I needed to do a count of a very complex query with many joins. I was using the joins as filters, so I only wanted to know the count of the actual objects. count() was insufficient, but I found the answer in the docs here:

http://docs.sqlalchemy.org/en/latest/orm/tutorial.html

The code would look something like this (to count user objects):

from sqlalchemy import func

session.query(func.count(User.id)).scalar() 

There is another scenario where this issue reproduces (as in my case). When THE CLIENT REQUEST doesn't contain the right extension on the url, the controller can't identify the desired result format.

For example: the controller is set to respond_to :json (as a single option, without a HTML response)- while the client call is set to /reservations instead of /reservations.json.

Bottom line, change the client call to /reservations.json.

Try this:

Display display   = getWindowManager().getDefaultDisplay();
Point displaySize = new Point();
display.getSize(displaySize);
int width  = displaySize.x;
int height = displaySize.y;

IMO, you need to work with such directories as usual, but instead of checking permissions before use, provide the correct way to handle UnauthorizedAccessException and react accordingly. This method is easier and much less error prone.

It's a while since I've seen that message, but it used to be prevalent in System V R3 or thereabouts a good couple of decades ago. Back then, it meant that you could not change a program executable while it was running.

For example, I was building a make workalike called rmk, and after a while it was self-maintaining. I would run the development version and have it build a new version. To get it to work, it was necessary to use the workaround:

gcc -g -Wall -o rmk1 main.o -L. -lrmk -L/Users/jleffler/lib/64 -ljl
if [ -f rmk ] ; then mv rmk rmk2 ; else true; fi ; mv rmk1 rmk

So, to avoid problems with the 'text file busy', the build created a new file rmk1, then moved the old rmk to rmk2 (rename wasn't a problem; unlink was), and then moved the newly built rmk1 to rmk.

I haven't seen the error on a modern system in quite a while...but I don't all that often have programs rebuilding themselves.

<table>
     <ng-container *ngFor="let group of groups">
         <tr><td><h2>{{group.name}}</h2></td></tr>
         <tr *ngFor="let item of group.items"><td>{{item}}</td></tr>
     </ng-container>
</table>

Use :

FileInfo fInfo = new FileInfo('FilePath');
var fFirstTime = fInfo.CreationTime;
var fLastTime = fInfo.LastWriteTime;

SELECT COUNT(*) FROM information_schema.tables WHERE table_schema = 'database_name';

Wouldn't that just be something like this:

Textbox myTxtbx = new Textbox();
myTxtbx.Text = "Enter text here...";

myTxtbx.GotFocus += GotFocus.EventHandle(RemoveText);
myTxtbx.LostFocus += LostFocus.EventHandle(AddText);

public void RemoveText(object sender, EventArgs e)
{
    if (myTxtbx.Text == "Enter text here...") 
    {
     myTxtbx.Text = "";
    }
}

public void AddText(object sender, EventArgs e)
{
    if (string.IsNullOrWhiteSpace(myTxtbx.Text))
        myTxtbx.Text = "Enter text here...";
}

Thats just pseudocode but the concept is there.

First of all it's a little bit harder using just counting analysis to tell if your data is unbalanced or not. For example: 1 in 1000 positive observation is just a noise, error or a breakthrough in science? You never know.
So it's always better to use all your available knowledge and choice its status with all wise.

Okay, what if it's really unbalanced?
Once again — look to your data. Sometimes you can find one or two observation multiplied by hundred times. Sometimes it's useful to create this fake one-class-observations.
If all the data is clean next step is to use class weights in prediction model.

So what about multiclass metrics?
In my experience none of your metrics is usually used. There are two main reasons.
First: it's always better to work with probabilities than with solid prediction (because how else could you separate models with 0.9 and 0.6 prediction if they both give you the same class?)
And second: it's much easier to compare your prediction models and build new ones depending on only one good metric.
From my experience I could recommend logloss or MSE (or just mean squared error).

How to fix sklearn warnings?
Just simply (as yangjie noticed) overwrite average parameter with one of these values: 'micro' (calculate metrics globally), 'macro' (calculate metrics for each label) or 'weighted' (same as macro but with auto weights).

f1_score(y_test, prediction, average='weighted')

All your Warnings came after calling metrics functions with default average value 'binary' which is inappropriate for multiclass prediction.
Good luck and have fun with machine learning!

Edit:
I found another answerer recommendation to switch to regression approaches (e.g. SVR) with which I cannot agree. As far as I remember there is no even such a thing as multiclass regression. Yes there is multilabel regression which is far different and yes it's possible in some cases switch between regression and classification (if classes somehow sorted) but it pretty rare.

What I would recommend (in scope of scikit-learn) is to try another very powerful classification tools: gradient boosting, random forest (my favorite), KNeighbors and many more.

After that you can calculate arithmetic or geometric mean between predictions and most of the time you'll get even better result.

final_prediction = (KNNprediction * RFprediction) ** 0.5

@RequestMapping("/api/status")
public Map doSomething()
{
    return Collections.singletonMap("status", myService.doSomething());
}

PS. Works only for 1 value

In addition to move_to_element() and scrollIntoView() I wanted to pose the following code which attempts to center the element in the view:

desired_y = (element.size['height'] / 2) + element.location['y']
window_h = driver.execute_script('return window.innerHeight')
window_y = driver.execute_script('return window.pageYOffset')
current_y = (window_h / 2) + window_y
scroll_y_by = desired_y - current_y

driver.execute_script("window.scrollBy(0, arguments[0]);", scroll_y_by)

Use the range type. If the user enter a date:

select *
from table
where
    update_date
    <@
    tsrange('2013-05-03', '2013-05-03'::date + 1, '[)');

If the user enters timestamps then you don't need the ::date + 1 part

http://www.postgresql.org/docs/9.2/static/rangetypes.html

http://www.postgresql.org/docs/9.2/static/functions-range.html

Any API should check the validity of the every parameter of any public method before executing it:

void setPercentage(int pct, AnObject object) {
    if( pct < 0 || pct > 100) {
        throw new IllegalArgumentException("pct has an invalid value");
    }
    if (object == null) {
        throw new IllegalArgumentException("object is null");
    }
}

They represent 99.9% of the times errors in the application because it is asking for impossible operations so in the end they are bugs that should crash the application (so it is a non recoverable error).

In this case and following the approach of fail fast you should let the application finish to avoid corrupting the application state.

After searching a solution that supports Safari and other browsers (Internet Explorer 9 and later),

I use the same as GitHub: ZeroClipboard

Example:

http://zeroclipboard.org/index-v1.x.html

HTML

<html>
  <body>
    <button id="copy-button" data-clipboard-text="Copy Me!" title="Click to copy me.">Copy to Clipboard</button>
    <script src="ZeroClipboard.js"></script>
    <script src="main.js"></script>
  </body>
</html>

JavaScript

var client = new ZeroClipboard(document.getElementById("copy-button"));

client.on("ready", function (readyEvent) {
    // alert( "ZeroClipboard SWF is ready!" );

    client.on("aftercopy", function (event) {
        // `this` === `client`
        // `event.target` === the element that was clicked
        event.target.style.display = "none";
        alert("Copied text to clipboard: " + event.data["text/plain"]);
    });
});

If you want to set the form's back color to some arbitrary RGB value, you can do this:

this.BackColor = Color.FromArgb(255, 232, 232); // this should be pink-ish

It should be noted that the documentation recommends using a Layout rather than Canvas.drawText directly. My full answer about using a StaticLayout is here, but I will provide a summary below.

String text = "This is some text.";

TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);

int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);

Here is a fuller example in the context of a custom view:

public class MyView extends View {

    String mText = "This is some text.";
    TextPaint mTextPaint;
    StaticLayout mStaticLayout;

    // use this constructor if creating MyView programmatically
    public MyView(Context context) {
        super(context);
        initLabelView();
    }

    // this constructor is used when created from xml
    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initLabelView();
    }

    private void initLabelView() {
        mTextPaint = new TextPaint();
        mTextPaint.setAntiAlias(true);
        mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
        mTextPaint.setColor(0xFF000000);

        // default to a single line of text
        int width = (int) mTextPaint.measureText(mText);
        mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);

        // New API alternate
        //
        // StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
        //        .setAlignment(Layout.Alignment.ALIGN_NORMAL)
        //        .setLineSpacing(1, 0) // multiplier, add
        //        .setIncludePad(false);
        // mStaticLayout = builder.build();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // Tell the parent layout how big this view would like to be
        // but still respect any requirements (measure specs) that are passed down.

        // determine the width
        int width;
        int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
        if (widthMode == MeasureSpec.EXACTLY) {
            width = widthRequirement;
        } else {
            width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
            if (widthMode == MeasureSpec.AT_MOST) {
                if (width > widthRequirement) {
                    width = widthRequirement;
                    // too long for a single line so relayout as multiline
                    mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
                }
            }
        }

        // determine the height
        int height;
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
        if (heightMode == MeasureSpec.EXACTLY) {
            height = heightRequirement;
        } else {
            height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
            if (heightMode == MeasureSpec.AT_MOST) {
                height = Math.min(height, heightRequirement);
            }
        }

        // Required call: set width and height
        setMeasuredDimension(width, height);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        // do as little as possible inside onDraw to improve performance

        // draw the text on the canvas after adjusting for padding
        canvas.save();
        canvas.translate(getPaddingLeft(), getPaddingTop());
        mStaticLayout.draw(canvas);
        canvas.restore();
    }
}

If you want to show just numbers without characters, put this line of code inside your XML file android:inputType="number". The output:

If you want to show a number keyboard that also shows characters, put android:inputType="phone" on your XML. The output (with characters):

And if you want to show a number keyboard that masks your input just like a password, put android:inputType="numberpassword". The output:

I'm really sorry if I only post the links of the screenshot, I want to do research on how to do really post images here but it might consume my time so here it is. I hope my post can help other people. Yes, my answer is duplicate with other answers posted here but to save other people's time that they might need to run their code before seeing the output, my post might save you some time.

I don't think desc takes an na.rm argument... I'm actually surprised it doesn't throw an error when you give it one. If you just want to remove NAs, use na.omit (base) or tidyr::drop_na:

outcome.df %>%
  na.omit() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

library(tidyr)
outcome.df %>%
  drop_na() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

If you only want to remove NAs from the HeartAttackDeath column, filter with is.na, or use tidyr::drop_na:

outcome.df %>%
  filter(!is.na(HeartAttackDeath)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

outcome.df %>%
  drop_na(HeartAttackDeath) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

As pointed out at the dupe, complete.cases can also be used, but it's a bit trickier to put in a chain because it takes a data frame as an argument but returns an index vector. So you could use it like this:

outcome.df %>%
  filter(complete.cases(.)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

I can't comment due to the lack of reputation, but if you are on arch linux, you should be able to find the corresponding libraries on the arch repositories directly. For example for mpl_toolkits.basemap:

pacman -S python-basemap

According to the site I'll post below, it's all how you set up your server. One example they show is this:

var http = require("http");
var url = require("url");

function start(route, handle) {
  function onRequest(request, response) {
    var pathname = url.parse(request.url).pathname;
    console.log("Request for " + pathname + " received.");

    route(handle, pathname, response);
  }

  http.createServer(onRequest).listen(8888);
  console.log("Server has started.");
}

exports.start = start;

and their route function:

function route(handle, pathname, response) {
  console.log("About to route a request for " + pathname);
  if (typeof handle[pathname] === 'function') {
    handle[pathname](response);
  } else {
    console.log("No request handler found for " + pathname);
    response.writeHead(404, {"Content-Type": "text/plain"});
    response.write("404 Not found");
    response.end();
  }
}

exports.route = route;

This is one way. http://www.nodebeginner.org/

From another site, they create a page and then load it. This might be more of what you're looking for.

fs.readFile('www/404.html', function(error2, data) {
            response.writeHead(404, {'content-type': 'text/html'});
            response.end(data);
        });

The best way for me was using vector with categories in order I need as limits parameter to scale_x_discrete. I think it is pretty simple and straightforward solution.

ggplot(mtcars, aes(factor(cyl))) + 
  geom_bar() + 
  scale_x_discrete(limits=c(8,4,6))

This worked well for me. I hope it will fix your issues too.

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

You can find it here.

Seems like there's a bug with applyFromArray right now that won't accept color, but this worked for me:

$objPHPExcel
    ->getActiveSheet()
    ->getStyle('A1')
    ->getFill()
    ->getStartColor()
    ->setRGB('FF0000');

jQuery provides a method which store data for you, no need to use a dummy attribute or to find workaround to your problem.

Bind the click event:

$('a[href*=/Booking.aspx/Change]').bind('click', function(e) {
    e.preventDefault();
    $("#dialog-confirm")
        .data('link', this)  // The important part .data() method
        .dialog('open');
});

And your dialog:

$("#dialog-confirm").dialog({
    autoOpen: false,
    resizable: false,
    height:200,
    modal: true,
    buttons: {
        Cancel: function() {
            $(this).dialog('close');
        },
        'Delete': function() {
            $(this).dialog('close');
            var path = $(this).data('link').href; // Get the stored result
            $(location).attr('href', path);
        }
    }
});

The following is function would work for async wrap or promise then chains

const readFileAsync =  async (path) => fs.readFileSync(path, 'utf8');

I think clang could be an alternative.

GCC and clang have some differences on expressions like a+++++a, and I've got many different answers with my peer who use clang on Mac while I use gcc.

GCC has become the standard, and clang could be an alternative. Because GCC is very stable and clang is still under developing.

Try this:

void drawInitialNim(int num1, int num2, int num3){
    int board[3][50] = {0}; // This is a local variable. It is not possible to use it after returning from this function. 

    int i, j, k;

    for(i=0; i<num1; i++)
        board[0][i] = 'O';
    for(i=0; i<num2; i++)
        board[1][i] = 'O';
    for(i=0; i<num3; i++)
        board[2][i] = 'O';

    for (j=0; j<3;j++) {
        for (k=0; k<50; k++) {
            if(board[j][k] != 0)
                printf("%c", board[j][k]);
        }
        printf("\n");
    }
}

It seems to be a nasty problem of Gradle. We just upgraded from 2.14 to 3.3 and our build server couldn't build any more (a local build in Android Studio worked).

Error with too long path shows for example:

C:\Windows\System32\config\systemprofile.gradle\caches\3.3\scripts-remapped\build_bonsjy48fqq8sotonpgrvhswt\36ejadunoxgw3iugkh95lqw\projedd7e29570ae79482d0308d82f4e346b\classes\build_bonsjy48fqq8sotonpgrvhswt$_run_closure1$_closure8$_closure13$_closure14$_closure15.class

We had to create a local user account for the service that ran as system service for years... Now it saves under C:\Users... which is much shorter as the system profile path.

My Net 5 solution that also handles null characters at the end:

hex = ConvertFromHex( hex.AsSpan(), Encoding.Default );

static string ConvertFromHex( ReadOnlySpan<char> hexString, Encoding encoding )
{
    int realLength = 0;
    for ( int i = hexString.Length - 2; i >= 0; i -= 2 )
    {
        byte b = byte.Parse( hexString.Slice( i, 2 ), NumberStyles.HexNumber, CultureInfo.InvariantCulture );
        if ( b != 0 ) //not NULL character
        {
            realLength = i + 2;
            break;
        }
    }
    
    var bytes = new byte[realLength / 2];
    for ( var i = 0; i < bytes.Length; i++ )
    {
        bytes[i] = byte.Parse( hexString.Slice( i * 2, 2 ), NumberStyles.HexNumber, CultureInfo.InvariantCulture );
    }

    return encoding.GetString( bytes );
}

With PostgreSQL 9.1 this can be achieved using a writeable CTE (common table expression):

WITH new_values (id, field1, field2) as (
  values 
     (1, 'A', 'X'),
     (2, 'B', 'Y'),
     (3, 'C', 'Z')

),
upsert as

Hashtags at the end of the URL bring a visitor to the element with the ID: e.g.

http://stackoverflow.com/questions/8424785/link-to-a-section-of-a-webpage#answers 

Would bring you to where the DIV with the ID 'answers' begins. Also, you can use the name attribute in anchor tags, to create the same effect.

Resource

Given a data URL, you can create an image (either on the page or purely in JS) by setting the src of the image to your data URL. For example:

var img = new Image;
img.src = strDataURI;

The drawImage() method of HTML5 Canvas Context lets you copy all or a portion of an image (or canvas, or video) onto a canvas.

You might use it like so:

var myCanvas = document.getElementById('my_canvas_id');
var ctx = myCanvas.getContext('2d');
var img = new Image;
img.onload = function(){
  ctx.drawImage(img,0,0); // Or at whatever offset you like
};
img.src = strDataURI;

Edit: I previously suggested in this space that it might not be necessary to use the onload handler when a data URI is involved. Based on experimental tests from this question, it is not safe to do so. The above sequence—create the image, set the onload to use the new image, and then set the src—is necessary for some browsers to surely use the results.

An alternative strict solution using the standard library is to perform the following:

1) Create a strict SimpleDateFormat using your pattern

2) Attempt to parse the user entered value using the format object

3) If successful, reformat the Date resulting from (2) using the same date format (from (1))

4) Compare the reformatted date against the original, user-entered value. If they're equal then the value entered strictly matches your pattern.

This way, you don't need to create complex regular expressions - in my case I needed to support all of SimpleDateFormat's pattern syntax, rather than be limited to certain types like just days, months and years.

FWIW,

Poor mans security folder (to protect a public shared folder from little prying eyes ;) )

mkdir -p {0..9}/{0..9}/{0..9}/{0..9}

Now you can put your files in a pin numbered folder. Not exactly waterproof, but it's a barrier for the youngest.

As far as I can see in the manual, it is not possible to call functions inside HEREDOC strings. A cumbersome way would be to prepare the words beforehand:

<?php

    $world = _("World");

    $str = <<<EOF
    <p>Hello</p>
    <p>$world</p>
EOF;
    echo $str;
?>

a workaround idea that comes to mind is building a class with a magic getter method.

You would declare a class like this:

class Translator
{
 public function __get($name) {
  return _($name); // Does the gettext lookup
  }
 }

Initialize an object of the class at some point:

  $translate = new Translator();

You can then use the following syntax to do a gettext lookup inside a HEREDOC block:

    $str = <<<EOF
    <p>Hello</p>
    <p>{$translate->World}</p>
EOF;
    echo $str;
?>

$translate->World will automatically be translated to the gettext lookup thanks to the magic getter method.

To use this method for words with spaces or special characters (e.g. a gettext entry named Hello World!!!!!!, you will have to use the following notation:

 $translate->{"Hello World!!!!!!"}

This is all untested but should work.

Update: As @mario found out, it is possible to call functions from HEREDOC strings after all. I think using getters like this is a sleek solution, but using a direct function call may be easier. See the comments on how to do this.

Thread interruption is based on flag interrupt status. For every thread default value of interrupt status is set to false. Whenever interrupt() method is called on thread, interrupt status is set to true.

1. If interrupt status = true (interrupt() already called on thread), that particular thread cannot go to sleep. If sleep is called on that thread interrupted exception is thrown. After throwing exception again flag is set to false.
2. If thread is already sleeping and interrupt() is called, thread will come out of sleeping state and throw interrupted Exception.

Using & is fine for short commands, but that single line can get very long very quick. When that happens, switch to multi-line syntax.

FOR /r %%X IN (*.txt) DO (
    ECHO %%X
    DEL %%X
)

Placement of ( and ) matters. The round brackets after DO must be placed on the same line, otherwise the batch file will be incorrect.

See if /?|find /V "" for details.

There are too many points in the process you describe where errors can occur, so I won't try to guess what you're doing wrong, but I think I know what's happening under the hood.

EF BF BD is the UTF-8 encoded form of U+FFFD, the standard replacement character that's inserted by decoders when they encounter malformed input. It sounds like your text is being saved as ISO-8859-1, then read as if it were UTF-8, then saved as UTF-8, then converted to the Properties format using native2ascii using the platform default encoding (e.g., windows-1252).

ü              => 0xFC                // save as ISO-8859-1
0xFC           => U+FFFD              // read as UTF-8
U+FFFD         => 0xEF 0xBF 0xBD      // save as UTF-8
0xEF 0xBF 0xBD => \u00EF\u00BF\u00BD  // native2ascii

I suggest you leave the "file.encoding" property alone. Like "file.separator" and "line.separator", it's not nearly as useful as you would expect it to be. Instead, get into the habit of always specifying an encoding when reading and writing text files.

1. Allocates some dynamic memory from the free store, and creates an object in that memory using its default constructor. You never delete it, so the memory is leaked.
2. Does exactly the same as 1; in the case of user-defined types, the parentheses are optional.
3. Allocates some automatic memory, and creates an object in that memory using its default constructor. The memory is released automatically when the object goes out of scope.
4. Similar to 3. Notionally, the named object foo4 is initialised by default-constructing, copying and destroying a temporary object; usually, this is elided giving the same result as 3.
5. Allocates a dynamic object, then initialises a second by copying the first. Both objects are leaked; and there's no way to delete the first since you don't keep a pointer to it.
6. Does exactly the same as 5.
7. Does not compile. Foo foo5 is a declaration, not an expression; function (and constructor) arguments must be expressions.
8. Creates a temporary object, and initialises a dynamic object by copying it. Only the dynamic object is leaked; the temporary is destroyed automatically at the end of the full expression. Note that you can create the temporary with just Foo() rather than the equivalent Foo::Foo() (or indeed Foo::Foo::Foo::Foo::Foo())

When do I use each?

1. Don't, unless you like unnecessary decorations on your code.
2. When you want to create an object that outlives the current scope. Remember to delete it when you've finished with it, and learn how to use smart pointers to control the lifetime more conveniently.
3. When you want an object that only exists in the current scope.
4. Don't, unless you think 3 looks boring and what to add some unnecessary decoration.
5. Don't, because it leaks memory with no chance of recovery.
6. Don't, because it leaks memory with no chance of recovery.
7. Don't, because it won't compile
8. When you want to create a dynamic Bar from a temporary Foo.

To solve Google security, do this:

Lines to the top:

import android.webkit.SslErrorHandler;
import android.net.http.SslError;

Code:

class SSLTolerentWebViewClient extends WebViewClient {
    @Override
    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
        if (error.toString() == "piglet")
            handler.cancel();
        else
            handler.proceed(); // Ignore SSL certificate errors
    }
}

This worked for me

$("div").css({"left":"2000px"}).animate({"left":"0px"}, "slow");

You only return a value if the current element is a string. Perhaps assigning an empty string otherwise will suffice:

var arr = ['a','b',1];
var results = arr.map(function(item){
    return (typeof item ==='string') ? item : '';  
});

Of course, if you want to filter any non-string elements, you shouldn't use map(). Rather, you should look into using the filter() function.

The steps are as follows:

1. Close WAMP (if running)
2. Navigate to WAMP\bin\php\<your version of PHP>
3. Edit file php.ini
4. Search for curl, uncomment extension=php_curl.dll
5. Navigate to WAMP\bin\Apache\<your version of Apache>\bin\
6. Edit file php.ini
7. Search for curl, uncomment extension=php_curl.dll
8. Save both
9. Restart WAMP

parseFloat(number.toFixed(2))

Example

let number = 2.55435930

let roundedString = number.toFixed(2)    // "2.55"

let twoDecimalsNumber = parseFloat(roundedString)    // 2.55

let directly = parseFloat(number.toFixed(2))    // 2.55

You can use fork() and system() so that your program doesn't have to wait until system() returns.

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

int main(int argc,char* argv[]){

    int status;

    // By calling fork(), a child process will be created as a exact duplicate of the calling process.
    // Search for fork() (maybe "man fork" on Linux) for more information.
    if(fork() == 0){ 
        // Child process will return 0 from fork()
        printf("I'm the child process.\n");
        status = system("my_app");
        exit(0);
    }else{
        // Parent process will return a non-zero value from fork()
        printf("I'm the parent.\n");
    }

    printf("This is my main program and it will continue running and doing anything i want to...\n");

    return 0;
}

Try this

    DataSet ds = new DataSet("TimeRanges");
    using(SqlConnection conn = new SqlConnection("ConnectionString"))
    {               
            SqlCommand sqlComm = new SqlCommand("Procedure1", conn);               
            sqlComm.Parameters.AddWithValue("@Start", StartTime);
            sqlComm.Parameters.AddWithValue("@Finish", FinishTime);
            sqlComm.Parameters.AddWithValue("@TimeRange", TimeRange);

            sqlComm.CommandType = CommandType.StoredProcedure;

            SqlDataAdapter da = new SqlDataAdapter();
            da.SelectCommand = sqlComm;

            da.Fill(ds);
     }

Looks like the default easy_install is broken in its current location:

$ which easy_install /usr/bin/easy_install

A way to overcome this is to use the easy_install in site packages. For example:

$ sudo python /Library/Python/2.7/site-packages/easy_install.py boto

Its given on OFFICIAL MYSQL website.

SET GLOBAL general_log = 'ON';

You can also use custom path:

[mysqld]
# Set Slow Query Log
long_query_time = 1
slow_query_log = 1
slow_query_log_file = "C:/slowquery.log"

#Set General Log
log = "C:/genquery.log"

Another report here: It didn't work as I exported:

export default compose(
  injectIntl,
  connect(mapStateToProps)(Onboarding)
);

instead of

export default compose(
  injectIntl,
  connect(mapStateToProps)
)(Onboarding);

Note the position of the brackets. Both are correct and won't get caught by either a linter or prettier or something similar. Took me a while to track it down.

My solution was to extend the ProgressDialog class to get my own MyProgressDialog.

I redefined show() and dismiss() methods to lock the orientation before showing the Dialog and unlock it back when Dialog is dismissed.

So when the Dialog is shown and the orientation of the device changes, the orientation of the screen remains until dismiss() is called, then screen-orientation changes according to sensor-values/device-orientation.

Here is my code:

public class MyProgressDialog extends ProgressDialog {
    private Context mContext;

    public MyProgressDialog(Context context) {
        super(context);
        mContext = context;
    }

    public MyProgressDialog(Context context, int theme) {
        super(context, theme);
        mContext = context;
    }
    
    public void show() {
        if (mContext.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT)
            ((Activity) mContext).setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        else
            ((Activity) mContext).setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        super.show();
    }
    
    public void dismiss() {
        super.dismiss();
        ((Activity) mContext).setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
    }
}

$ git rev-parse --abbrev-ref HEAD
master

This should work with Git 1.6.3 or newer.

You can use:

<head>
  <meta name="viewport" content="target-densitydpi=device-dpi, initial-scale=1.0, user-scalable=no" />
  ...
</head>

But please note that with Android 4.4 the property target-densitydpi is no longer supported. So for Android 4.4 and later the following is suggested as best practice:

<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no" />

If you're downloading from somewhere else than your own registry or docker-hub, you might have to do a separate agreement of terms on their site, like the case with Oracle's docker registry. It allows you to do docker login fine, but pulling the container won't still work until you go to their site and agree on their terms.

This worked for me, use the VM args in NetBeans:

@Value("${a.b.c:#{abc}}"
...

@Value("${e.f.g:#{efg}}"
...

Netbeans:

-Da.b.c="..." -De.f.g="..."

Properties -> Run -> VM Options -> -De.f.g=efg -Da.b.c=abc

From the commandline

java -jar <yourjar> --Da.b.c="abc" 

Because you are passing a string as the second argument to the date function, which should be an integer.

string date ( string $format [, int $timestamp = time() ] )

Try strtotime which will Parse about any English textual datetime description into a Unix timestamp (integer):

date("d", strtotime($_GET['start_date']));

I hope my script help you.

<i class="mostrar-producto">mostrar...</i>
<div class="producto" style="display:none;position: absolute;">Producto</div>

My script

<script>
$(".mostrar-producto").mouseover(function(){
     $(".producto").fadeIn();
 });

 $(".mostrar-producto").mouseleave(function(){
      $(".producto").fadeOut();
  });
</script>

User can use this

Dim todaysdate As String = String.Format("{0:dd/MM/yyyy}", DateTime.Now)

this will format the date as required whereas user can change the string type dd/MM/yyyy or MM/dd/yyyy or yyyy/MM/dd or even can have this format to get the time from date

yyyy/MM/dd HH:mm:ss 

Stored procedure is the best way to do it. Because Meherzad's solution would work only if the data follows the same order.

If we have a table structure like this

col1 | col2 | col3
-----+------+------
 3   | k    | 7
 5   | d    | 3
 1   | a    | 5
 6   | o    | 2
 2   | 0    | 8

It wont work. SQL Fiddle Demo

Here is a sample procedure code to achieve the same.

delimiter //
CREATE PROCEDURE chainReaction 
(
    in inputNo int
) 
BEGIN 
    declare final_id int default NULL;
    SELECT col3 
    INTO final_id 
    FROM table1
    WHERE col1 = inputNo;
    IF( final_id is not null) THEN
        INSERT INTO results(SELECT col1, col2, col3 FROM table1 WHERE col1 = inputNo);
        CALL chainReaction(final_id);   
    end if;
END//
delimiter ;

call chainReaction(1);
SELECT * FROM results;
DROP TABLE if exists results;

Let us see the difference between the two HTTP authentication using Wireshark (Tool to analyse packets sent or received) .

1. Http Basic Authentication

As soon as the client types in the correct username:password,as requested by the Web-server, the Web-Server checks in the Database if the credentials are correct and gives the access to the resource .

Here is how the packets are sent and received :

In the first packet the Client fill the credentials using the POST method at the resource - lab/webapp/basicauth .In return the server replies back with http response code 200 ok ,i.e, the username:password were correct .

Now , In the Authorization header it shows that it is Basic Authorization followed by some random string .This String is the encoded (Base64) version of the credentials admin:aadd (including colon ) .

2 . Http Digest Authentication(rfc 2069)

So far we have seen that the Basic Authentication sends username:password in plaintext over the network .But the Digest Auth sends a HASH of the Password using Hash algorithm.

Here are packets showing the requests made by the client and response from the server .

As soon as the client types the credentials requested by the server , the Password is converted to a response using an algorithm and then is sent to the server , If the server Database has same response as given by the client the server gives the access to the resource , otherwise a 401 error .

In the above Authorization , the response string is calculated using the values of Username,Realm,Password,http-method,URI and Nonce as shown in the image :

(colons are included)

Hence , we can see that the Digest Authentication is more Secure as it involve Hashing (MD5 encryption) , So the packet sniffer tools cannot sniff the Password although in Basic Auth the exact Password was shown on Wireshark.

You can copy your div like this

$(".package").html($(".button").html())

from sklearn import metrics
import numpy as np
import matplotlib.pyplot as plt

y_true = # true labels
y_probas = # predicted results
fpr, tpr, thresholds = metrics.roc_curve(y_true, y_probas, pos_label=0)

# Print ROC curve
plt.plot(fpr,tpr)
plt.show() 

# Print AUC
auc = np.trapz(tpr,fpr)
print('AUC:', auc)

encodeURIComponent(Your text here);

This will truncate special characters.

I was working also on web scraping project and same issue found, below code applied and it worked nicely. If you are not aware about TLS versions then you can apply all below otherwise you can apply specific.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11;

The Kotlin way

//FileExt.kt

data class ZipIO (val entry: ZipEntry, val output: File)

fun File.unzip(unzipLocationRoot: File? = null) {

    val rootFolder = unzipLocationRoot ?: File(parentFile.absolutePath + File.separator + nameWithoutExtension)
    if (!rootFolder.exists()) {
       rootFolder.mkdirs()
    }

    ZipFile(this).use { zip ->
        zip
        .entries()
        .asSequence()
        .map {
            val outputFile = File(rootFolder.absolutePath + File.separator + it.name)
            ZipIO(it, outputFile)
        }
        .map {
            it.output.parentFile?.run{
                if (!exists()) mkdirs()
            }
            it
        }
        .filter { !it.entry.isDirectory }
        .forEach { (entry, output) ->
            zip.getInputStream(entry).use { input ->
                output.outputStream().use { output ->
                    input.copyTo(output)
                }
            }
        }
    }

}

Usage

val zipFile = File("path_to_your_zip_file")
file.unzip()

See all Available Controller : You can do PHP artisan list to view all commands

For help: PHP artisan help make:controller

php artisan make:controller MyControllerName

The best way is to use different database groups. If you want to keep using the master database as usual ($this->db) just turn off persistent connexion configuration option to your secondary database(s). Only master database should work with persistent connexion :

Master database

$db['default']['hostname'] = "localhost";
$db['default']['username'] = "root";
$db['default']['password'] = "";
$db['default']['database'] = "database_name";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = FALSE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";
$db['default']['swap_pre'] = "";
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

Secondary database (notice pconnect is set to false)

$db['otherdb']['hostname'] = "localhost";
$db['otherdb']['username'] = "root";
$db['otherdb']['password'] = "";
$db['otherdb']['database'] = "other_database_name";
$db['otherdb']['dbdriver'] = "mysql";
$db['otherdb']['dbprefix'] = "";
$db['otherdb']['pconnect'] = FALSE;
$db['otherdb']['db_debug'] = FALSE;
$db['otherdb']['cache_on'] = FALSE;
$db['otherdb']['cachedir'] = "";
$db['otherdb']['char_set'] = "utf8";
$db['otherdb']['dbcollat'] = "utf8_general_ci";
$db['otherdb']['swap_pre'] = "";
$db['otherdb']['autoinit'] = TRUE;
$db['otherdb']['stricton'] = FALSE;

Then you can use secondary databases as database objects while using master database as usual :

// use master dataabse
$users = $this->db->get('users');

// connect to secondary database
$otherdb = $this->load->database('otherdb', TRUE);
$stuff = $otherdb->get('struff');
$otherdb->insert_batch('users', $users->result_array());

// keep using master database as usual, for example insert stuff from other database
$this->db->insert_batch('stuff', $stuff->result_array());

If you're already running a php page then

php bit:

    $json   =   json_encode($_REQUEST, JSON_FORCE_OBJECT);
    print "<script>var getVars = $json;</script>";

js bit:

    var param1var = getVars.param1var;

But for Html pages Jose Basilio's solution looks good to me.

Good luck!

I recommend you just use rubyinstaller

It is recommended by the official Ruby page - see https://www.ruby-lang.org/en/downloads/

Ways of Installing Ruby

We have several tools on each major platform to install Ruby:

• On Linux/UNIX, you can use the package management system of your distribution or third-party tools (rbenv and RVM).
• On OS X machines, you can use third-party tools (rbenv and RVM).
• On Windows machines, you can use RubyInstaller.

Based on the answer from #squiguy, to get a true timestamp I would type cast it from float.

>>> import time
>>> ts = int(time.time())
>>> print(ts)
1389177318

At least that's the concept.

What am I doing incorrectly?

You have to convert html to javascript object, and then as a second step to json throug JSON.Stringify.

How can I receive a json object in the controller?

View:

<script src="https://code.jquery.com/jquery-3.1.0.js"></script>
<script src="https://raw.githubusercontent.com/marioizquierdo/jquery.serializeJSON/master/jquery.serializejson.js"></script>

var obj = $("#form1").serializeJSON({ useIntKeysAsArrayIndex: true });
$.post("http://localhost:52161/Default/PostRawJson/", { json: JSON.stringify(obj) });

There are JDK versions available from the base CentOS repositories. Depending on your version of CentOS, and the JDK you want to install, the following as root should give you what you want:

OpenJDK Runtime Environment (Java SE 6)

yum install java-1.6.0-openjdk

OpenJDK Runtime Environment (Java SE 7)

yum install java-1.7.0-openjdk

OpenJDK Development Environment (Java SE 7)

yum install java-1.7.0-openjdk-devel

OpenJDK Development Environment (Java SE 6)

yum install java-1.6.0-openjdk-devel

Update for Java 8

In CentOS 6.6 or later, Java 8 is available. Similar to 6 and 7 above, the packages are as follows:

OpenJDK Runtime Environment (Java SE 8)

yum install java-1.8.0-openjdk

OpenJDK Development Environment (Java SE 8)

yum install java-1.8.0-openjdk-devel

There's also a 'headless' JRE package that is the same as the above JRE, except it doesn't contain audio/video support. This can be used for a slightly more minimal installation:

OpenJDK Runtime Environment - Headless (Java SE 8)

yum install java-1.8.0-openjdk-headless

Please also make sure that the modal div is nested inside your <body> element.

try this:

word-break: break-all;

As you can see here:

html5 oninvalid doesn't work after fixed the input field

Is good to you put in that way, for when you fix the error disapear the warning message.

<input type="text" pattern="[a-zA-Z]+"
oninvalid="this.setCustomValidity(this.willValidate?'':'your custom message')" />

The Docker V2 API requires an OAuth bearer token with the appropriate claims. In my opinion, the official documentation is rather vague on the topic. So that others don't go through the same pain I did, I offer the below docker-tags function.

The most recent version of docker-tags can be found in my GitHubGist : "List Docker Image Tags using bash".

The docker-tags function has a dependency on jq. If you're playing with JSON, you likely already have it.

#!/usr/bin/env bash
docker-tags() {
    arr=("$@")

    for item in "${arr[@]}";
    do
        tokenUri="https://auth.docker.io/token"
        data=("service=registry.docker.io" "scope=repository:$item:pull")
        token="$(curl --silent --get --data-urlencode ${data[0]} --data-urlencode ${data[1]} $tokenUri | jq --raw-output '.token')"
        listUri="https://registry-1.docker.io/v2/$item/tags/list"
        authz="Authorization: Bearer $token"
        result="$(curl --silent --get -H "Accept: application/json" -H "Authorization: Bearer $token" $listUri | jq --raw-output '.')"
        echo $result
    done
}

Example

docker-tags "microsoft/nanoserver" "microsoft/dotnet" "library/mongo" "library/redis"

Admittedly, docker-tags makes several assumptions. Specifically, the OAuth request parameters are mostly hard coded. A more ambitious implementation would make an unauthenticated request to the registry and derive the OAuth parameters from the unauthenticated response.

I have found that the following works well in 2.7.x

import os
two_up = os.path.normpath(os.path.join(__file__,'../'))

String query="select * from test1 where "+selected+" like '%"+SelectedStr+"%';";


PreparedStatement preparedStatement=con.prepareStatement(query);


// where seleced and SelectedStr are String Variables in my program

Use this syntax for VB.NET 2005/2008 compatibility:

Dim theVar As New List(Of String)(New String() {"one", "two", "three"})

Although the VB.NET 2010 syntax is prettier.

A little late to the party, but this worked for me. Hopefully someone else finds it useful.

<div ng-repeat="video in videos" ng-if="$index < 3">
    ...
</div>

I came up with a very effective, (I think) readable way to do this.

    1. create a temp table and put the records you want to iterate in there
    2. use WHILE @@ROWCOUNT <> 0 to do the iterating
    3. to get one row at a time do, SELECT TOP 1 <fieldnames>
        b. save the unique ID for that row in a variable
    4. Do Stuff, then delete the row from the temp table based on the ID saved at step 3b.

Here's the code. Sorry, its using my variable names instead of the ones in the question.

            declare @tempPFRunStops TABLE (ProformaRunStopsID int,ProformaRunMasterID int, CompanyLocationID int, StopSequence int );    

        INSERT @tempPFRunStops (ProformaRunStopsID,ProformaRunMasterID, CompanyLocationID, StopSequence) 
        SELECT ProformaRunStopsID, ProformaRunMasterID, CompanyLocationID, StopSequence from ProformaRunStops 
        WHERE ProformaRunMasterID IN ( SELECT ProformaRunMasterID FROM ProformaRunMaster WHERE ProformaId = 15 )

    -- SELECT * FROM @tempPFRunStops

    WHILE @@ROWCOUNT <> 0  -- << I dont know how this works
        BEGIN
            SELECT TOP 1 * FROM @tempPFRunStops
            -- I could have put the unique ID into a variable here
            SELECT 'Ha'  -- Do Stuff
            DELETE @tempPFRunStops WHERE ProformaRunStopsID = (SELECT TOP 1 ProformaRunStopsID FROM @tempPFRunStops)
        END

Use unlist with use.names = FALSE argument.

unlist(myList, use.names=FALSE)

Use Pypdf or its successor PyPDF2:

A Pure-Python library built as a PDF toolkit. It is capable of:
* splitting documents page by page,
* merging documents page by page,

(and much more)

Here's a sample program that works with both versions.

#!/usr/bin/env python
import sys
try:
    from PyPDF2 import PdfFileReader, PdfFileWriter
except ImportError:
    from pyPdf import PdfFileReader, PdfFileWriter

def pdf_cat(input_files, output_stream):
    input_streams = []
    try:
        # First open all the files, then produce the output file, and
        # finally close the input files. This is necessary because
        # the data isn't read from the input files until the write
        # operation. Thanks to
        # https://stackoverflow.com/questions/6773631/problem-with-closing-python-pypdf-writing-getting-a-valueerror-i-o-operation/6773733#6773733
        for input_file in input_files:
            input_streams.append(open(input_file, 'rb'))
        writer = PdfFileWriter()
        for reader in map(PdfFileReader, input_streams):
            for n in range(reader.getNumPages()):
                writer.addPage(reader.getPage(n))
        writer.write(output_stream)
    finally:
        for f in input_streams:
            f.close()

if __name__ == '__main__':
    if sys.platform == "win32":
        import os, msvcrt
        msvcrt.setmode(sys.stdout.fileno(), os.O_BINARY)
    pdf_cat(sys.argv[1:], sys.stdout)

On top of what the others have already stated, some sort of server-side scripting is necessary in order for the server to read and save the file.

Using PHP might be a good choice, but you're free to use any server-side scripting language. http://www.w3schools.com/php/php_file_upload.asp may be of use on that end.

I think is more robust to use regular expressions:

import re

for i, line in enumerate(content):
    print line if not (re.match('\r?\n', line)) else pass

This would match in Windows/unix. In addition if you are not sure about lines containing only space char you could use '\s*\r?\n' as expression

Handles either type of line break

str.replace(new RegExp('\r?\n','g'), '<br />');

I hope that you will find helpfull the following trick.

You can bind both the events

combobox.SelectionChanged += OnSelectionChanged;
combobox.DropDownOpened += OnDropDownOpened;

And force selected item to null inside the OnDropDownOpened

private void OnDropDownOpened(object sender, EventArgs e)
{
    combobox.SelectedItem = null;
}

And do what you need with the item inside the OnSelectionChanged. The OnSelectionChanged will be raised every time you will open the combobox, but you can check if SelectedItem is null inside the method and skip the command

private void OnSelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        if (combobox.SelectedItem != null)
        {
           //Do something with the selected item
        }
    }

UPDATE Orders Order
SET Order.Quantity =  Order.Quantity - 1
WHERE SomeCondition(Order)

As far as I know there is no build-in support for INSERT-OR-UPDATE in SQL. I suggest to create a stored procedure or use a conditional query to achiev this. Here you can find a collection of solutions for different databases.

If you are using any IDE most likely the problem is that file was used by some process. Like your tomcat might be using the file. Try to identify that particular process and close it. That should solve your problem.

Where is this info kept ("this connection is between computer A and server F")?

A TCP connection is recognized by source IP and port and destination IP and port. Your OS, all intermediate session-aware devices and the server's OS will recognize the connection by this.

HTTP works with request-response: client connects to server, performs a request and gets a response. Without keep-alive, the connection to an HTTP server is closed after each response. With HTTP keep-alive you keep the underlying TCP connection open until certain criteria are met.

This allows for multiple request-response pairs over a single TCP connection, eliminating some of TCP's relatively slow connection startup.

When The IIS (F) sends keep alive header (or user sends keep-alive) , does it mean that (E,C,B) save a connection

No. Routers don't need to remember sessions. In fact, multiple TCP packets belonging to same TCP session need not all go through same routers - that is for TCP to manage. Routers just choose the best IP path and forward packets. Keep-alive is only for client, server and any other intermediate session-aware devices.

which is only for my session ?

Does it mean that no one else can use that connection

That is the intention of TCP connections: it is an end-to-end connection intended for only those two parties.

If so - does it mean that keep alive-header - reduce the number of overlapped connection users ?

Define "overlapped connections". See HTTP persistent connection for some advantages and disadvantages, such as:

• Lower CPU and memory usage (because fewer connections are open simultaneously).
• Enables HTTP pipelining of requests and responses.
• Reduced network congestion (fewer TCP connections).
• Reduced latency in subsequent requests (no handshaking).

if so , for how long does the connection is saved to me ? (in other words , if I set keep alive- "keep" till when?)

An typical keep-alive response looks like this:

Keep-Alive: timeout=15, max=100

See Hypertext Transfer Protocol (HTTP) Keep-Alive Header for example (a draft for HTTP/2 where the keep-alive header is explained in greater detail than both 2616 and 2086):

• A host sets the value of the timeout parameter to the time that the host will allows an idle connection to remain open before it is closed. A connection is idle if no data is sent or received by a host.

• The max parameter indicates the maximum number of requests that a client will make, or that a server will allow to be made on the persistent connection. Once the specified number of requests and responses have been sent, the host that included the parameter could close the connection.

However, the server is free to close the connection after an arbitrary time or number of requests (just as long as it returns the response to the current request). How this is implemented depends on your HTTP server.

This function will return a converted SQL date from java date object.

public static java.sql.Date convertFromJAVADateToSQLDate(
            java.util.Date javaDate) {
        java.sql.Date sqlDate = null;
        if (javaDate != null) {
            sqlDate = new Date(javaDate.getTime());
        }
        return sqlDate;
    }

The usual cause of this is that you're also using Prototype, MooTools, or some other library that makes use of the $ symbol, and you're including that library after jQuery, and so that library is "winning" (taking $ for itself). So the return value of $ isn't a jQuery instance, and so it doesn't have jQuery methods on it (like on).

You can use jQuery with those other libraries, but if you do, you have to use the jQuery symbol rather than its alias $, e.g.:

jQuery('body').on(...);

And it's usually best if you add this immediately after your script tag including jQuery, before the one including the other library:

<script>jQuery.noConflict();</script>

...although it's not required if you load the other library after jQuery (it is if you load the other library first).

Using multiple full-function DOM manipulation libraries on the same page isn't ideal, though, just in terms of page weight. So if you can stick with just Prototype/MooTools/whatever or just jQuery, that's usually better.

A void* pointer is used when you want to indicate a pointer to a hunk of memory without specifying the type. C's malloc returns such a pointer, expecting you to cast it to a particular type immediately. It really isn't useful until you cast it to another pointer type. You're expected to know which type to cast it to, the compiler has no reflection capability to know what the underlying type should be.

Jasmine doesn't have that functionality, but you might be able to hack something together using Object.defineProperty.

You could refactor your code to use a getter function, then spy on the getter.

spyOn(myObj, 'getValueA').andReturn(1);
expect(myObj.getValueA()).toBe(1);

By default Spring Security redirects user to the URL that he originally requested (/Load.do in your case) after login.

You can set always-use-default-target to true to disable this behavior:

 <security:http auto-config="true">

    <security:intercept-url pattern="/Admin**" access="hasRole('PROGRAMMER') or hasRole('ADMIN')"/>
    <security:form-login login-page="/Load.do"
        default-target-url="/Admin.do?m=loadAdminMain"
        authentication-failure-url="/Load.do?error=true"
        always-use-default-target = "true"
        username-parameter="j_username"
        password-parameter="j_password"
        login-processing-url="/j_spring_security_check"/>
    <security:csrf/><!-- enable Cross Site Request Forgery protection -->
</security:http>

Use Object#toString().

String string = map.toString();

That's after all also what System.out.println(object) does under the hoods. The format for maps is described in AbstractMap#toString().

Returns a string representation of this map. The string representation consists of a list of key-value mappings in the order returned by the map's entrySet view's iterator, enclosed in braces ("{}"). Adjacent mappings are separated by the characters ", " (comma and space). Each key-value mapping is rendered as the key followed by an equals sign ("=") followed by the associated value. Keys and values are converted to strings as by String.valueOf(Object).

You can try to use the following code instead:

 $pro= model_name::where('col_name', '=', 'value')->get();

Some time this error in Joomla appear because some thing incorrect with SESSION or coockie. That may because incorrect HTTPd server setting or because some before CURL or Server http requests

so PHP code like:

  curl_setopt($ch, CURLOPT_URL, $url_page);
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
  curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
  curl_setopt($ch, CURLOPT_REFERER, $url_page);
  curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
  curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__) . "./cookie.txt");
  curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . "./cookie.txt");
  curl_setopt($ch, CURLOPT_COOKIE, session_name() . '=' . session_id());

  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
  if( $sc != "" ) curl_setopt($ch, CURLOPT_COOKIE, $sc);

will need replace to PHP code

  curl_setopt($ch, CURLOPT_URL, $url_page);
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
//curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
  curl_setopt($ch, CURLOPT_REFERER, $url_page);
  curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
//curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__) . "./cookie.txt");
//curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . "./cookie.txt");
//curl_setopt($ch, CURLOPT_COOKIE, session_name() . '=' . session_id());

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false); // !!!!!!!!!!!!!
  //if( $sc != "" ) curl_setopt($ch, CURLOPT_COOKIE, $sc);

May be some body reply how this options connected with "Curl error: Operation timed out after .."

This didn't start happening for me until I rooted my Samsung Galaxy S III phone (following the xda-developer forum guide).

It happens pretty randomly, but it's definitely occurring while running Eclipse.

Killing the adb.exe process and restarting it solves the problem.

I am able to download it using apple's download website today. https://developer.apple.com/download/

I do not have a paid apple developer account. Before I was only able to see xcode 8.3.3 but somehow today xcode 9 beta also appeared.

You just need to check whether the file is there, by typing

cat /etc/apache2/mods-available/rewrite.load

The result line may not be commented starting with #

var url ='www.site.com/index.php#hello';
var type = url.split('#');
var hash = '';
if(type.length > 1)
  hash = type[1];
alert(hash);

Send the signal to all the processes in group

Let's say you have 2 csv files like these:

csv1.csv:

id,name
1,Armin
2,Sven

csv2.csv:

id,place,year
1,Reykjavik,2017
2,Amsterdam,2018
3,Berlin,2019

and you want the result to be like this csv3.csv:

id,name,place,year
1,Armin,Reykjavik,2017
2,Sven,Amsterdam,2018
3,,Berlin,2019

Then you can use the following snippet to do that:

import csv
import pandas as pd

# the file names
f1 = "csv1.csv"
f2 = "csv2.csv"
out_f = "csv3.csv"

# read the files
df1 = pd.read_csv(f1)
df2 = pd.read_csv(f2)

# get the keys
keys1 = list(df1)
keys2 = list(df2)

# merge both files
for idx, row in df2.iterrows():
    data = df1[df1['id'] == row['id']]

    # if row with such id does not exist, add the whole row
    if data.empty:
        next_idx = len(df1)
        for key in keys2:
            df1.at[next_idx, key] = df2.at[idx, key]

    # if row with such id exists, add only the missing keys with their values
    else:
        i = int(data.index[0])
        for key in keys2:
            if key not in keys1:
                df1.at[i, key] = df2.at[idx, key]

# save the merged files
df1.to_csv(out_f, index=False, encoding='utf-8', quotechar="", quoting=csv.QUOTE_NONE)

With the help of a loop you can achieve the same result for multiple files as it is in your case (200 csv files).

I would just recommend creating a new virtual environment and installing all the packages from the start as the wheels for some packages might have been installed for the previous version of the Python. I believe this is the safest way and you have two options.

1. Creating a new virtual environment with venv:

   python3.6 -m venv -n new_env
   source venv_env/bin/activate
   

2. Creating a conda environment:

   conda create -n new_env python=3.6
   conda activate new_env
   

The packages you install in an environment are built based on the Python version of the environment and if you do not carefully modify the existing environment, then, you can cause some incompatibilities between packages. That is why I would recommend a using a new environment built with Python 3.6.

It's all about the ease of use/steps required to do something.

If I'm developing a single project on my PC/laptop, git is better, because it is far easier to set up and use. You don't need a server, and you don't need to keep typing repository URL's in when you do merges.

If it were just 2 people, I'd say git is also easier, because you can just push and pull from eachother.

Once you get beyond that though, I'd go for subversion, because at that point you need to set up a 'dedicated' server or location.

You can do this just as well with git as with SVN, but the benefits of git get outweighed by the need to do additional steps to synch with a central server. In SVN you just commit. In git you have to git commit, then git push. The additional step gets annoying simply because you end up doing it so much.

SVN also has the benefit of better GUI tools, however the git ecosystem seems to be catching up quickly, so I wouldn't worry about this in the long term.

Yes. std::exception is the base exception class in the C++ standard library. You may want to avoid using strings as exception classes because they themselves can throw an exception during use. If that happens, then where will you be?

boost has an excellent document on good style for exceptions and error handling. It's worth a read.

You should use maven surefire plugin to run unit tests and maven failsafe plugin to run integration tests.

Please follow below if you wish to toggle the execution of these tests using flags.

            <skipIntegrationTests>${skipTests}</skipIntegrationTests>
        </properties>

So, tests will be skipped or switched according to below flag rules:

Tests can be skipped by below flags:

• -DskipTests skips both unit and integration tests
• -DskipUnitTests skips unit tests but executes integration tests
• -DskipIntegrationTests skips integration tests but executes unit tests

Running Tests

Run below to execute only Unit Tests

mvn clean test

You can execute below command to run the tests (both unit and integration)

mvn clean verify

In order to run only Integration Tests, follow

mvn failsafe:integration-test

Or skip unit tests

mvn clean install -DskipUnitTests

Also, in order to skip integration tests during mvn install, follow

mvn clean install -DskipIntegrationTests

You can skip all tests using

mvn clean install -DskipTests

I don't know about determining height just now, but you can use this to put something on the bottom:

<html>
<head>
<title>CSS bottom test</title>
<style>
.bottom {
  position: absolute;
  bottom: 1em;
  left: 1em;
}
</style>
</head>

<body>

<p>regular body stuff.</p>

<div class='bottom'>on the bottom</div>

</body>
</html>

Another way is to simply pass the json string as a dict to the constructor of your object. For example your object is:

class Payload(object):
    def __init__(self, action, method, data, *args, **kwargs):
        self.action = action
        self.method = method
        self.data = data

And the following two lines of python code will construct it:

j = json.loads(yourJsonString)
payload = Payload(**j)

Basically, we first create a generic json object from the json string. Then, we pass the generic json object as a dict to the constructor of the Payload class. The constructor of Payload class interprets the dict as keyword arguments and sets all the appropriate fields.

I tried to add another join(), and it seems worked. Here is code

from threading import Thread
from time import sleep

def function01(arg,name):
    for i in range(arg):
        print(name,'i---->',i,'\n')
        print (name,"arg---->",arg,'\n')
        sleep(1)

def test01():
    thread1 = Thread(target = function01, args = (10,'thread1', ))
    thread1.start()
    thread2 = Thread(target = function01, args = (10,'thread2', ))
    thread2.start()
    thread1.join()
    thread2.join()
    print ("thread finished...exiting")

test01()

I think the problem was the two single quotes missing.

This is the sql I run to the MSSMS:

WHERE checktime >= '2019-01-24 15:01:36.000' AND checktime <= '2019-01-25 16:01:36.000'

As you can see there are two single quotes, so your codes must be:

string sqlFormattedDate = "'" + myDateTime.Date.ToString("yyyy-MM-dd") + " " + myDateTime.TimeOfDay.ToString("HH:mm:ss") + "'";

Use single quotes for every string in MSSQL or even in MySQL. I hope this helps.

There is one more solution to set column Full text to true.

These solution for example didn't work for me

ALTER TABLE news ADD FULLTEXT(headline, story);

My solution.

1. Right click on table
2. Design
3. Right Click on column which you want to edit
4. Full text index
5. Add
6. Close
7. Refresh

NEXT STEPS

1. Right click on table
2. Design
3. Click on column which you want to edit
4. On bottom of mssql you there will be tab "Column properties"
5. Full-text Specification -> (Is Full-text Indexed) set to true.

Refresh

The spring docs are great on this: 3.8.1. BeanFactory or ApplicationContext?. They have a table with a comparison, I'll post a snippet:

Bean Factory

• Bean instantiation/wiring

Application Context

• Bean instantiation/wiring
• Automatic BeanPostProcessor registration
• Automatic BeanFactoryPostProcessor registration
• Convenient MessageSource access (for i18n)
• ApplicationEvent publication

So if you need any of the points presented on the Application Context side, you should use ApplicationContext.

You will have to use the fluent API to do this.

Try adding the following to your DbContext:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{   
    modelBuilder.Entity<User>()
        .HasOptional(a => a.UserDetail)
        .WithOptionalDependent()
        .WillCascadeOnDelete(true);
}

When you checkout to a commit git checkout <commit-hash> or to a remote branch your HEAD will get detached and try to create a new commit on it.

Commits that are not reachable by any branch or tag will be garbage collected and removed from the repository after 30 days.

Another way to solve this is by creating a new branch for the newly created commit and checkout to it. git checkout -b <branch-name> <commit-hash>

This article illustrates how you can get to detached HEAD state.

Deleting Obj, retail and debug folder of the .NET project and re-building again worked for me.

Look here for details.

private PerformanceCounter cpuCounter;
private PerformanceCounter ramCounter;
public Form1()
{
    InitializeComponent();
    InitialiseCPUCounter();
    InitializeRAMCounter();
    updateTimer.Start();
}

private void updateTimer_Tick(object sender, EventArgs e)
{
    this.textBox1.Text = "CPU Usage: " +
    Convert.ToInt32(cpuCounter.NextValue()).ToString() +
    "%";

    this.textBox2.Text = Convert.ToInt32(ramCounter.NextValue()).ToString()+"Mb";
}

private void Form1_Load(object sender, EventArgs e)
{
}

private void InitialiseCPUCounter()
{
    cpuCounter = new PerformanceCounter(
    "Processor",
    "% Processor Time",
    "_Total",
    true
    );
}

private void InitializeRAMCounter()
{
    ramCounter = new PerformanceCounter("Memory", "Available MBytes", true);

}

If you get value as 0 it need to call NextValue() twice. Then it gives the actual value of CPU usage. See more details here.

The problem with toISOString is that it gives datetime only as "Z".

ISO-8601 also defines datetime with timezone difference in hours and minutes, in the forms like 2016-07-16T19:20:30+5:30 (when timezone is ahead UTC) and 2016-07-16T19:20:30-01:00 (when timezone is behind UTC).

I don't think it is a good idea to use another plugin, moment.js for such a small task, especially when you can get it with a few lines of code.

    var timezone_offset_min = new Date().getTimezoneOffset(),
        offset_hrs = parseInt(Math.abs(timezone_offset_min/60)),
        offset_min = Math.abs(timezone_offset_min%60),
        timezone_standard;

    if(offset_hrs < 10)
        offset_hrs = '0' + offset_hrs;

    if(offset_min > 10)
        offset_min = '0' + offset_min;

    // getTimezoneOffset returns an offset which is positive if the local timezone is behind UTC and vice-versa.
    // So add an opposite sign to the offset
    // If offset is 0, it means timezone is UTC
    if(timezone_offset_min < 0)
        timezone_standard = '+' + offset_hrs + ':' + offset_min;
    else if(timezone_offset_min > 0)
        timezone_standard = '-' + offset_hrs + ':' + offset_min;
    else if(timezone_offset_min == 0)
        timezone_standard = 'Z';

    // Timezone difference in hours and minutes
    // String such as +5:30 or -6:00 or Z
    console.log(timezone_standard); 

Once you have the timezone offset in hours and minutes, you can append to a datetime string.

I wrote a blog post on it : http://usefulangle.com/post/30/javascript-get-date-time-with-offset-hours-minutes

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

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

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

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

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

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

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

You could have the CSS first style the textbox, then have js change it:

<input type="text" style="background-color: yellow;" id="subEmail" />

js:

function changeColor() {
  document.getElementById("subEmail").style.backgroundColor = "Insert color here"
}

Let me answer your 3rd question first:

If you want to run a self-compiled version within a conda-env, you can. These are the general instructions I run to get tensorflow to install on my system with additional instructions. Note: This build was for an AMD A10-7850 build (check your CPU for what instructions are supported...it may differ) running Ubuntu 16.04 LTS. I use Python 3.5 within my conda-env. Credit goes to the tensorflow source install page and the answers provided above.

git clone https://github.com/tensorflow/tensorflow 
# Install Bazel
# https://bazel.build/versions/master/docs/install.html
sudo apt-get install python3-numpy python3-dev python3-pip python3-wheel
# Create your virtual env with conda.
source activate YOUR_ENV
pip install six numpy wheel, packaging, appdir
# Follow the configure instructions at:
# https://www.tensorflow.org/install/install_sources
# Build your build like below. Note: Check what instructions your CPU 
# support. Also. If resources are limited consider adding the following 
# tag --local_resources 2048,.5,1.0 . This will limit how much ram many
# local resources are used but will increase time to compile.
bazel build -c opt --copt=-mavx --copt=-msse4.1 --copt=-msse4.2  -k //tensorflow/tools/pip_package:build_pip_package
# Create the wheel like so:
bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
# Inside your conda env:
pip install /tmp/tensorflow_pkg/NAME_OF_WHEEL.whl
# Then install the rest of your stack
pip install keras jupyter etc. etc.

As to your 2nd question:

A self-compiled version with optimizations are well worth the effort in my opinion. On my particular setup, calculations that used to take 560-600 seconds now only take about 300 seconds! Although the exact numbers will vary, I think you can expect about a 35-50% speed increase in general on your particular setup.

Lastly your 1st question:

A lot of the answers have been provided above already. To summarize: AVX, SSE4.1, SSE4.2, MFA are different kinds of extended instruction sets on X86 CPUs. Many contain optimized instructions for processing matrix or vector operations.

I will highlight my own misconception to hopefully save you some time: It's not that SSE4.2 is a newer version of instructions superseding SSE4.1. SSE4 = SSE4.1 (a set of 47 instructions) + SSE4.2 (a set of 7 instructions).

In the context of tensorflow compilation, if you computer supports AVX2 and AVX, and SSE4.1 and SSE4.2, you should put those optimizing flags in for all. Don't do like I did and just go with SSE4.2 thinking that it's newer and should superseed SSE4.1. That's clearly WRONG! I had to recompile because of that which cost me a good 40 minutes.

pod deintegrate and pod clean are two designated commands to remove CocoaPod from your project/repo.

Here is the complete set of commands:

$ sudo gem install cocoapods-deintegrate cocoapods-clean
$ pod deintegrate
$ pod cache clean --all
$ rm Podfile

We can do this sort of thing with the advent of the format method since python2.6:

>>> import datetime
>>> '{dt.year}/{dt.month}/{dt.day}'.format(dt = datetime.datetime.now())
'2013/4/19'

Though perhaps beyond the scope of the original question, for more interesting formats, you can do stuff like:

>>> '{dt:%A} {dt:%B} {dt.day}, {dt.year}'.format(dt=datetime.datetime.now())
'Wednesday December 3, 2014'

And as of python3.6, this can be expressed as an inline formatted string:

Python 3.6.0a2 (v3.6.0a2:378893423552, Jun 13 2016, 14:44:21) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import datetime
>>> dt = datetime.datetime.now()
>>> f'{dt:%A} {dt:%B} {dt.day}, {dt.year}'

As stated multiple times, inversion is achieved by the -v option to grep. Let me add the (hopefully amusing) note that you could have figured this out yourself by grepping through the grep help text:

grep --help | grep invert

-v, --invert-match select non-matching lines

use this filter:

(dns.flags.response == 0) and (ip.src == 159.25.78.7)

what this query does is it only gives dns queries originated from your ip

Some important facts were not given in other answers:

"async await" is more complex at CIL level and thus costs memory and CPU time.

Any task can be canceled if the waiting time is unacceptable.

In the case "async await" we do not have a handler for such a task to cancel it or monitoring it.

Using Task is more flexible then "async await".

Any sync functionality can by wrapped by async.

public async Task<ActionResult> DoAsync(long id) 
{ 
    return await Task.Run(() => { return DoSync(id); } ); 
} 

"async await" generate many problems. We do not now is await statement will be reached without runtime and context debugging. If first await not reached everything is blocked. Some times even await seems to be reached still everything is blocked:

https://github.com/dotnet/runtime/issues/36063

I do not see why I'm must live with the code duplication for sync and async method or using hacks.

Conclusion: Create Task manually and control them is much better. Handler to Task give more control. We can monitor Tasks and manage them:

Sorry for my english.

A quick fix is to add the _CRT_SECURE_NO_WARNINGS definition to your project's settings

Right-click your C++ and chose the "Properties" item to get to the properties window.

Now follow and expand to, "Configuration Properties"->"C/C++"->"Preprocessor"->"Preprocessor definitions".

In the "Preprocessor definitions" add

_CRT_SECURE_NO_WARNINGS

but it would be a good idea to add

_CRT_SECURE_NO_WARNINGS;%(PreprocessorDefinitions)

as to inherit predefined definitions

IMHO & for the most part this is a good approach.

In my case it was a copy/paste problem. I somehow ended up with a PRIVATE constructor for my mapping profile:

using AutoMapper;

namespace Your.Namespace
{
    public class MappingProfile : Profile
    {
        MappingProfile()
        {
            CreateMap<Animal, AnimalDto>();
        }
    }
}

(take note of the missing "public" in front of the ctor)

which compiled perfectly fine, but when AutoMapper tries to instantiate the profile it can't (of course!) find the constructor!

It's all about trying all those answers, for me, nothing works except the next solution: Google font suggested

@import 'https://fonts.googleapis.com/css?family=Assistant';

But, I'm using here foreign language fonts, and it didn't work on IE11 only. I found out this solution that worked:

@import 'https://fonts.googleapis.com/css?family=Assistant&subset=hebrew';

Hope that save someone precious time

Stringifying a null value in ActionScript will give the string "NULL". My suspicion is that someone has decided that it is, therefore, a good idea to decode the string "NULL" as null, causing the breakage you see here -- probably because they were passing in null objects and getting strings in the database, when they didn't want that (so be sure to check for that kind of bug, too).

My machine is Windows 10, I've faced similar problems while tried to compile SASS using node-sass package. My node version is v10.16.3 and npm version is 6.9.0

The way that I resolved the problem:

1. At first delete package-lock.json file and node_modules/ folder.
2. Open Windows PowerShell as Administrator.
3. Run the command npm i -g node-sass.
4. After that, go to the project folder and run npm install
5. And finally, run the SASS compiling script, in my case, it is npm run build:css

And it works!!

Is this what you are looking for?

Option Explicit

Public Sub addDataToTable(ByVal strTableName As String, ByVal strData As String, ByVal col As Integer)
    Dim lLastRow As Long
    Dim iHeader As Integer

    With ActiveSheet.ListObjects(strTableName)
        'find the last row of the list
        lLastRow = ActiveSheet.ListObjects(strTableName).ListRows.Count
        'shift from an extra row if list has header
        If .Sort.Header = xlYes Then
            iHeader = 1
        Else
            iHeader = 0
        End If
    End With
    'add the data a row after the end of the list
    ActiveSheet.Cells(lLastRow + 1 + iHeader, col).Value = strData
End Sub

It handles both cases whether you have header or not.

Here is another way you can change the selected option of a <select> element in javascript. You can use

document.getElementById('salesperson').selectedIndex=1;

Setting it to 1 will make the second element of the dropdown selected. The select element index start from 0.

Here is a sample code. Check if you can use this type of approach:

<html>
<head>
<script language="javascript">

function changeSelected() { 
document.getElementById('salesperson').selectedIndex=1;

} 

</script>
</head>
<body>
<form name="f1">

<select id="salesperson" > 
   <option value"">james</option>
   <option value"">john</option>  
</select> 
<input type="button" value="Change Selected" onClick="changeSelected();">

</form>
</body>
</html>

I believe because cases must be constant values, the switch statement does the equivelent of a goto, so based on the value of the variable it jumps to the right case, whereas in the if/then statement it must evaluate each expression.

This should be quite simple with something like this :

public static String toBinary(int number){
    StringBuilder sb = new StringBuilder();

    if(number == 0)
        return "0";
    while(number>=1){
        sb.append(number%2);
        number = number / 2;
    }

    return sb.reverse().toString();

}

Another way to do this solely with css:

input[type='checkbox'] {
  float: left;
  width: 20px;
}
input[type='checkbox'] + label {
  display: block;
  width: 30px;
}

Note that this forces each checkbox and its label onto a separate line, rather than only doing so only when there's overflow.

Regarding Wolfwyrd's anwer: "On Error Resume Next" in fact turns error handling off! Not on. On Error Goto 0 turns error-handling back ON because at the least, we want the machine to catch it if we didn't write it in ourselves. Off = leaving it to you to handle it.

If you use On Error Resume Next, you need to be careful about how much code you include after it: remember, the phrase "If Err.Number <> 0 Then" only refers to the most previous error triggered.

If your block of code after "On Error Resume Next" has several places where you might reasonably expect it to fail, then you must place "If Err.number <> 0" after each and every one of those possible failure lines, to check execution.

Otherwise, after "on error resume next" means just what it says - your code can fail on as many lines as it likes and execution will continue merrily along. That's why it's a pain in the ass.

I used your idea, and found the difference and then just divided by 365 days. Worked a treat.

=MINUS(F2,TODAY())/365

Then I shifted my cell properties to not display decimals.

dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))

na.omit(dat)
  x1  x2
1  1 100
3  3 300
5  5 500

I had the same problem. My project layout looked like

\---super
    \---thirdparty
        +---mod1-root
        |   +---mod1-linux32
        |   \---mod1-win32
        \---mod2-root
            +---mod2-linux32
            \---mod2-win32

In my case, I had a mistake in my pom.xmls at the modX-root-level. I had copied the mod1-root tree and named it mod2-root. I incorrectly thought I had updated all the pom.xmls appropriately; but in fact, mod2-root/pom.xml had the same group and artifact ids as mod1-root/pom.xml. After correcting mod2-root's pom.xml to have mod2-root specific maven coordinates my issue was resolved.

Alan already gave you the right answer - use the sAMAccountName to filter your user.

I would add a recommendation on your use of DirectorySearcher - if you only want one or two pieces of information, add them into the "PropertiesToLoad" collection of the DirectorySearcher.

Instead of retrieving the whole big user object and then picking out one or two items, this will just return exactly those bits you need.

Sample:

adSearch.PropertiesToLoad.Add("sn");  // surname = last name
adSearch.PropertiesToLoad.Add("givenName");  // given (or first) name
adSearch.PropertiesToLoad.Add("mail");  // e-mail addresse
adSearch.PropertiesToLoad.Add("telephoneNumber");  // phone number

Those are just the usual AD/LDAP property names you need to specify.

Math.Pow() returns double so nice would be to write like this:

double d = Math.Pow(100.00, 3.00);

First of all, your selector is overkill. I suggest using a class or ID selector like my example below. Once you've corrected your selector, simply use jQuery's .each() to iterate through the collection:

ID Selector:

$('#mytable td').each(function() {
    var cellText = $(this).html();    
});

Class Selector:

$('.myTableClass td').each(function() {
    var cellText = $(this).html();    
});

Additional Information:

Take a look at jQuery's selector docs.

you need to enable first the App password of your google account -> security section link

then the app password that will be generated copy it and paste it in to .env file

MAIL_DRIVER=smtp
MAIL_HOST=smtp.googlemail.com
MAIL_PORT=465
[email protected]
MAIL_PASSWORD=app_password
MAIL_ENCRYPTION=ssl

At a minimum, change this:

function BlockID() {
    var IDs = new Array();
        images['s'] = "Images/Block_01.png";
        images['g'] = "Images/Block_02.png";
        images['C'] = "Images/Block_03.png";
        images['d'] = "Images/Block_04.png";
    return IDs;
}

To this:

function BlockID() {
    var IDs = new Object();
        IDs['s'] = "Images/Block_01.png";
        IDs['g'] = "Images/Block_02.png";
        IDs['C'] = "Images/Block_03.png";
        IDs['d'] = "Images/Block_04.png";
    return IDs;
}

There are a couple fixes to point out. First, images is not defined in your original function, so assigning property values to it will throw an error. We correct that by changing images to IDs. Second, you want to return an Object, not an Array. An object can be assigned property values akin to an associative array or hash -- an array cannot. So we change the declaration of var IDs = new Array(); to var IDs = new Object();.

After those changes your code will run fine, but it can be simplified further. You can use shorthand notation (i.e., object literal property value shorthand) to create the object and return it immediately:

function BlockID() {
    return {
            "s":"Images/Block_01.png"
            ,"g":"Images/Block_02.png"
            ,"C":"Images/Block_03.png"
            ,"d":"Images/Block_04.png"
    };
}

For SQL 2005 and up

SELECT ROW_NUMBER() OVER( ORDER BY SomeColumn ) AS 'rownumber',*
    FROM YourTable

for 2000 you need to do something like this

SELECT IDENTITY(INT, 1,1) AS Rank ,VALUE
INTO #Ranks FROM YourTable WHERE 1=0

INSERT INTO #Ranks
SELECT SomeColumn  FROM YourTable
ORDER BY SomeColumn 

SELECT * FROM #Ranks
Order By Ranks

see also here Row Number

A table alias cannot start with a @. So, give @Temp another alias (or leave out the two-part naming altogether):

SELECT *
FROM @TEMP t
WHERE t.ID = 1;

Also, a single equals sign is traditionally used in SQL for a comparison.

I'd like to add this because I spent some time solving the issue and did not find an answer here for combination of variables usage in cron and virtualenv. So maybe it'll help someone.

Thanks @davidwinterbottom, @reed-sandberg and @mkb for giving the right direction. The accepted answer actually works fine until your python need to run a script which have to run another python binary from venv/bin directory.

The problem is from regional Options . The decimal separator in win 7 for european countries is coma . You have to open Control Panel -> Regional and Language Options -> Aditional Settings -> Decimal Separator : click to enter a dot (.) and to List Separator enter a coma (,) . This is !

the only way i can think of is to find the button with javascript after it gets rendered and assign a style to it

What you are trying to do is get NTLM to forward the identity on to the next server, which it cannot do - it can only do impersonation which only gives you access to local resources. It won't let you cross a machine boundary. Kerberos authentication supports delegation (what you need) by using tickets, and the ticket can be forwarded on when all servers and applications in the chain are correctly configured and Kerberos is set up correctly on the domain. So, in short you need to switch from using NTLM to Kerberos.

.toLowerCase function only exists on strings. You can call toString() on anything in javascript to get a string representation. Putting this all together:

var ans = 334;
var temp = ans.toString().toLowerCase();
alert(temp);

I also have just faced with this problem that how to open existing file. And none of answers was helpful. That's why I tried by myself.

Direction: File -> Open file -> Workspace (with you had chosen first in creating your project) -> Package (which you already created your project in) -> src (source file) -> Created package ->

And now your searching project's nodepad format. I hope it would be helpful. If any mistake here, sorry beforehand.

Use a regex like ^\d

There is a gmail API now, which lets you send email, read email and create drafts via REST. Unlike the SMTP calls, it is non-blocking which can be a good thing for thread-based webservers sending email in the request thread (like python webservers). The API is also quite powerful.

• Of course, email should be handed off to a non-webserver queue, but it's nice to have options.

It's easiest to setup if you have Google Apps administrator rights on the domain, because then you can give blanket permission to your client. Otherwise you have to fiddle with OAuth authentication and permission.

Here is a gist demonstrating it:

See the above definition where it states that a callback function is passed off to some other function and at some point it is called.

In C++ it is desirable to have callback functions call a classes method. When you do this you have access to the member data. If you use the C way of defining a callback you will have to point it to a static member function. This is not very desirable.

Here is how you can use callbacks in C++. Assume 4 files. A pair of .CPP/.H files for each class. Class C1 is the class with a method we want to callback. C2 calls back to C1's method. In this example the callback function takes 1 parameter which I added for the readers sake. The example doesn't show any objects being instantiated and used. One use case for this implementation is when you have one class that reads and stores data into temporary space and another that post processes the data. With a callback function, for every row of data read the callback can then process it. This technique cuts outs the overhead of the temporary space required. It is particularly useful for SQL queries that return a large amount of data which then has to be post-processed.

/////////////////////////////////////////////////////////////////////
// C1 H file

class C1
{
    public:
    C1() {};
    ~C1() {};
    void CALLBACK F1(int i);
};

/////////////////////////////////////////////////////////////////////
// C1 CPP file

void CALLBACK C1::F1(int i)
{
// Do stuff with C1, its methods and data, and even do stuff with the passed in parameter
}

/////////////////////////////////////////////////////////////////////
// C2 H File

class C1; // Forward declaration

class C2
{
    typedef void (CALLBACK C1::* pfnCallBack)(int i);
public:
    C2() {};
    ~C2() {};

    void Fn(C1 * pThat,pfnCallBack pFn);
};

/////////////////////////////////////////////////////////////////////
// C2 CPP File

void C2::Fn(C1 * pThat,pfnCallBack pFn)
{
    // Call a non-static method in C1
    int i = 1;
    (pThat->*pFn)(i);
}

I've had the same exact problem in that I installed Anaconda because a python script I want to use relies on pandas, and that after so doing, python still returned the same comment that "pandas module is missing" or something to that effect.

When I typed "python" to see which python was being called, I found it was still accessing the older version of python 2.7, even though when I installed Anaconda the installer asked (and I agreed) that it would make its python the default python on my machine (PC running Windows 7).

I tried to find if there is a CONFIG.SYS file on the PC, but gave up after searching in various places (If anyone knows, please tell me). I got around the problem by writing a one-line batch script named python2.bat that called the Anaconda2 version of python, which then worked. However, it would clearly be better to change the CONFIG.SYS or whatever the PC uses to decide which version of python to call.

To add the latest solution for 2021...

I found that the project nanoid provides unique string ids that can be used as key while also being fast and very small.

After installing using npm install nanoid, use as follows:

import { nanoid } from 'nanoid';

// Have the id associated with the data.
const todos = [{id: nanoid(), text: 'first todo'}];

// Then later, it can be rendered using a stable id as the key.
const todoItems = todos.map((todo) =>
  <li key={todo.id}>
    {todo.text}
  </li>
)

You have to first clear the table and then add new data using row.add() function. At last step adjust also column size so that table renders correctly.

$('#upload-new-data').on('click', function () {
   datatable.clear().draw();
   datatable.rows.add(NewlyCreatedData); // Add new data
   datatable.columns.adjust().draw(); // Redraw the DataTable
});

Also if you want to find a mapping between old and new datatable API functions bookmark this

Have a look at the following

@using (Html.BeginForm("FileUpload", "Home", FormMethod.Post, 
                            new { enctype = "multipart/form-data" }))
{  
    <label for="file">Upload Image:</label> 
    <input type="file" name="file" id="file" style="width: 100%;" /> 
    <input type="submit" value="Upload" class="submit" /> 
}

your controller should have action method which would accept HttpPostedFileBase;

 public ActionResult FileUpload(HttpPostedFileBase file)
    {
        if (file != null)
        {
            string pic = System.IO.Path.GetFileName(file.FileName);
            string path = System.IO.Path.Combine(
                                   Server.MapPath("~/images/profile"), pic); 
            // file is uploaded
            file.SaveAs(path);

            // save the image path path to the database or you can send image 
            // directly to database
            // in-case if you want to store byte[] ie. for DB
            using (MemoryStream ms = new MemoryStream()) 
            {
                 file.InputStream.CopyTo(ms);
                 byte[] array = ms.GetBuffer();
            }

        }
        // after successfully uploading redirect the user
        return RedirectToAction("actionname", "controller name");
    }

Update 1

In case you want to upload files using jQuery with asynchornously, then try this article.

the code to handle the server side (for multiple upload) is;

 try
    {
        HttpFileCollection hfc = HttpContext.Current.Request.Files;
        string path = "/content/files/contact/";

        for (int i = 0; i < hfc.Count; i++)
        {
            HttpPostedFile hpf = hfc[i];
            if (hpf.ContentLength > 0)
            {
                string fileName = "";
                if (Request.Browser.Browser == "IE")
                {
                    fileName = Path.GetFileName(hpf.FileName);
                }
                else
                {
                    fileName = hpf.FileName;
                }
                string fullPathWithFileName = path + fileName;
                hpf.SaveAs(Server.MapPath(fullPathWithFileName));
            }
        }

    }
    catch (Exception ex)
    {
        throw ex;
    }

this control also return image name (in a javascript call back) which then you can use it to display image in the DOM.

UPDATE 2

Alternatively, you can try Async File Uploads in MVC 4.

I was trying to work with that solutions but it doesn't work. But later I was realize that the function it wasn't declared so I watch in to the dropzone.com page and take the example to call events. So finally work on my site. For those like me who don't understand JavaScript very well, I leave you the example.

<script type="text/javascript" src="/js/dropzone.js"></script>
<script type="text/javascript">
// This example uses jQuery so it creates the Dropzone, only when the DOM has
// loaded.

// Disabling autoDiscover, otherwise Dropzone will try to attach twice.
Dropzone.autoDiscover = false;
// or disable for specific dropzone:
// Dropzone.options.myDropzone = false;

$(function() {
  // Now that the DOM is fully loaded, create the dropzone, and setup the
  // event listeners
  var myDropzone = new Dropzone(".dropzone");

  myDropzone.on("queuecomplete", function(file, res) {
      if (myDropzone.files[0].status != Dropzone.SUCCESS ) {
          alert('yea baby');
      } else {
          alert('cry baby');

      }
  });
});
</script>

You can use a ScheduledExecutorService for this. First you would submit it only once to begin immediately and retain the future that is created. After that you can submit a new task that would cancel the retained future after some period of time.

 ScheduledExecutorService executor = Executors.newScheduledThreadPool(2); 
 final Future handler = executor.submit(new Callable(){ ... });
 executor.schedule(new Runnable(){
     public void run(){
         handler.cancel();
     }      
 }, 10000, TimeUnit.MILLISECONDS);

This will execute your handler (main functionality to be interrupted) for 10 seconds, then will cancel (i.e. interrupt) that specific task.

or just use for date strings 2015-05-20 or 2015.05.20

date.split(/\.|-/);

Use the below function.

function utf8_converter($array)
{
    array_walk_recursive($array, function (&$item, $key) {
        if (!mb_detect_encoding($item, 'utf-8', true)) {
                $item = utf8_encode($item);
        }
    });

    return $array;
}

These are my rules of thumb:

If default values can be calculated from other parameters, use default expressions as in:

fun <- function(x,levels=levels(x)){
    blah blah blah
}

if otherwise using missing

fun <- function(x,levels){
    if(missing(levels)){
        [calculate levels here]
    }
    blah blah blah
}

In the rare case that you thing a user may want to specify a default value that lasts an entire R session, use getOption

fun <- function(x,y=getOption('fun.y','initialDefault')){# or getOption('pkg.fun.y',defaultValue)
    blah blah blah
}

If some parameters apply depending on the class of the first argument, use an S3 generic:

fun <- function(...)
    UseMethod(...)


fun.character <- function(x,y,z){# y and z only apply when x is character
   blah blah blah 
}

fun.numeric <- function(x,a,b){# a and b only apply when x is numeric
   blah blah blah 
}

fun.default <- function(x,m,n){# otherwise arguments m and n apply
   blah blah blah 
}

Use ... only when you are passing additional parameters on to another function

cat0 <- function(...)
    cat(...,sep = '')

Finally, if you do choose the use ... without passing the dots onto another function, warn the user that your function is ignoring any unused parameters since it can be very confusing otherwise:

fun <- (x,...){
    params <- list(...)
    optionalParamNames <- letters
    unusedParams <- setdiff(names(params),optionalParamNames)
    if(length(unusedParams))
        stop('unused parameters',paste(unusedParams,collapse = ', '))
   blah blah blah 
}

private void textbox1_KeyDown_1(object sender, KeyEventArgs e)
{
    if (e.Key >= Key.A && e.Key <= Key.Z)
    {
    }
    else
    {
       e.Handled = true;
    }
}

int position = 0;
listview.setItemChecked(position, true);
View wantedView = adapter.getView(position, null, listview);

From RFC 6750, Section 1.2:

Bearer Token

A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).

The Bearer Token or Refresh token is created for you by the Authentication server. When a user authenticates your application (client) the authentication server then goes and generates for your a Bearer Token (refresh token) which you can then use to get an access token.

The Bearer Token is normally some kind of cryptic value created by the authentication server, it isn't random it is created based upon the user giving you access and the client your application getting access.

You can reverse the rows in an even simpler way:

df[::-1]

Instead of worrying about every single apostrophe in your statement. You can easily use the q' Notation.

Example

SELECT q'(Alex's Tea Factory)' FROM DUAL;

Key Components in this notation are

• q' which denotes the starting of the notation
• ( an optional symbol denoting the starting of the statement to be fully escaped.
• Alex's Tea Factory (Which is the statement itself)
• )' A closing parenthesis with a apostrophe denoting the end of the notation.

And such that, you can stuff how many apostrophes in the notation without worrying about each single one of them, they're all going to be handled safely.

IMPORTANT NOTE

Since you used ( you must close it with )', and remember it's optional to use any other symbol, for instance, the following code will run exactly as the previous one

SELECT q'[Alex's Tea Factory]' FROM DUAL;

In Swift 4:

let dict = ["Item1":2.4, "Item2": 5.4, "Item3" : 6.5]

let array = Array(dict.values)

Here is what worked here: Simulates Excel 2003 (Save as CSV format)

SELECT 
REPLACE( IFNULL(notes, ''), '\r\n' , '\n' )   AS notes
FROM sometables
INTO OUTFILE '/tmp/test.csv' 
FIELDS TERMINATED BY ',' ENCLOSED BY '"' ESCAPED BY '"'
LINES TERMINATED BY '\r\n';

1. Excel saves \r\n for line separators.
2. Excel saves \n for newline characters within column data
3. Have to replace \r\n inside your data first otherwise Excel will think its a start of the next line.

Modern Javascript implementations with the template syntax using backticks are also an easy way to assign an HTML block of code to a variable:

    const firstName = 'Sam';
    const fullName = 'Sam Smith';
    const htmlString = `<h1>Hello ${fullName}!</h1><p>This is some content \
        that will display. You can even inject your first name, ${firstName}, \
        in the code.</p><p><a href="http://www.google.com">Search</a> for \
        stuff on the Google website.</p>`;

I faced this issue with tomcat 7 + jdk 1.8

with java 1.7 and lower versions it's working fine.

window -> preferences -> java -> installed jre

in my case I changed jre1.8 to JDK 1.7

and accordingly modify project facet , select same java version as it's there in selected Installed JRE.

If you're strictly defining the function yourself and it's a relatively short definition, a solution without dependencies would be to define the function in a string and assign the eval() of the expression to your function.

E.g.

funcstring = 'lambda x: x> 5'
func = eval(funcstring)

then optionally to attach the original code to the function:

func.source = funcstring

I dont think adding dual functions inside the toggle function works for a registered click event (Unless I'm missing something)

For example:

$('.btnName').click(function() {
 top.$('#panel').toggle(function() {
   $(this).animate({ 
     // style change
   }, 500);
   },
   function() {
   $(this).animate({ 
     // style change back
   }, 500);
 });

In line with the other answers, there are multiple ways to call super class methods (including the constructor), however in Python-3.x the process has been simplified:

Python-2.x

class A(object):
 def __init__(self):
   print "world"

class B(A):
 def __init__(self):
   print "hello"
   super(B, self).__init__()

Python-3.x

class A(object):
 def __init__(self):
   print("world")

class B(A):
 def __init__(self):
   print("hello")
   super().__init__()

super() is now equivalent to super(<containing classname>, self) as per the docs.

Here's some info if someone comes upon this in 2019.

I think reduce vs map + filter might be somewhat dependent on what you need to loop through. Not sure on this but reduce does seem to be slower.

One thing is for sure - if you're looking for performance improvements the way you write the code is extremely important!

Here a JS perf test that shows the massive improvements when typing out the code fully rather than checking for "falsey" values (e.g. if (string) {...}) or returning "falsey" values where a boolean is expected.

Hope this helps someone
