from learnyounode:

var http = require('http')
var bl = require('bl')

http.get(process.argv[2], function (response) {
    response.pipe(bl(function (err, data) {
        if (err)
            return console.error(err)
        data = data.toString()
        console.log(data)
    }))
})

For cross-language projects, I found out that strings containing RfC 3339 dates are the best way to go. An RfC 3339 date looks like this:

  1985-04-12T23:20:50.52Z

I think most of the format is obvious. The only somewhat unusual thing may be the "Z" at the end. It stands for GMT/UTC. You could also add a timezone offset like +02:00 for CEST (Germany in summer). I personally prefer to keep everything in UTC until it is displayed.

For displaying, comparisons and storage you can leave it in string format across all languages. If you need the date for calculations easy to convert it back to a native date object in most language.

So generate the JSON like this:

  json.dump(datetime.now().strftime('%Y-%m-%dT%H:%M:%SZ'))

Unfortunately, Javascript's Date constructor doesn't accept RfC 3339 strings but there are many parsers available on the Internet.

huTools.hujson tries to handle the most common encoding issues you might come across in Python code including date/datetime objects while handling timezones correctly.

All it needs is the installation of libpython [3 or 2] dev files installation.

The real problem is that you are using dynamic return type in the FacebookClient Get method. And although you use a method for serializing, the JSON converter cannot deserialize this Object after that.

Use insted of:

dynamic result = client.Get("fql", new { q = "select target_id,target_type from connection where source_id = me()"}); 
string jsonstring = JsonConvert.SerializeObject(result);

something like that:

string result = client.Get("fql", new { q = "select target_id,target_type from connection where source_id = me()"}).ToString();

Then you can use DeserializeObject method:

var datalist = JsonConvert.DeserializeObject<List<RootObject>>(result);

Hope this helps.

I realize I am a little late here, (5 years or so), but I think there is a better answer than the accepted one as follows:

$("#addComment").click(function() {
    if(typeof TinyMCE === "undefined") {
        $.ajax({
            url: "tinymce.js",
            dataType: "script",
            cache: true,
            success: function() {
                TinyMCE.init();
            }
        });
    }
});

The getScript() function actually prevents browser caching. If you run a trace you will see the script is loaded with a URL that includes a timestamp parameter:

http://www.yoursite.com/js/tinymce.js?_=1399055841840

If a user clicks the #addComment link multiple times, tinymce.js will be re-loaded from a differently timestampped URL. This defeats the purpose of browser caching.

===

Alternatively, in the getScript() documentation there is a some sample code that demonstrates how to enable caching by creating a custom cachedScript() function as follows:

jQuery.cachedScript = function( url, options ) {

    // Allow user to set any option except for dataType, cache, and url
    options = $.extend( options || {}, {
        dataType: "script",
        cache: true,
        url: url
    });

    // Use $.ajax() since it is more flexible than $.getScript
    // Return the jqXHR object so we can chain callbacks
    return jQuery.ajax( options );
};

// Usage
$.cachedScript( "ajax/test.js" ).done(function( script, textStatus ) {
    console.log( textStatus );
});

===

Or, if you want to disable caching globally, you can do so using ajaxSetup() as follows:

$.ajaxSetup({
    cache: true
});

Here is solution for Hibernate 4.3.7.Final.

pacakge-info.java contains

    }

    @Override

This solution mostly relies on TimestampType implementation with adding additional behaviour through anonymous class of type JdbcTimestampTypeDescriptor.

Another option would be to use the package ggplot2.

ggplot(mydata, aes(x = V3)) + geom_histogram() + scale_x_log10()

What I did:

1. Deleted that particular library's folder
2. composer update --prefer-source vendor/library-name

It fetches the library again along with it's git repo

A simple rule for us to remember what to use in which case:

• [S]ingle quotes are for [S]trings ; [D]ouble quotes are for [D]atabase identifiers;

In MySQL and MariaDB, the ` (backtick) symbol is the same as the " symbol. You can use " when your SQL_MODE has ANSI_QUOTES enabled.

Take a look at Serialization, a technique to "convert" an entire object to a byte stream. You may send it to the network or write it into a file and then restore it back to an object later.

Just running through a Visual Studio Code tutorial and came across a similiar issue.

Replace #include "stdafx.h" with #include "pch.h" which is the updated name for the precompiled headers.

This happens because VS doesn't know the schema of this file. Note that this file is more of an implementation detail, and not something you normally need to open directly. Instead, you can use the NuGet dialog to manage the packages installed in a project.

this happened to me when I imported an Android Studio App into eclipse.

I figured out the andoridmanifest.xml file needs to be slightly modified when importing from android studio project. I created a new test project, and copied over the headings to make it match. voila, issue solved.

use the pow function (it takes floats/doubles though).

man pow:

   #include <math.h>

   double pow(double x, double y);
   float powf(float x, float y);
   long double powl(long double x, long double y);

EDIT: For the special case of positive integer powers of 2, you can use bit shifting: (1 << x) will equal 2 to the power x. There are some potential gotchas with this, but generally, it would be correct.

As mentioned Agile is a set of principles about how a methodology should be implemented to achieve the benefits of embracing change, close co-operation etc. These principles address some of the project management issues found in studies such as the Chaos Report by the Standish group.

Agile methodologies are created by the development and supporting teams to meet the principles. The methodology is made to fit the business and changed as appropriate.

SCRUM is a fixed set of processes to implement an incremental development methodology. Since the processes are fixed and not catered to the teams it cannot really be considered agile in the original sense of focus on individuals rather than processes.

$("a.save, #country") 

will select both "a.save" class and "country" id.

The Readline API has changed quite a bit since 12'. The doc's show a useful example to capture user input from a standard stream :

const readline = require('readline');

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout
});

rl.question('What do you think of Node.js? ', (answer) => {
  console.log('Thank you for your valuable feedback:', answer);
  rl.close();
});

You can use the following command:

svn status -q

According to svnbook:

With --quiet (-q), it prints only summary information about locally modified items.

WARNING: The output of this command only shows your modification. So I suggest to do a svn up to get latest version of the file and then use svn status -q to get the files you have modified.

Instead of images i choose background option:

HTML:

  <div class="class1">
   <p>Some paragraph, Some paragraph, Some paragraph, Some paragraph, Some paragraph, 
   </p>
  </div>    
  <div class="class2">
   <p>Some paragraph, Some paragraph, Some paragraph, Some paragraph, Some paragraph, 
   </p>
  </div>
  <div class="class3">
   <p>Some paragraph, Some paragraph, Some paragraph, Some paragraph, Some paragraph, 
   </p>
  </div>        

CSS:

  .class1 {

    background: url("Some.png") no-repeat top center;
    text-align: center;

   }

  .class2 {

    background: url("Some2.png") no-repeat top center;
    text-align: center;

   }

  .class3 {

    background: url("Some3.png") no-repeat top center;
    text-align: center;

   }

You can create a RegExp object to make it a bit more readable

str.replace(new RegExp('/'), 'foobar');

If you want to replace all of them add the "g" flag

str.replace(new RegExp('/', 'g'), 'foobar');

This is now supported in Chrome by the "Pause on all exceptions" button.

To enable it:

• Go to the "Sources" tab in Chrome Developer Tools
• Click the "Pause" button at the bottom of the window to switch to "Pause on all exceptions mode".

Note that this button has multiple states. Keep clicking the button to switch between

• "Pause on all exceptions" - the button is colored light blue
• "Pause on uncaught exceptions", the button is colored purple.
• "Dont pause on exceptions" - the button is colored gray

This applies to "IntelliJ IDEA-2019.2.4" on Mac.

1. Navigate to "IntelliJ IDEA->Preferences->Editor->Code Style->Kotlin".
2. The "Packages to use Import with '' section on the screen will list "import java.util."

3. Click anywhere in that box and clear that entry.
4. Hit Apply and OK.

I experienced similar issues with Python 3.7 (3.7.0b4). This was due to some changes regarding some encoding assumptions (Python 3.6 >> Python 3.7)

As a result lots of package installations (e.g. via pip) failed.

Ok, this is pretty weird. I have a couple of projects: one is a UI project (an ASP.NET MVC project) and the others are projects for stuff like repositories. The repositories project had a reference to EF, but the UI project didn't (because it didn't need one, it just needed to reference the other projects). After I installed EF for the UI project as well, everything started working. This is why, it added this piece of code to my Web.config:

<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
  <providers>
    <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
  </providers>
</entityFramework>

I took a more compact approach to split an input resulting from a text area into a list of string . You can use this if suits your purpose.

the problem is you cannot split by \r\n so i removed the \n beforehand and split only by \r

var serials = model.List.Replace("\n","").Split('\r').ToList<string>();

I like this approach because you can do it in just one line.

Couldn't you just do this?

var things = [
    { id: 1, color: 'yellow' },
    { id: 2, color: 'blue' },
    { id: 3, color: 'red' }
];
$.post('@Url.Action("PassThings")', { things: things },
   function () {
        $('#result').html('"PassThings()" successfully called.');
   });

...and mark your action with

[HttpPost]
public void PassThings(IEnumerable<Thing> things)
{
    // do stuff with things here...
}

How To: Eclipse Maven install build jar with dependencies

i found out that this is not workable solution because the class loader doesn't load jars from within jars, so i think that i will unpack the dependencies inside the jar.

You are probably missing the viewport meta tag in the html head:

 <meta name="viewport" content="width=device-width, initial-scale=1">

Without it the device assumes and sets the viewport to full size.

This the simplest way to assign an async arrow function expression to a named variable:

const foo = async () => {
  // do something
}

_{(Note that this is not strictly equivalent to async function foo() { }. Besides the differences between the function keyword and an arrow expression, the function in this answer is not "hoisted to the top".)}

Thus, to summarise the existing discussion, adding

cex.lab=1.5, cex.axis=1.5, cex.main=1.5, cex.sub=1.5

to your plot, where 1.5 could be 2, 3, etc. and a value of 1 is the default will increase the font size.

x <- rnorm(100)

cex doesn't change things

hist(x, xlim=range(x),
     xlab= "Variable Lable", ylab="density", main="Title of plot", prob=TRUE)

hist(x, xlim=range(x),
     xlab= "Variable Lable", ylab="density", main="Title of plot", prob=TRUE, 
     cex=1.5)

Add cex.lab=1.5, cex.axis=1.5, cex.main=1.5, cex.sub=1.5

hist(x, xlim=range(x),
     xlab= "Variable Lable", ylab="density", main="Title of plot", prob=TRUE, 
     cex.lab=1.5, cex.axis=1.5, cex.main=1.5, cex.sub=1.5)

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

You can use TimeAgo extension as below:

public static string TimeAgo(this DateTime dateTime)
{
    string result = string.Empty;
    var timeSpan = DateTime.Now.Subtract(dateTime);
 
    if (timeSpan <= TimeSpan.FromSeconds(60))
    {
        result = string.Format("{0} seconds ago", timeSpan.Seconds);
    }
    else if (timeSpan <= TimeSpan.FromMinutes(60))
    {
        result = timeSpan.Minutes > 1 ? 
            String.Format("about {0} minutes ago", timeSpan.Minutes) :
            "about a minute ago";
    }
    else if (timeSpan <= TimeSpan.FromHours(24))
    {
        result = timeSpan.Hours > 1 ? 
            String.Format("about {0} hours ago", timeSpan.Hours) : 
            "about an hour ago";
    }
    else if (timeSpan <= TimeSpan.FromDays(30))
    {
        result = timeSpan.Days > 1 ? 
            String.Format("about {0} days ago", timeSpan.Days) : 
            "yesterday";
    }
    else if (timeSpan <= TimeSpan.FromDays(365))
    {
        result = timeSpan.Days > 30 ? 
            String.Format("about {0} months ago", timeSpan.Days / 30) : 
            "about a month ago";
    }
    else
    {
        result = timeSpan.Days > 365 ? 
            String.Format("about {0} years ago", timeSpan.Days / 365) : 
            "about a year ago";
    }
 
    return result;
}

Or use jQuery plugin with Razor extension from Timeago.

A quick note: Assume.assumeTrue(condition) ignores rest of the steps but passes the test. To fail the test, use org.junit.Assert.fail() inside the conditional statement. Works same like Assume.assumeTrue() but fails the test.

I realize this is an old post but as I just ran into the same issue and had trouble finding the answer I thought I'd add a bit.

So @hammar's answer is correct. Using push.default simple is, in a way, like configuring tracking on your branches so you don't need to specify remotes and branches when pushing and pulling. The matching option will push all branches to their corresponding counterparts on the default remote (which is the first one that was set up unless you've configured your repo otherwise).

One thing I hope others find useful in the future is that I was running Git 1.8 on OS X Mountain Lion and never saw this error. Upgrading to Mavericks is what suddenly made it show up (running git --version will show git version 1.8.3.4 (Apple Git-47) which I'd never seen until the update to the OS.

So your endpoint address defined in your first example is incomplete. You must also define endpoint identity as shown in client configuration. In code you can try this:

EndpointIdentity spn = EndpointIdentity.CreateSpnIdentity("host/mikev-ws");
var address = new EndpointAddress("http://id.web/Services/EchoService.svc", spn);   
var client = new EchoServiceClient(address); 
litResponse.Text = client.SendEcho("Hello World"); 
client.Close();

Actual working final version by valamas

EndpointIdentity spn = EndpointIdentity.CreateSpnIdentity("host/mikev-ws");
Uri uri = new Uri("http://id.web/Services/EchoService.svc");
var address = new EndpointAddress(uri, spn);
var client = new EchoServiceClient("WSHttpBinding_IEchoService", address);
client.SendEcho("Hello World");
client.Close(); 

You don't need case in the where statement, just use parentheses and or:

Select * From Times
WHERE StartDate <= @Date AND EndDate >= @Date
AND (
    (@day = 'Monday' AND Monday = 1)
    OR (@day = 'Tuesday' AND Tuesday = 1)
    OR Wednesday = 1
)

Additionally, your syntax is wrong for a case. It doesn't append things to the string--it returns a single value. You'd want something like this, if you were actually going to use a case statement (which you shouldn't):

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date)
AND 1 = CASE WHEN @day = 'Monday' THEN Monday
             WHEN @day = 'Tuesday' THEN Tuesday
             ELSE Wednesday
        END 

And just for an extra umph, you can use the between operator for your date:

where @Date between StartDate and EndDate

Making your final query:

select
    * 
from 
    Times
where
    @Date between StartDate and EndDate
    and (
        (@day = 'Monday' and Monday = 1)
        or (@day = 'Tuesday' and Tuesday = 1)
        or Wednesday = 1
    )

Use a value filter. Click the dropdown arrow next to your Row Labels and you'll see a choice between Sort A to Z, Label Filters, and Value Filters. Selecting a Greater Than value filter will let you choose which column to use to filter out rows, even if that column has no dropdown arrow itself.

As far as I can tell, this happens when the project dependencies gets messed up for whatever reason (whilst all the inter-project references are still intact). For many cases, it is NOT a code issue. And for those who have more than a few projects, going through them one at a time is NOT acceptable.

It's easy to reset project dependencies -

1. Select all projects and right click unload
2. Select all projects and right click reload
3. Rebuild solution

For those who have an issue in their code or some other issue that's causing this problem you'll obviously have to solve that issue first.

For me, using OS X Catalina: Changing from AllowOverride None to AllowOverride All is the one that works.

httpd.conf is located on /etc/apache2/httpd.conf.

I have never seen it done that way in JavaScript. If you want a function with optional parameters that get assigned default values if the parameters are omitted, here's a way to do it:

 function(a, b) {
      if (typeof a == "undefined") {
        a = 10;
      }

      if (typeof b == "undefined") {
        a = 20;
      }

      alert("a: " + a + " b: " + b);
    }

The git interaction library part of StGit is actually pretty good. However, it isn't broken out as a separate package but if there is sufficient interest, I'm sure that can be fixed.

It has very nice abstractions for representing commits, trees etc, and for creating new commits and trees.

I had the same problem today, here's how I solved it so I could keep lexical_cast<>

typedef unsigned int    uint32;
typedef signed int      int32;

class uint32_from_hex   // For use with boost::lexical_cast
{
    uint32 value;
public:
    operator uint32() const { return value; }
    friend std::istream& operator>>( std::istream& in, uint32_from_hex& outValue )
    {
        in >> std::hex >> outValue.value;
    }
};

class int32_from_hex   // For use with boost::lexical_cast
{
    uint32 value;
public:
    operator int32() const { return static_cast<int32>( value ); }
    friend std::istream& operator>>( std::istream& in, int32_from_hex& outValue )
    {
        in >> std::hex >> outvalue.value;
    }
};

uint32 material0 = lexical_cast<uint32_from_hex>( "0x4ad" );
uint32 material1 = lexical_cast<uint32_from_hex>( "4ad" );
uint32 material2 = lexical_cast<uint32>( "1197" );

int32 materialX = lexical_cast<int32_from_hex>( "0xfffefffe" );
int32 materialY = lexical_cast<int32_from_hex>( "fffefffe" );
// etc...

Using https://stackoverflow.com/a/1804095 and JeffFisher30's answer above (https://stackoverflow.com/a/14572370/6147425) and my own need to have fractional days, I wrote this:

After installing any version of Xcode targeting Intel-based Macs, you should be able to write assembly code. Xcode is a suite of tools, only one of which is the IDE, so you don't have to use it if you don't want to. (That said, if there are specific things you find clunky, please file a bug at Apple's bug reporter - every bug goes to engineering.) Furthermore, installing Xcode will install both the Netwide Assembler (NASM) and the GNU Assembler (GAS); that will let you use whatever assembly syntax you're most comfortable with.

You'll also want to take a look at the Compiler & Debugging Guides, because those document the calling conventions used for the various architectures that Mac OS X runs on, as well as how the binary format and the loader work. The IA-32 (x86-32) calling conventions in particular may be slightly different from what you're used to.

Another thing to keep in mind is that the system call interface on Mac OS X is different from what you might be used to on DOS/Windows, Linux, or the other BSD flavors. System calls aren't considered a stable API on Mac OS X; instead, you always go through libSystem. That will ensure you're writing code that's portable from one release of the OS to the next.

Finally, keep in mind that Mac OS X runs across a pretty wide array of hardware - everything from the 32-bit Core Single through the high-end quad-core Xeon. By coding in assembly you might not be optimizing as much as you think; what's optimal on one machine may be pessimal on another. Apple regularly measures its compilers and tunes their output with the "-Os" optimization flag to be decent across its line, and there are extensive vector/matrix-processing libraries that you can use to get high performance with hand-tuned CPU-specific implementations.

Going to assembly for fun is great. Going to assembly for speed is not for the faint of heart these days.

less will look in its environment to see if there is a variable named LESS

You can set LESS in one of your ~/.profile (.bash_rc, etc, etc) and then anytime you run less from the comand line, it will find the LESS.

Try adding this

export LESS="-CQaix4"

This is the setup I use, there are some behaviors embedded in that may confuse you, so you can find out about what all of these mean from the help function in less, just tap the 'h' key and nose around, or run less --help.

Edit:

I looked at the help, and noticed there is also an -r option

-r  -R  ....  --raw-control-chars  --RAW-CONTROL-CHARS
                Output "raw" control characters.

I agree that cat may be the most exact match to your stated needs.

cat -vet file | less

Will add '$' at end of each line and convert tab char to visual '^I'.

cat --help
   (edited)
    -e                       equivalent to -vE
    -E, --show-ends          display $ at end of each line
    -t                       equivalent to -vT
    -T, --show-tabs          display TAB characters as ^I
    -v, --show-nonprinting   use ^ and M- notation, except for LFD and TAB

I hope this helps.

You had thead in your selector, but there is no thead in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr class to the th, not vice-versa (although your comment seems to contradict what you wrote up above).

$('tr th').each(function(index){     if($('tr td').eq(index).attr('class') != ''){         // get the class of the td         var tdClass = $('tr td').eq(index).attr('class');         // add it to this th         $(this).addClass(tdClass );     } });

1. Install Xcode and Xcode Command Line Tools as mentioned.
2. Use Pillow instead, as PIL is basically dead. Pillow is a maintained fork of PIL.

https://pypi.org/project/Pillow/

pip install Pillow

If you have both Pythons installed and want to install this for Python3:

python3 -m pip install Pillow

In Bash shell:

#!/bin/sh

COUNTER=1

while [ $COUNTER -lt 254 ]
do
   ping 192.168.1.$COUNTER -c 1
   COUNTER=$(( $COUNTER + 1 ))
done

You are most likely pushing a string 'NULL' to the table, rather then an actual NULL, but other things may be going on as well, an illustration:

mysql> CREATE TABLE date_test (pdd DATE NOT NULL);
Query OK, 0 rows affected (0.11 sec)

mysql> INSERT INTO date_test VALUES (NULL);
ERROR 1048 (23000): Column 'pdd' cannot be null
mysql> INSERT INTO date_test VALUES ('NULL');
Query OK, 1 row affected, 1 warning (0.05 sec)

mysql> show warnings;

I assume bash is running on a vt100-compatible terminal in which the user did not explicitly turn off the support for formatting.

First, turn on support for special characters in echo, using -e option. Later, use ansi escape sequence ESC[1m, like:

echo -e "\033[1mSome Text"

More on ansi escape sequences for example here: ascii-table.com/ansi-escape-sequences-vt-100.php

Reset single select field to default option.

<select id="name">
    <option>select something</option>
    <option value="1" >something 1</option>
    <option value="2" selected="selected" >Default option</option>
</select>
<script>
    $('name').val( $('name').find("option[selected]").val() );
</script>

Or if you want to reset all form fields to the default option:

<script>
    $('select').each( function() {
        $(this).val( $(this).find("option[selected]").val() );
    });
</script>

Have you set the Table Cell identifier to "Cell" in your storyboard?

Or have you set the class for the UITableViewController to your class in that scene?

If you know about Environment variables and the system variable called path, consider that any version of any binary which comes sooner, will be used as default.

Look at the image below, I have 3 different python versions but python 3.8 will be used as default since it came sooner than the other two. (In case of mentioned image, sooner means higher!)

In the initialization chunk I define a function

pagebreak <- function() {
  if(knitr::is_latex_output())
    return("\\newpage")
  else
    return('<div style="page-break-before: always;" />')
}

In the markdown part where I want to insert a page break, I type

`r pagebreak()`

the better approach for sending data from activity class to fragment is passing via setter methods. Like

FragmentClass fragmentClass = new FragmentClass();
fragmentClass.setMyList(mylist);
fragmentClass.setMyString(myString);
fragmentClass.setMyMap(myMap);

and get these data from the class easily.

I'd highly recommend jQuery. It then becomes as simple as:

$('#mydiv').addClass('newclass');

You don't have to worry about removing the old class then as addClass() will only append to it. You also have removeClass();

The other advantage over the getElementById() method is you can apply it to multiple elements at the same time with a single line of code.

$('div').addClass('newclass');
$('.oldclass').addClass('newclass');

The first example will add the class to all DIV elements on the page. The second example will add the new class to all elements that currently have the old class.

I need to do this and have the <dt> content vertically centered, relative to the <dd> content. I used display: inline-block, together with vertical-align: middle

See full example on Codepen here

.dl-horizontal {
  font-size: 0;
  text-align: center;

  dt, dd {
    font-size: 16px;
    display: inline-block;
    vertical-align: middle;
    width: calc(50% - 10px);
  }

  dt {
    text-align: right;
    padding-right: 10px;
  }

  dd {
    font-size: 18px;
    text-align: left;
    padding-left: 10px;
  } 
}

You don't need to download any new software. You can use Octave Online to open .m files.

I have combined some answers from the above thread and come up with the solution below. Although it is simple it can be used as a building block for making more complex key updates from a dictionary.

test_dict = {'a': 1, 'b': 2, 'c': 3}
print(test_dict)
# {'a': 1, 'b': 2, 'c': 3}
prefix = 'up'
def dict_key_update(json_file):    
    new_keys = []
    old_keys = []
    for i,(key,value) in enumerate(json_file.items()):
        old_keys.append(key)
        new_keys.append(str(prefix) + key) # i have updated by adding a prefix to the 
        # key
    for old_key, new_key in zip(old_keys,new_keys):
        print('old {}, new {}'.format(old_key, new_key))
        if new_key!=old_key:  
           json_file[new_key] = json_file.pop(old_key)
     return json_file

test_dict = dict_key_update(test_dict)
print(test_dict)
# {'upa': 1, 'upb': 2, 'upc': 3}

$Date3 = date('y-m-d');
$Date2 = date('y-m-d', strtotime("-7 days"));

SELECT * FROM disaster WHERE date BETWEEN '".$Date2."' AND  '".$Date3."'

Another DISTINCT answer, but with multiple values:

SELECT DISTINCT `field1`, `field2`, `field3` FROM `some_table`  WHERE `some_field` > 5000 ORDER BY `some_field`

Use the SqlDataAdapter, this would simplify everything.

//Your code to this point
DataTable dt = new DataTable();

using(var cmd = new SqlCommand("usp_GetABCD", sqlcon))
{
  using(var da = new SqlDataAdapter(cmd))
  {
      da.Fill(dt):
  }
}

and your DataTable will have the information you are looking for, so long as your stored proceedure returns a data set (cursor).

Oracle recommends to add the @Path annotation to all types to be injected when combining JAX-RS with CDI: http://docs.oracle.com/javaee/7/tutorial/jaxrs-advanced004.htm Though this is far from perfect (e.g. you will get warning from Jersey on startup), I decided to take this route, which saves me from maintaining all supported types within a binder.

Example:

@Singleton
@Path("singleton-configuration-service")
public class ConfigurationService {
  .. 
}

@Path("my-path")
class MyProvider {
  @Inject ConfigurationService _configuration;

  @GET
  public Object get() {..}
}

You can do it. this is a easy way.

If you want to use the catch() of the Observable you need to use Observable.throw() method before delegating the error response to a method

import { Injectable } from '@angular/core';_x000D_
import { Headers, Http, ResponseOptions} from '@angular/http';_x000D_
import { AuthHttp } from 'angular2-jwt';_x000D_
_x000D_
import { MEAT_API } from '../app.api';_x000D_
_x000D_
import { Observable } from 'rxjs/Observable';_x000D_
import 'rxjs/add/operator/map';_x000D_
import 'rxjs/add/operator/catch';_x000D_
_x000D_
@Injectable()_x000D_
export class CompareNfeService {_x000D_
_x000D_
_x000D_
  constructor(private http: AuthHttp) {}_x000D_
_x000D_
  envirArquivos(order): Observable < any > {_x000D_
    const headers = new Headers();_x000D_
    return this.http.post(`${MEAT_API}compare/arquivo`, order,_x000D_
        new ResponseOptions({_x000D_
          headers: headers_x000D_
        }))_x000D_
      .map(response => response.json())_x000D_
      .catch((e: any) => Observable.throw(this.errorHandler(e)));_x000D_
  }_x000D_
_x000D_
  errorHandler(error: any): void {_x000D_
    console.log(error)_x000D_

}

Using Observable.throw() worked for me

SharedPreferences are stored in an xml file in the app data folder, i.e.

/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PREFS_NAME.xml

or the default preferences at:

/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PACKAGE_NAME_preferences.xml

SharedPreferences added during runtime are not stored in the Eclipse project.

Note: Accessing /data/data/<package_name> requires superuser privileges

Set the html and body tags height to 100% and remove the margin around the body:

html, body {
    height: 100%;
    margin: 0px; /* Remove the margin around the body */
}

Now set the position of your div to fixed:

#dimScreen
{
    width: 100%;
    height: 100%;
    background:rgba(255,255,255,0.5);

    position: fixed;
    top: 0px;
    left: 0px;

    z-index: 1000; /* Now the div will be on top */
}

Demo: http://jsfiddle.net/F3LHW/

Cause

From the MDN documentation:

[The margin property] applies to all elements except elements with table display types other than table-caption, table and inline-table

In other words, the margin property is not applicable to display:table-cell elements.

Solution

Consider using the border-spacing property instead.

Note it should be applied to a parent element with a display:table layout and border-collapse:separate.

For example:

HTML

<div class="table">
    <div class="row">
        <div class="cell">123</div>
        <div class="cell">456</div>
        <div class="cell">879</div>
    </div>
</div>

CSS

.table {display:table;border-collapse:separate;border-spacing:5px;}
.row {display:table-row;}
.cell {display:table-cell;padding:5px;border:1px solid black;}

See jsFiddle demo

Different margin horizontally and vertically

As mentioned by Diego Quirós, the border-spacing property also accepts two values to set a different margin for the horizontal and vertical axes.

For example

.table {/*...*/border-spacing:3px 5px;} /* 3px horizontally, 5px vertically */

My approach was to make a virtual attribute instead of adding database columns.

class Choice
  belongs_to :user
  belongs_to :answer

  # ------- Helpers -------
  def question
    answer.question
  end

  # extra sugar
  def question_id
    answer.question_id
  end
end

This approach is pretty simple, but comes with tradeoffs. It requires Rails to load answer from the db, and then question. This can be optimized later by eager loading the associations you need (i.e. c = Choice.first(include: {answer: :question})), however, if this optimization is necessary, then stephencelis' answer is probably a better performance decision.

There's a time and place for certain choices, and I think this choice is better when prototyping. I wouldn't use it for production code unless I knew it was for an infrequent use case.

I have used Excel/PowerPivot to create the postgreSQL insert statement. Seems like overkill, except when you need to do it over and over again. Once the data is in the PowerPivot window, I add successive columns with concatenate statements to 'build' the insert statement. I create a flattened pivot table with that last and final column. Copy and paste the resulting insert statement into my EXISTING postgreSQL table with pgAdmin.

Example two column table (my table has 30 columns from which I import successive contents over and over with the same Excel/PowerPivot.)

Column1 {a,b,...} Column2 {1,2,...}

In PowerPivot I add calculated columns with the following commands:

Calculated Column 1 has "insert into table_name values ('"

Calculated Column 2 has CONCATENATE([Calculated Column 1],CONCATENATE([Column1],"','"))

...until you get to the last column and you need to terminate the insert statement:

Calculated Column 3 has CONCATENATE([Calculated Column 2],CONCATENATE([Column2],"');"

Then in PowerPivot I add a flattened pivot table and have all of the insert statement that I just copy and paste to pgAgent.

Resulting insert statements:

insert into table_name values ('a','1');

insert into table_name values ('b','2');

insert into table_name values ('c','3');

NOTE: If you are familiar with the power pivot CONCATENATE statement, you know that it can only handle 2 arguments (nuts). Would be nice if it allowed more.

you can try this:"Filename.txt" file will be created automatically in the bin->debug folder everytime you run this code or you can specify path of the file like: @"C:/...". you can check ëxistance of "Hello" by going to the bin -->debug folder

P.S dont forget to add Console.Readline() after this code snippet else console will not appear.

TextWriter tw = new StreamWriter("filename.txt");
        String text = "Hello";
        tw.WriteLine(text);
        tw.Close();

        TextReader tr = new StreamReader("filename.txt");
        Console.WriteLine(tr.ReadLine());
        tr.Close();

You can use pandas.Dataframe.isin.

pandas.Dateframe.isin will return boolean values depending on whether each element is inside the list a or not. You then invert this with the ~ to convert True to False and vice versa.

import pandas as pd

a = ['2015-01-01' , '2015-02-01']

df = pd.DataFrame(data={'date':['2015-01-01' , '2015-02-01', '2015-03-01' , '2015-04-01', '2015-05-01' , '2015-06-01']})

print(df)
#         date
#0  2015-01-01
#1  2015-02-01
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

df = df[~df['date'].isin(a)]

print(df)
#         date
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

This may be a late reply. But it may help others. It is very simple in MY SQL Workbench ( I am using Workbench version 6.3 and My SQL Version 5.1 Community edition): Right click on the table for which you want the create script, select 'Copy to Clipboard --> Create Statement' option. Simply paste in any text editor you want to get the create script.

You can probably start a Service here if you want your Application to run in Background. This is what Service in Android are used for - running in background and doing longtime operations.

UDPATE

You can use START_STICKY to make your Service running continuously.

@Override

    handleCommand(intent);
    // We want this service to continue running until it is explicitly
    // stopped, so return sticky.
    return START_STICKY;
}

I created a procedure to search text in procedures/functions, tables, views, or jobs. The first parameter @search is the search criterion, @target the search target, i.e., procedures, tables, etc. If not specified, search all. @db is to specify the database to search, default to your current database.

Update: If you renamed a procedure, it only updates sysobjects but not syscomments, which keeps the old name and therefore that procedure will not be included in the search result unless you drop and recreate the procedure.

I was having the same issue and this works excellently.

Private Sub DataGridView17_CellFormatting(sender As Object, e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView17.CellFormatting  
  'Display complete contents in tooltip even though column display cuts off part of it.   
  DataGridView17.Rows(e.RowIndex).Cells(e.ColumnIndex).ToolTipText = DataGridView17.Rows(e.RowIndex).Cells(e.ColumnIndex).Value 
End Sub

I was also having the trouble to route to a different view using navlink.

My implementation was as follows and works perfectly;

<NavLink tag='li'>
  <div
    onClick={() =>
      this.props.history.push('/admin/my- settings')
    }
  >
    <DropdownItem className='nav-item'>
      Settings
    </DropdownItem>
  </div>
</NavLink>

Wrap it with a div, assign the onClick handler to the div. Use the history object to push a new view.

The threadunsafety of SimpleDateFormat should not be an issue if you just create it inside the very same method block as you use it. In other words, you are not assigning it as static or instance variable of a class and reusing it in one or more methods which can be invoked by multiple threads. Only this way the threadunsafety of SimpleDateFormat will be exposed. You can however safely reuse the same SimpleDateFormat instance within the very same method block as it would be accessed by the current thread only.

Also, the java.sql.Timestamp class which you're using there should not be abused as it's specific to the JDBC API in order to be able to store or retrieve a TIMESTAMP/DATETIME column type in a SQL database and convert it from/to java.util.Date.

So, this should do:

Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy h:mm:ss a");
String formattedDate = sdf.format(date);
System.out.println(formattedDate); // 12/01/2011 4:48:16 PM

Instead of replace we can force culture like

var x = decimal.Parse("18,285", new NumberFormatInfo() { NumberDecimalSeparator = "," });

it will give output 18.285

You could always use something like mktime to create a known time (midnight, last night) and use difftime to get a double-precision time difference between the two. For a platform-independant solution, unless you go digging into the details of your libraries, you're not going to do much better than that. According to the C spec, the definition of time_t is implementation-defined (meaning that each implementation of the library can define it however they like, as long as library functions with use it behave according to the spec.)

That being said, the size of time_t on my linux machine is 8 bytes, which suggests a long int or a double. So I did:

int main()
{
    for(;;)
    {
        printf ("%ld\n", time(NULL));
        printf ("%f\n", time(NULL));
        sleep(1);
    }
    return 0;
}

The time given by the %ld increased by one each step and the float printed 0.000 each time. If you're hell-bent on using printf to display time_ts, your best bet is to try your own such experiment and see how it work out on your platform and with your compiler.

OrderedDictionary dict = dc.TableName.ToDictionary(d => d.key, d => d.value);

In order to retrieve the values use namespace

   using System.Collections;

ICollection keyCollections = dict.Keys;
ICOllection valueCollections = dict.Values;

String[] myKeys = new String[dict.Count];
String[] myValues = new String[dict.Count];

keyCollections.CopyTo(myKeys,0);
valueCollections.CopyTo(myValues,0);

for(int i=0; i<dict.Count; i++)
{
Console.WriteLine("Key: " + myKeys[i] + "Value: " + myValues[i]);
}
Console.ReadKey();

Based on the comments above, here is a simple test:

isunset() { [[ "${!1}" != 'x' ]] && [[ "${!1-x}" == 'x' ]] && echo 1; }
isset()   { [ -z "$(isunset "$1")" ] && echo 1; }

Example:

$ unset foo; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's unset
$ foo=     ; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's set
$ foo=bar  ; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's set

Suppose your hex string is something like

>>> hex_string = "deadbeef"

Convert it to a string (Python = 2.7):

>>> hex_data = hex_string.decode("hex")
>>> hex_data
"\xde\xad\xbe\xef"

or since Python 2.7 and Python 3.0:

>>> bytes.fromhex(hex_string)  # Python = 3
b'\xde\xad\xbe\xef'

>>> bytearray.fromhex(hex_string)
bytearray(b'\xde\xad\xbe\xef')

Note that bytes is an immutable version of bytearray.

This may be not the full answer to your question, however if you are looking for way to disable csrf protection you can do:

@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/web/admin/**").hasAnyRole(ADMIN.toString(), GUEST.toString())
                .anyRequest().permitAll()
                .and()
                .formLogin().loginPage("/web/login").permitAll()
                .and()
                .csrf().ignoringAntMatchers("/contact-email")
                .and()
                .logout().logoutUrl("/web/logout").logoutSuccessUrl("/web/").permitAll();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("admin").password("admin").roles(ADMIN.toString())
                .and()
                .withUser("guest").password("guest").roles(GUEST.toString());
    }

}

I have included full configuration but the key line is:

.csrf().ignoringAntMatchers("/contact-email")

My solution for BlueJ is to edit the New Class template "stdclass.tmpl" in Program Files (x86)\BlueJ\lib\english\templates\newclass and add this method:

public static <T> void p(T s)
{
    System.out.println(s);
}

Or this other version:

public static void p(Object s)
{
    System.out.println(s);
}

As for Eclipse I'm using the suggested shortcut syso + <Ctrl> + <Space> :)

SlickGrid has this functionality, see the tree demo.

If you want to build your own, here is an example (jsFiddle demo): Build your table with a data-depth attribute to indicate the depth of the item in the tree (the levelX CSS classes are just for styling indentation): 

<table id="mytable">
    <tr data-depth="0" class="collapse level0">
        <td><span class="toggle collapse"></span>Item 1</td>
        <td>123</td>
    </tr>
    <tr data-depth="1" class="collapse level1">
        <td><span class="toggle"></span>Item 2</td>
        <td>123</td>
    </tr>
</table>

Then when a toggle link is clicked, use Javascript to hide all <tr> elements until a <tr> of equal or less depth is found (excluding those already collapsed):

$(function() {
    $('#mytable').on('click', '.toggle', function () {
        //Gets all <tr>'s  of greater depth below element in the table
        var findChildren = function (tr) {
            var depth = tr.data('depth');
            return tr.nextUntil($('tr').filter(function () {
                return $(this).data('depth') <= depth;
            }));
        };

        var el = $(this);
        var tr = el.closest('tr'); //Get <tr> parent of toggle button
        var children = findChildren(tr);

        //Remove already collapsed nodes from children so that we don't
        //make them visible. 
        //(Confused? Remove this code and close Item 2, close Item 1 
        //then open Item 1 again, then you will understand)
        var subnodes = children.filter('.expand');
        subnodes.each(function () {
            var subnode = $(this);
            var subnodeChildren = findChildren(subnode);
            children = children.not(subnodeChildren);
        });

        //Change icon and hide/show children
        if (tr.hasClass('collapse')) {
            tr.removeClass('collapse').addClass('expand');
            children.hide();
        } else {
            tr.removeClass('expand').addClass('collapse');
            children.show();
        }
        return children;
    });
});

Wow! Mean this that you must learn a different programming language just to send two keys to the keyboard? There are simpler ways for you to achieve the same thing. :-)

The Batch file below is an example that start another program (cmd.exe in this case), send a command to it and then send an Up Arrow key, that cause to recover the last executed command. The Batch file is simple enough to be understand with no problems, so you may modify it to fit your needs.

@if (@CodeSection == @Batch) @then


@echo off

rem Use %SendKeys% to send keys to the keyboard buffer
set SendKeys=CScript //nologo //E:JScript "%~F0"

rem Start the other program in the same Window
start "" /B cmd

%SendKeys% "echo off{ENTER}"

set /P "=Wait and send a command: " < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "echo Hello, world!{ENTER}"

set /P "=Wait and send an Up Arrow key: [" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{UP}"

set /P "=] Wait and send an Enter key:" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{ENTER}"

%SendKeys% "exit{ENTER}"

goto :EOF


@end


// JScript section

var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.SendKeys(WScript.Arguments(0));

For a list of key names for SendKeys, see: http://msdn.microsoft.com/en-us/library/8c6yea83(v=vs.84).aspx

For example:

LEFT ARROW    {LEFT}
RIGHT ARROW   {RIGHT}

For a further explanation of this solution, see: GnuWin32 openssl s_client conn to WebSphere MQ server not closing at EOF, hangs

As of now (Jan 2017 / Angular > 2.0) you can use the following:

changeBackground(): any {
    return { 'background-color': this.color };
}

and

<div class="circle" [ngStyle]="changeBackground()">
    <!-- <content></content> --> <!-- content is now deprecated -->
    <ng-content><ng-content> <!-- Use ng-content instead -->
</div>

The shortest way is probably like this:

<div class="circle" [ngStyle]="{ 'background-color': color }">
    <!-- <content></content> --> <!-- content is now deprecated -->
    <ng-content><ng-content> <!-- Use ng-content instead -->
</div>

os.path.isdir() checks if the path exists and is a directory and returns TRUE for the case.

Similarly, os.path.isfile() checks if the path exists and is a file and returns TRUE for the case.

And, os.path.exists() checks if the path exists and doesn’t care if the path points to a file or a directory and returns TRUE in either of the cases.

I can recommend make pre-init of future index value, this is very usefull in a lot of case like multi work, some export e.t.c.

just create additional User_Seq table: with two fields: id Uniq index and SeqVal nvarchar(1)

and create next SP, and generated ID value from this SP and put to new User row!

CREATE procedure [dbo].[User_NextValue]
as
begin
    set NOCOUNT ON


    declare @existingId int = (select isnull(max(UserId)+1, 0)  from dbo.User)

    insert into User_Seq (SeqVal) values ('a')
    declare @NewSeqValue int = scope_identity()     

    if @existingId > @NewSeqValue 
    begin  

        set identity_insert User_Seq  on
        insert into User_Seq (SeqID) values (@existingId)     
        set @NewSeqValue = scope_identity()     
    end

    delete from User_Seq WITH (READPAST)

return @NewSeqValue

end

If you need a weak reference to the cell value:

object field = d.Rows[0][3]

or

object field = d.Rows[0].ItemArray[3]

Should do it

If you need a strongly typed reference (string in your case) you can use the DataRowExtensions.Field extension method:

string field = d.Rows[0].Field<string>(3);

(make sure System.Data is in listed in the namespaces in this case)

Indexes are 0 based so we first access the first row (0) and then the 4th column in this row (3)

Generally, I am using the following method:

>>> myStr = "Hi\n Stack Over \r flow!"
>>> charList = [u"\u005Cn",u"\u005Cr",u"\u005Ct"]
>>> import re
>>> for i in charList:
        myStr = re.sub(i, r"", myStr)

>>> myStr
'Hi Stack Over  flow'

Note: This is only for removing "\n", "\r" and "\t" only. It does not remove extra spaces.

margin and padding don't have min or max prefixes. Sometimes you can try to specify margin and padding in terms of percentage to make it variable with respect to screen size.

Further you can also use min-width, max-width, min-height and max-height for doing the similar things.

Hope it helps.

I'm not sure if this was your problem but for anyone that's trying to access his web application from his machine and having this problem:

Make sure you're connecting to 127.0.0.1 (a.k.a localhost) and not to your external IP address.

Your URL should be something like http://localhost:8181/ or http://127.0.0.1:8181 and not http://YourExternalIPaddress:8181/.

When you connect to your external IP address, you connect to you from the internet, as if you were a stranger (or a hacker).
However when you connect to your localhost, you connect locally as yourself and the block is obviously not needed (& avoided altogether).

Deleting a null pointer has no effect. It's not good coding style necessarily because it's not needed, but it's not bad either.

If you are searching for good coding practices consider using smart pointers instead so then you don't need to delete at all.

* * * * * myjob.sh >> /var/log/myjob.log 2>&1

will log all output from the cron job to /var/log/myjob.log

You might use mail to send emails. Most systems will send unhandled cron job output by email to root or the corresponding user.

I found a way to do it (dont know if it is the best but it works)

string oldFile = "oldFile.pdf";
string newFile = "newFile.pdf";

// open the reader
PdfReader reader = new PdfReader(oldFile);
Rectangle size = reader.GetPageSizeWithRotation(1);
Document document = new Document(size);

// open the writer
FileStream fs = new FileStream(newFile, FileMode.Create, FileAccess.Write);
PdfWriter writer = PdfWriter.GetInstance(document, fs);
document.Open();

// the pdf content
PdfContentByte cb = writer.DirectContent;

// select the font properties
BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252,BaseFont.NOT_EMBEDDED);
cb.SetColorFill(BaseColor.DARK_GRAY);
cb.SetFontAndSize(bf, 8);

// write the text in the pdf content
cb.BeginText();
string text = "Some random blablablabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(1, text, 520, 640, 0);
cb.EndText();
cb.BeginText();
text = "Other random blabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(2, text, 100, 200, 0);
cb.EndText();

// create the new page and add it to the pdf
PdfImportedPage page = writer.GetImportedPage(reader, 1);
cb.AddTemplate(page, 0, 0);

// close the streams and voilá the file should be changed :)
document.Close();
fs.Close();
writer.Close();
reader.Close();

I hope this can be usefull for someone =) (and post here any errors)

very basic:

<?php 
$username = 'user';
$password = 'password';
$server = 'localhost'; 
// Opens a connection to a MySQL server
$connection = mysql_connect ($server, $username, $password) or die('try again in some minutes, please');
//if you want to suppress the error message, substitute the connection line for:
//$connection = @mysql_connect($server, $username, $password) or die('try again in some minutes, please');
?>

result:

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'user'@'localhost' (using password: YES) in /home/user/public_html/zdel1.php on line 6 try again in some minutes, please

as per Wrikken's recommendation below, check out a complete error handler for more complex, efficient and elegant solutions: http://www.php.net/manual/en/function.set-error-handler.php

Correct, when you drag a view controller object onto your storyboard in order to create a new scene, it doesn't automatically make the new class for you, too.

Having added a new view controller scene to your storyboard, you then have to:

1. Create a UIViewController subclass. For example, go to your target's folder in the project navigator panel on the left and then control-click and choose "New File...". Choose a "Cocoa Touch Class":

   

   And then select a unique name for the new view controller subclass:

   

2. Specify this new subclass as the base class for the scene you just added to the storyboard.

   

3. Now hook up any IBOutlet and IBAction references for this new scene with the new view controller subclass.

Alternate solution can be:

baseKey hKeyLocalMachine = baseKey.HKEY_LOCAL_MACHINE;
uint value = (uint)hKeyLocalMachine;

Or just:

uint value = (uint)baseKey.HKEY_LOCAL_MACHINE;

1. Set up your routes to accept data

{
    path: 'some-route',
    loadChildren: 
      () => import(
        './some-component/some-component.module'
      ).then(
        m => m.SomeComponentModule
      ),
    data: {
      key: 'value',
      ...
    },
}

2. Navigate to route:

From HTML:

<a [routerLink]=['/some-component', { key: 'value', ... }> ... </a>

Or from Typescript:

import {Router} from '@angular/router';

...

 this.router.navigate(
    [
       '/some-component',
       {
          key: 'value',
          ...
       }
    ]
 );

3. Get data from route

import {ActivatedRoute} from '@angular/router';

...

this.value = this.route.snapshot.params['key'];

After breaking an entire day on the exact same issue , with no prior knowledge on SSL certificates, i downloaded the CERTivity Keystores Manager and imported my keystore to it, and got a clear-cut visualisation of the certificate chain.

Screenshot :

In your stylesheet:

div#content.myClass

Edit: These might help, too:

div#content.myClass.aSecondClass.aThirdClass /* Won't work in IE6, but valid */
div.firstClass.secondClass /* ditto */

and, per your example:

div#content.sectionA

Edit, 4 years later: Since this is super old and people keep finding it: don't use the tagNames in your selectors. #content.myClass is faster than div#content.myClass because the tagName adds a filtering step that you don't need. Use tagNames in selectors only where you must!

Assuming you have a properties file on your classpath that contains

api.orders.pingFrequency=4

I tried inside a @Controller

@Controller
public class MyController {     
    @Value("${api.orders.pingFrequency}")
    private Integer pingFrequency;
    ...
}

With my servlet context containing :

<context:property-placeholder location="classpath:myprops.properties" />

It worked perfectly.

So either your property is not an integer type, you don't have the property placeholder configured correctly, or you are using the wrong property key.

I tried running with an invalid property value, 4123;. The exception I got is

java.lang.NumberFormatException: For input string: "4123;"

which makes me think the value of your property is

api.orders.pingFrequency=(java.lang.Integer)${api.orders.pingFrequency}

When you return something from a then() callback, it's a bit magic. If you return a value, the next then() is called with that value. However, if you return something promise-like, the next then() waits on it, and is only called when that promise settles (succeeds/fails).

I don't like very much iterator's semantic, please consider this as an option. It's also safer as you publish less of your internal state

private Map<String, String> JSONtoMAP(String jsonString) {

    JSONObject json = new JSONObject(jsonString);
    Map<String, String> outMap = new HashMap<String, String>();

    for (String curKey : (Set<String>) json.keySet()) {
        outMap.put(curKey, json.getString(curKey));
    }

    return outMap;

}

How do you send the message?

The classes in the System.Net.Mail namespace (which is probably what you should use) has full support for authentication, either specified in Web.config, or using the SmtpClient.Credentials property.

I just think the whole example would be useful. This is the example for this problem.

In order to build a more-or-less reliable list of applications that appear in the "Programs and Feautres" in the Control Panel, you have to consider that not all applications were installed using MSI. WMI only provides the ones installed with MSI.

Here is a short summary of what I've found out:

MSI applications always have a Product Code (GUID) subkey under HKLM\...\Uninstall and/or under HKLM\...\Installer\UserData\S-1-5-18\Products. In addition, they may have a key that looks like HKLM\...\Uninstall\NotAGuid.

Non-MSI applications do not have a product code, and therefore have keys like HKLM\...\Uninstall\NotAGuid or HKCU\...\Uninstall\NotAGuid.

If you already added all libraries and it still doesn't work use:

<com.google.android.material.floatingactionbutton.FloatingActionButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:srcCompat="@drawable/ic_add" 
/>

instead of:

<android.support.design.widget.FloatingActionButton
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   app:srcCompat="@drawable/ic_add"

And all will work fine :)

You can limit mongod process usage using cgroups on Linux.

Using cgroups, our task can be accomplished in a few easy steps.

1. Create control group:

   cgcreate -g memory:DBLimitedGroup 
   

   (make sure that cgroups binaries installed on your system, consult your favorite Linux distribution manual for how to do that)

2. Specify how much memory will be available for this group:

   echo 16G > /sys/fs/cgroup/memory/DBLimitedGroup/memory.limit_in_bytes
   

   This command limits memory to 16G (good thing this limits the memory for both malloc allocations and OS cache)

3. Now, it will be a good idea to drop pages already stayed in cache:

   sync; echo 3 > /proc/sys/vm/drop_caches
   

4. And finally assign a server to created control group:

   cgclassify -g memory:DBLimitedGroup \`pidof mongod\`
   

   This will assign a running mongod process to a group limited by only 16GB memory.

You can create and dispatch keyboard events, and they will trigger appropriate registered event handlers, however they will not produce any text, if dispatched to input element for example.

To fully simulate text input you need to produce a sequence of keyboard events plus explicitly set the text of input element. The sequence of events depends on how thoroughly you want to simulate text input.

The simplest form would be:

$('input').val('123');
$('input').change();

You don't need to change the delimiter to display the right part of the string with cut.

The -f switch of the cut command is the n-TH element separated by your delimiter : :, so you can just type :

 grep puddle2_1557936 | cut -d ":" -f2

Another solutions (adapt it a bit) if you want fun :

Using grep :

grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                        
/home/rogers.williams/folderz/puddle2

or still with look around regex

grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                    
/home/rogers.williams/folderz/puddle2

or with perl :

perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                      
/home/rogers.williams/folderz/puddle2

or using ruby (thanks to glenn jackman)

ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with awk :

awk -F'puddle2_1557936:' '{print $2}'  <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with python :

python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or using only bash :

IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2

or using js in a shell :

js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2

or using php in a shell :

php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2' 
/home/rogers.williams/folderz/puddle2

You can wrap jQuery calls inside normal JavaScript code. So, for example:

$(document).ready(function() {
    if (someCondition && someOtherCondition) {
        // Make some jQuery call.
    }
});

This is what's killing you:

task.Wait();

That's blocking the UI thread until the task has completed - but the task is an async method which is going to try to get back to the UI thread after it "pauses" and awaits an async result. It can't do that, because you're blocking the UI thread...

There's nothing in your code which really looks like it needs to be on the UI thread anyway, but assuming you really do want it there, you should use:

private async void Button_Click(object sender, RoutedEventArgs 
{
    Task<List<MyObject>> task = GetResponse<MyObject>("my url");
    var items = await task;
    // Presumably use items here
}

Or just:

private async void Button_Click(object sender, RoutedEventArgs 
{
    var items = await GetResponse<MyObject>("my url");
    // Presumably use items here
}

Now instead of blocking until the task has completed, the Button_Click method will return after scheduling a continuation to fire when the task has completed. (That's how async/await works, basically.)

Note that I would also rename GetResponse to GetResponseAsync for clarity.

Jarret Hardie is correct. Or, first merge your changes back into master and then try the push. By default, git push pushes all branches that have names that match on the remote -- and no others. So those are your two choices -- either specify it explicitly like Jarret said or merge back to a common branch and then push.

There's been talk about this on the Git mail list and it's clear that this behavior is not about to change anytime soon -- many developers rely on this behavior in their workflows.

Edit/Clarification

Assuming your upstreammaster branch is ready to push then you could do this:

1. Pull in any changes from the upstream.

   $ git pull upstream master

2. Switch to my local master branch

   $ git checkout master

3. Merge changes in from upstreammaster

   $ git merge upstreammaster

4. Push my changes up

   $ git push upstream

Another thing that you may want to do before pushing is to rebase your changes against upstream/master so that your commits are all together. You can either do that as a separate step between #1 and #2 above (git rebase upstream/master) or you can do it as part of your pull (git pull --rebase upstream master)

Go to your activityMain and set the text by adding a widget from the widgets section and manually changing text by selecting and typing.

I created a container and set it the desired height of the view port (depending on the number of charts or chart specific sizes):

.graph-container {
width: 100%;
height: 30vh;
}

To be dynamic to screen sizes I set the container as follows:

*Small media devices specific styles*/
@media screen and (max-width: 800px) {
.graph-container {
        display: block;
        float: none;
        width: 100%;
        margin-top: 0px;
        margin-right:0px;
        margin-left:0px;
        height: auto;
    }
}

Of course very important (as have been referred to numerous times) set the following option properties of your chart:

options:{
    maintainAspectRatio: false,
    responsive: true,
}

Simple python script -

n = 1.923328437452
n = float(int(n * 1000))
n /=1000

Go via POSIXct and you want to set a TZ there -- here you see my (Chicago) default:

R> val <- 1352068320
R> as.POSIXct(val, origin="1970-01-01")
[1] "2012-11-04 22:32:00 CST"
R> as.Date(as.POSIXct(val, origin="1970-01-01"))
[1] "2012-11-05" 
R> 

Edit: A few years later, we can now use the anytime package:

R> library(anytime)
R> anytime(1352068320)
[1] "2012-11-04 16:32:00 CST"
R> anydate(1352068320)
[1] "2012-11-04"
R> 

Note how all this works without any format or origin arguments.

Edit 2020-06-15

Since data.table 1.12.4 (Oct 2019), data.table gains two functions to facilitate this: nafill and setnafill.

nafill operates on columns:

cols = c('a', 'b')
y[ , (cols) := lapply(.SD, nafill, fill=0), .SDcols = cols]

setnafill operates on tables (the replacements happen by-reference/in-place)

setnafill(y, cols=cols, fill=0)
# print y to show the effect
y[]

This will also be more efficient than the other options; see ?nafill for more, the last-observation-carried-forward (LOCF) and next-observation-carried-backward (NOCB) versions of NA imputation for time series.

This will work for your data.table version:

for (col in c("a", "b")) y[is.na(get(col)), (col) := 0]

Alternatively, as David Arenburg points out below, you can use set (side benefit - you can use it either on data.frame or data.table):

for (col in 1:2) set(x, which(is.na(x[[col]])), col, 0)

Had the same issues getting an authorization token on my Nexus 5 on Windows 8.1. I didn't have the latest adb driver installed - this is visible in device manager. Downloaded the latest ADB USB driver from Google here: http://developer.android.com/sdk/win-usb.html

Updated the driver in device manager, however enable/disable USB debugging and unplugging/plugging USB still did not work. Finally the "adb kill-server" and "adb start-server" mentioned in other answers did the trick once the driver was updated.

The following code shows that it is possible:

class OverridenStaticMeth {   

static void printValue() {   
System.out.println("Overriden Meth");   
}   

}   

public class OverrideStaticMeth extends OverridenStaticMeth {   

static void printValue() {   
System.out.println("Overriding Meth");   
}   

public static void main(String[] args) {   
OverridenStaticMeth osm = new OverrideStaticMeth();   
osm.printValue();   

System.out.println("now, from main");
printValue();

}   

} 

Besides just using include() or include_once() to include the header and footer, one thing I have found useful is being able to have a custom page title or custom head tags to be included for each page, yet still have the header in a partial include. I usually accomplish this as follows:

In the site pages:

<?php

$PageTitle="New Page Title";

function customPageHeader(){?>
  <!--Arbitrary HTML Tags-->
<?php }

include_once('header.php');

//body contents go here

include_once('footer.php');
?>

And, in the header.php file:

<!doctype html>
<html>
  <head>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
    <title><?= isset($PageTitle) ? $PageTitle : "Default Title"?></title>
    <!-- Additional tags here -->
    <?php if (function_exists('customPageHeader')){
      customPageHeader();
    }?>
  </head>
  <body>

Maybe a bit beyond the scope of your original question, but it is useful to allow a bit more flexibility with the include.

I use SQLYog at home and work. It turns out they DO have a free open-source version, though sadly they've been trying to hide that fact for the last few years.

You can download the open-source version from https://github.com/webyog/sqlyog-community - just click the "Download SQLyog Community Version" link.

You could try:

#applyCSS .ui-bar-a {property:value}
#applyCSS .ui-bar-a .ui-link-inherit {property:value}

Etc, etc... Is that what you're looking for?

My problem was solved when cancel event at end of grid event at server side.

protected void grdEducation_RowEditing(object sender, GridViewEditEventArgs e)

  // do your processing ...

  // at end<br />
  e.Cancel = true;
}

If you're getting this, you may have forgotten to put #include <thread> at the beginning of your file. OP's signature seems like it should work.

UTF-8 is not a character set, it's an encoding. The character set for UTF-8 is Unicode. If you want to store Unicode text you use the nvarchar data type.

If the database would use UTF-8 to store text, you would still not get the text out as encoded UTF-8 data, you would get it out as decoded text.

You can easily store UTF-8 encoded text in the database, but then you don't store it as text, you store it as binary data (varbinary).

Use document.activeElement

Should work.

P.S getElementById("myID") not getElementById("#myID")

You want a simple for loop:

total_count=0
for file in $(find . -name *.php -print)
do
    count=$(wc -l $file)
    let total_count+=count
done
echo "$total_count"

I recently created a library that uses annotations to generate those type casting boilerplate code for you. https://github.com/zeroarst/callbackfragment

Here is an example. Click a TextView on DialogFragment triggers a callback to MainActivity in onTextClicked then grab the MyFagment instance to interact with.

public class MainActivity extends AppCompatActivity implements MyFragment.FragmentCallback, MyDialogFragment.DialogListener {

private static final String MY_FRAGM = "MY_FRAGMENT";
private static final String MY_DIALOG_FRAGM = "MY_DIALOG_FRAGMENT";

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

    getSupportFragmentManager().beginTransaction()
        .add(R.id.lo_fragm_container, MyFragmentCallbackable.create(), MY_FRAGM)
        .commit();

    findViewById(R.id.bt).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            MyDialogFragmentCallbackable.create().show(getSupportFragmentManager(), MY_DIALOG_FRAGM);
        }
    });
}

Toast mToast;

@Override
public void onClickButton(MyFragment fragment) {
    if (mToast != null)
        mToast.cancel();
    mToast = Toast.makeText(this, "Callback from " + fragment.getTag() + " to " + this.getClass().getSimpleName(), Toast.LENGTH_SHORT);
    mToast.show();
}

@Override
public void onTextClicked(MyDialogFragment fragment) {
    MyFragment myFragm = (MyFragment) getSupportFragmentManager().findFragmentByTag(MY_FRAGM);
    if (myFragm != null) {
        myFragm.updateText("Callback from " + fragment.getTag() + " to " + myFragm.getTag());
    }
}

}

I solve this issue deleting the 10 packages in my android sdk manage.

if you are using subplots with bar charts, with different colour for each bar. it may be faster to create the artefacts yourself using mpatches

Say you have four bars with different colours as r m c k you can set the legend as follows

import matplotlib.patches as mpatches
import matplotlib.pyplot as plt
labels = ['Red Bar', 'Magenta Bar', 'Cyan Bar', 'Black Bar']


#####################################
# insert code for the subplots here #
#####################################


# now, create an artist for each color
red_patch = mpatches.Patch(facecolor='r', edgecolor='#000000') #this will create a red bar with black borders, you can leave out edgecolor if you do not want the borders
black_patch = mpatches.Patch(facecolor='k', edgecolor='#000000')
magenta_patch = mpatches.Patch(facecolor='m', edgecolor='#000000')
cyan_patch = mpatches.Patch(facecolor='c', edgecolor='#000000')
fig.legend(handles = [red_patch, magenta_patch, cyan_patch, black_patch],labels=labels,
       loc="center right", 
       borderaxespad=0.1)
plt.subplots_adjust(right=0.85) #adjust the subplot to the right for the legend

You could try this

SELECT RIGHT( '0' + convert( varchar(2) , '0' ),  2 ) -- OUTPUTS : 00
SELECT RIGHT( '0' + convert( varchar(2) , '8' ),  2 ) -- OUTPUTS : 08
SELECT RIGHT( '0' + convert( varchar(2) , '9' ),  2 ) -- OUTPUTS : 09
SELECT RIGHT( '0' + convert( varchar(2) , '10' ), 2 ) -- OUTPUTS : 10
SELECT RIGHT( '0' + convert( varchar(2) , '11' ), 2 ) -- OUTPUTS : 11

this should help

Swift 5 Very Easy way

//MARK:- First you need to encoded your arr or what ever object you want to save in UserDefaults
//in my case i want to save Picture (NMutableArray) in the User Defaults in

//first i have to encoded the NMutableArray 
let encodedData = NSKeyedArchiver.archivedData(withRootObject: yourArrayName)
//MARK:- Array save in UserDefaults

//MARK: Enjoy this arrry "yourArrayName"

From the MCTS self paced training kit exam 70-515 book:

With web application (project),

1. You can create an MVC application.
2. Visual Studio stores the list of files in a project file (.csproj or .vbproj), rather than relying on the folder structure.
3. You cannot mix Visual Basic and C#.
4. You cannot edit code without stopping a debugging session.
5. You can establish dependencies between multiple web projects.
6. You must compile the application before deployment, which prevents you from testing a page if another page will not compile.
7. You do not have to store the source code on the server.
8. You can control the assembly name and version.
9. You cannot edit individual files after deployment without recompiling.

In ASP.NET MVC 3 you can simply add your list to ViewData...

var options = new List<SelectListItem>();

options.Add(new SelectListItem { Value = "1", Text = "1" });
options.Add(new SelectListItem { Value = "2", Text = "2" });
options.Add(new SelectListItem { Value = "3", Text = "3", Selected = true });

ViewData["options"] = options;

...and then reference it by name in your razor view...

@Html.DropDownList("options")

You don't have to manually "use" the list in the DropDownList call. Doing it this way correctly set the selected value for me too.

Disclaimer:

1. Haven't tried this with the web forms view engine, but it should work too.
2. I haven't tested this in the v1 and v2, but it might work.

If you wish to convert a Pandas DataFrame to a table (list of lists) and include the header column this should work:

import pandas as pd
def dfToTable(df:pd.DataFrame) -> list:
    return [list(df.columns)] + df.values.tolist()

Usage (in REPL):

>>> df = pd.DataFrame(
             [["r1c1","r1c2","r1c3"],["r2c1","r2c2","r3c3"]]
             , columns=["c1", "c2", "c3"])
>>> df
     c1    c2    c3
0  r1c1  r1c2  r1c3
1  r2c1  r2c2  r3c3
>>> dfToTable(df)
[['c1', 'c2', 'c3'], ['r1c1', 'r1c2', 'r1c3'], ['r2c1', 'r2c2', 'r3c3']]

When you create the colorbar try using the fraction and/or shrink parameters.

From the documents:

fraction 0.15; fraction of original axes to use for colorbar

shrink 1.0; fraction by which to shrink the colorbar

There are two important concepts in multithreading environment:

1. atomicity
2. visibility

The volatile keyword eradicates visibility problems, but it does not deal with atomicity. volatile will prevent the compiler from reordering instructions which involve a write and a subsequent read of a volatile variable; e.g. k++. Here, k++ is not a single machine instruction, but three:

1. copy the value to a register;
2. increment the value;
3. place it back.

So, even if you declare a variable as volatile, this will not make this operation atomic; this means another thread can see a intermediate result which is a stale or unwanted value for the other thread.

On the other hand, AtomicInteger, AtomicReference are based on the Compare and swap instruction. CAS has three operands: a memory location V on which to operate, the expected old value A, and the new value B. CAS atomically updates V to the new value B, but only if the value in V matches the expected old value A; otherwise, it does nothing. In either case, it returns the value currently in V. The compareAndSet() methods of AtomicInteger and AtomicReference take advantage of this functionality, if it is supported by the underlying processor; if it is not, then the JVM implements it via spin lock.

You have it almost done. Just explicitly say where to create the file

@echo off
  echo.>"d:\testing\dblank.txt"

This creates a file containing a blank line (CR + LF = 2 bytes).

If you want the file empty (0 bytes)

@echo off
  break>"d:\testing\dblank.txt"

ou are able to create local variables once you call the render function on a partial, therefore if you want to customize a partial you can for example render the partial _form.html.erb by:

<%= render 'form', button_label: "Create New Event", url: new_event_url %>
<%= render 'form', button_label: "Update Event", url: edit_event_url %>

this way you can access in the partial to the label for the button and the URL, those are different if you try to create or update a record. finally, for accessing to this local variables you have to put in your code local_assigns[:button_label] (local_assigns[:name_of_your_variable])

<%=form_for(@event, url: local_assigns[:url]) do |f|  %>
<%= render 'shared/error_messages_events' %>
<%= f.label :title ,"Title"%>
  <%= f.text_field :title, class: 'form-control'%>
  <%=f.label :date, "Date"%>
  <%=f.date_field :date, class: 'form-control'  %>
  <%=f.label :description, "Description"%>
  <%=f.text_area :description, class: 'form-control'  %>
  <%= f.submit local_assigns[:button_label], class:"btn btn-primary"%>
<%end%>

As mentioned above, edit the application host.config. An easy way to find this is run your site in VS using IIS Express. Right click the systray icon, show all applications. Choose your site, and then click on the config link at the bottom to open it.

I'd suggest adding another binding entry, and leave the initial localhost one there. This additional binding will appear in the IIS Express systray as a separate application under the site.

To avoid having to run VS as admin (lots of good reasons not to run as admin), add a netsh rule as follows (obviously replacing the IP and port with your values) - you'll need an admin cmd.exe for this, it only needs to be run once:

netsh http add urlacl url=http://192.168.1.121:51652/ user=\Everyone

netsh can add rules like url=http://+:51652/ but I failed to get this to place nicely with IIS Express. You can use netsh http show urlacl to list existing rules, and they can be deleted with netsh http delete urlacl url=blah.

I answered my problem with a default width for all columns and cells, like below:

There are two possible result rearrangements (following example by @eumiro). Einops package provides a powerful notation to describe such operations non-ambigously

>> a = np.arange(18).reshape(9,2)

# this version corresponds to eumiro's answer
>> einops.rearrange(a, '(x y) z -> z y x', x=3)

array([[[ 0,  6, 12],
        [ 2,  8, 14],
        [ 4, 10, 16]],

       [[ 1,  7, 13],
        [ 3,  9, 15],
        [ 5, 11, 17]]])

# this has the same shape, but order of elements is different (note that each paer was trasnposed)
>> einops.rearrange(a, '(x y) z -> z x y', x=3)

array([[[ 0,  2,  4],
        [ 6,  8, 10],
        [12, 14, 16]],

       [[ 1,  3,  5],
        [ 7,  9, 11],
        [13, 15, 17]]])

The isinstance built-in is the preferred way if you really must, but even better is to remember Python's motto: "it's easier to ask forgiveness than permission"!-) (It was actually Grace Murray Hopper's favorite motto;-). I.e.:

def my_print(text, begin, end):
    "Print 'text' in UPPER between 'begin' and 'end' in lower"
    try:
      print begin.lower() + text.upper() + end.lower()
    except (AttributeError, TypeError):
      raise AssertionError('Input variables should be strings')

This, BTW, lets the function work just fine on Unicode strings -- without any extra effort!-)

you can also covert int to str first and assign index to it then again convert it to int like this:

int(str(x)[n]) //where x is an integer value

All the answers above couldn't solve the problem in my case. My ImageView was placed in a customized UITableViewCell. Therefore I had also call the layoutIfNeeded() method from here. Example:

 class NameTableViewCell:UITableViewCell,UITextFieldDelegate { ...

 override func awakeFromNib() {

    self.layoutIfNeeded()
    profileImageView.layoutIfNeeded()

    profileImageView.isUserInteractionEnabled = true
    let square = profileImageView.frame.size.width < profileImageView.frame.height ? CGSize(width: profileImageView.frame.size.width, height: profileImageView.frame.size.width) : CGSize(width: profileImageView.frame.size.height, height:  profileImageView.frame.size.height)
    profileImageView.addGestureRecognizer(tapGesture)
    profileImageView.layer.cornerRadius = square.width/2
    profileImageView.clipsToBounds = true;
}

This is how I do. I have added explanation to understand what the heck is going on.

Initialize Local Repository

• first initialize Git with

  git init

• Add all Files for version control with

  git add .

• Create a commit with message of your choice

  git commit -m 'AddingBaseCode'

Initialize Remote Repository

• Create a project on GitHub and copy the URL of your project . as shown below:

  

Link Remote repo with Local repo

• Now use copied URL to link your local repo with remote GitHub repo. When you clone a repository with git clone, it automatically creates a remote connection called origin pointing back to the cloned repository. The command remote is used to manage set of tracked repositories.

  git remote add origin https://github.com/hiteshsahu/Hassium-Word.git

Synchronize

• Now we need to merge local code with remote code. This step is critical otherwise we won't be able to push code on GitHub. You must call 'git pull' before pushing your code.

  git pull origin master --allow-unrelated-histories

Commit your code

• Finally push all changes on GitHub

  git push -u origin master

Try:

  string output = YourString.replaceAll("\\s","")

s - indicates space character (tab characters etc)

Dim strPath As String = System.IO.Path.GetDirectoryName( _
    System.Reflection.Assembly.GetExecutingAssembly().CodeBase)

Taken from HOW TO: Determine the Executing Application's Path (MSDN)

If you want to achieve this (you can resize the window to see how it will look for mobile version), all you have to do is to have 2 logo images (1 for desktop and one for mobile) and display them depending of the enviroment using visible-xs and hidden-xs classes.

So i used something like this:

<img class="hidden-xs" src="http://placehold.it/150x50&text=Logo" alt="">
<img class="visible-xs" src="http://placehold.it/120x40&text=Logo" alt=""> 

And ofcourse, i styled the mobile logo using:

@media (max-width: 767px) { 
    .navbar-brand {
        padding: 0;        
    }

    .navbar-brand img {
        margin-top: 5px;
        margin-left: 5px;
    }
}

You can see all the code here. In case you need a text on mobile version insted of the logo, it's not a big deal. Just replace the logo with a <h1 class="visible-xs">AppName</h3> and change the style inside the media query like this:

@media (max-width: 767px) { 
    .navbar-brand {
        padding: 0;        
    }

    .navbar-brand h1{
        //here add your style depending of the position you want the text to be placed
    }
} 

EDIT:

You need this conditions to make it work:

.navbar-toggle {
   margin: 23px 0; 
}

.navbar-nav, .navbar-nav li, .navbar-nav li a {
  height: 80px;
  line-height: 80px;
}

.navbar-nav li a {
  padding-top: 0;
  padding-bottom:0;
}

As mentioned earlier, you can use the grid system to layout your inputs and labels anyway that you want. The trick is to remember that you can use rows within your columns to break them into twelfths as well.

The example below is one possible way to accomplish your goal and will put the two text boxes near Label3 on the same line when the screen is small or larger.

Java 8+ version:

Files.createDirectories(Paths.get("/Your/Path/Here"));

The Files.createDirectories() creates a new directory and parent directories that do not exist. This method does not throw an exception if the directory already exists.

in Jquery "data" doesn't refresh by default :

alert($('#outer').html());
var a = $('#mydiv').data('myval'); //getter
$('#mydiv').data("myval","20"); //setter
alert($('#outer').html());

You'd use "attr" instead for live update:

alert($('#outer').html());
var a = $('#mydiv').data('myval'); //getter
$('#mydiv').attr("data-myval","20"); //setter
alert($('#outer').html());

Just install the server certificate in the client's trusted root certificates container (if certified it's expired may not work). For further details see this post of similar question.

https://stackoverflow.com/a/21238125/3215589

The code works for me. (after adding missing except clause / import statements)

Did you put \ in the original code?

urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' \
              + stock + '/chartdata;type=quote;range=5d/csv'

If you omit it, it could be a cause of the exception:

>>> stock = 'GOOG'
>>> urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/'
>>> + stock + '/chartdata;type=quote;range=5d/csv'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary +: 'str'

BTW, string(e) should be str(e).

There's no easy way to do it, and like @alex has noted you'll need to use JavaScript. His answer is the best solution but in order to optimize it, you might want to filter only to the post-content links.

<script>
    var links = document.querySelectorAll( '.post-content a' );  
    for (var i = 0, length = links.length; i < length; i++) {  
        if (links[i].hostname != window.location.hostname) {
            links[i].target = '_blank';
        }
    }
</script>

The code is compatible with IE8+ and you can add it to the bottom of your page. Note that you'll need to change the ".post-content a" to the class that you're using for your posts.

Here is a solution based on the powerful but poorly documented logging.config.dictConfig method. Instead of sending every log message to stdout, it sends messages with log level ERROR and higher to stderr and everything else to stdout. This can be useful if other parts of the system are listening to stderr or stdout.

import logging
import logging.config
import sys

class _ExcludeErrorsFilter(logging.Filter):
    def filter(self, record):
        """Only returns log messages with log level below ERROR (numeric value: 40)."""
        return record.levelno < 40


config = {
    'version': 1,
    'filters': {
        'exclude_errors': {
            '()': _ExcludeErrorsFilter
        }
    },
    'formatters': {
        # Modify log message format here or replace with your custom formatter class
        'my_formatter': {
            'format': '(%(process)d) %(asctime)s %(name)s (line %(lineno)s) | %(levelname)s %(message)s'
        }
    },
    'handlers': {
        'console_stderr': {
            # Sends log messages with log level ERROR or higher to stderr
            'class': 'logging.StreamHandler',
            'level': 'ERROR',
            'formatter': 'my_formatter',
            'stream': sys.stderr
        },
        'console_stdout': {
            # Sends log messages with log level lower than ERROR to stdout
            'class': 'logging.StreamHandler',
            'level': 'DEBUG',
            'formatter': 'my_formatter',
            'filters': ['exclude_errors'],
            'stream': sys.stdout
        },
        'file': {
            # Sends all log messages to a file
            'class': 'logging.FileHandler',
            'level': 'DEBUG',
            'formatter': 'my_formatter',
            'filename': 'my.log',
            'encoding': 'utf8'
        }
    },
    'root': {
        # In general, this should be kept at 'NOTSET'.
        # Otherwise it would interfere with the log levels set for each handler.
        'level': 'NOTSET',
        'handlers': ['console_stderr', 'console_stdout', 'file']
    },
}

logging.config.dictConfig(config)

For the same issue, I used an easy solution : put a padding-top of 40px on each anchor.

1. Add using

using System.ComponentModel;

2. Declare Background Worker:

private readonly BackgroundWorker worker = new BackgroundWorker();

3. Subscribe to events:

worker.DoWork += worker_DoWork;
worker.RunWorkerCompleted += worker_RunWorkerCompleted;

4. Implement two methods:

private void worker_DoWork(object sender, DoWorkEventArgs e)
{
  // run all background tasks here
}

private void worker_RunWorkerCompleted(object sender, 
                                           RunWorkerCompletedEventArgs e)
{
  //update ui once worker complete his work
}

5. Run worker async whenever your need.

worker.RunWorkerAsync();

6. Track progress (optional, but often useful)

   a) subscribe to ProgressChanged event and use ReportProgress(Int32) in DoWork

   b) set worker.WorkerReportsProgress = true; (credits to @zagy)

If you don't want to calculate it using java's Calendar you can use Androids Time class It is supposed to be faster but I didn't notice much difference when i switched.

I could not find any pre-defined functions to determine time between 2 dates for an age in Android. There are some nice helper functions to get formatted time between dates in the DateUtils but that's probably not what you want.

Update

Apple has clarified that slicing occurs independent of enabling bitcode. I've observed this in practice as well where a non-bitcode enabled app will only be downloaded as the architecture appropriate for the target device.

Original

More specifically:

Bitcode. Archive your app for submission to the App Store in an intermediate representation, which is compiled into 64- or 32-bit executables for the target devices when delivered.

Slicing. Artwork incorporated into the Asset Catalog and tagged for a platform allows the App Store to deliver only what is needed for installation.

The way I read this, if you support bitcode, downloaders of your app will only get the compiled architecture needed for their own device.

This will check if particular email address exist in the table:

if (isset(User::where('email', Input::get('email'))->value('email')))
{
    // Input::get('email') exist in the table 
}

Q. Why would I choose this answer?

• Choose this answer if you want the fastest speed .NET is capable of.
• Ignore this answer if you want a really, really easy method of cloning.

In other words, go with another answer unless you have a performance bottleneck that needs fixing, and you can prove it with a profiler.

10x faster than other methods

The following method of performing a deep clone is:

• 10x faster than anything that involves serialization/deserialization;
• Pretty darn close to the theoretical maximum speed .NET is capable of.

And the method ...

For ultimate speed, you can use Nested MemberwiseClone to do a deep copy. Its almost the same speed as copying a value struct, and is much faster than (a) reflection or (b) serialization (as described in other answers on this page).

Note that if you use Nested MemberwiseClone for a deep copy, you have to manually implement a ShallowCopy for each nested level in the class, and a DeepCopy which calls all said ShallowCopy methods to create a complete clone. This is simple: only a few lines in total, see the demo code below.

Here is the output of the code showing the relative performance difference for 100,000 clones:

• 1.08 seconds for Nested MemberwiseClone on nested structs
• 4.77 seconds for Nested MemberwiseClone on nested classes
• 39.93 seconds for Serialization/Deserialization

Using Nested MemberwiseClone on a class almost as fast as copying a struct, and copying a struct is pretty darn close to the theoretical maximum speed .NET is capable of.

Demo 1 of shallow and deep copy, using classes and MemberwiseClone:
  Create Bob
    Bob.Age=30, Bob.Purchase.Description=Lamborghini
  Clone Bob >> BobsSon
  Adjust BobsSon details
    BobsSon.Age=2, BobsSon.Purchase.Description=Toy car
  Proof of deep copy: If BobsSon is a true clone, then adjusting BobsSon details will not affect Bob:
    Bob.Age=30, Bob.Purchase.Description=Lamborghini
  Elapsed time: 00:00:04.7795670,30000000

Demo 2 of shallow and deep copy, using structs and value copying:
  Create Bob
    Bob.Age=30, Bob.Purchase.Description=Lamborghini
  Clone Bob >> BobsSon
  Adjust BobsSon details:
    BobsSon.Age=2, BobsSon.Purchase.Description=Toy car
  Proof of deep copy: If BobsSon is a true clone, then adjusting BobsSon details will not affect Bob:
    Bob.Age=30, Bob.Purchase.Description=Lamborghini
  Elapsed time: 00:00:01.0875454,30000000

Demo 3 of deep copy, using class and serialize/deserialize:
  Elapsed time: 00:00:39.9339425,30000000

To understand how to do a deep copy using MemberwiseCopy, here is the demo project that was used to generate the times above:

// Nested MemberwiseClone example. 
// Added to demo how to deep copy a reference class.
[Serializable] // Not required if using MemberwiseClone, only used for speed comparison using serialization.
public class Person
{
    public Person(int age, string description)
    {
        this.Age = age;
        this.Purchase.Description = description;
    }
    [Serializable] // Not required if using MemberwiseClone
    public class PurchaseType
    {
        public string Description;
        public PurchaseType ShallowCopy()
        {
            return (PurchaseType)this.MemberwiseClone();
        }
    }
    public PurchaseType Purchase = new PurchaseType();
    public int Age;
    // Add this if using nested MemberwiseClone.
    // This is a class, which is a reference type, so cloning is more difficult.
    public Person ShallowCopy()
    {
        return (Person)this.MemberwiseClone();
    }
    // Add this if using nested MemberwiseClone.
    // This is a class, which is a reference type, so cloning is more difficult.
    public Person DeepCopy()
    {
            // Clone the root ...
        Person other = (Person) this.MemberwiseClone();
            // ... then clone the nested class.
        other.Purchase = this.Purchase.ShallowCopy();
        return other;
    }
}
// Added to demo how to copy a value struct (this is easy - a deep copy happens by default)
public struct PersonStruct
{
    public PersonStruct(int age, string description)
    {
        this.Age = age;
        this.Purchase.Description = description;
    }
    public struct PurchaseType
    {
        public string Description;
    }
    public PurchaseType Purchase;
    public int Age;
    // This is a struct, which is a value type, so everything is a clone by default.
    public PersonStruct ShallowCopy()
    {
        return (PersonStruct)this;
    }
    // This is a struct, which is a value type, so everything is a clone by default.
    public PersonStruct DeepCopy()
    {
        return (PersonStruct)this;
    }
}
// Added only for a speed comparison.
public class MyDeepCopy
{
    public static T DeepCopy<T>(T obj)
    {
        object result = null;
        using (var ms = new MemoryStream())
        {
            var formatter = new BinaryFormatter();
            formatter.Serialize(ms, obj);
            ms.Position = 0;
            result = (T)formatter.Deserialize(ms);
            ms.Close();
        }
        return (T)result;
    }
}

Then, call the demo from main:

void MyMain(string[] args)
{
    {
        Console.Write("Demo 1 of shallow and deep copy, using classes and MemberwiseCopy:\n");
        var Bob = new Person(30, "Lamborghini");
        Console.Write("  Create Bob\n");
        Console.Write("    Bob.Age={0}, Bob.Purchase.Description={1}\n", Bob.Age, Bob.Purchase.Description);
        Console.Write("  Clone Bob >> BobsSon\n");
        var BobsSon = Bob.DeepCopy();
        Console.Write("  Adjust BobsSon details\n");
        BobsSon.Age = 2;
        BobsSon.Purchase.Description = "Toy car";

        Console.Write("  Proof of deep copy: If BobsSon is a true clone, then adjusting BobsSon details will not affect Bob:\n");
        Console.Write("    Bob.Age={0}, Bob.Purchase.Description={1}\n", Bob.Age, Bob.Purchase.Description);

        var sw = new Stopwatch();
        sw.Start();
        int total = 0;
        for (int i = 0; i < 100000; i++)
        {
            var n = Bob.DeepCopy();
            total += n.Age;
        }
        Console.Write("  Elapsed time: {0},{1}\n\n", sw.Elapsed, total);
    }
    {

        var Bob = new PersonStruct(30, "Lamborghini");
        Console.Write("  Create Bob\n");

        Console.Write("  Clone Bob >> BobsSon\n");
        var BobsSon = Bob.DeepCopy();
        Console.Write("  Adjust BobsSon details:\n");
        BobsSon.Age = 2;
        BobsSon.Purchase.Description = "Toy car";
        Console.Write("    BobsSon.Age={0}, BobsSon.Purchase.Description={1}\n", BobsSon.Age, BobsSon.Purchase.Description);
        Console.Write("  Proof of deep copy: If BobsSon is a true clone, then adjusting BobsSon details will not affect Bob:\n");
        Console.Write("    Bob.Age={0}, Bob.Purchase.Description={1}\n", Bob.Age, Bob.Purchase.Description);                
        Debug.Assert(Bob.Age == 30);
        Debug.Assert(Bob.Purchase.Description == "Lamborghini");
        var sw = new Stopwatch();
        sw.Start();
        int total = 0;
        for (int i = 0; i < 100000; i++)
        {
            var n = Bob.DeepCopy();
            total += n.Age;
        }
        Console.Write("  Elapsed time: {0},{1}\n\n", sw.Elapsed, total);
    }
    {

        var Bob = new Person(30, "Lamborghini");
        for (int i = 0; i < 100000; i++)
        {
            var BobsSon = MyDeepCopy.DeepCopy<Person>(Bob);
            total += BobsSon.Age;
        }
        Console.Write("  Elapsed time: {0},{1}\n", sw.Elapsed, total);
    }
    Console.ReadKey();
}

Again, note that if you use Nested MemberwiseClone for a deep copy, you have to manually implement a ShallowCopy for each nested level in the class, and a DeepCopy which calls all said ShallowCopy methods to create a complete clone. This is simple: only a few lines in total, see the demo code above.

Value types vs. References Types

Note that when it comes to cloning an object, there is is a big difference between a "struct" and a "class":

• If you have a "struct", it's a value type so you can just copy it, and the contents will be cloned (but it will only make a shallow clone unless you use the techniques in this post).
• If you have a "class", it's a reference type, so if you copy it, all you are doing is copying the pointer to it. To create a true clone, you have to be more creative, and use differences between value types and references types which creates another copy of the original object in memory.

See differences between value types and references types.

Checksums to aid in debugging

• Cloning objects incorrectly can lead to very difficult-to-pin-down bugs. In production code, I tend to implement a checksum to double check that the object has been cloned properly, and hasn't been corrupted by another reference to it. This checksum can be switched off in Release mode.
• I find this method quite useful: often, you only want to clone parts of the object, not the entire thing.

Really useful for decoupling many threads from many other threads

One excellent use case for this code is feeding clones of a nested class or struct into a queue, to implement the producer / consumer pattern.

• We can have one (or more) threads modifying a class that they own, then pushing a complete copy of this class into a ConcurrentQueue.
• We then have one (or more) threads pulling copies of these classes out and dealing with them.

This works extremely well in practice, and allows us to decouple many threads (the producers) from one or more threads (the consumers).

And this method is blindingly fast too: if we use nested structs, it's 35x faster than serializing/deserializing nested classes, and allows us to take advantage of all of the threads available on the machine.

Update

Apparently, ExpressMapper is as fast, if not faster, than hand coding such as above. I might have to see how they compare with a profiler.

More actual solution:

<a id="someId">Link</a>

const a = document.querySelector('#someId');
a.href = 'url';

moment("01:15:00 PM", "h:mm:ss A").format("HH:mm:ss")
**o/p: 13:15:00 **

it will give convert 24 hrs format to 12 hrs format.

May be the file you have created is outside the src(source) folder. Trying to call the class object(from the file located in the src folder) from the .java file outside the source folder results in the same error. Copy .java file to the source folder, then build it. The error will be gone.

Select into creates new table for you at the time and then insert records in it from the source table. The newly created table has the same structure as of the source table.If you try to use select into for a existing table it will produce a error, because it will try to create new table with the same name. Insert into requires the table to be exist in your database before you insert rows in it.

egit was included in Indigo (2011) and should be there in all future Eclipse versions after that.

Just go to ![(Help->Install New Software)]

Then Work with: --All Available Sites--

Then type egit underneath and wait (may take a while) ! Then click the checkbox and install.

Application Programming Interface is a set of routines/data structures/classes which specifies a way to interact with the target platform/software like OS X, Android, project management application, virtualization software etc.

While Software Development Kit is a wrapper around API/s that makes the job easy for developers.

For example, Android SDK facilitates developers to interact with the Android platform as a whole while the platform itself is built by composite software components communicating via APIs.

Also, sometimes SDKs are built to facilitate development in a specific programming language. For example, Selenium web driver (built in Java) provides APIs to drive any browser natively, while capybara can be considered an an SDK that facilitates Ruby developers to use Selenium web driver. However, Selenium web driver is also an SDK by itself as it combines interaction with various native browser drivers into one package.

only with JS

 let select=document.querySelectorAll('select') 
  select.forEach(function(el) {
    el.onchange =  function(){
     alert(this.value);
      
  }}
  )

The destructor for the object of class A will only be called if delete is called for that object. Make sure to delete that pointer in the destructor of class B.

For a little more information on what happens when delete is called on an object, see: http://www.parashift.com/c++-faq-lite/freestore-mgmt.html#faq-16.9

The suggestion from @Dawood is good if that works for you.

If you need more fine-tuning than that, one option is to use padding on the text elements, here's an example: http://jsfiddle.net/panchroma/FtBwe/

CSS

p, h2 {
    padding-left:10px;
}

randomNumber function return unqiue integer value between 0 to 100000

  bool check[] = new bool[100001];
  Random r = new Random();
  public int randomNumber() {
      int num = r.Next(0,100000);
       while(check[num] == true) {
             num = r.Next(0,100000);
     }
    check[num] = true;
   return num;
 }

<script>
var todayDate = new Date();
var getTodayDate = todayDate.getDate();
var getTodayMonth =  todayDate.getMonth()+1;
var getTodayFullYear = todayDate.getFullYear();
var getCurrentHours = todayDate.getHours();
var getCurrentMinutes = todayDate.getMinutes();
var getCurrentAmPm = getCurrentHours >= 12 ? 'PM' : 'AM';
getCurrentHours = getCurrentHours % 12;
getCurrentHours = getCurrentHours ? getCurrentHours : 12; 
getCurrentMinutes = getCurrentMinutes < 10 ? '0'+getCurrentMinutes : getCurrentMinutes;
var getCurrentDateTime = getTodayDate + '-' + getTodayMonth + '-' + getTodayFullYear + ' ' + getCurrentHours + ':' + getCurrentMinutes + ' ' + getCurrentAmPm;
alert(getCurrentDateTime);
</script>

Since the settings object is tied to that ajax call, you can simply add in the indexer as a custom property, which you can then access using this in the success callback:

//preloader for images on gallery pages
window.onload = function() {
    var urls = ["./img/party/","./img/wedding/","./img/wedding/tree/"];

    setTimeout(function() {
        for ( var i = 0; i < urls.length; i++ ) {
            $.ajax({
                url: urls[i],
                indexValue: i,
                success: function(data) {
                    image_link(data , this.indexValue);

                    function image_link(data, i) {
                        $(data).find("a:contains(.jpg)").each(function(){ 
                            console.log(i);
                            new Image().src = urls[i] + $(this).attr("href");
                        });
                    }
                }
            });
        };  
    }, 1000);       
};

Edit: Adding in an updated JSFiddle example, as they seem to have changed how their ECHO endpoints work: https://jsfiddle.net/djujx97n/26/.

To understand how this works see the "context" field on the ajaxSettings object: http://api.jquery.com/jquery.ajax/, specifically this note:

"The this reference within all callbacks is the object in the context option passed to $.ajax in the settings; if context is not specified, this is a reference to the Ajax settings themselves."

Use logging:

import unittest
import logging
import inspect
import os

logging_level = logging.INFO

try:
    log_file = os.environ["LOG_FILE"]
except KeyError:
    log_file = None

def logger(stack=None):
    if not hasattr(logger, "initialized"):
        logging.basicConfig(filename=log_file, level=logging_level)
        logger.initialized = True
    if not stack:
        stack = inspect.stack()
    name = stack[1][3]
    try:
        name = stack[1][0].f_locals["self"].__class__.__name__ + "." + name
    except KeyError:
        pass
    return logging.getLogger(name)

def todo(msg):
    logger(inspect.stack()).warning("TODO: {}".format(msg))

def get_pi():
    logger().info("sorry, I know only three digits")
    return 3.14

class Test(unittest.TestCase):

    def testName(self):
        todo("use a better get_pi")
        pi = get_pi()
        logger().info("pi = {}".format(pi))
        todo("check more digits in pi")
        self.assertAlmostEqual(pi, 3.14)
        logger().debug("end of this test")
        pass

Usage:

# LOG_FILE=/tmp/log python3 -m unittest LoggerDemo
.
----------------------------------------------------------------------
Ran 1 test in 0.047s

OK
# cat /tmp/log
WARNING:Test.testName:TODO: use a better get_pi
INFO:get_pi:sorry, I know only three digits
INFO:Test.testName:pi = 3.14
WARNING:Test.testName:TODO: check more digits in pi

If you do not set LOG_FILE, logging will got to stderr.

Don't know why people are using so complex methods to achieve such a simple thing! And regex? Wow!

Here you go, the easiest and simplest way (as explained here: https://nabtron.com/kiss-code/ ):

$a = '000000000000001';
$a += 0;

echo $a; // will output 1

In Windows or Linux, you can use this command:

spark-shell --driver-memory 2G

MVP:

Advantages:

Presenter will be present in between Model and view.Presenter will fetch data from Model and will do manipulations for data as view wants and give it to view and view is responsible only for rendering.

Disadvantages:

1)We can't use presenter for multiple modules because data is being modified in presenter as desired by one view class.

3)Breaking Clean architecture because data flow should be only outwards but here data is coming back from presenter to View.

MVC:

Advanatages:

Here we have Controller in between view and model.Here data request will be done from controller to view but data will be sent back to view in form of interface but not with controller.So,here controller won't get bloated up because of many transactions.

Disadvantagaes:

Data Manipulation should be done by View as it wants and this will be extra work on UI thread which may effect UI rendering if data processing is more.

MVVM:

After announcing Architectural components,we got access to ViewModel which provided us biggest advantage i.e it's lifecycle aware.So,it won't notify data if view is not available.It is a clean architecture because flow is only in forward mode and data will be notified automatically by LiveData. So,it is Android's recommended architecture.

Even MVVM has a disadvantage. Since it is a lifecycle aware some concepts like alarm or reminder should come outside app.So,in this scenario we can't use MVVM.

hash[:new_key] = hash.delete :old_key

I'd define that I want a maximum number of non-] characters between [ and ]. These need to be escaped with backslashes (and in Java, these need to be escaped again), and the definition of non-] is a character class, thus inside [ and ] (i.e. [^\\]]). The result:

FOO\\[([^\\]]+)\\]

Update 2020:

I've been really enjoying phin - The ultra-lightweight Node.js HTTP client

It can be used in two different ways. One with Promises (Async/Await) and the other with traditional callback styles.

Install via: npm i phin

Straight from it's README with await:

const p = require('phin')

await p({
    url: 'https://ethanent.me',
    method: 'POST',
    data: {
        hey: 'hi'
    }
})

Unpromisifed (callback) style:

const p = require('phin').unpromisified

p('https://ethanent.me', (err, res) => {
    if (!err) console.log(res.body)
})

As of 2015 there are now a wide variety of different libraries that can accomplish this with minimal coding. I much prefer elegant light weight libraries for HTTP requests unless you absolutely need control of the low level HTTP stuff.

One such library is Unirest

To install it, use npm.
$ npm install unirest

And onto the Hello, World! example that everyone is accustomed to.

var unirest = require('unirest');

unirest.post('http://example.com/helloworld')
.header('Accept', 'application/json')
.send({ "Hello": "World!" })
.end(function (response) {
  console.log(response.body);
});

Extra:
A lot of people are also suggesting the use of request [ 2 ]

It should be worth noting that behind the scenes Unirest uses the request library.

Unirest provides methods for accessing the request object directly.

Example:

var Request = unirest.get('http://mockbin.com/request');

well, it is not really necessary to create a function for this when it can be done simply with 1 CSS class.

just wrap your text around this class and see the magic :D

 <p style={{whiteSpace: 'pre-line'}}>my json text goes here \n\n</p>

note: because you will always present your text in frontend with HTML you can add the style={{whiteSpace: 'pre-line'}} to any tag, not just the p tag.

Use the following line

android:nextFocusDown="@+id/parentedit"

parentedit is the ID of the next EditText to be focused.

The above line will also need the following line.

android:inputType="text"

or

android:inputType="number"

Thanks for the suggestion @Alexei Khlebnikov.

This is exactly what the in operator is for. Use it like this:

if (index in currentData) 
{ 
    Ti.API.info(index + " exists: " + currentData[index]);
}

The accepted answer is wrong, it will give a false negative if the value at index is undefined:

const currentData = ['a', undefined], index = 1;_x000D_
_x000D_
if (index in currentData) {_x000D_
  console.info('exists');_x000D_
}_x000D_
// ...vs..._x000D_
if (typeof currentData[index] !== 'undefined') {_x000D_
  console.info('exists');_x000D_
} else {_x000D_
  console.info('does not exist'); // incorrect!_x000D_
}

Because nil cannot be stored in Foundation data structures NSNull is sometimes to represent a nil. Because NSNull is a singleton object you can check to see if NSNull is the value stored in dictionary by using direct pointer comparison:

if ((NSNull *)[user objectForKey:@"myKey"] == [NSNull null]) { }

FAT32 along with FAT16 and FAT12 are File System Types, but vfat along with umsdos and msdos are drivers, used to mount the FAT file systems in Linux. The choosing of the driver determines how some of the features are applied to the file system, for example, systems mounted with msdos driver don't have long filenames (they are 8.3 format). vfat is the most common driver for mounting FAT32 file systems nowadays.

Source: this wikipedia article

Output of commands like df and lsblk indeed show vfat as the File System Type. But sudo file -sL /dev/<partition> shows FAT (32 bit) if a File System is FAT32.

You can confirm vfat is a module and not a File System Type by running modinfo vfat.
