strace sqlplus -L scott/tiger@orcl helps to find .tnsnames.ora file on /home/oracle to find the file it takes instead of $ORACLE_HOME/network/admin/tnsnames.ora file. Thanks for the posting.

Step 1 – Check the DB listener status

   lsnrctl status

Notice that the listener you want (in our case “orcl”) is not showing.

Step 2 – Login via sqlplus

   sqlplus sys/oracle as sysdba

Sqlplus gave us this error message:

   Writing audit records to Windows Event Log failed

Step 3 – Go into the Windows Event Viewer (eventvwr.exe)

Under “Windows Logs”, right click on Application and select “Clear Log”. Do the same for System.

It may also be wise to right click on Application and select Properties. Then, under “Log Size” select the following option under “When maximum log size is reached”: “Overwrite events as needed”. This should prevent the log from maxing out and causing the DB not to start.

In Windows Vista and higher, you can execute the following command to clear the Application log:

   wevtutil cl Application

Step 4 – Login via sqlplus

   sqlplus sys/oracle as sysdba

You should now be able to login with no error messages.

Step 5 - Check the DB listener status

   lsnrctl status

You should now see your listener running.

Step 6 – Start UCM

UCM should now start up.

For a more in-depth answer to this question you can read my full blog post.

You most certainly have a databases tab in sql developer (all versions I've used in the past have this). Maybe check again? Perhaps, you're looking in the wrong location.

On a mac, the preferences is under "Oracle SQL Developer" (top left) -> Preferences -> Database -> Advanced -> section called Tnsnames Directory is where you specify the file.

On windows (going from memory so might have to search if this isn't correct) Tools -> Preferences -> Database -> Advanced -> section called Tnsnames Directory is where you specify the file.

See this image

To avoid all the Oracle mess of not knowing where it is looking for the TNSNAMES.ORA (I have the added confusion of multiple Oracle versions and 32/64 bit), you can copy the setting from your existing TNSNAMES.ORA to your own config file and use that for your connection.
Say you're happy with the 'DSDSDS' reference in TNSNAMES.ORA which maps to something like:

DSDSDS=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(Host=DSDSDSHost)(Port=4521)))(CONNECT_DATA=(SERVICE_NAME=DSDSDSService)))

On the newer versions of macOS, one also has to set java.library.path. The easiest/safest way to do that [1] is by creating ~/.sqldeveloper/<version>/sqldeveloper.conf file and populating it as such:

AddVMOption -Djava.library.path=<instant client directory>

[1] https://community.oracle.com/message/14132189#14132189

Also in addition to above solutions, also check the location where the tnsname ora file exists and compare with the path in the environment variable

You can always find out the location of the tnsnames.ora file being used by running TNSPING to check connectivity (9i or later):

C:\>tnsping dev

TNS Ping Utility for 32-bit Windows: Version 10.2.0.1.0 - Production on 08-JAN-2009 12:48:38

Copyright (c) 1997, 2005, Oracle.  All rights reserved.

Used parameter files:
C:\oracle\product\10.2.0\client_1\NETWORK\ADMIN\sqlnet.ora


Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = XXX)(PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME = DEV)))
OK (30 msec)

C:\>

Sometimes, the problem is with the entry you made in tnsnames.ora, not that the system can't find it. That said, I agree that having a tns_admin environment variable set is a Good Thing, since it avoids the inevitable issues that arise with determining exactly which tnsnames file is being used in systems with multiple oracle homes.

Perhaps using SIMILAR TO would work ?

SELECT * from table WHERE column SIMILAR TO '(AAA|BBB|CCC)%';

In IIS Manager, in the advanced settings of the Application Pool, make sure "Process Model ? Load User Profile" is set to "True". In my case it worked.

Use document.scrollTop to change the position of the document. Set the scrollTop of the document equal to the bottom of the featured section of your site

IMO the best way to accomplish your goal is to display a numeric keyboard rather than the normal keyboard. This restricts which keys are available to the user. This alleviates the need to do validation, and more importantly it prevents the user from making a mistake. The number pad is also much nicer for entering numbers because the keys are substantially larger.

In interface builder select the UITextField, go to the Attributes Inspector and change the "Keyboard Type" to "Decimal Pad".

That'll make the keyboard look like this:

The only thing left to do is ensure the user doesn't enter in two decimal places. You can do this while they're editing. Add the following code to your view controller. This code removes a second decimal place as soon as it is entered. It appears to the user as if the 2nd decimal never appeared in the first place.

- (void)viewDidLoad
{
  [super viewDidLoad];

  [self.textField addTarget:self
                    action:@selector(textFieldDidChange:)
           forControlEvents:UIControlEventEditingChanged];
}

- (void)textFieldDidChange:(UITextField *)textField
{
  NSString *text = textField.text;
  NSRange range = [text rangeOfString:@"."];

  if (range.location != NSNotFound &&
      [text hasSuffix:@"."] &&
      range.location != (text.length - 1))
  {
    // There's more than one decimal
    textField.text = [text substringToIndex:text.length - 1];
  }
}

With Python 3.8 this workes for me. For instance to execute a python script within the venv:

    import subprocess
    import sys
    res = subprocess.run([
              sys.executable,            # venv3.8/bin/python
              'main.py', '--help',], 
            stdout=PIPE, 
            text=True)
    print(res.stdout)

I only needed the environment variables locally to invoke my test command, here's an example setting multiple environment vars in a bash shell, and escaping the dollar sign in make.

SHELL := /bin/bash

.PHONY: test tests
test tests:
    PATH=./node_modules/.bin/:$$PATH \
    JSCOVERAGE=1 \
    nodeunit tests/

Based on the proposed solution by @blootsvoets, I edited my jar target this way :

jar {
    manifest {
        attributes('Main-Class': 'eu.tib.sre.Main')
    }
    // Include the classpath from the dependencies 
    from { configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) } }
    // This help solve the issue with jar lunch
    {
    exclude "META-INF/*.SF"
    exclude "META-INF/*.DSA"
    exclude "META-INF/*.RSA"
  }
}

Random ra = new Random();
int r, g, b;
r=ra.nextInt(255);
g=ra.nextInt(255);
b=ra.nextInt(255);
Color color = new Color(r,g,b);
String hex = Integer.toHexString(color.getRGB() & 0xffffff);
if (hex.length() < 6) {
    hex = "0" + hex;
}
hex = "#" + hex;

BigDecimal value = new BigDecimal(10.0000);
value.setScale(4);

msg * /time:0 /w Hello everybody!

This message waits forever until OK is clicked (it lasts only one minute by default) and works fine in Windows 8.1

I just made a pure Javascript function based on that code. Javascript only version demo: http://jsbin.com/copidifiji

That is the independent code from jQuery

if (window.addEventListener) {window.addEventListener('DOMMouseScroll', wheel, false); 
window.onmousewheel = document.onmousewheel = wheel;}

function wheel(event) {
    var delta = 0;
    if (event.wheelDelta) delta = (event.wheelDelta)/120 ;
    else if (event.detail) delta = -(event.detail)/3;

    handle(delta);
    if (event.preventDefault) event.preventDefault();
    event.returnValue = false;
}

function handle(sentido) {
    var inicial = document.body.scrollTop;
    var time = 1000;
    var distance = 200;
  animate({
    delay: 0,
    duration: time,
    delta: function(p) {return p;},
    step: function(delta) {
window.scrollTo(0, inicial-distance*delta*sentido);   
    }});}

function animate(opts) {
  var start = new Date();
  var id = setInterval(function() {
    var timePassed = new Date() - start;
    var progress = (timePassed / opts.duration);
    if (progress > 1) {progress = 1;}
    var delta = opts.delta(progress);
    opts.step(delta);
    if (progress == 1) {clearInterval(id);}}, opts.delay || 10);
}

Previous anwser works fine. I would just add that you dont need to specify CURLOPT_POSTFIELDS as "xmlRequest=" . $input_xml to read your $_POST. You can use file_get_contents('php://input') to get the raw post data as plain XML.

You are creating a dictionary first, then passing that dictionary to an OrderedDict. For Python versions < 3.6 ^(*), by the time you do that, the ordering is no longer going to be correct. dict is inherently not ordered.

Pass in a sequence of tuples instead:

ship = [("NAME", "Albatross"),
        ("HP", 50),
        ("BLASTERS", 13),
        ("THRUSTERS", 18),
        ("PRICE", 250)]
ship = collections.OrderedDict(ship)

What you see when you print the OrderedDict is it's representation, and it is entirely correct. OrderedDict([('PRICE', 250), ('HP', 50), ('NAME', 'Albatross'), ('BLASTERS', 13), ('THRUSTERS', 18)]) just shows you, in a reproducable representation, what the contents are of the OrderedDict.

^(*): In the CPython 3.6 implementation, the dict type was updated to use a more memory efficient internal structure that has the happy side effect of preserving insertion order, and by extension the code shown in the question works without issues. As of Python 3.7, the Python language specification has been updated to require that all Python implementations must follow this behaviour. See this other answer of mine for details and also why you'd still may want to use an OrderedDict() for certain cases.

You can also look into using the Collection Object. This usually works better than an array for custom objects, since it dynamically sizes and has methods for:

• Add
• Count
• Remove
• Item(index)

Plus its normally easier to loop through a collection too since you can use the for...each structure very easily with a collection.

I solved this problem pretty elegantly using Package Level Annotations and then making that annotation have as an argument a list of classes.

Find Java classes implementing an interface

Implementations just have to create a package-info.java and put the magic annotation in with the list of classes they want to support.

To everyone struggling, what worked for me was creating personal access token and then using it as a username AND password (in the prompt that opened).

$(document).on("click", function(event){
   var a = $(event.target).parents();
   var flaghide = true;
    a.each(function(index, val){
       if(val == $(container)[0]){
           flaghide = false;
        }
    });
    if(flaghide == true){
        //required code
    }
})

It works for me on Ubuntu...
cd var/lib/tomcat7
sudo nano logs/catalina.out

This is the code to create dropdown in Angular 7, 8, 9

.html file code

<div>
<label>Summary: </label>
<select (change)="SelectItem($event.target.value)" class="select">
  <option value="0">--All--</option>
  <option *ngFor="let item of items" value="{{item.Id.Value}}">
    {{item.Name}}
  </option>
</select>
</div>

.ts file code

SelectItem(filterVal: any)
{
    var id=filterVal;
    //code
}

items is an array which should be initialized in .ts file.

I know there is an accepted answer but I recommend

Simple REST Client Extension for Chrome.

example:

Implement toString() on the class.

I recommend the Apache Commons ToStringBuilder to make this easier. With it, you just have to write this sort of method:

public String toString() {
     return new ToStringBuilder(this).
       append("name", name).
       append("age", age).
       toString(); 
}

In order to get this sort of output:

Person@7f54[name=Stephen,age=29]

There is also a reflective implementation.

Just a silly mistake use quote('') in '200px'

 <html>
  <head>    
  </head>

<body >
    <button type="button" onClick = "document.getElementById('chartdiv').style.height = '200px';">Click Me!</button>
    <div id="chartdiv" style="width: 100%; height: 50px; background-color:#E8EDF2"></div>
</body>

You can call a function from within a class with:

A().method1()

On DataTable 1.9.x:

$('.dataTable').dataTable({
    'aoColumnDefs': [{
        'bSortable': false,
        'aTargets': [-1], /* 1st colomn, starting from the right */
    }]
});

While on 1.10.x

$('.dataTable').dataTable({
    columnDefs: [{ orderable: false, "targets": -1 }] /* -1 = 1st colomn, starting from the right */
});

The solution from Edward worked for me.

If you want the whole tablix on one sheet with a constant name, specify the PageName in the tablix's Properties. If you set the PageName in the tablix's Properties, you can not use data from the tablix's dataset in your expression.

If you want rows from the tablix grouped into sheets (or you want one sheet with a name based on the data), specify the PageName in the Group Header.

If you mean if you can do ctor chaining in C#, the answer is yes. The question has already been asked.

However it seems from the comments, it seems what you really intend to ask is 'Can I call an overloaded constructor from within another constructor with pre/post processing?'
Although C# doesn't have the syntax to do this, you could do this with a common initialization function (like you would do in C++ which doesn't support ctor chaining)

class A
{
  //ctor chaining
  public A() : this(0)
  {  
      Console.WriteLine("default ctor"); 
  }

  public A(int i)
  {  
      Init(i); 
  }

  // what you want
  public A(string s)
  {  
      Console.WriteLine("string ctor overload" );
      Console.WriteLine("pre-processing" );
      Init(Int32.Parse(s));
      Console.WriteLine("post-processing" );
  }

   private void Init(int i)
   {
      Console.WriteLine("int ctor {0}", i);
   }
}

In my case (quasar and command quasar dev for testing), I just forgot to restart dev Quasar command.

It seemed to me that components was automatically loaded when any change was done. But in this case, I reused component in another page and I got this message.

I believe there's a simple historical reason why you can't enumerate over methods of built-in objects like Array for instance. Here's why:

Methods are properties of the prototype-object, say Object.prototype. That means that all Object-instances will inherit those methods. That's why you can use those methods on any object. Say .toString() for instance.

So IF methods were enumerable, and I would iterate over say {a:123} with: "for (key in {a:123}) {...}" what would happen? How many times would that loop be executed?

It would be iterated once for the single key 'a' in our example. BUT ALSO once for every enumerable property of Object.prototype. So if methods were enumerable (by default), then any loop over any object would loop over all its inherited methods as well.

pandas to the rescue:

import pandas as pd
print pd.read_csv('value.txt')

        Date    price  factor_1  factor_2
0  2012-06-11  1600.20     1.255     1.548
1  2012-06-12  1610.02     1.258     1.554
2  2012-06-13  1618.07     1.249     1.552
3  2012-06-14  1624.40     1.253     1.556
4  2012-06-15  1626.15     1.258     1.552
5  2012-06-16  1626.15     1.263     1.558
6  2012-06-17  1626.15     1.264     1.572

This returns pandas DataFrame that is similar to R's.

To compare local repository with remote one, simply use the below syntax:

git diff @{upstream}

EcmaScript 2017 added special functions to string prototype for that. padStart and padEnd are two new methods available in JavaScript string prototype object. As their name implies, they allow for formatting a string by adding padding characters at the start or the end. (Not supported by IE11 and lower)

var mystr = "Doe";
mystr = mystr.padStart('John ');

You can use a binding adapter(Kotlin) to achieve this. Create a binding adapter class named ChangeShapeColor like below

@BindingAdapter("shapeColor")

// Method to load shape and set its color 

fun loadShape(textView: TextView, color: String) {
// first get the drawable that you created for the shape 
val mDrawable = ContextCompat.getDrawable(textView.context, 
R.drawable.language_image_bg)
val  shape =   mDrawable as (GradientDrawable)
// use parse color method to parse #34444 to the int 
shape.setColor(Color.parseColor(color))
 }

Create a drawable shape in res/drawable folder. I have created a circle

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" >
<solid android:color="#anyColorCode"/>

<size
    android:width="@dimen/dp_16"
    android:height="@dimen/dp_16"/>
</shape>

Finally refer it to your view

  <TextView>
   .........
  app:shapeColor="@{modelName.colorString}"
 </Textview>

They are all logged under Elements in google chromes developer tools.

None of the above answers solved it for me.

I cant even find the 'libraries' folder in my xampp - ubuntu also.

So, I simply restarted using the following commands:

sudo service apache2 restart

and

sudo service mysql restart

• Just restarted apache and mysql. Logged in phpmyadmin again and it worked as usual.

Thanks me..!!

Padding will not work in Outlook. Instead of adding blank Image, you can simply use multiple spaces(& nbsp;) before elements/texts for padding left For padding top or bottom, you can add a div containing just spaces(& nbsp;) alone. This will work!!!

The default modifier is package. Only code in the same package will be able to invoke this constructor.

You want the CASE statement

WHERE OrderNumber LIKE
CASE WHEN IsNumeric(@OrderNumber)=1 THEN @OrderNumber ELSE '%' + @OrderNumber END

Here is the function for to check is String is Integer or not ?

public static boolean isStringInteger(String number ){
    try{
        Integer.parseInt(number);
    }catch(Exception e ){
        return false;
    }
    return true;
}

A way to mimic the margin on the row would be to use the pseudo selector to add some spacing on the td.

.highlight td::before, .highlight td::after
{
  content:"";
  height:10px;
  display:block;
}

This way anything marked with the highlight class will be separated top and bottom.

When running Wget with -r or -p, but without -N, -nd, or -nc, re-downloading a file will result in the new copy simply overwriting the old.

So adding -nc will prevent this behavior, instead causing the original version to be preserved and any newer copies on the server to be ignored.

You should use an android:weightSum attribute linear layout. Give linear layout a weightSum equal to the number of Buttons inside the layout, then set android:layout_weight="1" and set width of the button android:layout_width="0dp" further, you can style the layout using paddings and layout margins.

<LinearLayout android:id="@+id/LinearLayout01"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:gravity="center"
    android:weightSum="3">
    
    <Button
        android:id="@+id/btnOne"

        android:text="1"
        android:layout_height="wrap_content"
        android:width="120dip"
        android:layout_weight="1"
        android:layout_margin="15dp" 
        />
    
    <Button
        android:id="@+id/btnTwo"

It's not possible to clear user history without plugins. And also it's not an issue at developer's perspective, it's the burden of the user to clear his history.

Lets play trick with Boolean.compare(boolean, boolean). Default behavior of function: if both values are equal than it returns 0 otherwise -1.

public int valueOf(Boolean flag) {
   return Boolean.compare(flag, Boolean.TRUE) + 1;
}

Explanation: As we know default return of Boolean.compare is -1 in case of mis-match so +1 make return value to 0 for False and 1 for True

when you use \\b(\\w+)+\\b that means exact match with a word containing only word characters ([a-zA-Z0-9])

in your case for example setting \\b at the begining of regex will accept -12(with space) but again it won't accept -12(without space)

for reference to support my words: https://docs.oracle.com/javase/tutorial/essential/regex/bounds.html

Not exactly the most robust password protection here, so please don't use this to protect credit card numbers or something very important.

Simply drop all of the following code into a file called (secure.php), change the user and pass from "admin" to whatever you want. Then right under those lines where it says include("secure.html"), simply replace that with the filename you want them to be able to see.

They will access this page at [YouDomain.com/secure.php] and then the PHP script will internally include the file you want password protected so they won't know the name of that file, and can't later just access it directly bypassing the password prompt.

If you would like to add a further level of protection, I would recommend you take your (secure.html) file outside of your site's root folder [/public_html], and place it on the same level as that directory, so that it is not inside the directory. Then in the PHP script where you are including the file simply use ("../secure.html"). That (../) means go back a directory to find the file. Doing it this way, the only way someone can access the content that's on the (secure.html) page is through the (secure.php) script.

<?php
$user = $_POST['user'];
$pass = $_POST['pass'];

if($user == "admin"
&& $pass == "admin")
{
        include("secure.html");
}
else
{
    if(isset($_POST))
    {?>

            <form method="POST" action="secure.php">
            User <input type="text" name="user"></input><br/>
            Pass <input type="password" name="pass"></input><br/>
            <input type="submit" name="submit" value="Go"></input>
            </form>
    <?}
}
?>

I created a new AutomapperProfile class. It extends Profile. We have over 100 projects in our solution. Many projects have an AutomapperProfile class, but this one was new to this existing project. However, I did find what I had to do to fix this issue for us. There is a Binding project. Within the Initialization there is this code:

var mappingConfig = new List<Action<IConfiguration>>();

// Initialize the Automapper Configuration for all Known Assemblies
mappingConfig.AddRange( new List<Action<IConfiguration>>
{
   ConfigureProfilesInAssemblyOfType<Application.Administration.AutomapperProfile>,
   //...

I had to add ConfigureProfilesInAssemblyOfType<MyNewNamespace.AutomapperProfile>

Note that ConfigureProfilesInAssemblyOfType looks like this:

    private static void ConfigureProfilesInAssemblyOfType<T>( IConfiguration configuration )
    {
        var log = LogProvider.Get( typeof (AutomapperConfiguration) );

        // The Automapper Profile Type
        var automapperProfileType = typeof (Profile);

        // The Assembly containing the type
        var assembly = typeof (T).Assembly;
        log.Debug( "Scanning " + assembly.FullName );

        // Configure any Profile classes found in the assembly containing the type.
        assembly.GetTypes()
            .Where( automapperProfileType.IsAssignableFrom ).ToList()
            .ForEach( x =>
            {
                log.Debug( "Adding Profile '" + x.FullName + "'" );
                configuration.AddProfile( Activator.CreateInstance( x ) as Profile );
            } );
    }

I came here because I had the same problem.
What was the problem for me was that the procedure was defined in the package body, but not in the package header.
I was executing my function with a lose BEGIN END statement.

It means that the variable it is a prefix to is available to be used within a block.

I have different solution:

SELECT AUTO_INCREMENT - 1 as CurrentId FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'dbname' AND TABLE_NAME = 'tablename'

This can replace the MaxLength and the MinLength

[StringLength(40, MinimumLength = 10 , ErrorMessage = "Password cannot be longer than 40 characters and less than 10 characters")]

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

Here is the ES6 code which I use to create a directory (when it doesn't exist):

const fs = require('fs');
const path = require('path');

function createDirectory(directoryPath) {
  const directory = path.normalize(directoryPath);

  return new Promise((resolve, reject) => {
    fs.stat(directory, (error) => {
      if (error) {
        if (error.code === 'ENOENT') {
          fs.mkdir(directory, (error) => {
            if (error) {
              reject(error);
            } else {
              resolve(directory);
            }
          });
        } else {
          reject(error);
        }
      } else {
        resolve(directory);
      }
    });
  });
}

const directoryPath = `${__dirname}/test`;

createDirectory(directoryPath).then((path) => {
  console.log(`Successfully created directory: '${path}'`);
}).catch((error) => {
  console.log(`Problem creating directory: ${error.message}`)
});

Note:

• In the beginning of the createDirectory function, I normalize the path to guarantee that the path seperator type of the operating system will be used consistently (e.g. this will turn C:\directory/test into C:\directory\test (when being on Windows)
• fs.exists is deprecated, that's why I use fs.stat to check if the directory already exists
• If a directory doesn't exist, the error code will be ENOENT (Error NO ENTry)
• The directory itself will be created using fs.mkdir
• I prefer the asynchronous function fs.mkdir over it's blocking counterpart fs.mkdirSync and because of the wrapping Promise it will be guaranteed that the path of the directory will only be returned after the directory has been successfully created

From http://expressjs.com/api.html#cookieSession

To clear a cookie simply assign the session to null before responding:

req.session = null

There is a simpler way simply disable the error handler in your error handler if it does not match the error types you are doing and resume.

The handler below checks agains each error type and if none are a match it returns error resume to normal VBA ie GoTo 0 and resumes the code which then tries to rerun the code and the normal error block pops up.

On Error GoTo ErrorHandler

x = 1/0

ErrorHandler:
if Err.Number = 13 then ' 13 is Type mismatch (only used as an example)

'error handling code for this

end if

If err.Number = 1004 then ' 1004 is Too Large (only used as an example)

'error handling code for this

end if

On Error GoTo 0
Resume

You need to read and write document.cookie

if (document.cookie.indexOf("visited=") >= 0) {
  // They've been here before.
  alert("hello again");
}
else {
  // set a new cookie
  expiry = new Date();
  expiry.setTime(expiry.getTime()+(10*60*1000)); // Ten minutes

  // Date()'s toGMTSting() method will format the date correctly for a cookie
  document.cookie = "visited=yes; expires=" + expiry.toGMTString();
  alert("this is your first time");
}

// code to make the image round


import UIKit

extension UIImageView {
public func maskCircle(anyImage: UIImage) {


    self.contentMode = UIViewContentMode.ScaleAspectFill
    self.layer.cornerRadius = self.frame.height / 2
    self.layer.masksToBounds = false
    self.clipsToBounds = true




    // make square(* must to make circle),
    // resize(reduce the kilobyte) and
    // fix rotation.
    //        self.image = prepareImage(anyImage)
}
}

// to call the function from the view controller

self.imgCircleSmallImage.maskCircle(imgCircleSmallImage.image!)

You can also modify your config/routes.rb file like:

 get 'ajax/:action', to: 'ajax#:action', :defaults => { :format => 'json' }

Which will default the format to json. It is working fine for me in Rails 4.

Or if you want to go even further and you are using namespaces, you can cut down the duplicates:

namespace :api, defaults: {format: 'json'} do
   #your controller routes here ...
end

with the above everything under /api will be formatted as json by default.

Try this:

mongod --fork --logpath /var/log/mongodb.log

You may need to create the db-folder:

mkdir -p /data/db

If you get any 'Permission denied'-error, I'ld recommend changing the permissions of the particular files instead of running mongod as root.

This will work:

 >>>print(unicodedata.normalize('NFD', re.sub("[\(\[].*?[\)\]]", "", "bats\xc3\xa0")).encode('ascii', 'ignore'))

Output:

>>>bats

I have been using blockUI to avoid browser incompatibilies on disabled or hidden buttons.

http://malsup.com/jquery/block/#element

Then my buttons have a class autobutton:

  $(".autobutton").click(
     function(event) {
        var nv = $(this).html();
        var nv2 = '<span class="fa fa-circle-o-notch fa-spin" aria-hidden="true"></span> ' + nv;
        $(this).html(nv2);
        var form = $(this).parents('form:first');

        $(this).block({ message: null });
        form.submit();                
        });   

Then a form is like that:

<form>
....
<button class="autobutton">Submit</button>   
</form>

You could manually adjust the spacing using plt.subplots_adjust(top=0.85):

import numpy as np
import matplotlib.pyplot as plt

f = np.random.random(100)
g = np.random.random(100)
fig = plt.figure()
fig.suptitle('Long Suptitle', fontsize=24)
plt.subplot(121)
plt.plot(f)
plt.title('Very Long Title 1', fontsize=20)
plt.subplot(122)
plt.plot(g)
plt.title('Very Long Title 2', fontsize=20)
plt.subplots_adjust(top=0.85)
plt.show()

Here's a method I'm using.

public static <T> T initializeAndUnproxy(T entity) {
    if (entity == null) {
        throw new 
           NullPointerException("Entity passed for initialization is null");
    }

    Hibernate.initialize(entity);
    if (entity instanceof HibernateProxy) {
        entity = (T) ((HibernateProxy) entity).getHibernateLazyInitializer()
                .getImplementation();
    }
    return entity;
}

In my case, I had accidentally named a folder 'samples '. I couldn't see the space when I did 'ls -la'.

Eventually I realized this when I tried tabbing to autocomplete and saw 'samples\ /'.

To fix this I ran

mv samples\  samples

Solution 3

This is for using a single directory for multiple projects. I use this technique for some closely related projects where I often need to pull changes from one project into another. It's similar to the orphaned branches idea but the branches don't need to be orphaned. Simply start all the projects from the same empty directory state.

Start all projects from one committed empty directory

Don't expect wonders from this solution. As I see it, you are always going to have annoyances with untracked files. Git doesn't really have a clue what to do with them and so if there are intermediate files generated by a compiler and ignored by your .gitignore file, it is likely that they will be left hanging some of the time if you try rapidly swapping between - for example - your software project and a PH.D thesis project.

However here is the plan. Start as you ought to start any git projects, by committing the empty repository, and then start all your projects from the same empty directory state. That way you are certain that the two lots of files are fairly independent. Also, give your branches a proper name and don't lazily just use "master". Your projects need to be separate so give them appropriate names.

Git commits (and hence tags and branches) basically store the state of a directory and its subdirectories and Git has no idea whether these are parts of the same or different projects so really there is no problem for git storing different projects in the same repository. The problem is then for you clearing up the untracked files from one project when using another, or separating the projects later.

Create an empty repository

cd some_empty_directory
git init
touch .gitignore
git add .gitignore
git commit -m empty
git tag EMPTY

Start your projects from empty.

Work on one project.

git branch software EMPTY
git checkout software
echo "array board[8,8] of piece" > chess.prog

git add chess.prog 
git commit -m "chess program"

Start another project

whenever you like.

git branch thesis EMPTY
git checkout thesis
echo "the meaning of meaning" > philosophy_doctorate.txt
git add philosophy_doctorate.txt 
git commit -m "Ph.D"

Switch back and forth

Go back and forwards between projects whenever you like. This example goes back to the chess software project.

git checkout software
echo "while not end_of_game do make_move()" >> chess.prog
git add chess.prog 
git commit -m "improved chess program"

Untracked files are annoying

You will however be annoyed by untracked files when swapping between projects/branches.

touch untracked_software_file.prog
git checkout thesis 
ls
    philosophy_doctorate.txt  untracked_software_file.prog

It's not an insurmountable problem

Sort of by definition, git doesn't really know what to do with untracked files and it's up to you to deal with them. You can stop untracked files from being carried around from one branch to another as follows.

git checkout EMPTY 
ls
    untracked_software_file.prog
rm -r *
    (directory is now really empty, apart from the repository stuff!)
git checkout thesis
ls
    philosophy_doctorate.txt

By ensuring that the directory was empty before checking out our new project we made sure there were no hanging untracked files from another project.

A refinement

$ GIT_AUTHOR_DATE='2001-01-01:T01:01:01' GIT_COMMITTER_DATE='2001-01-01T01:01:01' git commit -m empty

If the same dates are specified whenever committing an empty repository, then independently created empty repository commits can have the same SHA1 code. This allows two repositories to be created independently and then merged together into a single tree with a common root in one repository later.

Example

# Create thesis repository. 
# Merge existing chess repository branch into it

mkdir single_repo_for_thesis_and_chess
cd single_repo_for_thesis_and_chess
git init
touch .gitignore
git add .gitignore
GIT_AUTHOR_DATE='2001-01-01:T01:01:01' GIT_COMMITTER_DATE='2001-01-01:T01:01:01' git commit -m empty
git tag EMPTY
echo "the meaning of meaning" > thesis.txt
git add thesis.txt
git commit -m "Wrote my PH.D"
git branch -m master thesis

# It's as simple as this ...
git remote add chess ../chessrepository/.git
git fetch chess chess:chess

Result

Use subdirectories per project?

It may also help if you keep your projects in subdirectories where possible, e.g. instead of having files

chess.prog
philosophy_doctorate.txt 

have

chess/chess.prog
thesis/philosophy_doctorate.txt 

In this case your untracked software file will be chess/untracked_software_file.prog. When working in the thesis directory you should not be disturbed by untracked chess program files, and you may find occasions when you can work happily without deleting untracked files from other projects.

Also, if you want to remove untracked files from other projects, it will be quicker (and less prone to error) to dump an unwanted directory than to remove unwanted files by selecting each of them.

Branch names can include '/' characters

So you might want to name your branches something like

project1/master
project1/featureABC
project2/master
project2/featureXYZ

For me in IntelliJ it was showing me a popup to import the existing project as gradle project. I just clicked ok on it and then the folder structure appeared properly.

According to RFC 4329 the correct MIME type for JavaScript should be application/javascript. Howerver, older IE versions choke on this since they expect text/javascript.

Use the split function.

static void Main(string[] args)
{
    string s = "223232-1.jpg";
    Console.WriteLine(s.Split('-')[0]);
    s = "443-2.jpg";
    Console.WriteLine(s.Split('-')[0]);
    s = "34443553-5.jpg";
    Console.WriteLine(s.Split('-')[0]);

Console.ReadKey();
}

If your string doesn't have a - then you'll get the whole string.

&& it's operation return true only if both operand it's true which implies

}

|| it's operation return true if one or both operand it's true which implies

I use environment for that. It works automatically and you don't have to create new injectable service and most usefull for me, don't need to import via constructor.

1) Create environment variable in your environment.ts

export const environment = {
    ...
    // runtime variables
    isContentLoading: false,
    isDeployNeeded: false
}

2) Import environment.ts in *.ts file and create public variable (i.e. "env") to be able to use in html template

import { environment } from 'environments/environment';

@Component(...)
export class TestComponent {
    ...
    env = environment;
}

3) Use it in template...

<app-spinner *ngIf='env.isContentLoading'></app-spinner>

in *.ts ...

env.isContentLoading = false 

(or just environment.isContentLoading in case you don't need it for template)

You can create your own set of globals within environment.ts like so:

export const globals = {
    isContentLoading: false,
    isDeployNeeded: false
}

and import directly these variables (y)

In SQL Server 2012 and above, you don't need to create a link. You can execute directly

SELECT * FROM [TARGET_DATABASE].dbo.[TABLE] AS _TARGET

I don't know whether previous versions of SQL Server work as well

You can set the hours, minutes, seconds and microseconds to whatever you like

datetime.datetime.today().replace(hour=0, minute=0, second=0, microsecond=0)

but trutheality's answer is probably best when they are all to be zero and you can just compare the .date()s of the times

Maybe it is faster though if you have to compare hundreds of datetimes because you only need to do the replace() once vs hundreds of calls to date()

To take care of your extension issue, how about:

string formatString = "###-###-#### ####";
returnValue = Convert.ToInt64(phoneNumber)
                     .ToString(formatString.Substring(0,phoneNumber.Length+3))
                     .Trim();

In your example number is a primitive, so will be stored as a value.

If you want to use a reference then you should use one of the wrapper types (e.g. Integer)

Use following to call function of a frame in parent page

parent.document.getElementById('frameid').contentWindow.somefunction()

exec is for statement and does not return anything. eval is for expression and returns value of expression.

expression means "something" while statement means "do something".

A very simple bash one liner that keeps the original extensions, adds leading zeros, and also works in OSX:

num=0; for i in *; do mv "$i" "$(printf '%04d' $num).${i#*.}"; ((num++)); done

You can use JSON.stringify(object) with an object and I just wrote a function that'll recursively convert an array to an object, like this JSON.stringify(convArrToObj(array)), which is the following code (more detail can be found on this answer):

// Convert array to object
var convArrToObj = function(array){
    var thisEleObj = new Object();
    if(typeof array == "object"){
        for(var i in array){
            var thisEle = convArrToObj(array[i]);
            thisEleObj[i] = thisEle;
        }
    }else {
        thisEleObj = array;
    }
    return thisEleObj;
}

To make it more generic, you can override the JSON.stringify function and you won't have to worry about it again, to do this, just paste this at the top of your page:

// Modify JSON.stringify to allow recursive and single-level arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        return oldJSONStringify(convArrToObj(input));
    };
})();

And now JSON.stringify will accept arrays or objects! (link to jsFiddle with example)

Edit:

Here's another version that's a tad bit more efficient, although it may or may not be less reliable (not sure -- it depends on if JSON.stringify(array) always returns [], which I don't see much reason why it wouldn't, so this function should be better as it does a little less work when you use JSON.stringify with an object):

(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

Excerpt from PostgreSQL documentation:

Restricting and cascading deletes are the two most common options. [...] CASCADE specifies that when a referenced row is deleted, row(s) referencing it should be automatically deleted as well.

This means that if you delete a category – referenced by books – the referencing book will also be deleted by ON DELETE CASCADE.

Example:

CREATE SCHEMA shire;

CREATE TABLE shire.clans (
    id serial PRIMARY KEY,
    clan varchar
);

CREATE TABLE shire.hobbits (
    id serial PRIMARY KEY,
    hobbit varchar,
    clan_id integer REFERENCES shire.clans (id) ON DELETE CASCADE
);

DELETE FROM clans will CASCADE to hobbits by REFERENCES.

sauron@mordor> psql
sauron=# SELECT * FROM shire.clans;
 id |    clan    
----+------------
  1 | Baggins
  2 | Gamgi
(2 rows)

sauron=# SELECT * FROM shire.hobbits;
 id |  hobbit  | clan_id 
----+----------+---------
  1 | Bilbo    |       1
  2 | Frodo    |       1
  3 | Samwise  |       2
(3 rows)

sauron=# DELETE FROM shire.clans WHERE id = 1 RETURNING *;
 id |  clan   
----+---------
  1 | Baggins
(1 row)

DELETE 1
sauron=# SELECT * FROM shire.hobbits;
 id |  hobbit  | clan_id 
----+----------+---------
  3 | Samwise  |       2
(1 row)

If you really need the opposite (checked by the database), you will have to write a trigger!

when you do UNIQUE as a table level constraint as you have done then what your defining is a bit like a composite primary key see ddl constraints, here is an extract

"This specifies that the *combination* of values in the indicated columns is unique across the whole table, though any one of the columns need not be (and ordinarily isn't) unique."

this means that either field could possibly have a non unique value provided the combination is unique and this does not match your foreign key constraint.

most likely you want the constraint to be at column level. so rather then define them as table level constraints, 'append' UNIQUE to the end of the column definition like name VARCHAR(60) NOT NULL UNIQUE or specify indivdual table level constraints for each field.

My /var/log/apache2 folder was 35g and some logs in /var/log totaled to be the other 5g of my 40g hard drive. I cleared out all the *.gz logs and after making sure the other logs werent going to do bad things if I messed with them, i just cleared them too.

echo "clear" > access.log

etc.

df.write.mode('overwrite').parquet("/output/folder/path") works if you want to overwrite a parquet file using python. This is in spark 1.6.2. API may be different in later versions

For all the good answers above, I'm just going to give a concrete example in Java servlet HttpSession class. Hope this example helps to clarify some question you may still have.

If you need to store and retrieve values for a session, you use setAttribute(String, Object), and getAttribute(String, Object) method. So for a boolean value, you are forced to use the Boolean class if you want to store it in an http session.

HttpSession sess = request.getSession(false);
Boolean isAdmin = (Boolean) sess.getAttribute("admin");
if (! isAdmin) ...

The last line will cause a NullPointerException if the attribute values is not set. (which is the reason led me to this post). So the 3 logic state is here to stay, whether you prefer to use it or not.

R uses functions for implementing try-catch block:

The syntax somewhat looks like this:

result = tryCatch({
    expr
}, warning = function(warning_condition) {
    warning-handler-code
}, error = function(error_condition) {
    error-handler-code
}, finally={
    cleanup-code
})

In tryCatch() there are two ‘conditions’ that can be handled: ‘warnings’ and ‘errors’. The important thing to understand when writing each block of code is the state of execution and the scope. @source

Change your markup slightly:

    $("input.group1").removeAttr("disabled");_x000D_
  } else {_x000D_
    $("input.group1").attr("disabled", true);_x000D_

  <input type="checkbox" name="chk9[150]" class="group1"><br>_x000D_
</form>

You can do this using attribute selectors without introducing the ID and classes but it's slower and (imho) harder to read.

Consider a restaurant. The creation of "today's meal" is a factory pattern, because you tell the kitchen "get me today's meal" and the kitchen (factory) decides what object to generate, based on hidden criteria.

The builder appears if you order a custom pizza. In this case, the waiter tells the chef (builder) "I need a pizza; add cheese, onions and bacon to it!" Thus, the builder exposes the attributes the generated object should have, but hides how to set them.

When you specify -jar then the -cp parameter will be ignored.

From the documentation:

When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored.

You also cannot "include" needed jar files into another jar file (you would need to extract their contents and put the .class files into your jar file)

You have two options:

1. include all jar files from the lib directory into the manifest (you can use relative paths there)
2. Specify everything (including your jar) on the commandline using -cp:
   java -cp MyJar.jar:lib/* com.somepackage.subpackage.Main

There is a jquery plugin for this. It scrolls document to a specific element, so that it would be perfectly in the middle of viewport. It also supports animation easings so that the scroll effect would look super smooth. Check out AnimatedScroll.js.

SELECT COUNT(ID) FROM tblA a
WHERE a.ID NOT IN (SELECT b.ID FROM tblB b)    --For count


SELECT ID FROM tblA a
WHERE a.ID NOT IN (SELECT b.ID FROM tblB b)    --For results

In addition to the answers above, you can check the type of object using type(plt.subplots()) which returns a tuple, on the other hand, type(plt.subplot()) returns matplotlib.axes._subplots.AxesSubplot which you can't unpack.

While the other answers will do the job fine for most people, the "correct" Unix way of doing this should be mentioned. Since all types of text terminals do not support these sequences, you can query the terminfo database, an abstraction over the capabilites of various text terminals. This might seem mostly of historical interest – software terminals in use today generally support the ANSI sequences – but it does have (at least) one practical effect: it is sometimes useful to be able to set the environment variable TERM to dumb to avoid all such styling, for example when saving the output to a text file. Also, it feels good to do things right. :-)

You can use the ruby-terminfo gem. It needs some C compiling to install; I was able to install it under my Ubuntu 14.10 system with:

$ sudo apt-get install libncurses5-dev
$ gem install ruby-terminfo --user-install

Then you can query the database like this (see the terminfo man page for a list of what codes are available):

require 'terminfo' 
TermInfo.control("bold")
puts "Bold text"
TermInfo.control("sgr0")
puts "Back to normal."
puts "And now some " + TermInfo.control_string("setaf", 1) + 
     "red" + TermInfo.control_string("sgr0") + " text."

Here's a little wrapper class I put together to make things a little more simple to use.

require 'terminfo'

class Style
  def self.style() 
    @@singleton ||= Style.new
  end

  colors = %w{black red green yellow blue magenta cyan white}
  colors.each_with_index do |color, index|
    define_method(color) { get("setaf", index) }
    define_method("bg_" + color) { get("setab", index) }
  end

  def bold()  get("bold")  end
  def under() get("smul")  end
  def dim()   get("dim")   end
  def clear() get("sgr0")  end

  def get(*args)
    begin
      TermInfo.control_string(*args)
    rescue TermInfo::TermInfoError
      ""
    end
  end
end

Usage:

c = Style.style
C = c.clear
puts "#{c.red}Warning:#{C} this is #{c.bold}way#{C} #{c.bg_red}too much #{c.cyan + c.under}styling#{C}!"
puts "#{c.dim}(Don't you think?)#{C}"

(edit) Finally, if you'd rather not require a gem, you can rely on the tput program, as described here – Ruby example:

puts "Hi! " + `tput setaf 1` + "This is red!" + `tput sgr0`

 //if you want to get parameter from url use:
 parse_str($_SERVER['QUERY_STRING'], $_GET);
 //then you can use:
 if(isset($_GET["par"])){
      echo $_GET["par"];
 }
 //if you want to get current page url use:
 $current_url = current_url();

You don't need an external library for this. The below code works for LINQ to SQL/entities.

    /// <summary>
    /// Sorts the elements of a sequence according to a key and the sort order.

    /// <returns>An <see cref="T:System.Linq.IOrderedQueryable`1" /> whose elements are sorted according to a key and sort order.</returns>
    public static IQueryable<TSource> OrderBy<TSource>(this IQueryable<TSource> query, string key, bool ascending = true)
    {
        if (string.IsNullOrWhiteSpace(key))
        {
            return query;
        }

        var lambda = (dynamic)CreateExpression(typeof(TSource), key);

        return ascending 
            ? Queryable.OrderBy(query, lambda) 
            : Queryable.OrderByDescending(query, lambda);
    }

    private static LambdaExpression CreateExpression(Type type, string propertyName)
    {
        var param = Expression.Parameter(type, "x");

        Expression body = param;
        foreach (var member in propertyName.Split('.'))
        {
            body = Expression.PropertyOrField(body, member);
        }

        return Expression.Lambda(body, param);
    }

Here's a script I used to batch import a bunch of crt files in the current directory into the java keystore. Just save this to the same folder as your certificate, and run it like so:

./import_all_certs.sh

import_all_certs.sh

KEYSTORE="$(/usr/libexec/java_home)/jre/lib/security/cacerts";

function running_as_root()
{
  if [ "$EUID" -ne 0 ]
    then echo "NO"
    exit
  fi

  echo "YES"
}

function import_certs_to_java_keystore
{
  for crt in *.crt; do 
    echo prepping $crt 
    keytool -import -file $crt -storepass changeit -noprompt --alias alias__${crt} -keystore $KEYSTORE
    echo 
  done
}

if [ "$(running_as_root)" == "YES" ]
then
  import_certs_to_java_keystore
else
  echo "This script needs to be run as root!"
fi

JavaScript's dates can be compared using the same comparison operators the rest of the data types use: >, <, <=, >=, ==, !=, ===, !==.

If you have two dates A and B, then A < B if A is further back into the past than B.

But it sounds like what you're having trouble with is turning a string into a date. You do that by simply passing the string as an argument for a new Date:

var someDate = new Date("12/03/2008");

or, if the string you want is the value of a form field, as it seems it might be:

var someDate = new Date(document.form1.Textbox2.value);

Should that string not be something that JavaScript recognizes as a date, you will still get a Date object, but it will be "invalid". Any comparison with another date will return false. When converted to a string it will become "Invalid Date". Its getTime() function will return NaN, and calling isNaN() on the date itself will return true; that's the easy way to check if a string is a valid date.

As already mentioned you can use Fine Code Coverage that visualize coverlet output. If you create a xunit test project (dotnet new xunit) you'll find coverlet reference already present in csproj file because Coverlet is the default coverage tool for every .NET Core and >= .NET 5 applications.

Microsoft has an example using ReportGenerator that converts coverage reports generated by coverlet, OpenCover, dotCover, Visual Studio, NCover, Cobertura, JaCoCo, Clover, gcov or lcov into human readable reports in various formats.

Example report:

While the article focuses on C# and xUnit as the test framework, both MSTest and NUnit would also work.

Guide:

https://docs.microsoft.com/en-us/dotnet/core/testing/unit-testing-code-coverage?tabs=windows#generate-reports

If you want code coverage in .xml files you can run any of these commands:

dotnet test --collect:"XPlat Code Coverage"

dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura

Set the timeout parameter:

r = requests.get(w, verify=False, timeout=10) # 10 seconds

As long as you don't set stream=True on that request, this will cause the call to requests.get() to timeout if the connection takes more than ten seconds, or if the server doesn't send data for more than ten seconds.

You can manual disable ssl verfiy, and try again. :)

git config --global http.sslverify false

You can do

current_user.methods

For better listing

puts "\n\current_user.methods : "+ current_user.methods.sort.join("\n").to_s+"\n\n"

Option 1:

You can set CMake variables at command line like this:

cmake -D CMAKE_C_COMPILER="/path/to/your/c/compiler/executable" -D CMAKE_CXX_COMPILER "/path/to/your/cpp/compiler/executable" /path/to/directory/containing/CMakeLists.txt

See this to learn how to create a CMake cache entry.

Option 2:

In your shell script build_ios.sh you can set environment variables CC and CXX to point to your C and C++ compiler executable respectively, example:

export CC=/path/to/your/c/compiler/executable
export CXX=/path/to/your/cpp/compiler/executable
cmake /path/to/directory/containing/CMakeLists.txt

Option 3:

Edit the CMakeLists.txt file of "Assimp": Add these lines at the top (must be added before you use project() or enable_language() command)

set(CMAKE_C_COMPILER "/path/to/your/c/compiler/executable")
set(CMAKE_CXX_COMPILER "/path/to/your/cpp/compiler/executable")

See this to learn how to use set command in CMake. Also this is a useful resource for understanding use of some of the common CMake variables.

Sadly, many JSON C++ libraries have APIs that are non trivial to use, while JSON was intended to be easy to use.

So I tried jsoncpp from the gSOAP tools on the JSON doc shown in one of the answers above and this is the code generated with jsoncpp to construct a JSON object in C++ which is then written in JSON format to std::cout:

value x(ctx);
x["appDesc"]["description"] = "SomeDescription";
x["appDesc"]["message"] = "SomeMessage";
x["appName"]["description"] = "Home";
x["appName"]["message"] = "Welcome";
x["appName"]["imp"][0] = "awesome";
x["appName"]["imp"][1] = "best";
x["appName"]["imp"][2] = "good";
std::cout << x << std::endl;

and this is the code generated by jsoncpp to parse JSON from std::cin and extract its values (replace USE_VAL as needed):

value x(ctx);
std::cin >> x;
if (x.soap->error)
  exit(EXIT_FAILURE); // error parsing JSON
#define USE_VAL(path, val) std::cout << path << " = " << val << std::endl
if (x.has("appDesc"))
{
  if (x["appDesc"].has("description"))
    USE_VAL("$.appDesc.description", x["appDesc"]["description"]);
  if (x["appDesc"].has("message"))
    USE_VAL("$.appDesc.message", x["appDesc"]["message"]);
}
if (x.has("appName"))
{
  if (x["appName"].has("description"))
    USE_VAL("$.appName.description", x["appName"]["description"]);
  if (x["appName"].has("message"))
    USE_VAL("$.appName.message", x["appName"]["message"]);
  if (x["appName"].has("imp"))
  {
    for (int i2 = 0; i2 < x["appName"]["imp"].size(); i2++)
      USE_VAL("$.appName.imp[]", x["appName"]["imp"][i2]);
  }
}

This code uses the JSON C++ API of gSOAP 2.8.28. I don't expect people to change libraries, but I think this comparison helps to put JSON C++ libraries in perspective.

Json has to have key-value pairs. Tho you can still have an array as the value part. Thus add a "key" of your chousing:

var json = JSON.stringify({whatver: test});

Much too late, but here is a method that works during gdb session.

gdb <executable>

then

(gdb) apropos argument

This will return lots of matches, the useful one is set args.

set args -- Set argument list to give program being debugged when it is started.

set args arg1 arg2 ...

then

r

This will run the program, passing to main(argc, argv) the arguments and the argument count.

• For XHTML, <input type="text" disabled="disabled" /> is the valid markup.
• For HTML5, <input type="text" disabled /> is valid and used by W3C on their samples.
• In fact, both ways works on all major browsers.

If generators are available it becomes even more easier:

var query = {'username':this.req.user.username};
this.req.newData.username = this.req.user.username;
this.body = yield MyModel.findOneAndUpdate(query, this.req.newData).exec();

On the Mac version I was getting the error when trying to run JSON-Clojure.json.clj, which is the script to export a database table to JSON. To get it to work I had to download the latest Clojure JAR from http://clojure.org/ and then right-click on PHPStorm app in the Finder and "Show Package Contents". Then go to Contents in there. Then open the lib folder, and see a bunch of .jar files. Copy the clojure-1.8.0.jar file from the unzipped archive I downloaded from clojure.org into the aforementioned lib folder inside the PHPStorm.app/Contents/lib. Restart the app. Now it freaking works.

EDIT: You also have to put the JSR-223 script engine into PHPStorm.app/Contents/lib. It can be built from https://github.com/ato/clojure-jsr223 or downloaded from https://www.dropbox.com/s/jg7s0c41t5ceu7o/clojure-jsr223-1.5.1.jar?dl=0 .

In Angular 8 you should do like this.router.events.subscribe((event: Event) => {})

Example:

import { Component } from '@angular/core'; 
import { Router, Event } from '@angular/router';
import { NavigationStart, NavigationError, NavigationEnd } from '@angular/router';

@Component({
    selector: 'app-root',
    template: `<router-outlet></router-outlet>`
})
export class AppComponent {

    constructor(private router: Router) {
        //Router subscriber
        this.router.events.subscribe((event: Event) => {
            if (event instanceof NavigationStart) {
                //do something on start activity
            }

            if (event instanceof NavigationError) {
                // Handle error
                console.error(event.error);
            }

            if (event instanceof NavigationEnd) {
                //do something on end activity
            }
        });
   }
}

Check Java versions That was a problem for me. IDE (Intellij in my case) could launch without the problem, but when I tried to run war inside tomcat docker image app didn't work. The reason was docker image had a different (lower) version compare to the development environment. There were no errors messages indicating any of this.

In your situation I think your partner is correct. What's nice about rebasing is that to the outsider your changes look like they all happened in a clean sequence all by themselves. This means

• your changes are very easy to review
• you can continue to make nice, small commits and yet you can make sets of those commits public (by merging into master) all at once
• when you look at the public master branch you'll see different series of commits for different features by different developers but they won't all be intermixed

You can still continue to push your private development branch to the remote repository for the sake of backup but others should not treat that as a "public" branch since you'll be rebasing. BTW, an easy command for doing this is git push --mirror origin .

The article Packaging software using Git does a fairly nice job explaining the trade offs in merging versus rebasing. It's a little different context but the principals are the same -- it basically comes down to whether your branches are public or private and how you plan to integrate them into the mainline.

You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:

• full path from file input using jquery
• How to get the file path from HTML input form in Firefox 3

In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file" field, ostensibly for backward compatibility reasons.

• http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-March/018981.html
• The Mystery of c:\fakepath Unveiled

So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.

This is too late but posting my experience for people looking at it later:-

In MS VS 2010 I had the same issue. It got resolved by putting quotes to post build copy command args which contained spaces!

In Project Properties --> Configuration Properties --> Build Events --> Post-Build Event --> Command Line change:

copy $(ProjectDir)a\b\c $(OutputPath)

to

copy "$(ProjectDir)a\b\c" "$(OutputPath)"

I had similar issue. I updated android studio build tools and my project didn't find "android-22". I looked in android sdk manager and it was installed.

To fix this issue I uninstalled "android-22" and installed again.

You can try this:

print "'%-100s'" % 'hi'

The resolution of DateTime.Now depends on your system timer (~10ms on a current Windows OS)...so it's giving the same ending value there (it doesn't count any more finite than that).

I find that using the shortcuts for building/cleaning and running your project really saved me some time:

• Cmd-R: Build & Run
• Cmd-Y: Build & Debug
• Cmd-Shift-Enter: Stop running project
• Cmd-Shift-K: Clean build

Cast the dtype of the col to str and you can perform vectorised slicing calling str:

if you need to you can cast the dtype back again calling astype(int) on the column

If you don't need the unique identifier for further styling of the divs and are using HTML5 you could try and go with custom Data Attributes. Read on here or try a google search for HTML5 Custom Data Attributes

Using another trait:

trait ATrait {
    function calc($v) {
        return $v+1;
    }
}

class A {
    use ATrait;
}

trait BTrait {
    function calc($v) {
        $v++;
        return parent::calc($v);
    }
}

class B extends A {
    use BTrait;
}

print (new B())->calc(2); // should print 4

Another thing to check:

When you install the GoogleAPIs into a .Net app with NuGet, it will inject a new set of dummy values in your *.config file.

Check that any original values are still in place, and remove dummy entries.

Everyone's answers are great, but here's one I think is a bit more comprehensive...

This is written for javascript match use of a single number in a single line:

^(?!.*911.*\d{4})((\+?1[\/ ]?)?(?![\(\. -]?555.*)\( ?[2-9][0-9]{2} ?\) ?|(\+?1[\.\/ -])?[2-9][0-9]{2}[\.\/ -]?)(?!555.?01..)([2-9][0-9]{2})[\.\/ -]?([0-9]{4})$

If you want to match at word boundaries, just change the ^ and $ to \b

I welcome any suggestions, corrections, or criticisms of this solution. As far as I can tell, this matches the NANP format (for USA numbers - I didn't validate other North American countries when creating this), avoids any 911 errors (can't be in the area code or region code), eliminates only those 555 numbers which are actually invalid (region code of 555 followed by 01xx where x = any number).

You could try using something like:

sed -n 's/$/:80/' ips.txt > new-ips.txt

Provided that your file format is just as you have described in your question.

The s/// substitution command matches (finds) the end of each line in your file (using the $ character) and then appends (replaces) the :80 to the end of each line. The ips.txt file is your input file... and new-ips.txt is your newly-created file (the final result of your changes.)

Also, if you have a list of IP numbers that happen to have port numbers attached already, (as noted by Vlad and as given by aragaer,) you could try using something like:

sed '/:[0-9]*$/ ! s/$/:80/' ips.txt > new-ips.txt

So, for example, if your input file looked something like this (note the :80):

127.0.0.1
128.0.0.0:80
121.121.33.111

The final result would look something like this:

127.0.0.1:80
128.0.0.0:80
121.121.33.111:80

I had the same problem some time ago and was disappointed because I couldn't find any solution that suites my needs so I wrote my own class. Honestly, I did found some code back then, but even that wasn't what I was searching for so I adapted it and now I'm sharing it, just like the author of that piece of code did.

EDIT: This is the original (although slightly different) code: CircularArrayList for java

I don't have the link of the source because it was time ago, but here's the code:

import java.util.AbstractList;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.RandomAccess;

public class CircularArrayList<E> extends AbstractList<E> implements RandomAccess {

private final int n; // buffer length
private final List<E> buf; // a List implementing RandomAccess
private int leader = 0;
private int size = 0;


public CircularArrayList(int capacity) {
    n = capacity + 1;
    buf = new ArrayList<E>(Collections.nCopies(n, (E) null));
}

public int capacity() {
    return n - 1;
}

private int wrapIndex(int i) {
    int m = i % n;
    if (m < 0) { // modulus can be negative
        m += n;
    }
    return m;
}

@Override
public int size() {
    return this.size;
}

@Override
public E get(int i) {
    if (i < 0 || i >= n-1) throw new IndexOutOfBoundsException();

    if(i > size()) throw new NullPointerException("Index is greater than size.");

    return buf.get(wrapIndex(leader + i));
}

@Override
public E set(int i, E e) {
    if (i < 0 || i >= n-1) {
        throw new IndexOutOfBoundsException();
    }
    if(i == size()) // assume leader's position as invalid (should use insert(e))
        throw new IndexOutOfBoundsException("The size of the list is " + size() + " while the index was " + i
                +". Please use insert(e) method to fill the list.");
    return buf.set(wrapIndex(leader - size + i), e);
}

public void insert(E e)
{
    int s = size();     
    buf.set(wrapIndex(leader), e);
    leader = wrapIndex(++leader);
    buf.set(leader, null);
    if(s == n-1)
        return; // we have replaced the eldest element.
    this.size++;

}

@Override
public void clear()
{
    int cnt = wrapIndex(leader-size());
    for(; cnt != leader; cnt = wrapIndex(++cnt))
        this.buf.set(cnt, null);
    this.size = 0;      
}

public E removeOldest() {
    int i = wrapIndex(leader+1);

    for(;;i = wrapIndex(++i)) {
        if(buf.get(i) != null) break;
        if(i == leader)
            throw new IllegalStateException("Cannot remove element."
                    + " CircularArrayList is empty.");
    }

    this.size--;
    return buf.set(i, null);
}

@Override
public String toString()
{
    int i = wrapIndex(leader - size());
    StringBuilder str = new StringBuilder(size());

    for(; i != leader; i = wrapIndex(++i)){
        str.append(buf.get(i));
    }
    return str.toString();
}

public E getOldest(){
    int i = wrapIndex(leader+1);

    for(;;i = wrapIndex(++i)) {
        if(buf.get(i) != null) break;
        if(i == leader)
            throw new IllegalStateException("Cannot remove element."
                    + " CircularArrayList is empty.");
    }

    return buf.get(i);
}

public E getNewest(){
    int i = wrapIndex(leader-1);
    if(buf.get(i) == null)
        throw new IndexOutOfBoundsException("Error while retrieving the newest element. The Circular Array list is empty.");
    return buf.get(i);
}
}

WARNING: git clean -f will remove untracked files, meaning they're gone for good since they aren't stored in the repository. Make sure you really want to remove all untracked files before doing this.

Try this and see git clean -f.

git reset --hard will not remove untracked files, where as git-clean will remove any files from the tracked root directory that are not under Git tracking.

Alternatively, as @Paul Betts said, you can do this (beware though - that removes all ignored files too)

• git clean -df
• git clean -xdf CAUTION! This will also delete ignored files

On Windows 7 with Firefox 10, the cert8.db file is stored at %userprofile%\AppData\Roaming\Mozilla\Firefox\Profiles\########.default\cert8.db. If you are an administrator, you can probably write a simple WMI application to copy the file to the User's respective folder.

Also, a solution that worked for me from http://www.appdeploy.com/messageboards/tm.asp?m=52532&mpage=1&key=&#52532

1. Copied CERTUTIL.EXE from the NSS zip file ( http://www.mozilla.org/projects/security/pki/nss/tools/ ) to C:\Temp\CertImport (I also placed the certificates I want to import there)

2. Copied all the dll's from the NSS zip file to C\:Windows\System32

3. Created a BAT file in %Appdata%\mozilla\firefox\profiles with this script...

   Set FFProfdir=%Appdata%\mozilla\firefox\profiles 
   Set CERTDIR=C:\Temp\CertImport 
   DIR /A:D /B > "%Temp%\FFProfile.txt" 
   FOR /F "tokens=*" %%i in (%Temp%\FFProfile.txt) do ( 
   CD /d "%FFProfDir%\%%i" 
   COPY cert8.db cert8.db.orig /y 
   For %%x in ("%CertDir%\Cert1.crt") do "%Certdir%\certutil.exe" -A -n "Cert1" -i "%%x" -t "TCu,TCu,TCu" -d . 
   For %%x in ("%CertDir%\Cert2.crt") do "%Certdir%\certutil.exe" -A -n "Cert2" -i "%%x" -t "TCu,TCu,TCu" -d . 
   ) 
   DEL /f /q "%Temp%\FFProfile.txt" 
   

4. Executed the BAT file with good results.

Fairly late to this party, but I came across this issue myself today at work. Here is how I solved the issue.

I was accessing a 3rd party API to retrieve a list of books. The object returned a massive JSON object containing roughly 20+ fields, of which I only needed the ID as a List string object. I used linq on the dynamic object to retrieve the specific field I needed and then inserted it into my List string object.

dynamic content = JsonConvert.DeserializeObject(requestContent);
var contentCodes = ((IEnumerable<dynamic>)content).Where(p => p._id != null).Select(p=>p._id).ToList();

List<string> codes = new List<string>();

foreach (var code in contentCodes)
{
    codes.Add(code?.ToString());
}

This is one solution. If you want to make it more generic, you can use the StringUtils library.

String value = "{first_name = naresh,last_name = kumar,gender = male}";
value = value.substring(1, value.length()-1);           //remove curly brackets
String[] keyValuePairs = value.split(",");              //split the string to creat key-value pairs
Map<String,String> map = new HashMap<>();               

for(String pair : keyValuePairs)                        //iterate over the pairs
{
    String[] entry = pair.split("=");                   //split the pairs to get key and value 
    map.put(entry[0].trim(), entry[1].trim());          //add them to the hashmap and trim whitespaces
}

For example you can switch

 value = value.substring(1, value.length()-1);

to

 value = StringUtils.substringBetween(value, "{", "}");

if you are using StringUtils which is contained in apache.commons.lang package.

Above method is working, but here are more realistic slide up and slide down animations from the top of the screen.

Just create these two animations under the anim folder

slide_down.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="200"
        android:fromYDelta="-100%"
        android:toYDelta="0" />
</set> 

slide_up.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="200"
        android:fromYDelta="0"
        android:toYDelta="-100%" />
</set>

Load animation in java class like this

imageView.startAnimation(AnimationUtils.loadAnimation(getContext(),R.anim.slide_up));
imageView.startAnimation(AnimationUtils.loadAnimation(getContext(),R.anim.slide_down));

You can access characters in strings in the same way as you would access an array index, e.g.

$length = strlen($string);
$thisWordCodeVerdeeld = array();
for ($i=0; $i<$length; $i++) {
    $thisWordCodeVerdeeld[$i] = $string[$i];
}

You could also do:

$thisWordCodeVerdeeld = str_split($string);

However you might find it is easier to validate the string as a whole string, e.g. using regular expressions.

I did it by using the following options:

/njh /njs /ndl /nc /ns

Note that the file name still displays, but that's fine for me.

For more information on robocopy, go to http://technet.microsoft.com/en-us/library/cc733145%28WS.10%29.aspx

You can actually just use

$("#form").attr("target", "NewAction");

As far as I know, this will NOT fail silently.

If the page is opening in a new target, you may need to make sure the URL is unique each time because Webkit (chrome/safari) will cache the fact you have visited that URL and won't perform the post.

For example

$("form").attr("action", "/Pages/GeneratePreview?" + new Date().getMilliseconds());

I've pushed django-pdb to PyPI. It's a simple app that means you don't need to edit your source code every time you want to break into pdb.

Installation is just...

1. pip install django-pdb
2. Add 'django_pdb' to your INSTALLED_APPS

You can now run: manage.py runserver --pdb to break into pdb at the start of every view...

bash: manage.py runserver --pdb

Why not use them in the Users directory in the .bash_profile file, so you don't have to push any files with your variables to production?

For future googlers (thousands have now googled this question):

To set your mind at ease, the onClick event does work with divs in react, so double-check your code syntax.

These are right:

<div onClick={doThis}>
<div onClick={() => doThis()}>

These are wrong:

<div onClick={doThis()}>
<div onClick={() => doThis}>

(and don't forget to close your tags... Watch for this:

<div onClick={doThis}

missing closing tag on the div)

After nearly two hours of debugging I have concluded that the best solution to this is to give the file name a different name to the class that it contains. For Example:

Before example.php contains:

<?php
 class example {

 }

Solution: rename the file to example.class.php (or something like that), or rename the class to example_class (or something like that)

Hope this helps.

A couple other options:

1. Use the comma operator to create an array:

   $cars = ,"bmw"
   $cars.GetType().FullName
   # Outputs: System.Object[]
   

2. Use array subexpression syntax:

   $cars = @("bmw")
   $cars.GetType().FullName
   # Outputs: System.Object[]
   

If you don't want an object array you can downcast to the type you want e.g. a string array.

 [string[]] $cars = ,"bmw"
 [string[]] $cars = @("bmw")

Simple solution, try this.

String phoneNumberWithCountryCode = "+62820000000";
String message = "Hallo";

startActivity(
    new Intent(Intent.ACTION_VIEW,
        Uri.parse(
            String.format("https://api.whatsapp.com/send?phone=%s&text=%s", phoneNumberWithCountryCode, message)
        )
    )
);

I had the same problem with bootstrap. I solved with both outline and box-shadow

.btn:focus, .btn.focus {
    outline: none !important;
    box-shadow: 0 0 0 0 rgba(0, 123, 255, 0) !important; // or none
}

the best way to concat props/variables:

var sample = "test";    
var result = `this is just a ${sample}`;    
//this is just a test

I know this is an old question and was already answered, but for some reason, I still wanna post this alternative solution. I know it's easy to just find out which built-in function does the "magic" you need, but it doesn't hurt to know you can do it by yourself.

>>> list_1 = ['Ace', 'King']
>>> list_2 = ['Spades', 'Clubs', 'Diamonds']
>>> deck = []
>>> for i in range(max((len(list_1),len(list_2)))):
        while True:
            try:
                card = (list_1[i],list_2[i])
            except IndexError:
                if len(list_1)>len(list_2):
                    list_2.append('')
                    card = (list_1[i],list_2[i])
                elif len(list_1)<len(list_2):
                    list_1.append('')
                    card = (list_1[i], list_2[i])
                continue
            deck.append(card)
            break
>>>
>>> #and the result should be:
>>> print deck
>>> [('Ace', 'Spades'), ('King', 'Clubs'), ('', 'Diamonds')]

You would use a service for that in Angular. A service is a function you register with Angular, and that functions job is to return an object which will live until the browser is closed/refreshed. So it's a good place to store state in, and to synchronize that state with the server asynchronously as that state changes.

$a = 'This', 'Is', 'a', 'cat'

Using double quotes (and optionally use the separator $ofs)

# This Is a cat
"$a"

# This-Is-a-cat
$ofs = '-' # after this all casts work this way until $ofs changes!
"$a"

Using operator join

# This-Is-a-cat
$a -join '-'

# ThisIsacat
-join $a

Using conversion to [string]

# This Is a cat
[string]$a

# This-Is-a-cat
$ofs = '-'
[string]$a

# Save the script arguments
SCRIPT_NAME=$0
ARG_1=$1
ARGS_ALL=$*

function stuff {
  # use script args via the variables you saved
  # or the function args via $
  echo $0 $*
} 


# Call the function with arguments
stuff 1 2 3 4

using unescape(stringValue)

var str = "Passwords%20do%20not%20match%21";
document.write(unescape(str))

//Output
Passwords do not match!

use decodeURI(stringValue)

var str = "Passwords%20do%20not%20match%21";
 document.write(decodeURI(str))

Space = %20
? = %3F
! = %21
# = %23
...etc

You need to make the object first, then use [] to set it.

var key = "happyCount";
var obj = {};
obj[key] = someValueArray;
myArray.push(obj);

UPDATE 2018:

If you're able to use ES6 and Babel, you can use this new feature:

{
    [yourKeyVariable]: someValueArray,
}  

In a .txt file opened with Notepad++,
press Ctrl-F
go in the tab "Replace"
write the regex pattern \|.+ in the space Find what
and let the space Replace with blank

Then tick the choice matches newlines after the choice Regular expression
and press two times on the Replace button

If you have Python 2.6 installed then you already have simplejson - just import json; it's the same thing.

If you just want to apply new config you don't need to shut it down.

$ sudo service elasticsearch restart

But if you want to shut it down anyway:

$ sudo service elasticsearch stop

OR

$ sudo systemctl stop elasticsearch.service

$ sudo systemctl restart elasticsearch.service

Docker:

docker restart <elasticsearch-container-name or id>

mhh. I got another solution which helped me, 'cause I just have two different sates:

• either the item is not clicked
• or it is clicked and so it will be highlighted

In my .xml I define the ImageButton like this:

 <ImageButton
    android:id="@+id/imageButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/selector" />

The corresponding selector file looks like this:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/ico_100_checked" android:state_selected="true"/>
    <item android:drawable="@drawable/ico_100_unchecked"/>

</selector>

And in my onCreate I call:

final ImageButton ib = (ImageButton) value.findViewById(R.id.imageButton);

    OnClickListener ocl =new OnClickListener() {
        @Override
        public void onClick(View button) {
            if (button.isSelected()){
                button.setSelected(false);
            } else {
                ib.setSelected(false);
                //put all the other buttons you might want to disable here...
                button.setSelected(true);
            }
        }
    };

ib.setOnClickListener(ocl);
//add ocl to all the other buttons

done. hope this helps. took me a while to figure out.

If they have error pages enabled, you can go to a non-existent page and look at the bottom of the 404 page.

views.py

from django.contrib import messages 

def view_name(request):
    if request.method == 'POST':
        form = form_class(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks'/)
        else:
            messages.error(request, "Error")
return render(request, 'page.html', {'form':form_class()})

If you want to show the errors of the form other than that not valid just put {{form.as_p}} like what I did below

page.html

<html>
    <head>
        <script>
            {% if messages %}
                {% for message in messages %}
                    alert('{{message}}')
                {% endfor %}
            {% endif %}
        </script>
    </head>
    <body>
        {{form.as_p}}
    </body>
</html> 

You can use the click event and call your function or move your logic into the handler:

$("#bfCaptchaEntry").click(function(){ myFunction(); });

You can use the click event and set your function as the handler:

$("#bfCaptchaEntry").click(myFunction);

.click()

Bind an event handler to the "click" JavaScript event, or trigger that event on an element.

http://api.jquery.com/click/

You can use the on event bound to "click" and call your function or move your logic into the handler:

$("#bfCaptchaEntry").on("click", function(){ myFunction(); });

You can use the on event bound to "click" and set your function as the handler:

$("#bfCaptchaEntry").on("click", myFunction);

.on()

Attach an event handler function for one or more events to the selected elements.

I faced the same problem due to documentation inconsistencies. This page says the examples in the docs work best with python 3.x: https://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_setup/py_intro/py_intro.html#intro , whereas this installation page has links to python 2.7, and older versions of numpy and matplotlib: https://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_setup/py_setup_in_windows/py_setup_in_windows.html

My setup was as such: I already had Python 3.6 and 3.5 installed, but since OpenCv-python docs said it works best with 2.7.x, I also installed that version. After I installed numpy (in Python27 directory, without pip but with the default extractor, since pip is not part of the default python 2.7 installation like it is in 3.6), I ran in this RuntimeError: module compiled against API version a but this version of numpy is error. I tried many different versions of both numpy and opencv, but to no avail. Lastly, I simply deleted numpy from python27 (just delete the folder in site-packages as well as any other remaining numpy-named files), and installed the latest versions of numpy, matplotlib, and opencv in the Python3.6 version using pip no problem. Been running opencv ever since.

Hope this saves somebody some time.

The question itself has already been addressed above. Just adding part of the default values.

As per http://docs.oracle.com/cd/E13150_01/jrockit_jvm/jrockit/jrdocs/refman/optionX.html

The default value of Xmx will depend on platform and amount of memory available in the system.

Your syntax is wrong... The correct coding is:

 <?php
mysql_connect("localhost","root","");
mysql_select_db("form1");
$query = mysql_query("SELECT * FROM users WHERE name = 'Admin' ");
while($rows = mysql_fetch_array($query))
{

   $rows = $rows['Name'];
   $address = $rows['Address'];
   $email = $rows['Email'];
   $subject = $rows['Subject'];
   $comment = $rows['Comment']
   echo $rows.'</br>'.$address.'</br>'.$email.'</br>'.$subject.'</br>'.$comment;
}
   ?>

It is indeed possible.

Here is an example calling the Weather SOAP Service using plain requests lib:

import requests
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
#headers = {'content-type': 'application/soap+xml'}
headers = {'content-type': 'text/xml'}
body = """<?xml version="1.0" encoding="UTF-8"?>
         <SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" 
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
            <SOAP-ENV:Header/>
              <ns1:Body><ns0:GetWeatherInformation/></ns1:Body>
         </SOAP-ENV:Envelope>"""

response = requests.post(url,data=body,headers=headers)
print response.content

Some notes:

• The headers are important. Most SOAP requests will not work without the correct headers. application/soap+xml is probably the more correct header to use (but the weatherservice prefers text/xml
• This will return the response as a string of xml - you would then need to parse that xml.
• For simplicity I have included the request as plain text. But best practise would be to store this as a template, then you can load it using jinja2 (for example) - and also pass in variables.

For example:

from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('myapp', 'templates'))
template = env.get_template('soaprequests/WeatherSericeRequest.xml')
body = template.render()

Some people have mentioned the suds library. Suds is probably the more correct way to be interacting with SOAP, but I often find that it panics a little when you have WDSLs that are badly formed (which, TBH, is more likely than not when you're dealing with an institution that still uses SOAP ;) ).

You can do the above with suds like so:

from suds.client import Client
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
client = Client(url)
print client ## shows the details of this service

result = client.service.GetWeatherInformation() 
print result 

Note: when using suds, you will almost always end up needing to use the doctor!

Finally, a little bonus for debugging SOAP; TCPdump is your friend. On Mac, you can run TCPdump like so:

sudo tcpdump -As 0 

This can be helpful for inspecting the requests that actually go over the wire.

The above two code snippets are also available as gists:

• SOAP Request with requests
• SOAP Request with suds

When your project gets bigger, you might need some structure, so that your HTML page can reference files located in subfolders.

Assuming you drag your html_files folder to Xcode and select the Create folder references option, the following Swift code ensures that the WKWebView supports also the resulting folder structure:

import WebKit

@IBOutlet weak var webView: WKWebView!

if let path = Bundle.main.path(forResource: "sample", ofType: "html", inDirectory: "html_files") {
    webView.load( URLRequest(url: URL(fileURLWithPath: path)) )
}

This means that if your sample.html file contains an <img src="subfolder/myimage.jpg"> tag, then the image file myimage.jpg in subfolder will also be loaded and displayed.

I solved this issue by update Python3 Virtualenv on my mac. I reference the site https://gist.github.com/pandafulmanda/730a9355e088a9970b18275cb9eadef3
brew install python3
pip3 install virtualenv

make easy install again by downloading selenium webdriver from its website it is not installed properly.

Edit 1: extract the .tar.gz folder go inside the directory and run python setup.py install from terminal.make sure you have installed setuptools.

A simple change in Num2 class like this:

super().__init__(num) 

It works in python3.

class Num:
        def __init__(self,num):
                self.n1 = num

class Num2(Num):
        def __init__(self,num):
                super().__init__(num)
                self.n2 = num*2
        def show(self):
                print (self.n1,self.n2)

mynumber = Num2(8)
mynumber.show()

Look ma, no recursion!

struct llist * llist_merge(struct llist *one, struct llist *two, int (*cmp)(struct llist *l, struct llist *r) )
{
struct llist *result, **tail;

for (result=NULL, tail = &result; one && two; tail = &(*tail)->next ) {
        if (cmp(one,two) <=0) { *tail = one; one=one->next; }
        else { *tail = two; two=two->next; }
        }
*tail = one ? one: two;
return result;
}

try this:

use with responsive website (view in mobile or ipad)

jQuery(window).height();   // return height of browser viewport
jQuery(window).width();    // return width of browser viewport

rarely use

jQuery(document).height(); // return height of HTML document
jQuery(document).width();  // return width of HTML document

You want an outer join for this (and you need to use person as the "driving" table)

SELECT person.person_id, COUNT(appointment.person_id) AS "number_of_appointments"
FROM person 
  LEFT JOIN appointment ON person.person_id = appointment.person_id
GROUP BY person.person_id;

The reason why this is working, is that the outer (left) join will return NULL for those persons that do not have an appointment. The aggregate function count() will not count NULL values and thus you'll get a zero.

If you want to learn more about outer joins, here is a nice tutorial: http://sqlzoo.net/wiki/Using_Null

For anyone who must use the ssh keys (for a corporate server).

Just add -i /.ssh/id_rsa at the end.

$ ssh -N -f -L localhost:8211:localhost:6007 myname@servername -i /.ssh/id_rsa

try

netstat -a -t -n | grep 3306 

to see any one listening to the 3306 port then kill it

I was having this problem for 2 days. Trying out the solutions posted on forums I accidentally ran into a situation where my log was getting this error

check that you do not already have another mysqld process

You may use a local variable, like:

    float[] values = new float[3];
    float[] v = {0.1f, 0.2f, 0.3f};
    float[] values = v;

I think the best way is using margin instead of display.

I.e.:

.pagination a {
    margin-left: auto;
    margin-right: auto;
    width: 30px;
    height: 30px;    
    background: url(/images/structure/pagination-button.png);
}

Check the result and the code:

As I mentioned in this answer, if the server runs on a port other than 80 (as might be common on a development/intranet machine) then HTTP_HOST contains the port, while SERVER_NAME does not.

$_SERVER['HTTP_HOST'] == 'localhost:8080'
$_SERVER['SERVER_NAME'] == 'localhost'

(At least that's what I've noticed in Apache port-based virtualhosts)

Note that HTTP_HOST does not contain :443 when running on HTTPS (unless you're running on a non-standard port, which I haven't tested).

As others have noted, the two also differ when using IPv6:

$_SERVER['HTTP_HOST'] == '[::1]'
$_SERVER['SERVER_NAME'] == '::1'

Works for me. You probably want to multiplz it with 1000, since what you get are the seconds from 1970 and you have to pass the milliseconds from jan 1 1970

if you want to access this programatically, you can do it by figuring out the version of eclipse\plugins\org.eclipse.platform_ plugin

    String platformFile = <the above file>; //actually directory

versionPattern = Pattern.compile("\\d\\.\\d\\.\\d");
Matcher m = versionPattern.matcher(platformFile);
return m.group();

There are tree ways methods and properties are implemented on function or class objects, and on they instances.

1. On the class (or function) itself : Foo.method() or Foo.prop. Those are static methods or properties
2. On its prototype : Foo.prototype.method() or Foo.prototype.prop. When created, the instances will inherit those object via the prototype witch is {method:function(){...}, prop:...}. So the foo object will receive, as prototype, a copy of the Foo.prototype object.
3. On the instance itself : the method or property is added to the object itself. foo={method:function(){...}, prop:...}

The this keyword will represent and act differently according to the context. In a static method, it will represent the class itself (witch is after all an instance of Function : class Foo {} is quite equivalent to let Foo = new Function({})

With ECMAScript 2015, that seems well implemented today, it is clearer to see the difference between class (static) methods and properties, instance methods and properties and own methods ans properties. You can thus create three method or properties having the same name, but being different because they apply to different objects, the this keyword, in methods, will apply to, respectively, the class object itself and the instance object, by the prototype or by its own.

class Foo {
  constructor(){super();}
  
  static prop = "I am static" // see 1.
  static method(str) {alert("static method"+str+" :"+this.prop)} // see 1.
  
  prop="I am of an instance"; // see 2.
  method(str) {alert("instance method"+str+" : "+this.prop)} // see 2.
}

var foo= new Foo();
foo.prop = "I am of own";  // see 3.
foo.func = function(str){alert("own method" + str + this.prop)} // see 3.

Use \D to match non-digit characters.

preg_replace('~\D~', '', $str);

The ServerUtility class is available as an instance in your HttpContext. If you're in an environment where you know it'll be executed inside the ASP.Net pipeline, you can use

HttpContext.Current.Server.MapPath()

You'll have to import System.Web though.

The error "only length-1 arrays can be converted to Python scalars" is raised when the function expects a single value but you pass an array instead.

If you look at the call signature of np.int, you'll see that it accepts a single value, not an array. In general, if you want to apply a function that accepts a single element to every element in an array, you can use np.vectorize:

import numpy as np
import matplotlib.pyplot as plt

def f(x):
    return np.int(x)
f2 = np.vectorize(f)
x = np.arange(1, 15.1, 0.1)
plt.plot(x, f2(x))
plt.show()

You can skip the definition of f(x) and just pass np.int to the vectorize function: f2 = np.vectorize(np.int).

Note that np.vectorize is just a convenience function and basically a for loop. That will be inefficient over large arrays. Whenever you have the possibility, use truly vectorized functions or methods (like astype(int) as @FFT suggests).

Here is something to try, using interface and destructuring with default values. Please note that "lastName" is optional.

interface IName {
  firstName: string
  lastName?: string
}

function sayName(params: IName) {
  const { firstName, lastName = "Smith" } = params
  const fullName = `${firstName} ${lastName}`

  console.log("FullName-> ", fullName)
}

sayName({ firstName: "Bob" })

my approach was to use response.content (blob) and save to the file in binary mode

img_blob = requests.get(url, timeout=5).content
     with open(destination + '/' + title, 'wb') as img_file:
         img_file.write(img_blob)

I just replicate the 2 attributes of the btn-navbar (data-toggle="collapse" data-target=".nav-collapse.in") on each link like this:

<div class="nav-collapse">
  <ul class="nav" >
    <li class="active"><a href="#home" data-toggle="collapse" data-target=".nav-collapse.in">Home</a></li>
    <li><a href="#about" data-toggle="collapse" data-target=".nav-collapse.in">About</a></li>
    <li><a href="#portfolio" data-toggle="collapse" data-target=".nav-collapse.in">Portfolio</a></li>
    <li><a href="#services" data-toggle="collapse" data-target=".nav-collapse.in">Services</a></li>
    <li><a href="#contact" data-toggle="collapse" data-target=".nav-collapse.in">Contact</a></li>
  </ul>
</div>

In the Bootstrap 4 Navbar, in has changed to show so the syntax would be:

data-toggle="collapse" data-target=".navbar-collapse.show"

I had a similar problem, but in my case the default value was in database. Below is the solution for that:

 @Configuration
 public class AppConfiguration {
 @Autowired
 private AppConfigDao appConfigDao;

 @Bean
 public Jackson2ObjectMapperBuilder builder() {
   Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder()
       .deserializerByType(SomeDto.class, 
 new SomeDtoJsonDeserializer(appConfigDao.findDefaultValue()));
   return builder;
 }

Then in SomeDtoJsonDeserializer use ObjectMapper to deserialize the json and set default value if your field/object is null.

To access properties and methods of a parent class use the base keyword. So in your child class LoadData() method you would do this:

public class Child : Parent 
{
    public void LoadData() 
    {
        base.MyMethod(); // call method of parent class
        base.CurrentRow = 1; // set property of parent class
        // other stuff...
    }
}

Note that you would also have to change the access modifier of your parent MyMethod() to at least protected for the child class to access it.

In ES6, imports are live read-only views on exported-values. As a result, when you do import a from "somemodule";, you cannot assign to a no matter how you declare a in the module.

However, since imported variables are live views, they do change according to the "raw" exported variable in exports. Consider the following code (borrowed from the reference article below):

//------ lib.js ------
export let counter = 3;
export function incCounter() {
    counter++;
}

//------ main1.js ------
import { counter, incCounter } from './lib';

// The imported value `counter` is live
console.log(counter); // 3
incCounter();
console.log(counter); // 4

// The imported value can’t be changed
counter++; // TypeError

As you can see, the difference really lies in lib.js, not main1.js.

To summarize:

• You cannot assign to import-ed variables, no matter how you declare the corresponding variables in the module.
• The traditional let-vs-const semantics applies to the declared variable in the module.
  • If the variable is declared const, it cannot be reassigned or rebound in anywhere.
  • If the variable is declared let, it can only be reassigned in the module (but not the user). If it is changed, the import-ed variable changes accordingly.

You can create render the results (payments) and use a fancy way to iterate over items instead of adding a for loop.

const noGuest = 3;_x000D_
_x000D_
Array(noGuest).fill(noGuest).map(guest => {_x000D_
  console.log(guest);_x000D_
});

Example:

renderPayments(noGuest) {
  return Array(noGuest).fill(noGuest).map((guess, index) => {
    return(
      <View key={index}>
        <View><TextInput /></View>
        <View><TextInput /></View>
        <View><TextInput /></View>
      </View>
    );
  }
}

Then use it where you want it

render() {
  return(
     const { guest } = this.state;
     ...
     {this.renderPayments(guest)}
  );
}

Hope you got the idea.

If you want to understand this in simple Javascript check Array.prototype.fill()

You could create a git repo and setup a link to the node git repo as a dependency. Then any user who clones the repo could also install node.

#git submodule [--quiet] add [-b branch] [-f|--force]
git submodule add /var/Node-repo.git common

You could easily package a script up to automatically clone the git repo you have hosted somewhere and "install" from one that one script file.

#!/bin/sh
#clone git repo
git clone your-repo.git
