I found the example RichardTheKiwi quite informative.

Just to offer another approach if you're looking for something like IF EXISTS (SELECT 1 ..) THEN ...

-- what I might write in MSSQL

IF EXISTS (SELECT 1 FROM Table WHERE FieldValue='')
BEGIN
    SELECT TableID FROM Table WHERE FieldValue=''
END
ELSE
BEGIN
    INSERT INTO TABLE(FieldValue) VALUES('')
    SELECT SCOPE_IDENTITY() AS TableID
END

-- rewritten for MySQL

IF (SELECT 1 = 1 FROM Table WHERE FieldValue='') THEN
BEGIN
    SELECT TableID FROM Table WHERE FieldValue='';
END;
ELSE
BEGIN
    INSERT INTO Table (FieldValue) VALUES('');
    SELECT LAST_INSERT_ID() AS TableID;
END;
END IF;

Basically, it depends on the TableModel that you are using for your JTable. If you are using the DefaultTableModel then you can do it in two ways:

DefaultTableModel dm = (DefaultTableModel)table.getModel();
dm.getDataVector().removeAllElements();
dm.fireTableDataChanged(); // notifies the JTable that the model has changed

or

DefaultTableModel dm = (DefaultTableModel)table.getModel();
while(dm.getRowCount() > 0)
{
    dm.removeRow(0);
}

See the JavaDoc of DefaultTableModel for more details

Use a struct to simulate the data members of a class. In terms of method scope you can simulate private methods by placing the private function prototypes in the .c file and the public functions in the .h file.

I found I needed to enable the SSL module in Apache (obviously prefix commands with sudo if you are not running as root):

a2enmod ssl

then restart Apache:

/etc/init.d/apache2 restart

More details of SSL in Apache for Ubuntu / Debian here.

You can use the BytesIO class to get a wrapper around strings that behaves like a file. The BytesIO object provides the same interface as a file, but saves the contents just in memory:

import io

with io.BytesIO() as output:
    image.save(output, format="GIF")
    contents = output.getvalue()

You have to explicitly specify the output format with the format parameter, otherwise PIL will raise an error when trying to automatically detect it.

If you loaded the image from a file it has a format parameter that contains the original file format, so in this case you can use format=image.format.

In old Python 2 versions before introduction of the io module you would have used the StringIO module instead.

(?<!1\.2\.3\.4).*Has exploded

You need to run this with -P to have negative lookbehind (Perl regular expression), so the command is:

grep -P '(?<!1\.2\.3\.4).*Has exploded' test.log

Try this. It uses negative lookbehind to ignore the line if it is preceeded by 1.2.3.4. Hope that helps!

Right Click the form you want to hide them on, choose Controls -> Properties.

In Properties, set

• Control Box -> False
• Minimize Box -> False
• Maximize Box -> False

You'll do this in the designer.

Here's the solution using jQuery:

    $().ready(function () {
        $(".formToValidate").validate();
        $(".checkBox").each(function (item) {
            $(this).rules("add", {
                required: true,
                minlength:3
            });
        });
    });

Here's a way of loading files sorta like C, etc.

from importlib.machinery import SourceFileLoader
import os

def LOAD (MODULE_PATH):
    if (MODULE_PATH [ 0 ] == "/"):
        FULL_PATH = MODULE_PATH;
    else:
        DIR_PATH = os.path.dirname (os.path.realpath (__file__))
        FULL_PATH = os.path.normpath (DIR_PATH + "/" + MODULE_PATH)

    return SourceFileLoader (FULL_PATH, FULL_PATH).load_module ()

Implementations Where:

Y = LOAD ("../Z.py")
A = LOAD ("./A.py")
D = LOAD ("./C/D.py")
A_ = LOAD ("/IMPORTS/A.py")

Y.DEF ();
A.DEF ();
D.DEF ();
A_.DEF ();

Where each of the files looks like this:

def DEF ():
    print ("A");

This happened on Windows 10 as well. I resolved it by creating an empty repositories.cfg file.

Setting

onPressed: null // disables click

and

onPressed: () => yourFunction() // enables click

Request.QueryString returns you a collection of Key/Value pairs representing the Query String. Not a String. Don't think that would cause a Object Reference error though. The reason your getting that is because as Mauro pointed out in the comments. It's QueryString and not Querystring.

Try:

Request.QueryString.ToString();

or

<%                                 
    string URL = Request.Url.AbsoluteUri 
    System.Net.WebClient wc = new System.Net.WebClient();
    string data = wc.DownloadString(URL);
    Response.Output.Write(data);
%>

Same as your code but Request.Url.AbsoluteUri will return the full path, including the query string.

For people get this post by search "update limit MySQL" trying to avoid turning off the safe update mode when facing update with the multiple-table syntax.

Since the offical document state

For the multiple-table syntax, UPDATE updates rows in each table named in table_references that satisfy the conditions. In this case, ORDER BY and LIMIT cannot be used.

https://stackoverflow.com/a/28316067/1278112
I think this answer is quite helpful. It gives an example

UPDATE customers SET countryCode = 'USA' WHERE country = 'USA'; -- which gives the error, you just write:

UPDATE customers SET countryCode = 'USA' WHERE (country = 'USA' AND customerNumber <> 0); -- Because customerNumber is a primary key you got no error 1175 any more.

What I want but would raise error code 1175.

UPDATE table1 t1
        INNER JOIN
    table2 t2 ON t1.name = t2.name 
SET 
    t1.column = t2.column
WHERE
    t1.name = t2.name;

The working edition

UPDATE table1 t1
        INNER JOIN
    table2 t2 ON t1.name = t2.name 
SET 
    t1.column = t2.column
WHERE
    (t1.name = t2.name and t1.prime_key !=0);

Which is really simple and elegant. Since the original answer doesn't get too much attention (votes), I post more explanation. Hope this can help others.

        $(document).ready(function(){
            $("body").css("-webkit-user-select","none");
            $("body").css("-moz-user-select","none");
            $("body").css("-ms-user-select","none");

Put the threads in a list and then use the Join method

 threads = []

 t = Thread(...)
 threads.append(t)

 ...repeat as often as necessary...

 # Start all threads
 for x in threads:
     x.start()

 # Wait for all of them to finish
 for x in threads:
     x.join()

You can use a redirect to that action :

redirect_to your_controller_action_url

Tkinter root windows have a method called after which can be used to schedule a function to be called after a given period of time. If that function itself calls after you've set up an automatically recurring event.

Here is a working example:

# for python 3.x use 'tkinter' rather than 'Tkinter'
import Tkinter as tk
import time

class App():
    def __init__(self):
        self.root = tk.Tk()
        self.label = tk.Label(text="")
        self.label.pack()
        self.update_clock()
        self.root.mainloop()

    def update_clock(self):
        now = time.strftime("%H:%M:%S")
        self.label.configure(text=now)
        self.root.after(1000, self.update_clock)

app=App()

Bear in mind that after doesn't guarantee the function will run exactly on time. It only schedules the job to be run after a given amount of time. It the app is busy there may be a delay before it is called since Tkinter is single-threaded. The delay is typically measured in microseconds.

script -c <PROGRAM> -f OUTPUT.txt

Key is -f. Quote from man script:

-f, --flush
     Flush output after each write.  This is nice for telecooperation: one person
     does 'mkfifo foo; script -f foo', and another can supervise real-time what is
     being done using 'cat foo'.

Run in background:

nohup script -c <PROGRAM> -f OUTPUT.txt

For replacing in place you can also do:

sed -i '' 's/\"//g' file.txt

or in Linux

sed -i 's/\"//g' file.txt

Maybe an old topic but if someone needs further help with this do the following for example (this puts the text in middle line of image if it has larger height then the text).

HTML:

<div class="row display-table">
    <div class="col-xs-12 col-sm-4 display-cell">
        img
    </div>
    <div class="col-xs-12 col-sm-8 display-cell">
        text
    </div>
</div>

CSS:

.display-table{
    display: table;
    table-layout: fixed;
}

.display-cell{
    display: table-cell;
    vertical-align: middle;
    float: none;
}

The important thing that I missed out on was "float: none;" since it got float left from bootstrap col attributes.

Cheers!

I often run into the same problem as yours, and I just wrote a piece of script:

function m() { # m means 'multi pattern grep'

    function _usage() {
    echo "usage: COMMAND [-inH] -p<pattern1> -p<pattern2> <filename>"
    echo "-i : ignore case"
    echo "-n : show line number"
    echo "-H : show filename"
    echo "-h : show header"
    echo "-p : specify pattern"
    }

    declare -a patterns
    # it is important to declare OPTIND as local
    local ignorecase_flag  filename linum header_flag colon result OPTIND

    while getopts "iHhnp:" opt; do
    case $opt in
        i)
        ignorecase_flag=true ;;
        H)
        filename="FILENAME," ;;
        n)
        linum="NR," ;;
        p)
        patterns+=( "$OPTARG" ) ;;
        h)
        header_flag=true ;;
        \?)
        _usage
        return ;;
    esac
    done

    if [[ -n $filename || -n $linum ]]; then
    colon="\":\","
    fi

    shift $(( $OPTIND - 1 ))

    if [[ $ignorecase_flag == true ]]; then
    for s in "${patterns[@]}"; do
            result+=" && s~/${s,,}/"
    done
    result=${result# && }
    result="{s=tolower(\$0)} $result"
    else
    for s in "${patterns[@]}"; do
            result="$result && /$s/"
    done
    result=${result# && }
    fi

    result+=" { print "$filename$linum$colon"\$0 }"

    if [[ ! -t 0 ]]; then       # pipe case
    cat - | awk "${result}"
    else
    for f in "$@"; do
        [[ $header_flag == true ]] && echo "########## $f ##########"
        awk "${result}" $f
    done
    fi
}

Usage:

echo "a b c" | m -p A 
echo "a b c" | m -i -p A # a b c

You can put it in .bashrc if you like.

Seems like the problem is with the date format.

 var d = "17-09-2013 10:08",
 dArr = d.split('-'),
 ts = new Date(dArr[1] + "-" + dArr[0] + "-" + dArr[2]).getTime(); // 1379392680000

pipdeptree is a command line utility for displaying the python packages installed in an virtualenv in form of a dependency tree. Just use it: https://github.com/naiquevin/pipdeptree

The guarantees the standard gives you go like this:

1 == sizeof(char) <= sizeof(short) <= sizeof (int) <= sizeof(long) <= sizeof(long long)

So it's perfectly valid for sizeof (int) and sizeof (long) to be equal, and many platforms choose to go with this approach. You will find some platforms where int is 32 bits, long is 64 bits, and long long is 128 bits, but it seems very common for sizeof (long) to be 4.

(Note that long long is recognized in C from C99 onwards, but was normally implemented as an extension in C++ prior to C++11.)

Just in case someone really needs a closure like that, it can be done in the following way:

var categoriesPerPage = [[Int]]()
var numPagesClosure: ()->Int {
    return {
        return self.categoriesPerPage.count
    }
}

There is pure CSS4 solution:

.selectable{
    -webkit-touch-callout: all; /* iOS Safari */
    -webkit-user-select: all; /* Safari */
    -khtml-user-select: all; /* Konqueror HTML */
    -moz-user-select: all; /* Firefox */
    -ms-user-select: all; /* Internet Explorer/Edge */
    user-select: all; /* Chrome and Opera */

}

user-select is a CSS Module Level 4 specification, that is currently a draft and non-standard CSS property, but browsers support it well — see #search=user-select.

.selectable{
    -webkit-touch-callout: all; /* iOS Safari */
    -webkit-user-select: all; /* Safari */
    -khtml-user-select: all; /* Konqueror HTML */
    -moz-user-select: all; /* Firefox */
    -ms-user-select: all; /* Internet Explorer/Edge */
    user-select: all; /* Chrome and Opera */

}

<div class="selectable">
click and all this will be selected
</div>

Read more on user-select here on MDN and play with it here in w3scools

1) Open your terminal and type

npm install -g http-server

2) Go to the root folder that you want to serve you files and type:

http-server ./

3) Read the output of the terminal, something kinda http://localhost:8080 will appear.

Everything on there will be allowed to be got. Example:

background: url('http://localhost:8080/waw.png');

<div className={['foo', condition && 'bar'].filter(Boolean).join(' ')} />

.filter(Boolean) removes "falsey" values from the array. Since class names must be strings, anything other than that would not be included in the new filtered array.

console.log(  ['foo', true  && 'bar'].filter(Boolean).join(' ')  )
console.log(  ['foo', false && 'bar'].filter(Boolean).join(' ')  )

Above written as a function:

const cx = (...list) => list.filter(Boolean).join(' ')

// usage:
<div className={cx('foo', condition && 'bar')} />

var cx = (...list) => list.filter(Boolean).join(' ')
console.log(  cx('foo', 1 && 'bar', 1 && 'baz')  )
console.log(  cx('foo', 0 && 'bar', 1 && 'baz')  )
console.log(  cx('foo', 0 && 'bar', 0 && 'baz')  )

You're opening a file, then passing the file pointer to a function that only wants a file name to open the file itself. You can simplify your call to;

void main(void)
{
  printf("LINES: %d\n",countlines("Test.txt"));
}

EDIT: You're changing the question around so it's very hard to answer; at first you got your change to main() wrong, you forgot that the first parameter is argc, so it crashed. Now you have the problem of;

if (fp == NULL);   // <-- note the extra semicolon that is the only thing 
                   //     that runs conditionally on the if 
  return 0;        // Always runs and returns 0

which will always return 0. Remove that extra semicolon, and you should get a reasonable count.

I have also faced the same problem and keep on getting stackOverflow exceptions, and I come with the following solution.

edt_amnt_sent.addTextChangedListener(new TextWatcher() {    
    @Override
    public void afterTextChanged(Editable s) {
        if (skipOnChange)
            return;

        skipOnChange = true;
        try {
            //method
        } catch (NumberFormatException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            skipOnChange = false;
        }
    }
});

edt_amnt_receive.addTextChangedListener(new TextWatcher() {

    @Override
    public void afterTextChanged(Editable s) {

        if (skipOnChange)
            return;

        skipOnChange = true;
        try {
            //method
        } catch (NumberFormatException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            skipOnChange = false;
        }
    }
});

declared initially boolean skipOnChange = false;

If you have control over the content of the iframe - that is, if it is merely loaded in a cross-origin setup such as on Amazon Mechanical Turk - you can circumvent this problem with the <body onload='my_func(my_arg)'> attribute for the inner html.

For example, for the inner html, use the this html parameter (yes - this is defined and it refers to the parent window of the inner body element):

<body onload='changeForm(this)'>

In the inner html :

    function changeForm(window) {
        console.log('inner window loaded: do whatever you want with the inner html');
        window.document.getElementById('mturk_form').style.display = 'none';
    </script>

You can commit in the current branch, checkout to another branch, and finally cherry-pick that commit (in lieu of merge).

You cannot use a constant literal for a default parameter for the same reason you cannot use one as a parameter to the function call. Reference values must have an address, constant references values need not (ie they can be r-values or constant literals).

int* foo (int& i )
{
   return &i;
}

foo(0); // compiler error.

const int* bar ( const int& i )
{
   return &i;
}

bar(0); // ok.

Ensure that you're default value has an address and you're fine.

int null_object = 0;

int Write(int &state = null_object, bool sequence = true)
{
   if( &state == &null_object )
   {
      // called with default paramter
      return sequence? 1: rand();
   }
   else
   {
      // called with user parameter
      state += sequence? 1: rand();
      return state;
   }
}

I've used this pattern a few times where I had a parameter that could be a variable or null. The regular approach is to have the user pass in a pointer this is case. They pass in a NULL pointer if they don't want you to fill in the value. I like to null object approach. It makes the callers life easier without terribly complicating the callee code.

for date-time comparison, you can use valueOf function of the moment which provides milliseconds of the date-time, which is best for comparison:

let date1 = moment('01-02-2020','DD-MM-YYYY').valueOf()_x000D_
let date2 = moment('11-11-2012','DD-MM-YYYY').valueOf()_x000D_
_x000D_
//     alert((date1 > date2 ? 'date1' : 'date2') + " is greater..."  )_x000D_
_x000D_
if (date1 > date2) {_x000D_
   alert("date1 is greater..." )_x000D_
} else {_x000D_
   alert("date2 is greater..." )_x000D_
}

This is a "roundabout" solution but you could use ipython

Start ipython notebook from terminal:

Unfortunately std::map::operator[] is a non-const member function, and you have a const reference.

You either need to change the signature of function or do:

MAP::const_iterator pos = map.find("string");
if (pos == map.end()) {
    //handle the error
} else {
    std::string value = pos->second;
    ...
}

operator[] handles the error by adding a default-constructed value to the map and returning a reference to it. This is no use when all you have is a const reference, so you will need to do something different.

You could ignore the possibility and write string value = map.find("string")->second;, if your program logic somehow guarantees that "string" is already a key. The obvious problem is that if you're wrong then you get undefined behavior.

Try this

IsBodyHtml = false,
BodyEncoding = Encoding.UTF8,
BodyTransferEncoding = System.Net.Mime.TransferEncoding.EightBit

I managed to get mine working after trying for one whole day!

Don't create any segue from Cancel or Done to other VC and only write this code your buttons @IBAction

@IBAction func cancel(sender: AnyObject) {
    dismiss(animated: false, completion: nil)
}

A very simple way to do so with IPython that worked for me in Visual Studio Code is to add the following:

{
    "key": "ctrl+space",
    "command": "jupyter.runallcells"
  }

to the keybindings.json that you can access by typing F1 and 'open keyboard shortcuts'.

If you install the SDK, the offline documentation can be found in $ANDROID_SDK/docs/.

I realize that this question is over 10 years old, but it appears to me that not only has the most obvious answer not been addressed, but that maybe its not really clear from the question a good understanding of what goes on under the covers. In addition, there are other questions about late binding and what that means with regards to delegates and lambdas (more on that later).

First to address the 800 lb elephant/gorilla in the room, when to choose event vs Action<T>/Func<T>:

• Use a lambda to execute one statement or method. Use event when you want more of a pub/sub model with multiple statements/lambdas/functions that will execute (this is a major difference right off the bat).
• Use a lambda when you want to compile statements/functions to expression trees. Use delegates/events when you want to participate in more traditional late binding such as used in reflection and COM interop.

As an example of an event, lets wire up a simple and 'standard' set of events using a small console application as follows:

public delegate void FireEvent(int num);

public delegate void FireNiceEvent(object sender, SomeStandardArgs args);

public class SomeStandardArgs : EventArgs
{
    public SomeStandardArgs(string id)
    {
        ID = id;
    }

    public string ID { get; set; }
}

class Program
{
    public static event FireEvent OnFireEvent;

    public static event FireNiceEvent OnFireNiceEvent;


    static void Main(string[] args)
    {
        OnFireEvent += SomeSimpleEvent1;
        OnFireEvent += SomeSimpleEvent2;

        OnFireNiceEvent += SomeStandardEvent1;
        OnFireNiceEvent += SomeStandardEvent2;


        Console.WriteLine("Firing events.....");
        OnFireEvent?.Invoke(3);
        OnFireNiceEvent?.Invoke(null, new SomeStandardArgs("Fred"));

        //Console.WriteLine($"{HeightSensorTypes.Keyence_IL030}:{(int)HeightSensorTypes.Keyence_IL030}");
        Console.ReadLine();
    }

    private static void SomeSimpleEvent1(int num)
    {
        Console.WriteLine($"{nameof(SomeSimpleEvent1)}:{num}");
    }
    private static void SomeSimpleEvent2(int num)
    {
        Console.WriteLine($"{nameof(SomeSimpleEvent2)}:{num}");
    }

    private static void SomeStandardEvent1(object sender, SomeStandardArgs args)
    {

        Console.WriteLine($"{nameof(SomeStandardEvent1)}:{args.ID}");
    }
    private static void SomeStandardEvent2(object sender, SomeStandardArgs args)
    {
        Console.WriteLine($"{nameof(SomeStandardEvent2)}:{args.ID}");
    }
}

The output will look as follows:

If you did the same with Action<int> or Action<object, SomeStandardArgs>, you would only see SomeSimpleEvent2 and SomeStandardEvent2.

So whats going on inside of event?

If we expand out FireNiceEvent, the compiler is actually generating the following (I have omitted some details with respect to thread synchronization that isn't relevant to this discussion):

   private EventHandler<SomeStandardArgs> _OnFireNiceEvent;

    public void add_OnFireNiceEvent(EventHandler<SomeStandardArgs> handler)
    {
        Delegate.Combine(_OnFireNiceEvent, handler);
    }

    public void remove_OnFireNiceEvent(EventHandler<SomeStandardArgs> handler)
    {
        Delegate.Remove(_OnFireNiceEvent, handler);
    }

    public event EventHandler<SomeStandardArgs> OnFireNiceEvent
    {
        add
        {
            add_OnFireNiceEvent(value)
        }
        remove
        {
            remove_OnFireNiceEvent(value)

        }
    }

The compiler generates a private delegate variable which is not visible to the class namespace in which it is generated. That delegate is what is used for subscription management and late binding participation, and the public facing interface is the familiar += and -= operators we have all come to know and love : )

You can customize the code for the add/remove handlers by changing the scope of the FireNiceEvent delegate to protected. This now allows developers to add custom hooks to the hooks, such as logging or security hooks. This really makes for some very powerful features that now allows for customized accessibility to subscription based on user roles, etc. Can you do that with lambdas? (Actually you can by custom compiling expression trees, but that's beyond the scope of this response).

To address a couple of points from some of the responses here:

• There really is no difference in the 'brittleness' between changing the args list in Action<T> and changing the properties in a class derived from EventArgs. Either will not only require a compile change, they will both change a public interface and will require versioning. No difference.

• With respect to which is an industry standard, that depends on where this is being used and why. Action<T> and such is often used in IoC and DI, and event is often used in message routing such as GUI and MQ type frameworks. Note that I said often, not always.

• Delegates have different lifetimes than lambdas. One also has to be aware of capture... not just with closure, but also with the notion of 'look what the cat dragged in'. This does affect memory footprint/lifetime as well as management a.k.a. leaks.

One more thing, something I referenced earlier... the notion of late binding. You will often see this when using framework like LINQ, regarding when a lambda becomes 'live'. That is very different than late binding of a delegate, which can happen more than once (i.e. the lambda is always there, but binding occurs on demand as often as is needed), as opposed to a lambda, which once it occurs, its done -- the magic is gone, and the method(s)/property(ies) will always bind. Something to keep in mind.

Where you want to get that connection is unclear. One possibility would be to get it from the underlying Hibernate Session used by the EntityManager. With JPA 1.0, you'll have to do something like this:

Session session = (Session)em.getDelegate();
Connection conn = session.connection();

Note that the getDelegate() is not portable, the result of this method is implementation specific: the above code works in JBoss, for GlassFish you'd have to adapt it - have a look at Be careful while using EntityManager.getDelegate().

In JPA 2.0, things are a bit better and you can do the following:

Connection conn = em.unwrap(Session.class).connection();

If you are running inside a container, you could also perform a lookup on the configured DataSource.

Let me propose this solution for you. So in your managed bean, do this

public String convertTime(long time){
    Date date = new Date(time);
    Format format = new SimpleDateFormat("yyyy MM dd HH:mm:ss");
    return format.format(date);
}

so in your JSF page, you can do this (assuming foo is the object that contain your time)

<h:dataTable value="#{myBean.convertTime(myBean.foo.time)}" />

If you have multiple pages that want to utilize this method, you can put this in an abstract class and have your managed bean extend this abstract class.

EDIT: Return time with TimeZone

unfortunately, I think SimpleDateFormat will always format the time in local time, so we can't use SimpleDateFormat anymore. So to display time in different TimeZone, we can do this

public String convertTimeWithTimeZome(long time){
    Calendar cal = Calendar.getInstance();
    cal.setTimeZone(TimeZone.getTimeZone("UTC"));
    cal.setTimeInMillis(time);
    return (cal.get(Calendar.YEAR) + " " + (cal.get(Calendar.MONTH) + 1) + " " 
            + cal.get(Calendar.DAY_OF_MONTH) + " " + cal.get(Calendar.HOUR_OF_DAY) + ":"
            + cal.get(Calendar.MINUTE));

}

A better solution is to utilize JodaTime. In my opinion, this API is much better than Calendar (lighter weight, faster and provide more functionality). Plus Calendar.Month of January is 0, that force developer to add 1 to the result, and you have to format the time yourself. Using JodaTime, you can fix all of that. Correct me if I am wrong, but I think JodaTime is incorporated in JDK7

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Working example

Each link has five different states: link, hover, active, focus and visited.

Link is the normal appearance, hover is when you mouse over, active is the state when it's clicked, focus follows active and visited is the state you end up when you unfocus the recently clicked link.

I'm guessing you want to achieve a different style on either focus or visited, then you can add the following CSS:

a { color: #00c; }
a:visited { #ccc; }
a:focus { #cc0; }

A recommended order in your CSS to not cause any trouble is the following:

a
a:visited { ... }
a:focus { ... }
a:hover { ... }
a:active { ... }

You can use your web browser's developer tools to force the states of the element like this (Chrome->Developer Tools/Inspect Element->Style->Filter :hov): Force state in Chrome Developer Tools

@Balasubramani M saved me here. Wanted to add one more to help people. This is the problem when you're gluing too many things together and being cavalier with versions. I updated a version of material-ui and need to change

import Card, {CardContent, CardMedia, CardActions } from "@material-ui/core/Card"; 

to this:

import Card from '@material-ui/core/Card';
import CardActions from '@material-ui/core/CardActions';
import CardContent from '@material-ui/core/CardContent';
import CardMedia from '@material-ui/core/CardMedia';

The ideal way is not to use ioutil.ReadAll, but rather use a decoder on the reader directly. Here's a nice function that gets a url and decodes its response onto a target structure.

var myClient = &http.Client{Timeout: 10 * time.Second}

func getJson(url string, target interface{}) error {
    r, err := myClient.Get(url)
    if err != nil {
        return err
    }
    defer r.Body.Close()

    return json.NewDecoder(r.Body).Decode(target)
}

Example use:

type Foo struct {
    Bar string
}

func main() {
    foo1 := new(Foo) // or &Foo{}
    getJson("http://example.com", foo1)
    println(foo1.Bar)

    // alternately:

    foo2 := Foo{}
    getJson("http://example.com", &foo2)
    println(foo2.Bar)
}

You should not be using the default *http.Client structure in production as this answer originally demonstrated! (Which is what http.Get/etc call to). The reason is that the default client has no timeout set; if the remote server is unresponsive, you're going to have a bad day.

$('#toptitle').html('New world');

or

@ComponentScan uses string array, like this:

@ComponentScan({"com.my.package.first","com.my.package.second"})

When you provide multiple package names in only one string, Spring interprets this as one package name, and thus can't find it.

Just create the header.php file, and where you want to use it do:

<?php
include('header.php');
?>

Same with the footer. You don't need php tags in these files if you just have html.

See more about include here:

http://php.net/manual/en/function.include.php

Use your mydate object and call getMonth() and getFullYear()

See this for more info: http://www.w3schools.com/jsref/jsref_obj_date.asp

Calling multiple functions on onClick for any element, you can create a wrapper function, something like this.

wrapperFunction = () => {
    //do something
    function 1();
    //do something
    function 2();
    //do something
    function 3();
}

These functions can be defined as a method on the parent class and then called from the wrapper function.

You may have the main element which will cause the onChange like this,

<a href='#' onClick={this.wrapperFunction}>Some Link</a>

Your action method considers model type asList<string>. But, in your view you are waiting for IEnumerable<Standings.Models.Teams>. You can solve this problem with changing the model in your view to List<string>.

But, the best approach would be to return IEnumerable<Standings.Models.Teams> as a model from your action method. Then you haven't to change model type in your view.

But, in my opinion your models are not correctly implemented. I suggest you to change it as:

public class Team
{
    public int Position { get; set; }
    public string HomeGround {get; set;}
    public string NickName {get; set;}
    public int Founded { get; set; }
    public string Name { get; set; }
}

Then you must change your action method as:

public ActionResult Index()
{
    var model = new List<Team>();

    model.Add(new Team { Name = "MU"});
    model.Add(new Team { Name = "Chelsea"});
    ...

    return View(model);
}

And, your view:

@model IEnumerable<Standings.Models.Team>

@{
     ViewBag.Title = "Standings";
}

@foreach (var item in Model)
{
    <div>
        @item.Name
        <hr />
    </div>
}

list(newdict) works in both Python 2 and Python 3, providing a simple list of the keys in newdict. keys() isn't necessary. (:

In opencv, cv.namedWindow() just creates a window object as you determine, but not resizing the original image. You can use cv2.resize(img, resolution) to solve the problem.

Here's what it displays, a 740 * 411 resolution image.

image = cv2.imread("740*411.jpg")
cv2.imshow("image", image)
cv2.waitKey(0)
cv2.destroyAllWindows()

Here, it displays a 100 * 200 resolution image after resizing. Remember the resolution parameter use column first then is row.

image = cv2.imread("740*411.jpg")
image = cv2.resize(image, (200, 100))
cv2.imshow("image", image)
cv2.waitKey(0)
cv2.destroyAllWindows()

Misspellings are irritating, aren't they? Check your spelling of empty, but then also try this:

#!/bin/bash -e

if [ -s diff.txt ]
then
        rm -f empty.txt
        touch full.txt
else
        rm -f full.txt
        touch empty.txt
fi

I like shell scripting a lot, but one disadvantage of it is that the shell cannot help you when you misspell, whereas a compiler like your C++ compiler can help you.

Notice incidentally that I have swapped the roles of empty.txt and full.txt, as @Matthias suggests.

Here is a simple solution for Java 8+:

public static <T> Collection<List<T>> prepareChunks(List<T> inputList, int chunkSize) {
    AtomicInteger counter = new AtomicInteger();
    return inputList.stream().collect(Collectors.groupingBy(it -> counter.getAndIncrement() / chunkSize)).values();
}

I prefer java's built in TimeUnit library

long seconds = TimeUnit.MINUTES.toSeconds(8);

You need to give a relative file path of <a href="../index.html">Home</a>

Alternately you can specify a link from the root of your site with <a href="/pages/en/index.html">Home</a>

.. and . have special meanings in file paths, .. means up one directory and . means current directory.

so <a href="index.html">Home</a> is the same as <a href="./index.html">Home</a>

You can get numpy version using Terminal or a Python code.

In a Terminal (bash) using Ubuntu:

pip list | grep numpy

In python 3.6.7, this code shows the numpy version:

import numpy
print (numpy.version.version)

If you insert this code in the file shownumpy.py, you can compile it:

python shownumpy.py

or

python3 shownumpy.py

I've got this output:

1.16.1

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();
       }
}

Here is a minified snippet, same code as Google Analytics and Facebook Pixel uses:

!function(e,s,t){(t=e.createElement(s)).async=!0,t.src="https://example.com/foo.js",(e=e.getElementsByTagName(s)[0]).parentNode.insertBefore(t,e)}(document,"script");

Replace https://example.com/foo.js with your script path.

You can ssh to your server and run this command

It worked for me..

I've opted for a quick Polyfill based on the above answers:

//# Polyfill
window.addEventListener = window.addEventListener || function (e, f) { window.attachEvent('on' + e, f); };

//# Standard usage
window.addEventListener("message", function(){ /*...*/ }, false);

Of course, like the answers above this doesn't ensure that window.attachEvent exists, which may or may not be an issue.

Since you want to append elements to existing list, you can use var List[Int] and then keep on adding elements to the same list. Note -> You have to make sure that you insert an element into existing list as follows:-

var l: List[int] = List() // creates an empty list

l = 3 :: l // adds 3 to the head of the list

l = 4 :: l // makes int 4 as the head of the list

// Now when you will print l, you will see two elements in the list ( 4, 3)

Must read Get your database under version control. Check the series of posts by K. Scott Allen.

When it comes to version control, the database is often a second or even third-class citizen. From what I've seen, teams that would never think of writing code without version control in a million years-- and rightly so-- can somehow be completely oblivious to the need for version control around the critical databases their applications rely on. I don't know how you can call yourself a software engineer and maintain a straight face when your database isn't under exactly the same rigorous level of source control as the rest of your code. Don't let this happen to you. Get your database under version control.

You can just write multiple email address to whom you want to send and pass it as the first argument. Example:-

TL;DR

Make sure you have downloaded the latest 'Command Line Tools' package and run this from a terminal (command line):

open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

^{Extracting a semi-coherent answer from rather extensive comments…}

Preamble

Very often, xcode-select --install has been the correct solution, but it does not seem to help this time. Have you tried running the main Xcode GUI interface? It may install some extra software for you and clean up. I did that after installing Xcode 10.0, but a week or more ago, long before upgrading to Mojave.

I observe that if your GCC is installed in /usr/local/bin, you probably aren't using the GCC from Xcode; that's normally installed in /usr/bin.

I too have updated to macOS 10.14 Mojave and Xcode 10.0. However, both the system /usr/bin/gcc and system /usr/bin/clang are working for me (Apple LLVM version 10.0.0 (clang-1000.11.45.2) Target: x86_64-apple-darwin18.0.0 for both.) I have a problem with my home-built GCC 8.2.0 not finding headers in /usr/include, which is parallel to your problem with /usr/local/bin/gcc not finding headers either.

I've done a bit of comparison, and my Mojave machine has no /usr/include at all, yet /usr/bin/clang is able to compile OK. A header (_stdio.h, with leading underscore) was in my old /usr/include; it is missing now (hence my problem with GCC 8.2.0). I ran xcode-select --install and it said "xcode-select: note: install requested for command line developer tools" and then ran a GUI installer which showed me a licence which I agreed to, and it downloaded and installed the command line tools — or so it claimed.

I then ran Xcode GUI (command-space, Xcode, return) and it said it needed to install some more software, but still no /usr/include. But I can compile with /usr/bin/clang and /usr/bin/gcc — and the -v option suggests they're using

InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Working solution

Then Maxxx noted:

I've found a way. If we are using Xcode 10, you will notice that if you navigate to the /usr in the Finder, you will not see a folder called 'include' any more, which is why the terminal complains of the absence of the header files which is contained inside the 'include' folder. In the Xcode 10.0 Release Notes, it says there is a package:

/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg 

and you should install that package to have the /usr/include folder installed. Then you should be good to go.

When all else fails, read the manual or, in this case, the release notes. I'm not dreadfully surprised to find Apple wanting to turn their backs on their Unix heritage, but I am disappointed. If they're careful, they could drive me away. Thank you for the information.

Having installed the package using the following command at the command line, I have /usr/include again, and my GCC 8.2.0 works once more.

open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

Downloading Command Line Tools

As Vesal points out in a valuable comment, you need to download the Command Line Tools package for Xcode 10.1 on Mojave 10.14, and you can do so from:

• https://developer.apple.com/download/more/

You need to login with an Apple ID to be able to get the download. When you've done the download, install the Command Line Tools package. Then install the headers as described in the section 'Working Solution'.

This worked for me on Mojave 10.14.1. I must have downloaded this before, but I'd forgotten by the time I was answering this question.

Upgrade to Mojave 10.14.4 and Xcode 10.2

On or about 2019-05-17, I updated to Mojave 10.14.4, and the Xcode 10.2 command line tools were also upgraded (or Xcode 10.1 command line tools were upgraded to 10.2). The open command shown above fixed the missing headers. There may still be adventures to come with upgrading the main Xcode to 10.2 and then re-reinstalling the command line tools and the headers package.

Upgrade to Xcode 10.3 (for Mojave 10.14.6)

On 2019-07-22, I got notice via the App Store that the upgrade to Xcode 10.3 is available and that it includes SDKs for iOS 12.4, tvOS 12.4, watchOS 5.3 and macOS Mojave 10.14.6. I installed it one of my 10.14.5 machines, and ran it, and installed extra components as it suggested, and it seems to have left /usr/include intact.

Later the same day, I discovered that macOS Mojave 10.14.6 was available too (System Preferences ? Software Update), along with a Command Line Utilities package IIRC (it was downloaded and installed automatically). Installing the o/s update did, once more, wipe out /usr/include, but the open command at the top of the answer reinstated it again. The date I had on the file for the open command was 2019-07-15.

Upgrade to XCode 11.0 (for Catalina 10.15)

The upgrade to XCode 11.0 ("includes Swift 5.1 and SDKs for iOS 13, tvOS 13, watchOS 6 and macOS Catalina 10.15") was released 2019-09-21. I was notified of 'updates available', and downloaded and installed it onto machines running macOS Mojave 10.14.6 via the App Store app (updates tab) without problems, and without having to futz with /usr/include. Immediately after installation (before having run the application itself), I tried a recompilation and was told:

Agreeing to the Xcode/iOS license requires admin privileges, please run “sudo xcodebuild -license” and then retry this command.

Running that (sudo xcodebuild -license) allowed me to run the compiler. Since then, I've run the application to install extra components it needs; still no problem. It remains to be seen what happens when I upgrade to Catalina itself — but my macOS Mojave 10.14.6 machines are both OK at the moment (2019-09-24).

You can. Here is an example.

redis 127.0.0.1:6379> hset key f1 1
(integer) 1
redis 127.0.0.1:6379> hset key f2 2
(integer) 1
redis 127.0.0.1:6379> hvals key
1) "1"
2) "1"
3) "2"
redis 127.0.0.1:6379> expire key 10
(integer) 1
redis 127.0.0.1:6379> hvals key
1) "1"
2) "1"
3) "2"
redis 127.0.0.1:6379> hvals key
1) "1"
2) "1"
3) "2"
redis 127.0.0.1:6379> hvals key

Use EXPIRE or EXPIREAT command.

If you want to expire specific keys in the hash older then 1 month. This is not possible. Redis expire command is for all keys in the hash. If you set daily hash key, you can set a keys time to live.

hset key-20140325 f1 1
expire key-20140325 100
hset key-20140325 f1 2

Give a different alias

SELECT  Convert(varchar,A.InsertDate,103) as converted_Tran_Date from table as A
order by A.InsertDate 

So are you trying to grep through older versions of the code looking to see where something last exists?

If I were doing this, I would probably use git bisect. Using bisect, you can specify a known good version, a known bad version, and a simple script that does a check to see if the version is good or bad (in this case a grep to see if the code you are looking for is present). Running this will find when the code was removed.

This one didn't seem too bad.

>>> dic0 = {'dic0':0}
>>> dic1 = {'dic1':1}
>>> ndic = dict(dic0.items() + dic1.items())
>>> ndic
{'dic0': 0, 'dic1': 1}
>>>

Already answered... But if you need a featured, re-usable timer that also supports multiple tasks on different intervals, you can use my TaskTimer (for Node and browser).

// Timer with 1000ms (1 second) base interval resolution.
const timer = new TaskTimer(1000);

// Add task(s) based on tick intervals.
timer.add({
    id: 'job1',         // unique id of the task
    tickInterval: 5,    // run every 5 ticks (5 x interval = 5000 ms)
    totalRuns: 10,      // run 10 times only. (omit for unlimited times)
    callback(task) {
        // code to be executed on each run
        console.log(task.name + ' task has run ' + task.currentRuns + ' times.');
        // stop the timer anytime you like
        if (someCondition()) timer.stop();
        // or simply remove this task if you have others
        if (someCondition()) timer.remove(task.id);
    }
});

// Start the timer
timer.start();

In your case, when users click for disturbing the data-refresh; you can also call timer.pause() then timer.resume() if they need to re-enable.

The stack pointer holds the address to the top of the stack. A stack allows functions to pass arguments stored on the stack to each other, and to create scoped variables. Scope in this context means that the variable is popped of the stack when the stack frame is gone, and/or when the function returns. Without a stack, you would need to use explicit memory addresses for everything. That would make it impossible (or at least severely difficult) to design high-level programming languages for the architecture. Also, each CPU mode usually have its own banked stack pointer. So when exceptions occur (interrupts for example), the exception handler routine can use its own stack without corrupting the user process.

JLabel label = new JLabel("Hello World");
label.setFont(new Font("Calibri", Font.BOLD, 20));

This is an old thread, but as it still gets viewed and recently active "26" days ago as of this post, here is a quick solution.

There is no .env file initially, you must duplicate .env.example as .env.

In windows, you can open a command prompt aka the CLI and paste the exact code below while inside the root directory of the project. Must include the ( at the start line without space.

(
echo APP_NAME=Laravel
echo APP_ENV=local
echo APP_KEY=
echo APP_DEBUG=true
echo APP_URL=http://localhost
echo.
echo LOG_CHANNEL=stack
echo.
echo DB_CONNECTION=mysql
echo DB_HOST=127.0.0.1
echo DB_PORT=3306
echo DB_DATABASE=homestead
echo DB_USERNAME=homestead
echo DB_PASSWORD=secret
echo.
echo BROADCAST_DRIVER=log
echo CACHE_DRIVER=file
echo SESSION_DRIVER=file
echo SESSION_LIFETIME=120
echo QUEUE_DRIVER=sync
echo.
echo REDIS_HOST=127.0.0.1
echo REDIS_PASSWORD=null
echo REDIS_PORT=6379
echo.
echo MAIL_DRIVER=smtp
echo MAIL_HOST=smtp.mailtrap.io
echo MAIL_PORT=2525
echo MAIL_USERNAME=null
echo MAIL_PASSWORD=null
echo MAIL_ENCRYPTION=null
echo.
echo PUSHER_APP_ID=
echo PUSHER_APP_KEY=
echo PUSHER_APP_SECRET=
echo PUSHER_APP_CLUSTER=mt1
echo.
echo MIX_PUSHER_APP_KEY="${PUSHER_APP_KEY}"
echo MIX_PUSHER_APP_CLUSTER="${PUSHER_APP_CLUSTER}"
)>".env"

Just press enter to exit the prompt and you should have the .env file with the default settings created in the same directory you typed above CLI command.

Hope this helps.

The answers using grep are wrong. You need to add an -x option to match the entire line otherwise lines like #text to add will still match when looking to add exactly text to add.

So the correct solution is something like:

grep -qxF 'include "/configs/projectname.conf"' foo.bar || echo 'include "/configs/projectname.conf"' >> foo.bar

I raise an event in the the form setting the value and subscribe to that event in the form(s) that need to deal with the value change.

I think it would be better to write like this.

git rm --cache *//UserInterfaceState.xcuserstate**

update mytable set title=trim(replace(REPLACE(title,CHAR(13),''),CHAR(10),''));

Above is working for fine.

Delay function to call up on every keyup. jQuery 1.7.1 or up required

jQuery.fn.keyupDelay = function( cb, delay ){
  if(delay == null){
    delay = 400;
  }
  var timer = 0;
  return $(this).on('keyup',function(){
    clearTimeout(timer);
    timer = setTimeout( cb , delay );
  });
}

Usage: $('#searchBox').keyupDelay( cb );

Yes, if you use the SQL Server Agent.

Open your Enterprise Manager, and go to the Management folder under the SQL Server instance you are interested in. There you will see the SQL Server Agent, and underneath that you will see a Jobs section.

Here you can create a new job and you will see a list of steps you will need to create. When you create a new step, you can specify the step to actually run a stored procedure (type TSQL Script). Choose the database, and then for the command section put in something like:

exec MyStoredProcedure

That's the overview, post back here if you need any further advice.

[I actually thought I might get in first on this one, boy was I wrong :)]

The solution above not working for the latest version on PostgreSQL. I found this way to convert epoch time being stored in number and int column type is on PostgreSQL 13:

SELECT TIMESTAMP 'epoch' + (<table>.field::int) * INTERVAL '1 second' as started_on from <table>;

For more detail explanation, you can see here https://www.yodiw.com/convert-epoch-time-to-timestamp-in-postgresql/#more-214

install below libraries

var express = require(‘express’);
var fs = require(‘fs’);
var mongoose = require(‘mongoose’);
var Schema = mongoose.Schema;
var multer = require('multer');

connect ur mongo db :

mongoose.connect(‘url_here’);

Define database Schema

var Item = new ItemSchema({ 
    img: { 
       data: Buffer, 
       contentType: String 
    }
 }
);
var Item = mongoose.model('Clothes',ItemSchema);

using the middleware Multer to upload the photo on the server side.

app.use(multer({ dest: ‘./uploads/’,
  rename: function (fieldname, filename) {
    return filename;
  },
}));

post req to our db

app.post(‘/api/photo’,function(req,res){
  var newItem = new Item();
  newItem.img.data = fs.readFileSync(req.files.userPhoto.path)
  newItem.img.contentType = ‘image/png’;
  newItem.save();
});

For those like me who want to unload all modules (when running in the Python interpreter under Emacs):

   for mod in sys.modules.values():
      reload(mod)

More information is in Reloading Python modules.

The jar file is missing. You can download the jar file and add it as external libraries in your project . You can download this from

http://www.findjar.com/jar/com/googlecode/json-simple/json-simple/1.1/json-simple-1.1.jar.html

Yes, it can be done.
It is based on the new html5 "download" attribute of anchor tags.
The flow should be something like this :

1. load the image
2. draw the image into a canvas with the crop boundaries specified
3. get the image data from the canvas and make it a href attribute for an anchor tag in the dom
4. add the download attribute (download="desired-file-name") to that a element That's it. all the user has to do is click your "download link" and the image will be downloaded to his pc.

I'll come back with a demo when I get the chance.

Update
Here's the live demo as I promised. It takes the jsfiddle logo and crops 5px of each margin.
The code looks like this :

var img = new Image();
img.onload = function(){
    var cropMarginWidth = 5,
        canvas = $('<canvas/>')
                    .attr({
                         width: img.width - 2 * cropMarginWidth,
                         height: img.height - 2 * cropMarginWidth
                     })
                    .hide()
                    .appendTo('body'),
        ctx = canvas.get(0).getContext('2d'),
        a = $('<a download="cropped-image" title="click to download the image" />'),
        cropCoords = {
            topLeft : {
                x : cropMarginWidth,
                y : cropMarginWidth 
            },
            bottomRight :{
                x : img.width - cropMarginWidth,
                y : img.height - cropMarginWidth
            }
        };

    ctx.drawImage(img, cropCoords.topLeft.x, cropCoords.topLeft.y, cropCoords.bottomRight.x, cropCoords.bottomRight.y, 0, 0, img.width, img.height);
    var base64ImageData = canvas.get(0).toDataURL();


    a
        .attr('href', base64ImageData)
        .text('cropped image')
        .appendTo('body');

    a
        .clone()
        .attr('href', img.src)
        .text('original image')
        .attr('download','original-image')
        .appendTo('body');

    canvas.remove();
}
img.src = 'some-image-src';

Update II
Forgot to mention : of course there is a downside :(.
Because of the same-origin policy that is applied to images too, if you want to access an image's data (through the canvas method toDataUrl).
So you would still need a server-side proxy that would serve your image as if it were hosted on your domain.

Update III Although I can't provide a live demo for this (for security reasons), here is a php sample code that solves the same-origin policy :

file proxy.php :

$imgData = getimagesize($_GET['img']);
header("Content-type: " . $imgData['mime']);
echo file_get_contents($_GET['img']);  

This way, instead of loading the external image direct from it's origin :

img.src = 'http://some-domain.com/imagefile.png';

You can load it through your proxy :

img.src = 'proxy.php?img=' + encodeURIComponent('http://some-domain.com/imagefile.png');  

And here's a sample php code for saving the image data (base64) into an actual image :

file save-image.php :

$data = preg_replace('/data:image\/(png|jpg|jpeg|gif|bmp);base64/','',$_POST['data']);
$data = base64_decode($data);
$img = imagecreatefromstring($data);

$path = 'path-to-saved-images/';
// generate random name
$name  = substr(md5(time()),10);
$ext = 'png';
$imageName = $path.$name.'.'.$ext;

// write the image to disk
imagepng($img,  $imageName);
imagedestroy($img);
// return the image path
echo $imageName;

All you have to do then is post the image data to this file and it will save the image to disc and return you the existing image filename.

Of course all this might feel a bit complicated, but I wanted to show you that what you're trying to achieve is possible.

Try this:

-1 * numeric_limits<double>::max()

Reference: numeric_limits

This class is specialized for each of the fundamental types, with its members returning or set to the different values that define the properties that type has in the specific platform in which it compiles.

You could try argmax like this:

dataframe['name'].value_counts().argmax() Out[13]: 'alex'

The value_counts will return a count object of pandas.core.series.Series and argmax could be used to achieve the key of max values.

If you need to extend ActionBarActivity you need on your style.xml:

<!-- Base application theme. -->
<style name="AppTheme" parent="AppTheme.Base"/>

<style name="AppTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->

If you set as main theme of your application as android:Theme.Material.Light instead of AppTheme.Base then you’ll get an “IllegalStateException:You need to use a Theme.AppCompat theme (or descendant) with this activity” error.

Disclaimer: This answer does not conform to the constraints of the question:

I don't want to have to create a new byte array in the heap memory just to do that.

(Honestly, I feel my answer is worthy of deletion. The answer by @unique72 is correct. Imma let this edit sit for a bit and then I shall delete this answer.)

I don't know of a way to do this directly with arrays without additional heap allocation, but the other answers using a sub-list wrapper have additional allocation for the wrapper only – but not the array – which would be useful in the case of a large array.

That said, if one is looking for brevity, the utility method Arrays.copyOfRange() was introduced in Java 6 (late 2006?):

byte [] a = new byte [] {0, 1, 2, 3, 4, 5, 6, 7};

// get a[4], a[5]

byte [] subArray = Arrays.copyOfRange(a, 4, 6);

I agree with what Joachim Sauer said, not possible to know (the variable type! not value type!) unless your variable is a class attribute (and you would have to retrieve class fields, get the right field by name...)

Actually for me it's totally impossible that any a.xxx().yyy() method give you the right answer since the answer would be different on the exact same object, according to the context in which you call this method...

As teehoo said, if you know at compile a defined list of types to test you can use instanceof but you will also get subclasses returning true...

One possible solution would also be to inspire yourself from the implementation of java.lang.reflect.Field and create your own Field class, and then declare all your local variables as this custom Field implementation... but you'd better find another solution, i really wonder why you need the variable type, and not just the value type?

Aforementioned answers are great, just putting few points I see might be helpful:

• Func is built-in delegate type

• Func delegate type must return a value. Use Action delegate if no return type needed.

• Func delegate type can have zero to 16 input parameters.

• Func delegate does not allow ref and out parameters.

• Func delegate type can be used with an anonymous method or lambda expression.

  Func<int, int, int> Sum = (x, y) => x + y;

You can use the rpad and lpad functions to pad numbers to the right or to the left, respectively. Note that this does not work directly on numbers, so you'll have to use ::char or ::text to cast them:

SELECT RPAD(numcol::text, 3, '0'), -- Zero-pads to the right up to the length of 3
       LPAD(numcol::text, 3, '0'), -- Zero-pads to the left up to the length of 3
FROM   my_table

If the class uses as a parameterized type, it can declare an array of type T[], but it cannot directly instantiate such an array. Instead, a common approach is to instantiate an array of type Object[], and then make a narrowing cast to type T[], as shown in the following:

  public class Portfolio<T> {
  T[] data;
 public Portfolio(int capacity) {
   data = new T[capacity];                 // illegal; compiler error
   data = (T[]) new Object[capacity];      // legal, but compiler warning
 }
 public T get(int index) { return data[index]; }
 public void set(int index, T element) { data[index] = element; }
}

Import the Support Libraries, In your project's build.gradle file, add the following lines in the project's dependencies:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    compile 'com.android.support:design:22.2.0'
    compile 'com.android.support:appcompat-v7:22.2.0'
}

Use following TextInputLayout in your UI Layout:

<android.support.design.widget.TextInputLayout
    android:id="@+id/usernameWrapper"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <EditText
        android:id="@+id/username"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textEmailAddress"
        android:hint="Username"/>

</android.support.design.widget.TextInputLayout>

Than, call setHint on TextInputLayout just after setContentView call because, to animate the floating label, you just need to set a hint, using the setHint method.

final TextInputLayout usernameWrapper = (TextInputLayout) findViewById(R.id.usernameWrapper);
usernameWrapper.setHint("Username");

This is an old question but it has a lot of views so I think that is important to update it.

ECMAScript 6 brought the function Math.sign(), which returns the sign of a number (1 if it's positive, -1 if it's negative) or NaN if it is not a number. Reference

You could use it as:

var number = 1;

if(Math.sign(number) === 1){
    alert("I'm positive");
}else if(Math.sign(number) === -1){
    alert("I'm negative");
}else{
    alert("I'm not a number");
}

1. File -> Import -> Existing Project into Workspace
2. Browse for that directory.

Alternative: Check out the code in SVN to some folder

1. Create a new folder in windows
2. In eclipse File -> switchWorkspace -> newFolderName
3. close the welcome window in eclipse
4. In eclipse File -> Import -> Existing project into workspce-> select root dir -> browse and show the svn checkout folder

For IP address- adb shell ifconfig under wlan0 Link encap:UNSPEC you will have your ip address written

If you only want to change form's action, I prefer changing action on-form-submit, rather than on-input-change. It fires only once.

$('#search-form').submit(function(){
  var formAction = $("#selectsearch").val() == "people" ? "user" : "content";
  $("#search-form").attr("action", "/search/" + formAction);
}); 

Setting the timeout in the web.xml is the correct way to set the timeout.

C:\Users\*********\AppData\Local\Android\Sdk

Check whether the USERNAME is correct, for me a new USERNAME got created with my proxy extension.

The problem of using Application.Restart() is, that it starts a new process but the "old" one is still remaining. Therefor I decided to Kill the old process by using the following code snippet:

            if(Condition){
            Application.Restart();
            Process.GetCurrentProcess().Kill();
            }

And it works proper good. In my case MATLAB and a C# Application are sharing the same SQLite database. If MATLAB is using the database, the Form-App should restart (+Countdown) again, until MATLAB reset its busy bit in the database. (Just for side information)

You can just go for String replace method.-

line1 = line1.replace("\"", "");

Here's my little 2 cents, for what it's worth ;)

def indexLines(filename, lines=[2,4,6,8,10,12,3,5,7,1]):
    fp   = open(filename, "r")
    src  = fp.readlines()
    data = [(index, line) for index, line in enumerate(src) if index in lines]
    fp.close()
    return data


# Usage below
filename = "C:\\Your\\Path\\And\\Filename.txt"
for line in indexLines(filename): # using default list, specify your own list of lines otherwise
    print "Line: %s\nData: %s\n" % (line[0], line[1])

What type of sql database are using (MSSQL, Oracle etc)? I believe what you have written is correct.

You could also write the first query like this:

SELECT s.sid, s.name
FROM Supplier s
WHERE (SELECT COUNT(DISTINCT pr.jid)
       FROM Supplies su, Projects pr
       WHERE su.sid = s.sid 
           AND pr.jid = su.jid) >= 2

It's a little more readable, and less mind-bending than trying to do it with GROUP BY. Performance may differ though.

Based on vedval i have this solution.

public boolean checkForPermission(final String[] permissions, final int permRequestCode) {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {

    for (int i = 0; i < permissions.length; i++) {
        final String perm = permissions[i];
        if (ContextCompat.checkSelfPermission(this, permissions[i]) != PackageManager.PERMISSION_GRANTED) {
            if (shouldShowRequestPermissionRationale(permissions[i])) {
                Snackbar.make(phrase, R.string.permission_location, Snackbar.LENGTH_INDEFINITE)

                        });
            } else {

            }
        }
    }

    if (permissionsNeeded.size() > 0) {
        // go ahead and request permissions
        requestPermissions(permissionsNeeded.toArray(new String[permissionsNeeded.size()]), permRequestCode);
        return false;
    } else {
        // no permission need to be asked so all good...we have them all.
        return true;
    }

}

you really should try to use jQuery in a separate file, not inline. Here is what you need:

<a class="notificationClose "><img src="close.png"/></a>

And then this at the bottom of your page in <script> tags at the very least or in a external JavaScript file.

$(".notificationClose").click(function() {
    $("#notification").fadeOut("normal", function() {
        $(this).remove();
    });
});

Starting with SQL Server 2012, you could use TRY_PARSE or TRY_CONVERT.

SELECT TRY_PARSE(MyVarcharCol as int)

SELECT TRY_CONVERT(int, MyVarcharCol)

Pure JS - no string middlestep (no atob)

I write following function which convert base64 in direct way (without conversion to string at the middlestep). IDEA

• get 4 base64 characters chunk
• find index of each character in base64 alphabet
• convert index to 6-bit number (binary string)
• join four 6 bit numbers which gives 24-bit numer (stored as binary string)
• split 24-bit string to three 8-bit and covert each to number and store them in output array
• corner case: if input base64 string ends with one/two = char, remove one/two numbers from output array

Below solution allows to process large input base64 strings. Similar function for convert bytes to base64 without btoa is HERE

function base64ToBytesArr(str) {
  const abc = [..."ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"]; // base64 alphabet
  let result = [];

  for(let i=0; i<str.length/4; i++) {
    let chunk = [...str.slice(4*i,4*i+4)]
    let bin = chunk.map(x=> abc.indexOf(x).toString(2).padStart(6,0)).join(''); 
    let bytes = bin.match(/.{1,8}/g).map(x=> +('0b'+x));
    result.push(...bytes.slice(0,3 - (str[4*i+2]=="=") - (str[4*i+3]=="=")));
  }
  return result;
}


// --------
// TEST
// --------


let test = "Alice's Adventure in Wonderland.";  

console.log('test string:', test.length, test);
let b64_btoa = btoa(test);
console.log('encoded string:', b64_btoa);

let decodedBytes = base64ToBytesArr(b64_btoa); // decode base64 to array of bytes

Inverse of a matrix using python and numpy:

>>> import numpy as np
>>> b = np.array([[2,3],[4,5]])
>>> np.linalg.inv(b)
array([[-2.5,  1.5],
       [ 2. , -1. ]])

Not all matrices can be inverted. For example singular matrices are not Invertable:

>>> import numpy as np
>>> b = np.array([[2,3],[4,6]])
>>> np.linalg.inv(b)

LinAlgError: Singular matrix

Solution to singular matrix problem:

try-catch the Singular Matrix exception and keep going until you find a transform that meets your prior criteria AND is also invertable.

Intuition for why matrix inversion can't always be done; like in singular matrices:

Imagine an old overhead film projector that shines a bright light through film onto a white wall. The pixels in the film are projected to the pixels on the wall.

If I stop the film projection on a single frame, you will see the pixels of the film on the wall and I ask you to regenerate the film based on what you see. That's easy, you say, just take the inverse of the matrix that performed the projection. An Inverse of a matrix is the reversal of the projection.

Now imagine if the projector was corrupted, and I put a distorted lens in front of the film. Now multiple pixels are projected to the same spot on the wall. I asked you again to "undo this operation with the matrix inverse". You say: "I can't because you destroyed information with the lens distortion, I can't get back to where we were, because the matrix is either Singular or Degenerate."

A matrix that can be used to transform some data into other data is invertable only if the process can be reversed with no loss of information. If your matrix can't be inverted, perhaps you are defining your projection using a guess-and-check methodology rather than using a process that guarantees a non-corrupting transform.

If you're using a heuristic or anything less than perfect mathematical precision, then you'll have to define another process to manage and quarantine distortions so that programming by Brownian motion can resume.

Use DateTime

$datetime = new DateTime('tomorrow');
echo $datetime->format('Y-m-d H:i:s');

Or:

$datetime = new DateTime('2013-01-22');
$datetime->modify('+1 day');
echo $datetime->format('Y-m-d H:i:s');

Or:

$datetime = new DateTime('2013-01-22');
$datetime->add(new DateInterval("P1D"));
echo $datetime->format('Y-m-d H:i:s');

Or in PHP 5.4+:

echo (new DateTime('2013-01-22'))->add(new DateInterval("P1D"))
                                 ->format('Y-m-d H:i:s');

You could try:

$('input.class').removeAttr('value');
$('#inputID').removeAttr('value');

i got this to work. you just need to change the variables

$query ="SELECT `column_name` FROM `information_schema`.`columns` WHERE `table_schema`='" . $_SESSION['db'] . "' AND `table_name`='" . $table . "' ";
$stmt = $dbh->prepare($query);
$stmt->execute(); 
$columns = $stmt->fetchAll(PDO::FETCH_ASSOC);       

$query="SELECT name FROM `" . $database . "`.`" . $table . "` WHERE ( ";
foreach ( $columns as $column ) {
    $query .=" CONVERT( `" . $column['column_name'] . "` USING utf8 ) LIKE '%" . $search . "%' OR ";
}
$query = substr($query, 0, -3);
$query .= ")";

echo $query . "<br>";
$stmt=$dbh->prepare($query);
$stmt->execute();
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
echo "<pre>";
print_r ($results );
echo "</pre>";

It's a reference to the current object, it's most commonly used in object oriented code.

• Reference: http://www.php.net/manual/en/language.oop5.basic.php
• Primer: http://www.phpro.org/tutorials/Object-Oriented-Programming-with-PHP.html

Example:

<?php
class Person {
    public $name;

    function __construct( $name ) {
        $this->name = $name;
    }
};

$jack = new Person('Jack');
echo $jack->name;

This stores the 'Jack' string as a property of the object created.

You could use a StringReader and convert the reader to an input stream using the solution in this other stackoverflow post.

It may appear to be overly awkward, but you're probably better off unsetting one element at a time rather than the entire $_POST array. Here's why: If you're using object-oriented programming, you may have one class use $_POST['alpha'] and another class use $_POST['beta'], and if you unset the array after first use, it will void its use in other classes. To be safe and not shoot yourself in the foot, just drop in a little method that will unset the elements that you've just used: For example:

private function doUnset()
{
    unset($_POST['alpha']);
    unset($_POST['gamma']);
    unset($_POST['delta']);
    unset($_GET['eta']);
    unset($_GET['zeta']);
}

Just call the method and unset just those superglobal elements that have been passed to a variable or argument. Then, the other classes that may need a superglobal element can still use them.

However, you are wise to unset the superglobals as soon as they have been passed to an encapsulated object.

    protected String toCamelCase(CaseFormat caseFormat, String... words){
        if (words.length  == 0){
          throw new IllegalArgumentException("Word list is empty!");
        }

        String firstWord = words[0];
        String [] restOfWords = Arrays.copyOfRange(words, 1, words.length);

        StringBuffer buffer = new StringBuffer();
        buffer.append(firstWord);
        Arrays.asList(restOfWords).stream().forEach(w->buffer.append("_"+ w.toUpperCase()));

        return CaseFormat.UPPER_UNDERSCORE.to(caseFormat, buffer.toString());

    }

Try this:

String.prototype.toBinaryString = function(spaces = 0) {
    return this.split("").map(function(character) {
        return character.charCodeAt(0).toString(2);
    }).join(" ".repeat(spaces));
}

And use it like this:

"test string".toBinaryString(1); // with spaces
"test string".toBinaryString(); // without spaces
"test string".toBinaryString(2); // with 2 spaces

It is possible and you don't need to code it on your own.

Just set the ringer volume to zero and vibration to none if incomingNumber equals an empty string. Thats it ...

Its just done for you with the application Nostalk from Android Market. Just give it a try ...

<textarea cols='60' rows='8'>This is my statement one.

This is my statement2</textarea>

Fiddle showing that it works: http://jsfiddle.net/trott/5vu28/.

If you really want this to be on a single line in the source file, you could insert the HTML character references for a line feed and a carriage return as shown in the answer from @Bakudan:

  <textarea cols='60' rows='8'>This is my statement one.&#13;&#10;This is my statement2</textarea>

Try eUML2. its a single click generator no need to drag n drop.

try this

INSERT INTO exampleTbl VALUES('he doesn''t work for me')

It is solved by adding the following code in app.js file

app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
app.set('views', __dirname);

app.get('/', function(req, res){
    res.render("index");
});

You can just use empty() - as seen in the documentation, it will return false if the variable has no value.

An example on that same page:

<?php
$var = 0;

// Evaluates to true because $var is empty
if (empty($var)) {
    echo '$var is either 0, empty, or not set at all';
}

// Evaluates as true because $var is set
if (isset($var)) {
    echo '$var is set even though it is empty';
}
?>

You can use isset if you just want to know if it is not NULL. Otherwise it seems empty() is just fine to use alone.

Try this steps:

1. unplug device
2. adb kill-server
3. adb start-server
4. plug device

You need to allow Allow USB debugging in your device when popup.

And,

Think of the ? as to mean "unknown". Thus, "ArrayList<? extends Object>" is to say "an unknown type that (or as long as it)extends Object". Therefore, needful to say, arrayList.add(3) would be putting something you know, into an unknown. I.e 'Forgetting'.

READ AT LEAST THE FIRST PARA HERE!

I know this is 3 years too late, but Matt's (accepted) answer is incomplete and will eventually get you into trouble. The key here is that, if you choose to use multipart/form-data, the boundary must not appear in the file data that the server eventually receives.

This is not a problem for application/x-www-form-urlencoded, because there is no boundary. x-www-form-urlencoded can also always handle binary data, by the simple expedient of turning one arbitrary byte into three 7BIT bytes. Inefficient, but it works (and note that the comment about not being able to send filenames as well as binary data is incorrect; you just send it as another key/value pair).

The problem with multipart/form-data is that the boundary separator must not be present in the file data (see RFC 2388; section 5.2 also includes a rather lame excuse for not having a proper aggregate MIME type that avoids this problem).

So, at first sight, multipart/form-data is of no value whatsoever in any file upload, binary or otherwise. If you don't choose your boundary correctly, then you will eventually have a problem, whether you're sending plain text or raw binary - the server will find a boundary in the wrong place, and your file will be truncated, or the POST will fail.

The key is to choose an encoding and a boundary such that your selected boundary characters cannot appear in the encoded output. One simple solution is to use base64 (do not use raw binary). In base64 3 arbitrary bytes are encoded into four 7-bit characters, where the output character set is [A-Za-z0-9+/=] (i.e. alphanumerics, '+', '/' or '='). = is a special case, and may only appear at the end of the encoded output, as a single = or a double ==. Now, choose your boundary as a 7-bit ASCII string which cannot appear in base64 output. Many choices you see on the net fail this test - the MDN forms docs, for example, use "blob" as a boundary when sending binary data - not good. However, something like "!blob!" will never appear in base64 output.

function doThen(conditional,then,timer) {
    var timer = timer || 1;
    var interval = setInterval(function(){
        if(conditional()) {
            clearInterval(interval);
            then();
        }
    }, timer);
}

Example usage:

var counter = 1;
doThen(
    function() {
        counter++;
        return counter == 1000;
    },
    function() {
        console.log("Counter hit 1000"); // 1000 repeats later
    }
)

If you use JAVA it's as simple as this:

Polymorphism is using inherited methods but "Overriding" them to do something different (or the same if you call super so wouldn't technically be polymorphic).

Correct me if I'm wrong.

you should change the adb port with this command:

adb reverse tcp:8880 tcp:8880; adb reverse tcp:8081 tcp:8081; adb reverse tcp:8881 tcp:8881

You can use the following:

plt.hold(True)

Create a function to call your API. Within this function we define request callApiRequest = $.get(... - even though this is a definition of a variable, the request is called immediately, but now we have the request defined as a variable. Before the request is called, we check if our variable is defined typeof(callApiRequest) != 'undefined' and also if it is pending suggestCategoryRequest.state() == 'pending' - if both are true, we .abort() the request which will prevent the success callback from running.

// We need to wrap the call in a function
callApi = function () {

    //check if request is defined, and status pending
    if (typeof(callApiRequest) != 'undefined'
        && suggestCategoryRequest.state() == 'pending') {

        //abort request
        callApiRequest.abort()

    }

    //define and make request
    callApiRequest = $.get("https://example.com", function (data) {

        data = JSON.parse(data); //optional (for JSON data format)
        //success callback

    });
}

Your server/API might not support aborting the request (what if API executed some code already?), but the javascript callback will not fire. This is useful, when for example you are providing input suggestions to a user, such as hashtags input.

You can further extend this function by adding definition of error callback - what should happen if request was aborted.

Common use-case for this snippet would be a text input that fires on keypress event. You can use a timeout, to prevent sending (some of) requests that you will have to cancel .abort().

window.history.pushState({urlPath:'/page1'},"",'/page1')

Only works after page is loaded, and when you will click on refresh it doesn't mean that there is any real URL.

What you should do here is knowing to which URL you are getting redirected when you reload this page. And on that page you can get the conditions by getting the current URL and making all of your conditions.

This is an old question and its been answered but I thought I'd put the --binary-files=text option here for anyone who wants to use it. The -I option ignores the binary file but if you want the grep to treat the binary file as a text file use --binary-files=text like so:

bash$ grep -i reset mediaLog*
Binary file mediaLog_dc1.txt matches
bash$ grep --binary-files=text -i reset mediaLog*
mediaLog_dc1.txt:2016-06-29 15:46:02,470 - Media [uploadChunk  ,315] - ERROR - ('Connection aborted.', error(104, 'Connection reset by peer'))
mediaLog_dc1.txt:ConnectionError: ('Connection aborted.', error(104, 'Connection reset by peer'))
bash$

As long as checker is not null, you may use !checker as posted. This is possible since Java 5, because this Boolean variable will be autoboxed to the primivite boolean value.

Here is what you do in Excel 2003:

1. In your sheet of interest, go to Format -> Sheet -> Hide and hide your sheet.
2. Go to Tools -> Protection -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Here is what you do in Excel 2007:

1. In your sheet of interest, go to Home ribbon -> Format -> Hide & Unhide -> Hide Sheet and hide your sheet.
2. Go to Review ribbon -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Once this is done, the sheet is hidden and cannot be unhidden without the password. Make sense?

If you really need to keep some calculations secret, try this: use Access (or another Excel workbook or some other DB of your choice) to calculate what you need calculated, and export only the "unclassified" results to your Excel workbook.

For live video conferencing you can't ignore the need of a streaming server.

Yes, flash will let you display video from a webcam within the local flash control, but that won't let you then send that video over the network - for that you need a streaming server to send it to.

If you're going to build something like this it's prudent to think about how you're going to host the video from a very early stage as it will influence how you build the application. Flash/Flex/Silverlight/Windows Media....etc....

You either need to keep creating new objects, or clone the existing one. See What is the most efficient way to deep clone an object in JavaScript? for how to clone.

npm start will run whatever you have defined for the start command of the scripts object in your package.json file.

So if it looks like this:

"scripts": {
  "start": "ng serve"
}

Then npm start will run ng serve.

I have used this form of switch-case on rare occasion. Even then I have found another way to do what I wanted. If you find that this is the only way to accomplish what you need, I would recommend @Mark H's solution.

If this is intended to be a sort of factory creation decision process, there are better ways to do it. Otherwise, I really can't see why you want to use the switch on a type.

Here is a little example expanding on Mark's solution. I think it is a great way to work with types:

Dictionary<Type, Action> typeTests;

public ClassCtor()
{
    typeTests = new Dictionary<Type, Action> ();

    typeTests[typeof(int)] = () => DoIntegerStuff();
    typeTests[typeof(string)] = () => DoStringStuff();
    typeTests[typeof(bool)] = () => DoBooleanStuff();
}

private void DoBooleanStuff()
{
   //do stuff
}

private void DoStringStuff()
{
    //do stuff
}

private void DoIntegerStuff()
{
    //do stuff
}

public Action CheckTypeAction(Type TypeToTest)
{
    if (typeTests.Keys.Contains(TypeToTest))
        return typeTests[TypeToTest];

    return null; // or some other Action delegate
}

You can also use the special word like:

Public Sub Search()
  If "My Big String with, in the middle" Like "*,*" Then
    Debug.Print ("Found ','")
  End If
End Sub

String name = android.os.Build.USER;

if (!TextUtils.isEmpty(name)) {
    nameEdit.setText(name);
}

I'll add something that helps me out a lot with cygwin. Whenever setting up a new system, I always do this

ln -s /cygdrive/c /c

This creates a symbolic link to /cygdrive/c with a new file called /c (in the home directory)

Then you can do this in your shell

cd /c/Foo
cd /c/

Very handy.

This can also happen if CMAKE_FIND_ROOT_PATH is set as different from BOOST_ROOT. I faced the same issue that in spite of setting BOOST_ROOT, I was getting the error. But for cross compiling for ARM I was using Toolchain-android.cmake in which I had (for some reason):

set(BOOST_ROOT "/home/.../boost")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} --sysroot=${SYSROOT}")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} --sysroot=${SYSROOT} -I${SYSROOT}/include/libcxx")
set(CMAKE_CXX_LINK_FLAGS "${CMAKE_CXX_LINK_FLAGS}")
set(CMAKE_FIND_ROOT_PATH "${SYSROOT}")

CMAKE_FIND_ROOT_PATH seems to be overriding BOOST_ROOT which was causing the issue.

Almost there! The escape sequence for a brace is {{ or }} so for your example you would use:

string t = "1, 2, 3";
string v = String.Format(" foo {{{0}}}", t);

From Python 3.0 changelog;

The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively.

From the Python 3 email documentation it can be seen that io.StringIO should be used instead:

from io import StringIO
from email.generator import Generator
fp = StringIO()
g = Generator(fp, mangle_from_=True, maxheaderlen=60)
g.flatten(msg)
text = fp.getvalue()

Reference: https://docs.python.org/3/library/io.html

Another option is to use a single authorize filter as you posted but remove the inner quotations.

[Authorize(Roles="members,admin")]

You can use .find():

map<string,string>::iterator i = m.find("f");

if (i == m.end()) { /* Not found */ }
else { /* Found, i->first is f, i->second is ++-- */ }

You can also do something like this

 class Hello {_x000D_
     constructor(){_x000D_
     }_x000D_
    }_x000D_
    _x000D_
      function isClass (func) {_x000D_
        return typeof func === 'function' && /^class\s/.test(Function.prototype.toString.call(func))_x000D_
    }_x000D_
    _x000D_
   console.log(isClass(Hello))

This will tell you if the input is class or not

According to my experience, in console apps the easiest way to read the last key pressed is as follows (Example with arrow keys):

ConsoleKey readKey = Console.ReadKey ().Key;
if (readKey == ConsoleKey.LeftArrow) {
    <Method1> ();  //Do something
} else if (readKey == ConsoleKey.RightArrow) {
    <Method2> ();  //Do something
}

I use to avoid loops, instead I write the code above within a method, and I call it at the end of both "Method1" and "Method2", so, after executing "Method1" or "Method2", Console.ReadKey().Key is ready to read the keys again.

Recently I came across an issue in grep. I was trying to match the pattern x.y.z and grep returned x.y-z.Using some regular expression we may can overcome this, but with grep whole word matching did not help. Since the script I was writing is a generic one, I cannot restrict search for a specific way as in like x.y.z or x.y-z ..

Quick way I figured is to run a grep and then a condition check var="x.y.z" var1=grep -o x.y.z file.txt if [ $var1 == $var ] echo "Pattern match exact" else echo "Pattern does not match exact" fi

I think jQuery cannot find the element.

First of all find the element

var rowTemplate= document.getElementsByName("rowTemplate");

or

var rowTemplate = document.getElementById("rowTemplate"); 

or

var rowTemplate = $('#rowTemplate');

Then try your code again

rowTemplate.html().replace(....)

I think this link demonstrates the best way to get application context anywhere, even in the non-bean class. I find it very useful. Hope its the same for you. The below is the abstract code of it

Create a new class ApplicationContextProvider.java

package com.java2novice.spring;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class ApplicationContextProvider implements ApplicationContextAware{

    private static ApplicationContext context;

    public static ApplicationContext getApplicationContext() {
        return context;
    }

    @Override
    public void setApplicationContext(ApplicationContext ac)
            throws BeansException {
        context = ac;
    }
}

Add an entry in application-context.xml

<bean id="applicationContextProvider"
                        class="com.java2novice.spring.ApplicationContextProvider"/>

In annotations case (instead of application-context.xml)

@Component
public class ApplicationContextProvider implements ApplicationContextAware{
...
}

Get the context like this

TestBean tb = ApplicationContextProvider.getApplicationContext().getBean("testBean", TestBean.class);

Cheers!!

Here is a way to calculate memory usage of currently running application:

public static long getUsedMemorySize() {

    long freeSize = 0L;
    long totalSize = 0L;
    long usedSize = -1L;
    try {
        Runtime info = Runtime.getRuntime();
        freeSize = info.freeMemory();
        totalSize = info.totalMemory();
        usedSize = totalSize - freeSize;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return usedSize;

}

Communication between controllers is done though $emit + $on / $broadcast + $on methods.

So in your case you want to call a method of Controller "One" inside Controller "Two", the correct way to do this is:

app.controller('One', ['$scope', '$rootScope'
    function($scope) {
        $rootScope.$on("CallParentMethod", function(){
           $scope.parentmethod();
        });

        $scope.parentmethod = function() {
            // task
        }
    }
]);
app.controller('two', ['$scope', '$rootScope'
    function($scope) {
        $scope.childmethod = function() {
            $rootScope.$emit("CallParentMethod", {});
        }
    }
]);

While $rootScope.$emit is called, you can send any data as second parameter.

So after research the following is discovered:

For a div#bar setting display:block; width: auto; causes the equivalent of outerWidth:100%;

For a table#bar you need to wrap it in a div with the rules stated below. So your structure becomes:

<div id="foo">
 <div id="barWrap" style="border....">
  <table id="bar" style="width: 100%; border: 0; padding: 0; margin: 0;">

This way the table takes up the parent div 100%, and #barWrap is used to add borders/margin/padding to the #bar table. Note that you will need to set the background of the whole thing in #barWrap and have #bar's background be transparent or the same as #barWrap.

For textarea#bar and input#bar you need to do the same thing as table#bar, the down side is that by removing the borders you stop native widget rendering of the input/textarea and the #barWrap's borders will look a bit different than everything else, so you will probably have to style all your inputs this way.

You say in a comment you want to get "15.09.2016".

For this, use Date and DateFormatter:

let date = Date()
let formatter = DateFormatter()

Give the format you want to the formatter:

formatter.dateFormat = "dd.MM.yyyy"

Get the result string:

let result = formatter.string(from: date)

Set your label:

label.text = result

Result:

15.09.2016

You can call CREATE Function near the beginning of your script and DROP Function near the end.

I got the error while trying to develop while disconnected to the Internet. However, the website I was working on needs to be able to talk to some other websites, so it choked when it couldn't do so. Connecting to the internet fixed the error.

    background: #F1F1F2;    
}

Working example

Consider a server which has the information of users, missions and their reward points.

1. Users and Reward Points are the resources
2. An end point can relate to more than one resource
3. Endpoints can be described using either a description or a full or partial URL

• Improving Entity Framework Query Performance Using Graph-Based Querying.

The article presents a new way of expressing queries that span multiple tables in the form of declarative graph shapes.

Moreover, the article contains a thorough performance comparison of this new approach with EF queries. This analysis shows that GBQ quickly outperforms EF queries.

There are jQuery-plugins that help you achieve this like: http://ricostacruz.com/jquery.transit/

You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree option for single commands, or the GIT_WORK_TREE environment variable. There is also the core.worktree configuration option but it will not work in a bare repository (check the man page for what it does).

# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status

(ps: the answer given by Nick Craver is incorrect)

contentType specifies the format of data being sent to the server as part of request(it can be sent as part of response too, more on that later).

dataType specifies the expected format of data to be received by the client(browser).

Both are not interchangable.

• contentType is the header sent to the server, specifying the format of data(i.e the content of message body) being being to the server. This is used with POST and PUT requests. Usually when u send POST request, the message body comprises of passed in parameters like:

==============================

Sample request:

POST /search HTTP/1.1 
Content-Type: application/x-www-form-urlencoded 
<<other header>>

name=sam&age=35

==============================

The last line above "name=sam&age=35" is the message body and contentType specifies it as application/x-www-form-urlencoded since we are passing the form parameters in the message body. However we aren't limited to just sending the parameters, we can send json, xml,... like this(sending different types of data is especially useful with RESTful web services):

==============================

Sample request:

POST /orders HTTP/1.1
Content-Type: application/xml
<<other header>>

<order>
   <total>$199.02</total>
   <date>December 22, 2008 06:56</date>
...
</order>

==============================

So the ContentType this time is: application/xml, cause that's what we are sending. The above examples showed sample request, similarly the response send from the server can also have the Content-Type header specifying what the server is sending like this:

==============================

sample response:

HTTP/1.1 201 Created
Content-Type: application/xml
<<other headers>>

<order id="233">
   <link rel="self" href="http://example.com/orders/133"/>
   <total>$199.02</total>
   <date>December 22, 2008 06:56</date>
...
</order>

==============================

• dataType specifies the format of response to expect. Its related to Accept header. JQuery will try to infer it based on the Content-Type of the response.

==============================

Sample request:

GET /someFolder/index.html HTTP/1.1
Host: mysite.org
Accept: application/xml
<<other headers>>

==============================

Above request is expecting XML from the server.

Regarding your question,

contentType: "application/json; charset=utf-8",
dataType: "json",

Here you are sending json data using UTF8 character set, and you expect back json data from the server. As per the JQuery docs for dataType,

The json type parses the fetched data file as a JavaScript object and returns the constructed object as the result data.

So what you get in success handler is proper javascript object(JQuery converts the json object for you)

whereas

contentType: "application/json",
dataType: "text",

Here you are sending json data, since you haven't mentioned the encoding, as per the JQuery docs,

If no charset is specified, data will be transmitted to the server using the server's default charset; you must decode this appropriately on the server side.

and since dataType is specified as text, what you get in success handler is plain text, as per the docs for dataType,

The text and xml types return the data with no processing. The data is simply passed on to the success handler

If you don't need to sum a column, then use @tvashtar's answer. If you do need to sum, then you can use @joris' answer or this one which is very similar to it.

df.groupby(['job']).apply(lambda x: (x.groupby('source')
                                      .sum()
                                      .sort_values('count', ascending=False))
                                     .head(3))

maybe you need to set your window-size dimension. just like:

options = webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
options.add_argument('--window-size=1920x1080');

browser = webdriver.Chrome(options=options,executable_path = './chromedriver')

if also not working, try increase window-size dimension.

I know I'm really late to this party, but here's my one liner to determine admin-hood.

It doesn't rely on error level, just on systeminfo:

for /f "tokens=1-6" %%a in ('"net user "%username%" | find /i "Local Group Memberships""') do (set admin=yes & if not "%%d" == "*Administrators" (set admin=no) & echo %admin%)

It returns either yes or no, depending on the user's admin status...

It also sets the value of the variable "admin" to equal yes or no accordingly.

easiest way to append class name using javascript. It can be useful when .siblings() are misbehaving.

document.getElementById('myId').className += ' active';

With small custom synchronization context, sync function can wait for completion of async function, without creating deadlock. Here is small example for WinForms app.

Imports System.Threading
Imports System.Runtime.CompilerServices

Public Class Form1

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        SyncMethod()
    End Sub

    ' waiting inside Sync method for finishing async method
    Public Sub SyncMethod()
        Dim sc As New SC
        sc.WaitForTask(AsyncMethod())
        sc.Release()
    End Sub

    Public Async Function AsyncMethod() As Task(Of Boolean)
        Await Task.Delay(1000)
        Return True
    End Function

End Class

Public Class SC
    Inherits SynchronizationContext

    Dim OldContext As SynchronizationContext
    Dim ContextThread As Thread

    Sub New()
        OldContext = SynchronizationContext.Current
        ContextThread = Thread.CurrentThread
        SynchronizationContext.SetSynchronizationContext(Me)
    End Sub

    Dim DataAcquired As New Object
    Dim WorkWaitingCount As Long = 0
    Dim ExtProc As SendOrPostCallback
    Dim ExtProcArg As Object

    <MethodImpl(MethodImplOptions.Synchronized)>
    Public Overrides Sub Post(d As SendOrPostCallback, state As Object)
        Interlocked.Increment(WorkWaitingCount)
        Monitor.Enter(DataAcquired)
        ExtProc = d
        ExtProcArg = state
        AwakeThread()
        Monitor.Wait(DataAcquired)
        Monitor.Exit(DataAcquired)
    End Sub

    Dim ThreadSleep As Long = 0

    Private Sub AwakeThread()
        If Interlocked.Read(ThreadSleep) > 0 Then ContextThread.Resume()
    End Sub

    Public Sub WaitForTask(Tsk As Task)
        Dim aw = Tsk.GetAwaiter

        If aw.IsCompleted Then Exit Sub

        While Interlocked.Read(WorkWaitingCount) > 0 Or aw.IsCompleted = False
            If Interlocked.Read(WorkWaitingCount) = 0 Then
                Interlocked.Increment(ThreadSleep)
                ContextThread.Suspend()
                Interlocked.Decrement(ThreadSleep)
            Else
                Interlocked.Decrement(WorkWaitingCount)
                Monitor.Enter(DataAcquired)
                Dim Proc = ExtProc
                Dim ProcArg = ExtProcArg
                Monitor.Pulse(DataAcquired)
                Monitor.Exit(DataAcquired)
                Proc(ProcArg)
            End If
        End While

    End Sub

     Public Sub Release()
         SynchronizationContext.SetSynchronizationContext(OldContext)
     End Sub

Using Concat on the group by will work

SELECT clients.id, clients.name, portfolios.id, SUM ( portfolios.portfolio + portfolios.cash ) AS total
FROM clients, portfolios
WHERE clients.id = portfolios.client_id
GROUP BY CONCAT(portfolios.id, "-", clients.id)
ORDER BY total DESC
LIMIT 30

jQuery recently started using source maps.

For example, let's look at the minified jQuery 2.0.3 file's first few lines.

/*! jQuery v2.0.3 | (c) 2005, 2013 jQuery Foundation, Inc. | jquery.org/license
//@ sourceMappingURL=jquery.min.map
*/

Excerpt from Introduction to JavaScript Source Maps:

Have you ever found yourself wishing you could keep your client-side code readable and more importantly debuggable even after you've combined and minified it, without impacting performance? Well now you can through the magic of source maps.

Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location. Developer tools (currently WebKit nightly builds, Google Chrome, or Firefox 23+) can parse the source map automatically and make it appear as though you're running unminified and uncombined files.

^{emphasis mine}

It's incredibly useful, and will only download if the user opens dev tools.

Solution

Remove the source mapping line, or do nothing. It isn't really a problem.

Side note: your server should return 404, not 500. It could point to a security problem if this happens in production.

You can also open a required file through a prompt, This helps when you want to select file from different path and different file.

Sub openwb()
Dim wkbk As Workbook
Dim NewFile As Variant

NewFile = Application.GetOpenFilename("microsoft excel files (*.xlsm*), *.xlsm*")

If NewFile <> False Then
Set wkbk = Workbooks.Open(NewFile)
End If
End Sub

Bootstrap 4:

<div class="w-100"></div>

A riot.js solution:

My riot.js Example nests the animated-modal tag inside an order profile tag.

Note, this assumes jquery and riot.js is loaded before.

animated-modal tag contents:

<a id='{ opts.el }' href="" class='pull-right'>edit</a>

    <div class="modal animated" id="{ opts.el }-modal" tabindex="-1" role="dialog" aria-labelledby="animatedModal">
      <div class="modal-dialog modal-lg">
        <div class="modal-content">
          <div class="modal-header">
            <button onclick={ cancelForm } id='{ opts.el }-cancel-1' type="button" class="close" ><span>&times;</span></button>
            <h4 class="modal-title" id="animatedModal">{ opts.title }</h4>
          </div>
          <div class="modal-body">
              <yield/>
          </div>
          <div class="modal-footer">
            <button onclick={ cancelForm } id='{ opts.el }-cancel-2' onclick={ cancelForm } type="button" class="btn btn-default">Close</button>
            <button onclick={ saveForm } type="button" class="btn btn-primary">Save changes</button>
          </div>

        </div>
      </div>
    </div>

    <script>
    var self = this
    self.modalBtn = `#${opts.el}`
    self.modal = `#${opts.el}-modal`
    self.animateInClass = opts.animatein || 'fadeIn'
    self.animateOutClass = opts.animateout || 'fadeOut'
    self.closeModalBtn = `#${ opts.el }-cancel-1, #${ opts.el }-cancel-2`
    self.animationsStr = 'webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend'

    this.on('mount',function(){
        self.initModal()
        self.update()
    })

    this.initModal = function(){
        modal = $(self.modal)
        modalBtn = $(self.modalBtn)
        closeModalBtn = `#${ opts.el }-cancel-1`

        modalBtn.click(function(){
            $(self.modal).addClass(self.animateInClass)
            $(self.modal).modal('show') 
        })

        $(self.modal).on('show.bs.modal',function(){
            $(self.closeModalBtn).one('click',function(){
                $(self.modal).removeClass(self.animateInClass).addClass(self.animateOutClass)

                $(self.modal).on(self.animationsStr,function(){
                    $(self.modal).modal('hide') 
                })
            })
        })

        $(self.modal).on('hidden.bs.modal',function(evt){
            $(self.modal).removeClass(self.animateOutClass)
            $(self.modal).off(self.animationsStr)
            $(self.closeModalBtn).off('click')
        })
    }

    this.cancelForm = function(e){
        this.parent.cancelForm()
    }

    this.showEdit = function(e){
        this.parent.showEdit()
    }

    this.saveForm = function(e){
        this.parent.saveForm()
    }

    dashboard_v2.bus.on('closeModal',function(){
        try{
            $(`#${ opts.el }-cancel-1`).trigger('click')
        }catch(e){}

    })
</script>

And the Profile Tag to nest in:

profile tag contents:

<div class="row">
        <div class="col-md-12">
            <div class="eshop-product-body">

                <animated-modal>
                    title='Order Edit'
                    el='order-modal-1'>

                    <div class="row">
                        <div class="col-md-6 col-md-offset-3">
                            <form id='profile-form'>
                                <div class="form-group">
                                    <label>Organization</label>
                                    <input id='organization' type="text" class="form-control" id="exampleInputEmail1" placeholder="Email">
                                </div>

                                <div class="form-group">
                                    <label>Contact</label>
                                    <input id='contact' type="text" class="form-control" id="exampleInputEmail1" placeholder="Email">
                                </div>

                                <div class="form-group">

                                </div>

                                <div class="form-group">
                                    <label>Email</label>

                        </div>
                    </div>

                </animated-modal>

                <h3>Profile</h3>

                <ul class='profile-list'>
                    <li>Organization: { opts.data.profile.organization }</li>
                    <li>Contact: { opts.data.profile.contact_full_name }</li>

    <script>
        var self = this     

        this.on('mount',function(){

        })

        this.cancelForm = function(e){

        }

        this.showEdit = function(e){

        }

        this.saveForm = function(e){

You can refresh the events after adding new ones by applying the following code: -Release the Events -set Event Source -Re-render Events

  $('#calendar').fullCalendar('removeEvents');
                  $('#calendar').fullCalendar('addEventSource', YoureventSource);         
                  $('#calendar').fullCalendar('rerenderEvents' );

That will solve the problem

I was able to solve this problem by replacing the following:

In the Toolbar layout, replace everything which is like this:

android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"

with

android:minHeight="@dimen/abc_action_bar_default_height_material"
android:background="@color/myColor"
