I was just playing around with this same subject, which is the fastest way to access the pixels. I currently know of two ways for doing this:

1. Using BufferedImage's getRGB() method as described in @tskuzzy's answer.

2. By accessing the pixels array directly using:

   byte[] pixels = ((DataBufferByte) bufferedImage.getRaster().getDataBuffer()).getData();
   

If you are working with large images and performance is an issue, the first method is absolutely not the way to go. The getRGB() method combines the alpha, red, green and blue values into one int and then returns the result, which in most cases you'll do the reverse to get these values back.

The second method will return the red, green and blue values directly for each pixel, and if there is an alpha channel it will add the alpha value. Using this method is harder in terms of calculating indices, but is much faster than the first approach.

In my application I was able to reduce the time of processing the pixels by more than 90% by just switching from the first approach to the second!

Here is a comparison I've setup to compare the two approaches:

BUILD SUCCESSFUL (total time: 3 minutes 10 seconds)

If you've just added the select option to a form and you wish to trigger the change event, I've found a setTimeout is required otherwise jQuery doesn't pick up the newly added select box:

window.setTimeout(function() { jQuery('.languagedisplay').change();}, 1);

This is working fine for me:

ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
            int rawContactInsertIndex = ops.size();

            ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI)
                    .withValue(RawContacts.ACCOUNT_TYPE, null)
                    .withValue(RawContacts.ACCOUNT_NAME, null).build());
            ops.add(ContentProviderOperation
                    .newInsert(Data.CONTENT_URI)
                    .withValueBackReference(Data.RAW_CONTACT_ID,rawContactInsertIndex)
                    .withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE)
                    .withValue(StructuredName.DISPLAY_NAME, "Vikas Patidar") // Name of the person
                    .build());
            ops.add(ContentProviderOperation
                    .newInsert(Data.CONTENT_URI)
                    .withValueBackReference(
                            ContactsContract.Data.RAW_CONTACT_ID,   rawContactInsertIndex)
                    .withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE)
                    .withValue(Phone.NUMBER, "9999999999") // Number of the person
                    .withValue(Phone.TYPE, Phone.TYPE_MOBILE).build()); // Type of mobile number                    
            try
            {
                ContentProviderResult[] res = getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

1. Set var step=1 as global variable by putting it above the function call
2. put semicolons

It will look like this

<head>
<script type="text/javascript">
var image1 = new Image()
image1.src = "images/pentagg.jpg"
var image2 = new Image()
image2.src = "images/promo.jpg"
</script>
</head>
<body>
<p><img src="images/pentagg.jpg" width="500" height="300" name="slide" /></p>
<script type="text/javascript">
        var step=1;
        function slideit()
        {
            document.images.slide.src = eval("image"+step+".src");
            if(step<2)
                step++;
            else
                step=1;
            setTimeout("slideit()",2500);
        }
        slideit();
</script>
</body>

To find all types in an assembly that implement IFoo interface:

var results = from type in someAssembly.GetTypes()
              where typeof(IFoo).IsAssignableFrom(type)
              select type;

Note that Ryan Rinaldi's suggestion was incorrect. It will return 0 types. You cannot write

where type is IFoo

because type is a System.Type instance, and will never be of type IFoo. Instead, you check to see if IFoo is assignable from the type. That will get your expected results.

Also, Adam Wright's suggestion, which is currently marked as the answer, is incorrect as well, and for the same reason. At runtime, you'll see 0 types come back, because all System.Type instances weren't IFoo implementors.

If you're using React Native, you can use the array notation:

Check out my detailed blog post about this.

I write a function support dynamic variable string append, like PHP str append: str + str + ... etc.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdarg.h>

int str_append(char **json, const char *format, ...)
{
    char *str = NULL;
    char *old_json = NULL, *new_json = NULL;

    va_list arg_ptr;
    va_start(arg_ptr, format);
    vasprintf(&str, format, arg_ptr);

    // save old json
    asprintf(&old_json, "%s", (*json == NULL ? "" : *json));

    // calloc new json memory
    new_json = (char *)calloc(strlen(old_json) + strlen(str) + 1, sizeof(char));

    strcat(new_json, old_json);
    strcat(new_json, str);

    if (*json) free(*json);
    *json = new_json;

    free(old_json);
    free(str);

    return 0;
}

int main(int argc, char *argv[])
{
    char *json = NULL;

    str_append(&json, "name: %d, %d, %d", 1, 2, 3);
    str_append(&json, "sex: %s", "male");
    str_append(&json, "end");
    str_append(&json, "");
    str_append(&json, "{\"ret\":true}");

    int i;
    for (i = 0; i < 10; i++) {
        str_append(&json, "id-%d", i);
    }

    printf("%s\n", json);

    if (json) free(json);

    return 0;
}

Generally speaking, you can update your index mapping using the put mapping api (reference here) :

curl -XPUT 'http://localhost:9200/advert_index/_mapping/advert_type' -d '
{
    "advert_type" : {
        "properties" : {

          //your new mapping properties

        }
    }
}
'

It's especially useful for adding new fields. However, in your case, you will try to change the location type, which will cause a conflict and prevent the new mapping from being used.

You could use the put mapping api to add another property containing the location as a lat/lon array, but you won't be able to update the previous location field itself.

Finally, you will have to reindex your data for your new mapping to be taken into account.

The best solution would really be to create a new index.

If your problem with creating another index is downtime, you should take a look at aliases to make things go smoothly.

You can also try linq.js

In linq.js your

selectedFruits.select(fruit=>fruit.id);

will be

Enumerable.From(selectedFruits).Select(function (fruit) { return fruit.id;  });

The best way is set this two events to all of windows of your app:

GotKeyboardFocus
LostKeyboardFocus

in this way:

WiondowOfMyApp_GotKeyboardFocus(object sender, System.Windows.Input.KeyboardFocusChangedEventArgs e)
{
    windowThatShouldBeTopMost.TopMost = true;
}

WiondowOfMyApp_LostKeyboardFocus(object sender, System.Windows.Input.KeyboardFocusChangedEventArgs e)
{
    windowThatShouldBeTopMost.TopMost = false;
}

• and surely all of the windows that you wanted to be top, should be accessible from other windows of your app. in my case I have a base window and another some windows that should be top of my base window, so this was not bad to my base window has instance of each another windows.

You can use sys.exit() to exit from the middle of the main function.

However, I would recommend not doing any logic there. Instead, put everything in a function, and call that from __main__ - then you can use return as normal.

With the parentheses:

setTimeout("alertMsg()", 3000); // It work, here it treat as a function

Without the quotes and the parentheses:

setTimeout(alertMsg, 3000); // It also work, here it treat as a function

And the third is only using quotes:

setTimeout("alertMsg", 3000); // It not work, here it treat as a string

function alertMsg1() {_x000D_
        alert("message 1");_x000D_
    }_x000D_
    function alertMsg2() {_x000D_
        alert("message 2");_x000D_
    }_x000D_
    function alertMsg3() {_x000D_
        alert("message 3");_x000D_
    }_x000D_
    function alertMsg4() {_x000D_
        alert("message 4");_x000D_
    }_x000D_
_x000D_
    // this work after 2 second_x000D_
    setTimeout(alertMsg1, 2000);_x000D_
_x000D_
    // This work immediately_x000D_
    setTimeout(alertMsg2(), 4000);_x000D_
_x000D_
    // this fail_x000D_
    setTimeout('alertMsg3', 6000);_x000D_
_x000D_
    // this work after 8second_x000D_
    setTimeout('alertMsg4()', 8000);

In the above example first alertMsg2() function call immediately (we give the time out 4S but it don't bother) after that alertMsg1() (A time wait of 2 Second) then alertMsg4() (A time wait of 8 Second) but the alertMsg3() is not working because we place it within the quotes without parties so it is treated as a string.

I tested and used this command in kafka confluent V4.0.0 and apache kafka V 1.0.0 and 1.0.1

/opt/kafka/confluent-4.0.0/bin/kafka-configs --zookeeper XX.XX.XX.XX:2181 --entity-type topics --entity-name test --alter --add-config  retention.ms=55000

test is the topic name.

I think it works well in other versions too

You can also used like this

<a href="<?php echo 'index.php'; ?>">Index Page</a>
<a href="<?php echo 'page2.php'; ?>">Page 2</a>

According to the docker-compose reference,

Ports is defined as:

Expose ports. Either specify both ports (HOST:CONTAINER), or just the container port (a random host port will be chosen).

• Ports mentioned in docker-compose.yml will be shared among different services started by the docker-compose.
• Ports will be exposed to the host machine to a random port or a given port.

My docker-compose.yml looks like:

mysql:
  image: mysql:5.7
  ports:
    - "3306"

If I do docker-compose ps, it will look like:

  Name                     Command               State            Ports
-------------------------------------------------------------------------------------
  mysql_1       docker-entrypoint.sh mysqld      Up      0.0.0.0:32769->3306/tcp

Expose is defined as:

Expose ports without publishing them to the host machine - they’ll only be accessible to linked services. Only the internal port can be specified.

Ports are not exposed to host machines, only exposed to other services.

mysql:
  image: mysql:5.7
  expose:
    - "3306"

If I do docker-compose ps, it will look like:

  Name                  Command             State    Ports
---------------------------------------------------------------
 mysql_1      docker-entrypoint.sh mysqld   Up      3306/tcp

Edit

In recent versions of Docker, expose doesn't have any operational impact anymore, it is just informative. (see also)

On my 10.6 system:

vhosts folder:
 owner:root
 group:wheel
 permissions:755

vhost.conf files:
 owner:root
 group:wheel
 permissions:644

Try this:

word = "habit"
findchar = 'b"
replacechar = ""
charactercount = len(word) - len(replace(word,findchar,replacechar))

def addition(a, b): return a + b

def subtraction(a, b): return a - b

def multiplication(a, b): return a * b

def division(a, b): return a / b

keepProgramRunning = True

print "Welcome to the Calculator!"

while keepProgramRunning:
print "Please choose what you'd like to do:"

print "0: Addition"
print "1: Subtraction"
print "2: Multiplication"
print "3: Division"
print "4: Quit Application"



#Capture the menu choice.
choice = raw_input()    

if choice == "0":
    numberA = input("Enter your first number: ")
    numberB = input("Enter your second number: ")
    print "Your result is: " + str(addition(numberA, numberB)) + "\n"
elif choice == "1":
    numberA = input("Enter your first number: ")
    numberB = input("Enter your second number: ")
    print "Your result is: " + str(subtraction(numberA, numberB)) + "\n"
elif choice == "2":
    numberA = input("Enter your first number: ")
    numberB = input("Enter your second number: ")
    print "Your result is: " + str(multiplication(numberA, numberB)) + "\n"

    numberA = input("Enter your first number: ")
    numberB = input("Enter your second number: ")
    print "Your result is: " + str(division(numberA, numberB)) + "\n"
elif choice == "4":
    print "Bye!"
    keepProgramRunning = False
else:
    print "Please choose a valid option."
    print "\n"

You could also have a union of the blank select with the select that has content:

select '' value, '' name
union
select value, name from mytable

This might not directly answer your question but for the sake of those that come with states like the below

 state = {
    currentstate:[
     {
    id: 1 ,
    firstname: 'zinani',
    sex: 'male'

     }
    ]

 }

Solution

const new_value = {
    id: 2 ,
    firstname: 'san',
    sex: 'male'

     }

Replace the current state with the new value

 this.setState({ currentState: [...this.state.currentState, new_array] })

If on your system User Control Account is Off then you can run the XAMPP as Administrator and check the boxes for run as service.

And if on your system User Control Account is On then it may not work. You have go to Configuration files and manually install as a service or run apache_installservice.bat for Apache and mysql_installservice.bat for MySQL at the path

1. C:\xampp\apache
2. C:\xampp\mysql

if path is the default path.

How about this one:

select 
    from_unixtime(unix_timestamp(timestamp) - unix_timestamp(timestamp) mod 300) as ts,  
    sum(value)
from group_interval 
group by ts 
order by ts
;

This one is noteworthy as well

<div ng-repeat="post in posts" ng-if="post.type=='article'">
  <h1>{{post.title}}</h1>
</div>

Assign opacity 1.0 to the child recursively with:

div > div { opacity: 1.0 }

Example:

div.x { opacity: 0.5 }_x000D_
div.x > div.x { opacity: 1.0 }

<div style="background-color: #f00; padding:20px;">_x000D_
  <div style="background-color: #0f0; padding:20px;">_x000D_
    <div style="background-color: #00f; padding:20px;">_x000D_
      <div style="background-color: #000; padding:20px; color:#fff">_x000D_
         Example Text - No opacity definition_x000D_
      </div>_x000D_
    </div>  _x000D_
  </div>_x000D_
</div>_x000D_
<div style="opacity:0.5; background-color: #f00; padding:20px;">_x000D_
  <div style="opacity:0.5; background-color: #0f0; padding:20px;">_x000D_
    <div style="opacity:0.5; background-color: #00f; padding:20px;">_x000D_
      <div style="opacity:0.5; background-color: #000; padding:20px; color:#fff">_x000D_
        Example Text - 50% opacity inherited_x000D_
      </div>_x000D_
    </div>  _x000D_
  </div>_x000D_
</div>_x000D_
<div class="x" style="background-color: #f00; padding:20px;">_x000D_
  <div class="x" style="background-color: #0f0; padding:20px;">_x000D_
    <div class="x" style="background-color: #00f; padding:20px;">_x000D_
      <div class="x" style="background-color: #000; padding:20px; color:#fff">_x000D_
         Example Text - 50% opacity not inherited_x000D_
      </div>_x000D_
    </div>  _x000D_
  </div>_x000D_

</div>

In fact I would not use any REDIM, nor a loop for transferring data from sheet to array:

dim arOne()
arOne = range("A2:F1000")

or even

arOne = range("A2").CurrentRegion

and that's it, your array is filled much faster then with a loop, no redim.

Just to that :)

$('#form-edit').trigger("reset");
$('#form-edit').find('select').each(function(){
  $(this).change();
});

Try this below code it is also works well in angular 2

<span>{{current_date | date: 'yyyy-MM-dd'}}</span>

I was also following the instructions on http://developer.android.com/training/basics/actionbar/setting-up.html

and even though I did everything in the tutorial, as soon as "extends Action" is changed to "extends ActionBarActivity" all sorts of errors appear in Eclipse, including the "ActionBarActivitycannot be resolved to a type"

None of the above solutions worked for me, but what did work is adding this line to the top:

import android.support.v7.app.ActionBarActivity;

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

In my case it was because I didn't connect to databases yet when first opened solution. click connection manager tab, establish connection to every datasource in that tab, run project

I've been using this guy to do the job: https://github.com/weichx/cerialize

It's very simple yet powerful. It supports:

• Serialization & deserialization of a whole tree of objects.
• Persistent & transient properties on the same object.
• Hooks to customize the (de)serialization logic.
• It can (de)serialize into an existing instance (great for Angular) or generate new instances.
• etc.

Example:

class Tree {
  @deserialize public species : string; 
  @deserializeAs(Leaf) public leafs : Array<Leaf>;  //arrays do not need extra specifications, just a type.
  @deserializeAs(Bark, 'barkType') public bark : Bark;  //using custom type and custom key name
  @deserializeIndexable(Leaf) public leafMap : {[idx : string] : Leaf}; //use an object as a map
}

class Leaf {
  @deserialize public color : string;
  @deserialize public blooming : boolean;
  @deserializeAs(Date) public bloomedAt : Date;
}

class Bark {
  @deserialize roughness : number;
}

var json = {
  species: 'Oak',
  barkType: { roughness: 1 },
  leafs: [ {color: 'red', blooming: false, bloomedAt: 'Mon Dec 07 2015 11:48:20 GMT-0500 (EST)' } ],
  leafMap: { type1: { some leaf data }, type2: { some leaf data } }
}
var tree: Tree = Deserialize(json, Tree);

As written before, the efficiency basically depends on what one is optimizing for.

When optiming for lines of code, or just working in environment without fully-equipped standard library one quick and dirty option could be:

// makes a number from two ascii hexa characters
int ahex2int(char a, char b){

    a = (a <= '9') ? a - '0' : (a & 0x7) + 9;
    b = (b <= '9') ? b - '0' : (b & 0x7) + 9;

    return (a << 4) + b;
}

To understand this, you must take a step back. In OO, the customer owns the orders (orders are a list in the customer object). There can't be an order without a customer. So the customer seems to be the owner of the orders.

But in the SQL world, one item will actually contain a pointer to the other. Since there is 1 customer for N orders, each order contains a foreign key to the customer it belongs to. This is the "connection" and this means the order "owns" (or literally contains) the connection (information). This is exactly the opposite from the OO/model world.

This may help to understand:

public class Customer {
     // This field doesn't exist in the database
     // It is simulated with a SQL query
     // "OO speak": Customer owns the orders
     private List<Order> orders;
}

public class Order {
     // This field actually exists in the DB
     // In a purely OO model, we could omit it
     // "DB speak": Order contains a foreign key to customer
     private Customer customer;
}

The inverse side is the OO "owner" of the object, in this case the customer. The customer has no columns in the table to store the orders, so you must tell it where in the order table it can save this data (which happens via mappedBy).

Another common example are trees with nodes which can be both parents and children. In this case, the two fields are used in one class:

public class Node {
    // Again, this is managed by Hibernate.
    // There is no matching column in the database.
    @OneToMany(cascade = CascadeType.ALL) // mappedBy is only necessary when there are two fields with the type "Node"
    private List<Node> children;

    // This field exists in the database.
    // For the OO model, it's not really necessary and in fact
    // some XML implementations omit it to save memory.
    // Of course, that limits your options to navigate the tree.
    @ManyToOne
    private Node parent;
}

This explains for the "foreign key" many-to-one design works. There is a second approach which uses another table to maintain the relations. That means, for our first example, you have three tables: The one with customers, the one with orders and a two-column table with pairs of primary keys (customerPK, orderPK).

This approach is more flexible than the one above (it can easily handle one-to-one, many-to-one, one-to-many and even many-to-many). The price is that

• it's a bit slower (having to maintain another table and joins uses three tables instead of just two),
• the join syntax is more complex (which can be tedious if you have to manually write many queries, for example when you try to debug something)
• it's more error prone because you can suddenly get too many or too few results when something goes wrong in the code which manages the connection table.

That's why I rarely recommend this approach.

You should use Javascript animations for this - it is not possible in pure CSS, because you can't know the height of any element. Follow the instructions it has for you about javascript animation implementation, and copy slideUp and slideDown from jQuery's source.

You may try the following code for capturing the closing event for any item : page, dialog etc.

$("#dialog").live('pagehide', function(event, ui) {
      $(this).hide();
});

Edit:
In 2.7 / 3.2 there is a new writeheader() method. Also, John Machin's answer provides a simpler method of writing the header row.
Simple example of using the writeheader() method now available in 2.7 / 3.2:

from collections import OrderedDict
ordered_fieldnames = OrderedDict([('field1',None),('field2',None)])
with open(outfile,'wb') as fou:
    dw = csv.DictWriter(fou, delimiter='\t', fieldnames=ordered_fieldnames)
    dw.writeheader()
    # continue on to write data

Instantiating DictWriter requires a fieldnames argument.
From the documentation:

The fieldnames parameter identifies the order in which values in the dictionary passed to the writerow() method are written to the csvfile.

Put another way: The Fieldnames argument is required because Python dicts are inherently unordered.
Below is an example of how you'd write the header and data to a file.
Note: with statement was added in 2.6. If using 2.5: from __future__ import with_statement

with open(infile,'rb') as fin:
    dr = csv.DictReader(fin, delimiter='\t')

# dr.fieldnames contains values from first row of `f`.
with open(outfile,'wb') as fou:
    dw = csv.DictWriter(fou, delimiter='\t', fieldnames=dr.fieldnames)
    headers = {} 
    for n in dw.fieldnames:
        headers[n] = n
    dw.writerow(headers)
    for row in dr:
        dw.writerow(row)

As @FM mentions in a comment, you can condense header-writing to a one-liner, e.g.:

with open(outfile,'wb') as fou:
    dw = csv.DictWriter(fou, delimiter='\t', fieldnames=dr.fieldnames)
    dw.writerow(dict((fn,fn) for fn in dr.fieldnames))
    for row in dr:
        dw.writerow(row)

Take a look at Behaviour of increment and decrement operators in Python for an explanation of why this doesn't work.

Python doesn't really have ++ and --, and I personally never felt it was such a loss.

I prefer functions with clear names to operators with non-always clear semantics (hence the classic interview question about ++x vs. x++ and the difficulties of overloading it). I've also never been a huge fan of what post-incrementation does for readability.

You could always define some wrapper class (like accumulator) with clear increment semantics, and then do something like x.increment() or x.incrementAndReturnPrev()

Assuming the value is nvarchar type for that only we are using N''

There is an attribute called android:weightSum.

You can set android:weightSum="2" in the parent linear_layout and android:weight="1" in the inner linear_layout.

Remember to set the inner linear_layout to fill_parent so weight attribute can work as expected.

Btw, I don't think its necesary to add a second view, altough I haven't tried. :)

<LinearLayout
    android:layout_height="fill_parent"
    android:layout_width="fill_parent"
    android:weightSum="2">

    <LinearLayout
        android:layout_height="fill_parent"
        android:layout_width="fill_parent"
        android:layout_weight="1">
    </LinearLayout>

</LinearLayout>

For replace you can use vbCrLf:

Replace(string, vbCrLf, "")

You can also use chr(13)+chr(10).

I seem to remember in some odd cases that chr(10) comes before chr(13).

This answer uses the DataFrame.filter method to do this without list comprehension:

import pandas as pd

data = {'spike-2': [1,2,3], 'hey spke': [4,5,6]}
df = pd.DataFrame(data)

print(df.filter(like='spike').columns)

Will output just 'spike-2'. You can also use regex, as some people suggested in comments above:

print(df.filter(regex='spike|spke').columns)

Will output both columns: ['spike-2', 'hey spke']

Do this:

<video style="display:block; margin: 0 auto;" controls>....</video>

Works perfect! :D

Asset.objects.filter( project__name__contains="Foo" )

}

/* print some text */
const char *text = "Write this to the file";
fprintf(f, "Some text: %s\n", text);

/* print integers and floats */
int i = 1;
float py = 3.1415927;
fprintf(f, "Integer: %d, float: %f\n", i, py);

/* printing single chatacters */
char c = 'A';
fprintf(f, "A character: %c\n", c);

fclose(f);

Try the :lt selector: http://docs.jquery.com/Selectors/lt#index

$('a:lt(20)');

I have to answer, too. The JIT generates tables together with the code from it's static analysis of variable usage. Those table entries are the "GC-Roots" in the current stack frame. As the instruction pointer advances, those table entries become invalid and so ready for garbage collection. Therefore: If it is a scoped variable, you don't need to set it to null - the GC will collect the object. If it is a member or a static variable, you have to set it to null

The inflect package can do this.

https://pypi.python.org/pypi/inflect

$ pip install inflect

and then:

>>>import inflect
>>>p = inflect.engine()
>>>p.number_to_words(99)
ninety-nine

Yet another way to fix this on Mac OS X with Homebrew installed, is this:

brew install Caskroom/cask/java

just use scrollTo plugin

$("document").ready(function(){
  $(window).scrollTo("#div")
})

folks, I got this Bootstrap dropdown working. I modified the click event slightly in order to keep the currently-selected image. And as you see, the USD currency is the default selected :

<div class="btn-group" style="margin:10px;">    <!-- CURRENCY, BOOTSTRAP DROPDOWN -->
                <!--<a class="btn btn-primary" href="javascript:void(0);">Currency</a>-->                    
                <a class="btn btn-primary dropdown-toggle" data-toggle="dropdown" href="#"><img src="../../Images/flag-usd-small.png"> USD <span class="caret"></span></a>
                <ul class="dropdown-menu">
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-aud-small.png" /> AUD</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-cad-small.png" /> CAD</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-cny-small.png" /> CNY</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-gbp-small.png" /> GBP</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-usd-small.png" /> USD</a>
                    </li>
                </ul>
            </div>


/* BOOTSTRAP DROPDOWN MENU - Update selected item text and image */
$(".dropdown-menu li a").click(function () {
    var selText = $(this).text();
    var imgSource = $(this).find('img').attr('src');
    var img = '<img src="' + imgSource + '"/>';        
    $(this).parents('.btn-group').find('.dropdown-toggle').html(img + ' ' + selText + ' <span class="caret"></span>');
});

Here is an example that replaces all instances of 1 or more white space characters in a column with an underscore using regular expression -

select distinct on (pd)
regexp_replace(rndc.pd, '\\s+', '_','g') as pd
from rndc14_ndc_mstr rndc;

Another option that is pretty short:

<script type="text/javascript">
$.ajax({
  url: "/js/partials",
  success: function(data){
     $(data).find('a:contains(.js)').each(function(){
        // will loop through 
        var partial= $(this).attr("href");
        $.getScript( "/js/partials/" + partial, function( data, textStatus, jqxhr ) {});
     });
  }
});
</script>

Try to make your javascript unobtrusive :

• you should use a real link in href attribute
• and add a listener on click event to handle ajax

You can generate a data URI. However, there are browser-specific limitations.

I found an answer here well practiced, but it was still necessary to add a delay

Create the following directive:

angular.module('MyApp').directive('emitLastRepeaterElement', function() {
return function(scope) {
    if (scope.$last){
        scope.$emit('LastRepeaterElement');
    }
}; });

Add it to your repeater as an attribute, like this:

<div ng-repeat="item in items" emit-last-repeater-element></div>

According to Radu,:

$scope.eventoSelecionado.internamento_evolucoes.forEach(ie => {mycode});

For me it works, but I still need to add a setTimeout

$scope.eventoSelecionado.internamento_evolucoes.forEach(ie => {
setTimeout(function() { 
    mycode
}, 100); });

unsigned is used when ur value must be positive, no negative value here, if signed for int range -32768 to +32767 if unsigned for int range 0 to 65535

res is an HttpResponse object which extends from OutgoingMessage. res.send calls res.end which is implemented by OutgoingMessage to send HTTP response and close connection. We see code here

... takes no arguments and has a void return type?

If you are writing for System.Windows.Forms, You can also use:

public delegate void MethodInvoker()

You can code like two input box inside one div

<div class="input-group">
            <span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
            <input style="width:50% " class="form-control " placeholder="first name"  name="firstname" type="text" />
            <input style="width:50% " class="form-control " placeholder="lastname"  name="lastname" type="text" />
        </div>

Requests doesn't have an equivalent to Urlib2's read().

>>> import requests
>>> response = requests.get("http://www.google.com")
>>> print response.content
'<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage"><head>....'
>>> print response.content == response.text
True

It looks like the POST request you are making is returning no content. Which is often the case with a POST request. Perhaps it set a cookie? The status code is telling you that the POST succeeded after all.

Edit for Python 3:

Python now handles data types differently. response.content returns a sequence of bytes (integers that represent ASCII) while response.text is a string (sequence of chars).

Thus,

>>> print response.content == response.text
False

>>> print str(response.content) == response.text
True

A very good solution to this can be found here:

Here's a class that serves as a wrapper to a pyserial object. It allows you to read lines without 100% CPU. It does not contain any timeout logic. If a timeout occurs, self.s.read(i) returns an empty string and you might want to throw an exception to indicate the timeout.

It is also supposed to be fast according to the author:

The code below gives me 790 kB/sec while replacing the code with pyserial's readline method gives me just 170kB/sec.

class ReadLine:
    def __init__(self, s):
        self.buf = bytearray()
        self.s = s

    def readline(self):
        i = self.buf.find(b"\n")
        if i >= 0:
            r = self.buf[:i+1]
            self.buf = self.buf[i+1:]
            return r
        while True:
            i = max(1, min(2048, self.s.in_waiting))
            data = self.s.read(i)
            i = data.find(b"\n")

            else:
                self.buf.extend(data)

ser = serial.Serial('COM7', 9600)
rl = ReadLine(ser)

while True:

    print(rl.readline())

After instaling the package you need to add the newtonsoft.json.dll into assemble path by runing the flowing command.

Before we can use our assembly, we have to add it to the global assembly cache (GAC). Open the Visual Studio 2008 Command Prompt again (for Vista/Windows7/etc. open it as Administrator). And execute the following command. gacutil /i d:\myMethodsForSSIS\myMethodsForSSIS\bin\Release\myMethodsForSSIS.dll

I use this, and it works with all browsers:

<html>
    <head>
        <title>Stretched Background Image</title>
        <style type="text/css">
            /* Remove margins from the 'html' and 'body' tags, and ensure the page takes up full screen height. */
            html, body {height:100%; margin:0; padding:0;}

            /* Set the position and dimensions of the background image. */
            #page-background {position:fixed; top:0; left:0; width:100%; height:100%;}

            /* Specify the position and layering for the content that needs to appear in front of the background image. Must have a higher z-index value than the background image. Also add some padding to compensate for removing the margin from the 'html' and 'body' tags. */
            #content {position:relative; z-index:1; padding:10px;}
        </style>

You don't need to run any docker commands as sudo when you're using boot2docker as every command passed into the boot2docker VM runs as root by default.

You're seeing the error when you're running as sudo because sudo doesn't have the DOCKER_HOST env set, only your user does.

You can confirm this by doing a:

$ env

Then a

$ sudo env

And looking for DOCKER_HOST in each output.

As for having a docker file that runs your script, something like this might work for you:

Dockerfile

FROM busybox

# Copy your script into the docker image
ADD /path/to/your/script.sh /usr/local/bin/script.sh

# Run your script
CMD /usr/local/bin/script.sh

Then you can run:

docker build -t your-image-name:your-tag .

This will build your docker image, which you can see by doing a:

docker images

Then, to run your container, you can do a:

docker run your-image-name:your-tag

This run command will start a container from the image you created with your Dockerfile and your build command and then it will finish once your script.sh has finished executing.

Looking at the "effective POM" will probably help too. For instance, if you wanted to know what the path is for ${project.build.sourceDirectory}

you would find the related XML in the effective POM, such as: <project> <build> <sourceDirectory>/my/path</sourceDirectory>

Also helpful - you can do a real time evaluation of properties via the command line execution of mvn help:evaluate while in the same dir as the POM.

I did it like this in Python 3.4:

'''To write to screen in real-time'''
message = lambda x: print(x, flush=True, end="")
message('I am flushing out now...')

In addition to the popular answer above I would like to add a few notes for Windows-systems. The command

git filter-branch --tree-filter 'rm -rf node_modules' --prune-empty HEAD

• works perfectly without any modification! Therefore, you must not use Remove-Item, del or anything else instead of rm -rf.

• If you need to specify a path to a file or directory use slashes like ./path/to/node_modules

You might need to convert the decimal to money (or decimal(8,2)) to get that exact formatting. The convert method can take a third parameter that controls the formatting style:

convert(varchar, cast(price as money))       12345.67
convert(varchar, cast(price as money), 0)    12345.67
convert(varchar, cast(price as money), 1)    12,345.67

I think that is a frequently asked question about the behavior of figures in beamer slides produced from Pandoc and markdown. The real problem is, R Markdown produces PNG images by default (from knitr), and it is hard to get the size of PNG images correct in LaTeX by default (I do not know why). It is fairly easy, however, to get the size of PDF images correct. One solution is to reset the default graphical device to PDF in your first chunk:

```{r setup, include=FALSE}
knitr::opts_chunk$set(dev = 'pdf')
```

Then all the images will be written as PDF files, and LaTeX will be happy.

Your second problem is you are mixing up the HTML units with LaTeX units in out.width / out.height. LaTeX and HTML are very different technologies. You should not expect \maxwidth to work in HTML, or 200px in LaTeX. Especially when you want to convert Markdown to LaTeX, you'd better not set out.width / out.height (use fig.width / fig.height and let LaTeX use the original size).

The preferred way to specify toolchain-specific options is using CMake's toolchain facility. This ensures that there is a clean division between:

• instructions on how to organise source files into targets -- expressed in CMakeLists.txt files, entirely toolchain-agnostic; and
• details of how certain toolchains should be configured -- separated into CMake script files, extensible by future users of your project, scalable.

Ideally, there should be no compiler/linker flags in your CMakeLists.txt files -- even within if/endif blocks. And your program should build for the native platform with the default toolchain (e.g. GCC on GNU/Linux or MSVC on Windows) without any additional flags.

Steps to add a toolchain:

1. Create a file, e.g. arm-linux-androideadi-gcc.cmake with global toolchain settings:

   set(CMAKE_CXX_COMPILER arm-linux-gnueabihf-g++)
   set(CMAKE_CXX_FLAGS_INIT "-fexceptions")
   

   (You can find an example Linux cross-compiling toolchain file here.)

2. When you want to generate a build system with this toolchain, specify the CMAKE_TOOLCHAIN_FILE parameter on the command line:

   mkdir android-arm-build && cd android-arm-build
   cmake -DCMAKE_TOOLCHAIN_FILE=$(pwd)/../arm-linux-androideadi-gcc.cmake ..
   

   (Note: you cannot use a relative path.)

3. Build as normal:

   cmake --build .
   

Toolchain files make cross-compilation easier, but they have other uses:

• Hardened diagnostics for your unit tests.

  set(CMAKE_CXX_FLAGS_INIT "-Werror -Wall -Wextra -Wpedantic")
  

• Tricky-to-configure development tools.

  # toolchain file for use with gcov
  set(CMAKE_CXX_FLAGS_INIT "--coverage -fno-exceptions -g")
  

• Enhanced safety checks.

  # toolchain file for use with gdb
  set(CMAKE_CXX_FLAGS_DEBUG_INIT "-fsanitize=address,undefined -fsanitize-undefined-trap-on-error")
  set(CMAKE_EXE_LINKER_FLAGS_INIT "-fsanitize=address,undefined -static-libasan")
  

Two things:

1. Only need one (1) equals sign to evaluate
2. You need to specify a length on the VARCHAR - the default is a single character.

Use:

DECLARE @temp VARCHAR(10)
    SET @temp = 'm'

IF @temp = 'm'
  SELECT 'yes'
ELSE
  SELECT 'no'

VARCHAR(10) means the VARCHAR will accommodate up to 10 characters. More examples of the behavior -

DECLARE @temp VARCHAR
    SET @temp = 'm'

IF @temp = 'm'
  SELECT 'yes'
ELSE
  SELECT 'no'

...will return "yes"

DECLARE @temp VARCHAR
    SET @temp = 'mtest'

IF @temp = 'm'
  SELECT 'yes'
ELSE
  SELECT 'no'

...will return "no".

For a more flexible and faster approach to data aggregation, check out the collap function in the collapse R package available on CRAN:

library(collapse)
# Simple aggregation with one function
head(collap(df1, x1 + x2 ~ year + month, fmean))

  year month        x1        x2
1 2000     1 -1.217984  4.008534

6 2000     6 -1.415203 48.252283

# Customized: Aggregate columns with different functions
head(collap(df1, x1 + x2 ~ year + month, 
      custom = list(fmean = c("x1", "x2"), fmedian = "x2")))

  year month  fmean.x1  fmean.x2 fmedian.x2

6 2000     6 -1.415203 48.252283  48.653926

# You can also apply multiple functions to all columns
head(collap(df1, x1 + x2 ~ year + month, list(fmean, fmin, fmax)))

  year month  fmean.x1    fmin.x1  fmax.x1  fmean.x2   fmin.x2  fmax.x2

# When you do that, you can also return the data in a long format
head(collap(df1, x1 + x2 ~ year + month, list(fmean, fmin, fmax), return = "long"))

  Function year month        x1        x2

6    fmean 2000     6 -1.415203 48.252283

Note: You can use base functions like mean, max etc. with collap, but fmean, fmax etc. are C++ based grouped functions offered in the collapse package which are significantly faster (i.e. the performance on large data aggregations is the same as data.table while providing greater flexibility, and these fast grouped functions can also be used without collap).

Note2: collap also supports flexible multitype data aggregation, which you can of course do using the custom argument, but you can also apply functions to numeric and non-numeric columns in a semi-automated way:

# wlddev is a data set of World Bank Indicators provided in the collapse package
head(wlddev)

You are missing JUnit 5 platform launcher with group: 'org.junit.platform', name: 'junit-platform-launcher'

Just add in ur POM:

<dependency>
       <groupId>org.junit.platform</groupId>
       <artifactId>junit-platform-launcher</artifactId>
    </dependency>

Make sure you have a jdk setup. To do this, create a new project and then go to file -> project structure. From there you can add a new jdk. Once that is setup, go back to your gradle project and you should have a jdk to select in the 'Gradle JVM' field.

The error you mean is due to missing additional include path. Try adding it with: INCLUDEPATH += C:\path\to\include\files\ Hope it works. Regards.

I solved this problem by changing the data type. If you see the 'Energy Supply per Capita' is a numerical type while the 'Citable docs per Capita' is an object type. I converted the column to float using astype. I had the same problem with some np functions: count_nonzero and sum worked while mean and std didn't.

This is the most efficient way to see if a number is prime, if you only have a few query. If you ask a lot of numbers if they are prime try Sieve of Eratosthenes.

import math

def is_prime(n):
    if n == 2:
        return True
    if n % 2 == 0 or n <= 1:
        return False

    sqr = int(math.sqrt(n)) + 1

    for divisor in range(3, sqr, 2):
        if n % divisor == 0:
            return False
    return True

1. Select your project in the navigator on left.
2. Open up the drawer in the middle pane and select your target.
3. Select Build Phases
4. Target Dependencies is an option at that point.

To make the transform work in development (using F5 or CTRL + F5) I drop ctt.exe (https://ctt.codeplex.com/) in the packages folder (packages\ConfigTransform\ctt.exe).

Then I register a pre- or post-build event in Visual Studio...

$(SolutionDir)packages\ConfigTransform\ctt.exe source:"$(ProjectDir)connectionStrings.config" transform:"$(ProjectDir)connectionStrings.$(ConfigurationName).config" destination:"$(ProjectDir)connectionStrings.config"
$(SolutionDir)packages\ConfigTransform\ctt.exe source:"$(ProjectDir)web.config" transform:"$(ProjectDir)web.$(ConfigurationName).config" destination:"$(ProjectDir)web.config"

For the transforms I use SlowCheeta VS extension (https://visualstudiogallery.msdn.microsoft.com/69023d00-a4f9-4a34-a6cd-7e854ba318b5).

Add position: relative to .outside. (https://developer.mozilla.org/en-US/docs/CSS/position)

Elements that are positioned relatively are still considered to be in the normal flow of elements in the document. In contrast, an element that is positioned absolutely is taken out of the flow and thus takes up no space when placing other elements. The absolutely positioned element is positioned relative to nearest positioned ancestor. If a positioned ancestor doesn't exist, the initial container is used.

The "initial container" would be <body>, but adding the above makes .outside positioned.

To add yet another potential solution, Helium by Clockworkmod has it's own version of ADB built in that kept being started. Exiting the Helium Desktop application resolves the issue.

It's better to create a new factor variable using cut(). I've added a few options using ggplot2 also.

df <- data.frame(
  X1=seq(0, 5, by=0.001),
  X2=rnorm(df$X1, mean = 3.5, sd = 1.5)
)

# Create new variable for plotting
df$Colour <- cut(df$X2, breaks = c(-Inf, 1, 3, +Inf), 
                 labels = c("low", "medium", "high"), 
                 right = FALSE)

### Base Graphics

plot(df$X1, df$X2, 
     col = df$Colour, ylim = c(0, 10), xlab = "POS", 
     ylab = "CS", main = "Plot Title", pch = 21)

plot(df$X1,df$X2, 
     col = df$Colour, ylim = c(0, 10), xlab = "POS", 
     ylab = "CS", main = "Plot Title", pch = 19, cex = 0.5)

# Using `with()` 

with(df, 
     plot(X1, X2, xlab="POS", ylab="CS", col = Colour, pch=21, cex=1.4)
     )

# Using ggplot2
library(ggplot2)

# qplot()
qplot(df$X1, df$X2, colour = df$Colour)

# ggplot()
p <- ggplot(df, aes(X1, X2, colour = Colour)) 
p <- p + geom_point() + xlab("POS") + ylab("CS")
p

p + facet_grid(Colour~., scales = "free")

Tips from 2020:

From Flask 1.0, it defaults to enable multiple threads (source), you don't need to do anything, just upgrade it with:

$ pip install -U flask

If you are using flask run instead of app.run() with older versions, you can control the threaded behavior with a command option (--with-threads/--without-threads):

$ flask run --with-threads

It's same as app.run(threaded=True)

The Extended WPF Toolkit has one: NumericUpDown

You can add:

#div2{
    background-image:url(http://s7.static.hootsuite.com/3-0-48/images/themes/classic/streams/message-gradient.png);
    background-size: 100% 100%;
    height:180px;
    width:200px;
    border: 1px solid red;
}

You can read more about it here: css3 background-size

You cannot refer non-static members from a static method.

Non-Static members (like your fxn(int y)) can be called only from an instance of your class.

Example:

You can do this:

       public class A
       {
           public   int fxn(int y) {
              y = 5;
              return y;
          }
       }


  class Two {
public static void main(String[] args) {
    int x = 0;
    A a = new A();
    System.out.println("x = " + x);
    x = a.fxn(x);
    System.out.println("x = " + x);
}

or you can declare you method as static.

Might be useful. I needed the action in the constructor of the controller, and it appears at this point of the MVC lifecycle, this hasn't initialized, and ControllerContext = null. Instead of delving into the MVC lifecycle and finding the appropriate function name to override, I just found the action in the RequestContext.RouteData.

But in order to do so, as with any HttpContext related uses in the constructor, you have to specify the full namespace, because this.HttpContext also hasn't been initialized. Luckily, it appears System.Web.HttpContext.Current is static.

// controller constructor
public MyController() {
    // grab action from RequestContext
    string action = System.Web.HttpContext.Current.Request.RequestContext.RouteData.GetRequiredString("action");

    // grab session (another example of using System.Web.HttpContext static reference)
    string sessionTest = System.Web.HttpContext.Current.Session["test"] as string
}

NOTE: likely not the most supported way to access all properties in HttpContext, but for RequestContext and Session it appears to work fine in my application.

I think not only is the question not clear but most people also are not cognizant of the difference. Examine the following saying,

POSIX thread IDs are not the same as the thread IDs returned by the Linux specific gettid() system call. POSIX thread IDs are assigned and maintained by the threading implementation. The thread ID returned by gettid() is a number (similar to a process ID) that is assigned by the kernel. Although each POSIX thread has a unique kernel thread ID in the Linux NPTL threading implementation, an application generally doesn’t need to know about the kernel IDs (and won’t be portable if it depends on knowing them).

Excerpted from: The Linux Programming Interface: A Linux and UNIX System Programming Handbook, Michael Kerrisk

IMHO, there is only one portable way that pass a structure in which define a variable holding numbers in an ascending manner e.g. 1,2,3... to per thread. By doing this, threads' id can be kept track. Nonetheless, int pthread_equal(tid1, tid2) function should be used.

if (pthread_equal(tid1, tid2)) printf("Thread 2 is same as thread 1.\n");
else printf("Thread 2 is NOT same as thread 1.\n");

This is not politically correct but works

If you want a dynamically sized array, then you should make a list. Not only will you get the .Add() functionality, but as @frode-f explains, dynamic arrays are more memory efficient and a better practice anyway.

And it's so easy to use.

Instead of your array declaration, try this:

$outItems = New-Object System.Collections.Generic.List[System.Object]

Adding items is simple.

$outItems.Add(1)
$outItems.Add("hi")

And if you really want an array when you're done, there's a function for that too.

$outItems.ToArray()

I know this is old post but JsonConvert actually has a different method so it would be

var product = new { Name = "", Price = 0 };
var jsonResponse = JsonConvert.DeserializeAnonymousType(json, product);

Line ending format used in OS

• Windows: CR (Carriage Return \r) and LF (LineFeed \n) pair
• OSX,Linux: LF (LineFeed \n)

We can configure git to auto-correct line ending formats for each OS in two ways.

1. Git Global configuration
2. Use .gitattributes file

Global Configuration

git config --global core.autocrlf input

This will fix any CRLF to LF when you commit.

git config --global core.autocrlf true

This will make sure when you checkout in windows, all LF will convert to CRLF

.gitattributes File

It is a good idea to keep a .gitattributes file as we don't want to expect everyone in our team set their config. This file should keep in repo's root path and if exist one, git will respect it.

* text=auto

This will treat all files as text files and convert to OS's line ending on checkout and back to LF on commit automatically. If wanted to tell explicitly, then use

* text eol=crlf
* text eol=lf

First one is for checkout and second one is for commit.

*.jpg binary

Treat all .jpg images as binary files, regardless of path. So no conversion needed.

Or you can add path qualifiers:

my_path/**/*.jpg binary

VanDyke VShell is the best Windows SSH Server I've ever worked with. It is kind of expensive though ($250). If you want a free solution, freeSSHd works okay. The CYGWIN solution is always an option, I've found, however, that it is a lot of work & overhead just to get SSH.

It's perhaps because you copied code from net ( from a site which has perhaps not an ASCII encoded page, but UTF-8 encoded page), so you can convert the code to ASCII from this site :

"http://www.percederberg.net/tools/text_converter.html"

There you can either detect errors manually by converting it back to UTF-8, or you can automatically convert it to ASCII and remove all the stray characters.

SQL Server CONVERT() Function

benchmark for Michael Currie's answer

import perfplot

bench_x = perfplot.bench(
    n_range= range(1, 200),
    setup  = lambda n: (n, n),
    kernels= [
        lambda shape: np.ones(shape, dtype= bool),
        lambda shape: np.full(shape, True)
    ],
    labels = ['ones', 'full']
)

bench_x.show()

I don't know what you mean by 'manually'. You can choose a colourmap and make a colour array easily enough:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cm as cm

x = np.arange(10)
ys = [i+x+(i*x)**2 for i in range(10)]

colors = cm.rainbow(np.linspace(0, 1, len(ys)))
for y, c in zip(ys, colors):
    plt.scatter(x, y, color=c)

Or you can make your own colour cycler using itertools.cycle and specifying the colours you want to loop over, using next to get the one you want. For example, with 3 colours:

import itertools

colors = itertools.cycle(["r", "b", "g"])
for y in ys:
    plt.scatter(x, y, color=next(colors))

Come to think of it, maybe it's cleaner not to use zip with the first one neither:

colors = iter(cm.rainbow(np.linspace(0, 1, len(ys))))
for y in ys:
    plt.scatter(x, y, color=next(colors))

This is for create a text file

For i = 1 to 10
    createFile( i )
Next

Public Sub createFile(a)

    Dim fso,MyFile
    filePath = "C:\file_name" & a & ".txt"
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set MyFile = fso.CreateTextFile(filePath)
    MyFile.WriteLine("This is a separate file")
    MyFile.close

End Sub

And this for read a text file

Dim fso
Set fso = CreateObject("Scripting.FileSystemObject")
Set dict = CreateObject("Scripting.Dictionary")
Set file = fso.OpenTextFile ("test.txt", 1)
row = 0
Do Until file.AtEndOfStream
  line = file.Readline
  dict.Add row, line
  row = row + 1
Loop

file.Close

For Each line in dict.Items
  WScript.Echo line
  WScript.Sleep 1000
Next

Er - that would imply that you are invoking your function with arguments which aren't in the proper order... which I would not recommend.

I would recommend instead feeding an object to your function like so:

function getData( props ) {
    props = props || {};
    props.params = props.params || {};
    props.id = props.id || 1;
    props.callback = props.callback || function(){};
    alert( props.callback )
};

getData( {
    id: 3,
    callback: function(){ alert('hi'); }
} );

Benefits:

• you don't have to account for argument order
• you don't have to do type checking
• it's easier to define default values because no type checking is necessary
• less headaches. imagine if you added a fourth argument, you'd have to update your type checking every single time, and what if the fourth or consecutive are also functions?

Drawbacks:

• time to refactor code

If you have no choice, you could use a function to detect whether an object is indeed a function ( see last example ).

Note: This is the proper way to detect a function:

function isFunction(obj) {
    return Object.prototype.toString.call(obj) === "[object Function]";
}

isFunction( function(){} )

Markit On Demand provides a set of free financial APIs for playing around with. Looks like there is a stock quote API, a stock ticker/company search and a charting API available. Look at http://dev.markitondemand.com

The simple difference between document ready and page event in jQuery-mobile is that:

1. The document ready event is used for the whole HTML page,

   $(document).ready(function(e) {
       // Your code
   });
   

2. When there is a page event, use for handling particular page event:

   <div data-role="page" id="second">
       <div data-role="header">
           <h3>
               Page header
           </h3>
       </div>
       <div data-role="content">
           Page content
       </div> <!--content-->
       <div data-role="footer">
           Page footer
       </div> <!--footer-->
   </div><!--page-->
   

You can also use document for handling the pageinit event:

$(document).on('pageinit', "#mypage", function() {

});

For people that have PowerShell 3 or later (i.e. Windows Server 2012+ or Windows Server 2008 R2 with the Windows Management Framework 4.0 update), you can do this one-liner instead of invoking System.Net.WebRequest:

[enhanced version]
This is going to be much faster and precise than the initial version below and will output the sum of all the file size of current directory:

echo `find . -type f -exec stat -c %s {} \; | tr '\n' '+' | sed 's/+$//g'` | bc

the stat -c %s command on a file will return its size in bytes. The tr command here is used to overcome xargs command limitations (apparently piping to xargs is splitting results on more lines, breaking the logic of my command). Hence tr is taking care of replacing line feed with + (plus) sign. sed has the only goal to remove the last + sign from the resulting string to avoid complains from the final bc (basic calculator) command that, as usual, does the math.

Performances: I tested it on several directories and over ~150.000 files top (the current number of files of my fedora 15 box) having what I believe it is an amazing result:

# time echo `find / -type f -exec stat -c %s {} \; | tr '\n' '+' | sed 's/+$//g'` | bc
12671767700

real    2m19.164s
user    0m2.039s
sys 0m14.850s

Just in case you want to make a comparison with the du -sb / command, it will output an estimated disk usage in bytes (-b option)

# du -sb /
12684646920 /

As I was expecting it is a little larger than my command calculation because the du utility returns allocated space of each file and not the actual consumed space.

[initial version]
You cannot use du command if you need to know the exact sum size of your folder because (as per man page citation) du estimates file space usage. Hence it will lead you to a wrong result, an approximation (maybe close to the sum size but most likely greater than the actual size you are looking for).

I think there might be different ways to answer your question but this is mine:

ls -l $(find . -type f | xargs) | cut -d" " -f5 | xargs | sed 's/\ /+/g'| bc

It finds all files under . directory (change . with whatever directory you like), also hidden files are included and (using xargs) outputs their names in a single line, then produces a detailed list using ls -l. This (sometimes) huge output is piped towards cut command and only the fifth field (-f5), which is the file size in bytes is taken and again piped against xargs which produces again a single line of sizes separated by blanks. Now take place a sed magic which replaces each blank space with a plus (+) sign and finally bc (basic calculator) does the math.

It might need additional tuning and you may have ls command complaining about arguments list too long.

If SDK folder is present in system, one can find in C:\Users\%USERNAME%\AppData\Local\Android

If Android/SDK folder is not found Once done with downloading and installing Android Studio, you need to launch studio. On launching Android studio for the first time, we get option to download further more components, in that we have SDK. On downloading components one can find SDK under Appdata (C:\Users\%USERNAME%\AppData\Local\Android)

It may be a bit offtopic, but anyway. You can program c++ right on iOS devices. Check out CppCode ios app - http://cppcode.info. I believe it helps to learn c and c++ and objective-c later.

You can use:

set content=
for /f "delims=" %%i in ('type text.txt') do set content=!content! %%i

It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.

Are you doing heavy DOM manipulation? I would use jQuery and Backbone.

Very data driven app? Angular with its nice data binding.

Game programming? None - direct to canvas; maybe a game engine.

My Comments:

When I see the output, the output is mixed with One, Two, Three which are the thread names and they run simultaneously. I am not sure when you say thread is not running by main method.

Not sure if I understood your question or not. But I m putting my answer what I could understand, hope it can help you.

1) Then you created the object, it called the constructor, in construct it has start method which started the thread and executed the contents written inside run() method.

So as you created 3 objects (3 threads - one, two, three), all 3 threads started executing simultaneously.

2) Join and Synchronization They are 2 different things, Synchronization is when there are multiple threads sharing a common resource and one thread should use that resource at a time. E.g. Threads such as DepositThread, WithdrawThread etc. do share a common object as BankObject. So while DepositThread is running, the WithdrawThread will wait if they are synchronized. wait(), notify(), notifyAll() are used for inter-thread communication. Plz google to know more.

about Join(), it is when multiple threads are running, but you join. e.g. if there are two thread t1 and t2 and in multi-thread env they run, the output would be: t1-0 t2-0 t1-1 t2-1 t1-2 t2-2

and we use t1.join(), it would be: t1-0 t1-1 t1-2 t2-0 t2-1 t2-2

This is used in realtime when sometimes you don't mix up the thread in certain conditions and one depends another to be completed (not in shared resource), so you can call the join() method.

Something different:

wc -l `tree -if --noreport | grep -e'\.php$'`

This works out fine, but you need to have at least one *.php file in the current folder or one of its subfolders, or else wc stalls.

If your question is how can I determine how many clusters are appropriate for a kmeans analysis of my data?, then here are some options. The wikipedia article on determining numbers of clusters has a good review of some of these methods.

First, some reproducible data (the data in the Q are... unclear to me):

n = 100
g = 6 
set.seed(g)
d <- data.frame(x = unlist(lapply(1:g, function(i) rnorm(n/g, runif(1)*i^2))), 
                y = unlist(lapply(1:g, function(i) rnorm(n/g, runif(1)*i^2))))
plot(d)

One. Look for a bend or elbow in the sum of squared error (SSE) scree plot. See http://www.statmethods.net/advstats/cluster.html & http://www.mattpeeples.net/kmeans.html for more. The location of the elbow in the resulting plot suggests a suitable number of clusters for the kmeans:

mydata <- d
wss <- (nrow(mydata)-1)*sum(apply(mydata,2,var))
  for (i in 2:15) wss[i] <- sum(kmeans(mydata,
                                       centers=i)$withinss)
plot(1:15, wss, type="b", xlab="Number of Clusters",
     ylab="Within groups sum of squares")

We might conclude that 4 clusters would be indicated by this method:

Two. You can do partitioning around medoids to estimate the number of clusters using the pamk function in the fpc package.

library(fpc)
pamk.best <- pamk(d)
cat("number of clusters estimated by optimum average silhouette width:", pamk.best$nc, "\n")
plot(pam(d, pamk.best$nc))

# we could also do:
library(fpc)
asw <- numeric(20)
for (k in 2:20)
  asw[[k]] <- pam(d, k) $ silinfo $ avg.width
k.best <- which.max(asw)
cat("silhouette-optimal number of clusters:", k.best, "\n")
# still 4

Three. Calinsky criterion: Another approach to diagnosing how many clusters suit the data. In this case we try 1 to 10 groups.

require(vegan)
fit <- cascadeKM(scale(d, center = TRUE,  scale = TRUE), 1, 10, iter = 1000)
plot(fit, sortg = TRUE, grpmts.plot = TRUE)
calinski.best <- as.numeric(which.max(fit$results[2,]))
cat("Calinski criterion optimal number of clusters:", calinski.best, "\n")
# 5 clusters!

Four. Determine the optimal model and number of clusters according to the Bayesian Information Criterion for expectation-maximization, initialized by hierarchical clustering for parameterized Gaussian mixture models

# See http://www.jstatsoft.org/v18/i06/paper
# http://www.stat.washington.edu/research/reports/2006/tr504.pdf
#
library(mclust)
# Run the function to see how many clusters
# it finds to be optimal, set it to search for
# at least 1 model and up 20.
d_clust <- Mclust(as.matrix(d), G=1:20)
m.best <- dim(d_clust$z)[2]
cat("model-based optimal number of clusters:", m.best, "\n")
# 4 clusters
plot(d_clust)

Five. Affinity propagation (AP) clustering, see http://dx.doi.org/10.1126/science.1136800

library(apcluster)
d.apclus <- apcluster(negDistMat(r=2), d)
cat("affinity propogation optimal number of clusters:", length(d.apclus@clusters), "\n")
# 4
heatmap(d.apclus)
plot(d.apclus, d)

Six. Gap Statistic for Estimating the Number of Clusters. See also some code for a nice graphical output. Trying 2-10 clusters here:

library(cluster)
clusGap(d, kmeans, 10, B = 100, verbose = interactive())

Clustering k = 1,2,..., K.max (= 10): .. done
Bootstrapping, b = 1,2,..., B (= 100)  [one "." per sample]:
.................................................. 50 
.................................................. 100 
Clustering Gap statistic ["clusGap"].
B=100 simulated reference sets, k = 1..10
 --> Number of clusters (method 'firstSEmax', SE.factor=1): 4
          logW   E.logW        gap     SE.sim
 [1,] 5.991701 5.970454 -0.0212471 0.04388506

 [4,] 3.928959 4.880453  0.9514943 0.04630399
 [5,] 3.789319 4.766903  0.9775842 0.04826191
 [6,] 3.747539 4.670100  0.9225607 0.03898850
 [7,] 3.582373 4.590136  1.0077628 0.04892236

[10,] 3.445291 4.369232  0.9239414 0.05055486

Here's the output from Edwin Chen's implementation of the gap statistic:

Seven. You may also find it useful to explore your data with clustergrams to visualize cluster assignment, see http://www.r-statistics.com/2010/06/clustergram-visualization-and-diagnostics-for-cluster-analysis-r-code/ for more details.

Eight. The NbClust package provides 30 indices to determine the number of clusters in a dataset.

library(NbClust)
nb <- NbClust(d, diss=NULL, distance = "euclidean",
        method = "kmeans", min.nc=2, max.nc=15, 
        index = "alllong", alphaBeale = 0.1)
hist(nb$Best.nc[1,], breaks = max(na.omit(nb$Best.nc[1,])))
# Looks like 3 is the most frequently determined number of clusters
# and curiously, four clusters is not in the output at all!

If your question is how can I produce a dendrogram to visualize the results of my cluster analysis, then you should start with these: http://www.statmethods.net/advstats/cluster.html http://www.r-tutor.com/gpu-computing/clustering/hierarchical-cluster-analysis http://gastonsanchez.wordpress.com/2012/10/03/7-ways-to-plot-dendrograms-in-r/ And see here for more exotic methods: http://cran.r-project.org/web/views/Cluster.html

Here are a few examples:

d_dist <- dist(as.matrix(d))   # find distance matrix 
plot(hclust(d_dist))           # apply hirarchical clustering and plot

# a Bayesian clustering method, good for high-dimension data, more details:
# http://vahid.probstat.ca/paper/2012-bclust.pdf
install.packages("bclust")
library(bclust)
x <- as.matrix(d)
d.bclus <- bclust(x, transformed.par = c(0, -50, log(16), 0, 0, 0))
viplot(imp(d.bclus)$var); plot(d.bclus); ditplot(d.bclus)
dptplot(d.bclus, scale = 20, horizbar.plot = TRUE,varimp = imp(d.bclus)$var, horizbar.distance = 0, dendrogram.lwd = 2)
# I just include the dendrogram here

Also for high-dimension data is the pvclust library which calculates p-values for hierarchical clustering via multiscale bootstrap resampling. Here's the example from the documentation (wont work on such low dimensional data as in my example):

library(pvclust)
library(MASS)
data(Boston)
boston.pv <- pvclust(Boston)
plot(boston.pv)

Does any of that help?

Another option is to use find and then pass it through sed.

find /path/to/files -type f -exec sed -i 's/oldstring/new string/g' {} \;

The problem

I literally quote Saeed Neamati (https://stackoverflow.com/a/6587434/760777):

In your request header, you have sent Content-Type: text/html which means that you'd like to interpret the response as HTML. Now if even server send you PDF files, your browser tries to understand it as HTML.

The solution

Send the bloody correct header. Send the correct mime type of the file. Period!

How?

Aaah. That totally depends on what you are doing (OS, language).

My problem was with a dynamically created download link in javascript. The link is for downloading an mp3 file. An mp3 file is not a document, neither is a pdf, a zip file, a flac file and the list goes on.

So I created the link like this:

<form method="get" action="test.mp3"> 
  <a href="#" onclick="this.closest(form).submit();return false;" target="_blank">
    <span class="material-icons">
      download
    </span>
  </a>
</form>

and I changed it to this:

<form method="get" action="test.mp3" enctype="multipart/form-data"> 
  <a href="#" onclick="this.closest(form).submit();return false;" target="_blank">
    <span class="material-icons">
      download
    </span>
  </a>
</form>

Problem solved. Adding an extra attribute to the form tag solved it. But there is no generic solution. There are many different scenario's. When you send a file from the server (you created it dynamically with a language like CX#, Java, PHP), you have to send the correct header(s) with it.

Side note: And be careful not to send anything (text!) before you send your header(s).

This is an improvement over the accepted answer.

Changes:

(1) Using random IV and prepend it to the encrypted text

(2) Using SHA-256 to generate a key from a passphrase

(3) No dependency on Apache Commons

public static void main(String[] args) throws GeneralSecurityException {
    String plaintext = "Hello world";
    String passphrase = "My passphrase";
    String encrypted = encrypt(passphrase, plaintext);
    String decrypted = decrypt(passphrase, encrypted);
    System.out.println(encrypted);
    System.out.println(decrypted);
}

private static SecretKeySpec getKeySpec(String passphrase) throws NoSuchAlgorithmException {
    MessageDigest digest = MessageDigest.getInstance("SHA-256");
    return new SecretKeySpec(digest.digest(passphrase.getBytes(UTF_8)), "AES");
}

private static Cipher getCipher() throws NoSuchPaddingException, NoSuchAlgorithmException {
    return Cipher.getInstance("AES/CBC/PKCS5PADDING");
}

public static String encrypt(String passphrase, String value) throws GeneralSecurityException {
    byte[] initVector = new byte[16];
    SecureRandom.getInstanceStrong().nextBytes(initVector);
    Cipher cipher = getCipher();
    cipher.init(Cipher.ENCRYPT_MODE, getKeySpec(passphrase), new IvParameterSpec(initVector));
    byte[] encrypted = cipher.doFinal(value.getBytes());
    return DatatypeConverter.printBase64Binary(initVector) +
            DatatypeConverter.printBase64Binary(encrypted);
}

public static String decrypt(String passphrase, String encrypted) throws GeneralSecurityException {
    byte[] initVector = DatatypeConverter.parseBase64Binary(encrypted.substring(0, 24));
    Cipher cipher = getCipher();
    cipher.init(Cipher.DECRYPT_MODE, getKeySpec(passphrase), new IvParameterSpec(initVector));
    byte[] original = cipher.doFinal(DatatypeConverter.parseBase64Binary(encrypted.substring(24)));
    return new String(original);
}

No, there are no dictionaries in php. The closest thing you have is an array. However, an array is different than a dictionary in that arrays have both an index and a key. Dictionaries only have keys and no index. What do I mean by that?

$array = array(
    "foo" => "bar",
    "bar" => "foo"
);

// as of PHP 5.4
$array = [
    "foo" => "bar",
    "bar" => "foo",
];

The following line is allowed with the above array but would give an error if it was a dictionary.

print $array[0]

Python has both arrays and dictionaries.

it's nilin Ruby, not null. And it's enough to say if @objectname to test whether it's not nil. And no then. You can find more on if syntax here:

http://en.wikibooks.org/wiki/Ruby_Programming/Syntax/Control_Structures#if

The answers above check if a filesystem contains a path that is a file or directory. But it doesn't identify if a given path alone is a file or directory.

The answer is to identify directory-based paths using "/." like --> "/c/dos/run/." <-- trailing period.

Like a path of a directory or file that has not been written yet. Or a path from a different computer. Or a path where both a file and directory of the same name exists.

// /tmp/
// |- dozen.path
// |- dozen.path/.
//    |- eggs.txt
//
// "/tmp/dozen.path" !== "/tmp/dozen.path/"
//
// Very few fs allow this. But still. Don't trust the filesystem alone!

// Converts the non-standard "path-ends-in-slash" to the standard "path-is-identified-by current "." or previous ".." directory symbol.
function tryGetPath(pathItem) {
    const isPosix = pathItem.includes("/");
    if ((isPosix && pathItem.endsWith("/")) ||
        (!isPosix && pathItem.endsWith("\\"))) {
        pathItem = pathItem + ".";
    }
    return pathItem;
}
// If a path ends with a current directory identifier, it is a path! /c/dos/run/. and c:\dos\run\.
function isDirectory(pathItem) {
    const isPosix = pathItem.includes("/");
    if (pathItem === "." || pathItem ==- "..") {
        pathItem = (isPosix ? "./" : ".\\") + pathItem;
    }
    return (isPosix ? pathItem.endsWith("/.") || pathItem.endsWith("/..") : pathItem.endsWith("\\.") || pathItem.endsWith("\\.."));
} 
// If a path is not a directory, and it isn't empty, it must be a file
function isFile(pathItem) {
    if (pathItem === "") {
        return false;
    }
    return !isDirectory(pathItem);
}

Last thought: Why even hit the filesystem?

I too had the same problem. Digging into this I found that the Exception class has an args attribute, which captures the arguments that were used to create the exception. If you narrow the exceptions that except will catch to a subset, you should be able to determine how they were constructed, and thus which argument contains the message.

try:
   # do something that may raise an AuthException
except AuthException as ex:
   if ex.args[0] == "Authentication Timeout.":
      # handle timeout
   else:
      # generic handling

Just in case any Windows users are having trouble, I thought I'd add my own experience. When running python manage.py runserver 0.0.0.0:8000, I could view urls using localhost:8000, but not my ip address 192.168.1.3:8000.

I ended up disabling ipv6 on my wireless adapter, and running ipconfig /renew. After this everything worked as expected.

Some things to try:

1. Restart the rails console; changes to your models will only get picked up by a rails console that is already open if you do > reload! (although I have found this to be unpredictable), or by restarting the console.

2. Is your model file called "phone_number.rb" and is it in "/app/models"?

3. You should double-check the "--sandbox" option on your rails console command. AFAIK, this prevents changes. Try it without the switch.

H?llo from 2020. Let me bring String.prototype.matchAll() to your attention:

let regexp = /(?:&|&)?([^=]+)=([^&]+)/g;
let str = '1111342=Adam%20Franco&348572=Bob%20Jones';

for (let match of str.matchAll(regexp)) {
    let [full, key, value] = match;
    console.log(key + ' => ' + value);
}

Outputs:

1111342 => Adam%20Franco
348572 => Bob%20Jones

Here is a variant of the first solution using reduce, in case you like being functional. :)

repls = {'hello' : 'goodbye', 'world' : 'earth'}
s = 'hello, world'
reduce(lambda a, kv: a.replace(*kv), repls.iteritems(), s)

martineau's even better version:

repls = ('hello', 'goodbye'), ('world', 'earth')
s = 'hello, world'
reduce(lambda a, kv: a.replace(*kv), repls, s)

As addition to the answers above:

If you would like to delete those files

find $dir -size 0 -type f -delete

Vector has some handy features:

Vector<String> siteIdVector = new Vector<>(siteIdSet);
String first = siteIdVector.firstElement();
String last = siteIdVector.lastElement();

But I do agree - this may have unintended consequences, since the underling set is not guaranteed to be ordered.

SilverSkin and Anders are both correct. You can use parentheses to execute multiple commands. However, you have to make sure that the commands themselves (and their parameters) do not contain parentheses. cmd greedily searches for the first closing parenthesis, instead of handling nested sets of parentheses gracefully. This may cause the rest of the command line to fail to parse, or it may cause some of the parentheses to get passed to the commands (e.g. DEL myfile.txt)).

A workaround for this is to split the body of the loop into a separate function. Note that you probably need to jump around the function body to avoid "falling through" into it.

FOR /r %%X IN (*.txt) DO CALL :loopbody %%X
REM Don't "fall through" to :loopbody.
GOTO :EOF

:loopbody
ECHO %1
DEL %1
GOTO :EOF

center-block is bad idea as it covers a portion on your screen and you cannot click on your fields or buttons. col-md-offset-? is better option.

Use col-md-offset-3 is better option if class is col-sm-6. Just change the number to center your block.

The correct command for installing the current version of OpenCV 3.3 in Anaconda windows:

conda install -c conda-forge opencv

or

conda install -c conda-forge/label/broken opencv

For 3.2 use this:

conda install -c menpo opencv3

React Native

• It is a framework for building native applications using JavaScript.

• It compiles to native app components, which makes it possible for you to build native mobile applications.

• No need to overhaul your old app. All you have to do is add React Native UI components into your existing app’s code, without having to rewrite.

React js

• It supporting both front-end web and being run on a server, for building user interfaces and web applications.

• It also allows us to create reusable UI components.

• You can reuse code components in React JS, saving you a lot of time.

https://github.com/kubernetes/helm/blob/master/docs/charts_tips_and_tricks.md#user-content-automatically-roll-deployments-when-configmaps-or-secrets-change

Often times configmaps or secrets are injected as configuration files in containers. Depending on the application a restart may be required should those be updated with a subsequent helm upgrade, but if the deployment spec itself didn't change the application keeps running with the old configuration resulting in an inconsistent deployment.

The sha256sum function can be used together with the include function to ensure a deployments template section is updated if another spec changes:

kind: Deployment
spec:
  template:
    metadata:
      annotations:
        checksum/config: {{ include (print $.Template.BasePath "/secret.yaml") . | sha256sum }}
[...]

In my case, for some reasons, $.Template.BasePath didn't work but $.Chart.Name does:

spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: admin-app
      annotations:
        checksum/config: {{ include (print $.Chart.Name "/templates/" $.Chart.Name "-configmap.yaml") . | sha256sum }}

this works for me,

$(function() { $('.datepicker').datepicker({ startDate: '-0m', autoclose: true }); });

You can use different types of redirect method in laravel -

return redirect()->intended('http://heera.it');

OR

return redirect()->to('http://heera.it');

OR

use Illuminate\Support\Facades\Redirect;

return Redirect::to('/')->with(['type' => 'error','message' => 'Your message'])->withInput(Input::except('password'));

OR

return redirect('/')->with(Auth::logout());

OR

return redirect()->route('user.profile', ['step' => $step, 'id' => $id]);

Here is an example on Python 3.x, much simpler than 2.x:

import smtplib
from email.message import EmailMessage
def send_mail(to_email, subject, message, server='smtp.example.cn',
              from_email='[email protected]'):
    # import smtplib
    msg = EmailMessage()
    msg['Subject'] = subject
    msg['From'] = from_email
    msg['To'] = ', '.join(to_email)
    msg.set_content(message)
    print(msg)
    server = smtplib.SMTP(server)
    server.set_debuglevel(1)
    server.login(from_email, 'password')  # user & password
    server.send_message(msg)
    server.quit()
    print('successfully sent the mail.')

call this function:

send_mail(to_email=['[email protected]', '[email protected]'],
          subject='hello', message='Your analysis has done!')

below may only for Chinese user:

If you use 126/163, ????, you need to set"???????", like below:

Thanks are due to whoever on SO showed me the use of accumulating data during a query.

You can use:

f.Controls[name];

Where f is your form variable. That gives you the control with name name.

Use a repository manager and install this kind of jars into it. That solves your problems at all and for all computers in your network.

I think that if you use the extension pattern used in the example for findbugs plugin & multimodule you may be able to set global properties related to absolute paths. It uses a top

example for multi module

The top level pom has an unrelated build-config project and a app-parent for the modules of the multimodule project. The app-parent uses extension to link itself to the build-config project and obtain resources from it. This is used to carry common config files to the modules. It may be a conduit for properties as well. You could write the top dir to a property file consumed by the build-config. (it seems too complex)

The problem is that a new top level must be added to the multi-module project to make this work. I tried to side step with a truly unrelated build-config project but it was kludgy and seemed brittle.

You can't declare a variable as Decimal - you have to use Variant (you can use CDec to populate it with a Decimal type though).

Use count(*)

declare 
   cnt integer;
begin
  SELECT count(*) INTO cnt
  FROM people
  WHERE person_id = my_person_id;

IF cnt > 0 THEN
  -- Do something
END IF;

Edit (for the downvoter who didn't read the statement and others who might be doing something similar)

The solution is only effective because there is a where clause on a column (and the name of the column suggests that its the primary key - so the where clause is highly effective)

Because of that where clause there is no need to use a LIMIT or something else to test the presence of a row that is identified by its primary key. It is an effective way to test this.

You can use use.

Example:

iptables -A INPUT -j LOG --log-prefix "INPUT:DROP:" --log-level 6
iptables -A INPUT -j DROP

Log Exampe:

Feb 19 14:18:06 servername kernel: INPUT:DROP:IN=eth1 OUT= MAC=aa:bb:cc:dd:ee:ff:11:22:33:44:55:66:77:88 SRC=x.x.x.x DST=x.x.x.x LEN=48 TOS=0x00 PREC=0x00 TTL=117 ID=x PROTO=TCP SPT=x DPT=x WINDOW=x RES=0x00 SYN URGP=0

Other options:

   LOG
       Turn on kernel logging of matching packets.  When this option 
       is set for a rule, the Linux kernel will print some 
       information  on  all  matching  packets
       (like most IP header fields) via the kernel log (where it can 
       be read with dmesg or syslogd(8)).  This is a "non-terminating 
       target", i.e. rule traversal
       continues at the next rule.  So if you want to LOG the packets 
       you refuse, use two separate rules with the same matching 
       criteria, first using target LOG
       then DROP (or REJECT).

       --log-level level
              Level of logging (numeric or see syslog.conf(5)).

       --log-prefix prefix
              Prefix log messages with the specified prefix; up to 29 
              letters long, and useful for distinguishing messages in 
              the logs.

       --log-tcp-sequence
              Log TCP sequence numbers. This is a security risk if the 
              log is readable by users.

       --log-tcp-options
              Log options from the TCP packet header.

       --log-ip-options
              Log options from the IP packet header.

       --log-uid
              Log the userid of the process which generated the packet.

Backup==>

Option1: To take backup along with password in cmd
1.PGPASSWORD="mypassword" pg_dump -U postgres -h localhost --inserts mydb>mydb.sql
Option2: To take backup without password in cmd
2. pg_dump -U postgres -h localhost --inserts mydb>mydb.sql
Option3: To take backup as gzip(if database is huge)
3. pg_dump -U postgres -h localhost mydb --inserts | gzip > mydb.gz

Restore:
1. psql -h localhost -d mydb -U postgres -p 5432 < mydb.sql

You may have to change the button template, this will give you a button with no frame what so ever, but also without any press or disabled effect:

    <Style x:Key="TransparentStyle" TargetType="{x:Type Button}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Background="Transparent">
                        <ContentPresenter/>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

And the button:

<Button Style="{StaticResource TransparentStyle}"/>

1) Update Devise so that it can handle Rails 4.0 by adding this line to your application's Gemfile:

gem 'devise', '3.0.0.rc' 

Then execute:

$ bundle

2) Add the old functionality of attr_accessible again to rails 4.0

Try to use attr_accessible and don't comment this out.

Add this line to your application's Gemfile:

gem 'protected_attributes'

Then execute:

$ bundle

Try:

return $this->sendRequest($uri);

Since PHP is not a pure Object-Orieneted language, it interprets sendRequest() as an attempt to invoke a globally defined function (just like nl2br() for example), but since your function is part of a class ('InstagramController'), you need to use $this to point the interpreter in the right direction.

A little addition to all the answers:

if you do something like that:

#include<stdio.h>
#include <stdlib.h>
int * foo(){
    int a = 5;
    return &a;
}
void boo(){
    int a = 7;

}
int main(){
    int * p = foo();
    boo();
    printf("%d\n",*p);
}

the output probably will be: 7

That is because after returning from foo() the stack is freed and then reused by boo(). If you deassemble the executable you will see it clearly.

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html>

Adding style="width:100%;max-width:640px" to the image tag will scale it up to the viewport width, i.e. for larger windows it will look fixed width.

Based on what I read from different sources:

An await expression does not block the thread on which it is executing. Instead, it causes the compiler to sign up the rest of the async method as a continuation on the awaited task. Control then returns to the caller of the async method. When the task completes, it invokes its continuation, and execution of the async method resumes where it left off.

To wait for a single task to complete, you can call its Task.Wait method. A call to the Wait method blocks the calling thread until the single class instance has completed execution. The parameterless Wait() method is used to wait unconditionally until a task completes. The task simulates work by calling the Thread.Sleep method to sleep for two seconds.

This article is also a good read.

The main function must be declared as a non-member function in the global namespace. This means that it cannot be a static or non-static member function of a class, nor can it be placed in a namespace (even the unnamed namespace).

The name main is not reserved in C++ except as a function in the global namespace. You are free to declare other entities named main, including among other things, classes, variables, enumerations, member functions, and non-member functions not in the global namespace.

You can declare a function named main as a member function or in a namespace, but such a function would not be the main function that designates where the program starts.

The main function cannot be declared as static or inline. It also cannot be overloaded; there can be only one function named main in the global namespace.

The main function cannot be used in your program: you are not allowed to call the main function from anywhere in your code, nor are you allowed to take its address.

The return type of main must be int. No other return type is allowed (this rule is in bold because it is very common to see incorrect programs that declare main with a return type of void; this is probably the most frequently violated rule concerning the main function).

There are two declarations of main that must be allowed:

int main()               // (1)
int main(int, char*[])   // (2)

In (1), there are no parameters.

In (2), there are two parameters and they are conventionally named argc and argv, respectively. argv is a pointer to an array of C strings representing the arguments to the program. argc is the number of arguments in the argv array.

Usually, argv[0] contains the name of the program, but this is not always the case. argv[argc] is guaranteed to be a null pointer.

Note that since an array type argument (like char*[]) is really just a pointer type argument in disguise, the following two are both valid ways to write (2) and they both mean exactly the same thing:

int main(int argc, char* argv[])
int main(int argc, char** argv)

Some implementations may allow other types and numbers of parameters; you'd have to check the documentation of your implementation to see what it supports.

main() is expected to return zero to indicate success and non-zero to indicate failure. You are not required to explicitly write a return statement in main(): if you let main() return without an explicit return statement, it's the same as if you had written return 0;. The following two main() functions have the same behavior:

int main() { }
int main() { return 0; }

There are two macros, EXIT_SUCCESS and EXIT_FAILURE, defined in <cstdlib> that can also be returned from main() to indicate success and failure, respectively.

The value returned by main() is passed to the exit() function, which terminates the program.

Note that all of this applies only when compiling for a hosted environment (informally, an environment where you have a full standard library and there's an OS running your program). It is also possible to compile a C++ program for a freestanding environment (for example, some types of embedded systems), in which case startup and termination are wholly implementation-defined and a main() function may not even be required. If you're writing C++ for a modern desktop OS, though, you're compiling for a hosted environment.

Using Underscore.js:

var myArray = [
  Object { key="11", value="1100", $$hashKey="00X"},
  Object { key="22", value="2200", $$hashKey="018"}
];
var myObj = _.object(_.pluck(myArray, 'key'), _.pluck(myArray, 'value'));

I've found this absolutely invaluable when unable to grab something in a custom class or changing id's:

driver.find_element_by_xpath("//*[contains(text(), 'Show Next Date Available')]").click()
driver.find_element_by_xpath("//*[contains(text(), 'Show Next Date Available')]").text
driver.find_element_by_xpath("//*[contains(text(), 'Available')]").text
driver.find_element_by_xpath("//*[contains(text(), 'Avail')]").text

I just stumbled onto this while searching for this answer. If you are using intellij, you can navigate to the file location, but opening the external lib folder in the project explorer, right clicking on the jar, and select Open Library Settings.

Based on John's answer, I changed the GET request to a POST request. It works, without having to change the server configuration. So I went looking how to implement this. The following pages were helpful:

jQuery Ajax POST example with PHP (Note the sanitize posted data remark) and

http://www.openjs.com/articles/ajax_xmlhttp_using_post.php

Basically, the difference is that the GET request has the url and parameters in one string and then sends null:

http.open("GET", url+"?"+params, true);
http.send(null);

whereas the POST request sends the url and the parameters in separate commands:

http.open("POST", url, true);
http.send(params);

Here is a working example:

ajaxPOST.html:

<html>
<head>
<script type="text/javascript">
    function ajaxPOSTTest() {
        try {
            // Opera 8.0+, Firefox, Safari
            ajaxPOSTTestRequest = new XMLHttpRequest();
        } catch (e) {
            // Internet Explorer Browsers
            try {
                ajaxPOSTTestRequest = new ActiveXObject("Msxml2.XMLHTTP");
            } catch (e) {
                try {
                    ajaxPOSTTestRequest = new ActiveXObject("Microsoft.XMLHTTP");
                } catch (e) {
                    // Something went wrong
                    alert("Your browser broke!");
                    return false;
                }
            }
        }

        ajaxPOSTTestRequest.onreadystatechange = ajaxCalled_POSTTest;
        var url = "ajaxPOST.php";
        var params = "lorem=ipsum&name=binny";
        ajaxPOSTTestRequest.open("POST", url, true);
        ajaxPOSTTestRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        ajaxPOSTTestRequest.send(params);
    }

    //Create a function that will receive data sent from the server
    function ajaxCalled_POSTTest() {
        if (ajaxPOSTTestRequest.readyState == 4) {
            document.getElementById("output").innerHTML = ajaxPOSTTestRequest.responseText;
        }
    }
</script>

</head>
<body>
    <button onclick="ajaxPOSTTest()">ajax POST Test</button>
    <div id="output"></div>
</body>
</html>

ajaxPOST.php:

<?php

$lorem=$_POST['lorem'];
print $lorem.'<br>';

?>

I just sent over 12,000 characters without any problems.

Think it that way, will be simpler

If you have 3 buttons and their weights are 1,3,1 accordingly, it will work like table in HTML

Provide 5 portions for that line: 1 portion for button 1, 3 portion for button 2 and 1 portion for button 1

I like the two line approach of jmh_gr.

It won't work with single digit numbers unless you put () around the portion of the command before the redirect. since 1> is a special command "Echo is On" will be redirected to the file.

This example should take care of single digit numbers but not the other special characters such as < that may be in the string.

(ECHO %strvar%)> tempfile.txt

If you are using ASP.NET, the server-side code tags in these examples below will provide the exact control ID, even if you are using Master pages.

Javascript:

document.getElementById("<%=MyControlName.ClientID%>").value;

JQuery:

$("#<%= MyControlName.ClientID %>").val();

I am not sure if I am missing here, but I think the easiest and best way to do it is using tf.keras.backend.get_value API.

print(product)
>>tf.Tensor([[12.]], shape=(1, 1), dtype=float32)
print(tf.keras.backend.get_value(product))
>>[[12.]]

I tend to agree with split suggestion.

Ive created a "tester" for your problem in perl

#!/usr/bin/perl -w


@strings = ( "1.2.3", "1.2.*", "1.*","*" );

            greg => qr/^(\*|\d+(\.\d+){0,2}(\.\*)?)$/,
            vonc => qr/^((?:\d+(?!\.\*)\.)+)(\d+)?(\.\*)?$|^(\d+)\.\*$|^(\*|\d+)$/,
            ajb => qr/^(?:(\d+)\.)?(?:(\d+)\.)?(\*|\d+)$/,
            jrudolph => qr/^(((\d+)\.)?(\d+)\.)?(\d+|\*)$/
          );

  foreach my $r (keys %regexp){
    my $reg = $regexp{$r};
    print "Using $r regexp\n";
foreach my $s (@strings){
  print "$s : ";

    if ($s =~m/$reg/){
    my ($main, $maj, $min,$rev,$ex1,$ex2,$ex3) = ("any","any","any","any","any","any","any");
    $main = $1 if ($1 && $1 ne "*") ;

The reason you're getting two rows instead of one is that you are grouping by rsp_ind in the outer query (which you did not, to my disappointment, share with us). There is nothing you can do to force one row instead of two without dealing with that GROUP BY item.

FYI dataTables requires a well formed table. It must contain <thead> and <tbody> tags, otherwise it throws this error. Also check to make sure all your rows including header row have the same number of columns.

The following will throw error (no <thead> and <tbody> tags)

<table id="sample-table">
    <tr>
        <th>title-1</th>
        <th>title-2</th>
    </tr>
    <tr>
        <td>data-1</td>
        <td>data-2</td>
    </tr>
</table>

The following will also throw an error (unequal number of columns)

<table id="sample-table">
    <thead>
        <tr>
            <th>title-1</th>
            <th>title-2</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>data-1</td>
            <td>data-2</td>
            <td>data-3</td>
        </tr>
    </tbody>
</table>

switch is very picky in the sense that the values in the switch must be a compile time constant. and also the value that's being compared must be a primitive (or string now). For this you should use an if statement.

The reason may go back to the way that C handles them in that it creates a jump table (because the values are compile time constants) and it tries to copy the same semantics by not allowing evaluated values in your cases.

A simple and easy way to position an Icon inside of an input is to use the position CSS property as shown in the code below. Note: I have simplified the code for clarity purposes.

1. Create the container surrounding the input and icon.
2. Set the container position as relative
3. Set the icon as position absolute. This will position the icon relative to the surrounding container.
4. Use either top, left, bottom, right to position the icon in the container.
5. Set the padding inside the input so the text does not overlap the icon.

#input-container {_x000D_
  position: relative;_x000D_
}_x000D_
_x000D_
#input-container > img {_x000D_
  position: absolute;_x000D_
  top: 12px;_x000D_
  left: 15px;_x000D_
}_x000D_
_x000D_
#input-container > input {_x000D_
  padding-left: 40px;_x000D_
}

<div id="input-container">_x000D_
  <img/>_x000D_
  <input/>_x000D_
</div>

There is the GeoLocation API, but browser support is rather thin on the ground at present. Most sites that care about such things use a GeoIP database (with the usual provisos about the inaccuracy of such a system). You could also look at third party services requiring user cooperation such as FireEagle.

double amount = 25.00;

NumberFormat formatter = new DecimalFormat("#0.00");

System.out.println(formatter.format(amount));

Note: The answer below was written in 2010. Here many years later, both keyCode and which are deprecated in favor of key (for the logical key) and code (for the physical placement of the key). But note that IE doesn't support code, and its support for key is based on an older version of the spec so isn't quite correct. As I write this, the current Edge based on EdgeHTML and Chakra doesn't support code either, but Microsoft is rolling out its Blink- and V8- based replacement for Edge, which presumably does/will.

Some browsers use keyCode, others use which.

If you're using jQuery, you can reliably use which as jQuery standardizes things; More here.

If you're not using jQuery, you can do this:

var key = 'which' in e ? e.which : e.keyCode;

Or alternatively:

var key = e.which || e.keyCode || 0;

...which handles the possibility that e.which might be 0 (by restoring that 0 at the end, using JavaScript's curiously-powerful || operator).

There has been a discussion here which might help: Is there a simple way to convert C++ enum to string?

UPDATE: Here#s a script for Lua which creates an operator<< for each named enum it encounters. This might need some work to make it work for the less simple cases [1]:

function make_enum_printers(s)
    for n,body in string.gmatch(s,'enum%s+([%w_]+)%s*(%b{})') do
    print('ostream& operator<<(ostream &o,'..n..' n) { switch(n){') 
    for k in string.gmatch(body,"([%w_]+)[^,]*") do
    print('  case '..k..': return o<<"'..k..'";')
    end
    print('  default: return o<<"(invalid value)"; }}')
    end
end

local f=io.open(arg[1],"r")
local s=f:read('*a')
make_enum_printers(s)

Given this input:

enum Errors
{ErrorA=0, ErrorB, ErrorC};

enum Sec {
    X=1,Y=X,foo_bar=X+1,Z
};

It produces:

ostream& operator<<(ostream &o,Errors n) { switch(n){
  case ErrorA: return o<<"ErrorA";
  case ErrorB: return o<<"ErrorB";
  case ErrorC: return o<<"ErrorC";
  default: return o<<"(invalid value)"; }}
ostream& operator<<(ostream &o,Sec n) { switch(n){
  case X: return o<<"X";
  case Y: return o<<"Y";
  case foo_bar: return o<<"foo_bar";
  case Z: return o<<"Z";
  default: return o<<"(invalid value)"; }}

So that's probably a start for you.

[1] enums in different or non-namespace scopes, enums with initializer expressions which contain a komma, etc.

not sure if it'll work in your scenario, but try adding the following to your web.config under <system.web>:

  <system.web>
    <customErrors mode="Off" />
  ...
  </system.web>

works in my instance.

First check - is the working directory the directory that the application is running in:

• Right-click on your project and select Properties.
• Click the Debug tab.
• Confirm that the Working directory is either empty or equal to the bin\debug directory.

If this isn't the problem, then ask if Autodesk.Navisworks.Timeliner.dll is requiring another DLL which is not there. If Timeliner.dll is not a .NET assembly, you can determine the required imports using the command utility DUMPBIN.

dumpbin /imports Autodesk.Navisworks.Timeliner.dll

If it is a .NET assembly, there are a number of tools that can check dependencies.

Reflector has already been mentioned, and I use JustDecompile from Telerik.

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

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

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

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

and then insert it after the loop

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

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

You can use the javascript in the second link provided by Ravi Khakhkhar or you are going to have to perform some string manipulation to convert your orginal string (as some of the special characters in your original format aren't being recognised as valid delimeters) but once you do that, you can use "new"

This is what matplotlib.pyplot.scatter is for.

As a quick example:

import matplotlib.pyplot as plt
import numpy as np

# Generate data...
t = np.linspace(0, 2 * np.pi, 20)
x = np.sin(t)
y = np.cos(t)

plt.scatter(t,x,c=y)
plt.show()

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

If you installed the command line tools separately, delete them using:

I realize this question was asked a long time ago, but I came here looking for answers and wasn't satisfied with anything I could find. I finally found the answer here:

https://www.tutorialsteacher.com/mvc/htmlhelper-dropdownlist-dropdownlistfor

To get the results from the form, use the FormCollection and then pull each individual value out by it's model name thus:

yourRecord.FieldName = Request.Form["FieldNameInModel"];

As far as I could tell it makes absolutely no difference what argument name you give to the FormCollection - use Request.Form["NameFromModel"] to retrieve it.

No, I did not dig down to see how th4e magic works under the covers. I just know it works...

I hope this helps somebody avoid the hours I spent trying different approaches before I got it working.

1. Create your shell script as login.sh in your $HOME folder.

2. Paste the following one-line script into Script Editor:

   do shell script "$HOME/login.sh"

3. Then save it as an application.

4. Finally add the application to your login items.

If you want to make the script output visual, you can swap step 2 for this:

tell application "Terminal"
  activate
  do script "$HOME/login.sh"
end tell

If multiple commands are needed something like this can be used:

tell application "Terminal"
  activate
  do script "cd $HOME"
  do script "./login.sh" in window 1
end tell

The documentation you linked actually has the answer in the link associated with the "Java class located out of the source root." Configure your source and test roots and it should work.

https://www.jetbrains.com/idea/webhelp/configuring-content-roots.html

Since you stated that these are tests you should probably go with them marked as Test Source Root instead of Source Root.

class Test
{
    Dictionary<int, string> entities;

    public string GetEntity(int code)
    {
        // java's get method returns null when the key has no mapping
        // so we'll do the same

        string val;
        if (entities.TryGetValue(code, out val))
            return val;
        else
            return null;
    }
}

An ANR happens when some long operation takes place in the "main" thread. This is the event loop thread, and if it is busy, Android cannot process any further GUI events in the application, and thus throws up an ANR dialog.

Now, in the trace you posted, the main thread seems to be doing fine, there is no problem. It is idling in the MessageQueue, waiting for another message to come in. In your case the ANR was likely a longer operation, rather than something that blocked the thread permanently, so the event thread recovered after the operation finished, and your trace went through after the ANR.

Detecting where ANRs happen is easy if it is a permanent block (deadlock acquiring some locks for instance), but harder if it's just a temporary delay. First, go over your code and look for vunerable spots and long running operations. Examples may include using sockets, locks, thread sleeps, and other blocking operations from within the event thread. You should make sure these all happen in separate threads. If nothing seems the problem, use DDMS and enable the thread view. This shows all the threads in your application similar to the trace you have. Reproduce the ANR, and refresh the main thread at the same time. That should show you precisely whats going on at the time of the ANR

In your example, you prepended your source string with AccountKey= but not your target string.

$c = $c -replace 'AccountKey=eKkij32jGEIYIEqAR5RjkKgf4OTiMO6SAyF68HsR/Zd/KXoKvSdjlUiiWyVV2+OUFOrVsd7jrzhldJPmfBBpQA==','AccountKey=DdOegAhDmLdsou6Ms6nPtP37bdw6EcXucuT47lf9kfClA6PjGTe3CfN+WVBJNWzqcQpWtZf10tgFhKrnN48lXA=='

By not including that in the target string, the resulting string will remove AccountKey= instead of replacing it. You correctly do this with the AccountName= example, which seems to support this conclusion since it is not giving you any problems. If you really mean to have that prepended, then this may resolve your issue.

1. Delete the app from the device.
2. Edit the file (YourAppName -> android -> app -> build.gradle) enter the line below on the defaultConfig field

multiDexEnabled true

defaultConfig {
    multiDexEnabled true //this is the line you need to enter
    applicationId "xxxxxx"
    minSdkVersion xxxxx
    targetSdkVersion xxxxx
    versionCode xx
    versionName "xx"
}

3. rebuild the app

If you are using a database that supports map-reduce, like couchdb, storing tags in a plain text field or list field is indeed the best way. Example:

tagcloud: {
  map: function(doc){ 
    for(tag in doc.tags){ 
      emit(doc.tags[tag],1) 
    }
  }
  reduce: function(keys,values){
    return values.length
  }
}

Running this with group=true will group the results by tag name, and even return a count of the number of times that tag was encountered. It's very similar to counting the occurrences of a word in text.

Actually, you should set a config on your Terminal, when your Terminal is up press ?+, then you will see below screen:

Then press shell tab and you will see below screen:

Now select Close if the shell exited cleanly for When the shell exits.

By the above config each time with exit command the Terminal will close but won't quit.

Element.children returns only element children, while Node.childNodes returns all node children. Note that elements are nodes, so both are available on elements.

I believe childNodes is more reliable. For example, MDC (linked above) notes that IE only got children right in IE 9. childNodes provides less room for error by browser implementors.
