whiteColor].CGColor;
view.layer.cornerRadius = 20.0;
view.layer.frame = CGRectInset(v.layer.frame, 20, 20);

[view.layer.shadowOffset = CGSizeMake(1, 0);
view.layer.shadowColor = [[UIColor blackColor] CGColor];
view.layer.shadowRadius = 5;
view.layer.shadowOpacity = .25;][1]

[self.view addSubview:view];

We Can Also do this from stoaryboard.

 layer.cornerRadius  Number  5

You can use this api https://code.google.com/p/google-gson/
It's simple and very useful,

Here's how to use the https://code.google.com/p/google-gson/ Api to resolve your problem

public class Test {
  public static void main(String... strings) throws FileNotFoundException  {
    Reader reader = new FileReader(new File("<fullPath>/json.js"));
    JsonElement elem = new JsonParser().parse(reader);
    Gson gson  = new GsonBuilder().create();
   TestObject o = gson.fromJson(elem, TestObject.class);
   System.out.println(o);
  }


}

class TestObject{
  public String fName;
  public String lName;
  public String toString() {
    return fName +" "+lName;
  }
}

json.js file content :

{"fName":"Mohamed",
"lName":"Ali"
}

I had this problem as well and what I did to fix it, AND still use the Holo theme was to take these steps:

first I replaced this import:

import android.support.v7.app.AppCompatActivity;

with this one:

import android.app.Activity;

then changed my extension from:

public class MyClass extends AppCompatActivity {//...

to this:

public class MyClass extends Activity {//...

And also had to change this import:

import android.support.v7.app.AlertDialog;

to this import:

import android.app.AlertDialog;

and then you can use your theme tag in the manifest at the activity level:

android:theme="@android:style/Theme.Holo.Dialog" />

and lastly, (unless you have other classes in your project that has to use v7 appCompat) you can either clean and rebuild your project or delete this entry in the gradle build file at the app level:

compile 'com.android.support:appcompat-v7:23.2.1'

if you have other classes in your project that has to use v7 appCompat then just clean and rebuild the project.

If you want to keep a small code base, and you are only going to be needing the toggle button for a small part of the application. I would suggest instead maintain you're javascript code your self (angularjs, javascript, jquery) and just use plain CSS.

Good toggle button generator: https://proto.io/freebies/onoff/

Using Node.js v12.2.0, I can import all standard modules like this:

import * as Http from 'http'
import * as Fs from 'fs'
import * as Path from 'path'
import * as Readline from 'readline'
import * as Os from 'os'

Versus what I did before:

const
  Http = require('http')
  ,Fs = require('fs')
  ,Path = require('path')
  ,Readline = require('readline')
  ,Os = require('os')

Any module that is an ECMAScript module can be imported without having to use an .mjs extension as long as it has this field in its package.json file:

"type": "module"

So make sure you put such a package.json file in the same folder as the module you're making.

And to import modules not updated with ECMAScript module support, you can do like this:

// Implement the old require function
import { createRequire } from 'module'
const require = createRequire(import.meta.url)

// Now you can require whatever
const
  WebSocket = require('ws')
  ,Mime = require('mime-types')
  ,Chokidar = require('chokidar')

And of course, do not forget that this is needed to actually run a script using module imports (not needed after v13.2):

node --experimental-modules my-script-that-use-import.js

And that the parent folder needs this package.json file for that script to not complain about the import syntax:

{
  "type": "module"
}

If the module you want to use has not been updated to support being imported using the import syntax then you have no other choice than using require (but with my solution above that is not a problem).

I also want to share this piece of code which implements the missing __filename and __dirname constants in modules:

import {fileURLToPath} from 'url'
import {dirname} from 'path'
const __filename = fileURLToPath(import.meta.url)
const __dirname = dirname(__filename)

For int %d

For long int %ld

For long long int %lld

For unsigned long long int %llu

With the mechanism explained in the answer of Jan I have instructed the m2e pluging to ignore the goal "generate-application-xml". This gets rid of the error and seems to work since m2e creates application.xml.

So basically the error forced us to decide which mechanism is in charge for generating application.xml when the Maven build runs inside Eclipse under the control of the m2e plugin. And we have decided that m2e is in charge.

We had a problem like this some weeks before. If you set a breakpoint and have a deep look into this.Controls, the problem reveals it's nature: you have to recurse through all child controls.

The code could look like this:

private void CleanForm()
{
    traverseControlsAndSetTextEmpty(this);
}
private void traverseControlsAndSetTextEmpty(Control control)
{

    foreach(var c in control.Controls)
    {
        if (c is TextBox) ((TextBox)c).Text = String.Empty;
        traverseControlsAndSetTextEmpty(c);
    }
}

The .addwithvalue needs dbnull. You could do something like this:

DateTime? someDate = null;
//...
if (someDate == null)
    myCommand.Parameters.AddWithValue("@SurgeryDate", DBnull.value);

or use a method extension...

  public static class Extensions
    {
        public static SqlParameter AddWithNullValue(this SqlParameterCollection collection, string parameterName, object value)
        {
            if (value == null)
                return collection.AddWithValue(parameterName, DBNull.Value);
            else
                return collection.AddWithValue(parameterName, value);
        }
    }

After searching and giving hit and trial session I am able to solove it by first specifying url like

$window.location.href = '/#/home/stats';

then reload

$window.location.reload();

Referencing Qwerty's answer, you can avoid to inflate XL size by re-using cellStyle. And when the type is CELL_TYPE_BLANK, getStringCellValue returns "" instead of null.

private static void copyRow(Sheet worksheet, int sourceRowNum, int destinationRowNum) {
  // Get the source / new row
  Row newRow = worksheet.getRow(destinationRowNum);
  Row sourceRow = worksheet.getRow(sourceRowNum);

  // If the row exist in destination, push down all rows by 1 else create a new row
  if (newRow != null) {
    worksheet.shiftRows(destinationRowNum, worksheet.getLastRowNum(), 1);
  } else {
    newRow = worksheet.createRow(destinationRowNum);
  }

  // Loop through source columns to add to new row
  for (int i = 0; i < sourceRow.getLastCellNum(); i++) {
    // Grab a copy of the old/new cell
    Cell oldCell = sourceRow.getCell(i);
    Cell newCell = newRow.createCell(i);

    // If the old cell is null jump to next cell
    if (oldCell == null) {
      newCell = null;
      continue;
    }

    // Use old cell style
    newCell.setCellStyle(oldCell.getCellStyle());

    // If there is a cell comment, copy
    if (newCell.getCellComment() != null) {
      newCell.setCellComment(oldCell.getCellComment());
    }

    // If there is a cell hyperlink, copy
    if (oldCell.getHyperlink() != null) {
      newCell.setHyperlink(oldCell.getHyperlink());
    }

    // Set the cell data type
    newCell.setCellType(oldCell.getCellType());

    // Set the cell data value
    switch (oldCell.getCellType()) {
    case Cell.CELL_TYPE_BLANK:
      break;
    case Cell.CELL_TYPE_BOOLEAN:
      newCell.setCellValue(oldCell.getBooleanCellValue());
      break;
    case Cell.CELL_TYPE_ERROR:
      newCell.setCellErrorValue(oldCell.getErrorCellValue());
      break;
    case Cell.CELL_TYPE_FORMULA:
      newCell.setCellFormula(oldCell.getCellFormula());
      break;
    case Cell.CELL_TYPE_NUMERIC:
      newCell.setCellValue(oldCell.getNumericCellValue());
      break;
    case Cell.CELL_TYPE_STRING:
      newCell.setCellValue(oldCell.getRichStringCellValue());
      break;
    }
  }
}

A very simple way is to use Formatter (see date time conversions) or more directly String.format as in

String.format("%tR", new Date())

Write this in your View Controller class of your Tab Bar:

// Generate a black tab bar
self.tabBarController.tabBar.barTintColor = [UIColor blackColor];

// Set the selected icons and text tint color
self.tabBarController.tabBar.tintColor = [UIColor orangeColor];

In Java System.out.println() will print to the standard out of the system you are using. On the other hand, System.err.println() will print to the standard error.

If you are using a simple Java console application, both outputs will be the same (the command line or console) but you can reconfigure the streams so that for example, System.out still prints to the console but System.err writes to a file.

Also, IDEs like Eclipse show System.err in red text and System.out in black text by default.

One important distinction between the two (which is visible in the Reflected code) is that SelectedValue will return an empty string if a nothing is selected, whereas SelectedItem.Value will throw a NullReference exception.

this is the nasty child of your code :)

.container, .navbar-static-top .container, .navbar-fixed-top .container, .navbar-fixed-bottom .container {
width: 1170px;
}

replace it with

.container, .navbar-static-top .container, .navbar-fixed-top .container, .navbar-fixed-bottom .container {
width: 100%;
}

Probably the easiest way would be use this app Hosts Editor . You need to have root

You can use INSERT...SELECT syntax. Note that you can quote '1' directly in the SELECT part.

INSERT INTO mt_magazine_subscription ( 
      magazine_subscription_id, 
      subscription_name, 
      magazine_id, 
      status ) 
SELECT magazine_subscription_id, 
       subscription_name, 
       magazine_id, 
       '1'
FROM tbl_magazine_subscription
ORDER BY magazine_subscription_id ASC 

This is working when i press button to change text language of my TextView.(strings.xml in values-de folder)

String languageToLoad = "de"; // your language
Configuration config = getBaseContext().getResources().getConfiguration();
Locale locale = new Locale(languageToLoad);
Locale.setDefault(locale);
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
recreate();

This should do the trick:

models.DateTimeField(_("Date"), auto_now_add = True)

Try this:

From the libraries tab:

Eclipse -> right click on project name in sidebar -> configure build path -> Libraries

Remove your web app libraries:

click on "Web App Libraries" -> click "remove"

Add them back in:

click "Add Library" -> click to highlight "Web App Libraries" -> click "next" -> confirm your desired project is the selected option -> click "Finish"

Highlighting "Web App Libraries":

That should work:

function get_content(){
   var p = document.getElementById("txt");
   var spans = p.getElementsByTagName("span");
   var text = '';
   for (var i = 0; i < spans.length; i++){
       text += spans[i].innerHTML;
   }

   p.innerHTML = text;
}

Try this fiddle: http://jsfiddle.net/7gnyc/2/

You should also check you JSON (not in DevTools, but on a backend). Angular HttpClient having a hard time parsing JSON with \0 characters and DevTools will ignore then, so it's quite hard to spot in Chrome.

Based on this article

If you need a fully qualified domain name and have no HTTP request, on Linux, you could use:

var child_process = require("child_process");

child_process.exec("hostname -f", function(err, stdout, stderr) {
  var hostname = stdout.trim();
});

I have personally found pywinrm library to be very effective. However, it does require some commands to be run on the machine and some other setup before it will work.

1st Understand the java.util.Date class

1.1 How to obtain current Date

import java.util.Date;

class Demostration{
    public static void main(String[]args){
        Date date = new Date(); // date object
        System.out.println(date); // Try to print the date object
    }
}

1.2 How to use getTime() method

import java.util.Date;
public class Main {
    public static void main(String[]args){
        Date date = new Date();
        long timeInMilliSeconds = date.getTime();
        System.out.println(timeInMilliSeconds);
    }
}

This will return the number of milliseconds since January 1, 1970, 00:00:00 GMT for time comparison purposes.

1.3 How to format time using SimpleDateFormat class

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;

|| is the conditional OR operator in C#

You probably had a hard time finding it because it's difficult to search for something whose name you don't know. Next time try doing a Google search for "C# Operators" and look at the logical operators.

Here is a list of C# operators.

My code is:

if (title == "User greeting" || "User name") {do stuff};

and my error is:

Error 1 Operator '||' cannot be applied to operands of type 'bool' and 'string' C:\Documents and Settings\Sky View Barns\My Documents\Visual Studio 2005\Projects\FOL Ministry\FOL Ministry\Downloader.cs 63 21 FOL Ministry

You need to do this instead:

if (title == "User greeting" || title == "User name") {do stuff};

The OR operator evaluates the expressions on both sides the same way. In your example, you are operating on the expression title == "User greeting" (a bool) and the expression "User name" (a string). These can't be combined directly without a cast or conversion, which is why you're getting the error.

In addition, it is worth noting that the || operator uses "short-circuit evaluation". This means that if the first expression evaluates to true, the second expression is not evaluated because it doesn't have to be - the end result will always be true. Sometimes you can take advantage of this during optimization.

One last quick note - I often write my conditionals with nested parentheses like this:

if ((title == "User greeting") || (title == "User name")) {do stuff};

This way I can control precedence and don't have to worry about the order of operations. It's probably overkill here, but it's especially useful when the logic gets complicated.

As you read through the examples below, just keep in mind this difference

true === true // true
"string" === true // false
1 === true // false
{} === true // false

But

Boolean("string") === true // true
Boolean(1) === true // true
Boolean({}) === true // true

1. expect(statement).toBe(true)

Assertion passes when the statement passed to expect() evaluates to true

expect(true).toBe(true) // pass
expect("123" === "123").toBe(true) // pass

In all other cases cases it would fail

expect("string").toBe(true) // fail
expect(1).toBe(true); // fail
expect({}).toBe(true) // fail

Even though all of these statements would evaluate to true when doing Boolean():

So you can think of it as 'strict' comparison

2. expect(statement).toBeTrue()

This one does exactly the same type of comparison as .toBe(true), but was introduced in Jasmine recently in version 3.5.0 on Sep 20, 2019

3. expect(statement).toBeTruthy()

toBeTruthy on the other hand, evaluates the output of the statement into boolean first and then does comparison

expect(false).toBeTruthy() // fail
expect(null).toBeTruthy() // fail
expect(undefined).toBeTruthy() // fail
expect(NaN).toBeTruthy() // fail
expect("").toBeTruthy() // fail
expect(0).toBeTruthy() // fail

And IN ALL OTHER CASES it would pass, for example

expect("string").toBeTruthy() // pass
expect(1).toBeTruthy() // pass
expect({}).toBeTruthy() // pass

another way would be to use dplyr package:

x = c(1,1,2,3,4,4,4)
dplyr::distinct(as.data.frame(x))

This works for me:

android {
   packagingOptions {
       exclude 'LICENSE.txt'
   }
}

Ok so i struggled for a long time trying to figure this out. Here is the nuclear option, for when you have exhausted all other ways..

• Make a new folder on your pc.
• Download a brand new installation of angular - I used this guide: https://coursetro.com/posts/code/55/How-to-Install-an-Angular-4-App
• Run it, make sure it works
• Then install your dependancies one by one from your package.json file
• Run it after each one is installed

When you are done, and it still works, import your actual code into this new project. Fix any compile errors the newer version of angular causes.

Thats what did it for me.. 1 hour of rework vs 6 hours of trying to figure out wtf was wrong.. wish i did it this way to start..

.show() and .hide() modify the css display rule. I think you want:

$(selector).css('visibility', 'hidden'); // Hide element
$(selector).css('visibility', 'visible'); // Show element

Try the os.path.exists function

if not os.path.exists(dir):
    os.mkdir(dir)

For Mac users, a MUCH easier way is to do this right in the android emulator:

• click and hold for a second or two
• release click
• the option 'paste' will appear as follow

Running ionic info on your project directory give all the info you need the npm version, cli, app script and some more

For some reason none of the above Answers worked for me. As I need to pass several extra vars to my playbook in Ansbile 2.2.0, this is how I got it working (note the -e option before each var):

ansible-playbook site.yaml -i hostinv -e firstvar=false -e second_var=value2

I´d say MoDisco is by far the most powerful one (though probably not the easiest one to work with).

MoDisco is a generic reverse engineering framework (so that you can customize your reverse engineering project, with MoDisco you can even reverse engineer the behaviour of the java methods, not only the structure and signatures) but also includes some predefined features like the generation of class diagrams out of Java code that you need.

In many cases, continuing to scrape data from a website even when the server is requesting you not to is unethical. However, in the cases where it isn't, you can utilize a list of public proxies in order to scrape a website with many different IP addresses.

This worked for me ::-

mysql --host=hostNameorIp --user=username --password=password  

or

mysql --host=hostNameorIp --user=username --password=password database_name

the error i received was:

cockpit.socket: Failed to listen on sockets: Address already in use

the fix I discovered is:

1. I had to disable selinux

2. in /usr/lib/systemd/system/cockpit service i changed the line :

   #ExecStartPre=/usr/sbin/remotectl certificate --ensure --user=root --group=cockpit-ws --selinux-type=etc_t
   

   to:

   #ExecStartPre=/usr/sbin/remotectl certificate --ensure --user=root --group=cockpit-ws 
   

so as you can see i took out the argument about selinux then i ran:

systemctl daemon-reload
systemctl start cockpit.service

then I browsed to:

I accepted the self-signed certificate and was able to login successfully to cockpit and use it normally.

this is all on a fedora25 machine. the 9090 port had already been added using firewall-cmd

The 2 concurrent requests is an intentional part of the design of many browsers. There is a standard out there that "good http clients" adhere to on purpose. Check out this RFC to see why.

Please write following code in menu.xml file:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:my_menu_tutorial_app="http://schemas.android.com/apk/res-auto"
      xmlns:tools="http://schemas.android.com/tools"
      tools:context="com.example.mymenus.menu_app.MainActivity">
<item android:id="@+id/item_one"
      android:icon="@drawable/menu_icon"
      android:orderInCategory="l01"
      android:title="Item One"
      my_menu_tutorial_app:showAsAction="always">
      <!--sub-menu-->
      <menu>
          <item android:id="@+id/sub_one"
                android:title="Sub-menu item one" />
          <item android:id="@+id/sub_two"
                android:title="Sub-menu item two" />
      </menu>

Also write this java code in activity class file:

public boolean onOptionsItemSelected(MenuItem item)
{
    super.onOptionsItemSelected(item);
    Toast.makeText(this, "Menus item selected: " +
        item.getTitle(), Toast.LENGTH_SHORT).show();
    switch (item.getItemId())
    {
        case R.id.sub_one:
            isItemOneSelected = true;
            supportInvalidateOptionsMenu();
            return true;
        case MENU_ITEM + 1:
            isRemoveItem = true;
            supportInvalidateOptionsMenu();
            return true;
        default:
            return false;
    }
}

This is the easiest way to display menus in action bar.

Working with just one selector:

select {
    width: 268px;
    padding: 5px;
    font-size: 16px;
    line-height: 1;

    border-radius: 5px;
    height: 34px;

There is no need to use the classpath: protocol in your schemaLocation URL if the namespace is configured correctly and the XSD file is on your classpath.

Spring doc "Registering the handler and the schema" shows how it should be done.

In your case, the problem was probably that the spring-context jar on your classpath was not 2.1. That was why changing the protocol to classpath: and putting the specific 2.1 XSD in your classpath fixed the problem.

From what I've seen, there are 2 schemas defined for the main XSD contained in a spring-* jar. Once to resolve the schema URL with the version and once without it.

As an example see this part of the spring.schemas contents in spring-context-3.0.5.RELEASE.jar:

http\://www.springframework.org/schema/context/spring-context-2.5.xsd=org/springframework/context/config/spring-context-2.5.xsd
http\://www.springframework.org/schema/context/spring-context-3.0.xsd=org/springframework/context/config/spring-context-3.0.xsd
http\://www.springframework.org/schema/context/spring-context.xsd=org/springframework/context/config/spring-context-3.0.xsd

This means that (in xsi:schemaLocation)

http://www.springframework.org/schema/context/spring-context-2.5.xsd 

will be validated against

org/springframework/context/config/spring-context-2.5.xsd 

in the classpath.

http://www.springframework.org/schema/context/spring-context-3.0.xsd 

or

http://www.springframework.org/schema/context/spring-context.xsd

will be validated against

org/springframework/context/config/spring-context-3.0.xsd 

in the classpath.

http://www.springframework.org/schema/context/spring-context-2.1.xsd

is not defined so Spring will look for it using the literal URL defined in schemaLocation.

Parsing the query string is a bit more complicated than it seems, depending on how forgiving you want to be.

First, the query string is ascii bytes. You read in these bytes one at a time and convert them to characters. If the character is ? or & then it signals the start of a parameter name. If the character is = then it signals the start of a paramter value. If the character is % then it signals the start of an encoded byte. Here is where it gets tricky.

When you read in a % char you have to read the next two bytes and interpret them as hex digits. That means the next two bytes will be 0-9, a-f or A-F. Glue these two hex digits together to get your byte value. But remember, bytes are not characters. You have to know what encoding was used to encode the characters. The character é does not encode the same in UTF-8 as it does in ISO-8859-1. In general it's impossible to know what encoding was used for a given character set. I always use UTF-8 because my web site is configured to always serve everything using UTF-8 but in practice you can't be certain. Some user-agents will tell you the character encoding in the request; you can try to read that if you have a full HTTP request. If you just have a url in isolation, good luck.

Anyway, assuming you are using UTF-8 or some other multi-byte character encoding, now that you've decoded one encoded byte you have to set it aside until you capture the next byte. You need all the encoded bytes that are together because you can't url-decode properly one byte at a time. Set aside all the bytes that are together then decode them all at once to reconstruct your character.

Plus it gets more fun if you want to be lenient and account for user-agents that mangle urls. For example, some webmail clients double-encode things. Or double up the ?&= chars (for example: http://yoursite.com/blah??p1==v1&&p2==v2). If you want to try to gracefully deal with this, you will need to add more logic to your parser.

You can take a look here for a longer list of screen sizes and respective media queries.

Or go for Bootstrap media queries:

/* Large desktop */
@media (min-width: 1200px) { ... }

/* Portrait tablet to landscape and desktop */
@media (min-width: 768px) and (max-width: 979px) { ... }

/* Landscape phone to portrait tablet */
@media (max-width: 767px) { ... }

/* Landscape phones and down */
@media (max-width: 480px) { ... }

Additionally you might wanty to take a look at Foundation's media queries with the following default settings:

// Media Queries

$screenSmall: 768px !default;
$screenMedium: 1279px !default;
$screenXlarge: 1441px !default;

"response.redirect" and "server.transfer" helps to transfer user from one page to other page while the page is executing. But the way they do this transfer / redirect is very different.

In case you are visual guy and would like see demonstration rather than theory I would suggest to see the below facebook video which explains the difference in a more demonstrative way.

https://www.facebook.com/photo.php?v=762186150488997

The main difference between them is who does the transfer. In "response.redirect" the transfer is done by the browser while in "server.transfer" it’s done by the server. Let us try to understand this statement in a more detail manner.

In "Server.Transfer" following is the sequence of how transfer happens:-

1.User sends a request to an ASP.NET page. In the below figure the request is sent to "WebForm1" and we would like to navigate to "Webform2".

2.Server starts executing "Webform1" and the life cycle of the page starts. But before the complete life cycle of the page is completed “Server.transfer” happens to "WebForm2".

3."Webform2" page object is created, full page life cycle is executed and output HTML response is then sent to the browser.

While in "Response.Redirect" following is the sequence of events for navigation:-

1.Client (browser) sends a request to a page. In the below figure the request is sent to "WebForm1" and we would like to navigate to "Webform2".

2.Life cycle of "Webform1" starts executing. But in between of the life cycle "Response.Redirect" happens.

3.Now rather than server doing a redirect , he sends a HTTP 302 command to the browser. This command tells the browser that he has to initiate a GET request to "Webform2.aspx" page.

4.Browser interprets the 302 command and sends a GET request for "Webform2.aspx".

In other words "Server.Transfer" is executed by the server while "Response.Redirect" is executed by thr browser. "Response.Redirect" needs to two requests to do a redirect of the page.

So when to use "Server.Transfer" and when to use "Response.Redirect" ?

Use "Server.Transfer" when you want to navigate pages which reside on the same server, use "Response.Redirect" when you want to navigate between pages which resides on different server and domain.

Below is a summary table of which chalks out differences and in which scenario to use.

Creating a table and copying the data in a single command:

create table T_NEW as
  select * from T;

* This will not copy PKs, FKs, Triggers, etc.

No need for jQuery unless you target old browsers and don't want to use shims.

var yahooOnly = JSON.parse(jsondata).filter(function (entry) {
    return entry.website === 'yahoo';
});

In ES2015:

const yahooOnly = JSON.parse(jsondata).filter(({website}) => website === 'yahoo');

This works for me:

git pull origin <sha>

e.g.

[dbn src]$ git fetch
[dbn src]$ git status
On branch current_feature
Your branch and 'origin/master' have diverged,
and have 2 and 7 different commits each, respectively.
...
[dbn src]$ git log -3 --pretty=oneline origin/master
f4d10ad2a5eda447bea53fed0b421106dbecea66 CASE-ID1: some descriptive msg
28eb00a42e682e32bdc92e5753a4a9c315f62b42 CASE-ID2: I'm so good at writing commit titles
ff39e46b18a66b21bc1eed81a0974e5c7de6a3e5 CASE-ID2: woooooo
[dbn src]$ git pull origin 28eb00a42e682e32bdc92e5753a4a9c315f62b42
[dbn src]$ git status
On branch current_feature
Your branch and 'origin/master' have diverged,
and have 2 and 1 different commits each, respectively.
...

This pulls 28eb00, ff39e4, and everything before, but doesn't pull f4d10ad. It allows the use of pull --rebase, and honors pull settings in your gitconfig. This works because you're basically treating 28eb00 as a branch.

For the version of git that I'm using, this method requires a full commit hash - no abbreviations or aliases are allowed. You could do something like:

[dbn src]$ git pull origin `git rev-parse origin/master^`

You can use this code,

<?php
     $var = "This is Ashok's Pen.";
     addslashes($var);
?>

if mysqli_real_escape_string() does not work.

You can give to_s a base other than 10:

10.to_s(16)  #=> "a"

Note that in ruby 2.4 FixNum and BigNum were unified in the Integer class. If you are using an older ruby check the documentation of FixNum#to_s and BigNum#to_s

I had the same problem on Mac 10.7.5 with git version 1.7.12.4

When I ran gitk I got an error:

"Error in startup script: expected version number but got "Git-37)"
    while executing
"package vcompare $git_version "1.6.6.2""
    invoked from within
"if {[package vcompare $git_version "1.6.6.2"] >= 0} {
    set show_notes "--show-notes"
}"
    (file "/usr/bin/gitk" line 11587)

When I looked at the code in gitk I saw the line that sets the version.

set git_version [join [lrange [split [lindex [exec git version] end] .] 0 2] .]

This somehow parsed the git version results to Git-37 instead of 1.7.12.4

I just replaced the git_version line with:

set git_version "1.7.12.4"

I did all things necessary to add bundling to an MVC 3 web (I'm new to the existing solution). Styles.Render didn't work for me. I finally discovered I was simply missing a colon. In a master page: <%: Styles.Render("~/Content/Css") %> I'm still confused about why (on the same page) <% Html.RenderPartial("LogOnUserControl"); %> works without the colon.

3 steps:

1. Check the sorce code (HTML) of YouTube, you'll get the link like this (http%253A%252F%252Fo-o.preferred.telemar-cnf1.v18.lscache6.c.youtube.com%252Fvideoplayback ...);

2. Decode the url (remove the codes %2B,%25 etc), create a decoder with the codes: http://www.w3schools.com/tags/ref_urlencode.asp and use the function Uri.decode(url) to replace invalid escaped octets;

3. Use the code to download stream:

   URL u = null;
   InputStream is = null;  
   
   try {
       u = new URL(url);
       is = u.openStream(); 
       HttpURLConnection huc = (HttpURLConnection)u.openConnection(); //to know the size of video
       int size = huc.getContentLength();                 
   
       if(huc != null) {
           String fileName = "FILE.mp4";
           String storagePath = Environment.getExternalStorageDirectory().toString();
           File f = new File(storagePath,fileName);
   
           FileOutputStream fos = new FileOutputStream(f);
           byte[] buffer = new byte[1024];
           int len1 = 0;
           if(is != null) {
               while ((len1 = is.read(buffer)) > 0) {
                   fos.write(buffer,0, len1);  
               }
           }
           if(fos != null) {
               fos.close();
           }
       }                       
   } catch (MalformedURLException mue) {
       mue.printStackTrace();
   } catch (IOException ioe) {
       ioe.printStackTrace();
   } finally {
       try {               
           if(is != null) {
               is.close();
           }
       } catch (IOException ioe) {
           // just going to ignore this one
       }
   }
   

That's all, most of stuff you'll find on the web!!!

Here's a fairly clean solution that allows inheritance, using TypeScript 2.0. I didn't try this on an earlier version.

Bonus: the value can be any type!

export class Enum<T> {
  public constructor(public readonly value: T) {}
  public toString() {
    return this.value.toString();
  }
}

export class PrimaryColor extends Enum<string> {
  public static readonly Red = new Enum('#FF0000');
  public static readonly Green = new Enum('#00FF00');
  public static readonly Blue = new Enum('#0000FF');
}

export class Color extends PrimaryColor {
  public static readonly White = new Enum('#FFFFFF');
  public static readonly Black = new Enum('#000000');
}

// Usage:

console.log(PrimaryColor.Red);
// Output: Enum { value: '#FF0000' }
console.log(Color.Red); // inherited!
// Output: Enum { value: '#FF0000' }
console.log(Color.Red.value); // we have to call .value to get the value.
// Output: #FF0000
console.log(Color.Red.toString()); // toString() works too.
// Output: #FF0000

class Thing {
  color: Color;
}

let thing: Thing = {
  color: Color.Red,
};

switch (thing.color) {
  case Color.Red: // ...
  case Color.White: // ...
}

And there are a couple of other cases where if you catch an Error, you have to rethrow it. For example ThreadDeath should never be caught, it can cause big problem is you catch it in a contained environment (eg. an application server) :

An application should catch instances of this class only if it must clean up after being terminated asynchronously. If ThreadDeath is caught by a method, it is important that it be rethrown so that the thread actually dies.

Just in case someone is looking to this too. In .net core 3+ most of this is obsolete. The update way is:

public void Configure(
    IApplicationBuilder app,
    IWebHostEnvironment env,
    ILogger<Startup> logger)
{
    if (env.EnvironmentName == Environments.Development)
    {
        // logger.LogInformation("In Development environment");
    }
}

The package it-self is located under /data/app/com.company.appname-xxx.apk.

/data/app/com.company.appname is only a directory created to store files like native libs, cache, ecc...

You can retrieve the package installation path with the Context.getPackageCodePath() function call.

Sometimes an algorithm is easiest to understand top-down, starting with the overall structure and drilling down into the details.

You can do so without forward declarations:

def main():
  make_omelet()
  eat()

def make_omelet():
  break_eggs()
  whisk()
  fry()

def break_eggs():
  for egg in carton:
    break(egg)

# ...

main()

Use the below code in android.support.v4

FragmentTransaction ft1 = getFragmentManager().beginTransaction();
WebViewFragment w1 = new WebViewFragment();
w1.init(linkData.getLink());
ft1.addToBackStack(linkData.getName());
ft1.replace(R.id.listFragment, w1);
ft1.commit();

See jQuery's post function.

I would create a button, and set an onClickListener ($('#button').on('click', function(){});), and send the data in the function.

Also, see the preventDefault function, of jQuery!

There won't be any difference in terms of performance. Using java - cp we can specify the required classes and jar's in the classpath for running a java class file.

If it is a executable jar file . When java -jar command is used, jvm finds the class that it needs to run from /META-INF/MANIFEST.MF file inside the jar file.

The main benefit of using LDAP is that information for an entire organization can be consolidated into a central repository. For example, rather than managing user lists for each group within an organization, LDAP can be used as a central directory accessible from anywhere on the network. And because LDAP supports Secure Sockets Layer (SSL) and Transport Layer Security (TLS), sensitive data can be protected from prying eyes.

LDAP also supports a number of back-end databases in which to store directories. This allows administrators the flexibility to deploy the database best suited for the type of information the server is to disseminate. Because LDAP also has a well-defined client Application Programming Interface (API), the number of LDAP-enabled applications are numerous and increasing in quantity and quality.

The 'file' protocol is not a network protocol. Therefore file://192.168.1.57/~User/2ndFile.html simply does not make much sense.

Question is how you load the first file. Is that really done using a web server? Does not really sound like. If it is, then why not use the same protocol, most likely http? You cannot expect to simply switch the protocol and use two different protocols the same way...

I suspect the first file is really loaded using the apache server at all, but simply by opening the file? href="2ndFile.html" simply works because it uses a "relative url". This makes the browser use the same protocol and path as where he got the first (current) file from.

If state of a method is not supposed to be changed or its not going to use any instance variables.

You want to call method without instance.

If it only works on arguments provided to it.

Utility functions are good instance of static methods. i.e math.pow(), this function is not going to change the state for different values. So it is static.

The LogManager class determines which log4j config to use in a static block which runs when the class is loaded. There are three options intended for end-users:

1. If you specify log4j.defaultInitOverride to false, it will not configure log4j at all.

2. Specify the path to the configuration file manually yourself and override the classpath search. You can specify the location of the configuration file directly by using the following argument to java:

   -Dlog4j.configuration=<path to properties file>

   in your test runner configuration.

3. Allow log4j to scan the classpath for a log4j config file during your test. (the default)

See also the online documentation.

You can use the subscript operator

l[4] = -1

This should solve your problem, you should try to run the following below:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser 

Attach gdb to one of the httpd child processes and reload or continue working and wait for a crash and then look at the backtrace. Do something like this:

$ ps -ef|grep httpd
0     681     1   0 10:38pm ??         0:00.45 /Applications/MAMP/Library/bin/httpd -k start
501   690   681   0 10:38pm ??         0:00.02 /Applications/MAMP/Library/bin/httpd -k start

...

Now attach gdb to one of the child processes, in this case PID 690 (columns are UID, PID, PPID, ...)

$ sudo gdb
(gdb) attach 690
Attaching to process 690.
Reading symbols for shared libraries . done
Reading symbols for shared libraries ....................... done
0x9568ce29 in accept$NOCANCEL$UNIX2003 ()
(gdb) c
Continuing.

Wait for crash... then:

(gdb) backtrace

Or

(gdb) backtrace full

Should give you some clue what's going on. If you file a bug report you should include the backtrace.

If the crash is hard to reproduce it may be a good idea to configure Apache to only use one child processes for handling requests. The config is something like this:

StartServers 1
MinSpareServers 1
MaxSpareServers 1

If table_2 is empty, then try the following insert statement:

insert into table_2 (itemid,location1) 
select itemid,quantity from table_1 where locationid=1

If table_2 already contains the itemid values, then try this update statement:

update table_2 set location1=
(select quantity from table_1 where locationid=1 and table_1.itemid = table_2.itemid)

If you want a real timer you need to use the date object.

Calculate the difference.

Format your string.

window.onload=function(){
      var start=Date.now(),r=document.getElementById('r');
      (function f(){
      var diff=Date.now()-start,ns=(((3e5-diff)/1e3)>>0),m=(ns/60)>>0,s=ns-m*60;
      r.textContent="Registration closes in "+m+':'+((''+s).length>1?'':'0')+s;
      if(diff>3e5){
         start=Date.now()
      }
      setTimeout(f,1e3);
      })();
}

Example

Jsfiddle

not so precise timer

var time=5*60,r=document.getElementById('r'),tmp=time;

setInterval(function(){
    var c=tmp--,m=(c/60)>>0,s=(c-m*60)+'';
    r.textContent='Registration closes in '+m+':'+(s.length>1?'':'0')+s
    tmp!=0||(tmp=time);
},1000);

Let me add an example here:

I'm trying to build Alluxio on windows platform and got the same issue, it's because the pom.xml contains below step:

      <plugin>
        <artifactId>exec-maven-plugin</artifactId>
        <groupId>org.codehaus.mojo</groupId>
        <inherited>false</inherited>
        <executions>
          <execution>
            <id>Check that there are no Windows line endings</id>
            <phase>compile</phase>
            <goals>
              <goal>exec</goal>
            </goals>
            <configuration>
              <executable>${build.path}/style/check_no_windows_line_endings.sh</executable>
            </configuration>
          </execution>
        </executions>
      </plugin>

The .sh file is not executable on windows so the error throws.

Comment it out if you do want build Alluxio on windows.

Put a print function in the iframe and call it from the parent.

iframe:

function printMe() {
  window.print()
}

parent:

document.frame1.printMe()

if($('#testElement').is(':visible')){
    //what you want to do when is visible
}

Otherway using strings because why not

function isEven(__num){
    return String(__num/2).indexOf('.') === -1;
}

Due to PEP-0469 which renamed iteritems() to items() and PEP-3113 which removed Tuple parameter unpacking, in Python 3.x you should write Martijn Pieters? answer like this:

my_dictionary = dict(map(lambda item: (item[0], f(item[1])), my_dictionary.items()))

To display the item number on the repeater you can use the Container.ItemIndex property.

<asp:repeater id="rptRepeater" runat="server">
    <itemtemplate>
        Item <%# Container.ItemIndex + 1 %>| <%# Eval("Column1") %>
    </itemtemplate>
    <separatortemplate>
        <br />
    </separatortemplate>
</asp:repeater>

There's an extension that shows line endings. You can configure the color used, the characters that represent CRLF and LF and a boolean that turns it on and off.

drawInRect is certainly the way to go. Here's another little thing that will come in way useful when doing this. Usually the picture and the rectangle into which it is going to go don't conform. In that case drawInRect will stretch the picture. Here's a quick and cool way to make sure that the picture's aspect ration isn't changed, by reversing the transformation (which will be to fit the whole thing in):

//Picture and irect don't conform, so there'll be stretching, compensate
    float xf = Picture.size.width/irect.size.width;
    float yf = Picture.size.height/irect.size.height;
    float m = MIN(xf, yf);
    xf /= m;
    yf /= m;
    CGContextScaleCTM(ctx, xf, yf);

    [Picture drawInRect: irect];

A simpler solution exists. Set these attributes in your parent layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mainLayout"
    android:descendantFocusability="beforeDescendants"
    android:focusableInTouchMode="true" >

And now, when the activity starts this main layout will get focus by default.

Also, we can remove focus from child views at runtime (e.g., after finishing child editing) by giving the focus to the main layout again, like this:

findViewById(R.id.mainLayout).requestFocus();

Good comment from Guillaume Perrot:

android:descendantFocusability="beforeDescendants" seems to be the default (integer value is 0). It works just by adding android:focusableInTouchMode="true".

Really, we can see that the beforeDescendants set as default in the ViewGroup.initViewGroup() method (Android 2.2.2). But not equal to 0. ViewGroup.FOCUS_BEFORE_DESCENDANTS = 0x20000;

Thanks to Guillaume.

In my case, I was getting this error because my table had

varchar(50)

but I was injecting 67 character long string, which resulted in thi error. Changing it to

varchar(255)

fixed the problem.

Consider:

class Bike(object):
    def __init__(self, name, weight, cost):
        self.name = name
        self.weight = weight
        self.cost = cost

bikes = {
    # Bike designed for children"
    "Trike": Bike("Trike", 20, 100),      # <--
    # Bike designed for everyone"
    "Kruzer": Bike("Kruzer", 50, 165),    # <--
    }

# Markup of 20% on all sales
margin = .2
# Revenue minus cost after sale
for bike in bikes.values():
    profit = bike.cost * margin
    print(profit)

Output:

33.0
20.0

The difference is that in your bikes dictionary, you're initializing the values as lists [...]. Instead, it looks like the rest of your code wants Bike instances. So create Bike instances: Bike(...).

As for your error

AttributeError: 'list' object has no attribute 'cost'

this will occur when you try to call .cost on a list object. Pretty straightforward, but we can figure out what happened by looking at where you call .cost -- in this line:

profit = bike.cost * margin

This indicates that at least one bike (that is, a member of bikes.values() is a list). If you look at where you defined bikes you can see that the values were, in fact, lists. So this error makes sense.

But since your class has a cost attribute, it looked like you were trying to use Bike instances as values, so I made that little change:

[...] -> Bike(...)

and you're all set.
