It is just a hint for the Service Provider on what to expect from the NameID returned by the Identity Provider. It can be:

1. unspecified
2. emailAddress – e.g. [email protected]
3. X509SubjectName – e.g. CN=john,O=Company Ltd.,C=US
4. WindowsDomainQualifiedName – e.g. CompanyDomain\John
5. kerberos– e.g. john@realm
6. entity – this one in used to identify entities that provide SAML-based services and looks like a URI
7. persistent – this is an opaque service-specific identifier which must include a pseudo-random value and must not be traceable to the actual user, so this is a privacy feature.
8. transient – opaque identifier which should be treated as temporary.

For a line-by-line delta measurement, try gnomon.

A command line utility, a bit like moreutils's ts, to prepend timestamp information to the standard output of another command. Useful for long-running processes where you'd like a historical record of what's taking so long.

You can also use the --high and/or --medium options to specify a length threshold in seconds, over which gnomon will highlight the timestamp in red or yellow. And you can do a few other things, too.

You can try my suggestion for a work around in Doug's approach.
But if you want to stick with your logic though, you can try this:

Option Explicit

Sub GetUnique()

Dim rng As Range
Dim myarray, myunique
Dim i As Integer

ReDim myunique(1)

With ThisWorkbook.Sheets("Sheet1")
    Set rng = .Range(.Range("A1"), .Range("A" & .Rows.Count).End(xlUp))
    myarray = Application.Transpose(rng)
    For i = LBound(myarray) To UBound(myarray)
        If IsError(Application.Match(myarray(i), myunique, 0)) Then
            myunique(UBound(myunique)) = myarray(i)
            ReDim Preserve myunique(UBound(myunique) + 1)
        End If
    Next
End With

For i = LBound(myunique) To UBound(myunique)
    Debug.Print myunique(i)
Next

End Sub

This uses array instead of range.
It also uses Match function instead of a nested For Loop.
I didn't have the time to check the time difference though.
So I leave the testing to you.

Here are few steps that must be followed carefully

1. First of all make sure that the WAMP server is running if it is not running, start the server.
2. Enter the URL http://localhost/phpmyadmin/setup in address bar of your browser.

3. Create a folder named config inside C:\wamp\apps\phpmyadmin, the folder inside apps may have different name like phpmyadmin3.2.0.1

4. Return to your browser in phpmyadmin setup tab, and click New server.

5. Change the authentication type to ‘cookie’ and leave the username and password field empty but if you change the authentication type to ‘config’ enter the password for username root.

6. Click save

7. Again click save in configuration file option.
8. Now navigate to the config folder. Inside the folder there will be a file named config.inc.php. Copy the file and paste it out of the folder (if the file with same name is already there then override it) and finally delete the folder.
9. Now you are done. Try to connect the mysql server again and this time you won’t get any error. --credits Bibek Subedi

From the HashSet<T> page on MSDN:

The HashSet(Of T) class provides high-performance set operations. A set is a collection that contains no duplicate elements, and whose elements are in no particular order.

(emphasis mine)

What you need, according to your comments, is a 'BLOB' (Binary Large OBject) for both image and resume.

bool b = list.Contains("Hello", StringComparer.CurrentCultureIgnoreCase);

[EDIT] extension code:

public static bool Contains(this string source, string cont
                                                    , StringComparison compare)
{
    return source.IndexOf(cont, compare) >= 0;
}

This could work :)

Instance variable is the variable declared inside a class, but outside a method: something like:

class IronMan {

    /** These are all instance variables **/
    public String realName;
    public String[] superPowers;
    public int age;

    /** Getters and setters here **/
}

Now this IronMan Class can be instantiated in another class to use these variables. Something like:

class Avengers {

    public static void main(String[] a) {
        IronMan ironman = new IronMan();
        ironman.realName = "Tony Stark";
        // or
        ironman.setAge(30);
    }

}

This is how we use the instance variables. Shameless plug: This example was pulled from this free e-book here here.

It depends on what you're wanting to use it for. If you're just trying to save it, you should use pickle (or, if you’re using CPython 2.x, cPickle, which is faster).

>>> import pickle
>>> pickle.dumps({'foo': 'bar'})
b'\x80\x03}q\x00X\x03\x00\x00\x00fooq\x01X\x03\x00\x00\x00barq\x02s.'
>>> pickle.loads(_)
{'foo': 'bar'}

If you want it to be readable, you could use json:

>>> import json
>>> json.dumps({'foo': 'bar'})
'{"foo": "bar"}'
>>> json.loads(_)
{'foo': 'bar'}

json is, however, very limited in what it will support, while pickle can be used for arbitrary objects (if it doesn't work automatically, the class can define __getstate__ to specify precisely how it should be pickled).

>>> pickle.dumps(object())
b'\x80\x03cbuiltins\nobject\nq\x00)\x81q\x01.'
>>> json.dumps(object())
Traceback (most recent call last):
  ...
TypeError: <object object at 0x7fa0348230c0> is not JSON serializable

A small note about the efficiency of abovementioned methods:

 library(microbenchmark)

  microbenchmark(
    which("Feb" == month.abb)[[1]],
    which(month.abb %in% "Feb"))

  Unit: nanoseconds
   min     lq    mean median     uq  max neval
   891  979.0 1098.00   1031 1135.5 3693   100
   1052 1175.5 1339.74   1235 1390.0 7399  100

So, the best one is

    which("Feb" == month.abb)[[1]]

I just recently had the same problem.

I managed to solve it with two absolutely positioned divs carrying the border (one for horizontal and one for vertical), and then transforming them. The outer box just needs to be relatively positioned.

<div class="relative">
    <div class="absolute absolute--fill overflow-hidden">
        <div class="absolute absolute--fill b--dashed b--red"
            style="
                border-width: 4px 0px 4px 0px;
                transform: scaleX(2);
        "></div>
        <div class="absolute absolute--fill b--dashed b--red"
            style="
                border-width: 0px 4px 0px 4px;
                transform: scaleY(2);
        "></div>
    </div>

    <div> {{Box content goes here}} </div>
</div>

Note: i used tachyons in this example, but i guess the classes are kind of self-explanatory.

Here is the Best Option for Dynamic className , just do some concatenation like we do in Javascript.

     className={
        "badge " +
        (this.state.value ? "badge-primary " : "badge-danger ") +
        " m-4"
      }

change the port may help as 80 port is already using somewhere

vi /etc/nginx/sites-available/default

Change the port:

listen 8080 default_server;
listen [::]:8080 default_server;

And then restart the nginx server

nginx -t
service nginx restart

here is mine

echo Math+ 
ECHO First num:
 SET /P a= 
ECHO Second num:
 SET /P b=
 set /a s=%a%+%b% 
echo Result: %s%

You are missing the dot on the selector, and you can use toggleClass method on jquery:

$(".result").hover(
  function () {
    $(this).toggleClass("result_hover")      
  }
);

I've tested this using the following powershell script and using (,) between the addresses. It worked for me!

$EmailFrom = "<[email protected]>";
$EmailPassword = "<password>";
$EmailTo = "<[email protected]>,<[email protected]>";
$SMTPServer = "<smtp.server.com>";
$SMTPPort = <port>;
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer,$SMTPPort);
$SMTPClient.EnableSsl = $true;
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($EmailFrom, $EmailPassword);
$Subject = "Notification from XYZ";
$Body = "this is a notification from XYZ Notifications..";
$SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body);

String value = "True";
boolean result = value.equalsIgnoreCase("true") ? true : false;

Well there's always

assertThat(list.isEmpty(), is(false));

... but I'm guessing that's not quite what you meant :)

Alternatively:

assertThat((Collection)list, is(not(empty())));

empty() is a static in the Matchers class. Note the need to cast the list to Collection, thanks to Hamcrest 1.2's wonky generics.

The following imports can be used with hamcrest 1.3

import static org.hamcrest.Matchers.empty;
import static org.hamcrest.core.Is.is;
import static org.hamcrest.core.IsNot.*;

I started with the answer from Johndave Decano.

This should fix a few of the issues mentioned in replies to his function.

1. Replace %20 with a + symbol.
2. Submit/Button types will only be submitted if they were clicked to submit the form.
3. Reset buttons will be ignored.
4. The code seemed redundant to me since it is doing essentially the same thing regardless of the field types. Not to mention incompatibility with HTML5 field types such as 'tel' and 'email', thus I removed most of the specifics with the switch statements.

Button types will still be ignored if they don't have a name value.

function serialize(form, evt){
    var evt    = evt || window.event;
    evt.target = evt.target || evt.srcElement || null;
    var field, query='';
    if(typeof form == 'object' && form.nodeName == "FORM"){
        for(i=form.elements.length-1; i>=0; i--){
            field = form.elements[i];
            if(field.name && field.type != 'file' && field.type != 'reset'){
                if(field.type == 'select-multiple'){
                    for(j=form.elements[i].options.length-1; j>=0; j--){
                        if(field.options[j].selected){
                            query += '&' + field.name + "=" + encodeURIComponent(field.options[j].value).replace(/%20/g,'+');
                        }
                    }
                }
                else{
                    if((field.type != 'submit' && field.type != 'button') || evt.target == field){
                        if((field.type != 'checkbox' && field.type != 'radio') || field.checked){
                            query += '&' + field.name + "=" + encodeURIComponent(field.value).replace(/%20/g,'+');
                        }   
                    }
                }
            }
        }
    }
    return query.substr(1);
}

This is how I am currently using this function.

<form onsubmit="myAjax('http://example.com/services/email.php', 'POST', serialize(this, event))">

Menu Window ? Preferences. General ? Appearance ? Colors and Fonts ? Basic ? Text Font

For HTML5:

Simply add to your <head>

 <meta charset="UTF-8"> 

An example usage:

>>> s = 'Hello world'
>>> t = buffer(s, 6, 5)
>>> t
<read-only buffer for 0x10064a4b0, size 5, offset 6 at 0x100634ab0>
>>> print t
world

The buffer in this case is a sub-string, starting at position 6 with length 5, and it doesn't take extra storage space - it references a slice of the string.

This isn't very useful for short strings like this, but it can be necessary when using large amounts of data. This example uses a mutable bytearray:

>>> s = bytearray(1000000)   # a million zeroed bytes
>>> t = buffer(s, 1)         # slice cuts off the first byte
>>> s[1] = 5                 # set the second element in s
>>> t[0]                     # which is now also the first element in t!
'\x05'

This can be very helpful if you want to have more than one view on the data and don't want to (or can't) hold multiple copies in memory.

Note that buffer has been replaced by the better named memoryview in Python 3, though you can use either in Python 2.7.

Note also that you can't implement a buffer interface for your own objects without delving into the C API, i.e. you can't do it in pure Python.

You need a special type of function known as a table valued function. Below is a somewhat long-winded example that builds a date dimension for a data warehouse. Note the returns clause that defines a table structure. You can insert anything into the table variable (@DateHierarchy in this case) that you want, including building a temporary table and copying the contents into it.

    drop function ods.uf_DateHierarchy
go

I'd suggest using wasabi then you can either use the markdown-ish feel like this

root/ # entry comments can be inline after a '#'
      # or on their own line, also after a '#'

  readme.md # a child of, 'root/', it's indented
            # under its parent.

  usage.md  # indented syntax is nice for small projects
            # and short comments.

  src/          # directories MUST be identified with a '/'
    fileOne.txt # files don't need any notation
    fileTwo*    # '*' can identify executables
    fileThree@  # '@' can identify symlinks

and throw that exact syntax at the js library for this

Opens a new window with the url you supplied :)

<button class="button" onClick="window.open('http://www.example.com');">
     <span class="icon">Open</span>
</button>

hope that helps :)

I encountered a similar problem using windows command line for R script, Rscript.exe, which is very sensitive to spaces in the path. The solution was to create a virtual path to the binary folder using the windows subst command.

The following fails: "C:\Program Files\R\R-3.4.0\bin\Rscript.exe"

Doing following succeeds:

subst Z: "C:\Program Files\R\R-3.4.0"
Z:\bin\Rscript.exe

The reason the above-proposed solutions didn't work, evidently, has to do with the Rscript.exe executable's own internal path resolution from its working directory (which has a space in it) rather the windows command line being confused with the space. So using ~ or " to resolve the issue at the command line is moot. The executable must be called within a path lacking spaces.

Setting Map Container to position to relative do the trick. Here is HTML.

<body>
    <!-- Map container -->
    <div id="map_canvas"></div>
</body>

And Simple CSS.

<style>
html, body, #map_canvas {
    width: 100%;
    height: 100%;
    margin: 0;
    padding: 0;
}
#map_canvas {
    position: relative;
}
</style>

Tested on all browsers. Here is the Screenshot.

return is part of a function definition, while print outputs text to the standard output (usually the console).

A function is a procedure accepting parameters and returning a value. return is for the latter, while the former is done with def.

Example:

def timestwo(x):
    return x*2

for root, dirs, files in os.walk(directory):
    for file in files:
        floc = file
        im = Image.open(str(directory) + '\\' + floc)
        pix = np.array(im.getdata())
        pixels.append(pix)
        labels.append(1)   # append(i)???

So far ok. But you want to leave pixels as a list until you are done with the iteration.

pixels = np.array(pixels)
labels = np.array(labels)

You had this indention right in your other question. What happened? previous

Iterating, collecting values in a list, and then at the end joining things into a bigger array is the right way. To make things clear I often prefer to use notation like:

alist = []
for ..
    alist.append(...)
arr = np.array(alist)

If names indicate something about the nature of the object I'm less likely to get errors like yours.

I don't understand what you are trying to do with traindata. I doubt if you need to build it during the loop. pixels and labels have the basic information.

That

traindata = np.array([traindata[i][i],traindata[1]], dtype=object)

comes from the previous question. I'm not sure you understand that answer.

traindata = []
traindata.append(pixels)
traindata.append(labels)

if done outside the loop is just

traindata = [pixels, labels]

labels is a 1d array, a bunch of 1s (or [0,1,2,3...] if my guess is right). pixels is a higher dimension array. What is its shape?

Stop right there. There's no point in turning that list into an array. You can save the list with pickle.

You are copying code from an earlier question, and getting the formatting wrong. cPickle very large amount of data

you need to parse your xml with jquery json parse...i.e

  var parsed_json = $.parseJSON(xml);

How about... It's like if you wanted to install a home theatre system in your house. Using an API is like getting all the wires, screws, bits, and pieces. The possibilities are endless (constrained only by the pieces you receive), but sometimes overwhelming. An SDK is like getting a kit. You still have to put it together, but it's more like getting pre-cut pieces and instructions for an IKEA bookshelf than a box of screws.

git log -1 branch_name will show you the last message from the specified branch (i.e. not necessarily the branch you're currently on).

Found a way, thanks to the link here (with the original google group discussion here)

First, Telnet to your server:

telnet 127.0.0.1 11211

Next, list the items to get the slab ids:

stats items
STAT items:3:number 1
STAT items:3:age 498
STAT items:22:number 1
STAT items:22:age 498
END

The first number after ‘items’ is the slab id. Request a cache dump for each slab id, with a limit for the max number of keys to dump:

stats cachedump 3 100
ITEM views.decorators.cache.cache_header..cc7d9 [6 b; 1256056128 s]
END

stats cachedump 22 100
ITEM views.decorators.cache.cache_page..8427e [7736 b; 1256056128 s]
END

This should work

import { Router } from "@angular/router"

export class YourClass{

   constructor(private router: Router) { }

   YourFunction() {
      this.router.navigate(['/path']);
   }

}

thanks to the answers of Steve Park and Rafal Borowiec I got my code working, however, I had one issue: the DriverManagerDataSource is a "simple" implementation and does NOT give you a ConnectionPool (check http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/jdbc/datasource/DriverManagerDataSource.html).

Hence, I replaced the functions which returns the DataSource for the secondDB to.

public DataSource <secondaryDB>DataSource() {
    // use DataSourceBuilder and NOT DriverManagerDataSource 
    // as this would NOT give you ConnectionPool
    DataSourceBuilder dataSourceBuilder = DataSourceBuilder.create();
    dataSourceBuilder.url(databaseUrl);
    dataSourceBuilder.username(username);
    dataSourceBuilder.password(password);
    dataSourceBuilder.driverClassName(driverClassName);
    return dataSourceBuilder.build();
}

Also, if do you not need the EntityManager as such, you can remove both the entityManager() and the @Bean annotation.

Plus, you may want to remove the basePackages annotation of your configuration class: maintaining it with the factoryBean.setPackagesToScan() call is sufficient.

You should use a StringBuilder:

StringBuilder contentBuilder = new StringBuilder();
try {
    BufferedReader in = new BufferedReader(new FileReader("mypage.html"));
    String str;
    while ((str = in.readLine()) != null) {
        contentBuilder.append(str);
    }
    in.close();
} catch (IOException e) {
}
String content = contentBuilder.toString();

You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save (or the before_validation) callback. Here's an example of the relevant code for a model like yours:

class Place < ActiveRecord::Base   before_save do |place|     place.city = place.city.downcase.titleize     place.country = place.country.downcase.titleize   end end 

You can also check out the Ruby on Rails guide for more info.

To answer you question more directly, something like this would work:

<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>   

This just means if f.object.city exists, display the titlecase version of it, and if it doesn't display a blank string.

You can use requests-html which will download and use chromium underneath.

from requests_html import HTML

html = HTML(html="<a href='http://www.example.com/'>")

script = """
function escramble_758(){
    var a,b,c
    a='+1 '
    b='84-'
    a+='425-'
    b+='7450'
    c='9'
    return a+c+b;
}
"""

val = html.render(script=script, reload=False)
print(val)
# +1 425-984-7450

Duplicate the string, tokenize it, then free it.

free(dup);

ipWebCode = urllib.request.urlopen("http://ip.nefsc.noaa.gov").read().decode("utf8")
ipWebCode=ipWebCode.split("color=red> ")
ipWebCode = ipWebCode[1]
ipWebCode = ipWebCode.split("</font>")
externalIp = ipWebCode[0]

this is a short snippet I had written for another program. The trick was finding a simple enough website so that dissecting the html wasn't a pain.

In simple words

$.ajax("info.txt").done(function(data) {
  alert(data);
}).fail(function(data){
  alert("Try again champ!");
});

if its get the info.text then it will alert and whatever function you add or if any how unable to retrieve info.text from the server then alert or error function.

The HTML should look like:

<div class="solTitle"> <a href="#"  id="solution0">Solution0 </a></div>
<div class="solTitle"> <a href="#"  id="solution1">Solution1 </a></div>

<div id="summary_solution0" style="display:none" class="summary">Summary solution0</div>
<div id="summary_solution1" style="display:none" class="summary">Summary solution1</div>

And the javascript:

$(document).ready(function(){
    $(".solTitle a").live('click',function(e){
        var contentId = "summary_" + $(this).attr('id');
        $(".summary").hide();
        $("#" + contentId).show();
    });
});

See the Example: http://jsfiddle.net/kmendes/4G9UF/

In general, you're looking for the "Except" extension.

var rejectStatus = GenerateRejectStatuses();
var fullList = GenerateFullList();
var rejectList = fullList.Where(i => rejectStatus.Contains(i.Status));
var filteredList = fullList.Except(rejectList);

In this example, GenerateRegectStatuses() should be the list of statuses you wish to reject (or in more concrete terms based on your example, a List<int> of IDs)

I needed the list indices that correspond to a match as follows:

lst=['abc-123', 'def-456', 'ghi-789', 'abc-456']

[n for n, x in enumerate(lst) if 'abc' in x]

output

[0, 3]

Celery is a distributed task queue, built on AMQP (RabbitMQ). It also handles periodic tasks in a cron-like fashion (see periodic tasks). Depending on your app, it might be worth a gander.

Celery is pretty easy to set up with django (docs), and periodic tasks will actually skip missed tasks in case of a downtime. Celery also has built-in retry mechanisms, in case a task fails.

Based on Mark's answer above (and Geo's comment), I created a two liner version to remove all ASCII exception cases from a string. Provided for people searching for this answer (as I did).

using System.Text;

// Create encoder with a replacing encoder fallback
var encoder = ASCIIEncoding.GetEncoding("us-ascii", 
    new EncoderReplacementFallback(string.Empty), 
    new DecoderExceptionFallback());

string cleanString = encoder.GetString(encoder.GetBytes(dirtyString)); 

From the docs

In the Java programming language, every application must contain a main method whose signature is:

public static void main(String[] args)

The modifiers public and static can be written in either order (public static or static public), but the convention is to use public static as shown above. You can name the argument anything you want, but most programmers choose "args" or "argv".

As you say:

error: missing method body, or declare abstract public static void main(String[] args); ^ this is what i got after i added it after the class name

You probably haven't declared main with a body (as ';" would suggest in your error).

You need to have main method with a body, which means you need to add { and }:

public static void main(String[] args) {


}

Add it inside your class definition.

Although sometimes error messages are not very clear, most of the time they contain enough information to point to the issue. Worst case, you can search internet for the error message. Also, documentation can be really helpful.

Convert interface{} into any type.

Syntax:

result := interface.(datatype)

Example:

var employee interface{} = []string{"Jhon", "Arya"}
result := employee.([]string)   //result type is []string.

By default reference types have reference equality (i.e. two instances are only equal if they are the same object).

You need to override Object.Equals (and Object.GetHashCode to match) to implement your own equality. (And it is then good practice to implement an equality, ==, operator.)

I open a text editor, in my case I used Atom. Paste this code

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');

and save as

helloworld.js

in

c:\xampp\htdocs\myproject 

directory. Next I open node.js commamd prompt enter

cd c:\xampp\htdocs\myproject

next

node helloworld.js

next I open my chrome browser and I type

http://localhost:1337

and there it is.

When you use the start command to a website it will use the default browser by default but if you want to use a specific browser then use start iexplorer.exe www.website.com

Also you cannot have http:// in the url.

I come from a stripped down KDE background and do not have access to xclip, xsel or the other fancy stuff. I have a TCSH Konsole to make matters worse.

Requisites: qdbus klipper xargs bash

Create a bash executable foo.sh.

#!/bin/bash
qdbus org.kde.klipper /klipper setClipboardContents "$1" > /dev/null

Note: This needs to be bash as TCSH does not support multi-line arguments.

Followed by a TCSH alias in the.cshrc.

alias clipboard xargs -0 /path/to/foo

Explanation:

xargs -0 pipes stdin into a single argument. This argument is passed to the bash executable which sends a "copy to clipboard" request to klipper using qdbus. The pipe to /dev/null is to not print the newline character returned by qdbus to the console.

Example Usage:

ls | clipboard

This copies the contents of the current folder into the clipboard.

Note: Only works as a pipe. Use the bash executable directly if you need to copy an argument.

You can reference an aar file from a repository. A maven is an option, but there is a simpler solution: put the aar file in your libs directory and add a directory repository.

    repositories {
      mavenCentral()
      flatDir {
        dirs 'libs'
      }
    }

Then reference the library in the dependency section:

  dependencies {
        implementation 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'
}

You can check out Min'an blog post for more info.

This is what SSMS uses when you script using the DROP and CREATE option

IF EXISTS (SELECT *
           FROM   sys.objects
           WHERE  object_id = OBJECT_ID(N'[dbo].[foo]')
                  AND type IN ( N'FN', N'IF', N'TF', N'FS', N'FT' ))
  DROP FUNCTION [dbo].[foo]

GO 

This approach to deploying changes means that you need to recreate all permissions on the object so you might consider ALTER-ing if Exists instead.

You can use attribute selectors but they won't work in IE6 like meder said, there are javascript workarounds to that tho. Check Selectivizr

After making your corrections listed in the top answer, change the default settings of your server.

In your "/etc/my.cnf.d/server.cnf" or where ever it's located add the defaults to the [mysqld] section so it looks like this:

[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci

If you are using MasterPages and Content pages in your app - you also have the option of putting the ScriptManager on the Masterpage and then every ContentPage that uses that MasterPage will NOT need a script manager added. If you need some of the special configurations of the ScriptManager - like javascript file references - you can use a ScriptManagerProxy control on the content page that needs it.

This solution worked for MacOS Sierra, and running MySQL version 8.0.11. Please make sure driver you have added in your build path - "add external jar" should match up with SQL version.

Consider this simple problem:

class Number:

    def __init__(self, number):
        self.number = number


n1 = Number(1)
n2 = Number(1)

n1 == n2 # False -- oops

So, Python by default uses the object identifiers for comparison operations:

id(n1) # 140400634555856
id(n2) # 140400634555920

Overriding the __eq__ function seems to solve the problem:

def __eq__(self, other):
    """Overrides the default implementation"""
    if isinstance(other, Number):
        return self.number == other.number
    return False


n1 == n2 # True
n1 != n2 # True in Python 2 -- oops, False in Python 3

In Python 2, always remember to override the __ne__ function as well, as the documentation states:

There are no implied relationships among the comparison operators. The truth of x==y does not imply that x!=y is false. Accordingly, when defining __eq__(), one should also define __ne__() so that the operators will behave as expected.

def __ne__(self, other):
    """Overrides the default implementation (unnecessary in Python 3)"""
    return not self.__eq__(other)


n1 == n2 # True
n1 != n2 # False

In Python 3, this is no longer necessary, as the documentation states:

By default, __ne__() delegates to __eq__() and inverts the result unless it is NotImplemented. There are no other implied relationships among the comparison operators, for example, the truth of (x<y or x==y) does not imply x<=y.

But that does not solve all our problems. Let’s add a subclass:

class SubNumber(Number):
    pass


n3 = SubNumber(1)

n1 == n3 # False for classic-style classes -- oops, True for new-style classes
n3 == n1 # True
n1 != n3 # True for classic-style classes -- oops, False for new-style classes
n3 != n1 # False

Note: Python 2 has two kinds of classes:

• classic-style (or old-style) classes, that do not inherit from object and that are declared as class A:, class A(): or class A(B): where B is a classic-style class;

• new-style classes, that do inherit from object and that are declared as class A(object) or class A(B): where B is a new-style class. Python 3 has only new-style classes that are declared as class A:, class A(object): or class A(B):.

For classic-style classes, a comparison operation always calls the method of the first operand, while for new-style classes, it always calls the method of the subclass operand, regardless of the order of the operands.

So here, if Number is a classic-style class:

• n1 == n3 calls n1.__eq__;
• n3 == n1 calls n3.__eq__;
• n1 != n3 calls n1.__ne__;
• n3 != n1 calls n3.__ne__.

And if Number is a new-style class:

• both n1 == n3 and n3 == n1 call n3.__eq__;
• both n1 != n3 and n3 != n1 call n3.__ne__.

To fix the non-commutativity issue of the == and != operators for Python 2 classic-style classes, the __eq__ and __ne__ methods should return the NotImplemented value when an operand type is not supported. The documentation defines the NotImplemented value as:

Numeric methods and rich comparison methods may return this value if they do not implement the operation for the operands provided. (The interpreter will then try the reflected operation, or some other fallback, depending on the operator.) Its truth value is true.

In this case the operator delegates the comparison operation to the reflected method of the other operand. The documentation defines reflected methods as:

There are no swapped-argument versions of these methods (to be used when the left argument does not support the operation but the right argument does); rather, __lt__() and __gt__() are each other’s reflection, __le__() and __ge__() are each other’s reflection, and __eq__() and __ne__() are their own reflection.

The result looks like this:

def __eq__(self, other):
    """Overrides the default implementation"""
    if isinstance(other, Number):
        return self.number == other.number
    return NotImplemented

def __ne__(self, other):
    """Overrides the default implementation (unnecessary in Python 3)"""
    x = self.__eq__(other)
    if x is NotImplemented:
        return NotImplemented
    return not x

Returning the NotImplemented value instead of False is the right thing to do even for new-style classes if commutativity of the == and != operators is desired when the operands are of unrelated types (no inheritance).

Are we there yet? Not quite. How many unique numbers do we have?

len(set([n1, n2, n3])) # 3 -- oops

Sets use the hashes of objects, and by default Python returns the hash of the identifier of the object. Let’s try to override it:

def __hash__(self):
    """Overrides the default implementation"""
    return hash(tuple(sorted(self.__dict__.items())))

len(set([n1, n2, n3])) # 1

The end result looks like this (I added some assertions at the end for validation):

class Number:

    def __init__(self, number):
        self.number = number

    def __eq__(self, other):
        """Overrides the default implementation"""
        if isinstance(other, Number):
            return self.number == other.number
        return NotImplemented

    def __ne__(self, other):
        """Overrides the default implementation (unnecessary in Python 3)"""
        x = self.__eq__(other)
        if x is not NotImplemented:
            return not x
        return NotImplemented

    def __hash__(self):
        """Overrides the default implementation"""
        return hash(tuple(sorted(self.__dict__.items())))


class SubNumber(Number):
    pass


n1 = Number(1)
n2 = Number(1)
n3 = SubNumber(1)
n4 = SubNumber(4)

assert n1 == n2
assert n2 == n1
assert not n1 != n2
assert not n2 != n1

assert n1 == n3
assert n3 == n1
assert not n1 != n3
assert not n3 != n1

assert not n1 == n4
assert not n4 == n1
assert n1 != n4
assert n4 != n1

assert len(set([n1, n2, n3, ])) == 1
assert len(set([n1, n2, n3, n4])) == 2

Perhaps to late to the party, but you could just do the following:

const set = new Set(['a', 'b']);
const values = set.values();
const array = Array.from(values);

This should work without problems in browsers that have support for ES6 or if you have a shim that correctly polyfills the above functionality.

Edit: Today you can just use what @c69 suggests:

const set = new Set(['a', 'b']);
const array = [...set]; // or Array.from(set)

This ensures that resolution occurs from the global namespace, instead of starting at the namespace you're currently in. For instance, if you had two different classes called Configuration as such:

class Configuration; // class 1, in global namespace
namespace MyApp
{
    class Configuration; // class 2, different from class 1
    function blah()
    {
        // resolves to MyApp::Configuration, class 2
        Configuration::doStuff(...) 
        // resolves to top-level Configuration, class 1
        ::Configuration::doStuff(...)
    }
}

Basically, it allows you to traverse up to the global namespace since your name might get clobbered by a new definition inside another namespace, in this case MyApp.

If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?

public static class ErrorCode
{
    public const IDictionary<string , string > m_ErrorCodeDic;

    public static ErrorCode()
    {
      m_ErrorCodeDic = new Dictionary<string, string>()
             { {"1","User name or password problem"} };             
    }
}

Probably initialise in the constructor.

Thrilling experiments done here, and more thrilling explanations by Tom

As of Xcode 8 Objective-C now supports class properties:

@interface MyClass : NSObject
@property (class, nonatomic, assign, readonly) NSUUID* identifier;
@end

Since class properties are never synthesised you need to write your own implementation.

@implementation MyClass
static NSUUID*_identifier = nil;

+ (NSUUID *)identifier {
  if (_identifier == nil) {
    _identifier = [[NSUUID alloc] init];
  }
  return _identifier;
}
@end

You access the class properties using normal dot syntax on the class name:

MyClass.identifier;

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill';

If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill'
  AND total = 203;

I know this is an old thread but I think the Blaze library is worth checking out. It's built for these types of situations.

From the docs:

Blaze extends the usability of NumPy and Pandas to distributed and out-of-core computing. Blaze provides an interface similar to that of the NumPy ND-Array or Pandas DataFrame but maps these familiar interfaces onto a variety of other computational engines like Postgres or Spark.

Edit: By the way, it's supported by ContinuumIO and Travis Oliphant, author of NumPy.

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

Where you want to set your location? you can use mapkit api to show u location's. see icodeblog.com for more detail on how to use mapkit. Also you can store your desired cordinates just create an object CLLocation2D *location; location.longitude=your desired longitude value; location.latitude=your desired latitude value;

For PHP 8+ we can omit the variable name for a caught exception.

As of PHP 8.0.0, the variable name for a caught exception is optional. If not specified, the catch block will still execute but will not have access to the thrown object.

And thus we can do it like this:

try {
  throw new Exception("An error");
}
catch (Exception) {}

If you don't need branch or tag name:
git log --oneline --graph --all --no-decorate

If you don't even need color (to avoid tty color sequence):
git log --oneline --graph --all --no-decorate --no-color

And a handy alias (in .gitconfig) to make life easier:

[alias]
  tree = log --oneline --graph --all --no-decorate

Only last option takes effect, so it's even possible to override your alias:
git tree --decorate

Answers provided here as which camera api to use are wrong. Or better to say they are insufficient.

Some phones (for example Samsung Galaxy S6) could be above api level 21 but still may not support Camera2 api.

CameraCharacteristics mCameraCharacteristics = mCameraManager.getCameraCharacteristics(mCameraId);
Integer level = mCameraCharacteristics.get(CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL);
if (level == null || level == CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY) {
    return false;
}

CameraManager class in Camera2Api has a method to read camera characteristics. You should check if hardware wise device is supporting Camera2 Api or not.

But there are more issues to handle if you really want to make it work for a serious application: Like, auto-flash option may not work for some devices or battery level of the phone might create a RuntimeException on Camera or phone could return an invalid camera id and etc.

So best approach is to have a fallback mechanism as for some reason Camera2 fails to start you can try Camera1 and if this fails as well you can make a call to Android to open default Camera for you.

Add this to your css file

.jumbotron {
    background-color:transparent !important; 
}

It worked for me.

However (if I do understand the difference between these methods right), only one thread is always selected for further monitor acquisition.

That is not correct. o.notifyAll() wakes all of the threads that are blocked in o.wait() calls. The threads are only allowed to return from o.wait() one-by-one, but they each will get their turn.

Simply put, it depends on why your threads are waiting to be notified. Do you want to tell one of the waiting threads that something happened, or do you want to tell all of them at the same time?

In some cases, all waiting threads can take useful action once the wait finishes. An example would be a set of threads waiting for a certain task to finish; once the task has finished, all waiting threads can continue with their business. In such a case you would use notifyAll() to wake up all waiting threads at the same time.

Another case, for example mutually exclusive locking, only one of the waiting threads can do something useful after being notified (in this case acquire the lock). In such a case, you would rather use notify(). Properly implemented, you could use notifyAll() in this situation as well, but you would unnecessarily wake threads that can't do anything anyway.

In many cases, the code to await a condition will be written as a loop:

synchronized(o) {
    while (! IsConditionTrue()) {
        o.wait();
    }
    DoSomethingThatOnlyMakesSenseWhenConditionIsTrue_and_MaybeMakeConditionFalseAgain();
}

That way, if an o.notifyAll() call wakes more than one waiting thread, and the first one to return from the o.wait() makes leaves the condition in the false state, then the other threads that were awakened will go back to waiting.

According to this article on sqlserverstudymaterial;

Remember that "%Privileged time" is not based on 100%.It is based on number of processors.If you see 200 for sqlserver.exe and the system has 8 CPU then CPU consumed by sqlserver.exe is 200 out of 800 (only 25%).

If "% Privileged Time" value is more than 30% then it's generally caused by faulty drivers or anti-virus software. In such situations make sure the BIOS and filter drives are up to date and then try disabling the anti-virus software temporarily to see the change.

If "% User Time" is high then there is something consuming of SQL Server. There are several known patterns which can be caused high CPU for processes running in SQL Server including

Assuming GNU tar (as this is Linux), the -T or --files-from option is what you want.

"Objects" are NEVER passed in C# -- "objects" are not values in the language. The only types in the language are primitive types, struct types, etc. and reference types. No "object types".

The types Object, MyClass, etc. are reference types. Their values are "references" -- pointers to objects. Objects can only be manipulated through references -- when you do new on them, you get a reference, the . operator operates on a reference; etc. There is no way to get a variable whose value "is" an object, because there are no object types.

All types, including reference types, can be passed by value or by reference. A parameter is passed by reference if it has a keyword like ref or out. The SetObject method's obj parameter (which is of a reference type) does not have such a keyword, so it is passed by value -- the reference is passed by value.

I added a "long" version to Leo Dabus's asnwer in case you want to have a string that says something like "2 weeks ago" instead of just "2w"...

Quote from the Spring reference doc:

Upon initialization of a DispatcherServlet, Spring MVC looks for a file named [servlet-name]-servlet.xml in the WEB-INF directory of your web application and creates the beans defined there...

Your servlet is called spring-dispatcher, so it looks for /WEB-INF/spring-dispatcher-servlet.xml. You need to have this servlet configuration, and define web related beans in there (like controllers, view resolvers, etc). See the linked documentation for clarification on the relation of servlet contexts to the global application context (which is the app-config.xml in your case).

One more thing, if you don't like the naming convention of the servlet config xml, you can specify your config explicitly:

<servlet>
    <servlet-name>spring-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

I would opt for NOT EXISTS in this case.

SELECT D1.ShortCode
FROM Domain1 D1
WHERE NOT EXISTS
    (SELECT 'X'
     FROM Domain2 D2
     WHERE D2.ShortCode = D1.ShortCode
    )

For those using the Symfony framework, the phpseclib can also be used to connect via SSH. It can be installed using composer:

composer require phpseclib/phpseclib

Next, simply use it as follows:

use phpseclib\Net\SSH2;

// Within a controller for example:
$ssh = new SSH2('hostname or ip');
if (!$ssh->login('username', 'password')) {
    // Login failed, do something
}

$return_value = $ssh->exec('command');

If you know you're always going to use bash, it's much easier to always use the double bracket conditional compound command [[ ... ]], instead of the Posix-compatible single bracket version [ ... ]. Inside a [[ ... ]] compound, word-splitting and pathname expansion are not applied to words, so you can rely on

if [[ $aug1 == "and" ]];

to compare the value of $aug1 with the string and.

If you use [ ... ], you always need to remember to double quote variables like this:

if [ "$aug1" = "and" ];

If you don't quote the variable expansion and the variable is undefined or empty, it vanishes from the scene of the crime, leaving only

if [ = "and" ]; 

which is not a valid syntax. (It would also fail with a different error message if $aug1 included white space or shell metacharacters.)

The modern [[ operator has lots of other nice features, including regular expression matching.

Please check you have two methods which has the different name and same parameters.

If so please delete any of the method and try.

Why not just select the Table and view the variable that way?

SELECT * FROM @d

You shouldn't include other source files (*.c) in .c files. I think you want to have a header (.h) file with the DECLARATION of test function, and have it's DEFINITION in a separate .c file.

The error is caused by multiple definitions of the test function (one in test.c and other in main.c)

Use CopyOnWriteArrayList
and if you want to remove it, do the following:

for (Iterator<String> it = userList.iterator(); it.hasNext() ;)
{
    if (wordsToRemove.contains(word))
    {
        it.remove();
    }
}

@kajetons' answer is fully functional.

You can also pass multiple variables by passing them like: use($var1, $var2)

DB::table('users')->where(function ($query) use ($activated,$var2) {
    $query->where('activated', '=', $activated);
    $query->where('var2', '>', $var2);
})->get();

you should add servler-api.jar file in WEB-INF/lib folder

This has probably been corrected, but... apparently firefox has a caching problem which is the cause of javascript functions not being recognized.. I really don't know the specifics, but if you clear your cache that will fix the problem (until your cache is full again... not a good solution).. I've been looking around to see if firefox has a real solution to this, but so far nothing... oh not all versions, I think it may be only in some 3.6.x versions, not sure...

Just a pointer: If you're calculating the difference between two java.util.Date the approach of subtracting both dates and dividing it by 1000 is reasonable, but take special care if you get your java.util.Date reference from a Calendar object. If you do so, you need to take account of daylight savings of your TimeZone since one of the dates you're using might take place on a DST period.

That is explained on Prasoon's link, I recommend taking some time to read it.

you can use simply write the code in a .bat format extension ,the code of the batch file :

c:/ copy /b Image1.jpg + Archive.rar Image2.jpg

use this c# code :

For Ubuntu 12.04.3 LTS (Precise Pangolin) I had to do:

apt-get install libxml2-dev libxslt1-dev

(Note the "1" in libxslt1-dev)

Then I just installed lxml with pip/easy_install.

If datasource is defined in application.resources, make sure it is locate right under src/main and add it to the build path.

You have to declare your functions before main()

(or declare the function prototypes before main())

As it is, the compiler sees my_print (my_string); in main() as a function declaration.

Move your functions above main() in the file, or put:

void my_print (char *);
void my_print2 (char *);

Above main() in the file.

By the way, in cstdlib there are __min and __max you can use.

As the other answers have mentioned, the int operation will crash if the string input is not convertible to an int (such as a float or characters). What you can do is use a little helper method to try and interpret the string for you:

def interpret_string(s):
    if not isinstance(s, basestring):
        return str(s)
    if s.isdigit():
        return int(s)
    try:
        return float(s)
    except ValueError:
        return s

So it will take a string and try to convert it to int, then float, and otherwise return string. This is more just a general example of looking at the convertible types. It would be an error for your value to come back out of that function still being a string, which you would then want to report to the user and ask for new input.

Maybe a variation that returns None if its neither float nor int:

def interpret_string(s):
    if not isinstance(s, basestring):
        return None
    if s.isdigit():
        return int(s)
    try:
        return float(s)
    except ValueError:
        return None

val=raw_input("> ")
how_much=interpret_string(val)
if how_much is None:
    # ask for more input? Error?

$servername = "localhost";

$username = "username";

$password = "password";

$dbname = "myDB";


// Create connection

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection

if ($conn->connect_error) {

die("Connection failed: " . $conn->connect_error);
}

$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', '[email protected]');";

$sql .= "INSERT INTO MyGuests (firstname, lastname, email)

$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Julie', 'Dooley', '[email protected]')";


 if ($conn->multi_query($sql) === TRUE) {

  echo "New records created successfully";

 } else {

   echo "Error: " . $sql . "<br>" . $conn->error;

}

$conn->close();

Is it possible to restart a single container

Not through kubectl, although depending on the setup of your cluster you can "cheat" and docker kill the-sha-goes-here, which will cause kubelet to restart the "failed" container (assuming, of course, the restart policy for the Pod says that is what it should do)

how do I restart the pod

That depends on how the Pod was created, but based on the Pod name you provided, it appears to be under the oversight of a ReplicaSet, so you can just kubectl delete pod test-1495806908-xn5jn and kubernetes will create a new one in its place (the new Pod will have a different name, so do not expect kubectl get pods to return test-1495806908-xn5jn ever again)

I think using dtype where there is a name row is confusing the routine. Try

In javascript, it is not possible but yes with the help of “Web Clips” we can create a "add to home screen" icon or shortcut in iPhone( by the code file of .mobileconfig)

https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/iPhoneOTAConfiguration/ConfigurationProfileExamples/ConfigurationProfileExamples.html

after create a mobileconfig file we can pass this url in iphone safari browser install certificate and after done it check your iphone home screen there is a shortcut icon of your Web page or webapp..

Update 2013: This code is obsolescent. Upvote bsb's late-coming answer instead.

I don't need to uninstall modules often, but the .packlist file based approach has never failed me so far.

use 5.010;
use ExtUtils::Installed qw();
use ExtUtils::Packlist qw();

die "Usage: $0 Module::Name Module::Name\n" unless @ARGV;

for my $mod (@ARGV) {
    my $inst = ExtUtils::Installed->new;

    foreach my $item (sort($inst->files($mod))) {
        say "removing $item";
        unlink $item or warn "could not remove $item: $!\n";
    }

    my $packfile = $inst->packlist($mod)->packlist_file;
    print "removing $packfile\n";
    unlink $packfile or warn "could not remove $packfile: $!\n";
}

You can also do this,

<?php 
if ( ($cart->count_product) > 0) { 
  $print .= "<div class='my_class'>"
  $print .= $cart->count_product; 
  $print .= "</div>"
} else { 
   $print = ''; 
} 
echo  $print;
?>

1. $() means: "first evaluate this, and then evaluate the rest of the line".

   Ex :

   echo $(pwd)/myFile.txt
   

   will be interpreted as

   echo /my/path/myFile.txt
   

   On the other hand ${} expands a variable.

   Ex:

   MY_VAR=toto
   echo ${MY_VAR}/myFile.txt
   

   will be interpreted as

   echo toto/myFile.txt
   

2. Why can't I use it as bash$ while ((i=0;i<10;i++)); do echo $i; done

   I'm afraid the answer is just that the bash syntax for while just isn't the same as the syntax for for.

As pointed by @ThiefMaster it is recommended to put width and valign to CSS (note: CSS calls it vertical-align).

1)

<td style="white-space:nowrap; width:237px; vertical-align:top;">

2) We can make a CSS class like this, it is more elegant way

In style section

.td-some-name
{
  white-space:nowrap;
  width:237px;
  vertical-align:top;
}

In HTML section

I'm not fine with solutions that iterates over a collection and inside the loop manipulating the content of even that collection. This can result in unexpected behaviour.

See also here: https://stackoverflow.com/a/2304578/655224 and in a comment the given link http://php.net/manual/en/control-structures.foreach.php#88578

So, when using foreach if seems to be OK but IMHO the much more readable and simple solution is to filter your collection to a new one.

/**
 * Filter all `selected` items
 *
 * @link https://laravel.com/docs/7.x/collections#method-filter
 */
$selected = $collection->filter(function($value, $key) {
    return $value->selected;
})->toArray();

I tried to run insertion of random data into MyISAM and InnoDB tables. The result was quite shocking. MyISAM needed a few seconds less for inserting 1 million rows than InnoDB for just 10 thousand!

I agree with kazanaki's answer, and it helped me. I wanted to select the whole entity, so I used

 select DISTINCT(c) from Customer c

In my case I have many-to-many relationship, and I want to load entities with collections in one query.

I used LEFT JOIN FETCH and at the end I had to make the result distinct.

width, height = map(int, input().split())
def rectanglePerimeter(width, height):
   return ((width + height)*2)
print(rectanglePerimeter(width, height))

Running it like this produces:

% echo "1 2" | test.py
6

I suspect IDLE is simply passing a single string to your script. The first input() is slurping the entire string. Notice what happens if you put some print statements in after the calls to input():

width = input()
print(width)
height = input()
print(height)

Running echo "1 2" | test.py produces

1 2
Traceback (most recent call last):
  File "/home/unutbu/pybin/test.py", line 5, in <module>
    height = input()
EOFError: EOF when reading a line

Notice the first print statement prints the entire string '1 2'. The second call to input() raises the EOFError (end-of-file error).

So a simple pipe such as the one I used only allows you to pass one string. Thus you can only call input() once. You must then process this string, split it on whitespace, and convert the string fragments to ints yourself. That is what

width, height = map(int, input().split())

does.

Note, there are other ways to pass input to your program. If you had run test.py in a terminal, then you could have typed 1 and 2 separately with no problem. Or, you could have written a program with pexpect to simulate a terminal, passing 1 and 2 programmatically. Or, you could use argparse to pass arguments on the command line, allowing you to call your program with

test.py 1 2

TAKE NOTE on the height: 12px.. I made it 12px so it will be noticed on Mac Users as well. But w/ windows, 0.1px is good enough

After read all Answers I came up with elegant way:

public class MyActivity extends ActionBarActivity {

 Fragment fragment ;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    FragmentManager fm = getSupportFragmentManager();
    fragment = fm.findFragmentByTag("myFragmentTag");
    if (fragment == null) {
        FragmentTransaction ft = fm.beginTransaction();
        fragment =new MyFragment();
        ft.add(android.R.id.content,fragment,"myFragmentTag");
        ft.commit();
    }

}

basically you don't need to add a frameLayout as container of your fragment instead you can add straight the fragment into the android root View container

IMPORTANT: don't use replace fragment as most of the approach shown here, unless you don't mind to lose fragment variable instance state during onrecreation process.

I searched for curl on the cygwin packages part of their home page.

I found this link http://cygwin.com/packages/curl/. But that wasn't helpful because I couldn't download anything

So I searched for the curl-7.20.1-1 cygwin on Google. I found this helpful site mirrors.xmission.com/cygwin/release/curl/

That site had a link to download curl-7.20.1-1.tar.bz2. I unzipped it using 7zip. It unzips it into ./user/bin/ or something so I had to find curl.exe in the local /usr/bin folder and put it into my /bin folder of c:\cygwin

Finally I could use cURL!

This drove me crazy. I hope it helps someone!

You can try using the PNG drop shadows. IE6 doesn't support it, however it will degrade nicely.

http://www.positioniseverything.net/articles/dropshadows.html

There is many ways to use it and i recomend you to see this documentation about String Format.

http://developer.android.com/intl/pt-br/reference/java/util/Formatter.html

But, if you need only one variable, you'll need to use %[type] where [type] could be any Flag (see Flag types inside site above). (i.e. "My name is %s" or to set my name UPPERCASE, use this "My name is %S")

<string name="welcome_messages">Hello, %1$S! You have %2$d new message(s) and your quote is %3$.2f%%.</string>

Hello, ANDROID! You have 1 new message(s) and your quote is 80,50%.

One line answer. You can use filter function to get result.

var array = [_x000D_
    { name:"string 1", value:"this", other: "that" },_x000D_
    { name:"string 2", value:"this", other: "that" }_x000D_
];_x000D_
_x000D_
console.log(array.filter(function(arr){return arr.name == 'string 1'})[0]);

If you're not worried about legacy browsers use a flexbox.

The parent element needs its display type set to flex

div.parent {
  display: flex;
  height: 100%;
}

Then you set the child element's align-self to flex-end.

span.child {
  display: inline-block;
  align-self: flex-end;
}

Here's the resource I used to learn: http://css-tricks.com/snippets/css/a-guide-to-flexbox/

The below code gets the full path, where the anchor points:

document.getElementById("aaa").href; // http://example.com/sec/IF00.html

while the one below gets the value of the href attribute:

document.getElementById("aaa").getAttribute("href"); // sec/IF00.html

It calculates e^x for each x in your list where e is Euler's number (approximately 2.718). In other words, np.exp(range(5)) is similar to [math.e**x for x in range(5)].

It really depends on what you want to achieve. If you want to "emulate" strongly typed languages then I suggest you not trying. As others mentioned all numbers have the same representation (the same type).

Using something like Claudiu provided:

isInteger( 1.0 ) -> true

which looks fine for common sense, but in something like C you would get false

In Case of not considering '0' or 'NULL' in average function. Simply use

AVG(NULLIF(your_column_name,0))

If you want to get advantage of your local machine timezone you can use myDateTime.ToUniversalTime() to get the UTC time from your local time or myDateTime.ToLocalTime() to convert the UTC time to the local machine's time.

// convert UTC time from the database to the machine's time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var localTime = databaseUtcTime.ToLocalTime();

// convert local time to UTC for database save
var databaseUtcTime = localTime.ToUniversalTime();

If you need to convert time from/to other timezones, you may use TimeZoneInfo.ConvertTime() or TimeZoneInfo.ConvertTimeFromUtc().

// convert UTC time from the database to japanese time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var japaneseTimeZone = TimeZoneInfo.FindSystemTimeZoneById("Tokyo Standard Time");
var japaneseTime = TimeZoneInfo.ConvertTimeFromUtc(databaseUtcTime, japaneseTimeZone);

// convert japanese time to UTC for database save
var databaseUtcTime = TimeZoneInfo.ConvertTimeToUtc(japaneseTime, japaneseTimeZone);

List of available timezones

I am trying to detect the chrome and safari browser using jquery or javascript.

Use jQuery.browser

I thought we are not supposed to use jQuery.browser.

That's because detecting browsers is a bad idea. It is still the best way to detect the browser (when jQuery is involved) if you really intend to do that.

If you really need the indices you can just do what you said again for the inner list:

l = [[2,2,2],[3,3,3],[4,4,4]]
for index1 in xrange(len(l)):
    for index2 in xrange(len(l[index1])):
        print index1, index2, l[index1][index2]

But it is more pythonic to iterate through the list itself:

for inner_l in l:
    for item in inner_l:
        print item

If you really need the indices you can also use enumerate:

for index1, inner_l in enumerate(l):
    for index2, item in enumerate(inner_l):
        print index1, index2, item, l[index1][index2]

If you are using Visual Studio 2010 or plus then check the target framework that is it .Net Framework 4.0 or .Net Framework 4.0 Client Profile. then change is to .Net Framework 4.0.

You need to add reference this .dll file (System.Drawing.dll) to perform drawing operations.

If it is OK then follow these steps to add reference to System.Drawing.dll

1. In Solution Explorer, right-click on the project node and click Add Reference.
2. In the Add Reference dialog box, select the tab indicating the type of component you want to reference.
3. Select the System.Drawing.dll to reference, then click OK.

The fact that a class implements Comparable means that you can take two objects from that class and compare them. Some classes, like certain collections (sort function in a collection) that keep objects in order rely on them being comparable (in order to sort you need to know which object is the "biggest" and so forth).

Propably this would do it for you.

 $('input').val('').removeAttr('checked').removeAttr('selected');

You can't. The emulator does not support Bluetooth, as mentioned in the SDK's docs and several other places. Android emulator does not have bluetooth capabilities".

You can only use real devices.

Emulator Limitations

The functional limitations of the emulator include:

• No support for placing or receiving actual phone calls. However, You can simulate phone calls (placed and received) through the emulator console
• No support for USB
• No support for device-attached headphones
• No support for determining SD card insert/eject
• No support for WiFi, Bluetooth, NFC

Refer to the documentation

 jquery.ajax({
            url: `//your api url`
            type: "GET",
            dataType: "json",
            success: function(data) {
                jQuery.each(data, function(index, value) {
                        console.log(data);
                        `All you API data is here`
                    }
                }
            });     

Here's a nice answer from the FAQ on the scipy.org website:

What advantages do NumPy arrays offer over (nested) Python lists?

Python’s lists are efficient general-purpose containers. They support (fairly) efficient insertion, deletion, appending, and concatenation, and Python’s list comprehensions make them easy to construct and manipulate. However, they have certain limitations: they don’t support “vectorized” operations like elementwise addition and multiplication, and the fact that they can contain objects of differing types mean that Python must store type information for every element, and must execute type dispatching code when operating on each element. This also means that very few list operations can be carried out by efficient C loops – each iteration would require type checks and other Python API bookkeeping.

This is documented behavior. From ?as.Date:

format: A character string. If not specified, it will try '"%Y-%m-%d"' then '"%Y/%m/%d"' on the first non-'NA' element, and give an error if neither works.

as.Date("01 Jan 2000") yields an error because the format isn't one of the two listed above. as.Date("01/01/2000") yields an incorrect answer because the date isn't in one of the two formats listed above.

I take "standard unambiguous" to mean "ISO-8601" (even though as.Date isn't that strict, as "%m/%d/%Y" isn't ISO-8601).

If you receive this error, the solution is to specify the format your date (or datetimes) are in, using the formats described in ?strptime. Be sure to use particular care if your data contain day/month names and/or abbreviations, as the conversion will depend on your locale (see the examples in ?strptime and read ?LC_TIME).

With GNU awk for inplace editing, \s/\S, and gensub() to delete

1) the FIRST field:

awk -i inplace '{sub(/^\S+\s*/,"")}1' file

or

awk -i inplace '{$0=gensub(/^\S+\s*/,"",1)}1' file

2) the LAST field:

awk -i inplace '{sub(/\s*\S+$/,"")}1' file

or

awk -i inplace '{$0=gensub(/\s*\S+$/,"",1)}1' file

3) the N^th field where N=3:

awk -i inplace '{$0=gensub(/\s*\S+/,"",3)}1' file

Without GNU awk you need a match()+substr() combo or multiple sub()s + vars to remove a middle field. See also Print all but the first three columns.

If you have a unique key, you may use COUNT(*) OVER ( ORDER BY unique_key ) as ROWNUM

SELECT t.*, count(*) OVER (ORDER BY k ) ROWNUM 
FROM yourtable t;

| k |     n | rownum |
|---|-------|--------|
| a | TEST1 |      1 |
| b | TEST2 |      2 |
| c | TEST2 |      3 |
| d | TEST4 |      4 |

DEMO

This will remove all non-alphanumeric characters except spaces.

string = "Special $#! characters   spaces 888323"
''.join(e for e in string if (e.isalnum() or e.isspace()))

Special characters spaces 888323

vim +21490go script.py

From the command line will open the file and take you to position 21490 in the buffer.

Triggering it from the command line like this allows you to automate a script to parse the exception message and open the file to the problem position.

Excerpt from man vim:

+{command}

-c {command}

{command} will be executed after the first file has been read. {command} is interpreted as an Ex command. If the {command} contains spaces it must be enclosed in double quotes (this depends on the shell that is used).

Replace this line : getResources().getDrawable(R.drawable.your_drawable)

with ResourcesCompat.getDrawable(getResources(), R.drawable.your_drawable, null)

EDIT

ResourcesCompat is also deprecated now. But you can use this:

ContextCompat.getDrawable(this, R.drawable.your_drawable) (Here this is the context)

for more details follow this link: ContextCompat

@andrey answer in one line (tested in Swift 4.1):

extension UIResponder {
    public var parentViewController: UIViewController? {
        return next as? UIViewController ?? next?.parentViewController
    }
}

usage:

 let vc: UIViewController = view.parentViewController

Your code would have worked if it had been in this format: YYYY-MM-DD, this is the computer standard for date formats http://en.wikipedia.org/wiki/ISO_8601

You can run the client like this ...

puppet agent --test --debug --noop

with that command you get all the output you can get.

* --test:
  Enable the most common options used for testing. These are 'onetime',
  'verbose', 'ignorecache', 'no-daemonize', 'no-usecacheonfailure',
  'detailed-exitcodes', 'no-splay', and 'show_diff'.

NOTE: No need to include --verbose when you use the --test|-t switch, it implies the --verbose as well.

The easiest way to do so is using jQuery and animate.css animation library.

Javascript

/* --- Show DIV --- */
$( '.example' ).removeClass( 'fadeOutRight' ).show().addClass( 'fadeInRight' );

/* --- Hide DIV --- */
$( '.example' ).removeClass( 'fadeInRight' ).addClass( 'fadeOutRight' );

HTML

<div class="example">Some text over here.</div>

Easy enough to implement. Just don't forget to include the animate.css file in the header :)

In my case, I had a repo with:

• requirements A,B,C,D in .json
• but only A,B,C in the .lock

In the meantime, A,B,C had newer versions with respect when the lock was generated.

For some reason, I deleted the "vendors" and wanted to do a composer install and failed with the message:

Warning: The lock file is not up to date with the latest changes in composer.json.
You may be getting outdated dependencies. Run update to update them.
Your requirements could not be resolved to an installable set of packages.

I tried to run the solution from Seldaek issuing a composer update vendorD/libraryD but composer insisted to update more things, so .lock had too changes seen my my git tool.

The solution I used was:

1. Delete all the vendors dir.
2. Temporarily remove the requirement VendorD/LibraryD from the .json.
3. run composer install.
4. Then delete the file .json and checkout it again from the repo (equivalent to re-adding the file, but avoiding potential whitespace changes).
5. Then run Seldaek's solution composer update vendorD/libraryD

It did install the library, but in addition, git diff showed me that in the .lock only the new things were added without editing the other ones.

(Thnx Seldaek for the pointer ;) )

Based on Ramon's answer I run into an error. The problem where spaces in the JSON I tried to write I got it fixed by changing the task in the playbook to look like:

- copy:
    content: "{{ your_json_feed }}"
    dest: "/path/to/destination/file"

As of now I am not sure why this was needed. My best guess is that it had something to do with how variables are replaced in Ansible and the resulting file is parsed.

You could use the old ways. And use a table. In the table you define 3 columns. You set the width of your whole table and define the width of every colum. that way you can horizantaly space 2 objects. You put object one inside cell1 (colum1, row1) and object2 in cell3 (colum 3, row 1) and you leave cell 2 empty. Given it has a width, you will see empty spaces. example

<table width="500">
    <tr>
        <td width="40%">
            Object 1
        </td>
        <td width="20%">

        </td>
        <td width="40%">
            Object 2
        </td>
    </tr>
</table>

Or you could go the better way with div's. Just put your objects inside divs. Add a middle div and put these 3 divs inside another div. At the css style to the upper div: overflow: auto and define a width. Add css style to the 3 divs to define their width and add float: left example

<div style="overflow: auto;width: 100%;">
    <div style="width:200px;float: left;">
        Object  1
    </div>
    <div style="width:200px;float: left;">

    </div>
    <div style="width:200px;float: left;">
        Object  2
    </div>
</div>

If you know the name of your constraint then you can directly use the command like

alter table users drop constraint constraint_name;

If you don't know the constraint name, you can get the constraint by using this command

select constraint_name,constraint_type from user_constraints where table_name = 'YOUR TABLE NAME';

Copy the global variable to a variable in the scope in your controller.

function MyCtrl($scope) {
   $scope.variable1 = variable1;
}

Then you can just access it like you tried. But note that this variable will not change when you change the global variable. If you need that, you could instead use a global object and "copy" that. As it will be "copied" by reference, it will be the same object and thus changes will be applied (but remember that doing stuff outside of AngularJS will require you to do $scope.$apply anway).

But maybe it would be worthwhile if you would describe what you actually try to achieve. Because using a global variable like this is almost never a good idea and there is probably a better way to get to your intended result.

This is where we appreciate all the power of CSS3:

.bloc {_x000D_
  display: inline-block;_x000D_
  vertical-align: top;_x000D_
  overflow: hidden;_x000D_
  border: solid grey 1px;_x000D_
}_x000D_
_x000D_
.bloc select {_x000D_
  padding: 10px;_x000D_
  margin: -5px -20px -5px -5px;_x000D_
}

<div class="bloc">_x000D_
  <select name="year" size="5">_x000D_
    <option value="2010">2010</option>_x000D_
    <option value="2011">2011</option>_x000D_
    <option value="2012" SELECTED>2012</option>_x000D_
    <option value="2013">2013</option>_x000D_
    <option value="2014">2014</option>_x000D_
  </select>_x000D_
</div>

Fiddle

This explanation is based on a commented Ruby script from a friend of mine. If you want to improve the script, feel free to update it at the link.

First, note that when Ruby calls out to a shell, it typically calls /bin/sh, not Bash. Some Bash syntax is not supported by /bin/sh on all systems.

Here are ways to execute a shell script:

cmd = "echo 'hi'" # Sample string that can be used

1. Kernel#` , commonly called backticks – `cmd`

   This is like many other languages, including Bash, PHP, and Perl.

   Returns the result (i.e. standard output) of the shell command.

   Docs: http://ruby-doc.org/core/Kernel.html#method-i-60

   value = `echo 'hi'`
   value = `#{cmd}`
   

2. Built-in syntax, %x( cmd )

   Following the x character is a delimiter, which can be any character. If the delimiter is one of the characters (, [, {, or <, the literal consists of the characters up to the matching closing delimiter, taking account of nested delimiter pairs. For all other delimiters, the literal comprises the characters up to the next occurrence of the delimiter character. String interpolation #{ ... } is allowed.

   Returns the result (i.e. standard output) of the shell command, just like the backticks.

   Docs: https://docs.ruby-lang.org/en/master/syntax/literals_rdoc.html#label-Percent+Strings

   value = %x( echo 'hi' )
   value = %x[ #{cmd} ]
   

3. Kernel#system

   Executes the given command in a subshell.

   Returns true if the command was found and run successfully, false otherwise.

   Docs: http://ruby-doc.org/core/Kernel.html#method-i-system

   wasGood = system( "echo 'hi'" )
   wasGood = system( cmd )
   

4. Kernel#exec

   Replaces the current process by running the given external command.

   Returns none, the current process is replaced and never continues.

   Docs: http://ruby-doc.org/core/Kernel.html#method-i-exec

   exec( "echo 'hi'" )
   exec( cmd ) # Note: this will never be reached because of the line above
   

Here's some extra advice: $?, which is the same as $CHILD_STATUS, accesses the status of the last system executed command if you use the backticks, system() or %x{}. You can then access the exitstatus and pid properties:

$?.exitstatus

For more reading see:

• http://www.elctech.com/blog/i-m-in-ur-commandline-executin-ma-commands
• http://blog.jayfields.com/2006/06/ruby-kernel-system-exec-and-x.html
• http://tech.natemurray.com/2007/03/ruby-shell-commands.html

You can do it in two ways:

First:

render() {
    const data =[{"name":"test1"},{"name":"test2"}];
    const listItems = data.map((d) => <li key={d.name}>{d.name}</li>);

    return (
      <div>
      {listItems }
      </div>
    );
  }

Second: Directly write the map function in the return

render() {
    const data =[{"name":"test1"},{"name":"test2"}];
    return (
      <div>
      {data.map(function(d, idx){
         return (<li key={idx}>{d.name}</li>)
       })}
      </div>
    );
  }

You can use this as well

import numpy as np
x=np.array(['1.1', '2.2', '3.3'])
x=np.asfarray(x,float)

div hover background color change

Try like this:

.class_name:hover{
    background-color:#FF0000;
}

For SOCK_STREAM socket, the buffer size does not really matter, because you are just pulling some of the waiting bytes and you can retrieve more in a next call. Just pick whatever buffer size you can afford.

For SOCK_DGRAM socket, you will get the fitting part of the waiting message and the rest will be discarded. You can get the waiting datagram size with the following ioctl:

#include <sys/ioctl.h>
int size;
ioctl(sockfd, FIONREAD, &size);

Alternatively you can use MSG_PEEK and MSG_TRUNC flags of the recv() call to obtain the waiting datagram size.

ssize_t size = recv(sockfd, buf, len, MSG_PEEK | MSG_TRUNC);

You need MSG_PEEK to peek (not receive) the waiting message - recv returns the real, not truncated size; and you need MSG_TRUNC to not overflow your current buffer.

Then you can just malloc(size) the real buffer and recv() datagram.

This is the code I'm using right now for a website I'm making that needs to get the leading paragraphs / summary / section 0 of off Wikipedia articles, and it's all done within the browser (client side javascript) thanks to the magick of JSONP! --> http://jsfiddle.net/gautamadude/HMJJg/1/

It uses the Wikipedia API to get the leading paragraphs (called section 0) in HTML like so: http://en.wikipedia.org/w/api.php?format=json&action=parse&page=Stack_Overflow&prop=text&section=0&callback=?

It then strips the HTML and other undesired data, giving you a clean string of an article summary, if you want you can, with a little tweaking, get a "p" html tag around the leading paragraphs but right now there is just a newline character between them.

Code:

var url = "http://en.wikipedia.org/wiki/Stack_Overflow";
var title = url.split("/").slice(4).join("/");

//Get Leading paragraphs (section 0)
$.getJSON("http://en.wikipedia.org/w/api.php?format=json&action=parse&page=" + title + "&prop=text&section=0&callback=?", function (data) {
    for (text in data.parse.text) {
        var text = data.parse.text[text].split("<p>");
        var pText = "";

        for (p in text) {
            //Remove html comment
            text[p] = text[p].split("<!--");
            if (text[p].length > 1) {
                text[p][0] = text[p][0].split(/\r\n|\r|\n/);
                text[p][0] = text[p][0][0];
                text[p][0] += "</p> ";
            }
            text[p] = text[p][0];

            //Construct a string from paragraphs
            if (text[p].indexOf("</p>") == text[p].length - 5) {
                var htmlStrip = text[p].replace(/<(?:.|\n)*?>/gm, '') //Remove HTML
                var splitNewline = htmlStrip.split(/\r\n|\r|\n/); //Split on newlines
                for (newline in splitNewline) {
                    if (splitNewline[newline].substring(0, 11) != "Cite error:") {
                        pText += splitNewline[newline];
                        pText += "\n";
                    }
                }
            }
        }
        pText = pText.substring(0, pText.length - 2); //Remove extra newline
        pText = pText.replace(/\[\d+\]/g, ""); //Remove reference tags (e.x. [1], [4], etc)
        document.getElementById('textarea').value = pText
        document.getElementById('div_text').textContent = pText
    }
});

From Python 3.4 on, the best way to check if an IPv6 or IPv4 address is correct, is to use the Python Standard Library module ipaddress - IPv4/IPv6 manipulation library s.a. https://docs.python.org/3/library/ipaddress.html for complete documentation.

Example :

#!/usr/bin/env python

import ipaddress
import sys

try:
    ip = ipaddress.ip_address(sys.argv[1])
    print('%s is a correct IP%s address.' % (ip, ip.version))
except ValueError:
    print('address/netmask is invalid: %s' % sys.argv[1])
except:
    print('Usage : %s  ip' % sys.argv[0])

For other versions: Github, phihag / Philipp Hagemeister,"Python 3.3's ipaddress for older Python versions", https://github.com/phihag/ipaddress

The backport from phihag is available e.g. in Anaconda Python 2.7 & is included in Installer. s.a. https://docs.continuum.io/anaconda/pkg-docs

To install with pip:

pip install ipaddress

s.a.: ipaddress 1.0.17, "IPv4/IPv6 manipulation library", "Port of the 3.3+ ipaddress module", https://pypi.python.org/pypi/ipaddress/1.0.17

Rounding up to the next 0.05, I would do this way:

def roundup(x):
    return round(int(math.ceil(x / 0.05)) * 0.05,2)

TL;DR

You are missing the @Id entity property, and that's why Hibernate is throwing that exception.

Entity identifiers

Any JPA entity must have an identifier property, that is marked with the Id annotation.

There are two types of identifiers:

• assigned
• auto-generated

Assigned identifiers

An assigned identifier looks as follows:

@Id
private Long id;

Notice that we are using a wrapper (e.g., Long, Integer) instead of a primitive type (e.g., long, int). Using a wrapper type is a better choice when using Hibernate because, by checking if the id is null or not, Hibernate can better determine if an entity is transient (it does not have an associated table row) or detached (it has an associated table row, but it's not managed by the current Persistence Context).

The assigned identifier must be set manually by the application prior to calling persist:

Post post = new Post();
post.setId(1L);

entityManager.persist(post);

Auto-generated identifiers

An auto-generated identifier requires the @GeneratedValue annotation besides the @Id:

@Id
@GeneratedValue
private int id;

There are 3 strategies Hibernate can use to auto-generate the entity identifier:

• IDENTITY
• SEQUENCE
• TABLE

The IDENTITY strategy is to be avoided if the underlying database supports sequences (e.g., Oracle, PostgreSQL, MariaDB since 10.3, SQL Server since 2012). The only major database that does not support sequences is MySQL.

The problem with IDENTITY is that automatic Hibernate batch inserts are disabled for this strategy.

The SEQUENCE strategy is the best choice unless you are using MySQL. For the SEQUENCE strategy, you also want to use the pooled optimizer to reduce the number of database roundtrips when persisting multiple entities in the same Persistence Context.

The TABLE generator is a terrible choice because it does not scale. For portability, you are better off using SEQUENCE by default and switch to IDENTITY for MySQL only.

If you are on production server and the .env file doesn't work at all, go to /bootstrap/cache/config.php and on the line 230 more or less you will find the database data that is beeing cached from the .env file.

'mysql' => 
  array (
    'driver' => 'mysql',
    'host' => '127.0.0.1',
    'port' => '3306',
    'database' => 'yorDBname',
    'username' => 'YOURUSERNAME',
    'password' => 'yourpass',
    'unix_socket' => '',
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    'prefix' => '',
    'strict' => true,
    'engine' => 'InnoDB ROW_FORMAT=DYNAMIC',
  ),

As it's an issue we face more than often, below are the steps to resolve it.

1. Open the Git perspective. In the Git Repository view, go to on Branches ? Local ? master and right click ? Merge...

2. It should auto select Remote Tracking ? *origin/master. Press Merge.

3. Launch stage view in Eclipse.

4. Double click the files which initially showed conflict

5. In the conflict merge view, by selecting the left arrow for all the non-conflict + conflict changes from left to right, you can resolve all the conflicts.

6. Save the merged file.

7. Do a Team ? pull from Eclipse again.

You are all set :)

Firstly, BEGIN..END are merely syntactic elements, and have nothing to do with transactions.

Secondly, in Oracle all individual DML statements are atomic (i.e. they either succeed in full, or rollback any intermediate changes on the first failure) (unless you use the EXCEPTIONS INTO option, which I won't go into here).

If you wish a group of statements to be treated as a single atomic transaction, you'd do something like this:

BEGIN
  SAVEPOINT start_tran;
  INSERT INTO .... ; -- first DML
  UPDATE .... ; -- second DML
  BEGIN ... END; -- some other work
  UPDATE .... ; -- final DML
EXCEPTION
  WHEN OTHERS THEN
    ROLLBACK TO start_tran;
    RAISE;
END;

That way, any exception will cause the statements in this block to be rolled back, but any statements that were run prior to this block will not be rolled back.

Note that I don't include a COMMIT - usually I prefer the calling process to issue the commit.

It is true that a BEGIN..END block with no exception handler will automatically handle this for you:

BEGIN
  INSERT INTO .... ; -- first DML
  UPDATE .... ; -- second DML
  BEGIN ... END; -- some other work
  UPDATE .... ; -- final DML
END;

If an exception is raised, all the inserts and updates will be rolled back; but as soon as you want to add an exception handler, it won't rollback. So I prefer the explicit method using savepoints.

string = string.replace(/[\W_]/g, "_");

Download and Install Administrative Templates for Windows PowerShell

Next:  Powershell x86 from As Administrator

Run:   Get-ExecutionPolicy -List  , and see if you have RemoteSigned etc..

1. 5 different scopes  Set-ExecutionPolicy "RemoteSigned" -Scope Process -Confirm:$false

2. Machine and User Policy you have to set through the Group Policy Administration Template in 2 areas.

UPDATE - EDIT:

Set ALL of them to  "Undefined" and ONLY the LocalMachine to "Restricted" 

This is what fixed might after I had given my powershell more permissions not knowing that it would mess up visual studio 2013 and 2015

Basic difference is that Google App Engine (GAE) is a Platform as a Service (PaaS) whereas Google Compute Engine (GCE) is an Infrastructure as a Service (IaaS).

To run your application in GAE you just need to write your code and deploy it into GAE, no other headache. Since GAE is fully scalable, it will automatically acquire more instances in case the traffic goes higher and decrease the instances when traffic decreases. You will be charged for the resources you really use, I mean, you will be billed for the Instance-Hours, Transferred Data, Storage etc your app really used. But the restriction is, you can create your application in only Python, PHP, Java, NodeJS, .NET, Ruby and **Go.

On the other hand, GCE provides you full infrastructure in the form of Virtual Machine. You have complete control over those VMs' environment and runtime as you can write or install any program there. Actually GCE is the way to use Google Data Centers virtually. In GCE you have to manually configure your infrastructure to handle scalability by using Load Balancer.

Both GAE and GCE are part of Google Cloud Platform.

Update: In March 2014 Google announced a new service under App Engine named Managed Virtual Machine. Managed VMs offers app engine applications a bit more flexibility over app platform, CPU and memory options. Like GCE you can create a custom runtime environment in these VMs for app engine application. Actually Managed VMs of App Engine blurs the frontier between IAAS and PAAS to some extent.

There are a few arguments (one of which is relatively recent) which I believe contradict Bjarne's position on this.

1. Documentation of intent

   Using NULL allows for searches on its use and it also highlights that the developer wanted to use a NULL pointer, irrespective of whether it is being interpreted by the compiler as NULL or not.

2. Overload of pointer and 'int' is relatively rare

   The example that everybody quotes is:

    void foo(int*);
    void foo (int);
   
    void bar() {
      foo (NULL);  // Calls 'foo(int)'
    }
   

   However, at least in my opinion, the problem with the above is not that we're using NULL for the null pointer constant: it's that we have overloads of foo() which take very different kinds of arguments. The parameter must be an int too, as any other type will result in an ambiguous call and so generate a helpful compiler warning.

3. Analysis tools can help TODAY!

   Even in the absence of C++0x, there are tools available today that verify that NULL is being used for pointers, and that 0 is being used for integral types.

4. C++ 11 will have a new std::nullptr_t type.

   This is the newest argument to the table. The problem of 0 and NULL is being actively addressed for C++0x, and you can guarantee that for every implementation that provides NULL, the very first thing that they will do is:

    #define NULL  nullptr
   

   For those who use NULL rather than 0, the change will be an improvement in type-safety with little or no effort - if anything it may also catch a few bugs where they've used NULL for 0. For anybody using 0 today... well, hopefully they have a good knowledge of regular expressions...

In SQLite this is simpler. I think there are similar implementations for MySQL, MSSql and Orable

CREATE TABLE Beatles (id integer, name string );
INSERT INTO Beatles VALUES (1, "Paul");
INSERT INTO Beatles VALUES (2, "John");
INSERT INTO Beatles VALUES (3, "Ringo");
INSERT INTO Beatles VALUES (4, "George");
SELECT GROUP_CONCAT(name, ',') FROM Beatles;

http://docs.oracle.com/javase/7/docs/api/javax/swing/JTable.html

You will find these methods in it:

getValueAt(int row, int column)
getSelectedRow()
getSelectedColumn()

Use a mix of these to achieve your result.

Inf is infinity, it's a "bigger than all the other numbers" number. Try subtracting anything you want from it, it doesn't get any smaller. All numbers are < Inf. -Inf is similar, but smaller than everything.

NaN means not-a-number. If you try to do a computation that just doesn't make sense, you get NaN. Inf - Inf is one such computation. Usually NaN is used to just mean that some data is missing.

• for better performace use the biggest blocksize you RAM can accomodate (will send less I/O calls to the OS)
• for better accurancy and data recovery set the blocksize to the native sector size of the input

As dd copies data with the conv=noerror,sync option, any errors it encounters will result in the remainder of the block being replaced with zero-bytes. Larger block sizes will copy more quickly, but each time an error is encountered the remainder of the block is ignored.

I use below function to animate UiKit gear icon using Just JavaScript

document.getElementById("spin_it").onmouseover=function(e){_x000D_
var el = document.getElementById("spin_it");_x000D_
var Classes = el.className;_x000D_
var NewClass = Classes+" uk-icon-spin";_x000D_
el.className = NewClass;_x000D_
console.log(e);_x000D_
}

<span class="uk-icon uk-icon-small uk-icon-gear" id="spin_it"></span>

This code not work here...you must add UIKit Style to it

Use simplest way of doing this-

SELECT GROUP_CONCAT(Column) from table

If you need to handle values that cannot be converted separately, you can use this method:

try {
    $valueToUse = trim($stringThatMightBeNumeric) + 0;
} catch (\Throwable $th) {
    // bail here if you need to
}

Here is OOP:

import MySQLdb


class Database:

    host = 'localhost'
    user = 'root'
    password = '123'
    db = 'test'

    def __init__(self):
        self.connection = MySQLdb.connect(self.host, self.user, self.password, self.db)
        self.cursor = self.connection.cursor()

    def insert(self, query):
        try:
            self.cursor.execute(query)
            self.connection.commit()
        except:
            self.connection.rollback()



    def query(self, query):
        cursor = self.connection.cursor( MySQLdb.cursors.DictCursor )
        cursor.execute(query)

        return cursor.fetchall()

    def __del__(self):
        self.connection.close()


if __name__ == "__main__":

    db = Database()

    #CleanUp Operation
    del_query = "DELETE FROM basic_python_database"
    db.insert(del_query)

    # Data Insert into the table
    query = """
        INSERT INTO basic_python_database
        (`name`, `age`)
        VALUES
        ('Mike', 21),
        ('Michael', 21),
        ('Imran', 21)

    # db.query(query)
    db.insert(query)

    # Data retrieved from the table
    select_query = """
        SELECT * FROM basic_python_database
        WHERE age = 21
        """

    people = db.query(select_query)

    for person in people:
        print "Found %s " % person['name']

Just in caser anyone ends here like me. In may case despite having enabled unsecure access to my google account, it refused to send the email throwing an SMTP ERROR: Password command failed: 534-5.7.14.

(Solution found at https://know.mailsbestfriend.com/smtp_error_password_command_failed_5345714-1194946499.shtml)

Steps:

1. log into your google account

2. Go to https://accounts.google.com/b/0/DisplayUnlockCaptcha and click continue to enable.

3. Setup your phpmailer as smtp with ssl:

   $mail = new PHPMailer(true);
   
   $mail->CharSet  ="utf-8";
   $mail->SMTPDebug = SMTP::DEBUG_SERVER; // or 0 for no debuggin at all        
   $mail->isSMTP();
   $mail->Host = 'smtp.gmail.com';
   $mail->Port = 465; 
   $mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS; 
   $mail->SMTPAuth   = true;
   $mail->Username = 'yourgmailaccount';
   $mail->Password = 'yourpassword';
   

And the other $mail object properties as needed.

Hope it helps someone!!

Option 1 using an InputStreamResource

Resource implementation for a given InputStream.

Should only be used if no other specific Resource implementation is > applicable. In particular, prefer ByteArrayResource or any of the file-based Resource implementations where possible.

@RequestMapping(path = "/download", method = RequestMethod.GET)
public ResponseEntity<Resource> download(String param) throws IOException {

    // ...

    InputStreamResource resource = new InputStreamResource(new FileInputStream(file));

    return ResponseEntity.ok()
            .headers(headers)
            .contentLength(file.length())
            .contentType(MediaType.APPLICATION_OCTET_STREAM)
            .body(resource);
}

Option2 as the documentation of the InputStreamResource suggests - using a ByteArrayResource:

@RequestMapping(path = "/download", method = RequestMethod.GET)
public ResponseEntity<Resource> download(String param) throws IOException {

    // ...

    Path path = Paths.get(file.getAbsolutePath());
    ByteArrayResource resource = new ByteArrayResource(Files.readAllBytes(path));

    return ResponseEntity.ok()
            .headers(headers)
            .contentLength(file.length())
            .contentType(MediaType.APPLICATION_OCTET_STREAM)
            .body(resource);
}

Enter in a command prompt window ping /? and read the short help output after pressing RETURN. Or take a look on

• Ping - Windows XP documentation
• Ping - Microsoft TechNet article

Explanation for option -t given by Microsoft:

Pings the specified host until stopped. To see statistics and continue type Control-Break. To stop type Control-C.

You may want to use:

@%SystemRoot%\system32\ping.exe -n 1 www.google.de

Or to check first if a server is available:

@echo off
set MyServer=Server.MyDomain.de
%SystemRoot%\system32\ping.exe -n 1 %MyServer% >nul
if errorlevel 1 goto NoServer

echo %MyServer% is availabe.
rem Insert commands here, for example 1 or more net use to connect network drives.
goto :EOF

:NoServer
echo %MyServer% is not availabe yet.
pause
goto :EOF

set number set nonumber

DO work inside .vimrc and make sure you DO NOT precede commands in .vimrc with :

The glob2 package supports wild cards and is reasonably fast

timeit.timeit(code, number=1)

On my laptop it takes approximately 2 seconds to match >60,000 file paths.

Here's a derived HorizontalScrollView I wrote to handle notifications about scrolling and scroll ending. It properly handles when a user has stopped actively scrolling and when it fully decelerates after a user lets go:

public class ObservableHorizontalScrollView extends HorizontalScrollView {
    public interface OnScrollListener {
        public void onScrollChanged(ObservableHorizontalScrollView scrollView, int x, int y, int oldX, int oldY);
        public void onEndScroll(ObservableHorizontalScrollView scrollView);
    }

    private boolean mIsScrolling;
    private boolean mIsTouching;
    private Runnable mScrollingRunnable;
    private OnScrollListener mOnScrollListener;

    public ObservableHorizontalScrollView(Context context) {
        this(context, null, 0);
    }

    public ObservableHorizontalScrollView(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public ObservableHorizontalScrollView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        int action = ev.getAction();

        if (action == MotionEvent.ACTION_MOVE) {
            mIsTouching = true;
            mIsScrolling = true;
        } else if (action == MotionEvent.ACTION_UP || action == MotionEvent.ACTION_CANCEL) {
            if (mIsTouching && !mIsScrolling) {
                if (mOnScrollListener != null) {
                    mOnScrollListener.onEndScroll(this);
                }
            }

            mIsTouching = false;
        }

        return super.onTouchEvent(ev);
    }

    @Override
    protected void onScrollChanged(int x, int y, int oldX, int oldY) {
        super.onScrollChanged(x, y, oldX, oldY);

        if (Math.abs(oldX - x) > 0) {
            if (mScrollingRunnable != null) {
                removeCallbacks(mScrollingRunnable);
            }

            mScrollingRunnable = new Runnable() {
                public void run() {
                    if (mIsScrolling && !mIsTouching) {
                        if (mOnScrollListener != null) {
                            mOnScrollListener.onEndScroll(ObservableHorizontalScrollView.this);
                        }
                    }

                    mIsScrolling = false;
                    mScrollingRunnable = null;
                }
            };

            postDelayed(mScrollingRunnable, 200);
        }

        if (mOnScrollListener != null) {
            mOnScrollListener.onScrollChanged(this, x, y, oldX, oldY);
        }
    }

    public OnScrollListener getOnScrollListener() {
        return mOnScrollListener;
    }

    public void setOnScrollListener(OnScrollListener mOnEndScrollListener) {
        this.mOnScrollListener = mOnEndScrollListener;
    }

}

Do not use authorization instead of authentication. I should get whole access to service all clients with header. The working code is :

public class TokenAuthenticationHandler : AuthenticationHandler<TokenAuthenticationOptions> 
{
    public IServiceProvider ServiceProvider { get; set; }

    public TokenAuthenticationHandler (IOptionsMonitor<TokenAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock, IServiceProvider serviceProvider) 
        : base (options, logger, encoder, clock) 
    {
        ServiceProvider = serviceProvider;
    }

    protected override Task<AuthenticateResult> HandleAuthenticateAsync () 
    {
        var headers = Request.Headers;
        var token = "X-Auth-Token".GetHeaderOrCookieValue (Request);

        if (string.IsNullOrEmpty (token)) {
            return Task.FromResult (AuthenticateResult.Fail ("Token is null"));
        }           

        bool isValidToken = false; // check token here

        if (!isValidToken) {
            return Task.FromResult (AuthenticateResult.Fail ($"Balancer not authorize token : for token={token}"));
        }

        var claims = new [] { new Claim ("token", token) };
        var identity = new ClaimsIdentity (claims, nameof (TokenAuthenticationHandler));
        var ticket = new AuthenticationTicket (new ClaimsPrincipal (identity), this.Scheme.Name);
        return Task.FromResult (AuthenticateResult.Success (ticket));
    }
}

Startup.cs :

#region Authentication
services.AddAuthentication (o => {
    o.DefaultScheme = SchemesNamesConst.TokenAuthenticationDefaultScheme;
})
.AddScheme<TokenAuthenticationOptions, TokenAuthenticationHandler> (SchemesNamesConst.TokenAuthenticationDefaultScheme, o => { });
#endregion

And mycontroller.cs

[Authorize(AuthenticationSchemes = SchemesNamesConst.TokenAuthenticationDefaultScheme)]
public class MainController : BaseController
{ ... }

I can't find TokenAuthenticationOptions now, but it was empty. I found the same class PhoneNumberAuthenticationOptions :

public class PhoneNumberAuthenticationOptions : AuthenticationSchemeOptions
{
    public Regex PhoneMask { get; set; }// = new Regex("7\\d{10}");
}

You should define static class SchemesNamesConst. Something like:

public static class SchemesNamesConst
{
    public const string TokenAuthenticationDefaultScheme = "TokenAuthenticationScheme";
}

In my case there was no start command in the script section of package.json file. When I created the package.json file with npm init I did not create a start script command. So I went to the package.json file, under scripts I added a new entry:

 "scripts": {
    "start": "node index.js"
  },

Saved it and uploaded to Heroku and it worked

I think you're looking for SELECT INTO:

select test_table.name into name from test_table where id = x;

That will pull the name from test_table where id is your function's argument and leave it in the name variable. Don't leave out the table name prefix on test_table.name or you'll get complaints about an ambiguous reference.

If, like me, you had dynamically created buttons on your page, the

$("#your-bs-button's-id").on("click", function(event) {
                       or
$(".your-bs-button's-class").on("click", function(event) {

methods won't work because they only work on current elements (not future elements). Instead you need to reference a parent item that existed at the initial loading of the web page.

$(document).on("click", "#your-bs-button's-id", function(event) {
                       or more generally
$("#pre-existing-element-id").on("click", ".your-bs-button's-class", function(event) {

There are many other references to this issue on stack overflow here and here.

The function parse_str() automatically reads all query parameters into an array.

For example, if the URL is http://www.example.com/page.php?x=100&y=200, the code

$queries = array();
parse_str($_SERVER['QUERY_STRING'], $queries);

will store parameters into the $queries array ($queries['x']=100, $queries['y']=200).

Look at documentation of parse_str

EDIT

According to the PHP documentation, parse_str() should only be used with a second parameter. Using parse_str($_SERVER['QUERY_STRING']) on this URL will create variables $x and $y, which makes the code vulnerable to attacks such as http://www.example.com/page.php?authenticated=1.

You basically have two choices:

1.Require an instance:

public Navigation(T t) {     this("", "", t); } 

2.Require a class instance:

public Navigation(Class<T> c) {     this("", "", c.newInstance()); } 

You could use a factory pattern, but ultimately you'll face this same issue, but just push it elsewhere in the code.

try some thing like blow:

SString otherParametersUrServiceNeed =  "Company=acompany&Lng=test&MainPeriod=test&UserID=123&CourseDate=8:10:10";
String request = "http://android.schoolportal.gr/Service.svc/SaveValues";

URL url = new URL(request); 
HttpURLConnection connection = (HttpURLConnection) url.openConnection();   
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setInstanceFollowRedirects(false); 
connection.setRequestMethod("POST"); 
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
connection.setRequestProperty("charset", "utf-8");
connection.setRequestProperty("Content-Length", "" + Integer.toString(otherParametersUrServiceNeed.getBytes().length));
connection.setUseCaches (false);

DataOutputStream wr = new DataOutputStream(connection.getOutputStream ());
wr.writeBytes(otherParametersUrServiceNeed);

   JSONObject jsonParam = new JSONObject();
jsonParam.put("ID", "25");
jsonParam.put("description", "Real");
jsonParam.put("enable", "true");

wr.writeBytes(jsonParam.toString());

wr.flush();
wr.close();

You have to use the plugin manager of Notepad++ and search for the JSON plugin. There you can easily install it.

This answer explains it pretty good: How to reformat JSON in Notepad++?

I found that if you have comments in your build.gradle it may break when you try to add a new support library. So make sure you check your build.gradle and see if it looks alright manually.

Subtract two date get the difference in millisecond, if you get 0 it's the same date

function areSameDate(d1, d2){
    return d1 - d2 === 0
}

I was looking for fast way to do the subject, so I made some experiments with suggested ways. And I was surprised by results, so I want to share it with you.

Experiments were done using pythonbenchmark tool and with

a = range(1,50000) # Source list
b = range(1,15000) # Items to remove

Results:

 def comprehension(a, b):
     return [x for x in a if x not in b]

5 tries, average time 12.8 sec

def filter_function(a, b):
    return filter(lambda x: x not in b, a)

5 tries, average time 12.6 sec

def modification(a,b):
    for x in b:
        try:
            a.remove(x)
        except ValueError:
            pass
    return a

5 tries, average time 0.27 sec

def set_approach(a,b):
    return list(set(a)-set(b))

5 tries, average time 0.0057 sec

Also I made another measurement with bigger inputs size for the last two functions

a = range(1,500000)
b = range(1,100000)

And the results:

For modification (remove method) - average time is 252 seconds For set approach - average time is 0.75 seconds

So you can see that approach with sets is significantly faster than others. Yes, it doesn't keep similar items, but if you don't need it - it's for you. And there is almost no difference between list comprehension and using filter function. Using 'remove' is ~50 times faster, but it modifies source list. And the best choice is using sets - it's more than 1000 times faster than list comprehension!

Alternative escaping syntax:

LIKE Wildcard Literals

The JDBC driver supports the {escape 'escape character'} syntax for using LIKE clause wildcards as literals.

SELECT *
FROM tab
WHERE col LIKE 'a\_c' {escape '\'};

You could try this:

git reset --hard HEAD
git pull

(from How do I force "git pull" to overwrite local files?)

Another idea would be to delete the entire git and make a new clone.

if you have two maps lets say map1 and map2 then using java8 Streams,we can compare maps using code below.But it is recommended to use equals rather then != or ==

boolean b = map1.entrySet().stream().filter(value -> 
            map2.entrySet().stream().anyMatch(value1 -> 
            (value1.getKey().equals(value.getKey()) && 
  value1.getValue().equals(value.getValue())))).findAny().isPresent();   


System.out.println("comparison  "+b);

if you give a 2D array to the plot function of matplotlib it will assume the columns to be lines:

If x and/or y is 2-dimensional, then the corresponding columns will be plotted.

In your case your shape is not accepted (100, 1, 1, 8000). As so you can using numpy squeeze to solve the problem quickly:

np.squeez doc: Remove single-dimensional entries from the shape of an array.

import numpy as np
import matplotlib.pyplot as plt

data = np.random.randint(3, 7, (10, 1, 1, 80))
newdata = np.squeeze(data) # Shape is now: (10, 80)
plt.plot(newdata) # plotting by columns
plt.show()

But notice that 100 sets of 80 000 points is a lot of data for matplotlib. I would recommend that you look for an alternative. The result of the code example (run in Jupyter) is:

I've had the same problem as you and I installed Microsoft rdlc designer to solve my problem.

And if you already installed this but still can't found rdlc designer try open visual studio > tools > Extension and Updates > then enable Miscrosoft Rdlc designer extensions.
