Programs & Examples On #Vertices

The best way to implement it using matplotlib.pyplot.bar(range, height, tick_label) where the range provides scalar values for the positioning of the corresponding bar in the graph. tick_label does the same work as xticks(). One can replace it with an integer also and use multiple plt.bar(integer, height, tick_label). For detailed information please refer the documentation.

import matplotlib.pyplot as plt

data = {'apple': 67, 'mango': 60, 'lichi': 58}
names = list(data.keys())
values = list(data.values())

#tick_label does the some work as plt.xticks()
plt.bar(range(len(data)),values,tick_label=names)
plt.savefig('bar.png')
plt.show()

Additionally the same plot can be generated without using range(). But the problem encountered was that tick_label just worked for the last plt.bar() call. Hence xticks() was used for labelling:

data = {'apple': 67, 'mango': 60, 'lichi': 58}
names = list(data.keys())
values = list(data.values())
plt.bar(0,values[0],tick_label=names[0])
plt.bar(1,values[1],tick_label=names[1])
plt.bar(2,values[2],tick_label=names[2])
plt.xticks(range(0,3),names)
plt.savefig('fruit.png')
plt.show()

You can use

Queue thequeue = new linkedlist();

or

Queue thequeue = new Priorityqueue();

Reason: Queue is an interface. So you can instantiate only its concrete subclass.

As other people have mentioned, ArrayList has a constructor that takes a collection of items, and adds all of them. Here's the documentation:

http://java.sun.com/javase/6/docs/api/java/util/ArrayList.html#ArrayList%28java.util.Collection%29

So you need to do:

ArrayList<MyNode> myNodeList = new ArrayList<MyNode>(this.getVertices());

However, in another comment you said that was giving you a compiler error. It looks like your class MyGraph is a generic class. And so getVertices() actually returns type V, not type myNode.

I think your code should look like this:

public V getNode(int nodeId){
        ArrayList<V> myNodeList = new ArrayList<V>(this.getVertices());
        return myNodeList(nodeId);
}

But, that said it's a very inefficient way to extract a node. What you might want to do is store the nodes in a binary tree, then when you get a request for the nth node, you do a binary search.

(del can be your friend, as it marks objects as being deletable when there no other references to them. Now, often the CPython interpreter keeps this memory for later use, so your operating system might not see the "freed" memory.)

Maybe you would not run into any memory problem in the first place by using a more compact structure for your data. Thus, lists of numbers are much less memory-efficient than the format used by the standard array module or the third-party numpy module. You would save memory by putting your vertices in a NumPy 3xN array and your triangles in an N-element array.

DFS APPROACH WITH A CONDITION(parent != next node) Let's see the code and then understand what's going on :

bool Graph::isCyclicUtil(int v, bool visited[], int parent) 
{ 
    // Mark the current node as visited 
    visited[v] = true; 

    // Recur for all the vertices adjacent to this vertex 
    list<int>::iterator i; 
    for (i = adj[v].begin(); i != adj[v].end(); ++i) 
    { 
        // If an adjacent is not visited, then recur for that adjacent 
        if (!visited[*i]) 
        { 
           if (isCyclicUtil(*i, visited, v)) 
              return true; 
        } 

        // If an adjacent is visited and not parent of current vertex, 
        // then there is a cycle. 
        else if (*i != parent) 
           return true; 
    } 
    return false; 
} 

The above code explains itself but I will try to explain one condition i.e *i != parent Here if suppose graph is

1--2

Then when we are at 1 and goes to 2, the parent for 2 becomes 1 and when we go back to 1 as 1 is in adj matrix of 2 then since next vertex 1 is also the parent of 2 Therefore cycle will not be detected for the immediate parent in this DFS approach. Hence Code works fine

A and B be two rectangle. C be their covering rectangle.

four points of A be (xAleft,yAtop),(xAleft,yAbottom),(xAright,yAtop),(xAright,yAbottom)
four points of A be (xBleft,yBtop),(xBleft,yBbottom),(xBright,yBtop),(xBright,yBbottom)

A.width = abs(xAleft-xAright);
A.height = abs(yAleft-yAright);
B.width = abs(xBleft-xBright);
B.height = abs(yBleft-yBright);

C.width = max(xAleft,xAright,xBleft,xBright)-min(xAleft,xAright,xBleft,xBright);
C.height = max(yAtop,yAbottom,yBtop,yBbottom)-min(yAtop,yAbottom,yBtop,yBbottom);

A and B does not overlap if
(C.width >= A.width + B.width )
OR
(C.height >= A.height + B.height) 

It takes care all possible cases.

you need to fill only starting 2-3 numbers (or text for that matter) and then drag the range down using fill handle. MS Excel will identify the series by itself and will fill the range till where you drag down the range. The below image shows the ‘Fill Handle’.

We use a sonicwall vpn. It launches a java applet that launches mstc with all the credentials setup. You really can't do this without a java applet or activex plugin.

Microsoft uses this technique itself on their small business server for getting inside the network. I wouldn't say it is a terrible idea, as long as platform independence isn't important.

Open the command prompt in Windows or terminal in Linux and Mac.Type

node -v

If node is install it will show its version.For eg.,

Else download it from nodejs.org

I'm adding an answer to address an issue noted in some comments above: that inline ansi color codes can misbehave when inside a FOR loop (actually, within any parenthesized block of code). The .bat code below demonstrates (1) the use of inline color codes, (2) the color failure that can occur when inline color codes are used in a FOR loop or within a parenthesized block of code, and (3) a solution to the problem. When the .bat code executes, tests 2 and 3 demonstrate the colorcode failure, and test 4 shows no failure because it implements the solution.

[EDIT 2020-04-07: I found another solution that's presumably more efficient than calling a subroutine. Enclose the FINDSTR phrase in parentheses, as in the following line:

   echo success | (findstr /R success)

ENDEDIT]

Note: In my (limited) experience, the color code problem manifests only after input is piped to FINDSTR inside the block of code. That's how the following .bat reproduces the problem. It's possible the color code problem is more general than after piping to FINDSTR. If someone can explain the nature of the problem, and if there's a better way to solve it, I'd appreciate it.

@goto :main
:resetANSI
EXIT /B
rem  The resetANSI subroutine is used to fix the colorcode
rem  bug, even though it appears to do nothing.

:main
@echo off
setlocal EnableDelayedExpansion

rem  Define some useful colorcode vars:
for /F "delims=#" %%E in ('"prompt #$E# & for %%E in (1) do rem"') do set "ESCchar=%%E"
set "green=%ESCchar%[92m"
set "yellow=%ESCchar%[93m"
set "magenta=%ESCchar%[95m"
set "cyan=%ESCchar%[96m"
set "white=%ESCchar%[97m"
set "black=%ESCchar%[30m"

echo %white%Test 1 is NOT in a FOR loop nor within parentheses, and color works right.
   echo %yellow%[Test 1] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is magenta and FINDSTR found and displayed 'success'.%yellow%
   echo %green%This is green.
echo %cyan%Test 1 completed.

echo %white%Test 2 is within parentheses, and color stops working after the pipe to FINDSTR.
(  echo %yellow%[Test 2] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is supposed to be magenta and FINDSTR found and displayed 'success'.
   echo %green%This is supposed to be green.
)
echo %cyan%Test 2 completed.

echo %white%Test 3 is within a FOR loop, and color stops working after the pipe to FINDSTR.
for /L %%G in (3,1,3) do (
   echo %yellow%[Test %%G] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   echo %magenta%This is supposed to be magenta and FINDSTR found and displayed 'success'.
   echo %green%This is supposed to be green.
)
echo %cyan%Test 3 completed.

echo %white%Test 4 is in a FOR loop but color works right because subroutine :resetANSI is 
echo called after the pipe to FINDSTR, before the next color code is used.
for /L %%G in (4,1,4) do (
   echo %yellow%[Test %%G] %green%This is Green, %magenta%this is Magenta, and %yellow%this is Yellow.
   echo %Next, the string 'success' will be piped to FINDSTR...
   echo success | findstr /R success
   call :resetANSI
   echo %magenta%This is magenta and FINDSTR found and displayed 'success'.
   echo %green%This is green.
)
echo %cyan%Test 4 completed.%white%

EXIT /B

If by "empty", you mean with no HTML content,

if($('#element').html() == "") {
  //call function
}

I was able to make this work with the

transform: scale(1.03);

Property applied on the image. For some reason, on Chrome, the other solutions provided wouldn't work if there was any relatively positioned parent element.

Check http://jsfiddle.net/ud5ya7jt/

This way the image will be slightly zoomed in by 3% and the edges will be cropped which shouldn't be a problem on a blurred image anyway. It worked well in my case because I was using a high res image as a background. Good luck!

Bit late however I use

curl -4 icanhazip.com 

returns the server Primary IP address.

As shown here, the second argument to substr is the length, not the ending position:

string substr ( size_t pos = 0, size_t n = npos ) const;

Generate substring

Returns a string object with its contents initialized to a substring of the current object. This substring is the character sequence that starts at character position pos and has a length of n characters.

Your line b = a.substr(i,i+1); will generate, for values of i:

substr(0,1) = 1
substr(1,2) = 23
substr(2,3) = 345
substr(3,4) = 45  (since your string stops there).

What you need is b = a.substr(i,2);

You should also be aware that your output will look funny for a number like 12045. You'll get 12 20 4 45 due to the fact that you're using atoi() on the string section and outputting that integer. You might want to try just outputing the string itself which will be two characters long:

b = a.substr(i,2);
cout << b << " ";

In fact, the entire thing could be more simply written as:

#include <iostream>
#include <string>
using namespace std;
int main(void) {
    string a;
    cin >> a;
    for (int i = 0; i < a.size() - 1; i++)
        cout << a.substr(i,2) << " ";
    cout << endl;
    return 0;
}

I use the following for my HTML templates:

$(".main").empty();

var _template = '<p id="myelement">Your HTML Code</p>';
var template = $.parseHTML(_template);
var final = $(template).find("#myelement");

$(".main").append(final.html());

Note: Assuming if you are using jQuery

Visual Studio with C# key bindings

To answer the specific question, in C# you are likely to be using the C# keyboard mapping scheme, which will use these hotkeys by default:

Ctrl+E, Ctrl+D to format the entire document.

Ctrl+E, Ctrl+F to format the selection.

You can change these in menu Tools ? Options ? Environment ? Keyboard (either by selecting a different "keyboard mapping scheme", or binding individual keys to the commands "Edit.FormatDocument" and "Edit.FormatSelection").

If you have not chosen to use the C# keyboard mapping scheme, then you may find the key shortcuts are different. For example, if you are not using the C# bindings, the keys are likely to be:

Ctrl + K + D (Entire document)

Ctrl + K + F (Selection only)

To find out which key bindings apply in your copy of Visual Studio, look in menu Edit ? Advanced menu - the keys are displayed to the right of the menu items, so it's easy to discover what they are on your system.

_{(Please do not edit this answer to change the key bindings above to what your system has!)}

The w and h variables in img.onload function are not in the same scope with those in the getMeta() function. One way to do it, is as follows:

Fiddle: http://jsfiddle.net/ppanagi/28UES/2/

function getMeta(varA, varB) {
    if (typeof varB !== 'undefined') {
       alert(varA + ' width ' + varB + ' height');
    } else {
       var img = new Image();
       img.src = varA;
       img.onload = getMeta(this.width, this.height);
    }
}


getMeta("http://snook.ca/files/mootools_83_snookca.png");

My first suggestion is to use Designer to create your GUIs. Typing them out yourself sucks, takes more time, and you will definitely make more mistakes than Designer.

Here are some PyQt tutorials to help get you on the right track. The first one in the list is where you should start.

A good guide for figuring out what methods are available for specific classes is the PyQt4 Class Reference. In this case you would look up QLineEdit and see the there is a text method.

To answer your specific question:

To make your GUI elements available to the rest of the object, preface them with self.

import sys
from PyQt4.QtCore import SIGNAL
from PyQt4.QtGui import QDialog, QApplication, QPushButton, QLineEdit, QFormLayout

class Form(QDialog):
    def __init__(self, parent=None):
        super(Form, self).__init__(parent)

        self.le = QLineEdit()
        self.le.setObjectName("host")
        self.le.setText("Host")

        self.pb = QPushButton()
        self.pb.setObjectName("connect")
        self.pb.setText("Connect") 

        layout = QFormLayout()
        layout.addWidget(self.le)
        layout.addWidget(self.pb)

        self.setLayout(layout)
        self.connect(self.pb, SIGNAL("clicked()"),self.button_click)
        self.setWindowTitle("Learning")

    def button_click(self):
        # shost is a QString object
        shost = self.le.text()
        print shost


app = QApplication(sys.argv)
form = Form()
form.show()
app.exec_()

A plugin to blink some text sounds a bit like overkill to me...

Try this...

$('.blink').each(function() {
    var elem = $(this);
    setInterval(function() {
        if (elem.css('visibility') == 'hidden') {
            elem.css('visibility', 'visible');
        } else {
            elem.css('visibility', 'hidden');
        }    
    }, 500);
});

I had the same issue. Setting up the Android SDK is also a correct answer. But this is very simple -

1. Import an android project to a new Android studio window.
2. Close your current Flutter project Android studio window.
3. Import that Flutter project to new Android Studio window.

Here is a simple example for others visiting this old post, but is confused by the example in the question and the other answer:

Delivery -> Package (One -> Many)

CREATE TABLE Delivery(
    Id INT IDENTITY PRIMARY KEY,
    NoteNumber NVARCHAR(255) NOT NULL
)

CREATE TABLE Package(
    Id INT IDENTITY PRIMARY KEY,
    Status INT NOT NULL DEFAULT 0,
    Delivery_Id INT NOT NULL,
    CONSTRAINT FK_Package_Delivery_Id FOREIGN KEY (Delivery_Id) REFERENCES Delivery (Id) ON DELETE CASCADE
)

The entry with the foreign key Delivery_Id (Package) is deleted with the referenced entity in the FK relationship (Delivery).

So when a Delivery is deleted the Packages referencing it will also be deleted. If a Package is deleted nothing happens to any deliveries.

No need for the option, just make the preferred width of the last column the maximum and it will take all the extra space.

table.getColumnModel().getColumn(0).setPreferredWidth(27);
table.getColumnModel().getColumn(1).setPreferredWidth(120);
table.getColumnModel().getColumn(2).setPreferredWidth(100);
table.getColumnModel().getColumn(3).setPreferredWidth(90);
table.getColumnModel().getColumn(4).setPreferredWidth(90);
table.getColumnModel().getColumn(6).setPreferredWidth(120);
table.getColumnModel().getColumn(7).setPreferredWidth(100);
table.getColumnModel().getColumn(8).setPreferredWidth(95);
table.getColumnModel().getColumn(9).setPreferredWidth(40);
table.getColumnModel().getColumn(10).setPreferredWidth(Integer.MAX_INT);

To get only own methods, and exclude inherited ones:

From within the instance:

self.methods - self.class.superclass.instance_methods

From outside:

TestClass.instance_methods - TestClass.superclass.instance_methods

Add it to the class:

class TestClass
  class << self
    def own_methods
      self.instance_methods - self.superclass.instance_methods
    end
  end
end

TestClass.own_methods
=> [:method1, :method2, :method3]

(with ruby 2.6.x)

You can let PHP do a POST, but then your php will get the return, with all sorts of complications. I think the simplest would be to actually let the user do the POST.

So, kind-of what you suggested, you'll get indeed this part:

Customer fill detail in Page A, then in Page B we create another page show all the customer detail there, click a CONFIRM button then POST to Page C.

But you can actually do a javascript submit on page B, so there is no need for a click. Make it a "redirecting" page with a loading animation, and you're set.

In order to solve your problem you should do this:

this._camera = Camera.open();     
this._camera.startPreview();
this._camera.autoFocus(new AutoFocusCallback() {
public void onAutoFocus(boolean success, Camera camera) {
}
});

Parameters params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_ON);
this._camera.setParameters(params);

params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
this._camera.setParameters(params);

don't worry about FLASH_MODE_OFF because this will keep the light on, strange but it's true

to turn off the led just release the camera

Actually you don't get the meaning of Boolean method.It always return true if the variable is not null or empty.

var variable = some value; Boolean(variable);

If my variable have some value then it will return true else return false You can't use Boolean as you think.

I did the redistributable repair thing, but for me it worked after I installed Office365.

(for me it also was the last failing package on the list).

You're remarkably close.

Here's the code you wrote in the question:

questionText.replace(/[0-9]/g, '');

The code you've written does indeed look at the questionText variable, and produce output which is the original string, but with the digits replaced with empty string.

However, it doesn't assign it automatically back to the original variable. You need to specify what to assign it to:

questionText = questionText.replace(/[0-9]/g, '');

First you have to click on the report, Then View -> Report Data

The problem is that you use a localizing formatter that generates locale-specific decimal point, which is "," in your case. But Double.parseDouble() expects non-localized double literal. You could solve your problem by using a locale-specific parsing method or by changing locale of your formatter to something that uses "." as the decimal point. Or even better, avoid unnecessary formatting by using something like this:

double rounded = (double) Math.round(value * 100.0) / 100.0;

And here is a simple Send-MailMessage example with username/password for anyone looking for just that

$secpasswd = ConvertTo-SecureString "PlainTextPassword" -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential ("username", $secpasswd)
Send-MailMessage -SmtpServer mysmptp -Credential $cred -UseSsl -From '[email protected]' -To '[email protected]' -Subject 'TEST'

POSIX is a family of standards, specified by the IEEE, to clarify and make uniform the application programming interfaces (and ancillary issues, such as commandline shell utilities) provided by Unix-y operating systems. When you write your programs to rely on POSIX standards, you can be pretty sure to be able to port them easily among a large family of Unix derivatives (including Linux, but not limited to it!); if and when you use some Linux API that's not standardized as part of Posix, you will have a harder time if and when you want to port that program or library to other Unix-y systems (e.g., MacOSX) in the future.

I'm not sure of your exact requirement but one possible solution to improve 'readability' is to store it as an array.

{
  "testCases" :
  {
    "case.1" :
    {
      "scenario" : "this the case 1.",
      "result" : ["this is a very long line which is not easily readble.",
                  "so i would like to write it in multiple lines.",
                  "but, i do NOT require any new lines in the output."]
    }
  }
}

}

The join in back again whenever required with

result.join(" ")

try this one, it is working fine for me.

"^([a-zA-Z])[a-zA-Z0-9-_]*$"

Dropdown list wont allows multiple item select in dropdown.

If you need , you can use listbox control..

ASP.NET List Box

You can also move mounted out of the Vue instance and make it a function in the top-level scope. This is also a useful trick for server side rendering in Vue.

function init() {
  // Use `this` normally
}

new Vue({
  methods:{
    init
  },
  mounted(){
    init.call(this)
  }
})

You have to install Python and add it to PATH on Windows. After that you can try:

python `C:/pathToFolder/prog.py`

or go to the files directory and execute:

python prog.py

This powershell example looks for all instances of the string "\foo\" in a folder and its subfolders, replaces "\foo\" with "\bar\" AND DOES NOT REWRITE files that don't contain the string "\foo\" This way you don't destroy the file last update datetime stamps where the string was not found:

Get-ChildItem  -Path C:\YOUR_ROOT_PATH\*.* -recurse 
 | ForEach {If (Get-Content $_.FullName | Select-String -Pattern '\\foo\\') 
           {(Get-Content $_ | ForEach {$_ -replace '\\foo\\', '\bar\'}) | Set-Content $_ }
           }

For your particular example, I would just do this, since you obviously don't care about actually having the browser get the redirect anyway (by virtue of accepting the answer you have already accepted):

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index() {
   // obviously these values might come from somewhere non-trivial
   return Index(2, "text");
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(int someValue, string anotherValue) {
   // would probably do something non-trivial here with the param values
   return View();
}

That works easily and there is no funny business really going on - this allows you to maintain the fact that the second one really only accepts HTTP POST requests (except in this instance, which is under your control anyway) and you don't have to use TempData either, which is what the link you posted in your answer is suggesting.

I would love to know what is "wrong" with this, if there is anything. Obviously, if you want to really have sent to the browser a redirect, this isn't going to work, but then you should ask why you would be trying to convert that regardless, since it seems odd to me.

Hope that helps.

Just incase this helps anyone else also, I was signed into the mac app, command line working fine, but because I then turned on 2FA, my commands were returning the error. I had to sign out of the app, then I could use my Personal access token in my commands as per ele's answer here.

Hopefully that helps someone!

If you use MyISAM tables, the fastest way is querying directly the stats:

select table_name, table_rows 
     from information_schema.tables 
where 
     table_schema='databasename' and 
     table_name in ('user_table','cat_table','course_table')

If you have InnoDB you have to query with count() as the reported value in information_schema.tables is wrong.

After trying and reading carefully, I solved it myself. Solution is to add the following line in build.gradle.

flavorDimensions "versionCode"

android { 
       compileSdkVersion 24
       .....
       flavorDimensions "versionCode"
} 

Along with JFileChooser is possible use this:

UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");

for have a Look and Feel like Windows.

for others settings, view here: https://docs.oracle.com/javase/tutorial/uiswing/lookandfeel/plaf.html#available

That's because you created a Web Site instead of a Web Application. The cs/vb files can only be seen in a Web Application, but in a website you can't have a separate cs/vb file.

Edit: In the website you can add a cs file behavior like..

<%@ Application CodeFile="Global.asax.cs" Inherits="ApplicationName.MyApplication" Language="C#" %>

~/Global.asax.cs:

namespace ApplicationName
{
    public partial class MyApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
        }
    }
}

To a kill a specific port in Linux use below command

sudo fuser -k Port_Number/tcp

replace Port_Number with your occupied port.

If you don't want to or can't use Android Studio, you can use the create-android-keystore NPM tool:

$ create-android-keystore quick

Which results in a newly generated keystore in the current directory.

More info: https://www.npmjs.com/package/create-android-keystore

for this simply follow below query

select a.Id,a.type,b.Name,b.City from DatabaseName.dbo.TableName a left join DatabaseName.dbo.TableName b on a.Id=b.Id

Where I wrote databasename, you have to define the name of the database. If you are in same database so you don't need to define the database name but if you are in other database you have to mention database name as path or it will show you error. Hope I made your work easy

Tick 'Full Index Enabled' and then 'Rebuild Index' of the central repository in 'Global Repositories' under Window > Show View > Other > Maven > Maven Repositories, and it should work.

The rebuilding may take a long time depending on the speed of your internet connection, but eventually it works.

have at look at the static methods DateTime.Parse() and DateTime.TryParse(). They will allow you to pass in your date string and a format string, and get a DateTime object in return.

This is a paragraph option. Go to Window>Paragraph then a small window will pop up. You will have two buttons on the bottom. One with a arrow on the left of P and one on the right. Select the right one.

Connect to a different repository (I tried with a TFS repository), then go to Manage Connections, right click the Git repository and you might be able to remove it.

But you still have to manually remove the .git folder and files from your project path before opening the solution again.

If you are using an IDE like eclipse, you can use this easy way.

Right click on the project -> Team - Show history

In that right click on the revision id for your commit and select 'Set commit properties'.

You can modify the message as you want from here.

This is an old question, but is still regularly viewed/needed. I want to post to caution readers like me that whitespace as mentioned in the OP's question is not the same as Regex's definition, to include newlines, tabs, and space characters -- Git asks you to be explicit. See some options here: https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration

As stated, git diff -b or git diff --ignore-space-change will ignore spaces at line ends. If you desire that setting to be your default behavior, the following line adds that intent to your .gitconfig file, so it will always ignore the space at line ends:

git config --global core.whitespace trailing-space

In my case, I found this question because I was interested in ignoring "carriage return whitespace differences", so I needed this:

git diff --ignore-cr-at-eol or git config --global core.whitespace cr-at-eol from here.

You can also make it the default only for that repo by omitting the --global parameter, and checking in the settings file for that repo. For the CR problem I faced, it goes away after check-in if warncrlf or autocrlf = true in the [core] section of the .gitconfig file.

Solution 1:

1. php -v

Output: PHP 7.3.11-1+ubuntu16.04.1+deb.sury.org+1 (cli)

2. sudo apt-get install php7.3-mysql

Solution 2:

Check your DB credentials like DB Name, DB User, DB Password

If this ()Unsupported method: BaseConfig.getApplicationIdSuffix Android Project is old and you have updated Android Studio, what I did was simply CLOSE PROJECT and ran it again. It solved the issue for me. Did not add any dependencies or whatever as described by other answers.

I fixed this problem by changing the first line in Application.mk from

APP_STL := gnustl_static

to

APP_STL := c++_static

On Linux I use:

lsof -P -T -p Application_PID

This works better than ldd when the executable uses a non default loader

This might work: You can disable selecting with css3 for text, image and basically everything.

.unselectable {
   -moz-user-select: -moz-none;
   -khtml-user-select: none;
   -webkit-user-select: none;

   /*
     Introduced in IE 10.
     See http://ie.microsoft.com/testdrive/HTML5/msUserSelect/
   */
   -ms-user-select: none;
   user-select: none;
}

Of course only for the newer browsers. For more details check:

You can add element to arrayList using add() method in Kotlin. For example,

arrayList.add(10)

Above code will add element 10 to arrayList.

However, if you are using Array or List, then you can not add element. This is because Array and List are Immutable. If you want to add element, you will have to use MutableList.

Several workarounds:

1. Using System.arraycopy() method: You can achieve same target by creating new array and copying all the data from existing array into new one along with new values. This way you will have new array with all desired values(Existing and New values)
2. Using MutableList:: Convert array into mutableList using toMutableList() method. Then, add element into it.
3. Using Array.copyof(): Somewhat similar as System.arraycopy() method.

Sometimes if you use JavaScript the DocumentComplete event don't return the right answer; I use the event ProgressChanged instead:

Private Sub WebBrowser1_ProgressChanged(sender As Object, e As WebBrowserProgressChangedEventArgs) Handles WebBrowser1.ProgressChanged

        Console.WriteLine("Current Progress: " + e.CurrentProgress.ToString)

        If e.CurrentProgress = e.MaximumProgress Then

            ' The maximum progress is reached
            load_started = True

        End If

        ' The page is confirmed downloaded after the progress returns to 0
        If e.CurrentProgress = 0 Then

            If load_started Then

                ' The page is ready to print or download...
                WebBrowser1.Print()
                load_started = False

            End If

        End If

End Sub

1. Create a hidden button with id="hiddenBtn" and type="submit" that do the submit
2. Change current button to type="button"

3. set onclick of the current button call a function look like below:

   function foo() { // do something before submit ... // trigger click event of the hidden button $('#hinddenBtn').trigger("click"); }

I came across this when I started using three.js as well. It's actually a javascript issue. You currently have:

renderer.setClearColorHex( 0x000000, 1 );

in your threejs init function. Change it to:

renderer.setClearColorHex( 0xffffff, 1 );

Update: Thanks to HdN8 for the updated solution:

renderer.setClearColor( 0xffffff, 0);

Update #2: As pointed out by WestLangley in another, similar question - you must now use the below code when creating a new WebGLRenderer instance in conjunction with the setClearColor() function:

var renderer = new THREE.WebGLRenderer({ alpha: true });

Update #3: Mr.doob points out that since r78 you can alternatively use the code below to set your scene's background colour:

var scene = new THREE.Scene(); // initialising the scene
scene.background = new THREE.Color( 0xff0000 );

I know this is a little old, but I recently came across this while looking for a similar solution. Relying on hover events isn't good for responsive design, and especially terrible on mobile/touch screens. I ended up making a small edit to the dropdown.js file the allows you to click the menu item to open the menu and if you click the menu item again it will follow it.

The nice thing about this is it doesn't rely on hover at all and so it still works really nicely on a touch screen.

I've posted it here: https://github.com/mrhanlon/twbs-dropdown-doubletap/blob/master/js/dropdown-doubletap.js

Hope that helps!

Use the CheckBoxList's GetItemChecked or GetItemCheckState method to find out whether an item is checked or not by its index.

If you want to clean up Solr index -

you can fire http url -

http://host:port/solr/[core name]/update?stream.body=<delete><query>*:*</query></delete>&commit=true

(replace [core name] with the name of the core you want to delete from). Or use this if posting data xml data:

<delete><query>*:*</query></delete>

Be sure you use commit=true to commit the changes

Don't have much idea with clearing hbase data though.

The easiest solution I found is to just rename the php folder version as such:

1. Shut down the servers
2. Rename the folder containing the php version that you don't need in /Applications/MAMP/bin/php. php7.3.9 --> _php7.3.9

That way only two of them will be read by MAMP. Done!

That's because the result of adding two Int16 is an Int32. Check the "conversions" paragraph here: http://msdn.microsoft.com/en-us/library/ybs77ex4%28v=vs.71%29.aspx

Try this:

jsonResponse = json.loads(response.decode('utf-8'))

If you are allowed to go further then javascript/html facilities - I would use the apache web server to represent your directory listing via http.

If this solution is appropriate. these are the steps:

1. download apache hhtp server from one of the mirrors http://httpd.apache.org/download.cgi

2. unzip/install (if msi) it to the directory e.g C:\opt\Apache (the instruction is for windows)

3. map the network forlder as a local drive on windows (\server\folder to let's say drive H:)

4. open conf/httpd.conf file

5. make sure the next line is present and not commented

   LoadModule autoindex_module modules/mod_autoindex.so

6. Add directory configuration

<Directory "H:/path">

Options +Indexes

AllowOverride None

Order allow,deny

Allow from all

</Directory> 7. Start the web server and make sure the directory listingof the remote folder is available by http. hit localhost/path 8. use a frame inside your web page to access the listing

What is missed: 1. you mignt need more fancy configuration for the host name, refer to Apache Web Server docs. Register the host name in DNS server

1. the mapping to the network drive might not work, i did not check. As a posible resolution - host your web server on the same machine as smb server.

I would do it with awk, e.g.

awk '/[0-9]+/ { a = a $0 ";" } END { print a }' file.txt

(a disadvantage is that a is "accumulated" in memory).

EDIT

Forgot about printf! So also

awk '/[0-9]+/ { printf "%s;", $0 }' file.txt

or likely better, what it was already given in the other ans using awk.

"Not Possible". You can do this using this query. Initialize here

declare @sql nvarchar(4000)=''

Set Value & exec command of your sp with parameters

SET @sql += ' Exec spName @param'
EXECUTE sp_executesql @sql,  N'@param type', @param = @param

You can pass a string with your list and use a prepared statements to run a query, e.g. -

DELIMITER $$

CREATE PROCEDURE GetFruits(IN fruitArray VARCHAR(255))
BEGIN

  SET @sql = CONCAT('SELECT * FROM Fruits WHERE Name IN (', fruitArray, ')');
  PREPARE stmt FROM @sql;
  EXECUTE stmt;
  DEALLOCATE PREPARE stmt;

END
$$

DELIMITER ;

How to use:

SET @fruitArray = '\'apple\',\'banana\'';
CALL GetFruits(@fruitArray);

 <c:forEach items="${sessionScope.empL}" var="emp">
            <tr>
                <td>Employee ID: <c:out value="${emp.eid}"/></td>
                <td>Employee Pass: <c:out value="${emp.ename}"/></td>  
            </tr>
        </c:forEach>

There are 2 options to find matching text; string.match or string.find.

Both of these perform a regex search on the string to find matches.

string.find()

string.find(subject string, pattern string, optional start position, optional plain flag)

Returns the startIndex & endIndex of the substring found.

The plain flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger) being interpreted as a regex capture group matching for tiger, it instead looks for (tiger) within a string.

Going the other way, if you want to regex match but still want literal special characters (such as .()[]+- etc.), you can escape them with a percentage; %(tiger%).

You will likely use this in combination with string.sub

Example

str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

string.match()

string.match(s, pattern, optional index)

Returns the capture groups found.

Example

str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

SELECT *
FROM table
WHERE myDtate BETWEEN now()
    , DATE_SUB(NOW()
    , INTERVAL 1 MONTH)

As of API 26, getDeviceId() is deprecated. If you need to get the IMEI of the device, use the following:

 String deviceId = "";
    if (Build.VERSION.SDK_INT >= 26) {
        deviceId = getSystemService(TelephonyManager.class).getImei();
    }else{
        deviceId = getSystemService(TelephonyManager.class).getDeviceId();
    }

Sergio Carneiro's and Jon's implementation requires you to define an initializer function for all but one class. Here is a modified version of the aggregation function, which makes use of default parameters in the constructors instead. Included are also some comments by me.

var aggregation = (baseClass, ...mixins) => {
    class base extends baseClass {
        constructor (...args) {
            super(...args);
            mixins.forEach((mixin) => {
                copyProps(this,(new mixin));
            });
        }
    }
    let copyProps = (target, source) => {  // this function copies all properties and symbols, filtering out some special ones
        Object.getOwnPropertyNames(source)
              .concat(Object.getOwnPropertySymbols(source))
              .forEach((prop) => {
                 if (!prop.match(/^(?:constructor|prototype|arguments|caller|name|bind|call|apply|toString|length)$/))
                    Object.defineProperty(target, prop, Object.getOwnPropertyDescriptor(source, prop));
               })
    }
    mixins.forEach((mixin) => { // outside contructor() to allow aggregation(A,B,C).staticFunction() to be called etc.
        copyProps(base.prototype, mixin.prototype);
        copyProps(base, mixin);
    });
    return base;
}

Here is a little demo:

class Person{
   constructor(n){
      this.name=n;
   }
}
class Male{
   constructor(s='male'){
      this.sex=s;
   }
}
class Child{
   constructor(a=12){
      this.age=a;
   }
   tellAge(){console.log(this.name+' is '+this.age+' years old.');}
}
class Boy extends aggregation(Person,Male,Child){}
var m = new Boy('Mike');
m.tellAge(); // Mike is 12 years old.

This aggregation function will prefer properties and methods of a class that appear later in the class list.

You can try this if you want to override

var newArray= [444,555,666];
var oldArray =[11,22,33];
oldArray.forEach((name, index) => oldArray [index] = newArray[index]);
console.log(newArray);

This can happen if any part of your highlighted method or property is attempting to access a property or method with the incorrect type.

Here is a troubleshooting checklist:

• Make sure the type of arguments match in the call site and implementation.
• Make sure the argument names match in the call site and implementation.
• Make sure the method name matches in the call site and implementation.
• Make sure the returned value of a property or method matches in the usage and implementation (ie: enumerated())
• Make sure you don't have a duplicated method with potentially ambiguous types such as with protocols or generics.
• Make sure the compiler can infer the correct type when using type inference.

A Strategy

• Try breaking apart your method into a greater number of simpler method/implementations.

For example, lets say you are running compactMap on an array of custom Types. In the closure you are passing to the compactMap method, you initialize and return another custom struct. When you get this error, it is difficult to tell which part of your code is offending.

• For debugging purposes, you can use a for loop instead of compactMap.
• instead of passing the arguments, directly, you can assign them to constants in the for loop.

By this point, you may come to a realization, such as, instead of the property you thought you wanted to assign actually had a property on it that had the actual value you wanted to pass.

My 2¢! Really, part of the reason I'm throwing this up here, despite the long list of answers, is to provide a little more all in one type solution and get some feed back in the future on how to expand it to include more real types.

With the following solution, as aforementioned, I combined a couple of solutions found here, as well as incorporate a fix for returning a value of jQuery on jQuery defined object if available. I also append the method to the native Object prototype. I know that is often taboo, as it could interfere with other such extensions, but I leave that to user beware. If you don't like this way of doing it, simply copy the base function anywhere you like and replace all variables of this with an argument parameter to pass in (such as arguments[0]).

;(function() {  //  Object.realType
    function realType(toLower) {
        var r = typeof this;
        try {
            if (window.hasOwnProperty('jQuery') && this.constructor && this.constructor == jQuery) r = 'jQuery';
            else r = this.constructor && this.constructor.name ? this.constructor.name : Object.prototype.toString.call(this).slice(8, -1);
        }
        catch(e) { if (this['toString']) r = this.toString().slice(8, -1); }
        return !toLower ? r : r.toLowerCase();
    }
    Object['defineProperty'] && !Object.prototype.hasOwnProperty('realType')
        ? Object.defineProperty(Object.prototype, 'realType', { value: realType }) : Object.prototype['realType'] = realType;
})();

Then simply use with ease, like so:

obj.realType()  //  would return 'Object'
obj.realType(true)  //  would return 'object'

Note: There is 1 argument passable. If is bool of true, then the return will always be in lowercase.

More Examples:

true.realType();                            //  "Boolean"
var a = 4; a.realType();                    //  "Number"
$('div:first').realType();                   // "jQuery"
document.createElement('div').realType()    //  "HTMLDivElement"

If you have anything to add that maybe helpful, such as defining when an object was created with another library (Moo, Proto, Yui, Dojo, etc...) please feel free to comment or edit this and keep it going to be more accurate and precise. OR roll on over to the GitHub I made for it and let me know. You'll also find a quick link to a cdn min file there.

Try this:

 $(document).ready(function() {
// When the document is ready
// Do something  
});

I guess in the context of neural network terminology:

• Epoch: When your network ends up going over the entire training set (i.e., once for each training instance), it completes one epoch.

In order to define iteration (a.k.a steps), you first need to know about batch size:

• Batch size: You probably wouldn't like to process the entire training instances all at one forward pass as it is inefficient and needs a huge deal of memory. So what is commonly done is splitting up training instances into subsets (i.e., batches), performing one pass over the selected subset (i.e., batch), and then optimizing the network through backpropagation. The number of training instances within a subset (i.e., batch) is called batch_size.

• Iteration: (a.k.a training steps) You know that your network has to go over all training instances in one pass in order to complete one epoch. But wait! when you are splitting up your training instances into batches, that means you can only process one batch (a subset of training instances) in one forward pass, so what about the other batches? This is where the term Iteration comes into play:

• Definition: The number of forward passes (The number of batches that you have created) that your network has to do in order to complete one epoch (i.e., going over all training instances) is called Iteration.

For example, when you have 10000 training instances and you want to do batching with size of 10; you have to do 10000/10 = 1000 iterations to complete 1 epoch.

Hope this could answer your question!

Give this a try:

CGRect frame = self.textView.frame;
frame.size.height = self.textView.contentSize.height;
self.textView.frame = frame;

Edit- Here's the Swift:

var frame = self.textView.frame
frame.size.height = self.textView.contentSize.height
self.textView.frame = frame

I tried a lot of workarrounds and non of them worked for me. The exception was "The required anti-forgery form field "__RequestVerificationToken" .

    });

Anaconda does not use the PYTHONPATH. One should however note that if the PYTHONPATH is set it could be used to load a library that is not in the anaconda environment. That is why before activating an environment it might be good to do a

unset PYTHONPATH

For instance this PYTHONPATH points to an incorrect pandas lib:

export PYTHONPATH=/home/john/share/usr/anaconda/lib/python
source activate anaconda-2.7
python
>>>> import pandas as pd
/home/john/share/usr/lib/python/pandas-0.12.0-py2.7-linux-x86_64.egg/pandas/hashtable.so: undefined symbol: PyUnicodeUCS2_DecodeUTF8
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/john/share/usr/lib/python/pandas-0.12.0-py2.7-linux-x86_64.egg/pandas/__init__.py", line 6, in <module>
    from . import hashtable, tslib, lib
ImportError: /home/john/share/usr/lib/python/pandas-0.12.0-py2.7-linux-x86_64.egg/pandas/hashtable.so: undefined symbol: PyUnicodeUCS2_DecodeUTF8

unsetting the PYTHONPATH prevents the wrong pandas lib from being loaded:

unset PYTHONPATH
source activate anaconda-2.7
python
>>>> import pandas as pd
>>>>

simple do id:("12345") OR id:("7890") .... and so on

/* (opener) */ (closer)

for example,

<html>
 /*<p>Commented P Tag </p>*/
<html>

The variable item is a string. An index looks like this:

>>> mystring = 'helloworld'
>>> print mystring[0]
'h'

The above example uses the 0 index of the string to refer to the first character.

Strings can't have string indices (like dictionaries can). So this won't work:

>>> mystring = 'helloworld'
>>> print mystring['stringindex']
TypeError: string indices must be integers

In simple words.

In Python you should add self argument as the first argument to all defined methods in classes:

class MyClass:
  def method(self, arg):
    print(arg)

Then you can use your method according to your intuition:

>>> my_object = MyClass()
>>> my_object.method("foo")
foo

This should solve your problem :)

For a better understanding, you can also read the answers to this question: What is the purpose of self?

This answer comes from Steven Bethard on Google groups. I'm reposting it here to make it easier for people without a Google account to access.

You can override the default behavior of the error method:

import argparse
import sys

class MyParser(argparse.ArgumentParser):
    def error(self, message):
        sys.stderr.write('error: %s\n' % message)
        self.print_help()
        sys.exit(2)

parser = MyParser()
parser.add_argument('foo', nargs='+')
args = parser.parse_args()

Note that the above solution will print the help message whenever the error method is triggered. For example, test.py --blah will print the help message too if --blah isn't a valid option.

If you want to print the help message only if no arguments are supplied on the command line, then perhaps this is still the easiest way:

import argparse
import sys

parser=argparse.ArgumentParser()
parser.add_argument('foo', nargs='+')
if len(sys.argv)==1:
    parser.print_help(sys.stderr)
    sys.exit(1)
args=parser.parse_args()

Note that parser.print_help() prints to stdout by default. As init_js suggests, use parser.print_help(sys.stderr) to print to stderr.

Try setting the type of your parameter to [bool]:

param
(
    [int]$Turn = 0
    [bool]$Unity = $false
)

switch ($Unity)
{
    $true { "That was true."; break }
    default { "Whatever it was, it wasn't true."; break }
}

This example defaults $Unity to $false if no input is provided.

Usage

.\RunScript.ps1 -Turn 1 -Unity $false

Since you're using SQL 2008:

UPDATE
    table_Name

SET
    column_A  
     = CASE
        WHEN @flag = '1' THEN @new_value
        ELSE 0
    END + column_A,

    column_B  
     = CASE
        WHEN @flag = '0' THEN @new_value
        ELSE 0
    END + column_B 
WHERE
    ID = @ID

If you were using SQL 2012:

UPDATE
    table_Name
SET
    column_A  = column_A + IIF(@flag = '1', @new_value, 0),
    column_B  = column_B + IIF(@flag = '0', @new_value, 0)
WHERE
    ID = @ID

If you want to just auto focus any modal that was open you can put in you patterns or lib functions this snippet that will focus on the first input:

$('.modal').on('shown.bs.modal', function () {
  $(this).find('input:first').focus();
})

Here my solution

function getTime() {
var systemDate = new Date();
var hours = systemDate.getHours();
var minutes = systemDate.getMinutes();
var strampm;
if (hours >= 12) {
    strampm= "PM";
} else {
    strampm= "AM";
}
hours = hours % 12;
if (hours == 0) {
    hours = 12;
}
_hours = checkTimeAddZero(hours);
_minutes = checkTimeAddZero(minutes);
console.log(_hours + ":" + _minutes + " " + strampm);
}

function checkTimeAddZero(i) {
if (i < 10) {
    i = "0" + i
}
return i;
}

For debugging purposes, you can use the DLL file. You can run it using dotnet ConsoleApp2.dll. If you want to generate an EXE file, you have to generate a self-contained application.

To generate a self-contained application (EXE in Windows), you must specify the target runtime (which is specific to the operating system you target).

Pre-.NET Core 2.0 only: First, add the runtime identifier of the target runtimes in the .csproj file (list of supported RIDs):

<PropertyGroup>
    <RuntimeIdentifiers>win10-x64;ubuntu.16.10-x64</RuntimeIdentifiers>
</PropertyGroup>

The above step is no longer required starting with .NET Core 2.0.

Then, set the desired runtime when you publish your application:

dotnet publish -c Release -r win10-x64
dotnet publish -c Release -r ubuntu.16.10-x64

As of Git v2.23.0 (August 2019), git switch is preferred over git checkout when you’re simply switching branches/tags. I’m guessing they did this since git checkout had two functions: for switching branches and for restoring files. So in v2.23.0, they added two new commands, git switch, and git restore, to separate those concerns. I would predict at some point in the future, git checkout will be deprecated.

To switch to a normal branch, use git switch <branch-name>. To switch to a commit-like object, including single commits and tags, use git switch --detach <commitish>, where <commitish> is the tag name or commit number.

The --detach option forces you to recognize that you’re in a mode of “inspection and discardable experiments”. To create a new branch from the commitish you’re switching to, use git switch -c <new-branch> <start-point>.

Please follow the below steps.

begin
  for i in (select 'drop table '||table_name||' cascade constraints' tb from user_tables) 
  loop
     execute immediate i.tb;
  end loop;
  commit;
end;
purge RECYCLEBIN;

org.apache.commons.lang3.StringEscapeUtils from commons-lang3 is marked deprecated now. You can use org.apache.commons.text.StringEscapeUtils#unescapeJava(String) instead. It requires an additional Maven dependency:

        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-text</artifactId>
            <version>1.4</version>
        </dependency>

and seems to handle some more special cases, it e.g. unescapes:

• escaped backslashes, single and double quotes
• escaped octal and unicode values
• \\b, \\n, \\t, \\f, \\r

1. Method 1

The easy and effect way

open your .svg file with any text editor

<svg version="1.1" id="Capa_1" xmlns="http://www.w3.org/2000/svg" 
   xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
   viewBox="0 0 477.526 477.526" style="enable-background:new 0 0 477.526 477.526; 
   fill: rgb(109, 248, 248);" xml:space="preserve"> 
<svg />

give an style attribute and fill that with color

2. Another way

fill with color in your shape here i have rect shape fill="white

<svg width="800" height="600" xmlns="http://www.w3.org/2000/svg">
      <g>
          <title>background</title>
          <rect fill="#fff" id="canvas_background" height="602" width="802" y="-1" 
           x="-1"/>
           <g display="none" overflow="visible" y="0" x="0" height="100%" width="100%" 
           id="canvasGrid">
              <rect fill="url(#gridpattern)" stroke-width="0" y="0" x="0" height="100%" 
              width="100%"/>
           </g>

    }


}

    {
        case MessageComposeResultCancelled:  
            NSLog(@"Cancelled");    
            break; 
        case MessageComposeResultFailed:
            NSLog(@"Failed");
            break;   
        case MessageComposeResultSent:      
            break;

    }  
    [self dismissModalViewControllerAnimated:YES]; 
}

First check whether the file exists in SDCard. If the file doesnot exists in SDcard then you can set image using setImageResource() methodand passing default image from drawable folder

Sample Code

File imageFile = new File(absolutepathOfImage);//absolutepathOfImage is absolute path of image including its name
        if(!imageFile.exists()){//file doesnot exist in SDCard

        imageview.setImageResource(R.drawable.defaultImage);//set default image from drawable folder
        }

This error can occur if trying to grant privileges for a non-existing user.

It is not clear to me what MySQL considers a non-existing user. But I suspect MySQL considers a user to exist if it can be found by a name (column User) and a host (column Host) in the user table.

If trying to grant privileges to a user that can be found with his name (column User) but not by his name and host (columns User and Host), and not provide a password, then the error occurs.

For example, the following statement triggers the error:

grant all privileges on mydb.* to myuser@'xxx.xxx.xxx.xxx';

This is because, with no password being specified, MySQL cannot create a new user, and thus tries to find an existing user. But no user with the name myuser and the host xxx.xxx.xxx.xxx can be found in the user table.

Whereas providing a password, allows the statement to be executed successfully:

grant all privileges on mydb.* to myuser@'xxx.xxx.xxx.xxx' identified by 'mypassword';

Make sure to reuse the same password of that user you consider exists, if that new "MySQL user" is the same "application user".

Complete the operation by flushing the privileges:

flush privileges;

If you are in a directory where only root have access to write in system. Then you can directly use wget www.example.com/wget-test using a standard user account. So it will hit the url but because of having no write permission file won't be saved.. This method is working fine for me as i am using this method for a cronjob. Thanks.

The base dn is dc=example,dc=com.

I don't know about openca, but I will try this answer since you got very little traffic so far.

A base dn is the point from where a server will search for users. So I would try to simply use admin as a login name.

If openca behaves like most ldap aware applications, this is what is going to happen :

1. An ldap search for the user admin will be done by the server starting at the base dn (dc=example,dc=com).
2. When the user is found, the full dn (cn=admin,dc=example,dc=com) will be used to bind with the supplied password.
3. The ldap server will hash the password and compare with the stored hash value. If it matches, you're in.

Getting step 1 right is the hardest part, but mostly because we don't get to do it often. Things you have to look out for in your configuraiton file are :

• The dn your application will use to bind to the ldap server. This happens at application startup, before any user comes to authenticate. You will have to supply a full dn, maybe something like cn=admin,dc=example,dc=com.
• The authentication method. It is usually a "simple bind".
• The user search filter. Look at the attribute named objectClass for your admin user. It will be either inetOrgPerson or user. There will be others like top, you can ignore them. In your openca configuration, there should be a string like (objectClass=inetOrgPerson). Whatever it is, make sure it matches your admin user's object Class. You can specify two object class with this search filter (|(objectClass=inetOrgPerson)(objectClass=user)).

Download an LDAP Browser, such as Apache's Directory Studio. Connect using your application's credentials, so you will see what your application sees.

A dict's keys are stored in a hashtable so that is their 'natural order', i.e. psuedo-random. Any other ordering is a concept of the consumer of the dict.

sorted() always returns a list, not a dict. If you pass it a dict.items() (which produces a list of tuples), it will return a list of tuples [(k1,v1), (k2,v2), ...] which can be used in a loop in a way very much like a dict, but it is not in anyway a dict!

foo = {
    'a':    1,
    'b':    2,
    'c':    3,
    }

print foo
>>> {'a': 1, 'c': 3, 'b': 2}

print foo.items()
>>> [('a', 1), ('c', 3), ('b', 2)]

print sorted(foo.items())
>>> [('a', 1), ('b', 2), ('c', 3)]

The following feels like a dict in a loop, but it's not, it's a list of tuples being unpacked into k,v:

for k,v in sorted(foo.items()):
    print k, v

Roughly equivalent to:

for k in sorted(foo.keys()):
    print k, foo[k]

Not really. GUID is more Microsoft-centric whereas UUID is used more widely (e.g., as in the urn:uuid: URN scheme, and in CORBA).

Add #pragma comment(lib, "Your library name here") to your source.

You can try this

 $('div.easy_editor').css({'border-width':'9px', 'border-style':'solid', 'border-color':'red'});

The $('div.easy_editor') refers to a collection of all divs that have the class easy editor already. There is no need to use each() unless there was some function that you wanted to run on each. The css() method actually applies to all the divs you find.

The answer is no. Keep in mind that in both cases, mdDate.Kind = DateTimeKind.Unspecified.

Therefore it may be better to do the following:

DateTime myDate = new DateTime(1, 1, 1, 0, 0, 0, DateTimeKind.Utc);

The myDate.Kind property is readonly, so it cannot be changed after the constructor is called.

I have used this one on MySQL, MS Access and SQL Server. The id fields are the fields on wich the tables coincide, not necesarily the primary index.

UPDATE DestTable INNER JOIN SourceTable ON DestTable.idField = SourceTable.idField SET DestTable.Field1 = SourceTable.Field1, DestTable.Field2 = SourceTable.Field2...

$('input[name=test]').click(function () {
    if (this.id == "watch-me") {
        $("#show-me").show('slow');
    } else {
        $("#show-me").hide('slow');
    }
});

Both projects aim to make it easier to deploy & manage applications inside containers in your datacenter or cloud.

In order to deploy applications on top of Mesos, one can use Marathon or Kubernetes for Mesos.

Marathon is a cluster-wide init and control system for running Linux services in cgroups and Docker containers. Marathon has a number of different canary deploy features and is a very mature project.

Marathon runs on top of Mesos, which is a highly scalable, battle tested and flexible resource manager. Marathon is proven to scale and runs in many production environments.

The Mesos and Mesosphere technology stack provides a cloud-like environment for running existing Linux workloads, but it also provides a native environment for building new distributed systems.

Mesos is a distributed systems kernel, with a full API for programming directly against the datacenter. It abstracts underlying hardware (e.g. bare metal or VMs) away and just exposes the resources. It contains primitives for writing distributed applications (e.g. Spark was originally a Mesos App, Chronos, etc.) such as Message Passing, Task Execution, etc. Thus, entirely new applications are made possible. Apache Spark is one example for a new (in Mesos jargon called) framework that was built originally for Mesos. This enabled really fast development - the developers of Spark didn't have to worry about networking to distribute tasks amongst nodes as this is a core primitive in Mesos.

To my knowledge, Kubernetes is not used inside Google in production deployments today. For production, Google uses Omega/Borg, which is much more similar to the Mesos/Marathon model. However the great thing about using Mesos as the foundation is that both Kubernetes and Marathon can run on top of it.

I was having the same problems with the JVM that App Inventor for Android Blocks Editor uses. It sets the heap at 925m max. This is not enough but I couldn't set it more than about 1200m, depending on various random factors on my machine.

I downloaded Nightly, the beta 64-bit browser from Firefox, and also JAVA 7 64 bit version.

I haven't yet found my new heap limit, but I just opened a JVM with a heap size of 5900m. No problem!

I am running Win 7 64 bit Ultimate on a machine with 24gb RAM.

Kotlin way

editText.setOnFocusChangeListener { _, hasFocus ->
    if (!hasFocus) {  }
}

This code is ill-formed:

int&const icr=i;

Reference: C++17 [dcl.ref]/1:

Cv-qualified references are ill-formed except when the cv-qualifiers are introduced through the use of a typedef-name or decltype-specifier, in which case the cv-qualifiers are ignored.

This rule has been present in all standardized versions of C++. Because the code is ill-formed:

• you should not use it, and
• there is no associated behaviour.

The compiler should reject the program; and if it doesn't, the executable's behaviour is completely undefined.

NB: Not sure how none of the other answers mentioned this yet... nobody's got access to a compiler?

Don't forget to return the mapped array , like:

lapsList() {

    return this.state.laps.map((data) => {
      return (
        <View><Text>{data.time}</Text></View>
      )
    })

}

If you see error as follow, you may need to set up your Azure Artifacts Credential, see this Github link, you could either install the credential provider by running a powershell script or manually.

error :   Response status code does not indicate success: 401 (Unauthorized).

Try this:

 function GetDateFormat(controlName) {
        if ($('#' + controlName).val() != "") {      
            var d1 = Date.parse($('#' + controlName).val().toString().replace(/([0-9]+)\/([0-9]+)/,'$2/$1'));
            if (d1 == null) {
                alert('Date Invalid.');
                $('#' + controlName).val("");
            }
                var array = d1.toString('dd-MMM-yyyy');
                $('#' + controlName).val(array);
        }
    }

The RegExp replace .replace(/([0-9]+)\/([0-9]+)/,'$2/$1') change day/month position.

actually I think your code is just fine.. you can save those values as strings (TEXT) just like you did.. (if you want to)

and you probably get the error for the System.currentTimeMillis() that might be too big for INTEGER

Try this:

while read line    
do    
    echo -e |wc -m      
done <abc.txt    

If you have to log all args or your method have one argument, you can simply use getArgs like described in previous answers.

If you have to log a specific arg, you can annoted it and then recover its value like this :

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.PARAMETER)
public @interface Data {
 String methodName() default "";
}

@Aspect
public class YourAspect {

 @Around("...")
 public Object around(ProceedingJoinPoint point) throws Throwable {
  Method method = MethodSignature.class.cast(point.getSignature()).getMethod();
  Object[] args = point.getArgs();
  StringBuilder data = new StringBuilder();
    Annotation[][] parameterAnnotations = method.getParameterAnnotations();
    for (int argIndex = 0; argIndex < args.length; argIndex++) {
        for (Annotation paramAnnotation : parameterAnnotations[argIndex]) {
            if (!(paramAnnotation instanceof Data)) {
                continue;
            }
            Data dataAnnotation = (Data) paramAnnotation;
            if (dataAnnotation.methodName().length() > 0) {
                Object obj = args[argIndex];
                Method dataMethod = obj.getClass().getMethod(dataAnnotation.methodName());
                data.append(dataMethod.invoke(obj));
                continue;
            }
            data.append(args[argIndex]);
        }
    }
 }
}

Examples of use :

public void doSomething(String someValue, @Data String someData, String otherValue) {
    // Apsect will log value of someData param
}

public void doSomething(String someValue, @Data(methodName = "id") SomeObject someData, String otherValue) {
    // Apsect will log returned value of someData.id() method
}

Workstation doesn't have a wireless NIC type, so direct wireless hardware access is out. If you just want to access through the extant host wireless connection, bridging is your answer.

I think the only way to get a wireless NIC dedicated to the VM would be using a USB wireless NIC as a USB-passthrough device on the VM. When you have Workstation running and a USB device plugged in, it should give you an option to change whether that device is connected to the host or to the VM.

Azure Data Studio - free and from Microsoft - offers automatic formatting (ctrl + shift + p while editing -> format document). More information about Azure Data Studio here.

While this is not SSMS, it's great for writing queries, free and an official product from Microsoft. It's even cross-platform. Short story: Just switch to Azure Data Studio to write your queries!

Update: Actually Azure Data Studio is in some way the recommended tool for writing queries (source)

Use Azure Data Studio if you: [..] Are mostly editing or executing queries.

Here is your new friend: QuickSetDNS, by NirSoft, amazing as usual.

It also can be used in command line :) with these advantages over netsh:

• easier syntax, in particular for setting the alternate server
• automatically asks for privilege elevation

Just a few caveats:

• supports only setting of IPv4, not of IPv6
• in command line, the adapter UUID should be used, not the friendly name (e.g. "Local Area Connection") since QuickSetDNS 1.21, connection names are also supported ;)

The fact that you're using a view model has no bearing. The standard way of using PagedList is to store "one page of items" as a ViewBag variable. All you have to determine is what collection constitutes what you'll be paging over. You can't logically page multiple collections at the same time, so assuming you chose Instructors:

ViewBag.OnePageOfItems = myViewModelInstance.Instructors.ToPagedList(pageNumber, 10);

Then, the rest of the standard code works as it always has.

java.util.Arrays.fill()

While waiting for read() or write() to/from a file descriptor return, the process will be put in a special kind of sleep, known as "D" or "Disk Sleep". This is special, because the process can not be killed or interrupted while in such a state. A process waiting for a return from ioctl() would also be put to sleep in this manner.

An exception to this is when a file (such as a terminal or other character device) is opened in O_NONBLOCK mode, passed when its assumed that a device (such as a modem) will need time to initialize. However, you indicated block devices in your question. Also, I have never tried an ioctl() that is likely to block on a fd opened in non blocking mode (at least not knowingly).

How another process is chosen depends entirely on the scheduler you are using, as well as what other processes might have done to modify their weights within that scheduler.

Some user space programs under certain circumstances have been known to remain in this state forever, until rebooted. These are typically grouped in with other "zombies", but the term would not be correct as they are not technically defunct.

Stackoverflow uses such function to determine the age of a user.

Calculate age in C#

The given answer is

DateTime now = DateTime.Today;
int age = now.Year - bday.Year;
if (now < bday.AddYears(age)) age--;

So your helper method would look like

public static string Age(this HtmlHelper helper, DateTime birthday)
{
    DateTime now = DateTime.Today;
    int age = now.Year - birthday.Year;
    if (now < birthday.AddYears(age)) age--;

    return age.ToString();
}

Today, I use a different version of this function to include a date of reference. This allow me to get the age of someone at a future date or in the past. This is used for our reservation system, where the age in the future is needed.

public static int GetAge(DateTime reference, DateTime birthday)
{
    int age = reference.Year - birthday.Year;
    if (reference < birthday.AddYears(age)) age--;

    return age;
}

Here is an example

                            GHI             Temp  Power Day_Type
2016-03-15 06:00:00 -7.99999952505459e-7    18.3    0   NaN
2016-03-15 06:01:00 -7.99999952505459e-7    18.2    0   NaN
2016-03-15 06:02:00 -7.99999952505459e-7    18.3    0   NaN
2016-03-15 06:03:00 -7.99999952505459e-7    18.3    0   NaN
2016-03-15 06:04:00 -7.99999952505459e-7    18.3    0   NaN

but if this is all string values...as was in my case... Convert the desired columns to floats:

df_inv_29['GHI'] = df_inv_29.GHI.astype(float)
df_inv_29['Temp'] = df_inv_29.Temp.astype(float)
df_inv_29['Power'] = df_inv_29.Power.astype(float)

Your dataframe will now have float values :-)

I use Apache server, so I've used mod_proxy module. Enable modules:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Then add:

ProxyPass /your-proxy-url/ http://service-url:serviceport/

Finally, pass proxy-url to your script.

You should be able to accomplish this by using location.href

if(window.location.hostname == "www.myweb.com"){
   window.location.href = window.location.href + "?single";
}

Many of the answers listed here have inherent issues:

• Checking for test-keys is correlated with root access but doesn't necessarily guarantee it
• "PATH" directories should be derived from the actual "PATH" environment variable instead of being hard coded
• The existence of the "su" executable doesn't necessarily mean the device has been rooted
• The "which" executable may or may not be installed, and you should let the system resolve its path if possible
• Just because the SuperUser app is installed on the device does not mean the device has root access yet

The RootTools library from Stericson seems to be checking for root more legitimately. It also has lots of extra tools and utilities so I highly recommend it. However, there's no explanation of how it specifically checks for root, and it may be a bit heavier than most apps really need.

I've made a couple of utility methods that are loosely based on the RootTools library. If you simply want to check if the "su" executable is on the device you can use the following method:

public static boolean isRootAvailable(){
    for(String pathDir : System.getenv("PATH").split(":")){
        if(new File(pathDir, "su").exists()) {
            return true;
        }
    }
    return false;
}

This method simply loops through the directories listed in the "PATH" environment variable and checks if a "su" file exists in one of them.

In order to truly check for root access the "su" command must actually be run. If an app like SuperUser is installed, then at this point it may ask for root access, or if its already been granted/denied a toast may be shown indicating whether access was granted/denied. A good command to run is "id" so that you can verify that the user id is in fact 0 (root).

Here's a sample method to determine whether root access has been granted:

public static boolean isRootGiven(){
    if (isRootAvailable()) {
        Process process = null;
        try {
            process = Runtime.getRuntime().exec(new String[]{"su", "-c", "id"});
            BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String output = in.readLine();
            if (output != null && output.toLowerCase().contains("uid=0"))
                return true;
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (process != null)
                process.destroy();
        }
    }

    return false;
}

It's important to actually test running the "su" command because some emulators have the "su" executable pre-installed, but only allow certain users to access it like the adb shell.

It's also important to check for the existence of the "su" executable before trying to run it, because android has been known to not properly dispose of processes that try to run missing commands. These ghost processes can run up memory consumption over time.

os.system() returns the (encoded) process exit value. 0 means success:

On Unix, the return value is the exit status of the process encoded in the format specified for wait(). Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent.

The output you see is written to stdout, so your console or terminal, and not returned to the Python caller.

If you wanted to capture stdout, use subprocess.check_output() instead:

x = subprocess.check_output(['whoami'])

replace

include fastcgi_params;

with

include fastcgi.conf;

and remove fastcgi_param SCRIPT_FILENAME ... in nginx.conf

Set automatic dimension for row height & estimated row height and ensure following steps:

@IBOutlet weak var table: UITableView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Set automatic dimensions for row height
    // Swift 4.2 onwards
    table.rowHeight = UITableView.automaticDimension
    table.estimatedRowHeight = UITableView.automaticDimension


    // Swift 4.1 and below
    table.rowHeight = UITableViewAutomaticDimension
    table.estimatedRowHeight = UITableViewAutomaticDimension

}



// UITableViewAutomaticDimension calculates height of label contents/text
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    // Swift 4.2 onwards
    return UITableView.automaticDimension

    // Swift 4.1 and below
    return UITableViewAutomaticDimension
}

For Example: if you have a label in your UITableviewCell then,

• Set number of lines = 0 (& line break mode = truncate tail)
• Set all constraints (top, bottom, right left) with respect to its superview/ cell container.
• Optional: Set minimum height for label, if you want minimum vertical area covered by label, even if there is no data.

Here is sample label with dynamic height constraints.

In my case I had to start a list of exclude extensions from the second line because xcopy ignored the first line.

git pull

That simply fixed it for me :)

<button my-directive="push">Push to Go</button>

app.directive("myDirective", function() {
    return {
        restrict : "A",
         link: function(scope, elm, attrs) {
                elm.bind('click', function(event) {

                    alert("You pressed button: " + event.target.getAttribute('my-directive'));
                });
        }
    };
});

here is what I did

I'm using directive as html attribute and I passed parameter as following in my HTML file. my-directive="push" And from the directive I retrieved it from the Mouse-click event object. event.target.getAttribute('my-directive').

You're probably aware of this, but just in case: it's much easier to just type shutdown -r (or whatever command you like) into the "Run" box and hit enter.

Saves leaving batch files lying around everywhere.

Something like this?

function delete_folder($folder) {
    $glob = glob($folder);
    foreach ($glob as $g) {
        if (!is_dir($g)) {
            unlink($g);
        } else {
            delete_folder("$g/*");
            rmdir($g);
        }
    }
}

inline bool IsNan(float f)
{
    const uint32 u = *(uint32*)&f;
    return (u&0x7F800000) == 0x7F800000 && (u&0x7FFFFF);    // Both NaN and qNan.
}

inline bool IsNan(double d)
{
    const uint64 u = *(uint64*)&d;
    return (u&0x7FF0000000000000ULL) == 0x7FF0000000000000ULL && (u&0xFFFFFFFFFFFFFULL);
}

This works if sizeof(int) is 4 and sizeof(long long) is 8.

During run time it is only comparison, castings do not take any time. It just changes comparison flags configuration to check equality.

How to handle authentication in a RESTful Client-Server architecture is a matter of debate.

Commonly, it can be achieved, in the SOA over HTTP world via:

• HTTP basic auth over HTTPS;
• Cookies and session management;
• Token in HTTP headers (e.g. OAuth 2.0 + JWT);
• Query Authentication with additional signature parameters.

You'll have to adapt, or even better mix those techniques, to match your software architecture at best.

Each authentication scheme has its own PROs and CONs, depending on the purpose of your security policy and software architecture.

HTTP basic auth over HTTPS

This first solution, based on the standard HTTPS protocol, is used by most web services.

GET /spec.html HTTP/1.1
Host: www.example.org
Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==

It's easy to implement, available by default on all browsers, but has some known drawbacks, like the awful authentication window displayed on the Browser, which will persist (there is no LogOut-like feature here), some server-side additional CPU consumption, and the fact that the user-name and password are transmitted (over HTTPS) into the Server (it should be more secure to let the password stay only on the client side, during keyboard entry, and be stored as secure hash on the Server).

We may use Digest Authentication, but it requires also HTTPS, since it is vulnerable to MiM or Replay attacks, and is specific to HTTP.

Session via Cookies

To be honest, a session managed on the Server is not truly Stateless.

One possibility could be to maintain all data within the cookie content. And, by design, the cookie is handled on the Server side (Client, in fact, does even not try to interpret this cookie data: it just hands it back to the server on each successive request). But this cookie data is application state data, so the client should manage it, not the server, in a pure Stateless world.

GET /spec.html HTTP/1.1
Host: www.example.org
Cookie: theme=light; sessionToken=abc123

The cookie technique itself is HTTP-linked, so it's not truly RESTful, which should be protocol-independent, IMHO. It is vulnerable to MiM or Replay attacks.

Granted via Token (OAuth2)

An alternative is to put a token within the HTTP headers so that the request is authenticated. This is what OAuth 2.0 does, for instance. See the RFC 6749:

 GET /resource/1 HTTP/1.1
 Host: example.com
 Authorization: Bearer mF_9.B5f-4.1JqM

In short, this is very similar to a cookie and suffers to the same issues: not stateless, relying on HTTP transmission details, and subject to a lot of security weaknesses - including MiM and Replay - so is to be used only over HTTPS. Typically, a JWT is used as a token.

Query Authentication

Query Authentication consists in signing each RESTful request via some additional parameters on the URI. See this reference article.

It was defined as such in this article:

All REST queries must be authenticated by signing the query parameters sorted in lower-case, alphabetical order using the private credential as the signing token. Signing should occur before URL encoding the query string.

This technique is perhaps the more compatible with a Stateless architecture, and can also be implemented with a light session management (using in-memory sessions instead of DB persistence).

For instance, here is a generic URI sample from the link above:

GET /object?apiKey=Qwerty2010

should be transmitted as such:

GET /object?timestamp=1261496500&apiKey=Qwerty2010&signature=abcdef0123456789

The string being signed is /object?apikey=Qwerty2010&timestamp=1261496500 and the signature is the SHA256 hash of that string using the private component of the API key.

Server-side data caching can be always available. For instance, in our framework, we cache the responses at the SQL level, not at the URI level. So adding this extra parameter doesn't break the cache mechanism.

See this article for some details about RESTful authentication in our client-server ORM/SOA/MVC framework, based on JSON and REST. Since we allow communication not only over HTTP/1.1, but also named pipes or GDI messages (locally), we tried to implement a truly RESTful authentication pattern, and not rely on HTTP specificity (like header or cookies).

Later Note: adding a signature in the URI can be seen as bad practice (since for instance it will appear in the http server logs) so it has to be mitigated, e.g. by a proper TTL to avoid replays. But if your http logs are compromised, you will certainly have bigger security problems.

In practice, the upcoming MAC Tokens Authentication for OAuth 2.0 may be a huge improvement in respect to the "Granted by Token" current scheme. But this is still a work in progress and is tied to HTTP transmission.

Conclusion

It's worth concluding that REST is not only HTTP-based, even if, in practice, it's also mostly implemented over HTTP. REST can use other communication layers. So a RESTful authentication is not just a synonym of HTTP authentication, whatever Google answers. It should even not use the HTTP mechanism at all but shall be abstracted from the communication layer. And if you use HTTP communication, thanks to the Let's Encrypt initiative there is no reason not to use proper HTTPS, which is required in addition to any authentication scheme.

In this case, using WebView#loadDataWithBaseUrl() is better than WebView#loadUrl()!

webView.loadDataWithBaseURL(url, 
        data,
        "text/html",
        "utf-8",
        null);

url: url/path String pointing to the directory all your JavaScript files and html links have their origin. If null, it's about:blank. data: String containing your hmtl file, read with BufferedReader for example

More info: WebView.loadDataWithBaseURL(java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String)

LESS has guard expressions for mixins, not individual attributes.

So you'd create a mixin like this:

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

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

Probably not what you want to hear, but a "feeds" table would be a great middleman for this sort of transaction, giving you a denormalized way of pivoting to all these data with a polymorphic relationship.

You could build it like this:

<?php

Schema::create('feeds', function($table) {
    $table->increments('id');
    $table->timestamps();
    $table->unsignedInteger('user_id');
    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    $table->morphs('target'); 
});

Build the feed model like so:

<?php

class Feed extends Eloquent
{
    protected $fillable = ['user_id', 'target_type', 'target_id'];

    public function user()
    {
        return $this->belongsTo('User');
    }

    public function target()
    {
        return $this->morphTo();
    }
}

Then keep it up to date with something like:

<?php

Vote::created(function(Vote $vote) {
    $target_type = 'Vote';
    $target_id   = $vote->id;
    $user_id     = $vote->user_id;

    Feed::create(compact('target_type', 'target_id', 'user_id'));
});

You could make the above much more generic/robust—this is just for demonstration purposes.

At this point, your feed items are really easy to retrieve all at once:

<?php

Feed::whereIn('user_id', $my_friend_ids)
    ->with('user', 'target')
    ->orderBy('created_at', 'desc')
    ->get();

function test(string) {
    return ! string.match(/abc|def/);
}

The correct answer is this (example version):

• In parent pom.xml you should have (not inside properties):

  <version>0.0.1-SNAPSHOT</version>
  

• In all child modules you should have:

  <parent>
      <groupId>com.vvirlan</groupId>
      <artifactId>grafiti</artifactId>
      <version>0.0.1-SNAPSHOT</version>
  </parent>
  

So it is hardcoded.

Now, to update the version you do this:

mvn versions:set -DnewVersion=0.0.2-SNAPSHOT
mvn versions:commit # Necessary to remove the backup file pom.xml

and all your 400 modules will have the parent version updated.

Since I spent a long time solving a similar problem, I'm answering to share my experience. My problem was the same, to know, getting many checkboxes value after a specified event has been triggered. I tried a lot of solutions but for me the sexiest is using ViewChildren.

import { ViewChildren, QueryList } from '@angular/core';

/** Get handle on cmp tags in the template */
@ViewChildren('cmp') components: QueryList<any>;

ngAfterViewInit(){
    // print array of CustomComponent objects
    console.log(this.components.toArray());
}

Don't use NULL, C++ allows you to use the unadorned 0 instead:

previous = 0;
next = 0;

And, as at C++11, you generally shouldn't be using either NULL or 0 since it provides you with nullptr of type std::nullptr_t, which is better suited to the task.

Until now, I was using cmd processes in order to extract an .iso file, copy it into a temporary path from server and extracted on a usb stick. Recently I've found that this is working perfectly with .iso's that are less than 10Gb. For a iso like 29Gb this method gets stuck somehow.

    public void ExtractArchive()
    {
        try
        {

            try
            {
                Directory.Delete(copyISOLocation.OutputPath, true); 
            }
            catch (Exception e) when (e is IOException || e is UnauthorizedAccessException)
            {
            }

            Process cmd = new Process();
            cmd.StartInfo.FileName = "cmd.exe";
            cmd.StartInfo.RedirectStandardInput = true;
            cmd.StartInfo.RedirectStandardOutput = true;
            cmd.StartInfo.CreateNoWindow = true;
            cmd.StartInfo.UseShellExecute = false;
            cmd.StartInfo.WindowStyle = ProcessWindowStyle.Normal;

            //stackoverflow
            cmd.StartInfo.Arguments = "-R";

            cmd.Disposed += (sender, args) => {
                Console.WriteLine("CMD Process disposed");
            };
            cmd.Exited += (sender, args) => {
                Console.WriteLine("CMD Process exited");
            };
            cmd.ErrorDataReceived += (sender, args) => {
                Console.WriteLine("CMD Process error data received");
                Console.WriteLine(args.Data);
            };
            cmd.OutputDataReceived += (sender, args) => {
                Console.WriteLine("CMD Process Output data received");
                Console.WriteLine(args.Data);
            };

            //stackoverflow


            cmd.Start();

            cmd.StandardInput.WriteLine("C:");
            //Console.WriteLine(cmd.StandardOutput.Read());
            cmd.StandardInput.Flush();

            cmd.StandardInput.WriteLine("cd C:\\\"Program Files (x86)\"\\7-Zip\\");
            //Console.WriteLine(cmd.StandardOutput.ReadToEnd());
            cmd.StandardInput.Flush();

            cmd.StandardInput.WriteLine(string.Format("7z.exe x -o{0} {1}", copyISOLocation.OutputPath, copyISOLocation.TempIsoPath));
            //Console.WriteLine(cmd.StandardOutput.ReadToEnd());
            cmd.StandardInput.Flush();
            cmd.StandardInput.Close();

I would suggest using conda. Conda is an anconda specific package manager. If you want to know more about conda, read the conda docs.

Using conda in the command line, the command below would install scipy 0.17.

conda install scipy=0.17.0

To answer the WHY in your question:

Because the equality operator can only be applied to simple variable types, such as floats, ints, or chars, and not to more sophisticated types, such as structures or arrays. To determine if two strings are equal, you must explicitly compare the two character strings character by character.

Since you asked for a way to complete this within an HTML page I am answering this. I feel there is no need to mention the severe warnings and implications that would go along with this .. I trust you know the security of your .py script better than I do :-)

I would use the .ajax() function in the jQuery library. This will allow you to call your Python script as long as the script is in the publicly accessible html directory ... That said this is the part where I tell you to heed security precautions ...

<!DOCTYPE html>
<html>
  <head>    
  </head>
  <body>
    <input type="button" id='script' name="scriptbutton" value=" Run Script " onclick="goPython()">

    <script src="http://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous"></script>

    <script>
        function goPython(){
            $.ajax({
              url: "MYSCRIPT.py",
             context: document.body
            }).done(function() {
             alert('finished python script');;
            });
        }
    </script>
  </body>
</html>

In addition .. It's worth noting that your script is going to have to have proper permissions for, say, the www-data user to be able to run it ... A chmod, and/or a chown may be necessary.

You could remove the folder and update the parent directory before committing:

rm -r some_dir

svn update some_dir_parent

Use Collections.list(iterator).stream()...

A quick update to Michael's excellent answer above.

For Rails 4.0+ you need to put your sort in a block like this:

class Book < ActiveRecord::Base
  default_scope { order('created_at DESC') }
end

Notice that the order statement is placed in a block denoted by the curly braces.

They changed it because it was too easy to pass in something dynamic (like the current time). This removes the problem because the block is evaluated at runtime. If you don't use a block you'll get this error:

Support for calling #default_scope without a block is removed. For example instead of default_scope where(color: 'red'), please use default_scope { where(color: 'red') }. (Alternatively you can just redefine self.default_scope.)

As @Dan mentions in his comment below, you can do a more rubyish syntax like this:

class Book < ActiveRecord::Base
  default_scope { order(created_at: :desc) }
end

or with multiple columns:

class Book < ActiveRecord::Base
  default_scope { order({begin_date: :desc}, :name) }
end

Thanks @Dan!

Some time This Code Not worked proper

Same-origin policy

https://en.wikipedia.org/wiki/Same-origin_policy

https://en.wikipedia.org/wiki/Cross-origin_resource_sharing

problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is [CORS][1]. 

Ref : https://superuser.com/questions/773719/how-do-all-of-these-save-video-from-youtube-services-work/773998#773998

url_encoded_fmt_stream_map // traditional: contains video and audio stream
adaptive_fmts              // DASH: contains video or audio stream

Each of these is a comma separated array of what I would call "stream objects". Each "stream object" will contain values like this

url  // direct HTTP link to a video
itag // code specifying the quality
s    // signature, security measure to counter downloading

Each URL will be encoded so you will need to decode them. Now the tricky part.

YouTube has at least 3 security levels for their videos

unsecured // as expected, you can download these with just the unencoded URL
s         // see below
RTMPE     // uses "rtmpe://" protocol, no known method for these

The RTMPE videos are typically used on official full length movies, and are protected with SWF Verification Type 2. This has been around since 2011 and has yet to be reverse engineered.

The type "s" videos are the most difficult that can actually be downloaded. You will typcially see these on VEVO videos and the like. They start with a signature such as

AA5D05FA7771AD4868BA4C977C3DEAAC620DE020E.0F421820F42978A1F8EAFCDAC4EF507DB5 Then the signature is scrambled with a function like this

function mo(a) {
  a = a.split("");
  a = lo.rw(a, 1);
  a = lo.rw(a, 32);
  a = lo.IC(a, 1);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 44);
  return a.join("")
}

This function is dynamic, it typically changes every day. To make it more difficult the function is hosted at a URL such as

http://s.ytimg.com/yts/jsbin/html5player-en_US-vflycBCEX.js

this introduces the problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is CORS. With CORS, s.ytimg.com could add this header

Access-Control-Allow-Origin: http://www.youtube.com

and it would allow the JavaScript to download from www.youtube.com. Of course they do not do this. A workaround for this workaround is to use a CORS proxy. This is a proxy that responds with the following header to all requests

Access-Control-Allow-Origin: *

So, now that you have proxied your JS file, and used the function to scramble the signature, you can use that in the querystring to download a video.

From here: http://www.anddev.org/working_with_files-t115.html

//Writing a file...  



try { 
       // catches IOException below

import operator
sorted_x = sorted(x, key=operator.attrgetter('score'))

if you want to sort x in-place, you can also:

x.sort(key=operator.attrgetter('score'))

System.out.println("Managers choice this week" + anyItem + "our recommendation to you");

You havent the variable anyItem initialized or even declared.

This code: + anyItem +

means get value of toString method of Object anyItem

The second thing why this wont work. You have System.out.print after return statement. Program could never reach tha line.

You probably want something like:

public Item anyItem() {
    int index = randomGenerator.nextInt(catalogue.size());
    System.out.println("Managers choice this week" + catalogue.get(index) + "our recommendation to you");
    return catalogue.get(index);

}

btw: in Java its convetion to place the curly parenthesis on the same line as the declaration of the function.

No promises are just wrapper on callbacks

example You can use javascript native promises with node js

Check out querystring.

You can use it as follows:

var querystring = require('querystring');
axios.post('http://something.com/', querystring.stringify({ foo: 'bar' }));

As of Jan 2018 the latest URL is:

urllib went through some changes in Python3 and can now be imported from the parse submodule

I have tried this with and without the WRITE_INTERNAL_STORAGE permission.

There is no WRITE_INTERNAL_STORAGE permission in Android.

How do I create this file for writing?

You don't, except perhaps on a rooted device, if your app is running with superuser privileges. You are trying to write to the root of internal storage, which apps do not have access to.

Please use the version of the FileOutputStream constructor that takes a File object. Create that File object based off of some location that you can write to, such as:

• getFilesDir() (called on your Activity or other Context)
• getExternalFilesDir() (called on your Activity or other Context)

The latter will require WRITE_EXTERNAL_STORAGE as a permission.

Is there an easier way than writing it to a file then reading from it again?

You can temporarily put it in a static data member.

because many people don't have SD card slots

"SD card slots" are irrelevant, by and large. 99% of Android device users will have external storage -- the exception will be 4+ year old devices where the user removed their SD card. Devices manufactured since mid-2010 have external storage as part of on-board flash, not as removable media.

For this specific use-case using try..except..else is the cleanest solution, the else clause will be executed if no exception was raised.

NOTE: The else clause must follow all except clauses

for i in iterator:
    try:
        # Do something.
    except:
        # Handle exception
    else:
        # Continue doing something

For student level programs, Clang has the benefit that it is, by default, stricter wrt. the C standard. For example, the following K&R version of Hello World is accepted without warning by GCC, but rejected by Clang with some pretty descriptive error messages:

main()
{
    puts("Hello, world!");
}

With GCC, you have to give it -Werror to get it to really make a point about this not being a valid C89 program. Also, you still need to use c99 or gcc -std=c99 to get the C99 language.

this is one:

ls -l . | egrep -c '^-'

Note:

ls -1 | wc -l

Which means: ls: list files in dir

-1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

|: pipe output onto...

wc: "wordcount"

-l: count lines.

I have experience with SharePoint 2007, 2010 and there is a limit of the length URL you can create from the server side in this case SharePoint, so it depends mostly on, 1) the client (browser, version, and OS) and 2) the server technology, IIS, Apache, etc.

Check the formatting (right click on cell, Format Cells). Under tab "Number" the category should be "General". If, for instance, it's "Text" anything typed in would be treated as a string rather than a formula to be interpreted.

An aggregate function requires a GROUP BY in standard SQL

This is "Get minimum date per title" in plain language

SELECT title, MIN(date) FROM table GROUP BY title

Most RDBMS and the standard require that column is either in the GROUP BY or in a functions (MIN, COUNT etc): MySQL is the notable exception with some extensions that give unpredictable behaviour

In my development setup – missing a proper Groovy editor – a great deal of Jenkinsfile issues originates from simple syntax errors. To tackle this issue, you can validate the Jenkinsfile against your Jenkins instance (running at $JENKINS_HTTP_URL):

curl -X POST -H $(curl '$JENKINS_HTTP_URL/crumbIssuer/api/xml?xpath=concat(//crumbRequestField,":",//crumb)') -F "jenkinsfile=<Jenkinsfile" $JENKINS_HTTP_URL/pipeline-model-converter/validate

The above command is a slightly modified version from https://github.com/jenkinsci/pipeline-model-definition-plugin/wiki/Validating-(or-linting)-a-Declarative-Jenkinsfile-from-the-command-line

Creating a new attribute class is a good suggestion. In my case, I wanted to specify 'default(DateTime)' or 'DateTime.MinValue' so that the Newtonsoft.Json serializer would ignore DateTime members without real values.

[JsonProperty( DefaultValueHandling = DefaultValueHandling.Ignore )]
[DefaultDateTime]
public DateTime EndTime;

public class DefaultDateTimeAttribute : DefaultValueAttribute
{
    public DefaultDateTimeAttribute()
        : base( default( DateTime ) ) { }

    public DefaultDateTimeAttribute( string dateTime )
        : base( DateTime.Parse( dateTime ) ) { }
}

Without the DefaultValue attribute, the JSON serializer would output "1/1/0001 12:00:00 AM" even though the DefaultValueHandling.Ignore option was set.

I'm guessing that you meant to do this:

msg['Subject'] = "Auto Hella Restart Report " + sys.argv[1]
# To concatenate strings in python, use       ^ 

Quick Easy Process in Visual Studio

Drag and Drop the file with .ts extension from solution window to editor, it will generate inline reference code like..

/// <reference path="../../components/someclass.ts"/>

If the forked repo is protected so you can't push directly into it, and your goal is to make changes to their foo, then you need to get their branch foo into your repo like so:

git remote add protected_repo https://github.com/theirusername/their_repo.git
git fetch protected_repo 
git checkout --no-track protected_repo/foo

Now you have a local copy of foo with no upstream associated to it. You can commit changes to it (or not) and then push your foo to your own remote repo.

git push --set-upstream origin foo

Now foo is in your repo on GitHub and your local foo is tracking it. If they continue to make changes to foo you can fetch theirs and merge into your foo.

git checkout foo 
git fetch protected_repo
git merge protected_repo/foo

The top command also contains a field to display the number of page faults for a process. The process with maximum page faults would be the process which is swapping most. For long running daemons it might be that they incur large number of page faults at the beginning and the number does not increase later on. So we need to observe whether the page faults is increasing.

Try

SELECT * FROM table WHERE arr @> ARRAY['s']::varchar[]

I have a couple of suggestions:

1. First of all, you seem to be using API 4 as your target. AFAIK, it's good practice to always compile against the latest SDK and setup your android:minSdkVersion accordingly.

2. With that in mind, remember that android:required attribute was added in API 5:

The feature declaration can include an android:required=["true" | "false"] attribute (if you are compiling against API level 5 or higher), which lets you specify whether the application (...)

Thus, I'd suggest that you compile against SDK 15, set targetSdkVersion to 15 as well, and provide that functionality.

It also shows here, on the Play site, as incompatible with any device that I have that is (coincidence?) Gingerbread (Galaxy Ace and Galaxy Y here). But it shows as compatible with my Galaxy Tab 10.1 (Honeycomb), Nexus S and Galaxy Nexus (both on ICS).

That also left me wondering, and this is a very wild guess, but since android.hardware.faketouch is API11+, why don't you try removing it just to see if it works? Or perhaps that's all related anyway, since you're trying to use features (faketouch) and the required attribute that are not available in API 4. And in this case you should compile against the latest API.

I would try that first, and remove the faketouch requirement only as last resort (of course) --- since it works when developing, I'd say it's just a matter of the compiled app not recognizing the feature (due to the SDK requirements), thus leaving unexpected filtering issues on Play.

Sorry if this guess doesn't answer your question, but it's very difficult to diagnose those kind of problems and pinpoint the solution without actually testing. Or at least for me without all the proper knowledge of how Play really filters apps.

Good luck.

Simply :first works for me, why isn't this mentioned yet?

I know what you mean, you want to trigger handleChange by click button.

But modify state value will not trigger onChange event, because onChange event is a form element event.

Make sure those two types are nullable DateTime

var lastPostDate = reader[3] == DBNull.Value ?
                                        null : 
                                   (DateTime?) Convert.ToDateTime(reader[3]);

• Usage of DateTime? instead of Nullable<DateTime> is a time saver...
• Use better indent of the ? expression like I did.

I have found this excellent explanations in Eric Lippert blog:

The specification for the ?: operator states the following:

The second and third operands of the ?: operator control the type of the conditional expression. Let X and Y be the types of the second and third operands. Then,

• If X and Y are the same type, then this is the type of the conditional expression.

• Otherwise, if an implicit conversion exists from X to Y, but not from Y to X, then Y is the type of the conditional expression.

• Otherwise, if an implicit conversion exists from Y to X, but not from X to Y, then X is the type of the conditional expression.

• Otherwise, no expression type can be determined, and a compile-time error occurs.

The compiler doesn't check what is the type that can "hold" those two types.

In this case:

• null and DateTime aren't the same type.
• null doesn't have an implicit conversion to DateTime
• DateTime doesn't have an implicit conversion to null

So we end up with a compile-time error.

To access the tomcat manager from different machine you have to follow bellow steps:

1. Update conf/tomcat-users.xml file with user and some roles:

<role rolename="manager-gui"/>
 <role rolename="manager-script"/>
 <role rolename="manager-jmx"/>
 <role rolename="manager-status"/>
 <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status"/>

Here admin user is assigning roles="manager-gui,manager-script,manager-jmx,manager-status".

Here tomcat user and password is : admin

2. Update webapps/manager/META-INF/context.xml file (Allowing IP address):

Default configuration:

<Context antiResourceLocking="false" privileged="true" >
  
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
  
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>

Here in Valve it is allowing only local machine IP start with 127.\d+.\d+.\d+ .

2.a : Allow specefic IP:

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|YOUR.IP.ADDRESS.HERE" />

Here you just replace |YOUR.IP.ADDRESS.HERE with your IP address

2.b : Allow all IP:

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow=".*" />

Here using allow=".*" you are allowing all IP.

Thanks :)

I just wanted to mention something a little strange to me when I first encountered this.

I needed to initialize a private static data member in a template class.

in the .h or .hpp, it looks something like this to initialize a static data member of a template class:

template<typename T>
Type ClassName<T>::dataMemberName = initialValue;
