Many people have already given you good answers to solve this but I have not read any using list comprehension so I give you what I used for a similar use case :

def compute_months(first_date, second_date):
    year1, month1, year2, month2 = map(
        int, 
        (first_date[:4], first_date[5:7], second_date[:4], second_date[5:7])
    )

    return [
        '{:0>4}-{:0>2}'.format(year, month)
        for year in range(year1, year2 + 1)
        for month in range(month1 if year == year1 else 1, month2 + 1 if year == year2 else 13)
    ]

>>> first_date = "2016-05"
>>> second_date = "2017-11"
>>> compute_months(first_date, second_date)
['2016-05',
 '2016-06',
 '2016-07',
 '2016-08',
 '2016-09',
 '2016-10',
 '2016-11',
 '2016-12',
 '2017-01',
 '2017-02',
 '2017-03',
 '2017-04',
 '2017-05',
 '2017-06',
 '2017-07',
 '2017-08',
 '2017-09',
 '2017-10',
 '2017-11']

John Conde does all the right procedures in his method but doesn't satisfy the final step in your question which is to format the result to your specifications.

This code (Demo) will display the raw difference, expose the trouble with trying to immediately format the raw difference, display my preparation steps, and finally present the correctly formatted result:

$datetime1 = new DateTime('2017-04-26 18:13:06');
$datetime2 = new DateTime('2011-01-17 17:13:00');  // change the millenium to see output difference
$diff = $datetime1->diff($datetime2);

// this will get you very close, but it will not pad the digits to conform with your expected format
echo "Raw Difference: ",$diff->format('%y years %m months %d days %h hours %i minutes %s seconds'),"\n";

// Notice the impact when you change $datetime2's millenium from '1' to '2'
echo "Invalid format: ",$diff->format('%Y-%m-%d %H:%i:%s'),"\n";  // only H does it right

$details=array_intersect_key((array)$diff,array_flip(['y','m','d','h','i','s']));

echo '$detail array: ';
var_export($details);
echo "\n";

array_map(function($v,$k)
    use(&$r)
    {
        $r.=($k=='y'?str_pad($v,4,"0",STR_PAD_LEFT):str_pad($v,2,"0",STR_PAD_LEFT));
        if($k=='y' || $k=='m'){$r.="-";}
        elseif($k=='d'){$r.=" ";}
        elseif($k=='h' || $k=='i'){$r.=":";}
    },$details,array_keys($details)
);
echo "Valid format: ",$r; // now all components of datetime are properly padded

Output:

Raw Difference: 6 years 3 months 9 days 1 hours 0 minutes 6 seconds
Invalid format: 06-3-9 01:0:6
$detail array: array (
  'y' => 6,
  'm' => 3,
  'd' => 9,
  'h' => 1,
  'i' => 0,
  's' => 6,
)
Valid format: 0006-03-09 01:00:06

Now to explain my datetime value preparation:

$details takes the diff object and casts it as an array. array_flip(['y','m','d','h','i','s']) creates an array of keys which will be used to remove all irrelevant keys from (array)$diff using array_intersect_key().

Then using array_map() my method iterates each value and key in $details, pads its left side to the appropriate length with 0's, and concatenates the $r (result) string with the necessary separators to conform with requested datetime format.

An __init__.py file makes imports easy. When an __init__.py is present within a package, function a() can be imported from file b.py like so:

from b import a

Without it, however, you can't import directly. You have to amend the system path:

import sys
sys.path.insert(0, 'path/to/b.py')

from b import a

@jennifer06262016, you can definitely add another filter to return the objects inside a django Queryset.

@register.filter 
def get_item(Queryset):
    return Queryset.your_item_key

In that case, you would type something like this {{ Queryset|index:x|get_item }} into your template to access some dictionary object. It works for me.

Since Jackson is being used, you have to configure that as a Jackson property. In the case of Spring Boot REST services, you have to configure it in application.properties or application.yml:

spring.jackson.default-property-inclusion = NON_NULL

source

For this you have to use HtmlAttributes, but there is a catch: HtmlAttributes and css class .

you can define it like this:

new { Attrubute="Value", AttributeTwo = IntegerValue, @class="className" };

and here is a more realistic example:

new { style="width:50px" };
new { style="width:50px", maxsize = 50 };
new {size=30, @class="required"}

and finally in:

MVC 1

<%= Html.TextBox("test", new { style="width:50px" }) %> 

MVC 2

<%= Html.TextBox("test", null, new { style="width:50px" }) %> 

MVC 3

@Html.TextBox("test", null, new { style="width:50px" })

In one of my comments to an answer I lamented that I've long wanted some way to print all the significant digits in a floating point value in decimal form, in much the same way the as the question asks. Well I finally sat down and wrote it. It's not quite perfect, and this is demo code that prints additional information, but it mostly works for my tests. Please let me know if you (i.e. anyone) would like a copy of the whole wrapper program which drives it for testing.

static unsigned int
ilog10(uintmax_t v);

/*
 * Note:  As presented this demo code prints a whole line including information
 * about how the form was arrived with, as well as in certain cases a couple of
 * interesting details about the number, such as the number of decimal places,
 * and possibley the magnitude of the value and the number of significant
 * digits.

         * number, then we must calculate the correct number of decimal places
         * to show with "%.*f" as follows.
         *
         * This is in lieu of always using either full on scientific notation
         * with "%e" (where the presentation is always in decimal format so we
         * can directly print the maximum number of significant digits

         *        printf("%1.*e", DBL_DECIMAL_DIG - 1, d)

Best way to do it in 2019 is by using .includes()

[1, 2, 3].includes(2);     // true
[1, 2, 3].includes(4);     // false
[1, 2, 3].includes(1, 2);  // false

First parameter is what you are searching for. Second parameter is the index position in this array at which to begin searching.

Agree with dfa, that's why i consider the prototye as the class when no named class found

Here is an upgraded function of the one posted by Eli Grey, to match my way of mind

function what(obj){
    if(typeof(obj)==="undefined")return "undefined";
    if(obj===null)return "Null";
    var res = Object.prototype.toString.call(obj).match(/^\[object\s(.*)\]$/)[1];
    if(res==="Object"){
        res = obj.constructor.name;
        if(typeof(res)!='string' || res.length==0){
            if(obj instanceof jQuery)return "jQuery";// jQuery build stranges Objects
            if(obj instanceof Array)return "Array";// Array prototype is very sneaky
            return "Object";
        }
    }
    return res;
}

Faced this scenario using Git Bash.

Our repository has multiple branches and each branch has a different commit cycle and merge happens once in a while. Old_Branch was used as a parent for New_Branch

Old_Branch was updated with some changes which required to be merged with New_Branch

Was using below pull command without any branch to get all sources from all branches.

git pull origin

Strangely this doesn't pull all the commits from all the branches. Had thought it so as the indicated shows almost all branches and tags.

So to fix this had checked out the Old_Branch pulled the latest using

git checkout Old_Branch

git pull origin Old_Branch

Now checked out New_Branch

git checkout New_Branch

Pulled it to be sure

git pull origin New_Branch

git merge Old_Branch

And viola got conflicts to fix from Old_Branch to New_Branch :) which was expected

Of course AJAX is the solution,

To perform an AJAX request (for easiness we can use jQuery library).

Step1.

Include jQuery library in your web page

a. you can download jQuery library from jquery.com and keep it locally.

b. or simply paste the following code,

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>

Step 2.

Call a javascript function on button click

<button type="button" onclick="foo()">Click Me</button>

Step 3.

and finally the function

 function foo () {
      $.ajax({
        url:"test.php", //the page containing php script
        type: "POST", //request type
        success:function(result){
         alert(result);
       }
     });
 }

it will make an AJAX request to test.php when ever you clicks the button and alert the response.

For example your code in test.php is,

<?php echo 'hello'; ?>

then it will alert "hello" when ever you clicks the button.

        if (connectionInfo != null && !TextUtils.isEmpty(connectionInfo.ssid)) {
            Log.e("ssid", connectionInfo.ssid)
        }
    }
    else{
        Log.e("ssid", "No Connection")
    }

}

Both lines have the same problem

T newT1 = "some text";
T newT2 = (string)t;

The compiler doesn't know that T is a string and so has no way of knowing how to assign that. But since you checked you can just force it with

T newT1 = "some text" as T;
T newT2 = t; 

you don't need to cast the t since it's already a string, also need to add the constraint

where T : class

DECLARE #MyTempTable TABLE (SiteName varchar(50), BillingMonth varchar(10), Consumption float)

INSERT INTO #MyTempTable (SiteName, BillingMonth, Consumption)
SELECT  tblMEP_Sites.Name AS SiteName, convert(varchar(10),BillingMonth ,101) AS BillingMonth, SUM(Consumption) AS Consumption
FROM tblMEP_Projects.......  --your joining statements

Here, # - use this to create table inside tempdb
@ - use this to create table as variable.

it is a little different in xcode 7.3.1. this is what i come up with

   // creating the view
        let newView = UIView()
        newView.backgroundColor = UIColor.redColor()
        newView.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(newView)

        // creating the constraint 

        // attribute and relation cannot be set directyl you need to create a cariable of them
        let layout11 = NSLayoutAttribute.CenterX
        let layout21 = NSLayoutRelation.Equal
        let layout31 = NSLayoutAttribute.CenterY
        let layout41 = NSLayoutAttribute.Width
        let layout51 = NSLayoutAttribute.Height
        let layout61 = NSLayoutAttribute.NotAnAttribute

        // defining all the constraint
        let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: layout11, relatedBy: layout21, toItem: view, attribute: layout11, multiplier: 1, constant: 0)
        let verticalConstraint = NSLayoutConstraint(item: newView, attribute: layout31, relatedBy: layout21, toItem: view, attribute: layout31, multiplier: 1, constant: 0)
        let widthConstraint = NSLayoutConstraint(item: newView, attribute: layout41, relatedBy: layout21, toItem: nil, attribute: layout61, multiplier: 1, constant: 100)
        let heightConstraint = NSLayoutConstraint(item: newView, attribute: layout51, relatedBy: layout21, toItem: nil, attribute: layout61, multiplier: 1, constant: 100)

        // adding all the constraint
        NSLayoutConstraint.activateConstraints([horizontalConstraint,verticalConstraint,widthConstraint,heightConstraint])

It is a code style convention; it indicates that a method returns a boolean value.

The question mark is a valid character at the end of a method name.

For using the FileOutputStream try this :

public class Main01{
    public static void main(String[] args) throws FileNotFoundException{
        FileOutputStream f = new FileOutputStream("file.txt");
        PrintStream p = new PrintStream(f);
        p.println("George.........");
        p.println("Alain..........");
        p.println("Gerard.........");
        p.close();
        f.close();
    }
}

I also banged my head around this problem for some time and wished to solve this in an elegant but quick way.

Here are my 20 cents:

• The answer using labels as mentioned here won't work if you are updating labels. But would work if you always add labels. More details here.

• The answer mentioned here is the most elegant way to do this quickly according to me but had the problem of handling deletes. I am adding on to this answer:

Solution

I am doing this in one of the Kubernetes Operator where only a single task is performed in one reconcilation loop.

• Compute the hash of the config map data. Say it comes as v2.
• Create ConfigMap cm-v2 having labels: version: v2 and product: prime if it does not exist and RETURN. If it exists GO BELOW.
• Find all the Deployments which have the label product: prime but do not have version: v2, If such deployments are found, DELETE them and RETURN. ELSE GO BELOW.
• Delete all ConfigMap which has the label product: prime but does not have version: v2 ELSE GO BELOW.
• Create Deployment deployment-v2 with labels product: prime and version: v2 and having config map attached as cm-v2 and RETURN, ELSE Do nothing.

That's it! It looks long, but this could be the fastest implementation and is in principle with treating infrastructure as Cattle (immutability).

Also, the above solution works when your Kubernetes Deployment has Recreate update strategy. Logic may require little tweaks for other scenarios.

For this you can use limit

select *
from scores
order by score desc
limit 10

If performance is important (when is it not ;-) look for an index on score.

Starting with version 8.4, you can also use the standard (SQL:2008) fetch first

select *
from scores
order by score desc
fetch first 10 rows only

As @Raphvanns pointed out, this will give you the first 10 rows literally. To remove duplicate values, you have to select distinct rows, e.g.

select distinct *
from scores
order by score desc
fetch first 10 rows only

SQL Fiddle

To assign value to a single Form control/individually, I propose to use setValue in the following way:

this.editqueForm.get('user').setValue(this.question.user);

this.editqueForm.get('questioning').setValue(this.question.questioning);

I would also add a canonical link to help your SEO people:

<link rel="canonical" href="http://www.example.com/product.php?item=swedish-fish"/>

Phonegap is pretty slow: clicking a button can take up to 3 sec to display the next screen. iscroll is slow and jumpy.

There other funny bugs and issues that i was able to overcome, but in total - not fully matured.

EDIT: Per Grumpy comment, it is not Phonegap who is actually slow, it is the JS/Browser native engine

dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))

na.omit(dat)
  x1  x2
1  1 100
3  3 300
5  5 500

Use this regular expression to match square brackets or single quotes:

/[\[\]']+/g

Replace with the empty string.

console.log("['abc','xyz']".replace(/[\[\]']+/g,''));

The actual problem is not IE8, but the hacks that you use for earlier versions of IE.

IE8 is pretty close to be standards compliant, so you shouldn't need any hacks at all for it, perhaps only some tweaks. The problem is if you are using some hacks for IE6 and IE7; you will have to make sure that they only apply to those versions and not IE8.

I made the web site of our company compatible with IE8 a while ago. The only thing that I actually changed was adding the meta tag that tells IE that the pages are IE8 compliant...

This should work for you:

Dim oShell
Dim iValue

Set oShell = CreateObject("WScript.Shell")

iValue = oShell.RegRead("HKLM\SOFTWARE\SOMETHINGSOMETHING")

If you want a "editable grid" i.e. a table like structure that allows you to make any of the rows a form, use CSS that mimics the TABLE tag's layout: display:table, display:table-row, and display:table-cell.

There is no need to wrap your whole table in a form and no need to create a separate form and table for each apparent row of your table.

Try this instead:

<style>
DIV.table 
{
    display:table;
}
FORM.tr, DIV.tr
{
    display:table-row;
}
SPAN.td
{
    display:table-cell;
}
</style>
...
<div class="table">
    <form class="tr" method="post" action="blah.html">
        <span class="td"><input type="text"/></span>
        <span class="td"><input type="text"/></span>
    </form>
    <div class="tr">
        <span class="td">(cell data)</span>
        <span class="td">(cell data)</span>
    </div>
    ...
</div>

The problem with wrapping the whole TABLE in a FORM is that any and all form elements will be sent on submit (maybe that is desired but probably not). This method allows you to define a form for each "row" and send only that row of data on submit.

The problem with wrapping a FORM tag around a TR tag (or TR around a FORM) is that it's invalid HTML. The FORM will still allow submit as usual but at this point the DOM is broken. Note: Try getting the child elements of your FORM or TR with JavaScript, it can lead to unexpected results.

Note that IE7 doesn't support these CSS table styles and IE8 will need a doctype declaration to get it into "standards" mode: (try this one or something equivalent)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Any other browser that supports display:table, display:table-row and display:table-cell should display your css data table the same as it would if you were using the TABLE, TR and TD tags. Most of them do.

Note that you can also mimic THEAD, TBODY, TFOOT by wrapping your row groups in another DIV with display: table-header-group, table-row-group and table-footer-group respectively.

NOTE: The only thing you cannot do with this method is colspan.

I saw the Selected Answer by Nathan Strutz, however, the jQuery Plugin page link is still down and the home page for that site did not seem to load. I tried a few other solutions and found most of them to be, not only out-dated, but EASY! Thus I threw my hat out there and made my own plugin, and with the dead links here, this seems like a great place to submit an answer. If you're looking for this answer in 2012 (soon to b 2013) you may notice the frustration of dead links and old advice here as I did. Below is a link to my modern plugin example as well as the code to the plugin! Simply copy the code into a JS file & link it in your header like any other plugin. Use is EXTREMELY EZ!

For a lot of projects, there is actually 0% difference between the different pythons in terms of speed. That is those that are dominated by engineering time and where all pythons have the same amount of library support.

For me it worked using flexbox, which is in my opinion the cleanest solution.

Add a css class around the parent div / element with :

.parent {
display: flex;
}

and for the button use:

.button {
justify-content: center;
}

You should use a parent div, otherwise the button doesn't 'know' what the middle of the page / element is.

If this is not working, try :

#wrapper {
    display:flex;
    justify-content: center;
}

If it happens that you need the Current Active Form from your MDI application: (MDI- Multi Document Interface).

Form activForm;
activForm = Form.ActiveForm.ActiveMdiChild;

The | and & check both the sides everytime.

if (str == null | str.length() == 0)

here we have high possibility to get NullPointerException

Logical || and && check the right hand side only if necessary.

but with logical operator

no chance to get NPE because it will not check RHS

I answered this question on another SO question before deciding to also include my answer as an answer on this thread, because no one was addressing how to require/not require items, just handing out regexs: Regex working wrong, matching unexpected things

From my post on that site, I've created a quick guide to assist anyone with making their own regex for their own desired phone number format, which I will caveat (like I did on the other site) that if you are too restrictive, you may not get the desired results, and there is no "one size fits all" solution to accepting all possible phone numbers in the world - only what you decide to accept as your format of choice. Use at your own risk.

Quick cheat sheet

• Start the expression: /^
• If you want to require a space, use: [\s] or \s
• If you want to require parenthesis, use: [(] and [)] . Using \( and \) is ugly and can make things confusing.
• If you want anything to be optional, put a ? after it
• If you want a hyphen, just type - or [-] . If you do not put it first or last in a series of other characters, though, you may need to escape it: \-
• If you want to accept different choices in a slot, put brackets around the options: [-.\s] will require a hyphen, period, or space. A question mark after the last bracket will make all of those optional for that slot.
• \d{3} : Requires a 3-digit number: 000-999. Shorthand for [0-9][0-9][0-9].
• [2-9] : Requires a digit 2-9 for that slot.
• (\+|1\s)? : Accept a "plus" or a 1 and a space (pipe character, |, is "or"), and make it optional. The "plus" sign must be escaped.
• If you want specific numbers to match a slot, enter them: [246] will require a 2, 4, or 6. (?:77|78) or [77|78] will require 77 or 78.
• $/ : End the expression

You can use WebClient to download the html for any url. Once you have the html, you can use a third-party library like HtmlAgilityPack to lookup values in the html as in below code -

public static string GetInnerHtmlFromDiv(string url)
    {
        string HTML;
        using (var wc = new WebClient())
        {
            HTML = wc.DownloadString(url);
        }
        var doc = new HtmlAgilityPack.HtmlDocument();
        doc.LoadHtml(HTML);
        
        HtmlNode element = doc.DocumentNode.SelectSingleNode("//div[@id='<div id here>']");
        if (element != null)
        {
            return element.InnerHtml.ToString();
        }   
        return null;            
    }

You are doing it right, so I guess something else is at fault (not export-ing COLUMNS ?).

A trick to debug these cases is to make a specialized command (a closure for programming language guys). Create a shell script named diff-columns doing:

exec /usr/bin/diff -x -y -w -p -W "$COLUMNS" "$@"

and just use

svn diff "$@" --diff-cmd  diff-columns

This way your code is cleaner to read and more modular (top-down approach), and you can test the diff-columns code thouroughly separately (bottom-up approach).

Put all the divs in a individual table cells and set the table style to padding: 5px;.

E.g.

<table style="width: 100%; padding: 5px;">_x000D_
<tbody>_x000D_
<tr>_x000D_
<td>_x000D_
<div style="background-color: red;">A</div>_x000D_
</td>_x000D_
<td>_x000D_
<div style="background-color: orange;">B</div>_x000D_
</td>_x000D_
<td>_x000D_
<div style="background-color: green;">C</div>_x000D_
</td>_x000D_
<td>_x000D_
<div style="background-color: blue;">D</div>_x000D_
</td>_x000D_
</tr>_x000D_
</tbody>_x000D_
</table>

here's the semantic of break:

int[] a = new int[] { 1, 3, 4, 6, 7, 9, 10 };
// find 9
for(int i = 0; i < a.Length; i++)
{
    if (a[i] == 9) 
        goto goBreak;

    Console.WriteLine(a[i].ToString());      
}
goBreak:;

here's the semantic of continue:

int[] a = new int[] { 1, 3, 4, 6, 7, 9, 10 };
// skip all odds
for(int i = 0; i < a.Length; i++)
{
    if (a[i] % 2 == 1) 
        goto goContinue;

    Console.WriteLine(a[i].ToString());      

goContinue:;
}

Dictionary< TKey, TValue > It is a generic collection class in c# and it stores the data in the key value format.Key must be unique and it can not be null whereas value can be duplicate and null.As each item in the dictionary is treated as KeyValuePair< TKey, TValue > structure representing a key and its value. and hence we should take the element type KeyValuePair< TKey, TValue> during the iteration of element.Below is the example.

Dictionary<int, string> dict = new Dictionary<int, string>();
dict.Add(1,"One");
dict.Add(2,"Two");
dict.Add(3,"Three");

foreach (KeyValuePair<int, string> item in dict)
{
    Console.WriteLine("Key: {0}, Value: {1}", item.Key, item.Value);
}

The listings package is quite nice and very flexible (e.g. different sizes for comments and code).

I realize you needed a solution for IE6/7 but I'm just throwing this out for anyone else.

If you can't use table-layout: fixed and you don't care about IE < 9 this works for all browsers.

td {
    overflow-x: hidden;
    overflow-y: hidden;
    white-space: nowrap;
    max-width: 30px;
}

I use MongoVUE, it's good for viewing data, but there is almost no editing abilities.

You can get the value of a file field just the same as any other field. You can't alter it, however.

So to superficially check if a file has the right extension, you could do something like this:

var ext = $('#my_file_field').val().split('.').pop().toLowerCase();
if($.inArray(ext, ['gif','png','jpg','jpeg']) == -1) {
    alert('invalid extension!');
}

If you want to generate a random float in a range, try a next solution.

#include <stdio.h>
#include <stdlib.h>
#include <time.h>


float
random_float(const float min, const float max)
{
    if (max == min) return min;
    else if (min < max) return (max - min) * ((float)rand() / RAND_MAX) + min;

    // return 0 if min > max
    return 0;
}


int
main (const int argc, const char *argv[])
{
    srand(time(NULL));

    char line[] = "-------------------------------------------";

    float data[10][2] = {
        {-10, 10},
        {-5., 5},
        {-1, 1},
        {-0.25, -0.15},
        {1.5, 1.52},
        {-1700, 8000},
        {-0.1, 0.1},
        {-1, 0},
        {-1, -2},
        {1.2, 1.1}
    };

    puts(line);
    puts("     From    |    Result    |      To");
    puts(line);


    int i;
    for (i = 0; i < 10; ++i) {
        printf("%12f | %12f | %12f\n", data[i][0], random_float(data[i][0], data[i][1]), data[i][1]);
    }

    puts(line);

    return 0;
}

A result (values is fickle)

Using session, I successfully passed a parameter (name) from servlet #1 to servlet #2, using response.sendRedirect in servlet #1. Servlet #1 code:

protected void doPost(HttpServletRequest request, HttpServletResponse response) {
    String name = request.getParameter("name");
    String password = request.getParameter("password");
    ...
    request.getSession().setAttribute("name", name);
    response.sendRedirect("/todo.do");

In Servlet #2, you don't need to get name back. It's already connected to the session. You could do String name = (String) request.getSession().getAttribute("name"); ---but you don't need this.

If Servlet #2 calls a JSP, you can show name this way on the JSP webpage:

<h1>Welcome ${name}</h1>

This was my quick-and-dirty solution. Note that it will have unexpected results if the input text has characters that are forbidden in file names.

@echo off
set /p input=Enter some text with spaces before and after^>
echo "%input%"
for /f "tokens=*" %%i in ('echo %input%') do set trimmed=%%~nxi
echo "%trimmed%"

EDIT

To provide a more robust text input character set and still remove the single trailing space that would normally be left by the for in ('echo...') approach, this is an alternative:

set /p input=Enter some text with spaces before and after^>
for /f "tokens=*" %%i in ('echo %input%') do set j=%%i
set trimmed=%j:~0,-1%
echo "%trimmed%"

Updated answer for ES6+ is here.

arr = [1, 2, 3]; 

arr.forEach(function(i, idx, array){
   if (idx === array.length - 1){ 
       console.log("Last callback call at index " + idx + " with value " + i ); 
   }
});

would output:

Last callback call at index 2 with value 3

The way this works is testing arr.length against the current index of the array, passed to the callback function.

I was also confused about them. See this example below:

<Window x:Class="WpfApplicationWPF.CommandsWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="CommandsWindow" Height="300" Width="300">

    <StackPanel>
        <Button Name="ButtonNew" 
                Click="ButtonNew_Click" 
                Background="{DynamicResource PinkBrush}">NEW</Button>
        <Image Name="ImageNew" 
               Source="pack://application:,,,/images/winter.jpg"></Image>
    </StackPanel>


    <Window.Background>
        <DynamicResource ResourceKey="PinkBrush"></DynamicResource>
    </Window.Background>

</Window>

Here I have used dynamic resource for button and window and have not declared it anywhere.Upon runtime, the ResourceDictionary of the hierarchy will be checked.Since I have not defined it, I guess the default will be used.

If I add the code below to click event of Button, since they use DynamicResource, the background will be updated accordingly.

private void ButtonNew_Click(object sender, RoutedEventArgs e)
{
    this.Resources.Add(  "PinkBrush"
                         ,new SolidColorBrush(SystemColors.DesktopColor)
                       );
}

If they had used StaticResource:

• The resource has to be declared in XAML
• And that too "before" they are used.

Hope I cleared some confusion.

When you call document.write after a page has loaded it will eliminate all content and replace it with the parameter you provide. Instead use DOM methods to add content, for example:

var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
var text = document.createTextNode('hi');
OpenWindow.document.body.appendChild(text);

If you want to use jQuery you get some better APIs to deal with. For example:

var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
$(OpenWindow.document.body).append('<p>hi</p>');

If you need the code to run after the new window's DOM is ready try:

var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
$(OpenWindow.document.body).ready(function() {
    $(OpenWindow.document.body).append('<p>hi</p>');
});

UPDATE table1 SET col_a = 'newvalue'

Add a WHERE condition if you want to only update some of the rows.

You don't escape quotes in regular expressions

this.Vals.replace(/["']/g, "")

[100 %]Solved. I had the same problem today. I checked my server space

df-h

I saw that server is out of space so i check which directory has most size by

sudo du -ch / | sort -h

I saw 12.2G /var/lib/jenkins so i entered this folder and cleared all the logs by

cd /var/libs/jenkins
rm *

and restart the jenkins it will work normal

sudo systemctl restart jenkins.service

You can also try this:

EditText searchTo = (EditText)findViewById(R.id.medittext);
searchTo.addTextChangedListener(new TextWatcher() {
    @Override
    public void afterTextChanged(Editable s) {
        // TODO Auto-generated method stub
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        // TODO Auto-generated method stub
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        doSomething();
    } 
});

If you have only 1 object like the one you asked, the following will work.

var x = [{'a':'b'}];
var b= JSON.stringify(x);
var c = b.substring(1,b.length-1);
JSON.parse(c); 

I recently felt like I had to do this too, but then found another way which possibly makes my code look neater, and uses better OOP.

I have many sibling classes that each implement a certain method doSomething(). In order to access that method, I would have to have an instance of that class first, but I created a superclass for all my sibling classes and now I can access the method from the superclass.

Below I show two ways alternative ways to "dynamic casting".

// Method 1.
mFragment = getFragmentManager().findFragmentByTag(MyHelper.getName(mUnitNum));
switch (mUnitNum) {
case 0:
    ((MyFragment0) mFragment).sortNames(sortOptionNum);
    break;
case 1:
    ((MyFragment1) mFragment).sortNames(sortOptionNum);
    break;
case 2:
    ((MyFragment2) mFragment).sortNames(sortOptionNum);
    break;
}

and my currently used method,

// Method 2.
mSuperFragment = (MySuperFragment) getFragmentManager().findFragmentByTag(MyHelper.getName(mUnitNum));
mSuperFragment.sortNames(sortOptionNum);

The list of valid characters is in the XML specification:

Char       ::=      #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]  /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */

Do you really need an object? What about:

$myArray[] = array("name" => "my name");

Just use a two-dimensional array.

Output (var_dump):

array(1) {
  [0]=>
  array(1) {
    ["name"]=>
    string(7) "my name"
  }
}

You could access your last entry like this:

echo $myArray[count($myArray) - 1]["name"];

with itertools.product:

import itertools
result = list(itertools.product(*somelists))

You need to set permissions within SSRS in two places to give yourself initial access. The set-up program only gives access to Builtin\Administrators, to gain access in order to do this you need to right click you browser link and choose Run as administrator.

1. Run internet explorer as Administrator
2. Open the report Manager URL, this time you should get in
3. Go to Site Settings in the top right
4. Click Security then New Role Assignment
5. Enter your domain\username and select System Administrator, click ok
6. Add other users as necessary
7. Click home, Folder Settings, then New Role Assignment
8. Enter your domain\username and select Content Manager, click ok
9. Add other users as necessary
10. Re-open internet explorer (non-admin) and recheck the url.

SearchTools-Avi said "MySQL text search, which doesn't even index words of three letters or fewer."

FYIs, The MySQL fulltext min word length is adjustable since at least MySQL 5.0. Google 'mysql fulltext min length' for simple instructions.

That said, MySQL fulltext has limitations: for one, it gets slow to update once you reach a million records or so, ...

IMO it's the different way to resolve a name from the OS and PHP.

Try:

echo gethostbyname("host.name.tld");

and

var_export (dns_get_record ( "host.name.tld") );

or

$dns=array("8.8.8.8","8.8.4.4");
var_export (dns_get_record ( "host.name.tld" ,  DNS_ALL , $dns ));

You should found some DNS/resolver error.

The part about not being able to use the Back button is a common misinterpretation. window.location.replace(URL) throws out the top ONE entry from the page history list, by overwriting it with the new entry, so the user can't easily go Back to that ONE particular webpage. The function does NOT wipe out the entire page history list, nor does it make the Back button completely non-functional.

(NO function nor combination of parameters that I know of can change or overwrite history list entries that you don't own absolutely for certain - browsers generally impelement this security limitation by simply not even defining any operation that might at all affect any entry other than the top one in the page history list. I shudder to think what sorts of dastardly things malware might do if such a function existed.)

If you really want to make the Back button non-functional (probably not "user friendly": think again if that's really what you want to do), "open" a brand new window. (You can "open" a popup that doesn't even have a "Back" button too ...but popups aren't very popular these days:-) If you want to keep your page showing no matter what the user does (again the "user friendliness" is questionable), set up a window.onunload handler that just reloads your page all over again clear from the very beginning every time.

Another option:

sort file1 file2 | uniq -u > file3

If you want to see just the duplicate entries use "uniq -d" option:

sort file1 file2 | uniq -d > file3

string Output = Regex.Replace(Input, @"([ a-zA-Z0-9&, _]|^\s)", "");

Here all the special characters except space, comma, and ampersand are replaced. You can also omit space, comma and ampersand by the following regular expression.

string Output = Regex.Replace(Input, @"([ a-zA-Z0-9_]|^\s)", "");

Where Input is the string which we need to replace the characters.

All you need to version update of Node.js:

$ brew install node

If you don't have Homebrew; please go http://brew.sh/.

with open('writing_file.json', 'w') as w:
    with open('reading_file.json', 'r') as r:

            if 'hours' in element:
                del element['hours']
            w.write(json.dumps(element))

this is the method i use..

You're approaching this the wrong way. Just test your functionality: if an exception is thrown the test will automatically fail. If no exception is thrown, your tests will all turn up green.

I have noticed this question garners interest from time to time so I'll expand a little.

Background to unit testing

When you're unit testing it's important to define to yourself what you consider a unit of work. Basically: an extraction of your codebase that may or may not include multiple methods or classes that represents a single piece of functionality.

Or, as defined in The art of Unit Testing, 2nd Edition by Roy Osherove, page 11:

A unit test is an automated piece of code that invokes the unit of work being tested, and then checks some assumptions about a single end result of that unit. A unit test is almost always written using a unit testing framework. It can be written easily and runs quickly. It's trustworthy, readable, and maintainable. It's consistent in its results as long as production code hasn't changed.

What is important to realize is that one unit of work usually isn't just one method but at the very basic level it is one method and after that it is encapsulated by other unit of works.

Ideally you should have a test method for each separate unit of work so you can always immediately view where things are going wrong. In this example there is a basic method called getUserById() which will return a user and there is a total of 3 unit of works.

The first unit of work should test whether or not a valid user is being returned in the case of valid and invalid input.
Any exceptions that are being thrown by the datasource have to be handled here: if no user is present there should be a test that demonstrates that an exception is thrown when the user can't be found. A sample of this could be the IllegalArgumentException which is caught with the @Test(expected = IllegalArgumentException.class) annotation.

Once you have handled all your usecases for this basic unit of work, you move up a level. Here you do exactly the same, but you only handle the exceptions that come from the level right below the current one. This keeps your testing code well structured and allows you to quickly run through the architecture to find where things go wrong, instead of having to hop all over the place.

Handling a tests' valid and faulty input

At this point it should be clear how we're going to handle these exceptions. There are 2 types of input: valid input and faulty input (the input is valid in the strict sense, but it's not correct).

When you work with valid input you're setting the implicit expectancy that whatever test you write, will work.

Such a method call can look like this: existingUserById_ShouldReturn_UserObject. If this method fails (e.g.: an exception is thrown) then you know something went wrong and you can start digging.

By adding another test (nonExistingUserById_ShouldThrow_IllegalArgumentException) that uses the faulty input and expects an exception you can see whether your method does what it is supposed to do with wrong input.

TL;DR

You were trying to do two things in your test: check for valid and faulty input. By splitting this into two method that each do one thing, you will have much clearer tests and a much better overview of where things go wrong.

By keeping the layered unit of works in mind you can also reduce the amount of tests you need for a layer that is higher in the hierarchy because you don't have to account for every thing that might have gone wrong in the lower layers: the layers below the current one are a virtual guarantee that your dependencies work and if something goes wrong, it's in your current layer (assuming the lower layers don't throw any errors themselves).

You can use tree to generate something very similar to your example. Once you have the output, you can wrap it in a <pre> tag to preserve the plain text formatting.

For Python 3.x, use input(). For Python 2.x, use raw_input(). Don't forget you can add a prompt string in your input() call to create one less print statement. input("GUESS THAT NUMBER!").

Your format specifier is incorrect. From the printf() man page on my machine:

0 A zero '0' character indicating that zero-padding should be used rather than blank-padding. A '-' overrides a '0' if both are used;

Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);

Precision: An optional period, '.', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;

For your case, your format would be %09.3f:

#include <stdio.h>

int main(int argc, char **argv)
{
  printf("%09.3f\n", 4917.24);
  return 0;
}

Output:

$ make testapp
cc     testapp.c   -o testapp
$ ./testapp 
04917.240

Note that this answer is conditional on your embedded system having a printf() implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.

in your css:

.selected{
    background: #F00;
}

in the jquery:

$("#data tr").click(function(){
   $(this).toggleClass('selected');
});

Basically you create a class and adds/removes it from the selected row.

Btw you could have shown more effort, there's no css or jquery/js at all in your code xD

mvn spring-boot:run -Dspring-boot.run.profiles=foo,bar

**Source- **https://docs.spring.io/spring-boot/docs/current/maven-plugin/examples/run-profiles.html

Basically it is need when you multiple application-{environment}.properties is present inside in your project. by default, if you passed -Drun.profiles on command line or activeByDefault true in

 <profile>
    <id>dev</id>
    <properties>
        <activatedProperties>dev</activatedProperties>
    </properties>
    <activation>
        <activeByDefault>true</activeByDefault>
    </activation>
</profile>

Nothing defined like above it will choose by default application.properties otherwise you need to select by appending -Drun.profiles={dev/stage/prod}.

TL;DR

mvn spring-boot:run -Drun.profiles=dev

On Visual Studio 6.0

Alt+F9!!!

easy way to do it: To get the actual user count:

$ADInfo = Get-ADGroup -Identity '<groupname>' -Properties Members
$AdInfo.Members.Count

and you get the count easily, it is pretty fast as well for 20k+ users too

This error comes when there's incompatibility between node version and angular/cli version. therefore use below command to update the cli version to latest

npm install -g @angular/cli@latest

Make sure you have a block element, a maximum size and set overflow to hidden. (Tested in IE9 and FF 7)

http://jsfiddle.net/uh9zD/

div {
    border: solid 2px blue;
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
    width: 50px;
}

onChange will not call handleChange on mobile when using defaultChecked. As an alternative you can can use onClick and onTouchEnd.

<input onClick={this.handleChange} onTouchEnd={this.handleChange} type="checkbox" defaultChecked={!!this.state.complete} />;

This is an answer targeting primarily developers using Windows, as the path syntax of the diff tool differs from other platforms.

I use Kdiff3 as the git mergetool, but to set up the git difftool as Meld, I first installed the latest version of Meld from Meldmerge.org then added the following to my global .gitconfig using:

git config --global -e

Note, if you rather want Sublime Text 3 instead of the default Vim as core ditor, you can add this to the .gitconfig file:

[core]
editor = 'c:/Program Files/Sublime Text 3/sublime_text.exe'

Then you add inn Meld as the difftool

[diff]
tool = meld
guitool = meld 

[difftool "meld"]
cmd = \"C:/Program Files (x86)/Meld/Meld.exe\" \"$LOCAL\" \"$REMOTE\" --label \"DIFF 
(ORIGINAL MY)\"
prompt = false
path = C:\\Program Files (x86)\\Meld\\Meld.exe

Note the leading slash in the cmd above, on Windows it is necessary.

It is also possible to set up an alias to show the current git diff with a --dir-diff option. This will list the changed files inside Meld, which is handy when you have altered multiple files (a very common scenario indeed).

The alias looks like this inside the .gitconfig file, beneath [alias] section:

showchanges = difftool --dir-diff

To show the changes I have made to the code I then just enter the following command:

git showchanges

The following image shows how this --dir-diff option can show a listing of changed files (example):

Then it is possible to click on each file and show the changes inside Meld.

you can use:

Stopwatch.GetTimestamp();

Angular 4+

I've created a generic directive, able to receive any mask and also able to define the mask dynamically based on the value:

mask.directive.ts:

import { Directive, EventEmitter, HostListener, Input, Output } from '@angular/core';
import { NgControl } from '@angular/forms';

import { MaskGenerator } from '../interfaces/mask-generator.interface';

@Directive({

        [MaskDirective.NUMERIC, /\d/],
        [MaskDirective.ALPHANUMERIC, /\w|\d/],
    ]);

    private value: string = null;
    private displayValue: string = null;

    @Input('spMask') 
    public maskGenerator: MaskGenerator;

    @Input('spKeepMask') 
    public keepMask: boolean;

    @Input('spMaskValue') 
    public set maskValue(value: string) {
        if (value !== this.value) {
            this.value = value;
            this.defineValue();
        }
    };

    @Output('spMaskValueChange') 
    public changeEmitter = new EventEmitter<string>();

    @HostListener('input', ['$event'])
    public onInput(event: { target: { value?: string }}): void {
        let target = event.target;
        let value = target.value;
        this.onValueChange(value);
    }

    constructor(private ngControl: NgControl) { }

    private updateValue(value: string) {

        MaskDirective.delay().then(

    }

            let displayValue = newValue;
            let value = newValue;

            if ((newValue == null) || (newValue.trim() === '')) {
                value = null;
            } else if (this.maskGenerator) {
                let mask = this.maskGenerator.generateMask(newValue);
                displayValue = MaskDirective.mask(newValue, mask);
                value = MaskDirective.processValue(displayValue, mask, this.keepMask);
            }

            this.displayValue = displayValue;

            if (newValue !== displayValue) {
                this.ngControl.control.setValue(displayValue);
            }

            if (value !== this.value) {
                this.updateValue(value);
            }
        }
    }

    private static processValue(displayValue: string, mask: string, keepMask: boolean) {
        let value = keepMask ? displayValue : MaskDirective.unmask(displayValue, mask);
        return value
    }

    private static mask(value: string, mask: string): string {
        value = value.toString();

        let len = value.length;
        let maskLen = mask.length;
        let pos = 0;
        let newValue = '';

        for (let i = 0; i < Math.min(len, maskLen); i++) {
            let maskChar = mask.charAt(i);
            let newChar = value.charAt(pos);
            let regex: RegExp = MaskDirective.REGEX_MAP.get(maskChar);

            if (regex) {
                pos++;

                if (regex.test(newChar)) {
                    newValue += newChar;
                } else {
                    i--;
                    len--;
                }
            } else {
                if (maskChar === newChar) {
                    pos++;
                } else {

    }

    private static delay(ms: number = 0): Promise<void> {
        return new Promise(resolve => setTimeout(() => resolve(), ms)).then(() => null);
    }
}

(Remember to declare it in your NgModule)

The numeric character in the mask is 9 so your mask would be (999) 999-9999. You can change the NUMERIC static field if you want (if you change it to 0, your mask should be (000) 000-0000, for example).

The value is displayed with mask but stored in the component field without mask (this is the desirable behaviour in my case). You can make it be stored with mask using [spKeepMask]="true".

The directive receives an object that implements the MaskGenerator interface.

mask-generator.interface.ts:

export interface MaskGenerator {
    generateMask: (value: string) => string;
}

This way it's possible to define the mask dynamically based on the value (like credit cards).

I've created an utilitarian class to store the masks, but you can specify it directly in your component too.

my-mask.util.ts:

export class MyMaskUtil {

    private static PHONE_SMALL = '(999) 999-9999';
    private static PHONE_BIG = '(999) 9999-9999';
    private static CPF = '999.999.999-99';
    private static CNPJ = '99.999.999/9999-99';

    public static PHONE_MASK_GENERATOR: MaskGenerator = {
        generateMask: () =>  MyMaskUtil.PHONE_SMALL,
    }

    public static DYNAMIC_PHONE_MASK_GENERATOR: MaskGenerator = {
        generateMask: (value: string) => {
            return MyMaskUtil.hasMoreDigits(value, MyMaskUtil.PHONE_SMALL) ? 
                MyMaskUtil.PHONE_BIG : 
                MyMaskUtil.PHONE_SMALL;
        },
    }

    public static CPF_MASK_GENERATOR: MaskGenerator = {
        generateMask: () => MyMaskUtil.CPF,
    }

    public static CNPJ_MASK_GENERATOR: MaskGenerator = {
        generateMask: () => MyMaskUtil.CNPJ,
    }

    public static PERSON_MASK_GENERATOR: MaskGenerator = {
        generateMask: (value: string) => {
            return MyMaskUtil.hasMoreDigits(value, MyMaskUtil.CPF) ? 
                MyMaskUtil.CNPJ : 
                MyMaskUtil.CPF;
        },
    }

    private static hasMoreDigits(v01: string, v02: string): boolean {
        let d01 = this.onlyDigits(v01);
        let d02 = this.onlyDigits(v02);
        let len01 = (d01 && d01.length) || 0;
        let len02 = (d02 && d02.length) || 0;
        let moreDigits = (len01 > len02);
        return moreDigits;      
    }

    private static onlyDigits(value: string): string {
        let onlyDigits = (value != null) ? value.replace(/\D/g, '') : null;
        return onlyDigits;      
    }
}

Then you can use it in your component (use spMaskValue instead of ngModel, but if is not a reactive form, use ngModel with nothing, like in the example below, just so that you won't receive an error of no provider because of the injected NgControl in the directive; in reactive forms you don't need to include ngModel):

my.component.ts:

@Component({ ... })
export class MyComponent {
    public phoneValue01: string = '1231234567';
    public phoneValue02: string;
    public phoneMask01 = MyMaskUtil.PHONE_MASK_GENERATOR;
    public phoneMask02 = MyMaskUtil.DYNAMIC_PHONE_MASK_GENERATOR;
}

my.component.html:

<span>Phone 01 ({{ phoneValue01 }}):</span><br>
<input type="text" [(spMaskValue)]="phoneValue01" [spMask]="phoneMask01" ngModel>
<br><br>
<span>Phone 02 ({{ phoneValue02 }}):</span><br>
<input type="text" [(spMaskValue)]="phoneValue02" [spMask]="phoneMask02" [spKeepMask]="true" ngModel>

(Take a look at phone02 and see that when you type 1 more digit, the mask changes; also, look that the value stored of phone01 is without mask)

I've tested it with normal inputs as well as with ionic inputs (ion-input), with both reactive (with formControlName, not with formControl) and non-reactive forms.

Show all stashes

File names only:

for i in $(git stash list --format="%gd") ; do echo "======$i======"; git stash show $i; done

Full file contents in all stashes:

for i in $(git stash list --format="%gd") ; do echo "======$i======"; git stash show -p $i; done

You will get colorized diff output that you can page with space (forward) and b (backwards), and q to close the pager for the current stash. If you would rather have it in a file then append > stashes.diff to the command.

The easiest way I found, summarized in a few pictures:

You could skip a few steps (up to step 4) by simply navigating to chrome://settings/languages right away.

In jQuery you can do like this.

function random_no(){_x000D_
     var ran=Math.random();_x000D_
     jQuery('#random_no_container').html(ran);_x000D_
}_x000D_
           _x000D_
window.setInterval(function(){_x000D_
       /// call your function here_x000D_
      random_no();_x000D_
}, 6000);  // Change Interval here to test. For eg: 5000 for 5 sec

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="random_no_container">_x000D_
      Hello. Here you can see random numbers after every 6 sec_x000D_
</div>

Warnings

I would suggest very strongly against modifying the system Python on Mac; there are numerous issues that can occur.

Your particular error shows that the installer has issues resolving the dependencies for Scrapy without impacting the current Python installation. The system uses Python for a number of essential tasks, so it's important to keep the system installation stable and as originally installed by Apple.

I would also exhaust all other possibilities before bypassing built in security.

Package Manager Solutions:

Please look into a Python virtualization tool such as virtualenv first; this will allow you to experiment safely.

Another useful tool to use languages and software without conflicting with your Mac OS is Homebrew. Like MacPorts or Fink, Homebrew is a package manager for Mac, and is useful for safely trying lots of other languages and tools.

"Roll your own" Software Installs:

If you don't like the package manager approach, you could use the /usr/local path or create an /opt/local directory for installing an alternate Python installation and fix up your paths in your .bashrc. Note that you'll have to enable root for these solutions.

How to do it anyway:

If you absolutely must disable the security check (and I sincerely hope it's for something other than messing with the system languages and resources), you can disable it temporarily and re-enable it using some of the techniques in this post on how to Disable System Integrity-Protection.

We had a situation where IE forced us to post as text/plain, so we had to manually parse the parameters using getReader. The servlet was being used for long polling, so when AsyncContext::dispatch was executed after a delay, it was literally reposting the request empty handed.

So I just stored the post in the request when it first appeared by using HttpServletRequest::setAttribute. The getReader method empties the buffer, where getParameter empties the buffer too but stores the parameters automagically.

    String input = null;

    // we have to store the string, which can only be read one time, because when the
    // servlet awakens an AsyncContext, it reposts the request and returns here empty handed
    if ((input = (String) request.getAttribute("com.xp.input")) == null) {
        StringBuilder buffer = new StringBuilder();
        BufferedReader reader = request.getReader();

        String line;
        while((line = reader.readLine()) != null){
            buffer.append(line);
        }
        // reqBytes = buffer.toString().getBytes();

        input = buffer.toString();
        request.setAttribute("com.xp.input", input);
    }

    if (input == null) {
        response.setContentType("text/plain");
        PrintWriter out = response.getWriter();
        out.print("{\"act\":\"fail\",\"msg\":\"invalid\"}");
    }       

import sys
userinput = sys.stdin.readline()
betAmount = int(userinput)

print betAmount

This works on my system. I checked int('23\n') would result in 23.

You can't add a Button to an empty list without creating a new instance of that Button. You are missing the

Button newButton = new Button();  

in your code plus get rid of the .Capacity

If your <option> elements don't have value attributes, then you can just use .val:

$selectElement.val("text_you're_looking_for")

However, if your <option> elements have value attributes, or might do in future, then this won't work, because whenever possible .val will select an option by its value attribute instead of by its text content. There's no built-in jQuery method that will select an option by its text content if the options have value attributes, so we'll have to add one ourselves with a simple plugin:

/*
  Source: https://stackoverflow.com/a/16887276/1709587

  Usage instructions:

  Call

      jQuery('#mySelectElement').selectOptionWithText('target_text');

  to select the <option> element from within #mySelectElement whose text content
  is 'target_text' (or do nothing if no such <option> element exists).
*/
jQuery.fn.selectOptionWithText = function selectOptionWithText(targetText) {
    return this.each(function () {
        var $selectElement, $options, $targetOption;

        $selectElement = jQuery(this);
        $options = $selectElement.find('option');
        $targetOption = $options.filter(
            function () {return jQuery(this).text() == targetText}
        );

        // We use `.prop` if it's available (which it should be for any jQuery
        // versions above and including 1.6), and fall back on `.attr` (which
        // was used for changing DOM properties in pre-1.6) otherwise.
        if ($targetOption.prop) {
            $targetOption.prop('selected', true);
        } 
        else {
            $targetOption.attr('selected', 'true');
        }
    });
}

Just include this plugin somewhere after you add jQuery onto the page, and then do

jQuery('#someSelectElement').selectOptionWithText('Some Target Text');

to select options.

The plugin method uses filter to pick out only the option matching the targetText, and selects it using either .attr or .prop, depending upon jQuery version (see .prop() vs .attr() for explanation).

Here's a JSFiddle you can use to play with all three answers given to this question, which demonstrates that this one is the only one to reliably work: http://jsfiddle.net/3cLm5/1/

One way to create a quick test query in Windows via an ODBC connection is using the DQY format.

To achieve this, create a DQY file (e.g. test.dqy) containing the magic first two lines (XLODBC and 1) as below, followed by your ODBC connection string on the third line and your query on the fourth line (all on one line), e.g.:

XLODBC
1
Driver={Microsoft ODBC for Oracle};server=DB;uid=scott;pwd=tiger;
SELECT COUNT(1) n FROM emp

Then, if you open the file by double-clicking it, it will open in Excel and populate the worksheet with the results of the query.

JavaScript only has a Number type that stores floating point values.

There is no int.

Edit:

If you want to format the number as a string with two digits after the decimal point use:

(4).toFixed(2)

The error message tells the exact reason: "abstract methods cannot have a body".

They can only be defined in abstract classes and interfaces (interface methods are implicitly abstract!) and the idea is, that the subclass implements the method.

Example:

 public abstract class AbstractGreeter {
   public abstract String getHelloMessage();

   public void sayHello() {
     System.out.println(getHelloMessage());
   }
 }

 public class FrenchGreeter extends AbstractGreeter{

   // we must implement the abstract method
   @Override
   public String getHelloMessage() {
     return "bonjour";
   }
 }

You could try something like this as well

<a href="#" onclick="one(); two();" >click</a>

<script type="text/javascript">
    function one(){
        alert('test');
    }

    function two(){
        alert('test2');
    }
</script>

For iterm2:

Go to Profiles / Open Profiles / Keys

Set Cmd + left_arrow_key to Send Hex Code 001

Set Cmd + right_arrow_key to Send Hex Code 005

This allows you to use Cmd + arrow_keys to move from beginning to end of the line.

Your question is: are these not modules capable of declaring variables at global scope?

Answer: YES, they are "capable"

The only point is that references to global variables in ThisWorkbook or a Sheet module have to be fully qualified (i.e., referred to as ThisWorkbook.Global1, e.g.) References to global variables in a standard module have to be fully qualified only in case of ambiguity (e.g., if there is more than one standard module defining a variable with name Global1, and you mean to use it in a third module).

For instance, place in Sheet1 code

Public glob_sh1 As String

Sub test_sh1()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

place in ThisWorkbook code

Public glob_this As String

Sub test_this()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

and in a Standard Module code

Public glob_mod As String

Sub test_mod()
    glob_mod = "glob_mod"
    ThisWorkbook.glob_this = "glob_this"
    Sheet1.glob_sh1 = "glob_sh1"
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

All three subs work fine.

PS1: This answer is based essentially on info from here. It is much worth reading (from the great Chip Pearson).

PS2: Your line Debug.Print ("Hello") will give you the compile error Invalid outside procedure.

PS3: You could (partly) check your code with Debug -> Compile VBAProject in the VB editor. All compile errors will pop.

PS4: Check also Put Excel-VBA code in module or sheet?.

PS5: You might be not able to declare a global variable in, say, Sheet1, and use it in code from other workbook (reading http://msdn.microsoft.com/en-us/library/office/gg264241%28v=office.15%29.aspx#sectionSection0; I did not test this point, so this issue is yet to be confirmed as such). But you do not mean to do that in your example, anyway.

PS6: There are several cases that lead to ambiguity in case of not fully qualifying global variables. You may tinker a little to find them. They are compile errors.

1.gcc version >= 5
2.CXXFLAGS += -std=c++14
3. #include <memory>

I will make my contribution here... why? just because :p Its a different implementation, based on the Any LINQ extension, and a delegate. Here it is:

public static class Extensions

    public static int IndexOf<T>(
            this IEnumerable<T> list, 
            Predicate<T> condition) {

In case of upgrading your python on mac os 10.7 and pkg_resources doesn't work, the simplest way to fix this is just reinstall setuptools as Ned mentioned above.

sudo pip install setuptools --upgrade
or sudo easy_install install setuptools --upgrade

I borrowed this method from underscore.js fiddler

window.helpers=(function (){
    var lookupIterator = function(value) {
        if (value == null){
            return function(value) {
                return value;
            };
        }
        if (typeof value === 'function'){
                return value;
        }

        if (Array.prototype.forEach && obj.forEach === Array.prototype.forEach) {
            obj.forEach(iterator, context);
        } else if (obj.length === +obj.length) {
            for (var i = 0, length = obj.length; i < length; i++) {
                if (iterator.call(context, obj[i], i, obj) === breaker) return;

    group = function(behavior) {

            });
            return result;

    };

    return {

Add this line before main function:

void swapCase (char* name);

int main()
{
   ...
   swapCase(name);    // swapCase prototype should be known at this point
   ...
}

This is called forward declaration: compiler needs to know function prototype when function call is compiled.

It is possible using ConfigTransform build target available as a Nuget package - https://www.nuget.org/packages/CodeAssassin.ConfigTransform/

All "web.*.config" transform files will be transformed and output as a series of "web.*.config.transformed" files in the build output directory regardless of the chosen build configuration.

The same applies to "app.*.config" transform files in non-web projects.

and then adding the following target to your *.csproj.

<Target Name="TransformActiveConfiguration" Condition="Exists('$(ProjectDir)/Web.$(Configuration).config')" BeforeTargets="Compile" >
    <TransformXml Source="$(ProjectDir)/Web.Config" Transform="$(ProjectDir)/Web.$(Configuration).config" Destination="$(TargetDir)/Web.config" />
</Target>

Posting an answer as this is the first Stackoverflow post that appears in Google on the subject.

I think a lookup table has to be one of the simplest methods. However, you don't need a full lookup table.

//Index 1==0b0001 => 0b1000
//Index 7==0b0111 => 0b1110
//etc
static unsigned char lookup[16] = {
0x0, 0x8, 0x4, 0xc, 0x2, 0xa, 0x6, 0xe,
0x1, 0x9, 0x5, 0xd, 0x3, 0xb, 0x7, 0xf, };

uint8_t reverse(uint8_t n) {
   // Reverse the top and bottom nibble then swap them.
   return (lookup[n&0b1111] << 4) | lookup[n>>4];
}

// Detailed breakdown of the math
//  + lookup reverse of bottom nibble
//  |       + grab bottom nibble
//  |       |        + move bottom result into top nibble
//  |       |        |     + combine the bottom and top results 
//  |       |        |     | + lookup reverse of top nibble
//  |       |        |     | |       + grab top nibble
//  V       V        V     V V       V
// (lookup[n&0b1111] << 4) | lookup[n>>4]

This fairly simple to code and verify visually.
Ultimately this might even be faster than a full table. The bit arith is cheap and the table easily fits on a cache line.

Change this:

sift = cv2.xfeatures2d.SIFT_create()

By this:

cv2.ORB_create()

Unless you have some kind of really weird problem, keep it. The number of IPv6 sites is very small, but there are some and it will let you get to them even if you're at an IPv4 only location.

If it is causing you a problem, it's best to fix it. I've seen a number of people recommending removing it to solve problems. However, they're not actually solving the root cause of the issue. In all the cases I've seen, removing Teredo just happens to cause a side-effect that fixes their problem... :)

Here's a way with gsub:

cs <- c("foo_bar","bar_foo","apple","beer")
gsub('.{3}$', '', cs)
# [1] "foo_" "bar_" "ap"   "b"

Here is the example of generic and the shortest version for function currying with n no. of params.

const add = a => b => b ? add(a + b) : a; 

const add = a => b => b ? add(a + b) : a; _x000D_
console.log(add(1)(2)(3)(4)());

Based on this questions answer I implemented a class you can use to read a file synchronously line-by-line with fs.readSync(). You can make this "pause" and "resume" by using a Q promise (jQuery seems to require a DOM so cant run it with nodejs):

var fs = require('fs');
var Q = require('q');

var lr = new LineReader(filenameToLoad);
lr.open();

var promise;
workOnLine = function () {
    var line = lr.readNextLine();
    promise = complexLineTransformation(line).then(
        function() {console.log('ok');workOnLine();},
        function() {console.log('error');}
    );
}
workOnLine();

complexLineTransformation = function (line) {
    var deferred = Q.defer();
    // ... async call goes here, in callback: deferred.resolve('done ok'); or deferred.reject(new Error(error));
    return deferred.promise;
}

function LineReader (filename) {      
  this.moreLinesAvailable = true;
  this.fd = undefined;
  this.bufferSize = 1024*1024;
  this.buffer = new Buffer(this.bufferSize);
  this.leftOver = '';

  this.read = undefined;
  this.idxStart = undefined;
  this.idx = undefined;

  this.lineNumber = 0;

  this._bundleOfLines = [];

  this.open = function() {
    this.fd = fs.openSync(filename, 'r');
  };

  this.readNextLine = function () {
    if (this._bundleOfLines.length === 0) {
      this._readNextBundleOfLines();
    }
    this.lineNumber++;
    var lineToReturn = this._bundleOfLines[0];
    this._bundleOfLines.splice(0, 1); // remove first element (pos, howmany)
    return lineToReturn;
  };

  this.getLineNumber = function() {
    return this.lineNumber;
  };

  this._readNextBundleOfLines = function() {
    var line = "";
    while ((this.read = fs.readSync(this.fd, this.buffer, 0, this.bufferSize, null)) !== 0) { // read next bytes until end of file
      this.leftOver += this.buffer.toString('utf8', 0, this.read); // append to leftOver
      this.idxStart = 0
      while ((this.idx = this.leftOver.indexOf("\n", this.idxStart)) !== -1) { // as long as there is a newline-char in leftOver
        line = this.leftOver.substring(this.idxStart, this.idx);
        this._bundleOfLines.push(line);        
        this.idxStart = this.idx + 1;
      }
      this.leftOver = this.leftOver.substring(this.idxStart);
      if (line !== "") {
        break;
      }
    }
  }; 
}

Personally I like to keep the label outside, like in your second example. That's why the FOR attribute is there. The reason being I'll often apply styles to the label, like a width, to get the form to look nice (shorthand below):

<style>
label {
  width: 120px;
  margin-right: 10px;
}
</style>

<label for="myinput">My Text</label>
<input type="text" id="myinput" /><br />
<label for="myinput2">My Text2</label>
<input type="text" id="myinput2" />

Makes it so I can avoid tables and all that junk in my forms.

you can just delete the Credential Manager.

C:\Users\<USER>\AppData\Local\Programs\Git\mingw64\libexec\git-core

As Ajay beniwal mentioned above you need to use Apply to start digestion.

var app = angular.module('test', []);

app.controller('TestCtrl', function ($scope) {
   $scope.testValue = 0;

    setInterval(function() {
        console.log($scope.testValue++);
        $scope.$apply() 
    }, 500);
});

Of course it is!

Give them both an id and set up the CSS accordingly:

#table1
{
    CSS for table1
}


#table2
{
    CSS for table2
}

I guess there are so many ways to make what you want. Here's a way that I use. With the commons.io library you can iterate over the files in a directory. You must use the FileUtils.iterateFiles method and you can process each file.

You can find the information here: http://commons.apache.org/proper/commons-io/download_io.cgi

Here's an example:

Iterator it = FileUtils.iterateFiles(new File("C:/"), null, false);
        while(it.hasNext()){
            System.out.println(((File) it.next()).getName());
        }

You can change null and put a list of extentions if you wanna filter. Example: {".xml",".java"}

I found some reasons for this exception.they are

1)The name of the database XE by default.so the url will be"jdbc:oracle:thin:@localhost:1521:XE".

2)Make sure that OracleServiceXE,OracleXETNSListener is running.it will be in Control Panel\All Control Panel Items\Administrative Tools\Services

Redirect stderr to stdout

This will redirect the stderr (which is descriptor 2) to the file descriptor 1 which is the the stdout.

2>&1

Redirect stdout to File

Now when perform this you are redirecting the stdout to the file sample.s

myprogram > sample.s

Redirect stderr and stdout to File

Combining the two commands will result in redirecting both stderr and stdout to sample.s

myprogram > sample.s 2>&1

Redirect stderr and stdout to /dev/null

Redirect to /dev/null if you want to completely silent your application.

myprogram >/dev/null 2>&1

Despite Daniel Böhmer's working solution, Ohad Schneider offered a better solution in a comment:

If the file is usually ignored, and you force adding it - it can be accidentally ignored again in the future (like when the file is deleted, then a commit is made and the file is re-created.

You should just un-ignore it in the .gitignore file like that: Unignore subdirectories of ignored directories in Git

With one feature my Dataframe list converts to a Series. I had to convert it back to a Dataframe list and it worked.

if type(X) is Series:
    X = X.to_frame()

mysql> CREATE USER 'name'@'%' IDENTIFIED BY 'passWord'; Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON . TO 'name'@'%'; Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.00 sec)

mysql>

1. Make sure you have your name and % the right way round
2. Makes sure you have added your port 3306 to any firewall you may be running (although this will give a different error message)

hope this helps someone...

There is also an .isInstance method on the "Class" class. if you get an object's class via myBanana.getClass() you can see if your object myApple is an instance of the same class as myBanana via

myBanana.getClass().isInstance(myApple)

You can do something like:

N <- 10
collect1 <- data.frame(id   = integer(N),
                       max1 = numeric(N),
                       min1 = numeric(N))

Now be careful that in the rest of your code, you forgot to use the row index for filling the data.frame row by row. It should be:

for(i in seq_len(N)){
   collect1$id[i] <- i
   ss1 <- subset(df1, df1$id == i)
   collect1$max1[i] <- max(ss1$value)
   collect1$min1[i] <- min(ss1$value)
}

Finally, I would say that there are many alternatives for doing what you are trying to accomplish, some would be much more efficient and use a lot less typing. You could for example look at the aggregate function, or ddply from the plyr package.

You are mixing mysqli and mysql function.

If your are using mysql function then instead mysqli_real_escape_string($your_variable); use

$username = mysql_real_escape_string($_POST['username']);
$pass = mysql_real_escape_string($_POST['pass']);
$pass1 = mysql_real_escape_string($_POST['pass1']);
$email = mysql_real_escape_string($_POST['email']);

If your using mysqli_* function then you have to include your connection to database into mysqli_real_escape function :

$username = mysqli_real_escape_string($your_connection, $_POST['username']);
$pass = mysqli_real_escape_string($your_connection, $_POST['pass']);
$pass1 = mysqli_real_escape_string($your_connection, $_POST['pass1']);
$email = mysqli_real_escape_string($your_connection, $_POST['email']);

Note : Use mysqli_* function since mysql has been deprecated. For information please read mysqli_*

Android SDK Build Tools are exactly what the name says they are; tools for building Android Applications.It is very important to use the latest build tools version (selected automatically by your IDE via the Android SDK) but the reason the old versions are left there is to support backward compatibility, that is If your projects depend on older versions of the Build Tools.

Just remember that modifying the padding or margins on any bootstrap grid elements is likely to create overflowing elements at some point at lower screen-widths.

If that happens just remember to use CSS media queries and only include the margins at screen-widths that can handle it.

In keeping with the mobile-first approach of the framework you are working within (bootstrap) it is better to add the padding at widths which can handle it, rather than excluding it at widths which can't.

@media (min-width: 992px){
    .navbar li {
        margin-left : 1em;
        margin-right : 1em;
    }
}

For passing an enum by intent, you can convert enum into integer.

Ex:

public enum Num{A ,B}

Sending(enum to integer):

Num send = Num.A;
intent.putExtra("TEST", send.ordinal());

Receiving(integer to enum):

Num rev;
int temp = intent.getIntExtra("TEST", -1);
if(temp >= 0 && temp < Num.values().length)
    rev = Num.values()[temp];

Best regards. :)

Match any single character

• Use the dot . character as a wildcard to match any single character.

Example regex: a.c

abc   // match
a c   // match
azc   // match
ac    // no match
abbc  // no match

Match any specific character in a set

• Use square brackets [] to match any characters in a set.
• Use \w to match any single alphanumeric character: 0-9, a-z, A-Z, and _ (underscore).
• Use \d to match any single digit.
• Use \s to match any single whitespace character.

Example 1 regex: a[bcd]c

abc   // match
acc   // match
adc   // match
ac    // no match
abbc  // no match

Example 2 regex: a[0-7]c

a0c   // match
a3c   // match
a7c   // match
a8c   // no match
ac    // no match
a55c  // no match

Match any character except ...

Use the hat in square brackets [^] to match any single character except for any of the characters that come after the hat ^.

Example regex: a[^abc]c

aac   // no match
abc   // no match
acc   // no match
a c   // match
azc   // match
ac    // no match
azzc  // no match

(Don't confuse the ^ here in [^] with its other usage as the start of line character: ^ = line start, $ = line end.)

Match any character optionally

Use the optional character ? after any character to specify zero or one occurrence of that character. Thus, you would use .? to match any single character optionally.

Example regex: a.?c

abc   // match
a c   // match
azc   // match
ac    // match
abbc  // no match

As the lines can be variable in logs I thought it best to take a number of lines per file approach. The following code snippet processed a 4 million line log file in under 19 seconds (18.83.. seconds)splitting it into 500,000 line chunks:

$sourceFile = "c:\myfolder\mylargeTextyFile.csv"
$partNumber = 1
$batchSize = 500000
$pathAndFilename = "c:\myfolder\mylargeTextyFile part $partNumber file.csv"

[System.Text.Encoding]$enc = [System.Text.Encoding]::GetEncoding(65001)  # utf8 this one

$fs=New-Object System.IO.FileStream ($sourceFile,"OpenOrCreate", "Read", "ReadWrite",8,"None") 
$streamIn=New-Object System.IO.StreamReader($fs, $enc)
$streamout = new-object System.IO.StreamWriter $pathAndFilename

$line = $streamIn.readline()
$counter = 0
while ($line -ne $null)
{
    $streamout.writeline($line)
    $counter +=1
    if ($counter -eq $batchsize)
    {
        $partNumber+=1
        $counter =0
        $streamOut.close()
        $pathAndFilename = "c:\myfolder\mylargeTextyFile part $partNumber file.csv"
        $streamout = new-object System.IO.StreamWriter $pathAndFilename

    }
    $line = $streamIn.readline()
}
$streamin.close()
$streamout.close()

This can easily be turned into a function or script file with parameters to make it more versatile. It uses a StreamReader and StreamWriter to achieve its speed and tiny memory footprint

The Regex Validator

So far, the other answers provide solutions for only a relatively finite number of digits. However, if you're concerned with an arbitrary or a variable number of digits you can use a QRegExpValidator, passing a regex that only accepts digits (as noted by user2962533's comment). Here's a minimal, complete example:

#include <QApplication>
#include <QLineEdit>
#include <QRegExpValidator>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QLineEdit le;
    le.setValidator(new QRegExpValidator(QRegExp("[0-9]*"), &le));
    le.show();

    return app.exec();
}

The QRegExpValidator has its merits (and that's only an understatement). It allows for a bunch of other useful validations:

QRegExp("[1-9][0-9]*")    //  leading digit must be 1 to 9 (prevents leading zeroes).
QRegExp("\\d*")           //  allows matching for unicode digits (e.g. for 
                          //    Arabic-Indic numerals such as ???).
QRegExp("[0-9]+")         //  input must have at least 1 digit.
QRegExp("[0-9]{8,32}")    //  input must be between 8 to 32 digits (e.g. for some basic
                          //    password/special-code checks).
QRegExp("[0-1]{,4}")      //  matches at most four 0s and 1s.
QRegExp("0x[0-9a-fA-F]")  //  matches a hexadecimal number with one hex digit.
QRegExp("[0-9]{13}")      //  matches exactly 13 digits (e.g. perhaps for ISBN?).
QRegExp("[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}")
                          //  matches a format similar to an ip address.
                          //    N.B. invalid addresses can still be entered: "999.999.999.999".     

More On Line-edit Behaviour

According to documentation:

Note that if there is a validator set on the line edit, the returnPressed()/editingFinished() signals will only be emitted if the validator returns QValidator::Acceptable.

Thus, the line-edit will allow the user to input digits even if the minimum amount has not yet been reached. For example, even if the user hasn't inputted any text against the regex "[0-9]{3,}" (which requires at least 3 digits), the line-edit still allows the user to type input to reach that minimum requirement. However, if the user finishes editing without satsifying the requirement of "at least 3 digits", the input would be invalid; the signals returnPressed() and editingFinished() won't be emitted.

If the regex had a maximum-bound (e.g. "[0-1]{,4}"), then the line-edit will stop any input past 4 characters. Additionally, for character sets (i.e. [0-9], [0-1], [0-9A-F], etc.) the line-edit only allows characters from that particular set to be inputted.

_{Note that I've only tested this with Qt 5.11 on a macOS, not on other Qt versions or operating systems. But given Qt's cross-platform schema...}

You can try the FileReader API. Do something like this:

<!DOCTYPE html>
<html>
  <head>
    <script>        
      function handleFileSelect()
      {               
        if (!window.File || !window.FileReader || !window.FileList || !window.Blob) {
          alert('The File APIs are not fully supported in this browser.');
          return;
        }   
      
        var input = document.getElementById('fileinput');
        if (!input) {
          alert("Um, couldn't find the fileinput element.");
        }
        else if (!input.files) {
          alert("This browser doesn't seem to support the `files` property of file inputs.");
        }
        else if (!input.files[0]) {
          alert("Please select a file before clicking 'Load'");               
        }
        else {
          var file = input.files[0];
          var fr = new FileReader();
          fr.onload = receivedText;
          //fr.readAsText(file);
          //fr.readAsBinaryString(file); //as bit work with base64 for example upload to server
          fr.readAsDataURL(file);
        }
      }
      
      function receivedText() {
        document.getElementById('editor').appendChild(document.createTextNode(fr.result));
      }           
      
    </script>
  </head>
  <body>
    <input type="file" id="fileinput"/>
    <input type='button' id='btnLoad' value='Load' onclick='handleFileSelect();' />
    <div id="editor"></div>
  </body>
</html>

Actually I don't like the GOTO command too, but it's in official Microsoft materials, and here are all allowed syntaxes.

If the end point of the statement list of a switch section is reachable, a compile-time error occurs. This is known as the "no fall through" rule. The example

switch (i) {
case 0:
   CaseZero();
   break;
case 1:
   CaseOne();
   break;
default:
   CaseOthers();
   break;
}

is valid because no switch section has a reachable end point. Unlike C and C++, execution of a switch section is not permitted to "fall through" to the next switch section, and the example

switch (i) {
case 0:
   CaseZero();
case 1:
   CaseZeroOrOne();
default:
   CaseAny();
}

results in a compile-time error. When execution of a switch section is to be followed by execution of another switch section, an explicit goto case or goto default statement must be used:

switch (i) {
case 0:
   CaseZero();
   goto case 1;
case 1:
   CaseZeroOrOne();
   goto default;
default:
   CaseAny();
   break;
}

Multiple labels are permitted in a switch-section. The example

switch (i) {
case 0:
   CaseZero();
   break;
case 1:
   CaseOne();
   break;
case 2:
default:
   CaseTwo();
   break;
}

I believe in this particular case, the GOTO can be used, and it's actually the only way to fallthrough.

Looks like you runs out of swap memory, try this

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
/sbin/swapon /var/swap.1

as mentioned by @BlackBurn027 on comments below, this solution was described in here

You can use double join, if table A B are connected only by table AB.

public static Specification<A> findB(String input) {
    return (Specification<A>) (root, cq, cb) -> {
        Join<A,AB> AjoinAB = root.joinList(A_.AB_LIST,JoinType.LEFT);
        Join<AB,B> ABjoinB = AjoinAB.join(AB_.B,JoinType.LEFT);
        return cb.equal(ABjoinB.get(B_.NAME),input);
    };
}

That's just an another option
Sorry for that timing but I have came across this question and I also wanted to make SELECT IN but I didn't even thought about double join. I hope it will help someone.

make sure the input-name[] is in inverted commas in the ruleset. Took me hours to figure that part out.

$('#testform').validate({
  rules : {
    "name[]": { required: true, minlength: 1 }
  }
});

I am supposing you are trying to create a effect, where the textbox contains a label. And when the user click in the textbox, it disappears and lets the user input the text. You do not require Jquery for this.

<input type="text" value="Input Text" onfocus="this.value=''" onblur="(this.value=='')? this.value='Input Text':this.value;" />

Demo

See short-circuit evaluation for the explanation. It's a common way of implementing these operators; it is not unique to JavaScript.

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

int32 and time.Duration are different types. You need to convert the int32 to a time.Duration, such as time.Sleep(time.Duration(rand.Int31n(1000)) * time.Millisecond).

The stash command will stash any changes you have made since your last commit. In your case there is no reason to stash if you are gonna continue working on it the next day. I would only use stash to undo changes that you don't want to commit.

Alternate solution. I prefer this for the brevity and code simplicity.

(function () {
    alert("I am here");
})();

This is an anonymous function, where the name is not specified. What happens here is that, the function is defined and executed together. Add this to the beginning or end of the body, depending on if it is to be executed before loading the page or soon after all the HTML elements are loaded.

It's the part of the .NET Framework that isn't contained within the Client Profile. See MSDN for more info; specifically:

The .NET Framework is made up of the .NET Framework 4 Client Profile and .NET Framework 4 Extended components that exist separately in Programs and Features.

If, as I just encountered, you happen to have a jar file listed in the Project Structures->Libraries that is not in your classpath, the correct answer can be found by following the link given by @CrazyCoder above: Look here http://www.jetbrains.com/idea/webhelp/configuring-module-dependencies-and-libraries.html

This says that to add the jar file as a module dependency within the Project Structure dialog:

1. Open Project Structure
2. Select Modules, then click on the module for which you want the dependency
3. Choose the Dependencies tab
4. Click the '+' at the bottom of the page and choose the appropriate way to connect to the library file. If the jar file is already listed in Libraries, then select 'Library'.

I would recommend you to install django-extensions and use python manage.py reset_db command. It does exactly what you want.

The solution for this one I used (back to the days while learning PHP) without any in-functions:

$days = (int)($uptime/86400); //1day = 86400seconds
$rdays = (uptime-($days*86400)); 
//seconds remaining after uptime was converted into days
$hours = (int)($rdays/3600);//1hour = 3600seconds,converting remaining seconds into hours
$rhours = ($rdays-($hours*3600));
//seconds remaining after $rdays was converted into hours
$minutes = (int)($rhours/60); // 1minute = 60seconds, converting remaining seconds into minutes
echo "$days:$hours:$minutes";

Though this was an old question, new learners who come across this, may find this answer useful.

From ScottGu's blog:

Starting with the ASP.NET MVC 3 Beta release, you can now add a file called _ViewStart.cshtml (or _ViewStart.vbhtml for VB) underneath the \Views folder of your project:

The _ViewStart file can be used to define common view code that you want to execute at the start of each View’s rendering. For example, we could write code within our _ViewStart.cshtml file to programmatically set the Layout property for each View to be the SiteLayout.cshtml file by default:

Because this code executes at the start of each View, we no longer need to explicitly set the Layout in any of our individual view files (except if we wanted to override the default value above).

Important: Because the _ViewStart.cshtml allows us to write code, we can optionally make our Layout selection logic richer than just a basic property set. For example: we could vary the Layout template that we use depending on what type of device is accessing the site – and have a phone or tablet optimized layout for those devices, and a desktop optimized layout for PCs/Laptops. Or if we were building a CMS system or common shared app that is used across multiple customers we could select different layouts to use depending on the customer (or their role) when accessing the site.

This enables a lot of UI flexibility. It also allows you to more easily write view logic once, and avoid repeating it in multiple places.

Also see this.

In a more general sense this ability of MVC framework to "know" about _Viewstart.cshtml is called "Coding by convention".

Convention over configuration (also known as coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility. The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called “sales” by default. It is only if one deviates from this convention, such as calling the table “products_sold”, that one needs to write code regarding these names.

Wikipedia

There's no magic to it. Its just been written into the core codebase of the MVC framework and is therefore something that MVC "knows" about. That why you don't find it in the .config files or elsewhere; it's actually in the MVC code. You can however override to alter or null out these conventions.

SELECT * FROM ALL_OBJECTS WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE')

The column STATUS tells you whether the object is VALID or INVALID. If it is invalid, you have to try a recompile, ORACLE can't tell you if it will work before.

Answering my own question after 5 years as i feel it still need more details

Abstraction:

Technical Definition :- Abstraction is a concept to hide unnecessary details(complex or simple) and only show the essential features of the object. There is no implementaion here its just an concept

What it means practically:- When i say my company needs some medium/device so that employees can connect to customer . This is the purest form of abstaction(like interface in java) as that device/medium can be phone or internet or skype or in person or email etc. I am not going into nitty gritty of device/medium

Even when i say my company needs some medium/device so that employees can connect to customer through voice call. Then also i am talking abstract but at bit lower level as device/medium can be phone or skype or something else etc

Now when i say my company needs some phone so that employees can connect to customer through voice call. Then also i am talking abstract but at bit lower level as phone can be of any company like iphone or samsung or nokia etc

Encapsulation:- Its basically about hiding the state(information) of object with the help of modifiers like private,public,protected etc. we expose the state thru public methods only if require.

What it means practically:- Now when i say my company needs some iphone so that employees can connect to customer through voice call.Now i am talking about some concrete object(like iphone). Even though i am not going into nitty gritty of iphone here too but iphone has some state/concrecrete info/implementation associated with it where device/medium does not have. When i say concrete object, actually it means any object which has some(not complete like java abstract class) implementation/info associated with it.

So iphone actually used here encapsulation as strategy to hide its state/information and expose only the ones which it think should be exposed. So both abstraction and encapsulation hides some unnecessary details but abstraction at the concept level and encapsulation actually at implementation level

This is the gist based on answers in this post and below ones

1. difference between abstraction and encapsulation?
2. encapsulation vs abstraction real world example

You can try DexPatcher. It even integrates with Android Studio. It uses Apktool and Dex2Jar internally.
You can use those tools independently as well. Apktool decompiles apk, and extracts .dex files, which can further be converted to jar using Dex2Jar. Jar can be decompiled by using JD-GUI. You can see the Java code with the help of that tool. Although the similarity of decompiled code to the actual code cannot be guaranteed. There are some advanced code obfuscation tools available in the market, which mess up the code to make it difficult to decompile / understand. eg. Proguard

You are not returning a response object from your view my_form_post. The function ends with implicit return None, which Flask does not like.

Make the function my_form_post return an explicit response, for example

return 'OK'

at the end of the function.

To get size of viewport on load and on resize (based on SimaWB response):

function getViewport() {
    var viewportWidth = $(window).width();
    var viewportHeight = $(window).height();
    $('#viewport').html('Viewport: '+viewportWidth+' x '+viewportHeight+' px');
}

getViewport();

$(window).resize(function() {
    getViewport()
});

Should you ever crave deeper understanding, I heartily recommend Patterson and Hennessy as an intro and Hennessy and Patterson as an intermediate to advanced text. They're pricey, but truly non-pareil; I just wish either or both were available when I got my Masters' degree and entered the workforce designing chips, systems, and parts of system software for them (but, alas!, that was WAY too long ago;-). Stack pointers are so crucial (and the distinction between a microprocessor and any other kind of CPU so utterly meaningful in this context... or, for that matter, in ANY other context, in the last few decades...!-) that I doubt anything but a couple of thorough from-the-ground-up refreshers can help!-)

In some circumstances it might be useful to simply remove the bindings and then re-apply:

ko.cleanNode(document.getElementById(element_id))
ko.applyBindings(viewModel, document.getElementById(element_id))

For me it turned out that I had a @JsonManagedReferece in one entity without a @JsonBackReference in the other referenced entity. This caused the marshaller to throw an error.

Am I missing something? You can just convert offer_date in the comparison:

SELECT *
FROM offers
WHERE to_char(offer_date, 'YYYYMM') = (SELECT to_date(create_date, 'YYYYMM') FROM customers where id = '12345678') AND
      offer_rate > 0 

Maybe better document.querySelectorAll(".col1") because getElementsByClassName doesn't works in IE 8 and querySelectorAll does (althought CSS2 selectors only).

I think this syntax has not been mentionned yet (in the case you want a method without arguments) :

class Clazz {
  static <T> T doIt() {
    // shake that booty
  }
}

And the call :

String str = Clazz.<String>doIt();

Hope this help someone.

You can use the following array methods to obtain a column from a 2D array:

Array.prototype.map()

const array_column = (array, column) => array.map(e => e[column]);

Array.prototype.reduce()

const array_column = (array, column) => array.reduce((a, c) => {
  a.push(c[column]);
  return a;
}, []);

Array.prototype.forEach()

const array_column = (array, column) => {
  const result = [];

  array.forEach(e => {
    result.push(e[column]);
  });

  return result;
};

If your 2D array is a square (the same number of columns for each row), you can use the following method:

Array.prototype.flat() / .filter()

const array_column = (array, column) => array.flat().filter((e, i) => i % array.length === column);

First of all you should stop using mysql_*. MySQL supports multiple inserting like

INSERT INTO example
VALUES
  (100, 'Name 1', 'Value 1', 'Other 1'),
  (101, 'Name 2', 'Value 2', 'Other 2'),
  (102, 'Name 3', 'Value 3', 'Other 3'),
  (103, 'Name 4', 'Value 4', 'Other 4');

You just have to build one string in your foreach loop which looks like that

$values = "(100, 'Name 1', 'Value 1', 'Other 1'), (100, 'Name 1', 'Value 1', 'Other 1'), (100, 'Name 1', 'Value 1', 'Other 1')";

and then insert it after the loop

$sql = "INSERT INTO email_list (R_ID, EMAIL, NAME) VALUES ".$values;

Another way would be Prepared Statements, which are even more suited for your situation.

In case it's useful to anyone. For AngularJS 1.5x I wanted to set CSRF for all requests and I found that when I did this:

$httpProvider.defaults.headers.get = { 'CSRF-Token': afToken }; 
$httpProvider.defaults.headers.put = { 'CSRF-Token': afToken };
$httpProvider.defaults.headers.post = { 'CSRF-Token': afToken }; 

Angular removed the content type so I had to add this:

$httpProvider.defaults.headers.common = { "Content-Type": "application/json"};

Otherwise I get a 415 media type error.

So I am doing this to configure my application for all requests:

angular.module("myapp.maintenance", [])
    .controller('maintenanceCtrl', MaintenanceCtrl)
    .directive('convertToNumber', ConvertToNumber)
    .config(configure);

MaintenanceCtrl.$inject = ["$scope", "$http", "$sce", "$window", "$document", "$timeout", "$filter", 'alertService'];
configure.$inject = ["$httpProvider"];

// configure the header tokens for  CSRF for http operations in this module
function configure($httpProvider) {

    const afToken = angular.element('input[id="__AntiForgeryToken"]').attr('value');

    $httpProvider.defaults.headers.get = { 'CSRF-Token': afToken }; // only added for GET
    $httpProvider.defaults.headers.put = { 'CSRF-Token': afToken }; // added for PUT
    $httpProvider.defaults.headers.post = { 'CSRF-Token': afToken }; // added for POST

    // for some reason if we do the above we have to set the default content type for all 
    // looks like angular clears it when we add our own headers
    $httpProvider.defaults.headers.common = { "Content-Type": "application/json" };

}

It seems that it doesn't turn it into a string. Try

row.HeaderCell.Value = String.Format("{0}", row.Index + 1);

Here is one way to do it:

>>> n = 46
>>> (n + 9) // 10 * 10
50

Set args = Wscript.Arguments

For Each arg In args
  Wscript.Echo arg
Next

From a command prompt, run the script like this:

CSCRIPT MyScript.vbs 1 2 A B "Arg with spaces"

Will give results like this:

1
2
A
B
Arg with spaces

It's currently working, I've just changed the operator > in order to work in the snippet, take a look:

window.onload = function() {_x000D_
_x000D_
  if (window.location.href.indexOf("test") <= -1) {_x000D_
    var search_span = document.getElementsByClassName("securitySearchQuery");_x000D_
    search_span[0].style.color = "blue";_x000D_
    search_span[0].style.fontWeight = "bold";_x000D_
    search_span[0].style.fontSize = "40px";_x000D_

}

<h1 class="keyword-title">Search results for<span class="securitySearchQuery"> "hi".</span></h1>

If you're using swift , use like this. Don't Use storyboard to select row height. Programmatically set table row height like this,

 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    if indexPath.row == 0 || indexPath.row == 1{
        let cell = self.tableView.dequeueReusableCellWithIdentifier("section1", forIndexPath: indexPath) as! Section1TableViewCell
        self.tableView.rowHeight = 150
        cell.label1.text = "hiiiiii"
        cell.label2.text = "Huiiilllllll"
        return cell

    } else {

        let cell = self.tableView.dequeueReusableCellWithIdentifier("section2", forIndexPath: indexPath) as! Section2TableViewCell
        self.tableView.rowHeight = 60
        cell.label3.text = "llll"
        return cell
    }

}

Open a viewcontroller with SWRevealViewController From App delegate.

 self.window = UIWindow(frame: UIScreen.main.bounds)
 let storyboard = UIStoryboard(name: "StoryboardName", bundle: nil)
 let swrevealviewcontroller:SWRevealViewController = storyboard.instantiateInitialViewController() as! SWRevealViewController 
 self.window?.rootViewController = swrevealviewcontroller
 self.window?.makeKeyAndVisible()

            };
        }

        @Override
        public BinaryOperator<StringBuilder> combiner() { return null; }

        @Override
        public Function<StringBuilder, StringBuilder> finisher() { return Function.identity(); }

        @Override
        public Set<Characteristics> characteristics() { return Collections.singleton(Characteristics.IDENTITY_FINISH); }
    }
}

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.

import numpy as np    
hist, bin_edges = np.histogram([1, 1, 2, 2, 2, 2, 3], bins = range(5))

Below, hist indicates that there are 0 items in bin #0, 2 in bin #1, 4 in bin #3, 1 in bin #4.

print(hist)
# array([0, 2, 4, 1])   

bin_edges indicates that bin #0 is the interval [0,1), bin #1 is [1,2), ..., bin #3 is [3,4).

print (bin_edges)
# array([0, 1, 2, 3, 4]))  

Play with the above code, change the input to np.histogram and see how it works.

But a picture is worth a thousand words:

import matplotlib.pyplot as plt
plt.bar(bin_edges[:-1], hist, width = 1)
plt.xlim(min(bin_edges), max(bin_edges))
plt.show()   

You need a reference to the class that contains the method you want to call. Let's say we have two classes, A and B. B has a method you want to call from A. Class A would look like this:

public class A
{
    B b; // A reference to B

    b = new B(); // Creating object of class B

    b.doSomething();  // Calling a method contained in class B from class A
}

B, which contains the doSomething() method would look like this:

public class B
{
    public void doSomething()
    {
        System.out.println("Look, I'm doing something in class B!");
    }
}

Happened the same to me. It turns out that

var data = $("#myObject").data();

gives you a non-writable object. I solved it using:

var data = $.extend({}, $("#myObject").data());

And from then on, data was a standard, writable JS object.

If you are getting this error in Workbench but you are able to log in from terminal then follow this steps.

First simply log in with your current password:

sudo mysql -u root -p

Then change your password because having low strength password gives error sometimes.

ALTER USER 'root'@'localhost' IDENTIFIED BY 'new-strong-password';

FLUSH PRIVILEGES;

Then simply exit and again login with your new password:

quit

sudo mysql -u root -p

Once you successfully logged in type the command:

use mysql;

It should show a message like 'Database changed' then type:

UPDATE user SET plugin='mysql_native_password' WHERE User='root';

After that type:

UPDATE mysql.user set authentication_string=PASSWORD('new-strong-password') where user='root';

Then type:

FLUSH PRIVILEGES;

Then simply exit:

quit

Now try to log in with your new password in your WORKBENCH. Hope it will work. Thank you.

From Linux Change Default User Home Directory While Adding A New User:

Simply open this file using a text editor, type:

vi /etc/default/useradd

The default home directory defined by HOME variable, find line that read as follows:

HOME=/home

Replace with:

HOME=/iscsi/user

Save and close the file. Now you can add user using regular useradd command:

# useradd vivek
# passwd vivek

Verify user information:

# finger vivek

I usually manually set the port that I am listening on in the app.js file (assuming you are using express.js

var server = app.listen(8080, function() {
    console.log('Ready on port %d', server.address().port);
});

This will log Ready on port 8080 to your console.

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

Update 2017 - Test and Results

    var newNo = Math.floor(Math.random()*60000+10000);
    if (!o[newNo.toString()]) o[newNo.toString()] = {id: newNo, name: 'test'};
    if (!a2[newNo]) a2[newNo] = {id: newNo, name: 'test' };
    a1.push({id: newNo, name: 'test'});
}

Original Post - Explanation

There are some misconceptions in your question.

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

These are arrays:

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

This is an array, too:

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

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

This is an object:

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

Here is a performance test of three possibilities:

Lookup Array vs Holey Array vs Object Performance Test

The problem with doing an svn merge as suggested by Sean Bright is that is reintroduces other changes made in the same revision as the deletion. An svn copy is a more targeted operation that will only affect the deleted files.

Using Tortoise SVN you can resurrect a file that has been deleted from your working copy directory and from later SVN revisions, via a svn copy as follows:

• Browse to the working copy folder that previously contained the file.
• Right click on the folder in Explorer, go to TortoiseSVN -> Show log.
• Right click on the revision number just prior to the revision that deleted the file and select "Browse repository".
• Right click on the deleted file and select "Copy to working copy..." and save.

The deleted file will now be in the working copy folder. To re-add it back to SVN, right click on the restored file and select SVN Commit.

NB: This method will preserve the previous history of the restored file, however to see the prior history in the TortoiseSVN log you need to make sure "Stop on copy/rename" is unchecked in the Log messages dialog.

If the two controller is nested in One controller.
Then you can simply call:

$scope.parentmethod();  

Angular will search for parentmethod function starting with current scope and up until it will reach the rootScope.

if you have multiple Java versions installed and need to keep those, you need to check following things:

• JAVA_HOME pointing to your jdk1.8
• in your PATH variable you need to check that jdk1.8\bin path is before the other jdk\bin paths

A good start would be validating the input. In other words, you can make sure that the user has indeed typed a correct path for a real existing file, like this:

import os
fileName = input("Please enter the name of the file you'd like to use.")
while not os.path.isfile(fileName):
    fileName = input("Whoops! No such file! Please enter the name of the file you'd like to use.")

This is with a little help from the built in module os, That is a part of the Standard Python Library.

This works well for me.
Close all the previous activities as follows:

    Intent intent = new Intent(this, MainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("Exit me", true);
    startActivity(intent);
    finish();

Then in MainActivity onCreate() method add this to finish the MainActivity

    setContentView(R.layout.main_layout);

    if( getIntent().getBooleanExtra("Exit me", false)){
        finish();
        return; // add this to prevent from doing unnecessary stuffs
    }

You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document

ORDER BY column OFFSET 0 ROWS

Surprisingly makes it work, what a strange feature.

A bigger example with a CTE as a way to temporarily "store" a long query to re-order it later:

;WITH cte AS (
    SELECT .....long select statement here....
)

SELECT * FROM 
(
    SELECT * FROM 
    ( -- necessary to nest selects for union to work with where & order clauses
        SELECT * FROM cte WHERE cte.MainCol= 1 ORDER BY cte.ColX asc OFFSET 0 ROWS 
    ) first
    UNION ALL
    SELECT * FROM 
    (  
        SELECT * FROM cte WHERE cte.MainCol = 0 ORDER BY cte.ColY desc OFFSET 0 ROWS 
    ) last
) as unionized
ORDER BY unionized.MainCol desc -- all rows ordered by this one
OFFSET @pPageSize * @pPageOffset ROWS -- params from stored procedure for pagination, not relevant to example
FETCH FIRST @pPageSize ROWS ONLY -- params from stored procedure for pagination, not relevant to example

So we get all results ordered by MainCol

But the results with MainCol = 1 get ordered by ColX

And the results with MainCol = 0 get ordered by ColY

add this to your stylesheet. line-height should match the height of your logo

.navbar-nav li a {
 line-height: 50px;
}

We can create a new CSS class for div.

 .div {
      position: absolute;
      left: 150px;
      width: 200px;
      height: 120px;
    }

As the documentation states, 'replace' determines whether the current element is replaced by the directive. The other option is whether it is just added to as a child basically. If you look at the source of your plnkr, notice that for the second directive where replace is false that the div tag is still there. For the first directive it is not.

First result:

<span myd1="">directive template1</span>

Second result:

<div myd2=""><span>directive template2</span></div>

Main culprit for this error is logic which determines encoding when converting Stream or byte[] array to .NET string.

Using StreamReader created with 2nd constructor parameter detectEncodingFromByteOrderMarks set to true, will determine proper encoding and create string which does not break XmlDocument.LoadXml method.

public string GetXmlString(string url)
{
    using var stream = GetResponseStream(url);
    using var reader = new StreamReader(stream, true);
    return reader.ReadToEnd(); // no exception on `LoadXml`
}

Common mistake would be to just blindly use UTF8 encoding on the stream or byte[]. Code bellow would produce string that looks valid when inspected in Visual Studio debugger, or copy-pasted somewhere, but it will produce the exception when used with Load or LoadXml if file is encoded differently then UTF8 without BOM.

public string GetXmlString(string url)
{
    byte[] bytes = GetResponseByteArray(url);
    return System.Text.Encoding.UTF8.GetString(bytes); // potentially exception on `LoadXml`
}

The following steps work fine on macOS Sierra 10.12.4. Note that after brew installs Docker, the docker command (symbolic link) is not available at /usr/local/bin. Running the Docker app for the first time creates this symbolic link. See the detailed steps below.

1. Install Docker.

   brew cask install docker
   

2. Launch Docker.

   • Press ? + Space to bring up Spotlight Search and enter Docker to launch Docker.
   • In the Docker needs privileged access dialog box, click OK.
   • Enter password and click OK.

   When Docker is launched in this manner, a Docker whale icon appears in the status menu. As soon as the whale icon appears, the symbolic links for docker, docker-compose, docker-credential-osxkeychain and docker-machine are created in /usr/local/bin.

   $ ls -l /usr/local/bin/docker*
   lrwxr-xr-x  1 susam  domain Users  67 Apr 12 14:14 /usr/local/bin/docker -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-compose -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-compose
   lrwxr-xr-x  1 susam  domain Users  90 Apr 12 14:14 /usr/local/bin/docker-credential-osxkeychain -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-credential-osxkeychain

3. Click on the docker whale icon in the status menu and wait for it to show Docker is running.

   

4. Test that docker works fine.

   $ docker run hello-world

   Hello from Docker!
   This message shows that your installation appears to be working correctly.
   
   To generate this message, Docker took the following steps:
    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    3. The Docker daemon created a new container from that image which runs the
       executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it
       to your terminal.
   
   To try something more ambitious, you can run an Ubuntu container with:
    $ docker run -it ubuntu bash

5. If you are going to use docker-machine to create virtual machines, install VirtualBox.

   brew cask install virtualbox
   

   Note that if VirtualBox is not installed, then docker-machine fails with the following error.

   $ docker-machine create manager
   Running pre-create checks...
   Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"

I'm adding this answer not because it's likely to be helpful but just because it's true.

In addition to using the existing answers explaining how to make more than one translation by chaining them, you can also construct the 4x4 matrix yourself

I grabbed the following image from some random site I found while googling which shows rotational matrices:

Rotation around x axis:
Rotation around y axis:
Rotation around z axis:

I couldn't find a good example of translation, so assuming I remember/understand it right, translation:

[1 0 0 0]
[0 1 0 0]
[0 0 1 0]
[x y z 1]

See more at the Wikipedia article on transformation as well as the Pragamatic CSS3 tutorial which explains it rather well. Another guide I found which explains arbitrary rotation matrices is Egon Rath's notes on matrices

Matrix multiplication works between these 4x4 matrices of course, so to perform a rotation followed by a translation, you make the appropriate rotation matrix and multiply it by the translation matrix.

This can give you a bit more freedom to get it just right, and will also make it pretty much completely impossible for anyone to understand what it's doing, including you in five minutes.

But, you know, it works.

Edit: I just realized that I missed mentioning probably the most important and practical use of this, which is to incrementally create complex 3D transformations via JavaScript, where things will make a bit more sense.

Each tablespace has one or more datafiles that it uses to store data.

The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.

To find out if the actual limit is 32gb, run the following:

select value from v$parameter where name = 'db_block_size';

Compare the result you get with the first column below, and that will indicate what your max datafile size is.

I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).

Block Sz   Max Datafile Sz (Gb)   Max DB Sz (Tb)

--------   --------------------   --------------

   2,048                  8,192          524,264

   4,096                 16,384        1,048,528

   8,192                 32,768        2,097,056

  16,384                 65,536        4,194,112

  32,768                131,072        8,388,224

You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):

select bytes/1024/1024 as mb_size,
       maxbytes/1024/1024 as maxsize_set,
       x.*
from   dba_data_files x

MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).

If your datafile has a low max size or autoextend is not on you could simply run:

alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;

However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:

alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;

Think of a situation like this,

• You have a database with data.
• There are a number of different applications needed to access that central database, and in the future some new applications too.
• If you are going to insert the inline database queries to access the central database, inside each application's code individually, then probably you have to duplicate the same query again and again inside different applications' code.
• In that kind of a situation, you can use stored procedures (SPs). With stored procedures, you are writing number of common queries (procedures) and store them with the central database.
• Now the duplication of work will never happen as before and the data access and the maintenance will be done centrally.

NOTE:

• In the above situation, you may wonder "Why cannot we introduce a central data access server to interact with all the applications? Yes. That will be a possible alternative. But,
• The main advantage with SPs over that approach is, unlike your data-access-code with inline queries, SPs are pre-compiled statements, so they will execute faster. And communication costs (over networks) will be at a minimum.
• Opposite to that, SPs will add some more load to the database server. If that would be a concern according to the situation, a centralized data access server with inline queries will be a better choice.

Your DemoApplication class is in the com.ag.digital.demo.boot package and your LoginBean class is in the com.ag.digital.demo.bean package. By default components (classes annotated with @Component) are found if they are in the same package or a sub-package of your main application class DemoApplication. This means that LoginBean isn't being found so dependency injection fails.

There are a couple of ways to solve your problem:

1. Move LoginBean into com.ag.digital.demo.boot or a sub-package.
2. Configure the packages that are scanned for components using the scanBasePackages attribute of @SpringBootApplication that should be on DemoApplication.

A few of other things that aren't causing a problem, but are not quite right with the code you've posted:

• @Service is a specialisation of @Component so you don't need both on LoginBean
• Similarly, @RestController is a specialisation of @Component so you don't need both on DemoRestController
• DemoRestController is an unusual place for @EnableAutoConfiguration. That annotation is typically found on your main application class (DemoApplication) either directly or via @SpringBootApplication which is a combination of @ComponentScan, @Configuration, and @EnableAutoConfiguration.

Parcelable vs Serializable I refer these two.

For Java and Kotlin

1) Java

Serializable, the Simplicity

What is Serializable?

Serializable is a standard Java interface. It is not a part of the Android SDK. Its simplicity is its beauty. Just by implementing this interface your POJO will be ready to jump from one Activity to another.

public class TestModel implements Serializable {

String name;

public TestModel(String name) {
    this.name = name;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}
}

• The beauty of serializable is that you only need to implement the Serializable interface on a class and its children. It is a marker interface, meaning that there is no method to implement, Java will simply do its best effort to serialize it efficiently.

• The problem with this approach is that reflection is used and it is a slow process. This mechanism also tends to create a lot of temporary objects and cause quite a bit of garbage collection.

Parcelable, The Speed

What is Parcelable?

Parcelable is another interface. Despite its rival (Serializable in case you forgot), it is a part of the Android SDK. Now, Parcelable was specifically designed in such a way that there is no reflection when using it. That is because we are being really explicit for the serialization process.

public class TestModel implements Parcelable {


String name;

public TestModel(String name, String id) {
    this.name = name;
}

protected TestModel(Parcel in) {
    this.name = in.readString();


}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

@Override
public int describeContents() {
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeString(this.name);

}

public static final Parcelable.Creator<TestModel> CREATOR = new Parcelable.Creator<TestModel>() {
    @Override
    public TestModel createFromParcel(Parcel source) {
        return new TestModel(source);
    }

    @Override
    public TestModel[] newArray(int size) {
        return new TestModel[size];
    }
};
}

Now, The winner is

The results of the tests conducted by Philippe Breault show that Parcelable is more than 10x faster than Serializable. Some other Google engineers stand behind this statement as well.

According to them, the default Serializable approach is slower than Parcelable. And here we have an agreement between the two parties! BUT, it is unfair to compare these two at all! Because with Parcelable we are actually writing custom code. Code specifically created for that one POJO. Thus, no garbage is created and the results are better. But with the default Serializable approach, we rely on the automatic serialization process of Java. The process is apparently not custom at all and creates lots of garbage! Thus, the worse results.

Stop Stop!!!!, Before making decision

Now, there is another approach. The whole automatic process behind Serializable can be replaced by custom code which uses writeObject() & readObject() methods. These methods are specific. If we want to rely on the Serializable approach in combination with custom serialization behavior, then we must include these two methods with the same exact signature as the one below:

 private void writeObject(java.io.ObjectOutputStream out)
 throws IOException;

 private void readObject(java.io.ObjectInputStream in)
     throws IOException, ClassNotFoundException;

 private void readObjectNoData()
     throws ObjectStreamException;

And now a comparison between Parcelable and custom Serializable seems fair! The results may be surprising! The custom Serializable approach is more than 3x faster for writes and 1.6x faster for reads than Parcelable.

Edited:-----

2) Kotlinx Serialization

Kotlinx Serialization Library

For Kotlin serialization need to add below dependency and plugin

implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime:0.9.1"

apply plugin: 'kotlinx-serialization'

Your build.gradle file

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlinx-serialization'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.smile.kotlinxretrosample"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime:0.9.1"
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.squareup.retrofit2:retrofit:2.5.0'
    implementation 'com.squareup.okhttp3:okhttp:3.12.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

Serializing is done quite easily, you need to annotate the intended class with the @Serializable annotation as below

import kotlinx.serialization.Serializable
@Serializable
class Field {
    var count: Int = 0
    var name: String = ""
}

Two more annotations to note are transient and optional. Using transient will have the serializer ignore that field and using optional will allow the serializer not to break if a field is missing, but at the same time a default value will need to be provided.

@Optional
var isOptional: Boolean = false
@Transient
var isTransient: Boolean = false

Note: This can as well work with data classes.

Now to actually use this in action let’s take an example of how to convert a JSON to object and back

 fun toObject(stringValue: String): Field {
        return JSON.parse(Field.serializer(), stringValue)
    }

    fun toJson(field: Field): String {
        //Notice we call a serializer method which is autogenerated from our class 
        //once we have added the annotation to it
        return JSON.stringify(Field.serializer(), field)
    }

In addition to Reed Copsey's answer:

• The worst case is where the two files are identical. In this case it's best to compare the files byte-by-byte.

• If if the two files are not identical, you can speed things up a bit by detecting sooner that they're not identical.

For example, if the two files are of different length then you know they cannot be identical, and you don't even have to compare their actual content.

When you need cookies from session to session, there is another way to do it. Use the Chrome options user-data-dir in order to use folders as profiles. I run:

# You need to: from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("user-data-dir=selenium") 
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("www.google.com")

Here you can do the logins that check for human interaction. I do this and then the cookies I need now every time I start the Webdriver with that folder everything is in there. You can also manually install the Extensions and have them in every session.

The second time I run, all the cookies are there:

# You need to: from selenium.webdriver.chrome.options import Options    
chrome_options = Options()
chrome_options.add_argument("user-data-dir=selenium") 
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("www.google.com") # Now you can see the cookies, the settings, extensions, etc., and the logins done in the previous session are present here. 

The advantage is you can use multiple folders with different settings and cookies, Extensions without the need to load, unload cookies, install and uninstall Extensions, change settings, change logins via code, and thus no way to have the logic of the program break, etc.

Also, this is faster than having to do it all by code.

This worked for me. may help some one. Turn off firewall. on RHEL 7

systemctl stop  firewalld

You can browse all the jQuery plugins tagged with "cookie" here:

http://plugins.jquery.com/plugin-tags/cookies

Plenty of options there.

Check out the one called jQuery Storage, which takes advantage of HTML5's localStorage. If localStorage isn't available, it defaults to cookies. However, it doesn't allow you to set expiration.

An alternative quick and hacky solution if you want to get an overview of all the produres there are, or run into the issue of only getting the procedure header shown by SHOW CREATE PROCEDURE:

mysqldump --user=<user> -p --no-data --routines <database>

It will export the table descriptions as well, but no data. Works well for sniffing around unknown or forgotten schemas... ;)

You can use order() to sort date data.

# Sort date ascending order
d[order(as.Date(d$V3, format = "%d/%m/%Y")),]

# Sort date descending order
d[rev(order(as.Date(d$V3, format = "%d/%m/%y"))),]

Hope this helps,

In your asp.net app use this

using System.Configuration;
Response.Write(ConfigurationManager.OpenMachineConfiguration().FilePath);

I'm not familiar with the library, but if your problem is that you don't want a byte array, one easy way is to specify an encoding type straight in a cast:

>>> my_byte_str
b'Hello World'

>>> str(my_byte_str, 'utf-8')
'Hello World'

I'm a Perl user, an a game we have is to find every different ways to increment a variable... that's not really different here. The answer to how many ways to find the sum of the elements of a vector in C++ is probably an infinity...

My 2 cents:

Using BOOST_FOREACH, to get free of the ugly iterator syntax:

sum = 0;
BOOST_FOREACH(int & x, myvector){
  sum += x;
}

iterating on indices (really easy to read).

int i, sum = 0;
for (i=0; i<myvector.size(); i++){
  sum += myvector[i];
}

This other one is destructive, accessing vector like a stack:

while (!myvector.empty()){
   sum+=myvector.back();
   myvector.pop_back();
}

You could do something like this:

htmlComponent.ts

htmlVariable: string = "<b>Some html.</b>"; //this is html in TypeScript code that you need to display

htmlComponent.html

<div [innerHtml]="htmlVariable"></div> //this is how you display html code from TypeScript in your html
