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.

In my case, the issue was new sites had an implicit deny of all IP addresses unless an explicit allow was created. To fix: Under the site in Features View: Under the IIS Section > IP Address and Domain Restrictions > Edit Feature Settings > Set 'Access for unspecified clients:' to 'Allow'

For the primitive types, the 'final static' will be a proper declaration to declare a constant. A non-static final variable makes sense when it is a constant reference to an object. In this case each instance can contain its own reference, as shown in JLS 4.5.4.

See Pavel's response for the correct answer.

I guess something like this would work:

Add System.ServiceProcess to your project references (It's on the .NET tab).

using System.ServiceProcess;

ServiceController sc = new ServiceController(SERVICENAME);

switch (sc.Status)
{
    case ServiceControllerStatus.Running:
        return "Running";
    case ServiceControllerStatus.Stopped:
        return "Stopped";
    case ServiceControllerStatus.Paused:
        return "Paused";
    case ServiceControllerStatus.StopPending:
        return "Stopping";
    case ServiceControllerStatus.StartPending:
        return "Starting";
    default:
        return "Status Changing";
}

Edit: There is also a method sc.WaitforStatus() that takes a desired status and a timeout, never used it but it may suit your needs.

Edit: Once you get the status, to get the status again you will need to call sc.Refresh() first.

Reference: ServiceController object in .NET.

Bitmap is Parcelable so you can add using [putExtra(String,Parcelable)][2] method, But not sure it is a best practice, If it is large size data it is better to store in a single place and use from both activities.

[2]: http://developer.android.com/reference/android/content/Intent.html#putExtra(java.lang.String, android.os.Parcelable)

using

host.docker.internal

instead of

localhost

works flawlessly for me.

For me with FreeBSD 10.1 with sed worked only this solution:

sed -e '/^[     ]*$/d' "testfile"

inside [] there are space and tab symbols.

test file contains:

fffffff next 1 tabline ffffffffffff

ffffffff next 1 Space line ffffffffffff

ffffffff empty 1 lines ffffffffffff

Be careful to type exactly :wq as Wouter Verleur said at step 7. After type enter, you will save the changes and exit the visudo editor to bash.

Delete all but the necessary certificate from your browser's certificate store and then configure the browser to automatically select the certificate when only one certificate is present.

I know this is an old post and that it wants an answer for .NET 1.1 but there's already a very good answer for that. I thought it would be good to have an answer for those people who land on this post that may have a more recent version of the .Net framework, such as myself when I went looking for an answer to the same question.

In those cases there is an even simpler way to write the contents of a StringBuilder to a text file. It can be done with one line of code. It may not be the most efficient but that wasn't really the question now was it.

System.IO.File.WriteAllText(@"C:\MyDir\MyNewTextFile.txt",sbMyStringBuilder.ToString());

You will use props in your child component

for example

if your now component props is

{
   booking: 4,
   isDisable: false
}

you can use this props in your child compoenet

 <div {...this.props}> ... </div>

in you child component, you will receive all your parent props.

Ok @Adam and @Kimvais were right, paramiko cannot parse .ppk files.

So the way to go (thanks to @JimB too) is to convert .ppk file to openssh private key format; this can be achieved using Puttygen as described here.

Then it's very simple getting connected with it:

import paramiko
ssh = paramiko.SSHClient()

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh.connect('<hostname>', username='<username>', password='<password>', key_filename='<path/to/openssh-private-key-file>')

stdin, stdout, stderr = ssh.exec_command('ls')
print stdout.readlines()
ssh.close()

Yes it is possible, but not with the usual comma-separated insert values.

Try this...

insert into myTable (col1,col2) 
     select aValue as col1,anotherValue as col2 
     union select moreValue,evenMoreValue 
     union...

Yes, it's a little ugly but easy enough to automate the generation of the statement from a set of values. Also, it appears you only need to declare the column names in the first select.

For those who need the same feature in IE 8, this is how I solved the problem:

  var myImage = $('<img/>');

               myImage.attr('width', 300);
               myImage.attr('height', 300);
               myImage.attr('class', "groupMediaPhoto");
               myImage.attr('src', photoUrl);

I could not force IE8 to use object in constructor.

This is the procedure that seems simplest to me:

SharedPreferences sp = getSharedPreferences("MySharedPrefs", MODE_PRIVATE);
SharedPreferences.Editor e = sp.edit();

    if (sp.getString("sharedString", null).equals("true")
            || sp.getString("sharedString", null) == null) {
        e.putString("sharedString", "false").commit();
        // Do something
    } else {
        // Do something else
    }

Create a wrapper module project/bin/lib, which contains this:

import sys, os

sys.path.insert(0, os.path.join(
    os.path.dirname(os.path.dirname(os.path.realpath(__file__))), 'lib'))

import mylib

del sys.path[0], sys, os

Then you can replace all the cruft at the top of your scripts with:

#!/usr/bin/python
from lib import mylib

function bindAllEvents (el) {
  for (const key in el) {
      if (key.slice(0, 2) === 'on') {
          el.addEventListener(key.slice(2), e => console.log(e.type));
      }
  }
}
bindAllEvents($('.yourElement'))

This uses a bit of ES6 for prettiness, but can easily be translated for legacy browsers as well. In the function attached to the event listeners, it's currently just logging out what kind of event occurred but this is where you could print out additional information, or using a switch case on the e.type, you could only print information on specific events

FYI, another way this exception can occur is if:

• Your transaction isolation is READ_COMMITTED
• Transaction #1 queries for an entity, then deletes that entity
• A simultaneous transaction #2 does the same thing

Then this can happen: TX #1 successfully commits before TX #2, then when TX #2 tries to delete the entity (again) it's not there any more - even though it was found by a query earlier in that same transaction. Note this anomaly is allowed with READ_COMMITTED isolation.

In my case the resulting exception looked like this:

HHH000315: Exception executing batch [org.hibernate.StaleStateException:
  Batch update returned unexpected row count from update [0]; actual row
  count: 0; expected: 1; statement executed: delete from Foobar where id=?],
  SQL: delete from Foobar where id=?

I can explain how i get into the similar situation, and then will list steps that i have taken to solve this issue.

I am using
Windows 10,
git: git version 2.27.0.windows.1.

I had already setup the git and was doing git push activities. Windows Credential Manager stores the username and password so you don't have to enter username and password every git remote activities.

The encounter this problem, when i added another github account and used --local git settings. After few days, I encounter the Repository not found problem, upon investigation i found:

1. Even if you remove the git details from Windows Credential Manager, it will save again the username, email details you enter.

So, if you are using two git accounts, you need to use (git bash as an administrator)

git config --edit --system 

and remove the

helper = manager 

line so that it is no longer registered as a credential helper. But it will ask you login details every time you do any remote activities.

How do I disable Git Credential Manager for Windows?.

To check remote origin, user details

git config --list --show-origin

Fundamentally you hadn't declare location which is what nginx uses to bind URL with resources.

 server {
            listen       80;
            server_name  localhost;

            access_log  logs/localhost.access.log  main;

            location / {
                root /var/www/board/public;
                index index.html index.htm index.php;
            }
       }

For anyone want to replace your script.

update dbo.[TABLE_NAME] set COLUMN_NAME= replace(COLUMN_NAME, 'old_value', 'new_value') where COLUMN_NAME like %CONDITION%

JSONObject jsonObject =new JSONObject(jsonStr);
JSONArray jsonArray = jsonObject.getJSONArray("data");
for(int i=0;i<jsonArray.length;i++){
    JSONObject json = jsonArray.getJSONObject(i);
    String id = json.getString("id");
    String name=json.getString("name");
    JSONArray ingArray = json.getJSONArray("Ingredients") // here you are going   to get ingredients
    for(int j=0;j<ingArray.length;j++){
        JSONObject ingredObject= ingArray.getJSONObject(j);
        String ingName = ingredObject.getString("name");//so you are going to get   ingredient name
        Log.e("name",ingName); // you will get 
   }
}

 # Check delegate? first must be connected owner of view controller

    # Simple implementation of the didSelectRowAt function.

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
         print("row selection: \(indexPath.row)")
    }

if the content of foo.py

print __name__
if __name__ == '__main__':
    print 'XXXX'

A file foo.py can be used in two ways.

• imported in another file : import foo

In this case __name__ is foo, the code section does not get executed and does not print XXXX.

• executed directly : python foo.py

When it is executed directly, __name__ is same as __main__ and the code in that section is executed and prints XXXX

One of the use of this functionality to write various kind of unit tests within the same module.

You're giving parameters to your program instead to Java. Use

java -Dtest="true" -jar myApplication.jar 

instead.

Consider using

"true".equalsIgnoreCase(System.getProperty("test"))

to avoid the NPE. But do not use "Yoda conditions" always without thinking, sometimes throwing the NPE is the right behavior and sometimes something like

System.getProperty("test") == null || System.getProperty("test").equalsIgnoreCase("true")

is right (providing default true). A shorter possibility is

!"false".equalsIgnoreCase(System.getProperty("test"))

but not using double negation doesn't make it less hard to misunderstand.

I couldn't leave this question here with out a single statement using the modulo operator.

def rot13(s):
    return ''.join([chr(x.islower() and ((ord(x) - 84) % 26) + 97
                        or x.isupper() and ((ord(x) - 52) % 26) + 65
                        or ord(x))
                    for x in s])

This is not pythonic nor good practice, but it works!

>> rot13("Hello World!")
Uryyb Jbeyq!

You can simply put "." the dot sign. I've had a cmd application that was requiring the path and I was already in the needed directory and I used the dot symbol.

Hope it helps.

it's well documented here:

https://cwiki.apache.org/confluence/display/TOMCAT/Connectors#Connectors-Q6

How do I bind to a specific ip address? - "Each Connector element allows an address property. See the HTTP Connector docs or the AJP Connector docs". And HTTP Connectors docs:

http://tomcat.apache.org/tomcat-7.0-doc/config/http.html

Standard Implementation -> address

"For servers with more than one IP address, this attribute specifies which address will be used for listening on the specified port. By default, this port will be used on all IP addresses associated with the server."

In java8 IntSteam stream can be boxed to stream of Integers.

public static Iterable<Integer> toIterable(int[] ints) {
    return IntStream.of(ints).boxed().collect(Collectors.toList());
}

I think performance matters based on the size of the array.

Another way ( longer ) In VB.net [ Say 2300 Start and 0700 Finish next day ]

If tsStart > tsFinish Then

                            ' Take Hours difference and adjust accordingly
                            tsDifference = New TimeSpan((24 - tsStart.Hours) + tsFinish.Hours, 0, 0)

                            ' Add Minutes to Difference
                            tsDifference = tsDifference.Add(New TimeSpan(0, Math.Abs(tsStart.Minutes - tsFinish.Minutes), 0))


                            ' Add Seonds to Difference
                            tsDifference = tsDifference.Add(New TimeSpan(0, 0, Math.Abs(tsStart.Seconds - tsFinish.Seconds)))

I liked the simplest answer provided. However, I didn't like the choppiness of the collapsing. So I combined a solution from this question: How to Use slideDown (or show) function on a table row? to make it a smoother animation when the rows slide up or down. It involves having to wrap the content of each td in a div. This allows it to smoothly animate the collapsing. When the rows are expanded, it will replace the div, with just the content.

So here's the html:

<table>
<tr class="header">
    <td>CARS</td>
</tr>
<tr class="thing">
    <td>car</td>
</tr>
<tr class="thing">
    <td>truck</td>
</tr>
<tr class="header">
    <td>HOUSES</td>
</tr>
<tr class="thing">
    <td>split level</td>
</tr>
<tr class="thing">
    <td>trailer</td>
</tr>

And here's the js

$('.header').click(function(){
if($(this).hasClass("collapsed")){
    $(this).nextUntil('tr.header')
    .find('td')
    .parent()
    .find('td > div')
    .slideDown("fast", function(){
        var $set = $(this);
        $set.replaceWith($set.contents());
    });
    $(this).removeClass("collapsed");
} else {
    $(this).nextUntil('tr.header')
    .find('td')
    .wrapInner('<div style="display: block;" />')
    .parent()
    .find('td > div')
    .slideUp("fast");
    $(this).addClass("collapsed");
}
});

1- There is no way to actually destroy an object in javascript, but using delete, we could remove a reference from an object:

var obj = {};
obj.mypointer = null;
delete obj.mypointer;

2- The important point about the delete keyword is that it does not actually destroy the object BUT if only after deleting that reference to the object, there is no other reference left in the memory pointed to the same object, that object would be marked as collectible. The delete keyword deletes the reference but doesn't GC the actual object. it means if you have several references of the same object, the object will be collected just after you delete all the pointed references.

3- there are also some tricks and workarounds that could help us out, when we want to make sure we do not leave any memory leaks behind. for instance if you have an array consisting several objects, without any other pointed reference to those objects, if you recreate the array all those objects would be killed. For instance if you have var array = [{}, {}] overriding the value of the array like array = [] would remove the references to the two objects inside the array and those two objects would be marked as collectible.

4- for your solution the easiest way is just this:

var storage = {};
storage.instance = new Class();
//since 'storage.instance' is your only reference to the object, whenever you wanted to destroy do this:
storage.instance = null;
// OR
delete storage.instance;

As mentioned above, either setting storage.instance = null or delete storage.instance would suffice to remove the reference to the object and allow it to be cleaned up by the GC. The difference is that if you set it to null then the storage object still has a property called instance (with the value null). If you delete storage.instance then the storage object no longer has a property named instance.

and WHAT ABOUT destroy method ??

the paradoxical point here is if you use instance.destroy in the destroy function you have no access to the actual instance pointer, and it won't let you delete it.

The only way is to pass the reference to the destroy function and then delete it:

// Class constructor
var Class = function () {
     this.destroy = function (baseObject, refName) {
         delete baseObject[refName];
     };
};

// instanciate
var storage = {};
storage.instance = new Class();
storage.instance.destroy(object, "instance");
console.log(storage.instance); // now it is undefined

BUT if I were you I would simply stick to the first solution and delete the object like this:

storage.instance = null;
// OR
delete storage.instance;

WOW it was too much :)

just add in your backend API new property's into response body. from example .net core:

[Authorize]
[HttpGet]
public async Task<IActionResult> GetUsers([FromQuery]UserParams userParams)
{
  var users = await _repo.GetUsers(userParams);
  var usersToReturn = _mapper.Map<IEnumerable<UserForListDto>>(users);


  // create new object and add into it total count param etc
  var UsersListResult = new
  {
    usersToReturn,
    currentPage = users.CurrentPage,
    pageSize = users.PageSize,
    totalCount = users.TotalCount,
    totalPages = users.TotalPages
  };

  return Ok(UsersListResult);
}

In body response it look like this

{
"usersToReturn": [
    {
        "userId": 1,
        "username": "[email protected]",
        "firstName": "Joann",
        "lastName": "Wilson",
        "city": "Armstrong",
        "phoneNumber": "+1 (893) 515-2172"
    },
    {
        "userId": 2,
        "username": "[email protected]",
        "firstName": "Booth",
        "lastName": "Drake",
        "city": "Franks",
        "phoneNumber": "+1 (800) 493-2168"
    }
],
// metadata to pars in client side
"currentPage": 1,
"pageSize": 2,
"totalCount": 87,
"totalPages": 44

}

if this is what you want .

Try invoking your command with Invoke-Expression:

Invoke-Expression $cmd1

Here is a working example on my machine:

$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd

iex is an alias for Invoke-Expression so you could do:

iex $cmd1

Good Luck...

This is a really unclear and unhelpful error message. After much trial and error I found that LocalDateTime will give the above error if you do not attempt to parse a time. By using LocalDate instead, it works without erroring.

This is poorly documented and the related exception is very unhelpful.

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

LocalForward 5901 computer.myHost.edu:5901

Manual cleanup:

You can KILL the processid.

mysql> show full processlist;
+---------+------------+-------------------+------+---------+-------+-------+-----------------------+
| Id      | User       | Host              | db   | Command | Time  | State | Info                  |
+---------+------------+-------------------+------+---------+-------+-------+-----------------------+
| 1193777 | TestUser12 | 192.168.1.11:3775 | www  | Sleep   | 25946 |       | NULL                  |
+---------+------------+-------------------+------+---------+-------+-------+-----------------------+

mysql> kill 1193777;

But:

• the php application might report errors (or the webserver, check the error logs)
• don't fix what is not broken - if you're not short on connections, just leave them be.

Automatic cleaner service ;)

Or you configure your mysql-server by setting a shorter timeout on wait_timeout and interactive_timeout

mysql> show variables like "%timeout%";
+--------------------------+-------+
| Variable_name            | Value |
+--------------------------+-------+
| connect_timeout          | 5     |
| delayed_insert_timeout   | 300   |
| innodb_lock_wait_timeout | 50    |
| interactive_timeout      | 28800 |
| net_read_timeout         | 30    |
| net_write_timeout        | 60    |
| slave_net_timeout        | 3600  |
| table_lock_wait_timeout  | 50    |
| wait_timeout             | 28800 |
+--------------------------+-------+
9 rows in set (0.00 sec)

Set with:

set global wait_timeout=3;
set global interactive_timeout=3;

(and also set in your configuration file, for when your server restarts)

But you're treating the symptoms instead of the underlying cause - why are the connections open? If the PHP script finished, shouldn't they close? Make sure your webserver is not using connection pooling...

Not sure if this is a feature or a bug but this worked for us:

git commit '' -m "Message"

Note the empty file list ''. Git interprets this to commit all modified tracked files, even if they are not staged, and ignore untracked files.

There is a workaround to guarantee that one handler happens after another: attach the second handler to a containing element and let the event bubble up. In the handler attached to the container, you can look at event.target and do something if it's the one you're interested in.

Crude, maybe, but it definitely should work.

You would have to first create your migration for the model basics then you create another migration to modify your previous using the change_column ...

def change
    change_column :widgets, :colour, :string, default: 'red'
end

The current recommended best practice from Apple is for IBOutlets to be strong unless weak is specifically needed to avoid a retain cycle. As Johannes mentioned above, this was commented on in the "Implementing UI Designs in Interface Builder" session from WWDC 2015 where an Apple Engineer said:

And the last option I want to point out is the storage type, which can either be strong or weak. In general you should make your outlet strong, especially if you are connecting an outlet to a subview or to a constraint that's not always going to be retained by the view hierarchy. The only time you really need to make an outlet weak is if you have a custom view that references something back up the view hierarchy and in general that's not recommended.

I asked about this on Twitter to an engineer on the IB team and he confirmed that strong should be the default and that the developer docs are being updated.

For me the problem was that I was using obsolete versions of the cordova android and ios platforms. So upgrading to [email protected] and [email protected] solved it.

You can upgrade to these specific versions:

cordova platforms rm android
cordova platforms add [email protected]
cordova platforms rm ios
cordova platforms add [email protected]

It is, however,accesible via that http://192.168.99.100:30454.

I used:

var List<int> = new List<int>();
List.add("Test");
List.add("Test2");
List1.add(List);
var List<int> = new List<int>();
List.add("Test3");
List1.add(List);

that equals:

List1
(
[0] => List2 // List1[0][x]
    (
        [0] => Test  // List[0][0] etc.
        [1] => Test2

    )
[1] => List2
    (
        [0] => Test3

For SQL Server, you can use tool Import Data from another Database, It's easier to configuration mapping columns.

$("button").click(function() {
    alert(this.id);
});

Just use:

overflow: hidden;
white-space: nowrap;

In your item's divs

While you asked how to kill a window resp. pane, I often wouldn't want to kill it but simply to get it back to a working state (the layout of panes is of importance to me, killing a pane destroys it so I must recreate it); tmux provides the respawn commands to that effect: respawn-pane resp. respawn-window. Just that people like me may find this solution here.

If you are looking for a modern >1.7 Dojo way of destroying all node's children this is the way:

// Destroys all domNode's children nodes
// domNode can be a node or its id:
domConstruct.empty(domNode);

Safely empty the contents of a DOM element. empty() deletes all children but keeps the node there.

Check "dom-construct" documentation for more details.

// Destroys domNode and all it's children
domConstruct.destroy(domNode);

Destroys a DOM element. destroy() deletes all children and the node itself.

Use method=POST then it will pass key&value.

use of %

def percent(expression):
    if "%" in expression:
        expression = expression.replace("%","/100")
    return eval(expression)

>>> percent("1500*20%")
300.0

Somthing simple

>>> p = lambda x: x/100
>>> p(20)
0.2
>>> 100*p(20)
20.0
>>>

In Grid use this code having ID as your Primary Element so to uniquely identify each ROW

<asp:TemplateField>
            <ItemTemplate>
            <asp:HiddenField ID="Hf_ID" runat="server" Value='<%# Eval("ID") %>' />
            </ItemTemplate>
</asp:TemplateField>

and to search the uique ID use the code in C# code behind (basically this is searching hidden field and storing it in a var)

protected void Grd_Registration_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        var ID = (HiddenField)Grd_Registration.Rows[e.RowIndex].FindControl("ID");
        //Your Delete Logic Goes here having ID to delete

        GridBind();

    }

Try this

$('#add_here').text('new-dynamic-text');

nvarchar(max) is what you want to be using. The biggest advantage is that you can use all the T-SQL string functions on this data type. This is not possible with ntext. I'm not aware of any real disadvantages.

In WPF, TextBox element will not get opportunity to use "Enter" button for creating KeyUp Event until you will not set property: AcceptsReturn="True".

But, it would`t solve the problem with handling KeyUp Event in TextBox element. After pressing "ENTER" you will get a new text line in TextBox.

I had solved problem of using KeyUp Event of TextBox element by using Bubble event strategy. It's short and easy. You have to attach a KeyUp Event handler in some (any) parent element:

XAML:

<Window x:Class="TextBox_EnterButtomEvent.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:TextBox_EnterButtomEvent"
    mc:Ignorable="d"
    Title="MainWindow" Height="350" Width="525">
<Grid KeyUp="Grid_KeyUp">
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height ="0.3*"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <TextBlock Grid.Row="1" Grid.Column="1" Padding="0" TextWrapping="WrapWithOverflow">
        Input text end press ENTER:
    </TextBlock>
    <TextBox Grid.Row="2" Grid.Column="1" HorizontalAlignment="Stretch"/>
    <TextBlock Grid.Row="4" Grid.Column="1" Padding="0" TextWrapping="WrapWithOverflow">
        You have entered:
    </TextBlock>
    <TextBlock Name="txtBlock" Grid.Row="5" Grid.Column="1" HorizontalAlignment="Stretch"/>
</Grid></Window>

C# logical part (KeyUp Event handler is attached to a grid element):

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Grid_KeyUp(object sender, KeyEventArgs e)
    {
        if(e.Key == Key.Enter)
        {
            TextBox txtBox = e.Source as TextBox;
            if(txtBox != null)
            {
                this.txtBlock.Text = txtBox.Text;
                this.txtBlock.Background = new SolidColorBrush(Colors.LightGray);
            }
        }
    }
}

Result:

REAL is what you are looking for. Documentation of SQLite datatypes

My two cents for Xcode 8:

a) A custom flag using the -D prefix works fine, but...

b) Simpler use:

In Xcode 8 there is a new section: "Active Compilation Conditions", already with two rows, for debug and release.

Simply add your define WITHOUT -D.

Guava library has PercentEscaper:

Escaper percentEscaper = new PercentEscaper("-_.*", false);

"-_.*" are safe characters

false says PercentEscaper to escape space with '%20', not '+'

date.parse(valueToBeTested) > 0 is all that's needed. A valid date will return the epoch value and an invalid value will return NaN which will fail > 0 test by virtue of not even being a number.

This is so simple that a helper function won't save code though it might be a bit more readable. If you wanted one:

String.prototype.isDate = function() {
  return !Number.isNaN(Date.parse(this));
}

OR

To use:

"StringToTest".isDate();

A Magento Module is a group of directories containing blocks, controllers, helpers, and models that are needed to create a specific store feature. It is the unit of customization in the Magento platform. Magento Modules can be created to perform multiple functions with supporting logic to influence user experience and storefront appearance. It has a life cycle that allows them to be installed, deleted, or disabled. From the perspective of both merchants and extension developers, modules are the central unit of the Magento platform.

Declaration of Module

We have to declare the module by using the configuration file. As Magento 2 search for configuration module in etc directory of the module. So now we will create configuration file module.xml.

The code will look like this:

<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd"> <module name="Cloudways_Mymodule" setup_version="1.0.0"></module> </config>

Registration of Module The module must be registered in the Magento 2 system by using Magento Component Registrar class. Now we will create the file registration.php in the module root directory:

app/code/Cloudways/Mymodule/registration.php

The Code will look like this:

?php
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Cloudways_Mymodule',
__DIR__
);

Check Module Status After following the steps above, we would have created a simple module. Now we are going to check the status of the module and whether it is enabled or disabled by using the following command line:

php bin/magento module:status

php bin/magento module:enable Cloudways_Mymodule

Share your feedback once you have gone through complete process

If you are inserting using PHP, and you have followed the various ALTER database and ALTER table options above, make sure your php connection's charset is utf8mb4.

Example of connection string:

$this->pdo = new PDO("mysql:host=$ip;port=$port;dbname=$db;charset=utf8mb4", etc etc

Notice the "charset" is utf8mb4, not just utf8!

It is better to look up shadow:

.header{
    -webkit-box-shadow: 0 -8px 73px 0 rgba(0,0,0,0.2);
    -moz-box-shadow: 0 -8px 73px 0 rgba(0,0,0,0.2);
    box-shadow: 0 -8px 73px 0 rgba(0,0,0,0.2);
}

this code is currently using on stackoverflow web.

                            mTouchListener.onListViewPulledDown();
                            setPulledDown(false);
                        }
                    }
                }
            }, 400);
            lastY = newY;
        } else if (ev.getAction() == MotionEvent.ACTION_UP) {
            lastY = 0;
        }
        return super.dispatchTouchEvent(ev);
    }

    @Override
    public void onScroll(AbsListView view, int firstVisibleItem,
            int visibleItemCount, int totalItemCount) {
        setPulledDown(false);
    }

    @Override
    public void onScrollStateChanged(AbsListView view, int scrollState) {
    }

    public interface ListViewTouchEventListener {
        public void onListViewPulledDown();
    }

    public void setListViewTouchListener(
            ListViewTouchEventListener touchListener) {
        this.mTouchListener = touchListener;
    }

    public ListViewTouchEventListener getListViewTouchListener() {
        return mTouchListener;
    }

    public boolean isPulledDown() {
        return pulledDown;
    }

    public void setPulledDown(boolean pulledDown) {
        this.pulledDown = pulledDown;
    }
}

You just need to implement ListViewTouchEventListener on your activity where you want to use this ListView and set the listener

I have it implemented in PullDownListViewActivity

package com.myproject.activities;

import android.app.Activity;
import android.os.Bundle;

/**
 * @author Pushpan
 *
 */
public class PullDownListViewActivity extends Activity implements ListViewTouchEventListener {

    private PullDownListView listView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        listView = new PullDownListView(this);
        setContentView(listView);
        listView.setListViewTouchListener(this);

        //setItems in listview
    }

    public void onListViewPulledDown(){
        Log.("PullDownListViewActivity", "ListView pulled down");
    }
}

It works for me :)

You can create your own custom Dialog. It's fairly easy. If you want to dismiss it with a selection in the spinner, then add an OnItemClickListener and add

int n = mSpinner.getSelectedItemPosition();
mReadyListener.ready(n);
SpinnerDialog.this.dismiss();

as in the OnClickListener for the OK button. There's one caveat, though, and it's that the onclick listener does not fire if you reselect the default option. You need the OK button also.

Start with the layout:

res/layout/spinner_dialog.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content" 
  android:layout_height="wrap_content">
<TextView 
    android:id="@+id/dialog_label" 
    android:layout_height="wrap_content" 
    android:layout_width="fill_parent"
    android:hint="Please select an option" 
    />
<Spinner
    android:id="@+id/dialog_spinner" 
    android:layout_height="wrap_content" 
    android:layout_width="fill_parent"
    />
<Button
    android:id="@+id/dialogOK" 
    android:layout_width="120dp"
    android:layout_height="wrap_content" 
    android:text="OK"
    android:layout_below="@id/dialog_spinner"
    />
<Button
    android:id="@+id/dialogCancel" 
    android:layout_width="120dp"
    android:layout_height="wrap_content" 
    android:text="Cancel"
    android:layout_below="@id/dialog_spinner"
    android:layout_toRightOf="@id/dialogOK"
    />
</RelativeLayout>

Then, create the class:

src/your/package/SpinnerDialog.java:

public class SpinnerDialog extends Dialog {
    private ArrayList<String> mList;
    private Context mContext;
    private Spinner mSpinner;

   public interface DialogListener {
        public void ready(int n);
        public void cancelled();
    }

    private DialogListener mReadyListener;

    public SpinnerDialog(Context context, ArrayList<String> list, DialogListener readyListener) {
        super(context);
        mReadyListener = readyListener;
        mContext = context;
        mList = new ArrayList<String>();
        mList = list;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.spinner_dialog);
        mSpinner = (Spinner) findViewById (R.id.dialog_spinner);
        ArrayAdapter<String> adapter = new ArrayAdapter<String> (mContext, android.R.layout.simple_spinner_dropdown_item, mList);
        mSpinner.setAdapter(adapter);

        Button buttonOK = (Button) findViewById(R.id.dialogOK);
        Button buttonCancel = (Button) findViewById(R.id.dialogCancel);
        buttonOK.setOnClickListener(new android.view.View.OnClickListener(){
            public void onClick(View v) {
                int n = mSpinner.getSelectedItemPosition();
                mReadyListener.ready(n);
                SpinnerDialog.this.dismiss();
            }
        });
        buttonCancel.setOnClickListener(new android.view.View.OnClickListener(){
            public void onClick(View v) {
                mReadyListener.cancelled();
                SpinnerDialog.this.dismiss();
            }
        });
    }
}

Finally, use it as:

mSpinnerDialog = new SpinnerDialog(this, mTimers, new SpinnerDialog.DialogListener() {
  public void cancelled() {
    // do your code here
  }
  public void ready(int n) {
    // do your code here
  }
});

Adding this since this was not mentioned.

SELECT * FROM `la_schedule` WHERE date(start_date) > date('2012-11-18');

Because that's what actually works for me. Adding date() function on both comparison values.

I was doing a live search solution and needed to cancel pending requests that may have taken longer than the latest/most current request.

In my case I used something like this:

//On document ready
var ajax_inprocess = false;

$(document).ajaxStart(function() {
ajax_inprocess = true;
});

$(document).ajaxStop(function() {
ajax_inprocess = false;
});

//Snippet from live search function
if (ajax_inprocess == true)
{
    request.abort();
}
//Call for new request 

Difference Between ClassNotFoundException Vs NoClassDefFoundError

If you are using Angular UI Bootstrap, you can use tooltip with html syntax: tooltip-html-unsafe

e.g. update to angular 1.2.10 & angular-ui-bootstrap 0.11: http://jsfiddle.net/aX2vR/1/

old one: http://jsfiddle.net/8LMwz/1/

Yes, you can. That should work.

• . = any char except newline
• \. = the actual dot character
• .? = .{0,1} = match any char except newline zero or one times
• .* = .{0,} = match any char except newline zero or more times
• .+ = .{1,} = match any char except newline one or more times

The following takes any valid datetime value and returns the number of days in the associated month... it eliminates the ambiguity of both other answers...

 // pass in any date as parameter anyDateInMonth
function daysInMonth(anyDateInMonth) {
    return new Date(anyDateInMonth.getFullYear(), 
                    anyDateInMonth.getMonth()+1, 
                    0).getDate();}

1> $a = "This", "Is", "a", "cat"

2> [system.String]::Join(" ", $a)

Line two performs the operation and outputs to host, but does not modify $a:

3> $a = [system.String]::Join(" ", $a)

4> $a

This Is a cat

5> $a.Count

1

I solved the problem REF

Run

# For Yarn
yarn add eslint-plugin-jest -D

# For NPM
npm i eslint-plugin-jest -D

And then add in your .eslintrc file

{
    "extends": ["airbnb","plugin:jest/recommended"],
}

use this on:

$('body').on('focus',".datumwaehlen", function(){
    $(this).datepicker({
        minDate: -20
    });
});

You can also do this

[Flags]
public enum MyEnum
{
    None   = 0,
    First  = 1 << 0,
    Second = 1 << 1,
    Third  = 1 << 2,
    Fourth = 1 << 3
}

I find the bit-shifting easier than typing 4,8,16,32 and so on. It has no impact on your code because it's all done at compile time

I wrote a clean functional method of playing sounds:

sounds = {
    test : new Audio('/assets/sounds/test.mp3')
};

sound_volume = 0.1;

function playSound(sound) {
    sounds[sound].volume = sound_volume;
    sounds[sound].play();
}
function stopSound(sound) {
    sounds[sound].pause();
}
function setVolume(sound, volume) {
    sounds[sound].volume = volume;
    sound_volume = volume;
}

@ram's answer was really helpful. Here's a Swift version of the answer.

Swift 2

private func rotateImageView() {

    UIView.animateWithDuration(1, delay: 0, options: UIViewAnimationOptions.CurveLinear, animations: { () -> Void in
        self.imageView.transform = CGAffineTransformRotate(self.imageView.transform, CGFloat(M_PI_2))
        }) { (finished) -> Void in
            if finished {
                self.rotateImageView()
            }
    }
}

Swift 3,4,5

private func rotateImageView() {

    UIView.animate(withDuration: 1, delay: 0, options: UIView.AnimationOptions.curveLinear, animations: { () -> Void in
        self.imageView.transform = self.imageView.transform.rotated(by: .pi / 2)
    }) { (finished) -> Void in
        if finished {
            self.rotateImageView()
        }
    }
}

foo = {'a':1, 'b':2, 'c':3, 'd':4, 'e':5, 'f':6}
iterator = iter(foo.items())
for i in range(3):
    print(next(iterator))

Basically, turn the view (dict_items) into an iterator, and then iterate it with next().

you can use ES6 back quits

  var inputs = [_x000D_
        `<input type='checkbox' id='chbox0' onclick='checkboxChecked(this);'> <input  type='text' class='noteinputs0'id='note` + 0 + `' placeholder='task0'><button  id='notebtn0'                     >creat</button>`, `<input type='text' class='noteinputs' id='note` + 1 + `' placeholder='task1'><button  class='notebuttons' id='notebtn1' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 2 + `' placeholder='task2'><button  class='notebuttons' id='notebtn2' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 3 + `' placeholder='task3'><button  class='notebuttons' id='notebtn3' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 4 + `' placeholder='task4'><button  class='notebuttons' id='notebtn4' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 5 + `' placeholder='task5'><button  class='notebuttons' id='notebtn5' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 6 + `' placeholder='task6'><button  class='notebuttons' id='notebtn6' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 7 + `' placeholder='task7'><button  class='notebuttons' id='notebtn7' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 8 + `' placeholder='task8'><button  class='notebuttons' id='notebtn8' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 9 + `' placeholder='task9'><button  class='notebuttons' id='notebtn9' >creat</button>`_x000D_
    ].sort().join(" ");_x000D_
   document.querySelector('#hi').innerHTML += `<br>` +inputs;

<div id="hi"></div>

string[] lines = File.ReadAllLines(txtProxyListPath.Text);

// No need for the list
// List<string> list_lines = new List<string>(lines); 

Parallel.ForEach(lines, line =>
{
    //My Stuff
});

This will cause the lines to be parsed in parallel, within the loop. If you want a more detailed, less "reference oriented" introduction to the Parallel class, I wrote a series on the TPL which includes a section on Parallel.ForEach.

If you look at the scope of the variable 'hoursWorked' you will see that it is a member of the class (declared as private int)

The two variables you are having trouble with are passed as parameters to the constructor.

The error message is because 'hours' is out of scope in the setter.

Why not just use:

File file = new File("test.txt");

if (file.length() == 0) {
    // file empty
} else {
    // not empty
}

Is there something wrong with it?

var byteCharacters = atob(response.data);
var byteNumbers = new Array(byteCharacters.length);
for (var i = 0; i < byteCharacters.length; i++) {
  byteNumbers[i] = byteCharacters.charCodeAt(i);
}
var byteArray = new Uint8Array(byteNumbers);
var file = new Blob([byteArray], { type: 'application/pdf;base64' });
var fileURL = URL.createObjectURL(file);
window.open(fileURL);

You return a base64 string from the API or another source. You can also download it.

To elaborate on what @Raynos said, the function you have defined is an asynchronous callback. It doesn't execute right away, rather it executes when the file loading has completed. When you call readFile, control is returned immediately and the next line of code is executed. So when you call console.log, your callback has not yet been invoked, and this content has not yet been set. Welcome to asynchronous programming.

Example approaches

const fs = require('fs');
// First I want to read the file
fs.readFile('./Index.html', function read(err, data) {
    if (err) {
        throw err;
    }
    const content = data;

    // Invoke the next step here however you like
    console.log(content);   // Put all of the code here (not the best solution)
    processFile(content);   // Or put the next step in a function and invoke it
});

function processFile(content) {
    console.log(content);
}

Or better yet, as Raynos example shows, wrap your call in a function and pass in your own callbacks. (Apparently this is better practice) I think getting into the habit of wrapping your async calls in function that takes a callback will save you a lot of trouble and messy code.

function doSomething (callback) {
    // any async callback invokes callback with response
}

doSomething (function doSomethingAfter(err, result) {
    // process the async result
});

Sometimes file names are numbered, where the index may be at the beginning or the end. So I wanted to shorten from the center of the string:

function stringTruncateFromCenter(str, maxLength) {
    const midChar = "…";      // character to insert into the center of the result
    var left, right;

    if (str.length <= maxLength) return str;

    // length of beginning part      
    left = Math.ceil(maxLength / 2);

    // start index of ending part   
    right = str.length - Math.floor(maxLength / 2) + 1;   

    return str.substr(0, left) + midChar + str.substring(right);
}

Be aware that I used a fill character here with more than 1 byte in UTF-8.

Please use regex to remove anything before |

example

dsfdf | fdfsfsf
dsdss|gfghhghg
dsdsds |dfdsfsds

Use find and replace in notepad++

find: .+(\|) replace: \1

output

| fdfsfsf
|gfghhghg
|dfdsfsds

Say you naively wrote a student creation method like this:

void createStudent(String name) {
    database.execute("INSERT INTO students (name) VALUES ('" + name + "')");
}

And someone enters the name Robert'); DROP TABLE STUDENTS; --

What gets run on the database is this query:

INSERT INTO students (name) VALUES ('Robert'); DROP TABLE STUDENTS --')

The semicolon ends the insert command and starts another; the -- comments out the rest of the line. The DROP TABLE command is executed...

This is why bind parameters are a good thing.

I've been using this function for a while. Removes pretty much any messy html you can throw at it and leaves the text intact.

        private static readonly Regex _tags_ = new Regex(@"<[^>]+?>", RegexOptions.Multiline | RegexOptions.Compiled);

        //add characters that are should not be removed to this regex

            html = HttpUtility.HtmlDecode(html);

            html = RemoveTag(html, "<!--", "-->");
            html = RemoveTag(html, "<script", "</script>");
            html = RemoveTag(html, "<style", "</style>");

            //replace matches of these regexes with space
            html = _tags_.Replace(html, " ");
            html = _notOkCharacter_.Replace(html, " ");
            html = SingleSpacedTrim(html);

            return html;
        }

        private static String RemoveTag(String html, String startTag, String endTag)

                Int32 startTagPos = html.IndexOf(startTag, 0, StringComparison.CurrentCultureIgnoreCase);

                    continue;
                Int32 endTagPos = html.IndexOf(endTag, startTagPos + 1, StringComparison.CurrentCultureIgnoreCase);

                    continue;
                html = html.Remove(startTagPos, endTagPos - startTagPos + endTag.Length);
                bAgain = true;
            } while (bAgain);
            return html;
        }

        private static String SingleSpacedTrim(String inString)
        {

            {
                switch (c)
                {
                    case '\r':
                    case '\n':
                    case '\t':
                    case ' ':
                        if (!inBlanks)
                        {
                            inBlanks = true;
                            sb.Append(' ');
                        }   
                        continue;
                    default:
                        inBlanks = false;

Some of these answers do work, but setting position: absolute; and z-index: 10; seemed pretty strong just to achieve the required effect. I found the following was all that was required, though unfortunately, I've not been able to reduce it any further.

HTML:

<div class="wrapper">
    <div class="parent">
        <div class="child">
            ...
        </div>
    </div>
</div>

CSS:

.wrapper {
    position: relative;
    z-index: 0;
}

.child {
    position: relative;
    z-index: -1;
}

I used this technique to achieve a bordered hover effect for image links. There's a bit more code here but it uses the concept above to show the border over the top of the image.

As you mentioned in a comment, you're using log4j. I discovered (inadvertently) a place where I had written

LOG.error(exc);

instead of the typical

LOG.error("Some informative message", e);

through laziness or perhaps just not thinking about it. The unfortunate part of this is that it doesn't behave as you expect. The logger API actually takes Object as the first argument, not a string - and then it calls toString() on the argument. So instead of getting the nice pretty stack trace, it just prints out the toString - which in the case of NPE is pretty useless.

Perhaps this is what you're experiencing?

Try doing this, there's no special character to concatenate in bash :

mystring="${arg1}12${arg2}endoffile"

explanations

If you don't put brackets, you will ask bash to concatenate $arg112 + $argendoffile (I guess that's not what you asked) like in the following example :

mystring="$arg112$arg2endoffile"

The brackets are delimiters for the variables when needed. When not needed, you can use it or not.

another solution

$ arg1=foo
$ arg2=bar
$ mystring="$arg1"

You can pass any number of arguments to the function that apply is calling through either unnamed arguments, passed as a tuple to the args parameter, or through other keyword arguments internally captured as a dictionary by the kwds parameter.

For instance, let's build a function that returns True for values between 3 and 6, and False otherwise.

s = pd.Series(np.random.randint(0,10, 10))
s

0    5
1    3
2    1
3    1
4    6
5    0
6    3
7    4
8    9
9    6
dtype: int64

s.apply(lambda x: x >= 3 and x <= 6)

0     True
1     True
2    False
3    False
4     True
5    False
6     True
7     True
8    False
9     True
dtype: bool

This anonymous function isn't very flexible. Let's create a normal function with two arguments to control the min and max values we want in our Series.

def between(x, low, high):
    return x >= low and x =< high

We can replicate the output of the first function by passing unnamed arguments to args:

s.apply(between, args=(3,6))

Or we can use the named arguments

s.apply(between, low=3, high=6)

Or even a combination of both

s.apply(between, args=(3,), high=6)

Using http://blog.trolieb.com/trouble-multidimensional-arrays-swift/ as a start, I added generics to mine:

class Array2DTyped<T>{

var cols:Int, rows:Int
var matrix:[T]

init(cols:Int, rows:Int, defaultValue:T){
    self.cols = cols
    self.rows = rows
    matrix = Array(count:cols*rows,repeatedValue:defaultValue)
}

subscript(col:Int, row:Int) -> T {
    get{
        return matrix[cols * row + col]
    }
    set{
        matrix[cols * row + col] = newValue
    }
}

func colCount() -> Int {
    return self.cols
}

func rowCount() -> Int {
    return self.rows
}
}

I ran into the same issue and couldn't decide between laughing or smashing my head on the table when I read this error...

What git really tries to tell you: "You are already in a merge state and need to resolve the conflicts there first!"

You tried a merge and a conflict occured. Then, git stays in the merge state and if you want to resolve the merge with other commands git thinks you want to execute a new merge and so it tells you you can't do this because of your current unmerged files...

You can leave this state with git merge --abort and now try to execute other commands.

In my case I tried a pull and wanted to resolve the conflicts by hand when the error occured...

A limit on the number of open sockets is configurable in the /proc file system

cat /proc/sys/fs/file-max

Max for incoming connections in the OS defined by integer limits.

Linux itself allows billions of open sockets.

To use the sockets you need an application listening, e.g. a web server, and that will use a certain amount of RAM per socket.

RAM and CPU will introduce the real limits. (modern 2017, think millions not billions)

1 millions is possible, not easy. Expect to use X Gigabytes of RAM to manage 1 million sockets.

Outgoing TCP connections are limited by port numbers ~65000 per IP. You can have multiple IP addresses, but not unlimited IP addresses. This is a limit in TCP not Linux.

One other easy way of doing it would be as follows (if you have a simple NetBeans project and not using maven for example).

1. In Eclipse, Go to File -> New -> Java Project
2. Give a name for your project and click finish to create your project
3. When the project is created find the source folder in NetBeans project, drag and drop all the source files from the NetBeans project to 'src' folder of your new created project in eclipse.
4. Move the java source files to respective package (if required)
5. Now you should be able to run your NetBeans project in Eclipse.

You can also change the date format for the session. This is useful, for example, in Perl DBI, where the to_date() function is not available:

ALTER SESSION SET NLS_DATE_FORMAT='YYYY-MM-DD'

You can permanently set the default nls_date_format as well:

ALTER SYSTEM SET NLS_DATE_FORMAT='YYYY-MM-DD'

In Perl DBI you can run these commands with the do() method:

$db->do("ALTER SESSION SET NLS_DATE_FORMAT='YYYY-MM-DD');

For...in loop

The for...in loop improves upon the weaknesses of the for loop by eliminating the counting logic and exit condition.

Example:

const digits = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];

for (const index in digits) {
  console.log(digits[index]);
}

But, you still have to deal with the issue of using an index to access the values of the array, and that stinks; it almost makes it more confusing than before.

Also, the for...in loop can get you into big trouble when you need to add an extra method to an array (or another object). Because for...in loops loop over all enumerable properties, this means if you add any additional properties to the array's prototype, then those properties will also appear in the loop.

Array.prototype.decimalfy = function() {
  for (let i = 0; i < this.length; i++) {
    this[i] = this[i].toFixed(2);
  }
};

const digits = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];

for (const index in digits) {
  console.log(digits[index]);
}

Prints:

0

1

2

3

4

5

6

7

8

9

function() { for (let i = 0; i < this.length; i++) { this[i] = this[i].toFixed(2); } }

This is why for...in loops are discouraged when looping over arrays.

NOTE: The forEach loop is another type of for loop in JavaScript. However, forEach() is actually an array method, so it can only be used exclusively with arrays. There is also no way to stop or break a forEach loop. If you need that type of behavior in your loop, you’ll have to use a basic for loop.

For...of loop

The for...of loop is used to loop over any type of data that is iterable.

Example:

const digits = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];

for (const digit of digits) {
  console.log(digit);
}

Prints:

0

1

2

3

4

5

6

7

8

9

This makes the for...of loop the most concise version of all the for loops.

But wait, there’s more! The for...of loop also has some additional benefits that fix the weaknesses of the for and for...in loops.

You can stop or break a for...of loop at anytime.

const digits = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];

for (const digit of digits) {
  if (digit % 2 === 0) {
    continue;
  }
  console.log(digit);
}

Prints:

1

3

5

7

9

And you don’t have to worry about adding new properties to objects. The for...of loop will only loop over the values in the object.

Edit : See jme's answer for the best way with Python3.

Using pathlib, you have the following solution :

Let's say we want to check if son is a descendant of parent, and both are Path objects. We can get a list of the parts in the path with list(parent.parts). Then, we just check that the begining of the son is equal to the list of segments of the parent.

>>> lparent = list(parent.parts)
>>> lson = list(son.parts)
>>> if lson[:len(lparent)] == lparent:
>>> ... #parent is a parent of son :)

If you want to get the remaining part, you can just do

>>> ''.join(lson[len(lparent):])

It's a string, but you can of course use it as a constructor of an other Path object.

https://anzeljg.github.io/rin2/book2/2405/docs/tkinter/universal.html

w.winfo_children()
Returns a list of all w's children, in their stacking order from lowest (bottom) to highest (top).

for widget in frame.winfo_children():
    widget.destroy()

Will destroy all the widget in your frame. No need for a second frame.

This syntax is from the Visual Basic Select...Case Statement:

Dim number As Integer = 8
Select Case number
    Case 1 To 5
        Debug.WriteLine("Between 1 and 5, inclusive")
        ' The following is the only Case clause that evaluates to True.
    Case 6, 7, 8
        Debug.WriteLine("Between 6 and 8, inclusive")
    Case Is < 1
        Debug.WriteLine("Equal to 9 or 10")
    Case Else
        Debug.WriteLine("Not between 1 and 10, inclusive")
End Select

You cannot use this syntax in C#. Instead, you must use the syntax from your first example.

My advice is to make a big view model:

public BigViewModel
{
    public LoginViewModel LoginViewModel{get; set;}
    public RegisterViewModel RegisterViewModel {get; set;}
}

In your Index.cshtml, if for example you have 2 partials:

@addTagHelper *,Microsoft.AspNetCore.Mvc.TagHelpers
@model .BigViewModel

@await Html.PartialAsync("_LoginViewPartial", Model.LoginViewModel)

@await Html.PartialAsync("_RegisterViewPartial ", Model.RegisterViewModel )

and in controller:

model=new BigViewModel();
model.LoginViewModel=new LoginViewModel();
model.RegisterViewModel=new RegisterViewModel(); 

It depends what is a use of those tables, but you might consider putting trigger on original table on insert and update. When insert or update is done, update the second table based on only one item from the original table. It will be quicker.

import nltk is Python syntax, and as such won't work in a shell script.

To test the version of nltk and scikit_learn, you can write a Python script and run it. Such a script may look like

import nltk
import sklearn

print('The nltk version is {}.'.format(nltk.__version__))
print('The scikit-learn version is {}.'.format(sklearn.__version__))

# The nltk version is 3.0.0.
# The scikit-learn version is 0.15.2.

Note that not all Python packages are guaranteed to have a __version__ attribute, so for some others it may fail, but for nltk and scikit-learn at least it will work.

I first tried the accepted answer by Mr Green, but I found my columns didn't align, that float:left seems very suspicious. When I went from no scollbar to scrollbar -- my table body shifted a few pixels and I lost alignment.

• Encoding --> convert to ANSI
• save

If you have access to apache bin directory you can use,

httpd -M to check loaded modules first.

After that simple directives like Options -Indexes or deny from all will solidify that .htaccess are working correctly.

Builtin getopts only parse short options (except in ksh93), but you can still add few lines of scripting to make getopts handles long options.

Here is a part of code found in http://www.uxora.com/unix/shell-script/22-handle-long-options-with-getopts

  #== set short options ==#
SCRIPT_OPTS=':fbF:B:-:h'
  #== set long options associated with short one ==#
typeset -A ARRAY_OPTS
ARRAY_OPTS=(
    [foo]=f
    [bar]=b
    [foobar]=F
    [barfoo]=B
    [help]=h
    [man]=h
)

  #== parse options ==#
while getopts ${SCRIPT_OPTS} OPTION ; do
    #== translate long options to short ==#
    if [[ "x$OPTION" == "x-" ]]; then
        LONG_OPTION=$OPTARG
        LONG_OPTARG=$(echo $LONG_OPTION | grep "=" | cut -d'=' -f2)
        LONG_OPTIND=-1
        [[ "x$LONG_OPTARG" = "x" ]] && LONG_OPTIND=$OPTIND || LONG_OPTION=$(echo $OPTARG | cut -d'=' -f1)
        [[ $LONG_OPTIND -ne -1 ]] && eval LONG_OPTARG="\$$LONG_OPTIND"
        OPTION=${ARRAY_OPTS[$LONG_OPTION]}
        [[ "x$OPTION" = "x" ]] &&  OPTION="?" OPTARG="-$LONG_OPTION"

        if [[ $( echo "${SCRIPT_OPTS}" | grep -c "${OPTION}:" ) -eq 1 ]]; then
            if [[ "x${LONG_OPTARG}" = "x" ]] || [[ "${LONG_OPTARG}" = -* ]]; then 
                OPTION=":" OPTARG="-$LONG_OPTION"
            else
                OPTARG="$LONG_OPTARG";
                if [[ $LONG_OPTIND -ne -1 ]]; then
                    [[ $OPTIND -le $Optnum ]] && OPTIND=$(( $OPTIND+1 ))
                    shift $OPTIND
                    OPTIND=1
                fi
            fi
        fi
    fi

    #== options follow by another option instead of argument ==#
    if [[ "x${OPTION}" != "x:" ]] && [[ "x${OPTION}" != "x?" ]] && [[ "${OPTARG}" = -* ]]; then 
        OPTARG="$OPTION" OPTION=":"
    fi

    #== manage options ==#
    case "$OPTION" in
        f  ) foo=1 bar=0                    ;;
        b  ) foo=0 bar=1                    ;;
        B  ) barfoo=${OPTARG}               ;;
        F  ) foobar=1 && foobar_name=${OPTARG} ;;
        h ) usagefull && exit 0 ;;
        : ) echo "${SCRIPT_NAME}: -$OPTARG: option requires an argument" >&2 && usage >&2 && exit 99 ;;
        ? ) echo "${SCRIPT_NAME}: -$OPTARG: unknown option" >&2 && usage >&2 && exit 99 ;;
    esac
done
shift $((${OPTIND} - 1))

Here is a test:

# Short options test
$ ./foobar_any_getopts.sh -bF "Hello world" -B 6 file1 file2
foo=0 bar=1
barfoo=6
foobar=1 foobar_name=Hello world
files=file1 file2

# Long and short options test
$ ./foobar_any_getopts.sh --bar -F Hello --barfoo 6 file1 file2
foo=0 bar=1
barfoo=6
foobar=1 foobar_name=Hello
files=file1 file2

Otherwise in recent Korn Shell ksh93, getopts can naturally parse long options and even display a man page alike. (See http://www.uxora.com/unix/shell-script/20-getopts-with-man-page-and-long-options)

Use ActivityCompat.startActivity() works API > 21.

    ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(activity, transitionImage, EXTRA_IMAGE);
    ActivityCompat.startActivity(activity, intent, options.toBundle());

It worked for me, but the exe4j can leave a signature when you double click the .exe application

You could create your own:

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.FocusEvent;
import java.awt.event.FocusListener;
import javax.swing.*;

public class Main {

  public static void main(String[] args) {

    final JFrame frame = new JFrame();

    frame.setLayout(new BorderLayout());

    final JTextField textFieldA = new HintTextField("A hint here");
    final JTextField textFieldB = new HintTextField("Another hint here");

    frame.add(textFieldA, BorderLayout.NORTH);
    frame.add(textFieldB, BorderLayout.CENTER);
    JButton btnGetText = new JButton("Get text");

    btnGetText.addActionListener(new ActionListener() {
      @Override
      public void actionPerformed(ActionEvent e) {
        String message = String.format("textFieldA='%s', textFieldB='%s'",
            textFieldA.getText(), textFieldB.getText());
        JOptionPane.showMessageDialog(frame, message);
      }
    });

    frame.add(btnGetText, BorderLayout.SOUTH);
    frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    frame.setVisible(true);
    frame.pack();
  }
}

class HintTextField extends JTextField implements FocusListener {

  private final String hint;
  private boolean showingHint;

  public HintTextField(final String hint) {
    super(hint);
    this.hint = hint;
    this.showingHint = true;
    super.addFocusListener(this);
  }

  @Override
  public void focusGained(FocusEvent e) {
    if(this.getText().isEmpty()) {
      super.setText("");
      showingHint = false;
    }
  }
  @Override
  public void focusLost(FocusEvent e) {
    if(this.getText().isEmpty()) {
      super.setText(hint);
      showingHint = true;
    }
  }

  @Override
  public String getText() {
    return showingHint ? "" : super.getText();
  }
}

If you're still on Java 1.5, replace the this.getText().isEmpty() with this.getText().length() == 0.

Both will generate the same columns when you run the migration. In rails console, you can see that this is the case:

:001 > Micropost
=> Micropost(id: integer, user_id: integer, created_at: datetime, updated_at: datetime)

The second command adds a belongs_to :user relationship in your Micropost model whereas the first does not. When this relationship is specified, ActiveRecord will assume that the foreign key is kept in the user_id column and it will use a model named User to instantiate the specific user.

The second command also adds an index on the new user_id column.

That's probably the C++ runtime library. Since it's a DLL it is not included in your program executable. Your friend can download those libraries from Microsoft.

For rails6, I was facing the same problem, as I was missing following files, once I added them, the issue resolved:

1. config/master.key
2. config/credentials.yml.enc

Make sure you have this files.!!!

A little bit late, but you can request a higher quote here: https://support.google.com/youtube/contact/yt_api_form

I had this issue caused by having an unexpected folder on disk (jspm_packages, no longer being used) which was not tracked by source control (and hidden from my IDE). This had a duplicate install of TypeScript in it, which caused the issues.

Bit of an edge case but leaving an answer here just in case someone else is hunting for this solution.

There are a few ways to pass the list of files returned by the find command to the cat command, though technically not all use piping, and none actually pipe directly to cat.

1. The simplest is to use backticks (`):

   cat `find [whatever]`
   

   This takes the output of find and effectively places it on the command line of cat. This doesn't work well if find has too much output (more than can fit on a command-line) or if the output has special characters (like spaces).

2. In some shells, including bash, one can use $() instead of backticks :

   cat $(find [whatever])
   

   This is less portable, but is nestable. Aside from that, it has pretty much the same caveats as backticks.

3. Because running other commands on what was found is a common use for find, find has an -exec action which executes a command for each file it finds:

   find [whatever] -exec cat {} \;
   

   The {} is a placeholder for the filename, and the \; marks the end of the command (It's possible to have other actions after -exec.)

   This will run cat once for every single file rather than running a single instance of cat passing it multiple filenames which can be inefficient and might not have the behavior you want for some commands (though it's fine for cat). The syntax is also a awkward to type -- you need to escape the semicolon because semicolon is special to the shell!

4. Some versions of find (most notably the GNU version) let you replace ; with + to use -exec's append mode to run fewer instances of cat:

   find [whatever] -exec cat {} +
   

   This will pass multiple filenames to each invocation of cat, which can be more efficient.

   Note that this is not guaranteed to use a single invocation, however. If the command line would be too long then the arguments are spread across multiple invocations of cat. For cat this is probably not a big deal, but for some other commands this may change the behavior in undesirable ways. On Linux systems, the command line length limit is quite large, so splitting into multiple invocations is quite rare compared to some other OSes.

5. The classic/portable approach is to use xargs:

   find [whatever] | xargs cat
   

   xargs runs the command specified (cat, in this case), and adds arguments based on what it reads from stdin. Just like -exec with +, this will break up the command-line if necessary. That is, if find produces too much output, it'll run cat multiple times. As mentioned in the section about -exec earlier, there are some commands where this splitting may result in different behavior. Note that using xargs like this has issues with spaces in filenames, as xargs just uses whitespace as a delimiter.

6. The most robust, portable, and efficient method also uses xargs:

   find [whatever] -print0 | xargs -0 cat
   

   The -print0 flag tells find to use \0 (null character) delimiters between filenames, and the -0 flag tells xargs to expect these \0 delimiters. This has pretty much identical behavior to the -exec...+ approach, though is more portable (but unfortunately more verbose).

Simple copy & paste example with subqueries, Note, that both queries should return 1 row:

select
(select sum(items_1) from items_table_1 where ...)
-
(select count(items_2) from items_table_1 where ...) 

as difference

USe this function for date comparison in javascript:

    function fn_DateCompare(DateA, DateB) {
      var a = new Date(DateA);
      var b = new Date(DateB);

      var msDateA = Date.UTC(a.getFullYear(), a.getMonth()+1, a.getDate());
      var msDateB = Date.UTC(b.getFullYear(), b.getMonth()+1, b.getDate());

      if (parseFloat(msDateA) < parseFloat(msDateB))
        return -1;  // less than
      else if (parseFloat(msDateA) == parseFloat(msDateB))
        return 0;  // equal
      else if (parseFloat(msDateA) > parseFloat(msDateB))
        return 1;  // greater than
      else
        return null;  // error
  }

For maven2 there isn't a way to do what you describe. For maven 3, there is. If you are using maven 3 please see another answer for this question

For maven 2 I'd recommend creating your own custom pom for the dependency that has your <exclusions>. For projects that need to use that dependency, set the dependency to your custom pom instead of the typical artifact. While that does not necessarily allow you exclude all transitive dependencies with a single <exclusion>, it does allow you only have to write your dependency once and all of your projects don't need to maintain unnecessary and long exclusion lists.

I'm surprised no one's mentioned this yet: CSS transitions.

You can natively transition a div's background image:

#some_div {
    background-image:url(image_1.jpg);
    -webkit-transition:background-image 0.5s;
    /* Other vendor-prefixed transition properties */
    transition:background-image 0.5s;
}

#some_div:hover {
    background-image:url(image_2.jpg);
}

This saves any kind of JavaScript or jQuery animation to fade an <img/>'s src.

More information about transitions on MDN.

You have it covered aside from using the wrong property. The scrollbar can be triggered with any property overflow, overflow-x, or overflow-y and each can be set to any of visible, hidden, scroll, auto, or inherit. You are currently looking at these two:

• auto - This value will look at the width and height of the box. If they are defined, it won't let the box expand past those boundaries. Instead (if the content exceeds those boundaries), it will create a scrollbar for either boundary (or both) that exceeds its length.

• scroll - This values forces a scrollbar, no matter what, even if the content does not exceed the boundary set. If the content doesn't need to be scrolled, the bar will appear as "disabled" or non-interactive.

If you always want the vertical scrollbar to appear:

You should use overflow-y: scroll. This forces a scrollbar to appear for the vertical axis whether or not it is needed. If you can't actually scroll the context, it will appear as a"disabled" scrollbar.

If you only want a scrollbar to appear if you can scroll the box:

Just use overflow: auto. Since your content by default just breaks to the next line when it cannot fit on the current line, a horizontal scrollbar won't be created (unless it's on an element that has word-wrapping disabled). For the vertical bar,it will allow the content to expand up to the height you have specified. If it exceeds that height, it will show a vertical scrollbar to view the rest of the content, but will not show a scrollbar if it does not exceed the height.

Have a look at content negotiation in the WebAPI. These (Part 1 & Part 2) wonderfully detailed and thorough blog posts explain how it works.

In short, you are right, and just need to set the Accept or Content-Type request headers. Given your Action isn't coded to return a specific format, you can set Accept: application/json.

i would recommend going to http://sourceforge.net/projects/py2exe/files/latest/download?source=files to download py2exe. Then make a python file named setup.py. Inside it, type

from distutils.core import setup
import py2exe
setup(console=['nameoffile.py'])

Save in your user folder Also save the file you want converted in that same folder

Run window's command prompt type in setup.py install py2exe

It should print many lines of code...

Next, open the dist folder.

Run the exe file.

If there are needed files for the program to work, move them to the folder

Copy/Send the dist folder to person.

Optional: Change the name of the dist folder

Hope it works!:)

I think the best solution is resize the images via script or locally and upload them again. Remember, you're forcing your viewers to download larger files than they need

This would be an other method (without using any loop!):

import numpy as np
list(np.float_(list_name))

Split it by space and take first part like below. Hope this will help you.

var d = '12/12/1955 12:00:00 AM';
d = d.split(' ')[0];
console.log(d);

You should also think about the order of the words to make the auto name completion easier.

A good practice: library name + module name + action + subject

If a part is not relevant just skip it, but at least a module name and an action always should be presented.

Examples:

• function name: os_task_set_prio, list_get_size, avg_get
• define (here usually no action part): OS_TASK_PRIO_MAX

Very fiddly and nothing else seemed to work

$('select[name$="dropdown"]').children().text("Mr").prop("selected", true);

worked for me.

you can do this:

<div class="picture1">&nbsp;</div>

and put this into your css file:

div.picture1 {
   width:100px; /*width of your image*/
   height:100px; /*height of your image*/
   background-image:url('yourimage.file');
   margin:0; /* If you want no margin */
   padding:0; /*if your want to padding */
}

otherwise, just use them as plain

The TypeError is happening because k is a list, since it is created using a slice from another list with the line k = list[0:j]. This should probably be something like k = ' '.join(list[0:j]), so you have a string instead.

In addition to this, your if statement is incorrect as noted by Jesse's answer, which should read if k not in d or if not k in d (I prefer the latter).

You are also clearing your dictionary on each iteration since you have d = {} inside of your for loop.

Note that you should also not be using list or file as variable names, since you will be masking builtins.

Here is how I would rewrite your code:

d = {}
with open("filename.txt", "r") as input_file:
    for line in input_file:
        fields = line.split()
        j = fields.index("x")
        k = " ".join(fields[:j])
        d.setdefault(k, []).append(" ".join(fields[j+1:]))

The dict.setdefault() method above replaces the if k not in d logic from your code.

I am surprised these have not been mentioned: but instead of using bare-bones rather manual process with json.org's little package, GSon and Jackson are much more convenient to use. So:

• GSON
• Jackson

So you can actually bind to your own POJOs, not some half-assed tree nodes or Lists and Maps. (and at least Jackson allows binding to such things too (perhaps GSON as well, not sure), JsonNode, Map, List, if you really want these instead of 'real' objects)

EDIT 19-MAR-2014:

Another new contender is Jackson jr library: it uses same fast Streaming parser/generator as Jackson (jackson-core), but data-binding part is tiny (50kB). Functionality is more limited (no annotations, just regular Java Beans), but performance-wise should be fast, and initialization (first-call) overhead very low as well. So it just might be good choice, especially for smaller apps.

stop your application...or stop your slave so no new rows are being added

create table <new table> like <old table>;
insert <new table> select * from <old table>;
truncate table  <old table>;
insert <old table> select * from <new table>;

restart your server or slave

The answer given above can't solve my problem.So I change async into false to get the alert message.

jQuery.ajax({
            type:"post",
            dataType:"json",
            async: false,
            url: myAjax.ajaxurl,
            data: {action: 'submit_data', info: info},
            success: function(data) {
                alert("Data was succesfully captured");
            },
        });

When your class implements Comparable, the compareTo method of the class is defining the "natural" ordering of that object. That method is contractually obligated (though not demanded) to be in line with other methods on that object, such as a 0 should always be returned for objects when the .equals() comparisons return true.

A Comparator is its own definition of how to compare two objects, and can be used to compare objects in a way that might not align with the natural ordering.

For example, Strings are generally compared alphabetically. Thus the "a".compareTo("b") would use alphabetical comparisons. If you wanted to compare Strings on length, you would need to write a custom comparator.

In short, there isn't much difference. They are both ends to similar means. In general implement comparable for natural order, (natural order definition is obviously open to interpretation), and write a comparator for other sorting or comparison needs.

for SQL > odd:

select * from id in(select id from employee where id%2=1)

for SQL > Even:

select * from id in(select id from employee where id%2=0).....f5

The way I solved my problem is to keep the count of the number of objects iterated over, so far. I wanted to iterate over a set using calls to an instance method. Since I knew the length of the set, and the number of items counted so far, I effectively had an hasNext method.

A simple version of my code:

class Iterator:
    # s is a string, say
    def __init__(self, s):
        self.s = set(list(s))
        self.done = False
        self.iter = iter(s)
        self.charCount = 0

    def next(self):
        if self.done:
            return None
        self.char = next(self.iter)
        self.charCount += 1
        self.done = (self.charCount < len(self.s))
        return self.char

    def hasMore(self):
        return not self.done

Of course, the example is a toy one, but you get the idea. This won't work in cases where there is no way to get the length of the iterable, like a generator etc.

Whoever wants UML deserves Rational Rose :)

You can use SimpleDateFormat to do it. You just have to know 2 things.

1. All dates are internally represented in UTC
2. .getTime() returns the number of milliseconds since 1970-01-01 00:00:00 UTC.

package se.wederbrand.milliseconds;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;

public class Main {        
    public static void main(String[] args) throws Exception {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
        sdf.setTimeZone(TimeZone.getTimeZone("UTC"));

        String inputString = "00:01:30.500";

        Date date = sdf.parse("1970-01-01 " + inputString);
        System.out.println("in milliseconds: " + date.getTime());        
    }
}

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

Counting lines is too tedious for me, but counting 'paragraphs' isn't so bad. '{' and '}' move the cursor to the first empty line before and after the cursor, respectively. Cursor moving operations can be combined with deletion, and several other answers used a similar approach (dd for a line, dG for the end of the document, etc.)
For example:

/* Lorem ipsum dolor sit amet, consectetur adipiscing elit. */

Lorem *ipsum(void) {
  return dolor(sit, amet);
}

If your cursor starts above the comment block, 'd}' deletes the comment block, and 'd2}' deletes both the comment block and the code block. If your cursor starts below the code block, 'd{' deletes the code, and 'd2{' deletes both. Of course, you can skip over one block by moving the cursor first: '{d{' or '}d}'.

If you're consistent with your whitespace, or you can count the paragraphs at a glance, this should work. The Vim help file has more cursor tricks if you're interested.

There are two different types of quotation marks in MySQL. You need to use ` for column names and ' for strings. Since you have used ' for the filename column the query parser got confused. Either remove the quotation marks around all column names, or change 'filename' to `filename`. Then it should work.

You can use JavaScript to do what you want:

if (document.addEventListener !== undefined) {
  // Not IE
  document.addEventListener('click', checkSelection, false);
} else {
  // IE
  document.attachEvent('onclick', checkSelection);
}

function checkSelection() {
    var sel = {};
    if (window.getSelection) {
        // Mozilla
        sel = window.getSelection();
    } else if (document.selection) {
        // IE
        sel = document.selection.createRange();
    }

    // Mozilla
    if (sel.rangeCount) {
        sel.removeAllRanges();
        return;
    }

    // IE
    if (sel.text > '') {
        document.selection.empty();
        return;
    }
}

Soap box: You really shouldn't be screwing with the client's user agent in this manner. If the client wants to select things on the document, then they should be able to select things on the document. It doesn't matter if you don't like the highlight color, because you aren't the one viewing the document.

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

@model IList<BlockedIPViewModel>

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

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

Alternatively you could use an editor template:

@model IEnumerable<BlockedIPViewModel>

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

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

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

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

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

this fix worked for me:

took the solution from here: http://blogs.msdn.com/b/brianhartman/archive/2009/10/13/gdi-updated-again.aspx

Another way of doing this which mostly uses the storyboard and easily allows you to have multiple text fields is:

@IBAction func resignKeyboard(sender: AnyObject) {
    sender.resignFirstResponder()
}

Connect all your text fields for that view controller to that action on the Did End On Exit event of each field.

plt.close() will close current instance.

plt.close(2) will close figure 2

plt.close(plot1) will close figure with instance plot1

plt.close('all') will close all fiures

Found here.

Remember that plt.show() is a blocking function, so in the example code you used above, plt.close() isn't being executed until the window is closed, which makes it redundant.

You can use plt.ion() at the beginning of your code to make it non-blocking, although this has other implications.

EXAMPLE

After our discussion in the comments, I've put together a bit of an example just to demonstrate how the plot functionality can be used.

Below I create a plot:

fig = plt.figure(figsize=plt.figaspect(0.75))
ax = fig.add_subplot(1, 1, 1)
....
par_plot, = plot(x_data,y_data, lw=2, color='red')

In this case, ax above is a handle to a pair of axes. Whenever I want to do something to these axes, I can change my current set of axes to this particular set by calling axes(ax).

par_plot is a handle to the line2D instance. This is called an artist. If I want to change a property of the line, like change the ydata, I can do so by referring to this handle.

I can also create a slider widget by doing the following:

axsliderA = axes([0.12, 0.85, 0.16, 0.075])
sA = Slider(axsliderA, 'A', -1, 1.0, valinit=0.5)
sA.on_changed(update)

The first line creates a new axes for the slider (called axsliderA), the second line creates a slider instance sA which is placed in the axes, and the third line specifies a function to call when the slider value changes (update).

My update function could look something like this:

def update(val):
    A = sA.val
    B = sB.val
    C = sC.val
    y_data = A*x_data*x_data + B*x_data + C
    par_plot.set_ydata(y_data)
    draw()

The par_plot.set_ydata(y_data) changes the ydata property of the Line2D object with the handle par_plot.

The draw() function updates the current set of axes.

Putting it all together:

from pylab import *
import matplotlib.pyplot as plt
import numpy

def update(val):
    A = sA.val
    B = sB.val
    C = sC.val
    y_data = A*x_data*x_data + B*x_data + C
    par_plot.set_ydata(y_data)
    draw()


x_data = numpy.arange(-100,100,0.1);

fig = plt.figure(figsize=plt.figaspect(0.75))
ax = fig.add_subplot(1, 1, 1)
subplots_adjust(top=0.8)

ax.set_xlim(-100, 100);
ax.set_ylim(-100, 100);
ax.set_xlabel('X')
ax.set_ylabel('Y')

axsliderA = axes([0.12, 0.85, 0.16, 0.075])
sA = Slider(axsliderA, 'A', -1, 1.0, valinit=0.5)
sA.on_changed(update)

axsliderB = axes([0.43, 0.85, 0.16, 0.075])
sB = Slider(axsliderB, 'B', -30, 30.0, valinit=2)
sB.on_changed(update)

axsliderC = axes([0.74, 0.85, 0.16, 0.075])
sC = Slider(axsliderC, 'C', -30, 30.0, valinit=1)
sC.on_changed(update)

axes(ax)
A = 1;
B = 2;
C = 1;
y_data = A*x_data*x_data + B*x_data + C;

par_plot, = plot(x_data,y_data, lw=2, color='red')

show()

A note about the above: When I run the application, the code runs sequentially right through (it stores the update function in memory, I think), until it hits show(), which is blocking. When you make a change to one of the sliders, it runs the update function from memory (I think?).

This is the reason why show() is implemented in the way it is, so that you can change values in the background by using functions to process the data.

The following will display all 3 buttons on the same line provided there is enough horizontal space to display them:

<button type="submit" class="msgBtn" onClick="return false;" >Save</button>
<button type="submit" class="msgBtn2" onClick="return false;">Publish</button>
<button class="msgBtnBack">Back</button>
// Note the lack of unnecessary divs, floats, etc. 

The only reason the buttons wouldn't display inline is if they have had display:block applied to them within your css.

As some mentioned in the comments, you can put the images in the public folder. This is also explained in the docs of Create-React-App: https://create-react-app.dev/docs/using-the-public-folder/

For windows8 right click my pc properties then click environment variables user variable or System variables >> new >> put variable name and path : like this C:\Program Files\nodejs Then ok now open cmd and type npm it will work

I could also just add that I knew everything about the syntax change between Python2.7 and Python3, and my code was correctly written as print("string") and even print(f"string")...

But after some time of debugging I realized that my bash script was calling python like:

python file_name.py

which had the effect of calling my python script by default using python2.7 which gave the error. So I changed my bash script to:

python3 file_name.py

which of coarse uses python3 to run the script which fixed the error.

Add list-style-position: inside to the ul element. (example)

The default value for the list-style-position property is outside.

ul {_x000D_
    text-align: center;_x000D_
    list-style-position: inside;_x000D_
}

<ul>_x000D_
    <li>one</li>_x000D_
    <li>two</li>_x000D_
    <li>three</li>_x000D_
</ul>

Another option (which yields slightly different results) would be to center the entire ul element:

.parent {_x000D_
  text-align: center;_x000D_
}_x000D_
.parent > ul {_x000D_
  display: inline-block;_x000D_
}

<div class="parent">_x000D_
  <ul>_x000D_
    <li>one</li>_x000D_
    <li>two</li>_x000D_
    <li>three</li>_x000D_
  </ul>_x000D_
</div>

Update: created a js fiddle here to see it live: http://jsfiddle.net/HFMvX/

I went through tons of google searches and didn't find anything satisfying. i like how passpack have done it so essentially reverse-engineered their approach, here we go:

function scorePassword(pass) {
    var score = 0;
    if (!pass)
        return score;

    // award every unique letter until 5 repetitions
    var letters = new Object();
    for (var i=0; i<pass.length; i++) {
        letters[pass[i]] = (letters[pass[i]] || 0) + 1;
        score += 5.0 / letters[pass[i]];
    }

    // bonus points for mixing it up
    var variations = {
        digits: /\d/.test(pass),
        lower: /[a-z]/.test(pass),
        upper: /[A-Z]/.test(pass),
        nonWords: /\W/.test(pass),
    }

    var variationCount = 0;
    for (var check in variations) {
        variationCount += (variations[check] == true) ? 1 : 0;
    }
    score += (variationCount - 1) * 10;

    return parseInt(score);
}

Good passwords start to score around 60 or so, here's function to translate that in words:

function checkPassStrength(pass) {
    var score = scorePassword(pass);
    if (score > 80)
        return "strong";
    if (score > 60)
        return "good";
    if (score >= 30)
        return "weak";

    return "";
}

you might want to tune this a bit but i found it working for me nicely

1. In Eclipse, click on Windows > Preferences, and then choose Maven in the left side.
2. Check the box "Download repository index updates on startup".
   • Optionally, check the boxes Download Artifact Sources and Download Artifact JavaDoc.
3. Click OK. The warning won't appear anymore.
4. Restart Eclipse.

As long as the macros in question are in the same workbook and you verify the names exist, you can call those macros from any other module by name, not by module.

So if in Module1 you had two macros Macro1 and Macro2 and in Module2 you had Macro3 and Macro 4, then in another macro you could call them all:

Sub MasterMacro()
    Call Macro1
    Call Macro2
    Call Macro3
    Call Macro4
End Sub

Sometimes you have loops becouse your type class have references to other classes and that classes have references to your type class, thus you have to select the parameters that you need exactly in the json string, like this code.

List<ROficina> oficinas = new List<ROficina>();
oficinas = /*list content*/;
var x = JsonConvert.SerializeObject(oficinas.Select(o => new
            {
                o.IdOficina,
                o.Nombre
            }));

you have workaround by setting background color instead of this missing icon. Here are the steps to follow:

• open relevant 'jquery-ui-x.-.x.css' file
• search for the missing file name in css file(eg: ui-bg_flat_75_ffffff_40x100.png")
• Remove/comment the line that calls this background image
• instead add the following line to replace the background color 'background-color: #ffffff'

That will probably work

Responding to the Forum Thread for the sake of completeness. Amazon has stopped using the the ECU - Elastic Compute Units and moved on to a vCPU based measure. So ignoring the ECU you pretty much can start comparing the EC2 Instances' sizes as CPU (Clock Speed), number of CPUs, RAM, storage etc.

Every instance families' instance configurations are published as number of vCPU and what is the physical processor. Detailed info and screenshot obstained from here http://aws.amazon.com/ec2/instance-types/#instance-type-matrix

If you create your own adapter, there is one notable abstract function:

public void registerDataSetObserver(DataSetObserver observer) {
    ...
}

You can use the given observers to notify the system to update:

private ArrayList<DataSetObserver> observers = new ArrayList<DataSetObserver>();

public void registerDataSetObserver(DataSetObserver observer) {
    observers.add(observer);
}
public void notifyDataSetChanged(){
    for (DataSetObserver observer: observers) {
        observer.onChanged();
    }
}

Though aren't you glad there are things like the SimpleAdapter and ArrayAdapter and you don't have to do all that?

You can use the HAVING clause.

SELECT * 
FROM tab_name
GROUP BY email_id
HAVING COUNT(*) = 1;

SQL Server Express does not come with profiler, but you can use SQL Server 2005/2008 Express Profiler instead.

Even though this thread is already dead, might i suggest a working solution for this very same problem i was facing. Here it is (date is a string in the format dd-mm-yyyy):

def validatedate(date):
    parts = date.strip().split('-')

    if len(parts) == 3 and False not in [x.isdigit() for x in parts]: 
        birth = datetime.date(int(parts[2]), int(parts[1]), int(parts[0]))
        today = datetime.date.today()

        b = (birth.year * 10000) + (birth.month * 100) + (birth.day)
        t = (today.year * 10000) + (today.month * 100) + (today.day)

        if (t - 18 * 10000) >= b:
            return True

    return False

If you are using the Google Chrome driver, you can use this very simple code (it worked for me):

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument("--headless")
driver = webdriver.Chrome('chromedriver2_win32/chromedriver.exe', options=chrome_options)
driver.get('https://www.anywebsite.com')

There are already many good answers to the part "what is uintptr_t data type". I will try to address the "what it can be used for?" part in this post.

Primarily for bitwise operations on pointers. Remember that in C++ one cannot perform bitwise operations on pointers. For reasons see Why can't you do bitwise operations on pointer in C, and is there a way around this?

Thus in order to do bitwise operations on pointers one would need to cast pointers to type unitpr_t and then perform bitwise operations.

Here is an example of a function that I just wrote to do bitwise exclusive or of 2 pointers to store in a XOR linked list so that we can traverse in both directions like a doubly linked list but without the penalty of storing 2 pointers in each node.

 template <typename T>
 T* xor_ptrs(T* t1, T* t2)
 {
     return reinterpret_cast<T*>(reinterpret_cast<uintptr_t>(t1)^reinterpret_cast<uintptr_t>(t2));
  }

to validate the email string you will need to write a regular expression to check it is in the correct form. there are plenty out on the web but be carefull as some can exclude what are actually legal addresses.

essentially it will look something like this

^((?>[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+\x20*|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*"\x20*)*(?<angle><))?((?!\.)(?>\.?[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+)+|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*")@(((?!-)[a-zA-Z\d\-]+(?<!-)\.)+[a-zA-Z]{2,}|\[(((?(?<!\[)\.)(25[0-5]|2[0-4]\d|[01]?\d?\d)){4}|[a-zA-Z\d\-]*[a-zA-Z\d]:((?=[\x01-\x7f])[^\\\[\]]|\\[\x01-\x7f])+)\])(?(angle)>)$

Actually checking if the email exists and doesn't bounce would mean sending an email and seeing what the result was. i.e. it bounced or it didn't. However it might not bounce for several hours or not at all and still not be a "real" email address. There are a number of services out there which purport to do this for you and would probably be paid for by you and quite frankly why bother to see if it is real?

It is good to check the user has not misspelt their email else they could enter it incorrectly, not realise it and then get hacked of with you for not replying. However if someone wants to add a bum email address there would be nothing to stop them creating it on hotmail or yahoo (or many other places) to gain the same end.

So do the regular expression and validate the structure but forget about validating against a service.

The code you have given, needs to be corrected. In form tag you have to enclosed the onClick attribute value in double quote:

"window.open('google.htm','','scrollbars=no,menubar=no,height=600,width=800,resizable=yes,toolbar=no,status=no');"

You also need to take care that first parameter of window.open should also be enclosed using quotes.

I'm blind, and have been programming for about 13 years on Windows, Mac, Linux and DOS, in languages from C/C++, Python, Java, C# and various smaller languages along the way. Though the original question was around configuring the environment, I think it's best answered by looking at how a blind person would use a computer.

Some people use a talking environment, such as T. V. Raman and the Emacspeak environment mentioned in other answers. The more common solution by far is to have a screen reader which runs in the background monitoring OS activity and alerting the user via synthetic speech or a physical braille display (generally showing somewhere from 20 to 80 characters at a time). This then means a blind person can use any accessible application.

So, I personally use Visual Studio 2008 these days, and run it with very few modifications. I turn off certain features like displaying errors as I type since I find this distracting. Prior to joining Microsoft all my development was done in a standard text editor like Notepad, so once again no customisations.

It is possible to configure a screen reader to announce indentation. I personally don't use this, since Visual Studio takes care of this, and C# uses braces. But this would be very important in a language like Python where whitespace matters. Finally, Emacspeak does make use of different voices/pitches to indicate different parts of syntax (keywords, comments, identifiers, etc).

Typically one would use one (or more) image tags, maybe in combination with setting div background images in css to act as the submit button. The actual submit would be done in javascript on the click event.

A tutorial on the subject.

You can submit your jsp page to servlet. For this use <form> tag.

And to redirect use:

response.sendRedirect("servleturl")

First of all there are functions for this. But if you prefer vars then your task can be done like this:

$ cmd=ls

$ $cmd # works
file  file2  test

$ cmd='ls | grep file'

$ $cmd # not works
ls: cannot access '|': No such file or directory
ls: cannot access 'grep': No such file or directory
 file

$ bash -c $cmd # works
file  file2  test

$ bash -c "$cmd" # also works
file
file2

$ bash <<< $cmd
file
file2

$ bash <<< "$cmd"
file
file2

Or via tmp file

$ tmp=$(mktemp)
$ echo "$cmd" > "$tmp"
$ chmod +x "$tmp"
$ "$tmp"
file
file2

$ rm "$tmp"

This is a one line to solve the complete original question:

params.select { |k,_| k[/choice/]}.values.join('\t')

But most the solutions above are solving a case where you need to know the keys ahead of time, using slice or simple regexp.

Here is another approach that works for simple and more complex use cases, that is swappable at runtime

data = {}
matcher = ->(key,value) { COMPLEX LOGIC HERE }
data.select(&matcher)

Now not only this allows for more complex logic on matching the keys or the values, but it is also easier to test, and you can swap the matching logic at runtime.

Ex to solve the original issue:

def some_method(hash, matcher) 
  hash.select(&matcher).values.join('\t')
end

params = { :irrelevant => "A String",
           :choice1 => "Oh look, another one",
           :choice2 => "Even more strings",
           :choice3 => "But wait",
           :irrelevant2 => "The last string" }

some_method(params, ->(k,_) { k[/choice/]}) # => "Oh look, another one\\tEven more strings\\tBut wait"
some_method(params, ->(_,v) { v[/string/]}) # => "Even more strings\\tThe last string"

import datetime

d1 = datetime.date(2008,8,15)
d2 = datetime.date(2008,9,15)
diff = d2 - d1
for i in range(diff.days + 1):
    print (d1 + datetime.timedelta(i)).isoformat()

Consider the hex() method of the bytes type on Python 3.5 and up:

>>> array_alpha = [ 133, 53, 234, 241 ]
>>> print(bytes(array_alpha).hex())
8535eaf1

EDIT: it's also much faster than hexlify (modified @falsetru's benchmarks above)

from timeit import timeit
N = 10000
print("bytearray + hexlify ->", timeit(
    'binascii.hexlify(data).decode("ascii")',
    setup='import binascii; data = bytearray(range(255))',
    number=N,
))
print("byte + hex          ->", timeit(
    'data.hex()',
    setup='data = bytes(range(255))',
    number=N,
))

Result:

bytearray + hexlify -> 0.011218150997592602
byte + hex          -> 0.005952142993919551

This builds on @charkit's accepted answer allowing either an Array of strings, or string to passed in as an argument.

if (typeof String.prototype.endsWith === 'undefined') {
    String.prototype.endsWith = function(suffix) {
        if (typeof suffix === 'String') {
            return this.indexOf(suffix, this.length - suffix.length) !== -1;
        }else if(suffix instanceof Array){
            return _.find(suffix, function(value){
                console.log(value, (this.indexOf(value, this.length - value.length) !== -1));
                return this.indexOf(value, this.length - value.length) !== -1;
            }, this);
        }
    };
}

This requires underscorejs - but can probably be adjusted to remove the underscore dependency.

There is no float type. Looks like you want float64. You could also use float32 if you only need a single-precision floating point value.

package main

import "fmt"

func main() {
    i := 5
    f := float64(i)
    fmt.Printf("f is %f\n", f)
}

Left joins in LINQ are possible with the DefaultIfEmpty() method. I don't have the exact syntax for your case though...

Actually I think if you just change pets to pets.DefaultIfEmpty() in the query it might work...

EDIT: I really shouldn't answer things when its late...

Have you tried this http://tools.android.com/preview-channel ? Download preview channel. After that, install ADT Preview.

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

On OSX (Yosemite), I was having the same issue. After trying several of the other answers, I changed the install directory files to be owned by me:

cd /Applications/android-sdk-mac_x86

chown -R *

Where is my user account.

The problem I had with doing the root install is that some files were ending up in the root account home directory and others in mine once I started using Android Studio.

Similar to the answer by @russian_spy :

<ul>
{% for choice in choices.items %} 
  <li>{{choice.0}} - {{choice.1}}</li>
{% endfor %}
</ul>

This might be suitable for breaking down more complex dictionaries.

I'm sure Wikipedia can explain it better than I can, but it is basically to do with the fact that if you added an extra day every four years we'd get ahead of the sun as its time to orbit the sun is less than 365.25 days so we compensate for this by not adding leap days on years that are not divisible by 400 eg 1900.

Hope that helps

Gwerder's solution wont work because hash = hmac.read(); happens before the stream is done being finalized. Thus AngraX's issues. Also the hmac.write statement is un-necessary in this example.

Instead do this:

var crypto    = require('crypto');
var hmac;
var algorithm = 'sha1';
var key       = 'abcdeg';
var text      = 'I love cupcakes';
var hash;

hmac = crypto.createHmac(algorithm, key);

// readout format:
hmac.setEncoding('hex');
//or also commonly: hmac.setEncoding('base64');

// callback is attached as listener to stream's finish event:
hmac.end(text, function () {
    hash = hmac.read();
    //...do something with the hash...
});

More formally, if you wish, the line

hmac.end(text, function () {

could be written

hmac.end(text, 'utf8', function () {

because in this example text is a utf string

If you know the width of the span you could just stuff in a left margin.

Try this:

.center { text-align: center}
div.center span { display: table; }

Add the "center: class to your .

If you want some spans centered, but not others, replace the "div.center span" in your style sheet to a class (e.g "center-span") and add that class to the span.

Don't forget that you can also have a TextBox within other controls other than container controls too. You can even add a TextBox to a PictureBox.

So you also need to check if

someControl.HasChildren = True

in any recursive function.

This is the result I had from a layout to test this code:

TextBox13   Parent = Panel5
TextBox12   Parent = Panel5
TextBox9   Parent = Panel2
TextBox8   Parent = Panel2
TextBox16   Parent = Panel6
TextBox15   Parent = Panel6
TextBox14   Parent = Panel6
TextBox10   Parent = Panel3
TextBox11   Parent = Panel4
TextBox7   Parent = Panel1
TextBox6   Parent = Panel1
TextBox5   Parent = Panel1
TextBox4   Parent = Form1
TextBox3   Parent = Form1
TextBox2   Parent = Form1
TextBox1   Parent = Form1
tbTest   Parent = myPicBox

Try this with one Button and one RichTextBox on a form.

Option Strict On
Option Explicit On
Option Infer Off

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim pb As New PictureBox
        pb.Name = "myPicBox"
        pb.BackColor = Color.Goldenrod
        pb.Size = New Size(100, 100)
        pb.Location = New Point(0, 0)
        Dim tb As New TextBox
        tb.Name = "tbTest"
        pb.Controls.Add(tb)
        Me.Controls.Add(pb)

        Dim textBoxList As New List(Of Control)
        textBoxList = GetAllControls(Of TextBox)(Me)

        Dim sb As New System.Text.StringBuilder
        For index As Integer = 0 To textBoxList.Count - 1
            sb.Append(textBoxList.Item(index).Name & "   Parent = " & textBoxList.Item(index).Parent.Name & System.Environment.NewLine)

Use this function:

function getScriptName()
{
    $filename = baseName($_SERVER['REQUEST_URI']);
    $ipos = strpos($filename, "?");
    if ( !($ipos === false) )   $filename = substr($filename, 0, $ipos);
    return $filename;
}

To be honest I still think the best explanation is the one about future and promises on the Wikipedia: http://en.wikipedia.org/wiki/Futures_and_promises

The basic idea is that you have a separate pool of threads that execute tasks asynchronously. When using it. The object does however make the promise that it will execute the operation at some time and give you the result when you request it. This means that it will block when you request the result and hasn't finished, but execute in the thread pool otherwise.

From there you can optimize things: some operations can be implemented async and you can optimize things like file IO and network communication by batching together subsequent requests and/or reordering them. I'm not sure if this is already in the task framework of Microsoft - but if it isn't that would be one of the first things I would add.

You can actually implement the future pattern sort-of with yields in C# 4.0. If you want to know how it works exactly, I can recommend this link that does a decent job: http://code.google.com/p/fracture/source/browse/trunk/Squared/TaskLib/ . However, if you start toying with it yourself, you will notice that you really need language support if you want to do all the cool things -- which is exactly what Microsoft did.

It means it’ll do nothing. It’s an attempt to have the link not ‘navigate’ anywhere. But it’s not the right way.

You should actually just return false in the onclick event, like so:

<a href="#" onclick="return false;">hello</a>

Typically it’s used if the link is doing some ‘JavaScript-y’ thing. Like posting an AJAX form, or swapping an image, or whatever. In that case you just make whatever function is being called return false.

To make your website completely awesome, however, generally you’ll include a link that does the same action, if the person browsing it chooses not to run JavaScript.

<a href="backup_page_displaying_image.aspx"
   onclick="return coolImageDisplayFunction();">hello</a>

This might be a simple solution to achieve this:

INSERT INTO funds (ID, date, price)
SELECT 23, DATE('2013-02-12'), 22.5
  FROM dual
 WHERE NOT EXISTS (SELECT 1 
                     FROM funds 
                    WHERE ID = 23
                      AND date = DATE('2013-02-12'));

p.s. alternatively (if ID a primary key):

 INSERT INTO funds (ID, date, price)
    VALUES (23, DATE('2013-02-12'), 22.5)
        ON DUPLICATE KEY UPDATE ID = 23; -- or whatever you need

see this Fiddle.

As @ashishduh mentioned above, using android:autoLink="phone is also a good solution. But this option comes with one drawback, it doesn't work with all phone number lengths. For instance, a phone number of 11 numbers won't work with this option. The solution is to prefix your phone numbers with the country code.

Example:

08034448845 won't work

but +2348034448845 will

I had a case of tapping and dragging actions and I found out that the dragging was calling scrollViewDidEndDecelerating

And the change offset manually with code ([_scrollView setContentOffset:contentOffset animated:YES];) was calling scrollViewDidEndScrollingAnimation.

//This delegate method is called when the dragging scrolling happens, but no when the     tapping
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    //do whatever you want to happen when the scroll is done
}

//This delegate method is called when the tapping scrolling happens, but no when the  dragging
-(void)scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView
{
     //do whatever you want to happen when the scroll is done
}

A generalization of coobird's answer's utility function for creating new HashSets:

public static <T> Set<T> newHashSet(T... objs) {
    Set<T> set = new HashSet<T>();
    for (T o : objs) {
        set.add(o);
    }
    return set;
}

scaler = MinMaxScaler()
scaler.fit(data)
print(scaler.transform(data))
