You must use the same Tokenizer you used to build your model!

Else this will give different vector to each word.

Then, I am using:

phrase = "not good"
tokens = myTokenizer.texts_to_matrix([phrase])

model.predict(np.array(tokens))

// its with strongboard 
@IBOutlet weak var mapView: MKMapView!

//12.9767415,77.6903967 - exact location latitude n longitude location 
let cooridinate = CLLocationCoordinate2D(latitude: 12.9767415 , longitude: 77.6903967)
let  spanDegree = MKCoordinateSpan(latitudeDelta: 0.2,longitudeDelta: 0.2)
let region = MKCoordinateRegion(center: cooridinate , span: spanDegree)
mapView.setRegion(region, animated: true)

$(function() {
     var pgurl = window.location.href.substr(window.location.href.lastIndexOf("/")+1);
     $(".nav li").each(function(){
          if($('a',this).attr("href") == pgurl || $('a', this).attr("href") == '' )
          $(this).addClass("active");
     })
});

To prevent the problem from occurring, you must perform a graceful shutdown of the server from the command line rather than powering off the server.

# shutdown -h now

This will stop the running services before powering down the machine.

Based on Centos, an additional method for getting it back up again when you run into this problem is to move mysql.sock:

# mv /var/lib/mysql/mysql.sock /var/lib/mysql/mysql.sock.bak

# service mysqld start

Restarting the service creates a new entry called mqsql.sock

No need to use fancy unicode char exmaples to show the difference. Here's one simple example I found out today which is surprising, consisting of only ASCII characters.

According to the ASCII table, 0 (0x48) is smaller than _ (0x95) when compared ordinally. InvariantCulture would say the opposite (PowerShell code below):

PS> [System.StringComparer]::Ordinal.Compare("_", "0")
47
PS> [System.StringComparer]::InvariantCulture.Compare("_", "0")
-1

Why are you combining GET and POST? Use one or the other.

$.ajax({
    type: 'post',
    data: {
        timestamp: timestamp,
        uid: uid
        ...
    }
});

php:

$uid =$_POST['uid'];

Or, just format your request properly (you're missing the ampersands for the get parameters).

url:"getdata.php?timestamp="+timestamp+"&uid="+id+"&uname="+name,

np.average takes an optional weight parameter. If it is not supplied they are equivalent. Take a look at the source code: Mean, Average

np.mean:

try:
    mean = a.mean
except AttributeError:
    return _wrapit(a, 'mean', axis, dtype, out)
return mean(axis, dtype, out)

np.average:

...
if weights is None :
    avg = a.mean(axis)
    scl = avg.dtype.type(a.size/avg.size)
else:
    #code that does weighted mean here

if returned: #returned is another optional argument
    scl = np.multiply(avg, 0) + scl
    return avg, scl
else:
    return avg
...

Use the keyword next. If you do not want to continue to the next item, use break.

When next is used within a block, it causes the block to exit immediately, returning control to the iterator method, which may then begin a new iteration by invoking the block again:

f.each do |line|              # Iterate over the lines in file f
  next if line[0,1] == "#"    # If this line is a comment, go to the next
  puts eval(line)
end

When used in a block, break transfers control out of the block, out of the iterator that invoked the block, and to the first expression following the invocation of the iterator:

f.each do |line|             # Iterate over the lines in file f
  break if line == "quit\n"  # If this break statement is executed...
  puts eval(line)
end
puts "Good bye"              # ...then control is transferred here

And finally, the usage of return in a block:

return always causes the enclosing method to return, regardless of how deeply nested within blocks it is (except in the case of lambdas):

def find(array, target)
  array.each_with_index do |element,index|
    return index if (element == target)  # return from find
  end
  nil  # If we didn't find the element, return nil
end

I had this issue and I solved it by creating a directory in mysite folder to hold my db.sqlite3 file. so I did /home/user/src/mysite/database/db.sqlite3. In my django setting file I change my

 DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.sqlite3',
    'NAME': "/home/user/src/mysite/database/db.sqlite3" ,
}}

I did this to make Django aware that I am storing my database in a sub directory of the base directory, which mysite in my case. Now you need to grant the permission to apache to be able read write the database.

chown user:www-data database/db.sqlite3
chown user:www-data database 
chmod 755 database
 chmod 755 database/db.sqlite3

This solved my problem. Here is a list of the different permissions. You can use choose the one that fits you but avoid 777 and 666

-rw------- (600) -- Only the user has read and write permissions.

-rw-r--r-- (644) -- Only user has read and write permissions; the group and others can read only.

-rwx------ (700) -- Only the user has read, write and execute permissions.

-rwxr-xr-x (755) -- The user has read, write and execute permissions; the group and others can only read and execute.

-rwx--x--x (711) -- The user has read, write and execute permissions; the group and others can only execute.

-rw-rw-rw- (666) -- Everyone can read and write to the file. Bad idea.

-rwxrwxrwx (777) -- Everyone can read, write and execute. Another bad idea.

Here are a couple common settings for directories:

drwx------ (700) -- Only the user can read, write in this directory.

drwxr-xr-x (755) -- Everyone can read the directory, but its contents can only be changed by the user.

here is a link to an article to [learn more][1]

[1]: http://ftp.kh.edu.tw/Linux/Redhat/en_6.2/doc/gsg/s1-navigating-chmodnum.htm#:~:text=%2Drwxr%2Dxr%2Dx%20(,and%20others%20can%20only%20execute.

This can be done in [N + log(N) - 2] time, which is slightly better than the loose upper bound of 2N (which can be thought of O(N) too).

The trick is to use binary recursive calls and "tennis tournament" algorithm. The winner (the largest number) will emerge after all the 'matches' (takes N-1 time), but if we record the 'players' of all the matches, and among them, group all the players that the winner has beaten, the second largest number will be the largest number in this group, i.e. the 'losers' group.

The size of this 'losers' group is log(N), and again, we can revoke the binary recursive calls to find the largest among the losers, which will take [log(N) - 1] time. Actually, we can just linearly scan the losers group to get the answer too, the time budget is the same.

Below is a sample python code:

def largest(L):
    global paris
    if len(L) == 1:
        return L[0]
    else:
        left = largest(L[:len(L)//2])
        right = largest(L[len(L)//2:])
        pairs.append((left, right))
        return max(left, right)

def second_largest(L):
    global pairs
    biggest = largest(L)
    second_L = [min(item) for item in pairs if biggest in item]

    return biggest, largest(second_L)  



if __name__ == "__main__":
    pairs = []
    # test array
    L = [2,-2,10,5,4,3,1,2,90,-98,53,45,23,56,432]    

    if len(L) == 0:
        first, second = None, None
    elif len(L) == 1:
        first, second = L[0], None
    else:
        first, second = second_largest(L)

    print('The largest number is: ' + str(first))
    print('The 2nd largest number is: ' + str(second))

From the PHP Manual:

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

mysqli_connect()

PDO::__construct()

use MySQLi or PDO

<?php
$con = mysqli_connect('localhost', 'username', 'password', 'database');

And you can combine same events/functions in this way:

$("table.planning_grid").on({
    mouseenter: function() {
        // Handle mouseenter...
    },
    mouseleave: function() {
        // Handle mouseleave...
    },
    'click blur paste' : function() {
        // Handle click...
    }
}, "input");

In Flutter

Update version:1.0.0+1 in pubspec.yaml.

The default version number of the app is 1.0.0. To update it, navigate to the pubspec.yaml file and update the following line:

version: 1.0.0+1

+1 (the number after the +) represents the versionCode such as 1, 2, 3, etc.

So increase it one by one, like this

version: 1.0.1+2

The version number is three numbers separated by dots, such as 1.0.0 in the example above, followed by an optional build number such as 1 in the example above, separated by a +.

Both the version and the build number may be overridden in Flutter’s build by specifying --build-name and --build-number, respectively.

In Android, build-name is used as versionName while build-number used as versionCode. For more information, see Version your app

After updating the version number in the pubspec file, run flutter pub get from the top of the project, or use the Pub get button in your IDE. This updates the versionName and versionCode in the local.properties file, which are later updated in the build.gradle file when you rebuild the Flutter app.

This works for mysql version 5.5.32

ALTER TABLE  `tablename` ADD UNIQUE (`column1` ,`column2`);

If you just use round then the two end numbers (1 and 9) will occur less frequently, to get an even distribution of integers between 1 and 9 then:

SELECT MOD(Round(DBMS_RANDOM.Value(1, 99)), 9) + 1 FROM DUAL

To use requests (or any other blocking libraries) with asyncio, you can use BaseEventLoop.run_in_executor to run a function in another thread and yield from it to get the result. For example:

import asyncio
import requests

@asyncio.coroutine
def main():
    loop = asyncio.get_event_loop()
    future1 = loop.run_in_executor(None, requests.get, 'http://www.google.com')
    future2 = loop.run_in_executor(None, requests.get, 'http://www.google.co.uk')
    response1 = yield from future1
    response2 = yield from future2
    print(response1.text)
    print(response2.text)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

This will get both responses in parallel.

With python 3.5 you can use the new await/async syntax:

import asyncio
import requests

async def main():
    loop = asyncio.get_event_loop()
    future1 = loop.run_in_executor(None, requests.get, 'http://www.google.com')
    future2 = loop.run_in_executor(None, requests.get, 'http://www.google.co.uk')
    response1 = await future1
    response2 = await future2
    print(response1.text)
    print(response2.text)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

See PEP0492 for more.

If you are using jQuery you can easily check the type of any element.

    function(elementID){    
    var type = $(elementId).attr('type');
    if(type == "text") //inputBox
     console.log("input text" + $(elementId).val().size());
   }

similarly you can check the other types and take appropriate action.

While there are JS implementations of the MD5 algorithm, older browsers are generally unable to read files from the local filesystem.

I wrote that in 2009. So what about new browsers?

With a browser that supports the FileAPI, you *can * read the contents of a file - the user has to have selected it, either with an <input> element or drag-and-drop. As of Jan 2013, here's how the major browsers stack up:

• FF 3.6 supports FileReader, FF4 supports even more file based functionality
• Chrome has supported the FileAPI since version 7.0.517.41
• Internet Explorer 10 has partial FileAPI support
• Opera 11.10 has partial support for FileAPI
• Safari - I couldn't find a good official source for this, but this site suggests partial support from 5.1, full support for 6.0. Another article reports some inconsistencies with the older Safari versions

I'm working on MySQL5.7.11 on Debian, the command that worked for me to see the directory is:

mysql> SELECT @@global.secure_file_priv;

I'm way late, but check out Quandl. They have an API for stock prices and fundamentals.

Here's an example call, using Quandl-api download in csv

example:

https://www.quandl.com/api/v1/datasets/WIKI/AAPL.csv?column=4&sort_order=asc&collapse=quarterly&trim_start=2012-01-01&trim_end=2013-12-31

They support these languages. Their source data comes from Yahoo Finance, Google Finance, NSE, BSE, FSE, HKEX, LSE, SSE, TSE and more (see here).

I found the following css in order to style a Bootstrap input for a jquery autocomplete:

https://gist.github.com/daz/2168334#file-style-scss

public static bool CompareDateTimes(this DateTime firstDate, DateTime secondDate) 
{
   return firstDate.Day == secondDate.Day && firstDate.Month == secondDate.Month && firstDate.Year == secondDate.Year;
}

This should do the trick

var start = $('#start_date').val();
var end = $('#end_date').val();

// end - start returns difference in milliseconds 
var diff = new Date(end - start);

// get days
var days = diff/1000/60/60/24;

Example

var start = new Date("2010-04-01"),
    end   = new Date(),
    diff  = new Date(end - start),
    days  = diff/1000/60/60/24;

days; //=> 8.525845775462964

First of all, thank you all for your inputs. I tweak my Query - 1 and got my desired result. Gordon Linoff is right, PRINT was messing up my query so I modified it as following:

Modified Query - 1:

SET ROWCOUNT 5
WHILE (1 = 1)
  BEGIN
    BEGIN TRANSACTION

        UPDATE TableName 
        SET Value = 'abc1' 
        WHERE Parameter1 = 'abc' AND Parameter2 = 123

        IF @@ROWCOUNT = 0
          BEGIN
                COMMIT TRANSACTION
                BREAK
          END
    COMMIT TRANSACTION
  END
SET ROWCOUNT  0

Output:

(5 row(s) affected)

(5 row(s) affected)

(4 row(s) affected)

(0 row(s) affected)

Using junit4 and Hamcrest you get a concise method of comparing arrays. It also gives details of where the error is in the failure trace.

import static org.junit.Assert.*
import static org.hamcrest.CoreMatchers.*;

//...

assertThat(result, is(new int[] {56, 100, 2000}));

Failure Trace output:

java.lang.AssertionError: 
   Expected: is [<56>, <100>, <2000>]
   but: was [<55>, <100>, <2000>]

You'd be much better off using the same array with both lists, and creating angular filters to achieve your goal.

http://docs.angularjs.org/guide/dev_guide.templates.filters.creating_filters

Rough, untested code follows:

appModule.filter('checked', function() {
    return function(input, checked) {
        if(!input)return input;
        var output = []
        for (i in input){
            var item = input[i];
            if(item.checked == checked)output.push(item);
        }
        return output
    }
});

and the view (i added an "uncheck" button too)

<div id="AddItem">
     <h3>Add Item</h3>

    <input value="1" type="number" placeholder="1" ng-model="itemAmount">
    <input value="" type="text" placeholder="Name of Item" ng-model="itemName">
    <br/>
    <button ng-click="addItem()">Add to list</button>
</div>
<!-- begin: LIST OF CHECKED ITEMS -->
<div id="CheckedList">
     <h3>Checked Items: {{getTotalCheckedItems()}}</h3>

     <h4>Checked:</h4>

    <table>
        <tr ng-repeat="item in items | checked:true" class="item-checked">
            <td><b>amount:</b> {{item.amount}} -</td>
            <td><b>name:</b> {{item.name}} -</td>
            <td> 
               <i>this item is checked!</i>
               <button ng-click="item.checked = false">uncheck item</button>

            </td>
        </tr>
    </table>
</div>
<!-- end: LIST OF CHECKED ITEMS -->
<!-- begin: LIST OF UNCHECKED ITEMS -->
<div id="UncheckedList">
     <h3>Unchecked Items: {{getTotalItems()}}</h3>

     <h4>Unchecked:</h4>

    <table>
        <tr ng-repeat="item in items | checked:false" class="item-unchecked">
            <td><b>amount:</b> {{item.amount}} -</td>
            <td><b>name:</b> {{item.name}} -</td>
            <td>
                <button ng-click="item.checked = true">check item</button>
            </td>
        </tr>
    </table>
</div>
<!-- end: LIST OF ITEMS -->

Then you dont need the toggle methods etc in your controller

The new networking feature allows you to connect to containers by their name, so if you create a new network, any container connected to that network can reach other containers by their name. Example:

1) Create new network

$ docker network create <network-name>       

2) Connect containers to network

$ docker run --net=<network-name> ...

or

$ docker network connect <network-name> <container-name>

3) Ping container by name

docker exec -ti <container-name-A> ping <container-name-B> 

64 bytes from c1 (172.18.0.4): icmp_seq=1 ttl=64 time=0.137 ms
64 bytes from c1 (172.18.0.4): icmp_seq=2 ttl=64 time=0.073 ms
64 bytes from c1 (172.18.0.4): icmp_seq=3 ttl=64 time=0.074 ms
64 bytes from c1 (172.18.0.4): icmp_seq=4 ttl=64 time=0.074 ms

See this section of the documentation;

Note: Unlike legacy links the new networking will not create environment variables, nor share environment variables with other containers.

This feature currently doesn't support aliases

Using LINQ to xml if you are using framework 3.5

using System.Xml.Linq;

XDocument xmlFile = XDocument.Load("books.xml"); 
var query = from c in xmlFile.Elements("catalog").Elements("book")    
            select c; 
foreach (XElement book in query) 
{
    book.Attribute("attr1").Value = "MyNewValue";
}
xmlFile.Save("books.xml");

You can use the button :

1 - make the text empty

2 - set the background for it

+3 - you can use the selector to more useful and nice button

About the imagebutton you can set the image source and the background the same picture and it must be (*.png) when you do it you can make any design for the button

and for more beauty button use the selector //just Google it ;)

<ScrollViewer MaxHeight="50"  
              Width="Auto" 
              HorizontalScrollBarVisibility="Disabled"
              VerticalScrollBarVisibility="Auto">
     <TextBlock Text="{Binding Path=}" 
                Style="{StaticResource TextStyle_Data}" 
                TextWrapping="Wrap" />
</ScrollViewer>

I am doing this in another way by putting MaxHeight in ScrollViewer.

Just Adjust the MaxHeight to show more or fewer lines of text. Easy.

I figured out that I was not generating Credentials for the right app type.
If you're using Postman to test Google oAuth 2 APIs, select
Credentials -> Add credentials -> OAuth2.0 client ID -> Web Application.

I found this worked best for my usecase:

<i class="btn btn-light fa fa-dribbble fa-4x" href="#"></i>
<i class="btn btn-light fa fa-behance-square fa-4x" href="#"></i>
<i class="btn btn-light fa fa-linkedin-square fa-4x" href="#"></i>
<i class="btn btn-light fa fa-twitter-square fa-4x" href="#"></i>
<i class="btn btn-light fa fa-facebook-square fa-4x" href="#"></i>

Unique Validation With Different Column ID In Laravel

'UserEmail'=>"required|email|unique:users,UserEmail,$userID,UserID"

after passing the vector by reference

swap(vector[position],vector[otherPosition]);

will produce the expected result.

Use this following code:

    let intVal=56
    let floatval:Double=56.897898
    let doubleValue=89.0
    let explicitDaouble:Double=89.56
    let stringValue:"Hello"

    let stringValue="String:\(stringValue) Integer:\(intVal) Float:\(floatval) Double:\(doubleValue) ExplicitDouble:\(explicitDaouble) "

ES2015:

let el = document.getElementById("el");
let handler =()=> console.log("changed");
['change', 'keyup', 'cut'].forEach(event => el.addEventListener(event, handler));

Only dictionaries, Lists and primitive object types (int, string, bool) are available in JSON.

DateFormat.format only works on Date values.

You should use two SimpleDateFormat objects: one for parsing, and one for formatting. For example:

// Note, MM is months, not mm
DateFormat outputFormat = new SimpleDateFormat("MM/yyyy", Locale.US);
DateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX", Locale.US);

String inputText = "2012-11-17T00:00:00.000-05:00";
Date date = inputFormat.parse(inputText);
String outputText = outputFormat.format(date);

EDIT: Note that you may well want to specify the time zone and/or locale in your formats, and you should also consider using Joda Time instead of all of this to start with - it's a much better date/time API.

Try word.matches("^[0-9,;]+$");

I had a similar problem for xml. Just passing the error and solution (edited Jonathon version).

Code:

HttpGet xmlGet = new HttpGet( xmlContent );

Xml format:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<employee>
    <code>CA</code>
    <name>Cath</name>
    <salary>300</salary>
</employee>

Error:

java.lang.IllegalArgumentException: Illegal character in path at index 0: <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<contents>
    <portalarea>CA</portalarea>
    <portalsubarea>Cath</portalsubarea>
    <direction>Navigator</direction>

    at org.apache.http.client.methods.HttpGet.<init>(HttpGet.java:69)
    at de.vogella.jersey.first.Hello.validate(Hello.java:56)

Not Exactly perfect Solution: ( error vanished for that instance )

String theXml = URLEncoder.encode( xmlContent, "UTF-8" );
HttpGet xmlGet = new HttpGet( theXml );

Any idea What i should be doing ? It just cleared passed but had problem while doing this

HttpResponse response = httpclient.execute( xmlGet );

For the non-selected radio buttons, flag them as disabled. This prevents them from responding to user input and clearing out the checked radio button. For example:

<input type="radio" name="var" checked="yes" value="Yes"></input>

I just ran into the exact same problem while configuring my server 2008 and windows 7 vm's in VMware workstation 9. what helped is disabling the firewall and running the following command at the windows command prompt

netsh firewall set icmpsetting 8 enable

at that point I was able to ping one VM then both once I performed the command on both. this differnce between our scenarios is I have my VM configured using Bridged connections

First, one thing to recognize about OS X is that it is built on Unix. This is where the .bash_profile comes in. When you start the Terminal app in OS X you get a bash shell by default. The bash shell comes from Unix and when it loads it runs the .bash_profile script. You can modify this script for your user to change your settings. This file is located at:

~/.bash_profile

Update for Mavericks

OS X Mavericks does not use the environment.plist - at least not for OS X windows applications. You can use the launchd configuration for windowed applications. The .bash_profile is still supported since that is part of the bash shell used in Terminal.

Lion and Mountain Lion Only

OS X windowed applications receive environment variables from the your environment.plist file. This is likely what you mean by the ".plist" file. This file is located at:

~/.MacOSX/environment.plist

If you make a change to your environment.plist file then OS X windows applications, including the Terminal app, will have those environment variables set. Any environment variable you set in your .bash_profile will only affect your bash shells.

Generally I only set variables in my .bash_profile file and don't change the .plist file (or launchd file on Mavericks). Most OS X windowed applications don't need any custom environment. Only when an application actually needs a specific environment variable do I change the environment.plist (or launchd file on Mavericks).

It sounds like what you want is to change the environment.plist file, rather than the .bash_profile.

One last thing, if you look for those files, I think you will not find them. If I recall correctly, they were not on my initial install of Lion.

Edit: Here are some instructions for creating a plist file.

1. Open Xcode
2. Select File -> New -> New File...
3. Under Mac OS X select Resources
4. Choose a plist file
5. Follow the rest of the prompts

To edit the file, you can Control-click to get a menu and select Add Row. You then can add a key value pair. For environment variables, the key is the environment variable name and the value is the actual value for that environment variable.

Once the plist file is created you can open it with Xcode to modify it anytime you wish.

document.getElementById("serverTime").innerHTML = ...;

This code will remove your whole cache of the application, You can check on app setting and open the app info and check the size of cache. Once you will use this code your cache size will be 0KB . So it and enjoy the clean cache.

 if (Build.VERSION_CODES.KITKAT <= Build.VERSION.SDK_INT) {
            ((ActivityManager) context.getSystemService(ACTIVITY_SERVICE))
                    .clearApplicationUserData();
            return;
        }

Until we have N primes, take natural numbers one by one, check whether any of the so-far-collected-primes divide it.

If none does, "yay", we have a new prime...

that's it.

>>> def generate_n_primes(N):
...     primes  = []
...     chkthis = 2
...     while len(primes) < N:
...         ptest    = [chkthis for i in primes if chkthis%i == 0]
...         primes  += [] if ptest else [chkthis]
...         chkthis += 1
...     return primes
...
>>> print generate_n_primes(15)
[2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47]

Similar to Underscore library there is another library called as 'lodash' that has one method "orderBy" which takes in the parameter to determine in which order to sort it. You can use it like

_.orderBy('collection', 'propertyName', 'desc')

For some reason, it's not documented on the website docs.

if the statement after assert is true then the program continues , but if the statement after assert is false then the program gives an error. Simple as that.

e.g.:

assert 1>0   #normal execution
assert 0>1   #Traceback (most recent call last):
             #File "<pyshell#11>", line 1, in <module>
             #assert 0>1
             #AssertionError

If you have an array of objects and want to flatten it with a node, just use this function:

function objectArray_flatten($array,$childField) {
    $result = array();
    foreach ($array as $node)
    {
        $result[] = $node;
        if(isset($node->$childField))
        {
            $result = array_merge(
                $result, 
                objectArray_flatten($node->$childField,$childField)
            );
            unset($node->$childField);
        }

    }
    return $result;
}

Try:

select concat(first_name,last_name) as "Name" from test.student

or, better:

select concat(first_name," ",last_name) as "Name" from test.student

A rather roundabout way, just for completeness:

 for /f "delims=" %i in ('type CON') do set inp=%i

Of course that requires ^Z as a terminator, and so the Johannes answer is better in all practical ways.

Laravel 419 post error is usually related with api.php and token authorization

Laravel automatically generates a CSRF "token" for each active user session managed by the application. This token is used to verify that the authenticated user is the one actually making the requests to the application.

Add this to your ajax call

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});

or you can exclude some URIs in VerifyCSRF token middleware

 protected $except = [
        '/route_you_want_to_ignore',
        '/route_group/*
    ];

If you start out with:

let array = [
    {name: "malcom", dogType: "four-legged"},
    {name: "peabody", dogType: "three-legged"},
    {name: "pablo", dogType: "two-legged"}
];

And you want a set of, say, names, you would do:

let namesSet = new Set(array.map(item => item.name));

For me the issue got fixed when I changed

<id name="personID" column="person_id">
    <generator class="native"/>
</id>

to

<id name="personID" column="person_id">
    <generator class="increment"/>
</id>

in my Person.hbm.xml.

after that I re-encountered that same error for an another field(mobno). I tried restarting my IDE, recreating the database with previous back issue got eventually fixed when I re-create my tables using (without ENGINE=InnoDB DEFAULT CHARSET=latin1; and removing underscores in the field name)

CREATE TABLE `tbl_customers` (
  `pid` bigint(20) NOT NULL,
  `title` varchar(4) NOT NULL,
  `dob` varchar(10) NOT NULL,
  `address` varchar(100) NOT NULL,
  `country` varchar(4) DEFAULT NULL,
  `hometp` int(12) NOT NULL,
  `worktp` int(12) NOT NULL,
  `mobno` varchar(12) NOT NULL,
  `btcfrom` varchar(8) NOT NULL,
  `btcto` varchar(8) NOT NULL,
  `mmname` varchar(20) NOT NULL
)

instead of

CREATE TABLE `tbl_person` (
  `person_id` bigint(20) NOT NULL,
  `person_nic` int(10) NOT NULL,
  `first_name` varchar(20) NOT NULL,
  `sur_name` varchar(20) NOT NULL,
  `person_email` varchar(20) NOT NULL,
  `person_password` varchar(512) NOT NULL,
  `mobno` varchar(10) NOT NULL DEFAULT '1',
  `role` varchar(10) NOT NULL,
  `verified` int(1) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

I probably think this due to using ENGINE=InnoDB DEFAULT CHARSET=latin1; , because I once got the error org.hibernate.engine.jdbc.spi.SqlExceptionHelper - Unknown column 'mob_no' in 'field list' even though it was my previous column name, which even do not exist in my current table. Even after backing up the database(with modified column name, using InnoDB engine) I still got that same error with old field name. This probably due to caching in that Engine.

Here’s the modern answer (valid from 2014 and on). The accepted answer was a very fine answer in 2011. These days I recommend no one uses the Date, DateFormat and SimpleDateFormat classes. It all goes more natural with the modern Java date and time API.

To get a date-time object from your millis:

    ZonedDateTime dateTime = Instant.ofEpochMilli(millis)
            .atZone(ZoneId.of("Australia/Sydney"));

If millis equals 1318388699000L, this gives you 2011-10-12T14:04:59+11:00[Australia/Sydney]. Should the code in some strange way end up on a JVM that doesn’t know Australia/Sydney time zone, you can be sure to be notified through an exception.

If you want the date-time in your string format for presentation:

String formatted = dateTime.format(DateTimeFormatter.ofPattern("dd/MM/yyyy HH:mm:ss"));

Result:

12/10/2011 14:04:59

PS I don’t know what you mean by “The above doesn't work.” On my computer your code in the question too prints 12/10/2011 14:04:59.

It's a reserved keyword (like return, filter, function, break).

Reference

Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:

But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.

Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:

PS C:\> function ex{exit}
PS C:\> new-alias ^D ex

I find using pandas MultiIndex to be the best tool for the job. If you have a list of lists lists_list, call pd.MultiIndex.from_product(lists_list) and iterate over the result (or use it in DataFrame index).

You can install the mail package in Ubuntu with below command.

For Ubuntu -:

$ sudo apt-get install -y mailutils

For CentOs-:

$ sudo yum install -y mailx

Test Mail command-:

$ echo "Mail test" | mail -s "Subject" [email protected]

I think actually nvarchar(MAX) can store approximately 1070000000 chars.

Sure there is. Here is a way to sum the values of a dictionary.

>>> d = {'key1':1,'key2':14,'key3':47}
>>> sum(d.values())
62

5.In the Format Cells box, click Custom in the Category list. 6.In the Type box, at the top of the list of formats, type [h]:mm;@ and then click OK. (That’s a colon after [h], and a semicolon after mm.) YOu can then add hours. The format will be in the Type list the next time you need it.

From MS, works well.

Here is one approach. ifelse is vectorized and it checks all rows for zero values of b and replaces est with (a - 5)/2.53 if that is the case.

df <- transform(df, est = ifelse(b == 0, (a - 5)/2.53, est))

To get both stdout and stderr, I use:

Function GetProgramOutput([string]$exe, [string]$arguments)
{
    $process = New-Object -TypeName System.Diagnostics.Process
    $process.StartInfo.FileName = $exe
    $process.StartInfo.Arguments = $arguments

    $process.StartInfo.UseShellExecute = $false
    $process.StartInfo.RedirectStandardOutput = $true
    $process.StartInfo.RedirectStandardError = $true
    $process.Start()

    $output = $process.StandardOutput.ReadToEnd()   
    $err = $process.StandardError.ReadToEnd()

    $process.WaitForExit()

    $output
    $err
}

$exe = "cmd"
$arguments = '/c echo hello 1>&2'   #this writes 'hello' to stderr

$runResult = (GetProgramOutput $exe $arguments)
$stdout = $runResult[-2]
$stderr = $runResult[-1]

[System.Console]::WriteLine("Standard out: " + $stdout)
[System.Console]::WriteLine("Standard error: " + $stderr)

zlib handles the deflate compression/decompression algorithm, but there is more than that in a ZIP file.

You can try libzip. It is free, portable and easy to use.

UPDATE: Here I attach quick'n'dirty example of libzip, with all the error controls ommited:

#include <zip.h>

int main()
{
    //Open the ZIP archive
    int err = 0;
    zip *z = zip_open("foo.zip", 0, &err);

    //Search for the file of given name
    const char *name = "file.txt";
    struct zip_stat st;
    zip_stat_init(&st);
    zip_stat(z, name, 0, &st);

    //Alloc memory for its uncompressed contents
    char *contents = new char[st.size];

    //Read the compressed file
    zip_file *f = zip_fopen(z, name, 0);
    zip_fread(f, contents, st.size);
    zip_fclose(f);

    //And close the archive
    zip_close(z);

    //Do something with the contents
    //delete allocated memory
    delete[] contents;
}

Put both and make each update the other. If the user chooses the date from the datepicker, it is easy to fix a minor misclick in the text field or visualize the choise you typed into text field in the datepicker.

The following solution is specifically for wamp environments:

This foxed me for a little while, tried all the other suggestions, $PATH etc even searched the windows registry looking for clues:

The GUI (wampmanager) indicates I have version 7 selected and yes if I phpinfo() in a page in the browser it will tell me its version 7.x.x yet php -v in the command prompt reports a 5.x.x

If you right click on the wampmanager head to icon->tools->delete unused versions and remove the old version, let it restart the services then the command prompt will return a 7.x.x

This solution means you no longer have the old version if you want to switch between php versions but there is a configuration file in C:\wamp64\wampmanager.conf which appears to specify the version to use with CLI (the parameter is called phpCliVersion). I changed it, restarted the server ... thought I had solved it but no effect perhaps I was a little impatient so I have a feeling there may be some mileage in that.

Hope that helps someone

I finally figured out a how to use Maven. From within Eclipse, create a new Maven project.

Download Maven, extract the archive, add the /bin folder to path.

Validate install from command-line by running mvn -v (will print version and java install path)

Change to the project root folder (where pom.xml is located) and run:

mvn dependency:copy-dependencies

All jar-files are downloaded to /target/dependency.

To set another output directory:

mvn dependency:copy-dependencies -DoutputDirectory="c:\temp"

Now it's possible to re-use this Maven-project for all dependency downloads by altering the pom.xml

Add jars to java project by build path -> configure build path -> libraries -> add JARs..

You can define a method in spec_helper.rb that sends a message both to Rails.logger.info and to puts and use that for debugging:

def log_test(message)
    Rails.logger.info(message)
    puts message
end

This value is from user's machine and it can be changed anytime so I think it doesn't matter, I just want to get an approximate value and then convert it to GMT in my server.

For example, I am from Taiwan and it returns "+8" for me.

Working example

JS

function timezone() {
    var offset = new Date().getTimezoneOffset();
    var minutes = Math.abs(offset);
    var hours = Math.floor(minutes / 60);
    var prefix = offset < 0 ? "+" : "-";
    return prefix+hours;
}


$('#result').html(timezone());

HTML

<div id="result"></div>

Result

+8

I have written this article about the ICommand interface.

The idea - creating a universal command that takes two delegates: one is called when ICommand.Execute (object param) is invoked, the second checks the status of whether you can execute the command (ICommand.CanExecute (object param)).

Requires the method to switching event CanExecuteChanged. It is called from the user interface elements for switching the state CanExecute() command.

public class ModelCommand : ICommand
{
    #region Constructors

    public ModelCommand(Action<object> execute)
        : this(execute, null) { }

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

    #endregion

    #region ICommand Members

    public event EventHandler CanExecuteChanged;

    public bool CanExecute(object parameter)
    {
        return _canExecute != null ? _canExecute(parameter) : true;
    }

    public void Execute(object parameter)
    {
        if (_execute != null)
            _execute(parameter);
    }

    public void OnCanExecuteChanged()
    {
        CanExecuteChanged(this, EventArgs.Empty);
    }

    #endregion

    private readonly Action<object> _execute = null;
    private readonly Predicate<object> _canExecute = null;
}

SQLite has had to sacrifice other characteristics that some people find useful, such as high concurrency, fine-grained access control, a rich set of built-in functions, stored procedures, esoteric SQL language features, XML and/or Java extensions, tera- or peta-byte scalability, and so forth

You don't need to convert your dates to timestamp before the sorting, but it's a good idea though because it will take more time to sort without it.

$data = array(
    array(
        "title" => "Another title",
        "date"  => "Fri, 17 Jun 2011 08:55:57 +0200"
    ),
    array(
        "title" => "My title",
        "date"  => "Mon, 16 Jun 2010 06:55:57 +0200"
    )
);

function sortFunction( $a, $b ) {
    return strtotime($a["date"]) - strtotime($b["date"]);
}
usort($data, "sortFunction");
var_dump($data);

Using executeUpdate() on the Query API is faster because it bypasses the persistent context .However , by-passing persistent context would cause the state of instance in the memory and the actual values of that record in the DB are not synchronized.

Consider the following example :

 Employee employee= (Employee)entityManager.find(Employee.class , 1);
 entityManager
     .createQuery("update Employee set name = \'xxxx\' where id=1")
     .executeUpdate();

After flushing, the name in the DB is updated to the new value but the employee instance in the memory still keeps the original value .You have to call entityManager.refresh(employee) to reload the updated name from the DB to the employee instance.It sounds strange if your codes still have to manipulate the employee instance after flushing but you forget to refresh() the employee instance as the employee instance still contains the original values.

Normally , executeUpdate() is used in the bulk update process as it is faster due to bypassing the persistent context

The right way to update an entity is that you just set the properties you want to updated through the setters and let the JPA to generate the update SQL for you during flushing instead of writing it manually.

   Employee employee= (Employee)entityManager.find(Employee.class ,1);
   employee.setName("Updated Name");

By far the easiest way is by using TaskFactory.FromAsync from the TPL. It's literally a couple of lines of code when used in conjunction with the new async/await keywords:

var request = WebRequest.Create("http://www.stackoverflow.com");
var response = (HttpWebResponse) await Task.Factory
    .FromAsync<WebResponse>(request.BeginGetResponse,
                            request.EndGetResponse,
                            null);
Debug.Assert(response.StatusCode == HttpStatusCode.OK);

If you can't use the C#5 compiler then the above can be accomplished using the Task.ContinueWith method:

Task.Factory.FromAsync<WebResponse>(request.BeginGetResponse,
                                    request.EndGetResponse,
                                    null)
    .ContinueWith(task =>
    {
        var response = (HttpWebResponse) task.Result;
        Debug.Assert(response.StatusCode == HttpStatusCode.OK);
    });

What you are seeing here is not an overloaded + oparator, but autoboxing behaviour. The Integer class is immutable and your code:

Integer i = 0;
i = i + 1;  

is seen by the compiler (after the autoboxing) as:

Integer i = Integer.valueOf(0);
i = Integer.valueOf(i.intValue() + 1);  

so you are correct in your conclusion that the Integer instance is changed, but not sneakily - it is consistent with the Java language definition :-)

os.path.abspath doesn't validate anything, so if we're already appending strings to __file__ there's no need to bother with dirname or joining or any of that. Just treat __file__ as a directory and start climbing:

# climb to __file__'s parent's parent:
os.path.abspath(__file__ + "/../../")

That's far less convoluted than os.path.abspath(os.path.join(os.path.dirname(__file__),"..")) and about as manageable as dirname(dirname(__file__)). Climbing more than two levels starts to get ridiculous.

But, since we know how many levels to climb, we could clean this up with a simple little function:

uppath = lambda _path, n: os.sep.join(_path.split(os.sep)[:-n])

# __file__ = "/aParent/templates/blog1/page.html"
>>> uppath(__file__, 1)
'/aParent/templates/blog1'
>>> uppath(__file__, 2)
'/aParent/templates'
>>> uppath(__file__, 3)
'/aParent'

I had the same issue recently and ended up creating a NuGet package for this.

This implements a standard heap-based priority queue. It also has all the usual niceties of the BCL collections: ICollection<T> and IReadOnlyCollection<T> implementation, custom IComparer<T> support, ability to specify an initial capacity, and a DebuggerTypeProxy to make the collection easier to work with in the debugger.

There is also an Inline version of the package which just installs a single .cs file into your project (useful if you want to avoid taking externally-visible dependencies).

More information is available on the github page.

The easiest way is this.

byte[] bytes = rs.getBytes("my_field");

  File xx = new File("filename.txt");
    if (xx.exists()) {
       System.gc();//Added this part
       Thread.sleep(2000);////This part gives the Bufferedreaders and the InputStreams time to close Completely
       xx.delete();     
    }

Cast one of the integers to a float to force the operation to be done with floating point math. Otherwise integer math is always preferred. So:

v = (float)s / t;

I was looking for the same funcionality and found this answer. However, I wanted to give you guys a quick update. It's CSS3's vmin unit.

p, li
{
  font-size: 1.2vmin;
}

vmin means 'whichever is smaller between the 1% of the ViewPort's height and the 1% of the ViewPort's width'.

My apt-get was old and busted, so I had to install from source. Here is what worked for me:

# Get the latest version from nodejs.org. At the time of this writing, it was 0.10.24
curl -o ~/node.tar.gz http://nodejs.org/dist/v0.10.24/node-v0.10.24.tar.gz
cd
tar -zxvf node.tar.gz
cd node-v0.6.18
./configure && make && sudo make install

These steps were mostly taken from joyent's installation wiki.

To avoid memory leaks you may use smart pointers whenever you can. There are basically 2 different types of smart pointers in C++

• Reference counted (e.g. boost::shared_ptr / std::tr1:shared_ptr)
• non reference counted (e.g. boost::scoped_ptr / std::auto_ptr)

The main difference is that reference counted smart pointers can be copied (and used in std:: containers) while scoped_ptr cannot. Non reference counted pointers have almost no overhead or no overhead at all. Reference counting always introduces some kind of overhead.

(I suggest to avoid auto_ptr, it has some serious flaws if used incorrectly)

I was wondering the same thing so i googled and ended up here. I did a small test in python (extremely simple) just to see and this is what I got:

For:

def for_func(n = 0):
    for n in range(500):
        n = n + 1

python -m timeit "import for_func; for_func.for_func()" > for_func.txt

10000 loops, best of 3: 40.5 usec per loop

While:

def while_func(n = 0):
    while n < 500:
        n = n + 1

python -m timeit "import while_func; while_func.while_func()" > while_func.txt

10000 loops, best of 3: 45 usec per loop

You could just use list comprehension:

property_asel = [val for is_good, val in zip(good_objects, property_a) if is_good]

or

property_asel = [property_a[i] for i in good_indices]

The latter one is faster because there are fewer good_indices than the length of property_a, assuming good_indices are precomputed instead of generated on-the-fly.

Edit: The first option is equivalent to itertools.compress available since Python 2.7/3.1. See @Gary Kerr's answer.

property_asel = list(itertools.compress(property_a, good_objects))

MSDN has a nice descriptive article on nulls and the three state logic that they engender.

In short, the SQL92 spec defines NULL as unknown, and NULL used in the following operators causes unexpected results for the uninitiated:

= operator NULL   true   false 
NULL       NULL   NULL   NULL
true       NULL   true   false
false      NULL   false  true

and op     NULL   true   false 
NULL       NULL   NULL   false
true       NULL   true   false
false      false  false  false

or op      NULL   true   false 
NULL       NULL   true   NULL
true       true   true   true
false      NULL   true   false

Comparing by performance the winner is "Loop it, sb.Append it, and do back step". Actually "enumerable and manual move next" is the same good (consider stddev).

Install-User -Username "User" -Description "LocalAdmin" -FullName "Local Admin by Powershell" -Password "Password01"
Add-GroupMember -Name 'Administrators' -Member 'User'

Disclaimer: I am the creator/maintainer of the Carbon project.

I'm also in the middle of trying to understand how this all connects.

Here's what I've found so far in XCode, but I hope to be corrected or affirmed if my assumptions are correct. I haven't found an out of the box build to xcode from cordova that correctly applies the icons. Like you I've updated all the icons listed in the config.xml but no dice.

So...

First, I usually update the config.xml in the root of the project with the one in my "www" folder (this I do out of uncertainty that the www/config.xml has any precedence or if it's even applied)

Second, I update the "Build Phases" of the project. Expand "Copy Bundle Resources", you've already noticed all of the images in "Resources/icons", "Resources/splash". You can either:

• remove all of these to avoid overwriting your images OR
• update all of these images with your own (renaming to the image name listed)

As I was working this out, you might be able to minimally just update images from the "Summary" tab.

Drag-and-drop your images from your res folders to the appropriate image in the "Summary" tab. (res/icon/ios -> App icons and res/screen/ios -> Launch Images). I do it only for iPhone since my app is iPhone only. Check "prerendered" if you don't want gloss to appear.

Then update the "icon.png" referenced in the project's plist file: PROJECT_NAME-Info.plist or in the "Info" tab when looking at the project target. Rename it to "icon-57.png" (that now lives in your project root, this was automatically added to the root when you did the drag-and-drop.

Build and you should an updated app icon.

More details here, and here but you can use

string str = "some string" ;
char *cstr = &str[0];

As of Visual Studio 2019, the modern .csproj format supports adding a condition directly on the Target element:

<Target Name="PostBuild" AfterTargets="PostBuildEvent" Condition="'$(Configuration)' == 'Debug'">
    <Exec Command="nswag run nswag.json" />
</Target>

The UI doesn't provide a way to set this up, but it does appear to safely leave the Configuration attribute in place if you make changes via the UI.

HTML:

<input id="id_ok" class="btn btn-space" value="OK" type="button">
<input id="id_cancel" class="btn btn-space" value="Cancel" type="button">

CSS:

.btn-space {
    margin-right: 5px;
}

Suppose we have a collection like below:

{ 
  "_id":"1234"
  "open":"Yes"
  "things":{
             "paper":1234
             "bottle":"Available"
             "bottle_count":40
            } 
}

We want to know if the bottle field is present or not?

Ans:

db.products.find({"things.bottle":{"$exists":true}})

You usually don't want to, because there is an exponential number of them in nontrivial graphs; if you really want to get all (simple) paths, or all (simple) cycles, you just find one (by walking the graph), then backtrack to another.

• Check if there any other instance of the server is running already
• Check if the port that will be used by the server is free.

Tested in Xcode 9.4, Swift 4 Another way to solve this issue is , You can add

override func layoutSubviews() {
        self.frame = (self.superview?.bounds)!
    }

in subview class.

You can also use ApacheCommons StringUtils.isNumeric - http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/StringUtils.html#isNumeric(java.lang.String)

Use the category below and then apply border from Quartz into your image:

[yourimage.layer setBorderColor:[[UIColor whiteColor] CGColor]];
[yourimage.layer setBorderWidth:2];

The category: UIImage+AutoScaleResize.h

#import <Foundation/Foundation.h>

@interface UIImage (AutoScaleResize)

- (UIImage *)imageByScalingAndCroppingForSize:(CGSize)targetSize;

@end

UIImage+AutoScaleResize.m

#import "UIImage+AutoScaleResize.h"

@implementation UIImage (AutoScaleResize)

- (UIImage *)imageByScalingAndCroppingForSize:(CGSize)targetSize
{
    UIImage *sourceImage = self;
    UIImage *newImage = nil;
    CGSize imageSize = sourceImage.size;
    CGFloat width = imageSize.width;
    CGFloat height = imageSize.height;
    CGFloat targetWidth = targetSize.width;
    CGFloat targetHeight = targetSize.height;
    CGFloat scaleFactor = 0.0;
    CGFloat scaledWidth = targetWidth;
    CGFloat scaledHeight = targetHeight;
    CGPoint thumbnailPoint = CGPointMake(0.0,0.0);

    if (CGSizeEqualToSize(imageSize, targetSize) == NO)
    {
        CGFloat widthFactor = targetWidth / width;
        CGFloat heightFactor = targetHeight / height;

        if (widthFactor > heightFactor)
        {
            scaleFactor = widthFactor; // scale to fit height
        }
        else
        {
            scaleFactor = heightFactor; // scale to fit width
        }

        scaledWidth  = width * scaleFactor;
        scaledHeight = height * scaleFactor;

        // center the image
        if (widthFactor > heightFactor)
        {
            thumbnailPoint.y = (targetHeight - scaledHeight) * 0.5;
        }
        else
        {
            if (widthFactor < heightFactor)
            {
                thumbnailPoint.x = (targetWidth - scaledWidth) * 0.5;
            }
        }
    }

    UIGraphicsBeginImageContext(targetSize); // this will crop

    CGRect thumbnailRect = CGRectZero;
    thumbnailRect.origin = thumbnailPoint;
    thumbnailRect.size.width  = scaledWidth;
    thumbnailRect.size.height = scaledHeight;

    [sourceImage drawInRect:thumbnailRect];

    newImage = UIGraphicsGetImageFromCurrentImageContext();

    if(newImage == nil)
    {
        NSLog(@"could not scale image");
    }

    //pop the context to get back to the default
    UIGraphicsEndImageContext();

    return newImage;
}

@end

If I understand correct you will have something like this:

<input value="default" id="sth" name="sth" type="hidden">

And to get it you have to write:

@Html.HiddenFor(m => m.sth, new { Value = "default" })

for Strongly-typed view.

I had the same error when accessing an already transactional-annotated method from a non-transactional method within the same component:

Before:
    @Component
    public class MarketObserver {
        @PersistenceContext(unitName = "maindb")
        private EntityManager em;

        @Transactional(value = "txMain", propagation = Propagation.REQUIRES_NEW)
        public void executeQuery() {
          em.persist(....);
        }


        @Async
        public void startObserving() {
          executeQuery(); //<-- Wrong
        }
    }

    //In another bean:
     marketObserver.startObserving();

I fixed the error by calling the executeQuery() on the self-referenced component:

Fixed version:
    @Component
    public class MarketObserver {
        @PersistenceContext(unitName = "maindb")
        private EntityManager em;

        @Autowired
        private GenericApplicationContext context;

        @Transactional(value = "txMain", propagation = Propagation.REQUIRES_NEW)
        public void executeQuery() {
          em.persist(....);
        }


        @Async
        public void startObserving() {
          context.getBean(MarketObserver.class).executeQuery(); //<-- Works
        }
    }

In this case, you might get some differences. Consider a line like:

"foo\tbar "

In this case, if you strip, then you'll get {"foo":"bar"} as the dictionary entry. If you don't strip, you'll get {"foo":"bar "} (note the extra space at the end)

Note that if you use line.split() instead of line.split('\t'), you'll split on every whitespace character and the "striping" will be done during splitting automatically. In other words:

line.strip().split()

is always identical to:

line.split()

but:

line.strip().split(delimiter)

Is not necessarily equivalent to:

line.split(delimiter)

I've just installed 64 bit Node.js v0.12.0 for Windows 8.1 from here. It's about 8MB and since it's an MSI you just double click to launch. It will automatically set up your environment paths etc.

Then to get the command line it's just [Win-Key]+[S] for search and then enter "node.js" as your search phrase.

Choose the Node.js Command Prompt entry NOT the Node.js entry.

Both will given you a command prompt but only the former will actually work. npm is built into that download so then just npm -whatever at prompt.

filter_input(INPUT_POST, 'var_name') instead of $_POST['var_name']
filter_input_array(INPUT_POST) instead of $_POST

Maybe adding the commands to executable file, setting +x permission and then executing?

ps aux | grep -ie amarok | awk '{print "kill -9 " $2}' > pk;chmod +x pk;./pk;rm pk

Try this:

$("span").css("pointer-events", "none");

you can enabled those back by

$("span").css("pointer-events", "auto");

In my case I had Java 7 and 8 (both x64) installed and I want to redirect to java 7 but everything is set to use Java 8. Java uses the PATH environment variable:

C:\ProgramData\Oracle\Java\javapath

as the first option to look for its folder runtime (is a hidden folder). This path contains 3 symlinks that can't be edited.

In my pc, the PATH environment variable looks like this:

C:\ProgramData\Oracle\Java\javapath;C:\Windows\System32;C:\Program Files\Java\jdk1.7.0_21\bin;

In my case, It should look like this:

C:\Windows\System32;C:\Program Files\Java\jdk1.7.0_21\bin;

I had to cut and paste the symlinks to somewhere else so java can't find them, and I can restore them later.

After setting the JAVA_HOME and JRE_HOME environment variables to the desired java folders' runtimes (in my case it is Java 7), the command java -version should show your desired java runtime. I remark there's no need to mess with the registry.

Tested on Win7 x64.

Once you are quite good in Java SE (lets say you are able to pass SCJP), I'd suggest you get junior Java programmer job and improve yourself on real world problems

Given that the trendline is straight, find the slope by choosing any two points and calculating:

(A) slope = (y1-y2)/(x1-x2)

Then you need to find the offset for the line. The line is specified by the equation:

(B) y = offset + slope*x

So you need to solve for offset. Pick any point on the line, and solve for offset:

(C) offset = y - (slope*x)

Now you can plug slope and offset into the line equation (B) and have the equation that defines your line. If your line has noise you'll have to decide on an averaging algorithm, or use curve fitting of some sort.

If your line isn't straight then you'll need to look into Curve fitting, or Least Squares Fitting - non trivial, but do-able. You'll see the various types of curve fitting at the bottom of the least squares fitting webpage (exponential, polynomial, etc) if you know what kind of fit you'd like.

Also, if this is a one-off, use Excel.

I've found a solution worked for me:

const handleDownload = async () => {
   const req = await axios({
     method: "get",
     url: `/companies/${company.id}/data`,
     responseType: "blob",
   });
   var blob = new Blob([req.data], {
     type: req.headers["content-type"],
   });
   const link = document.createElement("a");
   link.href = window.URL.createObjectURL(blob);
   link.download = `report_${new Date().getTime()}.xlsx`;
   link.click();
 };

I just point a responseType: "blob"

The Car Analogy

IDE: The MS Office of Programming. It's where you type your code, plus some added features to make you a happier programmer. (e.g. Eclipse, Netbeans). Car body: It's what you really touch, see and work on.

Library: A library is a collection of functions, often grouped into multiple program files, but packaged into a single archive file. This contains programs created by other folks, so that you don't have to reinvent the wheel. (e.g. junit.jar, log4j.jar). A library generally has a key role, but does all of its work behind the scenes, it doesn't have a GUI. Car's engine.

API: The library publisher's documentation. This is how you should use my library. (e.g. log4j API, junit API). Car's user manual - yes, cars do come with one too!

Kits

What is a kit? It's a collection of many related items that work together to provide a specific service. When someone says medicine kit, you get everything you need for an emergency: plasters, aspirin, gauze and antiseptic, etc.

SDK: McDonald's Happy Meal. You have everything you need (and don't need) boxed neatly: main course, drink, dessert and a bonus toy. An SDK is a bunch of different software components assembled into a package, such that they're "ready-for-action" right out of the box. It often includes multiple libraries and can, but may not necessarily include plugins, API documentation, even an IDE itself. (e.g. iOS Development Kit).

Toolkit: GUI. GUI. GUI. When you hear 'toolkit' in a programming context, it will often refer to a set of libraries intended for GUI development. Since toolkits are UI-centric, they often come with plugins (or standalone IDE's) that provide screen-painting utilities. (e.g. GWT)

Framework: While not the prevalent notion, a framework can be viewed as a kit. It also has a library (or a collection of libraries that work together) that provides a specific coding structure & pattern (thus the word, framework). (e.g. Spring Framework)

In the future, this problem will be solved by flexbox. Right now the browser support is dismal, but it is supported in one form or another in all current browsers.

When you face the following issue:

PHP throwing error "Warning: mysql_connect() http://function.mysql-connect: 2002 No such file or directory (trying to connect via unix:///tmp/mysql.sock)"

Set "mysql.default_socket" value in your /etc/php.ini to

 "mysql.default_socket = /var/mysql/mysql.sock". 

Then restart web service in server admin

You could convert your wildcard string to a regular expression and use that with String's matches method. Following your example:

String original = "../Test?/sample*.txt";
String regex = original.replace("?", ".?").replace("*", ".*?");

This works for your examples:

Assert.assertTrue("../Test1/sample22b.txt".matches(regex));
Assert.assertTrue("../Test4/sample-spiffy.txt".matches(regex));

And counter-examples:

Assert.assertTrue(!"../Test3/sample2.blah".matches(regex));
Assert.assertTrue(!"../Test44/sample2.txt".matches(regex));

Found it!

Your other inbuilt friend here is the system sproc SP_HELP.

sample usage ::

sp_help <MyTableName>

It returns a lot more info than you will really need, but at least 90% of your possible requirements will be catered for.

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

C11 standard §6.2.5

Paragraph - 19

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

Following program is working fine in GCC compiler.

#include<stdio.h>

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

May be other compilers generate an error.

you said:

my id coloumn is auto increment i have to get the id and convert it to another base.So i need to get the next id before insert cause converted code will be inserted too.

what you're asking for is very dangerous and will lead to a race condition. if your code is run twice at the same time by different users, they will both get 6 and their updates or inserts will step all over each other.

i suggest that you instead INSERT in to the table, get the auto_increment value using LAST_INSERT_ID(), and then UPDATE the row to set whatever value you have that depends on the auto_increment value.

I meet the same problem in windows restoring a dump file. My dump file was created with windows powershell and mysqldump like:

mysqldump db > dump.sql

The problem comes from the default encoding of powershell is UTF16. To look deeper into this, we can use "file" utility of GNU, and there exists a windows version here.
The output of my dump file is:

Little-endian UTF-16 Unicode text, with very long lines, with CRLF line terminators.

Then a conversion of coding system is needed, and there are various software can do this. For example in emacs,

M-x set-buffer-file-coding-system

then input required coding system such as utf-8.

And in the future, for a better mysqldump result, use:

mysqldump <dbname> -r <filename>

and then the output is handled by mysqldump itself but not redirection of powershell.

You can use Bootbox dialog boxes

$(document).ready(function() {

  $('#btnDelete').click(function() {
    bootbox.confirm("Are you sure want to delete?", function(result) {
      alert("Confirm result: " + result);
    });
  });
});

Plunker Demo

You can use this simple code in loop by incrementing count

cv2.imwrite("C:\Sharat\Python\Images\frame%d.jpg" % count, image)

images will be saved in the folder by name line frame0.jpg, frame1.jpg frame2.jpg etc..

You can use the set() function to convert an iterable into a set, and then use standard set update operator (|=) to add the unique values from your new set into the existing one.

>>> a = { 1, 2, 3 }
>>> b = ( 3, 4, 5 )
>>> a |= set(b)
>>> a
set([1, 2, 3, 4, 5])

You can also serve on the next-highest available port doing something like this in Python:

import SimpleHTTPServer
import SocketServer

Handler = SimpleHTTPServer.SimpleHTTPRequestHandler

port = 8000
while True:
    try:
        httpd = SocketServer.TCPServer(('', port), Handler)
        print 'Serving on port', port
        httpd.serve_forever()
    except SocketServer.socket.error as exc:
        if exc.args[0] != 48:
            raise
        print 'Port', port, 'already in use'
        port += 1
    else:
        break

If you need to do the same thing for other utilities, it may be more convenient as a bash script:

#!/usr/bin/env bash

MIN_PORT=${1:-1025}
MAX_PORT=${2:-65535}

(netstat -atn | awk '{printf "%s\n%s\n", $4, $4}' | grep -oE '[0-9]*$'; seq "$MIN_PORT" "$MAX_PORT") | sort -R | head -n 1

Set that up as a executable with the name get-free-port and you can do something like this:

someprogram --port=$(get-free-port)

That's not as reliable as the native Python approach because the bash script doesn't capture the port -- another process could grab the port before your process does (race condition) -- but still may be useful enough when using a utility that doesn't have a try-try-again approach of its own.

If you're sure that you have a valid XML, this one is simple, and avoids XML DOM trees. Maybe has some bugs, do comment if you see anything

public String prettyPrint(String xml) {
            if (xml == null || xml.trim().length() == 0) return "";

            int stack = 0;

Correlated Subquery is a sub-query that uses values from the outer query. In this case the inner query has to be executed for every row of outer query.

See example here http://en.wikipedia.org/wiki/Correlated_subquery

Simple subquery doesn't use values from the outer query and is being calculated only once:

SELECT id, first_name 
FROM student_details 
WHERE id IN (SELECT student_id
FROM student_subjects 
WHERE subject= 'Science'); 

CoRelated Subquery Example -

Query To Find all employees whose salary is above average for their department

 SELECT employee_number, name
       FROM employees emp
       WHERE salary > (
         SELECT AVG(salary)
           FROM employees
           WHERE department = emp.department);

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

I created this script to solve the problem of the class img-responsive bootstrap3, and in my case this solved!

$(document).ready(function() {

    if ($.browser.msie) {

        var pic_real_width, pic_real_height;

        var images = $(".img-responsive");

        images.each(function(){

            var img = $(this);
            $("<img/>")
            .attr("src", $(img).attr("src"))
            .load(function() {
                pic_real_width = this.width;  

                pic_stretch_width = $(img).width();  

                if(pic_stretch_width > pic_real_width)
                {
                    $(img).width(pic_real_width);
                }
            });         
        });
    }

});

I've placed this code in the document ready function and it only triggers in internet explorer. Tested in Internet Explorer 11.

var ua = window.navigator.userAgent;
ms_ie = /MSIE|Trident/.test(ua);
if ( ms_ie ) {
    //Do internet explorer exclusive behaviour here
}

There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)

You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.

UNAME := $(shell uname -m)

all:
    $(info Checking if custom header is needed)
    ifeq ($(UNAME), x86_64)
    ... do some things to build unistd_32.h
    endif

    @make -C $(KDIR) M=$(PWD) modules

So you want unistd_32.h built (maybe) before you invoke the second make, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:

ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif

all:
    @make -C $(KDIR) M=$(PWD) modules

unistd_32.h:
    ... do some things to build unistd_32.h

Now for building unistd_32.h:

F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
    $(info Copying custom header)
    $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else    
    F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
    ifeq ($(F2_EXISTS), 1)
        $(info Copying custom header)
        $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
    else
        $(error asm/unistd_32.h and asm-386/unistd.h does not exist)
    endif
endif

You are trying to build unistd.h from unistd_32.h; the only trick is that unistd_32.h could be in either of two places. The simplest way to clean this up is to use a vpath directive:

vpath unistd.h /usr/include/asm /usr/include/asm-i386

unistd_32.h: unistd.h
    sed -e 's/__NR_/__NR32_/g' $< > $@

You will have to use cookie to store the value across page refresh. You can use any one of the many javascript based cookie libraries to simplify the cookie access, like this one

If you want to support only html5 then you can think of Storage api like localStorage/sessionStorage

Ex: using localStorage and cookies library

var mode = getStoredValue('myPageMode');

function buttonClick(mode) {
    mode = mode;
    storeValue('myPageMode', mode);
}

function storeValue(key, value) {
    if (localStorage) {
        localStorage.setItem(key, value);
    } else {
        $.cookies.set(key, value);
    }
}

function getStoredValue(key) {
    if (localStorage) {
        return localStorage.getItem(key);
    } else {
        return $.cookies.get(key);
    }
}

I have use mkcert to create infinites *.dev.net subdomains & localhost with valid HTTPS/SSL certs (Windows 10 XAMPP & Linux Debian 10 Apache2)

I create the certs on Windows with mkcert v1.4.0 (execute CMD as Administrator):

mkcert -install
mkcert localhost "*.dev.net"

This create in Windows 10 this files (I will install it first in Windows 10 XAMPP)

localhost+1.pem
localhost+1-key.pem

Overwrite the XAMPP default certs:

copy "localhost+1.pem" C:\xampp\apache\conf\ssl.crt\server.crt
copy "localhost+1-key.pem"  C:\xampp\apache\conf\ssl.key\server.key

Now, in Apache2 for Debian 10, activate SSL & vhost_alias

a2enmod vhosts_alias
a2enmod ssl
a2ensite default-ssl
systemctl restart apache2

For vhost_alias add this Apache2 config:

nano /etc/apache2/sites-available/999-vhosts_alias.conf

With this content:

<VirtualHost *:80>
   UseCanonicalName Off
   ServerAlias *.dev.net
   VirtualDocumentRoot "/var/www/html/%0/"
</VirtualHost>

Add the site:

a2ensite 999-vhosts_alias

Copy the certs to /root/mkcert by SSH and let overwrite the Debian ones:

systemctl stop apache2

mv /etc/ssl/certs/ssl-cert-snakeoil.pem /etc/ssl/certs/ssl-cert-snakeoil.pem.bak
mv /etc/ssl/private/ssl-cert-snakeoil.key /etc/ssl/private/ssl-cert-snakeoil.key.bak

cp "localhost+1.pem" /etc/ssl/certs/ssl-cert-snakeoil.pem
cp "localhost+1-key.pem" /etc/ssl/private/ssl-cert-snakeoil.key

chown root:ssl-cert /etc/ssl/private/ssl-cert-snakeoil.key
chmod 640 /etc/ssl/private/ssl-cert-snakeoil.key

systemctl start apache2

Edit the SSL config

nano /etc/apache2/sites-enabled/default-ssl.conf

At the start edit the file with this content:

<IfModule mod_ssl.c>
    <VirtualHost *:443>

            UseCanonicalName Off
            ServerAlias *.dev.net
            ServerAdmin webmaster@localhost

            # DocumentRoot /var/www/html/
            VirtualDocumentRoot /var/www/html/%0/

...

Last restart:

systemctl restart apache2

NOTE: don´t forget to create the folders for your subdomains in /var/www/html/

/var/www/html/subdomain1.dev.net
/var/www/html/subdomain2.dev.net
/var/www/html/subdomain3.dev.net

If you intend to change A, B, C.... you see high above the columns, you can not. You can hide A, B, C...: Button Office(top left) Excel Options(bottom) Advanced(left) Right looking: Display options fot this worksheet: Select the worksheet(eg. Sheet3) Uncheck: Show column and row headers Ok

In JavaScript:

/[^\w_]/g

^ negation, i.e. select anything not in the following set

\w any word character (i.e. any alphanumeric character, plus underscore)

_ negate the underscore, as it's considered a 'word' character

Usage example - const nonAlphaNumericChars = /[^\w_]/g;

For correlations you can just use the corr function (statistics toolbox)

corr(A_1(:), A_2(:))

Note that you can also just use

corr(A_1, A_2)

But the linear indexing guarantees that your vectors don't need to be transposed.

While ireport does not officially support java8, there is a fairly simple way to make ireport (tested with ireport 5.1) work with Java 8. The problem is actually in netbeans. There is a very simple patch, assuming you don't care about the improved security in Java 8:

http://hg.netbeans.org/jet-main/diff/3238e03c676f/openide.util/src/org/openide/util/WeakListenerImpl.java

I didn't even use the exact netbeans source used by ireport. I just downloaded the latest WeakListenerImpl.java in full from the above repository, and compiled it in the ireport directory with platform9/lib/org-openide-util.jar in the compiler classpath

cd blah/blah/iReport-5.1.0
wget http://hg.netbeans.org/jet-main/raw-file/3238e03c676f/openide.util/src/org/openide/util/WeakListenerImpl.java
javac -d . -cp platform9/lib/org-openide-util.jar WeakListenerImpl.java
zip -r platform9/lib/org-openide-util.jar org

I am avoiding running eclipse just to edit jasper reports as long as I can. The netbeans based ireport is so much lighter weight. Running Eclipse is like using emacs.

int copt = 1;
int element = 0;
int[] array = { 1, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 5 };
for (int i = 0; i < array.Length; i++)
{
   for (int j = i + 1; j < array.Length - 1; j++)
   {
       if (array[i] == array[j])
       {
          element = array[i];
          copt++;
          break;
       }
   }
}

Console.WriteLine("the repeat element is {0} and it's appears {1} times ", element, copt);
Console.ReadKey();

// the output is the element is 3 and appears 9 times

My answer complements @maroun these are some ways to initialize an array:

Use an array

val numbers = arrayOf(1,2,3,4,5)

Use a strict array

val numbers = intArrayOf(1,2,3,4,5)

Mix types of matrices

val numbers = arrayOf(1,2,3.0,4f)

Nesting arrays

val numbersInitials = intArrayOf(1,2,3,4,5)
val numbers = arrayOf(numbersInitials, arrayOf(6,7,8,9,10))

Ability to start with dynamic code

val numbers = Array(5){ it*2}

Yes, you can. But if you have non-unique entries on your table, it will fail. Here is the how to add unique constraint on your table. If you're using PostgreSQL 9.x you can follow below instruction.

CREATE UNIQUE INDEX constraint_name ON table_name (columns);

You need to add else in your lambda function. Because you are telling what to do in case your condition(here x < 90) is met, but you are not telling what to do in case the condition is not met.

sample['PR'] = sample['PR'].apply(lambda x: 'NaN' if x < 90 else x) 

Please note that MVC 3 onwards the persistence behavior of TempData has changed, now the value in TempData is persisted until it is read, and not just for the next request.

The value of TempData persists until it is read or until the session times out. Persisting TempData in this way enables scenarios such as redirection, because the values in TempData are available beyond a single request. https://msdn.microsoft.com/en-in/library/dd394711%28v=vs.100%29.aspx

The database.yml is a file that is created with new rails applications in /config and defines the database configurations that your application will use in different environments. Read this for details.

Example database.yml:

development:
  adapter: sqlite3
  database: db/development.sqlite3
  pool: 5
  timeout: 5000

test:
  adapter: sqlite3
  database: db/test.sqlite3
  pool: 5
  timeout: 5000

production:
  adapter: mysql
  encoding: utf8
  database: your_db
  username: root
  password: your_pass
  socket: /tmp/mysql.sock
  host: your_db_ip     #defaults to 127.0.0.1
  port: 3306           

Example with no parameters:

delegate void NewEventHandler();
public event NewEventHandler OnEventHappens;

And from another class, you can subscribe to

otherClass.OnEventHappens += ExecuteThisFunctionWhenEventHappens;

And declare that function with no parameters.

try this, it works for me,

$('#myButton').click(function () {
    var redirectWindow = window.open('http://google.com', '_blank');
    $.ajax({
        type: 'POST',
        url: '/echo/json/',
        success: function (data) {
            redirectWindow.location;
        }
    });
});

The functions with an s take string parameters. The others take file streams.

i think token must include all the needed information encoded inside it, which makes authentication by validating the token and decoding the info https://www.oauth.com/oauth2-servers/access-tokens/self-encoded-access-tokens/

You want reorder(). Here is an example with dummy data

set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))

require("ggplot2")

p1 <- ggplot(df, aes(x = Category, y = Count)) +
         geom_bar(stat = "identity")

p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
         geom_bar(stat = "identity")

require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))

Giving:

Use reorder(Category, Count) to have Category ordered from low-high.

The more exact way applied to all Booostrap objects using standard classes only would be to not set top and bottom margins (as image can inherit these from parent), so I am always using:

.text-center .img-responsive {
    margin-left: auto;
    margin-right: auto;
}

I have also made a Gist for that, so if any changes will apply because of any bugs, update version will be always here: https://gist.github.com/jdrda/09a38bf152dd6a8aff4151c58679cc66

We use a script which checks if a running container is started with the latest image. We also use upstart init scripts for starting the docker image.

#!/usr/bin/env bash
set -e
BASE_IMAGE="registry"
REGISTRY="registry.hub.docker.com"
IMAGE="$REGISTRY/$BASE_IMAGE"
CID=$(docker ps | grep $IMAGE | awk '{print $1}')
docker pull $IMAGE

for im in $CID
do
    LATEST=`docker inspect --format "{{.Id}}" $IMAGE`
    RUNNING=`docker inspect --format "{{.Image}}" $im`
    NAME=`docker inspect --format '{{.Name}}' $im | sed "s/\///g"`
    echo "Latest:" $LATEST
    echo "Running:" $RUNNING
    if [ "$RUNNING" != "$LATEST" ];then
        echo "upgrading $NAME"
        stop docker-$NAME
        docker rm -f $NAME
        start docker-$NAME
    else
        echo "$NAME up to date"
    fi
done

And init looks like

docker run -t -i --name $NAME $im /bin/bash

I have found that creating a var to hold the WebElement and the call the sendKeys() works for me.

WebElement speedCurrentCell = driver.findElement(By.id("Speed_current"));
speedCurrentCell.sendKeys("1300");

Amazon changes the admin console from time to time, hence the previous answers above are irrelevant in 2020.

The way to get the secret access key (Oct.2020) is:

1. go to IAM console: https://console.aws.amazon.com/iam
2. click on "Users". (see image)
3. go to the user you need his access key.

As i see the answers above, I can assume my answer will become irrelevant in a year max :-)

It's just bcz your JS gets loaded before the HTML part and so it can't find that element. Just put your whole JS code inside a function which will be called when the window gets loaded.

You can also put your Javascript code below the html.

For Windows using ZBar

Pre-requisites:

• Install ZBar by either:
  • Install Chocolatey and choco install zbar
  • Or use Windows Installer for ZBar
• pip install pyzbar

To decode:

from PIL import Image
from pyzbar import pyzbar

img = Image.open('My-Image.jpg')
output = pyzbar.decode(img)
print(output)

Alternatively, you can also try using ZBarLight by setting it up as mentioned here:
https://pypi.org/project/zbarlight/

I have an implementation which allows the activity to be destroyed on a screen orientation change, but still destroys the dialog in the recreated activity successfully. I use ...NonConfigurationInstance to attach the background task to the recreated activity. The normal Android framework handles recreating the dialog itself, nothing is changed there.

I subclassed AsyncTask adding a field for the 'owning' activity, and a method to update this owner.

class MyBackgroundTask extends AsyncTask<...> {
  MyBackgroundTask (Activity a, ...) {
    super();
    this.ownerActivity = a;
  }

  public void attach(Activity a) {
    ownerActivity = a;
  }

  protected void onPostExecute(Integer result) {
    super.onPostExecute(result);
    ownerActivity.dismissDialog(DIALOG_PROGRESS);
  }

  ...
}

In my activity class I added a field backgroundTask referring to the 'owned' backgroundtask, and I update this field using onRetainNonConfigurationInstance and getLastNonConfigurationInstance.

class MyActivity extends Activity {
  public void onCreate(Bundle savedInstanceState) {
    ...
    if (getLastNonConfigurationInstance() != null) {
      backgroundTask = (MyBackgroundTask) getLastNonConfigurationInstance();
      backgroundTask.attach(this);
    }
  }

  void startBackgroundTask() {
    backgroundTask = new MyBackgroundTask(this, ...);
    showDialog(DIALOG_PROGRESS);
    backgroundTask.execute(...);
  }

  public Object onRetainNonConfigurationInstance() {
    if (backgroundTask != null && backgroundTask.getStatus() != Status.FINISHED)
      return backgroundTask;
    return null;
  }
  ...
}

Suggestions for further improvement:

• Clear the backgroundTask reference in the activity after the task is finished to release any memory or other resources associated with it.
• Clear the ownerActivity reference in the backgroundtask before the activity is destroyed in case it will not be recreated immediately.
• Create a BackgroundTask interface and/or collection to allow different types of tasks to run from the same owning activity.

Create a Name.bat file that has the following line in it.

Be sure not to overpower your processor. If you're running long scripts, your processor speed changes and script lines will override each other.

If any one's trying to fetch all headers that were passed then just simply use:

dict(request.headers)

it gives you all the headers in a dict from which you can actually do whatever ops you want to. In my use case I had to forward all headers to another API since the python API was a proxy

For completeness, here is a java-8 way of doing it

countMap.entrySet().stream().max((entry1, entry2) -> entry1.getValue() > entry2.getValue() ? 1 : -1).get().getKey();

or

Collections.max(countMap.entrySet(), (entry1, entry2) -> entry1.getValue() - entry2.getValue()).getKey();

or

Collections.max(countMap.entrySet(), Comparator.comparingInt(Map.Entry::getValue)).getKey();

Safest way :

static_cast<int>(reinterpret_cast<long>(void * your_variable));

long guarantees a pointer size on Linux on any machine. Windows has 32 bit long only on 64 bit as well. Therefore, you need to change it to long long instead of long in windows for 64 bits. So reinterpret_cast has casted it to long type and then static_cast safely casts long to int, if you are ready do truncte the data.

It can be done in 3 steps:

a) Count the number of lines in the file you want to edit:

 n=`cat myfile |wc -l`

b) Subtract from that number the number of lines to delete:

 x=$((n-3))

c) Tell sed to delete from that line number ($x) to the end:

 sed "$x,\$d" myfile

At first glance one really wants to use New-PSDrive supplying it credentials.

> New-PSDrive -Name P -PSProvider FileSystem -Root \\server\share -Credential domain\user

Fails!

New-PSDrive : Cannot retrieve the dynamic parameters for the cmdlet. Dynamic parameters for NewDrive cannot be retrieved for the 'FileSystem' provider. The provider does not support the use of credentials. Please perform the operation again without specifying credentials.

The documentation states that you can provide a PSCredential object but if you look closer the cmdlet does not support this yet. Maybe in the next version I guess.

Therefore you can either use net use or the WScript.Network object, calling the MapNetworkDrive function:

$net = new-object -ComObject WScript.Network
$net.MapNetworkDrive("u:", "\\server\share", $false, "domain\user", "password")

Edit for New-PSDrive in PowerShell 3.0

Apparently with newer versions of PowerShell, the New-PSDrive cmdlet works to map network shares with credentials!

New-PSDrive -Name P -PSProvider FileSystem -Root \\Server01\Public -Credential user\domain -Persist

• How can a developer use it?

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

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

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

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

Update: I have found a better/proper way to solve this problem using a BehaviorSubject or an Observable rather than an EventEmitter. Please see this answer: https://stackoverflow.com/a/35568924/215945

Also, the Angular docs now have a cookbook example that uses a Subject.

Original/outdated/wrong answer: again, don't use an EventEmitter in a service. That is an anti-pattern.

Using beta.1... NavService contains the EventEmiter. Component Navigation emits events via the service, and component ObservingComponent subscribes to the events.

nav.service.ts

import {EventEmitter} from 'angular2/core';
export class NavService {
  navchange: EventEmitter<number> = new EventEmitter();
  constructor() {}
  emitNavChangeEvent(number) {
    this.navchange.emit(number);
  }
  getNavChangeEmitter() {
    return this.navchange;
  }
}

components.ts

import {Component} from 'angular2/core';
import {NavService} from '../services/NavService';

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number = 0;
  subscription: any;
  constructor(private navService:NavService) {}
  ngOnInit() {
    this.subscription = this.navService.getNavChangeEmitter()
      .subscribe(item => this.selectedNavItem(item));
  }
  selectedNavItem(item: number) {
    this.item = item;
  }
  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
    <div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>
  `,
})
export class Navigation {
  item = 1;
  constructor(private navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this.navService.emitNavChangeEvent(item);
  }
}

Plunker

I suggest that you first start by reading BONUS' tutorial, And then reading Real World Haskell (online for free). Join the #Haskell IRC channel, on irc.freenode.com, and ask questions. These people are absolutely newbie friendly, and have helped me a lot over time. Also, right here on SO is a great place to get help with things you can't grasp! Try not to get discouraged, once it clicks, your mind will be blown.

BONUS' tutorial will prime you up, and get you ready for the thrill ride that Real World Haskell brings. I wish you luck!

TCPDF uses fopen() to save files. Any paths passed to TCPDF's Output() function should thus be an absolute path.

If you would like to save to a relative path, use e.g. the __DIR__ global constant (see this answer).

1. Copy and paste the form.
2. Rename the pasted form .cs to match the new form class name. This should auto rename other related files.
3. Open up .cs file. Change the class name and the name of the constructor(s) and destructor.
4. Open up .Designer.cs file and change the class name.

Extra Credit:

5. Consider abstracting common functionality from the form into common form or controls.

You can do this using the sysctl utility:

sysctl -n hw.ncpu

var string = 'Hello World!';

// Encode the String
var encodedString = btoa(string);

jsFiddle

with Node.js

Here is how you encode normal text to base64 in Node.js:

//Buffer() requires a number, array or string as the first parameter, and an optional encoding type as the second parameter. 
// Default is utf8, possible encoding types are ascii, utf8, ucs2, base64, binary, and hex
var b = new Buffer('JavaScript');
// If we don't use toString(), JavaScript assumes we want to convert the object to utf8.
// We can make it convert to other formats by passing the encoding type to toString().
var s = b.toString('base64');

And here is how you decode base64 encoded strings:

var b = new Buffer('SmF2YVNjcmlwdA==', 'base64')
var s = b.toString();

with Dojo.js

To encode an array of bytes using dojox.encoding.base64:

var str = dojox.encoding.base64.encode(myByteArray);

To decode a base64-encoded string:

var bytes = dojox.encoding.base64.decode(str)

bower install angular-base64

<script src="bower_components/angular-base64/angular-base64.js"></script>

angular
    .module('myApp', ['base64'])
    .controller('myController', [

    '$base64', '$scope', 
    function($base64, $scope) {

        $scope.encoded = $base64.encode('a string');
        $scope.decoded = $base64.decode('YSBzdHJpbmc=');
}]);

Try this:

insert into [table] ([data])
output inserted.id, inserted.data into table2
select [data] from [external_table]

UPDATE: Re:

Denis - this seems very close to what I want to do, but perhaps you could fix the following SQL statement for me? Basically the [data] in [table1] and the [data] in [table2] represent two different/distinct columns from [external_table]. The statement you posted above only works when you want the [data] columns to be the same.

INSERT INTO [table1] ([data]) 
OUTPUT [inserted].[id], [external_table].[col2] 
INTO [table2] SELECT [col1] 
FROM [external_table] 

It's impossible to output external columns in an insert statement, so I think you could do something like this

merge into [table1] as t
using [external_table] as s
on 1=0 --modify this predicate as necessary
when not matched then insert (data)
values (s.[col1])
output inserted.id, s.[col2] into [table2]
;

Apache Commons Lang has a NullArgumentException that does a number of the things discussed here: it extends IllegalArgumentException and its sole constructor takes the name of the argument which should have been non-null.

While I feel that throwing something like a NullArgumentException or IllegalArgumentException more accurately describes the exceptional circumstances, my colleagues and I have chosen to defer to Bloch's advice on the subject.

In order to use torchsummary type:

from torchsummary import summary

Install it first if you don't have it.

pip install torchsummary 

And then you can try it, but note from some reason it is not working unless I set model to cuda alexnet.cuda:

from torchsummary import summary
help(summary)
import torchvision.models as models
alexnet = models.alexnet(pretrained=False)
alexnet.cuda()
summary(alexnet, (3, 224, 224))
print(alexnet)

The summary must take the input size and batch size is set to -1 meaning any batch size we provide.

If we set summary(alexnet, (3, 224, 224), 32) this means use the bs=32.

summary(model, input_size, batch_size=-1, device='cuda')

Out:

Help on function summary in module torchsummary.torchsummary:

Since printArea is a jQuery plugin it is not included in jquery.d.ts.

You need to create a jquery.printArea.ts definition file.

If you create a complete definition file for the plugin you may want to submit it to DefinitelyTyped.

I recommend adding the following line after the export to PDF:

ThisWorkbook.Sheets("Sheet1").Select

(where eg. Sheet1 is the single sheet you want to be active afterwards)

Leaving multiple sheets in a selected state may cause problems executing some code. (eg. unprotect doesn't function properly when multiple sheets are actively selected.)

If you are using PHP, you can check previous url using php script rather than javascript. Here is the code:

echo $_SERVER['HTTP_REFERER'];

Hope it helps even out of relevance :)

If you want a quick and easy solution (and you have gulp installed).

In my gulpfile.js I run a simple copy paste task that puts any files I might need into ./public/modules/ directory.

gulp.task('modules', function() {
    sources = [
      './node_modules/prismjs/prism.js',
      './node_modules/prismjs/themes/prism-dark.css',
    ]
    gulp.src( sources ).pipe(gulp.dest('./public/modules/'));
});

gulp.task('copy-modules', ['modules']);

The downside to this is that it isn't automated. However, if all you need is a few scripts and styles copied over (and kept in a list), this should do the job.

Let me add my 5 cents.

Frame is used by the view's parent view to place it inside the parent view.

Bounds is used by the view itself to place it's own content (like a scroll view does while scrolling). See also clipsToBounds. Bounds also can be used to zoom in/out content of the view.

Analogy:
Frame ~ TV screen
Bounds ~ Camera (zoom, move, rotate)

you call function on page load time but not call on button event, you will need to call function onclick event, you may add event inline element style or event bining

 function Choice(elem) {_x000D_
   var box = document.getElementById("box");_x000D_
   if (elem.id == "no") {_x000D_
     box.style.backgroundColor = "red";_x000D_
   } else if (elem.id == "yes") {_x000D_
     box.style.backgroundColor = "green";_x000D_
   } else {_x000D_
     box.style.backgroundColor = "purple";_x000D_
   };_x000D_
 };

<div id="box">dd</div>_x000D_
<button id="yes" onclick="Choice(this);">yes</button>_x000D_
<button id="no" onclick="Choice(this);">no</button>_x000D_
<button id="other" onclick="Choice(this);">other</button>

or event binding,

window.onload = function() {_x000D_
  var box = document.getElementById("box");_x000D_
  document.getElementById("yes").onclick = function() {_x000D_
    box.style.backgroundColor = "red";_x000D_
  }_x000D_
  document.getElementById("no").onclick = function() {_x000D_
    box.style.backgroundColor = "green";_x000D_
  }_x000D_
}

<div id="box">dd</div>_x000D_
<button id="yes">yes</button>_x000D_
<button id="no">no</button>

Example in C:

// function
int square( int n ) {
   return n * n;
}

// procedure
void display( int n ) {
   printf( "The value is %d", n );
}

Although you should note that the C Standard doesn't talk about procedures, only functions.

This three lines of code can remove the duplicated element from ArrayList or any collection.

List<Entity> entities = repository.findByUserId(userId);

Set<Entity> s = new LinkedHashSet<Entity>(entities);
entities.clear();
entities.addAll(s);

I had this problem today as well. I only got the problem inside the virtual env.

The solution for me was deactivating the virtual env, deleting and then uninstalling virtualenv with pip and reinstalling it. After that I created a new virtual env for my project, then pip worked fine both inside the virtual environment as in the normal environment.

That particular phrasing is by James Iry, from his highly entertaining Brief, Incomplete and Mostly Wrong History of Programming Languages, in which he fictionally attributes it to Philip Wadler.

The original quote is from Saunders Mac Lane in Categories for the Working Mathematician, one of the foundational texts of Category Theory. Here it is in context, which is probably the best place to learn exactly what it means.

But, I'll take a stab. The original sentence is this:

All told, a monad in X is just a monoid in the category of endofunctors of X, with product × replaced by composition of endofunctors and unit set by the identity endofunctor.

X here is a category. Endofunctors are functors from a category to itself (which is usually all Functors as far as functional programmers are concerned, since they're mostly dealing with just one category; the category of types - but I digress). But you could imagine another category which is the category of "endofunctors on X". This is a category in which the objects are endofunctors and the morphisms are natural transformations.

And of those endofunctors, some of them might be monads. Which ones are monads? Exactly the ones which are monoidal in a particular sense. Instead of spelling out the exact mapping from monads to monoids (since Mac Lane does that far better than I could hope to), I'll just put their respective definitions side by side and let you compare:

A monoid is...

• A set, S
• An operation, • : S × S ? S
• An element of S, e : 1 ? S

...satisfying these laws:

• (a • b) • c = a • (b • c), for all a, b and c in S
• e • a = a • e = a, for all a in S

A monad is...

• An endofunctor, T : X ? X (in Haskell, a type constructor of kind * -> * with a Functor instance)
• A natural transformation, µ : T × T ? T, where × means functor composition (µ is known as join in Haskell)
• A natural transformation, ? : I ? T, where I is the identity endofunctor on X (? is known as return in Haskell)

...satisfying these laws:

• µ ° Tµ = µ ° µT
• µ ° T? = µ ° ?T = 1 (the identity natural transformation)

With a bit of squinting you might be able to see that both of these definitions are instances of the same abstract concept.

The last inserted record can be queried using this assuming you have the "id" as the primary key:

SELECT timestamp,value,card FROM my_table WHERE id=(select max(id) from my_table)

Assuming every new row inserted will use the highest integer value for the table's id.

You should use glob.

glob('*.xml')

More about using glob and advanced filtering:

http://domexception.blogspot.fi/2013/08/php-using-functional-programming-for.html

This works in latest Chrome, FireFox and Edge, but not IE11:

document.evaluate('//option[text()="Yahoo"]', document).iterateNext().selected = 'selected';

And if you want to ignore spaces around the title:

document.evaluate('//option[normalize-space(text())="Yahoo"]', document).iterateNext().selected = 'selected'

If you want a (almost) one-liner:

from collections import deque

d = {}
deque((d.setdefault(year, []).append(value) for year, value in source_of_data), maxlen=0)

Using dict.setdefault, you can encapsulate the idea of "check if the key already exists and make a new list if not" into a single call. This allows you to write a generator expression which is consumed by deque as efficiently as possible since the queue length is set to zero. The deque will be discarded immediately and the result will be in d.

This is something I just did for fun. I don't recommend using it. There is a time and a place to consume arbitrary iterables through a deque, and this is definitely not it.

Since g++ 4.7 it does understand the new C++11 override keyword:

class child : public parent {
    public:
      // force handle_event to override a existing function in parent
      // error out if the function with the correct signature does not exist
      void handle_event(int something) override;
};

Numpy will be suitable for most people, but you can also do matrices in Sympy

Try running these commands at http://live.sympy.org/

M = Matrix([[1, 3], [-2, 3]])
M
M**-1

For fun, try M**(1/2)

I often ended up doing things like this. Therefore I tried to write a simple function that 'snips' out the unwanted elements in an easy way. This turns matlab logic a bit upside down, but looks good:

b = snip(a,'0')

It also works with all other 'x', nan or whatever elements.

I’ve been struggling with this for a while now. Dycey’s solution is correct in that specifying the src multiple times outputs the same thing in your css file. However, this seems to break in OSX Firefox 23 (probably other versions too, but I don’t have time to test).

The cross-browser @font-face solution from Font Squirrel looks like this:

@font-face {
    font-family: 'fontname';
    src: url('fontname.eot');
    src: url('fontname.eot?#iefix') format('embedded-opentype'),
         url('fontname.woff') format('woff'),
         url('fontname.ttf') format('truetype'),
         url('fontname.svg#fontname') format('svg');
    font-weight: normal;
    font-style: normal;
}

To produce the src property with the comma-separated values, you need to write all of the values on one line, since line-breaks are not supported in Sass. To produce the above declaration, you would write the following Sass:

@font-face
  font-family: 'fontname'
  src: url('fontname.eot')
  src: url('fontname.eot?#iefix') format('embedded-opentype'), url('fontname.woff') format('woff'), url('fontname.ttf') format('truetype'), url('fontname.svg#fontname') format('svg')
  font-weight: normal
  font-style: normal

I think it seems silly to write out the path a bunch of times, and I don’t like overly long lines in my code, so I worked around it by writing this mixin:

=font-face($family, $path, $svg, $weight: normal, $style: normal)
  @font-face
    font-family: $family
    src: url('#{$path}.eot')
    src: url('#{$path}.eot?#iefix') format('embedded-opentype'), url('#{$path}.woff') format('woff'), url('#{$path}.ttf') format('truetype'), url('#{$path}.svg##{$svg}') format('svg')
    font-weight: $weight
    font-style: $style

Usage: For example, I can use the previous mixin to setup up the Frutiger Light font like this:

+font-face('frutigerlight', '../fonts/frutilig-webfont', 'frutigerlight')

Environment variables are accessed through os.environ

import os
print(os.environ['HOME'])

Or you can see a list of all the environment variables using:

os.environ

As sometimes you might need to see a complete list!

# using get will return `None` if a key is not present rather than raise a `KeyError`
print(os.environ.get('KEY_THAT_MIGHT_EXIST'))

# os.getenv is equivalent, and can also give a default value instead of `None`
print(os.getenv('KEY_THAT_MIGHT_EXIST', default_value))

Python default installation on Windows is C:\Python. If you want to find out while running python you can do:

import sys
print(sys.prefix)

I was plagued by this error message despite using async: true. It turns out the actual problem was using the success method. I changed this to done and warning is gone.

success: function(response) { ... }

replaced with:

done: function(response) { ... }
