Mistake in original post is acquire() call set inside the try loop. Here is a correct approach to use "binary" semaphore (Mutex):

semaphore.acquire();
try {
   //do stuff
} catch (Exception e) {
   //exception stuff
} finally {
   semaphore.release();
}

You could also use bc

hour=8
result=$(echo "$hour + 1" | bc)
echo $result

I am assuming an element having an id of btn1 exists in the web page, and also that jQuery is included. This has worked across all modern browsers of Chrome, FireFox, IE >=9 and Edge. jQuery is only being used to determine the position relative to document.

var screenRelativeTop =  $("#btn1").offset().top - (window.scrollY || 
                                            window.pageYOffset || document.body.scrollTop);

var screenRelativeLeft =  $("#btn1").offset().left - (window.scrollX ||
                                           window.pageXOffset || document.body.scrollLeft);

Just to add to @ThijsW's answer, there is a significant speed advantage to the first method over the concatenation method:

big = 1e5;
tic;
x = rand(big,1);
toc

x = zeros(big,1);
tic;
for ii = 1:big
    x(ii) = rand;
end
toc

x = []; 
tic; 
for ii = 1:big
    x(end+1) = rand; 
end; 
toc 

x = []; 
tic; 
for ii = 1:big
    x = [x rand]; 
end; 
toc

   Elapsed time is 0.004611 seconds.
   Elapsed time is 0.016448 seconds.
   Elapsed time is 0.034107 seconds.
   Elapsed time is 12.341434 seconds.

I got these times running in 2012b however when I ran the same code on the same computer in matlab 2010a I get

Elapsed time is 0.003044 seconds.
Elapsed time is 0.009947 seconds.
Elapsed time is 12.013875 seconds.
Elapsed time is 12.165593 seconds.

So I guess the speed advantage only applies to more recent versions of Matlab

If you wish to get JSON object without any extra fields - please add this annotation to your class, it worked perfect for me.

@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})

You can also add in your application.properties file this row, but it will add an extra field to your JSON.

spring.jackson.serialization.FAIL_ON_EMPTY_BEANS=false

Using plain old JavaScript worked for me:
document.querySelector('#elementName').click();

Python if x is not None or if not x is None?

TLDR: The bytecode compiler parses them both to x is not None - so for readability's sake, use if x is not None.

Readability

We use Python because we value things like human readability, useability, and correctness of various paradigms of programming over performance.

Python optimizes for readability, especially in this context.

Parsing and Compiling the Bytecode

The not binds more weakly than is, so there is no logical difference here. See the documentation:

The operators is and is not test for object identity: x is y is true if and only if x and y are the same object. x is not y yields the inverse truth value.

The is not is specifically provided for in the Python grammar as a readability improvement for the language:

comp_op: '<'|'>'|'=='|'>='|'<='|'<>'|'!='|'in'|'not' 'in'|'is'|'is' 'not'

And so it is a unitary element of the grammar as well.

Of course, it is not parsed the same:

>>> import ast
>>> ast.dump(ast.parse('x is not None').body[0].value)
"Compare(left=Name(id='x', ctx=Load()), ops=[IsNot()], comparators=[Name(id='None', ctx=Load())])"
>>> ast.dump(ast.parse('not x is None').body[0].value)
"UnaryOp(op=Not(), operand=Compare(left=Name(id='x', ctx=Load()), ops=[Is()], comparators=[Name(id='None', ctx=Load())]))"

But then the byte compiler will actually translate the not ... is to is not:

>>> import dis
>>> dis.dis(lambda x, y: x is not y)
  1           0 LOAD_FAST                0 (x)
              3 LOAD_FAST                1 (y)
              6 COMPARE_OP               9 (is not)
              9 RETURN_VALUE
>>> dis.dis(lambda x, y: not x is y)
  1           0 LOAD_FAST                0 (x)
              3 LOAD_FAST                1 (y)
              6 COMPARE_OP               9 (is not)
              9 RETURN_VALUE

So for the sake of readability and using the language as it was intended, please use is not.

To not use it is not wise.

Rotate 90 clockwise:

ffmpeg -i in.mov -vf "transpose=1" out.mov

For the transpose parameter you can pass:

0 = 90CounterCLockwise and Vertical Flip (default)
1 = 90Clockwise
2 = 90CounterClockwise
3 = 90Clockwise and Vertical Flip

Use -vf "transpose=2,transpose=2" for 180 degrees.

Make sure you use a recent ffmpeg version from here (a static build will work fine).

Note that this will re-encode the audio and video parts. You can usually copy the audio without touching it, by using -c:a copy. To change the video quality, set the bitrate (for example with -b:v 1M) or have a look at the H.264 encoding guide if you want VBR options.

A solution is also to use this convenience script.

The reason that you get the 404 File Not Found error, is that your path to CSS given as a value to the href attribute is missing context path.

An HTTP request URL contains the following parts:

http://[host]:[port][request-path]?[query-string]

The request path is further composed of the following elements:

• Context path: A concatenation of a forward slash (/) with the context root of the servlet's web application. Example: http://host[:port]/context-root[/url-pattern]

• Servlet path: The path section that corresponds to the component alias that activated this request. This path starts with a forward slash (/).

• Path info: The part of the request path that is not part of the context path or the servlet path.

Read more here.

Solutions

There are several solutions to your problem, here are some of them:

1) Using <c:url> tag from JSTL

In my Java web applications I usually used <c:url> tag from JSTL when defining the path to CSS/JavaScript/image and other static resources. By doing so you can be sure that those resources are referenced always relative to the application context (context path).

If you say, that your CSS is located inside WebContent folder, then this should work:

<link type="text/css" rel="stylesheet" href="<c:url value="/globalCSS.css" />" />

The reason why it works is explained in the "JavaServer Pages™ Standard Tag Library" version 1.2 specification chapter 7.5 (emphasis mine):

7.5 <c:url>
Builds a URL with the proper rewriting rules applied.
...
The URL must be either an absolute URL starting with a scheme (e.g. "http:// server/context/page.jsp") or a relative URL as defined by JSP 1.2 in JSP.2.2.1 "Relative URL Specification". As a consequence, an implementation must prepend the context path to a URL that starts with a slash (e.g. "/page2.jsp") so that such URLs can be properly interpreted by a client browser.

NOTE
Don't forget to use Taglib directive in your JSP to be able to reference JSTL tags. Also see an example JSP page here.

2) Using JSP Expression Language and implicit objects

An alternative solution is using Expression Language (EL) to add application context:

<link type="text/css" rel="stylesheet" href="${pageContext.request.contextPath}/globalCSS.css" />

Here we have retrieved the context path from the request object. And to access the request object we have used the pageContext implicit object.

3) Using <c:set> tag from JSTL

DISCLAIMER
The idea of this solution was taken from here.

To make accessing the context path more compact than in the solution ?2, you can first use the JSTL <c:set> tag, that sets the value of an EL variable or the property of an EL variable in any of the JSP scopes (page, request, session, or application) for later access.

<c:set var="root" value="${pageContext.request.contextPath}"/>
...
<link type="text/css" rel="stylesheet" href="${root}/globalCSS.css" />

IMPORTANT NOTE
By default, in order to set the variable in such manner, the JSP that contains this set tag must be accessed at least once (including in case of setting the value in the application scope using scope attribute, like <c:set var="foo" value="bar" scope="application" />), before using this new variable. For instance, you can have several JSP files where you need this variable. So you must ether a) both set the new variable holding context path in the application scope AND access this JSP first, before using this variable in other JSP files, or b) set this context path holding variable in EVERY JSP file, where you need to access to it.

4) Using ServletContextListener

The more effective way to make accessing the context path more compact is to set a variable that will hold the context path and store it in the application scope using a Listener. This solution is similar to solution ?3, but the benefit is that now the variable holding context path is set right at the start of the web application and is available application wide, no need for additional steps.

We need a class that implements ServletContextListener interface. Here is an example of such class:

package com.example.listener;

import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.annotation.WebListener;

@WebListener
public class AppContextListener implements ServletContextListener {

    @Override
    public void contextInitialized(ServletContextEvent event) {
        ServletContext sc = event.getServletContext();
        sc.setAttribute("ctx", sc.getContextPath());
    }

    @Override
    public void contextDestroyed(ServletContextEvent event) {}

}

Now in a JSP we can access this global variable using EL:

<link type="text/css" rel="stylesheet" href="${ctx}/globalCSS.css" />

NOTE
@WebListener annotation is available since Servlet version 3.0. If you use a servlet container or application server that supports older Servlet specifications, remove the @WebServlet annotation and instead configure the listener in the deployment descriptor (web.xml). Here is an example of web.xml file for the container that supports maximum Servlet version 2.5 (other configurations are omitted for the sake of brevity):

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                        http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    version="2.5">
    ...  
    <listener>
        <listener-class>com.example.listener.AppContextListener</listener-class>
    </listener>
    ...
</webapp>

5) Using scriptlets

As suggested by user @gavenkoa you can also use scriptlets like this:

<%= request.getContextPath() %>

For such a small thing it is probably OK, just note that generally the use of scriptlets in JSP is discouraged.

Conclusion

I personally prefer either the first solution (used it in my previous projects most of the time) or the second, as they are most clear, intuitive and unambiguous (IMHO). But you choose whatever suits you most.

Other thoughts

You can deploy your web app as the default application (i.e. in the default root context), so it can be accessed without specifying context path. For more info read the "Update" section here.

One of #a or #b needs to be not position:absolute, so that #box will grow to accommodate it.

So you can stop #a from being position:absolute, and still position #b over the top of it, like this:

 #box {_x000D_
        background-color: #000;_x000D_
        position: relative;     _x000D_
        padding: 10px;_x000D_
        width: 220px;_x000D_
    }_x000D_
    _x000D_
    .a {_x000D_
        width: 210px;_x000D_
        background-color: #fff;_x000D_
        padding: 5px;_x000D_
    }_x000D_
    _x000D_
    .b {_x000D_
        width: 100px; /* So you can see the other one */_x000D_
        position: absolute;_x000D_
        top: 10px; left: 10px;_x000D_
        background-color: red;_x000D_
        padding: 5px;_x000D_
    }_x000D_
    _x000D_
    #after {_x000D_
        background-color: yellow;_x000D_
        padding: 10px;_x000D_
        width: 220px;_x000D_
    }

    <div id="box">_x000D_
        <div class="a">Lorem</div>_x000D_
        <div class="b">Lorem</div>_x000D_
    </div>_x000D_
    <div id="after">Hello world</div>

(Note that I've made the widths different, so you can see one behind the other.)

Edit after Justine's comment: Then your only option is to specify the height of #box. This:

#box {
    /* ... */
    height: 30px;
}

works perfectly, assuming the heights of a and b are fixed. Note that you'll need to put IE into standards mode by adding a doctype at the top of your HTML

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
          "http://www.w3.org/TR/html4/strict.dtd">

before that works properly.

You're thinking too complicated. It's actually just $('#'+openaddress).

PHP has a method called md5 ;-) Just $password = md5($passToEncrypt);

If you are searching in a SQL u can use a MySQL Method MD5() too....

 SELECT * FROM user WHERE Password='. md5($password) .'

or SELECT * FROM ser WHERE Password=MD5('. $password .')

To insert it u can do it the same way.

May I suggest the concept of Duck-typing?

Most likely you would tend to make the Pegasus extend a Bird and a Horse interface but duck typing actually suggests that you should rather inherit behaviour. As already stated in the comments, a pegasus is not a bird but it can fly. So your Pegasus should rather inherit a Flyable-interface and lets say a Gallopable-interface.

This kind of concept is utilized in the Strategy Pattern. The given example actually shows you how a duck inherits the FlyBehaviour and QuackBehaviour and still there can be ducks, e.g. the RubberDuck, which can't fly. They could have also made the Duck extend a Bird-class but then they would have given up some flexibility, because every Duck would be able to fly, even the poor RubberDuck.

Use anchors.

Main Page:

<a href="/sample#sushi">Sushi</a>
<a href="/sample#bBQ">BBQ</a>

Sample Page:

<div id='sushi'><a name="sushi"></a></div>
<div id='bbq'><a name="bbq"></a></div>

This actually worked for me

    Spinner spinner = new Spinner(this);
    ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(
            this, android.R.layout.simple_spinner_item, spinnerArray);
    spinnerArrayAdapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item );

    spinner = (Spinner) findViewById( R.id.spinner );
    spinner.setAdapter(spinnerArrayAdapter);

I wrestled quite a while with the proper syntax for CREATE TEMPORARY TABLE SELECT. Having figured out a few things, I wanted to share the answers with the rest of the community.

Basic information about the statement is available at the following MySQL links:

CREATE TABLE SELECT and CREATE TABLE.

At times it can be daunting to interpret the spec. Since most people learn best from examples, I will share how I have created a working statement, and how you can modify it to work for you.

1. Add multiple indexes

   This statement shows how to add multiple indexes (note that index names - in lower case - are optional):

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (INDEX my_index_name (tag, time), UNIQUE my_unique_index_name (order_number))
   SELECT * FROM core.my_big_table
   WHERE my_val = 1
   

2. Add a new primary key:

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (PRIMARY KEY my_pkey (order_number),
   INDEX cmpd_key (user_id, time))
   SELECT * FROM core.my_big_table
   

3. Create additional columns

   You can create a new table with more columns than are specified in the SELECT statement. Specify the additional column in the table definition. Columns specified in the table definition and not found in select will be first columns in the new table, followed by the columns inserted by the SELECT statement.

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (my_new_id BIGINT NOT NULL AUTO_INCREMENT,  
   PRIMARY KEY my_pkey (my_new_id), INDEX my_unique_index_name (invoice_number))
   SELECT * FROM core.my_big_table
   

4. Redefining data types for the columns from SELECT

   You can redefine the data type of a column being SELECTed. In the example below, column tag is a MEDIUMINT in core.my_big_table and I am redefining it to a BIGINT in core.my_tmp_table.

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (tag BIGINT,
   my_time DATETIME,  
   INDEX my_unique_index_name (tag) )
   SELECT * FROM core.my_big_table
   

5. Advanced field definitions during create

   All the usual column definitions are available as when you create a normal table. Example:

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
   value BIGINT UNSIGNED NOT NULL DEFAULT 0 UNIQUE,
   location VARCHAR(20) DEFAULT "NEEDS TO BE SET",
   country CHAR(2) DEFAULT "XX" COMMENT "Two-letter country code",  
   INDEX my_index_name (location))
   ENGINE=MyISAM 
   SELECT * FROM core.my_big_table
   

You can design a lowpass Butterworth filter in runtime, using butter() function, and then apply that to the signal.

fc = 300; % Cut off frequency
fs = 1000; % Sampling rate

[b,a] = butter(6,fc/(fs/2)); % Butterworth filter of order 6
x = filter(b,a,signal); % Will be the filtered signal

Highpass and bandpass filters are also possible with this method. See https://www.mathworks.com/help/signal/ref/butter.html

The first parentheses are for, if you will, order of operations. The 'result' of the set of parentheses surrounding the function definition is the function itself which, indeed, the second set of parentheses executes.

As to why it's useful, I'm not enough of a JavaScript wizard to have any idea. :P

Depends what it is that you're trying to do it with. You could use something like this:

echo "<a href=\"javascript:history.go(-1)\">GO BACK</a>";

That's the simplest option. The other poster is right about having a proper flow of history but this is an example for you.

Just edited, orig version wasn't indented and looked like nothing. ;)

I had this problem with a third party code. Someone forgot to set the super inside of viewWillAppear and viewWillDisappear in a custom TabBarController class.

- (void) viewWillAppear:(BOOL)animated {

    [super viewWillAppear:animated];
    // code...
}

or

- (void) viewWillDisappear:(BOOL)animated {

    [super viewWillDisappear:animated];
    // code...
}

Spent hours trying to fix the error for importing local modules. Code execution was fine but pylint showed:

    Unable to import '<module>'

Finally figured:

1. First of all, select the correct python path. (In the case of a virtual environment, it will be venv/bin/python). You can do this by hitting

2. Make sure that your pylint path is the same as the python path you chose in step 1. (You can open VS Code from within the activated venv from terminal so it automatically performs these two steps)

3. The most important step: Add an empty __init__.py file in the folder that contains your module file. Although python3 does not require this file for importing modules, I think pylint still requires it for linting.

Restart VS Code, the errors should be gone!

I tried all existing fixes and not working for me

I re-install python 2.7 (will also install pip) by downloading .pkg at https://www.python.org/downloads/mac-osx/

works for me after installation downloaded pkg

To plot an equation that is not solved for a specific variable (like circle or hyperbola):

import numpy as np  
import matplotlib.pyplot as plt  
plt.figure() # Create a new figure window
xlist = np.linspace(-2.0, 2.0, 100) # Create 1-D arrays for x,y dimensions
ylist = np.linspace(-2.0, 2.0, 100) 
X,Y = np.meshgrid(xlist, ylist) # Create 2-D grid xlist,ylist values
F = X**2 + Y**2 - 1  #  'Circle Equation
plt.contour(X, Y, F, [0], colors = 'k', linestyles = 'solid')
plt.show()

Specifically, this is not rounding your result, it's truncating toward zero. So if you divide -3/2, you'll get -1 and not -2. Welcome to integral math! Back before CPUs could do floating point operations or the advent of math co-processors, we did everything with integral math. Even though there were libraries for floating point math, they were too expensive (in CPU instructions) for general purpose, so we used a 16 bit value for the whole portion of a number and another 16 value for the fraction.

EDIT: my answer makes me think of the classic old man saying "when I was your age..."

If the variable table contains invalid characters (like a space) you should add square brackets around the variable.

public DataTable fillDataTable(string table)
{
    string query = "SELECT * FROM dstut.dbo.[" + table + "]";

    using(SqlConnection sqlConn = new SqlConnection(conSTR))
    using(SqlCommand cmd = new SqlCommand(query, sqlConn))
    {
        sqlConn.Open();
        DataTable dt = new DataTable();
        dt.Load(cmd.ExecuteReader());
        return dt;
    }
}

By the way, be very careful with this kind of code because is open to Sql Injection. I hope for you that the table name doesn't come from user input

I agree - it's probably safer to use a GET request if you're just passing data in the URL and not in the body. See this similar question for some additional views on the whole POST+GET concept.

As said by Sparky in comments on many answers to this question, there is NOT any textarea value for the type attribute of the input tag.

On other terms, the following markup is not valid :

<input type="textarea" />

And the browser replaces it by the default :

<input type="text" />

To define a multi-lines text input, use :

<textarea></textarea>

See the textarea element documentation for more details.

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

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

There are several tools which can import Excel to SQL Server.

I am using DbTransfer (http://www.dbtransfer.com/Products/DbTransfer) to do the job. It's primarily focused on transfering data between databases and excel, xml, etc...

I have tried the openrowset method and the SQL Server Import / Export Assitant before. But I found these methods to be unnecessary complicated and error prone in constrast to doing it with one of the available dedicated tools.

I solved it in my site making this in functions.php

add_action("template_redirect", "start_buffer");
add_action("shutdown", "end_buffer", 999);

function filter_buffer($buffer) {
    $buffer = replace_insecure_links($buffer);
    return $buffer;
}
function start_buffer(){
    ob_start("filter_buffer");
}

function end_buffer(){
    if (ob_get_length()) ob_end_flush();
}

function replace_insecure_links($str) {

   $str = str_replace ( array("http://www.yoursite.com/", "https://www.yoursite.com/") , array("/", "/"), $str);

   return apply_filters("rsssl_fixer_output", $str);

}

I took part of one plugin, cut it into pieces and make this. It replaced ALL links in my site (menus, css, scripts etc.) and everything was working.

You can do this too:

oldIFS="$IFS"
IFS=$'\n' arr=($(<file))
IFS="$oldIFS"
echo "${arr[1]}" # It will print `A Dog`.

Note:

Filename expansion still occurs. For example, if there's a line with a literal * it will expand to all the files in current folder. So use it only if your file is free of this kind of scenario.

1) Also you can use lateinit If you sure do your initialization later on onCreate() or elsewhere.

Use this

lateinit var left: Node

Instead of this

var left: Node? = null

2) And there is other way that use !! end of variable when you use it like this

queue.add(left!!) // add !!

You should use raw_input because you are using python-2.7. When you use input() on a variable (for example: s = input('Name: ')), it will execute the command ON the Python environment without saving what you wrote on the variable (s) and create an error if what you wrote is not defined.

raw_input() will save correctly what you wrote on the variable (for example: f = raw_input('Name : ')), and it will not execute it in the Python environment without creating any possible error:

input_variable = raw_input('Enter Your Name : ')
print("Your Name Is  : " + (input_variable))

Assuming by "special" you mean non-word characters, then that is pretty easy.

str = str.replace(/[_\W]+/g, "-")

you can just do $scope.todo = Todo.get({ id: 123 }). .get() and .query() on a Resource return an object immediately and fill it with the result of the promise later (to update your template). It's not a typical promise which is why you need to either use a callback or the $promise property if you have some special code you want executed after the call. But there is no need to assign it to your scope in a callback if you are only using it in the template.

Please go to this quick example I've created jsFiddle. Hopefull it's easy to understand. You can use a wrapper div with the width of the site to center align. The reason you must put width is that so browser knows you are not going for a liquid layout.

The solution is not good, even you fixed your naming and unreachable statement of that print out.

things you should pay attention also 1. randomness seed, and large data, will num of item is so big returned num of that random < itemlist.size().

1. you didn't handle multithread, you might get index out of bound exception

Your expression works if you add parentheses:

>>> y[(1 < x) & (x < 5)]
array(['o', 'o', 'a'], 
      dtype='|S1')

My best solution (so far) for calculating the number of days difference:

//  This assumes that you already have two Date objects: startDate, endDate
//  Also, that you want to ignore any time portions

Calendar startCale=new GregorianCalendar();
Calendar endCal=new GregorianCalendar();

startCal.setTime(startDate);
endCal.setTime(endDate);

endCal.add(Calendar.YEAR,-startCal.get(Calendar.YEAR));
endCal.add(Calendar.MONTH,-startCal.get(Calendar.MONTH));
endCal.add(Calendar.DATE,-startCal.get(Calendar.DATE));

int daysDifference=endCal.get(Calendar.DAY_OF_YEAR);

Note, however, that this assumes less than a year's difference!

Try the below query

CREATE TABLE card_types (

With BeautifulStoneSoup gone in bs4, it's even simpler in Python3

from bs4 import BeautifulSoup

soup = BeautifulSoup(html)
text = soup.get_text()
print(text)

It just specifies what interpreter you want to use. To understand this, create a file through terminal by doing touch test.py, then type into that file the following:

#!/usr/bin/env python3
print "test"

and do chmod +x test.py to make your script executable. After this when you do ./test.py you should get an error saying:

  File "./test.py", line 2
    print "test"
               ^
SyntaxError: Missing parentheses in call to 'print'

because python3 doesn't supprt the print operator.

Now go ahead and change the first line of your code to:

#!/usr/bin/env python2

and it'll work, printing test to stdout, because python2 supports the print operator. So, now you've learned how to switch between script interpreters.

May be your dump.sql is having garbage character in beginning of your file or there is a blank line in beginning.

I found this extension for VS code called Git Merger. It adds Git: Merge from to the commands.

You have to import the following two libraries:

import java.util.*
import kotlin.concurrent.schedule

and after that use it in this way:

Timer().schedule(10000){
    //do something
}

Change your Ands to AndAlsos

A standard And will test both expressions. If comp.Container is Nothing, then the second expression will raise a NullReferenceException because you're accessing a property on a null object.

AndAlso will short-circuit the logical evaluation. If comp.Container is Nothing, then the 2nd expression will not be evaluated.

Just don't perform e.preventDefault();, or perform it conditionally.

You certainly can't alter when the original event action occurs.

If you want to "recreate" the original UI event some time later (say, in the callback for an AJAX request) then you'll just have to fake it some other way (like in vzwick's answer)... though I'd question the usability of such an approach.

If you have multiple subplots, i.e.

fig, ax = plt.subplots(4, 2)

You can use the same y limits for all of them. It gets limits of y ax from first plot.

plt.setp(ax, ylim=ax[0,0].get_ylim())

int is predefined in library function c# but in java we can create object of Integer

When you try to connect your remote server with ssh:

$ ssh username@ip_address

then the error raise, to solve it:

$ ssh-keygen -f "/home/local_username/.ssh/known_hosts" -R "ip_address"

To increase the amount of memory allocated to R you can use memory.limit

memory.limit(size = ...)

Or

memory.size(max = ...)

About the arguments

• size - numeric. If NA report the memory limit, otherwise request a new limit, in Mb. Only values of up to 4095 are allowed on 32-bit R builds, but see ‘Details’.
• max - logical. If TRUE the maximum amount of memory obtained from the OS is reported, if FALSE the amount currently in use, if NA the memory limit.

The updatePolicy tag didn't work for me. However Rich Seller mentioned that snapshots should be disabled anyways so I looked further and noticed that the extra repository that I added to my settings.xml was causing the problem actually. Adding the snapshots section to this repository in my settings.xml did the trick!

<repository>
    <id>jboss</id>
    <name>JBoss Repository</name>
    <url>http://repository.jboss.com/maven2</url>
    <snapshots>
        <enabled>false</enabled>
    </snapshots>
</repository>

Now, it's easy to do it by enabling/disabling cache option in your ajax request, just like this

$(function () {
    var url = 'your url goes here';
    $('#ajaxButton').click(function (e) {
        $.ajax({
            url: url,
            data: {
                test: 'value'
            },
                cache: true, //cache enabled, false to reverse
                complete: doSomething
            });
        });
    });
    //ToDo after ajax call finishes
    function doSomething(data) {
        console.log(data);
    }
});

This data is JSON! You can deserialize it using the built-in json module if you're on Python 2.6+, otherwise you can use the excellent third-party simplejson module.

import json    # or `import simplejson as json` if on Python < 2.6

json_string = u'{ "id":"123456789", ... }'
obj = json.loads(json_string)    # obj now contains a dict of the data

Yes, in principe it is possible, but it doesn't come for free.

You need to create a StackTrace, and then you can have a look at the StackFrame's of the call stack.

The error is indeed fixed by inserting this with a type annotation as the first callback parameter. My attempt to do that was botched by simultaneously changing the callback into an arrow-function:

foo.on('error', (this: Foo, err: any) => { // DON'T DO THIS

It should've been this:

foo.on('error', function(this: Foo, err: any) {

or this:

foo.on('error', function(this: typeof foo, err: any) {

A GitHub issue was created to improve the compiler's error message and highlight the actual grammar error with this and arrow-functions.

All do not work for me on eloquent collections, laravel eloquent collections use the key from the items I think which causes merging issues, you need to get the first collection back as an array, put that into a fresh collection and then push the others into the new collection;

public function getFixturesAttribute()
{
    $fixtures = collect( $this->homeFixtures->all() );
    $this->awayFixtures->each( function( $fixture ) use ( $fixtures ) {
        $fixtures->push( $fixture );
    });
    return $fixtures;
}

overflow-x: hidden;
would hide any thing on the x-axis that goes outside of the element, so there would be no need for the horizontal scrollbar and it get removed.

overflow-y: hidden;
would hide any thing on the y-axis that goes outside of the element, so there would be no need for the vertical scrollbar and it get removed.

overflow: hidden;
would remove both scrollbars

You can have a look at dozer which is a

Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types.

Another better link...

Since http proxy protocol is similar to raw http protocol, you can redirect desired traffic to your development server by telling firefox it's a proxy server.

two limitations:

A. this won't let you use https connections.

B. some frameworks (e,g: wordpress) don't like this method and redirect the request the wrong way

just copy the following code into a .pac file (enter your site domain and IP address, of course), and switch development/production just by changing proxy configuration.

function FindProxyForURL(url, host) {
    var prox4site = {
        "mysite.com":"PROXY 10.0.1.100:80",
        "www.mysite.com":"PROXY 10.0.1.100:80"
    }

    return prox4site[host] || "DIRECT";
}

I noticed that invalid syntax error for no apparent reason can be caused by using space in:

print(f'{something something}')

Python IDLE seems to jump and highlight a part of the first line for some reason (even if the first line happens to be a comment), which is misleading.

Your schema is for its target namespace http://www.example.org/Test so it defines an element with name MyElement in that target namespace http://www.example.org/Test. Your instance document however has an element with name MyElement in no namespace. That is why the validating parser tells you it can't find a declaration for that element, you haven't provided a schema for elements in no namespace.

You either need to change the schema to not use a target namespace at all or you need to change the instance to use e.g. <MyElement xmlns="http://www.example.org/Test">A</MyElement>.

Your problem comes from the 32/64 bit version of your JDK/JRE... Your shared lib is searched for a 32 bit version.

Your default JDK is a 32 bit version. Try to install a 64 bit one by default and relaunch your `.sh file.

In my case, I ran into this error this way. pom.xml of my project defined two dependencies A and B. And both A and B defined dependency on same artifact (call it C) but different versions of it (C.1 and C.2). When this happens, for each class in C maven can only select one version of the class from the two versions (while building an uber-jar). It will select the "nearest" version based on its dependency mediation rules and will output a warning "We have a duplicate class..." If a method/class signature changes between the versions, it can cause a java.lang.IncompatibleClassChangeError exception if the incorrect version is used at runtime.

Advanced: If A must use v1 of C and B must use v2 of C, then we must relocate C in A and B's poms to avoid class conflict (we have a duplicate class warning) when building the final project that depends on both A and B.

On base this answer from Hiery Nomus.

You can create a branch as an orphan:

git checkout --orphan <branchname>

This will create a new branch with no parents. Then, you can clear the working directory with:

git rm --cached -r .

And then you just commit branch with empty commit and then push

git commit -m <commit message> --allow-empty
git push origin <newbranch>

You can try FileUtils from org.apache.commons.io.FileUtils, try downloading jar from here

and you can use the following method: FileUtils.readFileToString("yourFileName");

Hope it helps you..

This helped me: just wait about a minute or two.

Wait a few minutes, then retry your operation.

I know this is a rather old question as of now, but I had found the proper solution was that I was not declaring the assembly attribute.

My code is:

using AutoMapper;
...

namespace [...].Controllers
{
    public class HousingTenureTypesController : LookupController<HousingTenureType, LookupTypeModel>
    {
        Mapper.CreateMap<HousingTenureType, LookupTypeModel>().ReverseMap();
    }
    ...
}

This was fixed by adding the following line before my namespace declaration:

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(HousingTenureTypesController), "AutoMapperStart")]

The full code is:

using AutoMapper;
...

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(HousingTenureTypesController), "AutoMapperStart")]

namespace [...].Controllers
{
    public class HousingTenureTypesController : LookupController<HousingTenureType, LookupTypeModel>
    {
        Mapper.CreateMap<HousingTenureType, LookupTypeModel>().ReverseMap();
    }
    ...
}

I couldn't get live or delegate to work on a div in a lightbox (tinybox).

I used setTimeout successfullly, in the following simple way:

$('#displayContact').click(function() {
    TINY.box.show({html:'<form><textarea id="contactText"></textarea><div id="contactSubmit">Submit</div></form>', close:true});
    setTimeout(setContactClick, 1000);
})

function setContactClick() {
    $('#contactSubmit').click(function() {
        alert($('#contactText').val());
    })
}

You have two choices:

1. Use fileno() to obtain the file descriptor associated with the stdio stream pointer

2. Don't use <stdio.h> at all, that way you don't need to worry about flush either - all writes will go to the device immediately, and for character devices the write() call won't even return until the lower-level IO has completed (in theory).

For device-level IO I'd say it's pretty unusual to use stdio. I'd strongly recommend using the lower-level open(), read() and write() functions instead (based on your later reply):

int fd = open("/dev/i2c", O_RDWR);
ioctl(fd, IOCTL_COMMAND, args);
write(fd, buf, length);

Try this all four way to take input with space :)

#include<iostream>
#include<stdio.h>

using namespace std;

void dinput(char *a)
{
    for(int i=0;; i++)
    {
        cin >> noskipws >> a[i];
        if(a[i]=='\n')
        {
            a[i]='\0';
            break;
        }
    }
}


void input(char *a)
{
    //cout<<"\nInput string: ";

    for(int i=0;; i++)
    {
        *(a+i*sizeof(char))=getchar();

        if(*(a+i*sizeof(char))=='\n')
        {
            *(a+i*sizeof(char))='\0';
            break;
        }

    }
}



int main()
{
    char a[20];

    cout<<"\n1st method\n";
    input(a);
    cout<<a;

    cout<<"\n2nd method\n";
    cin.get(a,10);
    cout<<a;

    cout<<"\n3rd method\n";
    cin.sync();
    cin.getline(a,sizeof(a));
    cout<<a;

    cout<<"\n4th method\n";
    dinput(a);
    cout<<a;

    return 0;
}

Watch out: if you're generating the random inside a loop like for example for(int i = 0; i < 10; i++), do not put the new Random() declaration inside the loop.

From MSDN:

The random number generation starts from a seed value. If the same seed is used repeatedly, the same series of numbers is generated. One way to produce different sequences is to make the seed value time-dependent, thereby producing a different series with each new instance of Random. By default, the parameterless constructor of the Random class uses the system clock to generate its seed value...

So based on this fact, do something as:

var random = new Random();

for(int d = 0; d < 7; d++)
{
    // Actual BOE
    boes.Add(new LogBOEViewModel()
    {
        LogDate = criteriaDate,
        BOEActual = GetRandomDouble(random, 100, 1000),
        BOEForecast = GetRandomDouble(random, 100, 1000)
    });
}

double GetRandomDouble(Random random, double min, double max)
{
     return min + (random.NextDouble() * (max - min));
}

Doing this way you have the guarantee you'll get different double values.

An example of a simple validator in Python3 using the popular library lxml

Installation lxml

pip install lxml

If you get an error like "Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?", try to do this first:

# Debian/Ubuntu
apt-get install python-dev python3-dev libxml2-dev libxslt-dev

# Fedora 23+
dnf install python-devel python3-devel libxml2-devel libxslt-devel

The simplest validator

Let's create simplest validator.py

from lxml import etree

def validate(xml_path: str, xsd_path: str) -> bool:

    xmlschema_doc = etree.parse(xsd_path)
    xmlschema = etree.XMLSchema(xmlschema_doc)

    xml_doc = etree.parse(xml_path)
    result = xmlschema.validate(xml_doc)

    return result

then write and run main.py

from validator import validate

if validate("path/to/file.xml", "path/to/scheme.xsd"):
    print('Valid! :)')
else:
    print('Not valid! :(')

A little bit of OOP

In order to validate more than one file, there is no need to create an XMLSchema object every time, therefore:

validator.py

from lxml import etree

class Validator:

    def __init__(self, xsd_path: str):
        xmlschema_doc = etree.parse(xsd_path)
        self.xmlschema = etree.XMLSchema(xmlschema_doc)

    def validate(self, xml_path: str) -> bool:
        xml_doc = etree.parse(xml_path)
        result = self.xmlschema.validate(xml_doc)

        return result

Now we can validate all files in the directory as follows:

main.py

import os
from validator import Validator

validator = Validator("path/to/scheme.xsd")

# The directory with XML files
XML_DIR = "path/to/directory"

for file_name in os.listdir(XML_DIR):
    print('{}: '.format(file_name), end='')

    file_path = '{}/{}'.format(XML_DIR, file_name)

    if validator.validate(file_path):
        print('Valid! :)')
    else:
        print('Not valid! :(')

Well, since neither of the given replies helped me, I had to look more, and found solution in this article.

And the answer in a nutshell is the following:

Connecting to MySQL using MySQL Workbench

Connection Method: Standard TCP/IP over SSH
SSH Hostname: <Local VM IP Address (set in PuPHPet)>
SSH Username: vagrant (the default username)
SSH Password: vagrant (the default password)
MySQL Hostname: 127.0.0.1
MySQL Server Port: 3306
Username: root
Password: <MySQL Root Password (set in PuPHPet)>

Using given approach I was able to connect to mysql database in vagrant from host Ubuntu machine using MySQL Workbench and also using Valentina Studio.

A small note about the efficiency of abovementioned methods:

 library(microbenchmark)

  microbenchmark(
    which("Feb" == month.abb)[[1]],
    which(month.abb %in% "Feb"))

  Unit: nanoseconds
   min     lq    mean median     uq  max neval
   891  979.0 1098.00   1031 1135.5 3693   100
   1052 1175.5 1339.74   1235 1390.0 7399  100

So, the best one is

    which("Feb" == month.abb)[[1]]

I went threw the same problem. None of the answers above worked for me, but i ended finding the solution on my own. The ipa file wasn't created because there was library files (libXXX.a) in Target-> Build Phases -> Copy Bundle with resources

Hope it will help someone :)

If your application is making heavy use of Date and Calendar objects, you really should use Joda Time, because java.util.Date is mutable. java.util.Calendar has performance problems when its fields get updated, and is clunky for datetime arithmetic.

This best for XML Deserialize

 public static object Deserialize(string xml, Type toType)
    {

        using (MemoryStream memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(xml)))
        {
            System.IO.StreamReader str = new System.IO.StreamReader(memoryStream);
            System.Xml.Serialization.XmlSerializer xSerializer = new System.Xml.Serialization.XmlSerializer(toType);
            return xSerializer.Deserialize(str);
        }

    }

<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    //more views

</androidx.constraintlayout.widget.ConstraintLayout>

In the above code, the basic need of tools:context is to tell which activity or fragment the layout file is associated with by default. So, you can specify the activity class name using the same dot prefix as used in Manifest file.

By doing so, the Android Studio will choose the necessary theme for the preview automatically and you don’t have to do the preview settings manually. As we all know that a layout file can be associated with several activities but the themes are defined in the Manifest file and these themes are associated with your activity. So, by adding tools:context in your layout file, the Android Studio preview will automatically choose the necessary theme for you.

In your androidmanifest.xml file:

   <activity android:name="MainActivity" android:configChanges="keyboardHidden|orientation">

or

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

It is a combination of

• Ticking the "Enable annotation processing" checkbox in Settings->Compiler->Annotation Processors.

  and

• Install the plugin of Lombok for idea and restart for change to take effect.

What no-one seems to realize is that none of the System.Uri constructors correctly handles certain paths with percent signs in them.

new Uri(@"C:\%51.txt").AbsoluteUri;

This gives you "file:///C:/Q.txt" instead of "file:///C:/%2551.txt".

Neither values of the deprecated dontEscape argument makes any difference, and specifying the UriKind gives the same result too. Trying with the UriBuilder doesn't help either:

new UriBuilder() { Scheme = Uri.UriSchemeFile, Host = "", Path = @"C:\%51.txt" }.Uri.AbsoluteUri

This returns "file:///C:/Q.txt" as well.

As far as I can tell the framework is actually lacking any way of doing this correctly.

We can try to it by replacing the backslashes with forward slashes and feed the path to Uri.EscapeUriString - i.e.

new Uri(Uri.EscapeUriString(filePath.Replace(Path.DirectorySeparatorChar, '/'))).AbsoluteUri

This seems to work at first, but if you give it the path C:\a b.txt then you end up with file:///C:/a%2520b.txt instead of file:///C:/a%20b.txt - somehow it decides that some sequences should be decoded but not others. Now we could just prefix with "file:///" ourselves, however this fails to take UNC paths like \\remote\share\foo.txt into account - what seems to be generally accepted on Windows is to turn them into pseudo-urls of the form file://remote/share/foo.txt, so we should take that into account as well.

EscapeUriString also has the problem that it does not escape the '#' character. It would seem at this point that we have no other choice but making our own method from scratch. So this is what I suggest:

public static string FilePathToFileUrl(string filePath)
{
  StringBuilder uri = new StringBuilder();
  foreach (char v in filePath)
  {
    if ((v >= 'a' && v <= 'z') || (v >= 'A' && v <= 'Z') || (v >= '0' && v <= '9') ||
      v == '+' || v == '/' || v == ':' || v == '.' || v == '-' || v == '_' || v == '~' ||
      v > '\xFF')
    {
      uri.Append(v);
    }
    else if (v == Path.DirectorySeparatorChar || v == Path.AltDirectorySeparatorChar)
    {
      uri.Append('/');
    }
    else
    {
      uri.Append(String.Format("%{0:X2}", (int)v));
    }
  }
  if (uri.Length >= 2 && uri[0] == '/' && uri[1] == '/') // UNC path
    uri.Insert(0, "file:");
  else
    uri.Insert(0, "file:///");
  return uri.ToString();
}

This intentionally leaves + and : unencoded as that seems to be how it's usually done on Windows. It also only encodes latin1 as Internet Explorer can't understand unicode characters in file urls if they are encoded.

Maybe this one can help:

 el.focus();_x000D_
 return el==document.activeElement;_x000D_
}

Based on what @jjnguy said, and fixing the bug in his PrintAllNodes(), here's the full Console App example:

public class Node

In my situation, it was Application Pool. It is set to restart when idle for xx mins. When I set it to not restart, it seems to use value from Web Config.

You can use modify:

ALTER TABLE `table name` 
modify COLUMN `column name` varchar("length");

This is a very interesting bug. (In my opinion, it is a bug anyway) Nice find!

Regarding how to set it, I would recommend Camilo Martin's answer. But as to why, I'd like to explain this a bit if you guys don't mind.

In the CSS specs I found:

'padding'
Percentages: refer to width of containing block

… which is weird, but okay.

So, with a parent width: 210px and a child padding-top: 50%, I get a calculated/computed value of padding-top: 96.5px – which is not the expected 105px.

That is because in Windows (I'm not sure about other OSs), the size of common scrollbars is per default 17px × 100% (or 100% × 17px for horizontal bars). Those 17px are substracted before calculating the 50%, hence 50% of 193px = 96.5px.

Slightly off-topic, but I found this too useful not to be mentioned here.

What if we would like to read the the Html text from string.xml resource and thus make it easy to localize. CDATA make this possible:

<string name="my_text">
  <![CDATA[
    <b>Autor:</b> Mr Nice Guy<br/>
    <b>Contact:</b> [email protected]<br/>
    <i>Copyright © 2011-2012 Intergalactic Spacebar Confederation </i>
  ]]>
</string> 

From our Java code we could now utilize it like this:

TextView tv = (TextView) findViewById(R.id.myTextView);
tv.setText(Html.fromHtml(getString(R.string.my_text))); 

I did not expect this to work. But it did.

Hope it's useful to some of you!

Change

  #import "RCTBridgeModule.h"

to

As others have pointed out, accessing dicts in Python is fast. They are probably the best-oiled data structure in the language, given their central role. The problem lies elsewhere.

How many tuples are you memoizing? Have you considered the memory footprint? Perhaps you are spending all your time in the memory allocator or paging memory.

A very quick way to solve this as at November 2020 is by the following steps

1. hit the shift key twice, a pop up will show search for a file named "settings.gradle" when it opens change the rootProject.name = "Old-name" to rootProject.name = "new name" then sync.

2. hit the shift key twice, a pop up will show search for a file named "string.xml", when it opens change <string "app_name">old-name to <string "app_name">new-name

3. close android studio

4. locate androidStudioProject directory on your machine, open it and find the project by its old name, rename it to the new name.

5. open Android Studio goto File > Open > "new name". open it from there.

this is currently working on Android Studio 4.1.1

It's usually in the folder specified below, but ProgramData is usually a hidden folder. To show it, go to control panel search for "folder" then under advanced settings tick show hidden files and click apply. C:/ProgramData/MySQL/MySQL Server 5.5/Data/

close the command prompt (cmd) then use text editor terminal or use only cmd to run commands.

in my case this is the problem and how i solved it.

most of the time you are created angular app using command prompt. then you trying to run the app terminal in inside of the text editor. whenever you trying to save you can see some stuff running on the windows command prompt. so just close it and run the command in the terminal of the text editor.

>>> [int(i) for i in str(12345)]

[1, 2, 3, 4, 5]

Another way of returning all files in subdirectories is to use the pathlib module, introduced in Python 3.4, which provides an object oriented approach to handling filesystem paths (Pathlib is also available on Python 2.7 via the pathlib2 module on PyPi):

from pathlib import Path

rootdir = Path('C:/Users/sid/Desktop/test')
# Return a list of regular files only, not directories
file_list = [f for f in rootdir.glob('**/*') if f.is_file()]

# For absolute paths instead of relative the current dir
file_list = [f for f in rootdir.resolve().glob('**/*') if f.is_file()]

Since Python 3.5, the glob module also supports recursive file finding:

import os
from glob import iglob

rootdir_glob = 'C:/Users/sid/Desktop/test/**/*' # Note the added asterisks
# This will return absolute paths
file_list = [f for f in iglob(rootdir_glob, recursive=True) if os.path.isfile(f)]

The file_list from either of the above approaches can be iterated over without the need for a nested loop:

for f in file_list:
    print(f) # Replace with desired operations

I had to rm -rf ./vendor then run bundle install again.

I had the same problem and I solved by using the postcast server. You can install it locally and use it.

Yes, don't Test private methods.... The idea of a unit test is to test the unit by its public 'API'.

If you are finding you need to test a lot of private behavior, most likely you have a new 'class' hiding within the class you are trying to test, extract it and test it by its public interface.

One piece of advice / Thinking tool..... There is an idea that no method should ever be private. Meaning all methods should live on a public interface of an object.... if you feel you need to make it private, it most likely lives on another object.

This piece of advice doesn't quite work out in practice, but its mostly good advice, and often it will push people to decompose their objects into smaller objects.

Just add || true after the command where you want to ignore the error.

You can also write:

[e] * n

You should note that if e is for example an empty list you get a list with n references to the same list, not n independent empty lists.

Performance testing

At first glance it seems that repeat is the fastest way to create a list with n identical elements:

>>> timeit.timeit('itertools.repeat(0, 10)', 'import itertools', number = 1000000)
0.37095273281943264
>>> timeit.timeit('[0] * 10', 'import itertools', number = 1000000)
0.5577236771712819

But wait - it's not a fair test...

>>> itertools.repeat(0, 10)
repeat(0, 10)  # Not a list!!!

The function itertools.repeat doesn't actually create the list, it just creates an object that can be used to create a list if you wish! Let's try that again, but converting to a list:

>>> timeit.timeit('list(itertools.repeat(0, 10))', 'import itertools', number = 1000000)
1.7508119747063233

So if you want a list, use [e] * n. If you want to generate the elements lazily, use repeat.

There is no way to display interactive elements on the lockscreen or wallpaper with a non jailbroken iPhone.

I would recommend Countdown Widget it's free an you can display countdowns in the notification center which you can also access from your lockscreen.

PLEASE ADD REASON FOR DOWNVOTE

• No need to use any external library to extend

• In JavaScript, everything is an object (except for the three primitive datatypes, and even they are automatically wrapped with objects when needed). Furthermore, all objects are mutable.

Class Person in JavaScript

function Person(name, age) {
    this.name = name;
    this.age = age;
}
Person.prototype = {
    getName: function() {
        return this.name;
    },
    getAge: function() {
        return this.age;
    }
}

/* Instantiate the class. */
var alice = new Person('Alice', 93);
var bill = new Person('Bill', 30);

Modify a specific instance/object.

alice.displayGreeting = function() 
{
    alert(this.getGreeting());
}

Modify the class

Person.prototype.getGreeting = function() 
{
    return 'Hi ' + this.getName() + '!';
};

Or simply say : extend JSON and OBJECT both are same

var k = {
    name : 'jack',
    age : 30
}

k.gender = 'male'; /*object or json k got extended with new property gender*/

If you have directory listing disabled in your webserver, then the only way somebody will find it is by guessing or by finding a link to it.

That said, I've seen hacking scripts attempt to "guess" a whole bunch of these common names. "secret.html" would probably be in such a guess list.

The more reasonable solution is to restrict access using a username/password via a htaccess file (for apache) or the equivalent setting for whatever webserver you're using.

Sure, use the .format method. E.g.,

print('{:10s} {:3d}  {:7.2f}'.format('xxx', 123, 98))
print('{:10s} {:3d}  {:7.2f}'.format('yyyy', 3, 1.0))
print('{:10s} {:3d}  {:7.2f}'.format('zz', 42, 123.34))

will print

xxx        123    98.00
yyyy         3     1.00
zz          42   123.34

You can adjust the field sizes as desired. Note that .format works independently of print to format a string. I just used print to display the strings. Brief explanation:

10s format a string with 10 spaces, left justified by default

3d format an integer reserving 3 spaces, right justified by default

7.2f format a float, reserving 7 spaces, 2 after the decimal point, right justfied by default.

There are many additional options to position/format strings (padding, left/right justify etc), String Formatting Operations will provide more information.

Update for f-string mode. E.g.,

text, number, other_number = 'xxx', 123, 98
print(f'{text:10} {number:3d}  {other_number:7.2f}')

For right alignment

print(f'{text:>10} {number:3d}  {other_number:7.2f}')

do this: 1. run CMD (WIN+R then type in CMD) 2. Type this:

set PATH=%PATH%; java installation path\bin

Replace "java installation path" with the directory JDK is installed in, such as C:\Program Files (x86)\Java. Be sure to add the \bin after the JDK directory, because this points to "javac" and "java" (BIN stands for "binaries")

This way, you can run the Java compiler from anywhere. It is impossible to CD to the JDK directory because it has a space in Program Files, and DOS will not let you CD to these directories.

A function is, at a basic level, a block of code that can executed, not when written, but when called. So let's say I have the following piece of code, which is a simple multiplication function:

def multiply(x,y):
    return x * y

So if I called the function with multiply(2,3), it would return the value 6. If I modified the function so it looks like this:

def multiply(x,y):
    print(x*y)
    return x*y

...then the output is as you would expect, the number 6 printed. However, the difference between these two statements is that print merely shows something on the console, but return "gives something back" to whatever called it, which is often a variable. The variable is then assigned the value of the return statement in the function that it called. Here is an example in the python shell:

>>> def multiply(x,y):
        return x*y

>>> multiply(2,3) #no variable assignment
6
>>> answer = multiply(2,3) #answer = whatever the function returns
>>> answer
6

So now the function has returned the result of calling the function to the place where it was called from, which is a variable called 'answer' in this case.

This does much more than simply printing the result, because you can then access it again. Here is an example of the function using return statements:

>>> x = int(input("Enter a number: "))
Enter a number: 5
>>> y = int(input("Enter another number: "))
Enter another number: 6
>>> answer = multiply(x,y)
>>> print("Your answer is {}".format(answer)
Your answer is 30

So it basically stores the result of calling a function in a variable.

The common way is to make the private method protected or package-private and to put the unit test for this method in the same package as the class under test.

"Is it possible to add a key to a Python dictionary after it has been created? It doesn't seem to have an .add() method."

Yes it is possible, and it does have a method that implements this, but you don't want to use it directly.

To demonstrate how and how not to use it, let's create an empty dict with the dict literal, {}:

my_dict = {}

Best Practice 1: Subscript notation

To update this dict with a single new key and value, you can use the subscript notation (see Mappings here) that provides for item assignment:

my_dict['new key'] = 'new value'

my_dict is now:

{'new key': 'new value'}

Best Practice 2: The update method - 2 ways

We can also update the dict with multiple values efficiently as well using the update method. We may be unnecessarily creating an extra dict here, so we hope our dict has already been created and came from or was used for another purpose:

my_dict.update({'key 2': 'value 2', 'key 3': 'value 3'})

my_dict is now:

{'key 2': 'value 2', 'key 3': 'value 3', 'new key': 'new value'}

Another efficient way of doing this with the update method is with keyword arguments, but since they have to be legitimate python words, you can't have spaces or special symbols or start the name with a number, but many consider this a more readable way to create keys for a dict, and here we certainly avoid creating an extra unnecessary dict:

my_dict.update(foo='bar', foo2='baz')

and my_dict is now:

{'key 2': 'value 2', 'key 3': 'value 3', 'new key': 'new value', 
 'foo': 'bar', 'foo2': 'baz'}

So now we have covered three Pythonic ways of updating a dict.

Magic method, __setitem__, and why it should be avoided

There's another way of updating a dict that you shouldn't use, which uses the __setitem__ method. Here's an example of how one might use the __setitem__ method to add a key-value pair to a dict, and a demonstration of the poor performance of using it:

>>> d = {}
>>> d.__setitem__('foo', 'bar')
>>> d
{'foo': 'bar'}


>>> def f():
...     d = {}
...     for i in xrange(100):
...         d['foo'] = i
... 
>>> def g():
...     d = {}
...     for i in xrange(100):
...         d.__setitem__('foo', i)
... 
>>> import timeit
>>> number = 100
>>> min(timeit.repeat(f, number=number))
0.0020880699157714844
>>> min(timeit.repeat(g, number=number))
0.005071878433227539

So we see that using the subscript notation is actually much faster than using __setitem__. Doing the Pythonic thing, that is, using the language in the way it was intended to be used, usually is both more readable and computationally efficient.

In case you don't have some id, e.g., mysite.com/something/9182301, you can use get_object_or_404 importing by from django.shortcuts import get_object_or_404.

Use example:

def myFunc(request, my_pk):
    my_var = get_object_or_404(CLASS_NAME, pk=my_pk)

The reason you cannot import path is because it is new in Django 2.0 as is mentioned here: https://docs.djangoproject.com/en/2.0/ref/urls/#path.

On that page in the bottom right hand corner you can change the documentation version to the version that you have installed. If you do this you will see that there is no entry for path on the 1.11 docs.

Don't add the bcc header.

See this: http://mail.python.org/pipermail/email-sig/2004-September/000151.html

And this: """Notice that the second argument to sendmail(), the recipients, is passed as a list. You can include any number of addresses in the list to have the message delivered to each of them in turn. Since the envelope information is separate from the message headers, you can even BCC someone by including them in the method argument but not in the message header.""" from http://pymotw.com/2/smtplib

toaddr = '[email protected]'
cc = ['[email protected]','[email protected]']
bcc = ['[email protected]']
fromaddr = '[email protected]'
message_subject = "disturbance in sector 7"
message_text = "Three are dead in an attack in the sewers below sector 7."
message = "From: %s\r\n" % fromaddr
    + "To: %s\r\n" % toaddr
    + "CC: %s\r\n" % ",".join(cc)
    # don't add this, otherwise "to and cc" receivers will know who are the bcc receivers
    # + "BCC: %s\r\n" % ",".join(bcc)
    + "Subject: %s\r\n" % message_subject
    + "\r\n" 
    + message_text
toaddrs = [toaddr] + cc + bcc
server = smtplib.SMTP('smtp.sunnydale.k12.ca.us')
server.set_debuglevel(1)
server.sendmail(fromaddr, toaddrs, message)
server.quit()

These paradigms don't have to be mutually exclusive. If you look at python, it supports functions and classes, but at the same time, everything is an object, including functions. You can mix and match functional/oop/procedural style all in one piece of code.

What I mean is, in functional languages (at least in Haskell, the only one I studied) there are no statements! functions are only allowed one expression inside them!! BUT, functions are first-class citizens, you can pass them around as parameters, along with a bunch of other abilities. They can do powerful things with few lines of code.

While in a procedural language like C, the only way you can pass functions around is by using function pointers, and that alone doesn't enable many powerful tasks.

In python, a function is a first-class citizen, but it can contain arbitrary number of statements. So you can have a function that contains procedural code, but you can pass it around just like functional languages.

Same goes for OOP. A language like Java doesn't allow you to write procedures/functions outside of a class. The only way to pass a function around is to wrap it in an object that implements that function, and then pass that object around.

In Python, you don't have this restriction.

The thread.get_ident() function returns a long integer on Linux. It's not really a thread id.

I use this method to really get the thread id on Linux:

import ctypes
libc = ctypes.cdll.LoadLibrary('libc.so.6')

# System dependent, see e.g. /usr/include/x86_64-linux-gnu/asm/unistd_64.h
SYS_gettid = 186

def getThreadId():
   """Returns OS thread id - Specific to Linux"""
   return libc.syscall(SYS_gettid)

The history limit is a pane attribute that is fixed at the time of pane creation and cannot be changed for existing panes. The value is taken from the history-limit session option (the default value is 2000).

To create a pane with a different value you will need to set the appropriate history-limit option before creating the pane.

To establish a different default, you can put a line like the following in your .tmux.conf file:

set-option -g history-limit 3000

Note: Be careful setting a very large default value, it can easily consume lots of RAM if you create many panes.

For a new pane (or the initial pane in a new window) in an existing session, you can set that session’s history-limit. You might use a command like this (from a shell):

tmux set-option history-limit 5000 \; new-window

For (the initial pane of the initial window in) a new session you will need to set the “global” history-limit before creating the session:

tmux set-option -g history-limit 5000 \; new-session

Note: If you do not re-set the history-limit value, then the new value will be also used for other panes/windows/sessions created in the future; there is currently no direct way to create a single new pane/window/session with its own specific limit without (at least temporarily) changing history-limit (though show-option (especially in 1.7 and later) can help with retrieving the current value so that you restore it later).

In addition to the beautiful solution given by @Jon Skeet, I also needed ThenBy and ThenByDescending, so I am adding it based on his solution:

    public static IOrderedEnumerable<TSource> ThenByWithDirection<TSource, TKey>(
         this IOrderedEnumerable<TSource> source, 
         Func<TSource, TKey> keySelector,  
         bool descending)
    {
        return descending ? 
               source.ThenByDescending(keySelector) :
               source.ThenBy(keySelector);
    }

--dev installing devDependencies recursively (and its run forever..) how it can help to resolve the version differences?

You can try remove the node_moduls folder, then clean the npm cache and then run 'npm i' again

I note you suggested this formula

=IF(ISNUMBER(FIND("RuhrP";F9));LOOKUP(A9;Ruhrpumpen!A$5:A$100;Ruhrpumpen!I$5:I$100);"")

.....but LOOKUP isn't appropriate here because I assume you want an exact match (LOOKUP won't guarantee that and also data in lookup range has to be sorted), so VLOOKUP or INDEX/MATCH would be better....and you can also use IFERROR to avoid the IF function, i.e

=IFERROR(VLOOKUP(A9;Ruhrpumpen!A$5:Z$100;9;0);"")

Note: VLOOKUP always looks up the lookup value (A9) in the first column of the "table array" and returns a value from the nth column of the "table array" where n is defined by col_index_num, in this case 9

INDEX/MATCH is sometimes more flexible because you can explicitly define the lookup column and the return column (and return column can be to the left of the lookup column which can't be the case in VLOOKUP), so that would look like this:

=IFERROR(INDEX(Ruhrpumpen!I$5:I$100;MATCH(A9;Ruhrpumpen!A$5:A$100;0));"")

INDEX/MATCH also allows you to more easily return multiple values from different columns, e.g. by using $ signs in front of A9 and the lookup range Ruhrpumpen!A$5:A$100, i.e.

=IFERROR(INDEX(Ruhrpumpen!I$5:I$100;MATCH($A9;Ruhrpumpen!$A$5:$A$100;0));"")

this version can be dragged across to get successive values from column I, column J, column K etc.....

If you just need the core.jar from zxing, you can skip that process and get the pre-built JARs from the GettingStarted wiki page

I did it inside of a jQuery accordion.

$(function() {
        /*video controls*/
            $("#player_video").click(function() {
              if (this.paused == false) {
                  this.pause();
              }
            });
        /*end video controls*/

        var stop = false;
        $("#accordion h3").click(function(event) {
            if (stop) {
                event.stopImmediatePropagation();
                event.preventDefault();
                stop = false;
            }
            $("#player_video").click();
        });

    });

In .NET 4.5 the ZipFile.CreateFromDirectory(startPath, zipPath); method does not cover a scenario where you wish to zip a number of files and sub-folders without having to put them within a folder. This is valid when you wish the unzip to put the files directly within the current folder.

This code worked for me:

public static class FileExtensions
{
    public static IEnumerable<FileSystemInfo> AllFilesAndFolders(this DirectoryInfo dir)
    {
        foreach (var f in dir.GetFiles())
            yield return f;
        foreach (var d in dir.GetDirectories())
        {
            yield return d;
            foreach (var o in AllFilesAndFolders(d))
                yield return o;
        }
    }
}

void Test()
{
    DirectoryInfo from = new DirectoryInfo(@"C:\Test");
    using (FileStream zipToOpen = new FileStream(@"Test.zip", FileMode.Create))
    {
        using (ZipArchive archive = new ZipArchive(zipToOpen, ZipArchiveMode.Create))
        {
            foreach (FileInfo file in from.AllFilesAndFolders().Where(o => o is FileInfo).Cast<FileInfo>())
            {
                var relPath = file.FullName.Substring(from.FullName.Length+1);
                ZipArchiveEntry readmeEntry = archive.CreateEntryFromFile(file.FullName, relPath);
            }
        }
    }
}

Folders don't need to be "created" in the zip-archive. The second parameter "entryName" in CreateEntryFromFile should be a relative path, and when unpacking the zip-file the directories of the relative paths will be detected and created.

For me it worked using flexbox.

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

.parent {
    display: flex;
}

and for the button use:

.button {
    justify-content: center;
}

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

$(document).ready(function() {
    $(body).submit(function () {
        var btn = $(this).find("input[type=submit]:focus");
        if($(btn).prop("id") == "YourButtonID")
            $(btn).attr("disabled", "true");
    });
}

If your error event handler takes the three arguments (xmlhttprequest, textstatus, and message) when a timeout happens, the status arg will be 'timeout'.

Per the jQuery documentation:

Possible values for the second argument (besides null) are "timeout", "error", "notmodified" and "parsererror".

You can handle your error accordingly then.

I created this fiddle that demonstrates this.

$.ajax({
    url: "/ajax_json_echo/",
    type: "GET",
    dataType: "json",
    timeout: 1000,
    success: function(response) { alert(response); },
    error: function(xmlhttprequest, textstatus, message) {
        if(textstatus==="timeout") {
            alert("got timeout");
        } else {
            alert(textstatus);
        }
    }
});?

With jsFiddle, you can test ajax calls -- it will wait 2 seconds before responding. I put the timeout setting at 1 second, so it should error out and pass back a textstatus of 'timeout' to the error handler.

Hope this helps!

No posters have mentioned the contraction of floating expressions yet (ISO C standard, 6.5p8 and 7.12.2). If the FP_CONTRACT pragma is set to ON, the compiler is allowed to regard an expression such as a*a*a*a*a*a as a single operation, as if evaluated exactly with a single rounding. For instance, a compiler may replace it by an internal power function that is both faster and more accurate. This is particularly interesting as the behavior is partly controlled by the programmer directly in the source code, while compiler options provided by the end user may sometimes be used incorrectly.

The default state of the FP_CONTRACT pragma is implementation-defined, so that a compiler is allowed to do such optimizations by default. Thus portable code that needs to strictly follow the IEEE 754 rules should explicitly set it to OFF.

If a compiler doesn't support this pragma, it must be conservative by avoiding any such optimization, in case the developer has chosen to set it to OFF.

GCC doesn't support this pragma, but with the default options, it assumes it to be ON; thus for targets with a hardware FMA, if one wants to prevent the transformation a*b+c to fma(a,b,c), one needs to provide an option such as -ffp-contract=off (to explicitly set the pragma to OFF) or -std=c99 (to tell GCC to conform to some C standard version, here C99, thus follow the above paragraph). In the past, the latter option was not preventing the transformation, meaning that GCC was not conforming on this point: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=37845

General Syntax:

7z a archive_name target parameters

Check your 7-Zip dir. Depending on the release you have, 7z may be replaced with 7za in the syntax.

Parameters:

• -p encrypt and prompt for PW.
• -pPUT_PASSWORD_HERE (this replaces -p) if you want to preset the PW with no prompt.
• -mhe=on to hide file structure, otherwise file structure and names will be visible by default.

Eg. This will prompt for a PW and hide file structures:

7z a archive_name target -p -mhe=on

Eg. No prompt, visible file structure:

7z a archive_name target -pPUT_PASSWORD_HERE

And so on. If you leave target blank, 7z will assume * in current directory and it will recurs directories by default.

If you don't need much in the way of custom behavior, JOptionPane is a good time saver. It takes care of the placement and localization of OK / Cancel options, and is a quick-and-dirty way to show a custom dialog without needing to define your own classes. Most of the time the "message" parameter in JOptionPane is a String, but you can pass in a JComponent or array of JComponents as well.

Example:

JTextField firstName = new JTextField();
JTextField lastName = new JTextField();
JPasswordField password = new JPasswordField();
final JComponent[] inputs = new JComponent[] {
        new JLabel("First"),
        firstName,
        new JLabel("Last"),
        lastName,
        new JLabel("Password"),
        password
};
int result = JOptionPane.showConfirmDialog(null, inputs, "My custom dialog", JOptionPane.PLAIN_MESSAGE);
if (result == JOptionPane.OK_OPTION) {
    System.out.println("You entered " +
            firstName.getText() + ", " +
            lastName.getText() + ", " +
            password.getText());
} else {
    System.out.println("User canceled / closed the dialog, result = " + result);
}

"However I want to share alot of variables and some might be rather large so I don't want to be creating copies of them like above."

That doesn't make a copy (especially with String, but even objects are pass by value of the reference, not the object itself, and getter's like that are fine to use -- arguably better to use than other means because they are common and well understood). The older "performance myths," such as not using getters and setters, still have some value, but have also been updated in the docs.

But if you don't want to do that, you could also just make the variables public or protected in GlobalState and access them directly. And, you can make a static singleton as the Application object JavaDoc indicates:

There is normally no need to subclass Application. In most situation, static singletons can provide the same functionality in a more modular way. If your singleton needs a global context (for example to register broadcast receivers), the function to retrieve it can be given a Context which internally uses Context.getApplicationContext() when first constructing the singleton.

Using Intent data, as other answers here note is another way to pass data, but it's usually used for smaller data and simple types. You can pass larger/more complex data, but it's more involved than just using a static singleon. The Application object is still my personal favorite for sharing larger/more complex non persistent data between Android application components though (because it has a well defined lifecycle in an Android app).

Also, as others have noted, if the data gets very complex and needs to be persistent then you can use SQLite or the filesystem too.

My team encountered the same issue in machines with Windows.. then managed to resolve it in two ways:

a) Set enviroment variable (even in Windows system preferences)

JAVA_TOOL_OPTIONS
-Dfile.encoding=UTF8

b) Introduce following snippet to your pom.xml:

 -Dfile.encoding=UTF-8 

WITHIN

 <jvmArguments>
 -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8001
 -Dfile.encoding=UTF-8
 </jvmArguments>

Just a tip: using http_response_code is much easier to remember than writing the full header:

http_response_code(301);
header('Location: /option-a'); 
exit;

For all those facing a similar issue, I came across this same issue when i was trying to run a particular code snippet, shown below.

<html>
    <head>
        <script>
                var div, container = document.getElementById("container")
                for(var i=0;i<5;i++){
                    div = document.createElement("div");
                    div.onclick = function() { 
                        alert("This is a box #"+i);
                    };
                    container.appendChild(div);
                }
            </script>

    </head>
    <body>
        <div id="container"></div>
    </body>
 </html>

https://codepen.io/pcwanderer/pen/MMEREr

Looking at the error in the console for the above code.

Since the document.getElementById is returning a null and as null does not have a attribute named appendChild, therefore a error is thrown. To solve the issue see the code below.

<html>
    <head>
        <style>
        #container{
            height: 200px;
            width: 700px;
            background-color: red;
            margin: 10px;
        }


        div{
            height: 100px;
            width: 100px;
            background-color: purple;
            margin: 20px;
            display: inline-block;
        }
        </style>
    </head>
    <body>
        <div id="container"></div>
        <script>
                var div, container = document.getElementById("container")
                for(let i=0;i<5;i++){
                    div = document.createElement("div");
                    div.onclick = function() { 
                        alert("This is a box #"+i);
                    };
                    container.appendChild(div);
                }
            </script>
    </body>
</html>

I hope this helps. :)

Copied from my answer here: https://stackoverflow.com/a/9368199/485088

Run ldconfig as root to update the cache - if that still doesn't help, you need to add the path to the file ld.so.conf (just type it in on its own line) or better yet, add the entry to a new file (easier to delete) in directory ld.so.conf.d.

Try this :

ImageView imageview = (ImageView)findViewById(R.id.your_imageview_id);
Bitmap bmp = BitmapFactory.decodeFile(new java.net.URL(your_url).openStream());  
imageview.setImageBitmap(bmp);

You can also try this : Android-Universal-Image-Loader for efficiently loading your image from URL

I wanted to be able to access my application with the HTML5 mode and a fixed token and then switch to the hashbang method (to keep the token so the user can refresh his page).

URL for accessing my app:

http://myapp.com/amazing_url?token=super_token

Then when the user loads the page:

http://myapp.com/amazing_url?token=super_token#/amazing_url

Then when the user navigates:

http://myapp.com/amazing_url?token=super_token#/another_url

With this I keep the token in the URL and keep the state when the user is browsing. I lost a bit of visibility of the URL, but there is no perfect way of doing it.

So don't enable the HTML5 mode and then add this controller:

.config ($stateProvider)->
    $stateProvider.state('home-loading', {
         url: '/',
         controller: 'homeController'
    })
.controller 'homeController', ($state, $location)->
    if window.location.pathname != '/'
        $location.url(window.location.pathname+window.location.search).replace()
    else
        $state.go('home', {}, { location: 'replace' })

In later Elasticsearch versions (7.x), types were removed. Updating a mapping can becomes:

curl -XPUT "http://localhost:9200/test/_mapping" -H 'Content-Type: application/json' -d'{
  "properties": {
    "new_geo_field": {
      "type": "geo_point"
    }
  }
}'

As others have pointed out, if the field exists, you typically have to reindex. There are exceptions, such as adding a new sub-field or changing analysis settings.

You can't "create a mapping", as the mapping is created with the index. Typically, you'd define the mapping when creating the index (or via index templates):

curl -XPUT "http://localhost:9200/test" -H 'Content-Type: application/json' -d'{
  "mappings": {
    "properties": {
      "foo_field": {
        "type": "text"
      }
    }
  }
}'

That's because, in production at least, you'd want to avoid letting Elasticsearch "guess" new fields. Which is what generated this question: geo data was read as an array of long values.

It seems that GSon don't support JAXB. By using JAXB annotated class to create or process the JSON message, I can share the same class to create the Restful Web Service interface by using spring MVC.

Yes. Take a look at this other thread for details: How to apply CSS to iframe?

var cssLink = document.createElement("link");
cssLink.href = "style.css";  
cssLink.rel = "stylesheet";  
cssLink.type = "text/css";  
frames['frame1'].document.body.appendChild(cssLink); 

I had the same problem on a windows host machine and none of the other options here worked for me. I ended up just needing to delete the physical container folder, which was located here:

C:\ProgramData\Docker\containers\[container guid]

I had stopped the docker service first just to be safe and when I restarted it, the broken containers were now gone and I was able to create new ones. I suspect the same will work on a linux host machine, but I do not know where the container folders are kept on that OS.

var val = $.parseJSON(data);
if(val.success == true)
{
 setTimeout(function(){ location.reload(); }, 5000);

}

To display the all details for each news post title ie. "news.id" which is the primary key, you need to use GROUP BY clause for "news.id"

SELECT news.id, users.username, news.title, news.date,
       news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

In this case your while loop will look like

int i = 0;
int a = 0;
while (i < n){
  cin >> a;
  V.push_back(a);
  ++i;
}

If you want to use do() in your main method there are 2 choices because one is static but other (do()) not

1. Create new instance and invoke do() like new Foo().do();
2. make static do() method

Have a look at this sun tutorial

Go to the C drive->user->PcName->find .m2 and Paste the downloaded ojdbc jar file there, Server will automatically pick this.

You are experiencing this issue for two reasons.

• The JPQL Query is not valid.
• You have not created an association between your entities that the underlying JPQL query can utilize.

When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)

User.java

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="iduser")
    private Long idUser;

    @Column(name="user_name")
    private String userName;

    @OneToOne()
    @JoinColumn(name="idarea")
    private Area area;

    public Long getIdUser() {
        return idUser;
    }

    public void setIdUser(Long idUser) {
        this.idUser = idUser;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public Area getArea() {
        return area;
    }

    public void setArea(Area area) {
        this.area = area;
    }
}

Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:

@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")

While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.

Area.java

@Entity
@Table(name = "area")
public class Area {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="idarea")
    private Long idArea;

    @Column(name="area_name")
    private String areaName;

    @OneToOne(fetch=FetchType.LAZY, mappedBy="area")
    private User user;

    public Long getIdArea() {
        return idArea;
    }

    public void setIdArea(Long idArea) {
        this.idArea = idArea;
    }

    public String getAreaName() {
        return areaName;
    }

    public void setAreaName(String areaName) {
        this.areaName = areaName;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
}

ports:

1. Activates the container to listen for specified port(s) from the world outside of the docker(can be same host machine or a different machine) AND also accessible world inside docker.
2. More than one port can be specified (that's is why ports not port)

expose:

1. Activates container to listen for a specific port only from the world inside of docker AND not accessible world outside of the docker.
2. More than one port can be specified

A Swift Approach

This answer builds on the answers above and provides implementation for dealing with the problem of the gradient not being properly applied during rotation. It satisfies this problem by changing the gradient layer to a square so that rotation in all directions results in a correct gradient. The function signature includes a Swift variadic argument that allows one to pass in as many CGColorRef's (CGColor) as needed (see sample usage). Also provided is an example as a Swift extension so that one can apply a gradient to any UIView.

   func configureGradientBackground(colors:CGColorRef...){

        let gradient: CAGradientLayer = CAGradientLayer()
        let maxWidth = max(self.view.bounds.size.height,self.view.bounds.size.width)
        let squareFrame = CGRect(origin: self.view.bounds.origin, size: CGSizeMake(maxWidth, maxWidth))
        gradient.frame = squareFrame

        gradient.colors = colors
        view.layer.insertSublayer(gradient, atIndex: 0)
    }

To use:

in viewDidLoad...

  override func viewDidLoad() {
        super.viewDidLoad()
        configureGradientBackground(UIColor.redColor().CGColor, UIColor.whiteColor().CGColor)
  }

Extension implementation

extension CALayer {


    func configureGradientBackground(colors:CGColorRef...){

        let gradient = CAGradientLayer()

        let maxWidth = max(self.bounds.size.height,self.bounds.size.width)
        let squareFrame = CGRect(origin: self.bounds.origin, size: CGSizeMake(maxWidth, maxWidth))
        gradient.frame = squareFrame

        gradient.colors = colors

        self.insertSublayer(gradient, atIndex: 0)
    }

}

Extension use-case example:

 override func viewDidLoad() {
        super.viewDidLoad()

        self.view.layer.configureGradientBackground(UIColor.purpleColor().CGColor, UIColor.blueColor().CGColor, UIColor.whiteColor().CGColor)
 }

Which means the gradient background can now be applied to any UIControl since all controls are UIViews (or a subclass) and all UIViews have CALayers.

Swift 4

Extension implementation

extension CALayer {
    public func configureGradientBackground(_ colors:CGColor...){

        let gradient = CAGradientLayer()

        let maxWidth = max(self.bounds.size.height,self.bounds.size.width)
        let squareFrame = CGRect(origin: self.bounds.origin, size: CGSize(width: maxWidth, height: maxWidth))
        gradient.frame = squareFrame

        gradient.colors = colors

        self.insertSublayer(gradient, at: 0)
    }    
}

Extension use-case example:

override func viewDidLoad() {
    super.viewDidLoad()

    self.view.layer.configureGradientBackground(UIColor.purple.cgColor, UIColor.blue.cgColor, UIColor.white.cgColor)
}

In my case I had no SDK selected for my project(not sure why). Simply went to Project Structure dialog (alt+ctrl+shift+s or button 1 on the screen) and then to project-> Project SDK's was selected <no SDK>. Just changed it to the latest

You only need to add .Returns(Task.FromResult(0)); after the Callback.

Example:

mock.Setup(arg => arg.DoSomethingAsync())
    .Callback(() => { <my code here> })
    .Returns(Task.FromResult(0));

What you need is an extra spacing div (as far as I understood your question).

This div will be placed between the menu and content and be the same height as the menu div, paddings included.

HTML

<div id="fixed-menu">
    Navigation options or whatever.
</div>
<div class="spacer">
    &nbsp;
</div>
<div id="content">
    Content.
</div>

CSS

#fixed-menu
{
    position: fixed;
    width: 100%;
    height: 75px;
    background-color: #f00;
    padding: 10px;
}

.spacer
{
    width: 100%;
    height: 95px;
}

See my example here.

This works by offsetting the space that would have been occupied by the nav div, but as it has position: fixed; it has been taken out of the document flow.

The preferred method of achieving this effect is by using margin-top: 95px;/*your nav height*/ on your content wrapper.

Just uninstall whatever node version you have in your system. Then go to this site https://nodejs.org/download/release/ and choose your desired version like for me its like v7.0.0/ and click on that go get .msi file of that. Finally you will get installer in your system, so install it. It will solve all your problems.

int valInt = 12;
Console.WriteLine(valInt.ToString("X"));  // C  ~ possibly single-digit output 
Console.WriteLine(valInt.ToString("X2")); // 0C ~ always double-digit output

When you might be looking to find multiple column matches, a vectorized solution using searchsorted method could be used. Thus, with df as the dataframe and query_cols as the column names to be searched for, an implementation would be -

def column_index(df, query_cols):
    cols = df.columns.values
    sidx = np.argsort(cols)
    return sidx[np.searchsorted(cols,query_cols,sorter=sidx)]

Sample run -

In [162]: df
Out[162]: 
   apple  banana  pear  orange  peach
0      8       3     4       4      2
1      4       4     3       0      1
2      1       2     6       8      1

In [163]: column_index(df, ['peach', 'banana', 'apple'])
Out[163]: array([4, 1, 0])

Remove the quotes here:

is:

ORDER BY = 'post_datetime DESC' AND LIMIT = '3'

Should be:

ORDER BY post_datetime DESC LIMIT 3

In Eclipse: right-click on your project -> Export -> JAR file

At last page with options (when there will be no Next button active) you will see settings for Main class:. You need to set here class with main method which should be executed by default (like when JAR file will be double-clicked).

Try below for your query. where val is your string or column name.

CASE WHEN PATINDEX('%[a-z]%', REVERSE(val)) > 1
                THEN LEFT(val, LEN(val) - PATINDEX('%[a-z]%', REVERSE(val)) + 1)
            ELSE '' END

You can also do this to just get the field titles:

table = cursor.description
check = 0
for fields in table:
    for name in fields:
        if check < 1:
            print(name),
        check +=1
    check =0

This is more of an xpath question, but like this, assuming the context is the parent element:

<xsl:value-of select="name/@attribute1" />

I believe the simplest thing to do is:

#assuming three sets
set1 = {1,2,3,4,5}
set2 = {2,3,8,9}
set3 = {2,10,11,12}

#intersection
set4 = set1 & set2 & set3

set4 will be the intersection of set1 , set2, set3 and will contain the value 2.

print(set4)

set([2])

Using ES6 syntax in React does not bind this to user-defined functions however it will bind this to the component lifecycle methods.

So the function that you declared will not have the same context as the class and trying to access this will not give you what you are expecting.

For getting the context of class you have to bind the context of class to the function or use arrow functions.

Method 1 to bind the context:

class MyContainer extends Component {

    constructor(props) {
        super(props);
        this.onMove = this.onMove.bind(this);
        this.testVarible= "this is a test";
    }

    onMove() {
        console.log(this.testVarible);
    }
}

Method 2 to bind the context:

class MyContainer extends Component {

    constructor(props) {
        super(props);
        this.testVarible= "this is a test";
    }

    onMove = () => {
        console.log(this.testVarible);
    }
}

Method 2 is my preferred way but you are free to choose your own.

Update: You can also create the properties on class without constructor:

class MyContainer extends Component {

    testVarible= "this is a test";

    onMove = () => {
        console.log(this.testVarible);
    }
}

Note If you want to update the view as well, you should use state and setState method when you set or change the value.

Example:

class MyContainer extends Component {

    state = { testVarible: "this is a test" };

    onMove = () => {
        console.log(this.state.testVarible);
        this.setState({ testVarible: "new value" });
    }
}

To answer the non-reproducability aspect of the question - Firefox automatically imports intermediate certificates into its certificate store. So if you've previously visited a site which has used the same Intermediate Certificate using a correctly configured certificate chain then Firefox will store that Certificate so you will not see the problem when you visit a site that has an incorrectly configured chain using the same Intermediate certificate.

You can check this in Firefox's Certificate Manager (Options->Privacy&Security->View Certificates...) where you can see all stored certificates. Under the 'Security Device' Column you can check where a certificate has come from - automatically/manually imported certificates will appear as from 'Software Security Device' as opposed to the 'Builtin Object Token', which are the default set installed with Firefox. You can delete/Distrust any specific certificates and test again.

Could do it with :contains() selector as well:

$('#toptitle:contains("Profil")').text("New word");

You can update your python version to 3.8 in conda using the command

conda install -c anaconda python=3.8

as per https://anaconda.org/anaconda/python. Though not all packages support 3.8 yet, running

conda update --all

may resolve some dependency failures. You can also create a new environment called py38 using this command

conda create -n py38 python=3.8

Edit - note that the conda install option will potentially take a while to solve the environment, and if you try to abort this midway through you will lose your Python installation (usually this means it will resort to non-conda pre-installed system Python installation).

If you are using eclipse try:

Window > Preferences > Android > Launch

Default emulator options: -dns-server 8.8.8.8,8.8.4.4

So the key parts are to grab the header ( col_names = s.row(0) ) and when iterating through the rows, to skip the first row which isn't needed for row in range(1, s.nrows) - done by using range from 1 onwards (not the implicit 0). You then use zip to step through the rows holding 'name' as the header of the column.

from xlrd import open_workbook

wb = open_workbook('Book2.xls')
values = []
for s in wb.sheets():
    #print 'Sheet:',s.name
    for row in range(1, s.nrows):
        col_names = s.row(0)
        col_value = []
        for name, col in zip(col_names, range(s.ncols)):
            value  = (s.cell(row,col).value)
            try : value = str(int(value))
            except : pass
            col_value.append((name.value, value))
        values.append(col_value)
print values

I couldn't figure out why popen/pclose is missing from Code::Blocks/MinGW. So I worked around the problem by using CreateProcess() and CreatePipe() instead.

Here's the solution that worked for me:

Sometimes it takes longer to figure out the regex than to just write it out in python:

import string
s = "how much for the maple syrup? $20.99? That's ricidulous!!!"
for char in string.punctuation:
    s = s.replace(char, ' ')

If you need other characters you can change it to use a white-list or extend your black-list.

Sample white-list:

whitelist = string.letters + string.digits + ' '
new_s = ''
for char in s:
    if char in whitelist:
        new_s += char
    else:
        new_s += ' '

Sample white-list using a generator-expression:

whitelist = string.letters + string.digits + ' '
new_s = ''.join(c for c in s if c in whitelist)

I usually combine PointToScreen and PointToClient:

Point locationOnForm = control.FindForm().PointToClient(
    control.Parent.PointToScreen(control.Location));

@wdavo is correct. The same is also true for functions.

If you override a base function, like Update, then in your subclass you need:

new void Update()
{
  //do stufff
}

Without the new at the start of the function decleration you will get the warning flag.

Take a look into NSColorWell class reference.

If you have saved the excel file in the same folder as your python program (relative paths) then you just need to mention sheet number along with file name.

Example:

 data = pd.read_excel("wt_vs_ht.xlsx", "Sheet2")
 print(data)
 x = data.Height
 y = data.Weight
 plt.plot(x,y,'x')
 plt.show()

R.color.red is an ID (which is also an int), but is not a color.

Use one of the following instead:

// If you're in an activity:
Button11.setBackgroundColor(getResources().getColor(R.color.red));
// OR, if you're not: 
Button11.setBackgroundColor(Button11.getContext().getResources().getColor(R.color.red));

Or, alternatively:

Button11.setBackgroundColor(Color.RED); // From android.graphics.Color

Or, for more pro skills:

Button11.setBackgroundColor(0xFFFF0000); // 0xAARRGGBB

As others have noted, most likely you don't have .html set up to handle php code.

Having said that, if all you're doing is using index.html to include index.php, your question should probably be 'how do I use index.php as index document?

In which case, for Apache (httpd.conf), search for DirectoryIndex and replace the line with this (will only work if you have dir_module enabled, but that's default on most installs):

DirectoryIndex index.php

If you use other directory indexes, list them in order of preference i.e.

DirectoryIndex index.php index.phtml index.html index.htm

if you are using Maven 2.0.8+, then it will be very simple, run mvndebug from the console, and connect to it via Remote Debug Java Application with port 8000.

If you want to use all stylesheet in your app just adds this line in application.html.erb. Insert it inside <head> tag

  <%= stylesheet_link_tag  controller.controller_name , media: 'all', 'data-turbolinks-track': 'reload' %>

Also, to specify the same class CSS on a different controller
Add this line in the body of application.html.erb

  <body class="<%= controller.controller_name %>-<%= controller.action_name %>">

So, now for example I would like to change the p tag in 'home' controller and 'index' action. Inside index.scss file adds.

.nameOfController-nameOfAction <tag> { }

 .home-index p {
        color:red !important;
      }

String.Empty and string.Empty are equivalent. String is the BCL class name; string is its C# alias (or shortcut, if you will). Same as with Int32 and int. See the docs for more examples.

As far as "" is concerned, I'm not really sure.

Personally, I always use string.Empty.

Yes the culprit is definitely word-wrapping. When I tested your two programs, NetBeans IDE 8.2 gave me the following result.

1. First Matrix: O and # = 6.03 seconds
2. Second Matrix: O and B = 50.97 seconds

Looking at your code closely you have used a line break at the end of first loop. But you didn't use any line break in second loop. So you are going to print a word with 1000 characters in the second loop. That causes a word-wrapping problem. If we use a non-word character " " after B, it takes only 5.35 seconds to compile the program. And If we use a line break in the second loop after passing 100 values or 50 values, it takes only 8.56 seconds and 7.05 seconds respectively.

Random r = new Random();
for (int i = 0; i < 1000; i++) {
    for (int j = 0; j < 1000; j++) {
        if(r.nextInt(4) == 0) {
            System.out.print("O");
        } else {
            System.out.print("B");
        }
        if(j%100==0){               //Adding a line break in second loop      
            System.out.println();
        }                    
    }
    System.out.println("");                
}

Another advice is that to change settings of NetBeans IDE. First of all, go to NetBeans Tools and click Options. After that click Editor and go to Formatting tab. Then select Anywhere in Line Wrap Option. It will take almost 6.24% less time to compile the program.

It's

In my situation, we are using Git Flow and GitHub. All you need to do this is: Compare your feature branch with your develop branch on GitHub.

It will show the commits only made to your feature branch.

For example:

https://github.com/your_repo/compare/develop...feature_branch_name

For me : Build->Clean Project solved this question

To give the second rule higher specificity you can always use parts of the first rule. In this case I would add table.rule1 trfrom rule one and add it to rule two.

table.rule1 tr td {
    background-color: #ff0000;
}

table.rule1 tr td.rule2 {
    background-color: #ffff00;
}

After a while I find this gets natural, but I know some people disagree. For those people I would suggest looking into LESS or SASS.

Better Way -

        double value = 10.567;
        int result = (int)((value - (int)value) * 100);
        Console.WriteLine(result);

Output -

This is a program to show how to give input from system and also calculate sum at each level and average.

package NumericTest;

import java.util.Scanner;

public class SumAvg {


 public static void main(String[] args) {

 int i,n;
 System.out.println("Enter the number of inputs");
 Scanner sc = new Scanner(System.in);
 n=sc.nextInt();
 int a[] = new int [n];

    System.out.println("Enter the inputs");
   for(i=0;i<n;i++){
   a[i] = sc.nextInt();
  System.out.println("Inputs are " +a[i]);
 }

  int sum = 0;
  for(i=0;i<n;i++){
 sum = sum +a[i];
  System.out.println("Sums : " +sum);
 }
  int avg ;
  avg = sum/n;
  System.out.println("avg : " +avg);
  }
 }

I want to point out one behavior of BackgroundWorker class that wasn't mentioned yet. You can make a normal Thread to run in background by setting the Thread.IsBackground property.

Background threads are identical to foreground threads, except that background threads do not prevent a process from terminating. [1]

You can test this behavoir by calling the following method in the constructor of your form window.

void TestBackgroundThread()
{
    var thread = new Thread((ThreadStart)delegate()
    {
        long count = 0;
        while (true)
        {
            count++;
            Debug.WriteLine("Thread loop count: " + count);
        }
    });

    // Choose one option:
    thread.IsBackground = true; // <--- This will make the thread run in background
    thread.IsBackground = false; // <--- This will delay program termination

    thread.Start();
}

When the IsBackground property is set to true and you close the window, then your application will terminate normaly.

But when the IsBackground property is set to false (by default) and you close the window, then just the window will disapear but the process will still keep running.

The BackgroundWorker class utilize a Thread that runs in the background.

Jeremy Keith (@adactio) has a good solution for this on his blog Orientation and scale

Keep the Markup scalable by not setting a maximum-scale in markup.

<meta name="viewport" content="width=device-width, initial-scale=1">

Then disable scalability with javascript on load until gesturestart when you allow scalability again with this script:

if (navigator.userAgent.match(/iPhone/i) || navigator.userAgent.match(/iPad/i)) {
    var viewportmeta = document.querySelector('meta[name="viewport"]');
    if (viewportmeta) {
        viewportmeta.content = 'width=device-width, minimum-scale=1.0, maximum-scale=1.0, initial-scale=1.0';
        document.body.addEventListener('gesturestart', function () {
            viewportmeta.content = 'width=device-width, minimum-scale=0.25, maximum-scale=1.6';
        }, false);
    }
}

Update 22-12-2014:
On an iPad 1 this doesnt work, it fails on the eventlistener. I've found that removing .body fixes that:

document.addEventListener('gesturestart', function() { /* */ });

'Caret' is the word you are looking for. I do believe though, that it is part of the browsers design, and not within the grasp of css.

However, here is an interesting write up on simulating a caret change using Javascript and CSS http://www.dynamicdrive.com/forums/showthread.php?t=17450 It seems a bit hacky to me, but probably the only way to accomplish the task. The main point of the article is:

We will have a plain textarea somewhere in the screen out of the view of the viewer and when the user clicks on our "fake terminal" we will focus into the textarea and when the user starts typing we will simply append the data typed into the textarea to our "terminal" and that's that.

HERE is a demo in action

2018 update

There is a new css property caret-color which applies to the caret of an input or contenteditable area. The support is growing but not 100%, and this only affects color, not width or other types of appearance.

input{_x000D_
  caret-color: rgb(0, 200, 0);_x000D_
}

<input type="text"/>

Using jQuery:

 $('#link_other a').each(function(){
  $(this).attr('target', '_BLANK');
 });
