For MAC after doing lot of research it worked for me..! 1. Install the beyond compare and this will be installed in below location

/Applications/Beyond\ Compare.app/Contents/MacOS/bcomp

Please follow these steps to make bc as diff/merge tool in git http://www.scootersoftware.com/support.php?zz=kb_mac

This is the easiest way:

php -f /home/your_username/public_html/script.php

And if you want to log the script output to a file, add this to the end of the command:

>> /home/your_username/logs/someFile.txt 2>&1

This is an answer was only tested in MacOS but it will probably also work in Linux and Windows.

import numpy as np
import cv2

cap = cv2.VideoCapture(0)

# Get the Default resolutions

in visualstudio 2008 you could use this code :

   var _assembly = System.Reflection.Assembly
               .GetExecutingAssembly().GetName().CodeBase;

   var _path = System.IO.Path.GetDirectoryName(_assembly) ;

1. Add an Application Configuration File item to your project (Right -Click Project > Add item). This will create a file called app.config in your project.

2. Edit the file by adding entries like <add key="keyname" value="someValue" /> within the <appSettings> tag.

3. Add a reference to the System.Configuration dll, and reference the items in the config using code like ConfigurationManager.AppSettings["keyname"].

You did not provide your validate.php code so I'm confused. You have to pass the data in JSON Format when when mail is success. You can use json_encode(); PHP function for that.

Add json_encdoe in validate.php in last

mail($to, $subject, $message, $headers); 
echo json_encode(array('success'=>'true'));

JS Code

success: function(data){ 
     if(data.success == true){ 
       alert('success'); 
    } 

Hope it works

It's been a long time since I've worked in a Windows environment, but I would suggest that you look at using WMI.

After you exit the eclipse, there would be an specific failed reason. Mine is that the DISK IS FULL so the eclipse can't write into it anymore.

You should create custom helper for just changing string format except using controller call.

For better output format check this command:

There's no fixed time for retransmission. Simple implementations estimate the RTT (round-trip-time) and if no ACK to send data has been received in 2x that time then they re-send.

They then double the wait-time and re-send once more if again there is no reply. Rinse. Repeat.

More sophisticated systems make better estimates of how long it should take for the ACK as well as guesses about exactly which data has been lost.

The bottom-line is that there is no hard-and-fast rule about exactly when to retransmit. It's up to the implementation. All retransmissions are triggered solely by the sender based on lack of response from the receiver.

TCP never drops data so no, there is no way to indicate a server should forget about some segment.

Combination of Mritunjay and Bartu's answers are full answer to this question. I copying the full example.

<input class="form-control" type="email"  required="" placeholder="username"
 oninvalid="this.setCustomValidity('Please Enter valid email')"
 oninput="setCustomValidity('')"></input>

Here,

this.setCustomValidity('Please Enter valid email')" - Display the custom message on invalidated of the field

oninput="setCustomValidity('')" - Remove the invalidate message on validated filed.

The key is to encapsulate the expression in parentheses after the @ delimiter. You can make any compound expression work this way.

If you need performance, then you must test on your environment. No other way.

Here example code:

int tmp = 0;
String s = new String(new byte[64*1024]);
{
    long st = System.nanoTime();
    for(int i = 0, n = s.length(); i < n; i++) {
        tmp += s.charAt(i);
    }
    st = System.nanoTime() - st;
    System.out.println("1 " + st);
}

{
    long st = System.nanoTime();
    char[] ch = s.toCharArray();
    for(int i = 0, n = ch.length; i < n; i++) {
        tmp += ch[i];
    }
    st = System.nanoTime() - st;
    System.out.println("2 " + st);
}
{
    long st = System.nanoTime();
    for(char c : s.toCharArray()) {
        tmp += c;
    }
    st = System.nanoTime() - st;
    System.out.println("3 " + st);
}
System.out.println("" + tmp);

Use "IF DEFINED variable command" to test variable in batch file.

But if you want to test batch parameters, try below codes to avoid tricky input (such as "1 2" or ab^>cd)

set tmp="%1"
if "%tmp:"=.%"==".." (
    echo empty
) else (
    echo not empty
)

Something like this? Takes advantage of short-circuit evaluation. If the file does not exist, the whole conditional cannot be true, so python will not bother evaluation the second part.

os.path.exists("gogogo.php") and os.remove("gogogo.php")

Try to consolidate the syntax in a single line. this will clear the error

The easiest way is to use LINQ's Union method:

var aUb = A.Union(B).ToList();

Swift 3

// Default state (previously `.Normal`)
button.setImage(UIImage(named: "image1"), for: [])

// Highlighted
button.setImage(UIImage(named: "image2"), for: .highlighted)

// Selected
button.setImage(UIImage(named: "image3"), for: .selected)

// Selected + Highlighted
button.setImage(UIImage(named: "image4"), for: [.selected, .highlighted])

To set the background image we can use setBackgroundImage(_:for:)

Swift 2.x

// Normal
button.setImage(UIImage(named: "image1"), forState: .Normal)

// Highlighted
button.setImage(UIImage(named: "image2"), forState: .Highlighted)

// Selected
button.setImage(UIImage(named: "image3"), forState: .Selected)

// Selected + Highlighted
button.setImage(UIImage(named: "image4"), forState: [.Selected, .Highlighted])

There might be some deleted jar files already in build path. Right click on project. Properties->Java Build Path and removed deleted jar files from there.

You were probably changing the layout margin after it has been drawn. mOldTextView.invalidate() is useless. you needed to call requestLayout() on the parent to relayout the new configuration. When you moved the layout changing code before the drawing took place, everything worked fine.

You're nesting mocking inside of mocking. You're calling getSomeList(), which does some mocking, before you've finished the mocking for MyMainModel. Mockito doesn't like it when you do this.

Replace

@Test
public myTest(){
    MyMainModel mainModel =  Mockito.mock(MyMainModel.class);
    Mockito.when(mainModel.getList()).thenReturn(getSomeList()); --> Line 355
}

with

@Test
public myTest(){
    MyMainModel mainModel =  Mockito.mock(MyMainModel.class);
    List<SomeModel> someModelList = getSomeList();
    Mockito.when(mainModel.getList()).thenReturn(someModelList);
}

To understand why this causes a problem, you need to know a little about how Mockito works, and also be aware in what order expressions and statements are evaluated in Java.

Mockito can't read your source code, so in order to figure out what you are asking it to do, it relies a lot on static state. When you call a method on a mock object, Mockito records the details of the call in an internal list of invocations. The when method reads the last of these invocations off the list and records this invocation in the OngoingStubbing object it returns.

The line

Mockito.when(mainModel.getList()).thenReturn(someModelList);

causes the following interactions with Mockito:

• Mock method mainModel.getList() is called,
• Static method when is called,
• Method thenReturn is called on the OngoingStubbing object returned by the when method.

The thenReturn method can then instruct the mock it received via the OngoingStubbing method to handle any suitable call to the getList method to return someModelList.

In fact, as Mockito can't see your code, you can also write your mocking as follows:

mainModel.getList();
Mockito.when((List<SomeModel>)null).thenReturn(someModelList);

This style is somewhat less clear to read, especially since in this case the null has to be casted, but it generates the same sequence of interactions with Mockito and will achieve the same result as the line above.

However, the line

Mockito.when(mainModel.getList()).thenReturn(getSomeList());

causes the following interactions with Mockito:

1. Mock method mainModel.getList() is called,
2. Static method when is called,
3. A new mock of SomeModel is created (inside getSomeList()),
4. Mock method model.getName() is called,

At this point Mockito gets confused. It thought you were mocking mainModel.getList(), but now you're telling it you want to mock the model.getName() method. To Mockito, it looks like you're doing the following:

when(mainModel.getList());
// ...
when(model.getName()).thenReturn(...);

This looks silly to Mockito as it can't be sure what you're doing with mainModel.getList().

Note that we did not get to the thenReturn method call, as the JVM needs to evaluate the parameters to this method before it can call the method. In this case, this means calling the getSomeList() method.

Generally it is a bad design decision to rely on static state, as Mockito does, because it can lead to cases where the Principle of Least Astonishment is violated. However, Mockito's design does make for clear and expressive mocking, even if it leads to astonishment sometimes.

Finally, recent versions of Mockito add an extra line to the error message above. This extra line indicates you may be in the same situation as this question:

3: you are stubbing the behaviour of another mock inside before 'thenReturn' instruction if completed

You can't target the last instance of the class name in your list without JS.

However, you may not be entirely out-of-css-luck, depending on what you are wanting to achieve. For example, by using the next sibling selector, I have added a visual divider after the last of your .list elements here: http://jsbin.com/vejixisudo/edit?html,css,output

I have the same problem here, then I reinstalled mysql and it worked.

sudo apt-get install mysql-server mysql-common mysql-client

byte[] a = new byte[50];

char [] cArray= System.Text.Encoding.ASCII.GetString(a).ToCharArray();

From the URL thedixon posted

http://bytes.com/topic/c-sharp/answers/250261-byte-char

You cannot ToCharArray the byte without converting it to a string first.

To quote Jon Skeet there

There's no need for the copying here - just use Encoding.GetChars. However, there's no guarantee that ASCII is going to be the appropriate encoding to use.

All you need is the following:

\makeatletter
\def\sec#1{\def\tempa{#1}\futurelet\next\sec@i}% Save first argument
\def\sec@i{\ifx\next\bgroup\expandafter\sec@ii\else\expandafter\sec@end\fi}%Check brace
\def\sec@ii#1{\section*{\tempa\ and #1}}%Two args
\def\sec@end{\section*{\tempa}}%Single args
\makeatother

\sec{Hello}
%Output: Hello
\sec{Hello}{Hi}
%Output: Hello and Hi

Got a better approach to implement the animating FAB menu without using any library or to write huge xml code for animations. hope this will help in future for someone who needs a simple way to implement this.

Just using animate().translationY() function, you can animate any view up or down just I did in my below code, check complete code in github. In case you are looking for the same code in kotlin, you can checkout the kotlin code repo Animating FAB Menu.

first define all your FAB at same place so they overlap each other, remember on top the FAB should be that you want to click and to show other. eg:

    <android.support.design.widget.FloatingActionButton
    android:id="@+id/fab3"
    android:layout_width="@dimen/standard_45"
    android:layout_height="@dimen/standard_45"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/standard_21"
    app:srcCompat="@android:drawable/ic_btn_speak_now" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab2"
    android:layout_width="@dimen/standard_45"
    android:layout_height="@dimen/standard_45"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/standard_21"
    app:srcCompat="@android:drawable/ic_menu_camera" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab1"
    android:layout_width="@dimen/standard_45"
    android:layout_height="@dimen/standard_45"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/standard_21"
    app:srcCompat="@android:drawable/ic_dialog_map" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_margin="@dimen/fab_margin"
    app:srcCompat="@android:drawable/ic_dialog_email" />

Now in your java class just define all your FAB and perform the click like shown below:

 FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab1 = (FloatingActionButton) findViewById(R.id.fab1);
    fab2 = (FloatingActionButton) findViewById(R.id.fab2);
    fab3 = (FloatingActionButton) findViewById(R.id.fab3);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if(!isFABOpen){
                showFABMenu();
            }else{
                closeFABMenu();
            }
        }
    });

Use the animation().translationY() to animate your FAB,I prefer you to use the attribute of this method in DP since only using an int will effect the display compatibility with higher resolution or lower resolution. as shown below:

 private void showFABMenu(){
    isFABOpen=true;
    fab1.animate().translationY(-getResources().getDimension(R.dimen.standard_55));
    fab2.animate().translationY(-getResources().getDimension(R.dimen.standard_105));
    fab3.animate().translationY(-getResources().getDimension(R.dimen.standard_155));
}

private void closeFABMenu(){
    isFABOpen=false;
    fab1.animate().translationY(0);
    fab2.animate().translationY(0);
    fab3.animate().translationY(0);
}

Now define the above mentioned dimension inside res->values->dimens.xml as shown below:

    <dimen name="standard_55">55dp</dimen>
<dimen name="standard_105">105dp</dimen>
<dimen name="standard_155">155dp</dimen>

That's all hope this solution will help the people in future, who are searching for simple solution.

EDITED

If you want to add label over the FAB then simply take a horizontal LinearLayout and put the FAB with textview as label, and animate the layouts if find any issue doing this, you can check my sample code in github, I have handelled all backward compatibility issues in that sample code. check my sample code for FABMenu in Github

to close the FAB on Backpress, override onBackPress() as showen below:

    @Override
public void onBackPressed() {
    if(!isFABOpen){
        this.super.onBackPressed();
    }else{
        closeFABMenu();
    }
}

The Screenshot have the title as well with the FAB,because I take it from my sample app present ingithub

<?php 
$dateTime = new DateTime('now', new DateTimeZone('Asia/Kolkata')); 
echo $dateTime->format("d/m/y  H:i A"); 
?>

You can use this to display the date like this

22/06/15 10:46 AM

You could use the alternative syntax alternative syntax for control structures and break out of PHP:

<?php if ($something): ?>
    <some /> <tags /> <etc />
    <?=$shortButControversialWayOfPrintingAVariable ?>
    <?php /* A comment not visible in the HTML, but it is a bit of a pain to write */ ?>
<?php else: ?>
    <!-- else -->
<?php endif; ?>

To remove the variable from the current environment (not permanently):

set FOOBAR=

To permanently remove the variable from the user environment (which is the default place setx puts it):

REG delete HKCU\Environment /F /V FOOBAR

If the variable is set in the system environment (e.g. if you originally set it with setx /M), as an administrator run:

REG delete "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /F /V FOOBAR

Note: The REG commands above won't affect any existing processes (and some new processes that are forked from existing processes), so if it's important for the change to take effect immediately, the easiest and surest thing to do is log out and back in or reboot. If this isn't an option or you want to dig deeper, some of the other answers here have some great suggestions that may suit your use case.

Yes, you can modify state of objects inside your stream, but most often you should avoid modifying state of source of stream. From non-interference section of stream package documentation we can read that:

For most data sources, preventing interference means ensuring that the data source is not modified at all during the execution of the stream pipeline. The notable exception to this are streams whose sources are concurrent collections, which are specifically designed to handle concurrent modification. Concurrent stream sources are those whose Spliterator reports the CONCURRENT characteristic.

So this is OK

  List<User> users = getUsers();
  users.stream().forEach(u -> u.setProperty(value));
//                       ^    ^^^^^^^^^^^^^

but this in most cases is not

  users.stream().forEach(u -> users.remove(u));
//^^^^^                       ^^^^^^^^^^^^

and may throw ConcurrentModificationException or even other unexpected exceptions like NPE:

List<Integer> list = IntStream.range(0, 10).boxed().collect(Collectors.toList());

list.stream()
    .filter(i -> i > 5)
    .forEach(i -> list.remove(i));  //throws NullPointerException

When you use git push origin :staleStuff, it automatically removes origin/staleStuff, so when you ran git remote prune origin, you have pruned some branch that was removed by someone else. It's more likely that your co-workers now need to run git prune to get rid of branches you have removed.

So what exactly git remote prune does? Main idea: local branches (not tracking branches) are not touched by git remote prune command and should be removed manually.

Now, a real-world example for better understanding:

You have a remote repository with 2 branches: master and feature. Let's assume that you are working on both branches, so as a result you have these references in your local repository (full reference names are given to avoid any confusion):

• refs/heads/master (short name master)
• refs/heads/feature (short name feature)
• refs/remotes/origin/master (short name origin/master)
• refs/remotes/origin/feature (short name origin/feature)

Now, a typical scenario:

1. Some other developer finishes all work on the feature, merges it into master and removes feature branch from remote repository.
2. By default, when you do git fetch (or git pull), no references are removed from your local repository, so you still have all those 4 references.
3. You decide to clean them up, and run git remote prune origin.
4. git detects that feature branch no longer exists, so refs/remotes/origin/feature is a stale branch which should be removed.
5. Now you have 3 references, including refs/heads/feature, because git remote prune does not remove any refs/heads/* references.

It is possible to identify local branches, associated with remote tracking branches, by branch.<branch_name>.merge configuration parameter. This parameter is not really required for anything to work (probably except git pull), so it might be missing.

(updated with example & useful info from comments)

Actually it happens when the number of processes exceeds the limits set by the hosting provider.

To avoid either we need to enhance the capacity by hosting providers or we need to check in the code whether any process takes longer time (like background tasks).

This works for me in Ubuntu 17.10 (Artful Aardvark):

apt-get update
apt-get install build-essential

You don't need any webpack configuration for this..

In your component just give image path. By default react will know its in public directory.

<img src="/image.jpg" alt="image" />

You can also use this free plug-and-play extension:

http://www.magentocommerce.com/magento-connect/manage-customer-account-menu.html

This extension does not touch any of the Magento core files.

With this extension you are able to:

1. Decide per menu item to show or hide it with one click in the Magento backend.
2. Rename menu items easily.

ActiveSheet.UsedRange.Rows.Count + ActiveSheet.UsedRange.Rows(1).Row -1

Short. Safe. Fast. Will return the last non-empty row even if there are blank lines on top of the sheet, or anywhere else. Works also for an empty sheet (Excel reports 1 used row on an empty sheet so the expression will be 1). Tested and working on Excel 2002 and Excel 2010.

You can use pytz as well..

import datetime
import pytz
def utcnow():
    return datetime.datetime.now(tz=pytz.utc)
utcnow()
   datetime.datetime(2020, 8, 15, 14, 45, 19, 182703, tzinfo=<UTC>)
utcnow().isoformat()

'

2020-08-15T14:45:21.982600+00:00'

CREATE TABLE `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `dateCreated` datetime DEFAULT CURRENT_TIMESTAMP,
  `dateUpdated` datetime DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`),
  UNIQUE KEY `mobile_UNIQUE` (`mobile`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

By default, most of distribution uses Ctrl+F12.

Some OS distribution (in my case Xubuntu) which uses Xcfe, overrides Ctrl+F12 to "Workspace 12" switch.

You can do that simple with Files.size(new File(filename).toPath()).

The simplest way is to use slice. If x is your string variable then x[:-1] will return the string variable without the last character. (BTW, x[-1] is the last character in the string variable) You are looking for

my_file_path = '/home/ro/A_Python_Scripts/flask-auto/myDirectory/scarlett Johanson/1448543562.17.jpg/' my_file_path = my_file_path[:-1]

if ($elem.parents('.left').length) {

}

To create all intermediate-level destination directories you could use os.makedirs() before copying:

import os
import shutil

srcfile = 'a/long/long/path/to/file.py'
dstroot = '/home/myhome/new_folder'


assert not os.path.isabs(srcfile)
dstdir =  os.path.join(dstroot, os.path.dirname(srcfile))

os.makedirs(dstdir) # create all directories, raise an error if it already exists
shutil.copy(srcfile, dstdir)

For above query apply below css for a

I'm developing a simple JavaFX11 application with SQLite Database in Eclipse IDE. To generate report I added Jasper jars. Suddenly it throws "THIS" error.

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

It was running good (BEFORE THIS ADDITION). But suddenly!

I'm not using maven or other managers for this simple application. I'm adding jars manually.

I created "User Library" and added my jars from external folders.

PROBLEM OCCURING AREA: My "User Library" are marked as system library. I just removed the marking. Now its not a system library. "NOW MY PROJECT WORKING GOOD".

DEBUG MYSELF: Tried other things: AT RUN CONFIGURATION: Try, removing library and add jars one-by-one and see. - here you have to delete all jars one by one, there is no select all and remove in eclipse right now in run configuration. So the error messages changes form one jars to another.

Hope this helps someone.

  self.contents = md.post_match
  self.metadata = YAML.load(md[:metadata])

df=pd.DataFrame(['Text to copy'])
df.to_clipboard(index=False,header=False)

I wrote a little wrapper for it that I put in my ipython profile <3

Your Delivery class is internal (the default visibility for classes), however the property (and presumably the containing class) are public, so the property is more accessible than the Delivery class. You need to either make Delivery public, or restrict the visibility of the thelivery property.

Using real life example (with some simplifications):

1. Imagine a freight train with freight cars as analogy to a list.
2. You can put a cargo in a freight car if the cargo has the same or smaller size than the freight car = <? super FreightCarSize>
3. You can unload a cargo from a freight car if you have enough place (more than the size of the cargo) in your depot = <? extends DepotSize>

Make sure to watch your selectors. You appear to have forgotten the # for div2. Additionally, you can toggle the visibility of many elements at once with .toggle():

// Short-form of `document.ready`
$(function(){
    $("#div2").hide();
    $("#preview").on("click", function(){
        $("#div1, #div2").toggle();
    });
});

Demo: http://jsfiddle.net/dJg8N/

$array = array('Item 1');

array_push($array,'Item 2');

or

$array[] = 'Item 2';

CheckBoxFor takes a bool, you're passing a List<CheckBoxes> to it. You'd need to do:

@for (int i = 0; i < Model.EmploymentType.Count; i++)
{
    @Html.CheckBoxFor(m => m.EmploymentType[i].Checked, new { id = "employmentType_" + i })
    @Html.HiddenFor(m => m.EmploymentType[i].Text)
    @Html.DisplayFor(m => m.EmploymentType[i].Text)
}

Notice I've added a HiddenFor for the Text property too, otherwise you'd lose that when you posted the form, so you wouldn't know which items you'd checked.

Edit, as shown in your comments, your EmploymentType list is null when the view is served. You'll need to populate that too, by doing this in your action method:

public ActionResult YourActionMethod()
{
    CareerForm model = new CareerForm();

    model.EmploymentType = new List<CheckBox>
    {
        new CheckBox { Text = "Fulltime" },
        new CheckBox { Text = "Partly" },
        new CheckBox { Text = "Contract" }
    };

    return View(model);
}

Maybe try kint: composer require raveren/kint "dev-master" More information: Why is my debug data unformatted?

You can do the same with build.gradle

sonarqube {
properties {
    property "sonar.exclusions", "**/src/java/test/**/*.java"
  }
}

And if you want to exclude more files/directories then:

sonarqube {
properties {
    property "sonar.exclusions", "**/src/java/test/**/*.java, **/src/java/main/**/*.java"
  }
}

Ok, try this:

Get the image with the transparent circle - http://i39.tinypic.com/15s97vd.png Put that image in a html element and change that element's background color via css. This way you get the logo with the circle in the color defined in the stylesheet.

The html

<div class="badassColorChangingLogo">
    <img src="http://i39.tinypic.com/15s97vd.png" /> 
    Or download the image and change the path to the downloaded image in your machine
</div>

The css

div.badassColorChangingLogo{
    background-color:white;
}
div.badassColorChangingLogo:hover{
    background-color:blue;
}

Keep in mind that this wont work on non-alpha capable browsers like ie6, and ie7. for ie you can use a js fix. Google ddbelated png fix and you can get the script.

I faced the same problem,Eclipse splash screen for a second and it disappears.Then i noticed due to auto update of java there are two java version installed in my system. when i uninstalled one eclipse started working.

Thanks you..

<?php

$string = 'foo';

if (preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $string))
{
    // one or more of the 'special characters' found in $string
}

You don't need an index match formula. You can use this array formula. You have to press CTL + SHIFT + ENTER after you enter the formula.

=MAX(IF((A1:A6=A10)*(B1:B6=B10),C1:F6))

SNAPSHOT

You have an extra closing } in your function.

var nav = document.getElementsByClassName('nav-coll');
for (var i = 0; i < button.length; i++) {
    nav[i].addEventListener('click',function(){
            console.log('haha');
        }        // <== remove this brace
    }, false);
};

You really should be using something like JSHint or JSLint to help find these things. These tools integrate with many editors and IDEs, or you can just paste a code fragment into the above web sites and ask for an analysis.

I think this question has been pretty well answered, but I just wanted to add a method using Python 3.8 and the new assignment expression (walrus operator) since it is stylistically simple.

import socket

host = "127.0.0.1"
port = 31337
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host,port))
s.listen()
con, addr = s.accept()
msg_list = []

while (walrus_msg := con.recv(3)) != b'\r\n':
    msg_list.append(walrus_msg)

print(msg_list)

In this case, 3 bytes are received from the socket and immediately assigned to walrus_msg. Once the socket receives a b'\r\n' it breaks the loop. walrus_msg are added to a msg_list and printed after the loop breaks. This script is basic but was tested and works with a telnet session.

NOTE: The parenthesis around the (walrus_msg := con.recv(3)) are needed. Without this, while walrus_msg := con.recv(3) != b'\r\n': evaluates walrus_msg to True instead of the actual data on the socket.

New Version queries have a different format

To reach a lat long by url use (e.g.)

https://www.google.com/maps/search/-15.924,-5.719

%UserProfile%\Local Settings\Application Data\Google\Chrome\User Data\Default\Cache

paste this in your address bar and enter, you will get all the files

just rename the files extension into the extension which u r looking.

ie. open command prompt then

C:\>cd %UserProfile%\Local Settings\Application Data\Google\Chrome\User Data\Default\Cache

then

C:\Users\User\AppData\Local\Google\Chrome\User Data\Default\Cache>ren *.* *.jpg

You should have to manually delete apps. got to Setting-> Application Management -> Running application, tap on it and you can remove, stop apps from there.

I want the all to resolve when all the chains have been resolved.

Sure, then just pass the promise of each chain into the all() instead of the initial promises:

$q.all([one.promise, two.promise, three.promise]).then(function() {
    console.log("ALL INITIAL PROMISES RESOLVED");
});

var onechain   = one.promise.then(success).then(success),
    twochain   = two.promise.then(success),
    threechain = three.promise.then(success).then(success).then(success);

$q.all([onechain, twochain, threechain]).then(function() {
    console.log("ALL PROMISES RESOLVED");
});

Consider the below sample code snippet which demonstrates how to dismiss a dialog fragment safely:

DialogFragment dialogFragment = new DialogFragment();

/** 
 * do something
 */

// Now you want to dismiss the dialog fragment
if (dialogFragment.getDialog() != null && dialogFragment.getDialog().isShowing())
{
    // Dismiss the dialog
    dialogFragment.dismiss();
}

Happy Coding!

This code make clean dataframe:

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

You need to use "\n" not '\n' in your gsub. The different quote marks behave differently.

Double quotes " allow character expansion and expression interpolation ie. they let you use escaped control chars like \n to represent their true value, in this case, newline, and allow the use of #{expression} so you can weave variables and, well, pretty much any ruby expression you like into the text.

While on the other hand, single quotes ' treat the string literally, so there's no expansion, replacement, interpolation or what have you.

In this particular case, it's better to use either the .delete or .tr String method to delete the newlines.

Don't use wait(), use either android.os.SystemClock.sleep(1000); or Thread.sleep(1000);.

The main difference between them is that Thread.sleep() can be interrupted early -- you'll be told, but it's still not the full second. The android.os call will not wake early.

You can do it from code by placing the following code in Window Loaded event handler, for example:

yourComboBox.ItemsSource = Enum.GetValues(typeof(EffectStyle)).Cast<EffectStyle>();

If you need to bind it in XAML you need to use ObjectDataProvider to create object available as binding source:

<Window x:Class="YourNamespace.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:System="clr-namespace:System;assembly=mscorlib"
        xmlns:StyleAlias="clr-namespace:Motion.VideoEffects">
    <Window.Resources>
        <ObjectDataProvider x:Key="dataFromEnum" MethodName="GetValues"
                            ObjectType="{x:Type System:Enum}">
            <ObjectDataProvider.MethodParameters>
                <x:Type TypeName="StyleAlias:EffectStyle"/>
            </ObjectDataProvider.MethodParameters>
        </ObjectDataProvider>
    </Window.Resources>
    <Grid>
        <ComboBox ItemsSource="{Binding Source={StaticResource dataFromEnum}}"
                  SelectedItem="{Binding Path=CurrentEffectStyle}" />
    </Grid>
</Window>

Draw attention on the next code:

xmlns:System="clr-namespace:System;assembly=mscorlib"
xmlns:StyleAlias="clr-namespace:Motion.VideoEffects"

Guide how to map namespace and assembly you can read on MSDN.

Above answers are pretty sufficient. Additional to the onChange, if you upload a file using drag and drop events, you can get the file in drop event by accessing eventArgs.dataTransfer.files.

Here's what you need to remember:

• It's 2 billion.
• The next three triplets are increasing like so: 100s, 400s, 600s
• The first and the last triplet need 3 added to them so they get rounded up to 50 (eg 147 + 3 = 150 & 647 + 3 = 650)
• The second triplet needs 3 subtracted from it to round it down to 80 (eg 483 - 3 = 480)

Hence 2, 147, 483, 647

I had exactly the same issue: was cleaning up my folders, rearranging and moving files. I entered: git rm . and hit enter; and then felt my bowels loosen a bit. Luckily, I didn't type in git commit -m "" straightaway.

However, the following command

git checkout .

restored everything, and saved my life.

If your database client connects with TCP/IP and you have ident auth configured in your pg_hba.conf check that you have an identd installed and running. This is mandatory even if you have only local clients connecting to "localhost".

Also beware that nowadays the identd may have to be IPv6 enabled for Postgresql to welcome clients which connect to localhost.

Python strings are immutable so what you are trying to do in C will be simply impossible in python. You will have to create a new string.

I would like to read some characters from a string and put it into other string.

Then use a string slice:

>>> s1 = 'Hello world!!'
>>> s2 = s1[6:12]
>>> print s2
world!

I solved this, without having to completely reinstall Visual Studio 2013.

For those who may come across this in the future, the following steps worked for me:

1. Run the ISO (or vs_professional.exe).

2. If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3

   • Click the link for 'examine the log file' and look near the bottom of the log, for this line:

   • open regedit.exe and do an Edit > Find... for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}. This was found in:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}

   • Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13:

   • Exit the registry

3. Run the ISO (or vs_professional.exe) again. If it has a repair button like the image below, you can skip to step 4.

   

   • Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes.

4. Run the ISO (or vs_professional.exe) again. This time repair should be visible.

5. Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes.

Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product:

Hope this helps somebody in the future!

Assuming you have lost these while upgrading versions like I did, follow these steps to restore:

1. Open SQL Developer
2. Right click on Connections
3. Chose Import Connections...
4. Click Browse (should open to your SQL Developer directory)
5. Drill down to "systemx.x.xx.xx" (replace x's with your previous version of SQL Developer)
6. Find and drill into a folder that has ".db.connection." in it (for me, it was in o.jdeveloper.db.connection.11.1.1.4.37.59.48)
7. select connections.xml and click open

You should then see the list of connections that will be imported

See if the BSD C Standard Library has fcvt(). You could start with the source for it that rather than writing your code from scratch. The UNIX 98 standard fcvt() apparently does not output scientific notation so you would have to implement it yourself, but I don't think it would be hard.

Install:

gacutil -i "path_to_the_assembly"

View:

Open in Windows Explorer folder

• .NET 1.0 - NET 3.5: c:\windows\assembly (%systemroot%\assembly)
• .NET 4.x: %windir%\Microsoft.NET\assembly

OR gacutil –l

When you are going to install an assembly you have to specify where gacutil can find it, so you have to provide a full path as well. But when an assembly already is in GAC - gacutil know a folder path so it just need an assembly name.

On Linux, the symlink /proc/<pid>/exe has the path of the executable. Use the command readlink -f /proc/<pid>/exe to get the value.

On AIX, this file does not exist. You could compare cksum <actual path to binary> and cksum /proc/<pid>/object/a.out.

The correct answer is usually to use require, but in a few cases it's not possible.

The following code will do the trick, but use it with care:

var fs = require('fs');
var vm = require('vm');
var includeInThisContext = function(path) {
    var code = fs.readFileSync(path);
    vm.runInThisContext(code, path);
}.bind(this);
includeInThisContext(__dirname+"/models/car.js");

Relying on compiler optimizations is fragile. The benchmarks linked in the accepted answer and numbers given by Antoine-tran are not to be trusted. Andrew Hare makes the mistake of including a call to repr in his methods. That slows all the methods equally but obscures the real penalty in constructing the string.

Use join. It's very fast and more robust.

In my case, I have a PHP web application being served by Apache2 within the docker container that connects to a MYSQL backend database. Larry Cai's solution worked with minor modifications. I created a entrypoint.sh file within which I am managing my services. I think creating an entrypoint.sh when you have more than one command to execute when your container starts up is a cleaner way to bootstrap docker.

I am using project is not Spring or spring boot based application. I have multiple subprojects and they are nested one within another. The answers shown here supports on first level of subproject. If I added another sub project for source code attachement, it is not allowing me saying folder already exists error.

Looks like eclipse is out dated IDE. I am using the latest version of Eclipse version 2015-2019. It is killing all my time.

My intension is run the application in debug mode navigate through the sub projects which are added as external dependencies (non modifiable).

A minor modification like below worked for me when using it from within perl and system() call:

sftp {user}@{host} <<< $'put {local_file_path} {remote_file_path}'

As others have said, the minumum/maximum values the column can store and how much storage it takes in bytes is only defined by the type, not the length.

A lot of these answers are saying that the (11) part only affects the display width which isn't exactly true, but mostly.

A definition of int(2) with no zerofill specified will:

• still accept a value of 100
• still display a value of 100 when output (not 0 or 00)
• the display width will be the width of the largest value being output from the select query.

The only thing the (2) will do is if zerofill is also specified:

• a value of 1 will be shown 01.
• When displaying values, the column will always have a width of the maximum possible value the column could take which is 10 digits for an integer, instead of the miniumum width required to display the largest value that column needs to show for in that specific select query, which could be much smaller.
• The column can still take, and show a value exceeding the length, but these values will not be prefixed with 0s.

The best way to see all the nuances is to run:

CREATE TABLE `mytable` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `int1` int(10) NOT NULL,
    `int2` int(3) NOT NULL,
    `zf1` int(10) ZEROFILL NOT NULL,
    `zf2` int(3) ZEROFILL NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO `mytable` 
(`int1`, `int2`, `zf1`, `zf2`) 
VALUES
(10000, 10000, 10000, 10000),
(100, 100, 100, 100);

select * from mytable;

which will output:

+----+-------+-------+------------+-------+
| id | int1  | int2  | zf1        | zf2   |
+----+-------+-------+------------+-------+
|  1 | 10000 | 10000 | 0000010000 | 10000 |
|  2 |   100 |   100 | 0000000100 |   100 |

In Python 3.6 the fastest way is still the WouterOvermeire one. Kikohs' proposal is slower than the other two options.

import timeit

setup = '''
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.randint(32, 120, 100000).reshape(50000,2),columns=list('AB'))
df['A'] = df['A'].apply(chr)
'''

timeit.Timer('dict(zip(df.A,df.B))', setup=setup).repeat(7,500)
timeit.Timer('pd.Series(df.A.values,index=df.B).to_dict()', setup=setup).repeat(7,500)
timeit.Timer('df.set_index("A").to_dict()["B"]', setup=setup).repeat(7,500)

Results:

1.1214002349999777 s  # WouterOvermeire
1.1922008498571748 s  # Jeff

I know the question is asking about your "csv" package implementation, but for your information, there are options that are much simpler — numpy, for instance.

import numpy as np
np.savetxt('data.csv', (col1_array, col2_array, col3_array), delimiter=',')

(This answer posted 6 years later, for posterity's sake.)

In a different case similar to what you're asking about, say you have two columns like this:

names = ['Player Name', 'Foo', 'Bar']
scores = ['Score', 250, 500]

You could save it like this:

np.savetxt('scores.csv', [p for p in zip(names, scores)], delimiter=',', fmt='%s')

scores.csv would look like this:

Player Name,Score
Foo,250
Bar,500

JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm page.

One idea is to let the the browser know that it should redirect by adding a redirect variable to to the resulting object and checking for it in JQuery:

$(document).ready(function(){ 
    jQuery.ajax({ 
        type: "GET", 
        url: "populateData.htm", 
        dataType:"json", 
        data:"userId=SampleUser", 
        success:function(response){ 
            if (response.redirect) {
                window.location.href = response.redirect;
            }
            else {
                // Process the expected results...
            }
        }, 
     error: function(xhr, textStatus, errorThrown) { 
            alert('Error!  Status = ' + xhr.status); 
         } 

    }); 
}); 

You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1") and in JQuery you do on success(!):

//....
        success:function(response){ 
            if (response.getResponseHeader('REQUIRES_AUTH') === '1'){ 
                window.location.href = 'login.htm'; 
            }
            else {
                // Process the expected results...
            }
        }
//....

Hope that helps.

My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.

if you have an __init__.py in an upper folder, you can initialize the import as import file/path as alias in that init file. Then you can use it on lower scripts as:

import alias

Since you're running Ubuntu, your system crontab is located at /etc/crontab.

As the root user (or using sudo), you can simply edit this file and specify the user that should run this command. Here is the format of entries in the system crontab and how you should enter your command:

# m h dom mon dow user  command
*/1 * * * * www-data php5 /var/www/web/includes/crontab/queue_process.php >> /var/www/web/includes/crontab/queue.log 2>&1

Of course the permissions for your php script and your log file should be set so that the www-data user has access to them.

This is because findViewById() searches in the activity_main layout, while the button is located in the fragment's layout fragment_main.

Move that piece of code in the onCreateView() method of the fragment:

//...

View rootView = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button)rootView.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        onButtonClick((Button) view);
    }

tl;dr:

concat and append currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True to silence it. In the future the default will change to not sort, so it's best to specify either sort=True or False now, or better yet ensure that your non-concatenation indices match.

The warning is new in pandas 0.23.0:

In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned, link.

More information from linked very old github issue, comment by smcinerney :

When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.

This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.

After some time the parameter sort was implemented in pandas.concat and DataFrame.append:

sort : boolean, default None

Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.

Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.

This has no effect when join='inner', which already preserves the order of the non-concatenation axis.

So if both DataFrames have the same columns in the same order, there is no warning and no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])

print (pd.concat([df1, df2]))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort is explicitly set (sort=None is the default value):

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=True))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=False))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a and b from df1 with a and b from df2 in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.

Lastly, if you pass sort=True, columns are sorted alphanumerically. If sort=False and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]}, 
                    columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]}, 
                    columns=['c','b','a','d'])

print (pd.concat([df1, df2]))

                                                       .append(placement_by_video_summary_new, sort=True)
                                                       .sort_index()

If you use log without base it uses e.

From the comment

Return the logarithm of x to the given base.
If the base not specified, returns the natural logarithm (base e) of x.

Therefor you have to use:

import math
print( math.log(1.5, 10))

Either:

public static string ByteArrayToString(byte[] ba)
{
  StringBuilder hex = new StringBuilder(ba.Length * 2);
  foreach (byte b in ba)
    hex.AppendFormat("{0:x2}", b);
  return hex.ToString();
}

or:

public static string ByteArrayToString(byte[] ba)
{
  return BitConverter.ToString(ba).Replace("-","");
}

There are even more variants of doing it, for example here.

The reverse conversion would go like this:

public static byte[] StringToByteArray(String hex)
{
  int NumberChars = hex.Length;
  byte[] bytes = new byte[NumberChars / 2];
  for (int i = 0; i < NumberChars; i += 2)
    bytes[i / 2] = Convert.ToByte(hex.Substring(i, 2), 16);
  return bytes;
}

Using Substring is the best option in combination with Convert.ToByte. See this answer for more information. If you need better performance, you must avoid Convert.ToByte before you can drop SubString.

Based on the answer from Luis, you can do something more like the default findBy method.

First, create a default repository class that is going to be used by all your entities.

/* $config is the entity manager configuration object. */
$config->setDefaultRepositoryClassName( 'MyCompany\Repository' );

Or you can edit this in config.yml

doctrine: orm: default_repository_class: MyCompany\Repository

Then:

<?php

namespace MyCompany;

use Doctrine\ORM\EntityRepository;

class Repository extends EntityRepository {

    public function findByNot( array $criteria, array $orderBy = null, $limit = null, $offset = null )
    {
        $qb = $this->getEntityManager()->createQueryBuilder();
        $expr = $this->getEntityManager()->getExpressionBuilder();

        $qb->select( 'entity' )
            ->from( $this->getEntityName(), 'entity' );

        foreach ( $criteria as $field => $value ) {
            // IF INTEGER neq, IF NOT notLike
            if($this->getEntityManager()->getClassMetadata($this->getEntityName())->getFieldMapping($field)["type"]=="integer") {
                $qb->andWhere( $expr->neq( 'entity.' . $field, $value ) );
            } else {
                $qb->andWhere( $expr->notLike( 'entity.' . $field, $qb->expr()->literal($value) ) );
            }
        }

        if ( $orderBy ) {

            foreach ( $orderBy as $field => $order ) {

                $qb->addOrderBy( 'entity.' . $field, $order );
            }
        }

        if ( $limit )
            $qb->setMaxResults( $limit );

        if ( $offset )
            $qb->setFirstResult( $offset );

        return $qb->getQuery()
            ->getResult();
    }

}

The usage is the same than the findBy method, example:

$entityManager->getRepository( 'MyRepo' )->findByNot(
    array( 'status' => Status::STATUS_DISABLED )
);

class test
{
    void message()
    {
        System.out.println("super class");
    }
}

class demo extends test
{
    int z;
    demo(int y)
    {
        super.message();
        z=y;
        System.out.println("re:"+z);
    }
}
class free{
    public static void main(String ar[]){
        demo d=new demo(6);
    }
}

The solution of Çagatay Gürtürk is nice but I experienced the same weirdness described by Luke The Obscure:

When ajax loading lasts too much (or mouse events are too quick) we have a .popover('show') and no .popover('hide') on a given element causing the popover to remain open.

I preferred this massive-pre-load solution, all popover-contents are loaded and events are handled by bootstrap like in normal (static) popovers.

$('.popover-ajax').each(function(index){

    var el=$(this);

    $.get(el.attr('data-load'),function(d){
        el.popover({content: d});       
    });     

});

The "problem" with the tabs is that they indent the text to fixed tab positions, typically multiples of 4 or 8 characters (depending on the console or editor displaying them). Your first filename is 7 chars, so the next tab stop after its end is at position 8. Your subsequent filenames however are 8 chars long, so the next tab stop is at position 12.

If you want to ensure that columns get nicely indented at the same position, you need to take into account the actual length of previous columns, and either modify the number of following tabs, or pad with the required number of spaces instead. The latter can be achieved using e.g. System.out.printf with an appropriate format specification (e.g. "%1$13s" specifies a minimum width of 13 characters for displaying the first argument as a string).

svn cat takes a revision arg too!

svn cat -r 175 mydir/myfile > mydir/myfile

Register an out parameter for the stored procedure, and set the value based on @@ROWCOUNT if using SQL Server. Use SQL%ROWCOUNT if you are using Oracle.

Mind that if you have multiple INSERT/UPDATE/DELETE, you'll need a variable to store the result from @@ROWCOUNT for each operation.

You can set this bookmarklet in your "Bookmarks Bar" in order to have Firebug lite always available in Chrome/Chromium browser (put this as the URL):

javascript:var firebug=document.createElement('script');firebug.setAttribute('src','http://getfirebug.com/releases/lite/1.2/firebug-lite-compressed.js');document.body.appendChild(firebug);(function(){if(window.firebug.version){firebug.init();}else{setTimeout(arguments.callee);}})();void(firebug);

The first answer is good for understanding how it works. But I wanted to understand how I should be using it in practice.

SUMMARY

• for moderately imbalanced data WITHOUT noise, there is not much of a difference in applying class weights
• for moderately imbalanced data WITH noise and strongly imbalanced, it is better to apply class weights
• param class_weight="balanced" works decent in the absence of you wanting to optimize manually
• with class_weight="balanced" you capture more true events (higher TRUE recall) but also you are more likely to get false alerts (lower TRUE precision)
  • as a result, the total % TRUE might be higher than actual because of all the false positives
  • AUC might misguide you here if the false alarms are an issue
• no need to change decision threshold to the imbalance %, even for strong imbalance, ok to keep 0.5 (or somewhere around that depending on what you need)

NB

The result might differ when using RF or GBM. sklearn does not have class_weight="balanced" for GBM but lightgbm has LGBMClassifier(is_unbalance=False)

Firstly make sure that you have installed python 2.7 or higher

Open Command Prompt as administrator and change directory to python and then change directory to Scripts by typing cd Scripts then type pip.exe and now you can install modules Step by Step:

• Open Cmd

• type in "cd \" and then enter

• type in "cd python2.7" and then enter

Note that my python version is 2.7 so my directory is that so use your python folder here...

• type in "cd Scripts" and enter

• Now enter this "pip.exe"

• Now it prompts you to install modules

Try this one:
Add itemizedOverlay class:

public class AndroidGoogleMapsActivity extends MapActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Displaying Zooming controls
        MapView mapView = (MapView) findViewById(R.id.mapview);
        mapView.setBuiltInZoomControls(true);


        MapController mc = mapView.getController();
        double lat = Double.parseDouble("48.85827758964043");
        double lon = Double.parseDouble("2.294543981552124");
        GeoPoint geoPoint = new GeoPoint((int)(lat * 1E6), (int)(lon * 1E6));
        mc.animateTo(geoPoint);
        mc.setZoom(15);
        mapView.invalidate(); 


        /**
         * Placing Marker
         * */
        List<Overlay> mapOverlays = mapView.getOverlays();
        Drawable drawable = this.getResources().getDrawable(R.drawable.mark_red);
        AddItemizedOverlay itemizedOverlay = 
             new AddItemizedOverlay(drawable, this);


        OverlayItem overlayitem = new OverlayItem(geoPoint, "Hello", "Sample Overlay item");

        itemizedOverlay.addOverlay(overlayitem);
        mapOverlays.add(itemizedOverlay);

    }

    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }
}

For each works with JQuery as in

$(<selector>).each(function() {
   //this points to item
   alert('<msg>');
});

JQuery also, for a popup, has in the UI library a dialog widget: http://jqueryui.com/demos/dialog/

Check it out, works really well.

HTH.

Depending on how your layout works, you might get away with setting the background on the <html> element, which is always at least the height of the viewport.

CREATE PROCEDURE sp_deleteUserDetails
    @Email varchar(255)
AS
    declare @tempRegId as int
    Delete UserRegistration where Email=@Email  
    set @tempRegId = (select Id from UserRegistration where Email = @Email)
    Delete UserProfile where RegID=@tempRegId

RETURN 0

This works for me on the webpack.config.js

    new webpack.ProvidePlugin({
        $: 'jquery',
        jQuery: 'jquery',
        'window.jQuery': 'jquery'
    }),

in another javascript or into HTML add:

global.jQuery = require('jquery');

Use json_decode to convert the JSON string to a PHP array, then use normal PHP array functions on it.

$json = '[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]';
$data = json_decode($json);

var_dump($data[0]['var1']); // outputs '9'

I've modified your plunker to get it working via angular-xeditable:

http://plnkr.co/edit/xUDrOS?p=preview

It is common solution for inline editing - you creale hyperlinks with editable-text directive that toggles into <input type="text"> tag:

<a href="#" editable-text="bday.name" ng-click="myform.$show()" e-placeholder="Name">
    {{bday.name || 'empty'}}
</a>

For date I used editable-date directive that toggles into html5 <input type="date">.

Open firewall settings. Then search for something like - Allow program or feature to allow through firewall. If in the list World Wide Web services (HTTP) is unchecked, check it and restart the system.

Our machine is all set to accept inbound requests.

A subquery is a select statement that is embedded in a clause of another select statement.

EX:

select ename, sal 
from emp  where sal > (select sal 
                       from emp where ename ='FORD');

A Correlated subquery is a subquery that is evaluated once for each row processed by the outer query or main query. Execute the Inner query based on the value fetched by the Outer query all the values returned by the main query are matched. The INNER Query is driven by the OUTER Query.

Ex:

select empno,sal,deptid 
from emp e 
where sal=(select avg(sal) 
           from emp where deptid=e.deptid);

DIFFERENCE

The inner query executes first and finds a value, the outer query executes once using the value from the inner query (subquery)

Fetch by the outer query, execute the inner query using the value of the outer query, use the values resulting from the inner query to qualify or disqualify the outer query (correlated)

There are several ways to do plots in R; lattice is one of them, and always a reasonable solution, +1 to @agstudy. If you want to do this in base graphics, you could try the following:

Reasonstats <- read.table(text="Category         Reason  Species
                                 Decline        Genuine       24
                                Improved        Genuine       16
                                Improved  Misclassified       85
                                 Decline  Misclassified       41
                                 Decline      Taxonomic        2
                                Improved      Taxonomic        7
                                 Decline        Unclear       41
                                Improved        Unclear      117", header=T)

ReasonstatsDec <- Reasonstats[which(Reasonstats$Category=="Decline"),]
ReasonstatsImp <- Reasonstats[which(Reasonstats$Category=="Improved"),]
Reasonstats3   <- cbind(ReasonstatsImp[,3], ReasonstatsDec[,3])
colnames(Reasonstats3) <- c("Improved", "Decline")
rownames(Reasonstats3) <- ReasonstatsImp$Reason

windows()
  barplot(t(Reasonstats3), beside=TRUE, ylab="number of species", 
          cex.names=0.8, las=2, ylim=c(0,120), col=c("darkblue","red"))
  box(bty="l")

Here's what I did: I created a matrix with two columns (because your data were in columns) where the columns were the species counts for Decline and for Improved. Then I made those categories the column names. I also made the Reasons the row names. The barplot() function can operate over this matrix, but wants the data in rows rather than columns, so I fed it a transposed version of the matrix. Lastly, I deleted some of your arguments to your barplot() function call that were no longer needed. In other words, the problem was that your data weren't set up the way barplot() wants for your intended output.

If you would like to show it in a new window, you could use Tkinter + PIL library, like so:

import tkinter as tk
from PIL import ImageTk, Image

def show_imge(path):
    image_window = tk.Tk()
    img = ImageTk.PhotoImage(Image.open(path))
    panel = tk.Label(image_window, image=img)
    panel.pack(side="bottom", fill="both", expand="yes")
    image_window.mainloop()

This is a modified example that can be found all over the web.

It is ALWAYS preferable to use const, instead of #define. That's because const is treated by the compiler and #define by the preprocessor. It is like #define itself is not part of the code (roughly speaking).

Example:

#define PI 3.1416

The symbolic name PI may never be seen by compilers; it may be removed by the preprocessor before the source code even gets to a compiler. As a result, the name PI may not get entered into the symbol table. This can be confusing if you get an error during compilation involving the use of the constant, because the error message may refer to 3.1416, not PI. If PI were defined in a header file you didn’t write, you’d have no idea where that 3.1416 came from.

This problem can also crop up in a symbolic debugger, because, again, the name you’re programming with may not be in the symbol table.

Solution:

const double PI = 3.1416; //or static const...

If you want to update/replace the values of first dataframe df1 with the values of second dataframe df2. you can do it by following steps —

Step 1: Set index of the first dataframe (df1)

df1.set_index('id')

Step 2: Set index of the second dataframe (df2)

df2.set_index('id')

and finally update the dataframe using the following snippet —

df1.update(df2)

If you're trying this with GitHub, you can do this with your SSH entered:

git clone https://[email protected]/username/repository

Contains(s2) is many times (in my computer 10 times) faster than IndexOf(s2) because Contains uses StringComparison.Ordinal that is faster than the culture sensitive search that IndexOf does by default (but that may change in .net 4.0 http://davesbox.com/archive/2008/11/12/breaking-changes-to-the-string-class.aspx).

Contains has exactly the same performance as IndexOf(s2,StringComparison.Ordinal) >= 0 in my tests but it's shorter and makes your intent clear.

i was trying trying to GRANT read-only privileges to a particular table to a user called walters-ro. So when i ran the sql command # GRANT SELECT ON table_name TO walters-ro; --- i got the following error..`syntax error at or near “-”

The solution to this was basically putting the user_name into double quotes since there is a dash(-) between the name.

# GRANT SELECT ON table_name TO "walters-ro";

That solved the problem.

I did that with helping from this question

jquery get querystring from URL

so let see how we will use this function

// Read a page's GET URL variables and return them as an associative array.
function getUrlVars()
{
    var vars = [], hash;
    var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
    for(var i = 0; i < hashes.length; i++)
    {
        hash = hashes[i].split('=');
        vars.push(hash[0]);
        vars[hash[0]] = hash[1];
    }
    return vars;
}

and now just use it in Ajax call

"ajax": {
    url: '/Departments/GetAllDepartments/',                     
    type: 'GET',                       
    dataType: 'json',                       
    data: getUrlVars()// here is the tricky part
},

thats all, but if you want know how to use this function or not send all the query string parameters back to actual answer

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

You can try out this one as well as. Because this worked for me and it's simple.

<style>
    <%@ include file="/css/style.css" %>
</style>

In Swift you can override the accessor of the highlighted (or selected) property rather than overriding the setHighlighted method

override var highlighted: Bool {
        get {
            return super.highlighted
        }
        set {
            if newValue {
                backgroundColor = UIColor.blackColor()
            }
            else {
                backgroundColor = UIColor.whiteColor()
            }
            super.highlighted = newValue
        }
    }

I know this is very late, but maybe this will help someone else.

I use a Cancel button to return to the referring url. In the View, try adding this:

@{
  ViewBag.Title = "Page title";
  Layout = "~/Views/Shared/_Layout.cshtml";

  if (Request.UrlReferrer != null)
  {
    string returnURL = Request.UrlReferrer.ToString();
    ViewBag.ReturnURL = returnURL;
  }
}

Then you can set your buttons href like this:

<a href="@ViewBag.ReturnURL" class="btn btn-danger">Cancel</a>

Other than that, the update by Jason Enochs works great!

The RecyclerView takes care of adding, removing, and re-ordering animations!

This simple AndroidStudio project features a RecyclerView. take a look at the commits:

1. commit of the classic Hello World Android app
2. commit, adding a RecyclerView to the project (content not dynamic)
3. commit, adding functionality to modify content of RecyclerView at runtime (but no animations)
4. and finally...commit adding animations to the RecyclerView

Just stumbled upon this and thought I would suggest my solution. I typically like to use the built in functionality of assigning a range to an multi-dim array (I guess it's also the JS Programmer in me).

I frequently write code like this:

Sub arrayBuilder()

myarray = Range("A1:D4")

'unlike most VBA Arrays, this array doesn't need to be declared and will be automatically dimensioned

For i = 1 To UBound(myarray)

    For j = 1 To UBound(myarray, 2)

    Debug.Print (myarray(i, j))

    Next j

Next i

End Sub

Assigning ranges to variables is a very powerful way to manipulate data in VBA.

If you have one or more EditTexts inside of a recyclerview items, disable the autofocus of these, putting this configuration in the parent view of recyclerview:

android:focusable="true"
android:focusableInTouchMode="true"

I had this issue when I started another activity launched from a recyclerview item, when I came back and set an update of one field in one item with notifyItemChanged(position) the scroll of RV moves, and my conclusion was that, the autofocus of EditText Items, the code above solved my issue.

best.

It's usually \t in command-line interfaces, which will convert the char \t into the whitespace tab character.

For example, hello\talex -> hello--->alex.

package net.itempire.virtualapp;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Base64;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;

public class BaseActivity extends AppCompatActivity {
EditText editText;
TextView textView;
TextView textView2;
TextView textView3;
TextView textView4;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_base);
        editText=(EditText)findViewById(R.id.edt);
        textView=(TextView) findViewById(R.id.tv1);
        textView2=(TextView) findViewById(R.id.tv2);
        textView3=(TextView) findViewById(R.id.tv3);
        textView4=(TextView) findViewById(R.id.tv4);
        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
             textView2.setText(Base64.encodeToString(editText.getText().toString().getBytes(),Base64.DEFAULT));
            }
        });

        textView3.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                textView4.setText(new String(Base64.decode(textView2.getText().toString(),Base64.DEFAULT)));

            }
        });


    }

Use Google Search Operators to find it for you

search google with the below code..

change domain.com to the domain you want to find the sitemap. this should list all the xml files listed for the given domain.. including all sitemaps :)

If you look in your installation's bin directory you will see catalina.sh or .bat scripts. If you look in these you will see that they run a setenv.sh or setenv.bat script respectively, if it exists, to set environment variables. The relevant environment variables are described in the comments at the top of catalina.sh/bat. To use them create, for example, a file $CATALINA_HOME/bin/setenv.sh with contents

export JAVA_OPTS="-server -Xmx512m"

For Windows you will need, in setenv.bat, something like

set JAVA_OPTS=-server -Xmx768m

Original answer here

After you run startup.bat, you can easily confirm the correct settings have been applied provided you have turned @echo on somewhere in your catatlina.bat file (a good place could be immediately after echo Using CLASSPATH: "%CLASSPATH%"):

ng-init is a directive that can be placed inside div's, span's, whatever, whereas onload is an attribute specific to the ng-include directive that functions as an ng-init. To see what I mean try something like:

<span onload="a = 1">{{ a }}</span>
<span ng-init="b = 2">{{ b }}</span>

You'll see that only the second one shows up.

An isolated scope is a scope which does not prototypically inherit from its parent scope. In laymen's terms if you have a widget that doesn't need to read and write to the parent scope arbitrarily then you use an isolate scope on the widget so that the widget and widget container can freely use their scopes without overriding each other's properties.

Here is brilliant quotes from Apple Developer Forums described delicious details:

unowned vs unowned(safe) vs unowned(unsafe)

unowned(safe) is a non-owning reference that asserts on access that the object is still alive. It's sort of like a weak optional reference that's implicitly unwrapped with x! every time it's accessed. unowned(unsafe) is like __unsafe_unretained in ARC—it's a non-owning reference, but there's no runtime check that the object is still alive on access, so dangling references will reach into garbage memory. unowned is always a synonym for unowned(safe) currently, but the intent is that it will be optimized to unowned(unsafe) in -Ofast builds when runtime checks are disabled.

unowned vs weak

unowned actually uses a much simpler implementation than weak. Native Swift objects carry two reference counts, and unowned references bump the unowned reference count instead of the strong reference count. The object is deinitialized when its strong reference count reaches zero, but it isn't actually deallocated until the unowned reference count also hits zero. This causes the memory to be held onto slightly longer when there are unowned references, but that isn't usually a problem when unowned is used because the related objects should have near-equal lifetimes anyway, and it's much simpler and lower-overhead than the side-table based implementation used for zeroing weak references.

Update: In modern Swift weak internally uses the same mechanism as unowned does. So this comparison is incorrect because it compares Objective-C weak with Swift unonwed.

Reasons

What is the purpose of keeping the memory alive after owning references reach 0? What happens if code attempts to do something with the object using an unowned reference after it is deinitialized?

The memory is kept alive so that its retain counts are still available. This way, when someone attempts to retain a strong reference to the unowned object, the runtime can check that the strong reference count is greater than zero in order to ensure that it is safe to retain the object.

What happens to owning or unowned references held by the object? Is their lifetime decoupled from the object when it is deinitialized or is their memory also retained until the object is deallocated after the last unowned reference is released?

All resources owned by the object are released as soon as the object's last strong reference is released, and its deinit is run. Unowned references only keep the memory alive—aside from the header with the reference counts, its contents is junk.

Excited, huh?

The one thing I'd avoid is doing DOM operations in a loop to avoid repeated re-renderings of the page.

var firstSelect = document.getElementById('first select elements id'),
    secondSelect = document.getElementById('second select elements id'),
    optionsHTML = [],
    i = 12;

for (; i < 100; i += 1) {
  optionsHTML.push("<option value=\"Age" + i + "\">Age" + i + "</option>";
}

firstSelect.innerHTML = optionsHTML.join('\n');
secondSelect.innerHTML = optionsHTML.join('\n');

Edit: removed the function to show how you can just assign the html you've built up to another select element - thus avoiding the unnecessary looping by repeating the function call.

This is the only thing that I found to work

-(void) testHTTPS {
    AFSecurityPolicy *securityPolicy = [[AFSecurityPolicy alloc] init];
    [securityPolicy setAllowInvalidCertificates:YES];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager setSecurityPolicy:securityPolicy];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

    [manager GET:[NSString stringWithFormat:@"%@", HOST] parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
        NSLog(@"%@", string);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
}

You don't tend to execute the make file itself, rather you execute make, giving it the make file as an argument:

make -f pax.mk

If your make file is actually one of the standard names (like makefile or Makefile), you don't even need to specify it. It'll be picked up by default (if you have more than one of these standard names in your build directory, you better look up the make man page to see which takes precedence).

in devices which has Android 4.3 and above you should follow these steps:

How to enable Developer Options:

Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.

In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.

JavaScript does not offer this functionality natively. And I doubt you could even create this type of functionality. For example:

var Bobby = {name: "Bobby"};
var Dad = {name: "Dad", children: [ Bobby ]};
var Mom = {name: "Mom", children: [ Bobby ]};

Who does Bobby belong to?

In your bean definition, make sure to include "searchSystemEnvironment" and set it to "true". And if you're using it to build a path to a file, specify it as a file:/// url.

So for example, if you have a config file located in

/testapp/config/my.app.config.properties

then set an environment variable like so:

MY_ENV_VAR_PATH=/testapp/config

and your app can load the file using a bean definition like this:

e.g.

<bean class="org.springframework.web.context.support.ServletContextPropertyPlaceholderConfigurer">
    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
    <property name="searchSystemEnvironment" value="true" />
    <property name="searchContextAttributes" value="true" />
    <property name="contextOverride" value="true" />
    <property name="ignoreResourceNotFound" value="true" />
    <property name="locations">
        <list>
            <value>file:///${MY_ENV_VAR_PATH}/my.app.config.properties</value>
        </list>
    </property>
</bean>

Here's what I do:

Generate a hidden iFrame with the data you would like to post. Since you still control that iFrame, same origin does not apply. Then submit the form in that iFrame to the ssl page. The ssl page then redirects to a non-ssl page with status messages. You have access to the iFrame.

Use realpath

$ realpath example.txt
/home/username/example.txt

I have given the comparison of all three discussed above.

Using values

%timeit df['value'] = df['a'].values % df['c'].values

139 µs ± 1.91 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)

Without values

%timeit df['value'] = df['a']%df['c'] 

216 µs ± 1.86 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Apply function

%timeit df['Value'] = df.apply(lambda row: row['a']%row['c'], axis=1)

474 µs ± 5.07 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

you can also use VSCommands 2010 to run as different user:

The OP's code snippet clearly uses the correct comment markup but CSS can break in a progressive way — so, if there's a syntax error, everything after that is likely to fail. A couple times I've relied on trustworthy sources that supplied incorrect comment markup that broke my style sheet. Since the OP provided just a small section of their code, I'd suggest the following:

Make sure all of your CSS comments use this markup /* ... */ -- which is the correct comment markup for css according to MDN

Validate your css with a linter or a secure online validator. Here's one by W3

More info: I went to check the latest recommended media query breakpoints from bootstrap 4 and ended up copying the boiler plate straight from their docs. Almost every code block was labeled with javascript-style comments //, which broke my code — and gave me only cryptic compile errors with which to troubleshoot, which went over my head at the time and caused me sadness.

IntelliJ text editor allowed me to comment out specific lines of css in a LESS file using the ctrl+/ hotkey which was great except it inserts // by default on unrecognized file types. It isn't freeware and less is fairly mainstream so I trusted it and went with it. That broke my code. There's a preference menu for teaching it the correct comment markup for each filetype.

IF is used to select the field, then the LIKE clause is placed after it:

SELECT  `id` ,  `naam` 
FROM  `klanten` 
WHERE IF(`email` != '', `email`, `email2`) LIKE  '%@domain.nl%'

Try this code, it helped me!

$('.slider-selector').not('.slick-initialized').slick({
  dots: true,
  arrows: false,
  setPosition: true
});

I was facing the same issue in bitbucket, and this worked for me:

No mention of Merge?

DataSet newdataset = new DataSet();

newdataset.Merge( olddataset.Tables[0].Select( filterstring, sortstring ));

if your not satisfied with the answers above then use this

    * {margin: 0;padding: 0;}

    html
    {
        height: 100%;
    }

    body
    {

        background-repeat: no-repeat;
        background-position: center center;
        background-size: 80%;
    }

It could be dependent upon what is supported by the module you are trying to compile. If your makefile is generated by using autotools, use:

--prefix=<myinstalldir>

when running the ./configure

some packages allow you to also override when running:

make prefix=<myinstalldir>

however, if your not using ./configure, only way to know for sure is to open up the makefile and check. It should be one of the first few variables at the top.

Try /E

I am now able to successfully build. Not sure exactly which step "fixed" things, but this was the sequence:

• Tried automatic signing again. No go, so reverted to manual.
• After reverting, I had no Eligible Profiles, all were ineligible. Strange.
• I created a new certificate and profile, imported both. This too was "ineligible".
• Removed the iOS platform and re-added it. I had tried this previously without luck.
• After doing this, Xcode on its own defaulted to automatic signing. And this worked! Success!

While I am not sure exactly which parts were necessary, I think the previous certificates were the problem. I hate Xcode :(

Thanks for help.

For tomcat you can increase the permGem space by using

 -XX:MaxPermSize=128m

For this you need to create (if not already exists) a file named setenv.sh in tomcat/bin folder and include following line in it

   export JAVA_OPTS="-XX:MaxPermSize=128m"

There are many ways to create re-usable objects like this in JavaScript. Mozilla have a nice introduction here:

• https://developer.mozilla.org/en-US/docs/JavaScript/Introduction_to_Object-Oriented_JavaScript

The following will work in your example:

function Foo(){
    this.bar = function (){
        alert("Hello World!");
    }
}

myFoo = new Foo();
myFoo.bar(); // Hello World?????????????????????????????????

You can pre-fetch your data by using Resolvers in Angular2+, Resolvers process your data before your Component fully be loaded.

There are many cases that you want to load your component only if there is certain thing happening, for example navigate to Dashboard only if the person already logged in, in this case Resolvers are so handy.

Look at the simple diagram I created for you for one of the way you can use the resolver to send the data to your component.

Applying Resolver to your code is pretty simple, I created the snippets for you to see how the Resolver can be created:

import { Injectable } from '@angular/core';
import { Router, Resolve, RouterStateSnapshot, ActivatedRouteSnapshot } from '@angular/router';
import { MyData, MyService } from './my.service';

@Injectable()
export class MyResolver implements Resolve<MyData> {
  constructor(private ms: MyService, private router: Router) {}

  resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Promise<MyData> {
    let id = route.params['id'];

    return this.ms.getId(id).then(data => {
      if (data) {
        return data;
      } else {
        this.router.navigate(['/login']);
        return;
      }
    });
  }
}

and in the module:

import { MyResolver } from './my-resolver.service';

@NgModule({
  imports: [
    RouterModule.forChild(myRoutes)
  ],
  exports: [
    RouterModule
  ],
  providers: [
    MyResolver
  ]
})
export class MyModule { }

and you can access it in your Component like this:

/////
 ngOnInit() {
    this.route.data
      .subscribe((data: { mydata: myData }) => {
        this.id = data.mydata.id;
      });
  }
/////

And in the Route something like this (usually in the app.routing.ts file):

////
{path: 'yourpath/:id', component: YourComponent, resolve: { myData: MyResolver}}

Correct answer is:

$.each(lines, function(lineNo, line) {
                    var items = line.split(',');
                    var data = {};
                    $.each(items, function(itemNo, item) {
                        if (itemNo === 0) {
                            data.name = item;
                        } else {
                            data.y = parseFloat(item);
                        }
                    });
                    options.series[0].data.push(data);
                    data = {};
                });

You need to flush the 'data' array.

data = {};

While it's not currently possible with the script tag, it is possible with an iframe if it's from the same domain.

<iframe
id="mySpecialId"
src="/my/link/to/some.json"
onload="(()=>{if(!window.jsonData){window.jsonData={}}try{window.jsonData[this.id]=JSON.parse(this.contentWindow.document.body.textContent.trim())}catch(e){console.warn(e)}this.remove();})();"
onerror="((err)=>console.warn(err))();"
style="display: none;"
></iframe>

To use the above, simply replace the id and src attribute with what you need. The id (which we'll assume in this situation is equal to mySpecialId) will be used to store the data in window.jsonData["mySpecialId"].

In other words, for every iframe that has an id and uses the onload script will have that data synchronously loaded into the window.jsonData object under the id specified.

I did this for fun and to show that it's "possible' but I do not recommend that it be used.

Here is an alternative that uses a callback instead.

<script>
    function someCallback(data){
        /** do something with data */
        console.log(data);

    }
    function jsonOnLoad(callback){
        const raw = this.contentWindow.document.body.textContent.trim();
        try {
          const data = JSON.parse(raw);
          /** do something with data */
          callback(data);
        }catch(e){
          console.warn(e.message);
        }
        this.remove();
    }
</script>
<!-- I frame with src pointing to json file on server, onload we apply "this" to have the iframe context, display none as we don't want to show the iframe -->
<iframe src="your/link/to/some.json" onload="jsonOnLoad.apply(this, someCallback)" style="display: none;"></iframe>

Tested in chrome and should work in firefox. Unsure about IE or Safari.

Spring provides a very clean division between controllers, JavaBean models, and views.

The first line of every source file of your project must be the following:

#include <stdafx.h>

Another way:

export default class Archive extends React.Component { 

  saySomething = (something) => {
    console.log(something);
  }

  handleClick = (e) => {
    this.saySomething("element clicked");
  }

  componentDidMount() {
    this.saySomething("component did mount");
  }

  render() {
    return <button onClick={this.handleClick} value="Click me" />;
  }
}

In this format you don't need to use bind

Try this!

this.selectedObjectList = [{id:1}, {id:2}, {id:3}]
this.allObjectList = [{id:1}, {id:2}, {id:3}, {id:4}, {id:5}]
let newList = this.allObjectList.filter(e => this.selectedObjectList.find(a => e.id == a.id))
this.selectedObjectList = newList

Your can do it like this in short hands.

        int[,] values=new int[2,3]{{2,4,5},{4,5,2}};

        for (int i = 0; i < values.GetLength(0); i++)
        {
            for (int k = 0; k < values.GetLength(1); k++) {
                Console.Write(values[i,k]);
            }

            Console.WriteLine();
        }

I feel many of the answers here are lacking a creative component, very much needed for time travel computations. I present my solution for a temporal translation of 30 minutes.

(jsfiddle here)

function fluxCapacitor(n) {
    var delta,sigma=0,beta="ge";
    (function(K,z){

        (function(a,b,c){
            beta=beta+"tT";
            switch(b.shift()) {
                case'3':return z('0',a,c,b.shift(),1);
                case'0':return z('3',a,c,b.pop());
                case'5':return z('2',a,c,b[0],1);
                case'1':return z('4',a,c,b.shift());
                case'2':return z('5',a,c,b.pop());
                case'4':return z('1',a,c,b.pop(),1);
            }
        })(K.pop(),K.pop().split(''),K.pop());
    })(n.toString().split(':'),function(b,a,c,b1,gamma){
       delta=[c,b+b1,a];sigma+=gamma?3600000:0; 
       beta=beta+"im";
    });
    beta=beta+"e";
    return new Date (sigma+(new Date( delta.join(':')))[beta]());
}

To install more recent versions of OpenJDK, I use this. Example for OpenJDK 14:

brew info adoptopenjdk
brew tap adoptopenjdk/openjdk
brew cask install adoptopenjdk14

See https://github.com/AdoptOpenJDK/homebrew-openjdk for current info.

You want to replace the values in a dataset column, but you're getting an error like this:

invalid factor level, NA generated

Try this instead:

levels(dataframe$column)[levels(dataframe$column)=='old_value'] <- 'new_value'

Apparently you don't need to specify height at all! Which is great if it changes for some reason (you resize components or change font sizes).

I just followed this tutorial and everything worked: http://natashatherobot.com/ios-autolayout-scrollview/

(Side note: There is no need to implement viewDidLayoutSubviews unless you want to center the view, so the list of steps is even shorter).

Hope that helps!

This simplest ways is to add the "checked attribute.

<label for="tag_1">Tag 1</label>
<input type="checkbox" name="tag_1" id="tag_1" value="yes" 
    <?php if($tag_1_saved_value === 'yes') echo 'checked="checked"';?> />

Putting the code in a function, then using a decorator for timing is another option. (Source) The advantage of this method is that you define timer once and use it with a simple additional line for every function.

First, define timer decorator:

import functools
import time

def timer(func):
    @functools.wraps(func)
    def wrapper(*args, **kwargs):
        start_time = time.perf_counter()
        value = func(*args, **kwargs)
        end_time = time.perf_counter()
        run_time = end_time - start_time
        print("Finished {} in {} secs".format(repr(func.__name__), round(run_time, 3)))
        return value

    return wrapper

Then, use the decorator while defining the function:

@timer
def doubled_and_add(num):
    res = sum([i*2 for i in range(num)])
    print("Result : {}".format(res))

Let's try:

doubled_and_add(100000)
doubled_and_add(1000000)

Output:

Result : 9999900000
Finished 'doubled_and_add' in 0.0119 secs
Result : 999999000000
Finished 'doubled_and_add' in 0.0897 secs

Note: I'm not sure why to use time.perf_counter instead of time.time. Comments are welcome.

After struggling for some time, I think I found out quite simple solution.

Inspired by Robin Wilson I made this simple JS function (the original resizes both width and height, mine is just for the width):

 function changeFBPagePlugin() {
    var container_width = Number($('.fb-container').width()).toFixed(0);
    if (!isNaN(container_width)) {
        $(".fb-page").attr("data-width", container_width);
    }
    if (typeof FB !== 'undefined') {
        FB.XFBML.parse();
    }
};

It checks for the current width of the wrapping div and then puts the value inside fb-page div. The magic is done with FB.XFBML object, that is a part of Facebook SDK, which becomes available when you initialize the fb-page itself via window.fbAsyncInit

I bind my function to html body's onLoad and onResize:

<body onload="changeFBPagePlugin()" onresize="changeFBPagePlugin()">

On the page I have my fb-page plugin wrapped in another div that is used as reference:

<div class="fb-container"> 
    <div class="fb-page" ...stuff you need for FB page plugin... </div>
</div>

Finally the simple CSS for the wrapper to assure it stretches over the available space:

.fb-container {
    width: 95%;
    margin: 0px auto;
}

Putting all this together the results seem quite satisfying. Hopefuly this will help someone, although the question was posted quite a long time ago.

putting backslash "/" at the end of path to bin of mongodb solved my problem.

I am using Chrome version 21 with SQL 2008 R2 SP1 and none of the above fixes worked for me. Below is the code that did work, as with the other answers I added this bit of code to Append to "C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportManager\js\ReportingServices.js" (on the SSRS Server) :

//Fix to allow Chrome to display SSRS Reports
function pageLoad() { 
    var element = document.getElementById("ctl31_ctl09");
    if (element) 
    {
        element.style.overflow = "visible";         
    } 
}

The join() method allows one thread to wait for the completion of another.However, as with sleep, join is dependent on the OS for timing, so you should not assume that join will wait exactly as long as you specify.

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

Or alternatively if you have the XML in a string use the LoadXml method.

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>[email protected]</Email>
    </Company>
</Data>

Very late answer, but you can simply use:

import time
today = time.strftime("%Y-%m-%d")
# 2021-02-18

x = y = 5 is equivalent to x = (y = 5), because the assignment operators "group" right to left, which works. Meaning: assign 5 to y, leaving the number 5; and then assign that 5 to x.

This is not the same as (x = y) = 5, which doesn't work! Meaning: assign the value of y to x, leaving the value of y; and then assign 5 to, umm..., what exactly?

When you mix the different kinds of assignment operators, <- binds tighter than =. So x = y <- 5 is interpreted as x = (y <- 5), which is the case that makes sense.

Unfortunately, x <- y = 5 is interpreted as (x <- y) = 5, which is the case that doesn't work!

See ?Syntax and ?assignOps for the precedence (binding) and grouping rules.

Here is an example using ng-messages (available in angular 1.3) and a custom directive.

Validation message is displayed on blur for the first time user leaves the input field, but when he corrects the value, validation message is removed immediately (not on blur anymore).

JavaScript

myApp.directive("validateOnBlur", [function() {
    var ddo = {
        restrict: "A",
        require: "ngModel",
        scope: {},
        link: function(scope, element, attrs, modelCtrl) {
            element.on('blur', function () {
                modelCtrl.$showValidationMessage = modelCtrl.$dirty;
                scope.$apply();
            });
        }
    };
    return ddo;
}]);

HTML

<form name="person">
    <input type="text" ng-model="item.firstName" name="firstName" 
        ng-minlength="3" ng-maxlength="20" validate-on-blur required />
    <div ng-show="person.firstName.$showValidationMessage" ng-messages="person.firstName.$error">
        <span ng-message="required">name is required</span>
        <span ng-message="minlength">name is too short</span>
        <span ng-message="maxlength">name is too long</span>
    </div>
</form>

PS. Don't forget to download and include ngMessages in your module:

var myApp = angular.module('myApp', ['ngMessages']);

Using parameters in batch files: %0 and %9

Batch files can refer to the words passed in as parameters with the tokens: %0 to %9.

%0 is the program name as it was called.
%1 is the first command line parameter
%2 is the second command line parameter
and so on till %9.

parameters passed in on the commandline must be alphanumeric characters and delimited by spaces. Since %0 is the program name as it was called, in DOS %0 will be empty for AUTOEXEC.BAT if started at boot time.

Example:

Put the following command in a batch file called mybatch.bat:

@echo off
@echo hello %1 %2
pause

Invoking the batch file like this: mybatch john billy would output:

hello john billy

Get more than 9 parameters for a batch file, use: %*

The Percent Star token %* means "the rest of the parameters". You can use a for loop to grab them, as defined here:

http://www.robvanderwoude.com/parameters.php

Notes about delimiters for batch parameters

Some characters in the command line parameters are ignored by batch files, depending on the DOS version, whether they are "escaped" or not, and often depending on their location in the command line:

commas (",") are replaced by spaces, unless they are part of a string in 
double quotes

semicolons (";") are replaced by spaces, unless they are part of a string in 
double quotes

"=" characters are sometimes replaced by spaces, not if they are part of a 
string in double quotes

the first forward slash ("/") is replaced by a space only if it immediately 
follows the command, without a leading space

multiple spaces are replaced by a single space, unless they are part of a 
string in double quotes

tabs are replaced by a single space

leading spaces before the first command line argument are ignored

There is a JDK socket tutorial here, which covers both the server and client end. That looks exactly like what you want.

(from that tutorial) This sets up to read from an echo server:

    echoSocket = new Socket("taranis", 7);
    out = new PrintWriter(echoSocket.getOutputStream(), true);
    in = new BufferedReader(new InputStreamReader(
                                echoSocket.getInputStream()));

taking a stream of bytes and converts to strings via the reader and using a default encoding (not advisable, normally).

Error handling and closing sockets/streams omitted from the above, but check the tutorial.
