Property hibernate.allow_refresh_detached_entity did the trick for me. But it is a general rule, so it is not very suitable if you want to do it only in some cases. I hope it helps.

Tested on Hibernate 5.4.9

SessionFactoryOptionsBuilder

Here is an option using a for loop by groups rather by rows (like OP did)

for (i in unique(df$cat)) df$num[df$cat == i] <- seq_len(sum(df$cat == i))

You can use:

String.prototype.replaceAll = function(search, replace) {
if (replace === undefined) {
    return this.toString();
}
return this.split(search).join(replace);
}

LESS has guard expressions for mixins, not individual attributes.

So you'd create a mixin like this:

.debug(@debug) when (@debug = true) {
    header {
      background-color: yellow;
      #title {
          background-color: orange;
      }
    }

    article {
      background-color: red;
    }
}

And turn it on or off by calling .debug(true); or .debug(false) (or not calling it at all).

Use android:backgroundTint="" in your EditText xml layout.

For api<21 you can use AppCompatEditText from support library thenapp:backgroundTint=""

Changing a CheckBox appearance to Button will give you difficulty in adjustments. You cannot change its dimensions because its size depends on the size of your text or image.

You can try this: (initialize the count variable first to 1 | int count = 1)

private void settingsBtn_Click(object sender, EventArgs e)
    {
        count++;

        if (count % 2 == 0)
        {
            settingsPanel.Show();
        }
        else
        {
            settingsPanel.Hide();
        }
    }

It's very simple but it works.

Warning: This will work well with buttons that are occasionally used (i.e. settings), the value of count in int/long may be overloaded when used more than it's capacity without closing the app's process. (Check data type ranges: http://msdn.microsoft.com/en-us/library/s3f49ktz.aspx)

The Good News: If you're running an app that is not intended for use 24/7 all-year round, I think this is helpful. Important thing is that when the app's process ended and you run it again, the count will reset to 1.

f = open("Path/To/Your/File.txt", "w")   # 'r' for reading and 'w' for writing
f.write("Hello World from " + f.name)    # Write inside file 
f.close()                                # Close file 

# Method 2shush
with open("Path/To/Your/File.txt", "w") as f:   # Opens file and casts as f 
    f.write("Hello World form " + f.name)       # Writing
# File closed automatically

Neither main() or void main() are standard C. The former is allowed as it has an implicit int return value, making it the same as int main(). The purpose of main's return value is to return an exit status to the operating system.

In standard C, the only valid signatures for main are:

int main(void)

and

int main(int argc, char **argv)

The form you're using: int main() is an old style declaration that indicates main takes an unspecified number of arguments. Don't use it - choose one of those above.

I believe (and I am hardly well-versed in Python) that the main difference is that a tuple is immutable (it can't be changed in place after assignment) and a list is mutable (you can append, change, subtract, etc).

So, I tend to make my tuples things that shouldn't change after assignment and my lists things that can.

Notice you're not dynamically allocating the variable, which pretty much means the data inside str, in your function, will be lost by the end of the function.

You should have:

char * createStr() {

    char char1= 'm';
    char char2= 'y';

    char *str = malloc(3);
    str[0] = char1;
    str[1] = char2;
    str[2] = '\0';

    return str;

}

Then, when you call the function, the type of the variable that will receive the data must match that of the function return. So, you should have:

char *returned_str = createStr();

It worths mentioning that the returned value must be freed to prevent memory leaks.

char *returned_str = createStr();

//doSomething
...

free(returned_str);

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

Check for NULL and empty string values:

select phone
, phone2 
from users 
where phone like '813%' 
and trim(coalesce(phone2, '')) <>''

N.B. I think COALESCE() is SQL standard(-ish), whereas ISNULL() is not.

Of course it is. Here is a sample annotation:

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface TestAnnotation {

    String testText();
}

And a sample annotated method:

class TestClass {

    @TestAnnotation(testText="zyx")
    public void doSomething() {}
}

And a sample method in another class that prints the value of the testText:

Method[] methods = TestClass.class.getMethods();
for (Method m : methods) {
    if (m.isAnnotationPresent(TestAnnotation.class)) {
        TestAnnotation ta = m.getAnnotation(TestAnnotation.class);
        System.out.println(ta.testText());
    }
}

Not much different for field annotations like yours.

Cheerz!

Here's my code (not optimized but a full working example):

<head>
<style>
#divtoshow {position:absolute;display:none;color:white;background-color:black}
#onme {width:150px;height:80px;background-color:yellow;cursor:pointer}
</style>
<script type="text/javascript">
var divName = 'divtoshow'; // div that is to follow the mouse (must be position:absolute)
var offX = 15;          // X offset from mouse position
var offY = 15;          // Y offset from mouse position

function mouseX(evt) {if (!evt) evt = window.event; if (evt.pageX) return evt.pageX; else if (evt.clientX)return evt.clientX + (document.documentElement.scrollLeft ?  document.documentElement.scrollLeft : document.body.scrollLeft); else return 0;}
function mouseY(evt) {if (!evt) evt = window.event; if (evt.pageY) return evt.pageY; else if (evt.clientY)return evt.clientY + (document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop); else return 0;}

function follow(evt) {
    var obj = document.getElementById(divName).style;
    obj.left = (parseInt(mouseX(evt))+offX) + 'px';
    obj.top = (parseInt(mouseY(evt))+offY) + 'px'; 
    }
document.onmousemove = follow;
</script>
</head>
<body>
<div id="divtoshow">test</div>
<br><br>
<div id='onme' onMouseover='document.getElementById(divName).style.display="block"' onMouseout='document.getElementById(divName).style.display="none"'>Mouse over this</div>
</body>

In ubuntu desktop 16.04, I did this:

1. open file: /etc/mysql/mysql.conf.d/mysqld.cnf in an editor of your choice.

2. Look for: sql_mode, it will be somewhere under [mysqld].

3. and set sql_mode to the following:

   NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

4. Save and then restart mysql service by doing:

   sudo service mysql restart

git-credential-osxkeychain stores passwords in the Apple Keychain, as noted above.

By default, gitcredentials only considers the domain name. If you want Git to consider the full path (e.g. if you have multiple GitHub accounts), set the useHttpPath variable to true, as described at http://git-scm.com/docs/gitcredentials.html. Note that changing this setting will ask your credentials again for each URL.

The ngRoute module is no longer part of the core angular.js file. If you are continuing to use $routeProvider then you will now need to include angular-route.js in your HTML:

<script src="angular.js">
<script src="angular-route.js">

API Reference

You also have to add ngRoute as a dependency for your application:

var app = angular.module('MyApp', ['ngRoute', ...]);

If instead you are planning on using angular-ui-router or the like then just remove the $routeProvider dependency from your module .config() and substitute it with the relevant provider of choice (e.g. $stateProvider). You would then use the ui.router dependency:

var app = angular.module('MyApp', ['ui.router', ...]);

The second argument to JSON.stringify() also allows you to specify an array of key names that should be preserved from every object it encounters within your data. This may not work for all use cases, but is a much simpler solution.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify

var obj = {
    a: "foo",
    b: this
}

var json = JSON.stringify(obj, ['a']);
console.log(json);
// {"a":"foo"}

Note: Strangely, the object definition from OP does not throw a circular reference error in the latest Chrome or Firefox. The definition in this answer was modified so that it did throw an error.

Use USE. This will enable you to select the database.

USE photogallery;

12.8.4: USE Syntax

You can also specify the database you want when connecting:

$ mysql -u user -p photogallery

As mentioned previously "there is no CSS selector for selecting a parent of a selected child".

So you either:

• use a CSS hack as described in NGLN's answer
• use javascript - along with jQuery most likely

Here is the example for the javascript/jQuery solution

On the javascript side:

$('#my-id-selector-00').on('mouseover', function(){
  $(this).parent().addClass('is-hover');
}).on('mouseout', function(){
  $(this).parent().removeClass('is-hover');
})

And on the CSS side, you'd have something like this:

.is-hover {
  background-color: red;
}

The SetEnv.cmd script that the "SDK command prompt" shortcut runs checks for cl.exe in various places before setting up entries to add to PATH. So it fails to add anything if a native C compiler is not installed.

To fix that, apply the following patch to <SDK install dir>\Bin\SetEnv.cmd. This will also fix missing paths to other tools located in <SDK install dir>\Bin and subfolders. Of course, you can install the C compiler instead to work around this bug.

Convert the Special characters to apostrophe,

Data  <- gsub("[^0-9A-Za-z///' ]","'" , Data ,ignore.case = TRUE)

Below code it to remove extra ''' apostrophe

Data <- gsub("''","" , Data ,ignore.case = TRUE)

Use gsub(..) function for replacing the special character with apostrophe

HTTP 404 Status

To return a 404 header, just use the :status option for the render method.

def action
  # here the code

  render :status => 404
end

If you want to render the standard 404 page you can extract the feature in a method.

def render_404
  respond_to do |format|
    format.html { render :file => "#{Rails.root}/public/404", :layout => false, :status => :not_found }
    format.xml  { head :not_found }
    format.any  { head :not_found }
  end
end

and call it in your action

def action
  # here the code

  render_404
end

If you want the action to render the error page and stop, simply use a return statement.

def action
  render_404 and return if params[:something].blank?

  # here the code that will never be executed
end

ActiveRecord and HTTP 404

Also remember that Rails rescues some ActiveRecord errors, such as the ActiveRecord::RecordNotFound displaying the 404 error page.

It means you don't need to rescue this action yourself

def show
  user = User.find(params[:id])
end

User.find raises an ActiveRecord::RecordNotFound when the user doesn't exist. This is a very powerful feature. Look at the following code

def show
  user = User.find_by_email(params[:email]) or raise("not found")
  # ...
end

You can simplify it by delegating to Rails the check. Simply use the bang version.

def show
  user = User.find_by_email!(params[:email])
  # ...
end

This is what I use. I do this first query to find the sessions and the users:

select s.sid, s.serial#, p.spid, s.username, s.schemaname
     , s.program, s.terminal, s.osuser
  from v$session s
  join v$process p
    on s.paddr = p.addr
 where s.type != 'BACKGROUND';

This will let me know if there are multiple sessions for the same user. Then I usually check to verify if a session is blocking the database.

SELECT SID, SQL_ID, USERNAME, BLOCKING_SESSION, COMMAND, MODULE, STATUS FROM v$session WHERE BLOCKING_SESSION IS NOT NULL;  

Then I run an ALTER statement to kill a specific session in this format:

ALTER SYSTEM KILL SESSION 'sid,serial#'; 

For example:

ALTER SYSTEM KILL SESSION '314, 2643';

It's throwing this error for me today because I have an app with a min sdk of 28 and am hitting play on an emulator with an SDK version of 23. Usually this is not possible (AS gray's out the play button), but today not so much.

the following code is for making the same y axis limit on two subplots

f ,ax = plt.subplots(1,2,figsize = (30, 13),gridspec_kw={'width_ratios': [5, 1]})
df.plot(ax = ax[0], linewidth = 2.5)
ylim = [lower_limit,upper_limit]
ax[0].set_ylim(ylim)
ax[1].hist(data,normed =1, bins = num_bin, color = 'yellow' ,alpha = 1) 
ax[1].set_ylim(ylim)

just a reminder, plt.hist(range=[low, high]) the histogram auto crops the range if the specified range is larger than the max&min of the data points. So if you want to specify the y-axis range number, i prefer to use set_ylim

Your question is confusing and you really should post some code, but this should work:

onClick="this.disabled=true; this.value='Sending...'; submitForm(); return false;"

I think that when you use this.form.submit() it's doing what happens naturally when you click the submit button. If you want same-page submit, you should look into using AJAX in the submitForm() method (above).

Also, returning false at the end of the onClick attribute value suppresses the default event from firing (in this case submitting the form).

The best thing about C# is that it is very catchy. Easy to pick up, and you'll also have fun doing it.

But .Net framework is a very big library full of wonderful things to discover, and yet again due to the nature of .Net you'll also have fun learning it. It's a coherent, object oriented, well documented library, and C# makes it so simple to work with it that you can simply discover your way through it while coding.

The vast majority of articles, books or resources about .Net and C# simply concentrate on explaining functionality and the framework and far less about how to avoid quirks, workarounds or exceptional cases, like it happens with other languages I don't want to name (*cough C++*) so in the end the experience of learning C# and .Net is very enjoyable from start to finish, and the things you can accomplish using .Net also makes it very rewarding.

You picked a good language to start with, in my opinion, and finally to answer your question, it will take you about:

• 2 to 3 months to learn the basics
• 1 to 2 years to become a versed developer
• 5 years or more to become a expert or, depending on your dedication, a "guru".

But then again, beating the numbers and breaking the limits lies inside human nature. Can you do it faster than this? ;-)

Function convert image to base64 using jquery (you can convert to vanila js). Hope it help to you!

Usage: input is your nameId input has file image

<input type="file" id="asd"/>
<button onclick="proccessData()">Submit</button>

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>

async function converImageToBase64(inputId) {
  let image = $('#'+inputId)[0]['files']

  if (image && image[0]) {
    const reader = new FileReader();

    return new Promise(resolve => {
      reader.onload = ev => {
        resolve(ev.target.result)
      }
      reader.readAsDataURL(image[0])
    })
  }
}

async function proccessData() {
  const image = await converImageToBase64('asd')
  console.log(image)
}

</script>

Example: converImageToBase64('yourFileInputId')

In selec2 site you can see options. There is "disabled" option for api. You can use like :

$('#foo').select2({
    disabled: true
});

The problem is a simple typo. You named your variable 'conc' on line 2 but then referenced 'conn' on line 4.

There is no real limit -- everything is named with a 160-bit name. The size of the file must be representable in a 64 bit number so no real limit there either.

There is a practical limit, though. I have a repository that's ~8GB with >880,000 files and git gc takes a while. The working tree is rather large so operations that inspect the entire working directory take quite a while. This repo is only used for data storage, though, so it's just a bunch of automated tools that handle it. Pulling changes from the repo is much, much faster than rsyncing the same data.

I just learned from a website:

Get-ChildItem *.txt | ForEach-Object { (get-Content $_) | Where-Object {(1) -notcontains $_.ReadCount } | Set-Content -path $_ }

Or you can use the aliases to make it short, like:

gci *.txt | % { (gc $_) | ? { (1) -notcontains $_.ReadCount } | sc -path $_ }

The prerequisite to have WcfTestClient is to have Windows Communication Foundation component installed. If WcfTestClient is missing, install it by modifying Visual Studio:

Control Panel > Apps & Features > Visual Studio (your version)

In Visual Studio Installer, click on Modify, choose Individual components tab and then select (see below screenshot):

? Windows Communication Foundation

Click on Modify and voilà, application will be on your disk.

If you want to use WcfTestClient with no Visual Studio, see answer(s) on: How can the Wcf Test Client be used without Visual Studio?

Your query apparently returned all correct dates, even considering the time.

If you're still not happy with the results, give DATEDIFF a shot and look for negaive/positive results between the two dates.

Make sure your mydate column is a datetime type.

If you don't want to pass the clicked on element to the function through a parameter, then you need to access the event object that is happening, and get the target from that object. This is most easily done if you bind the click event like this:

$('#sendButton').click(function(e){
    var SendButton = $(e.target);
    var TheForm = SendButton.parents('form');
    TheForm.submit();

    return false;
});

In Android studio, Run menu > Run shows OFFLINE ... for the connected device.

Below is the procedure followed to solve it:

1. (Read the below note first) Delete the ~/.android/adbkey (or, rename to ~/.android/adbkey2, this is even better incase you want it back for some reason)
   Note: I happened to do this step, but it didn't solve the problem, after doing all the below steps it worked, so unsure if this step is required.

2. Run locate platform-tools/adb
   Note: use the path that comes from here in below commands

3. Kill adb server:
   sudo ~/Android/Sdk/platform-tools/adb kill-server

4. You will get a Allow accept.. message popup on your device. Accept it. This is important, which solves the problem.

5. Start adb server:
   sudo ~/Android/Sdk/platform-tools/adb start-server

6. In Android studio, do Run menu > Run again
   It will show something like Samsung ... (your phone manufacture name).
   Also installs the apk on device correctly this time without error.

Hope that helps.

For Linux the correct command is:

gcc -o term term.c -lpthread

1. you have to put -lpthread just after the compile command,this command will tell to the compiler to execute program with pthread.h library.
2. gcc -l links with a library file.Link -l with library name without the lib prefix.

Richard, next time, you should add this code under TextView at the layout XML instead.

android:autoLink="all"

This should be like this.

<TextView 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:text="@string/txtCredits"
    android:id="@+id/infoTxtCredits"
    android:autoLink="all"
    android:linksClickable="true">
</TextView>

You don't need to use this code (t2.setMovementMethod(LinkMovementMethod.getInstance());) in order to make the link clickable.

Also, here's the truth: as long as you set the autoLink and the linksClickable, don't forget to add this at String.xml file so that the clickable link will work.

<string name="txtCredits"><a href="http://www.google.com">Google</a></string>

Putting the call to mysql_insert_id() inside a transaction, should do it:

mysql_query('BEGIN');
// Whatever code that does the insert here.
$id = mysql_insert_id();
mysql_query('COMMIT');
// Stuff with $id.

In addition to the other solutions I needed to edit the code signing on the main project and the Target file to get the app building to the device again after an expired provisioning profile.

::Delete the old expired profiles

::Add the new profile with the Organizer

::Clean All Targets

::Get Info -> Code Signing on both the main project and the Target

::Build and Run

Modulus method is the usual method. We can also do this to check if odd or even:

def f(a):
    if (a//2)*2 == a:
        return 'even'
    else:
        return 'odd'

Integer division by 2 followed by multiplication by two.

I did it in my project:

Global Events in application.js:

$(document).bind("ajaxSend", function(){
   $("#loading").show();
 }).bind("ajaxComplete", function(){
   $("#loading").hide();
 });

"loading" is the element to show and hide!

With bootstrap4 you can easily do it like this :-

class="rounded" 

or

class="rounded-circle"

You also could put <span style="font-weight:normal"> around a,b,c and then bold the ul in the CSS.

Example

ul {
    font-weight: bold;
}

<ul><li><span style="font-weight:normal">a</span></li></ul>

As I use Ubuntu, I also needed add this at the top of my Makefile:

SHELL := /bin/bash # Use bash syntax

Then you'd want to do this instead:

print str(int(1.0/3.0*100))+'%'

The .0 denotes them as floats and int() rounds them to integers afterwards again.

Update for FontAwesome 5 ^{Thanks to Aurelien}

You need to change the font-family to Font Awesome 5 Brands OR Font Awesome 5 Free, based on the type of icon you are trying to render. Also, do not forget to declare font-weight: 900;

a:before {
   font-family: "Font Awesome 5 Free";
   content: "\f095";
   display: inline-block;
   padding-right: 3px;
   vertical-align: middle;
   font-weight: 900;
}

Demo

You can read the rest of the answer below to understand how it works and to know some workarounds for spacing between icon and the text.

FontAwesome 4 and below

That's the wrong way to use it. Open the font awesome style sheet, go to the class of the font you want to use say fa-phone, copy the content property under that class with the entity, and use it like:

a:before {
    font-family: FontAwesome;
    content: "\f095";
}

Demo

Just make sure that if you are looking to target a specific a tag, then consider using a class instead to make it more specific like:

a.class_name:before {
    font-family: FontAwesome;
    content: "\f095";
}

Using the way above will stick the icon with the remaining text of yours, so if you want to have a bit of space between the two of them, make it display: inline-block; and use some padding-right:

a:before {
    font-family: FontAwesome;
    content: "\f095";
    display: inline-block;
    padding-right: 3px;
    vertical-align: middle;
}

Extending this answer further, since many might be having a requirement to change an icon on hover, so for that, we can write a separate selector and rules for :hover action:

a:hover:before {
    content: "\f099"; /* Code of the icon you want to change on hover */
}

Demo

Now in the above example, icon nudges because of the different size and you surely don't want that, so you can set a fixed width on the base declaration like

a:before {
    /* Other properties here, look in the above code snippets */
    width: 12px; /* add some desired width here to prevent nudge */
}

Demo

To extract number :

var arrNumber = new Array();
$('input[type=number]').each(function(){
    arrNumber.push($(this).val());
})

To extract text:

var arrText= new Array();
$('input[type=text]').each(function(){
    arrText.push($(this).val());
})

Edit : .map implementation

var arrText= $('input[type=text]').map(function(){
    return this.value;
}).get();

Extension attributes are added by Exchange. According to this Technet article something like this should work:

Set-Mailbox -Identity "anyUser" -ExtensionCustomAttribute4 @{Remove="myString"}

You can also get this error if you try to include a jar which was compiled with jdk 1.7 instead of 1.6.

In my case, I figured this out by trying to package my app with the Ant scripts provided by the SDK, instead of ADT, and I noticed these errors, which ADT did not show me:

  [dex] Pre-Dexing libjingle_peerconnection.jar -> libjingle_peerconnection-2f82c9bf868a6c58eaf2c3b2fe6a09f3.jar

   [dx] ...while parsing org/webrtc/StatsReport$Value.class
   [dx] ...while processing org/webrtc/StatsReport$Value.class

I recompiled my jar with jdk 1.6 and the error was fixed.

Actually I wanted same alike thing, To get one year backward date, for a given date! :-)

With the hint of above answer from @mohammad mohsenipur I got to the following link, via his given link!

Luckily, there is a method same as date_add method, named date_sub method! :-) I do the following to get done what I wanted!

$date = date_create('2000-01-01');
date_sub($date, date_interval_create_from_date_string('1 years'));
echo date_format($date, 'Y-m-d');

Hopes this answer will help somebody too! :-)

Good luck guys!

In my case the issue was not resolved because i did not restart my system. Please make sure you do restart your system.

There is the possibility of making something really more cool!

I would recommend reviewing this page on How to Write Go Code

It documents both how to structure your project in a go build friendly way, and also how to write tests. Tests do not need to be a cmd using the main package. They can simply be TestX named functions as part of each package, and then go test will discover them.

The structure suggested in that link in your question is a bit outdated, now with the release of Go 1. You no longer would need to place a pkg directory under src. The only 3 spec-related directories are the 3 in the root of your GOPATH: bin, pkg, src . Underneath src, you can simply place your project mypack, and underneath that is all of your .go files including the mypack_test.go

go build will then build into the root level pkg and bin.

So your GOPATH might look like this:

~/projects/
    bin/
    pkg/
    src/
      mypack/
        foo.go
        bar.go
        mypack_test.go

export GOPATH=$HOME/projects

$ go build mypack
$ go test mypack

Update: as of >= Go 1.11, the Module system is now a standard part of the tooling and the GOPATH concept is close to becoming obsolete.

WCF = Windows Communication Foundation is used to build service-oriented applications. WPF = Windows Presentation Foundation is used to write platform-independent applications.

A possibility is to declare the variable at the index.html because it is really global. It can be done adding a javascript method to return the value of the variable, and it will be READ ONLY.

An example of this solution can be found at this answer: https://stackoverflow.com/a/62485644/1178478

If the script name has spaces in it, a more robust way is to use "$0" or "$(basename "$0")" - or on MacOS: "$(basename \"$0\")". This prevents the name from getting mangled or interpreted in any way. In general, it is good practice to always double-quote variable names in the shell.

I would suggest defining your own package based on the following tex code; this gives you complete freedom. http://ubuntuforums.org/archive/index.php/t-331602.html

You might find a use for the methods method which returns an array of methods for an object. It's not the same as print_r, but still useful at times.

Put in your js file

                var url = window.location.href;
                console.log(url);
                console.log(~url.indexOf("#product-consulation"));
                if (~url.indexOf("#product-consulation")) {
                    console.log('YES');
                    // $('html, body').animate({
                    //     scrollTop: $('#header').offset().top - 80
                    // }, 1000);
                } else {
                    console.log('NOPE');
                }

You should be able to use Windows "UNC" paths with robocopy. For example:

robocopy \\myServer\myFolder\myFile.txt \\myOtherServer\myOtherFolder

Robocopy has the ability to recover from certain types of network hiccups automatically.

First shift the column:

df['gdp'] = df['gdp'].shift(-1)

Second remove the last row which contains an NaN Cell:

df = df[:-1]

Third reset the index:

df = df.reset_index(drop=True)

We had the same problem and you have to use

git fetch

git push origin branch_name

git branch -r

Hope this help someone facing the same problem

With jQuery its just: $(this).blur();

Calling toDate will create a copy (the documentation is down-right wrong about it not being a copy), of the underlying JS Date object. JS Date object is stored in UTC and will always print to eastern time. Without getting into whether .utc() modifies the underlying object that moment wraps use the code below.

You don't need moment for this.

new Date().getTime()

This works, because JS Date at its core is in UTC from the Unix Epoch. It's extraordinarily confusing and I believe a big flaw in the interface to mix local and UTC times like this with no descriptions in the methods.

You can put up all your JS like this, so it doesn't execute before your HTML is ready

$(document).ready(function() {
   // some code here
 });

Remember this is jQuery so include it in the head section. Also see Why you should use jQuery and not onload

Warning: [function] expects parameter 1 to be resource, boolean given

(A more general variation of Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given)

Resources are a type in PHP (like strings, integers or objects). A resource is an opaque blob with no inherently meaningful value of its own. A resource is specific to and defined by a certain set of PHP functions or extension. For instance, the Mysql extension defines two resource types:

There are two resource types used in the MySQL module. The first one is the link identifier for a database connection, the second a resource which holds the result of a query.

The cURL extension defines another two resource types:

... a cURL handle and a cURL multi handle.

When var_dumped, the values look like this:

$resource = curl_init();
var_dump($resource);

resource(1) of type (curl)

That's all most resources are, a numeric identifier ((1)) of a certain type ((curl)).

You carry these resources around and pass them to different functions for which such a resource means something. Typically these functions allocate certain data in the background and a resource is just a reference which they use to keep track of this data internally.

The "... expects parameter 1 to be resource, boolean given" error is typically the result of an unchecked operation that was supposed to create a resource, but returned false instead. For instance, the fopen function has this description:

Return Values

Returns a file pointer resource on success, or FALSE on error.

So in this code, $fp will either be a resource(x) of type (stream) or false:

$fp = fopen(...);

If you do not check whether the fopen operation succeed or failed and hence whether $fp is a valid resource or false and pass $fp to another function which expects a resource, you may get the above error:

$fp   = fopen(...);
$data = fread($fp, 1024);

Warning: fread() expects parameter 1 to be resource, boolean given

You always need to error check the return value of functions which are trying to allocate a resource and may fail:

$fp = fopen(...);

if (!$fp) {
    trigger_error('Failed to allocate resource');
    exit;
}

$data = fread($fp, 1024);

Related Errors:

• Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given

d,e,f
g,h,i
j,k,l"""

print(data.split())       # ['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']

str.split, by default, splits by all the whitespace characters. If the actual string has any other whitespace characters, you might want to use

print(data.split("\n"))   # ['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']

Or as @Ashwini Chaudhary suggested in the comments, you can use

print(data.splitlines())

    //founded and i starts on correct and i+k is the first char after
    end = origin.substring(i+k,originLen);
    if(i == 0)
        return end;
    else{
        start = origin.substring(0,i) 
        return (start + end);

To check if a string variable contains a valid email address, the easiest way is to test it against a regular expression. There is a good discussion of various regex's and their trade-offs at regular-expressions.info.

Here is a relatively simple one that leans on the side of allowing some invalid addresses through: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$

How you can use regular expressions depends on the version of iOS you are using.

iOS 4.x and Later

You can use NSRegularExpression, which allows you to compile and test against a regular expression directly.

iOS 3.x

Does not include the NSRegularExpression class, but does include NSPredicate, which can match against regular expressions.

NSString *emailRegex = ...;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
BOOL isValid = [emailTest evaluateWithObject:checkString];

Read a full article about this approach at cocoawithlove.com.

iOS 2.x

Does not include any regular expression matching in the Cocoa libraries. However, you can easily include RegexKit Lite in your project, which gives you access to the C-level regex APIs included on iOS 2.0.

I answered this question and no you do not need an arraylist or any other thing this was an assignment and I completed it so yes arrays can increase in size. Here is the link How to use Java Dynamic Array and here is the link for my question which i answered Java Dynamic arrays

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 }
);

Take a look at Enumerable#each_slice:

foo.each_slice(3).to_a
#=> [["1", "2", "3"], ["4", "5", "6"], ["7", "8", "9"], ["10"]]

Try this

Check if table have there , and drop the table , then create

using (SqlCommand command = new SqlCommand("IF EXISTS (
SELECT *
FROM sys.tables
WHERE name LIKE '#Customer%')
DROP TABLE #Customer CREATE TABLE Customer(First_Name char(50),Last_Name char(50),Address char(50),City char(50),Country char(25),Birth_Date datetime);", con))

Jeff has a post about it, otherwise I found some useful documents on Apple's website, in Cocoa tutorials (this one for example).

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

$("a[href*=ABC]").addClass('selected');

This code also helps in, "To Detect Numbers in Given String" when numbers found it stops its execution.

function hasDigitFind(_str_) {
  this._code_ = 10;  /*When empty string found*/
  var _strArray = [];

  if (_str_ !== '' || _str_ !== undefined || _str_ !== null) {
    _strArray = _str_.split('');
    for(var i = 0; i < _strArray.length; i++) {
      if(!isNaN(parseInt(_strArray[i]))) {
        this._code_ = -1;
        break;
      } else {
        this._code_ = 1;
      }
    }

  }
  return this._code_;
}

It's also cleaner to use @JoinTable when an Entity could be the child in several parent/child relationships with different types of parents. To follow up with Behrang's example, imagine a Task can be the child of Project, Person, Department, Study, and Process.

Should the task table have 5 nullable foreign key fields? I think not...

If you have installed Apache with OpenSSL navigate to bin directory. In my case D:\apache\bin.

*This will create self-signed certificate that you can use for development purposes

Again if you have Apache installed in the httpd.conf stick these:

  <IfModule ssl_module>
    SSLEngine on
    SSLCertificateFile "D:/apache/conf/server.crt"
    SSLCertificateKeyFile "D:/apache/conf/server.key"
  </IfModule>

First, note that the function parameter named i and the variable named i in main() are two different variables. I think that doesn't matter that much to the present discussion, but it's important to know.

Second, you use the postincrement operator in fun(). That means the result of the expression is the value before i is incremented; the final value 11 of i is simply discarded, and the function returns 10. The variable i back in main, being a different variable, is assigned the value 10, which you then decrement to get 9.

This function returns the approximate screen size in inches.

public double getScreenSize()
{
        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        int width=dm.widthPixels;
        int height=dm.heightPixels;
        int dens=dm.densityDpi;
        double wi=(double)width/(double)dens;
        double hi=(double)height/(double)dens;
        double x = Math.pow(wi,2);
        double y = Math.pow(hi,2);
        double screenInches = Math.sqrt(x+y);
        return screenInches;
}

java -cp CLASSPATH is necesssary if you wish to specify all code in the classpath. This is useful for debugging code.

The jarred executable format: java -jar JarFile can be used if you wish to start the app with a single short command. You can specify additional dependent jar files in your MANIFEST using space separated jars in a Class-Path entry, e.g.:

Class-Path: mysql.jar infobus.jar acme/beans.jar

Both are comparable in terms of performance.

In Modern OpenGL(OpenGL 3.2 and higher), you could use a Geometry Shader for this :

#version 330

layout (triangles) in;
layout (line_strip /*for lines, use "points" for points*/, max_vertices=3) out;

in vec2 texcoords_pass[]; //Texcoords from Vertex Shader
in vec3 normals_pass[]; //Normals from Vertex Shader

out vec3 normals; //Normals for Fragment Shader
out vec2 texcoords; //Texcoords for Fragment Shader

void main(void)
{
    int i;
    for (i = 0; i < gl_in.length(); i++)
    {
        texcoords=texcoords_pass[i]; //Pass through
        normals=normals_pass[i]; //Pass through
        gl_Position = gl_in[i].gl_Position; //Pass through
        EmitVertex();
    }
    EndPrimitive();
}

Notices :

• for points, change layout (line_strip, max_vertices=3) out; to layout (points, max_vertices=3) out;
• Read more about Geometry Shaders

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

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

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

There's a difference between additive colors (http://en.wikipedia.org/wiki/Additive_color) and subtractive colors (http://en.wikipedia.org/wiki/Subtractive_color).

With additive colors, the more you add, the brighter the colors become. This is because they are emitting light. This is why the day light is (more or less) white, since the Sun is emitting in almost all the visible wavelength spectrum.

On the other hand, with subtractive colors the more colors you mix, the darker the resulting color. This is because they are reflecting light. This is also why the black colors get hotter quickly, because it absorbs (almost) all light energy and reflects (almost) none.

Specifically to your question, it depends what medium you are working on. Traditionally, additive colors (RGB) are used because the canon for computer graphics was the computer monitor, and since it's emitting light, it makes sense to use the same structure for the graphic card (the colors are shown without conversions). However, if you are used to graphic arts and press, subtractive color model is used (CMYK). In programs such as Photoshop, you can choose to work in CMYK space although it doesn't matter what color model you use: the primary colors of one group are the secondary colors of the second one and viceversa.

P.D.: my father worked at graphic arts, this is why i know this... :-P

Short answer: While it's technically possible to send 100k e-mails each week yourself, the simplest, easiest and cheapest solution is to outsource this to one of the companies that specialize in it (I did say "cheapest": there's no limit to the amount of development time (and therefore money) that you can sink into this when trying to DIY).

Long answer: If you decide that you absolutely want to do this yourself, prepare for a world of hurt (after all, this is e-mail/e-fail we're talking about). You'll need:

• e-mail content that is not spam (otherwise you'll run into additional major roadblocks on every step, even legal repercussions)
• in addition, your content should be easy to distinguish from spam - that may be a bit hard to do in some cases (I heard that a certain pharmaceutical company had to all but abandon e-mail, as their brand names are quite common in spams)
• a configurable SMTP server of your own, one which won't buckle when you dump 100k e-mails onto it (your ISP's upstream server won't be sufficient here and you'll make the ISP violently unhappy; we used two dedicated boxes)
• some mail wrapper (e.g. PhpMailer if PHP's your poison of choice; using PHP's mail() is horrible enough by itself)
• your own sender function to run in a loop, create the mails and pass them to the wrapper (note that you may run into PHP's memory limits if your app has a memory leak; you may need to recycle the sending process periodically, or even better, decouple the "creating e-mails" and "sending e-mails" altogether)

Surprisingly, that was the easy part. The hard part is actually sending it:

• some servers will ban you when you send too many mails close together, so you need to shuffle and watch your queue (e.g. send one mail to [email protected], then three to other domains, only then another to [email protected])
• you need to have correct PTR, SPF, DKIM records
• handling remote server timeouts, misconfigured DNS records and other network pleasantries
• handling invalid e-mails (and no, regex is the wrong tool for that)
• handling unsubscriptions (many legitimate newsletters have been reclassified as spam due to many frustrated users who couldn't unsubscribe in one step and instead chose to "mark as spam" - the spam filters do learn, esp. with large e-mail providers)
• handling bounces and rejects ("no such mailbox [email protected]","mailbox [email protected] full")
• handling blacklisting and removal from blacklists (Sure, you're not sending spam. Some recipients won't be so sure - with such large list, it will happen sometimes, no matter what precautions you take. Some people (e.g. your not-so-scrupulous competitors) might even go as far to falsely report your mailings as spam - it does happen. On average, it takes weeks to get yourself removed from a blacklist.)

And to top it off, you'll have to manage the legal part of it (various federal, state, and local laws; and even different tangles of laws once you send outside the U.S. (note: you have no way of finding if [email protected] lives in Southwest Elbonia, the country with world's most draconian antispam laws)).

I'm pretty sure I missed a few heads of this hydra - are you still sure you want to do this yourself? If so, there'll be another wave, this time merely the annoying problems inherent in sending an e-mail. (You see, SMTP is a store-and-forward protocol, which means that your e-mail will be shuffled across many SMTP servers around the Internet, in the hope that the next one is a bit closer to the final recipient. Basically, the e-mail is sent to an SMTP server, which puts it into its forward queue; when time comes, it will forward it further to a different SMTP server, until it reaches the SMTP server for the given domain. This forward could happen immediately, or in a few minutes, or hours, or days, or never.) Thus, you'll see the following issues - most of which could happen en route as well as at the destination:

• the remote SMTP servers don't want to talk to your SMTP server
• your mails are getting marked as spam (<blink> is not your friend here, nor is <font color=...>)
• your mails are delivered days, even weeks late (contrary to popular opinion, SMTP is designed to make a best effort to deliver the message sometime in the future - not to deliver it now)
• your mails are not delivered at all (already sent from e-mail server on hop #4, not sent yet from server on hop #5, the server that currently holds the message crashes, data is lost)
• your mails are mangled by some braindead server en route (this one is somewhat solvable with base64 encoding, but then the size goes up and the e-mail looks more suspicious)
• your mails are delivered and the recipients seem not to want them ("I'm sure I didn't sign up for this, I remember exactly what I did a year ago" (of course you do, sir))
• users with various versions of Microsoft Outlook and its special handling of Internet mail
• wizard's apprentice mode (a self-reinforcing positive feedback loop - in other words, automated e-mails as replies to automated e-mails as replies to...; you really don't want to be the one to set this off, as you'd anger half the internet at yourself)

and it'll be your job to troubleshoot and solve this (hint: you can't, mostly). The people who run a legit mass-mailing businesses know that in the end you can't solve it, and that they can't solve it either - and they have the reasons well researched, documented and outlined (maybe even as a Powerpoint presentation - complete with sounds and cool transitions - that your bosses can understand), as they've had to explain this a million times before. Plus, for the problems that are actually solvable, they know very well how to solve them.

If, after all this, you are not discouraged and still want to do this, go right ahead: it's even possible that you'll find a better way to do this. Just know that the road ahead won't be easy - sending e-mail is trivial, getting it delivered is hard.

Use window.open():

var win = window.open('http://stackoverflow.com/', '_blank');
if (win) {
    //Browser has allowed it to be opened
    win.focus();
} else {
    //Browser has blocked it
    alert('Please allow popups for this website');
}

Depending on the browsers implementation this will work

There is nothing you can do to make it open in a window rather than a tab.

It is indeed possible to change a div elements' width in jQuery:

$("#div").css("width", "300px");

However, what you're describing can be better and more effectively achieved in CSS by setting a width as a percentage:

#div {
    width: 75%;
    /* You can also specify min/max widths */
    min-width: 300px;
    max-width: 960px;
}

This div will then always be 75% the width of the screen, unless the screen width means the div will be smaller than 300px, or bigger than 960px.

Declare your manifest header like this

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.yourpackage"
    xmlns:tools="http://schemas.android.com/tools">

Then you can add to your application tag the following attribute:

<application
    tools:replace="icon, label" ../>

For example I need to replace icon and label. Good luck!

If you don't really need the button element, just move the classes to a regular link:

<div class="btn-group">
    <a href="/save/1" class="btn btn-primary active">
        <i class="glyphicon glyphicon-floppy-disk" aria-hidden="true"></i> Save
    </a>
    <a href="/cancel/1" class="btn btn-default">Cancel</a>
</div>

Conversely, you can also change a button to appear like a link:

<button type="button" class="btn btn-link">Link</button>

This is a way to see if any XML-files exists in that folder, yes.

To check for specific files use File.Exists(path), which will return a boolean indicating wheter the file at path exists.

I was also facing the same error. The reason for this is that there is no smtp server on your environment. For creating a fake smtp server I used this fake-smtp.jar file for creating a virtual server and listening to all the requests. If you are facing the same error, I recommend you to use this jar and run it after extracting and then try to run your application.

Download latest version of fake smtp

the plus works just fine, i personally prefer using the concat function.

var s = string.Concat(string 1, string 2, string, 3, etc)

I would suggest to use Autoresizing Mask in your applications according to your UI interface, it saves a lot of trouble and is better than making different UI for iPhone 4 and 5 screens.

.success { background-color: #cffccc; overflow: scroll; min-width: 100%; }

You can try scroll or auto.

I hope this complete example will help you.

This is the TaxiInfo class which holds information about a taxi ride:

namespace Taxi.Models
{
    public class TaxiInfo
    {
        public String Driver { get; set; }
        public Double Fare { get; set; }
        public Double Distance { get; set; }
        public String StartLocation { get; set; }
        public String EndLocation { get; set; }
    }
}

We also have a convenience model which holds a List of TaxiInfo(s):

namespace Taxi.Models
{
    public class TaxiInfoSet
    {
        public List<TaxiInfo> TaxiInfoList { get; set; }

        public TaxiInfoSet(params TaxiInfo[] TaxiInfos)
        {
            TaxiInfoList = new List<TaxiInfo>();

            foreach(var TaxiInfo in TaxiInfos)
            {
                TaxiInfoList.Add(TaxiInfo);
            }
        }
    }
}

Now in the home controller we have the default Index action which for this example makes two taxi drivers and adds them to the list contained in a TaxiInfo:

public ActionResult Index()
{
    var taxi1 = new TaxiInfo() { Fare = 20.2, Distance = 15, Driver = "Billy", StartLocation = "Perth", EndLocation = "Brisbane" };
    var taxi2 = new TaxiInfo() { Fare = 2339.2, Distance = 1500, Driver = "Smith", StartLocation = "Perth", EndLocation = "America" };

    return View(new TaxiInfoSet(taxi1,taxi2));
}

The code for the view is as follows:

@model Taxi.Models.TaxiInfoSet
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

@foreach(var TaxiInfo in Model.TaxiInfoList){
    <form>
        <h1>Cost: [email protected]</h1>
        <h2>Distance: @(TaxiInfo.Distance) km</h2>
        <p>
            Our diver, @TaxiInfo.Driver will take you from @TaxiInfo.StartLocation to @TaxiInfo.EndLocation
        </p>
        @Html.ActionLink("Home","Booking",TaxiInfo)
    </form>
}

The ActionLink is responsible for the re-directing to the booking action of the Home controller (and passing in the appropriate TaxiInfo object) which is defiend as follows:

    public ActionResult Booking(TaxiInfo Taxi)
    {
        return View(Taxi);
    }

This returns a the following view:

@model Taxi.Models.TaxiInfo

@{
    ViewBag.Title = "Booking";
}

<h2>Booking For</h2>
<h1>@Model.Driver, going from @Model.StartLocation to @Model.EndLocation (a total of @Model.Distance km) for [email protected]</h1>

Before data bind change gridview databinding method, assign GridView.EditIndex to -1. It solved the same issue for me :

 gvTypes.DataBind();

gvTypes is my GridView ID.

If you're using .NET Framework 4.5 or above, there is a now a MimeMapping.GetMimeMapping(filename) method that will return a string with the correct Mime mapping for the passed filename. Note that this uses the file extension, not data in the file itself.

Documentation is at http://msdn.microsoft.com/en-us/library/system.web.mimemapping.getmimemapping

string sub = input.Substring(input.Length - 5);

In java we can read input values in 6 ways:

1. Scanner Class
2. BufferedReader
3. Console class
4. Command line
5. AWT, String, GUI
6. System properties

1. Scanner class: present in java.util.*; package and it has many methods, based your input types you can utilize those methods. a. nextInt() b. nextLong() c. nextFloat() d. nextDouble() e. next() f. nextLine(); etc...

import java.util.Scanner;
public class MyClass {
    public static void main(String args[]) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter a :");
        int a = sc.nextInt();
        System.out.println("Enter b :");
        int b = sc.nextInt();
        
        int c = a + b;
        System.out.println("Result: "+c);
    }
}

2. BufferedReader class: present in java.io.*; package & it has many method, to read the value from the keyboard use "readLine()" : this method reading one line at a time.

import java.io.BufferedReader;
import java.io.*;
public class MyClass {
    public static void main(String args[]) throws IOException {
       BufferedReader br = new BufferedReader(new BufferedReader(new InputStreamReader(System.in)));
        System.out.println("Enter a :");
        int a = Integer.parseInt(br.readLine());
        System.out.println("Enter b :");
        int b = Integer.parseInt(br.readLine());
        
        int c = a + b;
        System.out.println("Result: "+c);
    }
}

setting up a ftp or even an SFTP connection or chmod 777 are bad ways to go for anything other than a local environment. Opening even an SFTP method introduces more security risks that are not needed.

what is needed is a writeable permission to /wp-content/uploads & /wp-content/plugins/ by the owner of those directories. (linux ls -la will show you ownership).

Default apache user that runs is www-data.

chmod 777 allows any user on the machine to edit those file, not just the apache/php thread user.

SFTP if you are not already using it, will introduce another point of possible failure from an external source. Whereas you only need access by the local user running the apache/php process to complete the objective.

Didn't see anyone making these points, so I thought I would offer this info to help with our constant WP security issues online.

I found this simple and usefull. Works even if first day of week is Sunday or Monday.

DECLARE @BaseDate AS Date

SET @BaseDate = GETDATE()

DECLARE @FisrtDOW AS Date

SELECT @FirstDOW = DATEADD(d,DATEPART(WEEKDAY,@BaseDate) *-1 + 1, @BaseDate)

Put this at the top of the other files where you want to access the class:

using CLIck10.App_Code;

OR access the class from other files like this:

CLIck10.App_Code.Glob

Not sure if that's your issue or not but if you were new to C# then this is an easy one to get tripped up on.

Update: I recently found that if I add an App_Code folder to a project, then I must close/reopen Visual Studio for it to properly recognize this "special" folder.

We can directly subtract dates to get difference in Days.

    SET SERVEROUTPUT ON ;
    DECLARE
        V_VAR NUMBER;
    BEGIN
         V_VAR:=TO_DATE('2000-01-02', 'YYYY-MM-DD') - TO_DATE('2000-01-01', 'YYYY-MM-DD') ;
         DBMS_OUTPUT.PUT_LINE(V_VAR);
    END;

The data.table package also has unique and duplicated methods of it's own with some additional features.

Both the unique.data.table and the duplicated.data.table methods have an additional by argument which allows you to pass a character or integer vector of column names or their locations respectively

library(data.table)
DT <- data.table(id = c(1,1,1,2,2,2),
                 val = c(10,20,30,10,20,30))

unique(DT, by = "id")
#    id val
# 1:  1  10
# 2:  2  10

duplicated(DT, by = "id")
# [1] FALSE  TRUE  TRUE FALSE  TRUE  TRUE

Another important feature of these methods is a huge performance gain for larger data sets

library(microbenchmark)
library(data.table)
set.seed(123)
DF <- as.data.frame(matrix(sample(1e8, 1e5, replace = TRUE), ncol = 10))
DT <- copy(DF)
setDT(DT)

microbenchmark(unique(DF), unique(DT))

I've created a github repo summing up this article basically: https://medium.com/opinionated-angularjs/techniques-for-authentication-in-angularjs-applications-7bbf0346acec

ng-login Github repo

Plunker

I'll try to explain as good as possible, hope I help some of you out there:

(1) app.js: Creation of authentication constants on app definition

var loginApp = angular.module('loginApp', ['ui.router', 'ui.bootstrap'])
/*Constants regarding user login defined here*/
.constant('USER_ROLES', {
    all : '*',
    admin : 'admin',
    editor : 'editor',
    guest : 'guest'
}).constant('AUTH_EVENTS', {
    loginSuccess : 'auth-login-success',
    loginFailed : 'auth-login-failed',
    logoutSuccess : 'auth-logout-success',
    sessionTimeout : 'auth-session-timeout',
    notAuthenticated : 'auth-not-authenticated',
    notAuthorized : 'auth-not-authorized'
})

(2) Auth Service: All following functions are implemented in auth.js service. The $http service is used to communicate with the server for the authentication procedures. Also contains functions on authorization, that is if the user is allowed to perform a certain action.

angular.module('loginApp')
.factory('Auth', [ '$http', '$rootScope', '$window', 'Session', 'AUTH_EVENTS', 
function($http, $rootScope, $window, Session, AUTH_EVENTS) {

authService.login() = [...]
authService.isAuthenticated() = [...]
authService.isAuthorized() = [...]
authService.logout() = [...]

return authService;
} ]);

(3) Session: A singleton to keep user data. The implementation here depends on you.

angular.module('loginApp').service('Session', function($rootScope, USER_ROLES) {

    this.create = function(user) {
        this.user = user;
        this.userRole = user.userRole;
    };
    this.destroy = function() {
        this.user = null;
        this.userRole = null;
    };
    return this;
});

(4) Parent controller: Consider this as the "main" function of your application, all controllers inherit from this controller, and it's the backbone of the authentication of this app.

<body ng-controller="ParentController">
[...]
</body>

(5) Access control: To deny access on certain routes 2 steps have to be implemented:

a) Add data of the roles allowed to access each route, on ui router's $stateProvider service as can be seen below (same can work for ngRoute).

.config(function ($stateProvider, USER_ROLES) {
  $stateProvider.state('dashboard', {
    url: '/dashboard',
    templateUrl: 'dashboard/index.html',
    data: {
      authorizedRoles: [USER_ROLES.admin, USER_ROLES.editor]
    }
  });
})

b) On $rootScope.$on('$stateChangeStart') add the function to prevent state change if the user is not authorized.

$rootScope.$on('$stateChangeStart', function (event, next) {
    var authorizedRoles = next.data.authorizedRoles;
    if (!Auth.isAuthorized(authorizedRoles)) {
      event.preventDefault();
      if (Auth.isAuthenticated()) {
        // user is not allowed
        $rootScope.$broadcast(AUTH_EVENTS.notAuthorized);
      } else {
        // user is not logged in
        $rootScope.$broadcast(AUTH_EVENTS.notAuthenticated);
      }
    }
});

(6) Auth interceptor: This is implemented, but can't be checked on the scope of this code. After each $http request, this interceptor checks the status code, if one of the below is returned, then it broadcasts an event to force the user to log-in again.

angular.module('loginApp')
.factory('AuthInterceptor', [ '$rootScope', '$q', 'Session', 'AUTH_EVENTS',
function($rootScope, $q, Session, AUTH_EVENTS) {
    return {
        responseError : function(response) {
            $rootScope.$broadcast({
                401 : AUTH_EVENTS.notAuthenticated,
                403 : AUTH_EVENTS.notAuthorized,
                419 : AUTH_EVENTS.sessionTimeout,
                440 : AUTH_EVENTS.sessionTimeout
            }[response.status], response);
            return $q.reject(response);
        }
    };
} ]);

P.S. A bug with the form data autofill as stated on the 1st article can be easily avoided by adding the directive that is included in directives.js.

P.S.2 This code can be easily tweaked by the user, to allow different routes to be seen, or display content that was not meant to be displayed. The logic MUST be implemented server-side, this is just a way to show things properly on your ng-app.

well i would suggest you to check condition in your controller with a function returning true or false .

<div class="week-wrap" ng-class="{today: getTodayForHighLight(todayDate, day.date)}">{{day.date}}</div>

and in your controller check the condition

$scope.getTodayForHighLight = function(today, date){
    return (today == date);
}

The complete solution:

    function bindFullscreen(video) {
            $(video).unbind('click').click(toggleFullScreen);
    }

    function toggleFullScreen() {
            if (!document.fullscreenElement &&    // alternative standard method
                    !document.mozFullScreenElement && !document.webkitFullscreenElement && !document.msFullscreenElement ) {  // current working methods
                    if (document.documentElement.requestFullscreen) {
                            document.documentElement.requestFullscreen();
                    } else if (document.documentElement.msRequestFullscreen) {
                            document.documentElement.msRequestFullscreen();
                    } else if (document.documentElement.mozRequestFullScreen) {
                            document.documentElement.mozRequestFullScreen();
                    } else if (document.documentElement.webkitRequestFullscreen) {
                            document.documentElement.webkitRequestFullscreen(Element.ALLOW_KEYBOARD_INPUT);
                    }
            } 
            else {
                    if (document.exitFullscreen) {
                            document.exitFullscreen();
                    } else if (document.msExitFullscreen) {
                            document.msExitFullscreen();
                    } else if (document.mozCancelFullScreen) {
                            document.mozCancelFullScreen();
                    } else if (document.webkitExitFullscreen) {
                            document.webkitExitFullscreen();
                    }
            }

You should try sending with built-in mail composer, and if that fails, try with share:

func contactUs() {

    let email = "[email protected]" // insert your email here
    let subject = "your subject goes here"
    let bodyText = "your body text goes here"

    // https://developer.apple.com/documentation/messageui/mfmailcomposeviewcontroller
    if MFMailComposeViewController.canSendMail() {

        let mailComposerVC = MFMailComposeViewController()
        mailComposerVC.mailComposeDelegate = self as? MFMailComposeViewControllerDelegate

        mailComposerVC.setToRecipients([email])
        mailComposerVC.setSubject(subject)
        mailComposerVC.setMessageBody(bodyText, isHTML: false)

        self.present(mailComposerVC, animated: true, completion: nil)

    } else {
        print("Device not configured to send emails, trying with share ...")

        let coded = "mailto:\(email)?subject=\(subject)&body=\(bodyText)".addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
        if let emailURL = URL(string: coded!) {
            if #available(iOS 10.0, *) {
                if UIApplication.shared.canOpenURL(emailURL) {
                    UIApplication.shared.open(emailURL, options: [:], completionHandler: { (result) in
                        if !result {
                            print("Unable to send email.")
                        }
                    })
                }
            }
            else {
                UIApplication.shared.openURL(emailURL as URL)
            }
        }
    }
}

You can use numpy.recfromcsv(filename): the types of each column will be automatically determined (as if you use np.genfromtxt() with dtype=None), and by default delimiter=",". It's basically a shortcut for np.genfromtxt(filename, delimiter=",", dtype=None) that Pierre GM pointed at in his answer.

There is no platform-neutral way of doing this. In the 1.6 release of Java, a "Desktop" class was added the allows portable ways of browsing, editing, mailing, opening, and printing URI's. It is possible this class may someday be extended to support processes, but I doubt it.

If you are only curious in Java processes, you can use the java.lang.management api for getting thread/memory information on the JVM.

Would like to outline a brief semantic parallel to an already correct answer.

In 'simple' terms, a recursive CTE can be semantically defined as the following parts:

1: The CTE query. Also known as ANCHOR.

2: The recursive CTE query on the CTE in (1) with UNION ALL (or UNION or EXCEPT or INTERSECT) so the ultimate result is accordingly returned.

3: The corner/termination condition. Which is by default when there are no more rows/tuples returned by the recursive query.

A short example that will make the picture clear:

;WITH SupplierChain_CTE(supplier_id, supplier_name, supplies_to, level)
AS
(
SELECT S.supplier_id, S.supplier_name, S.supplies_to, 0 as level
FROM Supplier S
WHERE supplies_to = -1    -- Return the roots where a supplier supplies to no other supplier directly

UNION ALL

-- The recursive CTE query on the SupplierChain_CTE
SELECT S.supplier_id, S.supplier_name, S.supplies_to, level + 1
FROM Supplier S
INNER JOIN SupplierChain_CTE SC
ON S.supplies_to = SC.supplier_id
)
-- Use the CTE to get all suppliers in a supply chain with levels
SELECT * FROM SupplierChain_CTE

Explanation: The first CTE query returns the base suppliers (like leaves) who do not supply to any other supplier directly (-1)

The recursive query in the first iteration gets all the suppliers who supply to the suppliers returned by the ANCHOR. This process continues till the condition returns tuples.

UNION ALL returns all the tuples over the total recursive calls.

Another good example can be found here.

PS: For a recursive CTE to work, the relations must have a hierarchical (recursive) condition to work on. Ex: elementId = elementParentId.. you get the point.

If the directory doesn't exist you need to create it. Java won't create it by itself since the File class is just a link to an entity that can also not exist at all.

As you stated the error is that the file cannot be created. If you read the documentation of PrintWriter constructor you can see

FileNotFoundException - If the given string does not denote an existing, writable regular file and a new regular file of that name cannot be created, or if some other error occurs while opening or creating the file

You should try creating a path for the folder it contains before:

File file = new File("C:/Users/Me/Desktop/directory/file.txt");
file.getParentFile().mkdirs();

PrintWriter printWriter = new PrintWriter(file);

Just to add to Ned's answer above: you can use this to redirect output to any object that implements a write(str) method.

This can be used to good effect to "catch" stdout output in a GUI application.

Here's a silly example in PyQt:

import sys
from PyQt4 import QtGui

class OutputWindow(QtGui.QPlainTextEdit):
    def write(self, txt):
        self.appendPlainText(str(txt))

app = QtGui.QApplication(sys.argv)
out = OutputWindow()
sys.stdout=out
out.show()
print "hello world !"

this is because your project has been linked to a git-hub repository, and the file having question mark on it, is not been added yet. if you want to remove this sign you will have to add this file to git-hub repository.

To fix the indentation and formatting in all files of your solution:

1. Install the Format All Files extension => close VS, execute the .vsix file and reopen VS;
2. Menu Tools > Options... > Text Editor > All Languages > Tabs:
   1. Click on Smart (for resolving conflicts);
   2. Type the Tab Size and Indent Size you want (e.g. 2);
   3. Click on Insert Spaces if you want to replace tabs by spaces;
3. In the Solution Explorer (Ctrl+Alt+L) right click in any file and choose from the menu Format All Files (near the bottom).

This will recursively open and save all files in your solution, setting the indentation you defined above.

You might want to check other programming languages tabs (Options...) for Code Style > Formatting as well.

I don't know if this is still the recommended thing to use but the "Object Linking and Embedding" framework allows you to embed certain objects/controls directly into your application. This will probably only work for certain applications, I'm not sure if Notepad is one of them. For really simple things like notepad, you'll probably have an easier time just working with the text box controls provided by whatever medium you're using (e.g. WinForms).

Here's a link to OLE info to get started:

http://en.wikipedia.org/wiki/Object_Linking_and_Embedding

It gives out a string of max 200 characters OR 200 normal characters OR 200 characters followed by '...'

$ur_str= (strlen($ur_str) > 200) ? substr($ur_str,0,200).'...' :$ur_str;

Following are the differences between BufferedReader and Scanner

1. BufferedReader only read data but scanner also parse data.
2. you can only read String using BufferedReader, but you can read int, long or float using Scanner.
3. BufferedReader is older from Scanner,it exists from jdk 1.1 while Scanner was added on JDK 5 release.
4. The Buffer size of BufferedReader is large(8KB) as compared to 1KB of Scanner.
5. BufferedReader is more suitable for reading file with long String while Scanner is more suitable for reading small user input from command prompt.
6. BufferedReader is synchronized but Scanner is not, which means you cannot share Scanner among multiple threads.
7. BufferedReader is faster than Scanner because it doesn't spent time on parsing
8. BufferedReader is a bit faster as compared to Scanner
9. BufferedReader is from java.io package and Scanner is from java.util package on basis of the points we can select our choice.

Fwiw, I had this problem when running check_nrpe on a system that had the zenoss monitoring system installed. To add to the confusion, it worked fine as root user but not as zenoss user.

I found out that the zenoss user had an LD_LIBRARY_PATH that caused it to use zenoss libraries, which issue these warnings. Ie:

root@monitoring:$ echo $LD_LIBRARY_PATH

su - zenoss
zenoss@monitoring:/root$ echo $LD_LIBRARY_PATH
/usr/local/zenoss/python/lib:/usr/local/zenoss/mysql/lib:/usr/local/zenoss/zenoss/lib:/usr/local/zenoss/common/lib::
zenoss@monitoring:/root$ /usr/lib/nagios/plugins/check_nrpe -H 192.168.61.61 -p 6969 -c check_mq
/usr/lib/nagios/plugins/check_nrpe: /usr/local/zenoss/common/lib/libcrypto.so.0.9.8: no version information available (required by /usr/lib/libssl.so.0.9.8)
(...)
zenoss@monitoring:/root$ LD_LIBRARY_PATH= /usr/lib/nagios/plugins/check_nrpe -H 192.168.61.61 -p 6969 -c check_mq
(...)

So anyway, what I'm trying to say: check your variables like LD_LIBRARY_PATH, LD_PRELOAD etc as well.

I use JavaScript and CSS to accomplish this. The JS function needs to be called once on init and on window resize. Just tested in Chrome.

HTML:

<video width="1920" height="1080" controls>
    <source src="./assets/video.mp4" type="video/mp4">
    Your browser does not support the video tag.
</video>

JavaScript:

function scaleVideo() {
    var vid = document.getElementsByTagName('video')[0];
    var w = window.innerWidth;
    var h = window.innerHeight;

    if (w/16 >= h/9) {
        vid.setAttribute('width', w);
        vid.setAttribute('height', 'auto');
    } else {
        vid.setAttribute('width', 'auto');
        vid.setAttribute('height', h);
    }
}

CSS:

video {
    position:absolute;
    left:50%;
    top:50%;
    -webkit-transform:translate(-50%,-50%);
    transform:translate(-50%,-50%);
}

User Defined Class Array List Example

import java.util.*;  

public class UserDefinedClassInArrayList {

    public static void main(String[] args) {

        //Creating user defined class objects  
        Student s1=new Student(1,"AAA",13);  
        Student s2=new Student(2,"BBB",14);  
        Student s3=new Student(3,"CCC",15); 

        ArrayList<Student> al=new ArrayList<Student>();
        al.add(s1);
        al.add(s2);  
        al.add(s3);  

        Iterator itr=al.iterator();  

        //traverse elements of ArrayList object  
        while(itr.hasNext()){  
            Student st=(Student)itr.next();  
            System.out.println(st.rollno+" "+st.name+" "+st.age);  
        }  
    }
}

class Student{  
    int rollno;  
    String name;  
    int age;  
    Student(int rollno,String name,int age){  
        this.rollno=rollno;  
        this.name=name;  
        this.age=age;  
    }  
} 

Program Output:

1 AAA 13

2 BBB 14

3 CCC 15

What is JSON?

JavaScript Object Notation (JSON) is a lightweight data-interchange format inspired by the object literals of JavaScript.

JSON values can consist of:

objects (collections of name-value pairs) arrays (ordered lists of values) strings (in double quotes) numbers true, false, or null

JSON is language independent.

JSON with PHP?

After PHP Version 5.2.0, JSON extension is decodes and encodes functionalities as default.

Json_encode - returns the JSON representation of values Json_decode - Decodes the JSON String Json_last_error - Returns the last error occured.

JSON Syntax and Rules?

JSON syntax is derived from JavaScript object notation syntax:

Data is in name/value pairs Data is separated by commas Curly braces hold objects Square brackets hold arrays

Just in case...this works for me. Sorry for specific version of OpenSSL, but might be desirable.

# On macOS, search Homebrew for keg-only versions of OpenSSL

    execute_process(
        COMMAND brew --prefix OpenSSL

        OUTPUT_VARIABLE BREW_OPENSSL_PREFIX
        OUTPUT_STRIP_TRAILING_WHITESPACE
    )
    if (BREW_OPENSSL EQUAL 0 AND EXISTS "${BREW_OPENSSL_PREFIX}")
        message(STATUS "Found OpenSSL keg installed by Homebrew at ${BREW_OPENSSL_PREFIX}")
        set(OPENSSL_ROOT_DIR "${BREW_OPENSSL_PREFIX}/")
        set(OPENSSL_INCLUDE_DIR "${BREW_OPENSSL_PREFIX}/include")
        set(OPENSSL_LIBRARIES "${BREW_OPENSSL_PREFIX}/lib")

  message(STATUS "Found OpenSSL ${OPENSSL_VERSION}")
else()
  message(STATUS "OpenSSL Not Found")

_x000D_
li::before {_x000D_

Will work in all browsers, including IE from version 8 and up.

IMO, the provider is telling you to change the service endpoint (i.e. where to reach the web service), not the client endpoint (I don't understand what this could be). To change the service endpoint, you basically have two options.

Use the Binding Provider to set the endpoint URL

The first option is to change the BindingProvider.ENDPOINT_ADDRESS_PROPERTY property value of the BindingProvider (every proxy implements javax.xml.ws.BindingProvider interface):

...
EchoService service = new EchoService();
Echo port = service.getEchoPort();

/* Set NEW Endpoint Location */
String endpointURL = "http://NEW_ENDPOINT_URL";
BindingProvider bp = (BindingProvider)port;
bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endpointURL);

System.out.println("Server said: " + echo.echo(args[0]));
...

The drawback is that this only works when the original WSDL is still accessible. Not recommended.

Use the WSDL to get the endpoint URL

The second option is to get the endpoint URL from the WSDL.

...
URL newEndpoint = new URL("NEW_ENDPOINT_URL");
QName qname = new QName("http://ws.mycompany.tld","EchoService"); 

EchoService service = new EchoService(newEndpoint, qname);
Echo port = service.getEchoPort();

System.out.println("Server said: " + echo.echo(args[0]));
...

Use a list instead and replace your foreach loop with a for loop:

@model IList<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()

    @for (var i = 0; i < Model.Count; i++) 
    {
        <tr>
            <td>
                @Html.HiddenFor(x => x[i].IP)           
                @Html.CheckBoxFor(x => x[i].Checked)
            </td>
            <td>
                @Html.DisplayFor(x => x[i].IP)
            </td>
        </tr>
    }
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

Alternatively you could use an editor template:

@model IEnumerable<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()
    @Html.EditorForModel()   
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

and then define the template ~/Views/Shared/EditorTemplates/BlockedIPViewModel.cshtml which will automatically be rendered for each element of the collection:

@model BlockedIPViewModel
<tr>
    <td>
        @Html.HiddenFor(x => x.IP)
        @Html.CheckBoxFor(x => x.Checked)
    </td>
    <td>
        @Html.DisplayFor(x => x.IP)
    </td>
</tr>

The reason you were getting null in your controller is because you didn't respect the naming convention for your input fields that the default model binder expects to successfully bind to a list. I invite you to read the following article.

Once you have read it, look at the generated HTML (and more specifically the names of the input fields) with my example and yours. Then compare and you will understand why yours doesn't work.

int i = 1;
int j = 1;

int k = i++; // post increment
int l = ++j; // pre increment

std::cout << k; // prints 1
std::cout << l; // prints 2

Post increment implies the value i is incremented after it has been assigned to k. However, pre increment implies the value j is incremented before it is assigned to l.

The same applies for decrement.

It's Work for me.

It may sound silly but in my case the USB cable was too long (even if good quality). It worked with my tablet but not with the phone. To check this, if you run on Linux run lsusb to make sure that your device is at least officially connect to the usb port.

NOTE: The following tables were taken from some site when I was doing some R&D on the database. So the naming convention is not proper.

For me, the problem was, my parent table had the different character set than that of the one which I was creating.

Parent Table (PRODUCTS)

products | CREATE TABLE `products` (
  `productCode` varchar(15) NOT NULL,
  `productName` varchar(70) NOT NULL,
  `productLine` varchar(50) NOT NULL,
  `productScale` varchar(10) NOT NULL,
  `productVendor` varchar(50) NOT NULL,
  `productDescription` text NOT NULL,
  `quantityInStock` smallint(6) NOT NULL,
  `buyPrice` decimal(10,2) NOT NULL,
  `msrp` decimal(10,2) NOT NULL,
  PRIMARY KEY (`productCode`),
  KEY `productLine` (`productLine`),
  CONSTRAINT `products_ibfk_1` FOREIGN KEY (`productLine`) REFERENCES `productlines` (`productLine`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1

Child Table which had a problem (PRICE_LOGS)

price_logs | CREATE TABLE `price_logs` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `productCode` varchar(15) DEFAULT NULL,
  `old_price` decimal(20,2) NOT NULL,
  `new_price` decimal(20,2) NOT NULL,
  `added_on` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`),
  KEY `productCode` (`productCode`),
  CONSTRAINT `price_logs_ibfk_1` FOREIGN KEY (`productCode`) REFERENCES `products` (`productCode`) ON DELETE CASCADE ON UPDATE CASCADE
);

MODIFIED TO

price_logs | CREATE TABLE `price_logs` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `productCode` varchar(15) DEFAULT NULL,
  `old_price` decimal(20,2) NOT NULL,
  `new_price` decimal(20,2) NOT NULL,
  `added_on` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`),
  KEY `productCode` (`productCode`),
  CONSTRAINT `price_logs_ibfk_1` FOREIGN KEY (`productCode`) REFERENCES `products` (`productCode`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=latin1 

Also if you want to do something like ClassB.Run("thing");, make sure the Method Run(); is static or you could call it like this: thing.Run("thing");.

Or you can simply calculate it using filter, here's the function I use:

ma <- function(x, n = 5){filter(x, rep(1 / n, n), sides = 2)}

If you use dplyr, be careful to specify stats::filter in the function above.

jupyter notebook --notebook-dir=%WORKING_DIR%,

where %WORKING_DIR% (H:\data\ML) - directory where you're going to work

It is the simplest one-line command way, IMHO

Intent eventIntentMessage =getPackageManager()
 .getLaunchIntentForPackage(Telephony.Sms.getDefaultSmsPackage(getApplicationContext));
startActivity(eventIntentMessage);

You can pass string parameters to JavaScript functions like below code:

I passed three parameters where the third one is a string parameter.

var btn ="<input type='button' onclick='RoomIsReadyFunc(" + ID + "," + RefId + ",\"" + YourString + "\");'  value='Room is Ready' />";

// Your JavaScript function

function RoomIsReadyFunc(ID, RefId, YourString)
{
    alert(ID);
    alert(RefId);
    alert(YourString);
}

You can create a method to initialize the map like in this example below:

Map<String, Integer> initializeMap()
{
  Map<String, Integer> ret = new HashMap<>();

  //populate ret
  ...

  return ret;
}

//call
Map<String, Integer> map = initializeMap();

only use

 echo "<meta http-equiv='refresh' content='0'>";

right after insert query before } example

if(isset($_POST['submit']))
        {
SQL QUERY----
echo "<meta http-equiv='refresh' content='0'>";
}

TL;DR

1. Use 172.17.0.0/16 as IP address range, not 172.17.0.0/32.
2. Don't use localhost to connect to the PostgreSQL database on your host, but the host's IP instead. To keep the container portable, start the container with the --add-host=database:<host-ip> flag and use database as hostname for connecting to PostgreSQL.
3. Make sure PostgreSQL is configured to listen for connections on all IP addresses, not just on localhost. Look for the setting listen_addresses in PostgreSQL's configuration file, typically found in /etc/postgresql/9.3/main/postgresql.conf (credits to @DazmoNorton).

Long version

172.17.0.0/32 is not a range of IP addresses, but a single address (namly 172.17.0.0). No Docker container will ever get that address assigned, because it's the network address of the Docker bridge (docker0) interface.

When Docker starts, it will create a new bridge network interface, that you can easily see when calling ip a:

As you can see, in my case, the docker0 interface has the IP address 172.17.42.1 with a netmask of /16 (or 255.255.0.0). This means that the network address is 172.17.0.0/16.

The IP address is randomly assigned, but without any additional configuration, it will always be in the 172.17.0.0/16 network. For each Docker container, a random address from that range will be assigned.

This means, if you want to grant access from all possible containers to your database, use 172.17.0.0/16.

Datalist includes autocomplete and suggestions natively, it can also allow a user to enter a value that is not defined in the suggestions.

Select only gives you pre-defined options the user has to select from

You could encode your string using Base64 encoding on the JavaScript side and then decoding it on the server side with PHP (?).

JavaScript (Docu)

var wysiwyg_clean = window.btoa( wysiwyg );

PHP (Docu):

var wysiwyg = base64_decode( $_POST['wysiwyg'] );

The following steps are necessary to create .exe i.e. executable files which are as 1) Open visual studio framework 2) Then, create a new project or application 3) Build or execute your application by pressing F5

You can also use GUAVA and path escaper: UrlEscapers.urlFragmentEscaper().escape(relativePath)

I see the question has already been answered, but still want to add my 2 cents for the same.

I have also faced similar scenario in which I have to test the execution times for several approaches and hence written a small script, which calls timeit on all functions written in it.

The script is also available as github gist here.

Hope it will help you and others.

You can reset your form with:

$("#myform")[0].reset();

Since you want to call a non-static method from main, you just need to create an object of that class consisting non-static method and then you will be able to call the method using objectname.methodname(); But if you write the method as static then you won't need to create object and you will be able to call the method using methodname(); from main. And this will be more efficient as it will take less memory than the object created without static method.

If you're looking to preserve the existing branches and commit history, here's one way that worked for me.

git clone --mirror https://github.com/account/repo.git cloned-repo
cd cloned-repo
git push --mirror {URL of new (empty) repo}

# at this point only remote cloned-repo is correct, local has auto-generated repo structure with folders such as "branches" or "refs"
cd ..
rm -rf cloned-repo
git clone {URL of new (empty) repo}
# only now will you see the expected user-generated contents in local cloned-repo folder

# note: all non-master branches are avaialable, but git branch will not show them until you git checkout each of them
# to automatically checkout all remote branches use this loop:
for b in `git branch -r | grep -v -- '->'`; do git branch --track ${b##origin/} $b; done

Now, suppose you want to keep the source and destination repos in sync for a period of time. For example, there's still activity within the current remote repo that you want to bring over to the new/replacement repo.

git clone -o old https://github.com/account/repo.git my-repo
cd my-repo
git remote add new {URL of new repo}

To pull down the latest updates (assuming you have no local changes):

git checkout {branch(es) of interest}
git pull old
git push --all new

NB: I have yet to use submodules, so I don't know what additional steps might be required if you have them.

Apache's Multi-Processing Modules (MPMs) are responsible for binding to network ports on the machine, accepting requests, and dispatching children to handle the requests (http://httpd.apache.org/docs/2.2/mpm.html).

They're like any other Apache module, except that just one and only one MPM must be loaded into the server at any time. MPMs are chosen during configuration and compiled into the server by using the argument --with-mpm=NAME with the configure script where NAME is the name of the desired MPM.

Apache will use a default MPM for each operating system unless a different one is choosen at compile-time (for instance on Windows mpm_winnt is used by default). Here's the list of operating systems and their default MPMs:

• BeOS beos
• Netware mpm_netware
• OS/2 mpmt_os2
• Unix/Linux prefork (update for Apache version = 2.4: prefork, worker, or event, depending on platform capabilities)
• Windows mpm_winnt

To check what modules are compiled into the server use the command-line option -l (here is the documentation). For instance on a Windows installation you might get something like:

> httpd -l
Compiled in modules:
  core.c
  mod_win32.c
  mpm_winnt.c
  http_core.c
  mod_so.c

As of version 2.2 this is the list of available core features and MPM modules:

• core - Core Apache HTTP Server features that are always available
• mpm_common - A collection of directives that are implemented by more than one multi-processing module (MPM)
• beos - This Multi-Processing Module is optimized for BeOS.
• event - An experimental variant of the standard worker MPM
• mpm_netware Multi-Processing Module implementing an exclusively threaded web server optimized for Novell NetWare
• mpmt_os2 Hybrid multi-process, multi-threaded MPM for OS/2
• prefork Implements a non-threaded, pre-forking web server
• mpm_winnt - This Multi-Processing Module is optimized for Windows NT.
• worker - Multi-Processing Module implementing a hybrid multi-threaded multi-process web server

Now, to the difference between prefork and worker.

The prefork MPM

implements a non-threaded, pre-forking web server that handles requests in a manner similar to Apache 1.3. It is appropriate for sites that need to avoid threading for compatibility with non-thread-safe libraries. It is also the best MPM for isolating each request, so that a problem with a single request will not affect any other.

The worker MPM implements a hybrid multi-process multi-threaded server and gives better performance, hence it should be preferred unless one is using other modules that contain non-thread-safe libraries (see also this discussion or this on Serverfault).

I found @naota's solution useful, and extended it to use dates as well

//taken from StackOverflow:
//https://stackoverflow.com/questions/3880615/how-can-i-determine-whether-a-given-string-represents-a-date
function isDate(val) {
    var d = new Date(val);
    return !isNaN(d.valueOf());
}

var getVal = function(elm, n){
  var v = $(elm).children('td').eq(n).text().toUpperCase();
  if($.isNumeric(v)){
    v = parseFloat(v,10);
    return v;
  }
  if (isDate(v)) {
    v = new Date(v);
    return v;
  }
  return v;
}

In my case, I was running Python in the minimal alpine docker image. It was missing root CA certificates. Fix:

apk update && apk add ca-certificates

Although I take the risk of not being popular I say they are not useful nowadays.

I think they were well intended and useful in the past when for example DELETE told the server to delete the resource found at supplied URL and PUT (with its sibling PATCH) told the server to do update in an idempotent manner.

Things evolved and URLs became virtual (see url rewriting for example) making resources lose their initial meaning of real folder/subforder/file and so, CRUD action verbs covered by HTTP protocol methods (GET, POST, PUT/PATCH, DELETE) lost track.

Let's take an example:

• /api/entity/list/{id} vs GET /api/entity/{id}
• /api/entity/add/{id} vs POST /api/entity
• /api/entity/edit/{id} vs PUT /api/entity/{id}
• /api/entity/delete/{id} vs DELETE /api/entity/{id}

On the left side is not written the HTTP method, essentially it doesn't matter (POST and GET are enough) and on the right side appropriate HTTP methods are used.

Right side looks elegant, clean and professional. Imagine now you have to maintain a code that's been using the elegant API and you have to search where deletion call is done. You'll search for "api/entity" and among results you'll have to see which one is doing DELETE. Or even worse, you have a junior programmer which by mistake switched PUT with DELETE and as URL is the same shit happened.

In my opinion putting the action verb in the URL has advantages over using the appropriate HTTP method for that action even if it's not so elegant. If you want to see where delete call is made you just have to search for "api/entity/delete" and you'll find it straight away.

Building an API without the whole HTTP array of methods makes it easier to be consumed and maintained afterwards

If you want to set the font-size as a percentage of the viewport width, use the vwunit:

#mydiv { font-size: 5vw; }

The other alternative is to use SVG embedded in the HTML. It will just be a few lines. The font-size attribute to the text element will be interpreted as "user units", for instance those the viewport is defined in terms of. So if you define viewport as 0 0 100 100, then a font-size of 1 will be one one-hundredth of the size of the svg element.

And no, there is no way to do this in CSS using calculations. The problem is that percentages used for font-size, including percentages inside a calculation, are interpreted in terms of the inherited font size, not the size of the container. CSS could use a unit called bw (box-width) for this purpose, so you could say div { font-size: 5bw; }, but I've never heard this proposed.

This also could be easiest way to add items in ListBox.

for (int i = 0; i < MyList.Count; i++)
{
        listBox1.Items.Add(MyList.ElementAt(i));
}

Further improvisation of this code can add items at runtime.

leftclickben answer worked for me, but I wanted a path from a given node back up the tree to the root, and these seemed to be going the other way, down the tree. So, I had to flip some of the fields around and renamed for clarity, and this works for me, in case this is what anyone else wants too--

item | parent
-------------
1    | null
2    | 1
3    | 1
4    | 2
5    | 4
6    | 3

and

select t.item_id as item, @pv:=t.parent as parent
from (select * from item_tree order by item_id desc) t
join
(select @pv:=6)tmp
where t.item_id=@pv;

gives:

item | parent
-------------
6    | 3
3    | 1
1    | null

git rebase -i allows you to conveniently edit any previous commits, except for the root commit. The following commands show you how to do this manually.

# tag the old root, "git rev-list ..." will return the hash of first commit
git tag root `git rev-list HEAD | tail -1`

# switch to a new branch pointing at the first commit
git checkout -b new-root root

# make any edits and then commit them with:
git commit --amend

# check out the previous branch (i.e. master)
git checkout @{-1}

# replace old root with amended version
git rebase --onto new-root root

# you might encounter merge conflicts, fix any conflicts and continue with:
# git rebase --continue

# delete the branch "new-root"
git branch -d new-root

# delete the tag "root"
git tag -d root

For people using @akashivskyy's answer to instantiate UIViewController and are having the exception:

fatal error: use of unimplemented initializer 'init(coder:)' for class

Quick tip:

Manually implement required init?(coder aDecoder: NSCoder) at your destination UIViewController that you are trying to instantiate

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
}

Helvetica Neue is a paid font, so you shouldn't @font-face it, as you'd be freely distributing a copyrighted font. It's included in Mac systems but not in windows/linux ones, so yes, plenty of your users wont have it installed. Anyway, you can use 'Arial Narrow' as a windows substitute, which is it's windows equivalent.

I thought my simple "all possible combination generator" might help someone, i think its a really good example for building something bigger and better

you can change N (characters) to any you like by just removing/adding from string array (you can change it to int as well). Current amount of characters is 36

you can also change K (size of the generated combinations) by just adding more loops, for each element, there must be one extra loop. Current size is 4

#include<iostream>

using namespace std;

int main() {
string num[] = {"0","1","2","3","4","5","6","7","8","9","a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z" };

for (int i1 = 0; i1 < sizeof(num)/sizeof(string); i1++) {
    for (int i2 = 0; i2 < sizeof(num)/sizeof(string); i2++) {
        for (int i3 = 0; i3 < sizeof(num)/sizeof(string); i3++) {
            for (int i4 = 0; i4 < sizeof(num)/sizeof(string); i4++) {
                cout << num[i1] << num[i2] << num[i3] << num[i4] << endl;
            }
        }
    }
}}

Result

0: A A A
1: B A A
2: C A A
3: A B A
4: B B A
5: C B A
6: A C A
7: B C A
8: C C A
9: A A B
...

just keep in mind that the amount of combinations can be ridicules.

--UPDATE--

a better way to generate all possible combinations would be with this code, which can be easily adjusted and configured in the "variables" section of the code.

#include<iostream>
#include<math.h>

int main() {
    //VARIABLES
    char chars[] = { 'A', 'B', 'C' };
    int password[4]{0};

    //SIZES OF VERIABLES
    int chars_length = sizeof(chars) / sizeof(char);
    int password_length = sizeof(password) / sizeof(int);

    //CYCKLE TROUGH ALL OF THE COMBINATIONS
    for (int i = 0; i < pow(chars_length, password_length); i++){
       
        //CYCKLE TROUGH ALL OF THE VERIABLES IN ARRAY
        for (int i2 = 0; i2 < password_length; i2++) {
            //IF VERIABLE IN "PASSWORD" ARRAY IS THE LAST VERIABLE IN CHAR "CHARS" ARRRAY
            if (password[i2] == chars_length) {
                //THEN INCREMENT THE NEXT VERIABLE IN "PASSWORD" ARRAY
                password[i2 + 1]++;
                //AND RESET THE VERIABLE BACK TO ZERO
                password[i2] = 0;
            }}

        //PRINT OUT FIRST COMBINATION
        std::cout << i << ": ";
        for (int i2 = 0; i2 < password_length; i2++) {
            std::cout << chars[password[i2]] << " ";
        }
        std::cout << "\n";

        //INCREMENT THE FIRST VERIABLE IN ARRAY
        password[0]++;
    }}

    

The startActivityForResult pattern is much better suited for what you're trying to achieve : http://developer.android.com/reference/android/app/Activity.html#StartingActivities

Try below code

public class MainActivity extends Activity {  

    Button button1;  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        textView1=(TextView)findViewById(R.id.textView1);  
        button1=(Button)findViewById(R.id.button1);  
        button1.setOnClickListener(new OnClickListener() {  
            @Override  
            public void onClick(View arg0) {  
                Intent intent=new Intent(MainActivity.this,SecondActivity.class);  
                startActivityForResult(intent, 2);// Activity is started with requestCode 2  
            }  
        });  
    }  
 // Call Back method  to get the Message form other Activity  
    @Override  
       protected void onActivityResult(int requestCode, int resultCode, Intent data)  
       {  
                 super.onActivityResult(requestCode, resultCode, data);  
                  // check if the request code is same as what is passed  here it is 2  
                   if(requestCode==2)  
                         {  
                          //do the things u wanted 
                         }  
     }  

} 

SecondActivity.class

public class SecondActivity extends Activity {  

    Button button1;  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_second);  

            button1=(Button)findViewById(R.id.button1);  
            button1.setOnClickListener(new OnClickListener() {  
                @Override  
                public void onClick(View arg0) {  
                    String message="hello ";  
                    Intent intent=new Intent();  
                    intent.putExtra("MESSAGE",message);  
                    setResult(2,intent);  
                    finish();//finishing activity  
                }  
            });  
    }  

}  

Let me know if it helped...

Try

html, body{
  margin:0 !important;
  padding:0 !important;
}

#ifndef MY_HEADER_H
# define MY_HEADER_H

//put your function headers here

#endif

MY_HEADER_H serves as a double-inclusion guard.

For the function declaration, you only need to define the signature, that is, without parameter names, like this:

int foo(char*);

If you really want to, you can also include the parameter's identifier, but it's not necessary because the identifier would only be used in a function's body (implementation), which in case of a header (parameter signature), it's missing.

This declares the function foo which accepts a char* and returns an int.

In your source file, you would have:

#include "my_header.h"

int foo(char* name) {
   //do stuff
   return 0;
}

Given this piece of HTML code:

<a href='https://facebook.com/'>Facebook</a>
<a href='https://google.ca/'>Google</a>
<input type='text' placeholder='an input box'>

We can use this JavaScript:

function checkTabPress(e) {
    'use strict';
    var ele = document.activeElement;

    if (e.keyCode === 9 && ele.nodeName.toLowerCase() === 'a') {
        console.log(ele.href);
    }
}

document.addEventListener('keyup', function (e) {
    checkTabPress(e);
}, false);

I have bound an event listener to the document element for the keyUp event, which triggers a function to check if the Tab key was pressed (or technically, released).

The function checks the currently focused element and whether the NodeName is a. If so, it enters the if block and, in my case, writes the value of the href property to the JavaScript console.

Here's a jsFiddle

One Eclipse window was already opened on my machine and when I tried to open another Eclipse instance, I got this error. I just closed my open Eclipse windows and then launched another. And there was no such error anymore :)

I had same problem and beside some values inside my table. Although I changed my Primary Key with

ALTER TABLEuser_customer_permissionDROP PRIMARY KEY , ADD PRIMARY KEY (id)

problem continued on my server. I created new field inside the table I transfered the values into new field and deleted old one, problem solved!!

I tried the other answers here as well as a few others. I even stopped and restarted the SQL services. Nothing worked.

However, restarting my computer did work.

Using the Windows FTP client you would want to use the -s:filename option to specify a script for the FTP client to run. The documentation specifically points out that you should not try to pipe input into the FTP client with a < character.

Execution of the script will start immediately, so it does work for username/password.

However, the security of this setup is questionable since you now have a username and password for the FTP server visible to anyone who decides to look at your batch file.

Either way, you can generate the script file on the fly from the batch file and then pass it to the FTP client like so:

@echo off

REM Generate the script. Will overwrite any existing temp.txt
echo open servername> temp.txt
echo username>> temp.txt
echo password>> temp.txt
echo get %1>> temp.txt
echo quit>> temp.txt

REM Launch FTP and pass it the script
ftp -s:temp.txt

REM Clean up.
del temp.txt

Replace servername, username, and password with your details and the batch file will generate the script as temp.txt launch ftp with the script and then delete the script.

If you are always getting the same file you can replace the %1 with the file name. If not you just launch the batchfile and provide the name of the file to get as an argument.

This weird bug happened to me while importing a Xamarin project into VS15. None of the solutions listed here worked for me. After a day of frustration I also ran into a problem similar to this: Visual Studio "Find" results in "No files were found to look in. Find stopped progress."

When clicking 'find all' in the search dialog, a popup informed me that other files could not be searched through. so i figured the reason 'go to definition' didn't work was due to the same bug, as looking for definitions in the same file did work.

the weird solution in the above link (pressing Ctrl+Scroll Lock or Ctrl+Break a few times) solved both problems for me.

Coloring of the code (which wasn't working when the 'Go to definition' functionality was broken) also immediately returned.

Currently, media organisation is possible.

The "problem" with the media library in wordpress is always interesting. Check the following plugin to solve this: WordPress Real Media Library. WP RML creates a virtual folder structure based on an own taxonomy.

It allows you to organize your wordpress media library in a nice way with folders. It is easy to use, just drag&drop your files and move it to a specific folder. Filter when inserting media or create a gallery from a folder.

Turn your WordPress media library to the next level with folders / categories. Get organized with thousands of images.

RML (Real Media Library) is one of the most wanted media wordpress plugins. It is easy to use and it allows you to organize your thousands of images in folders. It is similar to wordpress categories like in the posts.

Use your mouse (or touch) to drag and drop your files. Create, rename, delete or reorder your folders If you want to select a image from the “Select a image”-dialog (e. g. featured image) you can filter when inserting media. Just install this plugin and it works fine with all your image and media files. It also supports multisite.

If you buy, you get: Forever FREE updates and high quality and fast support.

From the product description i can quote. If you want to try the plugin, there is also a demo on the plugin page.

Update #1 (2017-01-27): Manage your uploads physically

A long time ago I started to open this thread and now there is a usable extension plugin for Real Media Library which allows you to physically manage your uploads folder.

Check out this plugin: https://wordpress.org/plugins/physical-custom-upload-folder/

Do you know the wp-content/uploads folder? There, the files are stored in year/month based folders. This can be a very complicated and mass process, especially when you are working with a FTP client like FileZilla.

Moving already uploaded files: This plugin does not allow to move the files physically when you move a file in the Real Media Library because WordPress uses the URL's in different places. It is very hard to maintain such a process. So this only works for new uploads.

Physical organisation on server?

(Please read on if you are developer) I as developer thought about a solution about this. Does it make sense to organize the uploads on server, too? Yes, i think. Many people ask to organize it physically. I think also that the process of moving files on server and updating the image references is very hard to develop. There are many plugins out now, which are saving the URLs in their own-created database-tables.

Please check this thread where i explained the problem: https://wordpress.stackexchange.com/questions/226675/physical-organization-of-wordpress-media-library-real-media-library-plugin

Although the question is solved, sharing knowledge for clarification of the correct meaning of the error.

The error says that the parameter needed to the concerned breaking function is not in the required format i.e. string or Buffer

The solution is to change the parameter to string

breakingFunction(JSON.stringify(offendingParameter), ... other params...);

or buffer

breakingFunction(BSON.serialize(offendingParameter), ... other params...);

One more solution below,

If the entire folder is removed and SVNis throwing the error "admin file .svn is missing", the following will be used to resolve the conflict to working state.

svn resolve --accept working "file / directory name "

Additionally, if you have restricted access to the database (IE: Can't use "Script Function as > CREATE To"), there is another option to get this query.

Find your View > right click > "Design".

This will give you the query you are looking for.

As already mentioned in the answer by robertc, Chrome blocks certain functionality, like the geo location with local files. An easier alternative to setting up an own web server would be to just start Chrome with the parameter --allow-file-access-from-files. Then you can use the geo location, provided you didn't turn it off in your settings.

How about "TIMESTAMPDIFF":

SELECT TIMESTAMPDIFF(SECOND,'2009-05-18','2009-07-29') from `post_statistics`

The gcc compiler is not in your $PATH. It means either you dont have gcc installed or it's not in your $PATH variable.

To install gcc use this: (run as root)

• Redhat base:

  yum groupinstall "Development Tools"
  

• Debian base:

  apt-get install build-essential
  

@Eddie Loeffen's answer seems to be the most popular answer to this question, but it has some bad long term effects. If you review the documentation page for System.Net.ServicePointManager.SecurityProtocol here the remarks section implies that the negotiation phase should just address this (and forcing the protocol is bad practice because in the future, TLS 1.2 will be compromised as well). However, we wouldn't be looking for this answer if it did.

Researching, it appears that the ALPN negotiation protocol is required to get to TLS1.2 in the negotiation phase. We took that as our starting point and tried newer versions of the .Net framework to see where support starts. We found that .Net 4.5.2 does not support negotiation to TLS 1.2, but .Net 4.6 does.

So, even though forcing TLS1.2 will get the job done now, I recommend that you upgrade to .Net 4.6 instead. Since this is a PCI DSS issue for June 2016, the window is short, but the new framework is a better answer.

UPDATE: Working from the comments, I built this:

ServicePointManager.SecurityProtocol = 0;    
foreach (SecurityProtocolType protocol in SecurityProtocolType.GetValues(typeof(SecurityProtocolType)))
    {
        switch (protocol)
        {
            case SecurityProtocolType.Ssl3:
            case SecurityProtocolType.Tls:
            case SecurityProtocolType.Tls11:
                break;
            default:
                ServicePointManager.SecurityProtocol |= protocol;
            break;
        }
    }

In order to validate the concept, I or'd together SSL3 and TLS1.2 and ran the code targeting a server that supports only TLS 1.0 and TLS 1.2 (1.1 is disabled). With the or'd protocols, it seems to connect fine. If I change to SSL3 and TLS 1.1, that failed to connect. My validation uses HttpWebRequest from System.Net and just calls GetResponse(). For instance, I tried this and failed:

        HttpWebRequest request = WebRequest.Create("https://www.contoso.com/my/web/resource") as HttpWebRequest;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls11;
        request.GetResponse();

while this worked:

        HttpWebRequest request = WebRequest.Create("https://www.contoso.com/my/web/resource") as HttpWebRequest;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12;
        request.GetResponse();

This has an advantage over forcing TLS 1.2 in that, if the .Net framework is upgraded so that there are more entries in the Enum, they will be supported by the code as is. It has a disadvantage over just using .Net 4.6 in that 4.6 uses ALPN and should support new protocols if no restriction is specified.

Edit 4/29/2019 - Microsoft published this article last October. It has a pretty good synopsis of their recommendation of how this should be done in the various versions of .net framework.

The problem I had that caused this error was that I was trying to insert null values into a NOT NULL column.

I like this quick shorthand variation -

export const equalsIgnoreCase = (str1, str2) => {
    return (!str1 && !str2) || (str1 && str2 && str1.toUpperCase() == str2.toUpperCase())
}

Quick in processing, and does what it is intended to.

With jQuery, you can try to call trigger:

$(window).trigger('resize');

Ljava.lang.String;@ is returned where you used string arrays as strings. Employee.getSelectCancel() does not seem to return a String[]

If you want to copy conditional formatting to another document you can use the "Copy to..." feature for the worksheet (click the tab with the name of the worksheet at the bottom) and copy the worksheet to the other document.

Then you can just copy what you want from that worksheet and right-click select "Paste special" -> "Paste conditional formatting only", as described earlier.

You'll need to add the other repository as a remote, then fetch its changes. From there you see the commit and you can cherry-pick it.

Like that:

git remote add other https://example.link/repository.git
git fetch other

Now you have all the information to simply do git cherry-pick.

More info about working with remotes here: https://git-scm.com/book/en/v2/Git-Basics-Working-with-Remotes

You can write this more succinctly by taking advantage of the observable filter method:

this.router.events.filter(event => event instanceof NavigationEnd).subscribe(() => {
      this.window.scrollTo(0, 0);
});

If you're having issues scrolling to the top when using the Angular Material 2 sidenav this will help. The window or document body won't have the scrollbar so you need to get the sidenav content container and scroll that element, otherwise try scrolling the window as a default.

this.router.events.filter(event => event instanceof NavigationEnd)
  .subscribe(() => {
      const contentContainer = document.querySelector('.mat-sidenav-content') || this.window;
      contentContainer.scrollTo(0, 0);
});

Also, the Angular CDK v6.x has a scrolling package now that might help with handling scrolling.

ROUTER LINK DIRECTIVE:

[routerLink]="link"                  //when u pass URL value from COMPONENT file
[routerLink]="['link','parameter']" //when you want to pass some parameters along with route

 routerLink="link"                  //when you directly pass some URL 
[routerLink]="['link']"              //when you directly pass some URL

After you've retrieved the reflect.Value of the field by using Field(i) you can get a interface value from it by calling Interface(). Said interface value then represents the value of the field.

There is no function to convert the value of the field to a concrete type as there are, as you may know, no generics in go. Thus, there is no function with the signature GetValue() T with T being the type of that field (which changes of course, depending on the field).

The closest you can achieve in go is GetValue() interface{} and this is exactly what reflect.Value.Interface() offers.

The following code illustrates how to get the values of each exported field in a struct using reflection (play):

import (
    "fmt"
    "reflect"
)

func main() {
    x := struct{Foo string; Bar int }{"foo", 2}

    v := reflect.ValueOf(x)

    values := make([]interface{}, v.NumField())

    for i := 0; i < v.NumField(); i++ {
        values[i] = v.Field(i).Interface()
    }

    fmt.Println(values)
}

JB hit the nail on the head. The only thing I can add is that Java 8 doesn't do pure parallel processing, it does paraquential. Yes I wrote the article and I've been doing F/J for thirty years so I do understand the issue.
