Assuming rand gives equal weighting to all bits, then masks with the upper bound.

int i = rand(5) ^ (rand(5) & 2);

rand(5) can only return: 1b, 10b, 11b, 100b, 101b. You only need to concern yourself with sometimes setting the 2 bit.

The below java solution which will print the different combinations as well. Easy to understand. Idea is

for sum 5

The solution is

    5 - 5(i) times 1 = 0
        if(sum = 0)
           print i times 1
    5 - 4(i) times 1 = 1
    5 - 3 times 1 = 2
        2 -  1(j) times 2 = 0
           if(sum = 0)
              print i times 1 and j times 2
    and so on......

If the remaining sum in each loop is lesser than the denomination ie if remaining sum 1 is lesser than 2, then just break the loop

The complete code below

Please correct me in case of any mistakes

public class CoinCombinbationSimple {
public static void main(String[] args) {
    int sum = 100000;
    printCombination(sum);
}

static void printCombination(int sum) {
    for (int i = sum; i >= 0; i--) {
        int sumCopy1 = sum - i * 1;
        if (sumCopy1 == 0) {
            System.out.println(i + " 1 coins");
        }
        for (int j = sumCopy1 / 2; j >= 0; j--) {
            int sumCopy2 = sumCopy1;
            if (sumCopy2 < 2) {
                break;
            }
            sumCopy2 = sumCopy1 - 2 * j;
            if (sumCopy2 == 0) {
                System.out.println(i + " 1 coins " + j + " 2 coins ");
            }
            for (int k = sumCopy2 / 5; k >= 0; k--) {
                int sumCopy3 = sumCopy2;
                if (sumCopy2 < 5) {
                    break;
                }
                sumCopy3 = sumCopy2 - 5 * k;
                if (sumCopy3 == 0) {
                    System.out.println(i + " 1 coins " + j + " 2 coins "
                            + k + " 5 coins");
                }
            }
        }
    }
}

select max(column_name) from table_name
where column_name not in (select max(column_name) from table_name);

not in is a condition that exclude the highest value of column_name.

Reference : programmer interview

I suggest making a tree of letters based on words. The tree would be composed of a letter structs, like this:

letter: char
isWord: boolean

Then you build up the tree, with each depth adding a new letter. In other words, on the first level there'd be the alphabet; then from each of those trees, there'd be another another 26 entries, and so on, until you've spelled out all the words. Hang onto this parsed tree, and it'll make all possible answers faster to look up.

With this parsed tree, you can very quickly find solutions. Here's the pseudo-code:

BEGIN: 
    For each letter:
        if the struct representing it on the current depth has isWord == true, enter it as an answer.
        Cycle through all its neighbors; if there is a child of the current node corresponding to the letter, recursively call BEGIN on it.

This could be sped up with a bit of dynamic programming. For example, in your sample, the two 'A's are both next to an 'E' and a 'W', which (from the point they hit them on) would be identical. I don't have enough time to really spell out the code for this, but I think you can gather the idea.

Also, I'm sure you'll find other solutions if you Google for "Boggle solver".

The SET command is TSQL specific - here's the PLSQL equivalent to what you posted:

v_date1 DATE := TO_DATE('03-AUG-2010', 'DD-MON-YYYY');

SELECT u.visualid
  FROM USAGE u 
 WHERE u.usetime > v_date1;

There's also no need for prefixing variables with "@"; I tend to prefix variables with "v_" to distinguish between variables & columns/etc.

See this thread about the Oracle equivalent of NOLOCK...

Restart Netbeans & it solved my problem.

What is the datatype for column1 in your Hive table? Please note that if your column is STRING it won't be having a NULL value even though your external file does not have any data for that column.

We will import the CSV file into the destination table in the simplest form. I placed my sample CSV file on the C: drive and now we will create a table which we will import data from the CSV file.

DROP TABLE IF EXISTS Sales 

CREATE TABLE [dbo].[Sales](
    [Region] [varchar](50) ,
    [Country] [varchar](50) ,
    [ItemType] [varchar](50) NULL,
    [SalesChannel] [varchar](50) NULL,
    [OrderPriority] [varchar](50) NULL,
    [OrderDate]  datetime,
    [OrderID] bigint NULL,
    [ShipDate] datetime,
    [UnitsSold]  float,
    [UnitPrice] float,
    [UnitCost] float,
    [TotalRevenue] float,
    [TotalCost]  float,
    [TotalProfit] float
)

The following BULK INSERT statement imports the CSV file to the Sales table.

BULK INSERT Sales
FROM 'C:\1500000 Sales Records.csv'
WITH (FIRSTROW = 2,
    FIELDTERMINATOR = ',',
    ROWTERMINATOR='\n' );

WOOCOMMERCE ORDERS IN VERSION 3.0+

Since Woocommerce mega major Update 3.0+ things have changed quite a lot:

• For WC_Order Object, properties can't be accessed directly anymore as before and will throw some errors.
• New WC_Order and WC_Abstract_Order getter and setter methods are now required on the WC_Order object instance.
• Also, there are some New classes for Order items:
  • WC_Order_Item class,
  • WC_Order_Item_Product class,
  • WC_Order_Item_Tax class,
  • WC_Order_Item_Shipping class,
  • WC_Order_Item_Coupon class,
  • WC_Order_Item_Fee class.
• Additionally, WC_Data Abstract class allow to access Order and order items data using get_data(), get_meta_data() and get_meta() methods.

Related:
• How to get Customer details from Order in WooCommerce?
• Get Order items and WC_Order_Item_Product in WooCommerce 3

So the Order items properties will not be accessible as before in a foreach loop and you will have to use these specific getter and setter methods instead.

Using some WC_Order and WC_Abstract_Order methods (example):

// Get an instance of the WC_Order object (same as before)
$order = wc_get_order( $order_id );

$order_id  = $order->get_id(); // Get the order ID
$parent_id = $order->get_parent_id(); // Get the parent order ID (for subscriptions…)

$user_id   = $order->get_user_id(); // Get the costumer ID
$user      = $order->get_user(); // Get the WP_User object

$order_status  = $order->get_status(); // Get the order status (see the conditional method has_status() below)
$currency      = $order->get_currency(); // Get the currency used  
$payment_method = $order->get_payment_method(); // Get the payment method ID
$payment_title = $order->get_payment_method_title(); // Get the payment method title
$date_created  = $order->get_date_created(); // Get date created (WC_DateTime object)
$date_modified = $order->get_date_modified(); // Get date modified (WC_DateTime object)

$billing_country = $order->get_billing_country(); // Customer billing country

// ... and so on ...

For order status as a conditional method (where "the_targeted_status" need to be defined and replaced by an order status to target a specific order status):

if ( $order->has_status('completed') ) {
    // Do something
}

Get and access to the order data properties (in an array of values):

// Get an instance of the WC_Order object
$order = wc_get_order( $order_id );

$order_data = $order->get_data(); // The Order data

$order_id = $order_data['id'];
$order_parent_id = $order_data['parent_id'];
$order_status = $order_data['status'];
$order_currency = $order_data['currency'];
$order_version = $order_data['version'];
$order_payment_method = $order_data['payment_method'];
$order_payment_method_title = $order_data['payment_method_title'];
$order_payment_method = $order_data['payment_method'];
$order_payment_method = $order_data['payment_method'];

## Creation and modified WC_DateTime Object date string ##

// Using a formated date ( with php date() function as method)
$order_date_created = $order_data['date_created']->date('Y-m-d H:i:s');
$order_date_modified = $order_data['date_modified']->date('Y-m-d H:i:s');

// Using a timestamp ( with php getTimestamp() function as method)
$order_timestamp_created = $order_data['date_created']->getTimestamp();
$order_timestamp_modified = $order_data['date_modified']->getTimestamp();

$order_discount_total = $order_data['discount_total'];
$order_discount_tax = $order_data['discount_tax'];
$order_shipping_total = $order_data['shipping_total'];
$order_shipping_tax = $order_data['shipping_tax'];
$order_total = $order_data['total'];
$order_total_tax = $order_data['total_tax'];
$order_customer_id = $order_data['customer_id']; // ... and so on

## BILLING INFORMATION:

$order_billing_first_name = $order_data['billing']['first_name'];
$order_billing_last_name = $order_data['billing']['last_name'];
$order_billing_company = $order_data['billing']['company'];
$order_billing_address_1 = $order_data['billing']['address_1'];
$order_billing_address_2 = $order_data['billing']['address_2'];
$order_billing_city = $order_data['billing']['city'];
$order_billing_state = $order_data['billing']['state'];
$order_billing_postcode = $order_data['billing']['postcode'];
$order_billing_country = $order_data['billing']['country'];
$order_billing_email = $order_data['billing']['email'];
$order_billing_phone = $order_data['billing']['phone'];

## SHIPPING INFORMATION:

$order_shipping_first_name = $order_data['shipping']['first_name'];
$order_shipping_last_name = $order_data['shipping']['last_name'];
$order_shipping_company = $order_data['shipping']['company'];
$order_shipping_address_1 = $order_data['shipping']['address_1'];
$order_shipping_address_2 = $order_data['shipping']['address_2'];
$order_shipping_city = $order_data['shipping']['city'];
$order_shipping_state = $order_data['shipping']['state'];
$order_shipping_postcode = $order_data['shipping']['postcode'];
$order_shipping_country = $order_data['shipping']['country'];

Get the order items and access the data with WC_Order_Item_Product and WC_Order_Item methods:

// Get an instance of the WC_Order object
$order = wc_get_order($order_id);

// Iterating through each WC_Order_Item_Product objects
foreach ($order->get_items() as $item_key => $item ):

    ## Using WC_Order_Item methods ##

    // Item ID is directly accessible from the $item_key in the foreach loop or
    $item_id = $item->get_id();

    ## Using WC_Order_Item_Product methods ##

    $product      = $item->get_product(); // Get the WC_Product object

    $product_id   = $item->get_product_id(); // the Product id
    $variation_id = $item->get_variation_id(); // the Variation id

    $item_type    = $item->get_type(); // Type of the order item ("line_item")

    $item_name    = $item->get_name(); // Name of the product
    $quantity     = $item->get_quantity();  
    $tax_class    = $item->get_tax_class();
    $line_subtotal     = $item->get_subtotal(); // Line subtotal (non discounted)
    $line_subtotal_tax = $item->get_subtotal_tax(); // Line subtotal tax (non discounted)
    $line_total        = $item->get_total(); // Line total (discounted)
    $line_total_tax    = $item->get_total_tax(); // Line total tax (discounted)

    ## Access Order Items data properties (in an array of values) ##
    $item_data    = $item->get_data();

    $product_name = $item_data['name'];
    $product_id   = $item_data['product_id'];
    $variation_id = $item_data['variation_id'];
    $quantity     = $item_data['quantity'];
    $tax_class    = $item_data['tax_class'];
    $line_subtotal     = $item_data['subtotal'];
    $line_subtotal_tax = $item_data['subtotal_tax'];
    $line_total        = $item_data['total'];
    $line_total_tax    = $item_data['total_tax'];

    // Get data from The WC_product object using methods (examples)
    $product        = $item->get_product(); // Get the WC_Product object

    $product_type   = $product->get_type();
    $product_sku    = $product->get_sku();
    $product_price  = $product->get_price();
    $stock_quantity = $product->get_stock_quantity();

endforeach;

So using get_data() method allow us to access to the protected data (associative array mode) …

I had the same problem, and have not been able to get Eclipse in Windows 7 to recognise the device. The device is correctly configured, Windows 7 recognises it on the USB port, and I edited the Run settings in Eclipse to prompt for a device, and it is just not there.

I ran it with the following steps:

• Connect the device to the computer with USB.
• Ensure the device is not locked (ie. timed out in the UI). I have to keep unlocking it while I'm working.
• Wait for Windows to recognise the USB device, and when the autoplay menu comes up select Open device to view files. It should open up the file system in the device, in Explorer.
• In Explorer go to the Eclipse workspace and find the apk file from the build (eg. MyFirstApp.apk)
• Copy the apk file to the Downloads directory on the device
• On the device, use the My Files app (or similar) to open the Downloads directory.
• Click the downloaded file (My First App.apk) and Android offers to install it
• Select install
• The app is now in the installed Apps. Run it.

A second method is to mail the apk file to the device and then download and install it. (Credits to a post on SO which I can't find now).

A third method is to use DropBox. This requires installation of DropBox on the PC and on the device (from the play store) but once both are set up it runs very smoothly. Just share a DropBox folder between the two devices, and then drop the APK into that folder on the PC, and open it on the device. With this method you don't need a USB connection, and can also install the APK on multiple devices. It also assists the management of multiple development versions (by making a separate sub-folder for each version).

You can also copy a cell which contains the conditional formatting and then select the range (of destination document -or page-) where you want the conditional format to be applied and select "paste special" > "paste only conditional formatting"

textarea {
  white-space: pre;
  overflow-wrap: normal;
  overflow-x: scroll;
}

white-space: nowrap also works if you don't care about whitespace, but of course you don't want that if you're working with code (or indented paragraphs or any content where there might deliberately be multiple spaces) ... so i prefer pre.

overflow-wrap: normal (was word-wrap in older browsers) is needed in case some parent has changed that setting; it can cause wrapping even if pre is set.

also -- contrary to the currently accepted answer -- textareas do often wrap by default. pre-wrap seems to be the default on my browser.

Even though you've accepted an answer, I want to post this method. I use jQuery to center it vertically instead of css (although both of these methods work). Here is a fiddle, and I'll post the code here anyways.

HTML:

<h1>Hello world!</h1>

Javascript (jQuery):

$(document).ready(function(){
  $('h1').css({ 'width':'100%', 'text-align':'center' });
  var h1 = $('h1').height();
  var h = h1/2;
  var w1 = $(window).height();
  var w = w1/2;
  var m = w - h
  $('h1').css("margin-top",m + "px")
});

This takes the height of the viewport, divides it by two, subtracts half the height of the h1, and sets that number to the margin-top of the h1. The beauty of this method is that it works on multiple-line h1s.

EDIT: I modified it so that it centered it every time the window is resized.

As others have said, there is no universally correct block size; what is optimal for one situation or one piece of hardware may be terribly inefficient for another. Also, depending on the health of the disks it may be preferable to use a different block size than what is "optimal".

One thing that is pretty reliable on modern hardware is that the default block size of 512 bytes tends to be almost an order of magnitude slower than a more optimal alternative. When in doubt, I've found that 64K is a pretty solid modern default. Though 64K usually isn't THE optimal block size, in my experience it tends to be a lot more efficient than the default. 64K also has a pretty solid history of being reliably performant: You can find a message from the Eug-Lug mailing list, circa 2002, recommending a block size of 64K here: http://www.mail-archive.com/[email protected]/msg12073.html

For determining THE optimal output block size, I've written the following script that tests writing a 128M test file with dd at a range of different block sizes, from the default of 512 bytes to a maximum of 64M. Be warned, this script uses dd internally, so use with caution.

dd_obs_test.sh:

#!/bin/bash

# Since we're dealing with dd, abort if any errors occur
set -e

TEST_FILE=${1:-dd_obs_testfile}
TEST_FILE_EXISTS=0
if [ -e "$TEST_FILE" ]; then TEST_FILE_EXISTS=1; fi
TEST_FILE_SIZE=134217728

if [ $EUID -ne 0 ]; then
  echo "NOTE: Kernel cache will not be cleared between tests without sudo. This will likely cause inaccurate results." 1>&2
fi

I've only tested this script on a Debian (Ubuntu) system and on OSX Yosemite, so it will probably take some tweaking to make work on other Unix flavors.

By default the command will create a test file named dd_obs_testfile in the current directory. Alternatively, you can provide a path to a custom test file by providing a path after the script name:

$ ./dd_obs_test.sh /path/to/disk/test_file

The output of the script is a list of the tested block sizes and their respective transfer rates like so:

$ ./dd_obs_test.sh
block size : transfer rate
       512 : 11.3 MB/s
      1024 : 22.1 MB/s
      2048 : 42.3 MB/s
      4096 : 75.2 MB/s
      8192 : 90.7 MB/s
     16384 : 101 MB/s
     32768 : 104 MB/s
     65536 : 108 MB/s
    131072 : 113 MB/s
    262144 : 112 MB/s
    524288 : 133 MB/s
   1048576 : 125 MB/s
   2097152 : 113 MB/s
   4194304 : 106 MB/s
   8388608 : 107 MB/s
  16777216 : 110 MB/s
  33554432 : 119 MB/s
  67108864 : 134 MB/s

(Note: The unit of the transfer rates will vary by OS)

To test optimal read block size, you could use more or less the same process, but instead of reading from /dev/zero and writing to the disk, you'd read from the disk and write to /dev/null. A script to do this might look like so:

dd_ibs_test.sh:

#!/bin/bash

# Since we're dealing with dd, abort if any errors occur
set -e

TEST_FILE=${1:-dd_ibs_testfile}
if [ -e "$TEST_FILE" ]; then TEST_FILE_EXISTS=$?; fi
TEST_FILE_SIZE=134217728

# Exit if file exists
if [ -e $TEST_FILE ]; then
  echo "Test file $TEST_FILE exists, aborting."
  exit 1
fi
TEST_FILE_EXISTS=1

if [ $EUID -ne 0 ]; then
  echo "NOTE: Kernel cache will not be cleared between tests without sudo. This will likely cause inaccurate results." 1>&2
fi

# Create test file
echo 'Generating test file...'
BLOCK_SIZE=65536
COUNT=$(($TEST_FILE_SIZE / $BLOCK_SIZE))
dd if=/dev/urandom of=$TEST_FILE bs=$BLOCK_SIZE count=$COUNT conv=fsync > /dev/null 2>&1

do
  # Clear kernel cache to ensure more accurate test
  [ $EUID -eq 0 ] && [ -e /proc/sys/vm/drop_caches ] && echo 3 > /proc/sys/vm/drop_caches

  # Read test file out to /dev/null with specified block size
  DD_RESULT=$(dd if=$TEST_FILE of=/dev/null bs=$BLOCK_SIZE 2>&1 1>/dev/null)

An important difference in this case is that the test file is a file that is written by the script. Do not point this command at an existing file or the existing file will be overwritten with zeroes!

For my particular hardware I found that 128K was the most optimal input block size on a HDD and 32K was most optimal on a SSD.

Though this answer covers most of my findings, I've run into this situation enough times that I wrote a blog post about it: http://blog.tdg5.com/tuning-dd-block-size/ You can find more specifics on the tests I performed there.

To allow this to work with filenames using spaces, a modified version of the accepted answer is needed:

FOR /F "delims=" %%I IN ('DIR . /B /O:-D') DO COPY "%%I" <<NewDir>> & GOTO :END
:END

for i in count: means for i in 7:, which won't work. The bit after the in should be of an iterable type, not a number. Try this:

for i in range(count):

Correct attribute value for Asp.Net MVC Core to prevent browser caching (including Internet Explorer 11) is:

To use arrow functions with function.prototype.call, I made a helper function on the object prototype:

  // Using
  // @func = function() {use this here} or This => {use This here}
  using(func) {
    return func.call(this, this);
  }

usage

  var obj = {f:3, a:2}
  .using(This => This.f + This.a) // 5

Edit

You don't NEED a helper. You could do:

var obj = {f:3, a:2}
(This => This.f + This.a).call(undefined, obj); // 5

Actually, there appears to now be a simple way. The following code works in TypeScript 1.5:

function sayName({ first, last = 'Smith' }: {first: string; last?: string }): void {
  const name = first + ' ' + last;
  console.log(name);
}

sayName({ first: 'Bob' });

The trick is to first put in brackets what keys you want to pick from the argument object, with key=value for any defaults. Follow that with the : and a type declaration.

This is a little different than what you were trying to do, because instead of having an intact params object, you have instead have dereferenced variables.

If you want to make it optional to pass anything to the function, add a ? for all keys in the type, and add a default of ={} after the type declaration:

function sayName({first='Bob',last='Smith'}: {first?: string; last?: string}={}){
    var name = first + " " + last;
    alert(name);
}

sayName();

You can do it programmatically:

grid0.Columns[0].Visible = true;
grid0.DataSource = dt;
grid0.DataBind();
grid0.Columns[0].Visible = false;

In this way you set the column to visible before databinding, so the column is generated. The you set the column to not visible, so it is not displayed.

Another approach is to disable the text box on the client side.

In your case you have only one textbox that you need to disable but consider the case where you have multiple input, select, and textarea fields that yout need to disable.

It is much easier to do it via jquery + (since we can not rely on data coming from the client) add some logic to the controller to prevent these fields from being saved.

Here is an example:

<input id="document_Status" name="document.Status" type="hidden" value="2" />

$(document).ready(function () {

    disableAll();
}

function disableAll() {
  var status = $('#document_Status').val();

  if (status != 0) {
      $("input").attr('disabled', true);
      $("textarea").attr('disabled', true);
      $("select").attr('disabled', true);
  }
}

Dictionary<,> is the equivalent. While it doesn't have a Get(...) method, it does have an indexed property called Item which you can access in C# directly using index notation:

class Test {
  Dictionary<int,String> entities;

  public String getEntity(int code) {
    return this.entities[code];
  }
}

If you want to use a custom key type then you should consider implementing IEquatable<> and overriding Equals(object) and GetHashCode() unless the default (reference or struct) equality is sufficient for determining equality of keys. You should also make your key type immutable to prevent weird things happening if a key is mutated after it has been inserted into a dictionary (e.g. because the mutation caused its hash code to change).

To change the default "sub-menu" class name, there is simple way. You can just change it in wordpress file.

location : www/project_name/wp-includes/nav-menu-template.php.

open this file and at line number 49, change the name of sub-menu class with your custom class.

Or you can also add your custom class next to sub-menu.

Done.

It worked for me.I used wordpress-4.4.1.

If you use a Container as the body of the Scaffold, its size will be accordingly the size of its child, and usually that is not what you want when you try to add a background image to your app.

Looking at this other question, @collin-jackson was also suggesting to use Stack instead of Container as the body of the Scaffold and it definitely does what you want to achieve.

This is how my code looks like

@override
Widget build(BuildContext context) {
  return new Scaffold(
    body: new Stack(
      children: <Widget>[
        new Container(
          decoration: new BoxDecoration(
            image: new DecorationImage(image: new AssetImage("images/background.jpg"), fit: BoxFit.cover,),
          ),
        ),
        new Center(
          child: new Text("Hello background"),
        )
      ],
    )
  );
}

It depends on context. There a lot benefits that are appropriate to dynamic typed system as well as for strong typed. I'm of opinion that the flow of dynamic types language is faster. The dynamic languages are not constrained with class attributes and compiler thinking of what is going on in code. You have some kinda freedom. Furthermore, the dynamic language usually is more expressive and result in less code which is good. Despite of this, it's more error prone which is also questionable and depends more on unit test covering. It's easy prototype with dynamic lang but maintenance may become nightmare.

The main gain over static typed system is IDE support and surely static analyzer of code. You become more confident of code after every code change. The maintenance is peace of cake with such tools.

If these are elements naturally in the tab order like buttons and anchors, removing them from the tab order with tabindex="-1" is kind of an accessibility smell. If they're providing duplicate functionality removing them from the tab order is ok, and consider adding aria-hidden="true" to these elements so assistive technologies will ignore them.

Assuming your 'time' column has at least one observation with a non-numeric character and all your other columns only have numbers, then 'read.csv's default will be to read in 'time' as a 'factor' and all the rest of the columns as 'numeric'. Therefore setting 'stringsAsFactors=F' will have the same result as setting the 'colClasses' manually i.e.,

data <- read.csv('test.csv', stringsAsFactors=F)

Here is the msdn documentation on the listview object and the listviewItem object.
http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.aspx
http://msdn.microsoft.com/en-us/library/system.windows.forms.listviewitem.aspx

I would highly recommend that you at least take the time to skim the documentation on any objects you use from the .net framework. While the documentation can be pretty poor at some times it is still invaluable especially when you run into situations like this.

But as James Atkinson said it's simply a matter of adding subitems to a listviewitem like so:

ListViewItem i = new ListViewItem("column1");
i.SubItems.Add("column2");
i.SubItems.Add("column3");

Your broadcast receiver must specify android:exported="true" to receive broadcasts created outside your own application. My broadcast receiver is defined in the manifest as follows:

<receiver
    android:name=".IncomingSmsBroadcastReceiver"
    android:enabled="true"
    android:exported="true" >
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

As noted below, exported="true" is the default, so you can omit this line. I've left it in so that the discussion comments make sense.

At the risk of echoing every other answer, no, you cannot mix them in the same project.

That aside, if you just finished converting VB to C#, why would you write new code in VB?

Just setup UIBarButtonItem with customView

For example:

  var leftNavBarButton = UIBarButtonItem(customView:yourButton)
  self.navigationItem.leftBarButtonItem = leftNavBarButton

or use setFunction:

  self.navigationItem.setLeftBarButtonItem(UIBarButtonItem(customView: yourButton), animated: true);

You can use the ListAvailable option of Get-Module:

if (Get-Module -ListAvailable -Name SomeModule) {
    Write-Host "Module exists"
} 
else {
    Write-Host "Module does not exist"
}

Just turn off notifications for the default sms app. Process your own notifications for all text messages!

• Add the jar file to your WEB-INF/lib folder.
• Right-click your project in Eclipse, and go to "Build Path > Configure Build Path"
• Add the "Web App Libraries" library

This will ensure all WEB-INF/lib jars are included on the classpath.

Better use the project Cron in combination with the Linux cronjob for this task. It allows you to configure run times in your PHP Code, support background jobs and is easy to use.

First step call a PHP Script every minute:

* * * * * /usr/local/bin/run.php &> /dev/null

Second Step use the cron/cron Package to configure run times directly in PHP.

$deprecatedStatus = new ShellJob();
$deprecatedStatus->setCommand('cd /app && /usr/local/bin/php cron/updateDeprecatedStatus.php');
$deprecatedStatus->setSchedule(new CrontabSchedule('* * * * */2'));


$displayDate = new ShellJob();
$displayDate->setCommand('cd /app && /usr/local/bin/php cron/updateDisplayDate.php');
$displayDate->setSchedule(new CrontabSchedule('* * * * */5'));

You found the details how to use in the linked repository.

You can use the Collections API to achieve what you want easily - read efficiently - enough Javadoc for Collections.max

Collections.max(arrayList);

Returns the maximum element of the given collection, according to the natural ordering of its elements. All elements in the collection must implement the Comparable interface.

Well, I think it would be a bad idea to replicate the code which is already present in classes like SimpleDateFormat.

On the other hand, personally I'd suggest avoiding Calendar and Date entirely if you can, and using Joda Time instead, as a far better designed date and time API. For example, you need to be aware that SimpleDateFormat is not thread-safe, so you either need thread-locals, synchronization, or a new instance each time you use it. Joda parsers and formatters are thread-safe.

-num will equal to num for Integer.MIN_VALUE as

 Integer.MIN_VALUE =  Integer.MIN_VALUE * -1

let me start by stating the facts:

Syntax:
string.slice(start,end)
string.substr(start,length)
string.substring(start,end)
Note #1: slice()==substring()

What it does?
The slice() method extracts parts of a string and returns the extracted parts in a new string.
The substr() method extracts parts of a string, beginning at the character at the specified position, and returns the specified number of characters.
The substring() method extracts parts of a string and returns the extracted parts in a new string.
Note #2:slice()==substring()

Changes the Original String?
slice() Doesn't
substr() Doesn't
substring() Doesn't
Note #3:slice()==substring()

Using Negative Numbers as an Argument:
slice() selects characters starting from the end of the string
substr()selects characters starting from the end of the string
substring() Doesn't Perform
Note #3:slice()==substr()

if the First Argument is Greater than the Second:
slice() Doesn't Perform
substr() since the Second Argument is NOT a position, but length value, it will perform as usual, with no problems
substring() will swap the two arguments, and perform as usual

the First Argument:
slice() Required, indicates: Starting Index
substr() Required, indicates: Starting Index
substring() Required, indicates: Starting Index
Note #4:slice()==substr()==substring()

the Second Argument:
slice() Optional, The position (up to, but not including) where to end the extraction
substr() Optional, The number of characters to extract
substring() Optional, The position (up to, but not including) where to end the extraction
Note #5:slice()==substring()

What if the Second Argument is Omitted?
slice() selects all characters from the start-position to the end of the string
substr() selects all characters from the start-position to the end of the string
substring() selects all characters from the start-position to the end of the string
Note #6:slice()==substr()==substring()

so, you can say that there's a difference between slice() and substr(), while substring() is basically a copy of slice().

in Summary:
if you know the index(the position) on which you'll stop (but NOT include), Use slice()
if you know the length of characters to be extracted use substr().

This script will add a div that covers the entire window as the page loads. It will show a CSS-only loading spinner automatically. It will wait until the window (not the document) finishes loading, then it will wait an optional extra few seconds.

• Works with jQuery 3 (it has a new window load event)
• No image needed but it's easy to add one
• Change the delay for more branding or instructions
• Only dependency is jQuery.

I figured out that I was not generating Credentials for the right app type.
If you're using Postman to test Google oAuth 2 APIs, select
Credentials -> Add credentials -> OAuth2.0 client ID -> Web Application.

1. First, launch your Safari browser from the Home screen and go to the webpage that you want to view full screen.

2. After locating the webpage, tap on the arrow icon at the top of your screen.

3. In the drop-down menu, tap on the Add to Home Screen option.

4. The Add to Home window should be displayed. You can customize the description that will appear as a title on the home screen of your iPad. When you are done, tap on the Add button.

5. A new icon should now appear on your home screen. Tapping on the icon will open the webpage in the fullscreen mode.

Note: The icon on your iPad home screen only opens the bookmarked page in the fullscreen mode. The next page you visit will be contain the Safari address and title bars. This way of playing your webpage or HTML5 presentation in the fullscreen mode works if the source code of the webpage contains the following tag:

<meta name="apple-mobile-web-app-capable" content="yes">

You can add this tag to your webpage using a third-party tool, for example iWeb SEO Tool or any other you like. Please note that you need to add the tag first, refresh the page and then add a bookmark to your home screen.

Then just modify the previous answers to:

Console.Write(strToProcess.Replace("@", "@" + Environment.NewLine));

If you don't want the newlines in the text file, then don't preserve it.

A little late to the party, but here's another solution.

Simply adjusting the class of the modal to something like alert-danger does work, however it removes the top rounded corners of the modal.

A workaround is to give the element with modal-header an additional class of panel-heading, e.g.

<div class="modal fade" tabindex="-1" role="dialog">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header panel-heading"> <!-- change here -->
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
        <p>One fine body&hellip;</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

Then, to change the heading color you can do something like (assuming you're using jQUery)

jQuery('.modal-content').addClass('panel-danger')

.val() always works with textarea elements.

.text() works sometimes and fails other times! It's not reliable (tested in Chrome 33)

What's best is that .val() works seamlessly with other form elements too (like input) whereas .text() fails.

Flurry Support for iPhone 5 (ARMv7s) As I mentioned in yesterday’s post, Flurry started working on a version of the iOS SDK to support the ARMv7s processor in the new iPhone 5 immediately after the announcement on Wednesday.

I am happy to tell you that the work is done and the SDK is now available on the site.

use Result Rows.
row() method returns a single result row.

$id = $this 
    -> db
    -> select('id')
    -> where('email', $email)
    -> limit(1)
    -> get('users')
    -> row();

then, you can simply use as you want. :)

echo "ID is" . $id;

Pass float to sleep, like sleep 0.1

Here's an example of creating and using an event with C#

using System;

namespace Event_Example
{
    //First we have to define a delegate that acts as a signature for the
    //function that is ultimately called when the event is triggered.
    //You will notice that the second parameter is of MyEventArgs type.
    //This object will contain information about the triggered event.
    public delegate void MyEventHandler(object source, MyEventArgs e);

    //This is a class which describes the event to the class that recieves it.
    //An EventArgs class must always derive from System.EventArgs.
    public class MyEventArgs : EventArgs
    {
        private string EventInfo;
        public MyEventArgs(string Text)
        {
            EventInfo = Text;
        }
        public string GetInfo()
        {
            return EventInfo;
        }
    }

    //This next class is the one which contains an event and triggers it
    //once an action is performed. For example, lets trigger this event
    //once a variable is incremented over a particular value. Notice the
    //event uses the MyEventHandler delegate to create a signature
    //for the called function.
    public class MyClass
    {
        public event MyEventHandler OnMaximum;
        private int i;
        private int Maximum = 10;
        public int MyValue
        {
            get
            {
                return i;
            }
            set
            {
                if(value <= Maximum)
                {
                    i = value;
                }
                else
                {
                    //To make sure we only trigger the event if a handler is present
                    //we check the event to make sure it's not null.
                    if(OnMaximum != null)
                    {
                        OnMaximum(this, new MyEventArgs("You've entered " +
                            value.ToString() +
                            ", but the maximum is " +
                            Maximum.ToString()));
                    }
                }
            }
        }

Be careful when accessing DateTime.Now twice, as it's possible for the calls to straddle midnight and you'll get wacky results on rare occasions and be left scratching your head.

To be safe, you should assign DateTime.Now to a local variable first if you're going to use it more than once:

var now = DateTime.Now;
var time = now.ToString("hh:mm:ss tt");
var date = now.ToString("MM/dd/yy");

Note the use of lower case "hh" do display hours from 00-11 even in the afternoon, and "tt" to show AM/PM, as the question requested. If you want 24 hour clock 00-23, use "HH".

Is this what youre looking for? I did it with jQuery!

TurboByte

Another powershell method (I only wanted failures)

$ping = new-object System.Net.NetworkInformation.Ping
$target="192.168.0.1"
Write-Host "$(Get-Date -format 's') Start ping to $target"
while($true){
    $reply = $ping.send($target)
    if ($reply.status -eq "Success"){
        # ignore success    
        Start-Sleep -Seconds 1
    }
    else{
        Write-Host "$(Get-Date -format 's') Destination unreachable" $target

    }
}

const grid = Array.from(Array(3), e => Array(4));

Array.from(arrayLike, mapfn)

mapfn is called, being passed the value undefined, returning new Array(4).

An iterator is created and the next value is repeatedly called. The value returned from next, next().value is undefined. This value, undefined, is then passed to the newly-created array's iterator. Each iteration's value is undefined, which you can see if you log it.

var grid2 = Array.from(Array(3), e => {
  console.log(e); // undefined
  return Array(4); // a new Array.
});

The ! should be around the outside of the statement:

data[!(data$v1 %in% c("b", "d", "e")), ]

  v1 v2 v3 v4
1  a  v  d  c
2  a  v  d  d
5  c  k  d  c
6  c  r  p  g

You can do by using a custom middleware, even though knowing that the best option is using the tested approach of the package django-cors-headers. With that said, here is the solution:

create the following structure and files:

-- myapp/middleware/__init__.py

from corsMiddleware import corsMiddleware

-- myapp/middleware/corsMiddleware.py

class corsMiddleware(object):
    def process_response(self, req, resp):
        resp["Access-Control-Allow-Origin"] = "*"
        return resp

add to settings.py the marked line:

MIDDLEWARE_CLASSES = (
    "django.contrib.sessions.middleware.SessionMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.middleware.csrf.CsrfViewMiddleware",

    # Now we add here our custom middleware
     'app_name.middleware.corsMiddleware' <---- this line
)

Compiling and running a Java application on Mac OSX, or any major operating system, is very easy. Apple includes a fully-functional Java runtime and development environment out-of-the-box with OSX, so all you have to do is write a Java program and use the built-in tools to compile and run it.

Writing Your First Program

The first step is writing a simple Java program. Open up a text editor (the built-in TextEdit app works fine), type in the following code, and save the file as "HelloWorld.java" in your home directory.

public class HelloWorld {
    public static void main(String args[]) {
        System.out.println("Hello World!");
    }
}

For example, if your username is David, save it as "/Users/David/HelloWorld.java". This simple program declares a single class called HelloWorld, with a single method called main. The main method is special in Java, because it is the method the Java runtime will attempt to call when you tell it to execute your program. Think of it as a starting point for your program. The System.out.println() method will print a line of text to the screen, "Hello World!" in this example.

Using the Compiler

Now that you have written a simple Java program, you need to compile it. Run the Terminal app, which is located in "Applications/Utilities/Terminal.app". Type the following commands into the terminal:

cd ~
javac HelloWorld.java

You just compiled your first Java application, albeit a simple one, on OSX. The process of compiling will produce a single file, called "HelloWorld.class". This file contains Java byte codes, which are the instructions that the Java Virtual Machine understands.

Running Your Program

To run the program, type the following command in the terminal.

java HelloWorld

This command will start a Java Virtual Machine and attempt to load the class called HelloWorld. Once it loads that class, it will execute the main method I mentioned earlier. You should see "Hello World!" printed in the terminal window. That's all there is to it.

As a side note, TextWrangler is just a text editor for OSX and has no bearing on this situation. You can use it as your text editor in this example, but it is certainly not necessary.

In my case

In Application Pool i set .NetFrameWork version to V4.0 and solved problem ....

Make the keydown even call multiple functions, with each function checking for a specific key and responding appropriately.

document.keydown = function (key) {

    checkKey("x");
    checkKey("y");
};

This is impossible as you cannot return from an asynchronous call inside a synchronous method.

In this case you need to pass a callback to foo that will receive the return value

function foo(address, fn){
  geocoder.geocode( { 'address': address}, function(results, status) {
     fn(results[0].geometry.location); 
  });
}

foo("address", function(location){
  alert(location); // this is where you get the return value
});

The thing is, if an inner function call is asynchronous, then all the functions 'wrapping' this call must also be asynchronous in order to 'return' a response.

If you have a lot of callbacks you might consider taking the plunge and use a promise library like Q.

Just use getActionBar().hide(); in your main activity onCreate() method.

Angular 2 and Angular 4 

In a ngFor loop it must be look like this:

<div class="column" *ngFor="let u of events ">
                <div class="thumb">
                    <img src="assets/uploads/{{u.image}}">
                    <h4>{{u.name}}</h4>
                </div>
                <div class="info">
                    <img src="assets/uploads/{{u.image}}">
                    <h4>{{u.name}}</h4>
                    <p>{{u.text}}</p>
                </div>
            </div>

The VH unit can be used to fill the background of the viewport, aka the browser window.

(height:100vh;)

html{
    height:100%;
    }
.body {
     background: url(image.jpg) no-repeat center top; 
     background-size: cover; 
     height:100vh;     
}

The External Dependencies folder is populated by IntelliSense: the contents of the folder do not affect the build at all (you can in fact disable the folder in the UI).

You need to actually include the header (using a #include directive) to use it. Depending on what that header is, you may also need to add its containing folder to the "Additional Include Directories" property and you may need to add additional libraries and library folders to the linker options; you can set all of these in the project properties (right click the project, select Properties). You should compare the properties with those of the project that does build to determine what you need to add.

Missing ; after var_dump($row)

You just need a binary (with debugging symbols included) that is identical to the one that generated the core dump file. Then you can run gdb path/to/the/binary path/to/the/core/dump/file to debug it.

When it starts up, you can use bt (for backtrace) to get a stack trace from the time of the crash. In the backtrace, each function invocation is given a number. You can use frame number (replacing number with the corresponding number in the stack trace) to select a particular stack frame.

You can then use list to see code around that function, and info locals to see the local variables. You can also use print name_of_variable (replacing "name_of_variable" with a variable name) to see its value.

Typing help within GDB will give you a prompt that will let you see additional commands.

You can use a Scanner and its nextInt() method.
Scanner also has nextLong() for larger integers, if needed.

There is yet an another way to add interceptors in your OkHttp3 (latest version as of now) , that is you add the interceptors to your Okhttp builder

okhttpBuilder.networkInterceptors().add(chain -> {
 //todo add headers etc to your AuthorisedRequest

  return chain.proceed(yourAuthorisedRequest);
});

and finally build your okHttpClient from this builder

OkHttpClient client = builder.build();

Use database column nullble() in Laravel. You can choose the default value or nullable value in database.

Bit of a late response but I noticed that this information can be hard to find and haven't found the answer on SO, so here it is.

Try a differnt parameter #view=FitH to force it to fit in the horzontal space and also you need to start the querystring off with a # rather than an & making it:

filename.pdf#view=FitH

What I've noticed it is that this will work if adobe reader is embedded in the browser but chrome will use it's own version of the reader and won't respond in the same way. In my own case, the chrome browser zoomed to fit width by default, so no problem , but Internet Explorer needed the above parameters to ensure the link always opened the pdf page with the correct view setting.

For a full list of available parameters see this doc

EDIT: (lazy mode on)

Get the router from the container.

$router = $this->get('router');

Then use the router to generate the Url

$uri = $router->generate('blog_show', array('slug' => 'my-blog-post'));

I found that inserting \\n works. I.e., you escape the escaped new line character

Your web.xml ends with <web-app>, but must end with </web-app>

Which by the way is almost literally what the exception tells you.

restorecon command works as below :

restorecon -v -R /var/www/html/

After fixing the build.gradle version, It started working 4.0.0 to 3.5.0

var_str = str()
var_int = int()

Rather than try to target @media rules at specific devices, it is arguably more practical to base them on your particular layout instead. That is, gradually narrow your desktop browser window and observe the natural breakpoints for your content. It's different for every site. As long as the design flows well at each browser width, it should work pretty reliably on any screen size (and there are lots and lots of them out there.)

Solution

Use this code

jQuery.nl2br = function(varTest){
  return varTest.replace(/(\r\n|\n\r|\r|\n)/g, "<br>");
};

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

        //set up notitle 
        requestWindowFeature(Window.FEATURE_NO_TITLE);  
        //set up full screen
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,   
                WindowManager.LayoutParams.FLAG_FULLSCREEN);  

        setContentView(R.layout.main);  
} 

You can use case-sensitive or case-insensitive comparison, depending what you need. Case-sensitive is like this:

if ([category isEqualToString:@"Some String"])
{
   // Both strings are equal without respect to their case.
}

Case-insensitive is like this:

if ([category compare:@"Some String" options:NSCaseInsensitiveSearch] == NSOrderedSame)
{
   // Both strings are equal with respect to their case.
}

In urlip3 there's no .urlopen, instead try this:

import requests
html = requests.get(url)

OpenSSL is quite difficult. It's easy to accidentally throw away all your security by not doing negotiation exactly right. (Heck, I've been personally bitten by a bug where curl wasn't reading the OpenSSL alerts exactly right, and couldn't talk to some sites.)

If you really want quick and simple, put stud in front of your program an call it a day. Having SSL in a different process won't slow you down: http://vincent.bernat.im/en/blog/2011-ssl-benchmark.html

In v1.43 is the ability to separately color the vertical rulers.

See issue Support multiple rulers with different colors - (in settings.json):

"editor.rulers": [
  {
    "column": 80,
    "color": "#ff00FF"
  },
  100,  // <- a ruler in the default color or as customized (with "editorRuler.foreground") at column 100
  {
    "column": 120,
    "color": "#ff0000"

Shallow copies duplicate as little as possible. A shallow copy of a collection is a copy of the collection structure, not the elements. With a shallow copy, two collections now share the individual elements.

Deep copies duplicate everything. A deep copy of a collection is two collections with all of the elements in the original collection duplicated.

Check out Pathname and in particular Pathname#exist?.

File and its FileTest module are perhaps simpler/more direct, but I find Pathname a nicer interface in general.

Reverse the string and check if original string and reverse are same or not

This blog post seems to have your answer: http://blog.capstrat.com/articles/facebook-share-thumbnail-image/

Specifically, use a tag like the following:

<link rel="image_src" 
      type="image/jpeg" 
      href="http://www.domain.com/path/icon-facebook.gif" />

The name of the image must be the same as in the example.

Note: Tags can be correct but Facebook only scrapes every 24 hours, according to their documentation. Use the Facebook Lint page to get the image into Facebook.

The short version: Arrays are mostly faster than objects. But there is no 100% correct solution.

Original Post - Explanation

There are some misconceptions in your question.

There are no associative arrays in Javascript. Only Arrays and Objects.

These are arrays:

var a1 = [1, 2, 3];
var a2 = ["a", "b", "c"];
var a3 = [];
a3[0] = "a";
a3[1] = "b";
a3[2] = "c";

This is an array, too:

var a3 = [];
a3[29938] = "a";
a3[32994] = "b";

It's basically an array with holes in it, because every array does have continous indexing. It's slower than arrays without holes. But iterating manually through the array is even slower (mostly).

This is an object:

var a3 = {};
a3[29938] = "a";
a3[32994] = "b";

Here is a performance test of three possibilities:

Lookup Array vs Holey Array vs Object Performance Test

You need to apply the following CSS property to the container block (div):

overflow-wrap: break-word;

According to the specifications (source CSS | MDN):

The overflow-wrap CSS property specifies whether or not the browser should insert line breaks within words to prevent text from overflowing its content box.

With the value set to break-word

To prevent overflow, normally unbreakable words may be broken at arbitrary points if there are no otherwise acceptable break points in the line.

Worth mentioning...

The property was originally a nonstandard and unprefixed Microsoft extension called word-wrap, and was implemented by most browsers with the same name. It has since been renamed to overflow-wrap, with word-wrap being an alias.

If you care about legacy browsers support it's worth specifying both:

word-wrap    : break-word;
overflow-wrap: break-word;

Ex. IE9 does not recognize overflow-wrap but works fine with word-wrap

When you compare update_date >= '2013-05-03' postgres casts values to the same type to compare values. So your '2013-05-03' was casted to '2013-05-03 00:00:00'.

So for update_date = '2013-05-03 14:45:00' your expression will be that:

'2013-05-03 14:45:00' >= '2013-05-03 00:00:00' AND '2013-05-03 14:45:00' <= '2013-05-03 00:00:00'

This is always false

To solve this problem cast update_date to date:

select * from table where update_date::date >= '2013-05-03' AND update_date::date <= '2013-05-03' -> Will return result

re (as in regular expressions) allows splitting on multiple characters at once:

$ string = "blah, lots  ,  of ,  spaces, here "
$ re.split(', ',string)
['blah', 'lots  ', ' of ', ' spaces', 'here ']

This doesn't work well for your example string, but works nicely for a comma-space separated list. For your example string, you can combine the re.split power to split on regex patterns to get a "split-on-this-or-that" effect.

$ re.split('[, ]',string)
['blah',
 '',
 'lots',
 '',
 '',
 '',
 '',
 'of',
 '',
 '',
 '',
 'spaces',
 '',
 'here',
 '']

Unfortunately, that's ugly, but a filter will do the trick:

$ filter(None, re.split('[, ]',string))
['blah', 'lots', 'of', 'spaces', 'here']

Voila!

All you need to do is pass the JspWriter object into your method as a parameter i.e.

void someOutput(JspWriter stream)

Then call it via:

<% someOutput(out) %>

The writer object is a local variable inside _jspService so you need to pass it into your utility method. The same would apply for all the other built in references (e.g. request, response, session).

A great way to see whats going on is to use Tomcat as your server and drill down into the 'work' directory for the '.java' file generated from your 'jsp' page. Alternatively in weblogic you can use the 'weblogic.jspc' page compiler to view the Java that will be generated when the page is requested.

Here is a java 8 method to find a string in a text file:

for (String toFindUrl : urlsToTest) {
        streamService(toFindUrl);
    }

private void streamService(String item) {
        try (Stream<String> stream = Files.lines(Paths.get(fileName))) {
           stream.filter(lines -> lines.contains(item))
                       .forEach(System.out::println);

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

While the answer above is correct I would not recommend you to change the name in order to rely on it in the code.

Names are tricky. They can change. You should use the ShapeId and SlideId.

Especially beware to change the name of a shape programmatically since PowerPoint relies on the name and it might hinder its regular operation.

$.each($("#MySelect option"), function(){
                    alert($(this).text() + " - " + $(this).val());                    
                });

This solution should work fine, it's easy :

jQuery(document).ready(function($) {
    jQuery(document).click(function(event) {
        if(typeof  jQuery(event.target).attr("class") != "undefined") {
            var classnottobeclickforclose = ['donotcountmeforclickclass1', 'donotcountmeforclickclass2','donotcountmeforclickclass3'];
            var arresult = jQuery.inArray(jQuery(event.target).attr("class"), classnottobeclickforclose);
            if (arresult < 0) {
                jQuery(".popup").hide();
            }
        }
    });
});

In Above code change donotcountmeforclickclass1 , donotcountmeforclickclass2 etc with classes which you have used to show popup or on it's click popup should not effect so you have to definitely add class which you are using to open popup.

Change .popup class with popup class.

You could use the ArrayUtils API to remove it in a "nice looking way". It implements many operations (remove, find, add, contains,etc) on Arrays.
Take a look. It has made my life simpler.

You could define a function using model_to_dict as follows:

def queryset_to_list(qs,fields=None, exclude=None):
    my_list=[]
    for x in qs:
        my_list.append(model_to_dict(x,fields=fields,exclude=exclude))
    return my_list

Suppose your Model has following fields

id
name
email

Run following commands in django shell

>>>qs=<yourmodel>.objects.all()
>>>list=queryset_to_dict(qs)
>>>list
[{'id':1, 'name':'abc', 'email':'[email protected]'},{'id':2, 'name':'xyz', 'email':'[email protected]'}]

Say you want only id and name in the list of queryset dictionary

>>>qs=<yourmodel>.objects.all()
>>>list=queryset_to_dict(qs,fields=['id','name'])
>>>list
[{'id':1, 'name':'abc'},{'id':2, 'name':'xyz'}]

Similarly you can exclude fields in your output.

Future version of node will allow you to fork a process and pass messages to it and Ryan has stated he wants to find some way to also share file handlers, so it won't be a straight forward Web Worker implementation.

At this time there is not an easy solution for this but it's still very early and node is one of the fastest moving open source projects I've ever seen so expect something awesome in the near future.

I had this problem with WebDAV when hosting a MVC4 WebApi Project. I got around it by adding this line to the web.config:

<handlers>
  <remove name="WebDAV" />
  <add name="WebDAV" path="*" verb="*" modules="WebDAVModule"
      resourceType="Unspecified" requireAccess="None" />
</handlers>

As explained here: http://evolutionarydeveloper.blogspot.co.uk/2012/07/method-not-allowed-405-on-iis7-website.html

if you are getting error this(535, b'5.7.8 Username and Password not accepted. Learn more at\n5.7.8 https://support.google.com/mail/?p=BadCredentials o60sm2132303pje.21 - gsmtp')

then simply go in you google accountsettings of security section and make a less secure account and turn on the less secure button

I also had to remove the SMSS before it would get past that step.

ApplicationContext (Root Application Context) : Every Spring MVC web application has an applicationContext.xml file which is configured as the root of context configuration. Spring loads this file and creates an applicationContext for the entire application. This file is loaded by the ContextLoaderListener which is configured as a context param in web.xml file. And there will be only one applicationContext per web application.

WebApplicationContext : WebApplicationContext is a web aware application context i.e. it has servlet context information. A single web application can have multiple WebApplicationContext and each Dispatcher servlet (which is the front controller of Spring MVC architecture) is associated with a WebApplicationContext. The webApplicationContext configuration file *-servlet.xml is specific to a DispatcherServlet. And since a web application can have more than one dispatcher servlet configured to serve multiple requests, there can be more than one webApplicationContext file per web application.

It might be that the code in your service somehow breaks out of Angular's zone. This breaks change detection. This should work:

import {Component, OnInit, NgZone} from 'angular2/core';

export class RecentDetectionComponent implements OnInit {

    recentDetections: Array<RecentDetection>;

    constructor(private zone:NgZone, // <== added
        private recentDetectionService: RecentDetectionService) {
        this.recentDetections = new Array<RecentDetection>();
    }

    getRecentDetections(): void {
        this.recentDetectionService.getJsonFromApi()
            .subscribe(recent => {

        });
    }

    ngOnInit() {
        this.getRecentDetections();
        let timer = Observable.timer(2000, 5000);
        timer.subscribe(() => this.getRecentDetections());
    }
}

For other ways to invoke change detection see Triggering change detection manually in Angular

Alternative ways to invoke change detection are

ChangeDetectorRef.detectChanges()

to immediately run change detection for the current component and its children

ChangeDetectorRef.markForCheck()

to include the current component the next time Angular runs change detection

ApplicationRef.tick()

to run change detection for the whole application

if you want to know the install version of Xcode as well as Swift language current version:

Use below simple command by using Terminal:

1. To get install Xcode Version

 xcodebuild -version

2. To get install Swift language Version

swift --version

I had this issue after upgrading to the Eclipse 2019-12 release. Somehow the command line to launch the JVM got too long and I had to enable the jar-classpath option in the run configuration (right click on file -> run as -> run configs).

Another option is to use the TimeUtils utility method:

TimeUtils.millisToUnit(System.currentTimeMillis(), TimeUnit.SECONDS)

In the examples below the client is the browser and the server is the webserver hosting the website.

Before you can understand these technologies, you have to understand classic HTTP web traffic first.

Regular HTTP:

1. A client requests a webpage from a server.
2. The server calculates the response
3. The server sends the response to the client.

Ajax Polling:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which requests a file from the server at regular intervals (e.g. 0.5 seconds).
3. The server calculates each response and sends it back, just like normal HTTP traffic.

Ajax Long-Polling:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which requests a file from the server.
3. The server does not immediately respond with the requested information but waits until there's new information available.
4. When there's new information available, the server responds with the new information.
5. The client receives the new information and immediately sends another request to the server, re-starting the process.

HTML5 Server Sent Events (SSE) / EventSource:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which opens a connection to the server.

3. The server sends an event to the client when there's new information available.

   • Real-time traffic from server to client, mostly that's what you'll need
   • You'll want to use a server that has an event loop
   • Connections with servers from other domains are only possible with correct CORS settings
   • If you want to read more, I found these very useful: (article), (article), (article), (tutorial).

HTML5 Websockets:

1. A client requests a webpage from a server using regular http (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which opens a connection with the server.

3. The server and the client can now send each other messages when new data (on either side) is available.

   • Real-time traffic from the server to the client and from the client to the server
   • You'll want to use a server that has an event loop
   • With WebSockets it is possible to connect with a server from another domain.
   • It is also possible to use a third party hosted websocket server, for example Pusher or others. This way you'll only have to implement the client side, which is very easy!
   • If you want to read more, I found these very useful: (article), (article) (tutorial).

Comet:

Comet is a collection of techniques prior to HTML5 which use streaming and long-polling to achieve real time applications. Read more on wikipedia or this article.

Now, which one of them should I use for a realtime app (that I need to code). I have been hearing a lot about websockets (with socket.io [a node.js library]) but why not PHP ?

You can use PHP with WebSockets, check out Ratchet.

Looking at the source code I also think there must be some issue with the private key.

What it is doing is actually to check if the certificate that is passed is of type X509Certificate2 and if it has the private key.

If it doesn't find the private key it tries to find the certificate in the CurrentUser store and then in the LocalMachine store. If it finds the certificate it checks if the private key is present.

(see source code from class SecureChannnel, method EnsurePrivateKey)

So depending on which file you imported (.cer - without private key or .pfx - with private key) and on which store it might not find the right one and Request.ClientCertificate won't be populated.

You can activate Network Tracing to try to debug this. It will give you output like this:

• Trying to find a matching certificate in the certificate store
• Cannot find the certificate in either the LocalMachine store or the CurrentUser store.

This is what I typically do:

File outputDir = context.getCacheDir(); // context being the Activity pointer
File outputFile = File.createTempFile("prefix", "extension", outputDir);

As for their deletion, I am not complete sure either. Since I use this in my implementation of a cache, I manually delete the oldest files till the cache directory size comes down to my preset value.

Functional programming is about creating side-effect-free code.

map is a functional list transformation abstraction. You use it to take a sequence of something and turn it into a sequence of something else.

You are trying to use it as an iterator. Don't do that. :)

Here is an example of how you might use map to build the list you want. There are shorter solutions (I'd just use comprehensions), but this will help you understand what map does a bit better:

def my_transform_function(input):
    return [input, [1, 2, 3]]

new_list = map(my_transform, input_list)

Notice at this point, you've only done a data manipulation. Now you can print it:

for n,l in new_list:
    print n, ll

-- I'm not sure what you mean by 'without loops.' fp isn't about avoiding loops (you can't examine every item in a list without visiting each one). It's about avoiding side-effects, thus writing fewer bugs.

Building on Roland's answer, using tidyr to reshape the data from wide to long:

library(tidyr)
library(ggplot2)

df <- read.table(text="Rank F1     F2     F3
1    500    250    50
2    400    100    30
3    300    155    100
4    200    90     10", header=TRUE)

df %>% 
  gather(variable, value, F1:F3) %>% 
  ggplot(aes(x = Rank, y = value, fill = variable)) + 
  geom_bar(stat = "identity")

You don't need to escape the ' character in a String (wrapped in "), and you don't have to escape a " character in a char (wrapped in ').

Yes you can do the following.

[[float(y) for y in x] for x in l]

try this.

    background-color: #aaa;
}

tbody 
{
    background-color: #ddd;

    overflow-y: scroll;
    position: absolute;
}

{
    padding: 3px 10px;

do this:

$("tr.item").each(function(i, tr) {
    var value = $("span.value", tr).text();
    var quantity = $("input.quantity", tr).val();
});

document.title was not working for me.

Here is another way to do it using JQuery

$('html head').find('title').text("My New Page Title");

Depends on what you run in that thread. If that's your code, then you can implement a stop condition (see other answers).

However, if what you want is to run someone else's code, then you should fork and start a process. Like this:

import multiprocessing
proc = multiprocessing.Process(target=your_proc_function, args=())
proc.start()

now, whenever you want to stop that process, send it a SIGTERM like this:

proc.terminate()
proc.join()

And it's not slow: fractions of a second. Enjoy :)

Here's how I understand it:

What percent does x lie in a range

Let's assume you have a range from 0 to 100. Given an arbitrary number from that range, what "percent" from that range does it lie in? This should be pretty simple, 0 would be 0%, 50 would be 50% and 100 would be 100%.

Now, what if your range was 20 to 100? We cannot apply the same logic as above (divide by 100) because:

20 / 100

doesn't give us 0 (20 should be 0% now). This should be simple to fix, we just need to make the numerator 0 for the case of 20. We can do that by subtracting:

(20 - 20) / 100

However, this doesn't work for 100 anymore because:

(100 - 20) / 100

doesn't give us 100%. Again, we can fix this by subtracting from the denominator as well:

(100 - 20) / (100 - 20)

A more generalized equation for finding out what % x lies in a range would be:

(x - MIN) / (MAX - MIN)

Scale range to another range

Now that we know what percent a number lies in a range, we can apply it to map the number to another range. Let's go through an example.

old range = [200, 1000]
new range = [10, 20]

If we have a number in the old range, what would the number be in the new range? Let's say the number is 400. First, figure out what percent 400 is within the old range. We can apply our equation above.

(400 - 200) / (1000 - 200) = 0.25

So, 400 lies in 25% of the old range. We just need to figure out what number is 25% of the new range. Think about what 50% of [0, 20] is. It would be 10 right? How did you arrive at that answer? Well, we can just do:

20 * 0.5 = 10

But, what about from [10, 20]? We need to shift everything by 10 now. eg:

((20 - 10) * 0.5) + 10

a more generalized formula would be:

((MAX - MIN) * PERCENT) + MIN

To the original example of what 25% of [10, 20] is:

((20 - 10) * 0.25) + 10 = 12.5

So, 400 in the range [200, 1000] would map to 12.5 in the range [10, 20]

TLDR

To map x from old range to new range:

OLD PERCENT = (x - OLD MIN) / (OLD MAX - OLD MIN)
NEW X = ((NEW MAX - NEW MIN) * OLD PERCENT) + NEW MIN

'%f' % (x/y)

but you need to manage precision yourself. e.g.,

'%f' % (1/10**8)

will display zeros only.
details are in the docs

Or for Python 3 the equivalent old formatting or the newer style formatting

You need only one line before the declaration of the class Animal for correct polymorphic serialization/deserialization:

@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = JsonTypeInfo.As.PROPERTY, property = "@class")
public abstract class Animal {
   ...
}

This line means: add a meta-property on serialization or read a meta-property on deserialization (include = JsonTypeInfo.As.PROPERTY) called "@class" (property = "@class") that holds the fully-qualified Java class name (use = JsonTypeInfo.Id.CLASS).

So, if you create a JSON directly (without serialization) remember to add the meta-property "@class" with the desired class name for correct deserialization.

I wanted a different look of my website for width screen and small screen. I have made 2 CSS files. In Java I choose which of the 2 CSS file is used depending on the screen width. I use the PHP function echo with in the echo-function some javascript.

my code in the <header> section of my PHP-file:

<?php
echo "
<script>
    if ( window.innerWidth > 400)
            { document.write('<link href=\"kekemba_resort_stylesheetblog-jun2018.css\" rel=\"stylesheet\" type=\"text/css\">'); }
    else
            { document.write('<link href=\"kekemba_resort_stylesheetblog-jun2018small.css\" rel=\"stylesheet\" type=\"text/css\">'); }
</script>
"; 
?>

Simply you can aadd --force at the end of the command. Like:

sudo docker rmi <docker_image_id> --force

To make it more intelligent you can add as:

sudo docker stop $(docker ps | grep <your_container_name> | awk '{print $1}')

sudo docker rm $(docker ps | grep <your_container_name> | awk '{print $1}')

sudo docker rmi $(docker images | grep <your_image_name> | awk '{print $3}') --force

Here in docker ps $1 is the first column, i.e. the Docker container ID.

And docker images $3 is the third column, i.e. the Docker image ID.

This is off the cuff, but isn't that what Grasshopper was for?

$("#vp_code").textinput("enable");
$("#vp_code").textinput("disable");

Starting in API 21 the notion of weight was added to GridLayout.

To support older android devices, you can use the GridLayout from the v7 support library.

compile 'com.android.support:gridlayout-v7:22.2.1'

The following XML gives an example of how you can use weights to fill the screen width.

<?xml version="1.0" encoding="utf-8"?>

Check out the ReadKey() method on the System.Console .NET class. I think that will do what you're looking for.

http://msdn.microsoft.com/en-us/library/system.console.readkey(v=vs.110).aspx

Example:

Write-Host -Object ('The key that was pressed was: {0}' -f [System.Console]::ReadKey().Key.ToString());

If you only want to remove columns 5 and 7 but not 6 try:

album2 <- album2[,-c(5,7)] #deletes columns 5 and 7

Specify the property (i.e. colour) where you want the filter to be applied:

<div ng-repeat="product in products | filter:{ colour: by_colour }">

Like Ray Toal mentioned it is as easy as:

Set<String> myConcurrentSet = ConcurrentHashMap.newKeySet();

The assembly was introduced with .NET 3.5 and is in the GAC.

Simply add a .NET reference to your project.

Project -> Right Click References -> Select .NET tab -> System.Web.Extensions

If it is not there, you need to install .NET 3.5 or 4.0.

A cookie key(used to identify a session) and a cookie are the same thing being used in different ways. So the limit would be the same. According to Microsoft its 4096 bytes.

MSDN

cookies are usually limited to 4096 bytes and you can't store more than 20 cookies per site. By using a single cookie with subkeys, you use fewer of those 20 cookies that your site is allotted. In addition, a single cookie takes up about 50 characters for overhead (expiration information, and so on), plus the length of the value that you store in it, all of which counts toward the 4096-byte limit. If you store five subkeys instead of five separate cookies, you save the overhead of the separate cookies and can save around 200 bytes.

You forgot to do source bin/activate where source is a executable name. Struck me first few times as well, easy to think that manual is telling "execute this from root of the environment folder".

No need to make activate executable via chmod.

I created an AdaptiveTabLayout class to achieve this. This was the only way I found to actually solve the problem, answer the question and avoid/workaround problems that other answers here don't.

Notes:

• Handles phone/tablet layouts.
• Handles cases where there's enough room for MODE_SCROLLABLE but not enough room for MODE_FIXED. If you don't handle this case it's gonna happen on some devices you'll see different text sizes or oven two lines of text in some tabs, which looks bad.
• It gets real measures and doesn't make any assumptions (like screen is 360dp wide or whatever...). This works with real screen sizes and real tab sizes. This means works well with translations because doesn't assume any tab size, the tabs get measure.
• Deals with the different passes on the onLayout phase in order to avoid extra work.
• Layout width needs to be wrap_content on the xml. Don't set any mode or gravity on the xml.

AdaptiveTabLayout.java

    }

    public AdaptiveTabLayout(@NonNull final Context context, @Nullable final AttributeSet attrs)

        this(context, attrs, 0);
    }

    public AdaptiveTabLayout

    {
        super.onLayout(changed, l, t, r, b);

        if (mGravityAndModeSeUpNeeded)
        {
            setModeAndGravity();
        }
    }

    private void setModeAndGravity()
    {
        final int tabCount = getTabCount();
        final int screenWidth = UtilsDevice.getScreenWidth();
        final int minWidthNeedForMixedMode = getMinSpaceNeededForFixedMode(tabCount);

        if (minWidthNeedForMixedMode == 0)
        {
            return;
        }
        else if (minWidthNeedForMixedMode < screenWidth)
        {
            setTabMode(MODE_FIXED);
            setTabGravity(UtilsDevice.isBigTablet() ? GRAVITY_CENTER : GRAVITY_FILL) ;
        }
        else
        {
            setTabMode(TabLayout.MODE_SCROLLABLE);
        }

        setLayoutParams(new LinearLayout.LayoutParams
                (LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));

        mGravityAndModeSeUpNeeded = false;
    }

    private int getMinSpaceNeededForFixedMode(final int tabCount)

            currentWidth = linearLayout.getChildAt(i).getWidth();

            if (currentWidth == 0) return 0;

            if (currentWidth > widestTab)
            {

            }
        }

        return widestTab * tabCount;
    }

}

And this is the DeviceUtils class:

import android.content.res.Resources;

public class UtilsDevice extends Utils
{
    private static final int sWIDTH_FOR_BIG_TABLET_IN_DP = 720;

    private UtilsDevice() {}

    public static int pixelToDp(final int pixels)
    {
        return (int) (pixels / Resources.getSystem().getDisplayMetrics().density);
    }

    public static int getScreenWidth()
    {
        return Resources
                .getSystem()
                .getDisplayMetrics()
                .widthPixels;
    }

    public static boolean isBigTablet()
    {
        return pixelToDp(getScreenWidth()) >= sWIDTH_FOR_BIG_TABLET_IN_DP;
    }

}

How to find out what this MySQL Error is trying to say:

#1064 - You have an error in your SQL syntax;

This error has no clues in it. You have to double check all of these items to see where your mistake is:

1. You have omitted, or included an unnecessary symbol: !@#$%^&*()-_=+[]{}\|;:'",<>/?
2. A misplaced, missing or unnecessary keyword: select, into, or countless others.
3. You have unicode characters that look like ascii characters in your query but are not recognized.
4. Misplaced, missing or unnecessary whitespace or newlines between keywords.
5. Unmatched single quotes, double quotes, parenthesis or braces.

Take away as much as you can from the broken query until it starts working. And then use PostgreSQL next time that has a sane syntax reporting system.

after running different aforementioned functions for factorial, by different people, turns out that math.factorial is the fastest to calculate the factorial.

find running times for different functions in the attached image

A variation on your idea is to have a server-side USER-AGENT detector that will figure out what style sheet to attach to the page. This way you can have a firefox.css, ie.css, opera.css, etc.

You can accomplish a similar thing in Javascript itself, although you may not regard it as clean.

I have done a similar thing by having a default.css which includes all common styles and then specific style sheets are added to override, or enhance the defaults.

export default affects the syntax when importing the exported "thing", when allowing to import, whatever has been exported, by choosing the name in the import itself, no matter what was the name when it was exported, simply because it's marked as the "default".

A useful use case, which I like (and use), is allowing to export an anonymous function without explicitly having to name it, and only when that function is imported, it must be given a name:

Example:

Export 2 functions, one is default:

export function divide( x ){
    return x / 2;
}

// only one 'default' function may be exported and the rest (above) must be named
export default function( x ){  // <---- declared as a default function
    return x * x;
}

Import the above functions. Making up a name for the default one:

// The default function should be the first to import (and named whatever)
import square, {divide} from './module_1.js'; // I named the default "square" 

console.log( square(2), divide(2) ); // 4, 1

When the {} syntax is used to import a function (or variable) it means that whatever is imported was already named when exported, so one must import it by the exact same name, or else the import wouldn't work.

Erroneous Examples:

1. The default function must be first to import

   import {divide}, square from './module_1.js
   

2. divide_1 was not exported in module_1.js, thus nothing will be imported

   import {divide_1} from './module_1.js
   

3. square was not exported in module_1.js, because {} tells the engine to explicitly search for named exports only.

   import {square} from './module_1.js
   

using Linq would be:

 listOfCompany.Where(c=> c.id == 1).FirstOrDefault().Name = "Whatever Name";

UPDATE

This can be simplified to be...

 listOfCompany.FirstOrDefault(c=> c.id == 1).Name = "Whatever Name";

UPDATE

For multiple items (condition is met by multiple items):

 listOfCompany.Where(c=> c.id == 1).ToList().ForEach(cc => cc.Name = "Whatever Name");

    import java.sql.ResultSet;
    import java.sql.SQLException;
    import javax.swing.JOptionPane;
    import org.sqlite.SQLiteDataSource;
    import org.sqlite.SQLiteJDBCLoader;

    public class Test {

        public static final boolean Connected() {
            boolean initialize = SQLiteJDBCLoader.initialize();

            SQLiteDataSource dataSource = new SQLiteDataSource();
            dataSource.setUrl("jdbc:sqlite:/home/users.sqlite");
            int i=0;
            try {
                ResultSet executeQuery = dataSource.getConnection()
                        .createStatement().executeQuery("select * from \"Table\"");
                while (executeQuery.next()) {
i++;
                    System.out.println("out: "+executeQuery.getMetaData().getColumnLabel(i));

                }



            } catch (SQLException ex) {
                JOptionPane.showMessageDialog(null, ex);
            }

            return initialize;

        }

The most compact version:

<input type="submit" onclick="return confirm('Are you sure?')" />

The key thing to note is the return

-

Because there are many ways to skin a cat, here is another alternate method:

HTML:

<input type="submit" onclick="clicked(event)" />

Javascript:

<script>
function clicked(e)
{
    if(!confirm('Are you sure?')) {
        e.preventDefault();
    }
}
</script>

A good reason is for security - this can prevent CSRF attacks because this header cannot be added to the AJAX request cross domain without the consent of the server via CORS.

Only the following headers are allowed cross domain:

• Accept
• Accept-Language
• Content-Language
• Last-Event-ID
• Content-Type

any others cause a "pre-flight" request to be issued in CORS supported browsers.

Without CORS it is not possible to add X-Requested-With to a cross domain XHR request.

If the server is checking that this header is present, it knows that the request didn't initiate from an attacker's domain attempting to make a request on behalf of the user with JavaScript. This also checks that the request wasn't POSTed from a regular HTML form, of which it is harder to verify it is not cross domain without the use of tokens. (However, checking the Origin header could be an option in supported browsers, although you will leave old browsers vulnerable.)

New Flash bypass discovered

You may wish to combine this with a token, because Flash running on Safari on OSX can set this header if there's a redirect step. It appears it also worked on Chrome, but is now remediated. More details here including different versions affected.

OWASP Recommend combining this with an Origin and Referer check:

This defense technique is specifically discussed in section 4.3 of Robust Defenses for Cross-Site Request Forgery. However, bypasses of this defense using Flash were documented as early as 2008 and again as recently as 2015 by Mathias Karlsson to exploit a CSRF flaw in Vimeo. But, we believe that the Flash attack can't spoof the Origin or Referer headers so by checking both of them we believe this combination of checks should prevent Flash bypass CSRF attacks. (NOTE: If anyone can confirm or refute this belief, please let us know so we can update this article)

However, for the reasons already discussed checking Origin can be tricky.

Update

Written a more in depth blog post on CORS, CSRF and X-Requested-With here.

You are right. This is a badly documented issue. But you can change the font size parameter (by opposition to font scale) directly after building the plot. Check the following example:

import seaborn as sns
tips = sns.load_dataset("tips")

b = sns.boxplot(x=tips["total_bill"])
b.axes.set_title("Title",fontsize=50)
b.set_xlabel("X Label",fontsize=30)
b.set_ylabel("Y Label",fontsize=20)
b.tick_params(labelsize=5)
sns.plt.show()

, which results in this:

To make it consistent in between plots I think you just need to make sure the DPI is the same. By the way it' also a possibility to customize a bit the rc dictionaries since "font.size" parameter exists but I'm not too sure how to do that.

NOTE: And also I don't really understand why they changed the name of the font size variables for axis labels and ticks. Seems a bit un-intuitive.

If you docker registry is private and self hosted you should do the following :

docker login <REGISTRY_HOST>:<REGISTRY_PORT>
docker tag <IMAGE_ID> <REGISTRY_HOST>:<REGISTRY_PORT>/<APPNAME>:<APPVERSION>
docker push <REGISTRY_HOST>:<REGISTRY_PORT>/<APPNAME>:<APPVERSION>

Example :

docker login repo.company.com:3456
docker tag 19fcc4aa71ba repo.company.com:3456/myapp:0.1
docker push repo.company.com:3456/myapp:0.1

Construct the first parameter as an instance of Action, e.g.

var inputID = 123;
var col = new BlockingDataCollection();
var task = Task.Factory.StartNew(
    () => CheckFiles(inputID, col),
    cancelCheckFile.Token,
    TaskCreationOptions.LongRunning,
    TaskScheduler.Default);

The below code worked for me.

I've created a method for seekbar

@Override
public void onPrepared(MediaPlayer mediaPlayer) {
    mp.start();
     getDurationTimer();
    getSeekBarStatus();


}
//Creating duration time method
public void getDurationTimer(){
    final long minutes=(mSongDuration/1000)/60;
    final int seconds= (int) ((mSongDuration/1000)%60);
    SongMaxLength.setText(minutes+ ":"+seconds);


}



 //creating a method for seekBar progress
public void getSeekBarStatus(){

    new Thread(new Runnable() {

        @Override
        public void run() {
            // mp is your MediaPlayer
            // progress is your ProgressBar

            int currentPosition = 0;
            int total = mp.getDuration();
            seekBar.setMax(total);
            while (mp != null && currentPosition < total) {
                try {
                    Thread.sleep(1000);
                    currentPosition = mp.getCurrentPosition();
                } catch (InterruptedException e) {
                    return;
                }
                seekBar.setProgress(currentPosition);

            }
        }
    }).start();





    seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        int progress=0;

        @Override
        public void onProgressChanged(final SeekBar seekBar, int ProgressValue, boolean fromUser) {
            if (fromUser) {
                mp.seekTo(ProgressValue);//if user drags the seekbar, it gets the position and updates in textView.
            }
            final long mMinutes=(ProgressValue/1000)/60;//converting into minutes
            final int mSeconds=((ProgressValue/1000)%60);//converting into seconds
            SongProgress.setText(mMinutes+":"+mSeconds);
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

        }
    });
}

SongProgress and SongMaxLength are the TextView to show song duration and song length.

Alt+F4 is working only in brackets

It follows the convention that static methods should be thread-safe, but actually in v2 that static api is a proxy to an instance method on a default instance: in the case protobuf-net, it internally minimises contention points, and synchronises the internal state when necessary. Basically the library goes out of its way to do things right so that you can have simple code.

You can use the following solution:

s="jack"

tup=tuple(s.split(" "))

output=('jack')

At your parent DIV add

display:table;

and at your child element add

 display:table-cell;
 vertical-align:middle;

This link works with me: video

The answer posted before didn't work for me until the second click

So what I did is Directly call:

        new NewForm().setVisible(true);

        this.dispose();//to close the current jframe

use the className property:

document.getElementById('your_element_s_id').className = 'cssClass';

Check for missing folders that are required by the server, in my case it was UPLOADS folder in programData which was deleted by empty folder cleaner utility that I used earlier.

How did I find out:

run the server config file my.ini(in my case it was in programData) as the defaults-file param for mysqld (don't forget to use --console option to view error log on screen) 'mysqld --defaults-file="C:\ProgramData\MySQL\MySQL Server 8.0\my.ini" --console'

Error:

mysqld: Can't read dir of 'C:\ProgramData\MySQL\MySQL Server 8.0\Uploads\' (OS errno 2 - No such file or directory)

Solution:

Once I manually created the Uploads folder the server started successfully.

The best way to do it is:

String path = "C:" + File.separator + "hello" + File.separator + "hi.txt";
// Use relative path for Unix systems
File f = new File(path);

f.getParentFile().mkdirs(); 
f.createNewFile();

What fixed it for me was

1. stopping the instance
2. creating a backup of the .mdf and .ldf files in the data folder
3. Restart the instance
4. delete the database stuck restoring
5. put the .mdf and.ldf files back into the data folder
6. Attach the instance to the .mdf and .ldf files

Wouldn't it be better to have an array with

arr[0] = "blah"
arr[1] = "foo"
arr[2] = "bar"

and do return arr[something];?

If it's about the practice in general, you should keep the break statements in the switch. In the event that you don't need return statements in the future, it lessens the chance it will fall through to the next case.

Set the minOccurs attribute to 0 in the schema like so:

<?xml version="1.0"?>
  <xs:schema version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
    <xs:element name="request">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="amenity">
                    <xs:complexType>
                        <xs:sequence>
                            <xs:element name="description" type="xs:string" minOccurs="0" />
                        </xs:sequence>
                    </xs:complexType>
                </xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element> </xs:schema>

Everybody mentioned a constructor call through an initialization list, but nobody said that a parent class's constructor can be called explicitly from the derived member's constructor's body. See the question Calling a constructor of the base class from a subclass' constructor body, for example. The point is that if you use an explicit call to a parent class or super class constructor in the body of a derived class, this is actually just creating an instance of the parent class and it is not invoking the parent class constructor on the derived object. The only way to invoke a parent class or super class constructor on a derived class' object is through the initialization list and not in the derived class constructor body. So maybe it should not be called a "superclass constructor call". I put this answer here because somebody might get confused (as I did).

Just a quick addition to @TimGilbert's old-school answer...you can make your abstract base class's init() method throw an exception and that would prevent it from being instantiated, no?

>>> class Abstract(object):
...     def __init__(self):
...         raise NotImplementedError("You can't instantiate this class!")
...
>>> a = Abstract()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in __init__
NotImplementedError: You can't instantiate this class! 

I use

<div th:text ="${variable != null} ? (${variable != ''} ? ${variable} : 'empty string message') : 'null message' "></div>

I know some things have changed in AC 2010. However, the old-fashioned ADODB is, as far as I know, the best way to go in VBA. An Example:

Dim colReturn As New Collection

Dim SQL As String

    "SELECT c.ClientID, c.LastName, c.FirstName, c.MI, c.DOB, c.SSN, " & _
    "c.RaceID, c.EthnicityID, c.GenderID, c.Deleted, c.RecordDate " & _
    "FROM tblClient AS c " & _
    "WHERE c.ClientID = @ClientID"

Set cn = New ADODB.Connection
Set cmd = New ADODB.Command

With cn
    .Provider = DataConnection.MyADOProvider
    .ConnectionString = DataConnection.MyADOConnectionString
    .Open
End With

With cmd
    .CommandText = SQL
    .ActiveConnection = cn
    Set prm = .CreateParameter("@ClientID", adInteger, adParamInput, , mlngClientID)
    .Parameters.Append prm
End With

Set rs = cmd.Execute

With rs
    If Not .EOF Then
        Do Until .EOF

            mstrMI = Nz(!MI, "")
            mdDOB = !DOB

            mlngRaceID = Nz(!RaceID, -1)
            mlngEthnicityID = Nz(!EthnicityID, -1)

In addition to what @abarnert said, I today had to find out that the default cpio utility on Mountain Lion uses a different archive format per default (not sure which), even with the man page stating it would use the old cpio/odc format. So, if anyone stumbles upon the cpio read error: bad file format message while trying to install his/her manipulated packages, be sure to include the format in the re-pack step:

find ./Foo.app | cpio -o --format odc | gzip -c > Payload

FIDDLE

http://jsfiddle.net/8gC3D/471/

When you have related tables you often have one-to-many or many-to-many relationships. So when you join to TableB each record in TableA many have multiple records in TableB. This is normal and expected.

Now at times you only need certain columns and those are all the same for all the records, then you would need to do some sort of group by or distinct to remove the duplicates. Let's look at an example:

TableA
Id Field1
1  test
2  another test

TableB
ID Field2 field3
1  Test1  something
1  test1  More something
2  Test2  Anything

So when you join them and select all the files you get:

select * 
from tableA a 
join tableb b on a.id = b.id

a.Id a.Field1        b.id   b.field2  b.field3
1    test            1      Test1     something
1    test            1      Test1     More something
2    another test 2  2      Test2     Anything

These are not duplicates because the values of Field3 are different even though there are repeated values in the earlier fields. Now when you only select certain columns the same number of records are being joined together but since the columns with the different information is not being displayed they look like duplicates.

select a.Id, a.Field1,  b.field2
from tableA a 
join tableb b on a.id = b.id

a.Id a.Field1       b.field2  
1    test           Test1     
1    test           Test1 
2    another test   Test2

This appears to be duplicates but it is not because of the multiple records in TableB.

You normally fix this by using aggregates and group by, by using distinct or by filtering in the where clause to remove duplicates. How you solve this depends on exactly what your business rule is and how your database is designed and what kind of data is in there.

jQuery(document).ready(function () {
        jQuery('.select-all').on('change', function () {
            if (jQuery(this).is(':checked')) {
                jQuery('input.class-name').each(function () {
                    this.checked = true;
                });
            } else {
                jQuery('input.class-name').each(function () {
                    this.checked = false;
                });
            }

    });

You can also do it like:

This answer still comes up high in the list for ORA-12899 and lot of non helpful comments above, even if they are old. The most helpful comment was #4 for any professional trying to find out why they are getting this when loading data.

Some characters are more than 1 byte in length, especially true on SQL Server. And what might fit in a varchar(20) in SQLServer won't fit into a similar varchar2(20) in Oracle.

I ran across this error yesterday with SSIS loading an Oracle database with the Attunity drivers and thought I would save folks some time.

var values = new [] {"abc", "def", "ghj"};
var str = "abcedasdkljre";
values.Any(str.Contains);

I know this is old, but most of these answers require a ton of extra code.

If you have a light colored background, you can simply use this:

android:elevation="25dp"

Simple Solution:

JsonElement element = new JsonParser().parse(new InputStreamReader(inputStream));
JSONObject jsonObject = new JSONObject(element.getAsJsonObject().toString());

You can even set a separate right margin for HTML. Under the specified path:

This is very useful because generally HTML and JS may be usually long in one line than Python. :)

I prefer to work with the PSDrive WSMan:\.

Get TrustedHosts

Get-Item WSMan:\localhost\Client\TrustedHosts

Set TrustedHosts

provide a single, comma-separated, string of computer names

Set-Item WSMan:\localhost\Client\TrustedHosts -Value 'machineA,machineB'

or (dangerous) a wild-card

Set-Item WSMan:\localhost\Client\TrustedHosts -Value '*'

to append to the list, the -Concatenate parameter can be used

Set-Item WSMan:\localhost\Client\TrustedHosts -Value 'machineC' -Concatenate

You are pretty confused my friend. There are no LOOPS in SQL, only in PL/SQL. Here's a few examples based on existing Oracle table - copy/paste to see results:

-- Numeric FOR loop --
set serveroutput on -->> do not use in TOAD --
DECLARE
  k NUMBER:= 0;
BEGIN
  FOR i IN 1..10 LOOP
    k:= k+1;
    dbms_output.put_line(i||' '||k);
 END LOOP;
END;
/

-- Cursor FOR loop --
set serveroutput on
DECLARE
   CURSOR c1 IS SELECT * FROM scott.emp;
   i NUMBER:= 0;
BEGIN
  FOR e_rec IN c1 LOOP
  i:= i+1;
    dbms_output.put_line(i||chr(9)||e_rec.empno||chr(9)||e_rec.ename);
  END LOOP;
END;
/

-- SQL example to generate 10 rows --
SELECT 1 + LEVEL-1 idx
  FROM dual
CONNECT BY LEVEL <= 10
/

It's a shame that we need multiple ARG too, it results in multiple layers and slows down the build because of that, and for anyone also wondering that, currently there is no way to set multiple ARGs.

The below answer is no more relevant to present day.

So for any one looking for answers you should look at the documentation linked below

https://developer.android.com/training/articles/user-data-ids

Old Answer - Not relevant now. You check this blog in the link below

http://android-developers.blogspot.in/2011/03/identifying-app-installations.html

ANDROID_ID

import android.provider.Settings.Secure;

private String android_id = Secure.getString(getContext().getContentResolver(),
                                                    Secure.ANDROID_ID); 

The above is from the link @ Is there a unique Android device ID?

More specifically, Settings.Secure.ANDROID_ID. This is a 64-bit quantity that is generated and stored when the device first boots. It is reset when the device is wiped.

ANDROID_ID seems a good choice for a unique device identifier. There are downsides: First, it is not 100% reliable on releases of Android prior to 2.2 (“Froyo”). Also, there has been at least one widely-observed bug in a popular handset from a major manufacturer, where every instance has the same ANDROID_ID.

The below solution is not a good one coz the value survives device wipes (“Factory resets”) and thus you could end up making a nasty mistake when one of your customers wipes their device and passes it on to another person.

You get the imei number of the device using the below

  TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
  telephonyManager.getDeviceId();

http://developer.android.com/reference/android/telephony/TelephonyManager.html#getDeviceId%28%29

Add this is manifest

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

Firstly, if you are doing this just to prevent people viewing the source of your page - it won't work, because they can always use a keyboard shortcut to view it.

Secondly, you will have to use JavaScript to accomplish this. If the user has JS disabled, you cannot prevent the right click.

That said, add this to your body tag to disable right clicks.

<body oncontextmenu="return false;">

You need to use some JavaScript stuff to show your map. OpenLayers is the number one choice for this.

There is an example at http://wiki.openstreetmap.org/wiki/OpenLayers_Simple_Example and something more advanced at

http://wiki.openstreetmap.org/wiki/OpenLayers_Marker

and

http://wiki.openstreetmap.org/wiki/Openlayers_POI_layer_example

Adding @WebAppConfiguration (org.springframework.test.context.web.WebAppConfiguration) annotation to your DemoApplicationTests class will work.

It looks like your client is trying to connect to a non-existent server. In a shell window, run:

$ nc -l 5000

before running your Python code. It will act as a server listening on port 5000 for you to connect to. Then you can play with typing into your Python window and seeing it appear in the other terminal and vice versa.

It's not a direct answer to the question but you could just use the OR-operator

( grep "#SystemMaxUse=" journald.conf > /dev/null && sed -i 's/\#SystemMaxUse=/SystemMaxUse=50M/g' journald.conf ) || echo "This file has been edited. You'll need to do it manually."

I just ran into this issue, on the gpg CLI in Arch Linux. I needed to kill the existing "gpg-agent" process, then everything was back to normal ( a new gpg-agent should auto-launch when you invoke the gpg command, again; ...).

• edit: if the process fails to reload (e.g. within a minute), type gpg-agent in a terminal and/or reboot ...

bool IsDigitsOnly(string str)
{
    foreach (char c in str)
    {
        if (c < '0' || c > '9')
            return false;
    }

    return true;
}

Will probably be the fastest way to do it.

In C++ it is done like this:

#define LOCAL_PI 3.1415926535897932385 

double ToRadians(double degrees) 
{
  double radians = degrees * LOCAL_PI / 180;
  return radians;
}

double DirectDistance(double lat1, double lng1, double lat2, double lng2) 
{
  double earthRadius = 3958.75;
  double dLat = ToRadians(lat2-lat1);
  double dLng = ToRadians(lng2-lng1);
  double a = sin(dLat/2) * sin(dLat/2) + 
             cos(ToRadians(lat1)) * cos(ToRadians(lat2)) * 
             sin(dLng/2) * sin(dLng/2);
  double c = 2 * atan2(sqrt(a), sqrt(1-a));
  double dist = earthRadius * c;
  double meterConversion = 1609.00;
  return dist * meterConversion;
}

to convert to lower case is equivalent to rise bit 0x60 if you restrict yourself to ASCII:

for(char *p = pstr; *p; ++p)
    *p = *p > 0x40 && *p < 0x5b ? *p | 0x60 : *p;

i wrote this sp to create automatically the schema with all things, pk, fk, partitions, constraints... I wrote it to run in same sp.

Use a List (where T is any type or Object) when you want to add/remove data, since resizing arrays is expensive. You can read more about Arrays considered somewhat harmful whereas a List can be added to New records can be appended to the end. It adjusts its size as needed.

A List can be initalized in following ways

Using collection initializer.

List<string> list1 = new List<string>()
{
    "carrot",
    "fox",
    "explorer"
};

Using var keyword with collection initializer.

var list2 = new List<string>()
{
    "carrot",
    "fox",
    "explorer"
};

Using new array as parameter.

string[] array = { "carrot", "fox", "explorer" };
List<string> list3 = new List<string>(array);

Using capacity in constructor and assign.

List<string> list4 = new List<string>(3);
list4.Add(null); // Add empty references. (Not Recommended)
list4.Add(null);
list4.Add(null);
list4[0] = "carrot"; // Assign those references.
list4[1] = "fox";
list4[2] = "explorer";

Using Add method for each element.

List<string> list5 = new List<string>();
list5.Add("carrot");
list5.Add("fox");
list5.Add("explorer");

Thus for an Object List you can allocate and assign the properties of objects inline with the List initialization. Object initializers and collection initializers share similar syntax.

class Test
{
    public int A { get; set; }
    public string B { get; set; }
}

Initialize list with collection initializer.

List<Test> list1 = new List<Test>()
{
    new Test(){ A = 1, B = "Jessica"},
    new Test(){ A = 2, B = "Mandy"}
};

Initialize list with new objects.

List<Test> list2 = new List<Test>();
list2.Add(new Test() { A = 3, B = "Sarah" });
list2.Add(new Test() { A = 4, B = "Melanie" });

dplyr

packages is always a saver in case of data wrangling. To add the desired division as a third variable I would use mutate()

d <- mutate(d, new = min / count2.freq)

Link your custom.css file as the last entry below the bootstrap.css. Custom.css style definitions will override bootstrap.css

Html

<link href="css/bootstrap.min.css" rel="stylesheet">
<link href="css/custom.css" rel="stylesheet">

Copy all style definitions of legend in custom.css and make changes in it (like margin-bottom:5px; -- This will overrider margin-bottom:20px; )

The first is a list, the second is a tuple. Lists are mutable, tuples are not.

Take a look at the Data Structures section of the tutorial, and the Sequence Types section of the documentation.

There is definitly a problem with the destination folder path.

Your above error message says, it wants to put the contents to a file in the directory /files/grantapps/, which would be beyond your vhost, but somewhere in the system (see the leading absolute slash )

You should double check:

• Is the directory /home/username/public_html/files/grantapps/ really present.
• Contains your loop and your file_put_contents-Statement the absolute path /home/username/public_html/files/grantapps/

This should do it:

elif var == 80 or var == 443 or 1024 <= var <= 65535:

The non-greedy ? works perfectly fine. It's just that you need to select dot matches all option in the regex engines (regexpal, the engine you used, also has this option) you are testing with. This is because, regex engines generally don't match line breaks when you use .. You need to tell them explicitly that you want to match line-breaks too with .

For example,

<img\s.*?>

works fine!
