If it is not defined in the web service or application or server (apache or IIS) that is hosting the web service consumable then you could create infinite connections until failure

Change the node to and create a file, packages.xsd, in the same folder (and include it in the project) with the following contents:

It is possible using ConfigTransform build target available as a Nuget package - https://www.nuget.org/packages/CodeAssassin.ConfigTransform/

All "web.*.config" transform files will be transformed and output as a series of "web.*.config.transformed" files in the build output directory regardless of the chosen build configuration.

The same applies to "app.*.config" transform files in non-web projects.

and then adding the following target to your *.csproj.

<Target Name="TransformActiveConfiguration" Condition="Exists('$(ProjectDir)/Web.$(Configuration).config')" BeforeTargets="Compile" >
    <TransformXml Source="$(ProjectDir)/Web.Config" Transform="$(ProjectDir)/Web.$(Configuration).config" Destination="$(TargetDir)/Web.config" />
</Target>

Posting an answer as this is the first Stackoverflow post that appears in Google on the subject.

Using sn.exe utility:

sn -T YourAssembly.dll

or loading the assembly in Reflector.

If you want to add the string value to a button for example, simple use

android:text="@string/NameOfTheString"

The defined text in strings.xml looks like this:

 <string name="NameOfTheString">Test string</string>

The problem will be that you cannot represent 0.575 exactly as a binary floating point number (eg a double). Though I don't know exactly it seems that the representation closest is probably just a bit lower and so when rounding it uses the true representation and rounds down.

If you want to avoid this problem then use a more appropriate data type. decimal will do what you want:

Math.Round(0.575M, 2, MidpointRounding.AwayFromZero)

Result: 0.58

The reason that 0.75 does the right thing is that it is easy to represent in binary floating point since it is simple 1/2 + 1/4 (ie 2^-1 +2^-2). In general any finite sum of powers of two can be represented in binary floating point. Exceptions are when your powers of 2 span too great a range (eg 2^100+2 is not exactly representable).

Edit to add:

Formatting doubles for output in C# might be of interest in terms of understanding why its so hard to understand that 0.575 is not really 0.575. The DoubleConverter in the accepted answer will show that 0.575 as an Exact String is 0.5749999999999999555910790149937383830547332763671875 You can see from this why rounding give 0.57.

If you just want to get the first decimal value, the solution is really simple.

Here's an explanatory example:

int leftSideOfDecimalPoint = (int) initialFloatValue; // The cast from float to int keeps only the integer part

int temp = (int) initialFloatValue * 10;
int rightSideOfDecimalPoint = temp % 10;

Say for example we have an initial float value of 27.8 .

• By just casting the initial float value to an int, you discard the fraction part and only keep the integer part.
• By multiplying the initial float value by 10 we get a result of 278.0, then by casting this result to int, gives you the value of 278
• If we divide 278 by 10, we get 27.8, of which the remainder is 8, which is the value at the right side of the decimal point. Thus use modulus.

This technique can then be used to get the following decimal characters by using for example 100 instead of 10, and so on.

Just take note that if you use this technique on real-time systems, for example to display it on a 7-segment display, it may not work properly because we are multiplying with a float value, where multiplication takes a lot of overhead time.

If you for example want the icon of glyphicon-chevron-left

Try adding class="glyphicon glyphicon-chevron-left"

Ok so if I understand well you're trying to get a random string password which contains 5 letters and 3 numbers randomly positioned and so which has a length of 8 characters and you accept maj and min letters, you can do that with the following function:

function randPass(lettersLength,numbersLength) {
    var j, x, i;
    var result           = '';
    var letters       = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';
    var numbers       = '0123456789';
    for (i = 0; i < lettersLength; i++ ) {
        result += letters.charAt(Math.floor(Math.random() * letters.length));
    }
    for (i = 0; i < numbersLength; i++ ) {
        result += numbers.charAt(Math.floor(Math.random() * numbers.length));
    }
    result = result.split("");
    for (i = result.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i + 1));
        x = result[i];
        result[i] = result[j];
        result[j] = x;
    }
    result = result.join("");
    return result
}

function randPass(lettersLength,numbersLength) {_x000D_
    var j, x, i;_x000D_
    var result           = '';_x000D_
    var letters       = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';_x000D_
    var numbers       = '0123456789';_x000D_
    for (i = 0; i < lettersLength; i++ ) {_x000D_
        result += letters.charAt(Math.floor(Math.random() * letters.length));_x000D_
    }_x000D_
    for (i = 0; i < numbersLength; i++ ) {_x000D_
        result += numbers.charAt(Math.floor(Math.random() * numbers.length));_x000D_
    }_x000D_
    result = result.split("");_x000D_
    for (i = result.length - 1; i > 0; i--) {_x000D_
        j = Math.floor(Math.random() * (i + 1));_x000D_
        x = result[i];_x000D_
        result[i] = result[j];_x000D_
        result[j] = x;_x000D_
    }_x000D_
    result = result.join("");_x000D_
    return result_x000D_
}_x000D_
console.log(randPass(5,3))

I use if (ptr), but this is completely not worth arguing about.

I like my way because it's concise, though others say == NULL makes it easier to read and more explicit. I see where they're coming from, I just disagree the extra stuff makes it any easier. (I hate the macro, so I'm biased.) Up to you.

I disagree with your argument. If you're not getting warnings for assignments in a conditional, you need to turn your warning levels up. Simple as that. (And for the love of all that is good, don't switch them around.)

Note in C++0x, we can do if (ptr == nullptr), which to me does read nicer. (Again, I hate the macro. But nullptr is nice.) I still do if (ptr), though, just because it's what I'm used to.

My solution in code behind was:

System.Web.UI.WebControls.FileUpload fileUpload;

I don't know why, but when you are using FileUpload without System.Web.UI.WebControls it is referencing to YourProject.FileUpload not System.Web.UI.WebControls.FileUpload.

You can also get this error by prematurely taking PyCharm's advice to annotate a method @staticmethod. Remove the annotation.

svn merge -r 1944:1943 . should revert the changes of r1944 in your working copy. You can then review the changes in your working copy (with diff), but you'd need to commit in order to apply the revert into the repository.

If you are not using Math.round() function the solution suggested by Dr.Molle will not work in some cases when a browser window has a zoom.

For example $(this).scrollTop() + $(this).innerHeight() = 600

$(this)[0].scrollHeight yields = 599.99998

600 >= 599.99998 fails.

Here is the correct code:

jQuery(function($) {
    $('#flux').on('scroll', function() {
        if(Math.round($(this).scrollTop() + $(this).innerHeight(), 10) >= Math.round($(this)[0].scrollHeight, 10)) {
            alert('end reached');
        }
    })
});

You may also add some extra margin pixels if you do not need a strict condition

var margin = 4

jQuery(function($) {
    $('#flux').on('scroll', function() {
        if(Math.round($(this).scrollTop() + $(this).innerHeight(), 10) >= Math.round($(this)[0].scrollHeight, 10) - margin) {
            alert('end reached');
        }
    })
});

 public static boolean deleteDirectory(File path) {
    // TODO Auto-generated method stub
    if( path.exists() ) {
        File[] files = path.listFiles();
        for(int i=0; i<files.length; i++) {
            if(files[i].isDirectory()) {
                deleteDirectory(files[i]);
            }
            else {
                files[i].delete();
            }
        }
    }
    return(path.delete());
 }

This Code will Help you.. And In Android Manifest You have to get Permission to make modification..

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Consider such a solution without a need to define the third variable:

function swap(arr, from, to) {_x000D_
  arr.splice(from, 1, arr.splice(to, 1, arr[from])[0]);_x000D_
}_x000D_
_x000D_
var letters = ["a", "b", "c", "d", "e", "f"];_x000D_
_x000D_
swap(letters, 1, 4);_x000D_
_x000D_
console.log(letters); // ["a", "e", "c", "d", "b", "f"]

Note: You may want to add additional checks for example for array length. This solution is mutable so swap function does not need to return a new array, it just does mutation over array passed into.

Why not just extend the Android CheckBox to have better padding instead. That way instead of having to fix it in code every time you use the CheckBox you can just use the fixed CheckBox instead.

First Extend CheckBox:

package com.whatever;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.CheckBox;

/**
 * This extends the Android CheckBox to add some more padding so the text is not on top of the
 * CheckBox.
 */
public class CheckBoxWithPaddingFix extends CheckBox {

    public CheckBoxWithPaddingFix(Context context) {
        super(context);
    }

    public CheckBoxWithPaddingFix(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public CheckBoxWithPaddingFix(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public int getCompoundPaddingLeft() {
        final float scale = this.getResources().getDisplayMetrics().density;
        return (super.getCompoundPaddingLeft() + (int) (10.0f * scale + 0.5f));
    }
}

Second in your xml instead of creating a normal CheckBox create your extended one

<com.whatever.CheckBoxWithPaddingFix
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello there" />

Variables can contain single quotes.

myvar=\'....$variable\'

repo forall -c $myvar

I was having the same problem, and solved it by replacing Manifest.permission.READ_PHONE_STATE with android.Manifest.permission.READ_PHONE_STATE.

We can also do this using randint.

from random import randint
l= ['a','b','c']

def get_rand_element(l):
    if l:
        return l[randint(0,len(l)-1)]
    else:
        return None

get_rand_element(l)

Something like this should work:

sh -c 'cd /tmp && exec pwd'

Value of %TEMP% environment variable is often user-specific and Windows sets it up with regard to currently logged in user account. Some user accounts may have no user profile, for example when your process runs as a service on SYSTEM, LOCALSYSTEM or other built-in account, or is invoked by IIS application with AppPool identity with Create user profile option disabled. So even when you do not overwrite %TEMP% variable explicitly, Windows may use c:\temp or even c:\windows\temp folders for, lets say, non-usual user accounts. And what's more important, process might have no access rights to this directory!

Same problem with Chrome : I had in my html page the following code :

<body>
  ...
  <script src="http://myserver/lib/load.js"></script>
  ...
</body>

But the load.js was always in status pending when looking in the Network pannel.

I found a workaround using asynchronous load of load.js:

<body>
  ...
  <script>
    setTimeout(function(){
      var head, script;
      head = document.getElementsByTagName("head")[0];
      script = document.createElement("script");
      script.src = "http://myserver/lib/load.js";
      head.appendChild(script);
    }, 1);
  </script>
  ...
</body>

Now its working fine.

The simplest solution what works for me is to store the data as json_encode.

later when you retrieve just make sure you json_decode it.

Here you don't have to change the collation or the character set of the database and the table.

You can delete the browser cache by setting these headers:

<?php
header("Expires: Tue, 01 Jan 2000 00:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
?>

Try to execute below command in your terminal :

mysql -h localhost -P 3306 -u root -p

If you successfully connect to your database, then same thing has to happen with Mysql Workbench.

If you are unable to connect then I think 3306 port is acquired by another process.

Find which process running on 3306 port. If required, give admin privileges using sudo.

netstat -lnp | grep 3306

Kill/stop that process and restart your MySQL server. You are good to go.

Execute below command to find my.cnf file in macbook.

mysql --help | grep cnf

You can change MySQL port to any available port in your system. But after that, make sure you restart MySQL server.

This was my scenario:

for i in generate_numbers():
    do_something(i)
# Use the last i.

I can’t easily determine the length of the iterable, and that means that i may or may not exist depending on whether the iterable produces an empty sequence.

If I want to use the last i of the iterable (an i that doesn’t exist for an empty sequence) I can do one of two things:

i = None  # Declare the variable.
for i in generate_numbers():
    do_something(i)
use_last(i)

or

for i in generate_numbers():
    do_something(i)
try:
    use_last(i)
except UnboundLocalError:
    pass  # i didn’t exist because sequence was empty.

The first solution may be problematic because I can’t tell (depending on the sequence values) whether i was the last element. The second solution is more accurate in that respect.

You can choose:

if [[ $? -ne 0 ]]; then       # -ne: not equal

if ! [[ $? -eq 0 ]]; then     # -eq: equal

if [[ ! $? -eq 0 ]]; then

! inverts the return of the following expression, respectively.

Here is how you can do it :

public static void main(String[] args) {
    // TODO Auto-generated method stub
    int x = 3;
    int y = 2;
    Float fX = new Float(x);
    float res = fX.floatValue()/y;
    System.out.println("res = "+res);
}

See you !

Just use z-index CSS property as described in the highest liked answer and the nav bar will stick to the top.

Example:

<div class="navigation">
 <nav>
   <ul>
    <li>Home</li>
    <li>Contact</li>
   </ul>
 </nav>

.navigation {
   /* fixed keyword is fine too */
   position: sticky;
   top: 0;
   z-index: 100;
   /* z-index works pretty much like a layer:
   the higher the z-index value, the greater
   it will allow the navigation tag to stay on top
   of other tags */
}

I think that the fastest way to do this is to just clone the node, which will remove all event listeners:

var old_element = document.getElementById("btn");
var new_element = old_element.cloneNode(true);
old_element.parentNode.replaceChild(new_element, old_element);

Just be careful, as this will also clear event listeners on all child elements of the node in question, so if you want to preserve that you'll have to resort to explicitly removing listeners one at a time.

math.e or from math import e (= 2.718281…)

The two expressions math.exp(x) and e**x are equivalent however:
Return e raised to the power x, where e = 2.718281… is the base of natural logarithms. This is usually more accurate than math.e ** x or pow(math.e, x). docs.python

for power use ** (3**2 = 9), not " ^ "
" ^ " is a bitwise XOR operator (& and, | or), it works logicaly with bits. So for example 10^4=14 (maybe unexpectedly) ? consider the bitwise depiction:

(0000 1010 ^ 0000 0100 = 0000 1110) programiz

The "evil" answer did not work for me. Instead, I used what was recommended on the JSHints docs page. If you know the warning that is thrown, you can turn it off for a block of code. For example, I am using some third party code that does not use camel case functions, yet my JSHint rules require it, which led to a warning. To silence it, I wrote:

/*jshint -W106 */
save_state(id);
/*jshint +W106 */

<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

Above two answers are correct but didn't work for me.

1. I kept on seeing blank like below for docker container ls
2. then I tried, docker container ls -a and after that it showed all the process previously exited and running.
3. Then docker stop <container id> or docker container stop <container id> didn't work
4. then I tried docker rm -f <container id> and it worked.
5. Now at this I tried docker container ls -a and this process wasn't present.

I added 40px-height .vspace element holding the anchor before each of my h1 elements.

<div class="vspace" id="gherkin"></div>
<div class="page-header">
  <h1>Gherkin</h1>
</div>

In the CSS:

.vspace { height: 40px;}

It's working great and the space is not chocking.

Use this

openssl ciphers -v | awk '{print $2}' | sort | uniq

Here are clarified instruction combining Dawn Song's answer and Marmor's answer.

Drag a long Press Gesture Recognizer and drop it into your Table Cell. It will jump to the bottom of the list on the left.

Then connect the gesture recognizer the same way you would connect a button.

Add the code from Marmor in the the action handler

- (IBAction)handleLongPress:(UILongPressGestureRecognizer *)sender {
if (sender.state == UIGestureRecognizerStateBegan) {

    CGPoint p = [sender locationInView:self.tableView];

    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:p];
    if (indexPath == nil) {
        NSLog(@"long press on table view but not on a row");
    } else {
        UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
        if (cell.isHighlighted) {
            NSLog(@"long press on table view at section %d row %d", indexPath.section, indexPath.row);
        }
    }
}

}

I know this is a really old post, but I found it in searching for a solution to the same problem. I don't want a nested if-statement, and Switch is apparently newer than the version of Excel I'm using. I figured out what was going wrong with my code, so I figured I'd share here in case it helps someone else.

I remembered that VLOOKUP requires the source table to be sorted alphabetically/numerically for it to work. I was initially trying to do this...

=LOOKUP(LOWER(LEFT($T$3, 1)),  {"s","l","m"}, {-1,1,0})

and it started working when I did this...

=LOOKUP(LOWER(LEFT($T$3, 1)),  {"l","m","s"}, {1,0,-1})

I was initially thinking the last value might turn out to be a default, so I wanted the zero at the last place. That doesn't seem to be the behavior anyway, so I just put the possible matches in order, and it worked.

Edit: As a final note, I see that the example in the original post has letters in alphabetical order, but I imagine the real use case might have been different if the error was happening and the letters A, B, and C were just examples.

If using Angular >= 1.4, here's the cleanest solution I've found that doesn't rely on anything custom or external:

angular.module('yourModule')
  .config(function ($httpProvider, $httpParamSerializerJQLikeProvider){
    $httpProvider.defaults.transformRequest.unshift($httpParamSerializerJQLikeProvider.$get());
    $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded; charset=utf-8';
});

And then you can do this anywhere in your app:

$http({
  method: 'POST',
  url: '/requesturl',
  data: {
    param1: 'value1',
    param2: 'value2'
  }
});

And it will correctly serialize the data as param1=value1&param2=value2 and send it to /requesturl with the application/x-www-form-urlencoded; charset=utf-8 Content-Type header as it's normally expected with POST requests on endpoints.

Rendering happens after change detection. To force change detection, so that component property values that have changed get propagated to the DOM (and then the browser will render those changes in the view), here are some options:

• ApplicationRef.tick() - similar to Angular 1's $rootScope.$digest() -- i.e., check the full component tree
• NgZone.run(callback) - similar to $rootScope.$apply(callback) -- i.e., evaluate the callback function inside the Angular 2 zone. I think, but I'm not sure, that this ends up checking the full component tree after executing the callback function.
• ChangeDetectorRef.detectChanges() - similar to $scope.$digest() -- i.e., check only this component and its children

You will need to import and then inject ApplicationRef, NgZone, or ChangeDetectorRef into your component.

For your particular scenario, I would recommend the last option if only a single component has changed.

*Please try the below codes

"250000".replace(/(\d)(?=(\d{3})+(?!\d))/g, '$1,');

Ans: 250,000

A better way to normalize your image is to take each value and divide by the largest value experienced by the data type. This ensures that images that have a small dynamic range in your image remain small and they're not inadvertently normalized so that they become gray. For example, if your image had a dynamic range of [0-2], the code right now would scale that to have intensities of [0, 128, 255]. You want these to remain small after converting to np.uint8.

Therefore, divide every value by the largest value possible by the image type, not the actual image itself. You would then scale this by 255 to produced the normalized result. Use numpy.iinfo and provide it the type (dtype) of the image and you will obtain a structure of information for that type. You would then access the max field from this structure to determine the maximum value.

So with the above, do the following modifications to your code:

import numpy as np
import cv2
[...]
info = np.iinfo(data.dtype) # Get the information of the incoming image type
data = data.astype(np.float64) / info.max # normalize the data to 0 - 1
data = 255 * data # Now scale by 255
img = data.astype(np.uint8)
cv2.imshow("Window", img)

Note that I've additionally converted the image into np.float64 in case the incoming data type is not so and to maintain floating-point precision when doing the division.

Or you can simply use OleDbDataAdapter to get data from Excel

You can see all of your activities (recently uploaded builds here). It will also provide current status of your build.

You can include a .js file which has the script to set the

window.location.href = url;

Where url would be the url you wish to load.

You can change the tint, quite easily in code via:

imageView.setColorFilter(Color.argb(255, 255, 255, 255)); // White Tint

If you want color tint then

imageView.setColorFilter(ContextCompat.getColor(context, R.color.COLOR_YOUR_COLOR), android.graphics.PorterDuff.Mode.MULTIPLY);

For Vector Drawable

imageView.setColorFilter(ContextCompat.getColor(context, R.color.COLOR_YOUR_COLOR), android.graphics.PorterDuff.Mode.SRC_IN);

UPDATE:
@ADev has newer solution in his answer here, but his solution requires newer support library - 25.4.0 or above.

I'd like to clarify a few things:

1. As other answers have pointed out, the simplest thing to do is use pandas.Series.tolist(). I'm not sure why the top voted answer leads off with using pandas.Series.values.tolist() since as far as I can tell, it adds syntax/confusion with no added benefit.
2. tst[lookupValue][['SomeCol']] is a dataframe (as stated in the question), not a series (as stated in a comment to the question). This is because tst[lookupValue] is a dataframe, and slicing it with [['SomeCol']] asks for a list of columns (that list that happens to have a length of 1), resulting in a dataframe being returned. If you remove the extra set of brackets, as in tst[lookupValue]['SomeCol'], then you are asking for just that one column rather than a list of columns, and thus you get a series back.
3. You need a series to use pandas.Series.tolist(), so you should definitely skip the second set of brackets in this case. FYI, if you ever end up with a one-column dataframe that isn't easily avoidable like this, you can use pandas.DataFrame.squeeze() to convert it to a series.
4. tst[lookupValue]['SomeCol'] is getting a subset of a particular column via chained slicing. It slices once to get a dataframe with only certain rows left, and then it slices again to get a certain column. You can get away with it here since you are just reading, not writing, but the proper way to do it is tst.loc[lookupValue, 'SomeCol'] (which returns a series).
5. Using the syntax from #4, you could reasonably do everything in one line: ID = tst.loc[tst['SomeCol'] == 'SomeValue', 'SomeCol'].tolist()

Demo Code:

import pandas as pd
df = pd.DataFrame({'colA':[1,2,1],
                   'colB':[4,5,6]})
filter_value = 1

print "df"
print df
print type(df)

rows_to_keep = df['colA'] == filter_value
print "\ndf['colA'] == filter_value"
print rows_to_keep
print type(rows_to_keep)

result = df[rows_to_keep]['colB']
print "\ndf[rows_to_keep]['colB']"
print result
print type(result)

result = df[rows_to_keep][['colB']]
print "\ndf[rows_to_keep][['colB']]"
print result
print type(result)

result = df[rows_to_keep][['colB']].squeeze()
print "\ndf[rows_to_keep][['colB']].squeeze()"
print result
print type(result)

result = df.loc[rows_to_keep, 'colB']
print "\ndf.loc[rows_to_keep, 'colB']"
print result
print type(result)

result = df.loc[df['colA'] == filter_value, 'colB']
print "\ndf.loc[df['colA'] == filter_value, 'colB']"
print result
print type(result)

ID = df.loc[rows_to_keep, 'colB'].tolist()
print "\ndf.loc[rows_to_keep, 'colB'].tolist()"
print ID
print type(ID)

ID = df.loc[df['colA'] == filter_value, 'colB'].tolist()
print "\ndf.loc[df['colA'] == filter_value, 'colB'].tolist()"
print ID
print type(ID)

Result:

df
   colA  colB
0     1     4
1     2     5
2     1     6

<class 'pandas.core.series.Series'>

df.loc[rows_to_keep, 'colB'].tolist()
[4, 6]
<type 'list'>

df.loc[df['colA'] == filter_value, 'colB'].tolist()
[4, 6]
<type 'list'>

Although the question is: How do I get control early enough to issue an error message and exit?

The question that I answer is: How do I get control early enough to issue an error message before starting the app?

I can answer it a lot differently then the other posts. Seems answers so far are trying to solve your question from within Python.

I say, do version checking before launching Python. I see your path is Linux or unix. However I can only offer you a Windows script. I image adapting it to linux scripting syntax wouldn't be too hard.

Here is the DOS script with version 2.7:

@ECHO OFF
REM see http://ss64.com/nt/for_f.html
FOR /F "tokens=1,2" %%G IN ('"python.exe -V 2>&1"') DO ECHO %%H | find "2.7" > Nul
IF NOT ErrorLevel 1 GOTO Python27
ECHO must use python2.7 or greater
GOTO EOF
:Python27
python.exe tern.py
GOTO EOF
:EOF

This does not run any part of your application and therefore will not raise a Python Exception. It does not create any temp file or add any OS environment variables. And it doesn't end your app to an exception due to different version syntax rules. That's three less possible security points of access.

The FOR /F line is the key.

FOR /F "tokens=1,2" %%G IN ('"python.exe -V 2>&1"') DO ECHO %%H | find "2.7" > Nul

just look at cv2.randu() or cv.randn(), it's all pretty similar to matlab already, i guess.

let's play a bit ;) :

import cv2
import numpy as np

>>> im = np.empty((5,5), np.uint8) # needs preallocated input image
>>> im
array([[248, 168,  58,   2,   1],  # uninitialized memory counts as random, too ?  fun ;) 
       [  0, 100,   2,   0, 101],
       [  0,   0, 106,   2,   0],
       [131,   2,   0,  90,   3],
       [  0, 100,   1,   0,  83]], dtype=uint8)
>>> im = np.zeros((5,5), np.uint8) # seriously now.
>>> im
array([[0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0]], dtype=uint8)
>>> cv2.randn(im,(0),(99))         # normal
array([[  0,  76,   0, 129,   0],
       [  0,   0,   0, 188,  27],
       [  0, 152,   0,   0,   0],
       [  0,   0, 134,  79,   0],
       [  0, 181,  36, 128,   0]], dtype=uint8)
>>> cv2.randu(im,(0),(99))         # uniform
array([[19, 53,  2, 86, 82],
       [86, 73, 40, 64, 78],
       [34, 20, 62, 80,  7],
       [24, 92, 37, 60, 72],
       [40, 12, 27, 33, 18]], dtype=uint8)

to apply it to an existing image, just generate noise in the desired range, and add it:

img = ...
noise = ...

image = img + noise

These are properties. You would use them like so:

Tom.Title = "Accountant";
string desc = Tom.Description;

But considering they are declared protected their visibility may be a concern.

Remove these two lines:

xmlHttp.setRequestHeader("Content-length", params.length);
xmlHttp.setRequestHeader("Connection", "close");

XMLHttpRequest isn't allowed to set these headers, they are being set automatically by the browser. The reason is that by manipulating these headers you might be able to trick the server into accepting a second request through the same connection, one that wouldn't go through the usual security checks - that would be a security vulnerability in the browser.

If you need to do something on the front end you can respond to the onsubmit event of your form. If you are just posting to admin/start you can access post variables in your view through the request object. request.POST which is a dictionary of post variables

I got the answer.

Here is the code:

SELECT * FROM table
WHERE STR_TO_DATE(column, '%d/%m/%Y')
  BETWEEN STR_TO_DATE('29/01/15', '%d/%m/%Y')
    AND STR_TO_DATE('07/10/15', '%d/%m/%Y')

Basically any file that is automatically regenerated.

A good test is to clone your repo and see if Android Studio is able to interpret and run your project immediately (generating what is missing).
If not, find what is missing, and make sure it isn't ignored, but added to the repo.

That being said, you can take example on existing .gitignore files, like the Android one.

# built application files
*.apk
*.ap_

# files for the dex VM
*.dex

# Java class files
*.class

# generated files
bin/
gen/

# Local configuration file (sdk path, etc)
local.properties

# Eclipse project files
.classpath
.project

# Proguard folder generated by Eclipse
proguard/

# Intellij project files
*.iml
*.ipr
*.iws
.idea/

Use re.sub, like so:

>>> import re
>>> re.sub('\D', '', 'aas30dsa20')
'3020'

\D matches any non-digit character so, the code above, is essentially replacing every non-digit character for the empty string.

Or you can use filter, like so (in Python 2):

>>> filter(str.isdigit, 'aas30dsa20')
'3020'

Since in Python 3, filter returns an iterator instead of a list, you can use the following instead:

>>> ''.join(filter(str.isdigit, 'aas30dsa20'))
'3020'

As everyone mentioned, it might not be a good idea for layout purposes. I arrived to this question because I was wondering the same and I only wanted to know if it would be valid code.

Since it's valid, you can use it for other purposes. For example, what I'm going to use it for is to put some fancy "CSSed" divs inside table rows and then use a quick jQuery function to allow the user to sort the information by price, name, etc. This way, the only layout table will give me is the "vertical order", but I'll control width, height, background, etc of the divs by CSS.

The perfect solution which works undoubtedly is to just add these packages to your app:
https://mvnrepository.com/artifact/org.slf4j/slf4j-api/1.7.2
http://archive.apache.org/dist/logging/log4j/1.2.16/

after adding so you may encounter following WARNING which you can simply ignore!

You can use a session object. It stores the cookies so you can make requests, and it handles the cookies for you

s = requests.Session() 
# all cookies received will be stored in the session object

s.post('http://www...',data=payload)
s.get('http://www...')

Docs: https://requests.readthedocs.io/en/master/user/advanced/#session-objects

You can also save the cookie data to an external file, and then reload them to keep session persistent without having to login every time you run the script:

Go via POSIXct and you want to set a TZ there -- here you see my (Chicago) default:

R> val <- 1352068320
R> as.POSIXct(val, origin="1970-01-01")
[1] "2012-11-04 22:32:00 CST"
R> as.Date(as.POSIXct(val, origin="1970-01-01"))
[1] "2012-11-05" 
R> 

Edit: A few years later, we can now use the anytime package:

R> library(anytime)
R> anytime(1352068320)
[1] "2012-11-04 16:32:00 CST"
R> anydate(1352068320)
[1] "2012-11-04"
R> 

Note how all this works without any format or origin arguments.

If you're using Rails 3.2 or Rails 4 you should use request.original_url to get the current URL.

Documentation for the method is at http://api.rubyonrails.org/classes/ActionDispatch/Request.html#method-i-original_url but if you're curious the implementation is:

def original_url
  base_url + original_fullpath
end

type C:\temp\test.bat>C:\temp\test.log

you must clear the target file such as in jar and others In C: drive your folder at .m2 see the location where it install and delete the .jar file,Snaphot file and delete target files then clean the application you found it will be run

update: nowadays we have mobile and custom keyboards and we cannot continue trusting these arbitrary key codes such as 13 and 186. in other words, stop using event.which/event.keyCode and start using event.key:

if (event.key === "Enter" || event.key === "ArrowUp" || event.key === "ArrowDown")

Like the accepted answer well explained by lhunath, you can use

command > >(tee -a stdout.log) 2> >(tee -a stderr.log >&2)

Beware than if you use bash you could have some issue.

Let me take the matthew-wilcoxson exemple.

And for those who "seeing is believing", a quick test:

(echo "Test Out";>&2 echo "Test Err") > >(tee stdout.log) 2> >(tee stderr.log >&2)

Personally, when I try, I have this result :

user@computer:~$ (echo "Test Out";>&2 echo "Test Err") > >(tee stdout.log) 2> >(tee stderr.log >&2)
user@computer:~$ Test Out
Test Err

Both message does not appear at the same level. Why Test Out seem to be put like if it is my previous command ?
Prompt is on a blank line, let me think the process is not finished, and when I press Enter this fix it.
When I check the content of the files, it is ok, redirection works.

Let take another test.

function outerr() {
  echo "out"     # stdout
  echo >&2 "err" # stderr
}

user@computer:~$ outerr
out
err

user@computer:~$ outerr >/dev/null
err

user@computer:~$ outerr 2>/dev/null
out

Trying again the redirection, but with this function.

function test_redirect() {
  fout="stdout.log"
  ferr="stderr.log"
  echo "$ outerr"
  (outerr) > >(tee "$fout") 2> >(tee "$ferr" >&2)
  echo "# $fout content :"
  cat "$fout"
  echo "# $ferr content :"
  cat "$ferr"
}

Personally, I have this result :

user@computer:~$ test_redirect
$ outerr
# stdout.log content :
out
out
err
# stderr.log content :
err
user@computer:~$

No prompt on a blank line, but I don't see normal output, stdout.log content seem to be wrong, only stderr.log seem to be ok. If I relaunch it, output can be different...

So, why ?

Because, like explained here :

Beware that in bash, this command returns as soon as [first command] finishes, even if the tee commands are still executed (ksh and zsh do wait for the subprocesses)

So, if you use bash, prefer use the better exemple given in this other answer :

{ { outerr | tee "$fout"; } 2>&1 1>&3 | tee "$ferr"; } 3>&1 1>&2

It will fix the previous issues.

Now, the question is, how to retrieve exit status code ?
$? does not works.
I have no found better solution than switch on pipefail with set -o pipefail (set +o pipefail to switch off) and use ${PIPESTATUS[0]} like this

function outerr() {
  echo "out"
  echo >&2 "err"
  return 11
}

function test_outerr() {
  local - # To preserve set option
  ! [[ -o pipefail ]] && set -o pipefail; # Or use second part directly
  local fout="stdout.log"
  local ferr="stderr.log"
  echo "$ outerr"
  { { outerr | tee "$fout"; } 2>&1 1>&3 | tee "$ferr"; } 3>&1 1>&2
  # First save the status or it will be lost
  local status="${PIPESTATUS[0]}" # Save first, the second is 0, perhaps tee status code.
  echo "==="
  echo "# $fout content :"
  echo "<==="
  cat "$fout"
  echo "===>"
  echo "# $ferr content :"
  echo "<==="
  cat "$ferr"
  echo "===>"
  if (( status > 0 )); then
    echo "Fail $status > 0"
    return "$status" # or whatever
  fi
}

user@computer:~$ test_outerr
$ outerr
err
out
===
# stdout.log content :
<===
out
===>
# stderr.log content :
<===
err
===>
Fail 11 > 0

The answer from @gunn is correct, target="_blank makes the link open in a new tab.

But this can be a security risk for you page; you can read about it here. There is a simple solution for that: adding rel="noopener noreferrer".

<a style={{display: "table-cell"}} href = "someLink" target = "_blank" 
rel = "noopener noreferrer">text</a>

Reason of comments:

1. Comment out elements temporarily rather than removing them, especially if they've been left unfinished.
2. Write notes or reminders to yourself inside your actual HTML documents.
3. Create notes for other scripting languages like JavaScript which requires them

<!-- Everything is invisible  -->

Many times when crawling we run into problems where content that is rendered on the page is generated with Javascript and therefore scrapy is unable to crawl for it (eg. ajax requests, jQuery craziness).

However, if you use Scrapy along with the web testing framework Selenium then we are able to crawl anything displayed in a normal web browser.

Some things to note:

• You must have the Python version of Selenium RC installed for this to work, and you must have set up Selenium properly. Also this is just a template crawler. You could get much crazier and more advanced with things but I just wanted to show the basic idea. As the code stands now you will be doing two requests for any given url. One request is made by Scrapy and the other is made by Selenium. I am sure there are ways around this so that you could possibly just make Selenium do the one and only request but I did not bother to implement that and by doing two requests you get to crawl the page with Scrapy too.

• This is quite powerful because now you have the entire rendered DOM available for you to crawl and you can still use all the nice crawling features in Scrapy. This will make for slower crawling of course but depending on how much you need the rendered DOM it might be worth the wait.

ListenForClients is getting invoked twice (on two different threads) - once from the constructor, once from the explicit method call in Main. When two instances of the TcpListener try to listen on the same port, you get that error.

You could use Directory.GetCurrentDirectory:

var path = Path.Combine(Directory.GetCurrentDirectory(), "\\fileName.txt");

Which will look for the file fileName.txt in the current directory of the application.

Try to add export PATH=$PATH:/home/me/play in ~/.bashrc file.

C++11 added alias declarations, which are generalization of typedef, allowing templates:

template <size_t N>
using Vector = Matrix<N, 1>;

The type Vector<3> is equivalent to Matrix<3, 1>.

In C++03, the closest approximation was:

template <size_t N>
struct Vector
{
    typedef Matrix<N, 1> type;
};

Here, the type Vector<3>::type is equivalent to Matrix<3, 1>.

You can also specify the color range and select whether or not to drop duplicate correlations. Notice that I've used the same numbers as you, but that I've put them in a pandas dataframe. Regarding the choice of colors you can have a look at the documents for sns.diverging_palette. You asked for blue, but that falls out of this particular range of the color scale with your sample data. For both observations of 0.95173379, try changing to -0.95173379 and you'll get this:

@font-face {
    font-family: Kaffeesatz;
    src: url(YanoneKaffeesatz-Thin.otf);
    font-weight: 200;
}

    src: url(YanoneKaffeesatz-Light.otf);
    font-weight: 300;
}
@font-face {

    src: url(YanoneKaffeesatz-Regular.otf);
    font-weight: normal;
}
@font-face {

    src: url(YanoneKaffeesatz-Bold.otf);
    font-weight: bold;
}
h3, h4, h5, h6 {
    font-size:2em;
    margin:0;
    padding:0;
    font-family:Kaffeesatz;

}
h6 { font-weight:200; }
h5 { font-weight:300; }
h4 { font-weight:normal; }
h3 { font-weight:bold; }

Is this what you had in mind?

$("document").ready( function() {
    // do your stuff

SQL Server recognizes 'TRUE' and 'FALSE' as bit values. So, use a bit data type!

declare @var bit
set @var = 'true'
print @var

That returns 1.

Regular expressions are simple enough, if you know them.

import re
s = "string. With. Punctuation?"
s = re.sub(r'[^\w\s]','',s)

Inline tag is used to add another src of document to the current html element.

In your case an video of a youtube and we need to specify the html type(4 or 5) to the browser externally to the link

so add ?html=5 to the end of the link.. :)

... You can then use copy() to duplicate a PHP file, although this sounds incredibly inefficient.

The CP1 means 'Code Page 1' - technically this translates to code page 1252

The following code sample, will match the pattern even in case of space characters in between. i.e. :

<td><a href='/path/to/file'>Name of File</a></td>

as well as:

<td> <a      href='/path/to/file' >Name of File</a>  </td>

Method returns true or false, depending on whether the input htmlTd string matches the pattern or no. If it matches, the out params contain the link and name respectively.

/// <summary>
/// Assigns proper values to link and name, if the htmlId matches the pattern
/// </summary>
/// <returns>true if success, false otherwise</returns>
public static bool TryGetHrefDetails(string htmlTd, out string link, out string name)
{
    link = null;
    name = null;

    string pattern = "<td>\\s*<a\\s*href\\s*=\\s*(?:\"(?<link>[^\"]*)\"|(?<link>\\S+))\\s*>(?<name>.*)\\s*</a>\\s*</td>";

    if (Regex.IsMatch(htmlTd, pattern))
    {
        Regex r = new Regex(pattern,  RegexOptions.IgnoreCase | RegexOptions.Compiled);
        link = r.Match(htmlTd).Result("${link}");
        name = r.Match(htmlTd).Result("${name}");
        return true;
    }
    else
        return false;
}

I have tested this and it works correctly.

Jesse Beder's solution is likely the best, but if you don't like the names typeid gives you (I think gcc gives you mangled names for instance), you can do something like:

template<typename T>
struct TypeParseTraits;

#define REGISTER_PARSE_TYPE(X) template <> struct TypeParseTraits<X> \
    { static const char* name; } ; const char* TypeParseTraits<X>::name = #X


REGISTER_PARSE_TYPE(int);
REGISTER_PARSE_TYPE(double);
REGISTER_PARSE_TYPE(FooClass);
// etc...

And then use it like

throw ParseError(TypeParseTraits<T>::name);

EDIT:

You could also combine the two, change name to be a function that by default calls typeid(T).name() and then only specialize for those cases where that's not acceptable.

Variables:

static variables exist for the "lifetime" of the translation unit that it's defined in, and:

• If it's in a namespace scope (i.e. outside of functions and classes), then it can't be accessed from any other translation unit. This is known as "internal linkage" or "static storage duration". (Don't do this in headers except for constexpr. Anything else, and you end up with a separate variable in each translation unit, which is crazy confusing)
• If it's a variable in a function, it can't be accessed from outside of the function, just like any other local variable. (this is the local they mentioned)
• class members have no restricted scope due to static, but can be addressed from the class as well as an instance (like std::string::npos). [Note: you can declare static members in a class, but they should usually still be defined in a translation unit (cpp file), and as such, there's only one per class]

locations as code:

static std::string namespaceScope = "Hello";
void foo() {
    static std::string functionScope= "World";
}
struct A {
   static std::string classScope = "!";
};

Before any function in a translation unit is executed (possibly after main began execution), the variables with static storage duration (namespace scope) in that translation unit will be "constant initialized" (to constexpr where possible, or zero otherwise), and then non-locals are "dynamically initialized" properly in the order they are defined in the translation unit (for things like std::string="HI"; that aren't constexpr). Finally, function-local statics will be initialized the first time execution "reaches" the line where they are declared. All static variables all destroyed in the reverse order of initialization.

The easiest way to get all this right is to make all static variables that are not constexpr initialized into function static locals, which makes sure all of your statics/globals are initialized properly when you try to use them no matter what, thus preventing the static initialization order fiasco.

T& get_global() {
    static T global = initial_value();
    return global;
}

Be careful, because when the spec says namespace-scope variables have "static storage duration" by default, they mean the "lifetime of the translation unit" bit, but that does not mean it can't be accessed outside of the file.

Functions

Significantly more straightforward, static is often used as a class member function, and only very rarely used for a free-standing function.

A static member function differs from a regular member function in that it can be called without an instance of a class, and since it has no instance, it cannot access non-static members of the class. Static variables are useful when you want to have a function for a class that definitely absolutely does not refer to any instance members, or for managing static member variables.

struct A {
    A() {++A_count;}
    A(const A&) {++A_count;}
    A(A&&) {++A_count;}
    ~A() {--A_count;}

    static int get_count() {return A_count;}
private:
    static int A_count;
}

int main() {
    A var;

    int c0 = var.get_count(); //some compilers give a warning, but it's ok.
    int c1 = A::get_count(); //normal way
}

A static free-function means that the function will not be referred to by any other translation unit, and thus the linker can ignore it entirely. This has a small number of purposes:

• Can be used in a cpp file to guarantee that the function is never used from any other file.
• Can be put in a header and every file will have it's own copy of the function. Not useful, since inline does pretty much the same thing.
• Speeds up link time by reducing work
• Can put a function with the same name in each translation unit, and they can all do different things. For instance, you could put a static void log(const char*) {} in each cpp file, and they could each all log in a different way.

I am late to the game but, just in case anybody needs it, this a function I use to make adjustments on my code so it runs on Windows, Linux and MacOs:

import sys
def get_os(osoptions={'linux':'linux','Windows':'win','macos':'darwin'}):
    '''
    get OS to allow code specifics
    '''   
    opsys = [k for k in osoptions.keys() if sys.platform.lower().find(osoptions[k].lower()) != -1]
    try:
        return opsys[0]
    except:
        return 'unknown_OS'

Please make sure you have downloaded the sqldump fully, this problem is very common when we try to import half/incomplete downloaded sqldump. Please check size of your sqldump file.

I feel the simplest way would be

 from matplotlib import pyplot;
 from pylab import genfromtxt;  
 mat0 = genfromtxt("data0.txt");
 mat1 = genfromtxt("data1.txt");
 pyplot.plot(mat0[:,0], mat0[:,1], label = "data0");
 pyplot.plot(mat1[:,0], mat1[:,1], label = "data1");
 pyplot.legend();
 pyplot.show();

1. label is the string that is displayed on the legend
2. you can plot as many series of data points as possible before show() to plot all of them on the same graph This is the simple way to plot simple graphs. For other options in genfromtxt go to this url.

Try this:

Declare @DayOfMonth TinyInt Set @DayOfMonth = 13
Declare @Month TinyInt Set @Month = 6
Declare @Year Integer Set @Year = 2006
-- ------------------------------------
Select DateAdd(day, @DayOfMonth - 1, 
          DateAdd(month, @Month - 1, 
              DateAdd(Year, @Year-1900, 0)))

It works as well, has added benefit of not doing any string conversions, so it's pure arithmetic processing (very fast) and it's not dependent on any date format This capitalizes on the fact that SQL Server's internal representation for datetime and smalldatetime values is a two part value the first part of which is an integer representing the number of days since 1 Jan 1900, and the second part is a decimal fraction representing the fractional portion of one day (for the time) --- So the integer value 0 (zero) always translates directly into Midnight morning of 1 Jan 1900...

or, thanks to suggestion from @brinary,

Select DateAdd(yy, @Year-1900,  
       DateAdd(m,  @Month - 1, @DayOfMonth - 1)) 

Edited October 2014. As Noted by @cade Roux, SQL 2012 now has a built-in function:
DATEFROMPARTS(year, month, day)
that does the same thing.

Edited 3 Oct 2016, (Thanks to @bambams for noticing this, and @brinary for fixing it), The last solution, proposed by @brinary. does not appear to work for leap years unless years addition is performed first

select dateadd(month, @Month - 1, 
     dateadd(year, @Year-1900, @DayOfMonth - 1)); 

Use where with a != operator in combination with whereNull

Code::where('to_be_used_by_user_id', '!=' , 2)->orWhereNull('to_be_used_by_user_id')->get()

just for modifying certain property from object collection you could directly use forEach with a collection as follows

collection.forEach(c -> c.setXyz(c.getXyz + "a"))

Generally a cosine similarity between two documents is used as a similarity measure of documents. In Java, you can use Lucene (if your collection is pretty large) or LingPipe to do this. The basic concept would be to count the terms in every document and calculate the dot product of the term vectors. The libraries do provide several improvements over this general approach, e.g. using inverse document frequencies and calculating tf-idf vectors. If you are looking to do something copmlex, LingPipe also provides methods to calculate LSA similarity between documents which gives better results than cosine similarity. For Python, you can use NLTK.

You can use urllib2

import urllib2
content = urllib2.urlopen(some_url).read()
print content

Also you can use httplib

import httplib
conn = httplib.HTTPConnection("www.python.org")
conn.request("HEAD","/index.html")
res = conn.getresponse()
print res.status, res.reason
# Result:
200 OK

or the requests library

import requests
r = requests.get('https://api.github.com/user', auth=('user', 'pass'))
r.status_code
# Result:
200

This doesn't seem to be relevant in this case, but in case others face this problem --- make sure that if you installed 32 bit version of Eclipse, you also installed 32 bit version of JRE. Similarly, if you installed 64 bit version of Eclipse, you need 64 bit version of JRE in your Windows. Otherwise you will see the above error message as well.

In jstl we can access the current URL path using pageContext.request.contextPath. If you want to do an Ajax call, use the following URL.

url = "${pageContext.request.contextPath}" + "/controller/path"

Example: For the page http://stackoverflow.com/posts/36577223 this will give http://stackoverflow.com/controller/path.

Try this:

new String(bytebuffer.array(), "ASCII");

NB. you can't correctly convert a byte array to a String without knowing its encoding.

I hope this helps

Have not tested it yet, but the looks are better than the one Alex mentions.

The description at winginx.com/en/htaccess says:

About the htaccess to nginx converter

The service is to convert an Apache's .htaccess to nginx configuration instructions.

First of all, the service was thought as a mod_rewrite to nginx converter. However, it allows you to convert some other instructions that have reason to be ported from Apache to nginx.

Note server instructions (e.g. php_value, etc.) are ignored.

The converter does not check syntax, including regular expressions and logic errors.

Please, check the result manually before use.

1· Do I need these DLL's?

It depends since Dependency Walker is a little bit out of date and may report the wrong dependency.

2. Where can I get them?

most dlls can be found at https://www.dll-files.com

I believe they are supposed to located in C:\Windows\System32\Wer.dll and C:\Program Files\Internet Explorer\Ieshims.dll

For me leshims.dll can be placed at C:\Windows\System32\. Context: windows 7 64bit.

Just two more things I found helpful to know, even if they are not part of the question, really.

You can use the relayEvents method to tell a component to listen for certain events of another component and then fire them again as if they originate from the first component. The API docs give the example of a grid relaying the store load event. It is quite handy when writing custom components that encapsulate several sub-components.

The other way around, i.e. passing on events received by an encapsulating component mycmp to one of its sub-components subcmp, can be done like this

mycmp.on('show' function (mycmp, eOpts)
{
   mycmp.subcmp.fireEvent('show', mycmp.subcmp, eOpts);
});

Drop the hash - that's for identifying the id attribute.

Besides the methods described in other answers (sp_depends system stored procedure, SQL Server dynamic management functions) you can also view dependencies between SQL Server objects - from SSMS.

You can use the View Dependencies option from SSMS. From the Object Explorer pane, right click on the object and from the context menu, select the View Dependencies option

I myself prefer a 3rd party dependency viewer called ApexSQL Search. It is a free add-in, which integrates into SSMS and Visual Studio for SQL object and data text search, extended property management, safe object rename, and relationship visualization.

To strip any whitespace, you can use a regular expression

$str=preg_replace('/\s+/', '', $str);

See also this answer for something which can handle whitespace in UTF-8 strings.

Do not hesitate to put constraints on the database. You'll be sure to have a consistent database, and that's one of the good reasons to use a database. Especially if you have several applications requesting it (or just one application but with a direct mode and a batch mode using different sources).

With MySQL you do not have advanced constraints like you would have in postgreSQL but at least the foreign key constraints are quite advanced.

We'll take an example, a company table with a user table containing people from theses company

CREATE TABLE COMPANY (
     company_id INT NOT NULL,
     company_name VARCHAR(50),
     PRIMARY KEY (company_id)
) ENGINE=INNODB;

CREATE TABLE USER (
     user_id INT, 
     user_name VARCHAR(50), 
     company_id INT,
     INDEX company_id_idx (company_id),
     FOREIGN KEY (company_id) REFERENCES COMPANY (company_id) ON...
) ENGINE=INNODB;

Let's look at the ON UPDATE clause:

• ON UPDATE RESTRICT : the default : if you try to update a company_id in table COMPANY the engine will reject the operation if one USER at least links on this company.
• ON UPDATE NO ACTION : same as RESTRICT.
• ON UPDATE CASCADE : the best one usually : if you update a company_id in a row of table COMPANY the engine will update it accordingly on all USER rows referencing this COMPANY (but no triggers activated on USER table, warning). The engine will track the changes for you, it's good.
• ON UPDATE SET NULL : if you update a company_id in a row of table COMPANY the engine will set related USERs company_id to NULL (should be available in USER company_id field). I cannot see any interesting thing to do with that on an update, but I may be wrong.

And now on the ON DELETE side:

• ON DELETE RESTRICT : the default : if you try to delete a company_id Id in table COMPANY the engine will reject the operation if one USER at least links on this company, can save your life.
• ON DELETE NO ACTION : same as RESTRICT
• ON DELETE CASCADE : dangerous : if you delete a company row in table COMPANY the engine will delete as well the related USERs. This is dangerous but can be used to make automatic cleanups on secondary tables (so it can be something you want, but quite certainly not for a COMPANY<->USER example)
• ON DELETE SET NULL : handful : if you delete a COMPANY row the related USERs will automatically have the relationship to NULL. If Null is your value for users with no company this can be a good behavior, for example maybe you need to keep the users in your application, as authors of some content, but removing the company is not a problem for you.

usually my default is: ON DELETE RESTRICT ON UPDATE CASCADE. with some ON DELETE CASCADE for track tables (logs--not all logs--, things like that) and ON DELETE SET NULL when the master table is a 'simple attribute' for the table containing the foreign key, like a JOB table for the USER table.

Edit

It's been a long time since I wrote that. Now I think I should add one important warning. MySQL has one big documented limitation with cascades. Cascades are not firing triggers. So if you were over confident enough in that engine to use triggers you should avoid cascades constraints.

• http://dev.mysql.com/doc/refman/5.6/en/triggers.html

MySQL triggers activate only for changes made to tables by SQL statements. They do not activate for changes in views, nor by changes to tables made by APIs that do not transmit SQL statements to the MySQL Server

• http://dev.mysql.com/doc/refman/5.6/en/stored-program-restrictions.html#stored-routines-trigger-restrictions

==> See below the last edit, things are moving on this domain

Triggers are not activated by foreign key actions.

And I do not think this will get fixed one day. Foreign key constraints are managed by the InnoDb storage and Triggers are managed by the MySQL SQL engine. Both are separated. Innodb is the only storage with constraint management, maybe they'll add triggers directly in the storage engine one day, maybe not.

But I have my own opinion on which element you should choose between the poor trigger implementation and the very useful foreign keys constraints support. And once you'll get used to database consistency you'll love PostgreSQL.

12/2017-Updating this Edit about MySQL:

as stated by @IstiaqueAhmed in the comments, the situation has changed on this subject. So follow the link and check the real up-to-date situation (which may change again in the future).

Have you checked this http://support.microsoft.com/kb/209805? In particular, whether you have Msrd3x40.dll.

You may also like to check that you have the latest version of Jet: http://support.microsoft.com/kb/239114

If you are sending this back to asp.net and need the data in request.form[] then you'll need to set the content type to "application/x-www-form-urlencoded; charset=utf-8"

Secondly get rid of the Datatype, if your not expecting a return the POST will wait for about 4 minutes before failing. See here

Here are my two cents:

function stringFormat(str) {
  if (str !== undefined && str !== null) {
    str = String(str);
    if (str.trim() !== "") {
      var args = arguments;
      return str.replace(/(\{[^}]+\})/g, function(match) {
        var n = +match.slice(1, -1);
        if (n >= 0 && n < args.length - 1) {
          var a = args[n + 1];
          return (a !== undefined && a !== null) ? String(a) : "";
        }
        return match;
      });
    }
  }
  return "";
}

alert(stringFormat("{1}, {0}. You're looking {2} today.",
  "Dave", "Hello", Math.random() > 0.5 ? "well" : "good"));

C++ doesn't allow non-constant values for the size of an array. That's just the way it was designed.

C99 allows the size of an array to be a variable, but I'm not sure it is allowed for two dimensions. Some C++ compilers (gcc) will allow this as an extension, but you may need to turn on a compiler option to allow it.

And I almost missed it - you need to declare a variable name, not just the array dimensions.

First, you have to create your own inline TS-Class, since the FormData Class is not well supported at the moment:

var data : {
  name: string;
  file: File;
} = {
  name: "Name",
  file: inputValue.files[0]
  };

Then you send it to the Server with JSON.stringify(data)

let opts: RequestOptions = new RequestOptions();
opts.method = RequestMethods.Post;
opts.headers = headers;
this.http.post(url,JSON.stringify(data),opts);

There are other database systems, such as document stores, key value stores, columnar stores, object oriented databases. These are databases too but they are not based on relations (relational theory) ie they are not relational database systems.

So there are lot of differences. Database management system is the name for all databases.

1. PYTHONPATH is an environment variable
2. Yes (see https://unix.stackexchange.com/questions/24802/on-which-unix-distributions-is-python-installed-as-part-of-the-default-install)
3. /usr/lib/python2.7 on Ubuntu
4. you shouldn't install packages manually. Instead, use pip. When a package isn't in pip, it usually has a setuptools setup script which will install the package into the proper location (see point 3).
5. if you use pip or setuptools, then you don't need to set PYTHONPATH explicitly

If you look at the instructions for pyopengl, you'll see that they are consistent with points 4 and 5.

I know that it is a very old post but for the sake of the users who are landed here and looking for a solution, if you are using Cloudflare as your DNS then you can activate IP geolocation and get the value from the request header,

here is the code snippet in C# after you enable IP geolocation in Cloudflare through the network tab

 var countryCode = HttpContext.Request.Headers.Get("cf-ipcountry"); // in older asp.net versions like webform use HttpContext.Current.Request. ...
 var countryName = new RegionInfo(CountryCode)?.EnglishName;

you can simply map it to other programming languages, please take a look at the Cloudflare's documentation here

but if you are really insisting on using a 3rd party solution to have more precise information about the visitors using their IP here is a complete, ready to use implementation using C#:

the 3rd party I have used is https://ipstack.com, you can simply register for a free plan and get an access token to use for 10K API requests each month, I am using the JSON model to retrieve and like to convert all the info the API gives me, here we go:

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

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

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

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

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

Using Widget.AppCompat.RatingBar, you have 2 styles to use; Indicator and Small for large and small sizes respectively. See example below.

<RatingBar
    android:id="@+id/rating_star_value"
    style="@style/Widget.AppCompat.RatingBar.Small"
    ... />

Use This Code anywhere in class or libraries

    $current_url =& get_instance(); //  get a reference to CodeIgniter
    $current_url->router->fetch_class(); // for Class name or controller
    $current_url->router->fetch_method(); // for method name

There are two ways you can count the number of rows.

$query = "SELECT count(*) as total from table1";
$prepare = $link->prepare($query);
$prepare->execute();
$row = $prepare->fetch(PDO::FETCH_ASSOC);
echo $row['total']; // This will return you a number of rows.

Or second way is

$query = "SELECT field1, field2 from table1";
$prepare = $link->prepare($query);
$prepare->execute();
$row = $prepare->fetch(PDO::FETCH_NUM);
echo $rows[0]; // This will return you a number of rows as well.

Robot robot = new Robot();
robot.mouseMove(coordinates.x,coordinates.y+80);

Rotbot is good solution. It works for me.

First you split the values of two input box by using split function. then concat the same in reverse order. after concat nation parse it to integer. then compare two values in in if statement. eg.1>20-11-2018 2>21-11-2018

after split and concat new values for comparison 20181120 and 20181121 the after that compare the same.

var date1 = $('#datevalue1').val();
var date2 = $('#datevalue2').val();
var d1 = date1.split("-");
var d2 = date2.split("-");

d1 = d1[2].concat(d1[1], d1[0]);
d2 = d2[2].concat(d2[1], d2[0]);

if (parseInt(d1) > parseInt(d2)) {

    $('#fromdatepicker').val('');
} else {

}

Yeah, when ASP.NET web.config gets updated, the whole application gets restarted which means the web.config gets reloaded.

For people coming from Google, this question is not about data attributes - OP added a non-standard attribute to their HTML object, and wondered how to set it.

However, you should not add custom attributes to your properties - you should use data attributes - e.g. OP should have used data-icon, data-url, data-target, etc.

In any event, it turns out that the way you set these attributes via JavaScript is the same for both cases. Use:

ele.setAttribute(attributeName, value);

to change the given attribute attributeName to value for the DOM element ele.

For example:

document.getElementById("someElement").setAttribute("data-id", 2);

Note that you can also use .dataset to set the values of data attributes, but as @racemic points out, it is 62% slower (at least in Chrome on macOS at the time of writing). So I would recommend using the setAttribute method instead.

Check out http://codepad.org. It probably won't solve the poster's problem; but, I think it will be of use to others who read this article.

If you take a look at bootstrap source codes, you will notice that position can be modified using margin.

So, first you should change popover template to add own css class to not get in conflict with other popovers:

$(".trigger").popover({
  html: true,
  placement: 'bottom',
  trigger: 'click',
  template: '<div class="popover popover--topright" role="tooltip"><div class="arrow"></div><h3 class="popover-title"></h3><div class="popover-content"></div></div>'
});

Then using css you can easily shift popover position:

.popover.popover--topright {
  /* margin-top: 0px; // Use to change vertical position */
  margin-right: 40px; /* Use to change horizontal position */
}
.popover.popover--topright .arrow {
  left: 88% !important; /* fix arrow position */
}

This solution would not influence other popovers you have. Same solution can be used on tooltips as well because popover class inherit from tooltip class.

Here's a simple jsFiddle

There are many tutorials and answers here how to add your script to be included in the page. But what I couldn't find is how to structure that code so it will work properly. This is due the $ being not used in this form of JQuery.

So here is my code and you can use that as a template.

jQuery(document).ready(function( $ ){
  $("#btnCalculate").click(function () {
        var val1 = $(".visits").val();
        var val2 = $(".collection").val();
        var val3 = $(".percent").val();
        var val4 = $(".expired").val();
        var val5 = $(".payer").val();
        var val6 = $(".deductible").val(); 
        var result = val1 * (val3 / 100) * 10 * 0.25;
        var result2 = val1 * val2 * (val4 / 100) * 0.2;
        var result3 = val1 * val2 * (val5 / 100) * 0.2;
        var result4 = val1 * val2 * (val6 / 100) * 0.1;
        var val7 = $(".pverify").val();
        var result5 = result + result2 + result3 + result4 - val7;
        var result6 = result5 * 12;
        $("#result").val("$" + result);
        $("#result2").val("$" + result2);
        $("#result3").val("$" + result3);
        $("#result4").val("$" + result4);
        $("#result5").val("$" + result5);
        $("#result6").val("$" + result6);
  });
});

You can use the storage_path(); function to get storage folder path.

storage_path(); // Return path like: laravel_app\storage

Suppose you want to save your logfile mylog.log inside Log folder of storage folder. You have to write something like

storage_path() . '/LogFolder/mylog.log'

Comparable is used to compare instances of your class. We can compare instances from many ways that is why we need to implement a method compareTo in order to know how (attributes) we want to compare instances.

Dog class:

package test;
import java.util.Arrays;

public class Main {

    public static void main(String[] args) {
        Dog d1 = new Dog("brutus");
        Dog d2 = new Dog("medor");
        Dog d3 = new Dog("ara");
        Dog[] dogs = new Dog[3];
        dogs[0] = d1;
        dogs[1] = d2;
        dogs[2] = d3;

        for (int i = 0; i < 3; i++) {
            System.out.println(dogs[i].getName());
        }
        /**
         * Output:
         * brutus
         * medor
         * ara
         */

        Arrays.sort(dogs, Dog.NameComparator);
        for (int i = 0; i < 3; i++) {
            System.out.println(dogs[i].getName());
        }
        /**
         * Output:
         * ara
         * medor
         * brutus
         */

    }
}

Main class:

package test;

import java.util.Arrays;

public class Main {

    public static void main(String[] args) {
        Dog d1 = new Dog("brutus");
        Dog d2 = new Dog("medor");
        Dog d3 = new Dog("ara");
        Dog[] dogs = new Dog[3];
        dogs[0] = d1;
        dogs[1] = d2;
        dogs[2] = d3;

        for (int i = 0; i < 3; i++) {
            System.out.println(dogs[i].getName());
        }
        /**
         * Output:
         * brutus
         * medor
         * ara
         */

        Arrays.sort(dogs, Dog.NameComparator);
        for (int i = 0; i < 3; i++) {
            System.out.println(dogs[i].getName());
        }
        /**
         * Output:
         * ara
         * medor
         * brutus
         */

    }
}

Here is a good example how to use comparable in Java:

http://www.onjava.com/pub/a/onjava/2003/03/12/java_comp.html?page=2

The only way is to highlight the lines to comment and press

ctrl + k, ctrl + c

or after highlighted press the toolbar option to comment out the selected lines.

The icons look like this

I never had any luck with that approach. I always do this (hope this helps):

var obj = {};

obj.first_name = $("#namec").val();
obj.last_name = $("#surnamec").val();
obj.email = $("#emailc").val();
obj.mobile = $("#numberc").val();
obj.password = $("#passwordc").val();

Then in your ajax:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: JSON.stringify(obj),
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
    });

Using LINQ to xml if you are using framework 3.5:

using System.Xml.Linq;

XDocument xmlFile = XDocument.Load("books.xml"); 

var query = from c in xmlFile.Elements("catalog").Elements("book")    
            select c; 

foreach (XElement book in query) 
{
   book.Attribute("attr1").Value = "MyNewValue";
}

xmlFile.Save("books.xml");

First, you know that "blank" and "null" are two COMPLETELY DIFFERENT THINGS? Correct?

Second: in most programming languages, "" means an "empty string". A zero-length string. No characters in it.

SQL doesn't necessarily work like that. If I define a column "name char(5)", then a "blank" name will be " " (5 spaces).

It sounds like you might want something like this:

select count(*) from my_table where Length(trim(my_column)) = 0;

"Trim()" is one of many Oracle functions you can use in PL/SQL. It's documented here:

http://www.techonthenet.com/oracle/functions/trim.php

'Hope that helps!

String arr= "[1,2]";
List<Integer> arrList= JSON.parseArray(arr,Integer.class).stream().collect(Collectors.toList());
Integer[] intArr = ArrayUtils.toObject(arrList.stream().mapToInt(Integer::intValue).toArray());

You can try with the code that is below.

It will make the default date become the date you are looking for.

$('#birthdate').datepicker("setDate", new Date(1985,01,01) );

use the pow function (it takes floats/doubles though).

man pow:

   #include <math.h>

   double pow(double x, double y);
   float powf(float x, float y);
   long double powl(long double x, long double y);

EDIT: For the special case of positive integer powers of 2, you can use bit shifting: (1 << x) will equal 2 to the power x. There are some potential gotchas with this, but generally, it would be correct.

The second function should have:

var value = document.getElementById(id).value;

Then they are basically the same function.

Uninstall tensorflow and install only tensorflow-gpu; this should be sufficient. By default, this should run on the GPU and not the CPU. However, further you can do the following to specify which GPU you want it to run on.

If you have an nvidia GPU, find out your GPU id using the command nvidia-smi on the terminal. After that, add these lines in your script:

os.environ["CUDA_DEVICE_ORDER"] = "PCI_BUS_ID"
os.environ["CUDA_VISIBLE_DEVICES"] = #GPU_ID from earlier

config = tf.ConfigProto()
sess = tf.Session(config=config)

For the functions where you wish to use GPUs, write something like the following:

with tf.device(tf.DeviceSpec(device_type="GPU", device_index=gpu_id)):

Try to use it, and trap for the error. The allowed set may change across file systems, or across different versions of Windows. In other words, if you want know if Windows likes the name, hand it the name and let it tell you.

Here's yet another solution, just for kicks. It's probably not very efficient, but it does cope with both height and width of the text, and with marked-up text.

@Override
protected void onMeasure(final int widthMeasureSpec, final int heightMeasureSpec)
{
    if ((MeasureSpec.getMode(widthMeasureSpec) != MeasureSpec.UNSPECIFIED)
            && (MeasureSpec.getMode(heightMeasureSpec) != MeasureSpec.UNSPECIFIED)) {

        final float desiredWidth = MeasureSpec.getSize(widthMeasureSpec);
        final float desiredHeight = MeasureSpec.getSize(heightMeasureSpec);

        float textSize = getTextSize();
        float lastScale = Float.NEGATIVE_INFINITY;
        while (textSize > MINIMUM_AUTO_TEXT_SIZE_PX) {
            // Measure how big the textview would like to be with the current text size.
            super.onMeasure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);

            // Calculate how much we'd need to scale it to fit the desired size, and
            // apply that scaling to the text size as an estimate of what we need.
            final float widthScale = desiredWidth / getMeasuredWidth();
            final float heightScale = desiredHeight / getMeasuredHeight();
            final float scale = Math.min(widthScale, heightScale);

            // If we don't need to shrink the text, or we don't seem to be converging, we're done.
            if ((scale >= 1f) || (scale <= lastScale)) {
                break;
            }

            // Shrink the text size and keep trying.
            textSize = Math.max((float) Math.floor(scale * textSize), MINIMUM_AUTO_TEXT_SIZE_PX);
            setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize);
            lastScale = scale;
        }
    }
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

If you have access to apache bin directory you can use,

httpd -M to check loaded modules first.

 info_module (shared)
 isapi_module (shared)
 log_config_module (shared)
 cache_disk_module (shared)
 mime_module (shared)
 negotiation_module (shared)
 proxy_module (shared)
 proxy_ajp_module (shared)

 status_module (shared)
 version_module (shared)
 php5_module (shared)

After that simple directives like Options -Indexes or deny from all will solidify that .htaccess are working correctly.

If you already have a list and want to add values from a delimited string, you can use AddRange or InsertRange. For example:

existingList.AddRange(names.Split(','));

or you can simply do

$('select[name=a[b]] option:selected').val()

You can use animate insted of show/hide

Something like this:

function switch_tabs(obj)
{
    $('.tab-content').animate({opacity:0},3000);
    $('.tabs a').removeClass("selected");
    var id = obj.attr("rel");

    $('#'+id).animate({opacity:1},3000);
    obj.addClass("selected");
}

This is somewhat a go around solution but it worked for me I hope it works for this problem for others as well:

You can run the select SQL query on the table that you want to export and save the result as .xls in you drive.

Now create the table you want to add data with all the columns and indexes. This can be easily done with the right click on the actual table and selecting Create To script option.

Now you can right click on the DB where you want to add you table and select the Tasks>Import .

Import Export wizard opens and select next.Select the Microsoft Excel as input Data source and then browse and select the .xls file you have saved earlier.

Now select the destination server and also the destination table we have created already.

Note:If there is any identity based field, in the destination table you might want to remove the identity property as this data will also be inserted . So if you had this one as Identity property only then it would error out the import process.

Now hit next and hit finish and it will show you how many records are being imported and return success if no errors occur.

1. Yes, on most CPUs, SHA-256 is two to three times slower than MD5, though not primarily because of its longer hash. See other answers here and the answers to this Stack Overflow questions.
2. Here's a backup scenario where MD5 would not be appropriate:
   • Your backup program hashes each file being backed up. It then stores each file's data by its hash, so if you're backing up the same file twice you only end up with one copy of it.
   • An attacker can cause the system to backup files they control.
   • The attacker knows the MD5 hash of a file they want to remove from the backup.
   • The attacker can then use the known weaknesses of MD5 to craft a new file that has the same hash as the file to remove. When that file is backed up, it will replace the file to remove, and that file's backed up data will be lost.
   • This backup system could be strengthened a bit (and made more efficient) by not replacing files whose hash it has previously encountered, but then an attacker could prevent a target file with a known hash from being backed up by preemptively backing up a specially constructed bogus file with the same hash.
   • Obviously most systems, backup and otherwise, do not satisfy the conditions necessary for this attack to be practical, but I just wanted to give an example of a situation where SHA-256 would be preferable to MD5. Whether this would be the case for the system you're creating depends on more than just the characteristics of MD5 and SHA-256.
3. Yes, cryptographic hashes like the ones generated by MD5 and SHA-256 are a type of checksum.

Happy hashing!

Why is the <center> tag deprecated in HTML?

The terms "interpreted language" or "compiled language" don't make sense, because any programming language can be interpreted and/or compiled.

As for the existing implementations of Java, most involve a compilation step to bytecode, so they involve compilation. The runtime also can load bytecode dynamically, so some form of a bytecode interpreter is always needed. That interpreter may or may not in turn use compilation to native code internally.

These days partial just-in-time compilation is used for many languages which were once considered "interpreted", for example JavaScript.

The simplest approach is to use ExecutorService.invokeAll() which does what you want in a one-liner. In your parlance, you'll need to modify or wrap ComputeDTask to implement Callable<>, which can give you quite a bit more flexibility. Probably in your app there is a meaningful implementation of Callable.call(), but here's a way to wrap it if not using Executors.callable().

ExecutorService es = Executors.newFixedThreadPool(2);
List<Callable<Object>> todo = new ArrayList<Callable<Object>>(singleTable.size());

for (DataTable singleTable: uniquePhrases) { 
    todo.add(Executors.callable(new ComputeDTask(singleTable))); 
}

List<Future<Object>> answers = es.invokeAll(todo);

As others have pointed out, you could use the timeout version of invokeAll() if appropriate. In this example, answers is going to contain a bunch of Futures which will return nulls (see definition of Executors.callable(). Probably what you want to do is a slight refactoring so you can get a useful answer back, or a reference to the underlying ComputeDTask, but I can't tell from your example.

If it isn't clear, note that invokeAll() will not return until all the tasks are completed. (i.e., all the Futures in your answers collection will report .isDone() if asked.) This avoids all the manual shutdown, awaitTermination, etc... and allows you to reuse this ExecutorService neatly for multiple cycles, if desired.

There are a few related questions on SO:

• How to wait for all threads to finish

• Return values from java threads

• invokeAll() not willing to accept a Collection<Callable<t>>

• Do I need to synchronize?

None of these are strictly on-point for your question, but they do provide a bit of color about how folks think Executor/ExecutorService ought to be used.

Simplest:

Form form = new Form();
form.add("id", "1");    
form.add("name", "supercobra");
ClientResponse response = webResource
  .type(MediaType.APPLICATION_FORM_URLENCODED_TYPE)
  .post(ClientResponse.class, form);

This should work:

 cat "$API" >> "$CONFIG"

You need to use the >> operator to append to a file. Redirecting with > causes the file to be overwritten. (truncated).

you should try with jquery validate plugin :

$('form').validate({
   rules:{
       email:{
          required:true,
          email:true
       }
   },
   messages:{
       email:{
          required:"Email is required",
          email:"Please type a valid email"
        }
   }
})

Its fine to just do char **strings;, char **strings = NULL, or char **strings = {NULL}

but to initialize it you'd have to use malloc:

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

int main(){
    // allocate space for 5 pointers to strings
    char **strings = (char**)malloc(5*sizeof(char*));
    int i = 0;
    //allocate space for each string
    // here allocate 50 bytes, which is more than enough for the strings
    for(i = 0; i < 5; i++){
        printf("%d\n", i);
        strings[i] = (char*)malloc(50*sizeof(char));
    }
    //assign them all something
    sprintf(strings[0], "bird goes tweet");
    sprintf(strings[1], "mouse goes squeak");
    sprintf(strings[2], "cow goes moo");
    sprintf(strings[3], "frog goes croak");
    sprintf(strings[4], "what does the fox say?");
    // Print it out
    for(i = 0; i < 5; i++){
        printf("Line #%d(length: %lu): %s\n", i, strlen(strings[i]),strings[i]);
    } 
    //Free each string
    for(i = 0; i < 5; i++){
        free(strings[i]);
    }
    //finally release the first string
    free(strings);
    return 0;
}

TL;DR If you have very simple scenarios, like a single client application, a single API then it might not pay off to go OAuth 2.0, on the other hand, lots of different clients (browser-based, native mobile, server-side, etc) then sticking to OAuth 2.0 rules might make it more manageable than trying to roll your own system.

As stated in another answer, JWT (Learn JSON Web Tokens) is just a token format, it defines a compact and self-contained mechanism for transmitting data between parties in a way that can be verified and trusted because it is digitally signed. Additionally, the encoding rules of a JWT also make these tokens very easy to use within the context of HTTP.

Being self-contained (the actual token contains information about a given subject) they are also a good choice for implementing stateless authentication mechanisms (aka Look mum, no sessions!). When going this route and the only thing a party must present to be granted access to a protected resource is the token itself, the token in question can be called a bearer token.

In practice, what you're doing can already be classified as based on bearer tokens. However, do consider that you're not using bearer tokens as specified by the OAuth 2.0 related specs (see RFC 6750). That would imply, relying on the Authorization HTTP header and using the Bearer authentication scheme.

Regarding the use of the JWT to prevent CSRF without knowing exact details it's difficult to ascertain the validity of that practice, but to be honest it does not seem correct and/or worthwhile. The following article (Cookies vs Tokens: The Definitive Guide) may be a useful read on this subject, particularly the XSS and XSRF Protection section.

One final piece of advice, even if you don't need to go full OAuth 2.0, I would strongly recommend on passing your access token within the Authorization header instead of going with custom headers. If they are really bearer tokens, follow the rules of RFC 6750. If not, you can always create a custom authentication scheme and still use that header.

Authorization headers are recognized and specially treated by HTTP proxies and servers. Thus, the usage of such headers for sending access tokens to resource servers reduces the likelihood of leakage or unintended storage of authenticated requests in general, and especially Authorization headers.

(source: RFC 6819, section 5.4.1)

Regarding the question,

” can someone explain why the compare() function exists if a comparison can be made using simple operands?

Relative to < and ==, the compare function is conceptually simpler and in practice it can be more efficient since it avoids two comparisons per item for ordinary ordering of items.

As an example of simplicity, for small integer values you can write a compare function like this:

auto compare( int a, int b ) -> int { return a - b; }

which is highly efficient.

Now for a structure

struct Foo
{
    int a;
    int b;
    int c;
};

auto compare( Foo const& x, Foo const& y )
    -> int
{
    if( int const r = compare( x.a, y.a ) ) { return r; }
    if( int const r = compare( x.b, y.b ) ) { return r; }
    return compare( x.c, y.c );
}

Trying to express this lexicographic compare directly in terms of < you wind up with horrendous complexity and inefficiency, relatively speaking.

With C++11, for the simplicity alone ordinary less-than comparison based lexicographic compare can be very simply implemented in terms of tuple comparison.

UPDATE `table_name` SET `test` = `number`

You can also do any mathematical changes in the process or use MySQL functions to modify the values.

There are various causes of segmentation faults, but fundamentally, you are accessing memory incorrectly. This could be caused by dereferencing a null pointer, or by trying to modify readonly memory, or by using a pointer to somewhere that is not mapped into the memory space of your process (that probably means you are trying to use a number as a pointer, or you incremented a pointer too far). On some machines, it is possible for a misaligned access via a pointer to cause the problem too - if you have an odd address and try to read an even number of bytes from it, for example (that can generate SIGBUS, instead).

Use tail command:

ls -t | tail -n 5

add android:focusableInTouchMode="true" in root layout, when edit text will be clicked at that time cursor will be shown.

Works, just figured this out a week ago, and just now got to testing it.

double theta = Math.atan2(cir.getX()-sqr.getX()*1.0,
                          cir.getY()-sqr.getY()*1.0); //radians of the angle
double dBox; //distance from box to edge of box in direction of the circle

if((theta >  Math.PI/4 && theta <  3*Math.PI / 4) ||
   (theta < -Math.PI/4 && theta > -3*Math.PI / 4)) {
    dBox = sqr.getS() / (2*Math.sin(theta));
} else {
    dBox = sqr.getS() / (2*Math.cos(theta));
}
boolean touching = (Math.abs(dBox) >=
                    Math.sqrt(Math.pow(sqr.getX()-cir.getX(), 2) +
                              Math.pow(sqr.getY()-cir.getY(), 2)));

Set your Textbox value in a string like:

string MySTring = textBox1.Text;

Then replace your string. For example, replace "Text" with "Hex":

MyString = MyString.Replace("Text", "Hex");

Or for your problem (replace "," with ;) :

MyString = MyString.Replace(@""",""", ",");

Note: If you have "" in your string you have to use @ in the back of "", like:

@"","";

I personally use

myVar === undefined

Warning: Please note that === is used over == and that myVar has been previously declared (not defined).

I do not like typeof myVar === "undefined". I think it is long winded and unnecessary. (I can get the same done in less code.)

Now some people will keel over in pain when they read this, screaming: "Wait! WAAITTT!!! undefined can be redefined!"

Cool. I know this. Then again, most variables in Javascript can be redefined. Should you never use any built-in identifier that can be redefined?

If you follow this rule, good for you: you aren't a hypocrite.

The thing is, in order to do lots of real work in JS, developers need to rely on redefinable identifiers to be what they are. I don't hear people telling me that I shouldn't use setTimeout because someone can

window.setTimeout = function () {
    alert("Got you now!");
};

Bottom line, the "it can be redefined" argument to not use a raw === undefined is bogus.

(If you are still scared of undefined being redefined, why are you blindly integrating untested library code into your code base? Or even simpler: a linting tool.)

Also, like the typeof approach, this technique can "detect" undeclared variables:

if (window.someVar === undefined) {
    doSomething();
}

But both these techniques leak in their abstraction. I urge you not to use this or even

if (typeof myVar !== "undefined") {
    doSomething();
}

Consider:

var iAmUndefined;

To catch whether or not that variable is declared or not, you may need to resort to the in operator. (In many cases, you can simply read the code O_o).

if ("myVar" in window) {
    doSomething();
}

But wait! There's more! What if some prototype chain magic is happening…? Now even the superior in operator does not suffice. (Okay, I'm done here about this part except to say that for 99% of the time, === undefined (and ****cough**** typeof) works just fine. If you really care, you can read about this subject on its own.)

That is the simple way of converting string into util date and sql date

String startDate="12-31-2014";
SimpleDateFormat sdf1 = new SimpleDateFormat("MM-dd-yyyy");
java.util.Date date = sdf1.parse(startDate);
java.sql.Date sqlStartDate = new java.sql.Date(date.getTime()); 

I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).

Read my answer there for a fuller explaination, but in short:

• They removed it deliberately, because compat mode is not actually really very good for testing compatibility.

• If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.

• The only way to get compat mode in IE11 is to set the X-UA-Compatible header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.

The push command has a -n/--dry-run option which will compute what needs to be pushed but not actually do it. Does that work for you?

On C++17 you can by this way :

#include <filesystem>
#include <iostream>
#include <vector>
namespace fs = std::filesystem;

int main()
{
    std::ios_base::sync_with_stdio(false);
    for (const auto &entry : fs::recursive_directory_iterator(".")) {
        if (entry.path().extension() == ".png") {
            std::cout << entry.path().string() << std::endl;
            
        }
    }
    return 0;
}

To expand on what has been provided for automatically exporting data as csv to a network share via SQL Server Agent.

(1) Enable the xp_cmdshell procedure:

-- To allow advanced options to be changed.
EXEC sp_configure 'show advanced options', 1
RECONFIGURE
GO

-- Enable the xp_cmdshell procedure
EXEC sp_configure 'xp_cmdshell', 1
RECONFIGURE
GO

(2) Create a login 'Domain\TestUser' (windows user) for the non-sysadmin user that has public access to the master database. Done through user mapping

(3) Give log on as batch job: Navigate to Local Security Policy -> Local Policies -> User Rights Assignment. Add user to "Log on as a batch job"

(4) Give read/write permissions to network folder for domain\user

(5) Grant EXEC permission on the xp_cmdshell stored procedure:

GRANT EXECUTE ON xp_cmdshell TO [Domain\TestUser]

(6) Create a proxy account that xp_cmdshell will be run under using sp_xp_cmdshell_proxy_account

EXEC sp_xp_cmdshell_proxy_account 'Domain\TestUser', 'password_for_domain_user'

(7) If the sp_xp_cmdshell_proxy_account command doesn't work, manually create it

create credential ##xp_cmdshell_proxy_account## with identity = 'Domain\DomainUser', secret = 'password'

(8) Enable SQL Server Agent. Open SQL Server Configuration Manager, navigate to SQL Server Services, enable SQL Server Agent.

(9) Create automated job. Open SSMS, select SQL Server Agent, then right-click jobs and click "New Job".

(10) Select "Owner" as your created user. Select "Steps", make "type" = T-SQL. Fill out command field similar to below. Set delimiter as ','

EXEC master..xp_cmdshell 'SQLCMD -q "select * from master" -o file.csv -s "," 

(11) Fill out schedules accordingly.

The simple answer is yes - new() creates an object on the heap (with the unfortunate side effect that you have to manage its lifetime (by explicitly calling delete on it), whereas the second form creates an object in the stack in the current scope and that object will be destroyed when it goes out of scope.

Any of the above solutions didn't work for me. I got ModuleNotFoundError: No module named whtever error. So my solution was importing like below

from . import filename # without .py  

inside my first file I have defined function fun like below

# file name is firstFile.py
def fun():
  print('this is fun')

inside the second file lets say I want to call the function fun

from . import firstFile

def secondFunc():
   firstFile.fun() # calling `fun` from the first file

secondFunc() # calling the function `secondFunc` 

I encountered the same error. My linker command did have the rt library included -lrt which is correct and it was working for a while. After re-installing Kubuntu it stopped working.

A separate forum thread suggested the -lrt needed to come after the project object files. Moving the -lrt to the end of the command fixed this problem for me although I don't know the details of why.

Statements before could change the state of our Python program: create or update variables, define function, etc.

And expressions just return some value can't change the global state or local state in a function.

But now we got :=, it's an alien!

Developed this method:

You NEED a table that has an unique value that can be ordered.

If you want rows 10,000 to 25,000 and your Table has 40,000 rows, first you need to get the starting point and total rows:

int start = 40000 - 10000;

int total = 25000 - 10000;

And then pass these by code to the query:

SELECT * FROM 
(SELECT * FROM schema.mytable 
ORDER BY userId DESC fetch first {start} rows only ) AS mini 
ORDER BY mini.userId ASC fetch first {total} rows only

You are using a forward declaration for the type MainWindowClass. That's fine, but it also means that you can only declare a pointer or reference to that type. Otherwise the compiler has no idea how to allocate the parent object as it doesn't know the size of the forward declared type (or if it actually has a parameterless constructor, etc.)

So, you either want:

// forward declaration, details unknown
class A;

class B {
  A *a;  // pointer to A, ok
};

Or, if you can't use a pointer or reference....

// declaration of A
#include "A.h"

class B {
  A a;  // ok, declaration of A is known
};

At some point, the compiler needs to know the details of A.

If you are only storing a pointer to A then it doesn't need those details when you declare B. It needs them at some point (whenever you actually dereference the pointer to A), which will likely be in the implementation file, where you will need to include the header which contains the declaration of the class A.

// B.h
// header file

// forward declaration, details unknown
class A;

class B {
public: 
    void foo();
private:
  A *a;  // pointer to A, ok
};

// B.cpp
// implementation file

#include "B.h"
#include "A.h"  // declaration of A

B::foo() {
    // here we need to know the declaration of A
    a->whatever();
}

Java programming provides wrapper class for each primitive data types, to convert a primitive data types to correspond object of wrapper class.

You can do this instead too:

tasklist | find /I "test.exe" > nul && taskkill /f /im test.exe > nul

datetime.date(2011, 1, 1) < datetime.date(2011, 1, 2) will return True.

datetime.date(2011, 1, 1) - datetime.date(2011, 1, 2) will return datetime.timedelta(-1).

datetime.date(2011, 1, 1) + datetime.date(2011, 1, 2) will return datetime.timedelta(1).

see the docs.

In the early days...like before the 90s...the processors weren't able to do multi tasks that efficiently...coz a single processor could handle just a single task...so when we used to say that my antivirus,microsoft word,vlc,etc. softwares are all running at the same time...that isn't actually true. When I said a processor could handle a single process at a time...I meant it. It actually would process a single task...then it used to pause that task...take another task...complete it if its a short one or again pause it and add it to the queue...then the next. But this 'pause' that I mentioned was so small (appx. 1ns) that you didn't understand that the task has been paused. Eg. On vlc while listening to music there are other apps running simultaneously but as I told you...one program at a time...so the vlc is actually pausing in between for ns so you dont underatand it but the music is actually stopping in between.

But this was about the old processors...

Now-a- days processors ie 3rd gen pcs have multi cored processors. Now the 'cores' can be compared to a 1st or 2nd gen processors itself...embedded onto a single chip, a single processor. So now we understood what are cores ie they are mini processors which combine to become a processor. And each core can handle a single process at a time or multi threads as designed for the OS. And they folloq the same steps as I mentioned above about the single processor.

Eg. A i7 6gen processor has 8 cores...ie 8 mini processors in 1 i7...ie its speed is 8x times the old processors. And this is how multi tasking can be done.

There could be hundreds of cores in a single processor Eg. Intel i128.

I hope I explaned this well.

It lets you define a @Section of code in your template that you can then include in other files. For example, a sidebar defined in the template, could be referenced in another included view.

//This could be used to render a @Section defined as @Section SideBar { ...
@RenderSection("SideBar", required: false);

Hope this helps.

PHP 5.5+

Starting PHP5.5+ you have array_column() available to you, which makes all of the below obsolete.

PHP 5.3+

$ids = array_map(function ($ar) {return $ar['id'];}, $users);

Solution by @phihag will work flawlessly in PHP starting from PHP 5.3.0, if you need support before that, you will need to copy that wp_list_pluck.

PHP < 5.3

In Wordpress there is a function called wp_list_pluck If you're using Wordpress that solves your problem.

If you're not using Wordpress, since the code is open source you can copy paste the code in your project (and rename the function to something you prefer, like array_pick). View source here

Blob is much slower than String.fromCharCode(null,array);

but that fails if the array buffer gets too big. The best solution I have found is to use String.fromCharCode(null,array); and split it up into operations that won't blow the stack, but are faster than a single char at a time.

The best solution for large array buffer is:

function arrayBufferToString(buffer){

    var bufView = new Uint16Array(buffer);
    var length = bufView.length;
    var result = '';
    var addition = Math.pow(2,16)-1;

    for(var i = 0;i<length;i+=addition){

        if(i + addition > length){
            addition = length - i;
        }
        result += String.fromCharCode.apply(null, bufView.subarray(i,i+addition));
    }

    return result;

}

I found this to be about 20 times faster than using blob. It also works for large strings of over 100mb.

Your current implementation is correct. The suggested is not possible but the pseudo code would be implemented with multiple equal() calls and ||.

You can have multiple identical hash keys; but only if you have a range key that varies. Think of it like file formats; you can have 2 files with the same name in the same folder as long as their format is different. If their format is the same, their name must be different. The same concept applies to DynamoDB's hash/range keys; just think of the hash as the name and the range as the format.

Also, I don't recall if they had these at the time of the OP (I don't believe they did), but they now offer Local Secondary Indexes.

My understanding of these is that it should now allow you to perform the desired queries without having to do a full scan. The downside is that these indexes have to be specified at table creation, and also (I believe) cannot be blank when creating an item. In addition, they require additional throughput (though typically not as much as a scan) and storage, so it's not a perfect solution, but a viable alternative, for some.

I do still recommend Mike Brant's answer as the preferred method of using DynamoDB, though; and use that method myself. In my case, I just have a central table with only a hash key as my ID, then secondary tables that have a hash and range that can be queried, then the item points the code to the central table's "item of interest", directly.

Additional data regarding the secondary indexes can be found in Amazon's DynamoDB documentation here for those interested.

Anyway, hopefully this will help anyone else that happens upon this thread.

For Web API 2, you can implement IHttpActionResult. Here's mine:

using System;
using System.IO;
using System.Net;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading;
using System.Threading.Tasks;
using System.Web;
using System.Web.Http;

class FileResult : IHttpActionResult
{
    private readonly string _filePath;
    private readonly string _contentType;

    public FileResult(string filePath, string contentType = null)
    {
        if (filePath == null) throw new ArgumentNullException("filePath");

        _filePath = filePath;
        _contentType = contentType;
    }

    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        var response = new HttpResponseMessage(HttpStatusCode.OK)
        {
            Content = new StreamContent(File.OpenRead(_filePath))
        };

        var contentType = _contentType ?? MimeMapping.GetMimeMapping(Path.GetExtension(_filePath));
        response.Content.Headers.ContentType = new MediaTypeHeaderValue(contentType);

        return Task.FromResult(response);
    }
}

Then something like this in your controller:

[Route("Images/{*imagePath}")]
public IHttpActionResult GetImage(string imagePath)
{
    var serverPath = Path.Combine(_rootPath, imagePath);
    var fileInfo = new FileInfo(serverPath);

    return !fileInfo.Exists
        ? (IHttpActionResult) NotFound()
        : new FileResult(fileInfo.FullName);
}

And here's one way you can tell IIS to ignore requests with an extension so that the request will make it to the controller:

<!-- web.config -->
<system.webServer>
  <modules runAllManagedModulesForAllRequests="true"/>

Let's say we have a menu like this:

<div class="menu">
  <a href="link1.html">Link 1</a>
  <a href="link2.html">Link 2</a>
  <a href="link3.html">Link 3</a>
  <a href="link4.html">Link 4</a>
</div>

Let our current url be https://demosite.com/link1.html

With the following function we can add the active class to which menu's href is in our url.

let currentURL = window.location.href;

document.querySelectorAll(".menu a").forEach(p => {
  if(currentURL.indexOf(p.getAttribute("href")) !== -1){
    p.classList.add("active");
  }
})

To add a bit of context to M.Ali's Answer you can convert a string to a uniqueidentifier using the following code

   SELECT CONVERT(uniqueidentifier,'DF215E10-8BD4-4401-B2DC-99BB03135F2E')

If that doesn't work check to make sure you have entered a valid GUID

main() is a static method which has two fundamental restrictions:

1. The static method cannot use a non-static data member or directly call non-static method.

2. this() and super() cannot be used in static context.

   class A {  
       int a = 40; //non static
       public static void main(String args[]) {  
           System.out.println(a);  
       }  
   }

This might have been asked before. See Can I add jars to maven 2 build classpath without installing them?

In a nutshell: include your jar as dependency with system scope. This requires specifying the absolute path to the jar.

Installig Eclispe ADT from market place solved this problem for me.

For anyone on a Mac who has Docker Desktop installed. I was able to just click the tray icon and say Restart Docker. Once it restarted was able to delete the containers.

Lets take below object as example

let obj = { property1: 'value 1', property2: 'value 2'};

First fetch all the key in the obj

let keys = Object.keys(obj) //it will return array of keys

and then loop through it

keys.forEach(key => //your way)

just putting all together

Object.keys(obj).forEach(key=>{/*code here*/})

If the string can not be converted to an integer, then

• int.Parse() will throw an exception
• int.TryParse() will return false (but not throw an exception)

Decompyle++ (pycdc) appears to work for a range of python versions: https://github.com/zrax/pycdc

For example:

git clone https://github.com/zrax/pycdc   
cd pycdc
make  
./bin/pycdc Example.pyc > Example.py

Concrete example

mosquitto.org is very active (at the time of this posting). This is a nice smoke test for a MQTT subscriber linux device:

mosquitto_sub -h test.mosquitto.org -t "#" -v

The "#" is a wildcard for topics and returns all messages (topics): the server had a lot of traffic, so it returned a 'firehose' of messages.

If your MQTT device publishes a topic of irisys/V4D-19230005/ to the test MQTT broker , then you could filter the messages:

mosquitto_sub -h test.mosquitto.org -t "irisys/V4D-19230005/#" -v

Options:

• -h the hostname (default MQTT port = 1883)
• -t precedes the topic

Relative Paths

A relative path assumes that the file is on the current server. Using relative paths allows you to construct your site offline and fully test it before uploading it.

For example:

php/webct/itr/index.php

.

Absolute Paths

An absolute path refers to a file on the Internet using its full URL. Absolute paths tell the browser precisely where to go.

For example:

http://www.uvsc.edu/disted/php/webct/itr/index.php

Absolute paths are easier to use and understand. However, it is not good practice on your own website. For one thing, using relative paths allows you to construct your site offline and fully test it before uploading it. If you were to use absolute paths you would have to change your code before uploading it in order to get it to work. This would also be the case if you ever had to move your site or if you changed domain names.

Here's some javascript. Just input x and y values.

var angle = (Math.atan2(x,y) * (180/Math.PI) + 360) % 360;

tl;dr: You want to use curve (with add=TRUE) or lines.

I disagree with par(new=TRUE) because that will double-print tick-marks and axis labels. Eg

The output of plot(sin); par(new=T); plot( function(x) x**2 ).

Look how messed up the vertical axis labels are! Since the ranges are different you would need to set ylim=c(lowest point between the two functions, highest point between the two functions), which is less easy than what I'm about to show you---and way less easy if you want to add not just two curves, but many.

What always confused me about plotting is the difference between curve and lines. (If you can't remember that these are the names of the two important plotting commands, just sing it.)

Here's the big difference between curve and lines.

curve will plot a function, like curve(sin). lines plots points with x and y values, like: lines( x=0:10, y=sin(0:10) ).

And here's a minor difference: curve needs to be called with add=TRUE for what you're trying to do, while lines already assumes you're adding to an existing plot.

Here's the result of calling plot(0:2); curve(sin).

Behind the scenes, check out methods(plot). And check body( plot.function )[[5]]. When you call plot(sin) R figures out that sin is a function (not y values) and uses the plot.function method, which ends up calling curve. So curve is the tool meant to handle functions.

Float the #list and #similar the right and add clear: right; to #similar

Like so:

#map { float:left; width:700px; height:500px; }
#list { float:right; width:200px; background:#eee; list-style:none; padding:0; }
#similar { float:right; width:200px; background:#000; clear:right; } 


<div id="map"></div>        
<ul id="list"></ul>
<div id="similar">this text should be below, not next to ul.</div>

You might need a wrapper(div) around all of them though that's the same width of the left and right element.
