Synalyze It! allows to compare text or bytes in all encodings the ICU library offers. Using that feature you usually see immediately which code page makes sense for your data.

Great answer of Josh, all credit to him, I slightly modified it to this however:

MyDialog Xaml

    <StackPanel Margin="5,5,5,5">
        <TextBlock Name="TitleTextBox" Margin="0,0,0,10" />
        <TextBox Name="InputTextBox" Padding="3,3,3,3" />
        <Grid Margin="0,10,0,0">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <Button Name="BtnOk" Content="OK" Grid.Column="0" Margin="0,0,5,0" Padding="8" Click="BtnOk_Click" />
            <Button Name="BtnCancel" Content="Cancel" Grid.Column="1" Margin="5,0,0,0" Padding="8" Click="BtnCancel_Click" />
        </Grid>
    </StackPanel>

MyDialog Code Behind

    public MyDialog()
    {
        InitializeComponent();
    }

    public MyDialog(string title,string input)
    {
        InitializeComponent();
        TitleText = title;
        InputText = input;
    }

    public string TitleText
    {
        get { return TitleTextBox.Text; }
        set { TitleTextBox.Text = value; }
    }

    public string InputText
    {
        get { return InputTextBox.Text; }
        set { InputTextBox.Text = value; }
    }

    public bool Canceled { get; set; }

    private void BtnCancel_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Canceled = true;
        Close();
    }

    private void BtnOk_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Canceled = false;
        Close();
    }

And call it somewhere else

var dialog = new MyDialog("test", "hello");
dialog.Show();
dialog.Closing += (sender,e) =>
{
    var d = sender as MyDialog;
    if(!d.Canceled)
        MessageBox.Show(d.InputText);
}

cast it to a string or char[] and loop on it

public void setHoursWorked(){
    hoursWorked = hours;
}

You haven't defined hours inside that method. hours is not passed in as a parameter, it's not declared as a variable, and it's not being used as a class member, so you get that error.

It could be done in Bootstrap 4 using the responsive grid columns. One column for the sidebar and one for the main content.

Bootstrap 4 Sidebar switch to Top Navbar on mobile

<div class="container-fluid h-100">
    <div class="row h-100">
        <aside class="col-12 col-md-2 p-0 bg-dark">
            <nav class="navbar navbar-expand navbar-dark bg-dark flex-md-column flex-row align-items-start">
                <div class="collapse navbar-collapse">
                    <ul class="flex-md-column flex-row navbar-nav w-100 justify-content-between">
                        <li class="nav-item">
                            <a class="nav-link pl-0" href="#">Link</a>
                        </li>
                        ..
                    </ul>
                </div>
            </nav>
        </aside>
        <main class="col">
            ..
        </main>
    </div>
</div>

Alternate sidebar to top
Fixed sidebar to top

For the reverse (Top Navbar that becomes a Sidebar), can be done like this example

you can use

$('#elementID').css('background-color', '#C0C0C0');

Thanks to the answer of redsquare I added a method like this:

$.validator.addMethod(
  "regex",
  function(value, element, regexp) {
    var re = new RegExp(regexp);
    return this.optional(element) || re.test(value);
  },
  "Please check your input."
);

Now all you need to do to validate against any regex is this:

$("#Textbox").rules("add", { regex: "^[a-zA-Z'.\\s]{1,40}$" })

Additionally, it looks like there is a file called additional-methods.js that contains the method "pattern", which can be a RegExp when created using the method without quotes.

Edit

The pattern function is now the preferred way to do this, making the example:

$("#Textbox").rules("add", { pattern: "^[a-zA-Z'.\\s]{1,40}$" })

In my case I exported Drupal instance from server to localhost on XAMPP. It obviously did not do justice to the file and directory ownership and Apache was throwing the above error.

This is the ownership of files and directories initially:

To give read permissions to my files and execute permission to my directories I could do so that all users can read, write and execute:

sudo chmod 777 -R

but that would not be the ideal solution coz this would be migrated back to server and might end up with a security loophole.

A script is given in this blog: https://www.drupal.org/node/244924

#!/bin/bash

# Help menu
print_help() {

This script is used to fix permissions of a Drupal installation
you need to provide the following arguments:

  1) Path to your Drupal installation.
  2) Username of the user that you want to give files/directories ownership.
  3) HTTPD group name (defaults to www-data for Apache).

And need to invoke the command:

sudo bash /Applications/XAMPP/xamppfiles/htdocs/fix-permissions.sh --drupal_path=/Applications/XAMPP/xamppfiles/htdocs/rkmission --drupal_user=daemon --httpd_group=admin

In my case the user on which Apache is running is 'daemon'. You can identify the user by just running this php script in a php file through localhost:

<?php echo exec('whoami');?>

Below is the right user with right file permissions for Drupal:

You might have to change it back once it is transported back to server!

In my case the table was updated correctly, but setNeedDisplay() was not called for the image so I mistakenly thought that the data was not reloaded.

You can import the module and check the module.__file__ string. It contains the path to the associated source file.

Alternatively, you can read the File tag in the the module documentation, which can be accessed using help(module), or module? in IPython.

With pure JavaScript:

console.log(window.location.href)

Using Angular:

this.router.url

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

@Component({
    template: 'The href is: {{href}}'
    /*
    Other component settings
    */
})
export class Component {
    public href: string = "";

    constructor(private router: Router) {}

    ngOnInit() {
        this.href = this.router.url;
        console.log(this.router.url);
    }
}

The plunkr is here: https://plnkr.co/edit/0x3pCOKwFjAGRxC4hZMy?p=preview

You could create a copy of the array and then multiply each element with -1.
As an effect the before largest elements would become the smallest.
The indeces of the n smallest elements in the copy are the n greatest elements in the original.

You can also do it in one row:

if (MessageBox.Show("Text", "Title", MessageBoxButtons.YesNo) == DialogResult.Yes)

And if you want to show a messagebox on top:

if (MessageBox.Show(new Form() { TopMost = true }, "Text", "Text", MessageBoxButtons.YesNo) == DialogResult.Yes)

list = ['aaa', 'bbb', 'ccc']

string = ''.join(list)
print(string)
>>> aaabbbccc

string = ','.join(list)
print(string)
>>> aaa,bbb,ccc

string = '-'.join(list)
print(string)
>>> aaa-bbb-ccc

string = '\n'.join(list)
print(string)
>>> aaa
>>> bbb
>>> ccc

Use this CSS for Modal and modal-dialog

.modal{
    pointer-events: none;
}

.modal-dialog{
    pointer-events: all;
 }

This can resolve your problem in Modal

You need to delegate event to the document level

$(document).on('submit','form.remember',function(){
   // code
});

$('form.remember').on('submit' work same as $('form.remember').submit( but when you use $(document).on('submit','form.remember' then it will also work for the DOM added later.

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

maybe you can use temp list for delete. for ignore row index change

<pre>_x000D_
private void btnDelete_Click(object sender, EventArgs e)_x000D_
{_x000D_
    List<int> wantdel = new List<int>();_x000D_
    foreach (DataGridViewRow row in dataGridView1.Rows)_x000D_
    {_x000D_
        if ((bool)row.Cells["Select"].Value == true)_x000D_
        wantdel.Add(row.Index);_x000D_
    }_x000D_
_x000D_
    wantdel.OrderByDescending(y => y).ToList().ForEach(x =>_x000D_
    {_x000D_
        dataGridView1.Rows.RemoveAt(x);_x000D_
    });           _x000D_
}_x000D_

DBNull.Value is what the .NET Database providers return to represent a null entry in the database. DBNull.Value is not null and comparissons to null for column values retrieved from a database row will not work, you should always compare to DBNull.Value.

I found this much simpler. Simply type this into the terminal:

PATH=$PATH:C:\[pythondir]\scripts 

if x is a vector with raw scores then scale(x) is a vector with standardized scores.

Or manually: (x-mean(x))/sd(x)

Integer is only there for the sql standard ie deprecated by Oracle.

You should use Number instead.

Integers get stored as Number anyway by Oracle behind the scenes.

Most commonly when ints are stored for IDs and such they are defined with no params - so in theory you could look at the scale and precision columns of the metadata views to see of no decimal values can be stored - however 99% of the time this will not help.

As was commented above you could look for number(38,0) columns or similar (ie columns with no decimal points allowed) but this will only tell you which columns cannot take decimals, and not what columns were defined so that INTS can be stored.

Suggestion: do a data profile on the number columns. Something like this:

 select max( case when trunc(column_name,0)=column_name then 0 else 1 end ) as has_dec_vals
 from table_name

I think all you need to display the data on an HTML page is JSON.stringify.

For example, if your JSON is stored like this:

var jsonVar = {
        text: "example",
        number: 1
    };

Then you need only do this to convert it to a string:

var jsonStr = JSON.stringify(jsonVar);

And then you can insert into your HTML directly, for example:

document.body.innerHTML = jsonStr;

Of course you will probably want to replace body with some other element via getElementById.

As for the CSS part of your question, you could use RegExp to manipulate the stringified object before you put it into the DOM. For example, this code (also on JSFiddle for demonstration purposes) should take care of indenting of curly braces.

var jsonVar = {
        text: "example",
        number: 1,
        obj: {
            "more text": "another example"
        },
        obj2: {
             "yet more text": "yet another example"
        }
    }, // THE RAW OBJECT
    jsonStr = JSON.stringify(jsonVar),  // THE OBJECT STRINGIFIED
    regeStr = '', // A EMPTY STRING TO EVENTUALLY HOLD THE FORMATTED STRINGIFIED OBJECT
    f = {
            brace: 0
        }; // AN OBJECT FOR TRACKING INCREMENTS/DECREMENTS,
           // IN PARTICULAR CURLY BRACES (OTHER PROPERTIES COULD BE ADDED)

regeStr = jsonStr.replace(/({|}[,]*|[^{}:]+:[^{}:,]*[,{]*)/g, function (m, p1) {
var rtnFn = function() {
        return '<div style="text-indent: ' + (f['brace'] * 20) + 'px;">' + p1 + '</div>';
    },
    rtnStr = 0;
    if (p1.lastIndexOf('{') === (p1.length - 1)) {
        rtnStr = rtnFn();
        f['brace'] += 1;
    } else if (p1.indexOf('}') === 0) {
         f['brace'] -= 1;
        rtnStr = rtnFn();
    } else {
        rtnStr = rtnFn();
    }
    return rtnStr;
});

document.body.innerHTML += regeStr; // appends the result to the body of the HTML document

This code simply looks for sections of the object within the string and separates them into divs (though you could change the HTML part of that). Every time it encounters a curly brace, however, it increments or decrements the indentation depending on whether it's an opening brace or a closing (behaviour similar to the space argument of 'JSON.stringify'). But you could this as a basis for different types of formatting.

They aren't the same though, are they? One is a copy, the other is a swap. Hence the function names.

My favourite is:

a = b;

Where a and b are vectors.

You can query the data dictionary/catalog views to find out when an object was created as well as the time of last DDL involving the object (example: alter table)

select * 
  from all_objects 
 where owner = '<name of schema owner>'
   and object_name = '<name of table>'

The column "CREATED" tells you when the object was created. The column "LAST_DDL_TIME" tells you when the last DDL was performed against the object.

As for when a particular row was inserted/updated, you can use audit columns like an "insert_timestamp" column or use a trigger and populate an audit table

Since the hosts is blocked. try connect it from other host and execute the mysqladmin flush-hosts command.

mysqladmin -h <RDS ENDPOINT URL> -P <PORT> -u <USER> -p flush-hosts

Are you trying to make something like this?

public List<Car> getAll() {
    return new ArrayList<Car>(cars);
}

And then calling it:

List<Car> cars = c1.getAll();
for (Car item : cars) {   
    System.out.println(item.getMake() + " " + item.getReg());
}

SELECT *
   FROM   my_table
   WHERE  substr(my_field,1,5) = "abcde";

You set the CSS to :

#elementID {
    background: black url(http://www.electrictoolbox.com/images/rangitoto-3072x200.jpg) center no-repeat;
    height: 200px;
}

It centers the image, but does not scale it.

FIDDLE

In newer browsers you can use the background-size property and do:

#elementID {
    height: 200px; 
    width: 100%;
    background: black url(http://www.electrictoolbox.com/images/rangitoto-3072x200.jpg) no-repeat;
    background-size: 100% 100%;
}

FIDDLE

Other than that, a regular image is one way to do it, but then it's not really a background image.

It's the year 2017.

I made some tests.

https://jsperf.com/fastest-way-to-iterate-through-an-array/

Looks like the while method is the fastest on Chrome.

Looks like the left decrement (--i) is much faster than the others (++i, i--, i++) on Firefox.

This approach is the fasted on average. But it iterates the array in reversed order.

let i = array.length;
while (--i >= 0) {
    doSomething(array[i]);
}

If the forward order is important, use this approach.

let ii = array.length;
let i = 0;
while (i < ii) {
    doSomething(array[i]);
    ++i;
}

• After trying everything given above. I found it doesn't matter either you specify
  webView.setBackgroundColor(Color.TRANSPARENT) before or after loadUrl() /loadData().
• The thing that matters is you should explicitly declare android:hardwareAccelerated="false" in the manifest.

Tested on IceCream Sandwich

An HttpOnly cookie means that it's not available to scripting languages like JavaScript. So in JavaScript, there's absolutely no API available to get/set the HttpOnly attribute of the cookie, as that would otherwise defeat the meaning of HttpOnly.

Just set it as such on the server side using whatever server side language the server side is using. If JavaScript is absolutely necessary for this, you could consider to just let it send some (ajax) request with e.g. some specific request parameter which triggers the server side language to create an HttpOnly cookie. But, that would still make it easy for hackers to change the HttpOnly by just XSS and still have access to the cookie via JS and thus make the HttpOnly on your cookie completely useless.

I was having similar problem recently with version 2.6.6.

@JsonInclude(JsonInclude.Include.NON_NULL)

Using above annotation either on filed or class level was not working as expected. The POJO was mutable where I was applying the annotation. When I changed the behaviour of the POJO to be immutable the annotation worked its magic.

I am not sure if its down to new version or previous versions of this lib had similar behaviour but for 2.6.6 certainly you need to have Immutable POJO for the annotation to work.

objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);

Above option mentioned in various answers of setting serialisation inclusion in ObjectMapper directly at global level works as well but, I prefer controlling it at class or filed level.

So if you wanted all the null fields to be ignored while JSON serialisation then use the annotation at class level but if you want only few fields to ignored in a class then use it over those specific fields. This way its more readable & easy for maintenance if you wanted to change behaviour for specific response.

DEMO

You need to find the location of what you're looking for with .indexOf() then remove it with .splice()

function remove(arr, what) {
    var found = arr.indexOf(what);

    while (found !== -1) {
        arr.splice(found, 1);
        found = arr.indexOf(what);
    }
}

var array = new Array();
array.push("A");
array.push("B");
array.push("C");
 ?   
remove(array, 'B');
alert(array)????;

This will take care of all occurrences.

UPLOAD FILES

            $scope.selectedResumeName = f.name;
            $scope.selectedResumeType = f.type;
            r = new FileReader();

            r.onloadend = function (e) { 
                $scope.data = e.target.result;
            }

            r.readAsDataURL(f);

        };

DOWNLOAD FILES:

The above code will be enough.Just paste this into the link you want to remove underline from.

Auto-incrementing the index in a loop:

I'm guessing you are more interested in getting some insight into "why" the cosine similarity works (why it provides a good indication of similarity), rather than "how" it is calculated (the specific operations used for the calculation). If your interest is in the latter, see the reference indicated by Daniel in this post, as well as a related SO Question.

To explain both the how and even more so the why, it is useful, at first, to simplify the problem and to work only in two dimensions. Once you get this in 2D, it is easier to think of it in three dimensions, and of course harder to imagine in many more dimensions, but by then we can use linear algebra to do the numeric calculations and also to help us think in terms of lines / vectors / "planes" / "spheres" in n dimensions, even though we can't draw these.

So, in two dimensions: with regards to text similarity this means that we would focus on two distinct terms, say the words "London" and "Paris", and we'd count how many times each of these words is found in each of the two documents we wish to compare. This gives us, for each document, a point in the the x-y plane. For example, if Doc1 had Paris once, and London four times, a point at (1,4) would present this document (with regards to this diminutive evaluation of documents). Or, speaking in terms of vectors, this Doc1 document would be an arrow going from the origin to point (1,4). With this image in mind, let's think about what it means for two documents to be similar and how this relates to the vectors.

VERY similar documents (again with regards to this limited set of dimensions) would have the very same number of references to Paris, AND the very same number of references to London, or maybe, they could have the same ratio of these references. A Document, Doc2, with 2 refs to Paris and 8 refs to London, would also be very similar, only with maybe a longer text or somehow more repetitive of the cities' names, but in the same proportion. Maybe both documents are guides about London, only making passing references to Paris (and how uncool that city is ;-) Just kidding!!!.

Now, less similar documents may also include references to both cities, but in different proportions. Maybe Doc2 would only cite Paris once and London seven times.

Back to our x-y plane, if we draw these hypothetical documents, we see that when they are VERY similar, their vectors overlap (though some vectors may be longer), and as they start to have less in common, these vectors start to diverge, to have a wider angle between them.

By measuring the angle between the vectors, we can get a good idea of their similarity, and to make things even easier, by taking the Cosine of this angle, we have a nice 0 to 1 or -1 to 1 value that is indicative of this similarity, depending on what and how we account for. The smaller the angle, the bigger (closer to 1) the cosine value, and also the higher the similarity.

At the extreme, if Doc1 only cites Paris and Doc2 only cites London, the documents have absolutely nothing in common. Doc1 would have its vector on the x-axis, Doc2 on the y-axis, the angle 90 degrees, Cosine 0. In this case we'd say that these documents are orthogonal to one another.

Adding dimensions:
With this intuitive feel for similarity expressed as a small angle (or large cosine), we can now imagine things in 3 dimensions, say by bringing the word "Amsterdam" into the mix, and visualize quite well how a document with two references to each would have a vector going in a particular direction, and we can see how this direction would compare to a document citing Paris and London three times each, but not Amsterdam, etc. As said, we can try and imagine the this fancy space for 10 or 100 cities. It's hard to draw, but easy to conceptualize.

I'll wrap up just by saying a few words about the formula itself. As I've said, other references provide good information about the calculations.

First in two dimensions. The formula for the Cosine of the angle between two vectors is derived from the trigonometric difference (between angle a and angle b):

cos(a - b) = (cos(a) * cos(b)) + (sin (a) * sin(b))

This formula looks very similar to the dot product formula:

Vect1 . Vect2 =  (x1 * x2) + (y1 * y2)

where cos(a) corresponds to the x value and sin(a) the y value, for the first vector, etc. The only problem, is that x, y, etc. are not exactly the cos and sin values, for these values need to be read on the unit circle. That's where the denominator of the formula kicks in: by dividing by the product of the length of these vectors, the x and y coordinates become normalized.

For environment variable in Maven, you can set below.

Here are a couple of ways to do it.

Method 1: System.arraycopy():

Copies an array from the specified source array, beginning at the specified position, to the specified position of the destination array. A subsequence of array components are copied from the source array referenced by src to the destination array referenced by dest. The number of components copied is equal to the length argument. The components at positions srcPos through srcPos+length-1 in the source array are copied into positions destPos through destPos+length-1, respectively, of the destination array.

Object[] originalArray = new Object[5];   
Object[] largerArray = new Object[10];
System.arraycopy(originalArray, 0, largerArray, 0, originalArray.length);

Method 2: Arrays.copyOf():

Copies the specified array, truncating or padding with nulls (if necessary) so the copy has the specified length. For all indices that are valid in both the original array and the copy, the two arrays will contain identical values. For any indices that are valid in the copy but not the original, the copy will contain null. Such indices will exist if and only if the specified length is greater than that of the original array. The resulting array is of exactly the same class as the original array.

Object[] originalArray = new Object[5];   
Object[] largerArray = Arrays.copyOf(originalArray, 10);

Note that this method usually uses System.arraycopy() behind the scenes.

Method 3: ArrayList:

Resizable-array implementation of the List interface. Implements all optional list operations, and permits all elements, including null. In addition to implementing the List interface, this class provides methods to manipulate the size of the array that is used internally to store the list. (This class is roughly equivalent to Vector, except that it is unsynchronized.)

ArrayList functions similarly to an array, except it automatically expands when you add more elements than it can contain. It's backed by an array, and uses Arrays.copyOf.

ArrayList<Object> list = new ArrayList<>();

// This will add the element, resizing the ArrayList if necessary.
list.add(new Object());

One option seems to be using CSS to style the textarea

.multi-line { height:5em; width:5em; }

See this entry on SO or this one.

Amurra's accepted answer seems to imply this class is added automatically when using EditorFor but you'd have to verify this.

EDIT: Confirmed, it does. So yes, if you want to use EditorFor, using this CSS style does what you're looking for.

<textarea class="text-box multi-line" id="StoreSearchCriteria_Location" name="StoreSearchCriteria.Location">

lines.map(&:strip).join(" ")

The simplest solution would be to use a subquery for finding the minimum ID matching your query. In the subquery you use GROUP BY instead of DISTINCT:

SELECT * FROM [TestData] WHERE [ID] IN (
   SELECT MIN([ID]) FROM [TestData]
   WHERE [SKU] LIKE 'FOO-%'
   GROUP BY [PRODUCT]
)

Another minimalist Python solution without using numpy:

[0 if i < 0 else i for i in a]

No need to define any extra functions.

a = [1, 2, 3, -4, -5.23, 6]
[0 if i < 0 else i for i in a]

yields:

[1, 2, 3, 0, 0, 6]

IMO, this is personal. I'm not putting any prefixes at all. Anyway, if code is meaned to be public, I think it should better has some prefixes, so it can be more readable.

Often large companies are using it's own so called 'developer rules'.
Btw, the funniest yet smartest i saw was DRY KISS (Dont Repeat Yourself. Keep It Simple, Stupid). :-)

Edit - Contained User (v12 and later)

As of Sql Azure 12, databases will be created as Contained Databases which will allow users to be created directly in your database, without the need for a server login via master.

CREATE USER [MyUser] WITH PASSWORD = 'Secret';
ALTER ROLE [db_datareader] ADD MEMBER [MyUser];

Note when connecting to the database when using a contained user that you must always specify the database in the connection string.

Traditional Server Login - Database User (Pre v 12)

Just to add to @Igorek's answer, you can do the following in Sql Server Management Studio:

Create the new Login on the server
In master (via the Available databases drop down in SSMS - this is because USE master doesn't work in Azure):

create the login:

CREATE LOGIN username WITH password='password';

Create the new User in the database
Switch to the actual database (again via the available databases drop down, or a new connection)

CREATE USER username FROM LOGIN username;

(I've assumed that you want the user and logins to tie up as username, but change if this isn't the case.)

Now add the user to the relevant security roles

EXEC sp_addrolemember N'db_owner', N'username'
GO

(Obviously an app user should have less privileges than dbo.)

A reference is semantically the following:

T& <=> *(T * const)

const T& <=> *(T const * const)

T&& <=> [no C equivalent] (C++11)

As with other answers, the following from the C++ FAQ is the one-line answer: references when possible, pointers when needed.

An advantage over pointers is that you need explicit casting in order to pass NULL. It's still possible, though. Of the compilers I've tested, none emit a warning for the following:

int* p() {
    return 0;
}
void x(int& y) {
  y = 1;
}
int main() {
   x(*p());
}

I run into this issue too. I was including bootstrap.js AND bootstrap-modal.js. If you already have bootstrap.js, you don't need to include popover.

The short answer to this question is that none of these values are a reliable indicator of how much memory an executable is actually using, and none of them are really appropriate for debugging a memory leak.

Private Bytes refer to the amount of memory that the process executable has asked for - not necessarily the amount it is actually using. They are "private" because they (usually) exclude memory-mapped files (i.e. shared DLLs). But - here's the catch - they don't necessarily exclude memory allocated by those files. There is no way to tell whether a change in private bytes was due to the executable itself, or due to a linked library. Private bytes are also not exclusively physical memory; they can be paged to disk or in the standby page list (i.e. no longer in use, but not paged yet either).

Working Set refers to the total physical memory (RAM) used by the process. However, unlike private bytes, this also includes memory-mapped files and various other resources, so it's an even less accurate measurement than the private bytes. This is the same value that gets reported in Task Manager's "Mem Usage" and has been the source of endless amounts of confusion in recent years. Memory in the Working Set is "physical" in the sense that it can be addressed without a page fault; however, the standby page list is also still physically in memory but not reported in the Working Set, and this is why you might see the "Mem Usage" suddenly drop when you minimize an application.

Virtual Bytes are the total virtual address space occupied by the entire process. This is like the working set, in the sense that it includes memory-mapped files (shared DLLs), but it also includes data in the standby list and data that has already been paged out and is sitting in a pagefile on disk somewhere. The total virtual bytes used by every process on a system under heavy load will add up to significantly more memory than the machine actually has.

So the relationships are:

• Private Bytes are what your app has actually allocated, but include pagefile usage;
• Working Set is the non-paged Private Bytes plus memory-mapped files;
• Virtual Bytes are the Working Set plus paged Private Bytes and standby list.

There's another problem here; just as shared libraries can allocate memory inside your application module, leading to potential false positives reported in your app's Private Bytes, your application may also end up allocating memory inside the shared modules, leading to false negatives. That means it's actually possible for your application to have a memory leak that never manifests itself in the Private Bytes at all. Unlikely, but possible.

Private Bytes are a reasonable approximation of the amount of memory your executable is using and can be used to help narrow down a list of potential candidates for a memory leak; if you see the number growing and growing constantly and endlessly, you would want to check that process for a leak. This cannot, however, prove that there is or is not a leak.

One of the most effective tools for detecting/correcting memory leaks in Windows is actually Visual Studio (link goes to page on using VS for memory leaks, not the product page). Rational Purify is another possibility. Microsoft also has a more general best practices document on this subject. There are more tools listed in this previous question.

I hope this clears a few things up! Tracking down memory leaks is one of the most difficult things to do in debugging. Good luck.

I think the annotation you are looking for is:

public class CompanyName implements Serializable {
//...
@JoinColumn(name = "COMPANY_ID", referencedColumnName = "COMPANY_ID", insertable = false, updatable = false)
private Company company;

And you should be able to use similar mappings in a hbm.xml as shown here (in 23.4.2):

http://docs.jboss.org/hibernate/core/3.3/reference/en/html/example-mappings.html

Calling

$state.go($state.current, {myParam: newValue}, {notify: false});

will still reload the controller, meaning you will lose state data.

To avoid it, simply declare the parameter as dynamic:

$stateProvider.state({
    name: 'myState',
    url: '/my_state?myParam',
    params: {
        myParam: {
          dynamic: true,    // <----------
        }
    },
    ...
});

Then you don't even need the notify, just calling

$state.go($state.current, {myParam: newValue})

suffices. Neato!

From the documentation:

When dynamic is true, changes to the parameter value will not cause the state to be entered/exited. The resolves will not be re-fetched, nor will views be reloaded.

This can be useful to build UI where the component updates itself when the param values change.

To add to the above correct answer :- For my case in shell, this code worked (working on sqoop)

ROOT_PATH="path/to/the/folder"
--options-file  $ROOT_PATH/query.txt

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

If you prefer using column names, you could do something like this as an alternative:

min(data$column_name)

It's not a format suitable for blindly copying to another machine, but users who wish to work out whether they've added a repository yet or not (like I did), you can just do:

sudo apt update

When apt is updating, it outputs a list of repositories it fetches. It seems obvious, but I've just realised what the GET URLs are that it spits out.

The following awk-based expression could be used to generate a sources.list file:

 cat /tmp/apt-update.txt | awk '/http/ { gsub("/", " ", $3); gsub("^\s\*$", "main", $3); printf("deb "); if($4 ~ "^[a-z0-9]$") printf("[arch=" $4 "] "); print($2 " " $3) }' | sort | uniq

Alternatively, as other answers suggest, you could just cat all the pre-existing sources like this:

cat /etc/apt/sources.list /etc/apt/sources.list.d/*

Since the disabled repositories are commented out with hash, this should work as intended.

Thanks to KasunBG's tip, I found the solution in the "suggested" link, update the following file (replace 7.x with your Netbeans version) :

C:\Program Files\NetBeans 7.x\etc\netbeans.conf

Change the following line to point it where your java installation is :

netbeans_jdkhome="C:\Program Files\Java\jdk1.7xxxxx"

You may need Administrator privileges to edit netbeans.conf

Either use COUNT in your MySQL query or do a SELECT * FROM table and do:

$result = mysql_query("SELECT * FROM table");
$rows = mysql_num_rows($result);
echo "There are " . $rows . " rows in my table.";

Warnings are annoying. As mentioned in other answers, you can suppress them using:

import warnings
warnings.simplefilter(action='ignore', category=FutureWarning)

But if you want to handle them one by one and you are managing a bigger codebase, it will be difficult to find the line of code which is causing the warning. Since warnings unlike errors don't come with code traceback. In order to trace warnings like errors, you can write this at the top of the code:

import warnings
warnings.filterwarnings("error")

But if the codebase is bigger and it is importing bunch of other libraries/packages, then all sort of warnings will start to be raised as errors. In order to raise only certain type of warnings (in your case, its FutureWarning) as error, you can write:

import warnings
warnings.simplefilter(action='error', category=FutureWarning)

Total control over output with spacing and escape characters.:

echo.    ^<resourceDir^>/%basedir%/resources^</resourceDir^>

if you are using Eclipse. You should switch to DDMS perspective from top-right corner there after selecting your device you can see folder tree. to install apk manually you can use adb command

adb install apklocation.apk

Here is also a good and simple site to check your php codes and share your code with fiends :

http://trycodeonline.com

You can use the function file_get_contents();

if(file_get_contents('https://example.com/example.txt')) {
    //File exists
}

Solution for LAMP users:

apt-get install php5-json
service apache2 restart

Yeah a CSS primer will not hurt here so you can do two things: 1 - within the tags of your html you can open a style tag like this:

<style type="text/css">
  body {
   margin: 0px;
  }
  /*
   * this is the same as writing
   * body { margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;}
   * I'm adding px here for clarity sake but the unit is not really needed if you have 0
   * look into em, pt and % for other unit types 
   * the rules are always clockwise: top, right, bottom, left
  */
</style>

2- the above though will only work on the page you have this code embeded, so if if you wanted to reuse this in 10 files, then you will have to copy it over on all 10 files, and if you wanted to make a change let's say have a margin of 5px instead, you would have to open all those files and make the edit. That's why using an external style sheet is a golden rule in front end coding. So save the body declaration in a separate file named style.css for example and from your add this to your html instead:

<link rel="stylesheet" type="text/css" href="style.css"/>

Now you can put this in the of all pages that will benefit from these styles and whenever needed to change them you will only need to do so in one place. Hope it helps. Cheers

As always, you should question whether you truly need a mutable map.

Immutable maps are trivial to build:

val map = Map(
  "mykey" -> "myval",
  "myotherkey" -> "otherval"
)

Mutable maps are no different when first being built:

val map = collection.mutable.Map(
  "mykey" -> "myval",
  "myotherkey" -> "otherval"
)

map += "nextkey" -> "nextval"

In both of these cases, inference will be used to determine the correct type parameters for the Map instance.

You can also hold an immutable map in a var, the variable will then be updated with a new immutable map instance every time you perform an "update"

var map = Map(
  "mykey" -> "myval",
  "myotherkey" -> "otherval"
)

map += "nextkey" -> "nextval"

If you don't have any initial values, you can use Map.empty:

val map : Map[String, String] = Map.empty //immutable
val map = Map.empty[String,String] //immutable
val map = collection.mutable.Map.empty[String,String] //mutable

You can put CSS in the head of the HTML file, and it will take precedent over a class in an included style sheet.

<style>
.thing{
    color: #f00;
}
</style>

One point missed in the existing answers is show how to inherit the error traps. The bash shell provides one such option for that using set

-E

If set, any trap on ERR is inherited by shell functions, command substitutions, and commands executed in a subshell environment. The ERR trap is normally not inherited in such cases.

Adam Rosenfield's answer recommendation to use set -e is right in certain cases but it has its own potential pitfalls. See GreyCat's BashFAQ - 105 - Why doesn't set -e (or set -o errexit, or trap ERR) do what I expected?

According to the manual, set -e exits

if a simple commandexits with a non-zero status. The shell does not exit if the command that fails is part of the command list immediately following a while or until keyword, part of the test in a if statement, part of an && or || list except the command following the final && or ||, any command in a pipeline but the last, or if the command's return value is being inverted via !".

which means, set -e does not work under the following simple cases (detailed explanations can be found on the wiki)

1. Using the arithmetic operator let or $((..)) ( bash 4.1 onwards) to increment a variable value as

   #!/usr/bin/env bash
   set -e
   i=0
   let i++                   # or ((i++)) on bash 4.1 or later
   echo "i is $i" 
   

2. If the offending command is not part of the last command executed via && or ||. For e.g. the below trap wouldn't fire when its expected to

   #!/usr/bin/env bash
   set -e
   test -d nosuchdir && echo no dir
   echo survived
   

3. When used incorrectly in an if statement as, the exit code of the if statement is the exit code of the last executed command. In the example below the last executed command was echo which wouldn't fire the trap, even though the test -d failed

   #!/usr/bin/env bash
   set -e
   f() { if test -d nosuchdir; then echo no dir; fi; }
   f 
   echo survived
   

4. When used with command-substitution, they are ignored, unless inherit_errexit is set with bash 4.4

   #!/usr/bin/env bash
   set -e
   foo=$(expr 1-1; true)
   echo survived
   

5. when you use commands that look like assignments but aren't, such as export, declare, typeset or local. Here the function call to f will not exit as local has swept the error code that was set previously.

   set -e
   f() { local var=$(somecommand that fails); }        
   g() { local var; var=$(somecommand that fails); }
   

6. When used in a pipeline, and the offending command is not part of the last command. For e.g. the below command would still go through. One options is to enable pipefail by returning the exit code of the first failed process:

   set -e
   somecommand that fails | cat -
   echo survived
   

The ideal recommendation is to not use set -e and implement an own version of error checking instead. More information on implementing custom error handling on one of my answers to Raise error in a Bash script

awk and tools like it (I'm staring at you sed...) should be relegated to the dustbin of old projects, with code that everyone is too afraid to touch since it was written in a read-never language.

Or you're the relatively rare project that needs to prioritize CPU usage optimization over code maintenance optimization... in which case, carry on.

If not, though, why not instead just use something readable and explicit, such as python? Your fellow coders and future self will thank you. You can use python inline with bash just like all the others.

num1=3.17648E-22
num2=1.5
if python -c "exit(0 if $num1 < $num2 else 1)"; then
    echo "yes, $num1 < $num2"
else
    echo "no, $num1 >= $num2"
fi

Vary the consumer-rate and the producer-rate (using sleep), to better understand the operation of code. The code below is the consumer-producer simulation (over a max-limit on container).

Code for your reference:

#include <stdio.h>
#include <pthread.h>
#include <semaphore.h>

sem_t semP, semC;
int stock_count = 0;
const int stock_max_limit=5;

void *producer(void *arg) {
    int i, sum=0;
    for (i = 0; i < 10; i++) {

        while(stock_max_limit == stock_count){
            printf("stock overflow, production on wait..\n");
            sem_wait(&semC);
            printf("production operation continues..\n");
        }

        sleep(1);   //production decided here
        stock_count++;
        printf("P::stock-count : %d\n",stock_count);
        sem_post(&semP);
        printf("P::post signal..\n");
    }
 }

void *consumer(void *arg) {
    int i, sum=0;
    for (i = 0; i < 10; i++) {

        while(0 == stock_count){
            printf("stock empty, consumer on wait..\n");
            sem_wait(&semP);
            printf("consumer operation continues..\n");
        }

        sleep(2);   //consumer rate decided here
        stock_count--;
        printf("C::stock-count : %d\n", stock_count);
        sem_post(&semC);
        printf("C::post signal..\n");
        }
}

int main(void) {

    pthread_t tid0,tid1;
    sem_init(&semP, 0, 0);
    sem_init(&semC, 0, 0);

        pthread_create(&tid0, NULL, consumer, NULL);
        pthread_create(&tid1, NULL, producer, NULL);
        pthread_join(tid0, NULL);
        pthread_join(tid1, NULL);

    sem_destroy(&semC);
    sem_destroy(&semP);

    return 0;
}

if ( $( "#myDiv" ).length ) {
    // if ( "#myDiv" ) is exist this will perform
    $( "#myDiv" ).show();

}

Another shorthand way:

    $( "#myDiv" ).length && $( "#myDiv" ).show();

Just Do

new AlertDialog.Builder(this)

Instead of

new AlertDialog.Builder(getApplicationContext())

System.out.println(list);//toString() is easy and good enough for debugging.

toString() of AbstractCollection will be clean and easy enough to do that. AbstractList is a subclass of AbstractCollection, so no need to for loop and no toArray() needed.

Returns a string representation of this collection. The string representation consists of a list of the collection's elements in the order they are returned by its iterator, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", " (comma and space). Elements are converted to strings as by String.valueOf(Object).

If you are using any custom object in your list, say Student , you need to override its toString() method(it is always good to override this method) to have a meaningful output

See the below example:

public class TestPrintElements {

    public static void main(String[] args) {

        //Element is String, Integer,or other primitive type
        List<String> sList = new ArrayList<String>();
        sList.add("string1");
        sList.add("string2");
        System.out.println(sList);

        //Element is custom type
        Student st1=new Student(15,"Tom");
        Student st2=new Student(16,"Kate");
        List<Student> stList=new ArrayList<Student>();
        stList.add(st1);
        stList.add(st2);
        System.out.println(stList);
   }
}


public  class Student{
    private int age;
    private String name;

    public Student(int age, String name){
        this.age=age;
        this.name=name;
    }

    @Override
    public String toString(){
        return "student "+name+", age:" +age;
    }
}

output:

[string1, string2]
[student Tom age:15, student Kate age:16]

I suggest you to read the Enumeration: Traversing a Collection’s Elements part of the Collections Programming Guide for Cocoa. There is a sample code for your need.

If you're using Java 8 or up, you can use a library I just released: https://github.com/robtimus/try-parse. It has support for int, long and boolean that doesn't rely on catching exceptions. Unlike Guava's Ints.tryParse it returns OptionalInt / OptionalLong / Optional, much like in https://stackoverflow.com/a/38451745/1180351 but more efficient.

POJO:- POJO is a Java object not bound by any restriction other than those forced by the Java Language Specification.

Properties of POJO

1. All properties must be public setter and getter methods
2. All instance variables should be private
3. Should not Extend prespecified classes.
4. Should not Implement prespecified interfaces.
5. Should not contain prespecified annotations.
6. It may not have any argument constructors

Example of POJO

public class POJO {

    private String value;

    public String getValue() {
         return value;
    }

    public void setValue(String value) {
        this.value = value;
    }
}

The context that * is in, confuses the meaning sometimes.

  // when declaring a function
int function(int*); // This function is being declared as a function that takes in an 'address' that holds a number (so int*), it's asking for a 'reference', interchangeably called 'address'. When I 'call'(use) this function later, I better give it a variable-address! So instead of var, or q, or w, or p, I give it the address of var so &var, or &q, or &w, or &p.   

//even though the symbol ' * ' is typically used to mean 'dereferenced variable'(meaning: to use the value at the address of a variable)--despite it's common use, in this case, the symbol means a 'reference', again, in THIS context. (context here being the declaration of a 'prototype'.) 


    //when calling a function
int main(){ 
    function(&var);  // we are giving the function a 'reference', we are giving it an 'address'
  }

So, in the context of declaring a type such as int or char, we would use the dereferencer ' * ' to actually mean the reference (the address), which makes it confusing if you see an error message from the compiler saying: 'expecting char*' which is asking for an address.

In that case, when the * is after a type (int, char, etc.) the compiler is expecting a variable's address. We give it this by using a reference operator, alos called the address-of operator ' & ' before a variable. Even further, in the case I just made up above, the compiler is expecting the address to hold a character value, not a number. (type char * == address of a value that has a character)

int* p;
int *a;   // both are 'pointer' declarations. We are telling the compiler that we will soon give these variables an address (with &).

int c = 10;  //declare and initialize a random variable
//assign the variable to a pointer, we do this so that we can modify the value of c from a different function regardless of the scope of that function (elaboration in a second)

p = c; //ERROR, we assigned a 'value' to this 'pointer'. We need to assign an 'address', a 'reference'.
p = &c; // instead of a value such as: 'q',5,'t', or 2.1 we gave the pointer an 'address', which we could actually print with printf(), and would be something like
//so
p = 0xab33d111; //the address of c, (not specifically this value for the address, it'll look like this though, with the 0x in the beggining, the computer treats these different from regular numbers)
*p = 10; // the value of c

a = &c; // I can still give c another pointer, even though it already has the pointer variable "p"

*a = 10;
 a = 0xab33d111;

Think of each variable as having a position (or an index value if you are familiar with arrays) and a value. It might take some getting used-to to think of each variable having two values to it, one value being it's position, physically stored with electricity in your computer, and a value representing whatever quantity or letter(s) the programmer wants to store.

//Why it's used
int function(b){
    b = b + 1; // we just want to add one to any variable that this function operates on.
} 

int main(){

    int c = 1;  // I want this variable to be 3.

    function(c); 
    function(c);// I call the function I made above twice, because I want c to be 3.

     // this will return c as 1. Even though I called it twice.
     // when you call a function it makes a copy of the variable.
     // so the function that I call "function", made a copy of c, and that function is only changing the "copy" of c, so it doesn't affect the original
}
  //let's redo this whole thing, and use pointers

int function(int* b){ // this time, the function is 'asking' (won't run without) for a variable that 'points' to a number-value (int). So it wants an integer pointer--an address that holds a number.
*b = *b + 1; //grab the value of the address, and add one to the value stored at that address
}

int main(){
    int c = 1; //again, I want this to be three at the end of the program
    int *p = &c; // on the left, I'm declaring a pointer, I'm telling the compiler that I'm about to have this letter point to an certain spot in my computer. Immediately after I used the assignment operator (the ' = ') to assign the address of c to this variable (pointer in this case) p. I do this using the address-of operator (referencer)' & '.
    function(p); // not *p, because that will dereference. which would give an integer, not an integer pointer ( function wants a reference to an int called int*, we aren't going to use *p because that will give the function an int instead of an address that stores an int.

    function(&c); // this is giving the same thing as above, p = the address of c, so we can pass the 'pointer' or we can pass the 'address' that the pointer(variable) is 'pointing','referencing' to. Which is &c. 0xaabbcc1122...


      //now, the function is making a copy of c's address, but it doesn't matter if it's a copy or not, because it's going to point the computer to the exact same spot (hence, The Address), and it will be changed for main's version of c as well.

}

Inside each and every block, it copies the variables (if any) that are passed into (via parameters within "()"s). Within those blocks, the changes to a variable are made to a copy of that variable, the variable uses the same letters but is at a different address (from the original). By using the address "reference" of the original, we can change a variable using a block outside of main, or inside a child of main.

If you have run php artisan config:cache on your server, then your Laravel app could cache outdated config settings that you've put in the .env file.

Run php artisan config:clear to fix that.

Read C# Split String Examples - Dot Net Pearls and the solution can be something like:

var results = yourString.Split(new string[] { "is Marco and" }, StringSplitOptions.None);

To keep encoding and line endings:

Get-Content files.* -Raw | Set-Content newfile.file -NoNewline

Note: AFAIR, whose parameters aren't supported by old Powershells (<3? <4?)

Look at ContentResult. This returns a string, but can be used to make your own BinaryResult-like class.

There may be situations when df.reset_index() cannot be used (e.g., when you need the index, too). In this case, use index.get_level_values() to access index values directly:

df['Trial'] = df.index.get_level_values(0)
df['measurement'] = df.index.get_level_values(1)

This will assign index values to individual columns and keep the index.

See the docs for further info.

How about following commands?

net start "<service name>"
net stop "<service name>"

This can happen if you don't attach your dataset.

Laravel 5.6:

{{ Request::query('parameter') }}

All answers mentioned here are too old and lengthy.The best and short solution that work with latest Navigationview is

@Override
public void onDrawerSlide(View drawerView, float slideOffset) {
    super.onDrawerSlide(drawerView, slideOffset);

    try {
        //int currentapiVersion = android.os.Build.VERSION.SDK_INT;
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
            // Do something for lollipop and above versions

        Window window = getWindow();

        // clear FLAG_TRANSLUCENT_STATUS flag:
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

        // add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

        // finally change the color to any color with transparency

         window.setStatusBarColor(getResources().getColor(R.color.colorPrimaryDarktrans));}

    } catch (Exception e) {

        Crashlytics.logException(e);

    }
}

this is going to change your status bar color to transparent when you open the drawer

Now when you close the drawer you need to change status bar color again to dark.So you can do it in this way.

        public void onDrawerClosed(View drawerView) {
        super.onDrawerClosed(drawerView);
        try {
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
    // Do something for lollipop and above versions

    Window window = getWindow();

    // clear FLAG_TRANSLUCENT_STATUS flag:
    window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

    // add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window
    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

    // finally change the color again to dark
    window.setStatusBarColor(getResources().getColor(R.color.colorPrimaryDark));}
    } catch (Exception e) {
    Crashlytics.logException(e);
                    }
                    }

and then in main layout add a single line i.e

            android:fitsSystemWindows="true"

and your drawer layout will look like

            <android.support.v4.widget.DrawerLayout     
            xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:app="http://schemas.android.com/apk/res-auto"
            xmlns:tools="http://schemas.android.com/tools"
            android:id="@+id/drawer_layout"
            android:fitsSystemWindows="true"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

and your navigation view will look like

    <android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:layout_height="match_parent"
        android:layout_width="wrap_content"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/navigation_header"
        app:menu="@menu/drawer"
        />

I have tested it and its fully working.Hope it helps someone.This may not be the best approach but it works smoothly and is simple to implement. Mark it up if it helps.Happy coding :)

Use HttpServerUtility.UrlEncode

Solution found here : https://sourceforge.net/p/ipt-netflow/bugs-requests-patches/53/

The solution is : $(CURDIR)

You can use it like that :

CUR_DIR = $(CURDIR)

## Start :
start:
    cd $(CUR_DIR)/path_to_folder

Don't mean to beat a dead horse, but there are too many answers here that use tee, which means you have to redirect stdout to /dev/null unless you want to see a copy on the screen.

A simpler solution is to just use cat like this:

sudo ls -hal /root/ | sudo bash -c "cat > /root/test.out"

Notice how the redirection is put inside quotes so that it is evaluated by a shell started by sudo instead of the one running it.

IMO the nicest way is to use the next() function:

router.get('/', function(req, res, next) {
    var err = new Error('Not found');
    err.status = 404;
    return next(err);
}

Then the error is handled by your error handler and you can style the error nicely using HTML.

For the record, be advised that all of the above is (still) true only if the AJAX call is made on the same domain. If you're looking into setting cookies on another domain using AJAX, you're opening a totally different can of worms. Reading cross-domain cookies does work, however (or at least the server serves them; whether your client's UA allows your code to access them is, again, a different topic; as of 2014 they do).

You can see SNS as a traditional topic which you can have multiple Subscribers. You can have heterogeneous subscribers for one given SNS topic, including Lambda and SQS, for example. You can also send SMS messages or even e-mails out of the box using SNS. One thing to consider in SNS is only one message (notification) is received at once, so you cannot take advantage from batching.

SQS, on the other hand, is nothing but a queue, where you store messages and subscribe one consumer (yes, you can have N consumers to one SQS queue, but it would get messy very quickly and way harder to manage considering all consumers would need to read the message at least once, so one is better off with SNS combined with SQS for this use case, where SNS would push notifications to N SQS queues and every queue would have one subscriber, only) to process these messages. As of Jun 28, 2018, AWS Supports Lambda Triggers for SQS, meaning you don't have to poll for messages any more.

Furthermore, you can configure a DLQ on your source SQS queue to send messages to in case of failure. In case of success, messages are automatically deleted (this is another great improvement), so you don't have to worry about the already processed messages being read again in case you forgot to delete them manually. I suggest taking a look at Lambda Retry Behaviour to better understand how it works.

One great benefit of using SQS is that it enables batch processing. Each batch can contain up to 10 messages, so if 100 messages arrive at once in your SQS queue, then 10 Lambda functions will spin up (considering the default auto-scaling behaviour for Lambda) and they'll process these 100 messages (keep in mind this is the happy path as in practice, a few more Lambda functions could spin up reading less than the 10 messages in the batch, but you get the idea). If you posted these same 100 messages to SNS, however, 100 Lambda functions would spin up, unnecessarily increasing costs and using up your Lambda concurrency.

However, if you are still running traditional servers (like EC2 instances), you will still need to poll for messages and manage them manually.

You also have FIFO SQS queues, which guarantee the delivery order of the messages. SQS FIFO is also supported as an event source for Lambda as of November 2019

Even though there's some overlap in their use cases, both SQS and SNS have their own spotlight.

Use SNS if:

• multiple subscribers is a requirement
• sending SMS/E-mail out of the box is handy

Use SQS if:

• only one subscriber is needed
• batching is important

Config is written to .npmrc files so just delete it. NPM looks up config in this order, setting in the next overwrites the previous one. So make sure there might be global config that usually is overwritten in per-project that becomes active after you have deleted the per-project config file. npm config list will allways list the active config.

1. npm builtin config file (/path/to/npm/npmrc)
2. global config file ($PREFIX/etc/npmrc)
3. per-user config file ($HOME/.npmrc)
4. per-project config file (/path/to/my/project/.npmrc)

this simple solution works for me

    final = pd.concat([df, rankingdf], axis=1, sort=False)

but you may need to drop some duplicate column first.

static classes usually are used for libraries, singletons are used if I need only one instance of a particular class. From the point of view of memory there are some differences though: usually in the heap there are allocated only objects, the only methods allocated are methods that are current running. a static class has all methods static too and that will be in the heap from begin, so in general the static class consume more memory.

To help with this I created a function to make this more easy to achieve it.

public static <T> void forEachCurrent(List<T> list, Consumer<T> action) {
    final int size = list.size();
    for (int i = 0; i < size; i++) {
        action.accept(list.get(i));
    }
}

Example

    List<String> l = new ArrayList<>();
    l.add("1");
    l.add("2");
    l.add("3");
    forEachCurrent(l, e -> {
        l.add(e + "A");
        l.add(e + "B");
        l.add(e + "C");
    });
    l.forEach(System.out::println);

This command helped me on linux mint when i had exact same problem

gcc filename.c -L/usr/include -lreadline -o filename

You could use alias if you compile it many times Forexample:

alias compilefilename='gcc filename.c -L/usr/include -lreadline -o filename'

You first need to uninstall the ruby installed by Ubuntu with something like sudo apt-get remove ruby.

Then reinstall ruby using rbenv and ruby-build according to their docs:

cd $HOME
sudo apt-get update 
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev

git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

rbenv install 2.3.1
rbenv global 2.3.1
ruby -v

The last step is to install Bundler:

gem install bundler
rbenv rehash

Then enjoy!

Building on @rprog's answer, you can combine the various pieces of the suffix & filter step into one line using a negative regex:

dfNew = df.merge(df2, left_index=True, right_index=True,
             how='outer', suffixes=('', '_DROP')).filter(regex='^(?!.*_DROP)')

Or using df.join:

dfNew = df.join(df2, lsuffix="DROP").filter(regex="^(?!.*DROP)")

The regex here is keeping anything that does not end with the word "DROP", so just make sure to use a suffix that doesn't appear among the columns already.

Here is a link to VeriSign's SSL Certificate Installation Checker: https://knowledge.verisign.com/support/ssl-certificates-support/index?page=content&id=AR1130

Enter your URL, click "Test this Web Server" and it will tell you if there are issues with your intermediate certificate authority.

In Android Studio open: File > Project Structure and check if JDK location points to your JDK 1.8 directory.

Note: you can use compileSdkVersion 24. It works trust me. For this to work first download latest JDK from Oracle.

This still loops through the cartesian product of the two lists, but it does it one line:

>>> lines1 = ['soup', 'butter', 'venison']
>>> lines2 = ['prune', 'rye', 'turkey']
>>> search_strings = ['a', 'b', 'c']
>>> any(s in l for l in lines1 for s in search_strings)
True
>>> any(s in l for l in lines2 for s in search_strings)
False

This also have the advantage that any short-circuits, and so the looping stops as soon as a match is found. Also, this only finds the first occurrence of a string from search_strings in linesX. If you want to find multiple occurrences you could do something like this:

>>> lines3 = ['corn', 'butter', 'apples']
>>> [(s, l) for l in lines3 for s in search_strings if s in l]
[('c', 'corn'), ('b', 'butter'), ('a', 'apples')]

If you feel like coding something more complex, it seems the Aho-Corasick algorithm can test for the presence of multiple substrings in a given input string. (Thanks to Niklas B. for pointing that out.) I still think it would result in quadratic performance for your use-case since you'll still have to call it multiple times to search multiple lines. However, it would beat the above (cubic, on average) algorithm.

You are right. but here is the simplest way for making the back color of the label transparent In the properties window of that label select Web.. In Web select Transparent :)

Linux:

mvn validate clean install | egrep -v "(^\[INFO\])"

or

mvn validate clean install | egrep -v "(^\[INFO\]|^\[DEBUG\])"

Windows:

mvn validate clean install | findstr /V /R "^\[INFO\] ^\[DEBUG\]"

Alternatively you could use a loop, keep the row number (counter should be the row number) and stop the loop when you find the first "ProjTemp".
Then it should look something like this:

Sub find()
    Dim i As Integer
    Dim firstTime As Integer
    Dim bNotFound As Boolean

    i = 1
    bNotFound = True

      Do While bNotFound
        If Cells(i, 2).Value = "ProjTemp" Then
            firstTime = i
            bNotFound = false
        End If
        i = i + 1
    Loop
End Sub

You need to use HAVING, not WHERE.

The difference is: the WHERE clause filters which rows MySQL selects. Then MySQL groups the rows together and aggregates the numbers for your COUNT function.

HAVING is like WHERE, only it happens after the COUNT value has been computed, so it'll work as you expect. Rewrite your subquery as:

(                  -- where that pid is in the set:
SELECT c2.pid                  -- of pids
FROM Catalog AS c2             -- from catalog
WHERE c2.pid = c1.pid
HAVING COUNT(c2.sid) >= 2)

You can use CSS gradient - although there are not consistent across browsers so You would have to code it for every one

Like that: CSS3 Transparency + Gradient

Gradient should be more transparent on top or on top right corner (depending on capabilities)

You have to be careful when you say "rollback". If you used to have one version of a file in commit $A, and then later made two changes in two separate commits $B and $C (so what you are seeing is the third iteration of the file), and if you say "I want to roll back to the first one", do you really mean it?

If you want to get rid of the changes both the second and the third iteration, it is very simple:

$ git checkout $A file

and then you commit the result. The command asks "I want to check out the file from the state recorded by the commit $A".

On the other hand, what you meant is to get rid of the change the second iteration (i.e. commit $B) brought in, while keeping what commit $C did to the file, you would want to revert $B

$ git revert $B

Note that whoever created commit $B may not have been very disciplined and may have committed totally unrelated change in the same commit, and this revert may touch files other than file you see offending changes, so you may want to check the result carefully after doing so.

LinkedHashMap is precisely what you're looking for.

It is exactly like HashMap, except that when you iterate over it, it presents the items in the insertion order.

It's pretty straightforward using [ to extract:

grep will give you the position in which it matched your search pattern (unless you use value = TRUE).

grep("^G45", My.Data$x)
# [1] 2

Since you're searching within the values of a single column, that actually corresponds to the row index. So, use that with [ (where you would use My.Data[rows, cols] to get specific rows and columns).

My.Data[grep("^G45", My.Data$x), ]
#      x y
# 2 G459 2

The help-page for subset shows how you can use grep and grepl with subset if you prefer using this function over [. Here's an example.

subset(My.Data, grepl("^G45", My.Data$x))
#      x y
# 2 G459 2

As of R 3.3, there's now also the startsWith function, which you can again use with subset (or with any of the other approaches above). According to the help page for the function, it's considerably faster than using substring or grepl.

subset(My.Data, startsWith(as.character(x), "G45"))
#      x y
# 2 G459 2

With modern browsers, you can set the textContent property, see Node.textContent:

var span = document.getElementById("myspan");
span.textContent = "some text";

See the NPM docs and semver docs:

• ~version “Approximately equivalent to version”, will update you to all future patch versions, without incrementing the minor version. ~1.2.3 will use releases from 1.2.3 to <1.3.0.

• ^version “Compatible with version”, will update you to all future minor/patch versions, without incrementing the major version. ^2.3.4 will use releases from 2.3.4 to <3.0.0.

See Comments below for exceptions, in particular for pre-one versions, such as ^0.2.3

There are a lot of different ways to run external commands in Python, and all of them have their own plus sides and drawbacks.

My colleagues and me have been writing Python system administration tools, so we need to run a lot of external commands, and sometimes you want them to block or run asynchronously, time-out, update every second, etc.

There are also different ways of handling the return code and errors, and you might want to parse the output, and provide new input (in an expect kind of style). Or you will need to redirect stdin, stdout and stderr to run in a different tty (e.g., when using screen).

So you will probably have to write a lot of wrappers around the external command. So here is a Python module which we have written which can handle almost anything you would want, and if not, it's very flexible so you can easily extend it:

https://github.com/hpcugent/vsc-base/blob/master/lib/vsc/utils/run.py

update: It doesn't work standalone and requires some of our other tools, and got a lot of specialised functionality over the years, so it might not be a drop in replacement for you, but can give you a lot of info on how the internals of python for running commands work and idea's on how to handle certain situations.

• How can a developer use it?

I didn't find answer for this in the comments, here is how can be used:

1. Don't link your js.map file in your index.html file (no need for that)

2. Minifiacation tools (good ones) add a comment to your .min.js file:

   //# sourceMappingURL=yourFileName.min.js.map

which will connect your .map file.

When the min.js and js.map files are ready...

3. Chrome: Open dev-tools, navigate to Sources tab, You will see sources folder, where un-minified applications files are kept.

boolean entered = false, last;
while (( entered |= last = ( condition ) )) {
        // Do while
} if ( !entered ) {
        // Else
}

You'r welcome.

Check this out: http://wil-linssen.com/entry/extending-the-jquery-sortable-with-ajax-mysql/ I'm using this and I'm happy with the solution.

Right here you can find a demo: http://demo.wil-linssen.com/jquery-sortable-ajax/

This is done using the REPLACE function

To strip out "somestring" from "SomeColumn" in "SomeTable" in the SELECT query:

SELECT REPLACE([SomeColumn],'somestring','') AS [SomeColumn]  FROM [SomeTable]

To update the table and strip out "somestring" from "SomeColumn" in "SomeTable"

UPDATE [SomeTable] SET [SomeColumn] = REPLACE([SomeColumn], 'somestring', '')

In a project of our company we are using "rooms" approach and it's name is a combination of user ids of all users in a conversation as a unique identifier (our implementation is more like facebook messenger), example:

|id | name |1 | Scott |2 | Susan

"room" name will be "1-2" (ids are ordered Asc.) and on disconnect socket.io automatically cleans up the room

this way you send messages just to that room and only to online (connected) users (less packages sent throughout the server).

I would recommend this to anyone looking for missing functionality:

http://code.google.com/p/ddr-ecma5/

It brings in most of the missing ecma5 functionality to older browers :)

 $('#fileupload').bind('change', function (e) { //dynamic property binding
alert('hello');// message you want to display
});

You can use this one also

You can use SHOW:

SHOW max_connections;

This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf in your current session:

RESET max_connections;

However, not applicable to this particular setting. The manual:

This parameter can only be set at server start.

To see all settings:

SHOW ALL;

There is also pg_settings:

The view pg_settings provides access to run-time parameters of the server. It is essentially an alternative interface to the SHOW and SET commands. It also provides access to some facts about each parameter that are not directly available from SHOW, such as minimum and maximum values.

For your original request:

SELECT *
FROM   pg_settings
WHERE  name = 'max_connections';

Finally, there is current_setting(), which can be nested in DML statements:

SELECT current_setting('max_connections');

• How to test my ad-hoc SQL with parameters in Postgres query window

Can't figure out why, but in some circumstances if you have bound DataTimePicker and BindingSource contol is postioned to a new record, setting to Value property doesn't affect to bound field, so when you try to commit changes via EndEdit() method of BindingSource, you receive Null value doesn't allowed error. I managed this problem setting direct DataRow field.

You have to loop through the array and printf() each element:

for(int i=0;i<10;++i) {
  printf("%.2f ", foo[i]);
}

printf("\n");

Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.

>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False

Edit

Further explanation: How does Python compare string and int?

Create a class and give it an __init__ method:

class Student:
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

    def is_old(self):
        return self.age > 100

Now, you can initialize an instance of the Student class:

>>> s = Student('John', 88, None)
>>> s.name
    'John'
>>> s.age
    88

Although I'm not sure why you need a make_student student function if it does the same thing as Student.__init__.

You can select every column from that sub-query by aliasing it and adding the alias before the *:

SELECT t.*, a+b AS total_sum
FROM
(
   SELECT SUM(column1) AS a, SUM(column2) AS b
   FROM table
) t

You don't need negative lookahead. There is working example:

/([\s\S]*?)(red|green|blue|)/g

Description:

• [\s\S] - match any character
• * - match from 0 to unlimited from previous group
• ? - match as less as possible
• (red|green|blue|) - match one of this words or nothing
• g - repeat pattern

Example:

whiteredwhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredwhiteredwhiteredwhiteredwhiteredwhiteredgreenbluewhiteredwhiteredwhiteredwhiteredwhiteredredgreenredgreenredgreenredgreenredgreenbluewhiteredbluewhiteredbluewhiteredbluewhiteredbluewhiteredwhite

Will be:

whitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhitewhite

Test it: regex101.com

You also can use in this form:

<a href="@Url.Action("Information", "Admin", null)"> Admin</a>

Replace whatever is in the address bar with this:

javascript:document.getElementById('serverTime').innerHTML='[text here]';

Example.

We can use relative path instead of absolute path:

$assetPath: '~src/assets/images/';
$logo-img: '#{$assetPath}logo.png';
@mixin logo {
  background-image: url(#{$logo-img});
}

.logo {
    max-width: 65px;
    @include logo;
 }

we can also use

(.*?\n)*?

to match everything including newline without greedy

This will make the new line optional

(.*?|\n)*?

Just for feature readers finding this question. I found that the accepted answer works fine as long as you have a given path, but if you leave it blank it will fail in IE. Here is what I came up with:

function post(path, data, callback) {
    "use strict";
    var request = new XMLHttpRequest();

    if (path === "") {
        path = "/";
    }
    request.open('POST', path, true);
    request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
    request.onload = function (d) {
        callback(d.currentTarget.response);
    };
    request.send(serialize(data));
}

You can you it like so:

post("", {orem: ipsum, name: binny}, function (response) {
    console.log(respone);
})

Unless you're talking about base 16 numbers (for which there's a method to parse as Hex), you need to explicitly separate out the part that you are interested in, and then convert it. After all, what would be the semantics of something like 23e44e11d in base 10?

Regular expressions could do the trick if you know for sure that you only have one number. Java has a built in regular expression parser.

If, on the other hands, your goal is to concatenate all the digits and dump the alphas, then that is fairly straightforward to do by iterating character by character to build a string with StringBuilder, and then parsing that one.

var option = driver.FindElement(By.Id("employmentType"));
        var selectElement = new SelectElement(option);
        Task.Delay(3000).Wait();
        selectElement.SelectByIndex(2);
        Console.Read();

I like to avoid raising a new exception while handling an old one. It makes the error messages confusing to read.

For example, in my code, I originally wrote

try:
    return tuple.__getitem__(self, i)(key)
except IndexError:
    raise KeyError(key)

And I got this message.

>>> During handling of above exception, another exception occurred.

I wanted this:

try:
    return tuple.__getitem__(self, i)(key)
except IndexError:
    pass
raise KeyError(key)

It doesn't affect how exceptions are handled. In either block of code, a KeyError would have been caught. This is merely an issue of getting style points.

The netdom.exe command line program can be used. This is available from the Windows XP Support Tools or Server 2003 Support Tools (both on the installation CD).

If you are not averse to boost, boost.tokenizer is flexible enough to solve this

#include <string>
#include <iostream>
#include <boost/tokenizer.hpp>

void split_and_show(const std::string s)
{
    boost::char_separator<char> sep(" ", "", boost::keep_empty_tokens);
    boost::tokenizer<boost::char_separator<char> > tok(s, sep);
    for(auto i = tok.begin(); i!=tok.end(); ++i)
            std::cout << '"' << *i << "\"\n";
}
int main()
{
    split_and_show("This is a string");
    split_and_show("This  is a string");

Your json contains an array, but you're trying to parse it as an object. This error occurs because objects must start with {.

You have 2 options:

1. You can get rid of the ShopContainer class and use Shop[] instead

   ShopContainer response  = restTemplate.getForObject(
       url, ShopContainer.class);
   

   replace with

   Shop[] response  = restTemplate.getForObject(url, Shop[].class);
   

   and then make your desired object from it.

2. You can change your server to return an object instead of a list

   return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(list);
   

   replace with

   return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(
       new ShopContainer(list));
   

I'm using Mongoose to connect to mongodb. Install mongoose npm using following command

npm install mongoose

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/database_name', function(err){
    if(err){
        console.log('database not connected');
    }
});
var Schema = mongoose.Schema;
var userschema = new Schema ({});
var user = mongoose.model('collection_name', userschema);

we can use the queries like this

user.find({},function(err,data){
         if(err){
         console.log(err);
         }
        console.log(data);
    });

Below query worked for me with default value false;

ALTER TABLE cti_contract_account ADD ready_to_audit BIT DEFAULT 0 NOT NULL;

ORDER BY article_rating ASC , article_time DESC

DESC at the end will sort by both columns descending. You have to specify ASC if you want it otherwise

The field nbytes will give you the size in bytes of all the elements of the array in a numpy.array:

size_in_bytes = my_numpy_array.nbytes

Notice that this does not measures "non-element attributes of the array object" so the actual size in bytes can be a few bytes larger than this.

Although it might look out of topic nobody bothered to check the ERRORLEVEL. When I used your suggestions I tried to check for errors straight after the MSI installation. I made it fail on purpose and noticed that on the command line all works beautifully whilst in a batch file msiexec dosn't seem to set errors. Tried different things there like

• Using start /wait
• Using !ERRORLEVEL! variable instead of %ERRORLEVEL%
• Using SetLocal EnableDelayedExpansion

Nothing works and what mostly annoys me it's the fact that it works in the command line.

If you're on Windows then it's a total no-brainer: Get Visual C++ Express.

You can also implement like this to return Success and Error on a same request mapping method,use Object class(Parent class of every class in java) :-

public ResponseEntity< Object> method() {                                                                                                                                                                                                                                                                                                                                                                                  
    boolean b = //  logic  here   
      if (b)  
        return new ResponseEntity< Object>(HttpStatus.OK);      
    else      
        return new ResponseEntity< Object>(HttpStatus.CONFLICT); //appropriate error code   
}

$("#containerDiv").animate({ scrollTop: 0 }, "fast");

A few things here...

If you want to call a function when the onclick event happens, you'll just want the function name plus the parameters.

Then if your parameters are a variable (which they look like they are), then you won't want quotes around them. Not only that, but if these are global variables, you'll want to add in "window." before that, because that's the object that holds all global variables.

Lastly, if these parameters aren't variables, you'll want to exclude the slashes to escape those characters. Since the value of onclick is wrapped by double quotes, single quotes won't be an issue. So your answer will look like this...

<a href=# onclick="ReAssign('valuationId', window.user)">Re-Assign</a>

There are a few extra things to note here, if you want more than a quick solution.

You looked like you were trying to use the + operator to combine strings in HTML. HTML is a scripting language, so when you're writing it, the whole thing is just a string itself. You can just skip these from now on, because it's not code your browser will be running (just a whole bunch of stuff, and anything that already exists is what has special meaning by the browser).

Next, you're using an anchor tag/link that doesn't actually take the user to another website, just runs some code. I'd use something else other than an anchor tag, with the appropriate CSS to format it to look the way you want. It really depends on the setting, but in many cases, a span tag will do. Give it a class (like class="runjs") and have a rule of CSS for that. To get it to imitate a link's behavior, use this:

.runjs {
    cursor: pointer;
    text-decoration: underline;
    color: blue;
}

This lets you leave out the href attribute which you weren't using anyways.

Last, you probably want to use JavaScript to set the value of this link's onclick attribute instead of hand writing it. It keeps your page cleaner by keeping the code of your page separate from what the structure of your page. In your class, you could change all these links like this...

var links = document.getElementsByClassName('runjs');
for(var i = 0; i < links.length; i++)
    links[i].onclick = function() { ReAssign('valuationId', window.user); };

While this won't work in some older browsers (because of the getElementsByClassName method), it's just three lines and does exactly what you're looking for. Each of these links has an anonymous function tied to them meaning they don't have any variable tied to them except that tag's onclick value. Plus if you wanted to, you could include more lines of code this way, all grouped up in one tidy location.

I know you asked for GET and POST but I will provide CRUD since others may need this just in case: (this was tested in Python 3.7)

#!/usr/bin/env python3
import http.client
import json

print("\n GET example")
conn = http.client.HTTPSConnection("httpbin.org")
conn.request("GET", "/get")
response = conn.getresponse()
data = response.read().decode('utf-8')
print(response.status, response.reason)
print(data)


print("\n POST example")
conn = http.client.HTTPSConnection('httpbin.org')
headers = {'Content-type': 'application/json'}
post_body = {'text': 'testing post'}
json_data = json.dumps(post_body)
conn.request('POST', '/post', json_data, headers)
response = conn.getresponse()
print(response.read().decode())
print(response.status, response.reason)


print("\n PUT example ")
conn = http.client.HTTPSConnection('httpbin.org')
headers = {'Content-type': 'application/json'}
post_body ={'text': 'testing put'}
json_data = json.dumps(post_body)
conn.request('PUT', '/put', json_data, headers)
response = conn.getresponse()
print(response.read().decode(), response.reason)
print(response.status, response.reason)


print("\n delete example")
conn = http.client.HTTPSConnection('httpbin.org')
headers = {'Content-type': 'application/json'}
post_body ={'text': 'testing delete'}
json_data = json.dumps(post_body)
conn.request('DELETE', '/delete', json_data, headers)
response = conn.getresponse()
print(response.read().decode(), response.reason)
print(response.status, response.reason)

• Method 1 has slightly better support - you have to set the width OR height of image!
• With the prefixes method 2 also has decent support ( from ie9 up ) - Method 2 has no support on Opera mini!
• Method 3 uses two wrappers - can overflow width AND height.
• Method 4 uses a double image ( one as placeholder ) this gives some extra bandwidth overhead, but even better crossbrowser support.

Method 1 and 3 don't seem to work with Firefox

I faced a similar problem but in my case I was trying to install Visual C++ Redistributable for Visual Studio 2015 Update 1 on Windows Server 2012 R2. However the root cause should be the same.

In short, you need to install the prerequisites of KB2999226.

In more details, the installation log I got stated that the installation for Windows Update KB2999226 failed. According to the Microsoft website here:

Prerequisites To install this update, you must have April 2014 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 (2919355) installed in Windows 8.1 or Windows Server 2012 R2. Or, install Service Pack 1 for Windows 7 or Windows Server 2008 R2. Or, install Service Pack 2 for Windows Vista and for Windows Server 2008.

After I have installed April 2014 on my Windows Server 2012 R2, I am able to install the Visual C++ Redistributable correctly.

I think these are the main differences

• readability of the code
• control over what is your code doing

Readability can make the code improved or substituted 6 months after it was created with litte effort, on the other hand, if performance is critical you may want to use a low level language to target the specific hardware you will have in production, so to get faster execution.

IMO today computers are fast enough to let a programmer gain fast execution with OOP.

If you're just trying to replace one property, lodash _.find and _.set should be enough:

var arr = [{id: 1, name: "Person 1"}, {id: 2, name: "Person 2"}];

_.set(_.find(arr, {id: 1}), 'name', 'New Person');

Normally, When you copy a cell you will find the below statement written down in the status bar (in the bottom of your sheet)

"Select destination and Press Enter or Choose Paste"

Then you press whether Enter or choose paste to paste the value of the cell.

If you didn't press Esc afterwards you will be able to paste the value of the cell several times

Application.CutCopyMode = False does the same like the Esc button, if you removed it from your code you will find that you are able to paste the cell value several times again.

And if you closed the Excel without pressing Esc you will get the warning 'There is a large amount of information on the Clipboard....'

starting from mihai-labo's answer, why not skip declaring the requrl variable altogether and put the url generating code directly in front of "url:", like:

 $.ajax({
    type: "POST",
    url: '@Url.Action("Action", "Controller", null, Request.Url.Scheme, null)',
    data: "{queryString:'" + searchVal + "'}",
    contentType: "application/json; charset=utf-8",
    dataType: "html",
    success: function (data) {
        alert("here" + data.d.toString());
    }
});

Load your "base" environment -- as OP's py34 -- when you load your terminal/shell.

If you use Bash, put the line:

conda activate py34

in your .bash_profile (or .bashrc):

$ echo 'conda activate py34' >> ~/.bash_profile

Every time you run a new terminal, conda environment py34 will be loaded.

For:

1) mat-select (selectionChange)="myFunction()" works in angular as:

sample.component.html

 <mat-select placeholder="Select your option" [(ngModel)]="option" name="action" 
      (selectionChange)="onChange()">
     <mat-option *ngFor="let option of actions" [value]="option">
       {{option}}
     </mat-option>
 </mat-select>

sample.component.ts

actions=['A','B','C'];
onChange() {
  //Do something
}

2) Simple html select (change)="myFunction()" works in angular as:

sample.component.html

<select (change)="onChange()" [(ngModel)]="regObj.status">
    <option>A</option>
    <option>B</option>
    <option>C</option>
</select>

sample.component.ts

onChange() {
  //Do something
}

To execute a method you need to add parentheses, even if the method does not take arguments.

So it should be:

string t = obj.getTitle();

When i use apt install python3-pip, i get a lot of packages need install, but i donot need them. So, i DO like this:

apt update
apt-get install python3-setuptools
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py
rm -f get-pip.py

complete executes after either the success or error callback were executed.

Maybe you should check the second parameter complete offers too. It's a String holding the type of success the ajaxCall had.

The different callbacks are described a little more in detail here jQuery.ajax( options )

I guess you missed the fact that the complete and the success function (I know inconsistent API) get different data passed in. success gets only the data, complete gets the whole XMLHttpRequest object. Of course there is no responseText property on the data string.

So if you replace complete with success you also have to replace data.responseText with data only.

success

The function gets passed two arguments: The data returned from the server, formatted according to the 'dataType' parameter, and a string describing the status.

complete

The function gets passed two arguments: The XMLHttpRequest object and a string describing the type of success of the request.

If you need to have access to the whole XMLHttpRequest object in the success callback I suggest trying this.

var myXHR = $.ajax({
    ...
    success: function(data, status) {
        ...do whatever with myXHR; e.g. myXHR.responseText...
    },
    ...
});

If you are using one of the built-in controller instances, then one of the parameters to your controller method will be the Request object. You can call request.getParameter("value1") to get the POST (or PUT) data value.

If you are using Spring MVC annotations, you can add an annotated parameter to your method's parameters:

@RequestMapping(value = "/someUrl")
public String someMethod(@RequestParam("value1") String valueOne) {
 //do stuff with valueOne variable here
}

Migrating from Glyphicons to Font Awesome is quite easy.

Include a reference to Font Awesome (either locally, or use the CDN).

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">

Then run a search and replace where you search for glyphicon glyphicon- and replace it with fa fa-, and also change the enclosing element from <span to <i. Most of the CSS class names are the same. Some have changed though, so you have to manually fix those.

calling a function is simple ..

 myFunction();

so your code will be something like..

 $(function(){
     $('#elementID').click(function(){
         myFuntion();  //this will call your function
    });
 });

  $(function(){
     $('#elementID').click( myFuntion );

 });

or with some condition

if(something){
   myFunction();  //this will call your function
}

This is my recommended approach.

To promote reusability, I'd say create a category of CAGradientLayer and add your desired gradients as class methods. Specify them in the header file like this :

#import <QuartzCore/QuartzCore.h>

@interface CAGradientLayer (SJSGradients)

+ (CAGradientLayer *)redGradientLayer;
+ (CAGradientLayer *)blueGradientLayer;
+ (CAGradientLayer *)turquoiseGradientLayer;
+ (CAGradientLayer *)flavescentGradientLayer;
+ (CAGradientLayer *)whiteGradientLayer;
+ (CAGradientLayer *)chocolateGradientLayer;
+ (CAGradientLayer *)tangerineGradientLayer;
+ (CAGradientLayer *)pastelBlueGradientLayer;
+ (CAGradientLayer *)yellowGradientLayer;
+ (CAGradientLayer *)purpleGradientLayer;
+ (CAGradientLayer *)greenGradientLayer;

@end

Then in your implementation file, specify each gradient with this syntax :

+ (CAGradientLayer *)flavescentGradientLayer
{
    UIColor *topColor = [UIColor colorWithRed:1 green:0.92 blue:0.56 alpha:1];
    UIColor *bottomColor = [UIColor colorWithRed:0.18 green:0.18 blue:0.18 alpha:1];

    NSArray *gradientColors = [NSArray arrayWithObjects:(id)topColor.CGColor, (id)bottomColor.CGColor, nil];
    NSArray *gradientLocations = [NSArray arrayWithObjects:[NSNumber numberWithInt:0.0],[NSNumber numberWithInt:1.0], nil];

    CAGradientLayer *gradientLayer = [CAGradientLayer layer];
    gradientLayer.colors = gradientColors;
    gradientLayer.locations = gradientLocations;

    return gradientLayer;
}

Then simply import this category in your ViewController or any other required subclass, and use it like this :

CAGradientLayer *backgroundLayer = [CAGradientLayer purpleGradientLayer];
backgroundLayer.frame = self.view.frame;
[self.view.layer insertSublayer:backgroundLayer atIndex:0];

what about the retrying library on pypi? I have been using it for a while and it does exactly what I want and more (retry on error, retry when None, retry with timeout). Below is example from their website:

import random
from retrying import retry

@retry
def do_something_unreliable():
    if random.randint(0, 10) > 1:
        raise IOError("Broken sauce, everything is hosed!!!111one")
    else:
        return "Awesome sauce!"

print do_something_unreliable()

adb push [file path on your computer] [file path on your mobile]

You can set it at Property > Configuration Properties > Debugging > Environment

It means not equal to. The same as != seen in C style languages, as well as actionscript.

I have a GitHub gist contains PHP functions to minify HTML, CSS and JS files → https://gist.github.com/taufik-nurrohman/d7b310dea3b33e4732c0

Here’s how to minify the HTML output on the fly with output buffer:

<?php

include 'path/to/php-html-css-js-minifier.php';

ob_start('minify_html');

?>

<!-- HTML code goes here ... -->

<?php echo ob_get_clean(); ?>

Another alternative is HikariCP.

Here is the comparison benchmark

try block should be around open. Not around prompt.

while True:
    prompt = input("\n Hello to Sudoku valitator,"
    "\n \n Please type in the path to your file and press 'Enter': ")
    try:
        sudoku = open(prompt, 'r').readlines()
    except FileNotFoundError:
        print("Wrong file or file path")
    else:
        break

var jsonIssues = []; // new Array
jsonIssues.push( { ID:1, "Name":"whatever" } );
// "push" some more here

Try setting a Windows System Environment variable called _JAVA_OPTIONS with the heap size you want. Java should be able to find it and act accordingly.

1) in a query window in SQL Server Management Studio, run the command:

SET SHOWPLAN_ALL ON

2) run your slow query

3) your query will not run, but the execution plan will be returned. store this output

4) run your fast version of the query

5) your query will not run, but the execution plan will be returned. store this output

6) compare the slow query version output to the fast query version output.

7) if you still don't know why one is slower, post both outputs in your question (edit it) and someone here can help from there.

I got this issue when I used an ajax call to retrieve data from the database. When the controller returned the array it converted it to a boolean. The problem was that I had "invalid characters" like ú (u with accent).

I did most of the suggested stuff here, still didnt work. Tried this and it worked: Open your XAMPP Control Panel, locate the Config button for the Apache module. Click on the Config button and Select PHP (php.ini). Open with any text editor and remove the semi-column before php_openssl. Save and Restart Apache. That should do!

It just needs to be in the classpath (aka make sure it ends up under /WEB-INF/classes in the .war as part of the build).

if you get error: Committing is not possible because you have unmerged files.

git checkout master
git merge --squash bugfix
git add .
git commit -m "Message"

fixed all the Conflict files

git add . 

you could also use

git add [filename]

Below Code only works if It contain Unique Value Data

public string getKey(string Value)
{
    if (dictionary.ContainsValue(Value))
    {
        var ListValueData=new List<string>();
        var ListKeyData = new List<string>();

        var Values = dictionary.Values;
        var Keys = dictionary.Keys;

        foreach (var item in Values)
        {
            ListValueData.Add(item);
        }

        var ValueIndex = ListValueData.IndexOf(Value);
        foreach (var item in Keys)
        {
            ListKeyData.Add(item);
        }

        return  ListKeyData[ValueIndex];

    }
    return string.Empty;
}

NOTE: Doesn't work on newer versions of jQuery.

Since you are using jQuery please use it's seralize function to serialize data and then pass it into the data parameter of ajax call:

info[0] = 'hi';
info[1] = 'hello';

var data_to_send = $.serialize(info);

$.ajax({
    type: "POST",
    url: "index.php",
    data: data_to_send,
    success: function(msg){
        $('.answer').html(msg);
    }
});

Conditional statements are used to perform different actions based on different conditions.

Use if to specify a block of code to be executed, if a specified condition is true

Use else to specify a block of code to be executed, if the same condition is false

Use else if to specify a new condition to test, if the first condition is false

Recently google has implemented a change on their systems, and since you have uploaded at least one APK to your console, you can test your in-app requests with your app with any version code / number.

This answer is for anyone encountering pdfs with images and needing to use OCR. I could not find a workable off-the-shelf solution; nothing that gave me the accuracy I needed.

Here are the steps I found to work.

1. Use pdfimages from https://poppler.freedesktop.org/ to turn the pages of the pdf into images.

2. Use Tesseract to detect rotation and ImageMagick mogrify to fix it.

3. Use OpenCV to find and extract tables.

4. Use OpenCV to find and extract each cell from the table.

5. Use OpenCV to crop and clean up each cell so that there is no noise that will confuse OCR software.

6. Use Tesseract to OCR each cell.

7. Combine the extracted text of each cell into the format you need.

I wrote a python package with modules that can help with those steps.

Repo: https://github.com/eihli/image-table-ocr

Docs & Source: https://eihli.github.io/image-table-ocr/pdf_table_extraction_and_ocr.html

Some of the steps don't require code, they take advantage of external tools like pdfimages and tesseract. I'll provide some brief examples for a couple of the steps that do require code.

2. Finding tables:

This link was a good reference while figuring out how to find tables. https://answers.opencv.org/question/63847/how-to-extract-tables-from-an-image/

import cv2

def find_tables(image):
    BLUR_KERNEL_SIZE = (17, 17)
    STD_DEV_X_DIRECTION = 0
    STD_DEV_Y_DIRECTION = 0
    blurred = cv2.GaussianBlur(image, BLUR_KERNEL_SIZE, STD_DEV_X_DIRECTION, STD_DEV_Y_DIRECTION)
    MAX_COLOR_VAL = 255
    BLOCK_SIZE = 15
    SUBTRACT_FROM_MEAN = -2

    img_bin = cv2.adaptiveThreshold(
        ~blurred,
        MAX_COLOR_VAL,
        cv2.ADAPTIVE_THRESH_MEAN_C,
        cv2.THRESH_BINARY,
        BLOCK_SIZE,
        SUBTRACT_FROM_MEAN,
    )
    vertical = horizontal = img_bin.copy()
    SCALE = 5
    image_width, image_height = horizontal.shape
    horizontal_kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (int(image_width / SCALE), 1))
    horizontally_opened = cv2.morphologyEx(img_bin, cv2.MORPH_OPEN, horizontal_kernel)
    vertical_kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (1, int(image_height / SCALE)))
    vertically_opened = cv2.morphologyEx(img_bin, cv2.MORPH_OPEN, vertical_kernel)

    horizontally_dilated = cv2.dilate(horizontally_opened, cv2.getStructuringElement(cv2.MORPH_RECT, (40, 1)))
    vertically_dilated = cv2.dilate(vertically_opened, cv2.getStructuringElement(cv2.MORPH_RECT, (1, 60)))

    mask = horizontally_dilated + vertically_dilated
    contours, hierarchy = cv2.findContours(
        mask, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE,
    )

    MIN_TABLE_AREA = 1e5
    contours = [c for c in contours if cv2.contourArea(c) > MIN_TABLE_AREA]
    perimeter_lengths = [cv2.arcLength(c, True) for c in contours]
    epsilons = [0.1 * p for p in perimeter_lengths]
    approx_polys = [cv2.approxPolyDP(c, e, True) for c, e in zip(contours, epsilons)]
    bounding_rects = [cv2.boundingRect(a) for a in approx_polys]

    # The link where a lot of this code was borrowed from recommends an
    # additional step to check the number of "joints" inside this bounding rectangle.
    # A table should have a lot of intersections. We might have a rectangular image
    # here though which would only have 4 intersections, 1 at each corner.
    # Leaving that step as a future TODO if it is ever necessary.
    images = [image[y:y+h, x:x+w] for x, y, w, h in bounding_rects]
    return images

3. Extract cells from table.

This is very similar to 2, so I won't include all the code. The part I will reference will be in sorting the cells.

We want to identify the cells from left-to-right, top-to-bottom.

We’ll find the rectangle with the most top-left corner. Then we’ll find all of the rectangles that have a center that is within the top-y and bottom-y values of that top-left rectangle. Then we’ll sort those rectangles by the x value of their center. We’ll remove those rectangles from the list and repeat.

def cell_in_same_row(c1, c2):
    c1_center = c1[1] + c1[3] - c1[3] / 2
    c2_bottom = c2[1] + c2[3]
    c2_top = c2[1]
    return c2_top < c1_center < c2_bottom

orig_cells = [c for c in cells]
rows = []
while cells:
    first = cells[0]
    rest = cells[1:]
    cells_in_same_row = sorted(
        [
            c for c in rest
            if cell_in_same_row(c, first)
        ],
        key=lambda c: c[0]
    )

    row_cells = sorted([first] + cells_in_same_row, key=lambda c: c[0])
    rows.append(row_cells)
    cells = [
        c for c in rest
        if not cell_in_same_row(c, first)
    ]

# Sort rows by average height of their center.
def avg_height_of_center(row):
    centers = [y + h - h / 2 for x, y, w, h in row]
    return sum(centers) / len(centers)

rows.sort(key=avg_height_of_center)

When you concatenate strings, you need to allocate memory to store the result. The easiest to start with is String and &str:

fn main() {
    let mut owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    owned_string.push_str(borrowed_string);
    println!("{}", owned_string);
}

Here, we have an owned string that we can mutate. This is efficient as it potentially allows us to reuse the memory allocation. There's a similar case for String and String, as &String can be dereferenced as &str.

fn main() {
    let mut owned_string: String = "hello ".to_owned();
    let another_owned_string: String = "world".to_owned();
    
    owned_string.push_str(&another_owned_string);
    println!("{}", owned_string);
}

After this, another_owned_string is untouched (note no mut qualifier). There's another variant that consumes the String but doesn't require it to be mutable. This is an implementation of the Add trait that takes a String as the left-hand side and a &str as the right-hand side:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    let new_owned_string = owned_string + borrowed_string;
    println!("{}", new_owned_string);
}

Note that owned_string is no longer accessible after the call to +.

What if we wanted to produce a new string, leaving both untouched? The simplest way is to use format!:

fn main() {
    let borrowed_string: &str = "hello ";
    let another_borrowed_string: &str = "world";
    
    let together = format!("{}{}", borrowed_string, another_borrowed_string);

    // After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
    // let together = format!("{borrowed_string}{another_borrowed_string}");

    println!("{}", together);
}

Note that both input variables are immutable, so we know that they aren't touched. If we wanted to do the same thing for any combination of String, we can use the fact that String also can be formatted:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let another_owned_string: String = "world".to_owned();
    
    let together = format!("{}{}", owned_string, another_owned_string);

    // After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
    // let together = format!("{owned_string}{another_owned_string}");
    println!("{}", together);
}

You don't have to use format! though. You can clone one string and append the other string to the new string:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    let together = owned_string.clone() + borrowed_string;
    println!("{}", together);
}

Note - all of the type specification I did is redundant - the compiler can infer all the types in play here. I added them simply to be clear to people new to Rust, as I expect this question to be popular with that group!

I was surprised that no one had yet recommended using the builtin filter function.

    import operator
    import string # only for the example you could use a custom string

    s = "1212edjaq"

Say we want to filter out everything that isn't a number. Using the filter builtin method "...is equivalent to the generator expression (item for item in iterable if function(item))" [Python 3 Builtins: Filter]

    sList = list(s)
    intsList = list(string.digits)
    obj = filter(lambda x: operator.contains(intsList, x), sList)))

In Python 3 this returns

    >>  <filter object @ hex>

To get a printed string,

    nums = "".join(list(obj))
    print(nums)
    >> "1212"

I am not sure how filter ranks in terms of efficiency but it is a good thing to know how to use when doing list comprehensions and such.

UPDATE

Logically, since filter works you could also use list comprehension and from what I have read it is supposed to be more efficient because lambdas are the wall street hedge fund managers of the programming function world. Another plus is that it is a one-liner that doesnt require any imports. For example, using the same string 's' defined above,

      num = "".join([i for i in s if i.isdigit()])

That's it. The return will be a string of all the characters that are digits in the original string.

If you have a specific list of acceptable/unacceptable characters you need only adjust the 'if' part of the list comprehension.

      target_chars = "".join([i for i in s if i in some_list]) 

or alternatively,

      target_chars = "".join([i for i in s if i not in some_list])

Alright, so I got it working by changing this

log4j.rootLogger=DebugAppender

to this

log4j.rootLogger=DEBUG, DebugAppender

Apparently you have to specify the logging level to the rootLogger first? I apologize if I wasted anyone's time.

Also, I decided to answer my own question because this wasn't a classpath issue.

Try this, it works for me

select (column1 || ' '|| column2) from table;

nohup some_command > /dev/null 2>&1&

That's all you need to do!

Looking at the select2 docs you use the below to get/set the value.

$("#select").select2("val"); //get the value
$("#select").select2("val", "CA"); //set the value

@PanPipes has pointed out that this has changed for 4.x (go toss him an upvote below). val is now called directly

$("#select").val("CA");

So within the loadComplete of the jqGrid you can get whatever value you are looking for then set the selectbox value.

Notice from the docs

Notice that in order to use this method you must define the initSelection function in the options so Select2 knows how to transform the id of the object you pass in val() to the full object it needs to render selection. If you are attaching to a select element this function is already provided for you.

Explicit access to module level variables by accessing them explicity on the module

In short: The technique described here is the same as in steveha's answer, except, that no artificial helper object is created to explicitly scope variables. Instead the module object itself is given a variable pointer, and therefore provides explicit scoping upon access from everywhere. (like assignments in local function scope).

Think of it like self for the current module instead of the current instance !

# db.py
import sys

# this is a pointer to the module object instance itself.
this = sys.modules[__name__]

# we can explicitly make assignments on it 
this.db_name = None

def initialize_db(name):
    if (this.db_name is None):
        # also in local function scope. no scope specifier like global is needed
        this.db_name = name
        # also the name remains free for local use
        db_name = "Locally scoped db_name variable. Doesn't do anything here."
    else:
        msg = "Database is already initialized to {0}."
        raise RuntimeError(msg.format(this.db_name))

As modules are cached and therefore import only once, you can import db.py as often on as many clients as you want, manipulating the same, universal state:

# client_a.py
import db

db.initialize_db('mongo')

# client_b.py
import db

if (db.db_name == 'mongo'):
    db.db_name = None  # this is the preferred way of usage, as it updates the value for all clients, because they access the same reference from the same module object

# client_c.py
from db import db_name
# be careful when importing like this, as a new reference "db_name" will
# be created in the module namespace of client_c, which points to the value 
# that "db.db_name" has at import time of "client_c".

if (db_name == 'mongo'):  # checking is fine if "db.db_name" doesn't change
    db_name = None  # be careful, because this only assigns the reference client_c.db_name to a new value, but leaves db.db_name pointing to its current value.

As an additional bonus I find it quite pythonic overall as it nicely fits Pythons policy of Explicit is better than implicit.

The datetime class has a method strftime. The Python docs documents the different formats it accepts:

• Python 2: strftime() Behavior
• Python 3: strftime() Behavior

For this specific example, it would look something like:

my_datetime.strftime("%B %d, %Y")

I just posted a kind of a RFC that might help you: Split a vector into chunks in R

x = data.frame(num = 1:26, let = letters, LET = LETTERS)
## number of chunks
n <- 2
dfchunk <- split(x, factor(sort(rank(row.names(x))%%n)))
dfchunk
$`0`
   num let LET
1    1   a   A
2    2   b   B
3    3   c   C
4    4   d   D
5    5   e   E
6    6   f   F
7    7   g   G
8    8   h   H
9    9   i   I
10  10   j   J
11  11   k   K
12  12   l   L
13  13   m   M

$`1`
   num let LET
14  14   n   N
15  15   o   O
16  16   p   P
17  17   q   Q
18  18   r   R
19  19   s   S
20  20   t   T
21  21   u   U
22  22   v   V
23  23   w   W
24  24   x   X
25  25   y   Y

I found an easy solution like this:

class ToggleSwitch extends Component {
  static id;

  constructor(props) {
    super(props);

    if (typeof ToggleSwitch.id === 'undefined') {
      ToggleSwitch.id = 0;
    } else {
      ToggleSwitch.id += 1;
    }
    this.id = ToggleSwitch.id;
  }

  render() {
    return (
        <input id={`prefix-${this.id}`} />
    );
  }
}

The C standard does not allow void pointer arithmetic. However, GNU C is allowed by considering the size of void is 1.

C11 standard §6.2.5

Paragraph - 19

The void type comprises an empty set of values; it is an incomplete object type that cannot be completed.

Following program is working fine in GCC compiler.

#include<stdio.h>

int main()
{
    int arr[2] = {1, 2};
    void *ptr = &arr;
    ptr = ptr + sizeof(int);
    printf("%d\n", *(int *)ptr);
    return 0;
}

May be other compilers generate an error.
