For all to those having problems with this i did this tutorial:

How to install Imagemagick and Php module Imagick on ubuntu?

i did this 7 simple steps:

Update libraries, and packages

apt-get update

Remove obsolete things

apt-get autoremove

For the libraries of ImageMagick

apt-get install libmagickwand-dev

for the core class Imagick

apt-get install imagemagick

For create the binaries, and conections in beetween

pecl install imagick

Append the extension to your php.ini

echo "extension=imagick.so" >> /etc/php5/apache2/php.ini

Restart Apache

service apache2 restart

I found a problem. PHP searches for .so files in a folder called /usr/lib/php5/20100525, and the imagick.so is stored in a folder called /usr/lib/php5/20090626. So you have to copy the file to that folder.

Use the select list object, to identify its own selected options index. From there - grab the inner HTML of that index. And now you have the text string of that option.

<select onchange="alert(this.options[this.selectedIndex].innerHTML);">
       <option value="">Select Actions</option>
       <option value="1">Print PDF</option>
       <option value="2">Send Message</option>
       <option value="3">Request Review</option>
       <option value="4">Other Possible Actions</option>
    </select>

What you can do, is open up a WebSocket connection when the page loads, optionally send data through the WebSocket identifying the current user, and check when that connection is closed on the server.

Something like this will add a button and let you use it to clear the values

<div>           
<input type="text" id="textfield1" size="5"/>         
</div>

<div>          
<input type="text" id="textfield2" size="5"/>           
</div>

<div>
    <input type="button" onclick="clearFields()" value="Clear">
</div>


<script type="text/javascript">
function clearFields() {
    document.getElementById("textfield1").value=""
    document.getElementById("textfield2").value=""
}
</script>

Here is what I use for this situation as a module (in my formhelper.js):

define(function(){
    FormHelper = {};

    FormHelper.parseForm = function($form){
        var serialized = $form.serializeArray();
        var s = '';
        var data = {};
        for(s in serialized){
            data[serialized[s]['name']] = serialized[s]['value']
        }
        return JSON.stringify(data);
    }

    return FormHelper;
});

It kind of sucks that I can't seem to find another way to do what I want to do.

This does return this JSON for me:

{"first_name":"John","last_name":"Smith","age":"30"}

Delay operates on a queue. and as far as i know css manipulation (other than through animate) is not queued.

You can use jquery's load function here.

$("#your_element_id").load("file_name.html");

If you need more info, here is the link.

If you are using git, this searches all of the tracked files:

git grep -L "foo"

and you can search in a subset of tracked files if you have ** subdirectory globbing turned on (shopt -s globstar in .bashrc, see this):

git grep -L "foo" -- **/*.cpp

I would vote against display: inline-block since its not supported across browsers, IE < 8 specifically.

.wrapper {
    width:500px; /* Adjust to a total width of both .left and .right */
    margin: 0 auto;
}
.left {
    float: left;
    width: 49%; /* Not 50% because of 1px border. */
    border: 1px solid #000;
}
.right {
    float: right;
    width: 49%; /* Not 50% because of 1px border. */
    border: 1px solid #F00;
}

<div class="wrapper">
    <div class="left">Div 1</div>
    <div class="right">Div 2</div>
</div>

EDIT: If no spacing between the cells is desired just change both .left and .right to use float: left;

Step 1:
Go to a fiddle page like jsfiddle.net/oskar/v5893p61

Step 2:
Add '/show' at the end of the URL, like jsfiddle.net/oskar/v5893p61/show

Step 3:
Right click on the page and click on the View frame source. You will get the HTML code including CSS in tag and Javascript (js) in tag. [Also source link of all library will be added]. See screenshot

Step 4:
Now you can save the source code in a .html file.

You can solve it by adding simply: df['C'] = df['A'] + df['B']

A simple read

var getCookie = function (name) {
    var valueStart = document.cookie.indexOf(name + "=") + name.length + 1;
    var valueEnd = document.cookie.indexOf(";", valueStart); 
    return document.cookie.slice(valueStart, valueEnd)
}

It's this easy:

update my_table
set path = replace(path, 'oldstring', 'newstring')

If you are experiencing errors during PKG installation following the accepted answer, I will give you another procedure that worked for me (please note the little changes to xar, cpio and mkbom commands):

mkdir Foo
cd Foo
xar -xf ../Foo.pkg
cd foo.pkg
cat Payload | gunzip -dc | cpio -i
# edit Foo.app/*
rm Payload
find ./Foo.app | cpio -o --format odc --owner 0:80 | gzip -c > Payload
mkbom -u 0 -g 80 Foo.app Bom # or edit Bom
# edit PackageInfo
rm -rf Foo.app
cd ..
xar --compression none -cf ../Foo-new.pkg

The resulted PKG will have no compression, cpio now uses odc format and specify the owner of the file as well as mkbom.

When running into this error and reviewing my dataset which appeared to have no missing data, I discovered that a few of my entries had the special character "#" which derailed importing the data. Once I removed the "#" from the offending cells, the data imported without issue.

Answer is Objective C

if (player.timeControlStatus == AVPlayerTimeControlStatusPlaying) {
    //player is playing
}
else if (player.timeControlStatus == AVPlayerTimeControlStatusPaused) {
    //player is pause
}
else if (player.timeControlStatus == AVPlayerTimeControlStatusWaitingToPlayAtSpecifiedRate) {
    //player is waiting to play
}

found interesting cmd in Sed-Onliners - Delete last 3 lines - fnd it perfect for another way to skin the cat (okay not) but idea:

 #!/bin/bash
 # sed cmd chng #2 to value file wish to retain

 cd /opt/depot 

 ls -1 MyMintFiles*.zip > BigList
 sed -n -e :a -e '1,2!{P;N;D;};N;ba' BigList > DeList

 for i in `cat DeList` 
 do 
 echo "Deleted $i" 
 rm -f $i  
 #echo "File(s) gonzo " 
 #read junk 
 done 
 exit 0

I was using a .Net Core 2.1 API with the [FromBody] attribute and I had to use the following solution to successfully Post to it:

_apiClient =  new HttpClient();
_apiClient.BaseAddress = new Uri(<YOUR API>);
var MyObject myObject = new MyObject(){
    FirstName = "Me",
    LastName = "Myself"
};

var stringified = JsonConvert.SerializeObject(myObject);
var result = await _apiClient.PostAsync("api/appusers", new StringContent(stringified, Encoding.UTF8, "application/json"));

To trim specific char, you can use:

String s = s.replaceAll("^(,|\\s)*|(,|\\s)*$", "")

Here will strip leading and trailing space and comma.

i guess that you have a different class name in p1.java

You call PowerShell functions without the parentheses and without using the comma as a separator. Try using:

test "ABC" "DEF"

In PowerShell the comma (,) is an array operator, e.g.

$a = "one", "two", "three"

It sets $a to an array with three values.

Add a trigger in database:

DELIMITER //
CREATE TRIGGER update_user_password 
  BEFORE UPDATE ON users
  FOR EACH ROW
    BEGIN
      IF OLD.password <> NEW.password THEN
        SET NEW.password_changed_on = NOW();
      END IF;
    END //
DELIMITER ;

The password changed time will update only when password column is changed.

$(Split-Path "D:\Server\User\CUST\MEA\Data\In\Files\CORRECTED\CUST_MEAFile.csv" -leaf)

>>> import re
>>> re.sub("[^0-9]", "", "sdkjh987978asd098as0980a98sd")
'987978098098098'

The code you posted is wrong.

You shouldn't make multiple calls to DateTime.Today. If you happen to run that code just as the date changes you could get completely wrong results. For example if you ran it on December 31st 2011 you might get "2011-1-1".

Use a single call to DateTime.Today then use ToString with an appropriate format string to format the date as you desire.

string result = DateTime.Today.AddDays(-1).ToString("yyyy-MM-dd");

Additionally, if you have multiple columns to insert and want to check if they exists or not use the following code

Insert Into [Competitors] (cName, cCity, cState)
Select cName, cCity, cState from 
(
    select new.* from 
    (
        select distinct cName, cCity, cState 
        from [Competitors] s, [City] c, [State] s
    ) new
    left join 
    (   
        select distinct cName, cCity, cState 
        from [Competitors] s
    ) existing
    on new.cName = existing.cName and new.City = existing.City and new.State = existing.State
    where existing.Name is null  or existing.City is null or existing.State is null
)

Please try this one works for me:

<ImageView android:id="@+id/image_view"     
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:adjustViewBounds="true"  
  android:maxWidth="60dp" 
  android:layout_gravity="center" 
  android:maxHeight="60dp"  
  android:scaleType="fitCenter"  
  android:src="@drawable/icon"  
  /> 

try this grid.getView().refresh();

You can use

 rspec spec/controllers/groups_controller_spec.rb:<line_number>

line number should be line number of 'describe' or 'it' lines so that it will run tests present in that particular block. instead it will execute all the lines next to line_number.

also you can create block with custom name and then can execute those blocks only.

new Buffer(number)            // Old
Buffer.alloc(number)          // New

new Buffer(string)            // Old
Buffer.from(string)           // New

new Buffer(string, encoding)  // Old
Buffer.from(string, encoding) // New

new Buffer(...arguments)      // Old
Buffer.from(...arguments)     // New

Note that Buffer.alloc() is also faster on the current Node.js versions than new Buffer(size).fill(0), which is what you would otherwise need to ensure zero-filling.

Yeah think of signing data as giving it your own wax stamp that nobody else has. It is done to achieve integrity and non-repudiation. Encryption is so no-one else can see the data. This is done to achieve confidentiality. See wikipedia http://en.wikipedia.org/wiki/Information_security#Key_concepts

A signature is a hash of your message signed using your private key.

I had the same issue. I came up with a simple solution. Use fragment .replace instead of fragment .add. Replacing fragment doing the same thing as adding fragment and then removing it manually.

getFragmentManager().beginTransaction().replace(fragment).commit();

instead of

getFragmentManager().beginTransaction().add(fragment).commit();

So I just solved my own "SMTP connection failure" error and I wanted to post the solution just in case it helps anyone else.

I used the EXACT code given in the PHPMailer example gmail.phps file. It worked simply while I was using MAMP and then I got the SMTP connection error once I moved it on to my personal server.

All of the Stack Overflow answers I read, and all of the troubleshooting documentation from PHPMailer said that it wasn't an issue with PHPMailer. That it was a settings issue on the server side. I tried different ports (587, 465, 25), I tried 'SSL' and 'TLS' encryption. I checked that openssl was enabled in my php.ini file. I checked that there wasn't a firewall issue. Everything checked out, and still nothing.

The solution was that I had to remove this line:

$mail->isSMTP();

Now it all works. I don't know why, but it works. The rest of my code is copied and pasted from the PHPMailer example file.

You need to change the password directly in the database because at mysql the users and their profiles are saved in the database.

So there are several ways. At phpMyAdmin you simple go to user admin, choose root and change the password.

It will only push the new commits. It won't push the whole "master" branch. That is part of the benefit of working with a Distributed Version Control System. Git figures out what is actually needed and only pushes those pieces. If the branch you are on has been changed and pushed by someone else you'll need to pull first. Then push your commits.

The functions getElementById and getElementsByClassName are very specific, while querySelector and querySelectorAll are more elaborate. My guess is that they will actually have a worse performance.

Also, you need to check for the support of each function in the browsers you are targetting. The newer it is, the higher probability of lack of support or the function being "buggy".

You have two syntax options:

Option 1

CREATE TABLE Table1 (
    id int identity(1, 1) not null,
    LongIntColumn1 int,
    CurrencyColumn money
)

CREATE TABLE Table2 (
    id int identity(1, 1) not null,
    LongIntColumn2 int,
    CurrencyColumn2 money
)

INSERT INTO Table1 VALUES(12, 12.00)
INSERT INTO Table1 VALUES(11, 13.00)

INSERT INTO Table2
SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1 FROM Table1 GROUP BY LongIntColumn1

Option 2

CREATE TABLE Table1 (
    id int identity(1, 1) not null,
    LongIntColumn1 int,
    CurrencyColumn money
)

INSERT INTO Table1 VALUES(12, 12.00)
INSERT INTO Table1 VALUES(11, 13.00)


SELECT LongIntColumn1, Avg(CurrencyColumn) as CurrencyColumn1
INTO Table2
FROM Table1
GROUP BY LongIntColumn1

Bear in mind that Option 2 will create a table with only the columns on the projection (those on the SELECT).

There are two ways:

The best way is to remove the <p> altogether. It is acting according to specification when it adds space.

Alternately, use CSS to style the <p>. Something like:

ul li p {
    padding: 0;
    margin: 0;
    display: inline;
}

Just like you said

select * from tbl where statusid is null

or

select * from tbl where statusid is not null

If your statusid is not null, then it will be selected just fine when you have an actual value, no need for any "if" logic if that is what you were thinking

select * from tbl where statusid = 123 -- the record(s) returned will not have null statusid

if you want to select where it is null or a value, try

select * from tbl where statusid = 123 or statusid is null

You can also directly query your DataFrame for this information.

rpt.query('STK_ID in (600809,600141,600329)')

Or similarly search for ranges:

rpt.query('60000 < STK_ID < 70000')

Here is PostgreSQL example without trigger if someone need it on PostgreSQL:

CREATE SEQUENCE messages_seq;

 CREATE TABLE IF NOT EXISTS messages (
    id CHAR(20) NOT NULL DEFAULT ('message_' || nextval('messages_seq')),
    name CHAR(30) NOT NULL,
);

ALTER SEQUENCE messages_seq OWNED BY messages.id;

The standard approach is to give the centered element fixed dimensions, and place it absolutely:

<div class='fullscreenDiv'>
    <div class="center">Hello World</div>
</div>?

.center {
    position: absolute;
    width: 100px;
    height: 50px;
    top: 50%;
    left: 50%;
    margin-left: -50px; /* margin is -0.5 * dimension */
    margin-top: -25px; 
}?

MySQL solution:

select Name from Employee order by Name ;

Order by will order the names from a to z.

Found the following options useful to provide all the files for a self signed postgres instance

psql "host={hostname} sslmode=prefer sslrootcert={ca-cert.pem} sslcert={client-cert.pem} sslkey={client-key.pem} port={port} user={user} dbname={db}"

This post itself is not a direct answer to the question. What it is instead is a data-driven extensible benchmark that can be used to compare many of the answers (and variations of utilizing new features added in later, more modern, versions of Python) that have been posted to this question — and should therefore be helpful in determining which has the best performance.

In a few cases I've modified the code in the referenced answer to make it compatible with the benchmark framework.

There's not really any "raw string"; there are raw string literals, which are exactly the string literals marked by an 'r' before the opening quote.

A "raw string literal" is a slightly different syntax for a string literal, in which a backslash, \, is taken as meaning "just a backslash" (except when it comes right before a quote that would otherwise terminate the literal) -- no "escape sequences" to represent newlines, tabs, backspaces, form-feeds, and so on. In normal string literals, each backslash must be doubled up to avoid being taken as the start of an escape sequence.

This syntax variant exists mostly because the syntax of regular expression patterns is heavy with backslashes (but never at the end, so the "except" clause above doesn't matter) and it looks a bit better when you avoid doubling up each of them -- that's all. It also gained some popularity to express native Windows file paths (with backslashes instead of regular slashes like on other platforms), but that's very rarely needed (since normal slashes mostly work fine on Windows too) and imperfect (due to the "except" clause above).

r'...' is a byte string (in Python 2.*), ur'...' is a Unicode string (again, in Python 2.*), and any of the other three kinds of quoting also produces exactly the same types of strings (so for example r'...', r'''...''', r"...", r"""...""" are all byte strings, and so on).

Not sure what you mean by "going back" - there is no intrinsically back and forward directions, because there's no raw string type, it's just an alternative syntax to express perfectly normal string objects, byte or unicode as they may be.

And yes, in Python 2.*, u'...' is of course always distinct from just '...' -- the former is a unicode string, the latter is a byte string. What encoding the literal might be expressed in is a completely orthogonal issue.

E.g., consider (Python 2.6):

>>> sys.getsizeof('ciao')
28
>>> sys.getsizeof(u'ciao')
34

The Unicode object of course takes more memory space (very small difference for a very short string, obviously ;-).

Yes, this can be done via javascript feature detection ( or browser detection , e.g. Modernizr ) . Then, use yepnope.js to load required resources ( JS and/or CSS )

An "emulator" is a term for a software-based hardware-simulator, but in general the two are synonyms.

use this filter nav_menu_css_class as shown below

function add_classes_on_li($classes, $item, $args) {
    $classes[] = 'nav-item';
    return $classes;
}
add_filter('nav_menu_css_class','add_classes_on_li',1,3);

UPDATE

To use this filter with specific menu

if ( 'main-menu' === $args->theme_location ) { //replace main-menu with your menu
    $classes[] = "nav-item"; 
}

(Another solution using pivot_longer & pivot_wider from latest Tidyr update)

409 Conflict could be an acceptable solution.

According to: https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

The request could not be completed due to a conflict with the current state of the resource. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request. The response body SHOULD include enough information for the user to recognize the source of the conflict. Ideally, the response entity would include enough information for the user or user agent to fix the problem; however, that might not be possible and is not required.

The doc continues with an example:

Conflicts are most likely to occur in response to a PUT request. For example, if versioning were being used and the entity being PUT included changes to a resource which conflict with those made by an earlier (third-party) request, the server might use the 409 response to indicate that it can't complete the request. In this case, the response entity would likely contain a list of the differences between the two versions in a format defined by the response Content-Type.

In my case, I would like to PUT a string, that must be unique, to a database via an API. Before adding it to the database, I am checking that it is not already in the database.

If it is, I will return "Error: The string is already in the database", 409.

I believe this is what the OP wanted: an error code suitable for when the data does not pass the server's criteria.

Consider following code

<ul id="myTask">
  <li>Coding</li>
  <li>Answering</li>
  <li>Getting Paid</li>
</ul>

Now, here goes the difference

// Remove the myTask item when clicked.
$('#myTask').children().click(function () {
  $(this).remove()
});

Now, what if we add a myTask again?

$('#myTask').append('<li>Answer this question on SO</li>');

Clicking this myTask item will not remove it from the list, since it doesn't have any event handlers bound. If instead we'd used .on, the new item would work without any extra effort on our part. Here's how the .on version would look:

$('#myTask').on('click', 'li', function (event) {
  $(event.target).remove()
});

Summary:

The difference between .on() and .click() would be that .click() may not work when the DOM elements associated with the .click() event are added dynamically at a later point while .on() can be used in situations where the DOM elements associated with the .on() call may be generated dynamically at a later point.

I've gotten same problem. The servers logs showed:

DEBUG: <-- origin: null

I've investigated that and it occurred that this is not populated when I've been calling from file from local drive. When I've copied file to the server and used it from server - the request worked perfectly fine

Looks like the solution as.numeric(levels(f))[f] no longer work with R 4.0.

Alternative solution:

factor2number <- function(x){
    data.frame(levels(x), 1:length(levels(x)), row.names = 1)[x, 1]
}

factor2number(yourFactor)

Neither Glide nor Picasso is perfect. The way Glide loads an image to memory and do the caching is better than Picasso which let an image loaded far faster. In addition, it also helps preventing an app from popular OutOfMemoryError. GIF Animation loading is a killing feature provided by Glide. Anyway Picasso decodes an image with better quality than Glide.

Which one do I prefer? Although I use Picasso for such a very long time, I must admit that I now prefer Glide. But I would recommend you to change Bitmap Format to ARGB_8888 and let Glide cache both full-size image and resized one first. The rest would do your job great!

• Method count of Picasso and Glide are at 840 and 2678 respectively.
• Picasso (v2.5.1)'s size is around 118KB while Glide (v3.5.2)'s is around 430KB.
• Glide creates cached images per size while Picasso saves the full image and process it, so on load it shows faster with Glide but uses more memory.
• Glide use less memory by default with RGB_565.

+1 For Picasso Palette Helper.

There is a post that talk a lot about Picasso vs Glide post

A one-line version of this excellent answer to plot the line of best fit is:

plt.plot(np.unique(x), np.poly1d(np.polyfit(x, y, 1))(np.unique(x)))

Using np.unique(x) instead of x handles the case where x isn't sorted or has duplicate values.

It sounds like it's just a compiler warning.

Usage of scanf_s prevents possible buffer overflow.
See: http://code.wikia.com/wiki/Scanf_s

Good explanation as to why scanf can be dangerous: Disadvantages of scanf

So as suggested, you can try replacing scanf with scanf_s or disable the compiler warning.

Use:

byte[] data = Base64.encode(base64str);

Encoding converts to Base64

You would need to reference commons codec from your project in order for that code to work.

For java8:

import java.util.Base64

You can use stri_paste function with collapse parameter from stringi package like this:

stri_paste(letters, collapse='')
## [1] "abcdefghijklmnopqrstuvwxyz" 

And some benchmarks:

require(microbenchmark)
test <- stri_rand_lipsum(100)
microbenchmark(stri_paste(test, collapse=''), paste(test,collapse=''), do.call(paste, c(as.list(test), sep="")))
Unit: microseconds
                                      expr     min       lq     mean   median       uq     max neval
           stri_paste(test, collapse = "") 137.477 139.6040 155.8157 148.5810 163.5375 226.171   100
                paste(test, collapse = "") 404.139 406.4100 446.0270 432.3250 442.9825 723.793   100
do.call(paste, c(as.list(test), sep = "")) 216.937 226.0265 251.6779 237.3945 264.8935 405.989   100

Okay, I found spencerlyon2's answer working. However, in case anybody would find himself/herself not knowing what to do with that one line, I had to do it this way:

beingsaved = plt.figure()

# Some scatter plots
plt.scatter(X_1_x, X_1_y)
plt.scatter(X_2_x, X_2_y)

beingsaved.savefig('destination_path.eps', format='eps', dpi=1000)

Just rename the .war into .jar and unzip it using Winrar (or any other archive manager).

This gives me the same error as trying to split the list up and zip it. ValueError: dictionary update sequence element #0 has length 1916; 2 is required

THAT is your actual question.

The answer is that the elements of your list are not what you think they are. If you type myList[0] you will find that the first element of your list is not a two-tuple, e.g. ('A', 1), but rather a 1916-length iterable.

Once you actually have a list in the form you stated in your original question (myList = [('A',1),('B',2),...]), all you need to do is dict(myList).

Here I have a simple solution inspired by Ray's answer. This should be sufficient to identify any form of number.

This solution can also be easily modified if you want only positive numbers, integer values or values accurate to a maximum number of decimal places, etc.

As suggested in Ray's answer, you need to first add a PreviewTextInput event:

<TextBox PreviewTextInput="TextBox_OnPreviewTextInput"/>

Then put the following in the code behind:

private void TextBox_OnPreviewTextInput(object sender, TextCompositionEventArgs e)
{
    var textBox = sender as TextBox;
    // Use SelectionStart property to find the caret position.
    // Insert the previewed text into the existing text in the textbox.
    var fullText = textBox.Text.Insert(textBox.SelectionStart, e.Text);

    double val;
    // If parsing is successful, set Handled to false
    e.Handled = !double.TryParse(fullText, out val);
}

To invalid whitespace, we can add NumberStyles:

using System.Globalization;

private void TextBox_OnPreviewTextInput(object sender, TextCompositionEventArgs e)
{
    var textBox = sender as TextBox;
    // Use SelectionStart property to find the caret position.
    // Insert the previewed text into the existing text in the textbox.
    var fullText = textBox.Text.Insert(textBox.SelectionStart, e.Text);

    double val;
    // If parsing is successful, set Handled to false
    e.Handled = !double.TryParse(fullText, 
                                 NumberStyles.AllowDecimalPoint | NumberStyles.AllowLeadingSign, 
                                 CultureInfo.InvariantCulture,
                                 out val);
}

Old way of doing it. Many might hate this way of doing but i still many time find this is still better in my perspective.

Input:

var records = [{
    "empid":1,
    "fname": "X",
    "lname": "Y"
},
{
    "empid":2,
    "fname": "A",
    "lname": "Y"
},
{
    "empid":3,
    "fname": "B",
    "lname": "Y"
},
{
    "empid":4,
    "fname": "C",
    "lname": "Y"
},
{
    "empid":5,
    "fname": "C",
    "lname": "Y"
}
]

var newArr = [1,4,5];

Code:

var newObj = [];
for(var a = 0 ; a < records.length ; a++){
 if(newArr.indexOf(records[a].empid) > -1){
  newObj.push(records[a]);
 }
}

The indexOf() method returns the first index at which a given element can be found in the array, or -1 if it is not present.

Reference - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/indexOf

Output:

[{
    "empid": 1,
    "fname": "X",
    "lname": "Y"
}, {
    "empid": 4,
    "fname": "C",
    "lname": "Y"
}, {
    "empid": 5,
    "fname": "C",
    "lname": "Y"
}]

}

You can use String formatting for the double type. Here is an example:

double val = 58.6547;
String.Format("{0:0.##}", val);      
//Output: "58.65"

double val = 58.6;
String.Format("{0:0.##}", val);      
//Output: "58.6"

double val = 58.0;
String.Format("{0:0.##}", val);      
//Output: "58"

Let me know if this doesn't help.

"react-router-dom": "^5.0.0",

you do not need to add any additional module, just in your component that has a url address like this:

http://localhost:3000/#/?authority'

you can try the following simple code:

    const search =this.props.location.search;
    const params = new URLSearchParams(search);
    const authority = params.get('authority'); //

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors at your server side.

You can fetch request using mode: 'cors'. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.

So in both condition you need to configure cors in your server or you need to use custom proxy server.

<form class="form-inline">
  <div class="form-group">
    <label class="sr-only" for="exampleInputEmail3">Email address</label>
    <input type="email" class="form-control" id="exampleInputEmail3" placeholder="Email">
  </div>
  <button type="submit" class="btn btn-default">Sign in</button>
</form>

In my case I use chrono and c function localtime_r which is thread-safe (in opposition to std::localtime).

#include <iostream>
#include <chrono>
#include <ctime>
#include <time.h>
#include <iomanip>


int main() {
  std::chrono::system_clock::time_point now = std::chrono::system_clock::now();
  std::time_t currentTime = std::chrono::system_clock::to_time_t(now);
  std::chrono::milliseconds now2 = std::chrono::duration_cast<std::chrono::milliseconds>(now.time_since_epoch());
  struct tm currentLocalTime;
  localtime_r(&currentTime, &currentLocalTime);
  char timeBuffer[80];
  std::size_t charCount { std::strftime( timeBuffer, 80,
                                         "%b %d %T",
                                          &currentLocalTime)
                         };

  if (charCount == 0) return -1;

  std::cout << timeBuffer << "." << std::setfill('0') << std::setw(3) << now2.count() % 1000 << std::endl;
  return 0;
}

UPDATE 2018 FOR JQUERY 3 AND LATER

I know this is an old question but none of the above solutions worked for me. Here is the solution that worked:

//I only created this function as I am making many ajax calls with different urls and appending the result to different divs
function makeAjaxCall(requestType, urlTo, resultAreaId){
        var jqxhr = $.ajax({
            type: requestType,
            url: urlTo
        });
        //this section is executed when the server responds with no error 
        jqxhr.done(function(){

        });
        //this section is executed when the server responds with error
        jqxhr.fail(function(){

        })
        //this section is always executed
        jqxhr.always(function(){
            console.log("getting header " + jqxhr.getResponseHeader('testHeader'));
        });
    }

memdump

There is a memcdump (sometimes memdump) command for that (part of libmemcached-tools), e.g.:

memcdump --servers=localhost

which will return all the keys.

memcached-tool

In the recent version of memcached there is also memcached-tool command, e.g.

memcached-tool localhost:11211 dump | less

which dumps all keys and values.

See also:

• What's the simplest way to get a dump of all memcached keys into a file?
• How do I view the data in memcache?

Have you tried it?

If you do:

var HI = 'Hello World';

In global.js. And then do:

alert(HI);

In js1.js it will alert it fine. You just have to include global.js prior to the rest in the HTML document.

The only catch is that you have to declare it in the window's scope (not inside any functions).

You could just nix the var part and create them that way, but it's not good practice.

It's worth noting also that the yank registers are the same as the macro buffers. In other words, you can simply write out your whole command in your document (including your pasted snippet), then "by to yank it to the b register, and then run it with @b.

Regarding the internal structure of a Python long, check sys.int_info (or sys.long_info for Python 2.7).

>>> import sys
>>> sys.int_info
sys.int_info(bits_per_digit=30, sizeof_digit=4)

Python either stores 30 bits into 4 bytes (most 64-bit systems) or 15 bits into 2 bytes (most 32-bit systems). Comparing the actual memory usage with calculated values, I get

>>> import math, sys
>>> a=0
>>> sys.getsizeof(a)
24
>>> a=2**100
>>> sys.getsizeof(a)
40
>>> a=2**1000
>>> sys.getsizeof(a)
160
>>> 24+4*math.ceil(100/30)
40
>>> 24+4*math.ceil(1000/30)
160

There are 24 bytes of overhead for 0 since no bits are stored. The memory requirements for larger values matches the calculated values.

If your numbers are so large that you are concerned about the 6.25% unused bits, you should probably look at the gmpy2 library. The internal representation uses all available bits and computations are significantly faster for large values (say, greater than 100 digits).

I used this to retrieve data from MySql Database:

AccessText a = new AccessText();    
a.Text=reader[1].ToString();       // MySql reader
a.Width = 70;
a.TextWrapping = TextWrapping.WrapWithOverflow;
labels[i].Content = a;

Here is my solutions; It is my getView() in BaseAdapter subclass:

public View getView(int position, View convertView, ViewGroup parent)
{
    if(convertView==null)
    {
        convertView=inflater.inflate(R.layout.list_view, parent,false);
        System.out.println("In");
    }
    convertView.setMinimumHeight(100);
    return convertView;
}

Here i have set ListItem's minimum height to 100;

You can also dynamically create a class by using DynamicObject.

public class DynamicClass : DynamicObject
{
    private Dictionary<string, KeyValuePair<Type, object>> _fields;

    public DynamicClass(List<Field> fields)
    {
        _fields = new Dictionary<string, KeyValuePair<Type, object>>();
        fields.ForEach(x => _fields.Add(x.FieldName,
            new KeyValuePair<Type, object>(x.FieldType, null)));
    }

    public override bool TrySetMember(SetMemberBinder binder, object value)
    {
        if (_fields.ContainsKey(binder.Name))
        {
            var type = _fields[binder.Name].Key;
            if (value.GetType() == type)
            {
                _fields[binder.Name] = new KeyValuePair<Type, object>(type, value);
                return true;
            }
            else throw new Exception("Value " + value + " is not of type " + type.Name);
        }
        return false;
    }

    public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        result = _fields[binder.Name].Value;
        return true;
    }
}

I store all class fields in a dictionary _fields together with their types and values. The both methods are to can get or set value to some of the properties. You must use the dynamic keyword to create an instance of this class.

The usage with your example:

var fields = new List<Field>() { 
    new Field("EmployeeID", typeof(int)),
    new Field("EmployeeName", typeof(string)),
    new Field("Designation", typeof(string)) 
};

dynamic obj = new DynamicClass(fields);

//set
obj.EmployeeID = 123456;
obj.EmployeeName = "John";
obj.Designation = "Tech Lead";

obj.Age = 25;             //Exception: DynamicClass does not contain a definition for 'Age'
obj.EmployeeName = 666;   //Exception: Value 666 is not of type String

//get
Console.WriteLine(obj.EmployeeID);     //123456
Console.WriteLine(obj.EmployeeName);   //John
Console.WriteLine(obj.Designation);    //Tech Lead

Edit: And here is how looks my class Field:

public class Field
{
    public Field(string name, Type type)
    {
        this.FieldName = name;
        this.FieldType = type;
    }

    public string FieldName;

    public Type FieldType;
}

Simply type the command:

$ gdb <Binary> <codeDump>

Or

$ gdb <binary>

$ gdb) core <coreDump>

There isn't any need to provide any command line argument. The code dump generated due to an earlier exercise.

Yes. You'd use the urllib2 module, and encode using the multipart/form-data content type. Here is some sample code to get you started -- it's a bit more than just file uploading, but you should be able to read through it and see how it works:

user_agent = "image uploader"
default_message = "Image $current of $total"

import logging
import os
from os.path import abspath, isabs, isdir, isfile, join
import random
import string
import sys
import mimetypes
import urllib2
import httplib
import time
import re

def random_string (length):
    return ''.join (random.choice (string.letters) for ii in range (length + 1))

def encode_multipart_data (data, files):
    boundary = random_string (30)

    def get_content_type (filename):
        return mimetypes.guess_type (filename)[0] or 'application/octet-stream'

    def encode_field (field_name):
        return ('--' + boundary,
                'Content-Disposition: form-data; name="%s"' % field_name,
                '', str (data [field_name]))

    def encode_file (field_name):
        filename = files [field_name]
        return ('--' + boundary,
                'Content-Disposition: form-data; name="%s"; filename="%s"' % (field_name, filename),
                'Content-Type: %s' % get_content_type(filename),
                '', open (filename, 'rb').read ())

    lines = []
    for name in data:
        lines.extend (encode_field (name))
    for name in files:
        lines.extend (encode_file (name))
    lines.extend (('--%s--' % boundary, ''))
    body = '\r\n'.join (lines)

    headers = {'content-type': 'multipart/form-data; boundary=' + boundary,
               'content-length': str (len (body))}

    return body, headers

            logging.debug ('Testing file_path %r', file_path)
            if file_matcher.search (file_path):

        else:
            logging.error ('No such path: %r' % path)

    logging.info ('Done!')

Even after this my code is working fine , so i just removed all warning messages with this statement at line 1 .

<?php error_reporting(E_ERROR); ?>

Using requests and json makes it simple.

1. Call the API
2. Assuming the API returns a JSON, parse the JSON object into a Python dict using json.loads function
3. Loop through the dict to extract information.

Requests module provides you useful function to loop for success and failure.

if(Response.ok): will help help you determine if your API call is successful (Response code - 200)

Response.raise_for_status() will help you fetch the http code that is returned from the API.

Below is a sample code for making such API calls. Also can be found in github. The code assumes that the API makes use of digest authentication. You can either skip this or use other appropriate authentication modules to authenticate the client invoking the API.

#Python 2.7.6
#RestfulClient.py

import requests
from requests.auth import HTTPDigestAuth
import json

# Replace with the correct URL
url = "http://api_url"

# It is a good practice not to hardcode the credentials. So ask the user to enter credentials at runtime
myResponse = requests.get(url,auth=HTTPDigestAuth(raw_input("username: "), raw_input("Password: ")), verify=True)
#print (myResponse.status_code)

# For successful API call, response code will be 200 (OK)
if(myResponse.ok):

    # Loading the response data into a dict variable
    # json.loads takes in only binary or string variables so using content to fetch binary content
    # Loads (Load String) takes a Json file and converts into python data structure (dict or list, depending on JSON)
    jData = json.loads(myResponse.content)

    print("The response contains {0} properties".format(len(jData)))
    print("\n")
    for key in jData:
        print key + " : " + jData[key]
else:
  # If response code is not ok (200), print the resulting http error code with description
    myResponse.raise_for_status()

After closing and reopening VS, this should resolve.

@alvas has a good answer. But again it depends on the nature of the task, for example in your application you want to consider all conjunction e.g. and, or, but, if, while and all determiner e.g. the, a, some, most, every, no as stop words considering all others parts of speech as legitimate, then you might want to look into this solution which use Part-of-Speech Tagset to discard words, Check table 5.1:

import nltk

STOP_TYPES = ['DET', 'CNJ']

text = "some data here "
tokens = nltk.pos_tag(nltk.word_tokenize(text))
good_words = [w for w, wtype in tokens if wtype not in STOP_TYPES]

There is a good explanation of why it is costly to use + for concatenating a large number of strings here

Plus operator is perfectly fine solution to concatenate two Python strings. But if you keep adding more than two strings (n > 25) , you might want to think something else.

''.join([a, b, c]) trick is a performance optimization.

SQL Server Express editions are limited in some ways - one way is that they don't have the SQL Agent that allows you to schedule jobs.

There are a few third-party extensions that provide that capability - check out e.g.:

• Express Agent for SQL Server Express: Jobs, Jobs, Jobs and Mail (latest update is from 2005, it isn't maintained anymore).
• SQL Scheduler

NodeJS Solution:

In Nodejs you can get it via promises...

If you write this code, you can be sure that the page is fully loaded when you get to the then...

driver.get('www.sidanmor.com').then(()=> {
    // here the page is fully loaded!!!
    // do your stuff...
}).catch(console.log.bind(console));

If you write this code, you will navigate, and selenium will wait 3 seconds...

driver.get('www.sidanmor.com');
driver.sleep(3000);
// you can't be sure that the page is fully loaded!!!
// do your stuff... hope it will be OK...

From Selenium documentation:

this.get( url ) ? Thenable

Schedules a command to navigate to the given URL.

Returns a promise that will be resolved when the document has finished loading.

Selenium Documentation (Nodejs)

If you are working in ROOT, you do not even have to write #include<iostream> and using namespace std; simply start from int filename().

This will solve the issue.

Try this:

reverse_string(NULL);
reverse_string("");

here's another alternative using vector::assign:

theVector.assign(theSet.begin(), theSet.end());

event.target returns the DOM element, so you can retrieve any property/ attribute that has a value; so, to answer your question more specifically, you will always be able to retrieve nodeName, and you can retrieve href and id, provided the element has a href and id defined; otherwise undefined will be returned.

However, inside an event handler, you can use this, which is set to the DOM element as well; much easier.

$('foo').bind('click', function () {
    // inside here, `this` will refer to the foo that was clicked
});

Simple tabulation of the output:

a = 0.3333333
b = 200/3
print("variable a    variable b")
print("%10.2f    %10.2f" % (a, b))

output:

variable a    variable b
      0.33         66.67

%10.2f: 10 is the minimum length and 2 is the number of decimal places.

FYI, I am using Windows 7 and had to restart Windows in order for the new JAVA_HOME setting to take effect.

In case of changing all the keys at once. Here I am stemming the keys.

a = {'making' : 1, 'jumping' : 2, 'climbing' : 1, 'running' : 2}
b = {ps.stem(w) : a[w] for w in a.keys()}
print(b)
>>> {'climb': 1, 'jump': 2, 'make': 1, 'run': 2} #output

What you'll see sometimes is the following:

class Abstract1( object ):
    """Some description that tells you it's abstract,
    often listing the methods you're expected to supply."""
    def aMethod( self ):
        raise NotImplementedError( "Should have implemented this" )

Because Python doesn't have (and doesn't need) a formal Interface contract, the Java-style distinction between abstraction and interface doesn't exist. If someone goes through the effort to define a formal interface, it will also be an abstract class. The only differences would be in the stated intent in the docstring.

And the difference between abstract and interface is a hairsplitting thing when you have duck typing.

Java uses interfaces because it doesn't have multiple inheritance.

Because Python has multiple inheritance, you may also see something like this

class SomeAbstraction( object ):
    pass # lots of stuff - but missing something

class Mixin1( object ):
    def something( self ):
        pass # one implementation

class Mixin2( object ):
    def something( self ):
        pass # another

class Concrete1( SomeAbstraction, Mixin1 ):
    pass

class Concrete2( SomeAbstraction, Mixin2 ):
    pass

This uses a kind of abstract superclass with mixins to create concrete subclasses that are disjoint.

table { 
  border-spacing: 10px; 
} 

This worked for me once I removed

border-collapse: separate;

from my table tag.

In C++ the requirements imposed on default arguments with regard to their location in parameter list are as follows:

1. Default argument for a given parameter has to be specified no more than once. Specifying it more than once (even with the same default value) is illegal.

2. Parameters with default arguments have to form a contiguous group at the end of the parameter list.

Now, keeping that in mind, in C++ you are allowed to "grow" the set of parameters that have default arguments from one declaration of the function to the next, as long as the above requirements are continuously satisfied.

For example, you can declare a function with no default arguments

void foo(int a, int b);

In order to call that function after such declaration you'll have to specify both arguments explicitly.

Later (further down) in the same translation unit, you can re-declare it again, but this time with one default argument

void foo(int a, int b = 5);

and from this point on you can call it with just one explicit argument.

Further down you can re-declare it yet again adding one more default argument

void foo(int a = 1, int b);

and from this point on you can call it with no explicit arguments.

The full example might look as follows

void foo(int a, int b);

int main()
{
  foo(2, 3);

  void foo(int a, int b = 5); // redeclare
  foo(8); // OK, calls `foo(8, 5)`

  void foo(int a = 1, int b); // redeclare again
  foo(); // OK, calls `foo(1, 5)`
}

void foo(int a, int b)
{
  // ...
}

As for the code in your question, both variants are perfectly valid, but they mean different things. The first variant declares a default argument for the second parameter right away. The second variant initially declares your function with no default arguments and then adds one for the second parameter.

The net effect of both of your declarations (i.e. the way it is seen by the code that follows the second declaration) is exactly the same: the function has default argument for its second parameter. However, if you manage to squeeze some code between the first and the second declarations, these two variants will behave differently. In the second variant the function has no default arguments between the declarations, so you'll have to specify both arguments explicitly.

While others have pointed out it is not possible to override constructors syntactically, I would like to also point out, it would be conceptually bad to do so. Say the superclass is a dog object, and the subclass is a Husky object. The dog object has properties such as "4 legs", "sharp nose", if "override" means erasing dog and replacing it with Husky then Husky would be missing these properties and be a broken object. Husky never had those properties and simply inherited them from dog. On the other hand, if you intend to give Husky everything that dog has, then conceptually you could "override" dog with Husky, but there would be no point in creating a class that is the same as dog, it's not practically an inherited class but a complete replacement.

An update to i00g's and Thomas' answers, this time for VS2012 (some names have changed). After copying x86 settings over into an x64 target with the configuration manager, you'll have the problem for the same reason as was the case earlier (lib targets aren't correct in the x64 config). Open your .vcxproj (text editor) and replace MachineX86 with MachineX64 where appropriate. (I still haven't found where this is on the property sheets....) This only seems to be necessary with static libs.

For using FusedLocationProviderClient with Google Play Services 11 and higher:

see here: How to get current Location in GoogleMap using FusedLocationProviderClient

For using (now deprecated) FusedLocationProviderApi:

If your project uses Google Play Services 10 or lower, using the FusedLocationProviderApi is the optimal choice.

The FusedLocationProviderApi offers less battery drain than the old open source LocationManager API. Also, if you're already using Google Play Services for Google Maps, there's no reason not to use it.

Here is a full Activity class that places a Marker at the current location, and also moves the camera to the current position.

It also checks for the Location permission at runtime for Android 6 and later (Marshmallow, Nougat, Oreo). In order to properly handle the Location permission runtime check that is necessary on Android M/Android 6 and later, you need to ensure that the user has granted your app the Location permission before calling mGoogleMap.setMyLocationEnabled(true) and also before requesting location updates.

Result:

Show permission explanation if needed using an AlertDialog (this happens if the user denies a permission request, or grants the permission and then later revokes it in the settings):

Prompt the user for Location permission by calling ActivityCompat.requestPermissions():

Move camera to current location and place Marker when the Location permission is granted:

I think these are two really different cases. In the first case memory is allocated and initialized in compile-time. In the second - in runtime.

As indicated here https://stackoverflow.com/a/1632004/330867, you can implement it by "filtering" what is originating the exit of this page.

As mentionned in the comments, here's a new version of the code in the other question, which also include the ajax request you make in your question :

var canExit = true;

// For every function that will call an ajax query, you need to set the var "canExit" to false, then set it to false once the ajax is finished.

function checkCart() {
  canExit = false;
  $.ajax({
    url : 'index.php?route=module/cart/check',
    type : 'POST',
    dataType : 'json',
    success : function (result) {
       if (result) {
        canExit = true;
       }
    }
  })
}

$(document).on('click', 'a', function() {canExit = true;}); // can exit if it's a link
$(window).on('beforeunload', function() {
    if (canExit) return null; // null will allow exit without a question
    // Else, just return the message you want to display
    return "Do you really want to close?";
});

Important: You shouldn't have a global variable defined (here canExit), this is here for simpler version.

Note that you can't override completely the confirm message (at least in chrome). The message you return will only be prepended to the one given by Chrome. Here's the reason : How can I override the OnBeforeUnload dialog and replace it with my own?

The event must be cancelable. Adding an if statement solves this issue.

if (e.cancelable) {
   e.preventDefault();
}

In your code you should put it here:

if (this.isSwipe(swipeThreshold) && e.cancelable) {
   e.preventDefault();
   e.stopPropagation();
   swiping = true;
}

You Can Use This One

="Line 1" & "<br>" & "Line 2"

This should work:

SELECT field,CONVERT(SUBSTRING_INDEX(field,'-',-1),UNSIGNED INTEGER) AS num
FROM table
ORDER BY num;

In my case it was solved just passing proxy to connection. Thanks to @Andreas Panagiotidis.

Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("<YOUR.HOST>", 80)));
HttpsURLConnection con = (HttpsURLConnection) url.openConnection(proxy);

You can keep <button type="submit">, but must remove the attribute action="" of <form>.

A modification to GUS's example:

$(document).ready(function() {
    var tmpImg = new Image() ;
    tmpImg.onload = function() {
        // Run onload code.
    } ;

tmpImg.src = $('#img').attr('src');
})

Set the source before and after the onload.

you can bind to multiple events by separating them with a space:

$(":input").on("keyup change", function(e) {
    // do stuff!
})

docs here.

hope that helps. cheers!

The only thing can work for me is:

$('select2element').val(null).trigger("change")

I'm using version 4.0.3

Reference

According to Select2 Documentation

You can just add these code in AppServiceProvider class boot method.

Blade::extend(function($value, $compiler){
        $value = preg_replace('/(\s*)@switch\((.*)\)(?=\s)/', '$1<?php switch($2):', $value);
        $value = preg_replace('/(\s*)@endswitch(?=\s)/', '$1endswitch; ?>', $value);
        $value = preg_replace('/(\s*)@case\((.*)\)(?=\s)/', '$1case $2: ?>', $value);
        $value = preg_replace('/(?<=\s)@default(?=\s)/', 'default: ?>', $value);
        $value = preg_replace('/(?<=\s)@breakswitch(?=\s)/', '<?php break;', $value);
        return $value;
    });

then you can use as:

@switch( $item )
    @case( condition_1 )
        // do something
    @breakswitch
    @case( condition_2 )
        // do something else
    @breakswitch
    @default
        // do default behaviour
    @breakswitch
@endswitch

That is not always true; it only works in Windows.
For interacting with terminal in putty, Linux shell,... it will be used for returning the cursor to the beginning of line. following picture shows the usage of that:

Without '\r':

Data comes without '\r' to the putty terminal, it has just '\n'.
it means that data will be printed just in next line.

With '\r':

Data comes with '\r', i.e. string ends with '\r\n'. So the cursor in putty terminal not only will go to the next line but also at the beginning of line

Just use special `

var lyrics = 'Never gonna give you up';
var html = `<div>${lyrics}</div>`;

You can see more examples here.

I ran

docker info | grep Name: | xargs | cut -d' ' -f2

inside my container.

If you wrap one stream into another, you don't close intermediate streams, and very important: You don't close them before finishing using the outer streams. Because you would close the outer stream too.

mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;

These are deprecated use the following..

 // Connects to your Database
            $link = mysqli_connect("localhost", "root", "", "");

and to insert data use the following

 $sql = "INSERT INTO  Table-Name (Column-Name)
VALUES ('$filename')" ;

the secure way is encrypt your sensitive data by AES and the encryption key is derivation by password-based key derivation function (PBE), the master password used to encrypt/decrypt the encrypt key for AES.

master password -> secure key-> encrypt data by the key

You can use pbkdf2

from PBKDF2 import PBKDF2
from Crypto.Cipher import AES
import os
salt = os.urandom(8)    # 64-bit salt
key = PBKDF2("This passphrase is a secret.", salt).read(32) # 256-bit key
iv = os.urandom(16)     # 128-bit IV
cipher = AES.new(key, AES.MODE_CBC, iv)

make sure to store the salt/iv/passphrase , and decrypt using same salt/iv/passphase

Weblogic used similar approach to protect passwords in config files

I guess this is essentially putting it in a string, but this avoids the rounding error:

import decimal

def display(x):
    digits = 15
    temp = str(decimal.Decimal(str(x) + '0' * digits))
    return temp[:temp.find('.') + digits + 1]

There is one more way to use Java

import java.io._

def printToFile(f: java.io.File)(op: java.io.PrintWriter => Unit) 
  {
     val p = new java.io.PrintWriter(f);  
     try { op(p) } 
     finally { p.close() }
  } 

printToFile(new File("C:/TEMP/df.csv")) { p => df.collect().foreach(p.println)}

If you come from a class-based, statically typed object-oriented language (like Java, C++ or C#) I assume that you are trying to create a variable or method associated to a "type" but not to an instance.

An example using a "classical" approach, with constructor functions maybe could help you to catch the concepts of basic OO JavaScript:

function MyClass () { // constructor function
  var privateVariable = "foo";  // Private variable 

  this.publicVariable = "bar";  // Public variable 

  this.privilegedMethod = function () {  // Public Method
    alert(privateVariable);
  };
}

// Instance method will be available to all instances but only load once in memory 
MyClass.prototype.publicMethod = function () {    
  alert(this.publicVariable);
};

// Static variable shared by all instances
MyClass.staticProperty = "baz";

var myInstance = new MyClass();

staticProperty is defined in the MyClass object (which is a function) and has nothing to do with its created instances, JavaScript treats functions as first-class objects, so being an object, you can assign properties to a function.

UPDATE: ES6 introduced the ability to declare classes through the class keyword. It is syntax sugar over the existing prototype-based inheritance.

The static keyword allows you to easily define static properties or methods in a class.

Let's see the above example implemented with ES6 classes:

class MyClass {_x000D_
  // class constructor, equivalent to_x000D_
  // the function body of a constructor_x000D_
  constructor() {_x000D_
    const privateVariable = 'private value'; // Private variable at the constructor scope_x000D_
    this.publicVariable = 'public value'; // Public property_x000D_
_x000D_
    this.privilegedMethod = function() {_x000D_
      // Public Method with access to the constructor scope variables_x000D_
      console.log(privateVariable);_x000D_
    };_x000D_
  }_x000D_
_x000D_
  // Prototype methods:_x000D_
  publicMethod() {_x000D_
    console.log(this.publicVariable);_x000D_
  }_x000D_
_x000D_
  // Static properties shared by all instances_x000D_
  static staticProperty = 'static value';_x000D_
_x000D_
  static staticMethod() {_x000D_
    console.log(this.staticProperty);_x000D_
  }_x000D_
}_x000D_
_x000D_
// We can add properties to the class prototype_x000D_
MyClass.prototype.additionalMethod = function() {_x000D_
  console.log(this.publicVariable);_x000D_
};_x000D_
_x000D_
var myInstance = new MyClass();_x000D_
myInstance.publicMethod();       // "public value"_x000D_
myInstance.additionalMethod(); // "public value"_x000D_
myInstance.privilegedMethod(); // "private value"_x000D_
MyClass.staticMethod();             // "static value"

I had an application that I needed to convert from a JPA entity to DTO, and I thought about it and finally came up using org.springframework.beans.BeanUtils.copyProperties for copying simple properties and also extending and using org.springframework.binding.convert.service.DefaultConversionService for converting complex properties.

In detail my service was something like this:

@Service("seedingConverterService")
public class SeedingConverterService extends DefaultConversionService implements ISeedingConverterService  {
    @PostConstruct
    public void init(){
        Converter<Feature,FeatureDTO> featureConverter = new Converter<Feature, FeatureDTO>() {

            @Override
            public FeatureDTO convert(Feature f) {
                FeatureDTO dto = new FeatureDTO();
                //BeanUtils.copyProperties(f, dto,"configurationModel");
                BeanUtils.copyProperties(f, dto);
                dto.setConfigurationModelId(f.getConfigurationModel()==null?null:f.getConfigurationModel().getId());
                return dto;
            }
        };

        Converter<ConfigurationModel,ConfigurationModelDTO> configurationModelConverter = new Converter<ConfigurationModel,ConfigurationModelDTO>() {
            @Override
            public ConfigurationModelDTO convert(ConfigurationModel c) {
                ConfigurationModelDTO dto = new ConfigurationModelDTO();
                //BeanUtils.copyProperties(c, dto, "features");
                BeanUtils.copyProperties(c, dto);
                dto.setAlgorithmId(c.getAlgorithm()==null?null:c.getAlgorithm().getId());
                List<FeatureDTO> l = c.getFeatures().stream().map(f->featureConverter.convert(f)).collect(Collectors.toList());
                dto.setFeatures(l);
                return dto;

-a and -o are the older and/or operators for the test command. && and || are and/or operators for the shell. So (assuming an old shell) in your first case,

[ "$1" = 'yes' ] && [ -r $2.txt ]

The shell is evaluating the and condition. In your second case,

[ "$1" = 'yes' -a $2 -lt 3 ]

The test command (or builtin test) is evaluating the and condition.

Of course in all modern or semi-modern shells, the test command is built in to the shell, so there really isn't any or much difference. In modern shells, the if statement can be written:

[[ $1 == yes && -r $2.txt ]]

Which is more similar to modern programming languages and thus is more readable.

Check out the below library in git :

RuntimePermission

Implementation :

        allprojects {
            repositories {
                ...
                maven { url 'https://jitpack.io' }
            }
        }
        
        dependencies {

A generic script to run a sed expression on a list of files (combines the sed solution with the rename solution):

#!/bin/sh

e=$1
shift

for f in $*; do
    fNew=$(echo "$f" | sed "$e")
    mv "$f" "$fNew";
done

Invoke by passing the script a sed expression, and then any list of files, just like a version of rename:

script.sh 's/^fgh/jkl/' fgh*

$Group is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string").

Change $Group.StartsWith("S_G_") to $Group.samaccountname.StartsWith("S_G_").

To detach from the container you simply hold Ctrl and press P + Q.

To attach to a running container you use:

$ docker container attach "container_name"

5 workarounds:

The limit was raised in 5.7.7 (MariaDB 10.2.2?). And it can be increased with some work in 5.6 (10.1).

If you are hitting the limit because of trying to use CHARACTER SET utf8mb4. Then do one of the following (each has a drawback) to avoid the error:

?  Upgrade to 5.7.7 for 3072 byte limit -- your cloud may not provide this;
?  Change 255 to 191 on the VARCHAR -- you lose any values longer than 191 characters (unlikely?);
?  ALTER .. CONVERT TO utf8 -- you lose Emoji and some of Chinese;
?  Use a "prefix" index -- you lose some of the performance benefits.
?  Or... Stay with older version but perform 4 steps to raise the limit to 3072 bytes:

SET GLOBAL innodb_file_format=Barracuda;
SET GLOBAL innodb_file_per_table=1;
SET GLOBAL innodb_large_prefix=1;
logout & login (to get the global values);
ALTER TABLE tbl ROW_FORMAT=DYNAMIC;  -- (or COMPRESSED)

I found a way to use sc.

sc config binPath= "\"c:\path with spaces in it\service_executable.exe\" "

In other words, use \ to escape any "'s you want to survive the transit into the registry.

I think the problem is in your JOIN condition.

SELECT user.user_fname,
       user.user_lname,
       parent.user_fname,
       parent.user_lname
FROM users AS user
JOIN users AS parent 
  ON parent.user_id = user.user_parent_id
WHERE user.user_id = $_GET[id]

Edit: You should probably use LEFT JOIN if there are users with no parents.

I use a list with no bullets to give the "tabbed" appearance. (It's what I sometimes do when using MS Word)

In the CSS file:

.tab {
    margin-top: 0px;
    margin-bottom: 0px;
    list-style-type: none;
}

And in the HTML file use unordered lists:

This is normal text
<ul class="tab">
    <li>This is indented text</li>
</ul>

The beauty of this solution is that you can make further indentations using nested lists.

A noob here talking, so if there are any errors, please comment.

All user installed apks are located in /data/app/, but you can only access this if you are rooted(afaik, you can try without root and if it doesn't work, rooting isn't hard. I suggest you search xda-developers for rooting instructions)

Use Root explorer or ES File Explorer to access /data/app/ (you have to keep going "up" until you reach the root directory /, kind of like C: in windows, before you can see the data directory(folder)). In ES file explorer you must also tick a checkbox in settings to allow going up to the root directory.

When you are in there you will see all your applications apks, though they might be named strangely. Just copy the wanted .apk and paste in the sd card, after that you can copy it to your computer and when you want to install it just open the .apk in a file manager (be sure to have install from unknown sources enabled in android settings). Even if you only want to send over bluetooth I would recommend copying it to the SD first.

PS Note that paid apps probably won't work being copied this way, since they usually check their licence online. PPS Installing an app this way may not link it with google play(you won't see it in my apps and it won't get updates).

You need Linq - System.Xml.Linq to be precise.

You can create XML using XElement from scratch - that should pretty much sort you out.

I had to exit XCode, delete DerivedData folder contents (~/Library/Developer/Xcode/DerivedData or /Library/Developer/Xcode/DerivedData) and exit simulator to make this work.

The two are not exactly the same. I couldn't remember the exact differences, but they are outlined very well in What's quicker and better to determine if an array key exists in PHP?.

The common consensus seems to be to use isset whenever possible, because it is a language construct and therefore faster. However, the differences should be outlined above.

It does this by default, you just need to look into the project's /dist folder.

Try the code below:

>>> a = 0.99334
>>> a = int((a * 100) + 0.5) / 100.0 # Adding 0.5 rounds it up
>>> print a
0.99

You are debugging two or more times. so the application may run more at a time. Then only this issue will occur. You should close all debugging applications using task-manager, Then debug again.

zip extension is missing, You can avoid this error by simple running below command, It will take version by default

sudo apt-get install php-zip

In case you need any specific version, You need to mention a specific version of your php, Suppose I need to install X version of php-zip then the command will be.

sudo apt-get install phpX-zip  

Replace X with your required version, In my case, it is X = 7.3

declare
  x number;
begin
  x := myfunc(myargs);
end;

Alternatively:

select myfunc(myargs) from dual;

try this one:

get into the bin folder on terminal, then write:

sudo ./mongod --dbpath <write_here_the_path_to_your_database>, click enter. (always do same thing).

then sudo ./mongo

I had a similar problem with height except my chart was inside a bootstrap modal popup, which I'm already controlling the size of with css. However, for some reason when the window was resized horizontally the height of the chart container would expand indefinitely. If you were to drag the window back and forth it would expand vertically indefinitely. I also don't like hard-coded height/width solutions.

So, if you're doing this in a modal, combine this solution with a window resize event.

// from link
$('#ChartModal').on('show.bs.modal', function() {
    $('.chart-container').css('visibility', 'hidden');
});

$('#ChartModal').on('shown.bs.modal.', function() {
    $('.chart-container').css('visibility', 'initial');
    $('#chartbox').highcharts().reflow()
    //added
    ratio = $('.chart-container').width() / $('.chart-container').height();
});

Where "ratio" becomes a height/width aspect ratio, that will you resize when the bootstrap modal resizes. This measurement is only taken when he modal is opened. I'm storing ratio as a global but that's probably not best practice.

$(window).on('resize', function() {
    //chart-container is only visible when the modal is visible.
    if ( $('.chart-container').is(':visible') ) {
        $('#chartbox').highcharts().setSize( 
            $('.chart-container').width(),
            ($('.chart-container').width() / ratio),
            doAnimation = true );
    }       
});

So with this, you can drag your screen to the side (resizing it) and your chart will maintain its aspect ratio.

Widescreen

vs smaller

(still fiddling around with vw units, so everything in the back is too small to read lol!)

I'll tryto answer this in a more general approach:

foreach is used to iterate over each element of a given set or list (anything implementing IEnumerable) in a predefined manner. You can't influence the exact order (other than skipping entries or canceling the whole loop), as that's determined by the container.

foreach (String line in document) { // iterate through all elements of "document" as String objects
    Console.Write(line); // print the line
}

for is just another way to write a loop that has code executed before entering the loop and once after every iteration. It's usually used to loop through code a given number of times. Contrary to foreach here you're able to influence the current position.

for (int i = 0, j = 0; i < 100 && j < 10; ++i) { // set i and j to 0, then loop as long as i is less than 100 or j is less than 10 and increase i after each iteration
    if (i % 8 == 0) { // skip all numbers that can be divided by 8 and count them in j
        ++j
        continue;
    }
    Console.Write(i);
}
Console.Write(j);

If possible and applicable, always use foreach rather than for (assuming there's some array index). Depending on internal data organisation, foreach can be a lot faster than using for with an index (esp. when using linked lists).

You may want to consider using a different type of loop where that logic is applicable, because it is the most obvious answer.

perhaps a:

i=2
while i < n:
    if something:
       do something
       i += 1
    else: 
       do something else  
       i = 2 #restart the loop  

Solution #1: Python builtin

use SequenceMatcher from difflib

pros: native python library, no need extra package.
cons: too limited, there are so many other good algorithms for string similarity out there.

>>> from difflib import SequenceMatcher
>>> s = SequenceMatcher(None, "abcd", "bcde")
>>> s.ratio()
0.75

Solution #2: jellyfish library

its a very good library with good coverage and few issues. it supports:
- Levenshtein Distance
- Damerau-Levenshtein Distance
- Jaro Distance
- Jaro-Winkler Distance
- Match Rating Approach Comparison
- Hamming Distance

pros: easy to use, gamut of supported algorithms, tested.
cons: not native library.

example:

>>> import jellyfish
>>> jellyfish.levenshtein_distance(u'jellyfish', u'smellyfish')
2
>>> jellyfish.jaro_distance(u'jellyfish', u'smellyfish')
0.89629629629629637
>>> jellyfish.damerau_levenshtein_distance(u'jellyfish', u'jellyfihs')
1

It's an HtmlGenericControl so not sure what the recommended way to do this is, so you could also do:

testSpace.Attributes.Add("style", "text-align: center;");

or

testSpace.Attributes.Add("class", "centerIt");

or

testSpace.Attributes["style"] = "text-align: center;";

or

testSpace.Attributes["class"] = "centerIt";

In working with a similar problem I created the following function after combining a lot of resources I ran into on the web, and adding my own cookie handling. Hopefully this is useful to someone else.

      function get_web_page( $url, $cookiesIn = '' ){
        $options = array(
            CURLOPT_RETURNTRANSFER => true,     // return web page
            CURLOPT_HEADER         => true,     //return headers in addition to content
            CURLOPT_FOLLOWLOCATION => true,     // follow redirects
            CURLOPT_ENCODING       => "",       // handle all encodings
            CURLOPT_AUTOREFERER    => true,     // set referer on redirect
            CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
            CURLOPT_TIMEOUT        => 120,      // timeout on response
            CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
            CURLINFO_HEADER_OUT    => true,
            CURLOPT_SSL_VERIFYPEER => true,     // Validate SSL Certificates
            CURLOPT_HTTP_VERSION   => CURL_HTTP_VERSION_1_1,
            CURLOPT_COOKIE         => $cookiesIn
        );

        $ch      = curl_init( $url );
        curl_setopt_array( $ch, $options );
        $rough_content = curl_exec( $ch );
        $err     = curl_errno( $ch );
        $errmsg  = curl_error( $ch );
        $header  = curl_getinfo( $ch );
        curl_close( $ch );

        $header_content = substr($rough_content, 0, $header['header_size']);
        $body_content = trim(str_replace($header_content, '', $rough_content));
        $pattern = "#Set-Cookie:\\s+(?<cookie>[^=]+=[^;]+)#m"; 
        preg_match_all($pattern, $header_content, $matches); 
        $cookiesOut = implode("; ", $matches['cookie']);

        $header['errno']   = $err;
        $header['errmsg']  = $errmsg;
        $header['headers']  = $header_content;
        $header['content'] = $body_content;
        $header['cookies'] = $cookiesOut;
    return $header;
}

public static void main(String[] args) {

    LinkedList list = new LinkedList();
    list.insertFront(1);
    list.insertFront(2);
    list.insertFront(3);
    System.out.println(list.toString());
}

String toString() {
            String result = "";
            LinkedListNode current = head;
            while(current.getNext() != null){
                result += current.getData();
                if(current.getNext() != null){
                     result += ", ";
                }
                current = current.getNext();
            }
            return "List: " + result;
}

You can modify with the following

<li><a href="./Index" class="elements"><span>Clients</span></a></li>

The extra dot means you are in the same controller. If you want change the controller to a different controller then you can write this

<li><a href="../newController/Index" class="elements"><span>Clients</span></a></li>

You'd treat one of the files as a python module and make the other one import it (just as you import standard python modules). The latter can then refer to objects (including classes and functions) defined in the imported module. The module can also run whatever initialization code it needs. See http://docs.python.org/tutorial/modules.html

As for your problem, currently you will have to depend on XHR or websockets for this.

Currently no popular browser has implemented any such raw sockets api for javascript that lets you create and access raw sockets, but a draft for the implementation of raw sockets api in JavaScript is under-way. Have a look at these links:
http://www.w3.org/TR/raw-sockets/
https://developer.mozilla.org/en-US/docs/Web/API/TCPSocket

Chrome now has support for raw TCP and UDP sockets in its ‘experimental’ APIs. These features are only available for extensions and, although documented, are hidden for the moment. Having said that, some developers are already creating interesting projects using it, such as this IRC client.

To access this API, you’ll need to enable the experimental flag in your extension’s manifest. Using sockets is pretty straightforward, for example:

chrome.experimental.socket.create('tcp', '127.0.0.1', 8080, function(socketInfo) {
  chrome.experimental.socket.connect(socketInfo.socketId, function (result) {
        chrome.experimental.socket.write(socketInfo.socketId, "Hello, world!");         
    });
});

The query() function returns an object, you'll want fetch a record from what's returned from that function. Look at the examples on this page to learn how to print data from mysql

$(`input[id="${this.name}"]`).hide();

As you're using an ID, this would perform better

$(`#${this.name}`).hide();

I highly recommend being more specific with your approach to hiding elements via button clicks. I would opt for using data-attributes instead. For example

<input id="bx" type="text">
<button type="button" data-target="#bx" data-method="hide">Hide some input</button>

Then, in your JavaScript

// using event delegation so no need to wrap it in .ready()
$(document).on('click', 'button[data-target]', function() {
    var $this = $(this),
        target = $($this.data('target')),
        method = $this.data('method') || 'hide';
    target[method]();
});

Now you can completely control which element you're targeting and what happens to it via the HTML. For example, you could use data-target=".some-class" and data-method="fadeOut" to fade-out a collection of elements.

To expand on @loganfsmyth's answer:

The only truly private data in JavaScript is still scoped variables. You can't have private properties in the sense of properties accessed internally the same way as public properties, but you can use scoped variables to store private data.

Scoped variables

The approach here is to use the scope of the constructor function, which is private, to store private data. For methods to have access to this private data they must be created within the constructor as well, meaning you're recreating them with every instance. This is a performance and memory penalty, but some believe the penalty is acceptable. The penalty can be avoided for methods that do not need access to private data by adding them to the prototype as usual.

Example:

function Person(name) {
  let age = 20; // this is private
  this.name = name; // this is public

  this.greet = function () {
    // here we can access both name and age
    console.log(`name: ${this.name}, age: ${age}`);
  };
}

let joe = new Person('Joe');
joe.greet();

// here we can access name but not age

Scoped WeakMap

A WeakMap can be used to avoid the previous approach's performance and memory penalty. WeakMaps associate data with Objects (here, instances) in such a way that it can only be accessed using that WeakMap. So, we use the scoped variables method to create a private WeakMap, then use that WeakMap to retrieve private data associated with this. This is faster than the scoped variables method because all your instances can share a single WeakMap, so you don't need to recreate methods just to make them access their own WeakMaps.

Example:

let Person = (function () {
  let privateProps = new WeakMap();

  class Person {
    constructor(name) {
      this.name = name; // this is public
      privateProps.set(this, {age: 20}); // this is private
    }

    greet() {
      // Here we can access both name and age
      console.log(`name: ${this.name}, age: ${privateProps.get(this).age}`);
    }
  }

  return Person;
})();

let joe = new Person('Joe');
joe.greet();

// here we can access joe's name but not age

This example uses an Object to use one WeakMap for multiple private properties; you could also use multiple WeakMaps and use them like age.set(this, 20), or write a small wrapper and use it another way, like privateProps.set(this, 'age', 0).

The privacy of this approach could theoretically be breached by tampering with the global WeakMap object. That said, all JavaScript can be broken by mangled globals. Our code is already built on the assumption that this isn't happening.

(This method could also be done with Map, but WeakMap is better because Map will create memory leaks unless you're very careful, and for this purpose the two aren't otherwise different.)

Half-Answer: Scoped Symbols

A Symbol is a type of primitive value that can serve as a property name. You can use the scoped variable method to create a private Symbol, then store private data at this[mySymbol].

The privacy of this method can be breached using Object.getOwnPropertySymbols, but is somewhat awkward to do.

Example:

let Person = (function () {
  let ageKey = Symbol();

  class Person {
    constructor(name) {
      this.name = name; // this is public
      this[ageKey] = 20; // this is intended to be private
    }

    greet() {
      // Here we can access both name and age
      console.log(`name: ${this.name}, age: ${this[ageKey]}`);
    }
  }

  return Person;
})();

let joe = new Person('Joe');
joe.greet();

// Here we can access joe's name and, with a little effort, age. ageKey is
// not in scope, but we can obtain it by listing all Symbol properties on
// joe with `Object.getOwnPropertySymbols(joe)`.

Half-Answer: Underscores

The old default, just use a public property with an underscore prefix. Though not a private property in any way, this convention is prevalent enough that it does a good job communicating that readers should treat the property as private, which often gets the job done. In exchange for this lapse, we get an approach that's easier to read, easier to type, and faster.

Example:

class Person {
  constructor(name) {
    this.name = name; // this is public
    this._age = 20; // this is intended to be private
  }

  greet() {
    // Here we can access both name and age
    console.log(`name: ${this.name}, age: ${this._age}`);
  }
}

let joe = new Person('Joe');
joe.greet();

// Here we can access both joe's name and age. But we know we aren't
// supposed to access his age, which just might stop us.

Conclusion

As of ES2017, there's still no perfect way to do private properties. Various approaches have pros and cons. Scoped variables are truly private; scoped WeakMaps are very private and more practical than scoped variables; scoped Symbols are reasonably private and reasonably practical; underscores are often private enough and very practical.

Excel

Recently I discovered an explicit mimetype for Excel application/vnd.ms-excel. It was registered with IANA in '96. Note the concerns raised about being at the mercy of the sender and having your machine violated.

Media Type: application/vnd.ms-excel

Name Microsoft Excel (tm)

Required parameters: None

Optional parameters: name

Encoding considerations: base64 preferred

Security considerations: As with most application types this data is intended for interpretation by a program that understands the data on the recipient's system. Recipients need to understand that they are at the "mercy" of the sender, when receiving this type of data, since data will be executed on their system, and the security of their machines can be violated.

OID { org-id ms-files(4) ms-excel (3) }

Object type spreadsheet

Comments This Media Type/OID is used to identify Microsoft Excel generically (i.e., independent of version, subtype, or platform format).

The sample config you provided is actually valid YAML. In fact, YAML meets all of your demands, is implemented in a large number of languages, and is extremely human friendly. I would highly recommend you use it. The PyYAML project provides a nice python module, that implements YAML.

To use the yaml module is extremely simple:

import yaml
config = yaml.safe_load(open("path/to/config.yml"))

Exit [construct], and intelisense will tell you which one(s) are valid in a particular place.

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.

The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.

-Xmssize Specifies the initial heap size.

-Xmxsize Specifies the maximum heap size.

-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.

Sizes are expressed in bytes. Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, g or G to indicate gigabytes.

I've had trouble with git revert in the past (mainly because I'm not quite certain how it works.) I've had trouble reverting because of merge problems..

My simple solution is this.

Step 1.

 git clone <your repos URL> .

your project in another folder, then:

Step 2.

git reset --hard <the commit you wanna go to>

then Step 3.

in your latest (and main) project dir (the one that has the problematic last commit) paste the files of step 2

Step 4.

git commit -m "Fixing the previous messy commit"

I bet you are retrieving data in non-utf8 encoding: try to put mysql_query('SET CHARACTER SET utf8') before your SELECT query.

cbindX from the package gdata combines multiple columns of differing column and row lengths. Check out the page here:

http://hosho.ees.hokudai.ac.jp/~kubo/Rdoc/library/gdata/html/cbindX.html

It takes multiple comma separated matrices and data.frames as input :) You just need to

install.packages("gdata", dependencies=TRUE)

and then

library(gdata)
concat_data <- cbindX(df1, df2, df3) # or cbindX(matrix1, matrix2, matrix3, matrix4)

Here is a version that expects a pathlib.Path as input.

# Recusively copies the content of the directory src to the directory dst.
# If dst doesn't exist, it is created, together with all missing parent directories.
# If a file from src already exists in dst, the file in dst is overwritten.
# Files already existing in dst which don't exist in src are preserved.
# Symlinks inside src are copied as symlinks, they are not resolved before copying.
#
def copy_dir(src, dst):
    dst.mkdir(parents=True, exist_ok=True)
    for item in os.listdir(src):
        s = src / item
        d = dst / item
        if s.is_dir():
            copy_dir(s, d)
        else:
            shutil.copy2(str(s), str(d))

Note that this function requires Python 3.6, which is the first version of Python where os.listdir() supports path-like objects as input. If you need to support earlier versions of Python, you can replace listdir(src) by listdir(str(src)).

You can use Streams In Java 8 (this is exmaple of Set):

@Test
public void whenInitializeUnmodifiableSetWithDoubleBrace_containsElements() {
    Set<String> countries = Stream.of("India", "USSR", "USA")
      .collect(collectingAndThen(toSet(), Collections::unmodifiableSet));

    assertTrue(countries.contains("India"));
}

Another simple solution is to use map() as follows:

tensor_shape = map(int, my_tensor.shape)

This converts all the Dimension objects to int

My solution depends on three things thing:

1. keydown event
2. masking the field name
3. blanking the fields values on submit

First of all, we need to prevent autocomplete of both username and password, so, initially we will set two flags, i -> username and j -> passowrd with true value, so without any keydown to the fields both i and j will be true.

In may case the field masking is occured at the server side, by passing random string, it could be made easily made using client side too.

This is the code:

$(document).ready(function(){
   i= true; //username flag
   j= true; // password flag
   $("#username{{$rand}}").keydown(function(e){
          // {{$rand}} is server side value passed in blade view
          // keyboard buttons are clicked in the field
            i = false;       
    });
   $("#passowrd{{$rand}}").keydown(function(e){
          // {{$rand}} is server side value passed in blade view
          // keyboard buttons are clicked in the field
            j = false;       
    });
    // Now we will use change event,
   $("#username{{$rand}}").change(function(){
    if($(this).val() != ''){ //the field has value
        if(i){ // there is no keyboard buttons clicked over it
            $(this).val(''); // blank the field value
        }

    }
})
$("#password{{$rand}}").change(function(){
    if($(this).val() != ''){ // the same as username but using flag j
        if(j){
            $(this).val('');
        }

    }
})

   $("#sForm").submit(function(e){ // the id of my form
      $("#password-s").val($("#password{{$rand}}").val());
        $("#username-s").val($("#username{{$rand}}").val());
        // Here the server will deal with fields names `password` and `username` of the hidden fields
       $("#username{{$rand}}").val('');
        $("#password{{$rand}}").val(''); 

 })
})

Here are the HTML:

<form class="form-horizontal" autocomplete="off" role="form" id="sForm" method="POST" action="https://example.com/login">

                        <input type="hidden" name="password" id="password-s">
                        <input type="hidden" name="username" id="username-s">

                            <label for="usernameTDU3m4d3I5" class="col-md-3 control-label" style="white-space: nowrap">Username</label>

                                <input id="usernameTDU3m4d3I5" placeholder="Username" autocomplete="off" style="border-bottom-left-radius: 10px; border-top-right-radius: 10px; font-family: fixed; font-size: x-large;" type="text" class="form-control" name="usernameTDU3m4d3I5" value="" required="required" autofocus="">                                

                            <label for="passwordTDU3m4d3I5" class="col-md-3 control-label" style="white-space: nowrap">Password</label>
                                <input id="passwordTDU3m4d3I5" placeholder="Password" autocomplete="off" type="password" class="form-control" name="pa-TDU3m4d3I5" required="">


                                <button type="submit" class="btn btn-success">
                                    <i class="fox-login" style="text-shadow: 0px 1px 0px #000"></i><strong>Login</strong>&nbsp;&nbsp;
                                </button>

                                </form>

The above solution, indeed, will not eliminate or prevent the autocomplete of the username and password, but it make that autocomplete useless. i.e without hitting keyboard button on the field, the field value will be blank before submit, so the user will be asked to enter them.

Update

We can, also, use click event to prevent autocomplete from users list appeared under the field like the following:

 $("#username{{$rand}}").click(function(){

            $(this).val('');
            i = true;

})
$("#password{{$rand}}").click(function(){

            $(this).val('');
            j = true;

})

Limitations:

This solution may not work as expected in touch screen devices.

Final Update

I have done the following clean implementation like the following:

preventAutoComplete = true; // modifier to allow or disallow autocomplete
trackInputs = {password:"0", username:"0"}; //Password and username fields ids as object's property, and "0" as its their values
// Prevent autocomplete
    if(preventAutoComplete){
        $("input").change(function(e){ // Change event is fired as autocomplete occurred at the input field 
            trackId = $(this).attr('id'); //get the input field id to access the trackInputs object            
            if (trackInputs[trackId] == '0' || trackInputs[trackId] != $(this).val()){ //trackInputs property value not changed or the prperty value ever it it is not equals the input field value
                $(this).val(''); // empty the field
            }
        });
        $("input").keyup(function(e){
            trackId = $(this).attr('id');
            trackInputs[trackId] = $(this).val(); //Update trackInputs property with the value of the field with each keyup.
        });
    } 

Assume you were:

1. Reading a network file and got disconnected.
2. Reading a local file that was no longer available.
3. Using some stream to read data and some other process closed the stream.
4. Trying to read/write a file, but don't have permission.
5. Trying to write to a file, but disk space was no longer available.

There are many more examples, but these are the most common, in my experience.

Add

t1.Join();    // Wait until thread t1 finishes

after you start it, but that won't accomplish much as it's essentialy the same result as running on the main thread!

I can highly recommended reading Joe Albahari's Threading in C# free e-book, if you want to gain an understanding of threading in .NET.

Assuming that you are using the m2e plugin in Eclipse, you'll need to specify the source and target versions as 1.6 for maven-compiler-plugin. m2e uses these values to determine the project's Java compiler level. A snippet of the POM is shown below:

<build>
  <plugins>
    <plugin>
      <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.6</source>
          <target>1.6</target>
        </configuration>
    </plugin>
  </plugins>
</build>

Alternatively, you can specify the maven.compiler.source and maven.compiler.target properties with values of 1.6, that happen to be the equivalent:

<properties>
    <maven.compiler.target>1.6</maven.compiler.target>
    <maven.compiler.source>1.6</maven.compiler.source>
</properties>

SELECT
  GROUP_CONCAT(DISTINCT (category))
FROM (
  SELECT
    SUBSTRING_INDEX(SUBSTRING_INDEX(tableName.categories, ' ', numbers.n), ' ', -1) category
  FROM
    numbers INNER JOIN tableName
    ON LENGTH(tableName.categories)>=LENGTH(REPLACE(tableName.categories, ' ', ''))+numbers.n-1
  ) s;   

This will return distinct values like: test1,test2,test4,test3

I recently had the same problem and used the solution provided by Harry Joy. That solution only works with with zero-based enumaration though. I also wouldn't consider it save as it doesn't deal with indexes that are out of range.

The solution I ended up using might not be as simple but it's completely save and won't hurt the performance of your code even with big enums:

public enum Example {

    UNKNOWN(0, "unknown"), ENUM1(1, "enum1"), ENUM2(2, "enum2"), ENUM3(3, "enum3");

    private static HashMap<Integer, Example> enumById = new HashMap<>();
    static {
        Arrays.stream(values()).forEach(e -> enumById.put(e.getId(), e));
    }

    public static Example getById(int id) {
        return enumById.getOrDefault(id, UNKNOWN);
    }

    private int id;
    private String description;

    private Example(int id, String description) {
        this.id = id;
        this.description= description;
    }

    public String getDescription() {
        return description;
    }

    public int getId() {
        return id;
    }
}

If you are sure that you will never be out of range with your index and you don't want to use UNKNOWN like I did above you can of course also do:

public static Example getById(int id) {
        return enumById.get(id);
}

The JSONArray.length() returns the number of elements in the JSONObject contained in the Array. Not the size of the array itself.

TS has a JavaScript runtime

Typescript has a JavaScript runtime because it gets compiled to JS. This means JS objects which are built in as part of the language such as JSON, Object, and Math are also available in TS. Therefore we can just use the JSON.parse method to parse the JSON string.

Example:

const JSONStr = '{"name": "Bob", "error": false}'

// The JSON object is part of the runtime
const parsedObj = JSON.parse(JSONStr);

console.log(parsedObj);
// [LOG]: {
//   "name": "Bob",
//   "error": false
// } 

// The Object object is also part of the runtime so we can use it in TS
const objKeys = Object.keys(parsedObj);

console.log(objKeys);
// [LOG]: ["name", "error"] 

The only thing now is that parsedObj is type any which is generally a bad practice in TS. We can type the object if we are using type guards. Here is an example:

const JSONStr = '{"name": "Bob", "error": false}'
const parsedObj = JSON.parse(JSONStr);

interface nameErr {
  name: string;
  error: boolean;
}

function isNameErr(arg: any): arg is nameErr {
  if (typeof arg.name === 'string' && typeof arg.error === 'boolean') {
    return true;
  } else {
    return false;
  }
}

if (isNameErr(parsedObj)) {
  // Within this if statement parsedObj is type nameErr;
  parsedObj
}

Use your WorkSheet.Columns.NumberFormat, and set it to string "@", here is the sample:

Excel._Worksheet workSheet = (Excel._Worksheet)_Excel.Worksheets.Add();
//set columns format to text format
workSheet.Columns.NumberFormat = "@";

Note: this text format will apply for your hole excel sheet!

If you want a particular column to apply the text format, for example, the first column, you can do this:

workSheet.Columns[0].NumberFormat = "@";

or this will apply the specified range of woorkSheet to text format:

workSheet.get_Range("A1", "D1").NumberFormat = "@";

just use

=link_to "link", "javascript:function()"

Security dictates that pointers aren’t used in Java so hackers can’t break out of an application and into the operating system. No pointers means that something else----in this case, the JVM----has to take care of the allocating and freeing memory. Memory leaks should also become a thing of the past, or so the theory goes. Some applications written in C and C++ are notorious for leaking memory like a sieve because programmers don’t pay attention to freeing up unwanted memory at the appropriate time----not that anybody reading this would be guilty of such a sin. Garbage collection should also make programmers more productive, with less time spent on debugging memory problems.

There is a very fundamental difference between the two. In case of Singleton design pattern, only one instance of a class will be created per classLoader while that is not the case with Spring singleton as in the later one shared bean instance for the given id per IoC container is created.

For example, if I have a class with the name "SpringTest" and my XML file looks something like this :-

<bean id="test1" class="com.SpringTest" scope="singleton">
        --some properties here
</bean>    
<bean id="test2" class="com.SpringTest" scope="singleton">
        --some properties here   
</bean>

So now in the main class if you will check the reference of the above two it will return false as according to Spring documentation:-

When a bean is a singleton, only one shared instance of the bean will be managed, and all requests for beans with an id or ids matching that bean definition will result in that one specific bean instance being returned by the Spring container

So as in our case, the classes are the same but the id's that we have provided are different hence resulting in two different instances being created.

Deep copy literally performs a deep copy. It means, that if your class has some fields that are references, their values will be copied, not references themselves. If, for example you have two instances of a class, A & B with fields of reference type, and perform a deep copy, changing a value of that field in A won't affect a value in B. And vise-versa. Things are different with shallow copy, because only references are copied, therefore, changing this field in a copied object would affect the original object.

What type of a copy does a copy constructor does?

It is implementation - dependent. This means that there are no strict rules about that, you can implement it like a deep copy or shallow copy, however as far as i know it is a common practice to implement a deep copy in a copy constructor. A default copy constructor performs a shallow copy though.

As Kevin Haines points out, ints have the natural size suggested by the execution environment, which has to fit within INT_MIN and INT_MAX.

The C89 standard states that UINT_MAX should be at least 2^16-1, USHRT_MAX 2^16-1 and ULONG_MAX 2^32-1 . That makes a bit-count of at least 16 for short and int, and 32 for long. For char it states explicitly that it should have at least 8 bits (CHAR_BIT). C++ inherits those rules for the limits.h file, so in C++ we have the same fundamental requirements for those values. You should however not derive from that that int is at least 2 byte. Theoretically, char, int and long could all be 1 byte, in which case CHAR_BIT must be at least 32. Just remember that "byte" is always the size of a char, so if char is bigger, a byte is not only 8 bits any more.

If json object key/name contains dot......! like

var myJson = {"my.name":"vikas","my.age":27}

Than you can access like

myJson["my.name"]
myJson["my.age"]

Depending on the libc release it could be needed to set both SO_REUSEADDR and SO_REUSEPORT socket options as explained in socket(7) documentation :

   SO_REUSEPORT (since Linux 3.9)
          Permits multiple AF_INET or AF_INET6 sockets to be bound to an
          identical socket address.  This option must be set on each
          socket (including the first socket) prior to calling bind(2)
          on the socket.  To prevent port hijacking, all of the
          processes binding to the same address must have the same
          effective UID.  This option can be employed with both TCP and
          UDP sockets.

As this socket option appears with kernel 3.9 and raspberry use 3.12.x, it will be needed to set SO_REUSEPORT.

You can set theses two options before calling bind like this :

    int reuse = 1;
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, (const char*)&reuse, sizeof(reuse)) < 0)
        perror("setsockopt(SO_REUSEADDR) failed");

#ifdef SO_REUSEPORT
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEPORT, (const char*)&reuse, sizeof(reuse)) < 0) 
        perror("setsockopt(SO_REUSEPORT) failed");
#endif

Finally I found solution in Spring Docs:

To completely disable the use of file extensions, you must set both of the following:

 useSuffixPatternMatching(false), see PathMatchConfigurer

 favorPathExtension(false), see ContentNegotiationConfigurer

Adding this to my WebMvcConfigurerAdapter implementation solved the problem:

@Override
public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
    configurer.favorPathExtension(false);
}

@Override
public void configurePathMatch(PathMatchConfigurer matcher) {
    matcher.setUseSuffixPatternMatch(false);
}

Looks like one way to handle this in Rails 2.3 (since update_without_callbacks is gone, etc.), would be to use update_all, which is one of the methods that skips callbacks as per section 12 of the Rails Guide to validations and callbacks.

Also, note that if you are doing something in your after_ callback, that does a calculation based on many association (i.e. a has_many assoc, where you also do accepts_nested_attributes_for), you will need to reload the association, in case as part of the save, one of its members was deleted.

Write below function to get date in string, convert and return in string format.

getParsedDate(strDate){
    var strSplitDate = String(strDate).split(' ');
    var date = new Date(strSplitDate[0]);
    // alert(date);
    var dd = date.getDate();
    var mm = date.getMonth() + 1; //January is 0!

    var yyyy = date.getFullYear();
    if (dd < 10) {
        dd = '0' + dd;
    }
    if (mm < 10) {
        mm = '0' + mm;
    }
    date =  dd + "-" + mm + "-" + yyyy;
    return date.toString();
}

Print it where you required: Date : {this.getParsedDate(stringDate)}

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.

Use sudo pip3 install jupyter for installing jupyter for python3 and sudo pip install jupyter for installing jupyter notebook for python2. Then, you can call ipython kernel install command to enable both types of notebook to choose from in jupyter notebook.

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

Add the folders which you don't want to trigger servlet processing to the <static-files> section of your appengine-web.xml file.

I just did this and looks like things are starting to work ok. Here's my structure:

/

/pages/<.jsp files>

/css

I added "/pages/**" and "/css/**" to the <static-files> section and I can now forward to a .jsp file from inside a servlet doGet without causing an infinite loop.

You need to do the following:

public class CountryInfoResponse {

   @JsonProperty("geonames")
   private List<Country> countries; 

   //getter - setter
}

RestTemplate restTemplate = new RestTemplate();
List<Country> countries = restTemplate.getForObject("http://api.geonames.org/countryInfoJSON?username=volodiaL",CountryInfoResponse.class).getCountries();

It would be great if you could use some kind of annotation to allow you to skip levels, but it's not yet possible (see this and this)
