Using **kwargs and default values is easy. Sometimes, however, you shouldn't be using **kwargs in the first place.

In this case, we're not really making best use of **kwargs.

class ExampleClass( object ):
    def __init__(self, **kwargs):
        self.val = kwargs.get('val',"default1")
        self.val2 = kwargs.get('val2',"default2")

The above is a "why bother?" declaration. It is the same as

class ExampleClass( object ):
    def __init__(self, val="default1", val2="default2"):
        self.val = val
        self.val2 = val2

When you're using **kwargs, you mean that a keyword is not just optional, but conditional. There are more complex rules than simple default values.

When you're using **kwargs, you usually mean something more like the following, where simple defaults don't apply.

class ExampleClass( object ):
    def __init__(self, **kwargs):
        self.val = "default1"
        self.val2 = "default2"
        if "val" in kwargs:
            self.val = kwargs["val"]
            self.val2 = 2*self.val
        elif "val2" in kwargs:
            self.val2 = kwargs["val2"]
            self.val = self.val2 / 2
        else:
            raise TypeError( "must provide val= or val2= parameter values" )

Here's one of my favorite places to use the ** syntax as in Dave Webb's final example:

mynum = 1000
mystr = 'Hello World!'
print("{mystr} New-style formatting is {mynum}x more fun!".format(**locals()))

I'm not sure if it's terribly fast when compared to just using the names themselves, but it's a lot easier to type!

You can use **kwargs to let your functions take an arbitrary number of keyword arguments ("kwargs" means "keyword arguments"):

>>> def print_keyword_args(**kwargs):
...     # kwargs is a dict of the keyword args passed to the function
...     for key, value in kwargs.iteritems():
...         print "%s = %s" % (key, value)
... 
>>> print_keyword_args(first_name="John", last_name="Doe")
first_name = John
last_name = Doe

You can also use the **kwargs syntax when calling functions by constructing a dictionary of keyword arguments and passing it to your function:

>>> kwargs = {'first_name': 'Bobby', 'last_name': 'Smith'}
>>> print_keyword_args(**kwargs)
first_name = Bobby
last_name = Smith

The Python Tutorial contains a good explanation of how it works, along with some nice examples.

<--Update-->

For people using Python 3, instead of iteritems(), use items()

One shouldn't use set_yticklabels to change the fontsize, since this will also set the labels (i.e. it will replace any automatic formatter by a FixedFormatter), which is usually undesired. The easiest is to set the respective tick_params:

ax.tick_params(axis="x", labelsize=8)
ax.tick_params(axis="y", labelsize=20)

or

ax.tick_params(labelsize=8)

in case both axes shall have the same size.

Of course using the rcParams as in @tmdavison's answer is possible as well.

You want

if 'errormessage' in kwargs:
    print("found it")

To get the value of errormessage

if 'errormessage' in kwargs:
    print("errormessage equals " + kwargs.get("errormessage"))

In this way, kwargs is just another dict. Your first example, if kwargs['errormessage'], means "get the value associated with the key "errormessage" in kwargs, and then check its bool value". So if there's no such key, you'll get a KeyError.

Your second example, if errormessage in kwargs:, means "if kwargs contains the element named by "errormessage", and unless "errormessage" is the name of a variable, you'll get a NameError.

I should mention that dictionaries also have a method .get() which accepts a default parameter (itself defaulting to None), so that kwargs.get("errormessage") returns the value if that key exists and None otherwise (similarly kwargs.get("errormessage", 17) does what you might think it does). When you don't care about the difference between the key existing and having None as a value or the key not existing, this can be handy.

** operator would be helpful here.

** operator will unpack the dict elements and thus **{'type':'Event'} would be treated as type='Event'

func(**{'type':'Event'}) is same as func(type='Event') i.e the dict elements would be converted to the keyword arguments.

FYI

* will unpack the list elements and they would be treated as positional arguments.

func(*['one', 'two']) is same as func('one', 'two')

In angular v10 I did something like this, first created a master.scss file and included the following variables:

master.scss file:

$theme: blue;

$button_color: red;

$label_color: gray;

Then I imported the master.scss file in my style.scss at the top:

style.scss file:

@use './master' as m;

Make sure you import the master.scss at the top.

m is an alias for the namespace;

Use @use instead of @import according to the official docs below:

https://sass-lang.com/documentation/at-rules/import

Then in your styles.scss file you can use any variable which is defined in master.scss like below:

someClass {

   backgroud-color: m.$theme;

   color: m.$button_color;

}

Hope it 'll help...

Happy Coding :)

An empty static class is appropriate. Consider using several classes, so that you end up with good groups of related constants, and not one giant Globals.cs file.

Additionally, for some int constants, consider the notation:

[Flags]
enum Foo
{
}

As this allows for treating the values like flags.

I'm using this:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(myUrl);
System.Diagnostics.Stopwatch timer = new Stopwatch();

timer.Start();

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

statusCode = response.StatusCode.ToString();

response.Close();

timer.Stop();

Associative array in PHP actually considered as a dictionary.

An array in PHP is actually an ordered map. A map is a type that associates values to keys. it can be treated as an array, list (vector), hash table (an implementation of a map), dictionary, collection, stack, queue, and probably more.

<?php
$array = array(
    "foo" => "bar",
    "bar" => "foo",
);

// Using the short array syntax
$array = [
    "foo" => "bar",
    "bar" => "foo",
];
?>

An array is different than a dictionary in that arrays have both an index and a key. Dictionaries only have keys and no index.

MVC defaults to DenyGet to protect you against a very specific attack involving JSON requests to improve the liklihood that the implications of allowing HTTP GET exposure are considered in advance of allowing them to occur.

This is opposed to afterwards when it might be too late.

Note: If your action method does not return sensitive data, then it should be safe to allow the get.

Further reading from my Wrox ASP.NET MVC3 book

By default, the ASP.NET MVC framework does not allow you to respond to an HTTP GET request with a JSON payload. If you need to send JSON in response to a GET, you'll need to explicitly allow the behavior by using JsonRequestBehavior.AllowGet as the second parameter to the Json method. However, there is a chance a malicious user can gain access to the JSON payload through a process known as JSON Hijacking. You do not want to return sensitive information using JSON in a GET request. For more details, see Phil's post at http://haacked.com/archive/2009/06/24/json-hijacking.aspx/ or this SO post.

Related StackOverflow question

With most recents browsers (starting with Firefox 21, Chrome 27, or IE 10), this is no more a vulnerability.

I have also faced this problem. Finally I got a solution. Use this bellow code. Hope: problem will be solve.

void is a reserved JavaScript keyword. It evaluates the expression and always returns undefined.

To get the number of element in any iterable object, your goto method in Python is len() eg.

a = range(1000) # range
b = 'abcdefghijklmnopqrstuvwxyz' # string
c = [10, 20, 30] # List
d = (30, 40, 50, 60, 70) # tuple
e = {11, 21, 31, 41} # set

len() method can work on all the above data types because they are iterable i.e You can iterate over them.

all_var = [a, b, c, d, e] # All variables are stored to a list
for var in all_var:
    print(len(var))

Rough estimate of the len() method

def len(iterable, /):
    total = 0
    for i in iterable:
        total += 1
    return total

The method Socket.Available will immediately throw a SocketException if the remote system has disconnected/closed the connection.

The following CSS based solution works for me:

mine was strange... IntelliJ specific quirk.

I looked at my output classes and there was a folder:

x.y.z

instead of

x/y/z

but if you have certain options set in IntelliJ, in the navigator they will both look like x.y.z

so check your output folder if you're scratching your head

In the detached 'Tool Options' window, click on the red 'X' in the upper right corner to get rid of the window. Then on the main Gimp screen, click on 'Windows,' then 'Dockable Dialogs.' The first entry on its list will be 'Tool Options,' so click on that. Then, Tool Options will appear as a tab in the window on the right side of the screen, along with layers and undo history. Click and drag that tab over to the toolbox window on hte left and drop it inside. The tool options will again be docked in the toolbox.

The fully-qualified name is opbtained as follows:

How to delete only the content of file in python

There is several ways of set the logical size of a file to 0, depending how you access that file:

To empty an open file:

def deleteContent(pfile):
    pfile.seek(0)
    pfile.truncate()

To empty a open file whose file descriptor is known:

def deleteContent(fd):
    os.ftruncate(fd, 0)
    os.lseek(fd, 0, os.SEEK_SET)

To empty a closed file (whose name is known)

def deleteContent(fName):
    with open(fName, "w"):
        pass

I have a temporary file with some content [...] I need to reuse that file

That being said, in the general case it is probably not efficient nor desirable to reuse a temporary file. Unless you have very specific needs, you should think about using tempfile.TemporaryFile and a context manager to almost transparently create/use/delete your temporary files:

import tempfile

with tempfile.TemporaryFile() as temp:
     # do whatever you want with `temp`

# <- `tempfile` guarantees the file being both closed *and* deleted
#     on exit of the context manager

Current React Router Version 5.2.0

activeStyle is a default css property of NavLink component which is imported from react-router-dom

So that we can write our own custom css to make it active.In this example i made background transparent and text to be bold.And I store it on a constant named isActive

    import React from "react";
    import { NavLink} from "react-router-dom";

    function nav() {

          const isActive = {
            fontWeight: "bold",
            backgroundColor: "rgba(255, 255, 255, 0.1)",
          };
    
    return (
          <ul className="navbar-nav mr-auto">
            <li className="nav-item">
              <NavLink className="nav-link" to="/Shop" activeStyle={isActive}>
                Shop
              </NavLink>
            </li>
          </ul>
          );

    export default nav;

I am not sure when it was added, but I'm using v0.10.8 and Alt + Z is the keyboard shortcut for turning word wrap on and off. This satisfies the requirement of "able to turn it on and off quickly".

The setting does not persist after closing Visual Studio Code. To persist, you need to set it through Radha's answer of using the settings.json file...

// Place your settings in this file to overwrite the default settings
{ "editor.wrappingColumn": 0 }

To avoid remembering what you need to do each time you get the message:

Please specify which branch you want to merge with. See git-pull(1)
for details.
.....

You can use the following script which sets origin as upstream for the current branch you are in.

In my case I almost never set something else than origin as the default upstream. Also I almost always keep the same branch name for local and remote branch. So the following fits me:

#!/bin/bash
# scriptname: git-branch-set-originupstream
current_branch="$(git branch | grep -oP '(?<=^\* )(.*)$')"
upstream="origin/$current_branch"
git branch -u "$upstream"

In Windows 7, 8 or 8.1, in Devices Manager:

1. Select tree 'Android Device': remove 'Android Composite ADB Interface' [?]
2. Press on main root of devices tree and call context menu (by right mouse click) and click on 'Update configuration'
3. After updating your device should appear in 'Other devices'
4. Select your device, call context menu from it and choose 'Update driver' and perform this updating

You may use two options:

1. createElement
2. InnerHTML

Create Element is the fastest way (check here.):

$(document.createElement('table'));

InnerHTML is another popular approach:

$("#foo").append("<div>hello world</div>"); // Check similar for table too.

Check a real example on How to create a new table with rows using jQuery and wrap it inside div.

There may be other approaches as well. Please use this as a starting point and not as a copy-paste solution.

Edit:

Check Dynamic creation of table with DOM

Edit 2:

IMHO, you are mixing object and inner HTML. Let's try with a pure inner html approach:

function createProviderFormFields(id, labelText, tooltip, regex) {
    var tr = '<tr>' ;
         // create a new textInputBox  
           var textInputBox = '<input type="text" id="' + id + '" name="' + id + '" title="' + tooltip + '" />';  
        // create a new Label Text
            tr += '<td>' + labelText  + '</td>';
            tr += '<td>' + textInputBox + '</td>';  
    tr +='</tr>';
    return tr;
}

I faced this issue, and resolved this issue using getchar() to catch the ('\n') new char

Don't use opacity for this, set the background to an RGBA-value instead to only make the background semi-transparent. In your case it would be like this.

.content {
    padding:20px;
    width:710px;
    position:relative;
    background: rgb(204, 204, 204); /* Fallback for older browsers without RGBA-support */
    background: rgba(204, 204, 204, 0.5);
}

See http://css-tricks.com/rgba-browser-support/ for more info and samples of rgba-values in css.

The easiest way is to handle all of your database interactions in its own module that you export to your routes. If your route has no context of the database then SQL can't touch it anyway.

With Python 3, how about:

try:
    with open(filename, 'x') as tempfile: # OSError if file exists or is invalid
        pass
except OSError:
    # handle error here

With the 'x' option we also don't have to worry about race conditions. See documentation here.

Now, this WILL create a very shortlived temporary file if it does not exist already - unless the name is invalid. If you can live with that, it simplifies things a lot.

You can also convert by creating a dictionary of elements and then directly converting to a data frame:

import xml.etree.ElementTree as ET
import pandas as pd

# Contents of test.xml
# <?xml version="1.0" encoding="utf-8"?> <tags>   <row Id="1" TagName="bayesian" Count="4699" ExcerptPostId="20258" WikiPostId="20257" />   <row Id="2" TagName="prior" Count="598" ExcerptPostId="62158" WikiPostId="62157" />   <row Id="3" TagName="elicitation" Count="10" />   <row Id="5" TagName="open-source" Count="16" /> </tags>

root = ET.parse('test.xml').getroot()

tags = {"tags":[]}
for elem in root:
    tag = {}
    tag["Id"] = elem.attrib['Id']
    tag["TagName"] = elem.attrib['TagName']
    tag["Count"] = elem.attrib['Count']
    tags["tags"]. append(tag)

df_users = pd.DataFrame(tags["tags"])
df_users.head()

You can create your own extension method to do this:

public static bool Contains(this string source, string toCheck, StringComparison comp)
  {
    return source != null && toCheck != null && source.IndexOf(toCheck, comp) >= 0;
  }

And then call:

 mystring.Contains(myStringToCheck, StringComparison.OrdinalIgnoreCase);

is it helpful to you see the image

Now with new Xcode if the icon of the Xcode is on dock you can just right click it and form the menu you can select Open Developer Tool and in the sub menu you can select the iOS Simulator to open the simulator without opening the Xcode.!

List<String> items = new ArrayList<>();
items.add("A");
items.add("B");
items.add("C");
items.add("D");
items.add("E");

//lambda
//Output : A,B,C,D,E
items.forEach(item->System.out.println(item));

//Output : C
items.forEach(item->{
    System.out.println(item);
    System.out.println(item.toLowerCase());
  }
});

all solutions above doesn't work for me. but they give me some clues to fix this error.

The scalar formatter supports collecting the exponents. The docs are as follows:

class matplotlib.ticker.ScalarFormatter(useOffset=True, useMathText=False, useLocale=None) Bases: matplotlib.ticker.Formatter

Tick location is a plain old number. If useOffset==True and the data range is much smaller than the data average, then an offset will be determined such that the tick labels are meaningful. Scientific notation is used for data < 10^-n or data >= 10^m, where n and m are the power limits set using set_powerlimits((n,m)). The defaults for these are controlled by the axes.formatter.limits rc parameter.

your technique would be:

from matplotlib.ticker import ScalarFormatter
xfmt = ScalarFormatter()
xfmt.set_powerlimits((-3,3))  # Or whatever your limits are . . .
{{ Make your plot }}
gca().xaxis.set_major_formatter(xfmt)

To get the exponent displayed in the format x10^5, instantiate the ScalarFormatter with useMathText=True.

You could also use:

xfmt.set_useOffset(10000)

To get a result like this:

Notice that if and other looping/branching constructs are not listed - only classes, functions, and modules provide scope in Python, so anything declared in an if block has the same scope as anything decleared outside the block. Variables aren't checked at compile time, which is why other languages throw an exception. In python, so long as the variable exists at the time you require it, no exception will be thrown.

Thank you for advices. I had the same problem when concatenate several fields, but even xmlagg not helped me - I still got the ORA-01489. After several attempts I found the cause and solution:

1. Cause: one of fields in my xmlagg stores large text;
2. Solution: apply to_clob() function.

Example:

rtrim(xmlagg(xmlelement(t, t.field1 ||'|'|| 
                           t.field2 ||'|'|| 
                           t.field3 ||'|'|| 
                           to_clob(t.field4),'; ').extract('//text()')).GetClobVal(),',')

Hope this help anybody.

Put your domain name here: https://www.ssllabs.com/ssltest/analyze.html You should be able to see if there are any issues with your ssl certificate chain. I am guessing that you have SSL chain issues. A short description of the problem is that there's actually a list of certificates on your server (and not only one) and these need to be in the correct order. If they are there but not in the correct order, the website will be fine on desktop browsers (an iOs as well I think), but android is more strict about the order of certificates, and will give an error if the order is incorrect. To fix this you just need to re-order the certificates.

You could use a navigation property if its available. It produces an inner join in the SQL.

The .NET Framework includes the following three predefined IFormatProvider implementations to provide culture-specific information that is used in formatting or parsing numeric and date and time values:

1. The NumberFormatInfo class, which provides information that is used to format numbers, such as the currency, thousands separator, and decimal separator symbols for a particular culture. For information about the predefined format strings recognized by a NumberFormatInfo object and used in numeric formatting operations, see Standard Numeric Format Strings and Custom Numeric Format Strings.
2. The DateTimeFormatInfo class, which provides information that is used to format dates and times, such as the date and time separator symbols for a particular culture or the order and format of a date's year, month, and day components. For information about the predefined format strings recognized by a DateTimeFormatInfo object and used in numeric formatting operations, see Standard Date and Time Format Strings and Custom Date and Time Format Strings.
3. The CultureInfo class, which represents a particular culture. Its GetFormat method returns a culture-specific NumberFormatInfo or DateTimeFormatInfo object, depending on whether the CultureInfo object is used in a formatting or parsing operation that involves numbers or dates and times.

The .NET Framework also supports custom formatting. This typically involves the creation of a formatting class that implements both IFormatProvider and ICustomFormatter. An instance of this class is then passed as a parameter to a method that performs a custom formatting operation, such as String.Format(IFormatProvider, String, Object[]).

I have the same problem with spring 3.0.2 and spring-beans-3.0.xsd.

My solution:

Create a file META-INF/spring.schemas in the source folder and copy all necesary definitions. Create spring.handlers too.

I think that the class PluggableSchemaResolver is not working correctly.

http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/beans/factory/xml/PluggableSchemaResolver.html

from the javadoc:

"By default, this class will look for mapping files in the classpath using the pattern: META-INF/spring.schemas allowing for multiple files to exist on the classpath at any one time."

but in my case, this class only read the first spring.schemas finded.

To make them accessible from the web, you should create a symbolic link from public/storage to storage/app/public.

ln -s /path/to/laravel/storage/app/public /path/to/laravel/public/storage

Now you can create in your view an URL to the files using the asset helper:

echo asset('storage/file.txt');

if ("one" !== 1 )

would evaluate as true, the string "one" is not equal to the number 1

android:layout_gravity is used for the layout itself

Use android:gravity="center" for children of your LinearLayout

So your code should be:

<LinearLayout
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:layout_weight="1" >

You can set the state of the checkbox based on the value:

$('#your-checkbox').prop('checked', value == 1);

If you wanna do with a button click and not the other way. You can do it by adding location.href to your button. Here is how I'm using

<button class="btn btn-lg btn-primary" id="submit" onclick="location.href ='/dashboard'" >Go To Dashboard</button>

The button above uses bootstrap classes for styling. Without styling, the simplest code would be

<button onclick="location.href ='/dashboard'" >Go To Dashboard</button>

The /dashboard is my JSP page, If you are using extension too then used /dashboard.jsp

Use an HTML line break (<br />) to force a line break within a table cell:

|Something|Something else<br />that's rather long|Something else|

JavascriptExecutor jse = ((JavascriptExecutor) driver);
jse.executeScript("window.scrollTo(0, document.body.scrollHeight)");

This code works for me. As the page which I'm testing, loads as we scroll down.

According to the documentation, $lookup can join only one external collection.

What you could do is to combine userInfo and userRole in one collection, as provided example is based on relational DB schema. Mongo is noSQL database - and this require different approach for document management.

Please find below 2-step query, which combines userInfo with userRole - creating new temporary collection used in last query to display combined data. In last query there is an option to use $out and create new collection with merged data for later use.

create collections

db.sivaUser.insert(
{    
    "_id" : ObjectId("5684f3c454b1fd6926c324fd"),
        "email" : "[email protected]",
        "userId" : "AD",
        "userName" : "admin"
})

//"userinfo"
db.sivaUserInfo.insert(
{
    "_id" : ObjectId("56d82612b63f1c31cf906003"),
    "userId" : "AD",
    "phone" : "0000000000"
})

//"userrole"
db.sivaUserRole.insert(
{
    "_id" : ObjectId("56d82612b63f1c31cf906003"),
    "userId" : "AD",
    "role" : "admin"
})

"join" them all :-)

db.sivaUserInfo.aggregate([
    {$lookup:
        {
           from: "sivaUserRole",
           localField: "userId",
           foreignField: "userId",
           as: "userRole"
        }
    },
    {
        $unwind:"$userRole"
    },
    {
        $project:{
            "_id":1,
            "userId" : 1,
            "phone" : 1,
            "role" :"$userRole.role"
        }
    },
    {
        $out:"sivaUserTmp"
    }
])


db.sivaUserTmp.aggregate([
    {$lookup:
        {
           from: "sivaUser",
           localField: "userId",
           foreignField: "userId",
           as: "user"
        }
    },
    {
        $unwind:"$user"
    },
    {
        $project:{
            "_id":1,
            "userId" : 1,
            "phone" : 1,
            "role" :1,
            "email" : "$user.email",
            "userName" : "$user.userName"
        }
    }
])

First things is this is only for advanced developers persons Who all are now beginner to php dont use this function if you are using the huge project in core php use this function

function displayAllRecords($serverName, $userName, $password, $databaseName,$sqlQuery='')
{
    $databaseConnectionQuery =  mysqli_connect($serverName, $userName, $password, $databaseName);
    if($databaseConnectionQuery === false)
    {
        die("ERROR: Could not connect. " . mysqli_connect_error());
        return false;
    }

    $resultQuery = mysqli_query($databaseConnectionQuery,$sqlQuery);
    $fetchFields = mysqli_fetch_fields($resultQuery);
    $fetchValues = mysqli_fetch_fields($resultQuery);

    if (mysqli_num_rows($resultQuery) > 0) 
    {           

        echo "<table class='table'>";
        echo "<tr>";
        foreach ($fetchFields as $fetchedField)
         {          
            echo "<td>";
            echo "<b>" . $fetchedField->name . "<b></a>";
            echo "</td>";
        }       
        echo "</tr>";
        while($totalRows = mysqli_fetch_array($resultQuery)) 
        {           
            echo "<tr>";                                
            for($eachRecord = 0; $eachRecord < count($fetchValues);$eachRecord++)
            {           
                echo "<td>";
                echo $totalRows[$eachRecord];
                echo "</td>";               
            }
            echo "<td><a href=''><button>Edit</button></a></td>";
            echo "<td><a href=''><button>Delete</button></a></td>";
            echo "</tr>";           
        } 
        echo "</table>";        

    } 
    else
    {
      echo "No Records Found in";
    }
}

All set now Pass the arguments as For Example

$queryStatment = "SELECT * From USERS "; $testing = displayAllRecords('localhost','root','root@123','email',$queryStatment); echo $testing;

Here

localhost indicates Name of the host,

root indicates the username for database

root@123 indicates the password for the database

$queryStatment for generating Query

hope it helps

Create a separate JavaScript function that can be called to close the dialog using the specific object id, and place the function outside of $(document).ready() like this:

function closeDialogWindow() { 
$('#dialogWindow').dialog('close');
}

NOTE: The function must be declared outside of $(document).ready() so jQuery doesn't try to trigger the close event on the dialog before it is created in the DOM.

If you are using Spring boot and have this issue with the OffsetDateTime then need to use the registerModules as answered above by @greperror(answered May 28 '16 at 13:04) but note that there is one difference. The dependency mentioned doesn't need to be added as I am guessing that spring boot has it already. I was having this issue with Spring boot and it worked for me without adding this dependency.

You can use the Java8 syntax for CompletableFuture, this way you can perform additional async computations based on the result from calling an async function.

for example:

 CompletableFuture.supplyAsync(this::findSomeData)
                     .thenApply(this:: intReturningMethod)
                     .thenAccept(this::notify);

To make all 3: Model, Controller & Migration Schema of table

write in your console: php artisan make:model NameOfYourModel -mcr

int a[] = { 2, 6, 8, 5, 4, 3 }; 
int b[] = { 2, 3, 4, 7 };

if you take float number then you take float and it's your choice

this is very good way to show array elements.

If you're still stuck on PowerShell v1.0 or v2.0, here is my variation on Jason Stangroome's excellent answer.

Create a powershell4.cmd somewhere on your path with the following contents:

@echo off
:: http://stackoverflow.com/questions/7308586/using-batch-echo-with-special-characters
if exist %~dp0powershell.exe.activation_config goto :run
echo.^<?xml version="1.0" encoding="utf-8" ?^>                 > %~dp0powershell.exe.activation_config
echo.^<configuration^>                                        >> %~dp0powershell.exe.activation_config
echo.  ^<startup useLegacyV2RuntimeActivationPolicy="true"^>  >> %~dp0powershell.exe.activation_config
echo.    ^<supportedRuntime version="v4.0"/^>                 >> %~dp0powershell.exe.activation_config
echo.  ^</startup^>                                           >> %~dp0powershell.exe.activation_config
echo.^</configuration^>                                       >> %~dp0powershell.exe.activation_config
:run
:: point COMPLUS_ApplicationMigrationRuntimeActivationConfigPath to the directory that this cmd file lives in
:: and the directory contains a powershell.exe.activation_config file which matches the executable name powershell.exe
set COMPLUS_ApplicationMigrationRuntimeActivationConfigPath=%~dp0
%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe %*
set COMPLUS_ApplicationMigrationRuntimeActivationConfigPath=

This will allow you to launch an instance of the powershell console running under .NET 4.0.

You can see the difference on my system where I have PowerShell 2.0 by examining the output of the following two commands run from cmd.

C:\>powershell -ExecutionPolicy ByPass -Command $PSVersionTable

Just rename the .war into .jar and unzip it using Winrar (or any other archive manager).

Declare an empty SKSpriteNode, so there won't be needing for unwraping

var sprites = [SKSpriteNode](count: 64, repeatedValue: SKSpriteNode())

Try:

which( !is.na(p), arr.ind=TRUE)

Which I think is just as informative and probably more useful than the output you specified, But if you really wanted the list version, then this could be used:

> apply(p, 1, function(x) which(!is.na(x)) )
[[1]]
[1] 2 3

[[2]]
[1] 4 7

[[3]]
integer(0)

[[4]]
[1] 5

[[5]]
integer(0)

Or even with smushing together with paste:

lapply(apply(p, 1, function(x) which(!is.na(x)) ) , paste, collapse=", ")

The output from which function the suggested method delivers the row and column of non-zero (TRUE) locations of logical tests:

> which( !is.na(p), arr.ind=TRUE)
     row col
[1,]   1   2
[2,]   1   3
[3,]   2   4
[4,]   4   5
[5,]   2   7

Without the arr.ind parameter set to non-default TRUE, you only get the "vector location" determined using the column major ordering the R has as its convention. R-matrices are just "folded vectors".

> which( !is.na(p) )
[1]  6 11 17 24 32

Use the download attribute:

<a download='FileName' href='your_url'>

The download attribute works on Chrome, Firefox, Edge, Opera, desktop Safari 10+, iOS Safari 13+, and not IE11.

@Jon: Jon, are you saying using multiple where clauses e.g.

var query = from r in tempData.AsEnumerable()
            where r.Field<string>("UserName") != "XXXX" 
            where r.Field<string>("UserName") != "YYYY"
            select r;

is more restictive than using

var query = from r in tempData.AsEnumerable()
            where r.Field<string>("UserName") != "XXXX" && r.Field<string>("UserName") != "YYYY"
            select r;

I think they are equivalent as far as the result goes.

However, I haven't tested, if using multiple where in the first example cause in 2 subqueries, i.e. .Where(r=>r.UserName!="XXXX").Where(r=>r.UserName!="YYYY) or the LINQ translator is smart enought to execute .Where(r=>r.UserName!="XXXX" && r.UsernName!="YYYY")

Here an alternative to the one liner from jim, this time in a script

ARGV[0..-3].each{|f| File.write(f, File.read(f).gsub(ARGV[-2],ARGV[-1]))}

Save it in a script, eg replace.rb

You start in on the command line with

replace.rb *.txt <string_to_replace> <replacement>

*.txt can be replaced with another selection or with some filenames or paths

broken down so that I can explain what's happening but still executable

# ARGV is an array of the arguments passed to the script.
ARGV[0..-3].each do |f| # enumerate the arguments of this script from the first to the last (-1) minus 2
  File.write(f,  # open the argument (= filename) for writing
    File.read(f) # open the argument (= filename) for reading
    .gsub(ARGV[-2],ARGV[-1])) # and replace all occurances of the beforelast with the last argument (string)
end

EDIT: if you want to use a regular expression use this instead Obviously, this is only for handling relatively small text files, no Gigabyte monsters

ARGV[0..-3].each{|f| File.write(f, File.read(f).gsub(/#{ARGV[-2]}/,ARGV[-1]))}

You may try this CSS. I have experienced it working always.

div {
  border-style: solid;
  padding: 5px;
}

table {
  width: 100%;
  word-break: break-all;
  border-style: solid;
}

<div style="width:200px;">
  <table>
    <tr>
      <th>Col 1</th>
      <th>Col 2</th>
      <th>Col 3</th>
      <th>Col 4</th>
      <th>Col 5</th>
    </tr>
    <tr>
      <td>data 1</td>
      <td>data 2</td>
      <td>data 3</td>
      <td>data 4</td>
      <td>data 5</td>
    </tr>
    <table>
</div>

This is the best and reliable way to do this. Here is a simple example and after that you can develop your custom logic:

//In .ts
public showUploadButton:boolean = false;

if(some logic)
{
    //your logic
    showUploadButton = true;
}

//In template
<button [class]="showUploadButton ? 'btn btn-default': 'btn btn-info'">Upload</button>

EDIT: yes I agree this is not a correct MVVM approach and I am now using something similar to what is suggested by blindmeis.

One of the way you could to this is

In your Main View Model (where you open the modal):

void OpenModal()
{
    ModalWindowViewModel mwvm = new ModalWindowViewModel();
    Window mw = new Window();
    mw.content = mwvm;
    mw.ShowDialog()
    if(mw.DialogResult == true)
    { 
        // Your Code, you can access property in mwvm if you need.
    }
}

And in your Modal Window View/ViewModel:

XAML:

<Button Name="okButton" Command="{Binding OkCommand}" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}">OK</Button>
<Button Margin="2" VerticalAlignment="Center" Name="cancelButton" IsCancel="True">Cancel</Button>

ViewModel:

public ICommand OkCommand
{
    get
    {
        if (_okCommand == null)
        {
            _okCommand = new ActionCommand<Window>(DoOk, CanDoOk);
        }
        return _okCommand ;
    }
}

void DoOk(Window win)
{
    <!--Your Code-->
    win.DialogResult = true;
    win.Close();
}

bool CanDoOk(Window win) { return true; }

or similar to what is posted here WPF MVVM: How to close a window

You can do that with datetime.strptime()

Example:

>>> from datetime import datetime
>>> datetime.strptime('2012-02-10' , '%Y-%m-%d')
datetime.datetime(2012, 2, 10, 0, 0)
>>> _.isoweekday()
5

You can find the table with all the strptime directive here.

To increment by 2 days if .isweekday() == 6, you can use timedelta():

>>> import datetime
>>> date = datetime.datetime.strptime('2012-02-11' , '%Y-%m-%d')
>>> if date.isoweekday() == 6:
...     date += datetime.timedelta(days=2)
... 
>>> date
datetime.datetime(2012, 2, 13, 0, 0)
>>> date.strftime('%Y-%m-%d')   # if you want a string again
'2012-02-13'

Check the Java API for List.
The get(int index) method is declared to throw only the IndexOutOfBoundException which extends RuntimeException.
You are trying to tell Mockito to throw an exception SomeException() that is not valid to be thrown by that particular method call.

To clarify further.
The List interface does not provide for a checked Exception to be thrown from the get(int index) method and that is why Mockito is failing.
When you create the mocked List, Mockito will use the definition of List.class to creates its mock.

The behavior you are specifying with the when(list.get(0)).thenThrow(new SomeException()) doesn't match the method signature in List API, because get(int index) method does not throw SomeException() so Mockito fails.

If you really want to do this, then have Mockito throw a new RuntimeException() or even better throw a new ArrayIndexOutOfBoundsException() since the API specifies that that is the only valid Exception to be thrown.

There's another way if you don't want to have older Java versions installed you can do the following:

1) Download the iReport-5.6.0.zip from https://sourceforge.net/projects/ireport/files/iReport/iReport-5.6.0/

2) Download jre-7u67-windows-x64.tar.gz (the one packed in a tar) from https://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html

3) Extract the iReport and in the extracted folder that contains the bin and etc folders throw in the jre. For example if you unpack twice the jre-7u67-windows-x64.tar.gz you end up with a folder named jre1.7.0_67. Put that folder in the iReport-5.6.0 directory:

and then go into the etc folder and edit the file ireport.conf and add the following line into it:

For Windows jdkhome=".\jre1.7.0_67"

For Linux jdkhome="./jre1.7.0_67"

Note : jre version may change! according to your download of 1.7

now if you run the ireport_w.exe from the bin folder in the iReport directory it should load just fine.

One way to format it is:

printf("%lld.%.9ld", (long long)ts.tv_sec, ts.tv_nsec);

DisplayFor is also useful for templating. You could write a template for your Model, and do something like this:

@Html.DisplayFor(m => m)

Similar to @Html.EditorFor(m => m). It's useful for the DRY principal so that you don't have to write the same display logic over and over for the same Model.

Take a look at this blog on MVC2 templates. It's still very applicable to MVC3:

http://www.dalsoft.co.uk/blog/index.php/2010/04/26/mvc-2-templates/

It's also useful if your Model has a Data annotation. For instance, if the property on the model is decorated with the EmailAddress data annotation, DisplayFor will render it as a mailto: link.

The error also happens when trying to use the

with multiprocessing.Pool() as pool:
   # ...

with a Python version that is too old (like Python 2.X) and does not support using with together with multiprocessing pools.

(See this answer https://stackoverflow.com/a/25968716/1426569 to another question for more details)

I discovered that this behaviour only occurs after running a particular script, similar to the one in the question. I have no idea why it occurs.

It works (refreshes the graphs) if I put

plt.clf()
plt.cla()
plt.close()

after every plt.show()

Here's a solution using the new async/await syntax.

async function testWait() {
    alert('going to wait for 5 second');
    await wait(5000);
    alert('finally wait is over');
}

function wait(time) {
    return new Promise(resolve => {
        setTimeout(() => {
            resolve();
        }, time);
    });
}

Note: You can call function wait only in async functions

I developed a library for this usecase: https://github.com/sunnykgupta/jsLogger

Features:

1. It safely overrides the console.log.
2. Takes care if the console is not available (oh yes, you need to factor that too.)
3. Stores all logs (even if they are suppressed) for later retrieval.
4. Handles major console functions like log, warn, error, info.

merged = map(names(first), ~c(first[[.x]], second[[.x]])
merged = set_names(merged, names(first))

Using purrr. Also solves the problem of your lists not being in order.

A simple DFS does the work of checking if the given undirected graph has a cycle or not.

Here's the C++ code to the same.

The idea used in the above code is:

If a node which is already discovered/visited is found again and is not the parent node , then we have a cycle.

This can also be explained as below(mentioned by @Rafal Dowgird

If an unexplored edge leads to a node visited before, then the graph contains a cycle.

Netscantools Pro Ping can do ICMP, UDP, and TCP.

To export db rather it is SQLITE or ROOM:

Firstly, add this permission in AndroidManifest.xml file:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Secondly, we drive to code the db functions:

private void exportDB() {
    try {
        File dbFile = new File(this.getDatabasePath(DATABASE_NAME).getAbsolutePath());
        FileInputStream fis = new FileInputStream(dbFile);

        String outFileName = DirectoryName + File.separator +
                DATABASE_NAME + ".db";

        // Open the empty db as the output stream
        OutputStream output = new FileOutputStream(outFileName);

        // Transfer bytes from the inputfile to the outputfile
        byte[] buffer = new byte[1024];
        int length;
        while ((length = fis.read(buffer)) > 0) {
            output.write(buffer, 0, length);
        }
        // Close the streams
        output.flush();
        output.close();
        fis.close();


    } catch (IOException e) {
        Log.e("dbBackup:", e.getMessage());
    }
}

Create Folder on Daily basis with name of folder is Current date:

public void createBackup() {

    sharedPref = getSharedPreferences("dbBackUp", MODE_PRIVATE);
    editor = sharedPref.edit();

    String dt = sharedPref.getString("dt", new SimpleDateFormat("dd-MM-yy").format(new Date()));

    if (dt != new SimpleDateFormat("dd-MM-yy").format(new Date())) {
        editor.putString("dt", new SimpleDateFormat("dd-MM-yy").format(new Date()));

        editor.commit();
    }

    File folder = new File(Environment.getExternalStorageDirectory() + File.separator + "BackupDBs");
    boolean success = true;
    if (!folder.exists()) {
        success = folder.mkdirs();
    }
    if (success) {

        DirectoryName = folder.getPath() + File.separator + sharedPref.getString("dt", "");
        folder = new File(DirectoryName);
        if (!folder.exists()) {
            success = folder.mkdirs();
        }
        if (success) {
            exportDB();
        }
    } else {
        Toast.makeText(this, "Not create folder", Toast.LENGTH_SHORT).show();
    }

}

Assign the DATABASE_NAME without .db extension and its data type is string

To add an image to left, right, top or bottom, you can use attributes like this:

android:drawableLeft
android:drawableRight
android:drawableTop
android:drawableBottom

The sample code is given above. You can also achieve this using relative layout.

It's not impossible without CSS. For example as a list item:

<li style="border-bottom: 1px dashed"><!--content --></li>

Another option that nobody here has mentioned yet is to do a staggered load of the database using a tool like BigDump to work around the limit. It's a simple PHP script that loads a chunk of the database at a time before restarting itself and moving on the the next chunk.

Putting on my gravedigger hat...

The best way I've found to address this is at compile time. Since you're the one setting prefix anyway might as well tell the executable explicitly where to find its shared libraries. Unlike OpenSSL and other software packages, Python doesn't give you nice configure directives to handle alternate library paths (not everyone is root you know...) In the simplest case all you need is the following:

./configure --enable-shared \
            --prefix=/usr/local \
            LDFLAGS="-Wl,--rpath=/usr/local/lib"

Or if you prefer the non-linux version:

./configure --enable-shared \
            --prefix=/usr/local \
            LDFLAGS="-R/usr/local/lib"

The "rpath" flag tells python it has runtime libraries it needs in that particular path. You can take this idea further to handle dependencies installed to a different location than the standard system locations. For example, on my systems since I don't have root access and need to make almost completely self-contained Python installs, my configure line looks like this:

./configure --enable-shared \
            --with-system-ffi \
            --with-system-expat \
            --enable-unicode=ucs4 \
            --prefix=/apps/python-${PYTHON_VERSION} \
            LDFLAGS="-L/apps/python-${PYTHON_VERSION}/extlib/lib -Wl,--rpath=/apps/python-${PYTHON_VERSION}/lib -Wl,--rpath=/apps/python-${PYTHON_VERSION}/extlib/lib" \
            CPPFLAGS="-I/apps/python-${PYTHON_VERSION}/extlib/include"

In this case I am compiling the libraries that python uses (like ffi, readline, etc) into an extlib directory within the python directory tree itself. This way I can tar the python-${PYTHON_VERSION} directory and land it anywhere and it will "work" (provided you don't run into libc or libm conflicts). This also helps when trying to run multiple versions of Python on the same box, as you don't need to keep changing your LD_LIBRARY_PATH or worry about picking up the wrong version of the Python library.

Edit: Forgot to mention, the compile will complain if you don't set the PYTHONPATH environment variable to what you use as your prefix and fail to compile some modules, e.g., to extend the above example, set the PYTHONPATH to the prefix used in the above example with export PYTHONPATH=/apps/python-${PYTHON_VERSION}...

You could make it into a module and expose your inner function by returning it in an Object.

function outer() { 
    function inner() {
        console.log("hi");
    }
    return {
        inner: inner
    };
}
var foo = outer();
foo.inner();

Make sure your packaging strategy defined in your pom.xml is not "pom". It should be "jar" or anything else. Once you do that, update your project right clicking on it and go to Maven -> Update Project...

org.json.simple.JSONObject.escape() escapes quotes,\, /, \r, \n, \b, \f, \t and other control characters. It can be used to escape JavaScript codes.

import org.json.simple.JSONObject;
String test =  JSONObject.escape("your string");

I used the following:

import matplotlib.pyplot as plt

p1 = plt.plot(dates, temp, 'r-', label="Temperature (celsius)")  
p2 = plt.plot(dates, psal, 'b-', label="Salinity (psu)")  
plt.legend(loc='upper center', numpoints=1, bbox_to_anchor=(0.5, -0.05),        ncol=2, fancybox=True, shadow=True)

plt.savefig('data.png')  
plt.show()  
f.close()
plt.close()

I found very important to use plt.show after saving the figure, otherwise it won't work.figure exported in png

Here's a super-simple example with basic authentication, headers, and exception handling...

private HttpHeaders createHttpHeaders(String user, String password)
{
    String notEncoded = user + ":" + password;
    String encodedAuth = "Basic " + Base64.getEncoder().encodeToString(notEncoded.getBytes());
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    headers.add("Authorization", encodedAuth);
    return headers;
}

private void doYourThing() 
{
    String theUrl = "http://blah.blah.com:8080/rest/api/blah";
    RestTemplate restTemplate = new RestTemplate();
    try {
        HttpHeaders headers = createHttpHeaders("fred","1234");
        HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
        ResponseEntity<String> response = restTemplate.exchange(theUrl, HttpMethod.GET, entity, String.class);
        System.out.println("Result - status ("+ response.getStatusCode() + ") has body: " + response.hasBody());
    }
    catch (Exception eek) {
        System.out.println("** Exception: "+ eek.getMessage());
    }
}

Since you ask for other better ways to handle the problem, here's another way using data.table:

require(data.table) ## 1.9.2+
setDT(df)
df[a %in% c(0,1,3,4) | c == 4, g := 3L]
df[a %in% c(2,5,7) | (a==1 & b==4), g := 2L]

Note the order of conditional statements is reversed to get g correctly. There's no copy of g made, even during the second assignment - it's replaced in-place.

On larger data this would have better performance than using nested if-else, as it can evaluate both 'yes' and 'no' cases, and nesting can get harder to read/maintain IMHO.

Here's a benchmark on relatively bigger data:

# R version 3.1.0
require(data.table) ## 1.9.2
require(dplyr)
DT <- setDT(lapply(1:6, function(x) sample(7, 1e7, TRUE)))
setnames(DT, letters[1:6])
# > dim(DT) 
# [1] 10000000        6
DF <- as.data.frame(DT)

DT_fun <- function(DT) {
    DT[(a %in% c(0,1,3,4) | c == 4), g := 3L]
    DT[a %in% c(2,5,7) | (a==1 & b==4), g := 2L]
}

DPLYR_fun <- function(DF) {
    mutate(DF, g = ifelse(a %in% c(2,5,7) | (a==1 & b==4), 2L, 
            ifelse(a %in% c(0,1,3,4) | c==4, 3L, NA_integer_)))
}

BASE_fun <- function(DF) { # R v3.1.0
    transform(DF, g = ifelse(a %in% c(2,5,7) | (a==1 & b==4), 2L, 
            ifelse(a %in% c(0,1,3,4) | c==4, 3L, NA_integer_)))
}

system.time(ans1 <- DT_fun(DT))
#   user  system elapsed 
#  2.659   0.420   3.107 

system.time(ans2 <- DPLYR_fun(DF))
#   user  system elapsed 
# 11.822   1.075  12.976 

system.time(ans3 <- BASE_fun(DF))
#   user  system elapsed 
# 11.676   1.530  13.319 

identical(as.data.frame(ans1), as.data.frame(ans2))
# [1] TRUE

identical(as.data.frame(ans1), as.data.frame(ans3))
# [1] TRUE

Not sure if this is an alternative you'd asked for, but I hope it helps.

As you noted yourself, fmin and fmax were introduced in C99. Standard C++ library doesn't have fmin and fmax functions. Until C99 standard library gets incorporated into C++ (if ever), the application areas of these functions are cleanly separated. There's no situation where you might have to "prefer" one over the other.

You just use templated std::min/std::max in C++, and use whatever is available in C.

Here's some more detailed information on what Client, Resource, and Session are all about.

Client:

• low-level AWS service access
• generated from AWS service description
• exposes botocore client to the developer
• typically maps 1:1 with the AWS service API
• all AWS service operations are supported by clients
• snake-cased method names (e.g. ListBuckets API => list_buckets method)

Here's an example of client-level access to an S3 bucket's objects (at most 1000**):

import boto3

client = boto3.client('s3')
response = client.list_objects_v2(Bucket='mybucket')
for content in response['Contents']:
    obj_dict = client.get_object(Bucket='mybucket', Key=content['Key'])
    print(content['Key'], obj_dict['LastModified'])

** you would have to use a paginator, or implement your own loop, calling list_objects() repeatedly with a continuation marker if there were more than 1000.

Resource:

• higher-level, object-oriented API
• generated from resource description
• uses identifiers and attributes
• has actions (operations on resources)
• exposes subresources and collections of AWS resources
• does not provide 100% API coverage of AWS services

Here's the equivalent example using resource-level access to an S3 bucket's objects (all):

import boto3

s3 = boto3.resource('s3')
bucket = s3.Bucket('mybucket')
for obj in bucket.objects.all():
    print(obj.key, obj.last_modified)

Note that in this case you do not have to make a second API call to get the objects; they're available to you as a collection on the bucket. These collections of subresources are lazily-loaded.

You can see that the Resource version of the code is much simpler, more compact, and has more capability (it does pagination for you). The Client version of the code would actually be more complicated than shown above if you wanted to include pagination.

Session:

• stores configuration information (primarily credentials and selected region)
• allows you to create service clients and resources
• boto3 creates a default session for you when needed

A useful resource to learn more about these boto3 concepts is the introductory re:Invent video.

You can cast datetime to time

select CAST(GETDATE() as time)

If you want a hh:mm format

select cast(CAST(GETDATE() as time) as varchar(5))

The current state of a socket is determined by 'keep-alive' activity. In your case, this is possible that when you are issuing the send call, the keep-alive activity tells that the socket is active and so the send call will write the required data (40 bytes) in to the buffer and returns without giving any error.

When you are sending a bigger chunk, the send call goes in to blocking state.

The send man page also confirms this:

When the message does not fit into the send buffer of the socket, send() normally blocks, unless the socket has been placed in non-blocking I/O mode. In non-blocking mode it would return EAGAIN in this case

So, while blocking for the free available buffer, if the caller is notified (by keep-alive mechanism) that the other end is no more present, the send call will fail.

Predicting the exact scenario is difficult with the mentioned info, but I believe, this should be the reason for you problem.

I used the solution below to export all datagrid values to a text file, rather than using the column names you can use the column index instead.

foreach (DataGridViewRow row in xxxCsvDG.Rows)
{
    File.AppendAllText(csvLocation, row.Cells[0].Value + "," + row.Cells[1].Value + "," + row.Cells[2].Value + "," + row.Cells[3].Value + Environment.NewLine);
}

I know it's late but I use this command for Oracle:

select column_name,data_type,data_length from all_tab_columns where TABLE_NAME = 'xxxx' AND OWNER ='xxxxxxxxxx'

I work on a Windows machine. And here are some pointers for successful installation of lxml (with python 2.6 and later).

Have the following installed:

1. MingGW.
2. libxml2 version 2.7.0 or later.
3. libxslt version 1.1.23 or later.

All are not available at a pip install.

libxml2's windows binary is found here.

libxslt is found here.

After you are done with the above two,

do : pip install lxml.

Another workaround is using the stable releases from PyPI or the unofficial Windows binaries by Christoph Gohlke (found here).

But while mocking read-only properties means properties with getter method only you should declare it as virtual otherwise System.NotSupportedException will be thrown because it is only supported in VB as moq internally override and create proxy when we mock anything.

realpath <path to the symlink file> should do the trick.

This same Facebook error happened to me in the Production environment. The reason was I had 2 apps registered with Facebook (Local, Production) but I hardcoded the Local app ID into the source code and forgot to switch it out for the Production app ID before deployment.

Best practice dictates you shouldn't have the app ID hardcoded into the source code but if you do, do not mismatch your various Facebook app IDs like I mistakenly did.

Besides the already stated answers about using Vector, Vector also has a bunch of methods around enumeration and element retrieval which are different than the List interface, and developers (especially those who learned Java before 1.2) can tend to use them if they are in the code. Although Enumerations are faster, they don't check if the collection was modified during iteration, which can cause issues, and given that Vector might be chosen for its syncronization - with the attendant access from multiple threads, this makes it a particularly pernicious problem. Usage of these methods also couples a lot of code to Vector, such that it won't be easy to replace it with a different List implementation.

Correct answer is simply:

SELECT a.group_id
FROM a 
LEFT JOIN b ON a.group_id=b.group_id  and b.user_id = 4
where b.user_id is null
  and a.keyword like '%keyword%'

Here we are checking user_id = 4 (your user id from the session). Since we have it in the join criteria, it will return null values for any row in table b that does not match the criteria - ie, any group that that user_id is NOT in.

From there, all we need to do is filter for the null values, and we have all the groups that your user is not in.

As stated in the other responses, the response body needs special treatment so it can be read repeatedly (by default, its contents get consumed on the first read).

Instead of using the BufferingClientHttpRequestFactory when setting up the request, the interceptor itself can wrap the response and make sure the content is retained and can be repeatedly read (by the logger as well as by the consumer of the response):

My interceptor, which

• buffers the response body using a wrapper
• logs in a more compact way
• logs the status code identifier as well (e.g. 201 Created)
• includes a request sequence number allowing to easily distinguish concurrent log entries from multiple threads

Code:

public class LoggingInterceptor implements ClientHttpRequestInterceptor {

    private final Logger log = LoggerFactory.getLogger(getClass());
    private AtomicInteger requestNumberSequence = new AtomicInteger(0);

    @Override
    public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {
        int requestNumber = requestNumberSequence.incrementAndGet();
        logRequest(requestNumber, request, body);
        ClientHttpResponse response = execution.execute(request, body);
        response = new BufferedClientHttpResponse(response);
        logResponse(requestNumber, response);
        return response;
    }

    private void logRequest(int requestNumber, HttpRequest request, byte[] body) {
        if (log.isDebugEnabled()) {
            String prefix = requestNumber + " > ";
            log.debug("{} Request: {} {}", prefix, request.getMethod(), request.getURI());
            log.debug("{} Headers: {}", prefix, request.getHeaders());
            if (body.length > 0) {
                log.debug("{} Body: \n{}", prefix, new String(body, StandardCharsets.UTF_8));
            }
        }
    }

    private void logResponse(int requestNumber, ClientHttpResponse response) throws IOException {
        if (log.isDebugEnabled()) {
            String prefix = requestNumber + " < ";
            log.debug("{} Response: {} {} {}", prefix, response.getStatusCode(), response.getStatusCode().name(), response.getStatusText());
            log.debug("{} Headers: {}", prefix, response.getHeaders());
            String body = StreamUtils.copyToString(response.getBody(), StandardCharsets.UTF_8);
            if (body.length() > 0) {
                log.debug("{} Body: \n{}", prefix, body);
            }
        }
    }

    /**

    private static class BufferedClientHttpResponse implements ClientHttpResponse {

        private byte[] body;

        }

        @Override
        public HttpStatus getStatusCode() throws IOException {
            return response.getStatusCode();
        }

        @Override
        public int getRawStatusCode() throws IOException {
            return response.getRawStatusCode();
        }

        @Override
        public String getStatusText() throws IOException {
            return response.getStatusText();
        }

        @Override
        public void close() {
            response.close();
        }

        @Override

            if (body == null) {

To convert the private key from PKCS#1 to PKCS#8 with openssl:

# openssl pkcs8 -topk8 -inform PEM -outform PEM -nocrypt -in pkcs1.key -out pkcs8.key

That will work as long as you have the PKCS#1 key in PEM (text format) as described in the question.

The top post has 'as TextView' appended on the end. You might get other compiler errors if you leave this on. The following should be fine.

Where 'android_text' is the ID of your textView

You don't need to change the compliance level here, or rather, you should but that's not the issue.

The code compliance ensures your code is compatible with a given Java version.

For instance, if you have a code compliance targeting Java 6, you can't use Java 7's or 8's new syntax features (e.g. the diamond, the lambdas, etc. etc.).

The actual issue here is that you are trying to compile something in a Java version that seems different from the project dependencies in the classpath.

Instead, you should check the JDK/JRE you're using to build.

In Eclipse, open the project properties and check the selected JRE in the Java build path.

If you're using custom Ant (etc.) scripts, you also want to take a look there, in case the above is not sufficient per se.

This is an error that you see when your emulator has the "Use host GPU" setting checked. If you uncheck it then the error goes away. Of course, then your emulator is not as responsive anymore.

Try using

Worksheet.Protect "Password", UserInterfaceOnly := True

If the UserInterfaceOnly parameter is set to true, VBA code can modify protected cells.

Simply

if(isset($_POST['filename'])){
 $filename = $_POST['filename'];
 echo $filename;
}
else{
 echo "POST filename is not assigned";
}

You are looking for the the MySQL functions FROM_UNIXTIME() and UNIX_TIMESTAMP().

Use them in your SQL, e.g.:

mysql> SELECT UNIX_TIMESTAMP(NOW());
+-----------------------+
| UNIX_TIMESTAMP(NOW()) |
+-----------------------+
|            1311343579 |
+-----------------------+
1 row in set (0.00 sec)

mysql> SELECT FROM_UNIXTIME(1311343579);
+---------------------------+
| FROM_UNIXTIME(1311343579) |
+---------------------------+
| 2011-07-22 15:06:19       |
+---------------------------+
1 row in set (0.00 sec)

This work at least in the Debian Jessie image hosted by Google:

The way to enable to switch from you regular to the root user (AKA “super user”) after authentificating with your Google Computer Engine (GCE) User in the local environment (your Linux server in GCE) is pretty straight forward, in fact it just involves just one command to enable it and another every time to use it:

$ sudo passwd
Enter the new UNIX password: <your new root password>
Retype the new UNIX password: <your new root password>
passwd: password updated successfully

After executing the previous command and once logged with your GCE User you will be able to switch to root anytime by just entering the following command:

$ su
Password: <your newly created root password>
root@intance:/#

As we say in economics “caveat emptor” or buyer be aware: Using the root user is far from a best practice in system’s administration. Using it can be the cause a lot of trouble, from wiping everything in your drives and boot disks without a hiccup to many other nasty stuff that would be laborious to backtrack, troubleshoot and rebuilt. On the other hand, I have never met a SysAdmin that doesn’t think he knows better and root more than he should.

REMEMBER: We humans are programmed in such a way that given enough time at one at some point or another are going to press enter without taking into account that we have escalated to root and I can assure you that it will great source of pain, regret and extra work. PLEASE USE ROOT PRIVILEGES SPARSELY AND WITH EXTREME CARE.

Having said all the boring stuff, Have fun, live on the edge, life is short, you only get to live it once, the more you break the more you learn.

I'm not using YUI, but in case it helps anyone else - my issue was that I had duplicate ID's on the page (was working inside a dialog and forgot about the page underneath).

Changing the ID so it was unique allowed me to use the methods listed in Sangeet's answer.

Had a similar issue. But it is important to understand the root cause and it may vary for different use cases.

Scenario 1
You are trying to decrypt a value which was not encoded correctly in the first place.

byte[] encryptedBytes = Base64.decodeBase64(encryptedBase64String);

If the String is misconfigured for certain reason or has not been encoded correctly, you would see the error " Input length must be multiple of 16 when decrypting with padded cipher"

Scenario 2
Now if by any chance you are using this encoded string in url (trying to pass in the base64Encoded value in url, it will fail. You should do URLEncoding and then pass in the token, it will work.

Scenario 3
When integrating with one of the vendors, we found that we had to do encryption of Base64 using URLEncoder but then we need not decode it because it was done internally by the Vendor

See In eclipse, ctrl-click goes to the declaration of the method I clicked. For interfaces with one implementation, how can I just directly to that implementation? for some alternative solutions.

• Anyway, I think you might be looking for something like this:

http://eclipse-tools.sourceforge.net/implementors/

This solution is for Vue-2 users:

1. In vue-2 if you don't like to keep your files in static folder (relevant info), or
2. In vue-2 & vue-cli-3 if you don't like to keep your files in public folder (static folder is renamed to public):

The simple solution is :)

<img src="@/assets/img/clear.gif" /> // just do this:
<img :src="require(`@/assets/img/clear.gif`)" // or do this:
<img :src="require(`@/assets/img/${imgURL}`)" // if pulling from: data() {return {imgURL: 'clear.gif'}}

If you like to keep your static images in static/assets/img or public/assets/img folder, then just do:

<img src="./assets/img/clear.gif" />
<img src="/assets/img/clear.gif" /> // in some case without dot ./

sadly, n doesn't worked for me. I use node version manager or nvm and it works like a charm. heres the link on how to install nvm: https://github.com/creationix/nvm#installation

• nvm i 8.11.2 upgrade to latest LTS
• nvm use 8.11.2 use it
• node -v check your latest version

By declaring it global inside the function that accesses it:

g_c = 0

class TestClass():
    def run(self):
        global g_c
        for i in range(10):
            g_c = 1
            print(g_c)

The Python documentation says this, about the global statement:

The global statement is a declaration which holds for the entire current code block.

• Edit ---> Project Settings ---> Time ... decrease "Fixed Timestep" value .. This will solve the problem but it can affect performance negatively.

• Another solution is could be calculate the coordinates (for example, you have a ball and wall. Ball will hit to wall. So calculate coordinates of wall and set hitting process according these cordinates )

Following STEPS worked for me with hadoop 2.2.0,

STEP 1 stop hadoop

hduser@prayagupd$ /usr/local/hadoop-2.2.0/sbin/stop-dfs.sh

STEP 2 remove tmp folder

hduser@prayagupd$ sudo rm -rf /app/hadoop/tmp/

STEP 3 create /app/hadoop/tmp/

hduser@prayagupd$ sudo mkdir -p /app/hadoop/tmp
hduser@prayagupd$ sudo chown hduser:hadoop /app/hadoop/tmp
hduser@prayagupd$ sudo chmod 750 /app/hadoop/tmp

STEP 4 format namenode

hduser@prayagupd$ hdfs namenode -format

STEP 5 start dfs

hduser@prayagupd$ /usr/local/hadoop-2.2.0/sbin/start-dfs.sh

STEP 6 check jps

hduser@prayagupd$ $ jps
11342 Jps
10804 DataNode
11110 SecondaryNameNode
10558 NameNode

This happens when you have 1 name for the Java class on hard disk and another name of Java class in the code!!

For example, I renamed my MainActivity class to MainnActivity only (!) in the code. I got this error immediately.

There is also a visual indicator in the Project tab of Android Studio - a class inside a class, like you have nested classed, but with an error indicator.

The solution is to simply rename class name in the Project tab (SHIFT + F6) to match the name in the Java code.

I know your question does not specify if you are trying to open all a tags in a new window or only the external links.

But in case you only want external links to open in a new tab you can do this:

$( 'a[href^="http://"]' ).attr( 'target','_blank' )
$( 'a[href^="https://"]' ).attr( 'target','_blank' )

If you want to pass variables to the server using GET that would be the way yes. Remember to escape (urlencode) them properly!

It is also possible to use POST, if you dont want your variables to be visible.

A complete sample would be:

var url = "bla.php";
var params = "somevariable=somevalue&anothervariable=anothervalue";
var http = new XMLHttpRequest();

http.open("GET", url+"?"+params, true);
http.onreadystatechange = function()
{
    if(http.readyState == 4 && http.status == 200) {
        alert(http.responseText);
    }
}
http.send(null);

To test this, (using PHP) you could var_dump $_GET to see what you retrieve.

You can do this in jEdit, by using the "Return value of a BeanShell snippet" option in jEdit's find and replace dialog. Just search for " [a-z]" and replace it by " _0.toUpperCase()" (without quotes)

phihag's answer puts each row in a single cell, while you are asking for each value to be in a separate cell. This seems to do it:

<?php
// Create a table from a csv file 
echo "<html><body><table>\n\n";
$f = fopen("so-csv.csv", "r");
while (($line = fgetcsv($f)) !== false) {
        $row = $line[0];    // We need to get the actual row (it is the first element in a 1-element array)
        $cells = explode(";",$row);
        echo "<tr>";
        foreach ($cells as $cell) {
            echo "<td>" . htmlspecialchars($cell) . "</td>";
        }
        echo "</tr>\n";
}
fclose($f);
echo "\n</table></body></html>";
?>

I know this is 5 years later, but the replies above don't address what was wrong with your software. (Well, Yuushi's does, but I didn't realise until I had typed this - doh!). They answer the question in the title How can I initialize C++ object member variables in the constructor? This is about the other questions: Am I using the right approach but the wrong syntax? Or should I be coming at this from a different direction?

Programming style is largely a matter of opinion, but an alternative view to doing as much as possible in a constructor is to keep constructors down to a bare minimum, often having a separate initialization function. There is no need to try to cram all initialization into a constructor, never mind trying to force things at times into the constructors initialization list.

So, to the point, what was wrong with your software?

private:
    ThingOne* ThingOne;
    ThingTwo* ThingTwo;

Note that after these lines, ThingOne (and ThingTwo) now have two meanings, depending on context.

Outside of BigMommaClass, ThingOne is the class you created with #include "ThingOne.h"

Inside BigMommaClass, ThingOne is a pointer.

That is assuming the compiler can even make sense of the lines and doesn't get stuck in a loop thinking that ThingOne is a pointer to something which is itself a pointer to something which is a pointer to ...

Later, when you write

this->ThingOne = ThingOne(100);
this->ThingTwo = ThingTwo(numba1, numba2);

bear in mind that inside of BigMommaClass your ThingOne is a pointer.

If you change the declarations of the pointers to include a prefix (p)

private:
    ThingOne* pThingOne;
    ThingTwo* pThingTwo;

Then ThingOne will always refer to the class and pThingOne to the pointer.

It is then possible to rewrite

this->ThingOne = ThingOne(100);
this->ThingTwo = ThingTwo(numba1, numba2);

as

pThingOne = new ThingOne(100);
pThingTwo = new ThingTwo(numba1, numba2);

which corrects two problems: the double meaning problem, and the missing new. (You can leave this-> if you like!)

With that in place, I can add the following lines to a C++ program of mine and it compiles nicely.

class ThingOne{public:ThingOne(int n){};};
class ThingTwo{public:ThingTwo(int x, int y){};};

class BigMommaClass {

    public:
            BigMommaClass(int numba1, int numba2);

    private:
            ThingOne* pThingOne;
            ThingTwo* pThingTwo;
};

BigMommaClass::BigMommaClass(int numba1, int numba2)
{
    pThingOne = new ThingOne(numba1 + numba2);
    pThingTwo = new ThingTwo(numba1, numba2);
};

When you wrote

this->ThingOne = ThingOne(100);
this->ThingTwo = ThingTwo(numba1, numba2);

the use of this-> tells the compiler that the left hand side ThingOne is intended to mean the pointer. However we are inside BigMommaClass at the time and it's not necessary.

The problem is with the right hand side of the equals where ThingOne is intended to mean the class. So another way to rectify your problems would have been to write

this->ThingOne = new ::ThingOne(100);
this->ThingTwo = new ::ThingTwo(numba1, numba2);

or simply

ThingOne = new ::ThingOne(100);
ThingTwo = new ::ThingTwo(numba1, numba2);

using :: to change the compiler's interpretation of the identifier.

There are two parts to your question.

1) How to focus an input on page load?

You can just add the autofocus attribute to the input.

<input id="myinputbox" type="text" autofocus>

However, this might not be supported in all browsers, so we can use javascript.

window.onload = function() {
  var input = document.getElementById("myinputbox").focus();
}

2) How to place cursor at the end of the input text?

Here's a non-jQuery solution with some borrowed code from another SO answer.

function placeCursorAtEnd() {
  if (this.setSelectionRange) {
    // Double the length because Opera is inconsistent about 
    // whether a carriage return is one character or two.
    var len = this.value.length * 2;
    this.setSelectionRange(len, len);
  } else {
    // This might work for browsers without setSelectionRange support.
    this.value = this.value;
  }

  if (this.nodeName === "TEXTAREA") {
    // This will scroll a textarea to the bottom if needed
    this.scrollTop = 999999;
  }
};

window.onload = function() {
  var input = document.getElementById("myinputbox");

  if (obj.addEventListener) {
    obj.addEventListener("focus", placeCursorAtEnd, false);
  } else if (obj.attachEvent) {
    obj.attachEvent('onfocus', placeCursorAtEnd);
  }

  input.focus();
}

Here's an example of how I would accomplish this with jQuery.

<input type="text" autofocus>

<script>
$(function() {
  $("[autofocus]").on("focus", function() {
    if (this.setSelectionRange) {
      var len = this.value.length * 2;
      this.setSelectionRange(len, len);
    } else {
      this.value = this.value;
    }
    this.scrollTop = 999999;
  }).focus();
});
</script>

If the data is not null-terminated, you should use -initWithData:encoding:

NSString* newStr = [[NSString alloc] initWithData:theData encoding:NSUTF8StringEncoding];

If the data is null-terminated, you should instead use -stringWithUTF8String: to avoid the extra \0 at the end.

NSString* newStr = [NSString stringWithUTF8String:[theData bytes]];

(Note that if the input is not properly UTF-8-encoded, you will get nil.)

Swift variant:

let newStr = String(data: data, encoding: .utf8)
// note that `newStr` is a `String?`, not a `String`.

If the data is null-terminated, you could go though the safe way which is remove the that null character, or the unsafe way similar to the Objective-C version above.

// safe way, provided data is \0-terminated
let newStr1 = String(data: data.subdata(in: 0 ..< data.count - 1), encoding: .utf8)
// unsafe way, provided data is \0-terminated
let newStr2 = data.withUnsafeBytes(String.init(utf8String:))

VPNs can sometimes cause this error as well, if they provide some type of auto-blocking. Disabling the VPN worked for my case.

Flexible Box Layout Module - 8.1. Aligning with auto margins

Auto margins on flex items have an effect very similar to auto margins in block flow:

• During calculations of flex bases and flexible lengths, auto margins are treated as 0.

• Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Therefore you could use margin-top: auto to distribute the space between the other elements and the last element.

This will position the last element at the bottom.

p:last-of-type {
  margin-top: auto;
}

.container {
  display: flex;
  flex-direction: column;
  border: 1px solid #000;
  min-height: 200px;
  width: 100px;
}
p {
  height: 30px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-top: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
</div>

Likewise, you can also use margin-left: auto or margin-right: auto for the same alignment horizontally.

p:last-of-type {
  margin-left: auto;
}

.container {
  display: flex;
  width: 100%;
  border: 1px solid #000;
}
p {
  height: 50px;
  width: 50px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-left: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
  <p></p>
</div>

This should work.

<div my-method='theMethodToBeCalled'></div>

app.directive("myMethod",function($parse) {
  restrict:'A',
  scope: {theMethodToBeCalled: "="}
  link:function(scope,element,attrs) {
     $(element).on('theEvent',function( e, rowid ) {
        id = // some function called to determine id based on rowid
        scope.theMethodToBeCalled(id);
     }
  }
}

app.controller("myController",function($scope) {
   $scope.theMethodToBeCalled = function(id) { alert(id); };
}

stockPicker = [[UIPickerView alloc] init];
stockPicker.frame = CGRectMake(70.0,155, 180,100);

If You want to set the size of UiPickerView. Above code is surely gonna work for u.

The best way for me was to put it in a hidden div in php blade

<div hidden id="token">{{$token}}</div>

then call it in javascript as a constant to avoid undefined var errors

const token = document.querySelector('div[id=token]').textContent

Yes, you must open php.ini and remove the semicolon to:

;extension=php_openssl.dll

If you don't have that line, check that you have the file (In my PC is on D:\xampp\php\ext) and add this to php.ini in the "Dynamic Extensions" section:

extension=php_openssl.dll

Things have changed for PHP > 7. This is what i had to do for PHP 7.2.

Step: 1: Uncomment extension=openssl

Step: 2: Uncomment extension_dir = "ext"

Step: 3: Restart xampp.

Done.

Explanation: ( From php.ini )

If you wish to have an extension loaded automatically, use the following syntax:

extension=modulename

Note : The syntax used in previous PHP versions (extension=<ext>.so and extension='php_<ext>.dll) is supported for legacy reasons and may be deprecated in a future PHP major version. So, when it is possible, please move to the new (extension=<ext>) syntax.

Special Note: Be sure to appropriately set the extension_dir directive.

Why does this error occur?

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.

The first element in a collection is generally located at index 0. The last element is at index n-1, where n is the Size of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1, you're going to get an error.

How indexing arrays works

When you declare an array like this:

var array = new int[6]

The first and last elements in the array are

var firstElement = array[0];
var lastElement = array[5];

So when you write:

var element = array[5];

you are retrieving the sixth element in the array, not the fifth one.

Typically, you would loop over an array like this:

for (int index = 0; index < array.Length; index++)
{
    Console.WriteLine(array[index]);
}

This works, because the loop starts at zero, and ends at Length-1 because index is no longer less than Length.

This, however, will throw an exception:

for (int index = 0; index <= array.Length; index++)
{
    Console.WriteLine(array[index]);
}

Notice the <= there? index will now be out of range in the last loop iteration, because the loop thinks that Length is a valid index, but it is not.

How other collections work

Lists work the same way, except that you generally use Count instead of Length. They still start at zero, and end at Count - 1.

for (int index = 0; i < list.Count; index++)
{
    Console.WriteLine(list[index]);
} 

However, you can also iterate through a list using foreach, avoiding the whole problem of indexing entirely:

foreach (var element in list)
{
    Console.WriteLine(element.ToString());
}

You cannot index an element that hasn't been added to a collection yet.

var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]);  // Throws exception.

A previous answer on this page describes how to use .htaccess to force all files of a certain type to download. However, the solution does not work with all file types across all browsers. This is a more reliable way:

<FilesMatch "\.(?i:csv)$">
  ForceType application/octet-stream
  Header set Content-Disposition attachment
</FilesMatch>

You might need to flush your browser cache to see this working correctly.

You can get separate component of a NSDate using NSDateFormatter:

NSDateFormatter *df = [[NSDateFormatter alloc] init];

[df setDateFormat:@"dd"];
myDayString = [df stringFromDate:[NSDate date]];

[df setDateFormat:@"MMM"];
myMonthString = [df stringFromDate:[NSDate date]];

[df setDateFormat:@"yy"];
myYearString = [df stringFromDate:[NSDate date]];

If you wish to get month's number instead of abbreviation, use "MM". If you wish to get integers, use [myDayString intValue];

In PHP arrays are passed to functions by value by default, unless you explicitly pass them by reference, as the following snippet shows:

$foo = array(11, 22, 33);

function hello($fooarg) {
  $fooarg[0] = 99;
}

function world(&$fooarg) {
  $fooarg[0] = 66;
}

hello($foo);
var_dump($foo); // (original array not modified) array passed-by-value

world($foo);
var_dump($foo); // (original array modified) array passed-by-reference

Here is the output:

array(3) {
  [0]=>
  int(11)
  [1]=>
  int(22)
  [2]=>
  int(33)
}
array(3) {
  [0]=>
  int(66)
  [1]=>
  int(22)
  [2]=>
  int(33)
}

The git solution for such scenarios is setting SKIP-WORKTREE BIT. Run only the following command:

git update-index --skip-worktree .classpath .gitignore

It is used when you want git to ignore changes of files that are already managed by git and exist on the index. This is a common use case for config files.

Running git rm --cached doesn't work for the scenario mentioned in the question. If I simplify the question, it says:

How to have .classpath and .project on the repo while each one can change it locally and git ignores this change?

As I commented under the accepted answer, the drawback of git rm --cached is that it causes a change in the index, so you need to commit the change and then push it to the remote repository. As a result, .classpath and .project won't be available on the repo while the PO wants them to be there so anyone that clones the repo for the first time, they can use it.

What is SKIP-WORKTREE BIT?

Based on git documentaion:

Skip-worktree bit can be defined in one (long) sentence: When reading an entry, if it is marked as skip-worktree, then Git pretends its working directory version is up to date and read the index version instead. Although this bit looks similar to assume-unchanged bit, its goal is different from assume-unchanged bit’s. Skip-worktree also takes precedence over assume-unchanged bit when both are set.

More details is available here.

Json.NET has a JsonPropertyAttribute which allows you to specify the name of a JSON property, so your code should be:

public class TeamScore
{
    [JsonProperty("eighty_min_score")]
    public string EightyMinScore { get; set; }
    [JsonProperty("home_or_away")]
    public string HomeOrAway { get; set; }
    [JsonProperty("score ")]
    public string Score { get; set; }
    [JsonProperty("team_id")]
    public string TeamId { get; set; }
}

public class Team
{
    public string v1 { get; set; }
    [JsonProperty("attributes")]
    public TeamScore TeamScores { get; set; }
}

public class RootObject
{
    public List<Team> Team { get; set; }
}

Documentation: Serialization Attributes

The OP states that each plot element overwrites the previous one rather than being combined into a single plot. This can happen even with one of the many suggestions made by other answers. If you select several lines and run them together, say:

plt.plot(<X>, <Y>)
plt.plot(<X>, <Z>)

the plot elements will typically be rendered together, one layer on top of the other. But if you execute the code line-by-line, each plot will overwrite the previous one.

This perhaps is what happened to the OP. It just happened to me: I had set up a new key binding to execute code by a single key press (on spyder), but my key binding was executing only the current line. The solution was to select lines by whole blocks or to run the whole file.

This might be useful for refreshing also. But if you want to keep track of position on the page before you click on a same position.. The following code will help.

Also added a data-confirm for prompting the user if they really want to do that..

Note: I'm using jQuery and js-cookie.js to store cookie info.

$(document).ready(function() {
    // make all links with data-confirm prompt the user first.
    $('[data-confirm]').on("click", function (e) {
        e.preventDefault();
        var msg = $(this).data("confirm");
        if(confirm(msg)==true) {
            var url = this.href;
            if(url.length>0) window.location = url;
            return true;
        }
        return false;
    });

    // on certain links save the scroll postion.
    $('.saveScrollPostion').on("click", function (e) {
        e.preventDefault();
        var currentYOffset = window.pageYOffset;  // save current page postion.
        Cookies.set('jumpToScrollPostion', currentYOffset);
        if(!$(this).attr("data-confirm")) {  // if there is no data-confirm on this link then trigger the click. else we have issues.
            var url = this.href;
            window.location = url;
            //$(this).trigger('click');  // continue with click event.
        }
    });

    // check if we should jump to postion.
    if(Cookies.get('jumpToScrollPostion') !== "undefined") {
        var jumpTo = Cookies.get('jumpToScrollPostion');
        window.scrollTo(0, jumpTo);
        Cookies.remove('jumpToScrollPostion');  // and delete cookie so we don't jump again.
    }
});

A example of using it like this.

<a href='gotopage.html' class='saveScrollPostion' data-confirm='Are you sure?'>Goto what the heck</a>

For me my Script tag was outside the body element. Copied it just before closing the body tag. This worked

enter code here

<h1 id = 'title'>Black Jack</h1>
<h4> by Meg</h4>

<p id="text-area">Welcome to blackJack!</p>
<button id="new-button">New Game</button>
<button id="hitbtn">Hit!</button>
<button id="staybtn">Stay</button>

 <script src="script.js"></script>

When using SQLFiddle, make sure that the separator is set to GO. Also the schema build script is executed in a different connection from the run script, so a temp table created in the one is not visible in the other. This fiddle shows that your code is valid and working in SQL 2012:

SQL Fiddle

MS SQL Server 2012 Schema Setup:

Query 1:

CREATE TABLE #Names
  ( 
    Name1 VARCHAR(100),
    Name2 VARCHAR(100)
  ) 

INSERT INTO #Names
  (Name1, Name2)
VALUES
  ('Matt', 'Matthew'),
  ('Matt', 'Marshal'),
  ('Matt', 'Mattison')

SELECT * FROM #NAMES

Results:

| NAME1 |    NAME2 |
--------------------
|  Matt |  Matthew |
|  Matt |  Marshal |
|  Matt | Mattison |

Here a SSMS 2012 screenshot:

The default specifier depends upon context.

For classes, and interface declarations, the default is package private. This falls between protected and private, allowing only classes in the same package access. (protected is like this, but also allowing access to subclasses outside of the package.)

class MyClass   // package private
{
   int field;    // package private field

   void calc() {  // package private method

   }
}

For interface members (fields and methods), the default access is public. But note that the interface declaration itself defaults to package private.

interface MyInterface  // package private
{
   int field1;         // static final public

   void method1();     // public abstract
}

If we then have the declaration

public interface MyInterface2 extends MyInterface
{

}

Classes using MyInterface2 can then see field1 and method1 from the super interface, because they are public, even though they cannot see the declaration of MyInterface itself.

Complementing the @DanielLew answer, to get the values of the parameteres you have to do this:

URI example: myapp://path/to/what/i/want?keyOne=valueOne&keyTwo=valueTwo

in your activity:

Intent intent = getIntent();
if (Intent.ACTION_VIEW.equals(intent.getAction())) {
  Uri uri = intent.getData();
  String valueOne = uri.getQueryParameter("keyOne");
  String valueTwo = uri.getQueryParameter("keyTwo");
}

__getitem__ can be used to implement "lazy" dict subclasses. The aim is to avoid instantiating a dictionary at once that either already has an inordinately large number of key-value pairs in existing containers, or has an expensive hashing process between existing containers of key-value pairs, or if the dictionary represents a single group of resources that are distributed over the internet.

As a simple example, suppose you have two lists, keys and values, whereby {k:v for k,v in zip(keys, values)} is the dictionary that you need, which must be made lazy for speed or efficiency purposes:

class LazyDict(dict):
    
    def __init__(self, keys, values):
        self.keys = keys
        self.values = values
        super().__init__()
        
    def __getitem__(self, key):
        if key not in self:
            try:
                i = self.keys.index(key)
                self.__setitem__(self.keys.pop(i), self.values.pop(i))
            except ValueError, IndexError:
                raise KeyError("No such key-value pair!!")
        return super().__getitem__(key)

Usage:

>>> a = [1,2,3,4]
>>> b = [1,2,2,3]
>>> c = LazyDict(a,b)
>>> c[1]
1
>>> c[4]
3
>>> c[2]
2
>>> c[3]
2
>>> d = LazyDict(a,b)
>>> d.items()
dict_items([])

I got the same error, when I was trying to import matplotlib.pyplot

In [1]: import matplotlib.pyplot as plt
...
...
ImportError: No module named PyQt4.QtCore

But in my case the problem was due to a missing linux library libGL.so.1

OS : Cent OS 64 bit

Python version : 3.5.2

$> locate libGL.so.1

If this command returns a value, your problem could be different, so please ignore my answer. If it does not return any value and your environment is same as mine, below steps would fix your problem.

$> yum install mesa-libGL.x86_64

This installs the necessary OpenGL libraries for 64 bit Cent OS.

$> locate libGL.so.1
/usr/lib/libGL.so.1

Now go back to iPython and try to import

In [1]: import matplotlib.pyplot as plt

This time it imported successfully.

As pointed out in the comments, you cannot catch an exception that's not thrown by the code within your try block. Try changing your code to:

try{
    Integer.parseInt(args[i-1]); // this only throws a NumberFormatException
}
catch(NumberFormatException e){
    throw new MojException("Bledne dane");
}

Always check the documentation to see what exceptions are thrown by each method. You may also wish to read up on the subject of checked vs unchecked exceptions before that causes you any confusion in the future.

There is no limit to the input of md5 that I know of. Some implementations require the entire input to be loaded into memory before passing it into the md5 function (i.e., the implementation acts on a block of memory, not on a stream), but this is not a limitation of the algorithm itself. The output is always 128 bits. Note that md5 is not an encryption algorithm, but a cryptographic hash. This means that you can use it to verify the integrity of a chunk of data, but you cannot reverse the hashing. Also note that md5 is considered broken, so you shouldn't use it for anything security-related (it's still fine to verify the integrity of downloaded files and such).

I believe your question is to change only width of view dynamically, whereas above methods will change layout properties completely to new one, so I suggest to getLayoutParams() from view first, then set width on layoutParams, and finally set layoutParams to the view, so following below steps to do the same.

View view = findViewById(R.id.nutrition_bar_filled);
LayoutParams layoutParams = view.getLayoutParams();
layoutParams.width = newWidth;
view.setLayoutParams(layoutParams);

The clue is to work with the dict's items (i.e. key-value pair tuples). Then by using the second element of the item as the max key (as opposed to the dict key) you can easily extract the highest value and its associated key.

 mydict = {'A':4,'B':10,'C':0,'D':87}
>>> max(mydict.items(), key=lambda k: k[1])
('D', 87)
>>> min(mydict.items(), key=lambda k: k[1])
('C', 0)

If you do it programmatically in JS it will be like reinventing the wheel. I recommend using a jQuery plugin called jGrowl

Don't forget that integers can be negative:

^\s*-?[0-9]{1,10}\s*$

Here's the meaning of each part:

• ^: Match must start at beginning of string
• \s: Any whitespace character
  • *: Occurring zero or more times
• -: The hyphen-minus character, used to denote a negative integer
  • ?: May or may not occur
• [0-9]: Any character whose ASCII code (or Unicode code point) is between '0' and '9'
  • {1,10}: Occurring at least one, but not more than ten times
• \s: Any whitespace character
  • *: Occurring zero or more times
• $: Match must end at end of string

This ignores leading and trailing whitespace and would be more complex if you consider commas acceptable or if you need to count the minus sign as one of the ten allowed characters.

UIButton* closeBtn = [[UIButton alloc] initWithFrame:CGRectMake(10, 50, 90, 35)];
//Customise this button as you wish then
closeBtn.layer.cornerRadius = 10;
closeBtn.layer.masksToBounds = YES;//Important

I might be too late to answer this question, but wanted to share my input for the benefit of the community. For this example, let me call your matrix 'ANOVA', and I am assuming you're just trying to remove rows from this matrix with 0's only in the 5th column.

indx = []
for i in range(len(ANOVA)):
    if int(ANOVA[i,4]) == int(0):
        indx.append(i)

ANOVA = [x for x in ANOVA if not x in indx]

Single leading underscores is a convention. there is no difference from the interpreter's point of view if whether names starts with a single underscore or not.

Double leading and trailing underscores are used for built-in methods, such as __init__, __bool__, etc.

Double leading underscores w/o trailing counterparts are a convention too, however, the class methods will be mangled by the interpreter. For variables or basic function names no difference exists.

Use the below code in your rounded_edittext.xml :

<?xml version="1.0" encoding="utf-8" ?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:thickness="0dp"
       android:shape="rectangle">

    <stroke android:width="2dp"
            android:color="#2F6699"/>

    <corners android:radius="3dp" />

    <gradient   android:startColor="#C8C8C8"
                android:endColor="#FFFFFF"
                android:type="linear"
                android:angle="270"/>
</shape>

I had a directory of files that I wanted to check. I created an Excel macro to determine ANSI vs. UTF-8. This worked for me.

        Sub GetTextFileEncoding()
        Dim sFile As String
        Dim sPath As String
        Dim sTextLine As String
        Dim iRow As Integer

        'Set Defaults and Initial Values
        iRow = 1
        sPath = "C:textfiles\"
        sFile = Dir(sPath & "*.txt")

        Do While Len(sFile) > 0
            'Get FileType
            'Debug.Print sFile & " - " & FileEncodeType(sPath & sFile)

            'Show on Excel Worksheet
            Cells(iRow, 1).Value = sFile
            Cells(iRow, 2).Value = FileEncodeType(sPath & sFile)

            'Get next file
            sFile = Dir

            'Increment Row
            iRow = iRow + 1
        Loop
    End Sub

    Function FileEncodeType(sFile As String) As String
        Dim bEF As Boolean
        Dim bBB As Boolean
        Dim bBF As Boolean

        bEF = False
        bBB = False
        bBF = False

        Open sFile For Input As #1
            If Not EOF(1) Then
                'Read first line
                Line Input #1, textline
                'Debug.Print textline
                For i = 1 To 3
                    'Debug.Print Asc(Mid(textline, i, 1)) & " - " & Mid(textline, i, 1)
                    Select Case i
                        Case 1
                            If Asc(Mid(textline, i, 1)) = 239 Then
                                bEF = True
                            End If
                        Case 2
                             If Asc(Mid(textline, i, 1)) = 187 Then
                                bBB = True
                            End If
                        Case 3
                             If Asc(Mid(textline, i, 1)) = 191 Then
                                bBF = True
                            End If
                        Case 4

                    End Select
                Next
            End If
        Close #1

        If bEF And bBB And bBF Then
            FileEncodeType = "UTF-8"
        Else
            FileEncodeType = "ANSI"
        End If
    End Function

Use:

function getvalues(){
var inps = document.getElementsByName('pname[]');
for (var i = 0; i <inps.length; i++) {
var inp=inps[i];
    alert("pname["+i+"].value="+inp.value);
}
}

Here is Demo.

this will do the job easily to get the last part of the required URL

$url="http://domain.com/artist/song/music-videos/song-title/9393903";
$requred_string= substr(strrchr($url, "/"), 1);

this will get you the string after first "/" from the right.

So, similar to other solutions here is mine:

// For example you have this relation defined with "user()" method
public function user()
{
    return $this->belongsTo('User');
}
// Just make another one defined with "user_frontend()" method
public function user_frontend()
{
    return $this->belongsTo('User')->select(array('id', 'username'));
}

// Then use it later like this
$thing = new Thing();
$thing->with('user_frontend');

// This way, you get only id and username, 
// and if you want all fields you can do this

$thing = new Thing();
$thing->with('user');

A simple example of escaping quotes in the shell:

$ echo 'abc'\''abc'
abc'abc
$ echo "abc"\""abc"
abc"abc

It's done by finishing an already-opened one ('), placing the escaped one (\'), and then opening another one (').

Alternatively:

$ echo 'abc'"'"'abc'
abc'abc
$ echo "abc"'"'"abc"
abc"abc

It's done by finishing already opened one ('), placing a quote in another quote ("'"), and then opening another one (').

More examples: Escaping single-quotes within single-quoted strings

I would think , in a large file scenario using a stream would be far more efficient, because memory consumption would be very small.

But your algorithm could alternate between using a stream and loading the entire thing in memory based on the file size. I wouldn't be surprised if one is only better than the other under certain criteria.

To run a url, you need a program to get that url. You can try wget or curl. See manuals for available options.

function isVisible(el, isDeep) {
    var elIsVisible = true;

    if("undefined" === typeof isDeep) {

    }

    elIsVisible = elIsVisible && el.offsetWidth > 0 && el.offsetHeight > 0;

    if(isDeep && elIsVisible) {

        while('BODY' != el.tagName && elIsVisible) {

Do check if you have marked the controller class with @RestController annotation.

I have been looking at several solutions to do that and my choice has been oslo.concurrency

It's powerful and relatively well documented. It's based on fasteners.

Other solutions:

• Portalocker: requires pywin32, which is an exe installation, so not possible via pip
• fasteners: poorly documented
• lockfile: deprecated
• flufl.lock: NFS-safe file locking for POSIX systems.
• simpleflock : Last update 2013-07
• zc.lockfile : Last update 2016-06 (as of 2017-03)
• lock_file : Last update in 2007-10

Okay, so here we have two things that are being mixed. First thing, is when you need to mark something to be used only on test, which I agree with @JB Nizet, using the guava annotation would be good.

A different thing, is to test private methods. Why should you test private methods from the outside? I mean.. You should be able to test the object by their public methods, and at the end that its behavior. At least, that we are doing and trying to teach to junior developers, that always try to test private methods (as a good practice).

When you import lib, you're importing the package. The only file to get evaluated and run in this case is the 0 byte __init__.py in the lib directory.

If you want access to your function, you can do something like this from lib.mod1 import mod1 and then run the mod12 function like so mod1.mod12().

If you want to be able to access mod1 when you import lib, you need to put an import mod1 inside the __init__.py file inside the lib directory.

They can be different on word-addressable machines (e.g., Cray PVP systems).

Most computers today are byte-addressable machines, where each address refers to a byte of memory. There, all data pointers are usually the same size, namely the size of a machine address.

On word-adressable machines, each machine address refers instead to a word larger than a byte. On these, a (char *) or (void *) pointer to a byte of memory has to contain both a word address plus a byte offset within the addresed word.

You could use PHP constant:

$array = explode(PHP_EOL, $text);

additional notes:
1. For me this is the easiest and the safest way because it is cross platform compatible (Windows/Linux etc.)
2. It is better to use PHP CONSTANT whenever you can for faster execution

I simply write it this way

in the AspectType file:

class AspectType {
  //blah blah
}
module.exports = AspectType;

and import it like this:

const AspectType = require('./AspectType');
var aspectType = new AspectType;

I suggest using jQuery. What you are doing right now is easy to achieve without jQuery, but as you will want new features and more functionality, jQuery will save you a lot of time. I would also like to mention that you shouldn't have multiple DOM elements with the same ID in one document. In such case use class attribute.

html:

<table id="dsTable">
  <tr>
     <td> Relationship Type </td>
     <td> Date of Birth </td>
     <td> Gender </td>
  </tr>
  <tr>
     <td> Spouse </td>
     <td> 1980-22-03 </td>
     <td> female </td>
     <td> <input type="button" class="addDep" value="Add"/></td>
     <td> <input type="button" class="deleteDep" value="Delete"/></td>
  </tr>
   <tr>
     <td> Child </td>
     <td> 2008-23-06 </td>
     <td> female </td>
     <td> <input type="button" class="addDep" value="Add"/></td>
     <td> <input type="button" class="deleteDep" value="Delete"/></td>
  </tr>
</table>

javascript:

$('body').on('click', 'input.deleteDep', function() {
   $(this).parents('tr').remove();  
});

Remember that you need to reference jQuery:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.3.min.js"></script>

Here a working jsfiddle example: http://jsfiddle.net/p9dey/1/

Actually your command line arguments are practically like an array already. At least, you can treat the $@ variable much like an array. That said, you can convert it into an actual array like this:

myArray=( "$@" )

If you just want to type some arguments and feed them into the $@ value, use set:

$ set -- apple banana "kiwi fruit"
$ echo "$#"
3
$ echo "$@"

Understanding how to use the argument structure is particularly useful in POSIX sh, which has nothing else like an array.

This was a very handy page as I have a requirement to DELETE records from a mySQL table where the expiry date is < Today.

I am on a shared host and CRON did not like the suggestion AndrewKDay. it also said (and I agree) that exposing the password in this way could be insecure.

I then tried turning Events ON in phpMyAdmin but again being on a shared host this was a no no. Sorry fancyPants.

So I turned to embedding the SQL script in a PHP file. I used the example [here][1]

[1]: https://www.w3schools.com/php/php_mysql_create_table.asp stored it in a sub folder somewhere safe and added an empty index.php for good measure. I was then able to test that this PHP file (and my SQL script) was working from the browser URL line.

All good so far. On to CRON. Following the above example almost worked. I ended up calling PHP before the path for my *.php file. Otherwise CRON didn't know what to do with the file.

my cron is set to run once per day and looks like this, modified for security.

00 * * * * php mywebsiteurl.com/wp-content/themes/ForteChildTheme/php/DeleteExpiredAssessment.php

For the final testing with CRON I initially set it to run each minute and had email alerts turned on. This quickly confirmed that it was running as planned and I changed it back to once per day.

Hope this helps.

$('#attached_docs [value="123"]').find ... .remove();

it should do your need however, you cannot duplicate id! remember it

On []: !=, =, == ... are string comparison operators and -eq, -gt ... are arithmetic binary ones.

I would use:

if [ "$#" != "1" ]; then

Or:

if [ $# -eq 1 ]; then

Update: The site below is no longer running because, as they say on the site:

As of January 1, 2016, no publicly trusted CA is allowed to issue a SHA-1 certificate. In addition, SHA-1 support was removed by most modern browsers and operating systems in early 2017. Any new certificate you get should automatically use a SHA-2 algorithm for its signature.

Legacy clients will continue to accept SHA-1 certificates, and it is possible to have requested a certificate on December 31, 2015 that is valid for 39 months. So, it is possible to see SHA-1 certificates in the wild that expire in early 2019.

Original answer:

You can also use https://shaaaaaaaaaaaaa.com/ - set up to make this particular task easy. The site has a text box - you type in your site domain name, click the Go button and it then tells you whether the site is using SHA1 or SHA2.

Background

First step you need add a row with key: View controller-based status bar appearance and value NO to Info.plist file. After that, add 2 functions in your controller to specific only that controller will effect:

override func viewWillAppear(_ animated: Bool) {
       super.viewWillAppear(animated)
       UIApplication.shared.statusBarStyle = .lightContent
}

override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        UIApplication.shared.statusBarStyle = .default    
}

If you need to print the number you can use printf

System.out.printf("%02d", num);

You can use

String.format("%02d", num);

or

(num < 10 ? "0" : "") + num;

or

(""+(100+num)).substring(1);

var bd = document.getElementsByTagName('body')[0];
var time = new Date().getTime();

bd.onmousemove = goLoad;
function goLoad() {
if(new Date().getTime() - time >= 1200000) {
    time = new Date().getTime();
    window.location.reload(true);
    }else{
        time = new Date().getTime();
    }
}

Each time you move the mouse it will check the last time you moved the mouse. If the time interval is greater than 20' it will reload the page, else it will renew the last-time-you-moved-the-mouse.

Assume we have a function sort(int *arraytobesorted,void (*algorithmchosen)(void)) where it can accept a function pointer as its argument which can be used at some point in sort()'s implementation . Then , here the code that is being addressed by the function pointer algorithmchosen is called as callback function .

And see the advantage is that we can choose any algorithm like:

  1.    algorithmchosen = bubblesort
  2.    algorithmchosen = heapsort
  3.    algorithmchosen = mergesort   ...

Which were, say,have been implemented with the prototype:

  1.   `void bubblesort(void)`
  2.   `void heapsort(void)`
  3.   `void mergesort(void)`   ...

This is a concept used in achieving Polymorphism in Object Oriented Programming

You see the two empty -D entries in the g++ command line? They're causing the problem. You must have values in the -D items e.g. -DWIN32

if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:

SYSTEM ?= generic
ENVIRONMENT ?= generic

in the makefile which gives them default values.

Your output looks to be missing the all important output:

<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers

just to clarify, what actually got sent to g++ was -D -DWindows_NT, i.e. define a preprocessor macro called -DWindows_NT; which is of course not a valid identifier (similarly for -D -I.)

You need to make sure that the value you pass to the directory argument is an absolute path, corrected for the current location of your application.

The best way to do this is to configure UPLOAD_FOLDER as a relative path (no leading slash), then make it absolute by prepending current_app.root_path:

@app.route('/uploads/<path:filename>', methods=['GET', 'POST'])
def download(filename):
    uploads = os.path.join(current_app.root_path, app.config['UPLOAD_FOLDER'])
    return send_from_directory(directory=uploads, filename=filename)

It is important to reiterate that UPLOAD_FOLDER must be relative for this to work, e.g. not start with a /.

A relative path could work but relies too much on the current working directory being set to the place where your Flask code lives. This may not always be the case.

Windows:

• Install "Intel x86 Emulator Accelerator (HAXM)" => SDK-Manager/Extras
• Install "Intel x86 Atom System Images" => SDK-Manager/Android 2.3.3

• Go to the Android SDK root folder and navigate to extras\intel\Hardware_Accelerated_Execution_Manager. Execute file IntelHaxm.exe to install. (in Android Studio you can navigate to: Settings -> Android SDK -> SDK Tools -> Intel x86 Emulator Accelerator (HAXM installer))

• Create AVD with "Intel atom x86" CPU/ABI

• Run emulator and check in console that HAXM running (open a Command Prompt window and execute the command: sc query intelhaxm)

Also don't forget install this one

P.S. during AVD creation add emulation memory: Hardware/New/Device ram size/set up value 512 or more

Linux:

• Install KVM: open GOOGLE, write "kvm installation "
• Create AVD with "Intel atom x86" CPU/ABI
• Run from command line: emulator -avd avd_name -qemu -m 512 -enable-kvm
• Or run from Eclipse: Run/Run Configurations/Tab "Target" - > check Intel x86 AVD and in "Additional Emulator Command Line Options" window add: -qemu -m 512 -enable-kvm (click Run)

P.S. For Fedora, for Ubuntu

OS-X:

• In Android SDK Manager, install Intel x86 Atom System Image
• In Android SDK Manager, install Intel x86 Emulator Accelerator (HAXM)
• In finder, go to the install location of the Intel Emulator Accelerator and install IntelHAXM (open the dmg and run the installation). You can find the location by placing your mouse over the Emulator Accelerator entry in the SDK Manager.
• Create or update an AVD and specify Intel Atom x86 as the CPU.

P.S: Check this tool, very convenient even trial

I would like to give you also the idea to disable an <option> with a given defined value (not innerhtml). I recommend to it with jQuery to get the simplest way. See my sample below.

HTML

Status:  
<div id="option">
   <select class="status">
      <option value="hand" selected>Hand</option>
      <option value="simple">Typed</option>
      <option value="printed">Printed</option>
   </select>
</div>

Javascript

The idea here is how to disable Printed option when current Status is Hand

var status = $('#option').find('.status');//to get current the selected value
var op = status.find('option');//to get the elements for disable attribute
(status.val() == 'hand')? op[2].disabled = true: op[2].disabled = false;

You may see how it works here:

You want conda update --all.

conda search --outdated will show outdated packages, and conda update --all will update them (note that the latter will not update you from Python 2 to Python 3, but the former will show Python as being outdated if you do use Python 2).
