Programs & Examples On #Mktime

Today, using PHP's DateTime objects is better:

<?php
$ddate = "2012-10-18";
$date = new DateTime($ddate);
$week = $date->format("W");
echo "Weeknummer: $week";

It's because in mktime(), it goes like this:

mktime(hour, minute, second, month, day, year);

Hence, your order is wrong.

<?php
$ddate = "2012-10-18";
$duedt = explode("-", $ddate);
$date  = mktime(0, 0, 0, $duedt[1], $duedt[2], $duedt[0]);
$week  = (int)date('W', $date);
echo "Weeknummer: " . $week;
?>

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed. Check more here.

Use the default date function.

$var = "20/04/2012";
echo date("Y-m-d", strtotime($var) );

EDIT I just tested it, and somehow, PHP doesn't work well with dd/mm/yyyy format. Here's another solution.

$var = '20/04/2012';
$date = str_replace('/', '-', $var);
echo date('Y-m-d', strtotime($date));

I used the data_connection_checker package to check the internet access even if the connection available by wifi or mobile, it works well: here is the code to check the connection:

bool result = await DataConnectionChecker().hasConnection;
if(result == true) {
   print('YAY! Free cute dog pics!');
} else {
   print('No internet :( Reason:');
   print(DataConnectionChecker().lastTryResults);
}

head over the package if you want more information. Data Connection Checker Package

To animate layout changes, you can add the following attribute to your LinearLayout

android:animateLayoutChanges="true"

and it will animate changes automatically for you.

For information, if android:animateLayoutChanges="true" is used, then custom animation via anim xml will not work.

I'm debugging an issue I'm having with SSL connecting to a database (MySQL RDS) using an ORM called, Prisma. The database connection string requires a PKCS12 (.p12) file (if interested, described here), which brought me here.

I know the question has been answered, but I found the following steps (in Github Issue#2676) to be helpful for creating a .p12 file and wanted to share. Good luck!

1. Generate 2048-bit RSA private key:

   openssl genrsa -out key.pem 2048

2. Generate a Certificate Signing Request:

   openssl req -new -sha256 -key key.pem -out csr.csr

3. Generate a self-signed x509 certificate suitable for use on web servers.

   openssl req -x509 -sha256 -days 365 -key key.pem -in csr.csr -out certificate.pem

4. Create SSL identity file in PKCS12 as mentioned here

   openssl pkcs12 -export -out client-identity.p12 -inkey key.pem -in certificate.pem

In case this error came from a web server: Try url encoding your post value. I was POSTing via "curl" and discovered I wasn't url-encoding my base64 value so characters like "+" were not escaped so the web server url-decode logic automatically ran url-decode and converted + to spaces.

"+" is a valid base64 character and perhaps the only character which gets mangled by an unexpected url-decode.

If your are on windows you can do it this way :

1. In your project root directory, Create file run.bat
2. Add your command with your choice of configurations in this file. For Example

ng serve --host 192.168.1.2 --open

3. Now you can click and open this file whenever you want to serve.

This not standard way but comfortable to use (which I feel).

this could do it:

perl -ne 'if(m/name="(.*?)"/){ print $1 . "\n"; }'

QMessageBox includes static methods to quickly ask such questions:

#include <QApplication>
#include <QMessageBox>

int main(int argc, char **argv)
{
    QApplication app{argc, argv};
    while (QMessageBox::question(nullptr,
                                 qApp->translate("my_app", "Test"),
                                 qApp->translate("my_app", "Are you sure you want to quit?"),
                                 QMessageBox::Yes|QMessageBox::No)
           != QMessageBox::Yes)
        // ask again
        ;
}

If your needs are more complex than provided for by the static methods, you should construct a new QMessageBox object, and call its exec() method to show it in its own event loop and obtain the pressed button identifier. For example, we might want to make "No" be the default answer:

#include <QApplication>
#include <QMessageBox>

int main(int argc, char **argv)
{
    QApplication app{argc, argv};
    auto question = new QMessageBox(QMessageBox::Question,
                                    qApp->translate("my_app", "Test"),
                                    qApp->translate("my_app", "Are you sure you want to quit?"),
                                    QMessageBox::Yes|QMessageBox::No,
                                    nullptr);
    question->setDefaultButton(QMessageBox::No);

    while (question->exec() != QMessageBox::Yes)
        // ask again
        ;
}

Here is my solution. I first create random numbers with random.uniform, format them in to string with double precision and then convert them back to float. You can adjust the precision by changing '.2f' to '.3f' etc..

import random
from decimal import Decimal

GndSpeedHigh = float(format(Decimal(random.uniform(5, 25)), '.2f'))
GndSpeedLow = float(format(Decimal(random.uniform(2, GndSpeedHigh)), '.2f'))
GndSpeedMean = float(Decimal(format(GndSpeedHigh + GndSpeedLow) / 2, '.2f')))
print(GndSpeedMean)

It is even easier in Swift:

let string : String = "Hello  "
let characters = Array(string)
println(characters)
// [H, e, l, l, o,  , , ,  , ]

This uses the facts that

• an Array can be created from a SequenceType, and
• String conforms to the SequenceType protocol, and its sequence generator enumerates the characters.

And since Swift strings have full support for Unicode, this works even with characters outside of the "Basic Multilingual Plane" (such as ) and with extended grapheme clusters (such as , which is actually composed of two Unicode scalars).

Update: As of Swift 2, String does no longer conform to SequenceType, but the characters property provides a sequence of the Unicode characters:

let string = "Hello  "
let characters = Array(string.characters)
print(characters)

This works in Swift 3 as well.

Update: As of Swift 4, String is (again) a collection of its Characters:

let string = "Hello  "
let characters = Array(string)
print(characters)
// ["H", "e", "l", "l", "o", " ", "", "", " ", ""]

If you don't need in a complete reference to the most part of algorithms and data structures that are in use and just want to get acquainted with common techniques I would recommend something more lightweight than Cormen, Sedgewick or Knuth. I think, Algorithms and Data Structures by N. Wirth is not as bad choice even in spite of it was printed far ago.

Bash program to wait for sftp to ask for a password then send it along:

#!/bin/bash
expect -c "
spawn sftp username@your_host
expect \"Password\"
send \"your_password_here\r\"
interact "

You may need to install expect, change the wording of 'Password' to lowercase 'p' to match what your prompt receives. The problems here is that it exposes your password in plain text in the file as well as in the command history. Which nearly defeats the purpose of having a password in the first place.

You could use CommitMonitor. This little tool uses very little RAM and notifies you of all the commits you've missed.

Programmatialy:

You can do programmatically using setTypeface() method:

Below is the code for default Typeface

textView.setTypeface(null, Typeface.NORMAL);      // for Normal Text
textView.setTypeface(null, Typeface.BOLD);        // for Bold only
textView.setTypeface(null, Typeface.ITALIC);      // for Italic
textView.setTypeface(null, Typeface.BOLD_ITALIC); // for Bold and Italic

and if you want to set custom Typeface:

textView.setTypeface(textView.getTypeface(), Typeface.NORMAL);      // for Normal Text
textView.setTypeface(textView.getTypeface(), Typeface.BOLD);        // for Bold only
textView.setTypeface(textView.getTypeface(), Typeface.ITALIC);      // for Italic
textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC); // for Bold and Italic

XML:

You can set Directly in XML file in like:

android:textStyle="normal"
android:textStyle="normal|bold"
android:textStyle="normal|italic"
android:textStyle="bold"
android:textStyle="bold|italic"

I found how to automate the build and archive process from the comand line, I just wrote a blog article explaining how you can achieve that.

The command you have to use is xcrun:

/usr/bin/xcrun -sdk iphoneos PackageApplication \
-v "${RELEASE_BUILDDIR}/${APPLICATION_NAME}.app" \
-o "${BUILD_HISTORY_DIR}/${APPLICATION_NAME}.ipa" \
--sign "${DEVELOPER_NAME}" \
--embed "${PROVISONING_PROFILE}"

You will find all the details in the article. If you have any questions dont hesitate to ask.

Both approaches will catch all exceptions. There is no significant difference between your two code examples except that the first will generate a compiler warning because ex is declared but not used.

But note that some exceptions are special and will be rethrown automatically.

ThreadAbortException is a special exception that can be caught, but it will automatically be raised again at the end of the catch block.

http://msdn.microsoft.com/en-us/library/system.threading.threadabortexception.aspx

As mentioned in the comments, it is usually a very bad idea to catch and ignore all exceptions. Usually you want to do one of the following instead:

• Catch and ignore a specific exception that you know is not fatal.

  catch (SomeSpecificException)
  {
      // Ignore this exception.
  }
  

• Catch and log all exceptions.

  catch (Exception e)
  {
      // Something unexpected went wrong.
      Log(e);
      // Maybe it is also necessary to terminate / restart the application.
  }
  

• Catch all exceptions, do some cleanup, then rethrow the exception.

  catch
  {
      SomeCleanUp();
      throw;
  }
  

Note that in the last case the exception is rethrown using throw; and not throw ex;.

As per this answer over here: str='foo%20%5B12%5D' encodes foo [12]:

%20 is space
%5B is '['
and %5D is ']'

This is called percent encoding and is used in encoding special characters in the url parameter values.

EDIT By the way as I was reading https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/encodeURI#Description, it just occurred to me why so many people make the same search. See the note on the bottom of the page:

Also note that if one wishes to follow the more recent RFC3986 for URL's, making square brackets reserved (for IPv6) and thus not encoded when forming something which could be part of a URL (such as a host), the following may help.

function fixedEncodeURI (str) {
    return encodeURI(str).replace(/%5B/g, '[').replace(/%5D/g, ']');
}

Hopefully this will help people sort out their problems when they stumble upon this question.

$ThatTime ="14:08:10";
if (time() >= strtotime($ThatTime)) {
  echo "ok";
}

A solution using DateTime (that also regards the timezone).

$dateTime = new DateTime($ThatTime);
if ($dateTime->diff(new DateTime)->format('%R') == '+') {
  echo "OK";
}

INSERT INTO table1 (col1, col2, col3)
SELECT column1, column2, column3
FROM table2                                        

with prototype and without space :

 String.prototype.trimToLength = function (trimLenght) {
    return this.length > trimLenght ? this.substring(0, trimLenght - 3) + '...' : this
};

I have resolved this problem to add some change like git add -A and git commit again.

You can also use the Activity Monitor to identify and quit the process using the port.

Edit: Because this answer is very popular, I have updated it to reflect up-to-date practices.

Node >=10

The new { recursive: true } option of Node's fs now allows this natively. This option mimics the behaviour of UNIX's mkdir -p. It will recursively make sure every part of the path exist, and will not throw an error if any of them do.

(Note: it might still throw errors such as EPERM or EACCESS, so better still wrap it in a try {} catch (e) {} if your implementation is susceptible to it.)

Synchronous version.

fs.mkdirSync(dirpath, { recursive: true })

Async version

await fs.promises.mkdir(dirpath, { recursive: true })

Older Node versions

Using a try {} catch (err) {}, you can achieve this very gracefully without encountering a race condition.

In order to prevent dead time between checking for existence and creating the directory, we simply try to create it straight up, and disregard the error if it is EEXIST (directory already exists).

If the error is not EEXIST, however, we ought to throw an error, because we could be dealing with something like an EPERM or EACCES

function ensureDirSync (dirpath) {
  try {
    return fs.mkdirSync(dirpath)
  } catch (err) {
    if (err.code !== 'EEXIST') throw err
  }
}

For mkdir -p-like recursive behaviour, e.g. ./a/b/c, you'd have to call it on every part of the dirpath, e.g. ./a, ./a/b, .a/b/c

I use addActionListener for JButtons while addItemListener is more convenient for a JToggleButton. Together with if(event.getStateChange()==ItemEvent.SELECTED), in the latter case, I add Events for whenever the JToggleButton is checked/unchecked.

I'm assuming that you're wanting to insert a style tag versus a link tag (referencing an external CSS), so that's what the following example does:

<html>
 <head>
  <title>Example Page</title>
 </head>
 <body>
  <span>
   This is styled dynamically via JavaScript.
  </span>
 </body>
 <script type="text/javascript">
   var styleNode = document.createElement('style');
   styleNode.type = "text/css";
   // browser detection (based on prototype.js)
   if(!!(window.attachEvent && !window.opera)) {
        styleNode.styleSheet.cssText = 'span { color: rgb(255, 0, 0); }';
   } else {
        var styleText = document.createTextNode('span { color: rgb(255, 0, 0); } ');
        styleNode.appendChild(styleText);
   }
   document.getElementsByTagName('head')[0].appendChild(styleNode);
 </script>
</html>

Also, I noticed in your question that you are using innerHTML. This is actually a non-standard way of inserting data into a page. The best practice is to create a text node and append it to another element node.

With respect to your final question, you're going to hear some people say that your work should work across all of the browsers. It all depends on your audience. If no one in your audience is using Chrome, then don't sweat it; however, if you're looking to reach the biggest audience possible, then it's best to support all major A-grade browsers

You can append a queryString to your src and change it only when you will release an updated version:

<script src="test.js?v=1"></script>

In this way the browser will use the cached version until a new version will be specified (v=2, v=3...)

You might want to do it like this:

DateTime? lastPostDate =  (DateTime?)(reader.IsDbNull(3) ? null : reader[3]); 

The problem you are having is that the ternary operator wants a viable cast between the left and right sides. And null can't be cast to DateTime.

Note the above works because both sides of the ternary are object's. The object is explicitly cast to DateTime? which works: as long as reader[3] is in fact a date.

Try

string reversed(temp.rbegin(), temp.rend());

EDIT: Elaborating as requested.

string::rbegin() and string::rend(), which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator* to dereference to an element, i.e. a character of the string, and operator++ to advance to the "next" element), such that rbegin() points to the last character of the string, rend() points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).

Finally, the constructor we are passing these iterators into is a string constructor of the form:

template <typename Iterator>
string(Iterator first, Iterator last);

which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.

I’d like to expand a bit on Saxon Druce’s excellent answer.

As stated, you can redirect the output of an executable in the current directory like so:

powershell ".\something.exe | tee test.txt"

However, this only logs stdout to test.txt. It doesn’t also log stderr.

The obvious solution would be to use something like this:

powershell ".\something.exe 2>&1 | tee test.txt"

However, this won’t work for all something.exes. Some something.exes will interpret the 2>&1 as an argument and fail. The correct solution is to instead only have apostrophes around the something.exe and its switches and arguments, like so:

powershell ".\something.exe --switch1 --switch2 … arg1 arg2 …" 2>&1 | tee test.txt

Try:

$a1=@(1,2,3,4,5)
$b1=@(1,2,3,4,5,6)
(Compare-Object $a1 $b1).InputObject

Or, you can use:

(Compare-Object $b1 $a1).InputObject

The order doesn't matter.

You can try this.

import csv
import pandas as pd
df = pd.read_csv(filepath,encoding='unicode_escape')

To complete @SamSaffron's answer :

You can use class_name with either foreign_key or inverse_of. I personally prefer the more abstract declarative, but it's really just a matter of taste :

class BlogPost
  has_many :images, class_name: "BlogPostImage", inverse_of: :blog_post  
end

and you need to make sure you have the belongs_to attribute on the child model:

class BlogPostImage
  belongs_to :blog_post
end

I found this can also occur if the most of the data plotted is outside of the axis limits. In that case, adjust the axis scales accordingly.

This post got me to my answer even though the answer is missing from this post. I felt I should give back.

The challenge here is in the inconsistent behavior of BeautifulSoup.find when searching with and without text.

Note: If you have BeautifulSoup, you can test this locally via:

curl https://gist.githubusercontent.com/RichardBronosky/4060082/raw/test.py | python

Code: https://gist.github.com/4060082

# Taken from https://gist.github.com/4060082
from BeautifulSoup import BeautifulSoup
from urllib2 import urlopen
from pprint import pprint
import re

soup = BeautifulSoup(urlopen('https://gist.githubusercontent.com/RichardBronosky/4060082/raw/test.html').read())
# I'm going to assume that Peter knew that re.compile is meant to cache a computation result for a performance benefit. However, I'm going to do that explicitly here to be very clear.
pattern = re.compile('Fixed text')

# Peter's suggestion here returns a list of what appear to be strings
columns = soup.findAll('td', text=pattern, attrs={'class' : 'pos'})
# ...but it is actually a BeautifulSoup.NavigableString
print type(columns[0])
#>> <class 'BeautifulSoup.NavigableString'>

# you can reach the tag using one of the convenience attributes seen here
pprint(columns[0].__dict__)
#>> {'next': <br />,
#>>  'nextSibling': <br />,
#>>  'parent': <td class="pos">\n
#>>       "Fixed text:"\n
#>>       <br />\n
#>>       <strong>text I am looking for</strong>\n
#>>   </td>,
#>>  'previous': <td class="pos">\n
#>>       "Fixed text:"\n
#>>       <br />\n
#>>       <strong>text I am looking for</strong>\n
#>>   </td>,
#>>  'previousSibling': None}

# I feel that 'parent' is safer to use than 'previous' based on http://www.crummy.com/software/BeautifulSoup/bs4/doc/#method-names
# So, if you want to find the 'text' in the 'strong' element...
pprint([t.parent.find('strong').text for t in soup.findAll('td', text=pattern, attrs={'class' : 'pos'})])
#>> [u'text I am looking for']

# Here is what we have learned:
print soup.find('strong')
#>> <strong>some value</strong>
print soup.find('strong', text='some value')
#>> u'some value'
print soup.find('strong', text='some value').parent
#>> <strong>some value</strong>
print soup.find('strong', text='some value') == soup.find('strong')
#>> False
print soup.find('strong', text='some value') == soup.find('strong').text
#>> True
print soup.find('strong', text='some value').parent == soup.find('strong')
#>> True

Though it is most certainly too late to help the OP, I hope they will make this as the answer since it does satisfy all quandaries around finding by text.

The difference is not just for Chrome but for most of the web browsers.

F5 refreshes the web page and often reloads the same page from the cached contents of the web browser. However, reloading from cache every time is not guaranteed and it also depends upon the cache expiry.

Shift + F5 forces the web browser to ignore its cached contents and retrieve a fresh copy of the web page into the browser.

Shift + F5 guarantees loading of latest contents of the web page.
However, depending upon the size of page, it is usually slower than F5.

You may want to refer to: What requests do browsers' "F5" and "Ctrl + F5" refreshes generate?

You can also work with "overflow: hidden" or "overflow-x: hidden" (for just the width). This requires a defined width (and/or height?) and maybe a "display: block" as well.

"Overflow:Hidden" hides the whole content, which does not fit into the defined box.

Example:

http://jsfiddle.net/NAJvp/

HTML:

<table border="1">
    <tr>
        <td><div>aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</div></td>
        <td>bbb</td>
        <td>cccc</td>
    </tr>
</table>

CSS:

td div { width: 100px; overflow-y: hidden; }

EDIT: Shame on me, I've seen, you already use "overflow". I guess it doesn't work, because you don't set "display: block" to your element ...

I recently run into the same problem. I solved it by implementing my own ImageView class.

Here is my Kotlin implementation:

class MyImageView(context: Context): ImageView(context) {
    private var currentDrawableId: Int? = null

    override fun setImageResource(resId: Int) {
        super.setImageResource(resId)
        currentDrawableId = resId
    }

    fun getDrawableId() {
        return currentDrawableId
    }

    fun compareCurrentDrawable(toDrawableId: Int?): Boolean {
        if (toDrawableId == null || currentDrawableId != toDrawableId) {
            return false
        }

        return true
    }

}

I just use echo no arguments

echo "Hello"
echo
echo "World"

Assuming we imported pandas as pd and df is our dataframe

pd.to_datetime(df['date'], unit='s')

works for me.

Too bad that Sharon's solution cannot be used anymore. I've added Josh O'Brien's solution with asieira's modification to my .Rprofile file:

read.text = function(pathname)
{
    return (paste(readLines(pathname), collapse="\n"))
}

and use it like this: txt = read.text('path/to/my/file.txt'). I couldn't replicate bumpkin's (28 oct. 14) finding, and writeLines(txt) showed the contents of file.txt. Also, after write(txt, '/tmp/out') the command diff /tmp/out path/to/my/file.txt reported no differences.

There is no such option. What you can do is to run mkdir -p before copying the file

I made a very cool script you can use to copy files in locations that doesn't exist

#!/bin/bash
if [ ! -d "$2" ]; then
    mkdir -p "$2"
fi
cp -R "$1" "$2"

Now just save it, give it permissions and run it using

./cp-improved SOURCE DEST

I put -R option but it's just a draft, I know it can be and you will improve it in many ways. Hope it helps you

The compiler cannot guess what should be passed for the base constructor argument. You have to do it explicitly:

public class child : parent {
    public child(int i) : base(i) {
        Console.WriteLine("child");
    }
}

You can make it like that:

    <html>
<head>
    <style>
        .round {
            display:block;
            width: 55px;
            height: 55px;
            border-radius: 50%;
            overflow: hidden;
            padding:5px 4px;
        }
        .round img {
            width: 45px;
        }
    </style>
</head>
<body>
    <div class="round">
        <img src="image.jpg" />
    </div>
</body>

A big part of the REST philosophy is to exploit as many standard features of the HTTP protocol as possible when designing your API. Applying that philosophy to authentication, client and server would utilize standard HTTP authentication features in the API.

Login screens are great for human user use cases: visit a login screen, provide user/password, set a cookie, client provides that cookie in all future requests. Humans using web browsers can't be expected to provide a user id and password with each individual HTTP request.

But for a REST API, a login screen and session cookies are not strictly necessary, since each request can include credentials without impacting a human user; and if the client does not cooperate at any time, a 401 "unauthorized" response can be given. RFC 2617 describes authentication support in HTTP.

TLS (HTTPS) would also be an option, and would allow authentication of the client to the server (and vice versa) in every request by verifying the public key of the other party. Additionally this secures the channel for a bonus. Of course, a keypair exchange prior to communication is necessary to do this. (Note, this is specifically about identifying/authenticating the user with TLS. Securing the channel by using TLS / Diffie-Hellman is always a good idea, even if you don't identify the user by its public key.)

An example: suppose that an OAuth token is your complete login credentials. Once the client has the OAuth token, it could be provided as the user id in standard HTTP authentication with each request. The server could verify the token on first use and cache the result of the check with a time-to-live that gets renewed with each request. Any request requiring authentication returns 401 if not provided.

String strLong = Long.toString(longNumber);

Simple and works fine :-)

Even if modern browsers support WebSockets now, I think there is no need to throw SocketIO away and it still has its place in any nowadays project. It's easy to understand, and personally, I learned how WebSockets work thanks to SocketIO.

As said in this topic, there's a plenty of integration libraries for Angular, React, etc. and definition types for TypeScript and other programming languages.

The other point I would add to the differences between Socket.io and WebSockets is that clustering with Socket.io is not a big deal. Socket.io offers Adapters that can be used to link it with Redis to enhance scalability. You have ioredis and socket.io-redis for example.

Yes I know, SocketCluster exists, but that's off-topic.

The accepted answer is correct, but I prefer:

@{int count = 0;} 
@foreach (var item in Model.Resources) 
{ 
    @Html.Raw(count <= 3 ? "<div class=\"resource-row\">" : "")  
    // some code 
    @Html.Raw(count <= 3 ? "</div>" : "")  
    @(count++)
} 

I hope this inspires someone, even though I'm late to the party.

I was facing this issue "ModuleNotFoundError: No module named 'encodings" after updating to macOS Catalina.

I was having multiple versions of Python installed in my system.

Removing all the python versions(2.7 and 3.7.4) from macOS system and reinstalling the latest python 3.8 worked for me.

To remove a python from macOS, I've followed the instructions from here How to uninstall Python 2.7 on a Mac OS X 10.6.4?

The above link is for python 2.7 and but you can use the same for 3.7 also.

How about this?

def replace_all(dict, str):
    for key in dict:
        str = str.replace(key, dict[key])
    return str

then

print(replace_all({"&":"\&", "#":"\#"}, "&#"))

output

By default, Apache prohibits using an .htaccess file to apply rewrite rules, so

Step 1 — Enabling mod_rewrite (if not Enabled) First, we need to activate mod_rewrite. It's available but not enabled with a clean Apache 2 installation.

$ sudo a2enmod rewrite

This will activate the module or alert you that the module is already enabled. To put these changes into effect, restart Apache.

$ sudo systemctl restart apache2

mod_rewrite is now fully enabled. In the next step we will set up an .htaccess file that we'll use to define rewrite rules for redirects.

Step 2 — Setting Up .htaccess Open the default Apache configuration file using nano or your favorite text editor.

$ sudo nano /etc/apache2/sites-available/000-default.conf

Inside that file, you will find a block starting on the first line. Inside of that block, add the following new block so your configuration file looks like the following. Make sure that all blocks are properly indented.

/etc/apache2/sites-available/000-default.conf

<VirtualHost *:80>
    <Directory /var/www/html>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
    </Directory>

    . . . 
</VirtualHost>

Save and close the file. To put these changes into effect, restart Apache.

$ sudo systemctl restart apache2

Done. Your .htacess should work. This link may actually help somebody https://www.digitalocean.com/community/tutorials/how-to-rewrite-urls-with-mod_rewrite-for-apache-on-ubuntu-16-04

If you are looking for ad-hoc items rather than something that you would put into SSIS. From within SSMS simply highlight the results grid, copy, then paste into excel, it isn't elegant, but works. Then you can save as native .xls rather than .csv

Scripting is inevitable.

This isn't provided because of the security risk. <input type='file' /> is closest, but not what you are looking for.

Checkout this example that uses Javascript to achieve what you want.

If the OS is windows, you can use VB scripts to access the core control files to browse for a folder.

Cmd + Shift + 7 will comment the selected lines.

On Mac OS X Mavericks (10.9.3), I solved this by doing the follows:

Install libjpeg by brew (package management system)

brew install libjpeg

reinstall pillow (I use pillow instead of PIL)

pip install -I pillow

It works because the stack has not been altered (yet) since a was put there. Call a few other functions (which are also calling other functions) before accessing a again and you will probably not be so lucky anymore... ;-)

Sometimes, a row contain double quote column. When csv reader try read this row, not understood end of column and fire this raise. Solution is below:

reader = csv.reader(cf, quoting=csv.QUOTE_MINIMAL)

Assume your code is looking for the file say app.properties. Copy this file to any dir and add this dir to classpath, by creating a setenv.sh in the bin dir of tomcat.

In your setenv.sh of tomcat( if this file is not existing, create one , tomcat will load this setenv.sh file. #!/bin/sh CLASSPATH="$CLASSPATH:/home/user/config_my_prod/"

You should not have your properties files in ./webapps//WEB-INF/classes/app.properties

Tomcat class loader will override the with the one from WEB-INF/classes/

A good read: https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

Assuming the iFrame has a name attribute of "myIframe":

<a href="http://www.google.com" target="myIframe">Link Text</a> 

You can also accomplish this with the use of Javascript. The iFrame has a src attribute which specifies the location it shows. As such, it's a simple matter of binding the click of a link to changing that src attribute.

In docker image of PHP-FPM, i've see such approach:

# cat /usr/local/etc/php-fpm.d/docker.conf
[global]
error_log = /proc/self/fd/2

[www]
; if we send this to /proc/self/fd/1, it never appears
access.log = /proc/self/fd/2

There are many methods to this, here are some of them:

1. Using the predefined str method islower():

   >>> c = 'a'
   >>> c.islower()
   True
   

2. Using the ord() function to check whether the ASCII code of the letter is in the range of the ASCII codes of the lowercase characters:

   >>> c = 'a'
   >>> ord(c) in range(97, 123)
   True
   

3. Checking if the letter is equal to it's lowercase form:

   >>> c = 'a'
   >>> c.lower() == c
   True
   

4. Checking if the letter is in the list ascii_lowercase of the string module:

   >>> from string import ascii_lowercase
   >>> c = 'a'
   >>> c in ascii_lowercase
   True
   

But that may not be all, you can find your own ways if you don't like these ones: D.

Finally, let's start detecting:

d = str(input('enter a string : '))
lowers = [c for c in d if c.islower()]

# here i used islower() because it's the shortest and most-reliable
# one (being a predefined function), using this list comprehension
# is (probably) the most efficient way of doing this

1. Assuming margin: 0 auto then the element should be centered, but the width is left as-is--whatever it is calculated to be, disregarding any margin settings.
2. If you set the <INPUT> tag to display:block, then it should be centered with margin: 0 auto.

See Visual formatting model details - calculating widths and margins from the CSS 2.1 specs for more details. Relavent bits include:

In a block formatting context, each box's left outer edge touches the left edge of the containing block.

and

When the total width of the inline boxes on a line is less than the width of the line box containing them, their horizontal distribution within the line box is determined by the 'text-align' property.

finally

If 'width' is set to 'auto', any other 'auto' values become '0' and 'width' follows from the resulting equality.

If both 'margin-left' and 'margin-right' are 'auto', their used values are equal. This horizontally centers the element with respect to the edges of the containing block.

I just wrote this short script; seems to work.

/**
 * Find all the elements with a tagName that matches.
 * @param {RegExp} regEx  regular expression to match against tagName
 * @returns {Array}       elements in the DOM that match
 */
function getAllTagMatches(regEx) {
  return Array.prototype.slice.call(document.querySelectorAll('*')).filter(function (el) { 
    return el.tagName.match(regEx);
  });
}
getAllTagMatches(/^di/i); // Returns an array of all elements that begin with "di", eg "div"

You simply combine the ideas of a link to another page, as with href=foo.html, and a link to an element on the same page, as with href=#bar, so that the fragment like #bar is written immediately after the URL that refers to another page:

<a href="foo.html#bar">Some nice link text</a>

The target is specified the same was as when linking inside one page, e.g.

<div id="bar">
<h2>Some heading</h2>
Some content
</div>

or (if you really want to link specifically to a heading only)

<h2 id="bar">Some heading</h2>

I've found out the solution! Thanks to Firebug ;)

//"markers" is an array that I declared which contains all the marker of the map
//"i" is the index of the marker in the array that I want to trigger the OnClick event

//V2 version is:
GEvent.trigger(markers[i], 'click');

//V3 version is:
google.maps.event.trigger(markers[i], 'click');

Here is my jQuery plugin:

(function($) {
    'use strict';
    $.fn.tooltipOnOverflow = function() {
        $(this).on("mouseenter", function() {
            if (this.offsetWidth < this.scrollWidth) {
                $(this).attr('title', $(this).text());
            } else {
                $(this).removeAttr("title");
            }
        });
    };
})(jQuery);

Usage:

$("td, th").tooltipOnOverflow();

Edit:

I have made a gist for this plugin. https://gist.github.com/UziTech/d45102cdffb1039d4415

The id should set as auto-increment.

To modify an existing id column to auto-increment, just add this

ALTER TABLE card_games MODIFY id int NOT NULL AUTO_INCREMENT;

Quite apart from the timing, this code you show is simply incorrect: you execute 100 connections (completely ignoring all but the last one), and then when you do the first execute call you pass it a local variable query_stmt which you only initialize after the execute call.

First, make your code correct, without worrying about timing yet: i.e. a function that makes or receives a connection and performs 100 or 500 or whatever number of updates on that connection, then closes the connection. Once you have your code working correctly is the correct point at which to think about using timeit on it!

Specifically, if the function you want to time is a parameter-less one called foobar you can use timeit.timeit (2.6 or later -- it's more complicated in 2.5 and before):

timeit.timeit('foobar()', number=1000)

You'd better specify the number of runs because the default, a million, may be high for your use case (leading to spending a lot of time in this code;-).

A . in regex is a metacharacter, it is used to match any character. To match a literal dot, you need to escape it, so \.

time.clock() was removed in Python 3.8 because it had platform-dependent behavior:

• On Unix, return the current processor time as a floating point number expressed in seconds.

• On Windows, this function returns wall-clock seconds elapsed since the first call to this function, as a floating point number

  print(time.clock()); time.sleep(10); print(time.clock())
  # Linux  :  0.0382  0.0384   # see Processor Time
  # Windows: 26.1224 36.1566   # see Wall-Clock Time
  

So which function to pick instead?

• Processor Time: This is how long this specific process spends actively being executed on the CPU. Sleep, waiting for a web request, or time when only other processes are executed will not contribute to this.

  • Use time.process_time()

• Wall-Clock Time: This refers to how much time has passed "on a clock hanging on the wall", i.e. outside real time.

  • Use time.perf_counter()

    • time.time() also measures wall-clock time but can be reset, so you could go back in time
    • time.monotonic() cannot be reset (monotonic = only goes forward) but has lower precision than time.perf_counter()

Old post I know, but using Select(x => x) can be useful to split the EF Core (or even just Linq) expression up into a query builder.

This is handy for adding dynamic conditions.

For example:

public async Task<User> GetUser(Guid userId, string userGroup, bool noTracking = false)
{
    IQueryable<User> queryable = _context.Users.Select(x => x);

    if(!string.IsNullOrEmpty(userGroup))
        queryable = queryable.Where(x => x.UserGroup == userGroup);

    if(noTracking)
        queryable = queryable.AsNoTracking();

    return await queryable.FirstOrDefaultAsync(x => x.userId == userId);
}

They are both going to have the same effect.

However, as pointed out in the comments: $(window).scrollTop() is supported by more web browsers than $('html').scrollTop().

.htaccess:

php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on
php_flag  log_errors on

This is for all who want to unpack and modify the original system.img that you can flash using recovery. system.img (which you get from the google factory images for example) represents a sparse ext4 loop mounted file system. It is mounted into /system of your device. Note that this tutorial is for ext4 file system. You may have system image which is yaffs2, for example.

The way it is mounted on Galaxy Nexus:

/dev/block/platform/omap/omap_hsmmc.0/by-name/system /system ext4 ro,relatime,barrier=1,data=ordered 0 0

Prerequisites:

• Linux box or virtual machine
• simg2img and make_ext4fs binaries, which can be downloaded from the linux package android-tools-fsutils

Procedure:

Place your system.img and the 2 binaries in one directory, and make sure the binaries have exec permission.

Part 1 – mount the file-system

mkdir sys
./simg2img system.img sys.raw
sudo mount -t ext4 -o loop sys.raw sys/

Then you have your system partition mounted in ‘sys/’ and you can modify whatever you want in ‘sys/’. For example de-odex apks and framework jars.

Part 2 – create a new flashable system image

sudo ./make_ext4fs -s -l 512M -a system new.img sys/
sudo umount sys
rm -fr sys

Now you can simply type:

fastboot flash system new.img

This is what I have tried out:

1. You need to make sure you give your buttons different names
2. Write an if statement that will do the required action if either button is clicked.

<form>
    <input type="text" name="field1" /> <!-- Put your cursor in this field and press Enter -->

    <input type="submit" name="prev" value="Previous Page" /> <!-- This is the button that will submit -->
    <input type="submit" name="next" value="Next Page" /> <!-- But this is the button that I WANT to submit -->
</form>

In PHP,

if(isset($_POST['prev']))
{
    header("Location: previous.html");
    die();
}

if(isset($_POST['next']))
{
    header("Location: next.html");
    die();
}

Easy. Use a bitwise AND to compare your number with the value 2^bitNumber, which can be cheaply calculated by bit-shifting.

//your black magic
var bit = (b & (1 << bitNumber-1)) != 0;

EDIT: To add a little more detail because there are a lot of similar answers with no explanation:

A bitwise AND compares each number, bit-by-bit, using an AND join to produce a number that is the combination of bits where both the first bit and second bit in that place were set. Here's the logic matrix of AND logic in a "nibble" that shows the operation of a bitwise AND:

  0101
& 0011
  ----
  0001 //Only the last bit is set, because only the last bit of both summands were set

In your case, we compare the number you passed with a number that has only the bit you want to look for set. Let's say you're looking for the fourth bit:

  11010010
& 00001000
  --------
  00000000 //== 0, so the bit is not set

  11011010
& 00001000
  --------
  00001000 //!= 0, so the bit is set

Bit-shifting, to produce the number we want to compare against, is exactly what it sounds like: take the number, represented as a set of bits, and shift those bits left or right by a certain number of places. Because these are binary numbers and so each bit is one greater power-of-two than the one to its right, bit-shifting to the left is equivalent to doubling the number once for each place that is shifted, equivalent to multiplying the number by 2^x. In your example, looking for the fourth bit, we perform:

       1 (2^0) << (4-1) ==        8 (2^3)
00000001       << (4-1) == 00001000

Now you know how it's done, what's going on at the low level, and why it works.

This worked for me. Each month on X axis

str_month_list = ['January','February','March','April','May','June','July','August','September','October','November','December']
ax.set_xticks(range(0,12))
ax.set_xticklabels(str_month_list)

This is the easiest way I found:

        BtnUpload.Style.Add("display", "none");
        FileUploader.Style.Add("display", "none");
        BtnAccept.Style.Add("display", "inherit");
        BtnClear.Style.Add("display", "inherit");

I have the opposite in the Else, so it handles displaying them as well. This can go in the Page's Load or in a method to refresh the controls on the page.

YES, you can Update and Insert into view and that edit will be reflected on the original table....
BUT
1-the view should have all the NOT NULL values on the table
2-the update should have the same rules as table... "updating primary key related to other foreign key.. etc"...

Building on Matías Fidemraizer's answer, here is a version that supports binding to object properties other than strings.

using System.Collections.Generic;
using System.Linq;
using System.Reflection;

namespace WebOpsApi.Shared.Helpers
{
    public static class MappingExtension
    {
        public static T ToObject<T>(this IDictionary<string, object> source)
            where T : class, new()
        {
            var someObject = new T();
            var someObjectType = someObject.GetType();

            foreach (var item in source)
            {
                var key = char.ToUpper(item.Key[0]) + item.Key.Substring(1);
                var targetProperty = someObjectType.GetProperty(key);


                if (targetProperty.PropertyType == typeof (string))
                {
                    targetProperty.SetValue(someObject, item.Value);
                }
                else
                {

                    var parseMethod = targetProperty.PropertyType.GetMethod("TryParse",
                        BindingFlags.Public | BindingFlags.Static, null,
                        new[] {typeof (string), targetProperty.PropertyType.MakeByRefType()}, null);

                    if (parseMethod != null)
                    {
                        var parameters = new[] { item.Value, null };
                        var success = (bool)parseMethod.Invoke(null, parameters);
                        if (success)
                        {
                            targetProperty.SetValue(someObject, parameters[1]);
                        }

                    }
                }
            }

            return someObject;
        }

        public static IDictionary<string, object> AsDictionary(this object source, BindingFlags bindingAttr = BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.Instance)
        {
            return source.GetType().GetProperties(bindingAttr).ToDictionary
            (
                propInfo => propInfo.Name,
                propInfo => propInfo.GetValue(source, null)
            );
        }
    }
}

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

Code for your reference:

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

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

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

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

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

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

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

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

int main(void) {

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

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

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

    return 0;
}

I have put together a collection of categories for NSData and NSString which uses solutions found on Jeff LaMarche's blog and some hints by Quinn Taylor here on Stack Overflow.

It uses categories to extend NSData to provide AES256 encryption and also offers an extension of NSString to BASE64-encode encrypted data safely to strings.

Here's an example to show the usage for encrypting strings:

NSString *plainString = @"This string will be encrypted";
NSString *key = @"YourEncryptionKey"; // should be provided by a user

NSLog( @"Original String: %@", plainString );

NSString *encryptedString = [plainString AES256EncryptWithKey:key];
NSLog( @"Encrypted String: %@", encryptedString );

NSLog( @"Decrypted String: %@", [encryptedString AES256DecryptWithKey:key] );

Thanks for all the helpful hints!

To measure the actual number of used threads, you can check Thread.activeCount():

    Runnable r = () -> IntStream
            .range(-42, +42)
            .parallel()
            .map(i -> Thread.activeCount())
            .max()
            .ifPresent(System.out::println);

    ForkJoinPool.commonPool().submit(r).join();
    new ForkJoinPool(42).submit(r).join();

This can produce on a 4-core CPU an output like:

5 // common pool
23 // custom pool

Without .parallel() it gives:

3 // common pool
4 // custom pool

The device I tested at had wrong time set. So when I tried accessing a page with a certificate that would run out soon it would deny access because the device though the certificate had expired. To fix, set proper time on the device!

The PowerShell execution policy is default set to Restricted. You can change the PowerShell execution policies with Set-ExecutionPolicy cmdlet. To run outside script set policy to RemoteSigned.

PS C:> Set-ExecutionPolicy RemoteSigned Below is the list of four different execution policies in PowerShell

Restricted – No scripts can be run. AllSigned – Only scripts signed by a trusted publisher can be run. RemoteSigned – Downloaded scripts must be signed by a trusted publisher. Unrestricted – All Windows PowerShell scripts can be run.

If you need a small and specific mechanism, you can search for DLL Triggers info.

You should check if the callback exists, and is an executable function:

if (callback && typeof(callback) === "function") {
    // execute the callback, passing parameters as necessary
    callback();
}

A lot of libraries (jQuery, dojo, etc.) use a similar pattern for their asynchronous functions, as well as node.js for all async functions (nodejs usually passes error and data to the callback). Looking into their source code would help!

        return super.instantiateItem(container, virtualPosition);
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        int virtualPosition = position % mActualTitleListSize;
        super.destroyItem(container, virtualPosition, object);
    }

This approach will work with any psql command from the simplest to the most complex without requiring any changes or adjustments to the original command.

Done! Thanks! =D

Now using Excel 2013 and this happens EVERY time I extend my display while Excel is running (and every time I remove the extension).

The fix I've started implementing is using hyperlinks instead of buttons and one to open a userform with all the other activeX controls on.

Considering that the accepted answer is probably inefficient for large arrays, O(nm), I usually prefer this approach, O(2n + 2m):

function mergeArrays(arr1 = [], arr2 = []){
    //Creates an object map of id to object in arr1
    const arr1Map = arr1.reduce((acc, o) => {
        acc[o.id] = o;
        return acc;
    }, {});
    //Updates the object with corresponding id in arr1Map from arr2, 
    //creates a new object if none exists (upsert)
    arr2.forEach(o => {
        arr1Map[o.id] = o;
    });

    //Return the merged values in arr1Map as an array
    return Object.values(arr1Map);
}

Unit test:

it('Merges two arrays using id as the key', () => {
   var arr1 = [{id:'124',name:'qqq'}, {id:'589',name:'www'}, {id:'45',name:'eee'}, {id:'567',name:'rrr'}];
   var arr2 = [{id:'124',name:'ttt'}, {id:'45',name:'yyy'}];
   const actual = mergeArrays(arr1, arr2);
   const expected = [{id:'124',name:'ttt'}, {id:'589',name:'www'}, {id:'45',name:'yyy'}, {id:'567',name:'rrr'}];
   expect(actual.sort((a, b) => (a.id < b.id)? -1: 1)).toEqual(expected.sort((a, b) => (a.id < b.id)? -1: 1));
})

There is a (somewhat) related question on StackOverflow:

• Showing an image with pylab.imshow()

Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeezed or sliced into a 2D array.

More generally, the reason for the Exception

TypeError: Invalid dimensions for image data

is shown here: matplotlib.pyplot.imshow() needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!

You can easily check this with (these checks are done by imshow, this function is only meant to give a more specific message in case it's not a valid input):

from __future__ import print_function
import numpy as np

def valid_imshow_data(data):
    data = np.asarray(data)
    if data.ndim == 2:
        return True
    elif data.ndim == 3:
        if 3 <= data.shape[2] <= 4:
            return True
        else:
            print('The "data" has 3 dimensions but the last dimension '
                  'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
                  ''.format(data.shape[2]))
            return False
    else:
        print('To visualize an image the data must be 2 dimensional or '
              '3 dimensional, not "{}".'
              ''.format(data.ndim))
        return False

In your case:

>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False

The np.asarray is what is done internally by matplotlib.pyplot.imshow so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list) it's necessary.

In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()

import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0)  # or axis=1
plt.imshow(a)
plt.show()

or just use something that accepts 1D arrays like plot:

a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()

It is faster to slice the string twice, like this:

function spliceSlice(str, index, count, add) {
  // We cannot pass negative indexes directly to the 2nd slicing operation.
  if (index < 0) {
    index = str.length + index;
    if (index < 0) {
      index = 0;
    }
  }

  return str.slice(0, index) + (add || "") + str.slice(index + count);
}

than using a split followed by a join (Kumar Harsh's method), like this:

function spliceSplit(str, index, count, add) {
  var ar = str.split('');
  ar.splice(index, count, add);
  return ar.join('');
}

Here's a jsperf that compares the two and a couple other methods. (jsperf has been down for a few months now. Please suggest alternatives in comments.)

Although the code above implements functions that reproduce the general functionality of splice, optimizing the code for the case presented by the asker (that is, adding nothing to the modified string) does not change the relative performance of the various methods.

I don't think Facebook's Open Graph Object i.e. "og_object" provides anything more than comment_count & share_count for a URL. Try this; replace $YOUR_URL with the URL and $ACCESS_TOKEN with your access token in the below link https://graph.facebook.com/v2.5/$YOUR_URL?access_token=$ACCESS_TOKEN

For example:

https://graph.facebook.com/v2.5/http://espn.go.com/nfl/story/_/id/14424066/handing-holiday-gifts-all-32-nfl-teams-nfl?access_token=$ACCESS_TOKEN

{
  og_object: {
    id: "956517601094822",
    description: "Naughty or nice, every NFL team deserves something for Christmas. So in lieu of Santa Claus, Bill Barnwell is here to distribute some gifts.",
    title: "Barnwell: Handing out holiday gifts to all 32 teams",
    type: "article",
    updated_time: "2015-12-23T17:20:55+0000",
    url: "http://espn.go.com/nfl/story/_/id/14424066"
  },
  share: {
    comment_count: 0,
    share_count: 354
  },
  id: "http://espn.go.com/nfl/story/_/id/14424066/handing-holiday-gifts-all-32-nfl-teams-nfl"
}

Also, if you try to get likes, you would get the following error https://graph.facebook.com/http://rottentomatoes.com?fields=likes&summary=1&access_token=$ACCESS_TOKEN

{
  error: {
    message: "(#100) Tried accessing nonexisting field (likes) on node type (URL)",
    type: "OAuthException",
    code: 100,
    fbtrace_id: "H+KksDn+mCf"
  }
}

You are making it complicated. string is already nullable. You don't need to make it more nullable. Take out the ? on the property type.

Here's something quick that also works with file:// URLs.

I came up with this one-liner:

[((1!=location.href.split(location.href.split("/").pop())[0].length?location.href.split(location.href.split("/").pop())[0]:(location.protocol,location.protocol+"//" + location.host+"/"))).replace(location.protocol+"//"+location.protocol+"//"+location.protocol+"://")]

Let's face it: php does NOT have a simple out of the box function to properly handle every array sort scenario.

This routine is intuitive, which means faster debugging and maintenance:

// automatic population of array
$tempArray = array();
$annotations = array();
// ... some code
// SQL $sql retrieves result array $result 
// $row[0] is the ID, but is populated out of order (comes from 
// multiple selects populating various dimensions for the same DATE 
// for example
while($row = mysql_fetch_array($result)) {
    $needle = $row[0];
    arrayIndexes($needle);  // create a parallel array with IDs only
    $annotations[$needle]['someDimension'] = $row[1]; // whatever
}
asort($tempArray);
foreach ($tempArray as $arrayKey) {
    $dataInOrder = $annotations[$arrayKey]['someDimension']; 
    // .... more code
}

function arrayIndexes ($needle) {
    global $tempArray;
    if (!in_array($needle,$tempArray)) {
        array_push($tempArray,$needle);
    }
}

BEGIN TRY
    INSERT INTO YourTable (col1, col2) VALUES (@val1, @val2)
END TRY
BEGIN CATCH
    --print or insert into error log or return param or etc...
    PRINT '@val1='+ISNULL(CONVERT(varchar,@val1),'')
    PRINT '@val2='+ISNULL(CONVERT(varchar,@val2),'')
END CATCH

Check this PowerShell Which.

The code provided there suggests this:

($Env:Path).Split(";") | Get-ChildItem -filter notepad.exe

<?php
session_start();

$message1 = "A message";
$message2 = "Another message";

$_SESSION['firstMessage'] = $message1;
$_SESSION['secondMessage'] = $message2; 
?>

Stores the sessions on page 1 then on page 2 do

<?php
session_start();

echo $_SESSION['firstMessage'];
echo $_SESSION['secondMessage'];
?>

The simple approach (gcc -dM -E - < /dev/null) works fine for gcc but fails for g++. Recently I required a test for a C++11/C++14 feature. Recommendations for their corresponding macro names are published at https://isocpp.org/std/standing-documents/sd-6-sg10-feature-test-recommendations. But:

g++ -dM -E - < /dev/null | fgrep __cpp_alias_templates

always fails, because it silently invokes the C-drivers (as if invoked by gcc). You can see this by comparing its output against that of gcc or by adding a g++-specific command line option like (-std=c++11) which emits the error message cc1: warning: command line option ‘-std=c++11’ is valid for C++/ObjC++ but not for C.

Because (the non C++) gcc will never support "Templates Aliases" (see http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2258.pdf) you must add the -x c++ option to force the invocation of the C++ compiler (Credits for using the -x c++ options instead of an empty dummy file go to yuyichao, see below):

g++ -dM -E -x c++ /dev/null | fgrep __cpp_alias_templates

There will be no output because g++ (revision 4.9.1, defaults to -std=gnu++98) does not enable C++11-features by default. To do so, use

g++ -dM -E -x c++ -std=c++11 /dev/null | fgrep __cpp_alias_templates

which finally yields

#define __cpp_alias_templates 200704

noting that g++ 4.9.1 does support "Templates Aliases" when invoked with -std=c++11.

Keyup should suffice if paired with HTML5 input validation/pattern attribute. So, create a pattern (regex) to validate the input and act upon the .checkValidity() status. Something like below could work. In your case you would want a regex to match length. My solution is in use / demo-able online here.

<input type="text" pattern="[a-zA-Z]+" id="my-input">

var myInput = document.getElementById = "my-input";

myInput.addEventListener("keyup", function(){
  if(!this.checkValidity() || !this.value){
    submitButton.disabled = true;
  } else {
    submitButton.disabled = false;
  }
});

I remember reading that there are 2 kinds of Switch statements in Java bytecode. (I think it was in 'Java Performance Tuning' One is a very fast implementation which uses the switch statement's integer values to know the offset of the code to be executed. This would require all integers to be consecutive and in a well-defined range. I'm guessing that using all the values of an Enum would fall in that category too.

I agree with many other posters though... it may be premature to worry about this, unless this is very very hot code.

You can identify the encoding used for the file (in this case sql file) using an editor (I used Visual studio code). Once you open the file, it shows you the encoding of the file at the lower right corner on the editor.

encoding

I had this issue when I was trying to check-in a file that was encoded UTF-BOM (originating from a non-windows machine) that had special characters appended to individual string characters

You can change the encoding of your file as follows:

In the bottom bar of VSCode, you'll see the label UTF-8 With BOM. Click it. A popup opens. Click Save with encoding. You can now pick a new encoding for that file (UTF-8)

In addition to psparrow's answer if you need to add an index to your temporary table do:

CREATE TEMPORARY TABLE IF NOT EXISTS 
  temp_table ( INDEX(col_2) ) 
ENGINE=MyISAM 
AS (
  SELECT col_1, coll_2, coll_3
  FROM mytable
)

It also works with PRIMARY KEY

You can use splash screen in your first loading Activity like this:

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);

        Thread welcomeThread = new Thread() {

            @Override
            public void run() {
                try {
                    super.run();
                    sleep(10000);  //Delay of 10 seconds
                } catch (Exception e) {

                } finally {

                    Intent i = new Intent(SplashActivity.this,
                            MainActivity.class);
                    startActivity(i);
                    finish();
                }
            }
        };
        welcomeThread.start();
    }

Hope this code helps you.

.parent { text-align: center; }
.parent > .child { margin: 0 auto; width: 900px; }

There's a 'cheap and dirty' trick that I have used... shhhh don't tell anyone. If you output tab delimited text and make the file name *.xls then Excel opens it without objection, question or warning. So just crank the data out into a text file with tab delimitation and you can open it with Excel or Open Office.

As suggested by Mark Ransom, I found the right encoding for that problem. The encoding was "ISO-8859-1", so replacing open("u.item", encoding="utf-8") with open('u.item', encoding = "ISO-8859-1") will solve the problem.

As far as I can see, all other answers so far used a collector to add elements to an existing stream. However, there's a shorter solution, and it works for both sequential and parallel streams. You can simply use the method forEachOrdered in combination with a method reference.

List<String> source = ...;
List<Integer> target = ...;

source.stream()
      .map(String::length)
      .forEachOrdered(target::add);

The only restriction is, that source and target are different lists, because you are not allowed to make changes to the source of a stream as long as it is processed.

Note that this solution works for both sequential and parallel streams. However, it does not benefit from concurrency. The method reference passed to forEachOrdered will always be executed sequentially.

Also, would I be right in concluding that a list comprehension is the most efficient way to do this?

Maybe. List comprehensions are not inherently computationally efficient. It is still running in linear time.

From my personal experience: I have significantly reduced computation time when dealing with large data sets by replacing list comprehensions (specifically nested ones) with for-loop/list-appending type structures you have above. In this application I doubt you will notice a difference.

Actually, the internal behavior is translating the anonymous object to a dictionary. So what I do in these scenarios is go for a dictionary:

@{
  var htmlAttributes = new Dictionary<string, object>
  {
    { "class" , "form-control"},
    { "placeholder", "Why?" }        
  };
  if (Model.IsDisabled)
  {
    htmlAttributes.Add("disabled", "disabled");
  }
}
@Html.EditorFor(m => m.Description, new { htmlAttributes = htmlAttributes })

Or, as Stephen commented here:

@Html.EditorFor(m => m.Description,
    Model.IsDisabled ? (object)new { disabled = "disabled" } : (object)new { })

This is actually a gaping hole in the C# language. There is no way to define a string that cannot be null. This causes problems as simple as the one you are describing, which forces programmers to make a decision they shouldn't have to make, since in many cases NULL and String.Empty mean the same thing. That, in turn, can later force other programmers to have to handle both NULL and String.Empty, which is annoying.

A bigger problem is that databases allow you to define fields that map to a C# string, but database fields can be defined as NOT NULL. So, there is no way to accurately represent, say, a varchar( 100 ) NOT NULL field in SQL Server using a C# type.

Other languages, such as Spec #, do allow this.

In my opinion, C#'s inability to define a string that doesn't allow null is just as bad as its previous inability to define an int that does allow null.

To completely answer your question: I always use empty string for default initialization because it is more similar to how database data types work. (Edit: This statement was very unclear. It should read "I use empty string for default initialization when NULL is a superfluous state, much in the same way I set up a database column as NOT NULL if NULL would be a superfluous state. Similarly, many of my DB columns are set up as NOT NULL, so when I bring those into a C# string, the string will be empty or have a value, but will never be NULL. In other words, I only initialize a string to NULL if null has a meaning that is distinct from the meaning of String.Empty, and I find that case to be less than common (but people here have given legitimate examples of this case).")

THE ANSWER: The problem was all of the posts for such an issue were related to older kerberos and IIS issues where proxy credentials or AllowNTLM properties were helping. My case was different. What I have discovered after hours of picking worms from the ground was that somewhat IIS installation did not include Negotiate provider under IIS Windows authentication providers list. So I had to add it and move up. My WCF service started to authenticate as expected. Here is the screenshot how it should look if you are using Windows authentication with Anonymous auth OFF.

You need to right click on Windows authentication and choose providers menu item.

Hope this helps to save some time.

This is almost identical to how Karl Shifflet demonstrated a RelayCommand, where Execute fires a predetermined Action<T>. A top-notch solution, if you ask me.

public class RelayCommand : ICommand
{
    private readonly Predicate<object> _canExecute;
    private readonly Action<object> _execute;

    public RelayCommand(Predicate<object> canExecute, Action<object> execute)
    {
        _canExecute = canExecute;
        _execute = execute;
    }

    public event EventHandler CanExecuteChanged
    {
        add => CommandManager.RequerySuggested += value;
        remove => CommandManager.RequerySuggested -= value;
    }

    public bool CanExecute(object parameter)
    {
        return _canExecute(parameter);
    }

    public void Execute(object parameter)
    {
        _execute(parameter);
    }
}

This could then be used as...

public class MyViewModel
{
    private ICommand _doSomething;
    public ICommand DoSomethingCommand
    {
        get
        {
            if (_doSomething == null)
            {
                _doSomething = new RelayCommand(
                    p => this.CanDoSomething,
                    p => this.DoSomeImportantMethod());
            }
            return _doSomething;
        }
    }
}

this will also work, if you like

 xcopy  C:\Test\Log "c:\Test\Backup-%date:~4,2%-%date:~7,2%-%date:~10,4%_%time:~0,2%%time:~3,2%" /s /i
 del C:\Test\Log

It's looking like Firefox and Opera (tested on mac as well) don't like the cross domainness of this (but Safari is fine with it).

You might have to call a local server side code to curl the remote page.

You can call ViewController this way, If you want with NavigationController

1.In current Screen : Load new screen

VerifyExpViewController *addProjectViewController = [[VerifyExpViewController alloc] init];
[self.navigationController pushViewController:addProjectViewController animated:YES];

2.1 In Loaded View : add below in .h file

@interface VerifyExpViewController : UIViewController <UINavigationControllerDelegate>

2.2 In Loaded View : add below in .m file

  @implementation VerifyExpViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.navigationController.delegate = self;
    [self setNavigationBar];
}
-(void)setNavigationBar
{
    self.navigationController.navigationBar.backgroundColor = [UIColor clearColor];
    self.navigationController.navigationBar.translucent = YES;
    [self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"B_topbar.png"] forBarMetrics:UIBarMetricsDefault];
    self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName: [UIColor whiteColor]};
    self.navigationItem.hidesBackButton = YES;
    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"Btn_topback.png"] style:UIBarButtonItemStylePlain target:self action:@selector(onBackButtonTap:)];
    self.navigationItem.leftBarButtonItem.tintColor = [UIColor lightGrayColor];
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"Save.png"] style:UIBarButtonItemStylePlain target:self action:@selector(onSaveButtonTap:)];
    self.navigationItem.rightBarButtonItem.tintColor = [UIColor lightGrayColor];
}

-(void)onBackButtonTap:(id)sender
{
    [self.navigationController popViewControllerAnimated:YES];
}
-(IBAction)onSaveButtonTap:(id)sender
{
    //todo for save button
}

@end

Hope this will be useful for someone there :)

Use chooseOkOnNextConfirmation() to dismiss the alert and getAlert() to verify that it has been shown (and optionally grab its text for verification).

selenium.chooseOkOnNextConfirmation();  // prepares Selenium to handle next alert
selenium.click(locator);
String alertText = selenium.getAlert(); // verifies that alert was shown
assertEquals("This is a popup window", alertText);
...

TLDR for people comming from c++

It's just overloaded operator of ( ) parentheses

So in scala:

class X {
   def apply(param1: Int, param2: Int, param3: Int) : Int = {
     // Do something
   }
}

Is same as this in c++:

class X {
   int operator()(int param1, int param2, int param3) {
      // do something
   }
};

    } 
    else {
        scanner.next();

}
System.out.println(integers);

If you're using Bootstrap 3, you need to change the modal-dialog div and not the modal div like it is shown in the accepted answer. Also, to keep the responsive nature of Bootstrap 3, it's important to write the override CSS using a media query so the modal will be full width on smaller devices.

See this JSFiddle to experiment with different widths.

HTML

<div class="modal fade">
    <div class="modal-dialog custom-class">
        <div class="modal-content">

I had the same problem. Most posted solutions would not work. I ran sfc /scannow and it reported that some errors could not be fixed. To address that problem I ran the command

Dism /Online /Cleanup-Image /RestoreHealth

Ironically, I later found the WAN errors had gone away, the 720 VPN error went away and my VPN worked.

Hard to believe that the WAN errors were corrected by this rather esoteric command, but it's worth a try.

The best solution is not to use the same element for column and panel:

<div class="row">
    <div class="col-md-3">
        <div class="panel" id="gameplay-away-team">Away Team</div>
    </div>
    <div class="col-md-6">
        <div class="panel" id="gameplay-baseball-field">Baseball Field</div>
    </div>
    <div class="col-md-3">
        <div class="panel" id="gameplay-home-team">Home Team</div>
    </div>
</div>

and some more styles:

#gameplay-baseball-field {
  padding-right: 10px;
  padding-left: 10px;
}

You can do it like this:

SELECT * FROM ... WHERE name LIKE 'someone'

(It's not the solution, but in some cases is very convenient)

"The LIKE operator does a pattern matching comparison. The operand to the right contains the pattern, the left hand operand contains the string to match against the pattern. A percent symbol ("%") in the pattern matches any sequence of zero or more characters in the string. An underscore ("_") in the pattern matches any single character in the string. Any other character matches itself or its lower/upper case equivalent (i.e. case-insensitive matching). (A bug: SQLite only understands upper/lower case for ASCII characters. The LIKE operator is case sensitive for unicode characters that are beyond the ASCII range. For example, the expression 'a' LIKE 'A' is TRUE but 'æ' LIKE 'Æ' is FALSE.)."

In addition to the answer of Dyppl, I think it would be nice to place this inside the OnDataContextChanged event:

private void OnDataContextChanged(object sender, DependencyPropertyChangedEventArgs e)
{
    // Unforunately we cannot bind from the viewmodel to the code behind so easily, the dependency property is not available in XAML. (for some reason).
    // To work around this, we create the binding once we get the viewmodel through the datacontext.
    var newViewModel = e.NewValue as MyViewModel;

    var executablePathBinding = new Binding
    {
        Source = newViewModel,
        Path = new PropertyPath(nameof(newViewModel.ExecutablePath))
    };

    BindingOperations.SetBinding(LayoutRoot, ExecutablePathProperty, executablePathBinding);
}

We have also had cases were we just saved the DataContext to a local property and used that to access viewmodel properties. The choice is of course yours, I like this approach because it is more consistent with the rest. You can also add some validation, like null checks. If you actually change your DataContext around, I think it would be nice to also call:

BindingOperations.ClearBinding(myText, TextBlock.TextProperty);

to clear the binding of the old viewmodel (e.oldValue in the event handler).

What kind of data?

data: $('#myForm').serialize() + "&moredata=" + morevalue

The "data" parameter is just a URL encoded string. You can append to it however you like. See the API here.

Here's how you can debug CORS requests using curl.

Sending a regular CORS request using cUrl:

curl -H "Origin: http://example.com" --verbose \
  https://www.googleapis.com/discovery/v1/apis?fields=

The -H "Origin: http://example.com" flag is the third party domain making the request. Substitute in whatever your domain is.

The --verbose flag prints out the entire response so you can see the request and response headers.

The url I'm using above is a sample request to a Google API that supports CORS, but you can substitute in whatever url you are testing.

The response should include the Access-Control-Allow-Origin header.

Sending a preflight request using cUrl:

curl -H "Origin: http://example.com" \
  -H "Access-Control-Request-Method: POST" \
  -H "Access-Control-Request-Headers: X-Requested-With" \
  -X OPTIONS --verbose \
  https://www.googleapis.com/discovery/v1/apis?fields=

This looks similar to the regular CORS request with a few additions:

The -H flags send additional preflight request headers to the server

The -X OPTIONS flag indicates that this is an HTTP OPTIONS request.

If the preflight request is successful, the response should include the Access-Control-Allow-Origin, Access-Control-Allow-Methods, and Access-Control-Allow-Headers response headers. If the preflight request was not successful, these headers shouldn't appear, or the HTTP response won't be 200.

You can also specify additional headers, such as User-Agent, by using the -H flag.

For whom it might concern - I tweaked around with Andreas code in order to get all errors code in a flat object for easier logging errors that might appear.

Please consider:

export function collectErrors(control: AbstractControl): any | null {
  let errors = {};
  let recursiveFunc = (control: AbstractControl) => {
    if (isFormGroup(control)) {
      return Object.entries(control.controls).reduce(
        (acc, [key, childControl]) => {
          const childErrors = recursiveFunc(childControl);
          if (childErrors) {
            if (!isFormGroup(childControl)) {
              errors = { ...errors, [key]: childErrors };
            }
            acc = { ...acc, [key]: childErrors };
          }
          return acc;
        },
        null
      );
    } else {
      return control.errors;
    }
  };
  recursiveFunc(control);
  return errors;
}

Because bootstrap is a jquery plugin so it require Jquery to execute

$('#divId > input, #divId > select, #divId > textarea').serialize();

Based on user @andygjp's answer, its better if you override the base Db.SaveChanges() method and add a function to override any date which does not fall between SqlDateTime.MinValue and SqlDateTime.MaxValue.

Here is the sample code

public class MyDb : DbContext
{
    public override int SaveChanges()
    {
        UpdateDates();
        return base.SaveChanges();
    }

    private void UpdateDates()
    {
        foreach (var change in ChangeTracker.Entries().Where(x => (x.State == EntityState.Added || x.State == EntityState.Modified)))
        {
            var values = change.CurrentValues;
            foreach (var name in values.PropertyNames)
            {
                var value = values[name];
                if (value is DateTime)
                {
                    var date = (DateTime)value;
                    if (date < SqlDateTime.MinValue.Value)
                    {
                        values[name] = SqlDateTime.MinValue.Value;
                    }
                    else if (date > SqlDateTime.MaxValue.Value)
                    {
                        values[name] = SqlDateTime.MaxValue.Value;
                    }
                }
            }
        }
    }
}

I hope this would be helpful either.

The Combinations package is not part of the standard CRAN set of packages, but is rather part of a different repository, omegahat. To install it you need to use

install.packages("Combinations", repos = "http://www.omegahat.org/R")

You might try changing this line in your persistence.xml from

<property name="hbm2ddl.auto" value="create"/>

to:

<property name="hibernate.hbm2ddl.auto" value="update"/>

This is supposed to maintain the schema to follow any changes you make to the Model each time you run the app.

Got this from JavaRanch

The issue seems to be resolved in Python version 3.4.2.

testVar = input("Ask user for something.")

Will work fine.

#fullDiv {
  position: absolute;
  margin: 0;
  padding: 0;
  left: 0;
  top: 0;
  bottom: 0;
  right: 0;
  overflow: hidden; /* or auto or scroll */
}

Good guestion! -- where I have not yet found a satisfying answer for my case, the answer I provide here works for me, but may not be future proof...

If one uses gcc (clang?) and have -Werror and -Wbad-function-cast defined,

int val = (int)pow(10,9);

will result:

error: cast from function call of type 'double' to non-matching type 'int' [-Werror=bad-function-cast]

(for a good reason, overflow and where values are rounded needs to be thought out)

EDIT: 2020-08-30: So, my use case casting the value from function returning double to int, and chose pow() to represent that in place of a private function somewhere. Then I sidestepped thinking pow() more. (See comments more why pow() used below could be problematic...).

After properly thought out (that parameters to pow() are good), int val = pow(10,9); seems to work with gcc 9.2 x86-64 ...

but note:

printf("%d\n", pow(10,4));

may output e.g.

-1121380856

(did for me) where

int i = pow(10,4); printf("%d\n", i);

printed

10000

in one particular case I tried.

#multiplying each element in the list and adding it into an empty list
original = [1, 2, 3]
results = []
for num in original:
    results.append(num*2)# multiply each iterative number by 2 and add it to the empty list.

print(results)

Quoting part of @Jatin answer with some modifications,

use this in your where statement:

    SELECT * FROM .... etc.
        Where 
         REPLACE
        (REPLACE
        (REPLACE
        (REPLACE
        (REPLACE
        (REPLACE
        (REPLACE
        (REPLACE
        (REPLACE
        (REPLACE (Name, '0', ''),
        '1', ''),
        '2', ''),
        '3', ''),
        '4', ''),
        '5', ''),
        '6', ''),
        '7', ''),
        '8', ''),
        '9', '') = P_SEARCH_KEY

To fix this, you need to supply an extra parameter to openssl when you're creating the cert, basically

-sha256 -extfile v3.ext

where v3.ext is a file like so, with %%DOMAIN%% replaced with the same name you use as your Common Name. More info here and over here. Note that typically you'd set the Common Name and %%DOMAIN%% to the domain you're trying to generate a cert for. So if it was www.mysupersite.com, then you'd use that for both.

v3.ext

authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names

[alt_names]
DNS.1 = %%DOMAIN%%

Note: Scripts that address this issue, and create fully trusted ssl certs for use in Chrome, Safari and from Java clients can be found here

Another note: If all you're trying to do is stop chrome from throwing errors when viewing a self signed certificate, you can can tell Chrome to ignore all SSL errors for ALL sites by starting it with a special command line option, as detailed here on SuperUser

111 means connection refused, which in turn means that your mysqld only listens to the localhost interface.

To alter it you may want to look at the bind-address value in the mysqld section of your my.cnf file.

Include this where the imports are on top:

import android.view.WindowManager;

Add this code on OnCreate part:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ....
    getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
}

Well one of the option is to goto your workspace, your project folder, then bin copy and paste the log4j properites file. it would be better to paste the file also in source folder.

Now you may want to know from where to get this file, download smslib, then extract it, then smslib->misc->log4j sample configuration -> log4j here you go.

This what helped,me so just wanted to know.

Then, you can create a python virtualenv (https://pypi.python.org/pypi/virtualenv) and install the package from this virtual environment.

Executing 4 commands in the shell will be enough (insert current release like 16.1.0 for X.X.X):

$ curl --location --output virtualenv-X.X.X.tar.gz https://github.com/pypa/virtualenv/tarball/X.X.X
$ tar xvfz virtualenv-X.X.X.tar.gz
$ python pypa-virtualenv-YYYYYY/src/virtualenv.py my_new_env
$ . my_new_env/bin/activate
(my_new_env)$ pip install package_name

The solution I came up with was to use the publishing feature.

File > Publish to the web...

Then in the URL you can just replace the .../edit path with .../pub

This solves the problem described in the question of breaking up a table with footnotes.

No. As the documentation shows, you can only grant access to one object at a time.

private void fillTextView (int id, String text) {
    TextView tv = (TextView) findViewById(id);
    tv.setText(text);
}

If this is where you're getting the null pointer exception, there was no view found for the id that you passed into findViewById(), and the actual exception is thrown when you try to call a function setText() on null. You should post your XML for R.layout.activity_main, as it's hard to tell where things went wrong just by looking at your code.

More reading on null pointers: What is a NullPointerException, and how do I fix it?

Here you go:

$.inArray('specialword', arr)

This function returns a positive integer (the array index of the given value), or -1 if the given value was not found in the array.

Live demo: http://jsfiddle.net/simevidas/5Gdfc/

You probably want to use this like so:

if ( $.inArray('specialword', arr) > -1 ) {
    // the value is in the array
}

add this line end of php.ini

openssl.cafile=/opt/lampp/share/curl/curl-ca-bundle.crt

LastLogon is the last time that the user logged into whichever domain controller you happen to have been load balanced to at the moment that you ran the GET-ADUser cmdlet, and is not replicated across the domain. You really should use LastLogonTimestamp if you want the time the last user logged in to any domain controller in your domain.

As Constructor should be at the starting of the Class , you are facing the above issue . So, you can either change the name or if you want to use it as a constructor just copy the method at the beginning of the class.

There is a limitation in SQL Server (up till 2008 R2) that varchar(MAX) and nvarchar(MAX) (and several other types like text, ntext ) cannot be used in indices. You have 2 options:
1. Set a limited size on the key field ex. nvarchar(100)
2. Create a check constraint that compares the value with all the keys in the table. The condition is:

([dbo].[CheckKey]([key])=(1))

and [dbo].[CheckKey] is a scalar function defined as:

CREATE FUNCTION [dbo].[CheckKey]
(
    @key nvarchar(max)
)
RETURNS bit
AS
BEGIN
    declare @res bit
    if exists(select * from key_value where [key] = @key)
        set @res = 0
    else
        set @res = 1

    return @res
END

But note that a native index is more performant than a check constraint so unless you really can't specify a length, don't use the check constraint.

My inquiry is this. When does one use #import and when does one use @class?

Simple answer: You #import or #include when there is a physical dependency. Otherwise, you use forward declarations (@class MONClass, struct MONStruct, @protocol MONProtocol).

Here are some common examples of physical dependence:

• Any C or C++ value (a pointer or reference is not a physical dependency). If you have a CGPoint as an ivar or property, the compiler will need to see the declaration of CGPoint.
• Your superclass.
• A method you use.

Sometimes if I use a @class declaration, I see a common compiler warning such as the following: "warning: receiver 'FooController' is a forward class and corresponding @interface may not exist."

The compiler's actually very lenient in this regard. It will drop hints (such as the one above), but you can trash your stack easily if you ignore them and don't #import properly. Although it should (IMO), the compiler does not enforce this. In ARC, the compiler is more strict because it is responsible for reference counting. What happens is the compiler falls back on a default when it encounters an unknown method which you call. Every return value and parameter is assumed to be id. Thus, you ought to eradicate every warning from your codebases because this should be considered physical dependence. This is analogous to calling a C function which is not declared. With C, parameters are assumed to be int.

The reason you would favor forward declarations is that you can reduce your build times by factors because there is minimal dependence. With forward declarations, the compiler sees there is a name, and can correctly parse and compile the program without seeing the class declaration or all of its dependencies when there is no physical dependency. Clean builds take less time. Incremental builds take less time. Sure, you will end up spending a little more time making sure the all the headers you need are visible to every translation as a consequence, but this pays off in reduced build times quickly (assuming your project is not tiny).

If you use #import or #include instead, you're throwing a lot more work at the compiler than is necessary. You're also introducing complex header dependencies. You can liken this to a brute-force algorithm. When you #import, you're dragging in tons of unnecessary information, which requires a lot of memory, disk I/O, and CPU to parse and compile the sources.

ObjC is pretty close to ideal for a C based language with regards to dependency because NSObject types are never values -- NSObject types are always reference counted pointers. So you can get away with incredibly fast compile times if you structure your program's dependencies appropriately and forward where possible because there is very little physical dependence required. You can also declare properties in the class extensions to further minimize dependence. That's a huge bonus for large systems -- you would know the difference it makes if you have ever developed a large C++ codebase.

Therefore, my recommendation is to use forwards where possible, and then to #import where there is physical dependence. If you see the warning or another which implies physical dependence -- fix them all. The fix is to #import in your implementation file.

As you build libraries, you will likely classify some interfaces as a group, in which case you would #import that library where physical dependence is introduced (e.g. #import <AppKit/AppKit.h>). This can introduce dependence, but the library maintainers can often handle the physical dependencies for you as needed -- if they introduce a feature, they can minimize the impact it has on your builds.

I found the following article which worked great for me and details the use of the following:

var load_this_javascript = function() { 
  // do some things 
}
$(document).ready(load_this_javascript)
$(window).bind('page:change', load_this_javascript)

$("button").click(function() {
    alert(this.id);
});

If it gets into the selinux arena you've got a much more complicated issue. It's not a good idea to remove the selinux protection but to embrace it and use the tools that were designed to manage it.

If you are serving content out of /var/www/abc, you can verify the selinux permissions with a Z appended to the normal ls -l command. i.e. ls -laZ will give the selinux context.

To add a directory to be served by selinux you can use the semanage command like this. This will change the label on /var/www/abc to httpd_sys_content_t

semanage fcontext -a -t httpd_sys_content_t /var/www/abc

this will update the label for /var/www/abc

restorecon /var/www/abc 

This answer was taken from unixmen and modified to fit this question. I had been searching for this answer for a while and finally found it so felt like I needed to share somewhere. Hope it helps someone.

This code should do the trick:

        string strFinalPath = string.Empty;
        string normalizedFirstPath = Path1.TrimEnd(new char[] { '\\' });
        string normalizedSecondPath = Path2.TrimStart(new char[] { '\\' });
        strFinalPath =  Path.Combine(normalizedFirstPath, normalizedSecondPath);
        return strFinalPath;

You need to leverage the @ViewChild decorator to reference the child component from the parent one by injection:

import { Component, ViewChild } from 'angular2/core';  

(...)

@Component({
  selector: 'my-app',
  template: `
    <h1>My First Angular 2 App</h1>
    <child></child>
    <button (click)="submit()">Submit</button>
  `,
  directives:[App]
})
export class AppComponent { 
  @ViewChild(Child) child:Child;

  (...)

  someOtherMethod() {
    this.searchBar.someMethod();
  }
}

Here is the updated plunkr: http://plnkr.co/edit/mrVK2j3hJQ04n8vlXLXt?p=preview.

You can notice that the @Query parameter decorator could also be used:

export class AppComponent { 
  constructor(@Query(Child) children:QueryList<Child>) {
    this.childcmp = children.first();
  }

  (...)
}

String str = "abc";  // or anything else

// Stores strings of integer representations in sequence
StringBuilder sb = new StringBuilder();
for (char c : str.toCharArray())
    sb.append((int)c);

 // store ascii integer string array in large integer
BigInteger mInt = new BigInteger(sb.toString());
System.out.println(mInt);

This answer is similar to that provided by @tanemaki, but uses a lambda expression instead of scipy stats.

df = pd.DataFrame(np.random.randn(100, 3), columns=list('ABC'))

df[df.apply(lambda x: np.abs(x - x.mean()) / x.std() < 3).all(axis=1)]

To filter the DataFrame where only ONE column (e.g. 'B') is within three standard deviations:

df[((df.B - df.B.mean()) / df.B.std()).abs() < 3]

See here for how to apply this z-score on a rolling basis: Rolling Z-score applied to pandas dataframe

In this case you use -1.

Handy oneliner:

$csv = array_map('str_getcsv', file('data.csv'));

the padding in the TD works if you want the space to have the same background color as the td

in my case, requirement was for white space between header row and whatever was above it

by applying this styling to a single cell, i was able to get the desired separation. It was not necessary to add it to all cells... Arguably not the MOST elegant, but possibly more elegant than separator rows.

<td colspan="10"> 
    <div class="HeaderRow" 
         style="margin-top:10px;">
            <%# Eval("VendorName")%>
     </div>
</td>  

1) Your existing web.config: you have declared rewrite map .. but have not created any rules that will use it. RewriteMap on its' own does absolutely nothing.

2) Below is how you can do it (it does not utilise rewrite maps -- rules only, which is fine for small amount of rewrites/redirects):

This rule will do SINGLE EXACT rewrite (internal redirect) /page to /page.html. URL in browser will remain unchanged.

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRewrite" stopProcessing="true">
                <match url="^page$" />
                <action type="Rewrite" url="/page.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

This rule #2 will do the same as above, but will do 301 redirect (Permanent Redirect) where URL will change in browser.

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRedirect" stopProcessing="true">
                <match url="^page$" />
                <action type="Redirect" url="/page.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

Rule #3 will attempt to execute such rewrite for ANY URL if there are such file with .html extension (i.e. for /page it will check if /page.html exists, and if it does then rewrite occurs):

<system.webServer>
    <rewrite>
        <rules>
            <rule name="DynamicRewrite" stopProcessing="true">
                <match url="(.*)" />
                <conditions>
                    <add input="{REQUEST_FILENAME}\.html" matchType="IsFile" />
                </conditions>
                <action type="Rewrite" url="/{R:1}.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

    display: inline;
}
div {
    position: relative;
    float:right;
    top: 0;
    right: 0;

}

Lets try the example

     ArrayList<String> firstArrayList = new ArrayList<>();
            firstArrayList.add("One");
            firstArrayList.add("Two");
            firstArrayList.add("Three");
            firstArrayList.add("Four");
            firstArrayList.add("Five");
            firstArrayList.add("Six");
            //copy array list content into another array list
             ArrayList<String> secondArrayList=new ArrayList<>();
            secondArrayList.addAll(firstArrayList);
            //print all the content of array list
            Iterator itr = secondArrayList.iterator();
            while (itr.hasNext()) {
                System.out.println(itr.next());
            }

In print output as below

One
Two
Three
Four
Five
Six

We can also do by using clone() method for which is used to create exact copy

for that try you can try as like

 **ArrayList<String>secondArrayList = (ArrayList<String>) firstArrayList.clone();**
    And then print by using iterator
      **Iterator itr = secondArrayList.iterator();
                while (itr.hasNext()) {
                    System.out.println(itr.next());
                }**

This is a copy of my answer to a similar post on SuperUser:

Option 1 - Set VSLauncher.exe and DevEnv.exe to always run as admin

To have Visual Studio always run as admin when opening any .sln file:

1. Navigate to C:\Program Files (x86)\Common Files\Microsoft Shared\MSEnv\VSLauncher.exe.
2. Right-click on VSLauncher.exe and choose Troubleshoot compatibility.
3. Choose Troubleshoot program.
4. Check off The program requires additional permissions and hit Next.
5. Click the Test the program... button to launch VS.
6. Click Next, then hit Yes, save these settings for this program, and then the close buton.

To have Visual Studio always run as an admin when just opening visual studio directly, do the same thing to the DevEnv.exe file(s). These file are located at:

Visual Studio 2010

C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe

Visual Studio 2012

C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe

Visual Studio 2013

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\devenv.exe

Visual Studio 2015

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe

Visual Studio 2017

C:\Program Files (x86)\Microsoft Visual Studio\2017\[VS SKU]\Common7\IDE\devenv.exe

Option 2 - Use VSCommands extension for Visual Studio

Install the free VSCommands extension for Visual Studio (it's in the Visual Studio Extensions Gallery) and then configure it to always have Visual Studio start with admin privileges by going to Tools -> VSCommands -> Options -> IDE Enhancements -> General and check off Always start Visual Studio with elevated permissions and click the Save button.

Note: VSCommands is not currently available for VS 2015, but their site says they are working on updating it to support VS 2015.

My Opinion

I prefer Option 2 because:

• it also allows you to easily turn off this functionality.
• VSCommands comes with lots of other great features so I always have it installed anyways.
• it's just easier to do than option 1.

&& ; || are logical operators.... short circuit

& ; | are boolean logical operators.... Non-short circuit

Moving to differences in execution on expressions. Bitwise operators evaluate both sides irrespective of the result of left hand side. But in the case of evaluating expressions with logical operators, the evaluation of the right hand expression is dependent on the left hand condition.

For Example:

int i = 25;
int j = 25;
if(i++ < 0 && j++ > 0)
    System.out.println("OK");
System.out.printf("i = %d ; j = %d",i,j);

This will print i=26 ; j=25, As the first condition is false the right hand condition is bypassed as the result is false anyways irrespective of the right hand side condition.(short circuit)

int i = 25;
int j = 25;
if(i++ < 0 & j++ > 0)
    System.out.println("OK");
System.out.printf("i = %d ; j = %d",i,j);

But, this will print i=26; j=26,

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Variant

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    rowNum = Application.Match(aNumber, rng, 0)

    If Not IsError(rowNum) Then
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

Instead of using onload, use Angular's ng-init.

<article id="showSelector" ng-controller="CinemaCtrl" ng-init="myFunction()">

Note: This requires that myFunction is a property of the CinemaCtrl scope.

The simplest way to extract a number from a string is to use regular expressions and findall.

>>> import re
>>> s = '300 gm'
>>> re.findall('\d+', s)
['300']
>>> s = '300 gm 200 kgm some more stuff a number: 439843'
>>> re.findall('\d+', s)
['300', '200', '439843']

It might be that you need something more complex, but this is a good first step.

Note that you'll still have to call int on the result to get a proper numeric type (rather than another string):

>>> map(int, re.findall('\d+', s))
[300, 200, 439843]

In case anyone wants to have a responsive flexbox with percentages (%) it is much easier for media queries.

flex-basis: 25%;

This will be a lot smoother when testing.

// VARIABLES

Use a binding, like in this example:

<a href="#new-search" data-bind="click:SearchManager.bind($data,'1')">
  Search Manager
</a>

var ViewModelStructure = function () {
    var self = this;
    this.SearchManager = function (search) {
        console.log(search);
    };
}();

replace contentType : "application/x-www-form-urlencoded", by dataType : "text" as wildfly 11 doesn't support mentioned contenttype..

Use beforeSend:

$.ajax({
         url: "http://localhost/PlatformPortal/Buyers/Account/SignIn",
         data: { signature: authHeader },
         type: "GET",
         beforeSend: function(xhr){xhr.setRequestHeader('X-Test-Header', 'test-value');},
         success: function() { alert('Success!' + authHeader); }
      });

By the time the image is loaded, the renderer has already drawn the scene, hence it is too late. The solution is to change

texture = THREE.ImageUtils.loadTexture('crate.gif'),

into

texture = THREE.ImageUtils.loadTexture('crate.gif', {}, function() {
    renderer.render(scene);
}),

All of the above answers ignore the fact that you mention you have no window or navigator :-)

Then I openede developer console in IE11

and thats where it says

Object not found and needs to be re-evaluated.

and navigator, window, console, none of them exist and need to be re-evaluated. I've had that in emulation. just close and open the console a few times.

Here is the solution which worked for me.

OUTPUT: State of Cart Widget is updated, upon addition of items.

Create a globalKey for the widget you want to update by calling the trigger from anywhere

final GlobalKey<CartWidgetState> cartKey = GlobalKey();

Make sure it's saved in a file have global access such that, it can be accessed from anywhere. I save it in globalClass where is save commonly used variables through the app's state.

class CartWidget extends StatefulWidget {

  CartWidget({Key key}) : super(key: key);
  @override
  CartWidgetState createState() => CartWidgetState();
}

class CartWidgetState extends State<CartWidget> {
  @override
  Widget build(BuildContext context) {
    //return your widget
    return Container();
  }
}

Call your widget from some other class.

class HomeScreen extends StatefulWidget {

  HomeScreen ({Key key}) : super(key: key);
  @override
  HomeScreenState createState() => HomeScreen State();
}

class HomeScreen State extends State<HomeScreen> {
  @override
  Widget build(BuildContext context) {
    return ListView(
              children:[
                 ChildScreen(), 
                 CartWidget(key:cartKey)
              ]
            );
  }
}



class ChildScreen extends StatefulWidget {

  ChildScreen ({Key key}) : super(key: key);
  @override
  ChildScreenState createState() => ChildScreen State();
}

class ChildScreen State extends State<ChildScreen> {
  @override
  Widget build(BuildContext context) {
    return InkWell(
              onTap: (){
                // This will update the state of your inherited widget/ class
                if (cartKey.currentState != null)
                    cartKey.currentState.setState(() {});
              },
              child: Text("Update The State of external Widget"),
           );
  }
}

Considering that you have

$replaced = array('1' => 'value1', '4' => 'value4');
$replacement = array('4' => 'value2', '6' => 'value3');

Doing $merge = $replacement + $replaced; will output:

Array('4' => 'value2', '6' => 'value3', '1' => 'value1');

The first array from sum will have values in the final output.

Doing $merge = $replaced + $replacement; will output:

Array('1' => 'value1', '4' => 'value4', '6' => 'value3');

ps -ef | grep tomcat | awk '{print $2}' | xargs kill -9

https://gist.github.com/nrshrivatsan/1d2ea4fcdcb9d1857076

Part 1

ps -ef | grep tomcat => Get all processes with tomcat grep

Part 2

Once we have process details, we pipe it into the part 2 of the script

awk '{print $2}' | xargs kill -9 => Get the second column [Process id] and kill them with -9 option

Hope this helps.

in Eclips the Package Explorer Right click on any viewable project and select Show in -> Project Explorer

Package Explorer -> Right click -> Show in ->Project Explorer

you should be able to see all the imported projects in your Eclipse workspace

You could use the ngSwitch directive:

  <div ng-switch on="selection" >
    <div ng-switch-when="settings">Settings Div</div>
    <span ng-switch-when="home">Home Span</span>
    <span ng-switch-default>default</span>
  </div>

If you don't want the DOM to be loaded with empty divs, you need to create your custom directive using $http to load the (sub)templates and $compile to inject it in the DOM when a certain condition has reached.

This is just an (untested) example. It can and should be optimized:

HTML:

<conditional-template ng-model="element" template-url1="path/to/partial1" template-url2="path/to/partial2"></div>

Directive:

app.directive('conditionalTemplate', function($http, $compile) {
   return {
      restrict: 'E',
      require: '^ngModel',
      link: function(sope, element, attrs, ctrl) {
        // get template with $http
        // check model via ctrl.$viewValue
        // compile with $compile
        // replace element with element.replaceWith()
      }
   };
});

/Users/{user}/Library/Application Support/Sublime Text 2/Packages

Get to it quickly from within Sublime via the menu at Sublime Text 2... Preferences... Browse Packages

Instead of getApplicationContext(), just use ActivityName.this.

Because you wanted to install specific package "I need to install only 1 package for my SF2 distribution (DoctrineFixtures)."

php composer.phar require package/package-name:package-version would be enough

1. The easiest way is to click on that commit and add a tag to that commit. I have included the tag 'last_commit' with this commit

2. Than go to downloads in the left corner of the side nav in bit bucket. Click on download in the left side

3. Now click on tags in the nav bar and download the zip from the UI. Find your tag and download the zip

You always need something like this

html
{
    width: 100%;
    height: 100%;
}

at the top of your css file

By sorting the file with sort first, you can then apply uniq.

It seems to sort the file just fine:
