You should use the OO interface to matplotlib, rather than the state machine interface. Almost all of the plt.* function are thin wrappers that basically do gca().*.

plt.subplot returns an axes object. Once you have a reference to the axes object you can plot directly to it, change its limits, etc.

import matplotlib.pyplot as plt

ax1 = plt.subplot(131)
ax1.scatter([1, 2], [3, 4])
ax1.set_xlim([0, 5])
ax1.set_ylim([0, 5])


ax2 = plt.subplot(132)
ax2.scatter([1, 2],[3, 4])
ax2.set_xlim([0, 5])
ax2.set_ylim([0, 5])

and so on for as many axes as you want.

or better, wrap it all up in a loop:

import matplotlib.pyplot as plt

DATA_x = ([1, 2],
          [2, 3],
          [3, 4])

DATA_y = DATA_x[::-1]

XLIMS = [[0, 10]] * 3
YLIMS = [[0, 10]] * 3

for j, (x, y, xlim, ylim) in enumerate(zip(DATA_x, DATA_y, XLIMS, YLIMS)):
    ax = plt.subplot(1, 3, j + 1)
    ax.scatter(x, y)
    ax.set_xlim(xlim)
    ax.set_ylim(ylim)

Use HTML textarea with runat="server" to access it in server side. This solution has less pain than using javascript or regex.

<textarea runat="server" id="txt1" maxlength="100" />

Note: To access Text Property in server side, you should use txt1.Value instead of txt1.Text

Maybe you can use arrow function (ES6+) or the simple old function declaration.

Normal function declaration type (Not ES6+):

<link href="#" onClick={function(event){ func1(event); func2();}}>Trigger here</link>

Anonymous function or arrow function type (ES6+)

<link href="#" onClick={(event) => { func1(event); func2();}}>Trigger here</link>

The second one is the shortest road that I know. Hope it helps you!

Let consider that your data are in the file values.txt and that you want to import them in the database table myTable then the following query does the job

COPY myTable FROM 'value.txt' (DELIMITER('|'));

https://www.postgresql.org/docs/current/static/sql-copy.html

I had a similar problem recently. I had a form and PHP function that to be run once the form is submitted. However, I needed to run a javascript first.

        // This variable is used in order to determine if we already did our js fun
        var window.alreadyClicked = "NO"
        $("form:not('#press')").bind("submit", function(e){
            // Check if we already run js part
            if(window.alreadyClicked == "NO"){
                // Prevent page refresh
                e.preventDefault();
                // Change variable value so next time we submit the form the js wont run
                window.alreadyClicked = "YES"
                // Here is your actual js you need to run before doing the php part
                xxxxxxxxxx

                // Submit the form again but since we changed the value of our variable js wont be run and page can reload (and php can do whatever you told it to)
                $("form:not('#press')").submit()
            } 
        });

The \s regex argument is not compatible with UTF-8 multybyte strings.

This PHP RegEx is one I wrote to solve this using PCRE (Perl Compatible Regular Expressions) based arguments as a replacement for UTF-8 strings:

function remove_utf8_whitespace($string) { 
   return preg_replace('/\h+/u','',preg_replace('/\R+/u','',$string)); 
}

- Example Usage -

Before:

$string = " this is a test \n and another test\n\r\t ok! \n";

echo $string;

 this is a test
 and another test
         ok!

echo strlen($string); // result: 43

After:

$string = remove_utf8_whitespace($string);

echo $string;

thisisatestandanothertestok!

echo strlen($string); // result: 28

Using Angular Cli

 npm install jquery --save

In angular.json under scripts array

"scripts": [ "node_modules/jquery/dist/jquery.min.js" ] // copy relative path of node_modules>jquery>dist>jquery.min.js to avoid path error

Now to use jQuery, all you have to do is to import it as follows in whatever component you want to use jQuery.

For example importing and using jQuery in root component

import { Component, OnInit  } from '@angular/core';
import * as $ from 'jquery'; // I faced issue in using jquery's popover
Or
declare var $: any; // declaring jquery in this way solved the problem

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {


ngOnInit() {
}

jQueryExampleModal() { // to show a modal with dummyId
   $('#dummyId').modal('show');
}

System.getProperties() can be overridden by calls to System.setProperty(String key, String value) or with command line parameters -Dfile.separator=/

File.separator gets the separator for the default filesystem.

FileSystems.getDefault() gets you the default filesystem.

FileSystem.getSeparator() gets you the separator character for the filesystem. Note that as an instance method you can use this to pass different filesystems to your code other than the default, in cases where you need your code to operate on multiple filesystems in the one JVM.

df[df.columns[i]]

where i is the position/number of the column(starting from 0).

So, i = 0 is for the first column.

You can also get the last column using i = -1

Try this:

 >>> f = open('goodlines.txt')
 >>> mylist = f.readlines()

open() function returns a file object. And for file object, there is no method like splitlines() or split(). You could use dir(f) to see all the methods of file object.

I run the service at IPLocate.io, which you can hook into for free with one easy call:

<?php
$res = file_get_contents('https://www.iplocate.io/api/lookup/8.8.8.8');
$res = json_decode($res);

echo $res->country; // United States
echo $res->continent; // North America
echo $res->latitude; // 37.751
echo $res->longitude; // -97.822

var_dump($res);

The $res object will contain your geolocation fields like country, city, etc.

Check out the docs for more information.

There's a problem with ef seeding db from Startup.Configure in 2.0 ... you can still do it with this work around. Tested and worked fine

If you don't care about legacy browsers:

if ( bank_holidays.indexOf( '06/04/2012' ) > -1 )

if you do care about legacy browsers, there is a shim available on MDN. Otherwise, jQuery provides an equivalent function:

if ( $.inArray( '06/04/2012', bank_holidays ) > -1 )

Woe, there's so many ways to do this. I came up with this, short and simple. Hope this help others.

  var url = document.location.toString();
  if (url.match('#')) {
    $('.nav-tabs a[href="#' + url.split('#')[1] + '"]').tab('show');
  } 

  $('.nav-tabs a').on('shown.bs.tab', function (e) {
    window.location.hash = e.target.hash;
    if(e.target.hash == "#activity"){
      $('.nano').nanoScroller();
    }
  })

To push up through a given commit, you can write:

git push <remotename> <commit SHA>:<remotebranchname>

provided <remotebranchname> already exists on the remote. (If it doesn't, you can use git push <remotename> <commit SHA>:refs/heads/<remotebranchname> to autocreate it.)

If you want to push a commit without pushing previous commits, you should first use git rebase -i to re-order the commits.

The newest version of the Anaconda installer for Windows will also install a windows launcher for "Anaconda Prompt" and "Anaconda Powershell Prompt". If you use one of those instead of the regular windows cmd shell, the conda command, python etc. should be available by default in this shell.

I know you are long past getting a solution. So, this is for others that come along to see how other people are solving the same common problem-- like me.

The examples in the question and answers indicates the use of jQuery and I am using the .change listener/handler/whatever to see if my textarea changes. This should take care of manual text changes, automated text changes, etc. to trigger the

//pseudocode
$(document).ready(function () {
    $('#textarea').change(function () {
        if ($.trim($('#textarea').val()).length < 1) {

            $('#output').html('Someway your box is being reported as empty... sadness.');

        } else {

            $('#output').html('Your users managed to put something in the box!');
            //No guarantee it isn't mindless gibberish, sorry.

        }
    });
});

Seems to work on all the browsers I use. http://jsfiddle.net/Q3LW6/. Message shows when textarea loses focus.

Newer, more thorough example: https://jsfiddle.net/BradChesney79/tjj6338a/

Uses and reports .change(), .blur(), .keydown(), .keyup(), .mousedown(), .mouseup(), .click(), mouseleave(), and .setInterval().

It's pretty strange for FB not to be loaded in your javascript if you have the script tag there correctly. Check that you don't have any javascript blockers, ad blockers, tracking blockers etc installed in your browser that are neutralizing your FB Connect code.

I found the product key for Visual Studio 2008 Professional under a slightly different key:

HKLM\SOFTWARE\Wow6432Node\Microsoft\MSDN\8.0\Registration\PIDKEY

it was listed without the dashes as stated above.

That's a specific case of the rule that you shouldn't catch any exception you don't know how to handle. If you don't know how to handle it, it's always better to let some other part of the system catch and handle it.

String formatting using % is a great way to handle this. Here are some examples.

The formatting code '%s' converts '12345' to a string, but it's already a string.

>>> '%s' % '12345'

'12345'

'%.3s' specifies to use only the first three characters.

>>> '%.3s' % '12345'

'123'

'%.7s' says to use the first seven characters, but there are only five. No problem.

>>> '%.7s' % '12345'

'12345'

'%7s' uses up to seven characters, filling missing characters with spaces on the left.

>>> '%7s' % '12345'

'  12345'

'%-7s' is the same thing, except filling missing characters on the right.

>>> '%-7s' % '12345'

'12345  '

'%5.3' says use the first three characters, but fill it with spaces on the left to total five characters.

>>> '%5.3s' % '12345'

'  123'

Same thing except filling on the right.

>>> '%-5.3s' % '12345'

'123  '

Can handle multiple arguments too!

>>> 'do u no %-4.3sda%3.2s wae' % ('12345', 6789)

'do u no 123 da 67 wae'

If you require even more flexibility, str.format() is available too. Here is documentation for both.

You can enable TLS 1.2 in IIS by following these instructions. I presume this would be sufficient if you have an ASP.NET-based application that runs on top of IIS, although it looks like it does not really meet your needs.

Can't comment due to reputation, so I'm making another answer:

In this case you will also have to remove the generally suggested display: block; property from the element you set the text-overflow: ellipsis; on, or it will cut off without the ... at the end.

You could also use:

<body onload="focusOnInput()">
    <form name="passwordForm" action="verify.php" method="post">
        <input name="passwordInput" type="password" />
    </form>
</body>

And then in your JavaScript:

function focusOnInput() {
    document.forms["passwordForm"]["passwordInput"].focus();
}

To unify all of the screens to show same element sizes including font size: - Design the UI on one screen size with whatever sizes you find appropriate during the design i.e. TextView font size is 14dp on default screen size with 4'6 inches.

• Programmatically calculate the physical screen size of the other phones i.e. 5'2 inches of other phones/screens.

• Use a formula to calculate the percentage difference between the 2 screens. i.e. what's the % difference between 4'6 and 5'2.

• Calculate the pixel difference between the 2 TextViews based on the above formula.

• Get the actual size (in pixels) of the TextView font-size and apply the pixels difference (you calculated earlier) to the default font-size.

With this way you can apply dynamic aspect ratio to all of screen sizes and the result is great. You'll have identical layout and sizes on each screen.

It can be a bit tricky at first but totally achieves the goal once you figure the formula out. With this method you don't need to make multiple layouts just to fit different screen sizes.

You can find a nice list of corresponding URL encoded characters on W3Schools.

• space becomes %20

The source code for the Android mobile application open-gpstracker which you appreciated is available here.

You can checkout the code using SVN client application or via Git:

• svn checkout http://open-gpstracker.googlecode.com/svn/trunk/ open-gpstracker-read-only
• git clone https://code.google.com/p/open-gpstracker/

Debugging the source code will surely help you.

Just in case if someone is wondering to save the CSV file to a specific path for email attachments. Then it can be done as follows

I know I have added a lot of comments just for newbies :)

I have added an example so that you can summarize well.

$activeUsers = /** Query to get the active users */

/** Following is the Variable to store the Users data as 
    CSV string with newline character delimiter, 

    its good idea of check the delimiter based on operating system */

$userCSVData = "Name,Email,CreatedAt\n";

/** Looping the users and appending to my earlier csv data variable */
foreach ( $activeUsers as $user ) {
    $userCSVData .= $user->name. "," . $user->email. "," . $user->created_at."\n";
}
/** Here you can use with H:i:s too. But I really dont care of my old file  */
$todayDate  = date('Y-m-d');
/** Create Filname and Path to Store */
$fileName   = 'Active Users '.$todayDate.'.csv';
$filePath   = public_path('uploads/'.$fileName); //I am using laravel helper, in case if your not using laravel then just add absolute or relative path as per your requirements and path to store the file

/** Just in case if I run the script multiple time 
    I want to remove the old file and add new file.

    And before deleting the file from the location I am making sure it exists */
if(file_exists($filePath)){
    unlink($filePath);
}
$fp = fopen($filePath, 'w+');
fwrite($fp, $userCSVData); /** Once the data is written it will be saved in the path given */
fclose($fp);

/** Now you can send email with attachments from the $filePath */

NOTE: The following is a very bad idea to increase the memory_limit and time limit, but I have only added to make sure if anyone faces the problem of connection time out or any other. Make sure to find out some alternative before sticking to it.

You have to add the following at the start of the above script.

ini_set("memory_limit", "10056M");
set_time_limit(0);
ini_set('mysql.connect_timeout', '0');
ini_set('max_execution_time', '0');

The + (String Concatenation) does not work on SQL Server for the image, ntext, or text data types.

In fact, image, ntext, and text are all deprecated.

ntext, text, and image data types will be removed in a future version of MicrosoftSQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

That said if you are using an older version of SQL Server than you want to use UPDATETEXT to perform your concatenation. Which Colin Stasiuk gives a good example of in his blog post String Concatenation on a text column (SQL 2000 vs SQL 2005+).

The first push should be a:

git push -u origin branchname

That would make sure:

• your local branch has a remote tracking branch of the same name referring an upstream branch in your remote repo 'origin',
• this is compliant with the default push policy 'simple'

Any future git push will, with that default policy, only push the current branch, and only if that branch has an upstream branch with the same name.
that avoid pushing all matching branches (previous default policy), where tons of test branches were pushed even though they aren't ready to be visible on the upstream repo.

Regex for minimum 8 char, one alpha, one numeric and one special char:

/^(?=.*[A-Za-z])(?=.*\d)(?=.*[!@#$%^&*])[A-Za-z\d!@#$%^&*]{8,}$/

Combining @Joachim's with the above, you could use

next(iter(my_list[index:index+1]), default)

Examples:

next(iter(range(10)[8:9]), 11)
8
>>> next(iter(range(10)[12:13]), 11)
11

Or, maybe more clear, but without the len

my_list[index] if my_list[index:index + 1] else default

I ran into this problem and try using the flag -noverify which really works. It is because of the new bytecode verifier. So the flag should really work. I am using JDK 1.7.

Note: This would not work if you are using JDK 1.8

I believe that the problem is that the WebRequest measures the time only after the request is actually made. If you submit multiple requests to the same address then the ServicePointManager will throttle your requests and only actually submit as many concurrent connections as the value of the corresponding ServicePoint.ConnectionLimit which by default gets the value from ServicePointManager.DefaultConnectionLimit. Application CLR host sets this to 2, ASP host to 10. So if you have a multithreaded application that submits multiple requests to the same host only two are actually placed on the wire, the rest are queued up.

I have not researched this to a conclusive evidence whether this is what really happens, but on a similar project I had things were horrible until I removed the ServicePoint limitation.

Another factor to consider is the DNS lookup time. Again, is my belief not backed by hard evidence, but I think the WebRequest does not count the DNS lookup time against the request timeout. DNS lookup time can show up as very big time factor on some deployments.

And yes, you must code your app around the WebRequest.BeginGetRequestStream (for POSTs with content) and WebRequest.BeginGetResponse (for GETs and POSTSs). Synchronous calls will not scale (I won't enter into details why, but that I do have hard evidence for). Anyway, the ServicePoint issue is orthogonal to this: the queueing behavior happens with async calls too.

Hopefully someone else finds this useful:

Using the Join is the best way to use a multi-value parameter. But what if you want to have an efficient 'Select All'? If there are 100s+ then the query will be very inefficient.

To solve this instead of using a SQL Query as is, change it to using an expression (click the Fx button top right) then build your query something like this (speech marks are necessary):

= "Select * from tProducts Where 1 = 1 " 
IIF(Parameters!ProductID.Value(0)=-1,Nothing," And ProductID In (" & Join(Parameters!ProductID.Value,"','") & ")")

In your Parameter do the following:

    SELECT -1 As ProductID, 'All' as ProductName Union All
    Select  
    tProducts.ProductID,tProducts.ProductName
    FROM
    tProducts

By building the query as an expression means you can make the SQL Statement more efficient but also handle the difficulty SQL Server has with handling values in an 'In' statement.

Here is a working example. I changed the code to output to a div instead of an alert box. Your issue was item.innerHTML I believe. I use the jQuery html function instead and that seemed to resolve the issue.

<table id='thisTable' class='disptable' style='margin-left:auto;margin-right:auto;'  >
    <tr>

   <th>Fund</th>
   <th>Organization</th>
   <th>Access</th>
   <th>Delete</th>
   </tr>
    <tr>
   <td class='fund'>100000</td><td class='org'>10110</td><td>OWNED</td><td><a  class='delbtn'ref='#'>X</a></td></tr>
   <tr><td class='fund'>100000</td><td class='org'>67130</td><td>OWNED</td><td><a class='delbtn' href='#'>X</a></td></tr>
   <tr><td class='fund'>170252</td><td class='org'>67130</td><td>OWNED</td><td><a class='delbtn' href='#'>X</a></td></tr>
   <tr><td class='fund'>100000</td><td class='org'>67150</td><td>PENDING ACCESS</td><td><a  class='delbtn' href='#'>X</a></td></tr>
   <tr><td class='fund'>100000</td><td class='org'>67120</td><td>PENDING ACCESS</td><td><a class='delbtn' href='#'>X</a>
   </td>
  </tr>
</table>
<div id="output"></div>?

the javascript:

$('#thisTable tr').on('click', function(event) {    
    var tds = $(this).addClass('row-highlight').find('td');
    var values = '';
    tds.each(function(index, item) {           
        values = values + 'td' + (index + 1) + ':' + $(item).html() + '<br/>';
    });
    $("#output").html(values);
});

Sometimes you may need to plot color precisely based on the x-value case. For example, you may have a dataframe with 3 types of variables and some data points. And you want to do following,

• Plot points corresponding to Physical variable 'A' in RED.
• Plot points corresponding to Physical variable 'B' in BLUE.
• Plot points corresponding to Physical variable 'C' in GREEN.

In this case, you may have to write to short function to map the x-values to corresponding color names as a list and then pass on that list to the plt.scatter command.

x=['A','B','B','C','A','B']
y=[15,30,25,18,22,13]

# Function to map the colors as a list from the input list of x variables
def pltcolor(lst):
    cols=[]
    for l in lst:
        if l=='A':
            cols.append('red')
        elif l=='B':
            cols.append('blue')
        else:
            cols.append('green')
    return cols
# Create the colors list using the function above
cols=pltcolor(x)

plt.scatter(x=x,y=y,s=500,c=cols) #Pass on the list created by the function here
plt.grid(True)
plt.show()

To access a variable in a class, you must use $this->myVar instead of $this->$myvar.

And, you should use access identifier to declare a variable instead of var.

Starting with Spring Boot 1.2, you can configure SSL using application.properties or application.yml. Here's an example for application.properties:

server.port = 8443
server.ssl.key-store = classpath:keystore.jks
server.ssl.key-store-password = secret
server.ssl.key-password = another-secret

Same thing with application.yml:

server:
  port: 8443
  ssl:
    key-store: classpath:keystore.jks
    key-store-password: secret
    key-password: another-secret

I have created a javascript function that looks if he has enough space on the right side. If it has he will show it on the right side, else he will display it on the left side

Tested in:

• Firefox (mac)
• Chorme (mac)
• Safari (mac)

Javascript:

$(document).ready(function(){
    //little fix for the poisition.
    var newPos     = $(".fixed-menuprofile .dropdown-submenu").offset().left - $(this).width();
    $(".fixed-menuprofile .dropdown-submenu").find('ul').offset({ "left": newPos });

    $(".fixed-menu .dropdown-submenu").mouseover(function() {
        var submenuPos = $(this).offset().left + 325;
        var windowPos  = $(window).width();
        var oldPos     = $(this).offset().left + $(this).width();
        var newPos     = $(this).offset().left - $(this).width();

        if( submenuPos > windowPos ){
            $(this).find('ul').offset({ "left": newPos });
        } else {
            $(this).find('ul').offset({ "left": oldPos });
        }
    });
});

because I don't want to add this fix on every menu items I created a new class on it. place the fixed-menu on the ul:

<ul class="dropdown-menu fixed-menu">

I hope this works out for you.

ps. little bug in safari and chrome, first hover will place it to mutch to the left will update this post if I fixed it.

It's best practice to use COPY instead of ADD when you're copying from the local file system to the image. Also, I'd recommend creating a sub-folder to place your content into. If nothing else, it keeps things tidy. Make sure you mark the script as executable using chmod.

Here, I am creating a scripts sub-folder to place my script into and run it from:

RUN mkdir -p /scripts
COPY script.sh /scripts
WORKDIR /scripts
RUN chmod +x script.sh

You can do it with a simple VLOOKUP formula. I've put the data in the same sheet, but you can also reference a different worksheet. For the price column just change the last value from 2 to 3, as you are referencing the third column of the matrix "A2:C4".

External Reference

To reference a cell of the same Workbook use the following pattern:

<Sheetname>!<Cell>

Example:

Table1!A1

To reference a cell of a different Workbook use this pattern:

[<Workbook_name>]<Sheetname>!<Cell>

Example:

[MyWorkbook]Table1!A1

Collection is the main interface of Java Collections hierarchy and List(Sequence) is one of the sub interfaces that defines an ordered collection.

No issues with the latest kartoza/qgis-desktop

I ran

docker pull kartoza/qgis-desktop

followed by

docker run -it --rm --name "qgis-desktop-2-4" -v ${HOME}:/home/${USER} -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY kartoza/qgis-desktop:latest

I did try multiple times without the conflict error - you do have to exit the app beforehand. Also, please note the parameters do differ slightly.

I know this is a super old post, but I think what is missed is overriding __repr__, so that __repr__ = __str__, which is the accepted answer of this question marked duplicate.

There is no way to declare a global variable in Transact-SQL. However, if all you want your variables for is to be accessible across batches of a single script, you can use the SQLCMD tool or the SQLCMD mode of SSMS and define that tool/mode-specific variables like this:

:setvar myvar 10

and then use them like this:

$(myvar)

To use SSMS's SQLCMD mode:

Follow the steps in the latest version of the documentation. Note: GPU and CPU functionality is now combined in a single tensorflow package

pip install tensorflow

# OLDER VERSIONS pip install tensorflow-gpu

This is a great guide for installing drivers and CUDA if needed: https://www.quantstart.com/articles/installing-tensorflow-22-on-ubuntu-1804-with-an-nvidia-gpu/

Try:

>>> t = ((1, 'a'),(2, 'b'))
>>> dict((y, x) for x, y in t)
{'a': 1, 'b': 2}

In unix (mac os X included) terminal you can do

which python

and it will tell you.

You can convert your number to string and use list slicing like this:

int(str(number)[:2])

Output:

>>> number = 1520
>>> int(str(number)[:2])
15

i have used this code given below

 CustomerType = ((EnumCustomerType)(cus.CustomerType)).ToString()

Or maybe:

names = ['Jasmine', 'Alberto', 'Ross', 'dig-dog']
print ("The solution for this is about this names being sorted:",sorted(names, key=lambda name:name.lower()))

i know this question is old, but hopefully it will help someone. i found a great plugin for those who are using PyCharm IDE: string-manipulation that can easily escape double quotes (and many more...), this plugin is great for cases where you know what the string going to be. for other cases, using json.dumps(string) will be the recommended solution

str_to_escape = 'my string with "double quotes" blablabla'

after_escape = 'my string with \"double quotes\" blablabla'

So, there are three parts. Reading, storing and sending.

Here's the reading part:

var fs = require('fs');

function readFiles(dirname, onFileContent, onError) {
  fs.readdir(dirname, function(err, filenames) {
    if (err) {
      onError(err);
      return;
    }
    filenames.forEach(function(filename) {
      fs.readFile(dirname + filename, 'utf-8', function(err, content) {
        if (err) {
          onError(err);
          return;
        }
        onFileContent(filename, content);
      });
    });
  });
}

Here's the storing part:

var data = {};
readFiles('dirname/', function(filename, content) {
  data[filename] = content;
}, function(err) {
  throw err;
});

The sending part is up to you. You may want to send them one by one or after reading completion.

If you want to send files after reading completion you should either use sync versions of fs functions or use promises. Async callbacks is not a good style.

Additionally you asked about stripping an extension. You should proceed with questions one by one. Nobody will write a complete solution just for you.

#include<stdio.h>
#define n 3
struct body
{
    double p[3];//position
    double v[3];//velocity
    double a[3];//acceleration
    double radius;
    double mass;
};

struct body bodies[n];

int main()
{
    int a, b;
     for(a = 0; a < n; a++)
     {
            for(b = 0; b < 3; b++)
            {
                bodies[a].p[b] = 0;
                bodies[a].v[b] = 0;
                bodies[a].a[b] = 0;
            }
            bodies[a].mass = 0;
            bodies[a].radius = 1.0;
     }

    return 0;
}

this works fine. your question was not very clear by the way, so match the layout of your source code with the above.

new File(absolutePath).getName();

remap is an option that makes mappings work recursively. By default it is on and I'd recommend you leave it that way. The rest are mapping commands, described below:

:map and :noremap are recursive and non-recursive versions of the various mapping commands. For example, if we run:

:map j gg           (moves cursor to first line)
:map Q j            (moves cursor to first line)
:noremap W j        (moves cursor down one line)

Then:

• j will be mapped to gg.
• Q will also be mapped to gg, because j will be expanded for the recursive mapping.
• W will be mapped to j (and not to gg) because j will not be expanded for the non-recursive mapping.

Now remember that Vim is a modal editor. It has a normal mode, visual mode and other modes.

For each of these sets of mappings, there is a mapping that works in normal, visual, select and operator modes (:map and :noremap), one that works in normal mode (:nmap and :nnoremap), one in visual mode (:vmap and :vnoremap) and so on.

For more guidance on this, see:

:help :map
:help :noremap
:help recursive_mapping
:help :map-modes

The issue is because you have a bean of type SuggestionService created through @Component annotation and also through the XML config . As explained by JB Nizet, this will lead to the creation of a bean with name 'suggestionService' created via @Component and another with name 'SuggestionService' created through XML .

When you refer SuggestionService by @Autowired, in your controller, Spring autowires "by type" by default and find two beans of type 'SuggestionService'

You could do the following

1. Remove @Component from your Service and depend on mapping via XML - Easiest

2. Remove SuggestionService from XML and autowire the dependencies - use util:map to inject the indexSearchers map.

3. Use @Resource instead of @Autowired to pick the bean by its name .

    @Resource(name="suggestionService")
    private SuggestionService service;
   

or

    @Resource(name="SuggestionService")
    private SuggestionService service;

both should work.The third is a dirty fix and it's best to resolve the bean conflict through other ways.

just .idea/ works fine for me

Just a little bug (Bug for me) I found on mac emulator.

On changing the orientation to landscape (CtrlCmdF11) it changes to landscape but content shows in portrait format.for that:

Go to emulator: Settings-> Display->When device is rotated->Rotate the contents of the screen

Or you could go the regex route:

String date = "10/07/2010";
String newDate = date.replaceAll("(\\d+)/(\\d+)/(\\d+)", "$3/$2/$1");
System.out.println(newDate);

It works both ways too. Of course this won't actually validate your date and will also work for strings like "21432/32423/52352". You can use "(\\d{2})/(\\d{2})/(\\d{4}" to be more exact in the number of digits in each group, but it will only work from dd/MM/yyyy to yyyy/MM/dd and not the other way around anymore (and still accepts invalid numbers in there like 45). And if you give it something invalid like "blabla" it will just return the same thing back.

This is really old, but I wanted to add my slight variation for anyone else who may stumble across this. Regular expressions are powerful things.

To keep the text which falls between the equal sign and the comma:

-replace "^.*?=(.*?),.*?$",'$1'

This regular expression starts at the beginning of the line, wipes all characters until the first equal sign, captures every character until the next comma, then wipes every character until the end of the line. It then replaces the entire line with the capture group (anything within the parentheses). It will match any line that contains at least one equal sign followed by at least one comma. It is similar to the suggestion by Trix, but unlike that suggestion, this will not match lines which only contain either an equal sign or a comma, it must have both in order.

I had this error and was explicitly setting the blocksize: aesManaged.BlockSize = 128;

Once I removed that, it worked.

According to the book PHP and MySQL for Dynamic Web Sites (4th edition)

Example:

$r = mysqli_query($dbc, $q);

For simple queries like INSERT, UPDATE, DELETE, etc. (which do not return records), the $r variable—short for result—will be either TRUE or FALSE, depending upon whether the query executed successfully.

Keep in mind that “executed successfully” means that it ran without error; it doesn’t mean that the query’s execution necessarily had the desired result; you’ll need to test for that.

Then how to test?

While the mysqli_num_rows() function will return the number of rows generated by a SELECT query, mysqli_affected_rows() returns the number of rows affected by an INSERT, UPDATE, or DELETE query. It’s used like so:

$num = mysqli_affected_rows($dbc);

Unlike mysqli_num_rows(), the one argument the function takes is the database connection ($dbc), not the results of the previous query ($r).

You need to call p.Start() to actually run the process after you set the StartInfo. As it is, your function is probably hanging on the WaitForExit() call because the process was never actually started.

SWIFT 2 UPDATE

Here's how to find out which button was tapped + send data to another ViewController from that button's indexPath.row as I'm assuming that's the point for most!

@IBAction func yourButton(sender: AnyObject) {


     var position: CGPoint = sender.convertPoint(CGPointZero, toView: self.tableView)
        let indexPath = self.tableView.indexPathForRowAtPoint(position)
        let cell: UITableViewCell = tableView.cellForRowAtIndexPath(indexPath!)! as
        UITableViewCell
        print(indexPath?.row)
        print("Tap tap tap tap")

    }

For those who are using a ViewController class and added a tableView, I'm using a ViewController instead of a TableViewController so I manually added the tableView in order to access it.

Here is the code for passing data to another VC when tapping that button and passing the cell's indexPath.row

@IBAction func moreInfo(sender: AnyObject) {

    let yourOtherVC = self.storyboard!.instantiateViewControllerWithIdentifier("yourOtherVC") as! YourOtherVCVIewController



    var position: CGPoint = sender.convertPoint(CGPointZero, toView: self.tableView)
    let indexPath = self.tableView.indexPathForRowAtPoint(position)
    let cell: UITableViewCell = tableView.cellForRowAtIndexPath(indexPath!)! as
    UITableViewCell
    print(indexPath?.row)
    print("Button tapped")


    yourOtherVC.yourVarName = [self.otherVCVariable[indexPath!.row]]

    self.presentViewController(yourNewVC, animated: true, completion: nil)

}

Oddly enough, the issue for me was I was trying to open 2012 SQL Server Integration Services on SSMS 2008 R2. When I opened the same in SSMS 2012, it connected right away.

Use os.path.abspath():

os.chdir(os.path.dirname(os.path.abspath(sys.argv[0])))

sys.argv[0] in your case is just a script name, no directory, so os.path.dirname() returns an empty string.

os.path.abspath() turns that into a proper absolute path with directory name.

Also, there is an awesome open-source pure-python distributed and scaleable locust framework that uses greenlets. It's great at simulating enormous amount of simultaneous users.

There is now a "native" solution on Windows 10, after enabling Bash on Windows, you can enter Bash shell by typing bash:

You can run Bash script like bash ./script.sh, but keep in mind that C drive is located at /mnt/c, and external hard drives are not mountable. So you might need to change your script a bit so it is compatible to Windows.

Also, even as root, you can still get permission denied when moving files around in /mnt, but you have your full root power in the / file system.

Also make sure your shell script is formatted with Unix style, or there can be errors.

Do not hardcode path like //data/data/<Your-Application-Package-Name>/databases/<your-database-name>. Well it does work in most cases, but this one is not working in devices where device can support multiple users. The path can be like //data/user/10/<Your-Application-Package-Name>/databases/<your-database-name>. Possible solution to this is using context.getDatabasePath(<your-database-name>).

Using array.filter() We can get an array of objects which will match with our condition.
see the working example.

Using extract-css-chunks-webpack-plugin and css-loader loader work for me, see below:

webpack.config.js Import extract-css-chunks-webpack-plugin

const ExtractCssChunks = require('extract-css-chunks-webpack-plugin');

webpack.config.js Add the css rule, Extract css Chunks first then the css loader css-loader will embed them into the html document, ensure css-loader and extract-css-chunks-webpack-plugin are in the package.json dev dependencies

rules: [
      {
        test: /\.css$/,
        use: [
          {
            loader: ExtractCssChunks.loader,
          },
          'css-loader',
        ],
      }
]

webpack.config.js Make instance of the plugin

plugins: [
    new ExtractCssChunks({
      // Options similar to the same options in webpackOptions.output
      // both options are optional
      filename: '[name].css',
      chunkFilename: '[id].css'
    })
  ]

And now importing css is possible And now in a tsx file like index.tsx i can use import like this import './Tree.css' where Tree.css contains css rules like

body {
    background: red;
}

My app is using typescript and this works for me, check my repo for the source : https://github.com/nickjohngray/staticbackeditor

So let's say after getMasterData servlet will response.sendRedirect to to test.jsp.

In test.jsp

Create a javascript

<script type="text/javascript">
function alertName(){
alert("Form has been submitted");
} 
</script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

Note:im not sure how to type the code in stackoverflow!. Edit: I just learned how to

Edit 2: TO the question:This works perfectly. Another question. How would I get rid of the initial alert when I first start up the JSP? "Form has been submitted" is present the second I execute. It shows up after the load is done to which is perfect.

To do that i would highly recommendation to use session!

So what you want to do is in your servlet:

session.setAttribute("getAlert", "Yes");//Just initialize a random variable.
response.sendRedirect(test.jsp);

than in the test.jsp

<%
session.setMaxInactiveInterval(2);
%>

 <script type="text/javascript">
var Msg ='<%=session.getAttribute("getAlert")%>';
    if (Msg != "null") {
 function alertName(){
 alert("Form has been submitted");
 } 
 }
 </script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

So everytime you submit that form a session will be pass on! If session is not null the function will run!

return; will exit a method in C#.

See code snippet below

using System;

namespace Exercise_strings
{
    class Program
    {
        static void Main(string[] args)
        {
           Console.WriteLine("Input string separated by -");

            var stringInput = Console.ReadLine();

            if (string.IsNullOrWhiteSpace(stringInput))
            {
                Console.WriteLine("Nothing entered");
                return;
            }
}

So in this case if a user enters a null string or whitespace, the use of the return method terminates the Main method elegantly.

From http://social.msdn.microsoft.com/Forums/vstudio/en-US/12ead5d4-1d57-4dbb-ba81-bc13084ba370/how-can-i-add-a-line-as-a-visual-separator-to-the-content-control-like-grid?forum=wpf:

Try this example and see if it fits your needs, there are three main aspects to it.

1. Line.Stretch is set to fill.

2. For horizontal lines the VerticalAlignment of the line is set Bottom, and for VerticalLines the HorizontalAlignment is set to Right.

3. We then need to tell the line how many rows or columns to span, this is done by binding to either RowDefinitions or ColumnDefintions count property.

The short answer is that not only is static useful, it is pretty well always going to be desired.

First, note that static and constexpr are completely independent of each other. static defines the object's lifetime during execution; constexpr specifies that the object should be available during compilation. Compilation and execution are disjoint and discontiguous, both in time and space. So once the program is compiled, constexpr is no longer relevant.

Every variable declared constexpr is implicitly const but const and static are almost orthogonal (except for the interaction with static const integers.)

The C++ object model (§1.9) requires that all objects other than bit-fields occupy at least one byte of memory and have addresses; furthermore all such objects observable in a program at a given moment must have distinct addresses (paragraph 6). This does not quite require the compiler to create a new array on the stack for every invocation of a function with a local non-static const array, because the compiler could take refuge in the as-if principle provided it can prove that no other such object can be observed.

That's not going to be easy to prove, unfortunately, unless the function is trivial (for example, it does not call any other function whose body is not visible within the translation unit) because arrays, more or less by definition, are addresses. So in most cases, the non-static const(expr) array will have to be recreated on the stack at every invocation, which defeats the point of being able to compute it at compile time.

On the other hand, a local static const object is shared by all observers, and furthermore may be initialized even if the function it is defined in is never called. So none of the above applies, and a compiler is free not only to generate only a single instance of it; it is free to generate a single instance of it in read-only storage.

So you should definitely use static constexpr in your example.

However, there is one case where you wouldn't want to use static constexpr. Unless a constexpr declared object is either ODR-used or declared static, the compiler is free to not include it at all. That's pretty useful, because it allows the use of compile-time temporary constexpr arrays without polluting the compiled program with unnecessary bytes. In that case, you would clearly not want to use static, since static is likely to force the object to exist at runtime.

Here is another example which is working

And of course include these permission in manifest:

One of the most common errors that I found developing Android Apps is the “java.lang.OutOfMemoryError: Bitmap Size Exceeds VM Budget” error. I found this error frequently on activities using lots of bitmaps after changing orientation: the Activity is destroyed, created again and the layouts are “inflated” from the XML consuming the VM memory available for bitmaps.

Bitmaps on the previous activity layout are not properly de-allocated by the garbage collector because they have crossed references to their activity. After many experiments I found a quite good solution for this problem.

First, set the “id” attribute on the parent view of your XML layout:

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:id="@+id/RootView"
     >
     ...

Then, on the onDestroy() method of your Activity, call the unbindDrawables() method passing a reference to the parent View and then do a System.gc().

    @Override
    protected void onDestroy() {
    super.onDestroy();

    unbindDrawables(findViewById(R.id.RootView));
    System.gc();
    }

    private void unbindDrawables(View view) {
        if (view.getBackground() != null) {
        view.getBackground().setCallback(null);
        }
        if (view instanceof ViewGroup) {
            for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
            unbindDrawables(((ViewGroup) view).getChildAt(i));
            }
        ((ViewGroup) view).removeAllViews();
        }
    }

This unbindDrawables() method explores the view tree recursively and:

1. Removes callbacks on all the background drawables
2. Removes children on every viewgroup

instead of creating too many complicated functions and methods what I do is I create an event listener and automatically have mount and unmount done for me without having to worry about doing it manually. Here is an example.

//componentDidMount
useEffect( () => {

    window.addEventListener("load",  pageLoad);

    //component will unmount
    return () => {
       
        window.removeEventListener("load", pageLoad);
    }

 });

now that this part is done I just run anything I want from the pageLoad function like this.

const pageLoad = () =>{
console.log(I was mounted and unmounted automatically :D)}

Found the answer. In the file xampp\apache\conf\extra\httpd-ssl.conf, under the comment SSL Virtual Host Context pages on port 443 meaning https is looked up under different document root.

Simply change the document root to the same one and problem is fixed.

If this is part of a batch script (.bat file) and you have a large list of files, you can use a multi-line ^, and optional /Y flag to suppresses prompting to confirm you want to overwrite an existing destination file.

REM Concatenate several files to one
COPY /Y ^
    this_is_file_1.csv + ^
    this_is_file_2.csv + ^
    this_is_file_3.csv + ^
    this_is_file_4.csv + ^
    this_is_file_5.csv + ^
    this_is_file_6.csv + ^
    this_is_file_7.csv + ^
    this_is_file_8.csv + ^
    this_is_file_9.csv ^
        output_file.csv

This is tidier than performing the command on one line.

This works:

$category = $catrep->createQueryBuilder('cc')
        ->select('cc.categoryid')
        ->where('cc.contenttype = :type')
        ->setParameter('type', 'blogarticle')
        ->distinct()
        ->getQuery();

$categories = $category->getResult();

Edit for Symfony 3 & 4.

You should use ->groupBy('cc.categoryid') instead of ->distinct()

max is a builtin function in python, which is used to get max value from a sequence, i.e (list, tuple, set, etc..)

print(max([9, 7, 12, 5]))

# prints 12 

I use in my batch files - c:\progra~2\ instead of C:\Program Files (x86)\ and it works.

Check your route for the function in which you are using Auth::user(), For getting Auth::user() data the function should be inside web middleware Route::group(['middleware' => 'web'], function () {}); .

You must create your own SSLSocketFactory based on Bouncy Castle. After to use it, pass to the common HttpsConnextion for using this customized SocketFactory.

1. First : Create a TLSConnectionFactory

Here one tips:

1.1 Extend SSLConnectionFactory

1.2 Override this method :

@Override 
public Socket createSocket(Socket socket, final String host, int port, boolean arg3)

This method will call the next internal method,

1.3 Implement an internal method _createSSLSocket(host, tlsClientProtocol);

Here you must create a Socket using TlsClientProtocol . The trick is override ...startHandshake() method calling TlsClientProtocol

 private SSLSocket _createSSLSocket(final String host , final TlsClientProtocol tlsClientProtocol) {
     return new SSLSocket() {    
       .... Override and implement SSLSocket methods,  particulary: 
            startHandshake() {
             }    
     }

     

Important : The full sample how to use TLS Client Protocol is well explained here: Using BouncyCastle for a simple HTTPS query

2. Second : Use this Customized SSLConnextionFactory on common HTTPSConnection.

This is important ! In other samples you can see into the web , u see hard-coded HTTP Commands....so with a customized SSLConnectionFactory u don't need nothing more...

  URL myurl = new URL( "http:// ...URL tha only Works in TLS 1.2);
  HttpsURLConnection  con = (HttpsURLConnection )myurl.openConnection();
  con.setSSLSocketFactory(new TSLSocketConnectionFactory());

In Windows I had to create the environment variable HOME pointing to my user profile first (C:\Users\<name>) or whatever directory you prefer.

Then start a new command line window, create a a .ssh directory in your user profile or choosen diretory using mkdir ".ssh" command.

After doing that I was able to use the ssh-keygen without any path problems.

Casting is necessary to tell that you are calling a child and not a parent method. So it's ever downward. However if the method is already defined in the parent class and overriden in the child class, you don't any cast. Here an example:

class Parent{
   void method(){ System.out.print("this is the parent"); }
}

class Child extends Parent{
   @override
   void method(){ System.out.print("this is the child"); }
}
...
Parent o = new Child();
o.method();
((Child)o).method();  

The two method call will both print : "this is the child".

It didn't work for me when I used

http://localhost{port}/
http://localhost:{port}/something-else/here

However, removing the http did the trick for me. I just added localhost:8000 without prefixing it with the http.

I remember JavaScript Closures when I See this.. Here is how i do it..

        function Increment() {
            var num = 0; // Here num is a private static variable
            return function () {
                return ++num;
            }
        }

        var inc = new Increment();
        console.log(inc());//Prints 1
        console.log(inc());//Prints 2
        console.log(inc());//Prints 3

This behavior is expected. flex container will stretch all its children by default. Image have no exception. (ie, parent will have align-items: stretch property )

To keep the aspect ratio we've two solutions:

1. Either replace default align-items: stretch property to align-items: flex-start or align-self: center etc, http://jsfiddle.net/e394Lqnt/3/

or

2. Set align property exclusively to the child itself: like, align-self: center or align-self: flex-start etc. http://jsfiddle.net/e394Lqnt/2/

I thought you might forget to add attribute data-toggle="modal" to the link or button that triggers the modal popup event. Firstly, I also got the same problem but, after adding the attribute above it works well for me.

I think you've actually got a wider confusion here.

The initial error is that you're trying to call split on the whole list of lines, and you can't split a list of strings, only a string. So, you need to split each line, not the whole thing.

And then you're doing for points in Type, and expecting each such points to give you a new x and y. But that isn't going to happen. Types is just two values, x and y, so first points will be x, and then points will be y, and then you'll be done. So, again, you need to loop over each line and get the x and y values from each line, not loop over a single Types from a single line.

So, everything has to go inside a loop over every line in the file, and do the split into x and y once for each line. Like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")

    for line in readfile:
        Type = line.split(",")
        x = Type[1]
        y = Type[2]
        print(x,y)

getQuakeData()

As a side note, you really should close the file, ideally with a with statement, but I'll get to that at the end.

Interestingly, the problem here isn't that you're being too much of a newbie, but that you're trying to solve the problem in the same abstract way an expert would, and just don't know the details yet. This is completely doable; you just have to be explicit about mapping the functionality, rather than just doing it implicitly. Something like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")
    readlines = readfile.readlines()
    Types = [line.split(",") for line in readlines]
    xs = [Type[1] for Type in Types]
    ys = [Type[2] for Type in Types]
    for x, y in zip(xs, ys):
        print(x,y)

getQuakeData()

Or, a better way to write that might be:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    # Use with to make sure the file gets closed
    with open(filename, "r") as readfile:
        # no need for readlines; the file is already an iterable of lines
        # also, using generator expressions means no extra copies
        types = (line.split(",") for line in readfile)
        # iterate tuples, instead of two separate iterables, so no need for zip
        xys = ((type[1], type[2]) for type in types)
        for x, y in xys:
            print(x,y)

getQuakeData()

Finally, you may want to take a look at NumPy and Pandas, libraries which do give you a way to implicitly map functionality over a whole array or frame of data almost the same way you were trying to.

The easiest would be to use a regular expression with g flag to replace all instances:

str.replace(/foo/g, "bar")

This will replace all occurrences of foo with bar in the string str. If you just have a string, you can convert it to a RegExp object like this:

var pattern = "foobar",
    re = new RegExp(pattern, "g");

As mentioned here: Re: BUG #4243: Idle in transaction it is probably best to check your pg_locks table to see what is being locked and that might give you a better clue where the problem lies.

The height of a block element defaults to the height of the block's content. So, given something like this:

<div id="outer">
    <div id="inner">
        <p>Where is pancakes house?</p>
    </div>
</div>

#inner will grow to be tall enough to contain the paragraph and #outer will grow to be tall enough to contain #inner.

When you specify the height or width as a percentage, that's a percentage with respect to the element's parent. In the case of width, all block elements are, unless specified otherwise, as wide as their parent all the way back up to <html>; so, the width of a block element is independent of its content and saying width: 50% yields a well defined number of pixels.

However, the height of a block element depends on its content unless you specify a specific height. So there is feedback between the parent and child where height is concerned and saying height: 50% doesn't yield a well defined value unless you break the feedback loop by giving the parent element a specific height.

The onMessageReceived method is fired only when app is in foreground or the notification payload only contains the data type.

From the Firebase docs

For downstream messaging, FCM provides two types of payload: notification and data.

For notification type, FCM automatically displays the message to end-user devices on behalf of the client app. Notifications have a predefined set of user-visible keys.
For data type, client app is responsible for processing data messages. Data messages have only custom key-value pairs.

Use notifications when you want FCM to handle displaying a notification on your client app's behalf. Use data messages when you want your app to handle the display or process the messages on your Android client app, or if you want to send messages to iOS devices when there is a direct FCM connection.

Further down the docs

App behaviour when receiving messages that include both notification and data payloads depends on whether the app is in the background or the foreground—essentially, whether or not it is active at the time of receipt.
When in the background, apps receive the notification payload in the notification tray, and only handle the data payload when the user taps on the notification.
When in the foreground, your app receives a message object with both payloads available.

If you are using the firebase console to send notifications, the payload will always contain the notification type. You have to use the Firebase API to send the notification with only the data type in the notification payload. That way your app is always notified when a new notification is received and the app can handle the notification payload.

If you want to play notification sound when app is in background using the conventional method, you need to add the sound parameter to the notification payload.

I just had to update an .edmx model. The model/Run Custom Tool option was not refreshing the fields for me, but once I had the graphical designer open, I was able to manually rename the fields.

I know this is an old question but I just want to comment here: To any extent email addresses ARE case sensitive, most users would be "very unwise" to actively use an email address that requires capitals. They would soon stop using the address because they'd be missing a lot of their mail. (Unless they have a specific reason to make things difficult, and they expect mail only from specific senders they know.)

That's because imperfect humans as well as imperfect software exist, (Surprise!) which will assume all email is lowercase, and for this reason these humans and software will send messages using a "lower cased version" of the address regardless of how it was provided to them. If the recipient is unable to receive such messages, it won't be long before they notice they're missing a lot, and switch to a lowercase-only email address, or get their server set up to be case-insensitive.

The format method was introduced in Python 2.6. It is more capable and not much more difficult to use:

>>> "Hello {}, my name is {}".format('john', 'mike')
'Hello john, my name is mike'.

>>> "{1}, {0}".format('world', 'Hello')
'Hello, world'

>>> "{greeting}, {}".format('world', greeting='Hello')
'Hello, world'

>>> '%s' % name
"{'s1': 'hello', 's2': 'sibal'}"
>>> '%s' %name['s1']
'hello'

An alternative to BouncyCastle for AES-GCM encryption is libsodium-net. It wraps the libsodium C library. One nice advantage is that it uses the AES-NI extension in CPUs for very fast encryption. The down side is that it won't work at all if the CPU doesn't have the extension. There's no software fall back.

You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.

Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).

EDIT:

Here is some code:

For the UDF:

    Public Function UDF_Date(ByVal data) As Date

        UDF_Date = Now()

    End Function

As Formula in D2:

=UDF_Date(C2)

You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.

And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.

Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.

Addendum:

Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:

• The usage of the UDF is the same as described above.

• The UDF works only for single cell input ranges.

• The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.

• If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.

• The code might brake for cell-values for which conversion to string is non-deterministic.

• The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.

  Public Function UDF_Date(ByVal inData As Range) As Date
  
      Dim wb As Workbook
      Dim dProps As DocumentProperties
      Dim pValue As DocumentProperty
      Dim pDate As DocumentProperty
      Dim sName As String
      Dim sNameDate As String
  
      Dim bDate As Boolean
      Dim bValue As Boolean
      Dim bChanged As Boolean
  
      bDate = True
      bValue = True
  
      bChanged = False
  
  
      Dim sVal As String
      Dim dDate As Date
  
      sName = inData.Address & "_" & inData.Worksheet.Name
      sNameDate = sName & "_dat"
  
      sVal = CStr(inData.Value)
      dDate = Now()
  
      Set wb = inData.Worksheet.Parent
  
      Set dProps = wb.CustomDocumentProperties
  
  On Error Resume Next
  
      Set pValue = dProps.Item(sName)
  
      If Err.Number <> 0 Then
          bValue = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bValue Then
          bChanged = True
          Set pValue = dProps.Add(sName, False, msoPropertyTypeString, sVal)
      Else
          bChanged = pValue.Value <> sVal
          If bChanged Then
              pValue.Value = sVal
          End If
      End If
  
  On Error Resume Next
  
      Set pDate = dProps.Item(sNameDate)
  
      If Err.Number <> 0 Then
          bDate = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bDate Then
          Set pDate = dProps.Add(sNameDate, False, msoPropertyTypeDate, dDate)
      End If
  
      If bChanged Then
          pDate.Value = dDate
      Else
          dDate = pDate.Value
      End If
  
  
      UDF_Date = dDate
   End Function
  

Make the insertion of the date conditional upon the range.

This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

Adapted from this tip and @Paul S answer

Private Sub Worksheet_Change(ByVal Target As Range)
 Dim R1 As Range
 Dim R2 As Range
 Dim InRange As Boolean
    Set R1 = Range(Target.Address)
    Set R2 = Range("C2:C20")
    Set InterSectRange = Application.Intersect(R1, R2)

  InRange = Not InterSectRange Is Nothing
     Set InterSectRange = Nothing
   If InRange = True Then
     R1.Offset(0, 1).Value = Now()
   End If
     Set R1 = Nothing
     Set R2 = Nothing
 End Sub

I would just use this small extension to Date - http://blog.stevenlevithan.com/archives/date-time-format

var date = new Date(msSinceEpoch);
date.format("isoDateTime"); // 2007-06-09T17:46:21

var ids = [];

    $(document).ready(function($) {    
    $(".color_cell").bind('click', function() {
        alert('Test');

        ids.push(this.id);       
    });
});

'Date' is your index so you want to do,

print (df.index.min())
print (df.index.max())

2014-03-13 00:00:00
2014-03-31 00:00:00

You can use:

Process proc = Process.GetCurrentProcess();

To get the current process and use:

proc.PrivateMemorySize64;

To get the private memory usage. For more information look at this link.

You should look at the shelve and pickle modules. If you need to store a lot of data it may be better to use a database

I've been in a situation like you (JPA/Hibernate sequence for non @Id field) and I ended up creating a trigger in my db schema that add a unique sequence number on insert. I just never got it to work with JPA/Hibernate

@jstn's answer is good, but a bit verbose. Swift is known as a protocol-oriented language, so we can achieve the same result without having to implement boilerplate code for every class in the integer family, by adding a default implementation for the protocol extension.

public extension ExpressibleByIntegerLiteral {
    public static func arc4random() -> Self {
        var r: Self = 0
        arc4random_buf(&r, MemoryLayout<Self>.size)
        return r
    }
}

Now we can do:

let i = Int.arc4random()
let j = UInt32.arc4random()

and all other integer classes are ok.

You're in luck bud...I had the same issue but had more tech knowledge on the matter and was able to determine that it was a mod_sec issue that hostgator has to fix/whitelist on their own. You cannot do it yourself. Simply ask the hostgator tech to check mod_sec settings on your server.

Enjoy your fixed issue ;D

after that all html we want to write these lines of code

<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script>

On Excel 2010 try this:

1. select the cell you want to check if is used somewhere in a formula;
2. Formulas -> Trace Dependents (on Formula Auditing menu)

I haven't any personal experience with either of the following, but a simple search for a "Python [memory] profiler" yield:

• PySizer, "a memory profiler for Python," found at http://pysizer.8325.org/. However the page seems to indicate that the project hasn't been updated for a while, and refers to...

• Heapy, "support[ing] debugging and optimization regarding memory related issues in Python programs," found at http://guppy-pe.sourceforge.net/#Heapy.

Hope that helps.

I'm sure this isn't as fast as the solutions using Pandas or Numpy operations, but if you don't want to rewrite your function you can use map. Using the original example data -

import pandas as pd

df = pd.DataFrame({'ID':['1','2','3'], 'col_1': [0,2,3], 'col_2':[1,4,5]})
mylist = ['a','b','c','d','e','f']

def get_sublist(sta,end):
    return mylist[sta:end+1]

df['col_3'] = list(map(get_sublist,df['col_1'],df['col_2']))
#In Python 2 don't convert above to list

We could pass as many arguments as we wanted into the function this way. The output is what we wanted

ID  col_1  col_2      col_3
0  1      0      1     [a, b]
1  2      2      4  [c, d, e]
2  3      3      5  [d, e, f]

Try the following code:

moment(startDate).startOf('months')
moment(startDate).endOf('months')

For completeness, it's worth mentioning there's a decent handling of empty collections in Freemarker since recently.

So the most convenient way to iterate a map is:

<#list tags>
<ul class="posts">
    <#items as tagName, tagCount>
        <li>{$tagName} (${tagCount})</li>
    </#items>
</ul>
<#else>
    <p>No tags found.</p>
</#list>

No more <#if ...> wrappers.

The folder is part of the URL you set when you create request: "ftp://www.contoso.com/test.htm". If you use "ftp://www.contoso.com/wibble/test.htm" then the file will be uploaded to a folder named wibble.

You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory to make the wibble folder if it doesn't already exist.

I suggest to add the '+' operator as follows:

list = list + ['foo']

Hope it helps!

I had this error but could not figure out the solution based on this thread but solved it myself.

For my problem I was compiling this code:

package valentines;

import java.math.BigInteger;
import java.util.ArrayList;

public class StudentSolver {
    public static ArrayList<Boolean> solve(ArrayList<ArrayList<BigInteger>> problems) {
        //DOING WORK HERE
        
    }
    public static void main(String[] args){
        //TESTING SOLVE FUNCTION
    }
    
}

I was then compiling this code in a folder structure that was like /ProjectName/valentines Compiling it worked fine but trying to execute: java StudentSolver

I was getting the NoClassDefError.

To fix this I simply removed: package valentines;

I'm not very well versed in java packages and such but this how I fixed my error so sorry if this was already answered by someone else but I couldn't interpret it to my problem.

Using org.apache.commons.lang3.StringUtils.join(*) methods can be an option
For example:

String[] strArray = new String[] { "John", "Mary", "Bob" };
String arrayAsCSV = StringUtils.join(strArray, " , ");
System.out.printf("[%s]", arrayAsCSV);
//output: [John , Mary , Bob]

I used the following dependency

<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.3.2</version>

Use aggregation on name and get name with count > 1:

db.collection.aggregate([
    {"$group" : { "_id": "$name", "count": { "$sum": 1 } } },
    {"$match": {"_id" :{ "$ne" : null } , "count" : {"$gt": 1} } }, 
    {"$project": {"name" : "$_id", "_id" : 0} }
]);

To sort the results by most to least duplicates:

db.collection.aggregate([
    {"$group" : { "_id": "$name", "count": { "$sum": 1 } } },
    {"$match": {"_id" :{ "$ne" : null } , "count" : {"$gt": 1} } }, 
    {"$sort": {"count" : -1} },
    {"$project": {"name" : "$_id", "_id" : 0} }     
]);

To use with another column name than "name", change "$name" to "$column_name"

For PHP 5 >= 5.3.0 http://www.php.net/manual/en/datetime.createfromformat.php

$datetime = "20130409163705"; 
$d = DateTime::createFromFormat("YmdHis", $datetime);
echo $d->format("d/m/Y H:i:s"); // or any you want

Result:

09/04/2013 16:37:05

Both are supported. To quote the Arduino homepage,

The core libraries are written in C and C++ and compiled using avr-gcc

Note that C++ is a superset of C (well, almost), and thus can often look very similar. I am not an expert, but I guess that most of what you will program for the Arduino in your first year on that platform will not need anything but plain C.

SimpleDateFormat dateFormat = new SimpleDateFormat( "yyyy-MM-dd" );
Calendar cal = Calendar.getInstance();
cal.setTime( dateFormat.parse( inputString ) );
cal.add( Calendar.DATE, 1 );

You can do one thing.

1. In the AppSettings.config (create one if doesn't exist), create a key value pair.
2. In the Code pull the value and convert it to Int32 and assign it to command.TimeOut.

like:- In appsettings.config ->

<appSettings>    
   <add key="SqlCommandTimeOut" value="240"/>
</appSettings>

In Code ->

command.CommandTimeout = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SqlCommandTimeOut"]);

That should do it.

Note:- I faced most of the timeout issues when I used SqlHelper class from microsoft application blocks. If you have it in your code and are facing timeout problems its better you use sqlcommand and set its timeout as described above. For all other scenarios sqlhelper should do fine. If your client is ok with waiting a little longer than what sqlhelper class offers you can go ahead and use the above technique.

example:- Use this -

 SqlCommand cmd = new SqlCommand(completequery);

 cmd.CommandTimeout =  Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SqlCommandTimeOut"]);

 SqlConnection con = new SqlConnection(sqlConnectionString);
 SqlDataAdapter adapter = new SqlDataAdapter();
 con.Open();
 adapter.SelectCommand = new SqlCommand(completequery, con);
 adapter.Fill(ds);
 con.Close();

Instead of

DataSet ds = new DataSet();
ds = SqlHelper.ExecuteDataset(sqlConnectionString, CommandType.Text, completequery);

Update: Also refer to @Triynko answer below. It is important to check that too.

PrincipalContext pc1 = new PrincipalContext(ContextType.Domain, "DomainName", UserAccountOU, UserName, Password);
UserPrincipal UserPrincipalID = UserPrincipal.FindByIdentity(pc1, IdentityType.SamAccountName, UserID);

searcher.Filter = "(&(ObjectClass=group)(member = " + UserPrincipalID.DistinguishedName + "));

I had the similar issue, 0.0% coverage & no unit tests count on Sonar dashboard with SonarQube 6.7.2: Maven : 3.5.2, Java : 1.8, Jacoco : Worked with 7.0/7.9/8.0, OS : Windows

After a lot of struggle finding for correct solution on maven multi-module project,not like single module project here we need to say to pick jacoco reports from individual modules & merge to one report,So resolved issue with this configuration as my parent pom looks like:

I've tried few other options like jacoco-aggregate & even creating a sub-module by including that in parent pom but nothing really worked & this is simple. I see in logs <sonar.jacoco.reportPath> is deprecated,but still works as is and seems like auto replaced on execution or can be manually updated to <sonar.jacoco.reportPaths> or latest. Once after doing setup in cmd start with mvn clean install then mvn org.jacoco:jacoco-maven-plugin:prepare-agent install (Check on project's target folder whether jacoco.exec is created) & then do mvn sonar:sonar , this is what I've tried please let me know if some other best possible solution available.Hope this helps!! If not please post your question..

You can use !, but you must have the ENABLEDELAYEDEXPANSION switch set.

setlocal ENABLEDELAYEDEXPANSION
set word=table
set str="jump over the chair"
set str=%str:chair=!word!%

First you need to determine the revision ID of the last known commit. You can use HEAD^ or HEAD~{1} if you know you need to reverse exactly one commit.

git reset --hard <revision_id_of_last_known_good_commit>
git push --force

Best css to fit space empty height:

@media print {
  body * {
    visibility: hidden;
    height:0;
  }
  #section-to-print, #section-to-print * {
    visibility: visible;
    height:auto;
  }
  #section-to-print {
    position: absolute;
    left: 0;
    top: 0;
  }
}

Just as an addition to answers that suggest to duplicate the columns and then to do cut. For duplication, paste etc. will work only for files, but not for streams. In that case, use sed instead.

cat file.txt | sed s/'.*'/'&\t&'/ | cut -f2,3

This works on both files and streams, and this is interesting if instead of just reading from a file with cat, you do something interesting before re-arranging the columns.

By comparison, the following does not work:

cat file.txt | paste - - | cut -f2,3

Here, the double stdin placeholder paste does not duplicate stdin, but reads the next line.

Another way if you must use cut command

ps axu | grep [j]boss |awk '$1=$1'|cut -d' ' -f5

In Solaris, replace awk with nawk or /usr/xpg4/bin/awk

Make a div and give it a class. Then drop a img in it.

<div class="mydiv">

<img src="location/of/your/image" ></img>

</div>

Set the size of your div and make it relative.

    .mydiv {
        position: relative;
        height:300px;
        width: 100%;
        overflow: hidden;
    }

then style your image

img {
    width: 100%;
    height: auto;
    overflow: hidden;
}

Hope that helps

Fix of this problem is add SVN directory(C:\Program Files\TortoiseSVN\bin) to Path system property

innerHTML is a string representing the contents of the element.

You want to modify the element itself. Drop the .innerHTML part.

This is the best way to make add images/screenshots of your app and keep your repository look clean.

Create a screenshot folder in your repository and add the images you want to display.

Now go to README.md and add this HTML code to form a table.

#### Flutter App Screenshots

<table>
  <tr>
    <td>First Screen Page</td>
     <td>Holiday Mention</td>
     <td>Present day in purple and selected day in pink</td>
  </tr>
  <tr>
    <td><img src="screenshots/Screenshot_1582745092.png" width=270 height=480></td>
    <td><img src="screenshots/Screenshot_1582745125.png" width=270 height=480></td>
    <td><img src="screenshots/Screenshot_1582745139.png" width=270 height=480></td>
  </tr>
 </table>

In the <td><img src="(COPY IMAGE PATH HERE)" width=270 height=480></td>

** To get the image path --> Go to the screenshot folder and open the image and on the right most side, you will find Copy path button.

You will get a table like this in your repository--->

The best way to do this is by running the command:

git diff --name-only --cached

When you check the manual you will likely find the following:

--name-only
    Show only names of changed files.

And on the example part of the manual:

git diff --cached
    Changes between the index and your current HEAD.

Combined together you get the changes between the index and your current HEAD and Show only names of changed files.

Update: --staged is also available as an alias for --cached above in more recent git versions.

str.lower() converts all cased characters to lowercase.

Given

• asyncFn function
• array of items

Required

• promise chaining .then()'s in series (in order)
• native es6

Solution

let asyncFn = (item) => {
  return new Promise((resolve, reject) => {
    setTimeout( () => {console.log(item); resolve(true)}, 1000 )
  })
}

// asyncFn('a')
// .then(()=>{return async('b')})
// .then(()=>{return async('c')})
// .then(()=>{return async('d')})

let a = ['a','b','c','d']

a.reduce((previous, current, index, array) => {
  return previous                                    // initiates the promise chain
  .then(()=>{return asyncFn(array[index])})      //adds .then() promise for each item
}, Promise.resolve())

There are many ways to create re-usable objects like this in JavaScript. Mozilla have a nice introduction here:

• https://developer.mozilla.org/en-US/docs/JavaScript/Introduction_to_Object-Oriented_JavaScript

The following will work in your example:

function Foo(){
    this.bar = function (){
        alert("Hello World!");
    }
}

myFoo = new Foo();
myFoo.bar(); // Hello World?????????????????????????????????

I also saw this change on my Mac when I went from running pip to sudo pip. Adding -H to sudo causes the message to go away for me. E.g.

sudo -H pip install foo

man sudo tells me that -H causes sudo to set $HOME to the target users (root in this case).

So it appears pip is looking into $HOME/Library/Log and sudo by default isn't setting $HOME to /root/. Not surprisingly ~/Library/Log is owned by you as a user rather than root.

I suspect this is some recent change in pip. I'll run it with sudo -H for now to work around.

The main difference between them you can find as follows:

HashSet

• It does not allow duplicate keys.
• Even it is not synchronized, so this will have better performance.
• It allows a null key.
• HashSet can be used when you want to maintain a unique list.
• HashSet implements Set interface and it is backed by the hash table(actually HashMap instance).
• HashSet stores objects.
• HashSet doesn’t allow duplicate elements but null values are allowed.
• This interface doesn’t guarantee that order will remain constant over time.

HashMap

• It allows duplicate keys. It is not synchronized, so this will have better performance.
• HashMap does not maintain insertion order.
• The order is defined by the Hash function.
• It is not Thread Safe
• It allows null for both key and value.
• It allows one null key and as many null values as you like.
• HashMap is a Hash table-based implementation of the Map interface.
• HashMap store object as key and value pair.
• HashMap does not allow duplicate keys but null keys and values are allowed.
• Ordering of the element is not guaranteed overtime.

Found this interesting approach when I wanted to implement enums in SQL Server.

The approach mentioned below in the link is quite compelling, considering all your database enum needs could be satisfied with 2 central tables.

http://blog.sqlauthority.com/2010/03/22/sql-server-enumerations-in-relational-database-best-practice/

I'm using Android Studio and gradle. It created the build/apk/<.apk> file only when I ran the project. Press the following to run your project: Alt+u, u

Android Studio: 0.5.3 Gradle: 0.9.+

thisReader.GetString(int columnIndex)

Use This:

Update Table Set Column = CAST(NULL As Column Type) where Condition

Like This:

Update News Set Title = CAST(NULL As nvarchar(100)) Where ID = 50

I was trying to do :

git rm -r *

but at the end for me works :

git rm -r .

I hope it helps to you.

I was up to date with everything and still got this error, not sure why but I think the image was corrupted in a strange way and after replacing the image I got rid of the error. Might be worth to try with a different image :)

JavaScript actually does support encapsulation, through a method that involves hiding members in closures (Crockford). That said, it's sometimes cumbersome, and the underscore convention is a pretty good convention to use for things that are sort of private, but that you don't actually need to hide.

throw is for rethrowing a caught exception. This can be useful if you want to do something with the exception before passing it up the call chain.

Using throw without any arguments preserves the call stack for debugging purposes.

I used the page-checkout.php template to change the header for my cart page. I renamed it to page-cart.php in my /wp-content/themes/childtheme/woocommerce/. This gives you more control over the wrapping html, header and footer.

There is the Math.pow(double a, double b) method. Note that it returns a double, you will have to cast it to an int like (int)Math.pow(double a, double b).

You may install your coinhsl library in one of your standard libraries directories and run 'ldconfig` before doing your ppyipopt install

Here is the documentation for backBarButtonItem:

"When this navigation item is immediately below the top item in the stack, the navigation controller derives the back button for the navigation bar from this navigation item. [...] If you want to specify a custom image or title for the back button, you can assign a custom bar button item (with your custom title or image) to this property instead."

View Controller A (the "parent" view controller):

self.title = @"Really Long Title";
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Short" style:UIBarButtonItemStyleBordered target:nil action:nil];
self.navigationItem.backBarButtonItem = backButton;

When any other view controller B is on top of the navigation stack, and A is right below it, B's back button will have the title "Short".

The problem was that my array was in type u3 i changed it to float and it worked for me . I had a dataframe with Image column having the image/pic data.Reshaping part depends to person to person and image they deal with mine had 9126 size hence it was 96*96.

a = np.array(df_train.iloc[0].Image.split(),dtype='float')
a = a.reshape(96,96)
plt.imshow(a)

It works for me:

$('#yourselect').on("change", function(e) { 
   // what you would like to happen
});

move in windows is equivalent of mv command in Linux

For some reason, even if changing the iOS Deployment Target to 8.0 or higher, the Xib files don't adopt that change and remain with the previous settings in the File inspector

Therefore, you should change it manually for each Xib

Once done, the warning will disappear :-)

I had the same problem with Python 3.5 on Ubuntu while using pyenv.

If you're installing the python using pyenv, it's listed as one of the common build problems. To solve it, remove the installed python version, install the requirements (for this particular case libsqlite3-dev), then reinstall the python version.

Live @Sergey's solution but with integer division.

double value = 23.8764367843;
double rounded = (double) Math.round(value * 100) / 100;
System.out.println(value +" rounded is "+ rounded);

prints

23.8764367843 rounded is 23.88

EDIT: As Sergey points out, there should be no difference between multipling double*int and double*double and dividing double/int and double/double. I can't find an example where the result is different. However on x86/x64 and other systems there is a specific machine code instruction for mixed double,int values which I believe the JVM uses.

for (int j = 0; j < 11; j++) {
    long start = System.nanoTime();
    for (double i = 1; i < 1e6; i *= 1.0000001) {
        double rounded = (double) Math.round(i * 100) / 100;
    }
    long time = System.nanoTime() - start;
    System.out.printf("double,int operations %,d%n", time);
}
for (int j = 0; j < 11; j++) {
    long start = System.nanoTime();
    for (double i = 1; i < 1e6; i *= 1.0000001) {
        double rounded = (double) Math.round(i * 100.0) / 100.0;
    }
    long time = System.nanoTime() - start;
    System.out.printf("double,double operations %,d%n", time);
}

Prints

You can create the headers on the fly (no need to specify delimiter when the delimiter is a comma):

Import-CSV $filepath -Header IP1,IP2,IP3,IP4 | Foreach-Object{
   Write-Host $_.IP1
   Write-Host $_.IP2
   ...
}

Remembering that the mean can also by obtained using a linear model, regressing the variable against a single intercept, you can use also the lm(x~1) function for this!

Advantages are:

• You obtain immediately confidence intervals with confint()
• You can use tests for various hypothesis about the mean, using for example car::linear.hypothesis()
• You can use more sophisticated estimates of the standard deviation, in case you have some heteroskedasticity, clustered-data, spatial-data etc, see package sandwich

## generate data
x <- rnorm(1000)

## estimate reg
reg <- lm(x~1)
coef(summary(reg))[,"Std. Error"]
#> [1] 0.03237811

## conpare with simple formula
all.equal(sd(x)/sqrt(length(x)),
          coef(summary(reg))[,"Std. Error"])
#> [1] TRUE

## extract confidence interval
confint(reg)
#>                   2.5 %    97.5 %
#> (Intercept) -0.06457031 0.0625035

It may be a bit pedantic / redundant with its numeric casting, but here's a safe function to calculate percentage of a given number:

function getPerc(num, percent) {
    return Number(num) - ((Number(percent) / 100) * Number(num));
}

// Usage: getPerc(10000, 25);

I noticed a posting that say that it does not matter if you call a __stdcall from a __cdecl or visa versa. It does.

The reason: with __cdecl the arguments that are passed to the called functions are removed form the stack by the calling function, in __stdcall, the arguments are removed from the stack by the called function. If you call a __cdecl function with a __stdcall, the stack is not cleaned up at all, so eventually when the __cdecl uses a stacked based reference for arguments or return address will use the old data at the current stack pointer. If you call a __stdcall function from a __cdecl, the __stdcall function cleans up the arguments on the stack, and then the __cdecl function does it again, possibly removing the calling functions return information.

The Microsoft convention for C tries to circumvent this by mangling the names. A __cdecl function is prefixed with an underscore. A __stdcall function prefixes with an underscore and suffixed with an at sign “@” and the number of bytes to be removed. Eg __cdecl f(x) is linked as _f, __stdcall f(int x) is linked as _f@4 where sizeof(int) is 4 bytes)

If you manage to get past the linker, enjoy the debugging mess.

Tip: if you gonna use the slack cleaner https://github.com/kfei/slack-cleaner

You will need to generate a token: https://api.slack.com/custom-integrations/legacy-tokens

1. Use git clone to clone your repository into a folder (say work). You should see a new subfolder, work/.git.
2. Open folder work in Visual Studio Code - everything should work fine!

PS: Blow away the temporary folder.

Those ones are shorter than the typeof operator version.

function foo(a, b) {
    a !== undefined || (a = 'defaultA');
    if(b === undefined) b = 'defaultB';
    ...
}

You have to check which Python you are using. I had the same problem because the Python I was using was not the same one that brew was using. In your command line:

1. which python
   output: /usr/bin/python
2. which brew
   output: /usr/local/bin/brew     //so they are different
3. cd /usr/local/lib/python2.7/site-packages
4. ls   //you can see PyQt4 and sip are here
5. Now you need to add usr/local/lib/python2.7/site-packages to your python path.
6. open ~/.bash_profile   //you will open your bash_profile file in your editor
7. Add 'export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH' to your bash file and save it
8. Close your terminal and restart it to reload the shell
9. python
10. import PyQt4    // it is ok now

It's a lot more simple that you think. You've signed into both your mobile and Chrome on your desktop using the same Google account. Google simply expect you will have your mobile with you most of the time. They take the location data from your phone and assume the location of your current desktop session is the same.

I proved this by RDPing into my Windows machine at home from work and checking Google maps remotely. It show my location as the same as Chrome on Linux at work.

If you don't have a mobile that is signed into Google then all they can do is lookup GeoIP data for the IP address assigned by your ISP. It will typically be wildly inaccurate.

I'm not an expert, but I guess in sed you'd first need to append the next line into the pattern space, bij using "N". From the section "Multiline Pattern Space" in "Advanced sed Commands" of the book sed & awk (Dale Dougherty and Arnold Robbins; O'Reilly 1997; page 107 in the preview):

The multiline Next (N) command creates a multiline pattern space by reading a new line of input and appending it to the contents of the pattern space. The original contents of pattern space and the new input line are separated by a newline. The embedded newline character can be matched in patterns by the escape sequence "\n". In a multiline pattern space, the metacharacter "^" matches the very first character of the pattern space, and not the character(s) following any embedded newline(s). Similarly, "$" matches only the final newline in the pattern space, and not any embedded newline(s). After the Next command is executed, control is then passed to subsequent commands in the script.

From man sed:

[2addr]N

Append the next line of input to the pattern space, using an embedded newline character to separate the appended material from the original contents. Note that the current line number changes.

I've used this to search (multiple) badly formatted log files, in which the search string may be found on an "orphaned" next line.

Here's how I would solve it:

1. Just Save your CSV File as a XLS Sheet in excel(By Doing so, you wouldn't have to worry about delimitiers. Excel's spreadsheet format will be read as a table and imported directly into a SQL Table)

2. Import the File Using SSIS

3. Write a Custom Script in the import manager to omit/modify the data you're looking for.(Or run a master script to scrutinize the data you're looking to remove)

Good Luck.

The tag in web.config is based on paths, whereas MVC works with controller actions and routes.

It is an architectural decision that might not make a lot of difference if you just want to prevent users that aren't logged in but makes a lot of difference when you try to apply authorization based in Roles and in cases that you want custom handling of types of Unauthorized.

The first case is covered from the answer of BobRock.

The user should have at least one of the following Roles to access the Controller or the Action

[Authorize(Roles = "Admin, Super User")]

The user should have both these roles in order to be able to access the Controller or Action

[Authorize(Roles = "Super User")]
[Authorize(Roles = "Admin")]

The users that can access the Controller or the Action are Betty and Johnny

[Authorize(Users = "Betty, Johnny")]

In ASP.NET Core you can use Claims and Policy principles for authorization through [Authorize].

options.AddPolicy("ElevatedRights", policy =>
                  policy.RequireRole("Administrator", "PowerUser", "BackupAdministrator"));

[Authorize(Policy = "ElevatedRights")]

The second comes very handy in bigger applications where Authorization might need to be implemented with different restrictions, process and handling according to the case. For this reason we can Extend the AuthorizeAttribute and implement different authorization alternatives for our project.

public class CustomAuthorizeAttribute: AuthorizeAttribute  
{  
    public override void OnAuthorization(AuthorizationContext filterContext)  
    {  }
}

The "correct-completed" way to do authorization in ASP.NET MVC is using the [Authorize] attribute.

UPDATE django version 2.1.7

I got this error sqlite3.OperationalError: database is locked using pytest with django.

Solution:

If we are using @pytest.mark.django_db decorator. What it does is create a in-memory-db for testing.

Named: file:memorydb_default?mode=memory&cache=shared We can get this name with:

from django.db import connection
db_path = connection.settings_dict['NAME']

To access this database and also edit it, do:

Connect to the data base:

with sqlite3.connect(db_path, uri=True) as conn:
    c = conn.cursor()

Use uri=True to specifies the disk file that is the SQLite database to be opened.

To avoid the error activate transactions in the decorator:

@pytest.mark.django_db(transaction=True)

Final function:

from django.db import connection

@pytest.mark.django_db(transaction=True)
def test_mytest():
    db_path = connection.settings_dict['NAME']
    with sqlite3.connect(db_path, uri=True) as conn:
        c = conn.cursor()
        c.execute('my amazing query')
        conn.commit()
    assert ... == ....

Here's a variation of Oscar's first version that doesn't use a for-each loop.

for (int i = 0; i < charArray.length; i++) {
    if (charArray[i] == 'q') {
        // do something
        break;
    }
}

You could have a boolean variable that gets set to false before the loop, then make "do something" set the variable to true, which you could test for after the loop. The loop could also be wrapped in a function call then just use 'return true' instead of the break, and add a 'return false' statement after the for loop.

Center a div inside td using margin, the trick is to make the div width same as image width.

<td>
    <div style="margin: 0 auto; width: 130px">
          <img src="me.jpg" alt="me" style="width: 130px" />
    </div>
</td>

For Python 3.6 and psutil 5.4.5 it is easier to use memory_percent() function listed here.

import os
import psutil
process = psutil.Process(os.getpid())
print(process.memory_percent())

tldr; Unload and reload the problem project.

When this happens to me I (used to) try closing VS and reopen it. That probably worked about half of the time. When it didn't work I would close the solution, delete the .suo file (or the entire .vs folder) and re-open the solution. So far this has always worked for me (more than 10 times in the last 6 months), but it is slightly tedious because some things get reset such as your build mode, startup project, etc.

Since it's usually just one project that's having the problem, I just tried unloading that project and reloading it, and this worked. My sample size is only 1 but it's much faster than the other two options so perhaps worth the attempt. (Update: some of my co-workers have now tried this too, and so far it's worked every time.) I suspect this works because it writes to the .suo file, and perhaps fixes the corrupted part of it that was causing the issue to begin with.

Note: this appears to work for VS 2019, 2017, and 2015.

Use the sign of the determinant of vectors (AB,AM), where M(X,Y) is the query point:

position = sign((Bx - Ax) * (Y - Ay) - (By - Ay) * (X - Ax))

It is 0 on the line, and +1 on one side, -1 on the other side.

Instead of writing this,

<script type="text/javascript">
function changeImage(a) {
    document.getElementById("img").src=a.src;
}
</script>

try:

<script type="text/javascript">
function changeImage(a) {
document.getElementById("img").src=a;
}
</script>
