Another way to link Angular Paginator with the data table using Slice Pipe.Here data is fetched only once from server.

View:

 <div class="col-md-3" *ngFor="let productObj of productListData | 
     slice: lowValue : highValue">
       //actual data dispaly  
 </div>

<mat-paginator [length]="productListData.length" [pageSize]="pageSize" 
   (page)="pageEvent = getPaginatorData($event)">
</mat-paginator> 

Component

    pageIndex:number = 0;
    pageSize:number = 50;
    lowValue:number = 0;
    highValue:number = 50;       

  getPaginatorData(event){
     console.log(event);
     if(event.pageIndex === this.pageIndex + 1){
        this.lowValue = this.lowValue + this.pageSize;
        this.highValue =  this.highValue + this.pageSize;
       }
    else if(event.pageIndex === this.pageIndex - 1){
       this.lowValue = this.lowValue - this.pageSize;
       this.highValue =  this.highValue - this.pageSize;
      }   
       this.pageIndex = event.pageIndex;
 }

@d123546 I faced the same issue and got it working now using ngAfterContentInit (Lifecycle Hook) in the component like this :

import { Component, OnInit, AfterContentInit } from '@angular/core';
import { Router } from '@angular/router';
import { ScriptService } from '../../script.service';

@Component({
    selector: 'app-players-list',
    templateUrl: './players-list.component.html',
    styleUrls: ['./players-list.component.css'],
    providers: [ ScriptService ]
})
export class PlayersListComponent implements OnInit, AfterContentInit {

constructor(private router: Router, private script: ScriptService) {
}

ngOnInit() {
}

ngAfterContentInit() {
    this.script.load('filepicker', 'rangeSlider').then(data => {
    console.log('script loaded ', data);
    }).catch(error => console.log(error));
}

This is because of the combination of two things:

• tsconfig not having any files section. From http://www.typescriptlang.org/docs/handbook/tsconfig-json.html

  If no "files" property is present in a tsconfig.json, the compiler defaults to including all files in the containing directory and subdirectories. When a "files" property is specified, only those files are included.

• Including typescript as an npm dependency : node_modules/typescript/ This means that all of typescript gets included .... there is an implicitly included lib.d.ts in your project anyways (http://basarat.gitbook.io/typescript/content/docs/types/lib.d.ts.html) and its conflicting with the one that ships with the NPM version of typescript.

Fix

Either list files or include explicitly https://basarat.gitbook.io/typescript/docs/project/files.html

By default, JNDI is disabled in embedded Tomcat which is causing the NoInitialContextException. You need to call Tomcat.enableNaming() to enable it. The easiest way to do that is with a TomcatEmbeddedServletContainer subclass:

@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
    return new TomcatEmbeddedServletContainerFactory() {

        @Override
        protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
                Tomcat tomcat) {
            tomcat.enableNaming();
            return super.getTomcatEmbeddedServletContainer(tomcat);
        }
    };
}

If you take this approach, you can also register the DataSource in JNDI by overriding the postProcessContext method in your TomcatEmbeddedServletContainerFactory subclass.

context.getNamingResources().addResource adds the resource to the java:comp/env context so the resource's name should be jdbc/mydatasource not java:comp/env/mydatasource.

Tomcat uses the thread context class loader to determine which JNDI context a lookup should be performed against. You're binding the resource into the web app's JNDI context so you need to ensure that the lookup is performed when the web app's class loader is the thread context class loader. You should be able to achieve this by setting lookupOnStartup to false on the jndiObjectFactoryBean. You'll also need to set expectedType to javax.sql.DataSource:

<bean class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/jdbc/mydatasource"/>
    <property name="expectedType" value="javax.sql.DataSource"/>
    <property name="lookupOnStartup" value="false"/>
</bean>

This will create a proxy for the DataSource with the actual JNDI lookup being performed on first use rather than during application context startup.

The approach described above is illustrated in this Spring Boot sample.

A somewhat late answer, but with pandas, it is possible to get directly a column of an excel file:

import pandas

df = pandas.read_excel('sample.xls')
#print the column names
print df.columns
#get the values for a given column
values = df['Arm_id'].values
#get a data frame with selected columns
FORMAT = ['Arm_id', 'DSPName', 'Pincode']
df_selected = df[FORMAT]

Make sure you have installed xlrd and pandas:

pip install pandas xlrd

You can solve this with a one-liner( errStringified ) in plain javascript:

var error = new Error('simple error message');
var errStringified = (err => JSON.stringify(Object.getOwnPropertyNames(Object.getPrototypeOf(err)).reduce(function(accumulator, currentValue) { return accumulator[currentValue] = err[currentValue], accumulator}, {})))(error);
console.log(errStringified);

It works with DOMExceptions as well.

One pretty easy way to work around this issue is to append a trailing slash ...

e.g.:

use :

/somepath/filename.jpg/

instead of:

/somepath/filename.jpg

You wont be able to do this from the client side because of the Same Origin Policy set by the browsers. You wont be able to get much information from the iFrame other than basic properties like its width and height.

Also, google sets in its response header an 'X-Frame-Options' of SAMEORIGIN.

Even if you did an ajax call to google you wont be able to inspect the response because the browser enforcing Same Origin Policy.

So, the only option is to make the request from your server to see if you can display the site in your IFrame.

So, on your server.. your web app would make a request to www.google.com and then inspect the response to see if it has a header argument of X-Frame-Options. If it does exist then you know the IFrame will error.

DMitryG's code "get the return value of the underlying MessageBox" has a bug so the timerResult is never actually correctly returned (MessageBox.Show call returns AFTER OnTimerElapsed completes). My fix is below:

public class TimedMessageBox {
    System.Threading.Timer _timeoutTimer;
    string _caption;
    DialogResult _result;
    DialogResult _timerResult;
    bool timedOut = false;

    TimedMessageBox(string text, string caption, int timeout, MessageBoxButtons buttons = MessageBoxButtons.OK, DialogResult timerResult = DialogResult.None)
    {
        _caption = caption;
        _timeoutTimer = new System.Threading.Timer(OnTimerElapsed,
            null, timeout, System.Threading.Timeout.Infinite);
        _timerResult = timerResult;
        using(_timeoutTimer)
            _result = MessageBox.Show(text, caption, buttons);
        if (timedOut) _result = _timerResult;
    }

    public static DialogResult Show(string text, string caption, int timeout, MessageBoxButtons buttons = MessageBoxButtons.OK, DialogResult timerResult = DialogResult.None) {
        return new TimedMessageBox(text, caption, timeout, buttons, timerResult)._result;
    }

    void OnTimerElapsed(object state) {
        IntPtr mbWnd = FindWindow("#32770", _caption); // lpClassName is #32770 for MessageBox
        if(mbWnd != IntPtr.Zero)
            SendMessage(mbWnd, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
        _timeoutTimer.Dispose();
        timedOut = true;
    }

    const int WM_CLOSE = 0x0010;
    [System.Runtime.InteropServices.DllImport("user32.dll", SetLastError = true, CharSet = System.Runtime.InteropServices.CharSet.Auto)]
    static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
    [System.Runtime.InteropServices.DllImport("user32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)]
    static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);
}

Sometime we need to compile one single file out of thousand files to fix the problem. In such a case, One can create same folder structure like class path, decompile the file into java or copy java file from source code. Make required changes, compile one particular file into class with all dependency/classes in place and finally replace the class file. Finally restart the container. Once war is exploded file will not be replaced.

Instead of drop table TableA, you could delete all registers (delete from TableA;) and then populate original table with registers coming from TableA_Verify (insert into TAbleA select * from TAbleA_Verify). In this way you won't lost all references to original table (indexes,... )

CREATE TABLE TableA_Verify AS SELECT DISTINCT * FROM TableA;

DELETE FROM TableA;

INSERT INTO TableA SELECT * FROM TAbleA_Verify;

DROP TABLE TableA_Verify;

The Bootstrap datepicker is able to set date-range. But it is not available in the initial release/Master Branch. Check the branch as 'range' there (or just see at https://github.com/eternicode/bootstrap-datepicker), you can do it simply with startDate and endDate.

Example:

$('#datepicker').datepicker({
    startDate: '-2m',
    endDate: '+2d'
});

I also faced this same issue while working in my development environment, the problem was that I left host: localhost commented out in the config/database.yml file.

So my application could not connect to the PostgreSQL database, simply uncommenting it solved the issue.

development:
  <<: *default
  database: database_name

  username: database_username 

  password: database_password

  host: localhost

That's all.

I hope this helps

you can try Expiring Map http://www.java2s.com/Code/Java/Collections-Data-Structure/ExpiringMap.htm a class from The Apache MINA Project

Some options:

1. You can use the Execute Package Utility to change your datasource, before running the package.

2. You can run your package using DTEXEC, and change your connection by passing in a /CONNECTION parameter. Probably save it as a batch so next time you don't need to type the whole thing and just change the datasource as required.

3. You can use the SSIS XML package configuration file. Here is a walk through.

4. You can save your configrations in a database table.

Swift 3

let point = CGPoint(x: 0, y: 200) // 200 or any value you like.
scrollView.contentOffset = point

See this answer on SO.

There is another solution that you can use to suppress the formatting of specific block comments. Use /*- (note the hyphen) at the beginning of the block comment, and the formatting won't be affected if you format the rest of the file.

/*-
 * Here is a block comment with some very special
 * formatting that I want indent(1) to ignore.
 *
 *    one
 *        two
 *            three

Allowed default size of URI is 8177 characters in GET request. Simple code in python for such testing.

#!/usr/bin/env python2

import sys
import socket

if __name__ == "__main__":
    string = sys.argv[1]
    buf_get = "x" * int(string)
    buf_size = 1024
    request = "HEAD %s HTTP/1.1\nHost:localhost\n\n" % buf_get
    print "===>", request

    sock_http = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock_http.connect(("localhost", 80))
    sock_http.send(request)
    while True:
       print "==>", sock_http.recv(buf_size)
       if not sock_http.recv(buf_size):
           break
    sock_http.close()

On 8178 characters you will get such message: HTTP/1.1 414 Request-URI Too Large

The \#include files of gcc are stored in /usr/include . The standard include files of g++ are stored in /usr/include/c++.

You can also set the property programmatically during startup:

final String key = "java.protocol.handler.pkgs";
String newValue = "org.my.protocols";
if (System.getProperty(key) != null) {
    final String previousValue = System.getProperty(key);
    newValue += "|" + previousValue;
}
System.setProperty(key, newValue);

Using this class:

package org.my.protocols.classpath;

import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLStreamHandler;

public class Handler extends URLStreamHandler {

    @Override
    protected URLConnection openConnection(final URL u) throws IOException {
        final URL resourceUrl = ClassLoader.getSystemClassLoader().getResource(u.getPath());
        return resourceUrl.openConnection();
    }
}

Thus you get the least intrusive way to do this. :) java.net.URL will always use the current value from the system properties.

Try Wireshark or WebScarab second is better for interpolating data into the exchange (not sure Wireshark even can). Anyway, one of them should be able to help you out.

I tried Fiddler with its reverse proxy ability which is mentioned by @marxidad and it seems to be working fine, since Fiddler is a familiar UI for me and has the ability to show request/responses in various formats (i.e. Raw, XML, Hex), I accept it as an answer to this question. One thing though. I use WCF and I got the following exception with reverse proxy thing:

As ping works, but telnetto port 80 does not, the HTTP port 80 is closed on your machine. I assume that your browser's HTTP connection goes through a proxy (as browsing works, how else would you read stackoverflow?). You need to add some code to your python program, that handles the proxy, like described here:

Could you give some indication of what platforms you are writing for? This should weigh heavily on what is 'best'. You might find a super 'xml-foo' library that does not ship commonly on most systems by default .. while its great, the lack of the library might prevent (or at least) annoy users.

Mostly, I use libxml2 .. because its standard or easy to install on the platforms that I target.

As you see, 'best' is also determined by the library being available on your target platforms.

laravel 8 updated RouteServiceProvider and it affects route with string syntax, You can change it like above, but recommended way is using action syntax not using route with string syntax:

Route::get('register', 'Api\RegisterController@register');

Should be changed to:

Route::get('register', [RegisterController::class, 'register']);

Not sure you resolved this issue or not, but this is how I do it and it works on Android:

1. Use openssl to merge client's cert(cert must be signed by a CA that accepted by server) and private key into a PCKS12 format key pair: openssl pkcs12 -export -in clientcert.pem -inkey clientkey.pem -out client.p12
2. You may need patch your JRE to umlimited strength encryption depends on your key strength: copy the jar files fromJCE 5.0 unlimited strength Jurisdiction Policy FIles and override those in your JRE (eg.C:\Program Files\Java\jre6\lib\security)
3. Use Portecle tool mentioned above and create a new keystore with BKS format
4. Import PCKS12 key pair generated in step 1 and save it as BKS keystore. This keystore works with Android client authentication.
5. If you need to do certificate chain, you can use this IBM tool:KeyMan to merge client's PCKS12 key pair with CA cert. But it only generate JKS keystore, so you again need Protecle to convert it to BKS format.

Put your image in a container div then use the following CSS (changing the dimensions to suit your image.

.imageContainer{
        position: absolute;
        width: 100px; /*the image width*/
        height: 100px; /*the image height*/
        left: 50%;
        top: 50%;
        margin-left: -50px; /*half the image width*/
        margin-top: -50px; /*half the image height*/
    }

You can try this code:

public void itemClicked(View v) {
 //code to check if this checkbox is checked!
 if(((Checkbox)v).isChecked()){
   // code inside if

}

Just note to use the last_working_commit_id, when reverting a non-working commit

git reset --hard <last_working_commit_id>

So we must not reset to the commit_id that we don't want.

Then sure, we must push to remote branch:

git push --force

The ~/Library/Developer/Xcode/iOS DeviceSupport folder is basically only needed to symbolicate crash logs.

You could completely purge the entire folder. Of course the next time you connect one of your devices, Xcode would redownload the symbol data from the device.

I clean out that folder once a year or so by deleting folders for versions of iOS I no longer support or expect to ever have to symbolicate a crash log for.

You want java.text.DecimalFormat

you can pass multiple params in url like

http://localhost:2000/custom?brand=dell&limit=20&price=20000&sort=asc

and in order to get this query fields , you can use map like

    @RequestMapping(method = RequestMethod.GET, value = "/custom")
    public String controllerMethod(@RequestParam Map<String, String> customQuery) {

        System.out.println("customQuery = brand " + customQuery.containsKey("brand"));
        System.out.println("customQuery = limit " + customQuery.containsKey("limit"));
        System.out.println("customQuery = price " + customQuery.containsKey("price"));
        System.out.println("customQuery = other " + customQuery.containsKey("other"));
        System.out.println("customQuery = sort " + customQuery.containsKey("sort"));

        return customQuery.toString();

There could be a mistake in @JARH's answer in the case of a multivariable regression. (I do not have enough reputation to comment.)

In the following line:

p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-1))) for i in ts_b],

the t-values follows a chi-squared distribution of degree len(newX)-1 instead of following a chi-squared distribution of degree len(newX)-len(newX.columns)-1.

So this should be:

p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-len(newX.columns)-1))) for i in ts_b]

(See t-values for OLS regression for more details)

Use alter table to add column, for example:

alter table tableName add(columnName NUMBER);

Then create a sequence:

CREATE SEQUENCE SEQ_ID
START WITH 1
INCREMENT BY 1
MAXVALUE 99999999
MINVALUE 1
NOCYCLE;

and, the use update to insert values in column like this

UPDATE tableName SET columnName = seq_test_id.NEXTVAL

Just in case anyone are using FragmentStatePagerAdapter based adapter(which will let ViewPager create minimum pages needed for display purpose, at most 2 for my case), @rui.araujo's answer of overwriting getItemPosition in your adapter will not cause significant waste, but it still can be improved.

public int getItemPosition(Object object) {
    YourFragment f = (YourFragment) object;
    YourData d = f.data;
    logger.info("validate item position on page index: " + d.pageNo);

    int dataObjIdx = this.dataPages.indexOf(d);

    if (dataObjIdx < 0 || dataObjIdx != d.pageNo) {
        logger.info("data changed, discard this fragment.");
        return POSITION_NONE;
    }

    return POSITION_UNCHANGED;
}

To understand this peculiar behavior of hibernate, it is important to understand a few hibernate concepts -

Hibernate Object States

Transient - An object is in transient status if it has been instantiated and is still not associated with a Hibernate session.

Persistent - A persistent instance has a representation in the database and an identifier value. It might just have been saved or loaded, however, it is by definition in the scope of a Session.

Detached - A detached instance is an object that has been persistent, but its Session has been closed.

http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/objectstate.html#objectstate-overview

Transaction Write-Behind

The next thing to understand is 'Transaction Write behind'. When objects attached to a hibernate session are modified they are not immediately propagated to the database. Hibernate does this for at least two different reasons.

• To perform batch inserts and updates.
• To propagate only the last change. If an object is updated more than once, it still fires only one update statement.

http://learningviacode.blogspot.com/2012/02/write-behind-technique-in-hibernate.html

First Level Cache

Hibernate has something called 'First Level Cache'. Whenever you pass an object to save(), update() or saveOrUpdate(), and whenever you retrieve an object using load(), get(), list(), iterate() or scroll(), that object is added to the internal cache of the Session. This is where it tracks changes to various objects.

Hibernate Intercepters and Object Lifecycle Listeners -

The Interceptor interface and listener callbacks from the session to the application, allow the application to inspect and/or manipulate properties of a persistent object before it is saved, updated, deleted or loaded. http://docs.jboss.org/hibernate/orm/4.0/hem/en-US/html/listeners.html#d0e3069

This section Updated

Cascading

Hibernate allows applications to define cascade relationships between associations. For example, 'cascade-delete' from parent to child association will result in deletion of all children when a parent is deleted.

So, why are these important.

To be able to do transaction write-behind, to be able to track multiple changes to objects (object graphs) and to be able to execute lifecycle callbacks hibernate needs to know whether the object is transient/detached and it needs to have the object in it's first level cache before it makes any changes to the underlying object and associated relationships.

That's why hibernate (sometimes) issues a 'SELECT' statement to load the object (if it's not already loaded) in to it's first level cache before it makes changes to it.

Why does hibernate issue the 'SELECT' statement only sometimes?

Hibernate issues a 'SELECT' statement to determine what state the object is in. If the select statement returns an object, the object is in detached state and if it does not return an object, the object is in transient state.

Coming to your scenario -

Delete - The 'Delete' issued a SELECT statement because hibernate needs to know if the object exists in the database or not. If the object exists in the database, hibernate considers it as detached and then re-attches it to the session and processes delete lifecycle.

Update - Since you are explicitly calling 'Update' instead of 'SaveOrUpdate', hibernate blindly assumes that the object is in detached state, re-attaches the given object to the session first level cache and processes the update lifecycle. If it turns out that the object does not exist in the database contrary to hibernate's assumption, an exception is thrown when session flushes.

SaveOrUpdate - If you call 'SaveOrUpdate', hibernate has to determine the state of the object, so it uses a SELECT statement to determine if the object is in Transient/Detached state. If the object is in transient state, it processes the 'insert' lifecycle and if the object is in detached state, it processes the 'Update' lifecycle.

$ sbt sbtVersion

This prints the sbt version used in your current project, or if it is a multi-module project for each module.

$ sbt 'inspect sbtVersion'
[info] Set current project to jacek (in build file:/Users/jacek/)
[info] Setting: java.lang.String = 0.13.1
[info] Description:
[info]  Provides the version of sbt.  This setting should be not be modified.
[info] Provided by:
[info]  */*:sbtVersion
[info] Defined at:
[info]  (sbt.Defaults) Defaults.scala:68
[info] Delegates:
[info]  *:sbtVersion
[info]  {.}/*:sbtVersion
[info]  */*:sbtVersion
[info] Related:
[info]  */*:sbtVersion

You may also want to use sbt about that (copying Mark Harrah's comment):

The about command was added recently to try to succinctly print the most relevant information, including the sbt version.

The Log class:

API for sending log output.

Generally, use the Log.v() Log.d() Log.i() Log.w() and Log.e() methods.

The order in terms of verbosity, from least to most is ERROR, WARN, INFO, DEBUG, VERBOSE. Verbose should never be compiled into an application except during development. Debug logs are compiled in but stripped at runtime. Error, warning and info logs are always kept.

Outside of Android, System.out.println(String msg) is used.

I came across the same issue while trying to create a cardview programmatically, what is strange is that looking at the doc https://developer.android.com/reference/android/support/v7/widget/CardView.html#setCardBackgroundColor%28int%29, Google guys made public the api to change the background color of a card view but weirdly i didn't succeed to have access to it in the support library, so here is what worked for me:

CardViewBuilder.java

    mBaseLayout = new FrameLayout(context);
    // FrameLayout Params
    FrameLayout.LayoutParams baseLayoutParams = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);
    mBaseLayout.setLayoutParams(baseLayoutParams);

    // Create the card view.
    mCardview = new CardView(context);
    mCardview.setCardElevation(4f);
    mCardview.setRadius(8f);
    mCardview.setPreventCornerOverlap(true); // The default value for that attribute is by default TRUE, but i reset it to true to make it clear for you guys
    CardView.LayoutParams cardLayoutParams = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);
    cardLayoutParams.setMargins(12, 0, 12, 0);
    mCardview.setLayoutParams(cardLayoutParams);
    // Add the card view to the BaseLayout
    mBaseLayout.addView(mCardview);

    // Create a child view for the cardView that match it's parent size both vertically and horizontally
    // Here i create a horizontal linearlayout, you can instantiate the view of your choice
    mFilterContainer = new LinearLayout(context);
    mFilterContainer.setOrientation(LinearLayout.HORIZONTAL);
    mFilterContainer.setPadding(8, 8, 8, 8);
    mFilterContainer.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,

    // And here is the magic to get everything working
    // I create a background drawable for this view that have the required background color
    // and match the rounded radius of the cardview to have it fit in.
    mFilterContainer.setBackgroundResource(R.drawable.filter_container_background);

    // Add the horizontal linearlayout to the cardview.
    mCardview.addView(mFilterContainer);

filter_container_background.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<corners android:radius="8dp"/>
<solid android:color="@android:color/white"/>

Doing that i succeed in keeping the cardview shadow and rounded corners.

There are predefined macros that are used by most compilers, you can find the list here. GCC compiler predefined macros can be found here. Here is an example for gcc:

#if defined(WIN32) || defined(_WIN32) || defined(__WIN32__) || defined(__NT__)
   //define something for Windows (32-bit and 64-bit, this part is common)
   #ifdef _WIN64
      //define something for Windows (64-bit only)
   #else
      //define something for Windows (32-bit only)
   #endif
#elif __APPLE__
    #include <TargetConditionals.h>
    #if TARGET_IPHONE_SIMULATOR
         // iOS Simulator
    #elif TARGET_OS_IPHONE
        // iOS device
    #elif TARGET_OS_MAC
        // Other kinds of Mac OS
    #else
    #   error "Unknown Apple platform"
    #endif
#elif __linux__
    // linux
#elif __unix__ // all unices not caught above
    // Unix
#elif defined(_POSIX_VERSION)
    // POSIX
#else
#   error "Unknown compiler"
#endif

The defined macros depend on the compiler that you are going to use.

The _WIN64 #ifdef can be nested into the _WIN32 #ifdef because _WIN32 is even defined when targeting the Windows x64 version. This prevents code duplication if some header includes are common to both (also WIN32 without underscore allows IDE to highlight the right partition of code).

If it's raising a KeyError with no message, then it won't print anything. If you do...

try:
    connection = manager.connect("I2Cx")
except Exception as e:
    print repr(e)

...you'll at least get the exception class name.

A better alternative is to use multiple except blocks, and only 'catch' the exceptions you intend to handle...

try:
    connection = manager.connect("I2Cx")
except KeyError as e:
    print 'I got a KeyError - reason "%s"' % str(e)
except IndexError as e:
    print 'I got an IndexError - reason "%s"' % str(e)

There are valid reasons to catch all exceptions, but you should almost always re-raise them if you do...

try:
    connection = manager.connect("I2Cx")
except KeyError as e:
    print 'I got a KeyError - reason "%s"' % str(e)
except:
    print 'I got another exception, but I should re-raise'
    raise

...because you probably don't want to handle KeyboardInterrupt if the user presses CTRL-C, nor SystemExit if the try-block calls sys.exit().

This problem appears when you have a path or a property containing a space and that is not quoted.

If I understand the question, you want to change the value of the checkbox depending if it is checked or not.

Here is one solution:

$('#checkbox-value').text($('#checkbox1').val());_x000D_
_x000D_
$("#checkbox1").on('change', function() {_x000D_
  if ($(this).is(':checked')) {_x000D_
    $(this).attr('value', 'true');_x000D_
  } else {_x000D_
    $(this).attr('value', 'false');_x000D_
  }_x000D_
  _x000D_
  $('#checkbox-value').text($('#checkbox1').val());_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
<input type="checkbox" name="acceptRules" class="inline checkbox" id="checkbox1" value="false">_x000D_
_x000D_
<div id="checkbox-value"></div>

Downloading Wget is not necessary; the .NET Framework has web client classes built in.

$wc = New-Object system.Net.WebClient;
$sms = Read-Host "Enter SMS text";
$sms = [System.Web.HttpUtility]::UrlEncode($sms);
$smsResult = $wc.downloadString("http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$sms&encoding=windows-1255")

Another gotcha here wasted some of my time, so I thought I would pass along the tip. I had a hidden field I gave an id that had . and [] brackets in the name (due to use with struts2) and the selector $("#model.thefield[0]") would not find my hidden field. Renaming the id to not use the periods and brackets caused the selector to begin working. So in the end I ended up with an id of model_the_field_0 instead and the selector worked fine.

std::move itself doesn't really do much. I thought that it called the moved constructor for an object, but it really just performs a type cast (casting an lvalue variable to an rvalue so that the said variable can be passed as an argument to a move constructor or assignment operator).

So std::move is just used as a precursor to using move semantics. Move semantics is essentially an efficient way for dealing with temporary objects.

Consider Object A = B + C + D + E + F;

This is nice looking code, but E + F produces a temporary object. Then D + temp produces another temporary object and so on. In each normal "+" operator of a class, deep copies occur.

For example

Object Object::operator+ (const Object& rhs) {
    Object temp (*this);
    // logic for adding
    return temp;
}

The creation of the temporary object in this function is useless - these temporary objects will be deleted at the end of the line anyway as they go out of scope.

We can rather use move semantics to "plunder" the temporary objects and do something like

 Object& Object::operator+ (Object&& rhs) {
     // logic to modify rhs directly
     return rhs;
 }

This avoids needless deep copies being made. With reference to the example, the only part where deep copying occurs is now E + F. The rest uses move semantics. The move constructor or assignment operator also needs to be implemented to assign the result to A.

For people who use Android Studio the problem may be solved by editing versionCode and versionName in build.gradle instead of AndroidManifest.xml.

e.g.

defaultConfig {
    applicationId "com.my.packageId"
    minSdkVersion 15
    targetSdkVersion 22
    versionCode 2      <-- change this
    versionName "2.0"  <-- change this
}

The most elegant way to fix this: use pipe. Here is example (my blog). So you can then simply use url | safe pipe to bypass the security.

There are few steps to be followed (For Windows)

1. Open Git Bash and generate ssh key Paste the text below, substituting in your GitHub email address.

   ssh-keygen -t rsa -b 4096 -C "[email protected]"

   This creates a new ssh key, using the provided email as a label.

   Generating public/private rsa key pair.

   When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.

   Enter a file in which to save the key (/c/Users/you/.ssh/id_rsa):[Press enter]

   At the prompt, type a secure passphrase. For more information, see "Working with SSH key passphrases".

   Enter passphrase (empty for no passphrase): [Type a passphrase] Enter same passphrase again: [Type passphrase again]

2. Add the key to SSH Agent

   Type the following in Git Bash (99999 is just an example) to see agent is up and running. eval $(ssh-agent -s) Agent pid 99999

   then type this.

   ssh-add ~/.ssh/id_rsa

   then Copy the SSH key to your clipboard using this command

   clip < ~/.ssh/id_rsa.pub

3. Add the SSH Key to the Git Account

   In GitHib site, click on the image on top right corner, and select settings. In the subsequent page, click SSH and GPG keys option. This will open up the SSH key page. Click on the New SSH key. In the "Title" field, add a descriptive label for the new key. Paste your key into the "Key" field.

4. Clone the Repository

   Open VS Code (or any IDE/CLI which has command prompt etc.). Go to the directory in which you want to clone, using cd commands, and type the below line. git config --global github.user yourGitUserName git config --global user.email your_email git clone [email protected]:yourGitUserName/YourRepoName.git

https://help.github.com/articles/adding-a-new-ssh-key-to-your-github-account/

The * character is not allowed in the path of the URL, but there is no problem using it in the query string:

http://localhost:3286/Search/?q=test*

It's not an encoding issue, the * character has no special meaning in an URL, so it doesn't matter if you URL encode it or not. You would need to encode it using a different scheme, and then decode it.

For example using an arbitrary character as escape character:

query = query.Replace("x", "xxx").Replace("y", "xxy").Replace("*", "xyy");

And decoding:

query = query.Replace("xyy", "*").Replace("xxy", "y").Replace("xxx", "x");

As a script, or replace $@ with your files.

#!/usr/bin/env bash

Try this JS solution that toggles webkitOverflowScrolling style. The trick here is that this style is off, mobile Safari goes to ordinary scrolling and prevents over-bounce — alas, it is not able to cancel ongoing drag. This complex solution also tracks onscroll as bounce over the top makes scrollTop negative that may be tracked. This solution was tested on iOS 12.1.1 and has single drawback: while accelerating the scroll single over-bounce still happens as resetting the style may not cancel it immediately.

function preventScrollVerticalBounceEffect(container) {
  setTouchScroll(true) //!: enable before the first scroll attempt

  container.addEventListener("touchstart", onTouchStart)
  container.addEventListener("touchmove", onTouch, { passive: false })
  container.addEventListener("touchend", onTouchEnd)
  container.addEventListener("scroll", onScroll)

  function isTouchScroll() {
    return !!container.style.webkitOverflowScrolling
  }

  let prevScrollTop = 0, prevTouchY, opid = 0

  function setTouchScroll(on) {
    container.style.webkitOverflowScrolling = on ? "touch" : null

    //Hint: auto-enabling after a small pause makes the start
    // smoothly accelerated as required. After the pause the
    // scroll position is settled, and there is no delta to
    // make over-bounce by dragging the finger. But still,
    // accelerated content makes short single over-bounce
    // as acceleration may not be off instantly.

    const xopid = ++opid
    !on && setTimeout(() => (xopid === opid) && setTouchScroll(true), 250)

    if(!on && container.scrollTop < 16)
      container.scrollTop = 0
    prevScrollTop = container.scrollTop
  }

  function isBounceOverTop() {
    const dY = container.scrollTop - prevScrollTop
    return dY < 0 && container.scrollTop < 16
  }

  function isBounceOverBottom(touchY) {
    const dY = touchY - prevTouchY

    //Hint: trying to bounce over the bottom, the finger moves
    // up the screen, thus Y becomes smaller. We prevent this.

    return dY < 0 && container.scrollHeight - 16 <=
      container.scrollTop + container.offsetHeight
  }

  function onTouchStart(e) {
    prevTouchY = e.touches[0].pageY
  }

  function onTouch(e) {
    const touchY = e.touches[0].pageY

    if(isBounceOverBottom(touchY)) {
      if(isTouchScroll())
        setTouchScroll(false)
      e.preventDefault()
    }

    prevTouchY = touchY
  }

  function onTouchEnd() {
    prevTouchY = undefined
  }

  function onScroll() {
    if(isTouchScroll() && isBounceOverTop()) {
      setTouchScroll(false)
    }
  }
}

Updated for npm v2+

npm 2+ (Node 0.12+):

npm outdated
npm update
git commit package-lock.json

Ancient npm (circa 2014):

npm install -g npm-check-updates
npm-check-updates
npm shrinkwrap
git commit package-lock.json

Be sure to shrinkwrap your deps, or you may wind up with a dead project. I pulled out a project the other day and it wouldn't run because my deps were all out of date/updated/a mess. If I'd shrinkwrapped, npm would have installed exactly what I needed.

Details

For the curious who make it this far, here is what I recommend:

Use npm-check-updates or npm outdated to suggest the latest versions.

# `outdated` is part of newer npm versions (2+)
$ npm outdated
# If you agree, update.  
$ npm update

#       OR

# Install and use the `npm-check-updates` package.
$ npm install -g npm-check-updates
# Then check your project
$ npm-check-updates
# If you agree, update package.json.
$ npm-check-updates -u

###Then do a clean install (w/o the rm I got some dependency warnings)

$ rm -rf node_modules
$ npm install 

Lastly, save exact versions to npm-shrinkwrap.json with npm shrinkwrap

$ rm npm-shrinkwrap.json
$ npm shrinkwrap

Now, npm install will now use exact versions in npm-shrinkwrap.json

If you check npm-shrinkwrap.json into git, all installs will use the exact same versions.

This is a way to transition out of development (all updates, all the time) to production (nobody touch nothing).

• npm outdated

• npm-check-updates

• npm shrinkwrap

Yet another approach is ISNULL().

UPDATE [DATABASE].[dbo].[TABLE_NAME]
SET    
    [ABC]  = ISNULL(@ABC, [ABC]),
    [ABCD] = ISNULL(@ABCD, [ABCD])

The difference between ISNULL and COALESCE is the return type. COALESCE can also take more than 2 arguments, and use the first that is not null. I.e.

select COALESCE(null, null, 1, 'two') --returns 1
select COALESCE(null, null, null, 'two') --returns 'two'

In short I would say no, the juice is not worth the squeeze to test a service method with a single line that retrieves model data. In my experience people who are new to TDD want to test absolutely everything. The old chestnut of abstracting a facade to a 3rd party framework just so you can create a mock of that frameworks API with which you bastardise/extend so that you can inject dummy data is of little value in my mind. Everyone has a different view of how much unit testing is best. I tend to be more pragmatic these days and ask myself if my test is really adding value to the end product, and at what cost.

To save others a few seconds, and to save them from having to read the manual, here's the short answer. Add this to the top of your make file:

.DEFAULT_GOAL := mytarget

mytarget will now be the target that is run if "make" is executed and no target is specified.

If you have an older version of make (<= 3.80), this won't work. If this is the case, then you can do what anon mentions, simply add this to the top of your make file:

.PHONY: default
default: mytarget ;

References: https://www.gnu.org/software/make/manual/html_node/How-Make-Works.html

Console.WriteLine(decimal.Round(pay,2));

For passive mode you need to use command "literal" ftp>literal PASV

If getFiles() returns a java.util.Collection, !getFiles().isEmpty() && size<5 can be OK.

On the other hand, unless you encapsulate the container which provides method such as boolean sizeBetween(int min, int max).

Make sure that you do not have any null or NaN values in the list you want to sort. If there are NaN values, then your sort will be off, impacting the sorting of the non-null values.

Check out Python: sort function breaks in the presence of nan

Another solution is to check for the command's exit code.

git rev-parse 2> /dev/null; [ $? == 0 ] && echo 1

This will print 1 if you're in a git repository folder.

It sucks but you can get the bean by using the ApplicationContextAware interface. Something like :

public class Boo implements ApplicationContextAware {

    private static ApplicationContext appContext;

    @Autowired
    Foo foo;

    public static void randomMethod() {
         Foo fooInstance = appContext.getBean(Foo.class);
         fooInstance.doStuff();
    }

    @Override
    public void setApplicationContext(ApplicationContext appContext) {
        Boo.appContext = appContext;
    }
}

Well if you are using Netbeans in Linux, then you should look for the tomcat-user.xml in

/home/Username/.netbeans/8.0/apache-tomcat-8.0.3.0_base/conf (its called Catalina Base and is often hidden)

instead of the apacahe installation directory.

open tomcat-user.xml inside that folder, uncomment the user and roles and add/replace the following line.

    <user username="tomcat" password="tomcat" roles="tomcat,admin,admin-gui,manager,manager-gui"/>

restart the server . That's all

As of Laravel 5.2+, you can fetch it directly with $request->input('item') as well.

Retrieving JSON Input Values

When sending JSON requests to your application, you may access the JSON data via the input method as long as the Content-Type header of the request is properly set to application/json. You may even use "dot" syntax to dig deeper into JSON arrays:

$name = $request->input('user.name');

https://laravel.com/docs/5.2/requests

As noted above, the content-type header must be set to application/json so the jQuery ajax call would need to include contentType: "application/json",

$.ajax({
    type: "POST",
    url: "/people",
    data: '[{ "name": "John", "location": "Boston" }, { "name": "Dave", "location": "Lancaster" }]',
    dataType: "json",
    contentType: "application/json",
    success:function(data) {
        $('#save_message').html(data.message);
    } 
});

By fixing the AJAX call, $request->all() should work.

Since everything was working fine for weeks then stopped, I doubt this has anything to do with your code. Perhaps the error is occurring when the service is activated within IIS/ASP.NET, not when your code is called. The runtime could just be checking the configuration of the web site and throwing a generic error message which has nothing to do with the service.

My suspicion is that a certificate has expired or that the bindings are set up incorrectly. If the web site is mis-configured for HTTPS, whether your code uses them or not, you may be getting this error.

<strong> and <em> - unlike <b> and <i> - have clear purpose for web browsers for the blind.

A blind person doesn't browse the web visually, but by sound such as text readers. <strong> and <em>, in addition to encouraging something to be bold or italic, also convey loudness or stressing syllables respectively (OH MY! & Ooooooh Myyyyyyy!). Audio-only browsers are unpredictable when it comes to <b> and <i>... they may make them loud or stress them or they may not... you never can be sure unless you use <strong> and <em>.

Swift uses the same runtime as Objective-C and can even live side-by-side Objective-C in the same application (as per the WWDC 2014 keynote).

This will need to be checked/verified using Xcode 6 and the new SDK to find a final answer.

If statements embedded in SQL queries is a bad "code smell". Bad code has high "WTF's per minute" during code review. This is one of those things. If I see this in production with your name on it, I'm going to automatically not like you.

An additional option is to go to your build folder and use the command ccmake .

This is like the GUI but terminal based. This obviously won't help with an installation script but at least it can be run without a UI.

The one warning I have is it won't let you generate sometimes when you have warnings. if that is the case, exit the interface and call cmake .

Use the size property on the UIImage instance. See the documentation for more details.

Use scale instead! After many researches and tests I have made this plugin to achieve it cross browser:

$.fn.scale = function(x) {
    if(!$(this).filter(':visible').length && x!=1)return $(this);
    if(!$(this).parent().hasClass('scaleContainer')){
        $(this).wrap($('<div class="scaleContainer">').css('position','relative'));
        $(this).data({
            'originalWidth':$(this).width(),
            'originalHeight':$(this).height()});
    }
    $(this).css({
        'transform': 'scale('+x+')',
        '-ms-transform': 'scale('+x+')',
        '-moz-transform': 'scale('+x+')',
        '-webkit-transform': 'scale('+x+')',
        'transform-origin': 'right bottom',

        'position': 'absolute',
        'bottom': '0',
        'right': '0',
    });
    if(x==1)
        $(this).unwrap().css('position','static');else
            $(this).parent()
                .width($(this).data('originalWidth')*x)
                .height($(this).data('originalHeight')*x);
    return $(this);

$(selector).scale(0.5);

note:

It will create a wrapper with a class scaleContainer. Take care of that while styling content.

EDIT (April 2014): This is a question/answer page that still gets a lot of hits it seems. I know I'm always getting upvotes for this post. But if you're reading this, you need to realize the answers posted here (both mine and the accepted answer) are out of date. If you want to implement efficient blur today, you should use RenderScript instead of the NDK or Java. RenderScript runs on Android 2.2+ (using the Android Support Library), so there's no reason not to use it.

The old answer follows, but beware as it's outdated.

For future² Googlers, here is an algorithm that I ported from Yahel's port of Quasimondo's algorithm, but using the NDK. It's based on Yahel's answer, of course. But this is running native C code, so it's faster. Much faster. Like, 40 times faster.

I find that using the NDK is how all image manipulation should be done on Android... it's somewhat annoying to implement at first (read a great tutorial on using JNI and the NDK here), but much better, and near real time for a lot of things.

For reference, using Yahel's Java function, it took 10 seconds to blur my 480x532 pixels image with a blur radius of 10. But it took 250ms using the native C version. And I'm pretty sure it can still be further optimized... I just did a dumb conversion of the java code, there's probably some manipulations that can be shortened, didn't want to spend too much time refactoring the whole thing.

}

int min(int a, int b) {
    return a > b ? b : a;
}

int max(int a, int b) {
    return a > b ? a : b;
}

Then use it like this (considering a class called com.insert.your.package.ClassName and a native function called functionToBlur, as the code above states):

// Create a copy
Bitmap bitmapOut = bitmapIn.copy(Bitmap.Config.ARGB_8888, true);
// Blur the copy
functionToBlur(bitmapIn, bitmapOut, __radius);

It expects a RGB_8888 bitmap!

To use a RGB_565 bitmap, either create a converted copy before passing the parameter (yuck), or change the function to use a new rgb565 type instead of rgba:

typedef struct {
    uint16_t byte0;
} rgb565;

The problem is that if you do that you can't read .red, .green and .blue of the pixel anymore, you need to read the byte properly, duh. When I needed that before, I did this:

r = (pixels[x].byte0 & 0xF800) >> 8;
g = (pixels[x].byte0 & 0x07E0) >> 3;
b = (pixels[x].byte0 & 0x001F) << 3;

But there's probably some less dumb way of doing it. I'm not much of a low-level C coder, I'm afraid.

Managed to get the input field value by doing something like this:

import React, { Component } from 'react';

class App extends Component {

constructor(props){
super(props);

this.state = {
  username : ''
}

this.updateInput = this.updateInput.bind(this);
this.handleSubmit = this.handleSubmit.bind(this);
}


updateInput(event){
this.setState({username : event.target.value})
}


handleSubmit(){
console.log('Your input value is: ' + this.state.username)
//Send state to the server code
}



render(){
return (
    <div>
    <input type="text" onChange={this.updateInput}></input>
    <input type="submit" onClick={this.handleSubmit} ></input>
    </div>
  );
}
} 

//output
//Your input value is: x

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

You can use the strtotime and date functions like this:

echo date('Y', strtotime('2068-06-15'));

Note however that PHP can handle year upto 2038

You can test it out here

If your date is always in that format, you can also get the year like this:

$parts = explode('-', '2068-06-15');
echo $parts[0];

That's not a typical Wordpress rewrite block. This is:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

See http://codex.wordpress.org/Using_Permalinks#Where.27s_my_.htaccess_file.3F

Where's my .htaccess file? WordPress's index.php and .htaccess files should be together in the directory indicated by the Site address (URL) setting on your General Options page. Since the name of the file begins with a dot, the file may not be visible through an FTP client unless you change the preferences of the FTP tool to show all files, including the hidden files. Some hosts (e.g. Godaddy) may not show or allow you to edit .htaccess if you install WordPress through the Godaddy Hosting Connection installation.

Creating and editing (.htaccess) If you do not already have a .htaccess file, create one. If you have shell or ssh access to the server, a simple touch .htaccess command will create the file. If you are using FTP to transfer files, create a file on your local computer, call it 1.htaccess, upload it to the root of your WordPress folder, and then rename it to .htaccess.

You can edit the .htaccess file by FTP, shell, or (possibly) your host's control panel.

The easiest and fastest thing to do it reset your permalinks in Dashboard>>Settings>>Permalinks and make sure .htaccess is writable so WordPress can write the rules itself.

And: are you aware you are calling index.cgi as your default document rather than index.php? That's wrong. Remove index.cgi. Or try removing the whole line, too, because defining a default doc on your server may not be needed.

It's a pandas data-frame and it's using label base selection tool with df.loc and in it, there are two inputs, one for the row and the other one for the column, so in the row input it's selecting all those row values where the value saved in the column class is versicolor, and in the column input it's selecting the column with label class, and assigning Iris-versicolor value to them. So basically it's replacing all the cells of column class with value versicolor with Iris-versicolor.

Also worth noting, for people who find this in their searches, is this...

<div ng-repeat="button in buttons" class="bb-button" ng-click="goTo(button.path)">
  <div class="bb-button-label">{{ button.label }}</div>
  <div class="bb-button-description">{{ button.description }}</div>
</div>

Note the value of ng-click. The parameter passed to goTo() is a string from a property of the binding object (the button), but it is not wrapped in quotes. Looks like AngularJS handles that for us. I got hung up on that for a few minutes.

Giving travel directions: With each step in the directions being a node, and the travel instruction between each node as your link.

Example:

Node 1: Start at Home

Link: Walk 3 blocks South to Bob's House

Node 2: Bob's house

Link: Walk 2 blocks North to Alice's House.

Node 3: Alice's house

If you want to get one place to another you have to follow the links(instructions) from each intermediate place(node), you can't just skip from home to Alice's.

Another way to do this, if you have already initialised a form (with or without data), and you need to add further data before displaying it:

form = Form(request.POST.form)
form.data['Email'] = GetEmailString()

I had a similar problem and it turned out the issue was having both versions 6 & 7 of OpenJDK. The answer comes from r-senior on ubuntu forums (http://ubuntuforums.org/showthread.php?t=1977619) --- just uninstall version 6:

sudo apt-get remove openjdk-6-*

make sure that JAVA_HOME and CLASSPATH aren't set to anything since that isn't actually the problem.

yes you can, look for std::reference_wrapper, that mimics a reference but is assignable and also can be "reseated"

You are not setting a classpath that includes your compiled class! java can't find any classes if you don't tell it where to look.

java -cp [compiler outpur dir] HelloWorld

Incidentally you do not need to set CLASSPATH the way you have done.

This won't help you step through code or break on errors, but it's a useful way to get the same debug console for your project on all browsers.

This is put together pretty hastily and is a bit sloppy, but it's useful nonetheless and can be improved easily!

On my side it was coming from an error in my settings.xml file. I had a bad tag. Just removed it, refreshed and i was good to go.

No, that's it. You might want to make sure you have all optional library headers installed too so you don't have to recompile it later. They are listed in the documentation I think.

Also, you can install it even in the standard path if you do make altinstall. That way it won't override your current default "python".

It says what it means:

make your class non-static:

public class employee
{
  NameValueCollection appSetting = ConfigurationManager.AppSettings;    
}

or the member static:

public static class employee
{
  static NameValueCollection appSetting = ConfigurationManager.AppSettings;    
}

You know what, there is an entire library for canvas graphics. It is called p5.js You can add it with just a single line in your head element and an additional sketch.js file.

Do this to your html and body tags first:

<html style="margin:0 ; padding:0">
<body style="margin:0 ; padding:0">

Add this to your head:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/0.6.1/p5.js"></script>
<script type="text/javascript" src="sketch.js"></script>

The sketch.js file

function setup() {
    createCanvas(windowWidth, windowHeight);
    background(r, g, b);
}

Using jQuery

$('#note textarea');

or just

$('#textid');

FYI for those that are trying to create a package installer for a bundle or plugin, it's easy:

pkgbuild --component "Color Lists.colorPicker" --install-location ~/Library/ColorPickers ColorLists.pkg

resize:none; This property fix your text area and bound it. you use this css property id your textarea.gave text area an id and on the behalf of that id you can use this css property.

Surely:

if (useAdditionalClauses) 
{ 
  results = 
    results.Where(o => o.OrderStatus == OrderStatus.Open && 
    o.CustomerID == customerID)  
} 

Or just another .Where() call like this one (although I don't know why you would want to, unless it's split by another boolean control variable):

if (useAdditionalClauses) 
{ 
  results = results.Where(o => o.OrderStatus == OrderStatus.Open).
    Where(o => o.CustomerID == customerID);
} 

Or another reassignment to results: `results = results.Where(blah).

You're asking for all the elements of class facetContainerDiv, of which there is only one (your outer-most div). Why not do

List<WebElement> checks =  driver.findElements(By.class("facetCheck"));
// click the 3rd checkbox
checks.get(2).click();

After you create image, check it with:

$ docker inspect $image_name 

and check what you have in CMD option. For busy box it should be:

"Cmd": [
     "/bin/sh"
]

Maybe you are overwritting CMD option in your ./mkimage.sh

javax.servlet is a package that's part of Java EE (Java Enterprise Edition). You've got the JDK for Java SE (Java Standard Edition).

You could use the Java EE SDK for example.

Alternatively simple servlet containers such as Apache Tomcat also come with this API (look for servlet-api.jar).

The data-reactid attribute is a custom attribute used so that React can uniquely identify its components within the DOM.

This is important because React applications can be rendered at the server as well as the client. Internally React builds up a representation of references to the DOM nodes that make up your application (simplified version is below).

There's no way to share the actual object references between the server and the client and sending a serialized version of the entire component tree is potentially expensive. When the application is rendered at the server and React is loaded at the client, the only data it has are the data-reactid attributes.

<div data-reactid='.loqi70ccu80'>
  <span data-reactid='.loqi70ccu80.0'>
    <input data-reactid='.loqi70ccu80.0' />
  </span>
</div>

It needs to be able to convert that back into the data structure above. The way it does that is with the unique data-reactid attributes. This is called inflating the component tree.

You might also notice that if React renders at the client-side, it uses the data-reactid attribute, even though it doesn't need to lose its references. In some browsers, it inserts your application into the DOM using .innerHTML then it inflates the component tree straight away, as a performance boost.

The other interesting difference is that client-side rendered React ids will have an incremental integer format (like .0.1.4.3), whereas server-rendered ones will be prefixed with a random string (such as .loqi70ccu80.1.4.3). This is because the application might be rendered across multiple servers and it's important that there are no collisions. At the client-side, there is only one rendering process, which means counters can be used to ensure unique ids.

React 15 uses document.createElement instead, so client rendered markup won't include these attributes anymore.

Most of the time you would create a list in groovy rather than an array. You could do it like this:

names = ["lucas", "Fred", "Mary"]

Alternately, if you did not want to quote everything like you did in the ruby example, you could do this:

names = "lucas Fred Mary".split()

Open your command prompt type

pip3 list

Maybe this is a bit redundant, but no one appeared to have mentioned this as a solution.

As a beginner in SQL I find that when using a BEGIN and END SSMS usually adds a squiggly line with incorrect syntax near 'END' to END, simply because there's no content in between yet. If you're just setting up BEGIN and END to get started and add the actual query later, then simply add a bogus PRINT statement so SSMS stops bothering you.

For example:

IF (1=1)
BEGIN
  PRINT 'BOGUS'
END

The following will indeed set you on the wrong track, thinking you made a syntax error which in this case just means you still need to add content in between BEGIN and END:

IF (1=1)
BEGIN
END

If you want to call functions on components from outside React, you can call them on the return value of renderComponent:

var Child = React.createClass({…});
var myChild = React.renderComponent(Child);
myChild.someMethod();

The only way to get a handle to a React Component instance outside of React is by storing the return value of React.renderComponent. Source.

In Android Studio

1) Open terminal and ensure you are at project's root folder.

2) Run ./gradlew app:dependencies (if not using gradle wrapper, try gradle app:dependencies)

Note that running ./gradle dependencies will only give you dependency tree of project's root folder, so mentioning app in above manner, i.e. ./gradlew app:dependencies is important.

This might be late as I think most of us are using BS4. This article explained all the questions you asked in a detailed and simple manner also includes what to do when. The detailed guide to use bs4 or bootstrap

Thanks peter, now i change my code.

<input type='date' id='d1' name='d1'>

<script type="text/javascript">
var d1 = new Date();
var y1= d1.getFullYear();
var m1 = d1.getMonth()+1;
if(m1<10)
    m1="0"+m1;
var dt1 = d1.getDate();
if(dt1<10)
dt1 = "0"+dt1;
var d2 = y1+"-"+m1+"-"+dt1;
document.getElementById('d1').value=d2;
</script>

you can implement a generic solution for decisions and use in another case not just for yes/no and custom the alert with animations or layout:

Something like this; first create your class for transfer datas:

public class AlertDecision {

    private String question = "";
    private String strNegative = "";
    private String strPositive = "";

    public AlertDecision question(@NonNull String question) {
        this.question = question;
        return this;
    }

    public AlertDecision ansPositive(@NonNull String strPositive) {
        this.strPositive = strPositive;
        return this;
    }

    public AlertDecision ansNegative(@NonNull String strNegative) {
        this.strNegative = strNegative;
        return this;
    }

    public String getQuestion() {
        return question;
    }

    public String getAnswerNegative() {
        return strNegative;
    }

    public String getAnswerPositive() {
        return strPositive;
    }
}

after a interface for return the result

public interface OnAlertDecisionClickListener {

    /**
     * Interface definition for a callback to be invoked when a view is clicked.
     *
     * @param dialog the dialog that was clicked
     * @param object The object in the position of the view
     */
    void onPositiveDecisionClick(DialogInterface dialog, Object object);
    void onNegativeDecisionClick(DialogInterface dialog, Object object);
}

Now you can create an utils for access easily (in this class you can implement different animation or custom layout for the alert):

public class AlertViewUtils {

    public static void showAlertDecision(Context context,
                                         @NonNull AlertDecision decision,
                                         final OnAlertDecisionClickListener listener,
                                         final Object object) {

        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setMessage(decision.getQuestion());
        builder.setPositiveButton(decision.getAnswerPositive(),
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        listener.onPositiveDecisionClick(dialog, object);
                    }
                });

        builder.setNegativeButton(decision.getAnswerNegative(),
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        listener.onNegativeDecisionClick(dialog, object);
                    }
                });

        android.support.v7.app.AlertDialog dialog = builder.create();
        dialog.show();
    }
}

and the last call in activity or fragment; you can use this in you case or for other task:

public class MainActivity extends AppCompatActivity {

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);
        initResources();
    }

    public void initResources() {
        Button doSomething = (Button) findViewById(R.id.btn);
        doSomething.setOnClickListener(getDecisionListener());
    }

    private View.OnClickListener getDecisionListener() {
        return new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                AlertDecision decision = new AlertDecision()
                        .question("question ...")
                        .ansNegative("negative action...")
                        .ansPositive("positive action... ");
                AlertViewUtils.showAlertDecision(MainActivity.this,
                        decision, getOnDecisionListener(), v);
            }
        };
    }

    private OnAlertDecisionClickListener getOnDecisionListener() {
        return new OnAlertDecisionClickListener() {
            @Override
            public void onPositiveDecisionClick(DialogInterface dialog, Object object) {

                //do something like create, show views, etc...
            }

            @Override
            public void onNegativeDecisionClick(DialogInterface dialog, Object object) {
                //do something like delete, close session, etc ...
            }
        };
    }
} 

I would like to say that you must always use jQuery latest or recent stable versions. However if you need to do some work with others versions then you can add that version and renamed the $ to some other name. For instance

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
<script>var $oldjQuery = $.noConflict(true);</script>

Look here if you write something using $ then you will get the latest version. But if you need to do anything with old then just use$oldjQuery instead of $.

Here is an example

$(function(){console.log($.fn.jquery)});
$oldjQuery (function(){console.log($oldjQuery.fn.jquery)})

Demo

I've done it using Gson (by Google).

Add the following line to your module's build.gradle:

dependencies {
  // ...
  // Note that `compile` will be deprecated. Use `implementation` instead.
  // See https://stackoverflow.com/a/44409111 for more info
  implementation 'com.google.code.gson:gson:2.8.2'
}

ContactModel.java:

public class ContactModel {
     public String id;
     public String name;
     public String email;
}

Code for converting a JSON string to ArrayList<Model>:

Note: You have to import java.lang.reflect.Type;:

// Top of file
import java.lang.reflect.Type;

// ...

private void parseJSON() {
    Gson gson = new Gson();
    Type type = new TypeToken<List<ContactModel>>(){}.getType();
    List<ContactModel> contactList = gson.fromJson(jsonString, type);
    for (ContactModel contact : contactList){
        Log.i("Contact Details", contact.id + "-" + contact.name + "-" + contact.email);
    }
}

Hope this will help you.

You can also use OPENROWSET to import excel file in sql server.

SELECT * INTO Your_Table FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0',
                        'Excel 12.0;Database=C:\temp\MySpreadsheet.xlsx',
                        'SELECT * FROM [Data$]')

My comment might not be relevant to the tags given. However, I was lead to this page from my search. I was looking for similar check in R and I came up the following with the help of @hugovdbeg post. I hope it would be helpful for someone who is looking for similar solution in R

'USERNAME' %in% names(Sys.getenv())

If you are having a problem with NULL values, use the COALESCE function to replace the NULL with the value of your choice. Your query would then look like this:

SELECT (COALESCE(field1, '') + '' + COALESCE(field2, '') + '' + COALESCE(field3,'')) FROM table1

make sure dependencies for jetty naming and jetty plus are included (not just provided scope). This fixed it for me.

I've just had a similar issue. The project had opened using Java 9 but even after all the modules and project were set back to 1.8, I was still getting the error.

I needed to force Gradle to refresh the project and then everything ran as expected.

As pointed out by Thomas Stjernegaard Jeppesen, you could use History.js to modify URL parameters whilst the user navigates through your Ajax links and apps.

Almost an year has passed since that answer, and History.js grew and became more stable and cross-browser. Now it can be used to manage history states in HTML5-compliant as well as in many HTML4-only browsers. In this demo You can see an example of how it works (as well as being able to try its functionalities and limits.

Should you need any help in how to use and implement this library, i suggest you to take a look at the source code of the demo page: you will see it's very easy to do.

Finally, for a comprehensive explanation of what can be the issues about using hashes (and hashbangs), check out this link by Benjamin Lupton.

In summary :

<input type="submit">

<button type="submit"> Submit </button>

Both by default will visually draw a button that performs the same action (submit the form).

However, it is recommended to use <button type="submit"> because it has better semantics, better ARIA support and it is easier to style.

What I did so far in my projects was was to revert the :hover changes on touch devices:

.myhoveredclass {
    background-color:green;
}
.myhoveredclass:hover {
    background-color:red;
}
@media screen and (-webkit-min-device-pixel-ratio:0) {
    .myhoveredclass:hover, .myhoveredclass:active, .myhoveredclass:focus {
        background-color:green;
    }
}

All class names and named colors just for demonstration purposes ;-)

Simply

pip show numpy

and for pip3

pip3 show numpy

Works on both windows and linux. Should work on mac too if you are using pip.

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)

In app.config file (or .exe.config) you can add or change the "receiveTimeout" property in binding. like this

<binding name="WebServiceName" receiveTimeout="00:00:59" />

Keep it simple:

1. cross-domain POST:
   use crossDomain: true,

2. shouldn't refresh the page:
   No, it will not refresh the page as the success or error async callback will be called when the server send back the response.

Example script:

$.ajax({
        type: "POST",
        url: "http://www.yoururl.com/",
        crossDomain: true,
        data: 'param1=value1&param2=value2',
        success: function (data) {
            // do something with server response data
        },
        error: function (err) {
            // handle your error logic here
        }
    });

in additional to your way
you could call system ps command and get memory usage from it output.
or read info from /proc/pid ( see PIOCPSINFO struct )

There is doing XML reading right, or doing the dodgy just to get by. Doing it right would be using proper document parsing.

Or... dodgy would be using custom text parsing with either wisuzu's response or using regular expressions with matchers.

"Bootstrapping" comes from the term "pulling yourself up by your own bootstraps." That much you can get from Wikipedia.

In computing, a bootstrap loader is the first piece of code that runs when a machine starts, and is responsible for loading the rest of the operating system. In modern computers it's stored in ROM, but I recall the bootstrap process on the PDP-11, where you would poke bits via the front-panel switches to load a particular disk segment into memory, and then run it. Needless to say, the bootstrap loader is normally pretty small.

"Bootstrapping" is also used as a term for building a system using itself -- or more correctly, a predecessor version. For example, ANTLR version 3 is written using a parser developed in ANTLR version 2.

Selenium WebDriver Java code:

Download Gecko Driver from https://github.com/mozilla/geckodriver/releases based on your platform. Extract it in a location by your choice. Write the following code:

System.setProperty("webdriver.gecko.driver", "D:/geckodriver-v0.16.1-win64/geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.lynda.com/Selenium-tutorials/Mastering-Selenium-Testing-Tools/521207-2.html");

One is an array of arrays, and one is a 2d array. The former can be jagged, the latter is uniform.

That is, a double[][] can validly be:

double[][] x = new double[5][];

x[0] = new double[10];
x[1] = new double[5];
x[2] = new double[3];
x[3] = new double[100];
x[4] = new double[1];

Because each entry in the array is a reference to an array of double. With a jagged array, you can do an assignment to an array like you want in your second example:

x[0] = new double[13];

On the second item, because it is a uniform 2d array, you can't assign a 1d array to a row or column, because you must index both the row and column, which gets you down to a single double:

double[,] ServicePoint = new double[10,9];

ServicePoint[0]... // <-- meaningless, a 2d array can't use just one index.

UPDATE:

To clarify based on your question, the reason your #1 had a syntax error is because you had this:

double[][] ServicePoint = new double[10][9];

And you can't specify the second index at the time of construction. The key is that ServicePoint is not a 2d array, but an 1d array (of arrays) and thus since you are creating a 1d array (of arrays), you specify only one index:

double[][] ServicePoint = new double[10][];

Then, when you create each item in the array, each of those are also arrays, so then you can specify their dimensions (which can be different, hence the term jagged array):

ServicePoint[0] = new double[13];
ServicePoint[1] = new double[20];

Hope that helps!

While:

1. entry control loop

2. condition is checked before loop execution

3. never execute loop if condition is false

4. there is no semicolon at the end of while statement

Do-while:

1. exit control loop

2. condition is checked at the end of loop

3. executes false condition at least once since condition is checked later

4. there is semicolon at the end of while statement.

Let's say there is an administrator dashboard where users are listed with their id printed as a data attribute so it can be retrieved at some point via JavaScript.

An update could be executed this way …

class UserRepository extends \Doctrine\ORM\EntityRepository
{
    public function updateUserStatus($userId, $newStatus)
    {
        return $this->createQueryBuilder('u')
            ->update()
            ->set('u.isActive', '?1')
            ->setParameter(1, $qb->expr()->literal($newStatus))
            ->where('u.id = ?2')
            ->setParameter(2, $qb->expr()->literal($userId))
            ->getQuery()
            ->getSingleScalarResult()
        ;
    }

AJAX action handling:

# Post datas may be:
# handled with a specific custom formType — OR — retrieved from request object
$userId = (int)$request->request->get('userId');
$newStatus = (int)$request->request->get('newStatus');
$em = $this->getDoctrine()->getManager();
$r = $em->getRepository('NAMESPACE\User')
        ->updateUserStatus($userId, $newStatus);
if ( !empty($r) ){
    # Row updated
}

Working example using Doctrine 2.5 (on top of Symfony3).

To generate classes from WSDL, all you need is build-helper-maven-plugin and jaxws-maven-plugin in your pom.xml
Make sure you have placed wsdl under folder src/main/resources/wsdl and corresponding schema in src/main/resources/schema, run command "mvn generate-sources" from Project root directory.

C:/Project root directory > mvn generate-sources

generated java classes can be located under folder

target/generated/src/main/java/com/raps/code/generate/ws.

I know this is an old thread, but I just cannot steer away from posting some useful info on this. I see the Zip question come up a lot and this answers nearlly most of the common questions.

To get around framework issues of using 4.5+... Their is a ZipStorer class created by jaime-olivares: https://github.com/jaime-olivares/zipstorer, he also has added an example of how to use this class as well and has also added an example of how to search for a specific filename as well.

And for reference on how to use this and iterate through for a certain file extension as example you could do this:

#region
/// <summary>
/// Custom Method - Check if 'string' has '.png' or '.PNG' extension.
/// </summary>
static bool HasPNGExtension(string filename)
{
    return Path.GetExtension(filename).Equals(".png", StringComparison.InvariantCultureIgnoreCase)
        || Path.GetExtension(filename).Equals(".PNG", StringComparison.InvariantCultureIgnoreCase);
}
#endregion

private void button1_Click(object sender, EventArgs e)
{
    //NOTE: I recommend you add path checking first here, added the below as example ONLY.
    string ZIPfileLocationHere = @"C:\Users\Name\Desktop\test.zip";
    string EXTRACTIONLocationHere = @"C:\Users\Name\Desktop";

    //Opens existing zip file.
    ZipStorer zip = ZipStorer.Open(ZIPfileLocationHere, FileAccess.Read);

    //Read all directory contents.
    List<ZipStorer.ZipFileEntry> dir = zip.ReadCentralDir();

    foreach (ZipStorer.ZipFileEntry entry in dir)
    {
        try
        {
            //If the files in the zip are "*.png or *.PNG" extract them.
            string path = Path.Combine(EXTRACTIONLocationHere, (entry.FilenameInZip));
            if (HasPNGExtension(path))
            {
                //Extract the file.
                zip.ExtractFile(entry, path);
            }
        }
        catch (InvalidDataException)
        {
            MessageBox.Show("Error: The ZIP file is invalid or corrupted");
            continue;
        }
        catch
        {
            MessageBox.Show("Error: An unknown error ocurred while processing the ZIP file.");
            continue;
        }
    }
    zip.Close();
}

If both data frames have the same column names then you should add one data frame inside ggplot() call and also name x and y values inside aes() of ggplot() call. Then add first geom_line() for the first line and add second geom_line() call with data=df2 (where df2 is your second data frame). If you need to have lines in different colors then add color= and name for eahc line inside aes() of each geom_line().

df1<-data.frame(x=1:10,y=rnorm(10))
df2<-data.frame(x=1:10,y=rnorm(10))

ggplot(df1,aes(x,y))+geom_line(aes(color="First line"))+
  geom_line(data=df2,aes(color="Second line"))+
  labs(color="Legend text")

Older IE and Firefox browsers attach the scrollbar to the documentElement, or what would be the <html> tag in HTML.

All other browsers attach the scrollbar to document.body, or what would be the <body> tag in HTML.

The correct solution would be to check which one to use, depending on browser

var doc = document.documentElement.clientHeight ? document.documentElement : document.body;
var s   = $(doc).scrollTop();

jQuery does make this a little easier, when passing in either window or document jQuery's scrollTop does a similar check and figures it out, so either of these should work cross-browser

var s = $(document).scrollTop();

or

var s = $(window).scrollTop();

jQuery scrollTop() docs

Description: Get the current vertical position of the scroll bar for the first element in the set of matched elements or set the vertical position of the scroll bar for every matched element.

...nothing that works for my div, just the full page

If it's for a DIV, you'd have to target the element that has the scrollbar attached, to get the scrolled amount

$('div').scrollTop();

If you need to get the elements distance from the top of the document, you can also do

$('div').offset().top

I added opacity to the line, so it seems thinner:

<hr style="opacity: 0.25">

How about .delay() ?

http://api.jquery.com/delay/

$("#test").animate({"top":"-=80px"},1500)
          .delay(1000)
          .animate({"opacity":"0"},500);

What I have observed is: if you use openssl to generate certificates, it captures both the text part and the base64 certificate part in the crt file. The strict pem format says (wiki definition) that the file should start and end with BEGIN and END.

.pem – (Privacy Enhanced Mail) Base64 encoded DER certificate, enclosed between "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----"

So for some libraries (I encountered this in java) that expect strict pem format, the generated crt would fail the validation as an 'invalid pem format'.

Even if you copy or grep the lines with BEGIN/END CERTIFICATE, and paste it in a cert.pem file, it should work.

Here is what I do, not very clean, but works for me, basically it filters the text starting from BEGIN line:

grep -A 1000 BEGIN cert.crt > cert.pem

Lets understand it with the following simple example. This happens because this is NON-STATIC INNER CLASS. You should need the instance of outer class.

 public class PQ {

    public static void main(String[] args) {

        // create dog object here
        Dog dog = new PQ().new Dog();
        //OR
        PQ pq = new PQ();
        Dog dog1 = pq.new Dog();
    }

    abstract class Animal {
        abstract void checkup();
    }

    class Dog extends Animal {
        @Override
        void checkup() {
            System.out.println("Dog checkup");

        }
    }

    class Cat extends Animal {
        @Override
        void checkup() {
            System.out.println("Cat Checkup");

        }
    }
}

I find myself using the following often to get a limited number of revisions out of our huge subversion tree (we're soon reaching svn revision 35000).

# checkout a specific revision
git svn clone -r N svn://some/repo/branch/some-branch
# enter it and get all commits since revision 'N'
cd some-branch
git svn rebase

And a good way to find out where a branch started is to do a svn log it and find the first one on the branch (the last one listed when doing):

svn log --stop-on-copy svn://some/repo/branch/some-branch

So far I have not really found the hassle worth it in tracking all branches. It takes too much time to clone and svn and git don't work together as good as I would like. I tend to create patch files and apply them on the git clone of another svn branch.

I normally test by running the job i created like this:

It is easier to use two terminals to do this.

run job:

#./jobname.sh

go to:

#/var/log and run 

run the following:

#tailf /var/log/cron

This allows me to see the cron logs update in real time. You can also review the log after you run it, I prefer watching in real time.

Here is an example of a simple cron job. Running a yum update...

#!/bin/bash
YUM=/usr/bin/yum
$YUM -y -R 120 -d 0 -e 0 update yum
$YUM -y -R 10 -e 0 -d 0 update

Here is the breakdown:

First command will update yum itself and next will apply system updates.

-R 120 : Sets the maximum amount of time yum will wait before performing a command

-e 0 : Sets the error level to 0 (range 0 - 10). 0 means print only critical errors about which you must be told.

-d 0 : Sets the debugging level to 0 - turns up or down the amount of things that are printed. (range: 0 - 10).

-y : Assume yes; assume that the answer to any question which would be asked is yes

After I built the cron job I ran the below command to make my job executable.

#chmod +x /etc/cron.daily/jobname.sh 

Hope this helps, Dorlack

Usually when i try to find my public IP Address like cmyip.com or www.iplocation.net, i use this way:

public static String myPublicIp() {

    /*nslookup myip.opendns.com resolver1.opendns.com*/
    String ipAdressDns  = "";
    try {
        String command = "nslookup myip.opendns.com resolver1.opendns.com";
        Process proc = Runtime.getRuntime().exec(command);

        BufferedReader stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream()));

        String s;
        while ((s = stdInput.readLine()) != null) {
            ipAdressDns  += s + "\n";
        }
    } catch (IOException e) {
        e.printStackTrace();
    }

    return ipAdressDns ;
}

Instead of "w" use "a" (append) mode with open function:

with open("games.txt", "a") as text_file:

No Dapper answer here. So I added one

using Dapper;
using System.Data.SqlClient;

using (var cn = new SqlConnection(@"Server=(local);DataBase=master;Integrated Security=SSPI"))
    cn.Execute("dbo.test", commandType: CommandType.StoredProcedure);

The other answers point out how to accomplish this, but you should keep in mind the consequences since this is a remote repository.

The git tag man page, in the On Retagging section, has a good explanation of how to courteously inform the remote repo's other users of the change. They even give a handy announcement template for communicating how others should get your changes.

You can use double quotes if ANSI SQL mode is enabled

  (
     id    INTEGER PRIMARY KEY AUTO_INCREMENT NOT NULL,
     "key" TEXT UNIQUE NOT NULL,
     value TEXT NOT NULL
  )

or the proprietary back tick escaping otherwise. (Where to find the ` character on various keyboard layouts is covered in this answer)

CREATE TABLE IF NOT EXISTS misc_info
  (
     id    INTEGER PRIMARY KEY AUTO_INCREMENT NOT NULL,
     `key` TEXT UNIQUE NOT NULL,

An index that contains (or "covers") all the data needed to satisfy a query is called a covering index.

When you issue a query that is covered by an index (an indexed-covered query), you'll see "Using Index" in the Extra column in EXPLAIN.

A DLL is a library of functions that are shared among other executable programs. Just look in your windows/system32 directory and you will find dozens of them. When your program creates a DLL it also normally creates a lib file so that the application *.exe program can resolve symbols that are declared in the DLL.

A .lib is a library of functions that are statically linked to a program -- they are NOT shared by other programs. Each program that links with a *.lib file has all the code in that file. If you have two programs A.exe and B.exe that link with C.lib then each A and B will both contain the code in C.lib.

How you create DLLs and libs depend on the compiler you use. Each compiler does it differently.

You write like this-:

xAxis: {
        type: 'datetime',
        dateTimeLabelFormats: {
           day: '%d %b %Y'    //ex- 01 Jan 2016
        }
}

also check for other datetime format

After trying a lot of passwords and becoming totally confused why my public key password is not working I found out that I have to use vagrant as password.

Maybe this info helps someone else too - that's because I've written it down here.

Edit:
According to the Vagrant documentation, there is usually a default password for the user vagrant which is vagrant.
Read more on here: official website

In recent versions however, they have moved to generating keypairs for each machine. If you would like to find out where that key is, you can run vagrant ssh -- -v. This will show the verbose output of the ssh login process. You should see a line like

debug1: Trying private key: /home/aaron/Documents/VMs/.vagrant/machines/default/virtualbox/private_key

I had this error aswell.

I am working in mysql workbench. When giving the values they have to be inside "". That solved it for me.

You can simply do the following:

    [HttpGet]
    public async Task<IActionResult> GetAsync()
    {
        string queryString = Request.QueryString.ToString().ToLower();

        return Ok(await DoMagic.GetAuthorizationTokenAsync(new Uri($"https://someurl.com/token-endpoint{queryString}")));
    }

If you need to access each element separately, simply refer to Request.Query.

You must set your query base to the DN of the user in question, then set your filter to the DN of the group you're wondering if they're a member of. To see if jdoe is a member of the office group then your query will look something like this:

ldapsearch -x -D "ldap_user" -w "user_passwd" -b "cn=jdoe,dc=example,dc=local" -h ldap_host '(memberof=cn=officegroup,dc=example,dc=local)'

If you want to see ALL the groups he's a member of, just request only the 'memberof' attribute in your search, like this:

ldapsearch -x -D "ldap_user" -w "user_passwd" -b "cn=jdoe,dc=example,dc=local" -h ldap_host **memberof**

Having trouble wrapping my head around this.

Have a rewrite rule with four conditions.
The first three conditions A, B, C are to be AND which is then OR with D

RewriteCond A       true
RewriteCond B       false
RewriteCond C [OR]  true
RewriteCond D       true
RewriteRule ...

But that seems to be an expression of A and B and (C or D) = false (don't rewrite)

How can I get to the desired expression? (A and B and C) or D = true (rewrite)

Preferably without using the additional steps of setting environment variables.

A simple way to protect a file with no requirement for a separate login page - just add this to the top of the page:

Change secretuser and secretpassword to your user/password.

$user = $_POST['user'];
$pass = $_POST['pass'];

if(!($user == "secretuser" && $pass == "secretpassword"))
{
    echo '<html><body><form method="POST" action="'.$_SERVER['REQUEST_URI'].'">
            Username: <input type="text" name="user"></input><br/>

JavaScript code:
    function passFileUrl(){
    document.getElementById('asgnmnt_file').click();
    }

    function fileSelected(inputData){
    document.getElementById('asgnmnt_file_img').src = window.URL.createObjectURL(inputData.files[0])

You can use the "Objects" class from JAVA (which is available since 1.7)

Collection<String> myCollection = Arrays.asList("1273","123","876","897");
Objects.toString(myCollection);

Output: 1273, 123, 876, 897

Another possibility is to use the "MoreObjects" class from Google Guave, which provides many of useful helper functions:

MoreObjects.toStringHelper(this).add("NameOfYourObject", myCollection).toString());

Output: NameOfYourObject=[1273, 123, 876, 897]

It wasn't working for me either. vbcrlf and Environment.Newline() both had no effect. My problem was that the Placeholder Properties had a Markup type of HTML. When I changed it to None, it worked like a champ!

Short answer: it's closely related to the Content-Security-Policy: upgrade-insecure-requests response header, indicating that the browser supports it (and in fact prefers it).

It took me 30mins of Googling, but I finally found it buried in the W3 spec.

The confusion comes because the header in the spec was HTTPS: 1, and this is how Chromium implemented it, but after this broke lots of websites that were poorly coded (particularly WordPress and WooCommerce) the Chromium team apologized:

"I apologize for the breakage; I apparently underestimated the impact based on the feedback during dev and beta."
— Mike West, in Chrome Issue 501842

Their fix was to rename it to Upgrade-Insecure-Requests: 1, and the spec has since been updated to match.

Anyway, here is the explanation from the W3 spec (as it appeared at the time)...

The HTTPS HTTP request header field sends a signal to the server expressing the client’s preference for an encrypted and authenticated response, and that it can successfully handle the upgrade-insecure-requests directive in order to make that preference as seamless as possible to provide.

...

When a server encounters this preference in an HTTP request’s headers, it SHOULD redirect the user to a potentially secure representation of the resource being requested.

When a server encounters this preference in an HTTPS request’s headers, it SHOULD include a Strict-Transport-Security header in the response if the request’s host is HSTS-safe or conditionally HSTS-safe [RFC6797].

I had the same problem. Got the following message when I tried to commit:

hg debuglock showed this:

Oracle JRockit, which can handle a non-contiguous heap, can have a Java heap size of 2.85 GB on Windows 2003/XP with the /3GB switch. It seems that fragmentation can have quite an impact on how large a Java heap can be.

The following are some comparisons:

String s1 = "Hello";
String s2 = "Hello";
String s3 = new String("Hello");

System.out.println(s1 == s2); //true
System.out.println(s1.equals(s2)); //true

System.out.println(s1 == s3);   //false
System.out.println(s1.equals(s3)); //true

s3 = s3.intern();
System.out.println(s1 == s3); //true
System.out.println(s1.equals(s3)); //true

When intern() is called the reference is changed.

Your syntax is incorrect. The var keyword in your for loop must be followed by a variable name, in this case its propName

var propValue;
for(var propName in nyc) {
    propValue = nyc[propName]

    console.log(propName,propValue);
}

You can use Replace function as;

REPLACE ('Your String with cityname here', 'cityname', 'xyz')
--Results
'Your String with xyz here'

If you apply this to a table column where stringColumnName, cityName both are columns of YourTable

SELECT REPLACE(stringColumnName, cityName, '')
FROM YourTable

Or if you want to remove 'cityName' string from out put of a column then

SELECT REPLACE(stringColumnName, 'cityName', '')
FROM yourTable

EDIT: Since you have given more details now, REPLACE function is not the best method to sort your problem. Following is another way of doing it. Also @MartinSmith has given a good answer. Now you have the choice to select again.

SELECT RIGHT (O.Ort, LEN(O.Ort) - LEN(C.CityName)-1) As WithoutCityName
FROM   tblOrtsteileGeo O
       JOIN dbo.Cities C
         ON C.foo = O.foo

Based on the other answers, here is a first draft for usage with knockout:

Usage

      <div data-bind="editableSelect: {options: optionsObservable, value: nameObservable}"></div>

Knockout data binding

composition.addBindingHandler('editableSelect',
  {
    init: function(hostElement, valueAccessor) {

      var optionsObservable = getOptionsObservable();
      var valueObservable = getValueObservable();

      var $editableSelect = $(hostElement);
      $editableSelect.addClass('select-editable');

      var editableSelect = $editableSelect[0];

      var viewModel = new editableSelectViewModel(optionsObservable, valueObservable);
      ko.applyBindingsToNode(editableSelect, { compose: viewModel });

      //tell knockout to not apply bindings twice
      return { controlsDescendantBindings: true };

      function getOptionsObservable() {
        var accessor = valueAccessor();
        return getAttribute(accessor, 'options');
      }

      function getValueObservable() {
        var accessor = valueAccessor();
        return getAttribute(accessor, 'value');
      }
    }
  });

View

<select
  data-bind="options: options, event:{ focus: resetComboBoxValue, change: setTextFieldValue} "
  id="comboBox"
  ></select>
<input
  data-bind="value: value, , event:{ focus: textFieldGotFocus, focusout: textFieldLostFocus}"
  id="textField"
  type="text"/>

ViewModel

define([
  'lodash',
  'services/errorHandler'
], function(
  _,
  errorhandler
) {

  var viewModel = function(optionsObservable, valueObservable) {

    var self = this;
    self.options = optionsObservable();
    self.value = valueObservable;
    self.resetComboBoxValue = resetComboBoxValue;
    self.setTextFieldValue = setTextFieldValue;
    self.textFieldGotFocus = textFieldGotFocus;
    self.textFieldLostFocus = textFieldLostFocus;

    function resetComboBoxValue() {
      $('#comboBox').val(null);
    }

    function setTextFieldValue() {
      var selection = $('#comboBox').val();
      self.value(selection);
    }

    function textFieldGotFocus() {
      $('#comboBox').addClass('select-editable-input-focus');

    }

    function textFieldLostFocus() {
      $('#comboBox').removeClass('select-editable-input-focus');
    }

  };
  errorhandler.includeIn(viewModel);

  return viewModel;
});

This is an addition to Josh's answer.

You can also keep the values of other variables while filtering out duplicated rows in data.table

Example:

library(data.table)

#create data table
dt <- data.table(
  V1=LETTERS[c(1,1,1,1,2,3,3,5,7,1)],
  V2=LETTERS[c(2,3,4,2,1,4,4,6,7,2)],
  V3=c(1),
  V4=c(2) )

> dt
# V1 V2 V3 V4
# A  B  1  2
# A  C  1  2
# A  D  1  2
# A  B  1  2
# B  A  1  2
# C  D  1  2
# C  D  1  2
# E  F  1  2
# G  G  1  2
# A  B  1  2

# set the key to all columns
setkey(dt)

# Get Unique lines in the data table
unique( dt[list(V1, V2), nomatch = 0] ) 

# V1 V2 V3 V4
# A  B  1  2
# A  C  1  2
# A  D  1  2
# B  A  1  2
# C  D  1  2
# E  F  1  2
# G  G  1  2

Alert: If there are different combinations of values in the other variables, then your result will be

unique combination of V1 and V2

The answer is on the example link you provided:

http://getbootstrap.com/javascript/#modals-usage

i.e.

Call a modal with id myModal with a single line of JavaScript:

$('#myModal').modal('show');

Just use flex! Make sure to use body and main in your HTML and it's one of the best solutions (unless you need IE9 support). It doesn't require a fixed height or similiar.

That's recommended for Materialize as well!

body {
    display: flex;
    min-height: 100vh;
    flex-direction: column;
}

main {
    flex: 1 0 auto;
}

The paths for msysgit are:

Windows XP -C:\Documents and Settings\<user_name>\.gitconfig

Windows Vista+ C:\Users\<user_name>\.gitconfig

Some of the data processing requirements doesn't need sort at all. Syncsort had made the sorting in Hadoop pluggable. Here is a nice blog from them on sorting. The process of moving the data from the mappers to the reducers is called shuffling, check this article for more information on the same.

Adding/Removing value dynamically without hard-code:

// remove value from select dynamically

$("#id-select option[value='" + dynamicVal + "']").remove();

// Add dynamic value to select

$("#id-select").append('<option value="' + dynamicVal + '">' + dynamicVal + '</option>');

Normally, it's considered poor style to unnecessarily cast pointers to (void*). Here, however, you need the casts to (void*) on the printf arguments because printf is variadic. The prototype doesn't tell the compiler what type to convert the pointers to at the call site.

By the following code, I am able to get adobe application shared pdf file as a stream and saving into android application path

Android.Net.Uri fileuri =
    (Android.Net.Uri)Intent.GetParcelableExtra(Intent.ExtraStream);

    fileuri i am getting as {content://com.adobe.reader.fileprovider/root_external/
                                        data/data/com.adobe.reader/files/Downloads/sample.pdf}

    string filePath = fileuri.Path;

   filePath I am gettings as root_external/data/data/com.adobe.reader/files/Download/sample.pdf

      using (var stream = ContentResolver.OpenInputStream(fileuri))
      {
       byte[] fileByteArray = ToByteArray(stream); //only once you can read bytes from stream second time onwards it has zero bytes

       string fileDestinationPath ="<path of your destination> "
       convertByteArrayToPDF(fileByteArray, fileDestinationPath);//here pdf copied to your destination path
       }
     public static byte[] ToByteArray(Stream stream)
        {
            var bytes = new List<byte>();

            int b;
            while ((b = stream.ReadByte()) != -1)
                bytes.Add((byte)b);

            return bytes.ToArray();
        }

      public static string convertByteArrayToPDF(byte[] pdfByteArray, string filePath)
        {

            try
            {
                Java.IO.File data = new Java.IO.File(filePath);
                Java.IO.OutputStream outPut = new Java.IO.FileOutputStream(data);
                outPut.Write(pdfByteArray);
                return data.AbsolutePath;

            }
            catch (System.Exception ex)
            {
                return string.Empty;
            }
        }

The big difference is that the first example actually invokes the lambda f(x), while the second example doesn't.

Your first example is equivalent to [(lambda x: x*x)(x) for x in range(10)] while your second example is equivalent to [f for x in range(10)].

3. my api method

define globle

private List<DataResponse> dataResponses = new ArrayList<>();

    private void volleyAutomation(String url) {
            JSONArray array = new JSONArray();
            JsonArrayRequest request_json = new JsonArrayRequest(Request.Method.GET, url, array,
                    new Response.Listener<JSONArray>() {
                        @Override
                        public void onResponse(JSONArray response) {
    
                            GsonBuilder gsonBuilder = new GsonBuilder();
                            Gson gson = gsonBuilder.create();
                           dataResponses = Arrays.asList(gson.fromJson(response.toString(), DataResponse[].class));
    
                            rvList(dataResponses);
                            Log.d("respknce___", String.valueOf(dataResponses.size()));
                        }
                    }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError volleyError) {
    
                }
            });
            RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
            requestQueue.add(request_json);
        }

You can try this.

import csv
import pandas as pd
df = pd.read_csv(filepath,encoding='unicode_escape')

What is your reason for excluding all transitive dependencies?

If there is a particular artifact (such as commons-logging) which you need to exclude from every dependency, the Version 99 Does Not Exist approach might help.

Update 2012: Don't use this approach. Use maven-enforcer-plugin and exclusions. Version 99 produces bogus dependencies and the Version 99 repository is offline (there are similar mirrors but you can't rely on them to stay online forever either; it's best to use only Maven Central).

Just in case you actually mean 'discard changes' whenever you use 'git stash' (and don't really use git stash to stash it temporarily), in that case you can use

git checkout -- <file>

Note that git stash is just a quicker and simple alternative to branching and doing stuff.

The solution:

var list = (from t in ctn.Items
           where t.DeliverySelection == true && t.Delivery.SentForDelivery == null
           orderby t.Delivery.SubmissionDate
           select t).Take(5);

I wanted to checkout a single file to a directory, which was not part of a working copy.

Let's get the file at the following URL: http://subversion.repository.server/repository/module/directory/myfile

svn co  http://subversion.repository.server/repository/module/directory/myfile /**directoryb**

So I checked out the given directory containing the target file I wanted to get to a dummy directory, (say etcb for the URL ending with /etc).

Then I emptied the file .svn/entries from all files of the target directory I didn't needed, to leave just the file I wanted. In this .svn/entries file, you have a record for each file with its attributes so leave just the record concerning the file you want to get and save.

Now you need just to copy then ''.svn'' to the directory which will be a new "working copy". Then you just need to:

cp .svn /directory
cd /directory
svn update myfile

Now the directory directory is under version control. Do not forget to remove the directory directoryb which was just a ''temporary working copy''.

ADD this single line code in your App Delegate - Did Finish Lauch. It will change Font, color of navigation bar throughout the application.

UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white, NSAttributedString.Key.font: UIFont(name: "YOUR FONT NAME", size: 25.0)!]

If you have to test more than one string in the same validation, you can do something like this:

import java.util.Optional;
import java.util.function.Predicate;
import java.util.stream.Stream;

public class StringHelper {

  public static Boolean hasBlank(String ... strings) {

    Predicate<String> isBlank = s -> s == null || s.trim().isEmpty();

    return Optional
      .ofNullable(strings)
      .map(Stream::of)
      .map(stream -> stream.anyMatch(isBlank))
      .orElse(false);
  }

}

So, you can use this like StringHelper.hasBlank("Hello", null, "", " ") or StringHelper.hasBlank("Hello") in a generic form.

You could use the rename() function :

rename('foo/test.php', 'bar/test.php');

This however will move the file not copy

So I just had this same issue, but a little different. I already had the icon as an object as Philippe Boissonneault suggests, but I was using an SVG image.

What solved it for me was:
Switch from an SVG image to a PNG and following Catherine Nyo on having an image that is double the size of what you will use.

This is a very confusing topic. django stores all applied migrations in a table called django_migrations. perform this sql ( i am using postgres . so in query tool section)

select * from django_migrations where app='your appname'  (app in which u have issue with).

This will list all applied migrations for that app.
Go to your app/migration folder and check all migrations . find the migration file associated with your error . file where your table was created or column added or modified.
look for the id of this migration file in django_migrations table( select * from django_migrations where app='your app') .

Then do :

delete from django_migrations where id='id of your migration';

delete multiple id's if you have multiple migrations file associated with your issue.

now reapply migrate

Python manage.py migrate yourappname

second option

1. Drop tables in your app where you have issue.

2. delete all migrations for that app from app/migrations folder.(don't delete init.py from that folder).

3. now run

   python manage.py makemigrations appname

4. now run

python manage.py migrate appname

How about ByteArrayInputStream?

The first answer mentioned how to get the description property programatically. If you're going to bother with program anyway, since the comments in the query are so kludgy, instead of trying to put the comments in the query, maybe it's better to put them in a program and use the program to make all your queries

Dim dbs As DAO.Database
Dim qry As DAO.QueryDef

Set dbs = CurrentDb
'put your comments wherever in your program makes the most sense
dbs.QueryDefs("qryName").SQL = "SELECT whatever.fields FROM whatever_table;"
DoCmd.OpenQuery "qryname"

You should analyze your style.css file, possibly using Developer Tools in your favorite browser, to see which rule sets font size on the element in a manner that overrides the one in a style attribute. Apparently, it has to be one using the !important specifier, which generally indicates poor logic and structure in styling.

Primarily, modify the style.css file so that it does not use !important. Failing this, add !important to the rule in style attribute. But you should aim at reducing the use of !important, not increasing it.

Instead of using @Controller and @ResponseBody, @RestController let's you expose Rest APIs in Spring 4.0 and above.

I was just playing around with this, too. One way you can add extra weight is in the ORDER BY area of the code.

For example, if you were matching 3 different columns and wanted to more heavily weight certain columns:

SELECT search.*,
MATCH (name) AGAINST ('black' IN BOOLEAN MODE) AS name_match,
MATCH (keywords) AGAINST ('black' IN BOOLEAN MODE) AS keyword_match,
MATCH (description) AGAINST ('black' IN BOOLEAN MODE) AS description_match
FROM search
WHERE MATCH (name, keywords, description) AGAINST ('black' IN BOOLEAN MODE)
ORDER BY (name_match * 3  + keyword_match * 2  + description_match) DESC LIMIT 0,100;
