Another way of doing it:

df.select(f.max(f.col("A")).alias("MAX")).limit(1).collect()[0].MAX

On my data, I got this benchmarks:

df.select(f.max(f.col("A")).alias("MAX")).limit(1).collect()[0].MAX
CPU times: user 2.31 ms, sys: 3.31 ms, total: 5.62 ms
Wall time: 3.7 s

df.select("A").rdd.max()[0]
CPU times: user 23.2 ms, sys: 13.9 ms, total: 37.1 ms
Wall time: 10.3 s

df.agg({"A": "max"}).collect()[0][0]
CPU times: user 0 ns, sys: 4.77 ms, total: 4.77 ms
Wall time: 3.75 s

All of them give the same answer

Zip Arrays of same length:

Using Array.prototype.map()

const zip = (a, b) => a.map((k, i) => [k, b[i]]);

console.log(zip([1,2,3], ["a","b","c"]));
// [[1, "a"], [2, "b"], [3, "c"]]

Zip Arrays of different length:

Using Array.from()

const zip = (a, b) => Array.from(Array(Math.max(b.length, a.length)), (_, i) => [a[i], b[i]]);

console.log( zip([1,2,3], ["a","b","c","d"]) );
// [[1, "a"], [2, "b"], [3, "c"], [undefined, "d"]]

Using Array.prototype.fill() and Array.prototype.map()

const zip = (a, b) => Array(Math.max(b.length, a.length)).fill().map((_,i) => [a[i], b[i]]);

console.log(zip([1,2,3], ["a","b","c","d"]));
// [[1, "a"], [2, "b"], [3, "c"], [undefined, 'd']]

Chrome is preflighting the request to look for CORS headers. If the request is acceptable, it will then send the real request. If you're doing this cross-domain, you will simply have to deal with it or else find a way to make the request non-cross-domain. This is why the jQuery bug was closed as won't-fix. This is by design.

Unlike simple requests (discussed above), "preflighted" requests first send an HTTP request by the OPTIONS method to the resource on the other domain, in order to determine whether the actual request is safe to send. Cross-site requests are preflighted like this since they may have implications to user data. In particular, a request is preflighted if:

• It uses methods other than GET, HEAD or POST. Also, if POST is used to send request data with a Content-Type other than application/x-www-form-urlencoded, multipart/form-data, or text/plain, e.g. if the POST request sends an XML payload to the server using application/xml or text/xml, then the request is preflighted.
• It sets custom headers in the request (e.g. the request uses a header such as X-PINGOTHER)

Per Arvand:
Eclipse: Simply type android.R.layout.simple_list_item_1 somewhere in code, hold Ctrl, hover over simple_list_item_1, and from the dropdown that appears select Open declaration in layout/simple_list_item_1.xml. It'll direct you to the contents of the XML.

From there, if you then hover over the resulting simple_list_item_1.xml tab in the Editor, you'll see the file is located at C:\Data\applications\Android\android-sdk\platforms\android-19\data\res\layout\simple_list_item_1.xml (or equivalent location for your installation).

Below is a positive lookbehind JavaScript alternative showing how to capture the last name of people with 'Michael' as their first name.

1) Given this text:

const exampleText = "Michael, how are you? - Cool, how is John Williamns and Michael Jordan? I don't know but Michael Johnson is fine. Michael do you still score points with LeBron James, Michael Green Miller and Michael Wood?";

get an array of last names of people named Michael. The result should be: ["Jordan","Johnson","Green","Wood"]

2) Solution:

function getMichaelLastName2(text) {
  return text
    .match(/(?:Michael )([A-Z][a-z]+)/g)
    .map(person => person.slice(person.indexOf(' ')+1));
}

// or even
    .map(person => person.slice(8)); // since we know the length of "Michael "

3) Check solution

console.log(JSON.stringify(    getMichaelLastName(exampleText)    ));
// ["Jordan","Johnson","Green","Wood"]

Demo here: http://codepen.io/PiotrBerebecki/pen/GjwRoo

You can also try it out by running the snippet below.

const inputText = "Michael, how are you? - Cool, how is John Williamns and Michael Jordan? I don't know but Michael Johnson is fine. Michael do you still score points with LeBron James, Michael Green Miller and Michael Wood?";_x000D_

    .map(person => person.slice(8));_x000D_

You can use PropertyConfigurator to load your log4j.properties wherever it is located in the disk.

Example:

Logger logger = Logger.getLogger(this.getClass());
String log4JPropertyFile = "C:/this/is/my/config/path/log4j.properties";
Properties p = new Properties();

try {
    p.load(new FileInputStream(log4JPropertyFile));
    PropertyConfigurator.configure(p);
    logger.info("Wow! I'm configured!");
} catch (IOException e) {
    //DAMN! I'm not....

}

If you have an XML Log4J configuration, use DOMConfigurator instead.

Once I found an xsd link on the top of the wsdl. Like this wsdl example from the web, you can see a link xsd1. The server has to be running to see it.

<?xml version="1.0"?>

             targetNamespace="http://example.com/stockquote.wsdl"
             xmlns:tns="http://example.com/stockquote.wsdl"
             xmlns:xsd1="http://example.com/stockquote.xsd"
             xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
             xmlns="http://schemas.xmlsoap.org/wsdl/">

I know this has several answers, but none of these really helped me. I found [this article][1] which explains why my sticky wasn't operating as expected.

Basically, you cannot use position: sticky; on <thead> or <tr> elements. However, they can be used on <th>.

The minimum code I needed to make it work is as follows:

table {
  text-align: left;
  position: relative;
}

th {
  background: white;
  position: sticky;
  top: 0;
}

With the table set to relative the <th> can be set to sticky, with the top at 0 [1]: https://css-tricks.com/position-sticky-and-table-headers/

NOTE: It's necessary to wrap the table with a div with max-height:

<div id="managerTable" >
...
</div>

where:

#managerTable {
    max-height: 500px;
    overflow: auto;
}

For anyone completely new to Qt Creator like me, you can modify your project's .pro file from within Qt Creator:

Just double-click on "your project name".pro in the Projects window and add the include path at the bottom of the .pro file like I've done.

You should be able to compare them directly.

var date = moment("2013-03-24")
var now = moment();

if (now > date) {
   // date is past
} else {
   // date is future
}

$(document).ready(function() {_x000D_
  _x000D_
  $('.compare').click(function(e) {_x000D_
  _x000D_
    var date = $('#date').val();_x000D_
  _x000D_
    var now = moment();_x000D_
    var then = moment(date);_x000D_
  _x000D_
    if (now > then) {_x000D_
      $('.result').text('Date is past');_x000D_
    } else {_x000D_
      $('.result').text('Date is future');_x000D_

DECLARE @table1 TABLE (
    idx int identity(1,1),
    col1 int )

DECLARE @counter int

SET @counter = 1

WHILE(@counter < SELECT MAX(idx) FROM @table1)
BEGIN
    DECLARE @colVar INT

    SELECT @colVar = col1 FROM @table1 WHERE idx = @counter

    -- Do your work here

    SET @counter = @counter + 1
END

Believe it or not, this is actually more efficient and performant than using a cursor.

If you want the view to be read only after granting the read permission you can use the ALGORITHM = TEMPTABLE in you view DDL definition.

If IsNull({TABLE.FIELD1}) then "NULL" +',' + {TABLE.FIELD2} else {TABLE.FIELD1} + ', ' + {TABLE.FIELD2}

Here I put NULL as string to display the string value NULL in place of the null value in the data field. Hope you understand.

To SSH connectivity to AWS EC2 instance, You don't need to convert the .PEM file to PPK file even on windows machine, Simple SSH using 'git bash' tool. No need to download and convert these softwares - Hope this will save your time of downloading and converting keys and get you more time on EC2 things.

The get_ddl procedure for a PACKAGE will return both spec AND body, so it will be better to change the query on the all_objects so the package bodies are not returned on the select.

So far I changed the query to this:

SELECT DBMS_METADATA.GET_DDL(REPLACE(object_type, ' ', '_'), object_name, owner)
FROM all_OBJECTS
WHERE (OWNER = 'OWNER1')
and object_type not like '%PARTITION'
and object_type not like '%BODY'
order by object_type, object_name;

Although other changes might be needed depending on the object types you are getting...

Perhaps str.to_s.downcase == 'true' for completeness. Then nothing can crash even if str is nil or 0.

As always, I recommend reading this article about date and time in Java so that you understand it.

The basic idea is that 'under the hood' everything is done in UTC milliseconds since the epoch. This means it is easiest if you operate without using time zones at all, with the exception of String formatting for the user.

Therefore I would skip most of the steps you have suggested.

1. Set the time on an object (Date, Calendar etc).
2. Set the time zone on a formatter object.
3. Return a String from the formatter.

Alternatively, you can use Joda time. I have heard it is a much more intuitive datetime API.

Use class.name. This also works with function.name.

class TestA {}
console.log(TestA.name); // "TestA"

function TestB() {}
console.log(TestB.name); // "TestB"

Just to clear some things up here. The answer that was accepted does not do the same as PHP in_array.

To do the same as PHP in_array use following expression:

{% if myVar in myArray %}

If you want to negate this you should use this:

{% if myVar not in myArray %}

I've seen your question and answers, and made a new responsive and flexible multi items carousel Gist. you can see it here:

Make sure to learn from the padding oracle asp.net vulnerability that just happened (you applied the patch, right? ...) and use protected sections to encrypt the machine key and any other sensitive configuration.

An alternative option is to set it in the machine level web.config, so its not even in the web site folder.

To generate it do it just like the linked article in David's answer.

You can set your activity to use a specific volume. In your activity, use one of the following:

this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
this.setVolumeControlStream(AudioManager.STREAM_RING);  
this.setVolumeControlStream(AudioManager.STREAM_ALARM);  
this.setVolumeControlStream(AudioManager.STREAM_NOTIFICATION);  
this.setVolumeControlStream(AudioManager.STREAM_SYSTEM);  
this.setVolumeControlStream(AudioManager.STREAM_VOICECALL); 

1. If key class is your's make sure the hashCode() and equals() methods implemented.
2. Basically the access to HashMap should be O(1) but with wrong hashCode method implementation it's become O(n), because value with same hash key will stored as Linked list.

Try this...

var key = words.Where(x => x.IsKey == true);

# 'A Generic Makefile for Building Multiple main() Targets in $PWD'
# Author:  Robert A. Nader (2012)
# Email: naderra at some g
# Web: xiberix
############################################################################
#  The purpose of this makefile is to compile to executable all C source
#  files in CWD, where each .c file has a main() function, and each object
#  links with a common LDFLAG.
#
#  This makefile should suffice for simple projects that require building
#  similar executable targets.  For example, if your CWD build requires
#  exclusively this pattern:
#
#  cc -c $(CFLAGS) main_01.c
#  cc main_01.o $(LDFLAGS) -o main_01
#
#  cc -c $(CFLAGS) main_2..c
#  cc main_02.o $(LDFLAGS) -o main_02
#
#  etc, ... a common case when compiling the programs of some chapter,
#  then you may be interested in using this makefile.
#
#  What YOU do:
#
#  Set PRG_SUFFIX_FLAG below to either 0 or 1 to enable or disable
#  the generation of a .exe suffix on executables
#
#  Set CFLAGS and LDFLAGS according to your needs.
#
#  What this makefile does automagically:
#
#  Sets SRC to a list of *.c files in PWD using wildcard.
#  Sets PRGS BINS and OBJS using pattern substitution.
#  Compiles each individual .c to .o object file.
#  Links each individual .o to its corresponding executable.

I made a one-liner out of @JohnL's solution:

$MyInvocation.MyCommand.Path | Split-Path | Push-Location

objectname.newProperty = value;

Follow this:

1. Create a bin folder in any directory(to be used in step 3).

2. Download winutils.exe and place it in the bin directory.

3. Now add System.setProperty("hadoop.home.dir", "PATH/TO/THE/DIR"); in your code.

Simple use this to strip the text :

echo strlen($string) >= 500 ? 
substr($string, 0, 490) . ' <a href="link/to/the/entire/text.htm">[Read more]</a>' : 
$string;

Edit and finally :

function split_words($string, $nb_caracs, $separator){
    $string = strip_tags(html_entity_decode($string));
    if( strlen($string) <= $nb_caracs ){
        $final_string = $string;
    } else {
        $final_string = "";
        $words = explode(" ", $string);
        foreach( $words as $value ){
            if( strlen($final_string . " " . $value) < $nb_caracs ){
                if( !empty($final_string) ) $final_string .= " ";
                $final_string .= $value;
            } else {
                break;
            }
        }
        $final_string .= $separator;
    }
    return $final_string;

Here separator is the href link to read more ;)

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

Objective-C

You can use (see NSString Class Reference)

- (id)initWithData:(NSData *)data encoding:(NSStringEncoding)encoding

Example:

NSString *myString = [[NSString alloc] initWithData:myData encoding:NSUTF8StringEncoding];

Remark: Please notice the NSData value must be valid for the encoding specified (UTF-8 in the example above), otherwise nil will be returned:

Returns nil if the initialization fails for some reason (for example if data does not represent valid data for encoding).

Prior Swift 3.0

String(data: yourData, encoding: NSUTF8StringEncoding)

Swift 3.0 Onwards

String(data: yourData, encoding: .utf8)

See String#init(data:encoding:) Reference

scp -r C:/site user@server_ip:path

path is the place, where site will be copied into the remote server

EDIT: As I said in my comment, try pscp, as you want to use scp using PuTTY.

The other option is WinSCP

SplFileObject is useful when it comes to dealing with large files.

function parse_file($filename)
{
    try {
        $file = new SplFileObject($filename);
    } catch (LogicException $exception) {
        die('SplFileObject : '.$exception->getMessage());
    }
    while ($file->valid()) {
        $line = $file->fgets();
        //do something with $line
    }

    //don't forget to free the file handle.
    $file = null;
}

pip install pyyaml

If you don't have pip, run easy_install pip to install pip, which is the go-to package installer - Why use pip over easy_install?. If you prefer to stick with easy_install, then easy_install pyyaml

In Eclipse , rightclick on your application

Run As -> Run configurations -> select your server from type filter text box

Then in Classpath under Bootstrap Entries add your classes12.jar File and Click on Apply.
Now, run the file...... This worked for me !!

You've already done it correctly by using a DateTime parameter with the value from the DateTime, so it should already work. Forget about ToString() - since that isn't used here.

If there is a difference, it is most likely to do with different precision between the two environments; maybe choose a rounding (seconds, maybe?) and use that. Also keep in mind UTC/local/unknown (the DB has no concept of the "kind" of date; .NET does).

I have a table and the date-times in it are in the format: 2011-07-01 15:17:33.357

Note that datetimes in the database aren't in any such format; that is just your query-client showing you white lies. It is stored as a number (and even that is an implementation detail), because humans have this odd tendency not to realise that the date you've shown is the same as 40723.6371916281. Stupid humans. By treating it simply as a "datetime" throughout, you shouldn't get any problems.

In reply to James Craig Burley's answer. In order to make a clean and re-usable design, one might choose for a more object oriented approach. This way methods can be safely bound to the types of the specified map. To me this approach feels cleaner and organized.

Example:

package main

import (
    "fmt"
    "sort"
)

type myIntMap map[int]string

func (m myIntMap) sort() (index []int) {
    for k, _ := range m {
        index = append(index, k)
    }
    sort.Ints(index)
    return
}

func main() {
    m := myIntMap{
        1:  "one",
        11: "eleven",
        3:  "three",
    }
    for _, k := range m.sort() {
        fmt.Println(m[k])
    }
}

Extended playground example with multiple map types.

Important note

In all cases, the map and the sorted slice are decoupled from the moment the for loop over the map range is finished. Meaning that, if the map gets modified after the sorting logic, but before you use it, you can get into trouble. (Not thread / Go routine safe). If there is a change of parallel Map write access, you'll need to use a mutex around the writes and the sorted for loop.

mutex.Lock()
for _, k := range m.sort() {
    fmt.Println(m[k])
}
mutex.Unlock()

I think this is what you want:

/grand/parent/child[@id="#grand"]

public static string StripTags2(string html) { return html.Replace("<", "<").Replace(">", ">"); }

By this you escape all "<" and ">" in a string. Is this what you want?

Add your controllers in your folders:

controllers\
---- folder1
---- folder2

Create your route not specifying the folder:

Route::get('/product/dashboard', 'MakeDashboardController@showDashboard');

Run

composer dump-autoload

And try again

"AndroidManifest" file not changed for me and i change package name manually.

Just check JSON option from the drop down next to binary; when you click raw. This should do

You might not need jQuery for this task. FormData is a perfect solution for this.

Here is the code that use FormData to collect input values, and use dot-prop to transform the values into nested objects.

My error was on a variable declaration line with a multi-line extension. I have a trailing space after the "\" which made that an invalid line continuation.

HashMap<String, ArrayList<Item>> items = new HashMap<String, ArrayList<Item>>();

    if(itemsList == null) {
         itemsList = new ArrayList<Item>();
         itemsList.add(myItem);

=Sum(C:C)-Sum(C1:C5)

Sum everything then remove the sum of the values in the cells you don't want, no Volatile Offset's, Indirect's, or Array's needed.

Just for fun if you don't like that method you could also use:

=SUM($C$6:INDEX($C:$C,MATCH(9.99999999999999E+307,$C:$C))

The above formula will Sum only from C6 through the last cell in C:C where a match of a number is found. This is also non-volatile, but I believe more costly and sloppy. Just added it in case you'd prefer this anyways.

If you would like to do function like CountA for text using the last text value in a column you could use.

=COUNTIF(C6:INDEX($C:$C,MATCH(REPT("Z",255),$C:$C)),"T")

you could also use other combinations like:

=Sum($C$6:$C$65536) 

or

=CountIF($C$6:$C$65536,"T") 

The above would do what you ask in Excel 2003 and lower

=Sum($C$6:$C$1048576) 

or

=CountIF($C$6:$C$1048576,"T")

Would both work for Excel 2007+

All above functions would simply ignore all the blank values under the last value.

Just use CSS transitions instead of animations.

A {
    color: #999;
    transition: color 1s ease-in-out;
}

A:hover {
    color: #000;
}

You should not try to do this directly. Design your tasks to work with a CancellationToken, and cancel them this way.

In addition, I would recommend changing your main thread to function via a CancellationToken as well. Calling Thread.Abort() is a bad idea - it can lead to various problems that are very difficult to diagnose. Instead, that thread can use the same Cancellation that your tasks use - and the same CancellationTokenSource can be used to trigger the cancellation of all of your tasks and your main thread.

This will lead to a far simpler, and safer, design.

Javascript has built in trim:

str.trim()

It doesn't work in IE8. If you have to support older browsers, use Tuxmentat's or Paul's answer.

This could be done simpler:

<base href="${pageContext.request.contextPath}/"/>

All URL will be formed without unnecessary domain:port but with application context.

    private void BindDataBInfo()
    {
        System.Web.HttpBrowserCapabilities browser = Request.Browser;
        Literal1.Text = "<table border=\"1\" cellspacing=\"3\" cellpadding=\"2\">";
        foreach (string key in browser.Capabilities.Keys)
        {
            Literal1.Text += "<tr><td>" + key + "</td><td>" + browser[key] + "</tr>";
        }
        Literal1.Text += "</table>";
        browser = null;
    }

Try:

RENAME database1 TO database2;

Add a listener to the underlying Document, which is automatically created for you.

// Listen for changes in the text
textField.getDocument().addDocumentListener(new DocumentListener() {
  public void changedUpdate(DocumentEvent e) {
    warn();
  }
  public void removeUpdate(DocumentEvent e) {
    warn();
  }
  public void insertUpdate(DocumentEvent e) {
    warn();
  }

  public void warn() {
     if (Integer.parseInt(textField.getText())<=0){
       JOptionPane.showMessageDialog(null,
          "Error: Please enter number bigger than 0", "Error Message",
          JOptionPane.ERROR_MESSAGE);
     }
  }
});

If you are using Mac OS X, I would recommend you get Tower, it's a wonderful program that has made dealing with Git a pleasure for me. I now longer have to remember terminal commands and it offers a great GUI to view, track and solve differences in files.

And no, I'm not affiliated with them, I just use their software and really like it.

Add a certificate validation handler. Returning true will allow ignoring the validation error:

ServicePointManager
    .ServerCertificateValidationCallback += 
    (sender, cert, chain, sslPolicyErrors) => true;

I found this on React's Github issues: Works like a charm (v15.6.2)

Here is how I implemented to a Text input:

changeInputValue = newValue => {

    const e = new Event('input', { bubbles: true })
    const input = document.querySelector('input[name=' + this.props.name + ']')
    console.log('input', input)
    this.setNativeValue(input, newValue)
    input.dispatchEvent(e)
  }

  setNativeValue (element, value) {
    const valueSetter = Object.getOwnPropertyDescriptor(element, 'value').set
    const prototype = Object.getPrototypeOf(element)
    const prototypeValueSetter = Object.getOwnPropertyDescriptor(
      prototype,
      'value'
    ).set

    if (valueSetter && valueSetter !== prototypeValueSetter) {
      prototypeValueSetter.call(element, value)
    } else {
      valueSetter.call(element, value)
    }
  }

This is a late answer. Starting from SQLIte 3.24.0, released on June 4, 2018, there is finally a support for UPSERT clause following PostgreSQL syntax.

INSERT INTO players (user_name, age)
  VALUES('steven', 32) 
  ON CONFLICT(user_name) 
  DO UPDATE SET age=excluded.age;

Note: For those having to use a version of SQLite earlier than 3.24.0, please reference this answer below (posted by me, @MarqueIV).

However if you do have the option to upgrade, you are strongly encouraged to do so as unlike my solution, the one posted here achieves the desired behavior in a single statement. Plus you get all the other features, improvements and bug fixes that usually come with a more recent release.

My hour of pain was due to defining MIME types in the web.config. I needed this for the development server but local IIS hated it because it duplicated MIME types... once I removed these from the web.config the problem with js, css, and images not loading went away.

Since you are always initialising self.listMyData to an empty list in clkFindMost your code will always lead to this error* because after that both unique_names and frequencies are empty iterables, so fix this.

Another thing is that since you're iterating over a set in that method then calculating frequency makes no sense as set contain only unique items, so frequency of each item is always going to be 1.

Lastly dict.get is a method not a list or dictionary so you can't use [] with it:

Correct way is:

if frequencies.get(name):

And Pythonic way is:

if name in frequencies:

The Pythonic way to get the frequency of items is to use collections.Counter:

from collections import Counter   #Add this at the top of file.

def clkFindMost(self, parent):

        #self.listMyData = []   
        if self.listMyData:
           frequencies = Counter(self.listMyData)
           self.txtResults.Value = max(frequencies, key=frequencies.get)
        else:
           self.txtResults.Value = '' 

max() and min() throw such error when an empty iterable is passed to them. You can check the length of v before calling max() on it.

>>> lst = []
>>> max(lst)

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    max(lst)
ValueError: max() arg is an empty sequence
>>> if lst:
    mx = max(lst)
else:
    #Handle this here

If you are using it with an iterator then you need to consume the iterator first before calling max() on it because boolean value of iterator is always True, so we can't use if on them directly:

>>> it = iter([])
>>> bool(it)
True
>>> lst = list(it)
>>> if lst:
       mx = max(lst)
    else:
      #Handle this here   

Good news is starting from Python 3.4 you will be able to specify an optional return value for min() and max() in case of empty iterable.

I found an event OnError in confluent Kafka:

consumer.OnError += Consumer_OnError;

 private void Consumer_OnError(object sender, Error e)
    {
        Debug.Log("connection error: "+ e.Reason);
        ConsumerConnectionError(e);
    }

And its documentation in code:

    //
    // Summary:
    //     Raised on critical errors, e.g. connection failures or all brokers down. Note
    //     that the client will try to automatically recover from errors - these errors
    //     should be seen as informational rather than catastrophic
    //
    // Remarks:
    //     Executes on the same thread as every other Consumer event handler (except OnLog
    //     which may be called from an arbitrary thread).
    public event EventHandler<Error> OnError;

In C++11

I would use general algorithms like for_each to avoid searching for the right type of iterator and lambda expression to avoid extra named functions/objects.

The short "pretty" example for your particular case (assuming polygon is a vector of integers):

for_each(polygon.begin(), polygon.end(), [&sum](int i){ sum += i; });

tested on: http://ideone.com/i6Ethd

Dont' forget to include: algorithm and, of course, vector :)

Microsoft has actually also a nice example on this:
source: http://msdn.microsoft.com/en-us/library/dd293608.aspx

#include <algorithm>
#include <iostream>
#include <vector>
using namespace std;

int main() 
{
   // Create a vector object that contains 10 elements.
   vector<int> v;
   for (int i = 1; i < 10; ++i) {
      v.push_back(i);
   }

   // Count the number of even numbers in the vector by 
   // using the for_each function and a lambda.
   int evenCount = 0;
   for_each(v.begin(), v.end(), [&evenCount] (int n) {
      cout << n;
      if (n % 2 == 0) {
         cout << " is even " << endl;
         ++evenCount;
      } else {
         cout << " is odd " << endl;
      }
   });

   // Print the count of even numbers to the console.
   cout << "There are " << evenCount 
        << " even numbers in the vector." << endl;
}

Create a .htaccess file in the images folder and add this

<IfModule mod_rewrite.c>
RewriteEngine On
# directory browsing
Options All +Indexes
</IfModule>

you can put this Options All -Indexes in the project file .htaccess ,file to deny direct access to other folders.

This does what you want

Here's @Daniel Vérité's function with progress reporting functionality. It reports progress in three ways:

1. by RAISE NOTICE;
2. by decreasing value of supplied {progress_seq} sequence from {total number of colums to search in} down to 0;
3. by writing the progress along with found tables into text file, located in c:\windows\temp\{progress_seq}.txt.

Now with Ruby 2.3 you can use &. operator ('lonely operator') to check for nil at the same time as accessing a value.

@person&.spouse&.name

https://en.wikibooks.org/wiki/Ruby_Programming/Syntax/Operators#Other_operators

Use #try instead so you don't have to keep checking for nil.

http://api.rubyonrails.org/classes/Object.html#method-i-try

@person.try(:spouse).try(:name)

instead of

@person.spouse.name if @person && @person.spouse

Try this

$('#thisElement .classToSelect').each(function(i){
         // do stuff
});

Hope it will help

You could use remove(). More information on jQuery remove().

$(this).children("ul").remove();

Note that this will remove all ul elements that are children.

Easy codes that work successfully:

Scripts are usually loaded in the end of the html page, and MVC recommends the using of bundles, just saying. So my best bet is that your jquery.validate files got altered in some way or are not updated to the latest version, since they do validate e-mail inputs.

So you could either update/refresh your nuget package or write your own function, really.

Here's an example which you would add in an extra file after jquery.validate.unobtrusive:

$.validator.addMethod(
    "email",
    function (value, element) {
        return this.optional( element ) || /^[a-zA-Z0-9.!#$%&'*+\/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/.test( value );
    },
    "This e-mail is not valid"
);

This is just a copy and paste of the current jquery.validate Regex, but this way you could set your custom error message/add extra methods to fields you might want to validate in the near future.

Here is a straight way to convert the UTC time of the questioner to local time. This is for a stored time in a database etc., i.e. any time. You just have to find the time difference between UTC time and the local time you are interested in and then ajust the stored UTC time adding to it the difference.

$df = "G:i:s";  // Use a simple time format to find the difference
$ts1 = strtotime(date($df));   // Timestamp of current local time
$ts2 = strtotime(gmdate($df)); // Timestamp of current UTC time
$ts3 = $ts1-$ts2;              // Their difference

You can then add this difference to the stored UTC time. (In my place, Athens, the difference is exactly 5:00:00)

Example:

$time = time() // Or any other timestamp
$time += $ts3  // Add the difference
$dateInLocal = date("Y-m-d H:i:s", $time);

INSERT INTO DestinationTable(SupplierName, Country)
SELECT SupplierName, Country FROM SourceTable;

It is not mandatory column names to be same.

In Bootstrap 3 I've added a table-no-border class

.table-no-border>thead>tr>th, 
.table-no-border>tbody>tr>th, 
.table-no-border>tfoot>tr>th, 
.table-no-border>thead>tr>td, 
.table-no-border>tbody>tr>td, 
.table-no-border>tfoot>tr>td {
  border-top: none; 
}

Here is the snippets from my code.. If it solves your problems..

Client Code :

Set jsonpCallBack : 'photos' and dataType:'jsonp'

 $('document').ready(function() {
            var pm_url = 'http://localhost:8080/diztal/rest/login/test_cor?sessionKey=4324234';
            $.ajax({
                crossDomain: true,
                url: pm_url,
                type: 'GET',
                dataType: 'jsonp',
                jsonpCallback: 'photos'
            });
        });
        function photos (data) {
            alert(data);
            $("#twitter_followers").html(data.responseCode);
        };

Server Side Code (Using Rest Easy)

@Path("/test_cor")
@GET
@Produces(MediaType.TEXT_PLAIN)
public String testCOR(@QueryParam("sessionKey") String sessionKey, @Context HttpServletRequest httpRequest) {
    ResponseJSON<LoginResponse> resp = new ResponseJSON<LoginResponse>();
    resp.setResponseCode(sessionKey);
    resp.setResponseText("Wrong Passcode");
    resp.setResponseTypeClass("Login");
    Gson gson = new Gson();
    return "photos("+gson.toJson(resp)+")"; // CHECK_THIS_LINE
}

You can just simply add the following code;

<a class="btn btn-primary" href="http://localhost:8080/Home" role="button">Home Page</a>

You could do this easily using array reduce in ES6

In this example we create a reducer function and pass an object '{}' as initial value to the reduce function along with the reducer

const arr =    [ [ 'cardType', 'iDEBIT' ],_x000D_
  [ 'txnAmount', '17.64' ],_x000D_
  [ 'txnId', '20181' ],_x000D_
  [ 'txnType', 'Purchase' ],_x000D_
  [ 'txnDate', '2015/08/13 21:50:04' ],_x000D_
  [ 'respCode', '0' ],_x000D_
  [ 'isoCode', '0' ],_x000D_
  [ 'authCode', '' ],_x000D_
  [ 'acquirerInvoice', '0' ],_x000D_
  [ 'message', '' ],_x000D_
  [ 'isComplete', 'true' ],_x000D_
  [ 'isTimeout', 'false' ] ];_x000D_
_x000D_
const reducer = (obj, item) => {_x000D_
  obj[item[0]] = item[1];_x000D_
  return obj;_x000D_
};_x000D_
_x000D_
const result = arr.reduce(reducer, {});_x000D_
_x000D_
console.log(result);

Use -1 index (negative indices count backward from the end of the array):

a[-1] # => 5
b[-1] # => 6

or Array#last method:

a.last # => 5
b.last # => 6

$('.tabDisable').on('keydown', function(e)
{ 
  if (e.keyCode == 9)  
  {
    e.preventDefault();
  }
});

Put .tabDisable to all tab disable DIVs Like

<div class='tabDisable'>First Div</div> <!-- Tab Disable Div -->
<div >Second Div</div> <!-- No Tab Disable Div -->
<div class='tabDisable'>Third Div</div> <!-- Tab Disable Div -->

Emoji

You can use colors for text as others mentioned in their answers.

But you can use emojis instead! for example you can use You can use ?? for warning messages and for error messages.

Or simply use these note books as a color:

: error message
: warning message
: ok status message
: action message
: canceled status message
: Or anything you like and want to recognize immediately by color

Bonus:

This method also helps you to quickly scan and find logs directly in the source code.

_{But linux and Windows CMD default emoji font is not colorful by default and you may want to make them colorful, first.}

C#'s ArrayList class has a Synchronized method.

var threadSafeArrayList = ArrayList.Synchronized(new ArrayList());

This returns a thread safe wrapper around any instance of IList. All operations need to be performed through the wrapper to ensure thread safety.

shell_command = "ls -l" subprocess.call(shell_command.split())

Just drop the option v.

-v is for verbose. If you don't use it then it won't display:

Including the implementation file (test.c) causes it to be prepended to your main.c and complied there and then again separately. So, the function test has two definitions -- one in the object code of main.c and once in that of test.c, which gives you a ODR violation. You need to create a header file containing the declaration of test and include it in main.c:

/* test.h */
#ifndef TEST_H
#define TEST_H
void test(); /* declaration */
#endif /* TEST_H */

For the new Criteria since version Hibernate 5.2:

CriteriaBuilder criteriaBuilder = getSession().getCriteriaBuilder();
CriteriaQuery<SomeClass> criteriaQuery = criteriaBuilder.createQuery(SomeClass.class);

Root<SomeClass> root = criteriaQuery.from(SomeClass.class);

Path<Object> expressionA = root.get("A");
Path<Object> expressionB = root.get("B");

Predicate predicateAEqualX = criteriaBuilder.equal(expressionA, "X");
Predicate predicateBInXY = expressionB.in("X",Y);
Predicate predicateLeft = criteriaBuilder.and(predicateAEqualX, predicateBInXY);

Predicate predicateAEqualY = criteriaBuilder.equal(expressionA, Y);
Predicate predicateBEqualZ = criteriaBuilder.equal(expressionB, "Z");
Predicate predicateRight = criteriaBuilder.and(predicateAEqualY, predicateBEqualZ);

Predicate predicateResult = criteriaBuilder.or(predicateLeft, predicateRight);

criteriaQuery
        .select(root)
        .where(predicateResult);

List<SomeClass> list = getSession()
        .createQuery(criteriaQuery)
        .getResultList();  

You can use something like JoSQL, and write 'SQL' against your collections: http://josql.sourceforge.net/

Which sounds like what you want, with the added benefit of being able to do more complicated queries.

• Changing Values:
  • array_map cannot change the values inside input array(s) while array_walk can; in particular, array_map never changes its arguments.
• Array Keys Access:
  • array_map cannot operate with the array keys, array_walk can.
• Return Value:
  • array_map returns a new array, array_walk only returns true. Hence, if you don't want to create an array as a result of traversing one array, you should use array_walk.
• Iterating Multiple Arrays:
  • array_map also can receive an arbitrary number of arrays and it can iterate over them in parallel, while array_walk operates only on one.
• Passing Arbitrary Data to Callback:
  • array_walk can receive an extra arbitrary parameter to pass to the callback. This mostly irrelevant since PHP 5.3 (when anonymous functions were introduced).
• Length of Returned Array:
  • The resulting array of array_map has the same length as that of the largest input array; array_walk does not return an array but at the same time it cannot alter the number of elements of original array; array_filter picks only a subset of the elements of the array according to a filtering function. It does preserve the keys.

Example:

<pre>
<?php

$origarray1 = array(2.4, 2.6, 3.5);
$origarray2 = array(2.4, 2.6, 3.5);

print_r(array_map('floor', $origarray1)); // $origarray1 stays the same

// changes $origarray2
array_walk($origarray2, function (&$v, $k) { $v = floor($v); }); 
print_r($origarray2);

// this is a more proper use of array_walk
array_walk($origarray1, function ($v, $k) { echo "$k => $v", "\n"; });

// array_map accepts several arrays
print_r(
    array_map(function ($a, $b) { return $a * $b; }, $origarray1, $origarray2)
);

// select only elements that are > 2.5
print_r(
    array_filter($origarray1, function ($a) { return $a > 2.5; })
);

?>
</pre>

Result:

Array
(
    [0] => 2
    [1] => 2
    [2] => 3
)
Array
(
    [0] => 2
    [1] => 2

I have taken UITableView with custom prototype cell class named UITableViewCell inside UIViewController.

So i have ViewController.h, ViewController.m and TableViewCell.h,TableViewCell.m

Here is the code for that:

ViewController.h

@interface ViewController : UIViewController<UITableViewDataSource,UITableViewDelegate>

@property (strong, nonatomic) IBOutlet UITableView *tblView;

@end

ViewController.m

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return (YourNumberOfRows);
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *cellIdentifier = @"cell";

    __weak TableViewCell *cell = (TableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];

    if (indexPath.row==0) {
        [cell setDidTapButtonBlock:^(id sender)
         {
             // Your code here

         }];
    }    
    return cell;
}

Custom cell class :

TableViewCell.h

@interface TableViewCell : UITableViewCell

@property (copy, nonatomic) void (^didTapButtonBlock)(id sender);

@property (strong, nonatomic) IBOutlet UILabel *lblTitle;
@property (strong, nonatomic) IBOutlet UIButton *btnAction;

- (void)setDidTapButtonBlock:(void (^)(id sender))didTapButtonBlock;

@end

and

UITableViewCell.m

@implementation TableViewCell

- (void)awakeFromNib {
    // Initialization code
    [self.btnAction addTarget:self action:@selector(didTapButton:) forControlEvents:UIControlEventTouchUpInside];

}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}
- (void)didTapButton:(id)sender {
    if (self.didTapButtonBlock)
    {
        self.didTapButtonBlock(sender);
    }
}

You can download the inf file from here - Introducing PowerShell Prompt Here

I was having same kind of problem with ldap, intl, curl php extensions. I've solved those issues by the following ways:

At first you've to check whether these extensions have been enabled in the php.ini file by removing semicolon (;) in front of the following lines:

;extension=php_intl.dll
;extension=php_ldap.dll
;extension=php_curl.dll

Secondly, libeay32.dll, ibssh2.dll and ssleay32.dll files have to be loaded by php properly to function those extensions properly. These dll files are required by several php extensions (ie curl, ldap, intl etc). These files generally reside in the php installation directory [for my case it is C:\php directory]. Additionally, for intl extension to be enabled you're gonna need some other dll files to be loaded by php properly. The name of these files begin with icu (ie icudt57.dll icuin57.dll etc for php version 5.6). You'll also find these files in the php main installation directory.

There is a alternate way you can load these files from your httpd.conf (apache configuratio file) file instead of copying them to the apache's bin directory. This can be done by using the following technique:

Please note that my php version is 5.5.

LoadFile  "C:/php/icudt51.dll"
LoadFile  "C:/php/icuin51.dll"
LoadFile  "C:/php/icuio51.dll"
LoadFile  "C:/php/icule51.dll"
LoadFile  "C:/php/iculx51.dll"
LoadFile  "C:/php/icutest51.dll"
LoadFile  "C:/php/icutu51.dll"
LoadFile  "C:/php/icuuc51.dll"

LoadFile  "C:/php/libeay32.dll"
LoadFile  "C:/php/libssh2.dll"
LoadFile  "C:/php/ssleay32.dll"

 That's it.

Use the annotation @Deprecated for your method, and you should also mention it in your javadocs.

Its a function that calls itself. Its useful for walking certain data structures that repeat themselves, such as trees. An HTML DOM is a classic example.

An example of a tree structure in javascript and a recursive function to 'walk' the tree.

    1
   / \
  2   3
     / \
    4   5

--

var tree = {
  id: 1,
  left: {
    id: 2,
    left: null,
    right: null
  },
  right: {
    id: 3,
    left: {
      id: 4,
      left: null,
      right: null
    },
    right: {
      id: 5,
      left: null,
      right: null
    }
  }
};

To walk the tree, we call the same function repeatedly, passing the child nodes of the current node to the same function. We then call the function again, first on the left node, and then on the right.

In this example, we'll get the maximum depth of the tree

var depth = 0;

function walkTree(node, i) {

  //Increment our depth counter and check
  i++;
  if (i > depth) depth = i;

  //call this function again for each of the branch nodes (recursion!)
  if (node.left != null) walkTree(node.left, i);
  if (node.right != null) walkTree(node.right, i);

  //Decrement our depth counter before going back up the call stack
  i--;
}

Finally we call the function

alert('Tree depth:' + walkTree(tree, 0));

A great way of understanding recursion is to step through the code at runtime.

I want columns One and Two to shrink/grow to fit rather than being fixed.

Have you tried: flex-basis: auto

or this:

flex: 1 1 auto, which is short for:

• flex-grow: 1 (grow proportionally)
• flex-shrink: 1 (shrink proportionally)
• flex-basis: auto (initial size based on content size)

or this:

main > section:first-child {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:nth-child(2) {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:last-child {
    flex: 20 1 auto;
    display: flex;
    flex-direction: column;  
}

Why setContentView() in Android Had Been So Popular Till Now?

setContentView(int layoutid) - method of activity class. It shows layout on screen.

R.layout.main - is an integer number implemented in nested layout class of R.java class file.

At the run time device will pick up their layout based on the id given in setcontentview() method.

Npm and Bower are both dependency management tools. But the main difference between both is npm is used for installing Node js modules but bower js is used for managing front end components like html, css, js etc.

A fact that makes this more confusing is that npm provides some packages which can be used in front-end development as well, like grunt and jshint.

These lines add more meaning

Bower, unlike npm, can have multiple files (e.g. .js, .css, .html, .png, .ttf) which are considered the main file(s). Bower semantically considers these main files, when packaged together, a component.

Edit: Grunt is quite different from Npm and Bower. Grunt is a javascript task runner tool. You can do a lot of things using grunt which you had to do manually otherwise. Highlighting some of the uses of Grunt:

1. Zipping some files (e.g. zipup plugin)
2. Linting on js files (jshint)
3. Compiling less files (grunt-contrib-less)

There are grunt plugins for sass compilation, uglifying your javascript, copy files/folders, minifying javascript etc.

Please Note that grunt plugin is also an npm package.

Question-1

When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json

It really depends where does this package belong to. If it is a node module(like grunt,request) then it will go in package.json otherwise into bower json.

Question-2

When should I ever install packages explicitly like that without adding them to the file that manages dependencies

It does not matter whether you are installing packages explicitly or mentioning the dependency in .json file. Suppose you are in the middle of working on a node project and you need another project, say request, then you have two options:

• Edit the package.json file and add a dependency on 'request'
• npm install

OR

• Use commandline: npm install --save request

--save options adds the dependency to package.json file as well. If you don't specify --save option, it will only download the package but the json file will be unaffected.

You can do this either way, there will not be a substantial difference.

Use \Q to autoescape any potentially problematic characters in your variable.

if($text_to_search =~ m/\Q$search_string/) print "wee";

I find this approach a bit more flexible, here you just providing generator function that emits key, value pairs and can be easily extended to also iterate over lists.

def traverse(value, key=None):
    if isinstance(value, dict):
        for k, v in value.items():
            yield from traverse(v, k)
    else:
        yield key, value

Then you can write your own myprint function, then would print those key value pairs.

def myprint(d):
    for k, v in traverse(d):
        print(f"{k} : {v}")

A test:

myprint({
    'xml': {
        'config': {
            'portstatus': {
                'status': 'good',
            },
            'target': '1',
        },
        'port': '11',
    },
})

Output:

status : good
target : 1
port : 11

I tested this on Python 3.6.

It is not too surprising: the execution plan for the tiny insert is computed once, and then reused 1000 times. Parsing and preparing the plan is quick, because it has only four values to del with. A 1000-row plan, on the other hand, needs to deal with 4000 values (or 4000 parameters if you parameterized your C# tests). This could easily eat up the time savings you gain by eliminating 999 roundtrips to SQL Server, especially if your network is not overly slow.

It should be implemented as a free, non-friend functions, especially if, like most things these days, the output is mainly used for diagnostics and logging. Add const accessors for all the things that need to go into the output, and then have the outputter just call those and do formatting.

I've actually taken to collecting all of these ostream output free functions in an "ostreamhelpers" header and implementation file, it keeps that secondary functionality far away from the real purpose of the classes.

Personally I am not sure how anything using regular expressions in python can be described as elegant. Most answers here are just doing "code golf" type RE tricks. Elegant coding is supposed to be easily understood.

def to_snake_case(not_snake_case):
    final = ''
    for i in xrange(len(not_snake_case)):
        item = not_snake_case[i]
        if i < len(not_snake_case) - 1:
            next_char_will_be_underscored = (
                not_snake_case[i+1] == "_" or
                not_snake_case[i+1] == " " or
                not_snake_case[i+1].isupper()
            )
        if (item == " " or item == "_") and next_char_will_be_underscored:
            continue
        elif (item == " " or item == "_"):
            final += "_"
        elif item.isupper():
            final += "_"+item.lower()
        else:
            final += item
    if final[0] == "_":
        final = final[1:]
    return final

You can use Collections for to sort data:

import java.util.Collections;
import java.util.ArrayList;
import java.util.List;

public class tes
{
    public static void main(String args[])
    {
        List<Integer> lList = new ArrayList<Integer>();

        lList.add(4);       
        lList.add(1);
        lList.add(7);
        lList.add(2);
        lList.add(9);
        lList.add(1);
        lList.add(5);

        Collections.sort(lList);

        for(int i=0; i<lList.size();i++ )
        {
            System.out.println(lList.get(i));
        }

    }
}

Just use the constructor for the vector that takes iterators:

std::set<T> s;

//...

std::vector v( s.begin(), s.end() );

Assumes you just want the content of s in v, and there's nothing in v prior to copying the data to it.

You can try with

var result = DateTime.Now.ToString("yyyy-MM-d--HH-mm-ss");

For i=1 To 10
    Do 
        'Do everything in here and

        If I_Dont_Want_Finish_This_Loop Then
            Exit Do
        End If 

        'Of course, if I do want to finish it,
        'I put more stuff here, and then...

    Loop While False 'quit after one loop
Next i

Using DISTINCT should do it:

SELECT DISTINCT id, uname, tel
FROM YourTable

Though you could really do with having a primary key on that table, a way to uniquely identify each record. I'd be considering sticking an IDENTITY column on the table

For the CTRL+C case, you can use this:

// Tell the system console to handle CTRL+C by calling our method that
// gracefully shuts down.
Console.CancelKeyPress += new ConsoleCancelEventHandler(Console_CancelKeyPress);


static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
{
            Console.WriteLine("Shutting down...");
            // Cleanup here
            System.Threading.Thread.Sleep(750);
}

Currently, setTextSize(float size) method will work well so we don't need to use another method for change text size

android.widget.TextView.java source code

/**
 * Set the default text size to the given value, interpreted as "scaled
 * pixel" units.  This size is adjusted based on the current density and
 * user font size preference.
 *
 * <p>Note: if this TextView has the auto-size feature enabled than this function is no-op.
 *
 * @param size The scaled pixel size.
 *
 * @attr ref android.R.styleable#TextView_textSize
 */
@android.view.RemotableViewMethod
public void setTextSize(float size) {
    setTextSize(TypedValue.COMPLEX_UNIT_SP, size);
}

Example using

textView.setTextSize(20); // set your text size = 20sp

Since April 2018, Google made some changes to the Autoplay Policy. You not only need to add the autoplay=1 as a query param, but also add allow='autoplay' as an iframe's attribute

Kill The Group Using Only Name of Process Which Belongs to Group:

kill -- -$(ps -ae o pid,pgrp,cmd | grep "[e]xample.py" | awk '{print $2}' | tail -1)

This is a modification of olibre's answer but you don't need to know the PID, just the name of a member of the group.

Explanation:

To get the group id you do the ps command using the arguments as shown, grep it for your command, but formatting example.py with quotes and using the bracket for the first letter (this filters out the grep command itself) then filter it through awk to get the second field which is the group id. The tail -1 gets rid of duplicate group ids. You put all of that in a variable using the $() syntax and voila – you get the group id. So you substitute that $(mess) for that -groupid above.

It is not the operator that is case sensitive, it is the column itself.

When a SQL Server installation is performed a default collation is chosen to the instance. Unless explicitly mentioned otherwise (check the collate clause bellow) when a new database is created it inherits the collation from the instance and when a new column is created it inherits the collation from the database it belongs.

A collation like sql_latin1_general_cp1_ci_as dictates how the content of the column should be treated. CI stands for case insensitive and AS stands for accent sensitive.

A complete list of collations is available at https://msdn.microsoft.com/en-us/library/ms144250(v=sql.105).aspx

(a) To check a instance collation

select serverproperty('collation')

(b) To check a database collation

select databasepropertyex('databasename', 'collation') sqlcollation

(c) To create a database using a different collation

create database exampledatabase
collate sql_latin1_general_cp1_cs_as 

(d) To create a column using a different collation

create table exampletable (
    examplecolumn varchar(10) collate sql_latin1_general_cp1_ci_as null
)

(e) To modify a column collation

alter table exampletable
alter column examplecolumn varchar(10) collate sql_latin1_general_cp1_ci_as null

It is possible to change a instance and database collations but it does not affect previously created objects.

It is also possible to change a column collation on the fly for string comparison, but this is highly unrecommended in a production environment because it is extremely costly.

select
  column1 collate sql_latin1_general_cp1_ci_as as column1
from table1

Old question, but I'm surprised no one has mentioned ilmerge yet. ilmerge is from Microsoft, but not shipped with VS or the SDKs. You can download it from here though. There is also a github repository. You can also install from nuget:

PM>Install-Package ilmerge

To use:

ilmerge assembly.dll /keyfile:key.snk /out:assembly.dll /targetplatform:v4,C:\Windows\Microsoft.NET\Framework\v4.0.30319 /ndebug

If needed, You can generate your own keyfile using sn (from VS):

sn -k key.snk

<h:button>

The <h:button> generates a HTML <input type="button">. The generated element uses JavaScript to navigate to the page given by the attribute outcome, using a HTTP GET request.

E.g.

<h:button value="GET button" outcome="otherpage" />

will generate

<input type="button" onclick="window.location.href='/contextpath/otherpage.xhtml'; return false;" value="GET button" />

Even though this ends up in a (bookmarkable) URL change in the browser address bar, this is not SEO-friendly. Searchbots won't follow the URL in the onclick. You'd better use a <h:outputLink> or <h:link> if SEO is important on the given URL. You could if necessary throw in some CSS on the generated HTML <a> element to make it to look like a button.

Do note that while you can put an EL expression referring a method in outcome attribute as below,

<h:button value="GET button" outcome="#{bean.getOutcome()}" />

it will not be invoked when you click the button. Instead, it is already invoked when the page containing the button is rendered for the sole purpose to obtain the navigation outcome to be embedded in the generated onclick code. If you ever attempted to use the action method syntax as in outcome="#{bean.action}", you would already be hinted by this mistake/misconception by facing a javax.el.ELException: Could not find property actionMethod in class com.example.Bean.

If you intend to invoke a method as result of a POST request, use <h:commandButton> instead, see below. Or if you intend to invoke a method as result of a GET request, head to Invoke JSF managed bean action on page load or if you also have GET request parameters via <f:param>, How do I process GET query string URL parameters in backing bean on page load?

<h:commandButton>

The <h:commandButton> generates a HTML <input type="submit"> button which submits by default the parent <h:form> using HTTP POST method and invokes the actions attached to action, actionListener and/or <f:ajax listener>, if any. The <h:form> is required.

E.g.

<h:form id="form">
    <h:commandButton id="button" value="POST button" action="otherpage" />
</h:form>

will generate

<form id="form" name="form" method="post" action="/contextpath/currentpage.xhtml" enctype="application/x-www-form-urlencoded">
    <input type="hidden" name="form" value="form" />
    <input type="submit" name="form:button" value="POST button" />
    <input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="...." autocomplete="off" />
</form>

Note that it thus submits to the current page (the form action URL will show up in the browser address bar). It will afterwards forward to the target page, without any change in the URL in the browser address bar. You could add ?faces-redirect=true parameter to the outcome value to trigger a redirect after POST (as per the Post-Redirect-Get pattern) so that the target URL becomes bookmarkable.

The <h:commandButton> is usually exclusively used to submit a POST form, not to perform page-to-page navigation. Normally, the action points to some business action, such as saving the form data in DB, which returns a String outcome.

<h:commandButton ... action="#{bean.save}" />

with

public String save() {
    // ...
    return "otherpage";
}

Returning null or void will bring you back to the same view. Returning an empty string also, but it would recreate any view scoped bean. These days, with modern JSF2 and <f:ajax>, more than often actions just return to the same view (thus, null or void) wherein the results are conditionally rendered by ajax.

public void save() {
    // ...
}

np.unique works given a list of tuples:

>>> np.unique([(1, 1), (2, 2), (3, 3), (4, 4), (2, 2)])
Out[9]: 
array([[1, 1],
       [2, 2],
       [3, 3],
       [4, 4]])

With a list of lists it raises a TypeError: unhashable type: 'list'

First of all you should use double "==" instead of "=" to compare two values. Using "=" You assigning value to variable in this case "somevar"

Aside from personal design preferences, there are cases where one wants to make use of composite primary keys. Tables may have two or more fields that provide a unique combination, and not necessarily by way of foreign keys.

As an example, each US state has a set of unique Congressional districts. While many states may individually have a CD-5, there will never be more than one CD-5 in any of the 50 states, and vice versa. Therefore, creating an autonumber field for Massachusetts CD-5 would be redundant.

If the database drives a dynamic web page, writing code to query on a two-field combination could be much simpler than extracting/resubmitting an autonumbered key.

So while I'm not answering the original question, I certainly appreciate Adam's direct answer.

The simple way to get (one) element from array by id:

The find() method returns the value of the first element in the array that satisfies the provided testing function. Otherwise undefined is returned.

function isBigEnough(element) {
    return element >= 15;
}

var integers = [12, 5, 8, 130, 160, 44];
integers.find(isBigEnough); // 130  only one element - first

you don't need to use filter() and catch first element xx.filter()[0] like in comments above

The same for objects in array

var foo = {
"results" : [{
    "id" : 1,
    "name" : "Test"
}, {
    "id" : 2,
    "name" : "Beispiel"
}, {
    "id" : 3,
    "name" : "Sample"
}
]};

var secondElement = foo.results.find(function(item){
    return item.id == 2;
});

var json = JSON.stringify(secondElement);
console.log(json);

Of course if you have multiple id then use filter() method to get all objects. Cheers

function isBigEnough(element) {_x000D_
    return element >= 15;_x000D_
}_x000D_
_x000D_
var integers = [12, 5, 8, 130, 160, 44];_x000D_

var foo = {_x000D_

Why not try:

import datetime as dt

start_date = dt.datetime(2012, 12,1)
end_date = dt.datetime(2012, 12,5)

total_days = (end_date - start_date).days + 1 #inclusive 5 days

for day_number in range(total_days):
    current_date = (start_date + dt.timedelta(days = day_number)).date()
    print current_date

tesseract  --tessdata-dir <tessdata-folder> <image-path> stdout --oem 2 -l <lng>

In my case, the mistakes that I've made or attempts that wasn't a success.

• I cloned the github repo and copied files from there to
  • /usr/local/share/tessdata/
  • /usr/share/tesseract-ocr/tessdata/
  • /usr/share/tessdata/
• Used TESSDATA_PREFIX with above paths
• sudo apt-get install tesseract-ocr-eng

First 2 attempts did not worked because, the files from git clone did not worked for the reasons that I do not know. I am not sure why #3 attempt worked for me.

Finally,

1. I downloaded the eng.traindata file using wget
2. Copied it to some directory
3. Used --tessdata-dir with directory name

Take away for me is to learn the tool well & make use of it, rather than relying on package manager installation & directories

You are splitting a string on a fairly complex sub string. I'd use regular expressions instead of String.Split. The later is more for tokenizing you text.

For example:

var rx = new System.Text.RegularExpressions.Regex("is Marco and");
var array = rx.Split("My name is Marco and I'm from Italy");

In ES6 / ES2015, you can iterate over an string with iterators,as you can see in

Symbol.iterator MDN

var str = 'Hello';
var it = str[Symbol.iterator]();

for (let v of it) {
  console.log(v)
 }
 
//  "H"
//  "e"
//  "l"
//  "l"
//  "o"

It is a declarative style. What is the advantage? You do not have to concern about how to access each element of the string.

I say you setup the JAVA_HOME environment variable like Pascal is saying: In Cygwin if you use bash as your shell should be:

export JAVA_HOME=/cygdrive/c/pathtothejdk

It never harms to also prepend the java bin directory path to the PATH environment variable with:

export PATH=${JAVA_HOME}/bin:${PATH}

Also add maven-enforce-plugin to make sure the right JDK is used. This is a good practice for your pom.

<build>
 <plugins>
   <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-enforcer-plugin</artifactId>
      <executions>
        <execution>
          <id>enforce-versions</id>
          <goals>
            <goal>enforce</goal>
          </goals>
          <configuration>

          </configuration>
        </execution>

</build>

update

As BrianCampbell points out here, SQLite 3.7.11 and above now supports the simpler syntax of the original post. However, the approach shown is still appropriate if you want maximum compatibility across legacy databases.

original answer

If I had privileges, I would bump river's reply: You can insert multiple rows in SQLite, you just need different syntax. To make it perfectly clear, the OPs MySQL example:

INSERT INTO 'tablename' ('column1', 'column2') VALUES
  ('data1', 'data2'),
  ('data1', 'data2'),
  ('data1', 'data2'),
  ('data1', 'data2');

This can be recast into SQLite as:

     INSERT INTO 'tablename'
          SELECT 'data1' AS 'column1', 'data2' AS 'column2'
UNION ALL SELECT 'data1', 'data2'
UNION ALL SELECT 'data1', 'data2'
UNION ALL SELECT 'data1', 'data2'

a note on performance

I originally used this technique to efficiently load large datasets from Ruby on Rails. However, as Jaime Cook points out, it's not clear this is any faster wrapping individual INSERTs within a single transaction:

BEGIN TRANSACTION;
INSERT INTO 'tablename' table VALUES ('data1', 'data2');
INSERT INTO 'tablename' table VALUES ('data3', 'data4');
...
COMMIT;

If efficiency is your goal, you should try this first.

a note on UNION vs UNION ALL

As several people commented, if you use UNION ALL (as shown above), all rows will be inserted, so in this case, you'd get four rows of data1, data2. If you omit the ALL, then duplicate rows will be eliminated (and the operation will presumably be a bit slower). We're using UNION ALL since it more closely matches the semantics of the original post.

in closing

P.S.: Please +1 river's reply, as it presented the solution first.

If the culture of the result doesn't matters or we're only talking of integer values, CONVERT or CAST will be fine.

However, if the result must match a specific culture, FORMAT might be the function to go:

DECLARE @value DECIMAL(19,4) = 1505.5698
SELECT CONVERT(NVARCHAR, @value)        -->  1505.5698
SELECT FORMAT(@value, 'N2', 'en-us')    --> 1,505.57
SELECT FORMAT(@value, 'N2', 'de-de')    --> 1.505,57

For more information on FORMAT see here.

Of course, formatting the result should be a matter of the UI layer of the software.

Using Gson

    List<Student> students = new ArrayList<>();
    JSONArray jsonArray = new JSONArray(stringJsonContainArray);
    for (int i = 0; i < jsonArray.length(); i++) {
        Student student = new Gson().fromJson(jsonArray.get(i).toString(), Student.class);
        students.add(student);
    }
    return students;

If you want to have an unique list of objects returned back. here is another alternative:

const unique = (arr, encoder=JSON.stringify, decoder=JSON.parse) =>
  [...new Set(arr.map(item => encoder(item)))].map(item => decoder(item));

Which will turn this:

unique([{"name": "john"}, {"name": "sarah"}, {"name": "john"}])

into

[{"name": "john"}, {"name": "sarah"}]

The trick here is that we are first encoding the items into strings using JSON.stringify, and then we are converting that to a Set (which makes the list of strings unique) and then we are converting it back to the original objects using JSON.parse.

Add this connection string tag in web.config file:

<connectionStrings>
  <add name="itmall" 
    connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=D:\19-02\ABCC\App_Data\abcc.mdf;Integrated Security=True;User Instance=True"/>
</connectionStrings>

And use it like you mentioned. :)

Do not depend on ADB shell, just treat it (the adb logcat) a normal linux output and then pip it:

$ adb shell logcat | grep YouTag
# just like: 
$ ps -ef | grep your_proc 

As suggested by @[Tomasz Zielinski] and @Williams python-dateutil can do it just 5 lines.

from dateutil.relativedelta import *
from datetime import date
today = date.today()
dob = date(1982, 7, 5)
age = relativedelta(today, dob)

>>relativedelta(years=+33, months=+11, days=+16)`

For my case on Ubuntu 14.04 installed with postgres 10.3. I need to follow the following steps

• su - postgres to switch user to postgres
• psql to enter postgres shell
• \password then enter your password
• \q to quit the shell session

• Then you switch back to root by executing exit and configure your pg_hba.conf (mine is at /etc/postgresql/10/main/pg_hba.conf) by making sure you have the following line

  local all postgres md5

• Restart your postgres service by service postgresql restart
• Now switch to postgres user and enter postgres shell again. It will prompt you with password.

Go to File > Project Structure > Select Module > Properties

After that CLICK on your project which will shown in LEFT PANEL

Then Select Properties Change Build Tool Version to 22.0.1

A statement contains a keyword.

An expression does not contain a keyword.

print "hello" is statement, because print is a keyword.

"hello" is an expression, but list compression is against this.

The following is an expression statement, and it is true without list comprehension:

(x*2 for x in range(10))

Bootstrap 4 (4.0.0-alpha.2) uses the css property column-count in the card-columns class to define how many columns of cards would be displayed inside the div element.
But this property has only two values:

• The default value 1 for small screens (max-width: 34em)
• The value 3 for all other sizes (min-width: 34em)

Here's how it is implemented in bootstrap.min.css :

@media (min-width: 34em) {
    .card-columns {
        -webkit-column-count:3;
        -moz-column-count:3;
        column-count:3;
        ?
    }
    ?
}

To make the card stacking responsive, you can add the following media queries to your css file and modify the values for min-width as per your requirements :

@media (min-width: 34em) {
    .card-columns {
        -webkit-column-count: 2;
        -moz-column-count: 2;
        column-count: 2;
    }
}

@media (min-width: 48em) {
    .card-columns {
        -webkit-column-count: 3;
        -moz-column-count: 3;
        column-count: 3;
    }
}

@media (min-width: 62em) {
    .card-columns {
        -webkit-column-count: 4;
        -moz-column-count: 4;
        column-count: 4;
    }
}

@media (min-width: 75em) {
    .card-columns {
        -webkit-column-count: 5;
        -moz-column-count: 5;
        column-count: 5;
    }
}

x86 means Intel 80x86 compatible. This used to include the 8086, a 16-bit only processor. Nowadays it roughly means any CPU with a 32-bit Intel compatible instruction set (usually anything from Pentium onwards). Never read x32 being used.

x64 means a CPU that is x86 compatible but has a 64-bit mode as well (most often the 64-bit instruction set as introduced by AMD is meant; Intel's idea of a 64-bit mode was totally stupid and luckily Intel admitted that and is now using AMDs variant).

So most of the time you can simplify it this way: x86 is Intel compatible in 32-bit mode, x64 is Intel compatible in 64-bit mode.

You are creating three lists, instead of using one (you don't use the return value of DirSearch(d)). You can use a list as a parameter to save the state:

static void Main(string[] args)
{
  var list = new List<string>();
  DirSearch(list, ".");

  foreach (var file in list)
  {
    Console.WriteLine(file);
  }
}

public static void DirSearch(List<string> files, string startDirectory)
{
  try
  {
    foreach (string file in Directory.GetFiles(startDirectory, "*.*"))
    {
      string extension = Path.GetExtension(file);

      if (extension != null)
      {
        files.Add(file);
      }
    }

    foreach (string directory in Directory.GetDirectories(startDirectory))
    {
      DirSearch(files, directory);
    }
  }
  catch (System.Exception e)
  {
    Console.WriteLine(e.Message);
  }
}

As others have said, OrderedDict is a superset of an ordered set in terms of functionality, but if you need a set for interacting with an API and don't need it to be mutable, OrderedDict.keys() is actually an implementation abc.collections.Set:

import random
from collections import OrderedDict, abc

a = list(range(0, 100))
random.shuffle(a)

# True
a == list(OrderedDict((i, 0) for i in a).keys())

# True
isinstance(OrderedDict().keys(), abc.Set)   

The caveats are immutability and having to build up the set like a dict, but it's simple and only uses built-ins.

make it simple

private void dataGridView1_cellformatting(object sender,DataGridViewCellFormattingEventArgs e)
{
     var amount = (int)e.Value;

     // return if rowCount = 0
     if (this.dataGridView1.Rows.Count == 0)
         return;

     if (amount > 0)
         e.CellStyle.BackColor = Color.Green; 
     else
         e.CellStyle.BackColor = Color.Red;

}

take a look cell formatting

Unfortunately stringification can not always be used as commenting out! So it is safer to stick to the standard prepending each line with a #.

Here is an example:

test1 = [1, 2, 3, 4,]       # test1 contains 4 integers

test2 = [1, 2, '''3, 4,'''] # test2 contains 2 integers **and the string** '3, 4,'

This doesn't show the window:

Process cmd = new Process();
cmd.StartInfo.FileName = "cmd.exe";
cmd.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
cmd.StartInfo.CreateNoWindow = true;

...
cmd.Start();

The solutions posted here don't work in non-ascii characters (i.e. if you plan to exchange base64 between Node.js and a browser). In order to make it work you have to mark the input text as 'binary'.

Buffer.from('Hélló wórld!!', 'binary').toString('base64')

This gives you SOlsbPMgd/NybGQhIQ==. If you make atob('SOlsbPMgd/NybGQhIQ==') in a browser it will decode it in the right way. It will do it right also in Node.js via:

Buffer.from('SOlsbPMgd/NybGQhIQ==', 'base64').toString('binary')

If you don't do the "binary part", you will decode wrongly the special chars.

Don't use array_values on your $row

$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
   {
       array_push($res_arr_values, $row);
   }

Also, the preferred way to add a value to an array is writing $array[] = $value;, not using array_push

$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
   {
       $res_arr_values[] = $row;
   }

And a further optimization is not to call mysql_fetch_array($result, MYSQL_ASSOC) but to use mysql_fetch_assoc($result) directly.

$res_arr_values = array();
while ($row = mysql_fetch_assoc($result))
   {
       $res_arr_values[] = $row;
   }

Maybe what you need is par(xpd=TRUE) to enable things to be drawn outside the plot region. So if you do the main plot with bty='L' you'll have some space on the right for a legend. Normally this would get clipped to the plot region, but do par(xpd=TRUE) and with a bit of adjustment you can get a legend as far right as it can go:

 set.seed(1) # just to get the same random numbers
 par(xpd=FALSE) # this is usually the default

 plot(1:3, rnorm(3), pch = 1, lty = 1, type = "o", ylim=c(-2,2), bty='L')
 # this legend gets clipped:
 legend(2.8,0,c("group A", "group B"), pch = c(1,2), lty = c(1,2))

 # so turn off clipping:
 par(xpd=TRUE)
 legend(2.8,-1,c("group A", "group B"), pch = c(1,2), lty = c(1,2))

If the user is interacting with another application, it may not be possible to bring yours to the front. As a general rule, a process can only expect to set the foreground window if that process is already the foreground process. (Microsoft documents the restrictions in the SetForegroundWindow() MSDN entry.) This is because:

1. The user "owns" the foreground. For example, it would be extremely annoying if another program stole the foreground while the user is typing, at the very least interrupting her workflow, and possibly causing unintended consequences as her keystrokes meant for one application are misinterpreted by the offender until she notices the change.
2. Imagine that each of two programs checks to see if its window is the foreground and attempts to set it to the foreground if it is not. As soon as the second program is running, the computer is rendered useless as the foreground bounces between the two at every task switch.

In python 3 you could use colorama - simple_colors: (Simple Colours page: https://pypi.org/project/simple-colors/ - go to the heading 'Usage'.) Before you do what is below, make sure you pip install simple_colours.

from simple_colors import *
print(green('hello', 'bold'))

Simple and easy:

$this->db->order_by("name", "asc");
$query = $this->db->get($this->table_name);
return $query->result();

You need to have cl.exe (the Microsoft C Compiler) installed on your computer and in your PATH. PATH is an environment variable that tells Windows where to find executable files.

First, ensure the C++ build tools for Visual Studio are installed. You can download Build Tools for Visual Studio separately from the Visual Studio downloads page, then choose C++ build tools from the installer. If you already have Visual Studio, you can also install Desktop development with C++ from the Visual Studio Installer which you should have in Start Menu.

Then, instead of the normal Command Prompt or PowerShell, use one of the special command prompts in the Visual Studio folder in Start Menu. For 32-bit Python, you're probably looking for x86 Native Tools Command Prompt. This sets up PATH automatically, so that cl.exe can be found.

Interesting observation using Java 11 and switching off loop unrolling with the following VM option:

-XX:LoopUnrollLimit=0

The loop with the 2 * (i * i) expression results in more compact native code¹:

L0001: add    eax,r11d
       inc    r8d
       mov    r11d,r8d
       imul   r11d,r8d
       shl    r11d,1h
       cmp    r8d,r10d
       jl     L0001

in comparison with the 2 * i * i version:

L0001: add    eax,r11d
       mov    r11d,r8d
       shl    r11d,1h
       add    r11d,2h
       inc    r8d
       imul   r11d,r8d

Yup. :) You can use Hipify to convert CUDA code very easily to HIP code which can be compiled run on both AMD and nVidia hardware pretty good. Here are some links

The prevailing thought is that the NOT operator may only be used to remove results from a query - not just exclude things out of the entire dataset. I happen to like the syntax you suggested mausch - thanks!

You split the string entry of the list. l[0].strip()

What about the SystemParameters class in PresentationFramework? It has a WorkArea property that seems to be what you are looking for.

But, why won't setting the Window.WindowStartupLocation work? CenterScreen is one of the enum values. Do you have to tweak the centering?

I am afraid there is no way to get the query string parameters parsed separately from the post parameters. BTW the fact that such API absent may mean that probably you should check your design. Why are you using query string when sending POST? If you really want to send more data into URL use REST-like convention, e.g. instead of sending

http://mycompany.com/myapp/myservlet?first=11&second=22

say:

http://mycompany.com/myapp/myservlet/11/22

You can do the flowing thing for monitoring mysql query logs.

Open mysql configuration file my.cnf

sudo nano /etc/mysql/my.cnf

Search following lines under a [mysqld] heading and uncomment these lines to enable log

general_log_file        = /var/log/mysql/mysql.log
general_log             = 1

Restart your mysql server for reflect changes

sudo service mysql start

Monitor mysql server log with following command in terminal

tail -f /var/log/mysql/mysql.log

The solution i found was

const [files, setFiles] = useState([] as any);

If your team uses descriptive commit messages (eg. "Ticket #12345 - Update dependencies") on this project, then generating changelog since the latest tag can de done like this:

git log --no-merges --pretty=format:"%s" 'old-tag^'...new-tag > /path/to/changelog.md

• --no-merges omits the merge commits from the list
• old-tag^ refers to the previous commit earlier than the tagged one. Useful if you want to see the tagged commit at the bottom of the list by any reason. (Single quotes needed only for iTerm on mac OS).

The syntax is

pid_t waitpid(pid_t pid, int *statusPtr, int options);

1.where pid is the process of the child it should wait.

2.statusPtr is a pointer to the location where status information for the terminating process is to be stored.

3.specifies optional actions for the waitpid function. Either of the following option flags may be specified, or they can be combined with a bitwise inclusive OR operator:

WNOHANG WUNTRACED WCONTINUED

If successful, waitpid returns the process ID of the terminated process whose status was reported. If unsuccessful, a -1 is returned.

benifits over wait

1.Waitpid can used when you have more than one child for the process and you want to wait for particular child to get its execution done before parent resumes

2.waitpid supports job control

3.it supports non blocking of the parent process

By default, np.genfromtxt uses dtype=float: that's why you string columns are converted to NaNs because, after all, they're Not A Number...

You can ask np.genfromtxt to try to guess the actual type of your columns by using dtype=None:

>>> from StringIO import StringIO
>>> test = "a,1,2\nb,3,4"
>>> a = np.genfromtxt(StringIO(test), delimiter=",", dtype=None)
>>> print a
array([('a',1,2),('b',3,4)], dtype=[('f0', '|S1'),('f1', '<i8'),('f2', '<i8')])

You can access the columns by using their name, like a['f0']...

Using dtype=None is a good trick if you don't know what your columns should be. If you already know what type they should have, you can give an explicit dtype. For example, in our test, we know that the first column is a string, the second an int, and we want the third to be a float. We would then use

>>> np.genfromtxt(StringIO(test), delimiter=",", dtype=("|S10", int, float))
array([('a', 1, 2.0), ('b', 3, 4.0)], 
      dtype=[('f0', '|S10'), ('f1', '<i8'), ('f2', '<f8')])

Using an explicit dtype is much more efficient than using dtype=None and is the recommended way.

In both cases (dtype=None or explicit, non-homogeneous dtype), you end up with a structured array.

[Note: With dtype=None, the input is parsed a second time and the type of each column is updated to match the larger type possible: first we try a bool, then an int, then a float, then a complex, then we keep a string if all else fails. The implementation is rather clunky, actually. There had been some attempts to make the type guessing more efficient (using regexp), but nothing that stuck so far]

Do you mean you want to tell your copy of IE 10 to render the pages it views in IE 9 mode?

Or do you mean you want your website to force IE 10 to render it in IE 9 mode?

For the former:

To force a webpage you are viewing in Internet Explorer 10 into a particular document compatibility mode, first open F12 Tools by pressing the F12 key. Then, on the Browser Mode menu, click Internet Explorer 10, and on the Document Mode menu, click Standards.

http://msdn.microsoft.com/en-gb/library/ie/hh920756(v=vs.85).aspx

For the latter, the other answers are correct, but I wouldn't advise doing that. IE 10 is more standards-compliant (i.e. more similar to other browsers) than IE 9.

To untrack a single file that has already been added/initialized to your repository, i.e., stop tracking the file but not delete it from your system use: git rm --cached filename

To untrack every file that is now in your .gitignore:

First commit any outstanding code changes, and then, run this command:

git rm -r --cached .

This removes any changed files from the index(staging area), then just run:

git add .

Commit it:

git commit -m ".gitignore is now working"

In Swift 3 :

It will generate random number between 0 to limit

let limit : UInt32 = 6
print("Random Number : \(arc4random_uniform(limit))")

Give this a go:

string format = "{0} / {1} / {2} {3}";
string date = string.Format(format,mon.ToString(),da.ToString(),yer.ToString();
Console.WriteLine(date);

In fact, there's probably a way to format it automatically without even doing it yourself.

Everybody proposes a way to reverse string here. If you, the reader of the answer, are interested in, my way using \u202E unicode is here.

public static String reverse(String s) {
        return "\u202E" + s;
}

It can be tested from here.

It is just to print. If your aim is to pass a string in a reversed manner, you need to do it using loop or recursion.

This is an issue relating JRE.In my case (eclipse Luna with Maven plugin, JDK 7) I solved this by making following change in pom.xml and then Maven Update Project.

In case anyone has the same problem in the future:

$ adb shell
$ su
# mount -o rw,remount /system

Both adb remount and adb root don't work on a production build without altering ro.secure, but you can still remount /system by opening a shell, asking for root permissions and typing the mount command.

This is how:

[November 2020 Update: This solution relies on being able to set document.domain. The ability to do that has now been deprecated, unfortunately.]

For sharing between subdomains of a given superdomain (e.g. example.com), there's a technique you can use in that situation. It can be applied to localStorage, IndexedDB, SharedWorker, BroadcastChannel, etc, all of which offer shared functionality between same-origin pages, but for some reason don't respect any modification to document.domain that would let them use the superdomain as their origin directly.

(1) Pick one "main" domain to for the data to belong to: i.e. either https://example.com or https://www.example.com will hold your localStorage data. Let's say you pick https://example.com.

(2) Use localStorage normally for that chosen domain's pages.

(3) On all https://www.example.com pages (the other domain), use javascript to set document.domain = "example.com";. Then also create a hidden <iframe>, and navigate it to some page on the chosen https://example.com domain (It doesn't matter what page, as long as you can insert a very little snippet of javascript on there. If you're creating the site, just make an empty page specifically for this purpose. If you're writing an extension or a Greasemonkey-style userscript and so don't have any control over pages on the example.com server, just pick the most lightweight page you can find and insert your script into it. Some kind of "not found" page would probably be fine).

(4) The script on the hidden iframe page need only (a) set document.domain = "example.com";, and (b) notify the parent window when this is done. After that, the parent window can access the iframe window and all its objects without restriction! So the minimal iframe page is something like:

<!doctype html>
<html>
<head>
  <script>
    document.domain = "example.com";
    window.parent.iframeReady();  // function defined & called on parent window
  </script>
</head>
<body></body>
</html>

If writing a userscript, you might not want to add externally-accessible functions such as iframeReady() to your unsafeWindow, so instead a better way to notify the main window userscript might be to use a custom event:

    window.parent.dispatchEvent(new CustomEvent("iframeReady"));

Which you'd detect by adding a listener for the custom "iframeReady" event to your main page's window.

(NOTE: You need to set document.domain = "example.com" even if the iframe's domain is already example.com: Assigning a value to document.domain implicitly sets the origin's port to null, and both ports must match for the iframe and its parent to be considered same-origin. See the note here: https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy#Changing_origin)

(5) Once the hidden iframe has informed its parent window that it's ready, script in the parent window can just use iframe.contentWindow.localStorage, iframe.contentWindow.indexedDB, iframe.contentWindow.BroadcastChannel, iframe.contentWindow.SharedWorker instead of window.localStorage, window.indexedDB, etc. ...and all these objects will be scoped to the chosen https://example.com origin - so they'll have the this same shared origin for all of your pages!

The most awkward part of this technique is that you have to wait for the iframe to load before proceeding. So you can't just blithely start using localStorage in your DOMContentLoaded handler, for example. Also you might want to add some error handling to detect if the hidden iframe fails to load correctly.

Obviously, you should also make sure the hidden iframe is not removed or navigated during the lifetime of your page... OTOH I don't know what the result of that would be, but very likely bad things would happen.

And, a caveat: setting/changing document.domain can be blocked using the Feature-Policy header, in which case this technique will not be usable as described.

However, there is a significantly more-complicated generalization of this technique, that can't be blocked by Feature-Policy, and that also allows entirely unrelated domains to share data, communications, and shared workers (i.e. not just subdomains off a common superdomain). @Mayank Jain already described it in their answer, namely:

The general idea is that, just as above, you create a hidden iframe to provide the correct origin for access; but instead of then just grabbing the iframe window's properties directly, you use script inside the iframe to do all of the work, and you communicate between the iframe and your main window only using postMessage() and addEventListener("message",...).

This works because postMessage() can be used even between different-origin windows. But it's also significantly more complicated because you have to pass everything through some kind of messaging infrastructure that you create between the iframe and the main window, rather than just using the localStorage, IndexedDB, etc. APIs directly in your main window's code.

Here’s some PHP and JavaScript demonstration code that shows a simple way to create indexed fields on a form (fields that have the same name) and then process them in both JavaScript and PHP. The fields must have both "ID" names and "NAME" names. Javascript uses the ID and PHP uses the NAME.

<?php
// How to use same field name multiple times on form
// Process these fields in Javascript and PHP
// Must use "ID" in Javascript and "NAME" in PHP 
echo "<HTML>";
echo "<HEAD>";
?>
<script type="text/javascript">
function TestForm(form) {
// Loop through the HTML form field (TheId) that is returned as an array. 
// The form field has multiple (n) occurrences on the form, each which has the same name.
// This results in the return of an array of elements indexed from 0 to n-1.
// Use ID  in Javascript
var i = 0;
document.write("<P>Javascript responding to your button click:</P>");
for (i=0; i < form.TheId.length; i++) {
  document.write(form.TheId[i].value);
  document.write("<br>");
}  
}
</script>
<?php
echo "</HEAD>";
echo "<BODY>";
$DQ = '"';  # Constant for building string with double quotes in it.

if (isset($_POST["MyButton"])) {
  $TheNameArray = $_POST["TheName"];  # Use NAME in PHP
  echo "<P>Here are the names you submitted to server:</P>";
  for ($i = 0; $i <3; $i++) {   
    echo $TheNameArray[$i] . "<BR>";
  } 
}
echo "<P>Enter names and submit to server or Javascript</P>";
echo "<FORM NAME=TstForm METHOD=POST ACTION=" ;
echo $DQ . "TestArrayFormToJavascript2.php" . $DQ . "OnReset=" . $DQ . "return allowreset(this)" . $DQ . ">";
echo "<FORM>";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<P><INPUT TYPE=submit NAME=MyButton VALUE=" . $DQ . "Submit to server"    . $DQ . "></P>";
echo "<P><BUTTON onclick=" . $DQ . "TestForm(this.form)" . $DQ . ">Submit to Javascript</BUTTON></P>"; 
echo "</FORM>";
echo "</BODY>";
echo "</HTML>";

The find command will take long time because it scans real files in file system.

The quickest way is using locate command, which will give result immediately:

locate "John"

If the command is not found, you need to install mlocate package and run updatedb command first to prepare the search database for the first time.

fedorqui has a working solution but there is another way to do the same thing.

Chock if a variable is set

#!/bin/bash
amIEmpty='Hello'
# This will be true if the variable has a value
if [ $amIEmpty ]; then
    echo 'No, I am not!';
fi

Or to verify that a variable is empty

#!/bin/bash      
amIEmpty=''
# This will be true if the variable is empty
if [ ! $amIEmpty ]; then
    echo 'Yes I am!';
fi

In a specific case the issue is due to the maven-archetype-webapp which is released for a dynamic webapp, faceted to the ver.2.5 (see the produced web.xml and the related xsd) and it's related to eclipse. When you try to change the project facet to dynamic webapp > 2.5 the src folder structure will syntactically change (the 2.5 is different from 3.1), but not fisically.

This is why you will face in a null pointer exception if you apply to the changes.

To solve it you have to set from the project facets configuration the Default configuration. Apply the changes, then going into the Java Build Path you have to remove the /src folder and create the /src/main/java folder at least (it's also required /src/main/resources and /src/test/java to be compliant) re-change into the required configuration you desire (3.0, 3.1) and then do apply.

SELECT * FROM sys.objects WHERE type='p' ORDER BY modify_date DESC

SELECT name, create_date, modify_date 
FROM sys.objects
WHERE type = 'P'

SELECT name, crdate, refdate 
FROM sysobjects
WHERE type = 'P' 
ORDER BY refdate desc

For the example you gave, use default values:

class City:
    def __init__(self, name="Default City Name"):
        ...
    ...

In general, you have two options:

1) Do if-elif blocks based on the type:

def __init__(self, name):
    if isinstance(name, str):
        ...
    elif isinstance(name, City):
        ...
    ...

2) Use duck typing --- that is, assume the user of your class is intelligent enough to use it correctly. This is typically the preferred option.

You can transfer array from javascript to PHP...

Javascript... ArraySender.html

<script language="javascript">

//its your javascript, your array can be multidimensional or associative

plArray = new Array();
plArray[1] = new Array(); plArray[1][0]='Test 1 Data'; plArray[1][1]= 'Test 1'; plArray[1][2]= new Array();
plArray[1][2][0]='Test 1 Data Dets'; plArray[1][2][1]='Test 1 Data Info'; 
plArray[2] = new Array(); plArray[2][0]='Test 2 Data'; plArray[2][1]= 'Test 2';
plArray[3] = new Array(); plArray[3][0]='Test 3 Data'; plArray[3][1]= 'Test 3'; 
plArray[4] = new Array(); plArray[4][0]='Test 4 Data'; plArray[4][1]= 'Test 4'; 
plArray[5] = new Array(); plArray[5]["Data"]='Test 5 Data'; plArray[5]["1sss"]= 'Test 5'; 

function convertJsArr2Php(JsArr){
    var Php = '';
    if (Array.isArray(JsArr)){  
        Php += 'array(';
        for (var i in JsArr){
            Php += '\'' + i + '\' => ' + convertJsArr2Php(JsArr[i]);
            if (JsArr[i] != JsArr[Object.keys(JsArr)[Object.keys(JsArr).length-1]]){
                Php += ', ';
            }
        }
        Php += ')';
        return Php;
    }
    else{
        return '\'' + JsArr + '\'';
    }
}


function ajaxPost(str, plArrayC){
    var xmlhttp;
    if (window.XMLHttpRequest){xmlhttp = new XMLHttpRequest();}
    else{xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");}
    xmlhttp.open("POST",str,true);
    xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    xmlhttp.send('Array=' + plArrayC);
}

ajaxPost('ArrayReader.php',convertJsArr2Php(plArray));
</script>

and PHP Code... ArrayReader.php

<?php 

eval('$plArray = ' . $_POST['Array'] . ';');
print_r($plArray);

?>

One line solution:

eval `python -c 'import sysconfig;print("python_include_path={0}".format(sysconfig.get_path("include")))'`
echo $python_include_path  # prints /home/<usr>/anaconda3/include/python3.6m" in my case

Breakdown:

Python call

python -c 'import sysconfig;print("python_include_path={0}".format(sysconfig.get_path("include")))'

It's launching a python script that

1. imports sysconfig
2. gets the python include path corresponding to this python binary (use "which python" to see which one is being used)
3. prints the script "python_include_path={0}" with {0} being the path from 2

Eval call

eval `python -c 'import sysconfig;print("python_include_path={0}".format(sysconfig.get_path("include")))'`

It's executing in the current bash instance the output from the python script. In my case, its executing:

python_include_path=/home/<usr>/anaconda3/include/python3.6m

In other words, it's setting the environment variable "python_include_path" with that path for this shell instance.

The modern way to do this is with flexbox, adding align-items: flex-end; on the container.

With this content:

<div class="Container">
  <div>one</div>
  <div>two</div>
</div>

Use this style:

.Container {
  display: flex;
  align-items: flex-end;
}

Inner join.

A join is combining the rows from two tables. An inner join attempts to match up the two tables based on the criteria you specify in the query, and only returns the rows that match. If a row from the first table in the join matches two rows in the second table, then two rows will be returned in the results. If there’s a row in the first table that doesn’t match a row in the second, it’s not returned; likewise, if there’s a row in the second table that doesn’t match a row in the first, it’s not returned.

Outer Join.

A left join attempts to find match up the rows from the first table to rows in the second table. If it can’t find a match, it will return the columns from the first table and leave the columns from the second table blank (null).

the problem can because of MVC MW.you must set formatterType in MVC options:

services.AddMvc(options =>
            {
                options.UseCustomStringModelBinder();
                options.AllowEmptyInputInBodyModelBinding = true;
                foreach (var formatter in options.InputFormatters)
                {
                    if (formatter.GetType() == typeof(SystemTextJsonInputFormatter))
                        ((SystemTextJsonInputFormatter)formatter).SupportedMediaTypes.Add(
                            Microsoft.Net.Http.Headers.MediaTypeHeaderValue.Parse("text/plain"));
                }
            }).AddJsonOptions(options =>
            {
                options.JsonSerializerOptions.PropertyNameCaseInsensitive = true;
            });

split returns an Iterator, which you can convert into a Vec using collect: split_line.collect::<Vec<_>>(). Going through an iterator instead of returning a Vec directly has several advantages:

• split is lazy. This means that it won't really split the line until you need it. That way it won't waste time splitting the whole string if you only need the first few values: split_line.take(2).collect::<Vec<_>>(), or even if you need only the first value that can be converted to an integer: split_line.filter_map(|x| x.parse::<i32>().ok()).next(). This last example won't waste time attempting to process the "23.0" but will stop processing immediately once it finds the "1".
• split makes no assumption on the way you want to store the result. You can use a Vec, but you can also use anything that implements FromIterator<&str>, for example a LinkedList or a VecDeque, or any custom type that implements FromIterator<&str>.
