If you're using SQL Server, one of the best resources is its own Books Online that comes with the install! It's the 1st place I would refer to for ANY SQL Server related topics.

If it's practical "how should I do this?" kind of questions, then StackOverflow would be a better place to ask.

Also, I haven't been back for a while but sqlservercentral.com used to be one of the top SQL Server related sites out there.

I'm guessing - are you trying to create Dialog using.

 getApplicationContext()
 mContext which is passed by activity.

if You displaying dialog non activity class then you have to pass activity as a parameter.

Activity activity=YourActivity.this;

Now it will be work great.

If you find any trouble then let me know.

I'd be more inclined to do it this way, using (optionally) automatic properties and defaults. You haven't suggested that the two fields are part of a data structure, so that's why I chose this way.

You could have the properties on the class and then assign them the usual way. And obviously they may or may not be required, so that's something else too. It's just that this is such nice syntactic sugar.

class MyClass{
    constructor(public Field1:string = "", public Field2:string = "")
    {
        // other constructor stuff
    }
}

var myClass = new MyClass("ASD", "QWE");
alert(myClass.Field1); // voila! statement completion on these properties

If you have an old backup copy of CurrentSettings.vssettings, you can try restoring it.

I had a completely corrupted Visual Studio layout. When I tried to enter debug, I was told that VS had become unstable. When I restarted, my window layout would then be totally screwed. I tried restoring the VS current user settings in the registry from a backup, but that didn't help. However, restoring CurrentSettings.vssettings seems to have cured it.

There seems to be a bunch of binary stuff in there and I can imagine it gets irretrievably corrupted sometimes.

I arrived at this question looking for a way to stream an open ended list of objects onto a System.IO.Stream and read them off the other end, without buffering the entire list before sending. (Specifically I'm streaming persisted objects from MongoDB over Web API.)

@Paul Tyng and @Rivers did an excellent job answering the original question, and I used their answers to build a proof of concept for my problem. I decided to post my test console app here in case anyone else is facing the same issue.

using System;
using System.Diagnostics;
using System.IO;
using System.IO.Pipes;
using System.Threading;
using System.Threading.Tasks;
using Newtonsoft.Json;

namespace TestJsonStream {
    class Program {
        static void Main(string[] args) {
            using(var writeStream = new AnonymousPipeServerStream(PipeDirection.Out, HandleInheritability.None)) {
                string pipeHandle = writeStream.GetClientHandleAsString();
                var writeTask = Task.Run(() => {
                    using(var sw = new StreamWriter(writeStream))
                    using(var writer = new JsonTextWriter(sw)) {
                        var ser = new JsonSerializer();
                        writer.WriteStartArray();
                        for(int i = 0; i < 25; i++) {
                            ser.Serialize(writer, new DataItem { Item = i });
                            writer.Flush();
                            Thread.Sleep(500);
                        }
                        writer.WriteEnd();
                        writer.Flush();
                    }
                });
                var readTask = Task.Run(() => {
                    var sw = new Stopwatch();
                    sw.Start();
                    using(var readStream = new AnonymousPipeClientStream(pipeHandle))
                    using(var sr = new StreamReader(readStream))
                    using(var reader = new JsonTextReader(sr)) {
                        var ser = new JsonSerializer();
                        if(!reader.Read() || reader.TokenType != JsonToken.StartArray) {
                            throw new Exception("Expected start of array");
                        }
                        while(reader.Read()) {
                            if(reader.TokenType == JsonToken.EndArray) break;
                            var item = ser.Deserialize<DataItem>(reader);
                            Console.WriteLine("[{0}] Received item: {1}", sw.Elapsed, item);
                        }
                    }
                });
                Task.WaitAll(writeTask, readTask);
                writeStream.DisposeLocalCopyOfClientHandle();
            }
        }

        class DataItem {
            public int Item { get; set; }
            public override string ToString() {
                return string.Format("{{ Item = {0} }}", Item);
            }
        }
    }
}

Note that you may receive an exception when the AnonymousPipeServerStream is disposed, I ignored this as it isn't relevant to the problem at hand.

The full program working is:

public class main {

    public static void main(String[] args) {

        logicCounter counter1 = new logicCounter();
        counter1.counter("I am trying to make a program on word count which I have partially made and it is giving the correct result but the moment I enter space or more than one space in the string, the result of word count show wrong results because I am counting words on the basis of spaces used. I need help if there is a solution in a way that no matter how many spaces are I still get the correct result. I am mentioning the code below.");
    }
}

public class logicCounter {

    public void counter (String str) {

        String str1 = str;
        boolean space= true;
        int i;

        for ( i = 0; i < str1.length(); i++) {

            if (str1.charAt(i) == ' ') {
                space=true;
            } else {
                i++;
            }
        }

        System.out.println("there are " + i + " letters");
    }
}

For something simple that work for arrays , strings , and objects I builed this function:

function console_testing($var){

    $var = json_encode($var,JSON_UNESCAPED_UNICODE);

    $output = <<<EOT
    <script>
        console.log($var); 
    </script>
EOT;

    echo $output;

}

You mean something like this?

List<object> objects = new List<object>();
var strings = (from o in objects
              select o.ToString()).ToList();

I had to make some changes to make it work, as some things seem to have changed in the meantime:

• xjc would complain that my adapter does not extend XmlAdapter
• some bizarre and unneeded imports were drawn in (org.w3._2001.xmlschema)
• the parsing methods must not be static when extending the XmlAdapter, obviously

Here's a working example, hope this helps (I'm using JodaTime but in this case SimpleDate would be sufficient):

import java.util.Date;
import javax.xml.bind.DatatypeConverter;
import javax.xml.bind.annotation.adapters.XmlAdapter;
import org.joda.time.DateTime;

public class DateAdapter extends XmlAdapter<Object, Object> {
    @Override
    public Object marshal(Object dt) throws Exception {
        return new DateTime((Date) dt).toString("YYYY-MM-dd");
    }

    @Override
        public Object unmarshal(Object s) throws Exception {
        return DatatypeConverter.parseDate((String) s).getTime();
    }
}

In the xsd, I have followed the excellent references given above, so I have included this xml annotation:

<xsd:appinfo>
    <jaxb:schemaBindings>
        <jaxb:package name="at.mycomp.xml" />
    </jaxb:schemaBindings>
    <jaxb:globalBindings>
        <jaxb:javaType name="java.util.Date" xmlType="xsd:date"
              parseMethod="at.mycomp.xml.DateAdapter.unmarshal"
          printMethod="at.mycomp.xml.DateAdapter.marshal" />
    </jaxb:globalBindings>
</xsd:appinfo>

My version of mail does not have --append and it too smart for the echo -e \n-trick (it simply replaces \n with space). It does, however, have -a:

mail -a "Content-type: text/html" -s "Built notification" [email protected] < /var/www/report.html

Because we can not use Where clause with aggregate functions like count(),min(), sum() etc. so having clause came into existence to overcome this problem in sql. see example for having clause go through this link

http://www.sqlfundamental.com/having-clause.php

Chain both class selectors (without a space in between):

.foo.bar {
    /* Styles for element(s) with foo AND bar classes */
}

If you still have to deal with ancient browsers like IE6, be aware that it doesn't read chained class selectors correctly: it'll only read the last class selector (.bar in this case) instead, regardless of what other classes you list.

To illustrate how other browsers and IE6 interpret this, consider this CSS:

* {
    color: black;
}

.foo.bar {
    color: red;
}

Output on supported browsers is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Not selected, black text [3] -->

Output on IE6 is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Selected, red text [2] -->

Footnotes:

• Supported browsers:
  1. Not selected as this element only has class foo.
  2. Selected as this element has both classes foo and bar.
  3. Not selected as this element only has class bar.
     
     
• IE6:
  1. Not selected as this element doesn't have class bar.
  2. Selected as this element has class bar, regardless of any other classes listed.

Alternatively, you could set the .AcceptButton property of your form. Enter will automcatically create a click event.

this.AcceptButton = this.buttonSearch;

After many struggles and to achive a general, flexible and more readable solution, in my case I ended up saving the ORs results into ENV variables and doing the ANDs of those variables.

# RESULT_ONE = A OR B
RewriteRule ^ - [E=RESULT_ONE:False]
RewriteCond ...A... [OR]
RewriteCond ...B...
RewriteRule ^ - [E=RESULT_ONE:True]

# RESULT_TWO = C OR D
RewriteRule ^ - [E=RESULT_TWO:False]
RewriteCond ...C... [OR]
RewriteCond ...D...
RewriteRule ^ - [E=RESULT_TWO:True]

# if ( RESULT_ONE AND RESULT_TWO ) then ( RewriteRule ...something... )
RewriteCond %{ENV:RESULT_ONE} =True
RewriteCond %{ENV:RESULT_TWO} =True
RewriteRule ...something...

Requirements:

• Apache mod_env enabled

Use %0A (URL encoding) instead of \n (C encoding).

This is one of the most commonly asked question to obtain the paginated result and the total number of results simultaneously in single query. I can't explain how I felt when I finally achieved it LOL.

$result = $collection->aggregate(array(
  array('$match' => $document),
  array('$group' => array('_id' => '$book_id', 'date' => array('$max' => '$book_viewed'),  'views' => array('$sum' => 1))),
  array('$sort' => $sort),

// get total, AND preserve the results
  array('$group' => array('_id' => null, 'total' => array( '$sum' => 1 ), 'results' => array( '$push' => '$$ROOT' ) ),
// apply limit and offset
  array('$project' => array( 'total' => 1, 'results' => array( '$slice' => array( '$results', $skip, $length ) ) ) )
))

Result will look something like this:

[
  {
    "_id": null,
    "total": ...,
    "results": [
      {...},
      {...},
      {...},
    ]
  }
]

• To run https functionality or SSL authentication in flask application you first install "pyOpenSSL" python package using:

   pip install pyopenssl
  

• Next step is to create 'cert.pem' and 'key.pem' using following command on terminal :

   openssl req -x509 -newkey rsa:4096 -nodes -out cert.pem -keyout key.pem -days 365
  

• Copy generated 'cert.pem' and 'kem.pem' in you flask application project

• Add ssl_context=('cert.pem', 'key.pem') in app.run()

For example:

    from flask import Flask, jsonify

    app = Flask(__name__)

    @app.route('/')

    def index():

        return 'Flask is running!'


    @app.route('/data')

    def names():

        data = {"names": ["John", "Jacob", "Julie", "Jennifer"]}

        return jsonify(data)

  if __name__ == '__main__':

        app.run(ssl_context=('cert.pem', 'key.pem'))

I know this is old, but I hope this helps someone.

Using regular python sockets I found that you can send and receive information in packets using sendto and recvfrom

# tcp_echo_server.py
import socket

ADDRESS = ''
PORT = 54321

connections = []
host = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host.setblocking(0)
host.bind((ADDRESS, PORT))
host.listen(10)  # 10 is how many clients it accepts

def close_socket(connection):
    try:
        connection.shutdown(socket.SHUT_RDWR)
    except:
        pass
    try:
        connection.close()
    except:
        pass

def read():
    for i in reversed(range(len(connections))):
        try:
            data, sender = connections[i][0].recvfrom(1500)
            return data
        except (BlockingIOError, socket.timeout, OSError):
            pass
        except (ConnectionResetError, ConnectionAbortedError):
            close_socket(connections[i][0])
            connections.pop(i)
    return b''  # return empty if no data found

def write(data):
    for i in reversed(range(len(connections))):
        try:
            connections[i][0].sendto(data, connections[i][1])
        except (BlockingIOError, socket.timeout, OSError):
            pass
        except (ConnectionResetError, ConnectionAbortedError):
            close_socket(connections[i][0])
            connections.pop(i)

# Run the main loop
while True:
    try:
        con, addr = host.accept()
        connections.append((con, addr))
    except BlockingIOError:
        pass

    data = read()
    if data != b'':
        print(data)
        write(b'ECHO: ' + data)
        if data == b"exit":
            break

# Close the sockets
for i in reversed(range(len(connections))):
    close_socket(connections[i][0])
    connections.pop(i)
close_socket(host)

The client is similar

# tcp_client.py
import socket

ADDRESS = "localhost"
PORT = 54321

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((ADDRESS, PORT))
s.setblocking(0)

def close_socket(connection):
    try:
        connection.shutdown(socket.SHUT_RDWR)
    except:
        pass
    try:
        connection.close()
    except:
        pass

def read():
    """Read data and return the read bytes."""
    try:
        data, sender = s.recvfrom(1500)
        return data
    except (BlockingIOError, socket.timeout, AttributeError, OSError):
        return b''
    except (ConnectionResetError, ConnectionAbortedError, AttributeError):
        close_socket(s)
        return b''

def write(data):
    try:
        s.sendto(data, (ADDRESS, PORT))
    except (ConnectionResetError, ConnectionAbortedError):
        close_socket(s)

while True:
    msg = input("Enter a message: ")
    write(msg.encode('utf-8'))

    data = read()
    if data != b"":
        print("Message Received:", data)

    if msg == "exit":
        break

close_socket(s)

Since array literal notation is still valid JSON, you can use JSON.parse() to convert that string into an array, and from there, use it's values.

var test = "[1,2]";
parsedTest = JSON.parse(test); //an array [1,2]

//access like and array
console.log(parsedTest[0]); //1
console.log(parsedTest[1]); //2

I recently discovered an interesting trick that allows to "Split String With String As Delimiter", so I couldn't resist the temptation to post it here as a new answer. Note that "obviously the question wasn't accurate. Firstly, both string1 and string2 can contain spaces. Secondly, both string1 and string2 can contain ampersands ('&')". This method correctly works with the new specifications (posted as a comment below Stephan's answer).

@echo off
setlocal

set "str=string1&with spaces by string2&with spaces.txt"

set "string1=%str: by =" & set "string2=%"
set "string2=%string2:.txt=%"

echo "%string1%"
echo "%string2%"

For further details on the split method, see this post.

Today at midnight. Easy.

$stamp = mktime(0, 0, 0);

Just try like this:

HTML in PHP :

$link_address1 = 'index.php';
echo "<a href='".$link_address1."'>Index Page</a>";

$link_address2 = 'page2.php';
echo "<a href='".$link_address2."'>Page 2</a>";

Easiest way

$link_address1 = 'index.php';
echo "<a href='$link_address1'>Index Page</a>";

$link_address2 = 'page2.php';
echo "<a href='$link_address2'>Page 2</a>";

I don't know why but version 3.6 of DG_Readiness_Tool didn't work for me. After I restarted my laptop problem still persisted. I was looking for solution and finally I came across version 3.7 of the tool and this time problem went away. Here you can find latest powershell script:

DG_Readiness_Tool_v3.7

var top = $('html').offset().top;

should do it.

edit: this is the negative of $(document).scrollTop()

$(this).css("text-align", "center"); should work, make sure 'this' is the element you're actually trying to set the text-align style to.

strip() returns the string after removing leading and trailing whitespace. see doc

In your case, you may want to try replace():

string2 = string1.replace('\n', '')

from datetime import timedelta    
datetime.datetime.now() - datetime.timedelta(0, 900)

Actually 900 is in seconds. Which is equal to 15 minutes. `15*60 = 900`

I get the same error in Chrome after pasting code copied from jsfiddle.

If you select all the code from a panel in jsfiddle and paste it into the free text editor Notepad++, you should be able to see the problem character as a question mark "?" at the very end of your code. Delete this question mark, then copy and paste the code from Notepad++ and the problem will be gone.

In addition to @enyo's answer in checking for files that are still uploading or in the queue, I also created a new function in dropzone.js to check for any files in an ERROR state (ie bad file type, size, etc).

Dropzone.prototype.getErroredFiles = function () {
    var file, _i, _len, _ref, _results;
    _ref = this.files;
    _results = [];
    for (_i = 0, _len = _ref.length; _i < _len; _i++) {
        file = _ref[_i];
        if (file.status === Dropzone.ERROR) {
            _results.push(file);
        }
    }
    return _results;
};

And thus, the check would become:

  if (this.getUploadingFiles().length === 0 && this.getQueuedFiles().length === 0 && this.getErroredFiles().length === 0) {
    doSomething();
  }

After porting several of my libraries to different projects, and having to constantly be changing the top level (statically named) namespace, I've switched to using this small (open source) helper function for defining namespaces.

global_namespace.Define('startpad.base', function(ns) {
    var Other = ns.Import('startpad.other');
    ....
});

Description of the benefits are at my blog post. You can grab the source code here.

One of the benefits I really like is isolation between modules with respect to load order. You can refer to an external module BEFORE it is loaded. And the object reference you get will be filled in when the code is available.

Try to install mysqli and pdo. Put it in terminal:

./configure --with-mysql=/usr/bin/mysql_config  \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd

I am surprised that none of the answers mentioned the insertAdjacentHTML() method. Check it out here. The first parameter is where you want the string appended and takes ("beforebegin", "afterbegin", "beforeend", "afterend"). In the OP's situation you would use "beforeend". The second parameter is just the html string.

Basic usage:

var d1 = document.getElementById('one');
d1.insertAdjacentHTML('beforeend', '<div id="two">two</div>');

Alternatively you could use:

if ($('#navigation a').is(".active")) {
    $(this).parent().addClass("active");
}

Add this in MainActivity.

Intent intent = new Intent(getApplicationContext(), Heightimage.class);
startActivity(intent);

I had this in viewPager and the crash was because any fragment had to have its own tag, duplicate tags or ids for same fragment are not allowed.

Quote: "What does the construct x = x || y mean?"

Assigning a default value.

This means providing a default value of y to x, in case x is still waiting for its value but hasn't received it yet or was deliberately omitted in order to fall back to a default.

If you mean delete every instance of all models, I would use

ActiveRecord::Base.connection.tables.map(&:classify)
  .map{|name| name.constantize if Object.const_defined?(name)}
  .compact.each(&:delete_all)

$foo = 42;
$bar = function($x = 0) use ($foo){
    return $x + $foo;
};
var_dump($bar(10)); // int(52)

UPDATE: there is now support for arrow functions, but i will let for someone that used it more to create the answer

$array  = data();

print_r($array);

I have been playing about with tmux today, trying to customised a little here and there, managed to get battery info displaying on the status right with a ruby script.

Copy the ruby script from http://natedickson.com/blog/2013/04/30/battery-status-in-tmux/ and save it as:

 battinfo.rb in ~/bin

To make it executable make sure to run:

chmod +x ~/bin/battinfo.rb

edit your ~/.tmux.config and include this line

set -g status-right "#[fg=colour155]#(pmset -g batt | ~/bin/battinfo.rb) | #[fg=colour45]%d %b %R"

This can be done fairly easily using a Lombok generated equals and a static EMPTY object:

import lombok.Data;

public class EmptyCheck {
    public static void main(String[] args) {
        User user1 = new User();

        User user2 = new User();
        user2.setName("name");

        System.out.println(user1.isEmpty()); // prints true
        System.out.println(user2.isEmpty()); // prints false
    }

    @Data
    public static class User {
        private static final User EMPTY = new User();

        private String id;
        private String name;
        private int age;

        public boolean isEmpty() {
            return this.equals(EMPTY);
        }
    }
}

Prerequisites:

• Default constructor should not be implemented with custom behavior as that is used to create the EMPTY object
• All fields of the class should have an implemented equals (built-in Java types are usually not a problem, in case of custom types you can use Lombok)

Advantages:

• No reflection involved
• As new fields added to the class, this does not require any maintenance as due to Lombok they will be automatically checked in the equals implementation
• Unlike some other answers this works not just for null checks but also for primitive types which have a non-null default value (e.g. if field is int it checks for 0, in case of boolean for false, etc.)

Obviously using count($arr) > 1 (sizeof is just an alias for count) is the best solution. Depending on the structure of your array, there might be tons of elements but no $array['1'] element.

for me it was because in the 'Authorized redirect URIs' list I've incorrectly put https://developers.google.com/oauthplayground/ instead of https://developers.google.com/oauthplayground (without / at the end).

print scalar grep { defined $_ } @a;

Really have to do this with JS. Here's a solution. I didn't use your class names, but I called the div within the td class name of "full-height" :-) Used jQuery, obviously. Note this was called from jQuery(document).ready(function(){ setFullHeights();}); Also note if you have images, you are going to have to iterate through them first with something like:

function loadedFullHeights(){
var imgCount = jQuery(".full-height").find("img").length;
if(imgCount===0){
    return setFullHeights();
}
var loaded = 0;
jQuery(".full-height").find("img").load(function(){
    loaded++;
    if(loaded ===imgCount){
        setFullHeights()
    }
});

}

And you would want to call the loadedFullHeights() from docReady instead. This is actually what I ended up using just in case. Got to think ahead you know!

function setFullHeights(){
var par;
var height;
var $ = jQuery;
var heights=[];
var i = 0;
$(".full-height").each(function(){
    par =$(this).parent();
    height = $(par).height();
    var tPad = Number($(par).css('padding-top').replace('px',''));
    var bPad = Number($(par).css('padding-bottom').replace('px',''));
    height -= tPad+bPad;
    heights[i]=height;
    i++;
});
for(ii in heights){
    $(".full-height").eq(ii).css('height', heights[ii]+'px');
}

}

None of these answers worked for me. When converting to UTF8, when the encoder encounters a set of bytes it can't convert to UTF8 it will result in a ? substitution which results in data loss. You need to use UTF16:

SELECT
    blobfield,
    CONVERT(blobfield USING utf16),
    CONVERT(CONVERT(blobfield USING utf16), BINARY),
    CAST(blobfield  AS CHAR(10000) CHARACTER SET utf16),
    CAST(CAST(blobfield  AS CHAR(10000) CHARACTER SET utf16) AS BINARY)

You can inspect the binary values in MySQL Workbench. Right click on the field -> Open Value in Viewer-> Binary. When converted back to BINARY the binary values should be the same as the original.

Alternatively, you can just use base-64 which was made for this purpose:

SELECT
    blobfield,
    TO_BASE64(blobfield),
    FROM_BASE64(TO_BASE64(blobfield))

With Swift 5, you may choose one of the three examples shown below in order to solve your problem.

#1. Using String's init(format:_:) initializer

Foundation provides Swift String a init(format:_:) initializer. init(format:_:) has the following declaration:

init(format: String, _ arguments: CVarArg...)

Returns a String object initialized by using a given format string as a template into which the remaining argument values are substituted.

The following Playground code shows how to create a String formatted from Int with at least two integer digits by using init(format:_:):

import Foundation

let string0 = String(format: "%02d", 0) // returns "00"
let string1 = String(format: "%02d", 1) // returns "01"
let string2 = String(format: "%02d", 10) // returns "10"
let string3 = String(format: "%02d", 100) // returns "100"

#2. Using String's init(format:arguments:) initializer

Foundation provides Swift String a init(format:arguments:) initializer. init(format:arguments:) has the following declaration:

init(format: String, arguments: [CVarArg])

Returns a String object initialized by using a given format string as a template into which the remaining argument values are substituted according to the user’s default locale.

The following Playground code shows how to create a String formatted from Int with at least two integer digits by using init(format:arguments:):

import Foundation

let string0 = String(format: "%02d", arguments: [0]) // returns "00"
let string1 = String(format: "%02d", arguments: [1]) // returns "01"
let string2 = String(format: "%02d", arguments: [10]) // returns "10"
let string3 = String(format: "%02d", arguments: [100]) // returns "100"

#3. Using NumberFormatter

Foundation provides NumberFormatter. Apple states about it:

Instances of NSNumberFormatter format the textual representation of cells that contain NSNumber objects and convert textual representations of numeric values into NSNumber objects. The representation encompasses integers, floats, and doubles; floats and doubles can be formatted to a specified decimal position.

The following Playground code shows how to create a NumberFormatter that returns String? from a Int with at least two integer digits:

import Foundation

let formatter = NumberFormatter()
formatter.minimumIntegerDigits = 2

let optionalString0 = formatter.string(from: 0) // returns Optional("00")
let optionalString1 = formatter.string(from: 1) // returns Optional("01")
let optionalString2 = formatter.string(from: 10) // returns Optional("10")
let optionalString3 = formatter.string(from: 100) // returns Optional("100")

You can HashMap<MyHashObject,MyHashObject> instead of HashSet<MyHashObject>.

Calling ContainsKey() on your "reconstructed" MyHashObject will first hashCode()-check the collection, and if a duplicate hashcode is hit, finally equals()-check your "reconstructed" against the original, at which you can retrieve the original using get()

This is O(1) but the downside is you will likely have to override both equals() and hashCode() methods.

All these seem way too complicated and I guess it gets into a debate about what exactly adding "a month" means. Does it mean 30 days? Does it mean from the 1st to the 1st? From the last day to the last day?

If the latter, then adding a month to Feb 27th gets you to March 27th, but adding a month to Feb 28th gets you to March 31st (except in leap years, where it gets you to March 28th). Then subtracting a month from March 30th gets you... Feb 27th? Who knows...

For those looking for a simple solution, just add milliseconds and be done.

function getDatePlusDays(dt, days) {
  return new Date(dt.getTime() + (days * 86400000));
}

or

Date.prototype.addDays = function(days) {
  this = new Date(this.getTime() + (days * 86400000));
};

See also this previous answer which recommends the not keyword

How to check if a list is empty in Python?

It generalizes to more than just lists:

>>> a = ""
>>> not a
True

>>> a = []
>>> not a
True

>>> a = 0
>>> not a
True

>>> a = 0.0
>>> not a
True

>>> a = numpy.array([])
>>> not a
True

Notably, it will not work for "0" as a string because the string does in fact contain something - a character containing "0". For that you have to convert it to an int:

>>> a = "0"
>>> not a
False

>>> a = '0'
>>> not int(a)
True

Once the file object is iterated, it is exausted.

>>> f = open('1.txt', 'w')
>>> f.write('1\n2\n3\n')
>>> f.close()
>>> f = open('1.txt', 'r')
>>> for line in f: print line
...
1

2

3

# exausted, another iteration does not produce anything.
>>> for line in f: print line
...
>>>

Use file.seek (or close/open the file) to rewind the file:

>>> f.seek(0)
>>> for line in f: print line
...
1

2

3

you'd use any of these:

JSTL c:forEach varStatus properties

Property Getter Description

• current getCurrent() The item (from the collection) for the current round of iteration.

• index getIndex() The zero-based index for the current round of iteration.

• count getCount() The one-based count for the current round of iteration

• first isFirst() Flag indicating whether the current round is the first pass through the iteration

• last isLast() Flag indicating whether the current round is the last pass through the iteration

• begin getBegin() The value of the begin attribute

• end getEnd() The value of the end attribute

• step getStep() The value of the step attribute

The problem you're having is that the event-handlers are being bound before the elements are present in the DOM, if you wrap the jQuery inside of a $(document).ready() then it should work perfectly well:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").show("slow");
        });

    });

An alternative is to place the <script></script> at the foot of the page, so it's encountered after the DOM has been loaded and ready.

To make the div hide again, once the #music element is clicked, simply use toggle():

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").toggle();
        });
    });

JS Fiddle demo.

And for fading:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").fadeToggle();
        });
    });

If "partly cherry picking" means "within files, choosing some changes but discarding others", it can be done by bringing in git stash:

1. Do the full cherry pick.
2. git reset HEAD^ to convert the entire cherry-picked commit into unstaged working changes.
3. Now git stash save --patch: interactively select unwanted material to stash.
4. Git rolls back the stashed changes from your working copy.
5. git commit
6. Throw away the stash of unwanted changes: git stash drop.

Tip: if you give the stash of unwanted changes a name: git stash save --patch junk then if you forget to do (6) now, later you will recognize the stash for what it is.

Following will disable all the input but will not able it to btn class and also added class to overwrite disable css.

$('#EditForm :input').not('.btn').attr("disabled", true).addClass('disabledClass');

css class

.disabledClass{
  background-color: rgb(235, 235, 228) !important;
}

best put brackets around foo, and use +=

list+=['foo']

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

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

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

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

In windows, the \n moves to the beginning of the next line. The \r moves to the beginning of the current line, without moving to the next line. I have used \r in my own console apps where I am testing out some code and I don't want to see text scrolling up my screen, so rather than use \n after printing out some text, of say, a frame rate (FPS), I will printf("%-10d\r", fps); This will return the cursor to the beginning of the line without moving down to the next line and allow me to have other information on the screen that doesn't get scrolled off while the framerate constantly updates on the same line (the %-10 makes certain the output is at least 10 characters, left justified so it ends up padded by spaces, overwriting any old values for that line). It's quite handy for stuff like this, usually when I have debugging stuff output to my console screen.

A little history

The /r stands for "return" or "carriage return" which owes it's history to the typewriter. A carriage return moved your carriage all the way to the right so you were typing at the start of the line.

The /n stands for "new line", again, from typewriter days you moved down to a new line. Not nessecarily to the start of it though, which is why some OSes adopted the need for both a /r return followed by a /n newline, as that was the order a typewriter did it in. It also explains the old 8bit computers that used to have "Return" rather than "Enter", from "carriage return", which was familiar.

The regex method is superior I think, but if you wanted to use the humble substring

string input= "my name is (Jayne C)";
int start = input.IndexOf("(");
int stop = input.IndexOf(")");
string output = input.Substring(start+1, stop - start - 1);

or

string input = "my name is (Jayne C)";
string output  = input.Substring(input.IndexOf("(") +1, input.IndexOf(")")- input.IndexOf("(")- 1);

How about this?

JSONObject jsonObject = new JSONObject           (YOUR_JSON_STRING);
JSONObject ipinfo     = jsonObject.getJSONObject ("ipinfo");
String     ip_address = ipinfo.getString         ("ip_address");
JSONObject location   = ipinfo.getJSONObject     ("Location");
String     latitude   = location.getString       ("latitude");
System.out.println (latitude);

This sample code using "org.json.JSONObject"

The easiest way is:

var oldstr="Angular isn't easy";
var newstr=oldstr.toString().replace("isn't","is");

use mb_substr function

    mb_substr("?abc", 1);

You can set the value property using client script after the element is created:

<input type="text" id="fee" />

<script type="text/javascript>
document.getElementById('fee').value = '1000';
</script>

Update Aug 2020

Although the below is still worth reading for the useful info, we have had Flexbox for some time now, so just use that, as per this answer.

You can't use:

vertical-align:middle because it's not applicable to block-level elements

margin-top:auto and margin-bottom:auto because their used values would compute as zero

margin-top:-50% because percentage-based margin values are calculated relative to the width of containing block

In fact, the nature of document flow and element height calculation algorithms make it impossible to use margins for centering an element vertically inside its parent. Whenever a vertical margin's value is changed, it will trigger a parent element height re-calculation (re-flow), which would in turn trigger a re-center of the original element... making it an infinite loop.

You can use:

A few workarounds like this which work for your scenario; the three elements have to be nested like so:

.container {
    display: table;
    height: 100%;
    position: absolute;
    overflow: hidden;
    width: 100%;
}
.helper {
    #position: absolute;
    #top: 50%;
    display: table-cell;
    vertical-align: middle;
}
.content {
    #position: relative;
    #top: -50%;
    margin: 0 auto;
    width: 200px;
    border: 1px solid orange;
}

<div class="container">
    <div class="helper">
        <div class="content">
            <p>stuff</p>
        </div>
    </div>
</div

JSFiddle works fine according to Browsershot.

Well, since nobody else has stepped up, I'll write the easy code to do this:

x = ms / 1000
seconds = x % 60
x /= 60
minutes = x % 60
x /= 60
hours = x % 24
x /= 24
days = x

I'm just glad you stopped at days and didn't ask for months. :)

Note that in the above, it is assumed that / represents truncating integer division. If you use this code in a language where / represents floating point division, you will need to manually truncate the results of the division as needed.

This seemed to have worked for me!

Mat a_image = imread(argv[1]);

cvtColor(a_image, a_image, CV_BGR2GRAY);
GaussianBlur(a_image, a_image, Size(7,7), 1.5, 1.5);
threshold(a_image, a_image, 100, 255, CV_THRESH_BINARY);

If it is a maven project

1. right click on the pom.xml
2. Add As Maven Project

Thanks

Is there and image in the list view that you are using> then follow the link: http://vikaskanani.wordpress.com/2011/07/20/android-custom-image-gallery-with-checkbox-in-grid-to-select-multiple/

I think when you work out on the link that I have provided first every thing will work fine, I have tried that. If you want a refined answer please elaborate the question with code and description.

Just making code shorter you can use ES6 features. The same things can be written as

app.get("/recipes", (req, res) => {
    res.render("recipes.ejs", {
        recipes
    });
}); 

And the Templeate can be render as the same!

<%if (recipes.length > 0) { %>
// Do something with more than 1 recipe
<% } %>

You can call the indexer directly on the datatable variable as well:

var cellValue = dt[i].ColumnName

Public Function TestError() As String()
     Return {"foo", "bar"}
End Function

Works fine for me and should work for you, but you may need allow using implicit declarations in your project. I believe this is turning off Options strict in the Compile section of the program settings.

Since you are using VS 2008 (VB.NET 9.0) you have to declare create the new instance

New String() {"foo", "Bar"}

The HttpServletRequest object provides a map of parameters already. See request.getParameterMap() for more details.

async is now an independent module : grequests.

See here : https://github.com/kennethreitz/grequests

And there: Ideal method for sending multiple HTTP requests over Python?

installation:

$ pip install grequests

usage:

build a stack:

import grequests

urls = [
    'http://www.heroku.com',
    'http://tablib.org',
    'http://httpbin.org',
    'http://python-requests.org',
    'http://kennethreitz.com'
]

rs = (grequests.get(u) for u in urls)

send the stack

grequests.map(rs)

result looks like

[<Response [200]>, <Response [200]>, <Response [200]>, <Response [200]>, <Response [200]>]

grequests don't seem to set a limitation for concurrent requests, ie when multiple requests are sent to the same server.

That's probably a requireJS module definition

Check here for more details

RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code.

I know it's a bit late, but I just came across this post and wanted to mention that I don't really see way everybody wants to do it in a difficult way... The problem here is just that the book class takes twoside as default, so, as gromgull said, just pass oneside as argument and it's solved.

You need to use HAVING, not WHERE.

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

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

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

Here are some more tests

True if string is not empty:

[ -n "$var" ]
[[ -n $var ]]
test -n "$var"
[ "$var" ]
[[ $var ]]
(( ${#var} ))
let ${#var}
test "$var"

True if string is empty:

[ -z "$var" ]
[[ -z $var ]]
test -z "$var"
! [ "$var" ]
! [[ $var ]]
! (( ${#var} ))
! let ${#var}
! test "$var"

There is an alternative way of just killing the daemon process by calling

kill -TERM PID

where PID is the value stored in the file mysqld.pid or the mysqld process id which can be obtained by issuing the command ps -a | grep mysqld.

Add div wrapper

<div id=myForm>
<select name=countries>
 <option value=af>Afghanistan</option>
 <option value=ax>Åland Islands</option>
 ...
 <option value=gs>South Georgia and the South Sandwich Islands</option>
 ...
</select>
</div>

and then write CSS

#myForm select { 
width:200px; }

#myForm select:focus {
width:auto; }

Hope this will help.

Here is a way to have some flexibility in what should be discarded and what should be replaced. This is how I currently do it.

This might not work as the boxing and autoboxing from Integer to int and viceversa is dependant on JVM and there is high possibility that two different numbers might get hashed to same address if they are between -128 and 127.

Some people seem to be confusing these macros with assert().

These macros implement a compile-time test, while assert() is a runtime test.

The use-case for CORS is simple. Imagine the site alice.com has some data that the site bob.com wants to access. This type of request traditionally wouldn’t be allowed under the browser’s same origin policy. However, by supporting CORS requests, alice.com can add a few special response headers that allows bob.com to access the data. In order to understand it well, please visit this nice tutorial.. How to solve the issue of CORS

A static variable declared in a header file outside of the class would be file-scoped in every .c file which includes the header. That means separate copy of a variable with same name is accessible in each of the .c files where you include the header file.

A static class variable on the other hand is class-scoped and the same static variable is available to every compilation unit that includes the header containing the class with static variable.

try this:

<a id="send-thoughts" href="">Click</a>
<textarea id="message"></textarea>
<!--<textarea id="#message"></textarea>-->

            jQuery("a#send-thoughts").click(function() {
                //var thought = jQuery("textarea#message").val();
                var thought = $("#message").val();
                alert(thought);
            });

Check the IIS settings. I use IIS 7.5 with 32 or 64 bit compilation within the .NET framework. If you have an app that uses 32-bit mode, make sure to enable the App Pool to be able to use 32-bit instruction. Otherwise, nothing seems to work no matter how much you set the security or strong sign the DLL.

Either

• HSQLDB - Used by OpenOffice, tested and stable. It's easy to use. If you want to edit your db-data, you can just open the file and edit the insert statements.

or

• H2 - Said to be faster (by the developer, who originally designed hsqldb, too)

Which one you use is up to you, depending how much performance and how much stability you need.

The developer of H2 has put up a nice performance evaluation:
http://www.h2database.com/html/performance.html

You can specialize your templates based on what's passed into their parameters like this:

template <> void foo<animal> {

}

Note that this creates an entirely new function based on the type that's passed as T. This is usually preferable as it reduces clutter and is essentially the reason we have templates in the first place.

Here is complete Twitter bootstrap example and applied active class based on query string.

Few steps to follow to achieve correct solution:

1) Include latest jquery.js and bootstrap.js javascript file.

2) Include latest bootstrap.css file

3) Include querystring-0.9.0.js for getting query string variable value in js.

4) HTML:

<div class="navbar">
  <div class="navbar-inner">
    <div class="container">
      <ul class="nav">
        <li class="active">
          <a href="#?page=0">

Gilean's answer is great, but I just wanted to add that sometimes there are rare exceptions to best practices, and you might want to test your environment both ways to see what will work best.

In one case, I found that query worked faster for my purposes because I was bulk transferring trusted data from an Ubuntu Linux box running PHP7 with the poorly supported Microsoft ODBC driver for MS SQL Server.

I arrived at this question because I had a long running script for an ETL that I was trying to squeeze for speed. It seemed intuitive to me that query could be faster than prepare & execute because it was calling only one function instead of two. The parameter binding operation provides excellent protection, but it might be expensive and possibly avoided if unnecessary.

Given a couple rare conditions:

1. If you can't reuse a prepared statement because it's not supported by the Microsoft ODBC driver.

2. If you're not worried about sanitizing input and simple escaping is acceptable. This may be the case because binding certain datatypes isn't supported by the Microsoft ODBC driver.

3. PDO::lastInsertId is not supported by the Microsoft ODBC driver.

Here's a method I used to test my environment, and hopefully you can replicate it or something better in yours:

To start, I've created a basic table in Microsoft SQL Server

CREATE TABLE performancetest (
    sid INT IDENTITY PRIMARY KEY,
    id INT,
    val VARCHAR(100)
);

And now a basic timed test for performance metrics.

$logs = [];

$test = function (String $type, Int $count = 3000) use ($pdo, &$logs) {
    $start = microtime(true);
    $i = 0;
    while ($i < $count) {
        $sql = "INSERT INTO performancetest (id, val) OUTPUT INSERTED.sid VALUES ($i,'value $i')";
        if ($type === 'query') {
            $smt = $pdo->query($sql);
        } else {
            $smt = $pdo->prepare($sql);
            $smt ->execute();
        }
        $sid = $smt->fetch(PDO::FETCH_ASSOC)['sid'];
        $i++;
    }
    $total = (microtime(true) - $start);
    $logs[$type] []= $total;
    echo "$total $type\n";
};

$trials = 15;
$i = 0;
while ($i < $trials) {
    if (random_int(0,1) === 0) {
        $test('query');
    } else {
        $test('prepare');
    }
    $i++;
}

foreach ($logs as $type => $log) {
    $total = 0;
    foreach ($log as $record) {
        $total += $record;
    }
    $count = count($log);
    echo "($count) $type Average: ".$total/$count.PHP_EOL;
}

I've played with multiple different trial and counts in my specific environment, and consistently get between 20-30% faster results with query than prepare/execute

5.8128969669342 prepare
5.8688418865204 prepare
4.2948560714722 query
4.9533629417419 query
5.9051351547241 prepare
4.332102060318 query
5.9672858715057 prepare
5.0667371749878 query
3.8260300159454 query
4.0791549682617 query
4.3775160312653 query
3.6910600662231 query
5.2708210945129 prepare
6.2671611309052 prepare
7.3791449069977 prepare
(7) prepare Average: 6.0673267160143
(8) query Average: 4.3276024162769

I'm curious to see how this test compares in other environments, like MySQL.

I think you've created your project like this:

vue init webpack myproject

Well, now you can run

npm run build

Copy index.html and /dist/ folder into your website root directory. Done.

I also got this error, but for a .h file. The fix was to go into the file Properties (via Solution Explorer's file popup menu) and set the file type correctly. It was set to C/C++ Compiler instead of the correct C/C++ header.

In Lumen's .env file, specify the timezones. For India, it would be like:

APP_TIMEZONE = 'Asia/Calcutta'
DB_TIMEZONE = '+05:30'

BackgroundTint works as color filter.

FEFBDE as tint

37AEE4 as background

Try seeing the difference by comment tint/background and check the output when both are set.

I got this solution for truncating leading zeros(number or any string) in javascript:

<script language="JavaScript" type="text/javascript">
<!--
function trimNumber(s) {
  while (s.substr(0,1) == '0' && s.length>1) { s = s.substr(1,9999); }
  return s;
}

var s1 = '00123';
var s2 = '000assa';
var s3 = 'assa34300';
var s4 = 'ssa';
var s5 = '121212000';

alert(s1 + '=' + trimNumber(s1));
alert(s2 + '=' + trimNumber(s2));
alert(s3 + '=' + trimNumber(s3));
alert(s4 + '=' + trimNumber(s4));
alert(s5 + '=' + trimNumber(s5));
// end hiding contents -->
</script>

I was having this problem on a Windows 7 (64 bit) after a power outage. The SQLEXPRESS service was not started even though is status was set to 'Automatic' and the mahine had been rebooted several times. Had to start the service manually.

interface IDefaultLayoutProps {
    children: React.ReactNode
}

const DefaultLayout: React.SFC<IDefaultLayoutProps> = ({children}) => {
    return (
        <div className="DefaultLayout">
            {children}
        </div>
    );
}


const LayoutRoute: React.SFC<IDefaultLayoutRouteProps & RouteProps> = ({component: Component, layout: Layout, ...rest}) => {
const handleRender = (matchProps: RouteComponentProps<{}, StaticContext>) => (
        <Layout>
            <Component {...matchProps} />
        </Layout>
    );

    return (
        <Route {...rest} render={handleRender}/>
    );
}

const ScreenRouter = () => (
    <BrowserRouter>
        <div>
            <Link to="/">Home</Link>
            <Link to="/counter">Counter</Link>
            <Switch>
                <LayoutRoute path="/" exact={true} layout={DefaultLayout} component={HomeScreen} />
                <LayoutRoute path="/counter" layout={DashboardLayout} component={CounterScreen} />
            </Switch>
        </div>
    </BrowserRouter>
);

This is not a generic answer.

However: Some programs, especially services and long-running programs, create (or offer to create, optionally) a "pid file".

For instance, LibreOffice offers --pidfile={file}, see the docs.

I was looking for quite some time for a Java/Linux solution but the PID was (in my case) lying at hand.

it's should overlap, so it turned off. Try to open in your text editor and find display_errors and turn it on. It works for me

Besides formatting, puts returns a nonnegative integer if successful or EOF if unsuccessful; while printf returns the number of characters printed (not including the trailing null).

Similar to @ernest-a's answer but without affecting $OLDPWD or define a new function you could fire a subshell (cd <path>; pwd)

$ pwd
/etc/apache2
$ cd ../cups 
$ cd -
/etc/apache2
$ (cd ~/..; pwd)
/Users
$ cd -
/etc/cups

new Long(Integer.longValue());

or

new Long(Integer.toString());

The ls utility should conform to IEEE Std 1003.1-2001 (POSIX.1) which states:

22027: it shall sort directory and non-directory operands separately according to the collating sequence in the current locale.

26027: By default, the format is unspecified, but the output shall be sorted alphabetically by symbol name:

• Library or object name, if -A is specified
• Symbol name
• Symbol type
• Value of the symbol
• The size associated with the symbol, if applicable

The simplest way seems to be :

@Around("execution(@MyHandling * com.exemple.YourService.*(..))")
public Object aroundServiceMethodAdvice(final ProceedingJoinPoint pjp)
   throws Throwable {
   // perform actions before

   return pjp.proceed();

   // perform actions after
}

It will intercept execution of all methods specifically annotated with '@MyHandling' in 'YourService' class. To intercept all methods without exception, just put the annotation directly on the class.

No matter of the private / public scope here, but keep in mind that spring-aop cannot use aspect for method calls in same instance (typically private ones), because it doesn't use the proxy class in this case.

We use @Around advice here, but it's basically the same syntax with @Before, @After or any advice.

By the way, @MyHandling annotation must be configured like this :

@Retention(RetentionPolicy.RUNTIME)
@Target( { ElementType.METHOD, ElementType.TYPE })
public @interface MyHandling {

}

A non-lodash way to solve this in a fairly readable and efficient manner:

function filterByKeys(obj, keys = []) {_x000D_
  const filtered = {}_x000D_
  keys.forEach(key => {_x000D_
    if (obj.hasOwnProperty(key)) {_x000D_
      filtered[key] = obj[key]_x000D_
    }_x000D_
  })_x000D_
  return filtered_x000D_
}_x000D_
_x000D_
const myObject = {_x000D_
  a: 1,_x000D_
  b: 'bananas',_x000D_
  d: null_x000D_
}_x000D_
_x000D_
const result = filterByKeys(myObject, ['a', 'd', 'e']) // {a: 1, d: null}_x000D_
console.log(result)

I needed to snapshot a div on the page (for a webapp I wrote) that is protected by JWT's and makes very heavy use of Angular.

I had no luck with any of the above methods.

I ended up taking the outerHTML of the div I needed, cleaning it up a little (*) and then sending it to the server where I run wkhtmltopdf against it.

This is working very well for me.

(*) various input devices in my pages didn't render as checked or have their text values when viewed in the pdf... So I run a little bit of jQuery on the html before I send it up for rendering. ex: for text input items -- I copy their .val()'s into 'value' attributes, which then can be seen by wkhtmlpdf

One more method (bulletproof) taken from here utilizing 'display:table' rule:

Markup

<div class="container">
  <div class="outer">
    <div class="inner">
      <div class="centered">
        ...
      </div>
    </div>
  </div>
</div>

CSS:

.outer {
  display: table;
  width: 100%;
  height: 100%;
}
.inner {
  display: table-cell;
  vertical-align: middle;
  text-align: center;
}
.centered {
  position: relative;
  display: inline-block;

  width: 50%;
  padding: 1em;
  background: orange;
  color: white;
}

Perfect answer for your question can be found on MYSQL site itself.refer their manual(without using PHP)

http://forums.mysql.com/read.php?20,17671,27914

According to them use LONGBLOB datatype. with that you can only store images less than 1MB only by default,although it can be changed by editing server config file.i would also recommend using MySQL workBench for ease of database management

actually, your code is not working because when you write:

$.post("someurl.php",someData,doSomething(data, myDiv),"json"); 

you place a function call as the third parameter rather than a function reference.

Well, depending on your needs you can choose any of the following. Out put is written against each method

You can choose the one you need

This will round

decimal d = 2.5789m;
Console.WriteLine(d.ToString("#.##")); // 2.58

This will ensure that 2 decimal places are written.

d = 2.5m;
Console.WriteLine(d.ToString("F")); //2.50

if you want to write commas you can use this

d=23545789.5432m;
Console.WriteLine(d.ToString("n2")); //23,545,789.54

if you want to return the rounded of decimal value you can do this

d = 2.578m;
d = decimal.Round(d, 2, MidpointRounding.AwayFromZero); //2.58

For those who don't care about IE6/IE7, the same guy who wrote Raphael built an svg engine specifically for modern browsers: Snap.svg .. they have a really nice site with good docs: http://snapsvg.io

snap.svg couldn't be easier to use right out of the box and can manipulate/update existing SVGs or generate new ones. You can read this stuff on the snap.io about page but here's a quick run down:

Cons

• To make use of snap's features you must forgo on support for older browsers. Raphael supports browsers like IE6/IE7, snap features are only supported by IE9 and up, Safari, Chrome, Firefox, and Opera.

Pros

• Implements the full features of SVG like masking, clipping, patterns, full gradients, groups, and more.

• Ability to work with existing SVGs: content does not have to be generated with Snap for it to work with Snap, allowing you to create the content with any common design tools.

• Full animation support using a straightforward, easy-to-implement JavaScript API

• Works with strings of SVGs (for example, SVG files loaded via Ajax) without having to actually render them first, similar to a resource container or sprite sheet.

You're opening a file, then passing the file pointer to a function that only wants a file name to open the file itself. You can simplify your call to;

void main(void)
{
  printf("LINES: %d\n",countlines("Test.txt"));
}

EDIT: You're changing the question around so it's very hard to answer; at first you got your change to main() wrong, you forgot that the first parameter is argc, so it crashed. Now you have the problem of;

if (fp == NULL);   // <-- note the extra semicolon that is the only thing 
                   //     that runs conditionally on the if 
  return 0;        // Always runs and returns 0

which will always return 0. Remove that extra semicolon, and you should get a reasonable count.

I used a relative path in the xsi:noNamespaceSchemaLocation to provide the local xsd file (because I could not use a namespace in the instance xml).

<?xml version="1.0" encoding="UTF-8"?>
<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="../project/schema.xsd">
</root>

Validation works and the warning is fixed (not ignored).

I had a similar problem and it was the version of bootstrap.js included in my visual studio project. I linked to here and it worked great

 <script src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>

When you decorate a model property with [DataType(DataType.Date)] the default template in ASP.NET MVC 4 generates an input field of type="date":

<input class="text-box single-line" 
       data-val="true" 
       data-val-date="The field EstPurchaseDate must be a date."
       id="EstPurchaseDate" 
       name="EstPurchaseDate" 
       type="date" value="9/28/2012" />

Browsers that support HTML5 such Google Chrome render this input field with a date picker.

In order to correctly display the date, the value must be formatted as 2012-09-28. Quote from the specification:

value: A valid full-date as defined in [RFC 3339], with the additional qualification that the year component is four or more digits representing a number greater than 0.

You could enforce this format using the DisplayFormat attribute:

[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public Nullable<System.DateTime> EstPurchaseDate { get; set; }

All CheckBox Checked

$("input[type=checkbox]").prop('checked', true);

This would be easier to do with flexbox. Using flexbox will let you not to specify the height of your content and can adjust automatically on the height it contains.

DEMO

here's the gist of the demo

.container{

  display: flex;
  height: 100%;
  justify-content: center;
  align-items: center;

}

html

<div class="container">
  <div class='content'> //you can size this anyway you want
    put anything you want here,
  </div>

I have a slightly different approach that might be useful/more beneficial to some.

Under your main project folder, create a resource folder. Your folder structure should look something like this.

• Project Folder
  • build
  • dist
  • lib
  • nbproject
  • resources
  • src

Go to the properties of your project. You can do this by right clicking on your project in the Projects tab window and selecting Properties in the drop down menu.

Under categories on the left side, select Sources.

In Source Package Folders on the right side, add your resource folder using the Add Folder button. Once you click OK, you should see a Resources folder under your project.

You should now be able to pull resources using this line or similar approach:

MyClass.class.getResource("/main.jpg");

If you were to create a package called Images under the resources folder, you can retrieve the resource like this:

MyClass.class.getResource("/Images/main.jpg");

You can also use the sc tool to set it.

You can also call it from PowerShell and add additional checks if needed. The advantage of this tool vs. PowerShell is that the sc tool can also set the start type to auto delayed.

# Get Service status
$Service = "Wecsvc"
sc.exe qc $Service

# Set Service status
$Service = "Wecsvc"
sc.exe config $Service start= delayed-auto

In addition to S.Lott's answer and as becomingGuru mentioned in comments, its possible to add the queryset filters by overriding the ModelForm.__init__ function. (This could easily apply to regular forms) it can help with reuse and keeps the view function tidy.

class ClientForm(forms.ModelForm):
    def __init__(self,company,*args,**kwargs):
        super (ClientForm,self ).__init__(*args,**kwargs) # populates the post
        self.fields['rate'].queryset = Rate.objects.filter(company=company)
        self.fields['client'].queryset = Client.objects.filter(company=company)

    class Meta:
        model = Client

def addclient(request, company_id):
        the_company = get_object_or_404(Company, id=company_id)

        if request.POST:
            form = ClientForm(the_company,request.POST)  #<-- Note the extra arg
            if form.is_valid():
                form.save()
                return HttpResponseRedirect(the_company.get_clients_url())
        else:
            form = ClientForm(the_company)

        return render_to_response('addclient.html', 
                                  {'form': form, 'the_company':the_company})

This can be useful for reuse say if you have common filters needed on many models (normally I declare an abstract Form class). E.g.

class UberClientForm(ClientForm):
    class Meta:
        model = UberClient

def view(request):
    ...
    form = UberClientForm(company)
    ...

#or even extend the existing custom init
class PITAClient(ClientForm):
    def __init__(company, *args, **args):
        super (PITAClient,self ).__init__(company,*args,**kwargs)
        self.fields['support_staff'].queryset = User.objects.exclude(user='michael')

Other than that I'm just restating Django blog material of which there are many good ones out there.

Global exclusions look like they're being worked on, but until then...

From the Sonatype maven reference (bottom of the page):

Dependency management in a top-level POM is different from just defining a dependency on a widely shared parent POM. For starters, all dependencies are inherited. If mysql-connector-java were listed as a dependency of the top-level parent project, every single project in the hierarchy would have a reference to this dependency. Instead of adding in unnecessary dependencies, using dependencyManagement allows you to consolidate and centralize the management of dependency versions without adding dependencies which are inherited by all children. In other words, the dependencyManagement element is equivalent to an environment variable which allows you to declare a dependency anywhere below a project without specifying a version number.

As an example:

  <dependencies>
    <dependency>
      <groupId>commons-httpclient</groupId>
      <artifactId>commons-httpclient</artifactId>
      <version>3.1</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-beans</artifactId>
      <version>3.0.5.RELEASE</version>
    </dependency>
  </dependencies>
  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-beans</artifactId>
        <exclusions>
          <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
          </exclusion>
        </exclusions>
      </dependency>
      <dependency>
        <groupId>commons-httpclient</groupId>
        <artifactId>commons-httpclient</artifactId>
        <exclusions>
          <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
          </exclusion>
        </exclusions>
      </dependency>
    </dependencies>
  </dependencyManagement>

It doesn't make the code less verbose overall, but it does make it less verbose where it counts. If you still want it less verbose you can follow these tips also from the Sonatype reference.

IF YOU ARE NOT IN PRODUCTION, you can look in your flywayTable in the data base and remove the line which contain the name of the script which has been applied.

flywayTable is a project option which define the name of the table in the db used by flyway which contain information about the version of this db, already applied scripts...

RSS is the Resident Set Size and is used to show how much memory is allocated to that process and is in RAM. It does not include memory that is swapped out. It does include memory from shared libraries as long as the pages from those libraries are actually in memory. It does include all stack and heap memory.

VSZ is the Virtual Memory Size. It includes all memory that the process can access, including memory that is swapped out, memory that is allocated, but not used, and memory that is from shared libraries.

So if process A has a 500K binary and is linked to 2500K of shared libraries, has 200K of stack/heap allocations of which 100K is actually in memory (rest is swapped or unused), and it has only actually loaded 1000K of the shared libraries and 400K of its own binary then:

RSS: 400K + 1000K + 100K = 1500K
VSZ: 500K + 2500K + 200K = 3200K

Since part of the memory is shared, many processes may use it, so if you add up all of the RSS values you can easily end up with more space than your system has.

The memory that is allocated also may not be in RSS until it is actually used by the program. So if your program allocated a bunch of memory up front, then uses it over time, you could see RSS going up and VSZ staying the same.

There is also PSS (proportional set size). This is a newer measure which tracks the shared memory as a proportion used by the current process. So if there were two processes using the same shared library from before:

PSS: 400K + (1000K/2) + 100K = 400K + 500K + 100K = 1000K

Threads all share the same address space, so the RSS, VSZ and PSS for each thread is identical to all of the other threads in the process. Use ps or top to view this information in linux/unix.

There is way more to it than this, to learn more check the following references:

Assuming that it's a TCP (rather than UDP) port that you're trying to use:

1. On the server itself, use netstat -an to check to see which ports are listening.

2. From outside, just use telnet host port (or telnet host:port on Unix systems) to see if the connection is refused, accepted, or timeouts.

On that latter test, then in general:

• connection refused means that nothing is running on that port
• accepted means that something is running on that port
• timeout means that a firewall is blocking access

On Windows 7 or Windows Vista the default option 'telnet' is not recognized as an internal or external command, operable program or batch file. To solve this, just enable it: Click *Start** → Control Panel → Programs → Turn Windows Features on or off. In the list, scroll down and select Telnet Client and click OK.

That meta tag basically specifies which character set a website is written with.

Here is a definition of UTF-8:

UTF-8 (U from Universal Character Set + Transformation Format—8-bit) is a character encoding capable of encoding all possible characters (called code points) in Unicode. The encoding is variable-length and uses 8-bit code units.

OUTDATED: Many modern browsers now have first-class support for crypto operations. See Vitaly Zdanevich's answer below.

The Stanford JS Crypto Library contains an implementation of SHA-256. While crypto in JS isn't really as well-vetted an endeavor as other implementation platforms, this one is at least partially developed by, and to a certain extent sponsored by, Dan Boneh, who is a well-established and trusted name in cryptography, and means that the project has some oversight by someone who actually knows what he's doing. The project is also supported by the NSF.

It's worth pointing out, however...
... that if you hash the password client-side before submitting it, then the hash is the password, and the original password becomes irrelevant. An attacker needs only to intercept the hash in order to impersonate the user, and if that hash is stored unmodified on the server, then the server is storing the true password (the hash) in plain-text.

So your security is now worse because you decided add your own improvements to what was previously a trusted scheme.

The theoretical limit is O(n) because you need to touch each sock (unless some are already paired somehow).

You can achieve O(n) with radix sort. You just need to pick some attributes for the buckets.

1. First you can choose (hers, mine) - split them into 2 piles,
2. then use colors (can have any order for the colors, e.g. alphabetically by color name) - split them into piles by color (remember to keep the initial order from step 1 for all socks in the same pile),
3. then length of the sock,
4. then texture, ....

If you can pick a limited number of attributes, but enough attributes that can uniquely identify each pair, you should be done in O(k * n), which is O(n) if we can consider k is limited.

void myFunc(char* str, char c)
{
    char* ptr;
    int index;

    ptr = strchr(str, c);
    if (ptr == NULL)
    {
        printf("Character not found\n");
        return;
    }

    index = ptr - str;

    printf("The index is %d\n", index);
    ASSERT(str[index] == c);  // Verify that the character at index is the one we want.
}

This code is currently untested, but it demonstrates the proper concept.

I think it depends on how you installed python. Note that you can have multiple installs of python, I do on my machine. However, if you install via an msi of a version of python 2.2 or above, I believe it creates a registry key like so:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Python.exe

which gives this value on my machine:

C:\Python25\Python.exe

You just read the registry key to get the location.

However, you can install python via an xcopy like model that you can have in an arbitrary place, and you just have to know where it is installed.

you can try this

pip install opencv==2.4.9

from the pandas doc http://pandas.pydata.org/pandas-docs/stable/dsintro.html Series is a one-dimensional labeled array capable of holding any data type. To read data in form of panda Series:

import pandas as pd
ds = pd.Series(data, index=index)

DataFrame is a 2-dimensional labeled data structure with columns of potentially different types.

import pandas as pd
df = pd.DataFrame(data, index=index)

In both of the above index is list

for example: I have a csv file with following data:

,country,popuplation,area,capital
BR,Brazil,10210,12015,Brasile
RU,Russia,1025,457,Moscow
IN,India,10458,457787,New Delhi

To read above data as series and data frame:

import pandas as pd
file_data = pd.read_csv("file_path", index_col=0)
d = pd.Series(file_data.country, index=['BR','RU','IN'] or index =  file_data.index)

output:

>>> d
BR           Brazil
RU           Russia
IN            India

df = pd.DataFrame(file_data.area, index=['BR','RU','IN'] or index = file_data.index )

output:

>>> df
      area
BR   12015
RU     457
IN  457787

This works fine for me:

while True:
   answer = input('Do you want to continue?:')
   if answer.lower().startswith("y"):
      print("ok, carry on then")
   elif answer.lower().startswith("n"):
      print("sayonara, Robocop")
      exit()

edit: use input in python 3.2 instead of raw_input

In my project I usually use an external function that "filters" data retrieved with mysql_fetch_assoc.

You can rename fields in your table so that is intuitive to understand which data type is stored.

For example, you can add a special suffix to each numeric field: if userid is an INT(11) you can rename it userid_i or if it is an UNSIGNED INT(11) you can rename userid_u. At this point, you can write a simple PHP function that receive as input the associative array (retrieved with mysql_fetch_assoc), and apply casting to the "value" stored with those special "keys".

In case you're like me and have an application using NHibernate and the above answers have not resolved your issue.

You should look at the connection string in your application; possibly in the webconfig file to ensure it is correct.

Although this question is pretty old and it has already a-lot answers, I think it is worth to provide an alternative. Using native java classes makes it very verbose to just use pem files and almost forces you wanting to convert the pem files into p12 or jks files as using p12 or jks files are much easier. I want to give anyone who wants an alternative for the already provided answers.

var keyManager = PemUtils.loadIdentityMaterial("certificate-chain.pem", "private-key.pem");

I need to provide some disclaimer here, I am the library maintainer

A fun, but useless way to do this:

az  = ('a'..'z').to_a
azz = az.map{|e| [e, az.index(e)+2]}

Per Mozilla's Map documentation, you can initialize as follows:

private _gridOptions:Map<string, Array<string>> = 
    new Map([
        ["1", ["test"]],
        ["2", ["test2"]]
    ]);

I know that I am late to party but performed test before actually implement the solution.

I did perform test against inbuilt MD5 class and also md5sum.exe. In my case inbuilt class took 13 second where md5sum.exe too around 16-18 seconds in every run.

    DateTime current = DateTime.Now;
    string file = @"C:\text.iso";//It's 2.5 Gb file
    string output;
    using (var md5 = MD5.Create())
    {
        using (var stream = File.OpenRead(file))
        {
            byte[] checksum = md5.ComputeHash(stream);
            output = BitConverter.ToString(checksum).Replace("-", String.Empty).ToLower();
            Console.WriteLine("Total seconds : " + (DateTime.Now - current).TotalSeconds.ToString() + " " + output);

I considered giving a comment under the answer by taggon to this very question, but well, i felt it owed more explanation for those interested in details.

Uncaught TypeError: Cannot read property 'value' of undefined is strictly a JavaScript error.
(Note that value can be anything, but for this question value is 'map')

It's critical to understand that point, just so you avoid endless debugging cycles.
This error is common especially if just starting out in JavaScript (and it's libraries/frameworks).
For React, this has a lot to do with understanding the component lifecycle methods.

// Follow this example to get the context
// Ignore any complexity, focus on how 'props' are passed down to children

import React, { useEffect } from 'react'

// Main component
const ShowList = () => {
  // Similar to componentDidMount and componentDidUpdate
  useEffect(() => {// dispatch call to fetch items, populate the redux-store})

  return <div><MyItems items={movies} /></div>
}

// other component
const MyItems = props =>
  <ul>
    {props.items.map((item, i) => <li key={i}>item</li>)}
  </ul>


/**
  The above code should work fine, except for one problem.
  When compiling <ShowList/>,
  React-DOM renders <MyItems> before useEffect (or componentDid...) is called.
  And since `items={movies}`, 'props.items' is 'undefined' at that point.
  Thus the error message 'Cannot read property map of undefined'
 */

As a way to tackle this problem, @taggon gave a solution (see first anwser or link).

Solution: Set an initial/default value.
In our example, we can avoid items being 'undefined' by declaring a default value of an empty array.

Why? This allows React-DOM to render an empty list initially.
And when the useEffect or componentDid... method is executed, the component is re-rendered with a populated list of items.

// Let's update our 'other' component
// destructure the `items` and initialize it as an array

const MyItems = ({items = []}) =>
  <ul>
    {items.map((item, i) => <li key={i}>item</li>)}
  </ul>

This one line answer comes from someone related Ask Ubuntu Q&A:

[ "${FLOCKER}" != "$0" ] && exec env FLOCKER="$0" flock -en "$0" "$0" "$@" || :
#     This is useful boilerplate code for shell scripts.  Put it at the top  of
#     the  shell script you want to lock and it'll automatically lock itself on
#     the first run.  If the env var $FLOCKER is not set to  the  shell  script
#     that  is being run, then execute flock and grab an exclusive non-blocking
#     lock (using the script itself as the lock file) before re-execing  itself
#     with  the right arguments.  It also sets the FLOCKER env var to the right
#     value so it doesn't run again.

Posting this late just for others..I bet the first coder is done by now. For simple datatypes no copy is needed, just revert to good old C code methods.

std::vector <int>   myVec;
int *p;
// Add some data here and set start, then
p=myVec.data()+start;

Then pass the pointer p and a len to anything needing a subvector.

notelen must be!! len < myVec.size()-start

You were just missing the second half of the column statement telling it to remove the entire column, since most normal Ranges start with a Column Letter, it was looking for a number and didn't get one. The ":" gets the whole column, or row.

I think what you were looking for in your Range was this:

Range("C:C,F:F,I:I,L:L,O:O,R:R").Delete

Just change the column letters to match your needs.

Using vmin and vmax forces the range for the colors. Here's an example:

import matplotlib as m
import matplotlib.pyplot as plt
import numpy as np

cdict = {
  'red'  :  ( (0.0, 0.25, .25), (0.02, .59, .59), (1., 1., 1.)),
  'green':  ( (0.0, 0.0, 0.0), (0.02, .45, .45), (1., .97, .97)),
  'blue' :  ( (0.0, 1.0, 1.0), (0.02, .75, .75), (1., 0.45, 0.45))
}

cm = m.colors.LinearSegmentedColormap('my_colormap', cdict, 1024)

x = np.arange(0, 10, .1)
y = np.arange(0, 10, .1)
X, Y = np.meshgrid(x,y)

data = 2*( np.sin(X) + np.sin(3*Y) )

def do_plot(n, f, title):
    #plt.clf()
    plt.subplot(1, 3, n)
    plt.pcolor(X, Y, f(data), cmap=cm, vmin=-4, vmax=4)
    plt.title(title)
    plt.colorbar()

plt.figure()
do_plot(1, lambda x:x, "all")
do_plot(2, lambda x:np.clip(x, -4, 0), "<0")
do_plot(3, lambda x:np.clip(x, 0, 4), ">0")
plt.show()

Update for 2019, if you want to create a folder with path bucket_name/folder1/folder2 you can use this code:

from boto3 import client, resource

class S3Helper:

  def __init__(self):
      self.client = client("s3")
      self.s3 = resource('s3')

  def create_folder(self, path):
      path_arr = path.rstrip("/").split("/")
      if len(path_arr) == 1:
          return self.client.create_bucket(Bucket=path_arr[0])
      parent = path_arr[0]
      bucket = self.s3.Bucket(parent)
      status = bucket.put_object(Key="/".join(path_arr[1:]) + "/")
      return status

s3 = S3Helper()
s3.create_folder("bucket_name/folder1/folder2)

I just faced the mysql user password problem - ERROR 1045: Access denied for user: 'root@localhost' (Using password: NO) - when I tried to do a do-release-upgrade on my operational system. So I corrected it in 2 steps.

Firstly, as I did not had access on phpmyadmin, so I followed the "Recover MySQL root password" step on the tutorial mensioned by ThoKra: https://www.howtoforge.com/setting-changing-resetting-mysql-root-passwords

Secondly, with one of the users that I know the password, I made some password changes to the others users through phpmyadmin itself according to SonDang's information.

You need to escape the backslash \:

println yourString.replace("\\", "/")

No -- AL is the 8 least significant bits of AX. AX is the 16 least significant bits of EAX.

Perhaps it's easiest to deal with if we start with 04030201h in eax. In this case, AX will contain 0201h, AH wil contain 02h and AL will contain 01h.

The answers above are good, but insufficient if you have more than 1 project (.csproj) in the same folder.

First, you easily add the "PackageReference" tag to the .csproj file (either manually, by using the nuget package manager or by using the dotnet add package command).

But then, you need to run the "restore" command manually so you can tell it which project you are trying to restore (if I just clicked the restore button that popped up, nothing happened). You can do that by running:

dotnet restore Project-File-Name.csproj

And that installs the package

Another solution could be via pandas Series:

import pandas as pd

a = pd.Series([-2, 1, 5, 3, 8, 5, 6])
b = [1, 2, 5]
c = a[b]

You can then convert c back to a list if you want:

c = list(c)

The destructor of A will run when its lifetime is over. If you want its memory to be freed and the destructor run, you have to delete it if it was allocated on the heap. If it was allocated on the stack this happens automatically (i.e. when it goes out of scope; see RAII). If it is a member of a class (not a pointer, but a full member), then this will happen when the containing object is destroyed.

class A
{
    char *someHeapMemory;
public:
    A() : someHeapMemory(new char[1000]) {}
    ~A() { delete[] someHeapMemory; }
};

class B
{
    A* APtr;
public:
    B() : APtr(new A()) {}
    ~B() { delete APtr; }
};

class C
{
    A Amember;
public:
    C() : Amember() {}
    ~C() {} // A is freed / destructed automatically.
};

int main()
{
    B* BPtr = new B();
    delete BPtr; // Calls ~B() which calls ~A() 
    C *CPtr = new C();
    delete CPtr;
    B b;
    C c;
} // b and c are freed/destructed automatically

In the above example, every delete and delete[] is needed. And no delete is needed (or indeed able to be used) where I did not use it.

auto_ptr, unique_ptr and shared_ptr etc... are great for making this lifetime management much easier:

class A
{
    shared_array<char> someHeapMemory;
public:
    A() : someHeapMemory(new char[1000]) {}
    ~A() { } // someHeapMemory is delete[]d automatically
};

class B
{
    shared_ptr<A> APtr;
public:
    B() : APtr(new A()) {}
    ~B() {  } // APtr is deleted automatically
};

int main()
{
    shared_ptr<B> BPtr = new B();
} // BPtr is deleted automatically

I am using anaconda for the same.

I installed graphviz using conda install graphviz in anaconda prompt. and then installed pip install graphviz in the same command prompt. It worked for me.

I don't know of any way doing this in SQL Developer. You can see all the other schemas and their objects (if you have the correct privileges) when looking in "Other Users" -> "< Schemaname >".

In your case, either use the method described above or create a new connection for the schema in which you want to work or create synonyms for all the tables you wish to access.

If you would work in SQL*Plus, issuing ALTER SESSION SET CURRENT_SCHEMA=MY_NAME would set your current schema (This is probably what your DBA means).

subversion will corrupt my project file after a svn up on an almost weekly basis. I'm trying to figure out why it does this right now and came across this problem.

Thanks All! I am combined feedback and finally manage to convert from text input ( string ) to Integer. Plus it could tell me whether the input is integer :)

NSNumberFormatter * f = [[NSNumberFormatter alloc] init];
[f setNumberStyle:NSNumberFormatterDecimalStyle];
NSNumber * myNumber = [f numberFromString:thresholdInput.text];

int minThreshold = [myNumber intValue]; 

NSLog(@"Setting for minThreshold %i", minThreshold);

if ((int)minThreshold < 1 )
{
    NSLog(@"Not a number");
}
else
{
    NSLog(@"Setting for integer minThreshold %i", minThreshold);
}
[f release];

In JupyterNotebook cell, Simply you can use:

%%html
<style type='text/css'>
.CodeMirror{
font-size: 17px;
</style>

The easiest way is to use a for loop template tag.

Given the view:

def MyView(request):
    ...
    query_results = YourModel.objects.all()
    ...
    #return a response to your template and add query_results to the context

You can add a snippet like this your template...

<table>
    <tr>
        <th>Field 1</th>
        ...
        <th>Field N</th>
    </tr>
    {% for item in query_results %}
    <tr> 
        <td>{{ item.field1 }}</td>
        ...
        <td>{{ item.fieldN }}</td>
    </tr>
    {% endfor %}
</table>

This is all covered in Part 3 of the Django tutorial. And here's Part 1 if you need to start there.

I won't address the READ UNCOMMITTED argument, just your original question.

Yes, you need WITH(NOLOCK) on each table of the join. No, your queries are not the same.

Try this exercise. Begin a transaction and insert a row into table1 and table2. Don't commit or rollback the transaction yet. At this point your first query will return successfully and include the uncommitted rows; your second query won't return because table2 doesn't have the WITH(NOLOCK) hint on it.

I am using XAMPP and came across the same error. I had done all those steps, added environmental variables path, copied the dll's every directory possible, to /php, /apache/bin, /system32, /syswow64, etc.. but still got this error.

Then after checking the apache error log, I noticed the issue with using brackets in path.

PHP: syntax error, unexpected '(' in C:\Program Files (other)\xampp\php\php.ini on line 707 0 server certificate does NOT include an ID which matches the server name

If you have installed the server in "Program Files (x86)" directory, the same error might occur due to the non-escaped brackets.

To fix this, open php.ini file and locate the line containing "include_path" and enclose the path with double quotes to fix this error.

include_path="C:\Program Files (other)\xampp\php\PEAR"

For those who don't know where to find the file they're talking about. On my machine (OSX) it is in:

• PyCharm CE: /Applications/PyCharm CE.app/Contents/bin/idea.properties
• WebStorm: /Applications/WebStorm.app/Contents/bin/idea.properties

How about creating a custom ObjectResult class that represents an Internal Server Error like the one for OkObjectResult? You can put a simple method in your own base class so that you can easily generate the InternalServerError and return it just like you do Ok() or BadRequest().

[Route("api/[controller]")]
[ApiController]
public class MyController : MyControllerBase
{
    [HttpGet]
    [Route("{key}")]
    public IActionResult Get(int key)
    {
        try
        {
            //do something that fails
        }
        catch (Exception e)
        {
            LogException(e);
            return InternalServerError();
        }
    }
}

public class MyControllerBase : ControllerBase
{
    public InternalServerErrorObjectResult InternalServerError()
    {
        return new InternalServerErrorObjectResult();
    }

    public InternalServerErrorObjectResult InternalServerError(object value)
    {
        return new InternalServerErrorObjectResult(value);
    }
}

public class InternalServerErrorObjectResult : ObjectResult
{
    public InternalServerErrorObjectResult(object value) : base(value)
    {
        StatusCode = StatusCodes.Status500InternalServerError;
    }

    public InternalServerErrorObjectResult() : this(null)
    {
        StatusCode = StatusCodes.Status500InternalServerError;
    }
}

In your main.xml include the following in your ListView:

android:drawSelectorOnTop="false"

android:listSelector="@android:color/darker_gray"

any of these should work

outf.write("%s" % num)

outf.write(str(num))

print >> outf, num

The first step is figuring out what the error actually is. In order to do this expand your MsBuild output to be diagnostic. This will reveal the actual command executed and hopefully the full error message as well

• Tools -> Options
• Projects and Solutions -> Build and Run
• Change "MsBuild project build output verbosity" to "Diagnostic".

Assuming your code is running inside your parent form, then something like this is probably what you're looking for:

loginForm = new SubLogin();
loginForm.StartPosition = FormStartPosition.CenterParent
loginForm.Show(this);

For the record, there's also a Form.CenterToParent() function, if you need to center it after creation for whatever reason too.

Your query will work in MYSQL if you set to disable ONLY_FULL_GROUP_BY server mode (and by default It is). But in this case, you are using different RDBMS. So to make your query work, add all non-aggregated columns to your GROUP BY clause, eg

SELECT col1, col2, SUM(col3) totalSUM
FROM tableName
GROUP BY col1, col2

Non-Aggregated columns means the column is not pass into aggregated functions like SUM, MAX, COUNT, etc..

You're accessing the latitude and longitude incorrectly.

Try

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">

var geocoder = new google.maps.Geocoder();
var address = "new york";

geocoder.geocode( { 'address': address}, function(results, status) {

  if (status == google.maps.GeocoderStatus.OK) {
    var latitude = results[0].geometry.location.lat();
    var longitude = results[0].geometry.location.lng();
    alert(latitude);
  } 
}); 
</script>

Here is a function that calculates the current position of an element within the viewport:

/**
 * Calculates the position of a given element within the viewport
 *
 * @param {string} obj jQuery object of the dom element to be monitored
 * @return {array} An array containing both X and Y positions as a number
 * ranging from 0 (under/right of viewport) to 1 (above/left of viewport)
 */
function visibility(obj) {
    var winw = jQuery(window).width(), winh = jQuery(window).height(),
        elw = obj.width(), elh = obj.height(),
        o = obj[0].getBoundingClientRect(),
        x1 = o.left - winw, x2 = o.left + elw,
        y1 = o.top - winh, y2 = o.top + elh;

    return [
        Math.max(0, Math.min((0 - x1) / (x2 - x1), 1)),
        Math.max(0, Math.min((0 - y1) / (y2 - y1), 1))
    ];
}

The return values are calculated like this:

Usage:

visibility($('#example'));  // returns [0.3742887830933581, 0.6103752759381899]

I use redbot, a great tool to see php version, but also many other useful infos like headers, encoding, keepalive and many more, try it on

http://redbot.org

I loveit !

I also upvote Neil answer : curl -I http://websitename.com

Solutions which are described above, even with unique CookieFile names, can cause a lot of problems on scale.

We had to serve a lot of authentications with this solution and our server went down because of high file read write actions.

The solution for this was to use Apache Reverse Proxy and omit CURL requests at all.

Details how to use Proxy on Apache can be found here: https://httpd.apache.org/docs/2.4/howto/reverse_proxy.html

That will only work if register_globals is on, and it should never be on (unless of course you are defining that variable somewhere else).

Try setting the form's action attribute to ?...

<form method="post" action="?">
   ...
</form>

You can also set it to be blank (""), but older WebKit versions had a bug.

Unfortunately, it is not possible out of the box since the switch-case statement expects a constant expression. To overcome this, one way would be to use enum values with the class names e.g.

public enum MyEnum {
   A(A.class.getName()), 
   B(B.class.getName()),
   C(C.class.getName());

private String refClassname;
private static final Map<String, MyEnum> ENUM_MAP;

MyEnum (String refClassname) {
    this.refClassname = refClassname;
}

static {
    Map<String, MyEnum> map = new ConcurrentHashMap<String, MyEnum>();
    for (MyEnum instance : MyEnum.values()) {
        map.put(instance.refClassname, instance);
    }
    ENUM_MAP = Collections.unmodifiableMap(map);
}

public static MyEnum get(String name) {
    return ENUM_MAP.get(name);
 }
}

With that is is possible to use the switch statement like this

MyEnum type = MyEnum.get(clazz.getName());
switch (type) {
case A:
    ... // it's A class
case B:
    ... // it's B class
case C:
    ... // it's C class
}

For me, eclipse was looking in the wrong place for the SDK Manager. To fix this I did

• Window/ Preferences/ Android/ SDK Location

NOTE: The SDK manager tells you what dir it is using near the top of the UI.

I had installed a new version of eclipse that has the ADT bundled up from the Android developer site, but when I opened eclipse it was looking at the old SDK.exe location.

I have removed JAVA_HOME variable and kept only path and classpath variables by pointing them to jdk and jre respectively. It worked for me.

On apache page: http://hc.apache.org/httpcomponents-client-ga/tutorial/html/fundamentals.html

You have something like this:

URIBuilder builder = new URIBuilder();
builder.setScheme("http").setHost("www.google.com").setPath("/search")
    .setParameter("q", "httpclient")
    .setParameter("btnG", "Google Search")
    .setParameter("aq", "f")
    .setParameter("oq", "");
URI uri = builder.build();
HttpGet httpget = new HttpGet(uri);
System.out.println(httpget.getURI());

Try swapping the elements of the pairs so you can use std::sort() as normal.

Your regex pattern should have the g modifier:

var pattern = /[somepattern]+/g;

notice the g at the end. it tells the replacer to do a global replace.

Also you dont need to use the RegExp object you can construct your pattern as above. Example pattern:

var pattern = /[0-9a-zA-Z]+/g;

a pattern is always surrounded by / on either side - with modifiers after the final /, the g modifier being the global.

EDIT: Why does it matter if pattern is a variable? In your case it would function like this (notice that pattern is still a variable):

var pattern = /[0-9a-zA-Z]+/g;
repeater.replace(pattern, "1234abc");

But you would need to change your replace function to this:

this.markup = this.markup.replace(pattern, value);

You mean you don't know the sizes of the arrays at compile-time? At run-time they could be found by the value of lastone.length and lastwo.length .

What you can do to resolve your conflict is

svn resolve --accept working -R <path>

where <path> is where you have your conflict (can be the root of your repo).

Explanations:

• resolve asks svn to resolve the conflict
• accept working specifies to keep your working files
• -R stands for recursive

Hope this helps.

EDIT:

To sum up what was said in the comments below:

• <path> should be the directory in conflict (C:\DevBranch\ in the case of the OP)
• it's likely that the origin of the conflict is
  • either the use of the svn switch command
  • or having checked the Switch working copy to new branch/tag option at branch creation
• more information about conflicts can be found in the dedicated section of Tortoise's documentation.
• to be able to run the command, you should have the CLI tools installed together with Tortoise:

The nice way to do this is to add a "test" npm script in package.json that calls mocha with the right arguments. This way your package.json also describes your test structure. It also avoids all these cross-platform issues in the other answers (double vs single quotes, "find", etc.)

To have mocha run all js files in the "test" directory:

"scripts": {
    "start": "node ./bin/www", -- not required for tests, just here for context
    "test": "mocha test/**/*.js"
  },

Then to run only the smoke tests call:

npm test

You can standardize the running of all tests in all projects this way, so when a new developer starts on your project or another, they know "npm test" will run the tests. There is good historical precedence for this (Maven, for example, most old school "make" projects too). It sure helps CI when all projects have the same test command.

Similarly, you might have a subset of faster "smoke" tests that you might want mocha to run:

"scripts": {
    "test": "mocha test/**/*.js"
    "smoketest": "mocha smoketest/**/*.js"
  },

Then to run only the smoke tests call:

npm smoketest

Another common pattern is to place your tests in the same directory as the source that they test, but call the test files *.spec.js. For example: src/foo/foo.js is tested by src/foo/foo.spec.js.

To run all the tests named *.spec.js by convention:

  "scripts": {
    "test": "mocha **/*.spec.js"
  },

Then to run all the tests call:

npm test

See the pattern here? Good. :) Consistency defeats mura.

It's because you're missing position:relative; on #contentframe

<div id="contentframe" style="position:relative; top: 160px; left: 0px;">

position:absolute; positions itself against the closest ancestor that has a position that is not static. Since the default is static that is what was causing your issue.

Ended up here to check if there was something builtin to the browser already, but it seems there isn't. This is my solution (very similar to Robert's answer):

"use strict";

const is_key_down = (() => {
    const state = {};

    window.addEventListener('keyup', (e) => state[e.key] = false);
    window.addEventListener('keydown', (e) => state[e.key] = true);

    return (key) => state.hasOwnProperty(key) && state[key] || false;
})();

You can then check if a key is pressed with is_key_down('ArrowLeft').

Eliminating the duplicate values in a sequence, but preserve the order of the remaining items. Use of general purpose generator function.

# for hashable sequence
def remove_duplicates(items):
    seen = set()
    for item in items:
        if item not in seen:
            yield item
            seen.add(item)

a = [1, 5, 2, 1, 9, 1, 5, 10]
list(remove_duplicates(a))
# [1, 5, 2, 9, 10]



# for unhashable sequence
def remove_duplicates(items, key=None):
    seen = set()
    for item in items:
        val = item if key is None else key(item)
        if val not in seen:
            yield item
            seen.add(val)

a = [ {'x': 1, 'y': 2}, {'x': 1, 'y': 3}, {'x': 1, 'y': 2}, {'x': 2, 'y': 4}]
list(remove_duplicates(a, key=lambda d: (d['x'],d['y'])))
# [{'x': 1, 'y': 2}, {'x': 1, 'y': 3}, {'x': 2, 'y': 4}]

You can better understand what Looper is in the context of GUI framework. Looper is made to do 2 things.

1) Looper transforms a normal thread, which terminates when its run() method return, into something run continuously until Android app is running, which is needed in GUI framework (Technically, it still terminates when run() method return. But let me clarify what I mean in below).

2) Looper provides a queue where jobs to be done are enqueued, which is also needed in GUI framework.

As you may know, when an application is launched, the system creates a thread of execution for the application, called “main”, and Android applications normally run entirely on a single thread by default the “main thread”. But main thread is not some secret, special thread. It's just a normal thread similar to threads you create with new Thread() code, which means it terminates when its run() method return! Think of below example.

public class HelloRunnable implements Runnable {
    public void run() {
        System.out.println("Hello from a thread!");
    }

    public static void main(String args[]) {
        (new Thread(new HelloRunnable())).start();
    }
}

Now, let's apply this simple principle to Android apps. What would happen if an Android app runs on normal thread? A thread called "main" or "UI" or whatever starts your application, and draws all UI. So, the first screen is displayed to users. So what now? The main thread terminates? No, it shouldn’t. It should wait until users do something, right? But how can we achieve this behavior? Well, we can try with Object.wait() or Thread.sleep(). For example, main thread finishes its initial job to display first screen, and sleeps. It awakes, which means interrupted, when a new job to do is fetched. So far so good, but at this moment we need a queue-like data structure to hold multiple jobs. Think about a case when a user touches screen serially, and a task takes longer time to finish. So, we need to have a data structure to hold jobs to be done in first-in-first-out manner. Also, you may imagine, implementing ever-running-and-process-job-when-arrived thread using interrupt is not easy, and leads to complex and often unmaintainable code. We'd rather create a new mechanism for such purpose, and that is what Looper is all about. The official document of Looper class says, "Threads by default do not have a message loop associated with them", and Looper is a class "used to run a message loop for a thread". Now you can understand what it means.

To make things more clear, let's check the code where main thread is transformed. It all happens in ActivityThread class. In its main() method, you can find below code, which turns a normal main thread into something what we need.

public final class ActivityThread {
    ...
    public static void main(String[] args) {
        ...
        Looper.prepareMainLooper();
        Looper.loop();
        ...
    }
}

and Looper.loop() method loop infinitely and dequeue a message and process one at a time:

public static void loop() {
    ...
    for (;;) {
        Message msg = queue.next(); // might block
        if (msg == null) {
            // No message indicates that the message queue is quitting.
            return;
        }
        ...
        msg.target.dispatchMessage(msg);
        ...
    }
}

So, basically Looper is a class that is made to address a problem that occurs in GUI framework. But this kind of needs can also happen in other situation as well. Actually it is a pretty famous pattern for multi threads application, and you can learn more about it in "Concurrent Programming in Java" by Doug Lea(Especially, chapter 4.1.4 "Worker Threads" would be helpful). Also, you can imagine this kind of mechanism is not unique in Android framework, but all GUI framework may need somewhat similar to this. You can find almost same mechanism in Java Swing framework.

#include <stdio.h>

#define BLUE(string) "\x1b[34m" string "\x1b[0m"
#define RED(string) "\x1b[31m" string "\x1b[0m"

int main(void)
{
    printf("this is " RED("red") "!\n");

    // a somewhat more complex ...
    printf("this is " BLUE("%s") "!\n","blue");

    return 0;
}

reading Wikipedia:

• \x1b[0m resets all attributes
• \x1b[31m sets foreground color to red
• \x1b[44m would set the background to blue.
• both : \x1b[31;44m
• both but inversed : \x1b[31;44;7m
• remember to reset afterwards \x1b[0m ...

Using LocalTime in Java 8, LocalTime has many useful methods like getHour() or the getMinute() method,

For example,

LocalTime intime = LocalTime.parse(inputString, DateTimeFormatter.ofPattern("h:m a"));
String outtime = intime.format(DateTimeFormatter.ISO_LOCAL_TIME);

In some cases, First line alone can do the required parsing

Use the Python list insert() method. Usage:

#Syntax

The syntax for the insert() method -

list.insert(index, obj)

#Parameters

• index - This is the Index where the object obj need to be inserted.
• obj - This is the Object to be inserted into the given list.

#Return Value This method does not return any value, but it inserts the given element at the given index.

Example:

a = [1,2,4,5]

a.insert(2,3)

print(a)

Returns [1, 2, 3, 4, 5]

CLASSPATH is an environment variable (i.e., global variables of the operating system available to all the processes) needed for the Java compiler and runtime to locate the Java packages used in a Java program. (Why not call PACKAGEPATH?) This is similar to another environment variable PATH, which is used by the CMD shell to find the executable programs.

CLASSPATH can be set in one of the following ways:

CLASSPATH can be set permanently in the environment: In Windows, choose control panel ? System ? Advanced ? Environment Variables ? choose "System Variables" (for all the users) or "User Variables" (only the currently login user) ? choose "Edit" (if CLASSPATH already exists) or "New" ? Enter "CLASSPATH" as the variable name ? Enter the required directories and JAR files (separated by semicolons) as the value (e.g., ".;c:\javaproject\classes;d:\tomcat\lib\servlet-api.jar"). Take note that you need to include the current working directory (denoted by '.') in the CLASSPATH.

To check the current setting of the CLASSPATH, issue the following command:

> SET CLASSPATH

CLASSPATH can be set temporarily for that particular CMD shell session by issuing the following command:

> SET CLASSPATH=.;c:\javaproject\classes;d:\tomcat\lib\servlet-api.jar

Instead of using the CLASSPATH environment variable, you can also use the command-line option -classpath or -cp of the javac and java commands, for example,

> java –classpath c:\javaproject\classes com.abc.project1.subproject2.MyClass3

I'd seriously recommend installing MacVim via MacPorts (sudo port install MacVim).

When installed, MacPorts automatically updates your profile to include /opt/local/bin in your path, and so when mvim is installed as /opt/local/bin/mvim during the install of MacVim you'll find it ready to use straight away.

When you install the MacVim port the MacVim.app bundle is installed in /Applications/MacPorts for you too.

A good thing about going the MacPorts route is that you'll also be able to install git too (sudo port install git-core) and many many other ports. Highly recommended.
