You can use a join to do this

SELECT t1.* from myTable t1
LEFT OUTER JOIN myTable t2 on t2.ID=t1.ID AND t2.`Date` > t1.`Date`
WHERE t2.`Date` IS NULL;

Only rows which have the latest date for each ID with have a NULL join to t2.

I changed the import sequence without fixing the problem, until finally I installed moments and tempus dominius (Core and bootrap), using npm and include them in boostrap.js

try {
window.Popper = require('popper.js').default;
window.$ = window.jQuery = require('jquery');
require('moment'); /*added*/
require('bootstrap');
require('tempusdominus-bootstrap-4');/*added*/} catch (e) {}

I encountered a similar problem in my project. After struggling a lot, I found this solution:

if ($.datepicker.parseDate("dd/mm/yy","17/06/2015") > $.datepicker.parseDate("dd/mm/yy","20/06/2015"))
    // do something

You DO NOT NEED plugins like jQuery Validate or Moment.js for this issue. Hope this solution helps.

For Persian culture

PersianCalendar pc = new PersianCalendar();            

var today = pc.GetDayOfMonth(DateTime.Now);
var firstDayOfMonth = pc.GetDayOfMonth(DateTime.Now.AddDays(-(today-1)));
var lastDayOfMonth = pc.GetDayOfMonth(DateTime.Now.AddMonths(1).AddDays(-today));            
Console.WriteLine("First day "+ firstDayOfMonth);
Console.WriteLine("Last day " + lastDayOfMonth);

My first suggestion would be use your calendar table, if you don't have one, then create one. They are very useful. Your query is then as simple as:

DECLARE @MinDate DATE = '20140101',
        @MaxDate DATE = '20140106';

SELECT  Date
FROM    dbo.Calendar
WHERE   Date >= @MinDate
AND     Date < @MaxDate;

If you don't want to, or can't create a calendar table you can still do this on the fly without a recursive CTE:

DECLARE @MinDate DATE = '20140101',
        @MaxDate DATE = '20140106';

SELECT  TOP (DATEDIFF(DAY, @MinDate, @MaxDate) + 1)
        Date = DATEADD(DAY, ROW_NUMBER() OVER(ORDER BY a.object_id) - 1, @MinDate)
FROM    sys.all_objects a
        CROSS JOIN sys.all_objects b;

For further reading on this see:

• Generate a set or sequence without loops – part 1
• Generate a set or sequence without loops – part 2
• Generate a set or sequence without loops – part 3

With regard to then using this sequence of dates in a cursor, I would really recommend you find another way. There is usually a set based alternative that will perform much better.

So with your data:

  date   | it_cd | qty 
24-04-14 |  i-1  | 10 
26-04-14 |  i-1  | 20

To get the quantity on 28-04-2014 (which I gather is your requirement), you don't actually need any of the above, you can simply use:

SELECT  TOP 1 date, it_cd, qty 
FROM    T
WHERE   it_cd = 'i-1'
AND     Date <= '20140428'
ORDER BY Date DESC;

If you don't want it for a particular item:

SELECT  date, it_cd, qty 
FROM    (   SELECT  date, 
                    it_cd, 
                    qty, 
                    RowNumber = ROW_NUMBER() OVER(PARTITION BY ic_id 
                                                    ORDER BY date DESC)
            FROM    T
            WHERE   Date  <= '20140428'
        ) T
WHERE   RowNumber = 1;

maxDate: new Date() 

its working fine for me disable with current date in date range picker

You can use following addon to handle all subquery related function from laravel 5.5+

https://github.com/maksimru/eloquent-subquery-magic

User::selectRaw('user_id,comments_by_user.total_count')->leftJoinSubquery(
  //subquery
  Comment::selectRaw('user_id,count(*) total_count')
      ->groupBy('user_id'),
  //alias
  'comments_by_user', 
  //closure for "on" statement
  function ($join) {
      $join->on('users.id', '=', 'comments_by_user.user_id');
  }
)->get();

$(document).ready(function() {
$("#aDateFrom").datepicker({
    onSelect: function() {
        //- get date from another datepicker without language dependencies
        var minDate = $('#aDateFrom').datepicker('getDate');
        $("#aDateTo").datepicker("change", { minDate: minDate });
    }
});

$("#aDateTo").datepicker({
    onSelect: function() {
        //- get date from another datepicker without language dependencies
        var maxDate = $('#aDateTo').datepicker('getDate');
        $("#aDateFrom").datepicker("change", { maxDate: maxDate });
    }
});
});

Use this one :

 onSelect: function(dateText) {
                 $("input#DateTo").datepicker('option', 'minDate', dateText);
            }

$.browser has been removed from JQuery 1.9. You can to use Modernizr project instead

UPDATE TO SUPPORT IE 10 AND IE 11 (TRIDENT version)

To complete the @daniel.moura answer, here is a version which support IE 11 and +

var matched, browser;

jQuery.uaMatch = function( ua ) {
    ua = ua.toLowerCase();

    var match = /(chrome)[ \/]([\w.]+)/.exec( ua ) ||
        /(webkit)[ \/]([\w.]+)/.exec( ua ) ||
        /(opera)(?:.*version|)[ \/]([\w.]+)/.exec( ua ) ||
        /(msie)[\s?]([\w.]+)/.exec( ua ) ||       
        /(trident)(?:.*? rv:([\w.]+)|)/.exec( ua ) ||
        ua.indexOf("compatible") < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec( ua ) ||
        [];

    return {
        browser: match[ 1 ] || "",
        version: match[ 2 ] || "0"
    };
};

matched = jQuery.uaMatch( navigator.userAgent );
//IE 11+ fix (Trident) 
matched.browser = matched.browser == 'trident' ? 'msie' : matched.browser;
browser = {};

if ( matched.browser ) {
    browser[ matched.browser ] = true;
    browser.version = matched.version;
}

// Chrome is Webkit, but Webkit is also Safari.
if ( browser.chrome ) {
    browser.webkit = true;
} else if ( browser.webkit ) {
    browser.safari = true;
}

jQuery.browser = browser;
// log removed - adds an extra dependency
//log(jQuery.browser)

I did this:

var dateToday = new Date();
var yrRange = dateToday.getFullYear() + ":" + (dateToday.getFullYear() + 50);
and then
yearRange : yrRange

where 50 is the range from current year.

To know the actual date format, insert a record by using sysdate. That way you can find the actual date format. for example

insert into emp values(7936, 'Mac', 'clerk', 7782, sysdate, 1300, 300, 10);

now, select the inserted record.

select ename, hiredate from emp where ename='Mac';

the result is

ENAME   HIREDATE
Mac     06-JAN-13

voila, now your actual date format is found.

You can join the table on itself to get the PK:

Select cpe1.PK, cpe2.MaxDate, cpe1.fmgcms_cpeclaimid 
from Filteredfmgcms_claimpaymentestimate cpe1
INNER JOIN
(
    select MAX(createdon) As MaxDate, fmgcms_cpeclaimid 
    from Filteredfmgcms_claimpaymentestimate
    group by fmgcms_cpeclaimid
) cpe2
    on cpe1.fmgcms_cpeclaimid = cpe2.fmgcms_cpeclaimid
    and cpe1.createdon = cpe2.MaxDate
where cpe1.createdon < 'reportstartdate'

i am using v3.1.3 and i had to use data('DateTimePicker') like this

var fromE = $( "#" + fromInput );
var toE = $( "#" + toInput );
$('.form-datepicker').datetimepicker(dtOpts);

$('.form-datepicker').on('change', function(e){
   var isTo = $(this).attr('name') === 'to';

   $( "#" + ( isTo ? fromInput : toInput  ) )
      .data('DateTimePicker')[ isTo ? 'setMaxDate' : 'setMinDate' ](moment($(this).val(), 'DD/MM/YYYY'))
});

Just want to add this for the future programmer.

This code limits the date min and max. The year is fully controlled by getting the current year as max year.

Hope this could help to anyone.

Here's the code.

var dateToday = new Date();
var yrRange = '2014' + ":" + (dateToday.getFullYear());

$(function () {
    $("[id$=txtDate]").datepicker({
        showOn: 'button',
        changeMonth: true,
        changeYear: true,
        showButtonPanel: true,
        buttonImageOnly: true,
        yearRange: yrRange,
        buttonImage: 'calendar3.png',
        buttonImageOnly: true,
        minDate: new Date(2014,1-1,1),
        maxDate: '+50Y',
        inline:true
    });
});

I have created function to disable previous date, disable flexible weekend days (Like Saturday, Sunday)

We are using beforeShowDay method of jQuery UI datepicker plugin.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
var NotBeforeToday = function(date) {_x000D_
  var now = new Date(); //this gets the current date and time_x000D_
  if (date.getFullYear() == now.getFullYear() && date.getMonth() == now.getMonth() && date.getDate() >= now.getDate() && (date.getDay() > 0 && date.getDay() < 6) )_x000D_
   return [true,""];_x000D_
  if (date.getFullYear() >= now.getFullYear() && date.getMonth() > now.getMonth() && (date.getDay() > 0 && date.getDay() < 6))_x000D_
   return [true,""];_x000D_
  if (date.getFullYear() > now.getFullYear() && (date.getDay() > 0 && date.getDay() < 6))_x000D_
   return [true,""];_x000D_
  return [false,""];_x000D_
 }_x000D_
_x000D_
_x000D_
jQuery("#datepicker").datepicker({_x000D_
  beforeShowDay: NotBeforeToday_x000D_
    });

Here today's date is 15th Sept. I have disabled Saturday and Sunday.

$(".datepicker").datepicker({maxDate: '0'});

This will set the maxDate to +0 days from the current date (i.e. today). See:

http://api.jqueryui.com/datepicker/#option-maxDate

try

$('#page_output').html(str_output);

if you are going to do a query you can join in your Inline Table Valued function like:

SELECT
    a.*,b.*
    FROM AAAA a
        INNER JOIN MyNS.GetUnshippedOrders() b ON a.z=b.z

it will incur little overhead and run fine.

if you try to use your the Multi Statement Table Valued in a similar query, you will have performance issues:

SELECT
    x.a,x.b,x.c,(SELECT OrderQty FROM MyNS.GetLastShipped(x.CustomerID)) AS Qty
    FROM xxxx   x

because you will execute the function 1 time for each row returned, as the result set gets large, it will run slower and slower.

Use

var rootObject =  JsonConvert.DeserializeObject<RootObject>(string json);

Create your classes on JSON 2 C#

Json.NET documentation: Serializing and Deserializing JSON with Json.NET

This works:

$("#datepicker").datepicker({ minDate: +0 });

NSLog(@"%@", digit);

what is shown in console?

String name = "admin";
char[] ch = name.toString().toCharArray(); //it will read and store each character of String and store into char[].

for(int i=0; i<ch.length; i++)
{
    System.out.println(ch[i]+
                       "-->"+
                       (int)ch[i]); //this will print both character and its value
}

The straight answer is already in a duplicate question: Why does the jquery change event not trigger when I set the value of a select using val()?

As you probably know setting the value of the select doesn't trigger the change() event, if you're looking for an event that is fired when an element's value has been changed through JS there isn't one.

If you really want to do this I guess the only way is to write a function that checks the DOM on an interval and tracks changed values, but definitely don't do this unless you must (not sure why you ever would need to)

Added this solution:
Another possible solution would be to create your own .val() wrapper function and have it trigger a custom event after setting the value through .val(), then when you use your .val() wrapper to set the value of a <select> it will trigger your custom event which you can trap and handle.

Be sure to return this, so it is chainable in jQuery fashion

$arrayDecoded = json_decode($arrayEncoded, true);

gives you an array.

For my opinion this is the simplest variant

array.map(({good}) => ({good}))

You need to set the password for root@localhost to be blank. There are two ways:

• The MySQL SET PASSWORD command:

  SET PASSWORD FOR root@localhost=PASSWORD('');
  

• Using the command-line mysqladmin tool:

  mysqladmin -u root -pCURRENTPASSWORD password ''
  

DELETE FROM table_name 
WHERE id BETWEEN 79 AND 296;

Pass in the straight XML instead of a dictionary.

Ruby has no pre/post increment/decrement operator. For instance, x++ or x-- will fail to parse. More importantly, ++x or --x will do nothing! In fact, they behave as multiple unary prefix operators: -x == ---x == -----x == ...... To increment a number, simply write x += 1.

Taken from "Things That Newcomers to Ruby Should Know " (archive, mirror)

That explains it better than I ever could.

EDIT: and the reason from the language author himself (source):

1. ++ and -- are NOT reserved operator in Ruby.
2. C's increment/decrement operators are in fact hidden assignment. They affect variables, not objects. You cannot accomplish assignment via method. Ruby uses +=/-= operator instead.
3. self cannot be a target of assignment. In addition, altering the value of integer 1 might cause severe confusion throughout the program.

I think you are referring to the problem in C (and C++) that returning an array from a function isn't allowed (or at least won't work as expected) - this is because the array return will (if you write it in the simple form) return a pointer to the actual array on the stack, which is then promptly removed when the function returns.

But in this case, it works, because the std::vector is a class, and classes, like structs, can (and will) be copied to the callers context. [Actually, most compilers will optimise out this particular type of copy using something called "Return Value Optimisation", specifically introduced to avoid copying large objects when they are returned from a function, but that's an optimisation, and from a programmers perspective, it will behave as if the assignment constructor was called for the object]

As long as you don't return a pointer or a reference to something that is within the function returning, you are fine.

In 2010 it is Ctrl+k, Ctrl+d. See image below.

Add a static method inside your functional interface

package example;

interface Action<T, U> {
       U execute(T t);
       static  Action<Void,Void> invoke(Runnable runnable){
           return (v) -> {
               runnable.run();
                return null;
            };         
       }
    }

public class Lambda {


    public static void main(String[] args) {

        Action<Void, Void> a = Action.invoke(() -> System.out.println("Do nothing!"));
        Void t = null;
        a.execute(t);
    }

}

Output

Do nothing!

I assume you're running Hadoop on 64bit CentOS. The reason you saw that warning is the native Hadoop library $HADOOP_HOME/lib/native/libhadoop.so.1.0.0 was actually compiled on 32 bit.

Anyway, it's just a warning, and won't impact Hadoop's functionalities.

Here is the way if you do want to eliminate this warning, download the source code of Hadoop and recompile libhadoop.so.1.0.0 on 64bit system, then replace the 32bit one.

Steps on how to recompile source code are included here for Ubuntu:

• http://www.ercoppa.org/Linux-Compile-Hadoop-220-fix-Unable-to-load-native-hadoop-library.htm

Good luck.

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

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

I suggest to run in two steps:

1) generate mapping A that maps A:column index->non zero objects

2) for each object i (row) with non-zero occurrences(columns) {k1,..kn} calculate cosine similarity just for elements in the union set A[k1] U A[k2] U.. A[kn]

Assuming a big sparse matrix with high sparsity this will gain a significant boost over brute force

Almost all CPUs use stack. The program stack is LIFO technique with hardware supported manage.

Stack is amount of program (RAM) memory normally allocated at the top of CPU memory heap and grow (at PUSH instruction the stack pointer is decreased) in opposite direction. A standard term for inserting into stack is PUSH and for remove from stack is POP.

Stack is managed via stack intended CPU register, also called stack pointer, so when CPU perform POP or PUSH the stack pointer will load/store a register or constant into stack memory and the stack pointer will be automatic decreased xor increased according number of words pushed or poped into (from) stack.

Via assembler instructions we can store to stack:

1. CPU registers and also constants.
2. Return addresses for functions or procedures
3. Functions/procedures in/out variables
4. Functions/procedures local variables.

If you know the path of the class or the jar containing the class then add it to your classpath while running it. You can use the classpath as mentioned here:

on Windows

java -classpath .;yourjar.jar YourMainClass

on UNIX/Linux

java -classpath .:yourjar.jar YourMainClass

Select Table Column Name where you want to get default value of Current date

 ALTER TABLE 
 [dbo].[Table_Name]
 ADD  CONSTRAINT [Constraint_Name] 
 DEFAULT (getdate()) FOR [Column_Name]

Alter Table Query

Alter TABLE [dbo].[Table_Name](
    [PDate] [datetime] Default GetDate())

We can use,

$ rails d migration table_name  

Which will delete the migration.

Here you will get list of diffrent ways of applying the click event. You can select accordingly as suaitable or if your click is not working just try an alternative out of these.

$('.clickHere').click(function(){ 
     // this is flat click. this event will be attatched 
     //to element if element is available in 
     //dom at the time when JS loaded. 

  // do your stuff
});

$('.clickHere').on('click', function(){ 
    // same as first one

    // do your stuff
})

$(document).on('click', '.clickHere', function(){
          // this is diffrent type 
          //  of click. The click will be registered on document when JS 
          //  loaded and will delegate to the '.clickHere ' element. This is 
          //  called event delegation 
   // do your stuff
});

$('body').on('click', '.clickHere', function(){
   // This is same as 3rd 
   // point. Here we used body instead of document/

   // do your stuff
});

$('.clickHere').off().on('click', function(){ // 
    // deregister event listener if any and register the event again. This 
    // prevents the duplicate event resistration on same element. 
    // do your stuff
})

Ran into a similar issue the solution for me was to run fuser -k 'filename.db' on the file that had a lock associated with it.

I prefer @Ista solution, cause needs no extra package and is simple.

By some reason, it does not order the way pointed (probably because ordering by the groups). So, another ordering is done.

More actual solution:

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

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

I find the solutions stated above very useful. Especially the Python's Virtual Environment explanation by jrc.

In my case, I was using Docker and was editing 'local' files (not direcly inside the docker). So I installed Remote Development extension by Microsoft.

ext install ms-vscode-remote.vscode-remote-extensionpack

More details can be found at https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.vscode-remote-extensionpack

I should say, it was not easy to play around at first. What worked for me was...
1. starting docker
2. In vscode, Remote-container: Attach to running container
3. Adding folder /code/<path-to-code-folder> from root of the machine to vscode

and then installing python extension + pylint

Do you mean bulletpoints? • • •

Depends on what you see as false in a string.

Empty string, the word false, 0, should all those be false or is only empty false or only the word false.

You probably need to buid your own method to test the string and return true or false to be 100 % sure that it does what you need.

We use getters and setters:

• for reusability
• to perform validation in later stages of programming

Getter and setter methods are public interfaces to access private class members.

Encapsulation mantra

The encapsulation mantra is to make fields private and methods public.

Getter Methods: We can get access to private variables.

Setter Methods: We can modify private fields.

Even though the getter and setter methods do not add new functionality, we can change our mind come back later to make that method

• better;
• safer; and
• faster.

Anywhere a value can be used, a method that returns that value can be added. Instead of:

int x = 1000 - 500

use

int x = 1000 - class_name.getValue();

In layman's terms

Suppose we need to store the details of this Person. This Person has the fields name, age and sex. Doing this involves creating methods for name, age and sex. Now if we need create another person, it becomes necessary to create the methods for name, age, sex all over again.

Instead of doing this, we can create a bean class(Person) with getter and setter methods. So tomorrow we can just create objects of this Bean class(Person class) whenever we need to add a new person (see the figure). Thus we are reusing the fields and methods of bean class, which is much better.

You can take advantage of the head() (or first()) functions to see if the DataFrame has a single row. If so, it is not empty.

>>> dic0 = {'dic0':0}
>>> dic1 = {'dic1':1}
>>> ndic = dict(dic0.items() + dic1.items())
>>> ndic
{'dic0': 0, 'dic1': 1}
>>>

Try this:

$("#myId > UL > LI")

    $oblast = Oblast::all();
    $category = Category::where('slug', $catName)->first();
    $availableProjects = $category->availableProjects;
    return view('pages.business-area')->with(array('category'=>$category, 'availableProjects'=>$availableProjects, 'oblast'=>$oblast));

import random 
import string

def get_random_string(size):
    chars = string.ascii_lowercase+string.ascii_uppercase+string.digits
    ''.join(random.choice(chars) for _ in range(size))

print(get_random_string(20)

output : FfxjmkyyLG5HvLeRudDS

Is this what you are after? Just index the element and assign a new value.

A[2,1]=150

Assumption:

Phpunit (3.7) is available in the console environment.

Action:

Enter the following command in the console:

SHELL> phpunit "{{PATH TO THE FILE}}"

Comments:

You do not need to include anything in the new versions of PHPUnit unless you do not want to run in the console. For example, running tests in the browser.

A few points:

1. Command-line parameters are accessible via commandArgs(), so see help(commandArgs) for an overview.

2. You can use Rscript.exe on all platforms, including Windows. It will support commandArgs(). littler could be ported to Windows but lives right now only on OS X and Linux.

3. There are two add-on packages on CRAN -- getopt and optparse -- which were both written for command-line parsing.

Edit in Nov 2015: New alternatives have appeared and I wholeheartedly recommend docopt.

This problem is absent not only with SQL data sources but with Object Data Sources as well. However, when setting the DataSource dynamically in code, that's when this goes bad. Unfortunately, MSDN sometimes is really very poor on information. A simple mentioning of this behavior(this is not a bug but a design issue) would save a lot of time. Anyhow, I'm not very inclined to use Session variables for this. I usually store the sorting direction in a ViewState.

If you need a simple working solution, try using DefaultTableModel.

If you have created your own table model, that extends AbstractTableModel, then you should also implement removeRow() method. The exact implementation depends on the underlying structure, that you have used to store data.

For example, if you have used Vector, then it may be something like this:

public class SimpleTableModel extends AbstractTableModel {
    private Vector<String> columnNames = new Vector<String>();
    // Each value in the vector is a row; String[] - row data;
    private Vector<String[]> data = new Vector<String[]>();

    ...

    public String getValueAt(int row, int col) {
        return data.get(row)[col];
    }

    ...

    public void removeRow(int row) {
        data.removeElementAt(row);
    }
}

If you have used List, then it would be very much alike:

// Each item in the list is a row; String[] - row data;
List<String[]> arr = new ArrayList<String[]>();

public void removeRow(int row) {
    data.remove(row);
}

HashMap:

//Integer - row number; String[] - row data;
HashMap<Integer, String[]> data = new HashMap<Integer, String[]>();

public void removeRow(Integer row) {
    data.remove(row);
}

And if you are using arrays like this one

String[][] data = { { "a", "b" }, { "c", "d" } };

then you're out of luck, because there is no way to dynamically remove elements from arrays. You may try to use arrays by storing separately some flags notifying which rows are deleted and which are not, or by some other devious way, but I would advise against it... That would introduce unnecessary complexity, and would in fact just be solving a problem by creating another. That's a sure-fire way to end up here. Try one of the above ways to store your table data instead.

For better understanding of how this works, and what to do to make your own model work properly, I strongly advise you to refer to Java Tutorial, DefaultTableModel API and it's source code.

I was having this same issue this morning. When I checked my Device Manager, it showed COM4 properly, and when I checked in the Arduino IDE COM4 just wasn't an option. Only COM1 was listed.
I tried unplugging and plugging my Arduino in and out a couple more times and eventually COM4 showed up again in the IDE. I didn't have to change any settings.
Hopefully that helps somebody.

There are various ways of changing the status bar color.

1) Using the styles.xml. You can use the android:statusBarColor attribute to do this the easy but static way.

Note: You can also use this attribute with the Material theme.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AppTheme" parent="AppTheme.Base">
        <item name="android:statusBarColor">@android:color/transparent</item>
    </style>
</resources>

2) You can get it done dynamically using the setStatusBarColor(int) method in the Window class. But remember that this method is only available for API 21 or higher. So be sure to check that, or your app will surely crash in lower devices.

Here is a working example of this method.

if (Build.VERSION.SDK_INT >= 21) {
            Window window = getWindow();
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            window.setStatusBarColor(getResources().getColor(R.color.primaryDark));
}

where primaryDark is the 700 tint of the primary color I am using in my app. You can define this color in the colors.xml file.

Do give it a try and let me know if you have any questions. Hope it helps.

User Endless is right,

$.browser.chrome = (typeof window.chrome === "object"); 

code is best to detect Chrome browser using jQuery.

If you using IE and added GoogleFrame as plugin then

var is_chrome = /chrome/.test( navigator.userAgent.toLowerCase() );

code will treat as Chrome browser because GoogleFrame plugin modifying the navigator property and adding chromeframe inside it.

While Guy's answer is correct (and probably fits 9 out of 10 cases), it's worth noting that if you are attempting to do this from a control that already has its DataContext set further up the stack, you'll resetting this when you set DataContext back to itself:

DataContext="{Binding RelativeSource={RelativeSource Self}}"

This will of course then break your existing bindings.

If this is the case, you should set the RelativeSource on the control you are trying to bind, rather than its parent.

i.e. for binding to a UserControl's properties:

Binding Path=PropertyName, 
        RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}

Given how difficult it can be currently to see what's going on with data binding, it's worth bearing this in mind even if you find that setting RelativeSource={RelativeSource Self} currently works :)

You can use Visual Studio for C, but if you are serious about learning the newest C available, I recommend using something like Code::Blocks with MinGW-TDM version, which you can get a 32 bit version of. I use version 5.1 which supports the newest C and C++. Another benefit is that it is a better platform for creating software that can be easily ported to other platforms. If you were, for example, to code in C, using the SDL library, you could create software that could be recompiled with little to no changes to the code, on Linux, Apple and many mobile devices. The way Microsoft has been going these days, I think this is definitely the better route to take.

The answer to this question simply put is: Don't use BOOLEAN with Oracle-- PL/SQL is dumb and it doesn't work. Use another data type to run your process.

A note to SSRS report developers with Oracle datasource: You can use BOOLEAN parameters, but be careful how you implement. Oracle PL/SQL does not play nicely with BOOLEAN, but you can use the BOOLEAN value in the Tablix Filter if the data resides in your dataset. This really tripped me up, because I have used BOOLEAN parameter with Oracle data source. But in that instance I was filtering against Tablix data, not SQL query.

If the data is NOT in your SSRS Dataset Fields, you can rewrite the SQL something like this using an INTEGER parameter:

__

<ReportParameter Name="paramPickupOrders">
  <DataType>Integer</DataType>
  <DefaultValue>
    <Values>
      <Value>0</Value>
    </Values>
  </DefaultValue>
  <Prompt>Pickup orders?</Prompt>
  <ValidValues>
    <ParameterValues>
      <ParameterValue>
        <Value>0</Value>
        <Label>NO</Label>
      </ParameterValue>
      <ParameterValue>
        <Value>1</Value>
        <Label>YES</Label>
      </ParameterValue>
    </ParameterValues>
  </ValidValues>
</ReportParameter>

...

<Query>
<DataSourceName>Gmenu</DataSourceName>
<QueryParameters>
  <QueryParameter Name=":paramPickupOrders">
    <Value>=Parameters!paramPickupOrders.Value</Value>
  </QueryParameter>
<CommandText>
    where 
        (:paramPickupOrders = 0 AND ordh.PICKUP_FLAG = 'N'
        OR :paramPickupOrders = 1 AND ordh.PICKUP_FLAG = 'Y' )

If the data is in your SSRS Dataset Fields, you can use a tablix filter with a BOOLEAN parameter:

__

</ReportParameter>
<ReportParameter Name="paramFilterOrdersWithNoLoad">
  <DataType>Boolean</DataType>
  <DefaultValue>
    <Values>
      <Value>false</Value>
    </Values>
  </DefaultValue>
  <Prompt>Only orders with no load?</Prompt>
</ReportParameter>

...

<Tablix Name="tablix_dsMyData">
<Filters>
  <Filter>
    <FilterExpression>
        =(Parameters!paramFilterOrdersWithNoLoad.Value=false) 
        or (Parameters!paramFilterOrdersWithNoLoad.Value=true and Fields!LOADNUMBER.Value=0)
    </FilterExpression>
    <Operator>Equal</Operator>
    <FilterValues>
      <FilterValue DataType="Boolean">=true</FilterValue>
    </FilterValues>
  </Filter>
</Filters>

In Spring or Spring boot application.properties file here is the way to escape the special characters;

table.whereclause=where id'\='100

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);       

gevang's answer is great. There's another way as well to do this directly by using pcolor. Code:

[X,Y] = meshgrid(-8:.5:8);
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;
figure;
subplot(1,3,1);
pcolor(X,Y,Z); 
subplot(1,3,2);
pcolor(X,Y,Z); shading flat;
subplot(1,3,3);
pcolor(X,Y,Z); shading interp;

Output:

Also, pcolor is flat too, as show here (pcolor is the 2d base; the 3d figure above it is generated using mesh):

You probably have a log4j.properties file somewhere in the project. In that file you can configure which level of debug output you want. See this example:

log4j.rootLogger=info, console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

log4j.logger.com.example=debug

The first line sets the log level for the root logger to "info", i.e. only info, warn, error and fatal will be printed to the console (which is the appender defined a little below that).

The last line sets the logger for com.example.* (if you get your loggers via LogFactory.getLogger(getClass())) will be at debug level, i.e. debug will also be printed.

request.args is a MultiDict with the parsed contents of the query string. From the documentation of get method:

get(key, default=None, type=None)

Return the default value if the requested data doesn’t exist. If type is provided and is a callable it should convert the value, return it or raise a ValueError if that is not possible.

For How do I change the overall colors (background and font)?

For MAC : goto Sublime text -> Preferences -> color scheme

You can use "os.sep "

 import os
 pathfile=os.path.dirname(templateFile)
 directory = str(pathfile)+os.sep+'output'+os.sep+'log.txt'
 rootTree.write(directory)

I think you would be look at String class, there are multiple ways to do it. What about substring(int,int) and indexOf(int) lastIndexOf(int)?

The problem may be that ssh is trying to connect to all the different IPs that www.google.com resolves to. For example on my machine:

# ssh -v -o ConnectTimeout=1 -o ConnectionAttempts=1 www.google.com
OpenSSH_5.9p1, OpenSSL 0.9.8t 18 Jan 2012
debug1: Connecting to www.google.com [173.194.43.20] port 22.
debug1: connect to address 173.194.43.20 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.19] port 22.
debug1: connect to address 173.194.43.19 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.18] port 22.
debug1: connect to address 173.194.43.18 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.17] port 22.
debug1: connect to address 173.194.43.17 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.16] port 22.
debug1: connect to address 173.194.43.16 port 22: Connection timed out
ssh: connect to host www.google.com port 22: Connection timed out

If I run it with a specific IP, it returns much faster.

EDIT: I've timed it (with time) and the results are:

• www.google.com - 5.086 seconds
• 173.94.43.16 - 1.054 seconds

Please see my answer here. As dreamwerx.myopenid.com points out, it is possible to do this with SimpleXML, but the DOM extension would be the better and more flexible way. Additionally there is a third way: using XMLWriter. It's much more simple to use than the DOM and therefore it's my preferred way of writing XML documents from scratch.

$w=new XMLWriter();
$w->openMemory();
$w->startDocument('1.0','UTF-8');
$w->startElement("root");
    $w->writeAttribute("ah", "OK");
    $w->text('Wow, it works!');
$w->endElement();
echo htmlentities($w->outputMemory(true));

By the way: DOM stands for Document Object Model; this is the standardized API into XML documents.

This is already in :

Age from Date of Birth using JQuery

or alternatively u can use Date.parse() as in

var date1 = new Date("10/25/2011");
var date2 = new Date("09/03/2010");
var date3 = new Date(Date.parse(date1) - Date.parse(date2));

Consider normalizing to E.164 format. For full international support, you'd need a VARCHAR of 15 digits.

See Twilio's recommendation for more information on localization of phone numbers.

If the case is:

n=int(input())

Instead of -> for i in n: -> gives error- 'int' object is not iterable

Use -> for i in range(0,n): -> works fine..!

None of the above answers worked for me.

This was the solution, from the parent directory run:

git submodule update --init;
cd submodule-directory;
git pull;
cd ..;
git add submodule-directory;

now you can git commit and git push

You can do:

(function($) {
  var YourPlugin = function(element, option) {
    var defaults = {
      //default value
    }

    this.option = $.extend({}, defaults, option);
    this.$element = $(element);
    this.init();
  }

  YourPlugin.prototype = {
    init: function() { },
    show: function() { },
    //another functions
  }

  $.fn.yourPlugin = function(option) {
    var arg = arguments,
        options = typeof option == 'object' && option;;
    return this.each(function() {
      var $this = $(this),
          data = $this.data('yourPlugin');

      if (!data) $this.data('yourPlugin', (data = new YourPlugin(this, options)));
      if (typeof option === 'string') {
        if (arg.length > 1) {
          data[option].apply(data, Array.prototype.slice.call(arg, 1));
        } else {
          data[option]();
        }
      }
    });
  };
});

In this way your plugins object is stored as data value in your element.

//Initialization without option
$('#myId').yourPlugin();

//Initialization with option
$('#myId').yourPlugin({
  // your option
});

// call show method
$('#myId').yourPlugin('show');

Using $('[data-whatever="myvalue"]') will select anything with html attributes, but in newer jQueries it seems that if you use $(...).data(...) to attach data, it uses some magic browser thingy and does not affect the html, therefore is not discovered by .find as indicated in the previous answer.

Verify (tested with 1.7.2+) (also see fiddle): (updated to be more complete)

var $container = $('<div><div id="item1"/><div id="item2"/></div>');

// add html attribute
var $item1 = $('#item1').attr('data-generated', true);

// add as data
var $item2 = $('#item2').data('generated', true);

// create item, add data attribute via jquery
var $item3 = $('<div />', {id: 'item3', data: { generated: 'true' }, text: 'Item 3' });
$container.append($item3);

// create item, "manually" add data attribute
var $item4 = $('<div id="item4" data-generated="true">Item 4</div>');
$container.append($item4);

// only returns $item1 and $item4
var $result = $container.find('[data-generated="true"]');

I wanted a solution for Gnu sort on Windows, but none of the above solutions worked for me on the command line.

Using Lloyd's clue, the following batch file (.bat) worked for me.

Type the tab character within the double quotes.

C:\>cat foo.bat

sort -k3 -t"    " tabfile.txt

The current configuration, as used to determine which resources to retrieve, is available from the Resources' Configuration object:

getResources().getConfiguration().orientation;

You can check for orientation by looking at its value:

int orientation = getResources().getConfiguration().orientation;
if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
    // In landscape
} else {
    // In portrait
}

More information can be found in the Android Developer.

You can load the text file into a textfile Hive table and then insert the data from this table into your sequencefile.

Start with a tab delimited file:

% cat /tmp/input.txt
a       b
a2      b2

create a sequence file

hive> create table test_sq(k string, v string) stored as sequencefile;

try to load; as expected, this will fail:

hive> load data local inpath '/tmp/input.txt' into table test_sq;

But with this table:

hive> create table test_t(k string, v string) row format delimited fields terminated by '\t' stored as textfile;

The load works just fine:

hive> load data local inpath '/tmp/input.txt' into table test_t;
OK
hive> select * from test_t;
OK
a       b
a2      b2

Now load into the sequence table from the text table:

insert into table test_sq select * from test_t;

Can also do load/insert with overwrite to replace all.

This is a very common question seen on Stackoverflow.

The important part here is not the command displayed in the error, but what the actual error tells you instead.

a Quick breakdown on why this error is received.

cmd.exe Being a terminal window relies on input and system Environment variables, in order to perform what you request it to do. it does NOT know the location of everything and it also does not know when to distinguish between commands or executable names which are separated by whitespace like space and tab or commands with whitespace as switch variables.

How do I fix this:

When Actual Command/executable fails

First we make sure, is the executable actually installed? If yes, continue with the rest, if not, install it first.

If you have any executable which you are attempting to run from cmd.exe then you need to tell cmd.exe where this file is located. There are 2 ways of doing this.

1. specify the full path to the file.

   "C:\My_Files\mycommand.exe"

2. Add the location of the file to your environment Variables.

Goto:
------> Control Panel-> System-> Advanced System Settings->Environment Variables

In the System Variables Window, locate path and select edit

Now simply add your path to the end of the string, seperated by a semicolon ; as:

;C:\My_Files\

Save the changes and exit. You need to make sure that ANY cmd.exe windows you had open are then closed and re-opened to allow it to re-import the environment variables. Now you should be able to run mycommand.exe from any path, within cmd.exe as the environment is aware of the path to it.

When C:\Program or Similar fails

This is a very simple error. Each string after a white space is seen as a different command in cmd.exe terminal, you simply have to enclose the entire path in double quotes in order for cmd.exe to see it as a single string, and not separate commands.

So to execute C:\Program Files\My-App\Mobile.exe simply run as:

"C:\Program Files\My-App\Mobile.exe"

open div then put

style="width:100% ; margin:0px auto;"

close div

The persistence.xml has a jar-file that you can use. From the Java EE 5 tutorial:

<persistence>
    <persistence-unit name="OrderManagement">
        <description>This unit manages orders and customers.
            It does not rely on any vendor-specific features and can
            therefore be deployed to any persistence provider.
        </description>
        <jta-data-source>jdbc/MyOrderDB</jta-data-source>
        <jar-file>MyOrderApp.jar</jar-file>
        <class>com.widgets.Order</class>
        <class>com.widgets.Customer</class>
    </persistence-unit>
</persistence>

This file defines a persistence unit named OrderManagement, which uses a JTA-aware data source jdbc/MyOrderDB. The jar-file and class elements specify managed persistence classes: entity classes, embeddable classes, and mapped superclasses. The jar-file element specifies JAR files that are visible to the packaged persistence unit that contain managed persistence classes, while the class element explicitly names managed persistence classes.

In the case of Hibernate, have a look at the Chapter2. Setup and configuration too for more details.

EDIT: Actually, If you don't mind not being spec compliant, Hibernate supports auto-detection even in Java SE. To do so, add the hibernate.archive.autodetection property:

<persistence-unit name="eventractor" transaction-type="RESOURCE_LOCAL">
  <!-- This is required to be spec compliant, Hibernate however supports
       auto-detection even in JSE.
  <class>pl.michalmech.eventractor.domain.User</class>
  <class>pl.michalmech.eventractor.domain.Address</class>
  <class>pl.michalmech.eventractor.domain.City</class>
  <class>pl.michalmech.eventractor.domain.Country</class>
   -->

  <properties>
    <!-- Scan for annotated classes and Hibernate mapping XML files -->
    <property name="hibernate.archive.autodetection" value="class, hbm"/>

    <property name="hibernate.hbm2ddl.auto" value="validate" />
    <property name="hibernate.show_sql" value="true" />
  </properties>
</persistence-unit>

var results = from c in db.Companies
              join cn in db.Countries on c.CountryID equals cn.ID
              join ct in db.Cities on c.CityID equals ct.ID
              join sect in db.Sectors on c.SectorID equals sect.ID
              where (c.CountryID == cn.ID) && (c.CityID == ct.ID) && (c.SectorID == company.SectorID) && (company.SectorID == sect.ID)
              select new { country = cn.Name, city = ct.Name, c.ID, c.Name, c.Address1, c.Address2, c.Address3, c.CountryID, c.CityID, c.Region, c.PostCode, c.Telephone, c.Website, c.SectorID, Status = (ContactStatus)c.StatusID, sector = sect.Name };


return results.ToList();

Basically it checks if the value before the || evaluates to true, if yes, it takes this value, if not, it takes the value after the ||.

Values for which it will take the value after the || (as far as i remember):

• undefined
• false
• 0
• '' (Null or Null string)

ActiveRecord::Base.connection.tables.map do |model|
  model.capitalize.singularize.camelize
end

will return

["Article", "MenuItem", "Post", "ZebraStripePerson"]

Additional information If you want to call a method on the object name without model:string unknown method or variable errors use this

model.classify.constantize.attribute_names

Or do apply:

df['col1'].apply(lambda x: {1: "A", 2: "B"}.get(x,x))

Demo:

>>> df['col1']=df['col1'].apply(lambda x: {1: "A", 2: "B"}.get(x,x))
>>> df
  col1 col2
0    w    a
1    1    2
2    2  NaN
>>> 

Here is a small example you can run to test it:

[1,2,3,4,5,6,7,8,9].forEach(function(n){
    var sum = 0;
    console.log('Start for:' + n);
    for (var i = 0; i < ( 10 - n) * 100000000; i++)
        sum++;

    console.log('Ended for:' + n, sum);
});

It will produce something like this(if it takes too less/much time, increase/decrease the number of iterations):

(index):48 Start for:1
(index):52 Ended for:1 900000000
(index):48 Start for:2
(index):52 Ended for:2 800000000
(index):48 Start for:3
(index):52 Ended for:3 700000000
(index):48 Start for:4
(index):52 Ended for:4 600000000
(index):48 Start for:5
(index):52 Ended for:5 500000000
(index):48 Start for:6
(index):52 Ended for:6 400000000
(index):48 Start for:7
(index):52 Ended for:7 300000000
(index):48 Start for:8
(index):52 Ended for:8 200000000
(index):48 Start for:9
(index):52 Ended for:9 100000000
(index):45 [Violation] 'load' handler took 7285ms

You can do this using the query builder. Just use SELECT instead of TABLE and GET.

DB::select('select * from user where name = ?',['Jhon']);

Notes: 1. Multiple question marks are allowed. 2. The second parameter must be an array, even if there is only one parameter. 3. Laravel will automatically clean parameters, so you don't have to.

Further info here: http://laravel.com/docs/5.0/database#running-queries

Hmmmmmm, turns out that still returns a standard class for me when I don't use a where clause. I found this helped:

foreach($results as $result)
{
print_r(get_object_vars($result));
}

However, get_object_vars isn't recursive, so don't use it on $results.

Start with this:

Set fso = CreateObject("Scripting.FileSystemObject")
If (fso.FileExists(path)) Then
   msg = path & " exists."
Else
   msg = path & " doesn't exist."
End If

Taken from the documentation.

Update

The below made sense for 2013. However, now, I would use the :not() selector as described below.

CSS can be overwritten.

DEMO: http://jsfiddle.net/persianturtle/J4SUb/

Use this:

.parent {
  padding: 50px;
  border: 1px solid black;
}

.parent span {
  position: absolute;
  top: 200px;
  padding: 30px;
  border: 10px solid green;
}

.parent:hover span {
  border: 10px solid red;
}

.parent span:hover {
  border: 10px solid green;
}

<a class="parent">
    Parent text
    <span>Child text</span>    
</a>

If data.frame columns are different types, apply() has a problem. A subtlety about row iteration is how apply(a.data.frame, 1, ...) does implicit type conversion to character types when columns are different types; eg. a factor and numeric column. Here's an example, using a factor in one column to modify a numeric column:

mean.height = list(BOY=69.5, GIRL=64.0)

subjects = data.frame(gender = factor(c("BOY", "GIRL", "GIRL", "BOY"))
         , height = c(71.0, 59.3, 62.1, 62.1))

apply(height, 1, function(x) x[2] - mean.height[[x[1]]])

The subtraction fails because the columns are converted to character types.

One fix is to back-convert the second column to a number:

apply(subjects, 1, function(x) as.numeric(x[2]) - mean.height[[x[1]]])

But the conversions can be avoided by keeping the columns separate and using mapply():

mapply(function(x,y) y - mean.height[[x]], subjects$gender, subjects$height)

mapply() is needed because [[ ]] does not accept a vector argument. So the column iteration could be done before the subtraction by passing a vector to [], by a bit more ugly code:

subjects$height - unlist(mean.height[subjects$gender])

In your viewDidLoad, register at notification center to listen to this opened from background action

NotificationCenter.default.addObserver(self, selector:#selector(doSomething), name: NSNotification.Name.UIApplicationWillEnterForeground, object: nil)
        

Then add this function and perform needed action

func doSomething(){
    //...
}

Finally add this function to clean up the notification observer when your view controller is destroyed.

deinit {
    NotificationCenter.default.removeObserver(self)
}

Use a docstring:

A string literal that occurs as the first statement in a module, function, class, or method definition. Such a docstring becomes the __doc__ special attribute of that object.

All modules should normally have docstrings, and all functions and classes exported by a module should also have docstrings. Public methods (including the __init__ constructor) should also have docstrings. A package may be documented in the module docstring of the __init__.py file in the package directory.

String literals occurring elsewhere in Python code may also act as documentation. They are not recognized by the Python bytecode compiler and are not accessible as runtime object attributes (i.e. not assigned to __doc__ ), but two types of extra docstrings may be extracted by software tools:

1. String literals occurring immediately after a simple assignment at the top level of a module, class, or __init__ method are called "attribute docstrings".
2. String literals occurring immediately after another docstring are called "additional docstrings".

Please see PEP 258 , "Docutils Design Specification" [2] , for a detailed description of attribute and additional docstrings...

My try is combined solution.

string = string.replace(',', '.').replace(/[^\d\.]/g, "").replace(/\./, "x").replace(/\./g, "").replace(/x/, ".");
string = Math.round( parseFloat(string) * 100) / 100;

First line solution from here: regex replacing multiple periods in floating number . It replaces comma "," with dot "." ; Replaces first comma with x; Removes all dots and replaces x back to dot.

Second line cleans numbers after dot.

I ran into the 'Expecting: ANY PRIVATE KEY' error when using openssl on Windows (Ubuntu Bash and Git Bash had the same issue).

The cause of the problem was that I'd saved the key and certificate files in Notepad using UTF8. Resaving both files in ANSI format solved the problem.

For sake of gathering all relevant information in one place, here is the official answer to this question - and it is the only one that worked for me on Xcode 5.1.1

I'm assume you cannot get css working for your button using anchor tag. So you need to override the css styles which are being overwritten by other elements using !important property.

HTML

<a href="#" class="selected_btn" data-role="button">Button name</a>

CSS

.selected_btn
{
    border:1px solid red;
    text-decoration:none;
    font-family:helvetica;
    color:red !important;            
    background:url('http://www.lessardstephens.com/layout/images/slideshow_big.png') repeat-x;
}

Here is the demo

One alternative for IE7+ and other browsers may be to use :first-child instead, and invert your styles.

For example, if you're setting the margin on each li:

ul li {
  margin-bottom: 1em;
}
ul li:last-child {
  margin-bottom: 0;
}

You could replace it with this:

ul li {
  margin-top: 1em;
}
ul li:first-child {
  margin-top: 0;
}

This will work well for some other cases like borders.

According to sitepoint, :first-child buggy, but only to the extent that it will select some root elements (the doctype or html), and may not change styles if other elements are inserted.

There are 2 ways to configure custom error pages for ASP.NET sites:

1. Internet Information Services (IIS) Manager (the GUI)
2. web.config file

This article explains how to do each:

• How To Set Up Custom Error Pages In IIS 7.5 With ASP.NET

The reason your error.aspx page is not displaying might be because you have an error in your web.config. Try this instead:

<configuration>
   <system.web>
      <customErrors defaultRedirect="error.aspx" mode="RemoteOnly">
         <error statusCode="404" redirect="error.aspx"/>
      </customErrors>
   </system.web>
</configuration>

You might need to make sure that Error Pages in IIS Manager - Feature Delegation is set to Read/Write:

Also, this answer may help you configure the web.config file:

• What is the difference between customErrors and httpErrors?

Generally what's meant by that is a fairly intimate familiarity with one (or probably more) of the .NET languages (C#, VB.NET, etc.) and one (or less probably more) of the .NET stacks (WinForms, ASP.NET, WPF, etc.).

As for a specific "formal definition", I don't think you'll find one beyond that. The job description should be specific about what they're looking for. I wouldn't consider a job listing that asks for a ".NET developer" and provides no more detail than that to be sufficiently descriptive.

[A-Za-z ]* to match letters and spaces.

The accepted answer above did not work for me, because it ordered the weeks by alphabetical order, not chronological order:

2012/1
2012/10
2012/11
...
2012/19
2012/2

Here's my solution to count and group by week:

SELECT CONCAT(YEAR(date), '/', WEEK(date)) AS week_name, 
       YEAR(date), WEEK(date), COUNT(*)
FROM column_name
GROUP BY week_name
ORDER BY YEAR(DATE) ASC, WEEK(date) ASC

Generates:

YEAR/WEEK   YEAR   WEEK   COUNT
2011/51     2011    51      15
2011/52     2011    52      14
2012/1      2012    1       20
2012/2      2012    2       14
2012/3      2012    3       19
2012/4      2012    4       19

In ViewDidLoad method of ViewController.m

I would suggest you go for bulk insert as suggested in this article : Bulk Insertion of Data Using C# DataTable and SQL server OpenXML function

some applications will treat "localhost" specially. the mysql client will treat localhost as a request to connect to the local unix domain socket instead of using tcp to connect to the server on 127.0.0.1. This may be faster, and may be in a different authentication zone.

I don't know of other apps that treat localhost differently than 127.0.0.1, but there probably are some.

import { ParamMap, Router, ActivatedRoute } from '@angular/router';

constructor(private route: ActivatedRoute) {}

ngOnInit() {
    console.log(this.route.snapshot.queryParamMap);
}

UPDATE

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

export class LoginComponent {
    constructor(private router: Router) {
        const snapshot: RouterStateSnapshot = router.routerState.snapshot;
        console.log(snapshot);  // <-- hope it helps
    }
}

If you have to send a multipart file that is composed, among other things, by an Object that needs to be converted with a specific HttpMessageConverter and you get the "no suitable HttpMessageConverter" error no matter what you try, you may want to try with this:

RestTemplate restTemplate = new RestTemplate();
FormHttpMessageConverter converter = new FormHttpMessageConverter();

converter.addPartConverter(new TheRequiredHttpMessageConverter());
//for example, in my case it was "new MappingJackson2HttpMessageConverter()"

restTemplate.getMessageConverters().add(converter);

This solved the problem for me with a custom Object that, together with a file (instanceof FileSystemResource, in my case), was part of the multipart file I needed to send. I tried with TrueGuidance's solution (and many others found around the web) to no avail, then I looked at FormHttpMessageConverter's source code and tried this.

You can print some text by using SELECT command like that:

SELECT 'some text'

Result:

+-----------+
| some text |
+-----------+
| some text |
+-----------+
1 row in set (0.02 sec)

Refer to Concatenating Strings in Django Templates:

1. For earlier versions of Django:

   {{ "Mary had a little"|stringformat:"s lamb." }}

"Mary had a little lamb."

2. Else:

   {{ "Mary had a little"|add:" lamb." }}

"Mary had a little lamb."

You have a couple of problems here.

First, the XSD has an issue where an element is both named or referenced; in your case should be referenced.

Change:

<xsd:element name="stock" ref="Stock" minOccurs="1" maxOccurs="unbounded"/> 

To:

<xsd:element name="stock" type="Stock" minOccurs="1" maxOccurs="unbounded"/> 

And:

• Remove the declaration of the global element Stock
• Create a complex type declaration for a type named Stock

So:

<xsd:element name="Stock">
    <xsd:complexType>

To:

<xsd:complexType name="Stock">

Make sure you fix the xml closing tags.

The second problem is that the correct way to reference an external XSD is to use XSD schema with import/include within a wsdl:types element. wsdl:import is reserved to referencing other WSDL files. More information is available by going through the WS-I specification, section WSDL and Schema Import. Based on WS-I, your case would be:

INCORRECT: (the way you showed it)

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <import namespace="http://stock.com/schemas/services/stock" location="Stock.xsd" />
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

CORRECT:

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <types>
        <schema xmlns="http://www.w3.org/2001/XMLSchema">
            <import namespace="http://stock.com/schemas/services/stock" schemaLocation="Stock.xsd" />             
        </schema>
    </types>
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

SOME processors may support both syntaxes. The XSD you put out shows issues, make sure you first validate the XSD.

It would be better if you go the WS-I way when it comes to WSDL authoring.

Other issues may be related to the use of relative vs. absolute URIs in locating external content.

        return super.onOptionsItemSelected(item);
    }

    @Override
    public boolean onMenuItemClick(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.item1:
                // handle it
                break;
            case R.id.item2:
                // do whatever
                break;
            // and so on...
        }
        return false;
    }
}

If you are trying to clear out a receive buffer for something that receives strings I have found the best way is to use memset as described above. The reason is that no matter how big the next received string is (limited to sizeof buffer of course), it will automatically be an asciiz string if written into a buffer that has been pre-zeroed.

To get the first n elements of an array, use

array.slice(0, n);

You should iterate over the keys and get the values using square brackets.

See: How do I enumerate the properties of a javascript object?

EDIT: Obviously, this makes the question a duplicate.

You can use Array.push() for appending elements to an array.

For deleting, it is best to use this.$delete(array, index) for reactive objects.

Vue.delete( target, key ): Delete a property on an object. If the object is reactive, ensure the deletion triggers view updates. This is primarily used to get around the limitation that Vue cannot detect property deletions, but you should rarely need to use it.

Have you verified that there is in fact a row where Staff_Id = @PersonID? What you've posted works fine in a test script, assuming the row exists. If you comment out the insert statement, then the error is raised.

set nocount on

create table Timesheet_Hours (Staff_Id int, BookedHours int, Posted_Flag bit)

insert into Timesheet_Hours (Staff_Id, BookedHours, Posted_Flag) values (1, 5.5, 0)

declare @PersonID int
set @PersonID = 1

IF EXISTS    
    (
    SELECT 1    
    FROM Timesheet_Hours    
    WHERE Posted_Flag = 1    
        AND Staff_Id = @PersonID    
    )    
    BEGIN
        RAISERROR('Timesheets have already been posted!', 16, 1)
        ROLLBACK TRAN
    END
ELSE
    IF NOT EXISTS
        (
        SELECT 1
        FROM Timesheet_Hours
        WHERE Staff_Id = @PersonID
        )
        BEGIN
            RAISERROR('Default list has not been loaded!', 16, 1)
            ROLLBACK TRAN
        END
    ELSE
        print 'No problems here'

drop table Timesheet_Hours

The latest way to go is to use the unit 'ch' which stands for character.

You can simply write:

p { max-width: 75ch; }

The only trick is that whitespaces won't be counted as characters..

Don't get confused with the concepts of Angular and RxJS

We have pipes concept in Angular and pipe() function in RxJS.

1) Pipes in Angular: A pipe takes in data as input and transforms it to the desired output
https://angular.io/guide/pipes

2) pipe() function in RxJS: You can use pipes to link operators together. Pipes let you combine multiple functions into a single function.

The pipe() function takes as its arguments the functions you want to combine, and returns a new function that, when executed, runs the composed functions in sequence.
https://angular.io/guide/rx-library (search for pipes in this URL, you can find the same)

So according to your question, you are referring pipe() function in RxJS

Working JavaScript code:

<div id="div_add" class="div_add">Add class from Javascript</div>
<div id="div_replace" class="div_replace">Replace class from Javascript</div>
<div id="div_remove" class="div_remove">Remove class from Javascript</div>
<button onClick="div_add_class();">Add class from Javascript</button>
<button onClick="div_replace_class();">Replace class from Javascript</button>
<button onClick="div_remove_class();">Remove class from Javascript</button>
<script type="text/javascript">
    function div_add_class()
    {
        document.getElementById("div_add").className += " div_added";
    }
    function div_replace_class()
    {
        document.getElementById("div_replace").className = "div_replaced";
    }
    function div_remove_class()
    {
        document.getElementById("div_remove").className = "";
    }
</script>

You can download a working code from this link.

If you want to prompt the user to select a file, then read its contents:

// read the contents of a file input
const readInputFile = (inputElement, callback) => {
  const reader = new FileReader();
  reader.onload = () => {
    callback(reader.result)
  };
  reader.readAsText(inputElement.files[0]);
};
// create a file input and destroy it after reading it
export const openFile = (callback) => {
  var el = document.createElement('input');
  el.setAttribute('type', 'file');
  el.style.display = 'none';
  document.body.appendChild(el);
  el.onchange = () => {readInputFile(el, (data) => {
    callback(data)
    document.body.removeChild(el);
  })}
  el.click();
}

Usage:

// prompt the user to select a file and read it
openFile(data => {
    console.log(data)
  })

You don't need awk for this...

echo aaa0.bbb.ccc | cut -d. -f1
cut -d. -f1 <<< aaa0.bbb.ccc

echo aaa0.bbb.ccc | { IFS=. read a _ ; echo $a ; }
{ IFS=. read a _ ; echo $a ; } <<< aaa0.bbb.ccc 

x=aaa0.bbb.ccc; echo ${x/.*/}

Heavier options:

sed:
echo aaa0.bbb.ccc | sed 's/\..*//'
sed 's/\..*//' <<< aaa0.bbb.ccc 
awk:
echo aaa0.bbb.ccc | awk -F. '{print $1}'
awk -F. '{print $1}' <<< aaa0.bbb.ccc

            }
            return 0;
    }

EDIT

I want to add the reason that your IF statement seems to not work. When you do an EXISTS on an aggregate, it's always going to be true. It returns a value even if the ID doesn't exist. Sure, it's NULL, but its returning it. Instead, do this:

if exists(select 1 from table where id = 4)

and you'll get to the ELSE portion of your IF statement.

Now, here's a better, set-based solution:

update b
  set code = isnull(a.value, 123)
from #b b
left join (select id, max(value) from #a group by id) a
  on b.id = a.id
where
  b.id = yourid

This has the benefit of being able to run on the entire table rather than individual ids.

The method you are looking for is jQuery's .text() and you can used it in the following fashion:

$('#a_tbnotesverbergen').text('text here');

The accepted answer still threw a Javascript error in IE for me (for Angular 1.2 at least). It is a bug but the workaround is to use ngAttr detailed on https://docs.angularjs.org/guide/interpolation

<input type="text" ng-model="inputText" ng-attr-placeholder="{{somePlaceholder}}" />

Issue: https://github.com/angular/angular.js/issues/5025

Just for fun, this one also works.

a = num;
b = 0;
if (a % 10 == 0)
  return a == 0;
do {
  b = 10 * b + a % 10;
  if (a == b)
    return true;
  a = a / 10;
} while (a > b);
return a == b;

String methodName= "...";
String[] args = {};

Method[] methods = clazz.getMethods();
for (Method m : methods) {
    if (methodName.equals(m.getName())) {
        // for static methods we can use null as instance of class
        m.invoke(null, new Object[] {args});
        break;
    }
}

I'm using a custom view that I layout on top of the other ones and that just draws the 4 small corners in the same color as the background. This works whatever the view contents are and does not allocate much memory.

public class RoundedCornersView extends View {
    private float mRadius;
    private int mColor = Color.WHITE;
    private Paint mPaint;
    private Path mPath;

    public RoundedCornersView(Context context) {
        super(context);
        init();
    }

    public RoundedCornersView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();

        TypedArray a = context.getTheme().obtainStyledAttributes(
                attrs,
                R.styleable.RoundedCornersView,
                0, 0);

        try {
            setRadius(a.getDimension(R.styleable.RoundedCornersView_radius, 0));
            setColor(a.getColor(R.styleable.RoundedCornersView_cornersColor, Color.WHITE));
        } finally {
            a.recycle();
        }
    }

    private void init() {
        setColor(mColor);
        setRadius(mRadius);
    }

    private void setColor(int color) {
        mColor = color;
        mPaint = new Paint();
        mPaint.setColor(mColor);
        mPaint.setStyle(Paint.Style.FILL);
        mPaint.setAntiAlias(true);

        invalidate();
    }

    private void setRadius(float radius) {
        mRadius = radius;
        RectF r = new RectF(0, 0, 2 * mRadius, 2 * mRadius);
        mPath = new Path();
        mPath.moveTo(0,0);
        mPath.lineTo(0, mRadius);
        mPath.arcTo(r, 180, 90);
        mPath.lineTo(0,0);
        invalidate();
    }

    @Override
    protected void onDraw(Canvas canvas) {

        /*Paint paint = new Paint();
        paint.setColor(Color.RED);
        canvas.drawRect(0, 0, mRadius, mRadius, paint);*/

        int w = getWidth();
        int h = getHeight();
        canvas.drawPath(mPath, mPaint);
        canvas.save();
        canvas.translate(w, 0);
        canvas.rotate(90);
        canvas.drawPath(mPath, mPaint);
        canvas.restore();
        canvas.save();
        canvas.translate(w, h);
        canvas.rotate(180);
        canvas.drawPath(mPath, mPaint);
        canvas.restore();
        canvas.translate(0, h);
        canvas.rotate(270);
        canvas.drawPath(mPath, mPaint);
    }
}

If you are using Hibernate 3.6 you can use the code in the accepted answer (provided by Brian Deterling) with slight modification:

  CriteriaImpl c = (CriteriaImpl) criteria;
  SessionImpl s = (SessionImpl) c.getSession();
  SessionFactoryImplementor factory = (SessionFactoryImplementor) s.getSessionFactory();
  String[] implementors = factory.getImplementors(c.getEntityOrClassName());
  LoadQueryInfluencers lqis = new LoadQueryInfluencers();
  CriteriaLoader loader = new CriteriaLoader((OuterJoinLoadable) factory.getEntityPersister(implementors[0]), factory, c, implementors[0], lqis);
  Field f = OuterJoinLoader.class.getDeclaredField("sql");
  f.setAccessible(true);
  String sql = (String) f.get(loader);

These are the shift operators

x << y Returns x with the bits shifted to the left by y places (and new bits on the right-hand-side are zeros). This is the same as multiplying x by 2**y.

x >> y Returns x with the bits shifted to the right by y places. This is the same as //'ing x by 2**y.

The user that is configured to run this scheduled task must have "Log on as a batch job" rights on the computer that hosts the exe you are launching. This can be configured on the local security policy of the computer that hosts the exe. You can change the policy (on the server hosting the exe) under

Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment -> Log On As Batch Job

Add your user to this list (you could also make the user account a local admin on the machine hosting the exe).

Finally, you could also simply copy your exe from the network location to your local computer and run it from there instead.

Note also that a domain policy could be restricting "Log on as a batch job" rights at your organization.

try this..

<tr ng-repeat='item in items'>
<td>{{item.Name}}</td>
<td>{{item.Price}}</td>
<td>{{item.Quantity}}</td>
</tr>

Create a footer view layout consisting of text that you want to set as footer and then try

View footerView = ((LayoutInflater) ActivityContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
ListView.addFooterView(footerView);

Layout for footer could be something like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingTop="7dip"
    android:paddingBottom="7dip"
    android:orientation="horizontal"
    android:gravity="center">

    <LinearLayout 
        android:id="@+id/footer_layout" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:gravity="center"
        android:layout_gravity="center">

    <TextView 
        android:text="@string/footer_text_1" 
        android:id="@+id/footer_1" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:textSize="14dip" 
        android:textStyle="bold" 
        android:layout_marginRight="5dip" />
    </LinearLayout>
</LinearLayout> 

The activity class could be:

public class MyListActivty extends ListActivity {
    private Context context = null;
    private ListView list = null;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        list = (ListView)findViewById(android.R.id.list);

        //code to set adapter to populate list
        View footerView =  ((LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
        list.addFooterView(footerView);
    }
}

This is a "feature" of the M2E plugin that had been introduced a while ago. It's not directly related to the JBoss EAR plugin but also happens with most other Maven plugins.

If you have a plugin execution defined in your pom (like the execution of maven-ear-plugin:generate-application-xml), you also need to add additional config information for M2E that tells M2E what to do when the build is run in Eclipse, e.g. should the plugin execution be ignored or executed by M2E, should it be also done for incremental builds, ... If that information is missing, M2E complains about it by showing this error message:

"Plugin execution not covered by lifecycle configuration"

See here for a more detailed explanation and some sample config that needs to be added to the pom to make that error go away:

https://www.eclipse.org/m2e/documentation/m2e-execution-not-covered.html

Using Java 7

Map<String,String> sampleMap = new HashMap<>();
for (sampleMap.Entry<String,String> entry : sampleMap.entrySet()) {
    String key = entry.getKey();
    String value = entry.getValue();

    /* your Code as per the Business Justification  */

}

Using Java 8

Map<String,String> sampleMap = new HashMap<>();

sampleMap.forEach((k, v) -> System.out.println("Key is :  " + k + " Value is :  " + v));

The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

Two ways I've used it... first:

SET /P variable=

When batch file reaches this point (when left blank) it will halt and wait for user input. Input then becomes variable.

And second:

SET /P variable=<%temp%\filename.txt

Will set variable to contents (the first line) of the txt file. This method won't work unless the /P is included. Both tested on Windows 8.1 Pro, but it's the same on 7 and 10.

To modify a global variable inside a function, you must use the global keyword.

When you try to do this without the line

global counter

inside of the definition of increment, a local variable named counter is created so as to keep you from mucking up the counter variable that the whole program may depend on.

Note that you only need to use global when you are modifying the variable; you could read counter from within increment without the need for the global statement.

Goto->Special->blanks does not like merged cells. Try unmerging cells above the range in which you want to select blanks then try again.

I think you should call the super.draw() method first before you do anything in surfaceView's draw method.

You can do it like this:

var mongoose = require('mongoose');
var _id = mongoose.mongo.BSONPure.ObjectID.fromHexString("4eb6e7e7e9b7f4194e000001");

EDIT: New standard has fromHexString rather than fromString

Thank you php-b-grader. I improved the code, it is not necessary to use window.open(), the target is already specified in the form.

// Create a form
var mapForm = document.createElement("form");
mapForm.target = "_blank";    
mapForm.method = "POST";
mapForm.action = "abmCatalogs.ftl";

// Create an input
var mapInput = document.createElement("input");
mapInput.type = "text";
mapInput.name = "variable";
mapInput.value = "lalalalala";

// Add the input to the form
mapForm.appendChild(mapInput);

// Add the form to dom
document.body.appendChild(mapForm);

// Just submit
mapForm.submit();

I hope that the below answer may be efficient and also simple:

$content = "The main string to search";
$search = "T";
//For compare the begining string with case insensitive. 
if(stripos($content, $search) === 0) echo 'Yes';
else echo 'No';

//For compare the begining string with case sensitive. 
if(strpos($content, $search) === 0) echo 'Yes';
else echo 'No';

//For compare the ending string with case insensitive. 
if(stripos(strrev($content), strrev($search)) === 0) echo 'Yes';
else echo 'No';

//For compare the ending string with case sensitive. 
if(strpos(strrev($content), strrev($search)) === 0) echo 'Yes';
else echo 'No';

As a summary

import sys
import re

f = sys.argv[1]
find = sys.argv[2]
replace = sys.argv[3]
with open (f, "r") as myfile:
     s=myfile.read()
ret = re.sub(find,replace, s)   # <<< This is where the magic happens
print ret

As per Nawfal's answer, IF statements need to be in a procedure. I found this post that shows a brilliant example of using your script in a procedure while still developing and testing. Basically, you create, call then drop the procedure:

https://gist.github.com/jeremyjarrell/6083251

You could simply use the unary + operator

(+new Date('2012.08.10')/1000).toFixed(0);

http://xkr.us/articles/javascript/unary-add/ - look under Dates.

This is something that should only be done on a per-user basis, not per-repository. If Joe uses emacs, he will want to have emacs backup files ignored, but Betty (who uses vi) will want vi backup files ignored (in many cases, they are similar, but there are about 24,893 common editors in existence and it is pretty ridiculous to try to ignore all of the various backup extensions.)

In other words, do not put anything in .gitignore or in core.excludes in $GIT_DIR/config. Put the info in $HOME/.gitconfig instead (as nunopolonia suggests with --global.) Note that "global" means per-user, not per-system.

If you want configuration across the system for all users (which you don't), you'll need a different mechanism. (Possibly with templates setup prior to initialization of the repository.)

Also, even at the lastest versions of pandas if the column is object type you would have to convert into float first, something like:

df['column_name'].astype(np.float).astype("Int32")

NB: You have to go through numpy float first and then to nullable Int32, for some reason.

The size of the int if it's 32 or 64 depends on your variable, be aware you may loose some precision if your numbers are to big for the format.

In addition to registering a ByteArrayHttpMessageConverter, you may want to use a ResponseEntity instead of @ResponseBody. The following code works for me :

@RequestMapping("/photo2")
public ResponseEntity<byte[]> testphoto() throws IOException {
    InputStream in = servletContext.getResourceAsStream("/images/no_image.jpg");

    final HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.IMAGE_PNG);

    return new ResponseEntity<byte[]>(IOUtils.toByteArray(in), headers, HttpStatus.CREATED);
}

I have been using splitmix64 (pointed in Thomas Mueller's answer) ever since I found this thread. However, I recently stumbled upon Pelle Evensen's rrxmrrxmsx_0, which yielded tremendously better statistical distribution than the original MurmurHash3 finalizer and its successors (splitmix64 and other mixes). Here is the code snippet in C:

#include <stdint.h>

static inline uint64_t ror64(uint64_t v, int r) {
    return (v >> r) | (v << (64 - r));
}

uint64_t rrxmrrxmsx_0(uint64_t v) {
    v ^= ror64(v, 25) ^ ror64(v, 50);
    v *= 0xA24BAED4963EE407UL;
    v ^= ror64(v, 24) ^ ror64(v, 49);
    v *= 0x9FB21C651E98DF25UL;
    return v ^ v >> 28;
}

Pelle also provides an in-depth analysis of the 64-bit mixer used in the final step of MurmurHash3 and the more recent variants.

You can use the .Clear method:

Sheets("Zeros").UsedRange.Clear

Using this you can remove the contents and the formatting of a cell or range without affecting the rest of the worksheet.

You can embed the assembly code in a normal C program. Here's a good introduction. Using the appropriate syntax, you can also tell GCC you want to interact with variables declared in C. The program below instructs gcc that:

• eax shall be foo
• ebx shall be bar
• the value in eax shall be stored in foo after the assembly code executed

\n

int main(void)
{
        int foo = 10, bar = 15;
        __asm__ __volatile__("addl  %%ebx,%%eax"
                             :"=a"(foo)
                             :"a"(foo), "b"(bar)
                             );
        printf("foo+bar=%d\n", foo);
        return 0;
}

>>> x = "2342.34"
>>> float(x)
2342.3400000000001

There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).

From datetime.datetime you already can export to timestamps with method strftime. Following your function example:

import datetime
def UtcNow():
    now = datetime.datetime.utcnow()
    return int(now.strftime("%s"))

If you want microseconds, you need to change the export string and cast to float like: return float(now.strftime("%s.%f"))

White space affects inline elements.

This should not come as a surprise. We see it every day with span, strong and other inline elements. Set the font size to zero to remove the extra margin.

.container {
  font-size: 0px;
  letter-spacing: 0px;
  word-spacing: 0px;
}

.container > div {
  display: inline-block;
  margin: 0px;
  padding: 0px;
  font-size: 15px;
  letter-spacing: 1em;
  word-spacing: 2em;
}

The example would then look like this.

<div class="container">
  <div>First</div>
  <div>Second</div>
</div>

• We can't concatenate a string variable to an integer variable using concat() function because this function only applies to a string, not on a integer. but we can concatenate a string to a number(integer) using + operator.
• As we know, functions are pretty slower than operators. functions needs to pass values to the predefined functions and need to gather the results of the functions. which is slower than doing operations using operators because operators performs operations in-line but, functions used to jump to appropriate memory locations... So, As mentioned in previous answers the other difference is obviously the speed of operation.

var curr_date = d.getDate();

var curr_month = d.getMonth();

var curr_year = d.getFullYear();

document.write(curr_date + "-" + curr_month + "-" + curr_year);

using this you can format date.

Try this method. It should work when field when you want to store image is of type byte. First it creates byte[] for image. Then it saves it to the DB using IDataParameter of type binary.

using System.Drawing;
using System.Drawing.Imaging;
using System.Data;

    public static void PerisitImage(string path, IDbConnection connection)
    {
        using (var command = connection.CreateCommand ())
        {
            Image img = Image.FromFile (path);
            MemoryStream tmpStream = new MemoryStream();
            img.Save (tmpStream, ImageFormat.Png); // change to other format
            tmpStream.Seek (0, SeekOrigin.Begin);
            byte[] imgBytes = new byte[MAX_IMG_SIZE];
            tmpStream.Read (imgBytes, 0, MAX_IMG_SIZE);

            command.CommandText = "INSERT INTO images(payload) VALUES (:payload)";
            IDataParameter par = command.CreateParameter();
            par.ParameterName = "payload";
            par.DbType = DbType.Binary;
            par.Value = imgBytes;
            command.Parameters.Add(par);

Great question - I solved my issue today as follows using Ecilpse:

1. Put your template in the same folder hierarchy as your source code (not in a separate folder hierarchy even if you include it in the build path) as below:

2. In your code simply use the following lines of code (assuming you just want the date to be passed as data):

   VelocityEngine ve = new VelocityEngine();
   ve.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath");
   ve.setProperty("classpath.resource.loader.class", ClasspathResourceLoader.class.getName());
   ve.init();
   VelocityContext context = new VelocityContext();
   context.put("date", getMyTimestampFunction());
   Template t = ve.getTemplate( "templates/email_html_new.vm" );
   StringWriter writer = new StringWriter();
   t.merge( context, writer );
   

See how first we tell VelocityEngine to look in the classpath. Without this it wouldn't know where to look.

I got the same problem since I updated to latest version of Android Studio 0.3.7. So you can try with my stuffs.

Ensure you have updated to latest version Android Support Repository - 3 Android Support Library - 19

As your attachment picture above, you did it already. Then adding the following setting to your build.gradle

dependencies {
    compile 'com.android.support:support-v4:19.0.0'
}

One more thing: Please make sure your Android SDK is targeting to right SDK folder

for(int i = 0; i < getArray.size(); i++){
      Object object = getArray.get(i);
      // now do something with the Object
}

You need to check for the type:

The values can be any of these types: Boolean, JSONArray, JSONObject, Number, String, or the JSONObject.NULL object. [Source]

In your case, the elements will be of type JSONObject, so you need to cast to JSONObject and call JSONObject.names() to retrieve the individual keys.

Simple and Easy , just add following

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

I found a short comparison from MSDN

The .NET Framework Class Library includes four classes named Timer, each of which offers different functionality:

System.Timers.Timer, which fires an event and executes the code in one or more event sinks at regular intervals. The class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.

System.Threading.Timer, which executes a single callback method on a thread pool thread at regular intervals. The callback method is defined when the timer is instantiated and cannot be changed. Like the System.Timers.Timer class, this class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.

System.Windows.Forms.Timer, a Windows Forms component that fires an event and executes the code in one or more event sinks at regular intervals. The component has no user interface and is designed for use in a single-threaded environment.

System.Web.UI.Timer, an ASP.NET component that performs asynchronous or synchronous web page postbacks at a regular interval.

2^31-1 bytes. So, a little less than 2^31-1 characters for varchar(max) and half that for nvarchar(max).

nchar and nvarchar

var formData = new FormData; var arr = ['item1', 'item2', 'item3'];

arr.forEach(item => {
    formData.append(
        "myFile",item
    ); });

(I presume that you've concluded that it's an iptables problem by dropping the firewall completely (iptables -P INPUT ACCEPT; iptables -P OUTPUT ACCEPT; iptables -F) and confirmed that you can connect to the MySQL server from your Windows box?)

Some previous rule in the INPUT table is probably rejecting or dropping the packet. You can get around that by inserting the new rule at the top, although you might want to review your existing rules to see whether that's sensible:

iptables -I INPUT 1 -p tcp --dport 3306 -j ACCEPT

Note that iptables-save won't save the new rule persistently (i.e. across reboots) - you'll need to figure out something else for that. My usual route is to store the iptables-save output in a file (/etc/network/iptables.rules or similar) and then load then with a pre-up statement in /etc/network/interfaces).

Try -

Call CatSubProduktAreakum(Stattyp, Daty + UBound(SubCategories) + 2)

As for the reason, this from MSDN via this question - What does the Call keyword do in VB6?

You are not required to use the Call keyword when calling a procedure. However, if you use the Call keyword to call a procedure that requires arguments, argumentlist must be enclosed in parentheses. If you omit the Call keyword, you also must omit the parentheses around argumentlist. If you use either Call syntax to call any intrinsic or user-defined function, the function's return value is discarded.

try this:

return $this->db->query("
     SELECT * FROM myTable 
     WHERE trans_id IN ( SELECT trans_id FROM myTable WHERE code='B') 
     AND code!='B'
     ")->result_array();

i like to use gawk for running multiple commands on a list, for instance

ls -l | gawk '{system("/path/to/cmd.sh "$1)}'

however the escaping of the escapable characters can get a little hairy.

This works:

ArrayList<String>[] group = new ArrayList[4];

Developing on Windows, I ran into this problem when using git tfs. I solved it this way:

git config --global core.whitespace cr-at-eol

This basically tells Git that an end-of-line CR is not an error. As a result, those annoying ^M characters no longer appear at the end of lines in git diff, git show, etc.

It appears to leave other settings as-is; for instance, extra spaces at the end of a line still show as errors (highlighted in red) in the diff.

(Other answers have alluded to this, but the above is exactly how to set the setting. To set the setting for only one project, omit the --global.)

EDIT:

After many line-ending travails, I've had the best luck, when working on a .NET team, with these settings:

• NO core.eol setting
• NO core.whitespace setting
• NO core.autocrlf setting
• When running the Git installer for Windows, you'll get these three options:
  • Checkout Windows-style, commit Unix-style line endings <-- choose this one
  • Checkout as-is, commit Unix-style line endings
  • Checkout as-is, commit as-is

If you need to use the whitespace setting, you should probably enable it only on a per-project basis if you need to interact with TFS. Just omit the --global:

git config core.whitespace cr-at-eol

If you need to remove some core.* settings, the easiest way is to run this command:

git config --global -e

This opens your global .gitconfig file in a text editor, and you can easily delete the lines you want to remove. (Or you can put '#' in front of them to comment them out.)

You can also use a while loop:

while (true) {
    //your code
}

You need to first add using Microsoft.Win32; to your code page.

Then you can begin to use the Registry classes:

try
{
    using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\\Wow6432Node\\MySQL AB\\MySQL Connector\\Net"))
    {
        if (key != null)
        {
            Object o = key.GetValue("Version");
            if (o != null)
            {
                Version version = new Version(o as String);  //"as" because it's REG_SZ...otherwise ToString() might be safe(r)
                //do what you like with version
            }
        }
    }
}
catch (Exception ex)  //just for demonstration...it's always best to handle specific exceptions
{
    //react appropriately
}

In Google IO 2015, Google announced full NDK integration in Android Studio 1.3.

It is now out of preview, and available to everyone: https://developer.android.com/studio/projects/add-native-code.html

Old answer: Gradle automatically calls ndk-build if you have a jni directory in your project sources.

This is working on Android studio 0.5.9 (canary build).

1. Download the NDK

2. Either add ANDROID_NDK_HOME to your environment variables or add ndk.dir=/path/to/ndk to your local.properties in your Android Studio project. This allows Android studio to run the ndk automatically.

3. Download the latest gradle sample projects to see an example of an ndk project. (They're at the bottom of the page). A good sample project is ndkJniLib.

4. Copy the gradle.build from the NDK sample projects. It'll look something like this. This gradle.build creates a different apk for each architecture. You must select which architecture you want using the build variants pane.

               ndk {
                   abiFilter "x86"
               }
               // this is the flavor part of the version code.
               // It must be higher than the arm one for devices supporting
               // both, as x86 is preferred.
               versionCode = 3
           }
           arm {
               flavorDimension "abi"
               ndk {

               }
               versionCode = 2
           }
           mips {
               flavorDimension "abi"
               ndk {
                   abiFilter "mips"
               }
               versionCode = 1
           }
           fat {
               flavorDimension "abi"
               // fat binary, lowest version code to be
               // the last option
               versionCode = 0
           }
       }
   
       // make per-variant version code
       applicationVariants.all { variant ->
           // get the version code of each flavor
           def apiVersion = variant.productFlavors.get(0).versionCode
           def abiVersion = variant.productFlavors.get(1).versionCode
   
           // set the composite code
           variant.mergedFlavor.versionCode = apiVersion * 1000000 + abiVersion * 100000 + defaultConfig.versionCode
       }
   
   }
   

Note that this will ignore your Android.mk and Application.mk files. As a workaround, you can tell gradle to disable atuomatic ndk-build call, then specify the directory for ndk sources manually.

sourceSets.main {
    jniLibs.srcDir 'src/main/libs' // use the jni .so compiled from the manual ndk-build command
    jni.srcDirs = [] //disable automatic ndk-build call
}

In addition, you'll probably want to call ndk-build in your gradle build script explicitly, because you just disabled the automatic call.

task ndkBuild(type: Exec) {
   commandLine 'ndk-build', '-C', file('src/main/jni').absolutePath
}

tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn ndkBuild
}

You can use view.safeAreaInsets as explained here https://www.raywenderlich.com/174078/auto-layout-visual-format-language-tutorial-2

Something went wrong with your GCC installation. Try reinstalling the it like this:

sudo apt-get install --reinstall g++-5

In Ubuntu the g++ is a dependency package that installs the default version of g++ for your OS version. So simply removing and installing the package again won't work, cause it will install the default version. That's why you need to reinstall.

Note: You can replace the g++-5 with your desired g++ version. To find your current g++ version run this:

g++ --version

Escape the percent sign \% to make it part of your comparison value.

1. Checking for __iter__ works on sequence types, but it would fail on e.g. strings in Python 2. I would like to know the right answer too, until then, here is one possibility (which would work on strings, too):

   from __future__ import print_function
   
   try:
       some_object_iterator = iter(some_object)
   except TypeError as te:
       print(some_object, 'is not iterable')
   

   The iter built-in checks for the __iter__ method or in the case of strings the __getitem__ method.

2. Another general pythonic approach is to assume an iterable, then fail gracefully if it does not work on the given object. The Python glossary:

   Pythonic programming style that determines an object's type by inspection of its method or attribute signature rather than by explicit relationship to some type object ("If it looks like a duck and quacks like a duck, it must be a duck.") By emphasizing interfaces rather than specific types, well-designed code improves its flexibility by allowing polymorphic substitution. Duck-typing avoids tests using type() or isinstance(). Instead, it typically employs the EAFP (Easier to Ask Forgiveness than Permission) style of programming.

   ...

   try:
      _ = (e for e in my_object)
   except TypeError:
      print my_object, 'is not iterable'
   

3. The collections module provides some abstract base classes, which allow to ask classes or instances if they provide particular functionality, for example:

   from collections.abc import Iterable
   
   if isinstance(e, Iterable):
       # e is iterable
   

   However, this does not check for classes that are iterable through __getitem__.

something like

git status | sed -s "s/^.*deleted: //" | xargs git rm 

may do it.

jFrame.getContentPane().setSize(800,400);

So I would advise you to use JPanel embedded in a JFrame and you draw on that JPanel. This would minimize your problem.

JFrame jf = new JFrame();
JPanel jp = new JPanel();
jp.setPreferredSize(new Dimension(400,800));// changed it to preferredSize, Thanks!
jf.getContentPane().add( jp );// adding to content pane will work here. Please read the comment bellow.
jf.pack();

I am reading this from Javadoc

The JFrame class is slightly incompatible with Frame. Like all other JFC/Swing top-level containers, a JFrame contains a JRootPane as its only child. The content pane provided by the root pane should, as a rule, contain all the non-menu components displayed by the JFrame. This is different from the AWT Frame case. For example, to add a child to an AWT frame you'd write:

frame.add(child);

However using JFrame you need to add the child to the JFrame's content pane instead:

frame.getContentPane().add(child);

I had same issue. I changed ANDROID_HOME path on environment variables. And then I copied 'avd' folder, which emulator installed in into 'sdk' folder(ANDROID_HOME path). *** You can find 'avd' folder by clicking 'Show on Disk' in AVD manger. I restarted the emulator and then it is running well now.

This is probably an unusual perspective, but I think that anyone who believes that multiple return statements are to be favoured has never had to use a debugger on a microprocessor that supports only 4 hardware breakpoints. ;-)

While the issues of "arrow code" are completely correct, one issue that seems to go away when using multiple return statements is in the situation where you are using a debugger. You have no convenient catch-all position to put a breakpoint to guarantee that you're going to see the exit and hence the return condition.

If we need only one column to be numeric

yyz$b <- as.numeric(as.character(yyz$b))

But, if all the columns needs to changed to numeric, use lapply to loop over the columns and convert to numeric by first converting it to character class as the columns were factor.

yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))

Both the columns in the OP's post are factor because of the string "n/a". This could be easily avoided while reading the file using na.strings = "n/a" in the read.table/read.csv or if we are using data.frame, we can have character columns with stringsAsFactors=FALSE (the default is stringsAsFactors=TRUE)

Regarding the usage of apply, it converts the dataset to matrix and matrix can hold only a single class. To check the class, we need

lapply(yyz, class)

Or

sapply(yyz, class)

Or check

str(yyz)

Assuming you want to reset your PostgreSQL database and set it back up, use:

heroku apps

to list your applications on Heroku. Find the name of your current application (application_name). Then run

heroku config | grep POSTGRESQL

to get the name of your databases. An example could be

HEROKU_POSTGRESQL_WHITE_URL

Finally, given application_name and database_url, you should run

heroku pg:reset `database_url` --confirm `application_name`
heroku run rake db:migrate
heroku restart

Try to use JSONP in your Ajax call. It will bypass the Same Origin Policy.

http://learn.jquery.com/ajax/working-with-jsonp/

Try example

$.ajax({
    url: "https://api.dailymotion.com/video/x28j5hv?fields=title",

    dataType: "jsonp",
    success: function( response ) {
        console.log( response ); // server response
    }

});

I found 1 solution. if want to translate this kind of SQL (left join) into Linq Entity...

SQL:

SELECT * FROM [JOBBOOKING] AS [t0]
LEFT OUTER JOIN [REFTABLE] AS [t1] ON ([t0].[trxtype] = [t1].[code])
                                  AND ([t1]. [reftype] = "TRX")

LINQ:

from job in JOBBOOKINGs
join r in (from r1 in REFTABLEs where r1.Reftype=="TRX" select r1) 
          on job.Trxtype equals r.Code into join1
from j in join1.DefaultIfEmpty()
select new
{
   //cols...
}

I have tried all solution. The -lopencv_core -lopencv_imgproc -lopencv_highgui in comments solved my problem. And know my command line looks like this in geany:

g++ -lopencv_core -lopencv_imgproc -lopencv_highgui  -o "%e" "%f"

When I build:

g++ -lopencv_core -lopencv_imgproc -lopencv_highgui  -o "opencv" "opencv.cpp" (in directory: /home/fedora/Desktop/Implementations)

The headers are:

#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"

The alternative, if you don't want to install libjpeg:

CFLAGS="--disable-jpeg" pip install pillow

From https://pillow.readthedocs.io/en/3.0.0/installation.html#external-libraries

In a more basic way to explain: An interface is sort of like an empty muffin pan. It's a class file with a set of method definitions that have no code.

An abstract class is the same thing, but not all functions need to be empty. Some can have code. It's not strictly empty.

Why differentiate: There's not much practical difference in Python, but on the planning level for a large project, it could be more common to talk about interfaces, since there's no code. Especially if you're working with Java programmers who are accustomed to the term.

Just call the "type" built in using three parameters, like this:

ClassName = type("ClassName", (Base1, Base2,...), classdictionary)

update as stated in the comment bellow this is not the answer to this question at all. I will keep it undeleted, since there are hints some people get here trying to dynamically create classes - which is what the line above does.

To create an object of a class one has a reference too, as put in the accepted answer, one just have to call the class:

instance = ClassObject()

The mechanism for instantiation is thus:

Python does not use the new keyword some languages use - instead it's data model explains the mechanism used to create an instantance of a class when it is called with the same syntax as any other callable:

Its class' __call__ method is invoked (in the case of a class, its class is the "metaclass" - which is usually the built-in type). The normal behavior of this call is to invoke the (pseudo) static __new__ method on the class being instantiated, followed by its __init__. The __new__ method is responsible for allocating memory and such, and normally is done by the __new__ of object which is the class hierarchy root.

So calling ClassObject() invokes ClassObject.__class__.call() (which normally will be type.__call__) this __call__ method will receive ClassObject itself as the first parameter - a Pure Python implementation would be like this: (the cPython version is of course, done in C, and with lots of extra code for cornercases and optimizations)

class type:
    ...
    def __call__(cls, *args, **kw):
          constructor = getattr(cls, "__new__")
          instance = constructor(cls) if constructor is object.__new__ else constructor(cls, *args, **kw)
          instance.__init__(cls, *args, **kw)
          return instance

(I don't recall seeing on the docs the exact justification (or mechanism) for suppressing extra parameters to the root __new__ and passing it to other classes - but it is what happen "in real life" - if object.__new__ is called with any extra parameters it raises a type error - however, any custom implementation of a __new__ will get the extra parameters normally)

you can use the zenity to displays the query output as html table.

• first implement bash script with following code:

  cat > '/tmp/sql.op'; zenity --text-info --html --filename='/tmp/sql.op';

  save it like mypager.sh

• Then export the environment variable PAGER by set full path of the script as value.

  for example:- export PAGER='/path/mypager.sh'

• Then login to the psql program then execute the command \H

• And finally execute any query,the tabled output will displayed in the zenity in html table format.

and tests whether both expressions are logically True while & (when used with True/False values) tests if both are True.

In Python, empty built-in objects are typically treated as logically False while non-empty built-ins are logically True. This facilitates the common use case where you want to do something if a list is empty and something else if the list is not. Note that this means that the list [False] is logically True:

>>> if [False]:
...    print 'True'
...
True

So in Example 1, the first list is non-empty and therefore logically True, so the truth value of the and is the same as that of the second list. (In our case, the second list is non-empty and therefore logically True, but identifying that would require an unnecessary step of calculation.)

For example 2, lists cannot meaningfully be combined in a bitwise fashion because they can contain arbitrary unlike elements. Things that can be combined bitwise include: Trues and Falses, integers.

NumPy objects, by contrast, support vectorized calculations. That is, they let you perform the same operations on multiple pieces of data.

Example 3 fails because NumPy arrays (of length > 1) have no truth value as this prevents vector-based logic confusion.

Example 4 is simply a vectorized bit and operation.

Bottom Line

• If you are not dealing with arrays and are not performing math manipulations of integers, you probably want and.

• If you have vectors of truth values that you wish to combine, use numpy with &.

One possible way is to use .map() method:

var all = $(".mbox").map(function() {
    return this.innerHTML;
}).get();

console.log(all.join());

DEMO: http://jsfiddle.net/Y4bHh/

N.B. Please don't use document.write. For testing purposes console.log is the best way to go.

Using PyV8, I can do this. However, I have to replace document.write with return because there's no DOM and therefore no document.

import PyV8
ctx = PyV8.JSContext()
ctx.enter()

js = """
function escramble_758(){
var a,b,c
a='+1 '
b='84-'
a+='425-'
b+='7450'
c='9'
document.write(a+c+b)
}
escramble_758()
"""

print ctx.eval(js.replace("document.write", "return "))

Or you could create a mock document object

class MockDocument(object):

    def __init__(self):
        self.value = ''

    def write(self, *args):
        self.value += ''.join(str(i) for i in args)


class Global(PyV8.JSClass):
    def __init__(self):
        self.document = MockDocument()

scope = Global()
ctx = PyV8.JSContext(scope)
ctx.enter()
ctx.eval(js)
print scope.document.value

To hopefully make all of this a little more concrete, here’s a worked example of configuring a Spark app to use as much of the cluster as possible: Imagine a cluster with six nodes running NodeManagers, each equipped with 16 cores and 64GB of memory. The NodeManager capacities, yarn.nodemanager.resource.memory-mb and yarn.nodemanager.resource.cpu-vcores, should probably be set to 63 * 1024 = 64512 (megabytes) and 15 respectively. We avoid allocating 100% of the resources to YARN containers because the node needs some resources to run the OS and Hadoop daemons. In this case, we leave a gigabyte and a core for these system processes. Cloudera Manager helps by accounting for these and configuring these YARN properties automatically.

The likely first impulse would be to use --num-executors 6 --executor-cores 15 --executor-memory 63G. However, this is the wrong approach because:

63GB + the executor memory overhead won’t fit within the 63GB capacity of the NodeManagers. The application master will take up a core on one of the nodes, meaning that there won’t be room for a 15-core executor on that node. 15 cores per executor can lead to bad HDFS I/O throughput.

A better option would be to use --num-executors 17 --executor-cores 5 --executor-memory 19G. Why?

This config results in three executors on all nodes except for the one with the AM, which will have two executors. --executor-memory was derived as (63/3 executors per node) = 21. 21 * 0.07 = 1.47. 21 – 1.47 ~ 19.

The explanation was given in an article in Cloudera's blog, How-to: Tune Your Apache Spark Jobs (Part 2).

You're not running a module -- you're running subroutines/functions that happen to be stored in modules.

If you put the code in a standalone module and don't specify scope in the definitions of your subroutines/functions, they will be public by default, and callable from anywhere within your application. This means that you can call them with RunCode in a macro, from the class modules of forms/reports, from standalone class modules, or for the functions, from SQL (with some caveats).

Given that you were trying to implement in VBA something that you felt was too complicated for SQL, SQL is the likely context in which you want to execute the code. So, you should just be able to call your function within the SQL statement:

  SELECT MyTable.PersonID, MyTable.FirstName, MyTable.LastName, FormatAddress([Address], [City], [State], [Zip], [Country]) As Address
  FROM MyTable;

That SQL calls a public function called FormatAddress() that takes as arguments the components of an address and formats them appropriately. It's a trivial example as you likely would not need a VBA function for that purpose, but the point is that this is how you call functions from within a SQL statement.

Subroutines (i.e., code that returns no value) are not callable from within SQL statements.

    void input_from_key_board(int &ri, int &ci)
{
    char ch = 'x';
    if (_kbhit())
    {
        ch = _getch();
        if (ch == -32)
        {
            ch = _getch();
            switch (ch)
            {
            case 72: { ri--; break; }
            case 80: { ri++; break; }
            case 77: { ci++; break; }
            case 75: { ci--; break; }

            }
        }
        else if (ch == '\r'){ gotoRowCol(ri++, ci -= ci); }
        else if (ch == '\t'){ gotoRowCol(ri, ci += 5); }
        else if (ch == 27) { system("ipconfig"); }
        else if (ch == 8){ cout << " "; gotoRowCol(ri, --ci); if (ci <= 0)gotoRowCol(ri--, ci); }
        else { cout << ch; gotoRowCol(ri, ci++); }
        gotoRowCol(ri, ci);
    }
}

use the following commands instead:

ALTER TABLE table_name DISABLE TRIGGER tr_name

ALTER TABLE table_name ENABLE TRIGGER tr_name

When possible, I debug using M-x pdb in emacs for source level debugging.

To access the properties of an object without knowing the names of those properties you can use a for ... in loop:

for(key in data) {
    if(data.hasOwnProperty(key)) {
        var value = data[key];
        //do something with value;
    }
}

Technically, Breadth-first search (BFS) by itself does not let you find the shortest path, simply because BFS is not looking for a shortest path: BFS describes a strategy for searching a graph, but it does not say that you must search for anything in particular.

Dijkstra's algorithm adapts BFS to let you find single-source shortest paths.

In order to retrieve the shortest path from the origin to a node, you need to maintain two items for each node in the graph: its current shortest distance, and the preceding node in the shortest path. Initially all distances are set to infinity, and all predecessors are set to empty. In your example, you set A's distance to zero, and then proceed with the BFS. On each step you check if you can improve the distance of a descendant, i.e. the distance from the origin to the predecessor plus the length of the edge that you are exploring is less than the current best distance for the node in question. If you can improve the distance, set the new shortest path, and remember the predecessor through which that path has been acquired. When the BFS queue is empty, pick a node (in your example, it's E) and traverse its predecessors back to the origin. This would give you the shortest path.

If this sounds a bit confusing, wikipedia has a nice pseudocode section on the topic.
