To start redis with a config file all you need to do is specifiy the config file as an argument:

redis-server /root/config/redis.rb

Instead of using and killing PID's I would suggest creating an init script for your service

I would suggest taking a look at the Installing Redis more properly section of http://redis.io/topics/quickstart. It will walk you through setting up an init script with redis so you can just do something like service redis_server start and service redis_server stop to control your server.

I am not sure exactly what distro you are using, that article describes instructions for a Debian based distro. If you are are using a RHEL/Fedora distro let me know, I can provide you with instructions for the last couple of steps, the config file and most of the other steps will be the same.

Not sure this will fix the problem for everyone , But uninstalling java, java SDK and installing the latest version (Version 8) fixed the issue for me ..

This error will also appear if you try to connect to an exposed port from within a Docker container, when nothing is actively serving the port.

On a host where nothing is listening/bound to that port you'd get a No connection could be made because the target machine actively refused it error instead when making a request to a local URL that is not served, eg: localhost:5000. However, if you start a container that binds to the port, but there is no server running inside of it actually serving the port, any requests to that port on localhost will result in:

• [Errno 99] Cannot assign requested address (if called from within the container), or
• [Errno 0] Error (if called from outside of the container).

You can reproduce this error and the behaviour described above as follows:

Start a dummy container (note: this will pull the python image if not found locally):

docker run --name serv1 -p 5000:5000 -dit python

Then for [Errno 0] Error enter a Python console on host, while for [Errno 99] Cannot assign requested address access a Python console on the container by calling:

docker exec -it -u 0 serv1 python

And then in either case call:

import urllib.request
urllib.request.urlopen('https://localhost:5000')

I concluded with treating either of these errors as equivalent to No connection could be made because the target machine actively refused it rather than trying to fix their cause - although please advise if that's a bad idea.

I've spent over a day figuring this one out, given that all resources and answers I could find on the [Errno 99] Cannot assign requested address point in the direction of binding to an occupied port, connecting to an invalid IP, sysctl conflicts, docker network issues, TIME_WAIT being incorrect, and many more things. Therefore I wanted to leave this answer here, despite not being a direct answer to the question at hand, given that it can be a common cause for the error described in this question.

The perfect cls:

cls = lambda: print("\033c\033[3J", end='')
cls()

Or directly:

print("\033c\033[3J", end='')

If you're open to out-of-the-DB solution: You could set up a cron job that runs a script that will itself call the procedure.

This worked for me

PHP File

<?php
$target_path  = "./Upload/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']).    " has been uploaded";
} else {
    echo "There was an error uploading the file, please try again!";
}

?>

A general purpose way is to coerce the collation to DATABASE_DEFAULT. This removes hardcoding the collation name which could change.

It's also useful for temp table and table variables, and where you may not know the server collation (eg you are a vendor placing your system on the customer's server)

select
    sone_field collate DATABASE_DEFAULT
from
    table_1
    inner join
    table_2 on table_1.field collate DATABASE_DEFAULT = table_2.field
where whatever

There is no rule. I find CTEs more readable, and use them unless they exhibit some performance problem, in which case I investigate the actual problem rather than guess that the CTE is the problem and try to re-write it using a different approach. There is usually more to the issue than the way I chose to declaratively state my intentions with the query.

There are certainly cases when you can unravel CTEs or remove subqueries and replace them with a #temp table and reduce duration. This can be due to various things, such as stale stats, the inability to even get accurate stats (e.g. joining to a table-valued function), parallelism, or even the inability to generate an optimal plan because of the complexity of the query (in which case breaking it up may give the optimizer a fighting chance). But there are also cases where the I/O involved with creating a #temp table can outweigh the other performance aspects that may make a particular plan shape using a CTE less attractive.

Quite honestly, there are way too many variables to provide a "correct" answer to your question. There is no predictable way to know when a query may tip in favor of one approach or another - just know that, in theory, the same semantics for a CTE or a single subquery should execute the exact same. I think your question would be more valuable if you present some cases where this is not true - it may be that you have discovered a limitation in the optimizer (or discovered a known one), or it may be that your queries are not semantically equivalent or that one contains an element that thwarts optimization.

So I would suggest writing the query in a way that seems most natural to you, and only deviate when you discover an actual performance problem the optimizer is having. Personally I rank them CTE, then subquery, with #temp table being a last resort.

White Box Testing equals Software Unit Test. The developer or a development level tester (e.g. another developer) ensures that the code he has written is working properly according to the detailed level requirements before integrating it in the system.

Black Box Testing equals Integration Testing. The tester ensures that the system works according to the requirements on a functional level.

Both test approaches are equally important in my opinion.

A thorough unit test will catch defects in the development stage and not after the software has been integrated into the system. A system level black box test will ensure all software modules behave correctly when integrated together. A unit test in the development stage would not catch these defects since modules are usually developed independent from each other.

It is not possible to redirect a POST somewhere else. When you have POSTED the request, the browser will get a response from the server and then the POST is done. Everything after that is a new request. When you specify a location header in there the browser will always use the GET method to fetch the next page.

You could use some Ajax to submit the form in background. That way your form values stay intact. If the server accepts, you can still redirect to some other page. If the server does not accept, then you can display an error message, let the user correct the input and send it again.

Are you sure you need to use sed? How about:

tr -d "\""

Here's a full working example.
If it's only extracting email addresses you could just do something like:
1) Suppose XML file spam.xml is like

<spam>
<victims>
  <victim>
    <name>The Pope</name>
    <email>[email protected]</email>
    <is_satan>0</is_satan>
  </victim>
  <victim>
    <name>George Bush</name>
    <email>[email protected]</email>
    <is_satan>1</is_satan>
  </victim>
  <victim>
    <name>George Bush Jr</name>
    <email>[email protected]</email>
    <is_satan>0</is_satan>
  </victim>
</victims>
</spam>

2) You can get the emails and process them with this short bash code:

#!/bin/bash
emails=($(grep -oP '(?<=email>)[^<]+' "/my_path/spam.xml"))

for i in ${!emails[*]}
do
  echo "$i" "${emails[$i]}"
  # instead of echo use the values to send emails, etc
done

Result of this example is:

0 [email protected]
1 [email protected]
2 [email protected]

Important note:
Don't use this for serious matters. This is OK for playing around, getting quick results, learning grep, etc. but you should definitely look for, learn and use an XML parser for production (see Micha's comment below).

To clone a generic interface like java.util.List you will just need to cast it. here you are an example:

List list = new ArrayList();
List list2 = ((List) ( (ArrayList) list).clone());

It is a bit tricky, but it works, if you are limited to return a List interface, so anyone after you can implement your list whenever he wants.

I know this answer is close to the final answer, but my answer answers how to do all of that while you are working with List -the generic parent- not ArrayList

Here's another way to do it in VBA.

Function ConvertToArray(ByVal value As String)
    value = StrConv(value, vbUnicode)
    ConvertToArray = Split(Left(value, Len(value) - 1), vbNullChar)
End Function
Sub example()
    Dim originalString As String
    originalString = "hi there"
    Dim myArray() As String
    myArray = ConvertToArray(originalString)
End Sub

Right, click on the project. Go to Maven -> Update Project.

The dependencies will automatically be installed.

Instead of using this as the accepted answer suggests, use $parent instead. So in your partial1.htmlyou'll have:

<form ng-submit="$parent.addLine()">
    <input type="text" ng-model="$parent.lineText" size="30" placeholder="Type your message here">
</form>

Check out fontsquirrel. They have a web font generator, which will also spit out a suitable stylesheet for your font (look for "@font-face kit"). This stylesheet can be included in your own, or you can use it as a template.

You can use the built-in http module to do an http.request().

However if you want to simplify the API you can use a module such as superagent

As of Notepad++ v7.6, use Plugin Admin to install JSTool per this answer

INSTALL

Download it from http://sourceforge.net/projects/jsminnpp/ and copy JSMinNpp.dll to plugin directory of Notepad++. Or you can just install "JSTool" from Plugin Manager in Notepad++.

New Notepad++ install and where did PluginManager go? See How to view Plugin Manager in Notepad++

If you do not want to use angular-ui-router, but would like to have your controllers lazy loaded via RequireJS, there are couple of problems with event $routeChangeStart when using your controllers as RequireJS modules (lazy loaded).

You cannot be sure the controller will be loaded before $routeChangeStart gets triggered -- in fact it wont be loaded. That means you cannot access properties of next route like locals or $$route because they are not yet setup.
Example:

app.config(["$routeProvider", function($routeProvider) {
    $routeProvider.when("/foo", {
        controller: "Foo",
        resolve: {
            controller: ["$q", function($q) {
                var deferred = $q.defer();
                require(["path/to/controller/Foo"], function(Foo) {
                    // now controller is loaded
                    deferred.resolve();
                });
                return deferred.promise;
            }]
        }
    });
}]);

app.run(["$rootScope", function($rootScope) {
    $rootScope.$on("$routeChangeStart", function(event, next, current) {
        console.log(next.$$route, next.locals); // undefined, undefined
    });
}]);

This means you cannot check access rights in there.

Solution:

As loading of controller is done via resolve, you can do the same with your access control check:

app.config(["$routeProvider", function($routeProvider) {
    $routeProvider.when("/foo", {
        controller: "Foo",
        resolve: {
            controller: ["$q", function($q) {
                var deferred = $q.defer();
                require(["path/to/controller/Foo"], function(Foo) {
                    // now controller is loaded
                    deferred.resolve();
                });
                return deferred.promise;
            }],
            access: ["$q", function($q) {
                var deferred = $q.defer();
                if (/* some logic to determine access is granted */) {
                    deferred.resolve();
                } else {
                    deferred.reject("You have no access rights to go there");
                }
                return deferred.promise;
            }],
        }
    });
}]);

app.run(["$rootScope", function($rootScope) {
    $rootScope.$on("$routeChangeError", function(event, next, current, error) {
        console.log("Error: " + error); // "Error: You have no access rights to go there"
    });
}]);

Note here that instead of using event $routeChangeStart I'm using $routeChangeError

box-shadow: -15px 0px 17px -7px rgba(0,0,0,0.75);

The first px value is the "Horizontal Length" set to -15px to position the shadow towards the left, the next px value is set to 0 so the shadow top and bottom is centred to minimise the top and bottom shadow.

The third value(17px) is known as the blur radius. The higher the number, the more blurred the shadow will be. And then last px value -7px is The spread radius, a positive value increases the size of the shadow, a negative value decreases the size of the shadow, at -7px it keeps the shadow from appearing above and below the item.

Or you can just use commands.getstatusoutput:

   commands.getstatusoutput("ssh machine 1 'your script'")

I used it extensively and it works great.

In Python 2.6+, use subprocess.check_output.

The stream editor does modify multiple files “inplace” when invoked with the -i switch, which takes a backup file ending as argument. So

sed -i.bak 's/foo/bar/g' *

replaces foo with bar in all files in this folder, but does not descend into subfolders. This will however generate a new .bak file for every file in your directory. To do this recursively for all files in this directory and all its subdirectories, you need a helper, like find, to traverse the directory tree.

find ./ -print0 | xargs -0 sed -i.bak 's/foo/bar/g' *

find allows you further restrictions on what files to modify, by specifying further arguments like find ./ -name '*.php' -or -name '*.html' -print0, if necessary.

Note: GNU sed does not require a file ending, sed -i 's/foo/bar/g' * will work, as well; FreeBSD sed demands an extension, but allows a space in between, so sed -i .bak s/foo/bar/g * works.

You just need to put -y with the install command.

For example: yum install <package_to_install> -y

To call a specific exception such as FileNotFoundException use this format

if (-not (Test-Path $file)) 
{
    throw [System.IO.FileNotFoundException] "$file not found."
}

To throw a general exception use the throw command followed by a string.

throw "Error trying to do a task"

When used inside a catch, you can provide additional information about what triggered the error

You can do that in this way:

ORDER BY `products`.`product_category_id` DESC ,`naam` ASC

Have a look at ORDER BY Optimization

you don't need to specify a "SimpleDateFormat", it's simple: You must do specify the constant "DatatypeConstants.FIELD_UNDEFINED" where you don't want to show

GregorianCalendar cal = new GregorianCalendar();
cal.setTime(new Date());
XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance().newXMLGregorianCalendarDate(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH)+1, cal.get(Calendar.DAY_OF_MONTH), DatatypeConstants.FIELD_UNDEFINED);

Two options for runtime type checking with generics:

Option 1 - Corrupt your constructor

Let's assume you are overriding indexOf(...), and you want to check the type just for performance, to save yourself iterating the entire collection.

Make a filthy constructor like this:

public MyCollection<T>(Class<T> t) {

    this.t = t;
}

Then you can use isAssignableFrom to check the type.

public int indexOf(Object o) {

    if (
        o != null &&

        !t.isAssignableFrom(o.getClass())

    ) return -1;

//...

Each time you instantiate your object you would have to repeat yourself:

new MyCollection<Apples>(Apples.class);

You might decide it isn't worth it. In the implementation of ArrayList.indexOf(...), they do not check that the type matches.

Option 2 - Let it fail

If you need to use an abstract method that requires your unknown type, then all you really want is for the compiler to stop crying about instanceof. If you have a method like this:

protected abstract void abstractMethod(T element);

You can use it like this:

public int indexOf(Object o) {

    try {

        abstractMethod((T) o);

    } catch (ClassCastException e) {

//...

You are casting the object to T (your generic type), just to fool the compiler. Your cast does nothing at runtime, but you will still get a ClassCastException when you try to pass the wrong type of object into your abstract method.

NOTE 1: If you are doing additional unchecked casts in your abstract method, your ClassCastExceptions will get caught here. That could be good or bad, so think it through.

NOTE 2: You get a free null check when you use instanceof. Since you can't use it, you may need to check for null with your bare hands.

If you don't want to hardcode the CSS into a CSS block/file, you can use jQuery to dynamically add CSS to HTML Elements, ID's, and Classes.

$(document).ready(function() {
  //Build your CSS.
  var body_tag_css = {
    "background-color": "#ddd",
    "font-weight": "",
    "color": "#000"
  }
  //Apply your CSS to the body tag.  You can enter any tag here, as
  //well as ID's and Classes.
  $("body").css(body_tag_css);
});

The hidden input element trick still appears to work (Chrome 43) to prevent autofill, but one thing to keep in mind is that Chrome will attempt to autofill based on the placeholder tag. You need to match the hidden input element's placeholder to that of the input you're trying to disable.

In my case, I had a field with a placeholder text of 'City or Zip' which I was using with Google Place Autocomplete. It appeared that it was attempting to autofill as if it were part of an address form. The trick didn't work until I put the same placeholder on the hidden element as on the real input:

<input style="display:none;" type="text" placeholder="City or Zip" />
<input autocomplete="off" type="text" placeholder="City or Zip" />

SELECT field1, field2, 'Test' AS field3 FROM Test; // replace with simple quote '

>>> import os
>>> if os.path.exists("myfile.dat"):
...     f = file("myfile.dat", "r+")
... else:
...     f = file("myfile.dat", "w")

r+ means read/write

Use Resizemode with 'cover' or 'contain' and set the height and with of the Image.

Talking about efficiency:

document.getElementById( 'elemtId' ).style.display = 'none';

What jQuery does with its .show() and .hide() methods is, that it remembers the last state of an element. That can come in handy sometimes, but since you asked about efficiency that doesn't matter here.

There is a little hack with php. And it works not only with Google, but with any website you don't control and can't add Access-Control-Allow-Origin *

We need to create PHP-file (ex. getContentFromUrl.php) on our webserver and make a little trick.

PHP

<?php

$ext_url = $_POST['ext_url'];

echo file_get_contents($ext_url);

?>

JS

$.ajax({
    method: 'POST',
    url: 'getContentFromUrl.php', // link to your PHP file
    data: {
        // url where our server will send request which can't be done by AJAX
        'ext_url': 'https://stackoverflow.com/questions/6114436/access-control-allow-origin-error-sending-a-jquery-post-to-google-apis'
    },
    success: function(data) {
        // we can find any data on external url, cause we've got all page
        var $h1 = $(data).find('h1').html();

        $('h1').val($h1);
    },
    error:function() {
        console.log('Error');
    }
});

How it works:

1. Your browser with the help of JS will send request to your server
2. Your server will send request to any other server and get reply from another server (any website)
3. Your server will send this reply to your JS

And we can make events onClick, put this event on some button. Hope this will help!

Note: You CANNOT UNDO this.

Try git checkout -f this will discard any local changes which are not committed in ALL branches and master.

Use the following extensions and just pass the action like:

_frmx.PerformSafely(() => _frmx.Show());
_frmx.PerformSafely(() => _frmx.Location = new Point(x,y));

Extension class:

public static class CrossThreadExtensions
{
    public static void PerformSafely(this Control target, Action action)
    {
        if (target.InvokeRequired)
        {
            target.Invoke(action);
        }
        else
        {
            action();
        }
    }

    public static void PerformSafely<T1>(this Control target, Action<T1> action,T1 parameter)
    {
        if (target.InvokeRequired)
        {
            target.Invoke(action, parameter);
        }
        else
        {
            action(parameter);
        }
    }

    public static void PerformSafely<T1,T2>(this Control target, Action<T1,T2> action, T1 p1,T2 p2)
    {
        if (target.InvokeRequired)
        {
            target.Invoke(action, p1,p2);
        }
        else
        {
            action(p1,p2);
        }
    }
}

I think this question is a bit misleading since, toString() in Java isn't just a way to cast something to a String. That is what casting via (string) or String.valueOf() does, and it works as well in PHP.

// Java
String myText = (string) myVar;

// PHP
$myText = (string) $myVar;

Note that this can be problematic as Java is type-safe (see here for more details).

But as I said, this is casting and therefore not the equivalent of Java's toString().

toString in Java doesn't just cast an object to a String. It instead will give you the String representation. And that's what __toString() in PHP does.

// Java
class SomeClass{
    public String toString(){
        return "some string representation";
    }
}

// PHP
class SomeClass{
    public function __toString()
    {
        return "some string representation";
    }
}

And from the other side:

// Java
new SomeClass().toString(); // "Some string representation"

// PHP
strval(new SomeClass); // "Some string representation"

What do I mean by "giving the String representation"? Imagine a class for a library with millions of books.

• Casting that class to a String would (by default) convert the data, here all books, into a string so the String would be very long and most of the time not very useful either.
• To String instead will give you the String representation, i.e., only the name of the library. This is shorter and therefore gives you less, but more important information.

These are both valid approaches but with very different goals, neither is a perfect solution for every case and you have to chose wisely which fits better for your needs.

Sure, there are even more options:

$no = 421337  // A number in PHP
$str = "$no"; // In PHP, stuff inside "" is calculated and variables are replaced
$str = print_r($no, true); // Same as String.format();
$str = settype($no, 'string'); // Sets $no to the String Type
$str = strval($no); // Get the string value of $no
$str = $no . ''; // As you said concatenate an empty string works too

All of these methods will return a String, some of them using __toString internally and some others will fail on Objects. Take a look at the PHP documentation for more details.

If you don't call the favicon, favicon.ico, you can use that tag to specify the actual path (incase you have it in an images/ directory). The browser/webpage looks for favicon.ico in the root directory by default.

For rows, try this, where Name is the joint index column (can be a list for multiple common columns, or specify left_on and right_on):

m = df1.merge(df2, on='Name', how='outer', suffixes=['', '_'], indicator=True)

The indicator=True setting is useful as it adds a column called _merge, with all changes between df1 and df2, categorized into 3 possible kinds: "left_only", "right_only" or "both".

For columns, try this:

set(df1.columns).symmetric_difference(df2.columns)

What worked for me was to activate the option for less secure apps (I am using VB.NET)

Public Shared Sub enviaDB(ByRef body As String, ByRef file_location As String)
        Dim mail As New MailMessage()
        Dim SmtpServer As New SmtpClient("smtp.gmail.com")
        mail.From = New MailAddress("[email protected]")
        mail.[To].Add("[email protected]")
        mail.Subject = "subject"
        mail.Body = body
        Dim attachment As System.Net.Mail.Attachment
        attachment = New System.Net.Mail.Attachment(file_location)
        mail.Attachments.Add(attachment)
        SmtpServer.Port = 587
        SmtpServer.Credentials = New System.Net.NetworkCredential("user", "password")
        SmtpServer.EnableSsl = True
        SmtpServer.Send(mail)
    End Sub

So log in to your account and then go to google.com/settings/security/lesssecureapps

As elements are yet ordered, you don't have to build a map, there's a fast solution :

var newarr = [arr[0]];
for (var i=1; i<arr.length; i++) {
   if (arr[i]!=arr[i-1]) newarr.push(arr[i]);
}

If your array weren't sorted, you would use a map :

var newarr = (function(arr){
  var m = {}, newarr = []
  for (var i=0; i<arr.length; i++) {
    var v = arr[i];
    if (!m[v]) {
      newarr.push(v);
      m[v]=true;
    }
  }
  return newarr;
})(arr);

Note that this is, by far, much faster than the accepted answer.

Note that both pcolor and "surf + view(2)" do not show the last row and the last column of your 2D data.

On the other hand, using imagesc, you have to be careful with the axes. The surf and the imagesc examples in gevang's answer only (almost -- apart from the last row and column) correspond to each other because the 2D sinc function is symmetric.

To illustrate these 2 points, I produced the figure below with the following code:

[x, y] = meshgrid(1:10,1:5);
z      = x.^3 + y.^3;

subplot(3,1,1)
imagesc(flipud(z)), axis equal tight, colorbar
set(gca, 'YTick', 1:5, 'YTickLabel', 5:-1:1);
title('imagesc')

subplot(3,1,2)
surf(x,y,z,'EdgeColor','None'), view(2), axis equal tight, colorbar
title('surf with view(2)')

subplot(3,1,3)
imagesc(flipud(z)), axis equal tight, colorbar
axis([0.5 9.5 1.5 5.5])
set(gca, 'YTick', 1:5, 'YTickLabel', 5:-1:1);
title('imagesc cropped')

colormap jet

As you can see the 10th row and 5th column are missing in the surf plot. (You can also see this in images in the other answers.)

Note how you can use the "set(gca, 'YTick'..." (and Xtick) command to set the x and y tick labels properly if x and y are not 1:1:N.

Also note that imagesc only makes sense if your z data correspond to xs and ys are (each) equally spaced. If not you can use surf (and possibly duplicate the last column and row and one more "(end,end)" value -- although that's a kind of a dirty approach).

The following signature will do:

List<Email> findByEmailIdInAndPincodeIn(List<String> emails, List<String> pinCodes);

Spring Data JPA supports a large number of keywords to build a query. IN and AND are among them.

You need to explicitly enable the home action if running on ICS. From the docs:

Note: If you're using the icon to navigate to the home activity, beware that beginning with Android 4.0 (API level 14), you must explicitly enable the icon as an action item by calling setHomeButtonEnabled(true) (in previous versions, the icon was enabled as an action item by default).

onChange will not call handleChange on mobile when using defaultChecked. As an alternative you can can use onClick and onTouchEnd.

<input onClick={this.handleChange} onTouchEnd={this.handleChange} type="checkbox" defaultChecked={!!this.state.complete} />;

I think the problem is that the browser could not load the jQueryUI image sprite that contains the X icon. Please use Fiddler, Firebug, or some other that can give you access to the HTTP requests the browser makes to the server and verify the image sprite is loaded successfully.

Using ...
search = (^.*import )(.*)(\(.*\):)
replace = $1$2

...replaces ...

from checks import checklist(_list):

...with...

from checks import checklist

Blocks in regex are delineated by parenthesis (which are not preceded by a "\")

(^.*import ) finds "from checks import " and loads it to $1 (eclipse starts counting at 1)

(.*) find the next "everything" until the next encountered "(" and loads it to $2. $2 stops at the "(" because of the next part (see next line below)

(\(.*\):) says "at the first encountered "(" after starting block $2...stop block $2 and start $3. $3 gets loaded with the "('any text'):" or, in the example, the "(_list):"

Then in the replace, just put the $1$2 to replace all three blocks with just the first two.

Just use NVM(Node Version Manager) - https://github.com/creationix/nvm

It has become the standard for managing Node.js.

When you need a new version:

nvm install NEW_VER
nvm use XXX

If something goes wrong you can always go back with

nvm use OLD_VER

This code make clean dataframe:

df = pd.DataFrame({'a':[1,2], 'b':[3,4]})
#clean
df = pd.DataFrame()

I'd use popen() (++waqas).

But sometimes you need reading and writing...

It seems like nobody does things the hard way any more.

Meteor's strength is in it's real-time updates feature which works well for some of the social applications you see nowadays where you see everyone's updates for what you're working on. These updates center around replicating subsets of a MongoDB collection underneath the covers as local mini-mongo (their client side MongoDB subset) database updates on your web browser (which causes multiple render events to be fired on your templates). The latter part about multiple render updates is also the weakness. If you want your UI to control when the UI refreshes (e.g., classic jQuery AJAX pages where you load up the HTML and you control all the AJAX calls and UI updates), you'll be fighting this mechanism.

Meteor uses a nice stack of Node.js plugins (Handlebars.js, Spark.js, Bootstrap css, etc. but using it's own packaging mechanism instead of npm) underneath along w/ MongoDB for the storage layer that you don't have to think about. But sometimes you end up fighting it as well...e.g., if you want to customize the Bootstrap theme, it messes up the loading sequence of Bootstrap's responsive.css file so it no longer is responsive (but this will probably fix itself when Bootstrap 3.0 is released soon).

So like all "full stack frameworks", things work great as long as your app fits what's intended. Once you go beyond that scope and push the edge boundaries, you might end up fighting the framework...

The simplest solution is to use ThresholdFilter on the appenders:

    <appender name="..." class="...">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>INFO</level>
        </filter>

Full example:

<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>INFO</level>
        </filter>
        <encoder>
            <pattern>%d %-5level: %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="STDERR" class="ch.qos.logback.core.ConsoleAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
        <target>System.err</target>
        <encoder>
            <pattern>%d %-5level: %msg%n</pattern>
        </encoder>
    </appender>

    <root>
        <appender-ref ref="STDOUT" />
        <appender-ref ref="STDERR" />
    </root>
</configuration>

Update: As Mike pointed out in the comment, messages with ERROR level are printed here both to STDOUT and STDERR. Not sure what was the OP's intent, though. You can try Mike's answer if this is not what you wanted.

In the manifest file Change:

    android:theme="@style/AppTheme" >
    android:theme="@style/Theme.AppCompat.NoActionBar"

After several attempts and going deep in Tomcat's source code I found out that the simple property useNaming="false" did the trick!! Now Tomcat resolves names java:/liferay instead of java:comp/env/liferay

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

Make sure you declare the variable on "root" level, outside any code blocks.

You could also remove the var altogether, although that is not recommended and will throw a "strict" warning.

According to the documentation at MDC, you can set global variables using window.variablename.

The difference come in relational algebra where project affects columns and select affect rows. However in query syntax, select is the word. There is no such query as project. Assuming there is a table named users with hundreds of thousands of records (rows) and the table has 6 fields (userID, Fname,Lname,age,pword,salary). Lets say we want to restrict access to sensitive data (userID,pword and salary) and also restrict amount of data to be accessed. In mysql maria DB we create a view as follows ( Create view user1 as select Fname,Lname, age from users limit 100;) from our view we issue (select Fname from users1;) . This query is both a select and a project

try running tor service, add the following function to your code.

def connect_tor(port):

socks.set_default_proxy(socks.PROXY_TYPE_SOCKS5, '127.0.0.1', port, True)
socket.socket = socks.socksocket

def main():

connect_tor()
driver = webdriver.Firefox()

Set the Current Cell like:

DataGridView1.CurrentCell = DataGridView1.Rows[rowindex].Cells[columnindex]

or

DataGridView1.CurrentCell = DataGridView1.Item("ColumnName", 5)

and you can directly focus with Editing by:

dataGridView1.BeginEdit(true)

This function opens a URL without requiring additional user interaction.

/**
 * Open a URL in a new tab.
 */
function openUrl( url ){
  var html = HtmlService.createHtmlOutput('<html><script>'
  +'window.close = function(){window.setTimeout(function(){google.script.host.close()},9)};'
  +'var a = document.createElement("a"); a.href="'+url+'"; a.target="_blank";'
  +'if(document.createEvent){'
  +'  var event=document.createEvent("MouseEvents");'
  +'  if(navigator.userAgent.toLowerCase().indexOf("firefox")>-1){window.document.body.append(a)}'                          
  +'  event.initEvent("click",true,true); a.dispatchEvent(event);'
  +'}else{ a.click() }'
  +'close();'
  +'</script>'
  // Offer URL as clickable link in case above code fails.
  +'<body style="word-break:break-word;font-family:sans-serif;">Failed to open automatically. <a href="'+url+'" target="_blank" onclick="window.close()">Click here to proceed</a>.</body>'
  +'<script>google.script.host.setHeight(40);google.script.host.setWidth(410)</script>'
  +'</html>')
  .setWidth( 90 ).setHeight( 1 );
  SpreadsheetApp.getUi().showModalDialog( html, "Opening ..." );
}

This method works by creating a temporary dialog box, so it will not work in contexts where the UI service is not accessible, such as the script editor or a custom G Sheets formula.

Use of the argmin method for numpy arrays.

import numpy as np
np.argmin(myList)

However, it is not the fastest method: it is 3 times slower than OP's answer on my computer. It may be the most concise one though.

String.matches returns whether the whole string matches the regex, not just any substring.

You could do this:

echo "<script>alert('Successfully Updated'); window.location = './edit.php';</script>";

On python 3.5+ there is an easier way to achieve a shallow copy by using the ** unpackaging operator. Defined by Pep 448.

>>>dict1 = {"key1": "value1", "key2": "value2"}
>>>dict2 = {**dict1}
>>>print(dict2)
{'key1': 'value1', 'key2': 'value2'}
>>>dict2["key2"] = "WHY?!"
>>>print(dict1)
{'key1': 'value1', 'key2': 'value2'}
>>>print(dict2)
{'key1': 'value1', 'key2': 'WHY?!'}

** unpackages the dictionary into a new dictionary that is then assigned to dict2.

We can also confirm that each dictionary has a distinct id.

>>>id(dict1)
 178192816

>>>id(dict2)
 178192600

If a deep copy is needed then copy.deepcopy() is still the way to go.

Here is how I did it by trial and error.

ScrollView - (the outer wrapper).

    LinearLayout (child-1).

        LinearLayout (child-1a).

        LinearLayout (child-1b).

Since ScrollView can have only one child, that child is a linear layout. Then all the other layout types occur in the first linear layout. I haven't tried to include a relative layout yet, but they drive me nuts so I will wait until my sanity returns.

You need to add an alias for the count to your query and then use the addScalar() method as the default for list() method in Hibernate seams to be BigInteger for numeric SQL types. Here is an example:

List<Long> sqlResult = session.createSQLQuery("SELECT column AS num FROM table")
    .addScalar("num", StandardBasicTypes.LONG).list();

You can also create a new document from MongoDB compass or using command and set the specific _id value that you want.

Use this code:

internal void SomeFunction() {
    Dictionary<string, string> formField = new Dictionary<string, string>();
    
    formField.Add("Name", "Henry");
    formField.Add("Age", "21");
    
    string body = GetBodyStringFromDictionary(formField);
    // output : Name=Henry&Age=21
}

internal string GetBodyStringFromDictionary(Dictionary<string, string> formField)
{
    string body = string.Empty;
    foreach (var pair in formField)
    {
        body += $"{pair.Key}={pair.Value}&";   
    }

    // delete last "&"
    body = body.Substring(0, body.Length - 1);

    return body;
}

Unfortunately you cannot.
I tried using the CSS max function in padding to attempt this functionality, but I got a parse error in my css. Below is what I tried:

padding: 5px max(50vw - 350px, 10vw);

I then tried to separate the operations into variables, and that didn't work either

  --padding: calc(50vw - 350px); 
  --max-padding: max(1vw, var(--padding));
  padding: 5px var(--max-padding);

What eventually worked was just nesting what I wanted padded in a div with class "centered" and using max width and width like so

 .centered {
   width: 98vw;
   max-width: 700px;
   height: 100%;
   margin: 0 auto;
}

Unfortunately, this appears to be the best way to mimic a "max-padding" and "min-padding". I imagine the technique would be similar for "min-margin" and "max-margin". Hopefully this gets added at some point!

If your text contains only one individual:

import re

# creation
with open('pers.txt','wb') as g:
    g.write('Dan \n Warrior \n 500 \r\n 1 \r 0 ')

with open('pers.txt','rb') as h:
    print 'exact content of pers.txt before treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
    print '\nrU-display of pers.txt before treatment:\n',h.read()


# treatment
def roplo(file_name,what):
    patR = re.compile('^([^\r\n]+[\r\n]+)[^\r\n]+')
    with open(file_name,'rb+') as f:
        ch = f.read()
        f.seek(0)
        f.write(patR.sub('\\1'+what,ch))
roplo('pers.txt','Mage')

    print '\nexact content of pers.txt after treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
    print '\nrU-display of pers.txt after treatment:\n',h.read()

If your text contains several individuals:

import re

# creation
with open('pers.txt','wb') as g:
    g.write('Dan \n Warrior \n 500 \r\n 1 \r 0 \n Jim  \n  dragonfly\r300\r2\n10\r\nSomo\ncosmonaut\n490\r\n3\r65')

with open('pers.txt','rb') as h:
    print 'exact content of pers.txt before treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:

# treatment
def ripli(file_name,who,what):
    with open(file_name,'rb+') as f:
        ch = f.read()
        x,y = re.search('^\s*'+who+'\s*[\r\n]+([^\r\n]+)',ch,re.MULTILINE).span(1)
        f.seek(x)
        f.write(what+ch[y:])

    print 'exact content of pers.txt after treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
    print '\nrU-display of pers.txt after treatment:\n',h.read()

If the “job“ of an individual was of a constant length in the texte, you could change only the portion of texte corresponding to the “job“ the desired individual: that’s the same idea as senderle’s one.

But according to me, better would be to put the characteristics of individuals in a dictionnary recorded in file with cPickle:

from cPickle import dump, load

with open('cards','wb') as f:
    dump({'Dan':['Warrior',500,1,0],'Jim':['dragonfly',300,2,10],'Somo':['cosmonaut',490,3,65]},f)

with open('cards','rb') as g:
    id_cards = load(g)
print 'id_cards before change==',id_cards

id_cards['Jim'][0] = 'Wizard'

with open('cards','w') as h:
    dump(id_cards,h)

with open('cards') as e:
    id_cards = load(e)
print '\nid_cards after change==',id_cards

The Angular microsyntax lets you configure a directive in a compact, friendly string. The microsyntax parser translates that string into attributes on the <ng-template>. The let keyword declares a template input variable that you reference within the template.

We were trying to avoid using the IE specific

$window[0].document.body.clientHeight 

And found that the following jQuery will not consistently yield the same value but eventually does at some point in our page load scenario which worked for us and maintained cross-browser support:

$(document).height()

virtualenv --python=/usr/local/bin/python3 <VIRTUAL ENV NAME> this will add python3 path for your virtual enviroment.

And if everything else fails from these great choice of answers, you can always use "find" like this. Or you may need to use sudo

If you are root, just type $$> find / -name 'postgres'

If you are a user, you will need sudo priv's to run it through all the directories

I run it this way, from the / base to find the whole path that the element is found in. This will return any files or directories with the "postgres" in it.

You could do the same thing looking for the pg_hba.conf or postgresql.conf files also.

As said by @Nancom

<mvc:resources location="/resources/" mapping="/resource/**"/>

So for clarity lets our image is in

resources/images/logo.png"

The location attribute of the mvc:resources tag defines the base directory location of static resources that you want to serve. It can be images path that are available under the src/main/webapp/resources/images/ directory; you may wonder why we have given only /resources/ as the location value instead of src/main/webapp/resources/images/. This is because we consider the resources directory as the base directory for all resources, we can have multiple sub-directories under resources directory to put our images and other static resource files.

The second attribute, mapping, just indicates the request path that needs to be mapped to this resources directory. In our case, we have assigned /resource/** as the mapping value. So, if any web request starts with the /resource request path, then it will be mapped to the resources directory, and the /** symbol indicates the recursive look for any resource files underneath the base resources directory.

So for url like http://localhost:8080/webstore/resource/images/logo.png. So, while serving this web request, Spring MVC will consider /resource/images/logo.png as the request path. So, it will try to map /resource to the base directory specified by the location attribute, resources. From this directory, it will try to look for the remaining path of the URL, which is /images/logo.png. Since we have the images directory under the resources directory, Spring can easily locate the image file from the images directory.

So

 <mvc:resources location="/resources/" mapping="/resource/**"/>

gives us for given [requests] -> [resource mapping]:

http://localhost:8080/webstore/resource/images/logo.png -> searches in resources/images/logo.png

http://localhost:8080/webstore/resource/images/small/picture.png -> searches in resources/images/small/picture.png

http://localhost:8080/webstore/resource/css/main.css -> searches in resources/css/main.css

http://localhost:8080/webstore/resource/pdf/index.pdf -> searches in resources/pdf/index.pdf

I fixed the issue without changing the python path as that did not seem like the right solution for me. The following solution worked for me, hopefully it works for you as well :))

1. Open cmd in windows / shell in Linux/Mac.

2. Activate your virtualenv (using source activate / activate.bat / activate.ps1 if using power shell)

   C:\Users\<myUserName>\Videos\myFolder>django-project\Scripts\activate.bat (django-project) C:\Users\<myUserName>\Videos\myFolder>

3. Navigate to your project directory and open vscode there.

   (django-project) C:\Users\prash\Videos\myFolder\projects>code .

4. in VS Code, goto File --> Preferences --> Settings (dont worry you dont need to open the json file)

5. In the setting search bar search for virtual / venv and hit enter. You should find the below in the search bar:

Python: Venv Folders Folders in your home directory to look into for virtual environments (supports pyenv, direnv and virtualenvwrapper by default).

6. Add item, and then enter the path of the scripts of your virtuanenv which has the activate file in it. For example in my system, it is:

   C:\Users\<myUserName>\Videos\myFolder\django-project\Scripts\

7. Save it and restart VS Code.

8. To restart, open cmd again, navigate to your project path and open vs code. (Note that your venv should be activated in cmd before you open vs code from cmd)

Command to open vs code from cmd:

code .

int len=sizeof(array)/sizeof(int);

Should work.

For MAC user, add this line into your Default Settings

File path is: /Users/USER_NAME/Library/Application Support/Code/User/settings.json

"tslint.autoFixOnSave": true

Sample of the file would be:

{
    "window.zoomLevel": 0,
    "workbench.iconTheme": "vscode-icons",
    "typescript.check.tscVersion": false,
    "vsicons.projectDetection.disableDetect": true,
    "typescript.updateImportsOnFileMove.enabled": "always",
    "eslint.autoFixOnSave": true,
    "tslint.autoFixOnSave": true
}

Edit September 2016: Although it's nice to still get an occasional up-vote for this, because the world has moved on, I'd now go with the answer that uses transform (and which has a ton of upvotes). I wouldn't do it this way any more.

Another way not to have to calculate a margin or need a sub-container:

#menu {
    position: fixed;   /* Take it out of the flow of the document */
    left: 0;           /* Left edge at left for now */
    right: 0;          /* Right edge at right for now, so full width */ 
    top: 30px;         /* Move it down from top of window */
    width: 500px;      /* Give it the desired width */ 
    margin: auto;      /* Center it */
    max-width: 100%;   /* Make it fit window if under 500px */ 
    z-index: 10000;    /* Whatever needed to force to front (1 might do) */
}

IIF is a non-standard T-SQL function. It was added to SQL SERVER 2012, so that Access could migrate to SQL Server without refactoring the IIF's to CASE before hand. Once the Access db is fully migrated into SQL Server, you can refactor.

Quick fix:

1. Open /etc/paths
2. Change the order of the lines (highest priority on top)

In my case /etc/paths looks like:

/usr/local/bin
/usr/local/sbin
/usr/bin
/bin
/usr/sbin
/sbin

If you want to know more about paths in OSX I found this article quite useful:

I found this question while trying to figure out why I could not connect to redis after starting it via brew services start redis.

tl;dr

Depending on how fresh your machine or install is you're likely missing a config file or a directory for the redis defaults.

1. You need a config file at /usr/local/etc/redis.conf. Without this file redis-server will not start. You can copy over the default config file and modify it from there with

   cp /usr/local/etc/redis.conf.default /usr/local/etc/redis.conf
   

2. You need /usr/local/var/db/redis/ to exist. You can do this easily with

   mkdir -p /usr/local/var/db/redis
   

Finally just restart redis with brew services restart redis.

How do you find this out!?

I wasted a lot of time trying to figure out if redis wasn't using the defaults through homebrew and what port it was on. Services was misleading because even though redis-server had not actually started, brew services list would still show redis as "started." The best approach is to use brew services --verbose start redis which will show you that the log file is at /usr/local/var/log/redis.log. Looking in there I found the smoking gun(s)

Fatal error, can't open config file '/usr/local/etc/redis.conf'

or

Can't chdir to '/usr/local/var/db/redis/': No such file or directory

Thankfully the log made the solution above obvious.

Can't I just run redis-server?

You sure can. It'll just take up a terminal or interrupt your terminal occasionally if you run redis-server &. Also it will put dump.rdb in whatever directory you run it in (pwd). I got annoyed having to remove the file or ignore it in git so I figured I'd let brew do the work with services.

Hardcoding a password in an expect script is the same as having a passwordless sudo, actually worse, since sudo at least logs its commands.

From the documentation:

Conditional expressions (sometimes called a “ternary operator”) have the lowest priority of all Python operations.

The expression x if C else y first evaluates the condition, C (not x); if C is true, x is evaluated and its value is returned; otherwise, y is evaluated and its value is returned.

See PEP 308 for more details about conditional expressions.

New since version 2.5.

A lot of people create very strange responses to these questions that make alot more work than necessary.

The easiest way to do this consists of the following

1. Parse JSON String using JSON.parse(value)
2. Stringify Parsed string into a nice format - JSON.stringify(input,undefined,2)
3. Set output to the value of step 2.

In actual code, an example will be (combining all steps together):

    var input = document.getElementById("input").value;
    document.getElementById("output").value = JSON.stringify(JSON.parse(input),undefined,2);

output.value is going to be the area where you will want to display a beautified JSON.

No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

  <xsl:variable name="mapping">
    <item key="1" v1="A" v2="B" />
    <item key="2" v1="X" v2="Y" />
  </xsl:variable>
  <xsl:variable name="mappingNode"
                select="document('')//xsl:variable[@name = 'mapping']" />

  <xsl:template match="....">
    <xsl:variable name="testVariable" select="'1'" />

    <xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />

    <xsl:variable name="variable1" select="$values/@v1" />
    <xsl:variable name="variable2" select="$values/@v2" />
  </xsl:template>
</xsl:stylesheet>

In fact, once you've got the values variable, you may not even need separate variable1 and variable2 variables. You could just use $values/@v1 and $values/@v2 instead.

$('#myform').submit(function() {
  // your code here
})

The above is NOT working in Firefox. The form will just simply submit without running your code first. Also, similar issues are mentioned elsewhere... such as this question. The workaround will be

$('#myform').submit(function(event) {

 event.preventDefault(); //this will prevent the default submit

  // your code here (But not asynchronous code such as Ajax because it does not wait for a response and move to the next line.)
  
 $(this).unbind('submit').submit(); // continue the submit unbind preventDefault
})

Beware of adding 3600!! may be a problem on day change because of unix timestamp format uses moth before day.

e.g. 2012-03-02 23:33:33 would become 2014-01-13 13:00:00 by adding 3600 better use mktime and date functions they can handle this and things like adding 25 hours etc.

Your regex does not work because [] defines a character class, but what you want is a lookahead:

(?=) - Positive look ahead assertion foo(?=bar) matches foo when followed by bar
(?!) - Negative look ahead assertion foo(?!bar) matches foo when not followed by bar
(?<=) - Positive look behind assertion (?<=foo)bar matches bar when preceded by foo
(?<!) - Negative look behind assertion (?<!foo)bar matches bar when NOT preceded by foo
(?>) - Once-only subpatterns (?>\d+)bar Performance enhancing when bar not present
(?(x)) - Conditional subpatterns
(?(3)foo|fu)bar - Matches foo if 3rd subpattern has matched, fu if not

This is the format of /etc/crontab:

# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name  command to be executed

I recommend copy & pasting that into the top of your crontab file so that you always have the reference handy. RedHat systems are setup that way by default.

To run something every minute:

* * * * * username /var/www/html/a.php

To run something at midnight of every day:

0 0 * * * username /var/www/html/reset.php

You can either include /usr/bin/php in the command to run, or you can make the php scripts directly executable:

chmod +x file.php

Start your php file with a shebang so that your shell knows which interpreter to use:

#!/usr/bin/php
<?php
// your code here

split is deprecated since it is part of the family of functions which make use of POSIX regular expressions; that entire family is deprecated in favour of the PCRE (preg_*) functions.

If you do not need the regular expression functionality, then explode is a very good choice (and would have been recommended over split even if that were not deprecated), if on the other hand you do need to use regular expressions then the PCRE alternate is simply preg_split.

I use printf, is shorter as it doesn't need flags to do the work:

printf "\rMy static $myvars composed text"

In case you have a school server where the pupils worked a lot. You can just clean up the mess by:

delete from user where User != 'root' and User != 'admin';
delete from db where User != 'root' and User != 'admin';

delete from tables_priv;
delete from columns_priv;

flush privileges;

this work for me

Now I need to connect that application from my local computer, but I don't know the JMX port number of the remote computer. Where can I find it? Or, must I restart that application with some VM parameters to specify the port number?

By default JMX does not publish on a port unless you specify the arguments from this page: How to activate JMX...

-Dcom.sun.management.jmxremote # no longer required for JDK6
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.local.only=false # careful with security implications
-Dcom.sun.management.jmxremote.authenticate=false # careful with security implications

If you are running you should be able to access any of those system properties to see if they have been set:

if (System.getProperty("com.sun.management.jmxremote") == null) {
    System.out.println("JMX remote is disabled");
} else [
    String portString = System.getProperty("com.sun.management.jmxremote.port");
    if (portString != null) {
        System.out.println("JMX running on port "
            + Integer.parseInt(portString));
    }
}

Depending on how the server is connected, you might also have to specify the following parameter. As part of the initial JMX connection, jconsole connects up to the RMI port to determine which port the JMX server is running on. When you initially start up a JMX enabled application, it looks its own hostname to determine what address to return in that initial RMI transaction. If your hostname is not in /etc/hosts or if it is set to an incorrect interface address then you can override it with the following:

-Djava.rmi.server.hostname=<IP address>

As an aside, my SimpleJMX package allows you to define both the JMX server and the RMI port or set them both to the same port. The above port defined with com.sun.management.jmxremote.port is actually the RMI port. This tells the client what port the JMX server is running on.

Note that, in windows, the pgpass.conf file must be in the following folder:

%APPDATA%\postgresql\pgpass.conf

if there's no postgresql folder inside the %APPDATA% folder, create it.

the pgpass.conf file content is something like:

localhost:5432:dbname:dbusername:dbpassword

You can use rand($min, $max) for that exact purpose.

In order to limit the values to values with x digits you can use the following:

$x = 3; // Amount of digits
$min = pow(10,$x);
$max = pow(10,$x+1)-1);
$value = rand($min, $max);

I want to add something on @Michael Laffargue's post:

jqXHR.done() is faster!

jqXHR.success() have some load time in callback and sometimes can overkill script. I find that on hard way before.

UPDATE:

Using jqXHR.done(), jqXHR.fail() and jqXHR.always() you can better manipulate with ajax request. Generaly you can define ajax in some variable or object and use that variable or object in any part of your code and get data faster. Good example:

/* Initialize some your AJAX function */
function call_ajax(attr){
    var settings=$.extend({
        call            : 'users',
        option          : 'list'
    }, attr );

    return $.ajax({
        type: "POST",
        url: "//exapmple.com//ajax.php",
        data: settings,
        cache : false
    });
}

/* .... Somewhere in your code ..... */

call_ajax({
    /* ... */
    id : 10,
    option : 'edit_user'
    change : {
          name : 'John Doe'
    }
    /* ... */
}).done(function(data){

    /* DO SOMETHING AWESOME */

});

Try using the InStr function which returns the index in the string at which the character was found. If InStr returns 0, the string was not found.

If InStr(myString, "A") > 0 Then

InStr MSDN Website

For the error on the line assigning to newStr, convert oldStr.IndexOf to that InStr function also.

Left(oldStr, InStr(oldStr, "A"))

I have written the following code in my last assignment, it may help you:

// A method that converts the nano-seconds to Seconds-Minutes-Hours form
private static String formatTime(long nanoSeconds)
{
    int hours, minutes, remainder, totalSecondsNoFraction;
    double totalSeconds, seconds;


    // Calculating hours, minutes and seconds
    totalSeconds = (double) nanoSeconds / 1000000000.0;
    String s = Double.toString(totalSeconds);
    String [] arr = s.split("\\.");
    totalSecondsNoFraction = Integer.parseInt(arr[0]);
    hours = totalSecondsNoFraction / 3600;
    remainder = totalSecondsNoFraction % 3600;
    minutes = remainder / 60;
    seconds = remainder % 60;
    if(arr[1].contains("E")) seconds = Double.parseDouble("." + arr[1]);
    else seconds += Double.parseDouble("." + arr[1]);


    // Formatting the string that conatins hours, minutes and seconds
    StringBuilder result = new StringBuilder(".");
    String sep = "", nextSep = " and ";
    if(seconds > 0)
    {
        result.insert(0, " seconds").insert(0, seconds);
        sep = nextSep;
        nextSep = ", ";
    }
    if(minutes > 0)
    {
        if(minutes > 1) result.insert(0, sep).insert(0, " minutes").insert(0, minutes);
        else result.insert(0, sep).insert(0, " minute").insert(0, minutes);
        sep = nextSep;
        nextSep = ", ";
    }
    if(hours > 0)
    {
        if(hours > 1) result.insert(0, sep).insert(0, " hours").insert(0, hours);
        else result.insert(0, sep).insert(0, " hour").insert(0, hours);
    }
    return result.toString();
}

Just convert nano-seconds to milli-seconds.

Note: I am not happy with previous answers, (not working on all systems, not working on remote, not specifying the --merged branch, not filtering exactly). So, I add my own answer.

There are two main cases:

Local

You want to delete local branches that are already merged to another local branch. During the deletion, you want to keep some important branches, like master, develop, etc.

git branch --format "%(refname:short)" --merged master | grep -E -v '^master$|^feature/develop$' | xargs -n 1 git branch -d

Notes:

• git branch output --format ".." is to strip whitespaces and allow exact grep matching
• grep -E is used instead of egrep, so it works also in systems without egrep (i.e.: git for windows).
• grep -E -v '^master$|^feature/develop$' is to specify local branches that I don't want to delete
• xargs -n 1 git branch -d: perform the deletion of local branches (it won't work for remote ones)
• of course you get an error if you try deleting the branch currently checked-out. So, I suggest to switch to master beforehand.

Remote

You want to delete remote branches that are already merged to another remote branch. During the deletion, you want to keep some important branches, like HEAD, master, releases, etc.

git branch -r --format "%(refname:short)" --merged origin/master | grep -E -v '^*HEAD$|^*/master$|^*release' | cut -d/ -f2- | xargs -n 1 git push --delete origin

Notes:

• for remote, we use the -r option and provide the full branch name: origin/master
• grep -E -v '^*HEAD$|^*/master$|^*release' is to match the remote branches that we don't want to delete.
• cut -d/ -f2- : remove the unneeded 'origin/' prefix that otherwise is printed out by the git branch command.
• xargs -n 1 git push --delete origin : perform the deletion of remote branches.

Components cannot be further (From Angular 9) imported through general directory

you should add a specified component path like

import {} from '@angular/material'; 

import {} from '@angular/material/input';

A more appropriate method is to use std::cin.ignore:

#include <iostream>

void Pause()
{
   std::cout << "Press Enter to continue...";
   std::cout.flush();
   std::cin.ignore(10000, '\n');
   return;
}

We had an issue relating to duplicated data in our database, with a date field having multiple values where we were meant to have 1. I thought I'd add the way we resolved the issue for reference.

We have a collection called "data" with a numeric "value" field and a date "date" field. We had a process which we thought was idempotent, but ended up adding 2 x values per day on second run:

{ "_id" : "1", "type":"x", "value":1.23, date : ISODate("2013-05-21T08:00:00Z")}
{ "_id" : "2", "type":"x", "value":1.23, date : ISODate("2013-05-21T17:00:00Z")}

We only need 1 of the 2 records, so had to resort the javascript to clean up the db. Our initial approach was going to be to iterate through the results and remove any field with a time of between 6am and 11am (all duplicates were in the morning), but during implementation, made a change. Here's the script used to fix it:

var data = db.data.find({"type" : "x"})
var found = [];
while (data.hasNext()){
    var datum = data.next();
    var rdate = datum.date;
    // instead of the next set of conditions, we could have just used rdate.getHour() and checked if it was in the morning, but this approach was slightly better...
    if (typeof found[rdate.getDate()+"-"+rdate.getMonth() + "-" + rdate.getFullYear()] !== "undefined") {
       if (datum.value != found[rdate.getDate()+"-"+rdate.getMonth() + "-" + rdate.getFullYear()]) {
           print("DISCREPENCY!!!: " + datum._id + " for date " + datum.date);
       }
       else {
           print("Removing " + datum._id);
           db.data.remove({ "_id": datum._id});
       }
    }
    else {
       found[rdate.getDate()+"-"+rdate.getMonth() + "-" + rdate.getFullYear()] = datum.value;
    }
}

and then ran it with mongo thedatabase fixer_script.js

User agent sniffing is really tricky and unreliable. We were trying to detect Safari on iOS with something like @qingu's answer above, it did work pretty well for Safari, Chrome and Firefox. But it falsely detected Opera and Edge as Safari.

So we went with feature detection, as it looks like as of today, serviceWorker is only supported in Safari and not in any other browser on iOS. As stated in https://jakearchibald.github.io/isserviceworkerready/

Support does not include iOS versions of third-party browsers on that platform (see Safari support).

So we did something like

if ('serviceWorker' in navigator) {
    return 'Safari';
}
else {
    return 'Other Browser';
}

Note: Not tested on Safari on MacOS.

The closest thing would be the bind function:

http://api.jquery.com/bind/

$('#foo').bind('click', function() {
  alert('User clicked on "foo."');
});

In order to generate key hash you need to follow some easy steps.

1) Download Openssl from: here.

2) Make a openssl folder in C drive

3) Extract Zip files into this openssl folder created in C Drive.

4) Copy the File debug.keystore from .android folder in my case (C:\Users\SYSTEM.android) and paste into JDK bin Folder in my case (C:\Program Files\Java\jdk1.6.0_05\bin)

5) Open command prompt and give the path of JDK Bin folder in my case (C:\Program Files\Java\jdk1.6.0_05\bin).

6) Copy the following code and hit enter

keytool -exportcert -alias androiddebugkey -keystore debug.keystore > c:\openssl\bin\debug.txt

7) Now you need to enter password, Password = android.

8) If you see in openssl Bin folder, you will get a file with the name of debug.txt

9) Now either you can restart command prompt or work with existing command prompt

10) get back to C drive and give the path of openssl Bin folder

11) copy the following code and paste

openssl sha1 -binary debug.txt > debug_sha.txt

12) you will get debug_sha.txt in openssl bin folder

13) Again copy following code and paste

openssl base64 -in debug_sha.txt > debug_base64.txt

14) you will get debug_base64.txt in openssl bin folder

15) open debug_base64.txt file Here is your Key hash.

We need to specify the INITIAL_CONTEXT_FACTORY, PROVIDER_URL, USERNAME, PASSWORD etc. of JNDI to create an InitialContext.

In a standalone application, you can specify that as below

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, 
    "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://ldap.wiz.com:389");
env.put(Context.SECURITY_PRINCIPAL, "joeuser");
env.put(Context.SECURITY_CREDENTIALS, "joepassword");

Context ctx = new InitialContext(env);

But if you are running your code in a Java EE container, these values will be fetched by the container and used to create an InitialContext as below

System.getProperty(Context.PROVIDER_URL);

and

these values will be set while starting the container as JVM arguments. So if you are running the code in a container, the following will work

InitialContext ctx = new InitialContext();

For reference, here's an sscce that illustrates the difference. Console:

            }
        });
        JPanel p = new JPanel();
        p.add(b);
        f.add(p);
        f.pack();

www.somedomain.com is the domain/host. The subdomain is an important part. www. is often used interchangeably with not having one, but that has to be set up as a rule (even if it's set by default) because they are not equivalent. Think of another subdomain, like mx.. That probably has a different target than www..

Given that, I'd advise not doing this sort of thing. That said, since you're asking I imagine you have a good reason.

Personally, I'd suggest special-casing www. for this.

string host = HttpContext.Current.Request.Url.GetComponents(UriComponents.HostAndPort, UriFormat.Unescaped);;

if (host.StartsWith("www."))
    return host.Substring(4);
else
    return host;

Otherwise, if you're really 100% sure that you want to chop off any subdomain, you'll need something a tad more complicated.

string host = ...;

int lastDot = host.LastIndexOf('.');

int secondToLastDot = host.Substring(0, lastDot).LastIndexOf('.');

if (secondToLastDot > -1)
    return host.Substring(secondToLastDot + 1);
else
    return host;

Getting the port is just like other people have said.

Honestly, I'm surprised how nobody thought about the git push command:

git push -f . <destination>:<branch>

The dot ( . ) refers the local repository, and you may need the -f option because the destination could be "behind its remote counterpart".

Although this command is used to save your changes in your server, the result is exactly the same as if moving the remote branch (<branch>) to the same commit as the local branch (<destination>)

I had the same problem. SSMS launches the 32bit version of the import and export wizard which has this issue. Try launching the 64bit version application and it should work fine.

One difference from a debugging perspective:

To debug into Java system classes such as String and ArrayList, you need a special version of the JRE which is compiled with "debug information". The JRE included inside the JDK provides this info, but the regular JRE does not. Regular JRE does not include this info to ensure better performance.

What is debugging information? Here is a quick explanation taken from this blog post:

Modern compilers do a pretty good job converting your high-level code, with its nicely indented and nested control structures and arbitrarily typed variables into a big pile of bits called machine code (or bytecode in case of Java), the sole purpose of which is to run as fast as possible on the target CPU (virtual CPU of your JVM). Java code gets converted into several machine code instructions. Variables are shoved all over the place – into the stack, into registers, or completely optimized away. Structures and objects don’t even exist in the resulting code – they’re merely an abstraction that gets translated to hard-coded offsets into memory buffers.

So how does a debugger know where to stop when you ask it to break at the entry to some function? How does it manage to find what to show you when you ask it for the value of a variable? The answer is – debugging information.

Debugging information is generated by the compiler together with the machine code. It is a representation of the relationship between the executable program and the original source code. This information is encoded into a pre-defined format and stored alongside the machine code. Many such formats were invented over the years for different platforms and executable files.

Use java.utils.Arrays:

public int getTheNumber(int[] factors) {
    int[] f = (int[])factors.clone();
    Arrays.sort(f);
    return f[0]*f[(f.length-1];
}

Or if you want to be efficient avoid all the object allocation just actually do the work:

public static int getTheNumber(int[] array) {
    if (array.length == 0)
        throw new IllegalArgumentException();
    int min = array[0];
    int max = array[0];
    for (int i = 1; i< array.length;++i) {
        int v = array[i];
        if (v < min) {
            min = v;
        } else if (v > max) {
            max = v;
        }
    }
    return min * max;
}

There is an option to generate php5 objects with WsdlInterpreter class. See more here: https://github.com/gkwelding/WSDLInterpreter

for example:

require_once 'WSDLInterpreter-v1.0.0/WSDLInterpreter.php';
$wsdlLocation = '<your wsdl url>?wsdl';
$wsdlInterpreter = new WSDLInterpreter($wsdlLocation);
$wsdlInterpreter->savePHP('.');

If you have a PC with internet access in your LAN, you should install a local Maven repository.

I recommend Artifactory Open Source. This is what we use in our organization, it is really easy to setup.

Artifactory acts as a proxy between your build tool (Maven, Ant, Ivy, Gradle etc.) and the outside world.

It caches remote artifacts so that you don’t have to download them over and over again.

It blocks unwanted (and sometimes security-sensitive) external requests for internal artifacts and controls how and where artifacts are deployed, and by whom.

After setting up Artifactory you just need to change Maven's settings.xml in the development machines:

<?xml version="1.0" encoding="UTF-8"?>
<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd" xmlns="http://maven.apache.org/SETTINGS/1.0.0"

We used this solution because we had problems with internet access in our development machines and some artifacts downloaded corrupted files or didn't download at all. We haven't had problems since.

From the page es6-features.org/#ClassInheritanceFromExpressions, it is possible to write an aggregation function to allow multiple inheritance:

class Rectangle extends aggregation(Shape, Colored, ZCoord) {}

var aggregation = (baseClass, ...mixins) => {
    let base = class _Combined extends baseClass {
        constructor (...args) {
            super(...args)
            mixins.forEach((mixin) => {
                mixin.prototype.initializer.call(this)
            })
        }
    }
    let copyProps = (target, source) => {
        Object.getOwnPropertyNames(source)
            .concat(Object.getOwnPropertySymbols(source))
            .forEach((prop) => {
            if (prop.match(/^(?:constructor|prototype|arguments|caller|name|bind|call|apply|toString|length)$/))
                return
            Object.defineProperty(target, prop, Object.getOwnPropertyDescriptor(source, prop))
        })
    }
    mixins.forEach((mixin) => {
        copyProps(base.prototype, mixin.prototype)
        copyProps(base, mixin)
    })
    return base
}

But that is already provided in libraries like aggregation.

Alternatively You can use:

mystring = 'banana'
number = mystring.count('a')

If the checkbox is checked, then the checkbox's value will be passed. Otherwise, the field is not passed in the HTTP post.

if (isset($_POST['mycheckbox'])) {
    echo "checked!";
}

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.

So, there will be no major difference how "use strict"; is interpreted by the Chrome browser and Node.js.

Please read what is strict mode in JavaScript.

For more information:

1. Strict mode
2. ECMAScript 5 Strict mode support in browsers
3. Strict mode is coming to town
4. Compatibility table for strict mode
5. Stack Overflow questions: what does 'use strict' do in JavaScript & what is the reasoning behind it

ECMAScript 6 Code & strict mode. Following is brief from the specification:

10.2.1 Strict Mode Code

An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:

• Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
• Module code is always strict mode code.
• All parts of a ClassDeclaration or a ClassExpression are strict mode code.
• Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
• Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
• Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

Additionally if you are lost on what features are supported by your current version of Node.js, this node.green can help you (leverages from the same data as kangax).

I think you want to specify

-H "Content-Type:text/xml"

with a colon, not an equals.

If you are using yum try:

sudo yum install mysql-devel

I am not sure if u have found the answer, but I did this and it works

public IEnumerable<string> Get()
{
    return new string[] { "value1", "value2" };
}

// GET /api/values/5
public string Get(int id)
{
    return "value";
}

// GET /api/values/5
[HttpGet]
public string GetByFamily()
{
    return "Family value";
}

Now in global.asx

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.MapHttpRoute(
    name: "DefaultApi2",
    routeTemplate: "api/{controller}/{action}",
    defaults: new { id = RouteParameter.Optional }
);

routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

I face the same issue and this worked for me!

Install jQuery using npm

$ npm install jquery

Then include jQuery in one of the following ways.

Using script tag

<script>window.$ = window.jQuery = require('jquery');</script>

Using Babel

import $ from 'jquery';

Using Webpack

const $ = require('jquery');

After two dozens of comments to understand the situation, it was found that the libhdf5.so.7 was actually a symlink (with several levels of indirection) to a file that was not shared between the queued processes and the interactive processes. This means even though the symlink itself lies on a shared filesystem, the contents of the file do not and as a result the process was seeing different versions of the library.

For future reference: other than checking LD_LIBRARY_PATH, it's always a good idea to check a library with nm -D to see if the symbols actually exist. In this case it was found that they do exist in interactive mode but not when run in the queue. A quick md5sum revealed that the files were actually different.

I think thats impossible, sorry.

Thats why whenever running a delete or update you should always use BEGIN TRANSACTION, then COMMIT if successful or ROLLBACK if not.

Taking a combination of @sawa's answer and the comment listed there you could implement a "quick" index and rindex on the array class.

class Array
  def quick_index el
    hash = Hash[self.map.with_index.to_a]
    hash[el]
  end

  def quick_rindex el
    hash = Hash[self.reverse.map.with_index.to_a]
    array.length - 1 - hash[el]
  end
end

See my answer to a similar question here.

It sounds like you want a background-image to keep it's own aspect ratio while expanding to 100% width and getting cropped off on the top and bottom. If that's the case, do something like this:

.chapter {
    position: relative;
    height: 1200px;
    z-index: 1;
}

#chapter1 {
    background-image: url(http://omset.files.wordpress.com/2010/06/homer-simpson-1-264a0.jpg);
    background-repeat: no-repeat;
    background-size: 100% auto;
    background-position: center top;
    background-attachment: fixed;
}

jsfiddle: http://jsfiddle.net/ndKWN/3/

The problem with this approach is that you have the container elements at a fixed height, so there can be space below if the screen is small enough.

If you want the height to keep the image's aspect ratio, you'll have to do something like what I wrote in an edit to the answer I linked to above. Set the container's height to 0 and set the padding-bottom to the percentage of the width:

.chapter {
    position: relative;
    height: 0;
    padding-bottom: 75%;
    z-index: 1;
}

#chapter1 {
    background-image: url(http://omset.files.wordpress.com/2010/06/homer-simpson-1-264a0.jpg);
    background-repeat: no-repeat;
    background-size: 100% auto;
    background-position: center top;
    background-attachment: fixed;
}

jsfiddle: http://jsfiddle.net/ndKWN/4/

You could also put the padding-bottom percentage into each #chapter style if each image has a different aspect ratio. In order to use different aspect ratios, divide the height of the original image by it's own width, and multiply by 100 to get the percentage value.

While the answers that are already here work well, I found that they were slightly slower than I had hoped for. Instead I used zip4j, which I think is the best solution because of its speed. It also allowed for different options for the amount of compression, which I found useful.

There is a nice form plugin that allows you to send an HTML form asynchroniously.

$(document).ready(function() { 
    $('#myForm1').ajaxForm(); 
});

or

$("select").change(function(){
    $('#myForm1').ajaxSubmit();
});

to submit the form immediately

I had set the new app's application pool to the DefaultAppPool in IIS which obviously is using the Classic pipeline with .NET v.2.0.

To solve the problem I created a new App Pool using the Integrated pipeline and .NET v4.0. just for this new application and then everything started working as expected.

Don't forget to assign this new app pool to the application. Select the application in IIS, click Basic Settings and then pick the new app pool for the app.

Try initializing your variables and use them in your connection object:

$username ="root";
$password = "password";
$host = "localhost";
$table = "shop";
$conn = new mysqli("$host", "$username", "$password", "$table");

To replace from the right:

def replace_right(source, target, replacement, replacements=None):
    return replacement.join(source.rsplit(target, replacements))

In use:

>>> replace_right("asd.asd.asd.", ".", ". -", 1)
'asd.asd.asd. -'

Java seems to have a bias towards using double for computations nonetheless:

Case in point the program I wrote earlier today, the methods didn't work when I used float, but now work great when I substituted float with double (in the NetBeans IDE):

package palettedos;
import java.util.*;

class Palettedos{
    private static Scanner Z = new Scanner(System.in);
    public static final double pi = 3.142;

    public static void main(String[]args){
        Palettedos A = new Palettedos();
        System.out.println("Enter the base and height of the triangle respectively");
        int base = Z.nextInt();
        int height = Z.nextInt();
        System.out.println("Enter the radius of the circle");
        int radius = Z.nextInt();
        System.out.println("Enter the length of the square");
        long length = Z.nextInt();
        double tArea = A.calculateArea(base, height);
        double cArea = A.calculateArea(radius);
        long sqArea = A.calculateArea(length);
        System.out.println("The area of the triangle is\t" + tArea);
        System.out.println("The area of the circle is\t" + cArea);
        System.out.println("The area of the square is\t" + sqArea);
    }

    double calculateArea(int base, int height){
        double triArea = 0.5*base*height;
        return triArea;
    }

    double calculateArea(int radius){
        double circArea = pi*radius*radius;
        return circArea;
    }

    long calculateArea(long length){
        long squaArea = length*length;
        return squaArea;
    }
}

I solved this problem by typing in the Module name (unfortunately the drop list will show nothing...) in the Custom Class of the identity inspector for all the View controller and views.

You may also need to indicate the target provider. To achieve this objective you can open the storyboard in sourcecode mode and add the "customModuleProvider" attribute in both ViewController and View angle brackets.

Of course.

$('#item')[0].className = '';
// or
document.getElementById('item').className = '';

From ioS 7 onwards, there are newer ways for apps to run in background. Apple now recognizes that apps have to constantly download and process data constantly.

Here is the new list of all the apps which can run in background.

1. Apps that play audible content to the user while in the background, such as a music player app
2. Apps that record audio content while in the background.
3. Apps that keep users informed of their location at all times, such as a navigation app
4. Apps that support Voice over Internet Protocol (VoIP)
5. Apps that need to download and process new content regularly
6. Apps that receive regular updates from external accessories

You can declare app's supported background tasks in Info.plist using X Code 5+. For eg. adding UIBackgroundModes key to your app’s Info.plist file and adding a value of 'fetch' to the array allows your app to regularly download and processes small amounts of content from the network. You can do the same in the 'capabilities' tab of Application properties in XCode 5 (attaching a snapshot)

You can find more about this in Apple documentation

What is that BasePagerAdapter? You should use one of the standard pager adapters -- either FragmentPagerAdapter or FragmentStatePagerAdapter, depending on whether you want Fragments that are no longer needed by the ViewPager to either be kept around (the former) or have their state saved (the latter) and re-created if needed again.

Sample code for using ViewPager can be found here

It is true that the management of fragments in a view pager across activity instances is a little complicated, because the FragmentManager in the framework takes care of saving the state and restoring any active fragments that the pager has made. All this really means is that the adapter when initializing needs to make sure it re-connects with whatever restored fragments there are. You can look at the code for FragmentPagerAdapter or FragmentStatePagerAdapter to see how this is done.

Keeping it simple, use Java's String.replaceAll() method as follows:

String fileNameWithExt = "test.xml";
String fileNameWithoutExt
   = fileNameWithExt.replaceAll( "^.*?(([^/\\\\\\.]+))\\.[^\\.]+$", "$1" );

This also works when fileNameWithExt includes the fully qualified path.

You can listen file changes using a FileReader. Plz see the example below

// File content change listener 
private String fname;
private Object lck = new Object();
... 
public void run()
{
    try
    {
        BufferedReader br = new BufferedReader( new FileReader( fname ) );
        String s;
        StringBuilder buf = new StringBuilder();
        while( true )
        {
            s = br.readLine();
            if( s == null )
            {
                synchronized( lck )
                {
                    lck.wait( 500 );
                }
            }
            else
            {
               System.out.println( "s = " + s );
            }

        }
    }
    catch( Exception e )
    {
        e.printStackTrace();
    }
}

Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -sign before value:

ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) + 
  geom_bar(stat = "identity")

which gives:

Used data:

corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
                         variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
                         value = c(7L, 75L, 70L, 5L, 10L, 47L)),
                    class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))

Are you using MySQL or PostgreSQL?

You want to use JOIN syntax, not UNION. For example, using INNER JOIN:

CREATE VIEW V AS
SELECT POP.country, POP.year, POP.pop, FOOD.food, INCOME.income
FROM POP
INNER JOIN FOOD ON (POP.country=FOOD.country) AND (POP.year=FOOD.year)
INNER JOIN INCOME ON (POP.country=INCOME.country) AND (POP.year=INCOME.year)

However, this will only show results when each country and year are present in all three tables. If this is not what you want, look into left outer joins (using the same link above).

You can raise a notice in Postgres as follows:

raise notice 'Value: %', deletedContactId;

In ECMAScript 2021, you can use replaceAll can be used.

const str = "string1 string1 string1"
const newStr = str.replaceAll("string1", "string2");

console.log(newStr)
//  "string2 string2 string2"

It won't throw exception, you'll get an empty list.

Swift 5 The easiest way to add permissions without having to do it programatically, is to open your info.plist file and select the + next to Information Property list. Scroll through the drop down list to the Privacy options and select Privacy Camera Usage Description for accessing camera, or Privacy Photo Library Usage Description for accessing the Photo Library. Fill in the String value on the right after you've made your selection, to include the text you would like displayed to your user when the alert pop up asks for permissions.

My default browser is Google Chrome and the accepted answer is giving the following error:

The system cannot find the file specified.

I solved the problem and managed to open an URL with the default browser by using this code:

System.Diagnostics.Process.Start("explorer.exe", "http://google.com");

You can use the struct's pack:

In [11]: struct.pack(">I", 1)
Out[11]: '\x00\x00\x00\x01'

The ">" is the byte-order (big-endian) and the "I" is the format character. So you can be specific if you want to do something else:

In [12]: struct.pack("<H", 1)
Out[12]: '\x01\x00'

In [13]: struct.pack("B", 1)
Out[13]: '\x01'

This works the same on both python 2 and python 3.

Note: the inverse operation (bytes to int) can be done with unpack.

There is more than one type of UUID, so "how safe" depends on which type (which the UUID specifications call "version") you are using.

• Version 1 is the time based plus MAC address UUID. The 128-bits contains 48-bits for the network card's MAC address (which is uniquely assigned by the manufacturer) and a 60-bit clock with a resolution of 100 nanoseconds. That clock wraps in 3603 A.D. so these UUIDs are safe at least until then (unless you need more than 10 million new UUIDs per second or someone clones your network card). I say "at least" because the clock starts at 15 October 1582, so you have about 400 years after the clock wraps before there is even a small possibility of duplications.

• Version 4 is the random number UUID. There's six fixed bits and the rest of the UUID is 122-bits of randomness. See Wikipedia or other analysis that describe how very unlikely a duplicate is.

• Version 3 is uses MD5 and Version 5 uses SHA-1 to create those 122-bits, instead of a random or pseudo-random number generator. So in terms of safety it is like Version 4 being a statistical issue (as long as you make sure what the digest algorithm is processing is always unique).

• Version 2 is similar to Version 1, but with a smaller clock so it is going to wrap around much sooner. But since Version 2 UUIDs are for DCE, you shouldn't be using these.

So for all practical problems they are safe. If you are uncomfortable with leaving it up to probabilities (e.g. your are the type of person worried about the earth getting destroyed by a large asteroid in your lifetime), just make sure you use a Version 1 UUID and it is guaranteed to be unique (in your lifetime, unless you plan to live past 3603 A.D.).

So why doesn't everyone simply use Version 1 UUIDs? That is because Version 1 UUIDs reveal the MAC address of the machine it was generated on and they can be predictable -- two things which might have security implications for the application using those UUIDs.

After not able to find a good universal solution I made something of my own. I have not tested it for a very large list.

It takes care of nested keys,arrays or just about anything.

Here is the github and demo

app.filter('xf', function() {
    function keyfind(f, obj) {
        if (obj === undefined)
            return -1;
        else {
            var sf = f.split(".");
            if (sf.length <= 1) {
                return obj[sf[0]];
            } else {
                var newobj = obj[sf[0]];
                sf.splice(0, 1);
                return keyfind(sf.join("."), newobj)
            }
        }

    }
    return function(input, clause, fields) {
        var out = [];
        if (clause && clause.query && clause.query.length > 0) {
            clause.query = String(clause.query).toLowerCase();
            angular.forEach(input, function(cp) {
                for (var i = 0; i < fields.length; i++) {
                    var haystack = String(keyfind(fields[i], cp)).toLowerCase();
                    if (haystack.indexOf(clause.query) > -1) {
                        out.push(cp);
                        break;
                    }
                }
            })
        } else {
            angular.forEach(input, function(cp) {
                out.push(cp);
            })
        }
        return out;
    }

})

As you noticed, these are Makefile {macros or variables}, not compiler options. They implement a set of conventions. (Macros is an old name for them, still used by some. GNU make doc calls them variables.)

The only reason that the names matter is the default make rules, visible via make -p, which use some of them.

If you write all your own rules, you get to pick all your own macro names.

In a vanilla gnu make, there's no such thing as CCFLAGS. There are CFLAGS, CPPFLAGS, and CXXFLAGS. CFLAGS for the C compiler, CXXFLAGS for C++, and CPPFLAGS for both.

Why is CPPFLAGS in both? Conventionally, it's the home of preprocessor flags (-D, -U) and both c and c++ use them. Now, the assumption that everyone wants the same define environment for c and c++ is perhaps questionable, but traditional.

P.S. As noted by James Moore, some projects use CPPFLAGS for flags to the C++ compiler, not flags to the C preprocessor. The Android NDK, for one huge example.

ExecuteNonQuery method will return number of rows effected with INSERT, DELETE or UPDATE operations. This ExecuteNonQuery method will be used only for insert, update and delete, Create, and SET statements. (Read More)

ExecuteScalar will return single row single column value i.e. single value, on execution of SQL Query or Stored procedure using command object. It’s very fast to retrieve single values from database. (Read More)

ExecuteReader will be used to return the set of rows, on execution of SQL Query or Stored procedure using command object. This one is forward only retrieval of records and it is used to read the table values from first to last. (Read More)

TLDR for people comming from c++

It's just overloaded operator of ( ) parentheses

So in scala:

class X {
   def apply(param1: Int, param2: Int, param3: Int) : Int = {
     // Do something
   }
}

Is same as this in c++:

class X {
   int operator()(int param1, int param2, int param3) {
      // do something
   }
};

Write below code in script and also add jQuery library

var getElement = document.getElementById('myID');

if (document.activeElement === getElement) {
        $(document).keydown(function(event) {
            if (event.which === 40) {
                console.log('keydown pressed')
            }
        });
    }

Thank you...

In addition with what @Camilo Silva already mentioned, if you want to give free access to create databases, read, write databases, etc, but you don't want to create a root role, you can change the 3rd step with the following:

use admin
db.createUser(
  {
    user: "myUserAdmin",
    pwd: "abc123",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" }, 
             { role: "dbAdminAnyDatabase", db: "admin" }, 
             { role: "readWriteAnyDatabase", db: "admin" } ]
  }
)

Why don't you simply move the code you have in the ApiController calls - DocumentsController to a class that you can call from both your HomeController and DocumentController. Pull this out into a class you call from both controllers. This stuff in your question:

// All code to find the files are here and is working perfectly...

It doesn't make sense to call a API Controller from another controller on the same website.

This will also simplify the code when you come back to it in the future you will have one common class for finding the files and doing that logic there...

Set is an Keyword and it is used to assign a reference to an Object in VBA.

For E.g., *Below example shows how to use of Set in VBA.

Dim WS As Worksheet

Set WS = ActiveWorkbook.Worksheets("Sheet1")

WS.Name = "Amit"

By using exploits or on badly configured servers it could be possible to download your PHP source. You could however either obfuscate and/or encrypt your code (using Zend Guard, Ioncube or a similar app) if you want to make sure your source will not be readable (to be accurate, obfuscation by itself could be reversed given enough time/resources, but I haven't found an IonCube or Zend Guard decryptor yet...).

Another option like Gavin Palmer answer is to use the .pem file but with a curl option

1. download the last updated .pem file from https://curl.haxx.se/docs/caextract.html and save it somewhere on your server(outside the public folder)

2. set the option in your code instead of the php.ini file.

In your code

curl_setopt($ch, CURLOPT_CAINFO, $_SERVER['DOCUMENT_ROOT'] .  "/../cacert-2017-09-20.pem");

NOTE: setting the cainfo in the php.ini like @Gavin Palmer did is better than setting it in your code like I did, because it will save a disk IO every time the function is called, I just make it like this in case you want to test the cainfo file on the fly instead of changing the php.ini while testing your function.

I had the same problem, but i solved it from Java Control Panel-->Security-->SecurityLevel:MEDIUM. Just so, no Manage certificates, imports ,exports etc..

This was how added my headers in my flask application and it worked perfectly

@app.after_request
def add_header(response):
    response.headers['X-Content-Type-Options'] = 'nosniff'
    return response

I'm using dictionaries as a sort of "database", so I need to find a key that I can reuse. For my case, if a key's value is None, then I can take it and reuse it without having to "allocate" another id. Just figured I'd share it.

db = {0:[], 1:[], ..., 5:None, 11:None, 19:[], ...}

keys_to_reallocate = [None]
allocate.extend(i for i in db.iterkeys() if db[i] is None)
free_id = keys_to_reallocate[-1]

I like this one because I don't have to try and catch any errors such as StopIteration or IndexError. If there's a key available, then free_id will contain one. If there isn't, then it will simply be None. Probably not pythonic, but I really didn't want to use a try here...

Use conda init

As pointed out in a different answer, manually adding Conda on $PATH is no longer recommended as of v4.4.0 (see Release Notes). Furthermore, since Conda v4.6 new functionality to manage shell initialization via the conda init command was introduced. Hence, the updated recommendation is to run

Linux/UNIX (OS X < 10.15)

./anaconda3/bin/conda init

Mac OS X >= 10.15

./anaconda3/bin/conda init zsh

Windows

./anaconda3/Scripts/conda.exe init

You must launch a new shell or source your init file (e.g., source .bashrc) for the changes to take effect.

Alternative shells

You may need to explicitly identify your shell to Conda. For example, if you run zsh (Mac OS X 10.15+ default) instead of bash then you would run

./anaconda3/bin/conda init zsh

Please see ./anaconda3/bin/conda init --help for a comprehensive list of supported shells.

Word of Caution

I'd recommend running the above command with a --dry-run|-d flag and a verbosity (-vv) flag, in order to see exactly what it would do. If you don't already have a Conda-managed section in your shell run commands file (e.g., .bashrc), then this should appear like a straight-forward insertion of some new lines. If it isn't such a straightforward insertion, I'd recommend clearing any previous Conda sections from $PATH and the relevant shell initialization files (e.g., bashrc) first.

Potential Automated Cleanup

Conda v4.6.9 introduced a --reverse flag that automates removing the changes that are inserted by conda init.

Follow the steps below:

• Go to menu Tools
• Go to Options
• Go to the Text Editor options
• Click the language of your choice. I used C# as an example.

See the below image:

try this for close app

Activity.finish();
System.exit(0);

Using WAMP click on wamp icon ->apache->apache modules->scroll and check rewrite_module Restart a LoadModule rewrite_module

Note, the server application restarts automatically for you once you enable "rewrite_module"

Use usort() and a custom comparison function:

function date_compare($a, $b)
{
    $t1 = strtotime($a['datetime']);
    $t2 = strtotime($b['datetime']);
    return $t1 - $t2;
}    
usort($array, 'date_compare');

EDIT: Your data is organized in an array of arrays. To better distinguish those, let's call the inner arrays (data) records, so that your data really is an array of records.

usort will pass two of these records to the given comparison function date_compare() at a a time. date_compare then extracts the "datetime" field of each record as a UNIX timestamp (an integer), and returns the difference, so that the result will be 0 if both dates are equal, a positive number if the first one ($a) is larger or a negative value if the second argument ($b) is larger. usort() uses this information to sort the array.

Kevin Sliech provided a great solution.

I now use the below code in my main UIViewController subclass.

One small alteration i made was to check to see if the best presentation controller is not a plain UIViewController. If not, it's got to be some VC that presents a plain VC. Thus we return the VC that's being presented instead.

- (UIViewController *)bestPresentationController
{
    UIViewController *bestPresentationController = [UIApplication sharedApplication].keyWindow.rootViewController;

    if (![bestPresentationController isMemberOfClass:[UIViewController class]])
    {
        bestPresentationController = bestPresentationController.presentedViewController;
    }    

    return bestPresentationController;
}

Seems to all work out so far in my testing.

Thank you Kevin!

You will get this if you are running the commands from the python shell:

>>> __file__
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name '__file__' is not defined

You need to execute the file directly, by passing it in as an argument to the python command:

$ python somefile.py

In your case, it should really be python setup.py install

You can pass the configuration name to the post-build script and check it in there to see if it should run.

Pass the configuration name with $(ConfigurationName).

Checking it is based on how you are implementing the post-build step -- it will be a command-line argument.

From the release news of ggplot 2.2.0: "The main plot title is now left-aligned to better work better with a subtitle". See also the plot.title argument in ?theme: "left-aligned by default".

As pointed out by @J_F, you may add theme(plot.title = element_text(hjust = 0.5)) to center the title.

ggplot() +
  ggtitle("Default in 2.2.0 is left-aligned")

ggplot() +
  ggtitle("Use theme(plot.title = element_text(hjust = 0.5)) to center") +
  theme(plot.title = element_text(hjust = 0.5))

This looks like a behavior difference in the handling of \s between grep 2.5 and newer versions (a bug in old grep?). I confirm your result with grep 2.5.4, but all four of your greps do work when using grep 2.6.3 (Ubuntu 10.10).

Note:

GNU grep 2.5.4
echo "foo bar" | grep "\s"
   (doesn't match)

whereas

GNU grep 2.6.3
echo "foo bar" | grep "\s"
foo bar

Probably less trouble (as \s is not documented):

Both GNU greps
echo "foo bar" | grep "[[:space:]]"
foo bar

My advice is to avoid using \s ... use [ \t]* or [[:space:]] or something like it instead.

Only View File Adjust like this. You may try this.

@Html.FormatValue( (object)Convert.ChangeType(item.transdate, typeof(object)), 
                            "{0: yyyy-MM-dd}")

item.transdate it is your DateTime type data.

Try apachectl -V:

$ apachectl -V
Server version: Apache/2.2.9 (Unix)
Server built:   Sep 18 2008 21:54:05
Server's Module Magic Number: 20051115:15
Server loaded:  APR 1.2.7, APR-Util 1.2.7
Compiled using: APR 1.2.7, APR-Util 1.2.7
... etc ...

If it does not work for you, run the command with sudo.

df.insert(0, 'New_ID', range(880, 880 + len(df)))
df

I'd recommend adopting Syslog severity levels: DEBUG, INFO, NOTICE, WARNING, ERROR, CRITICAL, ALERT, EMERGENCY.
See http://en.wikipedia.org/wiki/Syslog#Severity_levels

They should provide enough fine-grained severity levels for most use-cases and are recognized by existing log-parsers. While you have of course the freedom to only implement a subset, e.g. DEBUG, ERROR, EMERGENCY depending on your app's requirements.

Let's standardize on something that's been around for ages instead of coming up with our own standard for every different app we make. Once you start aggregating logs and are trying to detect patterns across different ones it really helps.

You can use it with the arrow function as well like as below :

var demoArray = [
   {name: 'apples', quantity: 2},
   {name: 'bananas', quantity: 0},
   {name: 'cherries', quantity: 5}
];

var result = demoArray.filter( obj => obj.name === 'apples')[0];
console.log(result);
// {name: 'apples', quantity: 2}

Make the script executable by the user "Kev" and then remove the try it running through the command sh kev@server1 /test/foo.sh

Vertically align center with bootstrap 4

Add this class: d-flex align-items-center to the element

Example

If you had this:

<div class="col-3">

change it to this:

<div class="col-3 d-flex align-items-center>

Just wrap floated elements in a <div> and give it this CSS:

.wrapper {

display: table;
margin: auto;

}

There is an important point of arrays that is often not taught or missed in java classes. When arrays are passed to a function, then another pointer is created to the same array ( the same pointer is never passed ). You can manipulate the array using both the pointers, but once you assign the second pointer to a new array in the called method and return back by void to calling function, then the original pointer still remains unchanged.

You can directly run the code here : https://www.compilejava.net/

import java.util.Arrays;

public class HelloWorld
{
    public static void main(String[] args)
    {
        int Main_Array[] = {20,19,18,4,16,15,14,4,12,11,9};
        Demo1.Demo1(Main_Array);
        // THE POINTER Main_Array IS NOT PASSED TO Demo1
        // A DIFFERENT POINTER TO THE SAME LOCATION OF Main_Array IS PASSED TO Demo1

        System.out.println("Main_Array = "+Arrays.toString(Main_Array));
        // outputs : Main_Array = [20, 19, 18, 4, 16, 15, 14, 4, 12, 11, 9]
        // Since Main_Array points to the original location,
        // I cannot access the results of Demo1 , Demo2 when they are void.
        // I can use array clone method in Demo1 to get the required result,
        // but it would be faster if Demo1 returned the result to main
    }
}

public class Demo1
{
    public static void Demo1(int A[])
    {
        int B[] = new int[A.length];
        System.out.println("B = "+Arrays.toString(B)); // output : B = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
        Demo2.Demo2(A,B);
        System.out.println("B = "+Arrays.toString(B)); // output : B = [9999, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
        System.out.println("A = "+Arrays.toString(A)); // output : A = [20, 19, 18, 4, 16, 15, 14, 4, 12, 11, 9]

        A = B;
        // A was pointing to location of Main_Array, now it points to location of B
        // Main_Array pointer still keeps pointing to the original location in void main

        System.out.println("A = "+Arrays.toString(A)); // output : A = [9999, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
        // Hence to access this result from main, I have to return it to main
    }
}
public class Demo2
{
    public static void Demo2(int AAA[],int BBB[])
    {
        BBB[0] = 9999;
        // BBB points to the same location as B in Demo1, so whatever I do
        // with BBB, I am manipulating the location. Since B points to the
        // same location, I can access the results from B
    }
}
